多功能轮椅的研究-轮组机构的设计

Design of research wheel set mechanism for multifunctionalwheelchairAbstractIn real life,wheelchairs have become a mobility tool for the elderly and physicallyhandicapped.The current domestic market can be divided into wheelchairs that can only bewalked on flat or expensive multifunctional wheelchairs,so we designed a This kind ofwheel-crawler compound climbing wheelchair is cheap and can climb stairs.Based on the characteristics of various types of wheelchairs for climbing stairs.The basicplan for the electric wheelchair to climb the stairs has been established,and the mechanicalsystem design and 3D software modeling have been completed.Among them are a wheeledcompound walking mechanism,a mechanical separation system composed of a power outputand a composite power switching mechanism,a seat balance adjustment mechanism and anauxiliary support mechanism.Based on the design of the mechanical system principle,theathletic performance of the wheelchair for climbing stairs is analyzed.According to theanalysis of sports performance,the wheelchair for climbing stairs is excellent in stability andmobility,and can climb obstacles with a vertical height of less than 180 mm and an angle ofless than 35Keywords:Stair-Climbing wheelchair Mechanical system Wheel-Tracked
