Vehicle front bumper system

Abstract

The invention discloses a vehicle front bumper system, which comprises a front bumper skin (1), a front bumper beam (3) and an inflatable air bag (2) arranged between the front bumper skin (1) and the front bumper beam (3). The inflatable air bag (2) is provided with a bandage (5); the inflatable air bag (2) is connected with the front bumper beam (3) through the bandage (5); an inflation hole (4) is formed on the inflatable air bag (2); and the shape and internal pressure of the inflatable air bag (2) are controlled by controlling air inflated through the inflation hole (4). In the vehicle front bumper system, the inflatable air bag is arranged in the front bumper system instead of the traditional foam material, the shape and the internal pressure of the air bag are adjusted so as to reduce the rigidity of the front bumper system and enhance protection on the pedestrian during human-vehicle collision; and meanwhile, the inflatable air bag is superior to foam in the buffering and shock absorption abilities, thus the damage of the front bumper system and the components of the vehicle body during collision can be lessened, and the maintenance cost is effectively reduced.

Description

technical field [0001] The invention belongs to the field of vehicle components, and in particular relates to a vehicle front protection system. Background technique [0002] In recent years, with the development and expansion of the automobile market, the number of domestic automobiles has increased dramatically, and the probability of traffic accidents has also increased significantly. How to reduce the damage of traffic accidents and reduce the maintenance costs of vehicles after accidents has become a concern focus. At present, the front protection system of a vehicle is composed of a front protection anti-collision beam, a front protection foam and a front protection skin. When a vehicle collides with an accident, the external force is transmitted to the front bumper beam and the car body structure through the front bumper skin and the front bumper foam. Due to the external force, the front bumper skin is easily damaged, and the condenser is squeezed and damaged. In se...

AI Technical Summary

Problems solved by technology

When a vehicle collides with an accident, the external force is transmitted to the front bumper beam and the car body structure through the front bumper skin and the front bumper foam. Due to the external force, the front bumper skin is easily damaged, and the condenser is squeezed and damaged. In severe cases, it will Cause the deformation of the car body and the injury of the occupants. When a pedestrian collides, due to the high rigidity of the front protection system, the damage to the pedestrian's legs is also great.
