Description

車両の燃料供給用又は充電用のポート構造Port structure for fueling or charging the vehicle
　本発明は、車両の燃料供給用又は充電用のポート構造に関する。 The present invention relates to a port structure for fuel supply or charging of a vehicle.
　ＪＰ１９８７－６１８２４Ａには、リヤフェンダパネルとホイルハウスとをフュエルフィラーベースにより接続して構成された車両の燃料給油部構造が開示されている。 JP1987-61824A discloses a fuel refueling section structure of a vehicle configured by connecting a rear fender panel and a wheel house with a fuel filler base.
　近年、車両の軽量化を目的として、車両の車体表面を構成する外板（アウターパネル）を樹脂により形成することが検討されている。このような場合、外板に設けられる燃料供給用ポート又は充電用ポートも樹脂で形成されることとなる。これらポート及び外板を樹脂で形成する場合、鉄製の部品等におけるスポット溶接は適用することができず、接着剤又は両面テープ等を用いて部品同士を接合する必要がある。このようなポートにおいて燃料供給ノズル又は充電コネクタが外部から接続される際にはポート構成部材に押し付け力等の外力が作用するため、この外力に対して強度を確保するとともにある程度の伸びを確保する必要がある。 In recent years, for the purpose of reducing the weight of a vehicle, it has been studied to form an outer panel (outer panel) constituting the vehicle body surface with resin. In such a case, the fuel supply port or the charging port provided on the outer plate is also made of resin. When these ports and outer plates are made of resin, spot welding on iron parts and the like cannot be applied, and it is necessary to join the parts together using an adhesive or double-sided tape. When the fuel supply nozzle or the charging connector is connected from the outside in such a port, an external force such as a pressing force acts on the port component, so that the strength is secured against this external force and a certain degree of elongation is secured. There is a need.
　ＪＰ１９８７－６１８２４Ａにおいては、車両の外板等を樹脂により形成することは考慮されておらず、樹脂製のポート構造における強度等について検討がなされていない。 In JP1987-61824A, the formation of the outer panel of the vehicle from resin is not considered, and the strength of the resin port structure is not examined.
　本発明は、車両の燃料供給用又は充電用のポートを樹脂により構成する場合において、適度な強度及び伸びを有するポート構造を提供することを目的とする。 An object of the present invention is to provide a port structure having appropriate strength and elongation when a port for fuel supply or charging of a vehicle is made of resin.
　本発明の一態様によれば、車両の燃料供給用又は充電用のポート構造が提供される。このポート構造は、車体表面の一部を構成する外板部と、外板部から車体内側に延設される側壁と、側壁から当該側壁により囲われる内側空間側へと延設されるとともに、開口を有する底板と、から構成される樹脂製の外板と、底板の表面側に連結され、開口を通じて車体内側に入り込むポート部材と、ポート部材に設けられた燃料供給口又は充電コネクタと、外板の裏面に取り付けられ外板を補強する樹脂製の補強板と、を備える。補強板は、外板部に沿って延設される外板補強部と、外板補強部から側壁に沿って延設される側壁補強部と、側壁補強部から底板に沿って延設されるとともにポート部材を通過させる開口を有する底板補強部と、を備えている。外板補強部及び底板補強部の少なくとも一方には、外板の裏面に当接することにより外板と補強板との間隔を規定する突起が形成されている。外板部と外板補強部、及び底板と底板補強部は、接着剤により接着されている。 According to one aspect of the present invention, a port structure for fuel supply or charging of a vehicle is provided. This port structure extends from the outer plate portion forming a part of the vehicle body surface, the side wall extending from the outer plate portion to the inside of the vehicle body, and from the side wall to the inner space side surrounded by the side wall. A resin outer plate composed of a bottom plate having an opening, a port member connected to the surface side of the bottom plate and entering the inside of the vehicle body through the opening, a fuel supply port or a charging connector provided on the port member, and the outside. It is provided with a resin reinforcing plate attached to the back surface of the plate to reinforce the outer plate. The reinforcing plate is extended along the outer plate portion, the outer plate reinforcing portion extending along the outer plate portion, the side wall reinforcing portion extending from the outer plate reinforcing portion along the side wall, and the reinforcing plate extending from the side wall reinforcing portion along the bottom plate. It also includes a bottom plate reinforcing portion having an opening through which the port member passes. At least one of the outer plate reinforcing portion and the bottom plate reinforcing portion is formed with protrusions that define the distance between the outer plate and the reinforcing plate by abutting against the back surface of the outer plate. The outer plate portion and the outer plate reinforcing portion, and the bottom plate and the bottom plate reinforcing portion are adhered by an adhesive.

　以下、図面を参照して、本発明の実施形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　＜第１実施形態＞
　図１は、第１実施形態による充電用ポート１０を備える車両１００の斜視図である。 <First Embodiment>
FIG. 1 is a perspective view of a vehicle 100 including a charging port 10 according to the first embodiment.
　図１に示す車両１００は、バッテリの充電電力に基づいて走行する電気自動車である。車両１００の車体表面を構成する外板（アウターパネル）２０は、車両１００を軽量化するため、樹脂により形成されている。例えば、本実施形態の車両１００では、車両１００の前方側面を構成するフロントフェンダ２及び後方側面を構成するリアフェンダ（図示省略）を構成する外板２０が樹脂製となっている。 The vehicle 100 shown in FIG. 1 is an electric vehicle that travels based on the charging power of the battery. The outer panel (outer panel) 20 constituting the vehicle body surface of the vehicle 100 is made of resin in order to reduce the weight of the vehicle 100. For example, in the vehicle 100 of the present embodiment, the front fender 2 forming the front side surface of the vehicle 100 and the outer plate 20 forming the rear fender (not shown) forming the rear side surface are made of resin.
　車両１００のフロントフェンダ２を構成する外板２０には、バッテリを充電する際に使用される充電用ポート１０が設けられている。 The outer plate 20 constituting the front fender 2 of the vehicle 100 is provided with a charging port 10 used when charging the battery.
　図２は、蓋部材４を開いた状態における充電用ポート１０の概略構成図である。 FIG. 2 is a schematic configuration diagram of the charging port 10 in a state where the lid member 4 is open.
　図２に示すように、充電用ポート１０は、フロントフェンダ２を構成する外板２０の一部を窪ませて形成された空間内に、充電コネクタ３を備えている。充電コネクタ３は、充電スタンド等に配置された充電装置の電力供給コネクタと接続可能に構成されている。車両１００の充電コネクタ３と充電装置の電力供給コネクタとが接続されることで、車両１００のバッテリが充電される。 As shown in FIG. 2, the charging port 10 includes a charging connector 3 in a space formed by recessing a part of the outer plate 20 constituting the front fender 2. The charging connector 3 is configured to be connectable to a power supply connector of a charging device arranged in a charging stand or the like. The battery of the vehicle 100 is charged by connecting the charging connector 3 of the vehicle 100 and the power supply connector of the charging device.
　なお、充電用ポート１０の入口部分となる、フロントフェンダ２（外板２０）の開口には、ポートを開閉するための蓋部材４（リッド）が開閉自在に配置されている。蓋部材４の車両後方端部には蓋部材４を外板２０に対して回動可能に固定するヒンジ部材４Ａが設けられており、蓋部材４の車両前方端部には後述するポート部材４０の本体部４１（図３参照）の内側に設けられたロック機構１１に対して係合可能な係合部４Ｂが設けられている。蓋部材４を閉じて充電用ポート１０を閉塞すると、ロック機構１１と係合部４Ｂとが係合状態となる。ロック機構１１と係合部４Ｂとの係合状態はドライバ等のアンロック操作により解除可能となっており、図２はロック機構１１と係合部４Ｂとがアンロックされて蓋部材４が開放された状態を示している。 A lid member 4 (lid) for opening and closing the port is arranged so as to be openable and closable in the opening of the front fender 2 (outer plate 20), which is the entrance portion of the charging port 10. A hinge member 4A for rotatably fixing the lid member 4 to the outer plate 20 is provided at the vehicle rear end of the lid member 4, and a port member 40 described later is provided at the vehicle front end of the lid member 4. An engaging portion 4B that can be engaged with the lock mechanism 11 provided inside the main body portion 41 (see FIG. 3) is provided. When the lid member 4 is closed and the charging port 10 is closed, the lock mechanism 11 and the engaging portion 4B are in an engaged state. The engaged state between the lock mechanism 11 and the engaging portion 4B can be released by an unlocking operation such as a driver. In FIG. 2, the locking mechanism 11 and the engaging portion 4B are unlocked and the lid member 4 is opened. It shows the state of being done.
　次に、図３～図５を参照して、充電用ポート１０の詳細について説明する。図３は、充電用ポート１０の縦方向（車両上下方向）の断面図である。図４は、充電用ポート１０を構成する補強板３０の正面図である。図５は、図３の領域Ｒの部分を拡大した拡大図である。 Next, the details of the charging port 10 will be described with reference to FIGS. 3 to 5. FIG. 3 is a cross-sectional view of the charging port 10 in the vertical direction (vertical direction of the vehicle). FIG. 4 is a front view of the reinforcing plate 30 constituting the charging port 10. FIG. 5 is an enlarged view of a portion of the region R in FIG.
　図３に示すように、フロントフェンダ２を構成する外板２０は、その一部が車体内側に凹設されることで、充電用ポート１０としての空間を形成している。外板２０は、ポリプロピレン等の樹脂により形成されている。 As shown in FIG. 3, a part of the outer plate 20 constituting the front fender 2 is recessed inside the vehicle body to form a space as a charging port 10. The outer plate 20 is made of a resin such as polypropylene.
　外板２０は、外板部２１と、外板部２１から車体内側に入り込む側壁２２と、側壁２２から縦方向に延在する底板２３と、を備えている。この外板２０は、樹脂製の一枚板から構成された一体的な構造物である。 The outer plate 20 includes an outer plate portion 21, a side wall 22 that enters the inside of the vehicle body from the outer plate portion 21, and a bottom plate 23 that extends vertically from the side wall 22. The outer plate 20 is an integral structure made of a single resin plate.
　外板部２１は、フロントフェンダ２等の車体表面の一部を構成する部材である。外板部２１は、充電用ポート１０の入口部位としての略矩形状の開口２１Ａを有している。 The outer plate portion 21 is a member that constitutes a part of the vehicle body surface such as the front fender 2. The outer plate portion 21 has a substantially rectangular opening 21A as an inlet portion of the charging port 10.
　側壁２２は、外板部２１の開口端から車体内側、つまり車体内外方向（車両幅方向）に延設されている。側壁２２は、充電用ポート１０の内周壁を規定する部材であって、上側壁、下側壁、前側壁、及び後側壁が一体的に形成された略筒状の壁部材である。 The side wall 22 extends from the open end of the outer plate portion 21 to the inside of the vehicle body, that is, the vehicle body inside / outside direction (vehicle width direction). The side wall 22 is a member that defines the inner peripheral wall of the charging port 10, and is a substantially tubular wall member in which an upper side wall, a lower side wall, a front side wall, and a rear side wall are integrally formed.
　底板２３は、側壁２２の内側端部に形成される壁部材である。底板２３は、外板２０の底面を構成する部位であって、側壁２２から当該側壁２２により囲われる内側空間側へと延設されている。底板２３には、車体内外方向に貫通する貫通孔としての開口２３Ａが形成されている。この底板２３には、ポート部材４０が取り付けられる。 The bottom plate 23 is a wall member formed at the inner end of the side wall 22. The bottom plate 23 is a portion constituting the bottom surface of the outer plate 20, and extends from the side wall 22 to the inner space side surrounded by the side wall 22. The bottom plate 23 is formed with an opening 23A as a through hole that penetrates in and out of the vehicle body. A port member 40 is attached to the bottom plate 23.
　ポート部材４０は、ポリプロピレン等の樹脂により形成された有底筒状の部材である。ポート部材４０は、車体外側面が開口する箱状の本体部４１と、本体部４１の先端から拡大するように形成された鍔状のフランジ部４２とから構成されている。 The port member 40 is a bottomed tubular member made of a resin such as polypropylene. The port member 40 is composed of a box-shaped main body 41 having an opening on the outer surface of the vehicle body and a flange-shaped flange 42 formed so as to expand from the tip of the main body 41.
　ポート部材４０は、フランジ部４２が外板２０の底板２３の表面側端面（外側面）に連結された状態で、本体部４１が底板２３の開口２３Ａを通じて車体内側に入り込むように配置されている。フランジ部４２と底板２３とは、接着剤により結合されてもよいし、係合突起と係合受部を用いた機械的係合手段により結合されてもよい。また、両部材をボルト及びナットにより連結してもよい。 The port member 40 is arranged so that the main body 41 enters the inside of the vehicle body through the opening 23A of the bottom plate 23 in a state where the flange portion 42 is connected to the surface side end surface (outer surface) of the bottom plate 23 of the outer plate 20. .. The flange portion 42 and the bottom plate 23 may be connected by an adhesive, or may be connected by a mechanical engaging means using an engaging protrusion and an engaging receiving portion. Further, both members may be connected by bolts and nuts.
　ポート部材４０の本体部４１の底面には車体内外方向に貫通する開口４１Ａが形成されており、この開口４１Ａを通じて、上述した充電コネクタ３が充電用ポート１０内に位置するように配置される。充電コネクタ３は、ポート部材４０より車体内側に存在するシャシ等の車体構造物に固定された状態で、コネクタ端面が車体外側に臨むように配置されている。本実施形態では、ポート部材４０と充電コネクタ３とは直接的に連結されておらず、充電コネクタ３の外周面とポート部材４０の開口４１Ａとの間には、ゴム製のシール部材（図示省略）が配置されている。なお、充電コネクタ３は、車両１００に搭載されたバッテリ５と電気的に連結されている。 An opening 41A penetrating in and out of the vehicle body is formed on the bottom surface of the main body 41 of the port member 40, and the charging connector 3 described above is arranged so as to be located in the charging port 10 through the opening 41A. The charging connector 3 is arranged so that the end face of the connector faces the outside of the vehicle body while being fixed to the vehicle body structure such as a chassis existing inside the vehicle body from the port member 40. In the present embodiment, the port member 40 and the charging connector 3 are not directly connected, and a rubber sealing member (not shown) is provided between the outer peripheral surface of the charging connector 3 and the opening 41A of the port member 40. ) Is placed. The charging connector 3 is electrically connected to the battery 5 mounted on the vehicle 100.
　本実施形態では、充電用ポート１０は、樹脂製の外板２０等により構成されているため、充電コネクタ３に充電装置の電力供給コネクタを装着する場合、又は蓋部材４を閉じる場合に、外板２０の底板２３等に押し付け力等の外力が作用し、外板２０のみの構成では当該外板２０が大きく変形してしまうおそれがある。そこで、充電用ポート１０の一部を構成する外板２０の強度や伸びを適切なものとするため、外板２０の裏面には補強板３０が取り付けられている。 In the present embodiment, since the charging port 10 is composed of a resin outer plate 20 or the like, it is outside when the power supply connector of the charging device is attached to the charging connector 3 or when the lid member 4 is closed. An external force such as a pressing force acts on the bottom plate 23 or the like of the plate 20, and the outer plate 20 may be significantly deformed if only the outer plate 20 is configured. Therefore, in order to make the strength and elongation of the outer plate 20 forming a part of the charging port 10 appropriate, a reinforcing plate 30 is attached to the back surface of the outer plate 20.
　図３及び図４に示すように、補強板３０は、ポリプロピレン等の樹脂により形成された部材であって、外板２０を補強するための部材である。この補強板３０も、外板２０と同様に、樹脂製の一枚板から構成された一体的な構造物である。 As shown in FIGS. 3 and 4, the reinforcing plate 30 is a member formed of a resin such as polypropylene, and is a member for reinforcing the outer plate 20. Like the outer plate 20, the reinforcing plate 30 is also an integral structure made of a single resin plate.
　補強板３０は、外板２０の外板部２１を補強する外板補強部３１と、外板２０の側壁２２を補強する側壁補強部３２と、外板２０の底板２３を補強する底板補強部３３と、を備える。 The reinforcing plate 30 includes an outer plate reinforcing portion 31 that reinforces the outer plate portion 21 of the outer plate 20, a side wall reinforcing portion 32 that reinforces the side wall 22 of the outer plate 20, and a bottom plate reinforcing portion that reinforces the bottom plate 23 of the outer plate 20. 33 and.
　外板補強部３１は、外板２０の外板部２１に沿って延設された枠部材として形成されている。 The outer plate reinforcing portion 31 is formed as a frame member extending along the outer plate portion 21 of the outer plate 20.
　側壁補強部３２は、外板補強部３１の内周端から車体内側に入り込むように、外板２０の側壁２２に沿って延設されている。側壁補強部３２は、上側壁、下側壁、前側壁、及び後側壁が一体的に形成された略筒状の壁部材である。 The side wall reinforcing portion 32 extends along the side wall 22 of the outer plate 20 so as to enter the inside of the vehicle body from the inner peripheral end of the outer plate reinforcing portion 31. The side wall reinforcing portion 32 is a substantially tubular wall member in which an upper side wall, a lower side wall, a front side wall, and a rear side wall are integrally formed.
　底板補強部３３は、側壁補強部３２の内側端から底板２３に沿って延設される底面である。底板補強部３３には、ポート部材４０を通過させる貫通孔としての開口３３Ａが形成されている。 The bottom plate reinforcing portion 33 is a bottom surface extending from the inner end of the side wall reinforcing portion 32 along the bottom plate 23. The bottom plate reinforcing portion 33 is formed with an opening 33A as a through hole through which the port member 40 passes.
　図３及び図５に示すように、外板２０と補強板３０とは、外板部２１と外板補強部３１との間、及び底板２３と底板補強部３３との間に塗布された接着剤により相互に接着される。このように、外板部２１と外板補強部３１とは第１の接着層５１を介して密着し、底板２３と底板補強部３３とは第２の接着層５２により密着する。 As shown in FIGS. 3 and 5, the outer plate 20 and the reinforcing plate 30 are adhered to each other by being applied between the outer plate portion 21 and the outer plate reinforcing portion 31 and between the bottom plate 23 and the bottom plate reinforcing portion 33. They are adhered to each other by the agent. In this way, the outer plate portion 21 and the outer plate reinforcing portion 31 are brought into close contact with each other via the first adhesive layer 51, and the bottom plate 23 and the bottom plate reinforcing portion 33 are brought into close contact with each other through the second adhesive layer 52.
　外板２０と補強板３０とを接着する第１、第２の接着層５１，５２（接着剤）の厚さは、外板２０の強度及び伸びを規定する上で重要な要素である。例えば、第１及び第２の接着層５１，５２が薄くなりすぎると、外板２０と補強板３０との間隔が小さくなるため、電力供給コネクタ接続時等に作用する外力の入力に対してポート周りの外板２０の強度は増加するものの、外板２０の伸びが低下し、大きな外力が加わるとポート構成部材が塑性変形したりするおそれがある。その一方で、第１及び第２の接着層５１，５２が厚くなりすぎると、外板２０と補強板３０との間隔が大きくなるため、充電時等における外力の入力に対してポート周りの外板２０の伸びが大きくなり、電力供給コネクタを充電コネクタ３に接続しにくくなるおそれがある。 The thickness of the first and second adhesive layers 51 and 52 (adhesive) that bond the outer plate 20 and the reinforcing plate 30 is an important factor in defining the strength and elongation of the outer plate 20. For example, if the first and second adhesive layers 51 and 52 become too thin, the distance between the outer plate 20 and the reinforcing plate 30 becomes smaller, so that the port receives an external force input that acts when the power supply connector is connected. Although the strength of the surrounding outer plate 20 increases, the elongation of the outer plate 20 decreases, and when a large external force is applied, the port constituent members may be plastically deformed. On the other hand, if the first and second adhesive layers 51 and 52 become too thick, the distance between the outer plate 20 and the reinforcing plate 30 becomes large, so that the outside around the port is exposed to the input of external force during charging or the like. The elongation of the plate 20 becomes large, and there is a possibility that it becomes difficult to connect the power supply connector to the charging connector 3.
　そこで、本実施形態では接着剤厚さを適度な厚さとすることを目的として、補強板３０に、外板２０と補強板３０との間隔を規定する間隔調整部材としての突起３４が形成されている。より具体的には、補強板３０の外板補強部３１の表面に、外板部２１の裏面に当接することにより外板２０と補強板３０との間隔を略一定間隔に規定する突起３４が形成されている。一方、外板２０は、補強板３０の突起３４と対向する部位が平坦面形状として形成されており、当該突起３４と係合又は嵌合するような部位を有しない構成となっている。 Therefore, in the present embodiment, for the purpose of making the adhesive thickness an appropriate thickness, the reinforcing plate 30 is formed with a protrusion 34 as an interval adjusting member that defines the distance between the outer plate 20 and the reinforcing plate 30. There is. More specifically, on the surface of the outer plate reinforcing portion 31 of the reinforcing plate 30, a protrusion 34 that defines the distance between the outer plate 20 and the reinforcing plate 30 at a substantially constant interval by contacting the back surface of the outer plate portion 21 is provided. It is formed. On the other hand, the outer plate 20 is formed so that the portion of the reinforcing plate 30 facing the protrusion 34 has a flat surface shape and does not have a portion that engages or fits with the protrusion 34.
　図４に示すように、突起３４は、外板補強部３１の表面に複数形成されており、本実施形態では例えば４つ形成されている。これら４つの突起３４は、補強板３０の開口３３Ａの周囲に沿って並設されており、矩形状の開口３３Ａの４つの角部分に対応する位置にそれぞれ配置されている。これら突起３４の配置は、図４の配置に限らず、任意の位置に設定されてよい。また、突起３４は、開口３３Ａを取り囲むような一本のライン状の突起として構成されてもよい。 As shown in FIG. 4, a plurality of protrusions 34 are formed on the surface of the outer plate reinforcing portion 31, and in the present embodiment, for example, four are formed. These four protrusions 34 are arranged side by side along the periphery of the opening 33A of the reinforcing plate 30, and are arranged at positions corresponding to the four corners of the rectangular opening 33A. The arrangement of these protrusions 34 is not limited to the arrangement shown in FIG. 4, and may be set at any position. Further, the protrusion 34 may be configured as a single line-shaped protrusion that surrounds the opening 33A.
　突起３４は、外板補強部３１上であれば、当該外板補強部３１の先端寄りの位置に形成されてもよいし、先端よりも側壁補強部３２寄りの位置に形成されてもよい。図５に示すように、突起３４を側壁補強部３２寄りの位置に形成する場合には、突起３４が補強板３０自体の部材中心により近い位置に配置されることとなるため、補強板３０と外板２０との間隔を維持しやすい構成となる。 The protrusion 34 may be formed at a position closer to the tip of the outer plate reinforcing portion 31 as long as it is on the outer plate reinforcing portion 31, or may be formed at a position closer to the side wall reinforcing portion 32 than the tip. As shown in FIG. 5, when the protrusion 34 is formed at a position closer to the side wall reinforcing portion 32, the protrusion 34 is arranged at a position closer to the member center of the reinforcing plate 30 itself. The configuration is such that the distance from the outer plate 20 can be easily maintained.
　さらに、図５に示すように、突起３４は、縦方向断面が円弧状に湾曲した形状の突起として形成されている。また、充電用ポート１０周りの外板２０は、一点鎖線ｒ1で示すように、縦方向になだらかに湾曲するように形成されている。このように、なだらかに湾曲する外板２０の外板部２１の裏面に当接する突起３４は、当該突起３４の曲率が外板２０（外板部２１）の曲率よりも大きくなるように構成されている。このような曲面を持つ山形状の突起３４によれば、突起３４を外板部２１の裏面に滑らかに当接させることができ、当接部分における外板２０表面の外観に悪影響を与えることがない。さらに、突起３４が外板２０に対して線接触しやすく、補強板３０と外板２０との間隔を維持しやすい構成となる。 Further, as shown in FIG. 5, the protrusion 34 is formed as a protrusion having a shape in which the vertical cross section is curved in an arc shape. The outer plate 20 around the charging port 10, as shown by the dashed line r 1, is formed so as to gently curved in the longitudinal direction. In this way, the protrusion 34 that abuts on the back surface of the outer plate portion 21 of the outer plate 20 that is gently curved is configured so that the curvature of the protrusion 34 is larger than the curvature of the outer plate 20 (outer plate portion 21). ing. According to the mountain-shaped protrusion 34 having such a curved surface, the protrusion 34 can be smoothly brought into contact with the back surface of the outer plate portion 21, and the appearance of the surface of the outer plate 20 at the contact portion may be adversely affected. Absent. Further, the protrusions 34 are easily line-contacted with the outer plate 20, and the distance between the reinforcing plate 30 and the outer plate 20 is easily maintained.
　本実施形態では、外板２０と補強板３０との間に間隔調整部材としての突起３４が介在することにより、外板２０と補強板３０との間を所定の間隔に維持することができ、補強板３０を外板２０に固定する接着剤（接着層）の厚さを適切な厚さとすることができる。なお、外板２０の側壁２２と補強板３０の側壁補強部３２との間の空間は、外板部２１と外板補強部３１との間の空間、及び底板２３と底板補強部３３との間の空間とにそれぞれ連通している。そのため、外板２０と補強板３０との間に接着剤を多めに塗布したとしても、余剰の接着剤が側壁２２と側壁補強部３２との間の空間に流れ込むようになる。このように、側壁２２と側壁補強部３２との間の空間は、余剰な接着剤を回収するための接着剤収容室として機能する。 In the present embodiment, the protrusion 34 as an interval adjusting member is interposed between the outer plate 20 and the reinforcing plate 30, so that the distance between the outer plate 20 and the reinforcing plate 30 can be maintained at a predetermined distance. The thickness of the adhesive (adhesive layer) for fixing the reinforcing plate 30 to the outer plate 20 can be set to an appropriate thickness. The space between the side wall 22 of the outer plate 20 and the side wall reinforcing portion 32 of the reinforcing plate 30 is the space between the outer plate portion 21 and the outer plate reinforcing portion 31, and the space between the bottom plate 23 and the bottom plate reinforcing portion 33. It communicates with the space between them. Therefore, even if a large amount of adhesive is applied between the outer plate 20 and the reinforcing plate 30, excess adhesive will flow into the space between the side wall 22 and the side wall reinforcing portion 32. In this way, the space between the side wall 22 and the side wall reinforcing portion 32 functions as an adhesive accommodating chamber for collecting excess adhesive.
　本実施形態では、上述したように外板２０と補強板３０とを第１及び第２の接着層５１，５２により接着しているが、このような接着方法を採用する場合、外板２０の線膨張係数と補強板３０の線膨張係数とが大きく異なると、外気の温度状態によっては部品の熱膨張差が発生し、外板２０等での接着箇所で歪が大きくなり、外観異常が発生するおそれがある。 In the present embodiment, as described above, the outer plate 20 and the reinforcing plate 30 are bonded by the first and second adhesive layers 51 and 52. However, when such an bonding method is adopted, the outer plate 20 is bonded. If the coefficient of linear expansion and the coefficient of linear expansion of the reinforcing plate 30 are significantly different, a difference in thermal expansion of the parts will occur depending on the temperature state of the outside air, and distortion will increase at the bonded portion of the outer plate 20 or the like, resulting in an abnormal appearance. There is a risk of
　そこで、以下の表１に示すように、外板２０の材質及び補強板３０の材質を異ならせた比較例、及び実施例１～５に関し、それぞれの外観について検討した。比較例は、外板の材質がポリプロピレンで、補強板の材質がスチール鋼である例である。一方、実施例１～５の外板２０及び補強板３０の材質において、ＰＰはポリプロピレンを意味しており、括弧内に記載されているＧＦ３０、ＴＤ３５はポリプロピレンに添加されたフィラーを意味している。ＧＦ３０はポリプロピレンに対する重量パーセントが３０％のガラス繊維を意味しており、ＴＤ３５はポリプロピレンに対する重量パーセントが３５％のタルクを意味している。 Therefore, as shown in Table 1 below, the appearances of Comparative Examples in which the material of the outer plate 20 and the material of the reinforcing plate 30 were different, and Examples 1 to 5 were examined. A comparative example is an example in which the material of the outer plate is polypropylene and the material of the reinforcing plate is steel. On the other hand, in the materials of the outer plates 20 and the reinforcing plates 30 of Examples 1 to 5, PP means polypropylene, and GF30 and TD35 described in parentheses mean fillers added to polypropylene. .. GF30 means glass fiber with a weight percent of 30% to polypropylene, and TD35 means talc with a weight percent of 35% to polypropylene.

　表１に示す比較例の場合には、外板と補強板の線膨張係数の差に起因して、外観に不良が発生することが確認された。しかしながら、外板２０及び補強板３０の両方を樹脂により形成した実施例１～５では、車両１００がさらされる一般的な外気の温度範囲において、外板２０と補強板３０の線膨張係数の差に起因する外観不良はほぼ認められなかった。これら実施例１～５による知見及び種々の実験等を経た結果、線膨張係数の差に起因する外観不良を抑制するという観点においては、外板２０の線膨張係数と補強板３０の線膨張係数との差の絶対値は４０×１０-6／℃以下であることが好ましい。 In the case of the comparative example shown in Table 1, it was confirmed that a defect occurred in the appearance due to the difference in the coefficient of linear expansion between the outer plate and the reinforcing plate. However, in Examples 1 to 5 in which both the outer plate 20 and the reinforcing plate 30 are formed of resin, the difference in linear expansion coefficient between the outer plate 20 and the reinforcing plate 30 in the general outside air temperature range to which the vehicle 100 is exposed. Almost no appearance defects due to the above were observed. As a result of the findings from Examples 1 to 5 and various experiments, etc., from the viewpoint of suppressing the appearance defect caused by the difference in the linear expansion coefficient, the linear expansion coefficient of the outer plate 20 and the linear expansion coefficient of the reinforcing plate 30 The absolute value of the difference from is preferably 40 × 10 -6 / ° C. or less.
　なお、これら実施例１～５については、外板２０に補強板３０を取り付けた場合におけるポート構造部材の強度についても検討している。樹脂製の外板２０に樹脂製の補強板３０と取り付けることで、ポート構造部材の強度は基本的に確保されていることが確認された。但し、実施例１、３、４に示すように、ガラス繊維等の強化繊維、又はタルクを含有したポリプロピレン等の樹脂により補強板３０を形成した場合に、特に強度が良好であった。これら実施例１～５による知見及び種々の実験等を経た結果、補強板３０は、強化繊維（ガラス繊維及び炭素繊維等）又はタルクを含有する樹脂により形成されることが好ましい。 Regarding Examples 1 to 5, the strength of the port structural member when the reinforcing plate 30 is attached to the outer plate 20 is also examined. It was confirmed that the strength of the port structural member was basically secured by attaching the resin reinforcing plate 30 to the resin outer plate 20. However, as shown in Examples 1, 3 and 4, the strength was particularly good when the reinforcing plate 30 was formed of reinforcing fibers such as glass fibers or a resin such as polypropylene containing talc. As a result of the findings according to Examples 1 to 5 and various experiments, the reinforcing plate 30 is preferably formed of a reinforcing fiber (glass fiber, carbon fiber, etc.) or a resin containing talc.
　上記した第１実施形態によるポート構造によれば、以下の作用効果を得ることができる。 According to the port structure according to the first embodiment described above, the following effects can be obtained.
　本実施形態による充電用のポート構造は、樹脂製の外板２０と、ポート部材４０と、充電コネクタ３と、樹脂製の補強板３０とを備える。外板２０は、車体表面の一部を構成する外板部２１と、外板部２１から車体内側に延設される側壁２２と、側壁２２から当該側壁により囲われる内側空間側へと延設されるとともに、開口２３Ａを有する底板２３と、から構成されている。ポート部材４０は、底板２３の表面側に連結され、開口２３Ａを通じて車体内側に入り込んでいる。充電コネクタ３は、ポート部材４０に形成された開口４１Ａを通じて、車体外側に向かって臨むように配置されている。補強板３０は、外板部２１に沿って延設される外板補強部３１と、外板補強部３１から側壁２２に沿って延設される側壁補強部３２と、側壁補強部３２から底板２３に沿って延設されるとともにポート部材４０を通過させる開口３３Ａを有する底板補強部３３と、を備えている。外板補強部３１には、外板２０の裏面に当接することにより外板２０と補強板３０との間隔を規定する突起３４が形成されている。外板部２１と外板補強部３１、及び底板２３と底板補強部３３は、接着剤により接着されている。 The charging port structure according to the present embodiment includes a resin outer plate 20, a port member 40, a charging connector 3, and a resin reinforcing plate 30. The outer plate 20 extends from the outer plate portion 21 forming a part of the vehicle body surface, the side wall 22 extending from the outer plate portion 21 to the inside of the vehicle body, and from the side wall 22 to the inner space side surrounded by the side wall. It is also composed of a bottom plate 23 having an opening 23A. The port member 40 is connected to the surface side of the bottom plate 23 and enters the inside of the vehicle body through the opening 23A. The charging connector 3 is arranged so as to face the outside of the vehicle body through the opening 41A formed in the port member 40. The reinforcing plate 30 includes an outer plate reinforcing portion 31 extending along the outer plate portion 21, a side wall reinforcing portion 32 extending from the outer plate reinforcing portion 31 along the side wall 22, and a bottom plate from the side wall reinforcing portion 32. It is provided with a bottom plate reinforcing portion 33 extending along the 23 and having an opening 33A through which the port member 40 passes. The outer plate reinforcing portion 31 is formed with protrusions 34 that define the distance between the outer plate 20 and the reinforcing plate 30 by abutting against the back surface of the outer plate 20. The outer plate portion 21 and the outer plate reinforcing portion 31, and the bottom plate 23 and the bottom plate reinforcing portion 33 are adhered to each other by an adhesive.
　本実施形態では、補強板３０の突起３４により、外板２０と補強板３０との間を所定の間隔に規定することができ、外板部２１と外板補強部３１の間の接着層５１及び底板２３と底板補強部３３の間の接着層５２の厚さを所望の厚さとすることが可能となる。これにより、電力供給コネクタ接続時等に作用する外力に対して、外板２０及びポート部材４０の強度及び伸びを適切な範囲に設定することが可能となる。また、ポート部材４０は、底板２３の表面側に連結された状態で、開口２３Ａを通じて車体内側に入り込むような構成となっているため、ポート部材４０を外板２０に対して組み付けやすく、部材の組立性を高めることができる。 In the present embodiment, the protrusion 34 of the reinforcing plate 30 can define the space between the outer plate 20 and the reinforcing plate 30 at a predetermined interval, and the adhesive layer 51 between the outer plate portion 21 and the outer plate reinforcing portion 31 can be defined. The thickness of the adhesive layer 52 between the bottom plate 23 and the bottom plate reinforcing portion 33 can be set to a desired thickness. This makes it possible to set the strength and elongation of the outer plate 20 and the port member 40 within an appropriate range with respect to the external force acting when the power supply connector is connected or the like. Further, since the port member 40 is configured to enter the inside of the vehicle body through the opening 23A in a state of being connected to the surface side of the bottom plate 23, the port member 40 can be easily assembled to the outer plate 20 and the member can be easily assembled. Assemblability can be improved.
　また、本実施形態のポート構造によれば、外板２０には、ポートを開閉するための蓋部材４が配置されている。したがって、蓋部材４を閉じる際に生じる外力に対しても、外板２０及びポート部材４０の強度及び伸びを適切な範囲に設定することも可能となる。 Further, according to the port structure of the present embodiment, the outer plate 20 is provided with a lid member 4 for opening and closing the port. Therefore, it is possible to set the strength and elongation of the outer plate 20 and the port member 40 within an appropriate range with respect to the external force generated when the lid member 4 is closed.
　さらに、補強板３０の外板補強部３１に形成される突起３４は、外板補強部３１において側壁補強部３２寄りの位置に形成される。これにより、突起３４が補強板３０自体の部材中心により近い位置に配置されることとなるため、補強板３０と外板２０との間隔が所定の間隔に維持されやすくなる。 Further, the protrusion 34 formed on the outer plate reinforcing portion 31 of the reinforcing plate 30 is formed at a position closer to the side wall reinforcing portion 32 on the outer plate reinforcing portion 31. As a result, the protrusion 34 is arranged at a position closer to the center of the member of the reinforcing plate 30 itself, so that the distance between the reinforcing plate 30 and the outer plate 20 can be easily maintained at a predetermined distance.
　さらに、突起３４は、底板補強部３３の開口３３Ａの周囲に沿って複数設けられる。このように複数の突起３４を開口３３Ａの周囲に並設することで、補強板３０を外板２０の裏面にガタつきなく平行に取り付けることが可能となる。 Further, a plurality of protrusions 34 are provided along the periphery of the opening 33A of the bottom plate reinforcing portion 33. By arranging the plurality of protrusions 34 in parallel around the opening 33A in this way, the reinforcing plate 30 can be attached to the back surface of the outer plate 20 in parallel without rattling.
　さらに、突起３４は、縦方向断面が湾曲形状の突起として形成される。より具体的には、外板２０も車両上下方向になだらかに湾曲するように形成されており、突起３４の曲率は外板２０の曲率よりも大きく構成されている。このような曲面を持つ突起３４によれば、突起３４を外板部２１の裏面に滑らかに当接させることができ、当接部分における外板２０表面の外観に悪影響を与えることがない。さらに、突起３４が外板２０に対して線接触しやすく、補強板３０と外板２０との間隔が所定の間隔に維持されやすい。 Further, the protrusion 34 is formed as a protrusion having a curved vertical cross section. More specifically, the outer plate 20 is also formed so as to be gently curved in the vertical direction of the vehicle, and the curvature of the protrusion 34 is larger than the curvature of the outer plate 20. According to the protrusion 34 having such a curved surface, the protrusion 34 can be smoothly brought into contact with the back surface of the outer plate portion 21, and the appearance of the surface of the outer plate 20 at the contact portion is not adversely affected. Further, the protrusions 34 are likely to make line contact with the outer plate 20, and the distance between the reinforcing plate 30 and the outer plate 20 is likely to be maintained at a predetermined distance.
　さらに、外板２０の側壁２２と補強板３０の側壁補強部３２との間の空間は、外板部２１と外板補強部３１との間の空間、及び底板２３と底板補強部３３との間の空間とにそれぞれ連通している。そのため、外板２０と補強板３０との間に接着剤を多めに塗布したとしても、余剰の接着剤が側壁２２と側壁補強部３２との間の空間に流れ込むようになる。したがって、このような余剰の接着剤が車体表面側に溢れ出ることが防止される。また、外板２０と補強板３０とは、第１及び第２の接着層５１，５２だけでなく、外板部２１と外板補強部３１との間に漏れ出た接着剤によっても接着されるため、両部材の接着強度を高めることができる。 Further, the space between the side wall 22 of the outer plate 20 and the side wall reinforcing portion 32 of the reinforcing plate 30 is the space between the outer plate portion 21 and the outer plate reinforcing portion 31, and the space between the bottom plate 23 and the bottom plate reinforcing portion 33. It communicates with the space between them. Therefore, even if a large amount of adhesive is applied between the outer plate 20 and the reinforcing plate 30, excess adhesive will flow into the space between the side wall 22 and the side wall reinforcing portion 32. Therefore, it is possible to prevent such excess adhesive from overflowing to the surface side of the vehicle body. Further, the outer plate 20 and the reinforcing plate 30 are adhered not only by the first and second adhesive layers 51 and 52 but also by the adhesive leaked between the outer plate portion 21 and the outer plate reinforcing portion 31. Therefore, the adhesive strength of both members can be increased.
　さらに、外板２０は、補強板３０の突起３４と対向する部位が平坦面形状として形成されており、当該突起３４と係合又は嵌合するような部位を有しない構成となっている。樹脂製の外板２０において突起３４と当接する部分に係合部又は嵌合部を形成してしまうと、外板成形時に係合部又は嵌合部での成形収縮等によって外板表面にヒケが生じ、外観性状が悪化するおそれがある。本実施形態の外板２０では、突起３４との当接部分は平坦面となっているため、上述した外板２０の外観性状の悪化は生じない。 Further, the outer plate 20 is formed so that the portion of the reinforcing plate 30 facing the protrusion 34 has a flat surface shape and does not have a portion that engages or fits with the protrusion 34. If an engaging portion or a fitting portion is formed at a portion of the resin outer plate 20 that comes into contact with the protrusion 34, a sink mark is formed on the outer plate surface due to molding shrinkage at the engaging portion or the fitting portion during molding of the outer plate. May occur and the appearance may deteriorate. In the outer plate 20 of the present embodiment, since the contact portion with the protrusion 34 is a flat surface, the above-mentioned deterioration of the appearance property of the outer plate 20 does not occur.
　＜第２実施形態＞
　図６及び図７を参照して、第２実施形態による充電用ポート１０について説明する。図６は、第２実施形態による充電用ポート１０の縦方向一部断面図である。図７は、充電用ポート１０を構成する補強板３０の正面図である。 <Second Embodiment>
The charging port 10 according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is a partial vertical sectional view of the charging port 10 according to the second embodiment. FIG. 7 is a front view of the reinforcing plate 30 constituting the charging port 10.
　第１実施形態では補強板３０の外板補強部３１にのみ間隔調整部材としての突起３４が形成されているが、第２実施形態では補強板３０の外板補強部３１に突起３４が形成されるだけでなく、補強板３０の底板補強部３３にも突起３５が形成されている。 In the first embodiment, the protrusion 34 as an interval adjusting member is formed only on the outer plate reinforcing portion 31 of the reinforcing plate 30, but in the second embodiment, the protrusion 34 is formed on the outer plate reinforcing portion 31 of the reinforcing plate 30. Not only that, the protrusion 35 is also formed on the bottom plate reinforcing portion 33 of the reinforcing plate 30.
　図６に示すように、本実施形態では、一つの補強板３０に対して２種類の突起３４、３５が設けられており、これら突起３４，３５が外板２０の裏面に当接することで外板２０と補強板３０との間が所定の間隔に維持される。 As shown in FIG. 6, in the present embodiment, two types of protrusions 34, 35 are provided for one reinforcing plate 30, and these protrusions 34, 35 come into contact with the back surface of the outer plate 20 to be external. The space between the plate 20 and the reinforcing plate 30 is maintained at a predetermined interval.
　図７に示すように、底板補強部３３に形成される突起３５も、外板補強部３１の突起３４と同じ形状を有している。つまり、突起３５の突出高さは、突起３４の突出高さと同一となっている。突起３５は底板補強部３３の表面に複数形成されており、本実施形態では例えば４つ形成されている。これら４つの突起３５は、補強板３０の開口３３Ａの周囲に沿って並設されており、矩形状の開口３３Ａの長辺及び短辺の略中央に対応する位置にそれぞれ配置されている。より具体的には、外板補強部３１の突起３４と、底板補強部３３の突起３５とは、底板補強部３３の開口３３Ａの周方向に位置をずらしてそれぞれ配置される。 As shown in FIG. 7, the protrusion 35 formed on the bottom plate reinforcing portion 33 also has the same shape as the protrusion 34 of the outer plate reinforcing portion 31. That is, the protruding height of the protrusion 35 is the same as the protruding height of the protrusion 34. A plurality of protrusions 35 are formed on the surface of the bottom plate reinforcing portion 33, and in this embodiment, for example, four protrusions 35 are formed. These four protrusions 35 are arranged side by side along the periphery of the opening 33A of the reinforcing plate 30, and are arranged at positions corresponding to substantially the center of the long side and the short side of the rectangular opening 33A, respectively. More specifically, the protrusion 34 of the outer plate reinforcing portion 31 and the protrusion 35 of the bottom plate reinforcing portion 33 are arranged so as to be displaced from each other in the circumferential direction of the opening 33A of the bottom plate reinforcing portion 33.
　これら突起３４、３５の配置は、図７の配置に限らず、任意の位置に設定されてよい。また、突起３４、３５は、開口３３Ａを取り囲むような一本のライン状の突起として構成されてもよい。 The arrangement of these protrusions 34 and 35 is not limited to the arrangement shown in FIG. 7, and may be set at any position. Further, the protrusions 34 and 35 may be configured as a single line-shaped protrusion that surrounds the opening 33A.
　突起３５は、底板補強部３３上であれば、当該外板補強部３１の開口３３Ａ寄りの位置に形成されてもよいし、開口３３Ａよりも側壁補強部３２寄りの位置に形成されてもよい。図６に示すように、突起３５を開口３３Ａ寄りの位置に形成する場合には、突起３５が補強板３０自体の部材中心により近い位置に配置されることとなるため、補強板３０と外板２０との間隔が維持されやすい。 The protrusion 35 may be formed at a position closer to the opening 33A of the outer plate reinforcing portion 31 as long as it is on the bottom plate reinforcing portion 33, or may be formed at a position closer to the side wall reinforcing portion 32 than the opening 33A. .. As shown in FIG. 6, when the protrusion 35 is formed at a position closer to the opening 33A, the protrusion 35 is arranged at a position closer to the center of the member of the reinforcing plate 30 itself, so that the reinforcing plate 30 and the outer plate are arranged. The distance from 20 is easy to maintain.
　なお、本実施形態のポート構造においても、上述した表１の実施例１～５と同様の外板２０及び補強板３０の材質の組み合わせが採用され得る。 Also in the port structure of the present embodiment, the same material combination of the outer plate 20 and the reinforcing plate 30 as in Examples 1 to 5 of Table 1 described above can be adopted.
　上記した第２実施形態によるポート構造によれば、以下の作用効果を得ることができる。 According to the port structure according to the second embodiment described above, the following effects can be obtained.
　本実施形態によるポート構造では、補強板３０の外板補強部３１に突起３４が形成されるとともに、補強板３０の底板補強部３３に突起３５が形成されている。これら突起３４，３５により、補強板３０を外板２０の裏面にガタつきなく取り付けることができ、外板２０と補強板３０との間隔をより一定の間隔に維持することができる。その結果、外板部２１と外板補強部３１の間の接着層５１及び底板２３と底板補強部３３の間の接着層５２の厚さをより一定なものとすることができ、外板２０及びポート部材４０の強度及び伸びをより精度よく設定することが可能となる。 In the port structure according to the present embodiment, the protrusion 34 is formed on the outer plate reinforcing portion 31 of the reinforcing plate 30, and the protrusion 35 is formed on the bottom plate reinforcing portion 33 of the reinforcing plate 30. With these protrusions 34 and 35, the reinforcing plate 30 can be attached to the back surface of the outer plate 20 without rattling, and the distance between the outer plate 20 and the reinforcing plate 30 can be maintained at a more constant distance. As a result, the thickness of the adhesive layer 51 between the outer plate portion 21 and the outer plate reinforcing portion 31 and the thickness of the adhesive layer 52 between the bottom plate 23 and the bottom plate reinforcing portion 33 can be made more constant, and the outer plate 20 can be made more constant. And the strength and elongation of the port member 40 can be set more accurately.
　底板補強部３３の突起３５は、外板補強部３１の突起３４と同様、底板補強部３３の開口３３Ａの周囲に沿って複数設けられる。このように複数の突起３４、３５を開口３３Ａの周囲に並設することで、補強板３０を外板２０の裏面にガタつきなく平行に取り付けることが可能となる。 A plurality of protrusions 35 of the bottom plate reinforcing portion 33 are provided along the periphery of the opening 33A of the bottom plate reinforcing portion 33, similarly to the protrusions 34 of the outer plate reinforcing portion 31. By arranging the plurality of protrusions 34 and 35 side by side around the opening 33A in this way, the reinforcing plate 30 can be attached to the back surface of the outer plate 20 in parallel without rattling.
　さらに、外板補強部３１の突起３４と、底板補強部３３の突起３５とは、底板補強部３３の開口３３Ａの周方向に位置をずらして配置される。このような構成によれば、突起３４及び突起３５の突出高さが多少ばらついても、外板２０の裏面に取り付けた際にガタつきが生じにくく、外板２０と補強板３０との間隔を可能な限り所望の間隔に維持することができる。 Further, the protrusion 34 of the outer plate reinforcing portion 31 and the protrusion 35 of the bottom plate reinforcing portion 33 are arranged so as to be displaced in the circumferential direction of the opening 33A of the bottom plate reinforcing portion 33. According to such a configuration, even if the protrusion heights of the protrusions 34 and 35 vary slightly, rattling does not easily occur when the protrusions 34 and the protrusions 35 are attached to the back surface of the outer plate 20, and the distance between the outer plate 20 and the reinforcing plate 30 is increased. It can be maintained at the desired intervals as much as possible.
　以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 Although the embodiments of the present invention have been described above, the above embodiments are only a part of the application examples of the present invention, and the technical scope of the present invention is limited to the specific configurations of the above embodiments. Absent.
　例えば、図８に示すように、第１実施形態における補強板３０の裏面（内側面）には、外板補強部３１、側壁補強部３２、及び底板補強部３３のそれぞれの裏面に沿って延設されるリブ３６が形成されてもよい。リブ３６は、底板補強部３３の開口３３Ａの周囲に沿って複数形成されてもよい。このようなリブ３６は、充電用ポート１０の強度や伸びを高めるために必要に応じて採用される。リブ３６については、第１実施形態の充電用ポート１０だけでなく、第２実施形態の充電用ポート１０にも採用され得る。 For example, as shown in FIG. 8, the back surface (inner side surface) of the reinforcing plate 30 in the first embodiment extends along the back surfaces of the outer plate reinforcing portion 31, the side wall reinforcing portion 32, and the bottom plate reinforcing portion 33. The rib 36 to be provided may be formed. A plurality of ribs 36 may be formed along the periphery of the opening 33A of the bottom plate reinforcing portion 33. Such ribs 36 are adopted as necessary in order to increase the strength and elongation of the charging port 10. The rib 36 can be adopted not only in the charging port 10 of the first embodiment but also in the charging port 10 of the second embodiment.
　また、図８に示すように、補強板３０においては、当該補強板３０の軽量化を目的に、側壁補強部３２に一以上の貫通孔３２Ａを形成してもよい。貫通孔３２Ａについては、第１実施形態の充電用ポート１０だけでなく、第２実施形態の充電用ポート１０にも採用され得る。 Further, as shown in FIG. 8, in the reinforcing plate 30, one or more through holes 32A may be formed in the side wall reinforcing portion 32 for the purpose of reducing the weight of the reinforcing plate 30. The through hole 32A can be adopted not only in the charging port 10 of the first embodiment but also in the charging port 10 of the second embodiment.
　なお、上述した第１及び第２実施形態では、充電用ポート１０内に一つの充電コネクタ３が配置されているが、配置される充電コネクタの数は一つに限られない。例えば、充電用ポート１０内に、家庭用電源からの充電が可能な通常充電コネクタ、及び急速充電器からの充電が可能な急速充電コネクタの２つのコネクタを配置するようにしてもよい。 In the first and second embodiments described above, one charging connector 3 is arranged in the charging port 10, but the number of arranged charging connectors is not limited to one.

　また、第１及び第２実施形態では、ポートが電動車両１００の充電用ポートであるとして説明したが、当該ポートはガソリン又は軽油等を燃料とする車両の燃料供給用ポートであってもよい。ポートが燃料供給用ポートである場合は、燃料供給部がポート部材４０の開口４１Ａを通じてポート内に位置しており、燃料供給部の燃料供給口は車体外側に臨むように配置される。 Further, in the first and second embodiments, the port is described as a charging port for the electric vehicle 100, but the port may be a fuel supply port for a vehicle fueled by gasoline, light oil, or the like. When the port is a fuel supply port, the fuel supply unit is located inside the port through the opening 41A of the port member 40, and the fuel supply port of the fuel supply unit is arranged so as to face the outside of the vehicle body.
　さらに、充電用ポート１０又は燃料供給用ポートは、車両のフロントフェンダに形成されるのではなく、必要に応じて車両の任意の位置に形成され得る。 Further, the charging port 10 or the fuel supply port is not formed on the front fender of the vehicle, but may be formed at an arbitrary position on the vehicle as needed.
　第２実施形態では、補強板３０の外板補強部３１に突起３４を設け、補強板３０の底板補強部３３に突起３５を設けたが、突起３４は省略してもよい。つまり、外板２０と補強板３０との間隔を調整するための突起は、外板補強部３１及び底板補強部３３の少なくとも一方に形成されていればよい。 In the second embodiment, the protrusion 34 is provided on the outer plate reinforcing portion 31 of the reinforcing plate 30, and the protrusion 35 is provided on the bottom plate reinforcing portion 33 of the reinforcing plate 30, but the protrusion 34 may be omitted. That is, the protrusion for adjusting the distance between the outer plate 20 and the reinforcing plate 30 may be formed on at least one of the outer plate reinforcing portion 31 and the bottom plate reinforcing portion 33.
　上述した第１実施形態及び第２実施形態で説明した技術思想は適宜組み合わせが可能である。 The technical ideas described in the first embodiment and the second embodiment described above can be combined as appropriate.
