Compared with the prior art, the present disclosure has at least the following beneficial effects:

In the present disclosure, when the unlocking member is pressed to unlock the first locking member, the first rod member and the second rod member can rotate relative to each other, allowing the upper enclosure frame to be folded. During the folding process, the first rod member and the second rod member drive the second locking member to unlock, enabling the supporting legs to rotate relative to the upper enclosure frame and fold towards the upper enclosure frame, thus completing the overall folding of the bed frame.

The folding action is simple, and the bed frame is compact after folding, occupies little space, and is easy to store and carry.

In the present disclosure, when the bed frame is unfolded, the four supporting legs are positioned at the four corners of the upper enclosure frame, with each supporting leg inclined outwardly relative to the upper enclosure frame at an angle between 8° and 12°. This ensures the stability of the bed frame when unfolded and guarantees that the height of the bed frame is sufficient.

In the present disclosure, the lengths of the first rod member and the second rod member in the first enclosure rod are equal, and are also equal to the length of the second enclosure rod. After the bed frame is folded, the length of the bed frame equals to the length of the second enclosure rod. The four supporting legs are folded toward the upper enclosure frame, with two supporting legs stacked on top of the other two, resulting in a compact overall volume.

In this embodiment, as shown into, a foldable bed frame is optimally applied to a bed for children, and the bed for children folds as the bed frame folds. When the foldable bed frame is applied to a bed for children, the bed for children mainly includes the foldable bed frame and a cloth cover (not shown in the figures), and the cloth cover is arranged on the foldable bed frame, and can be unfolded as the bed frame is unfolded, and folded as the bed frame is folded. The foldable bed frame has an unfolded state and a folded state. When used, the bed frame is switched to the unfolded state (as shown in), and when not used, the bed frame is switched to the folded state (as shown into), thereby reducing the space occupied by the bed frame and ensuring convenient storage and carrying.

In this embodiment, the foldable bed frame mainly includes an upper enclosure frameand a plurality of supporting legsrotatably connected to the upper enclosure frame. When the bed frame is switched from the unfolded state to the folded state: the two first enclosure rodsrotate and fold inwardly, and the two second enclosure rodsmove closer to each other; a plurality of the supporting legsrotate and fold, and the supporting ends of the plurality of supporting legsmove closer to the upper enclosure frame.

As shown into, the upper enclosure frameincludes two first enclosure rodsand two second enclosure rodsarranged opposite to each other. The length of the first enclosure rodis greater than that of the second enclosure rod. During the folding process, the first enclosure rodcan be folded in the center. To ensure that the space occupied after folding is small, the length of the first enclosure rodis approximately twice that of the second enclosure rod. Two ends of one of the first enclosure rodsare rotatably connected to one end of the two second enclosure rods, and two ends of the other first enclosure rodare rotatably connected to the other end of the two second enclosure rods. Therefore, the two first enclosure rodsand the two second enclosure rodsare connected end to end to form a rectangular frame structure, namely, an upper enclosure frame. the first enclosure rodcomprises a first rod member, a second rod member, a first locking member, and an unlocking member, the first rod memberand the second rod memberare rotatably connected, the first locking memberis disposed between the first rod memberand the second rod member, and is able to lock the first rod memberand the second rod member; the unlocking memberis able to unlock the first locking member. After the first locking memberis unlocked, the first rod memberand the second rod membercan rotate relative to each other to facilitate folding.

One end of the plurality of supporting legsis rotatably connected to the upper enclosure frame, specifically, the upper end of the supporting legis provided with a connecting joint, and the supporting legis rotatably connected to the upper enclosure framethrough the connecting joint at the end thereof. The other ends of the plurality of supporting legsare supporting ends, i.e., the lower ends of the plurality of supporting legsare supporting ends, and the plurality of supporting ends can be supported on the ground to support the entire bed frame, i.e., to support the bed for children. The supporting ends of the supporting legscan be provided with foot pads to increase the friction with the ground to ensure reliable support and no slipping. The foot pads are provided with through grooves for the connecting cloth belts to pass through, so as to facilitate the fixing of the cloth cover in the bed for children. A second locking memberis arranged between the supporting legand the upper enclosure frame, and the second locking memberis able to lock the supporting leg. When the second locking memberlocks the supporting leg, the supporting legcannot be folded, so as to ensure the supporting stability of the supporting legwhen the bed frame is unfolded for use. During use, when a user drives the unlocking memberto unlock the first locking member, the first rod memberand the second rod membercan rotate inwardly and fold, and during the folding process, the first rod memberand the second rod membercan drive the second locking memberto unlock so as to fold the supporting leg. After the upper enclosure frameand the plurality of supporting legsare folded, the entire bed frame is folded.

In actual use, after the first locking memberlocks the first rod memberand the second rod member, the first rod memberand the second rod membercannot be folded, thereby ensuring the structural stability when unfolded. Only when the unlocking memberunlocks the first locking member, the first rod memberand the second rod membercan be relatively folded.

In this embodiment, for the foldable bed frame, when the unlocking memberis pressed to unlock the first locking member, the first rod memberand the second rod membercan rotate relative to each other, allowing the upper enclosure frameto be folded. During the folding process, the first rod memberand the second rod memberdrive the second locking memberto unlock, enabling the supporting legsto rotate relative to the upper enclosure frameand fold towards the upper enclosure frame, thus completing the overall folding of the bed frame. In the folding process, only the unlocking memberneeds to be pressed to achieve one-button folding, without the need of multiple unlocking actions. The folding action is simple, and the bed frame is compact after folding, occupies little space, and is easy to store and carry.

It should be explained that both ends of the first rod memberare provided with connecting joints, both ends of the second rod memberare provided with connecting joints, and both ends of the second enclosure rodare also provided with connecting joints. Each enclosure rod is rotatably connected to each rod member through the connecting joint at the ends thereof. The end (i.e., the upper end) of the supporting legclose to the upper enclosure frameis also provided with a connecting joint. All the connecting joints are made of plastic and can be injection molded. The specific structure of each connecting joint can be designed according to the actual needs of the user. Compared with other materials, the connecting joints made of plastic can be conveniently designed with corresponding structural features thereon, and are integrally injection-molded conveniently.

Specifically, the connecting joints at both ends of the second enclosure rodare configured as first connecting joints, and the connecting joint at the end of the first rod memberclose to the second enclosure rodand the connecting joint at the end of the second rod memberclose to the second enclosure rodare configured as second connecting joints. In this embodiment, the first connecting jointsis configured as four, and the number of the second connecting jointsis also configured as four. The first connecting jointis provided with multiple layers of first connecting piecesA arranged in a spaced manner, and the multiple layers of first connecting piecesA are arranged in parallel. The second connecting jointis provided with multiple layers of second connecting piecesA arranged in a spaced manner, and the multiple layers of second connecting piecesA are arranged in parallel. The multiple layers of first connecting piecesA and the multiple layers of second connecting piecesA are hinged to realize the hinge connection between the second enclosure rodand the first rod memberor between the second enclosure rodand the second rod member.

Among them, a second connecting pieceA is sandwiched between two adjacent layers of the first connecting piecesA, and a first connecting pieceA is sandwiched between two adjacent layers of the second connecting piecesA. In this embodiment, as shown in the figures, there are three layers of the first connecting piecesA and two layers of the second connecting piecesA; the three layers of the first connecting piecesA and the two layers of the second connecting piecesA are interlaced and hinged to ensure the hinge stability. Furthermore, when relative rotation occurs between the second enclosure rodand the first enclosure rod, it is ensured that the relative rotation between the first enclosure rodand the second enclosure rodis basically only allowed to occur in the same plane, ensuring smooth relative rotation.

In this embodiment, a first locking grooveis formed on each supporting leg, and the first locking grooveis located at the connecting joint at the upper end of the supporting leg. When the second locking memberis engaged with the first locking groove, the supporting legis locked, and the supporting legcannot be rotated relative to the upper enclosure frameat this time, that is, the supporting legcannot be rotated and folded. When the second locking memberis disengaged from the first locking groove, the supporting legis unlocked, and the supporting legcan be rotated and folded relative to the upper enclosure frameafter being unlocked.

When the bed frame is in the unfolded state, the upper enclosure frameis rectangular, and a supporting legis disposed at each of the four corners of the upper enclosure frame, that is, a total of four supporting legsare provided on the bed frame. At this state, the four supporting legsare tilted outward relative to the upper enclosure frame, and the tilt angle of the supporting legsis between 8° and 12°, and the optimal angle is 9°, which not only ensures the stability of the bed frame and prevents from tipping over when being unfolded, but also ensures sufficient height of the bed frame. The supporting legneeds not to be made very long.

As shown into, when the bed frame is switched from the unfolded state to the folded state, all four supporting legsare rotated and folded toward the upper enclosure frame. After the folding is completed, two of the supporting legsare stacked on the other two supporting legs. After the four supporting legsare folded, there is no outward protrusion and basically no space outside the upper enclosure frameis occupied, thereby ensuring that the volume of the bed frame after being folded is small.

In this embodiment, the first rod member, the second rod memberand the second enclosure rodare of equal length, and the length of the supporting legis less than or equal to the length of the first rod member, the second rod memberand the second enclosure rod, preferably, the length of the supporting legis basically equal to the length of the first rod member, the second rod memberand the second enclosure rod. The length of the bed frame, when being folded, is equal to the length of the second enclosure rod, the width of the bed frame is the sum of the widths of the two first connecting joints, the sum of the height of the first connecting jointand the height of the connecting joint at the top of the supporting leg, that is, substantially equal to the height of the bed frame after being folded.

As shown inin conjunction with, the second locking memberis connected to the first enclosure rodvia a pull wire, one end of the pull wireis connected to the second locking member, and the other end of the pull wireis connected to the second connecting jointat the end of the second rod memberin the first enclosure rod, and a channel for the pull wireto pass through is provided on a layer of second connecting piecesA of the second connecting joint. Similarly, a channel for the pull wireto pass through is also provided inside the first connecting joint. When the first enclosure rodrotates relative to the second enclosure rod, the first enclosure rodcan pull the second locking memberthrough the pull wireto unlock the second locking member. Furthermore, a first springis disposed between each supporting legand the upper enclosure frame; one end of the first springabuts against the second locking member, and the other end of the first springabuts against the upper enclosure frame. The elastic force of the first springenables the second locking memberto have a tendency to move in its locking direction. Under the action of the first spring, the second locking memberwill not be separated from the first locking groovewhen in the locked state, thereby ensuring reliable locking. That is, when the bed frame is in the unfolded state, the supporting legis locked by the second locking member, and there will be no mis-locking situation, thereby ensuring reliable support of the supporting leg. When the first enclosure rodpulls the second locking membervia the pull wireto unlock the second locking member, the first springis compressed. When the bed frame is switched to the unfolded state, the second locking membercan be automatically locked into the first locking grooveunder the action of the first spring, to achieve automatic locking and facilitating the use.

Preferably, a receiving grooveis formed on the second locking member, and the first springis located in the receiving groove, that is, the first springdoes not need to occupy additional mounting space and has a compact structure. On the second locking member, a boss protrudes into the receiving groove, and one end of the first springis sleeved on the boss to ensure that the first springwill not be separated from the second locking memberduring the locking and unlocking of the second locking member.

Further, specifically, a second locking grooveA is formed on the second rod member, and the first locking memberis able to be locked into the second locking grooveA to lock the first rod memberand the second rod member. At this time, part of the first locking memberis in the first rod member, and the other part is in the second rod member, so that the first rod memberand the second rod membercannot rotate relative to each other, that is, the first rod memberis also correspondingly provided with a groove adapted to the first locking member, the shape of the groove is the same as the shape of the second locking grooveA; both the groove and the second locking grooveA can be inserted into the first locking member. The unlocking memberis able to push the first locking membersuch that the first locking memberis disengaged from the second locking grooveA, thereby unlocking the first rod memberand the second rod member, and the first rod memberand the second rod membercan be rotated and folded. A second springis provided between the first rod memberand the first locking member, one end of the second springabuts against the first locking member, and the other end of the second springabuts against the first rod member; the elastic force of the second springenables the first locking memberto have a tendency to move in its locking direction; when the unlocking memberdrives the first locking memberto unlock, the second springis compressed. Similarly, the arrangement of the second springcan ensure the structural stability of the first locking memberwhen being locked, so that the first locking memberwill not be accidentally separated from the second locking grooveA, and when the bed frame is unfolded, the force of the second springenables the first locking memberto be automatically locked into the second locking grooveA, which is convenient to use.
