以下、本発明に係る車両用表示装置を車両のコンビネーションメータに適用する最良の形態を、図１乃至図３の図面を参照して説明する。なお、従来の技術のところで説明したものと同一あるいは相当する部分には同一符号を付してその詳細な説明は省略する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode of applying a vehicle display device according to the present invention to a vehicle combination meter will be described below with reference to the drawings of FIGS. In addition, the same code | symbol is attached | subjected to the part which is the same as that of what was demonstrated in the prior art, or the detailed description is abbreviate | omitted.

図１に示すコンビネーションメータ１は、速度計Ａ、回転計Ｂとしての複数（図１中では２つ）の車両用表示装置１０と、２つの車両用表示装置１０の縁部を覆う見返し４と、を有している。そして、コンビネーションメータ１は、それらをケース５内に収容して図示しない表ガラスで覆った状態で車両に搭載される。なお、コンビネーションメータ１は、水温計、燃料計等の他の計器を車両用表示装置１０として追加することもできる。   A combination meter 1 shown in FIG. 1 includes a plurality of (two in FIG. 1) vehicle display devices 10 as a speedometer A and a tachometer B, and a turnover 4 that covers the edges of the two vehicle display devices 10. ,have. And the combination meter 1 is mounted in a vehicle in the state which accommodated them in the case 5 and covered with the surface glass which is not shown in figure. In addition, the combination meter 1 can also add other gauges, such as a water temperature gauge and a fuel gauge, as the display apparatus 10 for vehicles.

また、前記表ガラスは、透過率の低いスモークパネル等の着色透光性部材で形成されている。前記表ガラスは、文字板１１の指標部１１ｂを透過した光を透過して利用者に向けて出射する。つまり、光源１５が光輝したときに指標部１１ｂを視認可能とし且つ光源１５が光輝しないときは視認を阻止する実施形態の場合について説明するが、本発明は、透明な表ガラスを用いることもできる。   Moreover, the said surface glass is formed with colored translucent members, such as a smoke panel with low transmittance | permeability. The said front glass permeate | transmits the light which permeate | transmitted the parameter | index part 11b of the dial plate 11, and radiate | emits it toward a user. That is, the case of an embodiment in which the indicator portion 11b is visible when the light source 15 shines and the visual recognition is blocked when the light source 15 does not shine will be described. However, the present invention can also use a transparent front glass. .

次に、本発明の車両用表示装置１０を速度計Ａの場合の構成について以下に説明する。なお、回転計Ｂの車両用表示装置１０の説明は、基本構成が速度計Ａと同一であることから説明を省略する。   Next, the configuration of the vehicle display device 10 of the present invention in the case of the speedometer A will be described below. The description of the vehicle display device 10 of the tachometer B is omitted because the basic configuration is the same as that of the speedometer A.

車両用表示装置１０は、図２及び図３に示すように、文字板１１と、この文字板１１の前面側に配置される指針１２と、計測量に応じて指針１２を駆動する内機１３と、回路パターンが設けられ内機１３が固定される配線板１４と、配線板１４に設けられた複数の光源１５と、ケース５から配線板１４に向かって設けられて光源１５の光を反射するテーパ状の反射部材１６と、裏カバー１７（図５参照）と、装飾リング１８と、文字板１１の前面側に配置される立体指標２０と、この立体指標２０を光輝させる立体指標用光源３０と、を有している。   As shown in FIGS. 2 and 3, the vehicular display device 10 includes a dial plate 11, a pointer 12 disposed on the front side of the dial plate 11, and an internal unit 13 that drives the pointer 12 according to a measurement amount. A wiring board 14 on which a circuit pattern is provided and the internal unit 13 is fixed; a plurality of light sources 15 provided on the wiring board 14; and a light source 15 reflected from the case 5 toward the wiring board 14 A tapered reflecting member 16, a back cover 17 (see FIG. 5), a decorative ring 18, a three-dimensional index 20 arranged on the front side of the dial 11, and a three-dimensional index light source for illuminating the three-dimensional index 20. 30.

文字板１１は、例えば、ポリカーボネイト等の透光性の合成樹脂で各メータに対応した略円形板状に形成された文字板生地１１ａと、文字板生地１１ａの前面に設けられた指標部１１ｂと、この指標１１ｂ以外の文字板生地１１ａの前面に設けられた遮光部１１ｃと、を有している。   The dial 11 is made of, for example, a dial cloth 11a formed of a translucent synthetic resin such as polycarbonate in a substantially circular plate shape corresponding to each meter, and an indicator portion 11b provided on the front surface of the dial cloth 11a. And a light shielding portion 11c provided on the front surface of the dial fabric 11a other than the indicator 11b.

文字板生地１１ａは、光源１５からの光を文字板１１の前面に向けて透過する。指標部１１ｂは、図１に示すように、速度計Ａに対応した「０〜１８０」の数字と「ｋｍ／ｈ」の文字等の意匠が透光性部材の印刷によって形成されている。遮光部１１ｃは、黒色等の非透光性部材の印刷によって形成されている。このように文字板１１を構成することで、光源１５が光輝すると、その光が文字板生地１１ａを透過して指標部１１ｂから観測者方向に出射されるため、観測者は指標部１１ｂを発光しているように視認する。   The dial fabric 11 a transmits light from the light source 15 toward the front surface of the dial 11. As shown in FIG. 1, the indicator portion 11 b is formed with a design such as numbers “0 to 180” and characters “km / h” corresponding to the speedometer A by printing a translucent member. The light shielding part 11c is formed by printing a non-translucent member such as black. By configuring the dial 11 in this manner, when the light source 15 shines, the light passes through the dial cloth 11a and is emitted from the indicator portion 11b toward the observer, so that the observer emits the indicator portion 11b. Visually as if it were.

指針１２は、周知であるように、指示部１２ａと基部とからなる指針本体と、該基部を覆う黒色等の不透明な樹脂材料から成る指針キャップ１２ｂと、を有している。指針本体は、指針袴を介して内機１３に固着されることで、駆動軸によって回動される。指針本体は、透明なアクリル樹脂で形成されており、その内部を光源１５からの光を導光することで、指示部１２ａを発光させている。   As is well known, the pointer 12 includes a pointer main body including an instruction portion 12a and a base portion, and a pointer cap 12b made of an opaque resin material such as black covering the base portion. The pointer body is rotated by the drive shaft by being fixed to the inner unit 13 via the pointer rod. The pointer main body is formed of a transparent acrylic resin, and guides the light from the light source 15 in the interior thereof, thereby causing the instruction unit 12a to emit light.

内機１３は、周知であるステッパモータ、クロスコイルムーブメント等が用いられ、計測量に応じて指針１２を駆動する。光源１５は、ＬＥＤ、バルブ等が用いられ、配線板１４に実装されて図示しない制御部によって点灯、消灯が制御される。   As the internal unit 13, a well-known stepper motor, cross coil movement, or the like is used, and the pointer 12 is driven according to the measurement amount. The light source 15 uses an LED, a bulb, and the like. The light source 15 is mounted on the wiring board 14 and controlled to be turned on and off by a control unit (not shown).

反射部材１６は、合成樹脂等によってテーパ状に形成されており、その表面には反射率を向上させる反射面が形成されている。裏カバー１７は、配線板１４の背後等を覆うようにケース５に組み付けられる。   The reflecting member 16 is formed in a tapered shape with a synthetic resin or the like, and a reflecting surface for improving the reflectance is formed on the surface thereof. The back cover 17 is assembled to the case 5 so as to cover the back of the wiring board 14 and the like.

装飾リング１８は、観測者から目盛部２１のみが目視可能なように立体指標２０を覆うカバー部に相当している。装飾リング１８は、非透光性部材によってリング状に形成されており、観測者から目盛部２１のみが目視可能なように立体指標２０を覆っている。なお、本最良の形態では、装飾リング１８をカバー部とする場合について説明するが、見返し４等の他の遮光部材で実現することもできる。また、装飾リング１８については、透光性部材によって形成するなど製品仕様等に応じて任意に設計することができる。   The decorative ring 18 corresponds to a cover portion that covers the three-dimensional index 20 so that only the scale portion 21 is visible to the observer. The decorative ring 18 is formed in a ring shape by a non-translucent member, and covers the three-dimensional index 20 so that only the scale portion 21 can be seen by an observer. In the best mode, the case where the decorative ring 18 is used as a cover will be described. Further, the decorative ring 18 can be arbitrarily designed according to product specifications, such as being formed of a translucent member.

立体指標２０は、図２及び図３に示すように、複数の目盛部２１と、複数の受光部２２と、複数の連結部２３と、嵌合部２４と、を有し、それらはアクリル樹脂、ポリカーボネート等の導光性樹脂部材によって一体に形成されている。   As shown in FIGS. 2 and 3, the three-dimensional index 20 includes a plurality of scale parts 21, a plurality of light receiving parts 22, a plurality of connecting parts 23, and a fitting part 24, which are acrylic resins. The light guide resin member such as polycarbonate is integrally formed.

目盛部２１は、車両の速度状態の目印となる目盛に相当しており、文字板１１の指標部１１ｂに対する第１目盛２１ａと、該第１目盛２１ａよりも小さな第２目盛２１ｂと、を有している。なお、第１目盛２１ａと第２目盛２１ｂの基本構成は同一となっている。   The scale portion 21 corresponds to a scale that serves as a mark for the speed state of the vehicle, and has a first scale 21a for the indicator portion 11b of the dial 11 and a second scale 21b that is smaller than the first scale 21a. is doing. The basic configuration of the first scale 21a and the second scale 21b is the same.

目盛部２１は、先端に行くにしたがって細くなるように略直方体として形成されている。つまり、目盛部２１の先端部は略針状に形成されている。なお、目盛部２１の形状については、単なる直方体、略円錐形、略弾丸形など種々異なる形状とすることもできる。   The scale part 21 is formed as a substantially rectangular parallelepiped so as to become thinner as it goes to the tip. That is, the tip portion of the scale portion 21 is formed in a substantially needle shape. In addition, about the shape of the scale part 21, it can also be set as various different shapes, such as a simple rectangular parallelepiped, a substantially cone shape, and a substantially bullet shape.

目盛部２１は、その先端寄りの裏面から文字板１１の表面に向かって突出する段差部２１１を有しており、段差部２１１は文字板１１の表面に当接している。つまり、この段差部２１１の高さに相当する目盛部２１の裏面と文字板１１の表面との間に隙間Ｇを形成している。このように隙間Ｇを形成することで、目盛部２１の立体感を強調することができる。さらに、目盛部２１は、その上面に断面略三角形の凸部２１２を形成しており、立体感をより強調し且つ目盛部２１に高級感を持たせることができる。   The scale portion 21 has a step portion 211 that protrudes from the back surface near the tip toward the surface of the dial plate 11, and the step portion 211 is in contact with the surface of the dial plate 11. That is, a gap G is formed between the back surface of the scale portion 21 corresponding to the height of the step portion 211 and the front surface of the dial plate 11. By forming the gap G in this way, the stereoscopic effect of the scale portion 21 can be emphasized. Further, the scale portion 21 has a convex portion 212 having a substantially triangular cross section on the upper surface thereof, so that the three-dimensional effect can be further emphasized and the scale portion 21 can have a high-class feeling.

なお、目盛部２１に段差部２１１を形成せずに文字板１１から目盛部２１を浮かせる構成とすることもできるが、本実施形態のように段差部２１１を設けることで、段差部２１１によって目盛部２１を文字板１１に当接させた状態とすることができるため、目盛部２１の強度を確保し且つ熱による歪みの発生等を防止することができる。また、目盛部２１の文字板１１に対する擦れがなくなるため、表示品位の向上を図ることができる。   Although the scale portion 21 can be lifted from the dial 11 without forming the step portion 211 on the scale portion 21, the step portion 211 is provided with the step portion 211 as in the present embodiment so that the scale portion 21 can be scaled. Since the portion 21 can be brought into contact with the dial plate 11, the strength of the scale portion 21 can be secured and the occurrence of distortion due to heat can be prevented. Further, since the scale portion 21 is not rubbed against the dial plate 11, the display quality can be improved.

目盛部２１は、図３及び図４に示すように、その先端に形成され且つ目盛部２１内を導光した光Ｌ１を観測者方向（図中上方向）に反射する反射面２１３を有している。目盛部２１内を先端に向かって導光した光Ｌ１は反射面２１３で観測者方向に反射するので、目盛部２１の先端部を強く光らせることができるため、より一層斬新且つ美的な表示表現とすることができる。   As shown in FIGS. 3 and 4, the scale part 21 has a reflecting surface 213 that reflects light L <b> 1 formed at the tip thereof and guided through the scale part 21 in the observer direction (upward in the figure). ing.

And a plurality of (two in FIG. 3) sub-reflection surfaces 22d.

このように構成した受光部２２は、受光面２２ｂから受光部本体２２ａ内に光を受光すると、その光は受光部本体２２ａ内を他端側に向かって導光される。そして、図５に示すように、導光した光Ｌ３の一部は、反射面２２ｃで一方の副反射面２２ｄに向かって反射され、その副反射面２２ｄで目盛部２１方向に向かって反射されて連結部２３内を導光される。   When the light receiving unit 22 configured as described above receives light from the light receiving surface 22b into the light receiving unit main body 22a, the light is guided in the light receiving unit main body 22a toward the other end side. Then, as shown in FIG. 5, a part of the guided light L3 is reflected by the reflecting surface 22c toward the one sub-reflecting surface 22d, and reflected by the sub-reflecting surface 22d toward the scale portion 21. Then, the inside of the connecting portion 23 is guided.

連結部２３は、複数の目盛部２１と複数の受光部２２とを連結するように略リング状に形成されている。連結部２３は、文字板１１の外周に沿って配置されると、複数の目盛部２１の各々を文字板１１の表面上の所定位置に位置付ける。そして、受光部２２からの光を複数の目盛部２１の各々に向けて導光する。   The connecting portion 23 is formed in a substantially ring shape so as to connect the plurality of scale portions 21 and the plurality of light receiving portions 22. When the connecting portion 23 is arranged along the outer periphery of the dial 11, each of the plurality of scale portions 21 is positioned at a predetermined position on the surface of the dial 11. Then, the light from the light receiving unit 22 is guided toward each of the plurality of scale units 21.

嵌合部２４は、反射部材１６に凸状に形成された取付部１６ａに嵌合する溝状に形成されている。また、嵌合部２４は、図示していない位置決め部を有しており、複数の目盛部２１が所定位置に配置されるようになっている。そして、嵌合部２４が取付部１６ａに嵌合されることで、立体指標２０は反射部材１６に装着される。   The fitting portion 24 is formed in a groove shape that fits into a mounting portion 16 a formed in a convex shape on the reflecting member 16. Moreover, the fitting part 24 has the positioning part which is not shown in figure, and the some scale part 21 is arrange | positioned in a predetermined position. Then, the three-dimensional index 20 is attached to the reflecting member 16 by fitting the fitting portion 24 to the attachment portion 16a.

The light is reflected, and the light is guided in the connecting portion 23 toward each solid index 20. Then, the light is guided through the scale portion 21 toward the tip, and a part of the light irregularly reflected by the irregular reflection portion 214 is emitted from the convex portion 212 toward the observer. Therefore, the observer visually recognizes the scale portion 21 to emit light with the color of the irregular reflection portion 214 through the convex portion 212. In addition, since the light that has reached the tip of the scale portion 21 is reflected in the observer direction by the reflecting surface 213, the tip portion of the scale portion 21 can be strongly shined, so that the display expression is further innovative and aesthetic.
