The brake pedal position sensor with the touch switch comprises a sensor shell, a PCB and a rotating shaft are installed in the sensor shell, the bottom of the rotating shaft extends out of the sensor shell and is connected with a rocker arm, and the rocker arm is connected with a brake pedal; the PCB close to the end part of the rotating shaft is respectively provided with a sensing chip for sensing and calculating the rotating angle of the rotating shaft and a touch switch for switching along with the rotation of the rotating shaft, and the sensing chip is arranged corresponding to the center of the rotating shaft; through cooperation of the touch switch and the sensing chip, dual detection of a touch switch signal and a position detection signal is achieved, the detection accuracy of the position sensor on the state of the brake pedal is improved, and the rocker arm drives the rotating shaft to rotate in the process of treading the brake pedal; whether the pedal is treaded in place or not is judged by turning on the touch switch through the rotating blade, and meanwhile the rotating angle of the rotating shaft is calculated through cooperation of the sensing chip and the magnetic material on the top of the rotating shaft.

    本发明公开了一种带触动开关的制动踏板位置传感器,包括传感器壳体,传感器壳体内部分别安装有PCB板和转轴,转轴底部伸出传感器壳体并与摇臂连接,摇臂与制动踏板连接;靠近转轴端部的PCB板上分别安装有对转轴转动角度进行感应计算的传感芯片以及随转轴转动实现开关的触动开关,传感芯片与转轴中心对应设置;本发明通过触动开关以及传感芯片的配合实现了接触开关信号和位置检测信号的双重检测,提高了位置传感器对制动踏板状态的检测准确性,制动踏板踩下的过程中通过摇臂带动转轴转动,并通过转动叶片打开触动开关来判断踏板是否踩踏到位,同时通过传感芯片与转轴顶部的磁性材料配合对转轴转动角度进行计算。
