An active air flap device for automatically locking a flap of a vehicle includes a four-bar mechanism connecting a drive shaft rotated by an actuator and a rotary shaft separated from the drive shaft and around which the flap rotates. When the four-link mechanism closes the flaps, a force of a vehicle traveling wind that rotates the flaps and a force of an actuator that locks the flaps are set to be applied in different directions. Therefore, automatic locking is realized in a force balance state. Accordingly, although the traveling wind of the vehicle applies the wind pressure to the flaps, the flaps can be prevented from being opened. Through the function of automatically locking the flaps, an actuator that produces the same output as an actuator in the prior art is used without a separate structure (e.g., a stopper).

    本公开提供一种用于车辆的风门片自动锁定的主动式空气风门片装置,包括四连杆机构,四连杆机构连接由致动器旋转的驱动轴和与驱动轴分离并且风门片绕其旋转的旋转轴。当四连杆机构关闭风门片时,使风门片旋转的车辆行驶风的力和使风门片锁定的致动器的力被设置为沿不同的方向施加。由此,在力平衡状态下实现了自动锁定。相应地,尽管车辆的行驶风将风压施加到风门片,但能够防止风门片打开。通过自动锁定风门片的功能,使用产生与现有技术中的致动器相同的输出的致动器,而无需单独的结构(例如,止动器)。
