[0032] like Figure 1 As shown, a pair of symmetrically distributed guide rails 205 are fixedly connected to the side wall of the lower housing 201, and the upper housing 202 slides with the guide rails 205. The guide rails 205 guide the upper housing 202 to slide and ensure the stability of the upper housing 202 during lifting, sliding and unfolding.

[0033] like Figures 1 to 3 As shown, the upper housing 202 is slidably fitted onto the outer side of the lower housing 201. The upper housing 202 provides a second layer of activity space for the user by lifting and unfolding.

[0034] The lower housing 201 and the upper housing 202 each have an entrance / exit on their respective sides. This allows users to easily access the spaces within the lower housing 201 and the upper housing 202 through these exits.

[0035] like Figure 4 As shown, each entrance and exit is hinged with a door 206, which is configured to cooperate with the entrance and exit. The opening and closing of the entrance and exit is controlled by the door 206.

[0036] like Figures 1 to 3 As shown, multiple sets of evenly distributed electric lifting rods 203 are fixedly mounted on the upper part of the frame 1, and the telescopic ends of the electric lifting rods 203 are all fixedly connected to the upper box body 202. The upper box body 202 is raised and lowered and unfolded by controlling the raising and lowering of the multiple sets of electric lifting rods 203.

[0037] Specifically, multiple sets of electric lifting rods 203 are evenly distributed at the four corners of the upper housing 202. By arranging multiple sets of electric lifting rods 203 at the four corners, the space occupied by the electric lifting rods 203 is reduced, and the space utilization rate of the lower housing 201 is improved.

[0038] like Figures 1 to 2 As shown, each of the multiple sets of electric lifting rods 203 is equipped with an inner rod 204. One end of the inner rod 204 located outside the electric lifting rod 203 is fixedly connected to the inner wall of the upper housing 202. The upper housing 202 is raised and lowered by controlling the raising and lowering extension of the inner rod 204, thereby facilitating the raising and lowering of the space inside the upper housing 202.

[0039] like Figures 3 to 4 As shown, the unfoldable box assembly 3 is fixedly assembled above the upper box 202. The unfoldable box assembly 3 includes an assembly base plate 301, which is fixedly assembled on the top surface of the upper box 202.
