[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] It should be noted that an elevator is a device used for vertical transportation, which is widely used in various buildings and provides convenience for people to move up and down stairs.

[0039] Elevator doors are an important component of elevators, mainly including landing doors located at the floor entrances and exits of the hoistway, and car doors located on the elevator car. The elevator car can move up and down along the vertical direction of the hoistway. During the elevator car's movement, the car doors and landing doors are closed to ensure the safety of personnel; when the elevator car stops, the car doors and the corresponding landing doors open to allow people to enter and exit.

[0040] Conventional elevator doors typically open and close by moving horizontally. Based on the number of doors on the same guide rail, elevator doors can be categorized into side-opening elevator doors and center-opening elevator doors. Side-opening elevator doors have only one door on the guide rail, and all doors move to the same side when opening and closing. Center-opening elevator doors have two doors on the guide rail, and the two doors on the same guide rail move in opposite directions when opening and closing.

[0041] Meanwhile, the number of doors varies depending on the type of elevator door. Most conventional elevator doors use a double-fold structure. Taking a center-parted double-fold elevator door as an example, it has a total of four doors. These four doors are divided into two groups of two. Of course, there are also multi-fold structures such as three-fold doors, side-opening elevator doors with a single door, and center-parting elevator doors with two doors.

[0042] The mounting plate is an important component of the elevator door. The door body is connected to the guide rail of the door head back panel through the mounting plate. During the opening and closing of the elevator door, the mounting plate is usually driven directly to move the door body.

[0043] Therefore, the structural strength of the mounting plate is crucial. One standard test requires the mounting plate to pass a door gap test, which involves applying a 150N force to the elevator door with it closed and checking the gap at the bottom of the door. The gap must not exceed 45mm. Whether the mounting plate meets the structural strength standard is one of the key factors in whether the elevator door can pass this test.

[0044] In existing technologies, a common way to increase the structural strength of the siding is to thicken it. While this method simply and effectively increases the structural strength of the siding, it also increases its weight and the difficulty of processing. This leads to many inconveniences for workers when transporting and installing elevator doors.

[0045] Another method is to increase the structural strength of the mounting plate by adding reinforcing ribs. However, as an important component of the elevator door, the mounting plate has many holes on its surface, which limits the placement of the reinforcing ribs and often makes it difficult to achieve an effective strengthening effect. Furthermore, the flatness of the mounting plate will be affected when processing the reinforcing ribs.

[0046] To address the aforementioned problems, embodiments of the present invention provide an elevator door device, including a support member 10 and a door connector 20.

[0047] Reference Figure 1 and Figure 2 As shown, the support member 10 is used to install the elevator door 50. The support member 10 can be installed on the elevator landing door or the elevator car door. When the support member 10 is installed on the elevator car door, it is fixedly connected to the elevator car. When the support member 10 is installed on the elevator landing door, it is fixedly connected to the wall of the floor. Preferably, the support member 10 is a door head back panel.

[0048] Reference Figure 3 and Figure 4 As shown, the door connector 20 is used to connect the load-bearing member 10 and the door body 50. Under the drive of the corresponding driver, it drives the door body 50 to move, thereby realizing the opening and closing of the door.

[0049] When the support member 10 is installed on the elevator car door, a door knife drive member is provided on the door connector 20. The door knife drive member is directly driven by a corresponding driver. During the elevator car's ascent and descent, the door knife drive member opens along the first direction D1 to allow the door ball drive member to pass. When the elevator car reaches its final position, the door knife drive member clamps the door ball drive member along the first direction D1, unlocking the door body 50 to allow the door body 50 to move and thus open the door.

[0050] When the load-bearing component 10 is installed on the elevator landing door, a door connecting component 20 is provided with a door ball drive component. The door ball drive component remains locked when the elevator car is not in position to prevent the landing door from opening. After the elevator car is in position, the door ball drive component is unlocked by the door knife drive component.

[0051] Along the first direction D1, the door connector 20 is configured to be movable relative to the carrier 10. Typically, a guide rail is provided on the carrier 10; the guide rail can be integrally formed with the carrier 10 or separate from it. The door connector 20 is connected to the guide rail, either slidably or by means of rollers.

[0052] Along the second direction D2, a first reinforcing part 21 and a second reinforcing part 22 are respectively provided on both sides of the door connector 20. The first reinforcing part 21 and the second reinforcing part 22 are used to increase the structural strength of the door connector 20.

[0053] Among them, the second direction D2 is parallel to the height direction of the target shaft, the first direction D1 is perpendicular to the second direction D2, and the third direction D3 is perpendicular to the first direction D1 and the second direction D2 respectively. The elevator shaft is usually a cuboid space. The depth direction of the elevator shaft is the direction from the inner wall of the hall door to the rear wall of the shaft. The depth direction of the elevator is perpendicular to the height direction and the width direction of the shaft respectively. The first direction D1 is preferably set as the width direction of the target shaft, and the third direction D3 is preferably set as the depth direction of the target shaft.

[0054] Those skilled in the art can set the shapes of the first reinforcing part 21 and the second reinforcing part 22 according to actual needs, such as structures like plate-shaped, hollow cylindrical, hollow triangular prism, hollow cuboid, etc.

[0055] Those skilled in the art can set the ways of connecting the first reinforcing part 21 and the second reinforcing part 22 to the door connecting member 20 according to actual needs. For example, the two reinforcing parts and the door connecting member 20 are integrally formed, or the separately arranged door connecting member 20 and the two reinforcing parts are fixedly connected by welding or other means. Preferably, the sheet material is folded by stamping to obtain the first reinforcing part 21 and the second reinforcing part 22.

[0056] Those skilled in the art can set the positions of the first reinforcing part 21 and the second reinforcing part 22 relative to the door connecting member 20 in the third direction D3 according to actual needs. For example, along the third direction D3, the first reinforcing part 21 and the second reinforcing part 22 are simultaneously arranged on the same side or different sides of the door connecting member 20. Preferably, the first reinforcing part 21 and the second reinforcing part 22 are simultaneously arranged on the same side of the door connecting member 20 along the third direction D3, so that the cross-sectional shape of the overall structure is a "匚"-shaped structure, which has a better effect of enhancing the structural strength.

[0057] In the case where the first reinforcing part 21 and the second reinforcing part 22 are arranged on the same side, the two reinforcing parts can be arranged on the side of the door connecting member 20 close to the bearing member 10, or can be arranged on the side away from the bearing member 10. Preferably. The two reinforcing parts are arranged on the side away from the bearing member 10, so as to install other components such as hanging wheels on the side of the door connecting member 20 close to the bearing member 10. And the space on the side of the door connecting member 20 away from the bearing member 10 is relatively sufficient, which will not affect the extension of the two reinforcing parts and will not affect the installation of other components, which is beneficial to improving the overall space utilization rate.

[0058] In this way, the structural strength of the door connecting member 20 can be improved without excessively increasing the weight and processing difficulty of the door connecting member 20.

[0059] Specifically, since the first reinforcing portion 21 and the second reinforcing portion 22 are respectively provided on both sides of the door connector 20 along the second direction D2, the cross-sectional shape of the door connector 20 can be changed, and this cross-section is perpendicular to the first direction D1. In the case where the two reinforcing portions are not provided, the cross-sectional shape of the door connector 20 is a rectangular structure, and this structure is particularly prone to torsion when subjected to torsion. After the first reinforcing portion 21 and the second reinforcing portion 22 are provided, the cross-sectional shape of the door connector 20 becomes a structure similar to a "U" shape. This shape allows more materials to be away from the cross-sectional neutral axis, effectively increasing the torsional moment of inertia, reducing the torsional stress inside the material under the action of the same torque, and thus strengthening the torsional resistance of the door connector 20 and improving the overall structural strength.

[0060] At the same time, in the case where the two reinforcing portions are not provided, a force application test is performed on the door body 50, and the edge portions on both sides of the door connector 20 along the second direction D2 are particularly prone to local bending and wrinkling, that is, local buckling. This local buckling will also affect the overall torsional strength and cause premature damage. After the first reinforcing portion 21 and the second reinforcing portion 22 are provided, the first reinforcing portion 21 and the second reinforcing portion 22 are equivalent to adding rigid supports to both sides of the door connector 20, which can effectively limit the occurrence of local buckling, avoid premature failure of the door connector 20, strengthen the torsional resistance of the door connector 20, and improve the overall structural strength.

[0061] It should be noted that in the prior art, there is also a structure in which a flanging is provided on one side of the hanging plate. However, this structure cannot effectively strengthen the structural strength, but instead makes the torsional performance of the non-flanged side of the hanging plate lower than that of the flanged side, and thus under the action of torque, the stress concentrates on the weaker non-flanged side, causing failure. In the present application, through the relatively symmetric first reinforcing portion 21 and the second reinforcing portion 22, this defect can be well avoided.

[0062] In summary, for the elevator door device described in the present invention, by respectively providing the first reinforcing portion 21 and the second reinforcing portion 22 on both sides of the door connector 20 along the second direction D2, the cross-sectional shape of the door connector 20 in the cross-section perpendicular to the first direction D1 is changed, making its cross-sectional shape similar to a "U" shape structure. This can effectively increase the torsional moment of inertia of the door connector 20, reduce the torsional stress. At the same time, the first reinforcing portion 21 and the second reinforcing portion 22 can inhibit the local buckling of the door connector 20, prevent the door connector 20 from failing prematurely, and thus strengthen the torsional resistance of the door connector 20, improve the overall structural strength, stability and safety. In addition, the lightweight requirement of the door connector 20 is also taken into account, without adding too much weight, which is convenient for the transportation and installation operations of the staff.

[0063] Refer to Figure 5 and Figure 6As shown, in some embodiments of the elevator door device of the present invention, a third reinforcing part 23 is provided on at least one side of the door connector 20 along the first direction D1. The third reinforcing part 23 connects the first reinforcing part 21, the second reinforcing part 22 and the door connector 20 respectively. Preferably, the door connector 20 is provided with the third reinforcing part 23 on both sides along the first direction D1.

[0064] Those skilled in the art can set the shape of the third reinforcing part 23 according to actual needs, such as plate-shaped, hollow cylindrical, hollow triangular, hollow cuboid and other structures.

[0065] Those skilled in the art can configure the connection method between the third reinforcing part 23 and the door connector 20 according to actual needs. For example, the third reinforcing part 23 and the door connector 20 can be integrally formed, or the separate door connector 20 and the third reinforcing part 23 can be fixedly connected by welding or other methods. Preferably, the third reinforcing part 23 is obtained by folding the sheet metal using a stamping process.

[0066] Those skilled in the art can position the third reinforcing part 23 relative to the door connector 20 in the third direction D3 according to actual needs. For example, along the third direction D3, the third reinforcing part 23 can be positioned on the side of the door connector 20 closer to the support member 10, or on the side away from the support member 10. Preferably, the third reinforcing part 23 and the other two reinforcing parts are positioned on the same side.

[0067] Based on the first reinforcing part 131 and the second reinforcing part 132, a third reinforcing part 23 is provided for the door connector 20, which can effectively achieve resistance to torsion, bending, and instability. Specifically, firstly, the three reinforcing parts can cooperate with each other to further optimize the torsional moment of inertia. Secondly, the third reinforcing part can enhance the bending resistance of the door connector 20 in the third direction D3, preventing the door connector 20 from bending and deforming; when combined with the first reinforcing part 131 and the second reinforcing part 132, it can effectively prevent the door connector 20 from undergoing out-of-plane deformation. Finally, the third reinforcing part can prevent local buckling of the side of the door connector 20 in the first direction D1, preventing the door connector 20 from failing prematurely.

[0068] Furthermore, in some embodiments of the elevator door device of the present invention, the first reinforcing part 21 is integrally formed with the door connector 20, the second reinforcing part 22 is integrally formed with the door connector 20, and the third reinforcing part 23 is integrally formed with the door connector 20. Preferably, the door connector 20 and each reinforcing part are processed by stamping, which is convenient for processing and has high structural strength.

[0069] Based on this, the first reinforcing part 21 and the second reinforcing part 22 are both integrally formed with the third reinforcing part 23, or the first reinforcing part 21 and the second reinforcing part 22 are both welded to the third reinforcing part 23.

[0070] Preferably, the first reinforcing part 21 and the second reinforcing part 22 are integrally formed with the third reinforcing part 23, so that the reinforcing part and the door connector 20 form a box-like structure, which effectively improves the overall structural strength.

[0071] Furthermore, refer to Figure 7 As shown, in some embodiments of the elevator door device of the present invention, the door connector 20 is further provided with a first connecting arc portion 24, which is disposed between the first reinforcing portion 21 and the third reinforcing portion 23, and the first connecting arc portion 24 connects the first reinforcing portion 21 and the third reinforcing portion 23 respectively. Or / and, the door connector 20 is further provided with a second connecting arc portion 25, which is disposed between the second reinforcing portion 22 and the third reinforcing portion 23, and the second connecting arc portion 25 connects the second reinforcing portion 22 and the third reinforcing portion 23 respectively. Thus, there are three possible configurations.

[0072] The first type has only the first connecting arc portion 24; the second type has only the second connecting arc portion 25; and the third type has both the first connecting arc portion 24 and the second connecting arc portion 25.

[0073] By incorporating connecting arcs, stress concentration at the joints of various reinforcing components can be effectively eliminated, preventing localized fracture failure. Under load, the force is evenly transferred along the arc surface of the connecting arc, preventing excessive accumulation at any single point. This effectively increases the structure's load-bearing capacity and fatigue life, enhancing the overall safety and reliability of the elevator.

[0074] Furthermore, refer to Figure 8 As shown, in some embodiments of the elevator door device of the present invention, the dimensions L1 of the first reinforcing part 21, the second reinforcing part 22 and the third reinforcing part 23 along the third direction D3 are set to be 3 to 5 times the dimensions L2 of the door connector 20.

[0075] The multiplier should not be too small. If the multiplier is too small, less than 3 times, the improvement in the torsional and bending moments of inertia of each reinforcement is limited, and deformation or local buckling is still likely to occur under torsion. Furthermore, it is not conducive to processing. The multiplier should not be too large. If the multiplier is too large, greater than 5 times, although structural strength can be guaranteed, the space utilization rate is relatively low. Setting the multiplier between 3 and 5 times can well balance strength, cost, and weight.

[0076] Those skilled in the art can set specific multipliers according to actual needs, such as 3 times, 3.1 times, 3.2 times, 3.3 times, 3.4 times, 3.5 times, 3.6 times, 3.7 times, 3.8 times, 3.9 times, 4 times, 4.1 times, 4.2 times, 4.3 times, 4.4 times, 4.5 times, 4.6 times, 4.7 times, 4.8 times, 4.9 times, 5 times, etc.

[0077] In elevator doors, besides the structural strength of the door connector 20, the structural strength of the load-bearing component 10 is equally important. To improve the structural strength of the load-bearing component 10, refer to... Figure 10 and Figure 11 As shown, in some embodiments of the elevator door device of the present invention, the support member 10 includes a support component 11, a guide rail component 12, and a guide rail reinforcing component 13.

[0078] The load-bearing component 11 is used to connect to the landing door wall or the elevator car. Preferably, the load-bearing component 11 includes a first load-bearing sub-component and a second load-bearing sub-component, with the second load-bearing sub-component positioned above the first load-bearing sub-component along a second direction D2. The width extension direction of the first load-bearing sub-component is parallel to the second direction D2, and the width extension direction of the second load-bearing sub-component is parallel to a third direction D3.

[0079] Along the second direction D2, the guide rail component 12 is disposed on one side of the support component 11. The guide rail component 12 includes a folding portion 121 and a guide portion 122 arranged sequentially along the third direction D3. The folding portion 121 is connected to the support component 11 and the guide portion 122 respectively. The guide portion 122 is used to cooperate with components such as hanging wheels to install the door connector 20, so that the door connector 20 can move relative to the support component 10 along the first direction D1.

[0080] Preferably, the width extension direction of the folded portion 121 is parallel to the third direction D3, and the width extension direction of the folded portion 121 is perpendicular to the width extension direction of the first bearing component. In a cross-section perpendicular to the first direction D1, the cross-sectional shape of the guide portion 122 is set to a convex arc shape.

[0081] Preferably, the load-bearing component 11 and the guide rail component 12 are integrally formed and are processed by folding.

[0082] When subjected to the force of the door connector 20, stress concentration is particularly prone to occur at the connection between the guide rail component 12 and the load-bearing component 11, affecting the overall structural strength and reliability. Therefore, a guide rail reinforcing component 13 is provided to thicken the structure, thereby increasing its strength.

[0083] Specifically, the guide rail reinforcing component 13 includes a first reinforcing part 131 and a second reinforcing part 132. Along the second direction D2, the first reinforcing part 131 is disposed on the side of the guide rail component 12 opposite to the supporting component 11. The first reinforcing part 131 connects to the guide part 122 and abuts against the folding part 121. Along the third direction D3, the second reinforcing part 132 is disposed on the side of the supporting component 11 opposite to the guide rail component 12, and the second reinforcing part 132 connects to both the first reinforcing part 131 and the supporting component 11.

[0084] In this way, the first load-bearing sub-component and the folding part 121 can be effectively thickened, thereby improving the overall structural strength and ensuring the high safety and reliability of the elevator.

[0085] Preferably, the guide rail reinforcing component 13 and the guide rail component 12 are integrally formed, and the load-bearing component 11, the guide rail component 12 and the guide rail reinforcing component 13 are obtained by folding.

[0086] The door connector 20 is provided with a first guide 27 and a second guide 28. The first guide 27 and the second guide 28 are arranged at intervals along a first direction D1. The first guide 27 is rolledly connected to the guide portion 122 along the first direction D1, and the second guide 28 is rolledly connected to the first reinforcing portion 131 along the first direction D1.

[0087] Preferably, both the first guide member 27 and the second guide member 28 are configured as pulleys. The first guide member 27 rolls on the guide rail, and the second guide member 28 assists in preventing the first guide member 27 from disengaging from the guide rail.

[0088] Furthermore, refer to Figure 12 As shown, in some embodiments of the elevator door device of the present invention, the first load-bearing component includes a first load-bearing body 111, a second load-bearing body 112, and a third load-bearing body 113. The first load-bearing body 111 is used to connect to the wall or the car.

[0089] Along the second direction D2, a second support 112 is disposed on one side of the first support 111, with one end of the second support 112 connected to one end of the first support 111. The width extension direction of the second support 112 forms an angle with the width extension direction of the first support 111. Along the second direction D2, a third support 113 is disposed on one side of the second support 112, with one end of the third support 113 connected to the other end of the second support 112. The width extension direction of the third support 113 is parallel to the width extension direction of the first support 111. Along the second direction D2, a guide rail component 12 is disposed on the side of the third support 113 opposite to the second support 112, and a folding portion 121 is connected to the third support 113. A second reinforcing portion 132 is disposed on the third support 113.

[0090] Thus, the first support 111, the second support 112, and the third support 113 form a step. Placing the second reinforcing part 132 in the space created by this step effectively improves the overall space utilization. Furthermore, when welding the second reinforcing part 132 to the first support component is required, welding can be performed at this location, concealing the weld point and ensuring an aesthetically pleasing overall appearance.

[0091] Furthermore, refer to Figure 12As shown, in some embodiments of the elevator door device of the present invention, the third support body 113 is provided with a first connecting hole 1131, and the second reinforcing part 132 is provided with a second connecting hole 1321 corresponding to the first connecting hole 1131. Locking members 30 are provided in the first connecting hole 1131 and the second connecting hole 1321. Alternatively, the second reinforcing part 132 is welded to the third support body 113.

[0092] Thus, there are three scenarios. First, fixation is achieved solely through locking element 30; second, fixation is achieved solely through welding; and third, fixation is achieved through both locking element 30 and welding. The third fixing method is preferred, as it effectively achieves a fixed connection, increasing overall stability and structural strength. Preferably, both connection holes are threaded holes, and locking element 30 is a bolt. Furthermore, the locking element 30 can also be used to directly connect to the wall and the car, further increasing overall stability and reliability.

[0093] Furthermore, refer to Figure 9 and Figure 10 As shown, in some embodiments of the elevator door device of the present invention, an anti-tipping component 40 is further included, which includes a first anti-tipping component 41 and a second anti-tipping component 42.

[0094] Along the third direction D3, a first anti-tipping component 41 is disposed between the door connector 20 and the support member 10, and the first anti-tipping component 41 is connected to the door connector 20. Along the third direction D3, a second anti-tipping component 42 is disposed on the side of the first anti-tipping component 41 away from the door connector 20, the second anti-tipping component 42 is connected to the first anti-tipping component 41, and the second anti-tipping component 42 is slidably connected to the guide portion 122 along the first direction D1. In some other embodiments, the second anti-tipping component 42 may also remain in contact with the guide portion 122 by default, or be spaced apart. Only when the door connector 20 is tilted relative to the support member 10, the second anti-tipping component 42 and the guide portion 122 cooperate to limit the door connector 20 from further tilting to the side away from the support member 10.

[0095] Preferably, the length extension direction of the first anti-rollover component 41 is parallel to the third direction D3. Preferably, the first anti-rollover component 41, the second anti-rollover component 42, and the door connector 20 are integrally formed, and the first anti-rollover component 41 and the second anti-rollover component 42 are obtained by stamping and folding.

[0096] The first anti-rollover component 41 is configured such that its dimension along the first direction D1 gradually decreases in the direction away from the door connector 20. This reduces the size of the first anti-rollover component 41, improving overall space utilization.

[0097] Reference Figure 2 and Figure 3As shown, in some embodiments of the elevator door device of the present invention, a second reinforcing part 22 is provided on the side of the door connector 20 away from the support member 10 along the third direction D3. The second reinforcing part 22 is provided with a first door connecting part 26. The elevator door device also includes a door body 50, on one side of the door body 50 along the second direction D2, a second door connecting part 51 is provided, and the second door connecting part 51 is connected to the first door connecting part 26.

[0098] Preferably, the first door connecting part 26 is configured as a mounting hole, and the second door connecting part 51 includes bolts and nuts to achieve the connection and assembly of the door body 50 and the door connector 20, facilitating disassembly and maintenance. In some other embodiments, the connection between the two can also be achieved by welding, snap-fitting, or other methods.

[0099] To ensure the stability and safety of the elevator car during operation, the car can only move up or down after the car door and landing door are in position and switched to the closed state. The position detection of the car door and landing door is usually achieved by a contact switch. However, in existing technology, the installation position of the contact switch is not ideal. This not only wastes installation space but also allows dust to easily enter the contact base, leading to switch failure. Furthermore, the switch is prone to arcing during engagement, causing it to fail or be damaged prematurely.

[0100] To solve the above problems, refer to Figure 13 and Figure 14 As shown, in some embodiments of the elevator door device of the present invention, a contact seat 60 is further included. The contact seat 60 includes a first contact seat 61 and a second contact seat 62.

[0101] The first contact 61 is disposed on the support member 10, and has two contact holes 611 arranged at intervals along the third direction D3 to cooperate with the movement of the door connector 20 to achieve positioning detection. The second contact 62 is disposed on the door connector 20, and has contact pins 621 corresponding to the two contact holes 611.

[0102] When the contact pin 621 is inserted into the contact socket 611, it indicates that the corresponding door body 50 is in position. The principle of the position detection of the contact device 60 is prior art and will not be described in detail. In some other embodiments, the second contact 62 can also be connected to the ball drive or door knife drive.

[0103] By setting this structure, the insertion holes, which were originally spaced apart along the height of the shaft, are now spaced apart along a third direction (D3). This effectively reduces the possibility of dust and foreign objects entering the contact insertion holes 611, preventing the contactor 60 from failing. Simultaneously, the two contact pins 621 can be inserted into their respective contact insertion holes 611 at the same time, ensuring high synchronization of engagement and accuracy of the engagement angle. This avoids arcing during sequential insertion, which could burn the pins and contact seat, thus ensuring the contactor 60 functions well and extending its service life—achieving multiple benefits in one fell swoop.

[0104] On the other hand, embodiments of the present invention also provide an elevator, including the elevator door device as described in any of the above embodiments. Since the elevator of the present invention includes the elevator door device described in the above embodiments, it also possesses all the beneficial effects described herein, and will not be repeated here.

[0105] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0106] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0107] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
