The scraping arm of Windshield Wiper off-premises station rests on the window-glass may block driver vision sometimes, does not have concrete regulation and requirement in the naval vessel Windshield Wiper universal standard, but in actual use preferably the scraping arm of Windshield Wiper rest on the both sides of window-glass.At present, mostly adopt a master cock to control scraping arm and automatically reset, this switch is installed on the panel of controller of Windshield Wiper, behind the Windshield Wiper withdraw from use, as when finding that scraping arm rests on the position of blocking sight line, press this switch and make scraping arm near glass avris place cut-off switch; This scraping arm reset mode exists the speed control of scraping arm bad in actual mechanical process, make scraping arm not rest on the position that need park easily, the bad grasp in stop place simultaneously causes not in place easily or has crossed the situation of stop place, therefore, the existing scraping arm in fact hand reset that resets.
Summary of the invention
The purpose of this utility model is at existing ship to provide a kind of reliability and stability high Windshield Wiper scraping arm self-resetting circuit with the problem that parallel-moving type Windshield Wiper scraping arm resets.
The technical solution of the utility model is as follows: a kind of Windshield Wiper scraping arm self-resetting circuit, comprise by source switch and power supply bonded assembly power source conversion interface circuit, the power source conversion interface circuit is connected with the power source conversion control circuit, the power source conversion control circuit connects the Windshield Wiper supply convertor, and the Windshield Wiper supply convertor is connected with the drive motor armature of Windshield Wiper by the output translation interface; The power source conversion interface circuit also is connected with position detecting circuit, and position detecting circuit is connected with position-detection sensor, and the mouth of position detecting circuit connects the power source conversion control circuit.
Windshield Wiper scraping arm reset circuit of the present utility model has realized that real scraping arm automatically resets, it does not need manual operation, the stop motion position is arrived at same position in the position of scraping arm setting in motion, no matter the scraping arm running velocity of former Windshield Wiper is fast or slow, after closing the Windshield Wiper run switch, it always gets back to the initial position with a constant speed, and the two positions error is no more than ± 10mm; After scraping arm automatically resets, cut off the power supply of changer automatically, carry out energy-conservationly, be in readiness for action, the power consumption during standby realizes environmental protection below 1w.
Description of drawings
Fig. 1 is the utility model Windshield Wiper scraping arm self-resetting circuit functional block diagram.
Fig. 2 is the physical circuit figure of Windshield Wiper scraping arm self-resetting circuit.
The specific embodiment
As shown in Figure 1 and Figure 2, Windshield Wiper scraping arm self-resetting circuit comprises by source switch and power supply bonded assembly power source conversion interface circuit, the power source conversion interface circuit is connected with the power source conversion control circuit, the power source conversion control circuit connects the Windshield Wiper supply convertor, and the Windshield Wiper supply convertor is connected with the drive motor armature of Windshield Wiper by the output translation interface; The power source conversion interface circuit also is connected with position detecting circuit, and position detecting circuit is connected with position-detection sensor, and the mouth of position detecting circuit connects the power source conversion control circuit.
This circuit is the circuit of development and Design on the basis of Windshield Wiper changer, make full use of the power supply input of changer and the principle that speed can be set, because of circuit can have to a certain degree impact to changer in switching process, be provided with a certain amount of buffering compensation at the changer internal circuit, reduce the impact that produces because of reset circuit work.
The scraping arm of Windshield Wiper is opened run switch when start bit, governing speed knob scraping arm can progressively quicken to leave start bit, the source switch of scraping arm reset circuit is sent power supply and is given the power source conversion interface circuit, sending Windshield Wiper needs operating instruction to give the power source conversion control circuit, give the power supply of Windshield Wiper supply convertor simultaneously, the drive motor armature of Windshield Wiper gets electric work and brings into operation, and position-detection sensor and testing circuit are not worked.
Close the run switch of Windshield Wiper, the power source conversion interface circuit obtains stopping the order of Windshield Wiper, danger signal is given the power source conversion control circuit, the power source conversion interface circuit is powered to position detecting circuit simultaneously, if movable body is not when the initial position that stops, position detecting circuit ejecting motion body is not given the power source conversion control circuit at the signal of position, the power source conversion control circuit continues power supply for the Windshield Wiper supply convertor, allow drive motor obtain a constant driving voltage, scraping arm runs to start bit with constant speed, sensor is sent at position signal and is given the power source conversion control circuit then, stop to power to the Windshield Wiper changer, scraping arm stops at start bit, reaches the purpose that scraping arm resets.
In conjunction with shown in Figure 2, its concrete working process is as follows:
When run switch is in the operation position, the terminal 1 and 0 of Terminal 1 among Fig. 2, terminal 4 communicates separately with 3, power module (POWER CONTROLLER) invocation point work, regulate the big I of R1 and make Windshield Wiper drive motor (WIPER MOTOR) obtain different armature voltages, Windshield Wiper is scraped with friction speed and is swept rainwater on glass.
When run switch places stop bit, the terminal 1 and 2 of Terminal 1 among Fig. 2, terminal 4 communicates with 5.
Movable body is not in sensor (SENSOR) detection range, and sensor detection circuit is sent to close with the loop, contact and given the power source conversion control circuit; When movable body in detection range, sensor detection circuit provides the loop for the power source conversion control circuit.
When movable body not in the sensor scope, KM1, KM2 get electric, make power module get electric work, the speed setting of power module is simultaneously controlled by R0, the total timing that dispatches from the factory that is arranged on of R0 presets, movable body is with constant-speed operation.
When sensor to movable body, examined circuit control, KM1, KM2 dead electricity, the input of power module non-transformer, motor is out of service because of no armature voltage, scraping arm is got back to reference position, this circuit plays the scraping arm reset effect.
