Title:
WIRELESS CHARGING COUPLING MECHANISM, AND WIRELESS POWER TRANSMISSION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/005625
Kind Code:
A1
Abstract:
The present invention relates to the technical field of wireless power transmission, and in particular to a wireless charging coupling mechanism, and a wireless power transmission system and method. The wireless charging coupling mechanism comprises an energy emitting apparatus and an energy receiving apparatus, wherein the energy emitting apparatus comprises an energy emitting coil; the energy receiving apparatus comprises an energy receiving coil; the energy emitting coil comprises a first coil group and a second coil group; the first coil group and the second coil group have the same shape; and the first coil group generates a magnetic field in an X horizontal direction, and the second coil group generates a magnetic field in a Y horizontal direction. In the present invention, horizontal magnetic fields in two dimensions, i.e. in an X-axis direction and in a Y-axis direction, are generated by means of two groups of coils, such that an energy emitting coil can realize wireless power transmission regardless of an energy receiving coil being placed in the X-axis direction or the Y-axis direction. Compared with traditional individual double-D-type coils, one degree of freedom is expanded, thereby realizing multiple-degrees-of-freedom wireless charging for an energy receiving end.
