WIRELESS CHARGING COIL

WIPO Patent Application WO/2020/224185

A1

A wireless charging coil, relating to the technical field of wireless charging, and comprising an excitation layer (5) and a coil annular loop formed by winding the same insulating conducting wire. The coil annular loop comprises a first coil annular loop (1) and a second coil annular loop (2). The first coil annular loop (1) is provided on an upper end surface of the excitation layer (5), and the plane where the first coil annular loop (1) is located is parallel to the excitation layer (5). The second coil annular loop (2) surrounds upper and lower end surfaces and both side surfaces of the excitation layer (5). The wireless charging coil utilizes the same insulating conducting wire to design two coil annular loops so that the magnetic field generated after the wireless charging coil is powered on is increased, which improves the excitation effect with respect to the wireless charging coil in the prior art which utilizes the same insulating conducting wire to form only one coil annular loop, and improves the wireless charging efficiency and the practicability of the charging coil.
