[0049] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0050] It should be noted that an elevator is a device used for vertical transportation. It is widely used in various buildings and provides convenience for people to move up and down the stairs.

[0051] Elevator doors are a crucial component of an elevator. They primarily consist of landing doors at the entrances and exits of the hoistway floors, and car doors on the elevator car. The car can rise and fall along the height of the hoistway. While the elevator car is in motion, the car door and landing doors are closed to ensure passenger safety. When the elevator car stops, the car door and corresponding landing doors open to allow passengers to enter and exit.

[0052] Conventional elevator doors typically open and close horizontally. Depending on the number of doors on a single track, elevator doors can be categorized as side-opening or center-opening. Side-opening doors have only one door on their track, and when opening and closing, both doors move in the same direction. Center-opening doors have two doors on their track, and when opening and closing, the two doors on the same track move in opposite directions.

[0053] The number of door bodies varies between different elevator doors. Conventional elevator doors mostly use a bi-fold structure. For example, a center-split bi-fold elevator door has four doors in total. These four doors are divided into two groups of two. Of course, there are also multi-fold structures such as tri-fold, side-opening elevator doors with a single door, and center-split elevator doors with two doors.

[0054] In order to ensure the stability of the door when it moves, a guide rail 01 is usually set to provide guidance for the movement of the door. Figure 1 As shown, Figure 1 The figure shows a conventional elevator door structure. The door body of the prior art is not shown in the figure. The door body is slidably connected to the guide rail 01 through the hanging plate 02.

[0055] The hanging plate 02 generally includes two surfaces, wherein the surface adjacent to the corresponding guide rail 01 is the first surface, and the surface opposite to the first surface is the second surface. The first surface is provided with a hanging wheel 03, which realizes reciprocating sliding on the guide rail 01 through the hanging wheel 03.

[0056] Typically, each hanging plate 02 is provided with four hanging wheels 03, which are divided into two groups of two. The hanging wheels 03 in one group are relatively large in diameter and are located above the guide rail 01; the hanging plates 02 in the other group are relatively small in diameter and are located below the guide rail 01.

[0057] Elevators typically use car doors as active doors and landing doors as driven doors. This means a motor and corresponding transmission structure are installed in the elevator car, which drives the car door along the guide rail 01. Synchronous linkage structures are also installed on the car door and landing door bodies to ensure that the landing door opens and closes synchronously with the car door.

[0058] For example, in a bifold elevator, a door blade assembly 04 is typically installed on the car door panel 02 corresponding to the elevator's rapid guide rail 01, and a linkage ball is installed on the corresponding landing door panel 02. When the elevator car is in position, the door blades of the door blade assembly 04 clamp the linkage ball, driving the motor to move the car door and, simultaneously, the landing door.

[0059] In the prior art, the synchronous linkage structures between the car and landing doors, such as the door knife and linkage ball, are usually installed on the second surface. That is, these structures and the hanging pulley 03 are respectively installed on two different surfaces of the hanging plate 02. As a result, the synchronous linkage structure, hanging plate 02, and hanging pulley 03 each occupy a certain amount of space in the depth direction of the elevator shaft, which is bulky and has low space utilization.

[0060] The elevator shaft is usually a rectangular space. The depth direction of the elevator shaft is from the inner wall of the hall door to the rear wall of the shaft. The elevator depth direction is perpendicular to the height direction and the width direction of the shaft.

[0061] For example, conventional elevator door systems can measure 100mm to 150mm in the hoistway depth. This makes it difficult to install large devices within the limited hoistway space. Furthermore, these large devices are difficult to transport and handle.

[0062] To solve the above problems, refer to Figure 2 As shown, an embodiment of the present invention provides an elevator door device, including a bearing member 10, a guide member 20 and a door connecting member 30.

[0063] The bearing member 10 is used to securely mount the guide member 20. In some embodiments, the bearing member 10 can be mounted on an elevator car to provide guidance for the car door via the guide member 20. In some embodiments, the bearing member 10 can be mounted on a wall at the entrance or exit of an elevator shaft to provide guidance for a landing door via the guide member 20. How to securely mount the bearing member 10 on an elevator car or wall is well known in the art and will not be further described.

[0064] Those skilled in the art can set the shape and material of the carrier 10 according to actual needs to ensure that the carrier 10 can maintain a stable and firm connection.

[0065] Preferably, the carrier 10 is set as a door head back plate. Figure 5 As shown, the carrier includes a first carrier 11 , a second carrier 12 and a third carrier 13 .

[0066] The first carrier 11 is disposed on one side of the guide member 20 along the first direction D1. The second carrier 12 is disposed on one side of the guide member 20 along the second direction D2 and is connected to the first carrier 11. Two third carriers 13 are provided, one on each side of the guide member 20 along the third direction D3, and both third carriers 13 are connected to the first carrier 11.

[0067] Preferably, the first direction D1 is parallel to the depth direction of the elevator shaft, the second direction D2 is parallel to the height direction of the shaft, and the third direction D3 is parallel to the width direction of the shaft. It can be understood that the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0068] When the elevator door device is installed on the car, a synchronous drive motor 111 can be installed on the first carrier 11. The driving end of the synchronous drive motor 111 is connected to the synchronous drive belt 112. The driving end of the synchronous drive motor 111 drives the synchronous drive belt 112 to rotate clockwise or counterclockwise, thereby driving the car door hanging plate connected to the synchronous drive belt 112 to move, thereby realizing the opening and closing of the car door. Preferably, the driving end of the synchronous drive motor 111 is parallel to the first direction D1.

[0069] By adopting this structure, compared with setting the floor doors as active doors, only one synchronous drive motor 111 is required on the car to drive the doors on each floor, and there is no need to install a motor on each floor door. This saves the space required for installation, reduces the volume, improves the overall space utilization, and effectively saves the cost of multiple motors.

[0070] The guide member 20 is used to mount the door connector 30, through which the corresponding door body 70 is mounted. After the door connector 30 is mounted on the guide member 20, the door connector 30 can move relative to the guide member 20, and the guide member 20 provides guidance for the movement of the door connector 30. The same guide member 20 can provide guidance for only one door connector 30, or it can provide guidance for both door connectors 30 at the same time.

[0071] Those skilled in the art can set a specific guide member 20 structure according to actual needs to adapt to different door connectors 30 and door bodies 70. Preferably, the guide member 20 is set to be hollow along its length direction to reduce weight while increasing strength and improving bending resistance.

[0072] Those skilled in the art can adjust the number of guide members 20 according to actual needs, such as one, two, three, four, or five, to accommodate the installation and guidance requirements of different numbers of door connectors 30. Preferably, only two guide members 20 are provided, i.e., the elevator is configured as a side-opening bi-folding structure or a center-split bi-folding structure.

[0073] The guide member 20 is disposed on one side of the first carrier 11 along the first direction D1. If multiple guide members 20 are provided, the guide members 20 are sequentially arranged along the first direction D1. Those skilled in the art can adjust the relative positions of the guide members 20 according to actual needs. For example, the positions of the guide members 20 can be kept consistent in the second direction D2, or one or more guide members 20 can be staggered relative to the other guide members 20.

[0074] Preferably, the length extension direction of each guide member 20 is set to be parallel to the third direction D3. In some embodiments, the length extension direction of one or more guide members 20 can also have a certain angle relative to other guide members 20, as long as the angle does not affect the movement of the door body 70.

[0075] The guide member 20 is connected to the carrier 10. Different elevator door systems utilize different connection methods for the guide member 20 and the carrier 10. For example, the guide member 20 can be connected to the corresponding third carrier 13 at both ends along the third direction D3. Alternatively, multiple connecting members, such as bolts, can be sequentially provided on the guide member 20 at intervals along the third direction D3 to connect the guide member 20 to the first carrier 11.

[0076] The door connector 30 is movably connected to the guide member 20. Preferably, a connecting pulley 35 is provided on the door connector 30, and the door connector 30 is slidably connected to the guide member 20 via the connecting pulley 35.

[0077] Preferably, each door connector 30 is provided with four connecting pulleys 35, which are arranged at the four corners of a quadrilateral, preferably a rectangle or an isosceles trapezoid. The four connecting pulleys 35 are divided into two groups, each with two connecting pulleys. One group of connecting pulleys 35 is arranged on one side of the guide member 20 along the second direction D2, with its wheel surface abutting the upper portion of the guide member 20; the other two connecting pulleys 35 are arranged on the other side of the guide member 20 along the second direction D2, with their wheel surfaces abutting the lower portion of the guide member 20.

[0078] On this basis, the door connector 30 can reciprocate relative to the guide member 20 along the third direction D3. Taking a bifold door elevator as an example, when the elevator doors need to be closed, the door connectors 30 move along the third direction D3, so that the corresponding door bodies 70 remain offset, achieving the door closing and switching to the closed state. Conversely, the door bodies 70 remain overlapped, achieving the door opening and switching to the open state.

[0079] On the door connecting member 30 , in addition to the connecting pulley 35 , a target functional member 34 is often required to be provided. The target functional member 34 includes a door blade driver 40 , a door ball driver and a driven synchronizer 90 .

[0080] For example, a door blade actuator 40 is typically installed on the door connector 30 of the shutter corresponding to the car door, and a door ball actuator is typically installed on the door connector 30 of the shutter corresponding to the landing door. The shutter refers to the door body 70 mounted on the fast guide rail, and its travel distance is the longest among all the door bodies 70. When the elevator doors are opened and closed, the travel distances of the door bodies 70 vary, but they must open and close synchronously. Consequently, the door bodies 70 on the fast guide rails move relatively quickly.

[0081] In order to reduce the volume and improve space utilization, the position of the door connector 30 relative to the guide member 20 and the position of the target functional member 34 relative to the door connector 30 need to be adjusted. Specifically, the door connector 30 includes a first door connector 301 and / or a second door connector 302.

[0082] Reference Figure 2 and Figure 3 As shown, the first guide member 201 is the guide member 20 at the beginning of the first direction D1. When there is only one guide member 20, the only guide member 20 is the first guide member 201; when there are multiple guide members 20, the first guide member 201 is the guide member 20 closest to the first carrier 11 among the guide members 20.

[0083] Along the first direction D1, the first door connector 301 is disposed between the first guide member 201 and the first carrier 11. The first door connector 301 is movably connected to the first guide member 201. A first connection surface 3011 of the first door connector 301 is the surface where the first door connector 301 connects to the first guide member 201. Specifically, the corresponding connecting pulley 35 of the first door connector 301 is disposed on the first connection surface 3011. The first connection surface 3011 is used to accommodate at least one target functional component 34, preferably, only one target functional component 34.

[0084] For example, when the elevator door is set to a structure such as a side-opening type or a center-opening type with only one guide member 20, the first door connecting member 301 connecting the car door body can be provided with a door knife actuator 40 on the first connecting surface 3011; the first door connecting member 301 connecting the floor door body can be provided with a door ball actuator on the first connecting surface 3011.

[0085] When the elevator door is configured as a side-opening double-folding door with multiple guide members 20 structures, the door body 70 connected to the first door connector 301 is no longer a shutter. Accordingly, a driven synchronizer 90 can be provided on the first connecting surface 3011 to realize the synchronous linkage switching of the first door connector 301 and other door connectors 30.

[0086] With this structure, both the target functional component 34 and the connecting pulley 35 are located on the first connecting surface 3011 of the first door connector 301, rather than being located on either side of the hanging plate as in the prior art. This effectively reduces the device's volume in the elevator shaft depth direction, improving space utilization and making it well suited for use in limited hoistway spaces. The reduced device size facilitates transportation and installation, improving operational efficiency.

[0087] It is worth noting that, along the first direction D1, a certain gap should be provided between the first door connecting member 301 and the first carrier 11 to avoid problems such as scratching between the two.

[0088] Reference Figure 2 and Figure 4 As shown, along the first direction D1 , the second door connecting member 302 is disposed between two adjacent guide members 20 .

[0089] The second guide member 202 is the guide member 20 that is relatively far away from the first guide member 201 along the first direction D1 among the two guide members 20 adjacent to the second door connecting member 302. It can be understood that at least two guide members 20 are provided in the device corresponding to the second guide member 202.

[0090] The second door connector 302 is movably connected to the second guide member 202. The second connecting surface 3021 is the surface where the second door connector 302 connects to the second guide member 202. In other words, the corresponding connecting pulley 35 of the second door connector 302 is disposed on the second connecting surface 3021. The second connecting surface 3021 of the second door connector 302 is used to mount at least one target functional component 34, preferably, only one target functional component 34.

[0091] The target functional component 34 on the second connecting surface 3021 of the second door connector 302 may also vary depending on the second guide member 202. For example, a side-opening tri-fold elevator door includes three guide members 20: a fast guide rail, a medium-speed guide rail, and a slow guide rail. The slow guide rail is the guide member 20 closest to the first carrier 11. The second door connector 302 can be positioned between the fast and medium-speed guide rails and slidably connected to the fast guide rail via a connecting pulley 35. Alternatively, the second door connector 302 can be positioned between the medium-speed guide rail and the slow guide rail and slidably connected to the medium-speed guide rail via a connecting pulley 35.

[0092] When the second door connector 302 is arranged on the fast guide rail, the second door connector 302 connected to the car door body can be provided with a door knife actuator 40 on the second connecting surface 3021; the second door connector 302 connected to the floor door body can be provided with a door ball actuator on the second connecting surface 3021.

[0093] When the door body 70 connected to the second door connector 302 is no longer a shutter door body, a driven synchronizer 90 can be provided on the second connecting surface 3021 to cooperate with the door connector 30 connected to the shutter door body to achieve synchronous door opening and closing.

[0094] It can be understood that the entire device adjusts at least one door connecting member 30 on the guide member 20, which can achieve the effect of reducing the volume and improving space utilization.

[0095] Still taking the side-opening tri-fold elevator door as an example, only the first door connector 301 can be set. In this case, the first door connector 301 is set between the slow guide rail and the first carrier 11, and the other door connectors 30 can be adaptively set; only the second door connector 302 can be set. The second door connector 302 is set between the fast guide rail and the medium-speed guide rail, or between the medium-speed guide rail and the slow guide rail, and the other door connectors 30 can be adaptively set.

[0096] Preferably, the first door connector 301 and the second door connector 302 are provided simultaneously to achieve the best effect. According to actual measurements, the size of the elevator door device in the first direction D1 according to the embodiment of the present invention can be reduced to one-half to one-third of the conventional size.

[0097] It is worth noting that no matter what the structure of the target functional part 34 is, when installing it on the corresponding connecting surface, care should be taken to avoid other components to avoid affecting its use. For example, the door knife transmission 40 or the door ball transmission can be set between the four connecting pulleys 35 along the third direction D3.

[0098] In summary, the elevator door device of the present invention addresses the issues of conventional elevator doors' bulk and low space utilization in the hoistway depth direction by adjusting the relative positions of the door connector 30, target functional component 34, and guide member 20. By positioning the corresponding target functional component 34 on the connecting surface between the door connector 30 and the guide member 20, the space on this surface is fully utilized, reducing the device's volume in the hoistway depth direction and improving its space utilization. Actual measurements have shown that the device can be reduced to one-half to one-third of its conventional size. This effectively reduces the difficulty of device installation and transportation.

[0099] When the device is applied to an elevator car to open and close the elevator door, a door knife actuator 40 is usually required to achieve synchronous opening and closing of the elevator door and landing door. Since the relative positions of the door connector 30 and the guide member 20, as well as the relative positions of the door knife actuator 40 and the corresponding door connector 30, have been adjusted, the structure of the door knife actuator 40 also needs to be adjusted.

[0100] Reference Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments of the elevator door device of the present invention, the door knife actuator 40 is disposed on the third connecting surface 3031 of the third door connecting member 303. The third door connecting member 303 is movably connected to the third guide member 203. The third connecting surface 3031 is the surface where the third door connecting member 303 connects to the third guide member 203, that is, the corresponding connecting pulley 35 of the third door connecting member 303 is disposed on the third connecting surface 3031.

[0101] The third guide member 203 is the guide member 20 at the end of the first direction D1. It is understood that, depending on the number of guide members 20 in the device, the third guide member 203 can be either the first guide member 201 or the second guide member 202. Accordingly, the third door connector 303 can be either the first door connector 301 or the second door connector 302.

[0102] For example, when the elevator door is set to a side-opening type, a center-opening type, etc. and is only provided with one guide member 20, the only guide member 20 is at both the beginning and the end of the first direction D1.

[0103] When the elevator door is configured as a side-opening double-folding door with multiple guide members 20, the third guide member 203 is the guide member 20 farthest from the first carrier 11 along the first direction D1 among the guide members 20, so as to be close to the floor door to realize transmission.

[0104] The door knife transmission device 40 is arranged on the third connection surface 3031. Along the third direction D3, the four connecting pulleys 35 on the third connection surface 3031 are divided into two groups. Preferably, the door knife transmission device 40 is arranged between the two groups of connecting pulleys 35 to improve structural stability.

[0105] The door knife transmission device 40 includes a door knife connecting rod 41 and a door knife arm 42. The door knife arm 42 is a main component for the door knife transmission device 40 to realize transmission with the corresponding door ball transmission device, and is connected to the third connecting surface 3031 through the door knife connecting rod 41.

[0106] Preferably, two door knife links 41 and two door knife arms 42 are provided. Along the second direction D2, the two door knife links 41 are disposed on either side of the third guide member 203, and both door knife links 41 are rotatably connected to the third connecting surface 3031. Along the third direction D3, the two door knife arms 42 are disposed on either side of the rotating axis of the door knife link 41, and each door knife arm 42 is rotatably connected to both door knife links 41. With this structure, the two door knife links 41 and the two door knife arms 42 form a parallelogram-like structure, enabling the door knife actuator 40 to switch operating states while maintaining good stability.

[0107] It should be noted that, along the first direction D1, the third guide member 203 is disposed between the door blade arm 42 and the third door connecting member 303. The spacing between the various components along the first direction D1 should be appropriately set to avoid interference during operation. For example, along the first direction D1, the third guide member 203 is configured to be smaller than the dimension between the door blade arm 42 and the third door connecting member 303.

[0108] The door blade actuator 40 operates in two states: open and clamped. For example, consider a parallelogram. The centers of two opposing sides are fixed, and the sides are connected in a rotational manner. By moving one of the other two sides relative to the other, the distance between them can be adjusted.

[0109] When the door knife actuator 40 is in an open state, the dimension between the two door knife arms 42 along the third direction D3 is a first dimension. When the door knife actuator 40 is in a clamped state, the dimension between the two door knife arms 42 along the third direction D3 is a second dimension C2, which is smaller than the first dimension. Figure 12 The second dimension C2 is shown in FIG.

[0110] When the door knife transmission device 40 is in the open state, the door knife arm 42 is separated from the corresponding door ball, and the car door and the landing door are both in the closed state. At this time, the car where the door knife transmission device 40 is located can move along the second direction D2, thereby transporting the passengers in the car to the corresponding floors.

[0111] When the door knife transmission device 40 is in the clamping state, the door knife arm 42 clamps the corresponding door ball. At this moment, it is possible to cooperate with the door ball to realize transmission so that the corresponding floor door can realize switching together with the car door.

[0112] Preferably, in actual use, the state switching of the above components is achieved by the synchronous drive motor 111 cooperating with the synchronous drive belt 112.

[0113] For example, a synchronous drive motor 111 is provided on a first carrier 11 connected to the elevator car. A synchronous drive wheel is provided on the driving end of the synchronous drive motor 111. Meanwhile, another synchronous drive wheel is provided on one side of the synchronous drive motor 111 along the third direction D3. The synchronous drive wheel is rotationally connected to the first carrier 11. A synchronous drive belt 112 is sleeved on the two synchronous drive wheels.

[0114] In the case of a side-opening elevator door, only one door knife actuator 40 is provided on the car, and one door knife arm 42 is connected to the synchronous drive belt 112. The driving end of the synchronous drive motor 111 rotates, driving the synchronous drive belt 112 to rotate, thereby switching the door knife actuator 40 between an open state and a clamped state.

[0115] In the case of a center-split elevator door, at least one door blade actuator 40 is installed on the car. When only one door blade actuator 40 is provided, the two third door connectors 303 on the third guide member 203 can achieve synchronized state switching by providing an additional synchronous linkage mechanism. When two door blade actuators 40 are provided, each door blade actuator 40 has a door blade arm 42 connected to the synchronous drive belt 112 to ensure that the door connectors 30 and the door body 70 can move relatively close to or away from each other.

[0116] When the door blade actuator 40 is not switched to the clamped state, the car door and the corresponding landing door remain closed. When the door blade actuator 40 is switched to the clamped state, the car door can switch between the closed and open states. Correspondingly, the landing door can also switch between states under the drive of the door blade arm 42.

[0117] In the prior art, conventional connecting rods and hanging plates, as well as blade arms and connecting rods, are generally connected by bearings for rotation, which are relatively large and have low space utilization.

[0118] In order to solve the above problems, further referring to Figure 6As shown, in some embodiments, the door knife link 41 is rotatably connected to the third connecting surface 3031 via a connecting rod bearing 411. The door knife link 41 and the door knife arm 42 are rotatably connected via a connecting rod pin 412. This structure can further reduce the volume of the device along the third direction D3, improving space utilization. Preferably, the axial directions of the connecting rod bearing 411 and the connecting rod pin 412 are parallel to the first direction D1.

[0119] To ensure the stability and safety of the elevator car during operation, a door lock is usually installed on the car door. The door lock can prevent the car door from opening accidentally. When the car stops at the corresponding floor, the door can only be opened after the door lock is unlocked.

[0120] However, in the prior art, there are defects in the structure of the car door lock, which results in a large volume in the depth direction of the shaft and low space utilization. Specifically, the car door lock usually needs to be linked with the knife arm. When the knife arm is relatively close, the locked car door lock rotates to open. The existing car door lock is usually set in the middle of the knife arm along the height direction of the shaft. It can be imagined that in order to avoid mutual interference among the various components, the knife arm, door lock, hanging plate and guide rail need to maintain a certain dislocation along the depth direction of the shaft. At the same time, in order to smoothly realize the transmission coordination between the knife arm and the door lock, complex transmission components need to be set between the two, and the transmission components will also occupy a certain volume.

[0121] To solve the above problems, refer to Figure 6 As shown, the elevator door device of the present invention, in some embodiments, further includes a first locker 50, which is used to lock the car door. The first locker 50 is arranged on one side of the third door connector 303 along the second direction D2. Preferably, the first locker 50 is arranged between the third door connector 303 and the second carrier 12.

[0122] By adjusting the position of the first locker 50 relative to the door blade actuator 40, the positional relationship between the two is changed from being arranged sequentially along the depth direction of the shaft as in the prior art to being staggered along the second direction D2. On this basis, the ample space in the shaft height direction can be fully utilized to save space in the shaft depth direction, effectively improving space utilization.

[0123] When the position is adjusted, the connection relationship between the components also needs to be adjusted accordingly to ensure that the door blade transmission device 40 and the first locking device 50 can work stably. Figure 8 and Figure 9 As shown, in some embodiments, the first locker 50 includes a first locking seat 51 , a locking transmission member 52 , a first locking member 53 and a locking lifting hook member 54 .

[0124] The first locking seat 51 is connected to the third door connecting member 303. Preferably, the two are connected by fastening components such as bolts and nuts.

[0125] The locking transmission member 52 is movably connected to the first locking seat 51. Preferably, the first locking seat 51 is provided with two parallel guide rods, whose axes are parallel to the third direction D3. The locking transmission member 52 is slidably connected to the guide rods via linear bearings, thereby enabling movement relative to the first locking seat 51 along the third direction D3. Linear bearings effectively reduce friction and ensure smooth movement of all components. They also make motion transmission more direct and efficient, with fast transmission feedback response.

[0126] In actual use, the locking transmission member 52 is connected to the synchronous drive belt 112 through a synchronous belt clamp. When the synchronous drive belt 112 rotates, the locking transmission member 52 can move along the third direction D3.

[0127] Preferably, refer to Figure 9 As shown, the first locking seat 51 is provided with limit adjustment screw holes 511 at both ends along the third direction D3. Each limit adjustment screw hole 511 is provided with a limit adjustment bolt 512, and the two are threadedly connected. When the locking transmission member 52 is in contact with the limit adjustment bolt 512, the locking transmission member 52 cannot move further toward the side where the corresponding limit adjustment bolt 512 is located. This structure allows the movable range of the locking transmission member 52 to be adjusted by rotating the limit adjustment bolt 512, which is very convenient.

[0128] Next, a first transmission part 521 is provided on the locking transmission member 52, and a second transmission part 421 is provided on a door knife arm 42. The second transmission part 421 can move along the second direction D2 relative to the first transmission part 521, and the second transmission part 421 can rotate relative to the first transmission part 521.

[0129] Those skilled in the art can configure two transmission components based on actual needs. Preferably, the first transmission component 521 is configured as a transmission through hole, the opening of which is rectangular, with the length of the rectangle parallel to the second direction D2. The second transmission component 421 is configured as a transmission pin, which moves or rotates within the transmission through hole. Preferably, the axial direction of the transmission pin is parallel to the first direction D1.

[0130] The first locking member 53 is rotatably connected to the first locking seat 51. Preferably, the first locking member 53 is rotatably connected to the first locking seat 51 via a bearing, the axial direction of the bearing being parallel to the first direction D1. The first locking member 53 is provided with a first locking hook portion 531 and a first lifting hook abutment portion 532. The first locking hook portion 531 is configured to engage with the first target locking portion 5311.

[0131] Preferably, the first target locking portion 5311 is fixedly mounted on the carrier 10, or on another third door connector 303, so that when the car door is in position and closed, the car door is then locked by the first lock hook portion 531 and the first target locking portion 5311. Preferably, the first lifting hook abutting portion 532 is configured as an abutting pin, the axial direction of which is parallel to the first direction D1; the first lock hook portion 531 is configured as a lock hook, and the first target locking portion 5311 is configured as a locking block.

[0132] The locking hook 54 is rotated to connect the locking transmission member 52, referring to Figure 9 As shown, preferably, the locking hook member 54 is rotatably connected to the locking transmission member 52 via a hook shaft 543 , and the axial direction of the hook shaft 543 is parallel to the first direction D1 . The locking hook member 54 is provided with a third transmission portion 541 and a second hook abutting portion 542 .

[0133] The second transmission part 421 is movable relative to the third transmission part 541 along the second direction D2, and the second transmission part 421 is rotatable relative to the third transmission part 541. Preferably, the third transmission part 541 is also configured as a transmission through hole, and the opening of the transmission through hole is rectangular, with the length of the rectangle parallel to the second direction D2.

[0134] The second lifting hook abutting portion 542 is in contact with the first lifting hook abutting portion 532. It is understood that the two are relatively movable. Preferably, the second lifting hook abutting portion 542 is configured as an abutting surface.

[0135] The working states of the first locker 50 include a first locked state and a first unlocked state. When the first locker 50 is in the first locked state, the first lock hook portion 531 is locked with the first target locking portion 5311. When the first locker 50 is in the first unlocked state, the first lock hook portion 531 is unlocked with the first target locking portion 5311.

[0136] In the process of switching the state of the first lock 50, it is necessary to cooperate with the door knife arm 42. Specifically, taking the first lock 50 switching from the first locking state to the first unlocking state as an example:

[0137] First, refer to Figure 6 and Figure 9 As shown, the locking transmission member 52 is driven by the synchronous drive motor 111 to move relative to the first locking seat 51. Since the locking transmission member 52 and the door blade arm 42 are connected via the first transmission portion 521 and the second transmission portion 421, the door blade actuator 40 also switches state from the original open state to the clamped state during the movement of the locking transmission member 52.

[0138] Secondly, refer to Figure 7 and Figure 10As shown, the locking transmission member 52 is initially moved into position, so that the door blade transmission device 40 is switched from the open state to the clamped state.

[0139] Then, refer to Figure 11 and Figure 12 As shown, since the dimension between the door blade arms 42 has reached the second dimension, it cannot be further reduced. At this time, if the locking transmission member 52 continues to move, the locking hook member 54 will rotate relative to the locking transmission member 52. It can be understood that in the process of rotating relative to the locking transmission member 52, the locking hook member 54 also rotates relative to the door blade arms 42. When the locking hook member 54 rotates, the second hook abutting portion 542 applies a force to the first hook abutting portion 532, causing the first locking member 53 to rotate relative to the first locking seat 51, thereby unlocking the first locking hook portion 531 and the first target locking portion 5311.

[0140] Finally, the locking transmission member 52 moves into position and abuts against one of the limit adjustment bolts 512 on the first locking seat 51, completely unlocking the first lock hook portion 531 and the first target locking portion 5311. On this basis, the first locker 50, the door blade transmission 40, and the third door connector 303 all move along the third direction D3 driven by the synchronous drive motor 111, thereby switching the states of the car door and the landing door and realizing door opening.

[0141] By providing the first locking device 50 with this structure, firstly, stable and reliable transmission can be achieved between the various components. Secondly, the overall structure is compact and small in size, effectively saving the volume required in the second direction D2 and achieving high space utilization. Finally, by providing an improved transmission structure between the locking transmission member 52, the first locking member 53, the locking hook member 54, and the door blade arm 42, the travel required for the locking transmission member 52 to move is shorter when the first locking device 50 is in the switching state, compared to conventional car door locks. This helps to reduce the volume of the device in the third direction D3 and further improve space utilization.

[0142] Preferably, the first locking member 53 is further provided with a first locking limiting hole 533 to cooperate with the limiting component on the first locking seat 51 to limit the rotation angle range of the first locking member 53 .

[0143] When designing an elevator, safety is a key consideration. Since the elevator requires electrical drive when in use, when the power is off, the door body 70 that has lost its electrical drive is difficult to open, posing a potential safety hazard.

[0144] In order to solve the above problems, further referring to Figure 8As shown, in some embodiments of the elevator door device of the present invention, the first locker 50 further includes a first elastic member 55, which is respectively connected to the first locking seat 51 and the locking transmission member 52. The first elastic member 55 is used to drive the locking transmission member 52 to move relative to the first locking seat 51, thereby switching the first locker 50 from the first locked state to the first unlocked state.

[0145] Preferably, the first elastic member 55 is configured as a spring, which is sleeved on the guide rod of the first locking seat 51 .

[0146] When the car is in place but the car door is closed and cannot be opened due to a power outage, the first elastic member 55 can simulate the synchronous drive motor 111 to provide an elastic driving force for the locking transmission member 52. On this basis, rescuers or trapped people can more easily unlock the first lock 50, greatly improving the safety of the device.

[0147] At the same time, compared with conventional devices in the prior art, by setting the first elastic member 55 and cooperating with the structure of the improved first locker 50, the interval between the first lock hook portion 531 and the first target locking portion 5311 along the third direction D3 in the first unlocked state can be effectively reduced, thereby reducing the volume of the device in the third direction D3 and improving space utilization.

[0148] In the prior art, due to the limited structure of the door blade and the car door lock, the car door lock often requires a relatively long travel of the actuator (the component connecting the door blade and the timing belt) to unlock. To prevent direct contact between the first lock hook 531 and the first target lock portion 5311 during the transition from the open to the clamped state, which could prevent them from separating and unlocking, a relatively large gap of approximately 23 mm is typically maintained between the first lock hook 531 and the first target lock portion 5311 when the car door is closed.

[0149] When the first elastic member 55 is provided, in conjunction with the first locking device 50, the travel distance required for the locking transmission member 52 can be effectively shortened, thereby unlocking the first locking member 53. Furthermore, in the first unlocked state, the distance between the first locking hook portion 531 and the first target locking portion 5311 along the third direction D3 can also be reduced from the conventional 23 mm to approximately 5 mm.

[0150] Further, refer to Figure 14As shown, in some embodiments of the elevator door device according to the present invention, the first locking member 53 is further provided with a plurality of adjustment strip holes 534. The plurality of adjustment strip holes 534 are sequentially arranged along the second direction D2, and the extension direction of each adjustment strip hole 534 is parallel to the third direction D3. An adjustment connector 535 is disposed within each adjustment strip hole 534. The adjustment connector 535 can be moved along the adjustment strip hole 534 and then fixed. Preferably, the adjustment connector 535 is configured as a combination of a bolt and a nut.

[0151] The first locker 50 further includes a door locking adjustment component 58, which is connected to the adjustment connector 535. The door locking adjustment component 58 is provided with a third lock hook portion 581, which is used to cooperate with the first target locking portion 5311. Preferably, the third lock hook portion 581 is configured as a lock hook.

[0152] By providing this structure, the distance between the first locking hook portion 531 and the first target locking portion 5311 along the third direction D3 in the first unlocked state can be flexibly adjusted.

[0153] Generally speaking, the spacing between the first lock hook portion 531 and the first target locking portion 5311 along the third direction D3 is 5 mm. When the door locking adjustment component 58 is set, the relative positions of the door locking adjustment component 58 and the first locking member 53 can be adjusted, so that the third lock hook portion 581 can replace the first lock hook portion 531 to achieve cooperation with the first target locking portion 5311.

[0154] On this basis, in the first unlocked state, the spacing between the second lock hook portion 621 and the first target locking portion 5311 along the third direction D3 can be flexibly adjusted within 5 mm, thereby improving the reliability and safety of the first locker 50.

[0155] Considering that the structure of the first locking device 50 effectively reduces the volume, the locking transmission member 52 will move during the process of switching the car door from the open state to the closed state, causing the first locking member 53 to rotate and reset in advance, affecting the normal closing of the car door. Figure 11 and Figure 12 As shown, in some embodiments of the elevator door device of the present invention, a first unlocking abutment portion 522 is provided on the locking transmission member 52. The first locker 50 further includes a locking and unlocking member 56 and a second elastic member 57.

[0156] The locking and unlocking member 56 is rotatably connected to the first locking seat 51. Preferably, the two are rotatably connected by a pin, the axial direction of the pin being parallel to the first direction D1. The locking and unlocking member 56 is provided with a second unlocking abutment 561 and a third unlocking abutment 562. The second unlocking abutment 561 is configured to cooperate with the target unlocking portion 5611.

[0157] Preferably, the target unlocking portion 5611 is fixedly mounted on the carrier 10, and only when the third door connector 303 is moved into position and the car door is switched to the closed state does the second unlocking abutment portion 561 abut against the target unlocking portion 5611. Preferably, the first unlocking abutment portion 522 is configured as an abutment groove, the second unlocking abutment portion 561 is configured as an abutment block, the target unlocking portion 5611 is configured as a combination of a threaded hole and a screw, and the third unlocking abutment portion 562 is configured as an abutment ball.

[0158] The locking and unlocking member 56 operates in two states: a limited state and a circumventing state. When the locking and unlocking member 56 is in the limited state, the second unlocking abutment portion 561 is separated from the target unlocking portion 5611, and the third unlocking abutment portion 562 abuts against the first unlocking abutment portion 522. At this point, the locking transmission member 52 is constrained by the locking and unlocking member 56 and cannot move in the opposite direction, thereby maintaining the first lock 50 in the first unlocked state when the car door is not closed.

[0159] When the locking and unlocking member 56 is in the avoidance state, the second unlocking abutment portion 561 abuts against the target unlocking portion 5611, and the third unlocking abutment portion 562 is separated from the first unlocking abutment portion 522. At this time, the car door has switched to the closed state, and the first locker 50 can switch between the first locked state and the first unlocked state.

[0160] The second elastic member 57 is respectively connected to the first locking seat 51 and the locking and unlocking member 56. The second elastic member 57 is used to drive the locking and unlocking member 56 to rotate, so that the locking and unlocking member 56 switches from the avoidance state to the limit state. Preferably, the second elastic member 57 is configured as a torsion spring.

[0161] When the second unlocking abutment 561 abuts against the target unlocking portion 5611 , the locking unlocking member 56 overcomes the elastic force of the second elastic member 57 and rotates relative to the first locking seat 51 , thereby separating the third unlocking abutment 562 from the first unlocking abutment 522 .

[0162] On the contrary, when the second unlocking abutment 561 is separated from the target unlocking portion 5611, the force of the target unlocking portion 5611 is lost, and the locking unlocking member 56 rotates in the opposite direction relative to the first locking seat 51 under the elastic force of the second elastic member 57, so that the third unlocking abutment 562 abuts against the first unlocking abutment 522, preventing the first locking member 53 from rotating.

[0163] This structure is compact and can effectively prevent the first locking member 53 from resetting prematurely, thereby ensuring that the first locking device 50 works safely, stably and reliably.

[0164] When the device is used on a hoistway floor to open and close a landing door, a door-ball actuator is typically required to cooperate with the blade arm to achieve synchronized opening and closing of the car door and landing door. Since the relative positions of the door connector 30 and the guide member 20, as well as the relative positions of the door-ball actuator and the corresponding door connector 30, have been adjusted, the structure of the door-ball actuator also needs to be adjusted.

[0165] Reference Figure 15 and Figure 16 As shown, in some embodiments of the elevator door device of the present invention, the door ball actuator is disposed on the fourth connecting surface 3041 of the fourth door connecting member 304. The fourth door connecting member 304 is movably connected to the fourth guide member 204. The fourth connecting surface 3041 is the surface where the fourth door connecting member 304 connects to the fourth guide member 204. In other words, the corresponding connecting pulley 35 of the fourth door connecting member 304 is disposed on the fourth connecting surface 3041.

[0166] The fourth guide member 204 is the guide member 20 at the end of the first direction D1. It will be understood that the fourth guide member 204 is provided at the entrance and exit of the hoistway floor, and is distinct from the third guide member 203. It will be understood that, depending on the number of guide members 20 in the device, the fourth guide member 204 can be either the first guide member 201 or the second guide member 202. Accordingly, the fourth door connector 304 can be either the first door connector 301 or the second door connector 302.

[0167] For example, when the elevator door is set to a side-opening type, a center-opening type, etc. and is only provided with one guide member 20, the only guide member 20 is at both the beginning and the end of the first direction D1.

[0168] When the elevator door is configured as a side-opening bi-folding door with multiple guide members 20, the fourth guide member 204 is the guide member 20 farthest from the first carrier 11 along the first direction D1 among the guide members 20, so as to be close to the car door to realize transmission.

[0169] The door ball actuator includes a linkage door ball 61 , which is used to cooperate with a target knife arm. Preferably, the target knife arm is the door knife arm 42 of the door knife actuator 40 .

[0170] The linkage ball 61 is rotatably connected to the fourth connection surface 3041. Preferably, the two are rotatably connected via a bearing, the axial direction of the bearing being parallel to the first direction D1. In any direction perpendicular to the first direction D1, the size of the linkage ball 61 is set to the second size to match the door knife arm 42.

[0171] Along the third direction D3, the four connecting pulleys 35 on the fourth connecting surface 3041 are divided into two groups. Preferably, the linkage door ball 61 is arranged between the two groups of connecting pulleys 35 to improve structural stability.

[0172] Preferably, the gate ball transmission device further comprises a second locking member 62. The second locking member 62 is connected to the gate ball 61, and is provided with a second locking hook portion 621 and a third lifting hook abutting portion 622.

[0173] The second locking hook portion 621 is used to cooperate with the second target locking portion 6211. Preferably, the second locking hook portion 621 is configured as a locking hook, and the second target locking portion 6211 is configured as a locking block.

[0174] Preferably, the second target locking portion 6211 is fixedly provided on the carrier 10 , or provided on another fourth door connecting member 304 , so that the floor door is closed when in place, and then locked by the second locking hook portion 621 and the second target locking portion 6211 .

[0175] When the elevator door is a side-opening type, that is, two fourth door connecting members 304 are provided on the fourth guide member 204, a linkage door ball 61 is provided on the fourth connecting surface 3041 of each fourth door connecting member 304, and only one of the linkage door balls 61 is provided with a second locking member 62, while the fourth door connecting member 304 corresponding to the other linkage door ball 61 is provided with a second target locking part 6211.

[0176] The third lifting hook abutment portion 622 is used to cooperate with the target knife arm. Preferably, the third lifting hook abutment portion 622 is configured as an abutment ball, which is rotatably connected to the second locking member 62, and its rotation axis is parallel to the first direction D1; the target knife arm is the door knife arm 42 of the door knife actuator 40.

[0177] Preferably, a second locking limiting hole 623 is further provided on the second locking member 62 to cooperate with the limiting component on the fourth door connecting member 304 to limit the rotation angle range of the second locking member 62 .

[0178] The operating states of the door ball actuator include a second locked state and a second unlocked state. When the door ball actuator is in the second locked state, the target knife arm is separated from the third lifting hook abutment portion 622. Due to the loss of the force of the target door knife, the second locking member 62 rotates and resets under the action of gravity, so that the second locking hook portion 621 is locked with the second target locking portion 6211.

[0179] When the door ball actuator is in the second unlocking state, the target blade arm abuts against the third lifting hook abutting portion 622, providing a force to the second locking member 62 through the target blade arm, causing the second locking member 62 to rotate relative to the fourth door connecting member 304, thereby separating the second locking hook portion 621 from the second target locking portion 6211, thereby achieving unlocking. At this time, the door bodies 70 of each floor door can move synchronously with the car door under the drive of the synchronous drive motor 111, achieving state switching.

[0180] Reference Figure 17 and Figure 18 As shown, in some embodiments of the elevator door device of the present invention, the elevator door device further comprises a door body 70 and a door fastener 73. The door connector 30 comprises a first connector 31, a second connector 32 and a third connector 33.

[0181] The connecting pulley 35 and the target functional component 34 are both arranged on the first connecting body 31 .

[0182] Along the second direction D2, the second connector 32 is disposed on one side of the first connector 31. Preferably, along the second direction D2, the second connector 32 and the second carrier 12 are disposed on either side of the first connector 31. One end of the second connector 32 is connected to one end of the first connector 31. An angle is formed between the extension direction of the second connector 32 and the extension direction of the first connector 31 to facilitate avoidance, thereby reducing the volume of the door connector 30 in the first direction D1 and improving space utilization. Those skilled in the art can adjust the angle based on actual needs, and this will not be described in detail here.

[0183] Along the second direction D2, the third connector 33 is disposed on one side of the second connector 32. As will be appreciated, along the second direction D2, the first connector 31 and the third connector 33 are respectively disposed on either side of the second connector 32. One end of the third connector 33 is connected to the other end of the second connector 32, and the extension direction of the third connector 33 is parallel to the extension direction of the first connector 31. A first connection hole 331 is provided on the third connector 33.

[0184] The door body 70 is provided with a receiving portion 71 and a connecting portion 72 at one end thereof along the second direction D2. The receiving portion 71 and the connecting portion 72 are arranged sequentially along the first direction D1. Preferably, the receiving portion 71 is configured as a receiving cavity, the third connecting body 33 is disposed within the receiving portion 71, and the connecting portion 72 is provided with a second connecting hole 721 corresponding to the first connecting hole 331. Door fasteners 73 connect the first connecting hole 331 and the second connecting hole 721, respectively. Preferably, the door fasteners 73 are configured as bolts.

[0185] This structure effectively reduces the space required for the connection structure between the door body 70 and the door connector 30 in the first direction D1, while facilitating assembly and disassembly, thereby reducing the device size and improving space utilization. Furthermore, by adjusting the positions of the target functional component 34, the door connector 30, and the guide member 20, the device as a whole can be made more compact.

[0186] To ensure the stability and safety of the elevator car during operation, the car door and landing door must be in place and closed before the car can be raised or lowered. This is typically detected by a contact switch. However, in existing technology, the contact switch is not properly installed. This not only wastes installation space but also makes it easy for dust to enter the contact seat, causing the contact switch to fail. Furthermore, arc erosion is easily generated when the switch is engaged, causing the switch to fail or prematurely damage.

[0187] To solve the above problems, refer to Figure 19 As shown, the elevator door device of the present invention, in some embodiments, further includes a seat contactor 80, which is disposed on one side of the door connector 30 along the second direction D2. The seat contactor 80 includes a first contactor 81 and a second contactor 82.

[0188] The first contact base 81 is fixedly connected to the carrier 10. Preferably, the first contact base 81 is fixedly mounted on the second carrier 10. Two contact base receptacles 811 are provided on one side of the first contact base 81 along the third direction D3 to facilitate movement of the door connector 30 and detect the door's position. The two contact base receptacles 811 are spaced apart along the first direction D1.

[0189] The second contact base 82 is connected to the door connector 30 and is provided with two contact pins 821 corresponding to the two contact sockets 811. When the contact pins 821 are inserted into the contact sockets 811, the corresponding door body 70 is in place. The principle of detecting the position of the contact base 80 is prior art and will not be further described. In some other embodiments, the second contact base 82 can also be connected to the first locking member 53 or the second locking member 62.

[0190] This structure shifts the jacks, originally spaced sequentially along the shaft height, to spaced sequentially along the first direction D1. This effectively reduces the size of the contactor 80 in the second direction D2. This, combined with the positional adjustments between the target functional component 34, the door connector 30, and the guide member 20, makes the overall device more compact.

[0191] Secondly, the elevator shaft environment is relatively harsh, and a certain amount of dust foreign matter is arranged. By arranging this structure, the possibility that dust foreign matter enters the contact seat jack 811 can be effectively reduced, preventing the contact seat device 80 from losing effectiveness.

[0192] Finally, the two contact pins 821 can be inserted into the corresponding contact sockets 811 at the same time, ensuring the synchronization of engagement and the accuracy of the engagement angle, avoiding the generation of arcs and burning of pins and contact sockets when inserting and engaging one after another, thereby ensuring that the contact socket 80 can work well, extending its service life, and achieving multiple goals at one stroke.

[0193] In the case where a plurality of guide members 20 are provided, a driven synchronizer 90 needs to be provided between each door connecting member 30 to ensure that a synchronous switching state can be achieved.

[0194] Reference Figure 5 、 Figure 16 and Figure 20 As shown, in some embodiments of the elevator door device of the present invention, the driven synchronizer 90 is disposed on the fifth connecting surface 3051 of the fifth door connecting member 305. The fifth door connecting member 305 is movably connected to the fifth guide member 205. The fifth connecting surface 3051 is the surface where the fifth door connecting member 305 connects to the fifth guide member 205, that is, the connecting pulley 35 corresponding to the fifth door connecting member 305 is disposed on the fifth connecting surface 3051.

[0195] The fifth guide member 205 is any guide member 20 other than the guide member 20 at the end in the first direction D1. It is understood that, depending on the number of guide members 20 in the device, the fifth guide member 205 can be either the first guide member 201 or the second guide member 202. Accordingly, the fifth door connector 305 can be either the first door connector 301 or the second door connector 302.

[0196] The driven synchronizer 90 includes a driven synchronous belt 92 and two driven synchronous pulleys 91. Both driven synchronous pulleys 91 are rotatably connected to the corresponding fifth door connector 305. Preferably, the axis of the two driven synchronous pulleys 91 is parallel to the first direction D1. Along the third direction D3, the two driven synchronous pulleys 91 are spaced apart. The driven synchronous belt 92 is mounted on the two driven synchronous pulleys 91 and includes a first belt portion 921 and a second belt portion 922. Along the second direction D2, the first belt portion 921 and the second belt portion 922 are respectively disposed on either side of the driven synchronous pulley 91.

[0197] The first belt portion 921 is connected to the carrier 10, and the second belt portion 922 is connected to the sixth door connector 306. The sixth door connector 306 is a door connector 30 adjacent to the fifth door connector 305 and relatively far away from the first guide member 201 along the first direction D1.

[0198] By setting up this structure, when the elevator door is opened or closed, different door connecting members 30 can realize synchronous movement under the action of the synchronous drive motor 111 and the corresponding transmission components.

[0199] Of course, in some other embodiments, door connectors 30 are provided on both sides of the fifth door connector 305 along the first direction D1. In this case, the first belt portion 921 can also connect to a seventh door connector. The seventh door connector is the door connector 30 that is relatively close to the first guide member 201 along the first direction D1, of the two door connectors 30 adjacent to the fifth door connector 305. The seventh door connector is not shown in the figure.

[0200] In the case of a center-split elevator door, the number of door bodies 70 and door connectors 30 is relatively large. In order to ensure that each component can operate synchronously, a complex linkage structure is often required in the prior art. In order to simplify the device structure, avoid the increased risk of failure caused by complex linkage structure switching, and improve the reliability of the device, refer to Figure 5 As shown, in some embodiments of the elevator door device of the present invention, each guide member 20 is provided with two door connecting members 30 , the moving directions of the two door connecting members 30 are opposite, and each door connecting member 30 is provided with a target functional member 34 .

[0201] Taking the third and fourth door connectors 303 and 304 as an example, two third door connectors 303 are provided on the third guide member 203, and a door blade actuator 40 is provided on the third connection surface 3031 of each third door connector 303. Two fourth door connectors 304 are provided on the fourth guide member 204, and a door ball actuator is provided on the fourth connection surface 3041 of each fourth door connector 304. The door ball actuators correspond to the door blade actuators 40 in a one-to-one manner and cooperate with each other to achieve synchronous movement of each door connector 30 under the control of the synchronous drive motor 111.

[0202] When the elevator door is bi-folded, tri-folded or more folded, the device further includes a fifth door connector 305 in addition to the third door connector 303 and the fourth door connector 304. In this case, each fifth door connector 305 is provided with a driven synchronizer 90.

[0203] This structure, compared to the complex linkage structures used in the prior art, utilizes a dual door blade and door ball mechanism for the door connector 30 of the center-split elevator door, thereby synchronously driving the movement of the two door bodies 70. Furthermore, by directly providing a driven synchronizer 90 on the other door connector 30, the conventional sheave support structure is eliminated, making the drive more direct and reliable. This effectively addresses the problem of the prior art, which relies on a single door blade and door ball mechanism in conjunction with a complex linkage structure, resulting in complex structures and prone to failure. It effectively ensures smooth and stable operation of the device, while also reducing the device size to a certain extent and improving space utilization.

[0204] On the other hand, an embodiment of the present invention further provides an elevator, comprising the elevator door device described in any one of the above embodiments. Since the elevator of the present invention comprises the elevator door device described in the above embodiments, the elevator also has all the beneficial effects, which will not be described in detail.

[0205] The elevator door system can be used for both car doors and hall doors. Depending on the number of door connectors 30 on the same guide member 20, the elevator can have a side-opening door or a center-opening door. Depending on the number of guide members 20, the elevator can have single-folding, bi-folding, or tri-folding doors.

[0206] Working principle:

[0207] Taking a center-split double-fold elevator as an example, after the car moves into position, driven by the synchronous drive motor 111, the locking transmission member 52 moves along the third direction D3, and the door knife actuator 40 switches from the original open state to the clamped state.

[0208] When the locking transmission member 52 is initially moved into place, the door knife transmission device 40 switches to the clamping state and clamps the linkage door ball 61. At this time, the corresponding second locking member 62 of the floor door is switched to the second unlocking state by the action of the door knife arm 42.

[0209] The locking transmission member 52 continues to move. At this time, since the size between the door knife arm 42 is already the second size and cannot be further reduced, the locking lifting hook member 54 rotates relative to the locking transmission member 52 and the door knife arm 42, and the second lifting hook abutment portion 542 applies a force to the first lifting hook abutment portion 532, causing the first locking member 53 to rotate relative to the first locking seat 51, thereby switching the first lock 50 from the first locking state to the first unlocking state.

[0210] The locking transmission member 52 moves into position and abuts against one of the limit adjustment bolts 512 on the first locking seat 51, completely unlocking the first lock hook portion 531 and the first target locking portion 5311. On this basis, each door connecting member 30 is driven by the synchronous drive motor 111 to move along the third direction D3, thereby switching the states of the car door and the landing door and realizing door opening.

[0211] As the door connectors 30 move, the second unlocking abutment 561 of the locking and unlocking member 56 separates from the target unlocking portion 5611. Without the force of the target unlocking portion 5611, the locking and unlocking member 56 rotates relative to the first locking seat 51 under the elastic force of the second elastic member 57, causing the third unlocking abutment 562 to abut against the first unlocking abutment 522, thereby preventing the first locking member 53 from rotating and returning to its original position.

[0212] After the people of the car and floor have finished entering and exiting, each door connecting member 30 is reset and closed under the drive of the synchronous drive motor 111. In the process of closing the door, the third unlocking abutting portion 562 abuts against the first unlocking abutting portion 522, preventing the first locking member 53 from rotating and resetting in advance.

[0213] After each door connector 30 is fully closed, the contact pin 821 inserts into the corresponding contact socket 811, the second unlocking abutment 561 abuts the target unlocking portion 5611, and the locking and unlocking member 56 overcomes the elastic force of the second elastic member 57 and rotates relative to the first locking seat 51, thereby separating the third unlocking abutment 562 from the first unlocking abutment 522. At this time, as the locking transmission member 52 moves, the door blade actuator 40 switches to the open state, the first locking member 53 switches to the first locking state, and the second locking member 62 switches to the second locking state. Afterwards, the elevator car can move accordingly.
