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に示すように地面100に立設される本体１と、本体１に対して伸縮自在に設けられるロープ(ワイヤロープ)２と、同じく本体１に対して伸縮自在に設けられる充電ケーブル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 standing on the ground 100, a rope (wire rope) 2 provided to be extendable with respect to the main body 1, and an expansion and contraction with respect to the main body 1. A charging cable 3 provided freely 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。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。   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 facing up. The inside of the main body 1 is hollow, and a power cable 110 that passes through a conduit (not shown) buried in the ground is drawn into the main body 1. 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.

また、本体１内には２つの巻取部10，11が上下に並べて設けられている。上側の巻取部(以下、「第１巻取部」と呼ぶ。)10はロープ２を巻き取るものであり、下側の巻取部(以下、「第２巻取部」と呼ぶ。)11は充電ケーブル３を巻き取るものである。但し、第１巻取部10及び第２巻取部11とも、ロープ２及び充電ケーブル３が引き出される向きの回動をラッチする機構が設けられており、ロープ２及び充電ケーブル３の自重程度では第１巻取部10及び第２巻取部11が回動しないようになっている。なお、図示は省略しているが、第１巻取部10及び第２巻取部11にはハンドルが設けられており、このハンドルを回すことで第１巻取部10及び第２巻取部11にロープ２及び充電ケーブル３が巻き取られる。   In the main body 1, two winding portions 10 and 11 are provided side by side. An upper winding portion (hereinafter referred to as “first winding portion”) 10 winds up the rope 2, and a lower winding portion (hereinafter referred to as “second winding portion”). 11 is for winding the charging cable 3. However, both the first winding unit 10 and the second winding unit 11 are provided with a mechanism for latching the rotation in the direction in which the rope 2 and the charging cable 3 are pulled out. The first winding unit 10 and the second winding unit 11 are prevented from rotating. In addition, although illustration is abbreviate | omitted, the 1st winding part 10 and the 2nd winding part 11 are provided with the handle | steering-wheel, and the 1st winding part 10 and the 2nd winding part are rotated by turning this handle | steering-wheel. The rope 2 and the charging cable 3 are wound around 11.

ロープ２及び充電ケーブル３が多数のリング６に挿通されており、これらのリング６を介して充電ケーブル３がロープ２に懸架される。また、ロープ２の先端には電気自動車200の車体に着脱自在に固定される固定部20が設けられている。固定部20は、図２(ａ)に示すように円柱型の永久磁石21と、永久磁石21の磁極面(円柱の底面)を先端側に露出するようにして永久磁石21を内蔵する固定部本体22とを具備する。固定部本体22は、例えば、合成樹脂成形体からなり、永久磁石21とロープ２の先端がインサート成形される。但し、固定部本体22は合成樹脂成形体に限定されず、金属材料などで形成されても構わない。   The rope 2 and the charging cable 3 are inserted into a large number of rings 6, and the charging cable 3 is suspended from the rope 2 through these rings 6. In addition, a fixed portion 20 that is detachably fixed to the body of the electric vehicle 200 is provided at the tip of the rope 2. As shown in FIG. 2 (a), the fixed portion 20 has a cylindrical permanent magnet 21 and a fixed portion in which the permanent magnet 21 is built in such a manner that the magnetic pole surface (bottom surface of the column) of the permanent magnet 21 is exposed to the tip side. And a main body 22. The fixed portion main body 22 is made of, for example, a synthetic resin molded body, and the permanent magnet 21 and the tip of the rope 2 are insert-molded. However, the fixing portion main body 22 is not limited to a synthetic resin molded body, and may be formed of a metal material or the like.

次に、図３を参照して本実施形態の充電装置の使用方法を説明する。まず、ロープ２並びに充電ケーブル３が本体１から引き出され、ロープ２先端の固定部20が電気自動車200の車体における充電口(充電インレット)201の近くに固定される。このとき、固定部20は、固定部本体22に内蔵されている永久磁石21の磁力によって車体(一般に自動車の車体は鋼板で形成されている)に吸着する(図３(ａ)参照)。故に、固定部20が車体に固定されることより、本体１と電気自動車200との間にロープ２が張り渡される。   Next, with reference to FIG. 3, the usage method of the charging device of this embodiment is demonstrated. First, the rope 2 and the charging cable 3 are pulled out from the main body 1, and the fixing portion 20 at the tip of the rope 2 is fixed near the charging port (charging inlet) 201 in the body of the electric vehicle 200. At this time, the fixed portion 20 is attracted to the vehicle body (generally, the vehicle body of an automobile is formed of a steel plate) by the magnetic force of the permanent magnet 21 incorporated in the fixed portion main body 22 (see FIG. 3A). Therefore, the rope 2 is stretched between the main body 1 and the electric vehicle 200 by fixing the fixing portion 20 to the vehicle body.

一方、充電ケーブル３はリング６を介してロープ２に懸架されているので、従来例のように地面100に這わせられることがない(図３(ｂ)参照)。そして、充電ケーブル３の先端に設けられているコネクタ４が電気自動車200の充電口201に接続されると、電源ケーブル110及び充電ケーブル３からコネクタ４を介して電気自動車200の充電口201に電力が供給されて電気自動車200の蓄電池が充電される。ここで、固定部20の永久磁石21又は固定部本体22の先端面が電気自動車200の車体に直接接触した場合、車体の塗装が剥がれるなどの不具合が生じる虞がある。故に、図２(ｂ)に示すように固定部20の車体に接触する部位(先端部)には、弾性材料からなる接触部23が設けられることが望ましい。この接触部23は、ウレタン樹脂や合成ゴムなどの弾性材料によって円板状に形成され、接着などの方法で固定部本体22の先端面に取り付けられる。而して、固定部20が弾性材料製の接触部23で電気自動車200の車体に接触するため、塗装の剥がれなどの不具合の発生を防ぐことができる。   On the other hand, since the charging cable 3 is suspended from the rope 2 via the ring 6, the charging cable 3 is not placed on the ground 100 as in the conventional example (see FIG. 3B). When the connector 4 provided at the tip of the charging cable 3 is connected to the charging port 201 of the electric vehicle 200, power is supplied from the power cable 110 and the charging cable 3 to the charging port 201 of the electric vehicle 200 via the connector 4. Is supplied and the storage battery of the electric vehicle 200 is charged. Here, when the permanent magnet 21 of the fixed portion 20 or the front end surface of the fixed portion main body 22 is in direct contact with the vehicle body of the electric vehicle 200, there is a possibility that problems such as peeling off of the paint on the vehicle body may occur. Therefore, as shown in FIG. 2B, it is desirable that a contact portion 23 made of an elastic material is provided at a portion (tip portion) that contacts the vehicle body of the fixed portion 20. The contact portion 23 is formed in a disc shape by an elastic material such as urethane resin or synthetic rubber, and is attached to the distal end surface of the fixed portion main body 22 by a method such as adhesion. Thus, since the fixing portion 20 contacts the vehicle body of the electric vehicle 200 through the contact portion 23 made of an elastic material, it is possible to prevent the occurrence of problems such as peeling of the paint.

ところで、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)に示すように車体の後部に充電口201が設けられている車種もあれば、図１(ｂ)に示すように車体の前部に充電口201が設けられている車種もある。なお、図１では車体の後方に本体１が位置する向きで電気自動車200が駐車される。そして、後者の場合、ロープ２及び充電ケーブル３が本体１から引き出される長さを長くすることで固定部20が車体の充電口201の近くに固定され、充電ケーブル３を車体の前方まで誘導してコネクタ４を充電口201に接続させることができる(図１(ｂ)参照)。   By the way, the position where the charging port 201 is provided differs depending on the type of the electric vehicle 200. For example, as shown in FIG. 1 (a), there is a vehicle type in which a charging port 201 is provided at the rear part of the vehicle body, and as shown in FIG. 1 (b), the charging port 201 is provided at the front part of the vehicle body. There is also a car model. In FIG. 1, the electric vehicle 200 is parked in such a direction that the main body 1 is located behind the vehicle body. In the latter case, the length of the rope 2 and the charging cable 3 pulled out from the main body 1 is increased so that the fixing portion 20 is fixed near the charging port 201 of the vehicle body, and the charging cable 3 is guided to the front of the vehicle body. Thus, the connector 4 can be connected to the charging port 201 (see FIG. 1B).

ここで、図４に示すようにリング６に換えて、Ｓ字型のフック７で充電ケーブル３がロープ２に懸架されるようにしても構わない。そして、フック７が用いられる場合、先にロープ２だけが本体１から引き出されて固定部20が電気自動車200に固定され、ロープ２にフック７が引っ掛けられた後、本体１から引き出された充電ケーブル３がフック７に引っ掛けられることでロープ２に懸架される。   Here, as shown in FIG. 4, the charging cable 3 may be suspended on the rope 2 by an S-shaped hook 7 instead of the ring 6. When the hook 7 is used, only the rope 2 is first pulled out from the main body 1, the fixing portion 20 is fixed to the electric vehicle 200, the hook 7 is hooked on the rope 2, and then the charging is pulled out from the main body 1. The cable 3 is suspended on the rope 2 by being hooked on the hook 7.

上述のように本実施形態によれば、固定部20が電気自動車200に固定されることで張り渡されたロープ２に充電ケーブル３が懸架されるので、従来例のように充電ケーブル３が地面に這わせられることがない。したがって、人が充電ケーブル３に躓いたり、充電ケーブル３に付着した土などが車体や衣服を汚してしまう虞が減る。また、充電ケーブル３の荷重がある程度はロープ２で受けられるため、充電ケーブル３の取り回しが容易になる。その結果、安全性及び使い勝手の向上が図れる。また、固定部20が磁力によって電気自動車200の車体に吸着するので、車体への着脱が容易に行えるという利点がある。しかも、使用されないときにはロープ２及び充電ケーブル３がそれぞれ巻取部10，11に巻き取られて本体１内に収納されるので、ロープ２や充電ケーブル３の置き場所が不要になるという利点もある。   As described above, according to the present embodiment, since the charging cable 3 is suspended from the rope 2 that is stretched by fixing the fixing portion 20 to the electric vehicle 200, the charging cable 3 is grounded as in the conventional example. You will not be fooled. Therefore, there is a reduced possibility that a person will crawl on the charging cable 3 or soil attached to the charging cable 3 will contaminate the vehicle body or clothes. Moreover, since the load of the charging cable 3 is received to some extent by the rope 2, the handling of the charging cable 3 becomes easy. As a result, safety and usability can be improved. Further, since the fixing portion 20 is attracted to the vehicle body of the electric vehicle 200 by a magnetic force, there is an advantage that it can be easily attached to and detached from the vehicle body. In addition, when not in use, the rope 2 and the charging cable 3 are wound around the winding portions 10 and 11 and stored in the main body 1, so that there is an advantage that a place for placing the rope 2 and the charging cable 3 becomes unnecessary. .

ところで、図１(ｂ)に示したようにロープ２及び充電ケーブル３が電気自動車200の側方に引き回される場合、ロープ２や充電ケーブル３あるいはリング６が車体に接触して傷を付けてしまう可能性がある。   By the way, as shown in FIG. 1B, when the rope 2 and the charging cable 3 are routed to the side of the electric vehicle 200, the rope 2, the charging cable 3 or the ring 6 comes into contact with the vehicle body and is damaged. There is a possibility that.

そこで、図５に示すように支持部８によってロープ２を途中(固定部20から本体１までの間)の部分で支持することが好ましい。この支持部８は、図６に示すように電気自動車200の車体に固定される固定部80と、固定部80に設けられてロープ２を支持する滑車部81とを有する。固定部80は、円柱型の永久磁石80Aと、永久磁石80Aの磁極面(円柱の底面)を先端側に露出するようにして永久磁石80Aを内蔵する固定部本体80Bと、固定部本体80Bの先端面を覆う接触部80Cとを具備する。固定部本体80Bは、例えば、合成樹脂成形体からなり、永久磁石80Aがインサート成形される。但し、固定部本体80Bは合成樹脂成形体に限定されず、金属材料などで形成されても構わない。接触部80Cは、ウレタン樹脂や合成ゴムなどの弾性材料によって円板状に形成され、接着などの方法で固定部本体80Bの先端面に取り付けられる。   Therefore, as shown in FIG. 5, it is preferable that the rope 2 is supported by the support portion 8 in the middle (between the fixed portion 20 and the main body 1). As shown in FIG. 6, the support portion 8 includes a fixing portion 80 that is fixed to the vehicle body of the electric vehicle 200, and a pulley portion 81 that is provided on the fixing portion 80 and supports the rope 2. The fixed portion 80 includes a cylindrical permanent magnet 80A, a fixed portion main body 80B containing the permanent magnet 80A so that the magnetic pole surface (bottom surface of the column) of the permanent magnet 80A is exposed to the tip side, and a fixed portion main body 80B. And a contact portion 80C covering the front end surface. The fixed portion main body 80B is made of, for example, a synthetic resin molded body, and the permanent magnet 80A is insert-molded. However, the fixing portion main body 80B is not limited to the synthetic resin molded body, and may be formed of a metal material or the like. The contact portion 80C is formed into a disk shape by an elastic material such as urethane resin or synthetic rubber, and is attached to the distal end surface of the fixed portion main body 80B by a method such as adhesion.

滑車部81は、固定部本体80Aの後端面より突出する一対の突片81Aと、軸の両端が外側に突出した滑車81Bとを有し、滑車81Bの軸の両端部が突片81Aの先端部に回動自在に軸支されて構成されている。なお、滑車81Bの幅寸法ｄは、リング６の外径よりも大きいことが望ましい。   The pulley unit 81 has a pair of protruding pieces 81A protruding from the rear end surface of the fixed portion main body 80A, and a pulley 81B with both ends of the shaft protruding outward, and both ends of the shaft of the pulley 81B are the tips of the protruding pieces 81A. It is configured to be pivotally supported by the part. The width d of the pulley 81B is preferably larger than the outer diameter of the ring 6.

而して、図５に示すように支持部８によってロープ２が途中の部分で支持されるため、ロープ２や充電ケーブル３が車体に接触し難くなり、ロープ２や充電ケーブル３あるいはリング６が車体に接触して傷を付けるなどの不具合の発生を防ぐことができる。   Thus, as shown in FIG. 5, the rope 2 is supported by the support portion 8 in the middle, so that the rope 2 and the charging cable 3 are difficult to contact the vehicle body, and the rope 2, the charging cable 3 or the ring 6 It is possible to prevent the occurrence of defects such as scratching by contacting the vehicle body.

ところで、リング６やフック７を使わずにロープ２のみで充電ケーブル３を支えることも可能である。例えば、図７に示すように充電ケーブル３が螺旋状の電線(いわゆるカールコード)で構成されていれば、ロープ２の回りに充電ケーブル３が巻回されることで充電ケーブル３をロープ２のみで支えることができる。   By the way, it is also possible to support the charging cable 3 only by the rope 2 without using the ring 6 or the hook 7. For example, as shown in FIG. 7, if the charging cable 3 is composed of a spiral electric wire (so-called curl cord), the charging cable 3 is wound around the rope 2 so that only the rope 2 is connected. Can be supported.
