Description
図1に示されるように、本実施形態の高圧容器搭載構造が適用された車両10は、駆動源となる図示しないモータを備えている。モータは、直接又は減速ギヤ列等の変速手段を介して間接的に車両10の駆動輪(前輪102及び後輪104の少なくとも一方)へ機械的に接続されている。これにより、モータから出力された駆動力が駆動輪へ伝わるようになっている。
車両10の車両下部には、前輪102と後輪104との間にカバー部材としてのケース12が配置されている。より具体的には、ケース12は、車室床部を構成するフロアパネル106の下方側に適用されている。
ここで、上述したケース12の下面部16には、隆起部としての複数のビード20(図3において20A、20B、20C)が設けられている。それぞれのビード20は、下面部16を車両上方側に隆起させて形成され、略水平方向に延在する下面部16の一般面16Aよりも上方側へ凸をなしている。また、複数のビード20は、平面視で車両前後方向に延在する長尺状に形成され、車両幅方向に所定の間隔を空けて配置されている。本実施形態では、隣り合って配置された容器本体30の間に一つずつビード20が配置されている。これにより、下面部16全体の断面2次モーメントが大きくなり、剛性が高められている。
ところで、通常は、連通口22に蓋部材24が取り付けられており、路面から飛散した小石等がケース12の内部に侵入することを防止している。この蓋部材24は、連通口22よりも一回り大きな板状に形成され、連通口22の縁を蓋部材24の周縁部に形成された溝に嵌め込むことにより取り付けられている。この蓋部材24は、蓋部材24の融点がケース12の下面部16の融点よりも低くなる材料を用いて形成されている。本実施形態では、蓋部材24が、燃焼性を有する樹脂材料で形成されている。
図2に示されるように、ケース12の内部には、複数の容器本体30が配置されている。それぞれの容器本体30は、車両前後方向を軸方向として延在されており、略円筒状に形成されている。そして、これらの容器本体30は、高圧ガスとしての水素ガスを収容できるように構成されている。
ここで、容器本体30の軸方向の一端側(車両前方側)の端部に口金32が取り付けられており、口金32に配管としてのマニホールド34が接続されている。マニホールド34は、車両幅方向を長手方向として周壁部18の前壁18Aに沿って延在されており、複数の容器本体30の内部空間を連通する一般流路34Aを備えている。また、マニホールド34の長手方向の中央部にはバルブ36が設けられており、容器本体30とケース12の外部に設けられたバルブ36とが一般流路34Aで連通されている。このバルブ36は、容器本体30の開閉を行う機能を備える開閉弁であり、パイプ等の接続手段を介して上述した燃料電池スタック(図示省略)へ接続されている。そして、バルブ36の開閉を調節することにより、容器本体30から燃料電池スタックへ供給される水素ガスの供給量が調節されるように構成されている。
溶栓弁50は、本体部52と、横栓54と、縦栓56と、コイルバネ58と、感熱部60を主要な構成として備えている。本体部52は、略円柱状に形成されており、内部に筒状の空洞をなす横筒部52A及び縦筒部52Bが形成されている。横筒部52Aは、車両前後方向に延在しており、排ガス流路34Bにおける横流路34B1の後端部に接続されている。一方、縦筒部52Bは、横筒部52Aと直交し、車両上下方向に延在している。
(作用)
次に、本実施形態の作用を説明する。
図7に示されるように、本変形例に係る高圧容器搭載構造では、車両10の下部の車両幅方向の右側端部及び左側端部に溶栓弁50が配置されている。また、溶栓弁50は、マニホールド34における一般流路34Aの車両幅方向の右側端部及び左側端部からそれぞれ分岐した図示しない排ガス流路を閉塞している。なお、当該排ガス流路は、上記した排ガス流路34Bの構成と同様である。
上記実施形態及び変形例では、箱状のケース12がカバー部材とされていたが、これに限らない。カバー部材は、少なくとも容器本体30及びマニホールド34を車両下方側から覆う構成であればよく、例えば、周壁部18及び上面部14を備えず、カバー部材を下面部16のみで構成してもよい。
