본 발명은 자동차 후드용 충격 감쇄장치에 관한 것으로서, 더욱 상세히는 후드 충격 감쇄장치로 사용되는 오버슬램범퍼의 파지부에 돌기부를 형성하여 오버슬램범퍼의 착탈 작업시 돌기부에 의해 손이 미끄러지는 현상을 방지하여 보다 신속하고 편리하게 오버슬램범퍼의 착탈작업을 수행할 수 있는 자동차 후드용 충격 감쇄장치에 관한 것이다.
The present invention relates to an impact damping device for an automobile hood, and more particularly, to form a protrusion on a gripping portion of an overslam bumper to be used as a hood shock damping device to prevent a hand from slipping by a protrusion during detachment work of an overslam bumper. The present invention relates to an impact damping device for an automobile hood, which can prevent the overslam bumper from being detached more quickly and conveniently.

일반적으로 자동차의 개폐가 가능한 곳 즉, 후드나 도어 또는 트렁크 리드와 같은 개폐부재가 접촉하는 차체에는 완충부재로 이루어진 오버슬램범퍼가 설치된다.In general, an overslam bumper made of a cushioning member is installed at a place where the opening and closing of a vehicle, that is, a vehicle body contacting an opening and closing member such as a hood, a door, or a trunk lid.

이러한 오버슬램범퍼는 개폐부재가 닫힐때 그 충격력이 차체에 전달되는 것을 차단함은 물론 개폐부재의 변형을 방지하기 위하여 완충력이 우수한 탄성체로 이루어진다.The overslam bumper is made of an elastic body having excellent cushioning force to prevent the deformation of the opening and closing member as well as blocking the impact force is transmitted to the vehicle body when the opening and closing member is closed.

특히, 엔진룸을 보호하기 위해 설치되는 후드의 경우에는 엔진룸내에 설치되는 동력전달장치의 진동으로 인해 많은 영향을 받기 때문에 더욱 오버슬램범퍼의 중요성이 강조된다.In particular, in the case of a hood installed to protect the engine room, the importance of the overslam bumper is further emphasized because it is greatly affected by the vibration of the power transmission device installed in the engine room.

그러나 종래 후드에 사용되는 오버슬램범퍼는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.However, the overslam bumper used in the conventional hood has many problems, which will be described in detail as follows.

즉, 도 1 내지 도2 에서 도시한 바와같이 오버슬램범퍼(20)는 하단에 나선 결합부(21)가 형성되고 상단에는 파지부(22)가 형성되어 있어 오버슬램범퍼(20)를 후드 인너판넬(10)에서 착탈하고자 할 경우에는 오버슬램범퍼(20)의 파지부(22)를 잡은 상태에서 후드 인너판넬(10)의 결합공(도면중 미도시)에 오버슬램범퍼(20)의 결합부(21)를 끼워 오버슬램범퍼(20)를 회전시키면 오버슬램범퍼(20)가 후드 인너판넬(10)에 설치되는 것이다.That is, as illustrated in FIGS. 1 and 2, the overslam bumper 20 has a spiral coupling portion 21 formed at a lower end thereof, and a grip portion 22 formed at an upper end thereof, so that the overslam bumper 20 is hood-innerd. When detaching from the panel 10, the overslam bumper 20 is coupled to a coupling hole (not shown) of the hood inner panel 10 while holding the grip portion 22 of the overslam bumper 20. When the overslam bumper 20 is rotated by inserting the part 21, the overslam bumper 20 is installed in the hood inner panel 10.

그런데 종래 오버슬램범퍼(20)의 상단 파지부(22)는 외주연이 매끄러운 상태이므로 작업자가 파지부(22)를 잡은 상태에서 오버슬램범퍼(20)를 회전 시킬때 손이 쉽게 미끄러져 오버슬램범퍼(20)의 착탈작업시 그만큼 작업성이 떨어지는 문제점이 있는 것이다.However, since the upper grip portion 22 of the conventional overslam bumper 20 has a smooth outer circumference, the hand slides easily when the operator rotates the overslam bumper 20 while holding the grip portion 22. When the detachment work of the bumper 20 there is a problem that the workability falls.

또한 종래에는 후드를 닫을시 오버슬램범퍼(20)의 파지부(22)상면 전체가 차체판넬(도면중 미도시)에 접촉되므로 그만큼 충격에너지를 흡수 상쇄시키는 기능이 떨어져 후드를 효율적으로 보호하지 못함은 물론 소음도 효과적으로 저감시키지 못한 문제점이 있었다.
In addition, since the entire upper surface of the holding portion 22 of the overslam bumper 20 contacts the vehicle body panel (not shown in the drawing) when the hood is closed, the function of absorbing and canceling the impact energy is not enough to effectively protect the hood. Of course, there was a problem that did not effectively reduce the noise.

이에 본 발명은 이와같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 오버슬램범퍼의 착탈작업을 신속하고 편리하게 하여 조립성을 향상시킬 수 있을 뿐만 아니라 후드를 닫을 때 발생되는 충격에너지를 흡수하여 상쇄시키는 기능이 탁월하여 후드를 보호함은 물론 소음을 저감시킬 수 있도록 한 자동차 후드용 충격감쇄장치를 제공하기 위한 것이다.

이러한 본 발명은 자동차의 후드 인너판넬(100) 양쪽에 형성된 나선형 결합공(110)에 오버슬램범퍼(200) 하단의 나선 결합부(210)를 결합하여 후드를 여닫을 때의 충격을 감쇄시켜주는 자동차 후드용 충격 감쇄장치에 있어서, 오버슬램범퍼(200) 상단의 파지부(220) 외주면 둘레에는 일정간격으로 다수의 미끄럼방지용 돌기부(221)를 형성하고, 오버슬램범퍼(200)의 파지부(220) 상면에는 요입부(222)를 형성하여 파지부(220) 상면의 테두리부(223)만이 차체판넬(300)에 접촉되게 한 것을 특징으로 한다.The present invention is coupled to the helical coupling hole 110 formed on both sides of the hood inner panel 100 of the vehicle coupled to the spiral coupling portion 210 of the bottom of the overslam bumper 200 to reduce the impact of opening and closing the hood In the hood shock attenuator, a plurality of non-slip protrusions 221 are formed around the outer circumferential surface of the upper portion of the overslam bumper 200 at regular intervals, and the holding portion 220 of the overslam bumper 200 is formed. The upper surface of the gripping portion 222 is formed so that only the edge portion 223 of the upper surface of the gripping portion 220 is characterized in that the body panel 300 in contact.

이와같은 본 발명은 후드를 닫을 때 발생되는 충격에너지를 감쇄토록 하고, 엔진을 비롯한 여러가지 동력전달장치의 진동이 후드에 전달되는 것을 방지하기 위하여 후드 인너판넬(100)에 오버슬램범퍼(200)를 설치토록 하는 것은 일반적인 기술구성이다.The present invention to attenuate the impact energy generated when closing the hood, and to prevent the vibration of the various power transmission devices including the engine to be transmitted to the hood overslam bumper 200 to the hood inner panel (100). Installation is a common technical configuration.

그러나 본 발명에서의 특징은 오버슬램범퍼(200)의 형상을 변형시켜 오버슬램범퍼(200)를 후드 인너판넬(100)에서 착탈시 보다 신속하고 편리하게 작업 할수 있도록 하여 조립성이 향상되도록 한 것이다.However, a feature of the present invention is to modify the shape of the overslam bumper 200 to make the overslam bumper 200 work faster and more convenient when detachable from the hood inner panel 100 to improve the assembly. .

즉, 본 발명은 도 3 에서와 같이 오버슬램범퍼(200)의 상단 파지부(220)외주면에 일정간격의 미끄럼방지용 돌기부(221)를 형성하였다.That is, the present invention, as shown in Figure 3 formed a non-slip projection 221 at a predetermined interval on the outer peripheral surface of the upper grip portion 220 of the overslam bumper 200.
