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...
