The invention discloses an active air-inlet grille. The active air-inlet grille comprises a grille frame, a plurality of driving grating blades and driven grating blades are vertically and rotationally connected between the upper row and the lower row of the air inlets in the two sides of the grating frame; the driving grating blades are controlled to rotate through a driving device, and the driving grating blades drive the driven grating blades to rotate synchronously through a transmission device. And the vehicle-mounted ECU is in data connection with the driving device for control. When an automobile runs, a vehicle-mounted ECU controls the driving device through a preset control strategy according to the working condition of the whole automobile, and under the driving of the driving device, the grid blades are driven to turn over to reach a preset angle, so that the grid blades are driven to rotate synchronously. The driven grille blades are driven by the transmission device to turn over synchronously, the air inlet amount is adjusted by adjusting the opening angle of the grille so as to meet the requirement for the real-time air inlet amount, and then the effects of optimizing wind resistance and improving the thermal load of an engine compartment are achieved.

    本发明公开了一种主动进气格栅,包括格栅框架;格栅框架的两侧进风口上排与下排之间竖直转动连接有若干个驱动格栅叶片和从动格栅叶片;驱动格栅叶片通过驱动装置进行控制转动,驱动格栅叶片通过传动装置带动从动格栅叶片进行同步转动;车载ECU数据连接驱动装置进行控制。驱动格栅叶片通过传动装置带动从动格栅叶片进行同步转动当汽车行驶时,车载ECU会通过事先设定好的控制策略根据整车工况来对驱动装置进行控制,在驱动装置的驱动下,驱动格栅叶片翻转到达预定的角度,并通过传动装置带动从动格栅叶片同步翻转,通过调节格栅打开的角度来调节进风量以满足实时进风量的需求,进而达到优化风阻和改善发动机舱热负荷的作用。
