Description

The present disclosure relates to improved vehicle instrument dials and vehicle instruments.

Generally, an instrument for measuring the vehicle speed or the like is arranged in front of the occupant of the vehicle. As one of such instruments, an analog type instrument is known. An analog instrument consists of a dial on which vehicle information such as numbers is displayed and a pointer that rotates on the dial, and the pointer rotates to provide information to the occupants. As a conventional technique relating to the dial of such a vehicle instrument, there is a technique disclosed in Patent Document 1.

The invention disclosed in Patent Document 1 will be described with reference to FIG. FIG. 10 corresponds to FIG. 3 of Patent Document 1. The reference numerals were reassigned as appropriate. The vehicle instrument dial 100 is a light-shielding layer 120 having an opening 130 corresponding to the shape of a number, a translucent coat layer 140 superposed on the light-shielding layer 120, and an opening on the front surface of the coat layer 140. It is provided with a character portion 920 provided at a portion overlapping the 130. A light source is arranged below the opening 130.

The entire front surface of the coat layer 140 is formed in a sawtooth cross section. This sawtooth cross section exhibits a striped pattern when viewed from the occupant. The rear surface of the character portion 920 is formed in a sawtooth cross section to match the front surface of the coat layer 140, and the front surface is formed in a flat surface shape.

By turning on the ignition switch of the vehicle, the light source arranged below the opening 130 is turned on. The light emitted from below the light-shielding layer 120 passes through the opening 130, the coat layer 140, and the character portion 920 to form an image of characters. According to the vehicle instrument dial 100, the peripheral edge of the character portion 920 is formed in a striped pattern, and the front surface of the character portion 920 through which light passes is formed flat. By these things, the character part 920 can be made to shine clearly.

Japanese Unexamined Patent Publication No. 2006-113045

However, even when the ignition switch of the vehicle is off, even if it is not necessary to visually recognize the character portion 920 due to the difference between the flat surface shape on the front surface of the character portion 920 and the sawtooth cross section on the peripheral edge thereof. Since it is clearly visible, there is a problem that the design and the commercial value are impaired.

Therefore, the present disclosure has been made in view of the above problems, and an object of the present disclosure is to provide a vehicle instrument dial and a vehicle instrument with further enhanced design while ensuring the visibility of the display. ..

In the present disclosure, a transparent base material 11, ground color layers 12, 15, 16 having display portions 91, 92, 95 provided on the base material 11, and a front surface of the base material 11 and the ground color layer 12 , 15, 16 have a first uneven pattern portion A1, A4, A7 provided on the viewer side, and a fine uneven pattern having a narrower interval than the first uneven pattern portion A1, A4, A7, and the front surface thereof. Further, in the vehicle instrument dial including the second uneven pattern portions A2, A5, A8 provided on the viewer side, the first uneven pattern portions A1, A4, A7 and the second uneven pattern portion A2, A5, and A8 are arranged so as to be adjacent to each other, and the ground color layers 12, 15, and 16 have the display portions 91, 92, and 95 located at positions corresponding to the first uneven pattern portions A1, A4, and A7. It is characterized in that it is provided.

According to the vehicle instrument dial and the vehicle instrument according to the present disclosure, the fine uneven pattern of the display portion is formed at a wider interval than the fine uneven pattern of other parts.

The embodiments of the present disclosure will be described below with reference to the accompanying drawings. In the explanation, the left and right refer to the left and right (L, R in the figure) with reference to FIG. 1, and the front and back refer to the top and bottom (Fr., Re. In the figure) with reference to FIG. The back side is called "rear".

The first embodiment of the present disclosure is shown. The vehicle instrument 200 shown in FIG. 1 is a device that is arranged in front of the occupant and displays information such as vehicle speed to the occupant.

In the vehicle instrument 200, an electronic display unit M1 for electronically displaying information such as a gasoline residual fuel gauge by a liquid crystal display element or the like is arranged in the center, and the engine speed is displayed on the left side of the electronic display unit M1. A tachometer M2 is arranged, and a speedometer M3 for displaying the vehicle speed is arranged on the right side of the electronic display unit M1.

The tachometer M2 has a dial 1 on which indicators (designs) such as a scale unit (display unit) 91 and a number unit (display unit) 92 indicating the number of rotations are formed, and a scale unit 91 and numbers on the front surface of the dial 1. It is composed of a pointer 2 that rotates along the portion 92.

The same applies to the speedometer M3. That is, the speedometer M3 rotates the dial 1 on which indicators (designs) such as the scale portion 91 and the number portion 92 indicating the vehicle speed are formed, and the front surface of the dial 1 along the scale portion 91 and the number portion 92. It consists of a moving guideline 3.

The vehicle instrument 200 has a well-known configuration for parts other than the dial 1. Although not shown, for example, the dial 1, the pointers 2, 3, the liquid crystal display element and the like are LEDs (chip type light emitting diode: Light Lighting Diode) mounted on the dial 1 side of the circuit board 8 arranged at the rear. It is illuminated by the light sources 61, 62 and the like. Further, the pointers 2 and 3 are connected to a shaft portion 71 protruding toward the dial 1 from the drive unit 7 which is a drive source arranged on the rear surface of the circuit board 8, and is centered on the rotation center X of the shaft portion 71. Rotate to.

On the surface of the dial 1, a rectangular scale portion 91 arranged in a circumferential shape around the pointers 2 and 3 and a number portion such as 0 (zero) arranged inside the scale portion 91 corresponding to the scale portion 91. A 92, a plurality of warning lights 93 such as a turn signal, a window portion 94 for seeing through the electronic display unit M1, and the like are formed.

See FIG. The dial 1 is formed in a region that omits a translucent base material 11 and positions corresponding to the scale portion 91, the number portion 92, the warning light 93, and the window portion 94 on the rear surface of the base material 11, and is formed from the rear. A light-shielding layer (ground color layer) 12 that blocks the irradiated light, a semi-transmissive layer 13 formed at positions corresponding to the scale portion 91, the number portion 92, and the warning light 93 on the rear surface of the base material 11, and the base material. It is composed of a translucent coat layer 14 formed on the front surface of the eleven.

The light-shielding layer 12 and the semi-transmissive layer 13 may be formed on the same surface as the surface on which the coat layer 14 of the base material 11 is formed, but when they are formed on different surfaces as in the present disclosure. , It was found that a particularly high design property is obtained.

As the material of the base material 11, for example, transparent or translucent glass, polycarbonate resin, or the like is adopted. The light-shielding layer 12 can be composed of a black coating film. The translucent layer 13 can be composed of a translucent (smoke color) coating film, contains a diffusing agent in the paint, and is a layer for uniformly diffusing the light emitted from the rear of the base material 11. .. The translucent layer 13 can be composed of a white or milky white coating film. The coat layer 14 can be composed of a colorless and transparent coating film.

The light-shielding layer 12 is appropriately formed with non-printing portions at positions corresponding to the scale portion 91, the number portion 92, the warning light 93, and the window portion 94. The non-printing portion is formed so as to draw a character of 0, for example. The non-printed portion allows the passage of light emitted from behind. The semi-transmissive layer 13 is formed so that the boundary with the light-shielding layer 12 overlaps the light-shielding layer 12 (on the rear surface side).

The shape of the number part 92 is an alphabet, / (slash) if it is a character related to vehicle information. Any character such as (dot) can be selected. Further, as the warning light 93, various warning lights such as a high beam light and a residual fuel warning light can be arranged in addition to the turn signal.

In the coat layer 14, the regions other than the tachometer M2 and the speedometer M3 are formed in a flat surface shape, and the regions of the tachometer M2 and the speedometer M3 are in a striped pattern (so-called spindle shape or record board pattern) composed of fine irregularities. It is formed. Therefore, the coat layer 14 is formed in a flat surface shape at and around the position corresponding to the warning light 93 and the window portion 94, and is formed in a striped pattern at the position corresponding to the scale portion 91 and the number portion 92.

The tachometer M2 and the speedometer M3 of the dial 1 have the same configuration. Therefore, the present disclosure will be described below using the speedometer M3 as an example.

The striped pattern is a fine uneven striped pattern composed of fine irregularities in which a plurality of circles drawing concentric circles centered on the rotation center X of the pointer 3 are arranged in succession. Each striped line is formed in a U-shape with the same width. Further, the striped pattern is formed on the third striped pattern portion (third uneven pattern portion) A3 and the third striped pattern portion A3 in which the line spacing (pitch) is continuous at the pitch P3 in order from the rotation center X side of the pointer 3. Adjacent to the first striped pattern portion (first uneven pattern portion) A1 which is adjacent and continuous at a pitch P1 whose line spacing is wider (larger) than the pitch P3, and adjacent to the first striped pattern portion A1 and whose line spacing is pitch P3. It has a second striped pattern portion (second uneven pattern portion) A2 that is continuous at the same pitch P2. Here, the pitches P2 and P3 are 0.13 mm, and the pitch P1 is 0.18 mm.

The scale portion 91 is formed in the second striped pattern portion A2, and the number portion 92 is formed in the first striped pattern portion A1.

When the light source 61 below the base material 11 is turned on by being formed in this way, the light emitted from the light source 61 passes through the base material 11 at the scale portion 91 and the number portion 92, and then the coat layer 14 It is visually recognized by being interfered with by (so-called transmitted illumination). Since the pitch P2 is narrowly spaced at the scale portion 91, the contour of the scale portion 91 appears to be slightly swaying and shining to the viewer, but at the number portion 92, the pitch P1 is widely spaced. Therefore, the outline of the number part 92 fluctuates and cannot be seen by the viewer, but rather clearly shines. In this way, the visibility of the number unit 92 can be ensured.

Further, when the striped pattern of the dial 1 is irradiated with external light, the light is reflected by the viewer in the streaky Asahi light pattern as shown by the region K in FIG. In the second striped pattern portion A2, since the pitch P2 is narrowly spaced, the number of reflecting portions increases, and as a result, the scale portion 91 located in the region K becomes difficult to see. However, in the third striped pattern portion A3, since the pitch P3 has a wider interval than the pitch P2, the number of reflecting portions is reduced, and as a result, the number portion 92 located in the region K is not obscured. In this way, the visibility of the number unit 92 can be ensured.

Further, the first striped pattern portion A1 having a wide pitch interval (pitch P1) is placed between the second striped pattern portion A2 and the third striped pattern portion A3 having a narrower pitch interval (pitch P2, P3) than the first striped pattern portion A1. By arranging the pattern in, it becomes difficult for the viewer to notice the change in the pitch interval due to the illusion of the eyes, so that it is possible to provide a dial or a vehicle instrument for a vehicle instrument having a high appearance and commercial value.

Further, as a method for taking measures against the deterioration of the visibility of the number portion 92 due to the reflection of the external light of the striped pattern, the striped pattern is also formed on the number portion 92 in the embodiment of the present disclosure as compared with the case where only the number portion 92 is not provided with the striped pattern. Since it is formed, the reflection of the streaky light when it is irradiated with external light is not cut off, so that it is possible to suppress the deterioration of the appearance of the texture. That is, it is possible to provide a dial or a vehicle instrument for a vehicle instrument having a high appearance and commercial value while ensuring visibility.

In the present embodiment, the pitch P1 is 0.18 mm, but if it is 0.15 mm or more, the visibility of the number part 92 is not impaired, and if it is 0.2 mm or less, the striped pattern feels strange. I found it difficult to feel. Therefore, the pitch P1 is preferably in the range of 0.15 mm to 0.2 mm.

A second embodiment of the present disclosure is shown in FIGS. 4 and 5. The same parts and equal parts as those in the first embodiment described above will be described with the same reference numerals.

In the present embodiment, the first step is to gradually widen the pitch interval from the pitch P2, which moderates the difference in the fine uneven pattern near the boundary between both the first striped pattern portion A1 and the second striped pattern portion A2. It has a gradual change striped pattern portion (gradual change uneven pattern portion) G1. That is, the pitches P21, P22, and P23 of the first gradual fringe pattern portion G1 have a relationship of P2 <P21 <P22 <P23 <P1. In addition, the second gradual variation fringe in which the pitch interval gradually narrows from the pitch P1 that moderates the difference in the fine uneven pattern near the boundary between both the first striped pattern portion A1 and the third striped pattern portion A3. It has a pattern portion (gradual change uneven pattern portion) G2. That is, the pitches P31, P32, and P33 of the second gradual fringe pattern portion G2 have a relationship of P1> P33> P32> P31> P3. The first gradually changing striped pattern portion G1 may be formed in either the region of the first striped pattern portion A1 or the second striped pattern portion A2. Further, the second gradually changing striped pattern portion G2 may be formed in any region of the first striped pattern portion A1 and the third striped pattern portion A3.

By being formed in this way, the change in the pitch interval is made gentle, so that the viewer is less likely to notice the change in the pitch interval. Therefore, a dial or a vehicle instrument for a vehicle instrument having a high appearance and commercial value is provided. be able to.

A third embodiment of the present disclosure is shown in FIG. The same parts and equal parts as those in the first embodiment described above will be described with the same reference numerals.

In the present embodiment, the first colored layer (ground color layer) 15 is provided between the base material 11 and the light-shielding layer 12 at the position corresponding to the second striped pattern portion A2, and corresponds to the third striped pattern portion A3. A second colored layer (ground color layer) 16 is provided between the base material 11 and the light-shielding layer 12 at the position where the background color is formed. The first colored layer 15 can be composed of a silver-colored coating film. The second colored layer 16 can be formed of a gunmetal-colored coating film.

By being formed in this way, the background of the second striped pattern portion A2 is the first colored layer 15, the background of the first striped pattern portion A1 is the light-shielding layer 12, and the background of the third striped pattern portion A3 is the second colored layer. By changing the background color of the striped background in this way, it becomes difficult for the viewer to notice the change in the pitch interval. can.

A fourth embodiment of the present disclosure is shown in FIG. The same parts and equal parts as those in the first embodiment described above will be described with the same reference numerals.

In the first embodiment, the coat layer 14 is formed in a striped pattern at the positions corresponding to the scale portion 91 and the number portion 92, but the coat layer 14 of the present embodiment is formed only at the position corresponding to the number portion 92. It is formed in a striped pattern. The fourth striped pattern portion A4 of the striped pattern at the position corresponding to the number portion 92 is a pattern in which a plurality of circles drawing concentric circles centered on the rotation center X of the pointer 3 are continuously arranged. Further, each line of the fourth striped pattern portion A4 is formed in a U-shape in cross section having the same width. Further, in the fourth striped pattern portion A4, the line spacing is continuous at the pitch P4 from the rotation center X side of the pointer 3, and the pitch P4 is 0.18 mm.

On the outside of the fourth striped pattern portion A4 of the dial 1 (opposite to the pointer 3), the first decorative member (part) 4 is arranged in front of the dial 1 and inside the fourth striped pattern portion A4 (on the side opposite to the pointer 3). On the side of the pointer 3), a second decorative member (part) 5 is arranged in front of the dial 1. The first decorative member 4 is made of, for example, a transparent acrylic resin, and has a quadrangular cross section having a slope portion 41 such that the top surface (front surface) is low on the inside and high on the outside, and is viewed from the viewer side. It is formed in a ring shape that surrounds the fourth striped pattern portion A4. The second decorative member 5 is made of, for example, black ABS resin or the like, has a quadrangular cross section, and is formed in a disk shape inside the fourth striped pattern portion A4 when viewed from the viewer side.

Further, the first decorative member 4 has a fifth striped pattern portion (second uneven pattern portion) continuous on the slope portion 41 at a pitch P5 narrower than the pitch P4 of the fourth striped pattern portion (first uneven pattern portion) A4. ) Has A5. Further, the second decorative member 5 has a sixth striped pattern portion (third uneven pattern portion) A6 on the top surface which is continuous with a pitch P6 having the same pitch as the fifth striped pattern portion A5. The fifth striped pattern portion A5 and the sixth striped pattern portion A6 are formed so as to be adjacent to the fourth striped pattern portion A4. Here, the pitches P5 and P6 are 0.13 mm.

By being formed in this way, even when the striped pattern portions A4 and A5 are provided between the plurality of parts 4 and 5, the fourth striped pattern portion A4 having a wide pitch interval (pitch P4) is formed into the fourth striped pattern portion A4. By arranging it between the 5th striped pattern portion A5 and the 6th striped pattern portion A6 having a narrower pitch interval than the pattern portion A4 (pitch P5, P6), it becomes difficult for the viewer to notice the change in the pitch interval due to the illusion of the eyes. Therefore, it is possible to provide a dial or a vehicle instrument for a vehicle instrument having a high appearance and commercial value while ensuring visibility.
