On the surface, they are designed to avoid the impact of external damage on the vehicle safety system. They have the ability to reduce the injury of drivers and passengers during high-speed collisions. Now more and more are designed for pedestrian protection. The bumper is divided into a front bumper and a rear bumper. Its function is to reduce the impact force, absorb the energy of the collision, reduce the damage of the car, and ensure the safety of the occupants when the car is accidentally impacted at a low speed in the front and rear directions.
But the function of the bumper is limited. When subjected to a high-speed collision, it can only absorb a small part of the energy, and it cannot be used for insurance. It can only play a buffering role in the event of a vehicle collision and protect the front and rear bodies. The front and rear bumpers are mainly made of metal materials, plastics, glass fiber reinforced plastics, etc. Some bumpers are equipped with hydraulic cylinders inside to absorb more impact energy. Modern car bumpers are generally injection molded with rigid polyurethane plastics.
Many bumpers have grainy textures on the outer surface, which look leathery. There are also turn signals and fog lights on the bumpers.
