Backpack-type walking power assisting device

Abstract

The invention discloses a backpack-type walking power assisting device which comprises a supporting frame, wherein a back plate, straps, a backpack and a size-adjustable waistband are arranged on the supporting frame; a rotatable hip joint is mounted at the lower end of the supporting frame; a pair of lower limb exoskeletons are mounted on the hip joint; each lower limb exoskeleton comprises a thigh bone supporting mechanism, a leg bone supporting mechanism and a foot fixing mechanism; the leg bone supporting mechanism is elastically connected with the foot fixing mechanism; the thigh bone supporting mechanism comprises a thigh bone fixing plate and a first gravity balance mechanism; the leg bone supporting mechanism comprises a leg fixing plate and a second gravity balance mechanism; and the thigh bone fixing plate is elastically connected with the leg fixing plate. The backpack-type walking power assisting device has the advantages that the first gravity balance mechanism and the second gravity balance mechanism are used for balancing the lower limb gravity in a moving process of a human body in real time, thereby enabling a user to walk by following a movement trajectory of a human skeleton and reducing the physical output of the user; a pure mechanical structure design is adopted; the device cannot be influenced by an external environment; and the stability and reliability are high.

Description

technical field [0001] The invention relates to a booster device, in particular to a backpack type booster device for walking on foot. Background technique [0002] In the process of war, disaster rescue or forest fire fighting, roads are often destroyed or there is no road, and mechanical vehicles are blocked or impassable. In order to reach the destination in time, walking has become an inevitable choice. However, human physical strength is Limited, long-term, fast and long-distance hiking can hardly be supported by physical strength alone. In order to help people walking on foot to save physical strength, a backpack-type walking assist device for walking on foot has occurred. The Chinese Utility Model Patent No. 200820175157.8 discloses a backpack-type walking aid for pedestrians on foot. The backpack-type walking aid for pedestrians on foot includes a casing, a power input mechanism, two sets of clutch mechanisms, and two sets of power on and off mechanisms. , two sets...

AI Technical Summary

Problems solved by technology

The mechanical structure and circuit control are combined in the backpack-type walking aid device for pedestrians. On the one hand, its design structure is relatively complicated, the cost is high, and the weight is also heavy, which causes economic and health burdens for users. On the other hand, the circuit The control structure is easily affected by the external environment, and the stability and reliability are not high
