본 고안은 차량의 도어 보강구조에 관한 것으로, 특히 임팩트바 대신 새로운 보강재를 설치하여 보강재의 강성을 증대시키므로 차량의 측면 충돌시 충격력을 흡수할 수 있도록 함으로써, 탑승자의 안전을 도모할 수 있도록 한 도어 보강구조에 관한 것이다.The present invention relates to a door reinforcement structure of a vehicle, and in particular, by installing a new reinforcement instead of the impact bar to increase the rigidity of the reinforcement to absorb the impact force in the side impact of the vehicle, the door to promote the safety of the occupants It relates to a reinforcement structure.

일반적으로 현재 양산중인 차량은 도어에 임팩트바를 설치하여 차량의 측면 충돌시 탑승자의 안전을 도모할 수 있도록 하는 것으로, 종래의 구조는 제1도에서 나타낸 바와 같이, 내측패널(10)과 외측패널(20) 사이에 임팩트바를 설치한 것으로, 차량의 측면 충돌시 상기 외측패널(20)이 충격을 받으면 내측으로 꺽어지고, 이에 따라 내측에 설치된 임팩트바(30)가 충격을 흡수하면서 내측으로 꺽여지며, 내측패널(10)이 최종적으로 단류하는 충격력을 흡수하여 탑승자에게 충격력이 전달되는 것을 방지하므로, 탑승자의 안전을 도모했다.In general, a vehicle currently being mass-produced to install an impact bar on the door to ensure the safety of the occupant during side impact of the vehicle, the conventional structure, as shown in Figure 1, the inner panel 10 and the outer panel ( 20) the impact bar is installed between, when the outer panel 20 is impacted during the side impact of the vehicle is bent inward, and thus the impact bar 30 installed on the inside is bent inward while absorbing the impact, Since the inner panel 10 absorbs the impact force that finally flows to prevent the impact force from being transmitted to the occupant, the safety of the occupant is promoted.

그러나, 상기한 종래의 구조는 차량의 충격시 임팩트바(30)가 충격력을 분산시킬 수 있으나, 임팩트바(30)의 형상이 일자형의 단면으로 되어 있으므로, 충격력이 전달될시 내측패널(10)쪽으로 입착되어 오히려 임팩트바(30)에 의해 내측패널(10)에 충격력이 가해지므로, 탑승자에게 부상을 입힐 수 있는 역효과의 문제가 발생되었다.However, in the conventional structure described above, the impact bar 30 may disperse the impact force during the impact of the vehicle, but since the shape of the impact bar 30 is a straight cross section, the inner panel 10 when the impact force is transmitted. Since the impact force is applied to the inner panel 10 by the impact bar 30, the side effects of the adverse effects that may cause injury to the occupants are generated.

따라서 본 고안은 상기한 종래의 문제점을 해결하기 위해 안출한 것으로, 차량의 측면 충돌시 충격을 분산흡수하면서, 내측패널부에 가해지는 충격력을 최소화 할 수 있도록 하여 내측패널이 실내로 절곡되면서 탑승자에게 부상을 입히는 것을 방지하므로, 탑승자의 안전을 도모할 수 있도록 하는데 그 목적이 있다.Therefore, the present invention has been devised to solve the above-mentioned problems, while absorbing the impact during the side collision of the vehicle, while minimizing the impact force applied to the inner panel portion, the inner panel is bent indoors to the occupant In order to prevent injuries, the purpose is to ensure the safety of the occupants.

상기 목적을 달성하기 위해 본 고안은 임팩트바의 형성을 변형하여 상.하에 플랜지를 형성하고, 중앙부에 일측이 개구된 반원형의 봉을 형성하며, 봉의 내부면에 충격흡수용 고무패드을 부착하여 측면 충돌시 임팩트바가 내측으로 밀리되, 단기 반원형이 봉이 벌어지면서 내측의 충격흡수용 고무가 패드 내측패널에 부딛치도록 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention deforms the impact bar to form a flange at the top and bottom, forms a semicircular rod having one side open at the center portion, and attaches a shock absorbing rubber pad to the inner surface of the rod, thereby causing side impact. When the impact bar is pushed inward, the short-circle semicircle is characterized in that the shock-absorbing rubber on the inner side of the pad hit the inner panel as the rod opens.

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

제2도에서 나타낸 바와 같이, 내측패널(10)과 외측패널(20) 및 임팩트바(30)로 구성된 도어 보강구조에 있어서, 상기 임팩트바(30)는 상.하에 플랜지(31)(31')를 형성하고 중앙부에 일측이 개구된 반원형의 봉(32)을 형성하며, 상기 봉(32)의 내측면에 충격흡수 고무패드(33)를 부착하여 구성한다.As shown in FIG. 2, in the door reinforcement structure consisting of the inner panel 10, the outer panel 20, and the impact bar 30, the impact bar 30 is flanged 31, 31 'up and down. ) To form a semicircular rod 32 having one side open at the center, and attaching the shock absorbing rubber pad 33 to the inner surface of the rod 32.

상기와 같이 구성된 본 고안의 작용 및 효과를 보면 다음과 같다.Looking at the operation and effects of the present invention configured as described above are as follows.

차량의 측면 충돌시 외측패널(20)에 충격이 가해지면 외측패널(20)이 내측으로 밀리면서, 임팩트바(30)의 플랜지(31)(31')와 봉(32)의 외측면에 충격을 가하면, 상기 봉(32)이 충격력에 의해 상.하로 벗어지면서, 내측면에 부착된 충격 흡수용 고무패드(33)가 돌출되어, 상기 충격흡수용 고무패드(33)에 의해 충격력이 분산흡수되어 내측패널(10)이 실내로 침입하는 졸음방지하여 탑승자에게 부상을 입히는 것을 방지할 수 있는 것이다.When an impact is applied to the outer panel 20 during the side collision of the vehicle, the outer panel 20 is pushed inward, and impacts the outer surfaces of the flanges 31, 31 ′ and the rod 32 of the impact bar 30. When the rod 32 is lifted up and down by the impact force, the shock absorbing rubber pad 33 attached to the inner side protrudes, and the impact force is absorbed by the shock absorbing rubber pad 33. The inner panel 10 is to prevent drowsiness to invade the interior to prevent injury to the occupants.

이상에서 살펴본 바와 같이, 본 고안은 차량의 도어에 설치되는 임팩트바의 형상을 개선함으로서, 차량의 측면 충돌시 임팩트바의 충격 흡수용 고무패드가 내측패널과 마찰되면서 충격력을 분산시키므로 내측패널에 가해지는 충격력에 의해 내측패널이 실내로 침투하는 것을 방지하여 탑승자의 안전을 도모할 수 있는 매우 유용한 고안인 것이다.As described above, the present invention improves the shape of the impact bar installed on the door of the vehicle, so that the impact absorbing rubber pads of the impact bar disperse the impact while rubbing the inner panel during impact of the vehicle, so that the impact force is applied to the inner panel. It is a very useful design that can protect the occupant's safety by preventing the inner panel from penetrating into the room by the impact force.
