Japanese Patent No. 3591349

  In Patent Document 1, the operation of the inside handle and the outside handle is detected by a common handle switch, and the configuration of the electrical system is simplified. On the other hand, there is a problem that the structure is complicated by interposing a lever for operating the switch between each of the inside handle and the outside handle and the switch. In addition, if the number of parts increases in the transmission path of the operating force from each handle, the operation accuracy of the switch may be affected by the accumulation of part errors. From this point of view, it is preferable that the inside handle and the outside handle directly press the switch, but it is difficult to arrange the two handles so close to each other in terms of layout.

  The present invention has been made in view of the above problems, and provides a door lock control device that detects operation of two unlocking operation handles with a common switch with a simple configuration that does not restrict the arrangement of the handles. For the purpose.

  The door lock control device according to the present invention includes a lock mechanism that restricts the opening and closing of the door and a lock mechanism that is unlocked to allow the door to open and close, and a lock mechanism that unlocks the lock mechanism by a rotation operation about the first axis. An operation handle, an unlocking lever that is supported rotatably about a second axis orthogonal to the first axis, and that is unlocked by the second operation handle to unlock the lock mechanism; A common switch that detects the operation of the first operation handle and the second operation handle, a switch operation unit that is provided on the first operation handle and that directly presses the common switch when an unlocking operation is performed, and unlocking It is provided between the lever and the common switch, and has a transmission means for pressing the common switch by turning the unlocking lever in the unlocking direction.

  As a transmission means provided between the unlocking lever and the common switch, for example, it is supported on the first shaft so as to be rotatable coaxially with the first handle, and relay rotation for orthogonally converting the rotational force of the unlocking lever A member can be used. The relay rotating member is provided with a pressed portion that is pressed by the pressing portion of the unlocking lever, and a switch operation portion that presses the common switch when the pressed portion is pressed and rotated. In this case, the second axis that is the rotation center of the unlocking lever may be at a position different from the extension of the first axis that is the rotation center of the first operation handle.

  Alternatively, as a transmission means, a switch operation part that directly presses the common switch can be formed on the unlocking lever, and the number of parts can be further reduced.

  INDUSTRIAL APPLICABILITY The present invention is suitable for a door lock control device including a fully closed lock mechanism that restricts an opening operation from a fully closed state of the door and a fully open lock mechanism that restricts a closing operation from the fully open state of the door. The unlocking lever performs the unlocking operation of the fully-closed locking mechanism by turning in the unlocking direction. The first operation handle unlocks the fully-closed lock mechanism via the unlocking lever by turning in the first direction from the neutral position, and is fully opened by turning in the second direction from the neutral position. The mechanism is unlocked. The first operation handle is provided with two switch operation units that operate the common switch by rotation in the first direction and rotation in the second direction.

  According to the present invention described above, the door lock control device that detects the operation of the two unlocking operation handles with a common switch can be obtained with a simple configuration that does not restrict the arrangement of the handles.

  1, the slide door 10 is supported so as to be slidable in the front-rear direction between a fully closed position for closing a body opening formed in the vehicle body 12 and a fully open position for opening the body opening. A fully-closed lock mechanism 14 that holds the slide door 10 in the fully-closed position and a fully-open lock mechanism 16 that holds the slide door 10 in the fully-open position are provided. Each lock mechanism is a known structure, and includes a holding member operable at a lock position for holding a held member provided on the vehicle body 12 side and an unlocked position for releasing the held member. When the sliding door 10 is locked at the locking position, sliding of the sliding door 10 is restricted, and when the holding member is moved to the unlocking position, the sliding door 10 can be slid.

  By operating an inside handle (first operation handle) 18 provided on the inside of the slide door 10 and an outside handle (second operation handle) 20 provided on the outside, the fully-closed lock mechanism 14 and the fully-open lock mechanism 16 are operated. Unlock operation can be performed. A remote control mechanism 22 is provided as means for transmitting operation inputs of the inside handle 18 and the outside handle 20 to the fully closed lock mechanism 14 and the fully open lock mechanism 16.

  2 to 5 show a schematic structure of the remote control mechanism 22. The remote control mechanism 22 is configured by assembling each member shown in FIG. 2 to a base plate 24 (see FIG. 9) fixed to the inner panel of the slide door 10. 2 and 3 show the remote control mechanism 22 as viewed from the inside of the vehicle, and FIG. 3 shows the base plate 24 in a perspective view. FIG. 4 shows the remote control mechanism 22 as viewed from the outside of the vehicle.

  The inside handle 18 is supported so as to be tiltable with respect to the base plate 24 about a handle shaft 18x (first shaft). The axis of the handle shaft 18x is generally directed vertically when the slide door 10 is assembled to the vehicle body 12. As shown in FIGS. 15 to 22, the inside handle 18 has a gripping portion 18 b facing the vehicle inside and an operation leg portion 18 c facing the vehicle outside, with a shaft support portion 18 a supported by the handle shaft 18 x interposed therebetween. It is a molded product. A pressing portion 18d is formed at the distal end portion of the operation leg portion 18c. The inside handle 18 can be tilted in the forward and reverse directions with reference to the initial position (neutral position) shown in FIGS. 15 and 18, and when tilted in the direction shown in FIGS. The unlocking operation is performed, and the tilting operation in the direction shown in FIG. The former tilt position of the inside handle 18 is called an opening operation position, and the latter tilt position is called a closing operation position. The inside handle 18 is held at an initial position by a handle holding spring 19.

  The base plate 24 has a control lever (unlocking lever) that can rotate around a lever shaft (second shaft) 26x whose axis is oriented in a direction substantially perpendicular to the handle shaft 18x (the thickness direction of the slide door 10). 26 and an opening lever 28 that is rotatable coaxially with the control lever 26 are supported. The lever shaft 26x is provided at a position different from the extension of the handle shaft 18x. The control lever 26 and the door opening lever 28 are respectively rotated clockwise (counterclockwise in FIG. 4) in FIGS. 2, 3, and 6 to 8 by urging springs 27 and 29 stretched between the base plate 24 and the lever. It is urged to rotate.

  As shown in FIG. 10, the control lever 26 includes a pressed arm portion 26a and a rotation transmitting arm portion 26b that extend in a direction substantially orthogonal to the vicinity of the shaft hole 26s that is pivotally supported by the lever shaft 26x. A side wall of the pressed arm portion 26a is provided with a standing wall 26c that is bent in a direction along the axis of the lever shaft 26x (see FIGS. 5, 15, and 16), and a lock pin is provided on the rotation transmitting arm portion 26b. A control hole 31 is formed. As shown in FIGS. 15 and 16, the standing wall 26c of the control lever 26 is located on an extension of the movement trajectory of the operation leg 18c when the inside handle 18 is tilted to the opening operation position, and is pressed against the standing wall 26c. The portions 18d have different positions in the direction along the axis of the lever shaft 26x. The control lever 26 further includes a pressing protrusion (transmitting means, pressing portion) 26e that protrudes laterally from the rotation transmitting arm portion 26b. The pressing protrusion 26e has a shape bent in a direction approaching the pressed arm portion 26a, and its tip has a standing wall shape bent in a direction along the axis of the lever shaft 26x.

  The lock pin control hole 31 includes an idling hole portion 31a formed toward the rotation direction of the control lever 26 with the shaft hole 26s (lever shaft 26x) as a center, and a rotation radius direction with the lever shaft 26x as a center. It has the rotation transmission hole part 31b formed facing. The control lever 26 is also formed with a rod connecting portion 26d at a portion opposite to the rotation transmitting arm portion 26b across the lever shaft 26x.

  As shown in FIG. 11, the opening lever 28 includes a rotation transmission arm portion 28a extending from a shaft hole 28s supported by the lever shaft 26x, and a cable extending in a direction substantially orthogonal to the rotation transmission arm portion 28a. A connecting arm portion 28b is provided. The rotation transmission arm portion 28a overlaps with the rotation transmission arm portion 26b of the control lever 26, and the rotation transmission hole 33 is formed in the rotation radial direction centering on the shaft hole 28s (lever shaft 26x). Is formed. A latch cable K1 is connected to the tip of the cable connection arm portion 28b. The latch cable K1 is connected to an open lever (not shown) constituting the fully-closed lock mechanism 14, and when the door opening lever 28 rotates against the biasing force of the biasing spring 29 as shown in FIG. The latch cable K1 is pulled to rotate the open lever of the fully closed lock mechanism 14 in the unlocking direction. The lock state of the fully-closed lock mechanism 14 is released by turning the open lever in the unlocking direction.

  The lock pin 30 is inserted into the lock pin control hole 31 and the rotation transmission hole 33. When the lock pin 30 is pivotally supported on the base plate 24, the lock pin 30 is moved along the rotation transmission hole 33 along the link transmission position shown by a solid line in FIG. 6 and the link release shown by a two-dot chain line in FIG. Move to the position. The lock pin lever 35 is rotated by an operation of a lock operation member (not shown) provided on the slide door 10. The lock pin 30 is located in the rotation transmission hole 31b of the lock pin control hole 31 at the linkage position, and the control lever 26 and the door opening lever 28 extend in the extending direction of the rotation transmission hole 31b and the rotation transmission hole 33. Are in a positional relationship that makes the two substantially parallel. When the control lever 26 is rotated here, the force is transmitted to the lock pin 30 through the inner surface of the rotation transmission hole 31b, and the inner surface of the rotation transmission hole 33 is pressed by the lock pin 30, thereby opening the door. The lever 28 rotates together with the control lever 26. On the other hand, the lock pin 30 is located in the idle swing hole 31a of the lock pin control hole 31 at the linkage release position, and when the control lever 26 rotates against the biasing force of the biasing spring 27, the lock pin 30 is locked. The control lever 26 transmits the rotational force to the door opening lever 28 while staying at a fixed position without receiving the pressing force by the inner surface of the pin control hole 31 and changing the relative position of the lock pin 30 in the idle swing hole 31a. Rotate alone (missing) without any problems.

  When the inside handle 18 is operated from the initial position to the opening operation position, the operating force is transmitted to the control lever 26 via the power transmission pin 32. The power transmission pin 32 is a synthetic resin molded product, and is supported so as to be slidable with respect to the interlock control hole 34 formed in the base plate 24. As shown in FIG. 9, the interlock control hole 34 is an L-shaped hole having a rectilinear guide hole 34a and an escape hole 34b. The rectilinear guide hole 34a is formed in a direction along the movement trajectory of the operation leg 18c (pressing part 18d) when the inside handle 18 is tilted to the opening operation position, and the escape hole 34b is substantially orthogonal thereto. It is formed in the direction.

  As shown in FIGS. 12 to 14, the power transmission pin 32 includes a slide shaft portion 32a that is slidably inserted into the interlock control hole 34, and a pressure transmission portion 32b that is positioned coaxially with the slide shaft portion 32a. And a pair of flanges 32c and 32d provided to be separated from each other in the axial direction of the slide shaft portion 32a. The slide shaft portion 32a and the press transmission portion 32b each have a cylindrical shape, and the press transmission portion 32b has a larger diameter than the slide shaft portion 32a. The flanges 32c and 32d have a disk shape larger in diameter than the pressure transmission portion 32b, and the base plate 24 is sandwiched between the flanges 32c and 32d, so that the power transmission pin 32 is prevented from falling off from the interlock control hole 34. . Further, when the power transmission pin 32 moves while being guided by the interlock control hole 34, the fall is restricted by the flange 32c and the flange 32d. In other words, the portion inserted between the flange 32c and the flange 32d in the slide shaft portion 32a is slidably inserted into the interlock control hole 34.

  The slide shaft portion 32 a of the power transmission pin 32 is further slidably inserted into a long hole 36 a formed in the cancel lever 36. As shown in FIGS. 15 and 16, the cancel lever 36 is extended along the flange 32 d of the power transmission pin 32, and the cancel lever 36 is located in a region opposite to the press transmission portion 32 b with the base plate 24 interposed therebetween. The slide shaft portion 32a is held. The cancel lever 36 is supported on the base plate 24 so as to be rotatable about a lever shaft 36x parallel to the lever shaft 26x, and the long hole 36a is formed in a turning radial direction about the lever shaft 36x. It is a long hole. The cancel lever 36 can rotate (swing) between the transmission position shown in FIGS. 6 and 8 and the cancel position shown in FIG. 7, and the long hole 36 a is a straight guide of the interlock control hole 34 at the transmission position. It is positioned so as to overlap with the hole 34a, and in the cancel position, the vicinity of the tip of the long hole 36a is positioned so as to overlap with the escape hole 34b of the interlock control hole 34.

  When the cancel lever 36 is rotated, the slide shaft portion 32a of the power transmission pin 32 moves in the escape hole portion 34b of the interlock control hole 34, and when the cancel lever 36 is in the transmission position, the linear guide hole portion 34a The power transmission pin 32 is held at the boundary portion of the escape hole 34b. The position of the power transmission pin 32 at this time is called a linkage position. In the linkage position, as shown in FIGS. 4, 6, 8, 15, and 16, the pressure transmission portion 32 b of the power transmission pin 32 is provided between the pressure portion 18 d of the inside handle 18 and the standing wall 26 c of the control lever 26. Be positioned. The pressing portion 18d and the standing wall 26c have different positions in the direction along the lever shaft 26x, but the pressing transmission portion 32b has a length that covers the phase of the pressing portion 18d and the standing wall 26c. While the standing wall 26c is brought into contact with the vicinity of the boundary between the pressure transmission part 32b and the flange 32d, the vicinity of the tip part of the pressure transmission part 32b is positioned on the movement locus of the pressure part 18d. Therefore, when the inside handle 18 is tilted to the opening operation position (counterclockwise in FIG. 15), as shown in FIG. 16, the pressing portion 18d presses the pressing transmission portion 32b, and the power transmission pin 32 (slide shaft portion 32a). ) Is moved along the rectilinear guide hole 34a and the long hole 36a in the approaching direction to the lever shaft 36x. In response to this, the pressure transmitting portion 32b presses the standing wall 26c, and the control lever 26 is rotated counterclockwise against the urging force of the urging spring 27 as shown in FIG.

  In this way, when the operating force to the opening operation position of the inside handle 18 is transmitted to the control lever 26 via the power transmission pin 32 in the linkage position, the power transmission pin 32 is a pressing transmission portion that is one end portion in the axial direction. The vicinity of the tip of 32b is pressed by the pressing portion 18d, and the pressing force is transmitted to the standing wall 26c that abuts near the center in the axial direction. For this reason, a force that causes the power transmission pin 32 to tilt in the counterclockwise direction in FIGS. 15 and 16 acts around the support portion by the base plate 24, but the inclination is prevented by the flanges 32c and 32d. Can move smoothly.

  On the other hand, when the cancel lever 36 is rotated from the transmission position to the cancellation position as shown in FIG. 7, the power transmission pin 32 (slide shaft portion 32a) slides in the direction away from the rectilinear guide hole portion 34a in the escape hole portion 34b. Then, the pressure transmitting portion 32b is retracted from a position (on the movement locus of the pressing portion 18d) between the pressing portion 18d of the inside handle 18 and the pressed arm portion 26a of the control lever 26. The position of the power transmission pin 32 at this time is called a linkage release position. In the linkage release position, even if the inside handle 18 is rotated counterclockwise in FIG. 15, the pressing portion 18 d does not come into contact with the power transmission pin 32 (press transmission portion 32 b) and moves to the opening operation position of the inside handle 18. The operating force is not transmitted to the control lever 26.

  As shown in FIGS. 3 and 4, the remote control mechanism 22 further includes an outside handle link lever 38 and a door closing lever 40. The outside handle linkage lever 38 and the door closing lever 40 are respectively supported on the base plate 24 so as to be rotatable about lever shafts 38x and 40x parallel to the lever shaft 26x.

  The outside handle linking lever 38 includes a first arm portion 38a and a second arm portion 38b extending in different directions from a pivotal support portion by the lever shaft 38x, and the first arm portion 38a has an outside handle linking rod R1. The control lever linkage rod R2 and the fully open lock operation rod R3 are connected. The outside handle linkage rod R1 transmits an operating force from the outside handle 20 (FIG. 1) to the outside handle linkage lever 38. When the outside handle 20 is operated in the unlocking direction, the outside handle linkage rod R1. The outside handle linkage lever 38 is rotated counterclockwise in FIG. 3 (clockwise in FIG. 4). The rotation direction of the outside handle linkage lever 38 is referred to as a release direction. Further, an electric lock operation mechanism 42 incorporating a motor is connected to the second arm portion 38b of the outside handle linkage lever 38, and the outside handle linkage lever 38 can be rotated by driving the motor. By operating a remote operation switch (not shown) or an operation switch provided in the driver's seat, the motor of the electric lock operation mechanism 42 is driven, and the outside handle linkage lever 38 is rotated in the release direction via the sector gear mechanism. The control lever linking rod R2 is connected to the rod connecting portion 26d of the control lever 26, and when the outside handle linking lever 38 rotates in the release direction (counterclockwise in FIG. 3, clockwise in FIG. 4), The control lever 26 is rotated via the lever linking rod R2 in a direction against the urging force of the urging spring 27 (counterclockwise in FIGS. 3, 6 to 8, and clockwise in FIG. 4).

  The closing lever 40 is urged to rotate counterclockwise in FIG. 3 and FIGS. 6 to 8 (clockwise in FIG. 4) by an urging spring 44 stretched between the closing lever 40 and the base plate 24. A latch cable K2 is connected to the cable connecting portion 40a of the closing lever 40. The latch cable K2 is connected to an open lever constituting the fully open lock mechanism 16, and when the closing lever 40 rotates in a direction against the urging force of the urging spring 44, the latch cable K2 is pulled to open the fully open lock mechanism. The open lever 16 (FIG. 1) is rotated in the unlocking direction. The lock state of the fully open lock mechanism 16 is released by turning the open lever in the unlock direction.

  The fully open lock operating rod R3 connects the outside handle linkage lever 38 and the rod connecting portion 40b of the closing lever 40, and the outside handle linkage lever 38 is in the release direction (counterclockwise in FIG. 3 and clockwise in FIG. 4). , The door closing lever 40 is rotated in the unlocking direction of the fully open lock mechanism 16 (clockwise in FIG. 3 and counterclockwise in FIG. 4) via the fully open lock operating rod R3. Further, the rod connecting portion 40c of the closing lever 40 and the inside handle 18 are connected by an inside handle linkage rod R4. When the inside handle 18 is tilted from the initial position to the closing operation position, the door closing lever 40 is unlocked by the inside opening handle linkage rod R4 in the unlocking direction of the fully opening lock mechanism 16 (clockwise in FIG. 3, counterclockwise in FIG. 4). Is rotated.

  The remote control mechanism 22 is provided with a switch (common switch) 50 for detecting the operation state of the inside handle 18 and the outside handle 20. The switch 50 is fixed on the base plate 24, and has an elastic contact piece 50a that can be elastically deformed and a fixed contact 50b provided at a position facing the elastic contact piece 50a. The elastic contact piece 50a is separated from the fixed contact 50b in a free state (switch-off state), and contacts the fixed contact 50b by elastic deformation (switch-on state). As shown in FIGS. 17 to 22, the switch 50 is disposed so as to be operable by two members, that is, the inside handle 18 and a switch operation lever (transmission means, relay rotation member) 52. The switch operating lever 52 is supported so as to be rotatable about a handle shaft 18x common to the inside handle 18, and includes a shaft support portion 52a facing the shaft support portion 18a and an offset portion 52b from which a pressed protrusion 52c is projected. have. A spring (not shown) is stretched between the spring hook 52d (FIGS. 21 to 24) and the base plate 24, and the switch operating lever 52 is urged to rotate counterclockwise in FIGS. Has been. 21 and 23 show the initial position of the switch operation lever 52 held by this spring.

  As shown in FIG. 17, the inside handle 18 and the switch operating lever 52 make the shaft supporting portions 18a and 52a come close to each other in the direction along the axis of the handle shaft 18x while separating the operating leg portion 18c and the offset portion 52b. The switch 50 is disposed in this separated space. The inside handle 18 has two wedge-shaped switch operation protrusions (switch operation parts) 18e protruding in the outer diameter direction centering on the handle shaft 18x at the step between the shaft support part 18a and the operation leg part 18c. 18f (FIGS. 18 to 20), and the switch operation lever 52 is formed with a switch operation protrusion (switch operation portion) 52e at a step portion between the shaft support portion 52a and the offset portion 52b. . The elastic contact piece 50a of the switch 50 is provided at a position facing both the switch operation protrusions 18e and 18f on the inside handle 18 side and the switch operation protrusion 52e on the switch operation lever 52 side in the direction along the handle shaft 18x. (FIG. 17).

  The inside handle 18 and the switch operating lever 52 can be independently rotated. When the inside handle 18 is tilted from the initial position shown in FIG. 18 to the opening operation position, the elastic contact piece 50a of the switch 50 is pressed by the switch operation projection 18e to contact the fixed contact 50b as shown in FIG. When tilted from the initial position shown in FIG. 18 to the closing operation position, the elastic contact piece 50a of the switch 50 is pressed and brought into contact with the fixed contact 50b by the switch operation projection 18f as shown in FIG. That is, the switch 50 is operated regardless of which direction the inside handle 18 is tilted.

  When the switch operating lever 52 is in the initial position, as shown in FIG. 23, the pressing protrusion 26e provided on the control lever 26 does not press the pressed protrusion 52c. At this time, the switch operation protrusion 52e of the switch operation lever 52 is separated from the elastic contact piece 50a of the switch 50 (FIG. 21). 24, the pressed protrusion 52c is pressed by the pressing protrusion 26e of the control lever 26, whereby the switch operating lever 52 is rotated counterclockwise from the initial position against the spring biasing force. . When the switch operating lever 52 rotates, the switch operating projection 52e presses the elastic contact piece 50a of the switch 50 to contact the fixed contact 50b as shown in FIG. The rotation direction of the control lever 26 that presses the pressed protrusion 52 c via the pressing protrusion 26 e is a lock releasing direction that causes the lock mechanism 14 to be unlocked via the door opening lever 28.

  The operation of the remote control mechanism 22 having the above structure will be described. The opening operation of the sliding door 10 in the fully closed state (unlocking of the fully closing locking mechanism 14) and the closing operation of the sliding door 10 in the fully opening state (unlocking of the fully opening locking mechanism 16) are respectively performed on the inside handle 18 and the out. It can be operated via the three systems of the side handle 20 and the electric lock operating mechanism 42. Of these, the outside handle 20 and the electric lock operating mechanism 42 have the same operation in the remote control mechanism 22 regardless of the input from either of them, and will be described together.

  When the inside handle 18 is tilted from the initial position to the opening operation position with the slide door 10 fully closed, when the cancel lever 36 is in the transmission position (the power transmission pin 32 is in the linkage position), as described above, the inside handle 18 The pressure transmitting portion 32b of the power transmission pin 32 is pressed by the pressing portion 18d, and the standing wall 26c of the control lever 26 is pressed through the pressure transmitting portion 32b (FIGS. 8 and 16). As a result, the control lever 26 is pressed and rotated from the position of FIG. 6 to the position of FIG. 8 against the urging force of the urging spring 27. Here, when the lock pin 30 is in the linkage position, the opening lever 28 together with the control lever 26 is rotated against the urging force of the urging spring 29 (FIG. 8), and the latch cable K1 is pulled and all of them are pulled. The lock of the closing lock mechanism 14 is released.

  When the cancel lever 36 is in the cancel position, the power transmission pin 32 is held in the linkage release position as shown in FIG. 7, so that even if the inside handle 18 is tilted from the initial position to the opening operation position, the control lever 26 The operating force is not transmitted to. Further, when the lock pin 30 is in the linkage release position, no operating force is transmitted to the door opening lever 28 even if the control lever 26 is pressed and rotated via the power transmission pin 32. Therefore, when either the power transmission pin 32 or the lock pin 30 is in the linkage release position, the lock of the full-close lock mechanism 14 is not performed even if the inside handle 18 is tilted to the opening operation position.

  As the inside handle 18 tilts from the initial position to the opening operation position, the switch operation protrusion 18e presses the elastic contact piece 50a to contact the fixed contact 50b, and the switch 50 is turned on (FIG. 19). . Thereby, the unlocking operation from the inside handle 18 side is detected.

  When the inside handle 18 is tilted from the initial position to the closing operation position with the slide door 10 fully opened, the closing lever 40 is rotated in the clockwise direction in FIG. 6 via the inside handle linkage rod R4, and the latch cable K2 is pulled. Thus, the lock of the fully open lock mechanism 16 is released. At this time, according to the tilt of the inside handle 18, the switch operating projection 18f presses the elastic contact piece 50a to contact the fixed contact 50b and the switch 50 is turned on (FIG. 20), and the lock from the inside handle 18 side is performed. A release operation is detected.

  When the outside handle 20 is operated or the electric lock operating mechanism 42 is driven when the slide door 10 is fully closed or fully opened, the outside handle linkage lever 38 is released in the release direction (counterclockwise in FIG. It rotates in the clockwise direction in FIG. Then, the control lever 26 is rotated to the position shown in FIG. 8 against the urging force of the urging spring 27 via the control lever linking rod R2, and the urging spring 44 is attached via the fully open lock operating rod R3. The closing lever 40 is rotated in the clockwise direction in FIG. 6 against the force. Here, when the slide door 10 is in the fully closed state and the lock pin 30 is in the linkage position, the rotation of the control lever 26 is transmitted to the door opening lever 28 via the lock pin 30 (FIG. 8). The latch cable K1 is pulled by the door opening lever 28, and the lock of the full-close lock mechanism 14 is released. When the slide door 10 is in the fully closed state and the lock pin 30 is in the linkage release position, the rotation of the control lever 26 is not transmitted to the door opening lever 28, and the lock state of the fully closed lock mechanism 14 is maintained. Is done. When the slide door 10 is in the fully open state, the latch cable K2 is pulled by the rotation of the door closing lever 40, and the lock of the fully open lock mechanism 16 is released. In either case, when the control lever 26 is rotated in the unlocking direction via the control lever linkage rod R2, the pressing protrusion 26e presses the pressed protrusion 52c to rotate the switch operating lever 52. (FIG. 24). As a result, the switch operation protrusion 52e presses the elastic contact piece 50a to contact the fixed contact 50b, and the switch 50 is turned on (FIG. 22). Thereby, the unlocking operation from the outside handle 20 or the electric lock operation mechanism 42 side is detected.

  In the remote control mechanism 22 described above, the unlocking operation of the inside handle 18 and the outside handle 20 can be detected by the common switch 50, and the number of parts of the electrical system is reduced to simplify the configuration. Has been achieved. Regarding the detection of the operation of the inside handle 18, since the elastic contact piece 50a of the switch 50 is directly pressed by the switch operation protrusions 18e and 18f formed integrally with the inside handle 18, it is possible to detect the operation without any other components. The operation state of the inside handle 18 can be detected with high accuracy. The operation of the outside handle 20 is transmitted via the control lever 26 and the switch operation lever 52 to the switch 50 provided at a position where it can be directly pressed by the inside handle 18. Therefore, the outside handle 20 can be arranged with a high degree of freedom without being restricted near the switch 50.

  Since the control lever 26 is provided in the vicinity of the switch 50, it is possible to directly press the switch 50 with the control lever 26 without using an operation direction conversion member such as the switch operation lever 52. is there. This second embodiment is shown in FIGS. In the second embodiment, portions common to the previous embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 25, the control lever 26 has a switch operation arm portion (transmission means, switch operation portion) 26f projecting to the side of the rotation transmission arm portion 26b instead of the pressing projection 26e. As shown in FIG. 28, the moving plane of the switch operating arm portion 26f when the control lever 26 is rotated is at the same height position as the elastic contact piece 50a of the switch 50. It contacts / separates with respect to the piece 50a. When the control lever 26 is in the initial position where it is not rotated in the unlocking direction as shown in FIG. 26, the switch operating arm portion 26f is separated from the elastic contact piece 50a (FIG. 29). When the control lever 26 is rotated in the unlocking direction as shown in FIG. 27, the switch operating arm 26f comes into contact with and presses the elastic contact piece 50a to turn on the switch 50 (FIG. 30). According to this configuration, since the control lever 26 directly presses the elastic contact piece 50a of the switch 50 without using an operation direction changing member such as the switch operating lever 52, the number of parts is further reduced and the structure is simple and highly accurate. Switch operation is possible.

  In the aspect in which the switch operating arm portion 26f of the control lever 26 directly presses the elastic contact piece 50a of the switch 50, the rotation of the control lever 26 is extended on the extension of the handle shaft 18x that is the rotation center of the inside handle 18. It is preferable to position the lever shaft 26x as the center and the switch operation arm portion 26f in the control lever 26. Specifically, in the state of FIG. 27, the switch operating arm portion 26f is positioned on the extension of the handle shaft 18x, but the lever shaft 26x may be positioned on the extension of the handle shaft 18x.

  The present invention is not limited to the illustrated embodiment. For example, unlike the illustrated embodiment, the control lever 26 can be applied directly to the latch cable K1 as the operating force transmission means for the fully-closed lock mechanism 14 without using the door opening lever 28. In this aspect, the second cancel mechanism configured by the lock pin 30, the lock pin control hole 31, and the rotation transmission hole 33 in the illustrated embodiment is not provided. On the contrary, a configuration in which two or more cancel mechanisms are provided between the control lever 26 and the fully closed lock mechanism 14 is also possible. Specifically, an arbitrary number of intermediate levers corresponding to the control lever 26 are arranged between the control lever 26 and the opening lever 28 in the illustrated embodiment, and the lock pin 30, the lock pin control hole 31, etc. A canceling mechanism such as the rotation transmission hole 33 may be provided.
