Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to automobile instruments, and more specifically, to the contact between a light-transmissive protective cover that covers an instrument display and a facing plate arranged on the back side of the cover. It's about structure.

[Problems to be solved by the prior art and the invention]

This type of structure in a conventional automobile meter will be explained based on FIGS. 2 and 3.

FIG. 2 is a perspective view showing a general automobile instrument unit, and an instrument drive section 2 is included in the instrument case 1.
A pointer 3 is attached to the drive section 2, and a display board 4 with scales, characters, etc. is arranged behind the pointer 3, and the pointer 3 and the display board 4 constitute an instrument display section 5.

FIG. 3 is a sectional view of the instrument unit. A protective cover 6 made of a light-transmitting material such as glass or acrylic resin is provided on the front surface of the display section 5, and the back surface of the protective cover 6 has a glossy surface. Erase painting 7
A facing board 8 is arranged. This facing plate 8 covers the peripheral part of the instrument display section 5 and is intended to improve the visibility of the display section 5.
By engaging the claw 6a of the protective cover 6 with the stepped portion 1a, the protective cover 6 is held between the back surface of the protective cover 6 and the opening surface of the case 1.

With this structure, the viewer can visually recognize the instrument display section 5 through the window of the facing plate 8 through the protective cover 6. Note that a decorative panel 9 is usually arranged in front of the protective cover 6.

By the way, in the above-mentioned conventional example, a matte coating 7 is applied to the surface of the facing board 8, and the fine uneven surface of the matte coating 7 causes light to be diffusely reflected, thereby preventing direct reflection to the viewer. This improves the visibility of the part 5, but since the facing plate 8 is held under pressure between the protective cover 6 and the case 1 when the protective cover 6 is engaged with the case 1, the unevenness of the matte coating is The surface is crushed by the pressing force of the back surface of the protective cover 6, which has a mirror surface, and becomes partially planar, resulting in a glossy state called interference fringes. Therefore, for the viewer, the visibility of the instrument display is reduced, and the presence of the matte surface and the glossy surface makes the area around the display portion unattractive.

Therefore, in view of the above-mentioned conventional problems, the present invention aims to improve the visibility of the display by uniformly matting the entire periphery of the display part, and to provide an automobile instrument with good appearance. .

[Means for solving problems]

In order to achieve the above object, the automobile instrument developed according to the present invention covers the front surface of the instrument display section placed in the opening of the instrument case with a protective cover made of a light-transmitting material, and the back surface of the protective cover. An automobile instrument comprising a facing plate that covers the peripheral area of the instrument display, the facing plate being sandwiched between the back side of a protective cover and the opening surface of the instrument case, and a matte coating applied to the surface of the facing plate. The present invention is characterized in that dot-shaped projections are formed on at least one of the back surface of the protective cover and the front surface of the facing plate, and the protective cover and facing plate are pressed into contact via the projections.

[Effect]

In the above configuration, dot-shaped protrusions are formed on at least one of the back surface of the protective cover and the front surface of the facing plate, and the protective cover and facing plate are brought into pressure contact via the projections, so that the protective cover and facing plate are in pressure contact with each other. A gap corresponding to the height of the protrusions is provided between them, and since the protective cover and facing plate do not come into contact with each other in areas other than the protrusions, a gap corresponding to the height of the protrusions is provided, and the facing plate The matte coating on the surface will not be crushed by pressure welding, resulting in a uniform matte surface.

〔Example〕

FIG. 1 is a sectional view of an embodiment of the present invention. In the figure, the structure of the instrument unit is the same as that of the conventional device, so a description thereof will be omitted.

In the figure, a plurality of dot-shaped protrusions 8a are integrally formed on the surface of the facing plate 8 along its circumferential direction, and the tips of the protrusions 8a are in pressure contact with the back surface of the protective cover 6. back side and facing plate 8
Some gap is provided between it and the seven matte painted surfaces above.

Therefore, even when the claw 6a of the protective cover 6 engages with the stepped portion 1a of the case 1, the unevenness caused by the matte coating 7 on the facing plate 8 is not crushed and is evenly distributed due to this gap. Therefore, the peripheral part of the instrument display section 5 becomes a uniform matte surface.

Note that the diameter of the protrusion 8a is approximately 1 mm, and the height is approximately
Approximately 0.1 mm is appropriate, and the position is preferably located at a position that cannot be seen by the viewer, that is, inside the decorative panel 9. However, if the diameter of the protrusions 8a is small and the number of protrusions is small and unnoticeable,
It does not matter if it is placed inside the window of the decorative panel 9.

Further, in the above embodiment, the projections are provided on the front surface of the facing plate 8, but it goes without saying that they may be provided on the back surface of the protective cover 6.

〔effect〕

The present invention is as described above, and since the matte coating effect provided on the facing plate is uniformly produced around the entire display area, the visibility of the display area can be improved and its appearance can be improved.

In particular, since the protrusions are dot-shaped, even if the protrusions are provided in a position where they can be seen through the protective cover, they will not be noticeable, and the effective area that can be used for displaying the gauges will be larger, which will affect the case and, by extension, the gauges. It also becomes possible to reduce the size of the device.
