Description
본 발명은 차량의 충돌시 파손을 방지하여 안정성을 높인 연료탱크에 관한 것이다.The present invention relates to a fuel tank having improved stability by preventing damage during a collision of a vehicle.
연료탱크는 연료를 저장하는 것으로서 파손시 화재 위험성이 높으므로 통상 후방 좌석 하부의 차체 바닥에 장착하고 있다.The fuel tank is a fuel storage device and is usually mounted on the floor of the lower body of the rear seat because of the high risk of fire in case of breakage.
그리고, 측면충돌에 대비하여 도 2 에 도시하는 것과 같이 연료탱크(10)옆에 사이드멤버(11)와 사이드실(Side Sill,12)로 보호장벽을 구축하여 연료탱크(10)에 충격이 가해지는 것을 차단하고 있다.And, in preparation for the side impact as shown in FIG. 2, a protective barrier is formed by the side member 11 and the side seal 12 next to the fuel tank 10, and the fuel tank 10 is impacted. It is blocking you from losing.
그러나 상기한 구조는 연료탱크(10)를 안전하게 보호하기 위해서는 사이드멤버(11)와 사이드실(12)로 구성된 보호 장벽이 커지고 강도가 보강되어야 하므로 무게 및 비용 증가의 원인이 되고 있으며 측면 충돌에 의해 사이드실(12)과 사이드멤버(11)가 변형된후 연료탱크(10)에 충격에너지가 가해지면 연료탱크(10)가 터지고 연료가 흘러나와 화재의 위험이 높다는 문제점이 있었다.However, in order to safely protect the fuel tank 10, the above-described structure is a cause of weight and cost increase because the protective barrier composed of the side member 11 and the side seal 12 must be increased and the strength must be reinforced. When the impact energy is applied to the fuel tank 10 after the side chamber 12 and the side member 11 are deformed, there is a problem that the fuel tank 10 bursts and fuel flows out to increase the risk of fire.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 측면 충돌시 변형을 용이하게 하여 충격에너지를 흡수하고 파손에 의한 연료 누출을 방지하는 구조의 연료탱크를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and an object thereof is to provide a fuel tank having a structure for absorbing impact energy and preventing fuel leakage due to breakage by facilitating deformation during side impact.
상기한 목적을 달성하기 위하여 본 발명은The present invention to achieve the above object
연료를 저장하는 연료탱크에 있어서,In a fuel tank for storing fuel,
상기 연료탱크의 몸체 일부는 벨로우즈(Bellows)로 형성되며Part of the body of the fuel tank is formed of bellows (Bellows)
상기 연료탱크의 몸체 외부로 벨로우즈 형상의 외통체를 끼우고 그의 단부를 용접한 것을 특징으로 한다.A bellows-shaped outer cylinder is inserted into the outside of the body of the fuel tank, and an end thereof is welded.
도 1 은 본 발명에 의한 연료탱크를 나타내는 도면1 is a view showing a fuel tank according to the present invention
도 2 는 종래 연료탱크의 보호 구조를 설명하는 도면2 is a diagram illustrating a protection structure of a conventional fuel tank.
※ 도면 중 주요 부분에 대한 부호의 설명※ Explanation of the code for the main part of the drawing
1 : 연료탱크 2 : 몸체1: fuel tank 2: body
3 : 벨로우즈 4 : 외통체3: bellows 4: outer cylinder
5 : 용접부 6 : 공간5: welding part 6: space
7 : 브라켓트 8 : 벨로우즈7: Bracket 8: Bellows
이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.
도 1 은 본 발명에 의한 연료탱크의 단면도로 연료탱크(1)의 몸체(2) 일부는 벨로우즈(3,bellows)즉 주름으로 가공되어 있다.1 is a cross-sectional view of a fuel tank according to the present invention, in which a part of the body 2 of the fuel tank 1 is processed into bellows, that is, wrinkles.
그리고 벨로우즈 형상의 외통체(4)를 상기 몸체(2)에 끼워 그의 끝단부를 용접(5)한다.And the bellows-shaped outer cylinder 4 is inserted in the said body 2, and the edge part thereof is welded (5).
그리고 연료탱크 몸체(2)와 외통체(4)는 약간의 공간(6)을 두고 끼워 용접하는 것이 충격 흡수력을 높일 수 있다는 점에서 바람직하다.In addition, the fuel tank body 2 and the outer cylinder 4 are preferably welded with a small space 6 in that the shock absorbing force can be enhanced.
여기서 도면중 미설명 부호 7은 연료탱크를 장착하기 위한 브라켓트이다.Here, reference numeral 7 in the drawings is a bracket for mounting the fuel tank.
이에따라 측면 충돌이 발생하면 연료탱크 몸체(2)와 외통체(4)의 벨로우즈부(3)(8)가 쭈그러들면서 충격을 흡수하게 되므로써 연료탱크(1)내의 연료에 가해지는 충격을 흡수하게 되어 연료탱크(1)내의 연료에 가해지는 충격 에너지를 저감하여 화재 위험을 낮춘다.Accordingly, when a side collision occurs, the bellows portions 3 and 8 of the fuel tank body 2 and the outer cylinder 4 collapse and absorb the impact, thereby absorbing the impact applied to the fuel in the fuel tank 1. The risk of fire is reduced by reducing the impact energy applied to the fuel in the fuel tank 1.
이상과 같은 본 발명에 의한 연료탱크에 의하면 연료탱크의 몸체를 벨로우즈로 형성하고 또한 같은 벨로우즈 형상의 외통체를 끼워 용접하는 것에 의해서 측면 충돌시 용이한 변형에 의해 충격 에너지를 흡수하고 연료탱크가 찢어지는 등의 파손을 방지하여 연료 유출에 따른 화재 위험성을 저감하게 되는 효과가 있다.According to the fuel tank according to the present invention as described above, the body of the fuel tank is formed of bellows, and the same bellows-shaped outer cylinder is welded to absorb shock energy by easy deformation during side impact, and the fuel tank is torn. It is effective in reducing the risk of fire due to fuel leakage by preventing damage such as losing.
