Problems solved by technology

[0005] The charging coil of the terminal equipment is usually a solenoid structure prepared by FPC (Flexible Printed Circuit, flexible circuit board). When preparing the charging coil, in order to ensure the manufacturability of the circuit, a certain gap needs to be reserved between adjacent circuits. As a result, the board surface utilization rate of the formed charging coil is low, resulting in low charging efficiency of the terminal equipment

Abstract

The invention discloses a preparation method of a charging coil, a charging module of a terminal device, and a terminal device. The preparation method includes the following steps: preparing a coil main body; preparing an insulating layer in the gap between the lines of the coil main body; A conductive coil is prepared in the gap of the insulating layer, so that the insulating layer is located between the coil main body and the conductive coil. The conductive coil can make full use of the gap between the lines of the coil main body, and the coil main body and the conductive coil jointly play the role of the coil, so that the utilization rate of the board surface of the charging coil is improved, and its charging efficiency is improved accordingly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a preparation method of a charging coil, a charging module of a terminal device, and a terminal device. Background technique [0002] With the escalating needs of users, wireless charging technology has received more and more attention. In order to realize wireless charging, the structure of the terminal device needs to be optimized. [0003] At present, the mainstream wireless charging technology works as follows: [0004] The charging base (transmitter) and the terminal device (receiver) have built-in charging coils respectively, wherein the charging coil of the charging base is the transmitting coil, and the charging coil of the terminal device is the receiving coil. The transmitting coil passes through a certain frequency of alternating current, which generates an alternating magnetic field through electromagnetic induction. After the terminal device is placed on the...
