This application is a Continuation-In-Part application of U.S. patent application Ser. No. 19/070,837, filed on Mar. 5, 2025, which is a Continuation-In-Part application of U.S. patent application Ser. No. 18/667,507, filed on May 17, 2024, which claims priority to Chinese Patent Application No. 202420883413.8, filed Apr. 26, 2024, each of which is entirely incorporated herein by reference.

The present application relates to the technical field of decorative trees, and in particular to a customizable decorative tree.

A decorative tree is a scene prop, often an artificial plant mimicking a natural tree, which can be customized according to the scene or the user's preferences. However, existing decorative trees are often functionally singular and lack modular connectivity for varying heights, making it difficult for users to achieve a high degree of DIY customization. To address these issues, the applicant has developed a decorative tree with shared and standardized electrified interfaces, providing greater design freedom for users to customize the decorative tree.

Terms like “joint”, “attach” and “set” used in the present disclosure should be understood in a broad sense, for example, may indicate a direct connection or indirect connection through intermediate components; and it may be a wired electrical connection, a radio connection, or a wireless communication signal connection. The exact meanings of the above terms may slightly differ and should be derived from the actual situation by technicians skilled in the art accordingly.

As shown in, in this embodiment, a customizable decorative tree is provided. The decorative tree primarily comprises three fundamental and cooperative components: a trunk configured for sectional assembly and disassembly, a baseconfigured to provide stable support and power input, and a top sectiondisposed at an upper end of the trunk. These components are seamlessly connected via carefully designed shared connectors and electrical connectors, thereby providing the decorative tree with unprecedented configurability, expandability, and user interactivity.

The trunk is formed by a plurality of independent tree sectionsconnected in series. The design of these tree sectionsdraws inspiration from the natural growth patterns and morphological features of real trees. Accordingly, the tree sectionscan be composed of sections with varying heights and diameters. For example, tree sections closer to the base typically have a larger diameter and greater wall thickness to provide better structural stability, while the diameter of the tree sections gradually decreases towards the top, culminating in a slender top section. This tapered design not only provides the decorative tree with a more natural and realistic visual appearance, avoiding the abrupt transitions of conventional artificial trees but also offers significant flexibility for creating special artistic shapes or abstract designs. A user can mix and match tree sections of different sizes, textures, or colors according to their aesthetic preferences and can even create non-traditional, sculptural art installations.

Each tree sectionis typically manufactured from lightweight yet high-strength materials, such as engineering plastics (e.g., high-strength ABS, PC, or nylon), composite materials (e.g., fiberglass-reinforced plastic), or lightweight alloys. The choice of these materials ensures sufficient structural strength to support the entire weight of the tree section while also considering the product's portability and ease of assembly. The interior of a trunk is generally designed to be hollow, accommodating and protecting internal power lines, LED beads, control circuit boards, and other electronic components. The external surface of the tree sectioncan be treated in various ways, for example, with a realistic simulated bark texture, a smooth modern matte or high-gloss finish, or sprayed with various colors and patterns to suit different decorative styles and themes. This modular design also allows for easy replacement of a single tree sectionif it becomes damaged, enhancing the product's maintainability and service life.

The primary function of the baseis to provide stable and reliable support for the entire trunk, ensuring the decorative tree remains upright and stable in various environments. Concurrently, the baseserves as the access point for external power, responsible for transmitting electrical power to the entire trunk system. The baseis selectively connectable to the lowermost tree section. This detachability allows users to replace the base with different styles, sizes, or functionalities as needed. For example, a user could choose a traditional round, square, or polygonal base or select a smart base with integrated additional functions, such as a built-in Bluetooth speaker, ambient light sensor, aromatherapy diffuser, or a small projector. The interior of the basetypically houses a power adapter, a main control circuit board, and the electrical connector for connecting to the lowermost tree section, ensuring effective power management and transmission. The design of the baseshould also account for weight distribution to ensure stability even when the top of the trunk is heavily loaded (e.g., with a large top ornament).

The top section, disposed at the highest point of the trunk, serves a primarily decorative function. The top sectionalso features a detachable design and connects to the uppermost tree sectionvia a shared connector and an electrical connector. This design grants the user great freedom to change top ornaments according to different holiday themes, seasonal changes, or personal preferences. Examples include traditional five-pointed stars, spheres, angel figures, or more modern elements like LED light modules, small display screens, or even a smart ornament integrated with a weather sensor. The top sectioncan be more than just a simple ornament; it can be a smart component integrating special lighting effects, a sound player, or a wireless communication module. Its detachability allows the user to conveniently store it or remove it when not in use, extending its lifespan.

Shared connectorsare disposed between the various tree sections. These connectors are designed to provide diverse, reliable, and user-friendly mechanical connection solutions that meet the requirements of various application scenarios, including connection strength, convenience, stability, and anti-rotation characteristics. Each connector type is carefully designed to ensure that the tree sections can be securely joined and to provide precise physical alignment for the subsequent electrical connection.

Referring to, a typical shared connectorcan be designed as a threaded connection. Specifically, a connecting end of a first tree sectionis provided with a threaded sectionin the form of external threads. A second tree section, which is selectively connectable to the first tree section, is provided with a threaded grooveon the inner side of its corresponding connecting end, where the threaded groovehas a pitch, thread profile, and diameter that precisely match the threaded section. During assembly, a user can simply align the tree section, having the threaded section, with the threaded grooveand rotate it to achieve a tight and secure connection between the two tree sections.

The advantages of a threaded connection are significant. First, it provides extremely high connection strength and reliability. The engagement mechanism of the threads ensures strong axial and radial retention forces, effectively resisting external tension, compression, bending, or torsion and preventing the tree sectionsfrom loosening or detaching due to accidental impacts, vibrations, or prolonged use. Second, the threaded connection offers precise positioning capability; the thread-guiding mechanism enables the tree sectionsto align accurately, which is particularly important for electrical connectors that require precise contact alignment. Third, the threaded connection has excellent reusability, allowing the user to assemble and disassemble it multiple times without significantly affecting connection performance. For disassembly, a simple reverse rotation is all that is required. To enhance operational convenience, the pitch of the threaded sectionand the threaded groovecan be optimized based on the size of the tree sectionsand the expected connection strength, for example, by using coarse threads to expedite assembly. To extend the service life of the threads during frequent assembly and disassembly and to reduce wear, wear-resistant materials such as high-strength alloys are selected, or the thread surfaces are specially treated, such as with anodizing, nickel plating, or a Polytetrafluoroethylene (PTFE) coating, to reduce the coefficient of friction and improve corrosion resistance. Furthermore, a stop structure can be designed at the end of the threaded connection to prevent over-tightening or to provide a physical stop.

The shared connectorcan also be designed as a frictional conical engagement. As shown in, one end of a tree sectionhas an outwardly extending conical section, and an adjacent tree sectionhas a corresponding conical groovethat is precisely matched in shape and taper to the conical section. The conical sectionis typically designed as an inverted cone or a slightly tapered cylinder to facilitate smooth insertion into the conical groove. During assembly, the user simply inserts the conical sectioninto the conical grooveand applies a certain axial force, generating a strong frictional force between the two, thereby achieving a firm connection.

The conical engagement has a significant self-centering characteristic. This means that during insertion, the conical surfaces automatically guide the two tree sectionsinto precise alignment without the need for tedious manual calibration by the user, which is very beneficial for quick assembly and ensuring precise contact of internal electrical connectors. This connection method is simple and fast to operate, requiring no rotational action, and can typically be completed with a simple push-in operation. For disassembly, only a certain axial pulling force is required, sometimes assisted by a slight twist or tap, to easily separate the sections. Another advantage of the conical engagement is the clean and smooth appearance of the joint, with no obvious protrusions, which helps maintain the overall aesthetic and streamlined look of the trunk, making it particularly suitable for products with high aesthetic requirements. The taper angle and surface roughness are key factors affecting the magnitude of the frictional force, and these parameters are optimized to adjust the tightness of the connection and the ease of disassembly. However, it should be noted that the conical engagement relies mainly on friction for fixation; therefore, under certain extreme conditions, such as significant torsional forces or prolonged vibration, there is a possibility of relative rotation. To enhance anti-rotation capability, an anti-slip texture is added to the conical surfaces, or it is combined with other anti-rotation mechanisms such as pins or keyways.

In some embodiments, the shared connectorcan be a snap-fit connector. Referring to, this connection method is achieved through a resilient latching mechanism. A plurality of resilient latching tabsare resiliently disposed on an outer circumferential wall of a connecting end of a first tree section. These latching tabsare typically integrally molded from a resilient material or have a spring mechanism integrated within them, giving them an outward-expanding spring force. A corresponding inner side of an adjacent second tree sectionis provided with a latching grooveformed in its corresponding inner side, which is precisely shaped and sized to correspond with the latching tabs.

During installation, the user inserts the connecting end of the tree sectionwith the latching tabsinto the inner side of the adjacent tree section. As it is inserted, the latching tabsare compressed and retracted inward. When the latching tabsreach the position of the latching groove, they automatically spring outward due to their inherent elasticity or the action of a spring, securely engaging within the latching groove. This is often accompanied by a distinct “click” sound, providing the user with intuitive feedback that the connection is successful. The advantage of this connection method is that assembly and disassembly are extremely fast and convenient, requiring no tools and only simple push-pull operations. Its intuitive feedback (sound and feel) also enhances the user experience. For disassembly, the user typically needs to manually push the latching tabsinward (e.g., by pressing a protruding part on the outside of the tab or a specific release button) before the tree sectionis separated. The shape, number, and material of the latching tabsare designed according to the required connection strength, durability, and operational convenience. For example, multiple small tabs are used to distribute stress and improve service life, or a single large tab can be designed to enhance strength.

In another embodiment, the shared connectorcan be magnetic. Referring to, this connection method utilizes magnetic force to achieve seamless attraction. A first magnetic poleand a second magnetic polewith opposite polarities are disposed on the respective connecting end surfaces of two adjacent tree sections. For example, the first magnetic polecan be designed as a protruding magnetic element with a positive terminalintegrated on its end surface (as shown in). In contrast, the second magnetic poleis designed as a recessed magnetic element with a negative terminalintegrated in its recess (as shown in). When the two tree sectionsare brought close to each other, the strong magnetic attraction between the opposite poles causes the tree sectionsto automatically align and quickly snap together, thereby achieving a firm connection.

The advantages of a magnetic connector include extreme convenience and excellent self-alignment capability. The user does not need to precisely align or apply significant force; the magnetic force automatically guides the two parts into the correct connection, greatly simplifying the assembly process, especially in low-light conditions or with limited operating space. At the same time, since there are no parts subject to mechanical wear, the magnetic connector's durability is excellent, being able to withstand frequent connection and disconnection cycles. For disassembly, the user simply needs to apply a sufficient separation force to pull the two parts apart. Magnetic connectors are particularly suitable for scenarios that require frequent assembly and disassembly or for applications with high demands on connection speed. Additionally, the magnetic force is used to ensure good contact pressure for internal electrical contacts, improving the reliability of electrical conduction. To enhance connection stability, the magnetic elements can also be designed in a ring shape or a multi-point array, providing a more uniform magnetic field distribution and a greater attraction force.

In another embodiment, the shared connectorcan utilize a ball detent mechanism. Referring to, this connection method achieves precise locking through a spring-loaded pin. One or more ball detentsare disposed on the outer or inner wall of one end of a tree section. These ball detentsare typically made of wear-resistant metal or hard plastic and are supported by an internal spring mechanism, allowing them to partially protrude from the surface. An adjacent tree sectionis provided with a corresponding limiting groovethat is precisely shaped and sized to correspond with the ball detent. The limiting grooveis typically designed as a circular hole similar to the ball detentand can be formed in the connecting end surface of the tree section.

During assembly, the user pushes the connecting end of the tree sectionwith the ball detentinto the other tree section. During insertion, the ball detentis compressed by contact with the inner wall of the other section and temporarily retracts into its housing. When the ball detentaligns perfectly with the limiting groove, it immediately pops out due to the spring action and engages with the limiting groove, thereby achieving a secure connection between the two tree sections. This connection method provides clear locking feedback, often accompanied by an audible “click,” and effectively prevents the accidental separation of the tree sections. For disassembly, it is usually necessary to manually push the ball detentback in (e.g., by pressing a small external button or using a special tool), after which the tree sectionis withdrawn. The ball detent mechanism is characterized by its reliable anti-disengagement feature and relatively simple operation while providing good axial positioning. The number and arrangement of the ball detents are adjusted according to the required locking strength and anti-rotation capability.

The shared connectorcan also achieve connection through the engagement of an alignment protrusion and a shoulder. Referring to, this connection method relies on precise mechanical mating and friction. A circumferential or multi-segment alignment protrusionis disposed on the outer side of one end of a tree section. A corresponding shoulderis disposed on the inner side of an adjacent tree section, shaped and sized to precisely match the alignment protrusion.

During assembly, the user inserts the tree sectionwith the protrusioninto the tree sectionwith the shoulder. When the alignment protrusioncontacts the shoulder, a physical stop is formed, preventing over-insertion of the tree sectionby relying on the frictional force between the two tree sectionsto secure the connection. This connection method has the advantages of a simple structure, low manufacturing cost, and good axial positioning. The strength of the connection primarily depends on the coefficient of friction of the materials, the tightness of the fit, and the area of contact. To enhance the stability of the connection, materials with a higher coefficient of friction are selected, or the contact surfaces are roughened. If a stronger fixation is required, this connection method is combined with other locking mechanisms (such as screws or adhesives). Additionally, the shape of the alignment protrusionand the shouldercan be non-circular, providing additional anti-rotation capability.

The shared connectorcan also utilize a connection between a male connectorand a female connector. As shown in, a connecting end of a tree sectionis provided with an outwardly extending male connector, while an adjacent tree sectionhas a corresponding female connectoron its inner side, shaped and sized to precisely match the male connector. The male connectorcan have various shapes, such as circular, quadrilateral, hexagonal, or other custom shapes, to meet different functional requirements and aesthetic designs.

When the male connectoris circular (as shown in), the corresponding female connectoris also circular. This circular design offers excellent rotational freedom, allowing the user to flexibly adjust the relative rotational angle of the tree sectionafter the mechanical connection is made. This is particularly useful in scenarios where fine-tuning the orientation of branches or decorations is necessary to achieve the optimal visual effect.

When the male connectoris quadrilateral (as shown in) or hexagonal (as shown in), the corresponding female connectoris also quadrilateral or hexagonal. This non-circular design can effectively prevent relative rotation between the tree sections, ensuring the structural stability of the assembled tree and maintaining the precise alignment of internal electrical connections. This is particularly important for tree sections with direction-specific electrical connectors or those that require maintaining a fixed visual orientation.

Furthermore, other custom-shaped male connectorsand female connectorscan be used to provide a unique appearance or more complex anti-rotation mechanisms, such as a custom shape with a keyway or anti-slip teeth.

During installation, the user simply inserts the connecting end of the tree sectionwith the male connectorinto the female connector. This connection method is quick and convenient, often relying on a tight fit to provide sufficient frictional force for fixation. To enhance the strength and security of the connection, especially for larger or heavier tree sections, other locking mechanisms can be added at the junction of the male connectorand the female connector, such as an additional snap-fit structure (not shown), locking screws, or locking pins.

In another embodiment, the shared connectorcan achieve connection through the engagement of a through-hole and a positioning pin. As shown in, one or more first through-holesare provided on the connecting end of a tree section. An adjacent tree sectionhas one or more second through-holeson its inner side, which are precisely aligned with the first through-holes.

During assembly, the user inserts the connecting end of the tree sectionwith the first through-holesinto the other tree sectionand rotates or adjusts it until the first through-holesare precisely aligned with the second through-holes. Then, a positioning pinis inserted through the aligned holes, thereby achieving a firm connection between the two tree sections. The positioning pincan be a simple smooth pin secured by a tight fit or friction. More preferably, the positioning pinis threaded. In this case, the first through-holeand the second through-holeshould also be correspondingly threaded to allow the threaded positioning pinto be screwed in, providing extremely strong fastening force, making the connection between the two tree sectionsmore secure and reliable, and effectively preventing relative axial and radial movement. This connection method provides exceptional structural stability and precise positioning, making it particularly suitable for decorative tree sections that must support large loads or require high connection accuracy.

In another embodiment, as shown in, highly integrated electrical connectorsare also disposed between the various tree sectionsto enable electrical power transmission when the end surfaces of the tree sectionscome into contact. These electrical connectors are cleverly designed to complete power transmission simultaneously with the mechanical connection process, thereby eliminating the need for exposed external wires and cumbersome manual wiring common in traditional decorative trees and greatly enhancing the product's safety, aesthetics, and ease of use. For user convenience, the power source can be built-in; for example, a high-capacity battery pack or a power converter can be configured in the baseor in a specific tree section.

The electrical connectorcan be designed in a coaxial or central electrode form. Referring to, one or more protruding male electrodesare disposed on the connecting end surface of a first tree section. A corresponding second tree sectionis provided with a female electrodein a corresponding recessed portion of its inner side, shaped to match the male electrode. The male electrodeand the female electrodeare preferably circular or concentric rings to ensure reliable electrical contact regardless of the relative rotational angle of the tree sectionsupon connection.

When two tree sectionsare connected via their mechanical shared connector, the male electrodeand the female electrodeautomatically align and come into close contact, thereby achieving reliable power transmission. This design is highly integrated and easy to operate; the user only needs to complete the mechanical connection to simultaneously achieve the electrical connection, eliminating the need for additional plugging or unplugging operations. The male electrodeis often designed as a resilient contact point (such as a spring-loaded contact) or a cylindrical structure of a certain height to ensure continuous and reliable contact pressure with the female electrode. The female electrodecan be a simple conductive ring or a conductive groove. The advantage of this electrical connection method is its stable connection, high current transmission efficiency, and resistance to external environmental factors (such as dust and moisture), making it suitable for applications that require high current stability and reliability.

In some embodiments, the electrical connectoris integrated with a threaded mechanical connector. Referring to, in addition to external threadson the circumferential side of the connecting end of a tree section, one or more electrical contactsare also fixed on its end surface. These electrical contactsare typically connected to the positive terminal of the power source and others to the negative terminal. An adjacent tree sectionis provided with an internal threaded grooveon its inner side corresponding to the external threads. A circular electrodeis disposed on the bottom end surface of the internal threaded groove, precisely corresponding to the position of the electrical contacts, for supplying power.

During assembly, the user rotates and screws the tree sectionwith the external threadsand electrical contactsinto the tree section, which has an internal threaded grooveand an circular electrode. As the threads are tightened, the electrical contactscome into close contact with the circular electrode, thereby ensuring reliable power transmission between the tree sections. This design cleverly combines the high mechanical strength of a threaded connection with reliable electrical contact, making it particularly suitable for scenarios that require higher current transmission or maintaining a specific orientation after connection (by tightening the threads to a specific position). The electrical contactsare often designed with a certain elasticity or as a retractable structure, such as spring-loaded contacts, to compensate for manufacturing tolerances and ensure continuous contact pressure, maintaining good conductivity even under long-term use or slight vibration. The circular electrodeprovides a large contact area, further enhancing the reliability of the connection.

The electrical connectorcan also utilize a connection of resilient contact pins (e.g., Pogo Pins) and recesses. Referring to, a plurality of resilient contact pinsare disposed on the connecting end surface of a tree section. These resilient contact pinsare miniature spring-loaded pins containing precision springs, which provide a certain degree of retractability and allow them to maintain constant contact pressure. A corresponding connecting end surface of an adjacent tree sectionis provided with conductive recessesthat precisely correspond in position and number to the resilient contact pins.

During assembly, when the connecting end of the tree sectionwith the resilient contact pinsis inserted into the tree sectionwith the recesses, the resilient contact pinsretract slightly under pressure and make firm contact with the recesses, thereby enabling the transmission of electrical power. The advantages of resilient contact pins include their excellent tolerance compensation capability and reliable contact performance. Due to the action of their internal springs, they can ensure good conductivity even with some degree of connection misalignment or surface unevenness, thus improving the fault tolerance of the assembly. They typically have a long service life, are capable of withstanding tens of thousands or even hundreds of thousands of mating cycles, and have good vibration resistance, making them an ideal choice for frequently mated connections. The recessescan be a gold-plated, nickel-plated, or silver-plated conductive layer to improve conductivity and oxidation resistance, ensuring long-term reliability.

The electrical connectorcan also comprise an elongated conductoron the end surface of a tree section, as well as a corresponding electric brushand a guide grooveon the end surface of another tree section. Referring to, the conductoris typically designed as a strip or a ring to provide a continuous conductive surface. The electric brushis fixed on the end surface of the adjacent tree sectionand is configured to slide within the guide groove. The guide groovecan be a groove or a protrusion that restricts the movement path of the electric brush.

During connection and subsequent use, the electric brushmaintains continuous contact with the conductor, thereby enabling the transmission of electrical power. This design allows the tree sectionto have limited or specific angles of relative rotation after connection while maintaining the continuity of the electrical connection. This is very useful in applications where adjusting the shape or orientation is required. For example, a user can rotate a tree sectionby 180 degrees to change the orientation of branches or decorations without worrying about power interruption or reconnection. The choice of materials for the electric brushand the conductoris crucial; materials with good conductivity, low friction coefficient, and high wear resistance, such as carbon brushes, gold-plated contacts, or alloy brushes, are typically selected to ensure low contact resistance, long service life, and high current transmission efficiency.

In another embodiment, the electrical connectorcan utilize a wireless power transmission method, such as inductive coupling. Referring to, this electrical system includes a transmitterand a receiverdisposed on the opposing end surfaces of two adjacent tree sections. The transmittertypically includes an internal circuit that converts input AC power into high-frequency AC power and generates a varying magnetic field through its built-in coil. According to the laws of electromagnetic induction, this varying magnetic field generated by the transmitterinduces a current in a nearby conductor (i.e., the coil inside the receiver). The coil of the receiverconverts the induced AC into DC power through a built-in rectifier circuit and adjusts it to the appropriate voltage and current through a voltage regulator circuit, thereby supplying power to the LED lights or other electronic components within the tree sectionequipped with the receiver.

The advantages of wireless power transmission are that it can transmit power without any physical contact, greatly improving the reliability, safety, and waterproof/dustproof capabilities of the connection and avoiding problems that traditional metal contacts might face, such as wear, oxidation, corrosion, or short circuits. This makes the assembly process simpler and more intuitive; the user can even achieve power supply without precise alignment (within the range of the magnetic field) while significantly extending the product's service life. This technology is particularly suitable for applications requiring high integration, rapid assembly, and waterproof/dustproof features or in situations where frequent plugging and unplugging are necessary, but physical wear is to be minimized.

The electrical connectorcan also combine a magnetic mechanical connection with a contact-based power supply. Referring again to, a positive terminalcan be integrated on the end surface of the first magnetic pole, and a negative terminalcan be integrated on the end surface of the second magnetic pole.

Through magnetic positioning and attraction, when two tree sectionsapproach each other and connect via magnetic force, the attraction between the first magnetic poleand the second magnetic polenot only ensures mechanical fixation but also causes the positive terminaland the negative terminalto make physical contact, thereby enabling the transmission of electrical power. This design cleverly combines mechanical fixation (via magnetic force) with electrical connection (via electrode contact), further simplifying the interface design and user operation and achieving a convenient “connect-on-contact, power-on-contact” experience. It inherits the convenience and self-aligning features of the magnetic connector and builds upon them to achieve seamless power transmission, resulting in a smoother and more efficient user experience. To ensure reliable electrical contact, the surfaces of the positive terminaland the negative terminalcan be made of highly conductive and corrosion-resistant materials, such as gold-plated or nickel-plated alloys, to guarantee long-term conductive stability and oxidation resistance.

In this embodiment, the decorative tree is not just a simple physical structure. Through its integrated electrical connector, it can achieve rich lighting effects and support smart control, thereby greatly expanding its functionality and user experience, making it an interactive, smart decorative piece.

For example, some tree sectionsare configured with integrated lighting. This design enables users to freely select and combine them according to their personal aesthetics and usage scenarios. For instance, a user can select some tree sections with built-in LED beads to create illuminated areas while choosing other non-illuminated tree sections to create shadows or non-luminous areas, thereby forming a unique lighting layout and brightness gradient that creates a more layered visual effect.

For tree sections with integrated lighting, in some embodiments, the sections may offer multiple light color options. Users can choose according to the desired atmosphere: warm and soft white light for creating a cozy and comfortable environment; cool and bright white light suitable for modern, minimalist settings or situations requiring high brightness; and vibrant and festive colored light (e.g., RGB mode), where users can generate millions of colors by combining red, green, and blue, achieving rich color variations. Additionally, specific single colors are customized to meet special brand displays, themed events, or personal preferences.
