Description

technical field [0001] The invention relates to a receiving and sending module of a wireless charging device, in particular to a preparation process of a wireless charging transceiver module and a wireless charging transceiver module. Background technique [0002] With the rapid development of science and technology and the wide application of electronic equipment, people's work and life are increasingly dependent on electronic equipment. Regarding the charging part of electronic equipment, wireless charging technology is also called inductive charging and non-contact charging. It is a new charging technology derived from wireless power transmission technology. Wireless charging technology uses near-field sensing, and the wireless charger transmits energy to the device that needs to be charged. Under normal circumstances, the energy transmitted by the capacitor is very small, which has a lot to do with the small electrode area. Therefore, to meet the power levels required ...

Problems solved by technology

[0007] Although the above patents have mentioned the method of reducing the magnetic loss, the process method cannot fully exert the optimal effect of this method

Please refer to image 3 , the combined structure of the traditional wireless charging receiver coil 1 and magnetic materials. The advantage of this structure is that it is simple to prepare and easy to assemble. The disadvantage is that the shielding and magnetic conduction effects of the shielding sheet cannot be fully utilized, and the power transmission efficiency cannot be maximized.

To sum up, the coil & magnetic material lamination structure used in the existing wireless charging electromagnetic shielding sheet has low charging efficiency; in addition, the existing shielding sheet structure cannot fully utilize the shielding performance of the soft magnetic material and cannot meet the application requirements
