Design of mechanical devices for the elderly to move and live alone

Abstract

With the increasing aging of the population, the demand for elderly assistance machinery is increasing. By comparing the advantages and disadvantages of the existing elderly assistance devices and analyzing the daily activities and care needs of the elderly, this paper determines the main functions of the mechanical devices for the elderly to move around alone and proposes a general design scheme. Based on the overall design plan, the main mechanisms such as axillary support mechanism, sitting mechanism, posture adjustment mechanism and wheel mechanism were designed, and the operability and stability of the device were improved through the linkage of the variable cell mechanism. Virtual prototype modeling was carried out by solidworks to verify the rationality of the structure. The device not only has better function, but also has simpler structure and lower maintenance cost, which is more suitable for market demand.
