JPH09330487A - Device for preventing on-vehicle audio burglar - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent burglar by using a smoke plate in front of an operation panel so that display can not be seen owing to the smoke plate when an ACC of a car is OFF and camouflaging the car as it does not have an audio without removing the operation panel when a driver leaves the car. SOLUTION: A smoke plate 7 is stuck to a fixed panel 6, and the front of the operation panel is entirely covered with the plate 7. A display tube 9 which is mounted to a base plate 8 is provided on a rear side of the plate 7, and current is supplied from a main body. Also, a photodetector 10 and LED 11 are provided on a side of the plate 8. The inside display tube 9 (a segment, etc.) is hard to be seen externally when an ACC of a car is OFF by setting the plate 7 on its darker side, and the audio looks as if it did not work at a glance. Thereby, burglar of car audio can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onboard audio antitheft device for preventing onboard audio theft.

[0002]

2. Description of the Related Art FIGS. 4 (a) to 4 (c) show the structure of a conventional on-vehicle audio theft prevention device. Figure 4 (a)
As shown in (c) to (c), the operation panel 1 is electrically connected to the main body 2 by the connector 4, and can be detached from the main body 2 by pressing the release button 3. At this time, since power is not supplied to the operation panel 1, the user carries it out of the vehicle, and the security LE is attached to the front portion of the main body 2 left in the vehicle compartment.
D5 flashes, indicating that there is no operation panel.

[0003]

However, the above-mentioned conventional antitheft device requires parts such as the release button 3, the release mechanism, and the connector 4 as compared with the fixed type in which the operation panel 1 is not removed from the main body 2, Further, it is necessary to pay close attention to electrical connection between the main body 2 and the operation panel 1 via the connector 4, which makes the design difficult. Further, it is troublesome for the user to carry the operation panel 1 all the time. Further, with respect to the 2DIN size car audio system, the operation panel is too large to carry, and the anti-theft measures are not taken.

The present invention solves the above-mentioned conventional problems, and prevents theft by making a camouflage so that there is no audio in the passenger compartment without removing the operation panel when the driver's vehicle or the like leaves the vehicle. Therefore, it is an object of the present invention to provide an on-vehicle audio theft prevention device capable of achieving simplification of the configuration, elimination of the troublesomeness of carrying, and the like.

[0005]

In order to achieve the above object, the present invention uses a smoke plate on the front surface of an operation panel so that the display cannot be seen by the smoke plate when the ACC of the vehicle is OFF. It is a thing.

Thus, an on-vehicle audio antitheft device is provided which is capable of preventing theft without removing the operation panel and simplifying the structure and eliminating the trouble of carrying. can get.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is characterized in that the front surface of the operation panel is covered with a smoke plate and the
The display is not visible due to the smoke board when is OFF, and the display is visible through the smoke board only when the ACC of the car is ON. When the ACC of the car is OFF, the display of the console is displayed. The audio is unnoticeable, and at first glance it looks like a car without audio, and has the effect of preventing theft.

According to the second aspect of the present invention, the LED is provided on the back side of the smoke plate so that the LED blinks when the ACC of the vehicle is OFF. By blinking the LED from the back of the smoke board when it is off, it seems like the conventional anti-theft method, even though it has audio, the operation panel has been removed and it seems that it can not be used even if it is stolen. Has the effect of.

Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) FIGS. 1 to 3 show an anti-theft device for an in-vehicle audio according to an embodiment of the present invention. FIG. 1 is an exploded perspective view of a front portion of an operation panel side, and FIGS. )
3A and 3B are explanatory diagrams showing how the display unit looks, and FIGS. 3A and 3B are explanatory diagrams of an audio operation example.

In FIG. 1, 6 is a fixed panel, and a smoke plate 7 is attached to this fixed panel 6, and the entire front surface of the operation panel is covered with the smoke plate 7. A display tube 9 mounted on a substrate 8 is provided on the back side of the smoke plate 7, and power is supplied from a main body 12 (see FIG. 3). Further, a light receiving element 10 and an LED 11 are provided on the side of the substrate 8.

By setting the smoke plate 7 to a dark color, the display (segments, etc.) of the inner display tube 9 is difficult to see from the outside when the ACC of the vehicle is OFF.
As shown in FIG. 2A, it can be made to seem that the function as audio is not fulfilled at first glance.

When the ACC of the car is turned on, the display tube 9 emits light, and the smoke plate 7 is lit as shown in FIG. 2 (b).
It is also visible through and the user can see the display.

Further, an LED 11 is provided on the substrate 8 so that the vehicle A
By blinking when CC is OFF,
As shown in (c), the display is not visible from the outside,
It seems that only the LED 11 is blinking, and it can be thought that the conventional anti-theft measure (remove the operation panel) is taken.

As shown in FIG. 3A, the audio operation may be performed by remote control operation by combining the light receiving element 10 and the remote control unit 13, or as shown in FIG. 3B. , Touch panel 1
4 may be used as the operation method.

[0015]

As described above, according to the present invention, by using the smoke plate on the front surface of the operation panel, when the ACC of the vehicle is OFF, it is possible to camouflage without audio and prevent theft. Therefore, since it is not necessary to remove the operation panel and carry it around, it is possible to simplify the configuration and eliminate the troublesomeness of carrying around.
