The role of the car bumper is very important. It has the functions of safety protection, vehicle decoration and improvement of the aerodynamic characteristics of the vehicle. From the perspective of safety, the car can play a buffering role in the event of a low-speed collision, protecting the front and rear bodies, and can play a certain role in protecting pedestrians in the event of an accident with pedestrians. The car bumper not only has the function of safety protection and protection of the body, but also can absorb and mitigate external impact.
The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact, protect the body and protect the body and occupant safety functions. From the appearance, the bumper is decorative and has become an important component for decorating the appearance of the car; at the same time, the car bumper also has a certain aerodynamic effect. The car bumper can improve the aerodynamic characteristics of the vehicle and make the vehicle more stable during driving.
In order to reduce the damage to the occupants in the event of a side collision, a door bumper is usually installed on the car to enhance the anti-collision impact of the door. This method is practical and simple, and does not change the body structure much, and has been widely promoted and used. What are the uses of the bumper? The car bumper can disperse the impact force. When the vehicle collides, the bumper can disperse the impact force to the energy absorption boxes on both sides and transmit it to the left and right front longitudinal beams, and then to other structures of the car body.
At the same time, the car bumper can also protect pedestrians. I used to see some vehicles with foam bumpers on the Internet, and I thought it was a shoddy work. In fact, changing to a plastic and foam bumper can alleviate the impact force on the legs of pedestrians, especially the calves, and with the reasonable design of the front bumper, it can reduce the degree of injury to pedestrians when they are hit. If the bumper is really bad, it will cause great damage to the parts of the car. Therefore, the car bumper can not only protect the vehicle, but also protect pedestrians and reduce the damage to pedestrians caused by accidents.
