본 고안은 자돛아의 도어 앰픽트 멤버 보강구조에 관한 것으로, 더 상세하게는 도어의 내부상단에 설치되는 임팩트멤버에 완충부재를 설치하여 임팩트멤버의 강성을 증대하므로써 차량 측면 충돌시 도어에 가해지는 충격량을 완충부재와 임팩트멤버에서 다단계에 걸쳐 흡수하여 도어의 변형 감소 및 탑승자의 안전을 최대한 보호할 수 있도록 한 것이다.The present invention relates to a reinforcing structure of a door member member of Jasaia, and more particularly, by installing a shock absorbing member on an impact member installed at an inner upper part of the door, thereby increasing the rigidity of the impact member. The impact amount is absorbed in multiple stages from the cushioning member and the impact member to reduce the deformation of the door and protect the occupant's safety as much as possible.

일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌과 측면충돌 등 여러가지 테스트가 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 큰 항목으로 이용하고 있다.In general, there are various tests such as a front collision and a side collision in order to ensure the safety of passengers in the event of a car crash. This is an important factor to secure the safety of the car. It is used as a large item such as import regulation.

그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다. 즉, 그 원인으로는 차체의 도어 보강구조가 취약하기 때문이다.However, most of the automobiles currently produced have some safety values for forward collisions, but the safety values for side collisions are insufficient. That is, the reason is that the door reinforcement structure of the vehicle body is weak.

한편, 종래의 도어(1) 보강구조는 제 2 도에서와 같이 도어인너패털(2)의 외측으로 도어아웃터패널(2) 외측으로 도어아웃터패널(3)이 설치되며, 상기 도어아웃터패널(3)의 내측면으로는 강성보강을 위해 하부에는 임팩트바(4)가 설치되며,상부에는 외측 상,하단부에 플랜지(5)가 형성되며, 전, 후방 단부로는 고정부가 구비된 임팩트멤버(6)가 설치된다.Meanwhile, in the conventional door 1 reinforcing structure, as shown in FIG. 2, the door outer panel 3 is installed outside the door inner panel 2, and the door outer panel 3 is provided. The inner side of the) for the rigid reinforcement is installed on the bottom of the impact bar (4), the upper portion of the upper and lower ends, the flange 5 is formed, the front and rear end of the impact member (6) ) Is installed.

그러나, 상기와 같은 종래의 임팩트멤버(6)는 단순히 패널이 절곡성형된 것이어서, 임팩트멤버(6) 자체의 강성이 미약하여 차량 측면충돌시 도어아웃터패널(3)이 찌그러지며 내측으로 밀려들어 오는 것을 차단하지 못하여 도어인너패널(2)에 그대로 충격이 전달되어 도어인너패널(2)이 찌그러지며 차량 실내로 밀려 들어오게 되어 도어(1)의 변형이 심하였으며, 그로 인하여 차내 탑승자에게 가해지는 충격량이 커지게 되는 문제점이 소지되어 있었다.However, the conventional impact member 6 is simply a panel formed by bending, so the rigidity of the impact member 6 itself is weak and the door outer panel 3 is crushed and pushed into the inner side when the vehicle collides. Since the shock was transmitted to the door inner panel 2 as it was not blocked, the door inner panel 2 was crushed and pushed into the vehicle interior, so that the deformation of the door 1 was severe, and thus the amount of impact applied to the occupant in the vehicle. This problem of getting bigger was possessed.

본 고안은 이러한 제반 문제점을 해소하기 위해 안출된 것으로, 도어의 내부상단에 설치되는 임팩트멤버에 완충부재를 내설하여 임팩트 멤버의 강성을 증대시켜 차량 측면충돌시 완충부재와 임팩트멤버에서 충격량을 충분히 흡수하여 도어의 변형을 감소시키며, 차내 탑승자의 안전성을 향상시키려는데 그 목적이 있다.The present invention was devised to solve the above problems. The shock absorbing member is installed in the impact member installed in the upper part of the door to increase the rigidity of the impact member, thereby sufficiently absorbing the impact amount from the shock absorbing member and the impact member when the vehicle side impacts. The purpose is to reduce the deformation of the door, and to improve the safety of the occupant in the car.

상기의 목적을 달성하기 위한 본 고안은, 내부에 버팀판이 결합된 완충부재를 임팩트멤버의 내부에 설치하는 구조로, 상기 완충부재와 버팀판 및 임팩트멤버에서 차량 측면충돌시 발생되는 충격량이 다단계에 걸쳐 흡수된다.The present invention for achieving the above object is a structure that installs the shock absorbing member coupled to the support plate in the interior of the impact member, the impact amount generated when the vehicle side collision in the shock absorbing member and the support plate and the impact member in multiple stages Absorbed across.

이하 첨부된 도면에 의거하여 본 고안의 구성을 설명하면 다음과 같다.Referring to the configuration of the present invention based on the accompanying drawings as follows.

제 3도 내지 제 4도에서 도시되는 바와 같이 본 고안은 전, 후방 단부에는 고정부(21)가 형성되며, 외측 상, 하단부로 플랜지(22)가 구비된 임팩트 멤버(20)의 내부로는 외측단부에 지지부(42)가 형성되며, 강성증대를 위해 절곡 성형된 버팀판(30)이 내설된 완충부재(40)가 일정간격으로 다수개가 설치되어, 상기 완충부재(40)의 지지부(42)는 임팩트트멤버(20)의 플랜지(22)와 도어아웃터패널(10)의 사이에 밀착되며, 임팩트멤버(20)의 고정부(21)는 도어인너패널의 외측면 상부에 용접에 의해 결합하되, 상기 임팩트멤버(20)의 내측면에는 후크공(23)이 천공되며, 완충부재(40)의 내측으로는 상기 후크공(23)에 결합되는 이탈방지용 후크(41)가 돌출된다.As shown in FIG. 3 to FIG. 4, the present invention has a fixing portion 21 formed at the front and rear ends thereof, and the inside of the impact member 20 having the flange 22 at the upper and lower ends thereof. A support part 42 is formed at the outer end, and a plurality of buffer members 40 in which the support plate 30 is formed to be bent to increase rigidity are installed at regular intervals, thereby supporting the support part 42 of the buffer member 40. ) Is in close contact between the flange 22 of the impact member 20 and the door outer panel 10, the fixing portion 21 of the impact member 20 is coupled to the upper portion of the outer surface of the door inner panel by welding. However, the hook hole 23 is drilled on the inner surface of the impact member 20, and the separation prevention hook 41 coupled to the hook hole 23 protrudes inside the buffer member 40.

상기 완충부재(40)는 자체탄성력을 갖는 고무, 스폰지 등이 사용된다.The buffer member 40 is used, such as rubber, sponge having a self-elasticity.

이와같은 구조로 인하여 본 고안은 임팩트멤버(20)에 형성된 후브공(23)에 버팀판(30)이 내설된 완충부재(40)의 후브(41)를 일치시킨 상태에서 완충부재(40)를 밀게되면 후크공(23)의 내경보다 외경이 큰 후크(41)가 자체탄력에 의해 수축되면서 후크공(23)에 로킹되고, 후크(41)가 완전히 체결되면 자체탄력에 의해 복원되어 후크공(23)으로부터 이탈되는 것이 방지되며, 차량 측면충돌시 도어아웃패널(10)에 가해진 충격에 의해 도어아웃터패널(10)이 찌그러지며 실내측으로 전달하는 충격량을 완충부재(40)가 1차로 흡수하며, 상기 완충부재(40)의 내부에 결합된 버팀판(30)이 찌그러지며 2차로 충격량을 흡수하며, 상기 완충부재(40)와 버팀판(30)에서 흡수하지 못한 충격량을 3차로 절곡성형된 임팩트멤버(20)에서 흡수한다.Due to such a structure, the present invention uses the cushion member 40 in a state in which the hub 41 of the buffer member 40 in which the support plate 30 is installed is aligned with the hub hole 23 formed in the impact member 20. When pushed, the hook 41 having an outer diameter larger than the inner diameter of the hook hole 23 is locked to the hook hole 23 while being contracted by its own elasticity, and when the hook 41 is completely fastened, the hook 41 is restored by its own elasticity so that the hook hole ( 23) is prevented from being separated, the shock absorbing member 40 is primarily absorbed by the shock applied to the door out panel 10 by the impact applied to the door out panel 10 when the vehicle side impact, the interior side, The impact plate 30 coupled to the interior of the shock absorbing member 40 is crushed and absorbs the impact amount secondly, and the impact amount that is not absorbed by the shock absorbing member 40 and the support plate 30 is bent in the third order. Absorb in the member 20.

따라서, 이러한 본 고안은 외부로부터의 충격이 다단계에 걸쳐 흡수, 완화됨은 물론 변형이 방지되므로 탑승자의 안전을 확보하는 동시에 차량의 측면충돌에 대한 안전치 법규만족에 충분히 대응할 수 있다.Therefore, the present invention can be absorbed and mitigated in multiple stages, as well as the deformation is prevented from the outside to ensure the safety of the occupants and at the same time can fully satisfy the safety regulations for side collision of the vehicle.

이상에서 살펴본 바와같이 차량 측면충돌시 버팀판이 내설된 완충부재와 임팩트멤버에서 다단계에 걸쳐 충격량을 충분히 흡수하게 되므로 도어의 강성이 보강되어 차량 실내로 전달되는 충격량이 감소되어 탑승자의 안전성을 향상시킬 수 있는 매우 유용한 고안이다.As described above, when the side impact of the vehicle, the support plate absorbs the shock amount sufficiently in the shock absorbing member and the impact member in the multi-stage, so the rigidity of the door is reinforced to reduce the amount of impact transmitted to the interior of the vehicle, thereby improving passenger safety. That is a very useful design.
