Description

本発明は、車両用表示装置に関し、特に光源から照射される光による画像を乗員に視認させる車両用表示装置に関する。   The present invention relates to a vehicle display device, and more particularly to a vehicle display device that allows an occupant to visually recognize an image generated by light emitted from a light source.

この種の車両用表示装置として、例えば下記特許文献１に記載されているように、運転席に対向するダッシュパネル（構造材）内にＴＦＴ型液晶表示器が組み込まれたものが知られている。この特許文献１に記載された車両用表示装置では、ＴＦＴ型液晶表示器に車両状態（例えば車両のスピード）を表示するメータ画像が表示され、このメータ画像が乗員に視認されるようになっている。
特開２００７−１４５２４１号公報 As this type of vehicle display device, for example, as described in Patent Document 1, a TFT type liquid crystal display is incorporated in a dash panel (structural material) facing a driver's seat. . In the vehicle display device described in Patent Document 1, a meter image for displaying a vehicle state (for example, vehicle speed) is displayed on a TFT type liquid crystal display, and this meter image is visually recognized by an occupant. Yes.
JP 2007-145241 A

しかしながら、上記特許文献１に記載された車両用表示装置においては、ダッシュパネル内に同ダッシュパネルとは明らかに別素材の物体であるＴＦＴ型液晶表示器が組み込まれていると認識される。このため、一体感のあるダッシュパネル表面を構成することが困難であった。すなわち、ダッシュパネルにおいてＴＦＴ型液晶表示器が組み込まれた部分とそうでない部分、すなわち画像の表示領域と非表示領域とが見切り線（境界線）によって明らかに分割されており、外観上の一体感（シームレス感）が損なわれるという問題があった。また、この特許文献１に記載された車両用表示装置では、乗員がＴＦＴ型液晶表示器を直接的に視認できるようにダッシュパネルに液晶表示器を組み込む必要があるので、ダッシュパネルの外形の設計に際してデザイン的な制約が多いという問題もあった。   However, in the vehicle display device described in Patent Document 1, it is recognized that a TFT liquid crystal display, which is an object made of a material different from the dash panel, is incorporated in the dash panel. For this reason, it was difficult to construct a dash panel surface with a sense of unity. That is, in the dash panel, the portion where the TFT type liquid crystal display is incorporated and the portion where it is not, that is, the display region and the non-display region of the image are clearly divided by the parting line (boundary line). There was a problem that (seamlessness) was impaired. In addition, in the vehicle display device described in Patent Document 1, it is necessary to incorporate a liquid crystal display into the dash panel so that an occupant can directly view the TFT liquid crystal display. There was also a problem that there were many design restrictions.

本発明の課題は、外観上の一体感があり、また光源が組み込まれる構造材のデザインの自由度を向上させ得る車両用表示装置を提供することにある。   An object of the present invention is to provide a vehicle display device that has a sense of unity in appearance and can improve the degree of freedom in designing a structural material in which a light source is incorporated.

課題を解決するための手段及び発明の効果Means for Solving the Problems and Effects of the Invention

上記課題を解決するために、本発明の車両用表示装置は、車室内にて構造材の内部に組み込まれ、構造材に形成された開口部を通して構造材の内側から外側へ光を照射し同光による画像を乗員に視認させる光源と、開口部を覆うように構造材の表面に貼付される透過性ウレタン合皮とを備え、光源から光が照射されない状態では、透過性ウレタン合皮の皮模様を乗員に視認させ、光源から光が照射された状態では、構造材の開口部を通して透過性ウレタン合皮を透過する部位を表示領域として表示される画像を乗員に視認させることを特徴とする。この場合、例えば、構造材は、インストルメントパネルであり、光源は、バックライトを有する液晶表示器または光源基板を有する発光素子であると好適である。また、画像は、エンジン作動中の車両状態または乗員への警告を表示するメータ画像であると好適である。   In order to solve the above-mentioned problems, a display device for a vehicle according to the present invention is incorporated in a structural material inside a vehicle interior, and radiates light from the inside to the outside of the structural material through an opening formed in the structural material. A light source that allows an occupant to visually recognize an image of light and a transparent urethane synthetic leather that is attached to the surface of the structural material so as to cover the opening. When the pattern is made visible to the occupant and light is emitted from the light source, the occupant visually recognizes the image displayed as a display area through the transparent urethane synthetic leather through the opening of the structural material. . In this case, for example, the structural material is preferably an instrument panel, and the light source is preferably a liquid crystal display having a backlight or a light emitting element having a light source substrate. The image is preferably a meter image that displays a vehicle state during engine operation or a warning to an occupant.

これによれば、光源から光が照射されない状態では、構造材の表面に貼付された透過性ウレタン合皮の皮模様のみが乗員に視認される。一方、光源から光が照射された状態では、構造材の開口部を通して透過性ウレタン合皮の表示領域に表示される画像が乗員に視認されるようになる。このため、構造材内に同構造材とは明らかに別素材の物体が組み込まれているとは認識されなくなるので、あたかも一素材のみで構成されているかのような一体感のある構造材表面を構成することが可能である。すなわち、構造材の外観上、画像の表示領域と非表示領域間の見切り線が存在しないように構成することができるので、構造材を見たときに一体感を感じさせることができる。また、構造材としてのインストルメントパネルの内部に、光源としての液晶表示器または発光素子を組み込むようにした場合には、従来技術の表示装置とは異なり、液晶表示器等を乗員に直接的に視認させることを前提としてインストルメントパネルの外形を設計する必要がないので、インストルメントパネルのデザイン的な自由度を向上させることができる。   According to this, in the state where light is not irradiated from the light source, only the skin pattern of the permeable urethane synthetic leather stuck on the surface of the structural material is visually recognized by the occupant. On the other hand, when light is emitted from the light source, an image displayed on the display area of the permeable urethane synthetic leather is visually recognized by the occupant through the opening of the structural material. For this reason, since it is no longer recognized that an object of a different material from the structural material is incorporated in the structural material, the surface of the structural material with a sense of unity is as if it is composed of only one material. It is possible to configure. In other words, the structure material can be configured such that there is no parting line between the image display area and the non-display area, so that a sense of unity can be felt when the structure material is viewed. In addition, when a liquid crystal display or a light emitting element as a light source is incorporated inside an instrument panel as a structural material, unlike a display device of the prior art, the liquid crystal display or the like is directly connected to an occupant. Since it is not necessary to design the outer shape of the instrument panel on the assumption that it is visually recognized, the design freedom of the instrument panel can be improved.

本発明の実施に際して、透過性ウレタン合皮は、光源から光が照射されない状態にて透過性ウレタン合皮側から構造材側への視認性を妨げる板材を介して構造材に貼付されるように構成するとよい。   In carrying out the present invention, the permeable urethane synthetic leather is attached to the structural material via a plate material that hinders the visibility from the permeable urethane synthetic leather side to the structural material side in a state where light is not irradiated from the light source. Configure.

これによれば、板材によって、光源から光が照射されない状態にて、透過性ウレタン合皮側から構造材側への視認性が妨げられる。このため、透過性ウレタン合皮しか視認できない状態から、透過性ウレタン合皮の表面に画像が浮き出すような演出を効果的に高めることができる。また、板材によって、透過性ウレタン合皮を補強する効果も得ることができる。   According to this, the visibility from the transparent urethane leather side to the structural material side is hindered by the plate material in a state where light is not irradiated from the light source. For this reason, it is possible to effectively enhance such an effect that an image appears on the surface of the permeable urethane synthetic leather from a state where only the permeable urethane synthetic leather is visible. Moreover, the effect which reinforces a permeable urethane synthetic leather with a board | plate material can also be acquired.

以下、本発明の一実施形態について図面を用いて説明する。図１は本発明に係る車両用表示装置の一実施形態の作動状態を模式的に示す外観図、図２は図１の２−２断面図、図３は図１の３−３断面図である。この車両用表示装置は、構造材としてのインストルメントパネル１０（以下、単にインパネ１０という）の内部にて液晶表示器２１および複数の発光素子２２を備え、インパネ１０の外部にて透過性ウレタン合皮３１およびスモークアクリル３２を備えている。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is an external view schematically showing an operating state of an embodiment of a vehicle display device according to the present invention, FIG. 2 is a sectional view taken along the line 2-2 in FIG. 1, and FIG. 3 is a sectional view taken along the line 3-3 in FIG. is there. The vehicle display device includes a liquid crystal display 21 and a plurality of light emitting elements 22 inside an instrument panel 10 (hereinafter simply referred to as an instrument panel 10) as a structural material. A skin 31 and smoked acrylic 32 are provided.

インパネ１０は、その表面がフラット面あるいは緩やかな湾曲面に形成されている。インパネ１０の運転席に対向した部位の上部位置には、開口部１１が形成され、開口部１１の下部位置には、開口部１１よりも小さな複数の開口部１２が形成されている。なお、図３では、開口部１２が３つの場合を例示してある。   The instrument panel 10 has a flat surface or a gently curved surface. An opening 11 is formed at an upper position of a portion of the instrument panel 10 facing the driver's seat, and a plurality of openings 12 smaller than the opening 11 are formed at a lower position of the opening 11. In addition, in FIG. 3, the case where the opening part 12 is three is illustrated.

液晶表示器２１（光源）は、開口部１１の所定の組み付け部に組み付けられている。液晶表示器２１は、例えば透過型の液晶パネルを用いた液晶ディスプレイ２１ａと、ＬＥＤや冷陰極管などを用いたバックライト２１ｂを備えており、バックライト２１ｂから照射された光が液晶ディスプレイ２１ａを透過し、開口部１１を通してインパネ１０の外側へ照射される。   The liquid crystal display 21 (light source) is assembled to a predetermined assembly portion of the opening 11. The liquid crystal display 21 includes a liquid crystal display 21a using, for example, a transmissive liquid crystal panel, and a backlight 21b using an LED, a cold cathode tube, or the like, and light emitted from the backlight 21b passes through the liquid crystal display 21a. The light passes through and is irradiated to the outside of the instrument panel 10 through the opening 11.

この液晶表示器２１は、イグニッションスイッチのオンにより図示を省略する制御部からの制御信号に応じて、スピードメータ、タコメータ、燃料残量表示メータ、水温表示メータ、オド／トリップメータ、シフトポジションなどエンジン作動中の車両状態を表す画像を表示可能とされている。なお、図１では、車両状態を表す画像のうち、スピードメータ（数字とバーグラフで表示したもの）を例示してある。   The liquid crystal display 21 is an engine such as a speedometer, a tachometer, a fuel remaining amount display meter, a water temperature display meter, an od / trip meter, and a shift position in accordance with a control signal from a control unit (not shown) when the ignition switch is turned on. It is possible to display an image representing the vehicle state during operation. In addition, in FIG. 1, the speedometer (what was displayed with the number and the bar graph) was illustrated among the images showing a vehicle state.

複数の発光素子２２（光源）は、例えばＬＥＤで構成されており、通電のための回路が形成された光源基板２３（光源）に実装されている。光源基板２３は、インパネ１０の裏面側の所定の組み付け部に組み付けられている。光源基板２３がインパネ１０に組み付けられた状態では、各発光素子２２が対応する開口部１２内に収容され、発光素子２２の光が開口部１２を通してインパネ１０の外側へ照射される。なお、各開口部１２には、発光素子２２の輝度ムラを抑制して発光素子２２による発光を均一にするための光拡散板２４が組み付けられている。   The plurality of light emitting elements 22 (light sources) are constituted by, for example, LEDs, and are mounted on a light source substrate 23 (light source) on which a circuit for energization is formed. The light source substrate 23 is assembled to a predetermined assembly part on the back side of the instrument panel 10. In a state where the light source substrate 23 is assembled to the instrument panel 10, each light emitting element 22 is accommodated in the corresponding opening 12, and light from the light emitting element 22 is irradiated to the outside of the instrument panel 10 through the opening 12. Each opening 12 is assembled with a light diffusing plate 24 for suppressing unevenness in luminance of the light emitting element 22 and making light emitted by the light emitting element 22 uniform.

透過性ウレタン合皮３１は、天然皮の外観を呈するように透過性のスモークウレタン樹脂を注型成形したものであり、例えば成形工程時にスモークアクリル３２と密着に張り合わされる。スモークアクリル３２（板材）の裏面には、液晶パネル２１ａに対向する部位に透過部３２ａが形成され、発光素子２２に対向する部位に透過部３２ｂが形成され、透過部３２ａ，３２ｂ以外の部位に遮光部３２ｃが形成されるようにマスク印刷が施されている。   The permeable urethane synthetic leather 31 is formed by casting a permeable smoke urethane resin so as to exhibit the appearance of a natural leather. For example, the permeable urethane synthetic leather 31 is closely adhered to the smoke acrylic 32 during the molding process. On the back surface of the smoked acrylic 32 (plate material), a transmission part 32a is formed at a part facing the liquid crystal panel 21a, a transmission part 32b is formed at a part facing the light emitting element 22, and a part other than the transmission parts 32a and 32b is formed. Mask printing is performed so that the light shielding part 32c is formed.

透過部３２ｂは、エンジン作動中の各種警告インジケータ（例えば、リヤライト警告、エンジンチェック警告、シートベルト警告、ハイビーム警告、ドア警告、ブレーキ警告、排気音警告、オイル警告、チャージ警告、ターン方向）を表す画像が表示されるように透明の絵柄模様に形成されている。なお、図１では、各種警告を表す画像のうち、ブレーキ警告、ドア警告およびシートベルト警告を例示してある。   The transmission part 32b represents various warning indicators (for example, rear light warning, engine check warning, seat belt warning, high beam warning, door warning, brake warning, exhaust sound warning, oil warning, charge warning, turn direction) during engine operation. A transparent pattern is formed so that an image is displayed. FIG. 1 illustrates a brake warning, a door warning, and a seat belt warning among images representing various warnings.

遮光部３２ｃは、透過部３２ａ，３２ｂ以外の部分から光が外側へ漏れ出すことを抑制する。これにより、スモークアクリル３２の透過部３２ａ，３２ｂに対向する透過性ウレタン合皮３１の部位が、各種画像を表示するための表示領域Ｄとして機能するようになっている。また、遮光部３２ｃは、透過性ウレタン合皮３１およびスモークアクリル３２が有するスモーク機能との重畳作用によって、透過性ウレタン合皮３１側から見たインパネ１０側への視認性を妨げる機能（特に、液晶表示器２１の外枠を見えなくする）も果たす。   The light shielding part 32c suppresses light from leaking outside from parts other than the transmission parts 32a and 32b. Thereby, the site | part of the transparent urethane synthetic | combination leather 31 which opposes the permeation | transmission part 32a, 32b of the smoked acrylic 32 functions as the display area D for displaying various images. Further, the light shielding portion 32c has a function of hindering visibility to the instrument panel 10 viewed from the permeable urethane synthetic leather 31 side by superimposing the permeable urethane synthetic leather 31 and the smoke function of the smoke acrylic 32 (particularly, The outer frame of the liquid crystal display 21 is made invisible).

次に、上記のように構成した本実施形態の作動について説明する。イグニッションスイッチのオフ時、液晶表示器２１のバックライト２１ｂおよび発光素子２２から光が照射されない状態では、透過性ウレタン合皮３１、スモークアクリル３２自体およびスモークアクリル３２の遮光部３２ｃによって透過性ウレタン合皮３１側からインパネ１０側への視認性が妨げられている。このため、図４に示すように、乗員はステアリングホイールＳ越しに、透過性ウレタン合皮３１の皮模様のみを視認することができる。   Next, the operation of the present embodiment configured as described above will be described. When the ignition switch is off, light is not irradiated from the backlight 21b and the light emitting element 22 of the liquid crystal display 21, and the transparent urethane synthetic leather 31, the smoke acrylic 32 itself, and the light shielding portion 32c of the smoke acrylic 32 are used. Visibility from the skin 31 side to the instrument panel 10 side is hindered. For this reason, as shown in FIG. 4, the occupant can visually recognize only the skin pattern of the permeable urethane synthetic leather 31 through the steering wheel S.

一方、イグニッションスイッチのオンにより、液晶表示器２１のバックライト２１ｂおよび発光素子２２から光が照射された状態では、図１に示すように、乗員はステアリングホイールＳ越しに、透過性ウレタン合皮３１の表示領域Ｄに表示される車両状態および乗員に対する各種警告を表すメータ画像を視認できるようになる。   On the other hand, when light is emitted from the backlight 21b and the light emitting element 22 of the liquid crystal display 21 by turning on the ignition switch, the occupant passes through the steering wheel S through the transparent urethane synthetic leather 31 as shown in FIG. The meter image representing the vehicle state displayed on the display area D and various warnings for the occupant can be visually recognized.

したがって、この実施形態によれば、インパネ１０内に同インパネ１０とは明らかに別素材の物体が組み込まれているとは認識されなくなるので、あたかも一素材のみで構成されているかのような一体感のあるインパネ表面を構成することが可能である。すなわち、インパネ１０の外観上、メータ画像の表示領域Ｄと非表示領域間の見切り線が存在しないように構成することができるので、インパネ１０を見たときに一体感を感じさせることができる。また、インパネ１０の内部に、バックライト２１ｂを有する液晶表示器２１および光源基板２３を有する発光素子２２を組み込むようにしたので、従来技術の表示装置とは異なり、液晶表示器等を乗員に直接的に視認させることを前提としてインパネの外形を設計する必要がなくなる。その結果、例えば液晶表示器等に表示されるメータ画像のフロントウィンドウへの映り込みを防止する等のためのフードを小さく形成することが可能になる等、インパネ１０のデザイン的な自由度を向上させることができる。   Therefore, according to this embodiment, since it is not recognized that an object of a different material from the instrument panel 10 is clearly incorporated in the instrument panel 10, it feels as if it is composed of only one material. It is possible to construct a certain instrument panel surface. In other words, the instrument panel 10 can be configured so that there is no parting line between the display area D and the non-display area of the meter image, so that a sense of unity can be felt when the instrument panel 10 is viewed. Further, since the liquid crystal display 21 having the backlight 21b and the light emitting element 22 having the light source substrate 23 are incorporated in the instrument panel 10, the liquid crystal display or the like is directly attached to the occupant unlike the conventional display device. Therefore, it is not necessary to design the outer shape of the instrument panel on the assumption that it is visually recognized. As a result, for example, it is possible to form a small hood for preventing the meter image displayed on the liquid crystal display or the like from being reflected on the front window, and the design freedom of the instrument panel 10 is improved. Can be made.

また、上記実施形態では、液晶表示器２１のバックライト２１ｂおよび発光素子２２から光が照射されない状態にて、透過性ウレタン合皮３１、スモークアクリル３２自体およびスモークアクリル３２の遮光部３２ｃによって透過性ウレタン合皮３１側からインパネ１０側への視認性が妨げられる。これにより、透過性ウレタン合皮３１しか見えない状態から、透過性ウレタン合皮３１の表面（表示領域Ｄ）にメータ画像が浮き出すような演出を効果的に高めることができる。また、透過性ウレタン合皮３１とスモークアクリル３２を貼り合わせることによって、透過性ウレタン合皮３１を補強する効果も得ることができる。   Moreover, in the said embodiment, in the state which is not irradiated with the light from the backlight 21b and the light emitting element 22 of the liquid crystal display 21, the transparent urethane synthetic leather 31, the smoke acrylic 32 itself, and the light shielding part 32c of the smoke acrylic 32 transmit light. Visibility from the urethane synthetic leather 31 side to the instrument panel 10 side is hindered. Thereby, it is possible to effectively enhance an effect that the meter image is raised on the surface (display area D) of the permeable urethane synthetic leather 31 from the state where only the permeable urethane synthetic leather 31 is visible. Moreover, the effect which reinforces the permeable urethane synthetic leather 31 can also be acquired by bonding the permeable urethane synthetic leather 31 and the smoked acrylic 32 together.

なお、上記実施形態では、透過性ウレタン合皮３１、スモークアクリル３２自体およびスモークアクリル３２の遮光部３２ｃを重ね合わせることによって、液晶表示器２１のバックライト２１ｂおよび発光素子２２から光が照射されない状態でのブラックアウト効果をより一層高めることができた。しかし、これに限らず、例えば透過性ウレタン合皮３１およびスモークアクリル３２のうちの少なくとも一方のスモーク濃度を高めるようにすれば、透過性ウレタン合皮３１およびスモークアクリル３２の両部材にスモーク機能を持たせる必要はなく、あるいはスモークアクリル３２の遮光部３２ｃを省略することもできる。   In the above embodiment, light is not irradiated from the backlight 21b and the light emitting element 22 of the liquid crystal display 21 by overlapping the transparent urethane synthetic leather 31, the smoke acrylic 32 itself, and the light shielding portion 32c of the smoke acrylic 32. The blackout effect in the can was further enhanced. However, the present invention is not limited to this. For example, if the smoke concentration of at least one of the permeable urethane synthetic leather 31 and the smoked acrylic 32 is increased, the smoke function is provided to both the permeable urethane synthetic leather 31 and the smoked acrylic 32. It is not necessary to have it, or the light shielding part 32c of the smoke acrylic 32 can be omitted.

また、上記実施形態では、構造材としてのインパネ１０の内部に、光源としての液晶表示器２１および発光素子２２を組み込むように構成したが、これに加えてまたは代えて、例えばドアなどに上記した各種警告インジケータを表示する発光素子を組み込んで、透過性ウレタン合皮３１で覆うように構成してもよい。また、後部座席の乗員から視認できるように、前席シートバックに上記した各種警告インジケータや時刻を表示する発光素子を組み込んで、透過性ウレタン合皮で覆うように構成してもよい。   Moreover, in the said embodiment, although comprised so that the liquid crystal display 21 and the light emitting element 22 as a light source might be integrated in the inside of the instrument panel 10 as a structural material, it described above, for example in a door etc. in addition to or instead of this. A light emitting element that displays various warning indicators may be incorporated and covered with the transparent urethane synthetic leather 31. Moreover, you may comprise so that it may be visually recognized from the passenger | crew of a rear seat, the above-mentioned various warning indicators and the light emitting element which displays time are integrated in a front seat back, and it covers with a transparent urethane synthetic leather.

また、光源としてタッチ操作パネルを有するエアコンコントロールパネルやナビゲーション装置を採用し、タッチ操作パネルにおける操作スイッチの位置が点灯表示されるように設定すれば、液晶表示器２１の場合と同様、これらをインパネ１０の内部に組み込んで、透過性ウレタン合皮３１で覆うように構成することも可能である。   Further, if an air conditioner control panel having a touch operation panel or a navigation device is adopted as a light source, and the position of the operation switch on the touch operation panel is set to be lit, the instrument panel, like the liquid crystal display 21, is used. It is also possible to configure so as to be incorporated in the interior of 10 and covered with a permeable urethane synthetic leather 31.
