일반적으로, 차체의 바닥을 이루는 플로어패널(1)은 도 1에 도시된 바와 같이, 차체의 전방쪽 바닥면을 구성하는 프런트플로어패널(10)과, 후방쪽 바닥면을 구성하는 리어플로어패널(20) 및, 이 리어플로어패널(20)과 프런트플로어패널(10)을 연결하는 센터플로어패널(30)로 이루어져 있다.In general, the floor panel 1 forming the bottom of the vehicle body, as shown in Figure 1, the front floor panel 10 constituting the front bottom surface of the vehicle body, and the rear floor panel constituting the rear bottom surface ( 20) and a center floor panel 30 for connecting the rear floor panel 20 and the front floor panel 10 to each other.

여기서, 상기 센터플로어패널(30)은 도 4 내지 도 6에 도시된 바와 같이, 상기 프런트플로어패널(10)과 용접에 의해 결합되는 상부센터플로어패널(31) 및, 상기 리어플로어패널(20)과 용접에 의해 결합되는 하부센터플로어패널(32)로 이루어져 있으며, 상기 상하부센터플로어패널(31,32)도 서로 용접에 의해 단단히 결합되어 있다.Here, the center floor panel 30 is an upper center floor panel 31 coupled to the front floor panel 10 by welding, as shown in Figures 4 to 6, and the rear floor panel 20 And a lower center floor panel 32 coupled by welding, and the upper and lower center floor panels 31 and 32 are also firmly coupled to each other by welding.

여기서, 상기 하부센터플로어패널(32)의 양단부위에 구비된 안착부(32a)에는 내외부를 관통하는 소정크기의 조립구멍(32b)이 각각 형성되어 있는 바, 상기 안착부(32a)에는 조립구멍(32b)과 연결되도록 관통구멍(41)이 각각 형성된 한쌍의 마운팅브라켓트(40)가 볼트(51)와 너트(52)의 결합에 의해 단단히 고정되도록 설치되어 있다.Here, assembling holes 32b of a predetermined size penetrating inside and outside are formed in the seating portions 32a provided at both ends of the lower center floor panel 32, and the assembling holes are formed in the seating portions 32a. A pair of mounting brackets 40 each having a through hole 41 formed to be connected to 32b) is installed to be firmly fixed by the coupling of the bolt 51 and the nut 52.

그리고, 상기 안착부(32a)에는 도 5와 도 6에 도시된 바와 같이, 상기 플로어패널(1)의 전체적인 굽힘강성 및 비틀림강성을 보강하여 섀시프레임과 바디패널을 통해 노면으로부터 전달되는 충격력을 효과적으로 분산시키기 위한 보강브라켓트(60)가 설치되되, 상기 보강브라켓트(60)는 마운팅브라켓트(40)의 양측면과 후방부를 감싸는 형태로 그 아랫면이 안착부(32a)에 단단히 고착되어 있다.5 and 6, the seating portion 32a reinforces the overall bending stiffness and torsional stiffness of the floor panel 1 to effectively prevent the impact force transmitted from the road surface through the chassis frame and the body panel. A reinforcing bracket 60 is installed to disperse, but the reinforcing bracket 60 is firmly fixed to the seating portion 32a in such a manner as to surround both sides and the rear portion of the mounting bracket 40.

따라서, 본 발명에 따른 보강브라켓트(60)가 마운팅브라켓트(40)를 감싸는 형태로 하부센터플로어패널(32)의 양단부위에 구비된 안착부(32a)로 설치되면, 상기 마운팅브라켓트(40)와 더불어 바디프레임(도시않됨)을 통해 전달되는 하중을 충분히 지탱해줄 뿐만 아니라, 상기 플로어패널(1)의 전체적인 굽힘강성과 비틀림강성이 향상되게 된다.Therefore, when the reinforcing bracket 60 according to the present invention is installed as a seating portion 32a provided at both ends of the lower center floor panel 32 in a form surrounding the mounting bracket 40, the mounting bracket 40 is provided together with the mounting bracket 40.

그리고, 본 발명에 따른 보강브라켓트(60)에 의해 플로어패널(1)의 전체적인 굽힘강성과 비틀림강성이 향상되면, 섀시프레임 및 바디패널을 통해 노면으로부터 전달되는 충격력이 보강브라켓트(60)에 의해 효과적으로 분산되므로, 노면상태가 좋지 않은 도로를 장시간 주행할 경우에도 바디패널과 결합되는 부위에 집중하중이 발생되지 않게되며, 이로인해 바디패널과 결합되는 센터플로어패널(30)의 결합부위에 균열이 생기는 것이 방지되므로, 차체의 안정성이 도2에 도시된 종래의 구조보다 증진되게 된다.Then, when the overall bending stiffness and torsional rigidity of the floor panel 1 are improved by the reinforcing bracket 60 according to the present invention, the impact force transmitted from the road surface through the chassis frame and the body panel is effectively by the reinforcing bracket 60. Since it is dispersed, even when driving on a road with poor road conditions for a long time, the concentrated load is not generated at the portion where the body panel is coupled, and thus cracks are generated at the coupling portion of the center floor panel 30 coupled with the body panel. Since it is prevented, the stability of the vehicle body is improved over the conventional structure shown in FIG.

이상 설명한 바와 같이 본 발명에 의하면, 하부센터플로어패널의 안착부에 설치된 보강브라켓트가 마운팅브라켓트와 더불어 바디프레임을 통해 전달되는 하중을 충분히 지탱해줌은 물론, 플로어패널의 전체적인 굽힘강성과 비틀림강성이 향상되어, 섀시프레임 및 바디패널을 통해 노면으로부터 전달되는 충격력이 보강브라켓트에 의해 효과적으로 분산되므로, 노면상태가 좋지 않은 도로를 장시간 주행할 경우에도 바디패널과 결합되는 부위에 집중하중이 발생되지 않을 뿐만 아니라, 이로인해 바디패널과 결합되는 센터플로어패널의 결합부위에 균열이 생기는 것이 방지되므로, 차체의 안정성이 증진되는 효과가 있다.As described above, according to the present invention, the reinforcing bracket installed on the seating portion of the lower center floor panel sufficiently supports the load transmitted through the body frame together with the mounting bracket, as well as improving the overall bending and torsional rigidity of the floor panel. Since the impact force transmitted from the road surface through the chassis frame and the body panel is effectively distributed by the reinforcement bracket, the concentrated load is not generated in the area where the body panel is coupled even when the road surface is bad for a long time. This prevents cracks from occurring in the coupling portion of the center floor panel coupled to the body panel, thereby improving stability of the vehicle body.
