However, the present invention is not limited to this.

  The power transmission coil 22 is a first power transmission coil, and, like the power reception coil 14, is configured by a conductor coil wound outward from the central axis, and transmits power in a non-contact manner. The power transmission coil 22 is disposed at a position facing the power reception coil 14 in a state where the switch unit 10 is mounted on the holding unit 20, and transmits power to the power reception coil 14 in a contactless manner. Specifically, the power transmission coil 22 is disposed at a position facing the power receiving coil 14 in a state where the switch unit 10 is mounted on the holding mechanism 21 of the holding unit 20, and transmits power to the power receiving coil 14 in a contactless manner.

  The power transmission circuit 23 includes a DC / AC inverter that converts input DC power into AC power. The power transmission circuit 23 is connected to the W / H 40 by the connector 41, and receives power supply from the power source 51 connected to the W / H 40. The power transmission circuit 23 converts DC power supplied from the power source 51 into AC power and supplies the AC power to the power transmission coil 22 with the switch unit 10 mounted on the holding unit 20.

  The communication coupler 24 is a second communication unit, and is a communication module that performs wireless communication with the communication coupler 15 on the switch unit 10 side using TransferJet (registered trademark) or the like. Similar to the communication coupler 15, the communication coupler 24 includes a printed wiring board (not shown), a coupling electrode, a coaxial connector, and the like.

The connector 41 is, for example, a wiring connector that connects the wiring extending from the holding unit 20 and the W / H 40. The control unit 50 is provided on the vehicle side and performs various controls and processes in accordance with ON / OFF operations on the switch unit 10 mounted on the holding unit 20. The power source 51 is mounted on the vehicle and is configured by a secondary battery such as a battery, for example.

  In the vehicular wireless power feeding system 1 configured as described above, the power receiving coil 14 and the power transmitting coil 22 constitute a pair of contactless power feeding transformers by facing each other. In the non-contact power supply transformer, power can be transmitted from the power transmission coil 22 to the power reception coil 14 in a non-contact manner by various methods such as an electromagnetic induction method and an electromagnetic resonance method. Here, the electromagnetic induction method means that the power transmission coil 22 uses the magnetic induction generated by passing a direct current (AC) through the power transmission coil 22 as a medium to generate electromotive force in the power reception coil 14 from the power transmission coil 22 to the power reception coil 14. This is a method for transmitting power. In the electromagnetic field resonance method, AC power is supplied to the power transmission coil 22 to resonate the power transmission coil 22 and the power reception coil 14 at a specific frequency, and the power reception coil 22 receives power from the power transmission coil 22 using the resonance phenomenon of the electromagnetic field. 14 is a system for transmitting power.

  More specifically, in the non-contact power supply transformer, when power is transmitted from the power transmission coil 22 to the power reception coil 14, the power supply 51 is in a state where the power transmission coil 22 and the power reception coil 14 face each other with an interval therebetween in the axial direction. DC power is converted into AC power of an arbitrary frequency via the power transmission circuit 23 and supplied to the power transmission coil 22. In the contactless power supply transformer, when AC power is supplied to the power transmission coil 22, for example, the power transmission coil 22 and the power reception coil 14 are electromagnetically coupled, and the power from the power transmission coil 22 is not caused by electromagnetic induction or electromagnetic resonance. The power is received by the power receiving coil 14 by contact.

  In the vehicular wireless power supply system 1 configured as described above, when the microcomputer 16 detects, for example, an ON operation on the switch mechanism 11 in a state where the switch unit 10 is mounted on the holding unit 20, the microcomputer 16 stores it in the memory. The status information indicating the status of the switch unit 10 is updated from “OFF” to “ON”. Next, the microcomputer 16 transmits the identification information for identifying the type of the switch unit 10 and the updated state information stored in the memory via the communication coupler 15. Here, the identification information is a unique ID or code assigned to the switch unit 10 in advance. When receiving the identification information and the status information via the communication coupler 24, the communication circuit 25 transmits the identification information and the status information to the control unit 50 via the connector 41 and the W / H 40. The control unit 50 performs various controls based on the received identification information and state information. For example, when the switch unit 10 is a switch for turning on / off an air conditioner, the control unit 50 identifies the air conditioner based on the identification information, and controls the operation of the air conditioner based on the state information. As described above, the control unit 50 identifies the switch unit 10 mounted on the holding unit 20 based on the identification information. Therefore, no matter which holding mechanism 21 among the plurality of holding mechanisms 21 is mounted, the switch unit 10 The type of the unit 10 can be identified, and ON / OFF of the corresponding function can be controlled.

  In the vehicular wireless power feeding system 1 configured as described above, the holding unit 20 provided on the vehicle interior surface 30 is configured such that a plurality of switch units 10 having a power receiving coil 14 for receiving power in a non-contact manner can be attached and detached. Then, power is transmitted to the power receiving coil 14 in a non-contact manner from the power transmitting coil 22 arranged at a position facing the power receiving coil 14 in a state where the switch unit 10 is mounted on the holding unit 20. Thereby, since arrangement | positioning of the switch part 10 can be changed in any of several holding mechanism 21a-21d provided in the holding | maintenance part 20, according to a driver | operator's liking and a difference in dominant arm, switch part 10 The layout can be easily changed. For example, when the driver wants to operate the ON / OFF switches of functions mounted on the vehicle in one place, the corresponding plurality of switch units 10 are held at predetermined positions on the passenger compartment surface 30. The parts 20 can be attached together. In addition, when a left-handed driver wants to operate various switches on the left side toward the steering wheel, the switch unit 10 desired by the driver is placed on the holding unit 20 provided on the left side toward the steering wheel. It becomes possible to install.

  The vehicle wireless power feeding system 1 described above includes a switch unit 10, a holding unit 20, and a power transmission coil 22. The switch unit 10 includes a load 12 and a power receiving coil 14 that supplies power received in a contactless manner to the load 12. The holding | maintenance part 20 is provided in the compartment surface 30, and the switch part 10 is comprised so that attachment or detachment is possible. The power transmission coil 22 is disposed at a position facing the power reception coil 14 in a state where the switch unit 10 is mounted on the holding unit 20, and transmits power to the power reception coil 14 in a contactless manner. Therefore, the vehicle wireless power feeding system 1 is provided on the vehicle compartment surface 30 with the switch unit 10 having the power receiving coil 14 that supplies the load 12 with the power received in a non-contact manner, and the switch unit 10 is detachable at a plurality of positions. The power is transmitted to the power receiving coil 14 in a non-contact manner from a power transmission coil 22 disposed at a position facing the power receiving coil 14 in a state where the switch unit 10 is mounted on the holding portion 20. Therefore, the switch unit 10 can be attached to and detached from a plurality of positions of the holding unit 20 provided on the vehicle compartment surface 30 of the vehicle, and power is supplied to the switch unit 10 mounted on the holding unit 20 in a non-contact manner. Therefore, it is possible to improve the degree of freedom in changing the layout of various switches arranged on the passenger compartment surface 30. In addition, since the plurality of switch units 10 and the holding unit 20 are made wireless, connection work between the switch unit 10 and the W / H 40 becomes unnecessary.

  In addition, the vehicle wireless power feeding system 1 includes a first communication unit that transmits state information indicating a state of the switch unit 10 in a contactless manner when the switch unit 10 is attached to the holding unit 20. The holding unit 20 includes a second communication unit that receives the state information transmitted from the first communication unit, and the second communication unit transmits the received state information to the control unit 50 that controls the vehicle. Thereby, the state (for example, ON or OFF) of the switch unit 10 can be transmitted to the control unit 50 of the vehicle, and the control unit 50 can perform control according to the state of the switch unit 10.

  In the vehicular wireless power feeding system 1, the communication coupler 15 transmits identification information for identifying the type of the switch unit 10 in a state where the switch unit 10 is mounted on the holding unit 20. The communication coupler 24 receives the identification information transmitted from the communication coupler 15 and transmits the received identification information to the control unit 50. Thereby, even when a plurality of types of switch units 10 are mounted on the holding unit 20, the control unit 50 can perform control according to the type of the switch unit 10. For example, when the switch unit 10 is a starter button, the starter button can be taken out of the vehicle, which helps prevent theft of the vehicle.
