본 발명은 차량용 스페어타이어의 밀림방지장치에 관한 것으로, 보다 상세하게는 서브프레임으로 스페어타이어를 감싸 차량의 후방 충돌시 스페어타이어가 연료탱크 쪽으로 이동되지 않도록 된 차량용 스페어타이어 밀림방지장치에 관한 것이다.The present invention relates to a skid prevention device of a spare tire for a vehicle, and more particularly, to a spare tire skid prevention device for a vehicle such that the spare tire is not moved to the fuel tank during the rear collision of the vehicle by wrapping the spare tire in a subframe.

일반적으로 자동차는 차체와 샤시 및 엔진으로 구성되며, 차체는 또한 다양한 프레임 및 패널로 이루어지는데, 이와 같은 패널들로는 전방패널과 후방패널, 루프패널 및 하부차체를 형성한 플로어 패널들이 서로 용접 접합되는데, 이중 플로어패널은 자동차의 실내의 하부를 형성하며 통상적으로 전방시트가 장착되는 전방플로어패널과, 이 전방플로어패널의 후방부에 접하고 후방시트가 장착됨과 더불어 또한 트렁크룸의 바닥면을 형성하는 후방플로어패널로 구분된다.In general, an automobile is composed of a car body, a chassis and an engine, and the car body also includes various frames and panels, which are welded to each other by floor panels forming the front panel and the rear panel, the roof panel and the lower body. The double floor panel forms the lower part of the interior of the vehicle and is usually the front floor panel to which the front seat is mounted, and the rear floor which is in contact with the rear part of the front floor panel and is equipped with the rear seat and also forms the bottom surface of the trunk room. It is divided into panels.

여기서, 상기 후방플로어패널(1)은 도 1에 도시된 바와 같이 전방부위에는 후방시트설치부(1a)가 형성되면서 그 후방부위에는 트렁크룸의 바닥을 형성하면서 스페어타이어(2)가 수용·적재될 수 있도록 함몰된 적재함(5)이 형성되는 한편, 상기 후방플로어패널(1)의 하부부위로는 후방시트설치부(1a)부위로 브라켓트와 스트랩을 매개로 연료탱크(3)가 장착된다.Here, the rear floor panel 1 has a rear seat installation portion 1a formed at the front portion as shown in FIG. 1 while the spare tire 2 is accommodated and loaded while forming the bottom of the trunk room at the rear portion thereof. A loading box 5 recessed to be formed is formed, while a fuel tank 3 is mounted to a lower portion of the rear floor panel 1 through a bracket and a strap to a rear seat installation portion 1a.

또한, 상기 스페어타이어웰(2)와 연료탱크(3)사이에는 양쪽 차륜을 연결하면서 차폭을 가로지르는 서브프레임(4)이 구비되어진다.In addition, between the spare tire well 2 and the fuel tank 3 is provided with a subframe 4 crossing the vehicle width while connecting both wheels.

그러나, 이와 같이 후방플로어패널(1)에서 지면쪽으로 함몰된 적재함(5)에 수용된 스페어타이어(2)와 상기 후방플로어패널(1)의 하부부위로 장착된 연료탱크(3) 및 스페어타이어(2)와 연료탱크(3)사이에 위치된 서브프레임(4)이 서로 동일 선상으로 위치되면 후방 충돌시 매우 위험한 상황을 야기 시킬 수 있는데 즉, 도 2에 도시된 바와 같이 충돌물체(O)에 의한 후방 충돌로 인해 파손되면서 밀려드는 범퍼(B)에 의한 충격력(F)이 스페어타이어(2)가 수용된 적재함(5)으로 전달되고 이에 따라, 상기 스페어타이어(2)가 전방으로 이동되면서 서브프레임(4)과 연료탱크(3)를 타격해 손상을 주는 문제가 있게 된다.However, the spare tire 2 accommodated in the loading box 5 recessed toward the ground in the rear floor panel 1 and the fuel tank 3 and the spare tire 2 mounted to the lower part of the rear floor panel 1, respectively. ) And the subframe 4 positioned between the fuel tank 3 on the same line may cause a very dangerous situation in the rear collision, that is, due to the collision object O as shown in FIG. The impact force F caused by the bumper B, which is damaged due to the rear collision, is transmitted to the storage box 5 in which the spare tire 2 is accommodated. As a result, the spare tire 2 is moved forward and the subframe ( 4) and the fuel tank (3) is a problem that damages.

또한, 이와 같이 연료탱크(3)가 타격 되면 연료탱크(3)가 변형되거나 파열됨으로써 연료탱크내의 연료가 외부로 유출되고 이로 인해, 상기 연료탱크(3)로부터 연료가 유출되어 화재가 발생될 수 있어 운전자 및 탑승자가 심각한 위험에 처해지는 문제점이 있었다.In addition, when the fuel tank 3 is hit in this way, the fuel tank 3 is deformed or ruptured, so that the fuel in the fuel tank is leaked to the outside, whereby the fuel may be leaked from the fuel tank 3 to cause a fire. There was a problem that the driver and passengers are in serious danger.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 후방 충돌시 연료탱크와 동일 선상으로 위치되는 스페어타이어 밀림을 서브프레임을 매개로 차단해 스페어타이어에 의한 연료탱크의 변형과 파손을 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-mentioned problem, and prevents deformation and breakage of the fuel tank by the spare tire by blocking the spare tire jungle positioned in the same line as the fuel tank during the rear collision through the subframe. The purpose is.

상기와 같은 목적을 달성하기 위한 본 발명은, 후방플로어패널의 전방부위의 저면부위로 브라켓트와 스트랩을 매개로 연료탱크가 장착되면서 그 후방부위를 이루는 트렁크룸내로 스페어타이어가 수용·적재될 수 있도록 저면으로 돌출된 적재함이 형성되되, 이 적재함의 돌출부위는 양쪽 후륜을 연결하면서 차폭을 가로지르는 서브프레임의 수용홈에 의해 감싸여진 것을 특징으로 한다.The present invention for achieving the above object, while the fuel tank is mounted to the bottom of the front portion of the rear floor panel via the bracket and strap so that the spare tire can be accommodated and loaded into the trunk room forming the rear portion. A loading bin is formed to protrude to the bottom, and the protrusion of the loading bin is surrounded by the receiving groove of the subframe crossing the vehicle width while connecting both rear wheels.

이하 본 발명의 작동을 첨부된 도면을 참고로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 후방플로어패널(1)의 후방시트설치부(1a)가 장착되는 하부부위로 장착된 연료탱크(3)에 간격을 두고 양쪽 차륜을 연결하면서 차폭을 가로지르는 서브프레임(4)이 트렁크 룸으로부터 외부로 노출된 적재함(5)을 감싸게 되므로 이에 따라, 상기 적재함(5)이 서브프레임(4)에 의해 이중구조를 갖게 되어 그 강성이 더욱 강화되어진다.According to the present invention, the subframe 4 crossing the vehicle width while connecting both wheels at intervals to the fuel tank 3 mounted to the lower portion on which the rear seat installation portion 1a of the rear floor panel 1 is mounted is trunked. Since the stack 5 is exposed to the outside from the room, the stack 5 has a double structure by the subframe 4, thereby further strengthening its rigidity.

또한, 본 발명은 서브프레임(4)이 적재함(5)을 감싸게 되므로 서브프레임(4)과 적재함(5)을 따로 형성했던데 비해 공간상 여유간격을 확보하게 되고 이에 따라, 상기 서브프레임(4)과 연료탱크(3)사이의 여유 간격을 늘려 충격 흡수용 공간을 더욱 확보 할 수 있게 된다.In addition, in the present invention, since the subframe 4 surrounds the loading box 5, the subframe 4 and the loading box 5 are separately formed, thereby securing a clearance in space. Accordingly, the subframe 4 By increasing the clearance between the fuel tank and the fuel tank (3) it is possible to secure more space for shock absorption.

그리고, 차량의 후방충돌시 외부 물체(O)에 의해 충격력(F)을 받은 범퍼(B)로부터 가해지는 스페어타이어(2)쪽으로 가해지는 충격력(F)은 도 4에 도시된 바와 같이, 후방플로어패널(1)을 변형시키면서 스페어타이어(2)가 적재된 적재함(5)에 충격을 가하게 되는데 이때, 상기 충격력(F)은 적재함(5)을 감싼 서브프레임(4)을 변형시키면서 흡수되어 크게 약화되면서 만약, 충격력(F)이 남아있게 되면 적재함(5)을 변형시키게 된다.Then, the impact force (F) applied to the spare tire (2) applied from the bumper (B) subjected to the impact force (F) by the external object (O) during the rear collision of the vehicle, as shown in Figure 4, the rear floor While the panel 1 is deformed, an impact is applied to the loading box 5 in which the spare tire 2 is loaded. At this time, the impact force F is absorbed while deforming the subframe 4 surrounding the loading box 5 and is greatly weakened. While, if the impact force (F) is left to deform the loading box (5).

이어, 상기 적재함(5)의 변형에 따라 수용된 스페어타이어(2)가 연료탱크(3)쪽으로 밀리려는 힘을 받지만 후방플로어패널(1)의 저면에서 부시(4')를 매개로 고정되어 차폭을 가로지르는 서브프레임(4)에 의해 다시 저지 당하게 되고 이에 따라, 상기 스페어타이어(2)가 연료탱크(3)쪽으로 밀리는 것을 최대한 억제해 연료탱크(3)의 손상이나 파손의 위험이 크게 저하하게 된다.Subsequently, the spare tire 2 received according to the deformation of the loading box 5 receives a force to push toward the fuel tank 3, but is fixed through the bush 4 ′ at the bottom of the rear floor panel 1 through the bush 4 ′. It is again blocked by the intersecting subframe (4), thereby restraining the spare tire (2) from being pushed toward the fuel tank (3) as much as possible to greatly reduce the risk of damage or breakage of the fuel tank (3) .

이상 설명한 바와 같이 본 발명에 의하면, 스페어타이어를 수용하는 적재함을 서브프레임이 감싸게 되어 차량의 후방 범퍼로부터 가해지는 큰 충격을 다중적으로 흡수해 약화시키면서 스페어타이어의 연료탱크쪽으로 이동을 저지해 동일선상에 위치되는 연료탱크의 손상이나 파손을 거의 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the subframe surrounds the storage box accommodating the spare tire, thereby preventing the movement toward the fuel tank of the spare tire while absorbing and weakening the large impact applied from the rear bumper of the vehicle multiplely. There is an effect that can be almost prevented damage or breakage of the fuel tank located in the.
