本発明の実施形態であるスイッチ装置を適用した車両用の計器装置を説明する。 An instrument device for a vehicle to which a switch device according to an embodiment of the present invention is applied will be described.

計器装置は、硬質な回路基板３と、この回路基板３の裏面側に回路基板３と導通状態で装着され、回路基板３を貫通して前方に延びる回動軸４を有する計器本体５と、回動軸４の先端側に固着された指針６と、車両の走行情報を表示する表示部Ｓを視認するための開口窓を有した表示板７と、この表示板７と回路基板３との間に配置され、表示板７を保持する白色の合成樹脂からなるケース体８と、回路基板３上に実装され指針６や表示板７を背後から照明する光源としての発光ダイオード９と、回路基板３の裏面側を覆うカバー１０と、表示板７の前方側に配置され表示板７の可視領域を定めるリング部材１２と、指針６や表示板７などの前方側を被う無色透明の前面カバー１３を備えている。 The instrument device includes a rigid circuit board 3, an instrument body 5 having a rotating shaft 4 which is mounted on the back surface side of the circuit board 3 in a conductive state with the circuit board 3, and extends forward through the circuit board 3. A pointer 6 fixed to the tip end side of the rotating shaft 4, a display board 7 having an opening window for visually recognizing a display section S for displaying the traveling information of the vehicle, the display board 7 and the circuit board 3. A case body 8 made of white synthetic resin, which is arranged between the two and holds the display board 7, a light emitting diode 9 as a light source mounted on the circuit board 3 to illuminate the pointer 6 and the display board 7 from behind, and a circuit board. 3, a cover 10 that covers the back side of the display plate 3, a ring member 12 that is disposed on the front side of the display plate 7 and defines the visible region of the display plate 7, and a colorless and transparent front cover that covers the front side of the pointer 6, the display plate 7, and the like. Equipped with 13.

表示板７には、後述する操作部材１８を貫通させ、順次組み付け可能とするための貫通孔７ａが設けられている。また、表示板７には、その他の貫通孔として、表示板７を一方向へスライドさせてケース体と係合させる凹部（図示せず）が設けられている。 The display plate 7 is provided with a through hole 7a for allowing an operation member 18 described later to penetrate therethrough and enabling sequential assembly. Further, the display plate 7 is provided with a recess (not shown) as another through hole that slides the display plate 7 in one direction to engage with the case body.

前面カバー１３には、後述する操作部材１８を貫通させ、順次組み付け可能とするための貫通孔１３ａが設けられている。 The front cover 13 is provided with a through hole 13a through which an operation member 18, which will be described later, penetrates and can be sequentially assembled.

また、計器装置は車両の走行情報を表示する表示部Ｓと、その表示部Ｓの輝度を調節する、例えばイルミネーションコントロールからなるスイッチ装置１を備えている。 In addition, the instrument device includes a display unit S that displays traveling information of the vehicle, and a switch device 1 that adjusts the brightness of the display unit S and that includes, for example, an illumination control.

スイッチ装置１は、回路基板３に半田付け固定された可動部１７ａを有するスイッチ１７と、このスイッチ１７が配置される硬質な回路基板３と、スイッチ１７を押圧操作する合成樹脂製の操作部材１８とを備えている。回路基板３は、速度計や回転計の計器本体５が装着された基板である。また、本実施形態におけるスイッチ装置１は、前面カバー１３に設けられた貫通孔１３ａから操作部材１８が貫通する構造となっている。 The switch device 1 includes a switch 17 having a movable portion 17a fixed to the circuit board 3 by soldering, a hard circuit board 3 on which the switch 17 is arranged, and an operating member 18 made of synthetic resin for pressing the switch 17. It has and. The circuit board 3 is a board on which an instrument main body 5 such as a speedometer or a tachometer is mounted. Further, the switch device 1 according to the present embodiment has a structure in which the operation member 18 penetrates through the through hole 13a provided in the front cover 13.

ケース体８は、表示板７を背面側から保持する。ケース体８は、表示板７の貫通孔７ａの凹部に係合される係合フック（図示せず）を有しており、スライド方向の凹部と係合することで表示板７を保持している。 The case body 8 holds the display plate 7 from the back side. The case body 8 has an engaging hook (not shown) which is engaged with the recess of the through hole 7a of the display plate 7, and holds the display plate 7 by engaging with the recess in the sliding direction. There is.

また、ケース体８は、表示板７をほぼ水平に保持するための天面部８ａと、その天面部８ａから回路基板３へ向かって延設された脚部８ｂと、操作部材１８の後述する突出部に向かって一定の距離が離れた状態で脚部８ｂから突出形成された壁部８ｃとを有している。本実施形態の場合、一定の距離が離れた状態とは、操作部材１８が傾いた際に突出部が壁部８ｃと接触する程度の距離を示している。 Further, the case body 8 has a top surface portion 8a for holding the display plate 7 substantially horizontally, a leg portion 8b extending from the top surface portion 8a toward the circuit board 3, and a protrusion of the operation member 18 which will be described later. The wall portion 8c is formed so as to project from the leg portion 8b with a certain distance away from the leg portion. In the case of the present embodiment, the state in which a certain distance is separated indicates a distance at which the protrusion contacts the wall portion 8c when the operation member 18 is tilted.

壁部８ｃは、図３に示すように、操作部材１８が傾いた状態で配置された場合に、操作部材１８の外周壁面が表示板７に当接して表示板７を操作部材１８の傾く方向へ押してしまい、例えば、フック係合が外れてしまうなどの不具合を防ぐために形成されたものである。 As shown in FIG. 3, when the operation member 18 is disposed in a tilted state, the wall portion 8c is in a direction in which the outer peripheral wall surface of the operation member 18 contacts the display plate 7 and the display plate 7 is inclined. It is formed in order to prevent a problem such as pushing the hook to disengage the hook.

操作部材１８は、スイッチ１７を押圧する突出部である押圧部１８ｂが一体形成されたノブ１８ａを備えている。 The operation member 18 includes a knob 18a integrally formed with a pressing portion 18b that is a protruding portion that presses the switch 17.

ノブ１８ａは、合成樹脂から形成され、スイッチ１７の可動部１７ａ上に当接し、可動部１７ａを押圧する板状の押圧部１８ｂを有している。 The knob 18a is made of synthetic resin, and has a plate-shaped pressing portion 18b that abuts on the movable portion 17a of the switch 17 and presses the movable portion 17a.

押圧部１８ｂと表示板７との間には、光源９の光が貫通孔１３ａから漏れるのを防止するために、樹脂やゴムなどからなるパッキン１８ｃが装着されている。 A packing 18c made of resin, rubber or the like is mounted between the pressing portion 18b and the display plate 7 in order to prevent light from the light source 9 from leaking from the through hole 13a.

スイッチ装置１の組み付け方法を説明する。スイッチ１７は、半田付けなどの工程によって回路基板３に組み付けられている。スイッチ１７の可動部１７ａと押圧部１８ｂとが当接するように配置させたのち、表示板７に設けられた貫通孔７ａに貫通させる。このとき、操作部材１８が傾いて配置されたとしても、突出部（押圧部１８ｂ）が壁部８ｃと当接することで傾きすぎることがないので、ノブ１８ａが貫通孔７ａの内壁と接触してしまっても、表示板７が操作部材１８の傾く方向へ動くことを防ぐ。その後、操作部材１８は、前面カバー１３の貫通孔１３ａに貫通される。 A method of assembling the switch device 1 will be described. The switch 17 is assembled to the circuit board 3 by a process such as soldering. The switch 17 is arranged so that the movable portion 17a and the pressing portion 18b are in contact with each other, and then the switch 17 is penetrated into the through hole 7a provided in the display plate 7. At this time, even if the operating member 18 is arranged to be inclined, the protrusion (pressing portion 18b) does not tilt too much due to contact with the wall portion 8c, so that the knob 18a comes into contact with the inner wall of the through hole 7a. Even if it does, the display plate 7 is prevented from moving in the direction in which the operating member 18 is tilted. Then, the operation member 18 is penetrated through the through hole 13 a of the front cover 13.

このように本発明は、表示板７と、表示板７を保持するケース体８と、可動部１７ａを有するスイッチ１７と、このスイッチ１７の前方側に配置される操作部材１８と、を備えたスイッチ装置１において、操作部材１８は、スイッチ１７の前方に配置され操作部材１８が貫通する貫通孔７ａを備えた表示板７の背後側に延設された押圧部１８ｂを有し、ケース体８は、操作部材１８が傾いた場合に突出部１８ｂと当接する位置に壁部８ｃを備えたことによって、操作部材１８が傾いた場合に操作部材１８の一部と壁部８ｃとが当接するので、表示板７が操作部材１８の傾く方向へ動くことを防止することができる。 As described above, the present invention includes the display plate 7, the case body 8 that holds the display plate 7, the switch 17 having the movable portion 17a, and the operation member 18 arranged on the front side of the switch 17. In the switch device 1, the operation member 18 has a pressing portion 18b that is disposed in front of the switch 17 and that is extended to the rear side of the display plate 7 having a through hole 7a through which the operation member 18 penetrates. Since the wall portion 8c is provided at a position where the operating member 18 contacts the protruding portion 18b when the operating member 18 tilts, a part of the operating member 18 and the wall portion 8c contact when the operating member 18 tilts. The display plate 7 can be prevented from moving in the direction in which the operation member 18 is inclined.

なお、本実施形態では、壁部８ｃと当接する突出部１８ｂを、押圧部１８ｂとしていたが、表示板７が操作部材１８の傾く方向へ動かないように壁部８ｃと操作部材１８の一部が当接するならば、その部位は押圧部１８ｂに限定されず、その形状は任意である。 In the present embodiment, the protruding portion 18b that comes into contact with the wall portion 8c is the pressing portion 18b. However, the shape is not limited to the pressing portion 18b as long as they contact each other.
