Abstract

PROBLEM TO BE SOLVED: To provide a charge port structure of a vehicle capable of enough protecting a pedestrian (a contact object).SOLUTION: In a charge port structure, a peripheral wall part 17 for blocking up a void between a charge port 10 and a connector bracket 15 in the periphery of charge connectors 12, 13 has a double-body structure including a charge port side peripheral wall part 18a and a connector bracket side peripheral wall part 18b having a lower elastic modulus than the charge port side peripheral wall part. The connector bracket side peripheral wall part is provided longer than the charge connectors extending over the whole periphery of the charge connectors, taking the face of the connector bracket as a starting point toward the disposition direction pointing the charge port side. In this configuration, when impact force more than predetermined travels, the connector bracket side peripheral wall part causes deformation to absorb the applied impact. Since the connector bracket side peripheral part is provided longer than the charge connector extending over the whole periphery of the charge connectors, taking the face of the connector bracket as a starting point toward the disposition direction pointing the charge port side, the length required for absorbing impact can be secured to exhibit satisfactory impact absorbing performance.

Description

本発明は、車体の前後方向端部に充電口を有する車両の充電口構造に関する。   The present invention relates to a charging port structure for a vehicle having a charging port at a longitudinal end portion of a vehicle body.

電気自動車やハイブリッド車など車両の充電口構造には、車体の前後方向端部の外板部材に充電口を設けて、外部の急速充電装置や家庭用電源装置などを使い、充電口内に配置されている充電コネクタから、充電を行えるようにしたものがある。
こうした充電口構造の多くは、充電口の内部（内側）に充電コネクタを配置し、同充電コネクタをプレート状のコネクタブラケットで車体に支持し、周壁部で、コネクタブラケットの充電コネクタ周りと充電口の開口周縁部との間の空隙を塞ぐ構造が用いられる（特許文献１を参照）。 The charging port structure of a vehicle such as an electric vehicle or a hybrid vehicle is provided with a charging port on the outer plate member at the end portion in the front-rear direction of the vehicle body, and is placed in the charging port using an external quick charging device or a household power supply device. There is something that can be charged from the charging connector.
In many of these charging port structures, a charging connector is arranged inside (inside) the charging port, the charging connector is supported on the vehicle body by a plate-shaped connector bracket, and around the charging connector of the connector bracket and the charging port on the peripheral wall portion. A structure is used that closes the gap between the peripheral edge of the opening (see Patent Document 1).

特開２００９−２９８２６３号公報JP 2009-298263 A

ところで、車体の前後方向前側に充電口の有る車両（電気自動車やハイブリッド車）は、充電口の開口を塞ぐ蓋体やコネクタブラケットや周壁部などにより、充電口が配置される外板部分が他の車体の外板部分よりも剛性が高くなる傾向にある。このため、車両の前端部と接触する接触対象物が歩行者となる場合、充電口の有る部分が歩行者に負担を与えるおそれがある。   By the way, in vehicles (electric vehicles or hybrid vehicles) having a charging port on the front side in the front-rear direction of the vehicle body, the outer plate part where the charging port is arranged is covered by a lid, a connector bracket, a peripheral wall, etc. There is a tendency for rigidity to be higher than the outer plate portion of the vehicle body. For this reason, when the contact target object which contacts the front-end part of a vehicle turns into a pedestrian, there exists a possibility that the part with a charging port may give a burden to a pedestrian.

特に電気自動車やハイブリッド車の多くは、特許文献１のように椀形のゴム製のシート部材が、単に充電コネクタの周り、具体的には充電コネクタの中段から上部までの間の大小の空隙を塞ぐように配置されるだけなので、衝撃力を十分に吸収できず、歩行者に対する保護が十分に行えない。
そこで、本発明の目的は、十分に歩行者（接触対象物）の保護が図れる車両の充電口構造を提供することにある。 In particular, in many of electric vehicles and hybrid vehicles, a saddle-shaped rubber sheet member as shown in Patent Document 1 simply has a large and small gap around the charging connector, specifically, from the middle stage to the upper part of the charging connector. Since it is arranged so as to block it, the impact force cannot be sufficiently absorbed and the pedestrian cannot be sufficiently protected.
Therefore, an object of the present invention is to provide a vehicle charging port structure that can sufficiently protect a pedestrian (contact object).

請求項１に記載の発明は、充電口の開口周縁部と充電コネクタの周りのコネクタブラケット間の空隙を塞ぐように設けられた周壁部は、充電口側に位置する充電口側周壁部と、コネクタブラケット側に位置するとともに充電口側周壁部よりも弾性率の低い第１の周壁部材で形成されたコネクタブラケット側周壁部とを備え、コネクタブラケット側周壁部は、コネクタブラケットの面を起点として充電口側に向かう配置方向に向かって、充電コネクタの全周に亘り、充電コネクタよりも長く設けられることとした。   According to the first aspect of the present invention, the peripheral wall provided so as to close the gap between the opening peripheral edge of the charging port and the connector bracket around the charging connector includes a charging port side peripheral wall portion positioned on the charging port side, And a connector bracket side peripheral wall portion formed of a first peripheral wall member that is located on the connector bracket side and has a lower elastic modulus than the charging port side peripheral wall portion, and the connector bracket side peripheral wall portion starts from the surface of the connector bracket In the arrangement direction toward the charging port side, the charging connector is provided longer than the charging connector over the entire circumference of the charging connector.

同構成によると、車体の前後方向の端部が歩行者（接触対象物）と接触し、車体の外板や周壁部から所定以上の衝撃力が伝わると、第１の周壁部材で形成されたコネクタブラケット側周壁部が変形を生じ、加わる衝撃を吸収する。特にコネクタブラケット側周壁部は、コネクタブラケットの面を起点として充電口側に向かう配置方向に向かって、充電コネクタの全周に亘り、充電コネクタよりも長く設けてあるから、衝撃吸収に必要な長さは確保され、十分なる衝撃吸収性能が発揮される。これで、歩行者保護（接触対象物の保護）が十分に行える。   According to this configuration, when the longitudinal end of the vehicle body comes into contact with a pedestrian (contact object) and an impact force of a predetermined level or more is transmitted from the outer plate or the peripheral wall portion of the vehicle body, the first peripheral wall member is formed. The connector bracket side peripheral wall is deformed and absorbs the applied impact. In particular, the peripheral wall of the connector bracket side is longer than the charging connector over the entire circumference of the charging connector toward the charging port side starting from the surface of the connector bracket. Therefore, sufficient shock absorbing performance is exhibited. Thus, pedestrian protection (contact object protection) can be sufficiently performed.

好ましくは、車体の前後部に組み付けられるバンパ部に充電口が設けられる場合、バンパ部の衝撃吸収特性が損なわれずにすむ。
請求項２に記載の発明は、さらに簡単な構造で、高い衝撃吸収性が確保されるよう、コネクタブラケットを、充電口と対向する向きで配置されたプレート状の部材から形成し、周壁部がプレート状のコネクタブラケットに対しほぼ垂直な向きとなる筒形でなし、第１の周壁部材で形成されたコネクタブラケット側周壁部にて、高い衝撃吸収性を発揮する座屈変形が生ずるようにした。 Preferably, when the charging port is provided in the bumper portion assembled to the front and rear portions of the vehicle body, the shock absorbing characteristics of the bumper portion are not impaired.
In the invention according to claim 2, the connector bracket is formed of a plate-like member arranged in a direction facing the charging port so that high shock absorption can be secured with a simple structure, and the peripheral wall portion is formed. A cylindrical shape that is oriented almost perpendicular to the plate-shaped connector bracket, and a buckling deformation that exhibits high shock absorption occurs in the peripheral wall portion of the connector bracket formed by the first peripheral wall member. .

請求項３に記載の発明は、充電口側周壁部を活用して衝撃吸収が行えるよう、充電口側周壁部は、所定の衝撃荷重で変形する第２の周壁部材から形成され、コネクタブラケット側周壁部を形成する第１の周壁部材は、第２の周壁部材よりも小さい衝撃荷重で変形することとし、始めにコネクタブラケット側周壁部が変形し、続いて充電口側周壁部が変形して、衝撃を吸収するようにした。   According to a third aspect of the present invention, the charging port side peripheral wall portion is formed of a second peripheral wall member that is deformed by a predetermined impact load so that the shock absorption can be performed by utilizing the charging port side peripheral wall portion. The first peripheral wall member forming the peripheral wall portion is deformed with a smaller impact load than the second peripheral wall member. First, the connector bracket side peripheral wall portion is deformed, and then the charging port side peripheral wall portion is deformed. To absorb the shock.

請求項４に記載の発明は、さらに衝撃荷重が効果的に吸収されるよう、充電口側周壁部とコネクタブラケット側周壁部との接合部をなす充電口側周壁部は、突起状に形成し、コネクタブラケット側周壁部は、突起状の充電口側周壁部を嵌受する形状に形成した。   According to a fourth aspect of the present invention, the charging port side peripheral wall portion forming the joint portion between the charging port side peripheral wall portion and the connector bracket side peripheral wall portion is formed in a protruding shape so that the impact load can be effectively absorbed. The connector bracket side peripheral wall portion is formed in a shape that fits the protruding charging port side peripheral wall portion.

請求項１の発明によれば、車体の前後方向の端部が接触対象物と接触した場合、外板部材などから、第１の周壁部材で形成されたコネクタブラケット側周壁部へ所定以上の衝撃力が加わると、コネクタブラケット側周壁部が変形（破壊）する。これにより、接触対象物が歩行者の場合、歩行者に作用する衝撃力は吸収される。しかも、コネクタブラケット側周壁部は、コネクタブラケットの面を起点として充電口側に向かう配置方向に向かって、充電コネクタの全周に亘り、充電コネクタよりも長く設けてあるから、衝撃吸収に必要な長さは確保され、十分なる衝撃吸収性能が発揮される。   According to the first aspect of the present invention, when the end of the vehicle body in the front-rear direction comes into contact with an object to be contacted, an impact of a predetermined level or more is applied from the outer plate member or the like to the connector bracket side peripheral wall formed by the first peripheral wall member When force is applied, the connector bracket side peripheral wall portion is deformed (destroyed). Thereby, when a contact target object is a pedestrian, the impact force which acts on a pedestrian is absorbed. In addition, the connector bracket side peripheral wall portion is provided longer than the charging connector over the entire circumference of the charging connector in the arrangement direction toward the charging port side starting from the surface of the connector bracket. The length is secured and sufficient shock absorbing performance is exhibited.

したがって、十分に歩行者の保護（接触対象物の保護）を図ることができる。
請求項２の発明によれば、プレート状のコネクタブラケットに対しほぼ垂直な向きで筒形の周壁部を配置するという簡単な構造によって、第１の周壁部材で形成されたコネクタブラケット側周壁部に座屈変形を引き起こさせるから、高い衝撃吸収性が確保できる。
請求項３の発明によれば、コネクタブラケット側周壁部だけでなく、充電口側周壁部を活用して、加わる衝撃力を吸収することができ、一層、効果的に歩行者（接触対象物）を保護することができる。 Therefore, it is possible to sufficiently protect the pedestrian (protect the contact object).
According to the invention of claim 2, the connector bracket side peripheral wall portion formed of the first peripheral wall member has a simple structure in which the cylindrical peripheral wall portion is arranged in a direction substantially perpendicular to the plate-shaped connector bracket. Since it causes buckling deformation, high shock absorption can be secured.
According to the invention of claim 3, not only the connector bracket side peripheral wall portion but also the charging port side peripheral wall portion can be utilized to absorb the applied impact force, and the pedestrian (contact object) can be more effectively obtained. Can be protected.

請求項４の発明によれば、衝撃荷重が加わることで、充電口側周壁部とコネクタブラケット側周壁部の接合部において、充電口側周壁部端にてコネクタブラケット側周壁部端を切り裂く挙動を生じさせ、このときの抵抗で衝撃荷重を吸収させることができ、一層、効果的に衝撃荷重を吸収することができる。   According to the invention of claim 4, when an impact load is applied, at the joint between the charging port side peripheral wall portion and the connector bracket side peripheral wall portion, the connector bracket side peripheral wall portion end is cut at the charging port side peripheral wall end. The impact load can be absorbed by the resistance at this time, and the impact load can be absorbed more effectively.

以下、本発明を図１ないし図５に示す第１の実施形態にもとづいて説明する。
図１は、本発明を適用した、例えば電気自動車やハイブリッド車など外部から充電を可能とした車両を前側から見た図を示している。
同車両について説明すると、図１中１は同車両の車体を示し、２は同車体１の前側に設けたフロントウインドを示し、３は、同フロントウインド２から車体前側に有るパワーユニットルーム（図示しない）の上部開口を覆うフードを示し、４は、同フード３の前側に設けたバンパ部を示している。 Hereinafter, the present invention will be described based on a first embodiment shown in FIGS.
FIG. 1 shows a front view of a vehicle to which the present invention is applied and which can be charged from the outside, such as an electric vehicle or a hybrid vehicle.
Referring to FIG. 1, reference numeral 1 denotes a vehicle body of the vehicle, 2 denotes a front window provided on the front side of the vehicle body 1, and 3 denotes a power unit room (not shown) located on the front side of the vehicle body from the front window 2. ) Shows the hood that covers the upper opening of 4), and 4 shows a bumper portion provided on the front side of the hood 3.

このうちバンパ部４は、例えば図２（図１中のＡ−Ａ線に沿う断面図）に示されるように、車体１の前部に配置されたバンパビーム７（車幅方向に延びるビーム部材）と、同バンパビーム７の前方近傍に配置されたバンパフェース８と有して構成される。バンパフェース８には、バンパビーム７の前側を覆う下部フェース８ａと、同下部フェース８ａとフード３の最前部との間の前部分を覆う上部フェース８ｂとを一体に形成したフェース部材が用いられる。つまり、車体１の前方側へ衝撃が加わると、バンパフェース８が変形して、衝撃力を緩和する。またバンパフェース８の変形がバンパビーム７に及ぶときは、バンパビーム７が変形して、衝撃力を吸収する。   Among these, the bumper portion 4 is, for example, as shown in FIG. 2 (a cross-sectional view taken along the line AA in FIG. 1), a bumper beam 7 (a beam member extending in the vehicle width direction) disposed at the front portion of the vehicle body 1. And a bumper face 8 disposed in the vicinity of the front of the bumper beam 7. For the bumper face 8, a face member is used in which a lower face 8 a that covers the front side of the bumper beam 7 and an upper face 8 b that covers a front portion between the lower face 8 a and the foremost part of the hood 3 are integrally formed. That is, when an impact is applied to the front side of the vehicle body 1, the bumper face 8 is deformed and the impact force is reduced. Further, when the deformation of the bumper face 8 reaches the bumper beam 7, the bumper beam 7 is deformed to absorb the impact force.

車体１のうち、前後方向端部である前側の端部を構成する外板部材、例えばバンパフェース８の上部フェース８ｂには、充電口構造が設けられている。この充電口構造には、図１に示されるように例えば上部フェース８ｂの車幅方向中央の地点に、プレート形の蓋体１０ａで塞げる充電口１０を設けた構造が用いられている。
充電口構造は、例えば急速充電装置の急速充電用ガン１１（充電ソケット：図１に図示）や家庭用電源装置に接続された普通充電用ガン（充電ソケット：図示しない）といった二種類のガンの接続を可能とした構造が用いられている。これには、図１および図２に示されるように例えば上部フェース８ｂの車幅方向中央に、車幅方向に延びる長方形状の充電口１０を形成し、この充電口１０から車体１の内側に、充電コネクタとして二種類のコネクタ、すなわち急速充電用コネクタ１２および普通充電用コネクタ１３や、両コネクタ１２，１３を車体１に支持するコネクタブラケット１５や、両コネクタ１２，１３の周囲の空隙を塞ぐ周壁部１７を組み付ける構造が用いられている。 In the vehicle body 1, a charging port structure is provided on an outer plate member that constitutes a front end that is an end in the front-rear direction, for example, an upper face 8 b of the bumper face 8. As shown in FIG. 1, for example, a structure in which a charging port 10 that is closed with a plate-shaped lid 10 a is provided at the center of the upper face 8 b in the vehicle width direction is used as the charging port structure.
The charging port structure includes, for example, two types of guns such as a quick charging gun 11 (charging socket: shown in FIG. 1) of a quick charging device and a normal charging gun (charging socket: not shown) connected to a household power supply device. A structure that enables connection is used. As shown in FIGS. 1 and 2, for example, a rectangular charging port 10 extending in the vehicle width direction is formed at the center of the upper face 8b in the vehicle width direction, and the charging port 10 is formed inside the vehicle body 1 from the charging port 10. Two types of charging connectors, that is, a quick charging connector 12 and a normal charging connector 13, a connector bracket 15 that supports both connectors 12, 13 on the vehicle body 1, and a gap around both connectors 12, 13 are closed. A structure in which the peripheral wall portion 17 is assembled is used.

具体的には図１および図２に示されるようにコネクタブラケット１５は、充電口１０と対向して配置された例えばプレート状の金属製部材から形成される。同ブラケット１５が、車体構成部材、例えばバンパビーム７や他の骨格部材（図示しない）などに強固に固定してある。急速充電用コネクタ１２や普通充電用コネクタ１３は、このコネクタブラケット１５の板面上に車幅方向に並べて組み付けてある。両コネクタ１２，１３は、いずれもコネクタブラケット１５を貫通し、充電ガンから電力を受ける筒形の入力部１２ａ，１３ａがコネクタブラケット１５の上面から突き出ている。ちなみに入力部１２ａ，１３ａの最上部には、それぞれ入力部１２ａ，１３ａの接続口（図示しない）を塞ぐ蓋部材１２ｂ、１３ｂが付いている。また電力を出力する出力部１２ｃ，１３ｃは、コネクタブラケット１５の下面から突き出ている。これら出力部１２ｂ，１３ｂが、各種ケーブル１９を介して、車体１に搭載されているバッテリユニットや普通充電器（いずれも図示しない）などと接続され、急速充電装置や家庭用電源装置を用いて充電が行えるようにしている。   Specifically, as shown in FIGS. 1 and 2, the connector bracket 15 is formed of, for example, a plate-shaped metal member disposed to face the charging port 10. The bracket 15 is firmly fixed to a vehicle body constituting member such as a bumper beam 7 or another skeleton member (not shown). The quick charging connector 12 and the normal charging connector 13 are assembled on the plate surface of the connector bracket 15 side by side in the vehicle width direction. Both connectors 12 and 13 penetrate the connector bracket 15, and cylindrical input portions 12 a and 13 a that receive power from the charging gun protrude from the upper surface of the connector bracket 15. Incidentally, lid members 12b and 13b for closing connection ports (not shown) of the input units 12a and 13a are attached to the uppermost portions of the input units 12a and 13a, respectively. The output portions 12 c and 13 c that output power protrude from the lower surface of the connector bracket 15. These output units 12b and 13b are connected to a battery unit mounted on the vehicle body 1 or a normal charger (both not shown) via various cables 19, and using a quick charger or a household power supply. Charging is possible.

図１および図２に示されるように周壁部１７は、充電口１０の開口周縁部１０ｂの縁形状にならう筒形（長方形状の枠形）をなしている。この筒形の周壁部１７の一端部が充電口１０の開口周縁部に固定、ここでは嵌合部２０によって固定されている。この固定により、周壁部１７の他端部が充電用コネクタ１２，１３の周りのコネクタブラケット１５の上面まで延びて配置され、周壁部１７全体で、充電口１０の開口周縁部１０ｂと充電用コネクタ１２，１３の周囲（周り）のコネクタブラケット１５の上面間の空隙を塞いでいる。   As shown in FIGS. 1 and 2, the peripheral wall portion 17 has a cylindrical shape (rectangular frame shape) that follows the edge shape of the opening peripheral edge portion 10 b of the charging port 10. One end of the cylindrical peripheral wall portion 17 is fixed to the peripheral edge of the opening of the charging port 10, here fixed by the fitting portion 20. By this fixing, the other end portion of the peripheral wall portion 17 is disposed so as to extend to the upper surface of the connector bracket 15 around the charging connectors 12 and 13, and the opening peripheral portion 10 b of the charging port 10 and the charging connector are formed in the entire peripheral wall portion 17. A gap between the upper surfaces of the connector brackets 15 around 12 and 13 is closed.

こうした充電口１０を有する車両は、充電口１０の配置される外板部分、ここではバンパ部４の車幅方向中央の部分が、同部分に組み付く蓋体１０ａやコネクタブラケット１５や周壁部１７などにより、他のバンパ部４の外板部分よりも剛性が高くなりやすく、車両の前端部が接触対象物、例えば歩行者と接触した場合、歩行者に負担を与えるおそれがある。   A vehicle having such a charging port 10 has a cover 10a, a connector bracket 15 and a peripheral wall portion 17 in which an outer plate portion where the charging port 10 is arranged, here a central portion in the vehicle width direction of the bumper portion 4 is assembled. For example, if the front end of the vehicle comes into contact with a contact object, such as a pedestrian, the pedestrian may be burdened.

そのため、充電口構造には、歩行者（接触対象物）を保護する工夫が施してある。
これには、図２に示されるように周壁部１７を、充電口１０側に位置する充電口側周壁部１８ａと、コネクタブラケット１５側に位置するコネクタブラケット側周壁部１８ｂとを備えた二体構造とし、コネクタブラケット側周壁部１８ｂを充電口側周壁部１８ａよりも弾性率の低い部材、例えばゴム部材（衝撃吸収部材）で形成された壁部２２（本願の第１の周壁部材に相当）で構成し、同壁部２２を、少なくともコネクタブラケット１５側の端部からコネクタ１２，１３（充電コネクタ）の最上部を超えた地点までの領域に形成する構造が用いられている。具体的にはゴム製の壁部２２（コネクタブラケット側周壁部１８ｂ）は、コネクタブラケット１５側の端部からコネクタ１２，１３の最上部を若干、超えた地点ｔまでに形成されている。これで、ゴム製の壁部２２（コネクタブラケット側周壁部１８ｂ）は、コネクタブラケット１５の面（上面）を起点として充電口１０側に向かう配置方向（図２中Ｘ）に向かって、コネクタ１２，１３の全周に亘り、コネクタ１２，１３よりも長く設けてある。図２中Ｔは、そのコネクタ１２，１３の最上部を超えた地点ｔまでの領域を示している。これにより、壁部２２は、全周において衝撃を吸収するのに十分な全長（長さ）を確保している。つまり、歩行者との接触により、壁部２２の衝突荷重を超える衝撃力（所定以上の衝撃力）が加わるような場合、壁部２２が、十分な衝撃吸収ストロークのもとで変形（破壊）し、加わる衝撃力を吸収する。 Therefore, the charging port structure is devised to protect pedestrians (contact objects).
For this purpose, as shown in FIG. 2, the peripheral wall portion 17 has two bodies including a charging port side peripheral wall portion 18a positioned on the charging port 10 side and a connector bracket side peripheral wall portion 18b positioned on the connector bracket 15 side. The connector bracket side peripheral wall portion 18b has a structure and a wall portion 22 formed of a member having a lower elastic modulus than the charging port side peripheral wall portion 18a, for example, a rubber member (shock absorbing member) (corresponding to the first peripheral wall member of the present application) The wall portion 22 is formed in a region at least from the end on the connector bracket 15 side to a point beyond the uppermost portion of the connectors 12 and 13 (charging connector). Specifically, the rubber wall portion 22 (connector bracket side peripheral wall portion 18b) is formed from the end portion on the connector bracket 15 side to a point t slightly beyond the uppermost portions of the connectors 12 and 13. The rubber wall portion 22 (connector bracket side peripheral wall portion 18b) is thus connected to the connector 12 in the direction (X in FIG. 2) toward the charging port 10 side with the surface (upper surface) of the connector bracket 15 as a starting point. , 13 is provided longer than the connectors 12, 13 over the entire circumference. T in FIG. 2 indicates a region up to the point t beyond the top of the connectors 12 and 13. Thereby, the wall part 22 has ensured sufficient full length (length) to absorb an impact in the perimeter. That is, when an impact force exceeding the collision load of the wall portion 22 (impact force greater than a predetermined value) is applied due to contact with the pedestrian, the wall portion 22 is deformed (destructed) under a sufficient shock absorption stroke. And absorb the applied impact force.

特にゴム製の壁部２２で、高い衝撃吸収性が得られるよう、プレート状のコネクタブラケット１５は、コネクタ１２，１３の軸線と直交する向きに配置され、周壁部１７は、プレート状のコネクタブラケット１５に対しほぼ垂直となる向きで配置してある。つまり、ゴム製の壁部２２で、高い衝撃吸収性を発揮する座屈変形が生ずる構造としている。
またゴム製の壁部２２以外の周壁部分を活用して衝撃吸収が行えるよう、垂直な向きに配置された周壁部１７のうち、充電口側周壁部１８ａをなすＴ範囲外の充電口１０の開口周縁部１０ｂ側の端部からコネクタ１２，１３の最上部に近い地点までは、所定の衝撃荷重δ１で変形する周壁部材、例えば合成樹脂部材（本願の第２の周壁部材に相当）の周壁で形成され、コネクタブラケット側周壁部１８ｂをなすＴ範囲のコネクタ１２，１３の最上部を超えた地点からコネクタブラケット１５側の端部までは、上記充電口側周壁部１８ｂをなす合成樹脂部材よりも小さい衝撃荷重δ２で変形するゴム部材で形成され、同二体構造（δ１＞δ２）により、加わる衝撃力の大きさに応じた衝撃吸収が行える構造としている。むろん両部材は、接合（連結）してある。 In particular, the plate-like connector bracket 15 is arranged in a direction perpendicular to the axes of the connectors 12 and 13 so that high shock absorption can be obtained with the rubber wall portion 22, and the peripheral wall portion 17 is formed with the plate-like connector bracket. 15 is arranged in a direction that is substantially perpendicular to 15. That is, the rubber wall portion 22 has a structure in which buckling deformation that exhibits high shock absorption occurs.
Further, among the peripheral wall portions 17 arranged in a vertical direction so as to be able to absorb the impact by utilizing the peripheral wall portion other than the rubber wall portion 22, the charging port 10 outside the T range that forms the charging port side peripheral wall portion 18a. From the end on the opening peripheral edge 10b side to a point close to the top of the connectors 12 and 13, a peripheral wall member that deforms with a predetermined impact load δ1, for example, a peripheral wall of a synthetic resin member (corresponding to the second peripheral wall member of the present application) From the point exceeding the uppermost part of the connectors 12 and 13 in the T range forming the connector bracket side peripheral wall portion 18b to the end portion on the connector bracket 15 side, the synthetic resin member forming the charging port side peripheral wall portion 18b is used. Also, it is formed of a rubber member that is deformed by a small impact load δ2, and has a structure that can absorb impact according to the magnitude of the applied impact force by the two-body structure (δ1> δ2). Of course, both members are joined (connected).

つぎに、このように構成された充電口構造の作用について説明する。
ここでは、図３に示されるように例えば車両が停止する寸前で、車両前部である充電口１０ｂの蓋体１０ａ並びにその周辺のバンパフェース部分（上部フェース８ｂ）と、歩行者ａ（接触対象物）とが接触した場合を想定する。
このとき、接触に伴う衝撃力は、蓋体１０ａや上部フェース８ｂ（バンパ部４）などから、周壁部１７を経て、コネクタブラケット１５へ伝わる。このとき、加わる衝撃力Ｆが、ゴム製の壁部２２に定めてある衝突荷重、すなわち歩行者ａとの接触を対象として設定した設定衝突荷重値を超えたとする。すると、図４のＹ部に示されるようにゴム製の壁部２２は座屈変形を起こし、同座屈変形と共に変形する上部フェース８ｂや蓋体１０ａの変形と共に、衝撃力Ｆを吸収し、歩行者ａを衝撃力Ｆから保護する。 Next, the operation of the charging port structure configured as described above will be described.
Here, as shown in FIG. 3, for example, just before the vehicle stops, the lid 10a of the charging port 10b, which is the front of the vehicle, the bumper face portion (upper face 8b) around it, and the pedestrian a (contact object) Suppose the case is in contact with the object.
At this time, the impact force accompanying the contact is transmitted to the connector bracket 15 via the peripheral wall portion 17 from the lid body 10a, the upper face 8b (bumper portion 4) and the like. At this time, it is assumed that the applied impact force F exceeds the collision load set on the rubber wall 22, that is, the set collision load value set for contact with the pedestrian a. Then, as shown in the Y part of FIG. 4, the rubber wall portion 22 undergoes buckling deformation, and the impact force F is absorbed along with the deformation of the upper face 8b and the lid body 10a which are deformed together with the buckling deformation, The pedestrian a is protected from the impact force F.

この際、ゴム製の壁部２２は、コネクタブラケット１５の面（上面）を起点として、充電口１０側に向かう配置方向に向かって、各コネクタ１２，１３の全周に亘り延びている。具体的には壁部２２は、コネクタ１２，１３の最上部を若干、超えた地点まで形成され、コネクタ１２，１３の全周に亘り、衝撃を吸収するのに十分な全長（長さ）を確保してある。そのため、壁部２２は、十分な衝撃吸収ストロークのもとで変形（破壊）を起こし、十分に衝撃力Ｆを吸収する。   At this time, the rubber wall 22 extends from the surface (upper surface) of the connector bracket 15 over the entire circumference of the connectors 12 and 13 in the arrangement direction toward the charging port 10 side. Specifically, the wall portion 22 is formed to a point slightly beyond the uppermost portions of the connectors 12 and 13, and has a full length (length) sufficient to absorb an impact over the entire circumference of the connectors 12 and 13. Secured. Therefore, the wall portion 22 is deformed (destructed) under a sufficient shock absorbing stroke and sufficiently absorbs the impact force F.

加わる衝撃力が大きいと、図５のＺ部に示されるように、ゴム製の壁部２２の変形に続いて、残る合成樹脂製の周壁部、すなわち充電口側周壁部１８ａが変形（破壊）を起こす。これにより、さらに衝撃吸収が行われ、歩行者ａを衝撃力Ｆから保護する。
したがって、車両前後方向端部（ここでは前端部）に充電口１０が配置される車両でも、十分に歩行者の保護（接触対象物の保護）を図ることができる。特に充電口１０がバンパ部４に設けられる場合、充電口構造が十分に衝撃吸収を果たすため、バンパ部４の衝撃吸収特性が損なわれずにすむ。 When the applied impact force is large, the remaining synthetic resin peripheral wall portion, that is, the charging port side peripheral wall portion 18a is deformed (destructed) following the deformation of the rubber wall portion 22, as shown in the Z portion of FIG. Wake up. This further absorbs the impact and protects the pedestrian a from the impact force F.
Therefore, even in a vehicle in which the charging port 10 is arranged at the end portion in the front-rear direction of the vehicle (here, the front end portion), it is possible to sufficiently protect the pedestrian (protect the contact object). In particular, when the charging port 10 is provided in the bumper part 4, the charging port structure sufficiently absorbs the shock, so that the shock absorption characteristic of the bumper part 4 is not impaired.

しかも、筒形の周壁部１７をコネクタブラケット１５に対しほぼ垂直に配置したことで、ゴム製の壁部２２は、高い衝撃吸収もたらす座屈変形を生じさせることができ、簡単な構造で、高い衝撃吸収性を確保することができる。
そのうえ、周壁部１７を合成樹脂製の周壁部分とゴム製の周壁部分との二体構造したことで、ゴム製の壁部２２だけでなく、他の周壁部分を活用して、加わる衝撃力Ｆを吸収することができ、一層、効果的に歩行者（接触対象物）の保護ができる。 In addition, since the cylindrical peripheral wall portion 17 is arranged substantially perpendicular to the connector bracket 15, the rubber wall portion 22 can cause buckling deformation resulting in high shock absorption, and has a simple structure and high height. Shock absorption can be secured.
In addition, since the peripheral wall portion 17 is composed of a synthetic resin peripheral wall portion and a rubber peripheral wall portion, an impact force F applied by utilizing not only the rubber wall portion 22 but also other peripheral wall portions. Can be absorbed, and pedestrians (contact objects) can be more effectively protected.

図５は、本発明の第２の実施形態を示す。
本実施形態は、衝撃力をゴム製の壁部２２の座屈変形で吸収する以外に、他の変形によっても吸収されるようにしたものである。
具体的には、例えば図６（ａ）に示されるように合成樹脂製の筒形の充電口側周壁部１８ａの端部とゴム製の筒形のコネクタブラケット側周壁部１８ｂの端部とが接合される接合部分のうち、充電口側周壁部１８ａの端を突起状、例えば鋭角的な三角形状の断面部分をもつテーパ部２５に形成し、コネクタブラケット側周壁部１８の端を、同テーパ部２５を嵌受する形状、例えばＶ形状部２６に形成して、衝突荷重が加わると、図６（ｂ）に示されるようにテーパ部２５の先端がＶ形状部２６の底側へ進入して、テーパ部２５で、壁部２２をＶ形状部２６を底側から切り裂き、その壁部２２を裂くときの抵抗で、衝撃力Ｆを吸収するようにしたものである。このように、合成樹脂製の筒形の充電口側周壁部１８ａとゴム製の筒形のコネクタブラケット側周壁部１８ｂとの接合部は、合成樹脂製の充電口側周壁部１８ａを突起状に形成し、ゴム製のコネクタブラケット側周壁部１８ｂを突起状の合成樹脂製の充電口側周壁部１８ａを嵌受する形状に形成することで、突起状の合成樹脂製の充電口側周壁部１８ａからゴム製のコネクタブラケット側周壁部１８ｂに伝達される衝撃荷重を効果的に吸収することが可能となる。接合部における充電口側周壁部１８ａの突起状の形状は、上記のような鋭角的な断面三角形状に限られず、断面凸形状でもよく、もちろん、他の構造でも構わない。 FIG. 5 shows a second embodiment of the present invention.
In the present embodiment, the impact force is absorbed not only by buckling deformation of the rubber wall portion 22 but also by other deformations.
Specifically, for example, as shown in FIG. 6A, the end of the cylindrical charging port side peripheral wall 18a made of synthetic resin and the end of the rubber cylindrical connector bracket side peripheral wall 18b are formed. Of the joined portions to be joined, the end of the charging port side peripheral wall portion 18a is formed into a taper portion 25 having a projecting shape, for example, an acute triangular cross section, and the end of the connector bracket side peripheral wall portion 18 is tapered. When a collision load is applied to a shape that fits the portion 25, for example, a V-shaped portion 26, the tip of the tapered portion 25 enters the bottom side of the V-shaped portion 26 as shown in FIG. The taper portion 25 cuts the wall portion 22 from the bottom side of the V-shaped portion 26 and absorbs the impact force F by resistance when the wall portion 22 is torn. Thus, the joint portion between the cylindrical charging port side peripheral wall portion 18a made of synthetic resin and the rubber cylindrical connector bracket side peripheral wall portion 18b has a protruding shape on the charging port side peripheral wall portion 18a made of synthetic resin. By forming the rubber connector bracket side peripheral wall portion 18b into a shape that fits the protruding synthetic resin charging port side peripheral wall portion 18a, the protruding synthetic resin charging port side peripheral wall portion 18a is formed. It is possible to effectively absorb the impact load transmitted from the rubber connector bracket side peripheral wall portion 18b to the rubber connector bracket side peripheral wall portion 18b. The shape of the protrusion of the charging port side peripheral wall portion 18a at the joint is not limited to the acute triangular cross section as described above, and may be a convex cross section, or of course other structures.

このようにしても一実施形態と同様の効果を奏する。但し、図６（ａ），（ｂ）において一実施形態と同じ部分には、同一符号を付して、その説明を省略した。
なお、本発明は、上述した実施形態に限定されるものではなく、本発明の主旨を逸脱しない範囲内で種々可変して実施しても構わない。例えば上述した実施形態のゴム製のコネクタブラケット側周壁部は、充電コネクタの最上部を若干、超えた地点まで形成したが、それ以上、充電口寄りの地点まで形成してもよく、少なくともコネクタブラケットの面を起点として充電コネクタの最上部を超えた地点まで延ばして形成されていればよい。また上述の実施形態では、充電口をバンパ部に設けた例を挙げたが、バンパ部以外の車両の端部外板、例えばフロントグリルの一部など設けた構造でも構わない。 Even if it does in this way, there exists an effect similar to one Embodiment. However, in FIGS. 6A and 6B, the same parts as those in the embodiment are denoted by the same reference numerals, and the description thereof is omitted.
Note that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. For example, the rubber connector bracket side peripheral wall portion of the embodiment described above is formed to a point slightly beyond the uppermost portion of the charging connector, but may be formed to a point closer to the charging port, at least the connector bracket. As long as the surface of the charging connector is used as a starting point, it may be formed so as to extend to a point beyond the top of the charging connector. Moreover, although the example which provided the charging port in the bumper part was given in the above-mentioned embodiment, the structure which provided the edge part outer plate of vehicles other than a bumper part, for example, a part of front grill, etc. may be sufficient.
