ABSTRACT
II
This design with the purpose of making a carriage with the electronic of the Corolla car, the function of this set is that imitate the actual work circumstance of the charging system, the illumination system, the signal system and the meter system .by practice demonstrate and the process of expel breakdown, student can deepen the knowledge of each electronic component and entire electronic system, thereby attain the goal of integrate theory with practice.
This design is based on the basic requirements first,and then confirm the total design project.Adopt the electric appliances system of the corolla car, electric motor and storage battery to provide power supply for the experiment pedestal.In this design,mainly complete the design of experiment pedestal and flat piece, charging system , the composition of component and the connection of electric appliances component.
