가이드관(4)은 실린더(1)의 일측 개방부분을 밀폐시키는 역할과 밸브시트 지지관(8)을 고정하는 역할을 하며, 원주벽 양측에는 축방향의 장공(5)이 형성되어 있고 이 가이드관(4)은 스크류(6)(7)에 의해 실린더(1) 및 밸브시트 지지관(8)과 결합되어 있다.The guide tube 4 serves to seal one open portion of the cylinder 1 and to fix the valve seat support tube 8. An axial long hole 5 is formed at both sides of the circumferential wall. The tube 4 is coupled to the cylinder 1 and the valve seat support tube 8 by screws 6, 7.
밸브시트 지지관(8)은 제4도와 같이 원통형으로 되어 있으며, 원주벽에는 수개의 유입공(9)이 형성되어 실린더(1)내로 주입된 에어가 유입공(9)을 통해 밸브시트 지지관(8)내에도 충진된다. 밸브시트 지지관(8)내에 설치된 밸브시트(10)와 밸브시트 지지관(8) 사이에는 볼트(11)와 너트(12)가 결합되어 있고 볼트(11)에는 스프링(13)이 결합되어 있다.The valve seat support tube 8 has a cylindrical shape as shown in FIG. 4, and several inlet holes 9 are formed in the circumferential wall so that the air injected into the cylinder 1 flows through the inlet hole 9 through the valve seat support tube. (8) It is filled in, too. A bolt 11 and a nut 12 are coupled between the valve seat 10 and the valve seat support tube 8 provided in the valve seat support tube 8, and a spring 13 is coupled to the bolt 11. .
따라서 밸브시트(10)는 스프링(13)의 힘에 의해 항상 전방(도면상 우측방향)으로 밀리는 힘을 받는다.Therefore, the valve seat 10 is always pushed forward (rightward in the drawing) by the force of the spring 13.
가이드관(4)내에 설치된 슬라이딩관(14)은 제3도와 같이 양측이 개방된 파이프 형상으로 되어 있고 후방에는 수개의 절결홈부(15)가 형성되어 있으며, 전방에는 슬라이딩관을 가이드관(4)내에 조립하기 위한 체결공(16)과 슬라이딩관의 이동제어를 위한 플런저 삽입공(17)이 형성되어 있다.The sliding tube 14 installed in the guide tube 4 has a pipe shape in which both sides are open as shown in FIG. 3, and several notch grooves 15 are formed at the rear thereof, and the sliding tube 14 is formed at the front of the guide tube 4. A fastening hole 16 for assembling therein and a plunger insertion hole 17 for movement control of the sliding tube are formed.
또한 슬라이딩관(14)에 형성된 체결공(16)과 가이드관(4)에 형성된 장공(5)사이에는 핀(18)이 결합되어 슬라이딩관(14)은 장공(5)의 길이범위 내에서 가이드관(4)을 따라 슬라이딩을 할 수있다.In addition, the pin 18 is coupled between the fastening hole 16 formed in the sliding tube 14 and the long hole 5 formed in the guide tube 4 so that the sliding tube 14 guides within the length range of the long hole 5. It can slide along the tube (4).
가이드관(4)의 선단부에는 카버(19)가 고정핀(20)에 의해 고정되어 있으며, 슬라딩관완(14)의 선단과 카버(19)사이에는 스프링(21)이 설치되어 있다.Carbures 19 are fixed to the distal end of the guide tube 4 by a fixing pin 20, and a spring 21 is provided between the distal end of the sliding tube arm 14 and the carver 19.
이 스프링(21)은 전술한 볼트(11)의 바깥둘레에 설치된 스프링(13)보다 큰힘을 가지며, 따라서 슬라이딩관(14)은 항상 후방으로 밀리는 힘을 받는다.This spring 21 has a greater force than the spring 13 provided on the outer circumference of the bolt 11 described above, so that the sliding tube 14 is always pushed backward.
그리고 가이드관(4)의 일측 원주벽에는 솔레노이드 밸브(22)가 설치되어 제2도와 같이 솔레노이드 밸브의 플런저(23)가 슬라이딩관(14)에 형성된 플런저 삽입공(17)에 끼워진 상태(비작동시)에서는 슬라이딩관(14)의 이동이 구속된다.The solenoid valve 22 is installed on one side circumferential wall of the guide tube 4 so that the plunger 23 of the solenoid valve is fitted into the plunger insertion hole 17 formed in the sliding tube 14 as shown in FIG. At the time), the movement of the sliding tube 14 is restricted.
또한 솔레노이드 밸브(22)는 제5도와 같이 차량의 임의의 위치에 설치된 계전기(24)와 전기적으로 연결되어 있으며, 계전기(24)의 근접한 위치에는 작동판(26)이 스프링(28)에 의해 탄력적으로 설치되어 있다.In addition, the solenoid valve 22 is electrically connected to the relay 24 installed at any position of the vehicle as shown in FIG. 5, and the operating plate 26 is elastically provided by the spring 28 at a position adjacent to the relay 24. It is installed.
따라서 차량에 축방향의 힘이 가해지면 작동판(26)이 관성에 의해 진동함과 동시에 작동판(26)의 접점(27)과 계진기(24)의 접점(25)이 접속되어 솔레노이드 밸브(22)가 작동하게 된다.Therefore, when an axial force is applied to the vehicle, the operating plate 26 vibrates by inertia, and at the same time, the contact 27 of the operating plate 26 and the contact 25 of the gauge 24 are connected to the solenoid valve 22. ) Will work.
도면중 설명되지 않은 부호 29는 작동판(26)에 연결된 스프링(28)의 장력조절을 위한 조절볼트, 30은 건전지, 31은 가이드관(4)과 에어백(도시는 생략함)사이에 연결된 에어호스이다.Reference numeral 29, which is not described in the drawing, is an adjustment bolt for tension adjustment of the spring 28 connected to the operation plate 26, 30 is a battery, 31 is air connected between the guide tube 4 and the airbag (not shown). Hose.
이와같이 구성된 본 고안의 작용효과를 설명한다.The effect of the present invention configured as described above will be described.
먼저 본 고안 장치는 실린더(1) 내에 에어를 기압(약 3∼5기압 정도)으로 충진시킨 상태에서 실린더(1)를 차량의 적당위치에 부착하고 가이드관(4)과 에어백 사이에 에어호스(31)를 연결한 상태로 사용하게 되며, 에어백은 절첩하여 탑승자가 착용한 안전벨트에 결합하는 것이 바람직하다.First, the device of the present invention attaches the cylinder 1 to an appropriate position of the vehicle while filling the cylinder 1 with air pressure (about 3 to 5 atmospheres), and between the guide tube 4 and the air bag, 31) is used in a connected state, it is preferable that the airbag is folded and coupled to the seat belt worn by the occupant.
또한 작동판(26)은 차량의 진행방향으로 충격이 가해질때 진동할 수 있도록 적당한 위치에 설치될 수도 있고 차량의 측면에서 충격이 가해질때 진동할 수 있는 위치에 설치될 수도 있다.In addition, the operation plate 26 may be installed at a suitable position to vibrate when an impact is applied in the traveling direction of the vehicle, or may be installed at a position capable of vibrating when an impact is applied at the side of the vehicle.
이렇게 본고안 장치를 차량에 설치하여 차량이 정상운행 하는 동안에는 차량에 일정 한계이상의 충격이 가해지지 않도록 작동판(26)의 접점(27)과 계전기(24)의 접점(25)은 떨어져 있게 되며, 솔레노이드 밸브(22)는 오프되어 있게 된다.In this way, the device is installed in the vehicle so that the contact 27 of the operating plate 26 and the contact 25 of the relay 24 are separated from each other during the normal operation of the vehicle so that a shock beyond the predetermined limit is not applied to the vehicle. The solenoid valve 22 is turned off.
따라서 솔레노이드 밸브(22)의 플런저(23)는 슬라이딩관(14)의 플런저 삽입공(17)으로 끼워져 슬라이딩관을 구속하게 되며, 슬라이딩관(14)과 카버(19)사이에 설치된 스프링(21)은 압축되어 있고, 밸브시트 지지관(8)내에 설치된 밸브시트(10)는 스프링(13)의 힘에 의해 가이드관(4) 방향으로 전진하여 가이드관(4)의 입구부를 폐쇄하고 있다.Therefore, the plunger 23 of the solenoid valve 22 is inserted into the plunger insertion hole 17 of the sliding tube 14 to restrain the sliding tube, and the spring 21 installed between the sliding tube 14 and the carver 19. Is compressed, and the valve seat 10 provided in the valve seat support tube 8 is advanced in the direction of the guide tube 4 by the force of the spring 13 and closes the inlet of the guide tube 4.
그러나 제1도(a) 및 제2도와 같은 상태에서 차량에 축방향의 충격이 가해지면 제5도에 일점쇄선으로 도시한 바와같이 작동판(26)이 진동함과 동시에 작동판(26)의 접점(27)과 계전기(24)의 접점(25)이 접속되어 솔레노이드 밸브(22)가 작동하게 되고 이에따라 플런저(23)가 당겨지면서 슬라이딩관(14)의 플런저 삽입공(17)에 빠져나오게 된다.However, when the axial shock is applied to the vehicle in the state shown in FIGS. 1A and 2D, the operating plate 26 vibrates and the operating plate 26 is vibrated at the same time as shown in FIG. The contact 27 and the contact 25 of the relay 24 are connected so that the solenoid valve 22 is actuated, and accordingly the plunger 23 is pulled out of the plunger insertion hole 17 of the sliding tube 14. .
따라서 슬라이딩관(14)은 플런저(23)의 구속상태에서 해제되며, 슬라이딩관(14)이 해제되면 밸브시트 지지관(8)과 밸브시트(10) 사이에 설치된 스프링(13)의 힘보다 슬라이딩관(14)과 카버(19)사이에 설치된 스프링(21)의 힘이 크기 때문에 슬라이딩관(14)은 스프링의 힘에 의해 후방으로 밀려나게 된다.Therefore, the sliding tube 14 is released under the restraint state of the plunger 23, and when the sliding tube 14 is released, the sliding tube 14 slides more than the force of the spring 13 installed between the valve seat support tube 8 and the valve seat 10. Since the force of the spring 21 provided between the tube 14 and the carver 19 is large, the sliding tube 14 is pushed back by the force of the spring.
또 슬라이딩관(14)이 후방(밸브시크트 방향)으로 밀려나면 제1도(b)와 같이 가이드관(4)의 내부에 위치하여 있던 슬라이딩관(14)의 절결홈부(15)가 가이드관(4)의 바깥측으로 노출되므로 실린더(1)와 밸브시트 지지관(8)내에 충진된 고압의 에어는 슬라이딩관(14)의 절결홈부(15)를 통해 슬라이딩관(14)내로 유입된 후 가이드관(4)과 에어호스(31)를 거쳐 에어백에 공급되어 에어백을 풍선처럼 부풀게 한다.When the sliding tube 14 is pushed backward (valve sheet direction), the notch groove 15 of the sliding tube 14 located inside the guide tube 4 as shown in FIG. Since the high pressure air filled in the cylinder 1 and the valve seat support tube 8 is exposed to the outside of the (4), the air flows into the sliding tube 14 through the cutout groove 15 of the sliding tube 14 and then guides. It is supplied to the airbag via the pipe 4 and the air hose 31 to inflate the airbag like a balloon.
따라서 차량의 충돌시 탑승자의 신체부위가 핸들이나 전면유리 또는 의자 등받이등에 부딪혀 부상하는 사고를 막을 수 있게 되며, 상기한 에어의 공급은 순간적인 작동에 의해 이루어지므로 에어백도 순간적으로 부풀어 인체의 충격을 방지해 준다.Therefore, it is possible to prevent the accident of the body part of the occupant hit the steering wheel, the windshield or the back of the chair during the collision of the vehicle, and the air supply is instantaneously inflated because the air supply is made by instant operation. Prevents.
이렇게 차량의 충돌로 인해 본고안 장치가 작동된 후에는 실린더(1)에 설치된 에어캡(2)을 열고 다시 에어를 충진한후 재사용을 할 수 있다.After the device is operated due to the collision of the vehicle, the air cap 2 installed in the cylinder 1 can be opened, and the air can be refilled and reused.
이상에서와 같이 본 고안은 차량내의 어느 위치에서 부착시킬 수 있으므로 설치가 간편하고 그 구조가 매우 간단하여 저렴한 가격에 공급할 수 있는 잇점이 있다.As described above, the present invention can be attached at any position in the vehicle, so it is easy to install and its structure is very simple, so it can be supplied at a low price.
