What is a car bumper? What does it do?
For the car owners, the bumper and the crash beam are all very familiar, but some drivers may not know the difference between the two or confuse the role of the two. As the most front-end protection of the car, the bumper and the crash beam both play a very important role.
First, anti-collision beam
Anti-collision beam is also called anti-collision steel beam, which is used to reduce the absorption of collision energy when the vehicle is affected by the collision of a device, composed of the main beam, energy absorption box, connected to the installation plate of the car, the main beam, energy absorption box can effectively absorb the collision energy when the vehicle occurs low-speed collision, as far as possible to reduce the impact force damage to the body rail, through this it plays a protective role on the vehicle. Anti-collision beams are generally hidden inside the bumper and inside the door. Under the effect of greater impact, elastic materials can not buffer energy, and really play a role in protecting the occupants of the car. Not every car has the anti-collision beam, it is mostly metal material, such as aluminum alloy, steel pipe and so on.
Two, bumper
Bumper is an important safety device to absorb and mitigate the external impact force and protect the front and back of the body. Generally in the front of the car, distributed in the front and rear front end, mostly made of plastic, resin and other elastic materials, especially the factory production inside contains silk, etc., bumper is mainly used to slow the impact of minor collisions on the car, even if the crash is relatively easy to replace. General bumper is ABS engineering plastic, using computer painting process, multi-layer spraying surface, line into a matte face, mirror effect, no brown no rust, more fit the body, in the protection of the car at the same time also increase the texture of the front face tail.
