  • Patent number: 10498175
    Abstract: A wireless power receiving method and a multicoil multiplex wireless power receiving device using same is disclosed. The method includes: a receiving coil for receiving AC signals from a transmitting base station; a rectifying unit for rectifying and converting the AC signal into a DC signal; a multiplexing device for receiving the DC signal from the rectifying unit and thereafter outputting direct current; a communicating and controlling device for modulating the multiplexing device and the receiving coil to feedback the electrical signal to the base station, and monitoring the load outputted. The communicating and controlling device adjusts the feedbacks during the electrical signal of the load abnormal. In the present disclosure, the receiving coil can fix in any position, rather than the receiving coil aligning to a corresponding coil of the base station, which can obtain a normal transmission work between the wireless power receiving device and the base station.

  • Patent number: 10284014
    Abstract: A transceiving wireless power transmission device enclosure herein includes a transmitting and receiving coil, a receiving controller, a transmitting controller and a full-bridge switch connected to the transmitting and receiving coil and the receiving controller and the transmitting controller. When the full bridge switch determines that the transmitting and receiving coil is connected to the receiving controller or the transmitting controller. A near field communication (NFC) modulating unit is connected between the transmitting controller and NFC induction coil. The transmitting and receiving coil can optionally transmit or receive a wireless power according to an actual requirement, the NFC modulating circuit can determine whether an NFC circuit is formed on a receiving end of a smart phone or other electrical products. If the NFC circuit is formed on the receiving end, the transmitting controller is notified to activate an NFC protection to ensure that the NFC circuit can't be damaged.

  • Patent number: 9300151
    Abstract: A wireless charging device of the disclosure is used for carrying out wireless battery charging for an electronic device. The wireless charging device includes a wireless charger, a positioning seat, and an adjusting seat. The positioning seat is fixed with the wireless charger. The positioning seat and the wireless charger collectively form a sliding space. The adjusting seat supports the electronic device. The adjusting seat extends into the sliding space and slides along the sliding space relatively to the positioning seat, to adjust a location of a transmitter coil center of the wireless charger, which results that the transmitter coil center of the transmitter of the wireless charger aligns to a receptor coil center of the electronic device.
