Description
본 발명은 자동차 충돌시 충격을 흡수하기 위해서 차량의 전후방에 설치되는 범퍼 구조에 대한 것으로, 보다 상세하게는 자동차의 범퍼페이스 내부에 설치되는 범퍼빔과, 상기 범퍼빔을 차체 프레임에 연결하는 범퍼스테이 사이의 공간부에 보강부재를 설치함으로써 자동차 충돌시 충격을 다단계로 흡수 및 감소시켜 차체 프레임에 전달하는 범퍼 구조에 관한 것이다.The present invention relates to a bumper structure installed in front and rear of a vehicle in order to absorb an impact during a vehicle crash, and more particularly, a bumper stay installed inside a bumper face of a vehicle, and a bumper stay connecting the bumper beam to a vehicle body frame. The present invention relates to a bumper structure in which a reinforcing member is provided in a space between the two to absorb and reduce impacts in multiple stages during a vehicle collision and transmit the shock to a vehicle body frame.
일반적으로 충격을 흡수하기 위한 자동차의 빔 구조는 도 1에 도시한 바와 같이 차량의 외측에서 보이는 범퍼페이스(1) 내부에 차량의 좌우에 걸쳐서 설치되는 범퍼빔(2)과 상기 범퍼빔(2)을 차체 프레임(3)에 연결하는 빔퍼스테이(4), 그리고 범퍼페이스(1)와 범퍼빔(2) 사이에 삽입되는 충격흡수재(5)로 구성된다.In general, a beam structure of a vehicle for absorbing shock is a bumper beam (2) and the bumper beam (2) which is installed across the left and right of the vehicle inside the bumper face (1) as seen from the outside of the vehicle as shown in FIG. And a beam absorber 4 for connecting the vehicle body frame 3 to the vehicle body frame 3, and an impact absorbing material 5 inserted between the bumper face 1 and the bumper beam 2.
상기 범퍼 구조에 의해서 자동차 충돌시 가해진 충격을 보다 충분히 완화시켜 차체에 전달하기 위해서 종래에는, 도 2의 (a)에 도시한 바와 같이 범퍼빔(2)의 자체 두께를 증가시키고 범퍼빔(2)의 외측에 보강부재(20)를 부착하여 충돌성능을 향상시키거나, 도 2의 (b)에 도시한 바와 같이 사다리꼴 형상의 범퍼빔(2)의 내부에 가로리브(21)를 설치하고 또한 범퍼빔(2)의 외측을 감싸는 보강부재(20)를 설치함으로써 충돌성능을 향상시켰다. 하지만, 이러한 방법들은 충돌성능은 향상시키지만, 범퍼빔(2)에 추가적인 보강부재(20)가 부착되거나 범퍼빔(2) 자체의 두께가 증가하여 전체적인 중량이 증가하는 등 효과적이지 못하였다.In order to more sufficiently alleviate the impact applied to the vehicle by the bumper structure to deliver to the vehicle body, conventionally, as shown in FIG. 2A, the thickness of the bumper beam 2 is increased and the bumper beam 2 is increased. The reinforcing member 20 is attached to the outside of the bumper to improve the collision performance, or as shown in FIG. 2B, a horizontal rib 21 is provided inside the trapezoidal bumper beam 2 and the bumper is further provided. Collision performance was improved by installing a reinforcing member 20 surrounding the outside of the beam 2. However, these methods improve the collision performance, but are not effective, such as an additional reinforcing member 20 is attached to the bumper beam 2 or the thickness of the bumper beam 2 itself increases, thereby increasing the overall weight.
상기 문제점을 해결하기 위해서 본 발명은 범퍼빔과 범퍼스테이 사이의 공간부에 별도의 보강부재를 삽입 설치하여 차량의 전, 후방 충돌시 범퍼빔 및 보강부재에 의해서 다단으로 충격을 흡수 감소시킨 후 충격이 최소로 된 상태에서 차체 프레임에 전달될 수 있도록 하여 차체 프레임의 변형 및 파손을 최소화하는 범퍼구조를 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention inserts and installs a separate reinforcing member in the space between the bumper beam and the bumper stay to absorb and reduce the impact in multiple stages by the bumper beam and the reinforcing member during the front and rear collision of the vehicle.

먼저, 도 3 내지 도 5를 참조하면, 본 발명에 따르는 범퍼 구조는 차체 프레임(3)에 장착되는 범퍼스테이(4)와, 차체의 좌우 방향으로 걸쳐져 설치되는 범퍼빔(2)과, 상기 범퍼빔(2)과 범퍼스테이(4)의 사이에 삽입 설치된 보강부재(6)로 구성된다.First, referring to FIGS. 3 to 5, the bumper structure according to the present invention includes a bumper stay 4 mounted on the vehicle body frame 3, a bumper beam 2 installed in the left and right directions of the vehicle body, and the bumper. It consists of a reinforcing member 6 inserted between the beam 2 and the bumper stay 4.
도 4 및 도 5에 도시된 바와 같이 상기 범퍼스테이(4)는 볼트 등의 체결수단(40)에 의해서 차체 프레임(3)에 결합되는 차체측 패널(41)을 구비하고 있으며, 상기 차체측 패널(41)의 양측에서 연장되는 좌, 우측 패널(42, 43)로 구성된다. 상기 범퍼빔(2)은 전방면(22)과 상, 하부면(23, 24)으로 이루어져 있으며, 내부에 공간을 가지는 'ㄷ'자 형상을 가진다. 상기 내부 공간에 상기 범퍼스테이(4)의 좌,우측 패널(42, 43)이 삽입 고정된다. 또한 상기 범퍼빔(4)의 전방에는 차량의 외측을 구성하는 범퍼페이스(1)가 설치되며 상기 범퍼빔(2)과 범퍼페이스(1) 사이에는 충돌흡수재 등이 삽입될 수 있다.As shown in Figs. 4 and 5, the bumper stay 4 has a vehicle body side panel 41 which is coupled to the vehicle body frame 3 by fastening means 40 such as bolts. It consists of the left and right panels 42 and 43 extending from both sides of the 41. The bumper beam 2 includes a front surface 22 and upper and lower surfaces 23 and 24, and has a 'c' shape having a space therein. The left and right panels 42 and 43 of the bumper stay 4 are inserted into and fixed to the inner space. In addition, a bumper face 1 constituting the outside of the vehicle is installed in front of the bumper beam 4, and a collision absorber or the like may be inserted between the bumper beam 2 and the bumper face 1.
상기 범퍼스테이(4)의 좌, 우측 패널(42, 43)이 범퍼빔(2)에 삽입되면서 형성되는 공간에는 보강부재(6)가 삽입 설치된다. 보강부재(6)는 중간이 비어있는 중공의 형상을 가지며, 보강부재(6)의 일측은 상기 범퍼빔(2)의 전방면(20)과 소정의 거리를 두고 설치되며, 타측은 상기 범퍼스테이(4)의 차체측 패널(41)에 고정 결합된다.The reinforcing member 6 is inserted into the space formed while the left and right panels 42 and 43 of the bumper stay 4 are inserted into the bumper beam 2. The reinforcing member 6 has a hollow shape with an empty middle, and one side of the reinforcing member 6 is provided at a predetermined distance from the front surface 20 of the bumper beam 2, and the other side is the bumper stay. It is fixedly coupled to the vehicle body side panel 41 of (4).
이와 같은 구성을 가지는 본 발명의 범퍼 구조의 작용을 살펴보면 다음과 같다. 차량이 전방 또는 후방에서 충돌을 하게 되면 먼저 범퍼페이스(1)에 충격이 전달되고 범퍼페이스(1)는 1차적으로 충격을 흡수 감소시키면서 차량의 내측으로 밀려들어가게 된다. 이에 따라, 범퍼페이스(1)와 범퍼빔(2)의 사이에 삽입된 충격흡수재 등에 의해서 다시 한번 충격을 흡수하면서 범퍼빔(2)에 충격을 전달하게 된다.Looking at the operation of the bumper structure of the present invention having such a configuration as follows. When the vehicle collides at the front or rear, the shock is first transmitted to the bumper face 1, and the bumper face 1 is first pushed into the vehicle while absorbing and reducing the shock. Accordingly, the shock is transmitted to the bumper beam 2 while absorbing the shock once again by the shock absorber inserted between the bumper face 1 and the bumper beam 2.
이후, 2차적으로 범퍼빔(2)이 충격을 흡수하게 되고 범퍼빔(2)이 변형을 일으키면서 밀려들어가 범퍼빔(2)과 범퍼스테이(4) 사이에 설치된 보강부재(6)에 충격이 전달된다. 범퍼빔(2)으로부터 전달된 충격은 3차적으로 보강부재(6)에 의해서 흡수 감소된 후에 범퍼스테이(4)를 통해서 차체 프레임에 전달된다. 이와 같이 본 발명은 1차적으로는 범퍼페이스와 충격흡수재에 의해, 2차적으로는 범퍼빔에 의해, 그리고 3차적으로 보강부재에 의해서, 충돌시 발생하는 충격을 여러 단계로 거쳐 흡수되어 최소한의 상태로 감소된 충격을 차체 프레임에 전달할 수 있는 범퍼 구조를 구비함으로써, 차체프레임의 변형 및 파손을 최소화 할 수 있다.Subsequently, the bumper beam 2 is secondarily absorbed by the shock, and the bumper beam 2 is pushed in while deforming, thereby impacting the reinforcing member 6 provided between the bumper beam 2 and the bumper stay 4. Delivered. The impact transmitted from the bumper beam 2 is transmitted to the vehicle body frame through the bumper stay 4 after being absorbed and reduced by the reinforcing member 6. As described above, the present invention is primarily absorbed by the bumper face and the shock absorber, secondly by the bumper beam, and thirdly by the reinforcing member, by the impact generated during the collision in various stages. By providing a bumper structure that can transmit a reduced impact to the body frame, it is possible to minimize deformation and breakage of the body frame.
