本実施形態の非接触給電システムA1は、図1に示すように、蓄電池320(図9参照)の電力を用いて移動可能な電動移動体3に対して非接触で給電するために用いられる。 As shown in FIG. 1, the non-contact power supply system A1 of the present embodiment is used to non-contactly supply power to the movable electric moving body 3 using the electric power of the storage battery 320 (see FIG. 9).

非接触給電システムA1は、受電部20と、非接触給電装置1と、を備える。受電部20は、蓄電池320の電力を用いて移動可能な電動移動体3に設けられる。非接触給電装置1は、駐車中の電動移動体3の蓄電池320に、非接触給電トランスTR1を用いて給電する。非接触給電装置1は、非接触給電トランスTR1の送電部10を有する。送電部10及び受電部20の少なくとも一方は、電動移動体3の駐車中に送電部10と受電部20とが対向する対向方向(矢印DR1又はDR2の方向)において移動可能である。非接触給電システムA1は保持部(コイルばね90)を更に備える。保持部(コイルばね90)は、電動移動体3の駐車中に、送電部10において受電部20と対向する第1面12と、受電部20において送電部10と対向する第2面22とが互いに押し付けられた状態を保持する。 The non-contact power feeding system A1 includes a power receiving unit 20 and a non-contact power feeding device 1. The power receiving unit 20 is provided on the electric moving body 3 that can be moved by using the electric power of the storage battery 320. The non-contact power feeding device 1 supplies power to the storage battery 320 of the parked electric moving body 3 by using the non-contact power feeding transformer TR1. The non-contact power feeding device 1 has a power transmission unit 10 of the non-contact power feeding transformer TR1. At least one of the power transmission unit 10 and the power reception unit 20 can move in the opposite direction (direction of arrow DR1 or DR2) in which the power transmission unit 10 and the power reception unit 20 face each other while the electric moving body 3 is parked. The non-contact power feeding system A1 further includes a holding portion (coil spring 90). The holding unit (coil spring 90) has a first surface 12 facing the power receiving unit 20 in the power transmitting unit 10 and a second surface 22 facing the power transmitting unit 10 in the power receiving unit 20 while the electric moving body 3 is parked. Hold the state of being pressed against each other.

本実施形態では、非接触給電システムA1が給電する対象の電動移動体3は、例えば電動自転車である。なお、電動移動体3は、電動自転車に限定されず、電動モータ付きのキックボード、電動モータ付きの三輪車、電動車椅子、3輪又は4輪の小型モビリティ、又は電動自動車等でもよい。以下の実施形態では電動移動体3が電動自転車である場合について説明する。 In the present embodiment, the electric moving body 3 to be fed by the non-contact power feeding system A1 is, for example, an electric bicycle. The electric moving body 3 is not limited to an electric bicycle, and may be a kickboard with an electric motor, a tricycle with an electric motor, an electric wheelchair, a small mobility of three or four wheels, an electric vehicle, or the like. In the following embodiment, a case where the electric moving body 3 is an electric bicycle will be described.

ここにおいて、「非接触で給電」するとは、送電部10と受電部20との間が電線等を介して物理的に接続されていない状態で給電することをいう。したがって、非接触で給電するとは、送電部10の第1面12と受電部20の第2面22とが互いに接触しているが、送電部10と受電部20とが互いに連結されていない状態で給電することを含み得る。 Here, "non-contact power supply" means that power is supplied in a state where the power transmission unit 10 and the power reception unit 20 are not physically connected via an electric wire or the like. Therefore, non-contact power supply means that the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception unit 20 are in contact with each other, but the power transmission unit 10 and the power reception unit 20 are not connected to each other. May include powering with.

本実施形態の非接触給電システムA1では、保持部(コイルばね90)が、第1面12と第2面22とが互いに押し付けられた状態を保持しているので、送電部10と受電部20との相対的な位置がずれにくくなる。したがって、送電部10と受電部20との相対的な位置がずれることで、送電部10と受電部20との間での電力の伝達効率が低下する可能性を低減でき、電力の伝達効率の低下を抑制可能な非接触給電システムA1を提供することができる。 In the non-contact power feeding system A1 of the present embodiment, the holding unit (coil spring 90) holds the state in which the first surface 12 and the second surface 22 are pressed against each other, so that the power transmitting unit 10 and the power receiving unit 20 are held. The relative position with and is less likely to shift. Therefore, it is possible to reduce the possibility that the power transmission efficiency between the power transmission unit 10 and the power reception unit 20 is lowered due to the relative position of the power transmission unit 10 and the power reception unit 20, and the power transmission efficiency can be reduced. It is possible to provide a non-contact power transmission system A1 capable of suppressing a decrease.

本実施形態の非接触給電システムA1は電動移動体3を更に備える。非接触給電システムA1は上述の保持部(コイルばね90)を備えているので、電力の伝達効率の低下を抑制可能な非接触給電システムA1を提供することができる。 The non-contact power feeding system A1 of the present embodiment further includes an electric mobile body 3. Since the non-contact power feeding system A1 includes the above-mentioned holding portion (coil spring 90), it is possible to provide the non-contact power feeding system A1 capable of suppressing a decrease in power transmission efficiency.

In the following description, the X-axis direction in FIGS. 1 and 3 to 5 is defined as the left-right direction, the Y-axis direction is defined as the front-rear direction (depth direction), and the Z-axis direction is defined as the vertical direction. Further, the positive direction in the X-axis direction is defined as the right side, the positive direction in the Y-axis direction is defined as the front side, and the positive direction in the Z-axis direction is defined as the upper side. However, these directions are examples, and are not intended to limit the directions when the non-contact power supply system A1 is used. In addition, the arrows indicating each direction in the drawing are shown only for the sake of explanation, and are not accompanied by an entity.

非接触給電システムA1は、送電部10を有する非接触給電装置1と、受電部20を有する非接触受電装置2とを備える。本実施形態では、非接触受電装置2は取付部材4を用いて電動移動体3に取り付けられている。非接触給電装置1は、電動移動体3の駐車時に、非接触受電装置2に対して電力を供給し、非接触受電装置2を介して電動移動体3の蓄電池320を充電するために使用される。以下、電動移動体3、非接触受電装置2、取付部材4及び非接触給電装置1についてそれぞれ説明する。 The non-contact power supply system A1 includes a non-contact power supply device 1 having a power transmission unit 10 and a non-contact power reception device 2 having a power reception unit 20. In the present embodiment, the non-contact power receiving device 2 is attached to the electric moving body 3 by using the attachment member 4. The non-contact power feeding device 1 is used to supply electric power to the non-contact power receiving device 2 when the electric moving body 3 is parked, and to charge the storage battery 320 of the electric moving body 3 via the non-contact power receiving device 2. To. Hereinafter, the electric mobile body 3, the non-contact power receiving device 2, the mounting member 4, and the non-contact power feeding device 1 will be described.

(2.1)電動移動体
電動移動体3は、例えば、電動機で人力を補助する電動アシスト自転車である。なお、電動移動体3は、電動機のみで走行可能な電動自転車でもよい。
(2.1) Electric Mobile Body The electric mobile body 3 is, for example, an electrically assisted bicycle that assists human power with an electric motor. The electric moving body 3 may be an electric bicycle that can travel only with an electric motor.

電動移動体3は、図9に示すように、蓄電池320と、蓄電池320を充電する充電回路321とを有する。また、電動移動体3は、車輪(例えば後輪)に回転力を加える電動機と、蓄電池320に蓄えられた電力で電動機を回転させる制御回路とを備える。この制御回路は、例えば人がペダルを踏む力をセンサ等で検出し、センサの検出結果に基づいて電動機の回転力を制御する。 As shown in FIG. 9, the electric mobile body 3 has a storage battery 320 and a charging circuit 321 for charging the storage battery 320. Further, the electric moving body 3 includes an electric motor that applies a rotational force to wheels (for example, rear wheels) and a control circuit that rotates the electric motor with the electric power stored in the storage battery 320. This control circuit detects, for example, the force with which a person steps on a pedal with a sensor or the like, and controls the rotational force of the electric motor based on the detection result of the sensor.

電動移動体3の車体301は、図9及び図10に示すように、車輪(例えば前輪310)の車軸311を保持する二股のフォーク部(フロントフォーク)302を備えている。ここで、フォーク部302を含む車体301の一部に受電部20を取り付けるための取付部材4と、車軸311とがフォーク部302に共締めされている。これにより、電動移動体3において前輪310の車軸311をフォーク部302に固定するための構成を利用して受電部20を車体301に取り付けることができるので、簡易な構成で受電部20を電動移動体3に取り付けることができる。なお、取付部材4については、「(2.3)取付部材」の欄で詳しく説明する。 As shown in FIGS. 9 and 10, the vehicle body 301 of the electric moving body 3 includes a bifurcated fork portion (front fork) 302 that holds the axle 311 of the wheel (for example, the front wheel 310). Here, the mounting member 4 for mounting the power receiving portion 20 to a part of the vehicle body 301 including the fork portion 302 and the axle 311 are fastened together to the fork portion 302. As a result, the power receiving unit 20 can be attached to the vehicle body 301 by using the configuration for fixing the axle 311 of the front wheel 310 to the fork portion 302 in the electric moving body 3, so that the power receiving unit 20 can be electrically moved with a simple configuration. It can be attached to the body 3. The mounting member 4 will be described in detail in the column of "(2.3) Mounting member".

(2.2)非接触受電装置
非接触受電装置2は、図1、図9及び図10に示すように、受電部20と、受電部20を保持するベース部材27と、を備えている。非接触受電装置2の受電部20は、電動移動体3が備える車輪に対して固定された位置に配置されており、本実施形態では受電部20は前輪310に対して固定された位置に配置されている。さらに言えば、受電部20は、電動移動体3が備える車輪(例えば前輪310)の車軸311の延長線L1上に配置されるように、電動移動体3の車体301(例えばフォーク部302)に取り付けられている。したがって、送電部10及び受電部20は、車輪(前輪310)の車軸311の延長線L1上で対向している。電動移動体3の車輪(前輪310)の寸法及び形状は走行性能に大きく影響するため、一般的に高い寸法精度が要求されている。本実施形態では、受電部20が車輪(前輪310)に対して固定された位置であって、例えば車軸311の延長線L1上に配置されているので、車体301において受電部20の位置のずれが抑制される。したがって、送電部10と受電部20との相対的な位置ずれを低減でき、送電部10と受電部20との間での電力の伝達効率の低下を抑制できる。また、電動移動体3では、保持部(コイルばね90)による押し付け力を車軸311及びその周辺で受けることができるので、電動移動体3において保持部(コイルばね90)による押し付け力を受ける部位の強度を高めやすいという利点がある。
(2.2) Non-contact power receiving device As shown in FIGS. 1, 9 and 10, the non-contact power receiving device 2 includes a power receiving unit 20 and a base member 27 holding the power receiving unit 20. The power receiving unit 20 of the non-contact power receiving device 2 is arranged at a position fixed to the wheel included in the electric moving body 3, and in the present embodiment, the power receiving unit 20 is arranged at a position fixed to the front wheel 310. Has been done. Further, the power receiving unit 20 is arranged on the vehicle body 301 (for example, fork portion 302) of the electric moving body 3 so as to be arranged on the extension line L1 of the axle 311 of the wheel (for example, the front wheel 310) included in the electric moving body 3. It is attached. Therefore, the power transmission unit 10 and the power reception unit 20 face each other on the extension line L1 of the axle 311 of the wheel (front wheel 310). Since the dimensions and shape of the wheels (front wheels 310) of the electric moving body 3 have a great influence on the running performance, high dimensional accuracy is generally required. In the present embodiment, since the power receiving unit 20 is at a fixed position with respect to the wheels (front wheels 310) and is arranged on, for example, the extension line L1 of the axle 311, the position of the power receiving unit 20 is displaced in the vehicle body 301. Is suppressed. Therefore, the relative misalignment between the power transmission unit 10 and the power reception unit 20 can be reduced, and the decrease in power transmission efficiency between the power transmission unit 10 and the power reception unit 20 can be suppressed. Further, in the electric moving body 3, since the pressing force by the holding portion (coil spring 90) can be received in the axle 311 and its surroundings, the portion of the electric moving body 3 that receives the pressing force by the holding portion (coil spring 90). It has the advantage that it is easy to increase the strength.

受電部20は、受電コイルを有する受電モジュール21と、受電モジュール21の側面を少なくとも覆う受電側カバー23とを備える。 The power receiving unit 20 includes a power receiving module 21 having a power receiving coil and a power receiving side cover 23 that at least covers the side surface of the power receiving module 21.

受電モジュール21は、例えばスパイラルコイルのような受電コイルと、受電用電源回路とを合成樹脂製のケース内に収容して構成される。受電モジュール21は、送電部10と対向する第2面22を有している。第2面22の平面視の形状は略円形である。送電部10と受電部20との間では例えば電磁誘導方式で非接触給電が行われる。送電部10の第1面12と受電モジュール21の第2面22とが対向した状態で、送電部10の送電コイルに高周波の電流が流れると、送電コイルと受電コイルとの間に誘導磁束が発生し、受電コイルに所定周波数の高周波電流が流れる。受電モジュール21の受電用電源回路は、受電コイルに流れる電流を整流、平滑することで、所定の電圧値(例えばDC24V)の直流電圧を発生する。受電モジュール21は電線29を介して充電回路321に接続されており、充電回路321は受電モジュール21から直流電力の供給を受けて蓄電池320を充電する。なお、非接触給電システムA1が採用する非接触給電方式は、電磁誘導方式に限定されず、磁気共鳴方式、電界結合方式、又は直流共鳴方式等の非接触給電方式でもよい。 The power receiving module 21 is configured by accommodating a power receiving coil such as a spiral coil and a power receiving power supply circuit in a synthetic resin case. The power receiving module 21 has a second surface 22 facing the power transmission unit 10. The shape of the second surface 22 in a plan view is substantially circular. Non-contact power supply is performed between the power transmission unit 10 and the power reception unit 20 by, for example, an electromagnetic induction method. When a high-frequency current flows through the transmission coil of the power transmission unit 10 while the first surface 12 of the power transmission unit 10 and the second surface 22 of the power reception module 21 face each other, an induced magnetic flux is generated between the power transmission coil and the power reception coil. It is generated and a high frequency current of a predetermined frequency flows through the power receiving coil. The power receiving power supply circuit of the power receiving module 21 generates a DC voltage having a predetermined voltage value (for example, DC24V) by rectifying and smoothing the current flowing through the power receiving coil. The power receiving module 21 is connected to the charging circuit 321 via the electric wire 29, and the charging circuit 321 receives the supply of DC power from the power receiving module 21 to charge the storage battery 320. The non-contact power feeding method adopted by the non-contact power feeding system A1 is not limited to the electromagnetic induction method, and may be a non-contact power feeding method such as a magnetic resonance method, an electric field coupling method, or a DC resonance method.

ベース部材27は円板状の金属板を有している。ベース部材27の一面には、受電モジュール21が例えばねじ又はスナップフィット等の適宜の方法で取り付けられている。また、ベース部材27の一面には、受電モジュール21を覆うようにして、受電側カバー23がねじ又はスナップフィット等の適宜の方法で取り付けられている。 The base member 27 has a disc-shaped metal plate. A power receiving module 21 is attached to one surface of the base member 27 by an appropriate method such as a screw or a snap fit. Further, a power receiving side cover 23 is attached to one surface of the base member 27 by an appropriate method such as a screw or a snap fit so as to cover the power receiving module 21.

受電側カバー23は、円環状の前壁24と、前壁24の外周縁から送電部10と反対側に突出する周壁26とを備えている。前壁24の中央には、受電モジュール21の第2面22を露出させる円形の窓孔25が設けられている。前壁24の表面は、外側に行くほど送電部10から離れる向きに傾斜する傾斜面24Aとなっている。 The power receiving side cover 23 includes an annular front wall 24 and a peripheral wall 26 projecting from the outer peripheral edge of the front wall 24 to the opposite side of the power transmission unit 10. In the center of the front wall 24, a circular window hole 25 for exposing the second surface 22 of the power receiving module 21 is provided. The surface of the front wall 24 is an inclined surface 24A that inclines toward the outside toward the power transmission unit 10.

ここにおいて、窓孔25から露出する第2面22と、受電側カバー23とで、受電コイルを覆う第2カバー部28(図9及び図10参照)が構成される。つまり、受電部20は、受電コイルと、第2面22を含んで受電コイルを覆う第2カバー部28とを有している。なお、本実施形態では第2面22と、受電側カバー23とが別体であるが、第2面22を有する受電モジュール21と受電側カバー23とが一体の部品(第2カバー部28)として形成されてもよい。また、受電側カバー23が、受電モジュール21におけるベース部材27と反対側の面を覆ってもよく、この場合は受電側カバー23の表面が第2面22となる。 Here, the second surface 22 exposed from the window hole 25 and the power receiving side cover 23 form a second cover portion 28 (see FIGS. 9 and 10) that covers the power receiving coil. That is, the power receiving unit 20 has a power receiving coil and a second cover portion 28 including the second surface 22 and covering the power receiving coil. In the present embodiment, the second surface 22 and the power receiving side cover 23 are separate bodies, but the power receiving module 21 having the second surface 22 and the power receiving side cover 23 are integrated parts (second cover portion 28). May be formed as. Further, the power receiving side cover 23 may cover the surface of the power receiving module 21 opposite to the base member 27, and in this case, the surface of the power receiving side cover 23 becomes the second surface 22.

(2.3)取付部材
取付部材4は、電動移動体3の前輪310を保持するフォーク部302に非接触受電装置2を取り付けるために用いられる。
(2.3) Mounting member The mounting member 4 is used to mount the non-contact power receiving device 2 on the fork portion 302 that holds the front wheel 310 of the electric moving body 3.

取付部材4は、図10に示すように、前輪310の車軸311を挿入するための貫通孔42が設けられた矩形板状のベース部41を有している。ベース部41の3辺には受電部20が取り付けられる受電部取付部43がそれぞれ設けられ、ベース部41の残りの1辺からは延伸部44が延びている。つまり、取付部材4は、車輪(例えば前輪310)の車軸311を挿入するための貫通孔42を有するベース部41と、ベース部41の周縁部に設けられて受電部20が取り付けられる受電部取付部43と、を有している。受電部20は取付部材4を用いて電動移動体3の車体301に取り付けられるので、車軸311をフォーク部302に固定するための構成を利用して受電部20を車体301に取り付けることができる。 As shown in FIG. 10, the mounting member 4 has a rectangular plate-shaped base portion 41 provided with a through hole 42 for inserting the axle 311 of the front wheel 310. A power receiving portion mounting portion 43 to which the power receiving portion 20 is attached is provided on each of the three sides of the base portion 41, and an extending portion 44 extends from the remaining one side of the base portion 41. That is, the mounting member 4 is mounted on a base portion 41 having a through hole 42 for inserting the axle 311 of the wheel (for example, the front wheel 310) and a power receiving portion mounted on the peripheral portion of the base portion 41 to which the power receiving portion 20 is mounted. It has a part 43 and. Since the power receiving unit 20 is attached to the vehicle body 301 of the electric moving body 3 by using the mounting member 4, the power receiving unit 20 can be attached to the vehicle body 301 by using the configuration for fixing the axle 311 to the fork portion 302.

受電部取付部43は側面視の形状がL形に形成されており、受電部取付部43において受電部20が固定される部位は、ベース部41に対して、車輪(前輪310)と反対側に位置をずらして配置されている。つまり、受電部取付部43は、ベース部41に対して車輪(前輪310)と反対側に配置されており、受電部20は、ベース部41に対して車輪(前輪310)と反対側で、受電部取付部43に取り付けられている。すなわち、受電部取付部43において受電部20が固定される部位と、ベース部41との間には、車軸311の軸方向において間隔が開けられており、受電部取付部43に固定される受電部20は、ベース部41に対して車輪(前輪310)と反対側に配置されている。これにより、受電部取付部43に取り付けられる受電部20とベース部41との間に間隔を開けた状態で受電部20を配置することができる。したがって、受電部取付部43に取り付けられる受電部20とベース部41との間に、取付部材4と車軸311とをフォーク部302に共締めするための部材(例えばナット46)を配置することができる。 The power receiving portion mounting portion 43 has an L-shaped side view, and the portion of the power receiving portion mounting portion 43 to which the power receiving portion 20 is fixed is on the side opposite to the wheel (front wheel 310) with respect to the base portion 41. The wheels are staggered. That is, the power receiving portion mounting portion 43 is arranged on the side opposite to the wheel (front wheel 310) with respect to the base portion 41, and the power receiving portion 20 is located on the side opposite to the wheel (front wheel 310) with respect to the base portion 41. It is attached to the power receiving unit attachment portion 43. That is, there is a gap in the axial direction of the axle 311 between the portion of the power receiving portion mounting portion 43 to which the power receiving portion 20 is fixed and the base portion 41, and the power receiving portion is fixed to the power receiving portion mounting portion 43. The portion 20 is arranged on the side opposite to the wheel (front wheel 310) with respect to the base portion 41. As a result, the power receiving unit 20 can be arranged with a gap between the power receiving unit 20 attached to the power receiving unit mounting unit 43 and the base unit 41. Therefore, a member (for example, a nut 46) for fastening the mounting member 4 and the axle 311 to the fork portion 302 can be arranged between the power receiving portion 20 attached to the power receiving portion mounting portion 43 and the base portion 41. it can.

ここで、延伸部44は、車軸311の軸方向(図9及び図10の線L1と平行な方向)と交差する方向に延びており、この延伸部44がフォーク部302に固定される。本実施形態では延伸部44はフォーク部302に沿って延びている。延伸部44には固定用のねじ48を挿入するための貫通孔45が延出方向に沿って複数設けられている。なお、延伸部44に複数の貫通孔45が設けられることは必須ではなく、少なくとも1つの貫通孔45が設けられていればよい。 Here, the extending portion 44 extends in a direction intersecting the axial direction of the axle 311 (direction parallel to the line L1 in FIGS. 9 and 10), and the extending portion 44 is fixed to the fork portion 302. In the present embodiment, the extending portion 44 extends along the fork portion 302. The stretched portion 44 is provided with a plurality of through holes 45 for inserting the fixing screws 48 along the extending direction. It is not essential that the stretched portion 44 is provided with a plurality of through holes 45, and at least one through hole 45 may be provided.

この取付部材4と前輪310の車軸311とはフォーク部302の先端部分に共締めされる。取付部材4をフォーク部302に取り付ける際には、まずフォーク部302の先端部分の溝に車軸311を通し、この車軸311にベース部41の貫通孔42とワッシャ47とを通す。そして、車軸311の先端部分のねじ部にナット46をねじ込むことによって、車軸311と取付部材4とをフォーク部302の先端部分である第1部位304(図10参照)に共締めする。 The mounting member 4 and the axle 311 of the front wheel 310 are fastened together with the tip of the fork portion 302. When attaching the mounting member 4 to the fork portion 302, first, the axle 311 is passed through the groove at the tip of the fork portion 302, and the through hole 42 of the base portion 41 and the washer 47 are passed through the axle 311. Then, by screwing the nut 46 into the threaded portion of the tip portion of the axle 311, the axle 311 and the mounting member 4 are fastened together with the first portion 304 (see FIG. 10) which is the tip portion of the fork portion 302.

そして、フォーク部302に設けられた固定片303のねじ孔と、延伸部44の貫通孔45とを位置合わせした後、ねじ48のねじ部をワッシャ49と貫通孔45とに通して固定片303のねじ孔にねじ込むことで、延伸部44をフォーク部302に固定する。つまり、フォーク部302の先端側の第1部位304で車軸311と取付部材4とが共締めされるとともに、取付部材4は、フォーク部302において第1部位304以外の第2部位305で更に固定されている。取付部材4は、フォーク部302において第1部位304以外の第2部位305でも固定されているので、取付部材4のベース部41が車軸311の周りに回転しにくくなる。ベース部41が車軸311の周りに回転すると、ナット46が緩みやすくなるが、本実施形態では取付部材4を第2部位305でも固定することで、取付部材4が回転しにくくなる。したがって、車軸311を固定するナット46が緩みにくくなり、車軸311の固定状態が緩む可能性を低減できる。 Then, after aligning the screw hole of the fixing piece 303 provided in the fork portion 302 with the through hole 45 of the extending portion 44, the screw portion of the screw 48 is passed through the washer 49 and the through hole 45 to fix the fixing piece 303. The extension portion 44 is fixed to the fork portion 302 by screwing into the screw hole of. That is, the axle 311 and the mounting member 4 are jointly tightened at the first portion 304 on the tip end side of the fork portion 302, and the mounting member 4 is further fixed at the fork portion 302 at the second portion 305 other than the first portion 304. Has been done. Since the mounting member 4 is also fixed to the second portion 305 other than the first portion 304 in the fork portion 302, the base portion 41 of the mounting member 4 is less likely to rotate around the axle 311. When the base portion 41 rotates around the axle 311, the nut 46 tends to loosen, but in the present embodiment, by fixing the mounting member 4 also at the second portion 305, the mounting member 4 becomes difficult to rotate. Therefore, the nut 46 for fixing the axle 311 is less likely to loosen, and the possibility that the fixed state of the axle 311 will loosen can be reduced.

次に、取付部材4がフォーク部302に固定された状態で、各受電部取付部43の貫通孔に通した固定ねじ431(図1参照)を、受電部20のベース部材27のねじ孔にねじ込むことによって、受電部20が取付部材4に固定される。これにより、受電部20が取付部材4を介して電動移動体3のフォーク部302に取り付けられており、受電部20は、電動移動体3が備える車輪(前輪310)の車軸311の延長線上に配置されている。 Next, with the mounting member 4 fixed to the fork portion 302, the fixing screw 431 (see FIG. 1) passed through the through hole of each power receiving portion mounting portion 43 is inserted into the screw hole of the base member 27 of the power receiving portion 20. By screwing in, the power receiving portion 20 is fixed to the mounting member 4. As a result, the power receiving unit 20 is attached to the fork portion 302 of the electric moving body 3 via the mounting member 4, and the power receiving unit 20 is on the extension line of the axle 311 of the wheel (front wheel 310) included in the electric moving body 3. Have been placed.

上述のように、車輪(前輪310)には高い寸法精度が要求されるので、車軸311の延長線上に受電部20が配置されることで、受電部20の取付位置が精度よく定まる。よって、送電部10と受電部20との相対的な位置ずれを低減できるので、送電部10と受電部20との間の電力の伝達効率の低下を抑制できる。また、受電部20は、ベース部41に対して前輪(車輪)310と反対側で、受電部取付部43に取り付けられており、ベース部41に比べて車輪(前輪310)から離れた位置に配置できるので、受電部20が車輪(前輪310)に接触する可能性を低減できる。また、受電部20は、取付部材4を介して、車輪(前輪310)に対して固定された位置に配置されるので、電動移動体3が移動する場合でも受電部20の位置がぐらつくのを抑制できる。 As described above, since the wheels (front wheels 310) are required to have high dimensional accuracy, the mounting position of the power receiving unit 20 is accurately determined by arranging the power receiving unit 20 on the extension line of the axle 311. Therefore, since the relative positional deviation between the power transmission unit 10 and the power reception unit 20 can be reduced, it is possible to suppress a decrease in the power transmission efficiency between the power transmission unit 10 and the power reception unit 20. Further, the power receiving portion 20 is attached to the power receiving portion mounting portion 43 on the opposite side of the base portion 41 from the front wheel (wheel) 310, and is located at a position farther from the wheel (front wheel 310) than the base portion 41. Since it can be arranged, the possibility that the power receiving unit 20 comes into contact with the wheel (front wheel 310) can be reduced. Further, since the power receiving unit 20 is arranged at a position fixed to the wheels (front wheels 310) via the mounting member 4, the position of the power receiving unit 20 does not wobble even when the electric moving body 3 moves. Can be suppressed.

本実施形態では、フォーク部302に沿って延びている延伸部44が、フォーク部302に固定されるので、延伸部44をフォーク部302に固定する作業がやりやすいという利点がある。 In the present embodiment, since the extending portion 44 extending along the fork portion 302 is fixed to the fork portion 302, there is an advantage that the work of fixing the extending portion 44 to the fork portion 302 can be easily performed.

なお、本実施形態では、取付部材4の延伸部44が、フォーク部302の固定片303に固定されているが、延伸部44はフォーク部302に適宜の方法で固定されていればよい。例えば、合成樹脂製の結束バンドを用いて延伸部44とフォーク部302とを一括りにしてもよいし、フォーク部302とは別体の金具を用いて延伸部44をフォーク部302に固定してもよい。 In the present embodiment, the extending portion 44 of the mounting member 4 is fixed to the fixing piece 303 of the fork portion 302, but the extending portion 44 may be fixed to the fork portion 302 by an appropriate method. For example, the stretched portion 44 and the fork portion 302 may be bundled together by using a binding band made of synthetic resin, or the stretched portion 44 may be fixed to the fork portion 302 by using a metal fitting separate from the fork portion 302. You may.

また、取付部材4が第1部位304以外で車体301に固定される部位は、フォーク部302に限定されず、車体301におけるフォーク部302以外の部位(例えばフレーム等)に取り付けられてもよい。また、取付部材4は、電動移動体3の後輪を保持するフォーク部に取り付けられてもよい。 Further, the portion where the mounting member 4 is fixed to the vehicle body 301 other than the first portion 304 is not limited to the fork portion 302, and may be attached to a portion (for example, a frame or the like) other than the fork portion 302 in the vehicle body 301. Further, the mounting member 4 may be mounted on the fork portion that holds the rear wheel of the electric moving body 3.

The guide portion 57 is a non-contact power supply for guiding the electric moving body 3 (specifically, the wheels of the electric moving body 3, for example, the front wheel 310) to a position where the first surface 12 and the second surface 22 face each other. It is provided in the device 1. The guide portion 57 is provided from the vicinity of the front end to the vicinity of the rear end of the wheel mounting portion 52.

送電モジュール11は、例えばスパイラルコイルのような送電コイルと、送電用電源回路とを合成樹脂製のケース内に収容して構成される。送電モジュール11は、受電部20と対向する第1面12を有している。第1面12の平面視の形状は略円形である。上述したように、送電部10と受電部20との間では電磁誘導方式で非接触給電が行われる。送電モジュール11の送電用電源回路は、台座部51に収容された電源ユニット62と電線19を介して電気的に接続されている。電源ユニット62の電源コード63は台座部51の外部に引き出されている。電源コード63の端部に設けられたプラグ64を非接触給電装置1の設置場所に設けられたコンセントに接続すると、電源ユニット62に電力が供給され、電源ユニット62は送電用電源回路に対して所定の電圧値(例えばDC24V)の直流電圧を供給する。送電用電源回路は、電源ユニット62から供給された直流電圧を所定周波数の高周波電流に変換して送電コイルに供給する。 The power transmission module 11 is configured by accommodating a power transmission coil such as a spiral coil and a power transmission circuit for power transmission in a case made of synthetic resin. The power transmission module 11 has a first surface 12 facing the power receiving unit 20. The shape of the first surface 12 in a plan view is substantially circular. As described above, non-contact power supply is performed between the power transmission unit 10 and the power reception unit 20 by an electromagnetic induction method. The power transmission circuit of the power transmission module 11 is electrically connected to the power supply unit 62 housed in the pedestal portion 51 via an electric wire 19. The power cord 63 of the power supply unit 62 is pulled out to the outside of the pedestal portion 51. When the plug 64 provided at the end of the power cord 63 is connected to the outlet provided at the installation location of the non-contact power supply device 1, power is supplied to the power supply unit 62, and the power supply unit 62 is connected to the power transmission circuit. A DC voltage having a predetermined voltage value (for example, 24V DC) is supplied. The power transmission circuit converts the DC voltage supplied from the power supply unit 62 into a high-frequency current having a predetermined frequency and supplies the DC voltage to the power transmission coil.

ここで、車輪載置部52に電動移動体3の前輪310が載せられていない待機状態では、送電用電源回路は、蓄電池320の充電時に比べて小さい待機電流を送電コイルに流している。車輪載置部52に電動移動体3の前輪310が載せられ、送電部10の第1面12と受電部20の第2面22とが対向すると、送電コイルと受電コイルとの間に誘導磁束が発生し、受電コイルに高周波の電流が流れる。受電コイルに高周波の電流が流れることによって受電側電源回路に電力が供給されると、受電側電源回路が起動し、受電側電源回路と送電側電源回路との間で通信が行われる。送電側電源回路は、受電側電源回路との通信によって車輪載置部52に電動移動体3の前輪310が載せられたことを検知すると、待機電流に比べて大きな電流を送電コイルに流し、蓄電池320を充電するのに必要な電力を受電部20に供給する。 Here, in the standby state in which the front wheel 310 of the electric moving body 3 is not mounted on the wheel mounting portion 52, the power transmission power supply circuit sends a smaller standby current to the power transmission coil than when the storage battery 320 is charged. When the front wheel 310 of the electric moving body 3 is mounted on the wheel mounting portion 52 and the first surface 12 of the power transmission unit 10 and the second surface 22 of the power receiving unit 20 face each other, an induced magnetic flux is generated between the power transmitting coil and the power receiving coil. Is generated, and a high-frequency current flows through the power receiving coil. When power is supplied to the power receiving side power supply circuit by flowing a high frequency current through the power receiving coil, the power receiving side power supply circuit is activated and communication is performed between the power receiving side power supply circuit and the power transmitting side power supply circuit. When the power transmission side power supply circuit detects that the front wheel 310 of the electric moving body 3 is mounted on the wheel mounting portion 52 by communication with the power reception side power supply circuit, a current larger than the standby current is passed through the power transmission coil, and the storage battery The power required to charge the 320 is supplied to the power receiving unit 20.

ベース部材17は円板状の金属板からなり、ベース部材17の一面に送電モジュール11がねじ又はスナップフィット等の適宜の方法で取り付けられている。また、ベース部材17の一面には、送電モジュール11を覆うようにして、送電側カバー13がねじ又はスナップフィット等の適宜の方法で取り付けられている。 The base member 17 is made of a disk-shaped metal plate, and a power transmission module 11 is attached to one surface of the base member 17 by an appropriate method such as a screw or a snap fit. Further, a power transmission side cover 13 is attached to one surface of the base member 17 by an appropriate method such as a screw or a snap fit so as to cover the power transmission module 11.

送電側カバー13は、図4及び図5に示すように円環状の前壁14と、前壁14の外周縁から受電部20と反対側に突出する周壁16とを備えている。前壁14の中央には、送電モジュール11の第1面12を露出させる円形の窓孔15が設けられている。前壁14の表面は、外側に行くほど受電部20から離れる向きに傾斜する傾斜面14Aとなっている。 As shown in FIGS. 4 and 5, the power transmission side cover 13 includes an annular front wall 14 and a peripheral wall 16 projecting from the outer peripheral edge of the front wall 14 to the side opposite to the power receiving portion 20. In the center of the front wall 14, a circular window hole 15 for exposing the first surface 12 of the power transmission module 11 is provided. The surface of the front wall 14 is an inclined surface 14A that inclines toward the outside toward the power receiving portion 20.

ここにおいて、窓孔15から露出する第1面12と、送電側カバー13とで、送電コイルを覆う第1カバー部18(図2及び図4参照)が構成される。つまり、送電部10は、送電コイルと、第1面12を含んで送電コイルを覆う第1カバー部18とを有している。なお、本実施形態では第1面12と、送電側カバー13とが別体であるが、第1面12を有する送電モジュール11と送電側カバー13とが一体の部品(第1カバー部18)として形成されてもよい。また、送電側カバー13が、送電モジュール11におけるベース部材17と反対側の面を覆ってもよく、この場合は送電側カバー13の表面が第1面12となる。 Here, the first surface 12 exposed from the window hole 15 and the power transmission side cover 13 form a first cover portion 18 (see FIGS. 2 and 4) that covers the power transmission coil. That is, the power transmission unit 10 has a power transmission coil and a first cover unit 18 that includes the first surface 12 and covers the power transmission coil. In the present embodiment, the first surface 12 and the power transmission side cover 13 are separate bodies, but the power transmission module 11 having the first surface 12 and the power transmission side cover 13 are integrated parts (first cover portion 18). May be formed as. Further, the power transmission side cover 13 may cover the surface of the power transmission module 11 opposite to the base member 17, and in this case, the surface of the power transmission side cover 13 becomes the first surface 12.

送電部10は、支持部70を介して、支柱部53内に配置されたフレーム55に取り付けられている。支持部70は、支持点SP1(図2参照)を中心として任意の方向に回転可能な状態で送電部10を支持している。また、支持部70は、送電部10と受電部20とが対向する対向方向(矢印DR1又はDR2の方向)において変位可能な状態でフレーム55に対して取り付けられており、コイルばね90(保持部)によって受電部20側に押し付けられている。つまり、保持部(コイルばね90)は、第1面12と第2面22とを弾性力で押し付けている。 The power transmission unit 10 is attached to the frame 55 arranged in the support column 53 via the support unit 70. The support unit 70 supports the power transmission unit 10 in a state of being rotatable in an arbitrary direction about the support point SP1 (see FIG. 2). Further, the support portion 70 is attached to the frame 55 in a displaceable state in the opposite direction (direction of arrow DR1 or DR2) in which the power transmission portion 10 and the power receiving portion 20 face each other, and the coil spring 90 (holding portion). ) Is pressed against the power receiving unit 20 side. That is, the holding portion (coil spring 90) presses the first surface 12 and the second surface 22 with an elastic force.

支持部70は、取付板71と、ジョイント部材73と、スライド部材77とを備えている。 The support portion 70 includes a mounting plate 71, a joint member 73, and a slide member 77.

取付板71は金属製の板金に曲げ加工を施して形成されている。取付板71における送電部10側の面には、送電部10側に突出するL形の脚部72が複数(例えば4つ)設けられており、各脚部72の先端にベース部材17がねじ又はスナップフィット等の適宜の方法で固定されている。取付板71において、送電部10と反対側の面には、コイルばね90の一端側をガイドする円環状のガイド部材82が取り付けられている。 The mounting plate 71 is formed by bending a metal sheet metal. A plurality of (for example, four) L-shaped legs 72 protruding toward the power transmission section 10 are provided on the surface of the mounting plate 71 on the power transmission section 10 side, and the base member 17 is screwed to the tip of each leg portion 72. Alternatively, it is fixed by an appropriate method such as snap fit. An annular guide member 82 that guides one end side of the coil spring 90 is attached to the surface of the mounting plate 71 opposite to the power transmission unit 10.

ジョイント部材73は、図2に示すように、一端側にボール部75が設けられたシャフト74と、ボール部75を任意の方向に回転可能な状態で支持するソケット76とを備えている。シャフト74におけるボール部75と反対側の端部は、取付板71において送電部10の中心位置に対応する部位に固定されている。 As shown in FIG. 2, the joint member 73 includes a shaft 74 provided with a ball portion 75 on one end side, and a socket 76 that supports the ball portion 75 in a state of being rotatable in an arbitrary direction. The end of the shaft 74 opposite to the ball portion 75 is fixed to a portion of the mounting plate 71 corresponding to the center position of the power transmission portion 10.

スライド部材77は、送電部10と受電部20とが対向する対向方向(矢印DR1又はDR2の方向)に沿って延びる円筒状に形成されている。このスライド部材77にはソケット76が固定されている。フレーム55には、対向方向(矢印DR1又はDR2の方向)においてスライド部材77を変位可能な状態で支持するホルダ部材79が取り付けられている。ホルダ部材79には、このホルダ部材79を対向方向において貫通する貫通孔80が形成されており、この貫通孔80にはスライド部材77の一端側(左側)が挿入されている。スライド部材77の他端側には貫通孔80の内径よりも大きな外径を有する大径部78が設けられている。また、ホルダ部材79の一端側には貫通孔80の内径よりも外径が大きい円板状の抜け止板81が取り付けられている。これにより、スライド部材77は、大径部78又は抜け止板81がホルダ部材79における貫通孔80の周縁部分と当接することによって、その移動範囲が制限されている。 The slide member 77 is formed in a cylindrical shape extending along an opposite direction (direction of arrow DR1 or DR2) in which the power transmission unit 10 and the power reception unit 20 face each other. A socket 76 is fixed to the slide member 77. A holder member 79 that supports the slide member 77 in a displaceable state in the facing direction (direction of arrow DR1 or DR2) is attached to the frame 55. The holder member 79 is formed with a through hole 80 that penetrates the holder member 79 in the opposite direction, and one end side (left side) of the slide member 77 is inserted into the through hole 80. A large diameter portion 78 having an outer diameter larger than the inner diameter of the through hole 80 is provided on the other end side of the slide member 77. Further, a disc-shaped retaining plate 81 having an outer diameter larger than the inner diameter of the through hole 80 is attached to one end side of the holder member 79. As a result, the movement range of the slide member 77 is limited by the large diameter portion 78 or the retaining plate 81 coming into contact with the peripheral edge portion of the through hole 80 in the holder member 79.

ここにおいて、送電部10は取付板71に取り付けられており、送電部10にはジョイント部材73のシャフト74が固定されている。ジョイント部材73のソケット76はスライド部材77に固定されており、スライド部材77は、フレーム55に固定されたホルダ部材79に対して、対向方向において変位可能な状態で取り付けられている。そして、ホルダ部材79と取付板71との間にはコイルばね90が取り付けられており、コイルばね90の弾性力で取付板71がホルダ部材79から離れる方向に押されることによって、送電部10がホルダ部材79から離れる方向に押されている。したがって、電動移動体3の前輪310が車輪載置部52に置かれた状態では、コイルばね90の弾性力によって、送電部10の第1面12と受電部20の第2面22とが互いに押し付けられた状態で接触している。 Here, the power transmission unit 10 is attached to the mounting plate 71, and the shaft 74 of the joint member 73 is fixed to the power transmission unit 10. The socket 76 of the joint member 73 is fixed to the slide member 77, and the slide member 77 is attached to the holder member 79 fixed to the frame 55 in a displaceable state in the opposite direction. A coil spring 90 is attached between the holder member 79 and the mounting plate 71, and the elastic force of the coil spring 90 pushes the mounting plate 71 away from the holder member 79, thereby causing the power transmission unit 10 to move. It is pushed away from the holder member 79. Therefore, when the front wheel 310 of the electric moving body 3 is placed on the wheel mounting portion 52, the elastic force of the coil spring 90 causes the first surface 12 of the power transmission unit 10 and the second surface 22 of the power receiving unit 20 to move from each other. They are in contact while being pressed.

本実施形態では、保持部であるコイルばね90が第1面12と第2面22とを弾性力で押し付けている。保持部であるコイルばね90が、第1面12と第2面22とを弾性力で押し付けることによって、送電部10と受電部20との相対的な位置のずれを低減できる。さらに言えば送電部10が対向方向(矢印DR1又は矢印DR2の方向)において変位可能であり、保持部は、弾性力によって送電部10を受電部20側に押し付ける弾性部材(コイルばね90)を含んでいる。したがって、電動移動体3に人等の物体がぶつかったり、電動移動体3に風が当たったりすることで、前輪310の位置が動いたとしても、第1面12と第2面22との間に隙間ができにくくなり、第1面12と第2面22との接触位置がずれにくくなる。よって、送電部10と受電部20との間で電力を伝達する伝達効率の低下を抑制することができる。 In the present embodiment, the coil spring 90, which is a holding portion, presses the first surface 12 and the second surface 22 with an elastic force. The coil spring 90, which is the holding portion, presses the first surface 12 and the second surface 22 with an elastic force, so that the relative positional deviation between the power transmission unit 10 and the power reception unit 20 can be reduced. Furthermore, the power transmitting unit 10 can be displaced in the opposite direction (direction of arrow DR1 or arrow DR2), and the holding unit includes an elastic member (coil spring 90) that presses the power transmitting unit 10 toward the power receiving unit 20 by an elastic force. I'm out. Therefore, even if the position of the front wheel 310 moves due to an object such as a person colliding with the electric moving body 3 or the wind hitting the electric moving body 3, between the first surface 12 and the second surface 22. It becomes difficult for a gap to be formed in the surface, and the contact position between the first surface 12 and the second surface 22 is less likely to shift. Therefore, it is possible to suppress a decrease in transmission efficiency for transmitting electric power between the power transmission unit 10 and the power reception unit 20.

また、送電部10が取り付けられる取付板71はジョイント部材73を介してスライド部材77に固定されているので、送電部10を支持点SP1を中心として任意の方向に回転させることができる。ここで、ジョイント部材73が支持点SP1を中心として任意の方向に送電部10を回転可能であるとは、支持点SP1を通りかつシャフト74に沿って延びる線分と直交する平面内で送電部10を任意の方向(360度全ての方向)に移動可能なことをいう。例えば、X−Y平面においてはジョイント部材73は送電部10を上下方向(図2の矢印DR3又は矢印DR4に示す方向)に回転させることができる。なお、図2に示す送電部10の回転方向はX−Y平面に限った場合の回転方向であり、実際には任意の方向に回転可能である。 Further, since the mounting plate 71 to which the power transmission unit 10 is attached is fixed to the slide member 77 via the joint member 73, the power transmission unit 10 can be rotated in any direction about the support point SP1. Here, the fact that the joint member 73 can rotate the power transmission unit 10 in an arbitrary direction about the support point SP1 means that the power transmission unit 73 can rotate in a plane orthogonal to the line segment extending through the support point SP1 and along the shaft 74. It means that 10 can be moved in any direction (all directions of 360 degrees). For example, in the XY plane, the joint member 73 can rotate the power transmission unit 10 in the vertical direction (direction indicated by arrow DR3 or arrow DR4 in FIG. 2). The rotation direction of the power transmission unit 10 shown in FIG. 2 is the rotation direction when limited to the XY plane, and can actually rotate in any direction.

したがって、電動移動体3に人等がぶつかったり、電動移動体3に風が当たったりすることで、前輪310の向きが変わったとしても、第2面22の向きに合わせて、第1面12の向きを変えることができ、第1面12と第2面22との間に隙間ができにくくなる。よって、送電部10と受電部20との間で電力を伝達する伝達効率の低下を抑制することができる。 Therefore, even if the direction of the front wheel 310 changes due to a person or the like colliding with the electric moving body 3 or the wind hitting the electric moving body 3, the first surface 12 matches the direction of the second surface 22. The direction of the surface can be changed, and a gap is less likely to be formed between the first surface 12 and the second surface 22. Therefore, it is possible to suppress a decrease in transmission efficiency for transmitting electric power between the power transmission unit 10 and the power reception unit 20.

なお、支持部70は、送電部10を支持点SP1を中心に全周方向で回転自在に支持しているため、送電部10の重みで送電部10の第1面12が下側を向く可能性がある。そこで、非接触給電装置1は、送電部10の第1面12の向きを所定の範囲に制限するための制限部材を備えている。 Since the support unit 70 rotatably supports the power transmission unit 10 in the entire circumferential direction around the support point SP1, the first surface 12 of the power transmission unit 10 can face downward due to the weight of the power transmission unit 10. There is sex. Therefore, the non-contact power feeding device 1 is provided with a limiting member for limiting the orientation of the first surface 12 of the power transmission unit 10 to a predetermined range.

制限部材は、送電部10と本体50との間に配置されるばね部材91を含む。ばね部材91は例えばコイルばねからなる。ばね部材91の一端は、送電部10に固定された取付板71に保持され、ばね部材91の他端は、本体50を構成するフレーム55に固定されたホルダ部材79に保持されている。本実施形態では、前後方向において、2つのばね部材91がジョイント部材73を間にして対称な位置に配置されている。これにより、ばね部材91は送電部10と本体50との間に配置され、取付板71をホルダ部材79から離れる向きに押すことで、送電部10の第1面12の向きを所定の範囲に制限している。ばね部材91は、例えば第1面12の法線が水平面となす角度を数度以下の範囲に制限している。なお、本実施形態ではばね部材91が支持点SP1よりも下側に配置されているが、制限部材は、支持点SP1よりも上側に配置され、取付板71をホルダ部材79側に引っ張る向きの弾性力を取付板71に加えるばね部材で構成されてもよい。 The limiting member includes a spring member 91 arranged between the power transmission unit 10 and the main body 50. The spring member 91 is made of, for example, a coil spring. One end of the spring member 91 is held by a mounting plate 71 fixed to the power transmission unit 10, and the other end of the spring member 91 is held by a holder member 79 fixed to the frame 55 constituting the main body 50. In the present embodiment, the two spring members 91 are arranged at symmetrical positions with the joint member 73 in between in the front-rear direction. As a result, the spring member 91 is arranged between the power transmission unit 10 and the main body 50, and by pushing the mounting plate 71 away from the holder member 79, the direction of the first surface 12 of the power transmission unit 10 is set within a predetermined range. It is restricted. For example, the spring member 91 limits the angle formed by the normal of the first surface 12 to the horizontal plane within a range of several degrees or less. In the present embodiment, the spring member 91 is arranged below the support point SP1, but the limiting member is arranged above the support point SP1 and is oriented to pull the mounting plate 71 toward the holder member 79. It may be composed of a spring member that applies an elastic force to the mounting plate 71.

また、本実施形態では、制限部材が紐状部材92を更に含んでいる。紐状部材92は、支持点SP1よりも上側で、本体50と送電部10との間に取り付けられている。紐状部材92は、合成繊維又は天然繊維により紐状に形成されている。具体的には、紐状部材92の一端は、送電部10に固定された取付板71において、支持点SP1よりも上側の部位に固定されている。紐状部材92の他端は、本体50を構成するフレーム55に固定されたホルダ部材79において、支持点SP1よりも上側の部位に固定されている。これにより、紐状部材92の一端が固定された取付板71の部位と、紐状部材92の他端が固定されたホルダ部材79の部位との間隔が紐状部材92の長さ以下に制限されるので、送電部10の第1面12の傾きを所定の範囲に制限することができる。 Further, in the present embodiment, the limiting member further includes the string-shaped member 92. The string-shaped member 92 is attached above the support point SP1 and between the main body 50 and the power transmission unit 10. The string-shaped member 92 is formed in a string shape by synthetic fibers or natural fibers. Specifically, one end of the string-shaped member 92 is fixed to a portion above the support point SP1 in the mounting plate 71 fixed to the power transmission unit 10. The other end of the string-shaped member 92 is fixed to a portion above the support point SP1 in the holder member 79 fixed to the frame 55 constituting the main body 50. As a result, the distance between the portion of the mounting plate 71 to which one end of the string-shaped member 92 is fixed and the portion of the holder member 79 to which the other end of the string-shaped member 92 is fixed is limited to the length of the string-shaped member 92 or less. Therefore, the inclination of the first surface 12 of the power transmission unit 10 can be limited to a predetermined range.

なお、非接触給電装置1が、制限部材としてばね部材91と紐状部材92の両方を備えることは必須ではなく、制限部材はばね部材91及び紐状部材92のいずれか一方のみでもよい。 It is not essential that the non-contact power feeding device 1 includes both the spring member 91 and the string-shaped member 92 as the limiting member, and the limiting member may be only one of the spring member 91 and the string-shaped member 92.

(2.5)動作
次に、本実施形態の非接触給電システムA1において、非接触給電装置1から電動移動体3に保持された非接触受電装置2に給電する動作について説明する。
(2.5) Operation Next, in the non-contact power feeding system A1 of the present embodiment, an operation of feeding power from the non-contact power feeding device 1 to the non-contact power receiving device 2 held by the electric mobile body 3 will be described.

図11及び図12に示すように、電動移動体3のユーザは、電動移動体3を駐車する際に、電動移動体3を押して、電動移動体3の前輪310を非接触給電装置1の車輪載置部52に設けられたガイド部57内に移動させる。このとき、前輪310はガイド部57の傾斜部59に沿って移動し、傾斜部59の頂上付近(図12の位置P1)に到達するまでの間に、電動移動体3に保持された受電部20の受電側カバー23が、非接触給電装置1に保持された送電部10の送電側カバー13と接触する。ユーザが電動移動体3を更に押し、前輪310が傾斜部59の頂上付近を乗り越えて保持溝58に嵌まり込むと(図12の位置P2)、前輪310の車軸311の延長線L1上で送電部10の第1面12と受電部20の第2面22とが対向している状態となる。この状態では、受電部20によって送電部10が支柱部53の内側に入り込む方向(図3の矢印DR5の方向)に押されるので、コイルばね90の弾性力によって第1面12と第2面22とが互いに押し付けられた状態で接触する。第1面12と第2面22とが対向する状態になると、送電部10から受電部20に対して電磁誘導方式で非接触給電が行われ、電動移動体3の充電回路321が蓄電池320を充電する。蓄電池320が満充電になると、充電回路321は蓄電池320の充電を停止するので、蓄電池320の過充電が抑制される。 As shown in FIGS. 11 and 12, when the user of the electric moving body 3 parks the electric moving body 3, the user pushes the electric moving body 3 and makes the front wheel 310 of the electric moving body 3 a wheel of the non-contact power feeding device 1. It is moved into the guide portion 57 provided in the mounting portion 52. At this time, the front wheel 310 moves along the inclined portion 59 of the guide portion 57, and the power receiving portion held by the electric moving body 3 until it reaches the vicinity of the top of the inclined portion 59 (position P1 in FIG. 12). The power receiving side cover 23 of 20 comes into contact with the power transmitting side cover 13 of the power transmission unit 10 held by the non-contact power feeding device 1. When the user further pushes the electric moving body 3 and the front wheel 310 gets over the vicinity of the top of the inclined portion 59 and fits into the holding groove 58 (position P2 in FIG. 12), power is transmitted on the extension line L1 of the axle 311 of the front wheel 310. The first surface 12 of the unit 10 and the second surface 22 of the power receiving unit 20 face each other. In this state, since the power transmitting unit 20 is pushed by the power receiving unit 20 in the direction in which the power transmitting unit 10 enters the inside of the support column 53 (direction of arrow DR5 in FIG. 3), the elastic force of the coil spring 90 causes the first surface 12 and the second surface 22. And are in contact with each other while being pressed against each other. When the first surface 12 and the second surface 22 face each other, non-contact power is supplied from the power transmitting unit 10 to the power receiving unit 20 by an electromagnetic induction method, and the charging circuit 321 of the electric moving body 3 charges the storage battery 320. Charge. When the storage battery 320 is fully charged, the charging circuit 321 stops charging the storage battery 320, so that overcharging of the storage battery 320 is suppressed.

ここで、送電部10は、支持部70により支持点SP1を中心として回転自在に保持されている。また、支持部70は対向方向(矢印DR1又はDR2の方向)において変位可能であり、保持部であるコイルばね90によって第1面12と第2面22とを互いに押し付けられた状態で保持している。したがって、前輪310が傾くことによって受電部20の第2面22の向きが変化したり、第2面22が左右方向において多少ずれたりしても、第1面12と第2面22とを確実に接触させることができる。したがって、送電部10が備える送電コイルと、受電部20が備える受電コイルとの位置ずれを抑制でき、送電部10と受電部20との間での電力の伝達効率の低下を抑制可能な非接触給電システムA1を提供することができる。 Here, the power transmission unit 10 is rotatably held around the support point SP1 by the support unit 70.

Since it can be taken out from 1, the user can use the electric moving body 3.

このように、非接触給電装置1の送電部10は、電動移動体3に設けられた受電部20に電線等を介さずに非接触給電を行っているので、電動移動体3を非接触給電装置1の車輪載置部52に載せるだけで、電動移動体3の蓄電池320を簡単に充電できる。また、電動移動体3を非接触給電装置1から取り出す際も、電動移動体3と非接触給電装置1とが電線等で繋がっていないので、電動移動体3を車輪載置部52から引き出すだけでよく、使い勝手が向上するという利点がある。 In this way, the power transmission unit 10 of the non-contact power supply device 1 performs non-contact power supply to the power receiving unit 20 provided in the electric mobile body 3 without using an electric wire or the like, so that the electric mobile body 3 is non-contact power supply. The storage battery 320 of the electric moving body 3 can be easily charged simply by mounting it on the wheel mounting portion 52 of the device 1. Further, when the electric moving body 3 is taken out from the non-contact power feeding device 1, since the electric moving body 3 and the non-contact power feeding device 1 are not connected by an electric wire or the like, the electric moving body 3 is simply pulled out from the wheel mounting portion 52. It has the advantage of improving usability.
