Therefore, a garage with a roof such as a conventional example disclosed in the patent document 1 is not necessary, and moreover the arm 2 can be extended within a range where the arm 2 reaches at the opposite side of the electric vehicle 200 over the electric vehicle 200 parked near the body 1. Thus, a charger of this embodiment achieves no constraint in terms of parking direction for the electric vehicle 200 such as a conventional example disclosed in the patent document 2, and can improve usability while being compact-sized and low cost.

Description

本発明は、電気自動車に搭載される蓄電池を充電するための電気自動車用充電装置に関する。   The present invention relates to a charging device for an electric vehicle for charging a storage battery mounted on the electric vehicle.

近年、１００ボルト又は２００ボルトの商用交流電源から充電ケーブルを介して蓄電池が充電される電気自動車(プラグインハイブリッド自動車を含む。以下同じ。)が提供され始めている。そして、電気自動車の提供に併せて、住戸の車庫(駐車スペース)などに設置される電気自動車用充電装置も提供されている。例えば、特許文献１には、車庫の屋根から吊り下げられた伸縮自在の充電ケーブルを備え、車庫に駐車された電気自動車に充電する際に充電ケーブルが延ばされて先端のコネクタが電気自動車の充電口(充電インレット)に接続される電気自動車用充電装置が記載されている。但し、特許文献１記載の従来例では、充電ケーブルが吊り下げ可能である屋根付きの車庫が必要となる。   In recent years, electric vehicles (including plug-in hybrid vehicles; the same applies hereinafter) in which a storage battery is charged from a commercial AC power supply of 100 volts or 200 volts via a charging cable have begun to be provided. Along with the provision of electric vehicles, charging devices for electric vehicles installed in garages (parking spaces) of dwelling units are also provided. For example, Patent Document 1 includes a telescopic charging cable hung from the roof of a garage, and when charging an electric vehicle parked in the garage, the charging cable is extended so that the connector at the end is an electric vehicle. An electric vehicle charging device connected to a charging port (charging inlet) is described. However, the conventional example described in Patent Document 1 requires a roofed garage in which the charging cable can be suspended.

また、特許文献２記載の従来例は、電柱の内部に収納された充電ケーブルと、電柱の上部に折り畳み自在に設けられて充電ケーブルを吊り下げるアームと、アームの先端から垂下された充電ケーブルの先端に設けられるコネクタとを備えている。特許文献２記載の従来例では、屋根付きの車庫に比べて構造が簡単な電柱とアームで構成されるため、特許文献１記載の従来例と比較して小型且つ低コストであるという利点がある。   In addition, the conventional example described in Patent Document 2 includes a charging cable housed inside a utility pole, an arm that is foldable on the top of the utility pole and suspends the charging cable, and a charging cable suspended from the tip of the arm. And a connector provided at the tip. The conventional example described in Patent Document 2 is advantageous in that it is smaller and less expensive than the conventional example described in Patent Document 1 because it is composed of a power pole and an arm that are simpler in structure than a garage with a roof. .

しかしながら、特許文献２記載の従来例では、アームの届く範囲が電気自動車の手前側(電柱に近い側)の側面だけであり、電気自動車の反対側(電柱から遠い側)の側面に充電口が設置されている場合には、充電ケーブルが届かなかった。この場合、電気自動車が駐車される向きを逆にしなければならず、使い勝手が悪くなるという問題があった。   However, in the conventional example described in Patent Document 2, the reach of the arm is only on the front side of the electric vehicle (side near the power pole), and the charging port is on the side opposite to the electric vehicle (side far from the power pole). If installed, the charging cable did not arrive. In this case, the direction in which the electric vehicle is parked must be reversed, and there is a problem that the usability is deteriorated.

本発明は、上記課題に鑑みて為されたものであり、小型及び低コストでありながら使い勝手の向上を図ることを目的とする。   The present invention has been made in view of the above problems, and aims to improve usability while being small and low in cost.

以下、本発明に係る電気自動車用充電装置(以下、「充電装置」と略す。)の実施形態について、図面を参照して詳細に説明する。   Hereinafter, an embodiment of a charging device for an electric vehicle (hereinafter abbreviated as “charging device”) according to the present invention will be described in detail with reference to the drawings.

本実施形態の充電装置は、図１に示すように電気自動車200の駐車スペース近傍の地面100に立設される本体１と、本体１の上部に屈伸自在に設けられるアーム２と、アーム２に保持される充電ケーブル３と、充電ケーブル３の先端に設けられるコネクタ４とを備える。   As shown in FIG. 1, the charging device of the present embodiment includes a main body 1 that is erected on the ground 100 near the parking space of the electric vehicle 200, an arm 2 that is flexibly provided on the upper portion of the main body 1, and an arm 2. A charging cable 3 to be held and a connector 4 provided at the tip of the charging cable 3 are provided.

本体１は、金属製の板材によって有底角筒状に形成され、底の部分(天板10)を上にして地面100に立設される。本体１の内部は空洞になっており、地中に埋設される電線管(図示せず)を通った電源ケーブル110が本体１内部に引き込まれる(図１(ｂ)参照)。本体１内部には端子台５が設けられており、この端子台５に電源ケーブル110の先端側と充電ケーブル３の後端側がそれぞれ結線されることにより、電源ケーブル110と充電ケーブル３とが電気的に接続される(図１(ｂ)参照)。   The main body 1 is formed in a bottomed rectangular tube shape by a metal plate material, and is erected on the ground 100 with the bottom portion (top plate 10) facing up. The inside of the main body 1 is hollow, and the power cable 110 that has passed through a conduit (not shown) buried in the ground is drawn into the main body 1 (see FIG. 1B). A terminal block 5 is provided inside the main body 1, and the power cable 110 and the charging cable 3 are electrically connected to each other by connecting the front end side of the power cable 110 and the rear end side of the charging cable 3 to the terminal block 5, respectively. Connected (see FIG. 1B).

アーム２は、それぞれが充電ケーブル３を保持する複数(図示例では３本)のアーム本体20A，20B，20Cと、複数のアーム本体20A，20B，20C同士を回動自在に連結する１乃至複数(図示例では２つ)の関節部21A，21Bとを有する。アーム本体20A，20B，20Cは何れも金属製の筒体(例えば、角筒)からなる。アーム本体20Aの後端部が本体１の天板10に回動自在に支持されている。そして、アーム本体20Aの先端部とアーム本体20Bの後端部が関節部21Aで連結され、アーム本体20Bの先端部とアーム本体20Cの後端部が関節部21Bで連結されている。関節部21A，21Bは、例えば、曲げ延ばし自在である金属製のベローズ(蛇腹)管からなる。そして、アーム本体20A，20B，20C並びに関節部21A，21Bの内部に充電ケーブル３が挿通され、アーム本体20Cの先端部分の下面から充電ケーブル３が引き出される。但し、本実施形態ではアーム２が屈伸自在である構成を例示したが、これに限定する趣旨ではなく、アーム２が伸縮自在である構成、例えば、太さの異なる複数のアーム本体が入れ子になった構成などであっても構わない。   The arm 2 includes a plurality (three in the illustrated example) of arm bodies 20A, 20B, and 20C that hold the charging cable 3, and one or more that rotatably connect the plurality of arm bodies 20A, 20B, and 20C. It has two joint portions 21A and 21B (in the illustrated example). Each of the arm bodies 20A, 20B, and 20C is made of a metal cylinder (for example, a square cylinder). The rear end portion of the arm main body 20A is rotatably supported by the top plate 10 of the main body 1. The distal end portion of the arm main body 20A and the rear end portion of the arm main body 20B are connected by the joint portion 21A, and the front end portion of the arm main body 20B and the rear end portion of the arm main body 20C are connected by the joint portion 21B. The joint portions 21A and 21B are made of, for example, a metal bellows (bellows) tube that can be bent and extended. Then, the charging cable 3 is inserted into the arm main bodies 20A, 20B, 20C and the joint portions 21A, 21B, and the charging cable 3 is pulled out from the lower surface of the distal end portion of the arm main body 20C. However, in the present embodiment, the configuration in which the arm 2 can be bent and extended has been illustrated. However, the present invention is not limited to this configuration. The configuration may be different.

コネクタ４は充電ケーブル３の先端に設けられており、電気自動車200の充電口(充電インレット)201に挿抜自在に接続される。そして、電源ケーブル110及び充電ケーブルからコネクタ４を介して電気自動車200の充電口201に電力が供給され、その電力で電気自動車200に搭載されている蓄電池が充電される。   The connector 4 is provided at the tip of the charging cable 3 and is detachably connected to a charging port (charging inlet) 201 of the electric vehicle 200. Then, electric power is supplied from the power cable 110 and the charging cable to the charging port 201 of the electric vehicle 200 through the connector 4, and the storage battery mounted on the electric vehicle 200 is charged with the electric power.

ここで、充電口201が設けられる位置は電気自動車200の車種によって異なっている。例えば、図１(ａ)(ｂ)に示すように車体の前方右側の角に充電口201が設けられている車種もあれば、図１(ｃ)(ｄ)に示すように車体の後方右側側面に充電口201が設けられている車種もある。なお、図１では車体の前方左側に本体１が位置する向きで電気自動車200が駐車される。   Here, the position where the charging port 201 is provided differs depending on the type of the electric vehicle 200. For example, as shown in FIGS. 1 (a) and 1 (b), there is a vehicle type in which a charging port 201 is provided at the front right corner of the vehicle body, while in the rear right side of the vehicle body as shown in FIGS. 1 (c) and (d). Some vehicle models have a charging port 201 on the side. In FIG. 1, the electric vehicle 200 is parked in such a direction that the main body 1 is positioned on the front left side of the vehicle body.

前者の電気自動車200に対しては、図１(ａ)(ｂ)に示すようにアーム２が折り畳まれた状態でコネクタ４が充電口201に接続される。一方、後者の電気自動車200に対しては、図１(ｃ)(ｄ)に示すようにアーム２が伸長された状態でコネクタ４が充電口201に接続される。このとき、アーム２の高さ位置が電気自動車200の車高よりも高く、且つ本体１に対してアーム２が水平面内で回動自在に支持されているため、電気自動車200を上方から跨いで電気自動車200の反対側(右側)までアーム２の先端が届くことになる。   For the former electric vehicle 200, as shown in FIGS. 1A and 1B, the connector 4 is connected to the charging port 201 in a state where the arm 2 is folded. On the other hand, for the latter electric vehicle 200, as shown in FIGS. 1C and 1D, the connector 4 is connected to the charging port 201 with the arm 2 extended. At this time, since the height position of the arm 2 is higher than the vehicle height of the electric vehicle 200 and the arm 2 is rotatably supported on the main body 1 in a horizontal plane, the electric vehicle 200 is straddled from above. The tip of the arm 2 reaches the opposite side (right side) of the electric vehicle 200.

このように本実施形態の充電装置では、特許文献１記載の従来例のような屋根付きの車庫が不要であり、しかも、本体１の近傍に駐車される電気自動車200を上方から跨いで電気自動車200の反対側に届く範囲までアーム２が伸長可能である。故に、本実施形態の充電装置によれば、充電ケーブル３がアーム２に支持されているために充電ケーブル３を引き回す作業が容易になり(軽くなり)、また、特許文献２記載の従来例のように電気自動車200が駐車される向きに制約がない。しかも、アーム２に支持されている充電ケーブル３が上方から電気自動車200を跨いでいるため、車体に触れて汚れや傷を付ける可能性が低くなる。その結果、小型及び低コストでありながら使い勝手の向上を図ることができる。   As described above, the charging device according to the present embodiment does not require a garage with a roof as in the conventional example described in Patent Document 1, and also crosses over the electric vehicle 200 parked in the vicinity of the main body 1 from above. The arm 2 can be extended to reach the opposite side of 200. Therefore, according to the charging device of this embodiment, since the charging cable 3 is supported by the arm 2, the operation of drawing the charging cable 3 becomes easy (lightens). There is no restriction on the direction in which the electric vehicle 200 is parked. Moreover, since the charging cable 3 supported by the arm 2 straddles the electric vehicle 200 from above, the possibility of touching the vehicle body and causing dirt and scratches is reduced. As a result, usability can be improved while being small and low cost.

ところで、電気自動車の車高も車種によって異なっており、一般的に、セダン型のものに比較してワンボックス型やミニバン型のものの方が車高が高くなっている。そこで、電気自動車の車高の違いに対応するため、充電装置の本体１が鉛直方向(上下方向)に伸縮自在に構成されることが好ましい。   By the way, the vehicle height of an electric vehicle also differs depending on the vehicle type. Generally, the vehicle height of a one-box type or minivan type is higher than that of a sedan type. Therefore, in order to cope with the difference in the height of the electric vehicle, it is preferable that the main body 1 of the charging device is configured to be extendable in the vertical direction (vertical direction).

例えば、図２に示すように本体１が固定部11と可動部12とで構成され、固定部11内に収納される昇降装置13によって可動部12が上下方向に移動(昇降)されるようにすればよい。昇降装置13は、例えば、油圧シリンダや、電動機を利用して可動部12を支える軸14を上下に駆動するものなどで構わない。なお、後者の場合、電動機にパルスモータが用いられれば、可動部12の移動距離(本体１の高さ)が細かく調整可能である。   For example, as shown in FIG. 2, the main body 1 is composed of a fixed portion 11 and a movable portion 12, and the movable portion 12 is moved (lifted) in the vertical direction by a lifting device 13 housed in the fixed portion 11. do it. The lifting device 13 may be, for example, a hydraulic cylinder or a device that drives the shaft 14 that supports the movable portion 12 up and down using an electric motor. In the latter case, if a pulse motor is used as the electric motor, the moving distance of the movable portion 12 (height of the main body 1) can be finely adjusted.
