The unlocking process of the latch hook assembly 4 will be described with reference to fig. 8 to 17.

Regardless of whether the door is opened normally or is opened, before the door is opened, the elevator car first moves to the landing.

When the door is normally opened, the elevator car moves to a landing with the vane assembly 2 in a closed state (see the first drawing of fig. 8), and the guide device 31 is located near the first folding plate 102 (see fig. 9 and 11).

Under the driving of the conveyor belt, the guide device 31 is translated along the guide rail 104 to the second bending plate 103 (see fig. 13, 14 and 16), during this translation, the first end 61 of the pull rod 6 moves horizontally along with the guide assembly 3, the second end 62 of the pull rod 6 drives the vane assembly 2 to open (see the first drawing of fig. 13), the vane assembly 2 can hit the hall door ball 900 after opening, the hall door ball 900 applies a reverse force to the vane assembly 2, and the vane assembly 2 is closed (see the first drawing and the second drawing of fig. 13, and fig. 14 to 17). The first diagram of fig. 13 is a schematic diagram before the closing action of the door knife assembly 2 in the open state, the second diagram of fig. 13 is a schematic diagram after the closing action of the door knife assembly 2 in the open state, and in fig. 13, a dashed comparison line is added to more clearly illustrate the position change of the door knife assembly 2 before the closing action and after the closing action.

When the closing action of the door vane assembly 2 occurs, the first link 23 of the door vane assembly 2 rotates in the counterclockwise direction of fig. 13 (i.e., rotates in the clockwise direction of fig. 14 to 17), and the guide 31 at this time no longer moves, so that the pull rod 6 no longer moves and rotates.

The first linear groove 22 of the first link 23 has a length such that the first linear groove 22 of the first link 23 can rotate with respect to the second shaft 63 of the drawbar 6.

Specifically, the first link 23 rotates from a state where the bottom end 222 of the first linear groove 22 contacts the second shaft 63 of the tie bar 6 (see the first drawing of fig. 13) to a state where the top end 221 of the first linear groove 22 contacts the second shaft 63 of the tie bar 6 (see the second drawing of fig. 13).

During the rotation of the first link 23, the extension shaft 21 of the first link 23 can rotate downward along the arc-shaped groove 101 of the base plate 1 (see fig. 16 and 17 in a matching manner), and the second strip-shaped groove 51 of the lifting plate 5 drives the lifting plate 5 to rotate around one end 53 of the lifting plate 5 (i.e., the end of the lifting plate 5 hinged to the pull rod 6), and the arc portion 52 of the lifting plate 5 drives the first shaft 41 of the latch hook assembly 4 to rotate upward (see fig. 16 and 17 in a matching manner), so as to push the latch hook assembly 4 to rotate around the rotation center (i.e., the rotation shaft 422) of the latch hook assembly 4 in the counterclockwise direction of fig. 16, thereby unlocking the latch hook assembly 4.

As described above, no matter the car or the landing takes off the door, the door vane assembly 2 is closed, and when the door is taken off, the door vane assembly 2 may be in two states, one is that the elevator is powered on, the door vane assembly 2 is in a closed state, and the other is that the elevator is powered off, and the door vane assembly 2 is in an open state.

When the elevator is powered off, the door vane assembly 2 is in an open state (see fig. 13 in a matching manner), at this time, a maintenance person takes the door, the door vane assembly 2 performs a closing action (from the first drawing in fig. 13 to the second drawing in fig. 13), and an unlocking process after the door vane assembly 2 is closed is the same as an unlocking process of the door vane assembly 2 performing the closing action during normal door opening, and details are not repeated here.

When the elevator is powered on, the door vane assembly 2 is in a closed state (see fig. 8), and before the door is opened, the guide device 31 is positioned close to the first bending plate 102 (see fig. 9 and 11), and when a serviceman opens the door, the door vane assembly 2 is further closed (from the first diagram of fig. 8 to the second diagram of fig. 8). The first diagram of fig. 8 is a schematic diagram of the door vane assembly 2 in the closed state before the action of further closing, the second diagram of fig. 8 is a schematic diagram of the door vane assembly 2 in the closed state after the action of further closing, and in fig. 8, a dashed comparison line is added to more clearly illustrate the position change of the door vane assembly 2 before and after the action of closing.

When the closing action of the door vane assembly 2 occurs, the first link 23 of the door vane assembly 2 rotates in the counterclockwise direction of fig. 8 (i.e., rotates in the clockwise direction of fig. 9 to 12), and the guide 31 at this time no longer moves, so that the pull rod 6 no longer moves and rotates.

The rotation process of the first link 23 is similar to that in the normal door opening process, and is not described in detail here.

In the rotating process of the first connecting rod 23, the extending shaft 21 of the first connecting rod 23 can rotate downward along the arc-shaped groove 101 of the base plate 1 (see fig. 11 and 12 in a matching manner), and the second strip-shaped groove 51 of the lifting plate 5 drives the end 53 (i.e., the end of the lifting plate 5 hinged to the pull rod 6) of the lifting plate 5 to rotate, and the arc-shaped portion 52 of the lifting plate 5 drives the first shaft 41 of the latch hook assembly 4 to rotate upward (see fig. 11 and 12 in a matching manner), so as to push the latch hook assembly 4 to rotate around the rotation center (i.e., the rotating shaft 422) of the latch hook assembly 4 in the counterclockwise direction of fig. 11, thereby unlocking the latch hook assembly 4.

No matter the door is taken off by the car or the landing, and no matter when taking off the door, the door knife component 2 is in an open state (namely the elevator is powered off) or a closed state (namely the elevator is powered on), or normally opens the door, acting force is applied to the door knife component 2 through the landing door ball 900, so that the door knife component 2 generates a closed action, the door knife component 2 rotates through driving the lifting plate, and then the locking hook component 4 rotates, so that unlocking is realized.

In an exemplary embodiment, the above-described coupe doorvane door lock structure further comprises: a stopper plate 7, as shown in fig. 6, 18 and 19, the stopper plate 7 being pivotably mounted to the second side of the base plate 1, a first end 71 of the stopper plate 7 being connected to the base plate 1 by a stopper plate spring 72 so as to be mounted to be elastically restored, a second end 73 of the stopper plate 7 being provided with a roller 74, the roller 74 locking the guide assembly 3 after the stopper plate 7 is elastically restored; the third end 75 of the limiting plate 7 is provided with a protrusion 76 extending in a direction away from the roller 74, and the protrusion 76 drives the limiting plate 7 to rotate under the action of external force, so as to unlock the guiding assembly 3 from the roller 74.

Specifically, when the door vane assembly 2 slides down or ascends to a landing, a striker (not shown) on the suspension assembly of the hall door contacts the protrusion 76 and applies a horizontal force to the protrusion 76, which pushes the protrusion 76 to rotate upward with respect to the rotation center 77 of the stopper plate 7, so that the roller 74 rotates downward, thereby releasing the lock of the roller 74 to the guide assembly 3 (see fig. 19).

Specifically, the roller 74 is caught in the right-angled catching groove 312 (see fig. 18) of the guide 31 after the retainer plate 7 is elastically restored, so as to lock the guide 31 of the guide assembly 3.
