It is a reinforcement structure of the center pillar portion of the vehicle, characterized in that the outer panel is installed.
이하, 본 발명의 기술구성을 첨부된 도면에 의거하여 보다 상세하게 설명한다.Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.
도3은 본 발명에 따른 센터필라부를 나타낸 자동차의 측면도이고, 도4는 도3의 B-B 부위에 해당하는 본 발명의 센터필라부 보강구조를 나타낸 단면도이다.Figure 3 is a side view of the vehicle showing the center pillar portion according to the present invention, Figure 4 is a cross-sectional view showing the center pillar portion reinforcement structure of the present invention corresponding to the B-B portion of FIG.
먼저 도시된 도3에서 보면, 자동차를 측면에서 바라볼 경우 앞에서부터 순서대로 프론트필라(a), 센터필라(b), 리어필라(c)라고 하고, 상기 프론트필라(a), 센터필라(b), 리어필라(c)는 A필라, B필라, C필라라고도 한다.Referring to FIG. 3, the front pillar (a), the center pillar (b), and the rear pillar (c) are sequentially called from the front when viewed from the side of the vehicle, and the front pillar (a) and the center pillar (b). ), The rear pillar (c) is also called A pillar, B pillar, C pillar.
상기 프론트필라(a), 센터필라(b) 및 리어필라(c)는 루프(1)를 지지하고 차체 강도의 일부를 담당하고 있는 일종의 지주(支柱)로서, 특히 센터필라(b)는 측면 충돌시 가해지는 외력으로부터 탑승자의 흉부를 보호하는 중요한 기능을 담당하게 된다.The front pillar (a), the center pillar (b) and the rear pillar (c) are a kind of struts supporting the loop 1 and in charge of part of the vehicle body strength, in particular the center pillar (b) is a side impact It will play an important role in protecting the occupant's chest from external forces.
따라서, 본 발명은 상기 센터필라부(b)가 외력에 대해 최소한으로 변형되도록 센터필라부를 보강하는 구조이다.Therefore, the present invention is a structure for reinforcing the center pillar portion so that the center pillar portion b is deformed to the minimum with respect to the external force.
이하, 본 발명의 센터필라부 보강구조를 설명하면, 자동차의 측면부를 지지하기 위하여 루프(1)에서 차체하부(2)로 수직하게 설치되는 센터필라아웃터패널(10)에는 차체 외측으로 돌출되게 절곡된 돌출부(11)가 형성된다.Hereinafter, describing the center pillar reinforcing structure of the present invention, the center pillar outer panel 10 installed vertically from the roof 1 to the lower body 2 in order to support the side portion of the vehicle is bent to protrude out of the vehicle body. Protruded portions 11 are formed.
상기 센터필라아웃터패널(10)이 절곡 형성되고 또한 차체 외측으로 돌출되는 것은 센터필라아웃터패널(10)의 단면계수를 크게 하여 면 강성을 증대시키기 위함이다. 이렇게 센터필라아웃터패널(10)을 절곡시켜 단면계수를 크게 하면 패널의 자체 강성이 증대되며, 또한, 센터필라아웃터패널(10)에 차체 외측으로 돌출되는 돌출부(11)가 형성되도록 하면 외측에서 가해지는 외력에 좀 더 강하게 견딜 수 있게 된다.The center pillar outer panel 10 is bent and protruded to the outside of the vehicle body in order to increase the surface stiffness by increasing the cross-sectional coefficient of the center pillar outer panel 10. When the center pillar outer panel 10 is bent to increase the cross-sectional coefficient, the panel's own rigidity is increased, and when the center pillar outer panel 10 is formed with a protrusion 11 protruding to the outside of the vehicle body, it is applied from the outside. It will be able to withstand more external forces.
한편, 상기 센터필라아웃터패널의 돌출부(11)를 보강하기 위하여 상기 돌출부(11)에는 보강부재(20)가 설치되는데, 상기 보강부재(20)는 돌출부(11)와의 사이에 소정의 내부공간이 형성되도록 설치된다. 즉, 도4에 도시된 바와 같이 보강부재(20)와 돌출부(11)는 폐단면을 갖도록 결합되어 그 폐단면에 의해 형성되는 내부공간이 외력에 대해 변형되면서 충격흡수가 이루어지게 된다.On the other hand, the reinforcing member 20 is installed in the protrusion 11 to reinforce the protrusion 11 of the center pillar outer panel, the reinforcing member 20 has a predetermined internal space between the protrusion 11 It is installed to form. That is, as shown in FIG. 4, the reinforcing member 20 and the protrusion 11 are coupled to have a closed cross section, and the internal space formed by the closed cross section is deformed with respect to external force, thereby absorbing shock.
또한, 상기 보강부재(20)와 돌출부(11)간에 형성되는 내부공간에는 상기 보강부재(20)를 추가로 보강하기 위한 별도의 보조보강부재(21)가 설치된다.In addition, a separate auxiliary reinforcing member 21 for additionally reinforcing the reinforcing member 20 is installed in the inner space formed between the reinforcing member 20 and the protrusion 11.
또한, 상기 센터필라아웃터패널(10)의 일측에는 상기 돌출부(11)와 보강부재(20)를 차체 외측으로부터 커버하는 사이드아웃터패널(12)이 설치된다.In addition, one side of the center pillar outer panel 10 is provided with a side outer panel 12 for covering the protrusion 11 and the reinforcing member 20 from the outside of the vehicle body.
따라서, 상기 센터필라아웃터패널의 돌출부(11)에 외력이 가해지면 상기 보강부재(20)와 보조보강부재(21)가 변형되면서 상기 돌출부(11)에 가해진 충격력을 흡수하게 되며, 상기 돌출부(11)는 상기 보강부재(20)와 보조보강부재(21)에 의하여 변형되지 아니하고 버티게 되어 탑승자를 보호하게 되는 것이다.Therefore, when an external force is applied to the protrusion 11 of the center pillar outer panel, the reinforcing member 20 and the auxiliary reinforcing member 21 are deformed to absorb the impact force applied to the protrusion 11 and the protrusion 11 ) Is not deformed by the reinforcing member 20 and the auxiliary reinforcing member 21 is to protect the occupants.
상술한 바와 같이 본 발명에 따른 자동차의 센터필라부 보강구조에 의하면, 센터필라부에 충격이 가해지면 그 충격력을 센터필라아웃터패널에 설치된 두 개의 보강부재가 변형되면서 흡수하게 됨으로써 센터필라아웃터패널의 변형을 최소화하여 자동차의 측면 충돌로부터 탑승자를 안전하게 보호하는 특유의 효과가 있다.As described above, according to the reinforcing structure of the center pillar portion of the vehicle according to the present invention, when the impact is applied to the center pillar portion, the impact force is absorbed while the two reinforcement members installed on the center pillar outer panel are deformed, thereby preventing the impact of the center pillar outer panel. There is a peculiar effect of minimizing deformation to protect the occupants from the side collision of the car.
