Abstract:
Provided are a composite lower leg structure and a humanoid robot comprising the same. The composite lower leg structure comprises: support side plates, an embedded filler structure sandwiched between the support side plates, and a housing enclosing an outer periphery of the support side plates and the embedded filler structure. The support side plates comprise an outer lower leg side plate and an inner lower leg side plate spaced apart by a preset distance and fixedly installed at a left and right side, and the outer lower leg side plate and the inner lower leg side plate have upper ends provided with upper connection support portions used to support and connect a knee joint assembly, and have lower ends provided with lower connection support portions. The embedded filler structure comprises: an upper plug located below the upper connection support portions and fixedly connected to the support side plates; a lower plug located above the lower connection support portions; and an internal structural cavity member fixed between the upper plug and the lower plug and fixedly connected to the support side plates, the internal structural cavity member having an accommodation cavity. The structure has superior strength and rigidity in all directions, and fully utilizes the internal lower leg space.
