In the illustrated example, the primary coil 7 is inserted into the secondary coil 10 incorporated in the grip 18 or the like of the end portion 11 of the bar handle 1, so that a gap G having an equal interval or a substantially equal interval exists. The outer fitting is positioned.
The gap G may be formed as an air gap, which is a space gap, or / and may be formed as a thick wall of the housing 19 or the grip 18. The term is used in a meaning including both cases. In the former case, it is physically and electrically non-contact, and in the latter case, it is physically contacted but not electrically contacted.

  (3) Then, on the condition of such plug 14 connection and proximity positioning of the primary coil 7, power supply and charging to the battery 4 are started.

(4) That is, the primary coil 7 on the power feeding unit 5 side and the secondary coil 10 on the charging unit 8 side are magnetically coupled, and magnetic flux passes through the secondary coil 10 to induce induction in the secondary coil 10. Electric power is generated.
By such mutual induction action of electromagnetic induction, electric power is supplied from the primary circuit 6 on the power supply unit 5 side to the secondary circuit 9 on the charging unit 8 side of the vehicle 3, and the mounted battery 4 is charged. Is done.

  (5) When the power supply is completed (charging is completed), the plug 14 is removed and the connector connection between the plug 14 and the outlet 15 on the external power supply 12 side is released, or / and the secondary coil 10 is connected to the primary coil 7. This is implemented by releasing the proximity-corresponding positioning and pulling out and removing the secondary coil 10 from the external fitting state.

(6) Now, according to the non-contact power feeding device 2 of the present invention, the following points are obtained. First, in the non-contact power feeding device 2 of the present invention, the secondary coil 10 on the charging unit 8 side is incorporated in the grip 18 or the like of the end 11 of the bar handle 1.
When feeding power, the primary coil 7 on the power feeding unit 5 side is positioned close to the secondary coil 10 and attached to the end 11 of the bar handle 1, for example, by external fitting positioning, Power feeding is performed. Thus, the charging operation to the battery 4 is simple and easy.

(7) Further, in the non-contact power feeding device 2 of the present invention, the secondary coil 10 on the charging unit 8 side and the power feeding unit 5 at the end 11 of the bar handle 1 that is easily noticeable by the vehicle 3 during power feeding. The primary coil 7 on the side is brought into a proximity corresponding position.
Therefore, there is no possibility of forgetting that the charging operation is being performed or forgetting to remove the secondary coil 10 after the end of charging.

  (8) In the non-contact power feeding device 2 of the present invention, the primary coil 7 is positioned close to the secondary coil 10 and attached to the end 11 of the bar handle 1, and in the illustrated example, the external fitting is positioned. The power supply is started with almost no effort. This eliminates the possibility of contact failure and disconnection due to insertion / removal.

(9) In the non-contact power feeding device 2 of the present invention, the primary coil 7 and the secondary coil 10 have a structure in which the coil conductors 7 'and 10' are covered with insulation. Moreover, the secondary coil 10 is interposed between the pipe 20 and the grip 18, or is built in the grip 18. In addition, it is easy to coat the primary coil 7 with a resin or the like (for example, interior in the housing 19).
As a result, the primary coil 7 and the secondary coil 10 have no exposed portions of the conductive portions and are excellent in waterproof surfaces.

(10) Furthermore, in the primary circuit 6 on the power feeding unit 5 side of the non-contact power feeding device 2 of the present invention, the alternating current from the external power source 12 is once converted into a low direct current of 24V DC or 12V DC by the controller 16. The power is transmitted through the external cable 13. Therefore, there is no danger of electric shock.
As for the action, it is as above.

<< Development of the present invention >>
By the way, the following 1st, 2nd, 3rd structure can be considered further about the non-contact electric power feeder 2 using the bar handle 1 of this invention.
First, the shapes of the primary coil 7 and the secondary coil 10 are as follows.
That is, in the non-contact power feeding device 2 of the illustrated example, as the primary coil 7 and the secondary coil 10, the coil conductors 7 ′ and 10 ′ are wound in a spiral shape as described above to form a wire ring shape. Eggplants were used (see FIG. 1 (1) and FIG. 2 (1)).
However, the present invention is not limited to such a wire-shaped primary coil 7 and secondary coil 10, and it is possible to employ other various shapes of primary coil 7 and secondary coil 10. is there.

For example, the flat primary coil 7 and the secondary coil 10 which are substantially flat and have a multi-turn method can also be used.
That is, the coil conductors 7 'and 10' coated with insulation are wound a plurality of times in a circular or square spiral while maintaining a parallel positional relationship in parallel on the same plane, so that there is no overall unevenness. It is also possible to adopt a flat and thin flat shape that is flat and thin, and for example, an annular or substantially flange-like shape in which a central space is formed.
Then, the primary coil 7 and the secondary coil 10 having such flat and corresponding shapes are assembled or attached to the end portion 11 of the bar handle 1. Further, a primary coil 7 and a secondary coil 10 in which such a flat shape is wound into a cylindrical shape are also conceivable.
The shapes of the primary coil 7 and the secondary coil 10 are as described above.

Secondly, the alarm device 23 is as follows.
As shown in FIG. 1A, the non-contact power feeding device 2 including the alarm device 23 is also conceivable. The alarm device 23 includes an alarm unit 24, a control unit 25, and a frequency changing unit 26.
The alarm means 24 is attached to the vehicle 3 and can be alarmed by the buzzer 27 or the like.
The control means 25 is attached to the vehicle 3, that is, the secondary circuit 9 on the side of the charging unit 8, and the secondary coil 10 is pulled out from the primary coil 7 or the plug 14 is plugged out of the outlet 15 during power feeding at a predetermined frequency. Is pulled out and the power supply is interrupted, the alarm means 22 is caused to perform an alarm.
That is, as described above, in the non-contact power feeding device 2, high-frequency alternating current with a predetermined frequency is used as power feeding alternating current. When it is detected that the secondary coil 10 is pulled out from the primary coil 7 or the plug 14 is pulled out from the outlet 15 due to theft or mischief in the middle of power feeding at such a predetermined frequency, this is a condition. As a result, an alarm execution signal is sent from the control means 25 of the alarm device 23 to the alarm means 24. Accordingly, an alarm is performed by the alarm means 24 such as the buzzer 27.
That is, although the power supply to the vehicle 3 such as a motorcycle takes a long time, if the vehicle 3 is stolen in the middle of course, the primary coil 7 is naturally connected from the secondary coil 10 or the plug 14 from the outlet 15. Pulled out. Then, the alarm device 23 described above continuously alerts the stolen vehicle 3 during the escape movement.
In the illustrated example, the control means 25 is constituted by a microcomputer or a sequencer, and is provided in the controller 21. In the figure, 28 is a battery for self-power supply of the alarm means 24. In the case of theft, the battery 4 mounted on the vehicle 3 may be disconnected, and an independent battery 28 is attached so that an alarm is maintained even in such a case.

On the other hand, the frequency changing unit 26 is attached to the primary circuit 6 on the power feeding unit 5 side, and can change a predetermined frequency for power feeding. And by changing the predetermined frequency, the alarm by the control means 25 and the alarm means 24 is disabled.
That is, the illustrated frequency changing means 26 can change the predetermined frequency of the high-frequency alternating current used for power feeding by operating the key 29 and is attached to the controller 17 on the power feeding unit 5 side.
When the primary coil 7 is pulled out from the secondary coil 10 at the end of power supply, the frequency changing means 26 first changes the predetermined frequency for power supply to a different frequency by operating the key 29. Then, the control means 25 determines that the power supply is not completed but the power supply is terminated, and does not determine that the power supply is interrupted at a predetermined frequency even if the primary coil 7 is pulled out. Therefore, the alarm execution signal is not sent from the control means 25 to the alarm means 24, and no alarm is executed.
In this way, power supply ends without warning. After that, it is necessary to return to the original predetermined frequency by the frequency changing means 26 by operating the key 29 again.
The alarm device 23 is as described above.

Third, the electric field coupling method is as follows.
In the illustrated example, based on the mutual induction action of electromagnetic induction, the primary circuit 6 and the primary coil 7 on the power feeding unit 5 side, the secondary circuit 9 and the secondary coil 10 on the charging unit 8 side disposed in the vehicle 3 are illustrated. In addition, non-contact power feeding is performed based on the electromagnetic coupling between the primary coil 7 and the secondary coil 10 located in the proximity corresponding positions.
However, the present invention is not limited to the magnetic field coupling method in which power is transmitted and received using the magnetic field lines and the magnetic field induced as described above, and the electric field that transmits and receives electric power using the induced electric field lines and the electric field. It is also possible to perform non-contact power feeding by a coupling method.
That is, the proximity corresponding position exists with a slight gap G from the primary electrode of the primary circuit 6 on the power supply unit 5 side to the secondary electrode of the secondary circuit 9 on the charging unit 8 side disposed in the vehicle 3. Non-contact power feeding may be performed based on electric field coupling between the two electrodes.
