Description

無線給電システムWireless power supply system
　本発明は、電界結合方式によって無線で受電装置に給電する無線給電システムに関する。 The present invention relates to a wireless power supply system that wirelessly supplies power to a power receiving device using an electric field coupling method.
　無線で受電装置に給電する無線給電システムの一例として、例えば、送電装置及び受電装置を備えた無線電力伝送システムが特許文献１に開示されている。 As an example of a wireless power supply system that wirelessly supplies power to a power receiving device, for example, Patent Document 1 discloses a wireless power transmission system that includes a power transmitting device and a power receiving device.
　特許文献１に開示された無線電力伝送システムでは、送電装置が側面視でＬ形状の筐体を備えている。送電装置の筐体は、載置面と、載置面に対して上方へ略垂直に延びた背もたれ面とを有する。受電装置は、受電装置の底面が載置面側となり、受電装置の背面が背もたれ面側となるように、送電装置に載置される。つまり、受電装置は送電装置に装着される。送電装置の背もたれ面と受電装置の背面との各々に、電極が設けられている。受電装置が送電装置に装着された状態で、送電装置の電極から受電装置の電極へ、電力が無線で伝送される。 In the wireless power transmission system disclosed in Patent Document 1, the power transmission device has an L-shaped housing when viewed from the side. The housing of the power transmission device has a mounting surface and a backrest surface extending substantially perpendicularly upward to the mounting surface. The power receiving device is mounted on the power transmitting device such that the bottom surface of the power receiving device faces the mounting surface and the back surface of the power receiving device faces the backrest surface. That is, the power receiving device is attached to the power transmitting device. An electrode is provided on each of the backrest surface of the power transmitting device and the back surface of the power receiving device. With the power receiving device attached to the power transmitting device, power is wirelessly transmitted from the electrodes of the power transmitting device to the electrodes of the power receiving device.
特許第５５００２６９号公報Japanese Patent No. 5500269
　特許文献１に開示された無線電力伝送システムでは、受電装置は、送電装置に載置されているのみで固定されていない。そのため、受電装置は送電装置に対して位置ずれするおそれがある。送電装置及び受電装置の一方が他方に対して位置ずれすると、対向する電極の一方が他方に対して位置ずれする。これにより、受電装置への給電効率が低下するおそれがある。 In the wireless power transmission system disclosed in Patent Document 1, the power receiving device is only placed on the power transmitting device and is not fixed. Therefore, the power receiving device may be displaced with respect to the power transmitting device. When one of the power transmitting device and the power receiving device is displaced with respect to the other, one of the opposing electrodes is displaced with respect to the other. As a result, the efficiency of power supply to the power receiving device may decrease.
　前述した位置ずれの可能性を低くする手段として、送電装置を制御盤の支持面等に固定配置することが考えられる。しかしながら、送電装置が支持面等に固定配置された場合、送電装置の移動の自由度が失われてしまう。また、受電装置の充電時の位置が、送電装置が固定された位置に限定されてしまい、給電中の受電装置を移動させることができない。つまり、受電装置の移動の自由度も失われてしまう。 As a means of reducing the possibility of the above-mentioned positional deviation, it is conceivable to fix the power transmission device on the support surface of the control panel or the like. However, when the power transmission device is fixedly arranged on a support surface or the like, the freedom of movement of the power transmission device is lost. In addition, the position of the power receiving device during charging is limited to the position where the power transmitting device is fixed, and the power receiving device cannot be moved while power is being supplied. In other words, the degree of freedom of movement of the power receiving device is also lost.
　従って、本発明の目的は、前記課題を解決することにあって、送電装置及び受電装置が互いに位置ずれすることを従来技術より低減しつつ、送電装置及び受電装置の移動の自由度を確保することができる無線給電システムを提供することにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described problems, and to secure the degree of freedom of movement of the power transmission device and the power reception device while reducing the positional deviation of the power transmission device and the power reception device compared to the conventional technology. To provide a wireless power feeding system capable of

　本発明によれば、送電装置及び受電装置が互いに位置ずれすることを従来技術より低減しつつ、送電装置及び受電装置の移動の自由度を確保することができる。 According to the present invention, it is possible to secure the degree of freedom of movement of the power transmission device and the power reception device while reducing the positional deviation of the power transmission device and the power reception device compared to the conventional technology.

　本発明の一態様に係る無線給電システムは、

a power receiving device including a second electrode that wirelessly receives power from the first electrode by an electric field coupling method;
The power receiving device includes a mounting portion for mounting the power transmitting device such that the first electrode and the second electrode are opposed to each other.
　この構成によれば、送電装置は受電装置に装着される。そのため、第１電極の第２電極に対する位置ずれを従来技術より低減することができる。 According to this configuration, the power transmission device is attached to the power reception device. Therefore, positional deviation of the first electrode with respect to the second electrode can be reduced as compared with the prior art.
　この構成によれば、送電装置が受電装置に装着される。そのため、受電装置が送電装置に装着される従来技術のように、送電装置の配置位置によって受電装置の移動の自由度が制限されることはない。また、この構成によれば、送電装置が受電装置に装着された状態で、受電装置を送電装置と一体に移動させることができる。つまり、給電中における送電装置及び受電装置の移動の自由度を確保することができる。 According to this configuration, the power transmission device is attached to the power reception device. Therefore, unlike the prior art in which the power receiving device is attached to the power transmitting device, the position of the power transmitting device does not limit the freedom of movement of the power receiving device. Further, according to this configuration, the power receiving device can be moved integrally with the power transmitting device while the power transmitting device is attached to the power receiving device. In other words, it is possible to secure the degree of freedom of movement of the power transmitting device and the power receiving device during power feeding.

The second electrode and the fourth electrode may be provided for wirelessly receiving power from three electrodes, respectively, and when the power transmission device is attached to the attachment portion, the first electrode and the second electrode are They may face each other, and the third electrode and the fourth electrode may face each other.
　この構成によれば、第３電極を有する送電装置は第４電極を有する受電装置に装着される。そのため、第３電極の第４電極に対する位置ずれを従来技術より低減することができる。 According to this configuration, the power transmitting device having the third electrode is attached to the power receiving device having the fourth electrode. Therefore, positional displacement of the third electrode with respect to the fourth electrode can be reduced as compared with the prior art.
　前記無線給電システムにおいて、前記受電装置は、前記送電装置を前記装着部に装着された状態にロックするロック機構を備えていてもよい。この構成によれば、送電装置が受電装置から意図せず抜け出ることをロック機構によって防止することができる。 In the wireless power supply system, the power receiving device may include a locking mechanism that locks the power transmitting device in a state of being attached to the attachment portion. According to this configuration, the lock mechanism can prevent the power transmitting device from unintentionally slipping out of the power receiving device.
　前記無線給電システムにおいて、前記送電装置は、制御信号を用いて無線通信する第１無線通信部を備えていてもよく、前記受電装置は、前記制御信号を用いて前記第１無線通信部と無線通信する第２無線通信部を備えていてもよい。この構成によれば、送電装置及び受電装置は、送電装置から受電装置への給電に加えて、送電装置と受電装置との間で制御信号を送受信することができる。 In the wireless power feeding system, the power transmitting device may include a first wireless communication unit that wirelessly communicates using a control signal, and the power receiving device wirelessly communicates with the first wireless communication unit using the control signal. A second wireless communication unit for communication may be provided. According to this configuration, the power transmitting device and the power receiving device can transmit and receive control signals between the power transmitting device and the power receiving device, in addition to power supply from the power transmitting device to the power receiving device.
　前記無線給電システムにおいて、前記送電装置はさらに、前記第１無線通信部とは異なる無線通信方式で制御信号を用いて前記第２無線通信部と無線通信する第３無線通信部を備えていてもよく、前記第１無線通信部と前記第３無線通信部とは、前記装着部に選択的に装着されてもよい。この構成によれば、様々な無線通信方式に応じた送電装置を受電装置に装着することができる。 In the wireless power supply system, the power transmission device may further include a third wireless communication unit that wirelessly communicates with the second wireless communication unit using a control signal in a wireless communication scheme different from that of the first wireless communication unit. Preferably, the first wireless communication unit and the third wireless communication unit may be selectively attached to the attachment unit. According to this configuration, it is possible to mount the power transmitting device corresponding to various wireless communication methods to the power receiving device.
　本発明の一態様に係る無線給電システムは、複数の前記受電装置を収容する制御盤を更に備えていてもよい。この構成によれば、制御盤に支持された複数の受電装置を移動させることなく、当該複数の受電装置の各々に送電装置を装着するだけで、当該複数の受電装置へ給電することができる。 The wireless power supply system according to one aspect of the present invention may further include a control panel that accommodates the plurality of power receiving devices.

FIG. 2 is an external perspective view of a control panel on which a plurality of power receiving devices are mounted. The wireless power supply system 10 wirelessly supplies power from the power transmission device 20 to the power reception device 30 by an electric field coupling method.
　図１及び図２に示すように、無線給電システム１０は、送電装置２０と、受電装置３０と、制御盤１００とを備える。 As shown in FIGS. 1 and 2, the wireless power supply system 10 includes a power transmission device 20, a power reception device 30, and a control panel 100.
　送電装置２０は、受電装置３０へ電力を送電する。図１に示すように、送電装置２０は、筐体２１と、電極２２Ａ，２２Ｂと、を備える。電極２２Ａは、第１電極の一例である。電極２２Ｂは、第３電極の一例である。 The power transmission device 20 transmits power to the power reception device 30 .

　電極２２Ａ，２２Ｂは、銅やアルミニウム等の導電体で構成された板状の部材である。第１実施形態において、電極２２Ａ，２２Ｂは、両面が長方形の板形状であるが、このような形状に限らない。例えば、電極２２Ａ，２２Ｂは、円板形状であってもよい。 The electrodes 22A and 22B are plate-shaped members made of a conductor such as copper or aluminum. In the first embodiment, the electrodes 22A and 22B have rectangular plate shapes on both sides, but the shape is not limited to this. For example, electrodes 22A and 22B may be disc-shaped.
　電極２２Ａ，２２Ｂは、交流電源４０と電気的に接続されている。交流電源４０は、電源の一例である。電極２２Ａは、電線６１を介して交流電源４０と電気的に接続されている。電極２２Ｂは、電線６２を介して交流電源４０と電気的に接続されている。電極２２Ａ，２２Ｂには、交流電源４０から電圧が印加される。これにより、交流電源４０から電極２２Ａ，２２Ｂへ電力が供給される。なお、交流電源４０の代わりに、直流電源が設けられ、直流電源と電極２２Ａ，２２ＢとがＤ／Ａコンバータを介して電気的に接続されてもよい。 The electrodes 22A and 22B are electrically connected to an AC power supply 40.

　図２に示すように、受電装置３０は、制御盤１００に搭載される。図２では、３つの受電装置３０が、制御盤１００が備える引き出し１１０の中に収容されている。 As shown in FIG. 2 , the power receiving device 30 is mounted on the control panel 100 . In FIG. 2 , three power receiving devices 30 are housed in a drawer 110 provided on the control panel 100 .
　引き出し１１０の中に収容される受電装置３０の数は、３つに限らず、例えば１つでもよいし、５つでもよい。複数の受電装置３０が引き出し１１０の中に収容されている場合、各受電装置３０の種類は、同一であってもよいし、異なっていてもよい。例えば、図２に示す３つの受電装置３０の全てが温度調節ユニットであってもよいし、３つの受電装置３０が、それぞれ温度調節装置、センサユニット、及び通信ユニットであってもよい。 The number of power receiving devices 30 housed in the drawer 110 is not limited to three, and may be one or five, for example. When a plurality of power receiving devices 30 are accommodated in the drawer 110, the type of each power receiving device 30 may be the same or different. For example, all of the three power receiving devices 30 shown in FIG. 2 may be temperature control units, or the three power receiving devices 30 may each be a temperature control device, a sensor unit, and a communication unit.
　図２では、制御盤１００は１つの引き出し１１０を備えているが、制御盤１００は複数の引き出し１１０を備えていてもよい。この場合、各引き出し１１０に、少なくとも１つの受電装置３０が収容されていてもよい。制御盤１００は、図２に示すような構成に限らない。例えば、制御盤１００は、幅方向に延設されたＤＩＮレールを、上下方向に複数段備えていてもよい。この場合、各ＤＩＮレールに少なくとも１つの受電装置３０が支持され、受電装置３０を支持した各ＤＩＮレールが制御盤１００に収容される。 Although the control panel 100 includes one drawer 110 in FIG. 2, the control panel 100 may include a plurality of drawers 110.

A mounting portion 32 is formed inside the housing 31 . Electrodes 33A and 33B and a load 34 are arranged inside the housing 31 . In the first embodiment, as shown in FIG. 3, the housing 31 has a cubic shape. The housing 31 may have a shape other than a cube.
　第１実施形態において、装着部３２は、筐体３１の外面から筐体３１の内部に亘って形成された凹部である。装着部３２は、筐体３１の外面に形成された開口３２Ａを介して、受電装置３０の外部と連通されている。送電装置２０は、開口３２Ａを介して装着部３２へ挿入される（図３の矢印参照）。これにより、送電装置２０は装着部３２に装着される。装着部３２に装着されている送電装置２０は、開口３２Ａを介して装着部３２から抜き出される。 In the first embodiment, the mounting portion 32 is a recess formed from the outer surface of the housing 31 to the interior of the housing 31 . The mounting portion 32 communicates with the outside of the power receiving device 30 via an opening 32</b>A formed on the outer surface of the housing 31 . The power transmission device 20 is inserted into the mounting portion 32 through the opening 32A (see the arrow in FIG. 3). As a result, the power transmission device 20 is attached to the attachment portion 32 . The power transmission device 20 attached to the attachment portion 32 is extracted from the attachment portion 32 through the opening 32A.
　第１実施形態において、電極３３Ａ，３３Ｂは、装着部３２と近接して配置されている。 In the first embodiment, the electrodes 33A and 33B are arranged close to the mounting portion 32.
　電極３３Ａ，３３Ｂは、第１実施形態において、送電装置２０の電極２２Ａ，２２Ｂと同様に構成されている。つまり、電極３３Ａ，３３Ｂは、銅やアルミニウム等の導電体で構成された板状の部材である。 The electrodes 33A, 33B are configured similarly to the electrodes 22A, 22B of the power transmission device 20 in the first embodiment. That is, the electrodes 33A and 33B are plate-shaped members made of a conductor such as copper or aluminum.
　送電装置２０が装着部３２に装着された状態において、電極３３Ａは送電装置２０の電極２２Ａと対向しており、電極３３Ｂは送電装置２０の電極２２Ｂと対向している。電極３３Ａ，３３Ｂは、それぞれ負荷３４と電気的に接続されている。 When the power transmission device 20 is attached to the attachment portion 32, the electrode 33A faces the electrode 22A of the power transmission device 20, and the electrode 33B faces the electrode 22B of the power transmission device 20.

A circuit forming the load 34 is electrically connected to each of the electrodes 33A and 33B. That is, the electrodes 33A and 33B are electrically connected via the load .
　以上のように構成されることにより、互いに対向した電極２２Ａ，３３Ａと、互いに対向した電極２２Ｂ，３３Ｂとは、それぞれコンデンサとして機能する。送電装置２０が装着部３２に装着された状態において、交流電源４０からの高周波の電流が、当該コンデンサを介して流れる。これにより、電極２２Ａから電極３３Ａ、及び電極２２Ｂから電極３３Ｂへ、無線で電力が供給される。言い換えると、交流電源４０から電極２２Ａ，２２Ｂに交流電圧が印加されることによって、電界結合方式により、電極２２Ａから電極３３Ａへ無線で電力が供給され、電極２２Ｂから電極３３Ｂへ無線で電力が供給される。つまり、電極２２Ａ，２２Ｂは、交流電源４０からの電力を送電し、電極３３Ａ，３３Ｂは、電界結合方式によって電極２２Ａ，２２Ｂからの電力を無線でそれぞれ受電する。 With the configuration described above, the electrodes 22A and 33A facing each other and the electrodes 22B and 33B facing each other function as capacitors. A high-frequency current from the AC power supply 40 flows through the capacitor while the power transmission device 20 is attached to the attachment portion 32 . Thereby, power is wirelessly supplied from the electrode 22A to the electrode 33A and from the electrode 22B to the electrode 33B. In other words, by applying an AC voltage from the AC power supply 40 to the electrodes 22A and 22B, power is wirelessly supplied from the electrode 22A to the electrode 33A, and power is wirelessly supplied from the electrode 22B to the electrode 33B by the electric field coupling method. be done. That is, the electrodes 22A and 22B transmit power from the AC power supply 40, and the electrodes 33A and 33B wirelessly receive the power from the electrodes 22A and 22B by the electric field coupling method.
　電極２２Ａ，２２Ｂの送電装置２０における配置位置、及び電極３３Ａ，３３Ｂの受電装置３０における配置位置は、電界結合方式により、電極２２Ａから電極３３Ａへ、及び電極２２Ｂから電極３３Ｂへ、無線で電力が供給可能な位置であればよい。電極２２Ａの電極３３Ａに対する対向面（以下、電極２２Ａの対向面と記す。）の全面が、電極３３Ａの電極２２Ａに対する対向面（以下、電極３３Ａの対向面と記す。）の全面と必ずしも対向している必要がない。言い換えると、電極２２Ａの対向面の少なくとも一部が、電極３３Ａの対向面の少なくとも一部と対向していればよい。例えば、電極３３Ａの対向面が、電極２２Ａの対向面より大きくてもよい。この場合、電極３３Ａの対向面の一部は、電極２２Ａの対向面と対向し得ない。しかし、電極３３Ａの対向面の別の一部が、電極２２Ａの対向面と対向することによって、電極２２Ａ，３３Ａはコンデンサとして機能可能である。 The arrangement positions of the electrodes 22A and 22B in the power transmitting device 20 and the arrangement positions of the electrodes 33A and 33B in the power receiving device 30 are set so that electric power is wirelessly transmitted from the electrode 22A to the electrode 33A and from the electrode 22B to the electrode 33B by the electric field coupling method. Any position is acceptable as long as it can be supplied. The entire surface of the electrode 22A facing the electrode 33A (hereinafter referred to as the facing surface of the electrode 22A) does not necessarily face the entire surface of the electrode 33A facing the electrode 22A (hereinafter referred to as the facing surface of the electrode 33A). need not be In other words, at least part of the facing surface of the electrode 22A should face at least part of the facing surface of the electrode 33A. For example, the facing surface of electrode 33A may be larger than the facing surface of electrode 22A. In this case, part of the facing surface of electrode 33A cannot face the facing surface of electrode 22A. However, the electrodes 22A and 33A can function as capacitors by having another part of the facing surface of the electrode 33A face the facing surface of the electrode 22A.

Therefore, unlike the conventional technology in which the power receiving device 30 is attached to the power transmitting device 20 , the position of the power transmitting device 20 does not restrict the freedom of movement of the power receiving device 30 . Further, according to the first embodiment, the power receiving device 30 can be moved integrally with the power transmitting device 20 while the power transmitting device 20 is attached to the power receiving device 30 . In other words, the degree of freedom of movement of the power transmitting device 20 and the power receiving device 30 can be secured during power feeding.
　仮に、従来技術のように対向する電極の間の空間が無線給電システムの外部に位置している場合、ユーザの手等が当該空間へ挿入されること等の外的要因によって、送電装置２０から受電装置３０への給電が影響を受けるおそれがある。第１実施形態によれば、送電装置２０が受電装置３０の内部に位置した状態で電極２２Ａから電極３３Ａへの給電が実行される。そのため、給電中の電極２２Ａ及び電極３３Ａに対する外部からのユーザの手等の接触の可能性を従来技術より低くすることができる。その結果、電極２２Ａから電極３３Ａへの給電が外部から影響を受ける可能性を従来技術より低くすることができる。 If the space between the facing electrodes is located outside the wireless power supply system as in the conventional technology, the power transmission device 20 may Power supply to the power receiving device 30 may be affected. According to the first embodiment, power is supplied from the electrode 22A to the electrode 33A while the power transmitting device 20 is positioned inside the power receiving device 30 . Therefore, it is possible to reduce the possibility that the user's hand or the like contacts the electrodes 22A and 33A while power is being supplied from the outside as compared with the prior art. As a result, the possibility that the power supply from the electrode 22A to the electrode 33A is influenced from the outside can be made lower than in the prior art.
　第１実施形態によれば、電極２２Ｂを有する送電装置２０は電極３３Ｂを有する受電装置３０に装着される。そのため、電極２２Ｂの電極３３Ｂに対する位置ずれを従来技術より低減することができる。 According to the first embodiment, the power transmitting device 20 having the electrode 22B is attached to the power receiving device 30 having the electrode 33B.

For example, the electrodes 22A, 22B may be formed on or mounted on the substrate. Further, for example, the power transmission device 20 may not include the housing 21 and may be configured only with the electrodes 22A and 22B. Such an example is described in the third embodiment.

　図５は、本発明の第２実施形態に係る無線給電システムのブロック図である。第２実施形態に係る無線給電システム１０Ａが第１実施形態に係る無線給電システム１０と異なることは、第２実施形態に係る無線給電システム１０Ａでは、送電装置２０及び受電装置３０がそれぞれ接地されていることである。以下、第１実施形態との相違点が説明される。第１実施形態の無線給電システム１０との共通点については、同一の符号が付された上で、その説明は原則省略され、必要に応じて説明される。これは、後述する各実施形態においても同様である。 <Second embodiment>
FIG. 5 is a block diagram of a wireless power feeding system according to the second embodiment of the present invention. The wireless power feeding system 10A according to the second embodiment differs from the wireless power feeding system 10 according to the first embodiment in that the power transmitting device 20 and the power receiving device 30 are grounded in the wireless power feeding system 10A according to the second embodiment. It is that you are. Differences from the first embodiment will be described below. Points in common with the wireless power supply system 10 of the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted in principle, and will be described as necessary. This also applies to each embodiment described later.
　無線給電システム１０Ａの送電装置２０Ａは、電極２２Ａを備える一方で、電極２２Ｂを備えていない。つまり、電極２２Ｂは、送電装置２０Ａの外部に配置されている。そのため、電極２２Ｂは、受電装置３０Ａの装着部３２に装着されない。つまり、電極２２Ｂは、電極３３Ｂと対向しない。電極２２Ｂは、接地されている。送電装置２０Ａのその他の構成は、送電装置２０と同構成である。 The power transmission device 20A of the wireless power supply system 10A has an electrode 22A but does not have an electrode 22B. That is, the electrode 22B is arranged outside the power transmission device 20A. Therefore, the electrode 22B is not attached to the attachment portion 32 of the power receiving device 30A. That is, the electrode 22B does not face the electrode 33B. Electrode 22B is grounded. Other configurations of the power transmission device 20</b>A are the same as those of the power transmission device 20 .
　無線給電システム１０Ａの受電装置３０Ａが備える電極３３Ｂは、接地されている。第２実施形態では、電極３３Ｂは他の電極と対向しない。そのため、電極３３Ｂは、受電装置３０Ａの筐体３１の内部における任意の位置に配置可能である。受電装置３０Ａのその他の構成は、受電装置３０と同構成である。 The electrode 33B included in the power receiving device 30A of the wireless power supply system 10A is grounded. In the second embodiment, electrode 33B does not face other electrodes. Therefore, the electrode 33B can be placed at any position inside the housing 31 of the power receiving device 30A. Other configurations of the power receiving device 30</b>A are the same as those of the power receiving device 30 .
　第２実施形態では、送電装置２０Ａが装着部３２に装着された状態において、互いに対向した電極２２Ａ，３３Ａがコンデンサとして機能する一方で、電極３３Ｂはコンデンサとして機能しない。送電装置２０Ａが装着部３２に装着された状態において、交流電源４０が作動されると、高周波の電流が、電極２２Ａ，３３Ａで構成されたコンデンサを介して流れる。これにより、電極２２Ａから電極３３Ａへ、無線で電力が供給される。つまり、電極２２Ａは、交流電源４０からの電力を送電し、電極３３Ａは、電界結合方式によって電極２２Ａからの電力を無線で受電する。 In the second embodiment, when the power transmission device 20A is mounted on the mounting portion 32, the electrodes 22A and 33A facing each other function as capacitors, while the electrode 33B does not function as a capacitor. When the AC power supply 40 is activated while the power transmission device 20A is attached to the attachment portion 32, a high-frequency current flows through the capacitor formed by the electrodes 22A and 33A. Thereby, power is wirelessly supplied from the electrode 22A to the electrode 33A. That is, the electrode 22A transmits power from the AC power supply 40, and the electrode 33A wirelessly receives power from the electrode 22A by an electric field coupling method.
　第２実施形態によれば、電極２２Ｂが送電装置２０Ａに内蔵されないため、装着部３２に装着される送電装置２０Ａの大型化を抑制することができる。また、第２実施形態によれば、電極３３Ｂの配置位置が電極２２Ｂの位置によって制限されないため、電極３３Ｂの配置位置を柔軟に決定することができる。 According to the second embodiment, since the electrode 22B is not built into the power transmission device 20A, it is possible to suppress the size increase of the power transmission device 20A mounted on the mounting portion 32. Further, according to the second embodiment, the arrangement position of the electrode 33B is not restricted by the position of the electrode 22B, so the arrangement position of the electrode 33B can be determined flexibly.

In the sixth embodiment, the lock mechanism includes a rotating member 36, coil springs 37 and 38, and a support member 39, as shown in FIG.
　筐体３１の外面に、一対の凹部３１Ａが形成されている。一対の凹部３１Ａは、装着部３２を両側から挟んでおり、装着部３２と連続している。 A pair of recesses 31A are formed on the outer surface of the housing 31. The pair of concave portions 31A sandwich the mounting portion 32 from both sides and are continuous with the mounting portion 32 .
　回動部材３６及びコイルばね３７は、一対の凹部３１Ａの各々に収容されている。 The rotating member 36 and the coil spring 37 are housed in each of the pair of recesses 31A.
　回動部材３６は、筐体３１によって回動軸３６Ａを中心として回動可能に支持されている。回動部材３６は、図１０に実線で示すロック姿勢と、図１０に破線で示す解除姿勢とに回動される。回動部材３６は、先端部に凸部３６Ｂを備える。凸部３６Ｂは、装着部３２へ突出している。凸部３６Ｂは、傾斜面３６Ｃを有する。傾斜面３６Ｃは、筐体３１の外側を向いている。 The rotating member 36 is supported by the housing 31 so as to be rotatable around a rotating shaft 36A. The rotating member 36 is rotated between the locking posture indicated by the solid line in FIG. 10 and the releasing posture indicated by the broken line in FIG. The rotating member 36 has a protrusion 36B at its tip. The convex portion 36B protrudes into the mounting portion 32 . The convex portion 36B has an inclined surface 36C. The inclined surface 36C faces the outside of the housing 31 .

The other end of the coil spring 37 is connected to the surface 31Aa forming the recess 31A in the housing 31 . A coil spring 37 urges the rotating member 36 to the locking posture.
　支持部材３９は、装着部３２の奥部に配置されている。コイルばね３８は、支持部材３９と装着部３２の奥面３２Ｂとの間に配置されている。コイルばね３８の一端は、支持部材３９と接続されている。コイルばね３８の他端は、装着部３２の奥面３２Ｂと接続されている。コイルばね３８は、支持部材３９を開口３２Ａへ向けて付勢している。 The support member 39 is arranged in the inner part of the mounting portion 32 .

The power transmission device 20 is inserted into the mounting portion 32 from above in FIG. 10 through the opening 32A. At this time, the power transmission device 20 contacts and pushes the inclined surface 36C of the rotating member 36 from above. As a result, the rotating member 36 rotates from the locking posture to the releasing posture against the biasing force of the coil spring 37 . As a result, the power transmission device 20 is inserted into the mounting portion 32 . When the power transmission device 20 passes through the rotating member 36, the rotating member 36 is biased by the coil spring 37 to rotate from the release posture to the lock posture.

This causes the coil spring 38 to contract. As a result, the support member 39 is biased by the coil spring 38 and pushes the power transmission device 20 out of the mounting portion 32 . However, as described above, since the power transmission device 20 is locked by the rotating member 36 , that is, it is held in a state of being attached to the mounting portion 32 by the rotating member 36 , it cannot come out of the mounting portion 32 . no.
　以下、送電装置２０が装着部３２から取り出される動作が説明される。図１０に示される状態において、回動部材３６がユーザによって手動でロック姿勢から解除姿勢に回動される。すると、送電装置２０は、コイルばね３８の付勢力によって支持部材３９に押される。その結果、送電装置２０の一部が装着部３２から突出した状態となり、送電装置２０は装着部３２から容易に抜き出し可能となる。 The operation of removing the power transmission device 20 from the mounting portion 32 will be described below. In the state shown in FIG. 10, the user manually rotates the rotating member 36 from the locking posture to the releasing posture. Then, the power transmission device 20 is pushed against the support member 39 by the biasing force of the coil spring 38 . As a result, part of the power transmission device 20 protrudes from the mounting portion 32 , and the power transmission device 20 can be easily pulled out from the mounting portion 32 .
　ロック機構の構成は、前述したような図１０に示す構成に限らず、公知の種々の構成が採用され得る。 The configuration of the lock mechanism is not limited to the configuration shown in FIG. 10 as described above, and various known configurations can be adopted.
