The invention discloses a two-freedom-degree bionic flexible spinal structure of a quadruped robot. The two-freedom-degree bionic flexible spinal structure comprises a front drive, a flexible spine and a rear drive. The flexible spine comprises springs, a cable transmission device and a joint transmission device which is formed by overlaying a plurality of rotating mechanisms. Each rotating mechanism comprises a rotating table and a fixing frame. The cable transmission device comprises ropes and wheel discs, the rear drive is arranged on the right side of the front drive through the joint transmission device, the wheel discs are arranged in the front drive and the rear drive, and the springs are arranged between every two rotating tables. The two-freedom-degree bionic flexible spinal structure is reasonable in structure and high in universality, the flexible spinal structure capable of achieving posture adjustment and automatic turning is adopted, and the cable transmission device is adopted to control the joint transmission device to move passively so that the posture adjustment and automatic turning of the quadruped robot can be achieved at will. The two-freedom-degree bionic flexible spinal structure can be used for walking posture adjustment of the quadruped robot on the ground as well as posture adjustment and automatic turning of the quadruped robot falling off from the high altitude, and a certain buffering function is achieved.
