Description

오작동 및 작동불량 방지를 위한 자동차용 경보기{Alarm of Automobile for preventing false-operation and non-operation} Alarm of automobile for preventing false-operation and non-operation}

본 고안은 자동차용 경보기에 관련된 것으로, 일반적으로 경보기는 도난을 감지하여 경보음을 내거나, 리모콘에 의한 자동차 문의 개폐 시에 일정한 신호음을 발생한다.The present invention relates to an automobile alarm, and generally, the alarm detects theft and emits an alarm sound, or generates a constant beep when the door is opened and closed by a remote controller.

도 1은 자동차용 경보기의 정면도로, 본체(100)와 스피커(200), 연결부(150)로 구성되며, 스피커(200)는 연결부(150)에 의해 본체(100)에 강제 끼움 형식으로 연결된다.1 is a front view of the vehicle alarm, the main body 100 and the speaker 200, the connection portion 150, the speaker 200 is connected to the main body 100 by a fitting portion 150 in the form of a forced fit. .

도 2에 도시된 바에 따라 자동차용 경보기의 구성을 살펴보면 다음과 같다.Looking at the configuration of the car alarm as shown in Figure 2 as follows.

경보기는 다이오드(120), 저항(130) 등 전자부품을 포함하는 인쇄회로기판(110)을 포함하는 본체(100)와 스피커본체(210), 반사덮개(220), 공기관(240), 음방출관(250) 및 피에조(압전체)(260)을 포함하는 스피커(200)와 상기 인쇄회로기판(110)과 상기 피에조(260)를 전기적으로 연결하는 연결선(140)으로 구성된다.The alarm device includes a main body 100 including a printed circuit board 110 including an electronic component such as a diode 120, a resistor 130, a speaker main body 210, a reflective cover 220, an air tube 240, and a sound emitting tube. Speaker 200 including a 250 and a piezo (piezoelectric) 260 and a connecting line 140 for electrically connecting the printed circuit board 110 and the piezo 260.

피에조(260)를 포함한 스피커(200)는 상기 연결부(150)를 통해 본체(100)에 연결되고, 본체 내에 인쇄회로기판(110)은 연결선(140)을 통해 피에조(260)에 연결되어, 인쇄회로기판(110)에서 발생한 전기적신호를 피에조(260)에 전달되게 된다.The speaker 200 including the piezo 260 is connected to the main body 100 through the connection unit 150, the printed circuit board 110 in the main body is connected to the piezo 260 through the connection line 140, printing The electrical signal generated from the circuit board 110 is transmitted to the piezo 260.

외부 자극이 감지되면 다이오드(120), 저항(130) 등이 설치된 인쇄회로기판(110)은 전기적신호를 발생시키고, 이 전기적신호에 의해 피에조(260)가 진동하게 되면, 스피커본체(210)와 피에조(260) 사이 공간의 공기가 진동하고, 이러한 공기의 진동은 공기관(240)을 통해 전달되어, 반사덮개(220)와 음방출관(250)을 통해 외부로 전달되어 작동하게 된다.When the external stimulus is detected, the printed circuit board 110 including the diode 120 and the resistor 130 generates an electrical signal, and when the piezo 260 vibrates by the electrical signal, the speaker body 210 and The air in the space between the piezo 260 is vibrated, the vibration of the air is transmitted through the air tube 240, it is transmitted to the outside through the reflective cover 220 and the sound emitting tube 250 to operate.

일반적으로 자동차에 사용되는 경보기는 중량이 가벼워야 하기 때문에 플라스틱 재질로 만들어져 본체(100)와 스피커(200) 부분이 연결부(150)에 의해 연결되고, 본체(100) 내부에 인쇄회로기판(110)이 장착하게 된다. In general, an alarm used in a vehicle should be light in weight so that the body 100 and the speaker 200 are connected to each other by the connection part 150, and the printed circuit board 110 inside the body 100. Will be fitted.

그런데 경보기를 자동차에 부착하는 과정이나 자동차를 운행하는 과정에서 연결부분의 미세한 틈을 통해 누수현상이 발생하고 자연적인 습기에 전자부품이 노출되게 된다. 또한 자동차 운행에 따른 차체의 진동에 의해 경보기 내 인쇄회로기판(110)에 부착되어 있는 다이오드(120), 저항(130) 등의 전자부품이 인쇄회로기판(110)으로부터 분리되는 경우가 생긴다. 이러한 현상은 경보기의 오작동 및 작동 불량으로 이어지게 된다However, in the process of attaching an alarm to a car or driving a car, leakage occurs through minute gaps in the connection part and electronic parts are exposed to natural moisture. In addition, electronic components such as the diode 120 and the resistor 130 attached to the printed circuit board 110 in the alarm may be separated from the printed circuit board 110 due to vibration of the vehicle body due to driving of the vehicle. This phenomenon leads to malfunction and malfunction of the alarm.

본 고안은 이러한 문제점을 해결하기 위한 것으로서, 경보기 내부 회로기판(110)을 수지를 사용하여 포팅(potting) 함으로써 누수 및 습기에 따른 경보기의 오작동과 진동에 따른 전자부품의 분리에 의한 작동불량 방지를 목적으로 한다. The present invention is to solve this problem, by potting the internal circuit board 110 of the alarm using a resin (potting) to prevent the malfunction of the alarm due to leakage and moisture due to leakage and separation of the electronic components due to the vibration caused by separation. The purpose.

본 고안은 도 3에 도시된 바와 같이 경보기 내에 인쇄회로기판(110)을 장착하고 그 위에 수지를 사용한 포팅을 행한다. The present invention mounts the printed circuit board 110 in the alarm as shown in FIG. 3 and performs potting using resin thereon.

본 고안에 따른 경보기는 다이오드(120), 저항(130) 등 전자부품을 포함하는 인쇄회로기판(110)을 포함하는 본체(100)와 스피커본체(210), 반사덮개(220), 공기관(240), 음방출관(250) 및 피에조(압전체)(260)를 포함하는 스피커(200), 상기 인쇄회로기판(110)과 상기 피에조(260)를 전기적으로 연결하는 연결선(140)과, 인쇄회로기판(110)을 포팅하는 수지층(300)으로 구성된다.The alarm device according to the present invention includes a main body 100 including a printed circuit board 110 including an electronic component such as a diode 120, a resistor 130, a speaker body 210, a reflective cover 220, and an air pipe 240. ), A speaker 200 including a sound emitting tube 250 and a piezoelectric (piezoelectric) 260, a connecting line 140 for electrically connecting the printed circuit board 110 and the piezo 260, and a printed circuit board It consists of the resin layer 300 potting 110.

포팅에 사용되는 수지는 우레탄수지, 에폭시수지 등 절연성을 가지는 조건에서 그 종류가 제한되지 않는다. 포팅된 수지층(300)의 두께가 전자부품을 전부 덮게 되는 경우 발열현상으로 인해 경보기의 성능을 저하시키게 되므로, 수지층(300)의 두께는 습기 등으로부터 전자부품을 보호하고 전자부품의 접착을 진동으로부터 유지할 수 있을 정도인 인쇄회로기판(110)으로부터 5~10밀리미터 사이로 유지되는 것이 바람직하다. The resin used for the potting is not limited in its kind under conditions having insulation such as urethane resin and epoxy resin. When the thickness of the potted resin layer 300 covers all the electronic components, the performance of the alarm is degraded due to heat generation. Therefore, the thickness of the resin layer 300 protects the electronic components from moisture and the adhesion of the electronic components. It is preferably maintained between 5 and 10 millimeters from the printed circuit board 110 that can be maintained from vibration.

수지층(300)을 사용한 포팅은 누수나 습기로부터 전자부품을 보호하여 오작동을 막고, 접착력이 있어 차체 진동에 의한 전자부품이 인쇄회로기판(110)으로부터 분리되는 것을 방지할 수 있다.Potting using the resin layer 300 protects the electronic components from leakage or moisture to prevent malfunctions, and has an adhesive force to prevent the electronic components from being separated from the printed circuit board 110 due to vehicle body vibration.

이상에서는 본 고안의 바람직한 실시예에 한하여 설명하였으나, 당업자에 의해 다양하게 수정 또는 변경될 수 있음은 물론이며, 그러한 수정이나 변경도 본 고안의 기술적 사상을 바탕으로 하는 한 본 고안의 권리범위에 포함됨은 물론이다.In the above description of the preferred embodiment of the present invention, but can be variously modified or changed by those skilled in the art, of course, such modifications or changes are included in the scope of the present invention based on the technical spirit of the present invention. Of course.

본 고안에 따르면, 종래 경보기에서 발생할 수 있는 누수 및 습기에 따른 오작동과 전자부품 탈착에 따른 작동 불량을 방지할 수 있어, 경보기의 성능을 향상시킬 수 있다. According to the present invention, it is possible to prevent the malfunction due to leakage and moisture that can occur in the conventional alarm and the malfunction caused by the removal of the electronic components, it is possible to improve the performance of the alarm.
