Description

Monitor deflection device of audio visiual for automobile

The present invention relates to a vehicle audio visual, and more particularly, to a monitor control apparatus for a vehicle audio visual in which the monitor of the audio visual has a left-right direction angle by electric motor.

In general, an audio visual (AV), which is an audio and video reproducing apparatus, is installed in a vehicle to seek convenience of a driver or a passenger.

The audio visual is provided with a monitor for reproducing a video signal on the front of the main body having a deck, which is an audio player, and an electronic component organically coupled thereto.

However, the conventional AV has a direction angle upward and downward based on the rotation point that the monitor is fastened to both sides of the main body, there is a problem that the passengers in the left and right directions at a predetermined position of the vehicle AV is difficult to watch.

In order to solve this problem, it is conceivable to install a rotating plate having a rotating means at a predetermined position of the vehicle and to mount the AV main body on the upper surface of the rotating plate, but it is structurally complicated and occupies an installation area, thereby making the vehicle more narrow. .

The present invention has been made to solve the above problems, an object of the present invention is to provide a monitor control device for a vehicle audio visual that is equipped with an electric gear system inside the body to operate the left and right angles.

The present invention for realizing the above object is provided with a monitor for reproducing a video signal on the front of a main body having a deck that is an acoustic regenerator and an organically coupled electronic device in the vehicle audio visual mounted on a predetermined position of the vehicle, Is a means for achieving the left or right direction angle, the main body is hingedly coupled to the steering plate fastened to the back of the monitor so as to freely rotate left and right, and the forward and reverse rotation-free electric motor built into the main body to provide power by an external power source, A worm provided on the rotating shaft of the motor, a worm gear freely mounted on a fixed member fastened to a predetermined position of the main body so as to rotate in engagement with the worm, a spur gear integrally provided with the worm gear, and a spur gear in coordination with the monitor Arc shaped internal gear that is inscribed to the spur gears to form a right and left angle to the steering plate The characteristic configuration.

The technical idea of the present invention by the above characteristic configuration is to provide the rotational force to the steering plate fastened to the monitor through the power system of the motor to achieve the left and right direction angle of the monitor.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

In the drawings, the present invention provides a conventional configuration in which a main body 10 incorporating a deck, which is an acoustic regenerator, and an electronically coupled electronic device, and a monitor 20 for reproducing an image signal in front of the main body 10 are provided.

In the above conventional configuration, the present invention is characterized in that the monitor 20 provides a means for achieving a direction angle of left or right.

Means for setting the direction angle of the monitor 20 is coupled to the main body 10 and the main body 10 coupled to the steering plate 30 fastened to the rear surface of the monitor 20 by the hinge 32 so as to freely rotate left and right. Reverse rotation free motor 40, built-in to provide power by an external power source, the worm 44 provided on the rotary shaft 42 of the electric motor 40, and the main body 10 to rotate in engagement with the worm 44 The worm gear 46 freely mounted on the fixing member 60 fastened to a predetermined position, the spur gear 48 integrally provided with the worm gear 46, and the spur gear 48 are rotated in parallel with the monitor 20 It consists of an arc-shaped internal gear 50 which is inscribed in the spur gear 48 and fastened to the steering plate 30 so as to form a right and left direction angle.

The fixing member 60 is fastened to the main body 10 with a screw 70. The electric motor 40 is firmly fixed to the fixing member 60, and the worm gear 46 is freely fixed to the rotation.

In addition, the arc-shaped internal gear 50 may vary in diameter depending on the rotation angle of the monitor 20.

In addition, the steering plate 30 is fastened with screws 70 on the back of the monitor 20, and in order to set the direction of the monitor 20 to the left or right on the front of the main body 10 adjacent to the monitor 20. It is provided with a button for forward and reverse operation of the electric motor 40, but is not shown in the drawings.

Therefore, according to the present invention, the electric motor 40 rotates forward when the user presses a button when the monitor 20 is set to the left side for viewing while the monitor 20 faces the front as shown in FIG. 2.

When the electric motor 40 operates, the worm 44 and the worm gear 46 rotate along the rotation shaft 42. The spur gear 46 integrally provided in the worm gear 46 rotates in engagement with the internal gear 50.

The internal gear 50 rotates clockwise on the drawing.

Therefore, the steering plate 30 to which the internal gear 50 is fixed rotates as shown in FIG. 3 with respect to the hinge 32 fastened to the main body 10, and the monitor 20 rotates to the left side.

On the other hand, when setting the direction angle to the right of the monitor 20 in Fig. 2 or 3 state, when the button is operated, the electric motor 40 is rotated in reverse and the gear system is rotated in reverse.

The present invention has the effect that the monitor can be adjusted by the electric left and right angles, the convenience and visibility that the passenger can watch the monitor in the desired position.
