본 발명은 자동차의 측면충돌(side impact)대비 도어가니시(door garnish) 보강구조에 관한 것으로, 더 상세하게는 차량의 측면충돌시 도어 하단부 강성증대로 실내밀림량 감소 및 인체상해치를 줄여 자동차의 안전성을 향상시키고, 또한 도어가니시의 접촉사고시 도어의 손상을 줄여 차량유지비를 절감시킬 수 있도록 한 것이다.The present invention relates to a door garnish reinforcement structure compared to a side impact of a vehicle, and more particularly, to reduce the amount of indoor rolling and reduce the human injury by increasing the stiffness of the lower part of the door during the side impact of the vehicle. To improve the safety, and also to reduce the damage to the door in the event of a door accident contact to reduce the vehicle maintenance costs.
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 이용 하고 있다.In order to ensure the safety of passengers in the event of a car crash, there are front and side collisions, which are important factors to secure the safety of cars. I use it as an item.
그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면층돌에 대한 안전치는 미흡한 실정이다.However, most of the automobiles currently produced have a certain level of safety against frontal collisions, but the level of safety against sidewalls is insufficient.
그 원인으로는 자동차의 도어 하단부가 취약하여 차량의 측면충돌시 도어에서 충격력을 충분히 흡수하지 못하므로 도어가 차안으로 밀려들어가기 때문에 승객 상해치가 커지기 때문이다.This is because the lower part of the door of the car is weak, so that the impact force is not sufficiently absorbed by the door during the side collision of the car, so the door is pushed into the car, resulting in increased passenger injury.
일반적으로 종래의 도어가니시 장착구조는 제2도에 도시되는 바와 같이, 도어이너판넬(1)과 도어이너판넬(2)로 이루어진 도어(3)의 상기 도어이너판넬(1) 하단에 천공된 체결공(4)에 도어가니시(5)의 배면으로 돌출된 클립(6)을 끼워서 장착하는 구조로 구성된다.In general, the conventional door garnish mounting structure is perforated to the bottom of the door inner panel 1 of the door (3) consisting of a door inner panel (1) and the door inner panel (2) as shown in FIG. The fastening hole 4 is configured to fit the clip 6 protruding to the rear surface of the door garnish (5).
따라서, 이와 같은 종래의 구조는 단순히 도어이너판넬(1)의 하단에 형성된 체결공(4)에 클립(6)을 끼워서 도어가니시(5)를 도어(30)의 하단부에 장착하였기 때문에 , 도어(3)의 강성이 취약하여 차량의 측면충돌시 도어(3)에서 자체적으로 충격력을 충분히 흡수할 수 없어 충돌시 도어(3)가 그대로 차안으로 과다하게 밀려들어가 인체상해치가 커지고, 이로 인하여 자동차의 안전성이 떨어지는 문제점이 있었다.Therefore, such a conventional structure simply attaches the clip 6 to the fastening hole 4 formed at the lower end of the door inner panel 1 so that the door garnish 5 is mounted at the lower end of the door 30, so that the door (3) The rigidity of the vehicle is weak, so that the impact of the impact on the door (3) itself can not be sufficiently absorbed in the side collision of the vehicle, the door (3) is pushed excessively into the car in the event of a collision, the injury to the human body increases, There was a problem of poor safety.
또한, 상기에서와 같이 도어(3)의 강성이 취약한 관계로 도어가니시(5)의 차량접촉사고등으로 인한 사소한 충격에도 도어(3)가 쉽게 손상되어 차량유지비가 많이 소요되는 문제점이 있었다.In addition, since the rigidity of the door 3 is weak as described above, there is a problem that the door 3 is easily damaged even by a slight impact caused by a vehicle contact accident of the door garnish 5, and thus, a lot of vehicle maintenance costs are required.
본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 발명한 것으로, 차량의 측면충돌시 도어 하단부 강성증대로 실내밀림량 감소 및 인체상해치를 줄여 자동차의 안전성을 향상시키고, 또한 도어가니시의 접촉사고시 도어의 손상을 줄여 차량유지비를 절감시킬 수 있도록 한 자동차의 측면충돌대비 도어가니시 보강구조를 제공하는 데 있다.The object of the present invention is to invent the above-mentioned conventional drawbacks, and to reduce the amount of indoor sliding and reduce the human injury by increasing the rigidity of the lower end of the door during side collision of the vehicle, thereby improving the safety of the car, It is to provide a door garnish reinforcement structure against a side collision of a car to reduce the damage of the door in case of a contact accident and to reduce the vehicle maintenance cost.
상기 목적을 달성하기 위해 본 발명은 도어이너판넬의 하단에 내측으로 절곡되는 도어홈을 형성하고, 상기 도어홈의 후방과 도어이너판넬의 하단에 이너보강부재를 장착하며, 상기 도어홈내에는 아웃터보강부재를 설치하며, 상기 아웃터보강부재에는 중공부가 구비된 도어가니시를 장착하여, 도어 하단부강성을 증대 시킨 것이다.In order to achieve the above object, the present invention forms a door groove which is bent inwardly at the bottom of the door inner panel, and mounts an inner reinforcing member at the rear of the door groove and the bottom of the door inner panel, and in the door groove The reinforcing member is installed, and the outer reinforcing member is equipped with a door garnish provided with a hollow portion, thereby increasing the bottom rigidity of the door.
이하 첨부된 도면에 따라서 본 발명의 구성과 작용효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and effect of the present invention according to the accompanying drawings in detail.
본 발명의 제3도에 도시되는 바와 같이, 도어이너판넬(10)의 하단에서 내측으로 절곡시켜 구비된 도어홈(11)과, 상기 도어홈(11)의 후방과 도어이너판넬(20)의 하단에 용접 및 볼트(60),너트(61) 체결로 결합되는 이너보강부재(30)와, 상기 도어홈(11)내에 용접으로 부착되어 중앙으로 클립홀(41)이 천공된 아웃터보강부재(40)와, 상기 클립홀(41)에 결합되는 클립(51)을 구비하여 도어홈(11)의 전방에 장착되어 내부 중앙으로는 충격흡수용 중공부(52)가 구비된 도어가니시(50)로 구성 된다.As shown in FIG. 3 of the present invention, the door groove 11 provided by bending inward from the lower end of the door inner panel 10, the rear of the door groove 11 and the door inner panel 20 Inner reinforcing member 30 coupled by welding and bolt 60 and nut 61 fastening at the lower end, and outer reinforcing member attached to the door groove 11 by welding and having a hole in the center of the clip hole 41 ( 40 and a door 51 having a clip 51 coupled to the clip hole 41 and mounted at the front of the door groove 11 and having a hollow portion 52 for shock absorption in the inner center thereof. It consists of).
상기 이너보강부재(30)는 대략형으로 절곡형성하여 저면과 일측면은 상기 도어이너판넬(20)의 하단에 용접으로 고정시키고, 타측면은 상기 도어이너판넬(10)의 하단에 볼트(60)와 너트(61) 체결로 고정시킨다. 이때, 볼트(60)는 상기 아웃 터보강부재(40)에 형성된 플립홀(41)을 통해 이너보강부재(30)에 용접된 너트(61)d 체결된다.The inner reinforcing member 30 is approximately The bottom surface and one side are fixed by welding to the lower end of the door inner panel 20 by forming a bent shape, and the other side is fixed to the bottom of the door inner panel 10 by fastening the bolt 60 and the nut 61. Let's do it. At this time, the bolt 60 is fastened to the nut 61 d welded to the inner reinforcing member 30 through the flip hole 41 formed in the out turbo steel member 40.
상기 아웃터보강부재(40)는 대략형으로 절곡형성하여 그 상,하부를 도어홈(11)의 상,하부에 각각 용접으로 부착시킨다.The outer reinforcing member 40 is approximately It is bent into a shape and attached to the upper and lower portions of the upper and lower portions of the door groove 11 by welding.
이와 같이 구성된 본 발명은 도어홈(11)내에 장착된 아웃터보강부재(40)와 도어의 하단내에 장착된 이너보강부재(30)에 의해 도어 하단부의 강성이 증대됨은 물론 도어가니시(50)내에 형성된 중공부(52)에 의해 충격력을 충분히 흡수할 수 있는 구조로 구성되었기 때문에 도어가 자체적으로 충격력을 감소시킬 수 있다.The present invention configured as described above increases the rigidity of the lower end of the door by the outer reinforcing member 40 mounted in the door groove 11 and the inner reinforcing member 30 mounted in the lower end of the door, as well as in the door varnish 50. Since the hollow part 52 is formed to have a structure capable of sufficiently absorbing the impact force, the door itself may reduce the impact force.
즉, 차량의 측면충돌시 도어의 하단에 장착된 도어가니시(50)가 중공부(52)를 통해 일차적으로 어느 정도의 충격을 흡수하게 되고, 이어서 나머지 충격은 아웃터보강부재(40)와 이너보강부재(30)에 의해 순차적으로 분산,흡수되면서 완화된다.That is, when the side collision of the vehicle, the door garnish 50 mounted on the lower end of the door absorbs a certain degree of shock primarily through the hollow portion 52, and then the remaining impact is the outer reinforcing member 40 and the inner The reinforcing member 30 is relaxed while being dispersed and absorbed sequentially.
여기서 도어홈(11)에 장착된 도어가니시(50),아웃터보강부재(40)와 이너보강판넬(30)은 충격흡수 뿐 아니라 도어의 전체적인 강성을 증대시켜 도어가 차안으로 밀리지않게 함과 동시에 손상을 방지한다.The door garnish 50, the outer reinforcing member 40 and the inner reinforcing panel 30 mounted on the door groove 11 not only absorb shock but also increase the overall rigidity of the door so that the door is not pushed into the car. Prevent damage.
따라서, 리러한 본 발명은 차량의 측면충돌시 강성이 보강된 도어가 자체적으로 충격력을 감소시켜 승객의 안전을 극대화시키고, 또한 접촉사고시 도어 손상을 방지하여 차량유지비를 절감 시킬 수있다.Therefore, the present invention can reduce the vehicle maintenance cost by maximizing the safety of the passenger by reducing the impact force of the door itself is reinforced by the rigidity of the side collision of the vehicle, and also prevent the door damage in case of a contact accident.
이상에서 설명한 바와 같이 본 발명은 차량의 측면충돌시 도어 하단부 강성증대로 실내밀림량 감소 및 인체상해치를 줄여 자동차의 안전성을 향상시키고, 또한 도가니시의 접촉사고시 도어의 손상을 줄여 차량유지비를 절감시킬 수 있는 매우 유용한 발명이다.As described above, the present invention improves the safety of the vehicle by reducing the amount of indoor sliding and reducing the human injury by increasing the stiffness of the lower end of the door during side collision of the vehicle, and also reduces the maintenance cost of the vehicle by reducing the damage of the door in the event of a crucible contact. Is a very useful invention.
