Do you understand the role of Bumper Stop?




The front and rear bumpers of the car not only have decorative functions, but more importantly, they are safety devices that absorb and alleviate external impacts, protect the body and protect the body and the occupants. The Bumper Stop 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 body; it can play a certain role in protecting pedestrians in the event of an accident 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 Stop also has a certain aerodynamic effect.

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 serves as the front and rear Bumper Stop of the car, so that the entire car has bumpers on the front, rear, left, and right to protect the car. , 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.

Many years ago, the front and rear bumpers of automobiles were mainly made of metal materials. The U-shaped channel steel was punched out of steel plates with a thickness of more than 3 mm, and the surface was chrome-plated. It was riveted or welded with the frame rails, and compared with the body. The large gap seems to be an additional part that looks very unsightly. With the development of the automobile industry and the large-scale application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, have also moved on the road of innovation. At present, in addition to maintaining the original protection function of the front and rear bumpers of the automobile, it is also necessary to pursue harmony and unity with the shape of the car body, and to pursue its own lightweight. The front and rear bumpers of a car are made of plastic, and they are called plastic bumpers.
