Description

[Detailed Description of the Invention] This invention relates to an improved structure of a display device installed in instruments for vehicles, ships, or agricultural machinery.

2. Description of the Related Art In general, automobiles, motorcycles, etc., for example, are equipped with a display device that intensively informs the driver of the failure location of each part or the operating status of various devices.

This type of general display device will be explained using FIGS. 1 to 3. Reference numeral 1 denotes an instrument case made of synthetic resin that is attached to a suitable location on the vehicle. A dial plate 3 is fixed in the instrument case 1 above the instrument body 2, and a dial 3 is fixed to the instrument body 2 to indicate the indication of the pointer 4 formed on the instrument body 2. It is read by comparing it with the scale and numerical values provided on the surface of the dial plate 3.

In addition, the instrument case 1 has the same number of display items as the number of display items, such as display of the operating status of various equipment of the vehicle, such as display of turn signal operation, display of engine oil pressure status, and display of vertical status when headlights are on. A cylinder 5 is provided which is partitioned and isolated from each other, each illumination light 6 is attached to the lower part of this cylinder 5, and each display lens 7 is fitted on the surface side of the instrument, that is, above each cylinder 5. Letters and symbols such as OIL, BEAM,
A display section 8 such as TURN is formed.

In this case, the display section 8 is formed by printing a colored transparent layer 9 of the same color as the display lens 7 on at least the part that will become the display section 8 on the front side of the dial plate 3, and at least on the surface of the colored transparent layer 9. A semitransparent layer 10 of white or the like is formed by printing or the like, and a light shielding layer 11 of black or the like that blocks the light rays of the illumination lamp 6 is formed on this semitransparent layer 10 by printing or the like in areas other than the part that will become the display section 8. ing.

Further, a glass plate 12 is disposed above the instrument case 1 to prevent dust from entering the case 1, and the instrument case 1 and the glass plate 12 are fixed.

Therefore, normally, the white color of the semi-transparent layer 10 printed on the dial plate 3 can be seen in the display section 8 corresponding to each display lens 7. Further, the illumination lamp 6 is turned on by the operation of various devices in the vehicle, and the display lens 7 is illuminated and displayed by this illumination beam. appears bright and visible, allowing the driver to clearly see the situation of the vehicle. In this case, the display section 8 for characters, pictures, symbols, etc. changes from white display to the color of the colored transparent layer 9 and is brightly illuminated, making it easier to read whether or not the vehicle equipment is operating.

By the way, in the case of the above-mentioned display device, since the display lens 7 and the display section 8 are illuminated at the same time, the operating state can be easily determined, but on the other hand, the display section 8 provided on the dial plate 3 is The process becomes complicated,
There is a tendency for manufacturing man-hours to increase and costs to rise.

This idea solves the above problem by installing an illumination light at the bottom of the cylinder, and a display board on the front side of the cylinder, and a display lens for display or warning on this display board. The color of the display lens itself can be utilized by attaching and fixing the display lens and placing at least a part of the display lens protruding from the back side of the display section for pictures, characters, symbols, etc. provided on the display board. The display unit is illuminated by the display unit, and the printing process for the display unit is simplified to construct a simple display device.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6.

Inside the case 20 of this instrument device is an instrument body 21.
is housed and fixed, and a dial plate 22 is fixed above the meter body 21, so that the instructions of the pointer 23 formed on the meter body 21 can be read by comparing with the scale and numerical values provided on the surface of the dial plate 22. ing.

In addition, the instrumentation device is divided into the same number of display items as the number of display items, such as display of the operating status of various equipment of the vehicle, such as the operation display of the direction indicator, the display of the engine oil pressure status, and the display of the vertical status of the headlights. A cylindrical body 24 is provided, which is isolated from the cylindrical body 24. Below the cylindrical body 24, each illumination light 25 is attached, and on the surface side of the instrument, that is, on the upper side of each cylindrical body 24, a dial 22 is provided.
A colored display lens 26 is attached and fixed to a window portion formed in a notch.

The dial 22 also includes the display lens 26.
A display section 27 with letters, symbols, or pictures such as TURN, OIL, BEAM, etc. is provided correspondingly. In this case, the display section 27 is provided with a semi-transparent layer 28 of white or the like on the front side of the dial plate 22, and then a black color that blocks the light rays of the illumination lamp 25 is placed on the semi-transparent layer 28 other than the part that becomes the display section 27. A light shielding layer 29 such as the above is provided.

Therefore, the display section 27 provided on the dial plate 22
The display lens 26 is located at a position corresponding to the back surface.
A protruding portion 26A is provided that extends integrally from the top.

Note that a transparent glass plate 3 is provided on the front side of the instrument case 20 to prevent dust from entering the case 20.
0 is placed.

In the above configuration, in a normal state, that is, in a non-operating state of the vehicle equipment, the display lens 26
The display section 27 is not illuminated and the white color of the semi-transparent layer 28 can be seen on the display section 27. Further, when the vehicle equipment is in operation, the illumination lamp 25 is turned on, and the display lens 26 and the display section 27 are illuminated by the irradiated light.
and is displayed with lighting. At this time, the display lens 26
The color of the protruding portion 26A, for example, red, which extends integrally from the projection portion 26A, is transmitted by the irradiation light beam of the illumination lamp 25,
The transmitted red color illuminates the display section 27, and the display section 27 is illuminated in red from the surface of the dial plate 22, thereby making it possible to clearly read the operating status of the vehicle equipment.

Further, in this case, by using a part of the display lens 26, it is possible to provide a simple configuration means. That is, the protruding portion 2 is integrally attached to the display lens 26.
By forming 6A, colored illumination display can be easily performed and the function of a colored filter of the display section 27 can be achieved.

In addition, the display lens 26 can be attached and fixed to the dial 22 and the protrusion 26A as a colored filter of the display section 27 can be attached and fixed at the same time, and a display device with a small number of parts and easy to assemble can be constructed. be able to.

In the above-described embodiment, the protruding portion 26A is formed integrally with the display lens 26, and the protruding portion 26A is provided in the same color as the display lens 26.
From the beginning, a colored resin lens is placed at a location corresponding to the protrusion, a resin display lens is integrally molded onto this color lens, and the display lens is attached and fixed to the dial (display board). At the same time, the color lens may be disposed corresponding to the back side of the display section.

In this case, the color of the display lens, for example, blue, is illuminated and displayed by the irradiation light from the illumination lamp, and at the same time, the color of the color lens, for example, red, is transmitted and illuminated by the light, so that the display part is illuminated in red. By appropriately setting the display lens and the display section to the same color or different colors, it becomes possible to perform illumination display.
