Description

  The present invention relates to a vehicle door lock device.

  Conventionally, as a door lock device for vehicles, what was indicated, for example in patent documents 1 is known. This vehicle door lock device is integrally provided with a release function and a closer function, and the active lever rotation regulation range relating to these functions includes a neutral region (neutral range), a closed region, and a release region. It is divided into. Then, the active lever is rotated in one direction from the neutral region toward the closed position which is the tip of the rotation regulation range (closed region) so as to hold the door in the half door state in the fully closed state. Activate the latch mechanism. On the other hand, the active lever is latched so as to release the door in the fully closed state by rotating in the other direction from the neutral region toward the release position which is the other end side of the rotation regulation range (release region). Activate the mechanism.

  In addition, the vehicle door lock device includes a neutral switch that detects that the active lever is in the neutral region, and a neutral switch lever that is coupled so as to rotate integrally with the operation shaft of the neutral switch. It suffices that the active lever in the closed region can be detected as being in that region. For this reason, the active lever basically engages the first gear portion with the second gear portion of the neutral switch lever to rotate the neutral switch lever, but when the active lever reaches the closed region, the first cam portion Slide the neutral switch lever to the second cam to stop and position the neutral switch lever.

Japanese Patent Laid-Open No. 2006-98612

  By the way, the distance between the parallel axes of the active lever and the neutral switch lever (so-called inter-axis pitch) is, by design, the radius of the pitch circle of the first gear portion and the radius of the pitch circle of the second gear portion. It is set slightly longer than the total length. This is because the neutral switch lever made of a resin material is easily expanded and contracted by the temperature under the operating environment (for example, −30 ° C. to 80 ° C.) with respect to the active lever made of a metal plate. This is because it is necessary to set a gap (hereinafter also referred to as “initial gap”) in consideration of the dimension when the component (neutral switch lever) extends to the maximum extent in addition to the variation in attachment.

  Therefore, for example, when such an initial gap is maximized, there is a meshing misalignment in which the first gear portion and the second gear portion cannot mesh with each other at a normal position, and interference between the first gear portion and the second gear portion. May occur.

  Specifically, as shown in FIG. 12A, when the active lever 100 in the closed region rotates in the direction toward the neutral region (counterclockwise rotation direction in the drawing), the first cam portion 101 of the active lever 100 is used. Further, when the first gear portion 102 of the active lever 100 and the second gear portion 107 of the neutral switch lever 105 are to be engaged from the sliding state of the second cam portion 106 of the neutral switch lever 105, the neutral switch is equivalent to the initial gap. If the rotation of the lever 105 is delayed, the first gear portion 102 and the second gear portion 107 may not be able to mesh with each other due to displacement.

  Alternatively, as shown in FIG. 12B, when the active lever 100 in the closed region rotates in the direction toward the neutral region (counterclockwise rotation direction in the drawing), the first cam portion 101 and the neutral switch of the active lever 100 When the first gear portion 102 of the active lever 100 and the second gear portion 107 of the neutral switch lever 105 are about to mesh from the sliding state of the second cam portion 106 of the lever 105, the neutral switch lever 105 is moved by the initial gap. When the rotation is advanced, the second gear portion 107 may ride on the first gear portion 102.

  An object of the present invention is to provide a vehicle door lock device that can further stabilize the transition to a meshing state with a neutral detection lever when an operating lever in a closed region rotates in a direction toward a neutral region. .

  In the vehicle door lock device that solves the above-described problems, a first gear portion and a first arcuate surface that extends in the first circumferential direction are formed on the outer circumferential side along a first circumferential direction that is a circumferential direction around a support shaft. The first cam portion is provided, and the door in the half-door state is fully closed by rotating from the neutral region of the rotation defining range around the support shaft toward the closed position which is the front end side of the closed region. An operating lever that is held in a state and is connected so as to rotate around an operation shaft parallel to the support shaft, and is arranged on the outer peripheral portion along the second circumferential direction, which is a circumferential direction around the operation shaft. When the second gear portion meshable with one gear portion and the first arc surface can be brought into contact with the rotation of the actuating lever toward the closed position and are in contact with the first arc surface Having a second cam portion formed with a second arc surface extending in the first circumferential direction. A neutral detection lever that is disposed at a boundary portion between the first gear portion and the first cam portion, and the second lever portion side in the second circumferential direction of the second cam portion. An engagement groove into which an engagement end portion that is a tip portion of the engagement portion can be engaged is formed, and the engagement of the engagement end portion into the engagement groove causes the first arc surface and the second arc surface to be engaged. The first arc portion is switched to the meshing state of the first gear portion and the second gear portion, and the first arc surface has a virtual arc extending from the second arc surface to the engagement end portion. An extension portion that enters a rotation trajectory of the surface is formed, and the extension portion rotates between the second arc surface of the second cam portion and the engagement end portion in the second circumferential direction. A notch that opens the locus is formed.

  According to this configuration, when the operating lever rotates within the specified rotation range, if the first gear portion and the second gear portion are in the meshing state, the rotation direction according to the rotation direction is determined. The neutral detection lever rotates around the operation shaft. Further, when the first arc surface and the second arc surface are brought into contact with the rotation of the operation lever toward the close position, the neutral detection lever moves the operation shaft on the second arc surface. The first arc surface protrudes inward in the radial direction as the center, and thus the rotation is restricted. On the other hand, the actuating lever is rotatable with respect to the neutral detection lever by sliding the first arc surface on the second arc surface. Therefore, the operating lever can be rotated toward the closed position while sliding the first arc surface on the second arc surface with the neutral detection lever remaining. The actuating lever in the closed region can be rotated toward the neutral region while sliding the first arc surface on the second arc surface while leaving the neutral detection lever. At this time, the rotation of the neutral detection lever in one direction is restricted to a range until the engagement end portion comes into contact with the first cam portion unless the extension portion passes through the engagement end portion. . As described above, since the posture of the neutral detection lever is further stabilized, the engagement end portion can be more smoothly engaged with the engagement groove that has reached the engagement end portion. The shift to the meshing state of the gear part and the second gear part can be further stabilized. Moreover, the rotation locus | trajectory of the said extension part at this time can suppress the interference of a said 1st cam part and a said 2nd cam part because it is open | released by the said notch.

  In the vehicle door lock device, the distal end portion of the engagement end portion that is separated from the operation shaft protrudes and forms an engagement end surface that is shaped in the engagement end portion that extends the second arc surface. Preferably, the engagement groove is formed with a relief groove that opens a rotation locus of the engagement end surface.

  According to this configuration, when the operating lever in the closed region rotates toward the neutral region while sliding the first arc surface on the second arc surface while leaving the neutral detection lever left, The rotation of the neutral detection lever in one direction is further restricted by approaching the first cam portion (first arc surface) by the amount of protrusion of the engagement end surface. In this way, the posture of the neutral detection lever is further stabilized, so that the engagement end can be more smoothly engaged in the engagement groove that has reached the engagement end, and the first Transition to the meshing state of the gear part and the second gear part can be further stabilized. Moreover, the rotation locus | trajectory of the said engagement end surface at this time is open | released by the said escape groove, and can suppress the interference of the said engagement end part and the said engagement groove | channel.

  In the vehicle door lock device, the neutral detection lever is configured to suppress separation of the engagement end portion from the first cam portion when the first arc surface and the second arc surface are in contact with each other. It is preferable to provide a position restricting portion for restricting the rotational position.

  According to this configuration, when the first arcuate surface and the second arcuate surface are in contact with each other, the position restricting portion suppresses the separation of the engagement end portion from the first cam portion. The rotational position of the neutral detection lever is limited. Therefore, when the operating lever in the closed region rotates toward the neutral region while sliding the first circular arc surface on the second circular arc surface while leaving the neutral detection lever, the neutral detection lever Rotation in the opposite direction is suppressed by the position limiting unit. In this way, the posture of the neutral detection lever is further stabilized, so that the engagement end can be more smoothly engaged in the engagement groove that has reached the engagement end, and the first Transition to the meshing state of the gear part and the second gear part can be further stabilized.

  In the vehicle door lock device that solves the above-described problems, a first gear portion and a first arcuate surface that extends in the first circumferential direction are formed on the outer circumferential side along a first circumferential direction that is a circumferential direction around a support shaft. The first cam portion is provided, and the door in the half-door state is fully closed by rotating from the neutral region of the rotation defining range around the support shaft toward the closed position which is the front end side of the closed region. An operating lever that releases the door in the fully closed state by rotating in the other direction from the neutral region toward the release position that is the tip side of the release region, and parallel to the support shaft A second gear portion that is coupled to rotate about a manipulation shaft, and that can be meshed with the first gear portion on an outer peripheral side by side in a second circumferential direction that is a circumferential direction around the manipulation shaft; With the rotation of the actuating lever toward the closed position A neutral detection lever having a second cam portion formed with a second arcuate surface that can contact the first arcuate surface and extends in the first circumferential direction when in contact with the first arcuate surface; The actuating lever is disposed at a boundary portion between the first gear portion and the first cam portion, and is a tip portion on the second gear portion side in the second circumferential direction of the second cam portion. An engagement groove into which the engagement end portion can be engaged is formed, and the engagement state of the first arc surface and the second arc surface after the engagement end portion is engaged with the engagement groove. The first gear part and the second gear part are switched to the meshing state, and the first arcuate surface has a virtual arcuate surface trajectory extending from the second arcuate surface to the engagement end. The second arcuate surface of the second cam portion and the engagement in the second circumferential direction. Between the parts, notch opens the rotational locus of the extension portion.

  The present invention has an effect of further stabilizing the transition to the meshing state with the neutral detection lever when the operating lever in the closed region rotates in the direction toward the neutral region.

  Hereinafter, an embodiment of a vehicle door lock device will be described. Hereinafter, the front-rear direction of the vehicle is referred to as “front-rear direction”, and the upper direction and the lower direction of the vehicle height are referred to as “upward” and “lower”, respectively.

  As shown in FIG. 1, a sliding door 10 as a door supported on a side portion of a vehicle body via an appropriate support member (not shown) is formed on the boarding / alighting formed on the body as it moves in the front-rear direction. Open and close the opening. In this slide door 10, the fully closed door lock device 11 that holds the slide door 10 in a fully closed state by engaging with the body side and the slide door 10 are held in a fully closed state or a half door state (closed state). A closer release device 12 is installed, and a fully open door lock device 13 is installed to hold the slide door 10 in a fully open state by engaging with the body side.

  The closer / release device 12 electrically closes the sliding door 10 in the half-door state to the fully closed state. The closer / release device 12 is mechanically linked to an appropriate remote controller (remote controller) 14 installed in the slide door 10 via a release cable C1, and is connected to the remote controller 14 via an open cable C2. It is mechanically linked. The closer / release device 12 releases the holding of the slide door 10 in the fully closed state by transmitting the electrically operated release operation force via the release cable C1, the remote controller 14, and the open cable C2.

  The remote controller 14 is connected to an operation handle 15 exposed on the outer surface or inner surface of the slide door 10, and the closer / release device 12 receives the manual release operation force of the operation handle 15 via the open cable C2. In this manner, the holding of the sliding door 10 in the fully closed state is similarly released.

  The remote controller 14 is mechanically linked to the fully-closed door lock device 11 and the fully-open door lock device 13 via open cables C3 and C4, respectively. 15 manual release operation forces are transmitted to the fully closed door lock device 11 and the fully open door lock device 13. At this time, the fully closed door lock device 11 releases the holding of the slide door 10 in the fully closed state, or the fully open door lock device 13 releases the holding of the slide door 10 in the fully opened state.

  As shown in FIG. 2, the closer / release device 12 has a base plate 21 made of, for example, a metal plate, which extends along the rear end surface of the sliding door 10 and is fastened thereto, and a latch installed on the base plate 21. It has a mechanism 22. The latch mechanism 22 includes a latch 25 and a pole 26 that are connected to a pair of parallel rotating shafts 23 and 24 that are pivotally supported by the base plate 21 so as to integrally rotate.

  The latch 25 is formed with a substantially U-shaped engaging recess 25a. And the latch 25 forms the 1st nail | claw part 25b and the 2nd nail | claw part 25c on the one side and the other side (a counterclockwise rotation direction and the clockwise rotation direction side in FIG. 2) on both sides of the engagement recessed part 25a. . The latch 25 forms a third claw portion 25d that protrudes from the middle portion in the longitudinal direction of the first claw portion 25b. In the circumferential direction, the end surface of the tip end portion of the first claw portion 25b facing the second claw portion 25c and the end surface of the third claw portion 25d facing the first claw portion 25b are the full latch engagement surface 25e and the half latch engagement. Each of the surfaces 25f is formed. The latch 25 is urged toward the side rotating in the clockwise direction in the figure when the other end of a latch urging spring (not shown) with one end hooked to the base plate 21 is hooked. 21 is abutted against a latch stopper (not shown) installed at 21 to restrict the rotation in this direction and is held at a predetermined initial rotation position (hereinafter referred to as “unlatch position”). Note that the latch 25 projects an arm-like interlocking piece 25g on the opposite side of the third claw portion 25d with the rotation shaft 23 interposed therebetween.

  On the other hand, the pole 26 forms a substantially claw-like engaging portion 26a extending from the rotating shaft 24 to one side in the radial direction (left side in FIG. 2). The pole 26 is urged by a pole urging spring (not shown) to turn in the counterclockwise direction in the figure, that is, the side to move the engaging portion 26a to the lower side in the figure and to a predetermined initial turning position. Retained.

Here, the basic operation of the latch mechanism 22 will be described.
In the state where the slide door 10 is opened, the latch 25 held at the unlatched position makes the engaging recess 25a face the striker 29 fixed to the body. That is, the engagement recess 25 a opens the entry path of the striker 29 that accompanies the closing operation of the slide door 10. Further, the pole 26 held at a predetermined initial rotation position has the engaging portion 26a disposed above the third claw portion 25d. The state of the latch mechanism 22 at this time is referred to as an unlatched state (release state).

  Next, it is assumed that the striker 29 has entered the engagement recess 25a as the slide door 10 is closed. At this time, the striker 29 presses the inner wall surface of the engaging recess 25a, so that the latch 25 rotates counterclockwise in the illustrated direction against the latch urging spring and engages with the half latch engaging surface 25f. The joint portion 26a is locked to prevent rotation. At this time, the slide door 10 is in a half-door state that engages with the striker 29 in the engagement recess 25a and prevents it from coming off. The state of the latch mechanism 22 at this time is called a half latch state, and the rotation position of the latch 25 is called a half latch position.

  Subsequently, it is assumed that the striker 29 further enters the engagement recess 25a as the slide door 10 is further closed. At this time, the striker 29 presses the inner wall surface of the engaging recess 25a, so that the latch 25 further rotates counterclockwise in the illustrated direction against the latch biasing spring, as shown in FIG. The engagement portion 26a is locked to the full latch engagement surface 25e to prevent rotation. At this time, the slide door 10 is in a fully closed state in which it engages with the striker 29 in the engagement recess 25a and prevents it from coming off. The state of the latch mechanism 22 at this time is called a full latch state (engaged state), and the rotation position of the latch 25 is called a full latch position.

  Further, in the half latch state or the full latch state, when the pole 26 rotates in the clockwise direction in the figure against the pole urging spring, the half latch engagement surface 25f or the full latch engagement surface 25e is locked by the engagement portion 26a. Is released. At this time, the latch 25 is pressed against the inner wall surface of the engagement recess 25a by the striker 29 that retreats from the engagement recess 25a as the sliding door 10 starts to open due to the repulsive force of the seal member, for example. Thus, it rotates in the clockwise direction shown in the figure. The slide door 10 can be released by releasing the engagement with the striker 29 in the engagement recess 25a.

  As shown in FIG. 3, the closer / release device 12 includes a latch switch 90 formed of, for example, a rotary switch. The latch switch 90 is for detecting the rotation position (unlatch position or the like) of the latch 25. Further, the closer / release device 12 has a pole drive lever 27 connected to the rotary shaft 24 so as to rotate integrally therewith. The tip of the pole drive lever 27 is curved so as to be convex upward to form a pressed portion 27a. The turning direction of the pole drive lever 27 in which the pressed portion 27a moves downward coincides with the turning direction of the pole 26 that releases the engagement state with the latch 25 described above.

  A base plate 30 made of, for example, a metal plate that extends toward the front of the vehicle is fastened to the base plate 21. The base plate 30 is fastened to the slide door 10 separately from the base plate 21. An actuator 31 that is driven and controlled by an ECU (electronic control unit) (not shown) is installed at the front lower portion of the base plate 30. The actuator 31 includes an electric motor 32 and a speed reduction mechanism 33 that decelerates the rotation of the rotation shaft of the electric motor 32. A pinion 33 a is fixed to the output shaft of the speed reduction mechanism 33.

  The first support pin 34 having a substantially cylindrical shape as a support shaft extending in the center line is fixed to the base plate 30 obliquely upward and rearward of the pinion 33a. An active lever 35 as an operating lever made of, for example, a metal plate is pivotally supported on the support pin 34. That is, the active lever 35 has a substantially circular support portion 36 through which the first support pin 34 passes and is pivotally supported. The active lever 35 has a substantially arc-shaped connecting portion 37 disposed outside the supporting portion 36 in the radial direction centered on the first supporting pin 34, and the first supporting pin 34 of the connecting portion 37 is provided on the active lever 35. A connecting portion 38 that connects one end of the first circumferential direction Ci1 (the side in the clockwise direction in the figure) and the support portion 36 in the radial direction with the first support pin 34 as the center is the circumferential direction that is the center. Have. The active lever 35 is opened to the other side (the counterclockwise rotation direction in the drawing) of the first circumferential direction Ci1 by the outer peripheral portion of the support portion 36, the inner peripheral portion of the connecting portion 37, and the side wall of the connecting portion 38. A fan-shaped groove 35a is formed.

  As shown in FIG. 4, the active lever 35 includes a first gear portion 61 and a first cam portion 62 on the outer peripheral portion of the connecting portion 37 side by side in the first circumferential direction Ci1. The first gear portion 61 includes a plurality of external teeth and meshes with the pinion 33a of the actuator 31. Therefore, the active lever 35 rotates around the first support pin 34 in a direction corresponding to the rotation direction when the pinion 33a rotates. Further, the active lever 35 has a predetermined rotation range, and the rotation of the active lever 35 is restricted when the end of the first gear portion 61 reaches the pinion 33a. The intermediate portion of the rotation regulation range including the rotation position of the active lever 35 shown in FIG. 4 that meshes with the pinion 33a at the intermediate portion in the first circumferential direction Ci1 of the first gear portion 61 is referred to as a “neutral region”.

  The first cam portion 62 is formed with a first arcuate surface 62a extending in the first circumferential direction Ci1. The diameter of the first arc surface 62a is set to an intermediate length between the diameters of the tooth tip circle and the tooth root circle of the first gear portion 61. Further, the active lever 35 is formed with a substantially U-shaped engaging groove 63 disposed at the boundary between the first gear portion 61 and the first cam portion 62. As shown in FIG. 7, the inner wall surface of the engagement groove 63 faces the first cam portion 62 of the first end tooth 64 that is a terminal external tooth adjacent to the first cam portion 62 of the first gear portion 61. When assuming that the inner side surface 63a along the side tooth profile side surface (the side surface of the so-called involute tooth profile) and the virtual outer teeth 65 are connected from the first end tooth 64 to the first cam portion 62 side, Are also defined by a bottom surface 63b that is recessed toward the inner peripheral side and an inner surface 63c that is recessed toward the first circumferential direction Ci1 that is separated from the tooth profile side surface facing the first end tooth 64 of the virtual external tooth 65. Yes. The recessed portion (illustrated by a pattern) of the engaging groove 63 forms a relief groove 66 rather than the original valley when it is assumed that the virtual external teeth 65 are connected.

  As shown in FIG. 4, an internal gear portion 37 a composed of a plurality of internal teeth is formed on the inner peripheral portion of the connecting portion 37 near the connecting portion 38. Further, the inner peripheral portion of the connecting portion 37 basically has an inner diameter equivalent to the diameter of the root circle of the inner gear portion 37a (inner teeth), and the other side of the first circumferential direction Ci1 from the inner gear portion 37a. A release portion 37b extending in the counterclockwise direction (illustrated in the drawing) is formed. Furthermore, as shown in FIG. 3, the active lever 35 extends an extending piece 39 from the support portion 36 in the radial direction obliquely rearward and downward with the first support pin 34 as the center. The distal end portion of the extending piece 39 that is separated from the first support pin 34 turns forward and is connected to the connecting portion 37 in the vicinity of the connecting portion 38.

  A substantially stepped columnar second support pin 40 having a center line extending substantially parallel to the center line of the first support pin 34 in the groove 35a of the active lever 35 is fixed to the base plate 30 and the second support A release lever 41 made of, for example, a metal plate is pivotally supported on the pin 40. That is, the release lever 41 has a substantially circular lever support portion 42 through which the second support pin 40 passes and is pivotally supported. The lever support portion 42 is also located in the groove portion 35 a of the active lever 35. A gear portion 42a composed of a plurality of external teeth is formed on the outer peripheral portion of the lever support portion 42 at an angle position diagonally forward and downward in FIG. 3, and meshes with the internal gear portion 37a of the active lever 35 in the gear portion 42a. It is possible.

Further, the release lever 41 extends a substantially arcuate lever protrusion 43 from the lever support portion 42 in the radial direction obliquely rearward and upward with the second support pin 40 as the center.
The release lever 41 is biased to the side that rotates in the clockwise direction in the figure by hooking the other end of a biasing member 95 made of, for example, a coil spring, which is hooked at one end to the base plate 30. The contact in the stopper piece 30a formed on the base plate 30 restricts the rotation in the direction. At this time, the release lever 41 is held at a predetermined initial rotation position.

  As shown in FIG. 4, when the release lever 41 is in the initial rotation position, the release lever 41 is a gear that precedes the counterclockwise rotation direction side of the internal gear portion 37a of the active lever 35 in the neutral region. The part 42a is arranged. Then, as shown by the change to FIG. 5, when the active lever 35 rotates in the illustrated counterclockwise direction, the internal gear portion 37a meshes with the gear portion 42a through a predetermined idle running section. Thus, as the active lever 35 rotates in the illustrated counterclockwise direction, the release lever 41 starts to rotate in the illustrated counterclockwise direction against the urging force of the urging member 95. The lever support portion 42 has an outer diameter that is basically equal to the diameter of the tip circle of the gear portion 42a (outer teeth), but the connecting portion 37 is formed with a release portion 37b. There is no interference.

  As shown in FIG. 3, the end of the release lever 41 (lever protruding piece 43) is hooked to the end of the release cable C1, and the release cable 41 is rotated by rotating the release lever 41 from the initial rotation position. Is pulled toward the closer / release device 12 side. That is, the electrically operated release operation force of the closer / release device 12 is generated when the release lever 41 rotates from the initial rotation position.

  A substantially cylindrical support pin 45 having a center line extending substantially parallel to the center line is fixed to the base plate 30 above the first support pin 34, and the support pin 45 is an open plate made of, for example, a metal plate. A lever 46 is pivotally supported. The open lever 46 extends a substantially arcuate first lever protrusion 47 in an upper radial direction centering on the support pin 45, and has an arm-shaped second in a lower radial direction centering on the support pin 45. The lever protrusion 48 is extended. The tip of the first lever protrusion 47 is curved so as to protrude downward above the pressed portion 27a of the pole drive lever 27 to form a pressing portion 47a.

  In the open lever 46, the end of the open cable C2 is hooked at the tip of the second lever protrusion 48. Therefore, when the open cable C2 is pulled toward the remote controller 14, the open lever 46 rotates in the counterclockwise direction shown in the figure around the support pin 45. At this time, the open lever 46 presses the pressed portion 27a of the pole drive lever 27 downward in the pressing portion 47a, so that the pole drive lever 27 rotates so that the pressed portion 27a moves downward. As a result, the pawl 26 that rotates together with the pawl drive lever 27 releases the engaged state with the latch 25. In other words, the electric release operation force of the closer / release device 12 or the manual release operation force of the operation handle 15 is caused by the open cable C2 being pulled toward the remote controller 14 and the open lever 46 turning. Is transmitted to. The pivot position of the active lever 35 shown in FIG. 5 that completes the release of the engagement state of the pawl 26 with the latch 25 is referred to as a “release position”. A range from the end of the neutral region to the release position in the prescribed rotation range of the active lever 35 is referred to as a “release region”.

  As shown in FIG. 3, a substantially cylindrical support pin 50 having a center line extending substantially parallel to the center line of the first support pin 34 is fixed to the distal end portion of the extending piece 39 of the active lever 35. A closer lever 51 made of, for example, a metal plate is pivotally supported on the support pin 50. The closer lever 51 has a lever protruding piece 52 extending in the rearward radial direction around the support pin 50. The tip of the lever protrusion 52 rises on the front side orthogonal to the paper surface to form a substantially L-shaped push-up wall 52a. The closer lever 51 is held by an appropriate holding member so as to rotate substantially integrally with the active lever 35. When the active lever 35 is in the neutral region, the interlocking piece of the latch 25 in the half-latch position is held. The push-up wall 52a is disposed below 25g. Therefore, when the closer lever 51 rotates together with the active lever 35 in the clockwise direction in the drawing, the latch 25 pressed by the interlocking piece 25g by the push-up wall 52a rotates from the half latch position to the full latch position. At this time, as described above, the sliding door 10 in the half-door state is fully closed. Needless to say, when the active lever 35 rotates from the neutral region in the clockwise direction shown in the drawing, the release lever 37 remains in the initial rotation position by moving the release portion 37b of the lever support portion 42. Absent. The rotation position of the active lever 35 shown in FIG. 6 in which the holding of the slide door 10 in the fully closed state by the latch mechanism 22 is referred to as a “close position”. The range from the end of the neutral region to the closed position in the prescribed rotation range of the active lever 35 is referred to as “closed region”.

  As shown in FIG. 3, the neutral switch 70 which consists of rotary switches, for example is installed in the baseplate 30 above the pinion 33a. The neutral switch 70 includes a switch body 71 that includes a movable piece that forms a housing and switches the electrical connection state between the circuit board and the circuit board, and has an operation shaft 72 that rotates integrally with the movable piece. Have. The operation shaft 72 is disposed at the top left end of the switch body 71 in the figure, and its axis extends substantially parallel to the axis of the pinion 33a.

  As shown in FIG. 4, the switch body 71 has a substantially claw-shaped switch side as a position limiting portion toward the active lever 35 in the second circumferential direction Ci <b> 2, which is a circumferential direction centering on the operation shaft 72. A stopper 71a is projected.

  A neutral switch lever 80 as a substantially fan-shaped neutral detection lever made of, for example, a resin material is connected to the operation shaft 72 so as to rotate integrally. The neutral switch lever 80 has a second gear portion 81 and a second cam portion 82 arranged in the outer circumferential portion thereof in the second circumferential direction Ci2. That is, the neutral switch lever 80 has a so-called missing gear shape. The second gear portion 81 includes a plurality of external teeth and can mesh with the first gear portion 61 of the active lever 35. Accordingly, the neutral switch lever 80 moves around the operation shaft 72 in a direction corresponding to the rotation direction of the active lever 35 when the first gear portion 61 and the second gear portion 81 are engaged. Rotate. A neutral switch 70 in which the operating shaft 72 rotates together with the neutral switch lever 80 as the active lever 35 rotates, detects that the active lever 35 is in the neutral region. In other words, the neutral switch 70 switches the aforementioned electrical connection state depending on whether or not the active lever 35 is in the neutral region.

  The second cam portion 82 is formed with a second arc surface 82a that can come into contact with the first arc surface 62a as the active lever 35 rotates toward the close position. As shown in FIG. 6, the second arc surface 82a extends in the first circumferential direction Ci1 when in the abutting state in contact with the first arc surface 62a. Accordingly, the neutral switch lever 80 is restricted from rotating when the first arc surface 62a protrudes radially inward with the operation shaft 72 as the center in the second arc surface 82a. On the other hand, the active lever 35 is rotatable with respect to the neutral switch lever 80 by sliding the first arc surface 62a on the second arc surface 82a.

  The distal end portion of the second cam portion 82 on the second gear portion 81 side in the second circumferential direction Ci2 forms an engagement end portion 83 that can be engaged with the engagement groove 63. As shown in FIG. 7, the outer wall surface of the engagement end portion 83 extends from the second end tooth 84, which is a terminal external tooth adjacent to the second cam portion 82 of the second gear portion 81, to the second cam portion 82 side. When it is assumed that the virtual outer teeth 85 are connected, the outer end surface 83a along the tooth profile side surface on the side facing the second end teeth 84, and the engagement end surface formed by projecting the tip portion separated from the operation shaft 72 83b. The engagement end surface 83b protrudes to the outer peripheral side from the tooth tip of the virtual external tooth 85, and has a shape (that is, a circular arc surface shape) in the engagement end portion 83 that extends the second arc surface 82a.

  Between the second arc surface 82a of the second cam portion 82 and the engagement end portion 83 in the second circumferential direction Ci2, the inner circumference is greater than the virtual arc surface 86 obtained by extending the second arc surface 82a to the engagement end portion 83. A substantially triangular notch 87 recessed to the side is formed. The notch 87 is formed in the first circumferential direction Ci1 of the first cam portion 62 when the engagement end portion 83 is engaged with the engagement groove 63 in association with, for example, turning toward the neutral region of the active lever 35 in the closed region. This is for opening the turning locus of the tip portion on the first gear portion 61 side. In other words, an extension 62b that enters the rotation locus of the virtual arcuate surface 86 is formed at the tip of the first arcuate surface 62a on the first gear portion 61 side in the first circumferential direction Ci1. In FIG. 7, a virtual surface 67 required for releasing the rotation locus of the virtual arc surface 86 is drawn. The virtual surface 67 is guided when it is assumed that the virtual arcuate surface 86 exists, so that, for example, when the active lever 35 in the closed region rotates toward the neutral region, the first gear The re-engagement of the part 61 and the second gear part 81 is invited. As shown in the pattern in FIG. 7, the first arc surface 62 a faces the first gear portion 61 because the virtual surface 67 is raised along the first arc surface 62 a toward the outer peripheral side to form the extension 62 b. It is confirmed that it is stretched.

  As described above, the engagement groove 63 is formed with a relief groove 66 that is recessed to the inner peripheral side or the like from the original valley portion of the virtual external tooth 65. The rotation trajectory of the engagement end surface 83b formed to protrude from the engagement end portion 83 engaged with the insertion groove 63 is opened.

  FIG. 8 is an explanatory diagram showing the rotation range of the neutral switch lever 80 interlocked with the active lever 35 and the electrical connection state of the corresponding neutral switch 70. As shown in the figure, the angle of the rotation range of the neutral switch lever 80 is set to about 90 °, and the rotation range corresponding to the neutral region of the active lever 35 (hereinafter, the neutral switch lever 80 is referred to for convenience). When the neutral switch lever 80 is positioned in the neutral region), the neutral switch 70 is turned off. Further, the neutral switch 70 is turned on when the neutral switch lever 80 is located in a rotation range corresponding to a rotation regulation range in which the active lever 35 exceeds the neutral region toward the release position or the close position. The ECU determines whether or not the active lever 35 is in the neutral region based on the on / off state of the neutral switch 70. The end of the rotation range of the neutral switch lever 80 corresponding to the specified rotation range in which the active lever 35 exceeds the neutral region to the closed position side is restricted by the first arc surface 62a riding on the second arc surface 82a. Needless to say, this is the rotational position of the neutral switch lever 80. When the neutral switch lever 80 is rotated, that is, when the first arcuate surface 62a and the second arcuate surface 82a are in contact with each other, the end surface 80a of the neutral switch lever 80 on the side preceding the counterclockwise rotation shown in the drawing. Approaches or contacts the switch side stopper 71a of the neutral switch 70. Thereby, the rotation of the neutral switch lever 80 in the counterclockwise direction shown in the figure is restricted.

Next, the operation of this embodiment will be described.
First, it is assumed that the latch mechanism 22 is in a half-latch state and the active lever 35 is in a neutral region as shown in FIG. In this state, the ECU detects that the active lever 35 is in the neutral region by the neutral switch 70 in which the operation shaft 72 rotates integrally with the neutral switch lever 80. Based on this, the actuator 31 is driven by the ECU to rotate the active lever 35 in the clockwise direction shown in the figure. Then, when the active lever 35 rotates within the specified rotation range, if the first gear portion 61 and the second gear portion 81 are in an engaged state, a rotation direction corresponding to the rotation direction (here, the counterclockwise shown in the figure). The neutral switch lever 80 rotates in the rotation direction. When the first arc surface 62a and the second arc surface 82a are brought into contact with the rotation of the active lever 35 toward the closed position, the neutral switch lever 80 is centered on the operation shaft 72 on the second arc surface 82a. The first arc surface 62a protrudes inward in the radial direction, and the rotation is restricted. On the other hand, the active lever 35 can be rotated with respect to the neutral switch lever 80 by sliding the first arc surface 62a on the second arc surface 82a and the engagement end surface 83b. Accordingly, the active lever 35 rotates toward the closed position while sliding the first arc surface 62a on the second arc surface 82a and the engagement end surface 83b while leaving the neutral switch lever 80 left. In this way, the neutral switch lever 80 does not need to continue to rotate until the active lever 35 reaches the closed position, thereby reducing the movement region. The driving of the actuator 31 is stopped by the ECU when the latch switch 90 detects that the latch 25 is at the full latch position, for example.

  Thereafter, when the active lever 35 in the closed region rotates toward the neutral region, the active lever 35 initially has the first arc on the second arc surface 82a and the engagement end surface 83b with the neutral switch lever 80 remaining. It rotates while sliding the surface 62a. At this time, as shown in FIG. 9, the first arc surface 62a (extension portion 62b) slides on the engagement end surface 83b until the engagement groove 63 reaches the engagement end 83, so that the neutral The rotation of the switch lever 80 is restricted. Further, as shown by a two-dot chain line in FIG. 9, the neutral switch lever 80 is rotated in the clockwise direction (one-way rotation) so that the neutral switch lever 80 advances in the meshing direction with the active lever 35 by an amount corresponding to the initial gap. Even if it does, the 1st circular arc surface 62a (extension part 62b) is facing the engagement end surface 83b until just before the engagement groove | channel 63 arrives at the engagement end part 83, The rotation of the neutral switch lever 80 concerned (Tilt) is reduced and the posture is further stabilized.

  Alternatively, as shown in FIG. 10, even if the neutral switch lever 80 is rotated counterclockwise (reverse rotation) so that it is delayed in the meshing direction with the active lever 35 by the initial gap. Since the switch-side stopper 71a of the neutral switch 70 faces the end face 80a of the neutral switch lever 80, the rotation (tilt) of the neutral switch lever 80 is also reduced, and the posture thereof is further stabilized.

  When the active lever 35 further rotates toward the neutral region, the first end teeth 64 (inner surface 63a) of the first gear portion 61 reach the engagement end portion 83 as shown by the change to FIG. By pressing this, the neutral switch lever 80 starts to rotate while the engaging end 83 is engaged in the engaging groove 63, and the first gear portion 61 is engaged with the second gear portion 81. Then, the neutral switch lever 80 is rotated. That is, the active lever 35 and the neutral switch lever 80 are engaged with the first gear portion 61 and the second arcuate surface 82a from the contact state of the first arcuate surface 62a and the second arcuate surface 82a after the engagement end 83 is engaged with the engagement groove 63. The second gear portion 81 is switched to the meshing state. At this time, as described above, since the posture of the neutral switch lever 80 is further stabilized, the engagement end 83 can be more smoothly engaged with the engagement groove 63 that has reached the engagement end 83. It is possible to further stabilize the transition of the first gear portion 61 and the second gear portion 81 to the meshing state. At this time, the turning locus of the extension 62b is opened by the notch 87, and the turning locus of the engagement end face 83b is opened by the escape groove 66 as described above.

The driving of the actuator 31 is stopped by the ECU when the neutral switch 70 detects that the active lever 35 is in the neutral region.
Next, the effect of this embodiment will be described.

  (1) In this embodiment, when the active lever 35 is rotated within the specified rotation range, if the first gear portion 61 and the second gear portion 81 are in the meshing state, the rotation direction according to the rotation direction. Thus, the neutral switch lever 80 rotates around the operation shaft 72. The neutral switch 70 detects that the active lever 35 is in the neutral region. When the first arc surface 62a and the second arc surface 82a are brought into contact with the rotation of the active lever 35 toward the closed position, the neutral switch lever 80 is centered on the operation shaft 72 on the second arc surface 82a. The first arc surface 62a protrudes inward in the radial direction, and the rotation is restricted. On the other hand, the active lever 35 is rotatable with respect to the neutral switch lever 80 by sliding the first arc surface 62a on the second arc surface 82a. Accordingly, the active lever 35 can rotate toward the closed position while sliding the first arc surface 62a on the second arc surface 82a while leaving the neutral switch lever 80 remaining. Further, the active lever 35 in the closed region can be rotated toward the neutral region while sliding the first arc surface 62a on the second arc surface 82a while leaving the neutral switch lever 80 remaining. At this time, the rotation of the neutral switch lever 80 in one direction is restricted to a range until the engagement end 83 comes into contact with the first cam portion 62 unless the extension 62 b passes through the engagement end 83. . As described above, since the posture of the neutral switch lever 80 is further stabilized, the engagement end 83 can be more smoothly engaged with the engagement groove 63 that has reached the engagement end 83, and the first gear can be engaged. The transition to the meshing state of the part 61 and the second gear part 81 can be further stabilized. Further, the rotation locus of the extension portion 62b at this time is opened by the notch 87, so that interference between the first cam portion 62 and the second cam portion 82 can be suppressed.

  (2) In the present embodiment, when the active lever 35 in the closed region rotates toward the neutral region while sliding the first arc surface 62a on the second arc surface 82a while leaving the neutral switch lever 80, The one-way rotation of the neutral switch lever 80 is further restricted by approaching the first cam portion 62 (first arc surface 62a) by the amount of protrusion of the engagement end surface 83b. Thus, the posture of the neutral switch lever 80 is further stabilized, so that the engagement end 83 can be more smoothly engaged in the engagement groove 63 that has reached the engagement end 83, and the first gear The transition to the meshing state of the part 61 and the second gear part 81 can be further stabilized. Further, the rotation trajectory of the engagement end surface 83b at this time is opened by the escape groove 66, so that interference between the engagement end portion 83 and the engagement groove 63 can be suppressed.

  (3) In this embodiment, when the first arc surface 62a and the second arc surface 82a are in contact with each other, the switch-side stopper 71a suppresses the separation of the engagement end portion 83 from the first cam portion 62. Thus, the rotational position of the neutral switch lever 80 is limited. Therefore, when the active lever 35 in the closed region rotates toward the neutral region while sliding the first arc surface 62a on the second arc surface 82a with the neutral switch lever 80 remaining, the reverse of the neutral switch lever 80 is obtained. The rotation of the direction is suppressed by the switch side stopper 71a. Thus, the posture of the neutral switch lever 80 is further stabilized, so that the engagement end 83 can be more smoothly engaged in the engagement groove 63 that has reached the engagement end 83, and the first gear The transition to the meshing state of the part 61 and the second gear part 81 can be further stabilized.

  (4) In the present embodiment, when the active lever 35 rotates toward the closed position, the neutral switch lever 80 contacts the first arc surface 62a at two locations, the second arc surface 82a and the engagement end surface 83b. By being in the state, the rotation regulation can be more reliably performed.

  (5) In the present embodiment, interference between components can be suppressed by restricting the rotation (rattle) of the neutral switch lever 80. In addition, since the inclination (falling amount) of the neutral switch lever 80 is regulated within a certain variation range, it is possible to improve the accuracy of the on / off state switching timing of the neutral switch 70. For this reason, the control accuracy of the closer / release device 12 itself can be improved, and the convenience can be improved.

  (6) In the present embodiment, the neutral switch lever 80 does not need to continue to rotate until the active lever 35 reaches the closed position, so that the movement region is reduced, and the degree of freedom of arrangement of the components is increased. It can be improved further.

  (7) In the present embodiment, the movement region of the neutral switch lever 80, that is, the movement region of the operation shaft 72 is reduced, so that, for example, the operation shaft 72 rotates excessively and is neutral except in the neutral region of the active lever 35. It can suppress that the on / off state of the switch 70 switches. That is, it is possible to avoid the operation shaft 72 that rotates together with the neutral switch lever 80 from exceeding the detectable range of the neutral switch 70.

In addition, you may change the said embodiment as follows.
In the above-described embodiment, the switch body stopper 71 (neutral switch 70) is provided with the switch-side stopper 71a so as to face the end face 80a of the neutral switch lever 80, thereby reducing the rotation (tilt) of the neutral switch lever 80. did. Instead of this, or in addition to this, a substantially claw-shaped switch lever side stopper as a position limiting portion is provided on the end face 80a of the neutral switch lever 80 so as to face the switch body 71 (neutral switch 70). The rotation (tilt) of the neutral switch lever 80 may be reduced.

  In the above-described embodiment, by an urging member (for example, a tension spring or a torsion spring) as an appropriate position limiting portion that urges the neutral switch lever 80 in the rotation direction in which the engagement end surface 83b contacts the first arc surface 62a. The rotation (tilt) of the neutral switch lever 80 may be reduced.

In the embodiment, the switch side stopper 71a of the switch body 71 (neutral switch 70) may be omitted.
In the above-described embodiment, the distal end surface of the engagement end portion 83 that is separated from the operation shaft 72 may have a shape along the tooth tip of the second gear portion 81, for example. That is, the engagement end surface 83 b does not have to be formed to protrude from the distal end portion of the engagement end portion 83. In this case, the escape groove 66 may not be formed in the engagement groove 63.

  In the above embodiment, the actuator 31 that holds the slide door 10 in the fully closed state by the latch mechanism 22 is driven by a motor lock (for example, when the pinion 33a reaches the end of the first gear portion 61 and becomes unrotatable) The ECU may be stopped by detecting a sudden increase in motor current or the like.

  In the above embodiment, the actuator 31 that releases the latch mechanism 22 in the engaged state is driven by, for example, a motor lock (motor current caused by the pinion 33a reaching the end of the first gear portion 61 and becoming unrotatable. The ECU may be stopped by detecting a sudden increase or the like.

In the embodiment, the neutral switch 70 may be a rotary encoder or a hall sensor, for example.
-In the said embodiment, you may abbreviate | omit the release function by the closer release apparatus 12 grade | etc.,. Even in this case, the rotation of the neutral switch lever 80 may be regulated while the active lever 35 is rotating from the neutral region toward the closed position.
