本発明は、非接触給電用の車両位置決め装置に関する。 The present invention relates to a vehicle positioning device for non-contact power feeding.
例えば、特許文献１には、車両に設けられた２次コイル（非接触受電部）へ送電するための１次コイル（非接触給電部）が配設された車輪止めについて開示されている。この車輪止めは、車両の車輪が進入可能とされており、当該車輪止めに２次コイルを備えた車両の車輪を進入させると、１次コイルが持ち上がり、２次コイルへ送電されるようになっている。つまり、ここでは、車輪止めに車輪を進入させると、１次コイルが持ち上がることで１次コイルと２次コイルとの相対的な位置関係が確保されるようになっている。 For example, Patent Document 1 discloses a wheel stopper provided with a primary coil (non-contact power feeding unit) for transmitting power to a secondary coil (non-contact power receiving unit) provided in a vehicle. This wheel stopper is configured such that a vehicle wheel can enter, and when the vehicle wheel having a secondary coil enters the wheel stopper, the primary coil is lifted and power is transmitted to the secondary coil. ing. That is, here, when the wheel enters the wheel stopper, the primary coil is lifted to ensure the relative positional relationship between the primary coil and the secondary coil.
しかしながら、この先行技術では、車輪止めに車輪を進入させるため当該車輪止めに対して正確に車両を進入させる必要があり、運転者にとって駐車操作の負担が大きくなってしまう。 However, in this prior art, since the wheel is made to enter the wheel stopper, it is necessary to make the vehicle accurately enter the wheel stopper, which increases the burden of the parking operation for the driver.
本発明は上記事実を考慮し、簡単な駐車操作で非接触給電部と非接触受電部との相対的な位置関係を確保することができる非接触給電用の車両位置決め装置を得ることが目的である。 In view of the above fact, the present invention aims to provide a vehicle positioning device for non-contact power feeding that can secure the relative positional relationship between the non-contact power feeding unit and the non-contact power receiving unit with a simple parking operation. is there.
第１の態様に係る非接触給電用の車両位置決め装置は、車両の車輪が当接することで車輪との当接位置よりもさらに奥方への前記車両の移動を規制する車止め部と、前記車輪が前記車止め部に当接した状態で、当該車両に設けられた非接触受電部が対向し前記非接触受電部へ送電可能とする非接触給電部と、前記車両の幅方向に沿った前記非接触給電部の外側に設けられ、かつ当該車両の前後方向に沿って前記車輪を前記車止め部へ案内する一対の案内部と、前記案内部にそれぞれ形成され、上部から下部へ向かうにつれて互いに離間する方向へ傾斜し前記車輪が乗り上がると当該車輪を前記設置面側へ案内し、又は前記車輪の乗り上がりを運転者に認識させ調整を促す一対の傾斜面と、を有している。 The vehicle positioning device for non-contact power feeding according to the first aspect includes a vehicle stopper that restricts the movement of the vehicle further to the back than the contact position with the wheel by contacting the wheel of the vehicle, and the wheel includes A non-contact power feeding section that is in contact with the vehicle stop section and is opposed to a non-contact power receiving section provided in the vehicle and capable of transmitting power to the non-contact power receiving section, and the non-contact power supply along the width direction of the vehicle A pair of guide portions that are provided outside the power supply portion and that guide the wheels to the vehicle stop portion along the front-rear direction of the vehicle, and directions that are formed on the guide portions and that are separated from each other as they go from the top to the bottom And a pair of inclined surfaces that guide the wheel to the installation surface side when the wheel climbs up and recognize the ride of the wheel to the driver to facilitate adjustment.
第１の態様に係る非接触給電用の車両位置決め装置では、車止め部に車輪が当接した状態で、当該車両に設けられた非接触受電部が非接触給電部に対向し、当該非接触給電部から非接触受電部への送電が可能となる。また、車両の幅方向に沿った非接触給電部の外側には、車輪を車止め部へ案内する一対の案内部が設けられている。 In the vehicle positioning device for non-contact power supply according to the first aspect, the non-contact power receiving unit provided in the vehicle faces the non-contact power supply unit in a state where the wheels are in contact with the vehicle stopper, and the non-contact power supply unit Power transmission from the unit to the non-contact power receiving unit becomes possible.

図１及び図２に示されるように、本実施形態では、車両位置決め装置１０に案内部２０、２２が設けられ、当該案内部２０、２２によって、車両１２の後輪２４、２６が案内されて、車止め部１６に当接するようになっている。そして、車止め部１６に後輪２４、２６が当接した状態で、当該車両１２に設けられた２次コイル３８が１次コイル３０に対して略平行な状態で対向し、当該１次コイル３０から２次コイル３８への送電が可能となる。 As shown in FIG. 1 and FIG. 2, in the present embodiment, guide portions 20 and 22 are provided in the vehicle positioning device 10, and the rear wheels 24 and 26 of the vehicle 12 are guided by the guide portions 20 and 22. The vehicle stop portion 16 is brought into contact with the vehicle stop portion 16. The secondary coil 38 provided in the vehicle 12 faces the primary coil 30 in a substantially parallel state with the rear wheels 24, 26 in contact with the vehicle stopper 16, and the primary coil 30. To the secondary coil 38 can be transmitted.
ここで、図１及び図３（Ａ）、（Ｂ）に示されるように、案内部２０、２２には、その上端部２０Ａ１、２２Ａ１から下端部２０Ａ２、２２Ａ２へ向かうにつれて互いに離間する方向へ傾斜する傾斜面２０Ａ、２２Ａが形成されている。そして、当該傾斜面２０Ａ、２２Ａは、後輪２４、２６が乗り上がると、この後輪２４、２６を床面１４Ａ側へ案内するようになっている。 Here, as shown in FIG. 1 and FIGS. 3 (A) and 3 (B), the guide portions 20 and 22 are inclined in the direction of separating from the upper end portions 20A1 and 22A1 toward the lower end portions 20A2 and 22A2. The inclined surfaces 20A and 22A are formed. The inclined surfaces 20A and 22A guide the rear wheels 24 and 26 to the floor surface 14A side when the rear wheels 24 and 26 ride on.
案内部２０、２２の傾斜面２０Ａ、２２Ａの傾斜角度θ１は、ガレージ１４の床面１４Ａから約６０°となるように設定されているため、図３（Ａ）、（Ｂ）に示されるように、傾斜面２０Ａに後輪２４が乗り上げたときに、自重により、図３（Ｃ）、（Ｄ）に示されるように、当該後輪２４が床面１４Ａ側へ案内される。或いは、案内部２０の傾斜面２０Ａに対して後輪２４が乗り上げたとき、車両１２が傾くことで、運転者は車両位置決め装置１０に対して車両１２がズレた状態で進入したことが認識できるため、車両１２のズレを調整することができる。 Since the inclination angle θ1 of the inclined surfaces 20A and 22A of the guide portions 20 and 22 is set to be about 60 ° from the floor surface 14A of the garage 14, as shown in FIGS. 3 (A) and 3 (B). In addition, when the rear wheel 24 rides on the inclined surface 20A, the rear wheel 24 is guided to the floor surface 14A side by its own weight, as shown in FIGS. 3 (C) and 3 (D). Alternatively, when the rear wheel 24 rides on the inclined surface 20 </ b> A of the guide unit 20, the vehicle 12 tilts so that the driver can recognize that the vehicle 12 has entered the vehicle positioning device 10 in a state of being shifted. Therefore, the deviation of the vehicle 12 can be adjusted.
なお、案内部２０、２２の傾斜面２０Ａ、２２Ａの表面及び設置面１４Ａの一部（後輪２４が通過する部分）において、後輪２４を滑りやすくするためのコート剤を塗布しても良い。また、図３（Ａ）、（Ｂ）では、後輪２４が傾斜面２０Ａに乗り上がった状態が示されているが、後輪２６が傾斜面２２Ａに乗り上がった場合も後輪２４の場合と同様である。 Note that a coating agent for making the rear wheel 24 slippery may be applied to the surfaces of the inclined surfaces 20A and 22A of the guide portions 20 and 22 and a part of the installation surface 14A (the portion through which the rear wheel 24 passes). . 3A and 3B show the state in which the rear wheel 24 rides on the inclined surface 20A, the case where the rear wheel 26 rides on the inclined surface 22A is also the case of the rear wheel 24. It is the same.
２次コイル３８と１次コイル３０とを対向させるに当って、両者の相対位置関係が充電効率に大きく影響してしまう。このため、所定の相対位置を確保する必要があり、そのためには車両位置決め装置１０に対して所定の位置に車両１２を駐車させる必要がある。 In making the secondary coil 38 and the primary coil 30 face each other, the relative positional relationship between the two greatly affects the charging efficiency. For this reason, it is necessary to ensure a predetermined relative position, and for that purpose, it is necessary to park the vehicle 12 at a predetermined position with respect to the vehicle positioning device 10.
したがって、車両位置決め装置１０において、本実施形態を適用すれば、図３（Ａ）、（Ｂ）に示されるように、車両位置決め装置１０に対して車両１２がズレた状態で進入したとしても、図３（Ｃ）、（Ｄ）に示されるように、当該案内部２０、２２に対して車両１２を略平行に導くことができる。 Therefore, if this embodiment is applied to the vehicle positioning device 10, even if the vehicle 12 enters the vehicle positioning device 10 in a shifted state, as shown in FIGS. 3 (A) and 3 (B), As shown in FIGS. 3C and 3D, the vehicle 12 can be guided substantially parallel to the guide portions 20 and 22.
このため、図２に示されるように、車両１２の２次コイル３８を車両位置決め装置１０に設けられた１次コイル３０に対して略平行な状態で対向させることができる。これにより、例えば、２次コイル３８が１次コイル３０に対して、水平方向で傾いた状態、或いは平面視でズレた状態で配置された場合と比較して、２次コイル３８の充電効率を向上させることができる。 Therefore, as shown in FIG. 2, the secondary coil 38 of the vehicle 12 can be opposed to the primary coil 30 provided in the vehicle positioning device 10 in a substantially parallel state. As a result, for example, the charging efficiency of the secondary coil 38 can be improved as compared with the case where the secondary coil 38 is disposed in a state where the secondary coil 38 is inclined in the horizontal direction or in a state shifted in plan view. Can be improved.
つまり、本実施形態では、図３（Ａ）、（Ｂ）に示されるように、案内部２０、２２に対して車両１２がズレた状態で進入したとしても、図３（Ｃ）、（Ｄ）に示されるように、当該案内部２０、２２に対して車両１２を略平行に導くことができる。したがって、図２に示されるように、車両１２の２次コイル３８を車両位置決め装置１０の１次コイル３０に対して所定の位置で対向させるに当って、運転者にとって駐車操作に大きな負担を与えない。つまり、本実施形態では、簡単な駐車操作で２次コイル３８と１次コイル３０との位置関係を確保することができる。 That is, in this embodiment, as shown in FIGS. 3A and 3B, even if the vehicle 12 enters the guide units 20 and 22 in a shifted state, FIGS. ), The vehicle 12 can be guided substantially parallel to the guide portions 20 and 22. Therefore, as shown in FIG. 2, when the secondary coil 38 of the vehicle 12 is opposed to the primary coil 30 of the vehicle positioning device 10 at a predetermined position, a large burden is imposed on the parking operation for the driver. Absent. That is, in this embodiment, the positional relationship between the secondary coil 38 and the primary coil 30 can be ensured by a simple parking operation.
また、本実施形態では、図４に示されるように、案内部２０、２２と台座１８の間には、板状のスペーサ５２が配置可能とされている。車両１２の後輪２４、２６において、対向する内面２４Ａ、２６Ａ側の離間距離（Ｌ２）は、車種によって異なる。このため、当該スペーサ５２を設けることで、案内部２０、２２の下端部２０Ａ２、２２Ａ２同士の離間距離（Ｌ１）を変えることができる。すなわち、どの車種であっても当該車両位置決め装置１０で対応できる。 In the present embodiment, as shown in FIG. 4, a plate-like spacer 52 can be disposed between the guide portions 20 and 22 and the pedestal 18. In the rear wheels 24, 26 of the vehicle 12, the separation distance (L 2) on the facing inner surfaces 24 A, 26 A side varies depending on the vehicle type. For this reason, by providing the spacer 52, the separation distance (L1) between the lower end portions 20A2 and 22A2 of the guide portions 20 and 22 can be changed. That is, any vehicle type can be handled by the vehicle positioning device 10.
さらに、図１及び図４に示されるように、本実施形態では、台座１８には１次コイル３０が収容される収容部４６が設けられているため、１次コイル３０が収容部４６内に収容されることによって、１次コイル３０が外部へ露出しないようにすることができる。 Further, as shown in FIG. 1 and FIG. 4, in this embodiment, the pedestal 18 is provided with a housing portion 46 in which the primary coil 30 is housed, so that the primary coil 30 is in the housing portion 46. By being accommodated, the primary coil 30 can be prevented from being exposed to the outside.
また、本実施形態では、収容部４６を開閉させるカバー５０を設けられている。これにより、１次コイル３０を使用しないときは、カバー５０を閉止させることで、当該１次コイル３０を外部から保護することができる。 In the present embodiment, a cover 50 that opens and closes the accommodating portion 46 is provided. Thereby, when the primary coil 30 is not used, the primary coil 30 can be protected from the outside by closing the cover 50.
また、本実施形態では、車両位置決め装置１０は、非磁性体である硬質ゴム等で構成されている。これにより、１次コイル３０から２次コイル３８（図２参照）への給電時における漏れ磁束を抑制又は防止することができる。その結果、充電効率の低下を抑制又は防止することができる。 Moreover, in this embodiment, the vehicle positioning device 10 is comprised with the hard rubber etc. which are nonmagnetic bodies. Thereby, the leakage magnetic flux at the time of the electric power feeding from the primary coil 30 to the secondary coil 38 (refer FIG. 2) can be suppressed or prevented. As a result, a decrease in charging efficiency can be suppressed or prevented.
以上の実施形態では、ガレージ１４の床面１４Ａが同一平面で形成されている場合、ガレージ１４内に車両１２を駐車させた状態で、車両１２は床面１４Ａに対して略平行に配置されることになる。この場合、車両位置決め装置１０に対して車両１２を好適な位置で駐車させると、２次コイル３８は１次コイル３０に対して略平行に配置される。 In the above embodiment, when the floor surface 14A of the garage 14 is formed on the same plane, the vehicle 12 is arranged substantially parallel to the floor surface 14A in a state where the vehicle 12 is parked in the garage 14. It will be. In this case, when the vehicle 12 is parked at a suitable position with respect to the vehicle positioning device 10, the secondary coil 38 is disposed substantially parallel to the primary coil 30.
しかし、図５に示されるように、ガレージ５８の入口側の床面５８Ａと奥側の床面５８Ｂとが同じ平面上に設けられていない場合、当該ガレージ５８内に車両１２を駐車させた状態で、車両１２は床面５８Ｂに対して平行に配置されない。したがって、車両位置決め装置１０に対して車両１２を好適な位置で駐車させたとしても、２次コイル３８が１次コイル３０に対して傾いた状態で配置されてしまう。 However, as shown in FIG. 5, when the floor 58A on the entrance side of the garage 58 and the floor 58B on the back side are not provided on the same plane, the vehicle 12 is parked in the garage 58. Thus, the vehicle 12 is not arranged parallel to the floor surface 58B. Therefore, even if the vehicle 12 is parked at a suitable position with respect to the vehicle positioning device 10, the secondary coil 38 is disposed in a state inclined with respect to the primary coil 30.
この場合、２次コイル３８を１次コイル３０に対して略平行な状態で対向させる場合と比較して、充電効率は低下する。このため、収容部４６の底壁４６Ａには、載置部材６０が設けられ、１次コイル３０を２次コイル３８に対して略平行にするように調整される。 In this case, the charging efficiency is reduced as compared with the case where the secondary coil 38 is opposed to the primary coil 30 in a substantially parallel state. For this reason, the mounting member 60 is provided on the bottom wall 46 </ b> A of the housing portion 46 and is adjusted so that the primary coil 30 is substantially parallel to the secondary coil 38.
一方、図１に示されるように、車止め部１６の前壁１６Ａは、下端部１６Ａ２から上端部１６Ａ１へ向かうにつれて車止め部１６の後方側へ傾斜している。これにより、後輪２４、２６の前壁１６Ａに対する干渉を抑制し、図示はしないが、車止め部１６の前壁がガレージ１４の床面１４Ａに対して起立した状態で形成された場合と比較して、後輪２４、２６を車止め部１６の後壁１６Ｄへ配置させることができ、平面視で後輪２４、２６と車止め部１６の前部をオーバラップさせることができる。したがって、車両位置決め装置１０を含めた車両１２の駐車スペースを小さくすることができる。 On the other hand, as shown in FIG. 1, the front wall 16A of the car stopper 16 is inclined toward the rear side of the car stopper 16 as it goes from the lower end 16A2 to the upper end 16A1. As a result, interference with the front wall 16A of the rear wheels 24, 26 is suppressed, although not shown, compared with a case where the front wall of the car stopper 16 is formed upright with respect to the floor surface 14A of the garage 14. Thus, the rear wheels 24 and 26 can be disposed on the rear wall 16D of the vehicle stopper 16 and the rear wheels 24 and 26 and the front portion of the vehicle stopper 16 can be overlapped in plan view. Therefore, the parking space of the vehicle 12 including the vehicle positioning device 10 can be reduced.
また、以上の実施形態では、車両１２の後輪２４、２６側に２次コイル３８が配設されているが、前輪５４、５６側に２次コイルが配設された車両においても車両位置決め装置１０は適用可能である。 In the above embodiment, the secondary coil 38 is disposed on the rear wheels 24, 26 side of the vehicle 12. However, the vehicle positioning device is also used in a vehicle in which the secondary coil is disposed on the front wheels 54, 56 side. 10 is applicable.
以上、本発明を実施するための一形態として一実施例を用いて説明したが、本発明はこうした一実施例に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲内において、上述した一実施例に種々の変形及び置換を加えることができる。 As described above, the present invention has been described with reference to one embodiment. However, the present invention is not limited to the embodiment, and the above-described embodiments are within the scope of the present invention. Various modifications and substitutions can be made to the embodiment.
