Abstract
An active air flap system for a vehicle is provided. The system includes an exterior surface having at least one or more openings, a housing provided on a rear side of the exterior surface, a flap rotatably mounted on the housing, and a driving section rotating the flap to open and close the openings. The driving section has a dual link structure including a first link moving in a vertical direction and a second link connecting the first link and a flap linkage forming an operating shaft of the flap, so that when the flap is operated, the rotation angle of the flap is increased, and interference between the flap and the bumper is prevented from occurring.
Claims17
An active air flap system for a vehicle, the active air flap system comprising:
- an exterior surface disposed on a vehicle front side and having at least one opening through which external air is supplied into a vehicle interior;
- a housing provided on a rear side of the exterior surface in a front-rear direction of the vehicle;
- a plurality of flaps rotatably mounted on the housing and configured to open and close the at least one opening;
- and
- a driving section configured to rotate the plurality of flaps to open and close the at least one opening,
- wherein the driving section includes:
- a first link configured to linearly reciprocate within the housing and having a plurality of first guide holes corresponding to the plurality of flaps, respectively;
- a plurality of second links having first ends guided by the respective first guide holes of the first link and second ends;
- and
- a plurality of flap linkages having first ends and second ends, wherein the first ends of the plurality of flap linkages are rotatably connected to the second ends of the plurality of second links, respectively, and the second ends of the plurality of flap linkages are connected to the plurality of flaps, respectively,
- wherein a guide pin is formed to protrude from the first end of the second link so as to be inserted into the first guide hole, and the housing is further provided with a second guide hole, through which the guide pin is inserted through the first guide hole, to guide a reciprocating linear motion of the guide pin.
An active air flap system for a vehicle, the active air flap system comprising:
- an exterior surface disposed on a vehicle front side and having at least one opening through which external air is supplied into a vehicle interior;
- a housing provided on a rear side of the exterior surface in a front-rear direction of the vehicle;
- a plurality of flaps rotatably mounted on the housing and configured to open and close the at least one opening;

- wherein the driving section includes:
- a first link configured to linearly reciprocate within the housing and having a plurality of first guide holes corresponding to the plurality of flaps, respectively;
- a plurality of second links having first ends guided by the respective first guide holes of the first link and second ends;
- and
- a plurality of flap linkages having first ends and second ends, wherein the first ends of the plurality of flap linkages are rotatably connected to the second ends of the plurality of second links, respectively, and the second ends of the plurality of flap linkages are connected to the plurality of flaps, respectively,
- an actuator;
- and
- a loader connecting the first link and the actuator,
- wherein the loader includes a first loader portion having a first end connected to an output end of the actuator so as to rotate integrally with the actuator, and a second loader portion having a first end and a second end, and
- wherein the first end is rotatably connected to a second end of the first loader portion, and the second end is rotatably connected to the first link.
