본 고안은 자동차의 후론트사이드멤버와 후론트거셋트에 관한 것으로, 특히 충돌흡수에 불리한 거셋트, 브라켓트의 일원화구조에서 이를 이원화시켜 본래기능을 수행하면서도 충돌흡수에 유리하도록 한 후론트사이드멤버와 거셋트의 결합구조에 관한 것이다.The present invention relates to a front side member and a front gusset of a car, and in particular, the front side member and gusset of the front side member and gusset which are advantageous in collision absorption while performing the original function by dualizing it in the unified structure of the gusset and the bracket which are disadvantageous to the collision absorption. It relates to a coupling structure.

일반적으로 거셋트(GUSSET)는 하부에 브라켓트가 결합되어 배,기차로 자동차를 운반할 경우에 후크를 걸어주기 위한 것으로, 강성을 고려하여 두께가 두껍고, 대략 ㄷ형으로 형성되어 후론트사이드멤버(FRONT SIDE MEMBER)를 감싸는 구조로 구성되었기 때문에 차량의 전방충돌시 후론트사이드멤버 전방부의 찌그러짐을 방해하여 충분한 충격흡수가 되지 않는 문제점이 있었다.In general, the gusset (GUSSET) is to hang the hook when the car is transported by boat or train by combining the bracket at the bottom, and the thickness is thick in consideration of the rigidity, and is formed in the roughly c-shaped front side member (FRONT SIDE). MEMBER) because of the structure surrounding the front collision of the front of the front side member to prevent the distortion of the front side member there is a problem that does not absorb enough shock.

즉, 종래의 후론트사이드멤버와 거셋트의 결합구조는 제2도와 제3도에 도시되는 바와 같이, 거셋트(1)와 브라켓트(2)가 결합되어 있는 바 그 기능을 설명하면 다음과 같다.That is, the conventional structure of the front side member and gusset is as shown in Figure 2 and 3, the gusset 1 and the bracket (2) is described as follows.

거셋트(1)는 후론트사이드멤버(3)의 하단에 위치하는 라디에터서포트로워멤버(RADIATOR SUPPORT LOWER MEMBER)를 지지하는 역할을 하며, 하단의 브라켓트(2)의 강성을 지지해주는 기능을 수행한다.The gusset (1) serves to support the radiator support lower member (RADIATOR SUPPORT LOWER MEMBER) located at the bottom of the front side member (3), and performs the function of supporting the rigidity of the bracket (2) at the bottom.

상기 브라켓트(2)는 배 또는 기차로 자동차를 운반할 경우에 후크걸이홀(4)에 후크(HOOK)를 걸어 차량을 고정시키는 역할을 수행하며, 운반시 장시간부하나 일시적인 큰 충격에 견딜 수 있는 충분한 강도가 요구되며, 이를 위하여 거셋트(1)의 두께를 두껍게 올리고, 후론트사이드멤버(3)를 ㄷ자형으로 감싸는 구조를 이루어 그 강성을 부여하였다.The bracket 2 serves to fix the vehicle by hooking the hook hook hole 4 when the vehicle is to be transported by ship or train, and can withstand a long time load or temporary large impact during transportation. Sufficient strength is required, and for this purpose, the gusset 1 is thickened, and the front side member 3 is surrounded by a U-shape to give a rigidity.

그러나, 상기에서와 같은 종래의 결합구조는 컴퓨터에 의한 충돌해석(CAE) 결과 종래의 거셋트구조가 후론트사이드멤버(3) 전방부의 찌그러짐을 방해하는 작용을 하여 충분한 충격흡수가 되지 않고, 이로 인하여 차내의 승객이 받는 충격량이 커지게 되는 문제점이 있었다.However, in the conventional coupling structure as described above, the conventional gusset structure prevents the front part of the front side member 3 from crushing as a result of the collision analysis (CAE) by the computer, and thus does not provide sufficient shock absorption. There was a problem that the amount of impact received by the passengers in the car increases.

제2도와 제3도에서 도면 중 미설명부호 3a는 후론트사이드인어멤버, 3b는 후론트사이드아웃터멤버, 4a는 환봉을 각각 나타낸 것이다.In FIG. 2 and FIG. 3, reference numeral 3a denotes a frontside in member, 3b a frontside outer member, and 4a a round bar.

본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해, 거셋트의 본래기능을 수행하면서도 충돌흡수에 유리하도록 종래 거셋트, 브라켓트의 일체식구조에서 이원화구조를 이루어 브라켓트는 후론트사이드멤버의 측벽부에 3점볼팅결합으로 고정시키고, 거셋트는 두께를 약화시키고, 충돌방향에 대하여 찌그러짐을 유도한 그루브를 추가하여 전체적으로 충돌흡수에 유리하게 약화시키면서도 그 기능을 수행할 수 있도록 한 후론트사이드멤버와 거셋트의 결합구조를 제공하는 데 있다.The purpose of the present invention is to solve the conventional drawbacks as described above, while performing the original function of the gusset while forming a dual structure in the integrated structure of the conventional gusset, bracket to the advantage of the collision absorbing bracket of the front side member The front side member is fixed to the side wall by a three-point bolting coupling, and the gusset weakens its thickness and adds grooves that induce distortion in the collision direction so that it can perform its functions while weakening the overall impact absorption. It is to provide a coupling structure of and gusset.

이하 첨부된 도면에 따라서 본 고안의 기술적 구성을 상세히 설명하명 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail as follows.

본 고안은 제4도 내지 제6도에 도시되는 바와 같이, 후론트사이드멤버(10)의 단면구조를 변경하여 상단부의 플랜지(11a)(12a)를 평면과 나란하도록 형성하고, 후론트사이드아웃터멤버(12)의 플랜지(12b)를 연장하며, 후론트사이드인어멤버(11)는 플랜지(11b)를 후론트사이드아웃터멤버(12)와 용접결합할 수 있도록 적정량 연장하였다.The present invention, as shown in Figures 4 to 6, by changing the cross-sectional structure of the front side member 10 to form the flange (11a) (12a) of the upper end in parallel with the plane, the front side outer member ( The flange 12b of 12) was extended, and the front side in-member member 11 was extended in an appropriate amount so that the flange 11b could be welded to the front side outer member member 12.

상기 후론트사이드아웃터멤버(12)의 연장된 플랜지(12b)와 본 고안에 의한 거셋트(20)의 외측면 플랜지(21)를 스폿용접으로 결합하며, 거셋트(20)의 내측면에 형성된 수직부(22)는 후론트사이드인어멤버(11)의 수직부에 용접으로 결합한다.The extended flange 12b of the front side outer member 12 and the outer flange 21 of the gusset 20 according to the present invention are coupled to each other by spot welding, and are formed vertically on the inner side of the gusset 20. The portion 22 is welded to the vertical portion of the front side in-member 11.

한편, 거셋트(20)의 상단면에 형성된 평면부(23)는 후론트사이드인어멤버(11)의 하단부에 용접결합하고, 내측면에 형성된 플랜지(24)와 하단부에 형성된 플랜지(25)는 라디에이터서포트로워멤버부와 결합시 용접결합한다.On the other hand, the flat portion 23 formed on the upper surface of the gusset 20 is welded to the lower end of the front side of the member 11, the flange 24 formed on the inner surface and the flange 25 formed on the lower end radiator When joining with the support lower member, weld it.

본 고안에 의한 거셋트(20)의 구조는 라디에이터서포트로워멤버부를 지지하는 본래기능을 수행하면서도 충격흡수에 유리하게 잘 찌그러지도록 철판두께를 줄이고, 충돌방향에 대한 변형유도를 위해 그루브(26)를 형성하며, 후론트사이드멤버(10)의 연장된 플랜지와 ㄴ자형 거셋트구조가 결합된 형태를 이루고 있다.The structure of the gusset 20 according to the present invention reduces the thickness of the steel sheet so as to be distorted in favor of shock absorption while performing the original function of supporting the radiator support lower member, and the grooves 26 for inducing deformation in the collision direction. It is formed, and the extended flange of the front side member 10 and the N-shaped gusset structure is combined form.

또한, 거셋트(20)의 강성이 요구되어온 후론트쉬핑훅 브라켓트(30)를 이원화시켜 후론트사이드아웃터멤버(12)의 측벽전방부에 3점볼팅으로 고정시킬 수 있는 구조를 택하였다. 여기서, 도면 중 미설명부로 31은 볼팅홀, 32는 후크걸이홀을 각각 나타낸 것이다.Also, the front shipping hook bracket 30, which has been required to have rigidity of the gusset 20, was dualized to select a structure capable of fixing it by three-point bolting on the front sidewall of the front side outer member 12. Here, in the drawing, 31 is a bolting hole, and 32 is a hook hook hole.

따라서, 이러한 본 고안은 차량의 전방충돌시 후론트사이드멤버(10) 전방부의 찌그러짐을 유도하여 차내의 승객이 받는 충격량을 줄일 수 있으며, 거셋트(20)와 브라켓트(30)의 이원화로 각각의 본래기능을 수행하면서도 차량 전방부의 충돌흡수에 유리한 장점이 있다.Therefore, the present invention can reduce the amount of impact received by passengers in the vehicle by inducing the front part of the front side member 10 during the front collision of the vehicle, and each original by dualization of the gusset 20 and the bracket 30 While performing the function, there is an advantage in absorbing the collision of the front of the vehicle.

이상에서 설명한 바와 같이 본 고안은 거셋트의 본래기능을 수행하면서도 충돌흡수에 유리하도록 종래 거셋트, 브라켓트의 일체식구조에서 이원화구조를 이루어 브라켓트는 후론트사이드멤버의 측벽부에 3점볼팅결합으로 고정시키고, 거셋트는 두께를 약화시키고, 충돌방향에 대하여 찌그러짐을 유도한 그루브를 추가하여 전체적으로 충돌흡수에 유리하게 약화시키면서도 그 기능을 수행할 수 있는 매우 유용한 고안이다.As described above, the present invention achieves the original function of the gusset, while forming a dual structure in the conventional gusset and the integral structure of the bracket so as to favor the collision absorption, and the bracket is fixed to the side wall of the front side member by three-point bolting coupling. In addition, the gusset is a very useful design that can perform its function while weakening the thickness and adding a groove inducing distortion in the collision direction, while weakening the overall shock absorption.
