For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] like Figures 1 to 12As shown, this embodiment provides a double-folding door elevator door operator device, including a door operator base plate 10 and a drive component 20, a transmission component 100 and a linkage door hanging plate assembly 30 disposed on the door operator base plate 10. The linkage door hanging plate assembly 30 includes a first door hanging plate 31, a second door hanging plate 32 and a linkage component 33 connecting the first door hanging plate 31 and the second door hanging plate 32. The first door hanging plate 31 is provided with a car door lock device 18. The first door hanging plate 31 is configured to be driven by the drive component 20 through the transmission component 100 when the car door lock device 18 is in the unlocked state, and to drive the second door hanging plate 32 to perform door opening and closing movements. The first door mounting plate 31 is provided with a first abutting part 311, and the second door mounting plate 32 is provided with an extension plate 321 extending toward the first door mounting plate 31, and the extension plate 321 is provided with a second abutting part 322; wherein, the first abutting part 311 is located behind the second abutting part 322, and the first abutting part 311 is used to restrict the second abutting part 322 from moving toward the door opening direction X when the linkage component 33 fails.

[0024] Specifically, in the door system, the direction closer to the closing position is the front side, and the direction farther from the closing position is the rear side. That is, in the closing direction, the first abutment 311 is located behind the second abutment 322.

[0025] This embodiment establishes a direct and inevitable mechanical pushing relationship between the first door hanging plate 31 and the second door hanging plate 32 by setting the first abutting part 311 and the second abutting part 322. When the first door hanging plate 31 moves to the abutting position, the second door hanging plate 32 will be pushed immediately and without delay. This embodiment ensures the synchronization of the first door hanging plate 31 and the second door hanging plate 32 during the closing process, making the door movement smoother and more precise, and reducing impact and noise.

[0026] Meanwhile, compared to traditional solutions that rely on slow-door contact switches for detection and triggering, this embodiment completely eliminates faults such as asynchronous operation of the second door latch 32, door closing failure, or even system shutdown caused by electrical switch failure, greatly improving the reliability and safety of elevator operation. Furthermore, this embodiment eliminates any delay in the transmission and processing of electrical signals, ensuring absolute synchronization between the first door latch 31 and the second door latch 32 during the door closing process.

[0027] In one embodiment, the second abutment portion 322 is hook-shaped.

[0028] In one embodiment, the drive unit 20 is a permanent magnet synchronous motor.

[0029] In one embodiment, the drive unit 20 is equipped with a controller, which is a permanent magnet synchronous gantry controller.

[0030] In one embodiment, an internal clamping car door lock is provided on the first door mounting plate 31. The internal clamping car door lock includes a mechanical interlocking component and an electrical interlocking component, wherein the housing protection level of the electrical interlocking component is IP20.

[0031] like Figure 1 As shown, in one embodiment, a first guide rail 40 and a second guide rail 50 are provided on the door operator base plate 10, a first door hanging plate 31 is provided on the first guide rail 40, and a second door hanging plate 32 is provided on the second guide rail 50; a gap 11 is formed between the first guide rail 40 and the door operator base plate 10, and the second door hanging plate 32 is located within the gap 11.

[0032] This embodiment achieves precise guidance of the movement paths of the first door mounting plate 31 and the second door mounting plate 32 by setting the first guide rail 40 and the second guide rail 50. This ensures that the second door mounting plate 32 is located within the gap 11 between the door operator base plate 10 and the first guide rail 40, cleverly embedding the second door mounting plate 32 into the three-dimensional space formed by the first guide rail 40 and the door operator base plate 10. This makes the entire door operator device more compact, helping to reduce the overall size and space occupied by the equipment. Simultaneously, it ensures the independence and stability of the first and second door mounting plates 32 running on their respective tracks, avoiding movement interference.

[0033] like Figure 3 and Figure 4 As shown, in one embodiment, the door operator base plate 10 is provided with an opening limit member 12 and a first closing limit member 13 for abutting against the first door hanging plate 31. The opening limit member 12 and the first closing limit member 13 are respectively located at both ends of the first guide rail 40. The door operator base plate 10 is provided with a second closing limit member 14 for abutting against the second door hanging plate 32. The second closing limit member 14 is located between the opening limit member 12 and the first closing limit member 13.

[0034] Specifically, the door opening limiter 12, the first door closing limiter 13, and the second door closing limiter 14 are spherical.

[0035] In this embodiment, the first door hanging plate 31 (shutter) is limited to the end point of travel by the door opening limiter 12 and the first door closing limiter 13, while the second door closing limiter 14, which is located between the two, is specifically used to limit the final closing position of the second door hanging plate 32 (slow shutter).

[0036] This application, by adding an opening limiter 12, a first closing limiter 13, and a second closing limiter 14, ensures that the first door hanging plate 31 and the second door hanging plate 32 can be accurately and reliably positioned at the end of the closing process, effectively preventing incomplete closing or collision impact caused by inertia or error, and improving the termination accuracy and long-term reliability of the door system operation.

[0037] In one embodiment, the first guide rail 40 is a cold-drawn guide rail.

[0038] In one embodiment, the lower end of the gantry crane base plate 10 is bent to form a second guide rail 50.

[0039] like Figure 13 As shown, in one embodiment, two end sealing plates are respectively provided at both ends of the door operator base plate 10, namely the first end sealing plate 15 and the second end sealing plate 16. The door opening limiter 12 and the first door closing limiter 13 are respectively located on the first end sealing plate 15 and the second end sealing plate 16, and the two ends of the first guide rail 40 are respectively provided on the first end sealing plate 15 and the second end sealing plate 16.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in another embodiment, two end sealing plates are respectively provided at both ends of the door operator base plate 10, namely the first end sealing plate 15 and the second end sealing plate 16. A support member 17 is also provided on the door operator base plate 10, which is located adjacent to the second end sealing plate 16. The door opening limit member 12 is provided on the first end sealing plate 15, and the first door closing limit member 13 is provided on the support member 17. The two ends of the first guide rail 40 are respectively provided on the first end sealing plate 15 and the support member 17.

[0041] Specifically, the first end plate 15, the second end plate 16, and the support member 17 all extend from the door machine base plate 10 in a direction away from the door machine base plate 10, so that a gap 11 is formed between the first guide rail 40 and the door machine base plate 10 to accommodate the second door hanging plate 32.

[0042] In this embodiment, one end of the door opening limiter 12 and the first guide rail 40 is integrated onto the first end plate 15, and the other end of the first closing limiter 13 and the first guide rail 40 is integrated onto the second end plate 16 or the support member 17. During assembly, this embodiment facilitates one-time adjustment of the relative positional accuracy between the limiter and the guide rail, significantly improving assembly efficiency and reducing errors accumulated from multiple, dispersed installations, thereby ensuring the overall accuracy and consistency of the door operator's operation. It also simplifies the overall structural layout and processing steps of the door operator's base plate 10.

[0043] like Figure 3 As shown, in one embodiment, the end sealing plate connected to the first guide rail 40 includes a fixing part 151, a connecting part 152, and a supporting part 153 formed in sequence. The door opening limiter 12 and the first guide rail 40 are disposed on the supporting part 153, the fixing part 151 is disposed on the door operator base plate 10, the upper end of the connecting part 152 contacts the upper end of the door operator base plate 10, and the lower end of the connecting part 152 is connected to the supporting part 153.

[0044] Specifically, when the two ends of the first guide rail 40 are respectively disposed on the first end sealing plate 15 and the second end sealing plate 16, the first end sealing plate 15 and the second end sealing plate 16 both have a structure including a fixing part, a connecting part and a supporting part formed in sequence.

[0045] Specifically, when the two ends of the first guide rail 40 are respectively disposed on the first end plate 15 and the support member 17, the first end plate 15 has a structure including a fixing part, a connecting part and a support part formed in sequence.

[0046] In this embodiment, the connecting part 152 contacts the upper end of the gantry crane base plate 10 to achieve surface contact or line contact. This can more effectively resist the vibration and torque generated during the operation of the gantry crane, prevent the gantry crane base plate 10 and the support from loosening or deforming, and greatly enhance the connection rigidity and stability between the support and the gantry crane base plate 10.

[0047] like Figure 3 As shown, in one embodiment, a first reinforcing rib 154 is provided between the fixing part 151 and the connecting part 152. The two ends of the first reinforcing rib 154 are connected to the fixing part 151 and the connecting part 152 respectively. The first reinforcing rib 154 is triangular or fan-shaped.

[0048] Specifically, there are multiple first reinforcing ribs 154, which are arranged sequentially along the longitudinal direction.

[0049] This embodiment can greatly improve the bending and torsional stiffness of the transition area formed by the connection between the fixing part 151 and the connecting part 152. It effectively suppresses fatigue deformation or even cracking that may occur in the support under long-term cyclic load, significantly enhances the mechanical strength and durability of key structural components, and thus extends the service life of the entire gantry crane.

[0050] like Figure 4 and Figure 5 As shown, in one embodiment, the lower end of the first door hanging plate 31 is bent to form a first hanging door portion 312, and a second reinforcing rib 313 is provided between the first door hanging plate 31 and the first hanging door portion 312; the lower end of the second door hanging plate 32 is bent to form a second hanging door portion 323, and a third reinforcing rib 324 is provided between the second door hanging plate 32 and the second hanging door portion 323.

[0051] Specifically, there are multiple second reinforcing ribs 313, which are arranged sequentially along the transverse direction.

[0052] Specifically, there are multiple third reinforcing ribs 324, which are arranged sequentially along the transverse direction.

[0053] This embodiment enhances the rigidity of the critical load-bearing area at the lower end of the door panel by setting reinforcing ribs between the door panel and the hanging door section. This effectively prevents bending deformation caused by long-term hanging loads on the door panel, ensuring the straightness and stability of the door panel during operation, and also improving the impact resistance of the components.

[0054] Specifically, the second reinforcing rib 313 is triangular or fan-shaped.

[0055] Specifically, the third reinforcing rib 324 is triangular or fan-shaped.

[0056] like Figure 10 and Figure 12 As shown, in one embodiment, the first door hanging plate 31 is provided with a first anti-detachment member 314 and a second anti-detachment member 315. The first anti-detachment member 314 is hooked onto the upper part of the first guide rail 40, and the second anti-detachment member 315 is hooked onto the lower part of the first guide rail 40.

[0057] In one embodiment, the first anti-detachment component 314 and the second anti-detachment component 315 are hook-shaped.

[0058] The second door hanging plate 32 is provided with a third anti-detachment component 325, which is hooked onto the upper part of the second guide rail 50 or the lower part of the second guide rail 50.

[0059] In one embodiment, the third anti-detachment component 325 is hook-shaped.

[0060] This embodiment incorporates an anti-detachment component on the door mounting plate, which constrains the guide rail within it, thus forming a reliable anti-tipping constraint and constituting redundant protection. Even if the door operator system is subjected to abnormal external force impact or severe vibration, it can effectively prevent the door mounting plate from detaching from the guide rail, greatly improving the safety and reliability of the door system operation and preventing potential safety risks.

[0061] like Figure 13 As shown, in one embodiment, there are two linkage door hanging plate assemblies 30, namely a first linkage door hanging plate assembly 60 and a second linkage door hanging plate assembly 70. The first door hanging plate of the first linkage door hanging plate assembly 60 and the first door hanging plate of the second linkage door hanging plate assembly 70 are connected by a follower component 80. The drive component 20 drives the first door hanging plate of the first linkage door hanging plate assembly 60 to move the second door hanging plate of the first linkage door hanging plate assembly 60, and drives the first door hanging plate of the first linkage door hanging plate assembly 60 to move the first door hanging plate and the second door hanging plate 32 of the second linkage door hanging plate assembly 70 through the follower component 80.

[0062] In this embodiment, by setting a follow-up component 80, the first door hanging plate 31 of the two linkage door hanging plate components 30 are connected, realizing the synchronous driving of the two sets of door components by a single drive component 20, and achieving synchronous control of the two side door leaves of the center split double fold door.

[0063] This embodiment significantly simplifies the electrical control and mechanical structure of the door operator, reduces manufacturing costs and energy consumption, and avoids the synchronization error problem that may exist in dual drives, ensuring the consistency and coordination of the door opening and closing actions.
