It is characterized by comprising.

그리고, 상기 브라켓(10)의 노치부(12)에서 파단이 일어남에 따라 연속적으로 변형이 유도되도록 노치부(12)의 맞은편에는 접힘부(13)가 형성되는 것이 바람 직하다.In addition, it is preferable that the folding part 13 is formed on the opposite side of the notch part 12 so that deformation is continuously induced as the fracture occurs in the notch part 12 of the bracket 10.

또한, 상기 브라켓(10)의 노치부(12)와 접힘부(13)사이에는 노치부(12)에서 일어난 파단으로 브라켓(10)전체가 용이하게 파단되도록 하는 파단유도공간(15)이 형성된다.In addition, a break-inducing space 15 is formed between the notch portion 12 and the folded portion 13 of the bracket 10 so that the entire bracket 10 is easily broken by the break generated in the notch portion 12. .

한편, 상기 장착부판넬(5)에는 백빔(1)을 결합할 때, 백빔(1)이 결합되도록 하는 지지공(5a)이 형성되며, 백빔(1)과 사이드프레임(2) 중 어느 하나에 볼트가 부착되고 볼트가 통과하여 너트에 의해 서로 결합되도록 하는 고정공(5b)이 형성된다.Meanwhile, when the back beam 1 is coupled to the mounting part panel 5, a support hole 5 a is formed to couple the back beam 1 to each other, and a bolt is formed on any one of the back beam 1 and the side frame 2. And fixing holes 5b are formed to allow the bolts to pass through and to be coupled to each other by the nut.

이하, 본 발명에 따른 캐리어(3)의 파손방지구조의 작용 및 효과를 살펴본다.Hereinafter, the operation and effects of the breakage preventing structure of the carrier 3 according to the present invention will be described.

상기와 같은 구성에 따른 작동을 설명하기 위해 자동차의 운행 중 저속충돌이 일어나고 범퍼에 충격이 가해진다고 설정한다.In order to explain the operation according to the configuration described above, a low-speed collision occurs during driving of the vehicle, and the bumper is set to be applied.

상기 저속충돌로 인해 범퍼에 가해진 충격은 백빔(1)에 전달되고, 횡방향으로 설치된 백빔(1)은 굽힘이 일어나 양단부가 양측으로 벌어지는 변위가 발생한다.The impact applied to the bumper due to the low speed collision is transmitted to the back beam 1, and the horizontally installed back beam 1 is bent to generate displacements at both ends.

이때, 캐리어(3)의 장착부판넬(5)을 사이에 두고 상기 백빔(1)에 고정된 사이드프레임(2)도 같은 변위를 가지게 되고, 사이드프레임(2)에 의해 장착부판넬(5)이 이동함에 따라 장착부판넬(5)의 지그공(6) 상부의 슬릿(7)에 결합된 브라켓(10)도 영향을 받게 된다.At this time, the side frame 2 fixed to the back beam 1 with the mounting part panel 5 of the carrier 3 has the same displacement, and the mounting part panel 5 is moved by the side frame 2. As a result, the bracket 10 coupled to the slit 7 above the jig hole 6 of the mounting part panel 5 is also affected.

즉, 상기 장착부판넬(5)이 이동하면서 슬릿(7)이 벌어지고, 슬릿(7)의 양측에 고정된 브라켓(10)의 노치부(12)에는 집중하중이 걸리어 노치부(12)에서 파단유 도공간(15)로 파단이 진행된다.That is, the slit 7 is opened while the mounting unit panel 5 is moved, and the notched part 12 of the bracket 10 fixed to both sides of the slit 7 is subjected to a concentrated load so that the notched part 12 Breaking proceeds to the breaking induction space 15.

이때, 상기 브라켓(10)의 노치부(12)에서 진행된 파단이 파단유도공간(15)을 지나고, 브라켓(10)의 접힘부(13)가 펴지는 변형이 일어난다.At this time, the breaking progressed from the notched portion 12 of the bracket 10 passes through the break-inducing space 15, and the deformation of the folded portion 13 of the bracket 10 is unfolded.

즉, 상기 장착부판넬(5)이 캐리어(3)에서 더욱 횡방향으로 이동한다하여도 브라켓(10)의 접힘부(13)가 펴짐으로 인해 상기 캐리어(3)는 파손되지 않는다.That is, even if the mounting part panel 5 moves further in the carrier 3 laterally, the carrier 3 is not damaged due to the folding of the folded part 13 of the bracket 10.

따라서, 상기한 바와 같이, 본 발명에 따른 캐리어의 파손방지구조를 사용하게 되면, 사이드프레임의 벌어짐으로 인한 캐리어의 장착부판넬의 변위를 브라켓이 흡수하도록 하여 캐리어가 손상되는 것을 방지하고, 이로써 캐리어에 설치된 타부품들의 손상도 방지하는 효과를 얻을 수 있다.Therefore, as described above, when using the damage prevention structure of the carrier according to the present invention, the bracket to absorb the displacement of the mounting panel of the carrier due to the opening of the side frame to prevent the carrier from being damaged, thereby It is also possible to prevent the damage of other installed parts.
