Abstract

The invention discloses a pseudo passive power assisting device for ankle joint movement, and relates to the power assisting device for ankle joint movement. The invention aims to solve the problem that the existing power assisting device is easy to interfere and short in continuous work time and wastes energy sources. According to the power assisting device provided by the invention, the front sole and the rear sole is rotatably connected, the sole is fixedly installed on the rear part of the bottom end face of the rear sole, and one end of the abduction or adducted joint is rotatably connected to the upper end of the rear sole and an energy storage mechanism is arranged at the upper end at the other end of the abduction or adducted joint. The lower end of the energy storage mechanism and the other end of the abduction or adducted joint are connected trough a movement steel wire rope. The upper end of the energy storage mechanism is sequentially provided with a clutch, a reducer and a driving motor. An outer circular frame is fixedly installed on an outer ring, and an inner circular frame is arranged in the outer circular frame. Guide rails are respectively arranged on the upper and lower parts of the inner circular frame. A medial rotation or lateral rotation fixing sleeve is arranged at the upper end of the inner circular frame, and a plurality of chutes matched with the guide rails are respectively arranged on the inner wall of the outer circular frame. The pseudo passive power assisting device for ankle joint movement provided by the invention is suitable for power assist of the ankle joint.

Description

technical field [0001] The invention relates to an ankle joint motion assisting device, in particular to a quasi-passive ankle joint motion assisting device. Background technique [0002] Walking assist device is a new research field that has emerged in recent years. The assist device can enhance the strength of the lower limbs of the human body and can provide services for the elderly, disabled, soldiers and firefighters to enhance walking ability. Due to the limitation of human body structure , the existing three-degree-of-freedom wearable ankle joint assist device has the following shortcomings: 1. Usually, the internal or external rotation axis is set behind the calf, which is parallel to the internal or external rotation axis of the ankle joint of the human body, but does not coincide. Interference problems will occur, causing inconvenience to users. 2. The existing power assist device needs to carry a large amount of energy during use, which not only brings a burden t...
