본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2 내지 도 6을 참조하면, 본 발명의 일실시예에 따른 다리 상해치 저감을 위한 서브프레임 리어멤버의 충격흡수구조는 차량용 서브프레임 리어멤버의 충격흡수구조에 관한 것으로서, 서브프레임 리어멤버(410)와 변속기 케이스(200) 사이의 공간부(500)에 위치하여 상기 서브프레임 리어멤버(410)의 일측에 고정되고, 육각홀을 가진 기둥이 연속적으로 적층되어 벌집형태로 이루어져 차량의 정면충돌시 상기 변속기 케이스(200)와 맞물려 찌그러지면서 충격을 흡수하는 충격흡수부재(600)를 포함하여 이루어진다.2 to 6, the shock absorbing structure of the subframe rear member for reducing the leg injury value according to an embodiment of the present invention relates to the shock absorbing structure of the vehicle subframe rear member, the subframe rear member ( Located in the space 500 between the 410 and the transmission case 200 and fixed to one side of the rear frame member 410, the pillars having hexagonal holes are successively stacked to form a honeycomb, which is a frontal collision of the vehicle. The shock absorbing member 600 is engaged with the transmission case 200 and crushed to absorb shock.

이하, 본 발명의 일실시예에 따른 다리 상해치 저감을 위한 서브프레임 리어멤버의 충격흡수구조에 대해 보다 구체적으로 설명하기로 한다.Hereinafter, the shock absorbing structure of the subframe rear member for reducing the leg injury value according to an embodiment of the present invention will be described in more detail.

상기 충격흡수부재(600)는 상기 서브프레임 리어멤버(410)와 상기 변속기 케이스(200) 사이의 공간부(500)에 위치하여 상기 서브프레임 리어멤버(410)의 일측에 고정되고, 육각홀을 가진 기둥이 연속적으로 적층되어 벌집형태로 이루어져 차량의 정면충돌시 상기 변속기 케이스(200)와 맞물려 찌그러지면서 충격을 흡수하도 록 마련된다.The shock absorbing member 600 is located in the space 500 between the subframe rear member 410 and the transmission case 200 and is fixed to one side of the subframe rear member 410, and has a hexagonal hole. The pillars are continuously stacked to form a honeycomb, and are provided to absorb the shock while being engaged with the transmission case 200 during a frontal collision of the vehicle.

상기 충격흡수부재(600)는 상기 서브프레임 리어멤버(410)와 상기 변속기 케이스(200) 사이의 공간부(500)에 위치하여 상기 서브프레임 리어멤버(410)의 일측에 고정되는데, 일측에 복수 개의 볼트체결부(610, 620, 630)를 형성해 상기 서브프레임 리어멤버(410)에 볼트 체결되도록 구성되어 탈장착이 용이하도록 마련된다.The shock absorbing member 600 is positioned in the space portion 500 between the subframe rear member 410 and the transmission case 200 and is fixed to one side of the subframe rear member 410, and a plurality of the shock absorbing members 600 are disposed on one side thereof. Bolt fastening portions 610, 620, and 630 are formed to be bolted to the subframe rear member 410, and are provided to facilitate removal of the bolts.

이때, 상기 충격흡수부재(600)는 상기 서브프레임 리어멤버(410)의 일측면과 상면에 볼트 체결하여 3점 마운팅 방식으로 고정될 수 있는데, 상기 충격흡수부재(600)의 양단부 하측에 볼트체결부(610, 630)를 각각 형성하고, 상기 충격흡수부재(600)의 중앙부 상면에 볼트체결부(620)를 형성하여 상기 충격흡수부재(600)를 상기 서브프레임 리어멤버(410)의 일측면과 상면에 3점 마운팅 방식으로 볼트 체결하여 고정시킬 수 있다.At this time, the shock absorbing member 600 may be fixed to the one side and the upper surface of the sub-frame rear member 410 by a three-point mounting method, bolted to the lower end of both ends of the shock absorbing member 600 The parts 610 and 630 are formed, respectively, and a bolt fastening part 620 is formed on an upper surface of the central portion of the shock absorbing member 600 to form the shock absorbing member 600 on one side of the subframe rear member 410. It can be fixed by bolting on the top surface with 3 points mounting method.

상기 충격흡수부재(600)는 육각홀을 가진 기둥이 연속적으로 적층되어 벌집형태로 이루어지도록 마련된다.The shock absorbing member 600 is provided so that the pillars having hexagonal holes are continuously stacked to form a honeycomb.

일반적으로 다각형 중에 가장 둘레면적이 작은 것은 원형이지만, 원형의 경우 적층할 경우 그 사이의 간극이 크고, 육각형의 경우는 적층시 각 모서리가 상호 효과적으로 맞물리는 최적의 도형이므로 이러한 육각홀을 가진 벌집형태의 구조물은 최소의 재료로 최고의 강도를 가지게 되어 충격흡수효과 또한 커지기 때문에 상기 충격흡수부재(600)는 육각홀을 가진 벌집형상으로 이루어지는 것이 바람직하다. Generally, the smallest circumferential area among polygons is circular, but in the case of circular lamination, the gap between them is large. Since the structure has the highest strength with the minimum material, the shock absorbing effect is also increased, so the shock absorbing member 600 is preferably formed in a honeycomb shape having hexagonal holes.

상기 충격흡수부재(600)는 알루미늄, 플라스틱 또는 마그네슘 재질로 마련될 수 있으며, 이러한 재질을 사용하게 되면 경량화 효과를 가질 수 있다.The shock absorbing member 600 may be made of aluminum, plastic, or magnesium, and may have a light weighting effect by using such a material.

도 7은 본 발명의 일실시예에 따른 서브프레임 리어멤버의 충격흡수구조를 갖춘 차량과 종래의 설치구조를 갖춘 차량의 미국보험협회(IIHS)가 실시하는 오프셋(OFFSET)충돌시험을 하였을 때 나타난 데이터 값을 서로 비교한 그래프이다.FIG. 7 shows an offset collision test conducted by the American Insurance Association (IIHS) of a vehicle having a shock absorbing structure of a subframe rear member and a vehicle having a conventional installation structure according to an embodiment of the present invention. A graph comparing data values.

도 7을 참조하면, 차량의 정면 충돌이 발생되면 충돌에너지가 차체의 멤버류와 서브프레임 등의 변형에 의해 흡수되며, 부수적으로 차량의 엔진룸 내부에 설치된 각종 부속품들이 파손되거나 변형이 이루어지고, 충돌에 의한 충격력이 과도한 경우에는 탑승자가 위치한 실내쪽으로 서브프레임 리어멤버(410)가 밀려 들어오면서 대쉬하단부를 붕괴시켜 탑승자의 다리에 치명적인 상해를 입히게 된다.Referring to FIG. 7, when a frontal collision of a vehicle occurs, collision energy is absorbed by deformation of members and subframes of the vehicle body, and additionally, various accessories installed in the engine room of the vehicle are damaged or deformed. If the impact force due to the collision is excessive, the sub-frame rear member 410 is pushed toward the interior of the occupant to collapse the lower part of the dash and cause a fatal injury to the leg of the occupant.

차량의 충돌은 1차충돌과 2차충돌로 구분하여 부르고 있는데 1차충돌은 차체가 변형되는 것을 말하고, 2차충돌은 어느정도 진행된 후 탑승객이 움직이기 시작하여 핸들 또는 차실내 부위에 부딪치는 현상을 말하는데, 미국보험협회(IIHS)가 실시하는 오프셋(OFFSET)충돌시험결과 서브프레임 리어멤버(410)와 변속기 케이스(200) 사이의 공간부(500)에 벌집형태로 이루어진 충격흡수부재(600)를 설치한 경우 10~20ms 구간에서 종래의 설치구조보다 차량의 감가속도가 급격히 증대되고, 40~50ms 구간에서 차량의 감가속도가 급격히 감소되는 결과를 보여주는데, 이것은 1차충돌시 상기 충격흡수부재(600)의 변형에 의해 충격에너지 흡수가 종래의 설치구조보다 향상되었고, 그 결과 2차충돌시 충격에너지가 감소하여 탑승자의 다리상해치가 저감되는 것을 확인시켜 주는 것이다.The collision of the vehicle is divided into the primary collision and the secondary collision. The primary collision refers to the deformation of the body, and the secondary collision is a phenomenon in which passengers start to move and hit the steering wheel or the part of the vehicle interior after a certain progress. That is, the offset (collision) test conducted by the American Insurance Association (IIHS) results in a shock absorbing member 600 having a honeycomb shape in the space 500 between the subframe rear member 410 and the transmission case 200. When installed, the deceleration speed of the vehicle is sharply increased in the 10 to 20ms section than the conventional installation structure, and the deceleration speed of the vehicle is rapidly reduced in the 40 to 50ms section, which is the impact absorbing member 600 during the first collision. ), The impact energy absorption is improved compared to the conventional installation structure, and as a result, the impact energy is reduced during secondary collision, which confirms that the foot injury of the occupants is reduced. will be.

따라서, 본 발명의 일실시예에 따른 다리 상해치 저감을 위한 서브프레임 리어멤버의 충격흡수구조는 서브프레임 리어멤버(410)와 변속기 케이스(200) 사이 의 공간부에 충격흡수부재(600)를 설치함으로써 차량의 정면충돌시 상기 충격흡수부재(600)가 변속기 케이스(200)와 맞물려 찌그러지면서 충격을 흡수하게되어 차체 변형량이 감소되고, 탑승자의 다리에 가해지는 충격을 저감할 수 있게 된다. Therefore, the shock absorbing structure of the subframe rear member for reducing the leg injury value according to an embodiment of the present invention is the shock absorbing member 600 in the space portion between the subframe rear member 410 and the transmission case 200. When installed, the shock absorbing member 600 is engaged with the transmission case 200 when the frontal collision of the vehicle absorbs the shock, thereby reducing the amount of deformation of the vehicle body and reducing the impact on the passenger's leg.
