Hiking assist exoskeleton is a lightweight battery-powered wearable lower limb exoskeleton customized for long-distance hiking, mountain trail trekking, field patrol and hilly terrain walking. Equipped with terrain adaptive real-time gait sensors and low-noise high-efficiency servo drive system, this hiking assist exoskeleton instantly identifies flat roads, uphill and downhill sections, and delivers matched graded auxiliary power to hip and knee joints to reduce lower limb bearing pressure, relieve persistent muscle soreness and mitigate knee joint wear after all-day outdoor travel. The ultra-light high-rigidity composite frame adopts IP54 dustproof, waterproof and anti-scratch outer shell, which can effectively block mud splashes, light rain and road dust to maintain stable operation under complex outdoor environments. Fully adjustable thick soft padded straps fit users of different heights and leg circumferences, paired with swappable large-capacity lithium batteries to provide long-hour continuous hiking power support. Ergonomic flexible joints do not restrict natural walking, climbing and descending movements, with simple one-touch intelligent control that hiking enthusiasts, forest rangers and field survey staff can quickly master without complex training. Built-in overload protection and automatic balance stabilization safety modules effectively prevent slipping and secondary injuries on uneven roads. This rugged hiking assist exoskeleton achieves seamless human-machine coordination, greatly reduces outdoor exercise fatigue and extends long-distance mobility endurance for users with insufficient leg strength and outdoor practitioners.
