The groove walls of the bending groove sections 51 form supporting forces on the sliding parts 422 and the side plates 223, so that downward bending of the bottom plate 221 during placement of objects is avoided, the mechanical strength and stability of the second storage box 22 in the unfolded state are enhanced, and the placement of objects is facilitated. At this time, the first elastic member 53 is in a released state, under the downward gravity of the guiding slider 42, the first elastic member 53 is stretched, and under the condition that the elastic force of the first elastic member 53 and the gravity of the guiding slider 42 are balanced, the sliding portion 422 of the guiding slider 42 can be stably clamped in the bending slot section 51, so as to ensure the stability of the second storage box 22 in the unfolded state.

Optionally, the bending groove section 51 is further disposed near one end of the first storage box 21, so as to limit the sliding portion 422 when the second storage box 22 is switched to the folded state, so as to improve stability and safety in the folded state.

When the second storage box 22 is switched from the unfolded state to the folded state, an upward force is applied to the supporting portion 421, so that the first elastic piece 53 is compressed, and the supporting portion 421 is close to the limiting top wall 521, meanwhile, the supporting portion 421 can drive the sliding portion 422 to slide upwards along the bending groove section 51 to the guide rail main body 411, further, a force towards the direction of the first storage box 21 can be applied to the supporting portion 421 or the side plate 223, and the side plate 223 can move towards the right side wall 211 of the first storage box 21 under the driving of the sliding portion 422.

In addition, when the second storage box 22 is switched from the folded state to the unfolded state, since the first elastic member 53 is switched from the compressed state to the released state, the first elastic member 53 applies a downward elastic force to the supporting portion 421, and when the sliding portion 422 slides to the limiting end 412 along the guide rail groove 41 and moves toward the bending groove section 51, the supporting portion 421 is assisted to drive the sliding portion 422 to move downward along the bending groove section 51, so that time and labor are saved, and after the elastic force of the first elastic member 53 and the gravity of the guiding slider 42 are balanced, the sliding portion 422 is clamped in the bending groove section 51.

In some embodiments, the spacing assembly 50 further includes a second resilient member. The second elastic member is fixedly connected between the limiting bottom wall 522 and the supporting portion 421.

Alternatively, the natural length of the second elastic member is smaller than the natural length of the first elastic member 53. When the second storage box 22 is in the unfolded state, the first elastic member 53 is in the released state, the first elastic member 53 is stretched under the action of the downward gravity of the guide slider 42, and the sliding portion 422 of the guide slider 42 can be stably and lowly clamped in the bending groove section 51 under the condition that the elastic force of the first elastic member 53 and the gravity action of the guide slider 42 are balanced, at this time, the second elastic member is in the natural state. When the second magazine 22 is switched from the unfolded state to the folded state, the first elastic member 53 is compressed, and at the same time, the second elastic member is stretched to realize the upward movement of the sliding portion 422 along the bending groove section 51. When the second storage box 22 is switched from the folded state to the unfolded state, after the sliding part 422 slides into the bending groove section 51 of the limiting end 412 from the guide rail main body 411, the sliding part 422 moves downwards under the action of gravity and the tensile force of the second elastic piece, so that trouble and labor are saved. In addition, the second elastic member can also provide a buffer for the downward movement of the sliding portion 422 at this time, so as to avoid the sliding portion 422 from striking the limiting bottom wall 522, and prolong the service life of the limiting assembly 50.

In some embodiments, the stop assembly 50 further includes a stop aperture 55. The bottom end of the supporting portion 421 is provided with a positioning rod 423 extending in the height direction of the side plate 223, and the limiting hole 55 is provided in the limiting bottom wall 522. The positioning rod 423 is disposed through the limiting hole 523, and the positioning rod 423 moves up and down under the restriction of the limiting hole 55 when the first elastic member 53 is switched between the released state and the compressed state.

Optionally, the positioning rod 423 is disposed through the limiting hole 523, and when the second storage box 22 is switched from the unfolded state to the folded state, the positioning rod 423 can be pushed upward to move upward relative to the limiting hole 523, so that the first elastic member 53 is compressed, and the sliding portion 422 slides along the bending slot section 51 to the guide rail main body 411, so as to facilitate operation. When the second storage box 22 is switched from the folded state to the unfolded state, the positioning rod 423 can be pulled downwards to move downwards relative to the limiting hole 523 under the condition that the to-be-slid part 422 slides to the limiting end 412 along the guide rail main body 411, so that the first elastic piece 53 is stretched, and the to-be-slid part 422 slides to the guide rail main body 411 along the bending groove section 51; or the applied force can be removed, so that the supporting portion 421 spontaneously slides down along the bending groove section 51 under the self-gravity of the guide slider 42 and the elastic force of the first elastic member 53. During the downward movement of the supporting portion 421, the limiting bottom wall 522 can form a stopping effect on the bottom end of the supporting portion 421 to limit the downward displacement of the supporting portion 421.

When the second storage box 22 is in the unfolded state, the first torsion spring 24 is coaxial with the first rotating shaft 23, and the first torsion arm 242 and the second torsion arm 243 stretch the first spiral body 241. The first torsion arm 242 is located in the first limiting groove to limit the first torsion arm 242 in the circumferential direction so as to prevent the first torsion arm 242 from moving in the circumferential direction along the first direction; the second torsion arm 243 is located in the second limiting groove to circumferentially limit the second torsion arm 243 to prevent the second torsion arm 243 from moving circumferentially along the second direction.

When the second storage box 22 is switched from the unfolded state to the folded state, the first torsion spring 24 generates a reset trend under the reaction of the first torsion force, and the first torsion arm 242 and the second torsion arm 243 approach each other, so as to drive the first sub-panel 2221 and the second sub-panel 2222 to approach each other, which is beneficial to folding the front panel 222.
