Artificial limb arm joint with multiple freedom degrees

Abstract

The invention provides an artificial limb arm joint with multiple freedom degrees. The artificial limb arm joint comprises a driving component and an output component; the driving component comprisesa first driving assembly and a second driving assembly which are arranged in parallel, the output component comprises an output end, a driven bevel gear, a first driving bevel gear and a second driving bevel gear, the driven bevel gear is fixedly connected with the output end, the first driving bevel gear and the second driving bevel gear are arranged oppositely, the driven bevel gear is orthogonally meshed with the first driving bevel gear and the second driving bevel gear, the first driving assembly is used for driving the first driving bevel gear to rotate, and the second driving assembly is used for driving the second driving bevel gear to rotate. According to the artificial limb arm joint with multiple freedom degrees, two driving motors with the first driving assembly and the seconddriving assembly act on the two driving bevel gears of the output component at the same time, finally inner rotation, outer rotation, buckling, extending and swinging are realized at the output end ofthe driven bevel gear, and the artificial limb arm joint is low in integral weight, small in radial size, low in cost, good in generality and high in practicability.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a multi-degree-of-freedom prosthetic arm joint. Background technique [0002] With the continuous occurrence of various natural disasters, industrial injuries, car accidents, trauma and other accidents, as well as the impact of some diseases, the number of patients who have to amputate is increasing year by year. For amputee patients, the most common recovery measure is to install a prosthetic limb. By wearing prosthetics, you can complete some corresponding actions to obtain basic self-care ability. With the continuous development of science and technology, more and more disabled people can improve their quality of life and even restore some basic working ability by wearing auxiliary devices such as prostheses. However, the existing prosthetic limbs that can be provided on the market are either purely mechanical transmission structures, which cannot re...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the disadvantages that the existing prosthetic joint structure usually uses a single motor to drive a single degree of freedom, resulting in limited movement ability and the heavy weight of the motor, resulting in a large overall weight of the prosthesis and insufficient wearing comfort and practicability.
