Hereinafter, a monitor driving apparatus for a vehicle A / V system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view illustrating a monitor embedded in a case body in a monitor driving apparatus of a vehicle A / V system according to an exemplary embodiment of the present invention. FIG. 2 is a view illustrating a monitor driving apparatus of FIG. FIG. 3 is a side view of the monitor driving device of FIG. 1 in which the monitor is visible to a driver, and FIG. 1 is a plan view illustrating a state in which the movable body is connected to the rack gear unit in the monitor driving apparatus of FIG. 1, and FIG. 5 is a diagram illustrating a state in which the monitor is omitted in the monitor driving apparatus of FIG. 1. 1 is a plan view illustrating a state in which the left end of the size fisherman is in contact with the monitor A of the vehicle A / V system according to an embodiment of the present invention. As it is composed of a case body 100, movable body 200, a monitor chassis (M) and the connector body 300. The

One side of the case body 100 is opened, the horizontal guide groove 120 is formed in the longitudinal direction on the inner side and the rack gear portion 110 is provided in the longitudinal direction on the inner side.

The moving body 200 is a drive motor 240 that is rotated by an electrical signal to move horizontally along the horizontal guide groove 120 inside the case body 100, a worm gear inserted into the rotation shaft of the drive motor 240 241, the first gear 220 geared to the worm gear 241 so that the rotation axis is perpendicular to the rotation axis of the worm gear 241, the first rotation shaft is parallel to the rotation axis of the first gear 220. And a second gear 230 geared to the first gear 220 and geared to the rack gear unit 110, and having a third guide groove having a predetermined length parallel to the horizontal guide groove 120 on the side of the body. At the same time (A) is formed, the second guide groove (C) is formed, the wheel 250 is formed on the lower side of the body, the front of the body protrudes by a predetermined length is hinged to one side of the monitor chassis (M) Hinge coupling portion 210 is formed.

The monitor chassis M has a first guide groove B formed at one side thereof and is hinged to the movable body 200, and the connecting body 300 is the movable body 200 and the monitor chassis M. ), A third pin 330 inserted into the first guide groove B and guided, a first pin 310 inserted and guided in the second guide groove C, and the third The second pin 320 inserted into the guide groove A and the horizontal guide groove 120 is guided therein.

The first gear 220 is a helical gear, and the second gear 230 is a spur gear.

An operation of the monitor driving apparatus of the vehicle A / V system according to an embodiment of the present invention having the above configuration will be described with reference to the drawings.

First, as shown in FIG. 1, when the driving motor 240 is driven in a state in which the monitor chassis M is inherent in the case body 100, the worm gears 241 and the first and second parts fitted to the rotation shaft of the motor 240 may be used. As the gears 220 and 230 are interlocked, the movable body 200 moves to the front along the rack gear part 110 and is guided by the horizontal guide groove 120 to provide the second gear as shown in FIG. 2. The pin 320 is caught by the front end of the horizontal guide groove 120.

Subsequently, the moving body 200 continues to move forward, and as shown in FIG. 3, the second pin 320 moves to the rear of the third guide groove A, and thus the first pin 310. ) Moves to the rear of the second guide groove (C) at the same time the third pin 330 is moved to the front of the first guide groove (B), so that the monitor chassis (M) is raised at a certain angle and finally It is in the same state as 3.

On the other hand, the operation in which the monitor chassis M is inherent in the case body 100 as in the initial state, the drive motor 240 is driven in the direction opposite to the initial driving direction, the worm gear 241, the first, second gear 220 and 230 are also rotated in a direction opposite to the initial rotation direction, the moving body 200 is moved to the rear of the rack gear unit 110, the monitor chassis (M) and the moving body 200 in the reverse order to the operation described above Driven so that the monitor chassis (M) is embedded in the case body 100 as shown in FIG.

As described above, according to the monitor driving device of the vehicle A / V system according to the present invention, the monitor chassis is inherently embedded in the case body before driving, and then the moving body moves forward to drive the connecting chassis connecting the monitor chassis and the moving body. Since the pin is guided by the guide groove formed in the movable body and the monitor chassis, the monitor chassis is rotated and raised at a predetermined angle, so that the driver has a wide driving space.
