Description
Technical field
The utility model belongs to automobile rearview mirror technical field, is specifically related to a kind of Water scraper for car rearview mirror.
Background technology
Automobile rearview mirror is the indispensable parts of vehicle safety travel, the deficiency of automobile rearview mirror now:
Current automobile rearview mirror can normally use in fine day situation and when rear-vision mirror face attachment is less, but rainwater weather and rear-vision mirror face attachment more time, back mirror visual effect is had a greatly reduced quality, need the manual uninterrupted wiping rear-vision mirror face of people, remove rainwater or attachment, the normal function of back mirror is realized with this, otherwise have a strong impact on chaufeur observes tailstock portion and body side driving sight by back mirror, very easily because of back mirror blurred vision or unintelligible problem, to chaufeur doubling, overtake other vehicles and bring very large difficulty, cause the generation of traffic accident, operation hidden danger is brought to chaufeur.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Water scraper for car rearview mirror, has the advantages that structure is simple, economical and practical.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Water scraper for car rearview mirror, includes electrical motor, and the power end of electrical motor is connected with worm and gear reducing gear; Worm and gear reducing gear is connected with pin wheel; Swing arm is provided with pin wheel near worm and gear reducing gear end, is provided with driving lever from the one end away from worm and gear reducing gear; Driving lever rotates thus complete cycle revolution in the U-lag arranged on straight line sheave along with swing arm, and then promotes straight line sheave sway; Straight line sheave is also provided with semi-round pin wheel rolling groove, pin wheel rolling groove and U-lag interval are arranged; The bottom front of straight line sheave is provided with wiper arm.
Described pin wheel is a semicircular structure.
Described straight line sheave is fixedly connected with wiper arm.
The transmission shaft front end of described electrical motor is provided with support.
Described electrical motor adopts reversible type DC motor.
Described U-lag quantity is odd number, and the quantity of pin wheel rolling groove 7 is even numbers, and a pin wheel rolling groove is disposed between two U-lags.
The beneficial effects of the utility model are:
Adopt reversible type DC motor, the gyroscopic movement of pin wheel is become the rectilinear movement of wiper arm on straight line sheave, realize the object striking off rainwater.Have the following advantages:
1) structure is simple, flexible:
Water scraper for car rearview mirror power pack section is reversible type DC motor, and running part worm and gear reducing gear, straight line sheave, enforcement division is divided into wiper arm.From power pack section to the mechanism performed corresponding to part, all structure is simple, and volume compact, can be built between the mirror shell of automobile rearview mirror and guard shield.At rainwater weather, when back mirror adhering to rainwater, namely can press back mirror wiper switch, actuating motor, adopt 3 brush configurations to facilitate speed change.Intermittent time is controlled by intermittent duty relay, the return switch contact of motor and the charging/discharging function of relay resistance capacitance is utilized to make wiper according to some cycles, coordinate amount of rainfall number, carry out adjustable gear to sweep, the rotating speed of electrical motor increases torsion effect driving swing arm through the deceleration of worm and gear, swing arm drives straight line sheave, straight-line groove wheel drives the wiper arm be arranged on straight-line groove to scrape back mirror, rainwater on timely cleaning back mirror, recover the visibility of back mirror, ensure that chaufeur passes through back mirror, the driving sight of observing tailstock portion and body side is in normal condition, effectively realize the doubling of chaufeur or function of overtaking other vehicles, easy to use.
2) economic and practical:
The power pack section of Water scraper for car rearview mirror, reversible type DC motor uses extensively, and general price has dozens of yuan to more than 100 yuan not etc.Running part is mechanical device, and general price does not exceed 100 yuan yet, therefore can meet the cost-effectiveness requirement of user.

Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further detail.
See Fig. 1,2,3,4, a kind of Water scraper for car rearview mirror, includes electrical motor 1, and the power end of electrical motor is connected with worm and gear reducing gear 2; Worm and gear reducing gear 2 is connected with pin wheel; Swing arm 3 is provided with pin wheel 4 near worm and gear reducing gear 2 end, is provided with driving lever 5 from the one end away from worm and gear reducing gear 2; Driving lever 5 rotates thus complete cycle revolution in the U-lag 6 arranged on straight line sheave 8 along with swing arm 3, and then promotes straight line sheave sway; Straight line sheave 8 is also provided with semi-round pin wheel rolling groove 7, pin wheel rolling groove 7 and U-lag 6 interval are arranged; The bottom front of straight line sheave 8 is provided with wiper arm 10.
Described pin wheel is a semicircular structure.
Described straight line sheave 8 is fixedly connected with wiper arm 10.
The transmission shaft front end of described electrical motor is provided with support 9.Because transmission shaft front end is provided with worm and gear reducing gear 2, swing arm 3, pin wheel 4 and driving lever 5, support is for supporting motor worm worm speed-down gear 2, swing arm 3, pin wheel 4 and driving lever 5.
