The invention provides an electro-hydraulic hybrid leg of a quadruped robot, and relates to the technical field of quadruped robots. The device comprises a main shaft, a mounting piece, a first servo micro hydraulic module, a thigh, a hip joint, a first motor module, a second motor module, a third motor module, a transmission mechanism, a shank shaft, a shank, a second servo micro hydraulic module and a flexible foot end module. The hip joint is driven to rotate through the first motor module, and the trunk containing space is increased. A motor module and a servo micro hydraulic module form a hybrid drive hip pitching joint and a knee pitching joint, an electro-hydraulic hybrid power technology is utilized, the output torque ratio of a motor and a hydraulic cylinder is optimized, the power performance of the hip pitching joint and the knee joint is improved, and the energy consumption of a machine body is reduced. The electro-hydraulic hybrid leg foot has sufficient power, strong explosive power, high power density ratio, excellent dynamic response capability and good special environment adaptability, and is a premise and guarantee for the quadruped robot to complete various complex actions.
