Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a configuration of a vehicle display device according to an embodiment of the present invention, FIG. 2 is a bottom view, and FIG. 3 is a side view.

  As shown in FIG. 1, this vehicular display device is provided in an instrument panel provided in the vicinity of a vehicle driver's seat, and includes a speedometer 1, a tachometer 2, a fuel gauge 3, and a thermometer 4 as instruments in order from the right side. Is provided. Each of the meters 1 to 4 has a pointer 11, and when the pointer 11 rotates and indicates a numerical value written on the dial 16 of the meter, various data are notified to the driver of the vehicle. be able to.

Further, as shown in FIG. 2 , each of the meters 1 to 4 is fixed to the same mounting plate 15. Each of the instruments 1 to 4 includes a dial 16 that includes a transparent acrylic plate (light guide plate) 12 and a design display plate 13 provided on the front side of the acrylic plate 12.

The acrylic plate 12 is composed of a flat surface portion 12b arranged in parallel to the mounting plate 15 and a peripheral surface portion 12a formed around the flat surface portion 12b. They are arranged at a predetermined angle. That is , the peripheral surface part 12a which each meter 1-4 has is arrange | positioned at a slight angle (1-2 degree) toward the left-right direction. That is, the circumferential surface portion 12a is inclined in the thickness direction of the dial 16 as it goes from one end to the other end along the circumferential direction. And the acrylic plates 12 of the instruments 1 to 4 adjacent to each other are partially overlapped.

Also, design display board 13, as shown in FIG. 2, is provided on the plane portion 12b of the acrylic plate 12. Further, each dial 16 is cut out at the right end face along the outer peripheral shape of the peripheral surface portion of the dial 16 adjacent to the right side, as indicated by symbol S in FIG. Therefore, a part of the right side of the design display board 13 of the meter 2 adjacent to the left side can be seen through from the peripheral surface portion 12a on the left side of the meter 1, and a stereoscopic effect can be obtained.

  A plurality of lighting LEDs (illuminating means) 14 are attached to the end surface on the inner side of the acrylic plate 12, and the LED 14 is turned on to irradiate light into the transparent acrylic plate 12. The entire inside of the acrylic plate 12 is lighted and the entire dial 16 including the design display board 13 is lighted.

  Next, an operation of the vehicle display device according to the present embodiment configured as described above will be described. When the LED 14 provided in each of the meters 1 to 4 is turned on in conjunction with turning on the ignition switch of the vehicle, the light emitted from the LED 14 is diffusely reflected in the acrylic plate 12, and the entire acrylic plate 12 is brightly lit. To do. At this time, since many irregular reflections occur at the outer peripheral surface of the acrylic plate 12, the peripheral portions 1a to 4a (see FIG. 1) of the respective instruments 1 to 4 shown in FIG.

  Furthermore, since the peripheral surface part 12a of the acrylic board 12 which each meter 1-4 has has transparency, the design display board 13 of the dial 16 used as the back surface of the part arrange | positioned mutually overlapping, It can be seen through, and a novel display form with a three-dimensional effect can be obtained.

  Thus, in the vehicular display device according to the present embodiment, when all the four instruments 1 to 4 are lit, the outer peripheral portion of the acrylic plate 12 is lit and looks conspicuous. It can be easily determined, and the pointer positions of the meters 1 to 4 can be easily read.

  In addition, among the meters 1 to 4 adjacent to each other, a part of the dials 16 is overlapped, and the peripheral surface portion 12a of the acrylic plate 12 is transparent. Since the driver's line of sight is entered, the entire display device can have a three-dimensional effect and transparency, not only can the visibility be improved, but also an extremely novel display mode full of realism can be realized. it can.

  Furthermore, since a meter such as the speedometer 1 or the tachometer 2 that needs to be frequently viewed during driving is displayed in three dimensions, it is possible to provide a display mode that is easy for the driver to use.

  Furthermore, since the peripheral surface portion of the acrylic plate 12 included in the four meters 1 to 4 is inclined by a slight angle with respect to the mounting plate 15 in the left-right direction, the adjacent dials 16 are arranged in an overlapping manner, The length of the entire display device in the depth direction is not increased, and the overall size can be reduced.

  Moreover, since the part hidden by the dial 16 design display board 12 of the adjacent instrument dial 16 is cut out of the dial 16 of each instrument 1 to 4, the material can be reduced, and the entire apparatus can be reduced in size and weight. Can be achieved.

  The vehicle display device of the present invention has been described based on the illustrated embodiment, but the present invention is not limited to this, and the configuration of each part is replaced with an arbitrary configuration having the same function. be able to.

  For example, in the above-described embodiment, the dials 12 included in the four meters 1 to 4 are inclined to overlap the dials 16 adjacent to each other, but there is a margin in the length in the depth direction. Alternatively, the dials 16 of the four meters 1 to 4 may be arranged in parallel with each other at positions shifted in the front-rear direction so that adjacent dials 16 overlap each other.

  This is extremely useful for improving the visibility of various instruments provided in the instrument panel of the vehicle.
