Description

  The present invention relates to a lid opening / closing device for a vehicle.

  Patent Document 1 discloses a conventional vehicle lid opening / closing device (hereinafter simply referred to as lid opening / closing device). This lid opening / closing device is provided between an opening provided in the vehicle body and a lid capable of opening and closing the opening. Specifically, a fuel supply port is disposed in the opening. The lid is a fuel lid that is opened and closed during fuel supply. The fuel lid is attached to the vehicle body so as to be displaceable between a closed position that closes the opening, an open position that opens the opening, and a pushing position that is pushed from the closed position to the opposite side of the open position.

  The lid opening / closing device includes a housing, and a push rod, an urging spring, a follower, and an electric actuator that are respectively accommodated in the housing. The push rod can project and be embedded in the housing. A lid locking portion that can be engaged with an opening formed in the fuel lid is formed at the tip of the push rod. The biasing spring biases the push rod to protrude from the housing. The follower is attached to the proximal end of the push rod. A plurality of sliders are formed on the outer peripheral surface of the follower. The electric actuator reciprocates the locking member by a motor and a worm gear.

  The housing is formed with a rod cam portion and a follower cam portion. The cam portion for the rod guides the push rod to rotate around the axis when the push rod protrudes and is buried in the housing. The follower cam portion can rotate the follower independently of the push rod, and can engage with the slider to lock the follower.

  In this lid opening / closing device, when the fuel supply operation is completed and the user or the like displaces the fuel lid from the open position to the closed position, the lid locking portion of the push rod protruding from the housing enters the opening of the fuel lid. At the same time, the push rod is pressed by the fuel lid and buried in the housing. At this time, the push rod is guided by the rod cam portion and rotates around the axis, whereby the lid locking portion also rotates and engages with the opening of the fuel lid. Further, the follower is rotated by the follower cam portion, and the slider is locked to the follower cam portion. Thus, the lid opening / closing device holds the fuel lid in the closed position.

  Further, in this lid opening / closing device, the push rod embedded in the housing is locked by the motor of the electric actuator, the worm gear, and the locking member, so that the push rod cannot be protruded from the housing. Become.

  On the other hand, when displacing the fuel lid to the open position, first, the locking member is separated from the push rod embedded in the housing by the electric actuator to release the locked state. In this state, the user or the like pushes the fuel lid in the closed position to displace it to the pushed position. As a result, the push rod is further buried in the housing, and the follower is guided by the follower cam portion and rotates. For this reason, the slider is not locked by the follower locking portion. As a result, the push rod is urged by the urging spring and protrudes from the housing. At this time, since the push rod is guided by the rod cam portion and rotates around the axis, the lid locking portion does not engage with the opening of the fuel lid. As a result, in the lid opening / closing device, the fuel lid can be displaced to the open position by the push rod biased by the biasing spring.

  Further, by assembling the back cover 13B to the housing body 13A, as shown in FIG. 5, the cylindrical portion 17D of the pole 17 enters the second through hole 130F of the back cover 13B. The release operation unit 29 is attached to the cylindrical portion 17D via the second X ring 37. At this time, the engagement operation 170 of the pole 17 engages with the release operation unit 29, whereby the release operation unit 29 is fixed to the pole 17. In this way, as shown in FIG. 4, the release operation part 29 can swing with the pole 17 while being located on the rear surface of the back cover 13B.

  The release operation unit 29 is connected to an opening lever provided in the passenger compartment of the electric vehicle 3 via a connecting rod. Thereby, it is possible to swing the release operation portion 29 and, consequently, the pole 17 through the release lever. The illustration of the connecting rod and the release lever is omitted. In addition, for example, by connecting a release cylinder 29 and a key cylinder that operates by locking and unlocking in addition to the release switch, the release operation unit 29 and the pole 17 can be configured to swing through them. Also good.

  The lid opening / closing device 1 operates as follows to hold the lid 7 in the closed state shown in FIG. 1 and change the lid 7 to the open state as shown in FIG. First, the case where the lid body 7 in the open state is held in the closed state will be specifically described.

  As shown in FIGS. 2 and 8, in the state where the lid body 7 is in the open position, the fork 15 swings to D1 indicated by the black solid line arrow in FIG. To change. At the unlatched position, the fork main body 15B swings so that the locking recess 151C faces the right side of the vehicle body 3A, that is, faces the lid 7, so that the striker 71 of the lid 7 is placed in the locking recess 151C. Make it possible to enter. Further, the latch portion 15C presses the protruding portion 17B of the pole 17 leftward through the pressing surface 152B. As a result, the pole 17 swings in the direction D4 indicated by the broken-line arrow in the figure against the urging force of the second torsion coil spring 24 and changes to the unblocked position.

  Then, as the lid 7 in the open position is displaced toward the closed position by the user or the like, as shown in FIG. 9, the striker 71 enters the locking recess 151C, and the second of the pole body 15B. The claw portion 151B is pressed in the left direction. As a result, the fork 15 swings in the direction D2 indicated by the black solid arrow in the figure while resisting the biasing force of the first torsion coil spring 23, and changes from the unlatched position to the latched position. Thereby, the fork main body 15 </ b> B and the striker 71 are engaged in the power supply port 5. At this time, the fork main body 15B swings so that the locking recess 151C faces downward, so that the striker 71 cannot escape from the locking recess 151C. Thus, the engagement between the fork main body 15B and the striker 71 cannot be released.

  Further, when the fork 15 is changed to the latch position, the pressing surface 152B does not press the protruding portion 17B in the latch portion 15C. For this reason, the pole 17 is swung in the direction D3 indicated by the broken line arrow in the figure by the urging force of the second torsion coil spring 24, and changes to the block position. As a result, the engagement surface 17A comes into contact with the latch surface 152A, and the pole 17 prohibits the fork 15 from swinging in the D1 direction by the biasing force of the first torsion coil spring 23. That is, the pole 17 prohibits the fork 15 from changing from the latched position to the unlatched position. Thus, the fork 15 in the latch position holds the striker 71 in the locking recess 151C, thereby holding the lid 7 in the closed position as shown by the solid line in FIG. For this reason, the power supply port 5 is kept closed by the lid body 7. Here, as shown in FIG. 9, when the fork 15 is in the latched position, the switching lever 19B of the switch 19 does not come into contact with either the first pressing protrusion 152C or the second pressing protrusion 152D. For this reason, the switch 19 maintains the OFF state.

  On the other hand, when the lid 7 in the closed state is displaced to the open state, first, as shown in FIG. 1, the user or the like presses the lid 7 in the closed state from the right side of the vehicle body. Thereby, as shown by the phantom line in the figure, the rear of the lid body 7 is pushed to the left side of the vehicle body 3A from the closed position, and the lid body 7 is displaced to the pushed position.

  When the lid body 7 is displaced to the pushing position, the lid body 7 further presses the second claw portion 151B in the left direction through the striker 71 as shown in FIG. For this reason, the fork 15 swings to the opposite side to the unlatched position, that is, swings further in the D2 direction than the latch position and changes to the detection position. Accordingly, the latch body 15C continues to contact the pole 17 through the pressing surface 152B, but the contact between the latch surface 152A and the engagement surface 17A is released. Further, by being in the detection position, the first pressing protrusion 152C is pressed while being in contact with the switching lever 19B, and the switching lever 19B is displaced to the right. As a result, the switch 19 is switched from the OFF state to the first connection state. Then, the control device supplies power to the electric motor 21A due to the switch 19 being in the first connection state.

  Specifically, the control device switches the electric switch 21 from the first connection state to the OFF state, that is, the state in which the rear side of the lid body 7 is pushed to the left side of the vehicle body 3A is eliminated, so that the electric motor 21A Supply power to By controlling the power supply to the electric motor 21A in this way, it is possible to prevent a situation in which power supply to the electric motor 21A is always performed while the lid body 7 is in the pushing position, and the operating load of the electric actuator 21 can be prevented. Can be reduced. For the control device, for example, a configuration in which power supply to the electric motor 21A is started immediately after the switch 19 enters the first connection state, or time measurement is started when the switch 19 enters the first connection state. After the elapse of time, it is possible to perform control according to the use situation, such as a configuration for supplying power to the electric motor 21A.

  By being fed by the control device, the electric motor 21A operates and rotationally drives the worm gear 21B. Therefore, as shown in FIG. 11, the worm wheel 21 </ b> C that meshes with the worm gear 21 </ b> B rotates in the direction D <b> 6 indicated by the white solid arrow while resisting the urging force of the third torsion coil spring 25. For this reason, the operated portion 17C of the pole 17 is pressed by the side wall of the guide groove 210 of the worm gear 21B, more specifically, the right side wall of the guide groove 210. Thus, the pole 17 swings in the direction D4 indicated by the broken-line arrow in the figure against the urging force of the second torsion coil spring 24 and changes to the unblocked position. As a result, the fork 15 is allowed to change from the latched position to the unlatched position. For this reason, as shown by the black solid line arrow in FIG. 8, the fork 15 changes to the D1 direction, that is, the unlatched position by the urging force of the first torsion coil spring 23. Thus, in the fork main body 15B, the locking recess 151C faces the lid body 7, and the striker 71 is in a state of being able to escape from the locking recess 151C. That is, the fork body 15B and the striker 71 are disengaged. Note that the worm wheel 21C rotated in the direction D6 contacts the stopper 29 shown in FIG. Thus, thereafter, the rotation of the worm wheel 21C in the direction D6 is restricted. Further, when the operation of the electric motor 21A is stopped, the worm wheel 21C is rotated in the direction D5 by the urging force of the third torsion coil spring 25, and returns to the state shown in FIGS.

  Here, in the lid opening / closing device 1, when the fork 15 changes to the unlatched position, the fork main body 15B swings while pressing the striker 71 to the right side of the vehicle body 3A by the first claw portion 151B. The recess 151 </ b> C faces the lid body 7. Thus, the lid opening / closing device 1 displaces the lid 7 held in the closed state to the open state.

  Then, as shown in FIG. 8, in the lid opening / closing device 1, when the fork 15 is in the unlatched position, the second pressing protrusion 152D is pressed against the switching lever 19B in the latch portion 15C, thereby pressing the switching lever 19B. Is moved to the left. Accordingly, the switch 19 is switched to the second connection state, and the control device supplies power to the illumination member 11 illustrated in FIG. 2 due to the switch 19 being in the second connection state. For this reason, while the lid body 7 is displaced to the open position, the inside of the power supply opening 5 is irradiated by the illumination member 11 (see FIG. 2). In addition, about a control apparatus, it is comprised so that the electric power supply to the illumination member 11 may be complete | finished, for example after the cover body 7 is displaced to an open position and the switch 19 switches to a 2nd connection state, and predetermined time passes. For example, it is possible to perform control according to the use situation.

  Further, in the lid opening / closing device 1, the user or the like swings the release operation portion 29 shown in FIG. 4 through the release lever, thereby changing the pole 17 from the block position shown in FIG. 9 to the unblock position shown in FIG. It is also possible. Thus, in the lid opening / closing device 1, when the user or the like operates the release lever, as described above, the fork 15 is changed to the unlatched position without opening the lid 7 without operating the electric actuator 21. It can also be displaced to a position.

  As described above, in the lid opening / closing device 1, the latch surface 152A of the latch body 15C and the engagement surface 17A of the pole 17 are brought into contact with each other, whereby the displacement of the fork 15 from the latched position to the unlatched position is caused by the pole 17. regulate. Thereby, the configuration of the lid opening / closing device 1 can be simplified, and a reliable operation can be performed even if the accuracy of parts such as the fork 15 and the pole 17 and the assembly accuracy are lowered.

  Further, in the lid opening / closing device 1, the fork 15 includes a shaft portion 15A, a fork main body 15B, and a latch body 15C. The fork main body 15B is located outside the protrusion 130 of the housing main body 13A, that is, the housing 131. For this reason, it is not necessary to form an entry portion or the like necessary for housing the striker 71 in the housing portion 131 with respect to the housing main body 13A. For this reason, in the lid opening / closing device 1, the configuration of the housing 13 can be simplified.

  Further, in the lid opening / closing device 1, since the electric actuator 21 includes the electric motor 21A, the worm gear 21B, and the worm wheel 21C, the configuration of the electric actuator 21 can be simplified.

  In the lid opening / closing device 1, the locking recess 151 </ b> C faces the lid 7 in the fork main body 15 </ b> B by changing to the latch position. In this state, the fork main body 15B is engaged with the striker 71 by causing the striker 71 to enter the locking recess 151C. For this reason, in this lid body opening / closing device 1, the relative positional relationship between the fork main body 15B and the striker 71 provided on the lid body 7 can be suitably engaged even if the assembly accuracy is reduced.

  Therefore, the lid opening / closing device of the present invention can realize a reduction in manufacturing cost.

  In particular, in the lid opening / closing device 1, since the latch body 15C also serves as a member for connecting / disconnecting the switch 19, the switch 19 is connected / disconnected, more specifically, the switch 19 is switched from the OFF state to the first connection state. Thus, a dedicated member for operating the electric actuator 21 or operating the illumination member 11 by switching the switch 19 from the OFF state to the second connection state is not necessary.

  Further, in the lid opening / closing device 1, the shaft portion 15A, the latch portion 15C, the pole 17, the switch 19, the electric actuator 21, the first to third torsion coil springs 23 to 25, the first to fifth electrodes 27A to 27E and the like are accommodated. It is accommodated in the part 131. And the accommodating part 131 is closed by the back cover 13B. For this reason, it is difficult for the switch 19, the electric actuator 21, and the like to be poorly energized due to dust adhesion or rainwater.

  Further, the pole 17 and the worm wheel 21C are coaxially supported by the housing body 13A by the swing pin 35. For this reason, it is possible to reduce the size of the housing 13 and thus the lid opening / closing device 1 as compared with the configuration in which the pole 17 and the worm wheel 21C are separately supported by the housing main body 13A.

  An illumination member 11 is provided in the power supply port 5. The illumination member 11 is supplied with power when the fork 15 swings to the unlatched position and the switch 19 is switched to the second connection state. Thereby, while the lid 7 is in the open state, the inside of the power supply port 5 is irradiated by the illumination member 11, so that the charging work is performed even when the electric vehicle 3 is charged at night or in the garage. Can be easily performed. Here, in the lid opening / closing device 1, the power supply to the electric actuator 21 and the power supply to the illumination member 11 can be switched by one switch 19. Thereby, compared with the case where a plurality of switches are provided, the lid opening / closing device 1 can be downsized. Further, in the lid opening / closing device 1, it is possible to reduce the number of parts and simplify the assembling work of the switch 19.

  While the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments and can be appropriately modified and applied without departing from the spirit thereof.

  For example, in the embodiment, the lid opening / closing device 1 holds the lid 7 of the power supply port 5 in the closed position or displaces it to the open position. A lid such as a mouth or a glove box may be held in a closed position or displaced to an open position.

  In the embodiment, power supply to the electric actuator 21 and power supply to the illumination member 11 are switched by one switch 19. However, the present invention is not limited to this. When the fork 15 swings to the detection position, the first connection state is established, and the switch for supplying power to the electric motor 21A of the electric actuator 21 and the fork 15 swings to the unlatched position. It is good also as a structure which provides in the 2nd connection state separately and the switch which supplies electric power to the illumination member 11.

  Further, the switch 19 may be disposed in the middle of the power supply circuit to the electric motor, and the electric motor 21 may be supplied with power through the switch 19 while the switch 19 is in the first connection state.

  The present invention is applicable to vehicles such as automobiles, buses, and industrial vehicles.
