[0057] The accommodating portion 16 may have an opening on its outer surface facing the rear of the vehicle. The rear lamp 100 is received inside the accommodating portion 16. The rear lamp 100 is fixedly mounted in the accommodating portion, and emits light in the form of a line toward the rear of the vehicle through the edge of the rear lamp 100 located in the opening of the accommodating portion 16.
[0058] The actuator 17 is provided in the rear vehicle body 15. The actuator 17 may be connected to the accommodation portion 16 and may move the rear lamp 100 in a straight line in the front-rear direction of the vehicle.
[0059] An operation process of the variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure having the above-described configuration will be described below.
[0060] Figure 1 is a perspective view showing a general mode in a variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure.
[0061] refer to Figure 1 and Figure 8 When the driving mode of the vehicle is set to the general mode, the control unit 20 may control the operation of the first actuator 12 so that the tail lamp 100 is embedded in the rear vehicle body 11 so as not to protrude toward the rear of the vehicle.
[0062] The diffuser 300 , which moves in association with the rear lamp 100 , moves toward the front of the vehicle and does not protrude toward the rear of the vehicle like the rear lamp 100 .
[0063] The spoiler 200 moving together with the rear lamp 100 also does not protrude toward the rear of the vehicle. The control unit 20 may control the operation of the second actuator 13 so that the tilt angle of the spoiler 200 is 0 degrees.
[0064] When the driving mode of the vehicle is set to the general mode, the control unit 20 may control the first lamp 110 to be turned off, and may control the second lamp 120 to be turned on.
[0065] Figure 2 is a perspective view showing a GT1 mode in a variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure.
[0066] refer to Figure 2 and Figure 8When the driving mode of the vehicle is set to the GT1 mode, the control unit 11 may control the operation of the first actuator 12 so that the rear lamp 100 embedded in the rear vehicle body 11 is exposed from the rear vehicle body 11 and protrudes toward the rear of the vehicle.
[0067] The diffuser 300 , which moves in association with the rear lamp 100 , moves and protrudes toward the rear of the vehicle like the rear lamp 100 .
[0068] The spoiler 200 moving together with the rear lamp 100 also protrudes toward the rear of the vehicle. The control unit 20 may control the operation of the second actuator 17 so that the inclination angle of the spoiler 200 continues to be maintained at 0 degrees. The movement of the rear lamp 100 and the diffuser 300 can increase the running distance of the vehicle by flowing the vortex generated at the rear of the vehicle.
[0069] When the driving mode of the vehicle is set to the GT1 mode, the control unit 20 may control the first lamp 110 from off to on, and may control the second lamp 120 to remain on.
[0070] Figure 3 is a perspective view showing a GT2 mode in a variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure.
[0071] refer to Figure 3 and Figure 8 , when the driving mode of the vehicle is set to the GT2 mode, the control unit 20 may control the operation of the second actuator 13 so that the tilt angle of the spoiler 200 is about 40 degrees to about 45 degrees.
[0072] The control unit 20 can control the operation of the first actuator 12 so that the rear lamp 100 moving toward the rear of the vehicle remains protruding toward the rear of the vehicle. When the vehicle is traveling at a constant speed or high speed, the inclination of the spoiler 200 can minimize air resistance by making the air at the rear of the vehicle flow further than in a general mode.
[0073] When the driving mode of the vehicle is set to the GT2 mode, the control unit 20 may control the first lamp 110 from off to on when the spoiler 200 is tilted, and may control the second lamp 120 to remain on.
[0074] Figure 4 is a perspective view illustrating a rain mode in a variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure.
[0075] refer to Figure 4 and Figure 8 , when the driving mode of the vehicle is set to the rain mode, the control unit 20 may control the operation of the second actuator 13 so that the tilt angle of the spoiler 200 is about 80 degrees to about 90 degrees.
[0076] The control unit 20 may control the operation of the first actuator 12 so that the rear lamp 100 moving toward the rear of the vehicle remains protruding toward the rear of the vehicle. The inclination of the spoiler 200 may help ensure safe driving by suppressing the airflow around the vehicle to improve tire grip and straight-line stability when the vehicle is traveling at high speed or in extremely bad weather.
[0077] When the driving mode of the vehicle is set to the rain mode, the control unit 20 may control the first lamp 110 from off to on when the spoiler 200 is tilted, and may control the second lamp 120 to remain on.
[0078] The variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure can improve the driving distance of the vehicle by minimizing the air resistance occurring at the rear of the vehicle through the rear lamp 100 and the diffuser 300 protruding to the rear of the vehicle according to the driving mode, and the spoiler 200 protruding to the rear of the vehicle together with the rear lamp 100 and having a variable inclination angle in the vertical direction according to the driving mode.
[0079] The variable spoiler lighting device for a vehicle according to an embodiment of the present disclosure may provide visual information to a driver of another vehicle or a pedestrian through the rear lamp 100 that moves in the front-rear direction of the vehicle according to a driving mode.
[0080] Although the present disclosure has been described with respect to the embodiments shown in the accompanying drawings, it will be apparent to those skilled in the art that these embodiments are provided by way of example only. It will be appreciated by those skilled in the art that various modifications and other equivalent embodiments may be made without departing from the spirit and scope of the present disclosure.
