Problems solved by technology

[0005] That is, in the above-mentioned conventional vehicle display device, the eye position (eye point) moves up and down due to the difference in the body shape and sitting posture of the user such as the driver. The raised portion of the instrument cover makes the display incomplete for users such as the driver
[0006] In addition, in the case of ordinary vehicles (cars), the distance between the user's eye position and the display is about 900mm to 1000mm, which is a long distance. The displayed characters and graphics need to be larger than a certain size. If such a size is to be displayed, it will not only inevitably increase the size of the display and increase the manufacturing cost, but also block the front view of the vehicle. Therefore, the technology of increasing text and graphics cannot be used

Embodiment 1

[0046] First, according to Figure 1 ~ Figure 3 The configuration of the vehicle display device of the first embodiment will be described.

[0047] The display device for a vehicle according to the first embodiment includes: a display 3, which is located at a position lower than the lower part of the front windshield 1, and arranged on the vehicle front side of the instrument panel 2; and a magnifying lens 4, which is vertically arranged on the instrument panel 2. rear side of the vehicle.

[0048] In further detail, the display 3 is composed of, for example, a liquid crystal display, and the display 3 displays the vehicle information according to the driving signal generated by the display driving unit 6 corresponding to the vehicle information signal output from the vehicle information calculation unit 5 respectively arranged in the instrument panel 2. displayed on the display screen of monitor 3.

[0049] The vehicle information calculation unit 5 is connected to various ...

Embodiment 2

[0068] Next, a vehicle display device according to Embodiment 2 of the present invention will be described.

[0069] In the vehicle display device of the second embodiment, the same structure as the first embodiment is used, but it is different from the first embodiment in that the display content of the display 3 is magnified mainly by the outer edge portion 4a of the magnifying lens 4. . Other structures are the same as those of Embodiment 1.

[0070] Here, the magnifying lens 4 consists of Figure 8 In the shown circular convex lens 4', a part of the outer edge side part 4a of the central part shown by the dotted circle (in the embodiment, a rectangular part shown by the solid line) is formed.

[0071] If the height when disposing display 3 is not high enough, display 3 cannot be seen through magnifying lens 4, therefore, display 3 is too conspicuous.

[0072] However, in Embodiment 2, the display content on the display 3 is magnified mainly by using the outer edge side ...

Embodiment 3

[0076] Next, a vehicle display device according to Embodiment 3 of the present invention will be described.

[0077] The vehicle display device of the third embodiment has the same structure as the second embodiment, but differs from the second embodiment in that the upper end side of the magnifying lens 4 is inclined toward the vehicle front side with respect to the instrument panel 2 . Other structures are the same as those of Embodiment 2.

[0078] Figure 9 (In this figure, the reflected line of sight is indicated by a dashed-dotted line) shows a case where the magnifying lens 4 is tilted with respect to the instrument panel 2 so that the magnifying lens 4 faces the driver's eyes. In this case, the magnifying lens 4 not only transmits the display content on the display 3, but also reflects the driver's own face and the clothes worn by the driver due to the reflection of the driver's side surface of the magnifying lens 4. The lens 4 overlaps the displayed image, making it...

Abstract

The display apparatus for vehicles is provided with: a display unit (3) disposed on an upper part of an instrument panel (2) located under a front glass (1) within the vehicle compartment; an enlarging lens (4) extending vertically from the upper part of the instrument panel (2) and disposed closer to the rear of the vehicle than the display unit (3) such that a display on the display unit (3) can be shown as enlarged to the driver; and an opaque light blocking wall (7) extending from outer edge portions of the display unit (3) to at least near left and right positions (M, N) where first lines (LL1, LR1) connecting the left and right eyes of the driver with the outer edge portions on the corresponding sides of the enlarging lens (4) intersect a second line (L2) extending from the display unit (3) in the vehicle width direction.

Description

technical field [0001] The present invention relates to a display device for a vehicle capable of displaying vehicle information and the like to be conveyed to a user such as a driver with good visibility. Background technique [0002] As a conventional display device for a vehicle, there is known a device in which light from the front of the vehicle does not pass through the lower side light-shielding shielding portion (Japanese: light-shielding mask portion) formed around the windshield of the vehicle. The area between the front parts of the instrument panel forms a backlit light-shielding area, and is equipped with a light-emitting display for displaying vehicle information at a position that can be seen by the driver in the light-shielding area, and makes the lower side The light shielding portion functions as a shade (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-280247 [0004] However, the above-mentioned co...
