 給電リッドを電動で開閉することが要望されている。しかし、特許文献1のリッド装置では、給電リッドの閉状態で付勢部材によってコネクタリッドを付勢するため、給電リッドを開閉させるために高トルクのモータを使用する必要がある。このようなモータはコストが高いため、特許文献1のリッド装置にはコスト面で改善の余地がある。 There is a demand for electric opening and closing of the power supply lid. However, in the lid device of Patent Document 1, since the connector lid is urged by the urging member when the power supply lid is closed, it is necessary to use a high-torque motor to open and close the power supply lid. Since such a motor is expensive, the lid device of Patent Document 1 has room for improvement in terms of cost.
 本発明は、給電コネクタの防水性を確保でき、リッドを開閉するためのモータの低トルク化によってコストを抑えることができる車両用リッド装置を提供することを課題とする。 An object of the present invention is to provide a vehicle lid device that can secure the waterproofness of the power supply connector and reduce the cost by reducing the torque of the motor for opening and closing the lid.
 本発明は、車体パネルの充電口を取り囲むように車内側に配置される筒状の第1収容部と、前記充電口を塞ぐ閉位置と前記充電口を開放した開位置との間の移動が許容されるように、前記第1収容部内に取り付けられた外側リッドと、前記外側リッドを前記閉位置と前記開位置に移動させるモータを含む駆動機構と、前記第1収容部の軸線に沿って設けられた筒状の周壁を有し、前記周壁の前記充電口側の端が前記第1収容部内に位置する第2収容部と、前記第2収容部内に少なくとも接続口が位置するように、前記第2収容部に取り付けられた給電コネクタと、前記周壁内を通した前記充電口側と前記給電コネクタ側の連通を遮断した閉位置と、この閉位置から前記給電コネクタ側へ回転し、前記充電口側と前記給電コネクタ側を連通させた開位置との間の回転が許容されるように、前記充電口と前記給電コネクタの間に取り付けられた内側リッドと、前記内側リッドを前記閉位置に付勢する付勢部材とを備える車両用リッド装置を提供する。ここで、第1収容部の軸線に沿って設けられた筒状の周壁を有する第2収容部とは、第1収容部の軸線と第2収容部の周壁の軸線とが、平行に延びる構成と、交差する方向に延びる構成の両方が含まれる。 According to the present invention, a cylindrical first accommodation portion arranged inside the vehicle so as to surround a charging port of a vehicle body panel can be moved between a closed position that closes the charging port and an open position that opens the charging port. an outer lid mounted within said first receptacle, a drive mechanism including a motor for moving said outer lid between said closed and said open positions; a second accommodating portion having a cylindrical peripheral wall provided therein, the end of the peripheral wall on the side of the charging port being positioned within the first accommodating portion; A closed position in which communication between the power supply connector attached to the second accommodating portion and the charging port side passing through the peripheral wall and the power supply connector side is cut off; an inner lid attached between the charging port and the power supply connector so as to allow rotation between an open position in which the charging port side and the power supply connector side are communicated; and a biasing member that biases the vehicle lid device. Here, the second accommodating portion having a cylindrical peripheral wall provided along the axis of the first accommodating portion means a configuration in which the axis of the first accommodating portion and the axis of the peripheral wall of the second accommodating portion extend in parallel. and cross-extending configurations.
 モータを含む駆動機構によって充電口を塞ぐ外側リッドが第1収容部内に配置され、第1収容部内に設けられた第2収容部に給電コネクタが配置され、充電口と給電コネクタの間に内側リッドが取り付けられている。よって、たとえ第1収容部内に水が入り込んだとしても、第2収容部内の給電コネクタ側への浸水は内側リッドによって遮断されるため、給電コネクタの防水性を確保できる。 An outer lid that closes the charging port by a drive mechanism including a motor is disposed within the first housing portion, a power supply connector is disposed in a second housing portion provided within the first housing portion, and an inner lid is disposed between the charging port and the power feeding connector. is installed. Therefore, even if water enters the first housing portion, the inner lid blocks the water from entering the power feeding connector side of the second housing portion, so that the waterproofness of the power feeding connector can be ensured.
 内側リッドは付勢部材によって閉位置に付勢されるため、駆動機構は外側リッドのみを電動で開閉させれば良い。よって、駆動用のモータを低トルク化できる。低トルクのモータは高トルクのモータよりも安価であるため、外側リッドを電動で開閉することに伴うコストを抑えることができる。 Since the inner lid is biased to the closed position by the biasing member, the drive mechanism only needs to electrically open and close the outer lid. Therefore, the torque of the driving motor can be reduced. Low torque motors are less expensive than high torque motors, thus reducing the costs associated with electrically opening and closing the outer lid.
 付勢部材によって閉位置に付勢された内側リッドは、車外側からの押圧によって開位置に回転できる。よって、電気自動車を自動充電する場合にも対応できる。具体的には、駆動機構によって外側リッドを回転させて充電口を開放した後、充電プラグを車外側から充電口に挿入し、充電プラグによって内側リッドを押圧して回転させることで、充電プラグを給電コネクタに自動接続できる。充電完了後には、充電プラグを引き抜くことで、内側リッドを付勢部材の付勢力で閉位置に回転させ、外側リッドを駆動機構によって閉位置に回転させることができる。 The inner lid urged to the closed position by the urging member can be rotated to the open position by pressing from the outside of the vehicle. Therefore, it is possible to cope with automatic charging of an electric vehicle. Specifically, after the outer lid is rotated by the drive mechanism to open the charging port, the charging plug is inserted into the charging port from the outside of the vehicle, and the charging plug is pushed and rotated by the inner lid to open the charging plug. Can be automatically connected to the power supply connector. After charging is completed, the inner lid can be rotated to the closed position by the biasing force of the biasing member by pulling out the charging plug, and the outer lid can be rotated to the closed position by the drive mechanism.

 図2から図4を参照すると、内側リッド40は、充電口2と給電コネクタ15の間に取り付けられており、本実施形態では第2収容部22の周壁23内に配置されている。内側リッド40は、周壁23内を通した充電口2側と給電コネクタ15側の連通を遮断した閉位置(図2及び図3参照)と、給電コネクタ15側へ回転して充電口2側と給電コネクタ15側を連通させた開位置(図4参照)との間を、回転可能である。より具体的には、内側リッド40は、隔壁24の開口部24aを塞ぐ閉位置と、開口部24aを開放した開位置との間の回転が許容されるように、開口部24aの開口縁24bに配置されている。図1及び図5を参照すると、内側リッド40は、一対の開閉体41を備える両開き式であり、それぞれ付勢部材45によって閉位置に付勢されている。一対の開閉体41の外周にはシール部42がそれぞれ設けられている。 2 to 4, the inner lid 40 is attached between the charging port 2 and the power supply connector 15, and is arranged within the peripheral wall 23 of the second housing portion 22 in this embodiment. The inner lid 40 has a closed position (see FIGS. 2 and 3) in which communication between the charging port 2 side and the power supply connector 15 side passing through the peripheral wall 23 is cut off, and a closed position (see FIGS. 2 and 3) that rotates toward the power supply connector 15 side to connect the charging port 2 side. It is rotatable between the open position (see FIG. 4) where the power supply connector 15 side is communicated. More specifically, the inner lid 40 is positioned so that the opening edge 24b of the opening 24a is allowed to rotate between a closed position that closes the opening 24a of the partition wall 24 and an open position that opens the opening 24a. are placed in Referring to FIGS. 1 and 5, the inner lid 40 is of a double-opening type having a pair of opening/closing bodies 41, each biased to a closed position by a biasing member 45. As shown in FIG. Seal portions 42 are provided on the outer peripheries of the pair of opening/closing bodies 41, respectively.
 図5及び図8を参照すると、一対の開閉体41はそれぞれ、樹脂によって線対称な形状に成形されており、隔壁24の開口縁24bの対向位置に設けられた取付部24cに取り付けられている。個々の開閉体41は、車長方向Xの中央で隔壁24の開口部24aを2分割した形状よりも一回り小さい。 Referring to FIGS. 5 and 8, the pair of opening/closing members 41 are each formed of resin in a line-symmetrical shape, and are attached to attachment portions 24c provided at opposing positions of the opening edge 24b of the partition wall 24. . Each opening/closing body 41 is one size smaller than the shape obtained by dividing the opening 24a of the partition wall 24 into two at the center in the vehicle length direction X. As shown in FIG.
 個々の開閉体41には、取付部24cの一対の軸受部24e間に位置する一対の取付片41aが設けられている。一対の軸受部24eと一対の取付片41aに1本の回転軸43を貫通させることで、開閉体41が回転可能に取り付けられる。より具体的には、開閉体41は、車高方向Zに延びる回転軸43まわりに、給電コネクタ15側へ水平方向に回転できる。 A pair of mounting pieces 41a positioned between a pair of bearing portions 24e of the mounting portion 24c is provided on each opening/closing body 41. As shown in FIG. The opening/closing body 41 is rotatably attached by passing one rotating shaft 43 through the pair of bearing portions 24e and the pair of mounting pieces 41a. More specifically, the opening/closing body 41 can rotate in the horizontal direction toward the power supply connector 15 around a rotating shaft 43 extending in the vehicle height direction Z. As shown in FIG.
 図1、図5及び図8を参照すると、シール部42は、ゴム製であり、開閉体41を取り囲むように開閉体41の外周に取り付けられている。シール部42は開閉体41の外周から外向きに突出している。一対の開閉体41が閉位置にあるとき、一対のシール部42のうち、取付片41aとは反対側に位置する先端部(対向部分)42aは、互いに当接する。また、一対の開閉体41が閉位置にあるとき、先端部42a以外の外周部42bは、隔壁24の開口縁24bに当接し、開閉体41と隔壁24の開口縁24bとの間をシールする。 1, 5 and 8, the seal part 42 is made of rubber and is attached to the outer circumference of the opening/closing body 41 so as to surround the opening/closing body 41 . The seal portion 42 protrudes outward from the outer periphery of the opening/closing body 41 . When the pair of opening/closing bodies 41 are in the closed position, the tip portions (opposing portions) 42a of the pair of seal portions 42 located on the opposite side of the mounting pieces 41a are in contact with each other. Further, when the pair of opening/closing bodies 41 are in the closed position, the outer peripheral portion 42b other than the tip end portion 42a abuts against the opening edge 24b of the partition wall 24, thereby sealing the gap between the opening/closing body 41 and the opening edge 24b of the partition wall 24. .
 引き続いて図5及び図8を参照すると、付勢部材45は、一対の開閉体41の回転軸43にそれぞれ取り付けられ、開閉体41を閉位置に付勢する。付勢部材45には、キックバネを用いることができる。但し、付勢部材45は、開閉体41を閉位置に付勢できる構成であれば、必要に応じて変更が可能である。 5 and 8, the biasing members 45 are attached to the rotating shafts 43 of the pair of opening/closing bodies 41, respectively, and bias the opening/closing bodies 41 to the closed position. A kick spring can be used for the biasing member 45 . However, the urging member 45 can be changed as necessary as long as it is configured to urge the opening/closing body 41 to the closed position.
 次に、リッド装置10の動作の一例を説明する。 Next, an example of the operation of the lid device 10 will be described.
 充電スタンドの所定位置に電気自動車を停車させて開閉スイッチを操作すると、このスイッチ操作を検出したECUがリッド装置10を開作動させる。これによりモータ36が正転し、モータ36の回転力が駆動軸37を介して歯車38に伝わり、図10において反時計回りに歯車38が回転する。この歯車38の回転力が内歯車部39に伝わることで、図3に示す閉位置の外側リッド30が図2に示す開位置に回転する。 When the electric vehicle is parked at a predetermined position of the charging station and the open/close switch is operated, the ECU detects this switch operation and opens the lid device 10 . As a result, the motor 36 rotates forward, and the rotational force of the motor 36 is transmitted to the gear 38 via the drive shaft 37, causing the gear 38 to rotate counterclockwise in FIG. As the rotational force of the gear 38 is transmitted to the internal gear portion 39, the outer lid 30 in the closed position shown in FIG. 3 rotates to the open position shown in FIG.
 続いて、充電プラグ5が充電口2から差し込まれる。これにより、充電プラグ5の押圧によって、閉位置の開閉体41が付勢部材45の付勢力に抗して図4に示す開位置に回転する。引き続いて充電プラグ5が差し込まれることにより、充電プラグ5が給電コネクタ15の接続口15aに接続され、充電が開始される。 Then, the charging plug 5 is inserted from the charging port 2. As a result, the pressing of the charging plug 5 rotates the open/close body 41 in the closed position to the open position shown in FIG. 4 against the biasing force of the biasing member 45 . By subsequently inserting the charging plug 5, the charging plug 5 is connected to the connection port 15a of the power supply connector 15, and charging is started.
 充電が完了すると、充電プラグ5が充電口2(給電コネクタ15)から引き抜かれる。これにより、一対の開閉体41が付勢部材45の付勢力によって図2に示す閉位置に回転される。また、ECUがリッド装置10を閉作動させる。これによりモータ36が逆転し、モータ36の回転力が駆動軸37を介して歯車38に伝わり、図10において時計回りに歯車38が回転する。この歯車38の回転力が内歯車部39に伝わることで、図2に示す開位置の外側リッド30が図3に示す閉位置に回転する。 When charging is completed, the charging plug 5 is pulled out from the charging port 2 (power supply connector 15). As a result, the pair of opening/closing members 41 are rotated to the closed position shown in FIG. Also, the ECU closes the lid device 10 . As a result, the motor 36 is reversed, and the rotational force of the motor 36 is transmitted to the gear 38 via the drive shaft 37, causing the gear 38 to rotate clockwise in FIG. As the rotational force of the gear 38 is transmitted to the internal gear portion 39, the outer lid 30 in the open position shown in FIG. 2 rotates to the closed position shown in FIG.
 このように構成されたリッド装置10は、以下の特徴を有する。 The lid device 10 configured in this manner has the following features.
 モータ36を含む駆動機構35によって充電口2を塞ぐ外側リッド30が第1収容部21内に配置され、第1収容部21内に設けられた第2収容部22に給電コネクタ15が配置され、充電口2と給電コネクタ15の間に内側リッドが取り付けられている。よって、たとえ第1収容部21内に水が入り込んだとしても、第2収容部22内の給電コネクタ15側への浸水は内側リッド40によって遮断されるため、給電コネクタ15の防水性を確保できる。 An outer lid 30 that closes the charging port 2 by a drive mechanism 35 including a motor 36 is arranged in the first housing portion 21, and the power supply connector 15 is arranged in the second housing portion 22 provided in the first housing portion 21, An inner lid is attached between the charging port 2 and the power supply connector 15 . Therefore, even if water enters the first accommodation portion 21, the inner lid 40 blocks the water from entering the power supply connector 15 side of the second accommodation portion 22, so that the power supply connector 15 is waterproof. .
 内側リッド40は付勢部材45によって閉位置に付勢されるため、駆動機構35は外側リッド30のみを電動で開閉させれば良い。よって、駆動用のモータ36を低トルク化できる。低トルクのモータ36は高トルクのモータよりも安価であるため、外側リッド30を電動で開閉することに伴うコストを抑えることができる。 Since the inner lid 40 is biased to the closed position by the biasing member 45, the driving mechanism 35 only needs to electrically open and close the outer lid 30. Therefore, the torque of the driving motor 36 can be reduced. Since the low torque motor 36 is less expensive than the high torque motor, the costs associated with electrically opening and closing the outer lid 30 can be reduced.
 付勢部材45によって閉位置に付勢された内側リッド40は、車外側からの押圧によって開位置に回転できる。よって、電気自動車を自動充電する場合にも対応できる。具体的には、駆動機構35によって外側リッド30を回転させて充電口2を開放した後、充電プラグ5を充電口2に挿入し、充電プラグ5によって内側リッド40を押圧して回転させることで、充電プラグ5を給電コネクタ15に自動接続できる。また、充電完了後には、充電プラグ5を引き抜くことで、内側リッド40を付勢部材45の付勢力で閉位置に回転させ、外側リッド30を駆動機構35によって閉位置に回転させることができる。 The inner lid 40 biased to the closed position by the biasing member 45 can be rotated to the open position by pressing from the outside of the vehicle. Therefore, it is possible to cope with automatic charging of an electric vehicle. Specifically, after rotating the outer lid 30 by the driving mechanism 35 to open the charging port 2 , the charging plug 5 is inserted into the charging port 2 , and the inner lid 40 is pressed by the charging plug 5 to rotate. , the charging plug 5 can be automatically connected to the power supply connector 15. After charging is completed, the inner lid 40 can be rotated to the closed position by the biasing force of the biasing member 45 by pulling out the charging plug 5 , and the outer lid 30 can be rotated to the closed position by the driving mechanism 35 .
 第2収容部22の周壁23内には隔壁24が設けられ、内側リッド40は隔壁24の開口縁24bに取り付けられている。隔壁23内に取り付けられた内側リッド40は、第1収容部21内に取り付けられた外側リッド30と干渉することはない。よって、2つのリッド30,40の干渉に伴う動作不良の発生を防止できる。 A partition wall 24 is provided inside the peripheral wall 23 of the second housing portion 22 , and the inner lid 40 is attached to the opening edge 24 b of the partition wall 24 . The inner lid 40 attached inside the partition wall 23 does not interfere with the outer lid 30 attached inside the first housing portion 21 . Therefore, it is possible to prevent malfunctions due to interference between the two lids 30 and 40 .
 内側リッド40は、開口部24aの開口縁24bの対向位置に配置された一対の開閉体41を有する。そのため、1枚の開閉体41を用いる場合と比較して、開閉体41の開閉に必要なスペースが小さくなる。よって、第2収容部22を含むリッド装置10全体を小型化できる。 The inner lid 40 has a pair of opening/closing bodies 41 arranged at positions facing the opening edge 24b of the opening 24a. Therefore, the space required for opening and closing the opening/closing body 41 is smaller than when one opening/closing body 41 is used. Therefore, the overall size of the lid device 10 including the second accommodating portion 22 can be reduced.
 一対の開閉体41は、垂直方向(車高方向Z)に延びる回転軸32まわりで水平方向に回転可能である。よって、一対の開閉体41には自重等による負荷が均一に作用するため、一対の開閉体41の開閉動作を安定化できる。 The pair of opening/closing bodies 41 can rotate horizontally around a rotating shaft 32 extending in the vertical direction (vehicle height direction Z). Therefore, since the load due to the weight of the pair of opening/closing bodies 41 is uniformly applied, the opening/closing operation of the pair of opening/closing bodies 41 can be stabilized.
 一対の開閉体41それぞれの外周にはシール部42が設けられている。また、一対の開閉体41が閉位置にあるとき、一対のシール部42の対向部分42aは互いに当接している。また、シール部42は開口部24aの開口縁24bに当接している。よって、第1収容部21内から第2収容部22の隔壁24よりも内側への浸水を大幅に抑制できる。 A seal portion 42 is provided on the outer periphery of each of the pair of opening/closing bodies 41 . Further, when the pair of opening/closing bodies 41 is in the closed position, the opposing portions 42a of the pair of seal portions 42 are in contact with each other. Also, the seal portion 42 is in contact with the opening edge 24b of the opening portion 24a. Therefore, it is possible to greatly suppress the ingress of water from the inside of the first accommodation portion 21 to the inner side of the partition wall 24 of the second accommodation portion 22 .
 給電コネクタ15は内側リッド40の回転範囲外に配置されている。つまり、給電コネクタ15は、開位置の内側リッド40と間隔をあけて位置している。よって、仮に第1収容部21内から第2収容部22の隔壁24よりも内側に浸水が生じたとしても、給電コネクタ15への水の付着を抑制できる。 The power supply connector 15 is arranged outside the rotation range of the inner lid 40 . That is, the power supply connector 15 is spaced apart from the inner lid 40 at the open position. Therefore, even if water enters inside the partition wall 24 of the second accommodation portion 22 from inside the first accommodation portion 21 , adhesion of water to the power supply connector 15 can be suppressed.
 周壁23には第2収容部22の内部と外部を連通させる通水孔23gが設けられている。そのため、仮に第1収容部21内から第2収容部22内の内側リッド40よりも内側に浸水が生じたとしても、水を第2収容部22内に溜めることなく、通水孔23gを通して外部へ流出させることができる。よって、例えば冬場に内側リッド40の縁付近に溜まった水が凍結し、内側リッド40の開閉に支障をきたすことを防止できる。 The peripheral wall 23 is provided with a water passage hole 23g that communicates the inside and outside of the second housing portion 22 with each other. Therefore, even if water enters from inside the first accommodation portion 21 to inside the inner lid 40 inside the second accommodation portion 22, the water does not accumulate in the second accommodation portion 22 and is discharged to the outside through the water flow hole 23g. can be drained to Therefore, it is possible to prevent water accumulated near the edge of the inner lid 40 from freezing in winter, for example, and hindering the opening and closing of the inner lid 40 .
 通水孔23gが下壁部23cの傾斜面23c1の最も低い位置に形成されている。よって、仮に第2収容部22の隔壁24よりも内側に水が入り込んだ場合でも、確実に外部へ流出させることができる。 A water passage hole 23g is formed at the lowest position of the inclined surface 23c1 of the lower wall portion 23c. Therefore, even if water enters inside the partition wall 24 of the second housing portion 22, it can be reliably discharged to the outside.
 外側リッド30が第1収容部21内に回転可能に取り付けられ、駆動軸37、歯車38及び内歯車部39を介して軸受部30dに伝わるモータ36の駆動力によって、外側リッド30が閉位置と開位置に回転する。このように、外側リッド30の回転軸32とは別の駆動軸37の回転によって外側リッド30を回転させるため、回転軸32に駆動力を直接伝えて回転させる場合と比較して、外側リッド30の開閉を安定化できる。 The outer lid 30 is rotatably mounted in the first housing portion 21, and the driving force of the motor 36 transmitted to the bearing portion 30d via the drive shaft 37, the gear 38, and the internal gear portion 39 causes the outer lid 30 to move to the closed position. Rotate to the open position. Since the outer lid 30 is rotated by the rotation of the drive shaft 37 that is separate from the rotating shaft 32 of the outer lid 30, the outer lid 30 can be rotated by directly transmitting the driving force to the rotating shaft 32. opening and closing can be stabilized.
 以下、本発明の他の実施形態並びに変形例を説明するが、これらの説明において、特に言及しない点は第1実施形態と同様である。以下で言及する図面において、第1実施形態と同一の要素には同一の符号を付している。 Other embodiments and modifications of the present invention will be described below, but points not specifically mentioned in these descriptions are the same as in the first embodiment. In the drawings referred to below, the same reference numerals are given to the same elements as in the first embodiment.
(第2実施形態)
 図11から図14は第2実施形態のリッド装置10を示す。このリッド装置10は、内側リッド40を構成する一対の開閉体41を、垂直方向に回転する両開き式とした点で、第1実施形態のリッド装置10と相違する。また、第2実施形態では、第1収容部21の下壁部21dと第2収容部22の下壁部23cとを一体化し、1つの壁で構成した点で、第1実施形態と相違する。
(Second embodiment)
11 to 14 show the lid device 10 of the second embodiment. This lid device 10 differs from the lid device 10 of the first embodiment in that a pair of opening/closing bodies 41 constituting an inner lid 40 are of a double-opening type that rotates in the vertical direction. Further, the second embodiment differs from the first embodiment in that the lower wall portion 21d of the first accommodating portion 21 and the lower wall portion 23c of the second accommodating portion 22 are integrated to form one wall. .
 図12を参照すると、収容部材20の隔壁24には、内側リッド40の一対の開閉体41をそれぞれ取り付ける一対の取付部24cが設けられている。一対の取付部24cは、開口部24aを画定する開口縁24bの車高方向Zに対向する位置に設けられている。個々の取付部24cの基部24dは、隔壁24から突出し、XY平面に沿って延びている。個々の取付部24cの軸受部24eは、基部24dの車長方向Xの両端に設けられ、それぞれYZ平面に沿って延びている。 Referring to FIG. 12, the partition wall 24 of the housing member 20 is provided with a pair of mounting portions 24c for mounting the pair of opening/closing bodies 41 of the inner lid 40, respectively. The pair of mounting portions 24c are provided at positions facing the vehicle height direction Z of the opening edge 24b that defines the opening portion 24a. A base portion 24d of each mounting portion 24c protrudes from the partition wall 24 and extends along the XY plane. The bearing portions 24e of the individual mounting portions 24c are provided at both ends of the base portion 24d in the vehicle length direction X and extend along the YZ plane.
 図11及び図12を参照すると、個々の開閉体41は、車高方向Zの中央で隔壁24の開口部24aを2分割した形状よりも一回り小さい。開閉体41には、取付部24cの一対の軸受部24e間に位置する一対の取付片41aが設けられている。一対の軸受部24eと一対の取付片41aに1本の回転軸43を貫通させることで、開閉体41が回転可能に取り付けられる。より具体的には、開閉体41は、図13に示す閉位置と図14に示す開位置との間を、車長方向X(水平方向)に延びる回転軸43まわりで給電コネクタ15側へ垂直方向に回転できる。 11 and 12, each opening/closing body 41 is slightly smaller than the shape obtained by dividing the opening 24a of the partition wall 24 into two at the center in the vehicle height direction Z. The opening/closing body 41 is provided with a pair of mounting pieces 41a positioned between the pair of bearing portions 24e of the mounting portion 24c. The opening/closing body 41 is rotatably attached by passing one rotating shaft 43 through the pair of bearing portions 24e and the pair of mounting pieces 41a. More specifically, the opening/closing body 41 rotates between the closed position shown in FIG. 13 and the open position shown in FIG. can rotate in any direction.
 このように構成した第2実施形態のリッド装置10では、第1実施形態と同様に、外側リッド30と内側リッド40によって給電コネクタ15の防水性を確保でき、外側リッド30を開閉するためのモータ36の低トルク化によってコストを抑えることができる。また、付勢部材45によって閉位置に付勢された内側リッド40は、車外側からの押圧によって開位置に回転できる。よって、電気自動車を自動充電する場合にも対応できる。 In the lid device 10 of the second embodiment configured as described above, the waterproofness of the power supply connector 15 can be ensured by the outer lid 30 and the inner lid 40 as in the first embodiment, and the motor for opening and closing the outer lid 30 can be operated. 36 can be reduced in torque to keep costs down. Further, the inner lid 40 urged to the closed position by the urging member 45 can be rotated to the open position by pressing from the outside of the vehicle. Therefore, it is possible to cope with automatic charging of an electric vehicle.
 なお、本発明の車両用リッド装置10は、前記実施形態の構成に限定されず、種々の変更が可能である。 It should be noted that the vehicle lid device 10 of the present invention is not limited to the configuration of the above-described embodiment, and various modifications are possible.
 例えば、図15に示すように、内側リッド40は1枚の開閉体のみで構成されてもよい。この場合、内側リッド40は、図示のように開口部24aの上側に取付部24cを設け、水平方向に延びる回転軸43によって、垂直方向に回転可能とすることが好ましい。このようすれば、開口部24aの車高方向Zの下側や車長方向Xの両側に取付部24cを設ける場合と比較して、強い付勢力の付勢部材45を用いることなく、開口部24aを確実に閉塞できるため、第2収容部22の隔壁24よりも内側への浸水を効果的に抑制できる。 For example, as shown in FIG. 15, the inner lid 40 may be composed of only one opening/closing body. In this case, the inner lid 40 is preferably provided with a mounting portion 24c on the upper side of the opening 24a as shown in the drawing, and is rotatable in the vertical direction by a rotating shaft 43 extending in the horizontal direction. In this way, compared to the case where the mounting portions 24c are provided on the lower side of the opening 24a in the vehicle height direction Z and on both sides in the vehicle length direction X, the opening can be adjusted without using the biasing member 45 having a strong biasing force. 24a can be reliably closed, water intrusion to the inner side of the partition wall 24 of the second housing portion 22 can be effectively suppressed.
 第2収容部22の下壁部23cの上面は、傾斜面23c1,23c2を備えることなく、平坦であってもよい。また、下壁部23cには通水孔23gを設けなくてもよい。 The upper surface of the lower wall portion 23c of the second housing portion 22 may be flat without having the inclined surfaces 23c1 and 23c2. Also, the water passage hole 23g may not be provided in the lower wall portion 23c.
 外側リッド30は、収容部材20に対して回転可能に取り付けられる構成に限られず、充電口2を開閉可能な構成であれば、必要に応じて変更が可能である。 The configuration of the outer lid 30 is not limited to a configuration in which it is rotatably attached to the housing member 20, and can be changed as necessary as long as the configuration allows the charging port 2 to be opened and closed.
 第2収容部22は、端壁25側が第1収容部21から突出するようにしたが、端壁25を含む内端側も第1収容部21内に位置していてもよい。 Although the end wall 25 side of the second housing portion 22 protrudes from the first housing portion 21 , the inner end side including the end wall 25 may also be positioned within the first housing portion 21 .
 第1収容部21の周壁21a及び第2収容部22の周壁23は、四角筒状に限られず、四角以上の多角筒状、又は円筒状であってもよく、これらの断面形状は必要に応じて変更が可能である。 The peripheral wall 21a of the first accommodation portion 21 and the peripheral wall 23 of the second accommodation portion 22 are not limited to a square tubular shape, and may be a polygonal tubular shape having a square or more shape, or a cylindrical shape. can be changed by
 内側リッド40は、第2収容部22の外端23hを塞ぐように、第2収容部22の周壁23又は第1収容部21の周壁21aに取り付けられてもよい。 The inner lid 40 may be attached to the peripheral wall 23 of the second accommodation portion 22 or the peripheral wall 21a of the first accommodation portion 21 so as to block the outer end 23h of the second accommodation portion 22 .
