  • the super lock function may be provided along with the manual child lock function.
  • the door lock devices have several different specifications, the door lock devices mostly have the same basic structures, and therefore, it is preferable to use as many common parts as possible among the door lock devices, so that the different specifications can be implemented merely by replacing or adding some parts.
  • the door lock device disclosed in Patent Document 1 has a recessed surface recessed inwards, and therefore, has a smaller inner space accordingly. Hence, the door lock device may have no extra spatial allowance for mounting any additional parts, or the shapes of the parts to be additionally amounted may be restricted.

  • the door lock device may further includes: a child lock mechanism actuating, when a child lock knob is operated to switch ON, the latch mechanism to disable an operation of opening the door using an inside handle of the vehicle; and a power child lock mechanism electrically operating the child lock mechanism.
  • the power child lock mechanism includes: an electric motor; a power child gear, disposed on an upper side or a lower side of the child lock mechanism, being driven by the electric motor; and a power child link joining the power child gear and the child lock mechanism in the up-and-down direction, the power child link is disposed in an internal space of the bulged portion, the power child link is removable, and the power child gear is replaceable with a super lock gear (76) which is driven by the electric motor to actuate the latch mechanism.
  • the door lock device may further includes: a child lock mechanism actuating, when a child lock knob is operated to switch ON, the latch mechanism to disable an operation of opening the door with an inside handle on the vehicle; and a super lock mechanism actuating the latch mechanism based on an electric operation to disable an operation of opening the door using an outside handle and the inside handle on the vehicle.
  • the super lock mechanism (74) includes: an electric motor; and a super lock gear, disposed on an upper side or a lower side of the child lock mechanism, being driven by the electric motor to actuate the latch mechanism, the super lock gear is replaceable with a power child gear that is driven by the electric motor, a power child link, joining the power child gear and the child lock mechanism in the up-and-down direction, is mountable, and the power child link is disposed in an internal space of the bulged portion.
  • a part of the bulged portion may form a surface including an axis extending in a vehicle width direction.
  • the door lock device according to the present invention has the bulged portion that extends in the up-and-down direction in the housing on the inner side of the cabin, the door lock device is easy-to-hold by hand. Furthermore, a specification change can be made depending on whether the power child link that is positioned in the bulged portion is present or not.

  • the door lock device 10a is somewhat thick in the vehicle width direction on the vehicle rear side because the door latch device 12 is provided on the rear side of the vehicle, but is appropriately thin on the front side of the vehicle. Therefore, it is appropriate to hold the door lock device 10a by the hand H from the front side of the vehicle (see FIG. 2 ). With such design, the door latch device 12 can easily be aligned to a predetermined mounting position of the door.
  • a door lock device 10b according to a second embodiment will now be described with reference to FIG. 8 .

  • the axis 71 supports the super lock gear 76 in the same manner as the power child gear 70.
  • the super lock gear 76 is illustrated as a densely dotted are for easy recognition purposes.
  • the hook 76a becomes engaged with a part of the sub-lever link 40b and restricts the operation of the sub-lever link 40b. By doing this, the door-opening operations by using the outside handle and the inside handle are disabled and the door is in a super-locked state. As the super lock gear 76 is rotated in the counter-clockwise direction by the rotation of the second motor 66, the hook 76a becomes separated from the part engaged with the sub-lever link 40b, and the super-locked state is released.
  • the super lock gear 76 includes a protrusion 76b protruding diagonally downwards toward the front side. A distal end of the protrusion 76b is fitted in and guided along an arc groove 14a which is provided to the casing 14.

  • the child lock lever 78 is illustrated as a lightly dotted area, for easy recognition purposes.
  • the super lock gear 76 can be attached to and removed from the axis 71 and the child lock lever 78 can be attached to and removed from the axis 44.
  • the axis 44 holds not only the child lock lever 78 but also the lock knob lever 52 and the inside lever 56. Since the child lock lever 78 is provided on the frontmost side with respect to the paper surface (on the outer side of the cabin), only the child lock lever 78 can be removed without removing the lock knob lever 52 and the inside lever 56.
  • the super lock gear 76 can also be removed while the worm gear 68 is still attached to the second motor 66.
  • the external appearance of the door lock device 10b is the same as that of the door lock device 10a described above. Therefore, the door lock device 10b can also be held by the hand H easily, with the bulged portion 30 provided to the cover 16 on the side surface of the door lock device 10b, and exhibits excellent workability (see FIG. 2 and FIG. 7 ).
  • the door lock device 10a (see FIG. 5 ) and the door lock device 10b (see FIG. 8 ) have the same structure except that the power child lock mechanism 64 ( FIG.5 ) is replaced with the super lock mechanism 74 ( FIG.8 ). Both the power child lock mechanism 64 and the super lock mechanism 74 have the same second motor 66 and worm gear 68.
  • the door lock device 10a differs from the door lock device 10b in that, while the former is provided with the power child gear 70, the power child link 72, and the child lock lever 62, the latter is provided with the super lock gear 76 and the child lock lever 78. Furthermore, each of the elements are removable.
  • the specifications of the door lock device 10a provided with the power child lock mechanism 64 can be changed to those of the door lock device 10b that is provided with the super lock mechanism 74, by removing the power child link 72, replacing the power child gear 70 with the super lock gear 76, and replacing the child lock lever 62 with the child lock lever 78.
  • the child lock lever 62 may be used as it is.
  • the specifications of the door lock device 10b that is provided with the super lock mechanism 74 can be changed to those of the door lock device 10a that is provided with the power child lock mechanism 64, by replacing the super lock gear 76 with the power child gear 70, replacing the child lock lever 78 with the child lock lever 62, and joining the power child link 72 between the power child gear 70 and the child lock lever 78.
  • the door lock device 10a can be manufactured simply by attaching the child lock lever 62, the power child gear 70, the power child link 72, the cover 16, and the waterproofing cover 20, when the door lock device 10a is required, and the door lock device 10b can be manufactured simply by attaching the super lock gear 76, the child lock lever 78, the cover 16, and the waterproofing cover 20, when the door lock device 10b is required.
  • the door lock device 10a and the door lock device 10b enable an easy and quick specification change, simply by the replacement of some parts. Furthermore, because the bulged portion 30 is provided to the position where the power child link 72 is to be provided, the door lock device can be held easily by the hand H. Because the bulged portion 30 is provided in accordance with the shape of the power child link 72, no restriction is imposed on the shape of the power child link 72.
