[0034] like Figure 2 As shown, the vertical wall 3 includes an "L"-shaped side vertical plate 31 and a bottom horizontal plate 32. Specifically, the bottom plate 4, the side vertical plate 31 and the bottom horizontal plate 32 are all spliced into an inner frame by square tubes, and the outer side of the inner frame is covered with a thin metal plate or a wooden board by screws or welding; the power assembly box 5 is installed at the connection between the horizontal plate 32 and the vertical plate 31.
[0035] When the cargo needs to be loaded into the cargo box 1, the vertical wall 3 is first driven by the power assembly box 5 to move to the entrance of the rear box door 2; then, after the bottom cross plate 32 is filled with the cargo, the vertical wall 3 is driven to move a certain distance into the car; then, a bottom plate 4 is manually installed into the entrance of the rear box door 2 along the guide rail 12, and then the bottom plate 4 is filled with the cargo, and then the bottom plate 4 is moved into the car; the loading of the cargo is completed.
[0036] When the goods need to be unloaded from the cargo box 1, the vertical wall 3 is first driven to move out of the vehicle through the power assembly box 5, pushing the bottom plate 4 to move to the entrance of the rear box door 2; then, the goods on the bottom plate 4 are unloaded; finally, the goods on the bottom cross plate 32 are unloaded; and the unloading is completed.
[0037] Preferably, a flow-type conveying platform is provided outside the rear door 2 to receive and convey goods, saving time and effort. During the loading and unloading process, workers do not need to enter the vehicle to carry goods, thus avoiding damage to goods caused by the carrying and loading and unloading process; only one person is required to complete the loading and unloading, thus reducing operating costs and increasing loading and unloading efficiency.
[0038] like Figure 2 As shown, an oblique support rod 33 is arranged between the side vertical plate 31 and the bottom horizontal plate 32. The oblique support rod 33, the side vertical plate 31 and the bottom horizontal plate 32 form a stable triangular structure, which improves the overall stability of the vertical wall 3.
