Description
通常、このエアボックス内に取り込んだ外気を、カウルトップカバーに開口された通気孔を通じて車室内に流入させることにより、車室内を換気するが、このとき、エンジンルームの熱気や臭気が車室内へ流入するという不具合がある。
例えば、車体パネル、フェンダパネルおよびフェンダプロテクタにより形成される空間部内の空気の流通を遮断するために、車体パネルにインシュレータを取り付ける場合において、インシュレータの取り付け手段に、フェンダパネルに加わる衝撃力により破断する破断部を設ける、インシュレータの取り付け構造が提案されている(例えば、下記特許文献1参照。)。
一方、上記の構造では、破断部は、取り付け手段の特定部位に設けられているところ、衝突時の衝撃が、その特定部位に十分に加わらないと、破断部が破断しない場合がある。そのような場合には、インシュレータがフェンダパネルから脱離しないため、フェンダパネルが変形しにくくなり、衝撃を吸収しにくいという不具合がある。
そこで、本発明の目的は、外力が加わる部位に関わらず屈曲して、衝撃を確実に吸収することができ、しかも、形状に関わらず生産効率を向上させることができる遮蔽板、および、その遮蔽板を備える車両構造を提供することにある。
この遮蔽板では、外力が加わることによって屈曲する応力集中部が、平板状部材の全面にわたって形成されている。そのため、外力がどの部位に加わっても応力集中部において、平板状部材を屈曲させることができる。しかも、応力集中部が平板状部材の全面にわたって設けられているので、平板状部材をどのような形状に形成しても、外力を応力集中部に作用させることができる。
また、本発明の遮蔽板では、前記平板状部材は、第1平板、第1平板と対向配置される第2平板、および、第1平板と第2平板との間に架設される複数の柱部を備え、前記応力集中部は、前記柱部の間に形成される脆弱部であることが好適である。

また、本発明の遮蔽板では、前記平板状部材には、少なくとも一方向に沿って、前記脆弱部が形成されることが好適である。

その結果、この遮蔽板は、衝突時の衝撃を、より一層確実に吸収することができる。
また、本発明の遮蔽板では、前記脆弱部が並設される方向における垂直圧縮強さが、前記脆弱部が形成される方向における垂直圧縮強さの0.02~0.9倍であることが好適である。
また、本発明の遮蔽板では、前記平板状部材に部分的に形成される補強部をさらに備えることが好適である。

また、本発明の遮蔽板では、前記平板状部材の周縁部の少なくとも一部に弾性部材が設けられていることが好適である。
その結果、この遮蔽板を、簡易な構成で、構造部材に密着させて、遮蔽効果を高めることができる。
この遮蔽板では、弾性部材が、周縁部を挟むように周縁部と嵌合する嵌合部と、嵌合部に対して平板状部材の反対側に配置される弾性部とを備えている。

そして、弾性部材3は、嵌合部9に弾性部10を接着剤などにより接着することにより形成される。
挟持部11は、平面視略矩形状の底部13と、底部の左右方向両端縁から上方に向かって延びる2枚の挟持片14とを一体的に備えている。底部13の左右方向長さは、例えば、2~18mm、好ましくは、4~12mmである。また、底部13の厚みは、例えば、0.5~5mm、好ましくは、1~3mmであり、挟持片14の厚みは、例えば、0.5~3mm、好ましくは、1~2mmである。
そして、遮蔽板1を製造するには、まず、所定形状に形成された平板状部材2の周縁部を挟むように、弾性部材3の嵌合部9を折り曲げて貼着し、次いで、クリップ4の挟持片14で平板状部材2および弾性部材3を、底部13に弾性部材3が当接するまで挟み込む。これによって、遮蔽板1を得る。
以下、図1に示される遮蔽板1の使用方法について、車両構造の一例としての車両21のカウル部24に適用する例を挙げて説明する。
図3は、図1に示される遮蔽板を備えた車両構造の一例としての車両のカウル部を左上方から見た要部斜視図である。図4は、図3に示される車両の要部左側面図である。なお、図3では、便宜的に、カウル部24の内部を直接表示しており、また、遮蔽板1の弾性部材3を省略している。
カウル部24は、車両21の左右方向に沿って配置されており、下方に向かって凹む構造のカウルフレーム25を備えている。カウルフレーム25は、前側に形成されるエンジンルーム側溝部25a、および、エンジンルーム側溝部25aの後側に連通し、より深く形成される車室側溝部25bを一体的に備えており、エンジンルーム側溝部25aと車室側溝部25bとにより、構造部材の空間の一例としてのカウル空間26が区画されている。また、車室側溝部25bの後壁には、外気を車室内に導入するための外気導入口27が形成されている。また、エンジンルーム側溝部25aおよび車室側溝部25bの底壁には、図4に示すように、遮蔽板1の前側および後側に配置されているクリップ4にそれぞれ対応する位置において、固定部挿通穴28が形成されている。
遮蔽板1をカウル空間26に配置するには、図4に示すように、前側のクリップ4の固定部12を、エンジンルーム側溝部25aの固定部挿通穴28に、後側のクリップ4の固定部12を、エンジンルーム側溝部25bの固定部挿通穴28に、底部13の下端面がカウルフレーム25の底面に当接するまで上方から挿通し、弾性部材3がカウルフレーム25の内周面に密着するように、固定する。
以下、車両21に外力としての衝撃力Iが加わった場合における遮蔽板1の作用について、図5および図6を参照しながら説明する。なお、衝撃力Iが加わる方向(図1において矢印で示す方向)は、例えば、車両21が正面衝突し、衝突した対象物が、車両21のエンジンフード23およびカウル部24の上に載りかかってきた場合などを想定している。
遮蔽板1は、図5に示すように、車両21に衝撃力Iが加わることにより、屈曲する。
詳しくは、まず、脆弱部形成方向Fとほぼ直交する方向、すなわち、前方斜め上方から、衝撃力Iが加わる(図1参照。)。
平板状部材2には、全面にわたって脆弱部8が形成されているので、図6に示すように、特に応力が集中する脆弱部8において、左側板5および右側板6のいずれかが左右方向に屈曲することにより、平板状部材2が屈曲する。
これにより、衝撃力Iが加わることにより、衝撃力Iに応じた脆弱部8において平板状部材2が屈曲し、衝撃力Iを吸収することができる。
また、この遮蔽板1によれば、平板状部材2が、左側板5、右側板6および柱部7から形成されており、柱部7の間に脆弱部8が形成されているので、柱部7において、遮蔽板1の強度を保つことができるとともに、柱部7の間の脆弱部8において、平板状部材2を確実に屈曲させることができる。
その結果、この遮蔽板1は、衝撃力Iを、より確実に吸収することができる。
この遮蔽板1では、複数の脆弱部8が、脆弱部形成方向Fと直交する方向に間隔を隔てて並設されている。そのため、脆弱部形成方向Fと直交する方向において、衝撃力Iが加わる部位に関わらず、平板状部材2を屈曲させることができる。
この遮蔽板1では、脆弱部8が並設される方向における垂直圧縮強さが、脆弱部形成方向Fにおける垂直圧縮強さの0.02~0.9倍である。すなわち、脆弱部8が並設される方向における垂直圧縮強さが、脆弱部形成方向Fにおける垂直圧縮強さよりも低く設定されている。そのため、例えば、車両21が正面衝突し、衝突した対象物が、車両21のエンジンフード23およびカウル部24の上に載りかかってきた場合などに、脆弱部8が並設される方向から衝撃力Iが加わることによって、容易に、平板状部材2を屈曲させることができる。
この遮蔽板1では、弾性部材3が平板状部材2の周縁部に全周にわたって配置されている。そのため、遮蔽板1をカウル空間26に取り付けた場合、弾性部材3が、カウル空間26の形状に応じて変形し、カウルフレーム25に密着する。
この遮蔽板1では、弾性部材3が、平板状部材2の周縁部を挟むように周縁部と嵌合する嵌合部9と、嵌合部9に対して平板状部材2の反対側に配置される弾性部10とを備えている。
また、この遮蔽板1は、カウル空間26に固定可能なクリップ4が、平板状部材2に備えられている。そのため、別途、クリップ4を形成しなくても、遮蔽板1をカウル空間26に設置することができる。
そして、この車両21は、遮蔽板1を備えているので、衝突時に、衝撃力Iを確実に吸収することができる。

図7は、本発明の第2実施形態を示す左上方から見た斜視図である。なお、図7において、第1実施形態と同様の部材には、第1実施形態と同一の符号を付し、その説明を省略する。
その場合、具体的には、架橋板32には、第1突出部34が前後方向に間隔を隔てて2つ形成されている。
そして、遮蔽板31は、例えば、貫通穴33に、第1突出部34を、左側に向かって挿通し、右側の架橋板32に対して固定することにより、取り付けられる。
図8は、本発明の第3実施形態を示す左側面図である。なお、図8において、第1実施形態と同様の部材には、第1実施形態と同一の符号を付し、その説明を省略する。
そして、各柱部42の間は、柱部42が形成されている部分に比べて脆弱な脆弱部43として区画されている。
この遮蔽板41は、第1実施形態の遮蔽板1と同様の作用効果を有している。しかも、この遮蔽板41では、脆弱部43が、3つの脆弱部形成方向Fに沿って形成され、各脆弱部形成方向Fとそれぞれ直交する方向に間隔を隔てて、並設されている。そのため、あらゆる方向において、衝撃力Iが加わる部位に関わらず、平板状部材2を屈曲させることができる。
図9は、本発明の第4実施形態における弾性部材の周縁部への貼着方法を示す説明図である。なお、以降の各図において、上記した各実施形態と同様の部材には、上記と同一の符号を付し、その説明を省略する。
上記した図2の説明では、弾性部材3を、嵌合部9と弾性部10との別々の部材から形成しているが、例えば、図9(b)に示すように、弾性層44の1つの部材から形成することができる。
また、嵌合部9の内面には、公知の粘着剤からなる粘着剤層45が積層されている。
そして、この弾性部材3を平板状部材2の周縁部に貼着するには、まず、図9(a)の破線矢印で示すように、嵌合部9の先端を平板状部材2の厚み方向両側に向けて開く。続いて、図9(a)の矢印および図9(b)に示すように、嵌合部9を平板状部材2に差し込んだ後、嵌合部9の内面を、粘着剤層45を介して、平板状部材2の周縁部に貼着する。
図10は、本発明の第5実施形態における弾性部材の周縁部への貼着方法を示す説明図である。
上記した説明では、弾性部10と嵌合部9とを、それぞれ、断面略矩形状と断面略コ字形状とに形成しているが、例えば、図10(a)に示すように、弾性部材3を、断面台形状に形成することもできる。
弾性部材3を平板状部材2の周縁部に貼着するには、まず、図10(a)の矢印で示すように、弾性部材3の内面(周縁部に対向する対向面)の粘着剤層45を、平板状部材2の周縁部に接触させる。これにより、弾性部材3の内面の幅方向中央が平板状部材2の周縁部の端面に、粘着剤層45を介して接着する。
そして、弾性部材3は、上記した幅方向両端部の引っ張りによって、断面略円形状(外側に膨出する湾曲状)に形成されて、周縁部の外方に配置される弾性部10と、周縁部の両側に配置される嵌合部9とがそれぞれ形成される。
平板状部材2は、補強部としての第1凹部16、第2凹部19および充填部17と、屈曲部18とを備えている。
また、第1凹部16は、平板状部材2の前端面を、例えば、上側から熱プレスすることによって、形成することができる。
充填部17は、図11および図13に示すように、平板状部材2に部分的に形成されており、具体的には、平板状部材2の上部に配置され、平板状部材2において前後方向にわたって形成されている。充填部17は、互いに対向する1対の柱部7、それらを架設する左側板5および右側板6によって区画される空間(充填空間)に充填材が充填されることによって、形成されている。充填部17を形成する充填材としては、例えば、平板状部材2を形成する上記した合成樹脂、および/または、上記した合成ゴム発泡体と同様のものが挙げられる。
屈曲部18は、図11および図14(a)に示すように、平板状部材2に部分的に形成されており、具体的には、平板状部材2の後端部に設けられ、脆弱部形成方向Fに対して傾斜状に延びて形成されている。すなわち、屈曲部18は、後端面から下端面にわたって、側面視直線状に形成され、前方に向かうに従って下側に傾斜状に形成されている。また、屈曲部18は、平板状部材2の左側部(図14の破線で示す左側板5および柱部7)が右方(厚み方向途中)に向かって圧縮されるように形成されている。具体的には、屈曲部18は、断面視略三角形状に凹むように形成されている。
また、屈曲部18は、平板状部材2の左側を、例えば、左側からプレスすることによって、形成することができる。
なお、この屈曲部18は、上記した衝撃力Iが加わることによって屈曲する脆弱部8とは異なり、後述する作業者による外力(応力)が加わることにより屈曲する部分として形成されている。
そのため、かかる部位の強度を高めることができる。
その結果、平板状部材2を、所定形状を保持しつつ、屈曲させて衝撃力Iを吸収することができる。
そのため、かかる部位の強度を高めることができる。
その結果、平板状部材2を、所定形状を保持しつつ、屈曲させて衝撃力Iを吸収することができる。
詳しくは、遮蔽板1を配置する箇所の手前に狭小空間がある場合、屈曲部18を屈曲させることにより、平板状部材2を折り畳んだ状態で、その狭小空間を通過させた後、再度屈曲部18を伸展させることにより、平板状部材2を開いた状態で配置する。
好ましくは、図11の実線で示すように、屈曲部18を、脆弱部形成方向Fに対して傾斜状に形成する。
上記した説明では、屈曲部18を、断面視三角形状に切り欠かれるように形成しているが、その形状は特に限定されず、例えば、図16~図19に示すように、断面視略矩形状(図16、図18および図19)、断面視略W字形状(図17)に、凹むように形成することもできる。
屈曲部18は、上下方向に沿って形成され、上下方向に沿って屈曲可能に形成されている。
これにより、屈曲部18の柔軟な屈曲を達成することができる。
そのため、カウル部24のカウル空間26(図3参照)に液体(具体的には、雨水および/または洗浄液など)および/またはそれとともに流れる固体状の異物の流れが生じたときに、それに起因する押圧力によって、平板状部材2を屈曲させることができ、車両21のカウル部24内におけるカウル空間26(図3参照)に流れる液体および/または異物を通過させることができる。
この屈曲部18は、2つの圧縮部分50によって、より一層柔軟な屈曲を達成することができる。そのため、上記した車両21のカウル部24内におけるカウル空間26(図3参照)に流れる液体および/または異物をより一層確実に通過させることができる。
また、左筋目51および右筋目52は、左右方向(厚み方向)に投影したときに、互いに直交しており、より具体的には、左筋目51が、上方に向かうに従って後方に傾斜する一方、右筋目52が、上方に向かうに従って前方に傾斜している。
そして、この遮蔽板1では、筋目30によって、屈曲部18の屈曲性を高めることができる。そのため、上記した車両21のカウル部24内におけるカウル空間26(図3参照)に流れる液体および/または異物を確実に通過させることができる。
なお、図18の説明では、屈曲部18は、平板状部材2の上下方向全体にわたって形成されているが、例えば、上下方向端部または方向途中に形成することもできる。
図19において、平板状部材2には、それを2つに分断するスリット35が形成されており、スリット35の両側の平板状部材2の左側面に架設される第1可撓性シート36によって、屈曲部18が形成されている。
この屈曲部18では、第1可撓性シート36によって、屈曲部18の柔軟な屈曲を達成することができ、車両21のカウル部24内におけるカウル空間26(図3参照)に流れる液体および/または異物を通過させることができる。
図20において、この遮蔽板1は、可撓性シートとしての第2可撓性シート37をさらに備えている。
すなわち、第2可撓性シート37は、平板状部材2の第2突出部53の周縁部から外方(前方、後方および下方)に延出する延出部38を備えている。
第2可撓性シート37は、例えば、上記した第1可撓性シート36を形成する材料と同様の材料から形成され、好ましくは、上記した合成ゴムから形成されている。
撓み部39は、図21の矢印で示すように、延出部38の延出方向途中を左側に向けて撓ませながら、延出部38の先端部を、平板状部材2の周縁部の左側面に、図示しない接着剤を介して接着することにより形成される。
また、蛇腹部40は、図20に示すように、前端部から前方に延出しており、断面蛇腹状に形成されている。また、蛇腹部40には、前後方向に沿って延びる折り目54が、上下方向に間隔を隔てて形成されている。
重なり部分46は、平板状部材2の周縁部の外側(上側)に配置され、弾性層44が粘着剤層45を介して互いに接着されることにより互いに重なる部分として区画されている。
そして、この弾性部材3を平板状部材2の周縁部に貼着するには、まず、図23(a)に示すように、弾性層44、その表面に形成される粘着剤層45およびその表面に形成される離型フィルム57を備える弾性粘着シート55を用意する。
次いで、図23(b)に示すように、幅方向中央の離型フィルム57を、切り目58に沿って、粘着剤層45から引き剥がす。
次いで、図23(c)に示すように、幅方向中央の弾性層44を、それらが互いに重なるように、粘着剤層45を介して接着する。これにより、重なり部分46と、それから連続し、2方向に延びる貼着部分47とが形成される。
この遮蔽板1では、可撓性の延出部38を、遮蔽板1が取り付けられるカウル部24(図3参照)に対して確実に装着することができる。
また、この遮蔽板1では、貼着部分47によって、重なり部分46を平板状部材2に固定することができるとともに、重なり部分46が、カウル部24に対して、確実に密着することができる。
さらに、弾性部材3の平板状部材2の周縁部の端面に対する配置(図23(d)参照)では、重なり部分46と貼着部分47との連続部を、周縁部の端面の中心に対向配置させることにより、貼着部分47を、周縁部の右側面および左側面にバランスよく、かつ、簡単に配置して、貼着することができる。
