Description
일반적으로 자동차는 도 1에 도시되는 바와 같이, 차체(10)의 전면부에 범퍼(20)가 전방으로 소정폭 돌출되게 취부되어, 차량의 정면 충돌시 범퍼(20)가 먼저 접촉되면서 충격을 흡수하도록 하고, 차체(10)를 통해 차량의 실내쪽에 전달되는 충격이 저감되도록 하므로, 실내에 승차한 승원이 보호되도록 되어 있다.In general, as shown in FIG. 1, the bumper 20 is mounted to the front of the vehicle body 10 in a predetermined width to protrude forward, so that the bumper 20 is first contacted when the front of the vehicle collides to absorb the shock. Since the shock transmitted to the interior of the vehicle through the vehicle body 10 is reduced, the occupant who rides in the interior is protected.
여기에서, 종래 범퍼(20)의 취부구조는 도 2에 도시되는 바와 같이, 전면 외곽을 형성하는 외피에 후면이 개구되어 소정의 수납공간이 형성되고, 외피의 양단부가 후부로 절곡 연장되어, 상기 외피의 후면 수납공간에 충격흡수부재인 포움(21)이 기밀하게 내장되고, 포움(21)의 후면에 소정폭의 평면부가 형성된 보강체(22)가 취부되며, 후부로 절곡된 보강체(22)의 후면부가 차체에 결합되는 스테이(23)에 취부되도록 되어 있다.Here, the mounting structure of the conventional bumper 20, as shown in FIG. 2, the rear surface is opened in the outer shell forming the front outer edge to form a predetermined storage space, both ends of the outer shell is bent and extended to the rear, The foam 21, which is a shock absorbing member, is airtightly embedded in the rear storage space of the outer shell, and a reinforcement 22 having a flat portion having a predetermined width is mounted on the rear surface of the foam 21, and the rear reinforcement 22 is bent. The rear part of the) is mounted to the stay 23 coupled to the vehicle body.
이와같이 구성되는 종래 자동차 범퍼의 취부구조는, 외부에서 충격하중이 작용되면, 범퍼(20)의 외피 및 포움(21)에 의해 1차적으로 충격에너지를 흡수하도록 하고, 보강체(22)가 포움(21) 및 외피를 지지하여 2차적으로 충격을 완충하도록 한다.In the conventional vehicle bumper mounting structure configured as described above, when the impact load is applied from the outside, the impact energy is primarily absorbed by the shell and the foam 21 of the bumper 20, and the reinforcement 22 forms the foam ( 21) and the outer shell to support secondary shock absorbers.
이러한 종래 자동차 범퍼의 취부구조는, 범퍼의 포움 후면에 부착되는 보강체의 접촉면이 비교적 좁은 폭으로 되어, 충격하중이 작용하는 경우 범퍼의 상단부와 하단부가 지지되지 않기 때문에 충격흡수기능이 비효율적인 단점이 있었다.In the conventional bumper mounting structure, the contact surface of the reinforcement attached to the rear surface of the bumper has a relatively narrow width, and the shock absorbing function is inefficient because the upper and lower portions of the bumper are not supported when the impact load is applied. There was this.
본 고안은 범퍼 후면부에 결합되는 보강체의 구조를 변경하여 범퍼 전면에 작용하는 충격을 효율적으로 흡수하도록 하므로 안전성이 향상되도록 하는 데 그 목적이 있다.The present invention is to change the structure of the reinforcement coupled to the rear bumper to efficiently absorb the impact acting on the front bumper is to improve the safety.

먼저, 본 고안도 도 3에 도시되는 바와 같이, 전면 외곽을 형성하는 외피의 후면이 개구되어 소정의 수납공간이 형성되고, 외피의 양단부가 후부로 절곡 연장되어, 상기 외피의 후면 수납공간에 충격흡수부재인 포움(21)이 기밀하게 내장되고, 포움(21)의 후면에 보강체(22)가 취부되며, 보강체(22)의 후면부가 차체에 결합되는 스테이에 취부되도록 된다.First, as shown in FIG. 3 of the present invention, the rear surface of the outer shell forming the front outer edge is opened to form a predetermined storage space, and both ends of the outer shell are bent and extended to the rear, impacting the rear storage space of the outer shell. The absorbent foam 21 is hermetically embedded, and the reinforcement 22 is mounted on the rear surface of the foam 21, and the rear portion of the reinforcement 22 is mounted on the stay coupled to the vehicle body.
단, 본 고안은 포움(21) 후면부에 부착되는 보강체(22)의 중간부가 소정폭 평면부로 형성되고, 상기 평면부의 상단 및 하단부에 각기 소정폭의 비이드가 절곡 형성되며, 상단부 및 하단부가 연장되어 범퍼(20) 외피의 후면 상단과 하단부에 결합됨을 그 기술적 구성상의 기본 특징으로 한다.However, in the present invention, the middle portion of the reinforcement body 22 attached to the rear portion of the foam 21 is formed as a predetermined width flat portion, the bead of predetermined width is formed at the upper and lower ends of the flat portion, respectively, and the upper and lower portions It extends and is coupled to the rear top and bottom of the bumper 20 shell is characterized in its technical configuration.
이와같이 구성되는 본 고안은, 보강체(22)가 상하방향으로 연장되어 범퍼(20)의 상단부와 하단부를 지지하므로 외부에서 충격하중이 범퍼(20) 전면에 작용되면, 범퍼(20)의 중앙에 작용되는 충돌에너지가 외피 및 포움(21)에 의해 흡수되도록 하고, 범퍼(20)의 상부와 하단부에 작용하는 충돌에너지가 보강체(22)의 상단부와 하단부에 의해 탄력적으로 흡수되도록 한다.According to the present invention configured as described above, since the reinforcement body 22 extends in the vertical direction to support the upper end and the lower end of the bumper 20, when an impact load is applied to the front of the bumper 20 from the outside, the reinforcement 22 extends in the center of the bumper 20. The impact energy to be applied is absorbed by the shell and the foam 21, and the collision energy acting on the upper and lower portions of the bumper 20 is elastically absorbed by the upper end and the lower end of the reinforcement (22).
즉, 이러한 본 고안은 범퍼(20) 후면부가 전체적으로 보강체(22)에 의해 지지되어 범퍼(20)에 작용하는 충격이 보강체(22)를 통해 골고루 분산되도록 하므로 범퍼(20)에서 흡수할 수 있는 충격에너지의 량이 증대되도록 한다.That is, the present invention can be absorbed by the bumper 20 because the bumper 20 is entirely supported by the reinforcement 22 so that the impact acting on the bumper 20 is evenly distributed through the reinforcement 22. The amount of impact energy present is to be increased.
상기와 같이 구성되고 작동되는 본 고안은, 범퍼 내부에 취부되는 보강체가 상하로 연장되어 범퍼 후면이 전체적으로 지지되도록 하므로 충격흡수 효과가 향상되도록 하는 효과가 있다.The present invention is constructed and operated as described above, the reinforcement mounted in the bumper extends up and down so that the bumper rear surface is entirely supported, thereby improving the shock absorption effect.
본 고안은 자동차 차체 전면에 취부되어 전면부 충격을 흡수하도록 하는 범퍼에 관한 것으로서, 범퍼 내부에 취부되는 보강체의 구조를 개선하여 충격흡수 효과가 향상되도록 하므로, 안전성이 향상되도록 하는데 그 목적이 있다.The present invention relates to a bumper that is mounted on the front of the vehicle body to absorb the impact of the front portion, and to improve the structure of the reinforcement mounted inside the bumper to improve the shock absorption effect, the purpose is to improve the safety. .
