본 고안은 자동차 후드(HOOD) 완충장치에 관한 것으로, 보다 상세하게는 후드 개폐시 충격치를 감소시켜 충격음을 제거하고 차체의 파손을 방지하기 위한 후드 완충장치에 관한 것이다.The present invention relates to an automobile hood (HOOD) shock absorber, and more particularly to a hood shock absorber to reduce the impact value when opening and closing the hood to remove the impact sound and to prevent damage to the vehicle body.
일반적으로 자동차 후드에는 오버슬램범퍼(OVER/SLAM BUMPER)가 설치되어 있어 후드 개폐시 완충역할을 하게 되어 있는바, 종래의 후드 오버슬램범퍼는 제2도에 도시된 바와같이 고무 등과 같이 충격흡수성이 좋은 재질의 작은 원기둥 외주에 나선형 홈(3)이 형성되어 있고, 상기 나선형 홈(3)이 차체패널(1)에 끼워지도록 구성되어져 후드(2) 개폐시 상기 나선형 홈(3)이 후드(2)와 차체패널(1) 사이에서 압축되면서 완충되어 충격을 흡수하게 되어있다.In general, an overslam bumper (OVER / SLAM BUMPER) is installed on the hood of a car to play a buffer role when the hood is opened and closed. The conventional hood overslam bumper has a shock absorbing property such as rubber as shown in FIG. The spiral groove 3 is formed on the outer circumference of a small cylinder of good material, and the spiral groove 3 is configured to be fitted to the body panel 1 so that the spiral groove 3 is opened when the hood 2 is opened or closed. ) Is absorbed while absorbing the shock while being compressed between the body panel (1).
그러나, 이와같은 오버슬램범퍼는 후드(2)의 개폐횟수가 많아짐에 따라 탄력재질의 오버슬램범퍼(4)가 찢어지거나 압착된 상태로 변형되어 원래의 완충작용을 하지 못하게 되거나(특히 겨울철에는 저온으로 인하여 딱딱하게 됨) 충격흡수 구간이 짧아 충격력을 충분히 흡수하지 못하게 되어 개폐시 소음이 크게 발생하고 충격에 의해 차체의수명을 단축하게 되는등의 여러 결점이 있었다.However, as the number of opening and closing of the hood 2 increases, the overslam bumper 4 is deformed into a torn or compressed state of the elastic material, thereby preventing the original buffering function (especially in the winter, low temperature). Due to the short impact absorption section, the shock absorbing section is not absorbed sufficiently. Therefore, there are various defects such as the noise generated largely when opening and closing, and the life of the vehicle is shortened by the impact.
본 고안은 이와같은 점을 감안하여 안출한 것으로 후드에 개폐시 발생되는 충격이 스프링이 탄지된 커넥팅로드에 의해 흡수되도록 함으로써 충격 흡수율이 우수한 동시에 충격 흡수율을 조절할 수 있는 후드 완충장치를 제공하는데 그 목적이 있는 것이다.The present invention has been devised in view of such a point, and the shock generated when the hood is opened and closed is absorbed by the spring-tight connecting rod, thereby providing a shock absorber having a good shock absorption rate and controlling the shock absorption rate. Is there.
이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
본 고안은 양 지지간(a,b)을 갖는 브라켓(13)을 후드(12)에 설치하고, 상기 양지지간(a,b) 사이에 나사부(21)가 형성된 커넥팅로드(14)를 회동 가능하게 핀 결합하며, 상기 커넥팅로드(14)에는 압축스프링(15)을 끼우는 한편, 중앙에 리벳결합부(16')가 단이지게 형성된 판브라켓(16)을 차체패널(11)에 설치하고, 상기 리벳결합부(16')에 양 지비벽(17,17')이 형성된 로드가이드(18)를 회동 가능하게 리벳(19) 결합하며, 상기 양 지지벽(17,17')에는 안내공(20)을 각각 형성하여 상기 커넥팅로드(14)가 끼워져 미끄럼 이동하며 탄지되게 이루는 완충장치이다.According to the present invention, the bracket 13 having both support sections a and b is installed on the hood 12, and the connecting rod 14 having the screw portion 21 formed therebetween is pivotable. Pin-fitting, the connecting rod 14 is fitted with a compression spring 15, while the rivet coupling portion 16 'in the center of the plate bracket 16 is formed in the body panel 11, Rivets 19 are rotatably coupled to the rod guides 18 on which both gibi walls 17 and 17 'are formed on the rivet coupling portions 16', and guide holes 20 are provided on the support walls 17 and 17 '. And each of the connecting rods 14 is inserted into the sliding slides to be hardened.
여기서, 커넥팅로드(14)에는 제3도에서와 같이 나사부(21)가 형성되고, 그 위에 너트(22)를 나합시켜 압축스프링(15)의 완충작용을 조절할 수 있게 된다.Here, the threaded portion 21 is formed in the connecting rod 14 as shown in FIG. 3, and the nut 22 is screwed thereon to adjust the buffering action of the compression spring 15.
제4도는 본 고안의 완충장치를 후드의 힌지축(A) 부위에 설치된 상태도로써, 차체내부측패널(11)에 판브라켓트(16)가 설치되며, 그위에 안내공(20)이 형성된 로드가이드(18)가 회동가능하게 리벳(19) 고정되어 있으며, 후드(12)에는 브라켓트(13)가 설치되고, 상기 브라켓트(13)에 압축스프링(15)이 끼워진 커넥팅로드(14)가 핀 고정되어 상기 차체패널(11)에 설치된 로드가이드(18)의 안내공(20)에 끼워져 미끄럼 이동하게 됨을 보여준다.4 is a state diagram in which the shock absorber of the present invention is installed on a hinge shaft (A) portion of a hood, and a plate bracket (16) is installed on an inner panel (11) of a vehicle body, and a rod guide (20) is formed thereon. (18) is rotatably fixed to the rivet (19), the hood 12 has a bracket 13 is installed, the connecting rod 14, the compression spring 15 is fitted to the bracket 13 is pinned The sliding guide is inserted into the guide hole 20 of the rod guide 18 installed in the body panel 11.
여기서, 로드가이드(18)가 판브라켓트(16)에 리벳고정되어 회전하게 되고, 커넥팅로드(14)가 브라켓트(13)에 피벗결합되어 회전하도록 구성한 것은 후드(12)가 힌지축(A)을 중심으로 원운동하게 되므로 이에 따른 커넥팅로드(14)의 각 변환을 흡수하게 하기 위함이다.Here, the rod guide 18 is rotated by riveting the plate bracket 16, the connecting rod 14 is pivotally coupled to the bracket 13 is configured to rotate the hood 12 is hinge shaft (A) Since the circular motion to the center to absorb the angular transformation of the connecting rod 14 accordingly.
이하, 이와같이 구성된 본 고안의 작용효과를 설명한다.Hereinafter, the effect of the present invention configured as described above will be described.
로드가이드(18)가 회전될 수 있게 리벳 고정된 판브라켓트(16)가 차체패널(11)에 고정 설치되고, 커넥팅로드(014)가 핀 고정된 브라켓트(13)는 후드(12)에 설치되며, 상기 커넥팅로드(14)가 로드가이드(18)의 안내공(20)에 끼워져 있는 상태에서 후드(12)를 열면 상기 커넥팅로드(143)는 로드가이드(18)의 안내공(20)내에서 미끄럼 이동하며 압축스프링(15) 이완되어 있게 되고, 후드(12)를 닫게 되면 상기 후드(12)에 설치된 브라켓트(13)는 후드(12)의 힌지축(A)을 중심으로 원을 그리며 내려오게 되면서 제5도와 같이 로드가이드(18)와 커넥팅로드(14)와 너트(22) 사이에 압축스프링(15)이 압축되어 충격을 흡수하게 된다.A plate bracket 16 riveted to allow the rod guide 18 to be rotated is fixed to the body panel 11, and a bracket 13 to which the connecting rod 014 is pinned is installed to the hood 12. When the hood 12 is opened while the connecting rod 14 is fitted in the guide hole 20 of the rod guide 18, the connecting rod 143 is formed in the guide hole 20 of the rod guide 18. When the compression spring (15) is slid and the hood (12) is closed, the bracket (13) installed on the hood (12) descends in a circle around the hinge axis (A) of the hood (12). As shown in FIG. 5, the compression spring 15 is compressed between the rod guide 18, the connecting rod 14, and the nut 22 to absorb the impact.
이때 후드의 충격 흡수율을 조정하고자 할때에는 커넥팅로드(14)의 너트(22)를 돌려서 압축스프링(15)의 완충작용력을 보강 또는 완화되게 조절하게 된다.In this case, when adjusting the shock absorption rate of the hood, by turning the nut 22 of the connecting rod 14, the buffering force of the compression spring 15 is adjusted to be reinforced or relaxed.
이상에서 상술한 바와같이 후드의 개폐시 보다 우수한 완충작용을 제공할 수 있을 뿐만 아니라 본 고안의 완충장치가 후드(12)의 힌지축(A) 부근에 설치됨으로서 외관상 눈에 잘 띄지 않는 장점이 있는 것이다.As described above, the shock absorber of the present invention may be provided near the hinge shaft A of the hood 12, as well as providing a better shock absorbing effect when the hood is opened and closed. will be.
