It only needs to be improved manually for some specific positions after the unfolding is completed, such as locking the rotating shaft mechanism, confirming waterproofing, locking the rear baffle 62, etc.

[0044] Specifically, in the present embodiment, the lifting device acts on the lifting part 21 provided on the top cover 3. Driven by the lifting device, when the top cover 3 is unfolded toward the outside of the main body 1 around the first rotating shaft mechanism, the top cover 3 rotates and unfolds toward the outside of the main body 1 around the first rotating shaft mechanism along the first direction 101, so that the side wall panel 4 is linked with the bottom plate 5 to move toward the ground around the fourth rotating shaft mechanism along the second direction 102, until the side wall panel 4 and the bottom plate 5 are unfolded 180 degrees relative to each other, the lifting device starts to move downward, and under the action of gravity and the linkage force, the bottom plate 5 is rotated toward the ground around the fourth rotating shaft mechanism along the second direction 102, so that the side wall panel 4 is linked with the top cover 3 to rotate toward the ground around the first rotating shaft mechanism along the second direction 102, until the bottom plate 5 is completely placed on the ground and the side wall panel 4 and the bottom plate 5 remain perpendicular to each other, that is, the unfolding of the auxiliary box 2 is completed; after the mechanized operation and unfolding, manual participation is required to lock the rotating shaft mechanism, perform waterproofing, etc.
