본 고안은 자동차 도어의 내부에 장착되는 임팩트바의 보강판에 관한 것으로서, 특히 측면 충돌시 효과적으로 충격을 완충하여 승원의 안전성이 향상되도록 하는 자동차 도어의 임팩트바 보강구조에 관한 것이다.The present invention relates to a reinforcement plate of an impact bar mounted inside an automobile door, and more particularly, to an impact bar reinforcement structure of an automobile door that effectively buffers an impact during side impact and improves safety of the occupant.

일반적으로, 자동차 도어는 측면충돌시 충격에너지를 효과적으로 흡수하여 승원의 안전성을 확보하기 위해, 제1도에 도시되는 바와 같이 도어(10) 내부에 임팩트바(20)가 장착되고, 임팩트바(20) 측부에 임팩트바(20)를 보강해 주는 보강판이 도어 내측판에 부착되어 있다.In general, in order to secure the safety of the occupant by effectively absorbing the impact energy in the event of a side collision, as shown in FIG. 1, the impact bar 20 is mounted inside the door 10, the impact bar 20 A reinforcing plate for reinforcing the impact bar 20 on the side is attached to the door inner plate.

여기에서, 임팩트바의 보강구조는, 제2도에 도시되는 바와 같이, 내측판넬(door in panel)과 외측판넬(door out panel)이 소정의 간격을 두고 연결되는 도어(10) 내부에 폐공간이 형성되어, 상기 폐공간 내부에서 도어(10)의 외측판넬 하단부에 곡면을 형성되는 보강판(30)이 소정의 공간을 두고 취부되고, 보강판(30)과 외측판넬 사이에서 임팩트바(20)의 양단부가 도어(10)의 전면과 후면에 고정되었다.Here, the reinforcement structure of the impact bar is, as shown in Figure 2, the closed space inside the door 10, the door in panel and the door out panel is connected at a predetermined interval Is formed, the reinforcing plate 30 is formed in the closed space to form a curved surface at the lower end of the outer panel of the door 10 with a predetermined space, the impact bar 20 between the reinforcing plate 30 and the outer panel Both ends of the) are fixed to the front and rear of the door (10).

이러한 종래 자동차 도어의 임팩트바 보강구조는, 측면충돌시 측부에서 실내쪽으로 작용하는 충격에너지 도어(10)의 외측판넬과 임팩트바(20)에 의해 흡수되도록 하며, 임팩트바(20)가 보강판(30)에 지지되어 충격을 견디는 강성이 향상되도록 하는데, 보강판(30)과 임팩트바(20)가 단순히 면접촉되어, 임팩트바(20)를 보강하는 기능이 효과적이지 못한 단점이 있었다.The impact bar reinforcement structure of the conventional car door is to be absorbed by the impact panel 20 and the outer panel of the impact energy door 10 acting from the side to the interior when the side impact, the impact bar 20 is a reinforcement plate ( It is supported by 30 to improve the rigidity to withstand the impact, the reinforcing plate 30 and the impact bar 20 is simply a surface contact, there was a disadvantage that the function to reinforce the impact bar 20 is not effective.

본 고안의 목적은 상기와 같은 종래의 단점을 해소하기 위해, 다단으로 절곡되어 수납홈이 형성되는 보강판을 도어 내부에서 횡방향으로 장착하고, 상기 보강판의 수납홈에 임팩트바가 장착되도록 하여, 상기 임팩트바가 보강판과 일체로 충격에너지를 흡수하도록 하고, 상기 보강판에 압축응력이 작용되도록 하는 자동차 도어의 임팩트바 보강구조를 제공하는 데 있다.An object of the present invention is to relieve the above-mentioned drawbacks, to mount the reinforcement plate is bent in multiple stages to form a receiving groove in the transverse direction inside the door, so that the impact bar is mounted to the receiving groove of the reinforcing plate The impact bar is to provide an impact bar reinforcement structure of the automobile door to absorb the impact energy integrally with the reinforcement plate, the compression stress is applied to the reinforcement plate.

이하 첨부된 도면에 의하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

본 고안은 제3도에 도시되는 바와 같이, 내측판넬과 외측판넬이 소정의 간격을 두고 연결되는 도어(10) 내부에서 다단으로 절곡되어 수납홈이 형성되는 보강판(30)의 일단부가 외측판넬에 부착되고, 보강판(30)의 타단부가 도어(10)의 내측판넬에 취부되며, 보강판(30)의 수납홈에 임팩트바(20)의 외부면이 수납되게 장착됨을 그 기술적 구성상의 기본 특징으로 한다.The present invention, as shown in Figure 3, one end of the reinforcing plate 30 is bent in multiple stages in the interior of the door 10 is connected to the inner panel and the outer panel at a predetermined interval to form a receiving groove outer panel The other end of the reinforcement plate 30 is attached to the inner panel of the door 10, and the outer surface of the impact bar 20 is mounted in the receiving groove of the reinforcement plate 30 so as to be stored therein. It is a basic feature.

여기에서, 보강판(30)은 도어(10)의 외측판넬에 부착되는 일단부가 외측판넬과 소정의 공간을 두고 하부로 연장되고, 외측판넬 하단부에서 다시 절곡되어 수납홈을 형성하며 연장되어 도어(10)의 내측판넬에 연결되도록 함이 바람직하다.Here, the reinforcement plate 30 has one end portion attached to the outer panel of the door 10 extending downward with the outer panel and a predetermined space, and is bent again at the lower end of the outer panel to form an accommodating groove to extend the door ( It is preferable to be connected to the inner panel of 10).

한편, 도어(10)가 밀착되는 차체(40)는 내부에 보조보강판(41)을 취부하여, 충돌시 보강판(30)이 도어(10)의 내측판넬 및 차체(40)를 파손하고 내부로 진입하는 것을 억제하도록 함이 바람직하다.On the other hand, the vehicle body 40 in which the door 10 is in close contact with the auxiliary reinforcement plate 41 is installed inside, so that the reinforcement plate 30 damages the inner panel and the vehicle body 40 of the door 10 during a collision. It is desirable to suppress the entry into.

이와같이 구성되는 본 고안은, 보강판(30)이 도어(10)의 횡방향으로 장착되고, 보강판(30)의 수납홈 내부에 임팩트바(20)가 수납되는 구조로 되어, 측방향에서 충격하중이 작용하면, 임팩트바(20)가 보강판(30)과 일체로 충격에너지를 흡수하게 되고, 보강판(30)의 하단부에 벤딩이 아닌 압축응력이 작용하게 되어 비교적 큰 하중을 견딜 수 있도록 한다.The present invention constituted as described above has a structure in which the reinforcement plate 30 is mounted in the transverse direction of the door 10, and the impact bar 20 is accommodated in the receiving groove of the reinforcement plate 30. When the load is applied, the impact bar 20 absorbs the impact energy integrally with the reinforcing plate 30, and the compressive stress is applied to the lower end of the reinforcing plate 30, rather than bending, to withstand a relatively large load. do.

따라서, 이러한 본 고안은, 측면충돌시 실내쪽으로 작용하는 충격을 다중으로 완충하고 진입을 억제하여, 승원의 안전성을 향상시켜 주는 효과가 있다.Therefore, the present invention has an effect of improving the safety of the occupant by cushioning the impact acting toward the room in the event of a side collision in multiple and inhibiting entry.

여기서, 미설명부호 11은 유리이다.Here, reference numeral 11 is glass.

이상에서 살펴본 바와 같이, 본 고안은 다단으로 절곡되어 수납홈이 형성되는 보강판이 도어 내부에서 횡방향으로 장착되고, 상기 보강판의 수납홈에 임팩트바가 장착되어, 효과적으로 충격을 완충시켜 주는 매우 유용한 것이다.As described above, the present invention is a reinforcement plate that is bent in multiple stages to form a receiving groove is mounted in the transverse direction inside the door, the impact bar is mounted to the receiving groove of the reinforcing plate is very useful to effectively cushion the impact .
