이하, 첨부된 도면을 참고로 하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
도 2는 본 발명의 바람직한 실시예에 따른 보강 구조물을 가지는 자동차 범퍼의 개략적인 단면도이다.2 is a schematic cross-sectional view of an automobile bumper having a reinforcing structure according to a preferred embodiment of the present invention.
도 2에서 도시된 바와 같이, 범퍼(100)는 외부에서 보이는 돌출부(30)와 프레임에 체결되는 체결부(40)로 크게 두 부분으로 나뉜다. 체결부(40)는 프레임(50)에 바람직하게 볼트(41)와 같은 체결 수단으로 체결된다. 돌출부(30)는 외부로 튀어나온 부분이며, 그 구성은 범퍼페이스(31)와 범퍼 페이스(31) 안쪽에 제공되어서 충돌시 충격 에너지를 흡수하는 스치로폼 류와 우레탄과 같은 재질인 흡수부(32)와 흡수부(32)의 안쪽에 제공되는 보강부(33)를 포함한다.As shown in FIG. 2, the bumper 100 is largely divided into two parts, a protrusion 30 visible from the outside and a fastening part 40 fastened to the frame. The fastening portion 40 is fastened to the frame 50 by means of fastening means, such as bolts 41. Protruding portion 30 is a portion protruding to the outside, the configuration is provided inside the bumper face 31 and the bumper face 31, absorbing portion 32 made of a material such as styrofoam and urethane absorbing impact energy during collision And a reinforcing portion 33 provided inside the absorbing portion 32.
돌출부(30)와 체결부(40) 사이의 연결은 ㄷ자 형상인 보강판(34)으로 용접 연결되어서 돌부출(30)의 길이를 길게하며, ㄷ자 형상의 보강판(34) 내부에는 ㄷ자 형상의 밀림 방지 브라켓(35)이 제공되며, 밀림 방지 브라켓(35)은 보강판(34)과 마찬가지로 보강판(34)의 내부에서 보강부(33)과 체결부(40)에 부착된다.The connection between the protruding portion 30 and the fastening portion 40 is connected by welding with a U-shaped reinforcement plate 34 to lengthen the length of the protrusion 30, and the U-shaped reinforcement plate 34 inside the U-shaped shape. An anti-rolling bracket 35 is provided, and the anti-rolling bracket 35 is attached to the reinforcing portion 33 and the fastening portion 40 inside the reinforcing plate 34 like the reinforcing plate 34.
이하, 본 발명에 따른 작용을 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described.
본 발명에 따른 자동차 범퍼(100)에 의하면 외부로 튀어나와 보이는 돌출부(30)와 프레임(50)에 체결되는 체결부(40)사이를 연결하는데 있어서, ㄷ자 형상의 보강판(34)을 제공하여 돌출부(30)의 길이를 길게하므로 돌출부(30)의 부족을 해결할 수 있으며, 보강판(34) 내부에는 밀림 방지 브라켓(34)가 제공되어서 충돌이 발생되면 충돌 에너지는 범퍼 페이스(31), 흡수부(32), 보강부(33), 보강판(34)에 의하여 충격 에너지가 감쇠되며, 또한, 돌출부(30)가 차체로 밀려오는 것을 밀림 방지 브라켓(33)이 방지하므로 차체의 손상이 최소화되어서, 탑승객으로 전달되는 충격 에너지를 최소화되며, 따라서 탑승객의 안전이 보장된다.According to the vehicle bumper 100 according to the present invention in connecting between the fastening portion 30 protruding to the outside and the fastening portion 40 fastened to the frame 50, by providing a c-shaped reinforcement plate 34 Since the length of the protrusions 30 is increased, the shortage of the protrusions 30 can be solved, and the anti-rolling bracket 34 is provided inside the reinforcement plate 34 so that the collision energy is generated when the collision occurs in the bumper face 31. The impact energy is attenuated by the part 32, the reinforcement part 33, and the reinforcement plate 34, and the anti-vibration bracket 33 prevents the protrusion 30 from being pushed into the vehicle body, thereby minimizing damage to the vehicle body. Thus, the impact energy delivered to the passengers is minimized, thus ensuring the safety of the passengers.
상기된 바와 같이, 본 발명에 따른 보강 구조물을 가지는 범퍼에 의하면, ㄷ자 형상의 보강판이 돌출부와 체결부 사이에 구비되므로 종래의 돌출부의 부족을 해결할 수 있으며, ㄷ자 형상의 보강판 내에는 체결부와 보강부 사이를 밀림 방지 브라켓이 부착되므로 충격시 범퍼의 변형을 최소화 탑승객의 안전을 향상시킬 수 있는 장점이 있다.As described above, according to the bumper having a reinforcing structure according to the present invention, since the U-shaped reinforcement plate is provided between the protrusion and the fastening portion, it is possible to solve the shortage of the conventional protrusion, and the fastening portion in the U-shaped reinforcement plate Since the anti-rolling bracket is attached between the reinforcement portion has the advantage of minimizing the deformation of the bumper during the impact to improve the safety of the passengers.
이상에서는 본 발명을 본 발명의 바람직한 실시예에 따라 설명하였지만, 본발명은 설명된 실시예에 한정되는 것은 아니며, 본 발명의 사상과 특허 청구 범위에 의해 한정되는 기술적 범주 내에서 다양한 변형과 수정이 가능함은 본 발명이 속하는 기술 분야의 당업자에게는 명백하다.While the invention has been described in accordance with preferred embodiments of the invention, the invention is not limited to the described embodiments, and various modifications and changes are possible within the technical scope defined by the spirit and claims of the invention. It is apparent to those skilled in the art that the present invention is possible.
