特開２００９−１５９６８３号公報JP 2009-159683 A

送電素子と受電素子の結合による非接触充電においては、送電電極と受電電極の間の距離の変動があると、無線電力伝送効率に変動がある。したがって、電力の安定供給のためには、送電素子と受電素子の距離の変動を抑えることが望ましい。このためには、送電素子に対する受電器の位置決めを強固にすることが望ましい。   In non-contact charging by combining a power transmitting element and a power receiving element, if the distance between the power transmitting electrode and the power receiving electrode varies, the wireless power transmission efficiency varies. Therefore, in order to stably supply power, it is desirable to suppress fluctuations in the distance between the power transmitting element and the power receiving element. For this purpose, it is desirable to firmly position the power receiver with respect to the power transmitting element.

本発明は上記点に鑑み、送電素子と非接触で結合して非接触給電を行うと共に位置決め用の磁石を有する受電器において、送電素子に対する受電器の位置決めを従来よりも強固にする提供することを目的とする。   In view of the above points, the present invention provides a power receiving device that is coupled to a power transmission element in a non-contact manner to perform non-contact power feeding and has a positioning magnet, and that the positioning of the power receiving device with respect to the power transmission element is made stronger than before. With the goal.

このように、１個以上の磁石は、主構造部材の外側に配置され、それにより、受電素子と送電素子とが結合する際、１個以上の磁石と磁性体とが、間に主構造部材を挟まずに磁性体と対向可能となっている。このようになっていることで、供給回路等を支持するために比較的分厚い部材となっている主構造部材の分だけ、１個以上の磁石と磁性体の間隔を短縮し、吸引力をより強くすることができる。   As described above, the one or more magnets are disposed outside the main structural member, whereby when the power receiving element and the power transmitting element are coupled, the one or more magnets and the magnetic body are interposed between the main structural member. It can be opposed to the magnetic body without sandwiching the gap. In this way, the distance between the one or more magnets and the magnetic body is reduced by the amount of the main structural member that is a relatively thick member to support the supply circuit and the like, and the attraction force is further increased.

（第１実施形態）
以下、第１実施形態について説明する。図１に示すように、本実施形態の非接触給電システムは、建物または車両において実現され、受電器１、壁２、送電シート３、給電アダプタ５を有している。この非接触給電システムは、送電シート３から受電器１に電界結合方式で非接触給電を行う。 (First embodiment)
The first embodiment will be described below. As shown in FIG. 1, the contactless power supply system of the present embodiment is realized in a building or a vehicle, and includes a power receiver 1, a wall 2, a power transmission sheet 3, and a power supply adapter 5. This non-contact power feeding system performs non-contact power feeding from the power transmission sheet 3 to the power receiver 1 by an electric field coupling method.

壁２は、建物の壁として、車両の車体として実現される磁性体（例えば強磁性体）である。壁２としては、永久磁石でない鉄製でもよいし、永久磁石であってもよい。この壁２には、送電シート３が貼り付けられている。   The wall 2 is a magnetic body (for example, a ferromagnetic body) realized as a vehicle body as a building wall. The wall 2 may be made of iron that is not a permanent magnet, or may be a permanent magnet. A power transmission sheet 3 is attached to the wall 2.

送電シート３は、壁２に接着される。この送電シート３は、絶縁部材３０、給電線３１ａ、給電線３１ｂ、一方側送電電極３２ａ、他方側送電電極３２ｂ、一方側送電電極３３ａ、他方側送電電極３３ｂ、一方側送電電極３４ａ、他方側送電電極３４ｂを備えている。   The power transmission sheet 3 is bonded to the wall 2. The power transmission sheet 3 includes an insulating member 30, a power supply line 31a, a power supply line 31b, one side power transmission electrode 32a, the other side power transmission electrode 32b, one side power transmission electrode 33a, the other side power transmission electrode 33b, one side power transmission electrode 34a, and the other side. A power transmission electrode 34b is provided.

絶縁部材３０は、壁２の一部または全部を覆い、一方側の面を壁２に向け、他方側の面を受電器１に向けるシート形状の樹脂部材である。この絶縁部材３０は、壁２側の面が壁２に接着剤等で接着される。そして、給電時、受電器１側の面が受電器１と接触する。この絶縁部材３０は、内包する部材３１ａ、３１ｂ、３２ａ、３２ｂ、３３ａ、３３ｂ、３４ａ、３４ｂを保護する。   The insulating member 30 is a sheet-shaped resin member that covers part or all of the wall 2, with one surface facing the wall 2 and the other surface facing the power receiver 1. The insulating member 30 has a wall 2 side surface bonded to the wall 2 with an adhesive or the like. And the surface by the side of the power receiver 1 contacts with the power receiver 1 at the time of electric power feeding. The insulating member 30 protects the included members 31a, 31b, 32a, 32b, 33a, 33b, 34a, and 34b.

給電線３１ａは、導体であり、絶縁部材３０内に埋め込まれる。この給電線３１ａは、給電アダプタ５の２つの出力端子の一方と電気的に接続し、一方側送電電極３２ａ、３３ａ、３４ａと電気的に接続する。   The power supply line 31 a is a conductor and is embedded in the insulating member 30. The power supply line 31a is electrically connected to one of the two output terminals of the power supply adapter 5, and is electrically connected to the one-side power transmission electrodes 32a, 33a, and 34a.

給電線３１ｂは、導体であり、絶縁部材３０内に埋め込まれる。この給電線３１ｂは、給電アダプタ５の２つの出力端子の他方と電気的に接続し、他方側送電電極３２ｂ、３３ｂ、３４ｂと電気的に接続する。   The power supply line 31 b is a conductor and is embedded in the insulating member 30. The power supply line 31b is electrically connected to the other of the two output terminals of the power supply adapter 5, and is electrically connected to the other power transmission electrodes 32b, 33b, and 34b.

一方側送電電極３２ａ、３３ａ、３４ａの各々は、一枚の板形状の導体であり、絶縁部材３０内に埋め込まれる送電素子である。これら一方側送電電極３２ａ、３３ａ、３４ａの各々は、壁２および絶縁部材３０と平行に配置される。そして一方側送電電極３２ａ、３３ａ、３４ａの各々は、給電時に受電器１の電極（後述する一方側受電電極１１２ａ、他方側受電電極１１２ｂ）と平行に対向し、電界を発生させる。また、一方側送電電極３２ａ、３３ａ、３４ａの各々は、給電線３１ａと電気的に接続され、給電時に、受電器１の一方側受電電極１１２ａと容量結合する。一方側送電電極３２ａ、３３ａ、３４ａの各々は、送電素子に対応する。   Each of the one-side power transmission electrodes 32 a, 33 a, and 34 a is a single plate-shaped conductor and is a power transmission element embedded in the insulating member 30. Each of these one-side power transmission electrodes 32 a, 33 a, 34 a is arranged in parallel with the wall 2 and the insulating member 30. Each of the one-side power transmitting electrodes 32a, 33a, and 34a is opposed to the electrodes of the power receiver 1 (one-side power-receiving electrode 112a and the other-side power-receiving electrode 112b, which will be described later) in parallel, and generates an electric field. Each of the one-side power transmission electrodes 32a, 33a, and 34a is electrically connected to the power supply line 31a, and is capacitively coupled to the one-side power reception electrode 112a of the power receiver 1 during power feeding. Each of the one side power transmission electrodes 32a, 33a, and 34a corresponds to a power transmission element.

他方側送電電極３２ｂ、３３ｂ、３４ｂの各々は、一枚の板形状の導体であり、絶縁部材３０内に埋め込まれる。これら他方側送電電極３２ｂ、３３ｂ、３４ｂの各々は、壁２および絶縁部材３０と平行に配置される。また他方側送電電極３２ｂ、３３ｂ、３４ｂの各々は、給電時に受電器１の受電シート１１と平行に対向し、電界を発生させる。また、他方側送電電極３２ｂ、３３ｂ、３４ｂの各々の各々は、給電線３１ｂと電気的に接続し、給電時に、受電器１の一方側受電電極１１２ａと容量結合する。他方側送電電極３２ｂ、３３ｂ、３４ｂの各々は、送電素子に対応する。   Each of the other power transmission electrodes 32b, 33b, and 34b is a single plate-shaped conductor, and is embedded in the insulating member 30. Each of the other power transmission electrodes 32 b, 33 b, 34 b is arranged in parallel with the wall 2 and the insulating member 30. Each of the other-side power transmission electrodes 32b, 33b, and 34b faces the power receiving sheet 11 of the power receiver 1 in parallel during power feeding and generates an electric field. Each of the other power transmission electrodes 32b, 33b, and 34b is electrically connected to the power supply line 31b, and is capacitively coupled to the one power reception electrode 112a of the power receiver 1 during power supply. Each of the other side power transmission electrodes 32b, 33b, and 34b corresponds to a power transmission element.

なお、一方側送電電極３２ａと他方側送電電極３２ｂが隣り合って配置されて一組の電極対を構成し、一方側送電電極３３ａと他方側送電電極３３ｂが隣り合って配置されて更に別の一組の電極対（図２中ではコンデンサとして記載）を構成し、一方側送電電極３４ａと他方側送電電極３４ｂが隣り合って配置されて更に別の一組の電極対を構成する。このように、送電シート３においては、複数組の電極対が複数の位置に配置されている。そして受電器１は、これら複数の電極対のいずれか１つに対向して配置されることで、当該電極対から非接触で給電を受ける。   The one side power transmission electrode 32a and the other side power transmission electrode 32b are arranged next to each other to form a pair of electrodes, and the one side power transmission electrode 33a and the other side power transmission electrode 33b are arranged next to each other to form another pair. A pair of electrode pairs (described as capacitors in FIG. 2) is configured, and the one side power transmission electrode 34a and the other side power transmission electrode 34b are arranged adjacent to each other to form another set of electrode pairs. Thus, in the power transmission sheet 3, a plurality of pairs of electrodes are arranged at a plurality of positions. The power receiver 1 is arranged so as to face any one of the plurality of electrode pairs, and thus receives power from the electrode pairs in a non-contact manner.

以下では、一方側送電電極３３ａ、他方側送電電極３３ｂを一組の電極対の代表として説明する。ただし、他の送電シート３内の電極対についても、一方側送電電極３３ａ、他方側送電電極３３ｂと同じことが言える。   Hereinafter, the one-side power transmission electrode 33a and the other-side power transmission electrode 33b will be described as representatives of a set of electrode pairs. However, the same can be said for the electrode pairs in other power transmission sheets 3 as the one-side power transmission electrode 33a and the other-side power transmission electrode 33b.

シールド３５は、一枚のシート形状の導体であり、絶縁部材３０内に埋め込まれる。また、シールド３５は、その厚み方向と垂直な方向に、絶縁部材３０と同等の広がりを有する。またシールド３５は、壁２、絶縁部材３０と平行に配置される。そしてシールド３５は、一方側送電電極３２ａ、３３ａ、３４ａの各々と給電線３１ａの間、かつ、他方側送電電極３２ｂ、３３ｂ、３４ｂの各々と給電線３１ｂの間に介在する。また、シールド３５は、給電線３１ａ、３１ｂ、一方側送電電極３２ａ、３３ａ、３４ａ、他方側送電電極３２ｂ、３３ｂ、３４ｂと導通しない。このようになっていることで、シールド３５は、シールド３５の受電器１側に対する給電線３１ａ、３１ｂの電界の影響を低減することができる。   The shield 35 is a single sheet-shaped conductor and is embedded in the insulating member 30. Further, the shield 35 has the same extent as the insulating member 30 in the direction perpendicular to the thickness direction. The shield 35 is disposed in parallel with the wall 2 and the insulating member 30. The shield 35 is interposed between each of the one-side power transmission electrodes 32a, 33a, 34a and the power supply line 31a, and between each of the other-side power transmission electrodes 32b, 33b, 34b and the power supply line 31b. Further, the shield 35 is not electrically connected to the power supply lines 31a and 31b, the one side power transmission electrodes 32a, 33a, and 34a, and the other side power transmission electrodes 32b, 33b, and 34b. With this configuration, the shield 35 can reduce the influence of the electric field of the power supply lines 31 a and 31 b on the power receiver 1 side of the shield 35.

給電アダプタ５は、建物内または車両内の、送電シート３から離れた目立たない場所に配置され、送電シート３に電力供給を行う装置である。この給電アダプタ５は、ＡＣＤＣ変換器５１、ＤＣＡＣ変換器５２、送電側同調整合部５３を有している。   The power feeding adapter 5 is a device that is disposed in an inconspicuous place away from the power transmission sheet 3 in the building or vehicle and supplies power to the power transmission sheet 3. The power supply adapter 5 includes an ACDC converter 51, a DCAC converter 52, and a power transmission side tuning matching unit 53.

ＡＣＤＣ変換器５１は、商用電源から受けた交流を直流に変換すると共に降圧してＤＣＡＣ変換器５２に供給する。ＤＣＡＣ変換器５２は、ＤＣＡＣ変換器５２から供給された直流を高周波（例えば５００ｋＨｚ以上数十ＭＨｚ以下の高周波）の交流に変換して送電側同調整合部５３に出力する。このように、ＡＣＤＣ変換器５１、ＤＣＡＣ変換器５２は、商用電源から非接触用の高周波の交流を生成する。   The ACDC converter 51 converts alternating current received from a commercial power source into direct current and steps down the voltage to supply it to the DCAC converter 52. The DCAC converter 52 converts the direct current supplied from the DCAC converter 52 into a high-frequency (for example, a high frequency of 500 kHz to several tens of MHz) alternating current, and outputs the alternating current to the power transmission side tuning matching unit 53. Thus, the ACDC converter 51 and the DCAC converter 52 generate non-contact high-frequency alternating current from the commercial power supply.

送電側同調整合部５３は、コンデンサ、トランス、コイルを有し、２つの入力端子がＤＣＡＣ変換器５２と電気的に接続する。また、送電側同調整合部５３の２つの出力端子のうち一方が給電線３１ａに電気的に接続し、他方が給電線３１ｂに電気的に接続する。そして送電側同調整合部５３は、一方側送電電極３３ａおよび他方側送電電極３３ｂから成る電極対とＤＣＡＣ変換器５２の同調および整合を実現する。なお、送電側同調整合部５３のトランスは昇圧も行う。この結果、高電圧かつ高周波の交流が一方側送電電極３３ａと他方側送電電極３３ｂに印加される。なお、ＡＣＤＣ変換器５１で降圧して送電側同調整合部５３で昇圧するのは、ＤＣＡＣ変換器５２に印加される電圧を抑えてＤＣＡＣ変換器５２の故障率低下および変換効率向上を実現するためである。   The power transmission side tuning matching unit 53 includes a capacitor, a transformer, and a coil, and two input terminals are electrically connected to the DCAC converter 52. In addition, one of the two output terminals of the power transmission side tuning matching unit 53 is electrically connected to the feeder line 31a, and the other is electrically connected to the feeder line 31b. The power transmission side tuning and matching unit 53 realizes tuning and matching between the electrode pair including the one side power transmission electrode 33a and the other side power transmission electrode 33b and the DCAC converter 52. Note that the transformer of the power transmission side tuning matching unit 53 also boosts the voltage. As a result, a high voltage and high frequency alternating current is applied to the one side power transmission electrode 33a and the other side power transmission electrode 33b. Note that the ACDC converter 51 steps down the voltage and the power transmission side tuning matching unit 53 steps up the voltage to suppress the voltage applied to the DCAC converter 52 and realize a reduction in the failure rate and an increase in conversion efficiency of the DCAC converter 52. It is.

次に、受電器１について説明する。受電器１は、給電時に図１に示すように送電シート３に取り付けられることで、一方側送電電極３３ａ、他方側送電電極３３ｂに対向して取り付けられて位置決めされる。そして、その位置決めされた状態で、一方側送電電極３３ａ、他方側送電電極３３ｂから受電器１に給電される。この際、受電器１は、送電シート３が発生した電界を捕捉、降圧、整流、出力安定化を行って内部の機能部２１へ電力を供給する。   Next, the power receiver 1 will be described. The power receiver 1 is attached to the power transmission sheet 3 as shown in FIG. 1 during power feeding, so that the power receiver 1 is attached and positioned facing the one side power transmission electrode 33a and the other side power transmission electrode 33b. In the positioned state, power is supplied to the power receiver 1 from the one-side power transmission electrode 33a and the other-side power transmission electrode 33b. At this time, the power receiver 1 captures the electric field generated by the power transmission sheet 3, performs step-down, rectification, and output stabilization, and supplies power to the internal functional unit 21.

Furthermore, among the front and rear directions, the direction from the power receiver 1 to the power transmission sheet 3 is defined as the front direction, and the direction from the power transmission sheet 3 to the power receiver 1 is defined as the rear direction.

Screw 22a and screw 22b. The power receiver 1 receives power from the first power transmission electrode 33 a and the other power transmission electrode 33 b of the power transmission sheet 3 in a non-contact manner and supplies the power to the function unit 21, thereby operating the function unit 21.

In FIG. 8, illustration of the power supply line 42 is omitted.

内部プレート１５は、樹脂製または金属製の部材であり、図７に示すように、コイル１４ａの切り欠き部およびトランス１４ｂ用の切り欠き部が形成された板形状を有している。この内部プレート１５は、ネジ１８ａ、１８ｂによって主構造部材１３内に固定されることで、コイル１４ａおよびトランス１４ｂを支持する。   The internal plate 15 is a member made of resin or metal and has a plate shape in which a notch for the coil 14a and a notch for the transformer 14b are formed as shown in FIG. The internal plate 15 supports the coil 14a and the transformer 14b by being fixed in the main structural member 13 by screws 18a and 18b.

基板支柱１７ａ、１７ｂは、それぞれ、樹脂製または金属製の棒形状の部材であり、図７に示すように、内部プレート１５と基板１９ａの間に配置される。基板支柱１７ａの一端がネジ１６ａによって内部プレート１５に固定され、他端がネジ２０ａによって基板１９ａに固定される。また、基板支柱１７ｂの一端がネジ１６ｂによって内部プレート１５に固定され、他端がネジ２０ｂによって基板１９ａに固定される。基板支柱１７ａ、１７ｂがこのように固定されることで、内部プレート１５と基板１９ａの間隔が保持される。   Each of the substrate columns 17a and 17b is a rod-shaped member made of resin or metal, and is disposed between the internal plate 15 and the substrate 19a as shown in FIG. One end of the substrate column 17a is fixed to the internal plate 15 by a screw 16a, and the other end is fixed to the substrate 19a by a screw 20a. Further, one end of the substrate support column 17b is fixed to the internal plate 15 by a screw 16b, and the other end is fixed to the substrate 19a by a screw 20b. By fixing the substrate support columns 17a and 17b in this way, the distance between the internal plate 15 and the substrate 19a is maintained.

実装部１９は、主構造部材１３の内部およびコイル１４ａ、トランス１４ｂの後側かつ機能部２１の前方に配置され、基板１９ａ、整流部１９ｂ、ＤＣＤＣ変換器１９ｃ等を有している。基板１９ａには、コンデンサ１４ｃ、整流部１９ｂ、ＤＣＤＣ変換器１９ｃ等が実装されている。   The mounting portion 19 is disposed inside the main structural member 13 and behind the coil 14a and the transformer 14b and in front of the functional portion 21, and includes a substrate 19a, a rectifying portion 19b, a DCDC converter 19c, and the like. A capacitor 14c, a rectifier 19b, a DCDC converter 19c, and the like are mounted on the substrate 19a.

整流部１９ｂは、基板１９ａ上に実装された回路である。整流部１９ｂに２つある入力端の一方がコンデンサ１４ｃの上記他端に電気的に接続し、２つある入力端の他方がトランス１４ｂの出力側導線の他端に電気的に接続する。また、整流部１９ｂに２つある出力端がＤＣＤＣ変換器１９ｃに接続する。この整流部１９ｂは、受電側同調整合部１４から受けた電流を全波整流してＤＣＤＣ変換器１９ｃに出力する。   The rectifying unit 19b is a circuit mounted on the substrate 19a. One of the two input ends of the rectifier 19b is electrically connected to the other end of the capacitor 14c, and the other of the two input ends is electrically connected to the other end of the output-side conductor of the transformer 14b. Further, two output terminals of the rectifier 19b are connected to the DCDC converter 19c. The rectifying unit 19b performs full-wave rectification on the current received from the power receiving side tuning matching unit 14 and outputs the rectified current to the DCDC converter 19c.

ＤＣＤＣ変換器１９ｃは、基板１９ａ上に実装された回路であり、整流部１９ｂから印加された電圧を降圧して機能部２１に出力する。   The DCDC converter 19c is a circuit mounted on the substrate 19a, and steps down the voltage applied from the rectifying unit 19b and outputs it to the functional unit 21.

機能部２１は、半球形状の部材であり、主構造部材１３の後端にネジ２２ａ、２２ｂで固定される。この機能部２１は、給電時に、ＤＣＤＣ変換器１９ｃから電力が供給されると、その供給された電力を利用して作動する。機能部２１は、例えば、カメラであってもよいし、無線通信機であってもよい。   The functional unit 21 is a hemispherical member, and is fixed to the rear end of the main structural member 13 with screws 22a and 22b. When power is supplied from the DCDC converter 19c during power feeding, the functional unit 21 operates using the supplied power. The function unit 21 may be, for example, a camera or a wireless communication device.

非接触給電システムの構成は以上の通りである。次に、このような非接触給電システムにおける給電時の作動について説明する。なお、送電シート３は、給電を行う前に、既に壁２に固定されている。また、受電器１は、給電が行われる前は、壁２、送電シート３から離れた場所に置かれている。また、送電シート３は、給電が行われる前から、一方側送電電極３３ａ、他方側送電電極３３ｂは、それぞれ、給電線３１ａ、給電線３１ｂを介して、給電アダプタ５から高電圧かつ高周波の交流が供給され、その交流により、電界を発生している。   The configuration of the non-contact power feeding system is as described above. Next, the operation at the time of power feeding in such a non-contact power feeding system will be described. In addition, the power transmission sheet 3 is already fixed to the wall 2 before supplying power. In addition, the power receiver 1 is placed in a place away from the wall 2 and the power transmission sheet 3 before power feeding is performed. In addition, the power transmission sheet 3 has a high voltage and high frequency alternating current from the power supply adapter 5 through the power supply line 31a and the power supply line 31b, respectively, before the power supply is performed. Is supplied and an electric field is generated by the alternating current.

給電時には、作業者が、受電器１を持って、受電器１の受電シート１１が取り付けられている側を送電シート３に向ける。このとき、作業者は、一方側受電電極１１２ａと一方側送電電極３３ａが対向し、他方側受電電極１１２ｂと他方側送電電極３３ｂが平行に対向するよう、受電器１の位置および姿勢を調整する。この時点では、受電器１と送電シート３は接触していない。   At the time of power feeding, the operator holds the power receiver 1 and directs the power receiving sheet 11 side of the power receiver 1 to the power transmitting sheet 3. At this time, the operator adjusts the position and posture of the power receiver 1 so that the one-side power reception electrode 112a and the one-side power transmission electrode 33a face each other, and the other-side power reception electrode 112b and the other-side power transmission electrode 33b face each other in parallel. . At this time, the power receiver 1 and the power transmission sheet 3 are not in contact.

次に、作業者は、現在の姿勢のまま受電器１を送電シート３に近づけ、受電シート１１の絶縁材１１１を送電シート３の絶縁部材３０に接触させる。この結果、一方側受電電極１１２ａと一方側送電電極３３ａが、主構造部材１３を挟まず、絶縁材１１１と絶縁部材３０のみを挟んで近接した状態で平行に対向する。また、一方側受電電極１１２ａの前側端面と壁２とが、主構造部材１３を挟まず、送電シート３と空気のみを挟んだ状態で、壁２と対向する。また、他方側受電電極１１２ｂと他方側送電電極３３ｂが、絶縁材１１１と絶縁部材３０のみを挟んで近接した状態で平行に対向する。   Next, the worker brings the power receiver 1 close to the power transmission sheet 3 in the current posture, and brings the insulating material 111 of the power reception sheet 11 into contact with the insulating member 30 of the power transmission sheet 3. As a result, the one-side power receiving electrode 112a and the one-side power transmitting electrode 33a face each other in parallel in a state where the main structural member 13 is not sandwiched and only the insulating material 111 and the insulating member 30 are sandwiched. In addition, the front end face of the one-side power receiving electrode 112a and the wall 2 face the wall 2 without sandwiching the main structural member 13 and sandwiching only the power transmission sheet 3 and air. In addition, the other-side power receiving electrode 112b and the other-side power transmitting electrode 33b face each other in parallel in a state where only the insulating material 111 and the insulating member 30 are sandwiched therebetween.

このように近接した状態では、磁力により、第１磁石１２１ａと第２磁石１２１ｂが壁２に吸引される。その結果、受電器１全体が送電シート３に対して位置決めされ、作業者が受電シート１１から手を離しても、送電シート３に対する受電器１の位置は変化しなくなる。   In such a close state, the first magnet 121a and the second magnet 121b are attracted to the wall 2 by the magnetic force. As a result, the entire power receiver 1 is positioned with respect to the power transmission sheet 3, and the position of the power receiver 1 with respect to the power transmission sheet 3 does not change even if the operator releases the hand from the power reception sheet 11.

受電器１が送電シート３に対して位置決めされた状態においては、主構造部材１３は、第１磁界発生部１２ａ、第２磁界発生部１２ｂに支持された状態になる。またこのとき、受電シート１１、受電側同調整合部１４、内部プレート１５、ネジ１６ａ、ネジ１６ｂ、基板支柱１７ａ、基板支柱１７ｂ、ネジ１８ａ、ネジ１８ｂ、実装部１９、ネジ２０ａ、ネジ２０ｂ、機能部２１、ネジ２２ａ、ネジ２２ｂは、主構造部材１３に支持された状態になる。   In a state where the power receiver 1 is positioned with respect to the power transmission sheet 3, the main structural member 13 is supported by the first magnetic field generation unit 12a and the second magnetic field generation unit 12b. At this time, the power receiving sheet 11, the power receiving side tuning and matching portion 14, the internal plate 15, the screw 16a, the screw 16b, the board post 17a, the board post 17b, the screw 18a, the screw 18b, the mounting part 19, the screw 20a, the screw 20b, and the function The part 21, the screw 22a, and the screw 22b are supported by the main structural member 13.

このように、主構造部材１３は内部に収容する部材を支持するため、および、第１磁界発生部１２ａ、第２磁界発生部１２ｂに支持されるために、高い強度が要求される。その結果、主構造部材１３の厚みは、受電シート１１に比べて大きくなりがちである。   As described above, the main structural member 13 is required to have high strength in order to support the member housed therein and to be supported by the first magnetic field generation unit 12a and the second magnetic field generation unit 12b. As a result, the thickness of the main structural member 13 tends to be larger than that of the power receiving sheet 11.

受電器１が送電シート３に対して位置決めされると、一方側送電電極３３ａと一方側受電電極１１２ａが容量結合し、他方側送電電極３３ｂと他方側受電電極１１２ｂが容量結合する。これにより、一方側受電電極１１２ａおよび他方側受電電極１１２ｂが、それぞれ、一方側送電電極３３ａの電界および他方側送電電極３３ｂの電界を捕捉する。   When the power receiver 1 is positioned with respect to the power transmission sheet 3, the one side power transmission electrode 33a and the one side power reception electrode 112a are capacitively coupled, and the other side power transmission electrode 33b and the other side power reception electrode 112b are capacitively coupled. Thereby, the one side power reception electrode 112a and the other side power reception electrode 112b capture the electric field of the one side power transmission electrode 33a and the electric field of the other side power transmission electrode 33b, respectively.

そして、捕捉された電界に基づく交流が、受電側同調整合部１４を介して一方側受電電極１１２ａ、他方側受電電極１１２ｂから整流部１９ｂに供給され、整流部１９ｂがこの交流を直流に整流してＤＣＤＣ変換器１９ｃに供給する。そしてＤＣＤＣ変換器１９ｃが、整流部１９ｂから供給された直流を降圧して機能部２１に供給する。そして機能部２１は、整流部１９ｂから供給された直流を利用して作動する。   Then, alternating current based on the captured electric field is supplied to the rectifying unit 19b from the one side receiving electrode 112a and the other side receiving electrode 112b via the power receiving side tuning matching unit 14, and the rectifying unit 19b rectifies this alternating current into direct current. To the DCDC converter 19c. Then, the DCDC converter 19c steps down the direct current supplied from the rectifying unit 19b and supplies it to the functional unit 21. The functional unit 21 operates using the direct current supplied from the rectifying unit 19b.

以上説明した通り、第１磁石１２１ａ、第２磁石１２１ｂは、主構造部材１３の外側に配置されている。それにより、第１磁石１２１ａ、第２磁石１２１ｂは、一方側受電電極１１２ａ、他方側受電電極１１２ｂと一方側送電電極３３ａ、他方側送電電極３３ｂとがそれぞれ結合する際、壁２との間に主構造部材１３を挟まずに、壁２と対向可能となっている。   As described above, the first magnet 121 a and the second magnet 121 b are disposed outside the main structural member 13. Thereby, the first magnet 121a and the second magnet 121b are placed between the wall 2 when the one-side power receiving electrode 112a and the other-side power receiving electrode 112b are coupled to the one-side power transmitting electrode 33a and the other-side power transmitting electrode 33b, respectively. The main structural member 13 can be opposed to the wall 2 without sandwiching it.

このようになっていることで、受電側同調整合部１４等を支持するために比較的分厚い部材となっている主構造部材の分だけ、第１磁石１２１ａ、第２磁石１２１ｂと壁２の間隔を短縮し、第１磁石１２１ａ、第２磁石１２１ｂと壁２の吸引力をより強くすることができる。第１磁石１２１ａ、第２磁石１２１ｂと壁２の吸引力を強くすることができれば、受電器１の送電シート３からの脱落、位置ずれの可能性が低減される。   In this way, the distance between the first magnet 121a, the second magnet 121b, and the wall 2 is equivalent to the main structural member that is a relatively thick member for supporting the power receiving side tuning matching portion 14 and the like. And the attractive force of the first magnet 121a, the second magnet 121b and the wall 2 can be made stronger. If the attractive force of the first magnet 121a, the second magnet 121b, and the wall 2 can be increased, the possibility of the power receiver 1 falling off from the power transmission sheet 3 and being displaced is reduced.

また、一方側受電電極１１２ａ、他方側受電電極１１２ｂは、主構造部材１３の外側に配置されている。それにより、一方側受電電極１１２ａ、１１２ｂは、一方側送電電極３３ａ、他方側送電電極３３ｂとそれぞれ容量結合する際、一方側送電電極３３ａ、他方側送電電極３３ｂとの間に主構造部材１３を挟まずに一方側送電電極３３ａ、他方側送電電極３３ｂと対向可能となっている。   Further, the one side power receiving electrode 112 a and the other side power receiving electrode 112 b are arranged outside the main structural member 13. Thereby, when the one side power receiving electrodes 112a and 112b are capacitively coupled to the one side power transmitting electrode 33a and the other side power transmitting electrode 33b, respectively, the main structural member 13 is interposed between the one side power transmitting electrode 33a and the other side power transmitting electrode 33b. The first power transmission electrode 33a and the second power transmission electrode 33b can be opposed to each other without being sandwiched.

このように、一方側受電電極１１２ａ、他方側受電電極１１２ｂが主構造部材１３の外側に配置されており、それにより、一方側受電電極１１２ａ、他方側受電電極１１２ｂは、一方側送電電極３３ａ、他方側送電電極３３ｂと容量結合する際、送電素子との間に主構造部材を挟まずに送電素子と対向可能となっている。このようになっていることで、供給回路、１個以上の磁石等を支持するために比較的分厚い部材である主構造部材の分だけ、送電素子と受電素子の間隔を短縮し、容量結合を強くすることができる。   Thus, the one side power receiving electrode 112a and the other side power receiving electrode 112b are arranged outside the main structural member 13, whereby the one side power receiving electrode 112a and the other side power receiving electrode 112b are connected to the one side power transmitting electrode 33a, When capacitively coupling to the other power transmission electrode 33b, the main structural member can be opposed to the power transmission element without being sandwiched between the power transmission element. In this way, the distance between the power transmitting element and the power receiving element is shortened by the amount of the main structural member, which is a relatively thick member to support the supply circuit, one or more magnets, etc., and capacitive coupling is achieved. Can be strong.

また、一方側送電電極３３ａ、他方側送電電極３３ｂと一方側受電電極１１２ａ、他方側受電電極１１２ｂの結合は容量結合である。容量結合に用いられる電極は、電磁誘導に用いられるコイルに比べて薄く形成できるので、送電素子と受電素子の距離を縮めることによる効果がより顕著に表れる。   Moreover, the coupling | bonding of the one side power transmission electrode 33a, the other side power transmission electrode 33b, the one side power reception electrode 112a, and the other side power reception electrode 112b is capacitive coupling. Since the electrode used for capacitive coupling can be formed thinner than the coil used for electromagnetic induction, the effect of reducing the distance between the power transmitting element and the power receiving element appears more significantly.

また、主構造部材１３は、一方側送電電極３３ａ、他方側送電電極３３ｂと対向する側において、一方側送電電極３３ａ、他方側送電電極３３ｂとは反対の側に窪む第１窪部１３２ａ、第２窪部１３２ｂを有している。また、第１磁石１２１ａ、第２磁石１２１ｂは、一方側受電電極１１２ａ、他方側受電電極１１２ｂは、それぞれ、第１窪部１３２ａ、第２窪部１３２ｂに収容される。また、一方側受電電極１１２ａ、他方側受電電極１１２ｂは、第１磁石１２１ａ、第２磁石１２１ｂの一方側送電電極３３ａ、他方側送電電極３３ｂ側の端部よりも、一方側送電電極３３ａ、他方側送電電極３３ｂ側に突出している。   The main structural member 13 includes a first recess 132a that is recessed on the side opposite to the one side power transmission electrode 33a and the other side power transmission electrode 33b on the side facing the one side power transmission electrode 33a and the other side power transmission electrode 33b. It has the 2nd hollow part 132b. In addition, the first magnet 121a and the second magnet 121b are housed in the first recess 132a and the second recess 132b, respectively, on the one side receiving electrode 112a and the other side receiving electrode 112b. In addition, the one side power receiving electrode 112a and the other side power receiving electrode 112b are arranged on the one side power transmitting electrode 33a and the other side of the first magnet 121a and the second magnet 121b on the one side power transmitting electrode 33a and the other side power transmitting electrode 33b side. It protrudes to the side power transmission electrode 33b side.

仮に第１磁石１２１ａ、第２磁石１２１ｂの一方側送電電極３３ａ、他方側送電電極３３ｂ側の端部が一方側受電電極１１２ａ、他方側受電電極１１２ｂよりも突出していれば、その突出分だけ、一方側送電電極３３ａ、他方側送電電極３３ｂと一方側受電電極１１２ａ、他方側受電電極１１２ｂの間の距離が長くなってしまう可能性がある。したがって、上記のように、一方側受電電極１１２ａ、他方側受電電極１１２ｂは、第１磁石１２１ａ、第２磁石１２１ｂの一方側送電電極３３ａ、他方側送電電極３３ｂ側の端部よりも、一方側送電電極３３ａ、他方側送電電極３３ｂ側に突出しているようにすれば、一方側送電電極３３ａ、他方側送電電極３３ｂと一方側受電電極１１２ａ、他方側受電電極１１２ｂの間に無駄な空間ができることを防ぐことができ、送電距離を短くすることができる。   If the first power transmission electrode 33a and the second power transmission electrode 33b end of the first magnet 121a and the second magnet 121b protrude from the first power reception electrode 112a and the other power reception electrode 112b, only the amount of the protrusion There is a possibility that the distances between the one-side power transmission electrode 33a and the other-side power transmission electrode 33b and the one-side power reception electrode 112a and the other-side power reception electrode 112b become long. Therefore, as described above, the one-side power reception electrode 112a and the other-side power reception electrode 112b are on one side of the first magnet 121a and the one-side power transmission electrode 33a and the other-side power transmission electrode 33b side ends of the second magnet 121b. By projecting toward the power transmitting electrode 33a and the other power transmitting electrode 33b, there is a useless space between the one power transmitting electrode 33a and the other power transmitting electrode 33b and the one power receiving electrode 112a and the other power receiving electrode 112b. Can be prevented, and the transmission distance can be shortened.

また、第１磁石１２１ａ、第２磁石１２１ｂの各々を覆う樹脂部材である第１樹脂カバー１２２ａ、第２樹脂カバー１２２ｂが設けられている。また、これら第１樹脂カバー１２２ａ、第２樹脂カバー１２２ｂの各々を覆う磁性体である第１磁性体カバー１２３ａ、第２磁性体カバー１２３ｂが設けられている。   Moreover, the 1st resin cover 122a and the 2nd resin cover 122b which are the resin members which cover each of the 1st magnet 121a and the 2nd magnet 121b are provided. A first magnetic body cover 123a and a second magnetic body cover 123b, which are magnetic bodies that cover the first resin cover 122a and the second resin cover 122b, are provided.

そして、これら第１樹脂カバー１２２ａおよび第１磁性体カバー１２３ａは、第１磁石１２１ａと主構造部材１３の間に介在する。また、第２樹脂カバー１２２ｂおよび第２磁性体カバー１２３ｂは、第２磁石１２１ｂと主構造部材１３の間に介在する。   The first resin cover 122 a and the first magnetic body cover 123 a are interposed between the first magnet 121 a and the main structural member 13. The second resin cover 122 b and the second magnetic body cover 123 b are interposed between the second magnet 121 b and the main structural member 13.

このようになっていることで、第１磁石１２１ａ、第２磁石１２１ｂから主構造部材１３の内部への磁界の漏洩を抑えることができる。ひいては、第１磁石１２１ａ、第２磁石１２１ｂとコイル１４ａ、トランス１４ｂを含む他の部品との電磁的干渉を防ぐことができる。   In this way, leakage of the magnetic field from the first magnet 121a and the second magnet 121b to the inside of the main structural member 13 can be suppressed. As a result, the electromagnetic interference with the 1st magnet 121a, the 2nd magnet 121b, and other components including the coil 14a and the transformer 14b can be prevented.

また、第１磁石１２１ａ、第２磁石１２１ｂ磁石は、所定の中心軸１０を基準として２回対称になっているこのようになっていることで、送電シート３に位置決めされた受電器１にかかる重力のバランスが良好になり易く、安定した位置決め、ひいては安定した受電が可能になる。   In addition, the first magnet 121a and the second magnet 121b magnets are symmetrical twice with respect to the predetermined central axis 10, and thus are applied to the power receiver 1 positioned on the power transmission sheet 3. Gravity balance is likely to be good, and stable positioning and, in turn, stable power reception become possible.

また、受電側同調整合部１４と一方側受電電極１１２ａ、他方側受電電極１１２ｂを繋ぐ給電線４１、４２は、主構造部材１３の内部において、受電側同調整合部１４から伸び、主構造部材１３に形成された孔を通って主構造部材１３の外部に出て、一方側受電電極１１２ａ、他方側受電電極１１２ｂに接続される。   In addition, the power supply lines 41 and 42 that connect the power receiving side tuning matching portion 14 to the one side power receiving electrode 112 a and the other side power receiving electrode 112 b extend from the power receiving side tuning matching portion 14 inside the main structural member 13. It passes through the hole formed in the outer surface of the main structural member 13 and is connected to the first power receiving electrode 112a and the second power receiving electrode 112b.

このようになっていることで、基板や給電線４１の曲げが不要なので、給電線４１が長寿命化する。また、供給回路１４、１９ｂ、１９ｃから一方側受電電極１１２ａ、他方側受電電極１１２ｂまでの線路長さが短くなるので、給電線４１、４２に加わる外乱によって一方側受電電極１１２ａ、他方側受電電極１１２ｂの電気的特性が劣化する可能性が低減される。   In this way, since bending of the substrate and the power supply line 41 is unnecessary, the life of the power supply line 41 is extended. Further, since the line length from the supply circuits 14, 19b, 19c to the one-side power receiving electrode 112a and the other-side power receiving electrode 112b is shortened, the one-side power receiving electrode 112a, the other-side power receiving electrode due to disturbance applied to the feeder lines 41, 42 The possibility of deterioration of the electrical characteristics of 112b is reduced.

（第２実施形態）
次に第２実施形態について説明する。本実施形態の非接触給電システムは、第１実施形態の非接触給電システムに対して、壁２を壁４および磁石シート６ａ、６ｂ、６ｃに置き換えたものである。 (Second Embodiment)
Next, a second embodiment will be described. The contactless power supply system of the present embodiment is obtained by replacing the wall 2 with a wall 4 and magnet sheets 6a, 6b, and 6c with respect to the contactless power supply system of the first embodiment.

壁４は、第１実施形態の壁２に対して、その材質を変更したものである。壁４は、鉄でも他の磁性体でもなく、例えば木製であってもよいし、モルタル製であってもよいし、樹脂製であってもよい。   The wall 4 is obtained by changing the material of the wall 2 of the first embodiment. The wall 4 is not made of iron or other magnetic material, and may be made of, for example, wooden, made of mortar, or made of resin.

この場合、受電器１の第１磁石１２１ａ、第１樹脂カバー１２２ａは、磁力によって壁２に吸引されることはない。そこで、本実施形態は、送電シート３の壁４側の面に、磁石シート６ａ、６ｂ、６ｃを貼り付け、更に、送電シート３と磁石シート６ａ、６ｂ、６ｃを壁４に貼り付ける。   In this case, the first magnet 121a and the first resin cover 122a of the power receiver 1 are not attracted to the wall 2 by the magnetic force. Therefore, in the present embodiment, the magnet sheets 6a, 6b, and 6c are attached to the wall 4 side surface of the power transmission sheet 3, and the power transmission sheet 3 and the magnet sheets 6a, 6b, and 6c are further attached to the wall 4.

磁石シート６ａ、６ｂ、６ｃの各々は、シート形状の永久磁石であり、一方側の面が送電シート３に貼り付けられ、他方側の面が壁４に貼り付けられる。送電シート３に近づけられた第１磁石１２１ａ、第２磁石１２１ｂと互いに吸引し合うような配置で、送電シート３、壁４に取り付けられる。   Each of the magnet sheets 6 a, 6 b, and 6 c is a sheet-shaped permanent magnet, and one surface is affixed to the power transmission sheet 3 and the other surface is affixed to the wall 4. The first magnet 121a and the second magnet 121b that are brought close to the power transmission sheet 3 are attached to the power transmission sheet 3 and the wall 4 so as to attract each other.

このようにすることで、壁４が磁性体でなくても、第１磁石１２１ａ、第２樹脂カバー１２２ｂが磁石シート６ａ、６ｂ、６ｃのいずれかに吸引されることで、受電器１の位置決めが可能になる。なお、磁石シート６ａ、６ｂ、６ｃは、磁石シートは給電シートと一体化していてもよい。   By doing in this way, even if the wall 4 is not a magnetic body, the first magnet 121a and the second resin cover 122b are attracted to one of the magnet sheets 6a, 6b, and 6c, thereby positioning the power receiver 1. Is possible. The magnet sheets 6a, 6b, 6c may be integrated with the power supply sheet.
