Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Embodiment mono-
Refer to Fig. 1 to Fig. 5, the utility model embodiment, a kind of automobile guiding device, before this automobile disturbing flow device comprises flexible variable, insurance is shouldered and aeration control device.
Wherein, before described flexible variable, the front end that is arranged at automobile is shouldered in insurance, comprising that insurance is shouldered body and is arranged at insurance shoulders the first air bag 1 before body, and be arranged at the second air bag 2 in the first air bag 1, described the first air bag 1 is the taper air bag of middle part to front protrusion, wherein, described " above " " below " is taking automobile as object of reference, the direction of automobile head indication is for above, the direction of tailstock indication is for below, wherein, the structure that the structure that body is shouldered in insurance is shouldered by inches with existing automobile front protecting is consistent. Preferably, in the present embodiment, described the first air bag and the second air bag are PVC material.
Described aeration control device comprises controller 4, gas bomb 3, in described controller 4, is integrated with magnetic valve. Described the first air bag 1, the second air bag 2 are connected in gas bomb 3 by pipeline respectively, and its middle controller 4 is for the inflation/deflation control of the first air bag 1, the second air bag 2.
In the time that the travel speed of automobile exceedes default threshold value, described controller is controlled described solenoid valve conduction, insurance before flexible variable is shouldered, to the first air bag and the inflation of the 2nd air bag. Refer to Fig. 2 and Fig. 3, the contour structures of the automobile during for unaerated, refers to Fig. 4 and Fig. 5, for insurance before described flexible variable is shouldered after inflation, and the contour structures of automobile. After visible inflation, can effectively reduce front part of vehicle front face area, thereby automobile windage coefficient is reduced, the windage while effectively reducing galloping, improves automobile fuel ecomomy.
Described the second air bag 2 is to play a supporting role, and makes the first air bag 1 have stronger anti-deformation intensity, thereby ensures in the time of galloping, and air bag can be because stream pressure is out of shape, and affects its water conservancy diversion effect.
In the present embodiment, in the time that the speed of a motor vehicle of automobile exceedes 80 ㎞/h, described controller 4 is controlled gas bomb 3 insurance before flexible variable is shouldered to inflation, and 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 the present embodiment, the upper surface of described the first air bag 1 is the curve slope tilting to front lower place, the lower surface of the first air bag 1 is horizontal plane, the upper surface of the first air bag 1 and car engine hatchcover seamlessly transit, lower surface flushes with automobile chassis, therefore, in the time of galloping, can be greater than the air-flow velocity of lower surface at the air-flow velocity of automobile upper surface, thereby produce a larger downforce, make automobile in the time running at high speed, still there is better earth-grasping force, the handling and security while ensureing galloping.
In some automobiles, automobile is integrated with pneumatically operated brake at car, pneumatically operated brake has comprised air pump and gas bomb, therefore, in one embodiment, described automobile disturbing flow device does not arrange gas bomb, in these vehicles, can directly use gas bomb in the former pneumatically operated brake source of the gas as air bag, the first air bag and the second air bag are connected in the gas bomb of pneumatically operated brake by pipeline, and by the controller control inflation/deflation of mentioning in above embodiment.
For make automobile from high-speed travel state when running at a low speed state, the air bag insuring in shouldering before described flexible variable can be packed up timely, in the present embodiment, also in described aeration control device, be provided with vacuum extractor, described the first air bag and the second air bag are connected to described vacuum extractor, when vacuum extractor is used for below the travel speed of automobile is reduced to described default threshold value, when 80 ㎞/h, vacuum extractor is just opened, extract the first air bag, gas in the second air bag, thereby the first air bag and the second air bag can be packed up.
Embodiment bis-
A kind of automobile guiding device, identical with embodiment mono-, in the present embodiment, before being provided with same flexible variable, insurance is shouldered, before described flexible variable, the front end that is arranged at automobile is shouldered in insurance, comprising that insurance is shouldered body and is arranged at insurance shoulders the first air bag before body, and is arranged at the second air bag in the first air bag, and described the first air bag is the taper air bag of middle part to front protrusion.
Be with the difference of embodiment mono-, the automobile disturbing flow device of present embodiment is only applicable to the automobile with turbo charging installation, therefore, the automobile disturbing flow device of present embodiment does not arrange gas bomb, described the first air bag and the second air bag are connected to the outlet pipe of car engine turbo charging installation, and the outlet pipe of described turbo charging installation is the gas pipeline of turbo charging installation to engine supercharging. By turbo charging installation, the first air bag and the second air bag are inflated.
In existing turbocharging automobile, turbine is generally in the time that car engine revolution exceedes certain value, and ability open turbine is to starting supercharging, and now automobile is all to travel with higher speed per hour substantially, or the process raising speed from low speed to high speed. And in present embodiment, automobile disturbing flow device just at this moment to insurance before flexible variable shoulder with flexible variable after insurance shoulder and inflate, thereby the windage while reducing galloping. In the present embodiment, save aeration control device, and directly adopt turbo charging installation to inflate and ventilating control, not only greatly reduce the weight of automobile disturbing flow device, save hardware cost, also simplified the controlling mechanism of air bag.
In sum, the utility model is by changing the shape of automobile windward side, can effectively reduce front part of vehicle front face area, the windage while reducing to run at high speed, can reduce automobile energy consumption, improve energy utilization rate, and the utility model adopts air bag as main structural material, it is simple in structure, lightweight, substantially do not 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 position and can play the effect of buffering collision of closed, the effectively pedestrian protecting function of lifting vehicle.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; 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.
