Description

Technical Field

[0001] The present disclosure relates to a double spoiler device that controls airflow to the rear of a vehicle to improve aerodynamic performance. Background Art

[0002] When the vehicle is traveling at high speed or turning, the grip of the rear tires is reduced, which is not conducive to increasing the driving speed and reduces driving stability.

[0003] In order to solve this problem, an air spoiler is installed at the rear of the vehicle to change the air flow passing around the vehicle and generate pressure according to the air flow around the air spoiler to press the vehicle, thereby improving the grip of the rear tires.

[0004] This air spoiler is installed at the rear of the vehicle, which limits the freedom of design. It is difficult to change the design once the air spoiler is installed, and when applied to high-end vehicles, the design is hindered by the installation of the air spoiler.

[0005] As mentioned above, air spoilers are only a technology for improving aerodynamic performance to improve vehicle fuel efficiency and driving stability. In order to further improve aerodynamic performance, the shape of the vehicle must be changed or the specifications of the air spoilers must be changed.

[0006] Furthermore, in the case of an SUV vehicle, there is a constraint on the installation space for the air deflector, so that the specification of modifying the air deflector is limited. For example, since a space is required to install a component for opening and closing the tailgate at the rear of the vehicle, there is a constraint on the space when installing a component dedicated to providing a specific function to the air spoiler.

[0007] The above content (described as background technology) is only intended to help understanding the background of the present disclosure, but is not intended to mean that the present disclosure falls within the scope of the relevant technology known to ordinary technicians in the field. Summary of the invention

[0008] The present disclosure has been made to solve the above-mentioned problems in the prior art. One aspect of the present disclosure provides a double spoiler device configured to change the tilt angle and length of an air spoiler to control the airflow to the rear of a vehicle, thereby improving aerodynamic performance. The present disclosure also simplifies the components for changing the tilt angle and length, resulting in a reduction in the required installation space and a solution to the quality problem.

[0009] According to an embodiment of the present disclosure, a dual spoiler device may include: a first spoiler device configured to slide on a spoiler mounting portion in a front-to-rear direction of a vehicle; and a second spoiler device configured to tilt on the spoiler mounting portion in an up-and-down direction of the vehicle. The dual spoiler device also includes: a driving device to which the first spoiler device and the second spoiler device are connected. In particular, the driving device may generate a driving force to change a sliding position of the first spoiler device and an inclined position of the second spoiler device.

[0010] The spoiler mounting portion may correspond to a rear upper portion of the vehicle, and the spoiler mounting portion may be configured to cause the first spoiler to slide toward the rear of the vehicle when the first spoiler is extended, and wherein the spoiler mounting portion is configured to cause the angle of the second spoiler to increase and thereby tilt when the second spoiler is deployed.

[0011] The first spoiler device may include: a first rotating shaft configured to rotate by receiving a driving force of a driving device; and a first spoiler connected to the first rotating shaft and configured to slide when the first rotating shaft rotates. The second spoiler device may include: a second rotating shaft configured to rotate by receiving a driving force of the driving device; and a second spoiler connected to the second rotating shaft and configured to tilt when the second rotating shaft rotates.

[0012] The first spoiler device can also include a guide rail and a moving member. Specifically, the guide rail can be installed in the spoiler mounting portion and can extend in the front-rear direction. The moving member can be movably arranged on the guide rail, and the first spoiler is installed to the moving member. The first rotating shaft is connected to the moving member. Utilize this configuration, when the moving member is transmitted with driving force, the moving member can move on the guide rail, thereby changing the position of the first spoiler.

[0013] The second spoiler device may further include a connecting rod mechanism, and the connecting rod mechanism may be installed in the spoiler mounting portion. The second spoiler is mounted to the connecting rod mechanism, and the connecting rod mechanism may be configured as a plurality of connecting rods, and the second rotation axis is connected to the connecting rods. Thus, when each connecting rod is transmitted with a driving force, each connecting rod rotates to change the total length of the connecting rods, thereby changing the tilt position of the second spoiler.

[0014] The driving device may include a first driving unit and a second driving unit. The first rotating shaft may be connected to the first driving unit, and the second rotating shaft may be connected to the second driving unit.

[0015] The driving device may include a driving motor and a connecting unit, and the connecting unit may include an electromagnet and a connecting member. The connecting unit may be configured to selectively connect to the first rotating shaft or the second rotating shaft according to a moving position of the connecting member to transmit the driving force of the driving motor.

[0016] The drive motor may include a drive shaft, a first driving gear and a second driving gear. The first driving gear and the second driving gear are configured to rotate freely on the drive shaft. Specifically, the first rotating shaft may have a first driven gear meshed with the first driving gear, and the second rotating shaft may have a second driven gear meshed with the second driving gear.

[0017] The connecting member may be disposed between the first driving gear and the second driving gear, and when the connecting member is moved in the axial direction by the electromagnet member, the connecting member may be connected to the first driving gear or the second driving gear.

[0018] The connecting member may include a connecting arm connected to the electromagnet member and extending between the first driving gear and the second driving gear. The connecting member may also include a connecting gear member formed in the connecting arm and configured to face the first driving gear and the second driving gear respectively, the connecting gear member meshing with the first driving gear or the second driving gear, and the driving shaft passes through the connecting gear member and is connected to the connecting gear member.

[0019] A fastening gear part may be formed in the first driving gear and the second driving gear, respectively, and a connecting gear part may be arranged at the outer periphery of the fastening gear part to match the fastening gear part. Teeth may be formed on the inner surface of the connecting gear part, and the connecting gear part may be configured to rotate freely on the connecting arm.

[0020] The connecting member may include a first stop member and a second stop member arranged therein, and according to the moving position of the connecting member, the first stop member contacts the first driven gear or the second stop member contacts the second driven gear, so that the first stop member contacts the first driven gear and the second stop member is separated from the second driven gear, or the first stop member is separated from the first driven gear and the second stop member contacts the second driven gear.

[0021] The first driven gear may have first through holes distributed along its circumference, and the second driven gear may have second through holes distributed along its circumference. In particular, the first stopper is configured to be insertable into the first through hole, and the second stopper is configured to be insertable into the second through hole.

[0022] When the sliding position of the first spoiler device is to be changed, the connecting member can be connected to the first driving gear so that the first stopper is separated from the first driven gear and the second stopper is in contact with the second driven gear. When the tilting position of the second spoiler device is to be changed, the connecting member can be connected to the second driving gear so that the first stopper is in contact with the first driven gear and the second stopper is separated from the second driven gear.

[0023] In another embodiment, the dual spoiler device may further include a controller configured to control the driving device. The controller may control the position of the first spoiler device and the position of the second spoiler device according to the driving speed of the vehicle.

[0024] When the travel speed of the vehicle increases, the controller may control the drive device so that the first spoiler device or the second spoiler device is deployed in stages in proportion to the amount of acceleration of the vehicle.

[0025] In the case where it is determined that the travel speed of the vehicle is reduced, the controller may control the driving device to retract the first spoiler device and deploy the second spoiler device to have a maximum tilt angle.

[0026] Since the double spoiler device in the above structure is configured to change the inclination angle and length of the air spoiler, the aerodynamic performance can be improved by controlling the airflow flowing to the rear of the vehicle and the components for changing the inclination angle and length can be simplified, thereby reducing the installation space and solving the quality problem.

[0049] Hereinafter, a double spoiler apparatus according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 2 As shown, the double spoiler device according to the present disclosure includes: a first spoiler device 100, which slides on a spoiler mounting portion 100a in the front-rear direction of the vehicle; and a second spoiler device 200, which is tilted on the spoiler mounting portion 100a in the up-down direction of the vehicle. The double spoiler device also includes a driving device 300, which is connected to the first spoiler device 100 and the second spoiler device 200 and generates a driving force to change the sliding position of the first spoiler device 100 and the tilting position of the second spoiler device 200.

[0051] The first spoiler device 100 is extended or retracted while sliding in the front-rear direction on the spoiler mounting portion 100a, and the second spoiler device 200 is deployed or stored while changing the tilt angle on the spoiler mounting portion 100a.

[0052] Here, the spoiler mounting portion 100a may correspond to a rear upper portion of the vehicle, and the first spoiler device 100 and the second spoiler device 200 may be provided by utilizing a space where a tailgate is installed.

[0053] The airflow to the rear of the vehicle can be controlled by the first spoiler device 100 and the second spoiler device 200 , and since the vortex generated in the rear of the vehicle is separated from the vehicle, the drag force can be reduced so that the aerodynamic performance can be improved.

[0054] The first spoiler device 100 may be configured to slide out 150 mm from the rear of the vehicle to be extended, and the second spoiler device 200 may be implemented to have a tilt angle of up to 90 degrees.

[0055] The first spoiler device 100 and the second spoiler device 200 are connected to the driving device 300, and are position-changed by the driving force transmitted from the driving device 300. The driving device 300 can selectively generate the driving force under the control of the controller 400, and the forward rotation or reverse rotation of the driving device 300 can perform the extension or retraction of the first spoiler 120 and the deployment or storage of the second spoiler 220.

[0056] In one embodiment, the first spoiler device 100 may include: a first rotating shaft 110, which rotates by receiving a driving force of the driving device 300; and a first spoiler 120, which is connected to the first rotating shaft 110 and slides when the first rotating shaft 110 rotates. In another embodiment, the second spoiler device 200 may include: a second rotating shaft 210, which rotates by receiving a driving force of the driving device 300; and a second spoiler 220, which is connected to the second rotating shaft 210 and tilts when the second rotating shaft 210 rotates.

[0057] like Figure 3 and Figure 4 As shown, the first spoiler device 100 is configured as a first rotating shaft 110 and a first spoiler 120 such that the first rotating shaft 110 is connected to the driving device 300 and rotates by receiving the driving force of the driving device, and the first spoiler 120 slides according to the rotation of the first rotating shaft 110.

[0058] like Figure 5 and Figure 6 As shown, the second spoiler device 200 is configured as a second rotating shaft 210 and a second spoiler 220, so that the second rotating shaft 210 is connected to the driving device 300 and rotates by receiving the driving force of the driving device, and the second spoiler 220 tilts according to the rotation of the second rotating shaft 210.

[0059] Specifically, Figure 3 and Figure 4 As shown, a guide rail 130 and a moving member 140 may also be provided in the first spoiler device 100 .

[0060] The guide rail 130 is mounted on the spoiler mounting portion 100a and extends in the front-rear direction. A pair of guide rails 130 may be provided in the spoiler mounting portion 100a and may be configured to extend a distance over which the first spoiler 120 is deployed.

[0061] The moving member 140 is movably arranged on the guide rail 130, and the first spoiler 120 is mounted to the moving member, and the first rotating shaft 110 is connected to the moving member. A groove may be formed along the longitudinal direction of the guide rail 130, and the moving member 140 may have a protrusion formed to be inserted into the groove, so that the movement of the moving member 140 can be guided along the guide rail 130.

[0062] The first rotating shaft 110 may have a pinion gear, and the moving member 140 may be a rack gear, so that when the first rotating shaft 110 rotates, the moving member 140 may move linearly according to the rotational force of the first rotating shaft.

[0063] Therefore, the first spoiler 120 may move together with the moving member 140 to extend from or retract into the spoiler mounting portion 100 a .

[0064] At the same time, if Figure 5 and Figure 6 As shown, the second spoiler device 200 may further include a linkage mechanism 230 .

[0065] The link mechanism 230 is installed in the spoiler mounting portion 100 a and includes a plurality of links. The second spoiler 220 is installed to the link mechanism 230 .

[0066] Here, when the second rotating shaft 210 is connected to any one of the plurality of links, the rotational position of each link changes according to the rotation of the second rotating shaft 210, thereby changing the vertical lengths of the plurality of links by folding or unfolding operations of the plurality of links caused by the rotation of the plurality of links.

[0067] The linkage 230 may be configured as a three-link linkage, and the second spoiler 220 may be installed in the uppermost linkage so that the angle of the second spoiler 220 increases as the linkage 230 is deployed. The angle change of the second spoiler 220 may be configured according to the length of each linkage.

[0068] As described above, the first and second spoiler devices 100 and 200 may slide or tilt according to rotation of the first and second rotating shafts 110 and 210 , respectively, and the first and second rotating shafts 110 and 210 are connected to the driving device 300 and receive a rotational force therefrom.

[0069] like Figure 7As shown, the driving device 300 can be configured as a plurality of units, namely, a first driving unit 310 and a second driving unit 320. In one embodiment, the driving device 300 includes: a first driving unit 310 and a second driving unit 320, and the first rotating shaft 110 is connected to the first driving unit 310, and the second rotating shaft 210 is connected to the second driving unit 320, so that the spoiler device connected to the corresponding rotating shaft can change its own position according to whether the corresponding driving unit is running. The first driving unit 310 and the second driving unit 320 can be configured as motors capable of forward rotation and reverse rotation.

[0070] In another embodiment, the driving device 300 includes a driving motor 330 and a connecting unit 340, the connecting unit 340 includes an electromagnet member 350 and a connecting member 360, and the connecting unit is configured to selectively connect to the first rotating shaft 110 or the second rotating shaft 210 according to the moving position of the connecting member 360 to transmit the driving force of the driving motor 330, so that either the first spoiler device 100 or the second spoiler device 200 changes its position.

[0071] like Figure 8 and Fig. 9 As shown, the driving device 300 may include a driving motor 330 and a connecting unit 340. In one form, a single driving motor 330 can achieve position change of the first spoiler device 100 and position change of the second spoiler device 200.

[0072] The driving motor 330 may be configured as a motor capable of forward and reverse rotation.

[0073] The connection unit 340 may include an electromagnet member 350 and a connection member 360 , and the connection member 360 may be connected to the electromagnet member 350 , so that a position of the connection member 360 may be changed depending on whether the electromagnet member 350 is powered.

[0074] Here, the electromagnet member 350 includes a plurality of electromagnets 352 and a connecting shaft 353 spaced apart from each other in a housing 351, such that a stopper 354 is coupled to the connecting shaft 353, and an elastic member 355 supports the stopper 354 between the electromagnets 352. Therefore, if power is supplied to the electromagnet 352, the stopper 354 moves, and the connecting shaft 353 moves accordingly. When the connecting member 360 is connected to the connecting shaft 353, the position of the connecting member 360 can be changed together with the connecting shaft 353.

[0075] In other words, the position of the connecting member 360 can be determined according to whether the electromagnet 352 is operating, and the connecting member 360 can be selectively connected to the first rotating shaft 110 or the second rotating shaft 210 according to the moving position of the connecting member 360, so that the position of either the first spoiler device 100 or the second spoiler device 200 can be changed when the driving motor 330 is operating.

[0076] Specifically, the driving motor 330 may have a driving shaft 331 and a first driving gear 332 and a second driving gear 333 that rotate freely on the driving shaft 331 , and the first rotating shaft 110 may have a first driven gear 111 that meshes with the first driving gear 332 , and the second rotating shaft 210 may have a second driven gear 211 that meshes with the second driving gear 333 .

[0077] In other words, even when the drive motor 330 is running and the drive shaft 331 is rotating, the first driving gear 332 and the second driving gear 333 may not rotate. Therefore, even when the first driven gear 111 of the first rotating shaft 110 is meshed with the first driving gear 332 and even when the second driven gear 211 of the second rotating shaft 210 is meshed with the second driving gear 333, when the drive shaft 331 rotates, the first rotating shaft 110 and the second rotating shaft 210 may not rotate. Here, the first driven gear 111 and the first driving gear 332 may be meshed with each other in a helical gear structure. Similarly, the second driven gear 211 and the second driving gear 333 may be engaged with each other in a helical gear structure.

[0078] When the connecting member 360 of the connecting unit 340 is connected to the first rotating shaft 110 or the second rotating shaft 210, the rotational force of the driving motor 330 can be transmitted, so that the first rotating shaft 110 or the second rotating shaft 210 to which the connecting member 360 is connected rotates, thereby changing the position of any one of the first spoiler device 100 and the second spoiler device 200.

[0079] The connector 360 is described in detail, such as Fig.10 As shown, the connecting member 360 is disposed between the first driving gear 332 and the second driving gear 333 , and when the connecting member is moved in the axial direction by the electromagnet member 350 , the connecting member is connected to the first driving gear 332 or the second driving gear 333 .

[0080] The connecting member 360 is coupled to the connecting shaft 353 of the electromagnet member 350, and is configured to be located between the first driving gear 332 and the second driving gear 333 to be connected to the first driving gear 332 or the second driving gear 333 when the connecting member is moved in the axial direction by the electromagnet member 350. Therefore, the driving force is transmitted to the driving gear to which the connecting member 360 is connected among the first driving gear 332 and the second driving gear 333, and the rotating shaft connected to the driving gear through the driven gear rotates, thereby changing the position of the corresponding spoiler.

[0081] Here, the connecting member 360 may include a connecting arm 361 coupled to the electromagnet member 350 and extending between the first driving gear 332 and the second driving gear 333. The connecting member 360 may also include a plurality of connecting gear members 362, which are arranged to face the first driving gear 332 and the second driving gear 333, respectively, to mesh with the first driving gear 332 or the second driving gear 333, and to allow the connected driving shaft 331 to pass through the connecting gear member. In one embodiment, the connecting gear member 362 is formed in the connecting arm 361.

[0082] In other words, the connecting member 360 is configured as a connecting arm 361 and a connecting gear member 362 .

[0083] Here, the connection arm 361 is coupled to the electromagnet part 350 and extends between the first driving gear 332 and the second driving gear 333 , and has a through hole portion at which the connection gear part 362 is disposed.

[0084] The connecting gear member 362 is rotatably mounted to the through hole portion of the connecting arm 361. The connecting gear member 362 may be mounted in a bearing structure to freely rotate on the connecting arm 361. In addition, the connecting gear member 362 is disposed to face each other between the first driving gear 332 and the second driving gear 333, and the connecting gear member is engaged with the first driving gear 332 or the second driving gear 333 according to the moving position of the connecting arm 361.

[0085] The connecting gear member 362 can be connected to the driving shaft 331 passing therethrough, and the portion of the connecting gear member 362 passed by the driving shaft 331 and the outer surface of the driving shaft 331 can have a nonlinear shape, so that the connecting gear member 362 and the driving shaft 331 can be connected to allow their linear motion but limit their relative rotation.

[0086] In order to selectively engage the connecting gear member 362 with the corresponding driving gear, a fastening gear member G can be formed in the first driving gear 332 and the second driving gear 333 respectively, and the connecting gear member 362 can be arranged at the outer periphery of the fastening gear member G to match the fastening gear member, and teeth can be formed on the inner surface of the connecting gear member.

[0087] The fastening gear members G may be respectively provided in the first driving gear 332 and the second driving gear 333 , and may have spur teeth extending in the moving direction of the connection arm 361 .

[0088] The connection gear member 362 has teeth formed on the inner circumference thereof to match the outer circumference of the fastening gear member G and to mesh with the teeth of the fastening gear member G. In addition, the connection gear member 362 is configured to freely rotate on the connection arm 361 .

[0089] Therefore, when the connecting arm 361 moves toward the first driving gear 332 through the electromagnet part 350, the fastening gear part G of the first driving gear 332 can move into the connecting gear part 362 to engage with each other, so that the driving force of the driving motor 330 connected to the connecting gear part 362 can be transmitted to the first driving gear 332, thereby rotating the first rotating shaft 110, and thus the first spoiler 120 of the first spoiler device 100 can slide.

[0090] On the other hand, when the connecting arm 361 moves toward the second driving gear 333 through the electromagnet part 350, the fastening gear part G of the second driving gear 333 can move to the connecting gear part 362 to engage with each other, so that the driving force of the driving motor 330 connected to the connecting gear part 362 can be transmitted to the second driving gear 333, thereby rotating the second rotating shaft 210, and thus the second spoiler 220 of the second spoiler device 200 can be tilted.

[0091] At the same time, if Figures 8 to 10 As shown, the connecting member 360 includes a first stopper 363 and a second stopper 364 .

[0092] According to the movement position of the connecting member 360 , the first stopper 363 or the second stopper 364 contacts the first driven gear 111 or the second driven gear 211 , respectively.

[0093] Specifically, it may be configured such that only one of the first stopper 363 and the second stopper 364 contacts the first driven gear 111 or the second driven gear 211 .

[0094] In other words, if the first stopper 363 contacts the first driven gear 111 , the rotation of the first driven gear 111 is blocked, and the second stopper 364 is separated from the second driven gear 211 , thereby allowing the second driven gear 211 to rotate.

[0095] On the other hand, if the second stopper 364 contacts the second driven gear 211 , the rotation of the second driven gear 211 is blocked, and the first stopper 363 is separated from the first driven gear 111 , thereby allowing the first driven gear 111 to rotate.

[0096] As described above, in the present disclosure, one of the first rotation shaft 110 and the second rotation shaft 210 is selectively rotated by the first stopper 363 and the second stopper 364 of the connecting member 360. In addition, when one spoiler of the first spoiler device 100 and the second spoiler device 200 changes its position, the other spoiler can maintain a fixed state at the corresponding position.

[0097] Specifically, Figure 8 As shown, the first through holes H1 may be formed in the first driven gear in a form distributed along the circumference of the first driven gear 111, and the second through holes H2 may be formed in the second driven gear in a form distributed along the circumference of the second driven gear 211. The first stopper 363 may be configured to be insertable into the first through hole H1, and the second stopper 364 may be configured to be insertable into the second through hole H2.

[0098] In the present disclosure, the first stopper 363 and the second stopper 364 can be formed in the form of pins, so that the first stopper 363 can be inserted into the first through hole H1 formed in the first driven gear 111, and the second stopper 364 can be inserted into the second through hole H2 formed in the second driven gear 211.

[0099] Here, since a plurality of first through holes H1 are formed in the first driven gear along the circumference of the first driven gear 111, the first stopper 363 can be inserted into the first driven gear at various rotational positions of the first driven gear 111. Similarly, since a plurality of second through holes H2 are formed in the second driven gear along the circumference of the second driven gear 211, the second stopper 364 can be inserted into the second driven gear at various rotational positions of the second driven gear 211.

[0100] In addition, in the present disclosure, since the connecting arm 361 is located between the first driving gear 332 and the second driving gear 333, the first stopper 363 and the second stopper 364 can be formed to extend from the connecting arm 361 to the outside of the first driven gear 111 or the outside of the second driven gear 211, respectively, and then bend to be inserted into the corresponding through holes.

[0101] Thus, the present disclosure can perform position conversion of the first spoiler device 100 and the second spoiler device 200 .

[0102] That is to say, Fig.10 As shown, if the connection arm 361 is in the initial state between the first driving gear 332 and the second driving gear 333 by the electromagnet member 350 , the position change of the first spoiler device 100 and the second spoiler device 200 is not performed.

[0103] At this time, the driving motor 330 is not driven, the first stopper 363 contacts the first driven gear 111, and the second stopper 364 contacts the second driven gear 211, so that the positions of the first spoiler device 100 and the second spoiler device 200 are fixed.

[0104] Here, if Fig.11 As shown, when the sliding position of the first spoiler device 100 is to be changed, the connecting member 360 is connected to the first driving gear 332 so that the first stopper 363 is separated from the first driven gear 111 and the second stopper 364 is in contact with the second driven gear 211 .

[0105] That is, if the connection arm 361 is moved toward the first driving gear 332 by the electromagnet part 350 , the connection gear part 362 of the connection arm 361 is engaged with the fastening gear part G of the first driving gear 332 .

[0106] In addition, when the first stopper 363 of the connection member 360 is separated from the first driven gear 111 , the first rotation shaft 110 is allowed to rotate, and when the second stopper 364 is in contact with the second driven gear 211 , the second rotation shaft 210 is not allowed to rotate.

[0107] Here, when the driving motor 330 is driven, the sliding position of the first spoiler 120 may be changed by the rotation of the connecting gear member 362 , the first driving gear 332 , the first driven gear 111 , and the first rotating shaft 110 .

[0108] At the same time, if Fig.12 As shown, when the tilt position of the second spoiler device 200 is to be changed, the connecting member 360 is connected to the second driving gear 333 so that the first stopper 363 contacts the first driven gear 111 and the second stopper 364 is separated from the second driven gear 211 .

[0109] If the connection arm 361 is moved toward the second driving gear 333 by the electromagnet part 350 , the connection gear part 362 of the connection arm 361 is meshed with the fastening gear part G of the second driving gear 333 .

[0110] In addition, when the second stopper 364 of the connection member 360 is separated from the second driven gear 211 , the second rotation shaft 210 is allowed to rotate, and when the first stopper 363 is in contact with the first driven gear 111 , the first rotation shaft 110 is not allowed to rotate.

[0111] Here, when the driving motor 330 is driven, the tilt position of the second spoiler 220 may be changed by the rotation of the connecting gear member 362 , the second driving gear 333 , the second driven gear 211 , and the second rotating shaft 210 .

[0112] Meanwhile, a controller 400 for controlling the driving device 300 may be further included. The controller 400 may control the positions of the first spoiler device 100 and the second spoiler device 200 according to the driving speed.

[0113] Specifically, if the travel speed of the vehicle increases, the controller 400 may control the driving device 300 so that the first spoiler device 100 or the second spoiler device 200 is staged and deployed in proportion to the amount of acceleration of the vehicle.

[0114] In other words, the extension amount of the first spoiler device 100 and the deployment amount of the second spoiler device 200 can be adjusted in stages according to the driving speed of the vehicle, thereby controlling the airflow. At this time, the control of the first spoiler device 100 and the second spoiler device 200 according to the driving speed can be performed in this way, that is, the control of the extension amount of the first spoiler device 100 precedes the control of the deployment amount of the second spoiler device 200.

[0115] Meanwhile, if it is determined that the travel speed of the vehicle is rapidly reduced, the controller 400 may control the driving device 300 so that the first spoiler device 100 is retracted and the second spoiler device 200 is deployed to have a maximum tilt angle.

[0116] For example, if the vehicle decelerates by 60 km / h or more within 2 seconds, which corresponds to rapid deceleration, the second spoiler device 200 is deployed to the maximum tilt angle, thereby implementing air braking. Therefore, the braking distance of the vehicle can be reduced.

[0117] Since the double spoiler device in the above structure is configured to change the inclination angle and length of the air spoiler, the aerodynamic performance can be improved by controlling the airflow flowing to the rear of the vehicle and the components for changing the inclination angle and length can be simplified, thereby reducing the installation space and solving the quality problem.

[0118] While the present disclosure has been described and illustrated in conjunction with specific embodiments thereof, it should be apparent to those skilled in the art that various improvements and modifications may be made to the present disclosure without departing from the technical concept of the present disclosure as defined by the appended claims.
