Description

【0001】
【発明の属する技術分野】
本発明は、筐体に収容されたモニタを使用に際して筐体から突出させることが可能な車載用ディスプレイ装置に関する。
【0002】
【従来の技術とその問題点】
筐体に収容される収容状態と筐体から突出する使用状態との間でモニタを電動駆動可能な車載用ディスプレイ装置が知られている。このようにモニタを移動可能に構成すると、車両の振動によってモニタがガタつき、不快音が発生する等の問題がある。特に使用時のモニタ位置(角度)を調節可能なものでは、モニタを中途半端な位置で停止させることがあり、このような場合は通常のガタとりスプリングでは完全にガタをとることができない。
【0003】
本発明の目的は、比較的簡単な構成で車両の振動等によるモニタのガタつきを極力防止し得る車載用ディスプレイ装置を提供することにある。
【0004】
【課題を解決するための手段】
一実施の形態を示す図1〜図17に対応づけて説明すると、本発明は、筐体20内に収容される収容状態と、筐体20から突出する突出状態との間で移動可能なモニタ10と、モニタ10に設けられた突部11aと係合する第1の係合部42aを有し、筐体20に対して移動する移動部材40と、突部11aと係合して突部11aの移動を案内する第2の係合部31を有するガイド部材30と、モニタ10に回動可能に連結される部分と、筐体に回動可能に連結される部分とを有し、モニタの姿勢を変更するための姿勢変更部材80とを備え、移動部材40の移動に伴い、第1の係合部42aと突部11aとの係合によってモニタ10が移動し、モニタ10の移動は、突部11aと係合する第2の係合部31によって案内され、モニタ10の移動に連動して、姿勢変更部材80によってモニタ10の姿勢が変更され、モニタ10の移動および姿勢変更によってモニタ10を収容状態と突出状態との間で駆動する車載用ディスプレイ装置に適用される。
そして、突部11aに係合可能とされ、モニタ停止時のガタを防止すべく突部11aが第1の係合部42aおよび第2の係合部31の双方に押圧されるように突部11aを付勢する付勢手段71,72を備え、これにより上記問題点を解決する。
請求項2の発明は、モニタ10が収容状態から所定の中間状態に達するまでは付勢手段71,72の付勢力がモニタ10に作用せず、モニタ10が中間状態に達してから以降は付勢手段71,72の付勢力がモニタ10に作用するよう構成したものである。
請求項3の発明は、突部11aと係合可能な付勢係合部材71と、この付勢係合部材71を介して突部11aを付勢するばね部材72とから付勢手段を構成し、ばね部材72の付勢力が突部を第1および第2の係合部42a,31の双方に押圧する力として作用するよう付勢係合部材71が突部11aに係合されるものである。
請求項4の発明は、モニタ10が収容状態から所定の中間状態に達するまでは、突部11aが付勢係合部材71と非係合状態を保持するようにしたものである。
請求項5の発明は、突部11aがその移動に伴って付勢係合部材71をばね部材72の付勢力に抗して移動させるとともに、付勢係合部材71に係合する突部11aが、第1および第2の係合部42a,31に対して常に略同一方向に押圧されるよう付勢係合部材71の移動を案内する案内部材34を備えたものである。
【0005】
なお、本発明の構成を説明する上記課題を解決するための手段の項では、本発明を分かり易くするために実施の形態の図を用いたが、これにより本発明が実施の形態に限定されるものではない。
【0006】
【発明の実施の形態】
−第1の実施の形態−
図1〜図17により本発明の第1の実施の形態を説明する。
本実施の形態にかかる車載用ディスプレイ装置は、テレビ放送やナビゲーションシステムの各種情報などを表示するためのもので、車両のダッシュボード1(図1)に埋設されるものである。モニタ10は、不使用時にはダッシュボード1内に完全に格納されており、使用にあたってダッシュボード1のリッド1aを開きつつ視認可能な位置まで突出する。図2はモニタ10の収容状態を示し、このときリッド1aは不図示のばねの付勢力により完全に閉じている。所定操作がなされると、モータの駆動力によりモニタ10は図2→図3→図4→図5のように突出しつつ姿勢を変え、最終的には図6に示す位置に達する。
【0007】
上述したモニタ10の動作を実現するための構成を以下に詳述する。
図7および図8はモニタ駆動機構を示し、20はモニタ10を格納する筐体、30は筐体20の両側壁の内面側にそれぞれ配置されるカム部材、40は筐体20内をA方向(車両前方)およびB方向(車両後方)に移動可能なスライドベースである。筐体20は、底板21と左右の側板22と後板23と前板24とから成り、底板21には左右にラック部材51が固着されている。ラック部材51にはA−B方向に延在するラック51aとガイド溝51bとがそれぞれ形成され、ラック51aにスライドベース40のピニオン65が噛み合うよう構成される。両側板22の内面には、後述するモニタ付勢用の引張ばね91の一端が掛止されるばね掛け22aが形成されている。
【0008】
各カム部材30の内面には、図8に示すようにカム溝31と、直進ガイド溝32と、案内溝34,35とが形成されている。カム溝31にはモニタ10のフォロアピン11aが係合され、直進ガイド溝32にはスライドベース40の不図示のガイド突起が係合される。案内溝34は、ガタ防止用の係合部材71の移動を案内するもので、係合部材71に突設された2本のピンが係合される。係合部材71の一端部は図示の如くカム溝31側に突出し、ここにフォロアピン11aが係合される。係合部材71のばね掛けとカム部材30のばね掛け34aとには引張ばね72の両端が掛止され、このばね72の付勢力により係合部材71はA方向に付勢されている。案内溝35はばね72の伸縮を案内するものである。
【0009】
スライドベース40は、底板41と左右の側板42と後板43と前板(図7,図8では不図示)とから成り、側板42には上下方向の長孔42aが形成される。なお上述した係合部材71は、この側板42とカム部材30の間に配置される。図9に示すように、スライドベース40の底板41には板状のモータブラケット61を介してモニタ駆動用のモータ62が取付けられる。モータ62の出力軸にはウォーム62aが取付けられ、モータ62の駆動力はウォーム62a,ウォームホイール63を介してクラッチ付きのギア部材64に伝達された後、不図示の減速ギア列を介してピニオン65(図7)に伝達される。ピニオン65の回転によりラック51aを介してスライドベース40がA−B方向に移動する。
【0010】
図10に示すように、モニタ10は前面に表示画面13を有するとともに、左右の側面にはブラケット11が固着され、各ブラケット11の下端にフォロアピン11aが突設されている。これらのフォロアピン11aが上述したスライドベース40の側面の長孔42aを貫通してカム部材30のカム溝31に係合される。14はモニタ10の両側面に設けられた軸支部である。
【0011】
モニタ10の内部には、図11に示すようなローラ12がベース13を介して取付けられ、ローラ12の一部がモニタ10の上面と背面との角部中央から突出している。ローラ12はブッシュ12aとその回りに配置されるゴム製の当接部12bとを有し、軸14を介してベース13に回転可能に軸支されている。ブッシュ12aの一端側とベース13との間にはガタとり用の圧縮ばね15が介装され、このばね15によりローラ12は図示右側に押圧されている。モニタ10が突出するとき、このローラ12が車両側のリッド1aに当接して回転し、リッド1aを開放する。
【0012】
図12〜図14はモニタ駆動用のリンク部材80を示している。リンク部材80は左右のリンク部81とそれらを連結する連結部82とから成り、各リンク部81にはばね掛け81aが形成されている。また、各リンク部81には2つの軸支部81b,81cが設けられ、図2や図15に示すように一方の軸支部81bはモニタ側面の各軸支部14に、他方の軸支部81cは各カム部材30に突設された軸支部33にそれぞれ回動可能に軸支される。各リンク部81のばね掛け81aと筐体側板22の各ばね掛け22aには、ガタとり用の引張コイルばね91の両端が掛止され、これによりリンク部材80は常に図2の時計回り方向に付勢される。
【0013】
以上のように構成された車載用ディスプレイ装置の動作を詳細に説明する。
図2に示す格納位置では、モニタ10は画面13が下方を向く横臥姿勢をとり、完全に筐体20内つまりダッシュボー1ド内に格納されている。このときダッシュボード1のリッド1aは不図示のばねの付勢力により閉じ、モニタ10のローラ12とはまだ非接触である。スライドベース40は図9に示す位置(モニタ10の後方)にあり、モニタ10は引張ばね91によりリンク部材80を介して格納位置を保持する方向に付勢されている。これにより車両に振動が発生してもモニタ10がガタつくことがなく、不快音の発生が防止できる。
【0014】
所定のモニタ突出操作が行われると、モータ62が正方向に回転駆動され、その回転はウォームホイール63,ギア部材64および不図示の減速ギア機構を介して左右のピニオン65に伝達され、ピニオン65とラック51aとの噛合によりスライドベース40が図7のB方向に移動を開始する。スライドベース40はラック部材51のガイド溝51bおよびカム部材30のガイド溝32によりその移動が案内される。スライドベース40の移動に伴って長孔42a(図8)の端面がモニタ10のカムフォロア11aをB方向に押圧し、フォロアピン11aは長孔42aを上方に移動しつつカム溝31内を移動する。これに連動してリンク部材80が筐体20に対して回動し、モニタ10の姿勢(角度)を代える。このスライドベース40,カム部材30およびリンク部材80の作用により、図3に示すようにモニタ10が移動しつつ起き上がる。各位置におけるモニタ10の姿勢はカム溝31の形状とリンク部材80の連結位置とで決る。
【0015】
モニタ10が起き上がるとローラ12がリッド1aの下面に当接し、リッド1a上を転動しつつこれを押し開ける。図2から図3,図4の状態を順次経て図5の状態に達するまで、モニタ10はスムーズに起き上がり、図5の状態で直立姿勢となり、このときリッド1aは最も開いた状態となる。これ以降はモニタ10が逆方向に倒れるが、その際、図5に二点鎖線で示すようにモニタ10の頂部(ローラ12が設けられた部分)が開位置にあるリッド1aとほぼ平行に移動するようカム溝31の形状が定められているので、モニタ10が倒れてもリッド1aが閉じ方向に移動することはない。これによりあたかもディスプレイ10がリッド1aとは無関係に移動しているように見え、高級感が損われることがない。
【0016】
一方、図5の状態になると、図8に二点鎖線で示すようにフォロアピン11aが係合部材71と係合し、以降は係合部材71を案内溝34に沿ってばね72の付勢力に抗して移動させる。したがってモニタ10には、フォロアピン11aおよび係合部材71を介してばね72の付勢力が作用することになる。その後、図6の状態になるとスライドベース40が最先端に達し、不図示の検出スイッチがオンしてモータ62が停止される。
【0017】
図6の状態では、図16に示すように係合部材71が先端部に達してばね72が伸びきった状態となり、モニタ10にはばね72による最大ばね力が作用する。係合部材71は、図17の拡大図に示すように斜めのエッジがフォロアピン11aの図示右上部に係合しているので、フォロアピン11aはばね72の付勢によって長孔42aの内壁W1およびカム溝31の内壁W2の双方に押圧されることになる。これによりフォロアピン11aの長孔42aに対するガタおよびカム溝31に対するガタがいずれも解除され、モニタ10の車両前後方向および上下方向のガタつきをともに防止できる。
【0018】
ところで、本実施の形態ではモニタ10の使用時における姿勢(角度)が図5の状態と図6の状態との間で複数段階に調節可能とされる。例えば図6の状態で角度調整操作を行うと、モータ62が所定量だけ逆転し、上述とは逆の動作でモニタ角度が所定角度だけ変更される。このようにモニタ角度調整が可能な範囲では、いずれのモニタ角度でもフォロアピン11aが係合部材71に係合しており、モニタ10には上記ばね72のばね力が作用する。係合部材71は、上述したように案内溝34に沿って移動するが、案内溝34はカム溝31に対応した形状となっているので、フォロアピン11aが係合するカム溝31の勾配が変化しても内壁W2とフォロアピン11aとの当接点に対する係合部材71の位置および姿勢は一定であり、フォロアピン11aは常に壁面W2をほぼ同一方向に押圧する。一方、長孔42aは常に垂直方向に延在しているので、その内壁W1に対するフォロアピン11aの押圧方向もほぼ一定である。したがって、モニタ10がいずれの位置に設定されていてもモニタ10の車両前後方向および上下方向のガタつきを確実に防止できる。
【0019】
使用後にモニタ10を格納するための操作を行うと、モータ62が逆転され、上述と逆の動作によりモニタ10が格納位置に駆動される。その際、リッド1aはモニタ10が直立するまでは動かず、それ以降は不図示のばねの付勢力によりモニタ10の格納動作に追従して閉じてゆく。また直立姿勢でフォロアピン11aと係合部材71との係合が解除され、以降はモニタ10にはばね72の付勢力は作用しない。このようにモニタ角度調整が可能な範囲外では、モニタ10にばね72の付勢力が作用しないので、モータに不要な負荷を与えることがない。
【0020】
以上の実施の形態の構成において、フォロアピン11aがモニタ係合部を、スライドベース40が移動部材を、長孔42aが第1の係合部を、カム部材30がガイド部材を、カム溝31が第2の係合部を、リンク80が姿勢変更部材を、係合部材71およびばね72が付勢手段を、案内溝34が案内部材をそれぞれ構成する。
【0021】
−第2の実施の形態−
図18〜図26により本発明の第2の実施の形態を説明する。
本実施の形態は、車両の天井に取り付けられる吊り下げ式のディスプレイ装置に適用したものである。
図18は本発明に係る車載用吊り下げ式ディスプレイ装置の概略斜視図である。このディスプレイ装置は、車室の天井に固着される筐体110と、筐体110内に配置されるモニタ120とを有する。モニタ120は、筐体110内に収容される収容位置と、筐体110から突出する使用位置との間で移動可能とされ、その移動はリモコンRMの操作に応答して電動にて行われる。以下、この電動によるモニタ動作を実現するための構成について詳述する。
【0022】
図19は筐体110の内部構成を示す平面図(車両装着状態では下から見上げた図)、図20は筐体110内部を側方から見た図である。筐体110の車両後方側空間(A方向側空間)にはモニタ120を収容する収容部CSが設けられ、それよりも車両前方側にモニタ駆動用の動力発生装置130が設けられる。動力発生装置130は、略コ字状のスライダ140をスライドさせることでモニタ120を駆動するものである。スライダ140は、ラック部141aおよび起立部141bをそれぞれ有する左右一対のスライド部141と、両スライド部141を連結する連結部142とから成り、左右の起立部141bに突設されたガイドピン41cがカム部材150の直進溝151(図4)に係合している。起立部141bには、図20に示すように車両上下方向の長孔141dが形成され、ここに後述するモニタ120のフォロアピン121aが係合される。
【0023】
図19において、動力発生装置130は1つのモータ131を備え、モータ131の出力軸に取り付けられたウォーム131aの回転が複数のギアG1〜G6を介してピニオンPG1に伝達される。ピニオンPG1は軸部材132を介してピニオンPG2に連結され、これらのピニオンPG1,PG2がスライダ140の左右ラック部141aに噛み合っている。したがって、ピニオンPG1,PG2の回転によりラック部141aを介してスライダ140が車両前後方向(B−A方向)にスライド移動し、その際、カム部材150の直進溝151に係合するガイドピン41cによりスライダ140の移動が案内される。モータ131,ギアG1〜G6および軸部材132はブラケットBR1〜BR4を介して筐体天板111に固定される。
【0024】
カム部材150は、筐体110の両側板112の内面に沿ってそれぞれ設けられ、図21の如く直進溝151の下方にカム溝152を有する。カム溝152は、B方向端部(車両前方側端部)から中間位置にかけては略水平に延在するが、中間位置からA方向端部(車両後方側端部)にかけては下方に傾斜している。このカム溝152にモニタ120のフォロアピン121aが係合される。カム溝152の更に下方には係合部材161の移動を案内する案内溝153が設けられ、係合部材161の裏面側に突設されたピン161aが案内溝153に係合されている。係合部材161の先端は常にカム溝152に突出し、上記フォロアピン121aに係合する。係合部材161とカム部材150のばね掛け154との間には引張ばね162が介装され、このばね162の付勢力により係合部材161を介してモニタ120が付勢される。156はばね162の伸縮を案内するための案内溝である。
【0025】
左右カム部材150の下部に設けられたレバー取付部LCには、左右レバー70の一端がそれぞれ回動可能に連結され、レバー170の他端はモニタ120の両側面に回動可能に連結される。モニタ120の上面左右部にはブラケット121を介してフォロアピン121aが突設され、このフォロアピン121aが上述したようにスライダ起立部141bに形成された長孔141dを貫通してカム部材150のカム溝152に係合される。レバー170の他端と筐体側板112に固着されたばね掛け12aとの間には引張ばね15が介装され、このばね115の付勢力によりレバー170がカム部材150に対して図20の時計回り方向に付勢される。
【0026】
以上のように構成されたディスプレイ装置のモニタ動作を説明する。
図20ではモニタ120が収容状態にあり、モニタ角度(モニタ120のA−B方向に対する角度)は約0度である。スライダ140は最もB方向側の位置に位置し、モニタ120のフォロアピン121aは長孔141dの上端部で、かつカム溝152のB方向端部に位置している。ばね115はレバー170を介してモニタ120を収容方向(突出阻止方向)に付勢している。
【0027】
この状態でリモコンRM(図1)によりモニタ120を突出させるための操作を行うと、動力発生装置130のモータ131が正転され、その回転がギアG1〜G6およびピニオンPG1,PG2を介してラック41aに伝達され、スライダ140がA方向にスライド移動する。スライダ140の移動により長孔141dの壁面がフォロアピン121aをカム溝152に沿って水平に押動し、モニタ120を駆動する。このモニタ120の動きに連動してレバー170がばね115の付勢力に抗して筐体110に対して回動し、図示二点鎖線で示す如くモニタ120の姿勢(角度)を変える。
【0028】
その後、図22の状態に至ると、モニタ120はほぼ垂直状態となり、このとき、図21に示すようにフォロアピン121aが係合部材161に係合する。したがって、これ以降はフォロアピン121aがばね162の付勢力に抗して係合部材161を溝156に沿って移動させ、モニタ120にはばね162の付勢力が作用する。スライダ140は更に移動を続け、図23のようにフォロアピン121aがカム溝152の水平部の端部に達すると、モニタ角度は約105度となる。その後、フォロアピン121aはスライダ140の長孔141dを下方に移動しつつカム溝152の傾斜部に沿って移動し、図24の状態を経て図25の状態に至る。図25の状態に至ったことが不図示の検出機構により検出されると、モータ131が停止される。
【0029】
図25におけるモニタ角度は約140度であり、このとき図26に示すように係合部材161は溝153の端部に達しており、伸張したばね162によりフォロアピン121a、すなわちモニタ120が付勢されている。係合部材161は、第1の実施の形態と同様に斜めのエッジがフォロアピン121aに係合しているので、フォロアピン121aはばね162の付勢によって長孔141dの内壁およびカム溝152の内壁の双方に押圧されることになる。これによりフォロアピン121aの長孔141dに対するガタおよびカム溝152に対するガタがいずれも解除され、モニタ120の車両前後方向および上下方向のガタつきをともに防止できる。
【0030】
ところで、モニタの使用角度は図25の状態と図23の状態との間で複数段階に調節可能である。例えば図25の状態でリモコンRMにより調整操作を行うと、モータ130が所定量だけ逆転され、スライダ140が所定量だけB方向に移動してモニタ角度が変更される。この角度調整可能な範囲では、いずれのモニタ角度でもフォロアピン121aが係合部材161に係合しており、モニタ120には上記ばね162のばね力が作用する。係合部材161は、上述したように案内溝153に沿って移動するが、案内溝153はカム溝152に対応した形状となっているので、フォロアピン121aが係合するカム溝152の勾配が変化してもカム溝152の内壁とフォロアピン121aとの当接点に対する係合部材161の位置および姿勢は一定であり、フォロアピン121aは常に溝壁面をほぼ同一方向に押圧する。一方、長孔141dは常に垂直方向に延在しているので、その内壁に対するフォロアピン121aの押圧方向もほぼ一定である。したがって、モニタ120がいずれの位置に設定されていてもモニタ120の車両前後方向および上下方向のガタつきを確実に防止できる。
【0031】
モニタ120を収容するための操作を行うと、動力発生装置130のモータ131が逆転され、上述と逆の動作でモニタ120が収容状態に向けて駆動され、モニタ120が収容状態に達するとモータ131が停止される。このモニタ収容動作時、図22の状態になるとフォロアピン121aと係合部材161との係合が解除され、以降はモニタ120にはばね161の付勢力は作用しない。このようにモニタ角度調整が可能な範囲外では、モニタ120にばね162の付勢力が作用しないので、モータに不要な負荷を与えることがない。
【0032】
以上の実施の形態の構成において、フォロアピン121aがモニタ係合部を、スライダ140が移動部材を、長孔141dが第1の係合部を、カム部材150がガイド部材を、カム溝152が第2の係合部を、レバー170が姿勢変更部材を、係合部材161およびばね162が付勢手段を、案内溝153が案内部材をそれぞれ構成する。
【0033】
なお、第1および第2の係合部は溝や孔に限定されず、フォロアピンの移動を案内する突条であってもよい。またモニタの角度調節が可能な範囲においてのみ付勢手段の付勢力がモニタに作用するようにしたが、モニタ移動範囲全般にわたって付勢力が作用するよう構成してもよい。
【0034】
【発明の効果】
本発明によれば、移動部材およびガイド部材の動作によりモニタを駆動するものにおいて、モニタ係合部を移動部材の第1の係合部およびガイド部材の第2の係合部の双方に押圧するようモニタを付勢するようにしたので、車両の振動等に起因するモニタの移動部材およびガイド部材の双方に対するガタつきが防止できる。
モニタが収容状態から所定の中間状態に達するまでは上記付勢力がモニタに作用しないようにすれば、モニタを停止させる範囲で上記ガタつきを防止でき、またそれ以外の範囲ではモニタ駆動に対して不要な負荷が加わるのを防止できる。付勢手段を構成する付勢係合部材がモニタ係合部に係合することにより、ばね部材の付勢力がモニタ係合部を第1および第2の係合部の双方に押圧する力として作用するようにすれば、第1および第2の係合部にそれぞれ対応する2種類のばね部材を設ける必要がなく、部品点数の低減が図れる。付勢係合部材を案内する案内部材を設け、付勢係合部材に係合するモニタ係合部が、第1および第2の係合部に対して常に同一方向に押圧されるようにすれば、モニタをいずれの位置で停止させても上記ガタつきを確実に防止できる。

As shown in FIG. 9, a monitor driving motor 62 is attached to the bottom plate 41 of the slide base 40 via a plate-like motor bracket 61. A worm 62a is attached to the output shaft of the motor 62, and the driving force of the motor 62 is transmitted to the gear member 64 with a clutch via the worm 62a and the worm wheel 63, and then to a pinion via a reduction gear train (not shown). 65 (FIG. 7). As the pinion 65 rotates, the slide base 40 moves in the AB direction via the rack 51a.
[0010]
As shown in FIG. 10, the monitor 10 has a display screen 13 on the front surface, brackets 11 are fixed to the left and right side surfaces, and follower pins 11 a project from the lower ends of the brackets 11. These follower pins 11 a pass through the long holes 42 a on the side surface of the slide base 40 described above and engage with the cam grooves 31 of the cam member 30. Reference numerals 14 denote shaft support portions provided on both side surfaces of the monitor 10.
[0011]
A roller 12 as shown in FIG. 11 is attached to the inside of the monitor 10 via a base 13, and a part of the roller 12 protrudes from the center of the corner between the upper surface and the back surface of the monitor 10. The roller 12 has a bush 12 a and a rubber contact portion 12 b disposed around the bush 12 a, and is rotatably supported on the base 13 via a shaft 14. A compression spring 15 for backlash is interposed between one end of the bush 12a and the base 13, and the roller 12 is pressed to the right in the drawing by the spring 15.

Each of the cam members 30 is pivotally supported by a shaft support portion 33 protruding from the cam member 30. Both ends of a tension coil spring 91 for rattling are hooked on the spring hooks 81a of the link portions 81 and the spring hooks 22a of the housing side plate 22, whereby the link member 80 is always in the clockwise direction of FIG. Be energized.
[0013]
The operation of the in-vehicle display device configured as described above will be described in detail.
In the storage position shown in FIG. 2, the monitor 10 takes a recumbent posture with the screen 13 facing downward, and is completely stored in the housing 20, that is, in the dashboard 1. At this time, the lid 1a of the dashboard 1 is closed by a biasing force of a spring (not shown) and is not in contact with the roller 12 of the monitor 10. The slide base 40 is in the position shown in FIG. 9 (behind the monitor 10), and the monitor 10 is biased by the tension spring 91 in the direction of holding the storage position via the link member 80. As a result, even if vibrations occur in the vehicle, the monitor 10 does not rattle and the generation of unpleasant noise can be prevented.
[0014]
When a predetermined monitor protrusion operation is performed, the motor 62 is driven to rotate in the forward direction, and the rotation is transmitted to the left and right pinions 65 via the worm wheel 63, the gear member 64, and a reduction gear mechanism (not shown). The slide base 40 starts moving in the direction B in FIG. The movement of the slide base 40 is guided by the guide groove 51 b of the rack member 51 and the guide groove 32 of the cam member 30. As the slide base 40 moves, the end face of the long hole 42a (FIG. 8) presses the cam follower 11a of the monitor 10 in the B direction, and the follower pin 11a moves in the cam groove 31 while moving the long hole 42a upward. In conjunction with this, the link member 80 rotates with respect to the housing 20 to change the posture (angle) of the monitor 10. Due to the action of the slide base 40, the cam member 30, and the link member 80, the monitor 10 gets up while moving as shown in FIG. The posture of the monitor 10 at each position is determined by the shape of the cam groove 31 and the connection position of the link member 80.
[0015]
When the monitor 10 is raised, the roller 12 comes into contact with the lower surface of the lid 1a and pushes it open while rolling on the lid 1a. The monitor 10 rises smoothly until it reaches the state of FIG. 5 through the states of FIGS. 2 to 3 and 4 in order, and in the state of FIG. 5, the lid 1a is in the most open state. Thereafter, the monitor 10 falls in the opposite direction. At that time, as shown by a two-dot chain line in FIG. 5, the top of the monitor 10 (the portion where the roller 12 is provided) moves substantially parallel to the lid 1a in the open position. The shape of the cam groove 31 is determined so that the lid 1a does not move in the closing direction even if the monitor 10 is tilted. As a result, the display 10 appears as if it is moving regardless of the lid 1a, and the sense of quality is not impaired.
[0016]
On the other hand, in the state of FIG. 5, the follower pin 11 a engages with the engaging member 71 as indicated by a two-dot chain line in FIG. 8, and thereafter, the engaging member 71 is applied to the biasing force of the spring 72 along the guide groove 34. Move against. Accordingly, the urging force of the spring 72 acts on the monitor 10 via the follower pin 11a and the engaging member 71. Thereafter, when the state shown in FIG. 6 is reached, the slide base 40 reaches the forefront, a detection switch (not shown) is turned on, and the motor 62 is stopped.
[0017]
In the state of FIG. 6, the engaging member 71 reaches the distal end portion and the spring 72 is fully extended as shown in FIG. 16, and the maximum spring force by the spring 72 acts on the monitor 10. As shown in the enlarged view of FIG. 17, the engaging member 71 has an oblique edge engaged with the upper right portion of the follower pin 11a in the figure, so that the follower pin 11a is biased by the spring 72 and the inner wall W1 of the long hole 42a and the cam It is pressed by both inner walls W2 of the groove 31. As a result, the backlash of the follower pin 11a with respect to the long hole 42a and the backlash with respect to the cam groove 31 are released, and the backlash of the monitor 10 in the vehicle longitudinal direction and the vertical direction can be prevented.
[0018]
By the way, in this embodiment, the posture (angle) when the monitor 10 is used can be adjusted in a plurality of stages between the state of FIG. 5 and the state of FIG. For example, when the angle adjustment operation is performed in the state of FIG. 6, the motor 62 reverses by a predetermined amount, and the monitor angle is changed by a predetermined angle by the reverse operation to the above. Thus, in the range in which the monitor angle can be adjusted, the follower pin 11 a is engaged with the engaging member 71 at any monitor angle, and the spring force of the spring 72 acts on the monitor 10. The engaging member 71 moves along the guide groove 34 as described above. However, since the guide groove 34 has a shape corresponding to the cam groove 31, the gradient of the cam groove 31 with which the follower pin 11a is engaged changes. Even so, the position and posture of the engaging member 71 with respect to the contact point between the inner wall W2 and the follower pin 11a are constant, and the follower pin 11a always presses the wall surface W2 in substantially the same direction. On the other hand, since the long hole 42a always extends in the vertical direction, the pressing direction of the follower pin 11a against the inner wall W1 is also substantially constant. Therefore, backlash of the monitor 10 in the vehicle longitudinal direction and the vertical direction can be reliably prevented regardless of the position of the monitor 10 set.
[0019]
When an operation for storing the monitor 10 is performed after use, the motor 62 is reversed, and the monitor 10 is driven to the storage position by the reverse operation to that described above. At that time, the lid 1a does not move until the monitor 10 stands upright, and thereafter, the lid 1a is closed following the storing operation of the monitor 10 by the biasing force of a spring (not shown). Further, the engagement between the follower pin 11a and the engaging member 71 is released in the upright posture, and thereafter, the biasing force of the spring 72 does not act on the monitor 10. In this way, outside the range in which the monitor angle can be adjusted, the biasing force of the spring 72 does not act on the monitor 10, so that no unnecessary load is applied to the motor.
[0020]
In the configuration of the above embodiment, the follower pin 11a is the monitor engaging portion, the slide base 40 is the moving member, the long hole 42a is the first engaging portion, the cam member 30 is the guide member, and the cam groove 31 is the cam groove 31. The second engaging portion, the link 80 constitutes a posture changing member, the engaging member 71 and the spring 72 constitute urging means, and the guide groove 34 constitutes a guiding member.
[0021]
-Second Embodiment-

The cam member 150 is engaged with a rectilinear groove 151 (FIG. 4). As shown in FIG. 20, a long hole 141d in the vehicle vertical direction is formed in the upright portion 141b, and a follower pin 121a of the monitor 120 described later is engaged therewith.
[0023]
In FIG. 19, the power generation device 130 includes one motor 131, and the rotation of the worm 131a attached to the output shaft of the motor 131 is transmitted to the pinion PG1 via a plurality of gears G1 to G6. The pinion PG1 is connected to the pinion PG2 via the shaft member 132, and these pinions PG1 and PG2 mesh with the left and right rack portions 141a of the slider 140. Therefore, the slider 140 slides in the vehicle front-rear direction (B-A direction) via the rack portion 141a by the rotation of the pinions PG1 and PG2, and at this time, the guide pin 41c that engages with the rectilinear groove 151 of the cam member 150 The movement of the slider 140 is guided. The motor 131, the gears G1 to G6, and the shaft member 132 are fixed to the housing top plate 111 via brackets BR1 to BR4.
[0024]
The cam members 150 are respectively provided along the inner surfaces of the side plates 112 of the housing 110, and have cam grooves 152 below the rectilinear grooves 151 as shown in FIG. The cam groove 152 extends substantially horizontally from the B-direction end (vehicle front side end) to the intermediate position, but is inclined downward from the intermediate position to the A-direction end (vehicle rear side end). Yes. The follower pin 121a of the monitor 120 is engaged with the cam groove 152. A guide groove 153 that guides the movement of the engagement member 161 is provided further below the cam groove 152, and a pin 161 a that protrudes from the back surface side of the engagement member 161 is engaged with the guide groove 153. The tip of the engagement member 161 always protrudes into the cam groove 152 and engages with the follower pin 121a. A tension spring 162 is interposed between the engagement member 161 and the spring hook 154 of the cam member 150, and the urging force of the spring 162 biases the monitor 120 via the engagement member 161. Reference numeral 156 denotes a guide groove for guiding expansion and contraction of the spring 162.
[0025]
One end of each of the left and right levers 70 is rotatably connected to the lever mounting portion LC provided at the lower portion of the left and right cam members 150, and the other end of the lever 170 is rotatably connected to both side surfaces of the monitor 120. . A follower pin 121a protrudes from the left and right upper portions of the monitor 120 via a bracket 121. The follower pin 121a passes through the long hole 141d formed in the slider upright portion 141b as described above, and the cam groove 152 of the cam member 150 is inserted. Is engaged. A tension spring 15 is interposed between the other end of the lever 170 and the spring hook 12a fixed to the casing side plate 112, and the biasing force of the spring 115 causes the lever 170 to rotate clockwise with respect to the cam member 150 in FIG. Biased in the direction.
[0026]
The monitor operation of the display device configured as described above will be described.
In FIG. 20, the monitor 120 is in the housed state, and the monitor angle (the angle with respect to the AB direction of the monitor 120) is about 0 degrees. The slider 140 is located at the position closest to the B direction, and the follower pin 121a of the monitor 120 is located at the upper end of the long hole 141d and at the end of the cam groove 152 in the B direction. The spring 115 urges the monitor 120 through the lever 170 in the accommodation direction (projection prevention direction).
[0027]
When an operation for projecting the monitor 120 is performed by the remote controller RM (FIG. 1) in this state, the motor 131 of the power generating device 130 is rotated forward, and the rotation is racked via the gears G1 to G6 and the pinions PG1 and PG2. The slider 140 is slid in the A direction. Due to the movement of the slider 140, the wall surface of the long hole 141 d pushes the follower pin 121 a horizontally along the cam groove 152 to drive the monitor 120. In conjunction with the movement of the monitor 120, the lever 170 rotates with respect to the casing 110 against the biasing force of the spring 115, and changes the posture (angle) of the monitor 120 as shown by a two-dot chain line in the drawing.
[0028]
Thereafter, when the state shown in FIG. 22 is reached, the monitor 120 is in a substantially vertical state, and at this time, the follower pin 121a is engaged with the engaging member 161 as shown in FIG. Therefore, thereafter, the follower pin 121a moves the engagement member 161 along the groove 156 against the biasing force of the spring 162, and the biasing force of the spring 162 acts on the monitor 120. The slider 140 continues to move, and when the follower pin 121a reaches the end of the horizontal portion of the cam groove 152 as shown in FIG. 23, the monitor angle becomes about 105 degrees. Thereafter, the follower pin 121a moves along the inclined portion of the cam groove 152 while moving downward in the long hole 141d of the slider 140, and reaches the state of FIG. 25 through the state of FIG. When the detection mechanism (not shown) detects that the state of FIG. 25 has been reached, the motor 131 is stopped.
[0029]
The monitor angle in FIG. 25 is about 140 degrees. At this time, as shown in FIG. 26, the engaging member 161 reaches the end of the groove 153, and the follower pin 121a, that is, the monitor 120 is urged by the extended spring 162. ing. Since the engaging member 161 has an oblique edge engaged with the follower pin 121a as in the first embodiment, the follower pin 121a is biased by the spring 162 to the inner wall of the long hole 141d and the inner wall of the cam groove 152. It will be pressed by both. As a result, the looseness of the follower pin 121a with respect to the long hole 141d and the looseness of the cam groove 152 are released, and the backlash of the monitor 120 in the vehicle longitudinal direction and the vertical direction can be prevented.
[0030]
By the way, the use angle of the monitor can be adjusted in a plurality of stages between the state of FIG. 25 and the state of FIG. For example, when an adjustment operation is performed by the remote controller RM in the state of FIG. 25, the motor 130 is reversed by a predetermined amount, and the slider 140 is moved in the B direction by a predetermined amount to change the monitor angle. In this angle adjustable range, the follower pin 121a is engaged with the engaging member 161 at any monitor angle, and the spring force of the spring 162 acts on the monitor 120. The engaging member 161 moves along the guide groove 153 as described above. However, since the guide groove 153 has a shape corresponding to the cam groove 152, the gradient of the cam groove 152 with which the follower pin 121a engages changes. Even so, the position and posture of the engaging member 161 with respect to the contact point between the inner wall of the cam groove 152 and the follower pin 121a are constant, and the follower pin 121a always presses the groove wall surface in substantially the same direction. On the other hand, since the long hole 141d always extends in the vertical direction, the pressing direction of the follower pin 121a against the inner wall is also substantially constant. Therefore, the backlash of the monitor 120 in the vehicle front-rear direction and the vertical direction can be reliably prevented regardless of the position of the monitor 120.
[0031]
When the operation for housing the monitor 120 is performed, the motor 131 of the power generation device 130 is reversed, the monitor 120 is driven toward the housed state by the reverse operation to the above, and when the monitor 120 reaches the housed state, the motor 131 is driven. Is stopped. During the monitor housing operation, when the state shown in FIG. 22 is reached, the engagement between the follower pin 121a and the engagement member 161 is released, and thereafter the biasing force of the spring 161 does not act on the monitor 120. In this way, outside the range in which the monitor angle can be adjusted, the biasing force of the spring 162 does not act on the monitor 120, so that no unnecessary load is applied to the motor.
[0032]
In the configuration of the above embodiment, the follower pin 121a is the monitor engaging portion, the slider 140 is the moving member, the long hole 141d is the first engaging portion, the cam member 150 is the guide member, and the cam groove 152 is the first groove. 2, the lever 170 constitutes a posture changing member, the engaging member 161 and the spring 162 constitute urging means, and the guide groove 153 constitutes a guide member.

The first and second engaging portions are not limited to grooves and holes, and may be protrusions that guide the movement of the follower pin. Further, the urging force of the urging means is applied to the monitor only within the range in which the monitor angle can be adjusted, but the urging force may be applied to the entire monitor moving range.

【The invention's effect】
According to the present invention, in the case where the monitor is driven by the movement of the moving member and the guide member, the monitor engagement portion is pressed against both the first engagement portion of the movement member and the second engagement portion of the guide member. Since the monitor is biased, it is possible to prevent rattling of both the moving member and the guide member of the monitor due to the vibration of the vehicle.
By preventing the urging force from acting on the monitor until the monitor reaches the predetermined intermediate state from the housed state, the rattling can be prevented in the range where the monitor is stopped, and in other ranges, the monitor is not driven. Unnecessary load can be prevented. As the urging engagement member constituting the urging means engages with the monitor engagement portion, the urging force of the spring member presses the monitor engagement portion against both the first and second engagement portions. If it acts, it is not necessary to provide two types of spring members respectively corresponding to the first and second engaging portions, and the number of parts can be reduced. A guide member for guiding the biasing engagement member is provided, and the monitor engagement portion that engages with the biasing engagement member is always pressed against the first and second engagement portions in the same direction. Thus, the play can be reliably prevented regardless of the position of the monitor.
