以下に本発明の好ましい実施形態を示す。   Preferred embodiments of the present invention are shown below.

図１には、本発明に係る自動車用充電スタンドの実施形態１の全体構成図を示している。本発明に係る自動車用充電スタンド１には、高電圧受電設備等の電力供給源より引き込まれた電気を自動車に供給するため、内部に電力供給源と接続する電源装置（図示しない）や各部を制御する制御部（図示しない）等が収納されており、電気自動車の充電時に該電源装置と電気自動車とを接続する充電用接続手段２として充電用コネクタ２ａと充電用ケーブル２ｃを備えている。また、その正面側には充電の強制停止や断線チェック等の操作を行うための操作スイッチ６、７、８を配置した操作部５と、充電量や金額等を表示する表示部９が配置されると共に、非使用時に、該自動車用充電スタンドの正面位置に保持される充電用コネクタ２ａを被覆するカバー４を備えている。該カバー４の下端には、充電用コネクタ２ａの下端及び充電用ケーブル２ｃを引き出すための切欠きが設けられており、又、該カバー４はバネ等により上向きに付勢されている。また、該カバー４の開閉を検出するカバー開閉検出スイッチが設けられ、カバーが開くと、「カバー開状態」データが自動車用充電スタンド１内に収納された制御部（図示しない）に保持される。   FIG. 1 shows an overall configuration diagram of Embodiment 1 of a charging station for automobiles according to the present invention. In order to supply electricity drawn from a power supply source such as a high-voltage power receiving facility to the automobile, the vehicle charging station 1 according to the present invention has a power supply device (not shown) and each part connected to the power supply source inside. A control unit (not shown) and the like to be controlled are housed, and a charging connector 2a and a charging cable 2c are provided as charging connection means 2 for connecting the power supply device and the electric vehicle when the electric vehicle is charged. Further, on the front side, an operation unit 5 having operation switches 6, 7, and 8 for performing operations such as forced stop of charging and disconnection check, and a display unit 9 for displaying a charge amount, a price, and the like are arranged. And a cover 4 for covering the charging connector 2a held at the front position of the automobile charging stand when not in use. The lower end of the cover 4 is provided with a notch for pulling out the lower end of the charging connector 2a and the charging cable 2c, and the cover 4 is urged upward by a spring or the like. Further, a cover open / close detection switch for detecting the opening / closing of the cover 4 is provided. When the cover is opened, the “cover open state” data is held in a control unit (not shown) housed in the automobile charging stand 1. .

図２には、非使用時に、充電用コネクタ２ａを自動車用充電スタンド１に保持し、前記カバーを開いた状態図を示している。図２に示すように、非使用時には、充電用コネクタ２ａは保持コネクタ３の保持面３ｂ側に形成した差し込み口３ｃに保持されている。保持コネクタ３の内部には各々断線チェック用の配線を備え、カバー４を開いた時に充電用コネクタ２ａが保持コネクタ３に差し込まれた状態で自動的に断線チェックが開始される。   FIG. 2 shows a state in which the charging connector 2a is held on the automobile charging stand 1 and the cover is opened when not in use. As shown in FIG. 2, when not in use, the charging connector 2 a is held in the insertion port 3 c formed on the holding surface 3 b side of the holding connector 3. Each of the holding connectors 3 is provided with a wire for checking disconnection. When the cover 4 is opened, the disconnection check is automatically started in a state where the charging connector 2 a is inserted into the holding connector 3.

断線チェックは、アース線と電源線との電位差を計測することにより行い、自動車用充電スタンド１内に収納された制御部（図示しない）で異常の有無が判断される。断線チェックの結果が「異常無し」と判断された場合には、前記制御部に当該「異常無し」データが保持される。なお、前記制御部に当該「異常無し」データが保持されていない状態では、充電用コネクタ２ａを電気自動車に接続しても充電が開始されない安全構造を採用している。一方、断線チェックの結果が「異常有り」と判断された場合には、当該「異常有り」データを表示部９に表示したり、当該「異常有り」データを管理者へ自動送信して、断線の発生を警告し、感電事故を回避する安全構造を採用している。また、断線チェックの結果が「異常有り」と判断された場合には、前記のように制御部に当該「異常無し」データが保持されていない状態となるため、充電用コネクタ２ａを電気自動車に接続しても充電は開始されない安全構造となっている。   The disconnection check is performed by measuring the potential difference between the ground line and the power line, and the presence or absence of an abnormality is determined by a control unit (not shown) housed in the automobile charging stand 1. When it is determined that the disconnection check result is “no abnormality”, the “no abnormality” data is stored in the control unit. In the state where the “no abnormality” data is not held in the control unit, a safety structure is employed in which charging is not started even if the charging connector 2a is connected to the electric vehicle. On the other hand, if the result of the disconnection check is determined to be “abnormal”, the “abnormal” data is displayed on the display unit 9 or the “abnormal” data is automatically transmitted to the administrator to The safety structure is used to warn of the occurrence of electric shock and avoid electric shock accidents. If the disconnection check result is determined to be “abnormal”, the control unit does not hold the “abnormal” data as described above, so the charging connector 2a is connected to the electric vehicle. Even if it is connected, it has a safety structure that does not start charging.

なお、充電用コネクタ２ａは、略円筒形状であって、その先端付近の側面に取外ボタン２ｂを備え、先端部分には、該取外ボタン２ｂに連動する爪部（図示しない）および充電用接続ピン（２本）、アース線接続ピン（1本）、自動車との情報通信線（１本）の各ピンを備えた本体部２ｄと、該本体部２ｄに対し略「く」字状に折曲した方向に形成された握持部２ｅとから構成されている。該爪部を、自動車側コネクタ（図示しない）又は保持コネクタ３に接続すると、該充電用コネクタ２ａがコネクタと接続状態にあることを示す「接続状態」データが、自動車側制御回路（図示しない）又は自動車用充電スタンドの制御部（図示しない）に保持される。取外ボタン２ｂを押して該爪部とコネクタの接続状態を解除すると、「接続状態」データが、自動車側制御回路（図示しない）又は自動車用充電スタンドの制御部（図示しない）から削除される。   The charging connector 2a has a substantially cylindrical shape and is provided with a removal button 2b on the side surface in the vicinity of the tip. A claw portion (not shown) interlocked with the removal button 2b and a charging button are provided at the tip portion. A main body 2d provided with two pins for connection pins (one), a ground wire connection pin (one), and an information communication line (one) with an automobile, and a substantially "<" shape with respect to the main body 2d It is comprised from the holding part 2e formed in the bent direction. When the claw portion is connected to an automobile side connector (not shown) or the holding connector 3, "connection state" data indicating that the charging connector 2a is in a connected state with the connector is an automobile side control circuit (not shown). Or it is hold | maintained at the control part (not shown) of the charging stand for motor vehicles. When the connection state between the claw and the connector is released by pressing the release button 2b, the “connection state” data is deleted from the vehicle side control circuit (not shown) or the control unit (not shown) of the vehicle charging station.

図３には、保持コネクタ３の説明図を示している。本発明の保持コネクタ３は、図３に示すように、保持面３ｂの角度を変える保持角度可動機構としてその内部に水平軸部３ａを備えている。該水平軸部３ａによって、該保持コネクタ３は上下方向に回動自在に軸支されている。該水平軸部３ａには、保持コネクタ３を上向きに付勢する付勢バネ（図示しない）が設けられており、充電用コネクタ２ａを保持していない時の該保持コネクタ３は、該付勢バネの付勢力により正面を向いている。なお、充電用コネクタ２ａを保持コネクタ３に嵌め込んでいる途中で、不意に下方向に回転しないよう安定して保持するために保持コネクタ３の水平軸部３ａを、保持コネクタ中心よりもやや下側に形成するとともに、保持コネクタ３の上辺部を自動車用充電スタンドの正面パネルの当接部Ｐに当接させる構造とすることが好ましい。   FIG. 3 is an explanatory diagram of the holding connector 3. As shown in FIG. 3, the holding connector 3 of the present invention includes a horizontal shaft portion 3a as a holding angle movable mechanism for changing the angle of the holding surface 3b. The holding connector 3 is pivotally supported by the horizontal shaft portion 3a so as to be rotatable in the vertical direction. The horizontal shaft portion 3a is provided with a biasing spring (not shown) that biases the holding connector 3 upward, and the holding connector 3 when the charging connector 2a is not held is biased. It faces the front due to the biasing force of the spring. In the middle of fitting the charging connector 2a to the holding connector 3, the horizontal shaft portion 3a of the holding connector 3 is slightly lower than the center of the holding connector in order to stably hold it so as not to rotate downward. It is preferable to make it the structure which makes it contact | abut to the contact part P of the front panel of the charging stand for motor vehicles while forming in the side.

該保持コネクタ３は、図４に示すように、充電用コネクタ２ａの抜き差し時には該保持コネクタ３の保持面３ｂに形成した差し込み口３ｃが正面を向く構造とし、図５に示すように、充電用コネクタ２ａの収納時には該保持コネクタ３の差し込み口３ｃが傾斜する構造となっている。すなわち、充電用コネクタ２ａの握持部２ｅが保持コネクタ３に装着されていない状態では、前記付勢バネにより、該保持コネクタ３の保持面側３ｂに形成した差し込み口３ｃが正面を向く構造とし、充電用コネクタ２ａの差し込みをスムーズに行うことができるものである。   As shown in FIG. 4, the holding connector 3 has a structure in which the insertion port 3c formed in the holding surface 3b of the holding connector 3 faces the front when the charging connector 2a is inserted and removed, and as shown in FIG. When the connector 2a is stored, the insertion port 3c of the holding connector 3 is inclined. That is, when the grip portion 2e of the charging connector 2a is not attached to the holding connector 3, the insertion port 3c formed on the holding surface side 3b of the holding connector 3 faces the front by the biasing spring. The charging connector 2a can be smoothly inserted.

充電用コネクタ２ａを保持コネクタ３に差し込んだ後には、充電用コネクタ２ａ及び充電用ケーブル２ｃの自重により該保持コネクタ３を下方向に回転し、保持コネクタ３に正面側より差し込まれた本体部２ｄが斜め下方向を向くことにより、該本体部２ｄに対し略「く」字状に折曲した方向に形成された握持部２ｅが下方向に向くこととなる。これにより充電用コネクタ２ａの差し込み・引き抜き作業性の向上を図ると共に、非使用時に充電用コネクタ２ａが自動車用充電用スタンド１の筐体部１ａの正面側への突出する部分を低減させ、充電用コネクタをコンパクトな収納スペース内に保持可能としている。なお、保持コネクタ３の回転動作は充電コネクタ２ａを下向きに押し下げるものとしてもよい。また、握持部２ｅは自動車用充電スタンド１からの突出が低減されるものであれば、斜め下向きであってもよい。   After the charging connector 2a is inserted into the holding connector 3, the holding connector 3 is rotated downward by the weight of the charging connector 2a and the charging cable 2c, and the main body 2d inserted into the holding connector 3 from the front side. Is directed obliquely downward, so that the grip portion 2e formed in a direction bent in a substantially “<” shape with respect to the main body portion 2d is directed downward. This improves the workability of inserting / extracting the charging connector 2a, and reduces the portion of the charging connector 2a that protrudes to the front side of the casing 1a of the charging stand 1 for the automobile when not in use. Connector can be held in a compact storage space. Note that the rotation operation of the holding connector 3 may be such that the charging connector 2a is pushed downward. Further, the gripping part 2e may be inclined downward as long as the protrusion from the automobile charging stand 1 is reduced.

図３に示すように、本発明の自動車用充電スタンド１の正面部には、充電用コネクタ２ａと充電用ケーブル２ｃを収納するための溝部１０として溝部１０ａ、１０ｂを形成している。前述したように、充電用コネクタ２ａが下向きに回転し、充電用コネクタ２ａの握持部２ｅが充電用スタンド１の筐体部１ａの正面に位置した時に、当該溝部１０ａ、１０ｂに充電用コネクタ２ａと充電用ケーブル２ｃを収納することにより、ボックスの奥行き方向の大きさをさらに抑えつつ、充電用コネクタ２ａおよび充電用ケーブル２ｃをコンパクトに収納可能としている。該溝部は充電用コネクタ２ａの本体部を収納する大径溝部１０ａと充電用ケーブル部分を収納する小径溝部１０ｂとからなっている。大径溝部内１０ａに充電用コネクタ２ａの端部を係止する係止突起１１を形成し、前記保持コネクタ３を上向きに付勢するねじりバネに抗して保持する構造を有している。   As shown in FIG. 3, groove portions 10 a and 10 b are formed as a groove portion 10 for housing the charging connector 2 a and the charging cable 2 c on the front portion of the automobile charging stand 1 of the present invention. As described above, when the charging connector 2a rotates downward and the grip portion 2e of the charging connector 2a is positioned in front of the casing portion 1a of the charging stand 1, the charging connector is inserted into the grooves 10a and 10b. By storing 2a and the charging cable 2c, the charging connector 2a and the charging cable 2c can be stored in a compact manner while further suppressing the size of the box in the depth direction. The groove portion is composed of a large-diameter groove portion 10a for accommodating the main body portion of the charging connector 2a and a small-diameter groove portion 10b for accommodating the charging cable portion. A locking projection 11 for locking the end of the charging connector 2a is formed in the large-diameter groove 10a, and the holding connector 3 is held against a torsion spring that biases upward.

なお、充電用コネクタ２ａと保持コネクタ３との接続が不完全な場合、充電用コネクタ２ａが前記大径溝部１０ａ内に収まらず、充電用コネクタ２ａを保持することができない構造となっている。   When the connection between the charging connector 2a and the holding connector 3 is incomplete, the charging connector 2a does not fit in the large-diameter groove 10a, and the charging connector 2a cannot be held.

なお、上記した実施形態では、保持角度可動機構は水平軸部３ａにより保持コネクタ３を下向きに回転させる構造であるが、充電用コネクタ２ａを保持した時に、保持コネクタ３を水平方向に回転させて保持面の向きを変え、握持部２ｅを充電スタンドからの突出を低減構造としてもよい。   In the above-described embodiment, the holding angle movable mechanism has a structure in which the holding connector 3 is rotated downward by the horizontal shaft portion 3a. However, when the charging connector 2a is held, the holding connector 3 is rotated in the horizontal direction. The direction of the holding surface may be changed, and the gripping portion 2e may have a structure that reduces protrusion from the charging stand.

すなわち、保持コネクタ３を充電スタンド１の正面パネルに保持する軸部が、保持コネクタの充電用コネクタ保持面に対して垂直方向に形成されていて、充電用コネクタ２ａが装着されていない状態では、付勢バネにより、該保持コネクタ３の差し込み口３ｃが正面を向いているが、保持コネクタ３に差し込んだ後に、付勢バネに抗して水平方向に回転させるものとする。このとき時充電スタンド１の正面パネルには充電用コネクタ２ａの本体部２ｄと握持部２ｅに対応する溝部と、溝部内に設けた充電用コネクタ２ａを保持する係止突起を形成しておくものとする。   That is, in a state where the shaft portion that holds the holding connector 3 on the front panel of the charging stand 1 is formed in a direction perpendicular to the charging connector holding surface of the holding connector and the charging connector 2a is not attached, The insertion port 3c of the holding connector 3 is directed to the front by the biasing spring, but after being inserted into the holding connector 3, it is rotated in the horizontal direction against the biasing spring. At this time, the front panel of the charging stand 1 is formed with a groove corresponding to the main body 2d and the gripping part 2e of the charging connector 2a, and a locking projection for holding the charging connector 2a provided in the groove. Shall.

また、充電用コネクタを保持しない状態では、電気自動車用充電スタンドの正面方向に向くように付勢しておくことが好ましい。   Further, in a state where the charging connector is not held, it is preferable to bias the charging connector so as to face the front direction of the charging stand for the electric vehicle.

さらに、正面パネルには充電用接続手段２である充電用コネクタ２ａ等の形状に対応する溝部を形成しておくことが好ましい。   Furthermore, it is preferable to form a groove corresponding to the shape of the charging connector 2a or the like as the charging connecting means 2 on the front panel.

また、保持コネクタ３から自動車用充電スタンド１の内部に雨水が侵入する恐れがあり、特に、該保持コネクタ３を可動式とした場合、図２の隙間S１から保持コネクタ３背面空間へ、雨水が侵入することが想定されるが、本実施形態では、保持コネクタ３背面空間を防水空間Ｂとして樹脂部材等で保持コネクタ３が取付けられた筐体部１ａの背面側を覆う構造とし、また該防水空間に侵入した雨水が、図２の隙間S２から速やかに排出される構造としている。該防水空間を形成する防水カバーの上部には断線チェック用の検出信号線を引き出すための孔部が形成されている。該検出信号線は、充電前に、充電装置と保持コネクタ間のインピーダンスを計測し、充電ケーブルの断線の有無を確認することを目的として、保持コネクタ３内に配線されているものである。ここで、断線等の異常が検出された場合には、異常情報が保持されそれ以降の充電を阻止する安全構造となっている。また、異常情報は表示部に出力され、更に警報やネットワークによる通知を行うシステムとなっている。   Further, there is a risk that rainwater may enter the interior of the vehicle charging stand 1 from the holding connector 3. In particular, when the holding connector 3 is made movable, rainwater enters the space behind the holding connector 3 from the gap S1 in FIG. However, in this embodiment, the back space of the holding connector 3 is defined as a waterproof space B and the back surface of the housing 1a to which the holding connector 3 is attached is covered with a resin member or the like. Rainwater that has entered the space is quickly discharged from the gap S2 in FIG. A hole for drawing out a detection signal line for disconnection check is formed in the upper part of the waterproof cover forming the waterproof space. The detection signal line is wired in the holding connector 3 for the purpose of measuring the impedance between the charging device and the holding connector and confirming whether the charging cable is disconnected before charging. Here, when an abnormality such as a disconnection is detected, the abnormality information is retained, and the safety structure prevents the subsequent charging. In addition, the abnormality information is output to the display unit, and further, a system for performing alarms and notifications via a network.
