Abstract
The utility model is related to a kind of taillight for reducing air resistance coefficient, it is characterised in that：In automobile tail light（2）A trapezoidal projection is provided with airflow on surface separation point position（21）；The trapezoidal projection（21）It is included in the taillight（2）At airflow on surface separation point position, along perpendicular to vehicle body（1）A direction trapezoidal faces stretched laterally, the taillight（2）Anterior face seamlessly transitted so as to form the trapezoidal projection with the upper bottom of the trapezoidal faces and two waists（21）.The taillight（2）Anterior face seamlessly transitted with the upper bottom of the trapezoidal faces and two waists and form respectively transition face, two waists of the trapezoidal faces and upper bottom and the angle of corresponding transition face are 90 degree.It is more thorough that the utility model causes that air-flow is separated, it is to avoid fraction is introduced into trailing vortex area, and pressure difference reduces before and after vehicle body, therefore vehicle resistance reduces.And the utility model is not related to the change of vehicle projected area, therefore wind resistance coefficient of whole vehicle can be reduced, and can make wind resistance coefficient of whole vehicle reduction by 0.002.
Description
Technical field
The utility model belongs to automobile technical field, and in particular to a kind of taillight for reducing air resistance coefficient.
Background technology
With the development of automotive aerodynamics, its aerodynamic performance is increasingly paid attention in car conour design, well
Aerodynamic design help to be lifted the dynamic economicses etc. of vehicle other performances, and this design is had begun in car
Embodied in each several part details of body.
The windage of automobile is exactly an important factor for influenceing automotive performance, and the low windage of automobile is designed to effectively
Improve dynamic economicses, max. speed of vehicle etc..Current car conour design, from vehicle general outline to each component detail
All make every effort to make vehicle windage minimum, generally, the comparing of the taillight surface design of automobile is round and smooth, even if some taillight surfaces devise
Some features, but it is unreasonable due to what is designed, do not have the effect for reducing windage.
Utility model content
The utility model devises a kind of taillight for reducing air resistance coefficient, which solves before vehicle modeling is not influenceed
How put reduces the problem of wind resistance coefficient of whole vehicle by transforming automobile tail light.
In order to solve above-mentioned technical problem, the utility model employs following scheme：
A kind of taillight for reducing air resistance coefficient, it is characterised in that：Set at automobile tail light airflow on surface separation point position
There is a trapezoidal projection；The trapezoidal projection is included at the taillight airflow on surface separation point position, along perpendicular to vehicle body direction to
The stretched trapezoidal faces in outside, the anterior face of the taillight is seamlessly transitted so as to shape with the upper bottom of the trapezoidal faces and two waists
Into the trapezoidal projection.
Further, the anterior face of the taillight is seamlessly transitted and form respectively with the upper bottom of the trapezoidal faces and two waists
Face is crossed, two waists of the trapezoidal faces and upper bottom and the angle of corresponding transition face are 90 degree.
Further, the width at bottom is 104mm in the trapezoidal faces, and the width of the trapezoidal faces bottom is 127mm, the ladder
The height in shape face is 22mm.
The taillight that air resistance coefficient can be reduced has the advantages that：
（1）The utility model on the basis of automobile moulding basic in itself and structure is not changed, by automobile tail light
Profile does the change of small range, effectively reduces wind resistance coefficient of whole vehicle, improves the aerodynamic performance of vehicle, simple structure, into
This is cheap, it is easy to popularization and application.
（2）The utility model designs a projection with certain profile in taillight airflow on surface separation point position so that gas
Flow separation is more thorough, it is to avoid fraction is introduced into trailing vortex area, and pressure difference reduces before and after vehicle body, therefore vehicle resistance reduces.And should
Utility model is not related to the change of vehicle projected area, therefore wind resistance coefficient of whole vehicle can be reduced, and contrast is calculated using forward and backward model
As a result, wind resistance coefficient of whole vehicle reduction by 0.002 can be made.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
Fig. 1 to Fig. 4 shows a kind of taillight for reducing air resistance coefficient.According to the result that fluid emulation is calculated, tail is determined
The airflow on surface separation point position of lamp 2, does one trapezoidal raised 21, i.e., on the position edge in the airflow on surface separation point position of automobile tail light 2
Perpendicular to the direction of vehicle body 1, stretched trapezoidal faces laterally, specific size as shown in Figure 2, then by the anterior face of taillight 2
Seamlessly transitted so as to form one trapezoidal raised 21 with two waists of trapezoidal faces and upper bottom, while keeping transition face and two corresponding waists
It it is 90 degree with the angle at upper bottom.Purpose is so that the airflow on surface of car light 2 is separated fully herein, it is to avoid will the non-separation bubble in part
The rear portion of vehicle body 1 is introduced, reduces automobile tail tubulence energy, trailing vortex size has also reduced, the pressure at the rear portion of vehicle body 1 relatively uses the reality
Increased before with new, because the anterior pressure of vehicle body 1 is not changed in, front and rear pressure difference reduces, therefore vehicle resistance reduces.Because of the practicality
It is new not to be related to the change of vehicle projected area, therefore wind resistance coefficient of whole vehicle can be reduced, contrast calculates knot using forward and backward model
Really, wind resistance coefficient of whole vehicle reduction by 0.002 can be made.
As shown in figure 1, the utility model can reduce structural representation of the taillight of air resistance coefficient on vehicle body, including vehicle body
1st, taillight 2 and rear windshield 3, one trapezoidal raised 21 is done in the airflow on surface separation point position of automobile tail light 2.
As shown in Figure 2, the width a at bottom is 104mm in trapezoidal faces, and the width b of trapezoidal faces bottom is 127mm, trapezoidal faces
H high be 22mm.
As shown in Figure 3 and Figure 4, it is the left view and rearview of the taillight that the utility model can reduce air resistance coefficient, this reality
Apply in example by taking the taillight of car right side as an example.
Exemplary description is carried out to the utility model above in conjunction with accompanying drawing, it is clear that realization of the present utility model is not received
The limitation of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improve and design of the present utility model and technical scheme are directly applied into other occasions, in protection domain of the present utility model
It is interior.
