Abstract
【解決手段】車両であって、ガスが収容され、車両の前後方向に並べられた複数のタンクを備え、タンクは、それぞれ、予め定められた温度以上になったときに開弁する安全弁と、安全弁の開弁に伴ってタンク内のガスを予め定められた方向に放出する放出部とを備え、複数のタンクの内の前方に配置された前方側タンクの放出部から放出されるガスの放出方向が、前方側タンクよりも後方に配置された後方側タンクの安全弁と地面との間の空間を直接向く方向に設定されている。
【選択図】図1
Description
図1は、本発明の一実施形態における車両100の概略構成を示す説明図である。車両100は、前輪FWと、後輪RWと、複数のタンク10a、10b、10cとを有している。なお、搭載されるタンクの数は、任意に設定可能である。本実施形態では、車両100は燃料電池車両である。車両100は、燃料電池スタックFCを電力源として搭載し、動力源であるモータ(図示せず)が駆動することにより、前輪FWおよび後輪RWのうち少なくとも一方が駆動される。燃料電池スタックFCは、固体高分子形燃料電池であり、空気の供給と各タンク10a、10b、10cから水素ガスの供給とを受けて発電する。
図4は、第2実施形態における車両100Aの概略構成を示す説明図である。本実施形態において、前方側タンクであるタンク10aの放出部31は車両100Aの左側方向(−y軸方向)に延びる筒状のガス放出パイプ13を備えている。図4に示すように、ガス放出パイプ13のガス放出口13aは、車両100Aを上方から見た場合において、タンク10bおよびタンク10cの安全弁30を結ぶ範囲に向けられている。
<第1変形例>
図6は、第1変形例におけるタンク10のガス放出時の車両100Bの側面図である。上記実施形態において、鉛直方向(z軸方向)においてタンク10bはタンク10cよりも下方に設置されている。これに対して、鉛直方向(z軸方向)においてタンク10cはタンク10bよりも下方に設置されていてもよい。本変形例では、図6中に斜線部で示したように、タンク10aの放出部31から放出されるガスの放出方向が、タンク10aの鉛直下向きからタンク10cの外径の接線の範囲内に設定されている。また、タンク10bとタンク10cは鉛直方向(z軸方向)において同じ高さに設置されていてもよい。
上記実施形態において、車両100は2つの後方側タンクである、タンク10b、10cを備えている。これに対して車両100は、後方側タンクを1つのみ備えていてもよい。また、上記実施形態では、前方側タンクであるタンク10aが、長尺方向が車両100の前後方向に沿うように配置されている。これに対して、タンク10aは、タンク10b、10cと同様に車両100の左右方向に沿って配置されていてもよい。そのほか、タンク10aが車両100の左右方向に沿って配置され、タンク10b、10cが車両100の前後方向に沿って配置されてもよい。また、タンク10bとタンク10cとは異なる方向に沿って配置されてもよい。
上記実施形態において、図2に示した安全弁30の構造は一例であり、安全弁30の構造は、予め定められた温度以上になったときに開弁する構造であれば任意の構造を採用可能である。
上記実施形態において、車両100、100Aは燃料電池車両であり、タンク10には燃料ガスである水素ガスが収容されていたが、これに限定されるものではない。例えば、車両100、100Aは液化石油ガスを燃料とするLPG自動車であってもよい。この場合、タンク10には燃料ガスであるLPガスが収容される。
