Mobility support exoskeleton is a lightweight wearable bionic power assist system designed to provide stable lower limb support for daily walking, slope climbing, outdoor trekking and rehabilitation recovery. Equipped with multi-point real-time motion sensors and self-adaptive servo power modules, this mobility support exoskeleton intelligently identifies standing, flat walking and uphill states, and delivers moderate auxiliary torque to hip and knee joints to reduce lower limb bearing pressure, relieve muscle fatigue and joint soreness after long-term movement, and improve overall walking stability. The whole frame adopts ultra-light high-toughness composite material with IP54 dustproof and waterproof performance, which can operate stably in home passages, community roads and gentle mountain trails. Widened soft padded binding straps support full-size adjustment to fit users of various heights and leg lengths, equipped with interchangeable long-life lithium batteries to realize all-day continuous mobility assistance. Flexible ergonomic joints allow unobstructed natural limb movement, matched with simple one-key control for easy operation. Widely applicable to seniors with weak legs, postoperative rehabilitation patients, field workers and outdoor walkers, this mobility support exoskeleton achieves smooth human-machine coordination, effectively enhances long-distance walking comfort and extends outdoor activity endurance.
