Abstract
A method for controlling a windscreen wiper to return accurately is characterized in that a vehicle controller, a worm wheel metal slip sheet (1) and an elastic contact are arranged, an intermediate relay (2) is connected between a white line and a blue line of a motor in series, and the worm wheel metal slip sheet (1) is annular and is provided with a notch; when the worm wheel metal slip sheet is located at the position of the notch and stopping is needed, the intermediate relay is disconnected, a chopping signal is transmitted through an auxiliary contact of the intermediate relay to a PLC or single-chip microcomputer or the like for control, automatic power off is conducted after power supply to the motor is continued for 0.5-1.2 s, and at the moment, automatic stopping is achieved after the motor runs for another time. By the adoption of the method, the wiper motor is accurately controlled to stop, and the quality of windscreen wiper products is improved.
Description
Technical field
The present invention relates to vehicle wiper, particularly a kind of method controlling the accurate return of windscreen wiper.
Background technology
The rain shaving electrical machine of mechanical type return principle, because windscreen wiper parking return is interval large, causes wiper arm return bad.
Analyze rain shaving electrical machine parking principle, see Fig. 1 and following table
Motor picks out three lines, black line, blue line and white line.During normal work, power supply returns black line through white line to motor, when realizing motor parking return, cut off black line, power supply returns blue line through metal slide plate again through white line and forms loop, motor works on, when running to Fig. 1 metal slide plate indentation, there, because indentation, there forms open circuit, motor is parked in position as shown in Figure 1 by after a bit of for operation distance due to inertia, i.e. ideal position, this position is in the midway location of metal slide plate breach.
But there is a kind of situation that motor return will be caused inaccurate, exactly when motor return will be realized, motor has run to metal slide plate gap position place, this time, motor will due to inertia run a segment distance after stop, be usually in the second half section position of slide plate breach, as shown in Figure 2, differ greatly with orderly shutdown position, usually see that wiper falls down, this is one of reason.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of precision control method controlling the accurate return of windscreen wiper is provided, ensure dispatch from the factory product stop conformability.
The present invention solves technical problem underlying and realizes by the following technical solutions: a kind of method controlling the accurate return of windscreen wiper, comprise car body controller, worm gear metal slide plate 1 and elastic contact, at motor white line and an intermediate relay 2 of connecting between blue line, worm gear metal slide plate 1 is annular, and be with jagged, when motor slide plate is in gap position and needs to stop, intermediate relay forms open circuit, break signal passes through the auxiliary contact signal transmission of intermediate relay to the control such as PLC or micro controller system, continue to after feeding electric motors 0.5-1.2 second, auto-breaking again, now motor once realizes automatic train stop through rerunning.
Continue to the feeding electric motors time because of after scrape motor speed about 35 revs/min, turning around about 1.7 seconds, in order to ensure that motor can turn over slide plate gap position, therefore being set to 0.5-0.8 second.
PLC controls, and: M30.0 represents and starts shut off cock, and I0.1 represents whether be on stop position, if be on stop position, starts M31.0, and restart shut off cock after continuing power supply 0.5-0.8 second to motor, ideal position is got back in motor operation.
The present invention compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the present invention accurately controls rain shaving electrical machine and stops, and improves windscreen wiper product design.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to a kind of method detailed description of the invention, structure, feature and the effect thereof controlling the accurate return of windscreen wiper proposed according to the present invention, be described in detail as follows.
See Fig. 3-5, a kind of method controlling the accurate return of windscreen wiper, comprise car body controller, worm gear metal slide plate 1 and elastic contact, at motor white line and an intermediate relay 2 of connecting between blue line, worm gear metal slide plate 1 is annular, and be with jagged, when motor metal slide plate is in gap position and needs to stop, intermediate relay forms open circuit, break signal passes through the auxiliary contact signal transmission of intermediate relay to the control such as PLC or micro controller system, continue to after feeding electric motors 0.5-1.2 second, auto-breaking again, now motor once realizes automatic train stop through rerunning.
Continue to the feeding electric motors time because of after scrape motor speed about 35 revs/min, turning around about 1.7 seconds, in order to ensure that motor can turn over slide plate gap position, therefore being set to 0.5-1.2 second.
PLC controls, and: M30.0 represents and starts shut off cock, and I0.1 represents whether be on stop position, if be on stop position, starts M31.0, and restart shut off cock after continuing power supply 0.5-1.2 second to motor, ideal position is got back in motor operation.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
