Description

자동차의 리어 플로어패널 보강구조Rear floor panel reinforcement structure of automobile

본 고안은 자동차의 리어 플로어패널 보강구조에 관한 것으로, 보다 상세하게는 크로스 멤버의 일측에 보강부재를 구비하여 크로스 멤버의 충격흡수율을 향상시킴은 물론 충격에 의하여 연료탱크가 파손되는 것을 사전에 방지할 수 있는 자동차의 리어 플로어패널 보강구조에 관한 것이다.The present invention relates to a rear floor panel reinforcement structure of an automobile, and more particularly, a reinforcement member is provided on one side of the cross member to improve the impact absorption rate of the cross member and to prevent the fuel tank from being damaged by the impact in advance. The rear floor panel reinforcement structure of the automobile which can be provided.

일반적으로 자동차는 크게 나누어 차체(Body)와 섀시(Chassis)로 구성되어 있으며, 차체는 자동차의 외형을 이루고 있는 부분으로, 사람의 탑승공간인 차실내와, 엔진이 설치된 기관실 및 짐을 보관하여 운반하는 트렁크 실로 구분할 수 있다. 차체는 구성 위치에 따라서 대시패널(Dash Panel)등의 내판 부분과, 기관실을 덮고 있는 후드(Hood)와 같은 외판 부분으로 구성되는 앞차체와, 프론트 플로어패널, 사이드 패널, 루프 패널, 카울 패널 및 도어 등으로 구성되는 중심차체와, 스패어 타이어나 연료탱크 등이 설치된 리어 플로어패널로 구성되는 뒤차체로 분류할 수 있다. 리어 플로어패널의 설치된 스페어 타이어(Spare Tire)와 연료탱크(Fuel Tank)의 사이에는 크로스 멤버(Cross Member)가 설치되어 있다.In general, a car is divided into a body and a chassis, and the body is a part of the car, which stores and transports the engine compartment and the engine room where the engine is installed. It can be classified as a trunk compartment. The vehicle body is composed of a front body composed of an inner plate portion such as a dash panel and an outer plate portion such as a hood covering an engine room, a front floor panel, a side panel, a roof panel, a cowl panel and It can be classified into a central vehicle body composed of a door or the like and a rear vehicle body composed of a rear floor panel provided with a spare tire or a fuel tank. A cross member is installed between the spare tire and the fuel tank installed in the rear floor panel.

도 1은 종래기술에 따른 리어 플로어패널의 구성을 보인 단면도이다. 도 1을 설명하면, 리어 플로어패널(10)의 하단 일측에 연료를 저장하는 연료탱크(12)가 설치되고, 타측에는 비상시에 손상된 타이어 대신에 사용할 수 있는 스패어 타이어(14)가 볼트(16)와 너트(18)에 의하여 리어 플로어패널(10)에 고정된다. 연료탱크(12)와 스패어 타이어(14)의 사이에는 크로스 멤버(20)가 고정된다. 크로스 멤버(20)가 리어 플로어패널(10)에 고정됨에 있어서는 용접 또는 볼트 등의 고정수단을 이용한다.1 is a cross-sectional view showing the configuration of a rear floor panel according to the prior art. Referring to FIG. 1, a fuel tank 12 for storing fuel is installed at a lower end side of the rear floor panel 10, and a spare tire 14 is provided on the other side with a spare tire 14 that can be used in place of a damaged tire in an emergency. ) And the nut 18 are fixed to the rear floor panel 10. The cross member 20 is fixed between the fuel tank 12 and the spare tire 14. When the cross member 20 is fixed to the rear floor panel 10, a fixing means such as welding or bolt is used.

상기와 같이 구성된 리어 플로어패널에 후방에서 충격이 가해지게 되면 스패어 타이어가 충격에 의하여 일측으로 이동하게 되고, 이에 따라 스패어 타이어와 연료탱크의 사이에 고정된 크로스 멤버가 일측으로 변형된다. 크로스 멤버가 스패어 타이어에 의하여 일측으로 변형됨에 따라 연료탱크가 파손되는 문제가 있었다. 또한, 크로스 멤버의 변형에 의하여 연료탱크가 파손됨에 따라 연료가 외부로 누출되고, 이에 따라 충돌사고에 따른 화재가 발생될 우려가 내포되어 있었다.When an impact is applied from the rear to the rear floor panel configured as described above, the spare tire is moved to one side by the impact, and thus the cross member fixed between the spare tire and the fuel tank is deformed to one side. As the cross member is deformed to one side by the spare tire, there is a problem that the fuel tank is damaged. In addition, as the fuel tank is damaged due to the deformation of the cross member, the fuel leaks to the outside, and thus a fire may occur due to a crash accident.

이에 본 고안은 상기한 문제를 감안하여 안출된 것으로서, 그 목적은 크로스 멤버의 일측에 보강부재를 구비하여 크로스 멤버의 충격흡수율을 향상시킴은 물론 충격에 의하여 연료탱크가 파손되는 것을 사전에 방지할 수 있는 자동차의 리어 플로어패널 보강구조를 제공함에 있다.The present invention has been devised in view of the above problems, and its purpose is to provide a reinforcing member on one side of the cross member to improve the shock absorption rate of the cross member and to prevent the fuel tank from being damaged by the impact in advance. It is to provide a rear floor panel reinforcement structure of the automobile.

이러한 본 고안의 목적은 일측 상단에 스페어 타이어가 욍볼트 및 너트에 의하여 고정되고, 타측 하단에 연료탱크가 고정되며, 스패어 타이어 및 연료탱크의 사이에 크로스 멤버가 설치된 리어 플로어패널에 있었서, 일측이 크로스 멤버의 상단에 고정되고, 타측이 리어 플로어패널에 고정되어 크로스 멤버가 연료탱크가 설치된 부분으로 변형되는 것을 제한하는 보강부재를 구비함을 특징으로 하는 자동차의 리어 플로어패널 보강구조에 의하여 달성될 수 있다.The purpose of the present invention was a spare tire is fixed on the top of one side by a shock bolt and nut, the fuel tank is fixed on the other bottom, the rear floor panel is installed between the spare tire and the fuel tank, one side Achieve by the rear floor panel reinforcement structure of the vehicle, characterized in that it is fixed to the upper end of the cross member, the other side is fixed to the rear floor panel, the reinforcing member for limiting the deformation of the cross member to the portion where the fuel tank is installed Can be.

이하, 본 고안에 따른 자동차의 리어 플로어패널 보강구조의 바람직한 실시예를 첨부 도면에 의거하여 좀 더 구체적으로 설명하면 다음과 같다.Hereinafter, a preferred embodiment of a rear floor panel reinforcement structure of a vehicle according to the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 고안에 따른 리어 플로어패널의 구성을 보인 단면도이다. 도 2 를 설명하면, 리어 플로어패널(50)의 하단 일측에 연료를 저장하는 연료탱크(55)가 설치되고, 타측에는 비상시에 손상된 타이어 대신에 사용할 수 있는 스패어 타이어(60)가 볼트와 너트에 의하여 리어 플로어패널(50)에 고정된다. 연료탱크(55)와 스패어 타이어(60)의 사이에는 크로스 멤버(65)가 고정된다. 크로스 멤버(65)가 리어 플로어패널(50)에 고정됨에 있어서는 용접 또는 볼트 등의 고정수단을 이용한다. 일측이 크로스 멤버(65)의 상단에 고정되고, 타측이 리어 플로어패널(50)에 고정되는 보강부재(70)가 구비된다. 이 보강부재(70)는 연료탱크(55)가 설치된 부분에 스폿용접에 의하여 고정된다.2 is a cross-sectional view showing the configuration of a rear floor panel according to the present invention. Referring to FIG. 2, a fuel tank 55 for storing fuel is installed at one lower end side of the rear floor panel 50, and a spare tire 60, which can be used in place of a damaged tire in an emergency, is provided with a bolt and nut. It is fixed to the rear floor panel 50 by this. The cross member 65 is fixed between the fuel tank 55 and the spare tire 60. When the cross member 65 is fixed to the rear floor panel 50, a fixing means such as welding or bolt is used. One side is fixed to the upper end of the cross member 65, the other side is provided with a reinforcing member 70 is fixed to the rear floor panel 50. The reinforcing member 70 is fixed by spot welding to the portion where the fuel tank 55 is installed.

상기와 같은 구성을 갖는 리어 플로어패널(50)에 설치된 크로스 멤버(65)에 보강부재(70)가 고정되어 있음으로 크로스 멤버(65)의 결합강도가 매우 커지게 된다. 이에 따라 외부에서 충격이 가해질 경우 보강부재(70)가 크로스 멤버(65)의 위치를 견고하게 유지시킴으로 크로스 멤버(65)가 연료탱크(55)가 설치된 부분으로 변형되는 것을 방지할 수 있는 것이다. 크로스 멤버(65)가 연료탱크(55)로 변형되는 것이 방지됨에 따라 충격에 의하여 연료탱크(55)가 파손되지 않는다.Since the reinforcing member 70 is fixed to the cross member 65 installed in the rear floor panel 50 having the above configuration, the bonding strength of the cross member 65 becomes very large. Accordingly, when an impact is applied from the outside, the reinforcing member 70 maintains the position of the cross member 65 firmly, thereby preventing the cross member 65 from being deformed into a portion in which the fuel tank 55 is installed. As the cross member 65 is prevented from being deformed into the fuel tank 55, the fuel tank 55 is not damaged by the impact.

상술한 바와 같이 본 고안에 따른 자동차의 리어 플로어패널 보강구조는 크로스 멤버의 일측에 충격에 따라 크로스 멤버가 연료탱크가 설치된 부분으로 변형되는 것을 제한하는 보강부재가 고정되어 있음으로 충격시 크로스 멤버의 충격흡수율을 향상시킴은 물론 연료탱크가 손상되는 것을 방지할 수 있는 효과를 갖는 것이다.As described above, the rear floor panel reinforcement structure of the vehicle according to the present invention has a reinforcing member that restricts the deformation of the cross member to the portion where the fuel tank is installed according to the impact on one side of the cross member. In addition to improving the shock absorption rate is to have an effect that can prevent the fuel tank from being damaged.
