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. The vehicle door lock device includes an upper latch mechanism and a lower latch mechanism provided at the upper end and the lower end of a vehicle door, respectively. Each of the upper latch mechanism and the lower latch mechanism holds the door in the half door state and the fully closed state in the half latch state and the full latch state, respectively. In addition, the vehicle door lock device includes an actuator that operates the upper latch mechanism so that the upper latch mechanism in the half latch state is in the full latch state.

In the vehicle door lock device, when the upper portion of the door is in the half door state, the upper latch mechanism is changed from the half latch state to the full latch state by the actuator.
As described above, the door is held in the fully closed state by the upper latch mechanism and the lower latch mechanism.

  In other words, this vehicle door lock device has a function (a so-called closer function) in which only the upper latch mechanism at the upper end of the door is changed from the half latch state to the full latch state. This is because the upper part of the door has a relatively low rigidity, and the upper latch mechanism may stop in a half-latch state.

JP 2017-43990 A

  By the way, in Patent Document 1, there is a possibility that the lower latch mechanism stops in a half-latch state, for example, when the door is slowly closed. In this case, there is a possibility that the door cannot be fully closed accurately.

  Therefore, it is conceivable to add a function for changing the lower latch mechanism from the half latch state to the full latch state. However, in this case, the function (actuator or the like) is required for both the upper latch mechanism and the lower latch mechanism, and the weight of the entire apparatus is inevitably increased.

  An object of the present invention is to provide a vehicle door lock device that can more accurately fully close a vehicle door while suppressing an increase in weight.

  An automotive door lock device that solves the above problems is provided at an upper end of a vehicle door, and includes an upper closer having an upper latch mechanism that holds the door in a half-door state and a fully-closed state in a half-latch state and a full-latch state, A lower closer provided at a lower end of the door and having a lower latch mechanism for holding the door in a half-latch state and a full-latch state in a half-latch state and a full-latch state; And an actuator that operates the upper latch mechanism and the lower latch mechanism so as to be in a state.

  According to this configuration, when the door is in the half door state, the upper latch mechanism and the lower latch mechanism can be changed from the half latch state to the full latch state by the actuator, and as a result, the door can be more fully closed. Further, since the actuator may be one shared by the upper latch mechanism and the lower latch mechanism, for example, an increase in the weight of the entire apparatus can be suppressed as compared with a case where the actuators are individually provided in the upper latch mechanism and the lower latch mechanism, for example.

  In the vehicle door lock device, the actuator includes an electric motor, and the upper latch mechanism and the lower latch mechanism are both changed from a half latch state to a full latch state by rotation of the electric motor in one direction. It is preferable to operate the lower latch mechanism.

  According to this configuration, it is possible to operate the upper latch mechanism and the lower latch mechanism so that both the upper latch mechanism and the lower latch mechanism are changed from the half latch state to the full latch state by the rotation of the electric motor in the one direction. Therefore, for example, the time required for the operation can be further reduced as compared with the case where the upper latch mechanism and the lower latch mechanism are selectively operated according to the rotation direction of the electric motor.

  The vehicle door lock device includes a connecting member that is connected to the upper latch mechanism and operates the upper latch mechanism, and the actuator includes a close lever to which rotation of the electric motor is transmitted, and is provided in the lower closer. The close lever is connected to the lower latch operating portion that operates the lower latch mechanism in accordance with the rotation of the electric motor in the one direction and the connecting member, and in accordance with the rotation of the electric motor in the one direction. It is preferable to have an upper latch actuating portion that retracts the connecting member to actuate the upper latch mechanism.

  According to this configuration, the close lever includes the lower latch operating portion and the upper latch operating portion, so that it can have two functions (operation of the upper latch mechanism and operation of the lower latch mechanism) with one component.

Further, the inside in the width direction of the vehicle heading toward the inside of the vehicle interior is referred to as “vehicle inside”, and the outside in the width direction of the vehicle toward the outside of the vehicle interior is referred to as “vehicle outside”. In particular, the direction of the door of a vehicle is basically regarded as a closed state.

  As shown in FIG. 1, a so-called pillarless-type opening 2 that does not have a center pillar is formed in a side portion of a body 1 of a vehicle, and a swing door 11 and a slide are fitted to the opening 2. The door 12 is juxtaposed in the front-rear direction. In other words, the swing door 11 is rotatably connected to the body 1 by a door hinge (not shown) provided at the front edge portion thereof, and turns into the entrance / exit on the front seat side by rotating about the door hinge. Open and close the front of the opening 2. On the other hand, the sliding door 12 is connected to the body 1 so as to be movable in the front-rear direction by an appropriate support member (not shown). Open and close.

  The swing door 11 includes a door body 13 that forms the lower part thereof. The door body 13 is a bag-like structure formed by combining a door outer panel and a door inner panel (not shown). The swing door 11 includes a door frame 14 attached to the upper end portion of the door body 13. The door frame 14 has a substantially cylindrical upright portion 14a that is fixed to the rear portion of the door body 13 and extends upward, and is fixed to the front portion of the door body 13 and extends obliquely rearward and upward at the upper end of the upright portion 14a. And has a substantially arcuate upper edge 14b connected to the. In addition, the upright column part 14a is connected to the inside of the door main body 13 in the height direction of the vehicle.

  An operation handle 15 is swingably connected to the door body 13. The door main body 13 is provided with a remote controller (remote controller) 16 linked to the operation handle 15 in the internal space.

  A lower closer 20 is installed in the interior space of the rear lower end of the door body 13 (the rear lower end of the swing door 11). The lower closer 20 has a lower latch mechanism 30 that holds the swing door 11 in a fully closed state or a half door state (closed state) by engaging with a striker STL provided in the body 1 at the lower end of the opening 2. The lower latch mechanism 30 is connected to the remote control 16 via the open cable C1, and the operating force of the operation handle 15 is transmitted via the remote control 16 and the open cable C1, thereby holding the swing door 11 in the closed state. Is released.

  The lower closer 20 is provided with an actuator 40. The lower closer 20 is linked to the actuator 40 in the lower latch mechanism 30. The lower latch mechanism 30 operates so that the swing door 11 in the half-door state is closed until the actuator 40 is driven and controlled by an ECU (electronic control unit) 90. The actuator 40 is connected to the remote controller 16 via the cancel cable C2, and the closing operation of the swing door 11 is stopped by transmitting the operation force of the operation handle 15 via the remote controller 16 and the cancel cable C2. Stop the output as much as possible.

  On the other hand, an upper closer 50 is installed at the upper end of the upright column portion 14a (the upper end of the rear portion of the swing door 11) in the internal space. The upper closer 50 has an upper latch mechanism 60 that holds the swing door 11 in a fully closed state or a half door state (closed state) by engaging with a striker STU provided in the body 1 at the upper end of the opening 2. The upper latch mechanism 60 is connected to the remote control 16 via the open cable C3, and the operating force of the operation handle 15 is transmitted via the remote control 16 and the open cable C3, whereby the swing door 11 is held in the closed state. Is released.

  The upper latch mechanism 60 is connected to one end of a drive cable C4 as a connecting member. The drive cable C4 extends downward in the upright column portion 14a and is connected to the actuator 40 of the lower closer 20 at the other end. The upper latch mechanism 60 is controlled so that the actuator 40 is driven and controlled by the ECU 90 so that the power of the actuator 40 is transmitted via the drive cable C4 and the swing door 11 in the half door state is closed to the fully closed state. Operates on. That is, the actuator 40 of the lower closer 20 is also used as an actuator for driving the upper closer 50.

Next, the lower closer 20 will be described.
As shown in FIGS. 2 and 3, the lower closer 20 has a base plate 31 made of, for example, a metal plate. The base plate 31 has a bottom wall 31a that extends along the lower end surface of the swing door 11 and is fastened thereto, and a vertical wall 31b that stands up from the vehicle inner end of the bottom wall 31a and has a substantially L shape. Yes. The base plate 31 is formed with a substantially slit-like striker entrance / exit 31c between the bottom wall 31a and the vertical wall 31b. The striker entry / exit portion 31c is arranged so that the striker STL enters when the swing door 11 is closed.

  The lower latch mechanism 30 is integrated with the rotation shaft 34 and a pair of parallel rotation shafts 33, 34 that are pivotally supported on the bottom wall 31 a of the base plate 31, a latch 35 that is rotatably connected to the rotation shaft 33, and the rotation shaft 34. And a pole 36 that is pivotably connected.

  The latch 35 is formed with a substantially U-shaped engaging recess 35a in accordance with the arrangement of the striker entry / exit portion 31c. And the latch 35 forms the 1st nail | claw part 35b and the 2nd nail | claw part 35c in the one side and the other side (FIG. 3 side of a clockwise rotation direction and a counterclockwise rotation direction) on both sides of the engagement recessed part 35a. . In the circumferential direction, the end surface of the front end portion of the first claw portion 35b that is separated from the second claw portion 35c and the end surface that faces the first claw portion 35b of the front end portion of the second claw portion 35c are the full latch engaging surface 35d and the half A latch engaging surface 35e is formed. The latch 35 is biased toward the side rotating in the clockwise direction in the figure by latching the other end of a latch biasing spring (not shown) whose one end is latched to the base plate 31, and the resin body ( By abutting a latch stopper (not shown) installed at a not-shown position, the rotation in that direction is restricted and held at a predetermined initial turning position (hereinafter referred to as “unlatched position”). The latch 35 projects a substantially arm-like interlocking piece 35f on the opposite side of the second claw portion 35c with the rotation shaft 33 interposed therebetween.

  On the other hand, the pole 36 forms a substantially claw-like engagement piece 36a extending from the rotating shaft 34 to one side in the radial direction (lower left side in FIG. 3). The pole 36 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 engagement piece 36a to the lower side in the figure, and reaches a predetermined initial turning position. Retained. A pole drive lever 37 is connected to the tip of the rotary shaft 34 on the side away from the pole 36 so as to rotate integrally.

Here, the basic operation of the lower latch mechanism 30 will be described.
In a state in which the swing door 11 is opened, the latch 35 held at the unlatched position makes the engaging recess 35 a face the striker STL fixed to the body 1. That is, the engagement recess 35a opens the entry path of the striker STL accompanying the closing operation of the swing door 11 together with the striker entry / exit part 31c. Further, the pole 36 held at a predetermined initial rotation position has the engaging piece 36a disposed in front of the second claw portion 35c. The state of the lower latch mechanism 30 at this time is referred to as an unlatched state (release state).

  Next, it is assumed that the striker STL has entered the engagement recess 35a with the closing operation of the swing door 11. At this time, the striker STL presses the inner wall surface of the engagement recess 35a, so that the latch 35 rotates counterclockwise in the direction against the latch biasing spring and engages with the half latch engagement surface 35e. The joint piece 36a is locked to prevent rotation (see FIG. 4A). At this time, the swing door 11 is in a half-door state that engages with the striker STL in the engagement recess 35a and prevents it from coming off. The state of the lower latch mechanism 30 at this time is called a half latch state, and the rotation position of the latch 35 is called a half latch position.

  Subsequently, it is assumed that the striker STL further enters the engagement recess 35a as the swing door 11 is further closed. At this time, the inner wall surface of the engaging recess 35a is pressed by the striker STL, so that the latch 35 further rotates counterclockwise in the illustrated direction against the latch urging spring, as shown in FIG. The engagement piece 36a is locked to the full latch engagement surface 35d to prevent rotation. At this time, the swing door 11 is in a fully closed state in which it engages with the striker STL in the engagement recess 35a and prevents it from coming off. The state of the lower latch mechanism 30 at this time is called a full latch state (engaged state), and the rotation position of the latch 35 is called a full latch position.

  Further, in the half latch state or the full latch state, when the pole 36 rotates counterclockwise in the illustrated clockwise direction, the half latch engagement surface 35e or the full latch engagement surface 35d is locked by the engagement piece 36a. Is released. At this time, the latch 35 is pressed against the inner wall surface of the engagement recess 35a by the striker STL that retreats from the engagement recess 35a as the swing door 11 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. Then, the swing door 11 can be released by releasing the engagement with the striker STL in the engagement recess 35a.

  The lower latch mechanism 30 is linked to the above-described open cable C1 via an open lever (not shown) in the pole drive lever 37. When the operation handle 15 is operated, the operation force is transmitted to the pole drive lever 37 via the remote controller 16, the open cable C1, and the open lever, so that the pole 36 together with the pole drive lever 37 is rotated as described above. It is configured to move.

  As shown in FIGS. 2 and 3, the lower closer 20 has a main bracket 21 made of, for example, a metal plate, which is fastened to the base plate 31 at the upper end portion of the vertical wall 31 b and spreads upward. The main bracket 21 is fastened to the swing door 11 separately from the base plate 31. As shown in FIG. 5, the main bracket 21 has a substantially fan-shaped first mounting portion 22 and a substantially triangular second mounting portion 23 that protrudes obliquely forward and upward from the first mounting portion 22. Furthermore, it has a substantially tongue-shaped cable attachment portion 24 extending rearward from the upper end of the first attachment portion 22.

  The above-described actuator 40 is installed on the main bracket 21. The actuator 40 includes an electric motor 41 and a speed reduction mechanism 42 that decelerates the rotation of the rotating shaft of the electric motor 41. The speed reduction mechanism 42 is fastened to the second mounting portion 23 of the main bracket 21. Yes. The speed reduction mechanism 42 includes a worm gear and an appropriate planetary gear device having, for example, a ring gear, a sun gear, and a carrier as a fixed shaft, an input shaft, and an output shaft, respectively.

  As shown in FIG. 6, the actuator 40 has an output gear 43 that rotates integrally with the carrier inside the speed reduction mechanism 42. Furthermore, the actuator 40 has a cancel lever 44 made of, for example, a resin, which is connected to the output gear 43 so as to be rotatable about an axis parallel to the axis of the output gear 43 at an obliquely lower front position. The actuator 40 is connected to the above-described cancel cable C2 at the cancel lever 44. The cancel lever 44 is connected to an appropriate cancel member that can be engaged with and disengaged from the ring gear of the speed reduction mechanism 42. When the operating force of the operating handle 15 is transmitted as described above, the cancel lever 44 rotates around the axis and releases the engaged state of the cancel member and the ring gear. At this time, the ring gear is rotatable, and the rotation of the output gear 43 together with the carrier is stopped, that is, the output of the actuator 40 is stopped. That is, the actuator 40 can block the output transmission path of the electric motor 41 therein.

  As shown in FIGS. 2 and 3, the actuator 40 includes a close lever made of, for example, a metal plate, which is connected to the first mounting portion 22 of the main bracket 21 so as to be rotatable around an axis parallel to the axis of the speed reduction mechanism 42. 45. The close lever 45 has a substantially sickle-shaped first lever protrusion 46 that extends in the radial direction centered on the axis thereof (that is, the direction approaching the speed reduction mechanism 42) and extends in the radial direction toward the rear. A substantially lever-shaped second lever protrusion 47 is provided.

  A sector gear portion 46 a that meshes with the output gear 43 is formed on the outer peripheral portion of the first lever protrusion 46. Therefore, when the output gear 43 rotates, the close lever 45 rotates in conjunction with this.

  At the tip of the second lever protrusion 47, a pressing piece 47a is formed as a lower latch actuating portion that rises at a substantially right angle from the end surface on the side preceding the clockwise direction in the figure. The pressing piece 47a is configured such that an interlocking piece 35f of the latch 35 located at the half latch position is arranged on the turning locus in the clockwise direction shown in the figure (see FIG. 4A). Therefore, when the close lever 45 rotates in the clockwise direction in the figure, the latch 35 pressed by the interlocking piece 35f by the pressing piece 47a rotates in the counterclockwise direction in the figure and reaches the full latch position (FIG. 4B). reference).

  In addition, a substantially keyhole-shaped cable lead-in hole 47b is formed at the tip of the second lever protrusion 47 on the side preceding the counterclockwise rotation direction in the drawing. A substantially triangular cable lead-in plate 48 made of, for example, a metal plate is fastened to the tip of the second lever protrusion 47. The cable lead-in plate 48 is bent with respect to a base end portion fastened to the second lever projecting piece 47 so that a distal end portion is displaced to the vehicle outer side. A gap in the width direction of the vehicle is formed between the two. A substantially circular cable lead-in hole 48a concentric with the cable lead-in hole 47b is formed at the tip. The cable drawing plate 48 forms a cable drawing portion 49 as an upper latch operating portion in cooperation with the second lever protruding piece 47.

The actuator 40 is connected to the drive cable C4 described above at the cable lead-in portion 49 of the close lever 45.
That is, a sub bracket 25 made of, for example, a metal plate is attached to the cable mounting portion 24 of the main bracket 21 so as to be overlapped from the outside of the vehicle. The sub bracket 25 is formed in a substantially tongue shape in accordance with the outer shape of the cable attachment portion 24. On the other hand, the movement of the outer casing 70 of the drive cable C4 along the longitudinal direction is restricted in a state where the distal end portion 71 on the lower closer 20 side is sandwiched between the cable attachment portion 24 and the sub bracket 25. A terminal 76 on the lower closer 20 side exposed from the outer casing 70 of the wire 75 slidably inserted into the outer casing 70 is formed in a substantially cylindrical shape concentric with the cable drawing hole 47b and the like. Both ends of the terminal 76 of the wire 75 are connected to the cable drawing portion 49 (close lever 45) by being rotatably inserted into the cable drawing hole 47b and the cable drawing hole 48a. When the close lever 45 rotates in the clockwise direction in the figure, the wire 75 is drawn from the outer casing 70 to the lower closer 20 side.

Next, the upper closer 50 will be described.
As shown in FIGS. 7-9, the upper closer 50 is provided with the housing 61 mounted in the upper end part of the standing pillar part 14a. The housing 61 includes a main plate 62 made of, for example, a metal plate, a sub plate 63 made of, for example, a metal plate disposed substantially in front of the main plate 62, and the main plate 62 and the sub plate 63 between the main plate 62 and the sub plate 63. And a sandwiched resin body 64. The housing 61 is formed with a substantially slit-like striker entry / exit portion 61 a between the sub-plate 63 and the resin body 64. The striker entrance / exit 61a is arranged so that the striker STU enters when the swing door 11 is closed.

  The main plate 62 is formed with a substantially L-shaped cable attachment portion 62a that rises forward from its lower end. The outer casing 70 of the drive cable C4 described above is restricted from moving along the longitudinal direction in a state in which the distal end portion 72 on the upper closer 50 side is held by the cable attachment portion 62a.

  The upper latch mechanism 60 includes a latch 65 and a pole 66 accommodated in the resin body 64. The latch 65 and the pole 66 are pivotally supported by a pair of parallel support shafts 67 and 68 that extend between the main plate 62 and the sub plate 63 so as to penetrate the resin body 64. Both support shafts 67 and 68 are juxtaposed in the height direction of the vehicle.

  The latch 65 is formed with a substantially U-shaped engaging recess 65a in accordance with the arrangement of the striker in / out portion 61a. The latch 65 has a pair of protrusions 65b and 65c arranged in the circumferential direction on the opposite side of the engagement recess 65a sandwiching the support shaft 67. The end surface of one protrusion 65b disposed on the side preceding the counterclockwise direction shown in the drawing forms the full latch engaging surface 65d, and the end surface of the other protrusion 65c preceding the direction corresponds to a half latch. An engagement surface 65e is formed. The latch 65 is urged toward the side rotating in the counterclockwise direction in the figure when the other end of a latch urging spring (not shown) with one end hooked on the housing 61 is hooked. By abutting on a latch stopper (not shown) installed at 61, the rotation in this direction is restricted and held at a predetermined initial rotation position (unlatch position). Note that the latch 65 projects a claw-like interlocking piece 65f in one radial direction (rightward in FIG. 7) with the support shaft 67 as the center.

  On the other hand, the pole 66 forms a substantially claw-like engagement piece 66a extending from the support shaft 68 to one side in the radial direction (left side in FIG. 7). Further, the pole 66 forms a substantially arm-shaped pressed portion 66b that extends from the support shaft 68 to the other side in the radial direction (the lower left side in FIG. 7). The pole 66 is biased by a pole biasing spring (not shown) to the side that rotates in the clockwise direction in the figure, that is, the side that moves the engagement piece 66a upward, and is held at a predetermined initial rotation position. .

The basic operation of the upper latch mechanism 60 (latch 65, pole 66) is the same as that of the lower latch mechanism 30 except that the sign and direction are different, and the description thereof is omitted.
The main plate 62 is provided with a support shaft 51 extending below the pole 66 and the like in parallel with the center line of the support shaft 67. The support shaft 51 is provided with a release lever 52 made of, for example, a metal plate. It is supported. The release lever 52 has a substantially arm-shaped connecting portion 52a extending in the radial direction around the support shaft 51, and a pressing portion where the pressed portion 66b of the pole 66 is positioned on a turning locus in the clockwise direction of the drawing. 52b.

  The upper latch mechanism 60 is connected to the above-described open cable C3 at the connection portion 52a. When the operating handle 15 is operated, the operating force is transmitted via the remote controller 16 and the open cable C3, so that the release lever 52 rotates in the clockwise direction shown in the figure. Then, the pole 66 pressed by the pressed portion 66b is rotated in the illustrated counterclockwise direction by the pressing portion 52b. At this time, if the upper latch mechanism 60 is in the half latch state or the full latch state, the engagement of the half latch engagement surface 65e or the full latch engagement surface 65d by the engagement piece 66a is released. Then, the swing door 11 can be released by releasing the engagement with the striker STU in the engagement recess 65a.

  The resin body 64 is formed with a guide portion 64a that communicates in the vehicle height direction along its rear edge, and the slider 55 is slidably disposed in the guide portion 64a in the communication direction. Has been. The slider 55 is made of, for example, a metal plate, has a substantially long main body portion 55a located in the guide portion 64a, and is connected to the lower end of the main body portion 55a so as to be exposed from the guide portion 64a. Connection portion 55b. The upper latch mechanism 60 is connected to the drive cable C4 (wire 75) described above at the connection portion 55b. Therefore, as described above, when the wire 75 is pulled to the lower closer 20 side, the slider 55 moves downward along the guide portion 64a. The slider 55 is hooked with the other end of a tension coil spring 56 whose one end is locked to the sub-plate 63. The slider 55 is urged by the tension coil spring 56 to the side that moves upward (that is, the direction opposite to the direction in which the wire 75 is retracted), and the slider 55 abuts the terminal end of the guide portion 64a, thereby restricting movement in that direction. And held at a predetermined initial position.

  The slider 55 is formed with a substantially rectangular long hole 55c that communicates in the front-rear direction within the range of the main body 55a. When the slider 55 is in the initial position, the long hole 55c opens the movement locus of the interlocking piece 65f when the latch 65 moves between the unlatched position and the full latched position. When the latch 65 is in the half latch position, the interlocking piece 65f is inserted through the elongated hole 55c (see FIG. 9). Therefore, when the slider 55 moves downward from the initial position along the guide portion 64a in a state where the latch 65 is in the half latch position, the latch 65 pressed by the interlocking piece 65f on the inner wall surface at the upper end of the long hole 55c is illustrated. It turns clockwise and reaches the full latch position. At this time, the swing door 11 is closed until the half door state is changed to the fully closed state.

  When the drawing of the wire 75 to the lower closer 20 side is completed, the slider 55 is urged by the tension coil spring 56 while leaving the latch 65 in the full latch position, and returns to the initial position. At this time, it goes without saying that the long hole 55c opens the movement locus of the interlocking piece 65f when the latch 65 moves from the full latch position to the unlatching position.

  Next, the operation when the swing door 11 reaches the half-door state with the closing operation will be described. At this time, both the lower latch mechanism 30 and the upper latch mechanism 60 are in a half latch state (see FIGS. 4A and 9). Note that the vehicle door lock device includes an appropriate detection member (not shown) that detects that at least one of the lower latch mechanism 30 and the upper latch mechanism 60 is in a half latch state or a full latch state. Based on the detection result of the detection member, it is detected that the swing door 11 is in a half door state or a fully closed state. Then, when it is detected that the swing door 11 is in the half-door state, the ECU 90 starts driving the actuator 40 so as to perform the closing operation to the fully closed state.

  When the electric motor 41 rotates in one direction as the actuator 40 is driven, the rotation is transmitted to the close lever 45 via the speed reduction mechanism 42 and the output gear 43, and the close lever 45 moves in one direction (FIG. 4A). In the clockwise direction). At this time, the latch 35 whose pressing piece 47a presses the interlocking piece 35f rotates in the counterclockwise direction shown in the figure and reaches the full latch position (see FIG. 4B). Then, the latch 35 that has reached the full latch position is prevented from rotating by engaging the engagement piece 36a of the pole 36 with the full latch engagement surface 35d, and the lower latch mechanism 30 enters the full latch state.

  At the same time, when the closing lever 45 is rotated in one direction, the wire 75 is drawn to the lower closer 20 side by the cable drawing portion 49, and the slider 55 is moved downward along the guide portion 64a against the urging force of the tension coil spring 56. Moving. At this time, the latch 65 pressed by the interlocking piece 65f on the inner wall surface of the long hole 55c is rotated in the clockwise direction in the drawing to reach the full latch position. Then, the latch 65 that has reached the full latch position is prevented from rotating by the engagement piece 66a of the pole 66 being locked to the full latch engagement surface 65d, and the upper latch mechanism 60 enters the full latch state.

Thus, the swing door 11 is fully closed.
When it is detected that the swing door 11 is in the fully closed state based on the detection result of the detection member, the ECU 90 stops driving the actuator 40 and rotates the electric motor 41 in the reverse direction. Start driving.

  When the electric motor 41 rotates in the reverse direction as the actuator 40 is driven, the rotation is transmitted to the close lever 45 via the speed reduction mechanism 42 and the output gear 43, and the close lever 45 is moved in the reverse direction (FIG. 4B). In the counterclockwise direction). At this time, the latch 35 where the interlocking piece 35f is released from the pressing piece 47a is released from the turning locus to the unlatched position (see FIG. 3).

  In addition, when the closing lever 45 rotates in the reverse direction, the slider 55 is biased by the tension coil spring 56 while leaving the latch 65 in the full latch position, and returns to the initial position while pulling the wire 75 to the upper closer 50 side. . At this time, the latch 65 in which the interlocking piece 65f is released from the inner wall surface of the long hole 55c is released from the turning locus to the unlatched position (see FIG. 7).

  When the operation handle 15 is operated when the swing door 11 is in the half door state or the fully closed state, the operation force is transmitted to the poles 36 and 66 in the above-described manner, and the half by the engagement pieces 36a and 66a. The latch engagement surfaces 35e and 65e or the full latch engagement surfaces 35d and 65d are unlocked. Thereby, the swing door 11 can be opened.

The operation and effect of this embodiment will be described.
(1) In the present embodiment, when the swing door 11 is in the half door state, the upper latch mechanism 60 and the lower latch mechanism 30 can be changed from the half latch state to the full latch state by the actuator 40, and as a result, the swing door 11 is fully closed more accurately. Can be in a state. Further, since the actuator 40 may be shared by the upper latch mechanism 60 and the lower latch mechanism 30, for example, compared to a case where the actuators are individually provided in the upper latch mechanism 60 and the lower latch mechanism 30, the weight and cost of the entire apparatus are increased. Can be suppressed.

  (2) In this embodiment, it is possible to operate the upper latch mechanism 60 and the lower latch mechanism 30 so that the upper latch mechanism 60 and the lower latch mechanism 30 are both changed from the half latch state to the full latch state by the rotation of the electric motor 41 in one direction. It is. Therefore, for example, the time required for the operation can be further shortened as compared with the case where the upper latch mechanism 60 and the lower latch mechanism 30 are selectively operated according to the rotation direction of the electric motor 41. Alternatively, since it is possible to operate both the upper latch mechanism 60 and the lower latch mechanism 30 without switching the rotation direction of the electric motor 41, the rotation control of the electric motor 41 can be further simplified.

  (3) In this embodiment, the close lever 45 has the pressing piece 47a and the cable lead-in portion 49, so that it can have two functions (operation of the upper latch mechanism 60 and operation of the lower latch mechanism 30) in one part. . For this reason, an increase in the number of parts can be suppressed, and as a result, the entire apparatus can be further downsized. And the mountability in the swing door 11 with a limited space can be further improved.

  (4) In the present embodiment, the lower closer 20 and the like can be centrally arranged at the lower end of the swing door 11 by providing the actuator 40 in the lower closer 20 and omitting the drive cable for operating the lower latch mechanism 30.

  (5) In this embodiment, the output of the actuator 40 can be stopped by transmitting the operating force of the operating handle 15 to the cancel lever 44 via the remote controller 16 and the cancel cable C2. Therefore, when the swing door 11 is closed from the half door state, if the operation handle 15 is operated, the operations of the lower latch mechanism 30 and the upper latch mechanism 60 can be stopped simultaneously, and a quick response in an emergency can be realized.

This embodiment can be implemented with the following modifications. The present embodiment and the following modifications can be implemented in combination with each other within a technically consistent range.
In the above embodiment, the cable lead-in portion 49 may be provided on an appropriate lever that transmits the rotation of the electric motor 41 independently of the close lever 45. Alternatively, the cable lead-in portion 49 may be provided on an appropriate lever to which the rotation of the electric motor 41 is transmitted via the close lever 45.

  In the above-described embodiment, the drive cable C4 is used for pulling the upper latch mechanism 60. However, instead of this, an appropriate link (for example, a metal rod-like member) as a connecting member may be used.

  In the above embodiment, the actuator 40 may be provided in the upper closer 50. In this case, the power of the actuator 40 may be transmitted to the upper latch mechanism 60 without passing through the drive cable (C4).

  In the embodiment, the power of the actuator 40 may be transmitted to the lower latch mechanism 30 via a drive cable conforming to the drive cable C4. In this case, the actuator 40 may be provided at an appropriate position in the swing door 11.
