Abstract
Aimed at addressing the problems of difficult maintenance,low efficiency,and potential safety hazards associated with traditional wired charging methods for logistics sorting machines,a bipolar rectangular coupling structure suitable for wireless power supply in sorting systems is proposed.Through structural optimization,a rectangular coupling mechanism featuring semi-encapsulated aluminum plates with bipolar plate-bipolar plate coils is designed.A mathematical model of the wireless power magnetic coupling mechanism is established to analyze the relationships between magnetic flux density,magnetic flux,coil turns,coil area,and self-inductance/mutual inductance.A three-dimensional numerical model of magnetic coupling effects is established based on the COMSOL Multiphysics simulation platform.Systematic investigations are conducted on the effects of different misalignment distances,coil geometries,coil positions,and aluminum plate configurations on the coupling mechanism's self-inductance and mutual inductance.Simulation results demonstrate that compared with circular coupling structures,the proposed rectangular coupling mechanism with semi-encapsulated aluminum plates and bipolar plate-bipolar plate coils exhibits superior anti-misalignment performance,making it more suitable for wireless power supply to logistics sorting machines.关键词
