[Three-dimensional meter display action]
In the vehicle display device 1 according to the embodiment, as shown in FIG. 5, the vehicle speed meter 11 and the engine tachometer 12 are displayed as images on the LCD 3c.
Further, on the LCD 3b, a fuel gauge 21, a water temperature gauge 23, various display lights and a warning light 22 are displayed as images at positions that do not overlap the vehicle speed meter 11 and the engine tachometer 12 of the LCD 3c.
Next, on the LCD 3c, the vehicle speed digital display 31 and the agent 32 are displayed as images at positions that do not overlap the vehicle speed meter 11, the engine tachometer 12, the fuel gauge 21, the water temperature gauge 23, the various indicator lights and the warning light 22. .

Then, the vehicle speed digital display 31 and the agent 32 displayed on the innermost LCD 3a are reflected by the full mirror 6 and transmitted to the half mirrors 5a and 5b, and are shown to the driver, so that the display image 30 is the deepest. It will appear to be located on the side.
Next, the fuel gauge 21, the water temperature gauge 23, various display lamps and the warning lamp 22 displayed on the LCD 3 b are reflected by the half mirror 5 b and transmitted through the half mirror 5 a to show the driver, thereby displaying a display image. 20, it appears to be located in front of the display image 30 and at a position behind the half mirror 5b.
Next, the vehicle speed meter 11 and the engine tachometer 12 displayed on the LCD 3c are reflected by the half mirror 5a and shown to the driver so that the display image 10 is in front of the display image 20 and behind the half mirror 5a. Will appear to be located.
Therefore, since the driver sees the display images 10, 20, and 30 displayed at different depth positions at the same time, a stereoscopic display with a depth can be seen.

[Action to move the display up and down]
The person who drives the vehicle has various heights, sitting heights, and the like, and the height of the eye point varies from person to person. Moreover, in order to show a meter panel to a driver | operator, it has the subject peculiar to a meter panel of showing through the space of steering. Therefore, regarding the display on the meter panel, being able to adjust up and down is important for providing an easy-to-read display.

However, in the vehicle display device 1 of the present embodiment, in order to perform the display three-dimensionally, the color, the size, the display content, the display shape, etc. are easily applied and displayed on the conventional meter. In order to display not only things but also more information in an easy-to-view manner for the driver, the display image on the LCD 3 is reflected and displayed as a virtual image.
For this reason, the LCD 3 has half mirrors 5a and 5b and a full mirror 6 above (or below) the LCD 3.

In the vehicular display device that performs such three-dimensional display, when the display is to be moved up and down, the half mirrors 5a and 5b, the full mirror 6, the LCD 3, the backlight 4 and the like are moved up and down as a whole. In order to move a large thing up and down, the force which the mechanism requires becomes large, and the mechanism and a drive part become large. Therefore, the driving unit also requires a large driving force commensurate with it, the power consumption of the driving unit increases, a large space between the mechanism and the driving unit is required, and the cost of the mechanism and the driving unit increases.
In the instrument panel where the instrument panel is installed, there is no room for installation. If a large amount of space is required inside the instrument panel to install the meter panel, the instrument panel will rise, and the driver's external field of view will be narrowed. This is undesirable because it affects driving.

In addition, the drive unit requires a large driving force and the current consumption increases. In recent years, the types and number of in-vehicle devices that use a power source are increasing in vehicles, and the increase in power consumption of in-vehicle devices has increased. The high output of the alternator is required, which may even affect the engine performance, that is, the vehicle performance, and it is very important to suppress the increase in power consumption.
Furthermore, in a vehicle, unless the three-dimensional display as in the present embodiment is also realized by suppressing the cost, its spread and development cannot be expected and it will not lead to the next technological development, so the cost can also be suppressed. It is very important.
In the vehicle display device 1 of the present embodiment, these problems are sufficiently satisfied.

In the vehicle display device 1 of the present embodiment, in order to move the display up and down so that the display is most easily seen by the driver, the driver inputs an operation through the operation unit 9. This operation input is transmitted to the motor unit 232 of the drive unit 23 via the vehicle device 7.
In the motor unit 232, the motor is driven according to the moving direction and moving amount of the operation input, and the pinion gear 231 is rotated by the driving force.
When the pinion gear 231 rotates, the rack gear 221 engaged with the pinion gear 231 performs linear motion.
In this way, when the rack gear 221 moves linearly, the longitudinal direction thereof becomes the front-rear direction that is the back side and the front side, so the moving unit 22 provided with the rack gear 221 moves in the front-rear direction.

When the moving unit 22 moves, since the half mirrors 5a and 5b and the full mirror 6 are fixed, the display surfaces 3a, 3b, and 3c that perform display on the reflecting member move.
Thereby, first, when the LCD 3 moves to the near side, the display surfaces 3a, 3b, 3c move to the near side.
Then, since the half mirrors 5a and 5b and the full mirror 6 are inclined so that the upper end is positioned on the near side with respect to the lower end, the display images 10a, 20a and 30a on the display surfaces 3a, 3b and 3c of the LCD 3 are The half mirrors 5a and 5b and the full mirror 6 are reflected at the upper end side. Therefore, the display images 10, 20, and 30 shown to the driver by reflection move upward as shown in FIG.

When the movement of the moving unit 22 by the motor unit 232 moves the LCD 3 to the back side, the display surfaces 3a, 3b, and 3c move to the back side.
Then, the display images 10a, 20a, and 30a on the display surfaces 3a, 3b, and 3c of the LCD 3 are reflected on the lower ends of the half mirrors 5a and 5b and the full mirror 6, respectively. Therefore, the display images 10, 20, and 30 shown to the driver by reflection move downward as shown in FIG. 4 (b).

  Thus, in the vehicle display device 1 of the present embodiment, the display is moved up and down by moving only the moving unit 22 provided with the LCD 3 and the backlight 4. Therefore, the drive unit and the drive mechanism do not take up a large space, and the force required to slide the LCD 3 can be very small. Therefore, the current consumption can be suppressed, and the cost can be reduced with a simple configuration.

[Action to transmit information in extra space]
Further, in the vehicle display device of this embodiment, the size of the margin that can be displayed on the ends of the display surfaces 3a, 3b, and 3c of the LCD 3 caused by the vertical movement is determined, and a large margin is allowed. Display information on the side where it occurs.
This information does not necessarily have to be communicated to the driver every short time, but it should be displayed even if it is only occasionally visible.
As a result, the vehicle display can be more conveniently used.

Next, the effect will be described.
In the vehicle display device of the embodiment, the effects listed below can be obtained.

  (1) The display surface portion is provided on the display surface portions 3a, 3b, 3c side of the LCD 3 stored in the storage portion formed on the vehicle body side with the display surface portion facing either one of the vertical directions.

In the vehicle display device 1 to be performed, the half mirrors 5a, 5b and the full mirror 6 are provided so as to be fixed to the hood portion 21 inside the instrument panel 2, so that vehicle information is reflected toward the front side, and the LCD 3 is an instrument. The moving unit 22 is slidable with respect to the driving unit 23 so as to be arranged in a flat plate shape in the panel 2 and to move the LCD 3 to the front side or the back side. Accordingly, since the moving part 22 is moved back and forth by the engagement of the rack gear 221 and the pinion gear 231, the moving part 22 is moved back and forth by the engagement of the pinion gear 22 and the pinion gear that drive the LCD 3 with a motor. Then, the vertical position of the display image generated by reflection by the half mirrors 5a and 5b and the full mirror 6 is changed. This makes it possible to change the vertical movement position of the image while suppressing costs.

  (2) In accordance with the vertical movement of the display image by the moving means, the vehicle device 7 determines a displayable portion that occurs above and below the display image, and displays information on the displayable portion determined by the determination means. As a result, a more convenient display can be achieved.
