According to the present disclosure, the seatincludes: a baseconfigured to allow the seatto be more stably placed on the ground; a carrierlocated above the baseand configured to carry an infant; a bracketextending upward from the baseand configured to connect to the carrierand suspend the carrierabove the base; and a swing armhaving one end rotatably connected to the carrier, and the other end pivotally or in pivotable manner connected to the bracket, such that the carriermay rotate relative to the swing armand swing relative to the bracket. For example, swing left and right relative to the bracket. The baseand the bracketof the seatmay be integrally or separately configured. According to the present embodiment, the baseis configured as a rod member, which forms an enclosed space. And in other embodiments, the basemay also be formed by a continuous plate. When the carrieris stationary relative to the base, a central area of the carrieris approximately located directly above the baseand its enclosed space, to provide stable support for the carrierand prevent the carrierfrom tipping over. The bracketextends upward from a rear side edge of the base, and wheelsare provided at a lower rear side of the bracket. When the seatis placed on a horizontal plane as shown in, the wheelsdo not contact the ground. When it is necessary to change the usage location, the seatmay be tilted backward so that the wheelsmay contact the ground and roll, facilitating transportation. According to the present embodiment, the wheelsare provided in two, respectively located on opposite sides of the bracket. Alternatively, the wheelsmay also be disposed on the base.

According to the present disclosure, to facilitate the infant's seating and to allow the infant to be placed in different swing directions, the carrierof the seatis configured to rotate relative to the base, the bracket, and the swing arm. According to the present disclosure, the carrierincludes a connecting base, an underframe, an armrest frame, two connecting frames, a support rod, and a handle. The connecting baseis configured to connect to the swing arm. The underframeis connected to the connecting base. And the underframeis configured in a frame shape. Specifically, the connecting baseis connected to two opposite sides of the underframe, for example, the underframeforms a generally rectangular frame and is connected to the longer opposite sides of the underframe. And the underframemay be directly supported on the ground after the carrieris removed from the swing arm. The underframemay be configured with upwardly curved sides (see), which is advantageous for independently functioning as a cradle on the ground. The armrest frameis located above the underframeand also configured in a frame shape for fixing an upper periphery of a seat fabric supporting the infant. The two connecting framesare spaced apart and respectively connected to the underframeand the armrest frame. And the two connecting framesconnected to the connecting base. For example, the two connecting framesare respectively connected to the two ends of the connecting baseat two connection points of the two connecting framesand the underframe. The support rodis located between the armrest frameand the underframe, with both ends respectively connected to the two connecting framesand configured in a U-shape. For example, the two ends of the support rodare respectively connected to the two connection points of the two connecting framesand the armrest frame. And the ends of the support rodconnected to the connecting framesare higher than the other parts of the support rod. The support rodextends forward toward an end of the armrest framewithout exceeding the end of the armrest frame. And the support rodis configured to extend downward between the two ends of the armrest frameto support a bottom of an inner lining material carrying the infant. The handleis connected to the armrest frameand located above the armrest frame. The two connection points of the two ends of the handleto the armrest framecorrespond to the two connection points of the armrest frameto the two connecting frames, which can allow the user to carry the carrierby using the handle.

According to the present disclosure, the seatis provided with a carrier mounting partat an end of the swing armconnected to the connecting base. The carrier mounting partincludes a rotating baseand a fixed base, which may rotate relative to each other around an axis X. The fixed baseis fixedly connected to the swing arm, and the rotating baseis detachably connected to the carrierand cannot rotate relative to the carrier, so that an orientation of the carrierrelative to the swing armmay be adjusted by rotating the rotating baserelative to the fixed base. Specifically, the connecting baseis detachably connected to the rotating baseof the carrier mounting part. For example, the connecting basemay be sleeved over an outside of the rotating basefrom above. The specific implementation of the rotating basewill be explained in detail based on the subsequent drawings.

shows a side view of the seataccording to the present disclosure. In, it can be seen that the fixed baseof the carrier mounting partis fixedly connected to an end of the swing arm, while the rotating baseof the carrier mounting partis connected to the connecting baseof the carrier. The connecting baseis further connected to the underframeand the connecting frame, and the connecting frameis connected to the support rod, the armrest frame, and the handle. As a result, the weight of the carrierand the infant is stably supported by the swing armthrough the carrier mounting part. And the carrier mounting partis located directly above the enclosed space formed by the basein a vertical direction, to prevent the seatfrom tipping over. The side view of the underframeis curved, with the lowest part of the curve located at the middle of the underframeand aligned vertically with the connecting base. When the carrieris supported on the ground, the lowest part of the curve contacts the ground. If an external force is applied to the carrierat this time, the carriermay swing around the lowest point of the curve to soothe or assist the infant in falling asleep. The swing armis designed in a generally L-shape, and the other end of the swing armis pivotally connected to an upper part of the bracket. According to the present embodiment, the swing armis provided with a pivot partfor pivoting with the bracket. The pivot partinmay pivot relative to the bracketin a direction perpendicular to a paper plane. The rest of the swing armis inserted into the pivot partfrom below at an angle and is fixedly connected to the pivot partusing a connector, such as a bolt or pin, so as to swing together with the pivot partrelative to the bracket.

From, it can also be seen that the wheelsdo not contact the ground when the seatis placed flat on the ground, which can advantageously prevent the seatfrom being inadvertently moved. Only when the seatis tilted backward, the wheelsmay contact the ground and roll.

shows a bottom cross-sectional view of the seataccording to the present disclosure, taken along a section line A-A in. From, it can be seen that the carrier mounting partis located at a center of the underframeand the armrest frameof the carrier. The fixed baseof the carrier mounting partis located at the middle of the connecting base, which may be molded from hard materials such as plastic.

shows a perspective view of the seataccording to the present disclosure after the carrieris removed. The swing armto swing left and right relative to the bracketmanually or electrically when the seatis in use. When an electric method is used, a motor may be disposed in the pivot partto drive the swing armto swing relative to the bracket.

In, it can be seen that the rotating baseincludes a connecting protrusionat its center. The connecting protrusionis configured to be inserted into the connecting slotof the connecting baseshown inand is shaped in a cross shape corresponding to the connecting slot. According to the present embodiment, the connecting protrusionis composed of four protrusions spaced apart circumferentially around the axis X. Advantageously, at least one of the four protrusions may differ in shape from the others, and at least one of the four slot holes of the connecting slotis configured to correspond to the at least one protrusion, while the remaining slot holes are configured to match the other protrusions. This arrangement can ensure that the rotating baseand the connecting baseof the carriermay only be assembled in a specific direction, thereby avoiding assembly errors. Additionally, since outer edges of both the connecting protrusionand the connecting slotare non-circular, the connecting basemay not rotate relative to the rotating baseafter the connecting protrusionis inserted into the connecting slot, that is, the carriermay not rotate relative to the rotating base, and both may only rotate together relative to the fixed base.

The connecting shaftis inserted from above into the fixing partof the rotating base, and a head of the connecting shaftis engaged with a boss inside the fixing partof the rotating base. The other end of the connecting shaftpasses through the fixing partof the rotating baseand a perforation in the lower connecting part, extends below the fixed base, so that the rotating basemay rotate relative to the fixed basearound the axis X. The rotating baseis provided with spaced side wallsandalong a radial direction perpendicular to the axis X. The side wallsandextend along the circumferential direction around the axis X, respectively. According to this embodiment, The rotating baseis provided with two adjacent outer side wallsand two adjacent inner side wallsare spaced apart in the radial direction perpendicular to the axis X. That is, the number of the outer side walland the number of inner side wallare respectively set to two, as shown in. The positioning partof the fixed baseis located between the outer side walland the inner side wall, specifically the positioning partbetween the outer side walllocated radial inside of the two adjacent outer side wallsand the inner side walllocated radial outside of the two inner side walls. The positioning partof the fixed basemay abut against the outer side wallor the inner side wall, or both. According to this embodiment, along an extending direction of the lower connecting part, the positioning partis arranged opposite to the lower connecting partand has a gap, which advantageously allows the positioning partto partially deform elastically. Alternatively, the positioning partmay abut against the lower connecting part, i.e., against the end of the lower connecting part. In this case, it can provide greater support to the positioning part.

According to this embodiment, the reinforcement partof the lower connecting partis, for example, a hollow tube and is provided in two, intersecting perpendicularly with the extending direction of the lower connecting partand spaced apart from the axis X, thereby enhancing the stability of the connection between the lower connecting partand the fixed base.

The rotating basemay be molded from plastic or made in other ways, and an interior of the connecting protrusionmay be molded as a hollow portion, thereby saving the materials. The center of the hollow portion is molded with a fixing partfor inserting the connecting shaftshown in.

According to this embodiment, the outer side wallis formed around the axis X and extends downward along the axis X. The outer side wallis configured to abut against the fixed basein the radial direction perpendicular to the axis X to prevent radial movement of the rotating baserelative to the fixed base, which could cause misalignment of two along the radial direction perpendicular to the axis X. According to the present embodiment, one of the two outer side wallsis located in a radial inside of the other one of the two outer side walls. The outer side wall located in the radial outside is arranged along an outer periphery of the rotating base, and the two outer side wallsare spaced apart to form a first buffer partA. At least one first connecting ribA connects the two outer side walls. A plurality of first connecting ribsA are evenly spaced circumferentially around the axis X, enhancing the connection between the two outer side wallswhile reducing material usage compared to a continuous connection between the two outer side walls.

According to this embodiment, the inner side wallis formed around the axis X and extends downward along the axis X. The inner side wallis located inside the outer side walland radially spaced apart from the outer side wall. According to the present embodiment, one of the two inner side wallsis located at a radial inside of the other one of the two inner side walls. The inner side walllocated in the radial inside is approximately aligned vertically with the outer periphery of the connecting protrusion, which allows the rotational force on the connecting protrusionto be better transmitted to the two inner side walls. A second buffer partB is also formed between the two inner side walls, and at least one second connecting ribB connects the two side walls. A plurality of second connecting ribsB are evenly spaced circumferentially around the axis X, enhancing the connection between the two inner side wallswhile reducing the material usage compared to the continuous connection between the two inner side walls. In other embodiments, the rotating basemay have only one inner side wall, and the inner side wallis approximately aligned vertically with the outer periphery of the connecting protrusionor located at a radial outside of the outer periphery of the connecting protrusion.

According to the present disclosure, at least two, preferably four, engaging partsare disposed on the inner side wallin the radial outside of the two inner side walls. The four engaging partsare evenly spaced on the outer layer of the inner side walland are configured to cooperate with the positioning partprovided on the fixed base(see) to position the rotating baserelative to the fixed basein four different positions, thereby positioning the carrierrelative to the swing arm, the bracket, and the basein four different positions, as shown in. According to the present embodiment, the engaging partsare configured as positioning recesses. Each of the positioning recessesincluding two elastic protrusionsprotruding outward from the inner side wallin the radial outside of the two inner side wallsin the radial direction perpendicular to the axis X. Specifically, the elastic protrusionsare formed by locally outward curving of the outer side wall, and the edges of the elastic protrusionsare curved. Alternatively, the elastic protrusionsmay be formed in other ways. The two elastic protrusionsand the inner side wallin the radial outside of the two inner side wallsbetween the two elastic protrusionsform the positioning recess, which cooperates with the positioning partprovided on the fixed base(see). For example, the positioning partis engaged in the positioning recessbetween the two elastic protrusions. According to the present disclosure, the elastic protrusionsmay be omitted, and the inner side wallin the radial outside of the two inner side wallsmay be inwardly curved in the radial direction to form the positioning recessof the present disclosure, but the present disclosure is not limited thereto. Advantageously, the engaging partsare arranged opposite to the second connecting ribsB in the radial direction perpendicular to the axis X to enhance the strength of the positioning recess. Specifically, the second connecting ribsB are arranged radially opposite to the inner side wallin the radial outside of the two inner side wallsbetween the two elastic protrusionsof the corresponding positioning recess, thereby enhancing the engagement between the positioning recessand the positioning parton the fixed base.

Additionally, the engaging partsmay be disposed on the outer side wallin the radial inside of the two outer side walls. Specifically, the engaging partsare configured as the positioning recesses, and each of the positioning recessesincludes two elastic protrusionsprotruding inward from the outer side wallin the radial inside of the two outer side wallsin the radial direction perpendicular to the axis X.

shows a top perspective view of the swing armand the fixed baseaccording to the present disclosure. In, a structure of the lower connecting partof the swing armmay be seen. The lower connecting partis provided with at least one, preferably two or more, reinforcement parts. The reinforcement partsare, for example, rods or tubes and extend transversely through the lower connecting partin a direction perpendicular to the extending direction of the lower connecting part. The reinforcement partsare spaced apart from the axis X, specifically located on both sides of the axis X along the extending direction of the lower connecting part. The reinforcement partsand the lower connecting partare provided with a plurality of perforations for fixing the lower connecting partand the reinforcement partsto the fixed baseof the carrier mounting partrespectively, thereby increasing the number of fixed points between the swing armand the fixed baseand achieving a more stable connection between the two.also shows the connecting shaftfor connecting the fixed baseand the rotating base.

According to the present disclosure, the fixed baseis provided with one positioning part, for cooperating with the engaging partor the positioning recessprovided on the rotating baseshown inin the circumferential direction around the axis X, to limit the rotation of the rotating baserelative to the fixed basearound the axis X. This can ensure that the rotating baseand the fixed baseare relatively fixed, thereby fixing the carrierrelative to the swing armto position the carrier. According to the present disclosure, the positioning partis configured as a positioning protrusionprotruding upward from the bottom of the fixed base. The positioning protrusionmay be solid or hollow. As shown in, the positioning protrusionis configured as a hollow elliptical structure with a transverse ribinside to enhance a strength of the positioning protrusion. The positioning protrusionis disposed opposite to the lower connecting partalong the extending direction of the lower connecting partof the swing arm, or may abut against the lower connecting part, so that the lower connecting partcan provide stable support to the positioning protrusion. In other embodiments, multiple positioning protrusionsmay be evenly spaced circumferentially around the axis X, but the present disclosure is not limited thereto.

shows a side view and a cross-sectional view of the swing armand the carrier mounting partaccording to the present disclosure. The upper view inis a cross-sectional view taken along a section line D-D in the lower view, allowing a portion of the rotating baseand the fixed baseto be seen.

The positioning protrusionprotruding upward from the fixed baseis located between the outer side wallin the radial inside of the two outer side wallsand the inner side wallin the radial outside of the two inner side walls, and abuts against the outer side walland the inner side wall. The positioning protrusionis currently engaged in a positioning recessof the rotating baseand abuts against the elastic protrusionsat both ends of the positioning recessin the circumferential direction around the axis X, to limit the rotation of the positioning protrusionrelative to the corresponding positioning recess. When the orientation of the carrieris adjusted, the rotating baserotates relative to the fixed baseas the user turns the carrier. The elastic protrusionon a trailing side of the rotation direction deforms radially into the corresponding second buffer partB due to the resistance of the positioning protrusion, to cause the positioning protrusionto disengage from the positioning recess. As the rotating basecontinues to rotate, for example, byas shown in, the positioning protrusionre-engages with another positioning recess, to change the orientation of the carrierby 90 degrees and positioning the carrier. In this manner, the carriermay be positioned in the four orientations shown inrespectively.

Alternatively, the positioning protrusionmay be disposed on the rotating base, and the positioning recessmay be disposed on the fixed base, i.e., the engaging partis configured as the positioning protrusion, and the positioning partis configured as the positioning recess. The fixed baseis provided with the inner side wallor the outer side wallforming the positioning recess.

Alternatively, at least two, preferably four, positioning protrusionsmay be disposed on the fixed base, spaced apart circumferentially around the axis X, while the rotating baseis provided with, for example, only one positioning recess. The positioning recesscooperates with different positioning protrusionsto position the carrierat different locations.

By providing the engaging partand the positioning part, such as the positioning protrusionand the positioning recess, cooperated with each other on the fixed baseand the rotating base, respectively, so that the rotational positioning of the carriercan be achieved with few parts, a simple structure, and convenient operation.
