[0002] This application claims priority and benefit to Korean Patent Application No. 10-2024-0193520, filed on December 23, 2024, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] This utility model relates to a rear spoiler device for vehicles. Background Technology

[0004] As a vehicle travels, its body tends to rise with increasing speed, which reduces tire traction, decreasing driving stability and potentially causing accidents. To prevent this, a spoiler is installed on the vehicle. Because spoilers alter airflow, they are also called air deflectors. These spoilers are accessories configured to use airflow to push the vehicle body downwards as it travels.

[0005] This type of air spoiler is installed at the rear of the vehicle, which has limitations in design freedom, makes it difficult to change the design after installation, and can lead to a decrease in design quality when applied to high-end vehicles.

[0006] Therefore, there are limitations to the technology of using spoilers to improve aerodynamic performance in order to improve vehicle fuel efficiency and driving stability, and it is necessary to change the shape of the vehicle or the specifications of the spoiler to improve additional aerodynamic performance.

[0041] Figures 1 to 9 The invention illustrates a spoiler device according to an embodiment of the present invention, as well as the construction and operation mode of the spoiler device.

[0042] Referring to the accompanying drawings, a rear spoiler device for a vehicle according to an embodiment of the present invention may include an actuator 1000, a housing 2000, a spoiler 3000, and a drive module 4000.

[0043] Actuator 1000 can be connected to a vehicle control unit (not shown) and can generate power according to signals transmitted from the control unit. In an embodiment, an electric motor can be used as actuator 1000. Actuator 1000 can be connected to shaft 1100 to rotate shaft 1100. Shaft 1100 can rotate clockwise or counterclockwise to drive spoiler 3000.

[0044] The housing 2000 has a guide groove 2100, and the actuator 1000 can be coupled to and secured to the housing 2000. The housing 2000 as a whole may have a plate-like structure extending along the width direction of the vehicle. In an embodiment, the housing 2000 may be installed inside the trunk lid T of the vehicle C.

[0045] The guide groove 2100 may include a central guide groove 2110 located in the central portion of the housing 2000 and side guide grooves 2120 located on both sides of the housing 2000. The central guide groove 2110 and the side guide grooves 2120 may extend along the width direction of the housing, that is, along the longitudinal direction of the vehicle.

[0046] A pair of guide rails 2200 may be disposed in the housing 2000. Each guide rail 2200 may be disposed adjacent to the side guide groove 2120. The guide rails 2200 may have a travel space 2210 extending in the longitudinal direction of the vehicle.

[0047] The shaft 1100 may be provided with a structure extending along the longitudinal direction of the housing 2000 (i.e., the width direction of the vehicle), and the two ends of the shaft 1100 may be located in the moving space 2210.

[0048] In one embodiment, the guide rail 2200 can be attached to the housing 2000 via fastening components (such as bolts). Of course, the guide rail 2200 can also be integrally formed with the housing 2000.

[0049] The spoiler 3000 can be mounted on the housing 2000 and slide in the front-to-back direction. The spoiler 3000 may include a frame portion 3100 and a flap portion 3200.

[0050] like Figure 2 As shown, the spoiler 3000 is configured to operate in a first mode M1 and a second mode M2. In the first mode M1, the frame portion 3100 and the flap portion 3200, which are located in the basic mode M0 where the spoiler 3000 is disposed inside the trunk lid T, move linearly from the end of the trunk lid T and are removed along the forward direction of the vehicle. In the second mode M2, the flap portion 3200, which is located in the first mode M1, is tilted and deployed.

[0051] For example, the spoiler 3000 can operate in a first mode M1 during slow driving. In the first mode M1, the spoiler 3000 implements a variable structure that extends the end of the trunk lid T rearward, thereby reducing vortices at the rear of the vehicle C and increasing driving range. Furthermore, in inclement weather and during high-speed driving, the spoiler 3000 can operate after switching from the first mode M1 to the second mode M2. Therefore, driving stability can be improved.

[0052] The frame portion 3100 is connected to the retainer 4300 of the drive module 4000, which will be described below, so as to slide together with the retainer 4300. That is, as the retainer 4300 moves, the frame portion 3100 connected to the retainer 4300 also moves.

[0053] The frame portion 3100 may have a guide rod 3110 connected to the guide groove 2100. The guide rod 3110 may include a central guide rod 3111 connected to the central guide groove 2110 and a side guide rod 3112 connected to the side guide groove 2120. When the frame portion 3100 slides in connection with the guide groove 2100, the guide rod 3110 may guide the frame portion 3100 in the front-back direction.

[0054] The flap portion 3200 can be disposed on the frame portion 3100 and rotatably connected to the frame portion 3100.

[0055] The flap bracket 3210 can be attached to the bottom surface of the flap portion 3200, and the frame bracket 3120 can be attached to the frame portion 3100. The flap portion 3200 can be connected to the frame portion 3100 via a linkage module 3300 that connects the flap bracket 3210 to the frame bracket 3120. Furthermore, when the linkage module 3300 rotates, the flap portion 3200 is configured to rotate upward and tilt relative to the frame portion 3100.

[0056] like Figures 4 to 6 As shown, the linkage module 3300 may include a drive linkage 3310, a first connecting linkage 3320, a second connecting linkage 3330, a first driven linkage 3340, and a second driven linkage 3350.

[0057] One end of the drive link 3310 can be rotatably connected to the drive module 4000, which will be described below. The drive link 3310 can be moved in the back-and-forth direction and rotate the first connecting link 3320 using power transmitted from the drive module 4000.

[0058] One end of one surface of the first connecting link 3320 can be rotatably connected to the front of one side of the frame bracket 3120, and the other end of the same surface can be rotatably connected to the other end of the drive link 3310.

[0059] One end of the first driven link 3340 can be rotatably connected to the front of the other side of the frame bracket 3120, and the other end can be rotatably connected to the front of one side of the flap bracket 3210.

[0060] One end of the second driven link 3350 can be rotatably connected to the rear of the other side of the frame bracket 3120, and the other end can be rotatably connected to the rear of one side of the flap bracket 3210.

[0061] One end of the second connecting link 3330 can be rotatably connected to the other surface of the first connecting link 3320, and the other end can be rotatably connected to the other end of the second driven link 3350. In this case, the other end of the second driven link 3350 can be connected to the flap support 3210 through the second connecting link 3330.

[0062] When the drive link 3310 moves in the rearward direction of the vehicle via the operation of the drive module 4000, the other end of the first connecting link 3320 moves upward and rotates backward from the frame bracket 3120, using the end connected to the frame bracket 3120 as the axis of rotation. When the first connecting link 3320 rotates backward, the second connecting link 3330 also moves backward, and the second driven link 3350 connected to the second connecting link 3330 rotates backward using the end connected to the frame bracket 3120 as the axis of rotation, and moves upward from the frame bracket 3120, while simultaneously moving the flap bracket 3210 backward. Furthermore, the backward and forward movement of the front portion of the flap bracket 3210 is limited by the first driven link 3340. In other words, when the first driven link 3340 and the second driven link 3350, which are respectively connected to the front and rear of the flap support 3210, rotate rearward, the flap support 3210 moves rearward, and the rear of the flap support 3210 can be lifted by the second driven link 3350 and the second connecting link 3330. The second driven link 3350 and the second connecting link 3330 have a relatively longer length than the first driven link 3340, and can therefore be set to tilt at an angle of approximately 40°. Therefore, the flap portion 3200 can enter the second mode M2 ​​state.

[0063] When the flap bracket 3210 is tilted, and the drive module 4000 moves the drive link 3310 forward, the first connecting link 3320, the first driven link 3340, and the second driven link 3350 can rotate forward in opposite directions, and the flap bracket 3210 can return to its original position and can be set to be parallel to the frame bracket 3120. Therefore, the flap section 3200 can switch from the second mode M2 ​​to the first mode M1.

[0064] In this way, the flap portion 3200 can be tilted upward relative to the frame portion 3100 to switch to the deployed state by rotating the linkage module 3300, and rotated downward in the deployed state to make close contact with the frame portion 3100 to switch to the closed state.

[0065] In one embodiment, the spoiler 3000 may be equipped with a taillight 3400.

[0066] The rear light 3400 may include a lamp housing 3410 attached to the end of the frame portion 3100, and a plurality of light sources (not shown) may be disposed in the lamp housing 3410. In an embodiment, a light-emitting diode (LED) may be used as the light source.

[0067] The lamp housing 3410 can extend in the longitudinal direction of the frame portion 3100. Multiple light sources can be arranged along the lamp housing 3410.

[0068] The taillight 3400 can be attached to the rear of the spoiler 3000 and exposed rearward from the vehicle at the end of the trunk lid T. The taillight 3400 can be used as a daytime driving light and brake light.

[0069] In particular, since the taillights 3400 can still operate normally even when the frame portion 3100 is moved to the rear of the vehicle in the first mode M1 and the second mode M2, the visibility of the driver behind or following the vehicle can be improved and accidents can be prevented.

[0070] The operation of the spoiler 3000 in the first mode M1 and the second mode M2 ​​can be performed by driving the drive module 4000. The drive module 4000 is configured to transmit power from the actuator 1000 to the spoiler 3000. The drive module 4000 can be configured as a pair of drive modules.

[0071] As shown in the figure, the drive module 4000 may include a first loader 4100, a second loader 4200, a retainer 4300, and an ejector 4400.

[0072] One end of the first loader 4100 can be connected to the end of the shaft 1100 on the moving space 2210. When the shaft 1100 rotates, the first loader 4100 can be configured to rotate together with the shaft 1100. That is, when the shaft 1100 rotates in one direction, the first loader 4100 uses the shaft 1100 as an axis to rotate in the same direction as the shaft 1100.

[0073] One end of the second loader 4200 can be rotatably connected to the other end of the first loader 4100. The second loader 4200 can be configured to move its other end along the movement space 2210 in the longitudinal direction when the first loader 4100 rotates. That is, the second loader 4200, together with the first loader 4100, can convert the rotational motion of the shaft 1100 into linear motion of the vehicle in the longitudinal direction.

[0074] A pair of connecting protrusions 4210 may be provided at the other end of the second loader 4200. One of the connecting protrusions 4210 may be connected to one end of the drive link 3310. In addition, the other of the connecting protrusions 4210 may be connected to the ejector 4400.

[0075] The retainer 4300 can be configured to slide along the movement space 2210 from the front end to the rear end of the guide rail 2200. Specifically, the retainer 4300 is connected to the ejector 4400, and as the ejector 4400 moves forward and backward via the second loader 4200, the retainer 4300 also moves forward and backward.

[0076] Meanwhile, the frame portion 3100 of the spoiler 3000 can be connected to the retainer 4300. The frame portion 3100 also moves forward and backward together with the retainer 4300.

[0077] The retainer 4300 may be formed with a structure having a generally rectangular shape, the structure having a width corresponding to the dimension of the moving space 2210 in the width direction, and may have an internal space 4310 extending in the longitudinal direction of the moving space 2210.

[0078] The guide cam 4320 can be rotatably coupled to the retainer 4300. In an embodiment, the retainer 4300 has an opening 4330 that is open in the width direction of the travel space 2210, and the guide cam 4320 can be rotatably coupled to the opening 4330. The opening 4330 can be configured as a pair of openings, and the guide cam 4320 can also be configured as a pair of guide cams.

[0079] The guide cam 4320 may include a connecting shaft 4321 corresponding to the rotation axis, a first surface 4322 and a second surface 4323 connected at right angles, and a curved third surface 4324 connecting the first surface 4322 to the second surface 4323. In an embodiment, the guide cam 4320 may have a quadrant shape.

[0080] The guide cam 4320 can be configured to project into the interior space 4310 by rotation. In this case, the third surface 4324 can be configured to face the interior space 4310, and the second surface 4323 can be configured to be parallel to the outer surface of the retainer 4300.

[0081] The guide cam 4320 can be configured to project outward from the internal space 4310 by rotation. In this case, the third surface 4324 can be configured to face the outer surface of the retainer 4300, and the first surface 4322 can be configured to be parallel to the inner surface of the retainer 4300.

[0082] The guide rail 2200 may have a receiving groove 2220 for receiving a guide cam 4320 protruding outward from the internal space 4310. The receiving groove 2220 may be configured to be recessed from the inner surface of the guide rail 2200 toward the outer surface of the guide rail 2200, and the dimension of the movement space 2210 in the width direction may be further increased in the receiving groove 2220.

[0083] The ejector 4400 can be disposed within the internal space 4310 of the retainer 4300 and configured to move forward and backward along the internal space 4310. The ejector 4400 may include a body 4410 and a connecting rod 4420. The body 4410 and the connecting rod 4420 may be integrally formed.

[0084] The body 4410 may have a substantially rectangular structure with a width corresponding to the dimension of the internal space 4310 in the width direction, and may move from the front end to the rear end of the internal space 4310. The body 4410 may have an insertion slot 4411 into which a guide cam 4320 protruding into the internal space 4310 is inserted. The insertion slot 4411 may be formed such that the outer surface of the body 4410 facing the inner surface of the retainer 4300 is recessed inward.

[0085] The connecting rod 4420 can be configured to extend rearward from the rear end of the body 4410 relative to the vehicle. One end of the connecting rod 4420 can be rotatably connected to one of a pair of connecting protrusions 4210 disposed at the other end of the second loader 4200. Therefore, when the second loader 4200 moves rearward, the ejector 4400 moves forward and rearward along the internal space 4310 of the retainer 4300. This connection structure of the second loader 4200 and the ejector 4400 operates to allow the second loader 4200 to move linearly forward and rearward. That is, the second loader 4200 is configured to move linearly forward and rearward by connecting the connecting protrusion 4210 disposed at the other end to the ejector 4400.

[0086] As the ejector 4400 moves forward and backward, the retainer 4300, which is connected to the ejector 4400 via the guide cam 4320, also moves forward and backward.

[0087] Reference Figure 8 and Figure 9 In the basic mode M0 state, with the spoiler 3000 housed inside the trunk lid T, the first loader 4100 can be positioned facing the front of the vehicle, and the second loader 4200 can be stacked on top of the first loader 4100. A retainer 4300 can be located at the front end of the movement space 2210, and an ejector 4400 can be located at the front end of the interior space 4310. A guide cam 4320 can be positioned to protrude into the interior space 4310 and insert into the insertion recess 4411 of the ejector 4400 for connection to the ejector 4400.

[0088] When the operation of actuator 1000 activates the first mode M1, the first loader 4100 rotates toward the rear of the vehicle, and the second loader 4200 moves linearly rearward. The first loader 4100 and the second loader 4200 can be deployed in a triangular shape.

[0089] When the second loader 4200 moves backward, the ejector 4400 connected to the connecting protrusion 4210 of the second loader 4200 and the retainer 4300 connected to the ejector 4400 via the guide cam 4320 can also move backward. Specifically, in the operating section of the first mode M1, the guide cam 4320 contacts the inner surface of the guide rail 2200 and remains protruding into the internal space 4310, and when the guide cam 4320 is inserted into the insertion slot 4411, the ejector 4400 and the retainer 4300 move backward together along the movement space 2210 of the guide rail 2200. At this time, with the ejector 4400 located at the front end of the internal space 4310, the retainer 4300 can be located at the rear end of the movement space 2210.

[0090] As the retainer 4300 moves rearward along the movement space 2210, the frame portion 3100 of the spoiler 3000 connected to the retainer 4300 also moves linearly from the end of the trunk lid T toward the rear of the vehicle together with the flap portion 3200 and is removed (see...). Figure 2 ).

[0091] When the additional operation of actuator 1000 activates the second mode M2, the first loader 4100 rotates further to the rear of the vehicle, and the second loader 4200 moves further rearward. The first loader 4100 and the second loader 4200 can be deployed in a substantially straight shape.

[0092] As the second loader 4200 moves further rearward, the ejector 4400 can move further rearward and guide the linear movement of the second loader 4200. Specifically, in the operating section of the second mode M2, the retainer 4300 remains stationary and is located at the rear end of the movement space 2210, and only the ejector 4400 moves along the inner space 4310 towards the rear end of the inner space 4310. Additionally, the guide cam 4320 protrudes outward from the inner space 4310 by rotation and is received in the receiving groove 2220 of the guide rail 2200. Furthermore, when the guide cam 4320 is separated from the insertion groove 4411, the ejector 4400 moves rearward along the inner space 4310.

[0093] Since the retainer 4300 does not move, the frame portion 3100 of the spoiler 3000 remains in a state where it has moved outward from the end of the trunk lid T toward the rear of the vehicle. Furthermore, as the second loader 4200 moves linearly rearward, the flap portion 3200 rotates and tilts upward relative to the frame portion 3100 through the rotational operation of the linkage module 3300, which includes a drive linkage 3310 connected to the connecting protrusion 4210 of the second loader 4200.

[0094] Simultaneously, when the actuator 1000 operates to partially rotate and move the first loader 4100 and the second loader 4200 forward, the flap portion 3200 can rotate downward relative to the frame portion 3100 in the deployed state and can come into close contact with the frame portion 3100, thus switching to the first mode M1. Furthermore, when the actuator 1000 is further operated to fully rotate and move the first loader 4100 and the second loader 4200 forward, the flap portion 3200 and the frame portion 3100 insert into the trunk lid T and switch to the basic mode M0.

[0095] In this way, according to an embodiment of the present invention, the spoiler 3000 can be driven in dual motions, such as a first mode M1 and a second mode M2. In the first mode M1, the spoiler 3000 moves linearly toward the rear of the vehicle C and unfolds. In the second mode M2, the flap portion 3200 of the spoiler 3000 is tilted and opened into an unfolded state, thereby maximizing the aerodynamic effect.

[0096] Furthermore, the rear light 3400 in the frame portion 3100 of the spoiler 3000 can be configured as a rear lighting device, and can also be used as a rear lighting device in the first mode M1 of deploying the spoiler 3000 and the second mode M2 ​​of opening the flap portion 3200, thereby improving stability and marketability.

[0097] According to an embodiment of the present invention, a rear spoiler device for a vehicle can be provided, the rear spoiler device being installed inside the trunk lid of the vehicle to be moved to the rear of the vehicle and tilted to regulate airflow, thereby improving driving stability and aerodynamic performance.
