DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device (display image) provided at a substantially intermediate position between a driver's seat and a passenger's seat of an instrument panel in a vehicle cabin. The present invention relates to a display device for a vehicle, which is provided so that a driver can see it by reflecting the light on a provided reflecting plate.

[0002]

2. Description of the Related Art A vehicle is installed at a substantially intermediate position between a driver's seat and a passenger's seat inside an instrument panel provided in a vehicle cabin, and transmits information necessary for driving the vehicle to an eye point direction of the driver. As a conventional example of a vehicular display device (head-up display device) capable of performing reflection display, there is a structure disclosed in Japanese Patent Application Laid-Open No. 62-101535, for example.

FIGS. 3 and 4 show the structure of this conventional example.
The display device 2 is provided at an intermediate portion in the vehicle width direction on an instrument panel 1 provided in a vehicle interior, that is, at a substantially intermediate position between a driver's seat and a passenger seat. The structure of the display device 2 is such that a support 3 provided inside the instrument panel 1 has C as shown in FIG.
A display 4 composed of an RT or the like is mounted with its display surface 5 facing upward. In addition, a display opening 6 corresponding to the display surface 5 of the display 4 is formed on the upper surface of the instrument panel 1.

[0004] Reference numeral 7 denotes a lid which can open and close the display opening 6. The lid 7 is rotatably supported via a support shaft 8, and an inner surface of the lid 7. Is provided with a reflecting surface (mirror) 9 for reflecting and displaying the image displayed by the display 4 in the direction of the viewer.

When the display image on the display 4 is viewed, the lid 7 is raised obliquely upward and the display 4 is activated, so that the light-emitting display image on the display 4 is
It is configured to be reflected and displayed in the direction of the viewer via a reflection surface (mirror) 9 provided on the inner surface of the lid 7.

[0006]

However, in such a conventional display device, the display device 4 is provided at the center of the vehicle body in the width direction, that is, at a substantially intermediate position between the driver's seat and the passenger's seat. The display surface 5 of the display 4 is positioned substantially in the horizontal direction, and the front cover attached to the front side of the display surface 5 is also horizontally attached. Here, “horizontal” means that the driver is straight. Therefore, the driver's viewing angle with respect to the display surface 5 and the passenger's viewing angle with respect to the display surface 5 are substantially the same. In other words, as shown in FIG. 5, the position of the driver's eye point 6 and the position of the passenger's seat eye point 12 are substantially symmetrical with respect to the indicator 4, so that the driver can reflect the reflection surface 9. When the display information is viewed, the face of the person located in the passenger seat is reflected on the front cover surface, and the face reflected on the front cover is reflected on the reflection surface 9 and reflected. When there is no passenger, the light incident from the upper part of the window on the passenger side is reflected toward the driver by the surface of the front cover 10 and the reflection surface 9. There was a problem that the display information was difficult to see.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem. In a vehicle display device for displaying a display image displayed by a display device using a reflector (mirror) as a virtual image, the present invention is directed to a passenger seat direction. The purpose of the present invention is to increase the visibility of display information on the display by tilting the display surface of the display so that incident light from the display is not reflected on the display surface of the display in the direction of the driver's eye point. .

[0008]

According to a first aspect of the present invention, a display image (information) displayed on a display provided in an instrument panel for a vehicle is provided.
In a vehicular display device, in which the reflecting plate is tilted on the instrument panel and reflects the light toward a viewer, the display surface of the indicator is tilted in a forward direction of the vehicle body with respect to a horizontal plane of the vehicle body. The display device is characterized by being a vehicle display device inclined by θ.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIG. 1 and FIG. 2, reference numeral 11 denotes an instrument panel mounted in a vehicle cabin. A display opening 12 is provided on the upper surface of the instrument panel 11 and at the center in the vehicle width direction. A lid 13 is attached to the display opening 12 so as to be openable and closable. The lid 13 includes a lid 13A and the lid 13A.
The support portion 13B is integral with the instrument panel 11B.
Is fixed via a mounting screw 15 to a bracket 14 located inside the bracket 14.

The bracket 14 is long in the vehicle width direction.
At both ends, respective side walls 14A bent in an L shape are integrally formed, and a guide pin 16 is provided at a front portion of the side walls 14A, and a guide pin 16 is provided at a rear portion of the side walls 14A. Is supported by a nut bracket 18 via a support shaft 17. A movable nut 19 is non-rotatably held at the center of the nut bracket 18 in the vehicle width direction. A screw rod (screw rod) 20 is engaged with the movable nut 19.

Both ends of the screw rod 20 are rotatably supported by a display bracket 21 fixed to the back side of the instrument panel 11, and a power transmission provided on the screw rod 20. Gear 2
2 is meshed with a drive motor 24 via a reduction gear group 23. The pair of guide pins 16 on the left and right sides are guided along a substantially U-shaped cam groove 26 provided on the left and right side walls 25 provided integrally with the display bracket. .

Reference numeral 27 denotes a display attached to the display bracket 21. The display 27 is a self-luminous display such as a liquid crystal display or a CRT. Reference numeral 27A denotes a display surface of the display. The mounting position of the display 27 is set such that the display surface 27A is inclined at an angle θ of about 15 degrees forward of the vehicle body with respect to the horizontal plane (L). Reference numeral 28 denotes a reflector (mirror) attached to the inside of the lid 13, and when the lid 13 is fully opened, a display image displayed by the display 27 is transmitted through the transmissive reflector 28. Is displayed on the driver's eye point 29 as a virtual image.

The operation of the present embodiment has been described above. Next, when the operation of the switch (not shown) causes the drive motor 24 to rotate in the reverse direction, for example,
4 is transmitted to the screw rod 20 via the reduction gear group 23.
And the screw rod 20 rotates in the reverse direction. In FIG. 1, the movable nut 19 starts moving in the X direction along the screw rod 20 due to the reverse rotation of the screw rod 20.

By the movement of the movable nut 19, the nut bracket 18 integral with the movable nut 19 and the bracket 14 connected to the nut bracket 18 via the support shaft 17 are also pulled in the X direction. Thus, when the bracket 14 is pulled in the X direction, the guide pin 16 protruding from the bracket 14 moves in a shape of a letter “C” along the cam groove 26. The body 13 moves in the Y direction to close the display opening 12 provided in the instrument panel 11.

When the guide pin 16 passes through a substantially intermediate point of the concave cam groove 26, the cover 13 moves in a direction substantially parallel to the X direction. The display opening 12 provided in the instrument panel 11 is completely closed by the lid 13, being drawn substantially in front of the vehicle body substantially parallel to the rim.

When the drive motor 24 is rotated forward when the display opening 12 is completely closed by the lid 13, the screw rod 20 rotates forward, contrary to the above operation. In the direction of the axis of the screw rod 20. By the movement of the movable nut 19, the guide pin 16 protruding from the bracket 14 descends along the cam groove 26, and as a result, the lid 13 gradually rises, and finally, as shown in FIG. The lid 13
Is stopped and held at a standing position inclined at approximately 45 degrees.

When the display 27 is illuminated and displayed when the reflector 28 stands up at an inclination of approximately 45 degrees, the luminescent display image is reflected by the reflector 28 and reflected by the reflector 28. The displayed image can be visually confirmed at the driver's eye point 29 as a virtual image in front of the reflector 28.

However, the display surface 27A of the display 27
Is inclined at an angle θ of about 15 degrees to the lower front side of the vehicle body with respect to the horizontal plane L of the vehicle body. Therefore, the direction of reflection of the display image on the reflector 28 by the display 27 is reflected downward from the height position of the eye point 29 (the upper end of the display image is slightly tilted toward the driver).

Accordingly, the form of the virtual image viewed by the eye point 29 is slightly flat and distorted, but the external light reflection angle on the display surface 27A by the display 27 is also on the lower side. As shown by 2, external light from the passenger's head and the upper part of the passenger side window can be prevented from being reflected in the direction of the driver's eye point, thereby increasing the visibility of the virtual image displayed on the display. It is something that can be done.

[0021]

As described above, according to the vehicular display device of the present invention, the vehicular display device that reflects the display image displayed on the display device provided inside the instrument panel by the reflection plate. The display surface 27A of the display device is tilted with respect to the horizontal plane of the vehicle body at an inclination angle θ that is inclined forward of the vehicle body. External light or the like from above is not reflected in the direction of the driver's eye point, and the visibility of the display image on the display is improved.
