The invention provides an electro-hydraulic hybrid-driven power system for a bionic quadruped robot. The electro-hydraulic hybrid-driven power system comprises a motor pump, an integrated hydraulic cylinder and a push-rod hydraulic cylinder, wherein the output end of the integrated hydraulic cylinder is rotationally connected to the side face of the push-rod hydraulic cylinder; the motor pump is in liquid path connection with and drives the integrated hydraulic cylinder and the push-rod hydraulic cylinder, and the integrated hydraulic cylinder and the push-rod hydraulic cylinder are rotationally connected to a mounting rack of the motor pump; and the output end of the push-rod hydraulic cylinder is rotationally connected with a landing leg. The electro-hydraulic hybrid-driven power systemcombines the advantages of hydraulic drive and motor drive to meet the practical requirements of the large swing range and wide load capacity of joints to the greatest extent.
