Title:
WIRELESS CHARGING MODULE
Document Type and Number:
WIPO Patent Application WO/2021/114076
Kind Code:
A1
Abstract:
Disclosed is a wireless charging module (100), the wireless charging module (100) comprising a battery (10), a magnetic conductive sheet (20), a primary coil (30), a secondary coil (40) and a transmitting element (50), wherein the magnetic conductive sheet (20) is attached between the battery (10) and the secondary coil (40), the primary coil (30) is arranged at an interval on a side of the secondary coil (40) that is away from the magnetic conductive sheet (20), the transmitting element (50) is attached to a side of the primary coil (30) that is away from the secondary coil (40), the secondary coil (40) is annular, the magnetic conductive sheet (20) is provided with a center area (11) corresponding to a center hole of the secondary coil (40), and a plurality of heat dissipation through holes (12) are provided at the periphery of the center area (11) on the magnetic conductive sheet (20). In consideration of heat dissipation, the heat dissipation through holes (12) are provided in the magnetic conductive sheet (20) by means of die cutting, such that on the premise of not affecting performance, the wireless charging module (100) can be helped to carry out effective heat dissipation, temperature rise of the coils is slowed down, and the usage experience is prevented from being affected due to a module generating heat in an obvious way.
