본 발명은 자동차의 범퍼 백빔에 관한 것으로서, 특히 범퍼 백빔을 지지하는 내외측타워부 사이에 범퍼 백빔을 양측부와 중앙부를 구분할 수 있는 절개홈부를 형성하여 차량 정면충돌시 또는 측면충돌시 충격이 직접 가해지는 부위 이외의 부위에는 영향을 받지않게 함으로써, 범퍼 백빔의 제기능을 충분히 발휘할 수 있게 한 자동차의 범퍼 백빔에 관한 것이다.The present invention relates to a bumper back beam of an automobile, and in particular, between the inner and outer tower parts supporting the bumper back beam, a cutout part for distinguishing the bumper back beam from both sides and the center part is formed to directly impact the vehicle during a frontal collision or a side collision. The present invention relates to a bumper back beam of an automobile in which a function other than the portion to be applied is not affected, thereby enabling the bumper back beam to fully function.

일반적으로 자동차의 범퍼 백빔은 충격흡수와 범퍼 전체를 지지하는 역할을 하게 되며, 첨부도면 제3도에 도시한 바와 같이, 보디부(11)와, 보디부의 이면부에 형성되는 양편의 내외측타워부(12),(13)로 이루어져 있다.In general, the bumper back beam of the vehicle serves to support the shock absorber and the entire bumper, and as shown in FIG. 3 of the accompanying drawings, the inner and outer towers of both sides formed on the body portion 11 and the rear portion of the body portion. It consists of parts (12) and (13).

이러한 범퍼 백빔(10)은 타워부(12),(13)에 결합되는 범퍼 스테이(20)를 이용하여 프론트 사이드 멤버(도시되지 않음)에 체결 지지된다.The bumper back beam 10 is fastened to the front side member (not shown) by using the bumper stays 20 coupled to the tower parts 12 and 13.

그러나, 이와 같은 기존의 범퍼 백빔(10)은, 첨부도면 제4도의 (a)와 (b)에 도시한 바와 같이, 차량 정면충돌시(a) 또는 차량 측면충돌시(b)에 관계없이 직접적으로 충격을 받는 부위뿐만 아니라 그 인접부위까지도 충격 영향을 받아 심하게 변형되는 단점이 있었다. 즉, 충돌방향에 관계없이 범퍼 백빔 전체에 하중이 걸려 충격 흡수효율의 저하현상을 가져오게 되는 단점이 있었다.However, such a conventional bumper back beam 10, as shown in (a) and (b) of FIG. 4 of the accompanying drawings, may be directly irrespective of the frontal collision of the vehicle or the side collision of the vehicle. As well as the area affected by the impact as well as its adjacent parts had a disadvantage of being severely deformed by the impact. That is, there is a disadvantage in that the load is applied to the entire bumper back beam irrespective of the collision direction, resulting in a decrease in shock absorption efficiency.

따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 범퍼 백빔의 양측면부와 중앙부를 구분지을 수 있도록 내외측타워부 사이에 절개홈부를 형성하여, 측면부에 가해지는 충격으로부터 중앙부가 영향을 받지않게 하고, 중앙부에 충격이 가해지는 경우에도 이와 동일한 효과를 기대할 수 있게 함으로써, 범퍼 백빔의 전체적인 충격 흡수 효율을 더욱 높일 수 있는 자동차의 범퍼 백빔을 제공하는 데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above, and the incision groove is formed between the inner and outer tower portions so as to distinguish the both side portions and the center portion of the bumper backbeam, so that the center portion is not affected by the impact applied to the side portions. It is an object of the present invention to provide a bumper back beam of an automobile which can further increase the overall shock absorption efficiency of the bumper back beam by making it possible to expect the same effect even when an impact is applied to the center portion.

이하, 첨부도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 보디부(11)와, 내외측타워부(12),(13)를 양편에 갖는 자동차의 범퍼 백빔(10)에 있어서, 상기 내측타워부(12)와 외측타워부(13) 사이에는 보디부(11)의 전면에서부터 뒷쪽으로 일정깊이 파여져 있는 절개홈부(14)가 형성되어, 보디부(11)가 외측타워부(13)를 포함하는 양편의 보디측부(11a)와, 내측타워부(12)를 포함하는 보디중앙부(11b)로 구분될 수 있게 된 것을 특징으로 한다.According to the present invention, a bumper back beam (10) of a vehicle having a body portion (11) and inner and outer tower portions (12) and (13) on both sides is provided between the inner tower portion (12) and the outer tower portion (13). An incision groove 14 is formed at a predetermined depth from the front surface of the body portion 11 to the rear side, and the body portion 11a on both sides including the outer tower portion 13 and the inner tower are formed. Characterized in that it can be divided into a body center portion (11b) comprising a portion (12).

특히, 상기 절개홈부(14)의 깊이는 보디부 전후폭 길이의 1/2을 넘지 않도록 되어 있는 것을 특징으로 한다.In particular, the depth of the incision groove 14 is characterized in that it does not exceed half of the length of the front and rear width of the body portion.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

첨부도면 제1도는 본 발명의 범퍼 백빔을 나타내는 사시도이다.1 is a perspective view showing a bumper back beam of the present invention.

여기서, 도면부호 11, 12 및 13은 범퍼 백빔의 보디부와 내외측타워부를 각각 나타낸다.Here, reference numerals 11, 12, and 13 denote body portions and inner and outer tower portions of the bumper back beam, respectively.

상기 보디부(11)의 후면에는 서로 일정한 간격을 두고 나란하게 배치되는 내외측타워부(12),(13)가 양편에 각각 일체 형성된다. 이때의 타워부(12),(13)는 보디부(11)의 두께와 동일한 두께를 갖는 사각관형상으로 이루어져 있으며, 이에 따라 범퍼 백빔(10)이 전체적으로 균일한 두께로 이루어져 있음을 알 수 있다.The inner and outer tower parts 12 and 13 which are arranged side by side at regular intervals on the rear surface of the body part 11 are integrally formed on both sides. At this time, the tower portion 12, 13 is made of a square tube shape having the same thickness as the body portion 11, it can be seen that the bumper back beam 10 is made of a uniform thickness as a whole. .

또한, 도면부호 14는 절개홈부를 나타낸다.Reference numeral 14 denotes an incision groove.

상기 절개홈부(14)는 보디부(11)의 전면에서부터 뒷쪽으로 일정깊이 파여지면서 윗쪽과 아래쪽이 개방되는 형상으로 이루어져 있다.The incision groove 14 is formed in a shape in which the top and the bottom is open while being dug deeply from the front of the body portion 11 toward the rear.

이러한 절개홈부(14)는 내측타워부(12)와 외측타워부(13) 사이에서 형성되게 되며, 홈부(14)의 양측벽은 내외측타워부(12),(13)의 각 일측벽으로 이루어질 수 있게 된다.The incision groove 14 is formed between the inner tower portion 12 and the outer tower portion 13, and both side walls of the groove portion 14 to each one side wall of the inner and outer tower portions 12, 13 It can be done.

즉, 내외측타워부(12),(13) 사이의 전체 폭에서 각 타워부의 두께만 남겨두고 절개홈부(14)가 형성되게 된다.That is, the cutting groove 14 is formed leaving only the thickness of each tower portion in the entire width between the inner and outer tower portions 12 and 13.

또한, 절개홈부(14)의 깊이는 보디부(11)의 전후폭 길이의 1/2 을 넘지 않게 된다. 이것은 절개홈부(14)에 의해 구분되는 양측부와 중앙부간의 연접부위에 대한 일정 지지강성이 유지될 수 있게 해준다.In addition, the depth of the cutout groove 14 does not exceed 1/2 of the length of the front and rear widths of the body portion 11. This makes it possible to maintain a constant support stiffness for the joint between the two sides and the center portion separated by the incision groove 14.

따라서, 범퍼 백빔의 보디부(11)는 상기 절개홈부(14)에 의해 보디중앙부(11b)와 그 양편의 보디측부(11a)로 구분될 수 있게 되며, 보디중앙부(11b)의 양편에는 각각 내측타워부(12)가 일체 구비되고, 각 보디측부(11a)의 안쪽편에는 외측타워부(13)가 구비되어, 이것들을 이용해 균형있게 지지될 수 있게 된다.Therefore, the body portion 11 of the bumper back beam can be divided into the body center portion 11b and the body side portion 11a on both sides thereof by the incision groove portion 14, respectively, on both sides of the body center portion 11b. The tower part 12 is integrally provided, and the outer side tower part 13 is provided in the inner side of each body side part 11a, and can be balanced using these.

한편, 이와 같이 구성된 범퍼 백빔(10)의 완충작용을 살펴보면 다음과 같다.On the other hand, look at the buffering action of the bumper back beam 10 configured as described above are as follows.

첨부도면 제2도의 (a)는 차량 정면충돌시 범퍼 백빔(10)의 충격흡수상태 즉, 변형상태를 나타내고 있다.2, (a) of the accompanying drawings shows a shock absorbing state, that is, a deformation state of the bumper back beam 10 during a vehicle frontal collision.

여기서, 차량 정면충돌시의 충격은 도면에 도시된 화살표와 같이 보디중앙부(11b)에 직접 가해지게 되고, 이때의 보디중앙부(11b)는 도면의 이점쇄선으로 도시한 것처럼 변형되면서 가해지는 충격을 흡수할 수 있게 된다.Here, the impact during the frontal collision of the vehicle is applied directly to the body center portion 11b as shown by the arrow shown in the figure, and the body center portion 11b at this time absorbs the impact applied while being deformed as shown by the dashed line in the figure. You can do it.

특히, 범퍼 백빔(10)의 양측부 예컨대, 보디측부(11a)는 보디중앙부(11b)와의 사이에 형성되어 있는 절개홈부(14)가 이곳(11a)으로 연결되는 충격 전달경로를 차단해주는 역할을 하게 되므로 이때의 충격에 의한 영향을 전혀 받지않게 되어 변형되지 않게 되므로, 이 보디측부(11a)와 인접한 주변 요소의 손상 예를들면, 범퍼측면 체결부의 파손 등을 최대한 방지할 수 있게 된다.In particular, both side portions of the bumper back beam 10, for example, the body side portion 11a serves to block the impact transmission path from which the cutout portion 14 formed between the body center portion 11b is connected to the excitation 11a. Therefore, since it is not affected by the impact at this time and is not deformed, damage to the peripheral element adjacent to the body side portion 11a, for example, damage to the bumper side fastening portion, etc. can be prevented as much as possible.

또한, 첨부도면 제2도의 (b)는 차량 측면충돌시의 변형상태를 나타내고 있다.In addition, FIG. 2 (b) of the accompanying drawings shows a deformation state at the time of a vehicle side collision.

여기서, 차량 측면충돌시의 충격은 보디측부(11a)에 직접 가해져 도면의 이점쇄선으로 도시된 것처럼 변형을 유발시키게 되고, 이때의 충격은 절개홈부(14)의 충격 전달경로 차단 작용에 의해 보디중앙부(11b)에 영향을 주지 못하게 된다.Here, the impact during the vehicle side impact is directly applied to the body side portion (11a) to cause deformation as shown by the dashed line in the drawing, the impact at this time is the body center portion by the impact transmission path blocking action of the incision groove 14 It does not affect (11b).

즉, 차량 측면충돌시에는 보디중앙부(11b)가 변형되지 않게 되므로 후드의 밀림 현상 등이 최대한 방지될 수 있게 된다.That is, the body center portion 11b is not deformed at the time of the side collision of the vehicle, so that the hood of the hood may be prevented as much as possible.

이상에서와 같이 본 발명은 차량 충돌방향에 관계없이 직접 충격력을 받는 부위만 국부적으로 변형 가능한 범퍼 백빔을 제공하므로서, 최소한의 변형으로 주변 요소들의 손상을 최소화하면서 최대한의 충격흡수 기능을 발휘할 수 있게 하는 장점이 있는 것이다.As described above, the present invention provides a bumper back beam that can locally deform only a part directly affected by the impact force regardless of the vehicle collision direction, thereby minimizing damage to the surrounding elements with minimal deformation, thereby enabling the maximum shock absorption function. There is an advantage.
