Thigh mechanism of simulation robot

Abstract

A simulation robot thigh mechanism comprises a leg crossing driving assembly, a thigh assembly and a knee joint driving motor. The leg-spanning driving assembly comprises a leg-spanning driving motor; the thigh assembly comprises a striding and swinging output structural member, a striding and swinging driven end structural member, a leg rotation driving motor and a leg extending member; the power output end of the striding leg driving motor is connected with a striding swing output structural member, and the other end of the striding leg driving motor is connected with a striding swing driven end structural member; a leg rotation power output structural member is arranged between the straddle swing output structural member and the straddle swing driven end structural member, and the power output end of the leg rotation driving motor is connected with the leg rotation power output structural member; the lower end of the leg rotation driving motor is connected with a leg extension piece; knee joint driving motors are connected to the lower ends of the leg extending pieces. The thigh structure is high in overall layout compactness and high in joint integration degree, a large motion range of a robot can be achieved, and flexibility and universality are improved.
