Abstract
The problem turning whole circle action can only be done for Wiper motor, the utility model provides a kind of control system of Wiper motor, comprise: slip ring, control circuit and automatic reset contact, its technical scheme is: control circuit is by automatic reset contact wipe contact connection slip ring; Wherein, control circuit connects electrochemical capacitor by after power sources in series sensitive switch normally-closed contact; With formation loop, ground after sensitive switch normally opened contact connection relay coil; Relay normally-closed contact connects wherein a slice automatic reset contact; Two panels automatic reset contact connects sensitive switch normally opened contact and ground respectively in addition.The utility model can make Wiper motor not make large change on original basis, and makes it make rotor rotation 360/N degree, extends the scope of application of Wiper motor greatly.
Description
Technical field
The utility model relates to circuit for controlling motor, especially a kind of control system of Wiper motor.
Background technology
Wiper motor is our a kind of motor common in daily life, its inside automatically reset slip ring as shown in Figure 1, its inner rotor made for permanent magnet, is contacted with slip ring by 3 automatic reset contacts, formation loop, thus drive motors.But it can only do the action turning whole circle, limits the scope of application of Wiper motor.
Summary of the invention
Can only do the problem turning whole circle action for Wiper motor, the utility model provides a kind of control system of Wiper motor.
The control system of described a kind of Wiper motor, comprising: slip ring, control circuit and automatic reset contact, and its technical scheme is: control circuit is by automatic reset contact wipe contact connection slip ring; Wherein, control circuit connects electrochemical capacitor by after power sources in series sensitive switch normally-closed contact; With formation loop, ground after sensitive switch normally opened contact connection relay coil; Relay normally-closed contact connects one of them automatic reset contact; Two other automatic reset contact connects sensitive switch normally opened contact and ground respectively.
The control system of described a kind of Wiper motor, its technical scheme is: the shape of slip ring is that outside has uniform N number of breach, and corresponding indentation, there has the projection towards the center of circle; Thus controlling Wiper motor rotation 360/N degree, N is natural number.
The control system of described a kind of Wiper motor, its technical scheme is: the material of slip ring is conducting metal.
The beneficial effects of the utility model are: the utility model can make Wiper motor not make large change on original basis, and make it make rotor rotation 360/N degree, extend the scope of application of Wiper motor greatly.
Accompanying drawing explanation
Fig. 1 is traditional slip ring that automatically resets; Fig. 2 is slip ring schematic diagram; Fig. 3 is control circuit schematic diagram.
Embodiment
According to Fig. 2 ~ 3, a kind of control system of Wiper motor, comprising: slip ring, control circuit and automatic reset contact, and its technical scheme is: control circuit passes through automatic reset contact a, b, c sliding contact connection slip ring; Wherein, control circuit is connected by power supply E and to be connected ground connection after electrochemical capacitor C1 after sensitive switch J normally-closed contact J1; With formation loop, ground after the coil M of sensitive switch normally opened contact J2 connection relay K; Relay k normally-closed contact K2 connects automatic reset contact b; Automatic reset contact a connects sensitive switch normally opened contact J2 and connects with the normally opened contact K3 of relay K in addition, and automatic reset contact c connects ground; The coil L of the K1 point connecting windscreen wiper motor of relay K ground connection.
The shape of slip ring is that outside has 2 uniform breach, and corresponding indentation, there has the projection towards the center of circle; Thus control Wiper motor revolves turnback.
The course of work is: in an initial condition, power supply E is that electrochemical capacitor C1 charges to sensitive switch J; The automatic reset contact a of Wiper motor, the annexation of b, c and slip ring as shown in Figure 2, automatic reset contact a, b, c respectively with a of slip ring
,, b
,, c
,corresponding, when rotor turns to the indentation, there of slip ring, now motor operating state be Generator Status, make rotor turn to balance point place, stop operating, now, meet Wiper motor work 180 degree and stop to operation; When sensitive switch J triggers, normally-closed contact J1 opens, and normally opened contact J2 closes, and the position that Wiper motor rotor is parked in must be a
,breach midline position, now, b
,, c
,contact automatic reset contact b, c and conducting; Now, electrochemical capacitor C1 and Wiper motor rotor coil form loop, electrochemical capacitor C1 discharges, and rotor is rotated through balance point again, and electrochemical capacitor C1 is very short for discharge time, after discharge off, the coil M dead electricity of relay K, relay K normally-closed contact K2 closes, and now the normally opened contact J2 of sensitive switch J opens, power supply E is that electrochemical capacitor C1 charges, and repeats a process.
The triggering mode of described sensitive switch J, for sensitive switch triggering place on motor shaft arranges cam.
Technical scheme as described in this description, for general permanent magnet DC motor, is installed on motor shaft and can uses.
