Abstract
An active air flap device for a vehicle is configured to prevent aerodynamic loss caused by the active air flap being twisted. The active air flap device for a vehicle has a structure in which a clutch link is connected between a drive shaft connected to an actuator and a drive link configured to rotate a flap to allow the drive shaft and the clutch link to rotate together to transmit a rotational driving force for opening and closing the flap to the drive link, allowing the clutch link to rotate up to a set angle and the drive shaft to further rotate by an arbitrary angle from the set angle to thereby compensate for a rotation loss in which another end portion of the flap rotates less than one end portion of the flap.
Claims14
An active air flap device for a vehicle, the device comprising:
- a housing that defines an air passage therein;
- a flap configured to open and close the air passage;
- an actuator disposed at a first side portion of the housing;
- a drive shaft connected to the actuator;
- a clutch link coupled to a first end portion of the drive shaft and configured rotate together with the drive shaft to a set angle to thereby transmit a rotational driving force of the actuator to a first end portion of the flap, the clutch link being configured to allow the drive shaft to rotate further by an arbitrary angle from the set angle;
- and
- a transmission link coupled to a second end portion of the drive shaft and configured to rotate by the arbitrary angle to thereby transmit the rotational driving force to a second end portion of the flap based on the drive shaft rotating further by the arbitrary angle from the set angle.
