The invention relates to an electronic power-assisted brake actuator with pedal power feedback. The electronic power-assisted brake actuator is characterized by comprising an outer shell, a motor power-assisting module, a mechanical brake module and a brake feedback module. According to the invention, when a pedal is stepped down, a push rod and a magnet move forwards together, when a displacementsensor chip detects that a displacement signal is output, the motor power-assisting module pushes the displacement sensor to move forwards, the displacement sensor is also a stress piece at the sametime and transmits thrust from a screw, and then the thrust is transmitted to an ejector rod; when power power-assisted braking is conducted, the screw pushes the displacement sensor to move, and thepedal is driven to move together; when the motor power-assisting module fails, a mechanical brake module is still effective, the brake pedal is treaded by a foot, the push rod is driven, the acting force is transmitted to the displacement sensor, and then the force is transmitted to the ejector rod, so that the mechanical power-assisted-free brake is realized, the vehicle can be reliably decelerated and stopped, and the safety of the vehicle is ensured.

    本发明涉及一种带踏板电力反馈的电子助力刹车执行器,其特征在于:包括外壳体、电机助力模块、机械制动模块和制动反馈模块;本发明中当脚踏板踩下时,推杆连同磁铁一起向前运动,位移传感器芯片检测到有位移信号输出时,电机助力模块推动位移传感器向前运动,同时位移传感器本身也是受力件,传递来自螺杆的推力,进而把推力传递到顶杆;当电机助力制动时,螺杆推动位移传感器移动,制动踏板会被带着跟随一起运动,当电机助力模块发生失效时,机械制动模块依然有效,脚踩制动踏板,带动推杆,作用力到位移传感器,再传力到顶杆,从而实现机械无助力的制动,可以保证车辆可靠地实现减速和停止,保证车辆安全。
