본 발명은 자동차 도어의 충격흡수용 임팩트바에 관한 것으로, 특히 외부패널과 내부패널 사이에 형성되는 임팩트바의 끝단에 여러번 반복되게 구부러진 제2보강재를 용접수단에 의하여 일체로 형성한 자동차 도어의 충격흡수용 임팩트바에 관한 것이다.The present invention relates to a shock absorbing impact bar of a car door, and more particularly, to absorbing shocks of a car door integrally formed by welding means with a second reinforcing material bent repeatedly at the end of an impact bar formed between an outer panel and an inner panel. For impact bars.
일반적으로, 도어에 설치되는 임팩트바는 제1도에 나타낸 바와 같이, 측면 충돌시에는 프론트도어와 리어도어를 형성하는 각 패널에 별도의 충격 흡수장치가 없기때문에, 측면 충돌에 의한 충격을 흡수하지 못하여 차체(필러부)의 변형을 심하게 가져 왔었다.In general, the impact bars installed on the doors do not absorb impacts caused by side impacts, as shown in FIG. 1, since there is no separate shock absorber on each panel forming the front door and the rear door during side impacts. It could not bring the deformation of the car body (pillar part) badly.
또한, 탑승자에 가해지는 충격력이 강하여 쇽과 같은 상태에 의하여 증상 또는 사망하는 일을 야기시킬 수가 있었다.In addition, the impact force applied to the occupant was so strong that it could cause symptoms or death due to shocks.
따라서, 본 발명의 목적은, 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 외부패널과 내부패널 사이에 형성되는 임팩트바의 끝단에 평탄면을 가지는 제1보강재와 여러번 반복되게 구부러진 제2보강재를 용접수단에 의하여 일체로 형성하여 측면 충돌시 제1보강재가 충격을 분산시킴과 동시에, 제2보강재가 충격을 점차 흡수하면서 충격량을 감소시키고 이 감소된 충격량을 차체로 보내어 최종적으로 충격을 분산시킴으로서, 탑승자의 안전 및 차량의 변형(도어 및 필러(pillar))을 최대한 줄이고자 한다.Accordingly, an object of the present invention is to solve the conventional problems as described above, the first reinforcement having a flat surface at the end of the impact bar formed between the outer panel and the inner panel and the second reinforcement bent repeatedly many times. By forming integrally by welding means, the first reinforcement disperses the impact during side impact, while the second reinforcement gradually absorbs the impact and reduces the amount of impact and sends the reduced impact amount to the vehicle body to finally distribute the impact. To minimize occupant safety and vehicle deformation (doors and pillars) as much as possible.
상기와 같은 목적을 달성하기 위하여 본 발명 자동차 도어의 충격흡수용 임팩트바는, 외부패널과 내부패널로 이루어지는 도어와; 상기 외부패널과 내부패널사이에 설치되어 충돌시 그 충격을 흡수 완화하는 임팩트바와; 상기 임팩트바는 양단부에 설치되는 제1보강재 및 제2보강재가 용접수단에 의하여 고정되는 자동차 도어에 있어서, 상기 제2보강재는 여러번 반복되게 구부러진 것을 특징으로 한다.In order to achieve the above object, the impact absorbing impact bar of the automobile door of the present invention comprises: a door made of an outer panel and an inner panel; An impact bar installed between the outer panel and the inner panel to absorb and mitigate the impact upon impact; The impact bar is a vehicle door in which the first reinforcement and the second reinforcement, which are installed at both ends, are fixed by welding means, wherein the second reinforcement is repeatedly bent repeatedly.
또, 상기 제1보강재가 충격을 분산시킴과 동시에, 제2보강재가 충격을 점차 흡수하여 충격량을 감소시키고 이 감소된 충격량을 차체로 보내어 최종적으로 충격을 분산시키는 것을 특징으로 한다.In addition, the first reinforcing material to distribute the impact, and at the same time the second reinforcing material gradually absorbs the impact to reduce the amount of impact and send the reduced amount of impact to the vehicle body, it is characterized in that the final distribution of the impact.
이하 본 발명의 기술적 구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings the technical configuration and effect of the present invention.
먼저, 제4도 내지 제6도를 참조하여 설명한다.First, a description will be given with reference to FIGS. 4 to 6.
10은 외부패널(20)과 내부패널(30)로 이루어지는 도어이다.10 is a door composed of an outer panel 20 and an inner panel 30.
상기 외부패널(20)과 내부패널(30) 사이에는 임팩트바(40)가 설치되고, 상기 임팩트바(40)의 양 끝단에는 제1보강재(41) 및 제2보강재(42)가 각각 설치된다. 예를들면, 상기 제1보강재(41)는 평면형상으로 이루어짐과 동시에, 일 끝단이 임팩트바(40)의 상단 끝단부에 용접에 의하여 고정되고, 다른 쪽 끝단부는 외부패널(20)과 내부패널(30)의 절곡부(31) 사이에 설치되어 용접수단에 의하여 설치된다.An impact bar 40 is installed between the outer panel 20 and the inner panel 30, and first and second reinforcing materials 41 and 42 are respectively installed at both ends of the impact bar 40. . For example, the first reinforcing material 41 is formed in a flat shape, one end is fixed by welding to the upper end of the impact bar 40, the other end is the outer panel 20 and the inner panel It is provided between the bent parts 31 of 30, and is installed by a welding means.
상기 제1보강재(41)는 충돌시 충격력을 분산시키는 역할을 하도록 한다.The first reinforcing material 41 serves to distribute the impact force during the collision.
또, 제2보강재(42)는 대략 형상으로 이루어지며, 상기 임팩트바(40) 하부와 상기 내부패널(30)의 내측벽(32) 사이에 용접수단에 의하여 고정된다. 이어서, 상기 제2보강재(42)는 ①번 부위가 밀리면서 충격을 흡수하고, 이어서 ②번 부위가 따라 들어오면서 재차 흡수함과 동시에, 이 충격량을 ③,④번 부위로 연이어 전달하여 충격량을 흡수/완화시키는 역할을 한다(제5도 참조).In addition, the second reinforcing material 42 has a substantially shape, and is fixed by welding means between the impact bar 40 and the inner wall 32 of the inner panel 30. Subsequently, the second reinforcing material 42 absorbs the shock as the part ① is pushed, and then absorbs again as the part ② follows, and simultaneously delivers the impact amount to the part ③ and ④ to absorb the impact amount. It acts to alleviate (see Figure 5).
50은 차체를 이루는 필러(pillar)부분을 나타낸다.50 represents the pillar part which forms a vehicle body.
상기와 같이 구성되는 자동차 도어의 충격흡수용 임팩트바는, 자동차가 측면에서 충돌할 경우 제2보강재(42)가 ①, ②, ③, ④번으로 차례로 충격량을 흡수/완화하여 전달하므로써, 도어(10)에 받은 충격량을 서서히 감소시키고 이 감소된 충격량을 필러(50)로 보내어 최종적으로 충격을 분산시킴으로서, 차량의 변형(도어 및 필러(pillar))을 최대한 줄이고, 또 이러한 충격 완화수단에 의하여 운전자나 탑승자에 전달되는 충격량을 최소화할 수 있도록 한 것이다.Impact absorbing impact bar of the vehicle door is configured as described above, the second reinforcing material 42 absorbs / mitigated the impact amount in order to ①, ②, ③, ④ when the car collides from the side, the door ( 10) by gradually reducing the amount of impact received and sending the reduced amount of impact to the filler 50 to finally disperse the impact, thereby minimizing the deformation of the vehicle (door and pillar) and by the impact mitigating means. It is to minimize the amount of impact delivered to the occupant.
