DETAILED DESCRIPTION

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full 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 violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0051] The foldable crib provided in one embodiment of the present application can be switched between an unfolded state and a folded state. In the folded state, the foldable crib is small in size, which helps to reduce the occupied space and is easy to carry and store. In the unfolded state, the foldable crib can provide a play or sleep space for infants.

[0052] Combination Figure 1 and Figure 2 The foldable baby bed includes a side frame 10, a linkage unlocking mechanism 20, a surrounding rod assembly 30 and a supporting assembly 40.

[0053] There are two side frames 10. For ease 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 at intervals along a first direction. S1 is used to represent the first direction.

[0054] The first side frame 10 a and the second side frame 10 b each include a first support member 11 , a second support member 12 , a guardrail 13 , and a reinforcement member 14 .

[0055] The first support member 11 and the second support member 12 are spaced apart along the second direction, and the first direction is perpendicular to the second direction. S2 is used to represent the second direction. Both ends of the guardrail 13 are connected to the upper part of the first support member 11 and the upper part of the second support member 12 respectively.

[0056] Two ends of the reinforcing member 14 are connected to the lower portion of the first supporting member 11 and the lower portion of the second supporting member 12 respectively.

[0057] Optionally, the first support member 11, the second support member 12, the guardrail 13 and the reinforcement member 14 are connected to form an integrated rectangular frame, so that the production and processing are convenient, and the assembly efficiency of the foldable baby bed is improved.

[0058] In another embodiment, the first support member 11 is detachably connected to the guardrail 13 and the reinforcement member 14, and the second support member 12 is detachably connected to the guardrail 13 and the reinforcement member 14. In this way, the first side frame 10a and the second side frame 10b can be detached, which is beneficial to reducing the packaging volume of the foldable baby crib and reducing the transportation cost.

[0059] The connection method of each structure in the first side frame 10a and the second side frame 10b and the structure of the surrounding rod assembly 30 are not limited here. As long as the first side frame 10a and the second side frame 10b can be close to each other during the folding process of the foldable baby crib to meet the folding needs of the foldable baby crib.

[0060] Continue to combine Figure 1 and Figure 2 There are two surrounding rod assemblies 30, and the two surrounding rod assemblies 30 are arranged between the first side frame 10a and the second side frame 10b and are spaced apart along the second direction. It can be understood that both ends of the two surrounding rod assemblies 30 in the second direction are connected between the first side frame 10a and the second side frame 10b.

[0061] Optionally, the surrounding rod assembly 30 is detachably connected to 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.

[0062] Continue to combine Figure 1 The two enclosure rod assemblies 30 each include a first rod 31 and a second rod 32. The first end of the first rod 31 is rotatably connected to the first side frame 10a, the first end of the second rod 32 is rotatably connected to the second side frame 10b, and the second end of the first rod 31 is rotatably connected to the second end of the second rod 32.

[0063] Optionally, the first rod 31 and the second rod 32 are hollow tubes. For example, the first rod 31 and the second 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 first rod 31 and the second rod 32 can also be solid rods.

[0064] There are two support assemblies 40, both of which are arranged between the first side frame 10a and the second side frame 10b and spaced apart along the second direction. One end of the support assembly 40 is connected to the first side frame 10a, and the other end of the support assembly 40 is connected to the second side frame 10b.

[0065] Optionally, the support assembly 40 is detachably connected to 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.

[0066] Combination Figure 3 The support assembly 40 includes a third rod 41, a fourth rod 42 and a folding joint 43. The first end of the third rod 41 is rotatably connected to the first side frame 10a. The first end of the fourth rod 42 is rotatably connected to the second side frame 10b. The second end of the third rod 41 is rotatably connected to the second end of the fourth rod 42 via the folding joint 43.

[0067] Optionally, the third rod 41 and the fourth rod 42 are hollow tubes. For example, the third rod 41 and the fourth rod 42 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 41 and the fourth rod 42 can also be solid rods.

[0068] It should be noted that, for a foldable crib that is a cubic frame structure in an unfolded state, the connecting portion of the surrounding rod assembly 30 and the support assembly 40 can share a common structural member. For example, the reinforcement member 14 in the surrounding rod assembly 30 can also be used as a part of the support assembly 40.

[0069] In some embodiments, the reinforcement 14 can also be removed from the side frame 10 and used as a part of the support assembly 40. When the support assembly 40 is installed between the first side frame 10a and the second side frame 10b, the reinforcement 14 is located between the first support member 11 and the second support member 12.

[0070] In this embodiment, reinforcement members 14 may be respectively provided at both ends of the support assembly 40, and the reinforcement members 14 on the corresponding sides are correspondingly mounted on the first side frame 10a and the second side frame 10b.

[0071] Furthermore, the installation heights of the reinforcement members 14 at both ends of the support assembly 40 on the first side frame 10 a and the second side frame 10 b are adjustable, so that the installation height of the support assembly 40 can be adjusted.

[0072] It should be noted that the support assembly 40 can be lifted up and lowered so that the foldable baby bed can achieve different functions. For example, when in use, the foldable baby bed is placed next to the adult bed, and the support assembly 40 is lifted up so that the adult and the infant are basically at the same height, which is convenient for the adult to take care of the infant. At this time, the foldable baby bed can achieve the function of providing a resting place. For another example, the support assembly 40 is lowered so that the infant can play in the foldable baby bed without falling out. At this time, the foldable baby bed can achieve the function of providing a playing place, that is, a playbed.

[0073] In order to prevent the foldable baby crib from being accidentally folded during use, the foldable baby crib of the present application also has a locking function for locking the unfolded state and an unlocking function for releasing the lock.

[0074] For ease of understanding, the state in which the foldable baby crib is unfolded and locked is referred to as a "locked state", and the state in which the foldable baby crib is unlocked and folded is referred to as an "unlocked state".

[0075] Specifically, when the foldable crib is in a locked state, the surrounding rod assembly 30 cannot be folded because it is locked, that is, the rotational freedom between the first rod 31 and the second rod 32 is locked, so that the first rod 31 and the second rod 32 cannot rotate relative to each other and fold. Correspondingly, when the foldable crib is in a locked state, the support assembly 40 cannot be folded because it is locked, that is, the rotational freedom between the third rod 41 and the fourth rod 42 is locked, so that the third rod 41 and the fourth rod 42 cannot rotate relative to each other and fold.

[0076] In the embodiment of the present application, the linkage unlocking mechanism 20 can not only unlock the surrounding rod assembly 30, but also unlock the supporting assembly 40, thereby achieving the effect of improving the efficiency of the unlocking operation.

[0077] For ease of understanding, the structure and principle of the linkage unlocking mechanism 20 will be described below in conjunction with the locking structures on the surrounding rod assembly 30 and the support assembly 40. However, it does not mean that the structure for locking the rotational freedom between the first rod 31 and the second rod 32, and the structure for locking the rotational freedom between the third rod 41 and the fourth rod 42 are limited to this.

[0078] Combination Figure 2 and Figure 3 The foldable crib further comprises a first lock assembly 50 and a second lock assembly 60. When the foldable crib is in the unfolded state, the first lock assembly 50 restricts the first rod 31 and the second rod 32 from rotating relative to each other, and the second lock assembly 60 restricts the third rod 41 and the fourth rod 42 from rotating relative to each other.

[0079] It should be noted here that since the locking and unlocking of the foldable crib both refer to the locking or unlocking of the foldable crib by the corresponding lock assembly when the foldable crib is in the unfolded state, the locking of the foldable crib can be understood as the first lock assembly 50 and the second lock assembly 60 being in the locked state; correspondingly, the unlocking of the foldable crib can be understood as the first lock assembly 50 and the second lock assembly 60 being in the unlocked state.

[0080] Combination Figure 3 The linkage unlocking mechanism 20 includes an operating member 21 , a first traction member 22 and a second traction member 23 .

[0081] The operating member 21 is movably connected to the side frame 10 and can move to an unlocking position relative to the side frame 10. The operating member 21 is linked to the first lock assembly 50 through the first traction member 22, and is linked to the second lock assembly 60 through the second traction member 23.

[0082] When the foldable baby bed is in the unfolded state, the operating member 21 is moved to the unlocking position relative to the side frame 10, so that the first traction member 22 and the second traction member 23 are respectively linked to the first lock assembly 50 and the second lock assembly 60 to unlock. In this way, the first lock assembly 50 no longer restricts the first rod 31 and the second rod 32 from rotating relative to each other; the second lock assembly 60 no longer restricts the third rod 41 and the fourth rod 42 from rotating relative to each other.

[0083] In this embodiment, the unlocking operation is simple. It is only necessary to place the operating member 21 in the unlocking position relative to the side frame 10 to unlock the first lock assembly 50 and the second lock assembly 60, thereby allowing the surrounding rod assembly 30 and the support assembly 40 to be folded.

[0084] In the embodiment of the present application, the first traction member 22 and the second traction member 23 may be a linkage rope. Of course, in another embodiment, the first traction member 22 and the second traction member 23 may also be other flexible traction structures, which are not limited here.

[0085] Optionally, the linkage rope 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, the steel wire rope is movably arranged in the protective sleeve, and the steel wire rope can move relative to the protective sleeve along its length direction.

[0086] Taking the first traction member 22 including a steel wire rope as an example, one end of the steel wire rope is connected to the operating member 21, and the other end of the steel wire rope is connected to the first lock assembly 50. In this way, the steel wire rope plays a role of linkage, and the protective cover plays a role of positioning.

[0087] In this embodiment, two first pulling members 22 are provided, and both first pulling members 22 are connected to the operating member 21, wherein one end of one first pulling member 22 away from the operating member 21 is connected to one of the first lock assemblies 50, and the other end of the other first pulling member 22 away from the operating member 21 is connected to the other first lock assembly 50. In this way, when the operating member 21 is turned outward, the operating member 21 can drive the two first lock assemblies 50 to move synchronously, thereby realizing synchronous unlocking of the two first lock assemblies 50.

[0088] Combination Figure 4 and Figure 5 The first lock assembly 50 is disposed at the second end of the first rod 31 and the second end of the second rod 32 , and the first rod 31 is rotatably connected to the second rod 32 through the first lock assembly 50 .

[0089] It can be understood that both the first lock assembly 50 and the second lock assembly 60 have a locked state and an unlocked state.

[0090] Combination Figure 1When the first lock assembly 50 and the second lock assembly 60 are both in the unlocked state, the first rod 31 and the second rod 32 can rotate relative to the side frame 10, and the third rod 41 and the fourth rod 42 can rotate relative to the side frame 10, so that the foldable baby bed can be folded and collapsed.

[0091] Combination Figure 2 When the first lock assembly 50 is in the locked state, the first rod 31 and the second rod 32 are coaxially arranged, and the third rod 41 and the fourth rod 42 are both fixed relative to the side frame 10. When the second lock assembly 60 is in the locked state, the third rod 41 and the fourth rod 42 are coaxially arranged, and the third rod 41 and the fourth rod 42 are both fixed relative to the side frame 10.

[0092] Continue to combine Figure 2 and Figure 3 There are two first lock assemblies 50. One of the first lock assemblies 50 is disposed at the second end of one of the first rods 31 and the second end of the second rod 32 corresponding thereto, and the other first lock assembly 50 is disposed at the second end of the other first rod 31 and the second end of the second rod 32 corresponding thereto.

[0093] The operating member 21 can be an unlocking wrench, so that the unlocking operation can be performed by rotating. For example, the operating member 21 can be reversibly mounted on the side frame 10. Optionally, the operating member 21 can be reversibly arranged on the guardrail 13.

[0094] Optionally, the operating member 21 is flippably disposed on a side of the first side frame 10a away from the second side frame 10b. When unlocking, the operating member 21 flips in a direction away from the second side frame 10b, which is convenient for operation.

[0095] The first traction member 22 switches the first lock assembly 50 from the locked state to the unlocked state by the rotation of the operating member 21 relative to the side frame 10. Correspondingly, the rotation of the operating member 21 relative to the side frame 10 can also switch the first lock assembly 50 from the locked state to the unlocked state via the second traction member 23.

[0096] In some embodiments, the operating member 21 can be rotated outwardly relative to the side frame 10 to an unlocked position. In this embodiment, if the foldable baby bed needs to be folded, the operating member 21 is flipped outward, and the operating member 21 can be used to drive the first lock assembly 50 and the second lock assembly 60 to perform an unlocking action through the first traction member 22 and the second traction member 23, respectively, so that the first lock assembly 50 and the second lock assembly 60 are switched from the locked state to the unlocked state.

[0097] Combination Figure 4 and Figure 5The first lock assembly 50 includes a lock tongue 51, a lock plug 52 and a housing 53. The lock tongue 51 is movably disposed at the second end of the first rod 31, and the lock plug 52 is disposed at the second end of the second rod 32. One end of the first traction member 22 away from the operating member 21 is connected to the lock tongue 51, that is, one end of the first traction member 22 is connected to the operating member 21, and the other end is connected to the lock tongue 51, so that when the operating member 21 moves, the lock tongue 51 can be pulled by the first traction member 22 to perform an unlocking operation. In this embodiment, the second end of the first rod 31 and the second end of the second rod 32 are both rotatably connected to the housing 53.

[0098] Continue to combine Figure 4 and Figure 5 In the locked state, the lock plug 52 overlaps the lock tongue 51 and restricts the first rod 21 and the second rod 22 from rotating relative to the housing 53, thereby keeping the surrounding rod assembly 20 in the unfolded state and not foldable. When the first traction member 22 drives the lock tongue 51 to move away from the lock plug 52, the lock tongue 51 separates from the lock plug 52, thereby switching the first lock assembly 50 from the locked state to the unlocked state, and then the first rod 21 and the second rod 22 can rotate relative to the housing 53.

[0099] Furthermore, the housing 53 is provided with an insertion hole 537. The first lock assembly 50 further includes a stopper 54, which is inserted into the insertion hole 537 so that the stopper 54 is connected to the housing 53. The lock tongue 51 is provided with a stopper groove 511.

[0100] In the locked state, the limiting member 54 cooperates with the limiting groove 511, and the lock tongue 51 is not easily retracted into the first rod 31 due to the possible slight rotation of the first rod 31 and the second rod 32, thereby improving the stability in the locked state. The cooperation between the limiting groove 511 of the lock tongue 51 and the limiting member 54 makes it impossible for the lock tongue 51 to rotate relative to the housing 53 with the first rod 31, thereby achieving the purpose of locking the rotational freedom of the first rod 31. When the first lock assembly 50 is unlocked, the operating member 21 pulls the lock tongue 51 through the first pulling member 22, so that the lock tongue 51 shrinks into the first rod 31. At this time, the lock tongue 51 is away from the limiting member 54. When the limiting member 54 contracts to a certain distance toward the first rod 31 , the limiting member 54 separates from the limiting groove 511 , that is, the limiting member 54 and the limiting groove 511 are released from the limiting cooperation, and the limiting member 54 no longer restricts the rotation of the locking tongue 51 , and then the first rod 31 can rotate relative to the shell 53 .

[0101] Combination Figure 4 and Figure 5A first avoidance opening 531 is provided on the side of the shell 53 facing the first side frame 10a, a second avoidance opening 532 is provided on the side of the shell 53 facing the second side frame 10b, and a third avoidance opening 533 connected to the first avoidance opening 531 and a fourth avoidance opening 534 connected to the second avoidance opening 532 are provided on the side of the shell 53 away from the support assembly 40.

[0102] During the assembly of the foldable crib, the second end of the first rod 31 can be disposed in the shell 53 through the first avoidance opening 531, and the second end of the second rod 32 can be disposed in the shell 53 through the second avoidance opening 532. In this way, the first avoidance opening 531 and the second avoidance opening 532 can play a role of giving way, thereby facilitating the connection of the first rod 31 and the second rod 32 to the shell 53.

[0103] When the foldable crib is folded, Figure 1 , the second end of the first rod 31 rotates downward, and during the rotation process, the second end of the first rod 31 rotates from the first avoidance opening 531 to the third avoidance opening 533. At the same time, the second end of the second rod 32 rotates downward, and during the rotation process, the second end of the second rod 32 rotates from the second avoidance opening 532 to the fourth avoidance opening 534. When the foldable baby bed is fully folded, the first rod 31 is located at the third avoidance opening 533, and the second rod 32 is located at the fourth avoidance opening 534, so that the third avoidance opening 533 and the fourth avoidance opening 534 can play a role of giving way, thereby preventing the shell 53 from interfering with the folding of the surrounding rod assembly 30.

[0104] In some embodiments, the second lock assembly 60 may have the same structure as the first lock assembly 50, as long as the second lock assembly 60 can adapt to the need to lock and unlock the rotational freedom of the third rod 41 and the fourth rod 42. In this embodiment, since the first lock assembly 50 and the second lock assembly 60 have the same structure, it is conducive to unifying the standards of structural parts and facilitating the reduction of the cost of replacing parts.

[0105] In other embodiments, the second lock assembly 60 may also adopt a structure different from that of the first lock assembly 50 .

[0106] For example, combined with Figure 4 and Figure 6 The end of the reinforcement member 14 is connected to the mounting seat 15 , and the third rod member 41 is rotatably connected to the mounting seat 15 . In this way, the reinforcement member 14 is connected to the third rod member 41 through the mounting seat 15 .

[0107] Combination Figures 7 to 9The second lock assembly 60 includes a locking member 61, a reset elastic member 62, and a transmission assembly 63. The locking member 61 is movably connected to the mounting seat 15, and this movably connected includes but is not limited to the locking member 61 being directly movably connected to the mounting seat 15. In some embodiments, the locking member 61 may also be movably connected to the reinforcement member 14, so that when the end of the reinforcement member 14 is connected to the mounting seat 15, the locking member 61 is movably connected to the mounting seat 15.

[0108] When the foldable baby crib is in the unfolded state, the locking member 61 can extend into the third rod 41 under the elastic force of the reset elastic member 62 to limit the third rod 41 from rotating relative to the mounting seat 15. Then, the third rod 41 will not rotate relative to the fourth rod 42, thereby achieving the effect of locking the rotational freedom of the third rod 41 and the fourth rod 42.

[0109] The transmission assembly 63 is used to move the locking member 61 in a direction away from the third rod 41 under the drive of the second traction member 23, so that the locking member 61 overcomes the elastic force of the reset elastic member 62 and moves out of the third rod 41. In this way, the locking member 61 releases the lock on the third rod 41, so that the third rod 41 recovers the rotational freedom relative to the mounting seat 15, and then the support assembly 40 can be folded.

[0110] Combination Figure 8 In some embodiments, the reinforcement member 14 is a hollow tube, and a first guide groove 14a is provided on the tube wall near the end. The length direction of the first guide groove 14a is the same as the movement direction of the locking member 61, that is, the same as the extension direction of the third rod 41.

[0111] Combination Figure 8 and Fig. 9 The transmission assembly 63 includes a first transmission member 631 and a second transmission member 632. The first transmission member 631 is provided with a guide hole 631a and a second guide groove 631b penetrating the side wall of the guide hole 631a. One end of the locking member 61 away from the third rod 41 is slidably fitted in the guide hole 631a, and the locking member 61 is connected with a guide pin 61a.

[0112] The guide pin 61a is inserted into the first guide groove 14a and the second guide groove 631b. The length direction of the second guide groove 631b intersects with the length direction of the first guide groove 14a. The first transmission member 631 is telescopically arranged in the reinforcement member 14 so that the groove wall of the second guide groove 631b pushes the guide pin 61a to move along the first guide groove 14a.

[0113] When the guide pin 61a moves along the first guide groove 14a, the locking member 61 moves out of the third rod 41, and then the locking member 61 releases the lock on the third rod 41, so that the third rod 41 recovers the rotational freedom relative to the mounting seat 15, and then the support assembly 40 can be folded.

[0114] It should be noted that the second transmission member 632 only needs to transmit power to the first transmission member 631 driven by the second traction member 23 so that the first transmission member 631 drives the guide pin 61a to move along the first guide groove 14a in a direction away from the third rod 41.

[0115] For example, combined with Figures 7 to 9 The second transmission member 632 is connected to the second traction member 23, and can move upward relative to the mounting base 15 in the vertical direction under the drive of the first traction member 22. The second transmission member 632 is provided with an inclined surface 632a on the side facing the first transmission member 631, and a part of the structure of the first transmission member 631 extends out of the reinforcement member 14 and abuts against the inclined surface 632a.

[0116] When the first traction member 22 drives the second transmission member 632 to move relative to the mounting seat 15, the inclined surface 632a of the second transmission member 632 pushes the first transmission member 631 into the reinforcement member 14, so that the first transmission member 631 drives the guide pin 61a to move along the first guide groove 14a in a direction away from the third rod 41. Then the guide pin 61a moves along the first guide groove 14a and drives the locking member 61 to move out of the third rod 41, so that the locking member 61 releases the lock on the third rod 41.

[0117] An elastic member for realizing the reset movement of the operating member 21 may be provided in the side frame 10, so that after the operating member 21 is rotated to the unlocked position, when the user releases the control of the operating member 21, the operating member 21 can reset inwardly relative to the side frame 10 from the unlocked position, so as to avoid the operating member 21 being too protruding outside the side frame 10 and affecting the appearance or being easily scratched.

[0118] For example, combining 7 and Fig.10 The linkage unlocking mechanism 20 further includes a first elastic reset member 24. The first elastic reset member 24 is connected to the operating member 21 and the first side frame 10a, and the first elastic reset member 24 is used to drive the operating member 21 to reset.

[0119] It should be noted that the first elastic reset member 24 can be directly connected to the operating member 21 or connected to the operating member 21 through other structural members, as long as the operating member 21 can be reset. Fig.10The linkage unlocking mechanism 20 further includes a slider 25, which is disposed on the first side frame 10a and can slide under the drive of the operating member 21. In this embodiment, the first elastic reset member 24 can be connected to the slider 25, and by driving the slider 25 to slide relative to the first side frame 10a, the slider 25 drives the operating member 21 to reset. The first traction member 22 and the second traction member 23 are both fixedly connected to the slider 25. In this way, when the operating member 21 is used to perform the unlocking operation, the operating member 21 can drive the slider 25 to move while causing the first traction member 22 and the second traction member 23 to respectively unlock the first lock assembly 50 and the second lock assembly 60.

[0120] In the embodiment where the operating member 21 is reversibly mounted on the side frame 10, the first elastic reset member 24 may be a torsion spring. For example, one end of the torsion spring is connected to the operating member 21, and the other end of the torsion spring is connected to the first side frame 10a.

[0121] When unlocking, an external force acts on the operating member 21, and the operating member 21 flips in a direction away from the second side frame 10b, and the first elastic reset member 24 is elastically deformed. After unlocking is completed, the external force acting on the operating member 21 is removed, and the first elastic reset member 24 recovers its deformation to drive the operating member 21 to flip in the opposite direction, thereby realizing the reset of the operating member 21.

[0122] In some embodiments, in combination Fig.11 and Fig.12 The shell 53 is sleeved on the second end of the first rod 31 and the second end of the second rod 32. In this way, the shell 53 can be used to cover the second end of the first rod 31 and the second end of the second rod 32, thereby improving the appearance of the foldable baby bed when in use and reducing the chance of being scratched by the first rod 31 and the second rod 32.

[0123] There are many possible ways to set the rotational connection between the first rod 31 and the second rod 32 and the housing 53 .

[0124] For example, in some embodiments, in combination Figures 11 to 16 The housing 53 is provided with a first connection hole 538, and the second end of the first rod 31 is provided with a second connection hole 311. The lock tongue 51 is provided with an avoidance hole 512, which is in a strip shape and extends along the length direction of the first rod 31. The first connection hole 538, the second connection hole 311 and the avoidance hole 512 are connected, and a first rotating connection member is provided in the first connection hole 538, the second connection hole 311 and the avoidance hole 512. In this way, when the first lock assembly 50 switches between the locked state and the unlocked state, the lock tongue 51 will move along the length direction of the first rod 31, and since the avoidance hole 512 of the lock tongue 51 is in a strip shape, the strip-shaped avoidance hole 512 can give way to the first rotating connection member.

[0125] Furthermore, the housing 53 is further provided with a third connection hole 539. The second end of the second rod 32 is provided with a fourth connection hole 321, the lock plug 52 is provided with a fifth connection hole 521, the third connection hole 539, the fourth connection hole 321 and the fifth connection hole 521 are connected, and the third connection hole 539, the fourth connection hole 321 and the fifth connection hole 521 are provided with a second rotating connection member.

[0126] Combination Fig.12 and Fig.14 The housing 53 is provided with a limiting hole 535 and an arc hole 536 connected to the limiting hole 535. The limiting hole 535 is arranged corresponding to the position between the first rod 31 and the second rod 32, and the arc hole 536 is arranged corresponding to the second end of the first rod 31.

[0127] Further, the first lock assembly 50 further includes a sliding member 55, which is disposed on the lock tongue 51. In the locked state, the sliding member 55 is disposed in the limiting hole 535. The sliding member 55 can move in the arc hole 536 in a direction away from the limiting hole 535, so that the first lock assembly 50 is switched from the locked state to the unlocked state. In the unlocked state, the sliding member 55 is located in the arc hole 536.

[0128] If the foldable baby bed needs to be folded, the operating member 21 is turned outward, and the operating member 21 drives the locking tongue 51 to move in a direction away from the locking plug 52 through the first pulling member 22, that is, driven by the first pulling member 22, the sliding member 55 slides from the limiting hole 535 to the arc hole 536, and moves in the arc hole 536 in a direction away from the limiting hole 535. In this way, when the sliding member 55 slides in the arc hole 536, on the one hand, the first lock assembly 50 can be switched from the locked state to the unlocked state, and on the other hand, the second end of the first rod 31 can be driven to rotate downward.

[0129] If the foldable baby bed needs to be unfolded, the sliding member 55 moves in the arc hole 536 towards the direction close to the limiting hole 535 until the sliding member 55 slides into the limiting hole 535. The hole wall of the limiting hole 535 limits the sliding member 55, so that the locking tongue 51 is fixed relative to the shell 53, and the locking plug 52 overlaps the locking tongue 51, so that the surrounding rod assembly 30 is fixed relative to the side frame 10.

[0130] In addition, with the cooperation between the arc hole 536 and the sliding member 55, the movement of the sliding member 55 is guided, the stability of the movement of the sliding member 55 is improved, and the smoothness of the unfolding and folding of the foldable baby bed is ensured.

[0131] Furthermore, combined with Fig.12The arc hole 536 takes the first connecting hole 538 as the center. In this way, the first rod 31 rotates with the first connecting hole 538 as the center, avoiding the arc hole 536 from interfering with the rotation of the first rod 31, thereby ensuring the smoothness of the rotation of the first rod 31.

[0132] Combination Fig.13 and Fig.14 The first lock assembly 50 further includes a second elastic reset member 56. The second elastic reset member 56 is connected to the lock tongue 51 and the first rod 31, and the second elastic reset member 56 is retracted along the length direction of the first rod 31, and the second elastic reset member 56 is used to drive the lock tongue 51 to move toward the direction close to the lock plug 52.

[0133] Combination Fig.15 During the unlocking operation, the operating member 21 is flipped outward, and the operating member 21 drives the lock tongue 51 to move away from the lock plug 52 through the first traction member 22, and the second elastic reset member 56 is gradually compressed.

[0134] It is understandable that when the external force acting on the operating member 21 is removed, the second elastic return member 56 gradually stretches, and under the action of the restoring force of the second elastic return member 56 , the locking tongue 51 extends outward from the first rod member 31 .

[0135] Optionally, the second elastic return member 56 is a spring, an elastic column, etc., but is not limited thereto.

[0136] Combination Fig.15 and Fig.16 When the first traction member 22 drives the lock tongue 51 to move in a direction away from the lock plug 52 so that the lock tongue 51 and the lock plug 52 are separated from each other, the first lock assembly 50 switches from a locked state to an unlocked state, and then the first rod member 21 and the second rod member 22 can rotate relative to the housing 53.

[0137] It should be noted that when the first lock assembly 50 and the second lock assembly 60 are in the unlocked state, the foldable baby crib can be folded under the action of some structural gravity of the crib itself, or by the user's squeezing force on the side frame 10 inward.

[0138] For example, combined with Fig.17When the first lock assembly 50 and the second lock assembly 60 are unlocked, the second end of the first rod 31 and the second end of the second rod 32 rotate downward under the action of self-gravity, so that the first end of the first rod 31 and the first end of the second rod 32 are folded toward the middle. At the same time, the second end of the third rod 41 and the second end of the fourth rod 42 are turned upward at the folding joint 43, so that the first end of the third rod 41 and the first end of the fourth rod 42 are folded toward the middle. Based on this, during the folding process, the first side frame 10a and the second side frame 10b are close to each other. In this way, the folding of the foldable baby bed as a whole can be achieved, which is conducive to reducing the volume of the foldable baby bed and reducing the space required for storing the foldable baby bed. In addition, the folding steps of the foldable baby bed can be simplified and the folding efficiency can be improved.

[0139] Combination Fig.18 When the foldable baby crib is fully folded, the first side frame 10a and the second side frame 10b are attached to each other.

[0140] In some embodiments, an elastic member may be provided to provide power for folding the foldable crib, thereby making the folding operation easier. There are many possibilities for the arrangement of the elastic member, as long as the elastic force of the elastic member can provide power for folding the surrounding rod assembly 30 or the supporting assembly after the first lock assembly 50 and the second lock assembly 60 are unlocked.

[0141] For example, combined with Fig.11 In some embodiments, the first lock assembly 50 further includes a first folding elastic member 57. One end of the first folding elastic member 57 is connected to the housing 53, and the other end of the first folding elastic member 57 is connected to the first rod 31 and / or the second rod 32. When the first lock assembly 50 is unlocked, the first folding elastic member 57 is used to drive the second end of the first rod 31 and / or the second rod 32 to rotate downward. In this way, the surrounding rod assembly 30 can be quickly folded by utilizing the self-weight of the first rod 31 and the second rod 32 and the elastic force of the first folding elastic member 57, thereby improving the folding efficiency.

[0142] Optionally, the first retractable elastic member 57 is provided with one end. One end of the first retractable elastic member 57 is connected to the housing 53, and the other end of the first retractable elastic member 57 is connected to the first rod 31; or one end of the first retractable elastic member 57 is connected to the housing 53, and the other end of the first retractable elastic member 57 is connected to the second rod 32, so that the first retractable elastic member 57 and the sliding member 55 can avoid motion interference.

[0143] Optionally, two first folding elastic members 57 are provided. Two ends of one first folding elastic member 57 are respectively connected to the first rod 31 and the housing 53, and two ends of another first folding elastic member 57 are respectively connected to the second rod 32 and the housing 53. In this way, the folding efficiency can be further improved.

[0144] For example, combining Figure 1 and Figure 2 The foldable baby crib includes a second folding elastic member 70. When the first locking assembly 50 and the second locking assembly 60 are unlocked, the second folding elastic member 70 is used to drive the third rod 41 to rotate relative to the first side frame 10a, thereby improving the folding efficiency.

[0145] The second retractable elastic member 70 includes but is not limited to structures such as a spring and an elastic rope.

[0146] Recombination Fig.11 The foldable baby bed also includes a mattress 80. The mattress 80 is arranged on the support assembly 40. When in use, the infant is placed on the mattress 80, and the mattress 80 supports the infant.

[0147] Optionally, combined Fig.11 The mattress 80 includes a first cushion body 81 and a second cushion body 82 .

[0148] The first cushion body 81 and the second cushion body 82 can both be hard cushion bodies. The first cushion body 81 is disposed between the first side frame 10a and the folding joint 43, and the second cushion body 82 is disposed between the second side frame 10b and the folding joint 43. The first cushion body 81 and the second cushion body 82 can be foldably connected.

[0149] Optionally, the first cushion body 81 is connected to the second cushion body 82 by a soft fabric. In this way, when the foldable baby crib is folded, there is no need to disassemble the mattress 80, so that the mattress 80 can be folded together with the bed frame, simplifying the unfolding and folding steps of the foldable baby crib and improving the unfolding and folding efficiency of the foldable baby crib.

[0150] In some embodiments, in combination Figure 2 The mattress 80 includes a first cushion body 81 , a second cushion body 82 and a third cushion body 83 .

[0151] Among them, the first cushion body 81, the second cushion body 82 and the third cushion body 83 are all hard cushion bodies. The first cushion body 81 is arranged between the first side frame 10a and the folding joint 43, the second cushion body 82 is arranged between the second side frame 10b and the folding joint 43, and the third cushion body 83 is arranged corresponding to the folding joint 43. The first cushion body 81 is connected to the third cushion body 83 through a soft fabric, and the second cushion body 82 is connected to the third cushion body 83 through a soft fabric. In this way, when the foldable baby bed is folded, there is no need to disassemble the mattress 80, so that the mattress 80 can be folded together with the bed frame, simplifying the unfolding and folding steps of the foldable baby bed, and improving the unfolding and folding efficiency of the foldable baby bed.

[0152] In some embodiments, one end of the surrounding rod assembly 30 is movably connected to the first side frame 10a, and the other end of the surrounding rod assembly 30 is movably connected to the second side frame 10b. The surrounding rod assembly 30 can move along the height direction of the first side frame 10a and the second side frame 10b to achieve the lifting and lowering of the surrounding rod assembly 30. When in use, the surrounding rod assembly 30 can be pulled down, which makes it convenient to place an infant in the foldable crib, and also makes it convenient to take the infant out of the foldable crib. When the foldable crib is placed next to an adult, the surrounding rod assembly 30 can be pulled down to facilitate the adult to take care of the infant without getting up. In addition, under normal circumstances, the surrounding rod assembly 30 can be pulled up to ensure the safety of the infant.

[0153] One end of the support assembly 40 is movably connected to the first side frame 10a, and the other end of the support assembly 40 is movably connected to the second side frame 10b. When in use, the support assembly 40 can move along the height direction of the first side frame 10a and the second side frame 10b to achieve the lifting and lowering of the support assembly 40.

[0154] In some embodiments, the first side frame 10a and the second side frame 10b can be extended and retracted along their length direction. Specifically, the first support member 11 and the second support member 12 are telescopic rods, the first support member 11 can be extended and retracted along its length direction, and the second support member 12 can be extended and retracted along its length direction. When the foldable baby bed is folded and folded, the first support member 11 and the second support member 12 can be retracted to reduce the height of the foldable baby bed, so that the packaging and transportation space can be reduced without disassembling the foldable baby bed, and the transportation cost can be reduced.

[0155] It should be noted that the foldable baby crib can be supported on the ground by feet or by wheels.

[0156] Combination Fig.13 In some embodiments, the foldable baby crib further includes a synchronization mechanism 90. One end of the synchronization mechanism 90 is rotatably connected to the first side frame 10a, and the other end of the synchronization mechanism 90 is rotatably connected to the second side frame 10b. Figure 4 For example, the left side structure and the right side structure of the first lock assembly 50 can maintain synchronization and consistency when they are unfolded and folded.

[0157] Furthermore, combined with Figures 13 to 15The synchronization mechanism 90 includes a fifth rod 91, a synchronization wheel set 93 and a sixth rod 92. The first end of the fifth rod 91 is rotatably connected to the first side frame 10a, and the first end of the sixth rod 92 is rotatably connected to the second side frame 10b. The synchronization wheel set 93 is rotatably disposed in the housing 53, and the synchronization wheel set 93 is disposed at the second end of the fifth rod 91 and the second end of the sixth rod 92. In this way, the synchronization wheel set 93 has a degree of rotational freedom and rotates smoothly. In the process of unfolding and folding the surrounding rod assembly 30 and the support assembly 40, the synchronization wheel set 93 plays a role in keeping the surrounding rod assembly 30 and the support assembly 40 synchronous, avoiding asynchronous action that affects the unfolding and folding effect.

[0158] Optionally, combined Fig.16 and Fig.19 The synchronous gear set 93 includes a first fixed gear 931, a first movable gear 932, a second fixed gear 933 and a second movable gear 934. The first fixed gear 931 is disposed at the second end of the fifth rod 91, the second fixed gear 933 is disposed at the second end of the sixth rod 92, the first movable gear 932 and the second movable gear 934 are located between the first fixed gear 931 and the second fixed gear 933, and are rotatably connected to the housing 53, the first fixed gear 931 is meshed with the first movable gear 932, the first movable gear 932 is meshed with the second movable gear 934, and the second movable gear 934 is meshed with the second fixed gear 933.

[0159] Of course, in another embodiment, the synchronous wheel set 93 may also be a synchronous belt wheel, but is not limited thereto.
