摘　　要：设计了一款新型自动爬楼梯轮椅,可帮助残疾人上下楼梯以及平地行走。上下楼梯装置采用腿式结构,由机械脚和轮子交替支撑,模拟人上下楼梯的过程。设置了微调机构,可调节座椅角度,保持座椅始终水平。分析了上下楼梯过程中重心的变化,结果表明该轮椅设计制造合理,可作为残疾人士上下楼梯的代步工具。A new type of automatic stair climbing wheelchair can helps the disabled walking up and down the stairs and the ground is designed.By adopting the leg structure and using the mechanical foot and wheel bearing alternately in the up and down the stairs equipment,the process of up and down the stairs is simulated.The fine-tune mechanism which can be used to adjust seat angle,keep the seats level all the time is set.The change of the gravity center in the process of up and down the stairs is analyzed,the results show that the design of wheelchair is reasonable,a disabled people can use it up and down the stairs instead of walking.
