본 고안은 자동차의 후방도어에 취부되는 임팩트바에 관한 것으로서, 특히, 임팩트바의 구조를 개선하여 충돌시 전달되어 오는 충격 에너지를 효율적으로 분산처리하여 완화되도록하고 또한 임팩트바의 강성이 향성되도록 하는 자동차용 도어 임팩트바 구조에 관한 것이다.The present invention relates to an impact bar mounted on a rear door of an automobile, and in particular, to improve the structure of the impact bar to efficiently dissipate the impact energy transmitted during a collision so as to be alleviated, and also to increase the rigidity of the impact bar. It relates to a door impact bar structure.

일반적으로 자동차용 후방도어 임팩트바구조는 차량의 측면충돌시와 같이 도어가 파손되는 경우 임팩트바가 파손된 도어 외측판넬의 진입을 억제하고 충격에너지를 효과적으로 완충하여 승객의 안전성을 확보하기 위해 제작되는데 종래의 자동차용 도어 임팩트바의 구조는 제1도와 제2도에 도시되는 바와 같이 내측판넬(1)와 외측판넬(2)이 절곡되어 소정의 폐공간을 형성하는 도어(3) 의 내측에 일측은 도어(3)의 선단에 형성되어 있는 힌지(4)의 사이에 설치하고 일측은 도어록크(7)장치부위의 하단부로 각기 정션(junction)(5)이 용접에 의해 내측판넬(1)에 부착되고, 상기 정션(5)에 원형임팩트바(6)의 양단부가 지짇되도록 용착되어, 차량의 측면충돌등의 사고로 도어(3)가 파손되는 경우 상기 임팩트바(6)가 파손된 도어(3)외측판넬(2)의 진입을 억제하고 충격에너지를 흡수하여 실내에 승차한 승객을 보호하도록 되어있다.In general, the rear door impact bar structure for automobiles is manufactured to prevent the entry of the outer panel of the door where the impact bar is damaged in case the door is damaged, such as in the case of side collision of the vehicle, and to buffer the impact energy effectively to ensure passenger safety. As shown in FIG. 1 and FIG. 2, the inner side of the door 3 which is bent by the inner panel 1 and the outer panel 2 to form a predetermined closed space, as shown in FIGS. It is installed between the hinges 4 formed at the front end of the door 3, and one side is a lower end of the device of the door lock 7, and each junction 5 is attached to the inner panel 1 by welding. And the both ends of the circular impact bar 6 are welded to the junction 5 so that the impact bar 6 is broken when the door 3 is damaged by an accident such as a side collision of the vehicle. Suppresses the entry of the outer panel (2) and fills it. To absorb energy is to protect a passenger riding in the room.

그러나 이러한 종래의 자동차용 후방도어 임팩트바의 취부구조는 상기 도어 내측에 양측으로 취부된 정션(5)으로 단순히 임팩트바(6)양측단을 수평으로 용접설치한 구조로 되어 있어 상기 임팩트바의 미강성으로 인해 사고발생시 측면에서 가해지는 충격에너지를 효율적으로 분산처리하여 완화시키지 못하게 되는 문제점이 있었다.However, the conventional mounting structure of the rear door impact bar for a vehicle is a junction 5 mounted on both sides inside the door, and has a structure in which only two impact bars 6 are horizontally welded and installed. Due to stiffness, there was a problem in that the impact energy applied from the side in case of an accident could not be effectively dispersed and mitigated.

이에 본 고안은 상기와 같은 문제점을 감안하여 안출한 것이로서, 상기 임팩트바를 구성하는데 있어 임팩트바를 차량의 측면 충돌시 효과적으로 충격을 분산처리하여 완충할 수 있도록 개선하여 결과적으로는 승객의 안전성이 향상되도록 하는 자동차용 후방도어 임팩트바구조를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the above problems, and in constructing the impact bar, the impact bar is improved to effectively absorb and cushion the impact during side impact of the vehicle, and consequently to improve the safety of the passenger. The purpose is to provide a rear door impact bar structure for a vehicle.

이러한 본 고안의 목적은 내측판넬과 외측판넬이 소정의 간격을 두고 폐공간을 형성하는 도어에 있어서, 상기 도어의 내측에 용착되는 정션의 일측은 도어의 선단에 형성되어 있는 상당힌지 부위에 설치하고 타측은 도어록크장치부위에 설치하며 또다른 일측은 도어록크장치부위의 하단에 설치하여 장축으로 형성된 임팩트바는 상기 상단 힌지부위와 도어록크장치부위에 설치된 정션에 수평으로 양측을 용접설치하고, 단축으로 형성된 임팩트바의 일측은 상기 도어록크 하단에 설치된 정션에 용접설치하며, 일측은 상단에 수평으로 연결설치되는 장축임팩트바의 중앙에 용착되도록 구성하여 달성될 수 있다.The object of the present invention is that in the door in which the inner panel and the outer panel to form a closed space at a predetermined interval, one side of the junction welded to the inner side of the door is installed in the corresponding hinge portion formed at the front end of the door The other side is installed at the door lock device part and the other side is installed at the bottom of the door lock device part, and the impact bar formed by the long axis is welded and installed both sides horizontally to the junction installed at the upper hinge part and the door lock device part. One side of the impact bar formed by welding is installed in the junction installed at the bottom of the door lock, one side may be achieved by being configured to be welded to the center of the long axis impact bar is installed horizontally connected to the top.

In addition, one side of the junction 30a welded to the inner panel 11 located in the closed space of the door 10 is installed between the hinge 13 formed at the tip of the door 10 and the other side is the door lock. (14) is installed on the device portion and the other side is installed at the bottom of the door lock (14) device, the impact bar (20a) formed in the long axis is installed between the hinge 13 and the door lock (14) device portion Both ends are welded to the junction 30b, and one side of the impact bar 20b formed as a short axis is welded to the junction 30c installed at the bottom of the door lock 14 device, and the other side is connected to the top horizontally. It is formed to be welded to the center of the impact bar 20a. Meanwhile, the junction 30a for joining the front end of the long axis impact bar 20a is formed in multiple stages, and one side is provided with a recessed groove 13 to mount one side of the impact bar 20a formed with the long axis. One side is formed to install the upper end hinge 13 of the door 10.

또한, 상기 장축 임팩트바(20a)의 후단을 접합하는 정션(30b)은 다단절곡되어 일측은 상기 장축으로 형성된 임팩트바(20a)의 일측을 취부할 수 있도록 요입홈(21)을 구비하여 또다른 일측은 도어록크(14)장치를 설치할 수 있도록 형성되어 있다.In addition, the junction 30b for joining the rear end of the long axis impact bar 20a is bent in multiple stages so that one side is provided with a recessed groove 21 to mount one side of the impact bar 20a formed by the long axis. One side is formed to install the door lock 14 device.

그리고, 상기 도어(10)내측에 설치되는 단축으로 형성된 임팩트바(20b)의 선단 일측은 함몰부(22)를 형성하여 장축으로 형성된 임팩트바(20a)의 일측면에 용착이 용이하도록 구성되어 있다.In addition, one end of the impact bar 20b formed by a short axis installed inside the door 10 is configured to form a depression 22 to facilitate welding on one side of the impact bar 20a formed by the long axis. .

이와 같은 구성되는 본 고안은 도어(10)내측에 장축으로 형성된 임팩트바(20a)를 수평으로 연결설치하고 단축으로 형성된 임팩트바(20b)를 수직으로 상호연결 설치하여 측면 충돌 발생시 차체에 전달 되어오는 충격에너지를 효율적으로 분산처리하여 충격을 완화시킬 수 있으며 또한, 충격을 완충하여 주는 임팩트바(20)의 완층부위가 확장되게 형성하여 응력분포가 균일하고도 폭넓게 되고 상기 임팩트바(20)를 용착하는 정션(30b)을 설치부위의 부품과 통합할 수있도록 변형하여 효율성을 향상시킬 수 있도록 한 것이다.The present invention, which is configured as described above, is installed horizontally connecting the impact bar 20a formed with the long axis inside the door 10 and vertically connecting the impact bar 20b formed with the short axis to be transmitted to the vehicle body when a side collision occurs. The impact energy can be effectively dispersed and the impact can be alleviated, and the complete portion of the impact bar 20 which buffers the impact is formed to be expanded so that the stress distribution is uniform and wide, and the impact bar 20 is welded. The junction (30b) is to be modified to be integrated with the components of the installation portion to improve the efficiency.

따라서, 앞에서 설명한 바와 같이 본 고안은 도어 내측에 장축과 단축으로 형성된 임팩트바를 수평과 수직으로 상호연결 설치하여 주므로 차량의 측면 충돌시 발생되는 충격에너지를 효과적으로 분산처리하여 충격을 완화시킬 수 있어, 결과적으로는 승객의 안전성이 향상되도록 한 효과를 가지게 되는 것이다.Therefore, as described above, the present invention provides an impact bar formed with a long axis and a short axis interconnected horizontally and vertically inside the door, thereby effectively distributing impact energy generated during side impact of the vehicle, thereby alleviating the impact. This will have the effect of improving the safety of the passengers.
