Green travel has bee in the choice to open the car, bus outside of a choice. Recreational vehicle no noise, no pollution, light weight, simple structure, low cost, convenient to use and repair, as both travel and cargo carrying tool, and can be used for physical exercise, which are widely used for people. The aim of this study is to design a new pedal type recreational vehicle, but 4riding, so that the smooth running and labor. This recreational vehicle is mainly suitable for the people in the fitness, sports, leisure, tourism, and other outdoor activities, and more it is to let the people environmental protection consciousness increase and advocating the natural attitude. Recreational vehicle design involves a large number of calculations and technical problems, this design will use the SolidWorks2021, Auto CAD 2021software from a model to a whole recreational vehicle molding introduction. Although in today39。s society, have more choice of new vehicles to choose from, but in the low carbon life today, recreational vehicle as a green vehicle, more people favor. So the recreational vehicle design and analysis research has important significance. 腳踏式休閑車設(shè)計(jì) III 目 錄 摘 要 .....................................................................................................................................
