AI Technical Summary

Technical Problem

Existing wearable exoskeleton devices are difficult to effectively reduce the load on the human ankle joint, cannot assist walking for a long time, and may put additional load on the human body.

Method used

A mechanical structure including a joint bearing, a ball screw nut, a ball screw, and a push-pull rod mechanism was designed and installed on the back of the lower leg. It uses a servo motor to transmit torque and convert it into direct motion. The whole structure is lightweight, does not interfere with the human body, and transmits the mass to the ground, reducing additional load.

Benefits of technology

It provides effective support for the ankle joint, helping users maintain a standing gait, extend walking time, relieve ankle fatigue, and reduce the burden on the body.
