The present invention relates to an operating lever device for a vehicle door.
The present application claims priority based on Japanese Patent Application No. 2018-195301 filed on October 16, 2018, the contents of which are incorporated herein by reference.

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

Further, this type of sliding door device is provided with an operation lever device for manually unlocking the door lock mechanism in an emergency in consideration of a situation in which the actuator cannot operate due to a failure of the power supply system or the like (for example, See Patent Document 1).

In the slide door device described in Patent Document 1, the operation lever of the operation lever device is arranged inside the opening of the door trim, and the opening is normally covered with the lid member. This prevents easy access to the operation lever (erroneous operation of the operation lever) during normal times.

Japanese Patent Laid-Open No. 2001-98819

In the slide door device described in Patent Document 1, the vehicle operation side of the emergency operation lever is hidden by a removable lid member. Therefore, it is possible to prevent the operation lever from being erroneously operated in a normal time, but it is difficult to quickly access the operation lever in an emergency.

As a countermeasure against this, it is conceivable that the operating lever is exposed to the passenger compartment side without being covered with a lid member or the like, and the operating lever is provided with a lock lever. However, in the case of this countermeasure, the device width including the operation lever and the lock lever is widened, and the lock mechanism interlocking with the lock lever occupies the depth direction.

⑦ It is desirable that the operating lever device for vehicle doors does not occupy a lot of space on the cabin side of the door. In particular, when the operation lever device is installed in a portion where the width of the door pillar or the like is narrow and it is difficult to secure a sufficient depth, an operation lever device that occupies a small width and does not occupy a large space in the depth direction is desired. Be done.

However, in the case of an operation lever device with a lock lever attached to the operation lever as in the above measures, it is difficult to apply it to a part where the width of the door pillar is narrow and it is difficult to secure a sufficient depth.

The aspect of the present invention provides an operating lever device for a vehicle door, which has a simple configuration that occupies a narrow width and does not occupy a large space in the depth direction and can prevent erroneous operation of the operating lever.

An operation lever that operates an operation target by a rotation operation, the operation lever being rotated from the passenger compartment side, and having a longitudinal direction in a direction intersecting with the rotation axis, and the operation block. For integrally operating the operation target on the other end side in the longitudinal direction while being integrally assembled to the back side of the one side, one end side in the longitudinal direction intersecting the rotation axis is rotatably supported by the fixing portion. The operation cable is connected to the cable connection block, between the operation block and the cable connection block, a restriction lever disposed so as to be movable back and forth substantially along the longitudinal direction, the fixing portion, When the working lever is rotated by the predetermined angle, it is provided with a stopper portion that comes into contact with the regulation lever in the forward state to regulate the rotation of the operation lever by the predetermined angle or more. It can be moved backward to a position where it does not come into contact with the stopper portion when it is rotated.

The operation lever has a cable connecting block integrally assembled on the back side of the operation block, and a restriction lever that can come into contact with the stopper is held between the operation block and the cable connecting block so that it can move back and forth. Therefore, by keeping the regulation lever in the forward state, it is possible to regulate the rotation of the operation lever beyond the predetermined angle and substantially lock the operation of the operation target (prohibit the operation). Further, by retreating the restriction lever, it is possible to substantially unlock the operation of the operation target. Therefore, in the vehicle door operation lever device according to the present invention, the operation target cannot be operated simply by rotating the operation lever, so that the operation lever can be prevented from being erroneously operated.

With a design surface exposed to the room side, the restriction lever is configured to contact the back surface of the door trim when the operation lever is in the initial position to align the design surface with the vehicle compartment side surface of the door trim. It may be.
In this case, since the restriction lever comes into contact with the back surface of the door trim, the design surface of the operation block and the vehicle interior side surface of the door trim are aligned, so that the appearance from the vehicle interior side becomes good. Further, since the operation lever can be operated by touching the design surface in the opening portion of the door trim, the access to the operation lever from the vehicle interior becomes good.

(5) In the aspect of any one of (1) to (4) above, in the linkage mechanism between the cable connecting block and the operation target by the operation cable, the operation lever is rotated beyond the predetermined angle. It may be configured to have a play that does not transmit an operation force to the operation target until it is operated.
In this case, since the linkage mechanism has a play, the operation target is not operated until the operation lever is rotated beyond the predetermined angle. Therefore, even if the operation lever is erroneously rotated, the operation target can be prevented from being inadvertently operated.

(6) In the above aspect (4), the rotation shaft of the operation lever may be arranged in a region closer to the center of the operation lever than the end portion in the longitudinal direction of the design surface.
In this case, an occupant can easily rotate the operation lever by pushing one end side in the longitudinal direction of the design surface of the operation lever from the passenger compartment side into the opening. Further, at this time, if necessary, the other end side in the longitudinal direction of the operation lever can be pulled to the passenger compartment side. When this configuration is adopted, it is not necessary to provide the operating lever with the grip portion projecting toward the vehicle compartment side, so that the appearance of the operating lever from the vehicle compartment side can be improved.

(7) In the aspect of (3) above, the operation lever is arranged in an opening portion provided in a door trim on the vehicle compartment side of the door, and the holder is provided in a boss portion projecting on a back surface of the door trim. It may be screwed.
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.

(8) In the aspect of the above (1), the operation block includes a plate-shaped portion having a design surface exposed to the passenger compartment side, and a side end in a width direction intersecting a longitudinal direction of the plate-shaped portion from a back surface direction. And a pair of side walls, the cable connecting block is integrally assembled to the pair of side walls, and the pair of side walls is rotatably supported by the fixed portion together with one end of the operation block. May be done.
In this case, the cable connection block that is rotatably supported by the fixed portion and operates the operation cable is integrally assembled to the pair of side wall portions of the operation block. Therefore, the rigidity of the entire operation lever can be increased, and the operation cable can be smoothly pulled in by rotating the operation lever.

(9) In the aspect of (4), the holder is provided with a groove fixing tube fixing portion for fixing the outer tube of the operation cable, and the groove fixing opening of the tube fixing portion is formed in the holder. It may be closed by the door trim wall.
In this case, the outer tube of the operation cable is fixed to the groove-shaped tube fixing portion of the holder, and the holder is fixed to the door trim in that state, whereby the outer tube can be prevented from coming off from the tube fixing portion. Therefore, when this configuration is adopted, the outer tube can be stably fixed to the holder and easily assembled.

(10) In the aspect of any one of (1) to (9), the door is a slide door that slides and opens a door opening of a vehicle body, and the operation target locks the slide door in a closed state. It may be a lock release part of the door lock mechanism.
In this case, it is possible to prevent the door lock mechanism of the slide door from being unlocked when the operation lever is erroneously rotated.

According to the aspect of the present invention, the restriction lever arranged between the operation block and the cable connection block is displaced forward, so that the malfunction of the operation target due to the rotation of the operation lever can be prevented. Therefore, according to the aspect of the present invention, the operation of the operation target due to the erroneous operation of the operation lever can be prevented with a simple configuration in which the occupied width is narrow and the space is not largely occupied in the depth direction.

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

FIG. 1 is a conceptual diagram of a vehicle 10 of an embodiment including a slide door 18. In FIG. 1, the left side surface of the vehicle 10 and the internal structure of the left slide door 18 are also shown.
As shown in FIG. 1, a vehicle 10 includes a slide door 18 that opens and closes a door opening 12 of a side portion 11 a of a vehicle body 11, a movement of the slide door 18 in the vehicle front-rear direction, and a slide door 18 in a fully open / fully closed position. A door actuation system 20 for performing locking and unlocking. The slide door 18 and the door operating system 20 constitute the slide door device of this embodiment.

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

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 section 24, an emergency outer release operation section 25, a front hook mechanism 26, and an opening / closing mechanism. A switch 31, an indoor switch 27, and an outdoor switch 28 are provided. In addition, in this embodiment, the emergency inner release operation unit 24 constitutes an operation lever device.

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

FIG. 2 is a conceptual diagram showing the fully closed latch unit 22, the emergency inner release operation part 24, and the emergency outer release operation part 25.
As shown in FIG. 2, the fully closed latch unit 22 is arranged at the rear portion 18 a 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 structure as a latch mechanism generally used for vehicle doors, and has a state (locked state) in which the first fully closed striker 13 (see FIG. 1) is restrained and a first fully closed striker. It is possible to switch to a state in which the constraint of 13 is released (lock release state). Specifically, the fully-closed latch mechanism 35 switches from the half-latch state to the full-latched state in the latter half of the closing operation of the slide door 18 when the door drive motor 21 closes the slide door 18. In the fully latched state, 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 at 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) holding the first fully closed striker 13 to the released state (locked state). It is switched to the release state).
In the present embodiment, the releaser motor 37 constitutes an unlocking actuator.

The releaser device 36 includes a releaser motor 37 and an operation link 38 rotatably supported by a support shaft 39 of a support base. The releaser motor 37 and the operation link 38 are linked via a releaser cable 41 so as to be interlocked. 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 linked via a releaser cable 42 so as to be interlocked.

The releaser motor 37 is driven and operated by the open / close switch 31 (see FIG. 1). The releaser device 36 causes the releaser motor 37 to rotate the operation link 38 in the counterclockwise direction in FIG. 2 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 full-close latch mechanism 35 via the releaser cable 42, and as a result, the full-close latch mechanism 35 moves the first full-close striker. The state of locking 13 (locked state) is switched to the released state (locked state).
In the present embodiment, the operation link 38 constitutes the lock release part of the door lock mechanism.

The releaser motor 37 for unlocking 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 be similarly driven by an indoor switch 27 installed on the vehicle interior side of 18 and an 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 opening / closing switch 31 will be described, but the same operation is performed even when the indoor switch 27 or the outdoor switch 28 is operated.

The fully open hook mechanism 23 is arranged at the lower front portion 18b of the slide door 18 as shown in FIG. The full-open hook mechanism 23 is composed of a latch mechanism generally used in vehicle doors, and has a state in which the full-open striker 14 is restrained (locked state) and a state in which the restraint of the full-open striker 14 is released (unlocked state). It can be switched. Specifically, when the slide door 18 is fully opened by the door drive motor 21, the fully open hook mechanism 23 restrains the fully open striker 14 by a built-in latch and ratchet, thereby moving the sliding door 18 to the fully open position. Hold.

As shown in FIG. 1, the releaser motor 37 is also linked to the fully open hook mechanism 23 via a releaser cable 44 so as to be interlocked. When the releaser motor 37 is driven by the closing operation of the open / close switch 31, the driving force is transmitted to the fully open hook mechanism 23 via the releaser cable 44. The drive force of the releaser motor 37 operates the fully-open hook mechanism 23 in a released state. When the open / close switch 31 is operated to be 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 of the releaser motor 37 is closed. The driving force causes the fully open hook mechanism 23 to switch from the state in which the fully open striker 14 is restrained (locked state) to the 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. it can.

The front hook mechanism 26 is installed in the front part of the slide door 18, and can engage with the second fully closed striker 15 when the slide door 18 is in the fully closed state. The front hook mechanism 26 has the same configuration as that disclosed in, for example, JP-A-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 is applied to the slide door 18 from the vehicle interior side to the vehicle exterior side when the slide door 18 is fully closed. The sliding door 18 is maintained in the locked state.

Further, as shown in FIG. 2, the emergency inner releasing operation part 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 the non-energized state (non-driven 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 occupant's manual operation of the emergency inner release operation part 24, the operation link 38 rotates about the support shaft 39 in the counterclockwise direction in FIG. The fully closed latch mechanism 35 can be operated to the released state (unlocked state) via.
The emergency inner release operation section 24 is an operation section for releasing the lock by manual operation from the passenger compartment side when the lock of the slide door 18 cannot be released by the releaser motor 37 due to a failure of the power supply system or the like. In addition, the emergency inner release operation part 24 constitutes the operation lever device in the present embodiment.

FIG. 3 is a perspective view of the installation part of the emergency inner release operation part 24 (operation lever device) at the rear part of the slide door 18 as viewed from the vehicle compartment 47 side.
The emergency inner releasing 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 releasing operation portion 24 is attached to a door trim 49 having a narrow front-rear width that is attached to the vehicle 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 where an occupant seated on a seat in the vehicle compartment 47 can easily visually recognize it.
