Therefore, various countries government, each big Car company are expanding the electric automobile development investment dynamics, speeds up electric automobiles commercialized step. The this paper researchs topic is the electrically operated sightseeing car gross structure design. First briefly introduces electric automobiles history and the present technical water in this article, as well as electric automobile overall conception; Is the complete bikes basic design parameter analysis and the choice; Finally is the electric automobile unit arrangement, introduced the electrical machinery, the battery, the wheel and the vehicle bridges choice in detail, as well as transmission system, driving system, power transmission arrangement form analysis, as well as frames system design; Finally is the parameter examination and the determination. Has even more consolidated my automobile knowledge through this design. Moreover the designed capacity which learns in this and solves the question ability, will have the huge influence and the help to I later study and the work.
