Description

  The present invention relates to a vehicle display device that is mounted on a vehicle and capable of displaying various information.

  In recent years, display devices for vehicles are not limited to navigation devices, but are very widely used for televisions, game machines and the like, and are frequently used even during non-driving. Moreover, it is desired that the display screen unit can be changed to a position suitable for the purpose of use of the vehicle display device.

  It is desirable that the position of the display screen part during driving is set at a position that is close to the line of sight during driving and does not block the driver's line of sight. On the other hand, when it is used for amusements such as televisions and game machines when not driving, it is desirable to have a good display position for each seat in the vehicle, and when a display screen part is not required It is desirable to be stored in the dashboard.

  Conventionally, a vehicular display device including a display screen unit housed in a dashboard and a reflection mirror that reflects the display surface of the display screen unit in the direction of the driver is provided by changing the angle of the reflection mirror. In some cases, the amount of information can be slightly adjusted by using the difference in display area shown in (see, for example, Patent Document 1).

  However, the vehicle display device disclosed in Patent Document 1 is mainly intended for a display screen unit as a means for providing information to a driver, and is information that considers the visibility of the display screen unit for passengers. It is unlikely that it was intended as a means of providing. This can be seen from the fact that, for example, the reflecting mirror is arranged to face the driver on the dashboard.

Japanese Patent Laid-Open No. 11-165562

  Since the conventional vehicular display device is configured as described above, the driver and passengers need information in the vehicle, and the display screen position that the driver and passengers expect in the running state. However, it is difficult to change the position of the display screen part greatly, for example, satisfying the information display when the passenger uses a television or a game machine when the vehicle is stopped. There was a problem that it was difficult.

  The present invention has been made to solve the above-described problems, and can display information appropriately for the driver and passengers by greatly displacing the position of the display screen unit, and the dashboard. An object of the present invention is to obtain a display device for a vehicle that can be stored up to the same surface as the upper surface of the vehicle.

  The vehicle display device according to the present invention includes a height adjustment function unit capable of adjusting the height position of the display screen unit to a height position separated from the dashboard surface by a predetermined distance, and the height adjustment function unit according to the height adjustment position. And an inclination angle adjustment function part for adjusting the inclination angle of the display screen part.

  According to the present invention, the display screen unit can be displaced to a height position that is easy to see for both the driver and the passenger, and the inclination angle of the display screen unit can be adjusted according to the height adjustment position. Therefore, the driver and the passenger can see the display screen in an optimal state. And since a display screen part can be stored below the same surface as the upper surface of a dashboard if needed, it does not become a hindrance to a driver's visual field at the time of a driving. In addition, there is an effect that the appearance of the passenger compartment is not impaired.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same members and the same functions are denoted by the same reference numerals.
Embodiment 1 FIG.
In FIG. 1, a steering wheel 1, a speedometer 2, a tachometer 3, a fuel indicator 4, and the like are disposed in front of the driver's seat, and a recess 6 is formed in a dashboard 5 on the left front side of the steering wheel 1. In addition, a display 7 serving as a display screen unit is accommodated in the recess 6.
In FIG. 2, which shows an enlarged cross section of the recess 6 in FIG. 1, the display 7 is wide enough to show all the functions of the car navigation system, and is tilted so that the screen faces upward. Are installed.

FIGS. 1 and 2 show a state in which the uppermost portion of the display 7 is displaced to the same level or lower as the upper surface of the dashboard 5, but the display screen of the display 7 obstructs the driver's view in such a state. The display can be used at a height close to the driver's line of sight.

  In addition, if it is difficult to see, it is possible to adjust the tilt angle of the display 7 so that it is easy to see. In other words, the display screen can be visually recognized without forming a projection portion by the display 7 on the dashboard 5, and the driver can also adjust the angle so that the driver can easily see, while ensuring a very good field of view. The vehicle display device can be used comfortably.

  In FIG. 3, a base 9 having the same size as that of the base 8 is fixed to the bottom of the recess 6 so as to face the base 8. A long groove 12 is formed on the left side surface of the base 8 and the base 9 in the front-rear direction. Shafts 14 are slidably fitted in these long grooves 12 so as to be slidable. The shafts 14 are fixed to the ends of the two links 10 and 11 which are crossed in an X shape and are pivotally attached to the crossing portions. Although not shown, the right side has the same structure. With the configuration of the parallel motion mechanism, the pedestal 8 obtains a height adjustment function unit that can be displaced in the vertical direction while maintaining a state parallel to the base 9.

  Here, if an arbitrary one shaft 14 is fixed to a long rack in the front-rear direction on this shaft 14 and the pinion meshed with this rack is driven forward / reversely by a height adjustment motor (not shown), the height adjustment motor By driving, the display 7 can be moved and adjusted together with the base 8 in the vertical direction.

  By driving the height adjusting motor, it is possible to displace the base 8 at a low position as shown in FIG. 5A and the base 8 at a high position as shown in FIG. 5B. The maximum displacement in the height direction of the pedestal 8 can be arbitrarily set by increasing the distance between the shafts 14 and 14 opposed on the link or by increasing the length of the long groove 12.

  As shown in FIGS. 6 and 7, the display 7 can be raised at a steep angle by the display tilt angle adjustment function unit, and the display 7 can be moved upward by the height adjustment function unit. Use the display 7 on the dashboard in the same way as when stowed in the dashboard, by projecting the display screen stored in the dashboard onto the dashboard and raising the tilted display screen at a steep angle close to the vertical. Is possible. Thereby, the same form as the conventional on-dash type car navigation system is possible, and amusement such as navigation, television, and game machine can be shared with the passengers.

  In particular, as shown in FIG. 8, in the configuration in which the display is provided by forming the recess 6 in the dashboard corresponding to the middle between the driver seat 15 and the passenger seat 16, the display screen 7 c can be viewed well from the rear seat 17. Is possible. Furthermore, as shown in FIG. 9, it protrudes from the surface of the dashboard 5 to a predetermined distance (for example, a height position that matches the position of the eyes so that the display screen 7c can be seen well from both the driver's seat and the rear seat). Can be used with displacement. When the car is stopped, a person in the back seat can play a game by watching the display screen of the display 7 or watch a television program in an extremely easy-to-view state.

  In the present embodiment, the rotation support mechanism for supporting the holes 7a and 7b for achieving the tilt angle adjusting function portion of the display by the shaft 8a, the links 10 and 11 for achieving the height adjusting function portion, the long groove 12 and the like are included. Each of the parallel motion mechanisms has an independent configuration, does not have an interlocking relationship, and the display 7 can independently adjust its inclination angle and height regardless of the inside or outside of the dashboard, and Since these can be used in combination, the optimum display screen position can always be ensured by adjusting according to individual differences and usage of the driver.
