Title:
ELECTRONIC DEVICE, AND WIRELESS CHARGING COUPLING STRUCTURE AND POWER SUPPLY DEVICE OF STYLUS
Document Type and Number:
WIPO Patent Application WO/2024/027188
Kind Code:
A1
Abstract:
An electronic device, and a wireless charging coupling structure and a power supply device of a stylus. The wireless charging coupling structure comprises a transmitting module and a receiving module; the transmission module is arranged on the power supply device, wherein the power supply device can specifically be interactive apparatuses such as a mobile phone and a tablet computer, and the stylus can be used as an input component of these interactive apparatuses; the transmitting module comprises a coil component, the coil component is provided with two planar coils arranged in a staggered manner, and current directions of the two planar coils are opposite; the receiving module is arranged on the stylus, the receiving module is provided with a solenoid, and the solenoid is suitable for coupling magnetic fields of the two planar coils for power generation. In the transmitting module of the wireless charging coupling structure, the two planar coils are used as the coil component, and the size of the planar coils in the axial direction thereof is small, so that the mounting space of the planar coils in the axial direction can be reduced, and the heat dissipation performance can be improved.
