A kind of automobile rearview mirror of structure optimization
Technical field:
The present invention relates to the technical field of auto parts machinery, more specifically to a kind of vapour of structure optimizationCar rearview mirror.
Background technology:
Rearview mirror is that driver is sitting in and on driver's cabin seat, directly obtains automobile rear, side and below etc.The instrument of external information is the important composition parts on automobile. Existing rearview mirror is generally located at automobileBoth sides, it mainly contains housing and eyeglass composition, and on existing rearview mirror, be not generally provided with windscreen wiper,The parts such as rain brush, when being covered with dust all on rearview mirror, when the situation such as water smoke, affect the use of rearview mirror,In the time driving, clearing up rearview mirror has inconvenience, thereby designer is by similar automobile front wind screenWiper on glass is arranged on rearview mirror to be cleared up, but because rearview mirror area is less, and windscreen wiperSupport element on device etc. affects the sight line of rearview mirror, causes potential safety hazard.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and a kind of vapour of structure optimization is providedCar rearview mirror, it forms air curtain by wind-force is that automobile rearview mirror stops rainwater, after blowing away by wind-forceThe dust of visor minute surface or water smoke, the while can not affect the sight line of rearview mirror.
An automobile rearview mirror for structure optimization, comprises housing and the eyeglass of automobile rearview mirror, housingOn inwall, form annular boss, eyeglass is fixed on the front end face of boss, on the front end face of eyeglassAgainst the blend stop that has ' Jiong ' font, blend stop is fixed on the inwall of housing, before the housing of eyeglass surroundingOn end face, form the framework of extending forward, on the framework bottom surface of boss front side, form the leakage of bar shapedTank; In the framework of eyeglass top and housing, form some air curtain air flues and blow aqueous vapor road, air curtain gasRoad and blow aqueous vapor road and be staggered and be uniformly distributed in framework and housing;
In described framework, form the bar shaped air curtain mouth and the sweptback bar shaped that turn forward and blow waterMouthful, bar shaped air curtain mouth is connected with the front end of air curtain air flue, and the mouth of a river and the front end that blows aqueous vapor road are blown in bar shapedBe connected also relative with eyeglass front end face, on described housing, form some the first vertical air inletsPipe and the second air inlet pipe, the lower end of the first air inlet pipe is fixed on the first discharge, the second air inlet pipeLower end is fixed on the second discharge, and the second discharge and the first discharge are separately fixed at the second electromagnetismOn valve and the first magnetic valve, the second magnetic valve and the first magnetic valve are fixed on the inwall of housing and pass throughBranched pipe is fixedly connected on main tracheae.
The front end face of described housing framework is and rolls backward oblique inclined-plane.
Described the first air inlet pipe, the second air inlet pipe, the second discharge, the first discharge, the first electromagnetismValve and the second magnetic valve are all positioned at housing and are positioned at the rear side of eyeglass.
Beneficial effect of the present invention is:
It has rectified and improved the structure of rearview mirror, and the structure that realizes rearview mirror can form wind by external wind-forceCurtain and blow water-bound, thereby can stop rainwater for automobile rearview mirror, can blow away the ash of rear-vision mirror faceDirt or water smoke, rearview mirror front side stops without support simultaneously, thereby can not affect the sight line of rearview mirror.

Detailed description of the invention:
Embodiment: see shown in Fig. 1 to 6, a kind of automobile rearview mirror of structure optimization, comprises after automobileThe housing 1 of visor and eyeglass 2, form annular boss 11 on the inwall of housing 1, eyeglass 2 is solidFix on the front end face of boss 11, on the front end face of eyeglass 2 against the blend stop 3 that has ' Jiong ' font,Blend stop 3 is fixed on the inwall of housing 1, on housing 1 front end face of eyeglass 2 surroundings, forms forwardThe framework 12 of extending, forms the leak-off chute 13 of bar shaped on framework 12 bottom surfaces of boss 11 front sides;In the framework 12 of eyeglass 2 tops and housing 1, form some air curtain air flues 14 and blow aqueous vapor road 16,Air curtain air flue 14 and blow aqueous vapor road 16 and be staggered and be uniformly distributed in framework 12 and housing 1;
In described framework 12, form the bar shaped air curtain mouth 15 and the sweptback bar shaped that turn forwardBlow the mouth of a river 17, bar shaped air curtain mouth 15 is connected with the front end of air curtain air flue 14, and the mouth of a river 17 is blown in bar shapedBe connected and relative with eyeglass 2 front end faces with the front end that blows aqueous vapor road 16, moulding on described housing 1There is the lower end of some the first vertical air inlet pipe 4 and the second air inlet pipe 5, the first air inlet pipe 4 to fixOn the first discharge 8, the lower end of the second air inlet pipe 5 is fixed on the second discharge 6, the second collectionTracheae 6 and the first discharge 8 are separately fixed on the second magnetic valve 9 and the first magnetic valve 7, and secondMagnetic valve 9 and the first magnetic valve 7 are fixed on the inwall of housing 1 and are fixedly connected on by branched pipeOn main tracheae 10.
The front end face of described housing 1 framework 12 is and rolls backward oblique inclined-plane.
Described the first air inlet pipe 4, the second air inlet pipe 5, the second discharge 6, the first discharge 8,One magnetic valve 7 and the second magnetic valve 9 are all positioned at housing 1 and are positioned at the rear side of eyeglass 2.
Operation principle: the rearview mirror that the present invention is automobile, the structure that it has rectified and improved rearview mirror, is speciallyRectify and improve the structure of back-mirror housing, set up blowing conduit and corresponding additional device, its blowing slotRoad is air curtain air flue 14, bar shaped air curtain mouth 15, blow aqueous vapor road 16 and the mouth of a river 17 is blown in bar shaped, from bar shapedAir curtain mouth 15 blows out as eyeglass 2 forms air curtain, blows the mouth of a river 17 and blows out, for being eyeglass 2 from bar shapedFront end face blows down water smoke and dust, and air curtain air flue 14 can be by first with the wind that blows aqueous vapor road 16Magnetic valve 7 and the second magnetic valve 9 are controlled respectively.
