본 고안은 3도어식 승용차의 측면바디 보강구조에 관한 것으로, 더 상세히는 측면충돌시 승객을 보호할 수 있도록 임팩트바를 설치한 3도어식 승용차의 측면바디 보강구조에 관한 것이다.The present invention relates to a side body reinforcement structure of a three-door passenger car, and more particularly to a side body reinforcement structure of a three-door passenger car equipped with an impact bar to protect passengers in the event of a side collision.

일반적인 승용차에는 도어내에 임팩트바를 설치하여 측면충돌시 앞좌석 및 뒷좌석의 탑승자를 보호할 수 있도록 하였다.In general cars, impact bars are installed in the doors to protect occupants in the front and rear seats in the event of side impacts.

그런데, 제1도 및 제2도에 도시한 바와같이, 일반적인 3도어식 승용차의 측면바디 내측패널(10), 외측패널(2), 그리고 외측, 내측 휠하우스 패널(3)(4)이 점용접으로 연접되어 있는 구조이다. 이러한 구조로된 종래의 측면바디는 측면충돌시 충격량이 직접적으로 전달되어 특히 뒷좌석에 있는 승객에게 치명적인 상해를 준다.By the way, as shown in FIG. 1 and FIG. 2, the side body inner panel 10, the outer panel 2, and the outer and inner wheelhouse panels 3 and 4 of a typical three door passenger car have a point. It is a structure connected by welding. In the conventional side body having such a structure, the impact amount is directly transmitted in the case of a side collision, which causes particularly fatal injury to the passenger in the rear seat.

다시 말해서 앞좌석쪽에는 도어가 있으므로 도어내에 설치된 임팩트바에 의해서 충격량의 상당량을 흡수하여 앞좌석의 승객을 보호하여 줄 수 있으나, 도어가 없는 뒷좌석쪽에는 충격량을 흡수하는 구조가 미약하여 충격량이 직접적으로 전달되므로 뒷좌석에 있는 승객의 피해정도가 심해진다.In other words, since the front seat has a door, the impact bar installed in the door can absorb a considerable amount of impact and protect the passengers in the front seat.However, the back seat without the door has a weak structure that absorbs the shock. As it is transmitted, the damage of passengers in the rear seats is increased.

상술한 종래의 문제점을 감안한 본 고안은 뒷좌석에 대응하는 측면바디에 임팩트바를 설치하여 측면충돌시 충격을 흡수하므로써 뒷좌석 승객을 보호하는데 목적이 있다.The present invention in view of the above-described problems has an object to protect the rear passengers by installing an impact bar on the side body corresponding to the rear seat by absorbing the impact during side impact.

이러한 목적에 따른 본 고안의 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.One embodiment of the present invention for this purpose will be described in detail with reference to the accompanying drawings.

본 고안은 내측 패널(10), 외측 패널(20), 그리고 외측, 내측 휠하우스 패널(30)(40)이 연접되게 결합되어 있는 3도어식 승용차의 측면바디에 있어서, 상기 내측패널(10)과 상기 외측패널(20) 내측면에 연접되게 제1보강판(50)을 부착하고, 상기 외측 휠 하우스패널(30) 내측면에 제2보강판(60)을 부착하고, 상기 제1보강판(60)과 상기 제2보강판(60)에 양단이 고정되며 상기 외측패널(20) 내측면에 인접되게 임팩트바(70)를 설치하여서 된 것이다.The present invention is the inner panel 10, the outer panel 20, and the outer side, inner wheel house panel 30, 40, in the side body of the three-door passenger car coupled to the joint, the inner panel 10 And a first reinforcing plate 50 to be in contact with the inner side of the outer panel 20, and attaching a second reinforcing plate 60 to the inner side of the outer wheel house panel 30, and the first reinforcing plate. Both ends are fixed to the 60 and the second reinforcing plate 60 and the impact bar 70 is installed adjacent to the inner side of the outer panel 20.

본 고안에 있어서, 제1고강판(50)은 ㄱ자 형상의 단면을 갖으며, 제2보강판(60)은 곡선적인 단면을 갖도록 한다. 그리하여 제1보강판(50)은 내측패널(10) 및 외측패널(20)에 양측면을 점용접하고, 제2보강판(60)은 외측 휠하우스패널(30)에 밀착되게 점용접한다. 그리고 본 고안에 따른 임팩트바(70)는 중실(中失) 또는 중공(中空)의 환봉을 이용하여 측면바디의 내측면의 구조에 따라 굴곡형성하여 그 일단은 제1보강판(50)에 그 타단은 제2보강판(60)에 연결한다. 이때 임팩트바(70)를 제1보강판(50) 및 제2보강판(60)에 용접으로 연결하는 것이 바람직하다.In the present invention, the first steel sheet 50 has a cross-section of the L-shape, the second reinforcing plate 60 to have a curved cross section. Thus, the first reinforcing plate 50 is spot welded on both sides of the inner panel 10 and the outer panel 20, the second reinforcing plate 60 is spot welded in close contact with the outer wheel house panel (30). And the impact bar 70 according to the present invention is bent according to the structure of the inner surface of the side body using a solid or hollow round bar, one end of the first reinforcing plate 50 The other end is connected to the second reinforcing plate (60). At this time, it is preferable to connect the impact bar 70 to the first reinforcing plate 50 and the second reinforcing plate 60 by welding.

그리고 이 임팩트바(70)는 외측패널(20)과 일정하게 간격을 둠으로써 1차적인 충격은 외측패널에서 흡수하고 2차적인 충격을 임팩트바(70)에서 흡수하게 된다.In addition, the impact bar 70 is regularly spaced apart from the outer panel 20 so that the primary shock is absorbed by the outer panel and the secondary shock is absorbed by the impact bar 70.

이와같은 구조로된 본 고안은 뒷좌석에 해당하는 위치의 측면바디에 임팩트바(70)를 설치하였으므로 측면충돌시 외측패널(20)이 변형되어 실내측으로 침입되어 1차적으로 충격을 흡수하고, 나머지 충격량은 임팩트바(70)에서 충분히 흡수하게 된다. 그러므로 운행시 측면바디에 어느 정도까지 큰 충격을 받더라도 뒷좌석의 승객에 상해를 입지 않게 된다.The present invention having such a structure has an impact bar 70 installed on the side body at the position corresponding to the rear seat, so when the side collision occurs, the outer panel 20 is deformed and penetrates into the room, absorbing the impact primarily, and the remaining impact amount. Is sufficiently absorbed in the impact bar (70). Therefore, even if the vehicle is severely impacted to the side of the car to some extent, the passengers in the rear seats are not injured.

상술한 바와같이 본 고안은 측면바디에 임팩트바를 설치하여 강성을 증대시킨 구조로서, 측면충돌시 충격량을 흡수하여 승객의 안전을 확보하므로 차량의 안전성에 기여한 것이다.As described above, the present invention has a structure in which an impact bar is installed on the side body to increase rigidity, and thus absorbs an impact amount during side collision, thereby contributing to the safety of the vehicle.
