As a vehicle slide door device, there is a device in which the slide door is opened and closed by an opening / closing actuator such as a drive motor. This type of sliding door device comprises a door locking mechanism that locks the sliding door in the closed state, and an unlocking actuator that unlocks the door locking mechanism when the door is opened. In this sliding door device, when the switch is opened while the sliding door is closed and locked, the unlocking actuator unlocks the door lock mechanism, and then the opening / closing actuator opens the sliding door. Manipulate.

Further, this type of slide door device can be opened by an operation handle instead of a switch, but recently, the operation handle is being omitted in order to reduce the weight and cost. In this case, in consideration of an emergency in which the actuator becomes inoperable due to a failure of the power supply system or the like, an emergency unlock operation unit for manually unlocking the door lock mechanism in an emergency is provided (see, for example, Patent Document 1). ).

In the slide door device described in Patent Document 1, the emergency unlocking operation portion is arranged inside the opening of the door trim, and the opening is usually covered with a lid member. This prevents easy access to the emergency unlock operation unit (erroneous operation of the emergency unlock operation unit) in normal times.

Japanese Unexamined Patent Publication No. 2001-98819

In the sliding door device described in Patent Document 1, the passenger compartment side of the emergency unlocking operation unit is hidden by a removable lid member. Therefore, it is possible to prevent an erroneous operation of the emergency lock release unit in a normal time, but it is difficult to quickly access the emergency lock release unit in an emergency.

Therefore, the present invention will provide a vehicle sliding door device that can prevent door unlocking due to an erroneous operation of the emergency unlocking operation unit and can quickly access the emergency unlocking operation unit from the vehicle interior in an emergency. Is to be.

The vehicle sliding door device according to the present invention adopts the following configuration in order to solve the above problems.
That is, the vehicle slide door device according to the present invention has a slide door (for example, the slide door 18 of the embodiment) that slides open and closes the door opening of the vehicle body (for example, the door opening 12 of the embodiment) and the slide door of the embodiment. An opening / closing actuator (for example, the door drive motor 21 of the embodiment), a door lock mechanism for locking the sliding door in the closed state (for example, the fully closed latch mechanism 35 of the embodiment), and when the door of the sliding door is opened. , An unlocking actuator (for example, the releaser motor 37 of the embodiment) for unlocking the door lock mechanism, and an emergency provided on the passenger compartment side of the sliding door to manually unlock the door lock mechanism in an emergency. A vehicle sliding door device including an emergency unlock operation unit (for example, the emergency inner release operation unit 24 of the embodiment), wherein the emergency unlock operation unit does not allow the unlock operation. It is characterized by having a multi-stage operation mechanism (for example, the multi-stage operation mechanism 100 of the embodiment) for the second operation of the subsequent stage that allows the first operation and the unlock operation.

With the above configuration, the sliding door is normally opened and closed by the opening / closing actuator. When the sliding door is completely closed, the door locking mechanism locks the sliding door in the closed state. When the unlocking actuator is activated by operating a switch or the like from this state, the lock by the door lock mechanism is released.
On the other hand, when the door lock mechanism cannot be unlocked by the unlocking actuator due to a failure of the electric system or the like, the occupant can manually operate the emergency unlocking operation unit. At this time, when an operating force is applied to the emergency lock release operation unit and the first operation of the previous stage is performed by the multi-stage operation mechanism, the second operation (unlock operation) of the rear stage can be executed by the multi-stage operation mechanism thereafter. become. Therefore, even if the emergency lock release operation unit is accidentally first operated, the function of the multi-stage operation mechanism can prevent the door lock mechanism from being suddenly released.

The emergency lock release operation unit may stop the operation of the opening / closing actuator by the first operation.
In this case, even if the opening / closing actuator is in the operating state when the occupant mistakenly performs the first operation on the emergency lock release operation unit, the slide door is opened by the opening / closing actuator. It can be surely prevented from being damaged. Therefore, in the case of this configuration, the safety of the occupant can be further enhanced.

The emergency lock release operation unit may activate the alarm device by the first operation.
In this case, when the emergency lock release operation unit is erroneously first operated by the occupant, the alarm device is activated to notify the occupant of that fact. Therefore, it is possible to prevent the door lock mechanism from being accidentally released by the occupant.

The emergency lock release operation unit may be configured to have a detection switch (for example, the detection switch 80 of the embodiment) for detecting that the first operation has been performed.
In this case, since it is possible to instantly detect that the first operation has been performed by the occupant by the detection switch, it is possible to quickly take measures such as stopping the operation of the opening / closing actuator and operating the warning device.

The emergency lock release operation unit has a rotatable operation lever (for example, the operation lever 70 of the embodiment), and the operation lever is a door trim on the passenger compartment side of the slide door (for example, the door trim of the embodiment). The operation lever is arranged in the opening provided in 49) (for example, the opening 50 of the embodiment), and the operation lever is further exposed to the vehicle interior side through the opening (for example, the design surface 75a of the embodiment). -1) and a regulation unit (for example, a regulation unit 77a of the embodiment) that abuts on the back surface of the door trim when the operation lever is in the initial position and aligns the design surface with the vehicle interior side surface of the door trim. , May be provided.
In this case, when the regulating portion abuts on the back surface of the door trim, the design surface of the operating lever and the side surface of the vehicle interior of the door trim are aligned, so that the appearance from the vehicle interior side is improved. Further, since the operation lever can be operated by touching the design surface in the opening of the door trim, the access to the operation lever from the vehicle interior is improved.

The emergency lock release operation unit is attached to the door trim and has a holder (for example, the holder 71 of the embodiment) that rotatably holds the operation lever, and the operation lever is rotatable to the holder. The holder is provided with a lever main body portion (for example, the lever main body portion 66 of the embodiment) held in the lever main body portion and a regulation lever (for example, the regulation lever 77 of the embodiment) held so as to be able to advance and retreat to the lever main body portion. Is a stopper portion (for example, a stopper portion) that abuts on the restricting lever in the forward state and restricts the rotation of the lever main body portion at the end position of the first operation during the rotation operation of the lever main body portion from the initial position. The first protrusion 96) of the embodiment is provided, and the emergency lock release operation portion is the lever main body portion for unlocking operation by retracting the regulation lever in contact with the stopper portion from the stopper portion. It may be one that allows further rotation of.
In this case, when the door lock mechanism is unlocked by the operation lever of the emergency lock release operation unit, the operation lever main body portion is rotated until the regulation lever in the forward position comes into contact with the stopper portion of the holder. After that, by retracting the regulation lever, the contact with the stopper portion of the regulation lever is released. If the operation lever main body is further rotated in this state, the door lock mechanism is unlocked. Therefore, with the above configuration, it is possible to obtain a reliable multi-stage operation in the emergency unlock operation unit.

The unlocked portion of the door lock mechanism (for example, the operation link 38 of the embodiment) is linked to the lever main body portion by a releaser cable (for example, the releaser cable 45 of the embodiment), and is linked to the releaser cable of the lever main body portion. The connecting portion of the lever body is arranged at a position separated from the rotation axis of the lever body (for example, the support pin 74 of the embodiment) in the longitudinal direction of the lever body, and the releaser cable has the lever body. It may have a play in which the operating force is not transmitted to the unlocked portion until the rotation operation is performed beyond the stopper portion.
In this case, since the releaser cable has play, the unlocking portion of the door lock mechanism is not released until the rotation of the lever main body portion is restricted by the stopper portion. Therefore, in the situation of the first operation until the rotation of the lever main body portion is restricted by the stopper portion, the lock of the door lock mechanism is not released.

The rotation shaft may be arranged in a region of the lever body portion closer to the center than the longitudinal end portion of the design surface.
In this case, the occupant can easily rotate the lever main body by pushing one end of the lever main body in the longitudinal direction from the passenger compartment side into the opening. Further, at this time, if necessary, the other end side of the lever main body portion in the longitudinal direction can be pulled toward the passenger compartment side. When this configuration is adopted, it is not necessary to provide a grip portion protruding toward the vehicle interior side in the lever main body portion, so that the appearance of the lever main body portion from the vehicle interior side can be improved.

The emergency lock release operation unit includes a rotatable operation lever (for example, the operation lever 70 of the embodiment) and a holder for holding the operation lever rotatably (for example, the holder 71 of the embodiment). The operating lever is arranged in an opening (for example, the opening 50 of the embodiment) provided in the door trim (for example, the door trim 49 of the embodiment) on the passenger compartment side of the sliding door, and the holder is placed. It may be screwed and fixed to the boss portion (for example, the boss portion 55 of the embodiment) projecting from the back surface of the door trim.
In this case, the operation lever can be easily installed on the door trim by screwing the holder to which the operation lever is attached to the boss portion on the back surface of the door trim.

The unlocked portion of the door lock mechanism is linked to the lever main body portion by a releaser cable (for example, the releaser cable 45 of the embodiment), and the lever main body portion is an operation block having the design surface (for example, of the embodiment). The operation block 75) and a cable connecting block (for example, the cable connecting block 76 of the embodiment) to which one end is rotatably held by the holder and the releaser cable is connected to the other end are provided. The operation block includes a plate-shaped portion having the design surface (for example, the plate-shaped portion 75a of the embodiment) and a pair of side walls protruding in the back surface direction from the side end portion in the width direction intersecting the longitudinal direction of the plate-shaped portion. The cable connecting block is integrally assembled to the pair of the side wall portions, and the pair of the side wall portions together with one end of the cable connecting block is the holder. It may be held rotatably.
In this case, a cable connecting block that is rotatably held by the holder and operates the releaser cable is integrally assembled to a pair of side wall portions of the operation block. Therefore, the rigidity of the entire lever body is increased. Therefore, the releaser cable can be smoothly pulled in by rotating the lever body.

The unlocked portion of the door lock mechanism is linked to the lever main body portion by a releaser cable (for example, the releaser cable 45 of the embodiment), and the outer tube of the releaser cable (for example, the outer tube of the embodiment) is attached to the holder. A concave-groove-shaped tube fixing portion (for example, the tube fixing portion 98 of the embodiment) for fixing 45o) is provided, and the concave-groove-shaped opening of the tube fixing portion (for example, the opening 98a of the embodiment) is the said. It may be blocked by a wall of the door trim (eg, wall 49a of the embodiment).
In this case, by fixing the outer tube of the releaser cable to the concave groove-shaped tube fixing portion of the holder and fixing the holder to the door trim in that state, it is possible to prevent the outer tube from coming off from the tube fixing portion. Therefore, when this configuration is adopted, it is possible to stably fix the outer tube to the holder and facilitate assembly.

A child lock device (for example, the child lock device 101 of the embodiment) for prohibiting the opening operation of the slide door from the passenger compartment side is further provided, and the emergency lock release operation unit and the lock release unit of the door lock mechanism are provided. In the meantime, when the slide door is in an operation prohibited state by the child lock device, a blocking mechanism (for example, of the embodiment) that blocks the operation transmission from the emergency unlocking operation unit to the unlocking unit. A cutoff mechanism 108) may be provided.
In this case, when the child lock device is in the off state (the operation of the sliding door is not prohibited), when the emergency lock release operation unit is operated in multiple stages, the operation force is transmitted to the lock release unit of the door lock mechanism. .. As a result, the door lock mechanism is unlocked. On the other hand, when the child lock device is on (the operation of the slide door is prohibited), even if the emergency lock release operation unit is operated in multiple stages, the operation transmission of the operation force to the lock release unit is blocked by the cutoff mechanism. NS. As a result, the door lock mechanism is not unlocked. Therefore, when the child lock device is on, for example, even if a child in the vehicle interior unintentionally operates the emergency lock release operation unit, the door lock mechanism is not released.

In the present invention, since the emergency unlock operation unit has a multi-stage operation mechanism that allows the lock release operation of the rear stage only after the first operation of the front stage is performed, the emergency lock release operation unit is erroneously operated. Even if there is, it is possible to prevent the door lock mechanism from being suddenly released. Therefore, according to the present invention, it is possible to prevent the door lock release due to an erroneous operation of the emergency lock release operation unit, and the emergency lock release operation unit is arranged facing the vehicle interior side without being covered with a separate lid member. Since it is possible, the emergency unlocking operation unit can be quickly accessed from the passenger compartment in an emergency.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the arrow FR points to the front of the vehicle 10, the arrow UP points to the upper side of the vehicle 10, and the arrow LH points to the left side of the vehicle.

FIG. 1 is a conceptual diagram of a vehicle 10 of an embodiment provided with a sliding door 18. In FIG. 1, the left side surface of the vehicle 10 and the internal structure of the slide door 18 on the left side are also shown.
As shown in FIG. 1, the vehicle 10 includes a slide door 18 that opens and closes the door opening 12 of the side portion 11a of the vehicle body 11, and a slide door 18 that moves in the vehicle body front-rear direction and is in a fully open / fully closed position. It includes a door actuation system 20 that locks and unlocks. The sliding door 18 and the door operating system 20 constitute the sliding door device of the present embodiment.

A first fully closed striker 13 is provided at the rear of the door opening 12 of the vehicle body 11. A fully open striker 14 is provided at the lower rear portion of the door opening 12 of the vehicle body 11. A second fully closed striker 15 is provided at the front of the door opening 12 of the vehicle body 11. The first fully closed striker 13, the fully open striker 14, and the second fully closed striker 15 are formed so as to be restrainable by a latch mechanism, similar to the striker generally used for a vehicle door.

The door operation system 20 includes a door drive motor 21, a fully closed latch unit 22, a fully open hook mechanism 23, an emergency inner release operation unit 24, an emergency outer release operation unit 25, a front hook mechanism 26, and opening / closing. It includes a switch 31, an indoor switch 27, and an outdoor switch 28. In the present embodiment, the emergency inner release operation unit 24 constitutes the emergency lock release operation unit.

The door drive motor 21 constitutes an opening / closing actuator that opens and closes the door opening 12 by moving the sliding door 18 in the front-rear direction of the vehicle body. The door drive motor 21 is arranged at a rear portion of the door opening 12 on the side of the vehicle body and is driven by the open / close switch 31. The open / close switch 31 is provided, for example, at a location (for example, in the vicinity of the steering wheel) that can be operated by the driver seated on the driver's seat. The door drive motor 21 has the same configuration as a drive motor generally used for a power slide door. That is, the door drive motor 21 operates the drive cable by rotating the drum in the forward rotation direction and the reverse rotation direction by operating the switch in the opening direction and the closing direction of the open / close switch 31. At this time, the slider connected to the drive cable is guided by the center rail 34 and moves in the front-rear direction of the vehicle body. As a result, the slide door 18 supported by the slider moves (slides) in the front-rear direction of the vehicle body to open and close the door opening 12 on the side of the vehicle body.
Here, when the slide door 18 is closed, the slider moves on the general portion (portion extending in the front-rear direction of the vehicle body) 34a of the center rail 34 from the initial stage to the middle stage of the closing operation. Further, in the latter stage of the closing operation, the slider moves the retracted portion (the portion extending inward in the vehicle width direction) 34b of the center rail 34.

FIG. 2 is a conceptual diagram showing a fully closed latch unit 22, an emergency inner release operation unit 24, and an emergency outer release operation unit 25.
As shown in FIG. 2, the fully closed latch unit 22 is arranged at the rear portion 18a of the slide door 18. The fully closed latch unit 22 includes a fully closed latch mechanism 35 (door lock mechanism) and a releaser device 36.

The fully closed latch mechanism 35 has the same configuration as the latch mechanism generally used for vehicle doors, and has a state of restraining the first fully closed striker 13 (see FIG. 1) (locked state) and a first fully closed striker. It is possible to switch between a state in which the restraint of 13 is released (unlocked state) and a state in which the restraint is released. Specifically, when the slide door 18 is closed by the door drive motor 21, the fully closed latch mechanism 35 switches from the half-latch state to the full-latch state in the later stage of the closing operation of the slide door 18. In the full latch state using the closer motor as needed, the latch and ratchet of the fully closed latch mechanism 35 restrain (lock) the first fully closed striker 13 and hold the slide door 18 in the fully closed position.

On the other hand, the fully closed latch mechanism 35 is unlocked by the releaser motor 37 of the releaser device 36 when the slide door 18 opens the door opening 12. That is, when the releaser motor 37 is driven when the slide door 18 opens the door opening 12, the ratchet of the fully closed latch mechanism 35 is released from the state (locked state) of holding the first fully closed striker 13. It can be switched to the released state).
In the present embodiment, the releaser motor 37 constitutes the unlocking actuator.

The releaser device 36 includes a releaser motor 37 and an operation link 38 rotatably supported by a support shaft 39 of the support base. The releaser motor 37 and the operation link 38 are interlocked with each other via the releaser cable 41. The operation link 38 is rotated in one direction by receiving the driving force of the releaser motor 37. Further, the fully closed latch mechanism 35 and the operation link 38 are interlocked with each other via a releaser cable 42.

The releaser motor 37 is driven and operated by an open / close switch 31 (see FIG. 1). The releaser device 36 rotates the operation link 38 in the counterclockwise direction in FIG. 2 by the releaser motor 37 by opening the open / close switch 31. When the operation link 38 rotates counterclockwise in this way, a pulling force acts from the operation link 38 to the ratchet of the fully closed latch mechanism 35 via the releaser cable 42, and as a result, the latch of the fully closed latch mechanism 35 becomes the first. 1 The fully closed striker 13 is switched from a restrained state (locked state) to an released state (unlocked state).
In the present embodiment, the operation link 38 constitutes an unlocking portion of the door lock mechanism.

The releaser motor 37 that unlocks the slide door 18 and the door drive motor 21 for moving the slide door 18 back and forth are driven by the opening / closing operation of the open / close switch 31 near the driver seat. It can also be driven in the same manner by the indoor switch 27 installed on the vehicle interior side of the vehicle 18 and the outdoor switch 28 installed on the outer handle 95 of the slide door 18. Hereinafter, only the case where the releaser motor 37 and the door drive motor 21 are driven by the operation of the open / close switch 31 will be described, but the same operation will be performed when the operation by the indoor switch 27 and the outdoor switch 28 is performed.

As shown in FIG. 1, the fully open hook mechanism 23 is arranged in the front lower portion 18b of the slide door 18. The fully open hook mechanism 23 is composed of a latch mechanism generally used for vehicle doors, and is in a state of restraining the fully open striker 14 (locked state) and a state of releasing the restraint of the fully opened striker 14 (unlocked state). It is said that it can be switched. Specifically, in the fully open hook mechanism 23, when the slide door 18 is fully opened by the door drive motor 21, the built-in latch and ratchet restrain the fully open striker 14, thereby bringing the slide door 18 into the fully open position. Hold.

As shown in FIG. 1, the releaser motor 37 is also interlocked with the fully open hook mechanism 23 via the releaser cable 44. When the releaser motor 37 is driven by the closing operation of the open / close switch 31, the driving force thereof is transmitted to the fully open hook mechanism 23 via the releaser cable 44. The driving force of the releaser motor 37 causes the fully open hook mechanism 23 to operate in the released state. When the open / close switch 31 is closed when the slide door 18 is locked by the fully open hook mechanism 23 in the fully open state (when the fully open hook mechanism 23 restrains the fully open striker 14), the releaser motor 37 is driven. By force, the fully open hook mechanism 23 is switched from a state in which the fully open striker 14 is restrained (locked state) to a state in which it is released (unlocked state).
Therefore, in the present embodiment, the releaser motor 37 can perform unlocking when the slide door 18 is locked in the fully closed state and unlocking when the slide door 18 is locked in the fully open state. can.

The front hook mechanism 26 is installed at the front portion of the slide door 18, and can be engaged with the second fully closed striker 15 when the slide door 18 is fully closed. The front hook mechanism 26 has the same configuration as that described in, for example, Japanese Patent Application Laid-Open No. 2017-172306. Normally, the front hook mechanism 26 does not restrain the second fully closed striker 15 when the slide door 18 is fully closed. However, the front hook mechanism 26 restrains the second fully closed striker 15 when a large load acts on the slide door 18 from the vehicle interior side to the vehicle outside when the slide door 18 is fully closed. Keep the sliding door 18 locked.

Further, as shown in FIG. 2, an emergency inner release operation unit 24 is connected to the operation link 38 of the releaser device 36 via a releaser cable 45. When the releaser motor 37 is operated by an external force when the releaser motor 37 is in a non-energized state (non-driving state), the operation link 38 can transmit the external force to the fully closed latch mechanism 35 via the releaser cable 42. Therefore, when the releaser cable 45 is pulled in by the manual operation of the emergency inner release operation unit 24 by the occupant, the operation link 38 rotates in the counterclockwise direction in FIG. 2 around the support shaft 39, and the releaser cable 42 The fully closed latch mechanism 35 can be operated in the released state (unlocked state) via the above.
The emergency inner release operation unit 24 is an operation unit for manually unlocking the slide door 18 from the vehicle interior side when the releaser motor 37 cannot unlock the slide door 18 due to a failure of the power supply system or the like.

FIG. 3 is a perspective view of the installation portion of the emergency inner release operation portion 24 at the rear of the slide door 18 as viewed from the vehicle interior 47 side.
The emergency inner release operation unit 24 is installed on the vertical wall portion 48a on the rear side of the window frame 48 of the slide door 18. More specifically, the emergency inner release operation unit 24 is attached to a door trim 49 (interior material) having a narrow front-rear width, which is attached to the passenger compartment 47 side of the vertical wall portion 48a on the rear side of the window frame 48. .. The emergency inner release operation unit 24 is arranged at a height position that can be easily visually recognized by an occupant seated on the seat in the passenger compartment 47.
The door trim 49 of the vertical wall portion 48a is formed with a substantially rectangular opening 50 that is long in the vertical direction. The emergency inner release operation unit 24 has an operation lever 70 described in detail later, and a part of the operation lever 70 is arranged in the opening 50.

Further, as shown in FIG. 2, an emergency outer release operation unit 25 is connected to the operation link 38 of the releaser device 36 via a releaser cable 46. When the releaser cable 46 is pulled in by the manual operation of the emergency outer release operation unit 25, the operation link 38 rotates counterclockwise in FIG. 2 around the support shaft 39 and is fully closed via the releaser cable 42. The latch mechanism 35 can be operated in the released state (unlocked state).
The emergency outer release operation unit 25 is an operation unit for manually unlocking the slide door 18 from the outside of the vehicle interior when the releaser motor 37 cannot unlock the slide door 18 due to a failure of the power supply system or the like.

Reference numeral 19 in FIG. 4 is a front door, and reference numeral 63 is a center pillar. The front door 19 is arranged on the front side of the vehicle body of the slide door 18, and the front end portion is rotatably attached to the front pillar (not shown) of the vehicle body 11 by a hinge. The center pillar 63 is arranged at the leading edge of the door opening 12 on the side of the vehicle body that is opened and closed by the slide door 18.

The emergency outer release operation unit 25 is installed at a position closer to the front inside the slide door 18. A front wall 18d facing the rear surface 19a of the front door 19 is provided at the front end of the sliding door 18. At the end of the front wall 18d on the outer side in the vehicle width direction, an inclined wall 18e that gently inclines outward in the vehicle width direction toward the front side of the vehicle is continuously provided. A space 65 is secured between the inclined wall 18e and the vehicle outer surface of the center pillar 63. A substantially elliptical opening 56 is formed in the inclined wall 18e.

The emergency outer release operation unit 25 has an annular retracting operation unit 58, and the retracting operation unit 58 is arranged at a position facing the opening 56 inside the slide door 18. A cap 61 is detachably attached to the opening 56. During normal use of the slide door 18, the opening 56 is covered with a cap 61, and the pull-in operation portion 58 of the emergency outer release operation portion 25 is hidden from the outside by the cap 61. The cap 61 is removed from the opening 56 in an emergency when the slide door 18 cannot be unlocked by the releaser motor 37. The pull-in operation unit 58 of the emergency outer release operation unit 25 can be operated from the outside.

The holder 71 is surrounded by a base wall 71a, a switch support wall 71b, side walls 71c, 71d, and a cable support wall 71e, and has a recess 72 that opens to the front side.

Support holes 73 are provided on the left and right side walls 71c and 71d of the holder 71, and support pins 74 which are rotation shafts are supported by the support holes 73 of the left and right side walls 71c and 71d. The support hole 73 is provided closer to the upper side than the central portion in the vertical direction of the holder 71. An operation lever 70 is arranged in the recess 72 of the holder 71, and the upper portion of the operation lever 70 is rotatably supported by the support pins 74 on the left and right side walls 71c and 71d.

The operation lever 70 includes an operation block 75 whose direction (vertical direction) intersects with the support pin 74 (rotating shaft) is long, a cable connecting block 76 integrally assembled on the back side of the operation block 75, and an operation block 75. It is provided with a plate-shaped regulating lever 77 arranged between the cable connecting blocks 76. In this embodiment, the operation block 75 and the cable connecting block 76 constitute the lever main body 66.

The operation block 75 is arranged in the opening 50 of the door trim 49, and has a flat design surface 75a-1 exposed to the vehicle interior side through the opening 50. The operation block 75 has a rectangular plate-shaped portion 75a having a design surface 75a-1 and a pair of side wall portions 75b, 75c protruding from both end portions in the width direction of the plate-shaped portion 75a in the back surface direction. ing. The side wall portions 75b and 75c are provided at positions biased upward from the central portion in the longitudinal direction (vertical direction) of the plate-shaped portion 75a. A pin hole 67 into which the support pin 74 is inserted so as to be relatively rotatable is formed in the upper region of each side wall portion 75b, 75c, and the lower edge portion of each side wall portion 75b, 75c is upward from the lower end. A substantially rectangular notch groove 68 extending is formed. The pin hole 67 is arranged in a region closer to the center than the upper end portion in the longitudinal direction of the design surface 75a-1. Therefore, the rotation fulcrum of the operation block 75 by the support pin 74 is set at a position downwardly separated from the upper end portion of the design surface 75a-1 in the longitudinal direction.
The design surface 75a-1 of the plate-shaped portion 75a is set so as to be substantially flush with the vehicle interior side surface of the door trim 49 inside the opening 50 when the operating lever 70 is in the initial position. Further, it is desirable that the plate-shaped portion 75a has the same color as the door trim 49 and is made of the same material.

The cable connecting block 76 is a block that is long in the vertical direction and shorter in the vertical direction than the operation block 75, and a pin hole in which the support pin 74, which is a rotation axis, is inserted so as to be relatively rotatable in the vicinity of the upper end portion. 52 is formed. The cable connecting block 76 is arranged between the left and right side walls 71c and 71d of the operation block 75, and is rotatably supported by the support pin 74 together with the operation block 75.

A cable locking portion 53 to which the end portion of the inner cable 45i of the releaser cable 45 is connected is formed in the vicinity of the lower end portion of the cable connecting block 76. The releaser cable 45 includes an inner cable 45i whose both ends are connected to the cable connecting block 76 and the operation link 38 of the releaser device 36, and an outer tube 45o that slidably covers the outside of the inner cable 45i. ing. Fitting walls 69 fitted in the notched grooves 68 of the side wall portions 75b and 75c of the operation block 75 are provided at both ends of the cable connecting block 76 in the width direction.

Further, between the back surface of the plate-shaped portion 75a of the operation block 75 and the front surface of the cable connecting block 76, a plate-shaped regulating lever 77 having a longitudinal direction in the vertical direction is arranged. The vertical length of the regulation lever 77 is set to be longer than the vertical length of the operation block 75. As shown in FIGS. 10 and 11, guide claws 78 are provided so as to project from the side wall portions 75b and 75c of the operation block 75. The regulation lever 77 is held by the back surface of the plate-shaped portion 75a and the guide claw 78 so as to be slidable (advance and retreat) in the vertical direction.

In the regulating lever 77, the intermediate region in the vertical direction is formed to have a constant thickness, and the upper region is formed to be thicker than the intermediate region. The side edge portion of the intermediate region is slidably guided by the guide claw 78. The surface side of the regulation lever 77 is formed flat so that the regulation lever 77 can be smoothly slid when the regulation lever 77 is slid in the vertical direction. As shown in FIG. 9, the thick upper region has the front surface side abutting against the back surface of the door trim 49 when the operating lever 70 is in the initial position. The upper region of the regulating lever 77 constitutes a regulating portion 77a that abuts on the back surface of the door trim 49 and aligns the design surface 75a-1 with the vehicle interior side surface of the door trim 49.

A torsion coil spring 79 that urges the operating lever 70 to rotate in the initial position direction with respect to the holder 71 is mounted in the peripheral region of the support pin 74. Therefore, the operating lever 70 is in an initial position where the design surface 75a-1 is aligned with the vehicle interior side surface of the door trim 49 when the regulating lever 77 comes into contact with the back surface of the door trim 49 under the urging force of the torsion coil spring 79. It is maintained in a state.

Further, a finger hook portion 77b protruding toward the back surface is provided at the lower end of the regulation lever 77. The finger hook portion 77b is used when the occupant hooks his / her finger and slides the regulation lever 77 up / down.

Further, on the surface of the base wall 71a of the holder 71, at a position above the rotation center (support pin 74) of the operation lever 70, the upper edge portion of the regulation lever 77 during the rotation operation of the operation lever 70 The first protrusion 96 and the second protrusion 97 that regulate the rotation of the operating lever 70 are projected so as to be in contact with the (regulating portion 77a). The first protrusion 96 is projected in the vicinity of the switch support wall 71b of the holder 71, and the second protrusion 97 is projected at a position separated from the lower side of the first protrusion 96. The regulation lever 77 can be retracted to a position where it does not come into contact with the first protrusion 96 when the operation lever 70 rotates.

12 and 13 are cross-sectional views similar to those in FIG. 9, showing the operating state of the emergency inner release operation unit 24.
The first protrusion 96 is shown in FIG. 12 when the regulation lever 77 is advanced (sliding upward) and the lever body 66 is displaced from the initial position around the support pin 74 by a predetermined angle. As such, it comes into contact with the upper edge portion (regulating portion 77a) of the regulating lever 77. As a result, the rotation operation (first operation) of the first stage of the lever main body 66 is restricted. The first protrusion 96 is provided so as to project on the rotation trajectory of the upper edge portion of the regulation lever 77 when the regulation lever 77 is in the forward state. In the present embodiment, the first protrusion 96 constitutes a stopper portion that regulates the rotation of the lever main body portion 66 at the terminal position of the first operation.

When the lever main body 66 is further rotated from the state where the rotation of the lever main body 66 is restricted by the first protrusion 96, the occupant puts his / her finger on the finger hook portion 77b at the lower end of the regulation lever 77 and moves the lever main body 66 toward the front. Pull and slide the regulation lever 77 downward. As a result, the upper edge portion of the regulation lever 77 retracts downward, and the regulation lever 77 does not come into contact with the first protrusion 96 (see the arrow and the virtual line in FIG. 12). As a result, as shown in FIG. 13, the lever main body 66 can be further rotated. When the lever main body 66 is further rotated by a predetermined angle by the operation of the occupant from this state, the upper edge portion of the regulation lever 77 comes into contact with the second protrusion 97, whereby the rotation operation of the lever main body 66 is restricted.

When the lever main body 66 rotates beyond the restricted position by the first protrusion 96, the releaser cable 45 (inner cable 45i) connected to the lower end of the cable connecting block 76 is pulled in, and as a result, the operation link 38 is pulled. It rotates to release the engaged state between the ratchet and the latch, and the fully closed latch mechanism 35 is released (unlocked). Therefore, in the emergency inner release operation unit 24 of the present embodiment, the lock release operation (second) of the fully closed latch mechanism 35 in the rear stage by the operation lever 70 is performed only after the first operation in the front stage is performed on the operation lever 70. Operation) is allowed. In the present embodiment, the lever body 66 rotatably supported by the holder 71, the regulation lever 77 rotatably held by the lever body 66, and the lever body in contact with the upper edge of the regulation lever 77. The first protrusion 96 that regulates the rotation of the portion 66 constitutes the multi-stage operation mechanism 100 in the emergency inner release operation portion 24.

Further, a detection switch 80 for detecting that the operation lever 70 has been rotated (first operated) from the initial position is attached to the switch support wall 71b above the holder 71. The detection switch 80 has, for example, a push-in type contact button 80a and a movable piece 80b that is pressed against the upper edge of the regulation lever 77 in the forward state to push the contact button 80a during the first operation of the operation lever 70. It may be configured.

The detection switch 80 is connected to a drive circuit (not shown) for operating the door drive motor 21 of the slide door 18 and an alarm device (not shown) that emits a warning sound such as a buzzer. When the detection switch 80 detects that the operation lever 70 has been first operated, the operation of the door drive motor 21 is stopped and the warning device emits a warning sound.

Here, an example in which the detection switch 80 for detecting the first operation when the contact button 80a is pushed is installed on the upper side of the holder 71 has been described, but as in the modified example shown in FIG. 14, the contact button A detection switch 80A that detects the first operation when the pushing of the 80Aa is released may be installed on the lower side of the holder 71. In the case of this modification, when the operation lever 70 is in the initial position, the back surface of the lower edge of the operation lever 70 pushes down the contact button 80Aa of the detection switch 80A. When the operation lever 70 is rotated from this state, the contact button 80Aa is raised, and as a result, it is detected that the operation lever 70 has been operated.

A pair of cable support walls 71e at the lower end of the holder 71 are vertically separated from each other on the base wall 71a. As shown in FIGS. 7 and 8, each cable support wall 71e is formed with a groove-shaped tube fixing portion 98 that opens toward one side in the width direction. The end of the outer tube 45o of the releaser cable 45 is fitted to each tube fixing portion 98 from the opening 98a side. The opening 98a of each tube fixing portion 98 into which the outer tube 45o is fitted is closed by the wall 49a of the door trim 49 shown in FIG. 6 in a state where the holder 71 is attached to the back surface of the door trim 49.
The wall 49a of the door trim 49 is a wall bent outward from the trim main wall 49b (the wall on which the opening 50 is formed) facing the inside of the vehicle interior 47.

Here, the cable locking portion 53 (connecting portion with the releaser cable 45) at the lower end of the cable connecting block 76 is lowered by a predetermined distance from the arrangement position of the support pin 74 (rotating shaft) in the longitudinal direction of the lever main body portion 66. It is located at a distance from the cable. Further, the linking mechanism between the lever main body 66 and the operation link 38 (unlocking portion) by the releaser cable 45 is until the lever main body 66 is rotated beyond the first protrusion 96 (during the first operation). Has a play of the inner cable 45i that does not transmit the operating force due to the pulling of the inner cable 45i to the operation link 38 (unlocking portion). Therefore, as shown in FIG. 12, even if the lever main body 66 is rotated, the fully closed latch mechanism 35 is opened in the rotation range in which the rotation of the lever main body 66 is restricted by the first protrusion 96. It will not be in a state (unlocked).

Further, as shown in FIGS. 8 and 11, the holder 71 is fixed to the back surface of the door trim 49 on one side wall 71c of the holder 71 (the side wall located on the side opposite to the opened side of the tube fixing portion 98). A fixed wall 54 is provided so as to project outward in the width direction. The fixing wall 54 is fixed to the boss portion 55 projecting from the back surface of the trim main wall 49b of the door trim 49 by a screw 57.

As described above, the slide door device of the present embodiment includes a multi-stage operation mechanism 100 that allows the rear-stage unlocking operation only after the emergency inner release operation unit 24 performs the first operation of the front-stage. Therefore, even if the emergency inner release operation unit 24 is accidentally operated (the first operation is performed) by an occupant in the vehicle interior, it is possible to prevent the fully closed latch mechanism 35 from being suddenly released. Can be done. Therefore, when the slide door device of the present embodiment is adopted, it is possible to prevent the door lock release due to an erroneous operation of the emergency inner release operation unit 24, and the emergency inner release operation unit 24 is covered with a lid member or the like. Therefore, in an emergency, the emergency inner release operation unit 24 can be quickly accessed from the vehicle interior.

Further, the slide door device of the present embodiment is configured to stop the operation of the door drive motor 21 when the first operation of the previous stage is performed on the emergency inner release operation unit 24. Therefore, even if the door drive motor 21 is in the operating state when the occupant mistakenly first operates the emergency inner release operation unit 24, the slide door 18 is opened by the door drive motor 21. It can be surely prevented from being damaged.

Further, the slide door device of the present embodiment is configured to operate the alarm device when the first operation of the previous stage is performed on the emergency inner release operation unit 24. Therefore, when the occupant mistakenly operates the emergency inner release operation unit 24 for the first time, the alarm device can reliably notify that the operation is erroneous. Therefore, it is possible to prevent the fully closed latch mechanism 35 from being released (unlocked) due to an erroneous operation of the emergency inner release operation unit 24 by the occupant.

In particular, in the present embodiment, since the detection switch 80 (80A) for detecting that the first operation has been performed is provided on the emergency inner release operation unit 24, the first operation is performed by the occupant. This can be instantaneously detected by the detection switch 80 (80A), and the operation of the door drive motor 21 can be stopped or the warning device can be quickly activated.

Further, in the slide door device of the present embodiment, the operation lever 70 of the emergency inner release operation unit 24 is arranged in the opening 50 of the door trim 49, and the operation lever 70 is exposed to the vehicle interior side through the opening 50. It is equipped with 75a-1. The operating lever 70 is further provided with a regulating portion 77a that abuts on the back surface of the door trim 49 when the operating lever 70 is in the initial position to align the design surface 75a-1 with the vehicle interior side surface of the door trim 49. Therefore, when the operating lever 70 is in the initial position, the design surface 75a-1 of the operating lever 70 and the side surface of the vehicle interior of the door trim 49 can be aligned to improve the appearance from the vehicle interior side. Further, with this configuration, the first operation of the emergency inner release operation unit 24 can be easily performed by simply touching and pushing the design surface 75a-1 of the operation lever 70 in the opening 50. Therefore, when this configuration is adopted, the access to the operation lever 70 from the vehicle interior becomes good.

In the slide door device of the present embodiment, the emergency inner release operation unit 24 has a holder 71 and an operation lever 70, and the operation lever 70 has a lever body unit 66 rotatably supported by the holder 71 and a lever. It is provided with a regulation lever 77, which is held in the main body 66 so as to be able to move forward and backward. Then, when the holder 71 is rotated from the initial position of the lever main body 66, the holder 71 comes into contact with the restricting lever 77 in the forward state to restrict the rotation of the lever main body 66 at the end position of the first operation. It is provided with a protrusion 96 (stopper portion). The emergency inner release operation unit 24 further rotates the lever body unit 66 for the lock release operation by retracting the regulation lever 77 that abuts on the first protrusion 96 from the first protrusion 96 after the first operation. Is possible. Therefore, according to this configuration, the multi-stage operation mechanism 100 provided in the emergency inner release operation unit 24 can obtain a multi-stage operation that does not cause inadvertent unlocking.

Further, the emergency inner release operation unit 24 used in the slide door device of the present embodiment has a first protrusion 96 (stopper portion) provided on the holder 71 that rotatably holds the operation lever 70. It is possible to accurately set the rotation restriction position of the operation lever 70 by one protrusion 96. In the case of this configuration, since the operation lever 70 can be attached to the door trim 49 of the slide door 18 as an assembly in a state where the operation lever 70 is assembled to the holder 71, the assembling property to the slide door 18 is improved.

Further, in the slide door device of the present embodiment, the linkage mechanism by the releaser cable 45 of the emergency inner release operation unit 24 is operated for unlocking until the lever main body portion 66 is rotated beyond the first protrusion 96. It has a play that does not transmit the operating force to the link 38. Therefore, the fully closed latch mechanism 35 is not released (unlocked) until the lever main body 66 is rotated beyond the first protrusion 96. Therefore, when this configuration is adopted, it is possible to reliably prevent the fully closed latch mechanism 35 from being released (unlocked) at the stage of the first operation of the operating lever 70.

Further, in the emergency inner release operation unit 24 used in the slide door device of the present embodiment, the support pin 74 (rotating shaft) of the operation lever 70 has a support pin 74 (rotating shaft) of the lever body portion 66 more than the upper end portion of the design surface 75a-1. It is located in the area near the center. Therefore, the occupant can easily rotate the lever main body 66 by pushing the upper end of the lever main body 66 into the opening 50 from the passenger compartment side. Further, after that, the lower end portion of the lever main body portion 66 can be pulled toward the passenger compartment side as needed. Therefore, when this configuration is adopted, it is not necessary to provide the lever main body 66 with a grip portion protruding toward the vehicle interior side, so that the appearance of the lever main body 66 from the vehicle interior side can be improved.

In the emergency inner release operation unit 24 used in the slide door device of the present embodiment, the holder 71 for rotatably holding the operation lever 70 is fixed to the boss portion 55 projecting from the back surface of the door trim 49 by a screw 57. ing. Therefore, by adopting this configuration, the operation lever 70 can be easily installed on the door trim 49.

Further, in the emergency inner release operation unit 24 of the present embodiment, the operation block 75 rotatably held by the holder 71 includes a lever main body unit 66 and a cable connection block 76, and the operation block 75 has a design surface. It has a plate-shaped portion 75a having 75a-1 and a pair of side wall portions 75b and 75c protruding from the widthwise end portion of the plate-shaped portion 75a toward the back surface direction. A cable connecting block 76 is integrally assembled to the side wall portions 75b and 75c, and the side wall portions 75b and 75c are rotatably held by the holder 71 together with the cable connecting block 76. Therefore, when this configuration is adopted, the rigidity of the lever main body 66 as a whole is increased. Therefore, the releaser cable 45 can be smoothly pulled in by the rotation operation of the lever main body 66.

Further, in the emergency inner release operation unit 24 of the present embodiment, a concave groove-shaped tube fixing portion 98 for fixing the outer tube 45o of the releaser cable 45 is provided in the holder 71, and the opening 98a of the tube fixing portion 98 is provided. It is blocked by the wall 49a of the door trim 49. Therefore, when the holder 71 is fixed to the door trim 49, the removal of the outer tube 45o from the tube fixing portion 98 is restricted by the wall 49a of the door trim 49. Therefore, when this configuration is adopted, the outer tube 45o can be stably attached to the holder 71, and the outer tube 45o can be easily assembled to the holder 71.

Subsequently, other embodiments shown in FIGS. 15 and 16 will be described.
FIG. 15 is a schematic side view of the fully closed latch unit 122 of another embodiment, and FIG. 16 is an enlarged view of a part of FIG. The slide door device of this embodiment has the same configuration as that of the above embodiment except for the fully closed latch unit 122.
The fully closed latch unit 122 is arranged at the rear of the slide door and includes a fully closed latch mechanism 35 (door lock mechanism), a releaser device 136, and a lock lever 102 of the child lock device 101. The child lock device 101 has the same configuration as that generally used in a vehicle, and is a slide door when the lock lever 102 is rotated from the initial position (operation prohibition release position) to the lock position (operation prohibition position). The opening operation from the passenger compartment side is prohibited. In FIG. 15, the lock lever 102 is in the initial position.

The releaser device 136 includes a releaser motor 37, an operation link 138 rotatably supported by a support shaft 39 of the support base, a first sublink 104 rotatably supported by the support shaft 103 of the support base, and a first sublink 104. A second sublink 105 is provided.

The releaser motor 37 and the operation link 138 are interlocked with each other via the releaser cable 41. Further, the fully closed latch mechanism 35 and the operation link 138 are interlocked with each other via a releaser cable 42. When the operation link 138 is rotated in one direction by receiving the driving force of the releaser motor 37, the operation force is transmitted to the fully closed latch mechanism 35 via the releaser cable 42. The fully closed latch mechanism 35 is thereby unlocked. Further, the operation link 138 is connected to a releaser cable 46 whose one end is connected to an emergency outer release operation unit (not shown) and another releaser cable 44 whose one end is connected to a fully open hook mechanism (not shown). ..

The first sub-link 104 and the second sub-link 105 are rotatably supported by the same support shaft 103, and are integrally rotatably connected to each other by a connecting pin 106. The first sublink 104 is interlocked with the operation link 138 via the interlocking cable 107. However, the connecting portion between the first sublink 104 and the operation link 138 allows the transmission of the operating force from the first sublink 104 to the operating link 138, and the reverse operation from the operating link 138 to the first sublink 104. The structure does not allow the transmission of force.

Further, the second sub-link 105 is interlocked with an emergency inner release operation unit (emergency lock release operation unit) (not shown) via a releaser cable 44. Therefore, when the first sub-link 104 and the second sub-link 105 are integrally rotatably connected by the connecting pin 106, when the releaser cable 44 is pulled in by the emergency inner release operation unit, the first and first sublinks are first. 2 The operation link 138 is rotated in one direction via the sublinks 104 and 105 and the interlocking cable 107. As a result, the operating force of the operation link 138 is transmitted to the fully closed latch mechanism 35 via the releaser cable 42, and the fully closed latch mechanism 35 is unlocked.

Further, between the first sublink 104 and the second sublink 105, a cutoff mechanism 108 is provided to cut off the operation transmission (transmission of the rotational operation force) from the second sublink 105 to the first sublink 104. ing. The blocking mechanism 108 includes a holding hole 109 and an escape hole 110 formed in the first sublink 104, a slide hole 111 formed in the second sublink 105, and a first sublink 104 and a second sublink 105. It includes a connecting pin 106 that is integrally rotatably connected, and a holding hole 112 formed in the lock lever 102 of the child lock device 101.

The escape hole 110 of the first sublink 104 is formed in an arc shape centered on the support shaft 103, and the holding hole 109 of the first sublink 104 is continuously located at a position closer to the support shaft 103 of the escape hole 110. It is formed. The escape hole 110 and the holding hole 109 are continuously formed. Inside these continuous holes, connecting pins 106 are movably inserted. The slide hole 111 of the second sublink 105 is an elongated hole extending in the radial direction about the support shaft 103, and a connecting pin 106 is movably inserted inside the slide hole 111.

As shown in FIGS. 15 and 16, when the connecting pin 106 is engaged across the holding hole 109 and the slide hole 111, the first sublink 104 and the second sublink 105 centered on the support shaft 103. The relative rotation of the is regulated by the connecting pin 106. Therefore, in this state, the rotational operation force can be transmitted from the second sublink 105 to the first sublink 104.

Further, when the connecting pin 106 is displaced in the direction away from the support shaft 103 from this state, the connecting pin 106 straddles the escape hole 110 and the slide hole 111 as shown by the virtual line in FIG. In this state, when a rotation operation force is applied to the second sublink 105, the connecting pin 106 that rotates integrally with the second sublink 105 is displaced in the escape hole 110. Therefore, in this state, it becomes impossible to transmit the rotational operation force from the second sublink 105 to the first sublink 104.

On the other hand, the holding hole 112 of the child lock device 101 is formed in the shape of a long hole curved in the lock lever 102. The lock lever 102 is rotatably displaced between the initial position (operation prohibition release position) and the lock position (operation prohibition position) about the support shaft 113. A connecting pin 106 is movably inserted into the holding hole 112.

When the lock lever 102 is in the initial position (operation prohibition release position), the connecting pin 106 is held in the inner position close to the support shaft 103 by the holding hole 112 of the lock lever 102. At this time, the connecting pin 106 is engaged with the slide hole 111 of the second sublink 105 across the holding hole 109 of the first sublink 104. Therefore, the first sublink 104 and the second sublink 105 are integrally rotatable about the support shaft 103. Therefore, when the unlocking operation force is input to the second sublink 105 from the emergency inner release operation unit, the operation force is transmitted to the fully closed latch mechanism 35 via the first sublink 104 and the operation link 138. Will be done.

Further, when the lock lever 102 is rotated from the initial position (operation prohibition release position) to the lock position (operation prohibition position), the connecting pin 106 is separated from the support shaft 103 due to the rotational displacement of the holding hole 112. Displace towards position. When the lock lever 102 is displaced to the locked position (operation prohibited position) in this way, the connecting pin 106 is displaced into the escape hole 110 of the first sublink 104, and the second sublink 105 through the connecting pin 106 is displaced to the first sublink. The transmission of the operating force to the 104 is cut off. Therefore, even if the emergency inner release operation unit is operated, the operating force is not transmitted to the fully closed latch mechanism 35.

The sliding door device of the present embodiment can obtain the same basic effects as those of the above-described embodiment, and can also obtain the following further effects.
The slide door device of the present embodiment is provided with a cutoff mechanism 108 that blocks the operation transmission from the emergency inner release operation unit to the operation link 138 when the child lock device 101 is in the operation prohibited state. Therefore, even if a child in the vehicle interior mischiefs and should operate the emergency inner release operation unit (emergency lock release operation unit), the fully closed latch mechanism 35 is released (unlocked). Can be prevented.

The present invention is not limited to the above embodiment, and various design changes can be made without departing from the gist thereof.
