자동차의 완충장치{shock absorber of automobile}Shock Absorber of Automobile

본 고안은 자동차의 완충장치에 관한 것으로, 더욱 상세하게는 차량의 운행중에 발생될 수 있는 사고에 의해 차체의 전후면으로부터 가해지는 충격이 실내로 전달되는 것을 완화하여 탑승객을 보호할 수 있도록 한 자동차의 완충장치에 관한 것이다.The present invention relates to a shock absorber of a vehicle, and more particularly, a vehicle that can protect passengers by mitigating the shock transmitted from the front and rear of the vehicle body to an interior due to an accident that may occur during the operation of the vehicle. It relates to a shock absorber of.

일반적으로 자동차에는 차량의 충돌 사고시에 탑승자를 보호하기 위하여 에어백, 범퍼, 임팩트 빔과 같은 각종 충격완화장치 및 안전장치를 구비하고 있는데, 이 중에 에어백은 운전자나 조수석에 탑승하고 있는 승객만 보호할 뿐 뒷좌석에 탑승한 승객은 보호할 수 없으며, 사소한 충격에도 오작동하여 오히려 운전자의 안전운행을 방해하는 문제점이 있었으며, 범퍼는 구조적으로 실내로 전달되는 충격을 크게 흡수하지 못하므로, 승객을 안전하게 보호하지 못하는 문제점이 있었고, 임팩트 빔은 차량으로 측면으로 가해지는 충격에 대해 탑승객을 보호하기 위하여 도어의 내측을 전후로 가로지르도록 설치한 것으로, 전면충돌과 후면충돌에 대해서는 완충효과를 갖지 못하였다.In general, automobiles are equipped with various shock absorbers and safety devices such as airbags, bumpers and impact beams to protect occupants in the event of a vehicle crash. Among these, airbags only protect the driver or passenger in the passenger seat. Passengers in the rear seats could not be protected, and there was a problem of malfunctioning even in minor impacts, which hindered the driver's safe operation.Bumpers cannot structurally absorb the shocks transmitted to the room, which prevents passengers from being protected There was a problem, and the impact beam was installed to cross the inside of the door back and forth in order to protect the passengers against the side impact from the vehicle, and had no buffering effect against the front collision and the rear collision.

본 고안은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 충돌 사고시에 차량의 외부로부터 실내로 전달되는 충격을 흡수하여 탑승객을 보호하는 동시에 충격에너지의 흡수율을 높일 수 있는 자동차의 완충장치를 제공함에 있다.The present invention has been made to solve the above problems, the object of the invention is to absorb the shock transmitted to the interior from the outside of the vehicle in the event of a crash to protect the passengers and at the same time to increase the absorption rate of the impact energy of the vehicle In providing.

이러한 본 고안의 목적을 달성하기 위하여 탑승실이 형성된 부상차체부를 전면차체부와 후면차체부 사이에서 복수의 완충기구를 매개로 설치하여 자동차의 완충장치가 제공된다.In order to achieve the object of the present invention there is provided a shock absorber of the vehicle by installing a plurality of shock absorbing mechanism between the front vehicle body portion and the rear vehicle body portion is formed in the cabin.

이하 본 고안에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도3에 도시된 바와 같이 자동차가 전면충돌이나 후면충돌을 일으키게 되면, 자동차의 전면차체부(40) 또는 후면차체부(50)가 각각 전후방향으로 밀리면서 그 충격이 완충기구(70)를 통해 부상차체부(60)로 전달되는데, 이때 완충기구(70)가 압축되면서 실린더튜브(72)의 내압이 급격하게 상승되고, 내압이 제한압력이상으로 상승되면, 배출포트(71)를 폐쇄하고 있던 압력제한밸브(V)가 개방되면서 실린더튜브(72) 내의 압축가스(G)가 외부로 배출된다.1 to 3, when the vehicle causes a front collision or a rear collision, the front vehicle body portion 40 or the rear vehicle body portion 50 of the vehicle is pushed in the front and rear directions, respectively, the shock absorbing mechanism When the internal pressure of the cylinder tube 72 is rapidly increased while the shock absorbing mechanism 70 is compressed, and the internal pressure is raised above the limit pressure, the discharge port 71 is transmitted to the floating vehicle body 60 through 70. The pressure limiting valve (V), which has been closed, is opened and the compressed gas (G) in the cylinder tube (72) is discharged to the outside.

즉, 전면차체부(40)와 후면차체부(50)에 각각 연결되어 있는 완충기구(70)의 플런저(74)가 이들 전면차체부(40)와 후면차체부(50)에 의해 실린더튜브(72)의 내측으로 밀리면서 압축되어 완충기구(70)가 신축하게 되고, 승객이 위치되어 있는 부상차체부(60)는 전면차체부(40)와 후면차체부(50)로 전달되는 충격을 직접적으로는 받지 않고 완충기구(70)에 의해 완화된 상태에서 받게 된다.That is, the plunger 74 of the shock absorbing mechanism 70 connected to the front body 40 and the rear body 50, respectively, by the front body 40 and the rear body 50, the cylinder tube ( 72 is compressed while being pushed into the inside of the shock absorbing mechanism 70 is stretched, the passenger vehicle body portion 60 where the passenger is located directly to the impact transmitted to the front body portion 40 and the rear body portion 50. It is received in a relaxed state by the shock absorbing mechanism 70 without receiving.

이때 실린터튜브(72)와 플런저(74) 사이에서 반발하고 있던 스프링(73)이 압축되면서 충격을 흡수하게 되고, 전면차체부(40)와 후면차체부(50)로 전달된 충격에너지는 실린더튜브(72)에 충전되어 있던 압축가스(G)를 압축하는 에너지로 변환되는 동시에 압력제한밸브(V)가 열리면서 외부로 배출되고, 압축가스(G)가 외부로 방출되면서 실린더튜브(72) 내의 압력이 제한압력미만으로 떨어지게 되면, 다시 압력제한밸브(V)가 닫히면서 실린더튜브(72) 내에는 압축가스(G)가 잔류하게 된다.At this time, the spring 73 repulsed between the cylinder tube 72 and the plunger 74 is compressed to absorb the shock, and the impact energy transmitted to the front body portion 40 and the rear body portion 50 is a cylinder. The compressed gas G charged in the tube 72 is converted into energy to be compressed, and at the same time, the pressure limiting valve V is opened to be discharged to the outside, and the compressed gas G is discharged to the outside, so that When the pressure drops below the limit pressure, the pressure limiting valve V is closed again, and the compressed gas G remains in the cylinder tube 72.

이와 같이 압력제한밸브(V)가 순간적으로 열리고 닫히는 ON/OFF를 반복하면서 짧은 거리에서의 충격을 보다 효과적으로 완화시키는 작용을 하게 된다.As described above, the pressure limiting valve V is momentarily opened and closed while repeating ON / OFF to more effectively alleviate the shock at a short distance.

한편, 자동차가 충격을 받게 되면, 상기 전면차체부(40)와 후면차체부(50)의 전후면에 각각 설치되어 있는 충격감지센서(S1)(S2)에 의해 검출되어 전자제어유닛(ECU)의 입력포트로 입력되고, 이 전자제어유닛(ECU)은 출력포트를 통해 고전압발생부(120)에 점화신호가 출력되어 점화부(100)(102)가 발화되고, 이 점화부(100)(102)의 발화에 의해 작약(94)(96)이 폭발되면서 자동차의 전면차체부(40)와 후면차체부(50)에 각각 설치되어 있는 에어백(90)(92)이 부풀게 된다.On the other hand, when the car is subjected to an impact, it is detected by the shock sensor (S1) (S2) provided on the front and rear surfaces of the front body portion 40 and the rear body 50, respectively, the electronic control unit (ECU) The electronic control unit (ECU) outputs an ignition signal to the high voltage generator 120 through an output port so that the ignition unit 100 and 102 are ignited, and the ignition unit 100 ( As the charges 94 and 96 are exploded by the ignition of the 102, the airbags 90 and 92 respectively installed in the front body 40 and the rear body 50 of the vehicle are inflated.

이때 에어백(90)(92)이 부풀면서 충돌물체와의 충격을 완화하게 되고, 결국 자동차의 전면차체부(40)와 후면차체부(50)로 전달되는 충격을 완화하는 동시에 승객이 위치되어 있는 부상차체부(60)로 전달되는 충격을 완화하는 작용을 하게 된다.At this time, the airbags 90 and 92 are inflated to alleviate the impact with the collision object, and eventually the shock is transmitted to the front body portion 40 and the rear body portion 50 of the vehicle. It acts to mitigate the shock delivered to the floating vehicle body 60.

이상에서 설명한 바와 같은 본 고안은 주행중에 발생할 수 있는 자동차의 전면충돌이나 후면충돌시에 승객이 위치되어 있는 부상차체로 전달되는 충격을 완충기구에 의해 완화할 수 있도록 구성되어 있기 때문에 작은 충격으로부터는 승객을 안전하게 보호하고, 매우 큰 충격으로부터는 승객의 부상 정도를 낮출 수 있는 효과가 있다.As described above, the present invention is designed to mitigate the shock transmitted to the injured vehicle in which the passenger is located in the front collision or the rear collision of the vehicle, which may occur during driving, by the shock absorbing mechanism. There is an effect to protect the passengers safely, and to reduce the injuries of the passengers from a very large impact.
