It is an object of the present invention to provide an automobile display device that can be made as large as possible. [Structure] A display pattern of a display plate 8 is reflected by reflecting mirrors 15 and 16 by a light source 7 in a roof header 3 mounted below a ceiling 2 of a passenger compartment 1, and this is reflected by a windshield 19.
The roof display 3 has a movable shield plate 12 slidably provided to the roof header 3 for blocking passage of the light from the light source 7 into the vehicle compartment 1. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a head-up display device for an automobile, in which a display pattern of a display unit installed on the ceiling of a vehicle compartment is reflected by a reflecting mirror and projected on the windshield. The present invention relates to a display device for an automobile.

[0002]

[Prior art]

 As a head-up display device of this type in an automobile, as shown in FIG. 5, a roof header 2 having an opening 3 is provided in the vicinity of the ceiling of a vehicle compartment 1, and inside the roof header 2 there is a rear portion of the opening 3. A light source 5 equipped with a display 4 on the front side, a first reflecting mirror 6 arranged in front of the opening 3, and a reflection display pattern from the first reflecting mirror 6 mounted on an instrument panel 7. There is a structure in which the light is projected on the combiner 10 of the windshield 9 through the two-reflecting mirror 8 so that the driver P can visually recognize the reflective display pattern. Further, the roof header 2 is in the vicinity of the light source 5 or the like. In addition, as shown in FIG. 6, a spotlight device 11 that illuminates the driver P's hand is often installed.

[0003]

[Problems to be solved by the device]

 However, in the prior art shown in FIGS. 5 and 6, since the light source 5 having the display 4 and the like and the spotlight device 11 are arranged in the roof header 2, two light sources are used. There is a problem in that it needs to be installed, and the space in the roof header 2 as a store, which is the original purpose of use, is significantly reduced.

[0004]

[Means for solving problems]

 The present invention has been made to solve the above-mentioned conventional problems, and a single light source is used both for projecting a display pattern of a display device and for illuminating a spotlight device. The purpose is to reduce the number of parts and to provide the roof header with the largest possible storage space, and the main point is to provide a roof mounted below the vehicle cabin ceiling. If the light source in the header reflects the display pattern of the display board by a reflecting mirror and projects it on the windshield, the roof header also has a movable shield that blocks the light of the light source from passing into the vehicle interior. In a display device for an automobile, the plate is provided slidably.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is an explanatory sectional view showing the structure of an automobile display device according to the present invention, FIG. 2 is an enlarged sectional view of the main constituent parts of FIG. 1, and FIG. 3 is a perspective view of the main constituent parts of FIG. FIG. 4 is a perspective view of the main constituent part at the time of another operation.

In the figure, reference numeral 1 denotes a passenger compartment such as a driver's seat, in which a roof header 3 is horizontally mounted below a ceiling 2 thereof to form a space portion 4 above the driver P as a storeroom. At the same time, an opening 5 is formed in the roof header 3 to establish communication between the vehicle compartment 1 and the space 4.

Reference numeral 6 denotes a concave reflecting mirror installed in the space 4, which is mounted behind the opening 5 of the roof header 3, and the front opening of the concave reflecting mirror 6 is fixed toward the front of the vehicle. Has been done. A light source 7 such as a halogen lamp is fixed to the mirror core of the concave reflecting mirror 6, and a display plate 8 for displaying various information patterns such as liquid crystal is provided at the front opening. is set up.

Reference numeral 9 denotes a circular hole formed below the outer peripheral wall 6 A of the concave reflecting mirror 6, which is opened at a position corresponding to the light source 7 so as to allow the light of the light source 7 to pass therethrough. The focusing cylinder 10 is connected to the. Reference numeral 11 denotes a pair of guide rails that are spaced apart from each other in a direction orthogonal to the optical axis of the light source 7, and are provided on the roof header 3 corresponding to the focusing tube 10 of the concave reflecting mirror 6. A movable shield plate 12 is slidably installed at 11. A movable focusing tube 13 for fixing the vehicle interior 1 and the space 4 to each other is fixed to the movable blocking plate 12 at a position corresponding to the focusing tube 10. A condenser lens 14 is mounted in the cylinder 13.

Reference numeral 15 denotes a first reflecting mirror mounted in front of the opening 5, for reflecting a display pattern displayed on the display plate 8. This reflective display pattern covers the opening 5. Pass through to the passenger compartment 1. In the figure, 16 is a second reflecting mirror mounted on the instrument panel 17, and 18 is a combiner mounted on the windshield 19.

Therefore, as shown in FIG. 3, when the movable shield plate 12 is slid along the guide rail 11 in the arrow direction to close the focusing tube 10 of the concave reflecting mirror 6 with the movable shield plate 12, The light from the light source 7 projects the display pattern of the display plate 8 onto the first reflecting mirror 15. Then, this display pattern is reflected by the first reflecting mirror 15, is reflected again by the second reflecting mirror 16, is projected on the combiner 18 mounted on the windshield 19, and is visible to the driver P.

Next, when illuminating the driver P's hand, as shown in FIG. 4, the movable shield plate 12 is reversely slid in the direction of the arrow so that the movable focusing plate 10 of the concave reflecting mirror 6 moves. When the tubes 13 are aligned with each other, the light from the light source 7 passes through both the focusing tubes 10 and 13 and is collected by the condenser lens 14, so that the driver P's hand can be illuminated. The movable focusing tube 13 may have a swinging rotation structure so that the movable focusing tube 13 can irradiate an arbitrary direction.

[0012]

[Effect of device]

 As described above, the vehicle display device according to the present invention reflects the display pattern of the display plate by the reflecting mirror by the light source in the roof header mounted below the vehicle compartment ceiling and projects it on the windshield. According to this structure, the roof header is slidably provided with the movable shield plate for blocking the light of the light source from passing through the interior of the vehicle, so that the display pattern of the display plate can be projected by one light source. Since it can be used as both a light source and a spotlight, the number of parts can be reduced, and a wide space inside the roof header can be secured.
