The front bumper is a device that absorbs the external impact force and generates a cushion when the vehicle or the driver is under the impact force, and protects the person and the car.
In addition to maintaining the original protection function, the front and rear bumpers of the vehicle also pursue harmony and unity with the car body shape, and pursue its own lightweight. At present, the front and rear bumpers of the car are made of plastic, which is called a plastic front bumper. The plastic front bumper is composed of three parts: outer plate, cushioning material and beam. The plastic front bumper has strength, rigidity and decoration. From the safety point of view, the vehicle can play a buffering role in the event of a collision, and protect the front and rear body. From the appearance, it can be naturally combined with the car body. Integral, it has a very good decoration and becomes an important part of the decorative vehicle exterior.
The front 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 front bumper of the car 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, the front bumper of the door 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 front bumper to the audience to show its good safety performance.
Installing the front bumper of the door is to erect or tilt several high-strength steel beams in the door panel of each door to function as the front bumper of the front and rear of the car, so that the front bumper of the whole car has front and rear bumpers. “Guarding the car” forms a “bronze wall” that gives the car occupants a maximum safe area. Of course, the installation of this front 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.
