By fixing so that the cross-section having a space 11 therein is formed in a box shape, by reinforcing the structural rigidity of the panels 10, 20 constituting the cowl box to enhance the shock absorption function do.

또한, 상기 공간부(11)에는 저부 가로면이 돌출연장된 ㄷ자 단면을 갖는 주보강부재(40)의 양단에 각각 보조보강패널을 이용하여 카울외측패널(10)과 카울내측패널(20) 및 카울내측패널(20)과 수평보강부재(30b)의 연접된 부위에 각각 연접시킴으로써, 상기 각 패널(10), (20)의 자체 강성 및 구조적 강성을 더욱 더 보완시켜 주게 된다.In addition, the space 11 has a cowl outer panel 10 and a cowl inner panel 20 using auxiliary reinforcement panels at both ends of the main reinforcing member 40 having a U-shaped cross section protruding from the bottom. By connecting the inner portion of the cowl inner panel 20 and the horizontal reinforcing member (30b), respectively, to further complement its own rigidity and structural rigidity of each panel (10), (20).

상기 수직보강패널(30a)과 수평보강패널(30b)은 상기 카울박스와 동일한 길이를 갖는 판체로 이루어져 있으며, 그 일측면이 서로 연접되어 전체적으로 ㄴ단면을 가지도록 연접되어 있다.The vertical reinforcement panel 30a and the horizontal reinforcement panel 30b are made of a plate body having the same length as the cowl box, and one side surface thereof is connected to each other to have a b-section as a whole.

이와 같이 ㄴ자 단면으로 연접된 상기 수직, 수평보강패널(30a), (30b)의 양단면은 각각 ㄱ자 단면으로 연접된 상기 카울외측패널(10) 및 카울내측패널(2O)과 연접고정되면서 내부에 소정의 크기를 갖는 공간부(11)가 형성된 상자형 단면으로 조합되어 있다.As described above, both end surfaces of the vertical and horizontal reinforcement panels 30a and 30b connected to the c-shaped cross section are connected to and fixed to the cowl outer panel 10 and the cowl inner panel 20, respectively. The space 11 having a predetermined size is combined into a box-shaped cross section.

특히, 상기 수평보강패널(30b)의 후단면을 ㄷ자 단면으로 구배시켜 그 세로면이 상기 카울내측패널(20)의 저부면과 밀착되면서 그 후단이 카울내측패널(20)과 일체로 연접고정시켜, 이것들(20), (30b)의 구조적 강성을 더욱 강화시킬 수 있게 하는 것이 바람직하다.In particular, the rear end surface of the horizontal reinforcement panel (30b) is gradient to the U-shaped cross-section so that the vertical surface is in close contact with the bottom surface of the cowl inner panel 20, and the rear end is integrally connected to the cowl inner panel (20). It is desirable to be able to further strengthen the structural rigidity of these 20 and 30b.

이같은 상기 카울박스는 상기 수직, 수평패널(30a), (3Ob)의 연접부위가 상기 대시패널(5O)의 상단에 융착고정되어 상기 카울외측패널(17)과 카울내측패널(10) 및 수직, 수평패널(30a), (30b)의 구조적 강성을 높여주게 되고, 이에 따라 전체적으로 카울박스의 자체 강성을 높일 수 있어서, 정면 충돌시 발생된 충격을 원활하게 흡수할 수 있게 된다.The cowl box is fused and fixed to the upper end of the dash panel 50, the vertical, horizontal panel 30a, 30b, the cowl outer panel 17 and the cowl inner panel 10 and vertical, The structural rigidity of the horizontal panels 30a and 30b is increased, and thus, the overall rigidity of the cowl box can be increased, so that the impact generated during the frontal collision can be smoothly absorbed.

또한, 상기 공간부(11)의 내부에는 주보강패널(40)이 두개의 보조보강패널(41)에 의해 융착고정되어 있다.In addition, the main reinforcement panel 40 is fused and fixed by two auxiliary reinforcement panels 41 inside the space 11.

상기 주보강패널(40)은 저부 가로면이 돌출연장된 ㄷ자 단면의 판체로 이루어져 있다.The main reinforcement panel 40 is composed of a plate body of the U-shaped cross section protruding the bottom horizontal surface.

이러한 주보강패널(40)은 그 양측면에 각각 보조보강패널(41) 이 융착고정되어 있다.In the main reinforcement panel 40, the auxiliary reinforcement panel 41 is fused and fixed to both sides thereof.

상기 한쌍의 보조보강패널(41)은 소정의 곡률로 구배진 단면을 갖는 판체로 이루어져 있으며, 상기 주보강패널(40)의 양측면에 각각 연접되면서 다른 일측면은 카울외측패널(10)과 카울내측패널(20) 및 카울내측패널(20)과 수평보강부재(30b)의 연접부위에 연접고정되어 있다.The pair of auxiliary reinforcement panel 41 is composed of a plate body having a gradient cross section with a predetermined curvature, the other side is connected to both sides of the main reinforcement panel 40, the other side of the cowl outer panel 10 and the cowl inside The panel 20 and the cowl inner panel 20 and the horizontal reinforcing member 30b are connected to each other in a fixed position.

따라서, 상기 주보강패널(40)은 그 세로면이 상기 카울박스의 전면을 향하도록 설치되어 있어서, 정면 충돌에 따른 충격으로 상기 수직보강패널(30a)이 카울박스의 안쪽으로 밀려 들어옴에 따라 이것(30a)과 밀착되어 굽혀지면서 부차적으로 충격을 흡수할 수 있게 된다.Therefore, the main reinforcement panel 40 is installed so that its vertical surface faces the front side of the cowl box, and as the vertical reinforcement panel 30a is pushed into the cowl box by the impact due to the frontal collision. While being in close contact with the 30a and bent, it is possible to additionally absorb the impact.

또한, 상기 대시패널(50)의 세로면 안쪽에는 계단 형상으로 구배진 단면을 갖는 보강부재의 선단과 일체로 융착고정시켜 대시패널(50)의 자체 강성을 보강할 수 있게 하는 것이 바람직하다.In addition, the inner side of the dash panel 50 is preferably integrally fused and fixed to the front end of the reinforcing member having a gradient cross section in a step shape so as to reinforce the rigidity of the dash panel 50.

이상에서 본 바와 같이 본 발명은 ㄴ자 형상의 카울내측패널을 수직으로 구배되게 하면서 이것과 카울외측패널의 일단면에 각각 직각으로 연접된 수직, 수평보강패널의 양측면을 일체로 연접고정시켜, 전체적으로 상자형 단면으로 조합함으로써, 카울박스를 구성하는 각 패널들의 구조적 강성을 강화시켜, 정면충돌에 따른 충격을 원활하게 흡수할 수 있는 효과가 있다.As described above, the present invention is to vertically gradient the c-shaped cowl inner panel while integrally connecting both sides of the vertical and horizontal reinforcement panels connected at right angles to one end surface of the cowl outer panel, thereby integrally connecting the box as a whole. By combining into a cross section, the structural rigidity of each panel constituting the cowl box is strengthened, so that an impact due to a frontal collision can be smoothly absorbed.
