设计简介
摘 要
科技的迅猛发展使USB风扇的发展也进入了一个全新的发展阶段。从休闲日用到商务办公;不管是市井平民还是成功人士,在大街,在学校,在医院,在楼层等USB风扇无不闪现着它的倩影。经济的全球化,人与人之间联系的密切化,追求的多样化也必将促使USB风扇的风格,款式造型的多彩化发展。Pro/E,UG等软件的广泛使用使USB风扇的造型不断向高精度方向发展,同时也对设计设计人员提出了更高的要求。本设计是型号为USB风扇的粗略造型设计。其设计内容大致包括:USB风扇材料的选用及分析,USB风扇结部件的分析,三维造型图的绘制,二维工程图的转换等。由于所学知识浅薄,本设计只是粗略造型,旨在了解设计流程,掌握简单的造型方法,熟练运用和深化所学知识(Pro/E造型的实践运用)。

Abstract
The rapid development of science and technology makes the USB fan development has entered a new stage of development. From the casual daily to the business office; whether ordinary civilians or success, in the street, in school, in hospital, on the floor, USB fan are flashed its shadow. The globalization of economy, the close relationship between person and person, the pursuit of diversification will also make the USB fan style, the style of colorful development. Pro/E, UG software is widely used to make the USB fan shape constantly to high accuracy direction, but also to the design personnel raised taller requirement.This design is the model for the USB fan rough design. The design content includes: USB fan material selection and analysis, USB fan node components analysis, three-dimensional shape drawing, 2D engineering drawing conversion. Because the knowledge is dilettante, this design is just a rough shape, aimed at understanding the design process, to grasp the simple modeling methods, proficiency and deepen the knowledge ( Pro/E modeling practice ).
Key words: design, USB fan, Pro/E software, engineering drawing
