The latch hook 30 is rotatably mounted on the engaging base 21, one side of the latch hook 30 is in abutting engagement with the engaging rod 23, and the other side is for interlocking engagement with the lock base 40. The first driving mechanism 50 is connected to the engaging base 21 for driving the engaging device 20 to move along the height direction of the car. The second driving mechanism 60 is connected to the lock base 40, and is used for driving the lock base 40 to move synchronously along the height direction of the car.

As described above with reference to fig. 1, 2, 4 and 5, when the car reaches the landing zone, the main control system receives the landing signal and sends the door opening signal to the door control system, the door control system temporarily stores the door opening command, detects the center height position of the landing door lock roller 110 in the landing zone, calculates the height difference between the center of the engaging device 20 and the center of the landing door lock roller 110, and instructs the first driving mechanism 50 and the second driving mechanism 60 to output torque according to the feeding amount, the first driving mechanism 50 drives the engaging device 20 and the latch hook 30 to move, and the second driving mechanism 60 also drives the latch base 40 to move synchronously until the center height of the engaging device 20 is consistent with the center height of the landing door lock roller. Then, a door opening instruction is called, and the car door moves along the horizontal direction, so that the accurate door opening is realized. After passengers or goods enter and exit the car, the car door is closed. When the car door is completely closed, the car door safety loop is closed, the door control system sends a reset instruction to the first driving mechanism 50 and the second driving mechanism 60, the first driving mechanism 50 drives the tying device 20 and the lock hook 30 to return to the initial position, the second driving mechanism 60 synchronously drives the lock seat 40 to return to the initial position, and then the door closing instruction is transmitted to the main control system, the main control system controls the brake to be released, and the elevator continues to normally run. Thus, when the hall door heights of the floors are inconsistent, the first driving mechanism 50 drives the engaging device 20 and the latch hook 30 to move along the height direction of the car according to the command of the door control system, and the second driving mechanism 60 drives the lock seat 40 to synchronously move along the height direction of the car according to the command of the door control system, so that the center height of the engaging device 20 is always coincident with the center height of the landing door lock roller 110, the upper and lower heights of the landing door lock roller 110 relative to the engaging device 20 are ensured to achieve the centering effect when the door is opened and closed, and the use safety of the elevator is improved. Meanwhile, the tie rod 23 does not need to be lengthened to deal with different landing door heights, so that the parallelism of the tie rod is better controlled, and the mutual collision of the tie rod and a landing door lock roller caused by too small distance between the tie rod and the landing door lock roller is avoided. In addition, when the top layer is not enough and the center height of the landing door lock roller 110 is greater than the center height of the engaging device 20, the first driving mechanism 50 can drive the engaging device 20 and the latch hook 30 to move along the height direction of the car, and the second driving mechanism 60 can drive the lock seat 40 to move along the height direction of the car, so that the engaging device 20, the latch hook 30 and the lock seat 40 do lifting motion to open and close the door.
Referring to fig. 6 and 7, it should be noted that the center height of the engaging device 20 refers to the height of the engaging rod 23 in the engaging device 20 that is in abutting engagement with the latch hook 30, and H is adopted 1 Showing the center height of the tie device 20. The center of the landing door lock roller 110 is the height of the central position of the landing door lock roller, and H is adopted 2 Showing the center height of landing door lock roller 110.
In one embodiment, the elevator car door opener also includes a drive mechanism 10. The transmission mechanism 10 is respectively connected with the first driving mechanism 50 and the second driving mechanism 60, and can drive the first driving mechanism 50 and the second driving mechanism 60 to move towards or away from each other. In this way, the door opening command is called, and after the lock hook 30 is separated from the lock seat 40, the transmission mechanism 10 drives the first driving mechanism 50 and the second driving mechanism 60 to move back to facilitate the door opening; and a door closing instruction is called, and the transmission mechanism 10 drives the first driving mechanism 50 and the second driving mechanism 60 to move in opposite directions, so that the hook lock 30 and the lock seat 40 are conveniently interlocked, and the door is closed.
In this embodiment, the transmission mechanism 10 includes a first pulley assembly and a second pulley assembly, the first driving mechanism 50 is connected to the belt on one side of the first pulley assembly, and the second driving mechanism 60 is connected to the belt on one side of the second pulley assembly. In this way, the first pulley assembly and the second pulley assembly cooperate to drive the first driving mechanism 50 and the second driving mechanism 60 to move in opposite directions or back to back directions.
In one embodiment, referring to fig. 1 and 2, the first drive mechanism 50 is a first linear motor. Specifically, the first driving mechanism 50 includes a first mover 51 and a first stator 52, the first stator 52 is fixedly connected with the transmission mechanism 10, and the first mover 51 is fixedly connected with the fastening base 21 and can move along the height direction of the car under the cooperation of the first stator 52. Alternatively, the first mover 52 is a short primary and the first mover 51 is a long secondary. When the car reaches the leveling zone, the central height position of the landing door lock roller 110 in the leveling zone is detected, the height difference between the center of the fastening device 20 and the center of the landing door lock roller 110 is calculated, and the first stator 52 is instructed to be matched with the first rotor 51 to drive the fastening device 20 and the latch hook 30 to move along the height direction of the car until the landing door lock roller 110 reaches the centering effect relative to the fastening device 20, so that accurate door opening is facilitated. In this way, the first mover 51 and the first stator 52 cooperate to drive the engaging device 20 and the latch hook 30 to do linear motion along the height direction of the car, so that the structure is simple, the motion precision is high, and no backlash exists.
Of course, in other embodiments, the first driving mechanism 50 may also be a pulley assembly, such as a belt fixedly connected to the pulley assembly by the fastening base 21. Alternatively, the first driving mechanism 50 may be a screw module, and the fastening base 21 is fixedly connected to the screw nut.
Further, referring to fig. 1 and 2, the fastening base 21 is fixed to the bottom of the first mover 51. Specifically, the bottom of the tie base 21 is flush with the bottom of the first mover 51.

Further, the first linear motor is flat, and the first linear motor is a single-side linear motor. In the single-sided linear motor, a stator is arranged on one side only, and a magnetic field generated by the single-sided linear motor is in a single-sided magnetic field mode. Since the first linear motor and the engaging device 20 are arranged in a left-right direction, a single-sided linear motor is used.

Specifically, the second driving mechanism 60 includes a second mover 61 and a second stator 62, the second stator 62 is fixedly connected with the transmission mechanism 10, and the second mover 61 is fixedly connected with the lock base 40 and can move along the height direction of the car under the cooperation of the second stator 62. Alternatively, the second stator 62 is a long primary and the second mover 61 is a short secondary. When the car reaches the leveling zone, the central height position of the landing door lock roller 110 in the leveling zone is detected, the height difference between the center of the fastening device 20 and the center of the landing door lock roller 110 is calculated, and the second stator 62 is instructed to be matched with the second rotor 61, so that the lock seat 40 is driven to move to the target position along the height direction of the car, and accurate door opening is facilitated. Thus, through the cooperation of the second rotor 61 and the second stator 62, the lock seat 40 is driven to do linear motion along the height direction of the car, and the structure is simple, the motion precision is high, and no idle return exists.
Of course, in other embodiments, the second driving mechanism 60 may be a pulley assembly, such as a belt with the lock base 40 fixedly connected to the pulley assembly. Alternatively, the second driving mechanism 60 may be a screw module, and the lock base 40 is fixedly connected to the screw nut.
Further, the second linear motor is flat, and the second linear motor is a bilateral linear motor. It should be noted that, the double-sided linear motor is provided with stators at both sides of the mover, the double-sided linear motor can generate a double-sided magnetic field, and the normal suction force between the stators and the mover can be mutually offset. Because the second pulley assembly of the transmission mechanism 10 and the lock seat 40 are arranged front and back, the adoption of the bilateral linear motor is more beneficial to uniform stress.
In one embodiment, the elevator car door machine also includes a ranging sensor for detecting the center height position of landing door lock roller 110 for each landing zone. In this way, it is convenient to calculate the height difference between the center of the fastening device 20 and the center of the landing door lock roller 110, and instruct the feeding amounts of the first driving mechanism 50 and the second driving mechanism 60, so as to ensure that the center height of the fastening device 20 is consistent with the center height of the landing door lock roller 110, and realize accurate door opening.

The second driving mechanism 60 is fixed to the second car hanging plate 80, and the lock base 40 is fixed to the output end of the second driving mechanism 60. As such, the first and second car hanging plates 70 and 80 provide mounting locations for the first and second drive mechanisms 50 and 60, facilitating installation of the first and second drive mechanisms 50 and 60.
In the present embodiment, referring to fig. 1 and 2, the first stator 52 is fixed to the first car hanging plate 70, and the fastening base 21 is fixed to the first mover 51. The second stator 62 is fixed to the second car hanging plate 80, and the lock base 40 is fixed to the second mover 61.

When the hall door heights of the floors are inconsistent, the first driving mechanism 50 drives the engaging device 20 and the latch hook 30 to move along the height direction of the elevator car according to the instruction of the door control system, and the second driving mechanism 60 drives the lock seat 40 to synchronously move along the height direction of the elevator car according to the instruction of the door control system, so that the center height of the engaging device 20 and the center height of the landing door lock roller 110 are always overlapped, the upper and lower heights of the landing door lock roller 110 relative to the engaging device 20 are ensured to achieve the centering effect when the door is opened and closed, and the use safety of the elevator is improved. After centering is completed, the car door moves along the horizontal direction, so that accurate door opening is realized, the adaptability of the elevator car door machine to the height of the hall door is improved, and the tying device 20 is generalized in the production process. Meanwhile, the tie rod 23 does not need to be lengthened to deal with different landing door heights, so that the parallelism of the tie rod is better controlled, and the mutual collision of the tie rod and a landing door lock roller caused by too small distance between the tie rod and the landing door lock roller is avoided.
