A self-destructing automobile bumper with protective function

Abstract

The invention discloses a self-destructive automobile bumper with a protective function, belonging to the field of automobile bumpers. Larger impact, the impact at this time will cause the shell to rupture and the prefabricated groove of the ball chain to rupture. The impact generated by the impact is absorbed by the rupture of the ball chain and the prefabricated groove, and the excavation of the pressure relief hole also provides a through hole for the buffer ball. Under the pressure of external force, the buffer ball can be sprayed out through the pressure relief hole to avoid the overall bursting of the pressure relief hole. At the same time, in the process of the pressure relief hole at the injection point of the buffer ball, the friction between the buffer ball and the protective ball head reduces the impact of the buffer ball spray. Speed, greatly reduce the possibility of accidental injury to pedestrians, can realize that in the process of low-speed driving of the car, when a collision with pedestrians occurs, the energy generated by the impact can be absorbed by the damage of the filler in the bumper, reducing the collision between the car and pedestrians. impact between.

Description

technical field [0001] The invention relates to the field of automobile bumpers, and more particularly, to a self-destructing automobile bumper with a protective function. Background technique [0002] A car bumper is a safety device that absorbs and slows down the external impact force and protects the front and rear parts of the body. Many years ago, the front and rear bumpers of automobiles were stamped into channel steel from steel plates, riveted or welded with the longitudinal beams of the frame, and had a large gap with the body, which looked very unsightly. With the development of the automobile industry and the large-scale 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 protective function, the front and rear bumpers of today's cars should also pursue harmony and unity with the body shape, and pursue their own lightweight. ...

AI Technical Summary

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.
