[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a head-up display in which a display pattern for an automobile display device, particularly a display device installed on the ceiling of a passenger compartment is reflected by a reflecting mirror and projected on a windshield. And the like.

[0002]

2. Description of the Related Art As a head-up display device of this kind in an automobile, Japanese Patent Application Laid-Open No. 63-11447 discloses a display 22 provided on a ceiling 21 in a passenger compartment 20 as shown in FIG. There is disclosed an invention in which a display pattern of No. 22 is reflected by a reflecting mirror 23 arranged near a dashboard, and a driver 24 visually recognizes the reflected display pattern.

[0003]

[Problem to be solved by the present invention]
In the invention of JP-A-3-11447, the display 22
Is disclosed as adopting a liquid crystal display, a fluorescent display, a CRT, or the like. However, even when any of the displays 22 is employed, the reflective display pattern can be used even in the nighttime even if the reflective display pattern is adopted. Requires a light source to make it visible. Usually, a green halogen light is used as the light source in many cases. However, the halogen light may be visible from the outside of the passenger compartment 20. In this case, especially in the case of a commercial vehicle, the halogen light is disposed outside the roof. Hood indicator (speed light)
There is a concern that it may be mistaken.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and an apparatus for preventing light from a light source of a display from being seen from outside a vehicle compartment. The purpose is to provide
An opening is formed in the roof header mounted below the ceiling of the passenger compartment, and an indicator provided with a light source is provided in the space above the roof header, behind the opening in the vehicle longitudinal direction. A first reflector is disposed in front of the display, and a display pattern of the display is reflected from the first reflector in a direction of a second reflector mounted near the instrument panel. (2) When the light source is configured to project onto a windshield via a reflecting mirror, the light source is positioned at the front end of the vehicle at a position where the incident position of light from the windshield is highest in the vertical direction of the vehicle and the opening. The display device is provided below a line connecting the rear ends of the sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes a passenger compartment, and a roof header 3 is provided horizontally below a ceiling 2 thereof. When the vehicle is mounted, the space 4 is formed above the driver's head. At the same time, an opening 5 is formed in the roof header 3 to communicate the cabin 1 with the space 4.

Reference numeral 6 denotes a light source, such as a halogen lamp, provided in the space portion 4. A display plate 7 for displaying various information patterns such as a liquid crystal display is provided on the front surface of the light source. The provided display is installed behind the opening 5 formed in the roof header 3 in the vehicle front-rear direction. Reference numeral 8 denotes a first reflecting mirror mounted in front of the opening 5 for reflecting a display pattern displayed on the display panel 7 with the first reflecting mirror 8. Through the part 5, the vehicle interior 1 is reached.

Reference numeral 9 denotes a second reflector, which is mounted on the instrument panel 10. The reflective display pattern is further reflected by the second reflector 9, and this is reflected on the combiner 12 mounted on the windshield 11. Project and make it visible to the driver. In the figure, 13 is the windshield 11
Is a finisher for attaching to the vehicle body 14.

[0008] At the front end A of the vehicle, the position where the incident position of the light from the windshield 11 is highest is the lower end of the finisher 13 and the rear end 5 of the opening 5.
However, since the light source 6 and the display panel 7 are installed below the line L, the light of the light source 6 cannot be directly seen from outside the passenger compartment 1.

In the structure shown in FIG. 2, the light source 6 and the display panel 7 are installed below a line L connecting the lower end of the finisher 13 and the rear end 5a of the opening 5 due to the structure of the cabin 1. This is another embodiment in which the shielding plate 15 is provided on the lower surface of the front end 5b of the opening 5 of the roof header 3.
Is provided vertically.

The height H of the shield plate 1.5 is determined by the line L2 connecting the upper end 16 of the front surface of the light source 6 and the display panel 7 to the rear end 5a of the opening 5, and the front end of the opening 5. The distance D from the portion 5b to the intersection K with the lowered perpendicular S was set to be equal to or longer than (H
> D). Thereby, the light of the light source 6 can be made invisible directly from outside the cabin 1.

[0011]

As described above, the display device for an automobile according to the present invention forms an opening in a roof header mounted below the ceiling of the vehicle compartment, and the above-mentioned device is provided in the space above the roof header. A display provided with a light source is provided behind the opening in the vehicle front-rear direction, and a first reflector is provided in front of the display, and a display pattern of the display is installed from the first reflector. The light source is reflected in the direction of a second reflector mounted near the instrument panel, and is further projected on a windshield via the second reflector. The light source of the display is not directly visible from outside the vehicle compartment because the light source from the windshield is located below the line connecting the rear end of the opening with the site where the incident position of the light from the windshield is highest. . Therefore, there is an effect that the safety of a driver or a pedestrian of an oncoming vehicle or the like can be ensured without being mistaken for light of a hood indicator (speed light) or the like disposed outside the roof.
