DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle display device in which a display unit can be projected and stored in a housing.

[0002]

2. Description of the Related Art A conventional in-vehicle display device has a DIN-sized housing used for car audio, and a display unit composed of a thin display device such as a liquid crystal is moved from the housing to a predetermined position. 2. Description of the Related Art There is known an in-vehicle display device that can be protruded and rotated, and a display unit can be stored in a housing when not in use, and the housing is mounted on a console of an automobile for use. In particular, the on-vehicle display device currently on the market is, as shown in FIG.
Display part 5a projects upward from inside the housing 5b and rotates upward,
In most cases, the display screen 5c can be stored with the display screen 5c facing downward when not in use, and for simplicity of operation, a series of operations of projecting, rotating, and storing the display unit 5a is automatically performed by a motor or the like. It is known that things are performed.
In this case, the inclination angle 5d of the display unit 5a at the time of use is generally set between about 60 ° to 110 °.

[0003]

The console shapes of current automobiles vary widely. Attempting to attach a conventional in-vehicle display device there causes various problems.

For example, when the display unit protrudes upward, there may be a vehicle type that hits a part of the console or presses an operation button such as an air conditioner of the vehicle. Also,
Problems also occur due to the DIN space, that is, the mounting position of the vehicle-mounted display device. For example, in the case of a vehicle in a place where the DIN space is high, if the display unit protrudes upward, it may be difficult for the occupant to see the display unit or obstruct the view of driving.

In general, the display device of the in-vehicle display device 5 is a liquid crystal and has a narrow viewing angle.
You need to look in front of c. For this reason, as shown in FIG.
In the case of a vehicle type in which the position of the space 2 is low, in order to make the display screen 5c face the front of the occupant 3, the display unit 5a must be able to be used in a state where the display unit 5a has fallen to near the horizontal. However, the display unit 5a of the conventional in-vehicle display device 5 has only an adjustment range of around 90 ° and does not fall to near the horizontal, so that it is very difficult for the occupant 3 to see. Therefore, the conventional in-vehicle display device cannot fully cope with the current automobile console.

In order to solve the above-mentioned problems, it is possible to select the upward and downward rotation of the display unit in accordance with the shape of the console, in addition to the upward and downward directions. It is desirable to be able to adjust from the viewpoint.

First, the following method is conceivable as a means for enabling the rotation of the display unit to be selected either upward or downward.

For example, a product in which the display moves only upward,
It is conceivable to prepare two types of products that move only downward. However, there are problems such as an investment amount and cost, and a problem that there is a possibility that the vehicle cannot be diverted when replacing a car. In fact, there is no example of preparing two types of products.

It is also conceivable to make the display unit rotatable up and down with one kind of product, but the mechanism may be complicated, and in particular, the display unit is automatically protruded and stored using a motor or the like. If so, the mechanism becomes very complicated. Furthermore, since the main purpose is to match the position of the display unit and the console, once the rotation direction is determined, the possibility of moving to the other is low, and the mechanism for this is likely to be wasted. . Next, it is considered that the inclination angle of the display unit can be adjusted from near the horizontal. In a conventional in-vehicle display device, in order to do this, it is necessary that the display unit protrudes and falls to near the horizontal. For this purpose, it is necessary to protrude the display unit 5a considerably as shown in FIG. 4 which is a side view of the vehicle-mounted display device shown in FIG. 3 and a top view thereof. Space must be secured. However, in general, there is a shift lever or the like in front of the console, so that the protruding display unit 5a
Is more likely to hit it. The internal structure of the in-vehicle display device 5 also has a limitation on the DIN space, and due to the recent increase in screen size, a space is required for a display device such as a liquid crystal display, and it is difficult to provide a mechanism for projecting a predetermined distance. is there. In particular, when rotating and projecting the display unit 5a using a motor or the like, a mechanism unit is usually provided at the portion 5e.
It is almost impossible to make room for a fall.

Therefore, the present invention does not require a complicated mechanism,
In particular, with the minimum modification of existing products, a product that can select the rotation direction of the display unit according to the vehicle type and can adjust the tilt angle when using the display unit arbitrarily from near horizontal with one type of product The purpose is to provide.

[0011]

According to the first aspect of the present invention, the display unit can protrude and be stored in the housing.
In an in-vehicle display device used by attaching the casing to a console of an automobile, at least an engaging portion is provided at a center portion of a side surface of the casing so that the casing can be attached in either up or down direction. 1 engaging portion, a second engaging portion for fixing the casing in a first position, and the first engaging portion for fixing in a position opposite to the first position. And a third engaging portion disposed symmetrically with the second engaging portion with respect to a shaft including:

According to the above configuration, the number of components is not increased, and the mounting can be performed while maintaining compatibility with the conventional one.
It is possible to mount the display unit on a console so that the display unit can be rotated upward or downward in various types of in-vehicle display devices. The engaging portion can be engaged with the projection by a groove or a screw.

In the vehicle-mounted display device according to the second aspect, the drive circuit can be driven in both forward and reverse directions.

According to the above configuration, the screen is normally projected regardless of whether the in-vehicle display device is mounted on the console either up or down.

According to a third aspect of the present invention, the tilt angle of the display unit in use can be adjusted from a horizontal state to an arbitrary position.

According to the above configuration, there is an effect that the occupant can easily see the vehicle-mounted display device even when the vehicle-mounted display device is mounted at a low position on the console without using a complicated mechanism and with a minimum change of an existing product.
