Description

자동차 도어의 보강구조Reinforcement structure of car door

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

본 고안은 자동차의 도어(DOOR)의 보강구조에 관한 것으로서, 더욱더 상세히게는 도어의 강성을 향상시켜 차내에 탑승한 승원의 안전성이 향상되도록 하는 자동차 도어의 보강구조에 관한 것이다.The present invention relates to a reinforcement structure of a door of a vehicle, and more particularly to a reinforcement structure of a car door to improve the rigidity of the door to improve the safety of the occupant in the vehicle.

종래 자동차 도어의 보강구조는 제1도와 제2도에 도시하고 있는 바와 같이, 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 형성하는 도어(10)의 내측 공간부에 임팩드바(20:IMPACT BAR)의 양측단부가 정션(30:JUNCTION)에 의해 외측판넬(12)에 지지되어 있다.As shown in FIG. 1 and FIG. 2, the reinforcing structure of a conventional automobile door has an impact on the inner space of the door 10 in which the inner panel 11 and the outer panel 12 are bent to form a predetermined space. Both ends of the draw bar 20 (IMPACT BAR) are supported by the outer panel 12 by the junction 30: JUNCTION.

이러한 종래 자동차 도어의 보강구조는, 차량의 측면부 충돌과 같은 사고로 도어(10)가 파손되는 경우, 임팩드바(20:IMPACT BAR)가 파손된 도어(10)의 공간 내부로 외측판넬(12) 진입을 억제하고 충격에너지를 흡수하여 실내에 승차한 승원을 보호하도록 되어 있다.The conventional reinforcement structure of the door of the vehicle, the outer panel 12 into the space of the door 10 in which the impact bar 20 (IMPACT BAR) is damaged, if the door 10 is broken by an accident such as a side collision of the vehicle. It is supposed to protect the occupants in the room by suppressing entry and absorbing the impact energy.

그러나, 이러한 종래 자동차 도어의 보강구조는 제2도에 도시되는 바와 같이, 원형단면의 원통형 봉으로 형성된 임팩드바(20)가 반원단면의 요홈부가 형성된 정션(30:JUNCTION)에 양단부의 외주면이 밀착되며 외측판넬(12)에 용접에 의해 고정되는 것에 의해서만 충격에너지의 흡수가 이루어짐으로서, 상기 임팩드바(20)에 일정 이상의 충격이 가해지는 경우, 상기 충격에너지에 의해 외측판넬(12)로 부터 임팩드바(20)가 이탈됨으로서, 파손된 도어(10)의 외측판넬(12)이 차실로 유입되는 것을 억제하지 못하게되어 차내에 탑승한 승원이 부상을 입게 되는 문제점이 있었던 것이다.However, in the reinforcing structure of the conventional automobile door, as shown in FIG. When the impact energy is absorbed only by being fixed to the outer panel 12 by welding, when a predetermined or more impact is applied to the impact bar 20, the impact energy is impacted from the outer panel 12 by the impact energy. As the debar 20 is separated, the outer panel 12 of the damaged door 10 may not be prevented from flowing into the vehicle compartment, and the occupant in the vehicle may be injured.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 임팩트바가 설치된 도어의 공간부 내측면에 일측단부가 내측판넬에 취부되고, 타측단부는 임팩트바를 감싸는 취부브라켓에 취부되어 폐단면이 형성되는 취부브라켓을 취부하며, 충돌사고에 의해 임팩드바가 도어의 내측면에서 분리되는 것을 억제하고, 상기 충격에너지를 중간기둥 및 차체로 전달하여 도어의 외측판넬이 외부충격에 의해 차실로 유입되는 것을 억제하며, 차실에 탑승한 승원의 안전성이 향상되도록 하는 자동차 도어의 보강구조를 제공하는 데 있다.The purpose of the present invention is to solve the conventional problems as described above, one end is mounted on the inner panel of the inner space of the space portion of the door is installed impact bar, the other end is attached to the mounting bracket surrounding the impact bar is formed closed end surface The mounting bracket is mounted, and the impact bar is prevented from being separated from the inner surface of the door by a collision accident, and the impact energy is transferred to the intermediate pillar and the vehicle body so that the outer panel of the door is introduced into the cabin by the external impact. To suppress and to provide a reinforcement structure of the car door to improve the safety of the occupants in the cabin.

이하, 첨부된 도면에 의하여 본 고안의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention by the accompanying drawings in detail.

본 고안의 자동차 도어의 보강구조도 제3도와 제4도에 도시하고 있는 바와 같이, 내측판넬(11)과 외측판넬(12)이 절곡되어 소정의 공간을 형성하는 도어(10)의 내측 공간 양측부에 각기 임팩드바(20:IMPACT BAR)의 양단부가 정션(30:JUNCTION)에 의해 외측판넬(12)에 지지되어 지는 것은 종래와 같다. 단, 본 고안은 상기 임팩드바(20)를 감싸는 별도의 취부브라켓(40)이 설치되고, 상기 취부브라켓(40)에 일측단부에는 다단으로 절곡 형성된 차체측브라켓(50)의 일측단부가 용착되며, 상기 차체측브라켓(50)의 타측단부는 내측판넬(11)에 폐단면을 갖으며 취부됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 3 and FIG. 4, the reinforcing structure of the automobile door of the present invention, the inner panel 11 and the outer panel 12 are bent to form a predetermined space both sides of the inner space of the door 10 Both ends of the impact bar 20 (IMPACT BAR) are supported on the outer panel 12 by the junction 30 (JUNCTION), respectively. However, the present invention is provided with a separate mounting bracket 40 surrounding the impact bar 20, one side end of the vehicle body side bracket 50 is formed to be bent in multiple stages on the mounting bracket 40 is welded On the other hand, the other end of the vehicle body side bracket 50 has a closed cross section on the inner panel 11, and is a basic feature of the technical configuration.

이와같이 구성되는 자동차 도어의 보강구조는 차량을 운행중 차량의 측면으로 충격이 가해지는 경우, 도어(10)의 내측 공간부에서 1차적인 충격에너지를 흡수하고, 2차적으로 도어(10)의 공간부에 설치된 임팩드바(20)에서 충격에너지를 흡수하며, 3차적으로 임팩트바(20)를 감싸며 설치된 취부브라켓(40)의 단부에 일측단부가 취부되고, 타측단부가 내측판넬(11)에 취부되어 도어(10)의 내부공간부에 별도의 폐단면을 형성하는 차체측브라켓(50)에 의해 충격에너지가 흡수 및 차체측으로 분산되어 진다.The reinforcement structure of the automobile door configured as described above absorbs primary impact energy in the inner space of the door 10 when the impact is applied to the side of the vehicle while the vehicle is being driven, and secondly, the space of the door 10. The impact bar absorbs the impact energy from the impact bar 20 installed at the third side, and one end portion is mounted at the end of the mounting bracket 40 installed to surround the impact bar 20 and the other end portion is mounted at the inner panel 11. Impact energy is absorbed and dispersed to the vehicle body side by the vehicle body side bracket 50 forming a separate closed section in the inner space of the door 10.

따라서 이러한 본 고안은 차량의 측면으로 충격이 가해지는 경우에도 도어(10)의 내측 공간부로 외측판넬(12)이 변형되어 차체로 밀려들어오는 것이 억제됨으로서 차실에 탑승한 승원의 부상당하는 것을 억제하게 됨은 물론, 도어(10)의 강성이 향상되어 차량의 상품성이 향상되도록 하는 효과가 있다.Therefore, the present invention is suppressed from being pushed into the vehicle body by deforming the outer panel 12 into the inner space portion of the door 10 even when an impact is applied to the side of the vehicle to suppress the injuries of the occupants in the cabin. Of course, the rigidity of the door 10 is improved, thereby improving the merchandise of the vehicle.

이상에서 살펴본 바와 같이, 본 고안은 임팩드바(20:IMPACT BAR)가 외부의 충격에 의해 도어로부터 분리되는 것을 억제하여 차실에 탑승한 승원의 안전성이 향상되도록 하는 매우 유용한 고안인 것이다.As described above, the present invention is a very useful design to improve the safety of the occupant in the cabin by preventing the impact bar (20: IMPACT BAR) from being separated from the door by an external impact.
