본 발명은 자동차 측면 충돌에 대한 도어의 강도를 확보하기 위해 도어 내부에 설치되는 충격흡수 부재에 관한 것으로, 특히 도어의 이너 패널에 가로방향으로 장착되는 임팩트 빔과 도어 외측 패널 사이에 긴밀하게 결합되어 측면 충돌에 대한 충격흡수 능력을 증대시켜 자동차 실내의 탑승자를 보다 안전하게 보호할 수 있도록 한 자동차 도어용 충격흡수 부재에 관한 것이다.The present invention relates to a shock absorbing member installed inside the door to secure the strength of the door against the vehicle side collision, in particular closely coupled between the impact beam mounted in the transverse direction to the inner panel of the door and the door outer panel The present invention relates to a shock absorbing member for an automobile door that increases the shock absorbing ability against a side collision to more safely protect a passenger in a vehicle interior.

일반적으로 임팩트 빔(Impact beam)은 자동차의 측면 충돌에 대한 도어의 강도를 확보하기 위하여 도어 내부에 가로방향으로 장착되는 보강재를 말하는데, 사이드 빔(Side beam)이라고도 불린다.In general, the impact beam refers to a reinforcement mounted horizontally inside the door in order to secure the strength of the door against the side impact of the vehicle, also called a side beam.

상기 도어의 강도(Strength)는 자동차의 측면 충돌 사고로 사이드 도어가 자동차 실내 방향으로 침입하는 것을 방지하기 위하여 도어에 요구되는 강도를 말한다.The strength of the door refers to the strength required for the door to prevent the side door from entering the vehicle interior due to a side collision of the vehicle.

종래에는 상기와 같이 자동차의 측면 충돌 사고시 탑승자를 보다 안전하게 보호할 수 있도록 한 임팩트 빔 또는 임팩트 바가 여러 가지 개발되어 실차에 적용하여 상용되고 있는데, 이러한 임팩트 빔은 단순히 양단부가 도어 이너 패널에 용접되어 고정되는 임팩트 빔 브래킷에 고정되는 구조로서, 자동차의 측면 충돌 사고시 도어 아우트 패널이 자동차 실내로 진입하는 것을 최소화하는 장점은 있으나, 자동차의 측면 충돌에 따른 효과적인 충격흡수 완화 및 충격을 저감시키는 기능은 구비하지 못하여 자동차에 탑승한 승객을 보다 안전하게 보호할 수 없는 등의 문제점이 있었다.Conventionally, a variety of impact beams or impact bars have been developed and commonly applied to actual vehicles to protect passengers more safely in the event of a side collision of a vehicle as described above. These impact beams are simply welded at both ends to a door inner panel to be fixed. It is a structure fixed to the impact beam bracket, which has the advantage of minimizing the entry of the door outer panel into the vehicle interior in the event of a side collision of the vehicle, but does not have the function to effectively reduce the shock absorption and reduce the impact caused by the side collision of the vehicle. There was a problem such as unable to protect the passengers in the car more securely.

The parts 16 and 161 are formed, and the hollow parts 16 and 161 consist of the hollow part 16 which has a honeycomb shape as shown in FIG. 3, and the hollow part 161 which has a triangular shape and continues vertically. do.

또한 상기 에너지 압소버(10)는 충격흡수 능력이 우수한 우레탄 러버(Rubber)를 주재료로 하여 길이방향으로 연속되게 성형되어 필요한 길이만큼 절단하여 사용할 수 있다.In addition, the energy absorber 10 may be used by cutting the required length by continuously forming in the longitudinal direction using a urethane rubber (Rubber) excellent in shock absorption ability as a main material.

다시 설명하면 도어 이너 패널(34)로 임팩트 빔 브래킷(22)이 고정 결합되고, 이 임팩트 빔 브래킷(22)으로 임팩트 빔(20)의 양단부가 용접 결합되며, 이 임팩트 빔(20)의 선단과 도어 아우트 패널(32) 사이로 상기 에너지 압소버(10)가 끼워져 결합된다.In other words, the impact beam bracket 22 is fixedly coupled to the door inner panel 34, and both ends of the impact beam 20 are welded to the impact beam bracket 22, and the tip of the impact beam 20 is welded. The energy absorber 10 is inserted into and coupled between the door outer panel 32.

상기 에너지 압소버(10)는 빔 결합홈부(14)가 상기 임팩트 빔(20)의 선단부에 면접되고, 도어 밀착부(12)가 도어 아우트 패널(32)에 면접됨과 동시에 수평 방향으로 압력을 가하여 끼워서 고정 설치된다.In the energy absorber 10, the beam coupling groove 14 is interviewed with the front end of the impact beam 20, and the door contact part 12 is interviewed with the door outer panel 32 while applying pressure in a horizontal direction. It is fixed and installed.

첨부된 도면 중 미설명부호 36은 도어 트림이다.Reference numeral 36 in the accompanying drawings is a door trim.

그러면 제2도 및 제3도를 참조하여 본 발명의 효과에 관한 설명하겠다.Next, the effects of the present invention will be described with reference to FIGS. 2 and 3.

도어(30)의 내측 길이방향으로 장착되는 임팩트 빔(20)과 도어 아우트 패널(32) 사이에서 수평 방향으로 압력을 가하여 임팩트 빔(20)과 동일한 방향으로 끼워서 고정되는 에너지 압소버(10)에 의해 자동차의 측면 충돌 사고시 도어 아우트 패널(32)로부터 자동차 실내로 전달되는 충격을 1차적으로 충격흡수 능력이 우수한 에너지 압소버(10)가 흡수 완화시킴과 동시에 허니컴 및 삼각형상의 중공부(16, 161)에 의해 저감시키고, 이어서 충격에 따른 강도가 우수한 임팩트 빔(20)이 전달되는 잔류 충격을 흡수 완화시켜 도어(30)가 자동차 실내로 침입하는 것을 방지하게 되는 것이다.Between the impact beam 20 mounted in the inner longitudinal direction of the door 30 and the door outer panel 32 in the horizontal direction by applying pressure in the same direction as the impact beam 20 to the energy absorber 10 is fixed The energy absorber 10, which has excellent shock absorption ability, primarily absorbs the shock transmitted from the door outer panel 32 to the interior of the vehicle in the event of a side collision of the vehicle, and at the same time, the honeycomb and the triangular hollow portion 16,161. ), And then absorb and mitigate the residual shock transmitted by the impact beam 20 having excellent strength according to the impact, thereby preventing the door 30 from entering the vehicle interior.

상기 임팩트 빔(20)은 금속 재질로 성형되어 측면 충돌에 따른 충격에 대한 내충격성을 발휘하게 되는 것이고, 더욱이 이 임팩트 빔(20)에 가해지는 충격은 전방에 위치하는 에너지 압소버(10)에 의해 충격이 흡수되어 저감되므로 보다 효과적으로 안전하게 자동차 실내의 탑승자를 보호할 수 있는 것이다.The impact beam 20 is formed of a metal material to exhibit impact resistance against impact due to side impact, and furthermore, the impact beam 20 is applied to the energy absorber 10 located in front of the impact beam 20. Since the shock is absorbed and reduced, it is possible to more effectively and safely protect the occupants of the vehicle interior.

이상과 같이 본 발명은 자동차 도어의 이너 패널에 가로방향으로 장착되는 임팩트 빔과 도어 외측 패널 사이에 충격흡수 능력 및 충격 저감 기능이 우수한 재질로된 에너지 압소버를 수평방향으로 압력을 가하여 끼워 결합되게 함으로써, 자동차의 측면 충돌에 대한 충격흡수 및 저감능력을 증대시켜 자동차 실내의 탑승자를 측면 충돌 사고로부터 보다 안전하게 보호할 수 있는 것이다.As described above, the present invention is fitted between the impact beam mounted on the inner panel of the automobile door in the horizontal direction and an energy absorber made of a material having excellent shock absorbing ability and shock reduction function in a horizontal direction to be fitted into the door. By doing so, it is possible to more safely protect the occupants of the vehicle interior from the side collision accident by increasing the shock absorption and reduction capacity for the side collision of the vehicle.
