And a front side member furnace (4) coupled to the subframe through the subframe mounting bracket (3), and a combination of a structural foam member and a steel plate and along the shape of the front side member carrier (4). A reinforcement member is formed to be accommodated in the front side membrane air 4 and is coupled to the assembly of the dash panel 1 and the center floor panel 2 and overlaps with the flange 4a of the front side membrane air 4. It is a structure comprised by the assembly 20.
여기서, 상기 보강부재어셈블리(20)는 도 4와 도 5에 도시된 바와 같이, 상기 대시패널(1)과 센터플로어패널(2)의 연결부 형상을 따라 미음자(ㅁ)의 종단면 모양을 갖도록 소정길이로 형성되는 상단구조발포재(21)와, 이 상단구조발포재(21)와 중첩되어 결합되면서 상기 대시패널(1)과 센터플로어패널(2)의 조립체의 밑면에 덧대어져 결합되도록 테두리부에 플랜지(22a)가 형성된 제1보강패널부재(22)와, 이 제1보강패널부재(22)의 플랜지(22a) 및 프런트사이드멤버리어로어(4)의 플랜지(4a)와 접합되는 플랜지(23a)를 구비하면서 상기 프런트사이드멤버리어로어(4)의 형상을 따라 디귿자(ㄷ)의 종단면 모양을 갖도록 형성되는 제2보강패널부재(23)와, 이 제2보강패널부재(23)의 바깥면에 덧대어져 결합되면서 상기 프런트사이드멤버리어로어(4)의 안쪽면과 덧대어져 결합되는 하단구조발포재(24)로 구성된다.As shown in FIGS. 4 and 5, the reinforcing member assembly 20 has a predetermined length so as to have a longitudinal cross-sectional shape of the microphone (ㅁ) along the shape of the connection portion between the dash panel 1 and the center floor panel 2. The upper structure foam member 21 is formed to be overlapped with the upper structure foam member 21 while being joined to the bottom of the assembly of the assembly of the dash panel 1 and the center floor panel (2) to the rim portion A flange 23a joined to the first reinforcement panel member 22 having the flange 22a formed thereon, the flange 22a of the first reinforcement panel member 22 and the flange 4a of the front side membrane gear 4. And a second reinforcement panel member 23 formed along the shape of the front side membrane language 4 to have a longitudinal cross-sectional shape of the recess (c), and an outer surface of the second reinforcement panel member 23. It is padded with and padded with the inner surface of the front side membrane air (4) The bottom structure comprises a foam material (24).
한편, 상기에 전술한 상단구조발포재(21; upper structural form)와 하단구조발포재(24; lower structural form)는 에폭시계 수지(epoxy resin)를 이용하여 성형되는 보강부재로서, 상기 상단구조발포재(21)와 하단구조발포재(24)는 전착도장 공정중에 경화, 발포되면서 제1,2보강패널부재(22,23)와 접착되어 보강부재어셈블리(20)를 구성하게 된다.Meanwhile, the upper structural foam member 21 and the lower structural foam member 24 described above are reinforcing members formed by using an epoxy resin, and the upper structural foam member is formed. The ash 21 and the lower structure foam member 24 are hardened and foamed during the electrodeposition coating process, and are then bonded to the first and second reinforcement panel members 22 and 23 to form the reinforcing member assembly 20.
이와 같이, 구조발포재(structural form)를 이용하여 구성되는 제품은 구조발포재의 특성상 고강성과 저비중 및 강력한 접착력을 가지게 되며 이로 인해 현재는 비교적 고가의 고급사양 차종에만 선택적으로 적용되고 있는 실정이다.As such, the product formed by using the structural foam (structural form) has a high stiffness, low specific gravity and strong adhesive force in the characteristics of the structural foam material, which is currently being selectively applied only to relatively expensive high-end models.
따라서, 작업자가 에폭시계 수지(epoxy resin)를 이용하여 상단구조발포재(21)와 하단구조발포재(24)를 성형한 다음 도 4와 도 5에 도시된 바와 같이 상단구조발포재(21)와 제1보강패널부재(22)를 서로 중첩시켜 중첩된 부위를 용접결합시키고, 상기 하단구조발포재(24)의 안쪽으로 제2보강패널부재(23)를 삽입하여 서로 용접결합시킨 다음, 상기 상단구조발포재(21)와 결합된 제1보강패널부재(22)의 플랜지(22a)를 상기 하단구조발포재(24)와 결합된 제2보강패널부재(23)의 플랜지(23a)와 도 6과 도 7에 도시된 바와 같이 서로 중첩시켜 용접결합시키게 되면, 본 발명에 따라 프런트사이드멤버리어로어부를 구성하는 보강부재어셈블리(20)가 제작되게 된다.Therefore, the operator molds the upper structural foam member 21 and the lower structural foam member 24 using an epoxy resin and then the upper structural foam member 21 as shown in FIGS. 4 and 5. And the first reinforcement panel member 22 overlap each other to weld the overlapped portions, and the second reinforcement panel member 23 is inserted into the lower structure foam member 24 to be welded to each other. The flange 22a of the first reinforcement panel member 22 coupled with the upper structural foam member 21 is illustrated with the flange 23a of the second reinforcement panel member 23 coupled with the lower structural foam member 24. 6 and 7, as shown in Figure 6 overlapping each other and welded, the reinforcing member assembly 20 constituting the front portion of the membrane portion according to the present invention is produced.
그리고, 작업자는 제작이 완료된 상기 보강부재어셈블리(20)를 도 2와 도 3에 도시된 바와 같이 대시패널(1)과 센터플로어패널(2)의 조립체 및 프런트사이드멤버리어로어(4)사이에 위치시킨 다음, 상기 대시패널(1)과 센터플로어패널(2)의 조립체의 밑면과 상기 제1보강패널부재(22)의 플랜지(22a)와 상기 제2보강패널부재(23)의 플랜지(23a) 및 상기 프런트사이드멤버리어로어(4)의 플랜지(4a)를 도 8과 도 9에 도시된 바와 같이 서로 서로 중첩시켜 용접결합시키게 되면 본 발명에 따른 프런트사이드멤버리어로어부의 구성이 완료되게 되고, 이후 본 발명에 따른 프런트사이드멤버리어로어부가 조립된 차체가 전착도장 공정중에 발포성형됨으로써 완전한 조립이 이루어지게 된다.Then, the operator is completed between the assembly of the dash panel (1) and the center floor panel (2) and the front side member chamber (4) as shown in Figure 2 and 3, the manufacturing is completed After positioning, the bottom surface of the assembly of the dash panel 1 and the center floor panel 2, the flange 22a of the first reinforcement panel member 22 and the flange 23a of the second reinforcement panel member 23 ) And the flanges 4a of the front side member membrane air 4 are overlapped with each other as shown in FIGS. 8 and 9 to be welded to each other to complete the construction of the front side member membrane air portion according to the present invention. Subsequently, the vehicle body assembled with the front side member according to the present invention is foamed during the electrodeposition coating process, thereby achieving complete assembly.
이와 같이, 대시패널(1)과 센터플로어패널(2)의 조립체 및 프런트사이드멤버리어로어(4)와 함께 프런트사이드멤버리어로어부를 구성하는 보강부재어셈블리(20)가 에폭시계 수지를 이용하여 성형되는 상하단구조발포재(21,24) 및 소정의 두께를 갖는 제1,2보강패널부재(22,23)의 결합체로 이루어지게 되면, 도 1을 참조로 전술한 바와 같이 리어로어린포스먼트(5) 및 다수개의 보강패널들(6,7,8,9)의 결합으로 이루어지는 종래의 프런트사이드멤버리어로어부의 구조보다 부품수의 절감효과를 기대할 수 있게 된다.In this way, the assembly of the dash panel 1 and the center floor panel 2 and the reinforcing member assembly 20 constituting the front side membrane unit together with the front side membrane unit 4 are made of epoxy resin. When the upper and lower structural foam members 21 and 24 to be molded and the combination of the first and second reinforcement panel members 22 and 23 having a predetermined thickness are formed, as described above with reference to FIG. It is possible to expect the effect of reducing the number of parts than the structure of the conventional front side member by using the combination of (5) and a plurality of reinforcement panels (6, 7, 8, 9).
또한, 종래의 리어로어린포스먼트(5) 및 다수개의 보강패널들(6,7,8,9)은 모두 두꺼운 강판(steel)으로 이루어지는 것에 비해, 본 발명에 따른 보강부재어셈블리(20)는 강판과 비교하여 볼 때 비교적 중량이 적게 나가는 구조발포재를 강판을 사용하는 일부 부품 대신에 사용함으로써, 전체적인 차체의 중량을 감소시킬 수가있게 되고 이로 인해 차량의 연비도 향상시킬 수가 있게 되며, 아울러 제조원가도 그만큼 절감시킬 수 있는 효과를 기대할 수 있게 된다.In addition, the conventional lower rear forcement 5 and the plurality of reinforcement panels 6, 7, 8, and 9 are all made of thick steel, the reinforcing member assembly 20 according to the present invention is By using a structural foam material, which is relatively lighter than steel sheet, in place of some parts using steel sheets, it is possible to reduce the weight of the entire vehicle body, thereby improving fuel economy of the vehicle. You can expect the effect to save even that much.
이상 설명한 바와 같이 본 발명에 의하면, 대시패널 및 센터플로어패널의 조립체와 프런트사이드멤버리어로어와 함께 프런트사이드멤버리어로어부를 구성하는 보강부재어셈블리가 에폭시계 수지를 이용하여 성형되는 상하단구조발포재 및 소정의 두께를 갖는 제1,2보강패널부재의 결합체로 이루어져, 프런트사이드멤버리어로어부의 부품수가 절감되고 이로 인해 전체적인 차체의 중량이 감소되며 아울러 차량의 연비가 향상되면서 제조원가가 절감되는 효과가 있게 된다.As described above, according to the present invention, the upper and lower structure foam members in which the reinforcing member assembly constituting the front side member unit together with the assembly of the dash panel and the center floor panel and the front side member unit are formed by using an epoxy resin. And a combination of the first and second reinforcement panel members having a predetermined thickness, thereby reducing the number of parts in the front side member, thereby reducing the weight of the entire vehicle body and improving fuel efficiency of the vehicle, thereby reducing manufacturing costs. Will be.
