Abstract

PURPOSE: A door beam structure of a vehicle receives external impact with a beam, a door inner panel and a side outer panel, as an integral body, on the occurrence of an impact on the side of the door of a vehicle, thereby preventing the driver and passengers of the vehicle. CONSTITUTION: The gap between a door inner panel(30) and a door outer panel(38) is wide enough for a beam(40) to be attached on a bent portion(34) of the door inner panel. The length of a bracket(44) is made to be short such that the beam is joined with the bracket and both ends of the bracket are welded on the door inner panel. Impact absorbing structures(a,b) are formed for the beam, door inner panel and door outer panel to receive force as an integral body on the side collision of a vehicle.

차량의 도어 빔 구조{Door beam structure of vehicle}Door beam structure of vehicle

본 발명은 도어의 도어 인너 패널과 도어 아웃터 패널의 사이에 설치되는 도어 빔의 구조에 관한 것으로서, 더욱 상세하게는 도어 인너 패널과 도어 아웃터 패널의 사이를 깊게 형성하여 빔을 결합시키고 상기 빔을 결합시키는 빔 브라켓의 양단부를 도어 인너 패널에 직접 용접하도록 구성한 차량의 도어 빔 구조를 제공하는 것이다.The present invention relates to a structure of a door beam installed between a door inner panel and a door outer panel of a door, and more particularly, to deeply form a door inner panel and a door outer panel to couple a beam and to combine the beam. It is to provide a door beam structure of a vehicle configured to weld both ends of the beam bracket to the door inner panel directly.

일반적으로 도어에는 도어 인너 패널과 도어 아웃터 패널의 사이에 빔과 결합된 빔 브라켓을 설치하는데, 종래에는 상기 도어 인너 패널과 도어 아웃터 패널의 사이에 빔이 브라켓에 의해 차체 구조에 걸쳐지는 구조로 형성된다.In general, the door is provided with a beam bracket coupled to the beam between the door inner panel and the door outer panel, conventionally formed between the door inner panel and the door outer panel in a structure in which the beam spans the body structure by the bracket do.

도 1a는 종래의 도어에 설치되는 빔과 빔 브라켓을 결합한 상태를 나타내는 도면이고, 도 1b는 도 1a의 A-A 단면도이다.FIG. 1A is a view illustrating a state in which a beam and a beam bracket are coupled to a conventional door, and FIG. 1B is a cross-sectional view taken along line A-A of FIG. 1A.

차량의 도어(10)에는 그 도어를 구성하는 도어 인너 패널(12)과 도어 아웃터 패널(14)의 사이에 빔(16)의 양측을 고정시킨 빔 브라켓(18)을 연결하여 고정한다. 도 1b의 점선으로 표현한 부분은 용접부(C)를 나타낸다.A beam bracket 18 fixing both sides of the beam 16 is fixed to the door 10 of the vehicle between the door inner panel 12 constituting the door and the door outer panel 14. The part shown with the dotted line of FIG. 1B shows the welding part C. FIG.

상기 도어 인너 패널(12)과 도어 아웃터 패널(14)의 사이에는 도어 아웃터 패널(14)을 형성한 측으로 외부의 충격에 대항할 수 있도록 빔(16)이 형성된다.A beam 16 is formed between the door inner panel 12 and the door outer panel 14 to counter the external impact to the side on which the door outer panel 14 is formed.

종래 도어의 구조는, 도어 인너 패널과 도어 아웃터 패널의 사이에 설치되는 빔과 빔 브라켓이 얹혀지는 구조로 형성되는 관계로 외부에서 충격이 전해지면 빔과 빔 브라켓이 이탈되거나 빔 브라켓과 도어 인너 패널의 용접부가 이탈이되는 문제점이 발생되었고, 특히 도어의 사이드에 충격이 발생되면 빔, 도어 인너 패널, 사이드 아웃터 패널이 충격을 흡수하지 못하는 문제점이 있었다.In the conventional door structure, the beam is installed between the door inner panel and the door outer panel, and the beam bracket is mounted on the door, so that when the impact is transmitted from the outside, the beam and the beam bracket are separated or the beam bracket and the door inner panel are separated. There was a problem that the welding of the separation is a problem, in particular, when the impact occurs on the side of the door, there was a problem that the beam, door inner panel, side outer panel does not absorb the shock.

상술한 문제점을 해결하기 위하여 안출한 본 발명은, 차량 도어의 사이드에 충격이 발생되어도 그 구조상 외부의 충격이 빔, 도어 인너 패널, 사이드 아웃터패널이 일체로 힘을 전달받도록 구성하여 운전자 및 차량의 탑승자들의 안전성을 향상시키도록 하는 차량의 도어 빔 구조를 제공하는 것을 그 목적으로 한다.The present invention devised to solve the above-described problems, even if an impact occurs on the side of the vehicle door, the external impact is configured so that the beam, the door inner panel, the side outer panel is integrally transmitted to the driver and the vehicle by its structure. It is an object of the present invention to provide a door beam structure of a vehicle to improve the safety of occupants.

상술한 목적을 달성하기 위해, 본 발명은, 도어 인너 패널과 도어 아웃터 패널은 그 사이를 빔이 도어 인너 패널의 굴곡부에 밀착될 수 있도록 넓게 형성하고, 빔 브라켓의 길이를 짧게하여 빔을 빔 브라켓과 결합시킴과 아울러 상기 빔 브라켓은 양단부를 직접 도어 인너 패널에 용접하며, 특히 차량에 대한 사이드 충돌시 빔, 도어 인너 패널 및 사이드 아웃터 패널이 일체로 힘을 받도록 충격흡수 구조(a)(b)를 형성한다.In order to achieve the above object, the present invention, the door inner panel and the door outer panel is formed so that the beam is in close contact with the bent portion of the door inner panel, and the length of the beam bracket to shorten the beam bracket In addition, the beam bracket welds both ends directly to the door inner panel, and in particular, the shock absorbing structure (a) (b) so that the beam, the door inner panel and the side outer panel are integrally applied in a side collision with the vehicle. To form.

이하, 첨부 도면을 참조하여 본 발명의 구성과 작용을 설명한다.Hereinafter, the configuration and operation of the present invention with reference to the accompanying drawings.

도 2a는 본 발명의 도어에 설치되는 빔과 브라켓을 결합한 상태를 나타내는 도면이고, 도 2b는 도 2a의 B-B 단면도이다.FIG. 2A is a view illustrating a state in which a beam and a bracket installed in a door of the present invention are combined, and FIG. 2B is a cross-sectional view taken along line B-B of FIG. 2A.

차량의 도어(60)는 도어 인너 패널(30)과 도어 아웃터 패널(38)의 사이에 빔(40)의 양측을 고정하고 있는 빔 브라켓(44)을 용접하는데, 상기 도어 인너 패널(30)과 도어 아웃터 패널(38)의 사이에 설치되는 빔 브라켓(44)은 도어 인너 패널(30)의 굴곡부(34)에 밀착된채로 깊숙히 위치하게 된다. 즉, 상기 도어 인너 패널(30)은 빔 브라켓(44)과 결합되는 주위로 다수의 단을 형성하는 굴곡부(34)를 형성한다.The door 60 of the vehicle welds the beam bracket 44 fixing both sides of the beam 40 between the door inner panel 30 and the door outer panel 38, and the door inner panel 30. The beam bracket 44 provided between the door outer panel 38 is located deep in close contact with the bent portion 34 of the door inner panel 30. That is, the door inner panel 30 forms a bent portion 34 that forms a plurality of stages around the beam bracket 44.

특히, 상기 도어 인너 패널(30)과 도어 아웃터 패널(38)의 공간을 빔(40)이 삽입될 수 있도록 넓게 형성하고 상기 빔(40)의 끝부분을 그 사이에 들어가도록 형성한다.In particular, the space between the door inner panel 30 and the door outer panel 38 is formed wide so that the beam 40 can be inserted, and the end of the beam 40 is formed therebetween.

상기 빔 브라켓(44)은 양옆의 공간을 이용해 빔 브라켓(44)의 측면부(48)를 도어 인너 패널(30)과 직접 용접하여 결합한다.The beam bracket 44 is coupled to the side portion 48 of the beam bracket 44 by directly welding the door inner panel 30 using spaces on both sides thereof.

상기 도어(60)는 외부의 사이드 충격이 발생되면 빔(40), 도어 인너 패널(30), 사이드 아웃터 패널(50)이 구조상 충격흡수 구조(a)(b)로 제작된 관계로 외부의 충격을 그대로 흡수할 수 있게 되는데, 그 이유는 상기 빔(40), 도어 인너 패널(30), 사이드 아웃터 패널(50)이 차량의 사이드 충돌시 그 충격을 그대로 흡수할 수 있도록 적층되는 구조이기 때문이다.When the external side impact occurs, the door 60 has a beam 40, a door inner panel 30, and a side outer panel 50 made of a shock absorbing structure (a) and (b). This can be absorbed as it is, because the beam 40, the door inner panel 30, the side outer panel 50 is a structure that is laminated so that the impact as it is absorbed during the side impact of the vehicle. .

도 2a에 점선으로 원을 나타낸 부분이 도어 인너 패널에 용접되는 부분이다.The part shown by the dotted line in FIG. 2A is the part welded to the door inner panel.

상술한 본 발명의 구성과 작용에 대한 효과를 설명한다.The effect on the structure and operation of the present invention described above will be described.

본 발명의 도어 빔 구조는, 종래와 같이 도어 인너 패널과 도어 아웃터 패널의 사이에 빔 브라켓을 걸쳐지는 구조로 형성하는 것이 아니라 빔, 도어 인너 패널, 사이드 아웃터 패널에 일체로 힘이 작용하도록 구조를 형성한 관계로 외부 충격에 대하여 적절히 대항할 수 있으므로 운전자 및 차량의 탑승자들의 안전성을 향상시키는 효과를 가진다.The door beam structure of the present invention is not formed as a structure that spans the beam bracket between the door inner panel and the door outer panel as in the prior art, but the structure so that the force acts integrally on the beam, the door inner panel and the side outer panel. The formed relationship can be appropriately countered to the external impact, thereby improving the safety of the driver and the occupants of the vehicle.

또한, 상기 도어의 내부 구조는, 도어 인너 패널에 빔이 직접 마운팅되도록 빔 브라켓의 구조를 짧게 형성하여 외부 충격시 보디 구조와 오버랩되는 양이 많아져 사이드 충격에 강한 구조를 이루게 된다.In addition, the inner structure of the door, the structure of the beam bracket to form a short so that the beam is mounted directly on the door inner panel to increase the amount of overlap with the body structure during an external impact to achieve a structure that is resistant to side impact.
