Description

차량의 측면 충격 흡수용 완충 장치{A shock absorber for absorbing side impact of automobile}A shock absorber for absorbing side impact of automobile

본 발명은 완충 장치에 관한 것으로, 상세하게는 차량의 측면 충돌시 임팩트 바를 고정하는 브라켓의 변형을 방지하는 차량의 측면 충격 흡수용 완충 장치에 관한 것이다.The present invention relates to a shock absorber, and more particularly, to a shock absorber for side impact absorbing of a vehicle that prevents deformation of a bracket for fixing an impact bar during side impact of the vehicle.

일반적으로, 자동차용 도어는 측면 충돌시 충격에 의해 도어가 급격하게 객실로 밀려드는 것을 방지하기 위하여, 도어의 내측 패널과 외측 패널 사이에 임팩트 바가 제공되어 측면 충돌에 따른 측면 충격력을 흡수하여 탑승객을 보호한다.In general, an automobile door is provided with an impact bar between an inner panel and an outer panel of the door in order to prevent the door from being suddenly pushed into the cabin by an impact during a side collision, so as to absorb the side impact force caused by the side collision, Protect.

도 3은 임팩트 바가 제공된 차량을 도시한 것으로, 차량의 도어(1)에는 측면 충돌에 의한 충격을 흡수하도록 임팩트 바(2)가 차량의 길이 방향으로 제공된다.3 shows a vehicle provided with an impact bar, in which the impact bar 2 is provided in the longitudinal direction of the vehicle so as to absorb a shock caused by a side collision.

도 4에 도시된 바와 같이, 임팩트 바는 접착 수단(7)에 의하여 외측 패널에 고정되고, 고정 브라켓에 의하여 내측 패널에 고정된다. 또한, 임팩트 바(2)는 길이 방향의 양단부가 고정 브라켓(3)에 의하여 내측 패널(5)의 외측면에 고정된다.As shown in FIG. 4, the impact bar is fixed to the outer panel by an adhesive means 7 and to the inner panel by a fixing bracket. In addition, both ends of the impact bar 2 are fixed to the outer surface of the inner panel 5 by the fixing bracket 3.

그러나, 상기된 바와 같은 임팩트 바의 취부 구조는 강한 충격력이 가해질 경우, 고정 브라켓이 변형되어 임팩트 바가 고정 브라켓에서 이탈되므로, 임팩트 바의 충격 흡수 능력이 저하되는 단점이 있었다.However, as described above, when a strong impact force is applied to the mounting structure of the impact bar, since the fixing bracket is deformed and the impact bar is separated from the fixing bracket, there is a disadvantage in that the impact absorbing ability of the impact bar is lowered.

따라서, 본 발명은 임팩트 바가 고정 브라켓에서 이탈되지 않도록 임팩트 바와 외측 패널 사이에 완충 장치를 제공하여 고정 브라켓에 전달되는 충격력을 감소시켜 효과적으로 측면 충격력을 흡수하는데 목적이 있다.Accordingly, an object of the present invention is to provide a shock absorbing device between the impact bar and the outer panel so that the impact bar does not escape from the fixing bracket, thereby reducing the impact force transmitted to the fixing bracket to effectively absorb the side impact force.

본 발명에 있어서의 완충 장치는, 하나의 판으로 제공되며 차량의 외측 패널의 내측면에 고정된 보강판과, 수 개의 관통공이 제공된 임팩트 바와, 일단부가 보강판에 접촉되도록 임팩트 바의 관통공에 설치되는 가이드 로드와, 임팩트 바와 보강판을 가압하도록 보강판과 임팩트 바 사이에서 가이드 로드에 설치되는 코일 스프링으로 구성된다.The shock absorber according to the present invention is provided with a reinforcing plate provided as one plate and fixed to an inner side surface of an outer panel of the vehicle, an impact bar provided with several through holes, and a through hole of the impact bar so that one end thereof contacts the reinforcing plate. The guide rod is installed, and the coil spring is installed on the guide rod between the reinforcement plate and the impact bar to press the impact bar and the reinforcement plate.

이하, 도면을 참조하여 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 차량의 측면 충격 흡수용 완충 장치의 구성이 도시되어 있다.1 shows a configuration of a shock absorber for side impact absorbing of a vehicle according to the present invention.

임팩트 바(10)의 양단은 고정 브라켓(3)에 의하여 내측 패널(5)에 고정되며, 도시되지 않은 관통공이 임팩트 바(10)의 길이 방향으로 수 개가 제공된다. 또한, 보강판(13)은 접착 수단(7)에 의하여 외측 패널(6)에 부착되며, 보강판(13)의 일측면에는 가이드 로드(11)가 고정된다.Both ends of the impact bar 10 are fixed to the inner panel 5 by fixing brackets 3, and several through holes, not shown, are provided in the longitudinal direction of the impact bar 10. In addition, the reinforcing plate 13 is attached to the outer panel 6 by an adhesive means 7, and the guide rod 11 is fixed to one side of the reinforcing plate 13.

도 2에 도시된 바와 같이, 임팩트 바(10)는 충격이 가해질 경우 변형되면서 충격력을 흡수하도록 관 형상으로 제공된다. 관통공(10a)은 임팩트 바(10)를 관통하여 형성되고 가이드 로드(11)가 삽입되어 안내된다. 코일 스프링(12)이 가이드 로드(11)에서 이탈되지 않도록 가이드 로드(11)의 하나의 단부는 보강판(13)에 고정되고, 임팩트 바(10)와 보강판(13)을 가압하도록 보강판(13)과 임팩트 바(10) 사이에서 가이드 로드(11)에 설치된다.As shown in FIG. 2, the impact bar 10 is provided in a tubular shape to absorb the impact force while deforming when the impact is applied. The through hole 10a is formed through the impact bar 10 and the guide rod 11 is inserted and guided. One end of the guide rod 11 is fixed to the reinforcement plate 13 so that the coil spring 12 is not detached from the guide rod 11, and the reinforcement plate to press the impact bar 10 and the reinforcement plate 13. The guide rod 11 is installed between the 13 and the impact bar 10.

각각의 관통공(10a)에 삽입되어 안내되는 가이드 로드(11)에 충격량이 고루 분포하여 전달되도록 보강판(13)은 하나의 판으로 형성되며 외측 패널(6)에 접착 수단(7)에 의하여 부착된다. 접착 수단(7)은 보강판(13)을 외측 패널(6)에 고정하도록 사용되므로, 용접, 리벳 이음 또는 체결구는 상기 접착수단의 요지에 벗어나지 않는 것은 당연하다.The reinforcement plate 13 is formed as one plate so that the impact amount is evenly distributed to the guide rods 11 inserted and guided into the respective through holes 10a, and the outer panel 6 is attached to the outer panel 6 by the adhesive means 7. Attached. Since the bonding means 7 are used to fix the reinforcing plate 13 to the outer panel 6, it is natural that welding, rivet joints or fasteners do not depart from the gist of the bonding means.

또한, 외측 패널(6)로부터 전달되는 충격량이 코일 스프링(12)에 분산되어 전달되도록 각각의 가이드 로드(11)는 하나의 판으로 제공된 보강판(13)에 고정된다.In addition, each guide rod 11 is fixed to the reinforcing plate 13 provided as one plate so that the impact amount transmitted from the outer panel 6 is distributed and transmitted to the coil spring 12.

상기 구성에 의하여, 보강판(13)에 고정된 가이드 로드(11)는 코일 스프링(12)가 삽입되고 임팩트 바(10)에 형성된 관통공(10a)에 안내된다. 또한, 관통공(10a)에 의하여 안내되는 가이드 로드(11)의 일단부는 관통공(10a)에서 이탈되지 않도록 너트(11a)에 체결된다. 외측 패널(6)로부터 충격량이 보강판(13)에 전달되면, 너트(11a)에 체결된 가이드 로드(11)는 관통공(10a)에 의하여 내측 패널(5)측으로 안내되어 각각의 가이드 로드(11)에 제공된 코일 스프링(12)을 압축하고, 너트(11a)에 체결된 가이드 로드(11)의 일단부는 임팩트 바(10)에서 돌출한다.By the above configuration, the guide rod 11 fixed to the reinforcing plate 13 is guided to the through hole 10a in which the coil spring 12 is inserted and formed in the impact bar 10. In addition, one end of the guide rod 11 guided by the through hole 10a is fastened to the nut 11a so as not to be separated from the through hole 10a. When the impact amount is transmitted from the outer panel 6 to the reinforcing plate 13, the guide rod 11 fastened to the nut 11a is guided to the inner panel 5 side by the through hole 10a, so that each guide rod ( The coil spring 12 provided in 11 is compressed and one end of the guide rod 11 fastened to the nut 11a protrudes from the impact bar 10.

따라서, 상기된 바와 같은 본 발명에 의하면, 임팩트 바는 코일 스프링과 가이드 로드로 구성된 완충 장치에 의하여 충격력이 흡수되어 임팩트바를 내측 패널에 고정하는 고정 브라켓에 전달되는 충격력이 감소되므로, 고정 브라켓으로부터 임팩트 바가 이탈되지 않아 효과적으로 충격력을 감소시키며 탑승객을 안전하게 보호하는 효과가 있다.Therefore, according to the present invention as described above, the impact bar is absorbed by the shock absorber consisting of the coil spring and the guide rod is reduced the impact force transmitted to the fixing bracket for fixing the impact bar to the inner panel, the impact from the fixing bracket The bar does not break off, effectively reducing the impact force and protecting the passengers.
