본 고안은 크로스 멤버 내부의 플로어패널에 보강체를 설치함으로써 측면 충돌시 발생되는 충격을 크로스 멤버와 함께 보강체가 흡수할 수 있게 되므로 플로어패널의 파손을 방지하게 되어 탑승자에게 안정성을 확보할 수 있는 자동차의 플로어패널 변형방지용 보강체에 관한 것이다.The present invention installs a reinforcement on the floor panel inside the cross member, so that the impact generated during side impact can be absorbed by the reinforcement along with the cross member, thereby preventing damage to the floor panel, thereby ensuring stability for the occupant. It relates to a floor panel deformation preventing reinforcement of the.
일반적으로, 언더 바디(Under body; 이하 플로어패널이라고 칭함)는 바디 밑면 즉 바닥부분이 언더 바디이고, 리어 서스펜션이나 종감속 기어 등의 구동장치가 부착되어 있으며 바디 강성(剛性)이라는 점에서 중요한 역할을 하고 있다. 서스펜션의 움직임이나 진동의 대책으로서, 멤버나 보강재가 있다. 또 바디의 측면, 즉 도어의 주면을 사이드 바디라고 하며, 전복되었을 때 변형을 최소한으로 억제한다는 것, 그것에 내구성 등이 고려되어 있다.In general, an under body (hereinafter referred to as a floor panel) is an underbody, that is, an underbody at the bottom of the body, and has an important role in that it is attached to a driving device such as a rear suspension or a deceleration gear and has body rigidity. Doing As countermeasures for movement and vibration of the suspension, there are members and reinforcements. In addition, the side of the body, that is, the main surface of the door is called a side body, and it is considered that the deformation is minimized when overturned, and durability thereof is considered.
그런데 크로스 멤버(Cross member)와 사이드 멤버(Side member)는 상기 플로어패널에 쓰여지고 있는 골격으로, 강도나 강성을 높이기 위하여 쓰여지고 있다. 전후나, 좌우방향의 비틀림이나 휘어짐을 방지하기 위하여 쓰이고 있으며 자동차 진행방향에 대하여 직각으로 설치되어 있는 것을 크로스 멤버, 전후방향으로 설치되어 있는 것을 사이드 멤버라고 불리운다.However, the cross member and side member are skeletons used in the floor panel and are used to increase strength and rigidity. It is used to prevent torsion or warping in the front and rear and right and left directions, and the one provided at right angles to the direction of travel of the vehicle is called the cross member, and the one installed in the front and rear directions is called side member.
즉, 자동차 운행 도중에 측면 충돌이 발생했을 경우, 그 충격이 상기 플로어패널을 측면 방향으로 파손시키게 되는데, 상기와 같이 설치된 크로스 멤버에 의해 그 파손이 최대로 완화되는 것이다. 이는 상기 크로스 멤버가 횡방향으로 설치되었기 때문이다.That is, when a side collision occurs while driving a vehicle, the impact causes the floor panel to be damaged in the lateral direction, and the damage is minimized by the cross member installed as described above. This is because the cross member is installed in the transverse direction.
이렇게 플로어패널의 파손이 최소화됨에 따라 이에 탑승한 운전자 및 탑승자들에 가해지는 충격이 적어져 인체에 손상이 가해지는 것을 최대한 방지할 수 있게 되었다. 그렇지만, 상기와 같은 크로스 멤버만으로 측면 충돌시 가해지는 충격으로부터 상기 플로어패널의 파손을 방지하는 데에는 한계가 있기 때문에 승객들의 안전한 탑승을 보장할 수 없는 등의 문제가 발생되었다.As the damage of the floor panel is minimized, the impact on the driver and the occupants of the floor panel is reduced, thereby preventing the damage to the human body as much as possible. However, since there is a limit in preventing the damage of the floor panel from the impact applied during the side collision with only the cross member as described above, there is a problem such as not being able to guarantee the safe boarding of the passengers.
따라서 본 고안의 목적은, 측면 충돌시 발생되는 플로어패널의 변형을 방지함으로써 탑승자의 안전성을 향상시킬 수 있는 자동차의 플로어패널 변형방지용 보강체를 제공하는데 있다.Accordingly, an object of the present invention is to provide a reinforcement for preventing deformation of a floor panel of a vehicle, which can improve safety of a passenger by preventing deformation of a floor panel generated during a side collision.
본 고안의 목적은 크로스 멤버 내부공간의 플로어패널 상면에는 보강체를 용접 설치하되 그 보강체의 상부 선단과 양측 하단에는 용접용 플렌지를 절곡 형성함으로써 달성되는 것이다.An object of the present invention is achieved by welding a reinforcement on the upper surface of the floor panel of the cross member internal space, but forming a welding flange at the upper end and both lower ends of the reinforcement.
이하, 본 고안 자동차의 플로어패널 변형방지용 보강체에 따른 바람직한 일 실시예를 첨부된 도면에 의해 자세하게 기술한다.Hereinafter, a preferred embodiment according to the floor panel deformation prevention reinforcement of the present invention car will be described in detail by the accompanying drawings.
첨부도면 제1도는 본 고안의 일 실시예를 보인 요부 정단면도이고, 제2도는 제1도에서 A-A' 선에 따른 측단면도인데, 이에 도시된 바와 같이 본 고안은 진행방향에 대하여 직각으로 설치된 크로스 멤버와 전후방향으로 설치된 사이드 멤버를 골격으로 하는 자동차의 플로어패널에 있어서, 상기 크로스 멤버(10) 내부공간의 플로어패널(20) 상면에는 보강체(30)를 용접 설치하되 그 보강체(30)의 상부 선단과 양측 하단에는 용접용 플렌지(32)(34)를 절곡 형성하여 된 것이다.1 is a front sectional view showing a main portion of an embodiment of the present invention, and FIG. 2 is a side sectional view taken along line AA ′ in FIG. 1, and as shown in the drawing, the present invention has a cross installed at a right angle with respect to a traveling direction. In a floor panel of a vehicle having a member and a side member installed in the front-rear direction, a reinforcement body 30 is welded to the upper surface of the floor panel 20 in the interior space of the cross member 10, but the reinforcement body 30 is welded thereto. The upper ends and the lower ends of both sides were formed by bending the welding flanges 32 and 34.
이와 같이 구성된 본 고안의 작용 효과를 상세히 설명한다.The effect of the present invention configured as described above will be described in detail.
우선, 상기 플로어패널(20)의 골격을 구성하기 위해 상기 크로스 멤버(10)와 사이드 멤버를 서로 사다리형으로 조합하여 뼈대를 구성하게 되는 것이다. 이는 상기 플로어패널(20)의 상면으로 설치되는 것이다. 상기 크로스 멤버(10)는 측면으로 휘거나 측면충돌시 파손되는 것을 방지하기 위한 것이다. 그렇지만 그 크로스 멤버(10) 만으로 측면충돌 발생시 플로어패널(20)이 파손되는 것을 효과적으로 방지할 수 없게 되어, 본 고안에서는 별도의 보강체(30)를 플로어패널(20)에 설치하는 것이다.First, in order to form a skeleton of the floor panel 20, the cross member 10 and the side member are combined with each other in a ladder to form a skeleton. This is installed on the upper surface of the floor panel 20. The cross member 10 is intended to prevent breakage when the side or the side impact. However, the cross member 10 alone cannot effectively prevent the floor panel 20 from being damaged in the event of a side collision, and according to the present invention, a separate reinforcement 30 is installed in the floor panel 20.
이에 상기 보강체(30)를 상기와 같이 설치된 크로스 멤버(10) 내부의 플로어패널(20)에 설치하게 되는 것이다. 이때 그 보강체(30)의 일측에 형성된 플렌지(32)는 사이드쪽 플로어패널(20)에 대면서 다른 부위에 형성된 플렌지(34)는 플로어패널(20)의 바닥에 댄 다음 그 플렌지(32)(34) 부분을 용접하여 설치하게 되는 것이다.Accordingly, the reinforcement 30 is installed on the floor panel 20 inside the cross member 10 installed as described above. At this time, the flange 32 formed on one side of the reinforcement 30 is on the side floor panel 20 while the flange 34 formed on the other part is placed on the bottom of the floor panel 20 and then the flange 32 ( 34) We will install the part by welding.
이렇게 함으로써, 만일 측면 충돌이 발생했을 때 종전에는 상기 크로스 멤버(10) 만으로 충격력을 견디게 한 것을, 본 고안에서는 그 크로스 멤버(10)와 보강체(30)가 함께 견딜 수 있게 되어 플로어패널(20)의 파손을 최대한 막아주는 것이다.By doing so, in the present invention, the cross member 10 and the reinforcement 30 can withstand the impact force with the cross member 10 only when the side collision occurs, and thus the floor panel 20 ) Is to prevent damage as much as possible.
이상에서 상세히 설명한 바와 같이 본 고안 자동차의 플로어패널 변형방지용 보강체에 따르면, 측면 충돌발생시 그 충격력에 의해 플로어패널이 파손되는 것을 보강체와 크로스 멤버가 동시에 막아주게 되어 탑승자의 안전성을 보다 향상시킬 수 있게 되는 고안이다.As described in detail above, according to the floor panel deformation preventing reinforcement body of the present invention, the reinforcement body and the cross member prevent the floor panel from being damaged by the impact force when the side collision occurs, thereby improving the safety of the occupant. It is devised to be.
