Therefore, when in use, the driving mechanism 45 is started to drive the swing arm 41 to flip down, so that the placement box 44 drops to a lower position, which is more conducive to loading and unloading.

[0053] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the driving mechanism 45 includes: a rack 451, which is movably connected to the longitudinal beam 3 and can move freely in the vertical direction. A half gear 411 is fixed to the end of the swing arm 41 and meshes with the rack 451. The swing arm 41 is flipped with the axis of the half gear 411 as the rotation axis, so that the rack 451 moves in the vertical direction. Under the meshing action, the rack 451 controls the flipping of the swing arm 41 through the half gear 411.

[0054] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the driving mechanism 45 also includes: a No. 1 guide plate 452, a No. 1 fixed plate 453, a threaded column 454 and a No. 1 driving motor 455.

The No. 1 driving motor 455 is fixed on the No. 1 fixed plate 453 to drive the threaded column 454 to rotate. Therefore, the No. 1 driving motor 455 is started to drive the threaded column 454 to rotate. Under the action of threaded screwing, the rack 451 is driven to move in the vertical direction through the No. 1 guide plate 452. Under the meshing action, the rack 451 controls the swing arm 41 to flip through the half gear 411.

[0055] It should be noted that, in addition to the above-mentioned driving scheme, the rack 451 can also be driven by other means, such as using an electric push rod to drive the rack 451 to move in the vertical direction.

[0056] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the driving mechanism 45 also includes: a No. 2 guide plate 456, a No. 2 fixed plate 457 and a guide column 458. The No. 2 guide plate 456 is fixed on the rack 451, the No. 2 fixed plate 457 is fixed on the longitudinal beam 3, the guide column 458 is fixed on the No. 2 fixed plate 457 and passes through the No. 2 guide plate 456, and a No. 1 limit plate 459 is fixed on the protruding end of the guide column 458. When the rack 451 moves in the vertical direction, it will drive the No. 2 guide plate 456 to move along the guide column 458, guide the rack 451, and improve the stability of the rack 451.

The No. 2 driving motor 8 is fixed on the mounting ear 421 with a hole to drive the mounting frame 43 to rotate. Therefore, a parallelogram structure is formed by the two swing arms 41, the mounting rod 42 and the rack 451. No matter what angle the two swing arms 41 are flipped to, the mounting rod 42 is always in a vertical state, that is, the opening of the placement box 44 is always facing upward, thereby ensuring the stability of cargo transportation. When loading and unloading is required, the No. 2 driving motor 8 is started to drive the mounting frame 43 to rotate, so that the placement box 44 is flipped to an inclined state, which is conducive to loading and unloading.

[0061] Preferably, by Figure 1 and Figure 6As shown, in this embodiment, it also includes: a connecting plate 431, an internal threaded tube 441 and a locking bolt 9.
