The click feeling is generated by the movement of the pressing part 13 on the slanted guiding surface 23 while being pressed downward by the rocking operation of the operation part 20, and also the click feeling is generated by the deformation and buckling of the elastic body 33 while being pressed downward. Those click feelings are generated almost simultaneously. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は操作部を揺動させてオンオフ操作を行う操作スイッチに関し、より詳細には操作部の揺動時に適度な節度感を発する操作スイッチに関する。
【0002】
【従来の技術】
例えば自動車の車高調節スイッチやトラクション調整スイッチとして、操作部を双方向に揺動させてスイッチのオンオフ操作を行う操作スイッチがある。このような操作スイッチは通常、操作者にスイッチのオンオフ状態がわかるように、揺動時に適度な節度感を発する構造を有している。
従来、このような節度感を発生させる構造としては、例えば特許文献1に示すように、操作部の下部にガイド斜面を形成し、このガイド斜面に対してバネで付勢された駆動棒を押圧させ、操作部の揺動に伴って、この駆動棒をガイド斜面上を移動させる構成がある。このガイド斜面には、両側の斜面の途中にそれぞれ段差が設けられている。揺動操作により操作部を揺動させると、駆動棒がガイド斜面上を移動し、この駆動棒がガイド斜面上の段差を乗越えることよって節度感を発生する構成となっている。またこの駆動棒は、バネの復元力によってガイド斜面を押圧し、操作部を初期位置に復帰させる。また特許文献1に記載の操作スイッチでは、接点部に薄厚状のゴム板を介在させ、このゴム板が押圧された際の弾性復元力も、操作部を初期位置に復帰させることに寄与している。
また他の構造としては、基板との接点部をゴム製にして、このゴム製の接点部を押圧することによって座屈変形させ、この座屈変形する際の変形抵抗の変化によって節度感を発生させる構成がある。
【0003】
【特許文献1】
登録実用新案第2519813号公報(図1)
【0004】
【発明が解決しようとする課題】
このようにバネによる押圧機構により、あるいはゴムの座屈変形により節度感を作り出した場合、それぞれバネやゴムの有する特有の感触からくる節度感が発生する。これらの節度感は、操作者がスイッチのオンオフ状態を確認するためには十分であるが、近年の自動車等の細部の充実化に伴い、操作スイッチにも今までにない新たな節度感を有するものが要求されるようになってきている。ここで、上述の特許文献1に記載された操作スイッチでは、接点部にゴム板を介在させている。しかし、このゴム板は押圧されて変形し、弾性復元力は発生させるものの、座屈変形はしないので節度感を発生させるものではない。
また、バネやゴムは操作部の揺動によって繰り返して負荷がかかることにより劣化し、望ましい復元力が発生しなくなる可能性がある。あるいは基板との接点部に接触不良を引き起こす可能性もある。
【0005】
本発明は以上の問題点を鑑みてなされたものであり、今までにない新たな節度感を発生させ、また復元力を発生する部分の負荷を軽減した操作スイッチを提供することを目的とする。
【0006】
【課題を解決するための手段】
上記課題を解決するため本発明は、基板接点を有する基板上に配置されるスイッチ本体と、該スイッチ本体に揺動自在に保持された操作部と、該操作部の操作揺動に連動して上記基板接点に対してオンオフ動作を行う接点部とを備えた操作スイッチにおいて、上記スイッチ本体は弾性部材によって上向きに付勢される押圧部を有し、上記操作部はその下面の中央部に略V字状のガイド斜面が形成され、該ガイド斜面に対して上記押圧部を当接させ、上記接点部は上記操作部の揺動に伴って上下動する押棒部と、該押棒部の下方に位置し押棒部に押圧されて座屈変形する弾性体と、該弾性体の座屈変形時に上記基板接点と接触する弾性体接点とからなり、上記操作部の操作揺動により、上記押圧部は上記ガイド斜面によって下方に押圧されながらガイド斜面上を移動することで節度感を発生し、上記弾性体は上記押棒部によって下方に押圧されながら座屈変形をすることで節度感を発生し、これらの節度感を略同時に発生させることを特徴として構成されている。
【0007】
また本発明は、上記ガイド斜面は略V字状に対向する各面をそれぞれ膨出させてなり、上記操作部の操作揺動により、上記押圧部は上記ガイド斜面によって下方に押圧されながらガイド斜面の膨出部分を乗越えることで節度感を発生することを特徴として構成されている。
【0008】
また本発明は、上記接点部の弾性体は上記押棒部に連設され下面に上記弾性体接点を有する本体部と、該本体部の下部から釣鐘状に形成された薄肉状の変形部からなり、上記変形部は上記押棒部に押圧される上記本体部の移動に伴って内側に座屈変形し、上記本体部の弾性体接点を上記基板接点に接触させることを特徴として構成されている。
【0009】
また本発明は、上記押棒部は初期状態において上端部が上記操作部の端部に当接することを特徴として構成されている。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を参照しつつ詳細に説明する。図1は本発明の実施形態における操作スイッチの断面図、図2は操作部をθだけ傾斜させた際の操作スイッチの断面図、図3は操作部をθだけ傾斜させた際の操作スイッチの断面図である。なお、本実施形態のおいては、節度感を発生する前後の角度を概念的にθ、θとして説明する。
【0011】
本実施形態における操作スイッチ1は、例えば自動車の車高調整スイッチやトラクション調整スイッチとして使用されるもので、操作部20を上下あるいは左右に揺動させて両側でスイッチのオンオフ操作をするためのものである。操作スイッチ1は図1に示すように、自動車の車載パネル等の内側に設けられた基板40上に固定されるスイッチ本体10、このスイッチ本体10の上部に揺動自在に設けられる操作部20、及びこの操作部20の揺動に連動して基板40上の回路を導通させる接点部30からなる。
【0012】
スイッチ本体10は操作スイッチ1の土台となるものであり、その略中央に上側に突出する矩形状の押圧機構部11を有する。この押圧機構部11はその略中央に断面円形の収容穴11aを有しており、この収容穴11aの内側にはコイルバネ12が収められている。さらにこの収納穴11aには、コイルバネ12の上部に、上端が半球面状に形成された駆動棒13が収められている。この駆動棒13は、スイッチ本体10に対して操作部20が取付けられることにより、後述する操作部20のガイド斜面23によって下向きに押込まれる。このように駆動棒13が下向きに押込まれることによって、駆動棒13の下部に位置するコイルバネ12が収縮し、これにより駆動棒13はコイルバネ12の復元力で上向きに付勢される。また、押圧機構部11の側面には、操作部20を保持するための円形凹状の被嵌合部14が設けられている。
【0013】
一方、このスイッチ本体10に取付けられる操作部20は、操作者が操作を行う操作ノブ21、この操作ノブ21の下部に形成されスイッチ本体10を略覆う断面略円弧状のカバー部22、及びこのカバー部22に連続状に形成された、操作部20をスイッチ本体10へ取付けるための取付部25からなる。
操作ノブ21は操作者が指で一方の面を押して操作部20を傾斜させるためのものであり、ある程度の肉厚を有する矩形状に形成されている。またこの操作ノブ21にはビニルなどで形成したノブカバー21aが被せられている。
カバー部22はスイッチ本体10の内部を保護すると共に、後述する接点部30の押棒部31を押圧する役割を果たす。なお、この押棒部31を押圧するために、カバー部22の端部はカバー押圧面24を有するように形成されている。またこのカバー部22の内面略中央には、駆動棒13の上部が当接する略V字状のガイド斜面23が形成されている。このガイド斜面23は、対向する各面がそれぞれ膨出するようにして形成されている。
取付部25は内側に突出する円筒状の嵌合部26を有し、スイッチ本体10の被嵌合部14にこの嵌合部26をはめ込むことにより、操作部20がスイッチ本体10に揺動自在に保持される。
【0014】
また接点部30は、操作部20のカバー押圧面24に押圧されて下方に移動する押棒部31、この押棒部31を上下方向に案内する棒案内部32、押棒部31の下方に位置し押棒部31の下端に押圧されて変形しつつ下降する弾性体33、及びこの弾性体33の下面に設けられる金属製の弾性体接点34からなる。このような接点部30はスイッチ本体10と一体的に形成してもよく、あるいは別部材として形成してもよい。
押棒部31の本体は円柱状に形成され、その上端が半球面状に形成されている。また、その下端は円盤状に形成されている。この押棒部31は、初期状態つまり操作部20が中央位置にある状態において、上端部がカバー押圧面24に当接している。
【0015】
棒案内部32は押棒部31と略同径の貫通孔を有しており、押棒部31を上下方向の移動に案内する。また棒案内部32の上面には操作部20のカバー押圧面24が当接し、操作部20の傾斜可能な角度を規制する役割を果たす。
弾性体33は絶縁性のゴムで形成され、略円柱状に形成され押棒部31の下端に押圧される本体部33aと、この本体部33aの下部から釣鐘状に形成された薄肉状の変形部33bを有する。本体部33aの上面は押棒部31の下端と連設しており、下面には弾性体接点34が設けられている。
【0016】
次に、このような操作スイッチ1の動作について説明する。なお、ここでは操作部20を左側に傾斜させた場合について説明するが、逆側に傾斜させても基板上の導通状態が異なること以外は同様である。また、操作スイッチ1を、操作部20が上下動するように設けた場合も同様である。
操作ノブ21に対して操作力が加わると、操作部20は取付部25の嵌合部26を中心として傾斜する。図2はθだけ傾斜させた際の図である。操作部20をθだけ傾斜させると、その分だけ駆動棒13はガイド斜面23上を移動する。このとき、ガイド斜面23の駆動棒13との接触部分は下方に移動するので、駆動棒13は下方に押圧され、駆動棒13の下部に位置するコイルバネ12が収縮し、復元力を発生させる。これによって駆動棒13はガイド斜面23を押圧する押圧部として働く。即ち、操作者が操作ノブ21から手を離すと、このコイルバネ12の復元力で上向きに付勢された駆動棒13によって、操作部20は中央位置に復帰する。またこのコイルバネ12の復元力によって、駆動棒13はガイド斜面23において、操作部20の傾斜に対する抗力を発生させる。この抗力によって、操作部20を傾斜させた際に操作感を与えることができる。
【0017】
また操作部20がθだけ傾斜することによって、押棒部31は上端がカバー部22のカバー押圧面24に押圧されて下方に移動する。これに伴い、押棒部31の下端と連設している本体部33aも下方に移動する。また本体部33aが下方に移動すると、変形部33bも変形し、これによって変形部33bは復元弾性力を発生させる。操作者が操作ノブ21から手を離すと、この変形部33bの復元弾性力で上向きに付勢された押棒部31によって、カバー押圧面24を介して操作部20は中央位置に復帰する。また変形部33bは、本体部33aが押圧されて変形するときに、変形抵抗を発生させる。この変形抵抗によって、操作部20を傾斜させた際に操作感を与えることができる。
【0018】
このように、操作部20を中央位置に復帰させるための復元力を、コイルバネ12とゴム製の変形部33bで分担することにより、従来のように一つの復元力のみで操作部20を中央位置に復帰させていた場合に比べ、コイルバネ12や変形部33bに加わる負荷加重が軽減する。またこれによって操作部20の動作音が軽減する。
また上述したように、押棒部31は初期状態において上端がカバー押圧面24に当接しているので、操作部20を傾斜させるとその直後から押棒部31の上端がカバー押圧面24に押圧されて下方に移動し、これに伴い本体部33aも下方に移動し変形部33bが変形して変形抵抗を発生させる。これによって、どの位置に操作部20を傾斜させても、コイルバネ12の復元力による駆動棒13のガイド斜面23に対する抵抗と、変形部33bによる変形抵抗が発生するので、統一した操作感を与えることができる。
【0019】
次に、図3に示すように、操作部20をθからθ(θ<θ)まで傾斜させた場合について説明する。操作部20をθまで傾斜させると、その分だけさらに駆動棒13は相対的にガイド斜面23上を移動する。このとき、駆動棒13がガイド斜面23の膨出部分を乗越えることによって節度感を発生する。つまり、ガイド斜面23は膨出するように形成されていることから、操作部20を傾斜させると、ガイド斜面23の駆動棒13に接する部分の傾斜は浅くなっていく。これにより、コイルバネ12の復元力によって駆動棒13がガイド斜面23に与える抗力のガイド斜面23に沿う方向の成分は小さくなり、傾斜操作の途中から必要な操作力が減少することによって節度感が発生する。
またこのとき、操作者が操作ノブ21から手を離すと、このコイルバネ12の復元力で上向きに付勢された駆動棒13により、操作部20が中央位置に復帰することは、操作部20をθだけ傾斜させたときと同様である。
【0020】
また操作部20がθだけ傾斜することによって、押棒部31の上端がカバー部22のカバー押圧面24に押圧されてさらに下方に移動し、本体部33aも下方に移動する。また本体部33aがさらに下方に移動すると、変形部33bは内側に座屈変形し、これによって変形部33bは節度感を発生させる。即ち、この変形部33bは変形する際に変形抵抗を発生させるが、本体部33aが下方に移動して変形部33bの変形が進むと、変形部33bはその押圧力に耐えられなくなり内側に折れ曲がる(座屈する)。座屈する際に変形抵抗は小さくなり、これによって節度感を発生させる。また、本体部33aがさらに下方に移動することにより、本体部33aの下面に設けた弾性体接点34が基板40上の基板接点41に接触し、基板40の導通状態を作り出す。
またこのとき、操作者が操作ノブ21から手を離すと、この変形部33bの復元弾性力で上向きに付勢された押棒部31により、カバー押圧面24を介して操作部20が中央位置に復帰することは、操作部20をθだけ傾斜させたときと同様である。
【0021】
このようなガイド斜面23と駆動棒13による節度感と、変形部33bによる節度感はほぼ同時に発生させる。具体的には、ガイド斜面23の膨出具合や駆動棒13の先端部の形状、コイルバネ12の材質や大きさ、さらに弾性体33の材質や変形部33bの形状、肉厚などを調整することにより、節度感が発生するタイミングは調整可能である。
このように、2種類の節度感をほぼ同時に発生させることにより、今までにない複合的な節度感を発生させることができる。またコイルバネ12の強さや材質、形状、さらには変形部33bの肉厚や形状、材質等を変更することにより、発生する節度感をその組み合わせによって自由に変更することができる。
【0022】
以上、本発明の実施形態について説明した。しかしながら、本発明は上記実施形態に記載された事項に限定されず、特許請求の範囲の記載に基づいてその変更、改良が可能である。例えば、上記実施形態においては、ガイド斜面を膨出状に形成し、駆動棒がガイド斜面の膨出部分を乗越えることによって節度感を発生する構成とした。しかし、本発明はこれに限られることなく、例えばガイド斜面上に駆動棒に比べて十分小さい段差を形成し、駆動棒がこの段差を乗越えることによって節度感を発生する構成とするなど、他の構成であっても良い。
【0023】
また、本実施形態ではコイルバネを用いることとしているが、駆動棒を上向きに付勢する部材については特にこれに限定する必要はなく、復元力を発生する弾性部材であればよい。ただし、異なる節度感を発生させるために、弾性体とは材質が異なることが望ましい。
さらに操作部については必ずしもこのような形状である必要はなく、例えば操作ノブを設ける形態ではなく、シーソー状の形態としてもよい。
【0024】
【発明の効果】
以上本発明によれば、操作部の操作揺動により、押圧部はガイド斜面によって下方に押圧されながらガイド斜面上を移動することで節度感を発生し、弾性体は押棒部によって下方に押圧されながら座屈変形をすることで節度感を発生し、これらの節度感を略同時に発生させることから、ガイド斜面と押圧部による節度感と弾性体の座屈変形による節度感が合わさった、複合的な節度感を発生させることができる。またこれらの節度感を、その形状や材質等を変形することにより変化させ、発生する節度感をその組み合わせによって自由に変更することができる。
さらに、操作部を中央位置に復帰させるための復元力を、スイッチ本体の弾性部材と接点部の弾性体で分担することにより、従来一つの復元力のみで操作部を中央位置に復帰させていた場合に比べ、弾性部材や弾性体に加わる負荷加重が軽減され、長寿命化を図ることができると共に、部品の小型化が可能となる。また操作部の動作音を軽減することができる。
【0025】
また本発明によれば、ガイド斜面は略V字状に対向する各面をそれぞれ膨出させてなり、操作部の操作揺動により、押圧部は上記ガイド斜面によって下方に押圧されながらガイド斜面の膨出部分を乗越えることで節度感を発生することから、操作スイッチに必要な節度感を容易に発生させることができる。
【0026】
また本発明によれば、接点部の弾性体は押棒部に連設され下面に弾性体接点を有する本体部と、本体部の下部から釣鐘状に形成された薄肉状の変形部からなり、変形部は押棒部に押圧される本体部の移動に伴って内側に座屈変形し、本体部の弾性体接点を基板接点に接触させることから、変形部が内側に折れ曲がって座屈変形し、座屈変形した後は変形抵抗は小さくなり、これによって節度感を発生させることができる。またこれと共に本体部の下面に設けた弾性体接点を基板接点に接触させて、基板の導通状態を作り出すことができる。
【0027】
また本発明によれば、押棒部は初期状態において上端部が操作部の端部に当接するから、操作部の傾斜角度が浅い状態でも押棒部が操作部に押圧され、この押棒部を介して弾性体が変形して変形抵抗を発生する。このことから、どの位置に操作部を傾斜させても、押圧部のガイド斜面に対する抵抗と、弾性体の変形抵抗が発生するので、統一した操作感を与えることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an operation switch that performs an on / off operation by swinging an operation unit, and more particularly, to an operation switch that generates an appropriate moderation feeling when the operation unit swings.
[0002]
[Prior art]
For example, as a vehicle height adjustment switch or a traction adjustment switch of an automobile, there is an operation switch for turning on and off a switch by bidirectionally swinging an operation unit. Such an operation switch usually has a structure that gives an appropriate sense of moderation when swinging so that the operator can know the on / off state of the switch.
Conventionally, as a structure for generating such a moderation feeling, for example, as shown in Patent Document 1, a guide slope is formed at a lower portion of an operation unit, and a drive rod biased by a spring is pressed against the guide slope. There is a configuration in which the drive rod is moved on a guide slope as the operation unit swings. The guide slope is provided with a step in the middle of both slopes. When the operation unit is rocked by the rocking operation, the drive rod moves on the guide slope, and the drive rod crosses a step on the guide slope to generate a sense of moderation. Further, the drive rod presses the guide slope by the restoring force of the spring, and returns the operation unit to the initial position. In the operation switch described in Patent Literature 1, a thin rubber plate is interposed in the contact portion, and the elastic restoring force when the rubber plate is pressed also contributes to returning the operation portion to the initial position. .
As another structure, the contact point with the substrate is made of rubber, and the rubber contact point is pressed to cause buckling deformation, and a moderation feeling is generated due to the change in deformation resistance at the time of this buckling deformation. There is a configuration to make it.

[Patent Document 1]
Registered Utility Model No. 2519813 (FIG. 1)
[0004]
[Problems to be solved by the invention]
When the moderation is created by the pressing mechanism using the spring or by the buckling deformation of the rubber, a moderation feeling is generated from the unique feeling of the spring or the rubber. These moderation feelings are sufficient for the operator to confirm the on / off state of the switch, but with the recent enrichment of automobiles and the like, the operation switches have a new moderation feeling that has never been seen before. Things are being required. Here, in the operation switch described in Patent Document 1 described above, a rubber plate is interposed at the contact portion. However, this rubber plate is deformed by being pressed and generates an elastic restoring force, but does not buckle and does not generate a sense of moderation.
Further, the spring or rubber may be deteriorated by repeatedly applying a load due to the swing of the operation unit, and may not generate a desired restoring force. Alternatively, there is a possibility that a contact failure occurs at a contact portion with the substrate.
[0005]
The present invention has been made in view of the above problems, and an object of the present invention is to provide an operation switch that generates a new sense of moderation and reduces the load on a portion that generates a restoring force. .
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a switch body disposed on a substrate having a substrate contact, an operation unit swingably held by the switch body, and an operation unit interlocked with the operation swing of the operation unit. An operation switch having a contact portion that performs an on / off operation with respect to the substrate contact, wherein the switch body has a pressing portion that is urged upward by an elastic member, and the operation portion is provided substantially at a central portion of a lower surface thereof. A V-shaped guide slope is formed, the pressing portion is brought into contact with the guide slope, and the contact portion is provided with a push rod portion that moves up and down with the swing of the operation portion, and a push bar portion below the push rod portion. An elastic body that is located and is buckled and deformed by being pressed by the push rod portion, and an elastic body contact that comes into contact with the substrate contact when the elastic body is buckled and deformed. While being pressed downward by the guide slope, A moderation feeling is generated by moving on the guide slope, and the elastic body generates a moderation feeling by being buckled and deformed while being pressed downward by the push rod portion, and these moderation feelings are generated substantially simultaneously. It is characterized by the following.
[0007]
Also, in the present invention, the guide slope is formed by bulging each of the opposing surfaces in a substantially V-shape, and the pressing portion is pressed downward by the guide slope by the operation swing of the operation portion. It is characterized by generating a sense of moderation by overcoming the bulging portion of.
[0008]
Further, according to the present invention, the elastic body of the contact portion includes a main body portion connected to the push rod portion and having the elastic body contact on the lower surface, and a thin deformed portion formed in a bell shape from a lower portion of the main body portion. The deformation portion is configured to buckle and deform inward with the movement of the main body portion pressed by the push rod portion, so that the elastic contacts of the main body portion contact the substrate contacts.
[0009]
Further, the present invention is characterized in that the upper end portion of the push rod portion contacts the end portion of the operation portion in an initial state.
[0010]

The operation switch 1 according to the present embodiment is used as, for example, a vehicle height adjustment switch or a traction adjustment switch, and is used to swing the operation unit 20 up and down or left and right to perform on / off operations of the switches on both sides. It is. As shown in FIG. 1, the operation switch 1 includes a switch body 10 fixed on a substrate 40 provided inside a vehicle-mounted panel or the like of an automobile, an operation unit 20 provided on the upper part of the switch body 10 so as to be swingable, And a contact section 30 for conducting a circuit on the substrate 40 in conjunction with the swing of the operation section 20.
[0012]
The switch body 10 serves as a base of the operation switch 1, and has a rectangular pressing mechanism 11 protruding upward at substantially the center. The pressing mechanism 11 has a housing hole 11a having a circular cross section substantially at the center thereof, and a coil spring 12 is housed inside the housing hole 11a. Further, a drive rod 13 whose upper end is formed in a hemispherical shape is accommodated in the accommodation hole 11 a above the coil spring 12. The drive rod 13 is pushed downward by a guide slope 23 of the operation unit 20 described later when the operation unit 20 is attached to the switch body 10. When the drive rod 13 is pushed downward in this manner, the coil spring 12 located below the drive rod 13 contracts, whereby the drive rod 13 is urged upward by the restoring force of the coil spring 12. A circular concave fitting portion 14 for holding the operation portion 20 is provided on a side surface of the pressing mechanism portion 11.
[0013]
On the other hand, an operation section 20 attached to the switch body 10 includes an operation knob 21 operated by an operator, a cover section 22 formed below the operation knob 21 and covering the switch body 10 and having a substantially arc-shaped cross section. An attachment portion 25 is formed on the cover portion 22 to attach the operation portion 20 to the switch body 10.
The operation knob 21 is for the operator to press one surface with a finger to tilt the operation unit 20 and is formed in a rectangular shape having a certain thickness. The operation knob 21 is covered with a knob cover 21a formed of vinyl or the like.
The cover portion 22 serves to protect the inside of the switch body 10 and to press a push rod portion 31 of a contact portion 30 described later. In order to press the push rod 31, the end of the cover 22 is formed to have a cover pressing surface 24. A substantially V-shaped guide slope 23 with which the upper part of the drive rod 13 contacts is formed substantially at the center of the inner surface of the cover portion 22. The guide slope 23 is formed such that the opposing surfaces swell.
The mounting portion 25 has a cylindrical fitting portion 26 protruding inward, and by fitting the fitting portion 26 into the fitted portion 14 of the switch body 10, the operating portion 20 can swing on the switch body 10. Is held.
[0014]
The contact portion 30 includes a push rod portion 31 that is pressed by the cover pressing surface 24 of the operation portion 20 and moves downward, a rod guide portion 32 that guides the push rod portion 31 in the vertical direction, and a push rod located below the push rod portion 31. The elastic body 33 is pressed by the lower end of the portion 31 and descends while deforming, and a metal elastic contact 34 provided on the lower surface of the elastic body 33. Such a contact portion 30 may be formed integrally with the switch body 10, or may be formed as a separate member.
The main body of the push rod portion 31 is formed in a cylindrical shape, and the upper end thereof is formed in a hemispherical shape. The lower end is formed in a disk shape. The upper end of the push rod portion 31 is in contact with the cover pressing surface 24 in an initial state, that is, in a state where the operation unit 20 is at the center position.
[0015]
The rod guide portion 32 has a through hole having substantially the same diameter as the push rod portion 31, and guides the push rod portion 31 to move in the vertical direction. Further, the cover pressing surface 24 of the operation unit 20 abuts on the upper surface of the rod guide unit 32, and plays a role of restricting the tiltable angle of the operation unit 20.
The elastic body 33 is formed of insulating rubber, is formed in a substantially cylindrical shape, and is pressed against the lower end of the push rod portion 31. A thin deformed portion formed in a bell shape from the lower portion of the main body portion 33a. 33b. The upper surface of the main body portion 33a is provided continuously with the lower end of the push rod portion 31, and an elastic contact 34 is provided on the lower surface.
[0016]
Next, the operation of the operation switch 1 will be described. Here, the case where the operation unit 20 is tilted to the left will be described, but the same applies even when the operation unit 20 is tilted to the opposite side except that the conduction state on the substrate is different. The same applies to the case where the operation switch 1 is provided so that the operation unit 20 moves up and down.
When an operation force is applied to the operation knob 21, the operation section 20 is inclined around the fitting section 26 of the mounting section 25. Figure 2 is a diagram of when is inclined by theta 1. When the operating unit 20 is inclined by theta 1, the drive rod 13 by that amount moves on the guide slope 23. At this time, the contact portion of the guide slope 23 with the drive rod 13 moves downward, so that the drive rod 13 is pressed downward, and the coil spring 12 located below the drive rod 13 contracts, generating a restoring force. Thus, the drive rod 13 functions as a pressing portion that presses the guide slope 23. That is, when the operator releases his / her hand from the operation knob 21, the operation unit 20 returns to the center position by the drive rod 13 urged upward by the restoring force of the coil spring 12. In addition, the drive rod 13 generates a drag against the inclination of the operation unit 20 on the guide slope 23 by the restoring force of the coil spring 12. With this drag, an operation feeling can be given when the operation unit 20 is inclined.
[0017]
Also by the operating portion 20 is inclined by theta 1, push rod 31 moves the upper end is pressed by the cover pressing face 24 of the cover portion 22 downward. Along with this, the main body 33a connected to the lower end of the push rod 31 also moves downward. Further, when the main body 33a moves downward, the deformable portion 33b also deforms, whereby the deformable portion 33b generates a restoring elastic force. When the operator removes his / her hand from the operation knob 21, the operating portion 20 returns to the center position via the cover pressing surface 24 by the push rod portion 31 urged upward by the restoring elastic force of the deformed portion 33b. The deforming portion 33b generates deformation resistance when the main body portion 33a is pressed and deformed. With this deformation resistance, an operation feeling can be given when the operation unit 20 is inclined.
[0018]
As described above, the restoring force for returning the operating portion 20 to the center position is shared by the coil spring 12 and the rubber deforming portion 33b, so that the operating portion 20 can be moved to the center position with only one restoring force as in the related art. , The load applied to the coil spring 12 and the deformed portion 33b is reduced. This also reduces the operation sound of the operation unit 20.
Further, as described above, since the upper end of the push rod portion 31 is in contact with the cover pressing surface 24 in the initial state, the upper end of the push rod portion 31 is pressed by the cover pressing surface 24 immediately after the operating portion 20 is tilted. The body 33a moves downward, and the body 33a also moves downward, thereby deforming the deformable portion 33b to generate deformation resistance. Thus, no matter what position the operating unit 20 is tilted, the resistance of the drive rod 13 to the guide slope 23 due to the restoring force of the coil spring 12 and the deformation resistance due to the deformation unit 33b are generated. Can be.
[0019]
Next, a case will be described in which the operation unit 20 is inclined from θ 1 to θ 212 ) as shown in FIG. When the operation unit 20 is tilted up theta 2, further driving rod correspondingly 13 moves on relatively inclined guide plane 23. At this time, a sense of moderation is generated by the drive rod 13 climbing over the bulging portion of the guide slope 23. That is, since the guide slope 23 is formed so as to bulge, when the operation unit 20 is inclined, the slope of the portion of the guide slope 23 that contacts the drive rod 13 becomes shallower. As a result, the component of the drag applied by the drive rod 13 to the guide slope 23 in the direction along the guide slope 23 due to the restoring force of the coil spring 12 is reduced, and a necessary operating force is reduced during the course of the tilting operation, resulting in a sense of moderation. I do.
At this time, when the operator releases the operation knob 21, the operation unit 20 returns to the center position by the drive rod 13 urged upward by the restoring force of the coil spring 12. similar to that when tilted by theta 1.
[0020]
By operating portion 20 is inclined by theta 2 also moves further downward the upper end of the push rod 31 is pressed by the cover pressing face 24 of the cover portion 22, also moves to the lower body portion 33a. Further, when the main body 33a moves further downward, the deformable portion 33b buckles and deforms inward, whereby the deformable portion 33b generates a sense of moderation. That is, the deformed portion 33b generates deformation resistance when deformed, but when the main body 33a moves downward and the deformed portion 33b is deformed, the deformed portion 33b cannot withstand the pressing force and bends inward. (Buckles). When buckling, the deformation resistance is reduced, thereby generating a sense of moderation. Further, when the main body 33a moves further downward, the elastic contact 34 provided on the lower surface of the main body 33a comes into contact with the substrate contact 41 on the substrate 40, thereby creating a conductive state of the substrate 40.
Also, at this time, when the operator releases his / her hand from the operation knob 21, the operating portion 20 is moved to the center position via the cover pressing surface 24 by the push rod portion 31 urged upward by the restoring elastic force of the deformed portion 33b. the return is the same as when the operation unit 20 is tilted by theta 1.
[0021]
Such a sense of moderation by the guide slope 23 and the drive rod 13 and a sense of moderation by the deforming portion 33b are generated almost simultaneously. Specifically, the degree of bulging of the guide slope 23, the shape of the tip of the drive rod 13, the material and size of the coil spring 12, the material of the elastic body 33, the shape and thickness of the deformed portion 33b, and the like are adjusted. Thus, the timing at which the sense of moderation occurs can be adjusted.
As described above, by generating two kinds of moderation sensations almost simultaneously, it is possible to generate an unprecedented complex moderation sensation. Further, by changing the strength, material, and shape of the coil spring 12, and further changing the thickness, shape, and material of the deformed portion 33b, the sense of moderation generated can be freely changed by a combination thereof.
[0022]
The embodiments of the present invention have been described above. However, the present invention is not limited to the matters described in the above embodiment, and can be changed and improved based on the description in the claims. For example, in the above-described embodiment, the guide slope is formed in a bulging shape, and the drive rod crosses the bulge portion of the guide slope to generate a sense of moderation. However, the present invention is not limited to this. For example, it is possible to form a step that is sufficiently smaller than the drive rod on the guide slope and generate a sense of moderation by the drive rod climbing over this step. May be adopted.
[0023]
In the present embodiment, a coil spring is used. However, the member for urging the drive rod upward is not particularly limited to this, and may be any elastic member that generates a restoring force. However, in order to generate a different moderation feeling, it is desirable that the material is different from the elastic body.
Further, the operating section does not necessarily need to have such a shape, and may be, for example, a seesaw-like form instead of a form in which an operation knob is provided.
[0024]
【The invention's effect】
According to the present invention described above, by the operation swing of the operation unit, the pressing unit moves on the guide slope while being pressed downward by the guide slope to generate a sense of moderation, and the elastic body is pressed downward by the push rod unit. A moderation feeling is generated by buckling deformation while generating these moderation feelings almost simultaneously, so the moderation feeling due to the guide slope and the pressing part and the moderation feeling due to the buckling deformation of the elastic body are combined, It is possible to generate a sense of moderation. Further, these moderation feelings can be changed by deforming the shape, material, and the like, and the moderation feeling generated can be freely changed by a combination thereof.
Further, the restoring force for returning the operation unit to the center position is shared by the elastic member of the switch body and the elastic body of the contact portion, so that the operation unit is conventionally returned to the center position with only one restoring force. Compared with the case, the load applied to the elastic member or the elastic body is reduced, the life can be extended, and the size of the parts can be reduced. Further, the operation sound of the operation unit can be reduced.
[0025]
Further, according to the present invention, the guide slope is formed by bulging the respective surfaces facing each other in a substantially V-shape, and the pressing portion is pressed downward by the guide slope by the operation swing of the operation portion. Since the moderation is generated by climbing over the bulging portion, the moderation required for the operation switch can be easily generated.
[0026]
Further, according to the present invention, the elastic body of the contact portion includes a main body portion connected to the push rod portion and having an elastic body contact on a lower surface, and a thin deformed portion formed in a bell shape from a lower portion of the main body portion. The part is buckled and deformed inward with the movement of the main part pressed by the push rod part, and the elastic contact of the main part is brought into contact with the substrate contact, so the deformed part is bent inward and buckled and deformed. After the buckling deformation, the deformation resistance is reduced, and a moderation feeling can be generated. At the same time, an elastic contact provided on the lower surface of the main body can be brought into contact with the substrate contact to create a conductive state of the substrate.
[0027]
Further, according to the present invention, since the upper end portion of the push rod portion contacts the end of the operation portion in the initial state, the push rod portion is pressed by the operation portion even in a state where the inclination angle of the operation portion is small, and through the push rod portion. The elastic body deforms and generates deformation resistance. For this reason, no matter where the operating section is inclined, the resistance of the pressing section to the guide slope and the deformation resistance of the elastic body are generated, so that a unified operation feeling can be given.
