In FIG. 1, 1 is a vehicle such as a plug-in type electric vehicle or hybrid vehicle, 2 is a motor for traveling, and 3 is a battery. The vehicle 1 travels by driving the traveling motor 2 with the electric power of the battery 3. A vehicle non-contact charging device 4 that charges a battery 3 mounted on a vehicle 1 has a generator 6 connected to the battery 3 via a converter 5. The generator 6 is attached to the floor or frame of the vehicle body. The battery 3 is supplied with electric power generated by the generator 6 via the converter 5 and is charged.

The external charger 10 amplifies the alternating current generated by the alternating current generator 11 with the amplifier 12 and passes the amplified current through the multipolar coil 14. When an alternating current flows, the multipolar coil 14 positioned close to the conductor 8 generates a rotating magnetic field 15 of the rotating surface along the vehicle side surface of the vehicle body panel 9, and causes an eddy current to flow through the conductor 8 in the rotating magnetic field 15.

In FIG. 2, 1 is a vehicle such as a plug-in type electric vehicle or hybrid vehicle, 2 is a motor for traveling, and 3 is a battery. The vehicle 1 travels by driving the traveling motor 2 with the electric power of the battery 3. A vehicle non-contact charging device 4 that charges a battery 3 mounted on a vehicle 1 has a generator 6 connected to the battery 3 via a converter 5. The generator 6 is attached to the floor or frame of the vehicle body. The battery 3 is supplied with electric power generated by the generator 6 via the converter 5 and is charged. The generator 6 includes an input shaft 7 that drives the generator 6 and can be driven to rotate from the outside of the vehicle 1. A conductor 8 is connected to the input shaft 7. The conductor 8 is disposed such that the rotation surface is along the vehicle side surface of the vehicle body panel 9.
The vehicle non-contact charging device 4 includes an external charger 20. The external charger 20 includes an inverter 21 that converts a commercial power source to generate a predetermined alternating current, a rotating motor 22 that is driven by the generated alternating current, a rotating plate 23 that is rotated by the rotating motor 22, And a plurality (even number) of magnets 24 configured so that magnetic poles (N, S) are alternately arranged in the rotation direction of the rotating plate 23. The magnet 24 generates a rotating magnetic field 25 having a rotating surface along the vehicle side surface. The rotating magnetic field 25 is rotated by passing an eddy current through the conductor 8 in the rotating magnetic field 25.

車両用非接触充電装置４は、バッテリ３を充電する際に、発電機６の入力軸７に設けた導体８を覆う車体パネル９に、外部充電器２０の磁石２４を近づけて車両１を停止させる。外部充電器２０は、インバータ２１で発生した交流電流を回転用モータ２２に供給して回転板２３により複数個の磁石２４を回転させる。回転板２３の回転方向に磁極が交互に並ぶように配置した磁石２４は、車体パネル９の車両側面に沿う回転面の回転磁界２５を生成し、この回転磁界２５内の導体８に渦電流を流して回転させる。導体８の回転は、入力軸７を回転させて発電機６を駆動し、発電する。発電機６が発電した電力は、コンバータ５を介してバッテリ３に供給され、充電する。
このように、車両用非接触充電装置４は、外部充電器２０の回転磁界２５で車両１に搭載した発電機６の入力軸７を回転させるので、共鳴コイルを用いて電力を伝える変調方式の非接触充電装置よりも損失が少なく、効率的に発電できる。また、変調回路が不要であり、車載する充電装置を省略できる結果、車両上の乗員スペースを確保できる。
また、外部充電器２０は、車両側面に沿う回転面の回転磁界２５を生成する磁石２４とこの磁石２４を回転させる回転用モータ２２とを備えることで、導体８と回転磁界２５との強力な磁気回路を形成して、大きな回転力を発電機６に伝えることができる。 When charging the battery 3, the vehicle non-contact charging device 4 stops the vehicle 1 by bringing the magnet 24 of the external charger 20 close to the vehicle body panel 9 covering the conductor 8 provided on the input shaft 7 of the generator 6. Let The external charger 20 supplies the alternating current generated by the inverter 21 to the rotating motor 22 and rotates the plurality of magnets 24 by the rotating plate 23. The magnets 24 arranged so that the magnetic poles are alternately arranged in the rotation direction of the rotating plate 23 generates a rotating magnetic field 25 of the rotating surface along the vehicle side surface of the vehicle body panel 9, and an eddy current is applied to the conductor 8 in the rotating magnetic field 25. Flow and rotate. The rotation of the conductor 8 generates electric power by driving the generator 6 by rotating the input shaft 7. The electric power generated by the generator 6 is supplied to the battery 3 through the converter 5 and charged.
In this way, the vehicle non-contact charging device 4 rotates the input shaft 7 of the generator 6 mounted on the vehicle 1 by the rotating magnetic field 25 of the external charger 20, so that a modulation system that transmits power using a resonance coil is used. There is less loss than a non-contact charging device and power can be generated efficiently. Further, the modulation circuit is unnecessary, and the on-vehicle charging device can be omitted. As a result, a passenger space on the vehicle can be secured.
In addition, the external charger 20 includes a magnet 24 that generates a rotating magnetic field 25 of a rotating surface along the vehicle side surface and a rotating motor 22 that rotates the magnet 24, so that the conductor 8 and the rotating magnetic field 25 are powerful. A large rotational force can be transmitted to the generator 6 by forming a magnetic circuit.

なお、前記導体８は、外部充電器１０側の磁気発生源である多極コイル１４、あるいは外部充電器２０側の磁気発生源である磁石２４と、単純な磁気回路を形成する構造であるので、両極（Ｎ、Ｓ）に両端が対応する単純な棒形状のものが望ましい。棒形状の導体８の長手方向の長さは、回転する導体８として車載する際に許容できる長さであって、なるべく長い方が大きなトルクを与えられ、発電力を高めることができる。
回転する導体８は、露出させないために、樹脂製などの非磁性体であり、背面側に鉛直かつ平坦な偏平空間を形成できる形状の車体パネルで覆うことが望ましい。
導体８および入力軸６は、回転磁界１５、２５との空間距離を短縮して、車体パネル９の外表面に近づけることにより、回転磁界１５、２５との強力な磁気回路を形成して、大きな回転力を発電機６に伝える事ができ、効率的である。
また、前記導体８および入力軸７は、実際の車両１に搭載する場合、外力を受ける可能性を考慮して、破損を軽減する構造を加えておくことが望ましい。
例えば、入力軸７は、破損を軽減する構造として、発電機６側で片持ち支持する構造とし、導体８および発電機６に対して着脱可能な中空管形状とする。この入力軸７は、その中間部分に狭窄部を形成して相対的に脆弱にし、狭窄部の変形によって外力のエネルギを吸収する構造とする。また、この入力軸７は、中間部分にて分割し、互いにキー溝やスプラインにより雌雄嵌合させ、径方向にピンを貫通させて回転を伝達可能で摺動不能とし、外力によってピンを破断させて中間部分を相対摺動させ、エネルギを吸収する構造としても良い。
さらに、発電機６の入力軸７にワンウェイクラッチを設けることで、車両１に搭載される発動機（エンジン等）の動力により発電機６を駆動して発電させたり、また、多極コイル１４に交流電流を供給して回転磁界１５を生成し、あるいは磁石２４を回転させて回転磁界２５を生成することで発電をさせたりすることができる。ワンウェイクラッチなどの作動連結と切断（相互自由に回転）を切換えられるクラッチを設ける場合は、発電機６と入力軸７の間に設ける。 The conductor 8 has a structure that forms a simple magnetic circuit with the multipolar coil 14 that is the magnetic source on the external charger 10 side or the magnet 24 that is the magnetic source on the external charger 20 side. A simple rod shape having both ends corresponding to both poles (N, S) is desirable. The length of the rod-shaped conductor 8 in the longitudinal direction is a length that can be tolerated when it is mounted on the vehicle as the rotating conductor 8, and as long as possible, a larger torque can be applied to increase the power generation.
The rotating conductor 8 is preferably a non-magnetic material such as resin so as not to be exposed, and is preferably covered with a vehicle body panel having a shape capable of forming a vertical and flat flat space on the back side.
The conductor 8 and the input shaft 6 form a strong magnetic circuit with the rotating magnetic fields 15, 25 by shortening the spatial distance with the rotating magnetic fields 15, 25 and approaching the outer surface of the vehicle body panel 9. The rotational force can be transmitted to the generator 6 and is efficient.
In addition, when the conductor 8 and the input shaft 7 are mounted on an actual vehicle 1, it is desirable to add a structure that reduces damage in consideration of the possibility of receiving an external force.
For example, the input shaft 7 is structured to be cantilevered on the generator 6 side as a structure that reduces damage, and has a hollow tube shape that can be attached to and detached from the conductor 8 and the generator 6. The input shaft 7 has a structure in which a narrowed portion is formed at an intermediate portion thereof to make it relatively fragile, and energy of external force is absorbed by deformation of the narrowed portion. In addition, the input shaft 7 is divided at an intermediate portion, and is fitted with a male and a female by a keyway and a spline, and the pin is penetrated in the radial direction so that rotation can be transmitted and non-slidable. The intermediate portion may be relatively slid to absorb energy.
Further, by providing a one-way clutch on the input shaft 7 of the generator 6, the generator 6 is driven by the power of the engine (engine or the like) mounted on the vehicle 1 to generate power, or the multipolar coil 14 It is possible to generate electric power by supplying an alternating current to generate the rotating magnetic field 15 or by rotating the magnet 24 to generate the rotating magnetic field 25. When providing a clutch that can be switched between operating connection and disconnection (rotation freely), such as a one-way clutch, it is provided between the generator 6 and the input shaft 7.

この発明は、効率的に発電でき、また、車両上の乗員スペースを確保できるものであり、車両に搭載したバッテリの充電だけでなく、他の交通機関に搭載したバッテリや据え置き型のバッテリの充電にも応用可能である。   The present invention is capable of generating power efficiently and securing a passenger space on the vehicle. In addition to charging a battery mounted on the vehicle, charging of a battery mounted on other transportation or a stationary battery is also possible. It can also be applied to.
