Description

本発明は、オーディオやヒーター等の各種車載機器の操作を受け付ける為の押しボタン式のスイッチノブの取付構造に関する。   The present invention relates to a push button switch knob mounting structure for receiving operations of various in-vehicle devices such as audio and heaters.

各種車載機器の操作を受け付ける為のスイッチノブの配置されるスイッチパネルの中には、夜間の操作性の向上を図るべく、スイッチノブの周囲にスイッチノブを照明する為の照明用導光部材が配設されたものが提案されている。その種の従来のスイッチパネル１００では、例えば図１及び図３の様に、照明用導光部材１０７は、パネル基板１０３の所定部位に配設されており、スイッチノブ１０５は、そのスイッチノブ１０５に設けられた支持部１０５ｂを介してパネル基板１０３に取り付けられる事により、照明用導光部材１０７に対し適宜間隔ｄを開けてパネル基板１０３に配置される。   In the switch panel where switch knobs for accepting operations of various in-vehicle devices are arranged, there is a light guide member for illuminating the switch knob around the switch knob in order to improve the operability at night. Arrangements have been proposed. In such a conventional switch panel 100, for example, as shown in FIGS. 1 and 3, the light guide member 107 for illumination is disposed at a predetermined portion of the panel substrate 103, and the switch knob 105 is the switch knob 105. By being attached to the panel substrate 103 via the support portion 105 b provided on the light guide member 107, the light guide member 107 for illumination is arranged on the panel substrate 103 with an appropriate interval d.

従来のスイッチパネル１００では、スイッチノブ１０５がパネル基板１０３に取り付けられる為、各スイッチノブ１０５と照明用導光部材１０７との間隔ｄは、スイッチノブ１０５とパネル基板１０３との間の組み付けばらつきと、パネル基板１０３と照明用導光部材１０７との間の組み付けばらつきとの双方の影響を受けて大きくばらつき、その結果、意匠的に見栄えが悪くなり、場合によってはスイッチノブ１０５と照明用導光部材１０７が干渉して操作に不具合が生じる虞があるという問題がある。   In the conventional switch panel 100, since the switch knob 105 is attached to the panel substrate 103, the distance d between each switch knob 105 and the light guide member 107 for illumination is a variation in assembly between the switch knob 105 and the panel substrate 103. In this case, there is a large variation under the influence of both the assembly variation between the panel substrate 103 and the illumination light guide member 107. As a result, the design looks bad, and in some cases, the switch knob 105 and the illumination light guide There is a problem that the member 107 may interfere with the operation to cause a malfunction.

そこで、この発明の課題は、スイッチノブと照明用導光部材との隙間のばらつきを低減できて意匠性及び操作性を向上できるスイッチノブの取付構造を提供することにある。   Accordingly, an object of the present invention is to provide a switch knob mounting structure that can reduce the variation in the gap between the switch knob and the light guide member for illumination and can improve the design and operability.

上記課題を解決する為には、請求項１に記載の発明は、パネル基板に配設された照明用導光部材に対し適宜間隔を保って前記パネル基板に配置される押しボタン式のスイッチノブの取付構造であって、前記スイッチノブは、可撓性部材により形成された支持部を有し、前記支持部を介して直接に前記照明用導光部材に取り付けられて前記パネル基板に配置され、前記照明用導光部材は、前記パネル基板の後面上に配置される導光部と、前記パネル基板に設けられた開口部の内周面上に配置される光射出部と、前記導光部の後面において前記光射出部よりも外周側に形成された前記取付部とを有し、前記スイッチノブは、前記照明用導光部材の前記光射出部に対し適宜間隔を保って前記パネル基板の前記開口部内に配置されるスイッチノブ本体と、前記スイッチノブ本体を前記照明用導光部材の前記取付部に押込操作に応じて復帰自在に後退できる様に固定支持する前記支持部とを有し、所定の光源からの光が前記導光部内を伝達して前記光射出部から照明光として射出されるものである。 In order to solve the above-mentioned problems, the invention according to claim 1 is a push button type switch knob arranged on the panel substrate at an appropriate interval with respect to the light guide member for illumination arranged on the panel substrate. The switch knob has a support portion formed of a flexible member, and is directly attached to the illumination light guide member via the support portion and disposed on the panel substrate. The light guide member for illumination includes a light guide portion disposed on a rear surface of the panel substrate, a light emitting portion disposed on an inner peripheral surface of an opening provided in the panel substrate, and the light guide.

図１は本発明のスイッチノブ取付構造が適用されたスイッチパネルの正面図の一例図であり、図２は図１のII-II断面図である。   FIG. 1 is an example of a front view of a switch panel to which the switch knob mounting structure of the present invention is applied, and FIG. 2 is a sectional view taken along line II-II in FIG.

この実施の形態のスイッチパネル１は、オーディオやヒーター等の各種車載機器の操作を受け付ける為のスイッチノブが配置されるものであり、図１及び図２の様に、パネル基板３と、パネル基板３に設けられた開口部３ａ内に配置された押しボタン用のスイッチノブ５と、パネル基板３に於けるスイッチノブ５の周囲に配設されて、所定の光源からの光を導光してスイッチノブ用の照明光としてスイッチノブ５の周囲から射出する導光レンズ（照明用導光部材）７と、パネル基板３の後面側に配設されて、スイッチノブ５の押込操作に応じてオンオフされるタクトスイッチ（図示省略）や導光レンズ７に照明用の光を供給する光源（図示省略）が実装された回路基板（図示省略）とを備えて主構成される。   The switch panel 1 of this embodiment is provided with a switch knob for receiving operations of various in-vehicle devices such as audio and heaters. As shown in FIGS. 1 and 2, the panel substrate 3 and the panel substrate The switch knob 5 for the push button disposed in the opening 3a provided in the position 3 and the switch knob 5 on the panel substrate 3 are arranged around the switch knob 5 to guide light from a predetermined light source. A light guide lens (light guide member for illumination) 7 emitted from the periphery of the switch knob 5 as illumination light for the switch knob and a rear surface side of the panel substrate 3 are turned on / off in response to the pushing operation of the switch knob 5. And a circuit board (not shown) on which a light source (not shown) for supplying illumination light to the light guide lens 7 is mounted.

尚、このスイッチパネル１には、ダイヤル式のスイッチノブ６も備えられているが、本発明と関係無いのでこれ以上の説明は省略する。   The switch panel 1 is also provided with a dial type switch knob 6. However, since it is not related to the present invention, further explanation is omitted.

ここでは、各スイッチノブ５は横一列に隣接配置されており、これに応じてパネル基板３の開口部３ａは横長矩形状に形成されている。   Here, the switch knobs 5 are arranged adjacent to each other in a horizontal row, and the opening 3a of the panel substrate 3 is formed in a horizontally long rectangular shape accordingly.

導光レンズ７は、例えば図２の様に、パネル基板３の開口部３ａより一回り大きい寸法の例えば板状の導光部７ａを有し、その導光部７ａの略中央には、各スイッチノブ５が配置される例えば横長矩形状の開口部７ｂが形成され、その導光部７ａの前面上の開口部７ｂの周縁には、その周縁に亘り照明光が射出される光射出部７ｃが突条形成され、その導光部７ａの後面には、各スイッチノブ５が取り付けられる例えば凸状の取付部７ｄと前記回路基板に実装された光源からの光を入射する光入射部（図示省略）とが形成されて成る。この導光レンズ７は、その導光部７ａの前面がパネル基板３の後面上に配置され、且つその光射出部７ｃがパネル基板３の開口部３ａの内周面に嵌合される様にしてパネル基板３に取り付けられる。   The light guide lens 7 has, for example, a plate-shaped light guide portion 7a having a size slightly larger than the opening 3a of the panel substrate 3 as shown in FIG. 2, for example. For example, a horizontally-long rectangular opening 7b in which the switch knob 5 is disposed is formed, and a light emitting portion 7c from which illumination light is emitted over the periphery of the opening 7b on the front surface of the light guide portion 7a. Is formed on the rear surface of the light guide portion 7a, for example, a convex attachment portion 7d to which each switch knob 5 is attached, and a light incident portion (illustrated) for receiving light from a light source mounted on the circuit board. (Omitted) is formed. The light guide lens 7 is configured such that the front surface of the light guide portion 7 a is disposed on the rear surface of the panel substrate 3 and the light emitting portion 7 c is fitted to the inner peripheral surface of the opening 3 a of the panel substrate 3. To the panel substrate 3.

尚、この導光レンズ７では、前記光入射部に入射された前記光源からの光は、導光部７ａ内を伝搬して光射出部７ｃの前端面７ｅから照明光として射出され、これによりスイッチノブ５の操作面５ｄが照明される。   In this light guide lens 7, the light from the light source incident on the light incident part propagates through the light guide part 7a and is emitted as illumination light from the front end surface 7e of the light emitting part 7c. The operation surface 5d of the switch knob 5 is illuminated.

各スイッチノブ５は、可撓性部材により、例えば略直方体状で後面開放の箱状に形成されたスイッチノブ本体５ａと、押込操作に応じてスイッチノブ本体５ａが弾性復帰自在に後退する様にスイッチノブ本体５ａを導光レンズ７の取付部７ｄに固定支持する支持部５ｂとを有して形成される。   Each switch knob 5 is made of a flexible member, for example, a switch knob body 5a formed in a box shape having a substantially rectangular parallelepiped shape and an open rear surface, and the switch knob body 5a is retracted so as to be elastically reversible in response to a pushing operation. The switch knob body 5a is formed to have a support portion 5b for fixing and supporting the switch knob body 5a to the mounting portion 7d of the light guide lens 7.

支持部５ｂは、例えば、スイッチノブ本体５ａの側面（ここでは上側側面）の後縁部から立設されて前方に屈曲された支持部本体５ｂ−１と、導光レンズ７の取付部７ｄに固着（ここでは嵌着）された例えば筒状の固定部５ｂ−２と、ヒンジ変形可能な様に薄肉状に形成されて支持部本体５ｂ−１と固定部５ｂ−２とをヒンジ結合するヒンジ部５ｂ−３とを有して形成される。即ち、スイッチノブ本体５ａへの押込操作に対してヒンジ部５ｂ−３が弾性復帰自在にヒンジ変形する事によりスイッチノブ本体５ａが弾性復帰自在に後退される。   The support portion 5b is formed, for example, on a support portion main body 5b-1 that is erected from the rear edge portion of the side surface (here, the upper side surface) of the switch knob main body 5a and bent forward, and on the attachment portion 7d of the light guide lens 7. For example, a cylindrical fixing portion 5b-2 that is fixed (here, fitted), and a hinge that is formed in a thin shape so that the hinge can be deformed and hinges the support portion main body 5b-1 and the fixing portion 5b-2. Part 5b-3. That is, the switch knob body 5a is retracted elastically when the hinge portion 5b-3 is hinged to be elastically restored in response to the pushing operation to the switch knob body 5a.

これらのスイッチノブ５は、その操作面５ｄがパネル基板３の開口部３ａから露出する様にそのスイッチノブ本体５ａが導光レンズ７の開口部７ｂ内に配置された状態で、その固定部５ｂ−２が導光レンズ７の取付部７ｄに固着される事により、導光レンズ７に取り付けられる。この取付状態では、各スイッチノブ本体５ａと導光レンズ７の光射出部７ｃとの間隔ｄは、均一な適宜間隔に保たれる。   These switch knobs 5 have their fixing portions 5b in a state in which the switch knob body 5a is disposed in the opening 7b of the light guide lens 7 so that the operation surface 5d is exposed from the opening 3a of the panel substrate 3. -2 is fixed to the light guide lens 7 by being fixed to the attachment portion 7d of the light guide lens 7. In this attached state, the distance d between each switch knob body 5a and the light emitting portion 7c of the light guide lens 7 is kept at a uniform appropriate distance.

以上に説明したスイッチノブ５の取付構造によれば、スイッチノブ５は、そのスイッチノブ５に設けられた支持部５ｂを介して直接に導光レンズ７に取り付けられる為、即ち従来の様にパネル基板３を介して導光レンズ７に取り付けられない為、スイッチノブ５と導光レンズ７との隙間ｄのばらつきを低減でき、これにより見栄えを良くできて意匠性を向上できると共にスイッチノブ５と導光レンズ７との干渉を防止できて操作性を向上できる。   According to the mounting structure of the switch knob 5 described above, the switch knob 5 is directly mounted on the light guide lens 7 via the support portion 5b provided on the switch knob 5, that is, as in the conventional panel. Since it cannot be attached to the light guide lens 7 via the substrate 3, it is possible to reduce the variation in the gap d between the switch knob 5 and the light guide lens 7, thereby improving the appearance and improving the design and the switch knob 5. Interference with the light guide lens 7 can be prevented and operability can be improved.

又、導光レンズ７は、パネル基板３の後面上に配置される導光部７ａと、パネル基板３に設けられた開口部３ａの内周面上に配置される光射出部７ｃとを有して形成され、スイッチノブ５が、導光レンズ７の光射出部７ｃに対し適宜間隔ｄを保ってパネル基板３の開口部３ａ内に配置されるスイッチノブ本体５ａと、このスイッチノブ本体５ａを導光レンズ７の導光部７ａに押込操作に応じて復帰自在に後退できる様に固定支持する支持部５ｂとを有して形成される為、簡単な構成でスイッチノブ５を押込操作に応じて復帰自在に後退できる様に導光レンズ７に取り付けられる。   The light guide lens 7 includes a light guide portion 7 a disposed on the rear surface of the panel substrate 3 and a light emitting portion 7 c disposed on the inner peripheral surface of the opening 3 a provided in the panel substrate 3. The switch knob body 5a is formed in the opening 3a of the panel substrate 3 with an appropriate distance d from the light emitting portion 7c of the light guide lens 7, and the switch knob body 5a. Is formed on the light guide portion 7a of the light guide lens 7 with a support portion 5b that is fixedly supported so that it can be retracted back in response to the push operation, so that the switch knob 5 can be pushed with a simple configuration. Accordingly, it is attached to the light guide lens 7 so as to be able to retreat freely.
