본 발명인 연료탱크 보강구조는 캐니스터가 위치한 연료펌프 쪽의 연료 탱크에 보강패널을 구비하여 캐니스터의 타격으로부터 연료탱크의 훼손을 방지하는 구성이다.The fuel tank reinforcement structure of the present invention is provided with a reinforcement panel in the fuel tank on the fuel pump side where the canister is located to prevent damage to the fuel tank from the impact of the canister.

이와 같은 본 발명인 연료탱크 보강구조는 도 2에 도시된 바와 같이, 자동차의 후방에 구비하고 연료를 저장하는 연료탱크(100)와, 연료탱크(100)의 상면에 구비하고 연료탱크(100)에 저장된 연료를 펌핑하여 엔진계통에 공급하는 연료펌프(200)와, 연료탱크(100)의 후방에 함몰되게 형성한 지지면에 구비하고 연료탱크(100)에서 증발하는 연료가스를 포집하여 대기중으로 방출되는 것을 방지하는 캐니스터(300)와, 캐니스터(300)의 후방에 구비하고 스페어 타이어를 고정하는 타이어웰(400)을 포함하며, 연료펌프(200)는 연료탱크(100) 상면에 용접하여 부착한다.Such a fuel tank reinforcement structure of the present invention, as shown in Figure 2, provided in the rear of the vehicle and the fuel tank 100 for storing the fuel, the fuel tank 100 is provided on the upper surface of the fuel tank 100 A fuel pump 200 pumping the stored fuel and supplying it to the engine system, and a support surface formed to be recessed at the rear of the fuel tank 100 and collecting the fuel gas evaporated from the fuel tank 100 to be discharged into the atmosphere. And a tire well 400 provided at the rear of the canister 300 to fix the spare tire, and the fuel pump 200 is welded and attached to the upper surface of the fuel tank 100. .

여기서 상기 캐니스터(300)와 대응하는 연료펌프(200)와 연료탱크(100)의 용접부에는 후방 충돌시 캐니스터(300)의 타격에 의해 연료탱크(100)가 하향 변형되는데, 이 연료탱크(100)의 하향 변형력을 유도하는 한편, 연료펌프(200)와 연료탱크(100) 용접부까지 변형력이 전달되지 않도록 차단하여 연료탱크(100)의 찢어지는 현상을 방지하는 보강부재(500)를 구비한다.In this case, the fuel tank 100 is deformed downward by the blow of the canister 300 during the rear collision to the weld portion of the fuel pump 200 and the fuel tank 100 corresponding to the canister 300, and the fuel tank 100 While inducing a downward deformation force of the fuel pump 200 and the fuel tank 100 is provided with a reinforcing member 500 to prevent the deformation force is transmitted to the welding portion to prevent the tearing of the fuel tank 100.

즉, 차량의 후방 충돌시 발생하는 충격력이 타이어웰(400)로부터 캐니스터(300)에 전달되고, 이 충격력에 의해 캐니스터(300)는 연료탱크(100)의 후방을 타격하는데, 이때 캐니스터(300)의 타격으로 인해 연료탱크(100)의 후방 패널이 점차 하향 변형하면서 연료펌프(200)와 연료탱크(100)의 용접부까지 전달되고, 이에 연료펌프의 지지 강성에 의해 연료탱크(100) 얇은 패널의 찢김 현상이 발생한다.That is, the impact force generated during the rear collision of the vehicle is transmitted from the tire well 400 to the canister 300, and the canister 300 strikes the rear of the fuel tank 100 by the impact force, wherein the canister 300 As the rear panel of the fuel tank 100 is gradually deformed due to the hit of the fuel tank 100, the fuel panel 200 is transferred to the welded portion of the fuel pump 200 and the fuel tank 100, and thus, the support panel rigidity of the fuel tank 100 makes the thin panel of the fuel tank 100 thin. Tearing occurs.

이를 방지하기 위해 연료펌프(200)와 연료탱크(100)의 용접부 중 연료탱크(100) 패널의 지지 강성을 증대시키기 위해 연료탱크(100)의 내측에 보강부재(500)를 용접하여 부착함으로써 후방 충돌시 캐니스터(300)의 충격력에 의한 연료탱크(100)의 하향 변형력을 보강부재(500)까지 이루어지도록 유도하는 한편, 연료탱크(100)의 하향 변형력이 연료펌프(200)와 연료탱크(100) 용접부까지 전달되는 것을 차단한다. 이에 따라 연료탱크(100)의 찢김 현상을 방지한다.In order to prevent this, the reinforcing member 500 is welded and attached to the inside of the fuel tank 100 to increase the support rigidity of the panel of the fuel tank 100 among the weld parts of the fuel pump 200 and the fuel tank 100. During the collision, the downward deformation force of the fuel tank 100 by the impact force of the canister 300 is induced to the reinforcing member 500, while the downward deformation force of the fuel tank 100 is the fuel pump 200 and the fuel tank 100. ) It blocks the transmission to the welding part. Accordingly, tearing of the fuel tank 100 is prevented.

이와 같은 보강부재(500)는 도 3에 도시된 바와 같이, 연료탱크(100)의 내측패널에 용접하여 부착하고, 1.2T로 이루어진다.As shown in FIG. 3, the reinforcing member 500 is attached to the inner panel of the fuel tank 100 by welding, and is made of 1.2T.

그리고 캐니스터(300) 쪽의 보강부재(500) 단부는 하향 절곡 형성하는 곡면부(510)를 형성하며, 이는 캐니스터(300) 타격시 보강부재(500) 단부를 따라 연료탱크(100) 패널이 곡선으로 변형되면서 연료탱크(100)의 훼손을 방지한다.The end of the reinforcing member 500 on the side of the canister 300 forms a curved portion 510 which is bent downward, and the fuel tank 100 panel curves along the end of the reinforcing member 500 when the canister 300 is hit. While being deformed to prevent damage to the fuel tank (100).

한편, 상기 보강부재(500)는 연료펌프(200)와 연료탱크(100)의 용접부 보다 캐니스터(300)쪽으로 앞에 위치하도록 연장 형성하며, 이는 캐니스터(300)로부터 작은 충격이라도 연료펌프(200)와 연료탱크(100)의 용접부에 전달되지 않도록 미리 차단할 수 있다.On the other hand, the reinforcing member 500 is formed to extend in front of the canister 300 than the weld portion of the fuel pump 200 and the fuel tank 100, which is a small impact from the canister 300 and the fuel pump 200 The fuel tank 100 may be blocked in advance so as not to be delivered to the welded portion of the fuel tank 100.

한편, 캐니스터(300)는 브라켓(600)에 의해 연료탱크(100)에 고정하며, 이 브라켓(600)은 0.6T로 이루어진다.On the other hand, the canister 300 is fixed to the fuel tank 100 by a bracket 600, the bracket 600 is made of 0.6T.

즉, 보강부재(500)와 함께 브라켓(600)은 캐니스터(300)에 전달되는 충격력을 흡수하여 연료탱크(100)의 변형을 방지할 수 있다.That is, the bracket 600 together with the reinforcing member 500 may absorb the impact force transmitted to the canister 300 to prevent deformation of the fuel tank 100.

이와 같은 구성을 가지는 연료탱크 보강구조는 후방 충돌시 타이어웰(400)에 의해 캐니스터(300)가 전방으로 이동하면서 연료탱크(100) 후방을 타격하는데, 이때 브라켓(600)에 의해 1차 충격력이 흡수되면서 충격력을 감소하고, 2차로 연료탱크(100)를 타격하면서 연료탱크(100)의 후방이 하향 변형한다.The fuel tank reinforcement structure having such a configuration hits the rear of the fuel tank 100 while the canister 300 moves forward by the tire well 400 during the rear collision, and the first impact force is caused by the bracket 600. The impact force is reduced while being absorbed, and the rear of the fuel tank 100 is downwardly deformed while hitting the fuel tank 100 in a second manner.

이때, 연료탱크(100)의 내측에 부착된 보강부재(500)가 연료탱크(100)의 강성을 보강함으로써 연료탱크(100)의 변형이 연료펌프(200) 용접부까지 전달되는 것을 차단하여 연료탱크의 찢김 현상 등의 파손을 방지한다.At this time, the reinforcement member 500 attached to the inner side of the fuel tank 100 reinforces the rigidity of the fuel tank 100, thereby preventing the deformation of the fuel tank 100 from being transmitted to the fuel pump 200 to weld the fuel tank. To prevent breakage and tearing.
