[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive mechanism for a movable panel of an audio device, and more particularly to a drive mechanism of a movable panel suitable for a panel of a vehicle-mounted audio device having a liquid crystal display or the like.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a driving mechanism of a movable panel of a conventional on-vehicle acoustic device. The panel 21 is provided with an arc-shaped guide groove 21a provided therein and the in-vehicle audio device main body 2.
3 is movably supported by engagement with a pin 23a provided upright.

The segment gear 2 provided on the panel 21
1c meshes with the gear 22, and the rotation of the gear 22 moves the panel 21 from the position shown by the solid line to the position shown by the dotted line.

The upper and lower portions of the panel 21 are thin so that they do not buffer the front end 24 of the audio equipment when the panel 21 moves. When the panel 21 is at the position indicated by the dotted line, the recording medium insertion opening 25 is opened.

[0005]

In the conventional movable panel driving mechanism described above, the upper and lower portions of the panel 21 must be thinned, so that a thick display device can be arranged only at the center of the panel. However, there is a disadvantage that the display area is reduced and the visibility of the display unit is reduced.

The present invention has been made in view of the above points, and an object of the invention is to provide a movable panel driving mechanism capable of making the entire panel thicker.

[0007]

The drive mechanism for a movable panel according to the present invention is a drive mechanism for a movable panel disposed on the front of an audio equipment, wherein a lever is rotatably supported by a horizontal moving member, A pin erected at the rear end of the lever is engaged with a guide groove of the horizontal portion and the inclined portion provided on the fixing member, and the movable panel is rotatably supported at the front end of the lever and is movable. The guide groove provided on the horizontal moving member is engaged with a pin erected on the horizontal moving member, and at the initial stage of movement of the horizontal moving member, the pin erected on the rear end of the lever engages with the horizontal portion of the guide groove. Accordingly, the movable panel moves forward without changing its posture, and the movable panel is configured to rotate when the pin comes into engagement with the inclined portion of the guide groove.

[0008]

According to the drive mechanism of the movable panel of the present invention,
In the initial stage of the movement of the horizontal moving member, the movable panel moves forward without changing its attitude, so that the entire panel can be made thicker without damaging the end of the front end of the audio equipment.

Further, it is possible to open the recording medium insertion opening by rotating the panel after the panel has advanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A driving mechanism for a movable panel according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing an example in which the present invention is applied to a recording medium reproducing device of a vehicle-mounted audio device. As shown in the figure, the horizontal moving member 3 is supported by the chassis 5 so as to be movable in the horizontal direction.

That is, the pins 5 erected on the chassis 5
are engaged with the guide grooves 3c of the horizontal moving member 3 to movably support the horizontal moving member 3, and the rack 4 fixed to the horizontal moving member 3 is moved by the motor 6 to the worm gear 7, The gear 11 is engaged with the gear 11 rotated via the helical gear 8, the gear 9, and the gear 10.

The lever 2 is rotatably supported by a shaft 3a erected on the horizontal moving member 3, and a pin 2b erected on its rear end is engaged with a guide groove 5a of the chassis 5. A shaft 2a erected at the end of the lever 2 supports the panel 1 rotatably. The groove 1a of the panel 1 is engaged with a pin 3b erected on the horizontal moving member 3.

The figure shows the right support mechanism of the panel 1, but the left support mechanism is the same as the right support mechanism.

Next, the operation of the above mechanism will be described with reference to FIG. FIG. 2A shows a state in which the panel 1 is in a normal position for closing the front surface of the audio device main body 12, and at this time, the recording medium insertion port 14 is closed by the panel 1.

While the horizontal moving member 3 advances from the state shown in FIG. 2A to the state shown in FIG. 2B, the pin 2b erected on the lever 2 engages with the horizontal portion of the guide groove 5a. The lever 2 does not rotate. Therefore, the panel 1 moves forward without changing the posture and does not interfere with the front end 13 of the front end of the audio equipment.

The horizontal moving member 3 is moved from the state shown in FIG.
Is further advanced, the pin 2b engages with the inclined portion of the guide groove 5a, and the lever 2 rotates. At this time, since the panel 1 is sufficiently advanced, it does not interfere with the front end 13 of the front end of the audio equipment.

FIG. 2 (c) shows a state in which the horizontal moving member 3 has advanced to the end position. At this time, the recording medium insertion port 14 is opened so that the recording medium can be inserted. When the horizontal moving member 3 retreats, the panel 1 moves in a direction opposite to the above movement, and the recording medium insertion opening 14 is closed.

Although the embodiment has been described with reference to the case where the panel opens and closes the recording medium insertion opening, the invention is not limited to this. Is also possible.

[0019]

According to the drive mechanism of the movable panel of the present invention, the entire panel can be made thicker, so that a large-sized display device can be arranged on the panel, and the visibility of the display section is greatly improved. improves.
