【発明の属する技術分野】
本発明は、インタークーラーを冷却する外気をフロントグリルから取り込む構造を有するインタークーラー付自動車のグリル部構造に関する。
【０００２】
【従来の技術】
図１２は、従来のインタークーラー付自動車のグリル部構造を示す。車体の前面下部に設けたフロントバンパー５０の上側には、外気を取り込む吸気口の機能を備えたフロントグリル５１が取り付けられ、このフロントグリル５１の裏側には、取り込んだ外気を図示しないインタークーラーに導くエアダクト５４が配設されている（例えば、特許文献１参照。）。また、このエアダクト５４の設置スペースは狭く限られているので、このエアダクト５４の形状等を工夫して、外気を取り込むために開口部５５を大きくとる技術がある（例えば、特許文献２参照）。
【０００３】
また、フロントグリル５１の裏側であってエアダクト５４の前側には、フロントグリル５１のフィン５２のすき間からエンジンルームが見えないようにするためのグリルカバー５３が配設される場合がある。このグリルカバー５３には、グリルカバー５３とエアダクト５４の開口部５５とが対向する場合、この部分に外気を通すための穴を穿設しなければならない。

【０００５】
【発明が解決しようとする課題】
しかしながら、フロントグリル５１の裏側にエアダクト５４を配設する場合、狭い設置スペースの中で開口部５５を大きく設けるには限界がある。また、グリルカバー５３は、エンジンルーム内部への視界を遮るためのもので、通常、外気を取り込むための機能は設けられていない。
【０００６】
また、図１３に示すように、フロントバンパー５０の別の箇所にエアダクト５４を取り付ける技術もあるが（例えば、特許文献３参照。）、部品点数が増えることや、フロントバンパー５０に穴を設けるために、走行中の異物や泥水が浸入することへの影響が懸念される。
【０００７】
本発明はこのような実情に鑑みてなされたものであって、その目的は、外気の取り込み性能がより向上するとともに、フロントグリルの前側からエンジンルーム内部への視界を遮ることのできるインタークーラー付自動車のグリル部構造を提供することにある。
【０００８】
【課題を解決するための手段】
本発明は、車体前面に吸気口として外気を取り込むフロントグリルを設け、該フロントグリルの後部側に外気をインタークーラーへ導くエアダクトを配設したインタークーラー付自動車のグリル部構造において、前記エアダクトの前部に、走行中の外気を集める導風カバー部を一体に設けて導風カバー付エアダクトを構成し、該導風カバー付エアダクトの該導風カバー部を前記フロントグリルのすき間からエンジンルーム内部への視界を遮るように配設した。
また、前記導風カバー付エアダクトは、前記導風カバー部と外気を導くエアダクト部から構成され、そのエアダクト部の前側開口の開口面積が、外気を排出する後側開口の開口面積よりも広くしている。
本発明は、前記導風カバー付エアダクトの導風カバー部の内面を外周面よりも一段後方にへこませている。
【０００９】
本発明は、前記エアダクト部の後側開口面を前側開口面よりも上方向に設けるために、前記導風カバー付エアダクトの成形金型を、固定金型と、水平方向に移動する水平金型と、鉛直方向に移動する鉛直金型から構成し、前記エアダクト部の内側面が固定金型と水平金型で成形され、前記エアダクト部の外側面の上側部が鉛直金型で成形されるようにしている。
さらに、前記導風カバー付エアダクトの導風カバー部における上部側裏面には、車体後方に突出する係合爪が設けられ、該係合爪を前記鉛直金型を用いて成形するとともに、前記係合爪の先端部に係合用突起を車幅方向に向けて設けることもできる。
【００１０】
本発明は、前記エアダクト部の後側開口面を前側開口面よりも下方向に設けるために、前記導風カバー付エアダクトの成形金型を、固定金型と、水平方向に移動する水平金型と、鉛直方向に移動する鉛直金型から構成し、前記エアダクト部の内側面が固定金型と水平金型で成形され、前記エアダクト部の外側面の下側部が鉛直金型で成形されるようにしている。
さらに、前記導風カバー付エアダクトの導風カバー部における下部側裏面には、車体後方に突出する係合爪が設けられ、該係合爪を前記鉛直金型を用いて成形するとともに、前記係合爪の先端部に係合用突起を車幅方向に向けて設けることもできる。
【００１１】
さらにまた、車体前面に吸気口として外気を取り込むフロントグリルを設け、該フロントグリルの後部側に外気をインタークーラーへ導くエアダクトを配設したインタークーラー付自動車のグリル部構造において、前記フロントグリルと前記エアダクトを一体に成形してエアダクト付フロントグリルを構成することもできる。
【００１２】
【発明の実施の形態】
以下に、本発明の実施の形態に係るインタークーラー付自動車のグリル部構造について、図面を用いて説明する。
なお、本明細書で記載する方向は、特に指定していない場合、車体の前方向を向いて取り付けられる面を表面または表側と、その逆側の面を裏面または裏側とする。
【００１３】
図１は本発明のグリル部構造を設けた自動車１を斜め前方から見た斜視図を、図２は図１の分解斜視図を、図３はフロントグリル部の構成を示す分解斜視図を示す。
【００１４】
自動車１の前面部は、前面下部を構成するフロントバンパー２と、フロントバンパー２の上側に設けられ前面部の意匠を構成するとともに、吸気口として外気をエンジンルーム３の中に取り込むためのフロントグリル４が設けられている。エンジンルーム３の内部には、図示しないエンジンに、過給された吸気を冷却するインタークーラー５が設けられており、このインタークーラー５にはインタークーラー５を冷却するための外気を導くエンジン側エアダクト６が配設されている。
【００１５】
フロントグリル４の後部側とエンジン側エアダクト６との間には、本発明の実施の形態に係る導風カバー付エアダクト７が設けられている（図３参照）。この導風カバー付エアダクト７は、外気を案内すると共にエンジンルーム３の視界を遮る導風カバー部８と、インタークーラー５に外気を送るエアダクト部９とで一体に構成している。
【００１６】
導風カバー部８の表面は、例えば、正面から見て四角形状に形成され、この実施の形態では、フロントグリル４の表面積に対して略半分の大きさで構成されている（図３参照）。導風カバー付エアダクト７の配置は、車体正面側から見て、フロントグリル４の左側部分の裏側に配設される。この導風カバー付エアダクト７の形状、大きさ、および配置は、車の構造やフロントグリル４の部品配置等により他部品と干渉しないように適宜決定することができる。
【００１７】
図４に本発明の形態に係る導風カバー付エアダクト７の正面図を、図５には図４のＡ−Ａ線による断面図であって、車体前側部分に導風カバー付エアダクト７が組み込まれた状態を示す。図６には図４のＢ−Ｂ線による断面図であって、車体前側部分に導風カバー付エアダクト７が組み込まれた状態を示す。
【００１８】
導風カバー部８には、四角形の外縁部に略同一平面で構成する外周面１０と、その外周面１０によって囲まれた内面は、外周面１０に対し車体後方側にへこんだ段差面１１として構成されている。外周面１０と段差面１１により生じる内周面１１ａには、外気が段差面１１に当たって段差面１１の外側方向に拡散して逃げるのを防止する機能がある。また、段差面１１には、ターボユニット冷却用穴２６とホーンの音をさえぎらないための穴２７を設けている。
【００１９】
外周面１０の裏面の上側および下側部分には、上側係合爪１６ａ、および下側係合爪１６ｂが設けられている。この係合爪１６ａ、１６ｂは、外周面１０の裏側の方向へ突出しており、その先端部には係合用突起１７が上下または左右方向に突出して鉤形形状を形成する。この係合用突起１７がフロントバンパー２に設けた係合穴１５ａ、１５ｂ（図３参照）に挿通された後に、係合穴１５ａ、１５ｂの縁部と係合して、導風カバー付エアダクト７が固定される。
なお、係合爪１６は、外周面１０の上側および下側に限らず、構造に合わせて左右側に設けることもできる。
【００２０】
エアダクト部９は、例えば、段差面１１の面に穿設した略四角形状の前側開口１２と、外気を導くダクト１３と、ダクト１３の終端部にあってエンジン側エアダクト６に連結する後側開口１４とが設けられている。この前側開口１２の開口面積は、より多くの外気を取り込むことができるように、後側開口１４の開口面積よりも大きくなるように設けてある。
【００２１】
後側開口１４は、前側開口１２に比べ上方にオフセットして配置してある。このオフセット量は、例えば、エンジン側エアダクト６の開口部の前面に配置するのに適した位置や、導風カバー付エアダクト７の背面に設けた部品との干渉をさけるのに適した位置等に自由に決定することができる。
【００２２】
導風カバー付エアダクト７の形状は、図４から図６に示すように、前側開口１２の右側、上側、および下側側面部分から後側開口１４に向けて傾斜面１４ａを設けている。この傾斜面１４ａは、外気を乱すことなく導くために設けられる。
なお、本実施例では、前側開口１２の正面左側部分は、本図の構成では導風カバー付エアダクト７の構成上の制約により傾斜面１４ａを設けていないが、導風カバー付エアダクト７の設置スペースや部品配置に合わせて適宜設けることができる。
【００２３】
次に、本発明に係る導風カバー付エアダクト７を成形する金型について説明する。図７は、導風カバー付エアダクト７を成形する金型構造の断面図を示す。図８は、図７の上側部分の拡大断面図を示し、図９は、図８のＵ方向の矢視拡大図を示す。
【００２４】
上述のように、後側開口１４が前側開口１２に対して上方にオフセットした形状を成形するために、導風カバー付エアダクト７の成形金型は、移動しない固定金型（コア型）１８と、水平方向１９に移動する水平金型（キャビ型）２０と、鉛直方向２１に移動する鉛直金型（スライド型）２２の３分割で構成される。
固定金型１８は、エアダクト部９の内側面上側部２３ａと、外側面下側部２３ｂと、導風カバー部８の下側面２４と、下側係合爪１６ｂを成形する。水平金型２０は、エアダクト部９の内側面下側部２３ｃと、導風カバー部８の外周面１０と、段差面１１を成形する。また、鉛直金型２２は、エアダクト部９の外側面上側部２３ｄと、導風カバー部８の上側係合爪１６ａを成形する。
【００２５】
外周面１０の下側に設けた下側係合爪１６ｂは、固定金型１８と水平金型２０を用いて係合用突起１７を下側に向けて成形することができる（図７参照）。一方、上側係合爪１６ａの係合用突起１７は、後側開口１４を上方にオフセットしたために、固定金型１８と水平金型２０を用いて係合用突起１７を上側または下側に向けて構成することができない。そのため、鉛直金型２２を用いて上側係合爪１６ａの係合用突起１７を水平方向に向けて成形する（図８、および図９参照）。
【００２６】
本発明では、導風カバー付エアダクト７の前部に導風カバー部８を一体に設けることにより、より多くの外気をエアダクト部９に導くことができるとともに、エンジンルーム内が直接見えないようにすることができる。これにより、グリルカバーの取り付け部品等の部品点数を削減することができる。
また、エアダクト部９の前側開口１２の面積を後側開口１４の面積よりも大きくしたこと、および外周面１０より後側に窪んだ段差面１１を設けたことにより、より多くの外気をインタークーラー５に取り込むことができる。
また、導風カバー付エアダクト７の成形金型を、固定金型１８、水平金型２０、鉛直金型２２で成形することにより、前側開口１２に対して後側開口１４をオフセットした位置に成形でき、部品レイアウトやデザインの自由度が増える。また、係合爪１６ａ、１６ｂを取付必要箇所に一体成形することができるので、導風カバー付エアダクト７をフロントバンパー２に強固に固定することができる。
【００２７】
なお、本発明は、図１０に示すように、後側開口１４を前側開口１２に対して下側に設けることもできる。成形金型は、後側開口部を上側に設ける場合と同様に固定金型１８、水平金型２０、鉛直金型２２の３分割で構成し、鉛直金型２２を下側に配置するとともに、下方へ移動する構造とする。この場合、固定金型１８は、エアダクト部９の内側面下側部２３ｃと、外側面上側部２３ｄと、導風カバー部８の上側面２４を成形する。水平金型２０は、エアダクト部９の内側面上側部２３ａと、導風カバー部８の外周面１０と、段差面１１を成形する。また、鉛直金型２２は、エアダクト部９の外側面下側部２３ｂを成形する。下側係合爪１６ｂは、上記と同様に、鉛直金型２２を用いて係合用突起１７を水平に向けて成形する。
【００２８】
また、本発明は、図１１に示すように、本案の手法を用いて、フロントグリル４とエアダクト２５を一体成形することもできる。
【００２９】
さらに、本実施例では、この一体に構成する方法として樹脂成形によるものを説明したが、鋼板を用いて別体で製作したものを溶接やボルト類で接続して一体に構成する方法なども本発明の技術的範囲に含まれる。この場合には、取り込んだ外気が継ぎ目部から逃げないように構成するのが好ましい。
【００３０】
【発明の効果】
本発明に係るインタークーラー付自動車のグリル部構造によれば、次のような効果を奏することができる。
車体前面に吸気口として外気を取り込むフロントグリルを設け、該フロントグリルの後部側に外気をインタークーラーへ導くエアダクトを配設したインタークーラー付自動車のグリル部構造において、前記エアダクトの前部に、走行中の外気を集める導風カバー部を一体に設けて導風カバー付エアダクトを構成し、該導風カバー付エアダクトの該導風カバー部を前記フロントグリルのすき間からエンジンルーム内部への視界を遮るように配設しているので、より多くの外気を取り込むことができる。また、従来のグリルカバーと、その取り付け部品が削減できるとともに、組立工数の低減を図ることができる。
前記導風カバー付エアダクトは、前記導風カバー部と外気を導くエアダクト部から構成され、そのエアダクト部の前側開口の開口面積が、外気を排出する後側開口の開口面積よりも広くしているので、より多くの外気をインタークーラーに取り込むことができる。
前記導風カバー付エアダクトの導風カバー部の内面を外周面よりも一段後方にへこませているので、前側開口面よりも大きな段差面で外気を集めるとともに、自動車が走行中に取り込む外気を導風カバー部の外側に逃がすことなく、より多くの外気を効率よくインタークーラーに導くことができる。
【００３１】
前記エアダクト部の後側開口を前側開口よりも上方向に設けるために、前記導風カバー付エアダクトの成形金型を、固定金型と、水平方向に移動する水平金型と、鉛直方向に移動する鉛直金型から構成し、前記エアダクト部の内側面が固定金型と水平金型で成形され、前記エアダクト部の外側面の上側部が鉛直金型で成形されるので、後側開口面の上下位置を前側開口面よりも上方向にオフセットして成形することができるため、部品レイアウトやデザインの自由度が広がる。
前記導風カバー付エアダクトの導風カバー部における上部側裏面には、車体後方に突出する係合爪が設けられ、該係合爪を前記鉛直金型を用いて成形するとともに、前記係合爪の先端部に係合用突起を車幅方向に向けて設けているので、取り付けボルト等の数を減らすことができる。また、取付必要箇所に係合爪を設けているので、エアダクトを強固に周辺部品に固定することができる。
【００３２】
前記エアダクト部の後側開口面を前側開口面よりも下方向に設けるために、前記導風カバー付エアダクトの成形金型を、固定金型と、水平方向に移動する水平金型と、鉛直方向に移動する鉛直金型から構成し、前記エアダクト部の内側面が固定金型と水平金型で成形され、前記エアダクト部の外側面の下側部が鉛直金型で成形されるので、後側開口面の上下位置を前側開口面に対して下方にオフセットして成形することができるため、部品レイアウトやデザインの自由度が広がる。
前記導風カバー付エアダクトの導風カバー部における下部側裏面には、車体後方に突出する係合爪が設けられ、該係合爪を前記鉛直金型を用いて成形するとともに、前記係合爪の先端部に係合用突起を車幅方向に向けて設けているので、取り付けボルト等の数を減らすことができる。また、取付必要箇所に係合爪を設けているので、エアダクトを強固に周辺部品に固定することができる。
