Structure Design and Analysis of Semi-shared Stair-climbing Wheelchair

In view of the growing aging population and the increasing rate of physical disability，and by referring to the design inspiration of shared bicycles，a semi-shared stair-climbing wheelchair is innovatively proposed.A modular design method is adopted to design the folding body and the stair-climbing body of the stair-climbing wheelchair separately. The transmission system and kinematic system of the stair-climbing wheelchair are also studied. A dynamics simulation model is established through Adams to verify the feasibility of the stair-climbing wheelchair.
