The invention belongs to the technical field of vehicle parts, and particularly relates to a safety brake pedal capable of preventing sudden stepping and sudden braking, which comprises a pedal body, a sliding groove is formed in the bottom surface of the pedal body, a sliding block slides in the sliding groove, the lower end of the sliding block is rotatably connected with a connecting rod, and a shell is arranged under the pedal body. The shell is fixedly installed on the inner bottom face of a vehicle, the shell is filled with magnetorheological fluid, a horizontal lifting plate is connected into the shell in a sealed and sliding mode, the lower end of the connecting rod penetrates through the shell and is fixedly connected with the lifting plate, a plurality of flow guide holes are formed in the lifting plate at equal intervals, a threaded cylinder is rotationally connected to the upper surface of the shell, and threads are arranged on the surface of the connecting rod. According to the brake pedal, the larger the stepping force of a driver on the pedal body is, the lower the fluidity of the magnetorheological fluid is, the problems that wheels are locked and a vehicle sideslips and drifts due to the fact that the driver steps on the brake pedal suddenly are effectively avoided, and the safety performance is improved.

    本发明属于汽车配件技术领域,尤其是涉及一种防猛踩急刹的安全刹车踏板,包括踏板本体,所述踏板本体的底面设有滑槽,所述滑槽内滑动有滑块,所述滑块的下端转动连接有连接杆,所述踏板本体的正下方设有壳体,所述壳体固定安装在汽车内底面上,所述壳体内填充有磁流变液,所述壳体内密封滑动连接有水平的升降板,所述连接杆的下端贯穿壳体并与升降板固定连接,所述升降板内等距排布有多个导流孔,所述壳体的上表面转动连接有螺纹筒,所述连接杆表面设有螺纹。本发明中,驾驶员对踏板本体的踩动力度越大,磁流变液的流动性越低,有效避免了驾驶员对刹车踏板猛踩,导致车轮抱死、车辆发生侧滑飘移的问题发生,提高了安全性能。
