The Structure Design of a Small Electric Vehicle with Dual Functions of Climbing-Stairs and Driving over Roads

Abstract:

In order to solve the problem of carrying out heavy loads up and down stairs for city residents who live in ordinary building without elevators, this paper designs a special small electric vehicle driven by storage battery, which has dual functions of climbing-stairs and driving over roads with a relatively quick speed based on a key mechanism—triple-wheel mechanism. The main structure and work principle of the small electric vehicle are given and analyzed at first. Then the driving speed over roads and the driving tortures of climbing stairs, which are essential data to design the powers of the driving motors, are calculated and analyzed. Finally the finite element analysis of the most fragile part-trident shaped part is analyzed and interpreted with a simulation model of the software—Solidworks. Due to the adequate and detailed calculations and analysis, the small electric vehicle with the dual functions designed by this paper can offer enough abilities to climb stairs with heavy loads and drive over roads with a considerable speed for residents who living in those buildings without elevators.
