The X plane, Y plane and Z plane are all perpendicular to each other.

Regardless of which of the above four resonant rings, when the transmitting resonant ring is working, after the transmitting sub-coil whose normal line coincides with the X-axis is energized, a magnetic field is formed on both sides of the sub-coil plane and in the direction of the X-axis. At the same time, After the transmitting sub-coil whose normal line coincides with the Y axis is energized, a magnetic field is formed on both sides of the sub-coil plane and in the Y-axis direction. Similarly, after the transmitting sub-coil whose normal line coincides with the Z-axis is energized, the A magnetic field is formed on both sides of the plane and in the direction of the Z axis, so that an omnidirectional 3D magnetic field is formed in the spherical area covered by the three transmitting sub-coils; in this 3D magnetic field, a receiving resonant ring is placed, regardless of the receiving Regardless of the orientation of the coil or the plane of the receiving coil, the receiving coil can cut the lines of magnetic force to generate electric energy to realize wireless power supply.
