The present invention relates to an automotive A / V set, and more particularly, to an automotive A / V set that enables viewers to see the image on the monitor at a glance even when the tape deck is loaded or removed from the tape deck.

A 4-inch TFT LCA and a tape deck for automobiles can be connected to TV, audio, and video CA / VTR, allowing the monitor to stand out in a car A / V set that selectively performs A / V / VTR functions. Since the monitor is installed to move in and out of the tape deck, the angle between the eye and the screen of the monitor becomes small when the monitor is moved forward to mount or remove the tape from the tape deck.

You cannot enjoy the picture of the monitor properly.

Accordingly, it is an object of the present invention to provide a monitor loading device for an automotive A / V set that enables viewers to see the image displayed on the monitor at a glance even when the tape deck is mounted or removed from the tape deck.

The main feature of the present invention is that the monitor is pivotally supported at the tip of the slide chassis that emerges in the front and rear directions by a loading device to be described later, so that the pivot can be tilted at a desired angle toward the back.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the automobile A / V set has a tape deck assembly 2 built into the casing 1, and a monitor 3 is provided on the front of the casing 1.

The present invention supports the monitor (3) by the pivot (5) at the tip of the slide chassis (4), which is haunted in the front and rear direction by a loading device to be described later so that the monitor (5) can be tilted at a desired angle toward the back. It is made up.

The slide chassis 4 is loosely fitted to the front and rear two guide pins 6 and 7 located on the horizontal line at the lower side of the casing 1 to receive the sliding guide in the front-rear direction. Guide grooves 4a guided by the guide pins 6 and 7 are elongated in the front and rear directions.

3 is a plan view of a drive unit of the monitor loading apparatus, and FIG. 4 is a front view thereof.

As shown in these figures, a gearbox 16 is installed at the bottom of the casing 1. The gear box 16 is provided with a motor 9 equipped with a worm gear 10 at its shaft end. This motor 9 is parallel to the direction of action of the slide chassis 4.

In addition, the worm wheel 10 is meshed with the worm gear 10, and the small gear 12 provided on the worm wheel 11 and the shaft 17 meshes with the standby gear 13 and the standby gear 13. The rack 15 is connected to the rack gear 14 formed coaxially with the.

Here, the small gear 12 is located above the worm wheel 11 on the shaft 17.

The worm gear 10, the worm wheel 11, the small gear 12, the standby gear 13, and the rack gear 14 are all protected by one gear box 16.

The rack 15 is installed in the slide chassis 4, the direction of which is parallel to the direction in which the slide chassis 4 emerges.

Then, a felt 18 is inserted between the worm wheel 11 and the small gear 12 to be inserted into the shaft 17, and the worm wheel 11 supports the bottom with a compression spring 19.

On the other hand, the forward limiting contact switch 22 and the return limiting switch 23 are provided on the gear box 16, and the contacts 24 and 25 selectively contacting the switches 23 and 24 on the rack 15 are also provided. Install.

In the present invention configured as described above, the motor 9 operates when the external button is operated and turned on. The driving force of the motor 9 is transmitted to the rack 15 through the worm gear 10 through the upper wheel 11, the small gear 12, and the standby gear 13 and the rack gear 14.

Accordingly, the slide chassis 4 pushes the bottom of the monitor 3 forward while moving in the direction of arrow 'D' of FIG. At this time, the upper end of the monitor (3) is guided by the guide groove 21 according to the degree pushed down almost vertically so that the horizontal movement is not made and the top is tilted obliquely backward.

As such, even when the monitor 3 comes close to the viewer's eye, the angle between the eye and the screen is large, so that the entire screen enters the field of view, so that viewing is easy.

When the rack 15 goes straight by a predetermined distance, the contactor 24 approaches and turns off the forward limiting contact switch 22. Then, the power supplied to the motor 9 is cut off and the monitor 3 stops the series of forward loading operations.

When the monitor 3 moves forward as shown in FIG. 2 and stops in the tilted state, the motor 9 reverses when the button is operated in reverse. The reverse power is also placed on the rack 15 via the worm gear 10, the worm wheel 11, the small gear 12, the standby gear 13, and the rack gear 14.

At this time, the slide chassis 4 moves backward in the d direction in FIG. 2 to raise the monitor 3. The standing operation of the monitor 3 stops the operation of the motor 9 as the other contactor 25 contacts the reverse limiting contact switch 23 and turns off when the rack 15 reaches the end point of return. And a series of monitor standing operations end there.

After the small gear 12, the force greater than the compression spring 19 is applied to the load, if the load is applied by the felt 18, the sliding phenomenon occurs due to the felt 18, the small gear 12 in the shaft 17 is turned away from the motor 9 Overload damage is prevented.

In order to prevent overload of the motor 9, a photo sensor 26 is installed on the gear box 16, and a reflector 27 is attached to the standby gear 13. In this case, when the standby gear 13 and the reflector 27 do not rotate even while a current flows in the motor 9, the porter sensor 26 detects this and stops the current of the motor 9 to cause burnout. Relief from damage.

As described above, the present invention advances the monitor so that the screen that enters the monitor at a glance can be tilted as much as possible within a predetermined angle range, so that an image that appears on the monitor even when the monitor is advanced to insert or remove a tape in the tape deck I can see it well.

In addition, since the front part loaded with 4 TFT LCD is loaded, a predetermined space formed at the top of the A / V set for automobiles can be utilized as a tape window for the tape deck, and when the monitor is exposed to advance by simple button operation, Since it is standing backwards, operation convenience is great.

Furthermore, since the motor is automatically stopped when an external force is applied to the monitor, the built-in component protection is excellent.
