Description

  The present invention relates to an energy supply port structure such as a fuel supply port and a charging port of a vehicle.

  In general, a fuel filler port of an automobile (vehicle) is provided in a fuel filler opening formed in a rear fender portion of a vehicle body. The refueling opening is opened and closed by a lid that opens and closes with one end edge as the center of rotation, the fuel refueling port faces the outside by opening the lid, and the fuel refueling port is shut off from the outside by closing the lid (For example, refer to Patent Document 1).

  In addition, an electric vehicle including a battery serving as a power source, such as an electric vehicle or a hybrid vehicle, includes a charging device for charging the battery. In the electric vehicle, the battery device is connected to the battery device from an external power source through a charging port. Charging is in progress. Similarly to the fuel filler port, the charging port is provided in an opening formed in the vehicle body (see, for example, Patent Document 2), and the charging port is opened and closed by opening and closing the lid.

  In order to easily open and close the lid, a structure is known in which a lid pushing device is provided on the vehicle body side of the opening to repeat generation of pushing biasing force and regulation of pushing biasing force by repeatedly pressing the lid. In this structure, the lid, which is urged to rotate toward the closing side, is pressed against the lid pushing device to generate the pushing urging force and maintain the lid on the open side to facilitate the opening, and the lid is pushed out into the closed state. By pressing against the device, the pushing biasing force is restricted and the closed state of the lid is maintained by the rotation biasing force.

  In addition, in order to easily open and close the lid, a convex portion for operation (insertion portion for inserting a hand) is provided at the end portion of the lid, and the lid that is pivotally biased to the closing side through the convex portion is opened. The structure is also known.

  In the energy supply port structure equipped with the lid extrusion device, a space for the lid extrusion device is required on the vehicle body side of the opening, the opening including the work space becomes large, and the enlargement of the lid is inevitable. . Further, in the structure in which the convex portion for operation is provided at the end portion of the lid, the continuity with the vehicle body is impaired when the lid is closed, and the appearance is inferior.

1 is an external view of a vehicle including an energy supply port structure as a reference example that is a premise of the present invention. It is a principal part external view in FIG. It is the III-III arrow directional view in FIG. It is an external view inside a lid. It is explanatory drawing at the time of opening of a lid. It is sectional drawing of the energy supply port structure which concerns on 1st Example of this invention. It is an external view inside a lid. It is an external view inside the lid of the energy supply port structure which concerns on 2nd Example of this invention.

  FIG. 1 shows an external appearance of an entire vehicle having an energy supply port structure as a reference example as a premise of the present invention, and FIG. 2 shows an external view of a lid.

  As the energy supply port, an oil supply port communicating with a tank of gasoline or alcohol fuel is described as an example. As the energy supply port, a charging port of an electric vehicle or a fuel (hydrogen fuel) supply port of a fuel cell vehicle can be applied.

  As shown in FIGS. 1 and 2, an opening 3 is formed in a rear side outer panel (outer panel) 2 of the vehicle 1, and a recess in which an oil supply port 6 of a fuel pipe 5 is attached to an inner panel 4 inside the opening 3. 7 is formed. A lid 8 is provided in the opening 3 of the outer panel 2 so as to be openable and closable. When the lid 8 is opened, the fuel filler opening 6 faces the outside. A stopper 9 is provided on the inner surface of the lid 8, and the stopper 9 abuts against the edge surface of the recess 7 when the lid 8 is closed, and the closed position is regulated.

  When the vehicle 1 is an electric vehicle, an insertion port for charging is attached to a portion of the fuel filler port 6 of the fuel pipe 5.

  Based on FIG. 3, FIG. 4, the support state of the lid 8 is demonstrated concretely.

  3 shows a cross-sectional state of the lid 8 as viewed in the direction of arrows III-III in FIG. 2, and FIG. 4 shows an external state of the lid 8 as viewed from the inside.

  As shown in the drawing, a bracket 11 is fixed to a side edge of the recess 7 of the inner panel 4, and a first rotation shaft 12 extending in the vertical direction is rotatably provided on the bracket 11. A tip edge portion of the hinge arm 14 of the hinge panel 13 is fixed to the first rotation shaft 12, and the hinge arm 14 (hinge panel 13) is supported so as to be rotatable about the first rotation shaft 12. The hinge panel 13 has an opening 15 at the center, and stoppers 9 are attached to the top and bottom of the tip.

  It is also possible to fix the first rotation shaft 12 to the bracket 11 and to rotatably support the tip edge portion of the hinge arm 14 on the first rotation shaft 12.

  That is, the distal end edge portion of the hinge arm 14 having a substantially U-shaped cross section is fixed to the first rotating shaft 12, and the hinge panel 13 is continuously formed at the proximal end portion of the hinge arm 14. 13 and the hinge arm 14 constitute a hinge. That is, the hinge is rotatably supported by the end portion (bracket 11) of the recess 7 around the first rotation shaft 12 via the bracket 11, and when the hinge 9 is rotated to the closing side, the stopper 9 is the edge of the recess 7. It abuts on the surface (the end on the side where the bracket 11 is not attached).

  An S-shaped spring 16 is attached across the bracket 11 and the hinge arm 14, and the hinge arm 14 (hinge panel 13) is biased to one side (the side on which the lid 8 is closed) by the spring 16, and is turned to the closing side. Is maintained. When the hinge arm 14 (hinge panel 13) is rotated beyond a predetermined angle, the spring 16 biases the hinge arm 14 (hinge panel 13) to the other side (the side on which the lid 8 opens), and rotates it to the opening side. Is maintained.

  The hinge panel 13 is provided with a second rotation shaft 17 extending in parallel along the first rotation shaft 12 so as to be rotatable. The second rotation shaft 17 has a second hinge plate 21 as a second hinge. It is attached. That is, the second hinge plate 21 is supported so as to be tiltable about the second rotation shaft 17 with respect to the hinge panel 13.

  It is also possible to fix the second rotation shaft 17 to the hinge panel 13 and to support the second hinge plate 21 so as to be rotatable with respect to the second rotation shaft 17.

  The lid 8 is fixed to the second hinge plate 21, and the lid 8 is tiltable with respect to the hinge panel 13. That is, the lid 8 can be tilted at a predetermined angle with the second hinge plate 21 with respect to the hinge panel 13 in a state where the hinge panel 13 does not rotate around the first rotation shaft 12. An edge frame 25 is formed on the periphery of the lid 8. Further, a locking projection 18 is formed on the outer side of the hinge arm 14 (on the lid 8 side). When the lid 8 is tilted, the back surface of the lid 8 abuts on the locking projection 18 and the tilt angle of the lid 8 is restricted. Is done.

  A convex hook 22 is formed inside the second hinge plate 21, and the convex hook 22 extends from the opening 15 to the inside of the hinge panel 13. An inclined hook 23 is provided in the opening 15 of the hinge panel 13 corresponding to the convex hook 22, the second hinge plate 21 is tilted to the closed side, and when the convex hook 22 gets over the inclined hook 23 due to elastic deformation, Tilt of the second hinge plate 21 toward the closing side is maintained, and tilting in the opening direction is restricted. On the other hand, when the second hinge plate 21 is tilted to the open side while the second hinge plate 21 is regulated to the closed side, the convex hook 22 gets over the inclined hook 23 along with the elastic deformation and the regulation is released. .

  Instead of providing the convex hook 22 and the inclined hook 23, a compression spring is provided over the hinge arm 14 and the lid 8, and the tilting of the lid 8 in the opening direction with respect to the hinge panel 13 is restricted by the urging force of the compression spring. Is also possible. In this case, the lid 8 can be tilted to the open side by pushing the lid 8 in the direction in which the compression spring is contracted.

  The lid 8, the hinge panel 13, the hinge arm 14, and the second hinge plate 21 are made of sheet metal and have a desired shape by easy processing. Further, the size of the recess 7 of the inner panel 4 is set to a minimum gap shape in which a work space for the fuel filler 6 is secured. For this reason, the area of the opening 3 can be minimized, and the lid 8 can be downsized. Moreover, in the state in which the lid 8 is closed, the outer panel 2 and the lid 8 are substantially flush with each other, and it is possible to suppress a decrease in appearance.

  The state of the opening / closing operation of the lid 8 configured as described above will be described with reference to FIG.

  5A shows a state in which the lid 8 is tilted, FIG. 5B shows a state in which the lid 8 has begun to open, and FIG. 5C shows a state in which the lid 8 has been opened.

  Normally, the hinge (hinge panel 13 and hinge arm 14) is urged in the closing direction by the urging force of the spring 16, and the convex hook 22 is fitted to the inclined hook 23 so that the lid 8 is closed on the hinge panel 13. It is in a regulated state. That is, the state in which the lid 8 is closed is maintained by the biasing force of the spring 16 and the restriction of the restriction member (see FIG. 2).

  When the lid 8 is opened, as shown in FIG. 5A, the convex hook 22 is fitted to the inclined hook 23 by pushing the lid 8 between the first rotating shaft 12 and the second rotating shaft 17 inward. The lid 8 tilts around the second rotation axis together with the second hinge plate 21 until the joint is released and the back surface of the lid 8 abuts against the locking projection 18. In this state, a space for operation is generated between the end portion of the lid 8 and the outer panel 2, and the lid 8 can be operated in the opening direction.

  As shown in FIG. 5B, the hinge arm 14 and the hinge panel 13 rotate around the first rotation shaft 12 against the urging force of the spring 16 by opening the end of the lid 8 forward. The lid 8 rotates to the opening side together with the hinges (hinge panel 13 and hinge arm 14). Up to a predetermined angle, the spring 16 contracts, and the urging force on the extension side of the spring 16 generates a turning force on the lid 8 (hinge) toward the closing side.

  Further, when the lid 8 is rotated to the open side to reach a certain angle, the spring 16 becomes neutral, and when the lid 8 is further rotated to reach a certain angle or more, the spring 16 is contracted again to the extended side. A biasing force is generated. As a result, an opening-side turning force is generated in the lid 8, and as shown in FIG. 5C, turning force is generated in the opening 8 on the opening side, and the fully-open state of the lid 8 is maintained.

  The energy supply port structure described above releases the fitting of the convex hook 22 to the inclined hook 23 and tilts the lid 8 around the second rotating shaft 17 with respect to the hinge (hinge panel 13 and hinge arm 14). The lid 8 can be opened and closed (a gap with the outer panel 2), and the lid 8 is opened using the gap to rotate the lid 8 around the first rotation shaft 12 together with the hinge. The lid 8 can be opened.

  For this reason, there is no part which protrudes outside when the lid 8 is closed, the continuity with the outer panel 2 is not impaired, and there is no possibility that the appearance is lowered. Further, since there is no member for pushing out the lid 8 on the concave portion 7 side, the opening 3 of the outer panel 2 can be made to have a minimum area enough to secure a work space.

  Accordingly, it is possible to maintain the operability satisfactorily without deteriorating the appearance, and to reduce the size of the lid 8 by making the opening 3 of the outer panel 2 the minimum size. By reducing the size of the lid 8, when the lid 8 is opened at the time of refueling (during refueling), the concave portion 7 exposed to the outside can be suppressed to the minimum. The impact can be minimized.

  In the above-described reference example, the fuel filler port has been described as an example. However, when the present invention is applied to the charging port, for example, charging may be performed outside at night to keep the lid 8 open. However, since the intrusion of foreign matter from the outside and the influence of the external environment can be suppressed to the minimum, it is extremely effective to make the lid 8 small.

  The energy supply port structure according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 6 shows a cross-sectional state of the energy supply opening according to the first embodiment of the present invention, and FIG. 7 shows an external appearance of the lid as viewed from the inside. FIGS. 6 and 7 correspond to FIGS. 3 and 4 of the reference example as a premise of the present invention, and the same members and the same functional members as those of the preferential reference example are denoted by the same reference numerals and detailed description will be given. Is omitted.

  The first embodiment shown in FIGS. 6 and 7 has a configuration in which a lock means is provided in place of the convex hook 22 and the inclined hook 23 of the reference example as a premise.

  As shown in the figure, the inner panel 4 is provided with a lock cylinder 31, and the lock cylinder 31 is provided with a lock pin 32 that can be moved in and out. On the other hand, a hook 33 is integrally provided inside the second hinge plate 21, and the lock pin 32 of the lock cylinder 31 protrudes with the lid 8 closed, so that the lock pin 32 is engaged with the hook 33. Thus, the opening side of the lid 8 is prevented from being turned (locked).

  In addition, a tension spring 34 is attached across the lid 8 and the hinge arm 14, and the spring force of the tension spring 34 constantly biases the lid 8 around the second rotation shaft 17 to the opening side with respect to the hinge panel 13. Has been. When the lid 8 is closed against the spring force of the tension spring 34 and the lock pin 32 is engaged with the hook 33, the lid 8 is maintained in the closed state while being urged to the open side. In this state, when the lock pin 32 is released from the hook 33 (when the lock is released), the lid 8 tilts around the second rotation shaft 17 with respect to the hinge panel 13 by the spring force of the tension spring 34, and the end of the lid 8 is moved. An operation space is generated between the outer panel 2 and the outer panel 2.

  When an operation signal is input to the ECU 40 by operating the operation switch 35 operated from the cab, a lock pin operation signal is given to the lock cylinder 31, and the lock pin 32 is moved in and out by the lock cylinder 31. When the lock cylinder 31 is manually operated, a rope body that operates the lock cylinder 31 in conjunction with the operation of the operation switch 35 is provided.

  By operating the operation switch 35 in a state in which the lid 8 is closed, the lock pin 32 is moved down and removed from the hook 33, and the lid 8 is moved against the hinge panel 13 by the spring force of the tension spring 34. Tilt around the axis 17. The lid 8 can be fully opened using the space for operation generated between the end portion of the lid 8 and the outer panel 2.

  Note that when the lid 8 is closed, the lock pin 32 is pushed by the hook 33 and is partially retracted, and the lock pin 32 protrudes at the fully closed position so that the fully closed state of the lid 8 is locked. .

  Therefore, the operability of the opening operation of the lid 8 can be maintained extremely well without deteriorating the appearance, and the size of the opening 8 of the outer panel 2 can be minimized to reduce the size of the lid 8.

  An energy supply port structure according to a second embodiment of the present invention will be described based on FIG.

  FIG. 8 shows the external appearance of the inside of the lid of the energy supply port structure according to the second embodiment of the present invention. FIG. 8 shows a state corresponding to FIG. 3 of the reference example and FIG. 7 of the first example, and the same members and the same function members as those of the reference example and the first example are denoted by the same reference numerals and redundant description is omitted. It is.

  In the second embodiment shown in FIG. 8, the lid 41 is made of resin, and the hook 42 is formed integrally with the lid 41 in place of the hook 33 of the first embodiment. Further, the second hinge plate 21 is not provided.

  As shown in the figure, a hook 42 is integrally formed on the back surface of the resin lid 41. In addition, tilt support members 43 are integrally formed at portions corresponding to the top and bottom of the second rotation shaft 17 on the back surface of the lid 41. An upper portion and a lower portion of a second rotation shaft 17 that is rotatably provided on the hinge panel 13 are fixed to the tilt support member 43, and the lid 41 is tiltable about the second rotation shaft 17 with respect to the hinge panel 13. It is supported by.

  The second pivot shaft 17 may be fixed to the hinge panel 13 and the tilt support member 43 may be pivotably supported with respect to the second pivot shaft 17.

  As in the first embodiment, a tension spring 34 is attached across the lid 41 and the hinge arm 14, and the lid 41 is opened to the hinge panel 13 around the second rotation shaft 17 by the spring force of the tension spring 34. Is always urged to rotate.

  When the operation switch 35 (see FIG. 6) is operated in a state where the lid 41 is closed, the lock pin 32 is moved down and removed from the hook 42, and the lid is pressed against the hinge panel 13 by the spring force of the tension spring 34. 41 tilts around the second rotation shaft 17. The lid 41 can be fully opened by using an operation space generated between the end portion of the lid 41 and the outer panel 2.

  Therefore, it is possible to maintain the operability of the opening operation of the lid 41 very satisfactorily without reducing the appearance, and to reduce the size of the lid 41 by minimizing the opening 3 of the outer panel 2. In addition, since the hook 42 and the tilting support member 43 are formed integrally with the lid 41, the degree of freedom of the shape of the lid 41 can be improved.

  The operation of the lock cylinder 31 is not limited to that performed by the operation switch 35 in the driver's seat, and can be operated in conjunction with a door lock by a center door locking function such as a keyless entry.
