Automobile collision energy dissipation protection device

Abstract

The invention discloses an automobile collision energy dissipation protection device, and belongs to the field of automobile protection devices. In order to solve the problem that the energy absorption effect is not ideal because a pure shearing mode is adopted in energy dissipation of the conventional safety protector, the protection device disclosed by the invention comprises a front template and a rear template, wherein at least one box-type energy absorption device capable of shearing crushing energy dissipation is arranged between the front template and the rear template. The conventional pure shearing energy dissipation in the prior art is changed into crushing deformation energy dissipation of a thin-wall box-type structure, so that a running automobile can immediately realize automatic shutdown after collision, comprehensive automatic vibration absorption can be simultaneously performed, the impact force of the automobile can be relieved or eliminated, the energy dissipation effect is remarkably improved, comprehensive protection of safety of the automobile and the personnel is realized, and the safety of the automobile and the personnel can be effectively protected at rear collision.

Description

technical field [0001] The invention relates to the field of automobile protection devices, in particular to an automobile collision energy dissipation protection device. . Background technique [0002] Automobile is the most common means of transportation in the contemporary era, and it has gradually become popular among families and individuals. More and more vehicles are driving on the road, and there are more and more various traffic accidents that occur thereupon, especially car crashes. cause huge losses. [0003] In current cars, especially freight cars, the usual practice is to install a bumper in front of the front of the car, but the bumper is rigidly connected to the car body as a whole. cause damage to the vehicle body, and may also cause casualties. [0004] Chinese patent CN200710034498.3 discloses a smart car safety protector, which can overcome the above-mentioned problems to a certain extent, but the energy dissipation part of the protector adopts a pure...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the problem that the existing safety protector adopts a pure shearing method for energy dissipation, and the energy absorption effect is not ideal, the present invention aims to provide an energy dissipation protection device for automobile collision, which combines the existing pure shearing protection device The shear energy dissipation is changed to a thin-walled box-shaped structure for crushing and deformation energy dissipation, and the energy dissipation effect can be significantly improved. In the event of a collision, whether it is a front collision or a rear collision, it can fully absorb the shock, ease the impact force or eliminate other impacts. The effect of the impact force can automatically turn off the engine when it hits the front, so that the safety of the car and people can be fully protected
