본 고안은 플로어패널 이면으로 제1,2,3 보강부로 이루어진 보강체를 용접 설치함으로써 그 강도를 보강함에 따라 플로어패널의 파손을 방지하여 인체의 안전을 최대한 보장할 수 있게 된 자동아의 플로어패널 보강구조에 관한 것이다.The present invention is to install the reinforcement body consisting of the first, second, third reinforcement on the back of the floor panel by reinforcing its strength to prevent the damage to the floor panel, which can ensure the safety of the human body to the maximum. It relates to a reinforcement structure.

일반적으로, 언더 바디(Under body)는 플로어패널이라고 하는 것으로 바디 밑면, 즉 바닥 부분이 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, the underbody is called a floor panel, and the underside of the body, that is, the bottom part, is an underbody, 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 상기 플로어패널(Floor panel)에는 측면 충돌시 그 충격을 최소화시키기 위한 구조로, 종래에는 플로어패널의 상면에는 부분적으로 보강 구조를 용접하여 설치했다. 또 플로어패널 상면이나 이면에 별도의 클로스 멤버를 구비하여 용접 설치토록 하였다.By the way, the floor panel (floor panel) is a structure for minimizing the impact when the side impact, conventionally installed in the upper surface of the floor panel by welding a reinforcing structure partially. In addition, separate cloth members were provided on the top and rear surfaces of the floor panel for welding installation.

즉, 자동차 운행 도중에 측면 충돌이 발생했을 경우, 그 충격이 상기 플로어패널을 파손시키게 되는 데, 상기와 같이 수개소로 형성된 보강구조에 의해 그 파손이 완화되는 것이다. 이렇게 플로어패널의 파손이 최소화됨에 따라 이에 탑승한 운전자 및 탑승자들에 가해지는 충격이 적어져 인체에 손상이 가해지는 것을 최대한 방지할 수 있게 되었다.That is, when a side collision occurs during driving of the vehicle, the impact causes the floor panel to be damaged, and the damage is alleviated by the reinforcement structure formed in several places as described above. 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.

그렇지만 상기와 같은 보강구조만으로 측면 충돌시 승객들의 안전을 완벽하게 보장할 수 없는 등의 문제가 발생되었다. 더욱이 상기 보강구조는 플로어패널과 일체형이 아니기 때문에 충돌 발생시 터널의 손상이 종종 발생하였다.However, the above-mentioned reinforcing structure alone has a problem such as not fully guarantee the safety of the passengers in the event of a side collision. Moreover, since the reinforcing structure is not integrated with the floor panel, the tunnel is often damaged in the event of a collision.

아울러 상기와 같이 클로스멤버를 덧대는 공정이 필요하기 때문에 복잡한 작업공수가 따랐고, 이와 같이 클로스 멤버가 설치됨에 따라 그 부문이 돌출되어 이에 탑승하는 승객의 탑승 공간이 줄어들어 불편함이 초래되기도 했었다.In addition, since the process of adding a cloth member is required as described above, a complicated workmanship is followed, and as the cloth member is installed in this way, the sector protrudes and the boarding space of the passengers boarding it is reduced, resulting in inconvenience.

따라서 본 고안은 목적은, 플로어패널에 보강체를 용접 설치하여 강도를 보강함에 따라 플로어패널의 파손을 방지할 수 있게 되므로 인체의 안전을 최대한 보장할 수 있게 되는 자동차의 플로어패널 보강구조를 제공하는데 있다.Therefore, an object of the present invention is to provide a floor panel reinforcement structure of a vehicle that can prevent the damage to the floor panel by welding the reinforcement to the floor panel and thereby reinforcing strength. have.

본 고안의 목적은, 플로어패널 이면에는 보강체를 횡방향으로 용접 설치하되 그 보강체 일단에는 상기 플로어패널의 터널 측면으로 끝단이 접촉되게 제2,3 보강부를 분기하여 형성하고, 타단에는 상기 플로어패널의 측단까지 설치되게 제1 보강부를 형성함으로써 달성되는 것이다.An object of the present invention is to install a reinforcement in the transverse direction on the back of the floor panel, but the reinforcement is formed by branching the second and third reinforcement parts so that the end contact with the tunnel side of the floor panel, and the other end of the floor It is achieved by forming the first reinforcement to be installed up to the side end of the panel.

이하, 본 고안 자동차의 플로어패널 보강구조에 따른 바람직한 일 실시예를 첨부된 도면에 의해 자세히 기술한다.Hereinafter, a preferred embodiment according to the floor panel reinforcement structure of the present invention car will be described in detail by the accompanying drawings.

첨부도면 제1도는 본 고안의 일 실시예를 보인 정단면도인데, 이에 도시된 바와같이 본 고안은 중앙부위에는 배기 시스템(E)이 통과되도록 터널(12)이 종방향으로 포밍 형성된 자동차의 플로어패널 보강구조에 있어서, 상기 플로어패널(10) 이면에는 보강체(20)를 횡방향으로 용접 설치하되 그 보강체(20) 일단에는 상기 플로어패널(10)의 터널(12) 측면으로 끝단이 접촉되게 제2,3 보강부(22)(23)를 분기하여 형성하고, 타단에는 상기 플로어패널(10)의 측단까지 설치되게 제1 보강부(21)를 형성하여 된 것이다.1 is a front sectional view showing an embodiment of the present invention, as shown in the present invention, the tunnel panel is formed in the longitudinal direction so that the exhaust system E passes through the central portion of the floor panel reinforcement of the vehicle. In the structure, the bottom of the floor panel 10 is welded to the reinforcement 20 in the transverse direction, but one end of the reinforcing body 20 to the end contact with the tunnel 12 side of the floor panel 10 The second and third reinforcement parts 22 and 23 are formed by branching, and at the other end, the first reinforcement part 21 is formed to be installed up to the side end of the floor panel 10.

이와 같이 구성된 본 고안의 작용 효과를 상세히 설명한다.The effect of the present invention configured as described above will be described in detail.

즉, 도면 제2도는 제1도에서 보강체만을 보인 사시도인데, 보강체(20)를 도면에서처럼 제1,2,3 보강부(21)(22)(23)로 분기하여 형성한 다음 상기 플로어패널(10)의 이면에 용접 설치하게 된다. 이때 상기 제1 보강부(21) 끝단은 상기 플로어패널(10)의 측면에 위치되게 하고 반대쪽의 제2,3 보강부(22)(23) 끝단은 상기 플로어패널(10)의 터널(12) 측면에 접촉되게 설치하게 되는 것이다.That is, FIG. 2 is a perspective view showing only the reinforcement in FIG. 1, and the reinforcement 20 is formed by branching into the first, second, and third reinforcement parts 21, 22, and 23 as shown in the drawing, and then the floor. The back surface of the panel 10 is welded. At this time, the end of the first reinforcement portion 21 is positioned on the side of the floor panel 10 and the end of the second and third reinforcement portions 22 and 23 on the opposite side is the tunnel 12 of the floor panel 10. It will be installed in contact with the side.

전술한 것과 같이 상기 플로어패널(10)에 보강체(20)가 설치된 상태에서 측면 충돌 실험을 하게 되면, 우선 그 충격력이 플로어패널(10)과 보강체(20)의 제1 보강부(21)가 동시에 받게 되므로, 그 충격력을 견딜 수 있는 강도가 향상되는 것이고, 아울러 보강체(20)의 제1 보강부(21)에 전달된 충격력은 제2,3 보강부(22)(23)에 나뉘어져 전달되기 때문에 충격력이 약화되는 것이다. 다시말해 상기와 같이 전달된 충격력은 그 힘이 분산되어 플로어패널(10) 및 터널(12)이 파손되는 것을 효과적으로 방지할 수 있게 되는 것이다.As described above, when the side impact experiment is performed in the state where the reinforcement body 20 is installed in the floor panel 10, first, the impact force is the first reinforcement part 21 of the floor panel 10 and the reinforcement body 20. Is simultaneously received, the strength that can withstand the impact force is improved, and the impact force transmitted to the first reinforcement portion 21 of the reinforcement body 20 is divided into the second and third reinforcement portions 22 and 23 The impact force is weakened because it is transmitted. In other words, the impact force transmitted as described above may effectively prevent the floor panel 10 and the tunnel 12 from being damaged by the dispersion of the force.

이상에서 상세히 설명한 바와 같이 본 고안 자동차의 플로어패널 보강구조에 따르면, 보강체에 의해 측면 충돌시 강도가 보강됨과 동시에 그 힘이 분산됨에 따라 플로어패널의 파손을 방지하게 되며 탑승자의 안전을 도모할 수 있게 된 고안이다.As described in detail above, according to the floor panel reinforcement structure of the present invention, the strength of the side collision is reinforced by the reinforcement body and the force is dispersed, thereby preventing the floor panel from being damaged and promoting the safety of the occupant. It is a devised design.
