Background
The elevator door machine comprises a car door which goes up and down along with the elevator car and landing doors of all floors, and the car door and the landing doors are connected through a door knife mechanism. The door knife mechanism is used for transmitting the driving force of the car door opening and closing door to the layer door part which is opened and closed passively, so that the synchronous opening and closing of the inner and outer double-layer doors of the elevator are realized. Specifically, a door knife mechanism is arranged on the car door, and a gate ball is arranged at the corresponding position of the landing door; when the elevator needs to open the door, firstly, a crank on the door vane mechanism needs to be driven to act to clamp a door ball, and then the car door drives the landing door to open and close synchronously; when the elevator is closed in place, the crank on the door vane mechanism needs to be driven to move in the opposite direction to loosen the door ball, and then the car door can be lifted to other floors. The traditional elevator door motor is driven by a rotating motor, is converted into linear motion of a belt through an intermediate speed reduction and conversion mechanism, and then the belt is connected with an upper crank of a door knife mechanism, so that the door opening and closing and the door knife mechanism are sequentially operated. The transmission mechanism is complex, low in efficiency, poor in precision, long in belt length, high in tensioning force, frequent in reversing, easy to age the belt and frequent in replacement and maintenance.
The elevator door motor driven by the linear motor has the advantages of simple transmission mechanism, high efficiency, high precision, high reliability and the like, and is a future development trend.

The patent CN113023534A proposes a solution to this problem, in which a linear motor rotor is slidably connected to a car door hanging plate through a guide rail, and the motor rotor and a door knife mechanism are connected by a connecting rod via a crank to form a slider-crank mechanism, so as to solve the problem of the linear motor driven door knife mechanism of an elevator door. However, the rotor of the linear motor is still connected to the car door hanging plate, on one hand, the linear motor cannot be designed into a closed structure, and foreign matters and scrap iron in an elevator shaft are easily adhered to the magnetic steel of the stator of the linear motor, so that the normal operation of the linear motor is influenced; on the other hand, the guide precision of the pulley and the guide rail on the car door hanging plate is low, the bounce is large, the elevator door plate often vibrates and collides to easily cause front and back deflection, the air gap between the linear motor stator and the rotor is difficult to ensure the uniformity due to the reasons, and the motor thrust fluctuation is large.

Wherein, the number of the movable components is 3, which are respectively an upper crank 12-1, a connecting rod 11-2 and a movable sliding plate 10-5 of the door knife mechanism 12; the low pair quantity is 4, including 1 sliding pair and 3 revolute pairs: the sliding mechanism comprises a sliding pair consisting of a movable sliding plate 10-5 and a base 10-1, a rotating pair consisting of a connecting rod 11-2 and a first connecting shaft 11-1, a rotating pair consisting of a connecting rod 11-2 and a second connecting shaft 11-3, and a rotating pair consisting of a door knife mechanism upper crank 12-1 and a door knife bottom plate 12-5.

Fig. 1 is a view of the elevator door motor of the embodiment 1 in an open state, in which the door vane mechanism 12 clamps the door ball 21 and the upper crank 12-1 of the door vane mechanism 12 is at the leftmost position. The knife upper crank 12-1 is now rigid and cannot rotate due to the knife moving hook 12-6 in the knife mechanism 12. When the first linear motor module 10 is driven, the driving force is sequentially transmitted to the upper crank 12-1 of the door knife mechanism, the door knife bottom plate 12-5 and the left car door hanging plate 14 through the connecting rod mechanism 11, so that the left door plate 17 is driven to move, the landing door device is driven to synchronously move through the door ball 21, and the right door plate 18 is driven to synchronously move through the linkage device 19.

Therefore, all the actions of closing the door are completed, the elevator can run to the next floor for cycle work, and the door opening action and the door closing action are completely opposite.
To sum up, the specific working process of the elevator door machine in the embodiment 1 of the invention is as follows: when the door is closed, because the upper crank 12-1 of the door knife mechanism 12 is in a rigid state incapable of rotating, the rotor 10-3 of the linear motor component firstly drives the left door panel 17 to move, and drives the right door panel 18 and the landing door device to synchronously move under the action of the linkage device 19 and the door knife mechanism 12; after the left door plate 17 and the right door plate 18 close the door, the upper crank 12-1 of the door knife mechanism 12 is changed into a rotatable flexible state, the mover 10-3 of the linear motor assembly needs to move for a section along the first linear guide rail 10-8 continuously, the upper crank 12-1 of the door knife mechanism 12 is driven to rotate clockwise through the connecting rod mechanism 11, and the door ball 21 is released (at the moment, the left door plate and the right door plate are not moved); when the door is opened, the rotor 10-3 of the linear motor assembly firstly needs to reversely move for a section along the first linear guide rail 10-8, the upper crank 12-1 of the door knife mechanism 12 is driven to rotate anticlockwise through the connecting rod mechanism 11, the door ball 21 is clamped (at the moment, the left door plate and the right door plate are not moved), then the left door plate and the right door plate and the landing door device are driven to be synchronously opened, and the operation is circulated.
