[0055] To ensure the safety of the tailgate after it is installed on the truck frame 1, the boarding plate of the tailgate is detachably connected to the anti-drop mounting plate 1211. Specifically, when the tailgate is in an unused folded state, the boarding plate is fixedly connected to the anti-drop mounting plate 1211 by a bolt assembly, so that the tailgate will not suddenly fall due to a fault even if the truck encounters bumps during driving, or the tailgate is prevented from suddenly unfolding and causing the tailgate to fall. When the user needs to use the tailgate, he only needs to disconnect the tailgate from the anti-drop mounting plate 1211 first, and the tailgate can be used normally, which effectively ensures the safety of the use of the tailgate, and the overall structure is practical and easy to disassemble and assemble. The specific working principle is: the power device 700 is started to drive the gear to rotate. At this time, the mounting assembly 600 can be moved on the guide rail 200 as a whole, and the tailgate in the folded state can be pushed out at this time. When the boarding plate assembly 900 is completely pushed out of the frame 1, the hydraulic device 800 adjusts the height of the boarding plate assembly 900 according to the actual height, and the user only needs to manually unfold the boarding plate assembly 900.

The specific principle is: when the power device 700 starts to drive the boarding board assembly 900 in a folded state to move and push out, the connecting plate 910 follows the movement and releases the connection relationship with the anti-drop mounting plate 1211. At this time, the boarding board assembly 900 is no longer constrained by the anti-drop bracket 121. When the boarding board assembly 900 is completely pushed out, it can be directly unfolded. When the user uses the tail board and folds the boarding board assembly 900 again, the power device 700 drives the boarding board assembly 900 to reset, and the anti-drop mounting plate 1211 is directly slidably engaged with the connecting plate 910, and finally the hoisting bracket 100 realizes the fixed storage of the boarding board assembly 900. The connection plate 910 and the anti-drop installation plate 1211 are detachably connected, and the user does not need to manually disassemble and assemble the tailgate when using it. The boarding board assembly 900 can automatically disassemble or connect the connection plate 910 and the anti-drop installation plate 1211 when moving, and the structure is simple and practical. At the same time, the connection surfaces of the connection plate 910 and the anti-drop installation plate 1211 are both flat, which can improve the connection stability of the connection plate 910 and the anti-drop installation plate 1211.

[0057] In addition, the spacing between the two relative groups of hoisting brackets 100 can be adjusted according to the width of the tailgate and the width of the truck frame 1, which significantly improves the versatility of the entire tailgate, and is easy to install and has low manufacturing cost.

[0058] The tailgate is fixed to the frame 1 of the truck through a lifting mechanism. Specifically, the lifting mechanism includes at least four lifting brackets 100, two lifting brackets 100 form a group and are fixed to the truck frame 1. Furthermore, the lifting bracket 100 includes a first bracket 110 and a second bracket 120 installed on the first bracket 110, wherein a first mounting groove 130 for placing the guide rail 200 is formed between the first bracket 110 and the second bracket 120, so that the guide rail 200 can be quickly positioned and installed, and the tailgate is installed on the guide rail 200 through the installation assembly 600.
