The hand driver is provided with an indicator lamp circuit, a limit sensing circuit, a permanent magnet motor and one or more work indicator lamps.
The indicator lamp circuit is provided with a first current limiting resistor R1, and one end of the first current limiting resistor R1 is respectively connected with one end of a second current limiting resistor R2 and one end of a third current limiting resistor R3; the other end of the second current limiting resistor R2 is connected with an anode of a first light emitting diode VD1; the other end of the third current limiting resistor R3 is connected with a cathode of a second light emitting diode VD2;
The limit sensing circuit is provided with the first rectifier diode D1 and a second rectifier diode D2; and

The switch is a limit switch, a microswitch or an inductive switch.
The work indicator lamp is a light emitting diode or a LED screen display or a buzzer.
The driver is a pedal driver, and the pedal driver rotates the driver to work by way of a pedal.
The electromechanical mechanism is provided with a gravity sensor for sensing creatures;

The electromechanical mechanism is also provided with an anti-pinch sensor and at least two limit magnetic sensors; and
the electromechanical mechanism is a door or a fan or a water pump or an air pump or a corresponding device driven by a motor.
Specifically, in that specific embodiment of the present utility model, a device for remotely driving and controlling the electromechanical mechanism base on a hand driver is provided; the hand driver in the device is internally provided with a permanent magnet motor and one or more work indicator lamps. When the hand driver is driven, the motor inside the driver rotates with it to generate electricity, which is connected to the driven motor unit through the power cord. After receiving the power from the power cord, the driven motor in the motor unit starts to rotate, and the electromechanical mechanism or door connected with the motor is driven by the rotation of the motor, so that the electromechanical mechanism or door moves.
In the driven electromechanical mechanism, the output shaft of the driven motor is electrically connected with an electromechanical mechanism or a door, at least two limit magnetic inductive switches are arranged on the electromechanical mechanism, and preferably, an anti-pinch sensor switch is also arranged in the electromechanical mechanism. When the motor rotates to drive the electromechanical mechanism or the door to close, if there is a creature or obstacle between the door and the anti-pinch sensor, the sensor will be powered off in real time when it is subjected to gravity, that is, the power supply between the motor and the power supply will be cut off in real time, so that the motor will stop working, thereby ensuring that creatures are not pinched when the electromechanical mechanism or door is closed; the switch can be a contact switch or a magnetic inductive switch or a corresponding inductive switch.
Preferably, the housing of the hand driver equipment is made of a metal or a hard material, and the hand driver generates electric power, is connected with the driven motor in the motor unit through the power connection line, and then electrically controls the electromechanical mechanism or door through the driven motor; An anti-pinch sensor is also arranged in the electrically controlled electromechanical mechanism or door. Further, when the hand driver rotates clockwise, the driven motor drives the electromechanical mechanism or door to open. When the hand driver rotates counterclockwise, the driven motor drives the electromechanical mechanism or door to close.
In the solution of the present utility model, the driver at least comprises a shell, a permanent magnet motor, a hand crank, an indicator lamp circuit and a limit sensing circuit. The indicator lamp circuit at least comprises a luminous indicator lamp; the light-emitting indicator lamp can be a light emitting diode, and an LED screen display can be used as a prompt, or a buzzer and other related sounding elements can be used as a prompt. The inductive switch circuit at least comprises a rectifier diode and a limit switch (a microswitch or inductive switch).
Preferably, the driven electromechanical mechanism at least includes a limit sensor (a limit switch) and an anti-pinch sensor.
Specific implementation process and principle are as below:
When the hand driver is cranked by hand, the permanent magnet motor inside the driver will run at a high speed, and the generated voltage and current will be supplied to the motor unit through the power connection line, so that the load motor in the motor unit will rotate. At this time, the indicator lamp in the hand driver will prompt (light up), indicating that the load is working; when the load is disconnected, the indicator lamp in the driver will go out, indicating that the load motor has finished working.
As shown in the figures, when the connected load is the driven motor M, when the hand driver rotates clockwise, the light emitting diode 1 (the first light emitting diode VD1) indicator lamps up. When the driven motor M meets the limit switch 2 (the second switch K2), the switch is started by contact or induction, the load is automatically turned off, and the light emitting diode 1 turns off and turns off. When the hand generator rotates counterclockwise, the indicator lamp of “light emitting diode 2” (the second light emitting diode VD2) lights up. When the driven motor M meets the “limit switch 1” (the first switch Kl), the switch is started by contact or induction, the load is automatically turned off, and “light emitting diode 2” turns off and turns off the light.
The specific suitable scene of this solution: the hand remote-driven electric push rod device suitable for doors, windows, fences, cover plates or electromechanical mechanisms driven by motors.
Installation principle of the hand driver: all accessories are fixed with screws, and there are several mounting screw holes in the hand driver, which can be fixed on the wall arm or the desktop platform with screws.
The present utility model uses a hand driver for generating and providing power in real time; and a motor unit electrically connected with the hand driver through a power cord; the motor unit electrically controls the electromechanical mechanism to work remotely in real time through the power generated by the hand driver;
That is to say, through the solution of the present utility model, combined with each functional module in the solution, the motor in the remote motor unit can be controlled to rotate only by cranking the hand driver, thus driving the electromechanical mechanism or all devices driven by the motor, such as the electromechanical structure, doors, fans, water pumps, air pumps or all devices driven by the motor; the crank of the driver can rotate the driver by hand or by foot. The electric power is generated by the remote hand driver and supplied to the motor of the driven device. The rotation of the motor drives the electromechanical mechanism or the door to move. The movable part of the driven device is equipped with a gravity sensor connected with the driven motor. When the electromechanical mechanism or the door clamps the creature, the gravity sensor will cut off the external power supply of the motor, stop the motor and stop the device from working, so as to protect the creature and allow it to have time to escape from the danger zone.
