Description
本願は、2014年10月16日に、日本に出願された特願2014-211778号、2014年10月16日に、日本に出願された特願2014-211779号、及び2014年10月16日に、日本に出願された特願2014-211780号に基づき優先権を主張し、その内容をここに援用する。
しかしながら、ミラーベースがハウジングの上下方向の中間付近で係合される構成のサイドミラー装置では、ハウジング内部におけるミラーベースの上側に十分なスペースを確保することが難しい。このため、ミラーベースの上側に軸受機構と可倒機構とを形成することが困難であり、レイアウト上の制約が大きいという課題があった。
(1)本発明の第一の態様に係るサイドミラー装置は、車両の側面から外方に向けて延設されるミラーベースと、前記ミラーベースに対して回動可能に取り付けられたハウジングと、前記ハウジングと前記ミラーベースとを回動可能に係合させる軸受機構と、前記ハウジングに収容されるミラーと、前記ミラーが前記車両の進行方向後側に向けられた使用位置において、前記ハウジングに予め設定された値を超える応力が印加された際に、前記ミラーが前記車両の側面に対向する収納位置に向けて前記ハウジングを回動させる可倒機構と、を備え、前記軸受機構および前記可倒機構は、前記ハウジングの内部に収容され、前記軸受機構と前記可倒機構とは、前記軸受機構の軸線に沿って、前記ミラーベースを挟んで互いに対向するように形成されている。
また、ミラーベースの係合領域を上カバーおよび下カバーに対して直接対面させることでミラーとハウジングとの一体感を向上させ、優れたデザイン性を持つサイドミラー装置を実現することができる。
これにより、より一層確実にハウジングの上下で流速の差異が生じることを防止でき、ハウジングの後部での乱流の発生を抑制して、空力抵抗や走行中の不快な風切り音を低減することができる。
なお、以下の説明においては、車両の進行方向(前後方向)前側を単に前側、進行方向後側を単に後側、前側及び後側に沿った方向を進行方向、上下方向(重力方向)上側を単に上側、上下方向下側を単に下側、上側及び下側に沿った方向を上下方向、進行方向および上下方向に対して直角な車体の幅方向を単に車幅方向と称して説明する。また、参照する各図面においては、進行方向をL、上下方向をH、車幅方向をWとして矢印で示す。
本実施形態のサイドミラー構造を備えた車両1は、例えば、車体2を構成するフロントピラー3とリアピラー4との間のルーフ部分が開閉可能な2ドアのオープンカー(コンパーチブル、カブリオレ)である。車体2の進行方向Lに沿った両側面には、それぞれドア10,10が開閉可能に取り付けられている。また、フロントピラー3には、フロントガラス5が取り付けられている。
なお、車両1の側面に設けられるサイドミラー装置20は、車両1の前側から見て右側のドア10と左側のドア10のそれぞれに形成されているが、以下の説明においては、車両1の前側から見て左側のドア10に形成された左側のサイドミラー装置20に着目して説明する。従って、右側のドア10に形成された右側のサイドミラー装置20も、左側のサイドミラー装置20と同様の構成である。
本実施形態のサイドミラー装置20は、上カバー(上部カバー)21、下カバー(下部カバー)22、および中央カバー23を備えたハウジング24と、このハウシング24の内部に配される内部ハウジング25、およびミラー26と、内部ハウジング25を介してハウジング24を回動可能に支持するミラーベース27と、を有する。内部ハウジング25は、ミラー26を保持するミラー保持凹部29を備え、ハウジング24は、内部ハウジング25を覆うカバー28を備える。
このミラー26は、内部ハウジング25に形成されたミラー可動機構35によって、反射面26aが任意の向き(角度)に調節可能なように取り付けられている。
なお、本実施形態におけるサイドミラー装置20の各方向の記載は、この使用位置における方向を基準にしている。
また、車両1の左側のサイドミラー装置20のハウジング24を構成する下カバー22は、車両1の右側のサイドミラー装置20のハウジング24を構成する上カバー21と同一形状であり、同一の部材である。
また、上カバー21の外表面21aおよび下カバー22の外表面22aは、車両1の進行方向Lに沿ってミラーベース27から後側に向けて遠ざかるほど、それぞれの外表面21a,22aの傾斜が水平方向に近づく形状に成形されている。
そして、進行方向Lの前側において、上カバー21の前端および下カバー22前端との隙間を閉塞し、上カバー21および下カバー22との間で挟まれる形状をなす。
なお、本実施形態でのサイドミラー装置20の各方向の記載は、この使用位置Q2における方向としている。
図9は、サイドミラー装置の上カバー部分における車幅方向に沿った断面図である。また、図10は、サイドミラー装置の中央カバー部分における車幅方向に沿った断面図である。
上カバー21と下カバー22のそれぞれの外周縁部には、内部ハウシング25における進行方向Lの後側の外周縁部25C、および中央カバー23における外周縁部23Cと係合可能な凹部21C,22Cが形成されている。
内部ハウシング25と中央カバー23との間には所定の隙間E3が形成され、この隙間には、上カバー21および下カバー22と、内部ハウジング25とを接続する接続部材32が形成されている。この接続部材32は、上カバー21および下カバー22の内面側にそれぞれ形成された係合孔21h,22h(図7参照)と、内部ハウシング25の上側および下側にそれぞれ形成された係合突起25p(図4参照)とからなる。
中央カバー23の車幅方向Wに沿った外側縁部には、内部ハウジング25と係合する爪部23p1が形成されている。また、中央カバー23の車幅方向Wに沿った内側縁部には、内部ハウジング25と係合する係合爪23p2が形成されている。
爪部23p1および係合爪23p2によって、中央カバー23は、車幅方向Wに沿った外側縁部と内側縁部とで、それぞれ内部ハウジング25に係合される。
ミラーベース27とハウジング24との係合部分において、ハウジング24の内部に回動装置(軸受機構)31および可倒機構36が形成されている。可倒機構36は、使用位置Q2においてハウジング24に予め設定された値を超える応力が、進行方向Lの後側に向けて印加された際に、収納位置Q1に向けてハウジング24を回動させる。これによって、サイドミラー装置20の破損を防止する。
本実施形態では、こうしたハーネス59は、ミラーベース27の水平部27bから下方向に延び、スプリングシャフト57の下側を経由してミラー可動機構35に延びている。
これにより、上カバー21および下カバー22の外表面21a,22aが中央カバー23に接する前側の傾斜角度をより一層鋭角(急角度)にすることができ、ハウシング25の外形をコンパクトにして、小型で優れたデザイン性を持つサイドミラー装置20を実現することができる。
下カバー22を形成する金型も同様の構成にすることができる。このため、金型54の構造を簡易にすることが可能になり、カバー28を低コストで容易に製造することができる。
例えば、上述した実施形態では、サイドミラー装置20を車両のドア10に設けた構成、即ちドアミラーを例示したが、サイドミラー装置20を車両のフロントフェンダに設けた構成、即ちフェンダミラーにも適用可能である。
