Abstract
The invention discloses a windscreen wiper, which comprises a stepping motor system, a primary synchronous pulley, a synchronous belt, a secondary synchronous pulley, a wiper arm mounting shaft and a wiper arm, wherein the stepping motor system is composed of a stepping motor, a controller and an operating panel; the primary synchronous pulley is fastened with the main shaft of the stepping motor; the synchronous belt is matched with the primary and the secondary synchronous pulleys; the wiper arm mounting shaft is fastened with the secondary synchronous pulley; and the wiper arm is fastened with the wiper arm mounting shaft. The windscreen wiper is characterized in that the stepping motor is a rotating stepping motor; the controller is an integrated control driving system; the primary and the secondary synchronous pulleys are cylindrical straight-teeth gears; the driving belt is a straight-teeth driving belt; the primary and the secondary synchronous pulleys and the synchronous belt are the same in modulus; and the speed ratio is adjusted by changing the teeth number of the pulleys. By the program of the controller, the stepping motor is controlled to stop for a certain time during back and forth movement, and the program is circulated to facilitate the windscreen wiper to do useful work in the back and forth movement process, so that the glass and wiper are protected, the service life is prolonged and the wiping angle can be adjusted casually.
Description
Technical field
The present invention relates to the vehicular spare parts technical field, specifically is a kind of wiper.
Background technology
Existing wiper is generally permanent magnet motor and drives worm screw, slowed down by the worm drive worm gear, by worm drive connecting rod, fork (also claiming four-bar linkage), scrape horse by the connecting rod mechanism drive and come and go rotation, the scraping blade of scraping on the horse sweeps glass surface, and control is divided into intermittently shelves, slow shelves, fast shelves.
But there is following shortcoming in prior art:
1, because only in a direction rotation of electrical motor, drivening rod makes to scrape in the horse two-way process can only make continuous movement, when rainfall hour (with intermittently shelves and slow shelves time), the Essential Action that scraping blade sweeps glass is only for once, and action be one past, one return twice, useful work is about 1/2nd;
2, the less use of rainfall is intermittently when shelves and slow shelves, scraping blade toward process in, so that rainwater is scraped totally substantially, in the process of returning that is right after rainwater seldom, scraping blade rubs with glass and aggravates, and has shortened the service life of glass and scraping blade.
3, scraping horse sweeps angle and can not regulate after wiper installs.
Summary of the invention
The problem to be solved in the present invention is; a kind of wiper is provided; make it not make continuous movement toward with the process returned the time; be intermittent moment; and length of the halt can be regulated, and making wiper all is being useful work toward what do when returning, cover glass and scraping blade; prolong its service life, scrape horse and sweep angle and can regulate.
Technical scheme of the present invention is, a kind of wiper with following structure is provided, comprise stepping motor system, main synchronous pulley, Timing Belt, secondary synchronous pulley, scrape the horse installation shaft, scrape horse, stepping motor system is comprised of stepping motor, controller, operating panel; Described main synchronous pulley and stepping motor main shaft are fastenedly connected, Timing Belt and main synchronous pulley, secondary synchronous pulley bearing fit, and scraping blade installation shaft and secondary synchronous pulley are fastenedly connected, and scrape horse and scrape the horse installation shaft to be fastenedly connected; It is characterized in that: described stepper motor is rotary-type stepper motor, controller is integrated control, drive system, operating panel is installed in the place that steering wheel or console are convenient to driver's operation, described main synchronous pulley is cylindric straight-tooth gear, described secondary synchronous pulley is cylindric straight-tooth gear, described driving band is the straight-tooth driving band, described main synchronous pulley, secondary synchronous pulley, Timing Belt three modulus is identical, can come adjusting speed ratio by the number of teeth that changes main synchronous pulley and secondary synchronous pulley, the described horse installation shaft of scraping is installed on the vehicle body under the automobile front glass, and the described horse of scraping is used for installing, the transmission scraping blade.
After adopting above structure, the present invention compared with prior art has the following advantages:
Work out required program by controller, controller control step motor rotation is transferred to and scrapes on the horse; cover in past program, rest behind the required time, move the program of returning; after the program of returning is covered; rest again after the required time, the above program that circulates, thus make wiper toward sweeping rainwater when returning operation; making wiper all is being useful work toward what do when returning; cover glass and scraping blade prolong its service life, scrape horse and sweep angle and can regulate arbitrarily by program design.
Description of drawings
Accompanying drawing is the scheme drawing of wiper of the present invention
As shown in the figure: 1, stepping motor system 2, main synchronous pulley 3, Timing Belt 4, secondary synchronous pulley 5, scrape horse installation shaft 6, scrape horse 101, controller 102, operating panel 103, stepper motor main shaft
The specific embodiment
Be described further below in conjunction with the drawings and specific embodiments
According to scraping horse (6) running required angle and past, intermittent time between returning, and different rainfall sizes, weave corresponding program and storage with controller (101), when needs are scraped horse (6) running, press the upper corresponding switch of operating panel (102) according to the rainfall size, controller (101) accesses corresponding program, control step motor (1) operation, stepping motor (1) drives main synchronous pulley (2), by Timing Belt (3) transmission synchronous pulley (4), secondary synchronous pulley (4) drives and scrapes horse installation shaft (5), scrapes horse installation shaft (5) drive and scrapes horse (6) operation.
Below only the preferred plan of example of the present invention is described, but can not be interpreted as it is limitations on claims.The present invention not only is confined to above example, and its concrete structure has allowed multiple variation, also can use control lever commonly used on the automobile instead such as: the operating function of operating panel (102) and realize, more than these change all within protection scope of the present invention.
