  In the vehicle door lock device described in Patent Document 1 described above, the lock operation unit is an active lever that can be driven to rotate and can be switched between an unlock position and a lock position (in Patent Document 1, a lock lever and a lock lever). And a drive mechanism for driving the active lever.

  Further, in the vehicle door lock device described in Patent Document 1 described above, the engagement protrusion provided on the arm portion of the active lever can slide in the long hole formed in the open link and extending in the link longitudinal direction. The open lever is connected to one end of the open link in the longitudinal direction of the link so as to be able to be pushed and swung. For this reason, when the open lever is operated, the open link moves in the link longitudinal direction. When the active lever is switched between the unlocked position and the locked position by rotation, the open link tilts with the connecting portion with the open lever as a fulcrum as the active lever rotates.

(Problems to be solved by the invention)
By the way, in the vehicle door lock device described in Patent Document 1 described above, it is necessary to form a long hole extending in the longitudinal direction of the link in the open link. Cost may increase. In addition, the open link can be tilted with the connecting portion with the open lever as a fulcrum, and can move in the longitudinal direction of the link at each position of the unlock position and the lock position. It is necessary for the device, and the device becomes large and the vehicle mounting property may be deteriorated.

(Means for solving the problem)
The present invention has been made to solve the above-described problems, and in the vehicle door lock device targeted by the present invention described above, the open link is located at a position where the active link is displaced as the active lever rotates. A biasing member that biases the open link toward the initial position is provided from the initial position to the operating position so as to be rotatable relative to the active lever, and the active lever is in the unlocked position. When the open link is also in the unlocked position, the open link and the open lever can be engaged, and when the active lever is in the locked position, the open link is also in the locked position and the open link is open. It is characterized in that the link and the open lever cannot be engaged.

  In this case, the open lever is driven in accordance with an operation of an inside open lever provided on the inside of the door and an outside door handle provided on the outside of the door. It is also possible that the inside open lever and the outside open lever are arranged coaxially.

(Effects of the invention)
In the vehicle door lock device according to the present invention, the open link is rotatably attached to the active lever, and the open link does not require a long hole (a long hole extending in the link longitudinal direction of the conventional device). It is possible to reduce the part cost by reducing the size of the link. In addition, since a support structure is employed in which the open link is supported and supported by the active lever so as to be relatively rotatable, it can be tilted with a greater degree of freedom compared to a conventional support structure (a rotatable support structure). Compared with the support structure), the support of the open link can be stabilized, and the operation reliability of the open link can be improved.

  In the vehicle door lock device according to the present invention, when the active lever is in the lock position, the open link is also in the lock position, and the open link and the open lever cannot be engaged. The open link in the open lever does not rotate with respect to the active lever when the open lever is opened, and the open link operating range is compared to when the open link in the locked position is activated (in the case of the conventional device). Can be reduced. For this reason, it is possible to reduce the size of the device and to improve the vehicle mountability.

  In the vehicle door lock device according to the present invention, the open lever (inside open lever) driven by the door opening operation of the inside door handle is integrally provided with the pushing portion, and the active lever is locked at the locking position. By providing an engaging part that can be engaged with the moving part and the active lever is pushed toward the unlocked position when engaged, a so-called one-motion or double-pull inside door handle unlocking mechanism is provided. It can be handled without increasing the number of parts.

  In implementing the present invention described above, the open lever includes an inside open lever that is driven in accordance with an operation of the inside door handle provided inside the door, and an outside door handle provided outside the door. When the outside open lever is driven by an operation and the inside open lever and the outside open lever are arranged coaxially, the support shaft of each open lever can be shared. In addition, the number of components of the vehicle door lock device can be reduced, and the vehicle door lock device can be reduced in size and cost.

When operated, (c) When the outside door handle is opened in the locked state, (d) When the inside door handle is double-pull operated in the locked state, (e) When the door is opened, the door is locked. When the door is closed in the state, (f) When the door is opened and locked, and when the door is closed in a state in which the door is maintained, each component operates as follows.

"(A) Operation when opening the inside door handle in the unlocked state"
When the vehicle door locking device 100 is in the unlocked state as shown in FIG. 1, when the inside open lever 21 is actuated in the door opening direction in accordance with the door opening operation of the inside door handle (not shown), FIG. As shown, the open link 23 in the unlocked position is rotated counterclockwise from the initial position (position in FIG. 1) to the operating position in FIG. 4 by the inside open lever 21 and engages with the lift lever 13. . For this reason, the door opening direction operation of the inside open lever 21 is transmitted to the lift lever 13 through the open link 23, the lift lever 13 rotates in the unlatching direction, and the latch mechanism 10 changes from the latched state to the unlatched state. It is possible to open.

"(B) Operation when the outside door handle is opened by unlocking"
Further, when the vehicle door lock device 100 is unlocked as shown in FIG. 1, the outside open lever 22 is actuated in the door opening direction in accordance with the door opening operation of the outside door handle (not shown). As shown in FIG. 5, the open link 23 in the unlocked position is rotated counterclockwise from the initial position (position of FIG. 1) to the operating position of FIG. 13 is engaged. Therefore, the door opening direction operation of the outside open lever 22 is transmitted to the lift lever 13 via the open link 23, the lift lever 13 rotates in the unlatching direction, and the latch mechanism 10 changes from the latched state to the unlatched state. Can be opened.

"(C) Operation when the outside door handle is opened by locking"
Further, when the vehicle door lock device 100 is in the locked state as shown in FIG. 6, when the outside open lever 22 is actuated in the door opening direction in accordance with the door opening operation of the outside door handle (not shown), The outside open lever 22 is swung without engaging with the open link 23 in the locked position. Therefore, the operation of the outside open lever 22 in the door opening direction is not transmitted to the open link 23, the lift lever 13 does not rotate, the latch mechanism 10 is maintained in the latched state, and the door cannot be opened.

“(D) Operation when the inside door handle is double-pull operated in the locked state”
On the other hand, when the vehicle door lock device 100 is in the locked state as shown in FIG. 6, when the inside open lever 21 is operated in the door opening direction in accordance with the door opening operation of the inside door handle (not shown), the lock position is reached. The drive start timing of the active lever 31 toward the unlocked position by the inside open lever 21 (that is, the engagement start timing of the push arm portion 21d with the engagement pin portion 31f) is the opening operation of the inside open lever 21. It is delayed by a predetermined amount compared to the start timing.

  Therefore, at this time, after the inside open lever 21 is opened by a predetermined amount, the inside open lever 21 moves the active lever 31 and the open link 23 at the lock position toward the unlock position, and the open link 23 is moved to the inside. A state in which the operation of the open lever 21 in the door opening direction cannot be transmitted to the lift lever 13 (as shown in FIG. 7, the output arm portion 23 c of the open link 23 is engaged with the push arm portion 21 c of the inside open lever 21. In a so-called panic state), the open link 23 is held by the inside open lever 21.

  For this reason, in this embodiment, the inside door handle (not shown) once opened is once returned and the door is opened again (pull operation twice), thereby eliminating the panic state and opening the door. It is possible. When the inside door handle (not shown) that has been opened once is returned, the inside open lever 21 is returned to the initial position (the position shown in FIGS. 1 and 6) when the inside door handle (not shown) is returned. Along with the movement, the engagement (holding) of the inside open lever 21 and the open link 23 is released.

  Thus, the active lever 31 is rotated to the unlocked position by the spring S3, and the open link 23 is moved to the initial position (one arm portion 24b is engaged with the engaging arm portion 23d of the open link 23) by the spring (biasing member) 24. While engaging with one side of the locking projection 31e of the active lever 31, the other arm portion 24c engages with the engagement arm portion 23d of the open link 23 and the other side of the locking projection 31e of the active lever 31. 1 to the unlocked state shown in FIG.

  For this reason, when the inside door handle (not shown) is opened again, the inside open lever 21 drives the open link 23 in the initial position to the operating position as shown in FIG. Accordingly, the door opening direction operation of the inside open lever 21 is transmitted to the lift lever 13 via the open link 23, the lift lever 13 rotates in the unlatching direction, and the latch mechanism 10 changes from the latched state to the unlatched state, thereby opening the door. It is possible.

"(E) Operation when the door is locked with the door open and the door is closed in that state"
In this embodiment, since the vehicle door lock device 100 is provided with the keyless lock lever 41, the spring 42, the cancel lever 43, etc., for example, a lock knob (not shown) is operated with the door open. When the door is closed in this state as shown in FIG. 6, the latch 11 of the latch mechanism 10 is engaged with a striker (not shown) and temporarily rotated as is well known. After the lift lever 13 of the mechanism 10 temporarily rotates in the unlatching direction, it returns to the original state. Therefore, the cancel lever 43 shown in FIG. 6 is temporarily pushed by the lift lever 13 and rotated by a predetermined amount in the counterclockwise direction, and the keyless lock lever 41 is rotated in the clockwise direction by the engagement pin portion 43b. To push.

  Incidentally, in the locked state shown in FIG. 6, the keyless lock lever 41 is engaged with the protrusion 31 g of the active lever 31, and the active lever 31 can rotate integrally with the keyless lock lever 41 only in the clockwise direction. As a result, when the keyless lock lever 41 is pushed clockwise by the cancel lever 43, the active lever 31 at the lock position moves together with the open link 23 toward the unlock position. Therefore, at this time, the unlocking operation is obtained by closing the door, and the locked state shown in FIG. 6 becomes the unlocked state shown in FIG. 1, and so-called key confinement operation can be prevented.

“(F) Operation when the door is locked with the door open and closed with the door open”
The unlocking operation by the door closing operation of (e) described above is performed by operating the lock knob (not shown) with the door opened to lock the door as shown in FIG. ) Can be canceled by opening the door and closing the door in that state. In this case, the state shown in FIGS. 8 and 9 is obtained, and the active lever 31 and the open link 23 are maintained in the locked position. Therefore, if the outside door handle (not shown) is then returned to the original position, the outside open lever 22, the keyless lock lever 41, the spring 42, etc. return to the state shown in FIG. 6, and the locked state is maintained. Keyless lock is possible. The cancel lever 43 returns to the state shown in FIG. 6 before returning the outside door handle (not shown).

  The state shown in FIG. 8 shows a state when the lock knob (not shown) is operated in the locked state with the door opened, and then the outside door handle (not shown) is opened. At this time, the operation of the outside open lever 22 in the door opening direction causes the pushing arm portion 22d of the outside open lever 22 to engage with the engaging arm portion 41e of the keyless lock lever 41 to push the keyless lock lever. 41 rotates counterclockwise by a predetermined amount against the spring force of the spring 42. Therefore, the engagement pin portion 43 b of the cancel lever 43 is engaged with the upper end portion of the arc-shaped elongated hole extending in the circumferential direction of the support shaft 53 in the cam hole 41 c of the keyless lock lever 41.

  On the other hand, in the state shown in FIG. 9, the door is closed in the state shown in FIG. 8, and the latch 11 of the latch mechanism 10 is engaged with a striker (not shown) and is temporarily rotated as is well known. Thus, the lift lever 13 of the latch mechanism 10 is temporarily rotated in the unlatching direction. At this time, the cancel lever 43 shown in FIG. 8 is temporarily pushed by the lift lever 13. It rotates by a predetermined amount in the counterclockwise direction. By the way, at this time, the engaging pin portion 43b of the cancel lever 43 moves along an arc-shaped elongated hole extending in the circumferential direction of the support shaft 53 in the cam hole 41c of the keyless lock lever 41. The lever 41 is swung without being pushed. Therefore, at this time, the keyless lock lever 41 does not rotate in the clockwise direction, and the active lever 31 and the open link 23 are maintained at the locked position.

  By the way, in the vehicle door lock device 100 of the above-described embodiment, the open link 23 is assembled to the boss portion 31b of the active lever 31 so as to be relatively rotatable, and the open link 23 has a long hole (link length of the conventional device). Therefore, it is possible to reduce the cost of the parts by reducing the size of the open link 23. In addition, since the support structure in which the open link 23 is assembled and supported by the boss portion 31b of the active lever 31 so as to be relatively rotatable is employed, the conventional support structure (comparable to the rotatable support structure) is adopted. The support of the open link 23 can be stabilized and the operation reliability of the open link 23 can be improved as compared with a tiltable support structure having a large degree.

  In the vehicle door lock device 100, when the active lever 31 is in the locked position, the open link 23 is also in the locked position, and the open link 23 and the open levers 21 and 22 cannot be engaged. The open link 23 in the position does not rotate with respect to the active lever 31 when the doors of the open levers 21 and 22 are opened, and the open link 23 in the locked position operates (in the case of the conventional device). Thus, the operating range of the open link 23 can be reduced. For this reason, it is possible to reduce the size of the device and to improve the vehicle mountability.

  Further, in the vehicle door lock device 100, the push arm portion 21d is integrally provided on the inside open lever 21 driven by the door opening operation of the inside door handle (not shown), and the active lever 31 is locked at the locked position. The engagement pin portion 31f that can be engaged with the push arm portion 21d and is pushed toward the unlock position when engaged is integrally provided with an inside door handle such as a so-called double pull. The release mechanism can be used without adding parts.

  Further, in the vehicle door lock device 100, the inside open lever 21 and the outside open lever 22 are arranged coaxially and are rotatably attached to the support shaft 51. For this reason, it is possible to share the support shaft 51 of each open lever 21, 22, the number of components of the vehicle door lock device 100 can be reduced, and the vehicle door lock device 100 can be downsized. It is also possible to reduce costs.

  In the above embodiment, the double pull function (the function of unlocking by the double pull operation of the inside door handle) is implemented and implemented, but the drive toward the unlock position by the inside open lever 21 of the active lever 31 is started. It is also possible to configure and implement a one-motion function (a function of unlocking by a single pull operation of the inside door handle) by making the timing a predetermined amount earlier than in the above embodiment.

  In the above embodiment, the vehicle door lock device 100 is provided with the keyless lock lever 41, the spring 42, the cancel lever 43, and the like. However, in implementing the present invention, the keyless lock lever 41, the spring 42, It is also possible to carry out without the lever 43 and the like.
