Description

  The present invention relates to a vehicle display device that is installed in a driver's seat of a vehicle and displays various types of information to an occupant, and is suitable for use in an automobile or the like.

  In recent years, for example, in a display device for a vehicle mounted on an automobile, the number of information displayed therein is increasing. On the other hand, on the dashboard portion where the vehicle display device is installed, devices other than the vehicle display device, such as a vehicle interior air conditioner and an airbag, are mounted, and the types of these devices and devices tend to increase. For this reason, there is a strong demand for miniaturization of the vehicular display device.

  That is, in the vehicle display device, it is necessary to satisfy both conflicting demands for realizing miniaturization while increasing the number and types of information to be displayed.

  As a display device for satisfying such a requirement, for example, a pointer instrument is provided, a display member for displaying predetermined information is provided on the viewer side of the pointer instrument, and at least a part of the pointer of the pointer instrument is a display member. Some are configured to be exposed to the surroundings (see Patent Document 1).

In this case, the display space of the display device for vehicles is effectively used by providing a display member for displaying predetermined information on the inner side of the rotation range of the pointer of the pointer instrument that has not been used conventionally.
Japanese Patent Laid-Open No. 15-294499

  In the above-described conventional display device, the display member is arranged on the front side of the pointer instrument. In other words, both are arranged so as to overlap in the viewing direction. Therefore, in order to ensure good visibility of the pointer instrument on the lower side in the visual recognition direction, that is, in order to make the pointer clearly visible, the space that can be occupied by the display member arranged above the pointer instrument is naturally limited. It will be

  By the way, as a display member, for example, a liquid crystal display is used. In general, in a liquid crystal display, a connector unit for inputting an electric signal for driving liquid crystal to the outside of a display screen for actually displaying information is used. There are incidental facilities. Therefore, in the case of a liquid crystal display of a size that can be placed in a limited space in front of the above-mentioned pointer, the size of the display screen is reduced, so that the driver can hardly see the display content and the display member has good visibility. There was a problem that it was difficult to ensure.

  On the other hand, it is possible to use a liquid crystal display with a larger display screen by devising the shape of the electrical connector portion or the like, but there is a problem that the cost of the liquid crystal display increases.

  The present invention has been made in view of the above-described problems, and provides a vehicle display device that is excellent in visibility and has a novel appearance while suppressing an increase in cost by using a small display member having excellent mountability. For the purpose.

  In order to achieve the above object, the present invention employs the following technical means.

  The display device for a vehicle according to claim 1 of the present invention includes a display device for displaying predetermined information and an edge plate having an opening disposed on the front side of the display device. A display device for a vehicle that visually recognizes a display device through an opening, wherein an optical magnifying means is disposed on the opposite side of the edge plate from the display, and the outer periphery of the optical magnifying device is more than the outline of the opening. The configuration is on the outside.

  Here, as the optical enlarging means, for example, a convex lens or a Fresnel lens can be used.

  When an occupant such as a driver sees the vehicle display device, the display device is visually recognized as a virtual image larger than the display device on the other side of the optical magnifying means, for example, the convex lens. Moreover, since the outer periphery of the optical enlarging means is outside the contour line of the opening, almost the entire display is visually recognized as an enlarged virtual image. Therefore, the visibility of the display device can be improved.

Accordingly, a vehicle display device having excellent visibility and a novel appearance can be provided while suppressing an increase in cost using a small display device having excellent mountability. The display device is configured such that the outline of the opening is visually recognized through an optical enlarging means.

  In this case, since the outline of the opening defines the outer shape of the display, it is part of the design of the display.

  Therefore, it is possible to provide a display device for a vehicle that has excellent visibility and a novel appearance by making the appearance of the display device complete by visually recognizing the contour line of the display device and the opening as an enlarged virtual image.

  According to a third aspect of the present invention, there is provided a display device for a vehicle comprising a pointer instrument disposed behind the indicator, wherein the pointer instrument has a display design such as scales, numerals, characters, etc. It is set as the structure visually recognized outside.

  In order to achieve downsizing of the display device for vehicles, from the viewpoint of information display, when a display device, for example, a liquid crystal display device is disposed above the center portion of the pointer instrument which is a dead space, the mountable liquid crystal display device is small. Therefore, the visibility of the liquid crystal display may be reduced.

  On the other hand, if it is set as the structure of the display apparatus for vehicles of Claim 3 of this invention, visibility will be improved by making a virtual image visible while using the small display member excellent in mounting property and low cost. Can be improved.

  Therefore, it is possible to provide a vehicular display device that has excellent visibility and a novel appearance while suppressing an increase in cost.

  The vehicle display device according to claim 4 of the present invention is configured such that the display is a liquid crystal display.

  The liquid crystal display device has a wide selection of display designs displayed on the screen, and can display a plurality of information simultaneously or sequentially.

  Accordingly, it is possible to provide a vehicular display device that is excellent in visibility and has a novel appearance while effectively utilizing the display space.

  In the vehicle display device according to claim 5 of the present invention, the opening shape of the edge plate is formed in a circular shape, and the display design of the pointer instrument is arranged on an arc.

  Thus, by unifying the display design by using the display design of the pointer instrument and the external shape of the display as similar shapes, it is possible to provide a vehicular display device with excellent design and a novel appearance.

  In this case, as in the vehicle display device according to claim 6 of the present invention, if the outer shape of the edge plate is formed in a circular shape, the uniformity of the display design of the pointer instrument and the display design of the display device is further strengthened. Therefore, it is possible to provide a vehicular display device that is further excellent in design and has a novel appearance.
