1、 1 毕业设计 课题名称： 专业： 汽车技术服务与营销 班级： 姓名： 学号： 指导： 二一年十二月一日 电动车电路设计 2 摘 要 电动车简而言之就是以电力为驱动。以电力为能源的车。 电路图是人们为了研究和工程的需要，用约定的符号绘制的一种表示 电路结构的图形。通过电路图可以知道实际电路的情况。这样，我们在分 析电路时，就不必把实物翻来覆去地琢磨，而只要拿着一张图纸就可以了； 在设计电路时，也可以从容地在纸上或电脑上进行，确认完善后再进行实 际安装，通过调试、改进，直至成功；而现在，我们更可以应用先进的计 算机软件来进行电路的辅助设计，甚至进行虚拟的电路实验，大大提高了 工作效率。 本文主要
2、说明了，我们设计的电动车的电路结构，分别有灯光电路，电机电 路 2 大类，其中灯光电路又分为：前照灯电路，转向灯电路，刹车灯电路。首先 分别讲述了 3 个灯光电路的设计方案和这样设计的好处， 然后又把 3 个电路并联 成为整个电动车的灯光电路再解决其中可能出现的短路与误亮的错误思想， 最后 就完成了我们整个电动车的灯光电路的设计。 电机电路我们加入了变速设备实现 了电动车变速问题。 关键字：关键字：电路图 电动车 设计 3 Abstract Electric vehicles is to power the drive short. Electricity for the energy of
3、the car. Circuit is that people need to research and engineering, with the convention that the symbol of a circuit drawn graphics. Through the circuit to know the actual circuits. Thus, our analysis of the circuit, you do not have the kind pondering over and over again, as long as holding a drawing
4、on it; in the design of the circuit, they could easily be on paper or computer, and then confirm the actual sound installation, through commissioning, to improve, until the success; and now, we can apply advanced computer software to aid design of the circuit, or even virtual circuit experiment, gre
5、atly improving efficiency. This paper describes our design of the electric car circuit structure, respectively, lighting circuits, electrical circuit 2 categories, including lighting circuits are divided into: head lamp circuit, the turn signal circuit, the brake light circuit. First the circuit is
6、about 3 light design and the benefits of this design, and then again three circuits in parallel into the electric vehicle to resolve the lighting circuit which short-circuit may occur and erroneous ideas of false light, and finally completed our light electric vehicles throughout the circuit design. We joined the variable speed motor circuit equipment to achieve variable speed electric vehicle problems. Keywords: circuit, electric cars, design 4 目 录 中文摘要中
