Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle warning display device,
More specifically, the present invention relates to a vehicle warning display device which is used for a meter of a vehicle and includes a warning display portion and a picture mark display portion.

[0002]

2. Description of the Related Art Generally, a vehicle warning display device displays a pictorial mark (for example, a character or mark of a brake is displayed) and a warning display (for example, a red color indicating that the side brake is not released). ) And is configured to be displayed in a paired relationship.

For example, a vehicle warning display device disclosed in Japanese Utility Model Laid-Open No. 57-130876 is composed of a picture mark display section and a warning display section, and strong fluorescent light from the outside causes the surface of the fluorescent display tube of the warning display section. In order to prevent the visibility of the warning display from being reduced by being reflected by, a polarizing filter is provided on the surface side of the fluorescent display tube, while the night illumination light of the picture mark display section enters the fluorescent display tube. Therefore, in order to prevent the night visibility of the warning display from being deteriorated, a tubular light shielding cover is provided around the fluorescent display tube.

[0004]

However, in the conventional vehicle warning display device as described above, since the polarizing filter and the like are provided, the fluorescent display tube is located far from the position of the picture mark. However, there is a problem that the visibility is not good.

Further, there is a problem that the cost is increased because the polarizing filter and the like are provided.

It is an object of the present invention to solve these problems and provide a vehicle warning display device which is excellent in visibility and low in cost.

[0007]

In order to solve such a problem, a vehicle warning display device according to the present invention comprises a warning display portion and a pictorial mark display portion, and the warning display portion comprises:
The transparent sheet lens and a warning light emitting layer formed on a part of the transparent sheet lens are provided, and the picture mark display portion is provided with a transparent lens disposed on the upper surface of the transparent sheet lens and the transparent sheet lens. And a through hole is formed in a portion of the transparent lens facing the warning light emitting layer.

[0008]

Since the warning light emitting layer is formed on the thin transparent sheet lens disposed on the back surface of the transparent lens on which the picture mark is formed, the warning light emitting layer is slightly below the picture mark (on the back surface side). ) Will be located. Therefore, the position of the warning light emitting layer becomes closer to the driver as compared with the conventional example, and the visibility of the warning display is improved. In addition, the present invention does not have a polarization filter or the like as in the conventional example, so that the cost can be reduced.

A through hole is formed in a portion of the transparent lens facing the warning light emitting layer. Therefore, external light is not reflected on the surface of the transparent lens, and it is possible to prevent the visibility of the warning display from being impaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 4, a vehicle warning display device 1
00 includes a warning display unit 1, a pictorial mark display unit 2, a warning display light source 3, a pictorial mark display light source 4, a light shielding case 5, and a light shielding cover 6.

Warning Display Unit 1 As shown in FIGS. 1, 3 and 4, the warning display unit 1 includes a transparent sheet lens 7, a warning light emitting layer 8 and a light shielding layer 9.

The transparent sheet lens 7 is made of polycarbonate, for example.

The warning light emitting layer 8 is printed on a part of the back surface 7a of the transparent sheet lens 7 and is red or orange.

The light-shielding layer 9 is printed on the upper surface 7b of the transparent sheet lens 7 so that the illumination light of the warning display light source 3 does not illuminate the picture mark 10 of the picture mark display section 2 described later, and is black. Etc. However, in order to allow the driver to visually recognize the light emission of the warning light emitting layer 8, the light shielding layer 9 is a region of the transparent sheet lens upper surface 7b which is directly above the warning light emitting layer 8 (hereinafter
It is called the display area. ) 7c is not formed.

At least the display area 7c on the upper surface 7b of the transparent sheet lens is subjected to diaphragm printing or the like so that external light is not reflected by the display area 7c.

Picture mark display section 2 The picture mark display section 2 comprises a transparent lens 11 and a picture mark 10 as shown in FIGS. 1, 2 and 4.

The transparent lens 11 is the transparent sheet lens upper surface 7
It is arranged in b. The transparent lens 11 has a flat plate shape, and a reflection surface 12 for bending the illumination light of the light source 4 for displaying the picture mark from below at a substantially right angle and guiding it to the central portion is formed on the peripheral portion thereof. .. Also, the transparent lens 1
A vertical through hole 13 is formed in a part of 1.
The through hole 13 is for exposing the display area 7c when the transparent lens 11 is provided on the transparent sheet lens upper surface 7b. The end face forming the through hole 13 is such that the illumination light that has reached the end face through the inside of the transparent lens 11 is reflected by the end face, in other words, the illumination light is emitted from the end face and illuminates the display area 7c. In order to prevent this, the inclined surface 14 is formed at an appropriate angle.

On the other hand, the picture mark 10 is printed on the back surface 11a of the transparent lens 11. The picture mark 10 is the character "BRAKE" in the present embodiment.

The warning display light source 3, the picture mark display light source 4, the light shielding case 5, the light shielding cover 6 and the warning display light source 3 are disposed inside the light shielding case 5 on the back side of the warning display portion 1. The light source 4 for displaying the picture mark is arranged by an appropriate mounting means (not shown) at an appropriate position where the illumination light can enter the peripheral portion of the transparent lens 11. The light-shielding case 5 is used as a mounting member for the warning display light source 3, and is used for illumination light of the warning display light source 3 and the picture mark display light source 4.
The function of preventing interference with the illumination light of the. Shading cover 6
Is arranged so as to cover the peripheral portion of the transparent lens 11.

Next, the operation and effect of the vehicular warning display device 100 having the above-described structure will be described.

Illumination light from the light source 4 for displaying the picture mark is incident on the transparent lens 11. The illumination light incident on the transparent lens 11 is bent at a substantially right angle on the reflecting surface 12, is guided to the central portion of the transparent lens 11, and illuminates the picture mark 10.

The illumination light reaching the inclined surface 14 of the through hole 13 is reflected by the inclined surface 14 and absorbed by the light shielding layer 9 of the transparent sheet lens 7. Therefore, it is possible to prevent the illumination light from passing through the inclined surface 14 and irradiating the warning light emitting layer 8 and prevent a problem that an undesired warning display is displayed at the time of displaying the picture mark.

On the other hand, the illumination light of the warning display light source 3 illuminates the warning light emitting layer 8. Although the illumination light is also incident on the light-shielding layer 9, this illumination light is absorbed by the light-shielding layer 9 and therefore does not pass through the transparent lens 11 and leak to the outside.

When the warning display device 100 is irradiated with strong external light during the warning display, the external light is scattered by the display area 7c of the transparent sheet lens 7 printed by diaphragm printing, so that the warning light emitting layer is formed. 8 does not cause a decrease in brightness.
