Car bumper definition
The car bumper is a safety device that absorbs and mitigates external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of the car were stamped into steel with steel plates, riveted or welded together with the frame rails, and there was a large gap between the car and the body, which looked very unattractive. With the development of the automotive industry and the extensive application of engineering plastics in the automotive industry, automotive bumpers have also entered the path of innovation as an important safety device. In addition to maintaining the original protection function, the front and rear bumpers of today's cars must pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The front and rear bumpers of the car are made of plastic and are known as plastic bumpers. The plastic bumper of a general automobile is composed of an outer panel, a cushioning material and a beam. The outer plate and the cushioning material are made of plastic, and the beam is punched with a cold-rolled sheet into a U-shaped groove; the outer plate and the cushioning material are attached to the beam.
