Abstract

The invention discloses a truck rear-end collision protection device, which comprises a fixed support frame, a spare wheel hanging mechanism, a spare wheel and a push rod, wherein the fixed support frame is fixedly arranged on a truck girder arranged at the bottom of a truck; the top of the spare wheel hanging mechanism is arranged on the fixed support frame; the axis part of the spare wheel is hung on the bottom of the spare wheel hanging mechanism; the upper end surface of the spare wheel is hinged onto the truck girder; one end of the push rod is connected with a truck rear bumper; the other end of the push rod is connected with the spare wheel hanging mechanism; and the push rod is used for driving the spare wheel to clockwise rotate around a hinging point of the spare wheel and the truck girder. The truck rear-end collision protection device has the advantages that when the rear-end collision occurs, the truck rear bumper is bent through being collided with a car; the push rod is driven to forwards move; the push rod drives the spare wheel hanging mechanism, so that the spare wheel clockwise rotates around the hinging point of the spare wheel and the truck girder; and when the car continuously advances, the spare wheel jacks the middle lower part of a car head of the car. The middle lower part of the car head of the car has high strength, and can bear greater impact force, so that the goal of preventing the car from entering the bottom of the truck through the spare wheel is achieved; and the car crash is avoided.

Description

technical field [0001] The invention relates to a rear-end protection device for trucks. Background technique [0002] At present, with the rapid development of highway traffic in our country, there are more and more automobile traffic accidents. Among them, 30% of serious accidents are caused by automobile rear-end collisions, and the consequences are very serious. The main reason why the car is easy to get into the bottom of the truck when it collides with the truck is that the truck frame at the bottom of the truck compartment is higher than the front of the car. Although the truck is equipped with a rear bumper, its protection against rear-end cars is very limited. There are two main reasons: one is that the rear bumper of the truck is too thin, which has a weak stop effect on the rear-end car; High, when a rear-end collision occurs, it cannot touch the front bumper of the car or the solid parts of the engine compartment of the car, and it cannot play the role of a sto...
