Description

  The present invention opens from the inside of the vehicle body toward the inside of the recess formed on the outer surface of the vehicle body, and is pivotally supported by the vehicle body and a fuel inlet that communicates with a vehicle-mounted fuel tank. The present invention relates to a fuel injection device in a vehicle for preventing a lid from being largely displaced by an external force even if an external force is applied to the lid when the lid is provided with an openable / closable opening. .

  Conventionally, there is a fuel injection apparatus disclosed in Patent Document 1 below. According to this publication, the fuel injection device includes a fuel injection port that opens from the inside of the vehicle body into a recess formed in the outer surface of the vehicle body, a cap that allows the fuel injection port to be opened and closed, The lid is pivotally supported by the vehicle body so as to be pivotable about the pivot shaft, and the opening of the recess can be opened and closed by opening and closing the pivot. The lid is provided on the lid. A stopper is provided that abuts a part of the recess when the opening of the recess is fully opened, and prevents further opening rotation of the lid.

  Further, there is a conventional fuel injection apparatus disclosed in Patent Document 2 below. According to this publication, there is no description of the stopper in Patent Document 1, but the movement of the cap in the axial direction of the pivot shaft provided on the lid referred to in Patent Document 1 toward the lid side. Thus, a cap temporary placement portion is provided that allows the cap to be temporarily placed on the lid.

  When the fuel injection device of Patent Documents 1 and 2 is used to inject fuel through the fuel injection port using an injection gun or the like, first, the lid that closes the opening of the recess is used. Rotate to open. When the opening of the recess is fully opened by this opening rotation, it is prevented that the lid is unnecessarily opened and rotated by the stopper coming into contact with a part of the recess.

  Next, with the lid fully opening the recess, the cap closing the fuel inlet is gripped, and the cap is removed from the fuel inlet to open the fuel inlet. At this time, the operator holding the cap moves the cap from the upper side to the lower side so as to move toward the temporary cap placement unit, and places the cap on the temporary placement unit.

  This frees the operator from continuing to hold the cap. For this reason, after that, the operation of injecting fuel through the fuel injection port using the injection gun or the like can be performed smoothly and easily for the operator.

  Then, after injecting the desired fuel, the cap is taken out from the temporary cap placement section by the reverse procedure to the above, and the fuel injection port is closed by this cap. Next, the lid is closed and turned to fully close the opening of the recess. Then, the injection operation is finished.

JP-A-9-226390 JP-A-8-188058

  By the way, the cap removed from the fuel injection port is moved to the lid side as described above in a state where the opening of the recess is fully opened during the above-described injection operation, and the cap temporary placement portion of this lid is moved. In the temporary placement, the operator may unnecessarily apply a large external force (including a component force) toward the cap temporary placement portion in the axial direction of the pivot shaft. Also, in this case, the injection gun is inadvertently collided with the lid, or an operator places a hand on the lid. There is a risk that an unnecessarily large external force (including a component force) is applied in the direction.

  Here, in order to improve the appearance of the vehicle body, the lid is usually installed as follows on the vehicle body. That is, when the lid is fully closed, the lid is inserted into the opening so that the outer surfaces of the outer plate and the lid are flush with each other, and the opening edge of the opening The gap between the portion and the outer edge of the lid is set to be narrow.

  For this reason, as described above, when a certain external force is applied unnecessarily large in the axial direction of the pivot shaft with respect to the lid, and the lid is displaced even a little in the axial direction of the pivot shaft, A part of the outer edge part of the lid may come into pressure contact with part of the opening edge part of the opening of the recess, and there is a possibility that the mutual pressure contact part may be damaged.

  Therefore, even when some external force is applied to the lid from the operator during the injection operation, the rigidity of the pivot support is increased, for example, by increasing the plate thickness of the pivot support so that the lid is not greatly displaced, It may be possible to reinforce the pivotal support by providing a separate reinforcing material. However, this is not preferable because the mass of the fuel injection device may be increased or the configuration may be complicated.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to provide a fuel inlet opening from the inside of the vehicle body toward the inside of a recess formed on the outer surface of the vehicle body, and a pivot on the vehicle body. In a fuel injection device in a vehicle provided with a lid that is supported and that can open and close the opening of the recess by opening / closing rotation, when performing fuel injection through the fuel injection port, some external force is applied to the lid. The outer edge of the lid is prevented from being pressed against the opening edge of the opening of the recess, and the occurrence of scratches due to the pressure contact is prevented, and This is to prevent the occurrence of scratches with a light and simple structure.

The invention according to claim 1 includes a fuel injection port 13 that opens from the inside of the vehicle body 2 toward a recess 10 formed in the outer surface of the vehicle body 2, and a pivot shaft 40 of the pivotal support 17 on the vehicle body 2. The lid 19 is pivotally supported and can be opened and closed by opening and closing rotations A and B. The lid 19 can be opened and closed. The lid 19 is provided with an opening rotation A. When the opening 18 of the place 10 is fully opened (solid line in FIGS. 1 and 2), a stopper 49 that abuts a part of the recess 10 and prevents further opening rotation A of the lid 19 is provided. In a fuel injection device in a vehicle,
With the lid 19 fully opening the opening 18 of the recess 10, when the stopper 49 is displaced together with the lid 19 in the axial direction C of the pivot shaft 40, this displacement is restricted. The fuel injection device for a vehicle is characterized in that a support portion 54 with which a stopper 49 abuts is formed in the recess 10.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

The invention of claim 1 is supported by a fuel injection port that opens from the inner side of the vehicle body toward a recess formed in the outer surface of the vehicle body, and is pivotally supported by the vehicle body so as to be rotatable about a pivot shaft of a pivot tool. A lid that can open and close the opening of the recess by the opening and closing rotation, and provided on the lid, and when the opening of the recess is fully opened by the opening and turning of the lid, a part of the recess is contacted. In contact with the fuel injection device in the vehicle provided with a stopper that prevents further opening rotation of the lid,
When the lid is fully open in the recess, when the stopper is displaced together with the lid in the axial direction of the pivot shaft, the support portion that abuts the stopper to restrict the displacement. Is formed in the above-mentioned recess, and the following effects are produced.

  That is, during an injection operation for injecting fuel through the fuel injection port, an operator can support the pivot shaft of the pivot tool with respect to the lid in a state where the opening of the recess is fully opened. It is assumed that some external force is applied unnecessarily large in the axial direction. Then, the lid tends to be displaced relative to the vehicle body in the axial direction of the pivot shaft together with the stopper by the external force. However, in this case, according to the invention, the stopper is brought into contact with the support portion to restrict the displacement.

  Therefore, as described above, even if some external force is applied to the lid during the injection operation, the outer edge of the lid is prevented from being pressed against the opening edge of the opening of the recess. The occurrence of scratches is prevented.

  Moreover, the prevention which the said damage | occurrence | occurrence generation | occurrence | production uses the stopper which prevents the further opening rotation of the lid when the opening of the said recess is fully opened. Therefore, the occurrence of the damage can be prevented without increasing the rigidity by leaving the plate thickness of the pivotal support as it is, and without adding a separate reinforcing part. Occurrence prevention is achieved with a lightweight and simple configuration.

  The fuel injection device for a vehicle according to the present invention relates to a fuel injection device in which fuel is injected through a fuel injection port. Even if an external force is applied to the lid, the outer edge of the lid is pressed against the opening edge of the recess opening. In order to achieve the purpose of preventing the occurrence of scratches due to this pressure contact and preventing the occurrence of scratches with a light and simple configuration, The form for carrying out the present invention is as follows.

  That is, a fuel injection device in a vehicle is pivotally supported so as to be rotatable about a pivot shaft of a pivotal support member in a fuel injection port that opens from the inside of the vehicle body toward a recess formed in the outer surface of the vehicle body. A lid that can open and close the opening of the recess by its opening and closing rotation, and a part of the recess when the opening of the recess is fully opened by the opening and rotation of the lid. And a stopper for preventing further opening rotation of the lid. When the lid is fully open in the recess, when the stopper is displaced together with the lid in the axial direction of the pivot shaft, the support portion that abuts the stopper to restrict the displacement. Is formed in the recess.

  In order to explain the present invention in more detail, Example 1 will be described with reference to FIGS.

  1-4, the code | symbol 1 is a vehicle illustrated with the motor vehicle, and the arrow Fr has shown the front of the advancing direction of this vehicle 1. In FIG.

  The outer surface of the rear side portion of the vehicle body 2 of the vehicle 1 is formed by an outer plate 3 made of sheet metal. A door opening 4 for a rear side door is formed at the front portion of the outer plate 3, and a wheel house 5 for a rear wheel is formed at the rear lower edge portion of the outer plate 3. A fuel tank (not shown) is mounted inside the lower portion of the outer plate 3.

  A fuel injection device 9 that allows an operator to inject the fuel 8 is provided in the above-described on-vehicle fuel tank. Hereinafter, the fuel injection device 9 will be described.

  A recess 10 is formed in the lower outer surface of the outer plate 3 so as to open toward the outer side. An opening 11 for communicating the inside and outside of the vehicle body 2 is formed at the bottom of the recess 10. A fuel injection pipe 12 that extends upward and outward from the fuel tank is provided. The extending end of the fuel injection pipe 12 is a fuel injection port 13 that opens from the inside of the vehicle body 2 toward the inside of the recess 10 through the opening 11, so that the fuel injection port 13 can be opened and closed. A cap 14 is provided.

  A metal plate is pivotally supported on the inner surface of the recess 10, which is a part of the vehicle body 2, by a pivotal support 17, and the opening 18 of the recess 10 can be opened and closed by opening and closing rotations A and B. A lid 19 is provided.

  In the outer plate 3, a rectangular opening 22 is formed in a portion corresponding to the recess 10 in a side view of the vehicle body 2. Each part of the opening edge portion of the opening 22 is bent toward the inside of the vehicle body 2 to form an inward flange 23. Also, a pair of front and rear upper support pieces 24, 24 are integrally projected downward from the upper part of the inward flange 23, while a pair of front and rear lower supports are supported upward from the lower part of the inward flange 23. The pieces 25 and 25 are integrally projected.

  A sheet metal box 27 is provided from the inner side of the vehicle body 2 so as to be integrally fitted to the inward flange 23 and the upper and lower support pieces 24 and 25. An internal space 28 of the box 27 is opened to the outside of the vehicle body 2 through the opening 22. The box body 27 includes a bottom plate 29 that extends flatly in the front-rear and up-down directions, and a frame-shaped outer edge plate that integrally extends from each part of the outer edge portion of the bottom plate 29 toward the outer plate 3 in the width direction of the vehicle body 2. 30.

  The bottom plate 29 of the box 27 is fixed to the upper and lower support pieces 24 and 25 by the front and rear fixing means 32 and 33, whereby the box 27 is fixed to the outer plate 3. A sealing material 34 is interposed between the opening edge portion of the opening 22 of the outer plate 3 and the extended end edge portion of the outer edge plate 30 of the box 27 and is bonded to each other. The inner space 28 of the box 27 substantially forms the recess 10. The fixing means 32 and 33 are spot welded.

  The pivot support 17 is fixed to a front side of the lid 19 and a fixed side member 38 fixed to a front portion of the bottom plate 29 of the box 27 by a pair of upper and lower fixing means 37, 37 exemplified by rivets. , And a pivot side member 41 pivotally supported by the fixed side member 38 so that the shaft center 39 pivots around the longitudinal pivot shaft 40. By rotation of the rotation side member 41, the lid 19 together with the rotation side member 41 can be opened and closed and rotated A and B as described above.

  The lid 19 is inserted into the opening 18 when the lid 19 fully closes the opening 18 of the recess 10 (a dashed line in FIG. 1), and the outer surface thereof is flush with the outer surface of the outer plate 3. A lid main body 44, and a reinforcing plate 45 which is fixed to the inner surface of the outer edge of the lid main body 44 by spot welding and reinforces the lid main body 44. A rotating side member 41 of the pivot support 17 is integrally formed on the reinforcing plate 45.

  When the rear side of the lid 19 is opened and rotated A to the outside of the vehicle body 2 around the pivot shaft 40, the opening 18 of the recess 10 is opened. By doing B, the opening 18 of the recess 10 is closed. As described above, when the lid 19 rotates A and B, the longitudinal groove 48 that entirely accommodates the rotation trajectory of the front end portion of the lid 19 is formed on the inner surface of the front end portion of the box body 27. The vertical groove 48 improves the rigidity of the box body 27, that is, improves the rigidity of the recess 10.

  When the opening 18 of the recess 10 is fully opened by the opening rotation A of the lid 19 (solid line in FIGS. 1 and 2), the rear end surface 48a of the longitudinal groove 48 which is a part of the recess 10 is formed. A stopper 49 is provided in contact with the lid 19 to prevent further opening rotation A of the lid 19. The stopper 49 is formed integrally with the reinforcing plate 45 of the lid 19, and protrudes outward of the lid 19 in the surface direction of the lid 19. On the other hand, when the lid 19 is inserted into the opening 18 of the recess 10 by the closing rotation B of the lid 19 and the opening 18 is fully closed (a chain line in FIG. 1), the stopper 49 is The lid 19 is brought into contact with the front portion of the inward flange 23, which is the other portion of the recess 10, so that the lid 19 can be prevented from further closing rotation B.

  A trajectory accommodation groove 51 that extends in an arc shape around the axis 39 of the pivotal support 17 and that accommodates the entire rotation trajectory of the protruding end of the stopper 49 when the lid 19 is opened and closed. Is formed in the recess 10. The locus receiving groove 51 is formed so as to cross the longitudinal groove 48 in the recess 10. The protruding end portion of the stopper 49 has a semicircular shape, and the cross section of each portion of the trajectory receiving groove 51 in the longitudinal direction also has a semicircular shape. The inner surface of the locus receiving groove 51 is generally brought close to the turning locus of the stopper 49.

  A cap temporary placement portion 52 that is formed on the reinforcing plate 45 of the lid 19 and allows the cap 14 to be temporarily placed on the lid 19 is provided. Specifically, of the movement of the cap 14 in the axial direction C of the pivot shaft 40 from the upper side of the lid 19 toward the lid 19 side, the movement of the cap 14 downward causes the cap 14 to move toward the lid 19 side. Temporary placement is possible in the cap temporary placement portion 52.

  It is assumed that some external force (including component force) is applied to the lid 19 such as an external force applied to the cap temporary placement portion 52 of the lid 19 when the cap 14 is temporarily placed. The external support force causes the pivot support 17, the lid 19, and the box 27 to be elastically deformed, and the stopper 49 together with the lid 19 is at least in the axial direction of the pivot shaft 40 relative to the vehicle body 2. Suppose that it started to move toward C (dashed line in FIG. 4). At this time, regardless of the position of the rotation A or B of the lid 19, the stopper 49 which has started to be displaced as described above is brought into contact with the support to prevent the displacement of the lid 19 and the stopper 49. A portion 54 is formed in the recess 10. Specifically, the support portion 54 is formed by the inner surface of the locus accommodating groove 51.

  In addition, a lock piece 56 is integrally formed on the reinforcing plate 45 of the lid 19. The lock piece 56 is detachably locked to the vehicle body 2 side when the lid 19 fully closes the opening 18 of the recess 10. The lid 19 can be held in a fully closed position.

  When an operator injects fuel 8 into the vehicle fuel tank through the fuel injection port 13 using an injection gun or the like, first, the lid that closes the opening 18 of the recess 10 is used. 19 is opened and rotated A. When the opening 18 of the recess 10 is fully opened by the opening rotation A (solid line in FIGS. 1 and 2), the lid 49 is unnecessarily opened and rotated A. This is prevented by coming into contact with the rear end surface 48a of the longitudinal groove 48 which is a part of the recess 10.

  Next, the lid 19 includes a state in which the opening 18 of the recess 10 is fully opened. With the opening 18 open, the cap 14 that closes the fuel inlet 13 is gripped. 14 is removed from the fuel inlet 13 and the fuel inlet 13 is opened. At this time, the operator holding the cap 14 moves the cap 14 from above to the lower side, which is the axial direction C of the pivot shaft 40, so as to move toward the cap temporary placement portion 52 side. The cap 14 is placed on the cap temporary placement portion 52.

  This frees the operator from continuing to hold the cap 14. For this reason, thereafter, the operation of injecting the fuel 8 through the fuel injection port 13 using the injection gun or the like can be performed smoothly and easily for the operator.

  Then, after the desired fuel 8 is injected, the cap 14 is taken out from the cap temporary placement portion 52 by the procedure reverse to the above, and the fuel inlet 13 is closed by the cap 14. Next, the lid 19 is turned and closed B, and the opening 18 of the recess 10 is fully closed (a chain line in FIG. 1). Then, the injection operation is finished.

  Here, at the time of the above-described injection work, when the operator moves the cap 14 removed from the fuel injection port 13 to the lid 19 side and temporarily places it on the cap temporary placement portion 52, the cap is temporarily installed. It is assumed that an unnecessarily large external force is applied to the temporary placement portion 52 in the axial direction C of the pivot shaft 40. Then, the lid 19 tends to be elastically displaced relative to the vehicle body 2 toward the upper side or the lower side in the axial direction C of the pivot shaft 40 together with the stopper 49 due to the external force. However, in this case, the stopper 49 comes into contact with the upper surface or the lower surface of the support portion 54, and the displacement is restricted (a chain line in FIG. 4).

  Therefore, as described above, even if some external force is applied to the lid 19 through the cap temporary placement portion 52 during the injection operation, the outer edge portion of the lid 19 is the opening of the opening 18 of the recess 10. The press contact with the edge is prevented, and the occurrence of scratches due to the press contact is prevented.

  Moreover, the stopper 49 which prevents the further opening rotation A of the lid 19 when the opening 18 of the said recess 10 is fully opened is utilized for the generation | occurrence | production prevention of the said damage | wound. Therefore, the occurrence of the damage can be prevented without increasing the rigidity by leaving the plate thickness of the pivotal support 17 as it is and without adding a separate reinforcing part. Prevention of occurrence is achieved with a lightweight and simple configuration.

  Further, as described above, the support portion 54 accommodates the entire rotation locus of the stopper 49 around the pivot shaft 40 when the lid 19 is opened and closed and rotated A and B, and the rotation locus. It is formed by the inner surface of the locus accommodating groove 51 close to the surface.

  For this reason, regardless of the position of the rotation A or B of the lid 19, when the external force is applied to the lid 19, the stopper 49 is either one of the inner surfaces (in the longitudinal direction of the locus receiving groove 51 ( The lid 19 is prevented from being displaced by abutting against any part of the support portion 54. Therefore, the occurrence of scratches based on the external force is more reliably prevented.

  Although the above description is based on the illustrated example, the lid 19 may be pivoted up and down around the lateral pivot shaft 40 to open and close the opening 18 of the recess 10. The moving direction of the cap 14 for temporarily placing the cap 14 on the temporary placement portion 52 may be a horizontal direction toward the axial direction of the pivot shaft 40.

  The stopper 49 may be formed integrally with the lid main body 44 of the lid 19, and is provided separately from the reinforcing plate 45 of the lid 19, so that the lid main body 44 and the reinforcing plate 45 of the lid 19 are provided. It may be fixed by spot welding or a fastener. Further, when the lid 19 fully opens the opening 18 of the recess 10, in other words, the stopper 49 comes into contact with the rear end surface 48 a of the longitudinal groove 48. You may form so that only the rotation locus | trajectory of the said stopper 49 at the time of (including proximity | contact) may be accommodated.

  5 and 6 below show the second embodiment. The second embodiment is common in many respects to the configuration and operational effects of the first embodiment. Therefore, regarding these common items, common reference numerals are attached to the drawings, and redundant description thereof is omitted, and different points are mainly described. In addition, the configuration of each part in these embodiments may be variously combined in light of the object and operational effects of the present invention.

  In order to explain the present invention in more detail, the second embodiment will be described with reference to FIGS.

  The lid 19 opens and rotates A, and the stopper 49 comes into contact with the rear end surface 48a of the longitudinal groove 48 which is a part of the recess 10, and further opening rotation A of the lid 19 is prevented. Then, when the opening 18 of the recess 10 is fully opened, a fitting hole 59 for fitting a portion 49a which is a protruding end portion of the stopper 49 is formed in the rear end surface 48a of the vertical groove 48.

  And when the said stopper 49 is displaced toward the axial direction C of the said pivot shaft 40 based on the said external force with the said lid 19 which made the opening 18 of the said recess 10 fully open (a dashed-dotted line in FIG. 6), A support portion 54 that abuts a portion 49 a of the stopper 49 so as to restrict the displacement is formed at the hole edge portion of the fitting hole 59.
