Description
Technical field
The present invention relates to automobile tail guiding device, more particularly, to a kind of automobile tail light air deflector.
Background technology
With the fast development of auto industry, automobile (referring mainly to passenger car) has become very universal during we live
Product, while the attention with various countries to energy problem, the energy-conserving and environment-protective problem of automobile product also enjoys national governments and each vapour
The attention of car manufacturer, the whole world including domestic major automobile main frame maker are all proposed various pure electronic or mixed dynamic one after another
Automobile, is solved or alleviating energy crisis except by the improvement to dynamical system, substituting.Actual in major automobile vendors
In automobile research the fuel consumption of vehicle can be reduced (for electronic by reducing the air drag for middle vehicle of running at high speed
For car, the electric energy that hundred kilometers of electric car is consumed can be reduced).
Related data is shown：For a Cd*A=0.8m2Car, when speed reaches 65 kilometers per hour,
The energy of its dynamical system output have 55% be for overcoming air drag, and when speed reaches 90 kilometers per hour, this
Ratio has reached 70%.
Automobile is when running at high speed, and the air-flow of high speed passes through headstock, to hair lid, wing, then to front windshield, roof,
The car door of both sides, body bottom, most backward tail of the body region are collected, due to the functional topology requirement of automobile tail so that
Flow through that vehicle body reaches afterbody flows the afterbody in automobile with the stronger vortex of rear region one energy of formation, in automobile back shape
Into negative pressure, larger pressure differential before and after exactly this vehicle body, as vehicle resistance chief component (also have viscous drag,
Relative pressure resistance is smaller).Existing automobile tail flow-guiding structure is arranged on the back of automobile, such as Chinese Patent Application No. mostly
200710091865.3 disclose a kind of for automobile, the guiding device particularly for car, and it is arranged on automobile tail simultaneously
Include leading stream unit, the leading stream unit can be moved to the run location of stretching from the resting position of retraction.According to this
Invention, the leading stream unit automobile longitudinal direction formed at least two major flow part sections in the case of quilt
Separate so that when leading stream unit is moved to run location from resting position, at least major flow part section of side can be with
It is transverse to the longitudinal direction movement of automobile.Majority all improves the air resistance coefficient of automobile using the board-like structure of the flow-disturbing.
The content of the invention
It is an object of the invention to provide a kind of automobile tail light air deflector easy for installation, simple in construction, to increase afterbody
Vortex and the distance of vehicle body, and then increase the pressure at automobile back, so as to reduce the air drag of automobile.
The technical solution adopted for the present invention to solve the technical problems is：A kind of automobile tail light air deflector, the air deflector
Generally wedge structure, including mounting surface and guide face, the air deflector is arranged on the taillight at automobile side rear, and air deflector is thin
One end close to vehicle front end, thick one end is close to vehicle afterbody.
Further, the guide face and both sides be provided with the chamfering of arc transition.
For effectively reduction coefficient of air resistance, the setting height(from bottom) of the air deflector is at the position of center line of taillight.It is described
Air deflector is installed and away from taillight sideways and at 1~3mm of rear transition flex point distance position.
Beneficial effects of the present invention：By setting the air deflector of wedge shape on automobile tail light, opened originally along taillight surface
The begin air-flow of separation is guided to the region away from vehicle body, the region of trailing vortex formation from a distance from vehicle body than not installing taillight additional
The trailing vortex formed during air deflector (the now pressure increase at automobile back remote from a distance from vehicle body.Due to installing taillight water conservancy diversion additional
After device, the pressure increase of rear portion bodywork surface, and the anterior pressure of vehicle there is no change, cause the pressure differential before and after vehicle
Value is decreased, so the resistance of vehicle is smaller than not installing taillight air deflector additional.Tail can be effectively increased by the structure
The distance of bilge vortex and vehicle body, and then increase the pressure at automobile back, so as to reduce the air drag of automobile.And it is simple in construction,
It is easy for installation.
Below with reference to drawings and examples, the present invention is described in detail.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the invention.
Fig. 2 is schematic view of the mounting position of the invention.
Fig. 3 is computer artificial result tail wind velocity comparison diagram.
Embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of automobile tail light air deflector, the air deflector 1 generally wedge structure, bag
Mounting surface 2 and guide face 3 are included, the air deflector 1 is arranged on the taillight 5 at automobile side rear, and the thin one end of air deflector 1 is close
Vehicle front end, thick one end is close to vehicle afterbody.The guide face 3 and both sides be provided with the chamfering 4 of arc transition.
The setting height(from bottom) of the air deflector 1 is at the position of center line of taillight 5.The air deflector 1 is installed and away from the side of taillight 5
At 1~3mm of face and rear transition flex point distance position, preferably 2mm.The air deflector 1 is fixed on vapour by way of pasting
On tail-light, do not change the structure of protocercal tail lamp, can be widely applied on existing automobile product.
As shown in figure 3, before the taillight air deflector is added, flow through the air on taillight surface slowly can separate with taillight, so
Enter the region for relativelying close to body tail surface afterwards, because automobile high-speed is moved forward, simultaneously because tail of the body profile
Reason, it is impossible to have enough air to fill up " region of no pressure " that automobile tail reach is formed, cause the pressure in the region smaller,
After vehicle body separation, therefore flow to the air-flow in the region can form a trailing vortex nearer apart from bodywork surface.Install tail additional
After lamp air deflector, due to the presence of taillight air deflector, the air-flow being initially separated originally along taillight surface is guided to remote
The region of vehicle body, the trailing vortex formed when the region of trailing vortex formation is from a distance from vehicle body than not installing taillight air deflector additional is from vehicle body
Distance it is remote, the now pressure increase at automobile back.Because after taillight air deflector is installed additional, the pressure of rear portion bodywork surface increases
Plus, and the anterior pressure of vehicle there is no change, cause the pressure difference value before and after vehicle to decrease, so the resistance of vehicle
It is smaller than not installing taillight air deflector additional.
