The door closing cylinder 241 and the lifting cylinder 242 are respectively disposed at both sides of the lifting arm 22.
In the present embodiment, the hydraulic tailgate base member 2 and the frame 3 are connected to form a vehicle-mounted function mechanism of a truck. As shown in fig. 1. The hydraulic tailgate base member 2 is mainly composed of 4 large components, namely, the loading platform component 21, the lifting arm 22, the frame component 23 and the hydraulic component 24, which are connected in order to perform core functions of bearing, transmitting force and moment, securing position and the like in the hydraulic tailgate of the truck, as shown in fig. 2. On the rack assembly 23, the lifting arm mounting seat plate 231, the lifting cylinder mounting plate 232 and the door closing cylinder mounting plate 233 are welded for mounting the lifting arm 22 and the door closing cylinder 241 and the lifting cylinder 242 of the hydraulic assembly 24, as shown in fig. 3.
