Low-loss wireless charging magnetic core structure, method and terminal thereof

The invention provides a low-loss wireless charging magnetic core structure, a low-loss wireless charging magnetic core method and a low-loss wireless charging terminal, which are applied to a wireless coupling mechanism transmitting end and a wireless coupling mechanism receiving end, and the magnetic flux density is reduced by changing the thickness of a partial region of a magnetic core, so that the magnetic core loss of the region can be reduced. Therefore, the magnetic induction intensity distribution is uniform, the loss of the magnetic core is greatly reduced, and the performance of the wireless charging coupling mechanism is improved. 本发明提供一种低损耗无线充电磁芯结构、方法及其终端，应用于无线耦合机构发射端和无线耦合机构接收端，通过改变磁芯部分区域厚度来减小磁通密度以能够实现减小该区域的磁芯损耗；这样磁感应强度分布均匀，大幅度降低了磁芯的损耗，提高了无线充电耦合机构的性能。
