본 고안은 자동차용 리어프레임에 관한 것으로서, 특히, 플로어에 고정되어지는 리어프레임의 구조를 중앙에는 직선보강대가 형성되고, 직선보강대의 양측으로는 여러개의 돌편을 형성하고 있는 곡선 보강대가 형성되도록 하는 폐단면구조로 인발성형시킴으로서, 리어프레임의 강성을 향상시키는 동시에 작업공정 및 용접공정 등을 단축시킬 수 있게 되고, 알루미늄재질에 의한 인발성형작업을 하기 때문에 적은중량을 가질 수 있도록 하는 자동차용 리어 프레임의 구조에 관한 것이다.The present invention relates to a rear frame for an automobile, and in particular, a linear reinforcement is formed in the center of the structure of the rear frame fixed to the floor, and both sides of the linear reinforcement to form a curved reinforcement forming a plurality of stone pieces By drawing the closed cross-sectional structure, it is possible to improve the rigidity of the rear frame and to shorten the work process and the welding process, and to have a small weight because the pull-out work is performed by aluminum material. It is about the structure.
종래의 자동차용 리어프레임은, 제3도에 나타내었다. 즉, 판체를 모자형으로 절곡을 시켜서 리어프레임(12)을 구성하고 있다. 상기 리어프레임(12)은 양측에 절곡형성된 플랜지를 플로어(1)에 맞대은뒤 여러개소의 용접작업을 하여 고정을 시키게 된다. 따라서, 판체를 절곡시키는 작업과 여러개소의 용접작업이 필요하게 되며, 리어프레임(12)의 많은 중량이 나가게 되는 등의 문제점을 가지고 있었다.The conventional automobile rear frame is shown in FIG. In other words, the rear frame 12 is formed by bending the plate body into a hat shape. The rear frame 12 is fixed to each other by welding the flanges formed on both sides to the floor 1 after welding. Therefore, the work of bending the plate body and the welding work of several places are required, and a large weight of the rear frame 12 is exerted.
이러한 종래의 문제점등을 해결 보완하기 위한 본 고안의 목적은, 보다 가벼우면서 강성이 강한 리어프레임을 얻을 수 있도록 하고, 작업공정 및 용접공정을 단축시킬 수 있도록 하는 목적을 제공하게 된다.The object of the present invention for solving and complementing the conventional problems, such as to provide a lighter and more rigid rear frame, and to provide an object to shorten the work process and welding process.
상기의 목적을 달성하기 위하여 본 고안은, 폐단면상의 리어프레임의 내부에 직선보강대를 형성하고, 직선보강대의 양측으로는 여러개의 돌편을 돌출시키고 있는 곡선보강대가 형성되도록 인발성형시킴으로서 본 고안의 목적을 달성할 수 있게 된다.In order to achieve the above object, the present invention, by forming a linear reinforcing bar inside the rear frame on the closed cross-section, both sides of the linear reinforcing bar to form a curved reinforcing bar protruding a plurality of protrusions to form the object of the present invention Can be achieved.
이하, 첨부된 도면에 의해 본 고안을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
먼저, 제1도는 본 고안의 장착된 상태를 나타낸 사시도이고, 제2도는 본 고안 제1도의 A-A선 단면도로서, 플랜지를 양측에 형성하고 있는 모자형상의 리어프레임(2)의 내부중앙으로 직선보강대(3)를 형성시키고, 직선보강대(3)의 양측에는 내측에 여러개의 돌편(5)들을 돌출시키고 있는 곡선보강대(4)를 폐단면구조로 인발성형한 구성이다.First, FIG. 1 is a perspective view showing a mounted state of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of the first invention of the present invention. (3) is formed, and both sides of the linear reinforcing bar (3) is a configuration in which the curved reinforcing bar (4) protruding a plurality of protrusions 5 on the inside in a closed cross-sectional structure.
이와같이 된 본 고안의 작용효과를 설명하면 다음과 같다.When explaining the effect of the present invention made as follows.
먼저, 본 고안 리어프레임(2)의 내부에 형성된 직선보강대(3)와 여러개의 돌편(5)을 형성하고 있는 곡선보강대(4)는 상측과 하측에서 작용할 지도 모를 압축력에 매우 강력하게 대응을 할 수 있는 구조이므로 강성이 향상된 차체를 얻을 수 있게 된다. 또한, 본 고안의 리어프레임(2)의 구조는 폐단면구조를 이루고 있기 때문에 상,하측에서 작용되는 힘외에도 좌,우측이나 부분집중충격 등에 매우 강하게 견딜 수 있게 된다. 따라서, 리어프레임이 부러지는 일이 없게 되는 것이다. 특히, 본 고안의 리어프레임(2)은 인발작업에 의해 뽑아져 나오는 것이므로 그의 제작작업이 매우 단순하며, 아울러 인발되어나온 리어프레임(2)을 그대로 플로어(1)에 용접 고정하면 되기 때문에 판체를 일정한 규격으로 절곡하였던 종래의 불편한점과 모순점을 일소한 유용한 고안이며, 특히, 후면충돌시에 강한 성질을 갖게 된다. 또한, 알루미늄재질이므로 적은중량을 가지면서 보다 튼튼한 차체를 구성할 수 있는 효과를 가진다.First, the linear reinforcing bar (3) formed inside the rear frame (2) of the present invention and the curved reinforcing bar (4) forming a plurality of protrusions (5) can respond very strongly to the compression force that may act on the upper and lower sides. It is possible to obtain a vehicle body with improved rigidity. In addition, since the structure of the rear frame 2 of the present invention forms a closed cross-sectional structure, it is able to withstand the forces applied from the upper and lower sides, and can withstand the left and right or the partial concentrated shock very strongly. Therefore, the rear frame is not broken. Particularly, since the rear frame 2 of the present invention is drawn out by drawing work, its manufacturing work is very simple, and the rear frame 2 which is drawn out can be welded and fixed to the floor 1 as it is. It is a useful design to eliminate all the inconveniences and contradictions of the prior art bent to a certain standard, in particular, it has a strong property in the event of rear collision. In addition, since it is made of aluminum, it has the effect of constituting a more durable vehicle body with a lower weight.
