Description

자동차 도어 임팩트빔의 취부구조Mounting Structure of Automobile Door Impact Beam

본 발명은 자동차 도어 임팩트빔의 취부구조에 관한 것으로서, 더 상세하게는 자동차 도어의 내측패널에 양측단이 취부되는 임팩트빔의 일측단을 도어힌지와 함께 조립하여 자동차의 측면충돌시 도어에 가해진 충격을 차체로 분산시킴과 동시에 충돌시 안전성이 향상하도록 하기위한 자동차 도어 임팩트빔의 취부구조에 관한 것이다.The present invention relates to a mounting structure of an automobile door impact beam, and more particularly, an impact applied to a door during side collision of an automobile by assembling one end of an impact beam having both ends mounted on an inner panel of the automobile door together with a door hinge. The present invention relates to a mounting structure of an automobile door impact beam for dispersing the vehicle body and improving safety during a collision.

일반적으로 자동차 도어 임팩트빔(Impact Beam)은 도어의 내부에 설치되어 도어를 포함한 자동차의 측면을 보강 및 지지하는 역할을 하게된다.In general, the automobile door impact beam is installed inside the door to serve to reinforce and support the side of the vehicle including the door.

상기의 임팩트빔은 도어의 내·외측패널 사이에 설치하여 자동차의 측면 충돌시 도어에 가해진 충격을 흡수 및 완충시키고, 도어와 자동차 측면의 변형 및 파손을 최소로 함과 동시에 차실내에 탑승한 승차자를 안전하게 보호하게 된다.The impact beam is installed between the inner and outer panels of the door to absorb and cushion the impact applied to the door when the side of the car collides, minimize the deformation and damage of the door and the side of the car, and at the same time occupy the occupant in the cabin. It will protect the safety.

이러한 자동차 도어 임팩트빔의 취부구조는 도 4 및 도 5에 도시된 바와같이 전·후 양단부를 절곡하여 절곡부(11)(12)를 형성한후, 상기 절곡부(11)(12)는 도어(1)의 내측패널(2) 양단에 형성된 결합부(4)에 용착고정시켜 도어(1)에 취부시킨다.As shown in FIGS. 4 and 5, the mounting structure of the automobile door impact beam is formed by bending the front and rear ends to form the bent portions 11 and 12, and then the bent portions 11 and 12 are formed in the door. (1) is welded and fixed to the engaging portion (4) formed at both ends of the inner panel (2) to be mounted on the door (1).

이와같은 종래 자동차 도어임팩트빔의 취부구조는 도어(1)의 내·외측패널(2)(3) 사이에 전후길이 방향으로 설치되는 임팩트빔(10)에 있어서, 상기 임팩트빔(10)의 양단에 형성된 절곡부(11)(12)를 도어(1) 내측패널(2)의 양측단 결합부(4)에 용착고정시키되, 상기 임팩트빔(10)의 양측단 절곡부(11)(12) 사이는 도어(1)의 외측패널(3)에 근접설치되게 된다. 이때 상기 임팩트빔(10)과 외측패널(3) 사이에는 충격흡수용 충진재(20)가 다수곳에 개재되어 측면충돌시의 충격을 흡수하게 된다.The mounting structure of the conventional vehicle door impact beam is an impact beam 10 installed in the front-rear length direction between the inner and outer panels 2 and 3 of the door 1, both ends of the impact beam 10. Welded and fixed to bent portions 11 and 12 formed at both side coupling portions 4 of the inner panel 2 of the door 1, and bent portions 11 and 12 at both ends of the impact beam 10, respectively. The space is to be installed close to the outer panel 3 of the door (1). At this time, between the impact beam 10 and the outer panel 3, the impact absorbing filler 20 is interposed in a number of places to absorb the impact during side impact.

상기의 임팩트빔(10)은 도어(1)의 내측패널(2)에 용착고정되어 측면충돌시 충격이 가해지면 임팩트빔(10)이 충격을 흡수 및 완충시켜 도어(1)의 변형 및 파손을 줄이고, 차실내의 승차자를 보호하게 된다.When the impact beam 10 is welded and fixed to the inner panel 2 of the door 1 and an impact is applied during side impact, the impact beam 10 absorbs and cushions the impact to deform and damage the door 1. Reduce and protect passengers in the cabin.

전술한 바와같은 자동차 도어 앰팩트빔의 취부구조는 도어의 내·외측패널 사이에 설치된 임팩트빔이 도어의 내측패널에만 지지 및 고정되어 있고 차체에는 지지되는 부분이 전혀없어 측면 충돌시 충격량이 차체로 분산되지 못하고 도어부분에 한정되므로 국부적인 변형 및 파손이 심하게 발생하게 된다. 그러므로 도어의 변형 및 파손이 국부적으로 심하게 발생하고 이에따라 차실내에 탑승한 승차자 특히 도어에 근접할 위치에 탑승한 승차자가 위험한 상황에 처하게 되는 등의 문제점이 있다.As described above, the impact structure of the impact beam installed between the inner and outer panels of the door is supported and fixed only on the inner panel of the door, and there is no supported portion on the body. Since it is not distributed and is limited to the door part, local deformation and damage are severely generated. Therefore, deformation and breakage of the door occurs locally, and accordingly, there is a problem in that the occupant in the cabin, in particular, the occupant in the position close to the door is in a dangerous situation.

따라서 본 발명의 목적은 자동차 도어의 내·외측패널 사이에 설치되는 임팩트빔의 일측단을 도어 힌지부와 함께 조립하여 임팩트빔에 가해진 충격을 차체로 분산시켜 측면충돌시 도어의 국부적인 변형 및 파손을 최소로 줄일 수 있도록 한 자동차 도어의 임팩트빔 취부구조를 제공하는데 있다.Accordingly, an object of the present invention is to assemble one side end of the impact beam installed between the inner and outer panels of the automobile door together with the door hinge to distribute the impact applied to the impact beam to the vehicle body so that the local deformation and damage of the door during side impact. To provide an impact beam mounting structure of a car door to minimize the number of steps.

상기 임팩트빔(10)의 양측단 절곡부(11)(12) 사이와 도어(1)의 외측패널(3) 사이에는 충격흡수용 충진재(20)를 다수곳에 개재시킨다.The impact absorbing filler 20 is interposed between the bent portions 11 and 12 at both ends of the impact beam 10 and the outer panel 3 of the door 1 in a plurality of places.

상기와 같은 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above are as follows.

임팩트빔(10)의 일측단 절곡부(11)는 도어(1)의 측면에 부착하되 상기 절곡부(11)는 도어(1) 힌지브라켓(5)과 함께 볼트(14)로 조립하여 취부시키도록 한다.One end bent part 11 of the impact beam 10 is attached to the side of the door 1, but the bent part 11 is assembled by bolt 14 together with the hinge bracket 5 of the door 1 to be mounted. To do that.

상기 임팩트빔(10)의 타측단 절곡부(12)는 도어(1)의 내측패널(2) 일측단에 형성된 결합부(4)에 용착고정시키고, 상기 양측단 절곡부(11)(12) 사이에는 충격흡수용 충진재(20)를 다수곳에 개재시켜 도어 측면으로 충격이 가해지면 충격을 흡수하도록 한다.The other end bent part 12 of the impact beam 10 is welded and fixed to the coupling part 4 formed at one end of the inner panel 2 of the door 1, and the both end bent parts 11 and 12. Between the shock absorbing filler 20 is interposed in a number of places to absorb the impact when the impact is applied to the door side.

이와같은 본 발명의 임팩트빔으로 충격이 가해지면 임팩트빔(10)의 일측단이 차체에 결합된 도어(1) 힌지브라켓(5)과 함께 조립되어 있으므로 충격이 힌지브라켓(5)에 연결된 필라부를 통해 차체로 분산되며 도어(1)의 국부적인 변형 및 파손을 최소로 줄이게 된다.When the impact is applied to the impact beam of the present invention as described above, one side end of the impact beam 10 is assembled with the hinge bracket 5 of the door 1 coupled to the vehicle body, so that the impact is connected to the hinge bracket 5. It is distributed to the body through and minimizes local deformation and breakage of the door 1.

또한 상기 임팩트빔(10)의 양측 절곡부(11)(12) 사이에는 비트(15)를 형성하여 임팩트빔(10) 자체의 내구성 및 강성을 강화하도록 한다.In addition, the bit 15 is formed between the bent portions 11 and 12 of the impact beam 10 to enhance the durability and rigidity of the impact beam 10 itself.

상기와 같은 본 발명의 자동차 도어 임팩트빔의 취부구조는 도어의 내·외측 패널 사이에 설치되는 임팩트빔의 일측단을 도어 힌지부와 함께 조립하여 취부시킴에 따라, 차량의 측면 충돌시 도어에 가해진 충격이 필라부를 통해 차체로 분산되어 도어의 국부적인 변형 및 파손을 최소로 줄일 수 있게 된다.As described above, the mounting structure of the automobile door impact beam of the present invention is applied to the door during side collision of the vehicle by assembling and mounting one end of the impact beam installed between the inner and outer panels of the door together with the door hinge. The impact is distributed to the vehicle body through the pillars to minimize local deformation and breakage of the door.

이에따라 도어의 내·외측패널 사이에 설치된 임팩트빔이 도어에 견고하게 취부되어 차량의 측면충돌시에도 쉽게 변형 및 파손되지 않게 되고, 이에따라 차실내의 승차자가 안전한 상태를 유지할 수 있는 효과가 있다.Accordingly, the impact beam installed between the inner and outer panels of the door is firmly mounted on the door, so that the impact beam is not easily deformed or damaged even when the vehicle collides with the side of the door. Accordingly, the occupant in the vehicle can maintain a safe state.
