Powered wearable exoskeleton is a battery-driven bionic lower limb mobility equipment integrated with real-time gait detection sensors and self-adaptive servo power system. This powered wearable exoskeleton delivers active graded power assistance to hip and knee joints, covering multi-scenario demands including elderly daily walking support, post-surgery rehabilitation training, long-distance outdoor trekking and abnormal gait correction. It can instantly judge motion modes such as standing, level walking and slope climbing, automatically output matching auxiliary torque to reduce lower limb bearing pressure, ease muscle soreness and joint fatigue caused by prolonged activity, and stabilize overall walking balance. The ultra-light high-strength composite frame reaches IP54 dustproof and waterproof standard, capable of stable operation in residential areas, gentle mountain trails and indoor rehabilitation venues. Wide soft padded adjustable straps fit users with different heights and leg circumferences, equipped with interchangeable long-lasting lithium batteries to provide all-day continuous power support. Ergonomic flexible joints will not block natural limb movement, with simple one-button control for easy operation by the elderly, rehabilitation patients and field staff. Equipped with anti-fall alert and overload automatic stop safety functions, this powered wearable exoskeleton achieves smooth human-machine coordination, significantly improving long-distance walking comfort and mobility endurance.
