The door lock structure 10 of this embodiment includes a door lock assembly 13 provided in a back door 12 of a vehicle 11 shown in FIG. 1, a link mechanism 14 for unlocking the door lock assembly 13 from outside the vehicle, and a door lock assembly The striker 15 is engaged with the striker 13 to lock the door.

The door lock assembly 13 includes an abbreviated door lock inside open lever 17 that is rotated in the force direction by pulling the remote control rod 16 in the direction of the arrow G (by rotating the remote control rod 16 in the direction of the arrow I about the fulcrum 17a). The door opening lever 18 is rotated in the direction of arrow 1 about a fulcrum 18a by an open lever, and is always urged in the direction opposite to the direction of arrow 1 by a spring 19. An overhang 20 that is moved in the direction of arrow J by a lever, has a long hole 21 at its lower end 20a, and further pushes down one end 22a of a door lock oven link lever 22, which will be described later.
The door lock is equipped with a door lock open link 20 having a shape 20b, which is rotated in the direction of the arrow about a fulcrum 22b to release the lock, and has an emergency lever 23 at the other end 22c. An open link lever 22 is provided, and a fulcrum 24 is provided.
The door locking lever 24 is provided with a door locking lever 24 which rotates around a and whose upper end 24b is slidably engaged with the elongated hole 21 of the door lock open link 20.

Here, in the link mechanism 14, by pulling the outside handle 25 provided on the outside of the back door 12 toward you, the iron 26 moves downward, and accordingly, the levers 27, 28
is rotated, whereby the remote control rod 16 is moved in the direction of arrow G.

Note that the levers 27 and 28 are fixed to the inner panel 12a of the rear gate 12 (see FIG. 6) via a bracket 29.

The emergency lever 23 is shown in FIGS. 17 and 18.
As shown in the figure, the handle 23a faces into the vehicle through a hole 12b provided in the door lock base plate 12a of the back door 12 so that it can be operated with a finger from the vehicle.

The door lock locking lever 24 is configured to be biased in the direction indicated by the arrow or in the opposite direction by a toggle mechanism using a spring 30.

Also, one end 24c of the door locking lever 24
is connected to a key cylinder 32 via a locking control rod 31.

By rotating this key cylinder 32, the door locking lever 24 can be moved in the direction of the arrow to release the lock, and the door locking lever 24 can be tilted in the opposite direction to the direction of the arrow. It can be set to a locked state.

Here, when in the unlocked state, the protrusion 20b of the door lock open link 20 is located directly above the one end 22a of the door lock open link 22, and in the locked state. In some cases, the protruding portion 20b of the door lock open link 20 is shifted from the position directly above the one end portion 22a of the door lock oven link lenomer 22, and is positioned slightly closer to the center (see FIG. 19). .

Further, in FIG. 5, 33 is a latch, and 34 is a port for introducing the striker 15.

Here, FIG. 14 shows that the striker 15, which has been cut to a certain extent on the vehicle body frame 35 side, is at the door lock release point U1.
15 and 16 show the state in which the striker 15 is engaged with the door lock assembly 13. FIGS.

In addition, in FIGS. 4 to 21, 35 is a door lock control bin, 36 is a door lock control bin,
37 is a door lock open lever bin, 38 is a door lock control lock snap connected to a knob (not shown), and 39 is a door lock control link bin.

Next, the operation of this embodiment will be explained with reference to FIGS. 19 to 21.

In FIG. 19, the solid line indicates the unlocked state, and the two dots IX indicate the locked state. Which of these states is adopted depends on the direction in which the door locking lever 24 is tilted.

FIG. 20 shows the unlocked state, the solid line shows the state before the unlocking operation, and the two-dot chain line shows the state during the unlocking operation. In this unlocking state, by pulling the outside handle 25 as described above, the door lock open link lever 22 is rotated in the direction of the arrow, and the latch 33 and the striker 15 are disengaged. .

FIG. 21 shows the locked state, the solid line shows the state before the lock release operation, and the two-dot chain line shows the state during the lock release action. In this unlocking state, even if the outside handle 25 is pulled, the protruding portion 20b of the door lock open link 20 is displaced from the one end 22a of the door lock open link lever 22. Therefore, the door lock open link lever 22 cannot be rotated in the direction of the arrow, and therefore, even in this case, the locked state is maintained.

In this case, if you want to urgently release the lock from inside the vehicle, insert your finger into the hole L2b of the rear gate 12 and lift the emergency lever 23 in the direction of arrow M (see FIG. 21). Without operating the outside handle 25 or the like, the door lock open link lever 22 can be rotated in the direction of the arrow to immediately release the lock and disengage the latch 33 and the striker X5.

f. As described in detail, according to the lock structure of the present invention,
