It provides a car audio, characterized in that it comprises a switch.

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

2 to 7 illustrate a car audio device 100 according to an embodiment of the present invention.

2 is a perspective view of a car audio device 100 according to an embodiment of the present invention, Figures 3 to 5 is an operating state diagram of the car audio device 100, Figure 6 is a view of the car audio device 100 7 is a plan sectional view, and FIG. 7 shows a front view of the car audio device 100. As shown in FIG.

As shown in FIG. 2, the car audio device 100 according to the present invention includes a main body 110 embedded in a cartridge formed in a vehicle body. The frame 120 is mounted on the front surface of the main body 110, and the front panel 125 is installed in the frame 120 to be tiltable. The front panel 125 is equipped with a plurality of knob assemblies 130 and operation buttons 170 for selecting various functions of the car audio device 100. In addition, the front panel 125 is provided with a liquid crystal display 140 for displaying a frequency or an operation mode. Reference numeral 127 denotes an open button. When the open button 127 is pressed, the front panel 125 moves in the width direction of the frame 120 and tilts in the outward direction of the frame 120.

Referring to FIG. 7, a tape insertion hole 280 and an eject switch 282 are provided at a predetermined front surface of the frame 120. By installing the tape insertion hole 280 in the frame 120 formed at the rear of the front panel 125, not only can the size of the display unit 140 be maximized, but also the design of the display unit 140. Can be designed in various ways. The eject switch 282 is used to withdraw the tape inserted into the tape insertion hole 280.

Referring to FIG. 3, a pair of guide ribs 270 coupled to upper ends of the front panel 125 are installed at both front upper ends of the frame 120, respectively. A guide slot 274 having a predetermined curvature is formed at the center of the pair of guide ribs 270. The guide slot 274 is formed to be curved in the outward direction of the frame 120 to facilitate the tilt movement of the front panel 125.

The front panel 125 is movably coupled to the guide rib 270 by a pair of hinge pins 272. One ends of the pair of hinge pins 272 are fixedly inserted into both upper ends of the front panel 125, respectively. In addition, the other ends of the pair of hinge pins 272 are inserted into the guide slots 274 so as to be movable. Thus, when the front panel 125 is tilted, the hinge pin 272 is moved along the guide slot 274.

In addition, the car audio device 100 according to the present invention is coupled to the front panel 125, the moving member 260 and the moving member 260 to linearly reciprocate to tilt the front panel 125 And a motor-gear assembly 200 engaged with the reciprocating motion of the moving member 260.

The moving member 260 is disposed below the inner side of the main body 110. Both front ends of the movable member 260 extend through the lower portion of the frame 120, and are coupled to both lower ends of the front panel 125 by hinge pins 264, respectively. In addition, a rack gear 262 engaged with the motor-gear assembly 200 is formed at one side of the movable member 260.

The gear-motor assembly 200 is a motor (210) mounted on the inner wall of the main body, a war worm gear 230, which is integrally coupled to the rotation shaft 220 of the motor 210, the war worm gear 230 A first gear 240 coupled to the first gear 240, and disposed between the first gear 240 and the rack gear 262 to transmit the rotational force of the first gear 240 to the rack gear 262. And a second gear 250 for transmitting. The motor 210 employs a forward and reverse motor capable of rotating in the forward and reverse directions.

In addition, the front wall 125 detects when the front panel 125 is fully open and transmits an electric signal to an electronic control unit (not shown), thereby tilting the front panel 125. A limit switch 115 is provided to allow stopping.

Car audio device 100 according to an embodiment of the present invention having the configuration as described above operates as follows.

First, when the user wants to listen to the cassette tape, when the user presses the open button 127 installed on the front panel 125, the electronic control unit connected to the open button 127 applies an operation signal to the motor 210. The motor 210 is operated in the forward direction.

The rotational force of the motor 210 is a rack gear formed integrally with the moving member 260 through the rotation shaft 220, the warworm gear 230, the first gear 250, and the second gear 250 ( 262, whereby the moving member 260 linearly moves out of the car audio device 100.

The movable member 260 is coupled to the lower portion of the front panel 125 by a hinge pin 264. Therefore, as shown in FIG. 4, as the movable member 260 moves outward of the car audio device 100, the lower portion of the front panel 125 also tilts outward of the frame 120. do. In this case, the hinge pin 272 provided on the front panel 125 is centered on the guide rib 274 from the top of the guide rib 274 along the guide slot 274 of the guide rib 270. The upper end of the front panel 125 moves to the center of the guide rib 274.

Here, the tilt movement means that the front panel 125 moves with a predetermined tilt with respect to the car audio device 100 or the frame 120, and has a similar meaning to the tilt movement or the rotation movement. .

Subsequently, when the moving member 260 completely moves outside of the car audio device 100, the upper portion of the front panel 125 moves to the lower portion of the guide slot 274. At this time, as shown in Figure 7, the tape insertion hole 280 formed in the frame 120 is shown. In this state, the user can insert a tape into the tape insertion hole 280 to listen to the desired music.

On the other hand, when the moving member 260 is completely moved to the outside of the car audio device 100, as shown in Figure 6, the limit switch 115 detects this to provide an electrical signal to the electronic control unit The electronic control unit stops the operation of the motor 210.

When the user inserts the tape into the tape insertion hole 280, a separate tape loading device (not shown) is driven to load the tape in the operating position, and the front panel 125 is as shown in FIG. It returns to its original position. The signal for returning the front panel 125 to its original position may be such that a sensor detecting the loading of the tape sends an electric signal to the electronic control unit to apply a driving signal to the motor 210. However, according to another embodiment of the present invention, the front panel 125 may be returned to its original position by driving the motor 210 using a separate operation button.

When the front panel 125 is returned to its original position, the motor 210 rotates in the reverse direction. Accordingly, the tilting operation of the front panel 125 is developed in the reverse direction, thereby returning the front panel 125 to the original position. Will be. Since the return operation is similar to the tilt movement operation of the front panel 125, a detailed description thereof will be omitted.

As described above, in the car audio device according to the present invention, since the tape insertion hole is not installed in the front panel, the size of the display unit formed in the front panel can be made large, and the design of the front panel can be variously designed. It has the advantage of being able to.

In addition, since the car audio device of the present invention can adjust the angle of the front panel, when the light is incident and it is difficult to identify the content displayed on the display unit, the car audio device can adjust the angle of the front panel to identify the display content. It has the advantage of being able to.

Although the present invention has been described based on the preferred embodiments, various modifications and improvements can be made within the scope of the technical idea of the present invention, and those skilled in the art will recognize that such variations and improvements also belong to the present invention. .
