  As shown in FIGS. 1 and 2, the vehicle display device 1 according to the first embodiment is disposed above a dashboard 101 of a vehicle. The vehicle display device 1 of the present embodiment is a meter device that displays information including a vehicle state such as a running speed of a vehicle, and is disposed in front of a driver 106 (for example, a head of the driver 106). The vehicle display device 1 is located, for example, in front of the steering wheel 103 when viewed from the driver 106. The upper part of the vehicle display device 1 is covered by a cover part 102 from above. In this specification, the “vertical direction” indicates the vertical direction of the vehicle on which the vehicle display device 1 is mounted. The “vehicle width direction” indicates the vehicle width direction of the vehicle on which the vehicle display device 1 is mounted, and the “vehicle front-rear direction” indicates the vehicle front-rear direction of the vehicle. The vehicle display device 1 of the present embodiment is mounted on a vehicle such that an axial direction of a tubular member 2 described later coincides with a vehicle longitudinal direction.

  A portion of the dashboard 101 located in front of the driver 106 is provided with a recess 101a which is one step lower than the periphery. The vehicle display device 1 is arranged on the concave portion 101a. The recess 101a is provided with an opening. The vehicle display device 1 is fixed so as to close the opening. A power supply line and a signal line are connected to the vehicle display device 1 through the opening. The cover portion 102 is bridged over the space above the concave portion 101a, and is gently curved upward. The cover part 102 extends in the vehicle width direction, and both ends are connected to the dashboard 101, respectively.

  A tunnel-shaped space 105 extending in the vehicle front-rear direction is formed between the recess 101 a of the dashboard 101 and the cover 102. In the space 105, a rear end in the vehicle front-rear direction is open to the driver 106. The front end of the space 105 is open toward the windshield 104. An inclined surface 101b of the dashboard 101 exists in front of the space 105. The inclined surface 101b has an upward slope as it goes forward of the vehicle. The position of the upper end of the inclined surface 101b is set so that the driver 106 cannot directly see the scene outside the vehicle through the space 105. The position of the upper end of the inclined surface 101b is, for example, a position above the upper end of the vehicle display device 1.

  As shown in FIGS. 3 and 4, the vehicle display device 1 includes a tubular member 2, a projection unit 5, a half mirror 6, a design unit 3, a support unit 4, and a light source 7. The tubular member 2 is a hollow tubular member, and both ends are open. The tubular member 2 of the present embodiment has an elliptical cross section. The tubular member 2 is integrally formed of, for example, a synthetic resin. It is preferable that the cylindrical member 2 has a light shielding property. The tubular member 2 is mounted on the vehicle in a posture in which the short axis direction is the vertical direction. One open end 21 of the tubular member 2 is directed rearward. The other open end 22 of the tubular member 2 is directed forward.

  The tubular member 2 is arranged in the passenger compartment with one open end 21 facing the driver 106 side of the driver's seat and the other open end 22 facing the front of the vehicle. In the following description, the open end 21 of the tubular member 2 facing the driver 106 (driver's seat side) is referred to as a “rear open end 21”, and the open end 22 facing the front of the vehicle is referred to as a “front open end 22”. Called. As shown in FIG. 3, both ends of the tubular member 2 are inclined with respect to the vertical direction. The front open end 22 is inclined so as to go downward as it goes forward. The rear open end 21 is inclined so as to go downward as it goes backward.

  The tubular member 2 of the present embodiment is formed in a tapered shape in which the cross-sectional area decreases from the rear to the front. More specifically, the length of the short axis and the length of the long axis of the tubular member 2 become shorter from the rear to the front. Accordingly, when viewed from the driver 106 side, the depth of the tubular member 2 is felt longer than it actually is.

  The projection unit 5 projects an image toward the internal space of the tubular member 2. The projection unit 5 of the present embodiment is a liquid crystal display device, for example, a TFT-LCD (Thin Film Transistor-Liquid Crystal Display). The projection unit 5 is arranged above the tubular member 2. An opening 23 is provided in an upper part of the tubular member 2. The image display surface of the projection unit 5 is disposed in the opening 23 with the downward direction. That is, the projection unit 5 projects an image toward the internal space of the tubular member 2 via the opening 23. The projection unit 5 projects an image in a direction intersecting with the axial direction of the tubular member 2, typically in a direction orthogonal to the axial direction.

  The half mirror 6 is a semi-permeable member arranged in the internal space of the tubular member 2. The half mirror 6 reflects a part of the incident light and transmits another part of the incident light. The half mirror 6 has a main body formed of a transparent resin, glass, or the like, and a half mirror layer. The half mirror layer is a metal or inorganic multilayer thin film formed on the surface of the main body by vapor deposition or the like. The half mirror 6 is an elliptical plate-shaped member, and partitions the internal space of the cylindrical member 2 into a front space portion and a rear space portion. The half mirror 6 is arranged to be inclined so as to face the projection unit 5. The half mirror 6 is inclined so as to go backward as it goes downward. The half mirror 6 reflects an image projected downward from the projection unit 5 toward the driver 106, and displays the image as a virtual image. Due to the image reflected by the half mirror 6, a virtual image is formed ahead of the half mirror 6. The vehicle display device 1 of the present embodiment is configured such that a virtual image is formed in the internal space of the tubular member 2, in other words, the focal position of the virtual image is located in the internal space of the tubular member 2. .

  The design part 3 is a three-dimensional design member having a three-dimensional shape. The design part 3 is arranged on the side opposite to the driver 106 side of the half mirror 6 in the internal space of the tubular member 2. The shape of the design part 3 of the first embodiment is a spherical shape. The design part 3 is a plate-shaped member curved in a spherical shape toward the driver 106 side. In other words, the shape of the design part 3 is a shape in which a part of a hollow spherical shape is cut out by a plane. The design part 3 of the present embodiment is formed of a transparent or translucent material such as synthetic resin or glass. The design part 3 is arranged coaxially with the central axis of the tubular member 2.

  The support portion 4 supports the design portion 3 by being interposed between the tubular member 2 and the design portion 3. The support portion 4 allows light to pass between the rear open end 21 and the front open end 22 of the tubular member 2. The support portion 4 of the present embodiment is a transparent plate-shaped member, and is formed of, for example, a synthetic resin. That is, the support portion 4 is a member that allows light to pass therethrough, and allows light to pass through the internal space of the tubular member 2 from the rear open end 21 to the front open end 22. Is allowed to pass through the internal space from the front open end 22 to the rear open end 21. The shape of the support portion 4 is an elliptical shape corresponding to the cross-sectional shape of the tubular member 2. The outer edge of the support 4 is fixed to the inner wall surface of the tubular member 2. The support portion 4 is arranged so as to be orthogonal to the central axis of the tubular member 2 and partitions the internal space of the tubular member 2 into a front space portion and a rear space portion. The design part 3 is fixed to a surface 4 a of the support part 4 on the driver 106 side. The method of fixing the design part 3 to the support part 4 is, for example, adhesion or welding.

  The surface of the support 4 is subjected to a process for suppressing light reflection. The support portion 4 of the present embodiment has an AR coating process on both surfaces. Thus, reflection of light on the surface of the support 4 is prevented, and the presence of the support 4 is hardly seen by the driver 106.

  The light source 7 is a light emitting unit such as an LED, and emits light toward the internal space of the tubular member 2. The light source 7 is arranged between the half mirror 6 and the design part 3. A depression 24 is provided on the lower inner wall surface of the tubular member 2. The light source 7 is arranged in the depression 24. The light source 7 emits light obliquely upward so as to illuminate a space ahead of the half mirror 6. The light source 7 illuminates the design portion 3 by, for example, irradiating light toward the design portion 3. Part of the light emitted from the light source 7 is reflected by the design part 3 toward the driver 106. The reflected light makes it easier for the driver 106 to recognize the presence of the design portion 3 and the shape of the design portion 3.

  As shown in FIG. 5, a virtual image 10 is displayed in the internal space of the tubular member 2. The virtual image 10 of the present embodiment includes a battery information image 11, a power information image 12, an index image 13, a center display image 14, a fuel information image 15, and a water temperature information image 16. The battery information image 11 is an image that displays the remaining charge of the battery mounted on the vehicle. The power information image 12 is an image that displays information regarding the output power of the vehicle. The index image 13 includes scale images 13a and 13b and a numerical image 13c corresponding to the scale. The index image 13 of the present embodiment is an index of the engine rotation speed of the engine mounted on the vehicle. The index images 13 are arranged at predetermined intervals in the circumferential direction so as to surround the design portion 3. Although not shown in FIG. 5, the virtual image 10 further includes a pointer image. The pointer image is displayed at a position in the scale image 13b indicating the scale image 13b corresponding to the current engine rotation speed.

  The center display image 14 is an image displayed so as to overlap with the design part 3. As shown in FIG. 5, the center display image 14 is displayed so as to overlap the design part 3 when viewed in the axial direction of the tubular member 2. That is, the center display image 14 appears to the driver 106 so as to overlap the design part 3. The center display image 14 includes a speed image 14a that displays the running speed of the vehicle as a numerical value, and a shift position image 14b that displays the shift position of the vehicle. The fuel information image 15 is an image that displays the remaining fuel amount of the vehicle. The water temperature information image 16 is an image that displays the engine water temperature. In the present embodiment, the center display image 14 is displayed at the center, and the index image 13 is displayed outside the center display image 14. A battery information image 11 and a power information image 12 are displayed on the left side of the index image 13 as viewed from the driver 106. A fuel information image 15 and a water temperature information image 16 are displayed on the right side of the index image 13 as viewed from the driver 106.

  FIG. 3 shows a position P1 at which the virtual image 10 forms an image (hereinafter, simply referred to as “image forming position P1”). The imaging position P1 is the same position as the rear end 31 of the design portion 3 in the axial direction of the tubular member 2, or substantially the same position as the rear end 31. In the present embodiment, the image forming position P1 is a position slightly closer to the driver 106 than the rear end 31 of the design portion 3. With the image forming position P1 set in this way, the driver 106 looks as if the center display image 14 is displayed on the surface of the design portion 3. Therefore, the vehicle display device 1 of the present embodiment can perform a display with a three-dimensional effect by the combination of the three-dimensional design part 3 and the virtual image 10. The virtual image 10 formed at the image forming position P1 and the design part 3 having a three-dimensional shape with a depth are combined to form a design. This makes it easier for the driver 106 to recognize the depth of the internal space of the tubular member 2 in the depth direction.

  Further, since the virtual image 10 is displayed so as to be superimposed on the spherical surface of the design portion 3, it looks as if the virtual image 10 is projected on the spherical display surface. That is, the virtual image 10 looks like a round along the spherical surface of the design portion 3, and a display with a three-dimensional effect is obtained.

  Further, in the vehicle display device 1 of the present embodiment, the front open end 22 of the tubular member 2 is open. Therefore, the driver 106 can see the background behind the virtual image 10 and the design part 3. The background is, for example, the inclined surface 101b of the dashboard 101. When the inclined surface 101b illuminated by external light or the like is seen behind the virtual image 10 and the design portion 3, the driver 106 feels the presence of the space behind the tubular member 2. That is, the vehicular display device 1 realizes a meter having a three-dimensional effect by a combination of the virtual image 10, the design part 3, and the background. In other words, it can be said that the inclined surface 101b of the background forms a part of the meter design. Further, since the reflection suppressing process is performed on the support portion 4, the driver 106 looks as if the design portion 3 is floating in the air. The driver 106 has no member between the design part 3 and the inner wall surface of the tubular member 2, and the driver 106 is configured so that the rear open end 21 to the front open end 22 of the tubular member 2 communicate with each other. felt. Therefore, the driver 106 looks as if the virtual image 10 or the design part 3 is floating in front of the background, and feels a sense of unity between the background and the virtual image 10 or the design part 3.

  The tubular member 2 of the present embodiment is inclined such that the rear open end 21 faces obliquely upward. Accordingly, light in the vehicle compartment is easily inserted into the internal space of the tubular member 2. The light inserted into the cylindrical member 2 illuminates the inner wall surface of the cylindrical member 2, so that a depth and a three-dimensional effect can be felt in the internal space of the cylindrical member 2. In addition, the design part 3 reflects the light that enters the cylindrical member 2 toward the driver 106, so that the three-dimensional effect of the design part 3 is felt more strongly.

  The front open end 22 of the tubular member 2 is inclined so as to face diagonally upward. In other words, the opening of the front open end 22 faces the windshield 104. Therefore, external light can easily enter the internal space of the tubular member 2 from the front open end 22. In addition, since the front open end 22 is inclined, the cylindrical member 2 is less likely to block light traveling toward the inclined surface 101b of the dashboard 101. Therefore, the backgrounds of the design portion 3 and the virtual image 10 are not easily darkened. Therefore, the vehicle display device 1 of the present embodiment can realize a three-dimensional display by making the background easily visible from the driver 106.

  As described above, the vehicle display device 1 of the present embodiment includes the tubular member 2, the projection unit 5, the half mirror 6, the design unit 3, and the support unit 4. The support portion 4 is configured to allow light to pass between the front open end 22 and the rear open end 21 of the tubular member 2. On the back side of the virtual image 10 and the design part 3, an inclined surface 101b illuminated by external light is arranged as a background of the virtual image 10 and the design part 3. In addition to the virtual image 10 and the design part 3 displayed by the projection unit 5 and the half mirror 6, the occupant (typically, the driver 106) has a background (tilted side) opposite to the occupant side with respect to the tubular member 2. The surface 101b) is visible. Therefore, the vehicular display device 1 of the present embodiment can perform a three-dimensional display in which the virtual image 10, the design part 3, and the background overlap.

  The vehicle display device 1 according to the present embodiment includes a light source 7 that is disposed between the half mirror 6 and the design portion 3 and irradiates light to the design portion 3 to illuminate the design portion 3. Therefore, the passenger can easily recognize the existence of the design part 3 and the shape of the design part 3.

  At least a part of the virtual image 10 is displayed so as to overlap with the design part 3 when viewed in the axial direction of the tubular member 2. Therefore, a three-dimensional effect is produced by the combination of the virtual image 10 and the design part 3.

  Further, the support portion 4 is a transparent plate-shaped member, and connects the design portion 3 and the inner wall surface of the tubular member 2. Since the support portion 4 is a transparent plate-shaped member, the occupant can see the background of the design portion 3 and the virtual image 10 through the support portion 4. Therefore, except for the design part 3 and the virtual image 10, it is possible to make the passenger feel as if there is nothing obstructing the passenger to see the background.

  The surface of the support 4 is subjected to a process for suppressing light reflection. As a result, the support portion 4 becomes less noticeable than the design portion 3, and the support portion 4 is hardly recognized. Therefore, the vehicle display device 1 of the present embodiment can make the design part 3 look as if it is floating in the air. In the present embodiment, the processing for suppressing the reflection of light is performed on both surfaces of the support 4, but the processing may be performed on any one surface of the support 4. Further, it is also conceivable to use a support portion 4 that has not been subjected to a process for suppressing light reflection, such as when the support portion 4 is part of a design of a meter device. The supporting portion 4 may not be transparent as long as the supporting portion 4 has such a light transmitting property that the background can be seen from the driver 106.

[First Modification of First Embodiment]
A first modification of the first embodiment will be described. The imaging position P1 of the virtual image 10 is not limited to the position exemplified in the first embodiment. The imaging position P1 may be, for example, a position between the front end 32 and the rear end 31 of the design portion 3 in the axial direction of the tubular member 2. As shown in FIG. 3, the design portion 3 of the first embodiment has a flat front end 32. The front end 32 is fixed to the surface of the support 4 by welding, bonding, or the like. Since the imaging position P1 is a position between the front end 32 and the rear end 31 of the design part 3, the center display image 14 appears to be inside the design part 3 from the driver 106.

  The imaging position P1 is arbitrary, and may be a position in front of the design part 3 or a position behind the design part 3.

[Second Modification of First Embodiment]
A second modification of the first embodiment will be described. The shape of the center display image 14 may be a distorted shape imitating a case where an image is displayed on the surface of the design portion 3.

[Third Modification of First Embodiment]
A third modification of the first embodiment will be described. The shape of the design portion 3 is not limited to those illustrated in the first embodiment. For example, the design part 3 may be a solid member instead of a hollow member. The design part 3 may have a spherical shape not only on the rear side (the driver 106 side) but also on the front side. As an example, the shape of the design part 3 may be spherical, and the spherical design part 3 may be supported by the support part 4. In this case, the rear hemisphere of the design portion 3 may project rearward from the support portion 4, and the front hemisphere of the design portion 3 may project forward from the support portion 4.

[Second embodiment]
A second embodiment will be described with reference to FIGS. In the second embodiment, components having the same functions as those described in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted. 6 is a cross-sectional view of the vehicle display device according to the second embodiment, FIG. 7 is a front view of the vehicle display device according to the second embodiment, and FIG. 8 is a vehicle display device according to the second embodiment. It is a front view which shows the virtual image displayed by. FIG. 6 shows a section taken along line VI-VI of FIG. In the vehicle display device 1 of the second embodiment, a ring-shaped design portion 8 is provided instead of the design portion 3 of the first embodiment.

  The design part 8 is a ring-shaped member having a predetermined thickness. The design part 8 of the present embodiment has a light-shielding property, and is formed of, for example, metal or synthetic resin. The design part 8 is arranged coaxially with the central axis of the tubular member 2. As shown in FIG. 6, the front end 83 of the design part 8 is fixed to the support part 4 by adhesion, welding, or the like. The support part 4 is a transparent plate-shaped member like the support part 4 of the first embodiment. As shown in FIG. 7, a scale 82 is formed on an end face 81 behind the design portion 8. The scale 82 is a groove extending in the radial direction of the design portion 8. The scales 82 are arranged at predetermined intervals along the circumferential direction of the design portion 8. In the vehicle display device 1 according to the second embodiment, a part of the index image 13 according to the first embodiment is replaced with a scale 82 of the design part 8.

  The end face 81 of the design part 8 has an inclined part 81a. In the design portion 8 of the present embodiment, a half region on the radially inner side of the end face 81 is the inclined portion 81a. The inclined portion 81a is inclined so as to move forward (toward the rear as viewed from the driver 106) toward the inside in the radial direction. In the end face 81, a portion outside the inclined portion 81a is a flat portion 81b orthogonal to the axial direction of the tubular member 2. The inclined portion 81a gives the design portion 8 a three-dimensional effect. In addition, as can be seen from FIG. 7, the inclined portion 81a has a visual effect that makes the user feel the depth together with the inner wall surface of the tubular member 2.

  As shown in FIG. 8, the vehicle display device 1 according to the second embodiment displays a virtual image 10 substantially similar to the vehicle display device 1 according to the first embodiment. In the vehicle display device 1 of the present embodiment, the index image 13 and the center display image 14 are displayed in a region surrounded by the design portion 8. In the index image 13, the phase of the main scale of the scale image 13b and the phase of the numerical image 13c are matched with the phase of the scale 82 of the design part 8. Thus, a three-dimensional display is formed by a combination of a physically existing three-dimensional scale 82 and an index of the virtual image 10.

  As shown in FIG. 6, the image forming position P2 of the virtual image 10 in the vehicle display device 1 of the second embodiment is set at the rear end of the design portion 8. The rear end of the design portion 8 is a flat portion 81b on the end face 81 orthogonal to the axial direction. The position of the imaging position P2 is the same position as the plane portion 81b or substantially the same position as the plane portion 81b. In the present embodiment, the imaging position P2 is a position slightly closer to the driver 106 than the plane portion 81b. By setting the imaging position P2 in this way, the driver 106 looks as if the virtual image 10 is displayed on the same plane as the plane portion 81b of the design portion 8. Therefore, the vehicular display device 1 of the present embodiment can produce a three-dimensional effect by the combination of the three-dimensional design portion 8 and the virtual image 10. The virtual image 10 formed at the image forming position P2 and the design part 8 having a three-dimensional shape with a depth are combined to form a design. This makes it easier for the driver 106 to recognize the depth of the internal space of the tubular member 2 in the depth direction.

  Further, in the vehicle display device 1 of the second embodiment, the driver 106 can see through the support portion 4 to see the virtual image 10 and the background behind the design portion 8. Therefore, the vehicle display device 1 of the second embodiment realizes a meter with a three-dimensional effect by a combination of the virtual image 10, the design portion 8, and the background, similarly to the vehicle display device 1 of the first embodiment.

  In the vehicle display device 1 according to the second embodiment, at least a part of the virtual image 10 may be displayed so as to overlap the design part 8. For example, the index image 13 similar to that of the first embodiment may be displayed by overlapping the scale image 13a with the design portion 8. In this case, the design part 8 may not be provided with the scale 82.

[Modifications of the above embodiments]
Modifications of the first and second embodiments will be described. FIG. 9 is a front view showing a virtual image displayed by the vehicle display device according to the modified example of each embodiment. The virtual image 10 of the present modified example includes an index image 17 instead of the index image 13 of each of the above embodiments. The index image 17 is an image of a numerical index indicating the traveling speed of the vehicle. The types of indices of the index images 13 and 17 are not limited to those illustrated, but are arbitrary.

  The type, shape, arrangement, and the like of the images included in the virtual image 10 are not limited to those exemplified in the above embodiments. Further, the virtual image 10 may include another image in addition to or instead of the image of the information regarding the vehicle state and the like. For example, the virtual image 10 may include a navigation image, a television broadcast image, a video image, and the like.

  The vehicle display device 1 is not limited to a meter device that displays information about a vehicle state and the like. The vehicle display device 1 may be used, for example, as a center display or as another display device arranged in a vehicle cabin.

  The projection unit 5 may be provided below or beside the tubular member 2. The projection unit 5 only needs to be able to project an image, and is not limited to a liquid crystal display device.

  The vehicle display device 1 may have a plurality of design portions. For example, the vehicle display device 1 may have both the design part 3 of the first embodiment and the design part 8 of the second embodiment. Further, the plurality of design parts may be arranged at different positions along the axial direction of the tubular member 2.

  The vehicle display device 1 may include a light source that illuminates the background (hereinafter, referred to as a “second light source”). It is preferable that the second light source is disposed on the front side of the support part 4, that is, on the side opposite to the driver 106 side. The second light source irradiates light toward the background in an environment where the background is difficult to see from the driver 106, such as at night, for example. This makes it possible to produce a three-dimensional effect even at night or the like by displaying the background. It is preferable that the second light source is disposed above the tubular member 2 and emits light downward.

  The configuration and shape of the tubular member 2 are not limited to those illustrated. The tubular member 2 may be a combination of a plurality of components. As an example, the cylindrical member 2 may be a combination of semi-cylindrical components. The cross-sectional shape of the tubular member 2 may be a rectangle or another polygon.

  If the support portion 4 is configured to allow light to pass between the rear open end 21 (one open end) and the front open end 22 (the other open end) of the tubular member 2, It does not need to have translucency. For example, the support portion 4 may be a member having an opening or a notch that allows light to pass between the rear open end 21 and the front open end 22 of the tubular member 2. In this way, the driver 106 can see the backgrounds of the design portions 3 and 8 and the virtual image 10 through the opening and the cutout of the support portion 4. Alternatively, the support portion 4 may be a rod-shaped or column-shaped member that connects the design portions 3 and 8 and the inner wall surface of the tubular member 2.

  A background member different from the dashboard 101 may be provided as a background of the design portions 3 and 8 and the virtual image 10. The background member is disposed at a position separated from the front open end 22 of the tubular member 2 so as to face the front open end 22 in the axial direction.

  The contents disclosed in the above embodiments and modified examples can be appropriately combined and executed.
