Robotic Suit Treadmill System for Gait Training

Gait Training System Combining a Treadmill and a Wearable Lower-Limb Robotic Suit

This technology is a wearable lower-limb robot for gait training on a treadmill. It includes hip, knee, and ankle joints, and specifically features a footplate integrated with a motor and a shock absorber to assist with ankle rotation, as well as a sliding connection to the support frame to facilitate vertical movement during walking.

Conventional gait training devices often suffer from low stability due to complex, non-independent joint control and struggle to effectively prevent foot drop caused by insufficient ankle strength in patients with lower-limb paralysis.

This technology includes a footplate equipped with a motor to drive and control ankle rotation and a shock absorber (spring or gas spring) to prevent sudden movements, a multi-disk shoe link structure that allows for lateral rotation, and a hip joint connection structure that slides along the support frame to assist with vertical movement.

Key Features:

• A treadmill providing a moving surface at a set speed for the trainee, combined with a rectangular support frame extending upward.
• A hip joint link that supports waist rotation and connects to the top of the support frame, with a knee joint link extending downward.
• A footplate featuring a motor to drive and support forward/backward ankle rotation, and a shock absorber mounted at the rear to dampen these movements.
• A shoe section featuring a link connection structure where a connecting disk is inserted between two disks, allowing the base plate to rotate laterally.
