Description

給電装置Power supply device
　本発明は、車輌に設けられた受電部に給電する給電装置に関する。 The present invention relates to a power feeding device that feeds power to a power receiving unit provided in a vehicle.
　電気自動車等の蓄電池に蓄えた電気を動力源として走行する車輌では、車輌を駐車場に停めた際等の車輌の停車中において、給電装置を用いて蓄電池を充電する必要がある。従来の電磁誘導方式の非接触の給電装置としては、地面に設置されている給電部が、車輌に搭載されている受電部に給電するものが知られている。給電部は、例えば駐車スペース等の車輌が停止する位置の路面側に設けられている。一方、受電部は、車輌の底面の、地面に設置された給電部と対向する位置に設けられている。 In a vehicle that travels using electricity stored in a storage battery such as an electric vehicle as a power source, it is necessary to charge the storage battery using a power supply device while the vehicle is stopped, such as when the vehicle is parked in a parking lot. As a conventional electromagnetic induction type non-contact power supply device, a power supply unit installed on the ground supplies power to a power reception unit mounted on a vehicle is known. The power feeding unit is provided, for example, on the road surface side where a vehicle such as a parking space stops. On the other hand, the power reception unit is provided on the bottom surface of the vehicle at a position facing the power supply unit installed on the ground.
　上記の非接触充電システムでは、受電部と給電部との位置を精度良く合わせないと、充電効率の低下、または漏洩磁界若しくは不要輻射の増大を招く。従来、受電部と給電部との位置合わせの精度を向上させる方法として、以下の方法が知られている。 In the above non-contact charging system, if the positions of the power receiving unit and the power feeding unit are not accurately aligned, the charging efficiency is reduced, or the leakage magnetic field or unnecessary radiation is increased. Conventionally, the following methods are known as methods for improving the accuracy of alignment between the power receiving unit and the power feeding unit.
　即ち、従来は、給電部の給電コイルの位置を動かすことにより受電部と給電部との位置合わせを行う方法が知られている（例えば、特許文献１）。 That is, conventionally, a method of aligning the power receiving unit and the power feeding unit by moving the position of the power feeding coil of the power feeding unit is known (for example, Patent Document 1).
　また、充電システムにおける位置合わせではないが、以下の技術も知られている。例えば、コ字状の金属本体により車を定位置に案内するもの（例えば、特許文献２）、及び乗り上げた車輪の進行方向を乗入部に向けて修正するための傾斜部を設けることにより位置合わせを行うもの（例えば、特許文献３）が知られている。 Also, the following technology is also known, although it is not alignment in the charging system. For example, alignment is achieved by providing a car with a U-shaped metal body to guide the vehicle to a fixed position (for example, Patent Document 2) and an inclined part for correcting the traveling direction of the wheel that has been ridden toward the entry part. (For example, patent document 3) which performs this is known.

　しかしながら、特許文献１においては、給電コイルを可動させるための可動部を設ける必要があるので、構造が複雑になるとともに製造コストが増大するという問題がある。 However, in Patent Document 1, since it is necessary to provide a movable part for moving the feeding coil, there is a problem that the structure becomes complicated and the manufacturing cost increases.
　また、特許文献２、及び特許文献３を充電システムに適用した場合においては、車を目標停車位置に停車させるためには、目標停車位置まで車を直進させる必要がある。従って、車を何度も前後に移動させて車輪を直進方向に向ける必要があり、位置合わせに伴う運転者の負担が増大するという問題がある。 In addition, when Patent Document 2 and Patent Document 3 are applied to the charging system, in order to stop the vehicle at the target stop position, it is necessary to drive the vehicle straight to the target stop position. Therefore, it is necessary to move the vehicle back and forth many times to turn the wheels in the straight direction, and there is a problem that the burden on the driver accompanying the alignment increases.
　本発明の目的は、受電部と給電部との位置合わせの案内を簡易な構造により行うことができるとともに、受電部と給電部との位置合わせの際の運転者の負担を軽減することができる給電装置を提供することである。 The object of the present invention is to provide guidance for positioning between the power receiving unit and the power feeding unit with a simple structure and to reduce the burden on the driver when positioning the power receiving unit and the power feeding unit. It is to provide a power feeding device.
　本発明の給電装置は、車輌に設けられた受電部と対向して前記受電部に対して非接触で給電する給電部と、前記車輌の左車輪と右車輪との間に収まる幅に形成されるとともに、前記車輌の移動方向であって前記車輌が前記給電部から離れる一方向に向かって徐々に幅狭となる形状を有する車輌誘導部材と、を有する構成を採る。 The power supply device of the present invention, a width that fits between the feeding portion, and the left wheel and the right wheel of the prior SL vehicle to power contactlessly to the power receiving unit to face the power receiving portion provided on the vehicle And a vehicle guide member having a shape gradually narrowing in one direction in which the vehicle moves away from the power supply unit.
　本発明によれば、受電部と給電部との位置合わせの案内を簡易な構造により行うことができるとともに、受電部と給電部との位置合わせの際の運転者の負担を軽減することができる。 ADVANTAGE OF THE INVENTION According to this invention, while being able to perform the guidance of alignment with a power receiving part and a power feeding part with a simple structure, the driver | operator's burden at the time of alignment with a power receiving part and a power feeding part can be reduced. .

The power supply apparatus 100 includes a power supply unit 101, a housing 102, and vehicle guide members 103a and 103b.
　給電部１０１は、車輌１５０が駐車スペース１７０内の所定の位置に停車した際に、受電部１５１と対向して受電部１５１に対して給電する。 When the vehicle 150 stops at a predetermined position in the parking space 170, the power supply unit 101 supplies power to the power reception unit 151 so as to face the power reception unit 151.
　筐体１０２は、給電部１０１を有する。 The housing 102 has a power supply unit 101.
　車輌誘導部材１０３ａ、１０３ｂは、給電部１０１の周囲に配置されている。車輌誘導部材１０３ａ、１０３ｂは、給電の際に車輌１５０の左車輪１５２、１５４と右車輪１５３、１５５との間に収まる幅Ｗ１に形成されている。車輌誘導部材１０３ａ、１０３ｂは、車輌１５０の移動方向（図１において紙面と平行な方向）であって給電部１０１から離れる一方向Ｓ１に向かって徐々に幅狭となる形状を有している。車輌誘導部材１０３ａ、１０３ｂは、方向Ｓ１において、給電部１０１よりも突出するように設けられている。 The vehicle guiding members 103 a and 103 b are arranged around the power feeding unit 101. The vehicle guide members 103a and 103b are formed to have a width W1 that fits between the left wheels 152 and 154 and the right wheels 153 and 155 of the vehicle 150 when power is supplied. The vehicle guide members 103a and 103b have a shape that gradually becomes narrower in a direction S1 that is a moving direction of the vehicle 150 (a direction parallel to the paper surface in FIG. 1) and that is away from the power feeding unit 101. The vehicle guide members 103a and 103b are provided so as to protrude from the power feeding unit 101 in the direction S1.
　車輌誘導部材１０３ａ、１０３ｂは、車輌１５０の底面と対向する方向である高さ方向（以下、「高さ方向」と記載する）に厚みを有し、地面から突出するように設けられている。車輌誘導部材１０３ａ、１０３ｂは、筐体１０２よりも方向Ｓ１に突出するように設けられている。 The vehicle guide members 103a and 103b have a thickness in a height direction (hereinafter referred to as “height direction”) that is a direction facing the bottom surface of the vehicle 150, and are provided so as to protrude from the ground. The vehicle guide members 103 a and 103 b are provided so as to protrude in the direction S <b> 1 from the housing 102.
　＜車輌誘導部材の構成＞
　図２は、車輌誘導部材１０３ｂの平面図である。 <Configuration of vehicle guide member>
FIG. 2 is a plan view of the vehicle guide member 103b.
　車輌誘導部材１０３ｂは、平面から見て直角三角形状を有する。車輌誘導部材１０３ｂの長辺部２０１は、短辺部２０２側において筐体１０２（図２において省略）と接する。車輌誘導部材１０３ｂは、長辺部２０１が方向Ｓ１と平行になるように設けられている。車輌誘導部材１０３ｂは、外縁部１１１ｂが方向Ｓ１に対して所定の角度を有するように設けられている。 The vehicle guiding member 103b has a right triangle shape when seen from the plane. The long side portion 201 of the vehicle guiding member 103b is in contact with the casing 102 (omitted in FIG. 2) on the short side portion 202 side. The vehicle guide member 103b is provided such that the long side portion 201 is parallel to the direction S1.

　＜給電を受ける位置までの車輌の誘導方法＞
　図１に示すように、車輌１５０が方向Ｓ１に対して斜めから給電部１０１に接近する際には、破線で示す軌跡Ｒ１を経由する。この際、車輪１５５の内側面１５５ａは、外縁部１１１ｂに沿って移動する。この状態において、車輌１５０が軌跡Ｒ１から外れた場合には、車輪１５５が車輌誘導部材１０３ｂに乗り上げることにより、車輌１５０が振動するとともに傾く。このため、車輌１５０の運転者は、車輌１５０の振動または傾きを感じることにより、車輌１５０が軌跡Ｒ１から外れていることを認識することができる。従って、車輌１５０の運転者は、ハンドルを操作して車輌１５０を軌跡Ｒ１上に戻すことができる。 <Vehicle guidance method to the position to receive power supply>
As shown in FIG. 1, when the vehicle 150 approaches the power feeding unit 101 obliquely with respect to the direction S1, it passes through a locus R1 indicated by a broken line. At this time, the inner side surface 155a of the wheel 155 moves along the outer edge portion 111b. In this state, when the vehicle 150 deviates from the locus R1, the vehicle 150 vibrates and tilts as the wheels 155 ride on the vehicle guide member 103b. For this reason, the driver of the vehicle 150 can recognize that the vehicle 150 is out of the locus R <b> 1 by feeling the vibration or tilt of the vehicle 150. Accordingly, the driver of the vehicle 150 can return the vehicle 150 to the locus R1 by operating the handle.
　一方、車輌１５０は、車輪１５４を車輌誘導部材１０３ａに接触させることなく給電部１０１に近づくことができる。 On the other hand, the vehicle 150 can approach the power supply unit 101 without bringing the wheel 154 into contact with the vehicle guiding member 103a.
　図３は、車輌１５０が給電を受ける位置に停車した場合の車輌誘導システム１０の平面図である。図１の状態から図３の状態まで車輌１５０を移動した後に、給電装置１００は、給電を開始する。 FIG. 3 is a plan view of the vehicle guidance system 10 when the vehicle 150 stops at a position to receive power supply. After moving the vehicle 150 from the state of FIG. 1 to the state of FIG. 3, the power feeding device 100 starts power feeding.
　＜本実施の形態の効果＞
　本実施の形態によれば、車輌の移動方向であって給電部から離れる一方向に向かって徐々に幅狭となる形状を有する車輌誘導部材を設ける。これにより、本実施の形態は、受電部と給電部との位置合わせの案内を簡易な構造により行うことができるとともに、受電部と給電部との位置合わせの際の運転者の負担を軽減することができる。 <Effects of the present embodiment>

As a result, the present embodiment can perform alignment guidance between the power receiving unit and the power feeding unit with a simple structure and reduce the burden on the driver when positioning the power receiving unit and the power feeding unit. be able to.
　また、本実施の形態によれば、高さ方向に厚みを有するように車輌誘導部材を形成する。よって、本実施の形態は、給電装置に接近する車輌が予定のルートを外れた際に車輪が車輌誘導部材に乗り上げ、車輌に対して振動または傾きを与えることができる。これにより、予定のルートを外れたことを運転者に知らせることができる。 Further, according to the present embodiment, the vehicle guide member is formed so as to have a thickness in the height direction. Therefore, in the present embodiment, when the vehicle approaching the power feeding device deviates from the planned route, the wheel rides on the vehicle guide member and can give vibration or inclination to the vehicle. As a result, the driver can be notified that the planned route has been missed.
　また、本実施の形態によれば、車輌誘導部材は筐体よりも車輌の移動方向であって給電部から離れる一方向に突出するように設けられる。よって、本実施の形態は、車輌が給電を受ける位置に接近する際において予定のルートを大きく外れた場合には、車輌は筐体よりも先に車輌誘導部材の上に乗り上げる。これにより、車輌が筐体を踏むことにより筐体が破損することを防ぐことができる。 Further, according to the present embodiment, the vehicle guide member is provided so as to protrude in one direction away from the power feeding unit in the moving direction of the vehicle rather than the housing. Therefore, in the present embodiment, when the vehicle greatly deviates from the planned route when approaching the position to receive power supply, the vehicle rides on the vehicle guiding member before the housing. Thereby, it can prevent that a housing | casing is damaged by a vehicle stepping on a housing | casing.
　＜本実施の形態の変形例＞

The vehicle guide members 601a and 601b are formed to have a width W1 that fits between the left wheels 152 and 154 and the right wheels 153 and 155 of the vehicle 150 when power is supplied. The vehicle guide members 601 a and 601 b have a shape that gradually becomes narrower in one direction S <b> 1 that is the moving direction of the vehicle 150 and that is away from the power supply unit 101. The vehicle guiding members 601a and 601b are provided so as to protrude from the power feeding unit 101 in the direction S1.

FIG. 7 is a plan view of a vehicle guide member 701 in a modification of the present embodiment. In the modification of the present embodiment, the configuration other than the vehicle guiding member 701 is the same as that of the present embodiment.
　図７に示すように、車輌誘導部材７０１の長辺部７０２は、短辺部７０３側において筐体１０２（図７において省略）と接する。車輌誘導部材７０１は、長辺部７０２が方向Ｓ１と平行になるように設けられている。車輌誘導部材７０１の外縁部７０４は、給電部１０１を中心とする円弧状に形成されている。車輌誘導部材７０１は、給電の際に車輌１５０の底面と対向する上面が、外縁部７０４に沿って段差を有するように形成されている。 As shown in FIG. 7, the long side portion 702 of the vehicle guiding member 701 is in contact with the housing 102 (omitted in FIG. 7) on the short side portion 703 side. The vehicle guiding member 701 is provided such that the long side portion 702 is parallel to the direction S1. An outer edge portion 704 of the vehicle guiding member 701 is formed in an arc shape centering on the power feeding portion 101. The vehicle guide member 701 is formed such that the top surface facing the bottom surface of the vehicle 150 has a step along the outer edge portion 704 when power is supplied.
　なお、車輌誘導部材７０１と対となる車輌誘導部材は、車輌誘導部材７０１と同一構成であるので、その説明を省略する。 Note that the vehicle guide member paired with the vehicle guide member 701 has the same configuration as that of the vehicle guide member 701, and thus the description thereof is omitted.
　本実施の形態の変形例によれば、上記の実施の形態２の効果に加えて、上面が段差を有するように車輌誘導部材を形成する。これにより、本実施の形態の変形例は、車輌が車輌誘導部材に乗り上げた際に連続的に振動を生じるので、予定のルートを外れたことを運転者に確実に知らせることができる。 According to the modification of the present embodiment, in addition to the effects of the second embodiment, the vehicle guide member is formed so that the upper surface has a step.

<Configuration of charging system>
FIG. 8 is a plan view of vehicle guidance system 50 when vehicle 150 is moving to a position to receive power supply in the fourth embodiment of the present invention.
　図８に示す車輌誘導システム５０は、図１に示す実施の形態１に係る車輌誘導システム１０に対して、給電装置１００の代わりに給電装置８００を有する。なお、図８において、図１と同一構成である部分には同一の符号を付してその説明を省略する。 8 has a power feeding device 800 instead of the power feeding device 100 with respect to the vehicle guidance system 10 according to the first embodiment shown in FIG. In FIG. 8, parts having the same configuration as in FIG.
　車輌誘導システム５０は、給電装置８００及び車輌１５０を有する。 The vehicle guidance system 50 includes a power supply device 800 and a vehicle 150.
　給電装置８００は、給電部１０１が地表から露出するように地面上に設置もしくは埋設される。給電装置８００は、例えば駐車スペース１７０に設けられ、車輌１５０の駐車中に受電部１５１に対して給電する。なお、給電装置８００の構成は後述する。 The power supply device 800 is installed or embedded on the ground such that the power supply unit 101 is exposed from the ground surface. The power supply device 800 is provided in, for example, the parking space 170 and supplies power to the power receiving unit 151 while the vehicle 150 is parked. The configuration of the power supply apparatus 800 will be described later.
　車輌１５０は、給電装置８００により受電部１５１を介して充電された、図示しない蓄電池を動力源として走行する。 The vehicle 150 travels using a storage battery (not shown) charged by the power supply device 800 via the power receiving unit 151 as a power source.
　＜給電装置の構成＞
　給電装置８００は、給電部１０１、筐体１０２及び車輌誘導部材８０１ａ、８０１ｂを有する。 <Configuration of power supply device>
The power supply apparatus 800 includes a power supply unit 101, a housing 102, and vehicle guide members 801a and 801b.
　車輌誘導部材８０１ａ、８０１ｂは、給電部１０１の周囲に配置されている。車輌誘導部材８０１ａ、８０１ｂは、給電の際に車輌１５０の左車輪１５２、１５４と右車輪１５３、１５５との間に収まる幅Ｗ１に形成されている。車輌誘導部材８０１ａ、８０１ｂは、車輌１５０の移動方向であって給電部１０１から離れる一方向Ｓ２に向かって徐々に幅狭となる形状を有している。車輌誘導部材８０１ａ、８０１ｂは、方向Ｓ１において、給電部１０１よりも突出するように設けられている。方向Ｓ１は、例えば、車輌１５０が後退により給電を受ける位置まで直進する際の直進方向である。 The vehicle guiding members 801 a and 801 b are arranged around the power feeding unit 101. The vehicle guide members 801a and 801b are formed to have a width W1 that fits between the left wheels 152 and 154 and the right wheels 153 and 155 of the vehicle 150 when power is supplied. The vehicle guide members 801 a and 801 b have a shape that gradually becomes narrower in one direction S <b> 2 that is the moving direction of the vehicle 150 and that is away from the power supply unit 101. The vehicle guide members 801a and 801b are provided so as to protrude from the power feeding unit 101 in the direction S1. The direction S1 is, for example, a straight traveling direction when the vehicle 150 travels straight to a position where power is received by reversing.
　車輌誘導部材８０１ａ、８０１ｂは、車輌１５０の移動方向であって給電部１０１から離れる一方向Ｓ２に向かって徐々に幅狭となる形状を有している。車輌誘導部材８０１ａ、８０１ｂは、方向Ｓ２において、給電部１０１よりも突出するように設けられている。方向Ｓ２は、方向Ｓ１と反対方向である。方向Ｓ２は、例えば、車輌１５０が前進により給電を受ける位置まで直進する際の直進方向である。 The vehicle guide members 801 a and 801 b have a shape that gradually becomes narrower in one direction S 2 that is the moving direction of the vehicle 150 and is away from the power supply unit 101. The vehicle guide members 801a and 801b are provided so as to protrude from the power feeding unit 101 in the direction S2. The direction S2 is opposite to the direction S1. The direction S2 is, for example, a straight traveling direction when the vehicle 150 travels straight to a position where power is received by advancing.
　給電を受ける位置まで車輌１５０が前進する際に外縁部８１２ａ、８１２ｂによりガイドし、給電を受ける位置まで車輌１５０が後退する際に外縁部８１１ａ、８１１ｂによりガイドすることを想定する。この場合、車輌１５０が進入する角度は、方向Ｓ２に対する角度の方が方向Ｓ１に対する角度よりも小さくなる。従って、この場合には、方向Ｓ２に対する外縁部８１２ａ、８１２ｂの傾斜角度は、方向Ｓ１に対する外縁部８１１ａ、８１１ｂの傾斜角度よりも小さくなるように形成することができる。 It is assumed that the vehicle 150 is guided by the outer edge portions 812a and 812b when the vehicle 150 moves forward to the position to receive power supply, and is guided by the outer edge portions 811a and 811b when the vehicle 150 moves backward to the position to receive power supply. In this case, the angle at which the vehicle 150 enters is smaller for the direction S2 than for the direction S1. Accordingly, in this case, the inclination angle of the outer edge portions 812a and 812b with respect to the direction S2 can be formed to be smaller than the inclination angle of the outer edge portions 811a and 811b with respect to the direction S1.
　車輌誘導部材８０１ａ、８０１ｂは、高さ方向に厚みを有し、地面から突出するように設けられている。車輌誘導部材８０１ａ、８０１ｂは、筐体１０２よりも方向Ｓ１に突出するように設けられている。車輌誘導部材８０１ａ、８０１ｂは、筐体１０２よりも方向Ｓ２に突出するように設けられている。 The vehicle guide members 801a and 801b have a thickness in the height direction and are provided so as to protrude from the ground. The vehicle guide members 801a and 801b are provided so as to protrude in the direction S1 from the housing 102. The vehicle guide members 801a and 801b are provided so as to protrude in the direction S2 from the housing 102.
　＜給電を受ける位置までの車輌の誘導方法＞
　図８に示すように、車輌１５０が方向Ｓ２に対して斜めから給電部１０１に接近する際には、破線で示す軌跡Ｒ２を経由する。この際、車輪１５２の内側面１５２ａは、外縁部８１２ａに沿って移動する。この状態において、車輌１５０が軌跡Ｒ２から外れた場合には、車輪１５２が車輌誘導部材８０１ａに乗り上げることにより、車輌１５０が振動するとともに傾く。このため、車輌１５０の運転者は、車輌１５０の振動または傾きを感じることにより、車輌１５０が軌跡Ｒ２から外れていることを認識することができる。従って、車輌１５０の運転者は、ハンドルを操作して車輌１５０を軌跡Ｒ２上に戻すことができる。 <Vehicle guidance method to the position to receive power supply>
As shown in FIG. 8, when the vehicle 150 approaches the power feeding unit 101 obliquely with respect to the direction S2, the vehicle 150 passes through a locus R2 indicated by a broken line. At this time, the inner side surface 152a of the wheel 152 moves along the outer edge portion 812a. In this state, when the vehicle 150 deviates from the trajectory R2, the vehicle 150 vibrates and tilts as the wheel 152 rides on the vehicle guide member 801a. For this reason, the driver of the vehicle 150 can recognize that the vehicle 150 has deviated from the locus R2 by feeling the vibration or tilt of the vehicle 150. Therefore, the driver of the vehicle 150 can return the vehicle 150 to the locus R2 by operating the handle.
　一方、車輌１５０は、車輪１５３を車輌誘導部材８０１ｂに接触させることなく給電部１０１に近づくことができる。 On the other hand, the vehicle 150 can approach the power supply unit 101 without bringing the wheel 153 into contact with the vehicle guiding member 801b.
　なお、車輌１５０が給電を受ける位置に停車した状態は図３と同様であるので、その説明を省略する。また、車輌１５０が方向Ｓ１に対して斜めから給電部１０１に接近する際の車輌の誘導方法は、上記の実施の形態１と同様であるので、その説明を省略する。 Note that the state where the vehicle 150 stops at a position to receive power supply is the same as in FIG. In addition, since the vehicle guidance method when the vehicle 150 approaches the power supply unit 101 obliquely with respect to the direction S1 is the same as that in the first embodiment, the description thereof is omitted.
　＜本実施の形態の効果＞
　本実施の形態によれば、車輌の移動方向であって給電部から離れる互いに反対方向である二方向に向かって徐々に幅狭となる形状を有する車輌誘導部材を設ける。これにより、本実施の形態は、前進または後退の車輌の駐車方法に寄らずに、上記の実施の形態１と同様の効果を得ることができる。 <Effects of the present embodiment>
According to the present embodiment, the vehicle guide member having a shape that gradually becomes narrower in two directions, which are the moving directions of the vehicle and are opposite to each other and away from the power feeding unit, is provided. Thereby, this Embodiment can acquire the effect similar to said Embodiment 1 without depending on the parking method of the vehicle forward or backward.
　＜本実施の形態の変形例＞
　本実施の形態において、筐体と車輌誘導部材とを別々に形成したが、本発明はこれに限らず、筐体と車輌誘導部材とを一体に形成してもよい。即ち、車輌誘導部材が筐体の一部であってもよい。 <Modification of the present embodiment>
In the present embodiment, the housing and the vehicle guide member are formed separately, but the present invention is not limited to this, and the housing and the vehicle guide member may be formed integrally. That is, the vehicle guide member may be a part of the housing.
　また、本実施の形態において、車輌誘導部材は車輌が前進と後退の双方により給電を受ける位置まで移動する際の案内を行うが、本発明はこれに限らず、車輌誘導部材は車輌が前進により給電を受ける位置まで移動する際の案内を行うような形状にしてもよい。 In the present embodiment, the vehicle guide member provides guidance when the vehicle moves to a position where power is received by both forward and backward movements. However, the present invention is not limited to this, and the vehicle guide member is provided when the vehicle moves forward. You may make it the shape which performs guidance at the time of moving to the position which receives electric power feeding.
　また、本実施の形態において、車輌誘導部材は平面から見て２等辺三角形状を有するように形成したが、本発明はこれに限らず、図５に示すように給電部１０１を中心とする円弧状に外縁部を形成してもよい。 Further, in the present embodiment, the vehicle guide member is formed to have an isosceles triangle shape when viewed from above, but the present invention is not limited to this, and a circle centering on the power feeding portion 101 as shown in FIG. The outer edge may be formed in an arc shape.
　また、本実施の形態において、図７に示すように車輌誘導部材の上面を外縁部に沿って段差を有するように形成してもよいし、図６に示すように外縁部から給電部に向けて、高さ方向に徐々に厚みが増すように形成してもよい。 Further, in the present embodiment, as shown in FIG. 7, the upper surface of the vehicle guide member may be formed to have a step along the outer edge portion, or from the outer edge portion toward the power feeding portion as shown in FIG. The thickness may be gradually increased in the height direction.

　車輌１５０は、給電装置９００により受電部１５１を介して充電された、図示しない蓄電池を動力源として走行する。 The vehicle 150 travels using a storage battery (not shown) charged by the power supply device 900 via the power receiving unit 151 as a power source.
　＜給電装置の構成＞
　給電装置９００は、給電部１０１、筐体１０２及び車輌誘導部材９０１を有する。 <Configuration of power supply device>
The power supply apparatus 900 includes a power supply unit 101, a housing 102, and a vehicle guide member 901.
　車輌誘導部材９０１は、給電部１０１の周囲に配置されている。車輌誘導部材９０１は、給電を受ける車輌１５０の左車輪１５２、１５４と右車輪１５３、１５５とが収まる幅で給電部１０１を挟んで互いに対向する一対のガイド部９０２ａ、９０２ｂを有する。一対のガイド部９０２ａ、９０２ｂは、車輌１５０の移動方向であって給電部１０１から離れる一方向Ｓ３に向かって互いに徐々に離れるように設けられている。ガイド部９０２ａ、９０２ｂは、方向Ｓ３において、給電部１０１よりも突出するように設けられている。 The vehicle guiding member 901 is disposed around the power feeding unit 101. The vehicle guide member 901 has a pair of guide portions 902a and 902b that face each other with the power supply portion 101 interposed therebetween so that the left wheels 152 and 154 and the right wheels 153 and 155 of the vehicle 150 that receives power supply can be accommodated. The pair of guide portions 902a and 902b are provided so as to gradually move away from each other in a direction S3 that is the moving direction of the vehicle 150 and is away from the power feeding portion 101. The guide portions 902a and 902b are provided so as to protrude from the power feeding portion 101 in the direction S3.
　車輌誘導部材９０１は、高さ方向に厚みを有し、地面から突出するように設けられている。車輌誘導部材９０１は、筐体１０２よりも方向Ｓ３に突出するように設けられている。 The vehicle guiding member 901 has a thickness in the height direction and is provided so as to protrude from the ground. The vehicle guide member 901 is provided so as to protrude from the housing 102 in the direction S3.
　＜給電を受ける位置までの車輌の誘導方法＞
　図９に示すように、車輌１５０が方向Ｓ３に対して斜めから給電部１０１に接近する際には、車輪１５４の外側面１５４ｂは、ガイド部９０２ａに沿って移動する。この状態において、車輌１５０が予定のルートから外れた場合には、車輪１５４が車輌誘導部材９０１に乗り上げることにより車輌１５０が振動するとともに傾く。このため、車輌１５０の運転者は、車輌１５０の振動または傾きを感じることにより、車輌１５０が予定のルートから外れていることを認識することができる。従って、車輌１５０の運転者は、ハンドルを操作して車輌１５０を予定のルートに戻すことができる。 <Vehicle guidance method to the position to receive power supply>
As shown in FIG. 9, when the vehicle 150 approaches the power feeding unit 101 obliquely with respect to the direction S3, the outer side surface 154b of the wheel 154 moves along the guide unit 902a. In this state, when the vehicle 150 deviates from the planned route, the vehicle 150 vibrates and tilts as the wheel 154 rides on the vehicle guide member 901. Therefore, the driver of the vehicle 150 can recognize that the vehicle 150 is off the planned route by feeling the vibration or tilt of the vehicle 150. Therefore, the driver of the vehicle 150 can return the vehicle 150 to the planned route by operating the handle.
　一方、車輌１５０は、車輪１５５を車輌誘導部材９０１に接触させることなく給電部１０１に近づくことができる。 On the other hand, the vehicle 150 can approach the power feeding unit 101 without bringing the wheel 155 into contact with the vehicle guiding member 901.
　＜本実施の形態の効果＞
　本実施の形態によれば、車輌の移動方向であって給電部から離れる一方向に向かって互いに徐々に離れる一対のガイド部を設ける。よって、本実施の形態は、受電部と給電部との位置合わせの案内を簡易な構造により行うことができるとともに、受電部と給電部との位置合わせの際の運転者の負担を軽減することができる。 <Effects of the present embodiment>
According to the present embodiment, the pair of guide portions that are gradually separated from each other in one direction away from the power feeding portion in the moving direction of the vehicle is provided. Therefore, the present embodiment can guide the alignment between the power receiving unit and the power feeding unit with a simple structure and reduce the burden on the driver when aligning the power receiving unit and the power feeding unit. Can do.
　また、本実施の形態によれば、高さ方向に厚みを有するように車輌誘導部材を形成する。よって、本実施の形態は、給電装置に接近する車輌が予定のルートを外れた際に車輪が車輌誘導部材に乗り上げ、車輌に対して振動または傾きを与えることができる。これにより、予定のルートを外れたことを運転者に知らせることができる。 Further, according to the present embodiment, the vehicle guide member is formed so as to have a thickness in the height direction. Therefore, in the present embodiment, when the vehicle approaching the power feeding device deviates from the planned route, the wheel rides on the vehicle guide member and can give vibration or inclination to the vehicle. As a result, the driver can be notified that the planned route has been missed.
　また、本実施の形態によれば、車輌誘導部材は筐体よりも車輌の移動方向であって給電部から離れる一方向に突出するように設けられる。よって、本実施の形態は、車輌が給電を受ける位置に接近する際において予定のルートを大きく外れた場合には、車輌は筐体よりも先に車輌誘導部材の上に乗り上げる。これにより、車輌が筐体を踏むことにより筐体が破損することを防ぐことができる。 Further, according to the present embodiment, the vehicle guide member is provided so as to protrude in one direction away from the power feeding unit in the moving direction of the vehicle rather than the housing. Therefore, in the present embodiment, when the vehicle greatly deviates from the planned route when approaching the position to receive power supply, the vehicle rides on the vehicle guiding member before the housing. Thereby, it can prevent that a housing | casing is damaged by a vehicle stepping on a housing | casing.
