Design and Strength Analysis of the Wheelchair Switching Mechanism

Abstract:

Based on studying the existing electric wheelchairs for disabled are not well adapted to a variety of road conditions, broken through the structure of traditional wheelchairs, a design proposal that can make electric wheelchair achieve the function of climbing stairs and walking was putted forward and a novel mechanism was designed. The mechanism can make the crawler chassis and the wheels of wheelchair switch when needed, and make the wheelchair travel freely and flexible on the ground or on the stairs. The finite element model of the mechanism was built, and the strength analysis was carried out. The strength analysis provide the theoretical basis for the prototype manufacture.
