Abstract
The problem of turning whole circle action can only be done for Wiper motor, the present invention provides a kind of control system of Wiper motor, including：Novel slip-ring, control circuit and novel automatic reset device contact, its technical scheme are：Control circuit contacts connection novel slip-ring by automatic reset contact wipe；Wherein, control circuit after power sources in series microswitch normally-closed contact by connecting electrochemical capacitor；After microswitch normally opened contact connection relay coil loop is formed with ground；Relay normally closed contact connects wherein 1 automatic reset contact；Other 2 automatic reset contacts connect microswitch normally opened contact and ground respectively.The present invention can make Wiper motor not make big change on the basis of original, and it is made rotor rotation 360/N degree, greatly extend the use range of Wiper motor.
Description
Technical field
The present invention relates to circuit for controlling motor, especially a kind of control system of Wiper motor.
Background technology
Wiper motor is a kind of our common motors in daily life, its internal slip ring such as Fig. 1 institute that automatically reset
Show, its internal rotor made for permanent magnet, contacted by 3 automatic reset contacts with slip ring, loop is formed, so as to drive
Motor.But it can only do the action for turning whole circle, the scope of application of Wiper motor is limited.
The content of the invention
The problem of turning whole circle action can only be done for Wiper motor, the present invention provides a kind of control system of Wiper motor.
A kind of control system of described Wiper motor, including：Slip ring, control circuit and automatic reset contact, its skill
Art scheme is：Control circuit contacts connection slip ring by automatic reset contact wipe；Wherein, control circuit is micro- by power sources in series
Electrochemical capacitor is connected after dynamic switch normally-closed contact；After microswitch normally opened contact connection relay coil loop is formed with ground；After
Electrical equipment normally-closed contact connects wherein a piece of automatic reset contact；Other two panels automatic reset contact connects microswitch respectively
Normally opened contact and ground.
A kind of control system of described Wiper motor, its technical scheme are：The shape of slip ring is that outside has uniform N
Individual breach, corresponding indentation, there have the projection towards the center of circle；So as to control Wiper motor to rotate 360/N degree, N is natural number.
A kind of control system of described Wiper motor, its technical scheme are：The material of slip ring is conducting metal.
The beneficial effects of the invention are as follows：The present invention can make Wiper motor not make big change on the basis of original, and
It is made rotor rotation 360/N degree, greatly extend the use range of Wiper motor.
Brief description of the drawings
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, including：Slip ring, control circuit and automatic reset
Contact, its technical scheme are：Control circuit passes through automatic reset contact a, b, c slide contact connection slip ring；Wherein, control electricity
It is grounded after connecting electrochemical capacitor C1 after routing power E series connection microswitch J normally-closed contacts J1；The J2 connections of microswitch normally opened contact
After relay K coil M loop is formed with ground；Relay k normally-closed contacts K2 connection automatic resets contact b；It is automatic multiple in addition
Position device contact a connections microswitch normally-closed contact J1 simultaneously connects with relay K normally opened contact K3, and automatic reset contact c connects
Ground connection；The coil L of relay K K1 point connecting windscreen wiper motors is simultaneously grounded.
The shape of slip ring is that outside has 2 uniform breach, and corresponding indentation, there has the projection towards the center of circle；So as to control
Wiper motor rotates 180 degree.
The course of work is：In an initial condition, power supply E's microswitch J charges for electrochemical capacitor C1；Wiper motor it is automatic
The annexation of restorer contact a, b, c and slip ring is as shown in Fig. 2 automatic reset contact a, b, the c a with slip ring respectively,、b,、
c,Corresponding, when rotor turns to the indentation, there of slip ring, now the working condition of motor is Generator Status, makes motor
Rotor is turned at equalization point, is stopped operating, and now, is met Wiper motor work 180 degree and is stopped to operation；As microswitch J
Triggering, normally-closed contact J1 are opened, and normally opened contact J2 closures, the position that Wiper motor rotor is parked in is necessarily a,Breach center line position
Put, now, b,、c,Automatic reset contact b is contacted, c is simultaneously turned on；Now, electrochemical capacitor C1 forms loop with relay coil,
Electrochemical capacitor C1 discharges, and rotor rotates by equalization point again, and electrochemical capacitor C1 discharge times are very short, after discharge off, relay
Device K coil M dead electricity, the normally opened contact J2 openings of relay K normally-closed contacts K2 closures, now microswitch J, power supply E is electricity
Electric capacity C1 chargings are solved, repeat a upper process.
Described microswitch J triggering mode, to set cam at the microswitch triggering on motor shaft.
Technical scheme as described in this description, in general permanent magnet DC motor, it is installed on motor shaft and all may be used
To use.
