Description

本発明は、車両における供給ラインの共通接続構造に関する。 The present invention relates to a common connection structure of supply lines in a vehicle.

従来、環境に配慮した車両として、天然ガスや水素ガスなどを燃料として内燃機関を駆動させ走行する天然ガス自動車や水素自動車などの開発が行われてきた。さらに近年では、内燃機関に代わり、電動モータを駆動力源として走行する電動車両が注目を集めている。 Conventionally, as environment-friendly vehicles, natural gas vehicles and hydrogen vehicles that run by driving an internal combustion engine using natural gas or hydrogen gas as fuel have been developed. Furthermore, in recent years, electric vehicles that travel using an electric motor as a driving force source instead of an internal combustion engine have been attracting attention.

電動車両としては、例えば電動モータを駆動するための電気エネルギーを発生させる燃料電池を搭載した燃料電池自動車(FCV:Fuel Cell Vehicle)や、蓄電池に蓄積した電気エネルギーだけを使用して走行する電気自動車(EV:Electric Vehicle)などがある。 Examples of electric vehicles include fuel cell vehicles (FCVs) equipped with fuel cells that generate electric energy to drive electric motors, and electric vehicles that travel using only the electric energy stored in storage batteries. (EV: Electric Vehicle) and so on.

このうち、天然ガス自動車や水素自動車、燃料電池自動車など、燃料ガスを使用する車両においては、燃料ガスを貯蔵する燃料ガスタンクが搭載され、ここからガス配管(ガス供給ライン)を介して内燃機関や燃料電池に対し燃料ガスが供給される構成となっている(例えば、特許文献1参照)。 Of these, vehicles that use fuel gas, such as natural gas vehicles, hydrogen vehicles, and fuel cell vehicles, are equipped with a fuel gas tank that stores fuel gas, and from here, an internal combustion engine or an internal combustion engine via a gas pipe (gas supply line). The fuel gas is supplied to the fuel cell (see, for example, Patent Document 1).

これに対し、電気自動車においては、搭載した蓄電池から電気配線(電力供給ライン)を介して電動モータに対し電力供給が行われる構成となっている。 On the other hand, in an electric vehicle, electric power is supplied from a mounted storage battery to an electric motor via an electric wiring (electric power supply line).

There are concerns about an increase.

これに鑑み、仮にエネルギー供給源となる燃料ガスタンクと蓄電池とを載せ替え可能な共通の車両プラットフォームを採用した場合には、この車両プラットフォームに対し、使用の有無に拘らず、予めガス供給系(ガス配管及びこれと燃料ガスタンクを接続する部材など)と、電力供給系(電気配線及びこれと蓄電池を接続する部材など)の2系統を設置しておく必要が生じる。 In view of this, if a common vehicle platform in which the fuel gas tank and the storage battery, which are the energy supply sources, can be replaced is adopted, the gas supply system (gas) is used for this vehicle platform in advance regardless of whether or not it is used. It is necessary to install two systems, such as a pipe and a member connecting this to the fuel gas tank) and a power supply system (such as an electric wiring and a member connecting this to the storage battery).

A fuel cell vehicle 1A is shown, and (b) shows an electric vehicle 1B equipped with a storage battery as an energy supply source.

但し、図1(a),(b)においては、本発明に係る主要な構成要素だけを図示している。勿論、この他にも、車両1A,1Bには、車両としての種々の構成要素が搭載されているが、簡素化のため、それらの図示及び説明は省略する。また、車両1A,1Bに重複する部分については、同一の部材名称、同一の符号を用いる等して重複説明を省略する。 However, in FIGS. 1A and 1B, only the main components according to the present invention are shown. Of course, in addition to this, various components as a vehicle are mounted on the vehicles 1A and 1B, but their illustration and description are omitted for the sake of simplification. Further, for the parts overlapping the vehicles 1A and 1B, the same member names and the same reference numerals are used, and the overlapping description will be omitted.

尚、本実施形態における車両1A,1Bの基本骨格を構成する車両プラットフォームには、燃料ガスタンクの形状に合わせて、円筒型貯蔵体を搭載可能な貯蔵体設置部10が設けられている。つまり、この車両プラットフォームの仕様においては、燃料ガスが貯蔵される燃料ガスタンクや、電気エネルギーを蓄える蓄電池など、貯蔵するエネルギー形態が異なるエネルギー貯蔵体の形状を円筒形状に統一することにより、同一の貯蔵体設置部10に対し、いずれかを選択して設置することができるよう構成されている。 The vehicle platform constituting the basic skeletons of the vehicles 1A and 1B in the present embodiment is provided with a storage body installation portion 10 on which a cylindrical storage body can be mounted according to the shape of the fuel gas tank. In other words, in the specifications of this vehicle platform, the same storage is performed by unifying the shape of energy storage bodies that store different energy forms, such as fuel gas tanks that store fuel gas and storage batteries that store electrical energy, into a cylindrical shape. It is configured so that any one can be selected and installed on the body installation unit 10.

まず図1(a)に示す燃料電池自動車1Aについて詳しく説明する。燃料電池自動車1Aは、主要な構成要素として、車両本体としての車体(ボディ)2と、駆動輪としての左右一対の前輪3と、従動輪としての左右一対の後輪4と、前輪3を駆動させる駆動力源としての電動モータ5と、該電動モータ5への電力供給を制御するパワーコントロールユニット6(以下、「PCU6」という)と、電動モータ5(PCU6)へ供給する電気を発生させる燃料電池システム7と、燃料ガスとしての水素ガスを貯蔵する燃料ガスタンクとしての高圧水素タンク8と、高圧水素タンク8から燃料電池システム7へ水素ガスを供給するガス供給ラインとしての水素供給用配管LAとを備えている。 First, the fuel cell vehicle 1A shown in FIG. 1A will be described in detail. The fuel cell vehicle 1A drives a vehicle body (body) 2 as a vehicle body, a pair of left and right front wheels 3 as drive wheels, a pair of left and right rear wheels 4 as driven wheels, and a front wheel 3 as main components. An electric motor 5 as a driving force source to be driven, a power control unit 6 (hereinafter referred to as "PCU6") for controlling power supply to the electric motor 5, and a fuel for generating electricity to be supplied to the electric motor 5 (PCU6). A battery system 7, a high-pressure hydrogen tank 8 as a fuel gas tank for storing hydrogen gas as a fuel gas, and a hydrogen supply pipe LA as a gas supply line for supplying hydrogen gas from the high-pressure hydrogen tank 8 to the fuel cell system 7. It is equipped with.

燃料電池システム7は、反応ガスである酸化ガスおよび水素ガスの供給を受けて電気化学反応により発電する燃料電池スタック7Aを備えている。 The fuel cell system 7 includes a fuel cell stack 7A that receives power from oxidation gas and hydrogen gas, which are reaction gases, to generate electricity by an electrochemical reaction.

この他、図示は省略するが、燃料電池システム7には、酸化ガスを燃料電池スタック7Aに供給する酸化ガス供給系や、水素ガスを燃料電池スタック7Aに供給する水素ガス供給系、冷却媒体を循環させる冷却系、各種オフガスや生成水などを車外へ排出するための排出系などが設けられている。 In addition, although not shown, the fuel cell system 7 includes an oxidation gas supply system that supplies oxidation gas to the fuel cell stack 7A, a hydrogen gas supply system that supplies hydrogen gas to the fuel cell stack 7A, and a cooling medium. It is equipped with a cooling system that circulates, and a discharge system for discharging various off-gas and generated water to the outside of the vehicle.

燃料電池スタック7Aは、多数の発電セル(単セル)が積層されたスタック構造を有する固体高分子型燃料電池である。発電セルは、電解質膜の両側に、それぞれ触媒層とガス拡散層とからなるアノード(燃料極)及びカソード(空気極)を配設した膜電極複合体(MEA)が一対のセパレータにより挟持されてなる。 The fuel cell stack 7A is a polymer electrolyte fuel cell having a stack structure in which a large number of power generation cells (single cells) are stacked. In the power generation cell, a membrane electrode composite (MEA) in which an anode (fuel electrode) and a cathode (air electrode) composed of a catalyst layer and a gas diffusion layer are arranged on both sides of an electrolyte membrane is sandwiched by a pair of separators. Become.

燃料電池スタック7Aには、水素ガスや酸化ガス、冷却媒体を流通させるための各種流路が発電セルの積層方向に沿って形成されている。かかる構成の下、各発電セルのアノードには水素ガスが供給され、カソードには酸化ガスとしての空気が供給される。アノードに水素ガスが供給されることで、これに含まれる水素がアノードを構成する触媒層の触媒と反応し、これによって水素イオンが発生する。発生した水素イオンは電解質膜を通過して、カソードで空気に含まれる酸素と化学反応を起こす。この化学反応によって電気が発生する。燃料電池スタック7Aで発生した電気は、図示しない昇圧コンバータ等を介してPCU6へ入力される。 In the fuel cell stack 7A, various flow paths for circulating hydrogen gas, oxidation gas, and a cooling medium are formed along the stacking direction of the power generation cells. Under such a configuration, hydrogen gas is supplied to the anode of each power generation cell, and air as an oxidizing gas is supplied to the cathode. When hydrogen gas is supplied to the anode, the hydrogen contained therein reacts with the catalyst of the catalyst layer constituting the anode, thereby generating hydrogen ions. The generated hydrogen ions pass through the electrolyte membrane and cause a chemical reaction with oxygen contained in the air at the cathode. This chemical reaction produces electricity. The electricity generated by the fuel cell stack 7A is input to the PCU 6 via a boost converter or the like (not shown).

次に、貯蔵体設置部10に設置される高圧水素タンク8、並びに、これと水素供給用配管LAとを接続する接続構造について説明する。以下、これら各種構成について説明する際には、貯蔵体設置部10に設置される円筒型貯蔵体(高圧水素タンク8や後述するバッテリーパック50)の中心軸を通る軸線C1を、接続構造における共通の基準線として用いることとする。 Next, the high-pressure hydrogen tank 8 installed in the storage body installation unit 10 and the connection structure for connecting the high-pressure hydrogen tank 8 and the hydrogen supply pipe LA will be described. Hereinafter, when these various configurations are described, the axis C1 passing through the central axis of the cylindrical storage body (high pressure hydrogen tank 8 and the battery pack 50 described later) installed in the storage body installation unit 10 is common in the connection structure. It will be used as the reference line of.

高圧水素タンク8は、水素ガスを高圧で貯蔵するためのものである。図2(a),(b)に示すように、高圧水素タンク8の本体部20(以下、「タンク本体部20」という)は、円筒形状をなす直胴部21と、その両端に形成された略半球状のドーム部22とからなる。 The high-pressure hydrogen tank 8 is for storing hydrogen gas at a high pressure. As shown in FIGS. 2 (a) and 2 (b), the main body 20 (hereinafter referred to as “tank main body 20”) of the high-pressure hydrogen tank 8 is formed in a cylindrical straight body 21 and both ends thereof. It is composed of a substantially hemispherical dome portion 22.

尚、詳細な図示は省略するが、タンク本体部20は、例えばガスバリア機能を有するプラスチックライナー、その外側に耐圧強度を高めるための炭素繊維強化プラスチック(CFRP)層、さらにその外側に表面を保護するガラス繊維強化プラスチック(GFRP)層を有する3層構造となっている。 Although detailed illustration is omitted, the tank body 20 has, for example, a plastic liner having a gas barrier function, a carbon fiber reinforced plastic (CFRP) layer on the outside thereof for increasing pressure resistance, and a surface on the outside thereof. It has a three-layer structure with a glass fiber reinforced plastic (GFRP) layer.

高圧水素タンク8には、タンク本体部20の軸線C1方向一端部において金属製の口金23が設けられている。図3(a),(b)に示すように、口金23にはバルブアッセンブリ25(以下、単に「バルブ25」という)が取付けられている。 The high-pressure hydrogen tank 8 is provided with a metal base 23 at one end of the tank body 20 in the axis C1 direction. As shown in FIGS. 3A and 3B, a valve assembly 25 (hereinafter, simply referred to as “valve 25”) is attached to the base 23.

尚、バルブ25は、高圧水素タンク8の内部と外部との間で水素ガスの給排を制御するためのものであり、本来であれば、水素ガスの流れを制御する各種弁機構(電磁弁や圧抜弁、逆止弁など)や、水素ガス充填用の流路など種々の構成要素を備えているが、本願の各図面においては、簡素化のため、本発明に係る主要な構成要素のみを図示し、その他の構成要素については図示及び説明を省略する。 The valve 25 is for controlling the supply and discharge of hydrogen gas between the inside and the outside of the high-pressure hydrogen tank 8, and is originally a various valve mechanism (solenoid valve) for controlling the flow of hydrogen gas. , Press valve, check valve, etc.) and a flow path for filling hydrogen gas, etc., but in each drawing of the present application, for the sake of simplicity, only the main components according to the present invention are provided. Is illustrated, and illustration and description of other components are omitted.

図7(a),(b)に示すように、バルブ25は、タンク本体部20内に配置されるノズル部26と、口金23に取付けられる取付部27と、タンク本体部20外に配置される頭部28とが金属材料等により一体形成された本体部を有し、該本体部には軸線C1方向に貫通するガス流通経路29が形成されている。「ガス流通経路29」が本実施形態における「第2ガス流通経路」を構成する。 As shown in FIGS. 7 (a) and 7 (b), the valve 25 is arranged outside the nozzle portion 26 arranged in the tank main body portion 20, the mounting portion 27 attached to the base 23, and the tank main body portion 20. The head portion 28 has a main body portion integrally formed of a metal material or the like, and a gas flow path 29 penetrating in the axis C1 direction is formed in the main body portion. The "gas distribution route 29" constitutes the "second gas distribution route" in the present embodiment.

取付部27の外周面には、口金23の内周面に形成された雌ネジ部23a〔図2(b)参照〕に螺合する雄ネジ部27aが形成されている。これにより、バルブ25は口金23に対し取付け固定される。 On the outer peripheral surface of the mounting portion 27, a male screw portion 27a to be screwed into the female screw portion 23a [see FIG. 2B] formed on the inner peripheral surface of the base 23 is formed. As a result, the valve 25 is attached and fixed to the base 23.

バルブ25の頭部28は、軸線C1方向に沿って形成された円筒状の本体筒部28aと、該本体筒部28aの軸線C1方向両端部から径方向外側に向け延出形成された円環状のフランジ部28b,28cとを備えている。バルブ25の頭部28は、本実施形態における被接続部材を構成する部位である。 The head 28 of the valve 25 has a cylindrical main body cylinder portion 28a formed along the axis C1 direction and an annular shape extending radially outward from both ends of the main body cylinder portion 28a in the axis C1 direction. The flange portions 28b and 28c of the above are provided. The head portion 28 of the valve 25 is a portion constituting the connected member in the present embodiment.

このうち、後述する接続ユニット30が接合される先端側のフランジ部28b(本体筒部28a)の端面には、ガス流通経路29の開口部周縁に沿って被接合部28dが形成されている。被接合部28dは、ガス流通経路29が開口側に向け徐々に拡径したようなテーパ状の凹部となっている。 Of these, a bonded portion 28d is formed along the peripheral edge of the opening of the gas flow path 29 on the end surface of the flange portion 28b (main body cylinder portion 28a) on the distal end side to which the connection unit 30 described later is bonded. The bonded portion 28d is a tapered recess in which the gas flow path 29 gradually expands in diameter toward the opening side.

バルブ25は、接続ユニット30を介して水素供給用配管LAに接続されている。これにより、ガス流通経路29と水素供給用配管LAとが連通した状態となる。水素供給用配管LAの他端側は、燃料電池システム7の水素ガス供給系に接続されている。これにより、水素供給用配管LAを介して、高圧水素タンク8から燃料電池システム7へ水素ガスを供給可能となる。 The valve 25 is connected to the hydrogen supply pipe LA via the connection unit 30. As a result, the gas flow path 29 and the hydrogen supply pipe LA are in communication with each other. The other end of the hydrogen supply pipe LA is connected to the hydrogen gas supply system of the fuel cell system 7. As a result, hydrogen gas can be supplied from the high-pressure hydrogen tank 8 to the fuel cell system 7 via the hydrogen supply pipe LA.

ここで、接続ユニット30の構成について詳しく説明する。図4(a)~(c)に示すように、接続ユニット30は、水素供給用配管LA及びバルブ25がそれぞれ接続される接続部材31と、該接続部材31とバルブ25の接続状態を維持する維持手段としての連結機構部32とからなる。 Here, the configuration of the connection unit 30 will be described in detail. As shown in FIGS. 4A to 4C, the connection unit 30 maintains a connection member 31 to which the hydrogen supply pipe LA and the valve 25 are connected, and a connection state between the connection member 31 and the valve 25. It includes a connecting mechanism unit 32 as a maintenance means.

接続部材31は、燃料電池自動車1Aを構成する車両プラットフォームに対し、予めブラケット等を介して貯蔵体設置部10の側方位置に取付け固定されると共に、この接続部材31に対し連結機構部32が組み付けられている。 The connection member 31 is attached and fixed to the vehicle platform constituting the fuel cell vehicle 1A in advance via a bracket or the like at a lateral position of the storage body installation portion 10, and the connection mechanism portion 32 is attached to the connection member 31. It is assembled.

図5(a)~(c)に示すように、接続部材31は、軸線C1方向に沿って延びるガス流通経路33を有した円筒状の本体筒部34と、該本体筒部34の軸線C1方向略中央部から径方向外側に向け延出形成された略円環状のフランジ部35とを備え、これらが導電性金属材料により一体形成されている。「ガス流通経路33」が本実施形態における「第1ガス流通経路」を構成する。 As shown in FIGS. 5A to 5C, the connecting member 31 has a cylindrical main body cylinder portion 34 having a gas flow path 33 extending along the axis C1 direction, and an axis line C1 of the main body cylinder portion 34. A substantially annular flange portion 35 extending from a substantially central portion in the direction toward the outer side in the radial direction is provided, and these are integrally formed of a conductive metal material. The "gas distribution route 33" constitutes the "first gas distribution route" in the present embodiment.

本体筒部34には、その先端側(水素供給用配管LAが接続される基端側とは反対側)において、バルブ25側の被接合部28dに接合する接合部34aが形成されている。接合部34aは、本体筒部34が先端側に向け徐々に縮径したようなテーパ状となっている。つまり、被接合部28d及び接合部34aは、所謂コーンアンドスレッド接続構造を有している。また、フランジ部35は、先端側の大径部35aと、基端側の小径部35bとから構成されている。 A joint portion 34a to be joined to the joined portion 28d on the valve 25 side is formed on the main body cylinder portion 34 on the tip end side (the side opposite to the base end side to which the hydrogen supply pipe LA is connected). The joint portion 34a has a tapered shape in which the diameter of the main body cylinder portion 34 is gradually reduced toward the tip end side. That is, the joined portion 28d and the joined portion 34a have a so-called cone-and-thread connection structure. Further, the flange portion 35 is composed of a large diameter portion 35a on the tip end side and a small diameter portion 35b on the base end side.

図6(a)~(c)に示すように、連結機構部32は、軸線C1方向に沿って延びる挿通孔36を有した円筒状のベース部37と、該ベース部37に対し回動変位可能に組付けられた一対のアーム部38とからなる。「アーム部38」が本実施形態における「係合部材」を構成する。 As shown in FIGS. 6A to 6C, the connecting mechanism portion 32 is rotationally displaced with respect to a cylindrical base portion 37 having an insertion hole 36 extending along the axis C1 direction and the base portion 37. It is composed of a pair of arm portions 38 that are possibly assembled. The "arm portion 38" constitutes the "engaging member" in the present embodiment.

挿通孔36の内径は、接続部材31の本体筒部34の外径と略同一径となっている。そして、接続部材31の本体筒部34の基端側を挿通孔36に挿通することで、連結機構部32が接続部材31に対し組付けられている。これにより、連結機構部32は、接続部材31に対し軸線C1方向に沿って摺動可能かつ軸線C1を中心に周方向に変位可能な状態となっている。 The inner diameter of the insertion hole 36 is substantially the same as the outer diameter of the main body cylinder portion 34 of the connecting member 31. Then, the connecting mechanism portion 32 is assembled to the connecting member 31 by inserting the base end side of the main body cylinder portion 34 of the connecting member 31 into the insertion hole 36. As a result, the connecting mechanism portion 32 is in a state where it can slide with respect to the connecting member 31 along the axis C1 direction and can be displaced in the circumferential direction around the axis C1.

ベース部37の外周面には、挿通孔36を挟んで一対の凹部39が形成されており、該各凹部39に対しそれぞれ1つのアーム部38が組付けられている。 A pair of recesses 39 are formed on the outer peripheral surface of the base portion 37 with the insertion hole 36 interposed therebetween, and one arm portion 38 is attached to each of the recesses 39.

アーム部38は、直棒状の本体部38aと、その両端部において鉤状に屈曲形成された先端側屈曲部38b及び基端側屈曲部38cとを有し、これらが導電性金属材料により一体形成され、全体としてコ字状に形成されている。 The arm portion 38 has a straight rod-shaped main body portion 38a, a tip-side bent portion 38b and a base-end-side bent portion 38c that are bent and formed in a hook shape at both ends thereof, and these are integrally formed of a conductive metal material. It is formed in a U shape as a whole.

アーム部38は、その基端側屈曲部38cの先端部がベース部37の凹部39に挿し込まれた状態で、該凹部39内において基端側屈曲部38cの先端部近傍が軸ピン40により軸支されている。これにより、アーム部38は、軸線C1方向と直交する方向に挿し込まれた軸ピン40を軸心としてベース部37に対し回動変位可能となっている。 In the arm portion 38, the tip portion of the base end side bent portion 38c is inserted into the recess 39 of the base portion 37, and the vicinity of the tip portion of the proximal end side bent portion 38c in the recess 39 is formed by the shaft pin 40. It is supported by the axis. As a result, the arm portion 38 can be rotatably displaced with respect to the base portion 37 with the shaft pin 40 inserted in the direction orthogonal to the axis C1 direction as the axis.

尚、本実施形態において、ベース部37は、その本体部が高剛性の金属材料により形成されているが、挿通孔36や凹部39など、少なくともアーム部38や接続部材31と隣接する部位においては、例えば絶縁スペーサを介するなど絶縁処理が施されており、アーム部38と接続部材31との間における電気的導通が遮断された構成となっている。 In the present embodiment, the main body of the base 37 is made of a highly rigid metal material, but at least in a portion adjacent to the arm 38 or the connecting member 31, such as an insertion hole 36 or a recess 39. Insulation treatment is performed, for example, via an insulating spacer, so that the electrical conduction between the arm portion 38 and the connecting member 31 is cut off.

かかる構成の下、燃料電池自動車1Aの製造時において、車両プラットフォームの貯蔵体設置部10に対し高圧水素タンク8を設置する場合には、まず予め車両プラットフォームに取付けられている接続ユニット30の接続部材31に対し、別途用意した水素供給用配管LAを接続固定する。 Under such a configuration, when the high-pressure hydrogen tank 8 is installed in the storage body installation portion 10 of the vehicle platform at the time of manufacturing the fuel cell vehicle 1A, first, the connection member of the connection unit 30 previously attached to the vehicle platform is used. A separately prepared hydrogen supply pipe LA is connected and fixed to 31.

続いて、貯蔵体設置部10に設置した高圧水素タンク8のバルブ25を接続部材31に対し接続する。具体的は、バルブ25の被接合部28dに対し接続部材31の接合部34aを接合する〔図7(a),(b)等参照〕。 Subsequently, the valve 25 of the high-pressure hydrogen tank 8 installed in the storage body installation unit 10 is connected to the connecting member 31. Specifically, the joining portion 34a of the connecting member 31 is joined to the joined portion 28d of the valve 25 [see FIGS. 7 (a), 7 (b), etc.].

次に、接続ユニット30の連結機構部32を、両アーム部38が開いた状態で接続部材31に押し付けつつ、バルブ25を接続部材31に対し押し付ける。 Next, the valve 25 is pressed against the connecting member 31 while pressing the connecting mechanism portion 32 of the connecting unit 30 against the connecting member 31 with both arm portions 38 open.

かかる状態で、両アーム部38を閉じていき、両アーム部38の先端側屈曲部38bをバルブ25の両フランジ部28b,28c間に圧入する。より詳しくは、先端側屈曲部38bの内側面をバルブ25先端側のフランジ部28bの裏側に圧接させつつ、そこから受ける摩擦力に抗して、先端側屈曲部38bを両フランジ部28b,28c間に対し圧力をかけ押し込んでいく。 In this state, both arm portions 38 are closed, and the distal end side bent portion 38b of both arm portions 38 is press-fitted between the flange portions 28b and 28c of the valve 25. More specifically, while the inner side surface of the distal end side bent portion 38b is pressed against the back side of the flange portion 28b on the distal end side of the valve 25, the distal end side bent portion 38b is brought into both flange portions 28b, 28c against the frictional force received from the pressure contact. Apply pressure to the space and push it in.

これにより、先端側屈曲部38bがバルブ25先端側のフランジ部28bの裏側に圧接状態で係止される。かかる状態となると、バルブ25及び接続部材31がアーム部38により挟持されたような状態となり、バルブ25及び接続部材31に対し軸線C1方向に互いに押し付けるような圧力がかかった状態となる。 As a result, the bent portion 38b on the distal end side is locked to the back side of the flange portion 28b on the distal end side of the valve 25 in a pressure contact state. In such a state, the valve 25 and the connecting member 31 are sandwiched by the arm portion 38, and pressure is applied to the valve 25 and the connecting member 31 so as to press each other in the axis C1 direction.

そして、バルブ25のガス流通経路29と接続部材31のガス流通経路33とが連通した状態となり、高圧水素タンク8と水素供給用配管LAの接続作業が完了する。 Then, the gas flow path 29 of the valve 25 and the gas flow path 33 of the connecting member 31 are in communication with each other, and the connection work between the high-pressure hydrogen tank 8 and the hydrogen supply pipe LA is completed.

つまり、「アーム部38の先端側屈曲部38b」が「係合部材の係合部」を構成し、「バルブ25先端側のフランジ部28b」が「被接続部材の被係合部」を構成する。 That is, the "end end side bending portion 38b of the arm portion 38" constitutes the "engagement portion of the engaging member", and the "flange portion 28b on the tip end side of the valve 25" constitutes the "engaged portion of the connected member". do.

ここで、後述する第3実施形態〔図14(a)参照〕のように、アーム部38の先端側屈曲部38bの内側面に半球状の係止凸部68を形成すると共に、これに対応して、フランジ部28bの裏面に係止凸部68が嵌入可能な係止凹部69を形成することにより、先端側屈曲部38bがフランジ部28bの裏側に圧接状態で嵌合する構成としてもよい。 Here, as in the third embodiment described later [see FIG. 14 (a)], a hemispherical locking convex portion 68 is formed on the inner side surface of the distal end side bent portion 38b of the arm portion 38, and the corresponding hemispherical locking convex portion 68 is formed. Then, by forming a locking recess 69 into which the locking convex portion 68 can be fitted on the back surface of the flange portion 28b, the tip side bent portion 38b may be fitted to the back side of the flange portion 28b in a pressure-welded state. ..

接続作業が完了すると、図8、図9(a),(b)に示すように、バルブ25及び接続部材31が軸線C1方向に対し相対変位不能となり、軸線C1方向に対する高圧水素タンク8の位置も固定される。同時に、バルブ25の被接合部28dと接続部材31の接合部34aとが圧接した状態となり、ガス流通経路29,33間の高気密性が維持される。 When the connection work is completed, as shown in FIGS. 8, 9 (a) and 9 (b), the valve 25 and the connecting member 31 cannot be displaced relative to the axis C1 direction, and the position of the high-pressure hydrogen tank 8 with respect to the axis C1 direction. Is also fixed. At the same time, the bonded portion 28d of the valve 25 and the bonded portion 34a of the connecting member 31 are in a state of pressure contact, and high airtightness between the gas flow paths 29 and 33 is maintained.

その後、高圧水素タンク8を図示しないバンド等の固定手段により貯蔵体設置部10に対し固定し、高圧水素タンク8の設置作業を完了する。 After that, the high-pressure hydrogen tank 8 is fixed to the storage body installation portion 10 by a fixing means such as a band (not shown), and the installation work of the high-pressure hydrogen tank 8 is completed.

次に、図1(b)に示す電気自動車1Bについて詳しく説明する。電気自動車1Bは、主要な構成要素として、車体2と、左右一対の前輪3と、左右一対の後輪4と、前輪3を駆動させる電動モータ5と、該電動モータ5への電力供給を制御するPCU6と、電気エネルギーを貯蔵する蓄電池としてのバッテリーパック50と、バッテリーパック50から電動モータ5(PCU6)へ電力を供給する電力供給ラインとしての電気ケーブルLBとを備えている。 Next, the electric vehicle 1B shown in FIG. 1B will be described in detail. The electric vehicle 1B controls the power supply to the vehicle body 2, the pair of left and right front wheels 3, the pair of left and right rear wheels 4, the electric motor 5 for driving the front wheels 3, and the electric motor 5 as main components. It is provided with a PCU 6 to be used, a battery pack 50 as a storage battery for storing electric energy, and an electric cable LB as a power supply line for supplying power from the battery pack 50 to the electric motor 5 (PCU6).

続いて、貯蔵体設置部10に設置されるバッテリーパック50、並びに、これと電気ケーブルLBとを接続する接続構造について説明する。尚、かかる接続構造は、上述した高圧水素タンク8と水素供給用配管LAの接続構造で用いた接続ユニット30を同じく使用するといった点において、上記接続構造と共通する共通接続構造を有している。 Next, the battery pack 50 installed in the storage body installation unit 10 and the connection structure for connecting the battery pack 50 and the electric cable LB will be described. The connection structure has a common connection structure common to the connection structure in that the connection unit 30 used in the connection structure of the high-pressure hydrogen tank 8 and the hydrogen supply pipe LA described above is also used. ..

図10(a)~(c)に示すように、バッテリーパック50は、円筒形状のケース51を有し、その内部に電池要素52が収容されている。 As shown in FIGS. 10A to 10C, the battery pack 50 has a cylindrical case 51 in which the battery element 52 is housed.

バッテリーパック50には、ケース51の軸線C1方向一端部において、電池要素52と電気的に導通可能に接続された端子部材53が設けられている。端子部材53は、接続ユニット30が接続される被接続部材としても機能するものであり、外見上、上記バルブ25の頭部28と略同一形状となっている。 The battery pack 50 is provided with a terminal member 53 electrically conductively connected to the battery element 52 at one end of the case 51 in the axis C1 direction. The terminal member 53 also functions as a connected member to which the connection unit 30 is connected, and has substantially the same shape as the head portion 28 of the valve 25 in appearance.

図11(a),(b)に示すように、端子部材53は、最も径方向外側の外殻部を構成する外層部54と、その径方向内側に配置される中層部55と、さらにその径方向内側に配置される内層部56とを有する3層構造となっている。 As shown in FIGS. 11A and 11B, the terminal member 53 includes an outer layer portion 54 constituting the outermost outer shell portion in the radial direction, a middle layer portion 55 arranged inside the outer layer portion 55 in the radial direction, and further the same. It has a three-layer structure having an inner layer portion 56 arranged inside in the radial direction.

外層部54は、軸線C1方向に沿って形成された円筒状の本体筒部54aと、該本体筒部54aの軸線C1方向両端部から径方向外側に向け延出形成された円環状のフランジ部54b,54cとを備え、これらが導電性金属材料により一体形成されている。 The outer layer portion 54 has a cylindrical main body cylinder portion 54a formed along the axis C1 direction and an annular flange portion formed so as to extend radially outward from both ends of the main body cylinder portion 54a in the axis C1 direction. 54b and 54c are provided, and these are integrally formed of a conductive metal material.

本体筒部54aには、軸線C1方向に貫通する孔部57が形成されている。孔部57は、電池要素52と接続される基端側(フランジ部54c側)において軸線C1方向に沿って真っ直ぐに延びる直孔部57aと、接続ユニット30が接合される先端側(フランジ部54b側)において、開口側に向け徐々に拡径したテーパ孔部57bとから構成されている。 A hole 57 penetrating in the axis C1 direction is formed in the main body cylinder portion 54a. The hole portion 57 has a straight hole portion 57a extending straight along the axis C1 direction on the proximal end side (flange portion 54c side) connected to the battery element 52 and the tip end side (flange portion 54b) to which the connection unit 30 is joined. On the side), it is composed of a tapered hole portion 57b whose diameter is gradually expanded toward the opening side.

中層部55は、外層部54の孔部57に対し嵌め込み可能なように、その外側形状が孔部57の内側形状と略同一形状となるよう構成され、絶縁材料により全体として漏斗状に形成されている。また、中層部55の内部には、軸線C1方向に貫通する孔部58が形成されている。孔部58は、基端側において軸線C1方向に沿って真っ直ぐに延びる直孔部58aと、先端側において、開口側に向け徐々に拡径したテーパ孔部58bとから構成されている。 The middle layer portion 55 is configured so that its outer shape is substantially the same as the inner shape of the hole portion 57 so that it can be fitted into the hole portion 57 of the outer layer portion 54, and is formed into a funnel shape as a whole by an insulating material. ing. Further, inside the middle layer portion 55, a hole portion 58 penetrating in the axis C1 direction is formed. The hole portion 58 is composed of a straight hole portion 58a extending straight along the axis C1 direction on the proximal end side, and a tapered hole portion 58b gradually increasing in diameter toward the opening side on the distal end side.

内層部56は、中層部55の孔部58に対し嵌め込み可能なように、その外側形状が孔部58の内側形状と略同一形状となるよう、導電性金属材料により一体形成されている。また、内層部56の先端側の端面には、上記接続ユニット30の接合部34aが接合される被接合部59が形成されている。被接合部59は、接合部34aのテーパ形状に対応して、開口側に向け徐々に拡径したテーパ状の凹部となっている。つまり、被接合部59及び接合部34aは、所謂コーンアンドスレッド接続構造を有している。 The inner layer portion 56 is integrally formed of a conductive metal material so that its outer shape is substantially the same as the inner shape of the hole portion 58 so that it can be fitted into the hole portion 58 of the middle layer portion 55. Further, a bonded portion 59 to which the bonded portion 34a of the connecting unit 30 is bonded is formed on the end surface of the inner layer portion 56 on the distal end side. The jointed portion 59 is a tapered concave portion whose diameter gradually increases toward the opening side, corresponding to the tapered shape of the joined portion 34a. That is, the joined portion 59 and the joined portion 34a have a so-called cone-and-thread connection structure.

そして、端子部材53のうち、外層部54の基端側が電池要素52の図示しない正極端子と電気的に導通可能に接続され、内層部56の基端側が電池要素52の図示しない負極端子と電気的に導通可能に接続されている。 Then, in the terminal member 53, the proximal end side of the outer layer portion 54 is electrically conductively connected to the positive electrode terminal (not shown) of the battery element 52, and the proximal end side of the inner layer portion 56 is electrically connected to the negative electrode terminal (not shown) of the battery element 52. It is connected so that it can be electrically conducted.

さらに、図12(a)~(c)に示すように、バッテリーパック50の端子部材53は、上記接続ユニット30を介して電気ケーブルLBと電気的に導通可能に接続されている。一方、電気ケーブルLBの他端側は、電動モータ5(PCU6)に電気的に導通可能に接続されている。これにより、電気ケーブルLBを介して、バッテリーパック50から電動モータ5へ電力供給可能となる。 Further, as shown in FIGS. 12A to 12C, the terminal member 53 of the battery pack 50 is electrically conductively connected to the electric cable LB via the connection unit 30. On the other hand, the other end side of the electric cable LB is electrically conductively connected to the electric motor 5 (PCU6). As a result, electric power can be supplied from the battery pack 50 to the electric motor 5 via the electric cable LB.

かかる構成の下、電気自動車1Bの製造時において、車両プラットフォームの貯蔵体設置部10に対しバッテリーパック50を設置する場合には、まず予め車両プラットフォームに取付けられている接続ユニット30に対し、別途用意した電気ケーブルLBを電気的に導通可能に接続する。 Under such a configuration, when the battery pack 50 is installed in the storage body installation portion 10 of the vehicle platform at the time of manufacturing the electric vehicle 1B, first, the connection unit 30 previously attached to the vehicle platform is separately prepared. The electric cable LB is electrically connected so as to be electrically conductive.

具体的には、接続ユニット30のうち、接続部材31を電気ケーブルLB内の負極配線(図示略)と電気的に導通可能に接続し、アーム部38を電気ケーブルLB内の正極配線(図示略)と電気的に導通可能に接続する。従って、「接続ユニット30」のうち「接続部材31」が本実施形態における「第1電気導通経路」を構成し、「アーム部38」が本実施形態における「第3電気導通経路」を構成する。 Specifically, of the connection unit 30, the connection member 31 is electrically conductively connected to the negative electrode wiring (not shown) in the electric cable LB, and the arm portion 38 is electrically conductively connected to the positive electrode wiring (not shown) in the electric cable LB. ) And electrically connectable. Therefore, of the "connection unit 30", the "connection member 31" constitutes the "first electrical conduction path" in the present embodiment, and the "arm portion 38" constitutes the "third electrical conduction path" in the present embodiment. ..

これにより、接続ユニット30と電気ケーブルLBが電気的に導通した状態となる。具体的には、接続部材31と負極配線が電気的に導通した状態となると共に、アーム部38と正極配線が電気的に導通した状態となる。 As a result, the connection unit 30 and the electric cable LB are in a state of being electrically conductive. Specifically, the connection member 31 and the negative electrode wiring are in a state of being electrically conductive, and the arm portion 38 and the positive electrode wiring are in a state of being electrically conductive.

続いて、貯蔵体設置部10に設置したバッテリーパック50の端子部材53を接続部材31に対し接続する。具体的は、端子部材53の被接合部59に対し接続部材31の接合部34aを接合する。 Subsequently, the terminal member 53 of the battery pack 50 installed in the storage body installation unit 10 is connected to the connection member 31. Specifically, the joining portion 34a of the connecting member 31 is joined to the joined portion 59 of the terminal member 53.

次に、接続ユニット30の連結機構部32を、両アーム部38が開いた状態で接続部材31に押し付けつつ、端子部材53を接続部材31に対し押し付ける。 Next, the terminal member 53 is pressed against the connecting member 31 while pressing the connecting mechanism portion 32 of the connecting unit 30 against the connecting member 31 with both arm portions 38 open.

かかる状態で、両アーム部38を閉じていき、両アーム部38の先端側屈曲部38bを端子部材53(外層部54)の両フランジ部54b,54c間に圧入する。より詳しくは、先端側屈曲部38bの内側面を端子部材53先端側のフランジ部54bの裏側に圧接させつつ、そこから受ける摩擦力に抗して、先端側屈曲部38bを両フランジ部54b,54c間に対し圧力をかけ押し込んでいく。 In this state, both arm portions 38 are closed, and the distal end side bent portion 38b of both arm portions 38 is press-fitted between the flange portions 54b and 54c of the terminal member 53 (outer layer portion 54). More specifically, while the inner side surface of the distal end side bent portion 38b is pressed against the back side of the flange portion 54b on the distal end side of the terminal member 53, the distal end side bent portion 38b is brought into both flange portions 54b against the frictional force received from the pressure contact. Pressure is applied between 54c and pushed.

これにより、先端側屈曲部38bが端子部材53先端側のフランジ部54bの裏側に圧接状態で係止される。かかる状態となると、端子部材53及び接続部材31がアーム部38により挟持されたような状態となり、端子部材53及び接続部材31に対し軸線C1方向に互いに押し付けるような圧力がかかった状態となる。 As a result, the bent portion 38b on the distal end side is locked to the back side of the flange portion 54b on the distal end side of the terminal member 53 in a pressure-welded state. In such a state, the terminal member 53 and the connecting member 31 are sandwiched by the arm portion 38, and pressure is applied to the terminal member 53 and the connecting member 31 so as to press each other in the axis C1 direction.

そして、端子部材53のうち、外層部54がアーム部38と電気的に導通可能に接続されると共に、内層部56が接続部材31と電気的に導通可能に接続された状態となり、バッテリーパック50と電気ケーブルLBの接続作業が完了する。 Then, among the terminal members 53, the outer layer portion 54 is electrically conductively connected to the arm portion 38, and the inner layer portion 56 is electrically conductively connected to the connection member 31. And the connection work of the electric cable LB is completed.

つまり、「アーム部38の先端側屈曲部38b」が「係合部材の係合部」を構成し、「端子部材53の先端側のフランジ部54b」が「被接続部材の被係合部」を構成する。また、「内層部56」が本実施形態における「第2電気導通経路」を構成し、「外層部54」が本実施形態における「第4電気導通経路」を構成する。 That is, the "end end side bending portion 38b of the arm portion 38" constitutes the "engagement portion of the engaging member", and the "flange portion 54b on the tip end side of the terminal member 53" is the "engaged portion of the connected member". To configure. Further, the "inner layer portion 56" constitutes the "second electrical conduction path" in the present embodiment, and the "outer layer portion 54" constitutes the "fourth electrical conduction path" in the present embodiment.

ここで、後述する第3実施形態〔図14(b)参照〕のように、アーム部38の先端側屈曲部38bの内側面に半球状の係止凸部68を形成すると共に、これに対応して、フランジ部54bの裏面に係止凸部68が嵌入可能な係止凹部70を形成することにより、先端側屈曲部38bがフランジ部54bの裏側に圧接状態で嵌合する構成としてもよい。 Here, as in the third embodiment described later [see FIG. 14 (b)], a hemispherical locking convex portion 68 is formed on the inner side surface of the distal end side bent portion 38b of the arm portion 38, and the corresponding hemispherical locking convex portion 68 is formed. Then, by forming a locking recess 70 into which the locking convex portion 68 can be fitted on the back surface of the flange portion 54b, the tip side bent portion 38b may be fitted to the back side of the flange portion 54b in a pressure-welded state. ..

接続作業が完了すると、端子部材53及び接続部材31が軸線C1方向に対し相対変位不能となり、軸線C1方向に対するバッテリーパック50の位置も固定される。同時に、端子部材53の被接合部59と接続部材31の接合部34aが圧接した状態となると共に、アーム部38の先端側屈曲部38bと端子部材53のフランジ部54bとが圧接した状態となる。これにより、端子部材53と接続ユニット30の間の導電性が適切な状態に維持される。 When the connection work is completed, the terminal member 53 and the connection member 31 cannot be displaced relative to the axis C1 direction, and the position of the battery pack 50 with respect to the axis C1 direction is also fixed. At the same time, the jointed portion 59 of the terminal member 53 and the jointed portion 34a of the connecting member 31 are in a state of being in pressure contact with each other, and the tip end side bent portion 38b of the arm portion 38 and the flange portion 54b of the terminal member 53 are in a state of pressure contact. .. As a result, the conductivity between the terminal member 53 and the connection unit 30 is maintained in an appropriate state.

その後、バッテリーパック50を図示しないバンド等の固定手段により貯蔵体設置部10に対し固定し、バッテリーパック50の設置作業を完了する。 After that, the battery pack 50 is fixed to the storage body installation portion 10 by a fixing means such as a band (not shown), and the installation work of the battery pack 50 is completed.

以上詳述したように、本実施形態によれば、ガス流通経路33及び電気導通経路を有し、水素供給用配管LA又は電気ケーブルLBのいずれにも接続可能な接続部材31を備えると共に、これと接続可能な共通構造(バルブ25の頭部28や端子部材53)を高圧水素タンク8及びバッテリーパック50のいずれにも共通して備えることにより、供給ラインの接続構造の共通化を図ることができる。 As described in detail above, according to the present embodiment, the connection member 31 which has a gas flow path 33 and an electric conduction path and can be connected to either the hydrogen supply pipe LA or the electric cable LB is provided, and the connection member 31 is provided. By providing a common structure (head 28 of the valve 25 and terminal member 53) that can be connected to both the high-pressure hydrogen tank 8 and the battery pack 50 in common, it is possible to standardize the connection structure of the supply line. can.

このように供給ラインの接続構造を共通化することで、車両1A,1Bの製造時において、車両プラットフォームの貯蔵体設置部10に対し高圧水素タンク8又はバッテリーパック50のいずれか一方を選択して設置可能となると共に、設置された高圧水素タンク8又はバッテリーパック50に応じて、水素供給用配管LA又は電気ケーブルLBのいずれか一方を選択して接続可能となり、車両プラットフォームを共通化することができる。 By sharing the connection structure of the supply line in this way, either the high-pressure hydrogen tank 8 or the battery pack 50 is selected for the storage body installation portion 10 of the vehicle platform at the time of manufacturing the vehicles 1A and 1B. It can be installed, and depending on the installed high-pressure hydrogen tank 8 or battery pack 50, either the hydrogen supply pipe LA or the electric cable LB can be selected and connected, and the vehicle platform can be shared. can.

ひいては、車両プラットフォームに対し、予めガス供給系統と電力供給系統の2系統を設置しておく必要もなく、部品点数の増加抑制、構造の簡素化、省スペース化及びコストの削減等を図ることができる。 As a result, it is not necessary to install two systems, a gas supply system and a power supply system, in advance for the vehicle platform, and it is possible to suppress the increase in the number of parts, simplify the structure, save space, and reduce costs. can.

また、車両プラットフォームに設置される高圧水素タンク8又はバッテリーパック50に応じて、接続部材31の交換を行う必要もなく、同一の接続部材31を用いることで、該接続部材31等を車両プラットフォームに固定する固定構造も共通化することができる。 Further, it is not necessary to replace the connecting member 31 according to the high-pressure hydrogen tank 8 or the battery pack 50 installed on the vehicle platform, and by using the same connecting member 31, the connecting member 31 or the like can be used as the vehicle platform. The fixed structure to be fixed can also be standardized.

加えて、連結機構部32を備えることにより、接続部材31と高圧水素タンク8側のバルブ25とを接続する場合には、接合部34aと被接合部28dとの間におけるシール性を適切に維持することができ、接続部材31とバッテリーパック50側の端子部材53とを接続する場合には、接合部34aと被接合部59との間における電気導通性を適切に維持することができる。 In addition, by providing the connecting mechanism portion 32, when the connecting member 31 and the valve 25 on the high pressure hydrogen tank 8 side are connected, the sealing property between the joint portion 34a and the bonded portion 28d is appropriately maintained. When the connection member 31 and the terminal member 53 on the battery pack 50 side are connected, the electrical conductivity between the joint portion 34a and the jointed portion 59 can be appropriately maintained.

尚、本実施形態では、バルブ25(又は端子部材53)と接続部材31とを圧接状態で接続するにあたり、一対のアーム部38がベース部37に対し回動変位可能に組付けられた連結機構部32を用いる構成となっているが、これに代えて、ベース部37を省略し、アーム部38のみで、バルブ25(又は端子部材53)と接続部材31とを圧接状態で接続する構成を採用してもよい。 In this embodiment, when the valve 25 (or the terminal member 53) and the connecting member 31 are connected by pressure contact, a pair of arm portions 38 are rotatably and displaceably assembled with respect to the base portion 37. Although the configuration is such that the portion 32 is used, instead of this, the base portion 37 is omitted, and the valve 25 (or the terminal member 53) and the connecting member 31 are connected in a pressure-welded state only by the arm portion 38. It may be adopted.

例えば、バルブ25(又は端子部材53)と接続部材31とを押し付けた状態の組付体に対し、アーム部38を、その先端側屈曲部38bがバルブ25先端側のフランジ部28b(又は端子部材53先端側のフランジ部54b)の裏側に係止され、かつ、その基端側屈曲部38cが接続部材31のフランジ部35の裏側に係止されるように、軸線C1方向と直交する方向に圧入する。 For example, the arm portion 38 is attached to the assembled body in which the valve 25 (or the terminal member 53) and the connecting member 31 are pressed against each other, and the distal end side bending portion 38b thereof is the flange portion 28b (or the terminal member) on the distal end side of the valve 25. In a direction orthogonal to the axis C1 direction so as to be locked to the back side of the flange portion 54b) on the tip end side and to be locked to the back side of the flange portion 35 of the connecting member 31 at the base end side bent portion 38c.

つまり、先端側屈曲部38bの内側面をバルブ25先端側のフランジ部28b(又は端子部材53先端側のフランジ部54b)の裏側に圧接させつつ、かつ、基端側屈曲部38cの内側面を接続部材31のフランジ部35の裏側に圧接させつつ、そこから受ける摩擦力に抗して、アーム部38を上記組付体に対し軸線C1方向と直交する方向に圧力をかけ押し込んでいく。 That is, the inner surface of the bent portion 38b on the distal end side is pressed against the back side of the flange portion 28b on the distal end side of the valve 25 (or the flange portion 54b on the distal end side of the terminal member 53), and the inner surface of the bent portion 38c on the proximal end side is pressed. While pressing against the back side of the flange portion 35 of the connecting member 31, the arm portion 38 is pushed against the assembled body by applying pressure in a direction orthogonal to the axis C1 direction against the frictional force received from the pressure contact.

そして、アーム部38の組付けが完了すると、先端側屈曲部38bがバルブ25先端側のフランジ部28b(又は端子部材53先端側のフランジ部54b)の裏側に圧接状態で係止されると共に、基端側屈曲部38cが接続部材31のフランジ部35の裏側に圧接状態で係止された状態となる。 When the assembly of the arm portion 38 is completed, the bent portion 38b on the distal end side is locked to the back side of the flange portion 28b on the distal end side of the valve 25 (or the flange portion 54b on the distal end side of the terminal member 53) in a pressure contact state. The base end side bent portion 38c is in a state of being locked to the back side of the flange portion 35 of the connecting member 31 in a pressure contact state.

かかる状態となると、バルブ25(又は端子部材53)と接続部材31とがアーム部38により挟持されたような状態となり、バルブ25(又は端子部材53)と接続部材31に対し軸線C1方向に互いに押し付けるような圧力がかかった状態となる。 In such a state, the valve 25 (or the terminal member 53) and the connecting member 31 are sandwiched by the arm portion 38, and the valve 25 (or the terminal member 53) and the connecting member 31 are connected to each other in the axis C1 direction. It will be in a state where pressure is applied.

勿論、ここで上記同様に、後述する第3実施形態〔図14(a),(b)参照〕のように、アーム部38の先端側屈曲部38b及び基端側屈曲部38cの内側面にそれぞれ半球状の係止凸部を形成すると共に、これに対応して、バルブ25先端側のフランジ部28b(又は端子部材53先端側のフランジ部54b)及び接続部材31のフランジ部35の裏側にそれぞれ前記係止凸部が嵌入可能な係止凹部を形成することにより、先端側屈曲部38b及び基端側屈曲部38cがそれぞれバルブ25先端側のフランジ部28b(又は端子部材53先端側のフランジ部54b)及び接続部材31のフランジ部35の裏側に圧接状態で嵌合する構成としてもよい。 Of course, similarly to the above, as in the third embodiment described later [see FIGS. 14 (a) and 14 (b)], on the inner surface of the distal end side bent portion 38b and the proximal end side bent portion 38c of the arm portion 38. Each hemispherical locking convex portion is formed, and correspondingly, on the back side of the flange portion 28b on the tip side of the valve 25 (or the flange portion 54b on the tip side of the terminal member 53) and the flange portion 35 of the connecting member 31. By forming a locking recess into which the locking convex portion can be fitted, the distal end side bent portion 38b and the proximal end side bent portion 38c are respectively the flange portion 28b on the distal end side of the valve 25 (or the flange on the distal end side of the terminal member 53). It may be configured to be fitted to the back side of the flange portion 35 of the portion 54b) and the connecting member 31 in a pressure-welded state.

Next, the fourth embodiment will be described in detail with reference to the drawings. In the present embodiment, instead of the locking convex portion 68 according to the third embodiment, the arm portion 38 is provided with a rotatable member.

具体的には、図15(a)に示すように、アーム部38の先端側屈曲部38bの内側面に凹部75が形成され、該凹部75内にローラー76が収容されている。ローラー76は、軸ピン77により回転可能に軸支されると共に、その一部が先端側屈曲部38bの内側面から突出している。 Specifically, as shown in FIG. 15A, a recess 75 is formed on the inner surface of the bent portion 38b on the distal end side of the arm portion 38, and the roller 76 is housed in the recess 75. The roller 76 is rotatably supported by a shaft pin 77, and a part thereof protrudes from the inner surface of the distal end side bent portion 38b.

これに対応して、先端側屈曲部38bが係合する被係合部(例えばバルブ25のフランジ部28bの裏面や、端子部材53のフランジ部54bの裏面)には、図17(a),(b)に示すように、それぞれローラー76が係合可能な断面円弧状の環状溝部79,80が形成されている。 Correspondingly, the engaged portion (for example, the back surface of the flange portion 28b of the valve 25 and the back surface of the flange portion 54b of the terminal member 53) with which the distal end side bent portion 38b is engaged is marked with FIG. As shown in (b), annular groove portions 79 and 80 having an arcuate cross section with which the rollers 76 can be engaged are formed.

図16(a),(b)に示すように、環状溝部79は、フランジ部28bの周縁部に沿って、フランジ部28bの周方向全域に形成されている。これにより、ローラー76が、フランジ部28bの径方向に対し係合可能な構成となると共に、フランジ部28bの周方向に対しては摺動可能な構成となる。尚、図16(a),(b)では、簡素化のため、バルブ25の頭部28のみを図示している。 As shown in FIGS. 16A and 16B, the annular groove portion 79 is formed in the entire circumferential direction of the flange portion 28b along the peripheral edge portion of the flange portion 28b. As a result, the roller 76 is configured to be engageable with respect to the radial direction of the flange portion 28b, and is also configured to be slidable with respect to the circumferential direction of the flange portion 28b. In FIGS. 16A and 16B, only the head 28 of the valve 25 is shown for simplification.

また、図示は省略するが、端子部材53のフランジ部54bの裏面に形成される環状溝部80に関しても、環状溝部79と同様に、フランジ部54bの周縁部に沿って、フランジ部54bの周方向全域に形成されている。 Although not shown, the annular groove portion 80 formed on the back surface of the flange portion 54b of the terminal member 53 is also provided in the circumferential direction of the flange portion 54b along the peripheral edge portion of the flange portion 54b, similarly to the annular groove portion 79.

For example, as shown in FIG. 15B, an internal space 83 is formed in the bent portion 38b on the distal end side of the arm portion 38, and the ball 84 is housed in the internal space 83 so as not to fall off. The ball 84 is rotatably supported in the internal space 83, and a part of the ball 84 projects outward through an opening formed on the inner surface of the distal end side bent portion 38b.

これにより、本実施形態によれば、上記第2実施形態の作用効果に加え、接続部材31及び被接続部材(バルブ25や端子部材53)の接続作業を行う際、アーム部38の誘導性を高めると共に、接続部材31及び被接続部材の相対位置関係が接続方向(軸線C1方向)を軸心に周方向へ変化してしまった場合でも適切に接続することができる。 As a result, according to the present embodiment, in addition to the operation and effect of the second embodiment, the inductiveness of the arm portion 38 is increased when the connecting member 31 and the connected member (valve 25 and terminal member 53) are connected. At the same time, even if the relative positional relationship between the connecting member 31 and the connected member changes in the circumferential direction around the connecting direction (axis C1 direction), the connection can be appropriately connected.

結果として、接続作業性の向上を図ることができると共に、接続後において接続部材31及び被接続部材の周方向における相対位置関係の位置調整を行うことも可能となる。 As a result, it is possible to improve the connection workability and to adjust the relative positional relationship between the connecting member 31 and the connected member in the circumferential direction after the connection.

In the present embodiment, as a urging means (maintenance means) for urging the connecting member 31 of the connecting unit 30 to the connected member (valve 25 or terminal member 53), the coil spring 66 of the second embodiment or the like is used. The vehicle platform is equipped with an alternative mechanism.

具体的には、図23(a),(b)に示すように、車両プラットフォームにおいて揺動操作可能に設けられた操作レバー200と、接続ユニット30の連結機構部32におけるベース部37の基端側の設けられたコ字状のハンドル部201と、該ハンドル部201と操作レバー200とを連結する連結部材203とを備えている。 Specifically, as shown in FIGS. 23 (a) and 23 (b), the operating lever 200 provided so as to be swingable on the vehicle platform and the base end of the base portion 37 in the connecting mechanism portion 32 of the connecting unit 30. It includes a U-shaped handle portion 201 provided on the side, and a connecting member 203 that connects the handle portion 201 and the operating lever 200.

操作レバー200には、所定方向への動きのみを許容し反対方向への動きを規制する機構(例えばラチェット機構など)や、その規制を解除する機構などが設けられている。本実施形態では、高圧水素タンク8側〔図23左方向〕への動きを規制し、その反対側〔図23右方向〕へ動きを許容するように構成されている。 The operating lever 200 is provided with a mechanism that allows only movement in a predetermined direction and regulates movement in the opposite direction (for example, a ratchet mechanism), a mechanism that releases the regulation, and the like. In the present embodiment, the movement to the 8 side of the high-pressure hydrogen tank [to the left in FIG. 23] is restricted, and the movement to the opposite side [to the right in FIG. 23] is allowed.

When the connection work is completed, the jointed portion 28d of the valve 25 and the jointed portion 34a of the connecting member 31 are in a state of pressure contact, and high airtightness between the gas flow paths 29 and 33 is maintained.

その後、高圧水素タンク8を図示しないバンド等の固定手段により貯蔵体設置部10に対し固定し、高圧水素タンク8の設置作業を完了する。尚、バッテリーパック50の設置作業に関しても同様であるため、詳細な説明は省略する。 After that, the high-pressure hydrogen tank 8 is fixed to the storage body installation portion 10 by a fixing means such as a band (not shown), and the installation work of the high-pressure hydrogen tank 8 is completed. Since the same applies to the installation work of the battery pack 50, detailed description thereof will be omitted.

これにより、本実施形態によれば、上記第1実施形態の作用効果に加え、高圧水素タンク8の接続状態の安定性を高めると共に、バルブ25と接続ユニット30との間の気密性能や、端子部材53と接続ユニット30との間の導電性能の低下抑制を図ることができる。 As a result, according to the present embodiment, in addition to the operation and effect of the first embodiment, the stability of the connection state of the high-pressure hydrogen tank 8 is enhanced, the airtightness between the valve 25 and the connection unit 30 and the terminals are increased. It is possible to suppress the deterioration of the conductive performance between the member 53 and the connection unit 30.
