Passive lower limb exoskeleton with load conduction and walking energy saving functions

Abstract

The invention discloses a passive lower limb exoskeleton with load conduction and walking energy saving functions. The passive lower limb exoskeleton mainly comprises a waist fixing assembly, a hip joint moving assembly, a knee joint moving assembly, an ankle joint moving assembly and connections among the assemblies. The passive lower limb exoskeleton belongs to an enhanced passive lower limb exoskeleton so that the passive lower limb exoskeleton can support a heavy object carried on the shoulders of a person and directly conduct the load to the ground, and thus the fatigue feeling of the person in the load bearing process is relieved. Meanwhile, according to the enhanced passive lower limb exoskeleton, energy which should be consumed in the natural movement process of the human body is collected through arranged elastic elements and released at a proper time, and therefore energy consumption of the person in the walking process is reduced. In addition, the exoskeleton is simple in structure and light in weight, so that the exoskeleton has high reliability and good portability.

Description

technical field [0001] The invention relates to the technical field of exoskeleton, in particular to a passive lower extremity exoskeleton with both load conduction and walking energy saving. Background technique [0002] The title of exoskeleton originated from biology and refers to a hard external structure that can provide support and protection for insects and other organisms, similar to the role of bones. The exoskeleton can play three major roles of support, auxiliary movement and protection. There are different classification methods for human exoskeleton according to its functions, power source and other characteristics. According to the realization function, the human exoskeleton can be divided into human performance enhancement type (referred to as enhanced type), disabled auxiliary type (referred to as auxiliary type) and rehabilitation treatment type (referred to as rehabilitation type). According to whether there is external power drive, it can be divided into...

AI Technical Summary

Problems solved by technology

However, the existing enhanced passive lower extremity exoskeletons are rarely designed with the two functions of load conduction and walking energy saving

Also, they are generally less adjustable

Existing designs lack adjustability, making it difficult to adapt to individual users with widely varying physiological parameters

Moreover, their boosting effect is usually not significant, and their flexibility and wearing comfort need to be improved.
