Description

FRONT PANEL DRIVING APPARATUS FOR CAR AUDIO}

The present invention relates to a front panel driving apparatus of a car audio, and more particularly, a front panel driving apparatus for observing and manipulating a front panel when the information carrier is pulled out and inserted, and a car that allows the front panel to be pulled out and stored smoothly. A front panel drive for audio.

Car audio is a kind of audio device which is generally disposed in the front dashboard between the driver's seat and the passenger seat of the vehicle, and is limited in the vertical and horizontal widths according to the type of the vehicle.

In general, car audio includes a deck assembly composed of at least one of a cassette, a CD player, and an MP player inserted into a storage space of a dashboard.

Recently, an escutcheon portion is provided on the front surface of the deck assembly so as to be rotatable along the up and down direction, and a so-called flip down unit in which the front panel having a plurality of operation buttons and a display unit is coupled to the isker ceiling portion. The method is widely used.

1 is an exploded perspective view showing main parts of a conventional car audio. As shown, the front panel 141 is formed on the front surface of the deck assembly 110, in which the entrance 111 of the information carrier such as a compact disc, a mini disc, or a cassette tape is formed on the front surface. The panel engaging portion 121 in which the doorway 122 is formed so as to correspond to the doorway 111 of the information carrier so as to be rotated along the up and down direction, and rotatable along the up and down direction on the front surface of the panel coupling part 121. Issucheoncheon (Escutcheon) portion 131 to be coupled is provided.

Rotating shaft 123 is provided at both lower regions of the front surface of the panel coupling portion 121 to rotatably support the isker ceiling portion 131, and the isker ceiling portion 131 is gradually formed on the rotation shaft 123. A plurality of damping gears 125 are tooth-coupled to each other so as to rotate downward. A locking protrusion 126 is rotatably formed in one upper region of the panel coupling part 121 to prevent the front panel 141 from being rotated downward in a standing state.

Meanwhile, a display unit 142 is provided at the front center of the front panel 141 so as to output predetermined information, and both side edges of the isker ceiling unit 131 may be inserted into both sides of the front panel 141. Insertion grooves 144 are formed so that each can be. In the periphery of the display unit 142, a plurality of operation buttons 145 are provided to select / operate the functions of the deck assembly 110, and the corresponding area of the front upper engaging protrusion 126 of the front panel 141 is provided. The release button 147 is provided to release the locking state of the locking projection 126 so that the front panel 141 can be rotated downward.

By such a configuration, both side edge portions of the isker cloth portion 131 are inserted into the insertion grooves on both sides of the front panel 141 in a state where the isker cloth portion 131 is rotated downward with respect to the panel coupling portion 121. When the front panel 141 is rotated upward, the front edge of the front panel 141 is held by the locking protrusion 126 of the panel coupling unit 121 so that the front panel 141 is maintained in an upright state. .

When inserting or withdrawing information carrier such as CD, CD or cassette tape into the deck assembly 110, the release button 147 of the front panel 141 is pressed. When pressing the release button 147, the locking projection 126 in contact with the release button 147 is rotated to release the locking state with the front panel 141, the front panel 141 by the elastic force of the spring not shown It rotates downward about the rotation shaft 123. At this time, the damping gear 125 is to prevent the front panel 141 is rotated rapidly so that it can be gradually rotated. When the front panel 141 is rotated downward and the doorway 122 of the panel coupler 121 is opened, a CD, an MD, a cassette tape, or the like may be inserted or withdrawn through the doorway 122.

By the way, in the conventional car audio, the esker top portion 131 and the front panel 141 are formed to block the entrance and exit 122 on the front of the entrance and exit 122 of the information carrier such as CD, CD or cassette tape. Therefore, when the information carrier is pulled out or inserted, the front panel 141 and the isker top portion 131 are rotated downward, and after the withdrawal or insertion, the front panel 141 and the isker top portion 131 must be rotated upward again. There is discomfort. In addition, when the front panel 141 is rotated downward, there is a problem that it becomes difficult to observe and manipulate the display unit 142 and each operation button 145 formed on the front surface of the front panel 141.

Accordingly, it is an object of the present invention to provide a front panel driving apparatus of a car audio capable of observing and manipulating the front panel when the information carrier is withdrawn and inserted, and the withdrawal and storage of the support panel can be smooth.

Here, the inclination adjustment knob 25 may be configured in the form of a plurality of push buttons to correspond to each position detection sensor 51, or in the form of a single push button may be configured to select the inclination angle according to the number of pressing.

By such a configuration, when the inclination angle of the front panel 20 is to be adjusted, such as withdrawal and insertion of the CD 5 or cassette tape 8, the desired angle of the front panel 20 is controlled by operating the inclination adjustment knob 25. Select the angle of inclination. When the desired inclination angle is selected, the control unit 70 controls the pinion drive motor 43 to rotate in the direction in which the support panel 30 is drawn out.

When the pinion drive motor 43 starts to rotate, the pinion 42 is rotated and the rack teeth 41 coupled to the pinion 42 move relative to the guide rails 13 so as to be slidable to each guide roller 13. The support panel 30 supported by the contact is drawn out from the main chassis 10. At this time, the support panel 30 is withdrawn without the flow along the width direction by the interaction of the guide groove 36 and the guide protrusion 61, and the flow along the vertical direction by the buffer member 64 Is prevented.

On the other hand, when the support panel 30 is withdrawn from the inside of the main chassis 10, the front panel 20 is moved to the front lower side along the support panel 30, both upper and lower guides of the main chassis 10 As shown by a dotted line in FIG. 6, the inclined angle is allowed to move downward along the 11 and a predetermined inclination angle with respect to the main chassis 10, for example, an inclination angle in which the CD 5 or the cassette tape 8 can enter and exit. Have. That is, the inclination adjustment knob of the position detection sensor 51 disposed along the contact rail of the sensor switch 53 fixed inside the main chassis 10 and the sensor rail 35 formed on the upper surface of the support panel 30. When the position detection sensor 51 disposed at the position set by 25 is in contact with each other and the position detection signal is output, the controller 70 controls the driving of the pinion drive motor 43 to be stopped based on the position detection signal. The front panel 20 maintains the inclination angle set by the inclination adjustment knob 25 with respect to the main chassis 10. When the front panel 20 is to stand, the tilt control knob 25 may be operated to select the inclination angle at which the front panel 20 stands.

In the above-described and illustrated embodiments, the protrusions are formed in the upper regions on both sides of the front panel, and the upper and lower guides are formed in the upper and lower sides of the main chassis to guide the guides along the vertical direction.
