Detailed description of the invention
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Embodiment one
Refer to Fig. 1 to Fig. 5, the utility model embodiment, after a kind of automobile, guiding device is shouldered in insurance, and after this automobile disturbing flow device comprises flexible variable, insurance is shouldered and aeration control device.
Wherein, after described flexible variable, the rear end being arranged at automobile is shouldered in insurance, comprise insuring to shoulder body and be arranged at insurance and shoulder body the first air bag 1 below, and the second air bag 2 be arranged in the first air bag 1, described first air bag 1 is the taper air bag of middle part to rearward projection, and upper surface and the lower surface of described first air bag 1 are curve slope.Wherein, described " below " take automobile as object of reference, and the direction of automobile head indication is above, and the direction of tailstock indication is below, and wherein, the insurance structure of shouldering body is with to insure the structure shouldered after existing automobile consistent.Preferably, in the present embodiment, described first air bag and the second air bag are PVC material.
Described aeration control device comprises controller 4, gaholder 3, is integrated with electromagnetic valve in described controller 4.Described first air bag 1, second air bag 2 is connected to gaholder 3 respectively by pipeline, and its middle controller 4 controls for the inflation/deflation of the first air bag 1, second air bag 2.
When the moving velocity of automobile exceedes default threshold value, described controller then controls described solenoid valve conduction, shoulders insurance after flexible variable, namely to the first air bag and the inflation of the 2nd air bag.Refer to Fig. 2 and Fig. 3, be the contour structures of automobile during unaerated, refer to Fig. 4 and Fig. 5, after inflation is shouldered to insurance after described flexible variable, the contour structures of automobile.Vehicle tail profile more streamline can be made after visible inflation, thus automobile windage coefficient is reduced, effectively reduce windage during galloping, improve automobile fuel ecomomy.
Described second air bag 2 is played a supporting role, and makes the first air bag 1 have stronger anti-deformation intensity, thus ensure that, when galloping, air bag can not be out of shape because of stream pressure, affect its water conservancy diversion effect.
In the present embodiment, when the speed of a motor vehicle of automobile is more than 80 ㎞/h, after described controller 4 controls gaholder 3 pairs of flexible variables, inflation is shouldered in insurance, and namely described default threshold value is 80 ㎞/h.And in some other embodiments, the arbitrary value in when described default threshold value can be 80 ㎞/h ~ 120 ㎞/h.
In some automobiles, automobile is integrated with pneumatically operated brake at car, pneumatically operated brake includes air pump and gaholder, therefore, in one embodiment, described automobile disturbing flow device does not arrange gaholder, in these vehicles, can directly use the gaholder in former pneumatically operated brake as the source of the gas of air bag, namely the first air bag and the second air bag are connected to the gaholder of pneumatically operated brake by pipeline, and control inflation/deflation by the controller mentioned in above embodiment.
During for making automobile from high-speed travel state to low-speed running state, insure the air bag in shouldering after described flexible variable can pack up timely, in the present embodiment, also in described aeration control device, be provided with vacuum extractor, described first air bag and the second air bag are connected to described vacuum extractor, vacuum extractor is used for when the moving velocity of automobile is reduced to below described default threshold value, namely during 80 ㎞/h, vacuum extractor is just opened, extract the first air bag, gas in second air bag, thus the first air bag and the second air bag are packed up.
Embodiment two
After a kind of automobile, guiding device is shouldered in insurance, identical with embodiment one, in the present embodiment, after being provided with same flexible variable, insurance is shouldered, after described flexible variable, the rear end being arranged at automobile is shouldered in insurance, comprise insuring to shoulder body and be arranged at insurance and shoulder body the first air bag below, and be arranged at the second air bag in the first air bag, described first air bag is the taper air bag of middle part to rearward projection.
Be with the difference of embodiment one, the automobile disturbing flow device of present embodiment is only applicable to the automobile with charging turbine set, therefore, the automobile disturbing flow device of present embodiment does not arrange gaholder, described first air bag and the second air bag are connected to the vent pipe of car engine charging turbine set, and the vent pipe of described charging turbine set and charging turbine set are to the gas line of engine supercharging.By charging turbine set, the first air bag and the second air bag are inflated.
In existing turbo-charging automobile, turbine is generally when car engine revolution exceedes certain value, and just open turbine is to starting supercharging, and now automobile is all travel with higher speed per hour substantially, or raising speed from low speed to high speed process.And in present embodiment, automobile disturbing flow device shoulders inflation to insurance after flexible variable just at this moment, thus windage when reducing galloping.In the present embodiment, the aeration control device saved, and directly adopt charging turbine set to carry out inflating and ventilating control, not only greatly reduce the weight of automobile disturbing flow device, save hardware cost, also simplify the controlling mechanism of air bag.
In sum, the utility model is by changing the shape of automobile windward side, effectively can reduce the windage of vehicle tail, can automobile energy consumption be reduced, improve energy utilization rate, and, the utility model adopts air bag as main structural materials, its structure is simple, lightweight, does not substantially increase the complete vehicle weight of automobile; Further, the structure based on air bag has good flexibility characteristics, is arranged on headstock insurance and shoulders the effect that buffering collision of closed can be played in position.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
