Description

[Detailed Description of the Invention] [Industrial field of application] The present invention uses a reflecting member to reflect the display pattern of the display to the driver's seat side, and displays the operation information of the display on the instrument panel position of the dashboard. The present invention relates to a display device for a vehicle which is adapted to display.

[Problems to be solved by conventional techniques and devices]

As an example of the vehicular display device using the reflection member as described above, the one shown in FIG. 6 is considered.

In the apparatus shown in the figure, the column housing 20 is formed by forming a display housing 20a on the column cover 20 that covers the steering shaft.
0 and a display device 50 for displaying various driving information on the windshield 10 side of the display device housing portion 20a, and a reflecting member 30 having a reflecting surface facing the driver's seat is provided on the dashboard 40. The above-mentioned indicator 5 by 30
The display pattern of 0 is reflected to the driver seat side so that the driving information can be visually recognized from the vicinity of the viewpoint 60 on the driver seat side.

As a result, the conventional meter hood can be omitted, and a large space can be secured in the dashboard by only having the reflecting member on the dashboard.

However, the reflection member 30 is intended to reflect the display pattern, and the display mode visually recognized on the reflection surface is the display itself of the display device 50, which is a monotonous display.

An object of the present invention is to improve a reflective member in a vehicular display device in which driving information of a display device is visually recognized using a reflective member, to enhance a display effect and to provide interesting display. To do.

[Means and Actions for Solving the Problems]

The vehicular display device of the present invention made to achieve the above object reflects the driving information of the display on the display surface of the light guide plate and guides a predetermined pattern such as a gauge pattern for reading the driving information. A groove is carved on the back surface of the light plate, light from a light source provided on the side surface of the light guide plate is diffused in the groove portion, and a predetermined pattern by the groove portion is light-emitted and displayed on the display surface of the reflecting surface on which operation information is displayed. I did it.

〔Example〕

FIG. 1 is a perspective view showing a vehicle display device according to an embodiment of the present invention,
FIG. 2 is a sectional view thereof, in which 1 is a windshield of the vehicle, 2 is a dashboard, and 3 is a steering wheel.

The dashboard 2 projects from the lower edge of the windshield 1 toward the interior of the vehicle, and the instrument panel position is cut out to form a step portion 21. The reflecting member 4 is disposed on the step portion 21 via the support 5, and the reflecting surface 4a of the reflecting member 4 is provided at the instrument panel position of the dashboard 2 toward the driver's seat side. ing.

The reflecting member 4 has a substantially rectangular shape with the long side in the left-right direction,
The reflecting surface is a concave surface that is slightly curved in the left-right direction, and is supported by the support 5 while being slightly inclined downward.

Reference numeral 6 denotes a column cover that covers a steering shaft rod (not shown) that connects the steering wheel 3 and the steering mechanism in the engine room. ,
A portion opposite to the end portion on the steering wheel side is inserted into the dashboard 2.

The uppermost end of the column cover 6 on the steering wheel side has substantially the same height as the surface of the stepped portion 21 of the dashboard 2, and the column cover 6 is maintained at this height.
The upper surface of the column cover 6 is projected upward from the end portion on the steering wheel side to the middle portion, and both side surfaces of the column cover 6 are projected left and right in the middle portion to form the indicator housing portion 61.

In the display housing 61, an engine speed indicator 7 _{1 for} displaying the engine speed in a bar, a water temperature indicator 7 _{2 for} displaying a water temperature in a bar, and a fuel level indicator 7 _{3 for} displaying a fuel remaining amount in a bar. Are the display surfaces of the reflecting surface 4a of the reflecting member 4, respectively.
It is stored facing the.

The column cover 6 itself is located near the dashboard 2 of the column cover 6 by the column cover 6 itself.
Is formed, and two rows of window holes and a recess having a V-shaped cross section are formed on the upper surface thereof. indicator 7 ₅ for displaying the display 7 ₄ and the vehicle speed to perform a warning display is housed in the display surface to the reflective member 4 side. As the display accommodated in the display accommodating portions 61 and 62, a self-luminous type using a fluorescent display tube, a light emitting diode, a transmissive liquid crystal having a backlight, or the like is applied.

By the arrangement of the display 7 _{1-7 5} described above, the display that can be viewed from the vicinity of the driver's viewpoint 8 in the range of the reflective surface 4a of the reflective member 4 is shown in FIG. 3 . In the figure, A, B, and C are engine speeds, temperatures, and fuel residual amounts displayed by bars, D is a warning display, and E is a vehicle speed display.

FIG. 4 is a view showing a cross section of the reflecting member 4,
Is formed by the surface of a light guide plate 41 made of a translucent material such as acrylic resin, and a light source 42 such as a white lamp is covered by a frame 43 on the upper side surface of the light guide plate 41. It is installed.

On the back surface of the light guide plate 41, that is, the surface opposite to the reflection surface 4a, a groove portion 41a is engraved so as to draw a gauge pattern indicating the engine speed.

Then, when the light source 42 attached to the side surface of the light guide plate 41 is turned on, the light from the light source 42 is guided inside the light guide plate 41 and is diffusely reflected by the side surface of the groove portion 41a, whereby the groove portion 41a emits light. and, the gauge pattern F of light emitted groove portion 41a are displayed so as to overlap with the bar display a according to the engine speed indicator ₇₁ as for example shown in Figure 5.

As a result, the bar display and the gauge pattern have a relatively deep display, and the display can be interesting.

[Effect of device]

As described above, according to the vehicle display device of the present invention,
In a vehicular display device in which driving information of a display device is visually recognized using a reflection member, a groove is formed on the back surface of the light guide plate to draw a predetermined pattern and a light source is provided on the side surface of the light guide plate. Light is diffused in the groove to cause the groove to emit light, and the predetermined pattern of light emission and the driving information reflected by the reflecting member are overlapped so that they can be visually recognized. Therefore, a display effect is enhanced and an interesting display is provided. It can be carried out.
