Description
본 발명은 자동차의 도어에 관한 것으로, 더 상세하게는 차량의 측면충돌(SIDE IMPACT)시 도어 하단의 충격흡수 증대와 실내밀림량 및 찌그러짐을 억제시켜, 측면충돌시 차내 승객에게 가해지는 인체상해치를 최대한 감소시키는 동시에 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 도어 하단부 보강구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door of an automobile, and more particularly, to an automobile door which is capable of suppressing an increase in impact absorption at the lower portion of the door and an indoor jamming amount and a collapse during a side impact, The present invention relates to a structure for reinforcing the lower portion of a door of an automobile,
일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌과 측면충돌이 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 큰 항목으로 이용하고 있다.In general, tests for securing the safety of passengers in the event of an automobile collision include frontal collision and side collision. This is an important factor for ensuring safety of automobiles. As a large item of.
그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌시에 대한 안전치는 어느정도 확보하고 있으나, 반면에 측면충돌에 대한 도어의 하단부 안전치는 미흡한 실정이다.However, most of the automobiles currently produced have a certain level of safety against frontal collision, while the safety of the lower side door against side collision is insufficient.
그 원인으로는 차체의 도어 하단부 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시 도어의 하단에서 충분한 충격흡수가 되지 못하여 인체상해치가 커지기 때문이다.The reason for this is that the structure of the lower portion of the door of the vehicle body is weak. In fact, when the vehicle collides with the side of the vehicle, the shock is not absorbed sufficiently at the lower end of the door.
종래의 도어 하단부 구조는 도 2 에 도시되는 바와 같이, 도어이너판넬(1)과 도어아웃터판넬(2)이 결합되어 도어(3)를 구성하는 단순한 구조로 구성된다.The conventional door lower end structure has a simple structure in which the door inner panel 1 and the door outer panel 2 are combined to constitute the door 3 as shown in Fig.
따라서, 이러한 종래의 도어 하단부 구조는 그 지지강성이 매우 취약하여 외부로 부터 차량이 측면으로 충돌해 왔을 때 도어(3)의 하단부에서 충분한 충격흡수가 되지 않고, 도어아웃터판넬(2)이 쉽게 찌그러지면서 실내로 밀려 들어오기 때문에, 도어(1)의 측하단부에서 충분한 충격흡수가 이루어지지 못하여 실내밀림량이 커지므로 차내 승객에게 전달되는 인체상해치가 커지는 문제점과 이로 인하여 자동차의 안전성을 저하되는 문제점이 있었다.Accordingly, such a conventional door lower end structure is very weak in its supporting rigidity, so that when the vehicle collides with the side from the outside, the shock absorber at the lower end of the door 3 is not sufficiently absorbed, and the door outer panel 2 easily collapses The door 1 is not sufficiently absorbed by shocks at the lower end of the door 1, so that the amount of indoor climbing becomes large, so that the level of human injury transmitted to a passenger in the passenger compartment is increased and the safety of the vehicle is lowered .
본 발명의 목적은 차량의 측면충돌시 도어 하단의 충격흡수 증대와 실내밀림량 및 찌그러짐을 억제시켜, 측면충돌시 차내 승객에게 가해지는 인체상해치를 최대한 감소시키는 동시에 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 도어 하단부 보강구조를 제공하는 데 있다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle occupant protection system capable of suppressing an increase in shock absorption at the bottom of a door and an indoor jamming amount and a collapse of a door at the time of side collision of a vehicle, And to provide a reinforcing structure for a door lower portion of an automobile.
상기 목적을 달성하기 위해 본 발명은 도어의 하단 내부에 박스단면을 가지는 중공부가 구비된 강성보강용 보강판넬을 장착하고, 상기 보강판넬의 중공부에는 충격력을 흡수하는 충격흡수재를 충전하여, 차량의 측면충돌시 도어 측하단부의 실내밀림량을 줄여 인체상해치를 저감시키도록 한 것이다.In order to accomplish the above object, the present invention is characterized in that a reinforcement panel for a rigid beam having a hollow section with a box section is installed inside a lower end of a door, and a hollow portion of the reinforcement panel is filled with a shock absorber for absorbing an impact force, Thereby reducing the amount of indoor jambing at the lower portion of the door side in the event of a collision, thereby reducing the human injury value.

본 발명은 도 3 과 도 4 에 도시되는 바와 같이, 도어이너판넬(11)과 도어아웃터판넬(12)이 결합된 도어(10)에 있어서, 상기 도어(10)의 하단 내부에 결합되어 그 내부로는 박스단면을 가지는 중공부(21)가 구비된 강성보강용 보강판넬(20)과; 상기 보강판넬(20)의 중공부(21)에 충전되어 충격력을 흡수하는 충격흡수재(30)를 포함하여 구성된다.3 and 4, a door 10 having a door inner panel 11 and a door outer panel 12 coupled thereto is coupled to the inside of the lower end of the door 10, A reinforcing panel 20 for a steel rig with a hollow portion 21 having a box section; And a shock absorber 30 which is filled in the hollow portion 21 of the reinforcing panel 20 to absorb an impact force.
여기서, 상기 보강판넬(20)의 전방하부에는 충돌시 자체탄력으로 접혀지면서 충격흡수를 유도하는 탄성절곡부(22)를 절곡형성하여 구성된다.Here, the front lower portion of the reinforcing panel 20 is formed by bending a resilient bent portion 22 that is folded by itself in a collision to induce shock absorption.
상기 보강판넬(20)의 양측에는 상기 충격흡수재(30)의 이탈을 방지하는 이탈방지편(23)이 일체로 형성된다.On both sides of the reinforcing panel 20, a detachment preventing piece 23 for preventing the detachment of the shock absorber 30 is integrally formed.
상기 보강판넬(20)의 후면과 저면은 도어이너판넬(1)의 하단상에 용접으로 결합시키고, 보강판넬(20)의 전방 상단에는 플랜지를 형성하여 도어아웃터판넬(12)에 접착실러(40)로 결합시킨다.The rear and bottom surfaces of the reinforcing panel 20 are welded to the lower end of the door inner panel 1 and a flange is formed at the front upper end of the reinforcing panel 20 to attach adhesive seals 40 ).
상기 충격흡수재(30)는 충돌시 충격력을 효과적으로 흡수하는 스치로폴 또는 발포재질의 쿠션재를 충전시킨다.The shock absorber 30 is filled with a cushioning material of a styrofoam or a foam material which effectively absorbs an impact force at the time of a collision.
이와 같이 구성된 본 발명은 도어(10)의 하단 내부에 장착된 보강판넬(20)이 중공부(21)를 통해 박스단면을 형성시키고, 상기 중공부(21)에는 충격흡수재(30)가 충전되므로 도어(10) 하단부의 전체적인 결합강성이 증대된다.According to the present invention configured as described above, the reinforcement panel 20 mounted inside the lower end of the door 10 forms a box end face through the hollow portion 21, and the hollow portion 21 is filled with the shock absorber 30 The overall coupling rigidity of the lower end of the door 10 is increased.
따라서, 이러한 본 발명은 차량의 측면충돌시 1차적으로 보강판넬(20)의 전방하부에 절곡형성된 탄성절곡부(22)가 탄력적으로 접혀지면서 충격력을 흡수 및 유도하고, 2차적으로는 중공부(21)에 충전된 충격흡수재(30)가 충격력을 흡수하여 완화시키므로, 충돌시 도어(10) 하단부의 실내밀림량이 작아지고 이로 인하여 승객안전성이 향상된다.Accordingly, in the present invention, when the side collision of the vehicle occurs, the elastic bending portion 22 bent at the front lower portion of the reinforcing panel 20 is elastically folded so as to absorb and induce impact force, and secondarily, The shock absorber 30 filled in the door 21 absorbs and mitigates the impact force, so that the amount of indoor climbing at the lower end of the door 10 at the time of collision is reduced, thereby improving passenger safety.
상술한 바와 같이 본 발명은 차량의 측면충돌시 도어 하단의 충격흡수 증대와 실내밀림량 및 찌그러짐을 억제시켜, 측면충돌시 차내 승객에게 가해지는 인체상해치를 최대한 감소시키는 동시에 자동차의 안전성을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, it is possible to suppress the increase in shock absorption at the lower end of the door, the amount of indoor shrinkage and the collapse of the door at the side collision of the vehicle, thereby minimizing the human injury to passengers in the side collision, There is an effect.
