Description

[Detailed description of the invention] [Industrial application field] The invention is a black face instrument for a vehicle, which is a black face when an ignition switch is turned off, and a display by transmitted illumination is performed when the ignition switch is turned on. It concerns the device.

2. Description of the Related Art As a known example of a conventional black face instrument for a vehicle of this type, there is one having a structure as shown in FIG. That is, reference numeral 1 denotes an instrument. In the instrument 1, an instrument mechanical body 2, a pointer 5 attached to a pointer shaft 3 of the instrument mechanical body 2, a pointer 5 illuminated and displayed by a fluorescent lamp 4, and transmitted illumination A dial 8 of a type and a fluorescent lamp 7 for illuminating the dial 6 with transmitted light;
Further, in front of the indicator 8, a translucent front cover 9 which looks black in reflected light and has a transmittance of, for example, 30 to 70% is mounted. 10 is the fluorescent lamp 4
And 7 for turning on and off. And in this black face instrument, the fluorescent light 4,7
When is not lit, that is, when the ignition switch is off, there is no transmitted light, so the surface of the translucent front cover 9 looks black (smoke-like) due to external reflected light, and nothing is visible. However, when the ignition switch is turned on and the fluorescent lamps 4 and 7 are lit, the hands 5
When the dial 6 is further illuminated and the dial 6 is transmitted and illuminated, the illumination is transmitted through the front cover 9 and the display state of the indicator 8 can be visually checked.

[Problem to be Solved by the Invention] However, in the black face instrument having such a structure, in order to prevent the front cover 9 from reflecting external light to the indicator 8, a dark smoke tone, that is, light transmission is required. Although the use of a front cover with a reduced degree is used, since the front cover 9 is semi-transparent, for example, when the outer surface of the front cover 9 is directly irradiated with high-brightness direct sunlight from obliquely above. Since the direct light passes through the front cover 9 and the reflected light of the indicator is strong, the function as a black face instrument is impaired. Therefore, in order to enhance this function, the display brightness of the indicator 8 must be increased using, for example, a high-brightness and expensive fluorescent lamp.
This causes a problem that the cost of the indicator 8 is significantly increased.

[Means for Solving the Problems] The present invention has been made in view of such a conventional problem, and a display surface of a self-luminous analog instrument is mounted downward in an eave part of an instrument. On the surface of the analog instrument, a louver for blocking light in the vertical direction and obliquely below the driver side is attached, and in front of the driver's seat of the instrument, a dome-shaped space whose inner surface is non-reflective is further formed. At the front of the space, a hologram reflector for reflecting the display from the analog instrument to the driver is arranged so that there is no reflection to the instrument by external light.Moreover, the display light from the instrument uses the hologram reflector. It is an object of the present invention to provide a display device capable of providing an effective display to a driver through the display device.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in FIG.

Reference numeral 11 denotes an eave portion of a vehicle instrument, which is a part of the instrument. Inside the eave portion 11, an indicator 12 is attached in a downward direction. The structure of this indicator 12 is
13, a pointer 15 attached to the pointer shaft 14 expended from the instrument machine body 13, a transmissive dial 16, a light bulb 17 for causing the dial 16 and the pointer 15 to emit light, and a light guide to the pointer 15. Of light guides 18. 19 is an indicator
It is a film-shaped louver installed on the 12 front. Reference numeral 20 denotes a dome-shaped space formed inside the instrument. The inner peripheral surface of the space 20 is provided with a non-reflective black paint 21. At the front of the dome-shaped space 20, there is arranged a hologram reflector 23 for reflecting the display of the indicator 12 incorporated in the eaves portion 11 to the driver's eye points and 22. Reference numeral 24 denotes a transparent protective cover attached to the front of the hologram reflector 23. As shown in the figure, the louver 19 transmits the display by the indicator 12 to the hologram reflecting plate 23,
Light rising from directly below or obliquely forward is formed so as to be able to block light.

The above is the configuration of the present embodiment.Next, the operation will be described. First, when the light emitting type display 12 is not illuminated and displayed, the light is only external light, but the external light 25 is The light is reflected by the hologram reflector 23 to the louver 19, but most of the reflected light is blocked by the louver 19 and does not reach the display. Some of the reflected light passes through the louver 19 and is reflected by the display 12, but the reflected light is absorbed inside the louver 19 and is not guided to the outside, so that the display
The effect of 12 is not reflected on the hologram reflection plate 23, so that the hologram reflection plate 23 becomes a black display and becomes a black face.

When the display 12 is turned on, the display light passes through the louver 19, is reflected by the hologram reflector 23, and reaches the driver's eye point 22. The virtual image is displayed by the plate 23. Therefore, according to this embodiment, the reflection of external light is effectively blocked and the display by the display 12 is effectively reflected and displayed toward the driver, so that it is effective as a black face instrument for vehicles.

[Effects of the Invention] As described above, in the present invention, the display surface of the self-luminous analog meter is mounted downward in the eaves section of the instrument, and the surface of the analog meter is inclined vertically and obliquely from the driver side. A louver that shields the lower light is attached, and a dome-shaped space whose inner surface is non-reflective is formed in front of the driver's seat of the instrument. In addition, a display from the analog instrument is displayed to the driver in front of this space. Since this is a display device having a hologram reflector for reflection, the reflection of external light is effectively blocked and the display by the display 12 is effectively reflected and displayed in the direction of the driver. Therefore, it is effective as a black face instrument for vehicles.
