Design of Ordinary Electric Vehicle Movers

Abstract

To address the growing challenges of disorderly electric bicycle (e-bike) parking and the operational inefficiency caused by electronic rear-wheel locks on shared models, this paper proposes the design of a specialized e-bike mover. Based on an analysis of technical parameters from four typical e-bike models, a worm gear transmission mechanism was selected for its superior self-locking properties and its ability to adjust for various tire diameters. The device was modeled and assembled using SolidWorks, and its structural integrity was validated through static finite element analysis (FEA). The FEA results demonstrate that the maximum von Mises stresses of the transmission shaft (268 MPa) and the main web plate (9.57 MPa) are significantly below their respective yield strengths, with negligible static displacement. These findings confirm that the proposed design possesses sufficient strength and stiffness for reliable operational use. This practical e-bike mover effectively enhances relocation efficiency, reduces urban management costs, and supports the sustainable development of organized urban environments.
