Pressure relief type automobile front bumper

Abstract

The pressure relief type automobile front bumper comprises a connecting plate fixedly connected with an automobile body front longitudinal beam, a guide column is fixedly arranged on the outer side of the connecting plate, a fixing cylinder is arranged on the outer side of the guide column, and a cross beam is fixedly installed at the end of the fixing cylinder; the two first anti-collision plates are arranged on the outer side of the cross beam; the connecting ball is fixedly mounted on the surface of the cross beam and is used for positioning the first anti-collision plate and the second anti-collision plate; the supporting piece is fixedly arranged on the outer side of the cross beam; the water bag is arranged on the inner side of the fixed cylinder; the mixing cavity is formed in the inner side of the cross beam. According to the pressure relief type automobile front bumper, multi-stage buffering and protection can be conducted on collision, the stress area in the collision process can be automatically increased, the collision strength can be automatically reduced, secondary damage to collided objects or people is effectively avoided, meanwhile, the structural strength of the cross beam can be further improved in the collision process, the cross beam is prevented from invading a cabin, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a pressure relief type automobile front bumper. Background technique [0002] Automobile is an important means of modern transportation. With the rapid development of society and the improvement of people's economic living standards, the automobile industry has developed rapidly in recent years. At the same time, people pay more attention to the safety level of automobiles, and bumpers are an important part of automobile safety design. Parts, wherein the protection requirements of the front bumper are higher, which can effectively improve the strength of the vehicle body, realize buffering during impact, thereby reducing the degree of vehicle collision, but there are still some deficiencies in the existing front bumper of the car. [0003] For example, the publication number is CN113734084A, a novel light-body automobile bumper, which provides grooves on the rear end sur...
