A rehabilitation exoskeleton walking aid based on the conversion of human gravity potential energy

Abstract

The invention relates to the technical field of medical aids, in particular to a rehabilitation exoskeleton walker based on the conversion of human gravity potential energy, wherein the upper and lower ends of the thigh support assembly are respectively hinged to the waist fixed shell and the upper end of the calf support assembly. Fixed lever bracket, the lower part of the calf support assembly is slidingly installed with a triangular support assembly, the spring one is connected between the calf support assembly and the triangular support assembly, the upper part of the triangular support assembly is installed with a pulley for amplifying the stroke, and the lower end of the lifting steel wire is fixed on the calf support On the component, the lower end of the lifting steel wire extends downward, bypasses the stroke amplification pulley, extends upward through the limit hole of the lever bracket, and is fixed on the waist fixing rod. The upper end of the triangular bracket component is fixed with multi-level sawtooth. When the sawtooth slides, the multi-level sawtooth can be inserted and buckled between the two lock hooks to achieve multi-level locking; when the unlocking steel wire is pulled upwards, it is unlocked, which effectively uses energy, does not require batteries, and does not need to worry about battery life.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a rehabilitation exoskeleton walker based on the conversion of human body gravity potential energy. Background technique [0002] Most rehabilitation exoskeletons currently on the market are active, relying on batteries to provide power. The body is large and has a certain weight. When wearing it, the user needs to bear the load brought by the body. Moreover, the battery has limited power storage capacity, and needs to be charged after wearing for a period of time, which is cumbersome to operate. Contents of the invention [0003] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a rehabilitation exoskeleton walker based on the conversion of human gravity potential energy, which realizes effective buffering of the system and efficient conversion of energy, prevents the rebound of the human body, and rea...
