[0045] As Figures 1 to 6 shown, this embodiment provides an elevator door system, including:

[0046] The bottom plate 1, a guide rail 11 is formed at the first end of the bottom plate 1;

[0047] The active door hanging plate 2, the passive door hanging plate 3 and the linkage assembly 4, the active door hanging plate 2 and the passive door hanging plate 3 are both slidably arranged on the guide rail 11, the active door hanging plate 2 and the passive door hanging plate 3 are linked through the linkage assembly 4, and a locking device 5 is arranged between the active door hanging plate 2 and the second end of the bottom plate 1, and the locking device 5 is used to lock the active door hanging plate 2 and the passive door hanging plate 3 relative to the bottom plate 1;

[0049] In this embodiment, by arranging the cover plate 6 to cover one or more of at least a part of the active door hanging plate 2, at least a part of the passive door hanging plate 3 and at least a part of the linkage assembly 4, one or more of at least a part of the active door hanging plate 2, at least a part of the passive door hanging plate 3 and at least a part of the linkage assembly 4 are separated from the outside world, avoiding interference between other structures of the elevator system and the active door hanging plate 2, the passive door hanging plate 3 and the linkage assembly 4, ensuring the stable operation of the elevator door system, improving the stability of the elevator door system, and reducing the safety risk.

[0050] At the same time, arranging the cover plate 6 can protect the active door hanging plate 2, the passive door hanging plate 3 and the linkage assembly 4 from the influence of the external environment (such as dust, moisture, corrosives, etc.), extending the service life of the elevator door system. And it can effectively block dust and dirt from entering the interior of the elevator door system, reducing the workload of cleaning and maintenance.

[0051] In addition, noise will be generated when the active door hanging plate 2 and the passive door hanging plate 3 are opened and closed. Arranging the cover plate 6 can effectively isolate the noise from spreading through the air, reducing the interference of the noise to the surrounding environment and improving the riding experience.

[0052] In one embodiment, the cover plate 6 covers at least a part of the active door hanging plate 2, at least a part of the passive door hanging plate 3 and at least a part of the linkage assembly 4.

[0053] In one embodiment, the cover plate 6 is made of materials such as ordinary carbon steel plate, aluminum alloy plate, aluminum-magnesium alloy plate, stainless steel plate, etc., but is not limited thereto.

[0054] In one embodiment, the surface of the cover plate 6 is treated by surface treatment methods such as electrophoresis, spraying, etching, 3D printing, etc., but not limited thereto. The color of the cover plate 6 is coordinated or unified with the structures such as the active door hanging plate 2, the passive door hanging plate 3, and the hoistway frame to improve the aesthetics.

[0055] As Figure 1 shown, in one embodiment, the cover plate 6 and the bottom plate 1 are detachably connected through a connection structure 7. The connection structure 7 includes one or a combination of a plug-in connection structure, a snap connection structure, and a bolt connection structure. In this embodiment, by making the cover plate 6 and the bottom plate 1 detachably connected, when a certain component in the elevator door system fails or needs to be replaced, the detachable connection of the cover plate 6 and the bottom plate 1 allows maintenance personnel to quickly and conveniently disassemble and replace the faulty component, thus greatly reducing the downtime of the elevator door system and improving the production efficiency and equipment utilization rate.

[0056] In one embodiment, the connection structure 7 includes a bolt connection structure. The bolt connection structure includes a nut and a bolt. A first through hole is provided on the cover plate 6, and a second through hole is provided on the bottom plate 1. The bolt sequentially passes through the first through hole and the second through hole and is threadedly connected to the nut to fix the cover plate 6 and the bottom plate 1.

[0057] As Figures 1 - 4 shown, in one embodiment, the locking device 5 includes a first locking portion 51 and a second locking portion 52. The first locking portion 51 is provided on the active door hanging plate 2, and the second locking portion 52 is provided at the second end of the bottom plate 1.

The unlocking portion 513 protrudes from the cover plate 6 through the window 61. The unlocking portion 513 is used to separate the first locking portion 51 from the second locking portion 52 under the action of an external force to achieve the unlocking of the locking device 5.

[0059] In this embodiment, by providing the window 61 on the cover plate 6 to make the unlocking portion 513 protrude from the cover plate 6 through the window 61, it is convenient for an external force to directly act on the unlocking portion 513, improving the convenience of unlocking the locking device 5; at the same time, other components are covered by the cover plate 6 to prevent external forces from interfering with other components and affecting the normal operation of the elevator door system.

[0060] Specifically, the moving path of the unlocking portion 513 is exposed from the cover plate 6 through the window 61.

[0061] Specifically, the unlocking portion 513 includes a first ball and a second ball. Both the first ball and the second ball protrude from the cover plate 6 through the window 61. The first ball and the second ball are used to contact the car door knife and drive the first locking portion 51 under the drive of the car door knife, so that the first locking portion 51 is separated from the second locking portion 52 to achieve the unlocking of the locking device 5.

[0062] As Figures 1 - 4 shown, in one embodiment, the first locking portion 51 and / or the second locking portion 52 are exposed through the window 61 on the cover plate 6. This embodiment makes the first locking portion 51 and / or the second locking portion 52 clearly visible, facilitating maintenance personnel to observe the states of the first locking portion 51 and / or the second locking portion 52 during daily maintenance and inspection, and facilitating timely handling when the first locking portion 51 and / or the second locking portion 52 are abnormal or faulty, ensuring the safe operation of the elevator.

[0063] In one embodiment, the first locking portion 51 or the second locking portion 52 is exposed through the window 61 on the cover plate 6.

[0064] In one embodiment, both the first locking portion 51 and the second locking portion 52 are exposed through the window 61 on the cover plate 6.

[0065] As Figures 1 - 4 shown, in one embodiment, the ratio of the sum of the projected area of the cover plate 6 on the bottom plate 1 and the projected area of the window 61 on the bottom plate 1 to the area of the bottom plate 1 is between 80% - 100%. This embodiment increases the projected area of the cover plate 6 on the bottom plate 1, which can largely protect the components on the bottom plate 1 from external factors such as dust and dirt, ensuring good cleanliness of these components. At the same time, it can largely avoid accidental collisions from the outside to the components, effectively reducing the direct damage of external collisions to the internal components and extending the service life of the components.

[0066] In one embodiment, the ratio of the sum of the projected area of the cover plate 6 on the bottom plate 1 and the projected area of the window 61 on the bottom plate 1 to the area of the bottom plate 1 is 100%.

[0067] As Figures 1 - 4 shown, in one embodiment, the first locking portion 51 includes a locking hook 511. The locking hook 511 is rotatably arranged on the active door hanging plate 2. The unlocking portion 513 is arranged on the locking hook 511. The second locking portion 52 includes a locking hook plate 521. The locking hook 511 is engaged with the locking hook plate 521;

[0068] The first locking part 51 further includes a first conductive part 512 which is arranged on the locking hook 511. The second locking part 52 further includes a second conductive part 522 which is arranged on the locking hook plate 521. When the locking hook 511 is clamped with the locking hook plate 521, the first conductive part 512 contacts the second conductive part 522.

[0069] In this embodiment, a dual locking method of mechanical locking and electrical locking is provided. The mechanical locking provides direct safety protection through a physical locking mechanism; the electrical locking realizes more precise and reliable safety control through an electrical safety circuit and cooperation with the elevator control system, jointly escorting the safe operation of the elevator.

[0070] Specifically, the first conductive part 512 is a conductive contact, and the second conductive part 522 is a conductive switch. When the conductive contact contacts the conductive switch, the conductive switch is turned on.

[0071] As Figures 1 - 6 shown, in one embodiment, the guide rail 11 includes a first guiding part 111 and a second guiding part 112 arranged along the longitudinal direction.

[0072] In one embodiment, a first door hanging wheel 21 and a first limiting wheel 22 are arranged on the active door hanging plate 2. The first door hanging wheel 21 and the first limiting wheel 22 are arranged at intervals along the longitudinal direction. The guide rail 11 is located between the first door hanging wheel 21 and the first limiting wheel 22. The first door hanging wheel 21 is slidably connected with the first guiding part 111, and the first limiting wheel 22 is slidably connected with the second guiding part 112.

The second door hanging wheel 31 and the second limiting wheel 32 are arranged at intervals along the longitudinal direction. The guide rail 11 is located between the second door hanging wheel 31 and the second limiting wheel 32. The second door hanging wheel 31 is slidably connected with the first guiding part 111, and the second limiting wheel 32 is slidably connected with the second guiding part 112.

[0076] In this embodiment, in the longitudinal direction, the guide rail 11 is located between the second door hanging wheel 31 and the second limiting wheel 32 to limit the displacement of the passive door hanging plate 3 in the longitudinal direction, prevent the passive door hanging plate 3 from falling off the guide rail 11, and improve the safety of the elevator door system.

[0077] In one embodiment, the second door hanging wheel 31 and the guide rail 11 are mutually engaged to limit the displacement of the passive door hanging plate 3 in the lateral direction, further improving the safety of the elevator door system.

The first limiting member 23 is used to limit the lateral displacement of the active door hanging plate 2. In this embodiment, the longitudinal displacement and the lateral displacement of the active door hanging plate 2 are limited by the two first limiting members 23, further improving the stability of the elevator door system.

[0080] In one embodiment, two second limiting members 33 are provided on the passive door hanging plate 3, and the two second limiting members 33 are arranged at intervals in the longitudinal direction, and the guide rail 11 is located between the two second limiting members 33; one of the two second limiting members 33 contacts the side of the first guiding portion 111 away from the passive door hanging plate 3, and the other contacts the side of the second guiding portion 112 away from the passive door hanging plate 3. The second limiting member 33 is used to limit the lateral displacement of the passive door hanging plate 3. In this embodiment, the longitudinal displacement and the lateral displacement of the passive door hanging plate 3 are limited by the two second limiting members 33, further improving the stability of the elevator door system.

[0081] As Figures 1 - 4 shown, in one embodiment, the linkage assembly 4 includes a first fixing member 41, a second fixing member 44, a transmission rope 42 and two rope wheels 43. The two rope wheels 43 are arranged at intervals on the bottom plate 1. The first fixing member 41 and the second fixing member 42 are both located between the two rope wheels 43. The two ends of the transmission rope 42 are arranged on the first fixing member 41, and the transmission rope 42 sequentially passes through one of the two rope wheels 43, the second fixing member 44 and the other of the two rope wheels 43, so that the linkage assembly 4 forms a closed loop. The second fixing member 44 is used to lock the transmission rope 43;

[0082] Among them, both the active door hanging plate 2 and the passive door hanging plate 3 are located between two rope wheels 43, and one of the first fixing member 41 and the second fixing member 44 is arranged on the active door hanging plate 2, and the other is arranged on the passive door hanging plate 3.

[0083] In this embodiment, the active door hanging plate 2 and the passive door hanging plate 3 are linked by the transmission rope 42 to ensure that when one of them is not closed or not tightly closed, the other cannot be normally opened. This effectively prevents the elevator door from accidentally opening when it is not fully closed, thus avoiding the risk of passengers accidentally falling during the operation of the elevator.

[0084] In one embodiment, the first fixing member 41 is arranged on the passive door hanging plate 3, and the second fixing member 44 is arranged on the active door hanging plate 2. The second fixing member 44 is used to lock the transmission rope 43 so that the transmission rope 43 is stably connected to the active door hanging plate 2.

[0085] Specifically, the transmission rope 42 is a steel wire rope.

[0086] Specifically, a tensioning device is arranged on the transmission rope 42 to adjust the tension degree of the transmission rope 42.

[0087] As Figures 1 - 4 shown, in one embodiment, a self-closing device 8 is arranged between the passive door hanging plate 3 and the second end of the bottom plate 1. The self-closing device 8 includes an elastic member 81. One end of the elastic member 81 is arranged on the passive door hanging plate 3, and the other end is arranged on the second end of the bottom plate 1. The elastic member 81 is used to release elastic potential energy when the active door hanging plate 2 and the passive door hanging plate 3 are unlocked relative to the bottom plate 1, so as to drive the active door hanging plate 2 and the passive door hanging plate 3 to reset, so that the locking device 5 resumes the locked state, and the active door hanging plate 2 and the passive door hanging plate 3 resume the locked state relative to the bottom plate 1.
