Description

충격감지 장치{An impact sensing apparatus}An impact sensing apparatus

본 발명은 충격감지 장치에 관한 것으로서, 특히 충격에 취약한 전자기기 또는 통신기기에 물리적인 충격이 가해졌는지를 감지하기에 적합한 충격감지 장치에 관한 것이다.The present invention relates to a shock sensing device, and more particularly, to a shock sensing device suitable for sensing whether a physical shock is applied to an electronic device or a communication device that is vulnerable to shock.

일반적으로 충격감지 장치는 정밀 전자기기 또는 통신기기, 정밀 검측기기 등 동작의 정확성과 신속성을 요하는 기기에 많이 사용된다.In general, the shock detection device is widely used in devices requiring precision and speed of operation, such as precision electronic devices or communication devices, precision detection devices.

이러한 기기들은 외부의 충격에 대해 매우 민감하게 반응하고, 충격에 취약한 문제점이 있으므로 충격감지 장치를 사용하여 기기들의 보관 및 사용과정에서 외부의충격이 기기에 가해지는 것을 차단하게 된다.These devices react very sensitively to external shocks and are vulnerable to shocks, which prevents external shocks from being applied to the devices during the storage and use of the devices by using shock sensing devices.

대개 이러한 기기들은 충격 감지장치로서 외부에서 충격이 가해지는 지의 여부를 진동 감지센서, 가속도 감지 센서 등의 센서를 이용하고, 외부에서 충격이 가해지면 센서에서 이를 전기적인 신호로 변환시켜 기기의 메인 콘트롤러에 전송하고, 메인 콘트롤러는 이 전기적인 신호에 의해 내부 회로의 보호를 위한 동작 또는 외부 출력을 제어하도록 한다.Usually, these devices are shock sensors, which use sensors such as vibration sensors and acceleration sensors to determine whether they are impacted from the outside, and when an external shock is applied, the sensors convert it into an electrical signal, which is the main controller of the device. In turn, the main controller uses this electrical signal to control the operation or external output for protection of the internal circuitry.

이러한 충격감지 장치가 부착된 예의 대표적인 것이 자동차의 에어백 장치로서, 자동차의 추돌시 충격감지 센서가 충격력을 센싱하여 자동차의 ECU(Electrical Control Unit)에 전달하고, ECU에서 센싱된 충격력에 따라 에어백 장치의 작동 여부를 판단하는 것이다.An example of such an example in which the shock detection device is attached is an airbag device of a vehicle, and a shock detection sensor senses an impact force when the vehicle collides and transmits it to an ECU (Electric Control Unit) of the vehicle, and according to the impact force sensed by the ECU, It is to determine whether it works.

그러나, 이러한 종래 충격 감지 장치는 가속도 감지 센서 또는 진동 감지 센서 등 정밀한 센서를 사용하고 있어 고가(高價)이며, 센서의 제조과정 및 구조가 복잡하여 정밀 전자기기, 통신기기 및 측정기기 등 특정 기기에만 사용되어 그 적용범위가 매우 제한적이다.However, such a conventional shock sensing device is expensive because it uses a precise sensor such as an acceleration sensor or a vibration sensor, and the manufacturing process and structure of the sensor are complicated, so that only a specific device such as a precision electronic device, a communication device, and a measuring device is used. Used, the scope of application is very limited.

이에 본 발명은 충격에 취약한 전자기기 또는 통신기기 뿐만 아니라 충격을 감지할 필요한 장치에 널리 적용될 수 있도록 구조가 간단하고, 기기에 외부의 물리적인 충격이 가해졌는지를 쉽게 인지할 수 있는 충격감지 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention provides a shock sensing device that is simple in structure to be widely applied to an electronic device or a communication device that is vulnerable to shock as well as a device for sensing a shock, and easily recognizes whether an external physical shock is applied to the device. The purpose is to provide.

좀더 구체적으로 설명하면, 케이싱(10)은 육면체 형태로 형성하되 일측면을 개구시켜 개구된 일측면에 투명 윈도우(11)를 형성한다.In more detail, the casing 10 is formed in a hexahedral shape, but one side is opened to form a transparent window 11 on one side of the opened side.

투명 윈도우(11)는 투명 아크릴 판 또는 투명 필름막을 사용하고, 그 외 투명한 재질로 형성된 것이면 어떠한 것을 사용하더라도 무방하다.The transparent window 11 may be a transparent acrylic plate or a transparent film film, and may be any type as long as it is formed of another transparent material.

또한, 케이싱(10)의 외측면에는 서로 대향된 위치에 외부의 메인 콘트롤러(미도시)를 통해 전류가 인가되도록 하는 단자인 제1 및 제2 전극(12a,12b)을 형성한다.In addition, first and second electrodes 12a and 12b, which are terminals through which an electric current is applied through external main controllers (not shown), are formed on the outer surfaces of the casing 10.

도전성 재질로 된 금속 세선(13)은 케이싱의 제1 및 제2 전극(12a,12b)에 각각 일단이 접합되고 케이싱(10)의 내측으로 타단이 돌출 형성된 제1 및 제2세선(13a,13b)으로 구성된다.The thin metal wire 13 made of a conductive material has one end bonded to the first and second electrodes 12a and 12b of the casing, respectively, and the first and second fine wires 13a and 13b having the other end protruding into the casing 10. It is composed of

도전성 재질로 된 중량체(14)는 케이싱(10)의 내측으로 돌출된 제1 및 제2 세선(13a,13b)의 타단에 접합되어 케이싱의 어느 하나의 내측면과 접촉되지 않게 케이싱 내부에 위치된 중실(中實)형태의 금속볼(ball)이다.The weight body 14 made of a conductive material is bonded to the other ends of the first and second thin wires 13a and 13b protruding into the casing 10 and positioned inside the casing so as not to come into contact with any one inner surface of the casing. It is a solid metal ball.

여기서, 중량체로서 중실 형태의 중량을 가진 금속볼을 사용하는 것은 외부에서 충격이 가해지면 볼의 하중에 의해 금속볼이 상하로 진동하면서 진동하는 힘이 제1 및 제2 세선(13a,13b)과의 접합력 이상으로 발생되면 제1 및 제2 세선에서 금속볼이 떨어지도록 하기 위한 것이다.Here, the use of a metal ball having a solid weight as a weight body is the first and second fine wires (13a, 13b) that vibrates while the metal ball vibrates up and down by the load of the ball when the impact is applied from the outside If more than the bonding force with and to cause the metal ball to fall from the first and second thin wire.

또한, 중량체로서 중실 형태의 중량을 가진 볼 이외에 중량을 가지는 것이면 어떠한 형태인 것을 사용하더라도 무방하다.Moreover, as long as it has a weight other than the ball | bolt which has a solid weight as a weight body, what kind of thing may be used.

상술한 구성으로 된 본 발명에 따른 충격감지 장치의 충격 감지 동작을 도 2를 참조하여 설명한다.The shock detection operation of the shock detection device according to the present invention having the above-described configuration will be described with reference to FIG. 2.

도 3 는 본 발명에 따른 충격감지 장치를 충격을 감지하고자 하는 기기에 고정판(20)을 이용하여 고정시키고, 제1 및 제2 전극(21)에 전류를 인가하기 위한 리드 도선(21)을 접합시킨 상태를 도시한 것이다.Figure 3 is fixed to the shock sensing device according to the present invention using a fixed plate 20 to the device to detect the shock, and bonded the lead wire 21 for applying a current to the first and second electrodes 21 It is a state shown.

이와 같이 설치되는 본 발명에 따른 충격감지 장치는 중량체인 금속볼(14)이 제1 및 제2 세선(13a,13b)에서 떨어졌는지의 여부를 통해 외부에서 충격이 가해졌는지의 여부를 알 수 있게 된다.In the impact sensing device according to the present invention installed as described above, it is possible to know whether the impact is applied from the outside through whether the metal ball 14, which is the weight body, is dropped from the first and second thin wires 13a and 13b. .

즉, 외부에서 충격이 가해지면 중량을 가지는 금속볼(14)이 충격이 가해진 방향으로 상하로 진동하게 되고, 금속볼의 상하 진동하는 힘이 금속볼과 제1 및 제2세선(13a,13b)의 접합력 이상으로 작용하면 서로 떨어지게 되기 때문이다.That is, when an impact is applied from the outside, the metal ball 14 having the weight vibrates up and down in the direction in which the impact is applied, and the force of the metal ball vibrating up and down is the metal ball and the first and second fine wires 13a and 13b. This is because if the action of more than the bonding strength of each other will fall.

It is possible to electrically recognize that an impact has been applied.

또한, 금속볼(14)이 제1 및 제2 세선(13a,13b)에서 떨어지게 되면 케이싱의 투명 윈도우(11)를 통해 외부에서 육안으로 확인할 수 있어 기기에 충격이 가해졌음을 시각적으로 인지할 수 있게 된다.In addition, when the metal ball 14 is separated from the first and second thin wires (13a, 13b) can be visually confirmed from the outside through the transparent window 11 of the casing, it can be visually recognized that the impact was applied to the device Will be.

상기에서 상술한 바와 같이, 본 발명에 따른 충격 감지 장치는 센서를 이용하지 않고 금속볼이 제1 및 제2 세선에서 떨어지는 여부에 따라 충격이 가해졌음을 전기적으로 인지할 수 있을 뿐만 아니라 시각적으로 인지할 수 있게 되어 간단한 구조로서 충격을 감지할 수 있게 된다.As described above, the shock sensing device according to the present invention can visually recognize as well as electrically recognize that an impact is applied depending on whether the metal ball falls from the first and second thin wires without using a sensor. It is possible to detect the shock as a simple structure.

따라서, 제조과정이 간단하고 저가(低價)로 대량 생산할 있어 정밀 전자기기, 정밀 통신기기 및 정밀 측정기기 뿐만 아니라 충격을 감지하여 이에 따른 조치를 취해야 할 많은 장치에 적용될 수 있다.Therefore, the manufacturing process is simple and can be mass-produced at low cost, so that it can be applied not only to precision electronic devices, precision communication devices, and precision measuring devices, but also to many devices to detect shocks and take action accordingly.
