본 고안은 카오디오의 도난경보장치에 관한 것으로, 카오디오의 고정나사를 하나라도 풀면 경보부가 작동되도록 하여 도난을 경보하는 카오디오의 도난경보장치에 관한 것이다.The present invention relates to an anti-theft alarm device of the car audio, and relates to an anti-theft alarm device of the car audio to alert theft by loosening any of the fixing screws of the car audio.
일반적으로 카오디오의 도난경보장치는 비밀코드를 내장하여 도난당하더라도 카오디오자체의 비밀코드를 모르면 사용할 수 없도록 하는 제 1 방식, 기구적으로 카오디오세트를 이탈시킬 수 없도록 하는 제 2 방식, 최근 유럽지역에서 사용하는 디태처블 패널(Detachable Pannel) 방식인 제 3 방식, 카오디오에 핸들을 장착하여 항상들고 나닐수 있도록한 제 4 방식등이 알려져 있다.In general, a car audio theft alarm device has a built-in secret code, the first method of making it impossible to use the car audio itself without knowing the secret code of the car audio, and the second method of mechanically disabling the car audio set. The third method, which is a detachable panel method used in Europe, and the fourth method, which is equipped with a handle on a car audio, can always be carried.
그러나 제 1 방식은 비밀코드를 알아야만 작동이 가능하므로 카오디오정비소 등에서 정비 및 점검시 이를 운전자로 부터 일일이 확인하여야 하므로 번거로움이 있으며, 제 2 방식은 기구적인 브래킷을 설치하여야 하므로 설치가 어렵고 그에 따른 원가상승의 요인이 되며, 제 3 및 제 4 방식은 패널을 들고다니거나 카오디오세트를 그대로 들고다녀야 하므로 휴대에 따른 불편함이 있으며 또한 휴대자 본인이 분실하게 되는 경우도 있게 된다.However, since the first method can be operated only after knowing the secret code, it is inconvenient to check it from the driver at the time of maintenance and inspection at the car audio repair station, etc. Since the third and fourth methods require carrying a panel or carrying a car audio set as it is, it is inconvenient for carrying and also loses the user himself.
따라서 본 고안은 이러한 종래방식을 지양하고 카오디오를 자체의 하우징에 고정시키는 나사를 하나라도 빼면 경보를 울리도록 함을 특징으로 한다.Therefore, the present invention avoids this conventional method, and is characterized in that an alarm sounds when any screw is removed to fix the car audio to its housing.
즉, 카오디오의 고정나사와, 고정나사와 전기적으로 각각 접속되는 도전판으로 이루어지는 감지부와; 도전판의 각 출력과, 저항을 통해 제공받는 바테리전원을 오어게이트 입력으로 제공받도록 된 분석부와; 오어게이트출력에 따라 제어 작동되는 경보부로 이루어진 것이다.That is, a sensing unit comprising a fixing screw of the car audio and a conductive plate electrically connected to the fixing screw; An analysis unit configured to receive each output of the conductive plate and the battery power supplied through the resistor as an orgate input; It consists of an alarm that is controlled and operated according to the orgate output.
이하 본 고안을 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본 고안이 분해사시도로써, 차체와 연결된 하우징(13)에 카오디오(14)가 위치되며, 카오디오(14)의 사이드샤시에는 고정판공(15)을 가진 고정판(16)이 일체로 되며, 고정판(16)의 고정판공(15)과 대응하는 하우징(13)에 고정공(17)을 형성하며, 고정공(17)과 대응하는 하우징(13)의 이면부위에는 도전판(12)이 위치한다. (11)은 나사이다.1 is an exploded perspective view of the present invention, wherein the car audio 14 is positioned in the housing 13 connected to the vehicle body, and the fixing plate 16 having the fixing plate hole 15 is integrally formed in the side chassis of the car audio 14. The fixing hole 17 is formed in the housing 13 corresponding to the fixing plate hole 15 of the fixing plate 16, and the conductive plate 12 is formed on the rear surface of the housing 13 corresponding to the fixing hole 17. This is located. 11 is a screw.
제 2 도는 본 고안의 요부단면도로서, 고정판(16)의 고정판공(15)과 하우징(13)의 고정공(17)에서 나사(11)에 의해 결합되며, 나사(11)의 헤드 반대편(선단부)에는 도전판(12)이 위치한다.2 is a sectional view of the main part of the present invention, which is coupled by a screw 11 at a fixed plate hole 15 of the fixed plate 16 and a fixed hole 17 of the housing 13, and is opposite to the head of the screw 11. ), The conductive plate 12 is located.
제 3 도는 본 고안의 회로도로써, 설명의 편리상 나사(11)의 도전판(12)은 네모꼴로 도시한다.3 is a circuit diagram of the present invention, for convenience of description, the conductive plate 12 of the screw 11 is shown in a square.
본 고안의 감지부(10)는 접지와 연결된 나사(11)와, 도전판(12)이 각각 접속되도록 구성된다.The sensing unit 10 of the present invention is configured such that the screw 11 connected to the ground and the conductive plate 12 are connected to each other.
본 고안의 분석부(20)는 바테리전원(B+)과 저항(R1-Rn)과 오어게이트(21)를 구성요소로 이루어지며, 오어게이트(21)는 도전판(12)의 출력을 입력으로 제공받으며 동시에 저항(R1-Rn)을 통해 제공되는 바테리전원(B+)을 입력으로 제공받는다.The analysis unit 20 of the present invention includes a battery power source (B +), a resistor (R1-Rn) and an or gate 21 as components, and the or gate 21 is an input of an output of the conductive plate 12. At the same time, it is supplied with the battery power source (B +) provided through the resistors (R1-Rn).
본 고안에서의 경보부(30)는 오어게이트(21)의 출력에 따라 작동되도록 구성되며, 부저, 멜로디등의 경보신호등을 선택 출력시키도록 구성함이 바람직하다.Alarm unit 30 in the present invention is configured to operate in accordance with the output of the or gate 21, preferably configured to output the alarm signal, such as buzzer, melody.
이와같이 본고안이 구성 및 설치된 상태에서, 도둑질을 하기 위하여 카오디오(14)의 나사(11)를 돌려풀면, 제 2 도 상태에서 도전판(12)과 나사(11)와의 접촉이 분리된다. 즉, 제 3 도에서 나사(11)와 도전판(12)의 접촉이 분리되므로 도전판(12)에는 접지가 되지 않는다. 이때 나사(11)는 하나만 풀려도 풀린나사(11)와 접속된 도전판(12)은 접지가 연결되지 않으므로 그에 해당하는 오어게이트(21)의 입력에는 하이레벨이 인가된다.In this state in which the present invention is constructed and installed, the screw 11 of the car audio 14 is loosened for theft, and the contact between the conductive plate 12 and the screw 11 is separated in the second state. That is, since the contact between the screw 11 and the conductive plate 12 is separated in FIG. 3, the conductive plate 12 is not grounded. At this time, even if only one screw 11 is loosened, since the ground is not connected to the conductive plate 12 connected to the loosened screw 11, a high level is applied to the input of the corresponding or gate 21.
구체적으로, 평상시 카오디오(14)가 하우징(13)에 조립되어 있는 상태에서는 나사(11)와 도전판(12)이 제 3 도와 같이 각각 접속되어 있기에 오어게이트(21)에는 로레벨만 인가되게 된다. 즉, 비록 바테리전원(B+)이 저항(R1-Rn)을 통하여 오어게이트(21)의 입력단에 하이레벨을 제공한다하여도, 접지된 나사(11)와 도전판(12)이 접속되어 있기에 오어게이트(21)의 입력으로는 로레벨만이 인가되는 것이다. 이러한 상태에서 상기와 같이 어느하나의 나사(11)라도 카오디오(14)에서 풀리면(즉, 나사(11)와 도전판(12)의 접속이 차단되면) 오어게이트(21)의 입력단중의 하나에는 하이레벨이 인가된다. 따라서 오어게이트(21)의 특성에 따라 하이레벨이 경보부(30)에 인가되어 경보를 울리도록 한다.Specifically, in the state in which the car audio 14 is assembled to the housing 13, the screw 11 and the conductive plate 12 are connected to each other like the third diagram so that only the low level is applied to the ore gate 21. do. That is, even though the battery power source B + provides a high level to the input terminal of the or gate 21 through the resistors R1-Rn, the grounded screw 11 and the conductive plate 12 are connected. Only the low level is applied to the input of the gate 21. In this state, when any one of the screws 11 is released from the car audio 14 (that is, when the connection between the screws 11 and the conductive plate 12 is disconnected), one of the input terminals of the or gate 21 is as described above. High level is applied. Therefore, the high level is applied to the alarm unit 30 according to the characteristics of the or gate 21 to sound an alarm.
본 고안의 제 1 도에서는 고정판공(15) 및 고정판(17)과 도전판(12)을 각각 4개로 한정 도시하였으나, 이는 임의갯수(n개)로 변경 가능하게 제 3 도와 같이 표현하였다.In FIG. 1 of the present invention, the fixed plate hole 15, the fixed plate 17, and the conductive plate 12 are limited to four, respectively, but this is expressed as a third degree to be changed to an arbitrary number (n).
본 고안은 물론 도전판(12)과 오어게이트(21) 사이를 절단시켜 카오디오를 훔칠경우에도 상기와 같은 원리로 오어게이트(21)에 하이레벨이 인가되어 경보부(10)가 작동치 않게 된다.As well as the present invention, when stealing the car audio by cutting between the conductive plate 12 and the or gate 21, the high level is applied to the or gate 21 in the same principle as described above so that the alarm unit 10 does not operate. .
이상과 같이 본원 고안은 카오디오를 하우징에 고정시키는 나사를 하나라도 풀기만 하면 경보가 울리므로 도난을 방지할 수 있어 도난방지력이 뛰어나고, 또한 설치함에 있어서도 나사 뒷부분에 도전판만 설치하고 나머지는 콘트록박스등의 임의개소에 설치하면 되므로 설치가 용이하다.As described above, the present invention can prevent theft since only one screw that fixes the car audio to the housing can be used to prevent theft. Installation is easy because it can be installed in any place such as control box.
