Description

자동차의 센터필러 밀림방지구조Center pillar rolling prevention structure of car

본 고안은 자동차의 사이드 임팩트(SIDE IMPACT)시에 도어의 실내 침입을 저지시키는 자동차의 센터필러 밀림방지구조에 관한 것으로, 보다 구체적으로는 센터필러의 내부에 사이트 임팩트시 외부 충돌에 대하여 충분한 버팀력을 제공하는 밀림방지구조를 설치하여서 자동차의 측면 충돌시에 도어의 실내 침입량을 감소시켜서 탑승자에게 안전성을 부여하도록 하는 개선된 형태의 사이트임팩트시 완충용 보강구조에 관한 것이다.The present invention relates to a center pillar anti-rolling structure of a vehicle which prevents intrusion of a door into a room during side impact of a vehicle, and more specifically, sufficient support against external collision during site impact inside a center pillar. The present invention relates to a reinforcement structure for shock absorbing at the time of impact of an improved form to provide safety to the occupant by installing an anti-roll structure to provide a reduction in the amount of indoor penetration of the door during the side collision of the car.

일반적으로 자동차의 전,후방에는 불의의 충돌 및 추돌사고에 대비하여 탑승자의 안전을 도모하는 다양한 형태의 안전장치가 마련되어 있다.In general, various types of safety devices are provided in the front and rear of a car to protect the occupant's safety in case of an unexpected collision and a collision accident.

자동차의 전,후방에 완충용 범퍼를 설치하거나, 엔진이 뒤쪽으로 밀리는 것을 방지되도록 엔진룸 내부에 임팩트바나 보강판넬을 설치하거나, 양쪽 도어의 내부에 임팩트바를 설치하거나, 그 밖에도 운전자나 뒤쪽 탑승자의 외부충격을 완화하기 위하여서 다양한 형태의 보강판넬이 설치되어 있다.Install shock absorbers in the front and rear of the car, install impact bars or reinforcement panels inside the engine room to prevent the engine from being pushed backwards, or install impact bars in the interior of both doors. Various types of reinforcement panels are installed to mitigate external shocks.

자동차의 양쪽 도어는 도어글라스가 승,하강할 수 있도록 일정한 두께를 가지고 있고, 또한 도어의 내부에 별도의 임팩트바가 설치되어 있어서 자동차 사이드 임팩트시에 탑승자를 보호하도록 하고는 있으나 도 1 에 도시한 바와 같이 자동차 도어(9,10)들이 서로 맞닿는 부분의 센터필러에는 별도의 센터필러 밀림방지구조가 구비되어 있지 않아서 자동차의 사이드 임팩트시에 충분한 버팀력을 제공할 수가 없었고, 또한 도어 해당 부위의 실내 침입량을 현저히 줄여줄 수가 없으므로 자동차 측면충돌시에 탑승자에게 외부의 충돌에너지가 그대로 전달이 되어서 부상 정도를 획기적으로 줄여줄 수 없는 단점이 있었다.Both doors of the car have a certain thickness so that the door glass can move up and down, and a separate impact bar is installed inside the door to protect the occupants during the impact of the car, but as shown in FIG. Similarly, the center pillar at the part where the doors 9 and 10 abut each other is not provided with a separate center pillar roll preventing structure, and thus, it is not possible to provide sufficient support force at the side impact of the car, and also to penetrate the interior of the door part. Since the amount cannot be significantly reduced, the external collision energy is transferred to the occupant as it is during the side collision of the vehicle, which can not significantly reduce the degree of injury.

본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 자동차의 도어들이 서로 맞닿는 부분의 박스 형태로 된 센터필러 내부에 사이드임팩트시 센터필러 밀림방지구조를 설치하여서 외부 충돌시에 충돌에너지에 대한 충분한 버팀력과, 완충력을 제공하여서 안전한 차체 구조를 제공하도록 하는 것이다.The present invention has been devised to solve the above problems, by installing a center pillar push prevention structure at the side impact inside the box-shaped center pillar of the car doors in contact with each other to prevent collision energy in the event of an external collision It provides enough support and cushioning force to provide a safe body structure.

상기와 같은 목적을 달성하기 위한 본 고안의 자동차 센터필러 밀림방지구조는 박스 형태로 된 센터필러의 내부에 보강패널과 보강브라켓트를 설치하고, 상기한 보강패널과 보강브라켓트의 중단에는 돌출된 완충턱을 형성하며, 상기한 보강브라켓트 완충턱의 이면홈에는 완충용패드를 설치하여서 자동차의 측면 충돌시에 충돌에너지를 보다 효과적으로 흡수,완화하여서 탑승자의 부상정도를 획기적으로 줄일 수 있도록 하였다.The vehicle center pillar rolling prevention structure of the present invention for achieving the above object is installed in the box-shaped center pillar inside the reinforcement panel and the reinforcement bracket, protruding buffer jaw at the interruption of the reinforcement panel and the reinforcement bracket. By forming a buffer pad in the back groove of the cushioning bumper of the reinforcement bracket, the collision energy of the vehicle can be more effectively absorbed and alleviated during side impact of the vehicle, thereby significantly reducing the injuries of the occupants.

도 2 에서,In Figure 2,

부호 1 은 본 고안의 자동차의 센터필러 밀림방지구조를 표시하며; 상기한 밀림방지구조(1)는 자동차의 도어들이 서로 맞닿는 지점의 박스 형태로 된 센터필러(3) 내부에 설치되어서 외부의 충돌에너지를 흡수하도록 되어 있다.Reference numeral 1 denotes a center pillar anti-rolling structure of the vehicle of the present invention; The anti-rolling structure 1 is installed inside the center pillar 3 in the form of a box at the point where the doors of the vehicle abut each other so as to absorb external collision energy.

상기한 밀림방지구조(1)는 박스 형태로 된 센터필러(3)내부의 외측단에 설치되는 보강패널(4)과, 그 내측에 설치되는 보강브라켓트(5)로 구성되어 있고; 상기한 보강패널(4)과 보강브라켓트(5)의 중단에는 돌출된 완충턱(6,7)을 각각 형성하며; 상기한 보강브라켓트(5) 완충턱(7)의 이면홈에는 완충용패드(8)를 설치하여서 된 것이다.The rolling prevention structure (1) is composed of a reinforcement panel (4) installed at the outer end of the inner center pillar (3) in the form of a box, and a reinforcement bracket (5) installed at the inside thereof; At the middle of the reinforcement panel 4 and the reinforcement bracket 5, protruding buffer jaws 6 and 7 are formed, respectively; The rear surface of the reinforcing bracket (5) buffer jaw (7) is to install a buffer pad (8).

이와같이 구성된 본 고안의 자동차 센터필러 밀림방지구조(1)는 자동차 도어들이 서로 맞닿는 지점의 박스 형태로 된 센터필러(3) 내부에 설치된 상태에서 도어 외부에 측면충돌이 발생할 때에는 먼저 도어인너판넬(2)이 실내로 침입하고, 이와 동시에 센터필러(3)에 외부의 충돌에너지가 그대로 전달이 된다.The vehicle center pillar rolling prevention structure 1 of the present invention configured as described above has a door inner panel 2 when a side collision occurs outside the door in a state where the vehicle doors are installed inside the box-shaped center pillar 3 at the point where the doors contact each other. ) Penetrates into the room, and at the same time, external collision energy is transmitted to the center pillar 3 as it is.

그러므로 센터필러(3)의 내부에 설치된 본 고안의 밀림방지구조(1)가 충돌에너지에 대항하면서 보강패널(4)이 실내쪽의 보강브라켓트(5)쪽으로 밀리고, 이 보강패널(4)의 완충턱(6)이 보강브라켓트(5)의 완충턱(7)에 맞닿으면서 이들이 서로 찌그러지면서 충돌에너지가 완화된다.Therefore, the reinforcement panel 4 is pushed toward the reinforcement bracket 5 in the room side while the anti-rolling structure 1 of the present invention installed inside the center pillar 3 is opposed to the collision energy, and the reinforcement panel 4 is fully cushioned. As the jaw 6 abuts against the buffering jaw 7 of the reinforcing bracket 5, they are crushed with each other, thereby alleviating the collision energy.

그리고, 상기한 보강패널(4)과 보강브라켓트(5)가 본격적으로 서로 맞닿아 충돌에너지가 흡수되면서 상기한 보강브라켓트(5)의 완충턱(7) 이면홈에 설치된 완충용패드(8)에 의하여 다시 한번 충돌에너지가 흡수되어서 실내의 탑승자에게 전달되는 외부의 충돌에너지가 극소화 되도록 한다.In addition, the reinforcement panel 4 and the reinforcement bracket 5 are in contact with each other in earnest, so that the collision energy is absorbed, and the shock absorbing pad 8 installed in the back recess of the buffering jaw 7 of the reinforcement bracket 5 is absorbed. By the collision energy is absorbed once again to minimize the external collision energy delivered to the passengers in the room.

따라서, 상기에 설명한 바와 같이 자동차의 사이드임팩트시 도어의 측면 부위에 가해지는 충돌에너지를 다단계로 흡수, 완화시켜서 도어의 실내 침입량을 줄여서 최종적으로는 실내의 탑승자에게 최소의 에너지만이 전달되도록 하므로써, 탑승자의 신체에 전해지는 충돌에너지를 감소시켜서 탑승자의 부상 정도를 현저히 줄여주는 것이다.Therefore, as described above, by absorbing and mitigating the collision energy applied to the side part of the door in the side impact of the car in multiple stages, the amount of indoor penetration of the door is reduced so that only the minimum energy is delivered to the passengers in the room. In addition, the collision energy transmitted to the occupant's body is reduced to significantly reduce the occupant's injury.

이상에서 살펴본 바와 같이 본 고안은 자동차의 센터필러 내부에 외부의 충돌에너지를 다단계로 흡수, 완화시키는 밀림방지구조를 설치하므로써, 도어의 사이드임팩트시에 해당 부위의 실내 침입량을 획기적으로 줄여서 실내 탑승자의 신체에 전해지는 충돌에너지를 급격히 감소시켜 탑승자의 부상 정도를 현저히 줄여주는 제반 특, 장점이 있다.As described above, the present invention installs a jungle prevention structure that absorbs and mitigates external impact energy in multiple stages inside the center pillar of the vehicle, thereby significantly reducing the indoor intrusion amount of the corresponding area during the side impact of the door. There is a special feature and advantage that drastically reduces the collision energy transmitted to the body of the rider and significantly reduces the injuries of the occupants.
