Abstract

The invention belongs to the technical field of wireless electric energy transmission and provides an induction coil for wireless electric energy transmission, and aims at solving problems of large size and low transmission efficiency of an induction coil in the prior art. The induction coil comprises insulating films and conductor patterns. The conductor pattern on a same insulating film comprises a single turn or multiple turns. The conductor patterns on the insulating films are mutually overlapped in the stacked direction of the insulating films. The invention also provides a manufacture method of the induction coil for wireless electric energy transmission and a wireless charging system equipped with the induction coil. According to the induction coil, the multiple insulating films equipped with the single-turn or multi-turn conductor patterns are stacked, the conductor patterns are overlapped in the stacked direction, and magnetic fields generated by electrifying the conductor patterns are nearly overlapped. Therefore, the total magnetic field intensity is increased in direct proportion to the number of conductor pattern layers on the insulating films, and the converting efficiency between electric energy and magnetic energy is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to an induction coil for wireless power transmission and a manufacturing method thereof, and also relates to a wireless charging system with the induction coil for wireless power transmission. Background technique [0002] With the development of electronic communication technology, more and more people use all kinds of portable electronic devices, which put forward higher and higher requirements for charging equipment. There are many inconveniences in wired charging methods, and wireless energy transmission technology has been developed accordingly. Wireless power transmission is the use of a special device to convert the power of the power supply into energy that can be transmitted wirelessly, and then convert the wirelessly transmitted energy back to electrical energy at the receiving end, thereby achieving wireless charging for electrical equipment...
