雙動力輪電動輪椅之機電設計與整合

Abstract

本研究延續上一代學長研發的動力輪系統，將其與整車進行整合設計與改善。文中介紹手輪馬達電動輪椅之研發歷程、現階段手輪馬達架構、以及後續的馬達機構修正，嘗試改善上一代馬達運轉不順，實測結果與模擬結果落差大的問題。另外本文亦對整個輪框與馬達進行整合設計，將原先安裝於輪上的環形馬達進行造型修正，力求讓環形馬達與輪框一體成形，除了對其外觀美化外，也讓馬達有較佳的保護，至於煞車方面也構思了全新的釋放機構，以方便使用者進行手動與電動模式切換，期望藉由本文的設計能使手輪馬達電動輪椅更符合社會需求，達到市場化甚至量產上市的最終目標。

This research intends to improve the running of the dual power wheel system developed by the previous generation, and integrates it with the wheelchair design and improvement for market-oriented production. The historical and technological backgrounds of the powered wheelchair is reviewed, and the structure of rim motors and the modifications of motor mechanism are illustrated. The inconsistancy between motor operation and simulation is improved in this study. In this thesis the integrated design of the whole wheel frame and motor is proposed and implemented. The ring motor originally installed in the wheel is used to have shape correction in order to make the ring motor and wheel frame forming. In addition, the motor has a better protection from dusk and moisture. The brakes of a new release mechanism facilitating the user to switch between manual and electric modes are also designed. The main purpose of this design on rim motor electric wheelchairs is to fit the real requirement of commercialization.
