Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a panel display device for electrical equipment such as automobile meters and switches.

[Prior art]

Conventionally, for example, in automobiles, various meters and various control switches installed on the instrument panel etc. have been provided with display parts showing scales and switch names. The front wall of the knob, which is the panel, is made of a translucent material, the surface of the front wall of the knob is colored black by printing, and the display part in the form of letters and symbols to represent the switch name is painted white. Further, the back side of the front wall of the knob is printed in a bright color so that the front wall of the knob shines in the bright color at night using a lamp provided on the back side. However, such two-color printing on the surface of the front wall of the knob has the disadvantage that it is time-consuming and increases the cost.

[Purpose of invention]

The present invention has been made in view of the above circumstances, and its purpose is to provide a panel display device that can simplify the coloring work and reduce costs.

[Summary of the idea]

In the present invention, the case has a structure that is shielded from light except for the opening and has a light emitter inside, a panel provided at the opening of the case is formed to have light regulating properties, and a display section is attached to the panel. In addition, a bright color layer is formed on the back side of the panel, so that printing on the panel surface can be done only in the color layer, and the visibility of the display area is improved. It is designed to improve the

〔Example〕

Hereinafter, one embodiment of the present invention applied to, for example, a switch for an air conditioner in an automobile will be described with reference to the drawings. Reference numeral 1 denotes a case with an open front, which is made of a non-light-transmitting material, for example, plastic, and the interior thereof is shielded from light except for the opening 1a. 2,
2 is a pair of terminals disposed on the rear wall 1b of the case 1 by integral molding with the rear wall 1b of the case 1; is inserted into. 3, 3 are contact plates extending from the base ends of the terminals 2, 2 in a standing state and a hanging state, respectively; 4 is a contact disposed in the case 1 so as to be able to come into contact with and separate from the contact plates 3, 3; ,
On the other hand, reference numeral 5 denotes a knob slidably provided in the opening 1a of the case 1. It is constructed by attaching a panel 7 made of, for example, plastic and having a light property and a light adjustment property. That is, as shown in FIG. 3, the panel 7 includes, for example, a translucent substrate 14,
The resin layer 15, which is non-transparent and has a thickness of 0.1 mm, has a thickness of approximately 0.2 mm.
It is configured to be buried at intervals of mm, and has a light regulating property that blocks light other than approximately straight light. Reference numeral 8 denotes a color layer section, which is attached by printing in a so-called cut-out state so that a display section 9 in the shape of the letters "A/C" remains on the surface of the panel 7, as shown in Figure 2. It is something. Furthermore, a bright color layer portion 13 is formed on the back surface of the panel 7 by, for example, printing. Reference numeral 10 denotes a lamp serving as a light emitting body disposed inside the case 1, and this is adapted to be turned on when the knob 5 is pressed. 11 is this lamp 1
This is a cap that is covered with 0, and has a so-called bright color that is highly visible. Reference numeral 12 denotes a spring interposed between the knob 5 and the contact 4, which transmits the movement of the knob 5 to the contact 4 so that the contact 4 is connected to the contact plates 3, 3 of the terminals 2, 2.
It is intended to be brought into contact with. In addition, knob 5 and case 1
Although not shown, a locking mechanism is provided between the knob 5 and the knob 5, so that when the knob 5 is pressed once, it locks at that position, and when the knob 5 is pressed again, the lock is released. ing. The switch A having the above structure is installed in an instrument panel (not shown) of an automobile.

In the above configuration, when the lamp 10 is turned on, the light is emitted from the display section 9 through the bright color layer section 13 on the back surface of the panel 7, so that visibility is extremely high. In this case, since the case 1 is configured to be light-shielded except for the opening 1a, there is no leakage of light.

As described above, according to this embodiment, since the display portion 9 is formed in the color layer portion 8 in a character-excluded state, the printing performed on the panel 7 is performed on the color layer portion 8 in which the display portion 9 is in the character-exclusion state.
Therefore, there is no need to perform two-color printing on the surface as in the conventional method, which simplifies the coloring work and reduces costs.

Moreover, according to this embodiment, the case 1 is structured to block light except for the opening 1a thereof, and the lamp 10 is provided inside the case 1 to illuminate the display section 9 in the character-excluded state. Good visibility of the portion 9 can be ensured, and the problem of light leaking to the outside of the case 1 can also be prevented. Furthermore, since the bright color layer section 13 is formed on the back surface of the panel 7, its visibility can be further improved.Furthermore, since the panel 7 is formed to have light regulating properties, the lamps emitted from the display section 9 can be The light of 10 can be directed only in a certain direction, and the diffusion of light can be reliably prevented and the display shape of the display section 9 will not be altered.Moreover, at night, the light enters the eyes directly. Furthermore, there is no reflection of light on the windshield of a car, making it extremely safe to drive a car at night.

In the above embodiment, the color layer portion 8 is attached to the panel 7 by printing, but this color layer portion 8 may be attached by printing to the surface of a thin transparent film or a thin layer of a similar color. From the film material to the display section 9
These films may be formed by punching and then used by polymerizing them on the surface of the panel. Further, in the above embodiments, the present invention has been described as being applied to an air conditioner switch, but the present invention can also be widely applied to other electrical equipment such as various meters. Further, when the panel display device of the present invention is applied to a plurality of electrical components in an automobile instrument panel, it is more convenient if the color of the cap 11 in the above embodiment is made different for each electrical component.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications within the scope of the invention.

[Effects of the invention] As is clear from the above description, the present invention forms a display section in the form of cut-out characters in the color layer attached to the panel surface, and displays the display using a light emitting body provided inside the case. Since the parts are made to glow, only the color layer parts need to be printed on the panel, which simplifies the coloring work and reduces costs. Since the structure is such that light is shielded from the outside of the screen, it is possible to prevent light leakage, and the panel is structured to have light regulating properties, so that it is possible to prevent the diffusion of light emitted from the display section, thereby changing the display shape of the display section. Moreover, together with the formation of a bright color layer on the back of the panel, visibility can be greatly improved, and the light from the display section does not directly enter the eyes, making it particularly advantageous for the present invention. When the panel display device is used for automobile switches and meters, there is no reflected light on the windshield, and there is no problem with night driving, resulting in extremely high safety.
