Description

Air flap device {AIR FLAP APPARATUS}

The present invention relates to an air flap device, and more specifically, to an air flap device that allows or does not allow air from the front of the vehicle toward the engine room to pass through.

Generally, an air flap device is a housing disposed between a grille and a radiator of a vehicle or formed integrally with the grille and having a vent for passing air from the front of the vehicle toward the engine room, and rotating the housing to open and close the vent. It includes a flap that can be installed and an actuator that rotates the flap, and when the vehicle is driven at high speed, the ventilation hole is closed with the flap to prevent air from passing from the front of the vehicle to the engine room, thereby reducing air resistance of the vehicle. , It is a device that lowers the temperature of the engine room and cools various parts by opening the ventilation hole with the flap when the temperature of the engine room rises and allowing air from the front of the vehicle to pass through the engine room.

However, such a conventional air flap device had a problem in that it had a large weight as it was formed to have a rigidity exceeding a predetermined level to prevent damage by external forces such as driving wind.

Hereinafter, the operational effects of the air flap device according to this embodiment will be described.

That is, for example, when the vehicle is traveling at high speed, the drive shaft 320 may be rotated in one direction by the motor 310. Accordingly, the first flap 210 to the fourth flap 240 are connected to the first shaft portion 214 to the fourth flap by the eccentric portion 322 of the drive shaft 320 and the link lever 330, respectively. 4 The ventilation hole 160 can be closed by rotating in one direction based on the shaft portion 244. As a result, air heading toward the engine room from the front of the vehicle cannot pass through the vent 160, thereby reducing air resistance of the vehicle.

On the other hand, for example, when the temperature of the engine room rises, the drive shaft 320 may be rotated in the opposite direction by the motor 310. Accordingly, the first flap 210 to the fourth flap 240 are connected to the first shaft portion 214 to the fourth flap by the eccentric portion 322 of the drive shaft 320 and the link lever 330, respectively. 4 The ventilation hole 160 can be opened by rotating in the opposite direction based on the shaft portion 244. Accordingly, as air heading toward the engine room from the front of the vehicle passes through the vent 160, the temperature of the engine room is lowered and various parts can be cooled.

At this time, the motor 310 may be actively controlled based on parameters such as the vehicle's coolant temperature.

Here, the air flap device according to this embodiment includes front grooves (126a, 146a, 156a) and rear grooves (116b, 126b, 146b) that are engraved on the surface of the housing 100, so that the weight is savings can be achieved.

In addition, as the front grooves 126a, 146a, and 156a are formed small, deterioration of air resistance due to the front grooves 126a, 146a, and 156a can be suppressed.

In addition, by further including ribs 118ba, 128ba, and 128bb protruding from the inner surfaces of the rear grooves 116b and 126b, a decrease in the rigidity of the housing 100 due to the rear grooves 116b and 126b is suppressed. You can.

In addition, as the ribs 118ba, 128ba, and 128bb are formed in plurality, and at least some of the plurality of ribs 118ba, 128ba, and 128bb (128ba and 128bb) are formed to cross each other, the rigidity of the housing 100 This may increase further.

In addition, as the cross-sectional areas of the ribs 118ba, 128ba, and 128bb are formed to be smaller than the cross-sectional areas of the rear grooves 116b and 126b, the rigidity of the housing 100 is improved without significantly reducing the weight of the housing 100. This can be reinforced.

And, as the housing 100 includes guard parts 124, 144, and 154 that cover the bearing spaces (S2, S4, S51, and S52), in particular, the bearing spaces (S2, S4, S51, and S52) As it includes front guard parts (124a, 144a, 154a, 154c) that cover the front, as well as side guard parts (124b, 144b, 154b, 154d) that cover the sides of the bearing space (S2, S4, S51, S52), When the ventilation hole 160 is closed, air and foreign matter can be prevented from flowing into the engine room through the axle storage spaces (S2, S4, S51, and S52).

In addition, the flap 200 has a flange portion (212ae, 212af, 212be, 212bf, As it includes 222ae, 222af, 222be, 222bf, 232ae, 232af, 232be, 232bf, 242ae, 242af, 242be, 242bf), when the ventilation hole 160 is closed, air and foreign substances are stored in the axle space (S2, S4, The inflow into the engine room through S51, S52) can be further suppressed.

In addition, as the side guard portions 124b, 144b, 154b, and 154d include interference portions 124bb, 144bb, 154bb, and 154db that can contact the flap 200, the flap 200 is connected to the vent 160. ) can be prevented from rotating further than a predetermined position.

And, as sound-absorbing members 412, 414, 422, 424, 432, 434, 442, 444, 452, and 454 are disposed between the flap 200 and a counterpart that can contact the flap 200, the flap When 200 closes the vent 160, collision noise between the flap 200 and the counterpart can be reduced.

Here, in the case of the present embodiment, as the flaps 200 are formed in four pieces, that is, as the first flap 210 to the fourth flap 240 are provided, an opponent who can contact the first flap 210 The water is the first frame edges 119a and 119b and the second flap 220, and the opponents that can contact the second flap 220 are the first flap 210 and the third flap 230. , the opponents that can be contacted with the third flap 230 are the second flap 220 and the fourth flap 240, and the opponents that can be contacted with the fourth flap 240 are the third flap 230. ) and the third frame edges 139a and 139b, or the number of flaps 200 can be adjusted appropriately, and the counterpart that can contact the flap 200 can also be changed accordingly. That is, for example, the entire vent 160 may be configured to open and close with the first flap 210, and in this case, the counterpart that can contact the first flap 210 is the first frame edge 119a. , 119b) and the third frame edges 139a and 139b. Alternatively, the entire vent 160 may be configured to open and close with the first flap 210 and the second flap 220, and in this case, the counterpart that can contact the first flap 210 is the first flap 210. The frame edges 119a and 119b and the second flap 220, and the opponents that can contact the second flap 220 may be the first flap 210 and the third frame edges 139a and 139b. there is.

Meanwhile, in the case of this embodiment, in order to improve the balance of the flap 200, reduce driving force, and reduce operating deviation, only one of a pair of sound-absorbing members provided on both sides of one flap is fixed to the one flap. That is, for example, the 1-1 sound-absorbing member 412 is provided at the first rotation end 212ac of the 1-1 plate section, and the second rotation end 212ad of the 1-1 plate section is provided with the first sound-absorbing member 412. A 2-1 sound-absorbing member 422 is provided, and only the 2-1 sound-absorbing member 422 is fixed to the 1-1 plate portion 212a, and the 1-1 sound-absorbing member 412 is connected to the first sound-absorbing member 412. It is fixed to the frame first edge 119a. However, the present invention is not limited to this, and the pair of sound-absorbing members may be respectively fixed to both sides of the single flap. That is, for example, not only the 2-1 sound-absorbing member 422 but also the 1-1 sound-absorbing member 412 may be fixed to the 1-1 plate portion 212a. However, in this case, it may be desirable for the pair of sound-absorbing members to be formed identically to each other so that the balance of the single flap is maintained.

Here, in the case of this embodiment, the first frame as well as the sound-absorbing members 422, 424, 432, 434, 442, 444, 452, and 454 fixed to the first flap 210 to the fourth flap 240 The sound-absorbing members 412 and 414 fixed to 110 are formed identically to each other, but the sound-absorbing members 412 and 414 fixed to the first frame 110 are the first flap 210 to the fourth flap. It does not necessarily need to be formed identically to the sound-absorbing members 422, 424, 432, 434, 442, 444, 452, and 454 fixed to (240).
