Abstract

The invention discloses a three-dimensional wireless charging coil. The three-dimensional wireless charging coil comprises a ferrite base, wherein six layers of encircling coils are sequentially arranged on a surface of the ferrite base from top to bottom, each layer of encircling coil comprises a substrate and a copper substrate, the copper substrate is wound around a surface of the substrate, via holes are formed in each substrate, and the copper substrate of each layer is connected with the copper substrate of a previous layer through the via holes in the substrate. Compared with a traditional planar antenna, the three-dimensional wireless charging coil has the characteristics of field intensity, small area, uniform magnetic field distribution and the like, is easy to assemble and is more suitable for multi-coil parallel design, thus, the three-dimensional wireless charging coil is suitably used for a wireless charging emission end coil and a receiving end coil, and is particularlysuitable for miniaturization design of the emission end coil.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a three-dimensional wireless charging coil. Background technique [0002] The field of wireless charging has rapidly penetrated into people's lives, especially in consumer electronics, medical electronics, industrial electronics and other related fields with broad prospects. In particular, mobile phones that support wireless charging will become more and more common, so the demand for wireless charging will also increase. [0003] Wireless charging is divided into magnetic coupling, magnetic resonance, microwave and other forms. However, the standard coil specified by Qi, the authoritative standard organization of the magnetic coupling method, has problems such as uneven magnetic field distribution, low magnetic field strength, and large volume, which may easily cause work blind spots. Contents of the invention [0004] In order to solve the above proble...
