Problems solved by technology

[0005] After the vehicle collides, the front and rear bumpers of the car will transmit the collision force to the chassis. If the collision speed is high and the chassis is not strong enough, the chassis will deform and cause injuries to people in the car.

Embodiment Construction

[0034] A car collision protection device of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] An automobile collision protection device provided by the present invention mainly includes a bumper shell 1, an energy-absorbing buffer material 2, a bumper reinforcement beam 3, a friction column shell 4, a friction column 5, a fastening bolt 6, a spring 7, an ignition Device 8, sodium azide 9, filter 10.

[0036] The bumper shell 1 includes the front and rear bumper shells of the vehicle, and the present invention will be described for the sake of the previous bumper shells. Such as figure 1 As shown, the bumper shell 1 is generally integrated with the overall automobile shell and fixed on the frame of the automobile.

[0037] Such as Figure 2 ~ Figure 4 As shown, an energy-absorbing cushioning material body 2 is installed between the bumper shell 1 and the bumper reinforcing beam 3, and along t...

Abstract

The invention discloses an automobile collision protection device. An energy absorbing buffer material body is sandwiched between a bumper casing and a bumper reinforcing cross beam, a through hole is formed in the energy absorbing buffer material body, a cylindrical bulge is arranged on the inner side of the bumper casing, a metal sheet is pasted at the top end of the cylindrical bulge, a spring is arranged on the bumper reinforcing cross beam, a metal sheet is mounted at the top end of the spring as well, and when the bumper casing is not extruded, the two metal sheets are not contacted; a friction column casing is vertically arranged on the bumper reinforcing cross beam, a friction column and a gas generation structure are mounted in the friction column casing, and an igniter and the two metal sheets constitute a series circuit; when the series circuit is closed, the gas generation structure is subjected to a thermal decomposition reaction and presses the friction column to extend out of the friction column casing to contact with the ground. The device can transfer kinetic energy due to collisions to the ground, collision force is decomposed by the aid of friction between the friction column and the ground, and the device is an innovation of the whole automobile industry and has very great significance.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to an automobile collision protection device. Background technique [0002] According to the relevant laws of our country, a road traffic accident refers to an event of personal injury or property loss caused by a vehicle on the road due to fault or accident. A traffic accident generally has the following elements: 1. It is caused by a vehicle. Vehicles include motor vehicles and non-motor vehicles. Without vehicles, a traffic accident cannot be constituted; 2. It occurs on the road. The road refers to highways, urban roads and even In places under the jurisdiction of the unit but where social motor vehicles are allowed to pass, including squares, public parking lots and other places used for public passage; In the state of a complete stop, pedestrians voluntarily collide with vehicles, or accidents of crushing, falling, and casualties that occur during the process of passengers getting o...
