以下、本発明の実施形態を図面に基づいて詳細に説明する。以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものでは全くない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary and is not intended to limit the present invention, its applications or its uses.

図１は、本実施形態に係る充電口構造を適用した電気自動車やプラグインハイブリッド車等の電力を用いて走行する車両１を示している。この車両１は、電源部としてのバッテリー３を搭載している。そして、充電口５内に、図示しない外部電源から延びる差込プラグが差し込まれて、前記バッテリー３が充電されるようになっている。 FIG. 1 shows a vehicle 1 that travels by using electric power such as an electric vehicle or a plug-in hybrid vehicle to which the charging port structure according to the present embodiment is applied. This vehicle 1 is equipped with a battery 3 as a power supply unit. Then, a plug extending from an external power source (not shown) is inserted into the charging port 5 to charge the battery 3.

図２及び図３に示すように、前記充電口５は、車体としての左側リアクオータパネル２においてリアドアウインドウの後側部分（従来リアクオータウィンドウが設けられる位置）の外面部に円形に開口され、言い換えると、リアクオータパネル２は内側に凹陥され、その凹陥部が充電口５となっている。図２及び図３に示すように、充電口５の内部には、充電口５の略中心部に充電コネクタ７が収容配置されている。また、充電口５には、充電コネクタ７をその周方向から囲うように充電口照明９としてのＬＥＤが配設されている。充電口照明９は、後述する蓋部１７が開けられたときに点灯して、充電コネクタ７の位置をユーザーに認識させる。また、充電口５内には振動センサ１１及び照度センサ１３が設けられている。振動センサ１１は、充電コネクタ７への差込プラグの抜き差しの際に発生する充電コネクタ７の振動を検出し、その検出信号を後述する制御部１５に出力する。また、照度センサ１３は車外の照度を検出し、検出した照度信号を振動センサ１１と同様に制御部１５に出力する。 As shown in FIGS. 2 and 3, the charging port 5 is circularly opened on the outer surface of the rear portion of the rear door window (the position where the conventional rear quarter window is provided) in the left rear quarter panel 2 as the vehicle body. In other words, the rear quarter panel 2 is recessed inward, and the recessed portion serves as a charging port 5. As shown in FIGS. 2 and 3, a charging connector 7 is housed and arranged in a substantially central portion of the charging port 5 inside the charging port 5. Further, the charging port 5 is provided with an LED as the charging port illumination 9 so as to surround the charging connector 7 from its circumferential direction. The charging port lighting 9 lights up when the lid portion 17, which will be described later, is opened, and makes the user recognize the position of the charging connector 7. Further, a vibration sensor 11 and an illuminance sensor 13 are provided in the charging port 5. The vibration sensor 11 detects the vibration of the charging connector 7 generated when the plug is inserted and removed from the charging connector 7, and outputs the detection signal to the control unit 15 described later. Further, the illuminance sensor 13 detects the illuminance outside the vehicle and outputs the detected illuminance signal to the control unit 15 in the same manner as the vibration sensor 11.

充電口５近くのリアクオータパネル２には、充電口５を開閉する円形の板状の蓋部１７が支持されており、該蓋部１７は充電口５の上端に設けたヒンジ部１９によって支持軸１９ａ周りに上下方向に沿って回動可能にリアクオータパネル２に支持されて、充電口５を開閉するようになっている。図３において２点鎖線で示したように、蓋部１７が閉じられた状態では、充電口５内の充電コネクタ７等が車外に露出せずに、充電口５内に雨水が侵入するのを防止することができる。一方、蓋部１７が開かれた状態では、充電口５内の充電コネクタ７等が車外に露出し、該蓋部１７はその表面が上方に向き、裏面が下方（足元）に向くようになっている。 A circular plate-shaped lid 17 that opens and closes the charging port 5 is supported on the rear quarter panel 2 near the charging port 5, and the lid 17 is supported by a hinge portion 19 provided at the upper end of the charging port 5. The charging port 5 is opened and closed by being supported by the rear quarter panel 2 so as to be rotatable around the shaft 19a in the vertical direction. As shown by the alternate long and short dash line in FIG. 3, when the lid 17 is closed, rainwater does not enter the charging port 5 without exposing the charging connector 7 or the like in the charging port 5 to the outside of the vehicle. Can be prevented. On the other hand, when the lid 17 is opened, the charging connector 7 or the like in the charging port 5 is exposed to the outside of the vehicle, and the front surface of the lid 17 faces upward and the back surface faces downward (foot). ing.

次に、蓋部１７の構成を説明する。以下に示す蓋部１７の上下方向とは、蓋部１７が閉じられた状態での上下方向（車高方向）である。また、左右方向とは、蓋部１７が閉じられた状態での車両１の前後方向であり、車両前方が左側、車両後方が右側である。 Next, the configuration of the lid portion 17 will be described. The vertical direction of the lid portion 17 shown below is a vertical direction (vehicle height direction) in a state where the lid portion 17 is closed. The left-right direction is the front-rear direction of the vehicle 1 with the lid 17 closed, with the front side of the vehicle on the left side and the rear side of the vehicle on the right side.

蓋部１７の裏面の中央部には円形状の平面２１が形成されており、該平面２１には人感センサ２３が配設されている。人感センサ２３は赤外線センサからなり、充電口５の周辺の人を検出し、その検出信号を制御部１５に出力する。また、蓋部１７の裏面には、前記平面２１の外周縁から蓋部１７の外周縁に向かって該蓋部１７の表面側に向かうように傾斜する傾斜面２５が形成されており、言い換えると、傾斜面２５は、該蓋部１７が開かれた状態で蓋部１７の中央側から外周側に向かって上方に向かうように傾斜している。そして、該傾斜面２５には、第１発光部としてのＬＥＤからなる照明用光源（図示せず）を有する足元照明用発光部２７が蓋部１７の外周部に沿うように配設されている。該足元照明用発光部２７は、蓋部１７の傾斜面２５における左右両側部分の２カ所にそれぞれ周方向に連続して円弧状に配置されており、上側及び下側には配置されていない。足元照明用発光部２７は、蓋部１７の裏面に配置されているので、蓋部１７が開かれた状態では下方（図３で示す矢印の方向）に向けて光を照射するようになっている。 A circular flat surface 21 is formed in the central portion of the back surface of the lid portion 17, and a motion sensor 23 is arranged on the flat surface 21. The motion sensor 23 includes an infrared sensor, detects a person around the charging port 5, and outputs the detection signal to the control unit 15. Further, on the back surface of the lid portion 17, an inclined surface 25 is formed which is inclined from the outer peripheral edge of the flat surface 21 toward the outer peripheral edge of the lid portion 17 toward the front surface side of the lid portion 17, in other words. The inclined surface 25 is inclined upward from the central side of the lid portion 17 toward the outer peripheral side in a state where the lid portion 17 is opened. Then, on the inclined surface 25, a foot illumination light emitting portion 27 having an illumination light source (not shown) composed of an LED as a first light emitting portion is arranged along the outer peripheral portion of the lid portion 17. .. The light emitting portions 27 for foot illumination are arranged in an arc shape continuously in the circumferential direction at two locations on the left and right side portions of the inclined surface 25 of the lid portion 17, and are not arranged on the upper side and the lower side. Since the light emitting portion 27 for foot illumination is arranged on the back surface of the lid portion 17, when the lid portion 17 is opened, the light emitting portion 27 is irradiated downward (in the direction of the arrow shown in FIG. 3). There is.

一方、蓋部１７の周囲側部には、バッテリー３の充電状態を示す第２発光部としての表示用発光部３１が設けられている。具体的には、蓋部１７の側面部において表示用発光部３１に対応する部分は透明に形成され、その透明部分の内側（蓋部１７の中央側）に、ＬＥＤからなる表示用光源（図示せず）が設けられている。すなわち表示用発光部３１は、表示用光源からの光を蓋部１７の透明な側面部を透過させることで発光するようになっている。 On the other hand, a light emitting unit 31 for display as a second light emitting unit indicating the charging state of the battery 3 is provided on the peripheral side portion of the lid portion 17. Specifically, a portion of the side surface portion of the lid portion 17 corresponding to the light emitting portion 31 for display is transparently formed, and a display light source composed of an LED is formed inside the transparent portion (center side of the lid portion 17) (FIG. Not shown) is provided. That is, the display light emitting unit 31 emits light by transmitting the light from the display light source through the transparent side surface portion of the lid portion 17.

前記表示用発光部３１は、蓋部１７が開いた状態でその周囲側部における左側、右側及び下側の３カ所に、周囲側部に沿うようにそれぞれ連続して配置されている。また、この表示用発光部３１の表示用光源は、後述するようにバッテリー３の充電状況に応じて発光色が変更されるようになっている。 The display light emitting unit 31 is continuously arranged along the peripheral side portion at three locations on the left side, the right side, and the lower side of the peripheral side portion with the lid portion 17 open. Further, the light emitting color of the display light source of the display light emitting unit 31 is changed according to the charging status of the battery 3 as described later.

図４は、前記足元照明用発光部２７及び表示用発光部３１（表示用光源）を制御するための制御システムを示す。前記のように、車両１は、バッテリー３、人感センサ２３、振動センサ１１、照度センサ１３、足元照明用発光部２７及び表示用発光部３１を有し、これらは制御部１５に接続されている。 FIG. 4 shows a control system for controlling the foot illumination light emitting unit 27 and the display light emitting unit 31 (display light source). As described above, the vehicle 1 has a battery 3, a motion sensor 23, a vibration sensor 11, an illuminance sensor 13, a light emitting unit 27 for foot lighting, and a light emitting unit 31 for display, which are connected to the control unit 15. There is.

バッテリー３の電圧値は制御部１５において検出される。人感センサ２３は、蓋部１７が開けられた状態で、充電口５の周辺に人が存在するか否かを検知し、その信号を制御部１５に出力する。振動センサ１１は、充電コネクタ７への差込プラグの抜き差しの際に発生する充電コネクタ７の振動を検出し、その信号を制御部１５に出力する。照度センサ１３は、車外の照度を検出して、その検出信号を制御部１５に出力する。そして、制御部１５は、入力された前記情報に基づいて、足元照明用発光部２７（照明用光源）及び表示用発光部３１（表示用光源）の発光を制御する。 The voltage value of the battery 3 is detected by the control unit 15. The motion sensor 23 detects whether or not there is a person around the charging port 5 with the lid 17 open, and outputs the signal to the control unit 15. The vibration sensor 11 detects the vibration of the charging connector 7 generated when the plug is inserted and removed from the charging connector 7, and outputs the signal to the control unit 15. The illuminance sensor 13 detects the illuminance outside the vehicle and outputs the detection signal to the control unit 15. Then, the control unit 15 controls the light emission of the foot illumination light emitting unit 27 (illumination light source) and the display light emitting unit 31 (display light source) based on the input information.

ここで、前記制御部１５において表示用発光部３１（表示用光源）を制御するときの動作について図５のフローチャートを参照しながら説明する。まず、最初のステップＳ１０１において、充電コネクタ７の振動により、充電コネクタ７に差込プラグが接続されたか否かを判定する。充電コネクタ７に差込プラグが接続されてバッテリー３の充電が開始し、判定がＹＥＳになると、ステップＳ１０２へ進み、表示用発光部３１を赤色に点灯させる。その後ステップＳ１０３へ進み、バッテリー３の電圧値が所定値以上かどうかを判定する。この判定がＮＯの場合は、バッテリー３の電圧値を継続監視する。バッテリー３の電圧値が所定値以上であるＹＥＳの場合は、ステップＳ１０５へ進み、表示用発光部３１の発光色を緑色に変更させる。そして、ステップＳ１０６へ進み、差込プラグが充電コネクタ７から抜かれたか否かを判定し、ＹＥＳになると、ステップＳ１０７において、表示用発光部３１を消灯させる。 Here, the operation when the control unit 15 controls the display light emitting unit 31 (display light source) will be described with reference to the flowchart of FIG. First, in the first step S101, it is determined whether or not the plug is connected to the charging connector 7 by the vibration of the charging connector 7. When the plug is connected to the charging connector 7 and charging of the battery 3 is started and the determination is YES, the process proceeds to step S102 and the display light emitting unit 31 is lit in red. After that, the process proceeds to step S103, and it is determined whether or not the voltage value of the battery 3 is equal to or higher than a predetermined value. If this determination is NO, the voltage value of the battery 3 is continuously monitored. If YES, the voltage value of the battery 3 is equal to or higher than a predetermined value, the process proceeds to step S105, and the emission color of the display light emitting unit 31 is changed to green. Then, the process proceeds to step S106, and it is determined whether or not the plug has been pulled out from the charging connector 7. If YES, the display light emitting unit 31 is turned off in step S107.

次に、制御部１５による足元照明用発光部２７（照明用光源）の制御動作について図６のフローチャートを参照しながら説明する。ステップＳ２０１において、車外の照度が所定値以下であるか否かを判定する。照度が所定値以下のＹＥＳである場合はステップＳ２０２へ進み、充電口５の周辺に人が検知されたかどうかを判定する。この判定がＹＥＳであれば、足元照明用発光部２７を点灯させる（ステップＳ２０３）。その後ステップＳ２０４へ進み、ステップＳ２０２と同様に充電口５周辺の人の有無を検知し、人が検知されたＹＥＳのときには、ステップＳ２０３に戻る。充電口５の周辺に人が検知されなければ（ステップＳ２０４の判定がＮＯ）、ステップＳ２０５に進み、所定時間（例えば１０秒）が経過したかどうかを判定し、所定時間の経過により判定がＹＥＳになると、ステップＳ２０６において足元照明用発光部２７を消灯させる。 Next, the control operation of the foot illumination light emitting unit 27 (illumination light source) by the control unit 15 will be described with reference to the flowchart of FIG. In step S201, it is determined whether or not the illuminance outside the vehicle is equal to or less than a predetermined value. If the illuminance is YES below a predetermined value, the process proceeds to step S202, and it is determined whether or not a person is detected in the vicinity of the charging port 5. If this determination is YES, the foot illumination light emitting unit 27 is turned on (step S203). After that, the process proceeds to step S204, the presence or absence of a person around the charging port 5 is detected in the same manner as in step S202, and if the number of people is YES, the process returns to step S203. If no person is detected around the charging port 5 (the determination in step S204 is NO), the process proceeds to step S205, it is determined whether or not a predetermined time (for example, 10 seconds) has elapsed, and the determination is YES when the predetermined time has elapsed. Then, in step S206, the light emitting unit 27 for foot illumination is turned off.

したがって、本実施形態によれば、図２及び図３に示すように、充電口５を開閉する蓋部１７は上下方向に沿って回動するようになっており、その蓋部１７が開かれた状態では蓋部１７の裏面は下方を向いている。そして足元照明用発光部２７は、この蓋部１７裏面の傾斜面２５にそれぞれ連続して配置されているので、足元照明用発光部２７から線状に連続した光が下方の足元へ照射され、その光は、充電口５に遮られることなく、しかも傾斜面２５よりも蓋部１７の外周側の広い範囲に拡散して照射されることになる。このことによって、足元照明用発光部２７の光が照射される範囲を広げることができ、さらに、光が点状でなく線状に照射されるので、足元を均一に照射することができる。これらのことにより、ユーザーは足元の確認を十分に行うことができる。さらに、足元照明用発光部２７が位置している傾斜面２５は蓋部１７の裏面外周部に形成されているので、蓋部１７の裏面中央部にスペースを空けて人感センサ２３を配置する平面２１を設けることができる。また、足元照明用発光部２７は蓋部１７の裏面に設けられているので、その蓋部１７が閉じられた状態では、足元照明用発光部２７は外部に露出されない。よって、車両１の意匠性を低下させずに、足元照明用発光部２７を設けることができる。 Therefore, according to the present embodiment, as shown in FIGS. 2 and 3, the lid 17 that opens and closes the charging port 5 rotates along the vertical direction, and the lid 17 is opened. In this state, the back surface of the lid 17 faces downward. Since the foot illumination light emitting unit 27 is continuously arranged on the inclined surface 25 on the back surface of the lid portion 17, linearly continuous light is emitted from the foot illumination light emitting unit 27 to the lower foot. The light is not blocked by the charging port 5, and is diffused and irradiated over a wide range on the outer peripheral side of the lid 17 with respect to the inclined surface 25. As a result, the range of irradiation of the light emitting unit 27 for foot illumination can be expanded, and since the light is irradiated linearly instead of point-shaped, the feet can be uniformly irradiated. By these things, the user can sufficiently confirm the feet. Further, since the inclined surface 25 on which the light emitting portion 27 for foot illumination is located is formed on the outer peripheral portion of the back surface of the lid portion 17, the motion sensor 23 is arranged with a space in the center portion of the back surface of the lid portion 17. A flat surface 21 can be provided. Further, since the foot illumination light emitting portion 27 is provided on the back surface of the lid portion 17, the foot illumination light emitting portion 27 is not exposed to the outside when the lid portion 17 is closed. Therefore, the light emitting unit 27 for foot illumination can be provided without deteriorating the design of the vehicle 1.

また、蓋部１７は、開かれた状態では周囲側部が車両側方に向けられることになり、該周囲側部に沿うように表示用発光部３１が設けられている。このことによって、車両１から様々な方向に離れた場所からも表示用発光部３１の発光を目視することでバッテリー３の充電状況を確認することができる。よって、例えば、家庭のガレージでバッテリー３の充電を行う場合は、長時間の充電であっても車両１に付いた状態で確認する必要がなく、車両１から離れた例えば家屋内からでも充電状況を確認することができる。さらに、表示用発光部３１では、バッテリー３の充電状況が発光色の変更により表示されるので、充電状況を一目で容易に確認することができる。また、表示用発光部３１の光源は、蓋部１７の側面部から離れた中央側の位置に配置されているので、その表示用光源の指向性が低下したものとなり、その分、表示発光部３１をより広い範囲に発光させることができる。 Further, when the lid portion 17 is opened, the peripheral side portion is directed toward the vehicle side, and the display light emitting portion 31 is provided along the peripheral side portion. As a result, the charging status of the battery 3 can be confirmed by visually observing the light emission of the display light emitting unit 31 from places away from the vehicle 1 in various directions. Therefore, for example, when charging the battery 3 in a home garage, it is not necessary to check the state of being attached to the vehicle 1 even if the battery is charged for a long time, and the charging status is charged even from a house away from the vehicle 1, for example. Can be confirmed. Further, since the display light emitting unit 31 displays the charging status of the battery 3 by changing the light emitting color, the charging status can be easily confirmed at a glance. Further, since the light source of the display light emitting unit 31 is arranged at a position on the center side away from the side surface portion of the lid portion 17, the directivity of the display light source is lowered, and the display light emitting unit is correspondingly reduced. 31 can be made to emit light in a wider range.

さらに、充電口５周辺の人の有無を人感センサ２３により検知し、充電口５の周辺に人がいなくなってから所定時間を経過すると足元照明用発光部２７の照明用光源が自動的に消灯されるようになっているので、バッテリー３の充電中での点灯時間を削減でき、充電の効率の低下を防止することができる。 Further, the presence / absence of a person around the charging port 5 is detected by the motion sensor 23, and the lighting light source of the foot lighting light emitting unit 27 is automatically turned off when a predetermined time elapses after there are no people around the charging port 5. Therefore, it is possible to reduce the lighting time during charging of the battery 3 and prevent a decrease in charging efficiency.

また、本実施形態の充電口５は、リアクオータパネル２の上部（従来リアクオータウィンドウが設けられる位置）の外面部に形成されているので、充電口５をユーザーの目線の近くに配置することができ、充電操作がし易くなると共に充電状況の確認が容易になる。 Further, since the charging port 5 of the present embodiment is formed on the outer surface of the upper part of the rear quarter panel 2 (the position where the conventional rear quarter window is provided), the charging port 5 should be arranged near the user's line of sight. This makes it easier to perform charging operations and check the charging status.
