Embodiment Construction

[0026] A car collision energy dissipation protection device, such as figure 1 Shown, comprise two damping springs 5 ​​and two box-type energy-absorbing devices, be contained in the contact switch 2 on the front-end box-type energy-absorbing device. The rear template 4 is firmly connected on the front beam of the automobile, the front template 1 is firmly connected with the front bumper of the automobile, and the front end of the contact switch 2 is pushed against the push plate 3 connected with the front template 1. Once the car collides, the contact switch is immediately cut off by the impact of the push plate to realize flameout. The box-type energy-absorbing device is composed of a front connecting inner rail and a rear connecting outer rail. It adopts a box-shaped structure, and one set is installed on the left and right. The whole set of devices is installed one set at the front and rear of the car, so that the safety of the car and people can be fully protected when it ...

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...
