Title:
WIRELESS CHARGING TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/016376
Kind Code:
A1
Abstract:
Disclosed is a wireless charging transmission device. The wireless charging transmission device comprises: a transmission coil, a control circuit and a shell. The transmission coil is in the three-dimensional spiral shape, so that magnetic fields are distributed in every certain area, and the magnetic fields are distributed uniformly. The three-dimensional spiral coil is connected to the control circuit with a capacitive to form an LC oscillating circuit to realize wireless charging according to the principle of electromagnetic resonance. Though the invention, the charging device can realize wireless charging when the charging device is placed in arbitrary postures, and can meet the requirement of charging a plurality of charging devices at the same time, and the charging efficiency is high.
