[Embodiment]
The embodiment will be described with reference to FIGS. 1 to 11. The present embodiment relates to a vehicle display device. 1 is a plan view of a display device for a vehicle according to an embodiment, FIG. 2 is a plan view of a display unit according to the embodiment, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG. FIG. 4 is a cross-sectional view of the connection member according to the embodiment, and FIG. 5 is a cross-sectional view of the vehicle display device according to the embodiment in a direction perpendicular to the rotation center. FIG. 6 is an enlarged cross-sectional view in the direction along the rotation center of the vehicle display device according to the embodiment.

  The vehicle display device 1 according to the embodiment is mounted on a vehicle and displays information related to the vehicle. The display device 1 for vehicles is arrange | positioned at the instrument panel provided in the dashboard of the vehicle, for example. The vehicle display device 1 of the present embodiment is disposed to face the driver's seat of the vehicle, and is located in front of the vehicle with respect to the driver seated in the driver's seat. The vehicle display device 1 includes a display unit 10 and a frame unit 20. The display unit 10 includes a dial plate 11 and a pointer 12.

  In the vehicle display device 1, the “width direction” is a lateral direction of the frame portion 20 in a state of being mounted on the vehicle, and is typically a vehicle width direction of the vehicle. In the vehicle display device 1, the “height direction” is a vertical direction of the frame portion 20 in a state of being mounted on a vehicle, and is typically a vertical direction. In the vehicle display device 1, the “depth direction” is the axial direction of the rotating shaft of the pointer 12 when mounted on the vehicle, and is typically the front-rear direction of the vehicle. The depth direction is a direction orthogonal to the paper surface in FIG. A relative vehicle front side in the depth direction is referred to as a “back side”, and a relative vehicle rear side is referred to as a “front side”.

  The frame part 20 has a facing plate 21 and a fixing part 22. The facing plate 21 has a surrounding surface 23 and a standing surface 24 surrounding each display unit 10. The standing surface 24 is provided at an edge of the enclosure surface 23 and surrounds the enclosure surface 23. The standing surface 24 protrudes from the enclosure surface 23 toward the front side in the depth direction. The standing surface 24 of the present embodiment has an opening cross-sectional area that increases toward the near side in the depth direction. The fixing portion 22 is provided on the outer surface of the standing surface 24 and includes a lock mechanism and an attachment hole. The fixing portion 22 is fixed at a predetermined position on the vehicle side by a locking mechanism or a fastening member such as a screw.

  The surrounding surface 23 is a plate-shaped component. The shape of the surrounding surface 23 is substantially rectangular, and the width direction is the longitudinal direction. Three display parts (left display part 10A, central display part 10B, and right display part 10C) are arranged on the surrounding surface 23 along the width direction. Each display unit 10 has a dial 11 and a pointer 12. The central display unit 10B displays the traveling speed of the vehicle. The information displayed by the display unit 10 includes the output speed of a power source such as an engine, an accumulated travel distance, a warning display, a shift position, and the like in addition to the travel speed. Below, the structure of the display part 10 is demonstrated taking the center display part 10B as an example.

  A hole 23 a corresponding to the central display portion 10 </ b> B is formed in the central portion of the surrounding surface 23. The hole 23a penetrates the enclosure surface 23 in the depth direction. The dial 11 of the central display unit 10B is exposed from the hole 23a. The front surface 11a of the dial plate 11 is a surface on the front side of the dial plate 11, and is a surface that is visually recognized by passengers including the driver. In other words, the front surface 11a of the dial 11 is a surface facing the viewing position. The visual position is a visual position where an occupant in the vehicle cabin visually recognizes the vehicle display device 1, and is typically a visual position of a driver seated in the driver's seat.

  The dial plate 11 is, for example, a polycarbonate sheet made of transparent fabric. The dial plate 11 is printed with a dark color ink in which a shape corresponding to an indicator portion, a warning display pattern, or the like is hollowed out. The vehicle display device 1 includes a dial light source that irradiates the dial 11 with light from the back side. In the dial 11, the printing hollow portion transmits light emitted from the dial light source. Therefore, when the light from the dial light source is irradiated to the hollow portion corresponding to the index, the index of the dial 11 is emitted by the light. Further, when the light of the dial light source is irradiated to the hollow portion corresponding to the symbol for warning display or the like, the symbol is displayed. On the other hand, in the dial plate 11, an area printed with ink blocks light emitted from the dial plate light source. For example, the printed area may emit light with a lower brightness than the index portion or the symbol portion as a background surrounding the index portion or the symbol.

  On the dial plate 11 of the central display unit 10B, a scale line 11b and a number 11c are arranged as indicators of the running speed. The dial 11 is printed with a hollow shape corresponding to the scale lines 11b and the numbers 11c. A plurality of the scale lines 11b and the numbers 11c are arranged along the circumferential direction around the rotation center C1 of the pointer 12. The numeral 11c indicates the traveling speed corresponding to the scale line 11b. The pointer 12 is driven and rotated by a motor 30 described later, and indicates a scale line 11b corresponding to the current traveling speed.

  As shown in FIGS. 2 and 3, the pointer 12 has a pointer main body 13 and a rotating shaft 14. As shown in FIG. 3, the pointer main body 13 is disposed closer to the viewing position 2 than the dial 11. The pointer main body 13 is a rod-shaped or needle-shaped component, and includes a pointer light emitter 15 and a pointer cover 16. The pointer light emitter 15 emits light by light transmitted via the rotating shaft 14. The pointer light emitter 15 is a translucent member that transmits light, for example, a transparent synthetic resin member. As shown in FIG. 3, the pointer light emitter 15 extends in a direction orthogonal to the rotation center C <b> 1 of the pointer 12. The rotation center C1 of the pointer 12 is the central axis of the rotation shaft 14.

  The pointer cover 16 is a light-shielding cover member that covers the pointer light emitter 15 and exposes part of the pointer light emitter 15. More specifically, the pointer cover 16 is a hollow case-shaped member having a slit 16b formed in the front surface 16a. The slit 16 b extends along the length direction of the pointer main body 13. An occupant in the vehicle compartment can visually recognize a portion exposed from the slit 16 b in the pointer light emitter 15 from the visual position 2. The pointer light emitter 15 is connected to the rotary shaft 14 at the base end side in the length direction.

  As shown in FIG. 3, the dial plate 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 plan view. The rotating shaft 14 is inserted into the through hole 11d and transmits light. In the pointer 12 of the present embodiment, the pointer light emitter 15 and the rotating shaft 14 are integrally formed. The rotating shaft 14 is a cylindrical or polygonal component, and protrudes from the pointer light emitter 15 toward the back side in the depth direction. The tip of the rotating shaft 14 is located on the back side of the dial 11. The pointer cover 16 includes a shaft cover portion 16c that covers the proximal end side of the rotating shaft 14, that is, the pointer light emitter 15 side. The shaft cover portion 16c has a cylindrical shape and protrudes toward the back side in the depth direction. The shaft cover portion 16 c of the present embodiment protrudes at least to the back side from the dial 11. Therefore, the shaft cover portion 16 c is inserted through the through hole 11 d together with the rotating shaft 14.

  In the pointer light emitter 15, a portion visually recognized from the visual position 2, in other words, a portion exposed to the outside in the slit 16 b of the pointer cover 16 is referred to as an exposed portion 15 a. As shown in FIG. 3, the cross-sectional shape of the pointer light emitter 15 in the direction along the rotation center C <b> 1 is a tapered shape in which the width becomes narrower as it moves away from the rotation shaft 14 toward the distal end side. The back surface 15 b of the exposed portion 15 a is parallel to the dial 11. The front surface 15c of the exposed portion 15a is inclined so as to approach the dial plate 11 as it moves away from the rotating shaft 14 toward the front end side. An inclined portion 15 d is provided at the base end portion of the pointer light emitter 15. The inclined portion 15d is located on the extension line of the rotating shaft 14. The inclined portion 15d is inclined in a direction in which light traveling from the rotating shaft 14 toward the front side is reflected toward the exposed portion 15a. That is, the inclined portion 15d is inclined so as to approach the dial plate 11 as it moves away from the exposed portion 15a toward the base end side.

  The central display unit 10B has a light source 3 such as an LED. The light source 3 is disposed on the back side of the dial 11. The light source 3 of this embodiment is held by the substrate 18. The substrate 18 is connected to the rear side of the dial plate 11 with respect to the frame portion 20, and holds the light source 3, the motor 30, the light source for the dial plate, and the like. The light source 3 is disposed at a position facing the through hole 11d in the substrate 18 and irradiates light toward the through hole 11d side, that is, the front surface side. The motor 30 is held by the substrate 18. The motor 30 has a drive shaft 31 and a main body 32, and rotates the drive shaft 31 with supplied electric power. The motor 30 adjusts the rotational position of the drive shaft 31 in accordance with the detected vehicle speed so that the pointer 12 points to the scale line 11b corresponding to the vehicle speed.

  The drive shaft 31 is disposed on the back side of the dial 11, that is, on the light source 3 side. The drive shaft 31 is a translucent member that transmits light, and is, for example, a transparent synthetic resin member. The drive shaft 31 is arranged coaxially with the through hole 11d and protrudes from the main body 32 of the motor 30 toward the through hole 11d. The drive shaft 31 is rotatably supported by the main body 32. In the drive shaft 31, the shape of the portion protruding from the main body 32 is a columnar shape or a polygonal column shape. The light source 3 faces the base end surface 31a of the drive shaft 31, and irradiates light toward the base end surface 31a.

  The connection member 5 is a light-shielding member that is disposed closer to the light source 3 than the dial 11 and connects the drive shaft 31 and the rotary shaft 14. The shape of the connection member 5 of this embodiment is a cylindrical shape. As shown in FIGS. 3 and 4, the connecting member 5 includes a first insertion portion 51 into which the drive shaft 31 is inserted, a second insertion portion 52 into which the rotation shaft 14 is inserted, a first insertion portion 51 and a first insertion portion 51. And an optical path 53 communicating with the two insertion portions 52. The first insertion portion 51 and the second insertion portion 52 are provided coaxially. The first insertion portion 51 is formed at one end portion in the axial direction of the connection member 5, and the second insertion portion 52 is formed at the other end portion in the axial direction of the connection member 5. The optical path 53 is formed coaxially with the first insertion portion 51 and the second insertion portion 52.

  FIG. 5 is a cross-sectional view taken along the line V-V in FIG. 3, and is a cross-sectional view in a direction orthogonal to the rotation center of the vehicle display device according to the embodiment. The cross-sectional shape of the second insertion portion 52 is, for example, a rectangle as shown in FIG. The rotary shaft 14 is inserted into the second insertion portion 52 so as not to be rotatable relative to the connection member 5, for example, press-fitted. The cross-sectional shape of the first insertion part 51 may be a rectangle like the cross-sectional shape of the second insertion part 52, or may be another shape such as a circle or a polygon. The drive shaft 31 is inserted into the first insertion portion 51 so as not to rotate relative to the connection member 5, for example, press-fitted.

  A stopper 54 is provided inside the connecting member 5. The stopper 54 is an annular component that protrudes from the inner surface of the connection member 5 toward the central axis. A through hole that penetrates the stopper 54 in the axial direction is formed at the center of the stopper 54. This through hole is an optical path 53 that connects the first insertion portion 51 and the second insertion portion 52. The stopper 54 defines the insertion depth when the drive shaft 31 is inserted into the first insertion portion 51.

  When the drive shaft 31 is inserted into the first insertion portion 51 and the rotation shaft 14 is inserted into the second insertion portion 52, the rotation shaft 14 is positioned on the extension line of the drive shaft 31 and coaxially. Further, the tip surface 31b of the drive shaft 31 and the tip surface 14a of the rotating shaft 14 face each other with the optical path 53 interposed therebetween. Therefore, as indicated by an arrow Y1 in FIG. 3, the light emitted from the light source 3 and incident on the drive shaft 31 from the base end surface 31a and emitted from the front end surface 31b passes through the optical path 53 to the front end surface of the rotating shaft 14. 14a. The light incident from the distal end surface 14a propagates to the pointer light emitter 15 via the rotating shaft 14, and is reflected inside the pointer light emitter 15 at the inclined portion 15d. The light reflected by the inclined portion 15d propagates in the exposed portion 15a from the proximal end side toward the distal end side as indicated by the arrow Y2, and is emitted outward from each portion of the front surface 15c as indicated by the arrow Y3. . That is, the exposed portion 15 a of the pointer light emitter 15 emits light from the light source 3 by light passing through the drive shaft 31, the optical path 53, the rotation shaft 14, and the pointer light emitter 15.

  An example of a more detailed configuration of the display unit 10 will be described with reference to FIG. The back side of the substrate 18 is covered with a back cover 25. The light source 3 and the motor 30 are connected to a control circuit formed on the substrate 18. The operations of the light source 3 and the motor 30 are controlled by the control circuit of the substrate 18. The board 18 is provided with a dial light source 19. The dial light source 19 emits light from the back side toward the dial plate 11 to emit the scale lines 11b and the numbers 11c. The dial plate 11 is fixed to the front wall portion 4b. The front wall portion 4 b is a wall portion facing the substrate 18 and is located on the front side in the depth direction with respect to the substrate 18. In the front wall portion 4b, it is preferable that at least a region corresponding to the dial plate 11 transmits the light from the dial plate light source 19. A through hole 4c is formed in the front wall portion 4b. The through hole 4 c is provided coaxially with the drive shaft 31 of the motor 30. The opening area of the through hole 4 c is larger than the opening area of the through hole 11 d of the dial 11. In the present embodiment, the dial plate 11 is fixed to the front wall portion 4b by an adhesive means such as a double-sided tape. Thereby, the diameter of the through hole 11d is reduced. For example, the diameter of the through hole 11d can be reduced as compared with a case where a claw provided on the front wall portion 4b is engaged with the through hole 11d and the dial 11 is fixed to the front wall portion 4b.

  As shown in FIG. 2, the pointer main body 13 has a shielding part 17. The shielding part 17 shields the through hole 11d of the dial 11 from the viewing position 2 side. More specifically, the shielding part 17 integrally covers the through hole 11d and the area around the through hole 11d from the front side. The shielding part 17 shields light leaking from the back side of the dial 11 to the front side through the gap between the through hole 11 d and the rotating shaft 14. Moreover, the shielding part 17 covers the through-hole 11d so that it cannot be seen from the viewing position 2. The shielding part 17 can cover at least the gap between the through-hole 11d and the rotating shaft 14, and can shield light leaking to the front side through the gap. However, the shielding part 17 may not shield all of the through holes 11d, and may have a hole part that allows light passing through the pointer light emitter 15 to pass to the front side.

  The shielding part 17 of this embodiment is a part of the pointer cover 16. The pointer cover 16 has a linear side surface portion 16d. The side surface portion 16d is provided on the tip side of the pointer cover 16 with respect to the predetermined position 16e. The side surface portions 16d are provided on both sides of the pointer cover 16 in the width direction. The pair of side surface portions 16d and 16d are closer to each other toward the distal end side of the pointer main body 13. That is, the tip end side of the pointer cover 16 with respect to the predetermined position 16e has a tapered shape in which the width between the side surface portions 16d and 16d becomes narrower toward the tip end side.

  The shielding part 17 protrudes in the width direction of the pointer main body 13 on the proximal end side with respect to the predetermined position 16e. More specifically, the edge portion 17a of the shielding portion 17 protrudes in the width direction of the pointer main body 13 from the extended line of the side surface portion 16d on the base end side with respect to the predetermined position 16e. The range in which the shielding part 17 is provided is a predetermined range including the rotation center C <b> 1 in the length direction of the pointer main body 13. The shielding portion 17 of the present embodiment is provided from the predetermined position 16e to the proximal end of the pointer main body 13. The shielding portion 17 protrudes the largest in the width direction at the position of the rotation center C1 in the length direction of the pointer main body 13, and the amount of protrusion decreases as the distance from the rotation center C1 increases in the length direction. The planar shape of the shielding part 17 is determined based on the area | region demonstrated with reference to FIG. 5, for example. In FIG. 5, a region R <b> 1 is a minimum required as a region covered by the shielding portion 17, in other words, an orthographic projection region of the shielding portion 17 with respect to the dial 11. In other words, the outer edge of the shielding part 17 needs to be located on the region R1 or outside the region R1. The region R1 is determined based on the value of the radius of the through hole 11d and the size of the gap between the dial 11 and the shielding portion 17 in the depth direction. The region R1 is determined so that, for example, when the light passing through the through hole 11d diffuses at an angle of 45 degrees from the outer edge of the through hole 11d, the diffused light can be blocked. The shape of the region R1 is a shape obtained by expanding the shape of the through hole 11d by a predetermined width.

  The vehicle display device 1 of the present embodiment can reduce the diameter of the through hole 11d as will be described below with reference to FIGS. Thereby, in the display apparatus 1 for vehicles of this embodiment, the width | variety of the shielding part 17 is made small and slimming of the pointer | guide 12 is implement | achieved. 7 is a plan view of a pointer according to the comparative example, FIG. 8 is a cross-sectional view of the pointer according to the comparative example, and FIG. 9 is a cross-sectional view of the rotation shaft of the pointer according to the comparative example. 8 is a cross-sectional view taken along the line VIII-VIII in FIG. 7, and FIG. 9 is a cross-sectional view taken along the line IX-IX in FIG.

  As shown in FIG. 8, the rotation shaft 114 of the pointer 112 according to the comparative example has an insertion portion 114 a into which the drive shaft 31 of the motor 30 is inserted. The insertion portion 114 a is a recess formed on the tip surface of the rotating shaft 114. Thus, when the drive shaft 31 is inserted with respect to the rotating shaft 114, it is difficult to reduce the diameter of the rotating shaft 114 and the through hole 11d. Specifically, as can be seen from FIG. 9, the outer peripheral surface of the rotating shaft 114 expands radially outward in order to secure a space for the insertion portion 114a into which the drive shaft 31 is inserted. Therefore, it is difficult to reduce the outer diameter of the rotating shaft 114, and as a result, it is difficult to reduce the diameter of the through hole 11d. Therefore, the region R2 that is at least required as a region to be covered by the shielding part 117 tends to be large. For this reason, the shape of the shielding part 117 is a shape that protrudes greatly in the width direction as shown in FIG. 7, for example, a circle with a small difference between the major axis and the minor axis.

  On the other hand, in the vehicle display device 1 according to the present embodiment, the drive shaft 31 of the motor 30 and the rotary shaft 14 of the pointer 12 are connected by the connecting member 5 disposed on the light source 3 side of the dial 11. . The connection member 5 has a concave second insertion portion 52 into which the rotary shaft 14 is inserted. Since the rotating shaft 14 is the convex side of the fitting, the diameter of the rotating shaft 14 and the diameter of the through hole 11d can be reduced.

  As will be described below with reference to FIGS. 10 and 11, the pointer 12 of the present embodiment is made slim. FIG. 10 is a plan view showing dimensions of the pointer according to the present embodiment. In FIG. 10, the maximum cap width Wmax is the maximum width of the shielding part 17. The predetermined pointer width W1 is the width of the pointer main body 13 at the predetermined position 16e, in other words, the width of the pointer main body 13 at the protrusion start position of the shielding portion 17. The maximum cap width Wmax of the present embodiment is 1.5 times or less the predetermined pointer width W1. In the pointer 112 (FIG. 7) of the comparative example, the cap maximum width Wmax0 is about 3.2 times the predetermined pointer width W0. Therefore, the pointer 12 according to the present embodiment is significantly slimmer than the pointer 112 according to the comparative example. In addition, the lower limit value of the cap maximum width Wmax is determined so that light leakage to the front side through the through hole 11d can be prevented. The lower limit value of the cap maximum width Wmax is, for example, the theoretical minimum value of the through hole 11d, for example, the inner diameter of the through hole 11d when the clearance between the through hole 11d and the rotating shaft 14 (shaft cover portion 16c) is zero. It is determined accordingly. As an example of the lower limit value of the cap maximum width Wmax, for example, 1.1 times the predetermined pointer width W1 or a value in the vicinity thereof may be mentioned.

  FIG. 11 is another plan view showing the dimensions of the pointer according to the present embodiment. In FIG. 11, the distance to the tip 17b of the shielding portion 17 (hereinafter simply referred to as “distance to the tip”) LW1 is the distance between the rotation center C1 of the pointer body 13 and the tip 17b of the shielding portion 17. The distance in the width direction. The tip 17b is a portion that protrudes in the width direction from the center line X1 of the pointer body 13 in the shielding portion 17 to the largest extent. The predetermined length LL1 is a distance in the length direction of the pointer main body 13 from the rotation center C1 of the pointer main body 13 to the predetermined position 16e. In the pointer 12 according to the present embodiment, the distance LW1 to the tip is ½ or less of the predetermined length LL1, more specifically, 0.37 times or less of the predetermined length LL1. In the pointer 112 of the comparative example, the distance LW0 to the tip is one or more times the predetermined length LL0. Therefore, the pointer 12 according to the present embodiment is significantly slimmer than the pointer 112 according to the comparative example.

  Note that as the ratio of the predetermined length LL1 to the length of the pointer main body 13 increases, it becomes easier to give an impression that the pointer main body 13 becomes wider as a whole. For this reason, it is considered that it is not preferable that the predetermined length LL1 is too long. The predetermined length LL1 is desirably shorter than the length LL2 from the rotation center C1 to the tip of the pointer body 13, and is preferably, for example, ½ or less of the length LL2. The predetermined length LL1 may be 1/3 or less of the length LL2 up to the tip of the pointer body 13 or 1/5 or less. The lower limit value of the distance LW1 to the tip is appropriately determined according to the predetermined length LL1 and the region R1, but may be, for example, 1/5 of the predetermined length LL1.

  As described above, the pointer 12 according to the present embodiment has a small magnification of the cap maximum width Wmax with respect to the predetermined pointer width W1 and a small magnification of the distance LW1 to the tip with respect to the predetermined length LL1. A sharp pointer body 13 is realized in which the presence is weakened and the linear needle portion is emphasized. Moreover, in the pointer 12 of this embodiment, the shape of the edge portion 17a of the shielding portion 17 is an arc shape with a constant curvature. The radius of the arc of the edge portion 17a is larger than the distance LW1 to the tip. Thereby, the presence of the shielding part 17 is weakened. The value of the radius of the arc of the edge portion 17a may be, for example, the same value as the length LL2 to the tip of the pointer main body 13 or the same value as the length LL2.

  As described above, the vehicle display device 1 according to the present embodiment includes the light source 3, the dial 11 (plate member), the drive shaft 31, the pointer 12, and the connection member 5. The dial plate 11 is disposed between the light source 3 and the viewing position 2, blocks light from the light source 3, and has a through hole 11d. The drive shaft 31 is disposed closer to the light source 3 than the dial 11 and transmits light emitted from the light source 3. The pointer 12 is inserted into the through-hole 11d and transmits a rotation shaft 14 through which light passes, and the pointer light emitter 15 is disposed closer to the viewing position 2 than the dial 11 and emits light by the light passing through the rotation shaft 14. The shielding portion 17 shields the through hole 11d from the viewing position 2 side.

  The connection member 5 is a light-shielding member disposed on the light source 3 side of the dial plate 11 and includes a first insertion portion 51 into which the drive shaft 31 is inserted and a second insertion portion into which the rotation shaft 14 is inserted. 52, and an optical path 53 that communicates the first insertion portion 51 and the second insertion portion 52, and connects the drive shaft 31 and the rotation shaft 14 so as to be integrally rotatable. In the vehicle display device 1 of the present embodiment, the diameter of the through hole 11d provided in the dial 11 can be reduced. By reducing the diameter of the through hole 11d, the area to be covered by the shielding portion 17 is reduced, and the degree of freedom in designing the pointer 12 is improved. For example, reducing the diameter of the through-hole 11d makes it possible to reduce the cap maximum width Wmax of the shielding part 17 and the distance LW1 to the tip. Therefore, reducing the diameter of the through-hole 11d makes it possible to realize at least one of slimming the pointer 12, reducing the protrusion amount of the shielding portion 17, and reducing the weight of the pointer 12.

  Further, in the vehicle display device 1 of the present embodiment, the rotating shaft 14 is covered by the light-shielding shaft cover portion 16c. As shown in FIG. 3, the shaft cover portion 16 c covers a portion of the rotating shaft 14 that is not inserted into the connecting member 5, that is, a portion on the proximal end side of the rotating shaft 14. The shaft cover portion 16c restricts light emission from the rotating shaft 14, for example, emission of light directed radially outward, and suppresses light leakage from the through hole 11d to the viewing position 2 side.

  Further, in the vehicle display device 1 of the present embodiment, it is possible to lower the center of gravity of the portion that is rotationally driven by the motor 30. When the insertion portion 114a is provided on the rotating shaft 114 as in the comparative example (see FIG. 8), the diameter of the rotating shaft 114 is increased. As a result, the mass of the pointer 112 increases, and the position of the center of gravity tends to be the front side position in the depth direction. On the other hand, in this embodiment, the pointer 12 can be reduced in weight by reducing the diameter of the rotating shaft 14. By reducing the weight of the pointer 12, the position of the center of gravity is lowered to the back side in the depth direction, and the load on the motor 30 is reduced. Further, the reduction in the diameter of the rotating shaft 14 relaxes the mass restriction of the pointer 12 for adjusting the position of the center of gravity. Therefore, the degree of freedom in the design of the pointer 12 is increased.

  The plate-like member that blocks light from the light source 3 and has the through-hole 11d is not limited to a member (hereinafter referred to as a “dial plate main body”) on which an indicator portion and a pattern are arranged. For example, the dial 11 may be provided with a decorative plate having a through hole 11d so as to surround the rotation shaft 14 of the pointer 12, and a dial main body surrounding the decorative plate may be provided outside the decorative plate. The shielding part 17 shields the through-hole 11d of the decorative plate from the front side. In such a case, the decorative plate or a combination of the decorative plate and the dial main body is a plate-like member.

  The drive shaft 31 is typically an output shaft of the motor 30, but is not limited thereto. The drive shaft 31 is a rotary shaft that is rotated by torque generated by a drive source. For example, the drive shaft 31 is provided on a different shaft from the output shaft of the motor 30 and is driven to rotate by the motor 30 via a gear mechanism or the like. There may be.

[First Modification of Embodiment]
A first modification of the embodiment will be described. The vehicle display device 1 according to the first modified example is different from the vehicle display device 1 according to the above embodiment in that, for example, the stopper 55 of the connection member 5 shields the central portion of the optical path 53. FIG. 12 is a cross-sectional view in the direction along the rotation center of the vehicle display device according to the first modification of the embodiment, and FIG. 13 is along the rotation center of the vehicle display device according to the first modification of the embodiment. FIG. 14 is a sectional view showing an example of a stopper according to a first modification of the embodiment, and FIG. 15 is a sectional view showing another example of a stopper according to the first modification.

  The pointer 12 according to the first modification is a so-called full length light emission type pointer. The pointer cover 16 is provided with a slit 16b over substantially the entire length from the distal end to the proximal end of the pointer light emitter 15. Reflecting surfaces 15 e and 15 f are provided inside the pointer light emitter 15. The reflecting surfaces 15 e and 15 f surround a hollow portion 15 g provided inside the pointer light emitter 15. The hollow portion 15g has a triangular cross-sectional shape in a direction perpendicular to both the depth direction and the length direction of the pointer 12. The hollow portion 15g is disposed on an extension line of the rotating shaft 14. Further, the reflection surfaces 15 e and 15 f are provided at positions on the extension line of the rotating shaft 14. The reflecting surface 15 e reflects light propagating from the rotating shaft 14 side toward the distal end side of the pointer main body 13. The reflecting surface 15 f reflects light propagating from the rotating shaft 14 side toward the proximal end side of the pointer main body 13.

  Part of the light traveling from the rotating shaft 14 toward the front surface passes through the hollow portion 15g without being reflected by the reflecting surfaces 15e and 15f, and exits from the portion 15h on the extended line of the rotating shaft 14 in the exposed portion 15a. Here, in the drive shaft 31, the light traveling through the rotation center C1 is stronger than the light traveling near the outer periphery. For this reason, in the exposed portion 15a, the vicinity of the rotation center C1 is likely to emit light brighter than other portions. If the vicinity of the rotation center C1 becomes too bright compared to other portions, the brightness distribution of the pointer light emitter 15 becomes non-uniform.

  The stopper 55 of the first modification has a light shielding part 55 a that shields the central part of the optical path 53. As shown in FIG. 13, the light blocking portion 55 a is provided in a partial region including the rotation center C <b> 1 in the optical path 53 and blocks light. Of the light emitted from the drive shaft 31, the light traveling in the vicinity of the rotation center C1 as shown by the arrow Y4 is blocked by the light blocking portion 55a. Of the light emitted from the drive shaft 31, the light traveling radially outside the light shielding portion 55a as indicated by the arrow Y5 is incident on the rotary shaft 14 via the optical path 53 and is reflected to the reflecting surfaces 15e and 15f. move on. Since the light traveling in the vicinity of the rotation center C1 is blocked by the light blocking portion 55a, the brightness distribution of the pointer light emitter 15 is homogenized.

  14 is a cross-sectional view taken along the line XIV-XIV in FIG. 13 and is a cross-sectional view of the connecting member in a direction orthogonal to the rotation center. The cross-sectional shape of the light shielding part 55a is circular as shown in FIG. 14, for example. The three-dimensional shape of the light shielding part 55a is a disk shape or a cylindrical shape. The light shielding portion 55a is connected to the cylindrical main body portion of the connection member 5 through the connection portion 55b. As shown in FIG. 15, the light-shielding portion 55a may be a plate-shaped component having a predetermined width. The light shielding part 55a shown in FIG. 15 has both ends connected to the inner surface of the connecting member 5, and divides the inside of the connecting member 5 into two light transmitting regions (optical paths) on the base end side and the tip end side.

  In addition, the shielding part 17 provided in the full length light emission type pointer 12 may not shield all the through holes 11d. In the shielding part 17, the part corresponding to the slit 16b can transmit light toward the front side in the depth direction.

[Second Modification of Embodiment]
A second modification of the embodiment will be described. FIG. 16 is a cross-sectional view of a main part in a direction along the rotation center of the vehicle display device according to the second modified example of the embodiment. The vehicle display device 1 according to the second modified example is different from the vehicle display device 1 according to the above-described embodiment in that the rotating shaft 14 has a protrusion 14 b that can be inserted into the stopper 54.

  As shown in FIG. 16, a protrusion 14 b is provided at the tip of the rotating shaft 14. The protrusion 14 b has a smaller diameter than the proximal end portion of the rotating shaft 14. The radius of the protrusion 14b is equal to or smaller than the size that can be inserted into a through hole (optical path 53) that penetrates the stopper 54. The rotating shaft 14 is inserted into the second insertion portion 52 of the connecting member 5 to a depth where at least a part of the tip end side of the protrusion 14b enters the through hole of the stopper 54.

  According to the vehicle display device 1 of the second modified example, the size B1 of the gap between the drive shaft 31 and the rotary shaft 14 is reduced as compared with the case where the protrusion 14b is not provided. Therefore, diffusion of light emitted from the drive shaft 31 is suppressed, and more light enters the rotation shaft 14. Therefore, the amount of light guided from the drive shaft 31 to the rotary shaft 14 increases. Further, the protrusion 14 b functions as a guide portion for aligning the rotation shaft 14 and the connection member 5, and can make sure that the rotation shaft 14 is fully press-fitted into the second insertion portion 52. .

[Third Modification of Embodiment]
A third modification of the embodiment will be described. FIG. 17 is a cross-sectional view of the main part in the direction along the rotation center of the vehicle display device according to the third modification of the embodiment, and FIG. 18 is a cross-sectional view along XVIII-XVIII in FIG. FIG. 19 is a cross-sectional view of the fitting portion between the connection member and the drive shaft, and FIG. 19 is a cross-sectional view taken along the line XIX-XIX in FIG. In the vehicle display device 1 according to the third modification, a fitting form in which importance is placed on securing a holding force is employed in the fitting portion between the connecting member 5 and the drive shaft 31, and the fitting between the connecting member 5 and the rotating shaft 14 is performed. The part adopts a fitting form that emphasizes the ease of fine adjustment of the rotational position.

  As shown in FIG. 18, the cross-sectional shape of the first insertion portion 51 of the connection member 5 and the cross-sectional shape of the drive shaft 31 are the same shape. The cross-sectional shapes of the first insertion portion 51 and the drive shaft 31 are typically regular polygonal shapes having the same number of angles, and in this embodiment, the regular octagonal corners are rounded. Since the cross-sectional shapes of the first insertion portion 51 and the drive shaft 31 are the same polygonal shape, the holding force for the connection member 5 to hold the drive shaft 31 is high. For example, the occurrence of relative rotation (idling) between the drive shaft 31 and the connection member 5 is suitably restricted.

  As shown in FIG. 19, the cross-sectional shape of the second insertion portion 52 of the connection member 5 is a circle (preferably a perfect circle). On the other hand, the cross-sectional shape of the rotating shaft 14 is a polygon, for example, a regular octagon. Since the cross-sectional shape of the second insertion portion 52 is circular, position adjustment when the rotary shaft 14 is press-fitted into the second insertion portion 52 is easy. It is possible to press-fit the rotary shaft 14 into the second insertion portion 52 at an optimal rotational position by adjusting the indicated value of the pointer 12.

  As described above, in the vehicle display device 1 according to the third modified example, a large holding force in the fitting portion between the drive shaft 31 and the first insertion portion 51 that is likely to be applied with a relatively large load among the two fitting portions. Is secured. Further, fine adjustment of the rotational position is facilitated at the fitting portion between the rotating shaft 14 and the second insertion portion 52. Therefore, both the prevention of the slipping of the pointer 12 and the ease of fine adjustment of the pointer instruction value in the press-fitting process are compatible.

[Fourth Modification of Embodiment]
A fourth modification of the embodiment will be described. FIG. 20 is a cross-sectional view in the direction along the rotation center of the vehicle display device according to the fourth modification example of the embodiment. The connection member 5 according to the fourth modification has an outer peripheral light-shielding part 56. The outer peripheral light-shielding part 56 blocks light diffusing from the drive shaft 31 and suppresses light leakage through the through hole 11d.

  As shown in FIG. 20, the outer peripheral side light-shielding portion 56 is provided at the rear side end portion of the connection member 5. The outer periphery side light-shielding part 56 covers the drive shaft 31 from the outer side in the radial direction. The outer peripheral side light-shielding part 56 is a skirt part whose diameter is increased toward the back side in the depth direction. The drive shaft 31 of the present embodiment has a stepped shape in which the distal end portion has a smaller diameter than the proximal end portion. The outer peripheral side light-shielding part 56 is provided to the back side in the depth direction from the step part 31c in which the diameter of the drive shaft 31 changes discontinuously. The outer peripheral side light shielding portion 56 blocks light radiated from the drive shaft 31 toward the radially outer side or the front surface side in the depth direction, and suppresses diffusion of light from the drive shaft 31. Therefore, the outer periphery side light-shielding part 56 can reduce the light leakage from the through-hole 11d to the front side.

[Fifth Modification of Embodiment]
A fifth modification of the embodiment will be described. FIG. 21 is a cross-sectional view in the direction along the central axis of the connection member according to the fifth modification of the embodiment, FIG. 22 is a cross-sectional view showing when the drive shaft is inserted into the connection member according to the fifth modification, and FIG. These are sectional drawings explaining the effect | action of the removal prevention with respect to the drive shaft of the connection member of a 5th modification.

  As shown in FIG. 21, the connection member 5 according to the fifth modification has a main body 57, a first soft part 58, and a second soft part 59. The main body 57 is a cylindrical member and includes a first insertion portion 51, a second insertion portion 52, and a stopper 54. An optical path 53 is provided at the center of the stopper 54. The first soft part 58 is disposed in the first insertion part 51. The second soft part 59 is disposed in the second insertion part 52. In the main body 57, the inner surface corresponding to the first insertion portion 51 has a groove 57a. The depth of the groove 57a becomes deeper from the front side in the depth direction, that is, from the entrance side to the back side of the first insertion portion 51. The first soft part 58 fills the groove 57 a and constitutes a fitting surface of the first insertion part 51 together with the main body 57.

  In the main body 57, the inner surface corresponding to the second insertion portion 52 has a groove 57b. The depth of the groove 57b becomes deeper from the back side in the depth direction, that is, from the entrance side to the back side of the second insertion portion 52. The second soft part 59 fills the groove 57 b and constitutes a fitting surface of the second insertion part 52 together with the main body 57.

  The first soft part 58 and the second soft part 59 are softer than the main body 57 and easily elastically deform. The main body 57 is made of a resin such as polycarbonate (PC) or polyacetal (POM). Each of the soft portions 58 and 59 is made of a member softer than the main body 57, for example, rubber. Each soft part 58, 59 and the main body 57 are integrally molded by two-color molding or the like.

  As shown in FIG. 22, when the drive shaft 31 is press-fitted into the first insertion portion 51 of the connecting member 5, the first soft portion 58 is located behind the first insertion portion 51 together with the drive shaft 31 as indicated by an arrow Y <b> 6. Try to go to the side. Here, since the groove 57a becomes deeper toward the back side, the first soft part 58 can escape toward the bottom part of the groove 57a. That is, the compressive force acting toward the back side with respect to the first soft portion 58 is released toward the outside in the radial direction as indicated by the arrow Y7. Therefore, the reaction force and pressing force against the press-fitted drive shaft 31 are alleviated, and the load on the drive shaft 31 during press-fitting is reduced.

  As shown in FIG. 23, when a force in the direction of pulling out from the first insertion portion 51 is applied to the drive shaft 31, the drive shaft 31 tends to move relative to the connecting member 5. In this case, the first soft portion 58 tends to advance toward the inlet side of the first insertion portion 51 together with the drive shaft 31 as indicated by an arrow Y8. Here, since the groove 57a becomes shallower toward the inlet side, the first soft portion 58 is concentrated on the inlet side of the groove 57a. When the first soft portion 58 is concentrated, a large compressive force acts on the inlet side of the first soft portion 58, and the drive shaft 31 is pressed by this compressive force as indicated by an arrow Y9. Therefore, the reaction force (load) against the force for pulling out the drive shaft 31 acts to restrict the drive shaft 31 from coming out.

  Further, the second soft portion 59 can reduce the load on the rotary shaft 14 press-fitted into the second insertion portion 52 and is large with respect to the rotary shaft 14 that is about to be pulled out from the second insertion portion 52. Apply a load. According to this modification, the holding force of the shafts 14 and 31 can be improved without increasing the press-fitting allowance of the fitting portion (the wrap amount between the connecting member 5 and the shafts 14 and 31).

[Sixth Modification of Embodiment]
A sixth modification of the embodiment will be described. FIG. 24 is a cross-sectional view in the direction along the rotation center of the vehicle display device according to the sixth modification of the embodiment. The connection member 5 according to the sixth modification has a flange portion 60.

  The flange portion 60 protrudes outward in the radial direction from the outer peripheral surface of the connection member 5. The planar shape of the flange portion 60 is, for example, a circle. The flange part 60 is arrange | positioned at the front side edge part of the depth direction in the connection member 5, for example. The flange portion 60 functions as a holding portion when the drive shaft 31 and the rotary shaft 14 are press-fitted into the connection member 5. The flange portion 60 is held by an operator, a jig, or the like in a press-fitting process for press-fitting the drive shaft 31 and the rotary shaft 14. The flange portion 60 functions as a light shielding portion that shields the through hole 11d of the dial plate 11 from the back side in the depth direction. The flange portion 60 can suppress light leakage to the front side through the through hole 11d.

  Unlike the pointer cover 16 (see FIG. 3) of the above embodiment, the pointer cover 16 of the sixth modified example does not have the shaft cover portion 16c. By omitting the shaft cover portion 16c, the diameter of the through hole 11d is further reduced. When the shaft cover portion 16 c is omitted, a light shielding process may be performed on the outer peripheral surface of the rotating shaft 14. For example, a light-shielding film may be formed on the rotating shaft 14 by means such as vapor deposition.

[Seventh Modification of Embodiment]
A seventh modification of the embodiment will be described. 25 is a cross-sectional view in a direction along the rotation center of the vehicle display device according to the seventh modification of the embodiment, FIG. 26 is a perspective view of a connection member according to the seventh modification of the embodiment, and FIG. FIG. 10 is a cross-sectional perspective view of a connection member mold according to a seventh modification of the embodiment.

  As illustrated in FIG. 26, the connection member 5 according to the seventh modification has a spiral groove 61. The groove 61 is provided on the outer peripheral surface of the connection member 5. The groove portion 61 is provided from the upper end to the lower end of the connection member 5. In the connection member 5 of the seventh modification, the strength is improved by providing the groove 61.

  As will be described below with reference to FIGS. 28 and 29, weak portions are likely to occur in the connecting member 50 formed in a cylindrical shape. FIG. 28 is a perspective view showing a cylindrical connection member, and FIG. 29 is a cross-sectional perspective view of a mold for forming the cylindrical connection member. A groove is not provided on the outer peripheral surface of the connecting member 50 shown in FIG. As shown in FIG. 29, a cylindrical pin 71 corresponding to the hollow portion of the connection member 50 is provided at the center of the mold 70. The resin injected from the gate 72 flows into the cavity 73 around the pin 71. The resin that has flowed into the cavity 73 flows in two so as to bypass the pin 71, and merges on the side opposite to the gate 72. As shown in FIG. 28, a straight alignment mark called a weld (weld line) 74 having a weak fastening strength is likely to occur at the joining portion where the resin joins. From the viewpoint of improving the pull-out strength of the rotating shaft 14, it is desirable to increase the press-fitting allowance between the rotating shaft 14 and the inner diameter of the connecting member 50. On the other hand, when the press-fitting allowance is increased, there is a contradiction that cracks are likely to occur in the linear weld 74.

  In the connection member 5 according to the present modification, a weld is difficult to be formed by forming the spiral groove 61 on the outer peripheral surface. As shown in FIG. 27, the mold 80 forming the connection member 5 of the present modification has a spiral protrusion 82. A cylindrical pin 81 corresponding to the hollow portion of the connection member 5 is provided at the center of the mold 80. The protrusion 82 is provided on the inner peripheral surface 83 that faces the pin 81. The protrusion 82 is provided from the upper end to the lower end of the inner peripheral surface 83. At least a part of the resin that has flowed into the cavity 85 from the gate 84 flows along the protrusion 82 so as to draw a spiral. This makes it difficult to form a linear weld on the connecting member 5. When the connecting member 5 is formed, there is an advantage that a resin mating surface hardly occurs, and even if the mating surface is formed, the mating surface is difficult to be linear or continuous. Therefore, in the connection member 5 of this modification, it is possible to increase the press-fitting allowance between the rotating shaft 14 and the connection member 5 and improve the pull-out strength.

  The contents disclosed in the above embodiments and modifications can be executed in appropriate combination.
