DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle AV device, and more particularly to a panel storage mechanism suitable for a panel having a large display surface.

[0002]

2. Description of the Related Art Conventionally, an in-vehicle AV having a large display surface.
Some devices store the panel in the chassis when not in use. However, the display surface of the panel is horizontal and stored in the chassis so that the vertical sectional area of the storage space is reduced.

FIGS. 7 to 9 show examples of a panel storage mechanism of such a vehicle-mounted AV device. The illustrated chassis 2 is fixed to a vehicle console. The pins 3a, 3a,... Erected on both sides of the slide member 3 are engaged with guide grooves 2a, 2a provided in the chassis 2, and are supported by the chassis 2 so as to be movable in the horizontal direction.

A slide member 3 rotatably supports the panel 1 and also supports a rotary drive mechanism 4 and a horizontal drive mechanism 5. The gears 4a and 4b of the rotation drive mechanism 4 mesh with the sector gears 1a and 1a provided on the panel 1, and transmit the rotation of the motor to the panel 1 to rotate the panel 1.

The gears 5a and 5b of the horizontal drive mechanism 5 mesh with racks 2b and 2b provided on the chassis 2, and move the slide member 3 together with the panel 1 in the horizontal direction.

FIG. 8 shows a state in which the panel 1 is housed in the chassis 2. From this state, the horizontal drive mechanism 5 causes the slide member 3 to protrude from the console.
Move to the position shown in. In that state, the rotation drive mechanism 4
Pivots to a position where the panel 1 is marked by a two-dot chain line, so that the display surface of the panel can be seen by the user. When the panel is stored in the chassis 1, the reverse operation is performed.

[0007]

The depth dimension indicated by A in FIG. 7 of the chassis of the on-vehicle AV equipment is limited from the storage space. Also, a pin 3a for supporting the slide member 3
When the distance between the pin 3a and the pin 3a is increased, the stroke of the slide member 3 is reduced at a limited depth.

In the above-mentioned conventional panel storage mechanism, there is a problem that the interval between the pins must be reduced in order to increase the stroke of the slide member, and the supporting strength becomes insufficient. Further, there is a problem that the slide member rattles due to the small interval between the pins.
In addition, it is practically impossible to store a panel having a large display surface.

The present invention has been made in view of the above points, and an object of the present invention is to enable a panel having a large display surface to enter and exit a chassis.
Moreover, it is an object of the present invention to provide a panel storage mechanism for in-vehicle AV equipment having sufficient strength and capable of reducing backlash.

[0010]

According to the present invention, there is provided a panel storage mechanism for a vehicle-mounted AV device, wherein a panel is moved horizontally with its display surface in a horizontal state, and the panel is moved in and out of the chassis. As a result, in a panel storage mechanism of an in-vehicle AV device for making a display surface vertical, a first slide member horizontally supported by a chassis and a panel horizontally supported by the first slide member to rotate the panel. A second slide member freely supporting;
A rotation drive mechanism supported by the second slide member to rotate the panel, a horizontal drive mechanism supported by the second slide member and having a gear meshing with a rack provided on the first slide member; The first slide member is rotatably supported by the second slide member and engages with the second slide member and the chassis to rotate by the relative movement between the first slide member and the second slide member. It comprises a rotating member for moving in the same direction as the second slide member.

Further, in the panel storage mechanism of the in-vehicle AV equipment, the first or second slide member is pressed toward the end of the movement stroke by urging the rotating member with a spring. It is.

Further, in the panel storage mechanism of the on-vehicle AV equipment, one of the rotation drive mechanism and the horizontal drive mechanism is arranged inside and coaxially with the other drive shaft.

[0013]

According to the panel storage mechanism of the on-vehicle AV equipment of the present invention, the first slide member is driven in the same direction as the second slide member by the rotation of the rotation member. The movement distance of the first slide member and the second slide member is added to the movement distance of the first slide member and the second slide member.

Therefore, even if the movement stroke between the first slide member and the chassis and the movement stroke between the second slide member and the first slide member are reduced, the second stroke is not affected.
The distance by which the slide member moves with respect to the chassis can be increased, so that a panel having a large display surface can be stored.

Further, if the rotary drive mechanism and the horizontal drive mechanism have gears on both sides, long drive shafts for connecting the gears are required, but one drive shaft is provided inside the other drive shaft. By arranging the shafts, the space occupied by both drive mechanisms can be reduced.

Further, the rotating member is rotated by the movement of the second sliding member to drive the first sliding member in the same direction as the driving of the second sliding member, but applies a torque to the rotating member. Thus, the second slide member and the first slide member can be driven in the same direction.

If a spring is provided at the end of movement of the second slide member and the first slide member so that the rotation member presses them toward the end of movement, the spring is biased by the elastic force of the spring. Since each of the slide members is pressed against the support, rattling of the slide members when the panel is stored and used is eliminated.
