본 발명은 자동차의 보강재에 관한 것으로서, 더욱 상세하게는 빽바(back bar)와 전방 롱지튜디널 프레임(front longitudinal frame) 사이에 "W"자형의 보강재를 설치하여서 차량충돌시 범퍼로부터 전달되는 충격 에너지를 효과적으로 흡수하여 차량내에 탑승한 승객의 안전을 도모하도록 해주는 자동차의 충격완화용 보강재에 관한 것이다.The present invention relates to a reinforcement of an automobile, and more particularly, by installing a "W" shaped reinforcement between a back bar and a front longitudinal frame, impact energy transmitted from a bumper during a vehicle crash. The present invention relates to a shock absorbing reinforcement for automobiles that effectively absorbs and promotes safety of passengers in a vehicle.
종래에는 제 1 도에 도시된 바와같이, 빽바(b)는 전방에 설치되는 범퍼를 고정시키는 역할을 함과 동시에 차량충돌시 범퍼로부터 전달되는 충격에너지를 흡수해주는 역할을 한다.Conventionally, as shown in FIG. 1, the rear bar b serves to fix the bumper installed at the front and to absorb the shock energy transmitted from the bumper during a vehicle crash.
또한, 이러한 빽바(b)의 후방에는 롱지튜디널 프레임(a)이 설치되어 있는데, 롱지튜디널 프레임(a)은 엔진륨의 좌우측에 설치되어 엔진을 지지해주면서 차체의 버팀쇠 역할을 하는 것으로서 차량 충돌에 대해서 충분한 강성을 갖도록 제작된다.In addition, the rear of the rear bar (b) is provided with a long ground frame (a), the long ground frame (a) is installed on the left and right sides of the engineium to support the engine as a support for the vehicle body It is manufactured to have sufficient rigidity against collision.
그런데, 종래의 빽바(b)는 얇은 판체가 그대로 롱지튜디널 프레임(a)에 부착되므로서 차량충돌시 범퍼로부터 충격력이 전달되는 경우 빽바(b)가 쉽게 변형되므로서 롱지튜디널 프레임(a)으로 전달되는 충격 에너지의 흡수가 충분하지 못하게 되어서 차체가 쉽게 변형되어 지고 차량 실내에 탑승한 승객들이 심하게 다치는 문제점이 있었다.By the way, the conventional bar (b) is a long plate body frame (a) because the thin plate is attached to the long ji frame (a) as it is when the impact force is transmitted from the bumper during a vehicle crash, the back bar (b) is easily deformed There was a problem that the body is easily deformed due to insufficient absorption of the shock energy transmitted to the vehicle and severely injured passengers in the cabin.
본 발명은 이러한 점을 감안하여 안출한 것으로서, 넓은 판체를 프레스 가공하여 다수의 돌출부를 갖는 "W"자형의 보강재를 형성하고 상기 보강재를 롱지튜디널 프레임의 전방면과 빽바 사이에 설치하므로서 차량충돌시 빽바에서 롱지튜디널 프레임으로 전달되는 충격력을 효과적으로 흡수하여 차량실내에 탑승한 승객의 안전을 도모하도록 해주는 것이 목적이다.The present invention has been made in view of this point, by pressing a wide plate to form a "W" shaped reinforcement having a plurality of protrusions, and the vehicle collision by installing the reinforcement between the front surface and the rear bar of the long ground frame The purpose is to effectively absorb the impact force transmitted from the seam bar to the LongiJi frame, to ensure the safety of passengers in the cabin.
본 발명의 이러한 목적인 다수의 돌출부를 갖는 보강재를 고정볼트를 이용하여 보강재의 구멍과 롱지튜디널 프레임의 나사공에 순차로 관통시켜서 보강재를 빽바와 롱지튜디널 프레임 사이에 설치하므로서 달성된다.The reinforcement having a plurality of protrusions, which is the object of the present invention, is achieved by sequentially passing through the holes of the reinforcement and the threaded holes of the long ground stationary frame by using the fixing bolts, and installing the reinforcing material between the rear bar and the long ground body frame.
이하, 첨부도면 제 2 도 및 제 3 도에 의거하여 본 발명을 상세히 설명하도록 한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.
차량충돌시 범퍼루부터 전달되는 충격력을 흡수하는 보강구조에 있어서, 판체를 프레스 가공하여 "W"자형의 다수의 돌출부(2a)를 가지며 구멍(2b)이 천공된 보강재(2)를 형성하고, 상기 보강재(2)를 고정볼트(3)로 롱지튜디널 프레임(1)의 전방에 체결하여서 된 것이다.In the reinforcement structure which absorbs the impact force transmitted from the bumper during vehicle crash, the plate is pressed to form a reinforcement 2 having a plurality of "W" shaped projections 2a and perforated holes 2b, The reinforcement (2) is to be fastened to the front of the long-terminal frame (1) with a fixing bolt (3).
이하, 본 발명의 작용 효과를 설명하도록 한다.Hereinafter, the effect of the present invention will be described.
먼저 넓은 판체를 "W"자형의 프레스 가공하여 다수의 돌출부(2a)를 갖도록 제작하고 일정 길이로 절단시켜서 보강재(2)를 마련한다.First, a wide plate is press-shaped into a "W" shape to have a plurality of protrusions 2a and cut into a predetermined length to prepare a reinforcing material 2.
그리고, 보강재(2)의 양측면에 구멍(2b)을 다수개 형성시킨후 롱지튜디널 프레임(1)의 전방에 형성된 나사공(1a)에 보강재(2)를 겹쳐놓고서 보강재(2)의 구멍(2b)과 롱지튜디널 프레임(1)의 나사공(1a)을 서로 일치시킨후 고정볼트(3)를 사용하여 보강재(2)를 롱지튜디널 프레임(1)에 고정시킨다.Then, after forming a plurality of holes (2b) on both sides of the reinforcing material (2), the reinforcing material (2) is superimposed on the threaded hole (1a) formed in front of the long-terminal frame (1) and the holes of the reinforcing material (2) 2b) and the screw hole (1a) of the longji frame 1 is matched with each other and then using the fixing bolt (3) to fix the reinforcement (2) to the longji frame (1).
그리고, 보강재(2)의 전방에는 빽바(4)를 설치시키도록 한다.And, the front of the reinforcing material (2) to install the back bar (4).
이와같이 구성된 상태에서, 차량충돌시 범퍼로부터 충격력이 전달되면 부의 충격에너지가 일차적으로 빽바(4)에 의해 흡수되고 난후, 보강재(2)가 찌그러지면서 이차적으로 충격에너지를 흡수하게 되며, 최종적으로 남게되는 충격에너지가 롱지튜디널 프레임(1)에서 흡수되어지게 되는 것이다.In this configuration, when the impact force is transmitted from the bumper during the collision of the vehicle, the negative impact energy is first absorbed by the rear bar 4, and then the reinforcement 2 is crushed to absorb the impact energy secondarily, and finally remains. Impact energy is to be absorbed in the long-terminal frame (1).
상기 보강재(2)는 양측이 고정볼트(3)로 롱지튜디널 프레임(1)에 고정되어 있으며, 빽바(4)측으로 돌출부(2a)가 돌설되어 있어 충격력에 대한 내구성이 우수한 것으로, 이것은 보강재(2)에서 큰 충격 에너지를 흡수하여 차체 변형량을 최소한으로 줄여줄 수 있다는 것을 의미한다.The reinforcing material (2) is fixed to the long-terminal frame (1) on both sides of the fixing bolt (3), protruding portion (2a) protruding toward the stiffening bar (4) side is excellent in durability against impact force, this is a reinforcing material ( This means that the high impact energy can be absorbed in 2) to minimize the amount of deformation of the body.
따라서, 종래의 충격흡수 구조와 다르게 빽바(4)와 롱지튜디널 프레임(1) 사이의 돌출부(2a)를 갖는 보강재(2)가 추가되므로서 차량충돌시 차체의 변형량을 최소한으로 줄여주어 차량실내에 탑승한 승객들의 안전을 도모하도록 해주는 유용한 발명이다.Therefore, unlike the conventional shock absorbing structure, the reinforcing member 2 having the protrusion 2a between the rear bar 4 and the long ground frame 1 is added, thereby reducing the amount of deformation of the vehicle body at the time of the vehicle crash to a minimum. It is a useful invention that helps to ensure the safety of passengers on board.
