Description

  The present invention relates to an indicator device that is incorporated in a vehicle instrument such as an automobile, a motorcycle, an agricultural machine, or a construction machine and displays various information by light emission.

  As this type of indicator device, for example, the one described in Patent Document 1 below is known. This indicator device is incorporated in a panel body called a look-back plate surrounding the display composed of an analog meter in a meter. A circuit board, a light source mounted on the circuit board, and a circuit board A case having a light box disposed and containing a light source; a display plate disposed on an opening side of the light box; and a panel body made of a translucent material covering a front side of the case including the display plate. ing. Marks indicating the remaining amount of fuel, high beam, and turn direction are printed on the display board, and these marks are transmitted and illuminated when the light source is turned on, and the light passes through the panel body and is visually recognized.

  However, the indicator device described in Patent Document 1 requires a display plate for forming a mark that emits light upon receiving light from a light source, and the cost is increased accordingly.

  Therefore, the present invention focuses on the above-described problems and aims to provide an indicator device capable of reducing the cost.

The present invention includes a circuit board, a light source mounted on the circuit board, a front plate portion located in front of the circuit board and facing the observer, and a front opening at a predetermined portion of the front plate portion. In the indicator device, comprising: a cylindrical portion that is continuously formed on the circuit board so that the rear side opening faces each other; and the case that houses the light source in the cylindrical portion. A panel body made of a translucent synthetic resin having a smoke-like appearance that is separate from the case disposed so as to cover the front plate portion is included in the case by insert molding, The shape of at least the front opening in the overall shape is made to correspond to the shape of the display design to be lit and displayed by turning on the light source.
By comprising in this way, since the structure of cylinder part itself forms the external shape of a display design, a display board can be made unnecessary and cost reduction can be achieved.
Moreover, since the adhesiveness of the said panel body and the said case improves by insert molding, display quality can be improved.

In the invention, it is preferable that the panel body has a semi-transmissive layer corresponding to the shape of the front opening.
With this configuration, it is possible to prevent the inside from being seen through.

  ADVANTAGE OF THE INVENTION According to this invention, the display apparatus which can make a display board unnecessary and can achieve a cost reduction can be provided.

The front view of the indicator apparatus (at the time of light source lighting) by the 1st Embodiment of this invention. AA sectional drawing of FIG. 1 (hatching is abbreviate | omitted). The front view at the time of removing a panel body. Sectional drawing of the indicator apparatus by the 2nd Embodiment of this invention (hatching is abbreviate | omitted).

(First embodiment)
As shown in FIGS. 1 to 3, the indicator device according to the first embodiment of the present invention is incorporated into a part of a vehicle meter, for example, and includes a circuit board 1, a light source 2, a case 3, A cover 4 and a panel body 5 are provided.

  The circuit board 1 is, for example, a hard circuit board, and a light source is mounted on a circuit pattern (not shown) formed on the observer-side plate surface.

  The light source 2 is composed of a light emitting diode, for example, and displays a turn indicator mark by light emission.

  The case 3 is made of, for example, black light-shielding synthetic resin, and includes a front plate portion 31 and a cylindrical portion 32.

  In the case 3, the front plate portion 31 is formed of a plate-like portion located in front of the circuit board 1 and facing the observer.

  The cylindrical portion 32 includes a front opening 33 that faces a predetermined portion of the front plate portion 31 and a rear opening 34 that faces the circuit board 1, and accommodates the light source 2.

  Since the cylindrical portion 32 is formed as an arrow column corresponding to the shape S2 of the arrow-shaped turn indicator mark M which is a display design to be lit and displayed when the light source 2 is turned on, the shape S1 of the front opening 33 is also turned. This corresponds to the shape S2 of the indicator mark M, and when the light source 2 is turned on, the cylindrical portion 32 (front opening 33) emits light in the shape of the turn indicator mark M. In addition, it is not necessary to make the whole shape of the cylinder part 32 correspond to the turn indicator mark M in this way, and it is sufficient that at least the front opening 33 corresponds.

  The cover 4 is made of, for example, transparent or a synthetic resin having an appropriate color, and forms a space for housing the circuit board 1 with the case 3.

  The panel body 5 is made of, for example, a translucent synthetic resin having a smoke-like appearance, and is insert-molded with respect to the case 3 so as to cover the front plate portion 31 including the front opening portion 33 of the cylindrical portion 32. .

  Since the panel body 5 is smoke-like, the panel body 5 itself looks smoke-like when the light source 2 is turned off. On the other hand, when the light source 2 is turned on, the cylindrical portion 32 that emits light in the form of the turn indicator mark M appears to be transmitted, whereby the turn indicator mark M is emitted and displayed.

  As described above, in the present embodiment, the circuit board 1, the light source 2 mounted on the circuit board 1, the front plate portion 31 positioned in front of the circuit board 1 and facing the observer, and the front plate A case 3 that has a front opening 33 at a predetermined portion of the portion 31 and a cylindrical portion 32 that is continuously formed so that the rear opening 34 faces the circuit board 1 and accommodates the light source 2 in the cylindrical portion 32. And a panel body 5 made of a translucent material disposed so as to cover the front plate portion 31 including the front side opening 33, the shape S1 of the front side opening 33 is defined as a light source. Since the structure of the cylindrical portion 32 itself forms the shape of the display design by making it correspond to the shape S2 of the turn indicator mark (display design) M to be lit and displayed by the lighting of 2, the display plate can be made unnecessary and the cost is reduced. Can achieve down .

  Moreover, in this embodiment, the panel body 5 and the case 3 are integrated by insert molding, so that the adhesion between the panel body 5 and the case 3 is improved, and in particular, the overlapping portion between the panel body 5 and the front plate portion 31. The display quality when viewed from the front can be improved.

(Second Embodiment)
As shown in FIG. 4, the indicator device according to the second embodiment of the present invention includes a panel body 5 provided with a semi-transmissive layer 51 corresponding to the shape of the front opening 33, and is thus configured. Thus, it is possible to prevent the inside (the light source 2, the cylindrical portion 32, and the circuit board 1) from being seen through.
