Description

Technical Field

[0002] The active air intake grille of a car belongs to the field of the cold side air intake system at the front end of the car. Its main function is to close the front air intake blades when the car is driving at high speed, so that the cold side airflow flows around the car instead of entering the engine compartment, thereby reducing wind resistance. Wind resistance is one of the important factors affecting the fuel consumption of the car, thereby indirectly reducing the fuel economy and carbon dioxide emissions of the car.

[0003] The existing patent (publication number: CN216331883U) discloses an active air intake grille for an automobile, comprising a grille body, a plurality of blades being arranged on the front side of the grille body, positioning plates being fixedly connected to the middle portion of the upper end and both sides of the grille body, and a transmission mechanism being arranged between the positioning plates on both sides; a driving assembly for outputting power to the transmission mechanism is arranged at the middle portion of the upper end of the grille body, and a dust removal assembly for blowing air to the blades is arranged on the surface of the transmission mechanism.

[0004] However, the above-mentioned prior art still has certain shortcomings in actual use. It mainly blows the dust on the surface of the blade by blowing air, and some dust with strong adhesion may not be effectively blown away by blowing air. When the car is driving at high speed, the dust may still enter the interior of the car. The dust cleaning efficiency is low and the effect is not good. In view of this, we propose an active air intake grille that reduces wind resistance to solve the above problems. Utility Model Content
