Problems solved by technology

However, because only a small part of the energy radiated by the external magnetic field acts on the induction coil in the portable electronic device and is converted into electrical energy, the induction coil generates an induced current to charge the battery, and a large part of the magnetic field energy is scattered to the surroundings or is transferred from the surroundings. The electronic components are absorbed and then converted into heat energy, and the charging efficiency is low
In this regard, in order to be able to receive more energy radiated by the external magnetic field to convert into electrical energy, the induction coil may be set longer, however, the increase in the length of the induction coil will also increase the loss in the transmission process, so that the charging less efficient
In addition, the existing wireless charging portable electronic devices do not have a matching wireless charging device. If the strength of the changing magnetic field outside is increased in order to increase the charging current, it may interfere or magnetize the wireless charging portable electronic device. other internal components

Abstract

A wireless charging type portable type electronic device comprises a housing and two wireless charging modules which are arranged in the housing, wherein each of wireless charging modules comprises a magnetic induction block and a coil module, each of coil modules comprises an induction coil and is used for generating induction current under the action of a changing magnetic filed outside the housing, one end of each of magnetic induction blocks is close to the magnetic filed outside the housing, the other end of each of magnetic induction blocks corresponds to the induction coil, and the magnetic induction blocks are used for being magnetized under the action of the changing magnetic filed outside the housing and strengthening the filed intensity of the magnetic filed which is acted on the induction coils.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a wireless charging portable electronic device and a matching charging device. Background technique [0002] Existing portable electronic devices that can be charged wirelessly generally have an induction coil inside, so as to generate an induced current through the induction coil to induce changes in an external magnetic field, thereby charging the battery. However, because only a small part of the energy radiated by the external magnetic field acts on the induction coil in the portable electronic device and is converted into electrical energy, the induction coil generates an induced current to charge the battery, and a large part of the magnetic field energy is scattered to the surroundings or is transferred from the surroundings. The electronic components are absorbed and then converted into heat energy, and the charging efficiency is low. In this regard, in order to be able to...
