Development of detachable power assist system for the wheelchair which can be supported for independence and self^support of the user

1.轮椅是腿部残疾人和老年人使用的良好福利设施。历史悠久，诚信度高。因此，它成为残疾人的象征性标志。现有的轮椅重量轻，可以实现小转弯，而且有康复效果。因此，它可以方便地在家庭和医院使用。但是，当长距离购物时，它成为用户的身体负担。这样的时间。电动轮椅可以减轻使用者的身体负担，但失去了康复效果。那么，轮椅上可简单拆卸的电动助力系统就是能够支持轮椅使用者的有效系统。本研究旨在开发一种可拆卸式轮椅助力系统.每年的研究结果（1）1997年：第1年对轮椅的动力辅助系统进行了参考，实验性地制作了用于行驶数据收集的轮椅，进行了各种行驶环境下的行驶实验。(2)1998年：第2年将行程数据映射到计算机中，设计了助力系统，并进行了实验生产，确认了助力系统的工作情况。(3)1999年：去年对助力系统进行了改进，实现了助力系统的性能改进，并对助力系统进行了评价实验.总结与展望达到了三年来的研究目的。希望将来能将这一结果转化为实际应用。

1. Research pointThe wheelchair is good welfare equipment which leg handicapped and old people use. And, it have long history and the integrity is high. Therefore, it becomes a symbol-mark of the disabled. Present wheelchair is light weight and the small turn is possible, besides there is the rehabilitation effect. Therefore, it is convenient in order to use in home and hospital. But, it become the physical burden of the user, when long distances such as shopping. Such time. The motoerized wheelchair can reduce the physical burden of the user, but the rehabilitation effect is lost. Then, the simply detachable electric power assist system in the wheelchair is effective system which can support wheelchair users. This study aimed the development of easy detachable power assist system for the wheelchair.2. Research result of each years(1) 1997: 1st yearThe reference on the power assist system of the wheelchair was carried out.The wheelchair for the travel data collection was produced experimentally.The driving experiment under all travel environments was carried out.(2) 1998: 2nd yearThe travel data was mapped in the computer.The power assist system was designed, and it was produced experimentally.The operation of the power assist system was confirmed.(3) 1999: last yearThe power asist system was improved, and it's the improvement performace was realize.The evaluation experiment of power assist system was carried out.3. Summary and future developmentResearch purpose for the 3 years was achieved. It wants to turn this result to the practical application in future.
