Self-damage type automobile bumper with protection function

Abstract

The invention discloses a self-damage type automobile bumper with a protection function, and belongs to the field of automobile bumpers. According to the self-damage type automobile bumper with the protection function, when an automobile running at a medium speed collides with pedestrians, large impact can be generated, and at the moment, the impact can cause breakage of a shell and breakage of aprefabricated groove of a ball chain, impact generated by impact is absorbed through breakage of the ball chain and the prefabricated groove, a through hole is also provided for the buffer ball through digging of the pressure relief hole, the buffer ball can be ejected out through the pressure relief hole under extrusion of external force, overall bursting of the pressure relief hole is avoided, and meanwhile in the process of the pressure relief hole in the ejection position of the buffer ball, friction between the buffering ball and the protection ball head reduces the spraying speed of thebuffering ball, the possibility of accidentally injuring pedestrians is greatly reduced, and energy generated by collision can be absorbed through damage of filler in the bumper in the medium-low-speed driving process of the automobile and when a collision accident with the pedestrians occurs, so that the impact force between the automobile and the pedestrians is reduced.

Description

technical field [0001] The invention relates to the field of automobile bumpers, in particular to a self-destructive automobile bumper with protective function. Background technique [0002] The car bumper is a safety device that absorbs and slows down external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of automobiles were stamped out of steel plates into channel steel, riveted or welded together with the frame longitudinal beams, and there was a large gap with the body, which looked very unattractive. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road of innovation. In addition to maintaining the original protection function, the front and rear bumpers of today's cars also pursue harmony and unity with the car body shape, and pursue their own lightweight. The front and...

Problems solved by technology

[0005] Traditional bumpers, which are located in most areas of the front and rear of the car, are apparently designed to avoid the impact of vehicle exterior damage on vehicle safety systems. They have the ability to reduce driver and occupant injuries during high-speed collisions, and are now increasingly Most of them are designed for pedestrian protection, and the buffer structure of the bumper is mostly aimed at the collision between high-speed cars and pedestrians. For cars running at low and medium speeds, the bumper can play a role in the collision with pedestrians. The cushioning effect is limited. Although cars traveling at medium and low speeds have limited damage to pedestrians, once a pedestrian fractures, it usually takes a long time to repair and recuperate, which will affect the normal life of pedestrians.
