At present, the aging of population is increasing, more and more people pay attention to the medical care related equipment. As a device used to help the elderly live independently and travel easily, the detachable bed chair combines the electric wheelchair and the nursing bed, and can be switched between the wheelchair and the nursing bed at will when used. The scientific and reasonable structure design also plays an important role while the function is improving. In this paper, aiming at some problems existing in the leg and back lifting mechanism of the device, the finite element software ANSYS Workbench is used to analyze the force of the important parts existing in the structure and improve its structural performance through optimization design. The results show that the stress of the original part is large and uneven after loading, while the stress distribution of the optimized part is uniform and the overall strength is improved under the same load. Through this optimization design, it provides a more substantial theoretical basis for the follow-up improvement of the product, indirectly promotes the development of the medical device industry, and has a certain research value.
