Automobile anti-rear-end-collision buffer device

Abstract

The invention provides an automobile anti-rear-end-collision buffer device. An anti-collision energy-releasing device is composed of a plurality of groups of electric extension devices and a plurality of groups of energy-releasing mechanisms, wherein the plurality of groups of electric extension devices and the plurality of groups of energy-releasing mechanisms are assembled on the tail portion of an automobile, one end of each electric extension device and one end of each energy-releasing mechanism are connected with the tail portion of the automobile, the other end of each electric extension device and the other end of each energy-releasing mechanism are the inner side of an automobile anti-collision safety-guard frame. A safety-guard frame rubber sheath wraps the outside of the automobile anti-collision safety-guard frame, and buffer rubber blocks are arranged on the outer side of the automobile anti-collision safety-guard frame. When the automobile runs at a high speed, and a rear-end-collision accident occurs suddenly, the automobile anti-rear-end-collision buffer device absorbs impact energy and releases the impact energy, the electric extension devices automatically extend out for a certain idle stroke at the same, and therefore the automobile anti-rear-end-collision buffer device guarantees that an automobile body cannot be damaged. The safety-guard frame rubber sheath which warps the outside of the automobile anti-collision safety-guard frame can prevent sparks from being generated in the process of collision and prevent explosion from happening.

Description

technical field [0001] The invention relates to the technical field of vehicle safety protection, in particular to an automobile anti-rear-collision buffer device for various special vehicles and vehicles for transporting dangerous goods. Background technique [0002] At present, the high and low speed automobiles produced in our country have safety airbag devices in the design room, but there is no anti-collision function designed for car sound. In particular, various special vehicles and dangerous goods transport vehicles have many dangerous accidents while driving, and there is no guarantee for driving safety devices. The front and rear bumpers and the car body are directly connected by brackets. When the car collides, most of the energy is often transmitted directly to the frame. Once a collision occurs, the car body will be greatly damaged, especially Vehicles transporting dangerous goods often explode. Contents of the invention [0003] The purpose of the present i...

[0002] At present, the high and low speed automobiles produced in our country have airbag devices in the design room, but there is no anti-collision function designed for car sound

In particular, various special vehicles and dangerous goods transport vehicles have many dangerous accidents during driving, and there is no guarantee of driving safety devices.

The front and rear bumpers and the car body are directly connected by brackets. When the car collides, most of the energy is often transmitted directly to the frame. Once a collision occurs, the car body will be greatly damaged, especially Hazardous goods transport vehicles tend to explode
