Description

차량용 도어 임팩트 빔Car door impact beam

본 발명은 차량용 도어 임팩트 빔에 관한 것으로서, 보다 상세하게는 차량의 측면 충돌시 비교적 변형량이 심한 도어 하단부를 보강하는 구조의 임팩트 빔을 제공하여 도어가 차실 내부로 침입하는 것을 줄여줌으로서 승차자의 안전을 도모하기 위한 차량용 도어 임팩트 빔에 관한 것이다.The present invention relates to a door impact beam for a vehicle, and more particularly, to provide a impact beam having a structure that reinforces a lower portion of a door that is relatively deformed during side impact of the vehicle, thereby reducing the intrusion of the door into the interior of the vehicle. It relates to a vehicle door impact beam for planning.

일반적으로 차량의 도어 임팩트 빔은 차량의 도어 패널의 내부에 설치되어 측면 충돌시 도어가 차량의 내부로 침입하는 것을 방지하는 보강부재이다.In general, the door impact beam of the vehicle is a reinforcing member installed in the door panel of the vehicle to prevent the door from entering the interior of the vehicle during side impact.

도어 패널은 도어 인어 패널과 도어 아웃 패널로 이루어지며 그 내부는 수납공간이 형성된다.The door panel includes a door mermaid panel and a door out panel, and an interior of the door panel is formed.

상기한 수납공간에는 도3에서 도시한 바와 같이, 임팩트 빔(10)이 도어의 가로 방향으로 배치되는 구조를 가지며, 상기한 임팩트 빔은 단순한 구조의 중공빔형상으로서, 도어 아웃 패널(20)의 차체 내측에 접착실러(70)에 의해 일차적으로 접착하게 되고, 도어 인어 패널의 수직한 양쪽 가장자리면상에 장착브래킷을 설치하여 이차적으로 고정하여 이루어진다.As shown in FIG. 3, the impact beam 10 has a structure in which the impact beam 10 is disposed in the horizontal direction of the door, and the impact beam has a hollow beam shape having a simple structure. It is primarily bonded by the adhesive sealer 70 to the inside of the vehicle body, and is provided by fixing the secondary by mounting mounting brackets on both vertical edges of the door mermaid panel.

따라서, 측면 충돌에 대하여 충분한 강성을 확보하고, 충격흡수효과를 높이기 위하여 다른 구조의 빔 형상을 연구하게 되었으며, 상기한 바와 같은 도어 임팩트 빔의 형태에 의한 강성의 증대는 임팩트 빔의 크기를 조정하거나, 그의 개수를 증가시키는 방법을 선택할 수 있으나, 이와 같은 방법은 협소한 수납공간내에서는 바람직한 방법이라 할 수 없다.Therefore, in order to secure sufficient stiffness against side impacts and to increase the impact absorption effect, the beam shape of the other structure has been studied, and the increase in rigidity by the shape of the door impact beam as described above may be achieved by adjusting the size of the impact beam. It is possible to select a method of increasing the number thereof, but such a method is not a preferable method in a narrow storage space.

이에, 측면 충돌시 임팩트 빔이 강성을 가지고 지지 역할을 하며, 측면 충격력이 차체에 고르게 분산되도록 하는 다른 구조로서 도어 패널이 차량의 내부로 침입하는 정도를 감소시키는 것이 바람직하다.Therefore, it is desirable to reduce the degree of penetration of the door panel into the interior of the vehicle as another structure that allows the impact beam to have rigidity and support role during side impact, and to distribute the side impact force evenly to the vehicle body.

그러나, 상기한 종래의 차량용 도어 임팩트 빔은, 협소한 공간내에서 단순한 중공빔에 의한 강성의 증대나, 선접촉에의한 지지면의 역할이 충격흡수효과를 증대시키기에는 한계점을 가지고 있다.However, the above-described conventional door impact beams for vehicles have limitations in increasing rigidity by simple hollow beams in a narrow space and increasing the shock absorbing effect by the role of the support surface by line contact.

이에, 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 본 발명의 목적은 차량이 측면 충돌시 비교적 변형량이 심한 도어 하단부의 강성을 증대시키고, 효과적인 충격흡수를 위하여 이중보강구조의 보강부재를 사용함으로서 승차자의 안전을 도모하는 차량용 도어 임팩트 빔을 제공하는데 있다.Accordingly, the present invention has been invented to solve the above problems, an object of the present invention is to increase the rigidity of the lower door portion with a relatively high amount of deformation during side impact of the vehicle, reinforcement member of the double reinforcement structure for effective shock absorption It is to provide a door impact beam for a vehicle to promote the safety of the rider by using.

상기한 본 발명의 목적을 달성하기 위하여, 차량의 측면 충돌시 승차자를 보호하기 위하여 도어의 내부에 설치되는 임팩트 빔에 있어서, 도어 내측에서 차체 길이방향으로 설치되는 고정빔과, 상기 고정빔에 연결수단에 의해서 결합되어 강성을 증대시키는 보강빔과, 상기 결합된 고정빔과 보강빔이 측면 충격력에 대하여 강한 충격 흡수능력을 갖도록 도어 아웃 패널에 부착되는 충격흡수수단을 포함하는 도어 임팩트 빔을 제공한다.In order to achieve the above object of the present invention, in the impact beam installed inside the door to protect the occupant in the event of a side collision of the vehicle, the fixed beam is installed in the vehicle body longitudinal direction from the inside of the door, and connected to the fixed beam It provides a door impact beam comprising a reinforcing beam coupled by the means to increase the rigidity, and the shock absorbing means attached to the door-out panel so that the combined fixed beam and the reinforcing beam has a strong shock absorbing ability to the side impact force. .

도1은 본 발명의 적용 부분을 설명하기 위한 차체의 간략한 사시도로서, 프론트 도어와 리어 도어내에 각각의 고정 브래킷에 의해 차체 길이 방향으로 설치되어 있는 임팩트 빔(1)을 도시하고 있다.Fig. 1 is a simplified perspective view of a vehicle body for explaining the application part of the present invention, showing an impact beam 1 installed in the vehicle body longitudinal direction by respective fixing brackets in the front door and the rear door.

도2는 도1의 A-A선을 따라 본 발명이 적용된 임팩트 빔(1)의 단면도로서, 도어 아웃 패널(7)과 도어 인어 패널(도시하지 않음) 사이에서, 상기 도어 아웃 패널(7)의 내측면에 부착한 임팩트 빔(1)을 도시하고 있다.FIG. 2 is a cross-sectional view of the impact beam 1 to which the present invention is applied along the line AA of FIG. 1, between the door out panel 7 and the door mermaid panel (not shown), the inside of the door out panel 7; The impact beam 1 attached to the side is shown.

상기한 도어 아웃 패널(7)과 도어 인어 패널의 사이에는 수납공간이 형성되고, 상기한 수납 공간내에 상기한 임팩트 빔(1)을 개재하고 있다.A storage space is formed between the door out panel 7 and the door mermaid panel, and the impact beam 1 is interposed in the storage space.

상기한 임팩트 빔(1)은 도2에서 도시한 바와 같이 고정빔(4)과 보강빔(3)은로 구성된다.The impact beam 1 is composed of a fixed beam 4 and a reinforcement beam 3 as shown in FIG.

상기한 고정빔(4)은 중공축부재에 축방향의 내측 선단의 일정부분의 개구부를 형성하고, 여기에 일면이 개방된 보강빔이 연결수단을 가지고 외측으로 결합된다.The fixed beam 4 forms an opening of a predetermined portion of the inner tip in the axial direction in the hollow shaft member, and a reinforcing beam having one side open thereto is coupled to the outside with a connecting means.

상기한 연결수단은 상기 보강빔(3)의 내부에서 상기 고정빔(4)의 개구부를 통하여 고정빔(4)의 중공부에서 결합되도록 연결돌기(5)로 형성된다.The connecting means is formed in the connecting projection 5 to be coupled in the hollow portion of the fixed beam (4) through the opening of the fixed beam (4) inside the reinforcing beam (3).

또한, 상기 보강빔(3)의 개방된 외측 양 끝단에서 상기 도어 아웃 패널(2)의 하단부에 접착실러(7)로서 접착되어 밀착지지하도록 수직 상하로 연장한 충격흡수수단인 밀착지지면(6)을 갖추고 있다.In addition, the contact surface (6) which is a shock absorbing means vertically and vertically extended so as to be adhered to the lower end of the door-out panel (2) to the lower end of the door-out panel (2) at the open outer ends of the reinforcing beam (3) to be in close contact with each other. Equipped)

이와 같이 이루어지는 차량용 도어 임팩트 빔은, 측면 충돌시 도어 아웃 패널(2)에 충격력이 작용하게 되고, 이에 따라 상기 고정빔(4)에 충격력이 전달되어 일차지지하고, 상기한 보강빔(3)에 의해 이차지지하여 강성을 증대시킨다.In the vehicle door impact beam, the impact force is applied to the door-out panel 2 during a side collision, and thus the impact force is transmitted to the fixed beam 4 to be primarily supported, and to the reinforcement beam 3. By secondary support to increase rigidity.

또한 상기한 밀착지지면(6)이 넓은 부분에 대해 지지 역할을 하므로서 충격력을 차체에 고르게 전달하므로서 충격흡수의 효과를 증대할 수 있게되어 도어 패널이 차량의 내부로 침입하는 정도가 감소하게 된다.In addition, since the close contact surface 6 serves as a support for the wide part, the impact force is evenly transmitted to the vehicle body, thereby increasing the effect of shock absorption, thereby reducing the degree of intrusion of the door panel into the vehicle.

상기 본 발명에 따른 임팩트 빔은, 고정빔에 보강빔을 개재하여 강성을 증대시키고, 상기 보강빔에 도어 아웃 패널과의 접촉면을 증가시키는 밀착지지면을 구성하여 충격력을 차체에 고르게 전달하므로서 충격흡수를 극대화할 수 있다.The impact beam according to the present invention is configured to increase the rigidity through the reinforcement beam in the fixed beam, and to form a close contact surface for increasing the contact surface with the door-out panel to the reinforcement beam to transmit the impact force evenly to the vehicle body. Can be maximized.

따라서, 측면 충돌시 도어 패널이 차량 내로 침입하는 정도를 감소시켜 승차자의 안전을 도모할 수 있다.Therefore, it is possible to reduce the extent of the door panel invading into the vehicle during side collisions, thereby making the occupant safe.
