본 고안은 차량용 범퍼에 관한 것으로, 특히 차량충돌시 범퍼에 가해지는 정면 및 측면충돌에너지를 효율적으로 흡수시킬 수 있도록 하여 차실내로 전달되는 충격을 최소화시키도록 된 차량용 범퍼의 충격흡수구조에 관한 것이다.The present invention relates to a bumper for a vehicle, and more particularly, to a shock absorbing structure of a bumper for a vehicle to minimize the impact transmitted to the interior of the vehicle by efficiently absorbing the front and side impact energy applied to the bumper during a vehicle crash. .
차량의 충돌사고시 차체의 손상을 막고 차실내로 전달되는 충격 및 충돌에너지를 흡수시켜 운전자나 탑승자를 최대한 보호하도록 차체의 전면에 설치시키는 범퍼는, 제2도에 도시된 것과 같이 차량의 하부프레임(1)에 범퍼스테이(2)가 직각으로 보울트(3)를 매개로 고정되면서, 상기 범퍼스테이(2)를 매개로 범퍼(4)가 취부된 구조로 되어 있다.The bumper, which is installed at the front of the vehicle to prevent damage to the vehicle body in the event of a collision and absorbs the impact and collision energy transmitted to the vehicle and provides maximum protection to the driver or occupant, is illustrated in FIG. The bumper stay 2 is fixed to the bolt 3 at right angles, and the bumper 4 is mounted via the bumper stay 2.
그러나 상기한 바와 같은 종래의 취부구조는, 범퍼스테이(2)가 하부프레임(1)에 대하여 직각으로 설치되고, 범퍼(4)를 수평방향으로 지지하도록 되어 있어, 정면충돌시에만 충격에너지를 흡수시킬 수 있고 범퍼(4)의 측면충돌시에는 범퍼(4)에 가해지는 충격에너지에 효과적으로 대항하지 못하여 충돌성능이 저하되므로, 외부의 충격에너지가 하부프레임(1)을 통해 그대로 차실내로 전달되게 되어 운전자나 탑승객의 안전을 보장할 수 없었고 차체의 손상또한 방지할 수 없게 되는 결점이 있었다.However, in the conventional mounting structure as described above, the bumper stay 2 is installed at right angles to the lower frame 1, and the bumper 4 is supported in the horizontal direction, so that the impact energy is absorbed only at the time of frontal collision. In the event of a side collision of the bumper 4, the impact performance is reduced because the impact energy applied to the bumper 4 can not be effectively prevented, so that external impact energy is transmitted to the inside of the vehicle as it is through the lower frame 1. As a result, it was impossible to guarantee the safety of the driver or passengers and to prevent damage to the vehicle body.
이에 본 고안은 상기와 같은 결점을 해결하기 위하여 안출된 것으로, 범퍼에 가해지는 정면 및 측면충돌에너지에 효율적으로 대항하도록 범퍼의 정면과 측면을 동시에 지지하여 줌으로써, 차실내로 전달되는 충격에너지를 최소화시킬 수 있도록 된 차량용 범퍼의 충격흡수구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above drawbacks, by simultaneously supporting the front and side of the bumper to effectively counter the front and side impact energy applied to the bumper, thereby minimizing the impact energy delivered to the cabin It is an object of the present invention to provide a shock absorbing structure of a vehicle bumper.
상기와 같은 목적을 달성하기 위한 본 고안은, 하부프레임의 측벽에 바깥쪽방향으로 측면지지프레임이 고정설치되고, 이 측면지지프레임과 하부프레임에 각각 스프링이 삽입된 몸체를 갖춘 제1범퍼스테이가 내설된 상태로 보울트체결됨과 더불어, 이 제1범퍼스테이의 몸체에 수용되도록 된 다른몸체를 갖춘 제2범퍼스테이가 끼워지는 한편, 이 제2범퍼스테이를 매개로 범퍼의 평면부와 곡면부가 동시에 지지되도록 구성되어 있다.The present invention for achieving the above object is, the side support frame is fixed to the side frame of the lower frame in the outward direction, the first bumper stay having a body with a spring inserted in the side support frame and the lower frame, respectively In addition to being bolted in a built-in state, a second bumper stay with a different body adapted to be accommodated is inserted into the body of the first bumper stay, while the flat part and the curved part of the bumper are simultaneously supported by the second bumper stay. It is configured to be.
이하 본 고안은 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 분리단면도로서 제2도와 동일부위에는 동일참조부호가 도시되어 있는 바, 본 고안은 차체의 하부프레임(1)의 바깥쪽 측벽에 각각 측면지지용 프레임(5)이 용접등의 체결수단을 매개로 고정설치되고, 상기 하부프레임(1)과 측면지지프레임(5) 각각에 스프링(6)이 삽입된 원통형 몸체(7)의 한쪽 끝부분에 취부구멍(8)을 갖춘 브라켓트(9)가 일체로 형성된 제1범퍼스테이(10)가, 내설된 상태로 하부프레임(1)과 측면지지프레임(5)의 앞쪽에 각각 보울트체결되는 한편, 상기 각각의 제1범퍼스테이(10)에 상기 몸체(7)에 수용될 수 있는 직경으로 이루어진 다른 몸체(11)의 한쪽 끝부분에 취부구멍(12)을 갖춘 브라켓트(13)가 일체로 형성된 제2범퍼스테이(14)가 끼워지도록 되어, 상기 브라켓트(13)를 매개로 범퍼(4)의 정면 및 측면이 동시에 보울트결합된 구조로 되어 있다.Figure 1 is a separate cross-sectional view according to the present invention is the same reference numerals are shown in the same part as the second view, the present invention is a side support frame 5 is welded to the outer side wall of the lower frame 1 of the vehicle body, respectively It is fixed via the fastening means of the back, and has a mounting hole (8) at one end of the cylindrical body (7) in which the spring (6) is inserted into each of the lower frame (1) and the side support frame (5) The first bumper stays 10 formed integrally with the brackets 9 are bolted to the front of the lower frame 1 and the side support frame 5 in a built-in state, respectively, and the respective first bumper stays ( The second bumper stay 14 is integrally formed with a bracket 13 having a mounting hole 12 at one end of the other body 11 having a diameter that can be accommodated in the body 7. The front and side surfaces of the bumper 4 are simultaneously bolted through the bracket 13. It is a hapdoen structure.
다음에는 이와같이 구성된 본 고안의 작용에 대하여 설명한다.Next, the operation of the present invention constructed as described above will be described.
제1범퍼스테이(10)와 제2범퍼스테이(14)를 매개로 설치된 범퍼(4)는, 차량충돌시 제1범퍼스테이(10)에 내설된 스프링(6)에 의하여 범퍼(4)에 가해지는 정면 및 측면충돌에너지에 대해 신축적으로 작용하며 충격을 흡수시키게 되는 바, 즉 상기 범퍼(4)의 곡면부 및 평면부가 제2범퍼스테이(14)를 매개로 설치됨과 동시에 상기 제2범퍼스테이(14)가 제1범퍼스테이(10)의 몸체(7) 길이방향을 따라 탄력운동되게 되므로, 차량충돌시 범퍼(4)에 가해지는 정면 및 측면충돌에너지에 대해 동시에 대항하게 되므로 충돌성능이 향상되게 된다.The bumper 4 provided through the first bumper stay 10 and the second bumper stay 14 is applied to the bumper 4 by a spring 6 installed in the first bumper stay 10 when the vehicle crashes. The paper elastically acts on the front and side impact energy and absorbs the shock, that is, the curved portion and the flat portion of the bumper 4 are installed through the second bumper stay 14 and the second bumper stay Since the 14 is elastically moved along the longitudinal direction of the body 7 of the first bumper stay 10, the collision performance is improved since the vehicle 14 simultaneously opposes the front and side collision energy applied to the bumper 4 during the vehicle collision. Will be.
이상 설명한 것과 같이 본 고안 차량용 범퍼의 충격흡수구조에 따르면, 범퍼에 가해지는 정면 및 측면충돌에너지에 효율적으로 대항하도록 범퍼의 평면부와 곡면부를 동시에 지지시키도록 하여, 차실내로 전달되는 충격에너지를 최소화시켜 충돌성능을 향상시킬 수 있는 효과가 있게 된다.As described above, according to the shock absorbing structure of the bumper for vehicles of the present invention, the impact energy delivered into the cabin is supported by simultaneously supporting the flat portion and the curved portion of the bumper so as to effectively counter the front and side impact energy applied to the bumper. Minimize the effect to improve the collision performance.
