Description

  The present invention relates to a vehicle instrument.

  A vehicle instrument that displays the traveling speed of a vehicle is configured by arranging a light source behind a dial so that it can perform light emission display at night or the like (see Patent Document 1). In such a vehicle instrument, in some countries, in addition to a predetermined instrument display such as the traveling speed of the vehicle, it may be necessary to display an alphanumeric symbol display for vehicle certification. There are certain provisions regarding the display for vehicle certification, such as display within the vehicle speed display design, non-luminous display, and the like. On the other hand, since the display for vehicle certification is a foreign material that is not compatible with the design of the entire instrument, there is a demand to make it inconspicuous while making it visible.

Japanese Patent Laid-Open No. 9-96546

  Conventionally, such a dial plate for a vehicle instrument has a translucent black printed layer formed on the back surface of the transparent base material as a non-transparent printed layer excluding the display area for vehicle certification. A white solid print layer having a non-transparent black solid print layer is formed thereon. The dial is arranged so that the black solid print layer side is the light source side. As a result, the alphanumeric symbol display for vehicle certification is visually recognized by looking at the white solid printed layer having translucency from the extracted region of the black opaque translucent printed layer. It is visually recognized in white that is not so noticeable, and at night, the opaque black solid print layer blocks light from the light source, so it does not emit light and is almost invisible. On the other hand, in the instrument display area for displaying the necessary instrument such as the traveling speed of the vehicle, a black-out printed layer for instrument display is formed on the back surface thereof, and a solid print of a predetermined color having translucency is formed thereon. Layers are formed, and the dial is arranged so that the light from the light source strikes from the solid printed layer side. As a result, the instrument display is visually recognized in the form of looking at the solid print layer of a predetermined color from the black blank print area during the daytime, and light from the light source is transmitted through this blank area at night, and the predetermined print on the solid print layer is displayed. Visible in a state of emitting light in color.

  As described above, in the current vehicle meter that displays alphanumeric symbols for vehicle certification, the vehicle certification display is made difficult to see by printing different from other meter displays. And there is a problem that more costs and man-hours are required for the purpose of making it difficult to see.

  An object of the present invention is to reduce costs and man-hours of a vehicle instrument that displays a vehicle certification.

A vehicle instrument for solving the above problems is
An instrument for vehicles in which light emission of the instrument display is enabled by irradiating the back of the dial on which the instrument display is printed and light emission display of the instrument display is possible, and the vehicle certification display is in the form of non-light emission display There,
On the base material having translucency, a dial having a vehicle certification display portion in which a non-light-transmissive printing layer is printed in a predetermined color in a form that leaves the region for vehicle certification display,
A reflector that is arranged behind the dial and is opaque to a color different from the predetermined color that blocks light from the light source toward the vehicle-certifying display portion of the dial;
The vehicle authorization display section is displayed by a non-light emitting display for visually recognizing the color of the reflector from a non-formation area of the print layer.

  A dial plate of a conventional vehicle instrument has a black blank printed layer for a vehicle certification display, a white solid printed layer thereon, and a light thereon. It has been common technical knowledge to form a three-layer structure including a black solid print layer for absorption. In this conventional structure, focusing on the fact that the light shielding function of the black solid print layer for light absorption is also provided in the reflector disposed behind the dial, the conventional black solid print layer is excluded, By utilizing the color of the reflector of the vehicle instrument so that it can be seen as it is, the conventional white solid printed layer is also eliminated. As a result, the conventional two-layer printing layer of black solid printing layer and white solid printing layer and the printing process are no longer necessary, and it is possible to reduce the man-hours and costs associated with them.

  On the other hand, a dial has a meter display part on which a scale and a numerical display for displaying the speed of a vehicle are made on the translucent base material with the above-mentioned display part for vehicle recognition. The instrument display unit is printed and formed on the base material so that a predetermined non-transparent print layer is formed while leaving a predetermined instrument display area, and at least the remaining instrument display area is colored with a predetermined color. A translucent print layer, and a predetermined design display is formed by the print layer. A light guide unit that guides light from the light source is provided behind the instrument display unit to enable light emission display on the instrument display unit. When manufacturing such a dial plate for a vehicle instrument, first, a printed layer of a predetermined color having translucency constituting the instrument display unit is first printed and formed on the base material, and then the impermeability in the instrument display unit is formed. A light print layer and a non-light-transmitting print layer in the vehicle authorization display unit are printed. In this case, the dial is efficiently manufactured by printing and forming both the opaque printing layer in the instrument display unit and the opaque transmission layer in the vehicle certification display unit as the same printing layer. be able to.

The figure which showed a part of meter display surface of the meter for vehicles. The figure which showed the enlarged view of the display area for vehicle recognition in the instrument display surface of FIG. 1, and its AA sectional drawing. The figure which showed the enlarged view of the meter display area in the meter display surface of FIG. 1, and its BB sectional drawing. The figure which showed the enlarged view of the display area | region for vehicle recognition in the meter display surface of the meter for vehicles different from FIG. 1, and its CC sectional drawing.

  The vehicle meter 100 of FIG. 1 has a meter display unit 102 on which a predetermined meter display such as a speed meter 102A for displaying the speed of the vehicle and a fuel remaining amount meter 102B for displaying the remaining fuel is displayed on the meter display surface 100a. Have In addition to the instrument display unit 102, the vehicle instrument 100 includes a display unit 101 (hereinafter referred to as a vehicle certification display unit 101) composed of predetermined character symbols for vehicle certification. On the dial plate 10 in FIG. 1, both the vehicle authorization display unit 101 and the instrument display unit 102 are provided.

  As shown in FIGS. 2 and 3, the vehicle instrument 100 includes a dial plate 10, a light source 5 that irradiates the back surface of the dial plate 10, and a reflector 4 disposed between the dial plate 10 and the light source 5. Have. Here, the light source 5 is an LED mounted on the wiring board 6 and is disposed behind the dial 10. The light source 5 may use another type of light source different from the LED, or may be configured such that the light source 5 is disposed at another position and the light is guided to the back surface of the dial plate 10 by a light guide member.

  As shown in FIG. 2, the dial plate 10 has a base material 2 having translucency. The base material 2 is a transparent material or a semi-transparent material, and can be a plate-like material or a sheet-like material. Further, the dial plate 10 has print layers 3 and 7 that form the vehicle authorization display unit 101 and the instrument display unit 102 printed on the base member 2 together with the base member 2.

  As shown in FIG. 2, the vehicle authorization display unit 101 has a shape in which an area (here, an area forming the alphanumeric symbol E114) 3h that is a predetermined vehicle authorization display is left on the base material 2. The printed layer 3 formed by printing is formed. The print layer 3 is a predetermined color and opaque layer. Although the color of the printing layer 3 can be selected as appropriate, the printing layer 3 here is a printing layer having a color different from white having high light reflectivity. Specifically, the printing layer 3 here is a black printing layer that forms a light absorption color.

  As shown in FIG. 3, the meter display unit 102 is printed on the base material 2 so as to leave a predetermined meter display area (here, a meter scale or a number area) 3h. The translucent print layer 3 and the translucent print layer 7 printed to color the remaining instrument display area 3h are formed.

  The printing layer 3 of the instrument display unit 102 here is the same layer as the printing layer 3 of the vehicle certification display unit 101, and here is a black printing layer that forms a light absorption color. On the other hand, the printed layer 7 of the instrument display unit 102 is a colored layer for realizing instrument display in a highly designable form within the instrument display surface 100a, and has translucency. The print layer 7 is only required to be formed in at least the instrument display region 3h, but here it is printed on the entire instrument display unit 102 in consideration of being covered with the black print layer 3. The printing layer 7 can be a chromatic printing layer, for example, a monochrome printing layer such as orange or blue, a printing layer having a plurality of colors, a multilayer printing layer in which a plurality of monochrome layers are stacked, or the like. When the light from the light source hits, the light is emitted in that color.

  The reflector 4 is disposed behind the dial plate 10 on which the vehicle authorization display unit 101 and the instrument display unit 102 are formed. The reflector 4 is a light-impermeable member having a color different from that of the printing layer 3, and a white polypropylene material is used here.

  As shown in FIG. 3, a light guide 8 that guides light from the light source 5 is provided behind the instrument display unit 102. Light emitted from the light source 5 is guided by the light guide unit 8 and applied to the back surface of the instrument display unit 102, so that the instrument display unit 102 can perform light emission display. More specifically, the non-formation region 3h of the print layer 3 in the instrument display unit 102 can be displayed in a light emitting manner. The light guide unit 8 may be any light source 5 provided so that the light from the light source 5 is directed to the back of the instrument display unit 102. For example, a prism light guide disposed facing the back of the instrument display unit 102, A through-hole or the like formed through the reflector 4 can also be used.

  On the other hand, behind the vehicle authorization display unit 101, as shown in FIG. 2, the light guide unit 8 that guides the light from the light source 5 is not provided. For this reason, the light of the light source 5 toward the vehicle authorization display unit 101 of the dial plate 10 is blocked by the non-transmissive reflector 4 and does not irradiate the vehicle authorization display unit 101. Therefore, the display of the vehicle authorization display unit 101 is a non-luminous display in which the white color of the reflector 4 exposed from the non-formation region 3h of the print layer 3 is visually recognized in the vehicle authorization display unit 101. Since the non-light-emitting display for vehicle authorization 101 can hardly be visually recognized at night, the light-emitting display with high design of the instrument display 102 is not disturbed. Moreover, the display part 101 for vehicle recognition only sees the white of the reflector 4 also in the daytime. Since the printing layer 3 is a black layer having light absorption and has a certain height, the white reflected light reflected by the reflector 4 at the back in the non-formation region 3h is one of them. The portion is absorbed by the printing layer 3 surrounding the non-forming region 3h, resulting in a dull and inconspicuous display.

  When the dial 10 of the vehicle instrument 100 is manufactured, first, the printed layer 7 having translucency constituting the instrument display unit 102 is printed on the base material 2, and then the instrument display unit is formed. What is necessary is just to carry out the printing formation of the opaque translucent printing layer 3 over both 102 and the display part 101 for vehicle recognition. In this case, since the opaque printing layers 3 and 3 in both the instrument display unit 102 and the vehicle certification display unit 101 can be printed and formed as a single printing layer 3, the dial plate 10 is efficiently manufactured. can do.

  The above embodiments are merely examples. The present invention is not limited to this, and various modifications such as additions and omissions can be made based on the knowledge of those skilled in the art without departing from the scope of the claims.

  Hereinafter, other examples and modifications will be described. However, the same parts as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. It should be noted that the above embodiment and the following embodiment or the following modification can be combined as appropriate within a range that does not cause technical contradiction.

  In the above embodiment, the dial plate 10 is formed with the non-transparent print layer 3 on the reflector 4 side, as shown in FIG. 3, as shown in FIG. The opaque printing layer 3 forming the vehicle authorization display unit 101 may be formed on the side opposite to the reflector 4. In the case of FIG. 4, since the distance from the surface of the reflector 4 to the opening of the non-formation region 3h of the printing layer 3 is longer than in the case of FIG. 2, the white reflection reflected on the reflector 4 at the back in the non-formation region 3h. The light is more difficult to leak out from the opening of the non-formation region 3h, resulting in a more dull and inconspicuous display.
