Anti-collision device for truck rear

Abstract

The invention relates to the technical field of vehicle protection, and relates to an anti-collision device at the rear of a truck. The anti-collision device includes a slide rail, a slide block, a placement frame, a spare tire and a blocking rod. The slide rail is used to be fixed on the beam at the rear of the truck and arranged along the length direction of the truck; the slide block is arranged on the slide rail; One end of the retaining rod is rotatably connected with the girder; the retaining rod is used to be pushed and rotated by the placing frame when the slider slides forward, so that the other end touches the ground. According to the technical solution of the present invention, since the spare tire is a flexible part, the impact of the car can be buffered to reduce casualties; in addition, since the stop bar is against the ground after being hit, the stop bar can push the part of the car The impact force is transmitted to the ground, which can reduce the impact force of the car on the truck frame.

Description

technical field [0001] The invention relates to the technical field of vehicle protection, in particular to an anti-collision device at the rear of a truck. Background technique [0002] With the development of the economy and the increase of freight volume, truck transportation has increasingly become an irreplaceable mode of transportation. Due to the high chassis of the truck, the rigidity and strength of the cabin, and the shortness of the car, in an accident, the car can easily get under the body of the truck from the rear of the truck, causing the car to be directly squeezed and deformed by the frame of the truck or the floor of the cargo box, and even cutting, causing casualties. In order to prevent the car from rear-ending the truck and getting into the bottom of the truck, it is generally required to install an anti-collision device at the rear of the truck. [0003] Currently, if figure 1 As shown, the patent No. CN105015467A discloses a kind of anti-collision d...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned truck rear anti-collision device has at least the following defects: 1. When a rear-end collision occurs, the car hits the above-mentioned anti-collision device at high speed. Transfer to the beam 1 of the truck, which will cause greater damage to the beam 1 of the truck, and the maintenance cost is relatively high; -2 crashed, and now the inclined telescopic rod 3b is easily inserted into the compartment of the car and causes more serious personal injury, so it is urgent to solve this potential safety hazard.
