[Embodiment]
An embodiment will be described with reference to FIGS. 1 to 4. The present embodiment relates to a vehicle display device. FIG. 1 is a diagram showing a vehicle display device according to an embodiment of the present invention. FIG. 2 is a plan view of the first display unit according to the embodiment. FIG. 3 is a sectional view taken along line III-III of FIG. FIG. 4 is a sectional view taken along line IV-IV of FIG.

The vehicle display device 1 according to the embodiment is mounted on the vehicle and displays information about the vehicle. As shown in FIG. 1, the vehicle display device 1 according to the embodiment is arranged on, for example, an instrument panel provided on the dashboard of the vehicle. The vehicle display device 1 is arranged so as to face the driver's seat of the vehicle. The vehicle display device 1 is located in front of the vehicle with respect to the driver seated in the driver's seat.

As shown in FIG. 1, the vehicle display device 1 includes a first display unit 10, a second display unit 20, and a multi-display unit 31 of a liquid crystal display device using a liquid crystal plate 61 (Liquid Crystal Display: LCD). A turn L display unit 32, a turn R display unit 33, a shift indicator 34, a TRIP knob 36, and a warning lamp 37 for not wearing a seatbelt or forgetting to turn off the headlamps 37 are provided.

For example, the first display unit 10 is a speedometer that displays the speed of the vehicle, and the second display unit 20 is a tachometer that displays the engine speed.

The first display unit 10, the second display unit 20, the multi-display unit 31, the turn L display unit 32, the turn R display unit 33, the shift indicator 34, the TRIP knob 36, and the warning lamp 37 are meters of the vehicle display device 1. It is housed in the case 70. A facing 38 is attached to the front of the meter case 70. The dial 38 hides the wiring, the drive unit, the substrate, and the like of the electronic components housed in the meter case 70. Further, a front glass is attached to the front side of the meter case 70.

An example of the configuration of the first display unit 10 will be described below.
As shown in FIG. 2, the first display unit 10 includes a dial 11 and a pointer 12.
Regarding the vehicle display device 1, the "depth direction" is a direction orthogonal to the front surface 11a of the dial 11 when mounted on the vehicle, and is typically a front-rear direction of the vehicle. The depth direction is the direction orthogonal to the paper surface in FIG. The relative front side of the vehicle in the depth direction is referred to as the "rear side", and the relative rear side of the vehicle is referred to as the "front side".

The dial 11 has a light-shielding property and contains, for example, a resin material. The dial 11 can be formed of, for example, a polycarbonate resin or an acrylic resin. For example, the dial 11 may be printed with dark-colored ink in which the shape corresponding to the index portion, the symbol for warning display, or the like is hollowed out. In this case, the vehicle display device 1 is provided with a dial light source that irradiates the dial 11 with light from the back side. In the dial 11, the hollow portion of the print transmits the light emitted from the light source for the dial. Therefore, when the light of the dial light source is applied to the hollow portion corresponding to the index portion, the index of the dial 11 emits light by the light. Further, when the light of the dial light source is applied to the hollow portion corresponding to the symbol for warning display, the symbol is displayed. On the other hand, in the dial 11, the area printed with ink blocks the light emitted from the dial light source. The printed area may emit light at a brightness lower than that of the index portion or the symbol portion, for example, as a background surrounding the index portion or the symbol portion.

On the dial 11 of the first display unit 10, for example, a scale line 11b and a number 11c as a sign of a traveling speed are arranged. A plurality of scale lines 11b and numbers 11c are arranged along the circumferential direction centered on the rotation center C1 of the pointer 12. The number 11c indicates the traveling speed corresponding to the scale line 11b. The pointer 12 is driven by a drive unit 19 described later to rotate, and points to a scale line 11b according to the current traveling speed. The dial 11 has a through hole 11d. The through hole 11d penetrates the dial 11 in the depth direction. The through hole 11d of the present embodiment has a circular shape in a plan view. The rotation center C1 of the pointer 12 is the central axis of the through hole 11d.

As shown in FIGS. 2 and 3, the pointer 12 includes a pointer body 13 and a connecting member 14. The pointer body 13 is arranged closer to the visual position 2 than the dial 11. For example, the pointer body 13 extends along one direction substantially parallel to the front surface 11a of the dial 11. The pointer body 13 is a rod-shaped or needle-shaped component, and includes a pointer light emitting body 15 and a shielding portion 16. The visual position 2 is a visual position where the occupant in the vehicle interior visually recognizes the vehicle display device 1, and is typically a visual position of the driver who is seated in the driver's seat.

The pointer light emitting body 15 emits light by light transmitted via the rotation shaft 19a described later. The pointer illuminant 15 is a translucent member that transmits light, and is, for example, a transparent synthetic resin member. The pointer illuminant 15 is connected to the connecting member 14 on the base end side in the length direction. The connecting member 14 is inserted through the through hole 11d. As shown in FIG. 3, the pointer illuminant 15 extends along one direction substantially parallel to the front surface 11a of the dial 11.

The shielding portion 16 is a light-shielding cover member that covers a part of the pointer illuminant 15 from the visual position 2 side, and exposes the other portion of the pointer illuminant 15. Seen from the visual position 2, the shielding portion 16 covers, for example, the through hole 11d and the connecting member 14. The through hole 11d and the connecting member 14 are covered by the shielding portion 16 so that they are not directly visible from the visual position 2. More specifically, the shielding portion 16 is a hollow case-shaped member having a slit 16b formed on the front surface 16a. The slit 16b extends along the length direction of the pointer body 13. The occupant in the vehicle interior can visually recognize the portion of the pointer illuminant 15 exposed from the slit 16b from the visual position 2.

The portion of the pointer illuminant 15 that is visible from the visual position 2, in other words, the portion of the pointer illuminant 15 that is exposed to the outside from the slit 16b of the shielding portion 16 is referred to as an exposed portion 15a. As shown in FIG. 3, the cross-sectional shape of the pointer illuminant 15 in the direction along the rotation center C1 is a tapered shape in which the width becomes narrower as the distance from the portion connected to the connecting member 14 toward the tip side increases. The back surface 15b of the exposed portion 15a is parallel to the dial 11. The front surface 15c of the exposed portion 15a is inclined so as to approach the dial 11 as the distance from the proximal end side connected to the connecting member 14 toward the distal end side increases.

As shown in FIGS. 3 and 4, the first display unit 10 includes a light source 3 and a drive unit 19. The light source 3 and the drive unit 19 are provided on the back side of the dial 11. The light source 3 is arranged at a position on the back side of the dial 11 and facing the through hole 11d. The light source 3 is composed of, for example, a light emitting diode (LED) element or the like, but is not limited to this. The light source 3 of the embodiment is held by the substrate 18. The substrate 18 is arranged on the back side of the dial 11 and holds the light source 3, the drive unit 19, the dial light source, and the like. The light source 3 emits light toward the through hole 11d side, that is, the front side.

The drive unit 19 is held by the substrate 18. The substrate 18 is provided on the back side of the dial 11, the light source 3, the drive unit 19, and the light source for the dial. The substrate 18 holds a light source 3, a drive unit 19, a light source for a dial, and the like. The drive unit 19 includes a rotating shaft 19a and a main body unit 19b. The drive unit 19 includes, for example, a drive source such as a motor in the main body unit 19b. The drive unit 19 rotates the rotating shaft 19a by the supplied electric power. The drive unit 19 adjusts the rotation position of the rotation shaft 19a according to the detected vehicle speed so that the pointer 12 points to the scale line 11b according to the vehicle speed.

The rotation shaft 19a is arranged on the back side of the dial 11. The rotation shaft 19a is located between the dial 11 and the light source 3. The rotating shaft 19a is a translucent member through which light is transmitted, and is, for example, a member made of synthetic resin. The rotating shaft 19a is arranged coaxially with the through hole 11d, and projects from the main body portion 19b of the drive unit 19 toward the through hole 11d. The rotating shaft 19a is rotatably supported by the main body 19b. The shape of the portion of the rotating shaft 19a protruding from the main body 19b is a cylindrical shape or a polygonal prism shape. The light source 3 faces the base end surface 19s of the rotation shaft 19a, and emits light from the light source 3 toward the base end surface 19s. The rotating shaft 19a functions as a light guide shaft that guides the light emitted from the light source 3 toward the pointer 12. That is, the light emitted from the light source 3 is incident on the end of the rotating shaft 19a on the light source 3 side. Then, the rotating shaft 19a guides the light incident on the rotating shaft 19a to the pointer 12 side on the front side and emits the light.

The connecting member 14 includes a first connecting portion 14a and a second connecting portion 14b. The first connecting portion 14a is inserted through the through hole 11d and connected to the rotating shaft 19a. The first connection portion 14a has a tubular shape. The first connection portion 14a of the present embodiment has a cylindrical shape. The rotating shaft 19a is inserted into the first connecting portion 14a so as not to rotate relative to the first connecting portion 14a. The rotating shaft 19a may be press-fitted into the first connecting portion 14a. The second connecting portion 14b is located between the shielding portion 16 and the dial 11, at least the outer peripheral surface 14s is exposed, and is connected to the pointer light emitting body 15. The second connecting portion 14b has a tubular shape. The second connecting portion 14b of the present embodiment has a cylindrical shape or an annular shape. The pointer illuminant 15 is connected to the second connecting portion 14b so as not to rotate relative to the second connecting portion 14b. In the present embodiment, the columnar shaft portion provided on the pointer light emitting body 15 is inserted into the second connecting portion 14b.

The first connection portion 14a and the second connection portion 14b are integrally formed, and the outer diameter of the first connection portion 14a is smaller than the outer diameter of the second connection portion 14b. For example, the outer diameter of the second connecting portion 14b is larger than the diameter of the through hole 11d. The central axis of the first connecting portion 14a and the central axis of the second connecting portion 14b are coaxial with each other. In the embodiment, the connecting member 14 is a tubular member in which two cylindrical constituent portions (first connecting portion 14a and second connecting portion 14b) having different outer diameters are connected along the depth direction. The first connecting portion 14a extends from the back side of the dial 11 to the front side of the dial 11. The second connecting portion 14b is separated from the front surface 11a of the dial 11 on the front surface side of the dial 11. Inside the connecting member 14, there is a space sp between the pointer light emitter 15 and the rotating shaft 19a. The space sp penetrates the connecting member 14 in the axial direction, and the connecting member 14 is hollow. In a state where the first connecting portion 14a of the connecting member 14 is inserted into the through hole 11d, the space sp penetrates the connecting member 14 in the depth direction. The cross-sectional shape of the space sp in the plane orthogonal to the depth direction is circular. In the present embodiment, the inner diameter of the connecting member 14 is substantially constant. The space sp is blocked by the pointer light emitter 15 and the rotation shaft 19a. The light emitted from the rotating shaft 19a is incident on the connecting member 14 or the pointer illuminant 15 via the space sp.

The connecting member 14 is a light diffusing portion 14D that diffuses light that has passed through the rotating shaft 19a, at least in part. In the present embodiment, the case where the entire connecting member 14 is the light diffusing portion 14D will be described as an example. The light diffusing unit 14D contains, for example, a resin containing a light diffusing agent 14p. The light diffusing portion 14D is formed by dispersing particles having a refractive index different from that of the transparent material as a light diffusing agent 14p in a transparent material containing, for example, glass, polycarbonate, polystyrene, acrylic resin, or the like. The light diffusing agent 14p is uniformly dispersed in the resin or substantially uniformly dispersed in the resin. The light diffusing portion 14D is formed as a milky white member having light diffusing property, for example, by molding a colorless and transparent resin to which white particles are added. The light diffusing portion 14D may be formed by dispersing the light diffusing agent 14p in a colored transparent resin containing a dye.

The optical paths of the light emitted from the light source 3 are shown by arrows Y1 to Y7 in FIGS. 3 and 4. As shown by the arrow Y1, the light emitted from the light source 3 passes through the rotation axis 19a. A part of the light passing through the rotating shaft 19a is incident on the connecting member 14 via the space sp as shown by the arrow Y2. The light incident on the connecting member 14 is diffused (diffused in various directions such as the circumferential direction and the radial direction of the connecting member 14) by the light diffusing agent 14p inside the light diffusing portion 14D as shown by the arrow Y3 in FIG. It is ejected from the connecting member 14. The light emitted from the connecting member 14 is reflected by the dial 11 around the connecting member 14 as leaked light as shown by the arrow Y4. Due to the reflected light (arrow Y4), the peripheral region of the connecting member 14 on the dial 11 is visually recognized brighter than the other regions of the dial 11. In other words, the light emitted from the connecting member 14 illuminates the periphery of the pointer 12 on the dial 11 in a ring shape. As a result, a visual effect or the like that makes the pointer 12 appear as a silhouette is generated. Therefore, the vehicle display device 1 of the present embodiment can effectively utilize the light of the light source 3 to improve the design.

Although not shown, another part of the light passing through the rotation axis 19a may be incident on the light diffusing portion 14D via the space sp and the pointer illuminant 15.

Further, as shown by an arrow Y5 in FIG. 3, a part of the light passing through the rotation axis 19a and the space sp is incident on the pointer light emitting body 15. The light incident on the pointer illuminant 15 passes through the inside of the pointer illuminant 15 as shown by an arrow Y6 in FIG. After that, the light that has passed through the inside of the pointer light emitting body 15 is emitted from the front surface 15c of the exposed portion 15a as shown by an arrow Y7 in FIG. That is, the exposed portion 15a of the pointer light emitting body 15 emits light by the light passing through the rotating shaft 19a, the space sp in the connecting member 14, and the inside of the pointer light emitting body 15.

As a configuration different from the present embodiment, it is conceivable that the connecting member 14 is provided as a member made of a transparent resin instead of the light diffusing portion 14D. When the connecting member 14 does not have the light diffusing portion 14D, the light emitted from the connecting member 14 may be locally focused due to the shape of the connecting member 14. The locally focused light illuminates the dial 11, causing uneven brightness.

On the other hand, in the present embodiment, the connecting member 14 is the light diffusing unit 14D, and the light is diffused by the light diffusing unit 14D. By diffusing the light by the light diffusing unit 14D, local condensing due to the shape of the connecting member 14 is suppressed. By suppressing the local focusing of the light emitted from the connecting member 14, for example, it is possible to suppress the uneven brightness of the leaked light that illuminates the peripheral region of the connecting member 14 on the dial 11.

As described above, the vehicle display device 1 according to the present embodiment includes a light source 3, a drive unit 19, a dial 11, and a pointer 12. The drive unit 19 includes a rotating shaft 19a that guides light from the light source 3. The dial 11 is arranged closer to the visual position 2 than the light source 3 and the drive unit 19, has a light-shielding property, and has a through hole 11d. At least a part of the pointer 12 is arranged closer to the visual position 2 than the dial 11.

The pointer 12 includes a connecting member 14, a pointer illuminant 15, and a shielding portion 16. The connecting member 14 is a light diffusing portion 14D that diffuses light at least in part through the rotating shaft 19a. The connecting member 14 has translucency. The pointer light emitting body 15 is arranged closer to the visual position 2 than the dial 11 and the connecting member 14, and emits light by light passing through the rotating shaft 19a and the through hole 11d. The shielding portion 16 covers a part of the pointer light emitting body 15 from the visual position 2 side, and shields the through hole 11d and the connecting member 14 from the visual position 2.

The connecting member 14 includes a first connecting portion 14a and a second connecting portion 14b. The first connecting portion 14a is inserted through the through hole 11d and connected to the rotating shaft 19a. The second connecting portion 14b is located between the shielding portion 16 and the dial 11, at least the outer peripheral surface 14s is exposed, and is connected to the pointer light emitting body 15. In the vehicle display device 1 according to the present embodiment, since the connecting member 14 has translucency, the light emitted from the light source 3 can illuminate the dial 11 via the connecting member 14. By illuminating the dial 11 with light (leakage light) passing through the connecting member 14, the design of the vehicle display device 1 can be improved.

In the vehicle display device 1 according to the present embodiment, since at least a part of the connecting member 14 is the light diffusing portion 14D, it is possible to suppress the local focusing of the light transmitted through the connecting member 14. By suppressing the local focusing of light, the uneven brightness of the leaked light is suppressed. By suppressing the uneven brightness of the leaked light, the design of the vehicle display device 1 can be improved.

Further, in the vehicle display device 1 of the present embodiment, the light diffusing unit 14D contains a resin containing a light diffusing agent 14p.

Further, in the vehicle display device 1 of the present embodiment, the light diffusing portion 14D is a portion including at least the outer peripheral surface 14s of the second connecting portion 14b. In the vehicle display device 1 according to the present embodiment, the leaked light is mainly emitted from the outer peripheral surface 14s of the second connecting portion 14b. By forming the portion where the leaked light is mainly emitted as the light diffusing portion 14D, it is possible to suppress the uneven brightness of the leaked light. By suppressing the uneven brightness of the leaked light, the design of the vehicle display device 1 can be improved.

When the distance between the second connecting portion 14b and the dial 11 is wide, the back surface (back surface 14u) of the second connecting portion 14b and the characters are shown by arrows Y3 in FIGS. 3 and 4. Light emitted from the outer peripheral surface 14g of the first connecting portion 14a located on the visual position 2 side of the plate 11 may also illuminate the dial 11 as leaking light. In the present embodiment, since the entire connecting member 14 is the light diffusing portion 14D, it is possible to suppress uneven brightness of the leaked light emitted from the back surface 14u and the outer peripheral surface 14g of the first connecting portion 14a.

The rotating shaft 19a is typically an output shaft of a motor provided in the drive unit 19, but is not limited thereto. The rotary shaft 19a is a shaft that rotates by the torque generated by the drive source. For example, even if the rotary shaft 19a is provided on a shaft separate from the output shaft of the motor and is rotationally driven by the motor via a gear mechanism or the like. Good.

In the present embodiment, the first display unit 10 has been described as an example, but for example, the above-described configuration may be applied to the second display unit 20. When the above-described configuration is applied to the second display unit 20, for example, the scale line arranged on the dial is a sign of the engine speed. The numbers placed on the dial indicate the engine speed corresponding to the scale line. The pointer is driven by the drive unit to rotate and points to a scale line according to the current engine speed.

[First Modified Example of Embodiment]
A first modification of the embodiment will be described.
FIG. 5 is a cross-sectional view of a guideline according to the first modification of the embodiment. FIG. 5 corresponds to FIG. 4 of the above embodiment.

The vehicle display device 1 of the first modification is different from the vehicle display device 1 of the above embodiment, for example, the first connection portion 14a has a light diffusing portion 14T having a lower light diffusing property than the light diffusing portion 14D. The point is that the second connecting portion 14b is a light diffusing portion 14D having a light diffusing property. As shown by the arrow Y1 in FIG. 5, the light emitted from the light source 3 passes through the rotation axis 19a. The translucent portion 14T has translucency and transmits the light emitted from the light source 3. A part of the light transmitted through the rotating shaft 19a reaches the light diffusing unit 14D via the light transmitting unit 14T. As shown by the arrow Y3, the light is diffused by the light diffusing unit 14D and emitted from the light diffusing unit 14D. The light emitted from the light diffusing unit 14D is reflected in the peripheral region of the connecting member 14 on the dial 11, as shown by the arrow Y4. Due to the reflected light (arrow Y4), the peripheral region of the connecting member 14 on the dial 11 is visually recognized brighter than the other regions of the dial 11.

Although not shown, another part of the light passing through the rotation axis 19a may be incident on the light diffusing portion 14D via the space sp and the pointer illuminant 15.

In this modification, the translucent portion 14T does not contain the light diffusing agent 14p. However, the translucent portion 14T may contain the light diffusing agent 14p. In this case, the volume content of the light diffusing agent 14p in the translucent portion 14T is the volume content of the light diffusing agent 14p in the light diffusing portion 14D. Lower than. For example, the translucent portion 14T contains a colorless transparent resin or a colored transparent resin.

In the connecting member 14 of the first modification, for example, the first connecting portion 14a (translucent portion 14T) and the second connecting portion 14b (light diffusing portion 14D) are integrally formed by a molding method such as so-called two-color molding. It is formed.

According to the vehicle display device 1 of the first modification, at least the second connection portion 14b is a light diffusing portion 14D having a light diffusing property, so that uneven brightness of the leaked light is suppressed. Most of the light emitted from the light source 3 and incident on the connecting member 14 is emitted as light leaking from the second connecting portion 14b to the dial 11. Even when the entire connecting member 14 is not used as the light diffusing portion 14D, the design of the vehicle display device 1 can be improved by mainly using the light diffusing portion 14D as the portion where the leaked light is emitted.

[Second variant of the embodiment]
A second modification of the embodiment will be described.
FIG. 6 is a cross-sectional view of a guideline according to a second modification of the embodiment. FIG. 6 corresponds to FIG. 4 of the above embodiment.

The vehicle display device 1 of the second modification is different from the vehicle display device 1 of the above embodiment, for example, a part including the outer peripheral surface 14s of the second connection portion 14b is a light diffusing portion 14D. The point is that the first connecting portion 14a and the other portion of the second connecting portion 14b are transmissive portions 14T having lower light diffusivity than the light diffusing portion 14D. The light diffusing portion 14D of the second modification has a cylindrical shape in which the length (thickness in the radial direction) between the outer peripheral surface and the inner peripheral surface is substantially uniform. That is, the radial outer portion of the second connecting portion 14b is the light diffusing portion 14D, and the radial inner portion of the second connecting portion 14b is the translucent portion 14T. As shown by arrows Y1 and Y2 in FIG. 6, the translucent portion 14T transmits light emitted from the light source 3 and passing through the rotation shaft 19a. The light reaches the light diffusing section 14D via the translucent section 14T. As shown by the arrow Y3, the light is diffused by the light diffusing portion 14D and emitted from the outer peripheral surface 14s or the like. The light emitted from the outer peripheral surface 14s is reflected by the peripheral region of the connecting member 14 on the dial 11, as indicated by the arrow Y4. Due to the reflected light (arrow Y4), the peripheral region of the connecting member 14 on the dial 11 is visually recognized brighter than the other regions of the dial 11.

Similar to the first modification, the connection member 14 of the second modification is integrally formed with the light diffusing portion 14D and the light transmitting portion 14T by, for example, a molding method such as so-called two-color molding. In the connecting member 14 of the second modification, for example, after forming the light transmitting portion 14T, a light diffusing paint is applied to the portion including the outer peripheral surface 14s of the second connecting portion 14b, whereby the light diffusing portion 14D May be provided.

For example, depending on the distance between the second connecting portion 14b and the dial 11, the leaked light emitted from the facing surface (rear surface 14u) of the second connecting portion 14b with the dial 11 may be almost invisible. .. In such a case, if the portion exposed to the outside of the second connecting portion 14b (the portion including the outer peripheral surface 14s of the second connecting portion 14b) is the light diffusing portion 14D, the effect of suppressing the uneven brightness of the leaked light is sufficient. Can be obtained.
