Abstract: Aiming at the problem that folding electric tricycle occupied larger space and heavier weight after being folded, the problems of folding mechanism and material of folding electric tricycle were studied. Firstly, a portable folding electric tricycle was designed, the main folding part of the folding electric tricycle was designed by “X” structure, and the mainly body material was made by aluminum alloy. Then, the handling stability of the vehicle was analyzed, the turning radius and ultimate lateral acceleration of the vehicle were calculated theoretically, kinematic analysis of folding mechanism was carried out by ADMAS, and the strength of the whole vehicle under three working conditions were analyzed by HYPERMESH. Finally, according to the design , the prototype was made, and the folding and practical manned test of folding electric tricycle were carried out. The results indicate that, the turning radius of the folding electric tricycle is 800 mm, the ultimate lateral acceleration is 0.3 g, the folding mechanism moves smoothly without jamming, the ideal ergonomic design is adopted in this unit, the maximum stress of the frame is 55.26 MPa under the three working conditions, the design of the folding electric tricycle can meet the strength requirements, and the design goal of miniaturization, lightness and portability is realized.
Key words: folding mechanism; light weight design; handing and stability analysis; kinematic analysis; strength analysis; strength test
