DETAILED DESCRIPTION

[0043] In order to make the above objectives, characteristics and advantages of the present application more apparent, more comprehensible, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0044] An embodiment of the present application provides a foldable baby crib, which can be switched between an unfolded state and a folded state. In the folded state, the foldable baby crib has a small volume, which is conducive to reducing the occupied space and facilitating carrying and storage. In the unfolded state, the foldable baby crib can provide a play or sleep space for infants.

[0045] In combination Figure 1 and Figure 2 The foldable baby crib comprises side frames 10, a surrounding rod assembly 20, a support assembly 30, a lock assembly 40 and a linkage unlocking mechanism 50.

[0046] The side frames 10 are provided in two, and for the purpose of description, the two side frames 10 are respectively referred to as "first side frame 10a" and "second side frame 10b". The first side frame 10a and the second side frame 10b are arranged in a first direction. The first direction is represented by S1.

[0047] The first side frame 10a and the second side frame 10b each comprise a first support piece 11, a second support piece 12, a guardrail 13 and a reinforcing piece 14.

[0048] The first support piece 11 and the second support piece 12 are arranged in a second direction, and the first direction is perpendicular to the second direction. The second direction is represented by S2.

[0049] The two ends of the guardrail 13 are respectively connected to the upper part of the first support piece 11 and the upper part of the second support piece 12.

[0050] The two ends of the reinforcing piece 14 are respectively connected to the lower part of the first support piece 11 and the lower part of the second support piece 12.

[0051] Optionally, the first support piece 11, the second support piece 12, the guardrail 13 and the reinforcing piece 14 are connected to form an integrated rectangular frame. In this way, it is convenient for production and processing, and it is also convenient for assembling the foldable baby crib, thereby improving the assembly efficiency of the foldable baby crib.

[0052] In another embodiment, the first support piece 11 is detachably connected with the guardrail 13 and the reinforcing piece 14, and the second support piece 12 is detachably connected with the guardrail 13 and the reinforcing piece 14. In this way, the first side frame 10a and the second side frame 10b can be detached, which is conducive to reducing the packaging volume of the foldable baby crib and reducing transportation costs.

[0053] The connection manner of each structure in the first side frame 10a and the second side frame 10b and the structure of the surrounding rod assembly 20 are not limited herein. As long as the first side frame 10a and the second side frame 10b can be close to each other during the folding of the foldable baby crib to meet the folding needs of the foldable baby crib.

[0054] Continuing to combine Figure 1 and Figure 2 The surrounding rod assembly 20 is provided with two, and both of the surrounding rod assemblies 20 are arranged between the first side frame 10a and the second side frame 10b and are spaced apart in the second direction. It can be understood that both ends of the two surrounding rod assemblies 20 in the second direction are connected between the first side frame 10a and the second side frame 10b.

[0055] Optionally, the surrounding rod assembly 20 is detachably connected with the first side frame 10a and the second side frame 10b. In this way, the foldable baby crib can be disassembled, which is beneficial to reducing the packaging volume of the foldable baby crib and reducing transportation costs.

[0056] Continuing to combine Figure 1 Both of the surrounding rod assemblies 20 include a first rod 21 and a second rod 22. The first end of the first rod 21 is rotatably connected with the first side frame 10a, the first end of the second rod 22 is rotatably connected with the second side frame 10b, and the second end of the first rod 21 is rotatably connected with the second end of the second rod 22.

[0057] Optionally, the first rod 21 and the second rod 22 are hollow tubes. For example, the first rod 21 and the second rod 22 are both hollow circular tubes. In this way, the weight of the foldable baby crib can be reduced, and the cost can also be reduced. Of course, in another embodiment, the first rod 21 and the second rod 22 can also be solid rods.

[0058] The support assembly 30 is provided with two, and both of the support assemblies 30 are arranged between the first side frame 10a and the second side frame 10b and are spaced apart in the second direction. One end of the support assembly 30 is connected with the first side frame 10a, and the other end of the support assembly 30 is connected with the second side frame 10b.

[0059] Optionally, the support assembly 30 is detachably connected with the first side frame 10a and the second side frame 10b. In this way, the foldable baby crib can be disassembled, which is beneficial to reducing the packaging volume of the foldable baby crib and reducing transportation costs.

[0060] Combining Figure 3The support assembly 30 comprises a third rod 31, a fourth rod 32 and a folding joint 33. The first end of the third rod 31 is rotatably connected with the first side frame 10a. The first end of the fourth rod 32 is rotatably connected with the second side frame 10b. The second end of the third rod 31 is rotatably connected with the second end of the fourth rod 32 through the folding joint 33.

[0061] Optionally, the third rod 31 and the fourth rod 32 are hollow tubes. For example, the third rod 31 and the fourth rod 32 are both hollow circular tubes. In this way, the weight of the foldable baby bed can be reduced, and the cost can also be reduced. Of course, in another embodiment, the third rod 31 and the fourth rod 32 can also be solid rods.

[0062] It should be noted that for the foldable baby bed which has a cuboid frame in the unfolded state, the parts connected by the surrounding rod assembly 20 and the support assembly 30 can share structural members. For example, the reinforcing member 14 in the surrounding rod assembly 20 can also be used as a part of the support assembly 30.

[0063] In some embodiments, the reinforcing member 14 can also be removed from the side frame 10 and used as a part of the support assembly 30. When the support assembly 30 is installed between the first side frame 10a and the second side frame 10b, the reinforcing member 14 is located between the first support 11 and the second support 12.

[0064] In this embodiment, the two ends of the support assembly 30 can each be provided with a reinforcing member 14, and the first side frame 10a and the second side frame 10b can be installed through the corresponding reinforcing member 14 of the corresponding side.

[0065] Further, the installation height of the reinforcing member 14 at the two ends of the support assembly 30 on the first side frame 10a and the second side frame 10b can be adjusted, so that the installation height of the support assembly 30 can be adjusted.

[0066] It should be noted that the upward pulling and downward placing of the support assembly 30 enable the foldable baby bed to realize different functions. For example, when the foldable baby bed is placed beside an adult bed, the support assembly 30 is pulled up so that the adult and the baby are at substantially the same height, which facilitates the adult to take care of the baby, and at this time the foldable baby bed can realize the function of providing a resting place. For another example, the support assembly 30 is placed down, so that the baby playing in the foldable baby bed will not fall out, and at this time the foldable baby bed can realize the function of providing a playing place, i.e. a playpen.

[0067] In order to prevent the foldable baby bed from being mistakenly folded during use, the foldable baby bed of the present application also has a locking function for locking the unfolded state and an unlocking function for unlocking.

[0068] For the convenience of understanding, the unfolded and locked state of the foldable baby crib is referred to as "locked state", and the state of the foldable baby crib after being unlocked for folding is referred to as "unlocked state".

[0069] Specifically, when the foldable baby crib is in the locked state, the surrounding rod assembly 20 cannot be folded due to being locked, that is, the rotation freedom between the first rod member 21 and the second rod member 22 is locked, so that the first rod member 21 and the second rod member 22 will not rotate relative to each other to fold.

[0070] In combination Figure 2 and Figure 3 When the foldable baby crib is in the unfolded state, the lock assembly 40 is used to limit the relative rotation of the first rod member 21 and the second rod member 22.

[0071] It should be noted here that since the locking and unlocking of the foldable baby crib are both for the locking or unlocking of the corresponding lock assembly when the foldable baby crib is in the unfolded state, the locking of the foldable baby crib can be understood as the lock assembly 40 being in the locked state; accordingly, the unlocking of the foldable baby crib can be understood as the lock assembly 40 being in the unlocked state.

[0072] In combination Figure 1 and Figure 2 The lock assembly 40 is arranged at the second end of the first rod member 21 and the second end of the second rod member 22, and the first rod member 21 is rotatably connected to the second rod member 22 through the lock assembly 40.

[0073] In combination Figure 1 When the lock assembly 40 is in the unlocked state, the first rod member 21 and the second rod member 22 can both rotate relative to the side frame 10, so that the foldable baby crib can be folded and closed.

[0074] In combination Figure 2 When the lock assembly 40 is in the locked state, the first rod member 21 and the second rod member 22 are coaxially arranged, and the first rod member 21 and the second rod member 22 are both fixed relative to the side frame 10.

[0075] In combination Figure 2 The lock assembly 40 is provided with two. One of the lock assemblies 40 is arranged at the second end of one of the first rod members 21 and the second end of the corresponding second rod member 22, and the other lock assembly 40 is arranged at the second end of the other first rod member 21 and the second end of the corresponding second rod member 22.

[0076] In combination Figure 4 and Figure 5The lock assembly 40 comprises a lock tongue 41, a lock plug 42 and a housing 43. The lock tongue 41 is movably arranged at the second end of the first rod member 21, and the lock plug 42 is arranged at the second end of the second rod member 22. In the locked state, the lock plug 42 overlaps the lock tongue 41, and restricts the rotation of the first rod member 21 and the second rod member 22 relative to the housing 43, so as to keep the surrounding rod assembly 20 in the unfolded state and unable to be folded.

[0077] In the embodiments of the present application, the linkage unlocking mechanism 50 triggers the lock assembly 40 to release the locking of the surrounding rod assembly 20 at the moment when the support assembly 30 is folded upward, so as to improve the unlocking operation efficiency.

[0078] In combination with Figure 3 , Figure 6 and Figure 7 , the linkage unlocking mechanism 50 comprises a movable member 51, a traction member 52 and a linkage assembly 53.

[0079] The movable member 51 is movably connected to the first side frame 10a and can move to an unlocking position relative to the first side frame 10a.

[0080] The movable member 51 is connected to the lock assembly 40 through the traction member 52. The movable member 51 is connected to the third rod member 31 through the linkage assembly 53. When the foldable baby crib is in the unfolded state, the third rod member 31 is rotated relative to the first side frame 10a, and the third rod member 31 drives the movable member 51 to move to the unlocking position relative to the first side frame 10a through the linkage assembly 53, so that the traction member 52 drives the lock assembly 40 to release the locking.

[0081] In the above embodiments, the unlocking operation is simple, and only needs to place the movable member 51 in the unlocking position relative to the first side frame 10a, so as to realize the unlocking of the lock assembly 40, and then the surrounding rod assembly 20 and the support assembly 30 can be folded.

[0082] In combination with Figure 6 and Figure 7 , the end of the third rod member 31 close to the first side frame 10a is connected with a mounting seat 15, the third rod member 31 is rotatably connected with the mounting seat 15, and the mounting seat 15 is connected with the first side frame 10a. In this way, the third rod member 31 is rotatably connected with the first side frame 10a through the mounting seat 15.

[0083] In some embodiments, a first mounting hole 15a is formed in the mounting seat 15, a second mounting hole 31a is formed in the third rod member 31 corresponding to the position of the first mounting hole 15a, and a rotating shaft is arranged through the first mounting hole 15a and the second mounting hole 31a, so as to rotatably connect the third rod member 31 with the mounting seat 15 through the rotating shaft.

[0084] In combination with Figure 6 and Figure 7 , the end of the third rod member 31 close to the first side frame 10a is connected with a mounting seat 15, the third rod member 31 is rotatably connected with the mounting seat 15, and the mounting seat 15 is connected with the first side frame 10a. In this way, the third rod member 31 is rotatably connected with the first side frame 10a through the mounting seat 15.The movable member 51 is vertically movable relative to the mounting base 15. The mounting base 15 is provided with a sleeve hole 15b extending in the vertical direction. The movable member 51 is mounted in the sleeve hole 15b and is vertically movable in the sleeve hole 15b under the drive of the linkage assembly 53.

[0085] The two ends of the pulling member 52 are connected to the movable member 51 and the locking tongue 41 respectively. When the movable member 51 moves away from the locking tongue 41 relative to the mounting base 15, the pulling member 52 drives the locking tongue 41 to move away from the lock plug 42 under the drive of the movable member 51, so as to unlock the lock assembly 40.

[0086] It is to be noted that the linkage assembly 53 is connected between the movable member 51 and the third lever 31. When the third lever 31 rotates relative to the first side frame 40a, the third lever 31 drives the movable member 51 to move away from the locking tongue 41 through the linkage assembly 53.

[0087] In combination Figure 6 and Figure 7 The linkage assembly 53 comprises a telescopic member 531 and a rotary connecting member 532. The telescopic member 531 is telescopically connected to the third lever 31. The rotary connecting member 532 rotatably connects the telescopic member 531 and the movable member 51. The rotary connecting member 532 extends perpendicularly to the third lever 31.

[0088] In this embodiment, when the third lever 31 rotates relative to the mounting base 15, the telescopic member 531 rotates with the third lever 31. Thus, the telescopic member 531 drives the movable member 51 to move downward relative to the mounting base 15 through the rotary connecting member 532. The movable member 51 drives the locking tongue 41 to move away from the lock plug 42 through the pulling member 52, so as to separate the locking tongue 41 and the lock plug 42, thereby achieving the unlocking operation of the lock assembly 40.

[0089] It is to be noted that the telescopic member 531 is telescopically movable relative to the third lever 31. The rotary connecting member 532 rotatably connects the movable member 51 and the telescopic member 531. Thus, when the telescopic member 531 rotates with the third lever 31 relative to the mounting base 15, the telescopic member 531 is telescopically movable relative to the third lever 31 and rotates relative to the movable member 51 about the rotary connecting member 532. This structure can avoid the interference of the telescopic member 531 with the rotation of the third lever 31 relative to the mounting base 15.

[0090] In combination Figure 7As shown, the telescopic member 531 is provided with a clearance groove 531a at a position corresponding to the second mounting hole 31a, the rotating shaft penetrating the first mounting hole 15a and the second mounting hole 31a penetrates the clearance groove 531a, and the rotating shaft can move in the clearance groove 531a when the telescopic member 531 telescopes relative to the third rod member 31. Thus, when the telescopic member 531 telescopes relative to the third rod member 31, the clearance groove 531a can avoid the telescopic member 531 from being interfered by the rotating shaft.

[0091] Of course, in some embodiments, the clearance groove 531a can be omitted, as long as the distance from the second mounting hole 31a to one end of the telescopic member 531 provided on the third rod member 31 is large enough, so that the telescopic member 531 will not touch the rotating shaft during telescoping relative to the third rod member 31.

[0092] In the embodiments of the present application, the traction member 52 can be a linkage rope. Of course, in another embodiment, the traction member 52 can also be other flexible traction structures, which are not limited herein.

[0093] Optionally, the traction member 52 includes a steel wire rope and a protective sleeve. The length of the steel wire rope is less than the length of the protective sleeve, and the steel wire rope is movably arranged in the protective sleeve and can move relative to the protective sleeve along the length direction thereof.

[0094] Taking the case that the traction member 52 includes a steel wire rope, one end of the steel wire rope is connected with the movable member 51, and the other end of the steel wire rope is connected with the lock assembly 40. In this way, the steel wire rope plays a linkage role, and the protective sleeve plays a positioning role.

[0095] In the embodiments, two traction members 52 are provided, and both of the two traction members 52 are connected with the movable member 51. One end of one of the two traction members 52 away from the movable member 51 is connected with one of the lock assemblies 40, and one end of the other traction member 52 away from the movable member 51 is connected with the other lock assembly 40. In this way, when the third rod member 31 is lifted upward, the movable member 51 can drive the two lock assemblies 40 to move synchronously, so as to realize synchronous unlocking of the two lock assemblies 40.

[0096] One end of the traction member 52 away from the movable member 51 is connected with the lock tongue 41, that is, one end of the traction member 52 is connected with the movable member 51, and the other end is connected with the lock tongue 41, so that the movable member 51 can pull the lock tongue 41 through the traction member 52 when moving, so as to perform the unlocking operation. In the embodiments, the second end of the first rod member 21 and the second end of the second rod member 22 are both rotatably connected with the housing 43.

[0097] When the traction member 52 drives the lock tongue 41 to move away from the lock plug 42, the lock tongue 41 is separated from the lock plug 42, so that the lock assembly 40 is switched from the locked state to the unlocked state, and then the first rod member 21 and the second rod member 22 can rotate relative to the housing 43.

[0098] Referring again to Figure 4 and Figure 5 , the housing 43 is provided with a socket. The lock assembly 40 further comprises a limiting member 44, which is inserted into the socket, so that the limiting member 44 is connected with the housing 43. The lock tongue 41 is provided with a limiting groove 411.

[0099] In the locked state, the limiting member 44 is in limiting cooperation with the limiting groove 411, and the lock tongue 41 is not easy to retract into the first rod member 21 due to the possible slight rotation of the first rod member 21 and the second rod member 22, thereby improving the stability in the locked state. The cooperation between the limiting groove 411 of the lock tongue 41 and the limiting member 44 makes the lock tongue 41 unable to rotate relative to the housing 43 with the first rod member 21, thereby achieving the purpose of locking the rotation freedom of the first rod member 21. When the lock assembly 40 is unlocked, the movable member 51 pulls the lock tongue 41 through the traction member 52, so that the lock tongue 41 retracts into the first rod member 21, at this time, the lock tongue 41 is away from the limiting member 44. When the limiting member 44 retracts to a certain distance from the first rod member 21, the limiting member 44 is separated from the limiting groove 411, that is, the limiting member 44 is out of limiting cooperation with the limiting groove 411, and the limiting member 44 no longer limits the rotation of the lock tongue 41, and then the first rod member 21 can rotate relative to the housing 43.

[0100] Continuing to combine Figure 4 and Figure 5 , the housing 43 is provided with a first avoiding opening 431 on the side facing the first side frame 10a, a second avoiding opening 432 on the side facing the second side frame 10b, a third avoiding opening 433 on the side away from the support assembly 30, and a fourth avoiding opening 434 on the side away from the support assembly 30.

[0101] During the assembly of the foldable baby crib, the second end of the first rod member 21 is arranged in the housing 43 through the first avoiding opening 431, and the second end of the second rod member 22 is arranged in the housing 43 through the second avoiding opening 432. In this way, the first avoiding opening 431 and the second avoiding opening 432 can play a role of giving way, thereby facilitating the connection of the first rod member 21 and the second rod member 22 to the housing 43.

[0102] When the foldable baby crib is folded, combining Figure 1 and Figure 4The second end of the first rod member 21 rotates downward, and in the process of rotation, the second end of the first rod member 21 rotates from the first avoiding opening 431 to the third avoiding opening 433. At the same time, the second end of the second rod member 22 rotates downward, and in the process of rotation, the second end of the second rod member 22 rotates from the second avoiding opening 432 to the fourth avoiding opening 434. When the foldable baby crib is completely folded, the first rod member 21 is arranged in the third avoiding opening 433, and the second rod member 22 is arranged in the fourth avoiding opening 434, so that the third avoiding opening 433 and the fourth avoiding opening 434 can play a role of avoiding interference, avoiding interference of the shell 43 on the folding of the surrounding rod assembly 20.

[0103] In some embodiments, in combination Figure 4 and Figure 5 The shell 43 is sleeved on the second end of the first rod member 21 and the second end of the second rod member 22, so that the shell 43 can be used to coat the second end of the first rod member 21 and the second end of the second rod member 22, improve the appearance of the foldable baby crib when in use, and reduce the probability of being scratched by the first rod member 21 and the second rod member 22.

[0104] The rotating connection between the first rod member 21 and the second rod member 22 and the shell 43 has multiple possibilities.

[0105] For example, in some embodiments, in combination Figures 8 to 10 The shell 43 is provided with a first connecting hole 437, and the second end of the first rod member 21 is provided with a second connecting hole 211. The lock tongue 41 is provided with an avoiding hole 412, which is in the shape of a strip and extends along the length direction of the first rod member 21. The first connecting hole 437, the second connecting hole 211 and the avoiding hole 412 are in communication, and a first rotating connecting piece is arranged in the first connecting hole 437, the second connecting hole 211 and the avoiding hole 412. In this way, when the lock assembly 40 is switched between the locked state and the unlocked state, the lock tongue 41 will move along the length direction of the first rod member 21, and because the avoiding hole 412 of the lock tongue 41 is in the shape of a strip, the strip-shaped avoiding hole 412 can avoid the first rotating connecting piece.

[0106] Further, the shell 43 is also provided with a third connecting hole 438. The second end of the second rod member 22 is provided with a fourth connecting hole 221, and the lock plug 42 is provided with a fifth connecting hole 421. The third connecting hole 438, the fourth connecting hole 221 and the fifth connecting hole 421 are in communication, and a second rotating connecting piece is arranged in the third connecting hole 438, the fourth connecting hole 221 and the fifth connecting hole 421.

[0107] In combination Figure 9 and Figure 10The shell 43 is provided with a limiting hole 435 and an arc hole 436 in communication with the limiting hole 435. The limiting hole 435 is arranged corresponding to the position between the first rod 21 and the second rod 22, and the arc hole 436 is arranged corresponding to the second end of the first rod 21.

[0108] Further, in combination with Figures 9 to 11 The lock assembly 40 further comprises a sliding piece 45 arranged on the lock tongue 41. In the locked state, the sliding piece 45 is arranged in the limiting hole 435. The sliding piece 45 can move in the arc hole 436 in a direction away from the limiting hole 435, so as to switch the lock assembly 40 from the locked state to the unlocked state. In the unlocked state, the sliding piece 45 is located in the arc hole 436.

[0109] If the foldable crib needs to be folded, the third rod 31 is lifted upward, and the third rod 31 drives the lock tongue 41 to move away from the lock plug 42 through the linkage unlocking mechanism 50, that is, under the driving of the traction piece 52, the sliding piece 45 slides from the limiting hole 435 to the arc hole 436 and moves in the arc hole 436 in a direction away from the limiting hole 435. In this way, when the sliding piece 45 slides in the arc hole 436, on the one hand, the lock assembly 40 can be switched from the locked state to the unlocked state, and on the other hand, the second end of the first rod 21 can be driven to rotate downward.

[0110] If the foldable crib needs to be unfolded, the sliding piece 45 moves in the arc hole 436 in a direction close to the limiting hole 435 until the sliding piece 45 slides into the limiting hole 435. The hole wall of the limiting hole 435 limits the sliding piece 45, so that the lock tongue 41 is fixed relative to the shell 43, and at the same time, the lock plug 42 is lapped on the lock tongue 41, so that the surrounding rod assembly 20 is fixed relative to the side frame 10.

[0111] In addition, in cooperation with the arc hole 436 and the sliding piece 45, the movement of the sliding piece 45 is guided, the stability of the movement of the sliding piece 45 is improved, and the smoothness of unfolding and folding of the foldable crib is ensured.

[0112] Further, in combination with Figure 9 The arc hole 436 takes the first connecting hole 437 as the center. In this way, the first rod 21 rotates around the first connecting hole 437, avoiding interference of the arc hole 436 with the rotation of the first rod 21, and ensuring the smoothness of the rotation of the first rod 21.

[0113] In combination with Figure 10 And Figure 11 The lock assembly 40 further comprises an elastic reset piece 46. The elastic reset piece 46 is connected with the lock tongue 41 and the first rod 21, and the elastic reset piece 46 stretches and contracts along the length direction of the first rod 21. The elastic reset piece 46 is used to drive the lock tongue 41 to move in a direction close to the lock plug 42.

[0114] In combination Figure 11 During the unlocking operation, the third lever 31 is lifted upward, and the third lever 31 drives the lock tongue 41 to move away from the lock plug 42 through the linkage unlocking mechanism 50, and the elastic return member 46 is gradually compressed.

[0115] In combination Figure 11 And Figure 12 When the traction member 52 drives the lock tongue 41 to move away from the lock plug 42 to separate the lock tongue 41 from the lock plug 42, the first lever 21 and the second lever 22 can rotate relative to the shell 43 because the lock assembly 40 switches from the locked state to the unlocked state.

[0116] It should be noted that when the lock assembly 40 is in the unlocked state, the foldable baby crib can be folded under the gravity of some structures of itself, or can be folded by, for example, the user's inward extrusion force on the side frame 10.

[0117] For example, in combination Figure 13 When the lock assembly 40 is unlocked, the second ends of the first lever 21 and the second lever 22 rotate downward under the gravity, so that the first ends of the first lever 21 and the second lever 22 are folded toward the middle. At the same time, the first side frame 10a and the second side frame 10b approach each other, and the second ends of the third lever 31 and the fourth lever 32 are flipped upward at the folding joint 33 position, so that the first ends of the third lever 31 and the fourth lever 32 are folded toward the middle. Based on this, as the first side frame 10a and the second side frame 10b approach each other, the overall folding of the foldable baby crib is ultimately realized, which is beneficial to reduce the volume of the foldable baby crib and reduce the space required for storing the foldable baby crib. In addition, the folding steps of the foldable baby crib can be simplified, and the folding efficiency can be improved.

[0118] In combination Figure 14 When the foldable baby crib is completely folded, the first side frame 10a and the second side frame 10b are attached to each other.

[0119] In some embodiments, the folding of the foldable baby crib can be powered by setting an elastic member, so that the folding operation is more relaxed. The setting of the elastic member has many possibilities, as long as the elastic force of the elastic member can provide power for the folding of the surrounding rod assembly 20 or the support assembly after the lock assembly 40 is unlocked.

[0120] For example, in combination Figure 8In some embodiments, the locking assembly 40 further comprises a folding spring 47. One end of the folding spring 47 is connected to the housing 43, and the other end of the folding spring 47 is connected to the first rod 21 and / or the second rod 22. When the locking assembly 40 is unlocked, the folding spring 47 is used to drive the second end of the first rod 21 and / or the second rod 22 to rotate downward. In this way, the folding efficiency is improved by using the gravity of the first rod 21 and the second rod 22 and the elastic force of the folding spring 47 to fold the surrounding rod assembly 20 quickly.

[0121] Optionally, the folding spring 47 is provided with one. One end of the folding spring 47 is connected to the housing 43, and the other end of the folding spring 47 is connected to the first rod 21; or one end of the folding spring 47 is connected to the housing 43, and the other end of the folding spring 47 is connected to the second rod 22, so as to avoid the motion interference between the folding spring 47 and the sliding member 45.

[0122] Optionally, the folding spring 47 is provided with two. One end of one folding spring 47 is connected to the first rod 21, and the other end of the folding spring 47 is connected to the housing 43. One end of the other folding spring 47 is connected to the second rod 22, and the other end of the folding spring 47 is connected to the housing 43. In this way, the folding efficiency can be further improved.

[0123] In some embodiments, one end of the surrounding rod assembly 20 is movably connected to the first side frame 10a, and the other end of the surrounding rod assembly 20 is movably connected to the second side frame 10b. The surrounding rod assembly 20 can move along the height direction of the first side frame 10a and the second side frame 10b to realize the lifting of the surrounding rod assembly 20. When in use, the surrounding rod assembly 20 can be pulled down, which is convenient for placing and taking out the baby from the foldable baby crib. When the foldable baby crib is placed beside an adult, the surrounding rod assembly 20 can be pulled down, which is convenient for the adult to take care of the baby without getting up. In addition, under normal circumstances, the surrounding rod assembly 20 can be pulled up to ensure the safety of the baby.

[0124] One end of the support assembly 30 is movably connected to the first side frame 10a, and the other end of the support assembly 30 is movably connected to the second side frame 10b. When in use, the support assembly 30 can move along the height direction of the first side frame 10a and the second side frame 10b to realize the lifting of the support assembly 30.

[0125] In some embodiments, the first side frame 10a and the second side frame 10b are both telescopic along their length. Specifically, the first support 11 and the second support 12 are telescopic rods, the first support 11 is telescopic along its length, and the second support 12 is telescopic along its length. When the foldable baby crib is folded, the first support 11 and the second support 12 can be telescoped to reduce the height of the foldable baby crib, so as to reduce the packaging and transportation space and the transportation cost without disassembling the foldable baby crib.

[0126] It should be noted that the foldable baby crib can be supported on the ground in a foot type or in a wheel type.

[0127] In combination Figure 15 , in some embodiments, the foldable baby crib further comprises a synchronization mechanism 60. One end of the synchronization mechanism 60 is rotatably connected to the first side frame 10a, and the other end of the synchronization mechanism 60 is rotatably connected to the second side frame 10b. In this way, the left structure and the right structure of the lock assembly 40 can be kept synchronized and consistent when unfolded and folded, for example. Figure 13

[0128] Further, in combination Figures 13 to 15 , the synchronization mechanism 60 comprises a fifth rod member 61, a synchronization wheel set 63, and a sixth rod member 62. The first end of the fifth rod member 61 is rotatably connected to the first side frame 10a, and the first end of the sixth rod member 62 is rotatably connected to the second side frame 10b. The synchronization wheel set 63 is rotatably arranged in the housing 43, and the synchronization wheel set 63 is arranged at the second end of the fifth rod member 61 and the second end of the sixth rod member 62. In this way, the synchronization wheel set 63 has rotational freedom and rotates smoothly, and during the unfolding and folding of the surrounding rod assembly 20 and the support assembly 30, the synchronization wheel set 63 plays a role in synchronously maintaining the surrounding rod assembly 20 and the support assembly 30, avoiding asynchronous action to affect the unfolding and folding effect.

[0129] Optionally, in combination Figure 10 , Figure 12 and Figure 15 , the synchronization wheel set 63 comprises a first fixed gear 631, a first movable gear 632, a second fixed gear 633, and a second movable gear 634. The first fixed gear 631 is arranged at the second end of the fifth rod member 61, the second fixed gear 633 is arranged at the second end of the sixth rod member 62, the first movable gear 632 and the second movable gear 634 are located between the first fixed gear 631 and the second fixed gear 633 and are rotatably connected to the housing 43, the first fixed gear 631 is engaged with the first movable gear 632, the first movable gear 632 is engaged with the second movable gear 634, and the second movable gear 634 is engaged with the second fixed gear 633.

[0130] ​Of course, in another embodiment, the synchronous wheel set 63 can also be a synchronous pulley, without being limited thereto.

[0131] Again, in combination Figure 8 The foldable crib further comprises a mattress 70. The mattress 70 is arranged on the support assembly 30. In use, the infant is placed on the mattress 70, and the mattress 70 serves to support the infant.

[0132] Optionally, in combination Figure 8 The mattress 70 comprises a first pad 71 and a second pad 72.

[0133] The first pad 71 and the second pad 72 can each be a hard pad. The first pad 71 is arranged between the first side frame 10a and the folding joint 33, and the second pad 72 is arranged between the second side frame 10b and the folding joint 33. The first pad 71 and the second pad 72 are foldably connected.

[0134] Optionally, the first pad 71 is connected to the second pad 72 by a soft fabric. In this way, when the foldable crib is folded, the mattress 70 does not need to be disassembled, so that the mattress 70 can be folded together with the bed frame, simplifying the unfolding and folding steps of the foldable crib and improving the unfolding and folding efficiency of the foldable crib.

[0135] In some embodiments, in combination Figure 2 The mattress 70 comprises a first pad 71, a second pad 72, and a third pad 73.

[0136] The first pad 71, the second pad 72, and the third pad 73 can each be a hard pad. The first pad 71 is arranged between the first side frame 10a and the folding joint 33, the second pad 72 is arranged between the second side frame 10b and the folding joint 33, and the third pad 73 is arranged corresponding to the folding joint 33. The first pad 71 is connected to the third pad 73 by a soft fabric, and the second pad 72 is connected to the third pad 73 by a soft fabric. In this way, when the foldable crib is folded, the mattress 70 does not need to be disassembled, so that the mattress 70 can be folded together with the bed frame, simplifying the unfolding and folding steps of the foldable crib and improving the unfolding and folding efficiency of the foldable crib.

[0137] In combination Figure 8 The bottom of the first side frame 10a and the second side frame 10b is provided with a moving wheel 80. In this way, the transfer of the foldable crib is facilitated.

[0138] Further, the moving wheel 80 is provided with a brake. In this way, the foldable crib can be stably stopped at the use location. Optionally, the brake can be manually controlled or controlled by stepping.
