Description
본 고안은 차량 플로어패널의 보강재에 관한 것으로, 리어플로어패널 끝단에 다중의 폐단면이 중첩되어 강성이 우월해진 차량 플로어패널의 보강재에 관한 것이다.The present invention relates to a reinforcement of a vehicle floor panel, and relates to a reinforcement of a vehicle floor panel in which stiffness is superior by overlapping a plurality of closed sections at the end of the rear floor panel.
일반적으로 차량에 있어 사람이 탑승하는 구성부분인 바디는 크게 외부구성부분, 내부구성부분 및 내장부분으로 구분될 수 있다.In general, a body that is a component of a person in a vehicle may be divided into an external component, an internal component, and an internal component.
여기서, 외부구성부분은 승차석을 위시하여 엔진이나 화물적재 등의 필요한 공간을 이루는 부분으로 바디의 각 아웃패널을 의미한다.Here, the external components are parts that form the necessary space, such as the engine or cargo loading, including the passenger seat means each panel of the body.
내부구성부분은 상기 외부구성부분과 함께 바디전체의 강도를 확보하는 부분으로 바디의 각 인너패널을 의미하며, 내장부분은 탑승자의 편의를 위한 각종 사일렌서나 트림류 등을 의미한다.The inner part is a part for securing the strength of the whole body together with the outer part, and means each inner panel of the body, and the inner part means various silencers or trims for the passenger's convenience.
예시도면 도 1 (가)는 상기 내부구성부분 중 웨곤형 차량의 플로어패널을 나타낸 설명도로서, 언더바디라고도 불리우는 플로어패널은 그 저부에 차량 종방향 보강재인 사이드멤버와 횡방향 보강재인 크로스멤버 등이 장착되어 차실 하부의 강성이 확보되어 있다.Exemplary Drawings Fig. 1 (A) is an explanatory view showing a floor panel of a wagon-type vehicle among the internal components, and the floor panel, also called an underbody, includes a side member that is a longitudinal longitudinal reinforcement member and a cross member that is a transverse reinforcement member at the bottom thereof. This ensures the rigidity of the lower compartment.
또한, 플로어패널 자체에도 강성을 확보하기 위하여 프론트플로어패널(1)과 리어플로어패널(2)로 구분되고 가늘고 긴 오목부나 돌출부가 성형되어 있고, 하중이 집중적으로 작용될 수 있는 부위에는 각각의 보강재가 장착되어 있다.In addition, the floor panel itself is divided into a front floor panel (1) and a rear floor panel (2) in order to ensure rigidity, and long elongated recesses or protrusions are formed, and each reinforcement material at a site where load can be concentrated. Is equipped.
예시도면 도 1 (나)는 리어플로어패널(2) 후방의 보강재를 나타낸 도 1 (가)의 A-A선 단면도로서, 리어앤드패널(3)은 바디 최후단에 장착되는 아웃패널로 웨곤형 차량의 백도어(4) 하단을 지지해주는 패널이다.Exemplary Drawing FIG. 1 (b) is a cross-sectional view taken along line AA of FIG. 1 (a) showing a reinforcement behind the rear floor panel 2, and the rear end panel 3 is an out panel mounted at the end of the body of the wagon-type vehicle. The panel supports the bottom of the back door (4).
따라서, 차량의 후방충격시 도 1 (가)에 도시된 범퍼(5)와 함께 충격물체의 차실내 침입을 저지하며, 이를 위한 리어앤드패널(3)의 강성확보를 위해 리어플로어패널(2)의 저부 끝단과 리어앤드패널(3)의 하단에는 리어크로스멤버(6)가 설치되어 있다.Accordingly, when the vehicle is impacted at the rear, the bumper 5 shown in FIG. 1 (a) prevents the intrusion of the impact object into the vehicle interior, and the rear floor panel 2 for securing the rigidity of the rear end panel 3 for this purpose. A rear cross member 6 is provided at the bottom end of the rear end and at the bottom of the rear end panel 3.
상술된 바와 같이 차실내를 구성하는 플로어패널도 강성이 확보되어야 하며 리어플로어패널(2)에는 그 저부 끝단에 백도어를 충분히 지지해주고 후방 충격에 대응하기 위해 리어크로스멤버(6)가 설치되어 있다.As described above, the floor panel constituting the interior of the vehicle body must also secure rigidity, and the rear floor panel 2 is provided with a rear cross member 6 to sufficiently support the back door at the bottom end thereof and to cope with the rear impact.
그러나, 대형사고가 점차로 확대되어 나가는 추세에 있어 단순한 하나의 폐단면으로 구성되는 리어크로스멤버(6)만으로는 차량의 후방충격에 충분히 대응치 못하였다는 문제점이 있었다.However, there has been a problem that the rear cross member 6, which is composed of a single closed cross-section, does not sufficiently cope with the rear shock of the vehicle in the trend of a large accident gradually expanding.
이에 본 고안은 상기 문제점을 해소하기 위하여 안출된 것으로, 리어플로어패널의 끝단에 다수의 폐단면이 중첩되어 그 강성이 증가된 차량 플로어패널의 보강재를 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made in order to solve the above problems, and the object of the present invention is to provide a reinforcement material for a vehicle floor panel in which a plurality of closed end surfaces are overlapped at the end of the rear floor panel and its rigidity is increased.
이를 위한 본 고안은 리어플로어패널 끝단 상부에 어퍼크로스멤버가 설치되어 리어앤드패널 상부의 강성취약이 보완되고 리어플로어패널 저부와 리어크로스멤버 사이에 인너크로스멤버가 내설되어 리어앤드패널 중·하단의 강성취약이 2중으로 보완된 것이다.In order to achieve this, the upper cross member is installed on the upper end of the rear floor panel to compensate for the weakness of the upper part of the rear end panel, and the inner cross member is installed between the bottom of the rear floor panel and the rear cross member. Rigid vulnerability is doubled.

이하 첨부된 예시도면과 함께 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
본 고안은 리어플로어패널(2) 끝단 상부에 어퍼크로스멤버(10)가 설치되고, 리어플로어패널(2)의 저부와 리어크로스멤버(6) 사이에 인너크로스멤버(12)가 설치된 구조인 차량 플로어패널의 보강재이다.The present invention is a vehicle having an upper cross member 10 is installed on the upper end of the rear floor panel 2, the inner cross member 12 is installed between the bottom of the rear floor panel 2 and the rear cross member (6). It is reinforcement of floor panel.
예시도면 도 2 는 본 고안에 따른 보강재를 나타낸 단면개요도이다.Exemplary drawing Figure 2 is a cross-sectional overview showing a reinforcing material according to the present invention.
본 고안은 종래의 리어크로스멤버(6)를 중심으로 다수의 크로스멤버를 중첩시켜 다중의 폐단면을 형성시킴으로써 리어플로어패널(2) 끝단의 강성을 증가시켰다.The present invention increases the rigidity of the end of the rear floor panel 2 by forming a plurality of closed cross-sections by overlapping a plurality of cross members around the rear cross member 6 according to the related art.
이를 위한 다수의 크로스멤버는 어퍼크로스멤버(10)와 인너크로스멤버(12)가 있으며, 분설하면 다음과 같다.A plurality of cross members for this purpose is the upper cross member 10 and the inner cross member 12, when divided as follows.
어퍼크로스멤버(10)는 도시된 바와 같이 리어플로어패널(2)의 상부에 절곡부에 장착된다. 이러한 어퍼크로스멤버(10)는 충격시 리어앤드패널(3) 상부의 뒤틀림이나 리어앤드패널(3)이 변형되고, 백도어나 충격물체가 차실내로 침입되는 것을 방지시켜 준다.The upper cross member 10 is mounted to the bent portion on the upper portion of the rear floor panel 2 as shown. The upper cross member 10 prevents the warp of the upper portion of the rear end panel 3 and the rear end panel 3 from being deformed during the impact, and prevents the back door or the impact object from entering the vehicle interior.
즉, 종래에 후방충격시 리어크로스멤버(6)가 리어앤드패널(3)을 확실히 지지시켜 주지못했던 것은 리어플로어패널(2) 끝단이 상방으로 절곡되고 절곡된 끝단에 차량 외측방으로 돌출되어 리어앤드패널(3)이 리어크로스멤버(6)와 결합되었기 때문이다.That is, the rear cross member 6 was not able to reliably support the rear end panel 3 at the time of the rear impact in the past. The end of the rear floor panel 2 was bent upward and protruded to the outside of the vehicle at the bent end. This is because the end panel 3 is coupled to the rear cross member 6.
따라서, 차량 후방충격시 리어앤드패널(3)과 리어플로어패널(2) 사이의 중공부분은 리어크로스멤버(6)에 확실히 지지되지 못하여 그 충격에 굴복이 용이한 것이다.Therefore, the hollow portion between the rear end panel 3 and the rear floor panel 2 during the rear impact of the vehicle is not securely supported by the rear cross member 6, so that it is easy to yield to the impact.
따라서, 본 고안은 리어앤드패널(3)의 상단 부위를 어퍼크로스멤버(10)가 지지토록 하여 차량 후방충격시 절단된 충격에 대응토록 하고 타부재로 분산되도록 한 것이다.Accordingly, the present invention is to allow the upper cross member 10 to support the upper end portion of the rear end panel 3 so as to cope with the impact that is cut during the rear impact of the vehicle and to be distributed to other members.
또한, 본 고안은 리어크로스멤버(6)안에 또하나의 인너크로스멤버(12)가 중첩되어 2중의 폐단면이 리어앤드패널(3)의 중단 및 하단을 지지하도록 하여 충격에너지를 효과적으로 흡수케하고 상기된 어퍼크로스멤버(10)를 지지토록 하였다.In addition, the present invention is another inner cross member 12 is superimposed in the rear cross member (6) so that the double closed end to support the interruption and the lower end of the rear end panel (3) to effectively absorb the impact energy and The upper cross member 10 was supported.
따라서, 결과적으로는 리어플로어패널(2)과 어퍼크로스멤버(10)가 이루는 폐단면, 그리고 리어앤드패널(3)과 인너크로스멤버(12)가 이루는 폐단면, 인너크로스멤버(12)와 리어크로스멤버(6)가 이루는 폐단면인 3중의 폐단면이 리어플로어패널 끝단측에 위치하여 후방충격에 대응하여 이로 인해 후방충격에 효과적으로 대응됨은 당연하다.Therefore, as a result, the closed cross section formed by the rear floor panel 2 and the upper cross member 10, and the closed cross section formed by the rear end panel 3 and the inner cross member 12, the inner cross member 12 and the rear It is natural that the triple closed cross section, which is the closed cross section formed by the cross member 6, is located at the end side of the rear floor panel to correspond to the rear shock, thereby effectively responding to the rear shock.
즉, 후방충격시 1차적으로 리어앤드패널(3)과 인너크로스멤버(12)가 이루는 폐단면이 그 충격에 대응하고, 2차적으로 인너크로스멤버(12)와 리어크로스멤버(6)가 이루는 폐단면이 그 충격을 흡수 분산시키며, 리어앤드패널(3)의 상단에 작용되는 충격은 어퍼크로스멤버(10)와 리어플로어패널(2)이 이루는 패널이 대응함으로써 후방충격이 효과적으로 흡수 분산되는 것이다.That is, the closed end surface formed by the rear end panel 3 and the inner cross member 12 primarily responds to the impact during the rear impact, and the inner cross member 12 and the rear cross member 6 secondly make the impact. The closed section absorbs and disperses the impact, and the impact acting on the upper end of the rear end panel 3 is such that the rear impact panel effectively absorbs and disperses the rear impact panel by the upper cross member 10 and the rear floor panel 2. .
상술된 바와 같이 본 고안에 따르면 리어플로어패널 끝단에 다중의 폐단면이 중첩됨으로써, 후방충격시 그 충격에너지가 효과적으로 흡수 분산되어 차량의 안전성이 향상되는 효과가 있다.As described above, according to the present invention, a plurality of closed cross-sections are overlapped at the rear floor panel ends, so that the impact energy is effectively absorbed and dispersed during rear impact, thereby improving safety of the vehicle.
