Description
Affiliated technical field
The present invention relates to the motor switch device, particularly the self-act travel switch of direct current machine and the automatic pass stop device behind the stall.
Background technology
Before the applying date, the work of motor is through manually controlling the opening and closing power supply, when the motor rotation, when being hampered stall, like untimely powered-down, just can burn out motor.
Know that again need all to close automatically vehicle window, additional window shutter to adopt the Car window electric machine delay working to close vehicle window behind the automotive lock car, this mode mistake easily crushes children, and all types of vehicle window height is different, time-delay is different, possesses very strong unicity.The time-delay overlength just can make the Car window electric machine stall that is hampered.
In order to solve the problem of motor rotation blockage, present new technology is: little value resistance of series connection in motor circuit, and the resistance two ends connect the single-chip microcomputer current sampling circuit; When in the machine operation process, running into obstacle, motor rotation blockage, resistance one end electric current increases, through changing into voltage amplification through command switch disable motor power supply after the single-chip microcomputer computing after the single-chip microcomputer sampling.But this mode cost is higher, do not suit in low and middle-grade automobiles, to apply, and the more complicated easy break-down of circuit.
Summary of the invention
It is humble that the object of the invention designs a kind of cost exactly, not fragile, can protect motor automatically, the identification motor rotation blockage, can work while or a kind of motor switch of Close All vehicle window automatically in turn behind the lock car immediately.
The present invention realizes through following scheme: a kind of motor switch of automatic identification; Comprise the relay that motor power is provided; It is characterized in that: the resettable fuse thermistor electrical connection that relay self control end that adopting provides motor power is connected with the relay common port, measure the stall of motor, the big resistance that behind motor rotation blockage, produces according to the resettable fuse thermistor; The work of slew relay control end, the disable motor working power.
Resettable fuse thermistor of relay common port series connection is electrically connected with the positive electrical input of motor, and relay control end positive electrical connects positive electrical input one end of motor of resettable fuse thermistor.
Relay control end negative electricity connects motor negative electricity input.
Output provided when relay control end coil current was worked by relay, the anodal electric connection of power supply trigger switch of relay control end one end, and the relay initialization, the control end coil current is triggered by mains switch and provides.
Described resettable fuse thermistor is PTC from resetting the fuse thermistor, in the time of also can being the big electric current of any generation, can producing big resistance or break off the temperature detect switch (TDS) that connects.
Relay normally open end electric connection of power supply cathode output end, relay normal-closed end electric connection of power supply cathode output end.
Such design is for after relay control end positive pole is by the positive supply switch triggering, relay work, and common port has electricity, and the positive electrical input of motor has electricity, continues to provide relay control end electric current, relay work, machine operation.Behind motor rotation blockage, the positive electrical input of motor produces big electric current, and resettable fuse thermistor resistance sharply increases, and the relay control end is unable keeps relay work, cut-off, and motor quits work.
When the present invention when the motor vehicle windows motor uses, need whole vehicle windows to close window behind the lock car, rises the window motor and all works simultaneously, electric current is understood excessive; For battery feed is reduced the heavy burdens, it is taken turns to operate automatically, needing increases an electric capacity in the motor switch circuit of second and subsequently a kind of automatic identification, be used as the power supply trigger switch; Relay control end positive pole to motor power triggers, and the motor power relay is worked automatically, and its circuit is following:
The relay control end positive pole of motor power connects the positive pole of an electric capacity again through diode electrically; The negative pole of electric capacity connects negative supply, and the positive pole of electric capacity connects the motor power relay common port that is electrically connected the motor switch of previous automatic identification behind the relay control end negative pole of motor power again through diode electrically again.
Anodal motor power input one end that increases diode electrically connection resettable fuse thermistor of motor power relay control end.
Such design is for when whole motors need take turns to operate, after the proper utmost point of the motor switch circuit relay electrical equipment control of first a kind of automatic identification is by the positive supply switch triggering; Relay work; Common port has electricity, and the positive electrical input of motor has electricity, and relay control end positive pole has; Relay work is provided, machine operation.Behind motor rotation blockage, the positive electrical input electric current of motor sharply increases, and resettable fuse thermistor resistance increases the unable relay work of keeping, cut-off, and motor quits work.
When the motor switch circuit relay electrical equipment common port of first a kind of automatic identification has electricity, because the capacitance cathode in the motor switch circuit of second a kind of automatic identification is electrically connected the electric capacity charging with it through diode.
After the motor switch circuit relay electrical equipment of first a kind of automatic identification cuts out; The normal-closed end return; Common port connects negative supply, because the motor switch circuit relay electrical equipment control end negative pole of second a kind of automatic identification is electrically connected with the motor switch circuit relay electrical equipment common port of first a kind of automatic identification; So behind the capacitor discharge, the trigger relay control end is worked in the motor switch circuit of second a kind of automatic identification.So circulation is finished the work to the motor switch of last a kind of automatic identification in turn.
Just know that through above design the present invention is that to have a cost humble really, be hampered and promptly stop that reaction can be discerned motor rotation blockage, the motor switch of a kind of automatic identification that can take turns to operate fast automatically.
