Abstract

PURPOSE:To improve burglar preventive effect on a vehicle by providing both a means sotring password numbers and a means judging whether or not an inputted password number is in a good agreement, and thereby using the actuating section of an on-vehicle acoustic device which can be remotely controlled as a password number inputting means. CONSTITUTION:When an actuating switch 4 is actuated in order to actuate an acoustic device 8 and a locking device 9 in a remote actuating device 1, let a transmitting code corresponding with the switch 4 be generated by a transmitting section 2 so as to let an infra-red photo-diode 3 be radiated. And let infra-red ray signals generated by the diode 3 be received by each pin photo- diode 5 and 10 of the acoustic device 8 and the locking device 9. And in the acoustic device 8 side, received signals are decoded by a receiving section 6 so as to let necessary control be assumed to an acoustic equipment 7. And in the locking device 9 side, received signals are amplified by an amplifier 11 so as to be decoded by a decoder section 12 thereafter so that they are compared with the password number stored in a non-volatile memory 14. And when both of them are in a good agreement, locking is released with a locking drive section 15 actuated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle-mounted audio device and a vehicle door locking device.

2. Description of the Related Art Hitherto, there have been known in-vehicle audio devices that are removable to prevent theft. These devices can be broadly classified into two types. That is, there have been proposed devices in which the entire device is removable, and devices in which only the operating portion of the device is removable. There is a known 62 system, such as the latter, in which only the operating section is detachable. In other words, there are those that can be operated remotely and those that have an operating section physically connected to the main body.

Furthermore, car door locking devices are generally mechanically locked using a key. In addition, a method has been proposed in which a switch is provided on the door handle without using a lock, and the lock is unlocked by inputting a code number.

Problems to be Solved by the Invention Among the conventional audio devices mentioned above, the method in which the entire device is attached and detached is because the device is large and heavy, making it inconvenient to carry it when getting out of a car. Therefore, a device in which only the steering gear part is attached and detached is easier to carry when leaving the vehicle, and is most suitable for theft prevention.

Regarding car locking devices, in conventional mechanical locking devices that use a key, the key can only be unlocked by inserting a needle or the like into the keyhole, and there is a risk of theft. For this reason, it is better to use an electronic lock system, but the method of installing a switch near the door handle and inputting the code number has the disadvantage that it is necessary to prevent others from knowing the code number. In other words, if someone knows the lock even at -degrees, that person can easily open the lock.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel locking system for an automobile, which makes it possible to eliminate the above-mentioned disadvantages inherent in the prior art.

Differences from the Prior Art in Section 6 of the Invention-E Compared to the conventional vehicle-mounted audio device described in cf), the present invention has a difference in that the present invention also has an operating function for locking the car door. That is, in contrast to the conventional in-vehicle audio device in which only the operating section can be detached and the main body can be remotely controlled by the operating section, the present invention is different from the previous device in that the operating section can also be used to unlock the car. different from.

Means for Solving the Problems In order to achieve the above object, the automobile locking system according to the present invention includes a remote control device that can also operate an in-vehicle audio device, and the locking device main body includes a remote control device. It has a signal receiving section, a decoder section, a match detection section that determines whether the sent signal is a correct recitation number, and a nonvolatile memory that stores the recitation number. It is constructed with two drive parts that open and close the.

Embodiments Next, preferred embodiments of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention, and is an example using infrared rays.

Referring to FIG. 1, the remote control f1=device 1 is the sound device 8.
and a device for operating the locking device 9. The remote control device 1 is equipped with an 8VI device 8 or a locking device 9 (it is equipped with a TIFR switch 4 for nesting). It is preferable from the viewpoint of occupying space to use one switch as the operating switch for the two devices.When the operating switch 1.l is set to 4if, the transmitter 2 generates a transmission code corresponding to that switch. , the infrared light emitting diode 1-3 emits a photoelectric signal.The infrared signal is received by the binocular diode 5 of the acoustic device 8 and the binphotodiode 1;IQ of the locking device 9. A locking device 9 decodes the signal received by the receiver 6 and performs necessary control over the audio equipment 7.
Then, the signal received by the binhole diode 1 () is amplified by the amplification section 11, and the signal is decoded by the decoder section 12.
'do. Then, a match detection section 3 determines whether the decoded signal matches the recitation number recorded in advance in the nonvolatile memory 1. If a correct signal is sent, the lock drive section 15 is operated to unlock the door.

FIG. 2 is a block diagram showing a second embodiment of the present invention.

Referring to FIG. 2, since the acoustic device 8 is the same as that in FIG. 1 of the first embodiment, the description thereof will be omitted.

Referring to FIG. 2, when the switch for the audio device 8 is operated using the operation switch 4, the signal is transmitted to the transmitter 2, and the light emitting diode 3 emits light. When the switch for the locking device is operated, the match detection circuit 13 determines whether or not the recitation number matches the password registered in advance in the non-volatile memory 14, and if they match, the transmitter 2 sends a message to the user.
A signal for unlocking is emitted by the light emitting diode 3.

In the locking device 9, the signal received by the binocular diode 10 is amplified and the width portion 11 is amplified, and the decoder portion 12 determines whether the signal for unlocking is 1 or less. If the signal is to open the lock, the lock driving section 15 is controlled to mechanically open the lock.

In this second embodiment, a non-volatile memory card is used as a remote controller.
Since it is disposed in the Y-packed stomach 1, the temperature characteristics required therefor are significantly lower than those of the first embodiment. That is, since the remote control device 1 is operated by a human being, it is sufficient if it operates at 140 degrees + 85 degrees (r). Therefore, the second embodiment uses a nonvolatile memory that is cheaper than the nonvolatile memory used in the first embodiment.
It is famous for its ability to do things. The first fruit 8 again! If a non-volatile memory with an operating range comparable to that of the second embodiment is used in the example, it is necessary to take measures to prevent the temperature of that part from exceeding the operating range of the non-volatile memory. In this way, the second embodiment has more features in terms of price.

However, in the second embodiment, the number of components mounted on the remote control device 1 is greater than that in the first embodiment, so the first embodiment is better in terms of miniaturization.

As described in detail, according to the present invention, the removable operation part of the in-vehicle audio device can be used as the key to the car, thereby preventing the audio device itself from being stolen and providing a complete locking system. Can be provided.

In other words, the operating part of the sound device is removable, so if you take it out when you leave the car, only the main body of the sound device remains inside the car, and you can install it in an inconspicuous place such as inside the dash board or under the seat. Possible 9 For this reason, the old person will not even know that such a sound device is installed, so it is possible to prevent theft.

Furthermore, according to the present invention, the locking system does not have a keyhole, so it is impossible to forcefully open the lock with a wire, and even if someone else learns your code number, you cannot hand over the remote control device. The effect is that no one else will be able to open the lock unless there is.
