산업상 이용분야Industrial use field
본원 발명은 차체의 강도를 보강시키고 충돌시 충격을 흡수하여 탑승자의 안전을 도모하기 위하여 차체에 설치되는 충격흡수 빔에 관한 것이다.The present invention relates to a shock absorbing beam which is installed in the vehicle body to reinforce the strength of the vehicle body and absorb the impact in the collision to promote the safety of the occupants.
종래기술Prior art
일반적으로 도어의 충격흡수 빔은 제 2 도 및 제 3 도에서 볼 수 있는 바와같이 도어 아웃터 패널(2) 안쪽에 설치하고 있다. 종래 충격흡수 빔(6)은 통상 단위 중량당의 강도를 높이기 위하여 단면계수가 높은 중공형 파이프로 형성되고 밀봉완충재(sealer, 3)를 개재하여 아웃터 패널(2)을 지지하고 있어 측면 충돌에 의해 아웃터 패널(2)이 차체 내부로 찌그러질 때 변형에 저항하는 버팀대 역할을 하게된다.Generally, the shock absorbing beam of the door is installed inside the door outer panel 2 as shown in FIGS. 2 and 3. Conventional shock absorbing beam (6) is usually formed of a hollow pipe with a high cross-sectional coefficient in order to increase the strength per unit weight, and supports the outer panel (2) via a sealing buffer (sealer, 3) to the outer by the side impact When the panel 2 is crushed into the vehicle body, it serves as a brace against deformation.
종래기술의 문제점Problems of the Prior Art
그런데 각국은 탑승자의 안전을 도모하기 위하여 차체의 강도를 높이도록 규정을 강화하고 있어 이러한 기준을 충족시키기 위해서는 충격흡수 빔(6)의 파이프 직경을 크게 하므로써 충격에 대한 차체의 저항력을 높일 수밖에 없는 실정이다.However, in order to enhance the safety of the occupants, each country has strengthened regulations to increase the strength of the vehicle body. Therefore, in order to meet these standards, it is necessary to increase the resistance of the vehicle body to impact by increasing the pipe diameter of the shock absorbing beam 6. to be.
그러나 충격흡수 빔(6)의 파이프 직경이 커질 경우 상대적으로 도아 내부의 탑승자 공간이 적어지고 설치 위치도 자유롭지 못하다는 문제점이 지적되고 있다.However, it is pointed out that when the pipe diameter of the shock absorbing beam 6 is increased, the occupant space inside the door is relatively small and the installation position is not free.
발명이 해결코자 하는 과제Problems to be Solved by the Invention
본 발명은 상기한 문제점을 해결하기 위해 안출한 것으로서 그의 목적으로 하는바는 충격시 응력집중을 효과적으로 분산하는 구조의 충격흡수 빔을 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and its object is to provide a shock absorbing beam having a structure that effectively disperses stress concentration during impact.
발명의 과제를 달성하기 위한 수단Means for achieving the object of the invention
본 발명은 상기한 목적을 달성하기 위해 원형 파이프 외부에 타원형 파이프를 긴밀하게 끼워 이중 구조로 형성함을 특징으로 한다.The present invention is characterized by forming a double structure by closely fitting the elliptical pipe to the outside of the circular pipe to achieve the above object.
실시예Example
이하 본 발명의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제 1 도는 본 발명 충격흡수 빔의 일실시예를 나타내는 단면도로서 본 발명 충격흡수 빔(1)은 도어 아웃터 패널(2) 안쪽으로 밀봉완충재(3, sealer)를 개재하여 차체 내부로 설치되며 외경 D1을 갖는 원형 파이프(4)외주에 내경부의 단지름 D2와 장지름 D3를 갖는 타원형 파이프(5)를 긴밀하게 끼워 2중 구조체로 형성하였다. 따라서 원형 파이프(4)의 외경 D1과 타원형 파이프(5)의 단지름 D2는 거의 같은 직경을 갖는다.1 is a cross-sectional view showing an embodiment of the shock absorbing beam of the present invention. The shock absorbing beam 1 of the present invention is installed inside the vehicle body through a sealer 3 inside the door outer panel 2 and has an outer diameter D1. An elliptical pipe 5 having a diameter D2 of the inner diameter and a long diameter D3 was closely fitted to the outer circumference of the circular pipe 4 having the shape of a double structure. Therefore, the outer diameter D1 of the circular pipe 4 and the jar diameter D2 of the elliptical pipe 5 have almost the same diameter.
본 발명은 타원형 파이프(5)의 장지름 D3가 세로로 위치하도록 차체내에 내장되며 원형 파이프(4)의 내부는 돌기부(4')를 형성하므로써 힘의 분산을 도모할 수 있다.The present invention is embedded in the vehicle body such that the long diameter D3 of the elliptical pipe 5 is located vertically, and the inside of the circular pipe 4 can form a protrusion 4 ', thereby enabling the dispersion of the force.
발명의 작용 효과Effects of the Invention
이상과 같은 본원 발명에 의하면 동일한 강도를 갖는 하나의 원형 파이프보다 전체 직경(타원형 파이프의 외경부 단지름을 기준)이 작아도 되므로 도어 내부의 공간을 축소시키지 않을 뿐 아니라 장착위치의 조절이 용이하고 충격시 원형 파이프(4)와 타원형 파이프(5)에 의해 충격력을 수평방향과 수직방향으로 분산시키게되며 이중구조체이어서 단일체에 비하여 굽힘 강도가 크게 높아져 탑승자의 안전을 도모할 수 있는 효과가 있다.According to the present invention as described above, since the overall diameter (based on the outer diameter of the elliptical pipe is smaller) than the one round pipe having the same strength, not only does not reduce the space inside the door, but also easy to adjust the mounting position and impact When the circular pipe (4) and the oval pipe (5) to distribute the impact force in the horizontal and vertical direction, and because of the dual structure has a greater bending strength than the single body has an effect that can improve the safety of the occupants.
