Description

  The present invention relates to a fuel box structure that holds the tip of a fuel supply pipe that guides fuel to a fuel tank of a vehicle.

  The tip of a fuel supply pipe that guides fuel to a fuel tank of a vehicle is generally held by a fuel box structure (see Patent Document 1). The fuel box structure of Patent Document 1 includes a fuel box that surrounds the front end of the fuel supply pipe, and a cylindrical elastic body that extends from the fuel box to the inside of the vehicle. The cylindrical elastic body includes a pair of lip rings protruding from the outer peripheral surface of the elastic body. The inner panel of the vehicle is sandwiched between a pair of lip rings. As a result, a seal structure is formed between the inner panel and the fuel box.

International Publication No. WO2012 / 049956

  According to the technique of Patent Document 1, each of the pair of lip rings is a thin elastic film body, and thus is easily bent when the fuel box structure is incorporated into a vehicle. One of the pair of lip rings appears on the outer surface of the inner panel, while the other of the pair of lip rings appears on the inner surface of the inner panel, so an operator who incorporates the fuel box structure into the vehicle It is very difficult to visually confirm whether each lip ring is bent or not. Therefore, the operator needs to assemble the fuel box structure very carefully on the vehicle.

  An object of the present invention is to provide a fuel box structure that has a high sealing property and enables an easy assembly operation of the fuel box structure to a vehicle.

  A fuel box structure according to an aspect of the present invention includes a fuel refueling pipe that guides fuel to a fuel tank of a vehicle, with an end between an outer panel that forms a side surface of the vehicle and an inner panel that is disposed on the inner side of the outer panel. Hold on. The fuel box structure includes a fuel box having a bottom plate portion formed with a through-hole through which the tip of the fuel supply pipe passes, an elastic first lip extending from the bottom plate portion toward the inner panel, and the first A sealing body having an elastic second lip extending from one lip toward the inner panel.

  According to said structure, the front-end | tip of a fuel supply pipe is inserted in the through-hole formed in the baseplate part of a fuel box. Therefore, the fuel box can hold the tip of the fuel supply pipe. Since the first lip extends from the bottom plate portion toward the inner panel, a seal structure is formed between the first lip and the inner panel. Since the second lip also extends towards the inner panel, an additional sealing structure is formed between the second lip and the inner panel. Therefore, the fuel box structure can have high sealing performance. Since the second lip extends from the first lip, the seal body can have sufficient rigidity to prevent bending. Therefore, the operator who assembles the fuel box structure on the vehicle does not have to worry about bending of the seal body. As a result, the operator can easily assemble the fuel box structure to the vehicle.

  With regard to the above configuration, the first lip includes a first base end edge connected to the bottom plate portion, and a first front end edge abutting against the inner panel, and the first lip extends from the first front end edge to the first end edge. A hollow first frustum that narrows toward one base edge may be formed. The first tip edge may surround an insertion hole formed in the inner panel for insertion of the fuel supply pipe.

  According to the above configuration, the first lip forms a hollow first frustum that narrows from the first tip edge toward the first base edge, so that the first lip bends in a direction toward the central axis of the first frustum. Is less likely to occur at the first tip edge. Since the elastic deformation direction of the first lip is controlled by the shape of the first frustum, the operator does not have to worry about bending of the first lip in an undesired direction. As a result, the operator can easily assemble the fuel box structure to the vehicle.

  With respect to the above configuration, the first frustum may include an inner peripheral surface and an outer peripheral surface surrounding the inner peripheral surface. The second lip contacts the inner panel so as to surround the insertion hole and a second base end edge connected to the inner peripheral surface between the first base end edge and the first front end edge. And a second tip edge.

  According to said structure, since the 2nd base end edge of a 2nd lip is connected to an internal peripheral surface between a 1st base end edge and a 1st front end edge, a 1st lip prevents bending. Can have sufficient rigidity. Therefore, the operator who assembles the fuel box structure on the vehicle does not have to worry about bending of the seal body. As a result, the operator can easily assemble the fuel box structure to the vehicle. Since the second tip edge of the second lip is brought into contact with the inner panel so as to surround the insertion hole, the insertion hole is separated from the inner panel by a seal structure formed by the first lip, the second lip and the inner panel. It is separated from the space between the outer panels.

  In the above configuration, the second lip may form a hollow second frustum that narrows from the second base end edge toward the second tip end edge.

  According to the above configuration, the second lip forms a hollow second frustum that narrows from the second base end edge toward the second front end edge. Therefore, when the seal body is pressed against the inner panel, The first lip and the second lip are elastically deformed such that the edge is away from the first tip edge. As a result, a wide seal area is formed between the first tip edge and the second tip edge. Therefore, the fuel box structure can have high sealing performance.

  With respect to the above configuration, the second lip may protrude at a right angle to the bus bar of the first frustum.

  According to said structure, since a 2nd lip protrudes at right angles with respect to the bus-line of a 1st frustum, the 1st lip is an external force which acts in the direction which goes to an internal peripheral surface from the outer peripheral surface of a 1st frustum. On the other hand, it can have high rigidity.

  With respect to the above configuration, the first frustum may include an inner peripheral surface and an outer peripheral surface surrounding the inner peripheral surface. The second lip contacts the inner panel so as to surround the first base edge and the second base edge connected to the outer peripheral surface between the first base edge and the first front edge. And a second tip edge to be in contact with.

  According to said structure, since the 2nd base end edge of a 2nd lip is connected to an outer peripheral surface between a 1st base end edge and a 1st front end edge, in order to prevent a 1st lip from bending. It can have sufficient rigidity. Therefore, the operator who assembles the fuel box structure on the vehicle does not have to worry about bending of the seal body. As a result, the operator can easily assemble the fuel box structure to the vehicle. Since the second tip edge of the second lip is abutted against the inner panel so as to surround the first tip edge of the first lip, an additional seal is provided so as to surround the seal region formed by the first tip edge. A region is formed. Therefore, the fuel box structure can have high sealing performance.

  With regard to the above configuration, the first frustum may be a truncated cone.

  According to said structure, since the said 1st frustum is a truncated cone, a 1st front-end | tip edge will be pressed on an inner panel with a substantially equal force. Therefore, a part with extremely low sealing performance is unlikely to occur in the seal body.

  With regard to the above configuration, the fuel box structure includes a peripheral wall portion that extends from the bottom plate portion toward the outer panel and surrounds the tip of the fuel supply pipe, and a lid that closes an opening formed by the peripheral wall portion. Further, it may be provided. The peripheral wall portion may include a hollow bulging portion that bulges into a space between the inner panel and the outer panel. The lid body is disposed in the bulging portion and has an arm having a base end portion rotatably connected to the bulging portion; a lid plate connected to the arm and closing the opening portion; , May be included. When the arm is rotated around the base end, the lid plate may move from a closed position that closes the opening to an open position that opens the opening.

  According to said structure, since a surrounding wall part surrounds the front-end | tip of a fuel supply pipe | tube, the fuel which leaked from the fuel supply pipe | tube, or the fuel which failed to flow into a fuel supply pipe | tube is received by a surrounding wall part. Since the lid closes the opening formed by the peripheral wall, the tip of the fuel supply pipe is not unnecessarily exposed. Since the peripheral wall portion includes a hollow bulging portion that bulges into the space between the inner panel and the outer panel, the base end portion of the arm connecting the lid plate of the lid portion and the peripheral wall portion is accommodated in the bulging portion. Is done. Since the lid is moved from the closed position to the open position in accordance with the rotation of the arm around the base end, the user can expose the tip of the fuel supply pipe. Thereafter, the user may connect a hose extending from the fuel supply device to the fuel supply pipe and supply the fuel to the vehicle.

  The operator may push the bulging portion into the space between the inner panel and the outer panel before other portions. In this case, since the bottom plate portion is inclined from the inner panel, a part of the seal body is pressed against the inner panel before the other parts. As described above, since the sealing body has high rigidity, even if a part of the sealing body is pressed against the inner panel before the other part, an undesirable bending is unlikely to occur in the sealing body. Therefore, the operator can easily assemble the fuel box structure to the vehicle.

  The fuel box structure described above has a high sealing property and can be easily assembled to a vehicle.

<First Embodiment>
Bending of the sealing body when the fuel box structure is incorporated in the vehicle makes the vehicle assembly process very inefficient. The present inventors have developed a fuel box structure including a sealing body having a shape that is not easily bent. In the first embodiment, an exemplary fuel box structure is described.

  FIG. 1 is a schematic cross-sectional view of a fuel box structure 100 according to the first embodiment. With reference to FIG. 1, a fuel box structure 100 will be described.

  The fuel box structure 100 is disposed between the outer panel OPL that forms the side surface of the vehicle and the inner panel IPL that is disposed on the inner side of the outer panel OPL. The fuel box structure 100 holds the tip FPT of the fuel supply pipe FFP between the outer panel OPL and the inner panel IPL. The tip FPT of the fuel supply pipe FFP is exposed from an opening area OPA formed in the outer panel OPL. The fuel supplier can connect a hose (not shown) extending from a fuel supply device (not shown) to the tip FPT of the fuel supply pipe FFP and pour fuel into the fuel supply pipe FFP. The fuel supply pipe FFP guides fuel to the fuel tank of the vehicle.

  The fuel box structure 100 includes a fuel box 200 and a seal body 300. The seal body 300 is formed integrally with the fuel box 200. The seal body 300 is entirely formed of an elastic resin that can be elastically deformed. The fuel box 200 is substantially entirely formed of a hard resin. The fuel box structure 100 may be formed by a two-color molding technique.

  The fuel box 200 includes a bottom plate part 210, a peripheral wall part 220, and a flange 230. The bottom plate portion 210 is disposed closer to the inner panel IPL than the outer panel OPL. The peripheral wall portion 220 is a cylindrical body that extends from the bottom plate portion 210 toward the outer panel OPL. The peripheral wall portion 220 includes an opening edge 221 that forms an outline of the opening 222 that opens toward the opening region OPA of the outer panel OPL. The refueling person can insert a hose extending from the refueling device into the opening area OPA and the opening 222 and connect it to the tip FPT of the fuel refueling pipe FFP. The flange 230 is an annular portion that protrudes outward from the opening edge 221 (that is, in a direction opposite to the opening 222). The flange 230 is in contact with the concave wall portion RWL of the outer panel OPL that forms the opening area OPA.

  The bottom plate portion 210 includes a hard portion 211 formed from the above-described hard resin and an elastic portion 212 formed from the above-described elastic resin. The joining between the elastic part 212 and the hard part 211 depends on the two-color molding technique described above.

  The elastic part 212 includes an inner edge 213 that forms the outline of the through hole through which the tip FPT of the fuel supply pipe FFP passes. The inner edge 213 contacts the outer peripheral surface of the tip FPT of the fuel supply pipe FFP. As a result, a seal structure is formed between the inner edge 213 of the elastic portion 212 and the outer peripheral surface of the tip FPT of the fuel supply pipe FFP. The fuel leaking from the tip FPT of the fuel supply pipe FFP and the fuel that has failed to flow into the tip FPT of the fuel supply pipe FFP are blocked by the seal structure and can remain in the space surrounded by the peripheral wall 220.

  Seal body 300 protrudes from bottom plate portion 210 toward inner panel IPL. The tip of the seal body 300 is pressed against the inner panel IPL to form another seal structure. The seal structure prevents small pieces or liquid splashed by the wheel from entering the space between the outer panel OPL and the inner panel IPL.

  FIG. 2 is a schematic cross-sectional view of the seal body 300. The seal body 300 will be described with reference to FIG.

  The seal body 300 includes a first lip 310 and a second lip 320. Both the first lip 310 and the second lip 320 are made of the elastic resin described above. The first lip 310 includes a first proximal edge 311 and a first distal edge 312. The first base end edge 311 is connected to the bottom plate part 210. The first lip 310 extends from the bottom plate portion 210 toward the inner panel IPL. The first tip edge 312 is pressed against the inner panel IPL.

  The first lip 310 forms a hollow truncated cone that narrows from the first distal edge 312 to the first proximal edge 311. Accordingly, the first lip 310 is easily deformed such that the first tip edge 312 is separated from the center axis of the truncated cone, while the first tip edge 312 is not easily bent in the direction toward the center axis of the truncated cone. As a result, the operator can press the seal body 300 against the inner panel IPL without worrying about the undesirable bending of the first lip 310. With respect to this embodiment, the first frustum is exemplified by a hollow truncated cone formed by the first lip 310.

  The first lip 310 includes an inner peripheral surface 313 and an outer peripheral surface 314 surrounding the inner peripheral surface 313. The first tip edge 312 surrounds an insertion hole formed in the inner panel IPL for insertion of the fuel supply pipe. The second lip 320 extends from the inner peripheral surface 313 toward the inner panel IPL.

  The second lip 320 includes a second proximal edge 321 and a second distal edge 322. The second base end edge 321 is connected to the inner peripheral surface 313 between the first base end edge 311 and the first front end edge 312. The second lip 320 protrudes at a substantially right angle to the generatrix of the truncated cone formed by the first lip 310. Accordingly, the second lip 320 can provide the first lip 310 with sufficient rigidity to prevent the first lip 310 from bending in an undesirable direction. As a result, the operator can press the seal body 300 against the inner panel IPL without worrying about the undesirable bending of the first lip 310.

  The second lip 320 forms a hollow truncated cone that narrows from the second base edge 321 toward the second tip edge 322. The second tip edge 322 is pressed against the inner panel IPL so as to surround an insertion hole formed in the inner panel IPL for insertion of the fuel supply pipe in a substantially circular region surrounded by the first tip edge 312. It is done. With respect to this embodiment, the second frustum is exemplified by a hollow truncated cone formed by the second lip 320.

  The second lip 320 includes an inner peripheral surface 323 and an outer peripheral surface 324 surrounding the inner peripheral surface 323. When the seal body 300 is pressed against the inner panel IPL, the outer peripheral surface 324 of the second lip 320 and the inner peripheral surface of the first lip 310 that forms a region between the first tip edge 312 and the second base end edge 321. A part of 313 makes surface contact with the inner panel IPL. Therefore, the seal body 300 can be in close contact with the inner panel IPL in a wide area and form a seal structure having high sealing performance.

The second lip 320A includes a facing surface 323A and a sealing surface 324A. The facing surface 323 </ b> A faces the inner peripheral surface 313 of the first lip 310 and / or the bottom plate portion 210 of the fuel box 200. The seal surface 324A is located on the opposite side of the facing surface 323A and is in contact with the inner panel IPL. The seal surface 324A is in surface contact with the inner panel IPL so as to surround an insertion hole formed in the inner panel IPL for insertion of the fuel supply pipe. As a result, the second lip 320A can prevent the first lip 310 from bending so that the first tip edge 312 faces the center line CTL.
