[0002] At present, the air intake grille is a body accessory installed at the front of the car. When the engine needs a large amount of air when working, the air intake grille opens to ensure that enough air enters the engine compartment to meet the normal operation needs of the engine. When the car needs to travel at high speed, the air intake grille is closed to reduce the car's air resistance and improve the car's aerodynamic effect.

[0003] The general air intake grille is provided with a plurality of horizontal crossbars in the vertical direction, and blades are arranged on the crossbars. When the air intake grille needs to be closed, the crossbars are rotated so that the blades are perpendicular to the horizontal plane, so that the blades completely block the flow opening of the air intake grille. When the air intake grille needs to be opened, the crossbars are rotated so that the blades are parallel to the horizontal plane, so that the flow opening is opened, so that the air intake grille can be closed and opened at the appropriate time. When assembling the air intake grille, it is necessary to select and test each blade and adjust the position of each crossbar several times so that the blades completely block the flow opening when the air intake grille is closed.
