Abstract
Description
後部座席のシートクッション(例えば、後述の実施形態におけるシートクッション6)より上方に配置された吸気口(例えば、後述の実施形態における吸気口32)を有し、前記高圧電装部品と接続されて、車室(例えば、後述の実施形態における車室9)内の空気を冷却風として前記高圧電装部品に供給する吸気ダクト(例えば、後述の実施形態における吸気ダクト26)と、
前記吸気ダクトに前記冷却風を流通させる冷却ファン(例えば、後述の実施形態における冷却ファン30)と、
を備え、
前記吸気ダクトに前記車室内の空気を取り込むための開口部(例えば、後述の実施形態における開口部35)が、前記後部座席のメインシートバック(例えば、後述の実施形態におけるメインシートバック5)の幅方向外側に配設されたサイドシートバック(例えば、後述の実施形態におけるサイドシートバック4)内に形成されることを特徴とする。
前記開口部は、前記サイドシートバックの幅方向中間位置より外側に配置されることを特徴とする。
前記開口部は、その下端部(例えば、後述の実施形態における下端部35a)がドアライニング(例えば、後述の実施形態におけるドアライニング40)に設けられたアームレスト(例えば、後述の実施形態におけるアームレスト41)より30mm以上上方に位置することを特徴とする。
前記開口部は、前方視において、その少なくとも一部が前記アームレストによって隠れるように配置されていることを特徴とする。
前記開口部は、通気性を有する前記サイドシートバックの表皮(例えば、後述の実施形態における表皮34)によって覆われることを特徴とする。
前記開口部は、多数の吸気孔(例えば、後述の実施形態における吸気孔39)が形成された吸気グリル(例えば、後述の実施形態における吸気グリル37)で覆われていることを特徴とする。
前記サイドシートバックは、内部にクッション材(例えば、後述の実施形態におけるクッション材52)を有し、前記開口部から取り込まれる前記空気の吸気音が前記クッション材によって吸音されることを特徴とする。
前記開口部と、前記吸気ダクトの吸気口との間には空隙部(例えば、後述の実施形態における空隙部53)が設けられることを特徴とする。
図1に示すように、本実施形態の車両1は、エンジンとモータジェネレータとを直列に設けたパワーユニット2を備え、エンジンをモータジェネレータにより駆動補助すると共に、車両減速時等にモータジェネレータからの電力を回収可能なハイブリッド自動車である。モータジェネレータは例えば三相交流モータであり、エンジン及びモータジェネレータの駆動力は、駆動輪である前輪3に伝達される。
図8(a)及び8(b)は、本発明の第2実施形態に係る車両用高圧電装部品の冷却構造を示す。本実施形態の吸気グリル37は、図8に示すように、サイドシートバック4の裏面側から取り付けられる。即ち、サイドシートバック4の内側には、発泡ウレタン樹脂等のクッション材52が充填されており、このクッション材52内に配置されたワイヤ50にブラケット51が固定されている。このブラケット51は、開口部35が形成されており、開口部35の周縁部には複数の取付け孔36が形成されている。吸気グリル37は、少なくともブラケット51の後方に設けられたクッション材52の貫通孔52aによって、サイドシートバック4の裏面側から取付け脚38をブラケット51の取付け孔36に挿入し、係止部38aを係合することでブラケット51に固定される。
図9は、本発明の第3実施形態に係る車両用高圧電装部品の冷却構造を示す。本実施形態では、サイドシートバック4は吸気グリルを備えておらず、開口部35を含むサイドシートバック4の全面が、布等の通気性を有する表皮34で一様に覆われている。これにより、サイドシートバック4全体が同一の表皮34で覆われた一体感のあるサイドシートバック4とすることができ、商品性能が向上する。また、通気性を有する表皮34によって吸気音を低減させることができ、静粛な車室が得られる。
なお、開口部35は、乗員45が表皮34を介して接触した際に表皮34が大きく凹まないように格子状に形成されていることが好ましく、表皮34の内側に吸気グリル37が取り付けられてもよい。
図10は、本発明の第4実施形態に係る車両用高圧電装部品の冷却構造を示す。本実施形態の開口部35(吸気グリル37)は、図10に示すように、前方視において、その少なくとも一部がドアライニング40に設けられたアームレスト41によって隠れるように配置されている。これにより、開口部35からゴミ等の異物の入り込みを防止することができると共に、開口部35をアームレスト41によって隠して目立たなくすることができ、室内デザイン性が向上する。また、乗員45によって開口部35が塞がれる虞がなく、十分な吸気量を確保して効果的に冷却することができる。
