The role of the car bumper:
The car bumper has the functions of safety protection, decorating the vehicle and improving the aerodynamic characteristics of the vehicle. From the safety point of view, when a car has a low-speed collision accident, it can play a buffering role to protect the front and rear body; it can play a role in protecting pedestrians in the event of an accident with pedestrians. From the appearance, it is decorative and has become an important part of the decoration of the car. At the same time, the car bumper has a certain aerodynamic effect.
At the same time, in order to reduce the damage to the occupant when the car is in a side collision accident, 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 has little change to the structure of the vehicle body. It has been widely used. As early as the 1993 Shenzhen International Automobile Exhibition, the Honda Accord exhibited a part of the door to expose the door bumper to the audience to show its good safety performance.
Installing the door bumper is to erect or tilt several high-strength steel beams in the door panel of each door to play the role of the front bumper of the front and rear of the car. Car occupants have a maximum safety zone. Of course, installing such a door bumper will undoubtedly increase the cost for the car manufacturer, but for the occupants of the car, the safety and security will increase a lot.
