PAGE PAGE 25 多功能轮椅的设计 摘要 轮椅适于下肢残疾、高位截瘫或偏瘫以及年老体弱者使用，是一种比较理想的移动或代步工具。但随着现代社会的不断发展，普通轮椅已经不能满足人们的需求，为此多功能轮椅的研发必将成为一种趋势，在满足基本需求的基础上，设计一种可升降，可平躺得轮椅。通过对驱动方式进行分析和再设计，整体采用四连杆机构，以连杆机构中的死点支持，无需电力驱动，在大大减少了成本的同时，也提高了轮椅的安全性，延长了轮椅的使用期，为新型低成本电动轮椅的设计开发打下了一定基础。 关键字 ： 多功能轮椅，设计，连杆机构 死点 Mechanical design of multifunction wheelchair Abstract Wheelchair is suitable for lower limb disability, paraplegic or hemiplegia and frail elderly use, is a kind of ideal of moving or walking tool. With the continuous development of modern society, the ordinary wheelchair can not meet people's needs, so the research and development of multi-functional wheelchair bound to become a trend. The use of a wheelchair people's economic level, the wheelchair can lie on your back. Wheelchair for electric wheelchair at home and abroad based on the study of the mechanical system, the modern design theory and method, analysis of the driving mode and design again, In greatly reduced the cost at the same time, also improved the security of the wheelchair, delayed, could the wheelchair for the design and development of new low-cost electric wheelchair laid a certain foundation, provides a reference of the drive scheme and frame structure.
