What is the difference between a car crash beam and a bumper?
The collision beam is generally hidden inside the bumper and inside the door, under the influence of a larger impact, the elastic material has been unable to buffer energy, the real role in the protection of the occupants of the car. Anti-collision beam is not every car has, it is mostly metal materials, such as aluminum, steel and the like. Now more and more manufacturers will be side door anti-collision beam into the car side door, side door anti-collision beam is also called the door anti-collision beam, refers to the internal structure of the door with beams, to strengthen the vehicle side of the structure. Based on the probability of side impact, the door anti-collision as an additional energy protection, can reduce the crew may suffer from external forces. Facts have proved that the door anti-collision beam in the vehicle hit fixed objects (such as trees) when the protection effect is very obvious. Especially in the low-speed collision accident, there is no collision-resistant steel beam will be a direct damage to the vehicle parts.
Bumper are generally plastic or resin and other high elasticity, to slow down the impact of a slight collision on the car. Anti-collision steel beams are generally hidden inside the bumper and inside the door, under the influence of a larger impact, the elastic material has been unable to buffer the energy, the real role in the protection of the occupants of the car.
The anti-collision beam is used to strengthen the structure of the vehicle, thereby improving the anti-collision resistance of the side impact to enhance the safety of the side. Protect the car staff, protect the engine and other major components. Car front and rear anti-collision beam, we generally row behind the bumper, side collision beam is generally arranged in the interior of the door structure.
Bumper and anti-collision beam is not the same thing. As the first barrier to passive safety of the car, the bumper is an important safety device for absorbing and mitigating external shocks and protecting the front and rear of the car. General cars are basically bumper, distributed in the front and rear front, mostly by the plastic, resin and other materials made of high elasticity, especially the production of the inside are containing silk, etc., and deputy factory production is not these things , Elastic greatly reduced. Bumper is mainly used to slow down the impact of a slight collision on the car, even if the crash is also easier to replace.
