摘要

One embodiment provides a non-contact power transmitter device including a sealed housing provided at least partially within a surface, and a transmitter coil within the sealed housing configured to inductively transfer power to a power receiver device. The power transmitter device also includes a transmitter control unit coupled to the transmitter coil, a transceiver configured to communicate with the power receiver device, and an electronic processor coupled to the transmitter control unit and the transceiver. The electronic processor is configured to establish, using the transceiver, communication with the power receiver device, and negotiate power transfer requirements between the power transmitter device and the power receiver device. The electronic processor is also configured to control the transmitter coil unit to transfer power to the power receiver device.

說明書

Another embodiment provides a non-contact power transfer system including a power transmitter device and a power receiver device configured to be coupled in a power transfer relationship with the power transmitter device. The power transmitter device includes a flat base portion, and a transmitter coil provided in the flat base portion. The power receiver device includes a flat portion configured to be aligned with the flat base portion of the power transmitter device, and a receiver coil provided in the flat portion. The flat base portion and the flat portion are aligned to axially align the transmitter coil and the receiver coil without an air gap between the flat base portion and the flat portion.

In some constructions, a first magnet is provided in the flat base portion in the center of the transmitter coil, and a second magnet is provided in the flat portion in the center of the receiver coil. When the flat portion is aligned with the flat base portion, the first magnet is coupled to the second magnet due to the magnetic force between the first magnet and the second magnet.
