[0002] In the field of modern automobile design, with the continuous improvement of vehicle fuel economy and aerodynamic performance requirements, active grille (AGS) technology has become an important means to improve vehicle performance. Traditional fixed grilles cannot automatically adjust the air intake according to the vehicle's driving status and external environment, resulting in insufficient engine heat dissipation or excessive wind resistance under certain working conditions, affecting the overall performance of the vehicle.

[0003] In order to overcome this defect, active grille technology came into being. By driving the opening and closing or adjusting the angle of the blades by a motor, precise control of the intake volume can be achieved. However, the existing active grille blade mechanism still faces many challenges in design and manufacturing, especially the blade mechanism of the external active grille. On the one hand, the external active grille has more stringent requirements on the appearance and needs to reduce the shrinkage problem on the blade surface; on the other hand, it is necessary to meet the overall structural strength of the blade and achieve the required functions, while having strong manufacturability.

[0004] Based on this, the applicant proposed a snap-on double-blade mechanism for an active air intake grille to solve the above technical problems. Utility Model Content
