The front and rearcar bumpers is the first time the vehicle is subjected to the impact force. An important concept in the passive safety of the vehicle body is that it is stressed by the whole body. To put it bluntly, a certain position of the car body has been hit. If only this part is to withstand the force, the protection effect will be poor. If the entire skeleton structure is subjected to force when subjected to a certain force, the strength of the force received by one point can be minimized, especially the front and rear anti-collision steel beams play a significant role here.
Doorcar bumperss These steel or aluminum structural components are mounted inside the door and are not visible from the outside. Some take a vertical layout, and some use a diagonal type, that is, extending from the bottom door frame to the bottom edge of the window glass. Regardless of its specific location, the door impact beam is designed as an additional energy-absorbing protective layer that reduces the external forces that the occupant may experience. It turns out that the protection effect of the door impact beam when the vehicle hits a fixed object (such as a tree) is very obvious.
The function of thecar bumpers is mainly used to reduce the maintenance cost in the middle and low speed collisions, and can reduce the damage to the members to a certain extent.
