Abstract
A kind of adjustable automobile empennage is the utility model is related to, empennage covers installed in automobile trunk, and empennage can rotate up and down with the different relative D posts of speed, it is characterised in that：Empennage is provided with windage annex, and described windage annex is folding wings, and folding wings are opened or folded with rotating up and down for empennage.In galloping, empennage is rotated up reaching maximum height, while folding wings are opened therewith, increases the pressure at automobile back with this, so as to further reduce the traveling air resistance coefficient of automobile, reduces fuel consumption to a greater degree.
Description
Technical field
It the utility model is related to a kind of adjustable automobile empennage.
Background technology
Automobile tail fin is also known as automotive spoilers, and its main function is whole to the progress of vehicle body air-flow in galloping
Stream, reduce traveling windage and tailstock lift, so as to reduce fuel consumption, strengthen the riding stability of automobile.Automobile tail fin it is whole
Stream effect is only obvious in galloping, and when running at a low speed, empennage increases certain resistance, increase oil to vehicle body on the contrary
Consumption.In the prior art, more using adjustable empennage, empennage height is reduced when running at a low speed, empennage tilts during high speed, plays
Actively reduce the effect of windage.
Utility model content
Goal of the invention of the present utility model is to provide a kind of adjustable automobile empennage, and one can be entered in galloping
Step reduces air resistance coefficient；Vehicle body resistance is not increased when running at a low speed simultaneously yet.
Realize the technical scheme of the present utility model purpose：
A kind of adjustable automobile empennage, empennage cover installed in automobile boot, and empennage can be with the different relative D posts of speed
Rotate up and down, it is characterised in that：Empennage is provided with windage annex, and described windage annex is folding wings, and folding wings are with empennage
Rotate up and down and open or fold.
Folding wings are in fan-folded shape, and the upper surface of folding wings connects the bottom of empennage, and the lower surface of folding wings connects D posts.
The utility model has the advantage that：
The utility model sets up windage annex on the basis of existing adjustable automobiles empennage, and described windage annex is folding
The wing, folding wings are opened or folded with rotating up and down for empennage, and in galloping, empennage is rotated up reaching maximum
Highly, while folding wings are opened therewith, increase the pressure at automobile back with this, so as to further reduce the traveling windage system of automobile
Number, reduces fuel consumption to a greater degree.When automobile speed is relatively low, empennage, which rotates down, reaches minimum altitude, folding wings with
It is equivalent hide, to reduce the windage under low speed, so as to reduce oil consumption.The utility model folding wings are in fan-folded shape, are folded
The upper surface of the wing connects the bottom of empennage, and the lower surface of folding wings connects D posts, simple in construction, reasonable in design, is easily installed.
Brief description of the drawings
Fig. 1 is view of the utility model under galloping；
Fig. 2 is view of the utility model in the case where automobile is run at a low speed.
Embodiment
As shown in figure 1, empennage 1 covers installed in automobile trunk, empennage 1 can be with different relative 3 upper and lower turns of the D posts of speed
Dynamic to be adjusted, this is prior art.Empennage 1 is provided with windage annex, and described windage annex is folding wings 2, and folding wings 2 are in fan
Shape rugosity, the upper surface of folding wings 2 connect the bottom of empennage 1, and the lower surface of folding wings 2 connects D posts 2, and folding wings 2 are with empennage 1
Rotate up and down and open or fold.
As shown in figure 1, in galloping, empennage 1 is rotated up reaching maximum height, while folding wings 2 are therewith
Open, increase the pressure at automobile back with this, so as to further reduce the traveling air resistance coefficient of automobile.
As shown in Fig. 2 when automobile speed is relatively low, empennage 1, which rotates down, reaches minimum altitude, and folding wings 2 convert into therewith
Hide, to reduce the windage under low speed.
Exemplary description has been carried out to the utility model above in conjunction with accompanying drawing, it is clear that it is of the present utility model realization not by
The limitation of aforesaid way, if the various improvement that methodology and technical scheme of the present utility model 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 the scope of protection of the utility model
It is interior.
