본 발명은 자동차에서 카울사이드부와 프론트필라 연결부의 구조에 관한 것으로, 특히 카울사이드부의 비틀림 강성이 향상될 수 있도록 된 자동차의 카울사이드부와 프론트필라 보강구조에 관한 것이다.The present invention relates to a structure of a cowl side part and a front pillar connection part in an automobile, and more particularly, to a cowl side part and a front pillar reinforcement structure of a motor vehicle in which the torsional rigidity of the cowl side part can be improved.

카울(Cowl)은 프론트 윈도우 즉, 윈드쉴드글래스 하측의 차체 횡방향 패널 부분을 말한다.Cowl refers to the front window, that is, the transverse panel portion under the windshield glass.

이 부분은 차체의 횡강성 및 비틀림 강성을 확보하고, 충격흡수를 위한 크로스바 및 차실 공조를 위한 에어덕트 등이 설치되는 부분이다.This part is to secure the lateral rigidity and torsional rigidity of the vehicle body, and is provided with a crossbar for absorbing shock and an air duct for air conditioning.

도 1은 차체의 카울사이드부와 프론트필라 연결부를 평면으로 잘라 도시한 것으로, 도면의 좌측이 앞쪽 즉, 엔진룸 부분이고 우측이 뒤쪽 차실이며, 상측이 차량의 실외 부분에 해당된다.FIG. 1 is a cutaway view of a cowl side part and a front pillar connecting part of the vehicle body in a plan view, in which the left side of the drawing is the front, that is, the engine room part, the right side is the rear compartment, and the upper part corresponds to the outdoor part of the vehicle.

상기 카울사이드부와 프론트필라 연결부는 도시된 바와 같이, 카울탑패널(1)이 차량의 횡방향으로 배치되되, 이와 평행하게 카울탑보강패널(2)이 배치되어 카울사이드어퍼인너패널(3)에 상기 카울탑보강패널(2)의 단부가 용접되고, 상기 카울사이드어퍼인너패널(3)의 단부는 상기 카울탑패널(1)의 전면에 용접된다.The cowl side part and the front pillar connection part, as shown, the cowl top panel 1 is disposed in the transverse direction of the vehicle, the cowl top reinforcement panel 2 is disposed parallel to the cowl upper inner panel (3) An end of the cowl top reinforcement panel 2 is welded, and an end of the cowl upper inner panel 3 is welded to the front surface of the cowl top panel 1.

또한, 프론트필라는 사이드패널조합체(5)의 프론트필라 외측부(6)와 이의 내 측에 용접되는 프론트필라인너패널(7)에 의해 구성되며, 이들의 전방측 접합플랜지에 상기 카울탑패널(1)의 단부가 용접된다.In addition, the front pillar is constituted by the front pillar outer portion 6 of the side panel assembly 5 and the front pillar liner panel 7 welded to the inner side thereof, and the cowl top panel 1 on the front joining flange thereof. End is welded.

그리고, 상기 카울사이드어퍼인너패널(3)의 외측에 소정간격을 두고 배치된 카울사이드어퍼아우터패널(4)의 단부가 상기 프론트필라 외측부(6)에 용접된다.Then, an end portion of the cowl side outer panel 4 disposed at a predetermined interval on the outside of the cowl side inner panel 3 is welded to the front pillar outer portion 6.

또한, 상기 프론트필라인너패널(7)의 실내측면에는 카울크로스바마운팅브라켓(8)이 용접되는 구조로 이루어져 있다.In addition, the interior side surface of the front fill liner panel 7 has a structure in which the cowl cross bar mounting bracket 8 is welded.

즉, 종래에는 카울탑패널(1)과 카울탑보강패널(2) 및 카울사이드어퍼인너패널(3)이 상기 사이드패널조합체(5)의 전방측 접합플랜지에 용접된 카울탑패널(1)의 단부를 통해서만 프론트필라에 연결("A"부)되어 있었기 때문에 용접점의 수가 적을 뿐만 아니라 연결부분이 구조적으로도 한 위치로만 한정되어 있어서 충분한 강성을 확보하기가 곤란하였다. 특히, FR(Front engine/ Rear drive ; 차량 앞쪽에 위치한 엔진으로부터 뒤쪽의 후륜축까지 프로펠라샤프트를 통해 엔진동력이 전달됨)차량에서 요구되는 비틀림강성을 확보하는데 문제가 많았다.That is, in the related art, the cowl top panel 1, the cowl top reinforcing panel 2, and the cowl upper inner panel 3 are welded to the front joining flange of the side panel assembly 5. Since only the end was connected to the front pillar ("A" part), not only the number of welding spots was small but also the connection part was structurally limited to only one position, making it difficult to secure sufficient rigidity. In particular, there were many problems in securing the torsional stiffness required in a front engine / rear drive (FR) vehicle from the engine located in front of the vehicle to the rear axle of the rear.

또한, 종래에는 사이드패널조합체(5)가 완성된 상태 즉, 프론트필라 외측부(6)에 프론트필라인너패널(7)이 용접된 상태(프론트필라인너패널 뿐 아니라 센터필러인너패널 및 루프사이드레일 등이 선 용접되어 사이드패널조합체(5)가 완성된 상태에서 후공정이 이루어진다.)에서 카울탑패널(1)과의 용접이 이루어졌기 때문에, 프론트필라의 내측에 카울부와의 접합부 강성을 향상시켜주는 구조물이 없어서 상기 연결부("A")의 강성 증대에 아무런 도움이 되지 못하였으며, 프론트필라 자체의 강성 확보도 미약하다는 문제점이 있었다.In addition, the state in which the side panel assembly 5 is completed, that is, the front pillar liner panel 7 is welded to the front pillar outer portion 6 (a center pillar inner panel and a roof side rail, etc., as well as the front pillar liner panel). This line is welded to the cowl top panel 1 in the state where the side panel assembly 5 is completed. Since there is no main structure, it did not help to increase the rigidity of the connecting portion ("A"), and there was a problem that the securing of the rigidity of the front pillar itself was also weak.

또한, 이와 같이 자체 강성이 부족한 프론트필라의 프론트필라인너패널(7)에 상기 카울크로스바마운팅브라켓(8)이 용접되어 있으므로 카울크로스바의 장착상태도 견고하지 못하다는 문제점이 있었다.In addition, since the cowl crossbar mounting bracket 8 is welded to the front pillar liner panel 7 of the front pillar which lacks its rigidity, there is a problem in that the cowl crossbar is not firmly mounted.

이에 본 발명은 상기와 같은 문제점들을 해결하기 위하여 안출된 것으로, 카울사이드부와 프론트필라의 연결부 강성을 향상시켜 FR차량에서도 충분한 비틀림 강성을 확보할 수 있게 되고, 프론트필라 자체의 강성도 향상될 뿐만 아니라, 이에 의해 카울크로스바의 장착상태도 견고히 할 수 있도록 된 차체의 카울 사이드부 구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and by improving the rigidity of the connection portion between the cowl side part and the front pillar, it is possible to ensure sufficient torsional rigidity even in the FR vehicle, as well as to improve the rigidity of the front pillar itself. It is an object of the present invention to provide a cowl side structure of the vehicle body, which enables to firmly mount the cowl cross bar.

상기와 같은 목적을 달성하기 위한 본 발명은,
사이드패널조합체의 프론트필라 외측부와 프론트필라인너패널의 전방 접합플랜지가 카울사이드어퍼아우터패널과 동일한 위치에 형성되어 상기 카울사이드어퍼아우터패널의 단부에 용접되고,

또한, 상기 프론트필라인너패널의 내측면 전방 모서리에 상기 카울탑패널의 단부와 카울탑보강패널의 단부에 대응되는 위치에 양단부가 용접되어 프론트필라의 내측에 평행사변형의 폐단면을 형성하는 프론트필라인너로워익스텐션이 설치된다.In addition, both ends are welded at positions corresponding to the ends of the cowl top panel and the ends of the cowl top reinforcement panel at the front edge of the inner surface of the front pillar liner panel to form a closed cross section of parallelogram inside the front pillar. Inner lower extension is installed.

그리고, 상기 프론트필라인너패널의 내측면 후방에는 상기 프론트필라인너패널의 외측면 후방에 양단이 용접된 카울크로스바마운팅브라켓과 대응되는 "역U자" 형상이면서 양단에 플랜지가 형성된 카울크로스바마운팅인너보강브라켓이 용접되고, 상기 프론트필라인너패널의 외측면과 상기 카울크로스바마운팅브라켓의 전방측면에 이들의 사이를 경사지게 연결하는 카울크로스바마운팅아우터보강브라켓이 용접된다.In addition, a rear cross-shaped cowl crossbar mounting inner reinforcement having a "reverse U-shaped" shape corresponding to both ends of the cowl crossbar mounting bracket welded at both ends to the rear side of the front side of the front fill liner panel and a flange formed at both ends thereof. The bracket is welded, and the cowl crossbar mounting outer reinforcement bracket is welded to the outer surface of the front fill liner panel and the front side of the cowl crossbar mounting bracket to be inclined therebetween.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 2는 카울사이드부와 프론트필라의 연결부를 다양한 각도에서 도시한 사시도들로서, 프론트필라인너패널(7)의 외측부에 용접되어 프론트필라를 구성하는 사이드패널조합체(5)의 프론트필라외측부(6)는 제외된 상태이며, 도 3의 이해를 돕기위해 도시하였다.FIG. 2 is a perspective view illustrating the connection portion between the cowl side portion and the front pillar from various angles, and the front pillar outer portion 6 of the side panel assembly 5 which is welded to the outer side of the front pillar liner panel 7 to form the front pillar. Is in an excluded state, and is shown to aid in understanding of FIG. 3.

상기 도 2 및 도 1의 대응도로서 도시된 도 3을 참조하면, 카울탑패널(1)과 카울탑보강패널(2) 및 카울사이드어퍼인너패널(3)의 용접부 위치가 모두 변경되었음을 알 수 있다.Referring to FIG. 3, which is shown as a correspondence diagram of FIGS. 2 and 1, it can be seen that the welded positions of the cowl top panel 1, the cowl top reinforcement panel 2, and the cowl upper inner panel 3 are all changed. have.

상기와 같이 구조를 변경하기 위해서 본 발명은 사이드패널조합체(5)의 구조변경을 필요로 한다.In order to change the structure as described above, the present invention requires a structure change of the side panel assembly 5.

즉, 도시된 바와 같이, 사이드패널조합체(5)를 구성하는 프론트필라인너패널(7)과 프론트필라외측부(6)의 전방측 접합플랜지가 차량의 실외측에 형성된다.That is, as shown, the front joining flange of the front pillar liner panel 7 and the front pillar outer portion 6 constituting the side panel assembly 5 is formed on the outdoor side of the vehicle.

즉, 사이드패널조합체(5)의 프론트필라외측부(6)가 실내쪽으로 절곡연장되지 않고 자신의 외측면 및 상기 카울사이드어퍼아우터패널(4)과 동일한 평면을 이루는 위치에 형성된다.That is, the front pillar outer portion 6 of the side panel assembly 5 is formed at a position forming the same plane as its outer surface and the cowl side outer panel 4 without being extended to the interior.

즉, 상기 프론트필라외측부(6)의 전방측 접합플랜지는 카울사이드어퍼아우터패널(4)과 동일한 평면상에 형성되어, 그 단부에 용접된다.That is, the front joining flange of the front pillar outer portion 6 is formed on the same plane as the cowl side outer panel 4 and welded to the end thereof.

한편, 상기와 같은 구조에 의하여 프론트필라인너패널(7)의 전방측 단부는 실외측으로 연장되어 상기 접합플랜지를 구성하게 되는바, 이에 의해 프론트필라인너패널(7)의 전방측면은 접합플랜지와 같은 돌출부가 존재하지 않는 평면으로 형성된다.On the other hand, according to the above structure, the front end of the front fill liner panel 7 extends to the outside to form the joining flange, whereby the front side of the front fill liner panel 7 is the same as the joining flange. It is formed into a plane in which no protrusions exist.

상기와 같이 돌출부 없는 평면으로 형성된 프론트필라인너패널(7)의 전방측면에 카울탑보강패널(2)의 단부가 연장되어 용접된다(P1,P2 지점). 이때 상기 카울탑보강패널(2)의 단부는 상기 프론트필라인너패널(7)의 전방측면 전체를 덮는 상태이다.As described above, the ends of the cowl top reinforcement panel 2 are extended and welded to the front side of the front fill liner panel 7 formed in a plane without protrusions (points P1 and P2). At this time, the end of the cowl top reinforcing panel (2) is in a state covering the entire front side of the front fill liner panel (7).

그리고, 상기 카울탑보강패널(2)과 평행한 상태로 소정 거리 이격되어 차실쪽으로 위치되는 카울탑패널(1)의 단부는 상기 프론트필라인너패널(7)의 실내측면에 용접된다(P3지점).
또한, 상기 프론트필라인너패널(7)의 전방측 모서리와 소정 거리 이격된 위치에 카울사이드어퍼인너패널(3)의 단부가 용접된다.In addition, the ends of the cowl top panel 1 which are spaced apart by a predetermined distance in parallel with the cowl top reinforcement panel 2 and are positioned toward the compartment are welded to the interior side of the front fill liner panel 7 (point P3). .
In addition, an end portion of the cowl upper inner panel 3 is welded at a position spaced apart from the front edge of the front fill liner panel 7 by a predetermined distance.

이와 같이 종래에 카울탑보강패널(2)과 카울사이드어퍼인너패널(3)이 카울탑패널(1)의 단부를 통해 프론트필라의 실내측 모서리부분에 연결되던 상태에서 카울탑패널(1)과 카울탑보강패널(2)이 각각 프론트필라의 실내측면과 전방측면에 용접됨으로써 용접점의 수가 3개 지점(P1,P2,P3)으로 증가됨은 물론, 카울탑패널(1)과 카울탑보강패널(2)이 서로 다른 면(프론트필라인너패널(7)의 전방측면과 실내측면)에 용접되어 프론트필라에 연결됨으로써 구조적으로 카울사이드부와 프론트필라의 연결강성이 향상된다.Thus, the cowl top reinforcing panel (2) and the cowl side upper inner panel (3) and the cowl top panel (1) in the state that was connected to the interior side of the front pillar through the end of the cowl top panel (1) The cowl top reinforcement panel 2 is welded to the interior and front sides of the front pillar, respectively, increasing the number of welding points to three points (P1, P2, P3), as well as the cowl top panel 1 and the cowl top reinforcement panel. (2) is welded to different surfaces (front side and interior side of the front pillar liner panel 7) and connected to the front pillar to structurally improve the connection rigidity between the cowl side and the front pillar.

따라서, 차량의 종축선을 중심으로 한 비틀림 강도도 향상된다.Therefore, the torsional strength around the longitudinal axis of the vehicle is also improved.

한편, 상기 프론트필라인너패널(7)의 내측면 전방모서리에는 이 모서리부와 더불어 폐단면을 형성하는 프론트필라인너로워익스텐션(9)이 설치된다.On the other hand, the front fill liner lower extension 9 is formed at the inner side front edge of the front fill liner panel 7 to form a closed cross section with this corner portion.

상기 프론트필라인너로워익스텐션(9)은 일종의 보강브라켓으로서, 단면이 "ㄱ"자 형상으로 형성된 몸체의 양단이 프론트필라인너패널(7)의 전방측면과 실내측면에 맞대어지는 플랜지로 형성되어 각각 프론트필라인너패널(7)의 상기 전방측면과 실내측면에 용접된다.The front fill line lower extension 9 is a kind of reinforcing bracket, and both ends of the body having a cross section having a "A" shape are formed by flanges which face the front side and the interior side of the front fill liner panel 7, respectively. The front side and the interior side of the fill liner panel 7 are welded.

상기 프론트필라인너로워익스텐션(9)은 프론트필라 자체의 강성을 향상시키고, 이에 의해 프론트필라에 의한 카울탑패널(1)과 카울탑보강패널(2)의 지지강성을 향상시킨다.The front pillar line lower extension 9 improves the rigidity of the front pillar itself, thereby improving the supporting rigidity of the cowl top panel 1 and the cowl top reinforcing panel 2 by the front pillar.

따라서, 차체의 비틀림 강성은 더욱 보강된다.Therefore, the torsional rigidity of the vehicle body is further reinforced.

또한, 상기 프론트필라인너로워익스텐션(9)에 의해 차체의 횡방향 구조물인 상기 카울탑패널(1)과 카울탑보강패널(2)의 단면구조(폐단면 형상)가 프론트필라의 내측부까지 연장되게 되므로 횡강성이 향상되어 측면 충돌시 안전성이 향상된다.In addition, the front pillar line lower extension 9 extends the cross-sectional structure (closed cross-sectional shape) of the cowl top panel 1 and the cowl top reinforcement panel 2, which are lateral structures of the vehicle body, to the inner side of the front pillar. Therefore, the lateral stiffness is improved, which improves the safety during side impact.

한편, 상기 프론트필라인너패널(7)의 내측면 후방에는 외측면에 장착되어 있는 카울크로스바마운팅브라켓(8)에 대응되는 형상의 카울크로스바마운팅인너보강브라켓(10)이 구비된다.Meanwhile, the cowl crossbar mounting inner reinforcing bracket 10 having a shape corresponding to the cowl crossbar mounting bracket 8 mounted on the outer side is provided at the rear of the inner side of the front fill liner panel 7.

상기 카울크로스바마운팅인너보강브라켓(10)은 단면이 역 "U"자 형상으로 형성되고 양단에 플랜지가 절곡성형된 것으로, 상기 카울크로스바마운팅브라켓(8)의 양단 플랜지가 용접되는 위치와 동일한 위치의 프론트필라인너패널(7) 내측면상에 용접되되, 실외측면이 상기 프론트필라외측부(6)에 맞대어지는 구조로 장착된다.The cowl crossbar mounting inner reinforcing bracket 10 is formed in an inverted "U" shape in cross section and is bent at both ends of the cowl crossbar mounting bracket, and has the same position as that at which both flanges of the cowl crossbar mounting bracket 8 are welded. The front pillar liner panel 7 is welded on the inner side, and the outdoor side is mounted to the front pillar outer side 6.
