Gait assistance exoskeleton is an intelligent wearable lower limb power assist device built for standardized gait correction, walking support and multi-scenario mobility training. Integrated with high-precision real-time gait tracking sensors, adaptive servo drive modules and intelligent gait algorithm, this gait assistance exoskeleton can capture users’ walking posture in real time, output graded targeted auxiliary torque to hip and knee joints, correct abnormal walking postures, evenly disperse lower limb load and ease joint stiffness, muscle soreness and fatigue caused by long-time walking or rehabilitation training. The ultra-light high-strength composite frame reaches IP54 dustproof and waterproof grade, suitable for hospital rehabilitation rooms, home daily training, community walking and light outdoor hiking. Fully adjustable wide soft padded binding belts fit users of different heights and leg circumferences, matched with swappable long-lasting lithium batteries to support all-day continuous gait assistance. Flexible ergonomic joint structure will not restrict natural limb movement, with simple one-button control for easy operation by the elderly, postoperative rehabilitation patients and mobility-impaired groups. This professional gait assistance exoskeleton realizes smooth human-machine synchronization, effectively stabilizes walking balance, optimizes gait posture and greatly improves long-distance walking comfort and mobility endurance.
