Problems solved by technology

With the continuous development of the automobile industry, the speed of the car is getting faster and faster. The angle of the collision of the car is highly random. The traditional car bumper mainly deals with the frontal collision of the car. When it hits the bumper with a certain angle, The huge inertial force will cause serious deformation and serious damage to the head of the car, and the energy absorption effect is not ideal

Abstract

The invention relates to a car collision buffering device which comprises a foam arch plate (2), a bumper (2), a steel plate spring (31), spring link mechanism, a first energy absorption device (51),a second energy absorption device (52) and a mounting bottom plate (6). When a car collision happens, the foam arch plate receives energy deformation, a first buffering function is achieved; when energy generated by the collision is transferred to the bumper, the steel plate spring jacks the bumper, and a second buffering function is achieved on the bumper. The energy absorption devices are mounted behind the bumper, and a third buffering function is achieved. The car collision buffering device can bear collision force of the front end of the car in all directions, when the car is collided seriously, three times of buffering can be carried out, and the problem that a traditional car bumper is single in stress direction and not ideal in energy absorption effect is solved. The car collisioncapacity is improved, the collision speed is reduced, and higher safety guarantee is provided.

Description

technical field [0001] The invention provides an automobile collision buffer device, which belongs to the technical field of automobile protection devices. Background technique [0002] Automobiles have already become a closely related means of transportation in people's lives because of their convenience and speed. In recent years, with the improvement of people's living standards, the number of cars owned has continued to increase. However, traffic accidents of motor vehicles are also showing an increasing trend year by year. With the continuous development of the automobile industry, the speed of the car is getting faster and faster. The angle of the collision of the car is highly random. The traditional car bumper mainly deals with the frontal collision of the car. When it hits the bumper with a certain angle, The huge inertial force will cause serious deformation and serious damage to the head of the car, and the energy absorption effect is not ideal. The traditional...
