The invention discloses a control method of a vehicle air inlet grille. The engine water temperature T is detected, the lowest set value of the water temperature of the engine is T1; the highest set value of the water temperature of the engine is T2; if T < = T1, the grille blades are driven by the double self-locking mechanisms to be overturned to the completely-closed position and kept at the completely-closed position; if T is larger than T1 and smaller than T2, the grille blades are kept at the current opening position through the double self-locking mechanism, and if T is larger than or equal to T2, the grille blades are driven by the double self-locking mechanisms to be overturned to the complete opening position and kept at the complete opening position; the double self-locking mechanism comprises a worm and gear device connected with the grating blades and a gear and rack device which is connected with the power output end of the linear reciprocating driving mechanism and can transmit power to the worm and gear device. The action of finally driving the air inlet grille blades is completed through the gear and rack device and the worm and gear device, and the switching of the opening state and the closing state of the air inlet grille blades and the double-self-locking function are achieved.

    本发明公开了一种车辆进气格栅的控制方法,检测发动机水温T,发动机水温的最低设定值为T1,发动机水温的最高设定值为T2,若T≤T1,则通过双自锁机构驱动格栅叶片翻转至完全关闭位置并保持在完全关闭位置,若T1<T<T2,则通过双自锁机构使格栅叶片保持在当下开启位置,若T≥T2,则通过双自锁机构驱动格栅叶片翻转至完全开启位置并保持在完全开启位置;双自锁机构包括与格栅叶片连接的涡轮蜗杆装置和与直线往复驱动机构的动力输出端连接、可将动力传递至涡轮蜗杆装置的齿轮齿条装置。利用齿轮齿条装置和涡轮蜗杆装置完成最终驱动进气格栅叶片的动作,实现了进气格栅叶片打开和闭合两种状态的切换和双自锁功能。
