  In the vehicle door lock device described in Patent Document 1 described above, when the double lock mechanism is in a double lock unset state and the lock mechanism is permitted to operate, the open link is locked. Then, when the inside open lever is operated in the door opening direction in accordance with the door opening operation of the inside door handle, the so-called one-motion operation (or double pull operation) is obtained by the lock mechanism, and the open link Is switched from the locked position to the unlocked position, and the door can be opened by the door opening operation of the inside door handle. Further, the lock knob is linked to the active lever, and the open link can be switched between the lock position and the unlock position by operating the lock knob.

(Problems to be solved by the invention)
In the vehicle door lock device described in Patent Document 1 described above, the one-motion operation described above is set, and the lock position is set by the door opening direction operation of the inside open lever or the lock knob unlocking operation. A locking lever (a constituent member of a lock mechanism described as a lock operation lever in Patent Document 1) that is rotationally driven from the position to the unlock position, and a latched lever that is assembled to the lever and can be rotationally driven integrally ( The active lever (linked to the open link and unlocked by the lock mechanism) is formed of a linear spring steel material and can be elastically deformed when force is transmitted to the active lever in the lock mechanism. Can be switched to position or lock position) Structure to move to the unlocked position has been adopted.

  For this reason, when the one-motion operation or the lock knob operation described above is performed, the latched lever is elastically deformed and flexed to transmit a force to the active lever, and in response to the door opening operation of the inside door handle or the lock knob operation. There is a possibility that a feeling of delay occurs in the initial stage of the movement of the active lever from the locked position to the unlocked position, thereby impairing the operation feeling. Note that the bending of the latching lever described above can be reduced by changing the shape and material of the latching lever, but in that case, the size and cost of the device are increased. May occur.

  Therefore, the present invention does not impair the operation feeling of the mechanical operation member (the inside door handle or the lock knob) that can move the active lever from the lock position to the unlock position, and even when the panic state occurs. Another object of the present invention is to provide a double lock type vehicle door lock device capable of smoothly switching to an unlocked state.

(Means for solving the problem)
The present invention relates to a latch mechanism that is assembled to a vehicle door and can be held in a state in which the door is closed with respect to the body, and an inside door handle that is rotatably linked to the door and provided on the vehicle interior side of the door. The inside open lever that is driven by the operation, and the inside open lever that is rotatably connected to the door and provided between the inside open lever and the lift lever included in the latch mechanism, and the door opening operation of the inside door handle. An open link that can be switched between an unlock position that transmits the door open direction operation of the inside open lever to the lift lever and a lock position that is not transmitted to the lift lever, and for switching the open link to the unlock position or the lock position. And a double lock set that regulates the operation of this lock mechanism. In the door lock device for a double-lock type vehicle is provided with a double locking mechanism that can be switched to the double-lock unset state that allows the operating condition or the locking mechanism,
The lock mechanism is rotatably linked to the door and can be held in an unlocked position or a locked position, and linked to a door opening direction operation of the inside open lever or a lock knob unlocking operation provided inside the door of the door. An active lever that can be moved from a locked position to an unlocked position, and a predetermined amount of relative rotation with respect to the active lever, and is linked to the open link. A panic lever that can be switched to a locked position, a stopper that is provided on the active lever and restricts rotation in the unlocking direction when the panic lever is at a fixed position, and the panic lever is unlocked toward the fixed position. A biasing member biasing in the direction,
When the open link is switched from the unlock position to the lock position by moving the active lever from the unlock position to the lock position, the panic lever operates integrally with the active lever, and When the open link is switched from the locked position to the unlocked position by moving the active lever from the locked position to the unlocked position, the panic lever is connected to the active lever via the biasing member. Set to work together,
The double lock mechanism is provided with a double lock lever that is rotatably linked to the door and can be switched to an unset position to be in the double lock unset state or a set position to be in the double lock set state,
When the panic lever and the open link are in the locked position and the double lock lever is in the unlocked position, the panic lever and the open link are allowed to move from the locked position to the unlocked position, and The active lever is set to allow movement from the locked position to the unlocked position,
When the panic lever and the open link are in the locked position and the double lock lever is in the set position, the panic lever and the open link are restricted from moving from the locked position to the unlocked position, and the active The lever is set so as to be allowed to move from the locked position to the unlocked position.

  In carrying out the present invention, when the double lock mechanism is in the double lock unset state (when the door lock device is in the lock state), the active lever is operated by the door open direction operation of the inside open lever. It is also possible to engage the inside open lever and move from the locked position to the unlocked position. In this case, when the door lock device is in a locked state, it is possible to set so as to obtain a so-called one-motion or double-pull operation by opening the door of the inside door handle.

(Effects of the invention)
In the double lock type vehicle door lock device according to the present invention, the open link is in the unlock position by the lock mechanism, the lock mechanism is in the unlocked state, and the double lock mechanism is in the double lock unset state. When the inside door handle is opened (when unlocked), the door opening direction operation of the inside open lever accompanying this door opening operation is transmitted to the lift lever of the latch mechanism via the open link in the unlocked position. Thus, the latch mechanism is opened and the door can be opened by the door opening operation of the inside door handle.

  In addition, the general vehicle door lock device also includes an outside open lever that is driven in accordance with the operation of the outside door handle provided outside the door, and is associated with the door opening operation of the outside door handle. Similarly to the door opening direction operation of the inside open lever accompanying the door opening operation of the inside door handle, the open link can be driven by the door opening direction operation of the outside open lever. Therefore, at this time (when unlocked), if the outside door handle is operated to open the door, the door opening direction operation of the outside open lever accompanying this door opening operation is via the open link at the unlock position. Then, the latch mechanism is opened by being transmitted to the lift lever of the latch mechanism, and the door can be opened also by the door opening operation of the outside door handle.

  Also, when the open link is locked by the lock mechanism, the lock mechanism is in the locked state, and the double lock mechanism is in the double lock unset state (when locked) Along with this, if the so-called double pull operation is set, the latch mechanism can be operated by the double pull operation of the inside door handle (the first pull operation and the second pull operation after the inside door handle is returned once). It is possible to open the door by opening the door.

  At this time (when locked), it is activated by the door opening direction operation of the inside open lever accompanying the door opening operation of the inside door handle in the initial and middle stages of the first door opening operation (first pull operation) of the inside door handle. The lever, panic lever, etc. are not switched from the locked position to the unlocked position, and the open link at the locked position is driven. In the latter stage of the first pull operation, the active lever, the panic lever, and the like are switched from the locked position to the unlocked position and the open link is continuously driven by the door opening direction operation of the inside open lever.

  For this reason, in the initial and middle periods of the first pull operation, the movement of the open link is not transmitted to the lift lever of the latch mechanism, the latch mechanism is maintained in the closed state (latched state), and the door cannot be opened. In the latter stage of the first pull operation, the active link, panic lever, etc. are switched from the locked position to the unlocked position, so that the open link is switched from the locked position to the unlocked position. Since the open link is driven by a predetermined amount and is in a so-called panic state, the driving force is not transmitted from the open link to the lift lever of the latch mechanism, the latch mechanism does not open, and the door cannot be opened. .

  In the panic state described above, the active lever is switched and held in the unlock position, but the panic lever rotates relative to the active lever against the urging force of the urging member and moves to the unlock position. It has not been switched. For this reason, the above-described panic state is the direction in which the panic lever is unlocked relative to the active lever by the urging force of the urging member when the open door moves toward the return position once the inside door handle is returned. The panic lever and the open link are switched to the unlocked position.

  Therefore, when the inside door handle is pulled for the second time, the active lever, panic lever, etc. are switched to the unlocked position, and the open link is moved to the unlocked position. Similarly, the door opening direction operation of the inside open lever accompanying the door opening operation of the inside door handle is transmitted to the lift lever of the latch mechanism via the open link in the unlock position, and the latch mechanism opens and the inside door opens. The door can be opened by the second door opening operation of the handle.

  When the open link is locked by the lock mechanism, the lock mechanism is in the locked state, and the double lock mechanism is in the double lock set state (during double lock), the panic lever and open link are In the locked position, the double lock lever is in the set position, the panic lever and the open link are restricted from moving to the unlock position by the double lock lever, and the active lever is moved from the fixed position to the biasing force of the biasing member. Resisting movement (movement in the unlocking direction) is allowed.

  Therefore, at this time (during double locking), in any door opening operation of the inside door handle, in the latter period, the active lever is swung with respect to the panic lever and the open link, and the panic lever in the locked position The open link does not rotate toward the unlock position. Therefore, at this time, the panic lever of the lock mechanism is maintained in the locked state, and the door cannot be opened by the door opening operation of the inside door handle.

  Note that when the outside door handle is opened, the active lever, panic lever, etc. are not switched from the locked position to the unlocked position when the outside door handle is opened. Is maintained in the locked position. For this reason, when the outside door handle is operated to open at the time of locking and double locking as described above, the door opening direction operation of the outside open lever accompanying this door opening operation is transmitted to the open link at the lock position. However, it cannot be transmitted from the open link in the locked position to the lift lever of the latch mechanism. Therefore, at this time, the latch mechanism does not open, and the door cannot be opened by the door opening operation of the outside door handle.

  The above description is a case where a so-called double-pull operation is obtained in accordance with the door opening operation of the inside door handle when the door lock device is locked. It is also possible to set so as to obtain a so-called one-motion operation in accordance with the door opening operation of the door handle. In this case, it is possible to open the door by opening the latch mechanism by a single pull operation (one pull operation) of the inside door handle. In implementing the present invention, the so-called one-motion operation (or double-pull operation) is set so as not to be obtained, and the active lever is moved from the lock position in conjunction with the unlocking operation of the lock knob provided inside the door. It is also possible to implement the configuration so as to be movable to the unlock position.

  By the way, in the door lock device of the present invention, the panic lever is rotatable relative to the double lock lever in a state where the panic lever is connected to the active lever so as to be integrally rotatable by a stopper and a biasing member provided on the active lever. Therefore, when the active lever rotates and moves in the unlocking direction in conjunction with the door opening direction operation of the inside open lever accompanying the door opening operation of the inside door handle or the unlocking operation of the lock knob provided inside the door of the door The lever rotates together with the active lever in the unlocking direction. Therefore, there is no delay in the initial movement of the active lever and panic lever from the locked position to the unlocked position with respect to the door opening operation of the inside door handle or the unlocking operation of the lock knob, and the door opening operation of the inside door handle is not performed. The operation feeling during the unlocking operation of the lock knob or the lock knob is not impaired.

  Further, in the door lock device of the present invention, when the above-described panic state is caused by the door opening operation of the inside door handle in the locked state, as described above, the inside door handle is temporarily returned. The panic lever can be switched to the unlock position, and the above-described panic state can be easily eliminated.

  In carrying out the present invention described above, a locking lever that is rotatably linked to the door and is linked to the active lever, and a position (an unlocked position or a locked position) where the active lever is held. It is also possible to provide position detecting means capable of detection. In this case, the door lock device is attacked from the outside of the vehicle (an illegal act at the time of theft), for example, a locking lever that is linked to the active lever so as to be interlocked (connected to a lock knob that can be attacked from the outside of the vehicle). It is possible to detect the attack from the outside of the vehicle by the position detection means. For this reason, it is possible to detect an attack from the outside of the vehicle to the door lock device by the position detection means described above, and to set an alarm, for example, at the time of the attack. It is possible to improve the property.

  In implementing the above-described present invention, it is desirable that the double lock lever is set to be engageable and disengageable with respect to the panic lever held at the lock position. In this case (that is, when the panic lever that can move only between the unlocked position and the locked position is provided with a part that can be engaged / disengaged with the double lock lever), the open link (unlocked position and locked position) Double-lock lever in a position that can move between the push position engageable with the lift lever and the return position that is separated from the lift lever, and can move over a wider range than the panic lever) Compared to the case where a part that can be engaged and disengaged is provided, the space for moving the part that can be engaged and disengaged with the double lock lever is less, so the door lock device can be downsized. It is.

  In carrying out the present invention described above, a key lever that is rotatably linked to the door and can be mechanically rotated by an operation member such as a key blade is provided, and the key lever is directed from the lock position to the release position. It is also possible to set the double lock lever to move from the set position to the unlock position and to move the active lever from the lock position to the unlock position by being rotated. In this case, for example, the key lever can be rotated from the lock position to the release position by a mechanical rotation operation using an operation member such as a key blade, whereby the double lock lever is unset from the set position. It is possible to move the active lever from the locked position to the unlocked position while moving to the position. Therefore, the door lock device can be released urgently by a mechanical rotation operation using an operation member such as a key blade.

When the position is moved to (position), the driving of the electric motor 46 is stopped, and the display lamp (not shown) is turned off (or turned on).

  Further, the position switch SW is activated when the door lock device in the locked state (the state shown in FIG. 5) or the double locked state (the state shown in FIG. 6) is in the locked position due to an attack from the outside of the vehicle (an illegal act at the time of theft). When the lever 41 and the locking lever 42 are rotated toward the unlock position (see FIG. 7), a warning buzzer (not shown) is set to issue an alarm. That is, in the first embodiment, the position switch SW is set so as to function even during the above-described attack.

  In the first embodiment configured as described above, as shown in FIGS. 1, 2 and 3, the open link 33 is set to the unlock position by the lock mechanism A3, and the lock mechanism A3 is unlocked. And when the inside door handle is opened, when the double lock mechanism A4 is in the double lock unset state (when unlocked), the door opening direction of the inside open lever 32 accompanying this door opening operation The operation is transmitted to the lift lever 23 of the latch mechanism A1 through the open link 33 in the unlock position, the latch mechanism A1 is opened, and the door can be opened by the door opening operation of the inside door handle. .

  At this time (at the time of unlocking), when the outside door handle is operated to open the door, the open link 33 in which the door opening direction operation of the outside open lever 31 accompanying the door opening operation is in the unlocked position is opened. The latch mechanism A1 is opened by being transmitted to the lift lever 23 of the latch mechanism A1, and the door can be opened also by the door opening operation of the outside door handle.

  Further, as shown in FIG. 5, when the open link 33 is in the locked position by the lock mechanism A3, the lock mechanism A3 is in the locked state, and the double lock mechanism A4 is in the double lock unset state ( When the inside door handle is opened, the so-called double pull operation is obtained, and the inside door handle double pull operation (the first pull operation and the second pull after the inside door handle is returned once) By the operation), the latch mechanism A1 can be opened to open the door.

  At this time (at the time of locking), by the door opening direction operation of the inside open lever 32 accompanying the door opening operation of the inside door handle in the initial stage and middle period of the first door opening operation (first pull operation) of the inside door handle, The active lever 41, the panic lever 43, and the like are not switched from the locked position to the unlocked position, and the open link 33 at the locked position is driven (pushed upward). Further, in the latter stage of the first pull operation, the active lever 41, the panic lever 43, and the like are switched from the locked position to the unlocked position by the door opening direction operation of the inside open lever 32, and the open link 33 is continuously driven ( Pushed upward).

  For this reason, in the initial and middle stages of the first pull operation, the movement of the open link 33 is not transmitted to the lift lever 23 of the latch mechanism A1, and the latch mechanism A1 is maintained in the closed state (latched state) to open the door. I can't. In the latter stage of the first pull operation, the active link 41, the panic lever 43, etc. are switched from the locked position to the unlocked position, so that the open link 33 is switched from the locked position to the unlocked position. At this time, the open link 33 is driven by a predetermined amount (pushing upward), and a so-called panic state (a state where the side surface of the push portion 33c of the open link 33 engages the side portion of the lift lever 23). Therefore, the driving force is not transmitted from the open link 33 to the lift lever 23 of the latch mechanism A1, the latch mechanism A1 does not open, and the door cannot be opened.

The active lever 41 is allowed to move against the urging force of the torsion spring 44 (movement in the unlocking direction) from a fixed position (position in FIG. 6).

  Therefore, at this time (during double lock), in any door opening operation of the inside door handle, in the latter period, the active lever 41 is swung with respect to the panic lever 43 and the open link 33 and is in the locked position. The panic lever 43 and the open link 33 are not rotated toward the unlock position. Therefore, at this time, the panic lever 43 of the lock mechanism A3 is maintained in the locked state, and the door cannot be opened by the door opening operation of the inside door handle.

  At the time of locking and double locking described above, no matter how the outside door handle is opened, the active lever 41, the panic lever 43, etc. are not switched from the locked position to the unlocked position. The open link 33 is maintained in the locked position. Therefore, when the outside door handle is operated to open the door at the time of locking and double locking as described above, the door opening direction operation of the outside open lever 31 accompanying the door opening operation is the open link 33 at the lock position. Is not transmitted from the open link 33 in the locked position to the lift lever 23 of the latch mechanism A1. Therefore, at this time, the latch mechanism A1 does not open and the door cannot be opened by the door opening operation of the outside door handle.

  By the way, at the time of locking of the first embodiment, the panic lever 43 is connected to the active lever 41 by the stopper 41b provided on the active lever 41 and the torsion spring 44 so as to be integrally rotatable with the double lock lever 51.
