Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a display device for a vehicle.

(Prior art) Recently, due to the spread of highways nationwide, vehicle driving information (speed, engine revolutions,
In particular, there is growing interest in design in improving the visibility of warning alarms, etc.).

Conventional display devices for vehicles have adopted a configuration in which the actual pointer and scale (real image) provided in a part of the meter cluster are simply visible through a flat lens (Fresnel lens) that also functions as a hood. There were many. That is, in this configuration, the position of the display source is always fixed regardless of the actual traveling speed of the vehicle.

However, as the speed of the vehicle increases, the driver's field of view becomes narrower and tends to be fixed at an apogee in front of the viewpoint. For this reason, the conventional display structure described above has the disadvantage that it becomes extremely difficult to see.

Therefore, recently, as a countermeasure, for example,
A head-up display device as described in Japanese Patent No. 4437 has been proposed. The device is
For example, a projection device that generates a predetermined information image is provided in a space inside the dash board, and a combiner that forms the information image from the projection device in front of the windshield is provided, and the information image on the display source side is converted into a virtual image. The image is always focused in front of the windshield. In the case of such a configuration, as long as the driver always looks ahead through the windshield, he or she can simultaneously view the driving information of the vehicle, which is safe and easy to read.

Moreover, the configuration of the prior art includes a projection device moving means for shifting the rearward position of the projection device, and the projection device moving means is operated depending on, for example, the distance between the vehicle and the vehicle running in front. As a result, the front-rear position of the information image in front of the windshield is changed. Therefore, according to this configuration, if the vehicle speed data is input manually instead of the inter-vehicle distance data, it is also possible to control the change of the information image position according to the vehicle speed.

(Problem to be solved by the invention) However, as mentioned above, the projection device itself, which is the information display source, is used in a narrow place inside the dash board where various ducts and wiring are laid out, which is inherently a space factor constraint. In practice, moving it is extremely difficult and difficult to achieve.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above problems, and is an information display that displays predetermined information on an information display surface formed in the front part of a vehicle interior. In the vehicle, a recess is formed in the information display surface, and the information display source is installed in the recess, and first and second An illumination means is provided, and each of the first and second illumination means is appropriately selected to illuminate the information display source, thereby projecting the information display source at apparently different positions in the front-rear direction of the information display surface. It is characterized by the following.

(Function) In the configuration of the vehicle display device of the present invention, first, a recess is formed in the display surface on which information is to be displayed, and an information display source such as the above-mentioned meter is installed in the recess. First and second illumination means are provided below and above the information display surface in which the recessed portion is formed, and shadows are created by appropriately selecting each of the first and second illumination means to illuminate the information display source. By turning the position upside down, the information display source can be projected at a position different from the appearance in the front-rear direction of the information display surface.

Therefore, the real image of the display source can be displayed with the perspective changed in the longitudinal direction of the vehicle without particularly moving the display source itself.

(Effects of the Invention) As a result, according to the vehicle display device of the present invention, it is possible to realize the perspective display function of the display source according to the vehicle speed etc. with an extremely simple configuration without any restrictions on the number of vehicles space factor. becomes possible.

(Example) FIGS. 1 to 5 show a vehicle display device according to an example of the present invention.

First, FIG. 5 shows the system configuration of the entire vehicle constituting the display device, and reference numeral 1 in the figure indicates the compartment of the vehicle.

The vehicle interior portion l is partitioned on its upper side by a roof 3 supported by at least four front and rear pillars 2a to 2d, and is partitioned on four sides by front and rear windshields and windshields 48 to 4d on both left and right sides. is surrounded by.

An instrument panel section 6 located on the front side of the vehicle interior section 1 includes a meter cluster part 7 for displaying various vehicle driving information such as a speedometer and a tachometer toward the driver's seat side. is provided.

As shown in FIGS. 1 and 2, for example, the meter cluster part 7 includes a meter unit 11 having a plurality of display sources 11a and 11c of an image display type embedded in the dash board part, and the meter unit. 11, a first illumination lamp 13 provided above the information display surface 12, a second illumination lamp 14 provided below the information display surface 12, and It is composed of a meter lens 10 having a hood function, which is located in front of the information display screen section 12, and a cluster hood section 15 that covers the meter lens 10.

In the above configuration, the display surface section 12 includes the plurality of display sources 11 as shown in FIGS. 2 to 4, for example.
A plurality of recesses 16a to 16c are formed corresponding to a to Ilc, and the information display sources 11a to lie are installed at the bottoms of the respective circuit parts 16a to 16c, as shown in FIG.

Then, each information display source 11a in such an installed state is 1
1c, the first illumination lamp 13 illuminates the recesses 16a at an angle as shown in FIG.
A shaded portion B is formed above 16c. As a result,
The real images of the information display sources +1a to llc that are visually recognized by the driver's eyes through the meter lens 10 are perceived as images receding toward the back, and are essentially the information display sources 1
The same effect as moving 1a-lie to the rear of the vehicle can be obtained.

On the other hand, if we turn off the first illumination lamp 13 and turn on only the second illumination lamp 14 to provide illumination as shown in FIG. A shadow area B similar to -L is formed on the lower side. As a result, the information display sources 11a to 11ie within the recess 16a=I6c appear to protrude to the front. Therefore, it is possible to obtain substantially the same effect as when the information display sources IIa to Ilc are moved to the front of the vehicle (reversal characteristic of unevenness due to change in shadow position).

Further, when both the first and second illumination lamps 13 and 14 are turned on, the shadow portions T3 + and B are not formed on either the upper or lower sides of the recesses 16a to 16c. Therefore, the real image positions of the information display sources +1a to +1c described in - can be viewed as they are.

This also applies when all of the above-mentioned illumination lamps +3.14 are turned off during the day.

Therefore, in this configuration, each of the illumination lamps 13.14
By controlling the lighting state (ON, 01"F) or illuminance according to the vehicle speed, it becomes possible to provide an easily visible driving information display device extremely simply and at low cost.

In addition, when displaying distance according to the vehicle speed as described above, if the vehicle speed is high, it will naturally be displayed on the far side, but when it is displayed on the far side, for example, If the distance between the vehicle and the vehicle in progress is rapidly decreasing, the display source can be quickly moved in one direction toward the driver in front, increasing the ability to voluntarily alert the driver to prevent a rear-end collision. This is effective.
