  • Position limiting device and control method
    Patent number: 9467076
    Abstract: A position limiting device includes a magnetic element, a detecting element, a motor, and a controller. The magnetic element is disposed in the center of the position limiting device, the motor is coupled to the detecting element, and the controller is electrically coupled to the detecting element and the motor. The detecting element is configured to detect magnetic fields generated by the magnetic element, and correspondingly generate and transmit a magnetic field intensity signal. The controller is configured to receive and process the magnetic field intensity signal to obtain a magnetic field intensity value. In addition, the controller is further configured to compare the magnetic field intensity value and a magnetic field intensity boundary value. When the magnetic field intensity value is less than the magnetic field intensity boundary value, the controller drives the motor so that the motor makes the detecting element to move correspondingly to the magnetic element.
