본 고안은 자동차용 센터필라의 내부설치구조에 관한 것으로, 더욱 상세하게는 센터필라의 하부내측에 소정 형태의 가로보강재와 세로보강재를 설치하여 외부측면에서 가해지는 충격에너지를 보다 효율적으로 흡수가능하게 하고, 더 나아가서는 승차자의 안전에 기여하게 하는 자동차용 센터필라의 내부설치구조에 관한 것이다.The present invention relates to an internal installation structure of a center pillar for an automobile, and more particularly, to install a horizontal reinforcement member and a vertical reinforcement member in a lower inner side of the center pillar to more efficiently absorb impact energy applied from an outer side surface. In addition, the present invention relates to an internal installation structure of a vehicle center pillar that contributes to the safety of a passenger.

종래의 센터필라의 내부설치구조를 첨부도면 제1도와 제2도에서 설명하면, 하부에 일정형태의 완곡부(10)와 절곡부(12)가 형성된 외측센터필라(14)와, 상기 외측센터필라(14)의 후면에 접설되는 길이방향의 보조보강재(16)와, 상기 외측센터필라(14)의 절곡부(12) 내면에 고정설치되는 내측센터필라(18)와, 외측센터필라(14)와 내측센터필라(18)를 동시에 지지하는 씰(Sill)(20)로 구성되어 있다.Referring to FIG. 1 and FIG. 2 of the attached inner pillar structure of the conventional center pillar, an outer center pillar 14 having a curved portion 10 and a bent portion 12 having a predetermined shape is formed on the lower portion of the center pillar and the outer center. Auxiliary reinforcement material in the longitudinal direction which is connected to the rear of the pillar 14, the inner center pillar 18 fixed to the inner surface of the bent portion 12 of the outer center pillar 14, and the outer center pillar 14 ) And a seal 20 for simultaneously supporting the inner center pillar 18.

그러나, 상기에서와 같은 종래 센터필라의 내부설치구조는 외측센터필라(14)와 그 후면에 설치되는 보조보강재(16)가 모두 수직재이기 때문에 실질적으로 수평으로 가해지는 충격에너지에 대해서는 전혀 대응하지 못하였고, 그에 따라 1차로 외측센터필라(14)에 가해진 충격에너지가 내측센터필라(18)로 2차 전달될 때 그 충격에너지는 전혀 감쇠되지 않은 상태로 전해지기 때문에 승차자의 상해정도나 자동차 측면의 변형정도가 심하게 되는 문제점이 있었다.However, the inner installation structure of the conventional center pillar as described above does not correspond to the impact energy applied substantially horizontally because both the outer center pillar 14 and the auxiliary reinforcement 16 installed on the rear thereof are vertical members. Accordingly, when the impact energy applied to the outer center pillar 14 is first transmitted to the inner center pillar 18 secondly, the impact energy is transmitted without being attenuated at all. There was a problem that the degree of deformation is severe.

이에 본 고안은 상술한 바와 같은 종래의 제반문제를 감안하여 안출된 것으로, 그 목적은 센터필라의 하부내측에 소정 형태의 세로보강재와 가로보강재를 설치하여 자동차의 측면의 변형 보강은 몰론 외부측면에서 가해지는 충격에너지를 보다 효율적으로 흡수하게 하고, 더 나아가서는 승차자의 안전에 기여하게 하는 자동차용 센터필라의 설치구조를 제공함에 있다.The present invention has been devised in view of the conventional problems as described above, and its purpose is to install a longitudinal reinforcement and a transverse reinforcement of a certain type in the lower inner side of the center pillar, so that the deformation reinforcement of the side of the vehicle is at the outside of the molon. The present invention provides an installation structure of a center pillar for automobiles that more efficiently absorbs impact energy to be applied and further contributes to the safety of passengers.

상기한 목적을 달성하기 위해 본 고안은 외측센터필라와, 보조보강재 내측센터필라 및 씰로 이루어진 자동차의 센터필라에 있어서, 상기 내측센터필라의 하부로부터 외측센터필라의 절곡부(12)에 이르기까지 연설되는 상기 세로보강재의 상부로부터 외측센터필라에 접설되는 보조보강재의 하부에 이르기까지 가로보강재를 설치하되, 그 가로보강재의 중간부는 외부 충격시 절첩되게 절곡 형성된 특징으로 갖는다.In order to achieve the above object, the present invention is a center pillar of an automobile consisting of an outer center pillar, an auxiliary reinforcement inner center pillar, and a seal, from a lower portion of the inner center pillar to a bent portion 12 of the outer center pillar. The horizontal reinforcement is installed from the upper portion of the longitudinal reinforcement to the lower portion of the auxiliary reinforcement which is in contact with the outer center pillar, the middle portion of the transverse reinforcement is characterized by being folded to be folded at the time of external impact.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

제3도는 제1도의 A부분에 대한 본 고안의 측단면도로서, 하부에 일정형태의 완곡부(10)와 절곡부(12)가 형성된 외측센터필라(14)와, 상기 외측센터필라(14)의 후면에 접설되는 길이방향의 보조보강재(16)와, 상기 외측센터필라(14)의 절곡부(12) 내면에 고정설치되는 내측센터필라(18)와, 외측센터필라(14)와 내측센터필라(18)를 동시에 지지하는 씰(20)로 구성된 센터필라의 내부설치구조에 있어서, 내측센터필라(18)의 내측으로부터 외측센터필라(14)의 절곡부(12) 내측에 이르기까지 일정형태의 벤딩부와 경사부가 형성된 세로보강재(22)를 열압착 또는 용접하고, 상기 세로보강재(22)의 상부일측으로부터 외측센터필라(14)에 접설되는 보조보강재(16)의 하부에 이르기까지 가로보강재(24)를 열압착 또는 용접으로 고정하되, 상기 가로보강재(24)의 양측끝단을 서로 엇갈리게 절곡하여 고정한 것이다.3 is a side cross-sectional view of the present invention for the portion A of FIG. 1, the outer center pillar 14 and the outer center pillar 14 having a curved portion 10 and a bent portion 12 formed in a lower portion thereof, and the outer center pillar 14. Auxiliary reinforcement in the longitudinal direction of the rear side of the reinforcement 16, the inner center pillar 18 is fixed to the inner surface of the bent portion 12 of the outer center pillar 14, the outer center pillar 14 and the inner center In the internal installation structure of the center pillar which consists of the seal 20 which simultaneously supports the pillar 18, the predetermined shape from the inside of the inner center pillar 18 to the inside of the bent part 12 of the outer center pillar 14 is carried out. The longitudinal stiffener 22 is formed by bending and inclined portion of the longitudinal reinforcement 22, the horizontal stiffener from the upper side of the longitudinal stiffener 22 to the lower portion of the auxiliary stiffener 16 which is connected to the outer center pillar (14) (24) is fixed by thermocompression or welding, and both ends of the transverse reinforcing material (24) stand It is fixed to the bent staggering.

이와 같이 구성된 본 고안을 조립설치하는 과정을 살펴보면, 내측센터필라(18)와 내측면이 보조보강재(16)가 접설된 외측센터필라(14)를 구비한 상태에서 먼저, 내측센터필라(18)의 내측하단부로부터 외측센터필라(14)의 완곡부(10)가 끝나는 부분 즉, 절곡부(12)에 이르기까지 벤딩부와 경사부가 형성된 세로보강재(22)를 서로 접하게하여 융착하고, 그 다음으로는 내측센터필라(18)의 내측하단부로부터 설치되는 세로보강재(22)의 상부와 외측센터필라(14)와 접설되는 보조보강재(16)의 하부에 가로보강재(24)가 설치되는 폭에 맞게 설치면을 절곡하여 상기와 같이 융착한 후, 마지막으로 내측센터필라(18)의 외측하단부로부터 외측센터필라(14)의 단부에 이르기까지 씰(20) 접착시켜 상기 외측센터필라(14)와 내측센터필라(18)를지지 고정하면 되는 것이다.Looking at the process of assembling and installing the present invention configured as described above, the inner center pillar (18) and the inner surface is the first center inner pillar (18) in the state provided with the outer center pillar (14) in which the auxiliary reinforcing material 16 is folded. From the inner lower end of the outer center pillar 14 to the end of the bent portion 10 of the outer center pillar 14, that is, to the bent portion 12, the longitudinal reinforcement 22 formed with the bent portion and the inclined portion is brought into contact with each other and then fused. Is installed in accordance with the width of the horizontal reinforcing material 24 is installed in the upper portion of the vertical reinforcing material 22 is installed from the inner lower end of the inner center pillar 18 and the lower portion of the auxiliary reinforcing material 16 which is in contact with the outer center pillar (14). After the surface is bent and fused as described above, the seal 20 is finally glued from the lower end of the inner center pillar 18 to the end of the outer center pillar 14, thereby adhering the outer center pillar 14 and the inner center. What is necessary is to support and fix the pillar 18.

이와 같은 본 고안을 적용하게 되면, 자동차의 측면부를 이루는 사이드패널의 수직 하중에 의한 변형을 효율적으로 보강하며, 자동차의 측면 접촉시 외부로부터 가해오는 충격에너지를 가로 보강재가 흡수하여 지지하며, 더 나아가서는 큰 충격에 대해서 가로보강재의 절곡부위가 절첩되면서 외부의 충격을 흡수하여 승차자에게 직접적인 충격을 가하지 않도록 하는 효과를 얻는다.When the present invention is applied, it effectively reinforces the deformation caused by the vertical load of the side panel forming the side part of the vehicle, and the horizontal reinforcement absorbs and supports the impact energy applied from the outside during the side contact of the vehicle, and furthermore, As the bending part of the transverse stiffener is folded against the large impact, the external shock is absorbed to prevent direct impact on the occupant.
