AI Technical Summary

Technical Problem

The structure of the ankle articulated shaft of existing robots is complex, the structural strength is low and difficult to process, resulting in high processing costs.

Method used

An ankle articulation shaft including a first connecting rod section, a first connecting rod section, a shoulder section, a second connecting rod section and a second connecting rod section is designed. By providing a generally annular shoulder at the shoulder section, the structural strength is enhanced, and the processing process is simplified through an integrated molding structure and a reduced material processing method.

Benefits of technology

The compact structural design of the ankle articulated shaft is realized, which improves structural strength, simplifies the processing process and reduces production costs.

Abstract

The invention relates to the technical field of robots, and discloses an ankle hinge shaft, an ankle hinge structure and a shank structure of a robot and a humanoid robot. Wherein the ankle hinge shaft comprises a first connecting rod section, a first connecting shaft section, a shaft shoulder section, a second connecting shaft section and a second connecting rod section which are connected in sequence, the first connecting shaft section, the shaft shoulder section and the second connecting shaft section are concentrated in the middle and can be used for installing the ankle hinge shaft, the structural shape of the ankle hinge shaft has high strength, and due to the arrangement of a clamping shoulder, the ankle hinge shaft can be installed conveniently. The connecting strength of the first connecting shaft section, the shaft shoulder section, the second connecting shaft section and the shaft shoulder section is improved, and the structural strength of the connecting shaft is further improved. The first rocker hinge section and the second rocker hinge section are far away from the middle part, and the two ends of the shaft body are not required to be further assembled except for hinge points, so that the length of the shaft body is reduced, materials are saved, the processing is more convenient, and the production cost can be effectively reduced.
