Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle audio device, and more particularly to a front face of the device body when the device body projects from a case mounted on a dashboard of a car during use and the device body is housed in the case. The present invention relates to a drive mechanism for a device body or a lid of an on-vehicle audio device in which a lid is covered.

[0002]

19 and 20 show an example of a drive mechanism for a device body and a lid of a conventional vehicle-mounted audio device. Reference numeral 3 shown in the drawing denotes a case, which is attached to the dashboard of the car. The device body 1 is placed so as to be movable back and forth in the case 3.

The lid 4 is rotatably supported by a shaft 3a provided upright on the case 3, and is connected to the device body 1 by an arm 5. That is, one end of the arm 5 is rotatably coupled to the shaft 4a erected on the lid 4, and the other end is rotatably coupled to the shaft 1a erected on the device body 1.

When no acoustic device is used, FIG.
As shown in (a) and (b), the lid 4 is rotated to a position where the opening of the case 3 is closed, and the device body 1 is pushed into the back of the case 3 by the arm 5. In this state, the panel 2 provided on the front surface of the device body 1 is hidden by the lid 4, the audio device is not visible, and theft is prevented.

When using the audio equipment, a finger is put in the notch 4b of the lid 4, the lid 4 is opened, and the equipment body 1 is pulled out. That is, as shown in FIGS. 20A and 20B, the acoustic device is used with the panel 2 protruding from the case 3 and the lid 4 opened downward. When the audio equipment is not installed in the car, a decorative panel is installed to hide the holes in the dashboard.

21 and 22 show an example of a drive mechanism for the device body and lid of a conventional on-vehicle audio device in which the device body and lid are driven by a motor. In this example, the device body 1 is driven by the motor 7, and the lid 4 is opened and closed by the device body 1.

That is, the lid 4 is rotatably supported by the shaft 3a erected on the case 3, and one end of the arm 5 is rotatably coupled to the shaft 4a erected on the lid 4 so that the arm 5 has The other end is rotatably connected to a shaft 1a provided upright on the device body 1.

The rotation of the motor 7 is transmitted to the drive member 8 by the gear train in the gear box 6. The drive member 8 is a shaft 8a
It rotates around and is erected on the drive member 8 and is provided with the long hole 3 of the case 3.
The pin 8b connected to b pushes and moves the device body 1. The drive member 8 is provided at a position deviated from the center of the device body in order to avoid the member 12 for wiring.

FIG. 21 shows a state in which the device body 1 is housed in the case 3 and the lid 4 is closed. The position of the device body 1 at this time is detected by pressing the switch 10 fixed to the case 3 by the device body 1.

FIG. 21 shows a state in which the audio equipment is not used. When the audio equipment is used, the motor 7 is started by pressing the switch 9 connected to the equipment body 1 by a cord, and the equipment body 1 is used. To the state shown in FIG. 22 in which the lid 4 is opened and the lid 4 is opened. The position of the device body 1 at this time is the switch 11 with the drive member 8 fixed to the case 3.
It is detected by pressing. The switch 9 is mounted at a position where the car can be touched by processing the car.

[0011]

In the above-described conventional vehicle-mounted audio equipment, the lid protrudes under the panel during use, so that the appearance is not good and it may be an obstacle when operating the shift lever. . Furthermore, when a force is applied from above the lid, the attachment part of the lid may be damaged.

21 and 22 in which the main body of the apparatus and the lid are driven by a motor, the rotation is transmitted to the driving member 8 by a gear fixed to the shaft of the driving member 8.
Since the inside of the car dashboard is narrow, the size of the gear box is also small and the pitch circle of the gear cannot be increased.

On the other hand, the device body 1 is heavy and requires a large thrust for driving, and the surface pressure applied to the gear fixed to the shaft of the drive member 8 and the transmission torque of the reduction gear train in the gear box are increased, Metal gears must be used for these gears. The metal gear has a problem that the cost is high and the gear sound is loud.

Further, the driving member 8 is a member 1 for wiring.
In order to avoid 2, the thrust is biased because it is provided at a position away from the center of the device main body, and not only a large thrust force is required, but also the device main body 1 is detected by the tilt switch 10 or the switch 11. There was a problem that the accuracy of the position of the body was difficult to obtain.

Further, the switch 9 for starting the motor 7 for driving the device body 1 has to be pulled out from the device body 1 with a cord and the car must be processed and mounted, which is troublesome and costly to mount. was there. Furthermore, if the switch 9 is installed in a conspicuous place, it may be stolen, and if it is installed in a conspicuous place, the operation becomes difficult.

The present invention has been made to solve the above-mentioned problems, and its purpose is to:
An object of the present invention is to provide an in-vehicle audio device that is inexpensive to manufacture, does not generate noise, and is easy to handle and has anti-theft protection.
