Abstract
Telescoping automobile tail fin, comprises slide rail, wing plate, actuating device three part; Described wing plate integral installation, on slide rail, wing plate has the track be harmonious with slide rail, can slide on slide rail; Described slide rail is made up of two bars spaced parallel, single bar camber; Described actuating device is made up of DC machine, gear, tooth bar, and gear is fixed on DC machine axle head, and wheel and rack engages; Described rack and pinion engages and one end is connected with wing plate; DC motor drives is rotated, and gear driven tooth bar moves, and drives wing plate to move on slide rail, realize the angle of wing plate and the adjustment of height, thus meet automobile tail air dynamic property to greatest extent, improve fuel economy, increase trailing wheel adhesive ability simultaneously, improve dynamic property and road-holding property.
Description
Art
The utility model relates to a kind of automobile tail fin device, particularly telescoping automobile tail fin.
Background technology
At present, automobile has become the indispensable vehicle of people's daily life and work, and the Environment protection and safety of automobile is people's focus all the time.Very large aerodynamic drag and aerodynamic lift can be produced during galloping.Not only excessive fuel consumption, and the lift of the tailstock is larger than the lift of headstock, just easily causes vehicle oversteer, trailing wheel earth-grasping force to reduce and high stability variation, has a strong impact on fuel economy and the safety of running car.Fixed type empennage can not regulate with aerodynamic drag size, constrains the performance of empennage effect to a great extent.Empennage is exposed at outside all the time, and under the impact of natural environment, material is easily aging, the empennage life-span is reduced, causes potential danger.And pass through the utility model---telescoping automobile tail fin, just aerodynamic drag can be reduced by actv., improve fuel economy, reduce the lift of vehicle tail simultaneously, improve road-holding property, telescoping in turn ensure that the adjustment empennage height when running at high speed, and when stopping, empennage automatic retraction is in car boot cover.
Summary of the invention
The object of the utility model design solves above-mentioned Problems existing, a kind of telescoping automobile tail fin is provided, make automobile when friction speed travels, real-time adjustment empennage angle and height, make it more to meet air dynamic behaviour, reduce aerodynamic drag, improve trailing wheel earth-grasping force, thus reduction fuel oil consumption, improve travel safety.
The utility model solves the technical scheme that above-mentioned Problems existing adopts: telescoping automobile tail fin, comprises slide rail, wing plate, actuating device three part; Described wing plate integral installation, on slide rail, it has the track be harmonious with slide rail, can slide on slide rail; Described slide rail is made up of two bars spaced parallel, single bar camber; Described actuating device is made up of DC machine, gear, tooth bar; Described gear is fixed on DC machine axle head, and wheel and rack engages; Described rack and pinion engages and one end is connected with wing plate; DC motor drives is rotated, and gear driven tooth bar moves, and drives wing plate to move on slide rail, thus realizes the angle of wing plate and the adjustment of height.
Advantage of the present utility model:
1, structure is simple, and cost is low, energy-conserving and environment-protective.
2, according to different speed of operation adjustment empennage, thus automobile tail air dynamic property can be met to greatest extent, improve fuel economy, increase trailing wheel adhesive ability simultaneously, improve dynamic property and road-holding property;
3, telescoping empennage, low speed and static time empennage automatic retraction, ensure that the overall aesthetics of vehicle, and play a part positive to the life-span extending empennage.
Accompanying drawing explanation
Fig. 1 is telescoping automobile tail fin device schematic diagram.
1. wing plate, 2. slide rail, 3. DC motor, 4. tooth bar, 5. gear
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Telescoping automobile tail fin described in the utility model, comprises slide rail (2), wing plate (1), actuating device three part; Described actuating device comprises DC motor (3), gear (5), tooth bar (4); Slide rail (2) is fixed on car boot cover inside, for wing plate (1) provides tracks and support, wing plate (1) is arranged on slide rail (2), have the track be harmonious with slide rail (2), wing plate (1) is identical with slide rail (2) radian; Tooth bar (4) one end is connected with wing plate (1), and same hour rack (4) engages with gear (5), and gear (5) is fixed on the axle head of DC machine (3).When automobile travels with the different speed of a motor vehicle, DC machine (3) carries out adjusting and working according to automobile tail air dynamic characteristic, shaft end gear (5) is driven to rotate, gear (5) drives the tooth bar (4) engaged with it to move, tooth bar (4) drives connected wing plate (1) in the upper motion of slide rail (2), thus adjustment wing plate (1) is exposed at angle and the height of automobile tail, realize the corresponding different empennage angle of the different speed of a motor vehicle and height, final realization meets tail air dynamic property to greatest extent, improves fuel economy and travel safety.
