, Description:TECHNICAL FIELD
[001] The present invention generally relates to a spoiler for a vehicle and more particularly, to a multi-purpose spoiler for the vehicle, which can be used for reduction of air drag (aerodynamic drag) and for cabin ventilation.
BACKGROUND
[002] Presently, many vehicles have spoilers located on the vehicle body or on tailgate to increase the vertical downward load on the vehicle thereby increasing the traction in driving condition or also to improve the aerodynamic drag coefficient by providing a clear and stable separation at tail end of the vehicle. While vehicle is in driving condition, air-flow around vehicle produces relative motion with vehicle, which causes friction force. This friction force opposes vehicle forward motion which is generally called as aerodynamic drag. Aerodynamic drag and aerodynamic lift has a very large impact on vehicle operation performance. Aerodynamic drag can directly affect velocity and fuel economy of vehicle. Aerodynamic lift not only can reduce the stability of vehicle, also can produce induced drag, directly affecting the driving safety of vehicle.
[003] For reducing aerodynamic lift, spoiler can be installed to the rear of the vehicle roof and vehicle body, in order to increase the stability of vehicle, strengthen the drivability of vehicle, traveling comfort and driving safety.
[004] Conventional vehicle cabin ventilation system includes enclosures fixed over the vehicle roof. If the vehicle is parked under sun, the cabin temperature is increased. So, the enclosures are opened to drain out the hot air from the vehicle cabin. However, these enclosures are not provided with any sealing means. Hence, there is a possibility of water/dust entry into the vehicle if vehicle is parked under sun.
[005] Another conventional vehicle cabin ventilation system include air duct(s) fixed over the roof for evacuating the hot air from the vehicle cabin when the vehicle is parked under sun or hot environment. However, these cabin ventilation systems are complex in design and require high cost for implementation.
[006] Hence, there is need of a spoiler which can be used for reducing the air drag (aerodynamic drag) and also for cabin ventilation, which alleviates drawbacks of conventional systems.

However, it is also within the scope of the invention to use the components of the spoiler (100) and modify the structural design of the spoiler body (101) for mounting the spoiler at any other location of a sports vehicle, off road vehicles or any other type of vehicles, without otherwise deterring the intended function of the spoiler (100) as can be deduced from the description and ease of understanding.
[037] The spoiler body (101) is adapted to support the first movable member (102), the second movable member (104), the blower (106), the first actuator (108) and the second actuator (110). The spoiler body (101) includes a first portion (101A), a second portion (101B) and a third portion (101C), (as shown in fig. 1 and fig. 2).

The spoiler body (101) includes at least one first air vent (101AX), (as shown in fig. 2) defined on the first portion (101A) of spoiler body (101) and it is adjacent to the first movable member (102). The spoiler body (101) includes at least one second air vent (101BX), (as shown in fig. 3) defined on the second portion (101B) of the spoiler body (101) and is adjacent to the second movable member (104). The spoiler body (101) includes at least one air outlet (101CX), (as shown in fig. 1 to fig. 4) defined on the third portion (101C) of the spoiler body (101).
[038] The first movable member (102) is adapted to facilitate reduction of vehicle air drag (aerodynamic drag). In another embodiment of the present invention shown in fig. 2, the first movable member (102) is adapted to be moved between one of an open position (as shown in fig. 6) and a closed position (as shown in fig. 5). In the open position, the blower (106) is on and the blower (106) draws ambient air (flowing over the roof) through the first air vent (101 AX) and it directs the drawn ambient air towards the air outlet (101CX) which facilitates exit of air to ambient thereby reducing vehicle air drag (aerodynamic drag). In closed position, the first movable member (102) is adapted to restrict air flow into the spoiler body (101). The first movable member (102) is positioned on the first portion (101A) of the spoiler body (101) at inner side.

Further, the method (200) includes operating, by the controller unit (C), the spoiler (100) in an active cabin ventilation mode (AV) in which the controller unit activates the second actuator (110) and the blower (106) when the cabin temperature reaches 51-70 degrees being sensed and communicated by the cabin temperature sensor (T) to the controller unit (C) or based on inputs from a user interface unit. Further, the method (200) includes, operating, by the controller unit (C), the spoiler (100) in an active aerodynamics mode (A) in which the controller unit (C) activates the first actuator (108)and the blower (106) when the vehicle speed reaches 60 KMPH being sensed and communicated by the vehicle speed sensor (S) to the controller unit (C).
Technical Advantages –
[053] The technical advantages of the spoiler (100) are as follows. The spoiler is used to reduce air drag and for cabin ventilation. The spoiler restricts water or dust entry into the vehicle cabin when the vehicle is parked for longer time or moving at higher speed. As it reduces air drag, it also improves vehicle performance. The spoiler is also working as multimode, so it is doing multiple tasks as one system. There is no need of separate cabin ventilation system thereby reducing cost. The spoiler is simple design and easy to install to the vehicle. The spoiler reduces pollutants emissions from the vehicle by improving the fuel economy of the vehicle. The spoiler enhances the comfort level of occupants in the vehicle by ventilating the cabin.
