Abstract: Medical caring and rehabilitation device has been designed with the purpose of solving problems for those patients with lower limb paralysis and older people who have mobility difficulties,and yet there is a lack of proper medical equipment currently in the market.The structure and its function of this device are introduced in details,including the design parameters,electric and manual lifting mechanism,adjustment mechanism and folding mechanism etc.According to the first generation of prototype design experience and repeated proof,finally confirmed by foot slider and as a design scheme of the manual,and complete all the parts of the equipment of 3D modeling and the whole machine assembly in the AUTODESK Inventor CAD development environment,at the same time with the help of MATLAB simulation platform,the key state of mechanism motion analysis is completed.Results show that this device has sufficient structural strength,stiffness and stability,which meets the requirements for the expected design specification.

Key words: rehabilitation training device institution, static structure analysis, stability analysis
