Abstract
Disclosed herein is an active air flap for vehicles, which includes a frame unit having a hollow structure in which horizontal and vertical frames thereof are connected to each other, and configured to fluidly communicate with an outside air inlet of a grill, a flap unit having a plurality of flap members rotatably connected to the frame unit and configured to open and close the outside air inlet, a drive unit configured to provide a driving force to the flap unit, and a link unit connected between the flap unit and the drive unit to transmit the driving force from the drive unit to the flap unit.
Claims15
An active air flap for vehicles, comprising:
- a frame unit having a hollow structure in which horizontal and vertical frames thereof are connected to each other, and configured to fluidly communicate with an outside air inlet of a grill;
- a flap unit having a plurality of flap members rotatably connected to the frame unit and configured to open and close the outside air inlet;
- a drive unit configured to provide a driving force to the flap unit;
- and
- a link unit connected between the flap unit and the drive unit to transmit the driving force from the drive unit to the flap unit, wherein the vertical frame comprises:
- a first guide groove having a straight section and a curved section extending as a single path and configured to guide an opening/closing path of each of the flap members;
- and
- a second guide groove having a step spaced apart from the first guide groove and configured to guide a straight path of each of the flap members.
An active air flap for vehicles, comprising:
- a flap unit having a plurality of flap members configured to sequentially open and close an outside air inlet of a grill, located in the front of a vehicle, according to a preset logic;
- a drive unit configured to provide a driving force to the flap unit and control an open area of each of the flap members;
- and
- a link unit configured to transmit the driving force from the drive unit to the flap unit,
- wherein the drive unit comprises:
- an actuator having a drive shaft;
- a driving pinion gear rotating in conjunction with the drive shaft;
- and
- a rack reciprocating vertically along with the rotation of the driving pinion gear.
An active air flap for vehicles, comprising:
- a frame unit having a hollow structure in which horizontal and vertical frames thereof are connected to each other, and configured to fluidly communicate with an outside air inlet of a grill located in the front of a vehicle;
- a flap unit having a plurality of flap members configured to sequentially open and close the outside air inlet by sliding in a forward-rearward direction and rotating at a certain point on the vertical frame of the frame unit;
- a drive unit configured to provide a driving force to the flap unit;
- a link unit configured to transmit the driving force from the drive unit to the flap unit;
- and
- a fixing unit disposed on a sliding path of each of the flap members to prevent each of the flap members from being pushed rearward or twisted due to aerodynamics when a fixing protrusion protruding from each end of each of the flap members is seated thereon.
