Abstract With the accelerated process of urbanization, the city becomes more and more crowded, the people are increasingly high demand for convenient travel tools。 However, truly portable means of transport is scanty。 This paper introduced several kinds of scooter on the market simply 。On the basis of the analysis, this subject has designed a riding electric car according to demand for convenient travel。 This electric car has small size, light weight and it is suitable for driving in the city。 Furthermore it is easily to carry into the elevator, the subway and bus。
This design gives the structure design of each part of the electric vehicle and introduce the control mode of the electric vehicle briefly, which is to control the starting and stopping of the electric vehicle by changing the position of the center of gravity。 This paper gives the processing dynamics calculation of the electric vehicle load capacity and climbing ability as well as the acceleration time。 The material of its Frame is aluminum alloy,the density of which is small, so that the overall quality of the electric car is not too large。 The finite element analysis and structural optimization are also carried out for the main load bearing parts。
