Description

Active Air Flap Device for Vehicle The present invention relates to an active air flap device for a vehicle, and more specifically, to an active air flap device for a vehicle that opens and closes the opening of a radiator grille of a vehicle. Generally, a radiator grille is installed at the front of the vehicle to allow air to be introduced into the engine compartment of the vehicle, and the air introduced through the radiator grille is used to cool various coolers such as radiators. However, when a vehicle travels at high speed, the airflow entering the engine compartment through the radiator grille acts as resistance to the vehicle's movement. To address this, active air flaps that open and close the radiator grille are being applied recently. Conventional active air flaps operated simply to open and close the radiator grille, which resulted in a problem where structural stability was compromised as the flap would be pushed when aerodynamic or external forces were applied to it. In particular, as the flap operates to close the radiator grille when the vehicle is traveling at high speed, significant aerodynamic and external forces act on the flap during closure; therefore, a structure is required to prevent the flap from sliding in this situation.
