본 고안은 범퍼에 관한 것이고, 특히 백비임 코너부의 아웃터 디플렉션을 효과적으로 감소시킴으로써 펜더 패널의 변형을 방지하며 FMVSS나 CMVSS 등의 법규를 만족시키게 되는 범퍼(bumper)에 관한 것이다.The present invention relates to a bumper, and more particularly to a bumper that prevents deformation of the fender panel by effectively reducing the outer deflection of the back beam corner and satisfies the regulations such as FMVSS and CMVSS.
범퍼는 차량의 앞뒤에서 바디를 보호하기 위해 설치되는 장치로서 충돌시 충격력을 흡수하도록 사용된다. 종래에는 강철 재료 바디에서 약간 튀어나온 정도였으나 미국에서 대형 범퍼가 사용되게 되어 현재는 에너지 흡수 범퍼라고 불리우는 것이 일반화되어 있다. 범퍼는 강철 비임과 커버의 사이에 충격흡수재가 개재되는 구조를 취하게 되고, 충격 흡수재로는 우레탄 등이 사용된다.Bumpers are devices installed to protect the body from the front and back of the vehicle and are used to absorb impact forces in a crash. Conventionally, it was a little protruding from the steel material body, but large bumpers have been used in the United States, which is now commonly referred to as energy absorbing bumpers. The bumper has a structure in which a shock absorber is interposed between the steel beam and the cover, and urethane or the like is used as the shock absorber.
최근들어서는, 상기와 같은 복잡한 구조를 취하는 범퍼를 대신하여 강성유지 및 충격흡수의 양 기능을 동시에 수행하게 되는 백비임이 널리 사용되고 있다. 제 1(a)도를 참조하면, 선행기술에 따른 범퍼의 구조를 나타내는 단면도를 도시하며, 제 1(b)도에는 제 1(a) 도의 범퍼의 백비임의 외관을 나타내는 부분 사시도를 도시한다. 범퍼(50)는 백비임(52)과 범퍼 커버(54)를 포함하고, 상기 범퍼 커버(54)는 리테이너(도시안됨)에 의해 백비임(52)에 고정된다. 상기 백비임(52)의 양측방 코너부에는 각각 두개씩의 개구부(opening)(60,60a)가 마련되며, 각각의 개구부(60,60a))의 후방에는 타워(58,58a)가 돌출적으로 형성된다. 상기 타워(58,58a)의 자유단부에는 범퍼 스테이(56)가 고정되고, 상기 범퍼 스테이(56)는 사이드 멤버(도시안됨)에 고정된다. 범퍼 커버(54)의 하부에는 외부공기가 엔진룸으로 유동될 수 있도록 하기 위한 공기 유입부가 형성된다.Recently, a back beam that performs both functions of rigid maintenance and shock absorption in place of a bumper having such a complicated structure is widely used. Referring to Fig. 1 (a), a cross-sectional view showing the structure of a bumper according to the prior art is shown, and Fig. 1 (b) shows a partial perspective view showing the appearance of the back beam of the bumper of Fig. 1 (a). The bumper 50 includes a back beam 52 and a bumper cover 54, which are secured to the back beam 52 by retainers (not shown). Two openings 60 and 60a are provided at both corners of the back beam 52, respectively, and towers 58 and 58a protrude from the rear of each of the openings 60 and 60a. Is formed. A bumper stay 56 is fixed to the free ends of the towers 58 and 58a, and the bumper stay 56 is fixed to a side member (not shown). The lower part of the bumper cover 54 is provided with an air inlet for allowing external air to flow into the engine compartment.
그러나, 상기와 같은 선행기술에 따른 범퍼(50)에 있어서는, 백비임(52)의 양측방코너부에 각각 제공되는 두개의 타워(58,58a)가 서로 격설되는 방식으로 형성되기 때문에, 팬듈럼으로 범퍼(50)의 정중앙부위(0/L 부위)에 대해 임팩트 시험을 실시할 경우, 제 1(a) 도에 일점쇠선으로 도시한 바와 같이, 내측 타워(58)는 압축되어 찌그러지면 외측타워(58a)는 인장되면서 백비임(52) 코너부의 아웃터 디플렉션(outer deflection)이 커지게 되어, 임팩트 성능이 저하되고, 코너쪽에 위치되는 펜ej 패널의 부분을 변형시키게 되어 법규를 만족시키지 못하게 되는 문제가 있었다.However, in the bumper 50 according to the prior art as described above, because the two towers (58, 58a) respectively provided on both side corner portions of the back beam 52 is formed in a manner that is spaced from each other, the pandulum When the impact test is performed on the center portion (0 / L region) of the bumper 50, the inner tower 58 is compressed and crushed, as shown by the dashed line in Fig. 1 (a). 58a, the outer deflection of the corner portion of the back beam 52 is increased while being stretched, and the impact performance is deteriorated, and the portion of the penej panel located at the corner side is deformed, thereby failing to satisfy the regulations. There was a problem.
본 고안은 상기한 바와 같은 선행기술에 따른 범퍼에 내재되었던 문제점을 해결하기 위해 창안된 것으로서, 본 고안의 목적은 백비임 코너부의 아웃터 디플렉션을 효과적으로 감소시킴으로써 펜더 패널의 변형을 방지하며 FMVSS나 CMVSS 등의 법규를 만족시키게 되는 범퍼를 제공함에 있다.The present invention was devised to solve the problems inherent in the bumper according to the prior art as described above, and the object of the present invention is to effectively prevent the deformation of the fender panel by effectively reducing the outer reflection of the back beam corners and to prevent the deformation of the fender panel and the FMVSS or CMVSS. It is to provide a bumper that satisfies the law.
본 고안의 일면에 따라, 백비임과 범퍼 커버를 포함하는 범퍼가 제공되고, 상기 범펴는, 상기 백비임의 양측방 코너부에 하나씩의 개구부가 형성되며, 상기 각각의 개구부의 후방에는 하나의 타워가 돌출적으로 형성되는 것을 특징으로 한다.According to an aspect of the present invention, there is provided a bumper including a back beam and a bumper cover, wherein the bumper is formed with one opening at both corners of the back beam, and one tower is formed at the rear of each opening. It is characterized in that it is formed projecting.
본 고안의 다른 일면에 따라 상기 개구부가 리브에 의해 두개의 공간으로 나누어지게 된다.According to another aspect of the present invention, the opening is divided into two spaces by ribs.
본 고안의 상기 특성들에 따라, 임팩트시 상기 타워의 차폭방향 내면에 가해지는 충격력이 상기 리브를 통하여 상기 타워의 외면으로 전달되어 타워의 내면과 외면이 동일한 양상으로 변형되므로써, 백비임 코너부의 아웃터 디플렉션 효과적으로 감소되므로, 펜더 패널의 변형이 방지되고, FMVSS나 CMVSS 등의 법규를 만족시킬 수 있게 된다.According to the characteristics of the present invention, the impact force applied to the inner surface in the vehicle width direction at the time of impact is transmitted to the outer surface of the tower through the ribs so that the inner surface and the outer surface of the tower is transformed into the same aspect, the outer portion of the back beam corner portion Since the deflection is effectively reduced, the deformation of the fender panel is prevented, and the law such as FMVSS or CMVSS can be satisfied.
