Description

이중 충격 흡수 장치{APPARATUS FOR BUFFERING THE DOUBLE IMPACT}Dual Shock Absorber {APPARATUS FOR BUFFERING THE DOUBLE IMPACT}

본 발명은 충격 흡수 장치에 관한 것으로, 더욱 상세하게는 고무의 탄성과 공기의 압축성을 이용하여 충격 물체의 충격시 순간 충격량을 최소화시키면서 충격 흡수력을 최대화시킬 수 있도록 하는 2중 충격 흡수 장치에 관한 것이다.The present invention relates to a shock absorbing device, and more particularly, to a double shock absorbing device that can maximize the shock absorbing power while minimizing the instantaneous impact amount upon impact of the impact object by using the elasticity of the rubber and compressibility of the air. .

일반적으로 무게를 가지는 물체가 어떤 높이에서 자유낙하 하여 충격을 받을 경우 바닥에 닿는 순간 충격량을 최대가 된다.In general, when an object with weight falls freely at a certain height and receives an impact, the maximum amount of impact is reached the moment it reaches the floor.

그래서 충격에 약한 고정밀도의 부품이나 장치 등은 운반시사용자의 부주의에 의해 부품이나 장치가 떨어져 충격을 받아 파손되는 것을 방지하도록 충격 방지 장치의 사용이 필수적이다.Therefore, the use of an impact prevention device is essential for high precision parts or devices that are not susceptible to impact and prevent the parts or device from falling off and being damaged due to carelessness of the user during transportation.

종래의 충격 방지 장치는 단순히 고무나 탄성체가 일체로 형성되어 부품을 운반하는 케이스 등의 저면에 부착되었다.Conventional anti-shock devices are simply attached to the bottom of a case or the like, in which a rubber or an elastic body is integrally formed to carry parts.

그러나 이러한 종래의 충격 방지 장치는 단순히 고무나 탄성체 자체의 탄발력을 이용하여 충격을 흡수하기 때문에 충격 흡수력이 약한 문제점이 있다.However, such a conventional anti-shock device has a problem in that the shock absorption force is weak because it absorbs the shock simply by using the elasticity of the rubber or the elastic body itself.

따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로, 고무의 탄력과 공기의 압축성을 이용하여 충격 물체의 충격시 순간 충격량을 최소화시키면서 충격 흡수력을 최대화할 수 있는 2중 충격 흡수 장치를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above problems, and provides a double shock absorbing device that can maximize the shock absorbing power while minimizing the instantaneous impact when the impact object impacts by using the elasticity of the rubber and the compressibility of the air. It is.

이하, 본 발명에 의한 2중 충격 흡수 장치의 구성을 도 1을 참조하여 상세하게 설명하기로 한다.Hereinafter, the configuration of the double shock absorber according to the present invention will be described in detail with reference to FIG.

도 1은 본 발명에 따른 2중 충격 흡수 장치의 구성을 나타낸 사시도이다.1 is a perspective view showing the configuration of a double shock absorbing device according to the present invention.

도 1을 참조하면, 본 발명에 따른 2중 충격 흡수 장치(100)는 본체(110)와, 지지부(120)와, 공기량 조절장치(130)와, 공기 밀폐장치(140)로 구성된다.Referring to FIG. 1, the double shock absorbing device 100 according to the present invention includes a main body 110, a support 120, an air amount adjusting device 130, and an air sealing device 140.

본체(110)는 내부에 공기의 충진이 가능한 반구(돔) 형태를 가지며, 탄성 재질(고무, 실리콘 등)로 형성된다. 여기에서 본체(110)는 반구 형태로 형성되는 것이 바람직하며, 그 필요에 따라 단면 형태를 사각, 삼각, 마름모 등으로 얼마든지 변경 가능하다.The main body 110 has a hemisphere (dome) shape that can be filled with air therein, and is formed of an elastic material (rubber, silicone, etc.). Here, the main body 110 is preferably formed in a hemispherical shape, and the cross-sectional shape can be changed as many times as square, triangular, rhombus, etc. as necessary.

지지부(120)는 본체(110)의 외주연에서 외측으로 연장 형성되고, 지지부(120)에는 본체(110)가 부착되는 받침대(1)와 본체(110)를 볼트 또는 접착제(도시 생략)에 의해 고정할 수 있는 볼트홀(121) 또는 접착면이 형성된다.The support 120 is formed to extend outward from the outer periphery of the main body 110, the support 120 is a pedestal 1 and the main body 110 to which the main body 110 is attached by bolts or adhesives (not shown) A bolt hole 121 or an adhesive surface that can be fixed is formed.

공기량 조절장치(130)는 본체(110)의 내측 중심 상단부에서 하측으로 연장형성되고, 공기 밀폐장치(140)는 공기량 조절장치(130)의 상단부에 외측으로 형성된다. 여기에서 상기 받침대(1)에는 공기량 조절장치(130)가 상하로 이동 가능하도록 공기량 조절장치(130)의 최대 지름보다 크고 공기 밀폐장치(140)의 지름보다는 작은 홀(2)이 형성된다. 여기에서 또한 본체(110)와 지지부(120)와 공기량 조절장치(130) 및 공기 밀폐장치(140)는 모두 동일 재질로 일체 성형되는 것이 바람직하다.The air amount adjusting device 130 extends downward from the inner center upper end of the main body 110, and the air sealing device 140 is formed outward at the upper end of the air amount adjusting device 130. Here, the pedestal 1 is formed with a hole 2 larger than the maximum diameter of the air amount adjusting device 130 and smaller than the diameter of the air sealing device 140 so that the air amount adjusting device 130 can move up and down. Here, the main body 110, the support 120, the air amount regulating device 130, and the air sealing device 140 are all integrally formed of the same material.

이하 본 발명에 따른 2중 충격 흡수 장치의 작용을 도 2를 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, the operation of the double shock absorber according to the present invention will be described in detail with reference to FIG. 2.

도 2는 본 발명에 따른 2중 충격 흡수 장치의 충격 흡수 과정을 단계적으로 나타낸 설명도이다.Figure 2 is an explanatory diagram showing the shock absorption process of the dual shock absorber according to the present invention step by step.

도 2를 참조하면, 부품 또는 장치가 내장되고, 저부에 2중 충격 흡수 장치(100)가 부착된 케이스(1)가 어떤 높이에서 자유 낙하로 떨어져 바닥에 닿아 충격이 전달되는 순간 2중 충격 흡수 장치(100)의 재질에 따른 고유 탄성에 의해 1차 최대 충격이 흡수되면서 본체(110)가 압축된다.Referring to FIG. 2, a case (1) having a component or device embedded therein and having a double shock absorbing device (100) attached to a bottom thereof falls freely at a certain height and touches the floor to deliver a double shock absorbing moment. The main body 110 is compressed while the primary maximum shock is absorbed by the inherent elasticity of the material of the apparatus 100.

본체(110)가 압축되면 케이스(1)에 형성된 홀(2)의 하방향으로 공기량 조절장치(130)가 이동되고, 이와 동시에 본체(110) 내부에 충진된 공기는 케이스(1)에 형성된 홀(2)을 통해 외부로 빠진다. 이를 보다 자세하게 설명하면 본체(110)는 자유 상태에서 케이스(1)의 홀(2)과 공기량 조절장치(130) 사이의 틈새가 최대로 되어 있는 상태에서 충격이 가해져 본체(110)가 압축을 시작하여 공기량 조절장치(130)가 하방향으로 이동함에 따라 공기가 통과할 수 있는 면적은 점점 좁아진다. 즉, 고무가 압축을 받는 순간은 순순하게 본체(110)의 탄성력만 작용하나 이와 동시에 본체(110)가 압축을 시작하며 공기가 유출되면 본체(110) 내부의 공기 압력이 상승하고, 이 힘, 즉 공기 압력이 충격 전달 시간을 지연시키면서 완충 효과를 높이게 된다.When the main body 110 is compressed, the air volume control device 130 moves downward of the hole 2 formed in the case 1, and at the same time, the air filled in the main body 110 is a hole formed in the case 1. Fall out through (2). In more detail, the main body 110 is impacted in a state where the gap between the hole 2 of the case 1 and the air volume control device 130 is maximized in a free state, and the main body 110 starts to compress. As the air volume control device 130 moves downward, the area through which air can pass is gradually narrowed. In other words, when the rubber is compressed, only the elastic force of the main body 110 acts in order, but at the same time, the main body 110 starts compressing and when the air is leaked, the air pressure inside the main body 110 increases, and this force, That is, the air pressure increases the shock absorbing effect while delaying the shock delivery time.

그러다가 본체(110)의 공기량 조절장치(130)에 형성된 공기 밀폐장치(140)가 홀(2)과 접촉되면 공기의 유출구가 밀폐되므로 본체(110) 내부는 압축 공기가 잔존하고, 이 압축공기는 1차 충격이후 발생되는 2차, 3차 충격을 완충시켜준다. 그리고 본체(110)로 가해지던 충격이 해소되면 본체(110)의 형상은 자체 복원력에 의해 다시 원 상태로 복원되며, 본체(110)의 복원에 따라 공기량 조절장치(130)도 다시 상방향으로 상승된다.Then, when the air sealing device 140 formed in the air volume control device 130 of the main body 110 contacts the hole 2, the air outlet is sealed, so the compressed air remains inside the main body 110. It cushions the 2nd and 3rd shocks generated after the 1st shock. And when the impact applied to the main body 110 is resolved, the shape of the main body 110 is restored to its original state by the self restoring force, and according to the restoration of the main body 110, the air amount adjusting device 130 also rises upward again. do.

따라서 본 발명에 따른 2중 충격 흡수 장치는 탄발력과 공기 압축력을 이용하여 충격을 흡수하도록 함으로써 효과적으로 충격을 흡수할 수 있다.Therefore, the double shock absorbing device according to the present invention can effectively absorb the shock by absorbing the shock using the elasticity and the air compression force.

또한 이러한 본 발명을 이용하여 중량물의 방진장치로도 활용이 가능하고, 본 발명을 수십~수백개 조합하여 공기 매트리스 등과 같은 안전장치로도 활용할 수 있으며, 본 발명의 원리를 이용하여 특수 충격 흡수체 설계 및 생활 편의 장치 등에 적용이 가능하다.In addition, the present invention can be utilized as a dustproof device of heavy weight, and can be utilized as a safety device such as an air mattress by combining the present invention with tens to hundreds, and design a special shock absorber using the principles of the present invention. And life convenience devices.

이상에서 설명한 바와 같이 본 발명에 따른 2중 충격 흡수 장치에 의하면, 고무의 탄력과 공기의 압축성을 이용하여 충격 물체의 충격시 순간 충격량을 최소화시키면서 충격 흡수력을 최대화시킬 수 있다.As described above, according to the dual shock absorbing apparatus according to the present invention, the shock absorbing power can be maximized while minimizing the instantaneous impact amount upon impact of the impact object by using the elasticity of the rubber and the compressibility of the air.
