Abstract
Description
본 발명은 자동차 바디 구조에 관한 것으로서, 특히 차량의 대쉬 판넬과 프론트 플로어의 접합 부위에 보강 구조를 추가하여 차량 충돌시 대쉬 판넬과 후론트 플로아의 변형을 최소화함으로서 운전자의 부상을 줄일 수 있는 충돌시 내구성 성능 향상을 위한 자동차 바디 구조에 관한 것이다.The present invention relates to a vehicle body structure, in particular, by adding a reinforcing structure to the junction of the dash panel and the front floor of the vehicle to minimize the deformation of the dash panel and the front floor during a vehicle collision in the event of a collision that can reduce the injury of the driver The present invention relates to a vehicle body structure for improving durability performance.
프레임 타입 자동차의 바디 구조에서 대쉬 판넬은 엔진룸과 운전석 사이에 위치하며, 엔진룸 방향에서 발생하는 소음과 진동이 운전석으로 유입되는 것을 차단하는 역할을 한다.In the body structure of the frame type car, the dash panel is located between the engine room and the driver's seat, and serves to block the noise and vibration generated from the engine room direction from entering the driver's seat.
또한, 프론트 플로어는 운전자와 승객의 편안한 거주 공간을 제공하기 위한 편의 장치가 장착되는 구성요소로서 충돌 사고 발생시에는 엔진룸으로부터 전해지는 충돌 에너지를 리어 플로어로 전달한다.In addition, the front floor is a component that is equipped with a convenience device for providing a comfortable living space for the driver and passengers, and in the event of a crash, the collision energy transmitted from the engine room is transferred to the rear floor.
도 1a는 대쉬 판넬과 프론트 플로어 사이의 결합 상태를 나타내는 사시도이고, 도 1b는 도 1a의 A-A 선의 선단면도이다.FIG. 1A is a perspective view illustrating a coupling state between the dash panel and the front floor, and FIG. 1B is a cross-sectional view of the A-A line of FIG. 1A.
도면에 도시되어 있는 바와 같이, 프론트 플로어(1)의 전단부에 대쉬 판넬(2)의 하부가 점용접 방식에 의해 서로 결합됨을 알 수 있다. 또한, 브라켓 바디 마운팅(3)은 프론트 플로어(1)의 하부에 보강을 위해 부착되어 있다. 도 1b를 살펴보면 구성요소들의 결합 관계를 알 수 있다.As shown in the figure, it can be seen that the lower part of the dash panel 2 is joined to each other by a spot welding method at the front end portion of the front floor 1. The bracket body mounting 3 is also attached to the lower part of the front floor 1 for reinforcement. Looking at Figure 1b it can be seen that the coupling relationship of the components.
그러나 상기한 구조로 되어 있는 자동차의 바디 구조는 측면 충돌 사고시 대쉬 판넬에서 전해지는 충격량을 실 사이드 판넬로 충분히 전달하지 못하여 대쉬 판넬의 과도한 변형과 밀림 현상이 발생하였고, 이로 인한 후론트 플로아의 변형은 운전석에 탑승하고 있는 운전자 또는 승객이 심한 부상을 입는 경우가 발생하였다.However, the body structure of the vehicle having the above-described structure does not sufficiently transmit the impact amount transmitted from the dash panel in the case of a side collision to the seal side panel, resulting in excessive deformation of the dash panel and the sliding phenomenon. Drivers or passengers in the driver's seat were seriously injured.
본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 차량의 프론트 플로어와 대쉬 판넬의 연결 부위에 거셋 대쉬를 추가하여 연결 강성을 향상시킴으로서 충돌 사고시 내구성을 향상시킬 수 있도록 한 충돌시 내구성 성능 향상을 위한 자동차 바디 구조를 제공한다.The present invention has been made to solve the above problems, by improving the connection rigidity by adding a gusset dash to the connection portion of the vehicle front floor and the dash panel to improve the durability in a crash accident to improve the durability performance in a crash To provide a car body structure.

도면을 참조하여 본 발명의 실시예를 설명하면 다음과 같다.An embodiment of the present invention will be described with reference to the drawings.
도 2a는 본 발명에 따른 대쉬 판넬과 프론트 플로어의 결합 상태를 나타내는 사시도이고, 도 2b는 B-B 선의 선단면도로서, 도면을 참조하여 본 발명을 설명하면 다음과 같다.Figure 2a is a perspective view showing a coupling state of the dash panel and the front floor according to the present invention, Figure 2b is a cross-sectional view of the line B-B, when explaining the present invention with reference to the drawings as follows.
도 2a에 도시되어 있는 바와 같이, 차량의 대쉬 판넬과 프론트 플로어를 서로 결합할 때 대쉬 판넬(10)과 프론트 플로어(20)의 결합부위에 거셋 대쉬(gusset dash)(30)를 추가로 부착하여 접합후의 강도가 향상되도록 한다. 이때의 결합 관계가 도 2b에 도시되어 있다.As shown in FIG. 2A, when the dash panel and the front floor of the vehicle are coupled to each other, a gusset dash 30 is additionally attached to the engaging portion of the dash panel 10 and the front floor 20. The strength after joining is improved. The coupling relationship at this time is shown in Figure 2b.
상기와 같은 구조를 완성하기 위해서는 먼저, 거셋 대쉬(30)를 프론트 플로어 판넬(20)의 하부에 용접과 같은 방식에 의하여 고정시키도록 한다. 또한 거셋 대쉬(30)이 고정된 후에는 종래의 기술에서와 마찬가지로 실사이드, 크로스 멤버, 바디 마운팅 브라켓과 같은 구성요소들을 차례로 용접하여 고정시킨다.In order to complete the above structure, first, the gusset dash 30 is fixed to the lower part of the front floor panel 20 by welding. In addition, after the gusset dash 30 is fixed, components such as sealside, cross member, and body mounting bracket are sequentially welded and fixed as in the related art.
거셋 대쉬(30)과 여러 구성요소들이 고정된 이후에 프론트 플로어 판넬(10)을 용접 방식에 의해 고정시키도록 한다.After the gusset dash 30 and various components are fixed, the front floor panel 10 is fixed by welding.
상기와 같이 구성된 본 발명에 의하면, 차량의 바디를 구성하는 구성요소인 대쉬 판넬과 프론트 플로어를 연결할 때, 연결 부위에 거셋 대쉬를 추가함으로서 완성된 차체 샤시의 강도가 보강되도록 하여 충돌 사고시 차량에 탑승하고 있는 운전자 또는 승객의 부상 가능성을 줄여주는 효과를 갖는다.According to the present invention configured as described above, when connecting the dash panel and the front floor, which is a component constituting the body of the vehicle, by adding a gusset dash to the connection portion so that the strength of the completed body chassis is reinforced to ride in the vehicle during a crash accident It has the effect of reducing the possibility of injury to the driver or passenger.
