본 발명은 자동차용 도어의 임팩트빔에 관한 것으로서, 특히 자동차의 전면, 후면 및 측면충돌시 충격을 흡수하여 침입량을 최소화할 수 있는 자동차용 도어의 임팩트빔에 관한 것이다.The present invention relates to an impact beam of an automobile door, and more particularly, to an impact beam of an automobile door capable of minimizing the amount of invasion by absorbing a shock during a front, rear and side collision of an automobile.

통상적으로 자동차는 외부로부터의 충격을 흡수완화하기 위하여 도어의 외측패널과 내측패널 사이에 보강패널을 구비하고 있는데, 상기 보강패널 양측에 고정된 사이드임팩트빔은 자동차의 전면, 후면 및 측면으로 가해지는 출격으로부터 자동차의 실내에 앉아있는 승객의 안전을 보호하게 된다.In general, the vehicle is provided with a reinforcement panel between the outer panel and the inner panel of the door in order to absorb the shock from the outside, the side impact beam fixed to both sides of the reinforcement panel is applied to the front, rear and side of the vehicle It protects the safety of passengers sitting inside the car from sortie.

이러한, 사이드임팩트빔은 자동차의 도어내부에 고정되어 있는 것으로서, 인명피해를 최소화함과 동시에 자동차의 손상을 방지하기 위해 자동차에는 필수적으로 구비되고 있는 것이다.The side impact beam is fixed inside the door of the vehicle, and is essentially provided in the vehicle in order to minimize damage to the human life and prevent damage to the vehicle.

이와 같이 자동차의 도어내측에 구비된 보강패널에 고정된 사이드임팩트빔의 일례를 살펴보면 제1도에 도시된 바와같이 자동차의 도어(1)의 내측에 구비된 보강패널(14)의 중심에는 사이드임팩트빔(10)이 길이방향으로 양측이 상기 보강패널(14)에 고정된다.An example of the side impact beam fixed to the reinforcement panel provided inside the door of the vehicle, as shown in FIG. 1, is the side impact at the center of the reinforcement panel 14 provided inside the door 1 of the vehicle. Both sides of the beam 10 in the longitudinal direction are fixed to the reinforcement panel 14.

따라서, 상기 도어(1)의 외측에 구비된 외측패널(12)에 충격이 가해지면, 이 충격은 상기 보강패널(14)에 설치된 사이드임팩트빔(10)에서 일차적으로 충격을 흡수완충시키고, 상기 사이드임팩트빔(10)을 통과한 충격량은 도어(1)의 내측패널(16)에 전달되어 지면서 외부로부터의 충격량을 점차적으로 감소시키는 구조를 갖고 있었다.Therefore, when an impact is applied to the outer panel 12 provided on the outside of the door 1, the impact primarily absorbs and buffers the impact in the side impact beam 10 installed in the reinforcing panel 14, The impact amount passing through the side impact beam 10 was transmitted to the inner panel 16 of the door 1 and gradually reduced the impact amount from the outside.

그러나, 이와 같은 구조를 갖는 도어(1)의 내부에 구비된 사이드임팩트빔(10)의 양측을 보강패널(14)에 고정시킴에 있어서, 단순히 상기 사이드임팩트빔(10) 한 개만을 사용할 경우 강성이 양호한 형태로의 구조를 갖을 수 없기 때문에 외부로부터의 충격시 침입((Intrusion)량이 크게되어 자동차의 도어(1)가 손상되는 문제점을 갖고 있었다.However, in fixing both sides of the side impact beam 10 provided in the interior of the door 1 having such a structure to the reinforcement panel 14, the rigidity when only one side impact beam 10 is used Since it was impossible to have a structure in this preferred form, the amount of intrusion during the impact from the outside was large and the door 1 of the automobile was damaged.

특히, 자동차용 도어(1)의 내부에 설치된 사이드임팩트빔(10)은 자동차의 고속주행시에 측면부가 충돌되었을 경우 일차충격량을 흡수완화시켜 자동차를 보호할 수 있는 기능을 수행하여야 하는데, 상기와 같이 사이드임팩트빔(10)이 한 개밖에 없으므로 구조적으로 강성을 제공하기가 어려움은 물론 외부의 측면충격에 대한 흡수효율이 떨어지게 된다.In particular, the side impact beam 10 installed inside the vehicle door 1 should perform a function of protecting the vehicle by absorbing and reducing the primary impact amount when the side portion collides during the high speed driving of the vehicle. Since there is only one side impact beam 10, it is difficult to provide structural rigidity, and the absorption efficiency against external side impacts is reduced.

아울러, 상기 사이드임팩트빔(10) 하나만으로는 외부충격량에 대해서 많은 변형을 이루기 때문에 측면으로부터의 침입량이 많아지게 되어 결국은 승객의 안전을 보호하기가 어려울 뿐만 아니라 인명피해를 많이 입게되는 문제점을 갖고 있었다.In addition, since only one side impact beam 10 makes a lot of deformation with respect to the external impact amount, the amount of intrusion from the side is increased, and thus, it is difficult to protect the safety of the passengers and suffer a lot of human injury. .

이에 본 발명은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 외부로부터의 측면충돌시에 충격분포를 고르게하여 자동차내측으로 침입량을 최소화함으로써, 자동차의 도어측부위를 보호함과 동시에 인명피해를 최소화할 수 있는 자동차용 도어의 임팩트빔를 제공함에 있다.Accordingly, the present invention has been made in view of the above problems, the object of which is to minimize the intrusion into the inside of the car by evenly impact distribution during side impact from the outside, to protect the door side of the car and at the same time The present invention provides an impact beam of a door for an automobile that can minimize damage.

이러한 본 발명의 목적은 자동차의 측면부에 구비된 보강패널 양측에 고정되어 외부의 충격을 흡수완화시키는 사이드임팩트빔이 설치된 도어에 있어서, 상기 사이드임팩트빔의 상.하부에 길이방향으로 설치되며, 양측이 각각 상기 보강패널에 고정되는 상부사이드임팩트빔 및 하부사이드임팩트빔과, 상기 사이드임팩트빔과 상부사이드임팩트빔 및 하부사이드임팩트빔 사이에 수직방향으로 설치되며, 양측이 각각 상부사이드임팩트빔 및 하부사이드임팩트빔 사이에 등간격으로 고정되는 수개의 리브빔을 구비하여 달성될 수 있다.The object of the present invention is fixed to both sides of the reinforcement panel provided on the side of the vehicle is installed in the side impact beam for absorbing the external shock, the side impact beam is installed in the longitudinal direction at the upper and lower sides of the side impact beam, both sides The upper side impact beam and the lower side impact beam fixed to the reinforcement panel, respectively, and are installed in the vertical direction between the side impact beam, the upper side impact beam and the lower side impact beam, both sides of the upper side impact beam and lower It can be achieved by having several rib beams fixed at equal intervals between the side impact beams.

이하 본 발명의 바람직한 실시예를 첨부 도면에 의거하여 좀 더 구체적으로 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

제2도 및 제3도에는 본 발명의 구성이 도시되어 있는데, 이에 따르면 본 발명은 자동차용 도어(1)의 외측패널(12)과 내측패널(16) 사이에는 보강패널(14)이 구비되고, 상기 보강패널(14) 양측에 고정되어 외부의 충격을 흡수완화시키는 사이드임팩트빔(10)이 설치된다.2 and 3 show a configuration of the present invention, which according to the present invention is provided with a reinforcement panel 14 between the outer panel 12 and the inner panel 16 of the door 1 for the vehicle. The side impact beam 10 is fixed to both sides of the reinforcement panel 14 to absorb and absorb external shocks.

상기 사이드임팩트빔(10)의 상부 및 하부에는 길이방향으로 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30)의 양측이 상기 보강패널(14)에 고정되도록 설치한다.Both sides of the upper side impact beam 20 and the lower side impact beam 30 are installed to the reinforcement panel 14 at upper and lower portions of the side impact beam 10 in the longitudinal direction.

그리고, 상기 사이드임팩트빔(10)과 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30) 사이에는 등간격으로 수개의 리브빔(40)이 고정된다. 즉, 상기 리브빔(40)의 양측은 상기 사이드임팩트빔(10)과 상부사이드임팩트빔(20) 사이에 고정되는 것이며, 또한 상기 사이드임팩트빔(10)과 하부사이드임팩트빔(30) 사이에도 등간격을 이루는 수개의 리브빔(40)의 양측이 고정설치되는 구성을 갖는 것이다.Further, several rib beams 40 are fixed at equal intervals between the side impact beam 10, the upper side impact beam 20, and the lower side impact beam 30. That is, both sides of the rib beam 40 are fixed between the side impact beam 10 and the upper side impact beam 20, and also between the side impact beam 10 and the lower side impact beam 30. Both sides of the several rib beams 40 having equal intervals are fixedly installed.

이와 같은 구성을 갖는 본 발명은 자동차용 도어(1)의 측면에 구비된 외측패널(12)상에 외부로부터의 측면충돌이 가해지게되면, 이 충격은 상기 외측패널(12)에서 일차적으로 흡수수용됨과 동시에 보강패널(14)상에 고정된 사이드임팩트빔(10), 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30)으로 전달된다.According to the present invention having such a configuration, when a side collision from the outside is applied to the outer panel 12 provided on the side of the automobile door 1, the impact is primarily absorbed by the outer panel 12. At the same time it is delivered to the side impact beam 10, the upper side impact beam 20 and the lower side impact beam 30 fixed on the reinforcement panel (14).

따라서, 상기 사이드임팩트빔(10), 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30)은 길이방향으로 이루어져 있으므로 상기 외부로부터의 전면,후면 및 측면의 충격을 흡수함과 동시에 상기 사이드임팩트빔(10), 상부 사이드임팩트빔(20) 및 하부사이드임팩트빔(30)의 양측으로 충격이 분산 전달된다.Therefore, since the side impact beam 10, the upper side impact beam 20 and the lower side impact beam 30 are formed in the longitudinal direction, the side impact absorbs impacts of the front, rear and side surfaces from the outside. The impact is distributed and transmitted to both sides of the beam 10, the upper side impact beam 20, and the lower side impact beam 30.

그리고, 상기 사이드임팩트빔(10), 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30)의 양측으로 분산전달되어진 충격량은 상기 사이드임팩트빔(10)과 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30) 사이에 수직방향으로 설치되며, 양측이 각각 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30) 사이에 등간격으로 고정되는 수개의 리브빔(40)은 특히 상기 외부로부터의 측면충격량을 흡수완화시켜 주기 때문에 상기 도어(1)의 내측패널(16)에서 상기 측면충격량을 최종적으로 흡수완화하기 때문에 자동차의 측면에 구비된 도어(1)의 안측으로 상기 충격량이 밀려들어가는 것을 저지할 수 있게 된다.The impact amounts distributed to both sides of the side impact beam 10, the upper side impact beam 20, and the lower side impact beam 30 are the side impact beam 10, the upper side impact beam 20, and the lower side impact beam. Several rib beams 40 are installed in the vertical direction between the side impact beams 30 and fixed at equal intervals between the upper side impact beams 20 and the lower side impact beams 30, respectively. Since the side impact amount from the side is absorbed and relaxed, the inner side panel 16 of the door 1 finally absorbs the side impact amount so that the impact amount is pushed into the inner side of the door 1 provided on the side of the vehicle. You can stop it.

그러므로, 자동차의 실내에 앉아 있는 승객은 외부로부터의 측면충격을 받게되더라도 이 충격에 대한 충격량을 상기 사이드임팩트빔(10)과 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30) 사이에 수직방향으로 설치되며, 양측이 각각 상부사이드임팩트빔(20) 및 하부사이드임팩트빔(30) 사이에 등간격으로 고정되는 수개의 리브빔(40)이 고르게 분산시켜 주기 때문에 도어(1) 내측으로 침입량을 최소화함으로써, 차체를 보호함과 동시에 인명피해를 최소화할 수 있게 되는 것이다.Therefore, the passenger sitting in the interior of the vehicle is perpendicular to the impact amount of the impact between the side impact beam 10 and the upper side impact beam 20 and the lower side impact beam 30 even if the passenger is subjected to a side impact from the outside. Installed in the direction, and both sides of the rib beams 40 fixed at equal intervals between the upper side impact beam 20 and the lower side impact beam 30 are evenly distributed so that they penetrate into the door 1. By minimizing the amount, it is possible to protect the body and minimize the damage to the human body.
