[0042] An interlocking mechanism 3 is provided on the vehicle body 1 and connected to the drawer group 2. When any one of the plurality of storage drawers 211 is extended relative to the vehicle body 1, the interlocking mechanism 3 can lock the remaining storage drawers 211 in the vehicle body 1;

[0043] The interlocking mechanism 3 includes a plurality of locking claw members 10, a plurality of limiting links 4 and a movable connecting member 5. A plurality of the locking claw members 10 are arranged in the height direction of the vehicle body 1, and each locking claw member 10 is provided with a movable connecting member 5 connected to the storage drawer 211. The locking claw member 10 is used to clamp or release the storage drawer 211 so that the storage drawer 211 is locked or withdrawable; every two adjacent locking claw members 10 are connected by a limiting link 4. When a locking claw member 10 is opened, the locking claw member 10 will push the one / two limiting links 4 connected thereto to one side / both sides respectively, so that the other locking claw members 10 are limited by the limiting links 4.

[0044] The plurality of locking claw members 10 are sequentially arranged and distributed on the side of the vehicle body 1 along the height direction of the vehicle body 1 .

[0045] Specifically, in this example, the interlocking mechanism 3 limits the number of storage drawers 211 that can be pulled out, which can effectively reduce the total weight relative to the extension of the vehicle body 1, thereby effectively reducing the offset of the center of gravity of the vehicle body 1, and further achieving the effect of slowing down or preventing the tipping of the vehicle body 1. When a single storage drawer 211 is pulled out, the interlocking mechanism 3 locks the other storage drawers 211 in the vehicle body 1; the vehicle body 1 includes an inner frame and an outer frame, the interlocking mechanism 3 is arranged on the inner frame, and is located in the connection space between the inner frame and the outer frame, the outer side of the interlocking mechanism 3 is provided with a snap-fitting plate to snap it inside, and the outer side is provided with a hidden plate to hide it, and the outer side of the hidden plate is the outer frame of the vehicle body 1.
