The function of the blade is:
1: Use fluid mechanics to reduce the drag coefficient and make the car run more smoothly.
2. When the car is running, prevent the silt rolled up by the wheels from splashing to the bottom of the car.
The function of automobile bumper:
1: safety: the car can play a buffering role in the event of a low-speed collision, protect the front and rear car bodies, and play a certain role in protecting pedestrians in the event of an accident with pedestrians.
2. Appearance: decorative, which has become an important part of decorating the appearance of the car, and the bumper of the car also has a certain aerodynamic effect. The outer plate and cushioning material of the bumper are plastic, and the cross beam is punched into a U-shaped groove with a thickness of about1.5 mm. The outer plate and cushioning material are attached to the cross beam, and the cross beam is connected with the longitudinal beam of the frame by screws and can be disassembled.
Bumpers at the front and rear ends of automobiles are not only decorative, but more importantly, they are safety devices that absorb and mitigate external shocks, protect the car body and protect the safety of passengers. Bumper has the functions of safety protection, vehicle decoration and improving aerodynamic characteristics of vehicles. From the safety point of view, cars can play a buffering role in the event of a low-speed collision accident.
Protect the front and rear car bodies; In the event of an accident with pedestrians, it can play a certain role in protecting pedestrians. From the appearance, it is decorative and becomes an important part of decorating the appearance of cars; At the same time, the automobile bumper also has a certain aerodynamic effect.
Installing door bumpers means placing several high-strength steel beams horizontally or obliquely in the door panel of each door to play the role of bumpers at the front and rear of the car, so that the whole car has bumpers to "protect the car" and form a "iron wall", so that the occupants in the car have a maximum safety area.
Of course, installing this kind of door bumper will undoubtedly increase some costs for automobile manufacturers, but for the occupants in the car, the safety guarantee will increase a lot.
