Patent ID: 8302715

Claim:
An apparatus for opening and closing an air flap for a vehicle, comprising: a coolant temperature sensor provided at a predetermined position of an engine to measure a coolant temperature of the engine; a control unit comparing a measurement value input from the coolant temperature sensor with a reference value stored therein, thus outputting a control signal; an actuator rotating forwards or backwards in response to the control signal of the control unit; a power transmission unit connected to the actuator to transmit rotating force of the actuator; and a flap unit installed in an opening of a front end module carrier which extends from a radiator grill to a cooling module, and being selectively movable in a vertical direction in the opening by power transmitted from the power transmission unit to the flap unit to open or close the opening, thus permitting or preventing an inflow of air into the cooling module, wherein the flap unit comprises: guide columns provided in the opening to extend in a vertical direction thereof, and spaced apart from each other at regular intervals in a widthwise direction of the opening; an upper flap provided on a side of each of the guide columns, fitted into the opening in such a way as to move vertically, and occupying about half of an area of the opening; and a lower flap provided on an opposite side of each of the guide columns, fitted into the opening in such a way as to move vertically, and occupying a remaining about half of the area of the opening.
