Description

  The present invention relates to a fuel lock mechanism that can be locked so as not to open when a fuel lid of an automobile is closed and can be unlocked from a driver's seat. More specifically, the present invention relates to a fuel lock mechanism used together with an interlock mechanism that restricts the sliding door from being opened when the fuel lid is open.

  In a general fuel lid opener, a lever that is operated at a driver's seat and a rod that is locked so as not to open the fuel lid are connected by an inner cable. The rod is provided so as to be able to project and retract substantially parallel to the vehicle body (see Patent Document 1). On the other hand, in a car equipped with a sliding door, the movement of the door in the opening direction is restricted halfway when the sliding door is accidentally opened during refueling. There are those in which an interlock mechanism is interposed (see Patent Documents 2 and 3).

  For example, in Patent Document 2, when the fuel lid is opened and closed, it moves to the protruding position and the retracted position, and is locked to the retracted position by pressing, and further moves to the unlocking position when unlocked, and then moves to the protruding position after being unlocked. The intermediate stopper which is arranged so as to be freely retractable in the operating range of the sliding door is operated via an inner cable which is pushed and pulled by the movement of the plunger. Moreover, in patent document 3, the protrusion / retraction movement of the plunger is converted into the push / pull movement of the inner cable while changing the direction of the action by the link body provided to be rotatable with respect to the vehicle body. .

  Such a plunger push-in type fuel lid employs a fuel lock mechanism that operates in conjunction with opening and closing of the slide door. For example, when the fuel lid opening / closing control device of Patent Document 3 is provided with a fuel lock mechanism, an engagement hole is formed in the plunger or the link body, an engagement pin is provided so as to be engageable / detachable from the engagement hole, and the engagement It is conceivable that the pin is pulled or pushed / pulled by an operation lever or solenoid actuator via an inner cable.

  In the conventional fuel lock mechanism, play is provided between the plunger and the intermediate stopper so that the fuel lid can be opened and closed even when the intermediate stopper is frozen. However, if the door is locked after the fuel lid is opened, the door lock interlocking mechanism works and the fuel lid cannot be closed as it is. Therefore, it is necessary to close the fuel lid after releasing the door lock. However, it is not noticed and often takes time to close the fuel lid. An object of the present invention is to provide a fuel lock mechanism that can close the fuel lid even if the door is locked first.

  The fuel lock mechanism of the present invention is a fuel lock mechanism that operates in conjunction with the opening and closing of the slide door, and moves to the protruding position and the retracted position by opening and closing the fuel lid, locked to the retracted position by pushing, and further pushing The plunger that moves to the unlocking position and then moves to the projecting position after unlocking, the inner cable that is pushed and pulled by the movement of the plunger, and one end of the inner cable are connected, and the slide A stopper that can be freely moved in and out of the operating range of the door and the other end of the inner cable are connected, and a link that rotates and interlocks the protrusion / retraction movement of the plunger with the push / pull movement of the inner cable. Synchronized with the body and the sliding door lock / unlock An engaging pin that moves in a direction approaching the plunger, and the link body is provided with a lock lever having an engaged portion that can be engaged with the engaging pin, and the plunger is in the retracted position. When the engagement pin moves in the plunger direction due to the door lock, the engagement pin is engaged with the engaged portion of the lock lever so that the lock lever can rotate in a direction away from the engagement pin. It is connected to the link body, and the plunger is slidably connected to the link body.

  (1) In the fuel lock mechanism of the present invention, since the plunger is slidably connected to the link body, the plunger can be pushed in even when the engagement pin protrudes by the door lock in a state where the plunger protrudes, There is no need to unlock the door when locking the fuel lid. In addition, since the plunger is slidably connected to the link body and the link body rotates, the door lock switch can be changed from the indoor direction behind the fuel lid to the lateral direction. Therefore, the degree of freedom in layout can be ensured without sacrificing the indoor space.

  (2) In the fuel lock mechanism, the engaged portion has a hook-like shape having an opening in the base end direction of the lock lever, and is closer to the base end side from the opening toward the opening. When a protrusion is provided that prevents the engagement pin from being engaged with the engaged portion through the opening when the engagement pin moves while sliding with the lock lever. Even when the lock lever is moved by releasing the door lock, the lock lever is pressed in the direction perpendicular to the axis of the engagement pin while the engagement pin is engaged with the engaged portion. The lock lever rides on the engagement pin without giving a force. Therefore, even if the fuel lock and the door lock release occur at the same time, the door lock release operation does not stop halfway.

  (3) Further, in any of the fuel lock mechanisms, when a guide plate for guiding the tip of the engagement pin to the engaged portion is disposed in the vicinity of the lock lever, it is ensured by the presence of the guide plate. The engaging pin can be reliably guided to the engaged portion.

  (4) Further, in any of the fuel lock mechanisms, an engagement protrusion is provided on the plunger, and a guide means for restricting the movement of the engagement protrusion is provided in a housing portion that accommodates the plunger. A lock holding portion for holding the engaging protrusion at the locking position of the plunger, a protrusion holding portion for fixing the engaging protrusion at the protruding position of the plunger, and engaging the engaging protrusion when the plunger is retracted; A first inclined surface that is retracted while rotating the plunger from the protruding holding portion side position toward the lock holding portion side position, and while rotating the plunger from the lock holding portion side position toward the protruding holding portion side position. A second sloping surface to be retracted, and the plunger is a spherical protrusion for rotation that comes into contact with the plunger while rotating with a fuel lid at one end. The other end side is provided with a linear core part and a bottomed cylindrical body that is rotatably covered around the core part, and the bottom part of the cylindrical body can contact the link body. Yes, the plunger rotates by moving the spherical protrusion for rotation and moves from the projecting position to the lock holding position, and the plunger rotates by rotating the spherical protrusion for rotation and holds the lock. When moving from the position to the protruding position, even if the fuel lid comes into contact with the plunger, the plunger rotates smoothly, and the lock / unlock can be easily performed. Further, since the bottom of the bottomed cylindrical body comes into contact with the link body, the cylindrical body does not need to rotate, and the force is smoothly transmitted to the link body.

  A fuel lock mechanism 10 shown in FIG. 1 is supported in a substantially L-shaped case main body 11, a plunger 12 that can be moved in and out at one end of the case main body, and a support shaft 13 that is rotatable with respect to the case main body 11. In addition, a substantially triangular link body 14 that is rotated by the plunger 12 and an inner cable 15 connected to the link body are provided. In FIG. 1, the lid (reference numeral 11a in FIG. 8) is shown in a removed state. A hook-shaped lock lever 16 is swingably provided on the link body 14 by a support pin 17. Further, the case main body 11 is provided with an engagement pin 18 that engages with and disengages from the lock lever 16, and the engagement pin 18 is reciprocated by a solenoid actuator 19. Reference numeral 20 denotes a bracket for fixing the solenoid actuator 19 to the case body 11.

  The fuel lock mechanism 10 is used in an automobile equipped with an electric slide door, and the inner cable 15 is connected to the intermediate stopper 21 via a slide door stop switch SW. A push-pull cable is used from the fuel lock mechanism 10 to the slider in the slide door stop switch SW, and an inner cable 23 of a pull control cable is used from the slider to the operation member (cable end) 22 of the intermediate stopper 21. Both inner cables 15 and 23 are slidably guided along the curved path by outer casings (conduit) 24 and 25. The outer casings 24 and 25 are used for conventionally known control cables. Since the slide door stop switch SW and the intermediate stopper 21 are known, for example, from Patent Document 2, the detailed description is omitted.

  The case body 11 has a box shape, and a front end wall 26 is provided with a bottomed cylindrical storage portion 27. The front wall 26 is formed with a receiving portion 28 (see FIG. 8) protruding in the lateral direction. A cutout groove 30 for inserting the engagement pin 18 is formed in a lateral wall 29 continuous with the front wall 26. The lid 11a shown in FIG. 8 is provided with a projection that closes the opening of the notch groove 30, thereby restricting the swing of the engagement pin 18. A U-groove 33 that supports the casing cap 32 of the outer casing 24 is formed in the lower wall 31 of the case body 11. The opening of this U groove is also closed by a protrusion provided on the lid 11a.

  The case body 11 and the lid body 11a are made of synthetic resin, and the support shaft 13 that supports the link body 14 is formed integrally with the case body 11. A boss 14 a of a link body 14 is fitted to the support shaft 13, and a recoil spring (torsion coil spring) 34 that biases counterclockwise in FIG. 1 is mounted around the boss. Therefore, the plunger 12 is urged by the link body 14 in a direction in which it always protrudes. One end of the recoil spring 34 is locked to the case body 11, and the other end is locked to the link body 14.

  The link body 14 is a substantially triangular component and is rotatably supported by a support shaft 13 at a corner portion at a substantially right angle. The link body 14 can also be a synthetic resin molded product. The link body 14 acts as a bell crank that changes the operating direction of the plunger 12 and the operating direction of the inner cable 15 by approximately 90 degrees. Thereby, when attached to the vehicle body as shown in FIG. 8, the cable and the sliding door stop switch SW can be arranged along the side surface of the vehicle body. An arcuate contact portion 14b is formed at a portion corresponding to the proximal end of the plunger 12 of the link body 14, and the plunger 12 is urged by the link body 14 so that the plunger 12 is connected to the link body 14. It is slidably connected.

  The link body 14 is provided with a connection hole 14c with the inner cable 15. The connecting hole 14c is formed in a slightly long oval shape in the lateral direction in order to absorb the difference between the circular arc motion due to the rotation of the link body 14 and the linear reciprocating motion of the inner cable 15. A cable end 15 a made of a metal rod is fixed to the tip of the inner cable 15. The tip of the cable end 15a is bent at a substantially right angle and hooked into the connecting hole 14c. In this embodiment, the length from the rotation center to the portion that contacts the plunger is longer than the length from the rotation center to the locking portion of the inner cable. Therefore, the force received from the plunger 12 can be increased and transmitted to the inner cable.

  A lock holding member 35 shown in FIG. 2 is attached to the accommodating portion 27, and the plunger 12 is supported so as to be rotatable and axially movable. The lock holding member 35 includes a horizontally long protrusion that fits with the horizontally long receiving portion 28. The plunger 12 is a rod-shaped member, and is fixed at the tip so that the engagement piece 36 intersects the axis. A pair of engaging protrusions 37 are formed on the substantially central side surface in the longitudinal direction of the plunger 12. The engagement protrusion 37 is an elongated protrusion extending in the longitudinal direction of the plunger 12, and its lower end is an inclined surface. A deep cam groove 38 and a shallow cam groove 39 that cooperate with the engagement protrusion 37 of the plunger 12 are formed on the inner surface of the lock holding member 35. Further, a first inclined surface 41 and a second inclined surface 42 are formed on the inner surface of the accommodating portion 27 so as to cooperate with the inclined surface at the lower end of the engaging projection 37 of the plunger 12.

  These engaging projections 37, cam grooves 38 and 39, and inclined surfaces 41 and 42 are similar to the centering mechanism by the ballpoint pen knob. When the plunger 12 is pushed once, the plunger 12 is rotated by the first inclined surface 41. When the engagement protrusion 37 is fitted in the deep cam groove 38 and locked in the “retraction position (lock holding portion)”, the plunger 12 is pushed a little by the fuel lid 43, moved to the “lock release position”, and then released. The mechanism is rotated by the second inclined surface 42 and is fitted into the shallow cam groove 39 to be locked at the “projection position (projection holding portion)”. However, the rotation angle is 90 degrees. Thus, when the fuel lid 43 is pushed in and released a little, the plunger 12 pops out to the protruding position, pushes the fuel lid 43 open (see the lid open state S1 in FIG. 6), and is locked (locked and held) at that position. When the plunger 12 is pushed in again, the plunger 12 is locked (locked and held) in the retracted position (see the lid closed state S2 in FIG. 6).

  In this embodiment, the engagement piece 36 is vertically oriented (parallel to the case body 11) when the plunger 12 enters deeply, and the engagement piece 36 is laterally oriented when entering shallowly. As a result, the engagement piece 36 engages with the hook piece of the fuel lid 43 (see reference numeral 44 in FIG. 8). As a result, the fuel lid 43 cannot be pulled out from the outside. When the plunger 12 enters deeply and rotates the link body 14 in the clockwise direction, the inner cables 15 and 23 are pushed out or sent out, and the lever 21a of the intermediate stopper 21 in FIG. When the plunger 12 protrudes, the inner cables 15 and 23 are pulled, and the lever 21a of the intermediate stopper 21 is protruded.

  Since the plunger 12 rotates when moving in the protruding direction as described above, a spherical protrusion 12a for rotation protruding in a spherical shape is provided at the tip of the plunger 12 so that the plunger 12 can rotate smoothly while abutting the fuel lid. Yes. Furthermore, the rear end side of the plunger 12 employs a configuration in which a linear core portion 12b and a bottomed cylindrical body 12c that is rotatably covered around the core portion 12b are combined. Thereby, the contact with which the angle with the link body 14 changes becomes smooth. In addition, the code | symbol 45 of FIG. The sealing material 45 is formed from an elastic material such as rubber. The seal material 45 is provided with a barb 45a. Thereby, it is possible to prevent water droplets from being transmitted to the plunger 12.

  Next, the lock lever 16 and the engagement pin 18 attached to the link body 14 will be described with reference to FIGS. As shown in FIG. 5, a pair of left and right support pieces 46 are provided on the front wall 14 d of the link body 14 so as to support the lock lever 16 in a swingable manner. Further, below the front wall 14d, a bottom plate 47 that restricts the downward swinging end of the lock lever 16 is provided. The bottom plate 47 is formed with a groove 48 for holding the lock lever 16, and the front plate is formed with a guide plate 49 having an inclined surface for guiding the tip of the engagement pin 18 toward the engagement portion of the lock lever 16. It is said that. The tip of the engagement pin 18 is also tapered.

  A laterally elongated hole is formed at the tip of the telescopic rod (reference numeral 19a in FIG. 7a) of the solenoid actuator 19 that drives the engaging pin 18, and the base of the engaging pin 18 is bent at a substantially right angle. The portion is engaged with the elongated hole so as to be rotatable and movable in the longitudinal direction of the elongated hole. Although the solenoid actuator 19 can be operated from the driver's seat, it is normally interlocked with locking / unlocking of the door. When the door is locked, the engagement pin 18 protrudes, and when the lock is released, the engagement pin 18 retracts.

  As shown in FIG. 5, the lock lever 16 is formed by cutting a metal plate into a predetermined shape and bending it. The base 50 is bent into a U-shape that opens downward, and from one side of the base to the front. It consists of a hook-like engaged portion 51 that extends. As shown in FIGS. 3 and 4, the engaged portion 51 includes an intermediate portion 52 extending obliquely toward the vicinity of the center of the base, and continuously extending downward from the tip of the intermediate portion, and toward the rear at the lower end. And a free end 54 extending further rearward from the front end 53 and somewhat upward. That is, the engaged portion 51 has a substantially ring shape, and an opening portion (notch portion) 55 is formed between the free end 54 and the base portion 50. Since the opening 55 is provided, when the lock lever 16 is moved in the direction of the wall 26 when the fuel lid is opened, the fuel lock is activated to engage the engagement rod 18 and the engaged portion of the lock lever 16. Even when 51 is engaged, the engagement rod 18 is disengaged from the engaged portion 51 through the opening (notch portion) 55, so that the engaged portion 51 and the engagement rod 18 are engaged. Even if the solenoid actuator 19 is operated without causing the engagement rod 18 and the lock lever 16 to be caught by the engaged portion 51 pressing the engagement rod 18 toward the wall 26 in the combined state. The fuel lid can be opened. As shown in FIG. 3, the front end portion 53 is parallel to the base portion 50, and the free end 54 extends obliquely at the same angle as the intermediate portion 52.

  A hole 56 through which the support pin 17 is passed is formed in the base 50 (see FIG. 4). Further, a recoil spring 57 that constantly biases the lock lever 16 downward is mounted around the support pin 17 between the left and right plates of the base 50 (see FIG. 3). Further, a movement restricting portion 58 projects below the outer surface of the housing portion 27 of the case body 11. When the plunger 12 is pushed in the unlocked position direction with the engaging pin 18 moving in the direction of the plunger 12, the movement restricting portion 58 moves the engaging pin 18 from the locked position of the plunger 12 to the unlocked position. The movement of the distance up to the distance with the movement of the lock lever 16 is restricted.

  A smooth mountain-shaped protrusion 59 is formed on the lower side of the base portion of the engaged portion 51, that is, at the back of the opening 55 (see FIG. 4). Since the projection 59 has previously locked the door when the fuel lid is open, when the engaged portion 51 returns with the engaging pin 18 protruding, the engaging pin 18 is engaged with the engaged portion 51. It is for regulating not to enter.

  Next, the operation of the fuel lock mechanism 10 in the normal state will be described with reference to FIG. When the fuel lid 43 of FIG. 6 is open (lid open state S1), the plunger 12 protrudes and the link body 14 rotates counterclockwise. The engaging pin 18 is retracted in advance. In this state, the engagement protrusion of the plunger 12 is engaged with the shallow cam groove of the engagement member, and is in the protruding position (shallow engagement position). Further, since the inner cable 15 is pulled in the direction of the arrow P, the lever 21a of the intermediate stopper 21 in FIG. 1 is raised.

  From this state, the fuel lid 43 is closed while pushing the plunger 12 biased in the projecting direction by the link body 14, and when the plunger 12 is released when the plunger 12 exceeds the deep engagement position, the plunger 12 moves to the link body 14. Is pushed back a little and engaged at a deep position (retraction position). During this time, the plunger 12 is pushed back while rotating approximately 90 degrees. Further, the solenoid actuator 19 is operated (for example, ON operation), and the engagement rod 18 protrudes (protrusion position), and enters the engaged portion 51 of the lock lever 16 (see the lock state S3). In this state, since the engaging rod 18 is engaged with the engaged portion 51, the plunger 12 cannot be pushed in even if the fuel rod 43 is pushed from the outside. 3 also restricts the movement of the plunger 12 via the engagement rod 18.

  In the state in which the fuel lid 43 is closed (lid closed state S2), the inner cable 15 is not pulled in the direction of the arrow P, so the lever 21a of the intermediate stopper 21 in FIG. Therefore, the sliding door can be freely opened and closed.

  Next, in order to open the fuel lid 43, first, the solenoid actuator 19 is turned off by operating from the driver's seat, and the engagement pin 18 is retracted. As a result, the fuel lid 43 can be pushed in (lid closed state S2), and the driver or the refueling operator pushes the fuel lid 43 slightly to the unlocked position, and further releases his / her hand. As a result, the plunger 12 protrudes until it is locked at the protruding position (shallow locking position), and the fuel lid 43 is pushed open from the inside (see the open state S1). Further, the inner cable 15 is pulled out in the direction of the arrow P, the lever 21a of the intermediate stopper 21 is raised, and the operation in the opening direction of the sliding door is regulated from the middle to protect the fuel lid 43 and the fuel gun inserted into the fuel filler port. .

  Next, with reference to FIGS. 7a and 7b, the operation when the door lock is applied with the fuel lid opened will be described. In some cases, the fuel lid is unlocked at the gas station, and then the door is locked to prevent children from going out. In this case, when the door is locked, it tries to lock the fuel lid in conjunction therewith, and the solenoid actuator causes the engaging pin 18 to protrude (see FIG. 7a). In this state, since the lock lever 16 is moving forward, the engagement pin 18 does not enter the engaged portion 51 of the lock lever 16 and sinks to the lower side of the base portion 50 side than the angle-shaped protrusion 59 protruding downward. .

  When refueling is completed in this state and the fuel lid is closed, when the fuel lid is pushed in, the lock lever 16 swings upward and moves over the engagement pin 18 (FIG. 7b). Therefore, the fuel lid can be closed as it is without releasing the door lock. That is, in the prior art, it was necessary to once release the door lock, but in the fuel lock mechanism 10, it is not necessary to release the door lock. When the lock lever 16 is retracted, the engagement pin 18 does not enter the engaged portion 51 from the opening 55 of the lock lever 16 (see FIG. 7b). For this reason, there is no problem that a “slip” occurs between the arc-shaped locus of the lock lever 16 and the engagement pin 16 based on the rotation of the link body 14 and the next operation cannot be performed.

  Although the fuel lock mechanism used for the power slide door has been described in the above embodiment, it can also be used for a slide door that is manually opened and closed. Moreover, although the case where the engagement pin is operated by the solenoid actuator has been described in the above embodiment, it may be operated from the driver's seat via the control cable. Moreover, although the fuel lock mechanism interlock | cooperated with an intermediate | middle stopper was demonstrated, you may not interlock | cooperate with an intermediate | middle stopper. Moreover, although what has a hook-shaped engaged part was demonstrated as a lock lever, the lock lever provided with the ring-shaped engaged part without an opening part (code | symbol 55 of FIG. 4) is also employable. . In that case, the chevron protrusion (reference numeral 59 in FIG. 4) can be omitted.
