Description

DETAILED DESCRIPTION OF THE INVENTION “Industrial field of application” The present invention relates to a display device such as an on-vehicle television set installed in a vehicle such as a passenger car.

“Conventional technology and its problems” It is widely used to install audio equipment such as tape decks and compact disc pewers, that is, car stereos in vehicles, but in recent years, there has been a demand for installing a TV in vehicles, especially in passenger cars. Therefore, small televisions for cars, so-called car televisions, are gradually becoming popular.

By the way, when a car TV is installed in a vehicle, there is a concern that the driver may be distracted by the TV and neglect to drive if it is in a position seen by the driver. For this reason, it has been traditionally said that it is desirable to install the car TV in a position where it can be seen only from the rear seats and passenger seats, and not from the driver's seat. There was the inconvenience that the driver had to purposely move to another seat in order to watch TV during a medium or long stop.

Also, it is considered to install a car TV on the dashboard of the vehicle, but the conventional car TV is a cathode ray tube type, so even though it is small, it is not easy to install on the dashboard, and it is temporarily installed. Even if it is possible, in that case, the dashboard is almost occupied by the car TV, and it becomes impossible to secure the installation space for other devices such as audio devices, which is not realistic.

The present invention has been made in view of the above circumstances.Although the driver cannot see it while driving, the driver can also see it from the driver's seat while parked or stopped,
Moreover, it is an object of the present invention to provide an in-vehicle display device that can be installed in a dashboard of a vehicle while leaving an installation space for other devices.

"Means for Solving the Problem" The in-vehicle display device of the present invention includes a thin display main body such as an LCD TV, a casing that stores the display main body in a substantially horizontal state, and a casing inside the casing. A feed mechanism that is provided to move the display body in and out of the casing, and supports the display body so as to be vertically rotatable from a horizontal state when the display body is moving outside the casing. A support mechanism that supports the display body so as to be rotatable in the left-right direction, and a detection unit that detects a traveling state of a vehicle in which the display body is installed,
Drive means for driving the support mechanism based on the detection result of the detection means to rotate the display body in the left-right direction.

[Operation] The in-vehicle display device of the present invention is built in a vehicle dashboard or the like, and is stored inside the casing with the display body kept substantially horizontal when not in use. After the display body is sent out from the casing by the feed mechanism, the display body is vertically rotated by the support mechanism so as to stand up, and the screen is directed forward.

In addition, the in-vehicle display device of the present invention allows the display body to be oriented in any direction by freely rotating the display body in the left-right direction by the support mechanism when the vehicle is in a stopped state. As can be seen in the above, when the detection means detects that the vehicle is in a running state, the drive means forcibly drives the support mechanism to rotate the display main body in the left-right direction, and the direction from the driver's seat. Changed to make it invisible.

This mounting member 27 rotates together with the rotary table 35 as shown in FIG. 6 when the rotary table 35 of the stand 5 rotates, so that the TV main body 1 connected to the mounting member 27 via the holding member 29. The direction can be changed to the left and right.

Next, as shown in FIG. 4 (b), the holding member 29 includes a rear plate 29a fixed to the rear surface of the TV main body 1 and a top plate 29b fixed to the rear upper surface of the TV main body 1. And has hinge portions 29c, 29c formed at both ends of the rear plate 29a by being bent backward. The hinge portions 29c, 29c are formed with holes 55, 55 for connecting the holding member 29 to the mounting member 27 by pins 28, 28 so as to be rotatable in the vertical direction. Pins 56, 56 projecting inward are fixed to the rear side of 55, 55.

These pins 56, 56 are located inside the notches 52, 52 formed in the side walls 27b, 27b of the mounting member 27 when the holding member 29 is connected to the mounting member 27, and the notches 52, 52. It is provided as a stopper that engages with 52 to restrict the vertical movement of the holding member 29 with respect to the mounting member 27. That is, as shown in FIG. 7A, the holding member 29
With the TV main body 1 to which is attached being almost horizontal, the pin 56 abuts on the upper portion of the notch 52 to prevent further downward rotation, and as shown in FIG. The pin 56 contacts the front portion of the notch 52 in a state where the television main body 1 is slightly upward from the vertical direction, and further upward rotation is restricted.

The leaf spring 30 is attached to the central position of the rear plate 29a of the holding member 29. This leaf spring 30 is a rear plate 29a.
It is attached so as to extend rearward from the front end, and its tip is bent inward, and projections 57, 57 are formed therein. When the holding member 29 is rotated in the up-and-down direction, the tip of the leaf spring 30 is shown in FIG.
As shown in (b), it moves along the upper portions of the stoppers 53, 53 provided on the rear wall 27c of the mounting member 27,
As a result, the protrusions 57, 57 and the recesses 54 of the stoppers 53, 53 are sequentially engaged with each other to provide a click feeling, and the holding member 29, that is, the television main body 1 is locked at an arbitrary angle. ing.

In the vehicle-mounted television having the above-mentioned configuration, a thin liquid crystal display is used as the television body 1, and the television body 1 is stored in the casing 2 in a horizontal state. The size of the audio device can be about the same as that of the audio device for use, and therefore can be installed on the dashboard D leaving an installation space for other audio devices and the like. When not in use, the TV main body 1 is stored in the casing 2, that is, in the dashboard D, so that there is no hindrance and the TV main body 1 remains in the dashboard D even when it is in use.
Since it is located in front of, it does not interfere with the view and does not obstruct the view.

In addition, in this vehicle-mounted television, the direction of the television main body 1 can be freely changed by rotating the rotary table 35 of the stand 5 when the vehicle is in a stopped state (that is, while the vehicle is parked or stopped). Both sides can be viewed from the driver's seat or the passenger's seat without any hindrance, and when the vehicle is in a running state, the turntable 35
Is forcibly rotated by the motor 36 (driving means), so that the TV main body 1 faces the passenger seat side,
This prevents the driver from seeing the vehicle, and thus effectively prevents neglected driving.

If the direction of the TV body 1 is forcibly changed when the vehicle shifts from the stopped state to the running state, the direction of the TV body 1 is changed to the original state when the vehicle is stopped again. If it is automatically returned to, it is not necessary to reset the orientation of the television body 1 every time the vehicle is repeatedly run and stopped. Further, since the vehicle is always in the stopped state when the engine of the vehicle is stopped, it is not necessary to detect the traveling state by the detection means 6 when the engine is stopped. It should be possible to adjust it freely.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and the television main body 1 may be used during traveling.
Various modifications are conceivable as long as it is configured to forcibly change its direction so that it cannot be seen from the driver's seat.

For example, although the vehicle-mounted television of the above embodiment is incorporated in the dashboard, the invention is not necessarily limited to this. Also in the case of the configuration of the above embodiment, for example, a door is attached to the front surface of the casing 2, the television main body 1 is stored in the casing 2 in an upward state, or the feeding mechanism 3 and the supporting mechanism are used. It is free to appropriately change the configuration of 4.

[Advantage of Invention] As described in detail above, the present invention is configured to detect the traveling state of the vehicle by the detection means, and rotate the display main body in the left-right direction by the support mechanism based on the detection result. Therefore, when the vehicle is running, by forcibly rotating the TV body in a direction invisible from the driver's seat, the driver may be distracted by the TV and neglect driving. It is possible to prevent this, and it is possible to view the television from the driver's seat or the passenger seat by freely adjusting the direction of the display body in an arbitrary direction when the vehicle is stopped. Not only that, the present invention stores the thin display main body in a horizontal state in the casing, and moves the display main body inside and outside of the casing by a feed mechanism. The main body is rotatably supported in the vertical direction, and when used, the display main body is sent out of the casing to the outside so that it can be vertically erected, so that it can be installed in other equipment. Can be incorporated into the dashboard of a vehicle such as a passenger car, so that the screen of the display body can be seen from the driver's seat or the passenger seat as long as the vehicle is stopped, and when not in use. The effect is that there is no fear of disturbing the driver's view.
