Abstract
A wireless charging device includes a transmitting-end ferrite core and a transmitting-end coil, wherein the transmitting-end ferrite core have a bottom plate and two upright plates for forming a U-shaped structure defining a charging space therein. One or more wireless power receiving apparatus is put in the charging space. The wireless power receiving apparatus includes a receiving-end coil and a receiving-end ferrite plate, wherein the receiving-end ferrite plate is vertical to the two upright plates. When electrical current flows through the transmitting-end coil to generate an electromagnetic field in the charging space, the electromagnetic field via the two upright plates goes through each of the receiving-end ferrite plates to form an electromagnetic loop. Each of the receiving-end coils generates a charging electrical current induced by the electromagnetic field. Therefore, the present invention can achieve wireless charging to more than one wireless power receiving apparatus at the same time.
