본 발명은 자동차의 센터필러에 관한 것으로, 더 상세하게 차량의 측면충돌시 센터필러 하단부의 급격한 꺽임이나 변형으로 실내밀림량이 과다해지는 것을 방지하여, 실내 승객에게 전달되는 충격량과 인체상해치를 최대한 저감시키는 동시에 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 센터필러 보강구조에 관한 것이다.The present invention relates to a center pillar of an automobile, and more particularly, it relates to a center pillar of an automobile which prevents abrupt bending or deformation of a lower portion of a center pillar at a side collision of a vehicle to prevent excessive climbing of the room, And a center pillar reinforcing structure of an automobile which can improve the safety of a car at the same time.
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 대부분에 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안진치는 미흡한 실정이다.However, although most of the cars currently produced have a certain level of safety against frontal collisions, the nystagmus for lateral collision is insufficient.
그 원인으로는 차체의 센터필러 하단부 구조가 취약하기 때문이며, 실제로 타차량과의 측면충돌시 센터필러 하단부에서 충분한 충격흡수를 유도하지 못하여 실내밀림량 과다로 인체상해치중 특히 골반부에 해당하는 펠비스(PELVIS)값이 커지기 때문이다.The reason for this is that the structure of the lower end of the center pillar of the vehicle body is weak. In fact, when the side collision with the other vehicle is not performed, sufficient shock absorption is not induced at the lower end of the center pillar. PELVIS) value is increased.
종래의 센터필러 구조는 제2도에 도시되는 바와 같이, 필러이너판넬(1)의 외측으로 사이드아웃터판넬(2)이 결합되고, 상기 사이드아웃터판넬(2)의 내부로는 보강멤버(3)가 결합되어 센터필러(4)를 구성하였기 때문에, 이러한 종래의 구조는 센터필러(4)의 지지기반이 매우 취약하므로 차량의 측면충돌시 센터필러(4)의 하단부에서 충분한 충격흡수를 유도하지 못하고 순간적인 급격한 꺽임이나 부분적인 급격한 변형이 발생하여 실내밀림량 과다로 승객에게 가해지는 충격량, 상해치가 커지는 문제점과 이로 인하여 자동차의 안전성이 떨어지게 되는 문제점이 있었다.The conventional center pillar structure has a structure in which the side outer panel 2 is coupled to the outside of the filler inner panel 1 and the reinforcing member 3 is inserted into the inside of the side outer panel 2, The center pillar 4 is constructed so that the support structure of the center pillar 4 is very weak, so that it can not induce sufficient shock absorption at the lower end of the center pillar 4 when the side collision of the vehicle occurs There has been a problem in that sudden sudden bending or partial sudden deformation occurs, the amount of impact on the passengers due to the excessive amount of indoor climbing, the increase of the injury value, and the safety of the vehicle are deteriorated.
즉, 상기와 같은 종래의 구조는 센터필러(4)가 단순히 보강멤버(3)만으로 지지되어 있기 때문에, 충돌시 어느 정도의 충격력은 흡수하지만, 그 충격력은 넘어서면 센터필러(4)의 하단부가 급격하게 변형 또는 꺽이면서 실내로 침입하게 되어 인체상해치가 커지는 문제점이 있었다.That is, in the conventional structure as described above, since the center pillar 4 is supported only by the reinforcing member 3, the impact force is absorbed to a certain degree at the time of the collision, but when the impact force is exceeded, There is a problem in that the body is injured by intrusion into the room while being rapidly deformed or bent.
본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로, 차량의 측면충돌시 센터필러 하단부의 급격한 꺽임이나 변형으로 실내밀림량이 과다해지는 것을 방지하여, 실내 승객에게 전달되는 충격량과 인체상해치를 최대한 저감시키는 동시에 자동차의 안전성을 향상시킬 수 있도록 한 자동차의 센터필러 보강구조를 제공하는 데 있다.SUMMARY OF THE INVENTION It is an object of the present invention to overcome the drawbacks of the prior art as described above and to provide a vehicle occupant protection apparatus capable of preventing an excessive amount of indoor jamming due to abrupt bending or deformation of a lower portion of a center pillar, And to provide a center pillar reinforcing structure for an automobile which can reduce the degree of human injury to the utmost and enhance the safety of an automobile.
상기 목적을 달성하기 위해 본 발명은 센터필러내의 전,후방부에 보강멤버와 보강판넬을 각각 결합시키고, 상기 보강멤버와 보강판넬에 형성된 중공부에는 압축패드를 각각 충전하여, 측면충돌시 상기 보강멤버,보강판넬이 충격을 다단으로 흡수하면서 실내밀림량을 줄일 수 있도록 한 것이다.In order to achieve the above object, the present invention is characterized in that a reinforcing member and a reinforcing panel are coupled to the front and rear portions of the center pillar, respectively, and the hollow portion formed in the reinforcing member and the reinforcing panel are filled with compression pads, Members, and reinforcement panels absorb shocks in multiple stages, thereby reducing the amount of indoor climbing.
이하 첨부된 도면에 따라서 본 발명의 구성과 작용효과를 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 제3도에 도시하는 바와 같이, 필러이너판넬(11)의 외측으로 사이드아웃터판넬(12)이 결합된 센터필러(10)에 있어서, 양단에 상기 사이드아웃터판넬(12)의 양측내면에 각각 결합되어 중앙으로는 사이드아웃터판넬(12)의 전방내면에 결합되는 돌출부(21)가 절곡형성된 보강멤버(20)와, 상기 필러이너판넬(11)의 내부에 결합되어 중앙으로는 내부에 중공부(31)가 형성되도록 돌출부(32)가 절곡형성된 보강판넬(30)과, 상기 사이드아웃터판넬(!2)가 보강멤버(20)의 양측사이에 형성된 중공부(22)(23) 및 상기 보강판넬(30)에 형성된 중공부(31)에 각각 충진되는 압축패드(40)로 구성된다.3, the center pillar 10, in which the side outer panel 12 is coupled to the outside of the filler inner panel 11, A reinforcing member 20 having a protrusion 21 bent at a center thereof to be engaged with a front inner surface of the side outer panel 12 and a reinforcing member 20 coupled to the inside of the filler inner panel 11, A reinforcing panel 30 in which the protruding portion 32 is bent so as to form the hollow portion 31 and a hollow portion 22 and 23 formed between both sides of the reinforcing member 20 in the side outer panel 2! And a compression pad (40) filled in the hollow portion (31) formed in the reinforcing panel (30).
이와 같이 구성된 본 발명은 차량의 측면충돌시 중공부(22)(23)에 압축패드(40)가 충전된 보강멤버(20)에서 일차적으로 어느 정도의 충격을 흡수하게 되고, 이어서 나머지 충격은 중공부(31)에 압축패드(40)가 내장된 보강판넬(30)에서 재차 충격을 분산, 흡수하여 완화시켜 센터필러(10)의 하단부가 실내로 밀려들어가는 것을 차단시킨다.The present invention thus constructed absorbs a certain degree of impact primarily in the reinforcing member 20 filled with the compression pad 40 in the hollow portions 22 and 23 during the side collision of the vehicle, The reinforcing panel 30 in which the compression pad 40 is embedded is dispersed and absorbed again to block the lower end of the center pillar 10 from being pushed into the room.
따라서, 이러한 본 발명은 센터필러(10)내의 전,후방부에 각각 장착된 보강멤버(20)와 보강판넬(30) 및 중공부(22)(23)(31)에 충전된 압축패드(40)를 통해 충격을 다단에 걸쳐서 흡수하기 때문에, 차량의 측면충돌시 센터필러에 가해지는 충격력을 효과적으로 흡수하므로 센터필러의 순간적인 급격한 꺽임이나 부분적인 급격한 변형을 방지하여 실내밀림량 및 인체상해치를 감소시킬 수 있다.Therefore, the present invention is applicable to the compression pads 40 (40) filled in the reinforcing member 20, the reinforcing panel 30, and the hollow portions 22, 23 and 31 respectively mounted on the front and rear portions of the center pillar 10 ) Effectively absorbs the impact force applied to the center pillar at the side collision of the vehicle, thereby preventing instantaneous sudden breaking or partial sudden deformation of the center pillar, thereby reducing the indoor shrunk amount and the human injury value .
이상에서 설명한 바와 같이 본 발명은 차량의 측면충돌시 센터필러 하단부의 급격하 꺽임이나 변형으로 실내밀림량이 과다해지는 것을 방지하여, 실내 승객에에 전달되는 충격량과 인체상해치를 최대한 저감시키는 동시에 자동차의 안전성을 향상시킬 수 있는 매우 유용한 발명이다.As described above, according to the present invention, it is possible to prevent an excessive amount of indoor jambing due to abrupt bending or deformation of a lower portion of a center pillar when a vehicle collides with a side, thereby reducing the amount of impact and human injury transmitted to a passenger in a room, Which is a very useful invention.
