본 발명은 자동차의 범퍼(bumper)구조에 관한 것으로서, 특히 정면충돌시 충격흡수부재의 유동을 방지하고, 충격을 효과적으로 완충시켜 주도록 하는 자동차의 범퍼구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper structure of an automobile, and more particularly, to a bumper structure of a vehicle that prevents the flow of the shock absorbing member during a frontal collision and effectively cushions an impact.
종래, 자동차의 범퍼구조는, 제1도에 도시되는 바와 같이, 폐단면을 형성하는 백업비임(10)의 전면에 전면부 중간이 절개되는 충격흡수부재(20)가 부착되고, 후부가 개구되어 충격흡수부재(20)가 내부로 수납되도록 하는 범퍼외피(30)의 후단부가 백업비임(10)의 상단부와 하단부에 고정되어 있다.Conventionally, in the bumper structure of a vehicle, as shown in FIG. 1, a shock absorbing member 20 having a front half cut is attached to a front surface of a backup beam 10 forming a closed cross section, and a rear portion thereof is opened. The rear end of the bumper shell 30 to accommodate the shock absorbing member 20 therein is fixed to the upper end and the lower end of the backup beam 10.
이와같이 구성되는 종래 자동차의 범퍼구조는, 차량의 충돌시 충격흡수부재(20)를 통해 충돌에너지를 흡수하여, 백업비임(10)을 통하여 차체에 전달되는 충격을 저감시키도록 되어있다.The bumper structure of a conventional vehicle configured as described above is configured to absorb impact energy through the shock absorbing member 20 when the vehicle collides, thereby reducing the impact transmitted to the vehicle body through the backup beam 10.
그러나, 이러한 종래 자동차의 범퍼구조는, 충격흡수부재(20)의 전면부 중앙이 절개되어 범퍼외피(30) 내부면과의 사이에 공간이 형성되기 때문에, 전면부에 충격하중이나 압축 하중이 작용되면, 절개된 부위로 충격흡수부재(20)의 선단부가 유동되어 쉽게 변형되고, 완충작용을 효과적으로 하지 못하게 되는 문제점이 있었다.However, in such a bumper structure of a conventional vehicle, since the center of the front portion of the shock absorbing member 20 is cut and a space is formed between the inner surface of the bumper shell 30, an impact load or a compressive load is applied to the front portion. When the tip portion of the shock absorbing member 20 flows to the cut-out portion, the tip is easily deformed, and there is a problem that the buffering effect cannot be effectively performed.
본 발명의 목적은 상기와 같은 종래의 문제점을 보완하기 위해, 충격흡수부재의 내부에 중공부를 형성하여, 정면에 하중이 작용되는 경우, 하중이 내부의 중공부로 집중되어 흡수되도록 하는 자동차의 범퍼구조를 제공하는 데 있다.An object of the present invention is to form a hollow portion in the interior of the shock absorbing member, in order to supplement the conventional problems as described above, when the load is applied to the front, the bumper structure of the vehicle so that the load is concentrated to the hollow portion inside To provide.
이하 첨부된 도면에 의하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 발명의 범퍼도 제2도에 도시된 바와 같이, 폐단면을 형성하는 백업비임(10)의 전면에 충격흡수부재(20)가 부착되고, 후부가 개구되어 충격흡수부재(20)가 수납되도록 하는 범퍼외피(30)의 하단부와 상단부가 백업비임(10)에 체결되어, 차량의 충돌시 충격흡수부재(20)를 통해 충돌에너지를 흡수하므로, 백업임(10)을 통하여 차체에 전달되는 충격을 저감시키도록 하는 것은 종래와 같다. 단, 본 발명은 충격흡수부재(20)의 내부에 원형단면의 중공부(21)가 복수개 형성되고, 범퍼외피(30)의 중간부가 절곡되게 형성되어, 충격흡수부재(20)의 전면 절개부에 범퍼외피(30)의 중간부가 기밀하게 밀착됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2, the bumper of the present invention is provided with a shock absorbing member 20 attached to a front surface of the backup beam 10 forming a closed cross section, and a rear portion thereof is opened to accommodate the shock absorbing member 20. The lower end and the upper end of the bumper jacket 30 are fastened to the backup beam 10 so that the impact energy is absorbed through the shock absorbing member 20 when the vehicle collides, and thus the shock transmitted to the vehicle body through the backup beam 10. It is as in the prior art to reduce the. However, in the present invention, a plurality of hollow portions 21 having a circular cross section are formed inside the shock absorbing member 20, and the middle portion of the bumper shell 30 is bent to form a front cutout of the shock absorbing member 20. It is a basic feature of the technical configuration that the middle part of the bumper jacket 30 is hermetically sealed.
이와같이 구성되는 본 발명은, 범퍼외피(30)의 전면부에 충격하중이나 압축하중이 작용하는 경우, 그 하중이 충격흡수부재(20)의 내부까지 그대로 전달되어, 재질에 의한 자체 완충효과 외에, 중공부(21)의 압축작용에 의한 충격에너지 흡수 작용을 하게 된다.According to the present invention configured as described above, when the impact load or the compression load is applied to the front surface of the bumper shell 30, the load is transmitted to the inside of the shock absorbing member 20 as it is, and in addition to the self-damping effect by the material, Impact energy absorption by the compression action of the hollow portion 21 is to be.
따라서, 이러한 본 발명은, 일정이하의 하중이 범퍼외피(30)에 작용하는 경우, 충격흡수부재(20)의 전면부가 유동되지 않고 동일하게 후부까지 하중을 전달하여, 비교적 큰 충격이 작용하여도 변형이 억제되고, 충격에너지를 효과적으로 흡수하도록 한다.Therefore, in the present invention, when a load below a certain level acts on the bumper shell 30, the front portion of the shock absorbing member 20 does not flow, and the load is transmitted to the rear portion in the same way, so that a relatively large impact may be applied. Strain is suppressed and the impact energy is effectively absorbed.
이상에서 살펴본 바와 같이, 본 발명은 전면 충돌시 충격에너지를 흡수하는 동시에 충격흡수부재의 변형을 억제하여, 충돌 후에도 외관의 미려함을 유지하도록 하는 매우 유용한 것이다.As described above, the present invention is very useful to absorb the impact energy at the time of the front collision and at the same time to suppress the deformation of the shock absorbing member to maintain the beauty of the appearance after the impact.
