Power transfer device
A power transfer device disclosed herein is a console installed in a vehicle. The console includes a power transfer panel and a wireless power transfer portion. The power transfer panel outputs microwaves receivable by a built-in power receiver antenna in an electronic device. The wireless power transfer portion in which the power transfer panel is disposed therein can hold the electronic device. A bottom wall, sidewalls, and a cover that define the wireless power transfer portion include microwave shields that shield the microwaves.
1. A power transfer device installed in a vehicle, the power transfer device comprising:
a power transfer component outputting microwaves receivable by a power receiver in at least one electronic device;
a holding portion including walls defining a holding space for holding the at least one electronic device and in which the power transfer component is disposed, wherein
the walls include shields to shield the microwaves, and
the power transfer component includes at least two output portions that output the microwaves; and
a phase shifter that controls a phase of the microwaves output from at least one of the output portions for increasing an intensity of the microwaves at a specified point, wherein
the phase shifter shifts a high intensity point at which the intensity of the microwaves is higher in a space in the holding portion in which the at least one electronic device is placeable by controlling the phase of the microwaves.
2. The power transfer device according to claim 1 , wherein
the walls include a cover that is pivotable between a closed position to close an opening of the holding portion through which the at least one electronic device is inserted and an open position to uncover the opening, and
the power transfer device further comprises a switching mechanism to switch the power transfer component from off to on when the cover is pivoted to the closed position and from on to off when the cover is pivoted from the closed position to the open position.
3. The power transfer device according to claim 2 , further comprising:
a sealing between an opening edge of the holding portion and the cover so that the sealing is brought in close contact with the opening edge of the holding portion and the cover to shield the microwaves when the cover is at the closed position.
4. The power transfer device according to claim 1 , wherein
the walls include an upper wall included in an upper section of the holding portion or a lower wall included in a lower section of the holding portion, and
the power transfer component is attached to the upper wall or the lower wall.
5. The power transfer device according to claim 1 , further comprising:
a communication component that establishes wireless communication with the at least one electronic device, wherein
the communication component is attached to one of the walls of the holding portion.
6. The power transfer device according to claim 1 , wherein
the holding portion is configured to hold a plurality of electronic devices, and
the holding portion includes a stopper to hold the plurality of electronic devices unaligned in a traveling direction in which the microwaves output from the power transfer component travel.
7. The power transfer device according to claim 1 , wherein
the shields include an artificial magnetic conductor that reflects incident electromagnetic waves with a phase rotation of 0°.
8. The power transfer device according to claim 1 , wherein
the shields are formed from an electromagnetic shielding material that shields predefined frequencies.
9. The power transfer device according to claim 1 , wherein
the shields are microwave reflectors that reflect the microwaves,
a microwave concentration area in which the microwaves reflected by the microwave reflector are concentrated is formed in the holding portion, and
the holding portion includes a stand on which the at least one electronic device is placed in the microwave concentration area.
10. The power transfer device according to claim 9 , wherein
the holding portion is configured to hold a plurality of electronic devices, and
the holding portion includes a stopper to arrange the plurality of electronic device in the microwave concentration area.
11. The power transfer device according to claim 10 , wherein
the stopper holds the plurality of electronic devices unaligned in a traveling direction in which the microwaves output from the power transfer component travel.
12. The power transfer device according to claim 1 , wherein
the holding portion is included in an armrest, a console, or a door pocket in the vehicle.
13. A power transfer device installed in a vehicle, the power transfer device comprising:
a power transfer component outputting microwaves receivable by a power receiver in at least one electronic device;
a holding portion including walls defining a holding space for holding the at least one electronic device and in which the power transfer component is disposed, wherein
the walls comprise: shields to shield the microwaves; and a cover that is pivotable between a closed position to close an opening of the holding portion through which the at least one electronic device is inserted and an open position to uncover the opening;
a communication component attached to one of the walls of the holding portion and that establishes wireless communication with the at least one electronic device;
a fitting groove that is formed with an opening edge of the opening of the holding portion;
a sealing disposed in the fitting groove, wherein
the sealing is brought in close contact with the opening edge of the holding portion and the cover to shield the microwaves when the cover is at the closed position.
