Front bumper assembly

Abstract

The invention discloses a front bumper assembly, and belongs to the field of automobile bumpers. When an automobile collides with a foreign object, an anti-collision plate positioned on the outer sideis firstly impacted, and a compression spring between a mounting base and the anti-collision plate plays a first buffering role, so that the direct impact of the anti-collision plate on the mountingbase is reduced; meanwhile, a connecting rod can move towards the direction of the mounting base under the action of the anti-collision plate, buffer oil filled in a transition chamber is extruded into a connecting pipe and a buffer cavity through a sealing piston, the purpose of further buffering is achieved through compression of the buffer oil and a compression air bag, and the second bufferingeffect is achieved; and a bumper can be used for carrying out multiple protection on an automobile, meanwhile, a driver can conveniently observe the fatigue accumulation condition of the bumper, fatigue accumulation of the bumper which is not provided with obvious scratches on the surface but is impacted for multiple times can be found in time, and risks are reduced.

Description

technical field [0001] The invention relates to the field of automobile bumpers, in particular to a front bumper assembly. 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 rear bumpers of cars are made of plas...

Problems solved by technology

[0004] With the increase in the number of impacts on the bumper, even if there is no obvious crack defect on the outer surface of the bumper, fatigue will accumulate in the bumper, and the bumper will be more likely to break and fail under the next impact, and cannot play a protective role
