Detailed Description
For a better understanding of the invention, the basic idea of the invention is first described. Specifically, for the wireless charging coil, as long as the diameter ratio of the transmitting coil and the receiving coil and the distance between the two coils are kept constant, the receiving efficiency of energy is not changed. Therefore, the transmitting coil and the receiving coil can be completely changed from a single coil with a larger area into a plurality of coils with smaller areas, and the small coils can be arranged in a certain rule to form a group of coil arrays. Thus, the energy received by each receiving coil is equal to the energy received by the previous single coil, so that in the case of perfect alignment, the energy received by the wireless charging terminal (such as a mobile terminal) is several times that received by the previous single coil, and then the energy is gathered by the charging circuit and charged to the battery, thereby increasing the charging current and reducing the charging time. Because the transmitting coil and the receiving coil are both composed of a plurality of coils, even if the deviation of the central positions of the wireless charging terminal and the wireless charging equipment (such as a wireless charging base) is large, as long as the wireless charging terminal is placed on the wireless charging equipment, part of the coils can be aligned to charge, and therefore the problem that the wireless charging equipment can be charged only by accurate positioning can be solved.
