Definitions

  • the present invention relates to a double-locking door lock apparatus for a vehicle.
  • a door lock apparatus (double-looking door lock apparatus) for a vehicle disclosed in JP3767342B (hereinafter referred to as Reference 1) retains a vehicle door relative to a vehicle body in a closed state.
  • the double-locking door lock apparatus includes a latch mechanism, an inside open lever, an open lever (outside open lever), and an open link.
  • the latch mechanism is attached to the vehicle door together with a housing.
  • the inside open lever rotatably attached to the housing is rotated from an initial position to a rotated position by a door opening operation of an inner side door handle arranged at an inner side of the vehicle door.
  • the outside open lever rotatably attached to the housing is rotated from an initial position to a rotated position by a door opening operation of an outside door handle arranged at an outer side of the vehicle door.
  • the open link is attached to a connecting portion of the outside open lever so as to be tiltable thereto by a predetermined angle.
  • the connecting portion of the outside open lever shifts in accordance with the rotation of the outside open lever.
  • the open link includes an engagement portion (pressing portion) engageable with an engagement portion included in a lift lever of the latch mechanism.
  • the double-locking door lock apparatus further includes first and second operation mechanisms (lock and double lock mechanisms).
  • the lock mechanism switches the open link between an unlocked state where the open link is engageable with the lift lever and a locked state where the open link is not engageable with the lift lever.
  • the double lock mechanism switches a condition of the vehicle door between a double locked state where the locked state by the lock mechanism is noncancelable and a double-lock cancelled state where the double locked state is cancelled.
  • a lock lever portion including a lock operation lever and a latched lever switches an active lever of the lock mechanism between locked and unlocked positions.
  • the latched lever formed by a linear steel material is configured to be operationally linkable with and disengageable from a latch lever (double lock lever).
  • the inside open lever engageable with the lock lever portion includes first and second inside levers.
  • the latch lever (double lock lever) is excluded from the double-locking door lock apparatus disclosed in Reference 1; thereby, the double-locking door lock apparatus may serve as a normal door lock apparatus. Further, even when the lock lever portion may be formed by a single member, the normal door lock apparatus may appropriately function.
  • the double-locking door lock apparatus according to Reference 1 has a complex configuration in a manner to include the lock lever portion formed by the lock operation lever and the latched lever (such complex configuration may be unnecessary for the normal door lock apparatus). Accordingly, components used in the double-locking door lock apparatus according to Reference 1, which is provided with the double lock mechanism, may not be simply applied to the normal door lock apparatus that is not provided with the double lock mechanism.
  • the active lever is maintained in the locked position and is not rotated or moved. Accordingly, the vehicle door in a locked state may be restrained from being unwantedly operated and unlocked from the outer side of the vehicle by the unauthorized means; however, such unwanted unlocking operation may not be detected by utilizing a position switch attached to the active lever because the active lever is not rotated (the position switch is usually provided for detecting whether the vehicle door is locked or unlocked).
  • a double-locking door lock apparatus for a vehicle includes a latch mechanism attached to a vehicle door together with a housing, including a lift lever, and retaining the vehicle door in a closed state relative to a vehicle body, an inside open lever rotatably attached to the housing and rotating from an initial position to a rotated position in accordance with a door opening operation of an inside door handle arranged at an inner side of the vehicle door, an outside open lever rotationally attached to the housing and rotating from an initial position to a rotated position in accordance with a door opening operation of an outside door handle arranged at an outer side of the vehicle door, an open link attached to a connection portion of the outside open lever so as to tilt by a predetermined angle, the connection portion shifting in accordance with the rotation of the outside open lever, the open link including a pressing portion engageable with an engagement portion of the lift lever, the open link being moved toward the lift lever when the inside open lever rotates from the initial position to the rotated position or when the outside open lever rotates from the initial position
  • the double-locking door lock apparatus configured as above, other components except for components of the double lock mechanism (the double lock lever linking with the open link, a components switching the double lock lever between the unset position and the set position, and the like) are identical to components used in a normal lock apparatus that does not include the double lock mechanism. Accordingly, the other components of the double-locking door lock apparatus except for the components of the double lock mechanism are simply utilized in both the double-locking door lock apparatus and the normal door lock apparatus. Consequently, both the double-locking door lock apparatus and the normal door lock apparatus may be manufactured at low cost.
  • the double lock lever operates together with the open link that is in the locked position.
  • the locking/unlocking member is unwantedly operated and unlocked from an outer side of the vehicle by unauthorized means, for example, without the use of a key; therefore, the active lever shifts from the locked position to the unlocked position.
  • the double lock lever is maintained in the set position while engaging with the open link, thereby restraining the open link from shifting from the locked state to the unlocked state.
  • the open link is maintained in the locked state, therefore restraining the unwantedly unlocking operation from the outside of the vehicle.
  • the active lever in the locked position shifts to the unlocked position.
  • a position switch arranged at the active lever is operated to thereby detect that the vehicle door in the locked state is unwantedly operated and unlocked from the outer side of the vehicle (the position switch is generally arranged at the active lever in order to detect whether the vehicle door is locked or unlocked).
  • the double lock lever is movably attached to the housing along a guide formed in the housing, and one end portion of the double lock lever is moved toward an engagement arm portion, which is formed at the open link, so that the double lock lever engages with the open link when the double lock lever is in the set position.
  • the double lock lever is movably attached to the housing along a guide formed in the housing, and a lower end portion of the double lock lever is moved toward an engagement arm portion, which is formed at the open link, so that the double lock lever engages with the open link when the double lock lever is in the set position.
  • the double lock lever may be simply formed by a bar-shaped member and a space for the double lock lever in the housing may be minimized.
  • the guide is formed in the housing so as to extend obliquely downward in a vertical direction of the vehicle.
  • a distance in which the double lock lever moves along the guide may be shorten compared to a case where the guide extends straight in the vertical direction in housing.
  • a spring arranged between the outside open lever and the open link, the spring biasing the open link so as to bring the open link into the unlocked state and retaining the open link in a manner that the open link is movable relative to the lift lever so as to return to an initial position, an unlocked state retaining guide retaining the open link in the unlocked state when the active lever is in the unlocked position and the outside open lever rotates between the initial position and the rotated position, a locked state retaining guide retaining the open link in the locked state when the active lever is in the locked position and the outside open lever rotates between the initial position and the rotated position, and a pressing arm portion arranged at the active lever, the pressing arm portion engaging with the open link in the unlocked state by the displacement of the active lever from the unlocked position to the locked position and allowing the open link to tilt, the pressing arm portion disengaging from the open link in the locked state so as to shift the open link to the unlocked state.
  • the outside door handle is operated at the same time as the unlocking operation of the locking/unlocking member is performed operated.
  • the vehicle door is brought into a state where unlocking operation may not be implemented appropriately (such state is referred to as a panic state).
  • the open link is movably supported by the spring relative to the lift lever and is allowed to return to an initial position. Accordingly, the outside open lever is returned to the initial position even when the panic state occurs; therefore, the open link returns to the initial position while shifting from the locked state to the unlocked state.
  • the double-locking door lock apparatus may smoothly shift the vehicle door from the locked state to an unlocked state.
  • a plane surface on which a main portion of the lift lever rotates is arranged in parallel to a plane surface on which a main portion of the open link tilts, and a pressing leg portion is arranged at the lift lever and a passive portion is arranged at the open link.
  • the pressing leg portion of the lift lever is arranged so as to press the passive portion of the open link when the vehicle door in an opened state is operated to a closed state under a condition where the active lever is in the locked position and the outside open lever is in the initial position.
  • the vehicle door in the opened state is set to the looked state by shifting the active lever from the unlocked position to the locked position by means of the locking operation of the locking/unlocking member. Then, the vehicle door in the opened state is operated to the closed state without the operation of the outside door handle. At this time, the pressing leg portion of the lift lever presses the passive portion of the open link, therefore shifting the open link from the locked state to the unlocked state and moving the active lever from the locked position to the unlocked position. Accordingly, the vehicle door in the locked state while being in the opened state is operated to the closed state, thereby automatically cancelling the locked state of the vehicle door.
  • the surface on which the main portion of the lift lever rotates is arranged in parallel to the surface on which the main portion of the open link rotates.
  • the pressing leg portion is arranged at the lift lever and the passive portion is arranged at the open link, Accordingly, the aforementioned automatic cancellation of the locked state of the vehicle door may be performed and may be simply provided to the double-looking door lock apparatus at low cost without additional components.
  • a pressing arm portion is arranged at the inside open lever and a passive portion is arranged at the active lever.
  • the pressing arm portion of the inside open lever is arranged so as to press the passive portion of the active lever when the vehicle door in the closed state is operated to the opened state under a condition where the active lever is in the locked position and the inside open lever is in the initial position.
  • the door opening operation of the inside door handle is performed under a condition where the vehicle door is in the closed state and the active lever is in the locked position. Then, the inside open lever is moved in a direction to open the vehicle door; therefore, the pressing arm portion of the inside open lever presses the passive portion of the active lever. Accordingly, the active lever is shifted from the locked position to the unlocked position and the open link is moved from the locked state to the unlocked state.
  • the vehicle door in the locked state while being in the closed state may be automatically unlocked by the door opening operation of the inside door handle; therefore, a so-called one-motion function or a double-pull function (unlocking function) may be obtained.
  • the pressing arm portion is arranged at the inside open lever and the passive portion is arranged at the active lever; thereby, the one-motion function or the double-pull function may be realized without additional components. Accordingly, the one-motion function or the double-pull function may be simply obtained at low cost.
