摘要

腳踏車，是屬於自行車〈bicycle〉的一種形式，是一種不需要燃料的簡易機械交通工具，在現今的社會上相當普遍，因為它不會浪費任何資源，也不會造成環境污染，且體積小，不會造成交通阻塞，也不需要鋪設大量的柏油道路，省下許多社會資源，速度也不會太快，不會造成重大交通意外，所以也被世界各國鼓勵多加利用。而腳踏車演變至現今依照使用環境的需求，可以概略分為三輪腳踏車、兩輪腳踏車以及單輪腳踏車；而在這當中，又因為使用者的需求增加，進而發展出協力車形式的腳踏車、可摺疊收納的腳踏車，更甚者發展出因應不同年齡層而使用尺寸大小不同的腳踏車。本研究系關於一種腳踏車之切換，兩輪與三輪間變換以及立式與臥式間變換之研究，主要目的是希望利用運動學的角度來進行腳踏車的整體機構設計，以其發展出多功能性質之腳踏車。本研究擬完成現有腳踏車之文獻探討，並對現有腳踏車之文獻進行分類分析整理，發現現有之相關專利文獻絕大多數都是針對單一性能之腳踏車申請，僅有少部份專利申請是針對多功能性，但是多功能性質之腳踏車也常有安裝與拆卸上的問題，故本研究希望發展出單靠機構切換的手續即可完成達到多功能性質之目的。本研究將參考實際腳踏車之相關尺寸進行研究中之概念與車體之變換，並利用相關之運動學機構分析原理，進行運動分析，並以Solid Work軟體繪製3D零件圖與3D組合圖，3D圖面都建構完成後再輔以ANSYS軟體配合分析驗證。

Bikes, a kind of simple mechanic vehicle that does not consume any fuel, are quite general and popular in the modern era and has been widely welcome in many countries for at least the following six reasons: (1) it is portable; (2) it does not bring pollution to our environment; (3) it does not cause traffic jam; (4) it saves energy and natural resources; (5) we do not have to spend any social resources to lay asphalt roads for it; (6) its low speed reduces the risk of serious accidents. Adapting to all possible circumstances under which it may be utilized, bikes can be divided into three types: tricycles, bicycles, and monocycles. Among these, because of the increasing demand of the user, synergy-bikes, foldable bikes, and bikes with different sizes adapted to different age groups are further developed. The content of this study is about the transformation between bicycles and tricycles, and between vertical bikes and horizontal bikes. We aim to design multifunctional bikes in a kinematics point of view. In this study, we make a comprehensive literature review and analysis about bikes. We find that most of the patents for bikes are about single-function bikes, and only few of them are about multifunctional bikes. However, almost these multifunctional bikes have deficits in assembling and dismantling. Therefore, we aim at developing a kind of multifunctional bike with one single mechanical transition. We consult the sizes of real bikes to build up the necessary concepts and the transformation of the bikes. Moreover, under the framework of mechanical analysis of kinematics, we analyze the kinematics of our bikes and with the help of Solid Work, we draw the three-dimensional exploded view and combination view, which are further analyzed with ANSYS.
