본 고안은 본네트형 자동차에서 앞유리(윈드 쉴드 글래스)와 후드 사이에 위치하고 대시 패널 상단과 용접되며 실내의 계기판을 포함하는 글래쉬 패드 전방에 위치하고 외부의 신선한 공기를 실내로 유입시킬 수 있는 카울의 정면충돌에 대한 강성보강구조에 관한 것이다.The present invention is located between the windshield (wind shield glass) and the hood in the bonnet type car, welded to the top of the dash panel, and located in front of the glass pad including the instrument panel in the room, which is capable of introducing fresh air into the room. The present invention relates to a rigid reinforcement structure for frontal collisions.
종래의 카울은 제3도와 같이 상측에 카울 아웃터 패널(21)을, 엔진 룸 쪽으로는 카울 프론트 아웃터 패널(22)을, 실내쪽으로는 카울 인너 로워 패널(23)을 위치시켜 상기 3개의 패널 단부에 형성되는 플랜지를 각각 스포트용접으로 접합한 박스형을 취하고 있다.In the conventional cowl, as shown in FIG. 3, the cowl outer panel 21 is positioned on the upper side, the cowl front outer panel 22 is positioned toward the engine room, and the cowl inner lower panel 23 is positioned toward the interior. Each flange is formed in a box shape in which spot welding is performed.
이러한 카울은 정면충돌시 후드와 엔진 등에 의하여 실내측으로 가해지는 동하중(충격하중)에 따라 충격에너지의 작용방향으로 주로 굽힘모멘트를 작용받게 되는데 그에 대한 강도가 약해 쉽게 변형되어 실내로 밀려들어 오므로 해서 운전자를 포함하는 승객에게 치명적인 위해를 가하는 문제를 가지고 있었다.These cowls are mainly subjected to bending moments in the direction of impact energy due to dynamic loads (impact loads) applied to the interior by hoods and engines during frontal collisions. Had the problem of causing fatal harm to passengers including drivers.
본 고안의 목적은 차량의 정면충돌시 가해지는 충격하중에 의하여 쉽게 변형되지 않도록 충격 에너지의 작용방향으로 강성을 갖게 하여 승객을 보호코자 하는데 있는 것이다.An object of the present invention is to protect the passengers by making the rigidity in the direction of the impact energy so that it is not easily deformed by the impact load applied during the frontal collision of the vehicle.
본 고안은 상기 목적을 달성하기 위하여, 중간이 분리된 상태로 장고형을 이루며 대칭되게 배치되는 제1보강부재와 제2보강부재, 그리고 중간이 분리된 상태로 장고형을 이루며 대칭되게 배치되는 제3보강부재와 제4보강부재를 충격하중의 분산이 가능하게 각각 카울 아웃터 패널과 카울 프론트 아웃터 패널 내에 상하방향으로 용접하고, 상기 제1보강부재와 상기 제2보강부재의 사이, 그리고 상기 제3보강부재와 상기 제4보강부재의 사이에 충격하중의 흡수가 가능하게 각각 제1지지부재와 제2지지부재를 용접시킨 단면형상으로 구성한 것이다.The present invention is to achieve the above object, the first reinforcing member and the second reinforcing member is formed symmetrically arranged in a state in which the middle is separated, and the first reinforcing member in a state in which the middle is separated and arranged symmetrically The third reinforcing member and the fourth reinforcing member are welded in the cowl outer panel and the cowl front outer panel in the vertical direction so as to distribute the impact load, respectively, between the first and second reinforcing members and the third reinforcing member. The first load member and the second support member are respectively welded in cross-sectional shape so as to absorb the impact load between the reinforcement member and the fourth reinforcement member.
이하 본 고안의 실시예를 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.
본 고안은 제2도와 같이 단면구조상 상측에 카울 아웃터 패널(1)을, 엔진 룸쪽으로는 카울 프론트 아웃터 패널(2)을, 실내쪽으로는 카울 인너 로워 패널(3)을 위치시켜 상기 3개의 패널 단부에 형성되는 플랜지를 각각 스포트용접으로 접합한 박스형을 취하는 자동차의 카울에 있어서, 중간이 분리된 상태로 장고형을 이루며 대칭되게 배치되는 제1보강부재(4)와 제2보강부재(5)의 상하단 플랜지, 그리고 중간이 분리된 상태로 장고형을 이루며 대칭되게 배치되는 제3보강부재(6)와 제4보강부재(7)의 상하단 플랜지를 각각 카울 아웃터 패널(1)과 카울 프론트 아웃터 패널(2)내에 상하방향으로 용접하고, 상기 제1보강부재(4)와 상기 제2보강부재(5)의 사이, 그리고 상기 제3보강부재(6)와 상기 제4보강부재(7)의 사이에 각각 제1지지부재(8)와 제2지지부재(9)의 양측 플랜지를 용접시킨 것이다. 상기 제1보강부재(4)의 중간부위는 카울 프론트 아웃터 패널(2)과 접하고 있고, 제4보강부재(7)의 중간부위는 카울 인너 로워 패널(3)과 접하고 있다.In the present invention, as shown in FIG. 2, the cowl outer panel 1 is positioned on the upper side of the cross section, the cowl front outer panel 2 is located toward the engine room, and the cowl inner lower panel 3 is located toward the inside of the engine. In a cowl of a motor vehicle having a box shape in which flanges formed at each of the flanges are joined to each other by spot welding, the middle of the first reinforcing member 4 and the second reinforcing member 5 which are arranged symmetrically and are arranged symmetrically. The upper and lower flanges and the upper and lower flanges of the third reinforcing member 6 and the fourth reinforcing member 7 which are arranged symmetrically and symmetrically arranged with the middle separated therein are respectively a cow outer panel 1 and a cow front outer panel ( 2) welding in the vertical direction, between the first reinforcing member 4 and the second reinforcing member 5, and between the third reinforcing member 6 and the fourth reinforcing member 7 Both sides of the first support member 8 and the second support member 9, respectively It was welded Flange. The middle portion of the first reinforcing member 4 is in contact with the cowl front outer panel 2, and the middle portion of the fourth reinforcing member 7 is in contact with the cowl inner lower panel 3.
따라서 카울 내는 격자구조를 띄고 있어 충격하중에 대한 강성을 갖고 외력을 서로 분산시키는 기능을 하게 된다.Therefore, the cowl has a lattice structure, which has a rigidity against impact loads and distributes external forces.
본 고안은 차량의 정면충돌시 충격하중이 카울 아웃터 패널(1)과 카울 프론트 아웃터 패널(2)쪽에 가해지면 제1보강부재(4)와 제2보강부재(5), 제3보강부재(6) 및 제4보강부재(7)로 가면서 충격하중이 분산되므로 그 충격에너지가 흡수되고, 제1지지부재(8)와 제2지지부재(9)는 중간이 하향으로 꺾어지면서 그 충격에너지를 흡수하게 되는 것이다.According to the present invention, when an impact load is applied to the cowl outer panel 1 and the cowl front outer panel 2 during the frontal collision of the vehicle, the first reinforcing member 4, the second reinforcing member 5, and the third reinforcing member 6 are applied. And the impact load is distributed to the fourth reinforcing member 7, so that the impact energy is absorbed, and the first support member 8 and the second support member 9 absorb the impact energy while being bent downward in the middle. Will be done.
이와 같은 본 고안은 카울 내에 4개의 보강부재를 2개의 장고형으로 보강설치하고 2개의 지지부재를 보강설치함에 의하여 카울이 강성을 갖게 되고 이에 따라 정면충돌시에 카울이 실내로 밀려들어오는 것을 저지시킬 수 있기 때문에 실내의 승객이 크래쉬 패드 등과의 충돌에 의하여 받게 되는 상해를 그만큼 줄일 수 있게 되는 것이다.This invention is designed to strengthen the cowl by reinforcing the four reinforcing members in the cowl and two reinforcement and by installing the two support members in the cowl, thus preventing the cow from being pushed into the room during a frontal collision. Since the passengers in the room can be injured by the collision with the crash pad, etc., it is possible to reduce that much.
