본 고안은 승용차에 측면충돌이 가해질 때 그 충격에너지를 도어내에서 흡수하도록 하는 승용차 도어의 측면충돌 보강구조에 관한 것이다.The present invention relates to a side collision reinforcement structure of a passenger car door to absorb the impact energy in the door when a side collision is applied to the car.

종래의 승용차 도어에는 제 4 도와 같이 도어외측패널(21) 내면과 접하는 임팩트 바(22)를 도어 하부측에 가로질러 설치하고 있었다.The conventional passenger car door is provided with an impact bar 22, which is in contact with the inner surface of the door outer panel 21, across the lower door side as in the fourth diagram.

상기 임팩트 바(22)는 대차(23)가 화살표 방향으로 측면충돌할 경우에 그 충격에너지를 흡수하는 기능을 수행하지만 임팩트 바(22)가 탄성한도 이상의 충격하중을 받게 되면 쉽게 휘어져 들어가지 때문에 가상선 표시와 같이 도어외측패널(21)은 물론 도어내측패널(24)과 사이드 씰(25)까지 변형되면서 실내로 밀려들어와 차체의 큰 손상은 물론 실내의 승객 상해치가 그 만큼 높아지는 문제가 있는 것이다.The impact bar 22 functions to absorb the impact energy when the trolley 23 collides in the direction of the arrow, but the impact bar 22 is easily bent when the impact bar 22 receives an impact load greater than the elastic limit. As shown by the line display, the door outer panel 21, as well as the door inner panel 24 and the side seal 25 is deformed and pushed into the room, causing a great damage to the vehicle body as well as the passenger injury in the room.

이를 해결하기 위해서는 충격하중이 가해지는 부위에 강성을 높여야 하고, 이러한 강성의 높힘에 있어서도 충격에너지를 흡수할 수 있어야 승객 상해치를 극소화할 수 있는 것이다.In order to solve this problem, the rigidity must be increased at the site where the impact load is applied, and even when the rigidity is increased, the impact energy can be minimized to minimize the passenger injury.

본 고안의 목적은 측면충돌에 대한 도어의 강성을 높여 차체의 변형을 방지하고 동시에 충격에너지의 흡수가 유리한 구조를 취하여 승객을 보호코자 하는데 있는 것이다.The purpose of the present invention is to protect the passengers by increasing the rigidity of the door against side collisions to prevent the deformation of the vehicle body and at the same time take advantage of the absorption of impact energy.

본 고안은 상기 목적을 달성하기 위하여, 중간부위가 도어외측패널과 접하도록 단차를 이루는 단면형상의 제 1 보강부재를 측면충돌에 대한 충격에너지의 1차 흡수가 가능하게 임팩트 바와 도어내측패널의 하단부에 용접하고, 서로 장구형의 단면형상을 이루며, 용접되는 제 2 보강부재와 제 3 보강부재를 측면충돌에 대한 충격에너지의 2차 흡수가 가능하게 상기 제 1 보강부재의 후면과 이격되는 위치에서 상기 도어내측패널 측면에 용접한 것이다.In order to achieve the above object, the present invention provides a first reinforcing member having a stepped shape so that an intermediate portion contacts a door outer panel so as to enable primary absorption of impact energy against side impacts. And the second reinforcing member and the third reinforcing member are welded to each other to form a cross-sectional shape of each other, and are spaced apart from the rear surface of the first reinforcing member to enable secondary absorption of impact energy against side impacts. It is welded to the side of the inner panel of the door.

이하 본 고안의 실시예를 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.

본 고안은 제 1 도와 같이 차량의 도어(B) 하부에 도어(B)의 길이방향, 즉 횡방향으로 적용된다.The present invention is applied in the longitudinal direction, that is, the transverse direction of the door (B) under the door (B) of the vehicle as the first diagram.

본 고안은 제 2 도와 같이 도어외측패널(1) 내면과 접하는 임팩트 바(2)가 가로질러 설치된 것에 있어서, 중간부위가 도어외측패널(1)과 접하도록 경사진 단차를 이루며 돌출하는 단면형상의 제 1 보강부재(3)를 임팩트 바(2)와 도어내측패널(4)의 하단부에 용접하고, 서로 장구형의 단면형상을 이루도록 경사진 단차를 중간부위에 형성한 후 대칭되게 용접된 제 2 보강부재(5)와 제 3 보강부재(6)를 제 1 보강부재(3)의 후면과 이격되는 위치에서 임팩트 바(2)와 도어내측패널(4) 하단 사이의 공간을 점유하도록 도어내측패널(4) 측면에 용접한 것이다.The present invention is that the impact bar (2) in contact with the inner surface of the door outer panel (1) is installed across, as shown in the second diagram, the intermediate portion protrudes in a stepped shape inclined step so as to contact the door outer panel (1) The first reinforcing member (3) is welded to the lower end of the impact bar (2) and the door inner panel (4), and the second step is formed symmetrically welded to form an inclined step in the middle of each other to form a long cross-sectional shape The door inner panel to occupy the space between the impact bar 2 and the lower end of the door inner panel 4 at a position where the reinforcing member 5 and the third reinforcing member 6 are spaced apart from the rear surface of the first reinforcing member 3. (4) It is welded to the side.

상기 제 1 보강부재(3)의 일단은 임팩드 바(2)를 감싸면서 용접되고 타단은 도어외측패널(1)과 도어내측패널(4)의 끝말이부분 쪽에서 도어내측패널(4)의 단차를 이루는 측면에 용접된다.One end of the first reinforcing member (3) is welded while wrapping the impact bar (2), and the other end of the door inner panel (4) at the end of the door outer panel (1) and the door inner panel (4) Welded to the side to form.

상기 제 2 보강부재(5)와 제 3 보강부재(6)는 일측에 각각 플랜지를 형성하여 이 플랜지를 도어내측패널(4) 내면에 용접시킨 것이다.The second reinforcing member 5 and the third reinforcing member 6 are each formed with a flange on one side and welded to the inner surface of the door inner panel 4.

미설명부호 7은 사이드 씰(side sill)이다Reference numeral 7 is a side sill.

따라서, 제 4 도와 같은 조건으로 대차(23)가 측면충돌하게 되면 제 3 도와 같이 변형하게 되는데, 임팩트 바(2)가 약간 들어가면서 도어외측패널(1)이 임팩트 바(2) 설치 밑부분이 꺾여 들어가게 된다.Therefore, when the trolley 23 collides sideways under the same conditions as the fourth degree, the third degree is deformed. The impact bar 2 enters slightly, and the door outer panel 1 is bent at the bottom of the impact bar 2 installation. Will enter.

이때 제 1 보강부재(3)는 도어외측패널(1)의 내면에서 밀려 들어오는 도어외측패널(1)의 충격하중에 대한 반력을 작용시켜 측면충돌에 따른 충격에너지를 1차 흡수하게 되고, 이러한 제 1 보강부재(3)에서 흡수되지 않은 잔여 충격에너지는 다시 제 2 보강부재(5)와 제 3 보강부재(6)에 전달되어 제 2 보강부재(5) 및 제 3 보강부재(6)가 변형되면서 흡수하게 된다.At this time, the first reinforcing member 3 acts as a reaction force against the impact load of the door outer panel 1, which is pushed from the inner surface of the door outer panel 1 to absorb the impact energy due to side impacts first. The residual impact energy not absorbed by the first reinforcing member 3 is transmitted to the second reinforcing member 5 and the third reinforcing member 6 again, so that the second reinforcing member 5 and the third reinforcing member 6 are deformed. Absorbed.

이에 따라 실질적으로 제 1 보강부재(3)와 제 2 보강부재(5) 및 제 3 보강부재(6)를 설치하지 않았을 때 보다 도어내측패널(4)과 사이드 씰(7)을 포함하는 차체가 실내로 밀려들어가는 정도는 현저하게 감소되는 것이다.As a result, the vehicle body including the door inner panel 4 and the side seal 7 is substantially lower than when the first reinforcement member 3, the second reinforcement member 5, and the third reinforcement member 6 are not provided. The degree to which they are driven into the room is significantly reduced.

이와 같은 본 고안은 상기와 같이 제 1 보강부재와 제 2 보강부재 및 제 3 보강부재를 임팩트 바 하부의 도어내에 설치하여 측면충돌에 대한 충격에너지를 1, 2차에 걸쳐 흡수시키게 한 것으로서, 차체의 강성을 유지하여 도어가 실내로 밀려들어가지 않게 함으로써 차체의 변형방지와 실내 승객을 보호할 수 있는 효과가 있는 것이다.The present invention as described above is to install the first reinforcing member, the second reinforcing member and the third reinforcing member in the door of the lower impact bar to absorb the impact energy for the side impacts over the first and second, By maintaining the rigidity of the door is not pushed into the room has the effect of preventing the deformation of the body and protect the passengers indoors.
