<<第1実施形態>>
図1は、本発明の第1実施形態に係る車両の燃料タンク1の開口部1kをシールする構造を示す断面図である。
第1実施形態に係る四輪等の車両の燃料タンク1は、その開口部1kが蓋を構成するポンプモジュール3の蓋本体3fで閉塞され、シールされる構造である。
燃料タンク1は、ポンプモジュール3で閉塞される円形の開口部1k近くに円筒部1dが形成されている。円筒部1dは、材料が外方に向かって径方向に二重に折り曲げて燃料タンク1と一体に形成されている。
このように、シール部1bは、図1に示す如く、円筒部1dが径方向の材料を二重にして形成されることにより、強度が高く構成されている。
ポンプモジュール3は、燃料タンク1の開口部1kを閉塞する蓋本体3fと、Oリング等のシール部材2が収容されるシール収容凹部3sと、燃料タンク1の被ロック部1aとシール部1bとが嵌入されるリング状の凹形状の嵌合凹部3k(図1参照)と、燃料タンク1の被ロック部1aに係合するロック部3rとを有する形状に樹脂で形成されている。
ポンプモジュール3のシール収容凹部3sは、Oリング等のシール部材2が収容されるべく、ポンプモジュール3の蓋本体3fの外周に沿って凹形状の横断面を有し、リング状に形成されている。
なお、ロック部3rの数は任意であり限定されないが、ポンプモジュール3等の蓋体が燃料タンク1に蝶番をもって取り付けられた場合には、単数でもよい。この場合、蓋体にポンプを一体に構成しなくともよい。
燃料タンク1を成形するブロー成形に際し、燃料タンク1の開口部1k近くにおいて、燃料タンク1の外側から内側に向けて第2の金型K2を第1の金型K1の方向に押し付けることにより、被ロック部1aとシール面1b1をもつシール部1bとを有する円筒部1dが成形される。
図3(a)に示すように、燃料タンク1(図1参照)をブロー成形するに際し、燃料タンク1の円筒部1dを形成するためのキャビティc1、c2をそれぞれ有する第1の金型K1と第2の金型K2とを配置する。
続いて、図3(c)の矢印α1のように第1の金型K1を押し付ける(移動する)ことにより、燃料タンク1の円筒部1dの形状を形成し、パリソン1pを冷却して固化する。
これにより、燃料タンク1をブロー成形するに際して、燃料タンク1と一体に被ロック部1aとシール部1bとを有する二重形状の円筒部1dが成形される。図3(a)~(e)に示す第1の金型K1と第2の金型K2の金型移動の効果として、型への転写性が向上する。
図4(a)、(b)は、燃料タンク1の開口部1kに、ポンプモジュール3を取り付ける過程を示す側断面図である。
すると、ポンプモジュール3の複数のロック部3rが、燃料タンク1の被ロック部1aの外面に当接して外方に弾性変形する。
さらに、燃料タンク1の開口部1kにポンプモジュール3を、シール部材2を介して嵌入して、燃料タンク1とポンプモジュール3とを係合してロックする構造のため、燃料タンク1のシール構造周りの部品の寸法管理が容易である。
従って、燃料タンク1のシール構造の品質が安定化し、かつ、燃料タンク1へのポンプモジュール3の組付け性が向上する車両が実現できる。
図5は、第2実施形態に係る四輪等の車両の燃料タンク21の開口部21kをシールする構造を示す断面図である。
第2実施形態の四輪等の車両の燃料タンク21のシール構造は、第1実施形態の構造において、燃料タンク21の開口部21k近くに形成される円筒部21dを、被ロック部21aとシール部21bとの間に補強部品24を挟持した二重の形状に構成したものである。
その他の構成は、第1実施形態の構成と同様であるので、第1実施形態の構成要素に20番台の符号を付して示し、詳細な説明は省略する。
燃料タンク21の開口部21kは、第1実施形態の図4と同様に、ポンプモジュール23の複数のロック部23rのツメ部23r1が燃料タンク21の被ロック部21aに係合してロックされ、ポンプモジュール23により閉塞される。
次に、燃料タンク21の補強部品24が挟持された円筒部21dの形成方法について説明する。
以下、詳述するように、燃料タンク21の全体を成形するブロー成形に際し、円筒部21dを補強部品24が挟持された二重の形状に成形する。
まず、図7(a)に示すように、燃料タンク21(図5参照)をブロー成形するに際して、燃料タンク21の円筒部21dを形成するためのキャビティc21、c22をそれぞれ有する第1の金型K21と第2の金型K22とを配置する。
続いて、図7(c)の矢印α5に示すように、円筒部21dに形成される被ロック部21aとシール部21bとの間に補強部品24を押し入れた後、パリソン21pを冷却して固化する。
続いて、補強部品24が内部に配置されたパリソン内に高圧のエアーを入れてパリソンを閉じた金型の内面に密着させて冷却して固化し、二重の形状の円筒部21dの内部に補強部品24が配置された燃料タンク21が完成する(TI-Automotive社の成形法)。
また、燃料タンク21のシール部21bの圧縮荷重によるヘタリ、変形を補強部品24による円筒部21dの強度の向上で抑制することができる。
従って、燃料タンク21のシール構造の品質が安定化し、かつ、燃料タンク21へのポンプモジュール23の組付け性が向上する車両が実現できる。
また、前記実施形態では、燃料タンク1、21を樹脂でブロー成形する場合を例示して説明したが、ブロー成形以外の方法を用いて燃料タンクを形成してもよい。
また、前記実施形態では、燃料タンク1、21の蓋体のポンプモジュール3、23が樹脂で形成される場合を説明したが、説明した機能が果たせれば、蓋体の一部等を金属、ゴム系材料等で形成してもよく、蓋体の材料は、樹脂以外の材料を用いてもよい。
