Description
Technical field
The utility model relates to a kind of wiper, be specifically related to a kind of windscreen wiper intermittently with hydro-peening coordinated control circuit.
Background technology
Vehicle wiper motor commonly used at present is generally the high low speed direct current permanent magnet motor that carries the return on-off signal, permanent magnetism wiper electrical motor adopts 3 brush configurations to make things convenient for speed change, relative angle is that two brushes of 180 degree are realized low speed, and relative angle is that two brushes of 90 degree are realized at a high speed.
Being installed in the general and worm and gear mechanics of wiper electrical motor on the front windshield is made of one, the effect of worm-and-wheel gear is to slow down to increase to turn round, its output shaft drives four-bar linkage, continuous rotary motion is changed into the motion that swings by four-bar linkage.The scraping blade adhesive tape of wiper is directly to remove the instrument of rainwater on glass and dirt, and the scraping blade adhesive tape is pressed to glass surface by spring, and its lip must be consistent with the cooperation of glass angle, can reach desired performance.
The windscreen wiper intermittent time is controlled by intermittent duty relay, utilizes the function that discharges and recharges of the return switch contact of motor and relay resistance capacitance wiper to be scraped according to some cycles sweep.Wiper control turn-knob is arranged on the automobile combined switch handle generally speaking, be provided with low speed, at a high speed, 3 gears intermittently, the handle top is the scrubber button switch, pressing switch has the daily water ejection, cooperates wiper washing Windshield.Scrubber system is a very common device on the present automobile, it is made up of reserve tank, water pump, water-supply-pipe, water jet, wherein reserve tank generally is 1.5 liters～2 liters a plastic tank, water pump is a kind of miniature electric centrifugal pump, by it the daily water of reserve tank are transferred to water jet, through the squeezing action of 2～4 water jets daily water are divided into tiny jet and spray to Windshield, cooperate wiper to play the effect of cleaning Windshield.
The type of drive of rain shaving electrical machine is generally by the power supply of the high speed of wiper combined switch direct control wiper motor/low speed, the common port of wiper motor and the metal case bonding that directly links to each other; Windscreen wiper is intermittently controlled by a slug relay with the hydro-peening coordinated control, three reeds of worm gear are that the intermittent time of control windscreen wiper return is controlled by intermittent duty relay, utilize the function that discharges and recharges of the return switch contact of motor and relay resistance capacitance wiper to be scraped according to some cycles sweep.The shortcoming of this traditional control method be the windscreen wiper combined switch intermittence shelves and OFF shelves parts comparatively complicated, combined switch will bear bigger rush of current, rain shaving electrical machine in-to-in return switch also will bear bigger rush of current.
The utility model content
In view of this, the purpose of this utility model provide a kind of windscreen wiper intermittently with hydro-peening coordinated control circuit, it utilizes MCU to carry out Based Intelligent Control, realize windscreen wiper intermittently with the hydro-peening coordinated control, provide cost savings.
To achieve these goals, the utility model is by the following technical solutions:
A kind of windscreen wiper intermittently with hydro-peening coordinated control circuit, wherein, windscreen wiper intermittently comprises MCU with hydro-peening coordinated control circuit, relay, water spray motor and rain shaving electrical machine, described MCU connects wiper combined switch and relay, the other end of relay connects the low speed control end pin and the hydro-peening button switch of rain shaving electrical machine, the High-speed Control end pin of rain shaving electrical machine is connected with the wiper combined switch, rain shaving electrical machine is connected with the water spray motor, the water spray motor connects the hydro-peening button switch, MCU is connected with the water spray motor with the hydro-peening button switch respectively, and described wiper combined switch is a single pole multiple throw.
Further, described windscreen wiper intermittently also comprises insurance and combined switch with hydro-peening coordinated control circuit, and described insurance is connected wiper combined switch, hydro-peening button switch and rain shaving electrical machine respectively with combined switch.
The beneficial effects of the utility model are:
The utility model can reduce and introduce signal high speed and low-tach wire harness by holding pin to detect the mode of operation of rain shaving electrical machine with rain shaving electrical machine low speed control end pin bonded assembly MCU, saves controller cost and wire harness cost; The wiper combined switch is a single pole multiple throw, has guaranteed rain shaving electrical machine intermittence, low speed, can not work simultaneously at a high speed; Water spray interlock function is to press the back rain shaving electrical machine in spraying button will hang brush continuously 2～3 times, be operated in intermittence, low speed, be out-of-action at a high speed at wiper, high speed, the low speed of having avoided making rain shaving electrical machine is powered simultaneously and is produced the partial short-circuit of the inner winding of rain shaving electrical machine, the problem that makes the rain shaving electrical machine premature aging easily or burn.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification sheets or the accompanying drawing.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model.
The specific embodiment
As shown in Figure 1, windscreen wiper intermittently comprises MCU2, relay 3, water spray motor 5 and rain shaving electrical machine 6 with hydro-peening coordinated control circuit, MCU2 connects the shelves and relay 3 at intermittence of wiper combined switch 1, the other end of relay 3 connects the low speed control end pin and the hydro-peening button switch 4 of rain shaving electrical machine 6, and the High-speed Control end pin of rain shaving electrical machine 6 is connected with the high speed gear of wiper combined switch 1; MCU2 is connected with the switch of rain shaving electrical machine 6, the switch of rain shaving electrical machine 6 is a single pole double throw switch, an one gear is connected with water spray motor 5 with the ground terminal of rain shaving electrical machine 6 respectively, the ground terminal of rain shaving electrical machine 6 is connected with water spray motor 5, water spray motor 5 connects hydro-peening button switch 4, MCU2 is connected with water spray motor 5 with hydro-peening button switch 4 respectively, MCU2 control hydro-peening button switch 4 and 5 work of water spray motor; Insurance is connected wiper combined switch 1, hydro-peening button switch 4 and rain shaving electrical machine 6 respectively with combined switch 7, and hydro-peening button switch 4 connects wiper combined switch 1 and rain shaving electrical machine 6.
