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

Abstract

The invention discloses a front bumper assembly, which belongs to the field of automobile bumpers. When a car collides with a foreign object, the anti-collision plate located on the outer side is first impacted, and the compression spring between the installation base and the anti-collision plate is activated. The first heavy buffering effect reduces the direct impact of the anti-collision plate on the installation base. At the same time, the connecting rod will move in the direction of the installation base under the action of the anti-collision plate, and the buffer filled in the transition chamber will be filled by the sealing piston. The oil is squeezed into the connecting pipe and the buffer cavity, and the compression of the buffer oil and the compressed air bag can further buffer the purpose and play the role of the second buffer, which can realize multiple protections for the car by using the bumper, and at the same time facilitate driving Operators can observe the fatigue accumulation of the bumper, even if the bumper has no obvious scars but has been hit many times, it can even find the fatigue accumulation and reduce the risk.

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...
