Description

사이드 임팩트 장치Side impact device

본 발명은 차량용 도어의 사이드 임팩트 장치에 관한 것으로, 특히 임팩트빔의 강성을 증대할 수 있도록 하여 측면충돌시에 임팩트빔의 파손 및 휨을 감소시키고, 승객의 안전을 도모할 수 있도록 한 사이드 임팩트 장치에 관한 것이다.The present invention relates to a side impact device of a door for a vehicle, and more particularly, to a side impact device that can increase the rigidity of the impact beam, thereby reducing damage and warpage of the impact beam during side impact, and promoting passenger safety. It is about.

일반적으로 종래의 차량에는 차량의 측면충돌시 측면으로부터 가해지는 충격력이 실내로 전달되어 탑승자에게 부상을 입히는 것을 방지하고 안전을 도모할 수 있도록 도어의 내측 공간부에 임팩트바를 설치하였다. 이와 같은 종래의 임팩트바가 설치된 상태가 도 1 에 도시되어 있다.In general, in the conventional vehicle, an impact bar is installed in the inner space of the door so that impact force applied from the side when the vehicle collides with the vehicle is transferred to the interior to prevent injury to the occupant and promote safety. A state where such a conventional impact bar is installed is shown in FIG. 1.

도 1 에 도시된 바와 같이, 종래의 임팩트바(1)는 내측에 중공(2)을 형성한 단일체의 파이프(3)를 도어 외측 패널(4)의 내측면에 설치하되, 접착씰러(5)를 부착하여 상기 접착씰러(5)의 접착력에 의해 고정될 수 있도록 하였다.As shown in FIG. 1, the conventional impact bar 1 is provided with a single pipe 3 having a hollow 2 formed therein on the inner side of the door outer panel 4, but with an adhesive sealer 5. Was attached to be fixed by the adhesive force of the adhesive sealer (5).

상기와 같이 설치된 임팩트바의 작용을 살펴보면 다음과 같다.Looking at the action of the impact bar installed as above.

차량의 측면으로부터 충격력이 가해지면 1차적으로 도어 외측 패널(4)이 충격력을 흡수하면서 내측으로 찌그러지게되고, 상기 도어 외측 패널(4)로부터 충격력을 전달받은 임팩트바(1)가 2차 충격력을 흡수하면서 휘어지는 것이다.When the impact force is applied from the side of the vehicle, the door outer panel 4 is crushed inward while absorbing the impact force, and the impact bar 1 receiving the impact force from the door outer panel 4 receives the secondary impact force. It is bent while absorbing.

따라서, 상기 도어 외측 패널(4)과 임팩트바(1)가 단계적으로 충격력을 흡수하여 실내에 탑승한 승객에게는 최소한의 충격력만을 전달하여 승객의 부상을 방지할 수 있도록 하는 것이다.Therefore, the door outer panel 4 and the impact bar 1 absorbs the impact force step by step to transmit only the minimum impact force to the passengers in the room to prevent the injury of the passengers.

그러나, 상기한 종래의 임팩트바(1)는 내측에 중공(2)을 형성한 단일체의 파이프(3)이므로 강성이 약하여 충격력이 가해졌을 때 내측으로 절곡되는 양이 클 경우 오히려 절곡되는 부분이 내측으로 돌출되면서 승객의 측면에 충격력을 가하여 부상을 입히게되는 문제가 있었다.However, since the conventional impact bar 1 is a single-piece pipe 3 having a hollow 2 formed therein, the rigid portion is weak, so when the amount of bending is large when the impact force is applied, the portion to be bent is rather inner. There was a problem that the injury caused by applying a shock force to the side of the passenger while protruding to.

따라서, 본 발명은 상기한 종래의 문제점을 해결하기 위하여 창안한 것으로, 측면충돌시 2중으로 충격력을 흡수할 수 있도록 임팩트빔의 내측에 임팩트바를 설치하여 임팩트빔이 절곡되는 것을 최소화하고, 절곡부가 실내로 침투하는 것을 방지하여 승객의 부상을 방지하는 데 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned problems, and minimizes the bending of the impact beam by installing an impact bar inside the impact beam so as to absorb the impact force in a double side collision. Its purpose is to prevent injuries to passengers by preventing them from infiltrating into.

이하 첨부된 도면에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2 내지 도 3 에서 나타낸 바와 같이, 본 발명은 도어 외측패널(10)의 내측면에 설치되는 임팩트빔(20)과, 상기 임팩트빔(20)의 내부면에 결합 설치되고 양측면에 다수개의 통공(31)을 형성한 임팩트바(30)와, 상기 임팩트빔(20)과 임팩트바(30)을 결합하는 결합수단(40)과, 상기 임팩트빔(20)을 도어 외측 패널(10)에 고정시키는 접착씰러(50)로 구성한다.As shown in Figures 2 to 3, the present invention is coupled to the impact beam 20 is installed on the inner surface of the door outer panel 10, the inner surface of the impact beam 20 and a plurality of through holes on both sides An impact bar 30 having a 31 formed therein, a coupling means 40 for coupling the impact beam 20 and the impact bar 30, and the impact beam 20 are fixed to the door outer panel 10. It consists of an adhesive sealer (50).

상기 임팩트빔(20)은 내측에 상기 임팩트바(30)가 삽입될 수 있는 중공(21)부를 형성하고, 상·하부면에 측면의 강성을 증대하기 위한 비드(BEAD)(22)를 형성한다.The impact beam 20 forms a hollow 21 portion into which the impact bar 30 can be inserted, and a bead 22 for increasing stiffness of side surfaces on the upper and lower surfaces thereof. .

또한 상기 임팩트빔(20)은 상기 임팩트바(30)의 통공(31)과 대응되는 다수개의 통공(23)을 양측면에 형성한다.In addition, the impact beam 20 forms a plurality of through holes 23 corresponding to the through holes 31 of the impact bar 30 on both sides.

상기 임팩트빔(20)과 임팩트바(30)의 결합은 상기 임팩트바(30)를 임팩트빔(20)의 중공(21)에 삽입하되, 각각의 측면에 형성된 통공(23, 31)이 일치하도록 한다.Combination of the impact beam 20 and the impact bar 30 inserts the impact bar 30 into the hollow 21 of the impact beam 20, so that the through holes (23, 31) formed on each side coincide do.

상기와 같이 임팩트바(30)를 임팩트빔(20)에 삽입한 후에는 상기 통공(23, 31)을 관통하여 체결되는 보울트(41)와 너트(42)같은, 체결수단(40)을 이용하여 일체로 결합한다.After inserting the impact bar 30 into the impact beam 20 as described above, by using the fastening means 40, such as the bolt 41 and the nut 42 fastened through the through holes 23 and 31. Unite integrally.

상기와 같이 결합된 임팩트빔(20)의 일측면에 접착 씰러(50)를 부착하여 도어 외측패널(10)의 내측면에 부착하여 고정 설치한다.The adhesive sealer 50 is attached to one side of the impact beam 20 coupled as described above and fixedly attached to the inner side of the door outer panel 10.

상기와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

차량의 측면으로부터 충격결이 가해지면 도어 외측 패널(10)이 1차적으로 충격력을 흡수하게 되고, 내측에 설치된 임팩트빔(20)에 충격력을 전달하게된다.When an impact grain is applied from the side of the vehicle, the door outer panel 10 primarily absorbs the impact force, and transmits the impact force to the impact beam 20 installed inside.

상기와 같이 충격력이 임팩트빔(20)에 전달되면 임팩트빔(20)의 측면과, 임팩트빔(20)의 내부에 설치된 임팩트바(30)가 충격력을 흡수하면서 임팩트빔(20)의 상·하부면에 형성된 비드(22)를 통해 충격력이 분산흡수되도록 한다.As described above, when the impact force is transmitted to the impact beam 20, the side of the impact beam 20 and the impact bar 30 installed inside the impact beam 20 absorb the impact force, and the upper and lower portions of the impact beam 20. Through the bead 22 formed on the surface to be absorbed by the impact force.

또한 이때 상기 임팩트빔(20)과 임팩트바(30)를 결합하고있는 체결수단(40)도 수평으로 설치되어 있으므로 측면충격력을 버틸 수 있는 것이다.In addition, since the fastening means 40 coupling the impact beam 20 and the impact bar 30 is also installed horizontally, the side impact force can be sustained.

따라서, 상기 임팩트빔(20)은 충격력을 흡수할 뿐아니라 분산시킬 수 있도록 하여 충격력에 의해 절곡되는 절곡양을 최소화하고 실내의 침투를 최소화 할 수 있도록 함으로써, 승객의 부상을 방지할 수 있도록 하는 것이다.Therefore, the impact beam 20 is to be able to not only absorb the impact force, but also to disperse, to minimize the amount of bending bent by the impact force and to minimize the penetration of the room, thereby preventing the injury of passengers. .

이상에서 살펴본 바와 같이, 본 발명은 측면충돌시 2중으로 충격력을 흡수할 수 있도록 임팩트빔의 내측에 임팩트바를 설치하여 임팩트빔이 절곡되는 것을 최소화하고, 절곡부가 실내로 침투하는 것을 방지하여 승객의 부상을 방지할 수 있도록 한 것이다.As described above, the present invention minimizes the impact beam bending by installing an impact bar inside the impact beam so as to absorb the impact force in the event of a side collision, and prevents the bent portion from penetrating into the interior of the passenger It is to prevent this.
