[0002] The air intake grille is an important part of the car's exterior design. It is usually located at the front of the car. Its main function is to guide air to the engine and cooling system. Through the air intake grille, the car can effectively dissipate heat and keep the engine within the normal operating temperature range. In addition to functionality, the air intake grille also plays an aesthetic role in the car's exterior design. Different design styles and shapes can enhance the car's sporty feel and brand characteristics. In recent years, with the rise of electric and hybrid vehicles, the air intake grilles of some models have even adopted a closed design to reduce wind resistance and improve energy efficiency.

[0003] However, the air intake grilles on the market often cannot adjust their air intake angles, resulting in a significant reduction in their air intake function and functional effects. For this reason, we have proposed an air intake grille with good mechanical properties. Utility Model Content
