The invention relates to an automatic wiping device for a rolling stock. The automatic wiping device comprises a humidity sensor and a wiping device, the scraping and brushing module is used for scraping and brushing rainwater on the glass surface of the vehicle window; the torque sensor is used for collecting return stroke torque output when the scraping brush module rotates; the motor is used for driving the scraping and brushing module to rotate; the controller is used for receiving a signal which is transmitted by the humidity sensor and is used for detecting rainwater, controlling the motor to rotate to drive the wiping module to wipe the rainwater on the glass surface of the car window, outputting return torque which is transmitted by the torque sensor when the wiping module rotates, adjusting the wiping interval time along with the change of the return torque, and controlling the wiping module to wipe the rainwater on the glass surface of the car window. After the interval time is reduced to zero, if the torque continues to be reduced, the rotating speed of the motor I is increased, if the torque remains unchanged or is increased, the rotating speed of the motor I remains unchanged, and the device achieves real-time change of the scraping frequency according to rainfall; automatic adjustment of the pressure of the wiper and the glass is achieved, and the wiping effect is improved.
本发明一种机车车辆用自动刮刷装置,包括:用于检测是否下雨的湿度传感器;用于对车窗的玻璃表面的雨水进行刮刷的刮刷模块;用于采集刮刷模块转动时输出的回程转矩的扭矩传感器;用于驱动刮刷模块进行转动的马达;接收湿度传感器传送的检测到有雨水的信号的控制器,控制器控制马达转动带动刮刷模块对车窗的玻璃表面的雨水进行刮刷,控制器再根据扭矩传感器传送的所述刮刷模块转动时输出回程转矩,随回程转矩变化先调整刮刷间隔时间,间隔时间减小至零后,若转矩继续减小此时增大马达I的转速,若转矩保持不变或增大,则马达I的转速保持不变,该装置实现刮刷频率根据雨量实时变化;解决刮刷器与玻璃压力的自动调整,提高刮刷效果。
