Problems solved by technology

[0003] In addition, most of the current anti-pinch devices are based on some sensors, such as infrared, ultrasonic, and laser sensors, to achieve automatic anti-pinch functions, but because the sensors are expensive, the cost will be relatively high, and they cannot be popularized.

Embodiment Construction

[0060] Please refer to figure 1 , is the frame diagram of the anti-pinch window system of the present invention. Such as figure 1 As shown, the anti-pinch window system includes a microcontroller 110 , a relay unit 120 , a lifting motor 130 , and a window glass 140 . Wherein, the lift motor 130 has an encoder 135 , and the encoder 135 includes a front contact A and a rear contact B, so as to generate a front contact signal Pa and a rear contact signal Pb to the microcontroller 110 . In this embodiment, both the front contact signal Pa and the rear contact signal Pb are square wave signals, and the phase difference between the front contact signal Pa and the rear contact signal Pb is 90 degrees, so that the microcontroller 110 can judge the current rise and fall The motor is forward or reverse.

[0061] Please also refer to figure 2 , the window glass 140 is connected to the lifting motor 130 , and the window glass 140 is located in a movable zone Zone, so that the vehicle...

Abstract

The invention relates to an anti-pinch car window system which comprises an encoder and an elevator motor, car window glass positioned in a movable area, a signal in line with a position, microcontroller controlling the elevator motor through pulse wave sampling times and a relay unit supplying power to the elevator motor to enable the elevator motor to turn forward or reversely. Therefore the position of the car window glass in the movable area is in an anti-pinch area, and when the microcontroller judges that an object is placed on the car window glass, the microcontroller controls the elevator motor to turn reversely, and the car window glass is prevented from clamping the object.

Description

technical field [0001] The invention relates to a vehicle window system, in particular to an anti-pinch vehicle window system. Background technique [0002] Most of today's vehicles use electric windows, and the up and down movement of the lift motor is controlled by pressing the lift switch, thereby driving the movement of the window glass. However, under the condition of conveniently controlling the car window, if there is an object on the car window and the car window is continuously controlled to move up, it is easy to cause the movable range of the car window to become smaller and smaller due to the user's inattention. Clip to this object. If again when this object is a child's head or hand, it will cause irreparable danger even more. Therefore, power windows need anti-pinch devices to avoid danger. [0003] In addition, most of the current anti-pinch devices rely on some sensors, such as infrared, ultrasonic, and laser sensors, to achieve automatic anti-pinch functi...
