본 발명은 차량의 측면충돌이나 정면충돌시 차체의 강성을 증가시키는 자동차용 크로스멤버의 차체구조에 관한 것으로서, 더욱 상세하게는 프런트프레임과 결합하는 크로스멤버의 구조를 개선하여 정면충돌성능과 측면충돌성능을 향상시키고 부품수를 축소하여 조립공정 및 생산성을 향상시켜 저가의 차량을 개발하도록 하는 자동차용 크로스멤버의 차체구조에 관한 것이다.The present invention relates to a vehicle structure of a cross member for a vehicle that increases the rigidity of the vehicle body in the event of a side collision or a front collision of the vehicle. More specifically, the front collision performance and side collision are improved by improving the structure of the cross member coupled to the front frame. The present invention relates to a vehicle structure of a cross member for automobiles that improves performance, reduces parts, and improves the assembly process and productivity to develop a low-cost vehicle.
일반적으로 크로스멤버는 사이드멤버, 언더보디등에 쓰여지고 있는 골격으로 차체의 강도나 강성을 높이기 위하여 쓰여지고 있고 전,후나 좌,우방향의 휘어짐을 방지하기 위하여 쓰이고 있으며 자동차의 진행방향에 대하여 직각으로 프런트프레임에 설치되어 있다.In general, crossmembers are used to increase the strength and rigidity of the body, and are used to prevent bending in the front, rear, left, and right directions. The front frame is perpendicular to the direction of the vehicle. Installed in
이와 같이 차체의 프런트프레임에 취부되어 차체의 강성을 증가시키기 위한 종래 크로스멤버의 취부구조를 첨부된 도면에 의거하여 설명하면 다음과 같다.As described above with reference to the accompanying drawings, the mounting structure of the conventional cross member for mounting on the front frame of the vehicle body to increase the rigidity of the vehicle body is as follows.
도 1은 종래 크로스멤버의 취부구조를 보인 요부사시도이고, 도 2는 종래 크로스멤버의 구조를 보인 요부단면도로서, 차체(1)의 프런트프레임(10) 전면으로 라디에이터와 냉각 팬을 감싸는 슈라이드판넬(30)의 후면부에 접착되어 보조프레임(40)이 결합설치되어 있고 상기 슈라이드판넬(30)의 전면부와 접착되어 전면판체(21)와 후면판체(22)로 이루어져 내부로 폐단면을 이루도록 커버(23)가 설치되어 있는 크로스멤버(20)의 후면판체가 프런트프레임(10)에 직각방향으로 결합설치되어 있다.1 is a main part perspective view showing the mounting structure of the conventional cross member, Figure 2 is a main cross-sectional view showing the structure of the conventional cross member, the shroud panel surrounding the radiator and the cooling fan to the front of the front frame 10 of the vehicle body (1) Auxiliary frame 40 is bonded to the rear portion of the 30 is installed and bonded to the front portion of the shroud panel 30 is composed of the front plate body 21 and the rear plate body 22 to form a closed cross section inside The rear plate body of the cross member 20, in which the cover 23 is installed, is coupled to the front frame 10 at right angles.
따라서 종래의 크로스멤버(20)의 차체구조는 프런트프레임(10)과 보조프레임(40)이 차체의 강성을 유지하는 주요한 부분으로 슈라우드판넬(30)의 후면부를 보조프레임(40)에 접착한 후 프런트프레임(10)의 전단부로 크로스멤버(20)의 후면판체(22)를 결합설치하는 구조로 이루어져 있어 차량의 측면충돌이나 정면충돌시 차체의 강성에 불리하고 부품수의 과다로 인하여 제작, 조립, 물류등의 생산성을 저하시키는 문제점이 있었다.Therefore, the body structure of the conventional cross member 20 is a main portion of the front frame 10 and the auxiliary frame 40 to maintain the rigidity of the vehicle body after attaching the rear portion of the shroud panel 30 to the auxiliary frame 40 It is composed of the structure that combines and installs the rear plate body 22 of the cross member 20 as the front end of the front frame 10, which is disadvantageous to the rigidity of the vehicle body in the case of side collision or frontal collision of the vehicle and manufactured and assembled due to the excessive number of parts. There was a problem of lowering productivity, such as logistics.
본 발명은 이와 같은 문제점을 개선하기 위하여 발명한 것으로서, 본 발명의 목적은 차체의 프런트프레임의 하측부로 삽입부를 형성하고 상기의 삽입부에 안내되어 하측부로 개구부를 형성하고 플랜지부의 양측끝단으로 가이드홀을 형성한 일체형의 크로스멤버를 결합설치하여 차량의 정면 및 측면충돌시 크로스멤버가 프런트프레임의 내부에 위치되어 밀착함으로서 차체의 강성을 증가시키고 부품수의 축소로 차체의 중량을 감소시킬 뿐만 아니라 조립성 및 성형성 향상과 작업공정의 축소를 통해 저가의 차량을 개발하도록 하는 자동차용 크로스멤버의 차체구조를 제공하는데 있다.The present invention has been invented to solve such a problem, and an object of the present invention is to form an insertion portion in the lower portion of the front frame of the vehicle body and guide the insertion portion to form an opening in the lower portion and guide to both ends of the flange portion. By integrating and installing an integrated cross member that forms a hole, when the front and side collisions of the vehicle are carried out, the cross members are located inside the front frame so that the rigidity of the body is increased and the weight of the body is reduced by reducing the number of parts. It is to provide a vehicle structure of a cross member for automobiles to develop low-cost vehicles by improving assembly and formability and reducing work processes.

도 3은 본 발명인 크로스멤버의 구조를 보인 단면도이고, 도 4는 본 발명에 의한 프런트프레임과 휠에이프런의 결합구조를 보인 요부단면도이며, 도 5는 본 발명의 결합구조를 보인 요부단면도로서, 차체의 프런트프레임(100)의 하측부로 삽입부(110)를 형성하고 상기의 삽입부(110)에 안내되어 하측부로 개구부(210)를 형성하고 플랜지부의 양측끝단으로 가이드홀(220),(220a)을 형성한 일체형의 크로스멤버(200)를 결합설치하는 것을 구성상의 특징으로 한다.Figure 3 is a cross-sectional view showing the structure of the cross member of the present invention, Figure 4 is a main sectional view showing a coupling structure of the front frame and the wheel apron according to the present invention, Figure 5 is a main sectional view showing a coupling structure of the present invention, the vehicle body The insertion unit 110 is formed at the lower portion of the front frame 100 of the front frame 100 and is guided to the insertion unit 110 to form the opening 210 at the lower portion, and guide holes 220 and 220a at both ends of the flange portion. It is characterized by the configuration of the coupling member formed integrally formed cross member 200).
또한 프런트프레임(100)은 휠에이프런(300)의 외측면(310)에 이중 스폿용접에 의해 결합설치한다.In addition, the front frame 100 is coupled to the outer surface 310 of the wheel apron 300 by double spot welding.
이와 같이 본 발명은 프론트프레임(100)의 삽입부(110)로 크로스멤버(200)를 삽입하고 프론트프레임(100)의 양측끝단이 크로스멤버(200)의 가이드홀(220),(220a)에 안착되도록 하여 결합하고 프론트프레임(100)은 휠에이프런(300)의 외측면(310)으로 이중 스폿용접에 의해 결합설치함으로서 차량의 정면 및 측면충돌시 크로스멤버(200)가 프런트프레임(100)에 밀착되어 차체의 강성을 증가시킨다.As such, the present invention inserts the cross member 200 into the insertion unit 110 of the front frame 100 and both ends of the front frame 100 are guide holes 220 and 220a of the cross member 200. The front frame 100 is coupled to be seated, and the front frame 100 is coupled to the outer surface 310 of the wheel apron 300 by double spot welding so that the cross member 200 is connected to the front frame 100 at the front and side collision of the vehicle. Close contact increases the rigidity of the car body.
또한 프런트프레임(100)이 휠에이프런(300)의 외측면(310)으로 이중 스폿용접에 의하여 결합설치되어 있어 차체의 측면충돌성능을 향상시키고 크로스멤버(200)를 일체형으로 형성하여 부품수의 축소로 차체의 중량을 감소시킬 뿐만 아니라 조립성 및 성형성 향상과 작업공정의 축소를 통해 저가의 차량을 개발하도록 한 것이다.In addition, the front frame 100 is coupled to the outer surface 310 of the wheel apron 300 by double spot welding, thereby improving the side impact performance of the vehicle body and reducing the number of parts by integrally forming the cross member 200. In addition to reducing the weight of the car body, the development of low-cost vehicles through the improvement of assembly and formability and reduction of the work process was made.
이상과 같이 이루어지는 본 발명은 프런트프레임과 결합하는 크로스멤버의 구조를 개선하여 차량의 정면 및 측면충돌성능을 향상시키고 부품수를 축소하여 조립성 및 성형성의 향상과 작업공정의 축소를 통하여 저가의 차량을 개발하도록 하는 매우 유용한 발명이다.The present invention made as described above improves the structure of the cross member coupled to the front frame to improve the front and side collision performance of the vehicle, reduce the number of parts to improve the assembly and formability and reduce the work process of low-cost vehicles It is a very useful invention to develop.
