Car window glass lifting anti-pinching device
The invention discloses a car window glass lifting anti-pinching device. The car window glass lifting anti-pinching device is characterized in that a hall sensor arranged on a car window motor acquires a rotating speed signal of the motor and then sends the rotating speed signal to a processor MCU so that the real-time rotating speed of the motor can be calculated; besides, resistance exerted on a glass lifter is judged according the changing speed and changing rate of the rotating speed; finally, whether a barrier exists on a car window or not is judged, and the motor is driven to rotate reversely to prevent pinching. By the adoption of the structural method, whether the barrier exists in the operating direction of the car window is automatically detected, and when the car window runs into the barrier and certain force is reached, car window glass rotates reversely to prevent a person from being injured. The car window glass lifting anti-pinching device is low in hardware cost and suitable for being applied and popularized in various types of cars.
