The invention provides an active air-inlet grille and a vehicle, and relates to the field of vehicle parts, the active air-inlet grille comprises a frame body, blades, a connecting rod mechanism, a fixing support and an actuator, a driving shaft of the actuator and a first connecting rod are fixed at a first connecting point, and one end of a second connecting rod is rotatably connected with the first connecting rod around a second connecting point; the two ends of the third connecting rod are rotationally connected with the fixing support and the fifth connecting rod respectively, the two ends of the fourth connecting rod are rotationally connected with the fixing support and the fifth connecting rod respectively, and the fifth connecting rod is fixedly connected with the blades. When the blade closes the air inlet, the first connecting point, the second connecting point and the third connecting point are all located on a first straight line, and the first straight line is tangent to a circle with the fourth connecting point as the circle center and the distance between the fourth connecting point and the third connecting point as the radius. Self-locking of the blades in the closed state can be achieved, and an actuator is not prone to being damaged.
本发明提供了一种主动进气格栅及车辆,涉及车辆零部件领域,包括框体、叶片、连杆机构、固定支架及执行器,执行器的驱动轴与第一连杆固定于第一连接点,第二连杆的一端与第一连杆绕第二连接点转动连接,另一端与第三连杆的中部绕第三连接点转动连接,第三连杆的两端分别与固定支架及第五连杆转动连接,第四连杆的两端分别与固定支架及第五连杆转动连接,第五连杆与叶片固定连接;令第三连杆与固定支架的连接点为第四连接点,在叶片将进气口关闭时,第一连接点、第二连接点以及第三连接点均位于第一直线,且第一直线与以第四连接点为圆心,以第四连接点及第三连接点之间的距离为半径的圆相切。能够实现叶片在关闭状态下的自锁,且不易损坏执行器。
