Description

  The present invention relates to a vehicle display device using a display.

  For example, there is a combination meter that performs various displays in a vehicle in which information that has been displayed on an analog instrument is digitally displayed on a liquid crystal display or the like (for example, Patent Documents 1 and 2). The display contents are merely switched as appropriate on a liquid crystal display or the like, and there is an aspect that the display is flat and lacks clarity.

Therefore, the present applicant arranges a ring-shaped display partition member with a lens along the display surface in front of the display surface of the liquid crystal display, and this ring-shaped display partition member is driven by a drive source such as a motor to generate liquid crystal. A vehicular display device has been proposed in which a linear movement is made on the display surface of the display so that a partial region on the display surface of the liquid crystal display is surrounded by a ring-shaped display partition member from the front of the display surface. By providing such a ring-shaped display partition member, it is possible to make it stand up from the liquid crystal display so as to be visually recognized, and it is possible to realize a sharp display by improving the three-dimensionality (for example, Patent Document 3).
JP-A-62-58112 Japanese Patent Laid-Open No. 11-248490 Japanese Patent Laying-Open No. 2005-241626 ([0068] to [0102], FIGS. 12 to 23)

  By the way, the applicant provides a vehicle display device having a ring display partition member, and further provides a plurality of LED light emitting portions at predetermined intervals around the ring of the ring display partition member, and sequentially emits these LED light emitting portions. In addition, the ring-shaped display partition member itself does not rotate but has a rotation mode in which the ring-shaped display partition member is visually recognized as if it is rotating, and the image displayed on the display surface of the liquid crystal display is rotated to be visually recognized. Furthermore, Japanese Patent Application No. 2004-318862 has proposed a display device for a vehicle that has a sharp display.

  Such a vehicle display device requires wiring for passing current to a plurality of LEDs. For this purpose, a storage groove is formed on the back surface of the ring-shaped display partition member, and a wiring board, for example, FPC (flexible wiring) is formed therein. Substrate) must be accommodated, it is necessary to form a ring-shaped display partition member with a ring width commensurate with it. In addition, since it is necessary to fix the FPC and the holding member with a fixing member such as a screw in order to prevent floating or warpage of the accommodated FPC, the space for arranging the fixing member is a ring-shaped display partition member. Must be secured within.

  Here, if an arrangement space for both the FPC and the fixing member is to be secured, the ring width becomes wide, the display area of the liquid crystal display hidden by the ring-shaped display partition member increases, and the visibility deteriorates or the appearance is improved. If the FPC is divided at the place where the fixing member is arranged, it is not preferable because the wiring from the divided FPC to the outside of the ring-shaped display partition member becomes complicated.

  Therefore, it is necessary to wire the FPCs together without being divided at the location where the fixing means is arranged, and to prevent the ring width from increasing in the space necessary for the arrangement of the fixing means.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to enable an annular member surrounding a partial region on the display surface to move along the display surface in front of the display surface of the display.

For example, although not shown in FIG. 1, in a normal mode such as when the ring member 2 is moved, the light emitting unit located at a position corresponding to the numerical scales “0” to “6” instructing 0 to 6000 rotations of the tachometer is white. The light emitting part located at the position corresponding to the numerical scales “7” and “8” instructing 7000 to 8000 rotations indicating the red zone displayed near the lower right of the circular dial plate emits red light. The light emitting unit at the position without the numerical scale is turned off.

  On the other hand, in the rotation mode, the circular dial of the tachometer displayed on the display surface of the LCD 3 is rotated, and the numerical scale “7” indicating the 7000-8000 rotation indicating the red zone normally displayed near the lower right of the circular dial. ”And“ 8 ”are moved to the upper part of the circular dial, and the light-emitting portions 2A to 2L are sequentially turned on and off in accordance with the rotation of the circular dial, and finally the normal mode is reached at the end of the rotation of the circular dial. Turn on white or red in the same positional relationship as the hour. Thereby, although the ring member 2 itself does not rotate, it can be visually recognized as if the ring member 2 is rotating. Note that the rotation mode is described in Japanese Patent Application No. 2004-318862, and is not a point of the present invention, so a more detailed description is omitted.

  Next, the configuration of the ring member 2 will be described with reference to FIGS. As shown in FIGS. 2 and 3, the ring member 2 includes a ring 21, a light guide member 22, an FPC 23, an FPC pressing member 24, and attachment members 25 and 26, and these components are assembled.
