The elastic pre-tightening force can be an elastic force generated by compression of the compression spring, an elastic force generated by twisting of the torsion spring, an elastic force generated by extension of the tension spring and the like. Optionally, the rocker assembly 20 rotates away from the limiting frame 11 under the action of the elastic pre-tightening force.

Optionally, the driving slot 311 is a long hole, the driving slot 311 includes two opposite and parallel side walls, and the transmission shaft 41 is tangent to the side walls.
When the car door is opened, the rocker assembly 20 rotates relative to the door vane bottom plate 12 under the drive of the motor synchronous belt, the latch plate 31 rotates relative to the rocker assembly 20, and the latch body 33 abuts against the limiting frame 11 under the action of the elastic pretightening force of the first reset assembly 32 and moves towards the car door opening direction together until the knife arm hinge assembly 40 rotates away from the limiting frame 11 when being located at the clamping position.

For example, the linear sliding distance of the latch plate 31 with respect to the stopper 11 is 8mm to 16mm so that the latch body 33 is not locked to the hook at the initial stage of opening the car door. Specifically, the linear sliding distance of the latch plate 31 in cooperation with the limiting frame 11 is 8mm, 10mm, 12mm, 15mm, 16mm, or the like.

The latch hook plate 31 is rotatably connected to the rocker assembly 20, so that the latch hook body 33 abuts against the limiting frame 11 at the initial stage of door opening and moves along the direction departing from the door opening direction, the spacing between the latch hook body 33 and a fixed hook on a door machine of the car door is basically kept stable, and the problem of locking caused by the reduction of the spacing between the latch hook body 33 and the fixed hook is avoided. Similarly, the latch body 33 is rotatably abutted to the stopper 11 when the latch plate 31 is rotated to the closed position relative to the rocker assembly 20 to lock the latch hook and prevent the latch hook from being impacted.

In one embodiment, the synchronous vane device further comprises a return limit assembly 50 rotatably connected to the vane base plate 12, wherein the return limit assembly 50 is slidably connected to the rocker assembly 20. When the knife arm hinge assembly 40 is in the clamping position, the return limit assembly 50 pushes against the rocker assembly 20 so that the rocker assembly 20 cannot rotate.

In another embodiment, as shown in fig. 9 and 10, left and right knife arms 45 and 42 open the clamp door lock ball to be in an unlocked state. The left knife arm 45 and the right knife arm 42 are relatively opened along with the rotation of the upper swing rod 43 so as to clamp a door lock ball positioned on the landing door device, so that the car door lock hook assembly is unlocked to lock the car door machine, and the car door lock is in an unlocked state; or, the left knife arm 45 and the right knife arm 42 are relatively folded along with the rotation of the upper swing rod 43 so as to release the door lock ball clamped on the landing door device, so that the car door lock hook assembly is locked on the car door machine to be in a locking state.
The working principle and the process of the synchronous car door lock hook are briefly described as follows:
door closing in-place state of the door machine: after the door machine is closed in place, the in-place baffle 60 fixedly connected to the bottom plate of the door machine is abutted against the pushing frame 24 of the rocker assembly 20, and the in-place baffle 60 pushes the pushing frame 24 in the opposite direction to drive the rocker assembly 20 to rotate anticlockwise around the rotation center of the rocker assembly until reaching the limiting position. When the rocker assembly 20 rotates counterclockwise relative to the door frame assembly 10, the rocker frame 21 drives the door latch hook assembly 30 to rotate around the second rotating member 23. Meanwhile, the latch plate 31 can only slide in a linear manner similar to horizontal retraction under the elastic force action of the first restoring component 32 and the limiting action of the limiting frame 11 on the door vane bottom plate 12. Moreover, the latch plate 31 drives the knife arm hinge assembly 40 and the rocker assembly 20 to rotate counterclockwise through the driving slot 311, and the knife arm hinge assembly 40 changes from a knife retracting and ball clamping state to a knife expanding state; the blade arm hinge assembly 40 (left blade arm 45& right blade arm 42) is separated from the door lock locking ball, and the hook plate 31 falls down and is locked with the stationary hook. It should be noted that in the present application, clockwise is determined from the plane of the blade arm hinge assembly 40 in the synchronous door blade device as a front face.
The door opening and closing process state of the door machine is as follows:
when the door machine opens the door, the pushing frame 24 of the rocker assembly 20 and the in-place baffle 60 are separated, and the rocker assembly 20 rotates clockwise along with the increase of the door opening gap until reaching the limiting position. During this process, the rocker assembly 20 will drive the latch plate 31 to slide toward the door closing direction (the sliding principle is the same as above). The sliding distance of the latch plate 31 can be approximately the same as the door opening distance of the door machine, so that the position of the latch plate 31 in the rotation stroke of the rocker assembly 20 is kept relatively unchanged, the barb part 332 of the latch body 33 and the fixed hook keep a relatively stable gap, and the problem of locking is avoided. When the latch plate 31 slides in the door closing direction, the latch plate 31 drives the knife arm hinge assembly 40 to rotate clockwise, and the door knife starts to retract. When the knife arm hinge assembly 40 (the left knife arm 45 and the right knife arm 42) is contacted with the landing door lock ball and the knife is continuously retracted, the knife arm hinge assembly 40 can rotate anticlockwise under the reverse acting force of the landing door lock ball; and the transmission shaft 41 connected with the upper swing link 43 drives the latch plate 31 to rotate counterclockwise, so as to open the car door latch hook assembly 30. After the rocker assembly 20 is rotated to the limit position, the locking member 52 of the return limit assembly 50 may limit the rocker assembly 20 from rotating counterclockwise. At the moment, the door knife finishes the door knife retracting of the cutter clamping ball, and drives the landing door to finish door opening and door closing together under the action of the door machine.
