a mechanical device

Abstract

The embodiment of the invention relates to a mechanical device. The mechanical device comprises a base plate, two back backboards, a cross beam, a fixing plate, air cylinders, wheel set connecting parts, second shaft connecting parts, first turning wheels, second turning wheels, third turning wheels, third shaft connecting parts, fourth turning wheels, arc-shaped connecting parts, leg stops and steel wires. Each backboard is fixedly connected with one air cylinder. The steel wires are connected with piston rods through steel wire connecting parts. By penetrating through holes of the wheel set connecting parts, the steel wires wind across the first turning wheels and the second turning wheels forwardly, and wind across the third turning wheels reversely. The steel wires wind across the fourth turning wheels forwardly and are further connected with the wheel edges of the fourth turning wheels. When the air cylinders operate, the piston rods are pressed into the corresponding air cylinders, and the steel wire connecting parts drive the steel wires to rotate around the first turning wheels and the second turning wheels. By rotating around the third turning wheels, the third shaft connecting parts can be driven to rotate around a second rotating shaft, the fourth turning wheels are further driven to rotate around a fourth rotating shaft and thus the arc-shaped connecting parts and the leg stops are driven to rotate around the fourth rotating shaft. The mechanical device is portable, low in price, high in sensitivity, safe and reliable.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an exoskeleton device for assisting human body to straighten the waist. Background technique [0002] Mechanical exoskeleton, also known as "exoskeleton armor" or "exoskeleton armor", has a structure similar to that of an insect's exoskeleton, which can be worn on the human body to provide protection, extra power or ability, and enhance human body functions. It is used in medical rehabilitation, military, personal ability improvement and other fields. Many wearable exoskeleton devices have been announced in the prior art, and their functions include weight-bearing walking, lifting heavy objects, medical assisted rehabilitation, replacement of human amputated limbs, individual combat uniforms, and the like. Some use motors as the power source, and some use pneumatic muscles as the power source. Various sensors detect and judge the movement intention of the human body, assist the human body ...

AI Technical Summary

Problems solved by technology

However, if the wearable exoskeleton device in the prior art wants to achieve a higher degree of flexibility, it needs more sensor devices and a more complicated structure, resulting in a heavier device and a higher price, which is difficult for ordinary users to bear.
