The invention discloses a brake pedal arm active disengaging structure which comprises a pedal arm, a pedal seat, a main cylinder, a rotating mechanism, a supporting mechanism and an actuating mechanism, the pedal seat is installed on the main cylinder, the main cylinder is connected with the pedal arm, the pedal arm is rotatably connected with the pedal seat, and the rotating mechanism, the supporting mechanism and the actuating mechanism are all installed on the pedal seat. The rotating mechanism can rotate relative to the pedal seat, the rotating mechanism and the supporting mechanism are fixed, the supporting mechanism abuts against the actuating mechanism, an opening is formed in the pedal seat, the pedal arm is limited in the opening through the supporting mechanism, and when a vehicle collides, the actuating mechanism is started and separated from the supporting mechanism, and the supporting mechanism loses abutting force and rotates around the rotating mechanism. And in the rotating process, the pedal arm is separated from the opening. According to the invention, the connection between the pedal arm and the pedal seat can be actively disconnected when a vehicle is heavily collided, so that the pedal arm can be thoroughly prevented from invading and hurting the feet or legs of a driver.

    本发明公开了一种制动踏板臂主动脱落结构,包括踏板臂、踏板座、主缸、转动机构、支撑机构、作动机构,踏板座安装在主缸上,主缸与踏板臂连接,踏板臂与踏板座可转动连接,转动机构、支撑机构、作动机构均安装在踏板座上,且转动机构可相对踏板座转动,转动机构和支撑机构固定,支撑机构和作动机构抵接,踏板座上设有开口,踏板臂通过支撑机构限位在开口内,当车辆发生碰撞时,作动机构被启动,并与支撑机构分离,支撑机构失去抵接力绕转动机构转动,转动过程中,踏板臂从开口中脱离。本发明可在车辆发生较重的碰撞时主动断开踏板臂与踏板座的连接,能够彻底避免踏板臂侵入伤害驾驶员脚部或腿部。
