Car bumper function

The bumper has the functions of safety protection, decoration of the vehicle and improvement of the aerodynamic characteristics of the vehicle. From a safety point of view, the car can play a buffering role when a low-speed collision accident occurs, protecting the front and rear car bodies; it can play a certain role in protecting pedestrians when an accident occurs with a pedestrian. From the appearance point of view, it is decorative and has become an important part of decorating the appearance of a car; at the same time, the car bumper also has a certain aerodynamic effect.
At the same time, in order to reduce the damage to the occupants of the car in a side collision accident, door bumpers are usually installed on the car to enhance the impact force of the door. This method is practical and simple, with little modification to the body structure, and has been widely used. As early as the 1993 Shenzhen International Automobile Exhibition, the participating Honda Accord cut a part of a car door to reveal the door bumper to the audience to show its good safety performance.
The installation of door bumpers means that several high-strength steel beams are placed horizontally or obliquely in the door panel of each door, which acts as the front and rear bumpers of the car, so that the entire car has bumpers on the front, rear, left and right to "protect" , Forming a "copper wall and iron wall", so that the car occupants have a maximum safety area. Of course, installing this kind of door bumper will undoubtedly increase some costs for car manufacturers, but for car occupants, safety and sense of security will increase a lot.
