본 발명은 범퍼에 관한 것이고, 특히 백비임의 어퍼 디플렉션을 효과적으로 감소시킴으로써 FMVSS나 CMVSS 등의 법규를 만족시키며 임팩트 성능을 향상시키게 되는 범퍼(bumper)에 관한 것이다.The present invention relates to a bumper, and more particularly, to a bumper that satisfies regulations such as FMVSS or CMVSS and improves impact performance by effectively reducing upper reflection of a back beam.
범퍼는 차량의 앞뒤에서 바디를 보호하기 위하여 설치되는 장치로서 충돌시 그 충격을 흡수하도록 사용된다. 종래에는 강철 재료 바디에서 약간 튀어나온 정도였으나 미국에서 대형 범퍼가 사용되게 되어 현재는 에너지 흡수 범퍼라고 불리우는 것이 일반화되어 있다. 일반적으로, 범퍼는 강철 비임과 커버의 사이에 충격흡수재가 개재되는 구조를 취하게 되고, 충격 흡수재로는 우레탄 등이 사용된다.The bumper is a device installed to protect the body in front and behind the vehicle and is used to absorb the impact in a collision. 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. In general, 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. 제1도를 참조하면, 자동차의 외관을 나타내는 사시도를 도시하며; 제2도에는 선행기술에 따른 범퍼의 구조를 나타내는, 제1도의 선 A-A를 따라 취한 단면도를 도시한다. 범퍼(50)는 백비임(52)과 범퍼 커버(54)를 포함하고, 범퍼 커버(54)는 리테이너(56)에 의해 백비임(52)에 고정된다. 상기 백비임(52)의 내부에는 강성 유지를 위해 리브(60)가 제공되며, 범퍼 커버(54)의 하부에는 외부의 공기가 엔진룸의 내부로 유동될 수 있도록 하기 위한 공기 유입부(58)가 형성된다. 도면부호 62는 범퍼의 임팩트성능 시험시 사용되는 16 인치 펜듈럼을 나타낸다.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. 1, there is shown a perspective view showing the appearance of a motor vehicle; FIG. 2 shows a sectional view taken along line A-A of FIG. 1 showing the structure of a bumper according to the prior art. The bumper 50 includes a back beam 52 and a bumper cover 54, which are secured to the back beam 52 by retainers 56. The inside of the back beam 52 is provided with a rib 60 to maintain rigidity, the lower portion of the bumper cover 54, the air inlet 58 to allow the outside air to flow into the interior of the engine room Is formed. Reference numeral 62 denotes a 16 inch pendulum used in the impact performance test of the bumper.
그러나, 상기한 바와 같이 구조되는 선행기술에 따른 범퍼(50)의 구조에 있어서는, 백비임(52)이 범퍼 커버(54)의 스킨라인에 맞추어 설계되어 상기 펜듈럼(62)의 형상과는 무관하게 되기 때문에, 상기 펜듈럼(62)에 의해 임팩트 시험을 수행할 경우, 백비임(52)의 어퍼 디플렉션(upper deflection)이 크게 나타나 임팩트 성능이 저하되고, 이로 인하여 백비임(52)의 상단부가 헤드램프 하우징 또는 라디에이터 그릴 등을 변형시키게 되어 법규를 만족시키지 못하게 되는 문제가 있었다.However, in the structure of the bumper 50 according to the prior art structured as described above, the back beam 52 is designed in accordance with the skin line of the bumper cover 54 so as to be independent of the shape of the pendulum 62. Therefore, when the impact test is performed by the pendulum 62, the upper deflection of the back beam 52 is large, so that the impact performance is lowered, whereby the upper end of the back beam 52 is headed. There was a problem that the lamp housing or the radiator grille, etc. are deformed to satisfy the regulations.
본 발명은 상기한 바와 같은 선행기술에 따른 범퍼에 내재되었던 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 백비임의 어퍼 디플렉션을 효과적으로 감소시킴으로써 FMVSS나 CMVSS 등의 법규를 만족시키며 임팩트 성능을 향상시키게 되는 범퍼를 제공함에 있다.The present invention was created to solve the problems inherent in the bumper according to the prior art as described above, an object of the present invention is to effectively reduce the upper deflection of the back beam to satisfy the regulations such as FMVSS or CMVSS and improve the impact performance It is to provide a bumper to be improved.
본 발명의 일면에 따라, 백비임과 범퍼 커버를 포함하는 범퍼가 제공되고; 상기 범퍼는, 상기 백비임의 전면에 오목부가 형성되며, 상기 백비임의 전면과 상기 범퍼 커버의 내면 사이에 에너지 업소버가 개재되는 것을 특징으로 한다.According to one aspect of the invention, there is provided a bumper comprising a back beam and a bumper cover; The bumper is characterized in that a recess is formed in the front surface of the back beam, the energy absorber is interposed between the front surface of the back beam and the inner surface of the bumper cover.
본 발명의 상기 특성에 따라, 상기 오목부와 상기 에너지 업소버에 의해 백비임의 어퍼 디플렉션이 효과적으로 감소되므로, FMVSS나 CMVSS 등의 법규를 만족시킬 수 있게 되며 임팩트 성능을 향상시킬 수 있게 된다.According to the above characteristics of the present invention, since the upper reflection of the back beam is effectively reduced by the concave portion and the energy absorber, it is possible to satisfy the regulations such as FMVSS, CMVSS, etc. and improve the impact performance.
이하, 첨부한 도면을 참조로 하여 본 발명의 바람직한 실시예를 상술하며, 도면 전체를 통하여 동일한 부분에는 동일한 도면부호를 사용하기로 한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention, the same reference numerals will be used for the same parts throughout the drawings.
제3도를 참조하면, 본 발명에 따른 범퍼의 구조를 나타내는 단면도를 도시한다. 본 발명에 따른 범퍼(10)는 백비임(12)과 범퍼 커버(14)를 포함하고, 범퍼 커버(14)는 리테이너(16)에 의해 백비임(12)에 고정된다. 상기 백비임(12)의 내부에는 강성 유지를 위해 리브(20)가 제공되며, 범퍼 커버(14)의 하부에는 외부의 공기가 엔진룸의 내부로 유동될 수 있도록 하기 위한 공기 유입부(18)가 형성된다. 도면부호 22는 범퍼의 임팩트성능 시험시 사용되는 16 인치 펜듈럼을 나타낸다.3, there is shown a cross section showing the structure of a bumper according to the invention. The bumper 10 according to the invention comprises a back beam 12 and a bumper cover 14, the bumper cover 14 being fixed to the back beam 12 by a retainer 16. The inside of the back beam 12 is provided with a rib 20 for maintaining rigidity, the lower portion of the bumper cover 14, the air inlet 18 to allow the outside air to flow into the interior of the engine room Is formed. Reference numeral 22 denotes a 16 inch pendulum used in the impact performance test of the bumper.
본 발명에 따라, 상기 백비임(12)의 전면에는 오목부(24)가 형성되고, 상기 백비임(12)의 전면과 상기 범퍼 커버(14)의 사이에는 에너지 업소버(26)가 개재된다. 상기 백비임(12)의 전면부의 형상이 상기 펜듈럼(22)의 형상과 동일하게 되므로서 임팩트 시험시 상기 백비임(12)의 어퍼 디플렉션이 감소될 수 있게 된다.According to the present invention, a recess 24 is formed on the front surface of the back beam 12, and an energy absorber 26 is interposed between the front surface of the back beam 12 and the bumper cover 14. Since the shape of the front portion of the back beam 12 is the same as the shape of the pendulum 22, the upper deflection of the back beam 12 during the impact test can be reduced.
본 발명의 상기한 바와 같은 구성에 따라, 상기 오목부와 상기 에너지 업소버에 의해 백비임의 어퍼 디플렉션이 효과적으로 감소되므로, FMVSS나 CMVSS 등의 법규를 만족시킬 수 있게 되며 임팩트 성능을 향상시킬 수 있게 된다.According to the configuration as described above of the present invention, the upper reflection of the back beam is effectively reduced by the concave portion and the energy absorber, it is possible to meet the regulations such as FMVSS, CMVSS, etc. and improve the impact performance .
