Shock absorber bumper Honda safety device and protection function

- Jul 02, 2019-

The shock absorber bumper Honda absorbs the external impact force when it is used. It protects the front and rear safety devices of the vehicle body. The materials used in the production are mainly metal materials, and are stamped with steel plates with a thickness of 3 mm or more. U-shaped channel steel, surface-treated chrome-plated, riveted or welded with the frame rails, and has a large gap with the body, as if it is an attached component. With the development of the automotive industry, car bumpers have become an important safety device and are on the road to innovation.


In addition to maintaining the original protection function, the front and rear shock absorber bumpers of the car must pursue harmony and unity with the car body shape, and pursue its own lightweight. In order to achieve this goal, the front and rear bumpers of the car use plastic, which is called plastic bumper. The plastic bumper is composed of three parts: outer plate, cushioning material and beam. The outer plate and the cushioning material are made of plastic, and the beam is stamped into a U-shaped groove by a cold-rolled sheet having a thickness of about 1.5 mm.


The outer plate and the cushioning material are attached to the beam, and the beam is screwed to the frame longitudinal beam and can be removed at any time. Plastics used in such plastic bumpers are generally made of two types of polyester and polypropylene materials by injection molding. There is also a kind of plastic called polycarbonate in foreign countries. It is infiltrated into the alloy composition and is alloy injection molding. The processed bumper not only has high strength rigidity, but also has the advantage of being weldable, and the coating performance is good. The use of cars is increasing.
