Embodiments of a vehicle instrument device according to the present invention will be described below with reference to the drawings of FIGS.
As shown in FIG. 1, the vehicular instrument device 1 in this embodiment includes a plurality of meters such as a speedometer 2 and a tachometer (not shown). Further, as shown in FIG. 2, the vehicular instrument device 1 includes an outer lens 11 in front of the dial 3 of the speedometer 2 that is separated from the dial 3 by a predetermined dimension. In the following description, in FIG. 2, the arrow X1 direction is the front, and the arrow X2 direction is the rear.

The dial plate 3 is formed of a resin that transmits light (light transmissive resin), has a substantially circular shape when viewed from the front, and has a trapezoidal cross-sectional shape. The dial plate 3 is disposed inside the cylindrical portion 21 of the frame 20 and is attached to the front surface of the support base 23 provided on the front side of the base frame 22.
A front surface (that is, a surface facing the outer lens 11) of the dial 3 is a design surface 4. The design surface 4 is a flat portion 5 having a circular center, and the outer side of the flat portion 5 is a slope 6 that gradually falls rearward from the periphery of the flat portion 5 toward the radially outer side. The inclined surface 6 forms an angle of 45 degrees with respect to the flat portion 5. And as shown in FIG. 1, the scale 7 is provided in the circumferential direction predetermined range of the inclined surface 6 of the design surface 4, and consists of the number which shows a speed on the outer peripheral part of the flat part 5 inside the scale 7 in the radial direction. Character 8 is displayed at 20 km / h intervals. Moreover, the area | region where the scale 7 is provided in the slope 6 of the design surface 4 is formed in the convex curve 6a, and the area | region where the scale 7 is not provided is formed in the flat surface 6b.
In the dial plate 3 of this embodiment, the scale 7 and the character 8 are configured to include a pearl printing layer containing a pearl pigment, and the design surface 4 excluding the scale 7 and the character 8 is subjected to metallic printing. Yes. This will be described in detail later.

The pointer 9 of the speedometer 2 is disposed in front of the dial 3 and is rotated by an angle corresponding to the vehicle speed by a movement 10 provided at the rear of the dial 3. The tip of the pointer 9 is located in front of the slope 6 on the design surface 4 of the dial 3. The movement 10 is fixed to the base frame 22.
A diffusion plate 13 is installed between the dial plate 3 and the support base 23, and a plurality of white LEDs 14 as light sources are attached to the rear of the diffusion plate 13. The diffusing plate 13 is formed of a light-transmitting resin and has a donut plate shape. The diffusing plate 13 diffuses the light of the LED 14 incident from the introducing portion 13a to illuminate the dial plate 3 from the rear. The diffuser plate 13 and the LED 14 constitute a backlight illuminating means 15. In this embodiment, the backlight illuminating means 15 is turned off during daytime and turned on at dusk or at night for illumination.

A gradation illumination means 30 is provided between the cylindrical portion 21 of the frame 20, the support base 23 and the dial 3. The gradation illumination unit 30 includes an LED 31 as a light source and a light guide 32.
The LEDs 31 are composed of white LEDs, and are arranged on the outer side in the radial direction of the support base 23. A plurality of LEDs 31 are arranged at predetermined intervals in the circumferential direction.

  The light guide 32 is formed of a light-transmitting resin, has a ring shape, is disposed in front of the LED 31 and radially outside the dial plate 3, and is attached to the inside of the cylindrical portion 21 of the frame 20. The front end surface 32a of the light guide 32 is formed in a plane parallel to the flat portion 5 on the design surface 4 of the dial 3, and is arranged at substantially the same position as the flat portion 5 in the front-rear direction. In this embodiment, the front end face 32 a of the light guide 32 is located slightly behind the flat portion 5. The inner peripheral surface 32 b of the light guide 32 is formed in a plane orthogonal to the front end surface 32 a, and the rear end of the inner peripheral surface 32 b is in contact with the outer peripheral edge of the slope 6 on the design surface 4 of the dial 3. Therefore, the distance from the inner peripheral surface 32b of the light guide 32 to the inclined surface 6 becomes longer as it advances from the rear side to the front side. Blue printing (coating film) is applied to the inner peripheral surface 32b.

  A blind ring 33 is attached in front of the gradation illumination means 30. The blind ring 33 is formed of a resin that does not transmit light (light non-transparent resin), has a ring shape, is disposed in front of the light guide 32, and is spaced apart from the inclined surface 6 on the design surface 4 of the dial 3. Has been. The blind ring 33 is attached to the inside of the cylindrical portion 21 of the frame 20 via a fixing ring 34. The fixing ring 34 is also made of a light-impermeable resin, has a ring shape with an L-shaped cross section, and the blind ring 33 is integrally attached to the inside of the fixing ring 34. The blind ring 33 has a substantially triangular cross section whose diameter increases as it advances forward, and the rear end surface of the blind ring 33 and the rear end surface of the fixing ring 34 are flush with each other and are in contact with the front end surface 32a of the light guide 32. . The inner peripheral surface 33a of the blind ring 33 protrudes radially inward from the inner peripheral surface 32b of the light guide 32, and covers the outer peripheral edge of the slope 6 on the design surface 4 of the dial 3 from the front. Thereby, the gradation illumination means 30 is hidden by the blind ring 33 and the fixed ring 34.

In this embodiment, the gradation illumination means 30 is controlled to be turned on / off in conjunction with the backlight illumination means 15, so the gradation illumination means 30 is also turned off during the daytime, and at dusk or at night. Turn on and illuminate.
In this gradation illumination means 30, the light emitted from the LED 31 and incident on the light guide 32 is blocked from being emitted forward by the blind ring 33 and the fixing ring 34, and is emitted only from the inner peripheral surface 32 b of the light guide 32. It becomes possible. That is, only the inner peripheral surface 32 b becomes the exit of the light guide 32. The outgoing light emitted radially inward from the inner peripheral surface 32 b of the light guide 32 is colored blue by the blue printing (coating film) applied to the inner peripheral surface 32 b, and the design surface 4 of the dial 3. The slope 6 is irradiated. And the blue emitted light irradiated to the slope 6 reflects in the slope 6, and reflected light advances ahead. Here, since the inclined surface 6 forms an angle of 45 degrees with respect to the flat portion 5, the blue reflected light reflected by the inclined surface 6 proceeds in a direction perpendicular to the flat portion 5, and reaches the outer lens 11. Irradiated, and further vertically passes through the outer lens 11.

In this embodiment, since the front end surface 32a of the light guide 32 is located slightly behind the flat portion 5 in the design surface 4, the light emitted from the inner peripheral surface 32b of the light guide 32 is extracted. Irradiation is applied almost exclusively to the inclined surface 6 of the design surface 4, and irradiation to the flat portion 5 is suppressed.
Further, since the inner peripheral surface 33a of the blind ring 33 protrudes radially inward from the inner peripheral surface 32b of the light guide 32, the reflected light that is emitted from the light guide 32 and reflected by the inclined surface 6 of the design surface 4 is reflected. The blind ring 33 can be restricted so as not to spread outward in the radial direction.

  Further, as described above, since the distance from the inner peripheral surface 32b of the light guide 32 to the inclined surface 6 increases as it advances from the rear side to the front side, the reflected light reflected on the radially outer side of the inclined surface 6 is increased. It becomes brighter than the reflected light reflected on the radially inner side of the slope 6. Thereby, blue gradation illumination which becomes gradually darker from the radially outer side to the radially inner side with respect to the inclined surface 6 is performed.

In particular, since the region where the scale 7 is provided on the inclined surface 6 is formed on the convex curved surface 6a, the reflected light is more flat on the design surface 4 as the convex surface 6a is more radially inward of the inclined surface 6. The angle formed with 5 is reduced. Therefore, gradation is clearer on the slope 6 formed on the convex curved surface 6a than on the slope 6 formed on the flat surface 6b.
Here, the shape of the convex curved surface 6 a is set so that the reflected light reflected at a position corresponding to the inner peripheral edge 33 a of the blind ring 33 in the radial direction proceeds in a direction perpendicular to the flat portion 5. Then, the outermost side of the slope 6 that can be seen inside the blind ring 33 when viewed from the front can be brightened, and the gradation can be made clearer.

  Next, the structure of the dial 3 will be described in detail. FIG. 3 is a partial perspective view of the dial 3 showing a section where the character 8 is displayed in cross section, and FIG. 4 is a cross-sectional view thereof. The dial plate 3 includes a substrate 41, a display coloring layer (printing layer) 42 formed by printing on the surface of the substrate 41, and a pearl printing layer (printing layer) formed by printing on the surface of the display coloring layer 42. 43 and a background coloring layer 44 formed on the surface of the pearl printing layer 43 by printing or the like.

The substrate 41 is made of a transparent or translucent light transmissive resin. The display coloring layer 42 is made of a white light-transmitting coating film. The pearl print layer 43 is made of a light-transmitting coating film formed by printing pearl ink having a pearl pigment. The background coloring layer 44 is made of a light-impermeable coating film having a metallic color, and has an opening 44 a that is opened following the shape of the character 8. Here, examples of the metallic color include metallic colors such as silver or gold.
That is, the pearl print layer 43 is exposed through the opening 44 a of the background coloring layer 44, and the pearl printing layer 43 and the background coloring layer 44 exposed from the opening 44 a form the surface of the design surface 4. The character 8 with the background colored layer 44 as the background has a structure in which the surface side of the display colored layer 42 is covered with the pearl print layer 43. Although the structure of the character 8 portion will be described here, the scale 7 portion has the same structure.

The pearl pigment is named after the characteristics exhibited by having a structure similar to that of natural pearls. As shown in FIG. 5, the pearl has a structure in which a protein layer 51 and a calcium carbonate layer 52 having transparent and different refractive indexes are alternately overlapped around the nucleus, and the light incident on the surface of the pearl is a protein layer. Multiple reflections are regularly made at the boundary between the layer 51 and the calcium carbonate layer 52, and the reflected lights interfere with each other, resulting in an interference color and gloss peculiar to pearl.
The pearl pigment reproduces the pearl color by a layered arrangement of mica or SiO ₂ , Al ₂ O ₃ having a low refractive index and a metal oxide such as titanium oxide or iron oxide having a high refractive index.

Explaining with the pearl pigment model in FIG. 6, a multi-layer transparent coating film is formed by applying a metal oxide to the surface of mica, SiO ₂ , Al ₂ O ₃ , and by regular multiple reflection of light by this coating film, Pearl interference color is realized.
In the pearl print layer 43 of this embodiment, as shown in FIG. 7, the pearl pigment is layered in the pearl print layer 43 formed of a coating film in which the ink having the pearl pigment is printed in a transparent or translucent thin plate shape. Oriented and complex multiple reflection of light. As a result, when light is incident on the coating film and reflected internally, the light reflected in the pearl print layer 43 interferes with the light reflected on the surface of the pearl print layer 43, and the reflected light is in the same phase. Reinforce each other and cancel each other when they are out of phase.

  According to the dial plate 3 thus configured, the irradiation light applied to the design surface 4 of the dial plate 3 is applied to the display coloring layer 42 via the pearl print layer 43. The pearl print layer 43 has a larger reflection luminance than the reflection luminance of the display coloring layer 42 due to the reflection luminance characteristics, and increases the reflection luminance of the characters 8 as compared with the case where the pearl print layer 43 is not provided. Therefore, the contrast of the character 8 with respect to the background part which consists of the background coloring layer 44 can be improved rather than the case where the pearl print layer 43 is not provided.

In the case of a pearl pigment, the wavelength (λ) of the interfered visible light is proportional to the product of the thickness (d) of the layer constituting the pearl pigment and the refractive index (n) of the material constituting the layer (λ∝ d · n), it is possible to arbitrarily specify the wavelength of visible light to be interfered by changing the thickness of each layer and the metal oxide on the surface. A certain pearl color can be obtained. Incidentally, when the layer thickness is 40-60 nm, it is silver, when it is 60-80 nm, it is yellow (transmitted light: blue), when it is 80-100 nm, it is red (transmitted light: green), when it is 100-140 nm, it is blue (transmitted light: yellow), 120 At ˜160 nm, a green (transmitted light: red) interference color can be obtained.
In this embodiment, in order to make the color of the character 8 white, the display coloring layer 42 is white, and the pearl pigment has a layer thickness capable of obtaining interference light having the same color as the color of the display coloring layer 42 (white). For example, a pearl pigment that emits silver interference light is selected.

  FIG. 8 shows a character plate having a pearl print layer 43 containing a pearl pigment that emits silver interference light in a dial plate having a metallic background coloring layer 44 as a background portion (referred to as a metal dial plate in FIG. 8). 8 is referred to as a pearl print character), and a character that does not include the pearl print layer 43, that is, a character that does not use a pearl pigment (referred to as a normal character in FIG. 8) is used. FIG. 8 shows the results of comparative experiments for contrast (in FIG. 8, the case of pearl printed characters is denoted as pearl contrast, and the case of ordinary characters is denoted as normal contrast). The reflective brightness of the metal dial was the same for both.

From this experimental result, regardless of the brightness of the incident external light, the pearl print character has higher reflection brightness than the normal character, and therefore the contrast with the background part is also better for the pearl print character than the normal character. Proved to be great. Moreover, in the case of normal characters, the contrast is very small when the brightness of the incident light is small, and the contrast gradually increases as the brightness of the incident light increases. In the case of letters, it can be confirmed that the contrast is almost constant and extremely large regardless of the brightness of incident external light.
For this reason, when white normal characters are applied to the metal dial plate, the character visibility with respect to the background portion is small, and thus the visibility of the characters deteriorates. However, as in the vehicle instrument device 1 of this embodiment, When white pearl print characters are applied to the dial, the contrast of the pearl print characters with respect to the background portion is extremely high, so that the visibility of the characters 8 is greatly improved.

  When the LED 14 of the backlight illumination means 15 is turned on at night or the like, the white light of the LED 14 diffused by the diffusion plate 13 is irradiated from the back side of the dial plate 3. Has light transmissivity, the light emitted from the diffusion plate 13 passes through the scale 7 and the character 8 and is emitted forward, so that the scale 7 and the character 8 are brightly raised. On the other hand, the design surface 4 excluding the scale 7 and the character 8 is covered with the background coloring layer 44 which is a light-impermeable coating, so that the light irradiated from the diffusion plate 13 is the scale 7 and the character 8. Cannot pass through the design surface 4 except for this, and therefore this portion looks dark when viewed from the front. Thereby, even when the LED 14 of the backlight illumination means 15 is turned on, the contrast of the scale 7 and the character 8 with respect to the background portion is very large and the visibility is extremely high.

  In the embodiment described above, the display coloring layer 42 and the pearl printing layer 43 are formed on the entire surface of the substrate 41. However, it is sufficient that the display coloring layer 42 and the pearl printing layer 43 are formed on the scale 7 and the character 8 portion. As shown in FIG. 9, the display coloring layer 42 and the pearl printing layer 43 may be laminated only at a portion corresponding to the opening 44 a of the background coloring layer 44. When the substrate 41 is formed of a light transmissive material, a pearl print layer 43 is formed on the surface side of the substrate 41 (that is, the design surface 4 side) as shown in FIG. The display coloring layer 42 may be formed on the back side.

As described above, according to the vehicular instrument device 1 of this embodiment, since the metallic surface printing is applied to the design surface 4 of the dial 3, it is possible to bring out a high-class feeling and a sporty feeling. Further, since the pearl print layer 43 that forms the scale 7 and the character 8 contains the pearl pigment, the visibility of the scale 7 and the character 8 is extremely high even when the LED 14 of the backlight illumination means 15 is not turned on.
Further, when the LED 14 of the backlight illumination means 15 is turned on at night or the like, the white light emitted from the diffusion plate 13 transmits only the scale 7 and the character 8 and is emitted forward, and the scale 7 and the character 8 are brightened. Since the surface is raised, the visibility of the scale 7 and the character 8 is very high at this time as well.

  In addition, since the LED 31 of the gradation illumination unit 30 is turned on simultaneously with the lighting of the LED 14 of the backlight illumination unit 15, as described above, the slope 6 (that is, the portion where the scale 7 is applied) on the design surface 4 of the dial 3. ), It is possible to perform blue gradation illumination that gradually becomes darker from the radially outer side toward the radially inner side. This gives a sense of luxury and sportiness. The gradation illumination means 30 illuminates the slope 6 of the design surface 4 with blue light, but hardly illuminates the flat portion 5, so that the scale 7 looks pale and the character 8 appears clear white for the driver.
