In the projection of the third direction Z, the fifth hinge shaft 75 is not coincident with the first hinge shaft 71, the sixth hinge shaft 76 is not coincident with the third hinge shaft 73, the seventh hinge shaft 77 is not coincident with the second hinge shaft 72, and the eighth hinge shaft 78 is not coincident with the fourth hinge shaft 74.

[0057] Further, the fifth hinge shaft 75 and the seventh hinge shaft 77 are respectively located at opposite sides of the first mounting base 11 in the second direction Y, i.e. the first hinge shaft 71 and the third hinge shaft 73 are located between the fifth hinge shaft 75 and the seventh hinge shaft 77. The sixth hinge shaft 76 and the eighth hinge shaft 78 are respectively located at opposite sides of the second mounting base 12 in the second direction Y, i.e. the third hinge shaft 73 and the fourth hinge shaft 74 are located between the sixth hinge shaft 76 and the eighth hinge shaft 78.

[0058] In this way, when the first support member 20 rotates around the first mounting base 11, the second support member 30 can be driven to rotate around the second mounting base 12 by the first connecting member 40, and the rotation directions of the corresponding first support member 20 and the second support member 30 are consistent.

[0059] Further, in the projection of the third direction Z, the first support member A 21 is located in the region from 6 o'clock to 12 o'clock, and the first support member B 22 is located in the region from 0 o'clock to 6 o'clock. When the two first support members 20 are in the folded state, the two first support members 20 are both directed to the 12 o'clock direction. When the two first support members 20 are switched from the folded state to the unfolded state, the first support member A 21 rotates counterclockwise, the first support member B 22 rotates clockwise, and the two first support members 20 move away from each other to form an included angle a.

[0060] Exemplarily, the second connecting member 50 comprises a second connecting member A 51 and a second connecting member B 52.

[0061] Further, the ninth hinge shaft 79 is located between the fifth hinge shaft 75 and the sixth hinge shaft 76, and the tenth hinge shaft 80 is located between the seventh hinge shaft 77 and the eighth hinge shaft 78.

[0062] It is to be noted that when all the second connecting member A 51 is connected to the first mounting base 11, all the second connecting member B 52 is also connected to the first mounting base 11; conversely, when all the second connecting member A 51 is connected to the second mounting base 12, all the second connecting member B 52 is also connected to the second mounting base 12.

[0063] Thus, when the two first supporting members 20 are in the unfolded state, the second connecting member 50 can support the first connecting member 40 and share part of the load of the first connecting member 40; when the two first supporting members 20 are switched between the unfolded state and the folded state, the second connecting member 50 can assist the first supporting member 20 or the second supporting member 30 to rotate. Exemplarily, the second connecting member 50 is connected to the second mounting base 12, when the two first supporting members 20 are switched from the unfolded state to the folded state, the first supporting member 20 applies a force to the first connecting member 40 along the first direction X away from the second mounting base 12, and the first connecting member 40 transmits part of the force to the second supporting member 30, so that the second supporting member 30 rotates about the second mounting base 12. At the same time, when the first connecting member 40 moves, one end of the second connecting member 50 moves away from the second mounting base 12, and the other end of the second connecting member 50 acts on the second mounting base 12, so that the second mounting base 12 moves away from the first mounting base 11. Thus, the second mounting base 12 and the second supporting member 30 have opposite movement tendencies, so that the second supporting member 30 is more easily rotated relative to the second mounting base 12.

[0064] In other embodiments, in the projection of the third direction Z, the first hinge shaft 71 coincides with the second hinge shaft 72.

[0065] Optionally, when the two first support members 20 are in the unfolded state, a≈180°, and the second support member 30 is parallel to the first support members 20. In this way, in the projection in the first direction X, the two first support members 20 and the first mounting base 11 form an upper rail structure with a larger range, and the height range of the baby is more compatible.

Figures 1 to 6 In this way, when the first support member 20 is subjected to an action force directed to the second support member 30 along the first direction X, the action force makes the hinged end of the first connecting member 40 with the first support member 20 have a tendency to approach the first mounting base 11, thereby making the first support member 20 have a tendency to approach the first mounting base 11, and the action force also makes the hinged end of the first connecting member 40 with the second support member 30 have a tendency to move away from the second mounting base 12, thereby making the second support member 30 have a tendency to move away from the second mounting base 12, and the length of the second connecting member 50 is constant, when the first connecting member 40 has a tendency to rotate, the second connecting member 50 acts on the second mounting base 12, in this way, the first connecting member 40 can distribute the action force to the first support member 20, the second support member 30 and the second connecting member 50.

[0067] As shown in FIG. 2, in the second embodiment, the second connecting member 50 connects the first connecting member 40 and the second mounting base 12, in the projection in the third direction Z, the first connecting member 40 is hinged with the first support member 20 through the fifth hinge shaft 75, the distance between the fifth hinge shaft 75 and the first mounting base 11 is L1, the first connecting member 40 is hinged with the second support member 30 through the sixth hinge shaft 76, the distance between the sixth hinge shaft 76 and the second mounting base 12 is L2, and L2

[0068] Figures 7 to 12 In this way, when the first support member 20 is subjected to an action force directed to the second support member 30 along the first direction X, the action force makes the hinged end of the first connecting member 40 with the first support member 20 have a tendency to approach the first mounting base 11, thereby making the first support member 20 have a tendency to approach the first mounting base 11, and the action force also makes the hinged end of the first connecting member 40 with the second support member 30 have a tendency to move away from the second mounting base 12, thereby making the second support member 30 have a tendency to move away from the second mounting base 12, and the length of the second connecting member 50 is constant, when the first connecting member 40 has a tendency to rotate, the second connecting member 50 acts on the second mounting base 12, in this way, the first connecting member 40 can distribute the action force to the first support member 20, the second support member 30 and the second connecting member 50.

[0069] ​Thus, when the first support 20 is subjected to an action force applied in the first direction X to the second support 30, the action force makes the hinged end of the first connecting piece 40 with the first support 20 have a tendency to move away from the first mounting base 11, and further makes the first support 20 have a tendency to move away from the first mounting base 11, and further makes the hinged end of the first connecting piece 40 with the second support 30 have a tendency to move close to the second mounting base 12, and further makes the second support 30 have a tendency to move close to the second mounting base 12, and the length of the second connecting piece 50 is fixed, when the first connecting piece 40 has a tendency to rotate, the second connecting piece 50 acts on the second mounting base 12, thus, the first connecting piece 40 can distribute the action force to the first support 20, the second support 30 and the second connecting piece 50.

[0070] Optionally, the sleeping basket further comprises a first handle 61, and the first handle 61 is mounted on the first mounting base 11.

[0071] Since the two first supports 20 are symmetrically arranged on the opposite sides of the first mounting base 11 in the second direction Y, and the first handle 61 is mounted on the first mounting base 11, the mounting position of the first handle 61 is close to the central position of the baby cradle in the second direction Y, and the sleeping basket can maintain balance when the user lifts the sleeping basket.

[0072] Optionally, the sleeping basket further comprises a second handle 62, and the second handle 62 is mounted on the side of the first support 20 away from the first mounting base 11 in the second direction Y.

[0073] Illustratively, the first support 20 is in a C shape, and the two ends of the first support 20 are respectively hinged to the first mounting base 11, and the second handle 62 is mounted on the middle part of the first support 20, thus, when the two first supports 20 are in the folded state, the second handle 62 is exposed to the outside, and it is easier for the user to grasp.

[0074] Optionally, the sleeping basket further comprises a buffer mounted on the side of the second support 30 away from the first support 20 in the first direction X.

[0075] Thus, when the sleeping basket is placed on a support surface such as the ground or a table top, the bottom buffer of the second support 30 can play a buffering role, absorb part of the impact, and improve the comfort of the baby.
