Japanese Unexamined Patent Publication No. 2014-206500

In the above-mentioned Patent Document 1, it is considered that the region adjacent to the irradiation region of the display board is a regulated region in which illumination is regulated by applying light-shielding printing. Then, it is considered that the light emitting portion is arranged so as to straddle the irradiation region and the regulation region. In a vehicle display device, a light emitting unit arranged so as to straddle an irradiation area and a regulation area is often adopted. For such a light emitting part, for example, it is desired to improve the appearance of the light emitting part by setting only a part having high lighting quality such as less uneven lighting in the lighting part as an irradiation area and intentionally shading other parts. It can be adopted because it is difficult to secure a space for arranging the light-emitting part, and in addition, the light emitting part is enlarged to improve the appearance.

Here, the diffusion portion of Patent Document 1 is arranged so as to overlap with the substantially irradiation region, but is also arranged so as to overlap a part of the regulation region. In such a diffused portion, the portion overlapping the irradiation region is sufficiently irradiated with the illumination light, so that it can emit bright light. However, the irradiation light is not sufficiently supplied to the portion overlapping the regulated region among the portions overlapping the diffused portion as compared with the portion overlapping the irradiation region. For this reason, the portion of the light emitting portion that overlaps with the regulated region does not emit sufficient light and becomes dark, causing deterioration in appearance.

The present invention has been made in view of the problems described above, and an object of the present invention is to provide a display device for a vehicle having a good appearance.

The present invention is a vehicle display device mounted on a vehicle.
An illumination unit having an irradiation region (44) that emits illumination light to the visual recognition side and a regulation region ( 45, 46) that is adjacent to the irradiation region and whose illumination is regulated.
It is provided with a light emitting unit which is arranged so as to straddle the irradiation area and the regulation area on the visual side of the illumination unit and is illuminated by the illumination light to emit light.
The light emitting part
The first is arranged so as to overlap the irradiation area, and is provided with an inclined reflection surface (76a) that is inclined so as to move away from the illumination unit as it goes from the irradiation area side to the regulation area side and reflects the illumination light from the irradiation area. Part (76) and
A second portion (80), which is arranged so as to overlap the regulation area and is provided with a diffusing portion for diffusing the illumination light reflected on the inclined reflecting surface, and
It is located on the opposite side of the second part with the first part in between, and has a contact part (78) that comes into contact with the regulated area .
The tilt angle of the second site with respect to the regulated region is larger than the tilt angle of the first site with respect to the irradiation region .

According to such an invention, among the light emitting portions arranged so as to straddle the irradiation region and the regulation region, the inclined reflection surface is provided at the first portion provided so as to overlap the irradiation region. Therefore, the illumination light emitted from the irradiation area of the illumination unit to the visual recognition side illuminates the first portion overlapping the irradiation region, and at that time, also incidents on the inclined reflection surface provided in the first portion. .. Here, since the inclined reflection surface is inclined so as to move away from the illumination unit from the irradiation region side to the regulation region side, the illumination light from the irradiation region is reflected to the regulation region side, which is regulated. Illumination light reaches the part that overlaps the area.

Here, the light emitting portion has a diffusing portion at a second portion provided so as to overlap the regulated region. By diffusing the illumination light reflected on the inclined reflecting surface by the diffusing portion, it is possible to emit light from the diffusing portion to the visual recognition side as well. As a result, even in the light emitting portion that overlaps the regulated region, the light is sufficiently brightly emitted. As described above, it is possible to provide a vehicle display device having a good appearance.

It is possible. As vehicle information, it is possible to adopt the vehicle speed, engine speed, remaining fuel, remaining battery, temperature of engine cooling water, and the like. In the present embodiment, a plurality of pointers 32a and 32b are provided in the pointer unit 30, of which the pointer indicating the speed of the vehicle is the main pointer 32a and the pointer indicating the remaining fuel amount is the sub-guideline 32b. ing. In the present embodiment, the rotation center of the main pointer 32a is defined as the pointer axis AX.

The rear end of the pointer shaft insertion tube portion 12a is in contact with the mounting board 20 with a small gap, and the pointer shaft light source portion 51 is located in the mounting board 20 surrounded by the pointer shaft insertion tube portion 12a. The light emitting element 51a of the above is arranged. When the light emitting element 51a emits light, the needle-shaped portion 34 of the pointer is illuminated.

The display plate 40 is a plate-shaped member generally also called a dial, and covers the opening 12d of the viewing side case component 12 from the viewing side and is held by the viewing side case component 12. The display board 40 is partially printed with semipermeable or light-shielding properties on the surface of a base material made of a translucent synthetic resin on the visible side, and displays vehicle information. In addition, instead of printing, painting may be applied. As shown in FIG. 1, the display plate 40 of the present embodiment is formed in a disk shape centered on the pointer axis AX.

An indicator lamp 41 is provided in a region of the display plate 40 facing the light passing cylinder portion 12b formed in a hollow tubular shape in the visible side case component 12. The indicator lamp 41 is configured by a transmissive region formed so as to be able to transmit light by semitransparent printing or exposure of a base material to form the outline of a mark indicating information of various vehicles. As the indicator lamp 41, there are an indicator lamp indicating the direction of the headlamp, an indicator lamp indicating various warnings, and the like.

As shown in FIG. 2, in the light passing cylinder portion 12b, one end is in contact with the mounting substrate 20 with a small gap, and the other end is in contact with the display plate 40 with a small gap. In the mounting substrate 20, a light emitting element 52a of the light source unit 52 for an indicator lamp is arranged on one end side inside the cylinder surrounded by the light passing cylinder portion 12b. When the light emitting element 52a corresponding to the indicator light 41 emits light, the indicator light 41 is turned on.

As shown in FIGS. 2 and 3, the light source unit 50 for the ring member is composed of a plurality of light emitting elements 50a arranged on the visible side of the mounting substrate 20. A light emitting diode element is adopted for each light emitting element 50a of the present embodiment, and each light emitting element 50a is connected to a power source through a wiring pattern on the mounting substrate 20, so that the introduction portion of the light guide prism member 60 is introduced. Illumination light is emitted toward 61. Each light emitting element 50a may be a light emitting element that emits light in a single color, or may be a multicolor light emitting element that can switch colors. Further, in the present embodiment, the same light emitting diode element is adopted for the light emitting elements 51a and 52a of the other light source units 51 and 52.

The light guide prism member 60 is formed of a synthetic resin such as acrylic resin or polycarbonate resin with high transmittance and translucency, and is formed between the mounting substrate 20 and the display plate 40, that is, a decorative ring member. It is arranged on the back side of 70. As shown in FIG. 3, the light guide prism member 60 is housed in a storage space 12e surrounded by a reflective wall portion 12c of the viewing side case component 12. The light guide prism member 60 integrally forms an introduction portion 61 and a lead-out portion 63.

The introduction portion 61 is provided so as to extend from the incident end 61a facing the light source portion 50 for the ring member toward the lead-out portion 63 on the visual recognition side and the outer peripheral side. There is no optical interface at the connection point between the introduction unit 61 and the lead-out unit 63, and the introduction unit 61 and the lead-out unit 63 are continuously formed.

The illumination light from the light emitting element 50a of the light source unit 50 for the ring member is introduced into the medium of the introduction unit 61 from the incident end 61a. The illumination light introduced inside is reflected at the interface between the introduction unit 61 and the accommodation space 12e, and is guided through the inside of the introduction unit 61 to the lead-out unit 63. Further, the illumination light emitted into the accommodation space 12e is also reflected by the mirror-like reflecting wall portion 12c, and is returned to the inside of the light guide prism member 60 again.

As shown in FIGS. 2 to 4, the lead-out unit 63 is arranged so as to face the decorative ring member 70 with the display plate 40 sandwiched between them. The lead-out unit 63 has an annular plate shape centered on the pointer axis AX. As shown in FIG. 5, in the lead-out unit 63, the lead-out surface 64 is formed in a planar shape on the visual side facing the display plate 40. In the lead-out portion 63, edge portions 65 are formed on the inner peripheral side and the outer peripheral side of the lead-out surface 64. With such a configuration, the lead-out surface 64 sandwiched between the edge portions 65 from both sides in the radial direction has an annular shape having a width in the radial direction. In the lead-out unit 63, a reflective surface 66 facing the back surface side is provided in a plane on the opposite side of the lead-out surface 64.

The illumination light guided from the introduction unit 61 to the lead-out unit 63 is reflected in the edge portion 65 and the reflection surface 66 inside the medium of the lead-out unit 63 and swirls in the circumferential direction to compare in the circumferential direction. It is distributed in a homogeneous density. Such illumination light is emitted from the lead-out surface 64 toward the display board 40 to the outside of the lead-out unit 63. At this time, the illumination light can be emitted relatively uniformly from the central portion 64a of the lead-out surface 64, but the edge portion 65 is formed on the inner peripheral portion 64b and the outer peripheral portion 64c located near the edge portion 65 of the lead-out surface 64. The illumination light may be uneven due to the influence of diffused reflection and the like.

The illumination light emitted from the lead-out surface 64 is incident on the display plate 40. Here, the irradiation region 44 and the regulation regions 45 and 46 are provided on the display plate 40 so as to face the lead-out portion 63.

The irradiation region 44 is provided in an annular shape at a portion of the lead-out surface 64 facing the central portion 64a. In the irradiation region 44, the surface of the display plate 40 is not printed, that is, the base material is exposed on both the visual side and the back side, so that the illumination light is transmitted and emitted to the visual side. It has become.

The regulation areas 45 and 46 are provided adjacent to the irradiation area 44. Specifically, the regulation region 45 is continuously provided at a portion of the lead-out surface 64 facing the inner peripheral portion 64b, and further on the inner peripheral side of the portion. The regulation region 46 is continuously provided at a portion of the lead-out surface 64 facing the outer peripheral portion 64c, and further on the outer peripheral side from the portion. In the restricted areas 45 and 46, the transmission of illumination light is restricted more than in the irradiated areas 44 by providing light-shielding printing on the surface of the display board 40. In particular, in the present embodiment, in the restricted areas 45 and 46, the black light-shielding layer is formed on the surface of the display board 40, so that the illumination light is almost light-shielded and absorbed.

Depending on the arrangement of the irradiation regions 44 and the regulation regions 45 and 46, the central portion 64a of the lead-out surface 64 is roughened by embossing or the like, while the inner peripheral portion 64b and the outer peripheral portion 64c are mirror surfaces. It is in the shape. By doing so, among the illumination lights reflected inside the medium of the lead-out unit 63, those that reach the inner peripheral portion 64b and the outer peripheral portion 64c are easily reflected inside the medium again and reach the central portion 64a. The portion is easily ejected and diffused toward the display plate 40 side. Therefore, it is possible to intensively emit the illumination light with less uneven illumination from the central portion 64a of the lead-out surface 64. Therefore, the irradiation region 44 facing the central portion 64a can efficiently emit illumination light with less uneven illumination to the viewing side.

The decorative ring member 70 is arranged on the visual side of the display plate 40 so as to face the light guide prism member 60 with the display plate 40 in between. The decorative ring member 70 is composed of a light-shielding wall portion 71, a light emitting main body portion 75, a smoke portion 73, and the like, and exhibits an annular shape centered on the pointer shaft AX.

The light-shielding wall portion 71 is formed on the outermost circumference of the decorative ring member 70 in a light-shielding annular shape by, for example, a synthetic resin. The light-shielding wall portion 71 is provided so as to extend from the outer peripheral side to the viewing side of the display plate 40 while inclining toward the inner peripheral side, thereby forming a standing wall on the outer periphery of the decorative ring member 70.

The light emitting main body portion 75 and the smoke portion 73 are arranged on the inner peripheral side of the light shielding wall portion 71 so as to straddle the irradiation region 44 of the display plate 40 and the regulation regions 45 and 46 on both sides in the radial direction. The light emitting body portion 75 and the smoke portion 73 are two-color molded parts made of different materials, and the light emitting main body portion 75 is arranged on the back surface side and the smoke portion 73 is arranged on the viewing side. As a whole, the light emitting main body portion 75 and the smoke portion 73 are formed in an annular shape that protrudes toward the visual recognition side from the inner peripheral side to the outer peripheral side in accordance with the inclined reflecting surface 76a described later.

The light emitting main body 75 has an annular shape in which the first portion 76 and the second portion 80 are integrally formed by a light diffusing material that diffuses illumination light. Here, the light diffusing material is, for example, a milky white material obtained by mixing diffusing particles such as beads or bubbles that diffuse illumination light with a translucent synthetic resin. Further, as the light diffusing material, silicone rubber or the like having light diffusing property can be adopted.

The first site 76 is an irradiation region superimposing site arranged on the inner peripheral side of the second site 80 so as to overlap the irradiation region 44. The first portion 76 is formed in the shape of an annular plate that inclines away from the display plate 40 as it goes from the irradiation region 44 side to the regulation region 46 side on the outer peripheral side, that is, from the inner peripheral side to the outer peripheral side. There is. In the first portion 76, the surface facing the back surface side and facing the irradiation region 44 of the display plate 40 is a mirror-like inclined reflecting surface 76a.

The inclined reflecting surface 76a is separated from the display plate 40 from the irradiation region 44 side toward the regulation region 46 side on the outer peripheral side, that is, from the inner peripheral side to the outer peripheral side in accordance with the longitudinal direction of the first portion 76. It is inclined like. The first portion 76 is set to have a substantially uniform thickness from the inner peripheral side to the outer peripheral side along the inclined surface 76.

An abutting portion 78 that comes into contact with the regulation region 45 on the inner peripheral side of the display plate 40 is provided on the inner peripheral side of the first portion 76, that is, the innermost peripheral portion of the light emitting main body portion 75. The thickness of the contact portion 78 is set so as to gradually decrease from the outer peripheral side to the inner peripheral side.

The second portion 80 is a regulated region overlapping portion arranged on the outer peripheral side of the first portion 76 so as to overlap the regulated region 46 on the outer peripheral side. The second portion 80 is formed in the shape of an annular plate extending substantially parallel to the light-shielding wall portion 71. Therefore, the second portion 80 is formed in an annular plate shape that inclines away from the display plate 40 toward the irradiation region 44 side from the regulation region 46 side, that is, from the outer peripheral side to the inner peripheral side. .. Here, the inclination angle of the second portion 80 with respect to the display plate 40 is much larger than that of the first portion 76, and is closer to 90 degrees. The second portion 80 is also set to have a substantially uniform thickness at each portion.

Such a first portion 76 and a second portion 80 are connected by a connecting portion 79 over the entire circumference. In this way, the radial cross section of the light emitting main body 75 has an L-shape or a V-shape, and a passage space 81 for passing the illumination light is formed between the light emitting main body portion 75 and the irradiation region 44 of the display plate 40. The connection portion 79 overlaps with the regulation region 46.

The smoke portion 73 is formed in the shape of a dark ring plate capable of semi-transparent illumination light, for example, by coloring a translucent synthetic resin in a smoke tone. The smoke portion 73 is arranged so that the light emitting main body portion 75 cannot be directly seen by the occupant by covering the entire light emitting main body portion 75 including the first portion 76 and the second portion 80 from the visual recognition side. Specifically, the smoke portion 73 is closely joined to the surface of the first portion 76 facing the viewing side. The outermost peripheral portion of the smoke portion 73 is sandwiched between the ridge portion 71a protruding inward from the light-shielding wall portion 71 and the light emitting main body portion 75.

As shown in FIG. 6, the illumination light emitted from the irradiation region 44 of the display plate 40 to the visual recognition side is incident on the inclined reflection surface 76a of the first portion 76 via the passing space 81. Since the inclined reflection surface 76a is formed in a mirror surface shape, a part thereof is incident inside the first portion 76, and the other part of the incident illumination light is reflected. That is, the illumination light is divided into transmitted light (solid line arrow in FIG. 6) and reflected light (broken line arrow in FIG. 6) on the inclined reflecting surface 76a.

Since the first portion 76 is formed of a light diffusing material, a part of the illumination light incident on the inside of the first portion 76 is diffused in various places inside the medium of the first portion 76. A diffusing action also occurs at the connecting portion 79. Since the diffused light is semi-transmitted through the smoke portion 73, it is visually recognized from the viewing side as if the first portion 76 and the connecting portion 79 are emitting light.

Here, the illumination light directly incident on the inclined reflection surface 76a from the irradiation region 44 will be described in more detail. Of the first portion 76 and the connection portion 79, the illumination of the portion overlapping the boundary between the irradiation region 44 and the regulation region 45, 46 is low because the illumination is regulated in the regulation region 45, 46. Further, the density of illumination may be lower on the outer peripheral side of the first portion 76 and the connection portion 79 that are far from the irradiation region 44. As a result, with respect to the directly incident illumination light, the density of illumination tends to decrease on the outer peripheral side of the first portion 76 and the connection portion 79.

On the other hand, the other portion of the reflected illumination light heads toward the first portion 76 according to the inclination direction of the inclined reflection surface 76a. Since the second portion 80 is also formed of the light diffusing material, the second portion 80 functions as a diffusing portion that diffuses the illumination light reflected on the inclined reflecting surface 76a by using the diffusing action of the light diffusing material. The illumination light is diffused in all directions at the second portion 80, but a relatively large amount of illumination light is incident on the outer peripheral side of the first portion 76 and the connection portion 79.

Further, although the surface of the second portion 80 is formed in a mirror surface shape, the diffusion function on the surface may be enhanced by forming the surface in a rough surface shape.

Therefore, the illumination light diffused by the second portion 80 supplements the illumination light directly incident from the irradiation region 44, so that the first portion 76 and the connection portion 79 are illuminated relatively uniformly from the inner peripheral side to the outer peripheral side. Will receive.

Further, as described above, since the first portion 76 is formed in a plate shape having a uniform thickness, the degree of diffusion and the degree of transmission of the illumination light from the inner peripheral side to the outer peripheral side are about the same. As a result, the light emitting main body 75 can be made to emit light with little uneven brightness.

In the abutting portion 78 in the present embodiment, the emission brightness is gradually reduced toward the inner peripheral side to realize gradation-like light emission.

Further, when the light emitting element 50a of the ring member light source unit 50 is turned off, such as when the power of the vehicle display device 100 is turned off, the smoke unit 73 hides the light emitting body 75, so that the milky white color of the light emitting body 75 is less noticeable. .. Further, since the light emitting main body 75 is milky white, it is possible to prevent the internal structure of the light guide prism member 60 and the like from being peeped through the irradiation region 44 and the like.

In the present embodiment, the light source unit 50 for the ring member, the light guide prism member 60, and the irradiation area 44 and the regulation area 46 of the display plate 40 form the "illumination unit", and the light emitting main unit 75 and the smoke unit 73 form. It constitutes a "light emitting unit".

(Action effect)
The effects of the present embodiment described above will be described again below.

According to the present embodiment, in the first portion 76 provided so as to overlap the irradiation region 44, among the light emitting main body portion 75 which is one component of the light emitting portion arranged so as to straddle the irradiation region 44 and the regulation region 46. , The inclined reflection surface 76a is provided. Therefore, the illumination light emitted from the irradiation region 44 of the display board 40, which is one component of the illumination unit, to the viewing side illuminates the first portion 76 that overlaps with the irradiation region 44, and at that time, the first portion 76 is illuminated. It also incidents on the inclined reflection surface 76a provided at the portion 76. Here, since the inclined reflection surface 76a is inclined so as to move away from the display plate 40 from the irradiation region 44 side toward the regulation region 46 side, the illumination light from the irradiation region 44 is reflected toward the regulation region 46 side. Therefore, the illumination light reaches the portion overlapping the regulated area 46.

Here, the light emitting main body portion 75 functions as a diffusing portion in the second portion 80 provided so as to overlap the regulation region 46. The second portion 80, which functions as a diffusing portion, diffuses the illumination light reflected on the inclined reflecting surface 76a, so that the second portion 80 can also emit light to the viewing side. As a result, the light is sufficiently brightly emitted even in the portion of the light emitting portion that overlaps with the regulation region 46. As described above, it is possible to provide the vehicle display device 100 having a good appearance.

Further, according to the present embodiment, the inclined reflecting surface 76a forms a surface facing the irradiation region 44 in the first portion 76 formed of the light diffusing material that diffuses the illumination light. By doing so, while a part of the illumination light incident on the first part 76 from the irradiation area 44 is reflected toward the second part 80 side, the other part is diffused inside the first part 76, so that the light emitting main body Even in the portion 75 that overlaps with the irradiation region 44, light can be sufficiently brightly emitted. Since each part of the light emitting main body 75 emits bright light, the appearance is further improved.

Further, according to the present embodiment, the first portion 76 is formed in a plate shape having a uniform thickness along the inclined reflecting surface 76a. By forming the light diffusing material into a plate shape having a uniform thickness, it is possible to suppress the occurrence of unevenness of light and darkness between each portion of the first portion 76, and the brightness is homogenized. Therefore, it looks even better.

Further, according to the present embodiment, the second part 80 is integrally formed with the first part 76 by the light diffusing material, and the second part 80 functioning as a diffusing part uses the diffusing action of the light diffusing material. Diffuses the illumination light. In this way, it is possible to realize the first portion 76 having both the reflective action and the diffusing action and the second part 80 having the diffusing action with a simple one-part configuration, so that the appearance effect can be easily enhanced. be able to.

Further, according to the present embodiment, since the dark smoked portion 73 that semi-transmits the illumination light covers the entire first portion 76 and the second portion 80 from the viewing side, it looks good when the light emitting body emits light. The light emitting effect can be realized, and the appearance can be improved by not directly visually recognizing the light emitting main body 75 when the light is not emitted.

Further, according to the present embodiment, the light emitting portion is on the visual side as it goes from the inner peripheral side to the outer peripheral side in accordance with the inclined reflecting surface 76a that inclines so as to move away from the illuminating portion. It protrudes to. Here, the outer peripheral side of the annular light emitting portion that protrudes most to the visible side emits bright light due to the diffusing action of the inclined reflecting surface 76a and the second portion 80, so that the brightness and the three-dimensional effect are combined to make the appearance look good. Is significantly better.

Further, according to the present embodiment, the light guide prism member 60 guides the illumination light emitted from the light emitting element 50a, and the display plate 40 as a plate-shaped member is emitted from the lead-out surface 64 of the light guide prism member 60. The illumination light is transmitted in the irradiation region 44. In this way, since the range of the irradiation area 44 can be adjusted by the display board 40, the quality and brightness of the illumination are appropriately balanced, and the appearance is remarkably good.
