What's the name of the plastic plate under the front bumper?
The plastic plate under the front bumper is called the deflector plate, which is usually secured with screws or fasteners and can be removed by itself. The main function of the deflector is to reduce the resistance generated by the car during high-speed driving.
The deflector is a downward inclined connection plate installed under the bumper of the front end of the car. The connection plate is integrated with the front skirt of the body to reduce the air pressure under the car in this way.
In addition to some improvements in the body design of the car, in this way to reduce the wind resistance generated by the car during the driving process. The baffle can not only reduce the fuel consumption of the car, but also improve the safety of driving.
In addition to the deflector, the equipment to reduce the wind resistance of the car is the car spoiler, the car spoiler refers to the part installed on the rear box cover of the car, that is, the car's tail wing.
The role of the deflector
01 Stable
The deflector plays a key stabilizing role in automobile design. Its main purpose is to reduce the lift generated by the car when driving at high speed, so as to avoid the adhesion between the wheel and the ground is reduced, resulting in unstable car driving. When the car reaches a certain speed, the lift may exceed the weight of the car, causing the car to float. To counter this lift, the deflector is designed to create a downward pressure under the car, thereby increasing the adhesion of the wheels to the ground and improving the car's driving stability. In addition, the tail (which is also a type of deflector) creates downforce at high speeds, further reducing lift but potentially increasing the drag coefficient.
02 Dredge air flow
The main function of the deflector is to divert the air flow. In the process of spraying, by adjusting the Angle of the deflector, the wind direction can be controlled, so that the drug can be accurately sprayed to the designated area. In addition, the baffle can also reduce the speed of the dust-containing air flow and distribute it evenly under the action of the secondary diversion, so as to ensure the effective purification of the gas.
03 Disrupt and reduce air flow into the underside of the car
The main function of the deflector is to disturb and reduce the air flow into the bottom of the car, thus reducing the lift force generated by the air flow on the car when driving at high speed. When the car is traveling at high speeds, the instability of the bottom air flow causes an increase in lift, which can affect the stability and handling of the car. The design of the deflector can effectively disrupt and reduce this unstable air flow, thereby reducing the lift and improving the driving stability of the car.
04 Reduced air resistance
The main function of the deflector is to reduce air resistance. On vehicles, aircraft, or other objects moving at high speeds, air resistance consumes a lot of energy, which affects performance. The design of the deflector can effectively change the direction and speed of the air flow, so that it flows more smoothly through the object, thereby reducing air resistance. This not only improves energy efficiency, but also improves the overall performance of the object.
05 Purify air flow from under the chassis
The deflector serves to purify the air flow from under the chassis in vehicle design. The main purpose of this design is to reduce air pollution such as dust, mud and other impurities under the chassis, thus ensuring that the vehicle does not inhale these pollutants while driving. By effectively diverting and filtering these air currents, the deflector helps to improve the driving performance and ride comfort of the vehicle, while also helping to extend the service life of the vehicle.
