Abstract

PURPOSE:To decrease the rise height size of a top cover and to arrange the cover top closely to a windshield by holding the top cover at a rising attitude while part of it enters a chassis when the top cover is opened. CONSTITUTION:The area of the opening part A of the chassis 11 is sufficiently large and the cover top 12 is large enough to cover the opening part A. While the cover 12 is raised, the cover top 12 and a display member 13 are minimized in projection height size. Further, a display member 13 which is raised together with the cover top 12 is close to the windshield 2 behind the wide opening part A, so the display surface 13a of the display member 13 becomes easy to see through the opening part A from the assistant driver's seat and driver's seat. While the display member 13 is raised, the display surface 18a turns slightly clockwise from the vertical attitude and the tip of the display member 13 slants slightly into the vehicle room. Therefore, the display surface 13a is prevented from becoming hard to see owing to external light. Consequently, the display member can be arranged closely to the windshield.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a display device installed in a vehicle interior to display various information such as road information, and particularly to a display device installed above an instrument panel. This invention relates to an in-vehicle display device that does not obstruct the driver's field of view and can be installed in a position that is easy to see. [Prior Art] Recently, devices have been considered that display various information such as road information by installing a display member such as a liquid crystal display inside the cabin of an automobile. In this case, it is assumed that a display member such as a display is usually arranged at a relatively low position, such as on the front of an instrument panel. However, this low position makes it difficult to see from the passenger and driver seats, making it impractical. [Problems to be Solved by the Invention] Therefore, the display member is placed on the top of the instrument panel and in front of the windshield so that it can be most easily seen from inside the vehicle! It is possible to do so. However, in this case, if the display device is raised high, it will obstruct the driver's field of view. Furthermore, if the stand-up height is reduced, the display device such as the display must be made smaller, making it difficult to see the displayed information. In addition, it is easier to see the display member when it is located as close to the windshield as possible, but if the display member is placed in this position and the height is lowered, the device itself will be placed further back when viewed from the passenger seat, and various operations will be performed. It becomes difficult to remove. The present invention solves the above-mentioned conventional problems. For example, when installed on the top surface of an instrument panel inside a vehicle, the height of the display device can be lowered, and the display device such as a disk display can be sufficiently mounted. The object of the present invention is to provide an in-vehicle display device that can be made large in size, have an operating section close to the driver's seat or passenger seat, and have a display member located close to the windshield. [Means for Solving the Problems] An in-vehicle display device according to the present invention has an opening formed on the top surface of a chassis installed in a vehicle interior, a cover top covering the opening, and a cover top installed inside the cover top. The cover top is supported so as to rotate from a position covering the opening to a position where a portion of the cover top enters the chassis and stands up, and the display member also rotates relative to the chassis. The rotation support portion of the display member is disposed at a position closer to the cover top in the standing position than the rotation support portion of the cover top, and the cover top and the display member are coupled so as to be relatively movable. It is made up of [Operation] With the above method, when the cover top is closed, the cover top becomes flush with the instrument panel, etc. If you raise the cover top from this position, the cover top will stand up with its base tucked into the chassis, and its height will be lower. The movement of the cover top follows the display member, such as a display, when the display member is rotated by a motor or the like. The display member is positioned in front of the cover top with the cover top standing up. In other words, the display member stands up with a rotation locus with a smaller radius than the cover top, and when the cover top rises, it is placed almost on the entire surface of the cover top. Additionally, since the power top has a large turning radius, it can be built over a relatively large area, and when installed on the instrument panel, it can be raised from a position close to the driver's or passenger's seat. Furthermore, when the vehicle is standing up, the display device can be placed closer to the windshield. [Example 1] Hereinafter, an example of the present invention will be explained with reference to the drawings. Figure 1 shows an in-vehicle display device according to the present invention installed on an instrument panel inside a vehicle! FIG. 2 is a vertical sectional view showing the in-vehicle display device. In Figure 1, numeral 1 is the instrument panel inside the vehicle, and 2 is the windshield. Reference numeral 10 is a display device for driving a vehicle according to the present invention. The chassis 11 of this in-vehicle display device 10 is embedded in the upper surface of the instrument panel 1, and the upper side 11a of the chassis 1l almost coincides with the upper surface 1a of the instrument panel 1.
lb almost coincides with the front surface 1b of the instrument panel l. The chassis 11 has an opening A extending from its top surface to the front. Reference numeral 12 is a cover top that covers the opening A, and 13 is a display member equipped with a liquid crystal display. The front surface of this display member l3 is the display surface 13a.
It becomes. Support arms 12a are integrally formed on both sides of the force part top l2. As shown in FIG. 2, the base end 12b of the support arm 12a is rotatably supported by a support shaft 14 provided on the chassis l1. Therefore, the cover lug 12 rotates around this support shaft 14 (the rotation locus is indicated by α). This rotation trajectory α
In this case, the position shown by the solid line in FIG. 2 is a state in which the cover tab 12 completely covers the opening A.
Further, the posture shown by the chain line in FIG. 2 is a state in which the cover top l2 stands up with respect to the chassis 11. Since the cover top 12 rotates around the support shaft l4 located deep within the chassis 11, when the cover top l2 stands up in the chain line state, most of the rear part of the cover top 12 is inside the chassis 11. The height H of the cover top l2 from the upper side 11a of the chassis 11 is very small. Moreover, the cover top 12 has a wide area so that it can almost completely cover the opening A which is long open in the front and rear.

On the other hand, both sides of the display member 13 are rotatably supported with respect to the chassis 11 by support shafts 16. This support shaft 16 is located on the left side of the support shaft l4 of the cover tab l2 in the drawing. That is, the support shaft 16 of the display member 12 is located closer to the cover top l2 in the open state than the support shaft 14 of the cover top 12. The rotation locus of this display member 12 is indicated by β.
This rotation locus β is different from the rotation locus α of the cover top 12. As shown in FIG. 2, a guide groove 12c is formed on the inner surface of the cover tab 12, and a bottle-shaped protrusion 13b provided at the rear upper end of the display member 12 fits into the guide groove 12c.
It is slidably inserted inside. The cover tab 12 and the display member 13 are connected to each other by the guide groove 12c and the projection 13b. As mentioned above, since the rotation trajectory α of the cover top l2 and the rotation trajectory β of the display member 13 are different, the cover top l2 and the display member 13 move between the solid line state and the chain line state in FIG. At this time, the projection 13b slides on the guide groove 12c, and the cover top 12 and the display member 13 move relative to each other. As shown in FIG. 2, when the cover l2 covers the opening A, the display member l3 is housed in a position shifted rearward (in the direction of the windshield 2) with respect to the cover l2, and the cover l3 is 12 stands up from the chassis l1 as shown by the chain line, the display member 13 assumes a standing position with its upper end at approximately the same height H as the cover top l2. As mentioned above, this height dimension H is the minimum, and the height dimension H is the minimum, and the height dimension H is the minimum, and the height dimension
The amount of protrusion from the upper surface 1a is the minimum.

As shown in FIG. 1, mechanisms such as a motor M and a reduction gear are arranged in the chassis 11, and the display member 13 is powered between the posture shown by the solid line and the posture shown by the chain line in FIG. It is designed to be driven. The cover tab 12 is configured to rotate following the rotational movement of the display member 13. Furthermore, internal mechanisms such as the motor M shown in Figure 1 are hidden by a suitable cover. Incidentally, both the cover top l2 and the display member 13 may be rotationally driven by the motor M. In this case, since the rotation angle of the cover top 12 and the rotation angle of the display member l3 are different, the difference in drive angle between the two is adjusted by the gear ratio or the like. Alternatively, the cover top 12 may be driven by a motor, and the display member l3 may follow this movement.
Thus, in the above structure, the area of the opening A of the chassis 11 is sufficiently large, and the cover top 12 has a size that can cover this wide opening A. Moreover, when the cover top 12 is in an upright state, the protruding height dimension H of the cover top l2 and the display member 13 can be minimized. Moreover, the display member 13 that rises together with the force top 12 is located on the windshield 2 at the rear of the wide opening A.
Since the display member 1 is located close to the
The display surface 13a of No. 3 can be easily seen from the passenger seat or driver's seat.
In the illustrated embodiment, when the display member 13 is in an upright position, its display surface 13a is rotated slightly clockwise rather than vertically, that is, the tip of the display member 13 is directed toward the interior of the vehicle. It is in a slightly slumped position. This prevents the display surface 13a from becoming difficult to see due to external light. As shown in FIGS. 1 and 2, this in-vehicle display device is provided with a keyboard 2l. Both sides of this keyboard 21 are supported by rotating arms 22.
Further, the rotating arm 22 is rotatably supported by a support shaft 23 provided on the inner surface of both side walls of the chassis 11. As a result, the keyboard 2l and the rotating arm 22 can be housed in the chassis 11, as shown by solid lines in FIG. In this stored state, the display member 13 in the stored state is stacked above the keyboard 21. In addition, the keyboard 21 and the rotating arm 2
2 is rotated to the outside of the chassis 11, it assumes the posture shown in FIG.

In addition, a push lock switch 3 is located at the bottom of the chassis 11.
0 is provided, and its pressing portion 31 protrudes into the chassis 11. When the keyboard 21 is retracted, the pressing portion 3l is pressed by the keyboard 21 and is in a locked state. With the display member 13 standing up and the cover tab 12 open, the keyboard 2l
When you press with your finger, the suppression part 3 of the push lock switch 30
1 is pressed, and the suppressing portion 31 is projected by the spring. As a result, the keyboard 2l is lifted to a position where it can be grasped with fingers. Further, when the pressing part 31 is protruding, the push lock switch 30 is turned OFF, and at this time, the motor M is not driven, and the display member l
3 and cover top l2 are prevented from being closed. [Effects] As described above, according to the present invention, when the cover top is opened, a part of the cover top enters into the chassis and assumes the standing position, so the rising height of the cover top in the open state is low. Become. In addition, the rotation support part of the display member is located closer to the open cover top than the rotation support part of the cover top, so even if the cover top is large, the display member can be placed at almost the same height as the cover top in the open state. It can be done. In addition, the power top can be made large, and while the opening is wide, the raised display member can be positioned behind the opening, and the display member can be placed close to the windshield as in the example shown in the figure. You will be able to stand up. Furthermore, since the cover top can be made larger and the opening can be made wider, it becomes easier to see the display member located at the rear.
