Description

A kind of automobile rearview mirror windshield wiper

Technical field

The utility model relates to a kind of wiper device, particularly a kind of automobile wiper device.

Background technology

At present, the back mirror that automobile is commonly used, a lot of raindrop can drop on the eyeglass of back mirror when rainy, and on the back mirror without any the device of processing raindrop, consequently having influenced the driver watches the pedestrian of automobile back and the situation of vehicle by back mirror.Night travel particularly, it is just poorer to run into its effect of rainy situation, at automobile turning or when overtaking other vehicles, must watch the situation of back by back mirror, if back mirror is unintelligible because of top rainwater, influenced the judgement of chaufeur, just be easy to cause traffic accident.The back mirror of more existing automobiles, added the sheet that keeps off the rain in the top, though can alleviate to a certain extent on the minute surface that raindrop drop on back mirror, but add this piece sheet that keeps off the rain, influence chaufeur and watched back mirror, in addition, after automobile stops, raindrop can drop on the minute surface of back mirror equally, and chaufeur can face the unsharp problem of back mirror equally.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure, convenient and practical automobile rearview mirror windshield wiper.

The technical solution adopted in the utility model is as follows:

Windshield wiper of the present utility model, it comprises body of backsight mirror, wiper, guide rail, actuating device, described guide rail is arranged on the back mirror, described wiper comprises working position, guiding position, described wiper moves freely with respect to guide rail by the guiding position, the working position of described wiper and the minute surface of body of backsight mirror are fitted, and are connected with actuating device on the described wiper.

Owing to adopted above-mentioned mechanism, make wiper under the effect of actuating device, on guide rail, make back and forth movement, because wiper closely contacts with rear-vision mirror face, make back and forth movement phase mutual friction on rear-vision mirror face of wiper promptly to reach the effect of rear-vision mirror face being blowed rain the feasible raindrop that can clear up at any time on the back mirror, guarantee the clear of back mirror, avoid causing traffic accident because of raindrop are unintelligible because of back mirror.This utility model can make that chaufeur is the work of may command windshield wiper by be connected control with automobile power source in car, thereby convenient and practical.The said structure parts are few, and are simple in structure, can promote at automotive field.

Described actuating device comprises DC motor, screw mandrel, and described wiper is rotatably connected on the screw mandrel, and described DC motor is connected with arbitrary end of screw mandrel.

Adopt said structure, the rotating of DC motor drives the screw mandrel rotation, and the junction of wiper is set to the screw thread that cooperates with screw mandrel, makes screw mandrel drive wiper make back and forth movement on guide rail.

Described actuating device comprises DC motor, crank, connecting rod, and described connecting rod one end is connected with wiper, the other end and crank connecting link, described electrical motor and crank connecting link.

Adopted above-mentioned brace and connecting rod framework, actuating device can adopt the electrical motor of unidirectional rotation, makes wiper to make back and forth movement on guide rail under the effect of connecting rod.

Described actuating device is an electric pushrod, and the push rod of described electric pushrod is connected with wiper.

Owing to adopt above-mentioned electric pushrod structure, make mechanism more simple, integral structure is littler, and electric pushrod starts, and push rod promotes wiper and make back and forth movement on guide rail, and wiper also carries out the cleaning of raindrop to rear-vision mirror face in this process.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:

1, these scheme parts are few, simple in structure, can promote at automotive field;
