Abstract

The invention relates to a wireless charging device, and belongs to the technical field of wireless charging. The wireless charging device comprises a wireless charging coils which comprises an excitation layer, a first coil annular loop and a second coil annular loop. The first coil annular loop is arranged in parallel on the upper end surface of the excitation layer. The periphery of the first coil annular loop is provided with an electromagnetic shielding plate formed by magnetic conductive materials.The electromagnetic shielding plate is fixed on the upper end surface of the excitation layer, and the height of the electromagnetic shielding plate on the upper end surface of the excitation layer is higher than that of the first coil annular loop and the third coil annular loop on the upper end surface of the excitation layer. The second coil annular loop is arranged around the upper and lower end surfaces and two side surfaces of the excitation layer. The side of the second coil annular loop on the upper end surface is disposed adjacent to the side of the first coil annular loop. The wireless charging device can improve the wireless charging efficiency and can also shield the radiation scattering generated by the charging coil in the process of transmitting energy and has a good electromagnetic shielding effect.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a wireless charging device. Background technique [0002] With the development of modern society, electronic equipment is constantly updated, and people put forward higher requirements for the performance and functions of electronic equipment. The traditional charging method brings a lot of inconvenience to people's life when it is used, and the wireless charging method has emerged as the times require, which solves the inconvenience caused by the traditional charging method using charging wires. The wireless charging method is mainly based on the principle of electromagnetic induction. It is convenient and fast without the need for charging wires to contact the mobile phone device. However, the disadvantage is that the charging efficiency is lower than the traditional wired charging method. How to improve the charging efficiency is a difficult problem in wi...
