Description
Technical field
The utility model belongs to technical field of automobile parts, relates to a kind of automotive air intake grid.
Background technology
An automobile whether attractive in appearance, not only to see it the outward appearance lines, also to know each manufacturer simultaneously and be the ensoul place of theory of its product, wherein the automotive air intake grid is best embodiment representative, it both can be used as the vehicle decorative part, can become " family's types of facial makeup in Beijing operas " of automobile vendor again, like the car personage as long as automobile face at a glance, just know that their teachers go out He Men.
Air-inlet grille is related to the effective wind area of automotive front windward side pressure and car load when influencing moulding, it is the starting point in automotive interior flow field, and is bigger to the aerodynamic drag influence of automobile.Driving engine can make the radiator water temperature rise in the course of the work, when using the fan auxiliary heat dissipation, radiator is arranged on the air-inlet grille back, makes radiator equal the wind area of radiator over against the air inlet area of air-inlet grille and general air-inlet grille.Automobile in the process of moving, air flows backward and acts on the radiator by air-inlet grille, the air-flow that heat radiation back temperature raises from the engine case rear near the position of windscreen, also have automobile below flow backward, heat is emitted.Therefore, air-inlet grille is most important for an automobile.
China's utility application (201020247064.9) has been announced a kind of automotive air intake grid, this air-inlet grille is rectangular arcuation, its middle part is for being provided with the intake section of air inlet through hole, the both sides of intake section are the ornamental portion of sealing, the width of described intake section equals the width of automobile radiators, in the middle of according to automobile condenser and radiator windward side the orthogonal projection of air-inlet grille being divided into grid and two side areas, then two side areas is made sealing state, implement easily, increase integral vehicle cost hardly.But the ventilation inlet size of this kind air-inlet grille is fixed, when automobile is in idling or low speed driving, because wind-force is less, therefore need bigger ventilation inlet, and automobile is in when running at high speed, and intake is enough, and too big air-inlet grille but can be caused the increase of resistance.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of automotive air intake grid, and this automotive air intake grid can be regulated the ventilation inlet size of air-inlet grille according to the speed of automobile.
The purpose of this utility model can realize by following technical proposal: a kind of automotive air intake grid, be arranged on the automobile front beam, comprise the grid body, it is characterized in that, grid body medial surface be provided with can the grating body baffle plate, the inboard of described grid body is fixed with a chute along the lower edge, the lower edge sliding plug of above-mentioned baffle plate also is provided with on the described car body and can drives the control mechanism that baffle plate moves along chute in chute.
The grid body is arranged on the front bumper, and over against the water tank of automobile, when baffle plate covered the grid body, gas can't enter from the grid body; When automobile stopped, control mechanism control baffle plate covered whole grid body, prevents that foreign material, rainwater etc. from entering the grid body; When automobile was in idling or low speed driving, control mechanism control baffle plate moved along chute, and opens fully, makes the grid body have maximum incoming air area; When automobile is in when running at high speed, the suitable incoming air area that reduces the grid body of control mechanism control baffle plate, thus reduce resistance.
In above-mentioned automotive air intake grid, described baffle plate comprises right baffle-plate and right baffle plate, and the length of described chute is the twice of grid body lower edge length.Right baffle-plate and right baffle plate are symmetrical arranged, and the length of chute is the twice of grid body lower edge length, guarantee that right baffle-plate and right baffle plate make the grid body have maximum incoming air area after two side shiftings.
In above-mentioned automotive air intake grid, described control mechanism comprises left motor and right motor, described left motor is connected with right baffle-plate, right motor is connected with right baffle plate, be equipped with a tooth bar in the upper edge of right baffle-plate and right baffle plate, be fixed with gear on the output shaft of left side motor and right motor, described left motor is meshed by wheel and rack with right motor and drives right baffle-plate and right baffle plate.Rotate by motor driven gear, the horizontal movement of gear driven tooth bar, simple in structure, stability is high.
In above-mentioned automotive air intake grid, described left motor all is connected with controller by electric wire with right motor, and described controller is connected with tachogenerator by electric wire.Tachogenerator feeds back to controller with the moving velocity of automobile, and controller rotates according to the size control motor of speed, makes the grid body have a suitable incoming air area.
In above-mentioned automotive air intake grid, also be provided with a press strip in the described front bumper, the medial surface of described press strip transverse fit right baffle-plate and right baffle plate, the two ends of press strip are connected on the front bumper.The road conditions of jolting can occur during running car, and baffle plate be had a bigger pressure when running at high speed, press strip can make baffle plate keep stable.
Compared with prior art, this automotive air intake grid has the following advantages:
1, because the installed inside of grid body has right baffle-plate and right baffle plate, this two baffle plate can be controlled the incoming air area of grid body, the resistance that reduces automobile that therefore can be in good time according to the speed of automobile.
Right baffle-plate and right baffle plate can be closed the grid body when 2, stopping owing to automobile, therefore can prevent that foreign material, rainwater etc. from entering the grid body.
3, because the incoming air area of grid body can be regulated automatically by controller, need not manual regulation, therefore easy to use, the automatization level height.
