多功能爬階手推車之設計與系統整合

本研究目的建置具備安全移載及簡易搭載人體之功能電動手推車，以獨特性、高度模組化設計上，並且提供穩定性和操作方便之攀爬式手推車，讓身心障礙人員的移動及搬運作業勞工，更有確保安全與效率。本研究參考國外廠商所研發之成品並設計的連桿機構，使用SolidWorks電腦輔助設計軟體設置3D立體視圖，並進行動態模擬及應力分析，設計出符合其攀階功能的零件，再製作爬階手推車之各部位零件以及架設電器迴路，並且設計簡易拆卸輪椅模組化，以及增加補助爬坡動力系統，最後進行負載測試檢驗成果。在本研究設計產品對於國外規格上大致相同，但在模組多樣性與成本上差異許多，對於勞工與身心障礙人員工作環境上的改善有一定程度的助益，而往後的載具研究具有相當程度的價值。

並列摘要

The main purpose of this research is to develop a new electrical trolley which possesses carrying capability of heavy loads and human body. The development of such novel product hold multi-function and modularize design. By using computer-aided-design software SolidWorks to set up 3D system model, the structure analysis and dynamic simulation have been demonstrated in this study. The system integration has been conducted by mechanism, electrical circuit, sensor and actuator. Thus, the operation performances have been verified in experimentation. Consequently, the proposed novel device will own slope/stair climbing and descending.It also exhibits auto balancing control and prevents falling down device. Moreover, it owns much cheaper cost down than the foreign products in construction. Expectantly, the proposed design explored in this thesis preserves the potential to be developed into commercial products. It not only provides useful machine for material handling, but also can promote assistive devices market.
