Wheelchair-type gait assistance robot

Wheelchair-type gait assistance robot combining a linear guide lift and an exoskeleton

This technology is a wheelchair-type gait assistance robot that integrates a lift composed of outer and inner linear guides into a drive unit equipped with drive motors and wheels, featuring a seat upper connected to the inner linear guide and an exoskeleton worn on the user's lower body.

Existing gait assistance devices have suffered from issues such as a lack of structural stability, limited operational space, and reduced effectiveness during long-distance travel, all of which increase the burden on the user.

This technology proposes a method for stably elevating the seat upper using a linear actuator and dual linear guides, while integrating it with an exoskeleton. Applicable to lower-limb rehabilitation and long-distance mobility assistance, it allows for seamless switching between gait training and wheelchair use in a single device, ensuring both structural stability and versatility.

Key Features:

• A drive unit comprising a main frame, drive motors installed on the main frame, and wheels driven by the drive motors
• An outer linear guide fixed to the main frame and an inner linear guide capable of vertical movement along the outer guide
• A seat upper connected to the inner linear guide and configured to move vertically with it
• A linkage assembly connected to the outer linear guide that unfolds and folds in response to the elevation of the inner linear guide
