Vehicle door glass lifter with self-protection function
The invention relates to the technical field of vehicle doors, and discloses a vehicle door glass lifter with a self-protection function. The lifter comprises a lifting frame, a piezoresistor is fixedly connected to the inner side of the lifting frame and is close to the middle part of the lifting frame, and a negative plate is fixedly connected to the bottom of the piezoresistor and is close to the left side of the piezoresistor. According to the vehicle door glass lifter with the self-protection function, an air bin fixed to the bottom of an air pressure bin is extruded through a guide plate, air in an air bag can be discharged when the interior of the air bin is extruded, and a magnetic block can be attracted to drive a dielectric plate to move rightwards by increasing the pressure in the air pressure bin, so that the relative area of a positive plate and the negative plate is increased, the voltage of a circuit is overlarge and is larger than the maximum bearing voltage of the piezoresistor, electric power is in an open-circuit state, the motor does not rotate when not working, overload operation of the motor is avoided, damage to the motor is avoided, and the service life of the glass lifter is prolonged.
本发明涉及车门技术领域，且公开了一种具有自我保护功能的车门玻璃升降器，包括升降架，所述升降架的内侧且靠近升降架的中部固定连接有压敏电阻，所述压敏电阻的底部且靠近压敏电阻的左侧固定连接有负极板。该一种具有自我保护功能的车门玻璃升降器，通过导向板挤压固定在气压仓底部的空气仓，空气仓内部受到挤压会使得气囊内的气体放出，通过使得气压仓内的压强增大，会吸引磁块带动电介质板向右移动，使得正极板和负极板的相对面积增大，导致电路的电压过大，大于压敏电阻的最大承受电压，使得电力处于断路状态，电动机不工作也不会发生自转，避免电机发生超负荷运作，避免导致电机损坏，提高玻璃升降器的使用寿命。
