[0073] Further, the linkage of one of the first unlocking assemblies 70 is a first linkage 72, and the linkage of the other first unlocking assembly 70 is a second linkage 73. The first linkage 72 is connected with the first joint lock 50 and the first unlocking operation member 71 of one of the first unlocking assemblies 70, and the second linkage 73 is connected with the second joint lock 60 and the first unlocking operation member 71 of the other first unlocking assembly 70. When unlocking, the user acts on one of the first unlocking operation members 71, and the first unlocking operation member 71 drives the first linkage 72 connected therewith to act, and the first linkage 72 drives the first joint lock 50 to act, so that the first joint lock 50 is switched from the locked state to the unlocked state. The user acts on the other first unlocking operation member 71, and the first unlocking operation member 71 drives the second linkage 73 connected therewith to act, and the second linkage 73 drives the second joint lock 60 to act, so that the second joint lock 60 is switched from the locked state to the unlocked state. In this way, the unlocking of the first joint lock 50 and the second joint lock 60 can be realized, so that the baby crib can be folded, and the function of mistaken unlocking is also achieved, so as to avoid the baby crib from being mistakenly folded to cause the injury of the infant.

[0074] Of course, in other embodiments, the first unlocking assembly 70 can also be an electronic unlocking assembly, which is not limited in this regard.

[0075] In one embodiment, the first linkage 72 and the second linkage 73 are both linkage ropes. Of course, in other embodiments, the first linkage 72 and the second linkage 73 can also be other linkage structures, which are not limited in this regard.

[0076] Optionally, the linkage rope comprises 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 can move along the length direction of the protective sleeve relative to the protective sleeve. One end of the steel wire rope is connected with the first unlocking operating member 71, and the other end of the steel wire rope is connected with the joint lock. In this way, the steel wire rope plays a linkage role, and the protective sleeve plays a positioning role.

[0077] In one embodiment, referring to Figure 6 to Figure 9 The first joint lock 50 comprises a first lock tongue 52 and a first lock plug 53. The first lock tongue 52 is movably arranged at the second end of the first rod member 31 and connected with the first linkage member 72, and the first lock plug 53 is arranged at the second end of the second rod member 32.

[0078] In the locked state, the first lock plug 53 overlaps the first lock tongue 52, and the first linkage member 72 can drive the first lock tongue 52 to move away from the first lock plug 53, so as to switch the first joint lock 50 from the locked state to the unlocked state. In the unlocked state, the first lock tongue 52 is separated from the first lock plug 53.

[0079] When the baby bed is unfolded and the first joint lock 50 is in the locked state, the first rod member 31 and the second rod member 32 are coaxially arranged, and the first lock plug 53 overlaps the first lock tongue 52.

[0080] If the baby bed needs to be folded, the user can act on the first unlocking operating member 71, and the first unlocking operating member 71 drives the first lock tongue 52 to move away from the first lock plug 53 through the first linkage member 72, so that the first lock tongue 52 is separated from the second lock plug 63, and the first joint lock 50 is unlocked. Alternatively, the user can also act on the second unlocking operating member 81, and the second unlocking operating member 81 drives the first lock tongue 52 to move away from the first lock plug 53, so that the first lock tongue 52 is separated from the second lock plug 63, and the first joint lock 50 is unlocked. After the first joint lock 50 is unlocked, the second end of the first rod member 31 and the second end of the second rod member 32 move downward under the action of their own gravity, so that the first end of the first rod member 31 and the first end of the second rod member 32 are folded towards the middle.

[0081] In one embodiment, referring to Figure 3 The first joint lock 50 further comprises a first housing 51. The first housing 51 is sleeved on the second end of the first rod member 31 and the second end of the second rod member 32. The second end of the first rod member 31 and the second end of the second rod member 32 are both rotationally connected with the first housing 51.

[0082] In one embodiment, referring to Figure 3The first shell 51 is provided with a first limiting hole 515 and a first arc hole 516 in communication with the first limiting hole 515. The first limiting hole 515 is arranged corresponding to the position between the first rod member 31 and the second rod member 32, and the first arc hole 516 is arranged corresponding to the second end of the first rod member 31.

[0083] Further, referring to Figure 3 The first lock tongue 52 is provided with a first sliding member 522. When the first joint lock 50 is in the locked state, the first sliding member 522 is arranged in the first limiting hole 515. The first sliding member 522 can slide from the first limiting hole 515 into the first arc hole 516 and move in the first arc hole 516 away from the first limiting hole 515, so as to switch the first joint lock 50 from the locked state to the unlocked state. In the unlocked state, the first sliding member 522 is located in the first arc hole 516.

[0084] If the user needs to fold the crib, the user acts on the first unlocking operating member 71, and the first unlocking operating member 71 drives the first lock tongue 52 to move away from the first lock plug 53. Alternatively, the user can also act on the second unlocking operating member 81, and the second unlocking operating member 81 drives the first lock tongue 52 to move away from the first lock plug 53. In the process of moving the first lock tongue 52 away from the first lock plug 53, the first sliding member 522 slides from the first limiting hole 515 into the first arc hole 516 and moves in the first arc hole 516 away from the first limiting hole 515. In this way, when the first sliding member 522 slides in the first arc hole 516, on the one hand, the first joint lock 50 can be switched from the locked state to the unlocked state, and on the other hand, the second end of the first rod member 31 can be driven to rotate downward.

[0085] If the user needs to unfold the crib, the first sliding member 522 moves in the first arc hole 516 towards the first limiting hole 515 until the first sliding member 522 slides into the first limiting hole 515. The hole wall of the first limiting hole 515 limits the first sliding member 522, so that the first lock tongue 52 is fixed relative to the first shell 51, and at the same time, the first lock plug 53 is lapped on the first lock tongue 52, so that the first surrounding rod group 30 is fixed relative to the first side frame 10 and the second side frame 20.

[0086] In addition, under the cooperation of the first arc hole 516 and the first sliding member 522, the movement of the first sliding member 522 is guided, the stability of the movement of the first sliding member 522 is improved, and the smoothness of unfolding and folding the crib is ensured.

[0087] Further, the first arc hole 516 is centered at the connection position of the first shell 51 and the first rod member 31. In this way, the first rod member 31 rotates around the connection position of the first shell 51 and the first rod member 31, avoiding interference of the first arc hole 516 with the rotation of the first rod member 31, and ensuring smooth rotation of the first rod member 31.

[0088] In another embodiment, the first shell 51 is provided with a first insertion hole. The first joint lock 50 further comprises a first limiting member movably arranged in the first insertion hole, or the first limiting member is detachably arranged in the first insertion hole. The first lock tongue 52 is provided with a first limiting groove.

[0089] In the locked state, the first limiting member is in limiting cooperation with the first limiting groove to limit the movement of the first lock tongue 52 relative to the first rod member 31. In the unlocked state, the first limiting member is separated from the first limiting groove.

[0090] If the baby crib needs to be folded, the first limiting member is pulled outward to separate the first limiting member from the first limiting groove, thereby releasing the limiting of the first lock tongue 52.

[0091] If the baby crib needs to be unfolded, the first limiting member is pushed inward to limit the movement of the first lock tongue 52 relative to the first rod member 31, and the first lock block 53 is lapped on the first lock tongue 52, so that the first surrounding rod group 30 is fixed relative to the first side frame 10 and the second side frame 20.

The second unlocking operating member 81 is movably arranged in the first shell 51, and the second unlocking operating member 81 can move in a direction close to the first lock tongue 52 along the height direction of the first side frame 10 and the second side frame 20, so that the first connecting member 721 moves away from the first lock plug 53 under the abutment of the first inclined portion 811. When unlocking, the user pushes the second unlocking operating member 81 upwardly, so that the first connecting member 721 is in contact with the first inclined portion 811 and moves away from the first lock plug 53 under the action of the first inclined portion 811, thereby driving the first lock tongue 52 to move away from the first lock plug 53, and realizing the unlocking of the first joint lock 50.

[0097] In one embodiment, referring to Figure 8 and Figure 9 , the second joint lock 60 includes a second lock tongue 62 and a second lock plug 63. The second lock tongue 62 is movably arranged at the second end of the third rod member 41 and connected with the second linkage 73, and the second lock plug 63 is arranged at the second end of the fourth rod member 42.

[0098] In the locked state, the second lock plug 63 is overlapped on the second lock tongue 62, and the second linkage 73 can drive the second lock tongue 62 to move away from the second lock plug 63, so as to switch the second joint lock 60 from the locked state to the unlocked state. In the unlocked state, the second lock tongue 62 is separated from the second lock plug 63.

[0099] When the crib is unfolded and the second joint lock 60 is in the locked state, the third rod member 41 and the fourth rod member 42 are coaxially arranged, and the second lock plug 63 is overlapped on the second lock tongue 62.

[0100] If the crib needs to be folded, the user acts on the first unlocking operating member 71, and the first unlocking operating member 71 drives the second lock tongue 62 to move away from the second lock plug 63 through the second linkage 73, so that the second lock tongue 62 is separated from the second lock plug 63, and the second joint lock 60 is unlocked. Alternatively, the user can also act on the third unlocking operating member 91, and the third unlocking operating member 91 drives the second lock tongue 62 to move away from the second lock plug 63. After the second joint lock 60 is unlocked, the second end of the third rod member 41 and the second end of the fourth rod member 42 move downward under the action of their own gravity, so that the first end of the third rod member 41 and the first end of the fourth rod member 42 are folded towards the middle.

[0101] In one embodiment, referring to Figure 4 , the second joint lock 60 further includes a second housing 61. The second housing 61 is sleeved on the second end of the third rod member 41 and the second end of the fourth rod member 42. The second end of the third rod member 41 and the second end of the fourth rod member 42 are both rotationally connected with the second housing 61.

[0102] In one embodiment, referring to Figure 4 , the second housing 61 is provided with a second limiting hole 615 and a second arc hole 616 in communication with the second limiting hole 615.

The second sliding member 622 can slide from the second limiting hole 615 into the second arc hole 616 and move in the second arc hole 616 away from the second limiting hole 615, so as to switch the second joint lock 60 from the locked state to the unlocked state. In the unlocked state, the second sliding member 622 is located in the second arc hole 616.

[0104] If the crib needs to be folded, the first unlocking operating member 71 is used to drive the second locking tongue 62 to move away from the second locking block 63. Alternatively, the user acts on the third unlocking operating member 91, which drives the second locking tongue 62 to move away from the second locking block 63. In the process of moving the second locking tongue 62 away from the second locking block 63, the second sliding member 622 slides from the second limiting hole 615 into the second circular arc hole 616 and moves away from the second limiting hole 615 in the second circular arc hole 616. Thus, when the second sliding member 622 slides in the second circular arc hole 616, on the one hand, the second joint lock 60 can be switched from the locked state to the unlocked state, and on the other hand, the second end of the third rod member 41 can be driven to rotate downward.

[0105] If the crib needs to be unfolded, the second sliding member 622 moves in the second circular arc hole 616 towards the second limiting hole 615 until the second sliding member 622 slides into the second limiting hole 615. The hole wall of the second limiting hole 615 limits the second sliding member 622, so that the second locking tongue 62 is fixed relative to the second shell 61, and at the same time the second locking block 63 overlaps the second locking tongue 62, so that the second surrounding rod group 40 is fixed relative to the first side frame 10 and the second side frame 20.

[0106] In addition, the cooperation between the second circular arc hole 616 and the second sliding member 622 makes the movement of the second sliding member 622 have a guiding effect, improves the stability of the movement of the second sliding member 622, and ensures the smoothness of the unfolding and folding of the crib.

[0107] Further, the second circular arc hole 616 has the connection position of the second shell 61 and the third rod member 41 as the center. In this way, the third rod member 41 rotates around the connection position of the second shell 61 and the third rod member 41, avoiding interference of the second circular arc hole 616 with the rotation of the third rod member 41, and ensuring the smoothness of the rotation of the third rod member 41.
