[Detailed description of the invention]

[0001]

This invention relates to a vehicle head-up display (hereinafter abbreviated as HUD) comprising a driving information display in a dashboard of a vehicle such as an automobile and a combiner on a windshield for displaying an image displayed by the display. Do).

[0002]

2. Description of the Related Art An HUD is intended to display driving information such as a vehicle speed in front of a windshield of a vehicle to improve the driver's visibility of the driving information. In order to improve the visibility, it is necessary to display driving information as far away as possible. As a means for achieving this distant display, there is a case where the distance (optical path) from the display element (for example, liquid crystal) of the operation information display to the combiner of the windshield is increased.

[0003]

However, various components have recently been installed in the dashboard of a vehicle, and there is almost no space in the dashboard for securing the above optical path. .

Conventionally, as shown in FIG. 3, the meter assembly 1 accommodating the display section 8 and the optical path component 7 of the optical path from the meter assembly 1 to the combiner deposited on the windshield are separate bodies. 2 and optical path component 7
The head-up display consisting of a large size was difficult to accommodate in a dashboard.

The present invention provides a vehicle head-up display which is small in size, easily accommodated in a dashboard, and which can secure an optical path of a sufficient length in the dashboard so that clear driving information can be visually recognized. As an issue. As prior art data of the present application, there is Japanese Utility Model Laid-Open No. 2-10130.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to an inner wall for dividing a space inside a dashboard into two in a direction in which a meter assembly is buried, and an inner wall for dividing the space into two. The display section of the meter assembly disposed in the occupant-side space of the divided space, and the other space in the space divided by the inner wall, which corresponds to the driving information. An operation information display that generates a light beam, and a reflector disposed in the space on the other side and reflecting a light beam from the operation information display device to a combiner deposited on a windshield, the operation information display device comprising: The gist of the invention is a head-up display for a vehicle, wherein an optical path of the light beam from the container to the reflection plate is arranged in the space on the other side along the vehicle width direction.

[0007]

According to the present invention constructed as described above, the light beam corresponding to the driving information generated by the driving information display in the space on the other side is applied to the space on the other side along the vehicle width direction. The light passes through the provided optical path, is reflected by the reflector disposed in the space on the other side, and is subsequently reflected by the combiner deposited on the windshield to enter the driver's eyes. The dashboard is generally long in the vehicle width direction, and the space on the other side is also long in the vehicle width direction. Further, the space on the other side is separated from the space in which the display unit is provided with an inner wall interposed therebetween, and a display unit and the like are not provided in the space on the other side. Therefore, a long optical path can be easily secured in the dashboard without increasing the size of the device.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. Meter assembly 1 is accommodated in a dashboard 101 in the case 5 and co-general instruments of the vehicle. Reference numeral 2 denotes a display of operation information, for example, speed, arranged in the meter assembly 1.
The back cover 1b is a front cover of the case 5. 5a is a back cover of the case 5. Reflector plates 31 and 32 are arranged in the meter assembly 1, and a reflector plate 33 is arranged in the case 9 . 4 is a reflective film (combiner) deposited on the windshield 6. A indicates an optical path of light emitted from the display device 2, and E indicates a driver's eye. The reflection plate 3
1, 32 and 33 are displayed on the reflector 3. Also, FIG.
Reference numeral 8 denotes a display unit as in the conventional example shown in FIG.
b corresponds to the inner wall. Therefore, the back cover 1b in FIG.
Right side (in Fig. 1, the direction of embedding of the meter assembly 1 is left
The space 103 (to the right) is the space on the occupant side from the back cover 1b.
The space on the left side, that is, the space inside the case 5 is on the other side
And display 2 corresponds to the operation information display
I do.

In the above configuration, the light exiting the display 2 travels in the meter assembly 1 in the vehicle width direction along the optical path A, is reflected by the reflectors 31 and 32 and enters the case 9 , and is reflected by the reflector 33. After being reflected and leaving the case 9 , it is reflected by the combiner 4 and enters the driver's eye E.
As a result, the driver can visually recognize one piece of driving information, for example, speed, with his head raised, that is, while looking directly ahead. In the present embodiment, the width of the vehicle is
The light traveling along the optical path A provided by the
Of the three reflectors 31, 32, 33
It is configured by a combination.

As shown in this embodiment, the case 5 is integrated with the meter assembly 1 to form an optical path component .
Since the optical path A is arranged in the vehicle width direction, the head-up display of the present embodiment is smaller and simpler than the conventional head-up display, and a long optical path can be secured, so that visibility to driving information is improved. Improve.

[0011]

[Effect] In this invention, the space inside the dashboard is divided into two by the inner wall as described above, and an optical path is arranged along the width direction of the vehicle in the space on the back side (the space on the other side). ing. For this reason, the vehicle head-up display of the present invention can be easily housed in the dashboard, and
Since a sufficiently long optical path can be ensured, it has the effect of improving the driver's visibility of driving information.
