Powered walking suit is a battery-driven wearable lower limb exoskeleton with integrated intelligent gait sensing and adaptive power output, designed for daily walking, slope climbing, long-distance outdoor trekking and lower limb rehabilitation training. This powered walking suit accurately captures human standing, walking and uphill motion signals in real time, and delivers graded auxiliary torque to hip and knee joints to evenly reduce lower limb bearing load, effectively easing joint soreness, muscle stiffness and fatigue caused by prolonged movement. Constructed with ultra-light high-strength composite frame, the whole unit reaches IP54 dustproof and waterproof standard, supporting stable use in residential roads, gentle mountain trails and indoor rehabilitation spaces. Multi-layer soft padded binding belts support full-range size adjustment to match users of different heights and leg circumferences, equipped with replaceable long-lasting lithium batteries to provide all-day continuous walking assistance. Flexible ergonomic joint structure will not restrict natural limb movement, equipped with one-button simple control for easy operation by the elderly, postoperative rehabilitation patients and field workers. With smooth human-machine synchronization, this powered walking suit greatly improves walking balance, long-distance mobility comfort and outdoor activity endurance.
