Title:
SHIELDING PIECE FOR WIRELESS CHARGING MODULE AND WIRELESS CHARGING MODULE
Document Type and Number:
WIPO Patent Application WO/2019/227729
Kind Code:
A1
Abstract:
Disclosed by the present invention are a shielding piece for a wireless charging module and a wireless charging module. The shielding piece comprises an outer-ring magnetic sheet and a central magnetic sheet. A hole matching the central magnetic sheet is formed on the outer-ring magnetic sheet. One end of the central magnetic sheet is fixed in the hole, and the other end of the central magnetic sheet protrudes from the outer-ring magnetic sheet. The outer-ring magnetic sheet includes at least one first magnetic conducting layer, said first magnetic conducting layer being a nanocrystalline strip, an amorphous strip or a metal soft magnetic strip; and the central magnetic sheet includes at least two laminated second magnetic conducting layers, and the second magnetic conducting layers are made of a fragmented nanocrystalline strip, a fragmented amorphous strip or a fragmented metal soft magnetic strip. Compared with traditional nanocrystalline shielding pieces, the shielding piece of the present invention uses less laminated nanocrystalline strips in the outer-ring magnetic sheet, which is beneficial to the miniaturization of the shielding piece; moreover, the charging efficiency is also improved to some degree.
