Abstract

The invention discloses a large freight vehicle tail anti-impact device which comprises a front face impact board. An oblique board is arranged at the upper end of the front face impact board. A height adjusting mechanism fixed to the tail end of a vehicle girder is arranged on the inner side of the oblique board. A connecting frame is arranged on the inner wall face of the front face impact board. A limiting buffering mechanism located on the two sides of the tail of the vehicle girder is hinged to the two ends of the connecting frame and located on the inner side of the height adjusting mechanism. The limiting buffering mechanism comprises two bases fixed to the vehicle girder. A horizontal guide rod is arranged between the two bases and sleeved with a horizontal sliding seat. The horizontal sliding seat is hinged to the connecting frame. A buffer spring is further arranged on the side face of the horizontal sliding seat, wherein the horizontal guide rod is sleeved with the buffer spring. The large freight vehicle tail anti-impact device has the beneficial effects that the safety protection performance can be improved.

Description

technical field [0001] The invention relates to a vehicle anti-collision device, in particular to a rear-end anti-collision device of a large freight vehicle. Background technique [0002] Since the chassis of a large freight vehicle is relatively high, and the overall height of a car is relatively low, when a car collides with a large truck, the front of the car is easily stuck at the rear of the truck and cannot move. In order to overcome this problem, large truck manufacturers generally install a fixed-structure anti-collision bumper at the rear of the large truck, which will result in a weak buffering capacity of the bumper, and the bumper will cause secondary damage to the vehicle. Therefore, the prior art has the problem of weak safety protection performance. Contents of the invention [0003] The object of the present invention is to provide an anti-collision device for the tail of a large freight vehicle. The invention has the characteristics of being able to imp...
