본 고안은 공기에 의한 범퍼완충구조에 관한 것이다.The present invention relates to a bumper buffer structure by air.
종래의 범퍼완충구조는 제1도에 도시한 바와 같이 범퍼(a)와 임팩트 피스톤(b)사이에 우레탄폼(c)을 개재하여 범퍼(a)에 충격이 가해지면 범퍼(a)와 임팩트 피스톤(b) 사이의 우레탄 폼(c)이 충격을 흡수하여 완충효과를 얻게 되나 상기와 같은 우레탄 폼(c)의 완충재는 완충효과가 크지 않을 뿐만 아니라 한 번 충격을 받은 후에는 원상태로의 복원이 거의 이루어지지 않으므로 한 번 충격을 받은 범퍼(a)는 재사용을 하지 못하고 전면 교체를 하여야 하므로 경제적인 손실이 커지지 않게 폐단이 있는 것이다.In the conventional bumper buffer structure, as shown in FIG. 1, the bumper a and the impact piston are applied when the bumper a is impacted through the urethane foam c between the bumper a and the impact piston b. The urethane foam (c) between (b) absorbs the shock and obtains a buffering effect. However, the cushioning material of the urethane foam (c) is not only large in buffering effect but also restored to its original state after being impacted once. Since the bumper (a) is not shocked once, it is not reused and must be replaced in the front, so that the economical loss does not increase.
본 고안의 목적은 상기와 같은 점을 감안하여 한 번 충격을 받은 후에 복원이 가능하고 범퍼에 가해지는 충격을 흡수하여 완충작용을 더욱 상승시키는데 목적이 있는 것이다.The object of the present invention is to restore after being impacted once in view of the above point and to absorb the shock applied to the bumper is to further increase the cushioning action.
상기의 목적은, 범퍼의 후부의 임팩트 피스톤 전방에 드레인 홀이 형성되고 내부에 복원스프링이 내설된 에어탱크를 설치하므로서 달성된다.The above object is achieved by providing an air tank in which a drain hole is formed in front of the impact piston at the rear side of the bumper and in which a restoring spring is embedded.
이하 첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.Hereinafter will be described in more detail based on the accompanying drawings.
범퍼(1) 후부 임팩트 피스톤(4) 전방에 복원스프링(5)으로 탄지되는 에어탱크(2)를 설치하고 에어탱크(2)의 일측에 드레인 홀(3)을 천공시켜서 된 것이다.The air tank 2 carried by the restoring spring 5 in front of the bumper 1 rear impact piston 4 is provided, and the drain hole 3 is drilled in one side of the air tank 2.
이와 같이 된 본 고안은,The present devised in this way,
범퍼(1)에 충격이 가해지게 되면, 범퍼(1) 후부의 에이탱크(2)에 충격이 전달되게 되는데 에어탱크(2)는 임팩트 피스톤(4)에 복원스프링(5)으로 탄지되고 에어탱크(2)의 내부에는 공기가 있으므로 에어탱크(2)에 충격이 전달되면 에어탱크(2)가 임팩트 피스톤(4)쪽으로 압축되게 되고 에어탱크(2)가 압축되면서 에어탱크(2)내의 공기가 드레인 홀(3)로 빠져나가고 또한 복원스프링(5)의 탄발력에 의해 에어탱크(2)에 전달된 충격이 완충되게 된다.When an impact is applied to the bumper 1, an impact is transmitted to the A tank 2 at the rear of the bumper 1. The air tank 2 is supported by the restoring spring 5 on the impact piston 4 and the air tank. Since there is air in the inside of (2), when an impact is transmitted to the air tank (2), the air tank (2) is compressed toward the impact piston (4) and the air tank (2) is compressed, so that the air in the air tank (2) The shock transmitted to the air tank 2 by the elastic force of the restoring spring 5 exits to the drain hole 3 and becomes cushioned.
이렇게 에어탱크(2)에 전달된 충격은 완충되게 되고 충격을 완충한 에어탱크(2)는 복원스프링(5)의 복원력으로 에어탱크(2)가 원위치 되게 된다.The shock transmitted to the air tank 2 is buffered and the air tank 2 buffered the shock is the air tank (2) to the original position by the restoring force of the restoring spring (5).
에어탱크(2)는 복원스프링(5)의 복원력으로 복원되면서 에어탱크(2)의 일측에 천공된 드레인 홀(3)로 공기가 다시 유입되게 되므로 에어탱크(2) 내에는 공기가 다시 차있게 되는 것이다.The air tank (2) is restored to the restoring force of the restoring spring (5) and the air is introduced again into the drain hole (3) perforated on one side of the air tank (2), so that the air is filled again in the air tank (2) Will be.
상기와 같이 에어탱크(2)가 복원스프링(5)에 의해 복원된 상태에서 다시 범퍼(1)에 충격이 가해지면 에어탱크(2)내의 공기와 복원스프링(5)의 탄발력으로 범퍼(1)에 가해진 충격이 완충되게 되는 것이다.When the shock is applied to the bumper 1 again in the state in which the air tank 2 is restored by the restoring spring 5 as described above, the bumper 1 may be caused by the elasticity of the air in the air tank 2 and the restoring spring 5. The shock applied to) will be buffered.
이와 같이 본 고안은 범퍼(1) 후부의 임팩트 피스톤(4) 전방에 에어탱크(2)를 복원스프링(5)으로 탄지되게 설치하므로서 범퍼(1)에 충격이 가해지면 에어탱크(2) 내부의 공기와 복원스프링(5)에 의해 범퍼(1)의 충격을 완충시키므로서 에어탱크(2)내의 공기와 복원스프링(5)에 의해 충격이 완충되므로 완충효과를 증대시킬 뿐만 아니라 범퍼(1)에 충격이 가해진 다음에는 에어탱크(2)내의 복원스프링(5)에 의해 에어탱크(2)가 다시 복원되므로서 범퍼(1)를 재사용할 수 있으므로 경제적으로 효율적인 등의 효과가 있는 유용한 고안인 것이다.As such, the present invention installs the air tank 2 in front of the impact piston 4 at the rear of the bumper 1 with a restoring spring 5 so that when the bumper 1 is impacted, the inside of the air tank 2 By cushioning the shock of the bumper 1 by the air and the restoring spring 5, the shock is cushioned by the air and the restoring spring 5 in the air tank 2, thereby increasing the buffering effect and increasing the bumper 1. After the impact is applied, the bumper 1 can be reused while the air tank 2 is restored by the restoring spring 5 in the air tank 2, which is a useful design having an effect such as economical efficiency and the like.
