Abstract
The utility model relates to a diversion and resistance reduction structure for an automotive bottom. The diversion and resistance reduction structure for the automotive bottom comprises a front wheel cover and a diversion plate which is arranged at the lower portion of the front edge of the wheel cover; the front edge of the wheel cover is connected with a lower guard plate; and the lower edge of the wheel cover is connected with an automotive body bottom plate. According to the diversion and resistance reduction structure for the automotive bottom, the diversion plate is arranged on the lower portion of the front edge of the front wheel cover, so that air flows from a front fender guard and a motor lower guard plate are performed flow separation in advance on a windward side of the diversion plate, disturbance and rectification are performed on the bottom airflows, time for the airflows entering into the front wheel cover is postponed, and wind resistance the front wheel bears is reduced.
Description
Technical field
The utility model relates to the moving annex of automobile car spirit, and the resistance structure falls in the water conservancy diversion that relates in particular to the automobile bottom.
Background technology
In the designing and developing of modern manned vehicle, except from adopting airflow design to reduce the windage of car load to overall shape, turbulent flow at the bottom of also weakening the automobile car from the angle at increase pneumatic accessories at the bottom of the automobile car, and then the turbulence intensity of reduction automobile bottom and the resistance of car load, improve the fuel economy of car load with this.
The shape of pneumatic accessories is fitfull, and size is not fixed, and the installation site also is flexible and changeable.For example, the spoiler of the following backplate of automobile front chamber, automobile tail, the closing plate at the bottom of the automobile car.These its purposes of thin and light part all are that the air-flow of automobile bottom is implemented valve action, make that with this air-flow at the bottom of car is even more, stable, reduce the generation of eddy current, make streamline reach unanimity.Simultaneously also be by improving car spirit stream speed with reduce car load suffered from the static pressure at the bottom of the car, and then reduce automobile suffered aerodynamic lift when running at high speed, the steady characteristic of behaviour when improving the running at high speed of car load.
But the front-wheel wheel cover of present automobile is not owing to there is guide functions, when air-flow moves to the front-wheel leading edge from the automobile front beam bottom, lose attachment and be fed directly in the wheel cover of front-wheel, in the wheel effect downstream fluidised form disorder that rotatablely moves, increased the suffered windage of wheel suddenly.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned defective, and the resistance structure falls in the water conservancy diversion that provides a kind of air motion to automobile bottom to play guiding function, enters disorderly air-flow in the front-wheel wheel cover with reduction.
The technical scheme that its technical matters that solves the utility model adopts is: provide the water conservancy diversion of a kind of automobile bottom to fall the resistance structure, the wheel cover that comprises front-wheel, described wheel cover leading edge links to each other with following backplate, the trailing edge of wheel cover links to each other with body bottom panel, also comprises the deflecting plate that is arranged on wheel cover leading edge bottom.
Described deflecting plate and wheel cover are structure as a whole.
Described deflecting plate is arranged on described wheel cover leading edge and described down between the backplate.
The thickness of described deflecting plate is 1mm ~ 2mm.
The surface of described deflecting plate is curved surface.
The utility model compared with prior art, beneficial effect is: the wheel cover leading edge bottom at front-wheel is provided with deflecting plate, can so that in the deflecting plate windward side burbling takes place in advance from the air-flow of front bumper and engine lower guard board, the air motion of bottom disturbance and rectification have been implemented, delay to enter the time in the front-wheel wheel cover, reduced the suffered windage of front-wheel.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is structural representation of the present utility model;
The mounting structure scheme drawing of resistance structure falls in Fig. 2 for water conservancy diversion of the present utility model;
Fig. 3 is the local enlarged diagram of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the resistance structure falls in the water conservancy diversion of a kind of automobile bottom, the wheel cover 1 that comprises front-wheel 2, wheel cover 1 leading edge links to each other with following backplate 4, the trailing edge of wheel cover 1 links to each other with body bottom panel 5, key point of the present utility model is: also be provided with deflecting plate 3 in wheel cover 1 leading edge bottom, and deflecting plate 3 is arranged between wheel cover 1 leading edge and the following backplate 4, extends to the below of wheel cover simultaneously.As shown in Figure 3, a kind of structural representation of deflecting plate is the cuboid deflecting plate, and its thickness is 1mm ~ 2mm, and the surface of deflecting plate is curved surface, can certainly be the deflecting plate of other shapes.The resistance structure falls in this water conservancy diversion, can be so that from the car spirit of front bumper and engine lower guard board stream, burbling takes place in windward side at deflecting plate in advance, air motion to the bottom plays guiding function, make air-flow flow to rear at the bottom of the car from the wheel both sides, reduce the air flow rate that enters in the front-wheel wheel cover, delayed air-flow and entered the interior time of front-wheel wheel cover, reduced the suffered windage of front-wheel.
Deflecting plate 3 of the present utility model is structure as a whole with wheel cover 1, has made things convenient for installation.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection domain of the present utility model.
