Booster-based hip and knee joint assisted external skeleton mechanism

Abstract

The invention discloses a booster-based hip and knee joint assisted external skeleton mechanism and belongs to the technical field of human body assistance. The booster-based hip and knee joint assisted external skeleton mechanism comprises a connecting external skeleton, a left limb external skeleton and a right limb external skeleton. The right limb external skeleton comprises a body width adjusting external skeleton, a hip joint booster, a thigh external skeleton, a knee joint booster, a shank external skeleton and a baffle plate. Leg lifting action of thighs and shanks can be assisted effectively by the assisted external skeleton mechanism designed by special employees with assisted power on hip and knee joints, so that sport consumption is alleviated and limb dyskinesia is relieved. Two hip joint pitching degrees of freedom and two knee joint pitching degrees of freedom are available. An ultrathin torque motor is used for driving. The mechanism can be attached to the body effectively, so that the mechanism is more compact in structure. Three training modes are available: a tracking mode through which the walking action is smoother, a symmetrical mode which guides a user to bend left and right legs during walking and a pedal mode which adjusts the center of gravity of the user.

Description

technical field [0001] The invention relates to an exoskeleton mechanism, in particular to a hip and knee joint booster exoskeleton mechanism based on a booster, which belongs to the technical field of human body boosting. Background technique [0002] Exoskeleton-assisted robots will improve the ability of the human body to walk and move, and reduce the work intensity of workers. Workers in the manufacturing and logistics industries are faced with a large number of mechanical operations of repeatedly carrying heavy objects every day. The waist, shoulders and other parts are under huge load pressure, which is prone to occupational diseases such as lumbar disc herniation, and at the same time, the work efficiency is not high. This solution provides an exoskeleton power-assisted robot, which is convenient for workers to use during work and reduces the weight on the body during work. [0003] The essence of an exoskeleton is a structure that can be fixed on the human body. It ...

AI Technical Summary

Problems solved by technology

[0005] 1. All kinds of mature driving solutions known at present have the defects of large volume, heavy weight, high noise and high energy consumption. None of the drives can be compared with human muscles

[0006] 2. The wearable exoskeleton robot system has special requirements for battery power. It must not only ensure low power output for a long time (such as walking, carrying weight, etc.), but also have the ability to output high power instantaneously (such as running, jumping, etc.). Such an energy system does not yet exist

[0007] 3. There are also many problems with the flexibility and portability of the structural system. At present, there is no system that can really make people feel comfortable.
