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, a support shaft, a push rod, and a follower. The support shaft is formed integrally with the housing and extends so as to pass through the opening in the axial direction.

  The push rod has a cylindrical shape extending around the axis, and a coil spring is provided inside. Moreover, the lid latching | locking part which can be engaged with the opening formed in the fuel lid is formed in the front-end | tip of a push rod. The push rod is inserted through the support shaft. Thus, the push rod is supported by the support shaft, and in the axial direction, between the first position corresponding to the open position, the second position corresponding to the closed position, and the third position corresponding to the push-in position. It can be reciprocated. At this time, the push rod is urged toward the first position by the coil spring. Further, the push rod is supported by the support shaft and can be rotated around the axis, and can be displaced between the latch position and the unlatch position. 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 housing is formed with a rod cam portion and a follower cam portion. When the push rod reciprocates in the first direction, the rod cam portion guides the push rod to rotate around the axis as described above. 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 enters the opening of the fuel lid in the push rod at the first position. . Then, the push rod is pressed by the fuel lid and displaced to the second position. At this time, the push rod is guided by the rod cam portion and rotates around the axis. As a result, the push rod is displaced to the latch position, and the lid locking portion locks the fuel lid. Further, the follower is rotated by the follower cam portion, and the slider is locked to the follower cam portion. For this reason, the push rod is restricted from being displaced from the second position to the first position. Thus, the lid opening / closing device holds the fuel lid in the closed position.

  On the other hand, when the fuel lid is displaced to the open position, the user or the like pushes the fuel lid in the closed position and displaces it to the pushed position. Accordingly, the push rod is displaced from the second position to the third position, 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 displaced from the third position to the first position by the urging force of the coil spring. At this time, the push rod is guided by the rod cam portion, rotates around the axis, and is displaced to the unlatched position. For this reason, the lid locking portion does not lock the fuel lid. Thus, in this lid opening / closing device, the fuel lid can be displaced to the open position by the push rod displaced to the first position.

  However, in the conventional lid opening / closing device, when the lid is held in the closed position and the lid is displaced to the open position, each component operates in a complicated manner. For this reason, in this lid body opening / closing apparatus, high accuracy is required for each component. In addition, since each component needs to be assembled in a complicated manner, high assembly accuracy is also required. For this reason, in this lid opening / closing device, strict quality control is required at the time of manufacture of each component and assembly of each component, and it is difficult to reduce the manufacturing cost. Further, in this lid opening / closing device, since the components easily slide or collide with each other, repeated opening / closing of the lid may cause wear or chipping in each component, and durability. It is also difficult to improve.

  The present invention has been made in view of the above-described conventional circumstances, and it is an object to be solved to provide a vehicle lid opening / closing device capable of realizing a reduction in manufacturing cost and an improvement in durability. .

A vehicle lid opening / closing device of the present invention is a vehicle lid opening / closing device provided between an opening provided in a vehicle body and a lid capable of opening and closing the opening.
The lid body is displaceable to a closed position that closes the opening, an open position that opens the opening, and a push position that is pushed from the closed position to the opposite side of the open position,
The lid opening / closing device includes a housing provided on the vehicle body,
A first position corresponding to the open position and a second position corresponding to the closed position extend in a first axis parallel to a first direction extending so as to pass through the opening. And a third position corresponding to the push-in position, and is supported by the housing so as not to rotate around the first axis and is biased toward the first position. A linear shaft,
The linear shaft extends around the first axis, is reciprocally movable in the first direction, and is supported by the linear shaft so as to be rotatable about the first axis, and the linear shaft is in the second position or A rotating shaft that displaces to a latch position that locks the lid if in the third position, and that displaces to an unlatched position that does not lock the lid if the linear motion shaft is in the first position;
A cam member provided in the housing and formed with an opening and closing profile;
A guided portion provided on the linear motion shaft and guided by the opening and closing profile;
The open / close profile circulates the guided portion that reciprocates with the linear motion shaft by the swing of the cam member or the swing of the guided portion, and the linear motion shaft is moved from the first position to the second position. If the linear movement shaft is displaced from the second position to the third position, the linear movement shaft is restricted from returning from the second position to the first position. The shaft is configured to allow the shaft to pass through the second position and return to the first position.

  In the lid opening / closing device of the present invention, the guided portion is provided on the linear motion shaft. Here, since the linear motion shaft is supported so as not to rotate around the first axis with respect to the housing, the guided portion also cannot rotate around the first axis. Then, the opening / closing profile formed on the cam member circulates the guided portion by the swing of the cam member or the swing of the guided portion.

  Thus, in this lid opening / closing device, when the lid is displaced from the open position to the closed position, the linear movement shaft is displaced from the first position to the second position. Further, the rotation shaft is also supported by the linear movement shaft, rotates around the first axis, and is displaced to the latch position to lock the lid. At this time, since the opening / closing profile restricts the linear movement shaft from returning from the second position to the first position, the rotating shaft maintains the latch position and holds the lid in the closed position.

  On the other hand, if the lid body is displaced from the closed position to the pushed-in position, the linear movement shaft is displaced from the second position to the third position. As a result, the open / close profile allows the linear motion shaft to return from the second position to the first position, so that the linear motion shaft is displaced from the third position to the first position through the second position. Further, when the linear movement shaft is displaced to the first position, the rotation shaft is displaced from the latch position to the unlatching position. For these reasons, in this lid opening / closing device, the lid can be displaced to the open position.

  Thus, the structure of the lid opening / closing device is simplified compared to the conventional lid opening / closing device. For this reason, in this lid body opening and closing device, it is possible to hold the lid body in the closed position and displace the lid body to the open position even if the accuracy of each component and assembly is not so high. . For this reason, in this lid opening / closing device, strict quality control is not necessarily required when manufacturing each part and when assembling each part. Also, in this lid opening / closing device, compared to the above conventional lid opening / closing device, it is difficult for the components to slide or collide with each other. Wear or chipping is difficult to occur.

  Therefore, in the lid opening / closing device of the present invention, the manufacturing cost can be reduced and the durability can be improved.

  The cam member is provided in the housing so as to be swingable around a second axis parallel to the second direction orthogonal to the first direction, and directed toward one side of the first direction and the third direction orthogonal to the second direction. Preferably it is energized. The guided portion is preferably formed so as to protrude in the second direction from the linear motion shaft. The opening / closing profile further includes a first profile extending away from the second axis, and a second profile positioned on the other side in the third direction with respect to the first profile and extending away from the second axis; A first connection for connecting the first profile and the second profile on the opening side in the first direction, and a second connection for connecting the first profile and the second profile on the opposite side of the opening in the first direction Part. When the linear motion shaft is displaced from the first position to the second position, the open / close profile guides the guided portion from the first connection portion to the second connection portion via the first profile. If the second position is displaced to the third position, the guided part is preferably guided from the second connection part to the first connection part via the second profile.

  In this case, the opening and closing profile circulates through the guided portion as the cam member swings around the second axis. As a result, the open / close profile restricts the linear motion shaft from returning from the second position to the first position by guiding the guided part from the first connection part to the second connection part via the first profile. To do. The open / close profile allows the linear motion shaft to return to the first position by guiding the guided portion from the second connection portion to the first connection portion via the second profile.

  It is preferable that the cam member has a circulation restricting portion that restricts the guided portion from circulating in the reverse direction along the opening / closing profile. In this case, since the guided portion is restricted from circulating in the reverse direction in the opening / closing profile as the linear motion shaft reciprocates in the first direction, the lid body is locked and released by the rotating shaft. Can be reliably performed.

  The circulation restricting portion is swingably supported by the cam member, is disposed between the second profile and the first connection portion, and abuts on a guided portion that is directed from the second profile toward the first connection portion. While swinging, it is preferable that it is configured not to swing if it comes into contact with a guided portion that is going from the first connecting portion toward the second profile. In this case, it is possible to reliably regulate the reverse circulation of the guided portion while simplifying the circulation regulating portion.

  The lid opening / closing device of the present invention is supported by the housing so as to be displaceable, and a lock position for restricting the cam member from swinging to one side in the third direction, and the cam member swinging to one side in the third direction. It is preferable to further include a lock member that can be displaced between the unlock position and the unlock position.

  In this case, if the lock member is in the lock position, the cam member is restricted from swinging to one side in the third direction. As a result, the guided portion is changed from the second connection portion to the second profile. It becomes impossible to move towards. For this reason, it is restricted that the linear motion shaft in the second position returns to the first position. On the other hand, if the lock member is in the unlocked position, the guided portion can move from the second connecting portion toward the second profile, so that the linear motion shaft is allowed to return to the first position.

  The lock member may include an electric motor that rotationally drives the worm gear, and a worm wheel that is swingably supported by the housing, meshes with the worm gear, and is displaceable between a lock position and an unlock position. preferable. The worm wheel is preferably provided with an action portion that abuts the cam member at the locked position and is separated from the cam member at the unlocked position.

  In this case, when the worm wheel is in the locked position, the action portion comes into contact with the cam member, so that the cam member is restricted from swinging to one side in the third direction. On the other hand, when the worm wheel is in the unlocked position, the action portion is remote from the cam member, so that the cam member is allowed to swing to one side in the third direction.

  It is preferable that the worm wheel is provided with a release operation unit that can be operated from within the vehicle body. And it is preferable that a worm wheel is displaced to an unlock position by the displacement of a cancellation | release operation part. In this case, the worm wheel can be displaced to the unlock position even when the electric motor does not operate due to, for example, insufficient storage amount of the battery provided in the vehicle body, and the cam member can be swung. It becomes possible to release the regulation.

  The housing is provided with a switch that is in the first state when the linear shaft is in the second position, and is in the second state when the linear shaft is in the first position or the third position. It is preferable.

  In this case, whether or not the lid is in the open position can be detected depending on whether the switch is in the first state or the second state. Further, by providing the switch in the housing and unitizing it, it is possible to suppress the complexity and increase in size of the lid opening / closing device.

  The vehicle body is preferably provided with a slide member that is slidably supported along the vehicle body and is displaceable to a cover position that covers the opening. The lid opening / closing device is supported by the base member so as to be displaceable by the base member, and is displaced to the non-detection position if the linear motion shaft is in the first position, while the linear motion shaft is the second one. A detection unit that is displaced to the detection position if it is in the position or the third position and a detection unit that is provided in the vicinity of the slide member and that restricts the slide member from being displaced to the cover position if the detection unit is in the non-detection position. It is preferable to further include a restricting portion that allows the slide member to be displaced to the cover position if the portion is at the detection position.

  In this case, it is possible to restrict the slide member from being displaced to the cover position while the lid is in the open position. As a result, it is possible to prevent interference between the slide member and the lid in the open position. For this reason, it becomes possible to increase the kind of vehicle which employ | adopts the cover body opening / closing apparatus of this invention.

The first torsion coil spring 25 is attached in the accommodating portion 11 </ b> C by inserting the first coil portion 25 </ b> A through the shaft portion 116. The first arm portion 25B extends upward from the first coil portion 23A and is locked to the housing body 11B. On the other hand, the second arm portion 25 </ b> C extends from the first coil portion 25 </ b> A toward the right side and is locked to the through lever 39. As a result, the first torsion coil spring 25 urges the through lever 39 in the direction D3. Further, the first torsion coil spring 25 urges the heart cam 17 toward the D1 direction via the through lever 39.

  As shown in FIG. 7, the lock member 19 includes an electric motor 19A, a worm gear 19B, and a worm wheel 19C. Public goods are adopted for the electric motor 19A. As shown in FIG. 7, each end of the first and second electrodes 23A and 23B is connected to the electric motor 19A.

  The worm gear 19B is connected to the electric motor 19A and is rotationally driven by the electric motor 19A. The worm wheel 19C is formed with an action portion 190 and a connecting shaft 191. The action part 190 has a substantially rectangular plate shape, and extends upward of the worm wheel 19C. The connecting shaft 191 extends toward the front of the worm wheel 19C. That is, the connecting shaft 191 extends in the same direction as the shaft portions 115 to 117.

  The switch 21 includes a switch body 21A and a contact portion 21B. One end of each of the third and fourth electrodes 23C and 23D is connected to the switch body 21A. The contact portion 21B is provided on the switch body 21 so as to be swingable. The switch 21 is turned off when the contact portion 21B is not pushed into the switch body 21, and is turned on when the contact portion 21B is pushed into the switch body 21. This OFF state corresponds to the first state in the present invention, and the ON state corresponds to the second state in the present invention.

  As shown in FIG. 12, the linear motion shaft 13, the rotation shaft 15, the lock member 19, the switch 21, and the like are also attached to the housing body 11B. Here, the linear motion shaft 13 and the rotation shaft 15 are attached to the housing main body 11B after the heart cam 17, the through lever 39, and the first torsion coil spring 25 are attached to the housing main body 11B as described above. For ease of explanation, in FIG. 12A, a detection lever 53 described later is indicated by a virtual line, and the shape of the coil spring 27 is simplified. In FIG. 12B, the linear shaft 13 and the rotating shaft 15 are indicated by phantom lines, and the coil spring 27 and the detection lever 53 are not shown. The same applies to FIGS. 13 and 14.

  As shown in FIG. 12A, the linear motion shaft 13 is disposed in the accommodating portion 11C with the sliding portion 132 of the base portion 13B facing the slide base 118. At this time, the guided portion 37 is arranged in the opening / closing profile 17C of the heart cam 17 as shown in FIG. Further, the shaft portion 13A of the linear motion shaft 13 passes through the shaft hole 114 and the shaft cover 35 shown in FIG. 7 and protrudes to the left side of the housing main body 11B.

  On the other hand, the rotation shaft 15 passes the main body portion 15A through the shaft hole 114 and the shaft cover 35 from the left side of the housing main body 11B. At this time, as shown in FIG. 9, the guide protrusion 115 </ b> A of the shaft portion 115 is disposed in the guide recess 151. Thus, by inserting the main body portion 15A into the shaft hole 114 and the shaft cover 35, the shaft portion 13A of the linear motion shaft 13 is inserted into the shaft hole 150 of the rotating shaft 15 as shown in FIG. Then, the cap 41 is fixed to the fixing portion 13D of the linear motion shaft 13. As a result, the rotation shaft 15 is supported by the linear motion shaft 13 and the both cannot be separated.

  In this way, as shown in FIG. 12, the linear movement shaft 13 and the rotation shaft 15 are attached to the housing body 11B. More specifically, the linear motion shaft 13 and the rotation shaft 15 are disposed in front of the heart cam 17, the through lever 39, and the first torsion coil spring 25 in the housing portion 11 </ b> C. Then, when the sliding portion 132 slides on the slide base 118 in the first axis X1 direction, that is, in the left-right direction in the accommodating portion 11C, the linear motion shaft 13 and the rotary shaft 15 reciprocate in the left-right direction. It is possible to do. Here, when the sliding portion 132 slides in the left-right direction on the slide base 118, the linear motion shaft 13 reciprocates only in the left-right direction. On the other hand, when the revolving shaft 15 reciprocates in the left-right direction, the guide protrusion 115A moves in the guide recess 151 as shown in FIG. For this reason, the rotation shaft 15 moves in the left-right direction together with the linear movement shaft 13 and rotates independently of the linear movement shaft 13 around the first axis X1 as indicated by a broken line arrow in FIG. It is like that.

  Thereby, the linear motion shaft 13 and the rotation shaft 15 are displaced to a first position shown in FIG. 12, a second position shown in FIG. 13, and a third position shown in FIG. The first position shown in FIG. 12 is a position where the sliding portion 132 is slid the most on the left side on the slide base 118, and the rotation shaft 15 is the most protruding state on the left side of the housing body 11B. Further, in this first position, the rotation shaft 15 rotates about the first axis X1, so that the lid locking portion 15B becomes the unlatched position. At this unlatched position, the lid locking portion 15B extends in the up-down direction.

  The second position shown in FIG. 13 is a position where the sliding portion 132 slides to the right on the slide base 118 from the first position, and the rotation shaft 15 is pushed into the right side of the housing body 11B compared to the first position. It is a state that has been. The third position shown in FIG. 14 is a position where the sliding portion 132 is slid the most on the right side on the slide base 118, and the rotation shaft 15 is further pushed to the right side of the housing body 11B than the second position. It is. In the second position and the third position, the rotation shaft 15 rotates about the first axis X1, so that the lid locking portion 15B becomes the latch position. At this latch position, the lid locking portion 15B extends in the front-rear direction (see FIG. 3).

  Moreover, as shown to (A) of FIG. 12, said coil spring 27 is attached in the accommodating part 11C. The left end of the coil spring 27 is locked to the housing body 11B, and the right end is locked to the spring locking portion 131 of the base portion 13B. Thereby, as shown in FIG. 12, the linear motion shaft 13 and the rotation shaft 15 are biased toward the first position by the biasing force of the coil spring 27.

  The switch 21 is disposed below the linear motion shaft 13 in the accommodating portion 11C. At this time, the switch 21 exposes the contact portion 21B on the slide base 118 as shown in FIG. Further, by arranging the switch 21 in the accommodating portion 11C, as shown in FIG. 6, the other ends of the third and fourth electrodes 23C and 23D are arranged in the connector portion 112C.

  As shown in FIG. 12, the lock device 19 is disposed in the lower part in the accommodating portion 11 </ b> C. More specifically, the electric motor 19A and the worm gear 19B are disposed at the lowermost portion in the accommodating portion 11C. The worm wheel 19C is swingably attached to the shaft portion 117 shown in FIG. 7 in a state where it is engaged with the worm gear 19B. Thereby, the connecting shaft 191 is disposed so as to be coaxial with the shaft portion 117. The worm wheel 19C is swingable around the fourth axis X4 with the axis of the shaft 117 and the axis of the connecting shaft 191 as the fourth axis X4. At this time, the swing range is regulated by the worm wheel 19C coming into contact with a stopper member 37 (see FIG. 7) provided in the housing portion 11C. Thus, the worm wheel 19C can be displaced between the unlock position shown in FIGS. 12 and 14 and the lock position shown in FIG. The fourth axis X4 is parallel to the second and third axes X2 and X3.

  As described above, after the linear motion shaft 13 and the like are attached to the housing body 11B, as shown in FIG. 7, the cover 11A is attached to the housing body 11B. At this time, the connecting shaft 191 of the worm wheel 19C passes through the communication hole 111 of the cover 11A and protrudes from the outer surface of the cover 11A. And the release operation part 31 is attached to the connection shaft 191 from the outer surface side of the cover 11A so that rocking | fluctuation is possible. Thereby, as shown by the white arrow of FIG. 15, the cancellation | release operation part 31 can rock | fluctuate around the 4th axis X4. Thus, the apparatus main body 10A is completed. The release operation unit 31 is connected to a string or the like (not shown). Here, in a state where the release operation unit 31 is not operated, the strings and the like are covered with a trim cover (not shown) in the passenger compartment CR.

  As shown in FIG. 5, the slide restricting mechanism 10 </ b> B includes a base member 51, a detection lever 53, a second torsion coil spring 55, a first connecting pin 57, a restricting portion 59, and an inner cable 61.

An insertion hole 530 is formed in the central portion 53A. In addition, a first cable connection portion 531 is formed at the second tip portion 53C. The second torsion coil spring 55 includes a second coil portion 55A, a third arm portion 55B, and a fourth arm portion 55C. The third arm portion 55B extends rightward from the second coil portion 55A. The fourth arm portion 55C extends leftward from the second coil portion 55A.

  The detection lever 53 and the second torsion coil spring 55 are connected to the base member 51 from the front of the base member 51 by a first connecting pin 57. Specifically, the first connecting pin 57 is inserted into the insertion hole 530 of the detection lever 53 and the insertion hole 51 </ b> A of the base member 51 while being inserted into the second coil portion 55 </ b> A of the second torsion coil spring 55. Yes. Accordingly, as shown in FIGS. 12 to 14 and the like, the detection lever 53 can swing around the fifth axis X5 with the axis of the first connecting pin 57 as the fifth axis X5. As shown in FIG. 15, in the second torsion coil spring 55, the third arm portion 55 </ b> B is locked to the spring locking portion 51 </ b> B of the base member 51, and the fourth arm portion 55 </ b> C is the second of the detection lever 53. Locked to the tip 53C. Furthermore, one end of the inner cable 61 is connected to the first cable connection portion 531. Details of the swing of the detection lever 53 will be described later.

  As shown in FIG. 17, the restricting portion 59 has a bracket 59A, a restricting lever 59B, a connection plate 59C, a third torsion coil spring 59D, and a second connecting pin 59E.

  The bracket 59A is formed along the shape of the left side of the vehicle body 1A and extends in the front-rear direction. In addition to the insertion hole 590 formed in the bracket 59A, a spring locking portion 591 is formed. The bracket 59A is formed with fixing holes 592A and 592B for fixing to the vehicle body 1A.

  The regulating lever 59B is formed in a substantially triangular shape. An insertion hole 593 is formed at the upper end of the restriction lever 59B. In the connection plate 59C, an insertion hole 594 is formed, and a second cable connection portion 595 is formed. The connection plate 59C is formed with a locking piece 596 extending in the right direction. The connection plate 59C is integrated with the regulation lever 59B by the latching piece 596 being latched by the regulation lever 59B.

  The third torsion coil spring 59D includes a third coil part 597, a fifth arm part 598, and a sixth arm part 599. The fifth arm portion 598 extends rearward from the third coil portion 597. The sixth arm part 599 extends downward from the third coil part 597.

  The restriction lever 59B, the connection plate 59C, and the third torsion coil spring 59D are coupled to the left side of the bracket 59A by the second coupling pin 59D. Specifically, the second connecting pin 59E is inserted through the third coil portion 597 of the third torsion coil spring 59D, the insertion hole 594 of the connection plate 59C, the insertion hole 593 of the restriction lever 59B, and the insertion of the bracket 59A. The hole 590 is inserted. As a result, as shown in FIG. 5, the regulating lever 59B, together with the connection plate 59C, has the axis of the second connecting pin 59E as the sixth axis X6, and the allowable position D7 and the regulating position D8 around the sixth axis X6. Can swing between the two.

  Further, the other end of the inner cable 61 is connected to the second cable connection portion 595. Thereby, the detection lever 53, the control lever 59B, and the connection plate 59C are connected. Therefore, in accordance with the swing of the detection lever 53, the regulation lever 59B and the connection plate 59C swing around the sixth axis X6 as described above. Then, the regulating lever 59B is displaced to the permissible position D7, so that the regulating lever 59B extends substantially in the front-rear direction, that is, substantially parallel to the bracket 59A. On the other hand, the restricting lever 59B is displaced to the restricting position D8, so that the restricting lever 59B extends in the vertical direction and stands up with respect to the bracket 59A.

  As shown in FIG. 15, the slide regulating mechanism 10 </ b> B is attached to the apparatus main body 10 </ b> A when the base member 51 is fixed to the housing 11. Specifically, the base member 51 is attached to the outer surface of the cover 11 </ b> A, that is, the front surface of the housing 11 by means of attachment screws 63 </ b> A and 63 </ b> B. At this time, as indicated by an arrow in the figure, a part of the first tip portion 53B of the detection lever 53 enters the accommodating portion 11C from the slit 110 of the cover 11A. Thereby, as shown in FIGS. 12-14, the 1st front-end | tip part 53B is hold | maintained at the holding | maintenance part 13C of the linear motion shaft 13 within the accommodating part 11C. That is, the detection lever 53 is positioned on the outer surface of the cover 11A together with the base member 51 except for a part of the first tip portion 53B.

  Further, by attaching the base member 51 to the front surface of the housing 11, the fifth axis X5 is parallel to the second to fourth axes X2 to X4. Then, the detection lever 53 swings between the non-detection position D5 and the detection position D6 around the fifth axis X5. Here, the detection lever 53 is urged toward the non-detection position D5 by the urging force of the second torsion coil spring 55 as shown in FIG. Thus, the lid opening / closing device 10 is completed.

  In the lid opening / closing device 10, as shown in FIGS. 3 and 4, the device main body 10 </ b> A is attached to the vehicle body 1 </ b> A and is disposed between the opening 3 and the lid 5. More specifically, the apparatus main body 10 </ b> A is attached to the opening 3 by fixing the fixing portion 113 shown in FIG. 6 with a bolt (not shown). Thereby, as shown in FIGS. 3 and 4, in the apparatus main body 10 </ b> A, the housing 11 is disposed inside the vehicle body 1 </ b> A inside the opening 3, and the rotating shaft 15 is protruded into the opening 3. It has become. In the apparatus main body 10A, the switch 21 and the electric motor 19A are connected to a control device (not shown) provided in the vehicle body 1A through the connector portion 112.

On the other hand, as shown in FIGS. 1 and 2, with respect to the restricting portion 59, the bracket 59A is fixed at a predetermined position in the vicinity of the slide door 7 in the vehicle body 1A. At this time, the bracket 59A is fixed to the vehicle body 1A so that the sixth axis X6 extends in the left-right direction. That means
The sixth axis X6 is parallel to the first axis X1. Thus, the restricting portion 59 is disposed on the vehicle body 1A in the vicinity of the slide door 7.

  The lid opening / closing device 10 operates as follows to hold the lid 5 in the closed state shown in FIGS. 1 and 3 and open the lid 5 as shown in FIGS. 2 and 4. To change. Further, as shown in FIG. 2, the lid opening / closing device 10 prevents interference between the slide door 7 and the lid 5 in the open position. First, the case where the cover body 5 in an open state is held in a closed state will be specifically described.

  In the state where the lid 5 is in the open position, the linear motion shaft 13 and the rotation shaft 15 are located at the first position by the urging force of the coil spring 27 as shown in FIG. At this time, as shown in FIG. 5B, the guided portion 37 fixed to the base portion 13B of the linear motion shaft 13 is located at the first connection portion 173 in the opening / closing profile 17C. Further, since the linear motion shaft 13 is in the first position, the slide portion 132 of the base portion 13B presses the contact portion 21B of the switch 21. Thereby, in the switch 21, the contact portion 21 </ b> B is pushed into the switch body 21 and is turned on. For this reason, the control device detects that the lid 5 is in an open state, and performs each control of the automobile 1 in accordance with this.

  Further, in the state where the linear motion shaft 13 and the rotation shaft 15 are in the first position, as shown in FIG. 12A, the worm wheel 19 is rotated in the direction of the solid line arrow and becomes the unlock position. ing.

  Then, as the lid 5 in the open position is displaced toward the closed position by the user or the like, the lid locking portion 15B is locked from the entrance 5C of the locked portion 5B in the rotating shaft 15. Gradually enter the portion 5B (see FIG. 3B). At this time, the rotating shaft 15 is pressed by the lid 5 that is displaced toward the closed position. For this reason, as shown by the solid line arrow in the figure, the rotation shaft 15 is displaced rightward from the first position together with the linear movement shaft 13. Note that the state illustrated in FIG. 3B is a state in which the lid locking portion 15B has completely entered the locked portion 5B.

  Thus, when the lid body 5 is displaced from the open position to the closed position, as shown in FIG. 13A, the linear movement shaft 13 and the rotation shaft 15 are displaced to the second position. Further, when displacing to the second position, the rotation shaft 15 rotates around the first axis X1 in the direction of the broken line arrow shown in FIG. For this reason, the lid locking portion 15B is displaced to the latch position. Thereby, in the state in which the rotation shaft 15 is displaced to the second position, the lid locking portion 15B is locked in the locked portion 5B and cannot escape from the entrance 5C.

  Further, when the linear motion shaft 13 is displaced from the first position to the second position, the guided portion 37 is detached from the first connection portion 173 and the first profile 171 is moved as shown in FIG. Move to the right. Here, since the through lever 39 is biased in the direction D3 by the first torsion coil spring 25, the lower end side of the through lever 39 covers a part of the second profile 172. When the through lever 39 is in this state, the through lever 39 will not be displaced in the D4 direction even if the guided portion 37 that has detached the first connection portion 173 contacts the through lever 39 from below. For this reason, the guided portion 37 detached from the first connection portion 173 does not move on the second profile 172 side.

  The heart cam 17 swings in the direction D2 around the second axis X2 while resisting the biasing force of the first torsion coil spring 25, and guides the guided portion 37 from the first profile 171 to the second connecting portion 174. To do. Thus, by positioning the guided portion 37 at the second connection portion 174, the opening / closing profile 17C restricts the linear motion shaft 13 and the rotation shaft 15 from returning from the second position to the first position. For this reason, the linear motion shaft 13 and the rotation shaft 15 maintain the second position. After guiding the guided portion 37 to the second connection portion 174, the heart cam 17 is urged again in the direction D1 by the urging force of the first torsion coil spring 25.

  Thus, when the linear motion shaft 13 and the rotation shaft 15 maintain the second position, the lid locking portion 15B maintains the latch position as shown in FIG. 3B. For this reason, in the apparatus main body 10A, the rotating shaft 15 holds the lid body 5 in the closed position, and the lid body 5 is prohibited from being displaced from the closed position to the open position.

  Further, when the linear motion shaft 13 is displaced to the second position, the slide portion 132 does not press the contact portion 21B of the switch 21. As a result, the switch 21 is turned off. For this reason, the control device detects that the lid 5 is in the closed state, and performs each control of the automobile 1 according to this.

  Moreover, in this lid body opening / closing device 10, the control device performs power supply to the electric motor 19A when a user or the like performs a locking operation from the inside of the passenger compartment CR or the like while the lid body 5 is held in the closed position. . For this reason, the electric motor 19A operates to drive the worm gear 19B to rotate. For this reason, as shown in FIG. 13A, the worm wheel 19C meshing with the worm gear 19B rotates in the direction of the solid arrow around the fourth axis X4 and is displaced to the lock position. As a result, the action portion 190 faces the contact piece 17B of the heart cam 17 in the accommodating portion 11C. Here, in the lid opening / closing device 10, when the electric motor 19 </ b> A is used, the worm wheel 19 </ b> C rotates independently of the release operation unit 31. For this reason, even if the worm wheel 19C is displaced to the locked position as described above, the release operation portion 31 does not swing around the fourth axis X4.

  Thus, in the state where the worm wheel 19C is in the locked position, even if the heart cam 17 further tries to swing in the D1 direction, the contact piece 17B contacts the action portion 190, and the heart cam 17 swings in the D1 direction. Be regulated. Thus, in the lid opening / closing device 10, the guided portion 37 cannot be detached from the second connection portion 174, and the linear motion shaft 13 and the rotation shaft 15 are returned from the second position to the first position. Are reliably regulated. For this reason, in this lid body opening / closing apparatus 10, it becomes possible to more reliably inhibit the lid body 5 from being displaced from the closed position to the open position by performing a locking operation by a user or the like.

  Further, in the lid opening / closing device 10, the first distal end portion 53 </ b> B is pressed against the linear motion shaft 13 in the detection lever 53 by the displacement of the linear motion shaft 13 and the rotation shaft 15 from the first position to the second position. Is done. For this reason, the 1st front-end | tip part 53B rotates rightward within the accommodating part 11C against the urging | biasing force of the 2nd torsion coil spring 55. FIG. As a result, the detection lever 53 is displaced to the detection position D6 as indicated by a broken line arrow.

  When the detection lever 53 is displaced to the detection position D6, the second distal end portion 53C rotates upward on the outside of the cover 11A. Then, as shown in FIG. 5, the displacement of the detection lever 53 to the detection position D <b> 6 is transmitted to the restricting portion 59 by the inner cable 61. For this reason, in the restricting portion 59, the restricting lever 59B swings around the sixth axis X6 and is displaced to the allowable position D7.

  Thus, when the user or the like operates the slide door 7 in a state where the lid 5 is held in the closed position, as shown in FIG. It moves on the rail to the rear of the vehicle body 1A while passing below. For this reason, the user or the like can displace the slide door 7 to the cover position.

  On the other hand, when the lid 5 in the closed state is displaced to the open state, first, when the lock operation is performed as described above, the lock release operation is performed. As a result, the electric motor 19A operates in the opposite direction to the case where the locking operation is performed, and the worm wheel 19C rotates in the direction of the solid arrow around the fourth axis X4 as shown in FIG. Displaces to unlock position.

  When the worm wheel 19C is displaced to the unlock position, the action portion 190 is separated from the contact piece 17B of the heart cam 17 in the housing portion 11C. For this reason, the swing in the direction D1 in the heart cam 17 is allowed.

  Here, in the lid opening / closing device 10, the user or the like swings the release operation unit 31 through a string or the like connected to the release operation unit 31, so that it does not depend on the operation of the electric motor 19 </ b> A as described above. It is also possible to displace the worm wheel 19C to the unlock position. Thus, when the release operation unit 31 is swung, the worm wheel 19C is displaced to the unlock position in conjunction with the swing of the release operation unit 31.

  Then, in the state where the swing in the direction D1 of the heart cam 17 is allowed as described above, the user or the like presses the lid 5 in the closed state from the left side of the vehicle body as shown in FIG. As a result, as shown by the phantom lines in the figure, the rear of the lid 5 is pushed to the right of the vehicle body 1A from the closed position, and the lid 5 is displaced to the pushed position.

  When the lid body 5 is displaced to the pushing position, the rotation shaft 15 is further pressed by the lid body 5 together with the linear motion shaft 13 and is further displaced rightward from the second position. For this reason, as shown in FIG. 14A, the linear movement shaft 13 and the rotation shaft 15 are displaced from the second position to the third position. Here, the linear movement shaft 13 is displaced to the third position, so that the contact portion 132 </ b> A contacts the slide stopper 118. For this reason, the linear motion shaft 13 is restricted from being displaced further to the right beyond the third position.

  Further, when the linear motion shaft 13 and the rotation shaft 15 are displaced to the third position, the first tip 53B is further pressed against the linear motion shaft 13 in the detection lever 53. For this reason, the 1st front-end | tip part 53B rotates further on the right side within the accommodating part 11C against the urging | biasing force of the 2nd torsion coil spring 55. FIG. As a result, the second distal end portion 53C further rotates upward outside the cover 11A. That is, the detection lever 53 maintains the detection position D6 in a state where the lid body 5 is displaced to the pushing position.

  Then, when the linear motion shaft 13 and the rotation shaft 15 are displaced to the third position, the guided portion 37 is detached from the second connection portion 174 and the second profile 172 as shown in FIG. Move to the right side of At this time, the heart cam 17 swings around the second axis X 2 and guides the guided portion 37 from the second connection portion 174 to the second profile 172. Thereby, the opening / closing profile 17C allows the linear motion shaft 13 and the rotation shaft 15 to return from the third position to the first position through the second position.

  For this reason, as shown in FIG. 12A, the linear motion shaft 13 and the rotation shaft 15 are returned to the first position by the urging force of the coil spring 27. At this time, the heart cam 17 moves the guided portion 37 from the right side to the left side of the second profile 172 while swinging in the direction D2. Then, as shown in FIG. 11, the guided portion 37 that moves the second profile 172 is pressed against the through lever 39 so that the through lever 39 resists the biasing force of the first torsion coil spring 25. Displacement in the D4 direction. Thereby, the lower end side of the through lever 39 does not cover the second profile 172. For this reason, the guided portion 37 can move from the second profile 172 to the first connection portion 173.

  Then, by returning to the first position, the rotation shaft 15 presses the lid 5 to the left in the locked portion 5B. For this reason, as shown in FIG. 4, the lid 5 is displaced to the open position. Further, by returning to the first position, the rotation shaft 15 rotates in the direction of the broken arrow around the first axis X1 as shown in FIG. 4B. For this reason, the lid locking portion 15B is displaced to the unlatched position. Thereby, the state in which the lid locking portion 15B is locked in the locked portion 5B is released. For this reason, the lid locking portion 15B can escape from the entrance 5C when the lid 5 is displaced to the open position. Thus, the user or the like can perform a refueling operation on the automobile 1 through the refueling port 9.

  Further, in the lid opening / closing device 10, as shown in FIG. 12A, when the linear motion shaft 13 and the rotation shaft 15 are returned to the first position, the detection lever 53 is moved to the second torsion coil spring 55. Is displaced to the non-detection position D5 as indicated by the broken line arrow. For this reason, the first tip portion 53B rotates to the left in the accommodating portion 11C while following the linear motion shaft 13. On the other hand, the second tip portion 53C rotates downward on the outside of the cover 11A. For this reason, as shown in FIG. 5, the inner cable 61 is pulled by the detection lever 53, and in the restriction part 59, the restriction lever 59B swings around the sixth axis X6 and is displaced to the restriction position D8.

  For this reason, as shown in FIG. 2, in a state where the lid 5 is displaced to the open position, if the user or the like operates the slide door 7, the slide door 7 is displaced to a certain extent to the rear, and the passenger compartment CR The support shaft 7A comes into contact with the regulating lever 59B when the lever is opened to a certain extent. For this reason, the slide door 7 cannot be displaced further rearward and cannot be displaced to the cover position as shown in FIG. This prevents the lid opening / closing device 10 from interfering with the sliding door 7 and the lid 5 in the open position during the refueling operation for the automobile 1.

  Thus, the structure of the lid opening / closing device 10 is simplified as compared with the conventional lid opening / closing device. For this reason, in this lid body opening / closing device 10, it is possible to hold the lid body 5 in the closed position and to displace the lid body 5 to the open position even if the accuracy of each component and assembly is not so high. It has become. For this reason, in this lid body opening / closing device 10, strict quality control is not necessarily required at the time of manufacture of each component and assembly of each component. Moreover, in this lid body opening / closing apparatus 10, since it is difficult for the parts to slide or collide with each other as compared with the conventional lid body opening / closing apparatus, even if the lid body 5 is repeatedly opened and closed, Wear or chipping is less likely to occur.

  Therefore, in the lid opening / closing device 10 of the embodiment, the manufacturing cost can be reduced and the durability can be improved.

  In the lid opening / closing device 10, a through lever 39 is provided on the heart cam 17. The through lever 39 swings in the direction D4 when it comes into contact with the guided portion 37 that is going from the second profile 172 toward the first connection portion 173, while the through lever 39 moves from the first connection portion 173 toward the second profile 172. Even if it comes into contact with the guided portion 37 to be covered, it does not swing in the D4 direction. For this reason, as shown by the arrows in FIGS. 10 and 11, the guided portion 37 has an opening / closing profile 17 </ b> C only in the circulation direction of the first connection portion 173, the first profile 171, the second connection portion 174, and the second profile 172. And circulating the opening / closing profile 17C in a direction opposite to the circulation direction is reliably restricted. Therefore, in the lid opening / closing device 10, the lid 5 can be reliably locked and released by the lid locking portion 15 </ b> B of the rotating shaft 15.

  Further, in the lid opening / closing device 10, since the apparatus main body 10A includes the switch 21, the control device determines whether the lid 5 is in the open position depending on whether the switch 21 is in the OFF state or the ON state. It is possible to detect this. For this reason, the control device can perform each control of the automobile 1 according to the state of the lid 5. Further, by providing the switch 21 in the housing 11 as a unit, it is possible to prevent the cover opening / closing device 10 from being complicated and large.

  In the lid opening / closing device 10, the worm wheel 19 </ b> C can also be displaced to the unlock position by swinging the release operation unit 31. For this reason, even if the electric motor 19A does not operate due to an insufficient storage amount of the battery provided in the vehicle body 1A, the worm wheel 19C can be displaced to the unlock position, and the heart cam 17 moves in the D1 direction. The regulation of swinging can be released.

  Further, in the lid opening / closing device 10, a slide restricting mechanism 10B is attached to the device main body 10A. Thereby, in this lid body opening / closing apparatus 10, as described above, the displacement of the slide door 7 to the cover position in a state where the lid body 5 is in the open position can be restricted. Interference with the body 5 can be prevented.

  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 device main body 10A of the lid opening / closing device 10 holds the lid 5 of the opening 3 in the closed position or displaces it to the open position. A lid such as a power supply port or a glove box may be held in a closed position or displaced to an open position. Further, the slide member is not limited to the slide door 7, and the slide restriction mechanism 10 </ b> B may prevent other slide members from interfering with the lid 5.

  Furthermore, you may comprise the cover body opening / closing apparatus 10 of an Example only by apparatus main body 10A. In this case, the lid opening / closing device 10 can be used not only for a vehicle that does not have a sliding member such as the sliding door 7 but also for a vehicle in which interference between the sliding member and the lid 5 is not a problem. Moreover, the manufacturing cost of the lid body opening / closing device 10 can be further reduced by configuring only the device main body 10A.

  Further, instead of the switch 21, when the linear motion shaft 13 is in the first position, the first state is the first ON state, and when the linear motion shaft 13 is in the second position or the third position. May adopt a switch that is in the second ON state as the second state.

  In the embodiment, the guided portion 37 is fixed to the base portion 13 of the linear motion shaft 13. However, the present invention is not limited to this, and when the linear motion shaft 13 reciprocates in the left-right direction, the guided portion 37 swings in the vertical direction, so that the guided portion 37 circulates through the opening / closing profile 17C. .

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