Description

  The present invention relates to a vehicle display device that can be used, for example, as a combination meter for an automobile.

  As a conventional vehicle display device, for example, there is a vehicle display device described in Patent Document 1. This vehicular display device has a first dial and a second dial arranged on the first dial in such a manner that pointer instruments of different types are stacked in the front-rear direction (depth direction). The first and second pointers are arranged so as to rotate along the front surface of the dial. In such a display device, the dial plate is fixed by being sandwiched between a dial plate on the front side of the dial plate and a case body on the back side of the dial plate.

JP 2008-89477 A

  However, since such a vehicle display device has a structure in which the dial is sandwiched and fixed between the dial plate on the front side of the dial and the case body on the back side of the dial, the number of parts used for fixing is small. In many cases, there are problems such as wobbling of parts when used in a vehicle due to a gap portion associated therewith, and a dial plate floating, and there is room for improvement in terms of earthquake resistance.

  Therefore, the present invention provides a first dial instrument having a first dial and a first pointer that rotates along the front surface of the first dial, a second dial, and a first dial And a second pointer instrument having a second pointer that rotates along the front surface of the second dial, and the second pointer instrument is partially stacked with the first pointer instrument. In the display device, the first pointer instrument includes a first case body for supporting the first dial, and the second pointer instrument supports the second dial. A second case body, the second case body extending toward the first case body and contacting the first case body; and the contact portion is formed on the first case body. An engaging portion that fits into the first case body in a contact state, and the first case body engages with the engaging portion. And it has a engaged portion.

  In the present invention, the second case body includes a holding portion that presses the first dial plate toward the first case.

  In the present invention, the abutting portion abuts on a predetermined portion of the first case body avoiding the first dial.

  ADVANTAGE OF THE INVENTION According to this invention, the display apparatus for vehicles excellent in earthquake resistance can be provided.

The front view of one Embodiment in this invention. AA sectional drawing same as the above (hatching is omitted). BB sectional drawing same as the above (hatching is omitted). Enlarged view of the main part of the opposition as above.

  Embodiments of the present invention will be described with reference to the accompanying drawings.

  The display device for a vehicle according to the present embodiment mainly includes a first pointer instrument 1, a second pointer instrument 2 arranged on the first pointer instrument 1, a circuit board 3, and a back cover 4. It is configured.

  As shown in FIGS. 2 and 3, the first pointer instrument 1 supports a first dial plate 11 having a first indicator portion 12 a on which a scale or the like is printed, and the first dial plate 11. It consists of a first case body 31 and a first pointer 12 that points to the first indicator portion 12a.

  The first dial plate 11 has a structure in which a central portion where a second dial plate to be described later is arranged is cut out. In the case of this embodiment, the first indicator portion 12a located on the left side in FIG. Is given by printing. The first pointer 12 indicating the first indicator portion 12a is attached to a first pointer shaft 12b extending from the circuit board 4.

  The first case body 31 is formed using, for example, white impermeable synthetic resin, and is disposed on the circuit board 4 accommodated in the back cover 5. The first case body 31 is provided with through holes 12c and 12d through which a first pointer shaft 12b of a stepping motor extending from the circuit board 4 side and a second pointer shaft described later pass.

  In addition, the first case body 31 is provided with three engagement holes 312 into which engaging portions to be described later are inserted, and three engaged portions 311 with which the engaging portions are engaged with each other (see FIG. 3). Not shown).

  As shown in FIG. 2, the second pointer instrument 2 includes a second dial plate 21 having a through-hole 22 c in which a central portion is hollowed out in a substantially circular shape, and a second dial plate 21 that supports the second dial plate 21. The case body 32 and a second pointer 22 indicating the second indicator portion 22a on which a scale or the like is printed. The second pointer 22 is attached to a second pointer shaft 22b of a stepping motor extending from the circuit board 4 side.

  The second case body 32 is formed using, for example, a white impermeable synthetic resin, and has an annular rib (abutment portion) on the periphery of the through hole 22c so as to have a space S at the center portion corresponding to the through hole 22c. ) 321 is formed to protrude toward the first case body 31. The annular rib 321 extends toward the first case body 31 so as to surround the rotation center of the second pointer 22. Further, the second case body 32 includes an engaging portion 323 outside the annular rib 321 and at a location corresponding to the engaged portion 311 provided in the first case body 31.

  The annular rib 321 avoids the first dial 11 when the second pointer instrument 2 is assembled to the first pointer instrument 1 by engaging the engaging portion 323 with the engaged portion 311. The first case body 31 is formed so as to abut on a predetermined location.

  Further, as shown in FIG. 4, the annular rib 321 is provided with a holding portion 322 extending from the annular rib 321 so as to surround the pointer cap 121 of the first pointer 12. The holding portion 322 is integrally formed with the annular rib 321, and when the second pointer instrument 2 is assembled to the first pointer instrument 1, the first dial 11 is attached to the first case body 31. It is formed so as to contact the side.

The circuit board 4 is a well-known hard print board made of, for example, a glass epoxy material, and the back cover 5 is made of, for example, a light shielding synthetic resin.

As described above, the present embodiment includes the first pointer instrument 1 including the first dial plate 11 and the first pointer 12 that rotates along the front surface of the first dial plate 11. 2 dial plate 21 and a second pointer meter 2 having a second pointer 22 that rotates along the front surface of the second dial plate 21, and the second pointer meter 2 is the second pointer meter 2. In the display device that is partially stacked with one pointer instrument 1, the first pointer instrument 1 includes a first case body 31 for supporting the first dial plate 11, and a second pointer The meter 2 includes a second case body 32 that supports the second dial plate 21, and the second case body 32 extends toward the first case body and is in contact with the first pointer instrument 1. (Abutting portion) 321 and a plurality of fittings that fit into the first case body 31 in a state where the abutting portion is in contact with the first case body. Since the first case body 31 has the engaged portion 311 that engages with the engaging portion 323, the components can be assembled without increasing the number of components. Therefore, it is possible to provide a display device that is excellent in earthquake resistance.

Further, in the present embodiment, since the second case body 32 includes the restraining piece 322, the first dial 11 can be prevented from floating even if the display device is shaken by vibration.

In the present embodiment, the annular rib 321 is provided so as to contact the first case body 31 while avoiding the first dial plate 11, so that the first dial plate 11 or the second case body is vibrated by vibration. Even if 32 is shaken, it is possible to prevent the annular rib 321 from rubbing against the first dial 11 and generating dust.
