Title:
TERMINAL WIRELESS CHARGING RECEIVING DEVICE AND TRANSMITTING DEVICE, AND WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/233290
Kind Code:
A1
Abstract:
A mobile terminal wireless charging receiving device. The wireless charging receiving device is used for being disposed inside a mobile terminal and close to a metal rear housing (3) of the mobile terminal, and comprises two coils (701, 702) which are connected to each other, the two coils (701, 702) being located in the same plane and connected in series, and the winding directions of the two coils (701, 702) are opposite to each other, such that magnetic flux directions of the two coils (701, 702) generated on the metal rear housing (3) are opposite to each other. The present invention resolves the problem of a metal rear cover vortex of a mobile terminal including a wireless charging system such as a smartphone, and achieves the effect that the temperature of a metal body and energy loss can be reduced without providing holes or slits in the metal rear cover.
