도 1은 일반적인 차량의 전방부에 결합되는 멤버들이 도시된 사시도이다.       1 is a perspective view showing members coupled to the front of a typical vehicle.

일반적으로 차량 전방부에는 도 1에 도시된 바와 같이, 헤드램프(100), 라디에이터(200), 인터쿨러(300), 범퍼빔(400) 및 후드 래치(500)가 설치된다. 이러한 헤드램프(100), 라디에이터(200), 인터쿨러(300), 범퍼빔(400) 및 후드 래치(500)는 후술할 프론트엔드모듈의 케리어(1,2,3,4)에 장착되는데, 작업의 공정을 단순화하기 위해서 상술한 각 멤버들(100,200,300,400,500)을 장착하기 위한 기본적인 틀인 프론트엔드모듈(5)을 미리 제작하고, 상기 프론트엔드모듈(5)에 케리어(1,2,3,4)를 장착한 후, 상기 케리어(1,2,3,4)에 상기 멤버들(100,200,300,400,500)을 장착하게 된다.       In general, as shown in FIG. 1, the headlamp 100, the radiator 200, the intercooler 300, the bumper beam 400, and the hood latch 500 are installed at the front of the vehicle. The headlamp 100, the radiator 200, the intercooler 300, the bumper beam 400, and the hood latch 500 are mounted to the carriers 1, 2, 3, and 4 of the front end module to be described later. In order to simplify the process of the front end module (5), which is a basic frame for mounting each member (100, 200, 300, 400, 500) described above in advance, and the carrier (1, 2, 3, 4) to the front end module (5) After mounting, the members 100, 200, 300, 400, and 500 are mounted on the carriers 1, 2, 3, and 4.

도 2는 일반적인 차량의 프론트엔드모듈에 결합되는 케리어가 도시된 사시도이다.       2 is a perspective view illustrating a carrier coupled to a front end module of a general vehicle.

일반적인 차량의 프론트엔드모듈에 결합되는 케리어는 도 2에 도시된 바와 같이, 어퍼멤버(1), 어퍼보강재(2), 사이드멤버(3) 및 로우어멤버(4)로 구성된다. 이러한, 어퍼멤버(1), 어퍼보강재(2), 사이드멤버(3) 및 로우어멤버(4)는 용접 또는 체결부재로 서로 결합된 후, 프론트엔드모듈(5)에 장착된다.The carrier coupled to the front end module of a general vehicle is composed of an upper member 1, an upper stiffener 2, a side member 3, and a lower member 4, as shown in FIG. 2. The upper member 1, the upper reinforcing material 2, the side member 3 and the lower member 4 are coupled to each other by a welding or fastening member, and then mounted to the front end module 5.

한편, 상기 범퍼빔(400)은 크래쉬박스(6)에 의해 상기 사이드멤버(3)에 결합되는데, 상기 크래쉬박스(6)는 차량 저속 충돌시 충격을 흡수하여 차량의 파손을 최소화하기 위한 것이다. 또한, 상기 프론트엔드모듈(5)의 전방부에는 상기 범퍼빔(400)과 소정간격 이격되어 상기 범퍼빔(400)과 평행하게 하부보강재(7)가 설치되는데, 상기 하부보강재(7)는 상기 범퍼빔(400)의 강도를 보강하는 부재로써 차량 충돌시 범퍼빔(400)에 가해지는 충격량을 나누어 가지는 역할을 한다.On the other hand, the bumper beam 400 is coupled to the side member 3 by the crash box 6, the crash box 6 is to minimize the damage of the vehicle by absorbing the impact during the low speed collision of the vehicle.

상기한 효과가 있는 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.       An embodiment of the present invention having the above-described effect will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 프론트엔드모듈의 보강구조물이 도시된 사시도이고, 도 4는 도 3에 도시된 스테이부재의 사시도이다.       3 is a perspective view showing a reinforcing structure of the front end module according to the present invention, Figure 4 is a perspective view of the stay member shown in FIG.

도 3 및 도 4에는 본 발명에 따른 프론트엔드모듈의 보강구조물이 도시되어 있다. 여기서, 종래 기술과 동일한 도면부호는 동일한 부재를 나타냄을 미리 밝혀둔다.3 and 4 show the reinforcing structure of the front end module according to the present invention. Here, the same reference numerals as in the prior art indicate that the same members are represented.

도 3 및 도 4를 참조하면, 본 발명에 따른 프론트엔드모듈의 보강구조물은 차량의 FEM(Front End Module;5)에 설치되는 범퍼빔(400)과, 상기 범퍼빔(400)과 소정간격 이격되어 상기 범퍼빔(400)과 평행하게 상기 FEM(5)에 설치되는 하부보강재(7)와, 상기 범퍼빔(400) 및 하부보강재(7)에 양단이 각각 결합되어 차량 엔진으로부터 상기 FEM(5)에 전해지는 아이들진동을 저감시키기 위한 스테이부재(10)를 포함한다.3 and 4, the reinforcement structure of the front end module according to the present invention is a bumper beam 400 installed in a front end module (FEM) 5 of the vehicle, and a predetermined distance from the bumper beam 400. And both ends of the lower reinforcement material 7 installed in the FEM 5 in parallel with the bumper beam 400 and the bumper beam 400 and the lower reinforcement material 7 are respectively coupled to the FEM 5 from the vehicle engine. It includes a stay member 10 for reducing the idle vibration transmitted to).

상기 스테이부재(10)는 상기 범퍼빔(400) 및 하부보강재(7)의 형상에 대응하 여 다양한 형상으로 될 수 있는 바, 도 3에서는 상기 범퍼빔(400)이 상기 하부보강재(7)보다 차량 전방을 향해 돌출되게 설치되기 때문에, 상기 스테이부재(10)는 그 상부가 차량 전방을 향해 돌출되고 그 하부가 차량 후방을 향해 돌출되도록 절곡되어 경사진 구배부(12)가 형성된다.The stay member 10 may have various shapes corresponding to the shapes of the bumper beam 400 and the lower reinforcing material 7, and in FIG. 3, the bumper beam 400 is less than the lower reinforcing material 7. Since the stay member 10 is installed to protrude toward the front of the vehicle, the stay member 10 is bent such that its upper portion protrudes toward the front of the vehicle and its lower portion protrudes toward the rear of the vehicle, thereby forming an inclined slope 12.

상기 스테이부재(10)는 양단이 각각 상기 범퍼빔(400) 및 하부보강재(7)에 결합되어, 상기 범퍼빔(400) 및 하부보강재(7)의 길이방향으로 소정간격 이격되게 복수개 설치될 수 있다. 하지만, 원가절감 및 차체중량을 고려하여 차량 엔진으로부터 상기 FEM(5)에 전해지는 아이들진동을 효과적으로 저감시키기 위해 양단이 각각 상기 범퍼빔(400) 및 하부보강재(7)의 중간부(A,B)에 하나 결합되는 것이 바람직하다.      Both ends of the stay member 10 are coupled to the bumper beam 400 and the lower reinforcement 7, respectively, and a plurality of stay members 10 may be installed to be spaced apart at predetermined intervals in the longitudinal direction of the bumper beam 400 and the lower reinforcement 7. have. However, both ends of the bumper beam 400 and the lower reinforcement 7 are respectively disposed at both ends in order to effectively reduce idle vibration transmitted from the vehicle engine to the FEM 5 in consideration of cost reduction and vehicle weight. It is preferable to combine one).

또한, 상기 스테이부재(10)는 양단이 각각 상기 범퍼빔(400) 및 하부보강재(7)의 길이방향과 직교되는 방향으로 용접 결합될 수 있고, 볼팅이나 리벳이음으로 결합될 수도 있다.      In addition, both ends of the stay member 10 may be welded in a direction orthogonal to the longitudinal direction of the bumper beam 400 and the lower reinforcing material 7, respectively, or may be coupled by bolting or riveting.

또한, 상기 스테이부재(10)는 상기 범퍼빔에 결합되는 제 1결합부(14)가 형성되고, 상기 제 1결합부(14)로부터 연장되어 상기 하부보강재(7)에 서로 이격되게 결합되는 복수개의 제 2결합부(16)가 형성된다. 또한, 상기 제 1결합부(14)는 대략 사각형상으로 개구된 제 1개구부(14a)가 형성되고, 상기 제 2결합부(16)는 상기 제 1개구부(14a)와 소정간격 이격되어 일단이 개방되고 타단은 막혀있는 제 2개구부(16a)가 형성된다. 상기 스테이부재(10)는 제 1개구부(14a) 및 제 2개구부(16a)가 형성됨으로써, 차량 엔진으로부터 FEM(5)에 전해지는 아이들진동을 더 효과적으 로 저감시킬 수 있게 된다. 즉, 차량 엔진으로부터 발생되는 저주파진동인 아이들진동이 상기 제 1개구부(14a) 및 제 2개구부(16a)가 형성된 상기 스테이부재(10)를 지나면서 일부 감쇠된다.      In addition, the stay member 10 is a plurality of first coupling portion 14 is coupled to the bumper beam is formed, extending from the first coupling portion 14 is coupled to the lower reinforcement material 7 to be spaced apart from each other Second coupling portions 16 are formed. In addition, the first coupling portion 14 is formed with a first opening 14a opened in a substantially rectangular shape, the second coupling portion 16 is spaced apart from the first opening 14a by a predetermined interval one end A second opening 16a is formed which is open and the other end is blocked. Since the stay member 10 is formed with the first opening 14a and the second opening 16a, it is possible to more effectively reduce the idle vibration transmitted from the vehicle engine to the FEM 5. That is, the idle vibration, which is a low frequency vibration generated from the vehicle engine, is partially attenuated while passing through the stay member 10 in which the first opening 14a and the second opening 16a are formed.
