Waist assisting exoskeleton

The utility model discloses a waist power-assisted exoskeleton, and relates to the technical scheme of wearable exoskeletons.The waist power-assisted exoskeleton comprises a back frame body, the back frame body comprises an elastic plate, the elastic plate can deform along with the trunk movement of a wearer in the wearing state, and the waist power-assisted exoskeleton further comprises leg wearing parts and elastic energy storage parts; the leg wearing parts can be worn on the legs of the human body, the leg wearing parts are connected with the back frame body through the elastic energy storage parts, when a wearer bends down, the elastic plate parts and/or the elastic energy storage parts deform to store energy so as to provide restoring force for pulling the trunk of the human body to move backwards in the upright direction, and therefore the effect of providing greater assistance for the wearer is achieved; the operation of the wearer is facilitated, the load capacity of the wearer is improved, and the i
