Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an elevator door assembly and an elevator system. Background Art

[0002] Elevators are essential facilities in high-rise buildings. Elevators enable users to reach the corresponding floor quickly in a shorter time, thus saving users time and energy.

[0003] In the related art, a sill is provided under the entrance and exit of a box elevator to fill the gap between the elevator shaft and the ground to prevent users or objects from falling into the elevator shaft from the gap. At the same time, a guide groove is provided on the top surface of the sill to cooperate with the elevator door to guide the elevator door during its sliding process.

[0004] However, debris easily accumulates in the guide grooves of the sill, causing the elevator door to jam or even malfunction. To avoid this problem, some manufacturers have proposed a solution with no top grooves. In this solution, guide grooves are located on the sides of the sill. While this solution solves the problem of debris easily accumulating in the guide grooves, it is difficult to apply to elevator systems with multiple landing doors. Summary of the Invention

[0005] The present application provides an elevator door assembly and an elevator system, aiming to improve the problem that debris easily accumulates in the guide groove of the sill, and the elevator door assembly is suitable for an elevator system with multiple landing doors.

[0006] The specific technical solutions are as follows: One embodiment of the present application provides an elevator door assembly, which includes a sill, a shutter, and a slow door. The sill extends along a first direction, and is formed with a first guide groove. The first guide groove extends along the first direction. The first guide groove is arranged on the side of the sill and opens downward. The shutter is installed with a first guide member, which cooperates with the first guide groove. The bottom of the slow door is provided with a second guide groove, which extends along the first direction. The top surface of the sill is provided with a second guide member, which cooperates with the second guide member. The shutter and the slow door are also connected by a guide assembly.

[0007] The elevator door assembly in the embodiment of the present application has a first guide groove formed on the sill. The first guide groove is arranged on the side of the sill and opens downward. Compared with the method of setting the guide groove on the top surface of the sill in the related art, the first guide groove located on the side of the sill and opening downward is not easy to accumulate debris, thereby reducing the risk of problems such as jamming and malfunction of the elevator door.

[0008] On this basis, the shutter is equipped with a first guide member, which cooperates with the first guide groove. During the process of opening or closing the shutter, the first guide member moves along the first guide groove, thereby preventing the shutter from shifting during the movement. A second guide member is provided on the top surface of the sill, and a second guide groove is provided on the bottom of the slow door. The second guide groove cooperates with the second guide member. During the process of opening or closing the slow door, relative movement occurs between the second guide groove and the second guide member, thereby preventing the slow door from shifting during the movement. It can be seen that the above-mentioned setting method enables both the shutter and the slow door to obtain a good guiding effect during the movement, that is, the elevator door assembly in this application is suitable for elevator systems with multiple floor doors.

[0009] In addition, the shutter and slow shutter are connected by a guide assembly. For the slow shutter, the guide assembly provides a mating connection point for the slow shutter, and the second guide also provides a mating connection point for the slow shutter. This can reduce the number of second guides required. For example, one or two second guides can be used to mate with a slow shutter, and the second guides are located in positions that can cover the slow shutter in both the open and closed states. This arrangement not only improves the stability of the slow shutter's movement, but also prevents the second guide from being exposed when the slow shutter is fully open, thereby preventing the user from tripping or stepping on the second guide and injuring themselves.

[0010] In some embodiments, the shutter is equipped with two first guide members, the two first guide members are arranged at intervals along the first direction, the second guide groove of the shutter cooperates with one second guide member, the two second guide members are arranged at intervals along the first direction, and the distance between the two second guide members is less than or equal to 1 / 10 of the distance between the two first guide members.

[0011] The shutter is equipped with two first guide members, which are spaced apart along a first direction. The two first guide members have a significant spacing along the first direction, and both first guide members cooperate with the first guide groove on the sill, thereby improving the movement stability of the shutter during opening or closing. The second guide groove of the slow shutter cooperates with the two second guide members. In other words, there are two second guide members that cooperate with one slow shutter, and the spacing between the two second guide members is significantly smaller than the spacing between the two first guide members. In this way, the two second guide members are relatively close and can be located near the door frame. Therefore, when the slow shutter is fully open, the second guide members can be prevented from being exposed to the outside, thereby preventing the user from tripping or stepping on the second guide members and being injured.

[0012] In some embodiments, the guide assembly includes a third guide groove, a first connecting frame and a third guide member, the third guide groove is arranged on the slow shutter, the third guide groove extends along the first direction, one end of the first connecting frame is connected to the shutter, the third guide member is connected to the other end of the first connecting frame, and the third guide member cooperates with the third guide groove.

[0013] During movement of the shutter relative to the slow shutter, the shutter drives the third guide member via the first connecting frame to move relative to the slow shutter, causing the third guide member to move along the third guide groove. Since the third guide member is always within the third guide groove, the third guide member and the third guide groove always maintain a mating relationship. Thus, even if the number of second guide members is reduced, for example, only one second guide member is required to mate with each slow shutter, the stability of the slow shutter's movement during opening and closing can be ensured.

[0014] In some embodiments, the first connecting frame is connected to a side wall of the shutter at one end along the first direction.

[0015] The first connecting frame is arranged on the side wall of one end of the shutter along the first direction (the end of the shutter along the first direction close to the slow door when the elevator door is in the closed state), which can ensure that no matter what position the shutter moves to, the third guide member and the third guide groove can always maintain a matching relationship, thereby ensuring that the slow door can always obtain good movement stability.

[0016] In some embodiments, the opening of the third guide groove is arranged upward, the opening of the second guide groove is arranged downward, and the second guide groove is located directly below the third guide groove.

[0017] With this arrangement, while ensuring that the third guide member cooperates with the third guide groove and the second guide member cooperates with the second guide groove, the third guide groove and the second guide groove are arranged in the up and down directions. This is beneficial to reducing the size of the slow door in its own thickness direction and avoiding the slow door being designed to be too thick.

[0018] In some embodiments, the third guide groove and the second guide groove are an integrated structure, which can save manufacturing steps and reduce costs during processing.

[0019] In some embodiments, the first guide member is connected to a side of the shutter away from the slow shutter along a second direction through a second connecting frame, and the second direction is perpendicular to the first direction.

[0020] One end of the second connecting frame is connected to the shutter, and the other end is connected to the first guide member. The provision of the second connecting frame maintains a stable relative positional relationship between the first guide member and the shutter, thereby enabling the first guide member to effectively guide the shutter. In addition, the shutter is typically positioned on the inner side of the slow door, that is, the shutter is closer to the elevator car than the slow door. The second connecting frame is connected to the side of the shutter facing away from the slow door along the second direction, which places the second connecting frame on the inner side of the shutter. In this way, the second connecting frame is not visible to users from outside the elevator car, thereby facilitating the external aesthetics of the elevator door assembly.

[0021] In some embodiments, the number of the shutters is one or two, the number of the slow shutters is one or two, and the number of the shutters and the number of the slow shutters are equal. In other words, the elevator door assembly in the embodiments of the present application is applicable to both side-opening elevator doors and bi-folding elevator doors.

[0022] Another embodiment of the present application provides an elevator door assembly, which includes a sill, a shutter, a slow door and a middle door, the sill extending along a first direction, the sill forming a first guide groove, the first guide groove extending along the first direction, the first guide groove being arranged on the side of the sill and opening downward; a first guide member is installed at the lower part of the shutter, the first guide member cooperates with the first guide groove; a second guide groove is provided at the bottom of the slow door, the second guide groove extends along the first direction, a second guide member is provided on the top surface of the sill, the second guide groove cooperates with the second guide member; along the second direction, the middle door is located between the shutter and the slow door, the second direction being perpendicular to the first direction; wherein the shutter and the middle door, as well as the middle door and the slow door are respectively connected by guide assemblies.

[0023] The elevator door assembly in the embodiments of the present application includes a shutter door, a slow door, and a middle door, and is therefore applicable to elevator systems including landing doors with at least three different operating speeds. The sill of the elevator door assembly is formed with a first guide groove, which is disposed on the side of the sill and opens downward. Compared to the related art method of providing a guide groove on the top surface of the sill, the first guide groove located on the side of the sill and opening downward is less likely to accumulate debris, thereby reducing the risk of problems such as jamming and malfunction of the elevator door.

[0024] On this basis, the shutter is equipped with a first guide member, which cooperates with the first guide groove. During the process of opening or closing the shutter, the first guide member moves along the first guide groove, thereby preventing the shutter from shifting during movement. A second guide member is provided on the top surface of the sill, and a second guide groove is provided at the bottom of the slow door. The second guide groove cooperates with the second guide member. During the process of opening or closing the slow door, relative movement occurs between the second guide groove and the second guide member, thereby preventing the slow door from shifting during movement. The shutter and the middle door, as well as the middle door and the slow door, are connected by guide assemblies, respectively. The limiting and motion guiding functions of the guide assemblies prevent the middle door from shifting during movement. It can be seen that the above-mentioned arrangement allows the shutter, slow door, and middle door to all obtain better guiding effects during movement. It can be seen that the elevator door assembly in this application is suitable for elevator systems with multiple landing doors.

[0025] In some embodiments, the guide assembly includes a third guide groove, a first connecting frame and a third guide member, the third guide member is connected to the first connecting frame, and the third guide member cooperates with the third guide groove; the third guide groove of one of the guide assemblies is set on the slow door, and the first connecting frame of the guide assembly is set on the middle door; the third guide groove of another guide assembly is set on the middle door, and the first connecting frame of the guide assembly is set on the shutter.

[0026] In this way, the middle door is connected to the shutter and slow door through different guide components, thereby preventing the middle door from shifting during movement, thereby improving the movement stability of the middle door.

[0027] In some embodiments, the number of the shutters is one or two, the number of the slow shutters is one or two, the number of the middle shutters is one or two, the number of the shutters is equal to the number of the slow shutters, and the number of the middle shutters is greater than or equal to the number of the shutters.

[0028] The elevator door assembly in the embodiment of the present application is applicable to both side-opening and bi-folding elevator doors. When the number of middle doors equals the number of shutters, one middle door is provided between each shutter and slow door. When the number of middle doors exceeds the number of shutters, at least two middle doors are provided between each shutter and slow door. In other words, the elevator door assembly in this embodiment can also be extended to include multiple middle doors with different operating speeds.

[0029] In some embodiments, when the number of the middle doors is greater than the number of the shutters, any two adjacent middle doors are connected by the guide assembly. This arrangement can ensure that any middle door has good movement stability.

[0030] Another embodiment of the present application provides an elevator system, which includes the elevator door assembly according to any one of the above embodiments.

[0031] The elevator system in the embodiment of the present application and the elevator door assembly in the above-mentioned embodiment are based on the same inventive concept. Therefore, the elevator system in the embodiment of the present application can obtain the beneficial effects of the elevator door assembly in the corresponding embodiment.

[0035] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0036] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] like Figures 1 to 6 As shown, one embodiment of the present application provides an elevator door assembly 1, comprising a sill 10, a shutter 20, and a slow door 30. The sill 10 extends in a first direction and is formed with a first guide groove 11. The first guide groove 11 extends in the first direction and is disposed on a side of the sill 10 with an opening facing downward. The shutter 20 is mounted with a first guide member 40 that cooperates with the first guide groove 11. The slow door 30 has a second guide groove 31 at its bottom that extends in the first direction. A second guide member 50 is disposed on the top surface of the sill 10 that cooperates with the second guide groove 31. The shutter 20 and the slow door 30 are further connected by a guide assembly 60.

[0039] Shutter 20 and slow door 30 are both landing doors of an elevator. Shutter 20 is the landing door that operates at a higher speed during most of the journey, while slow door 30 is the landing door that operates at a lower speed during most of the journey. It should be noted that the terms "higher speed" and "lower speed" are relative. That is, during most of the journey, the shutter 20 operates at a higher speed than the slow door 30. Generally speaking, when the elevator doors are fully open, the shutter 20 and slow door 30 overlap, or they largely overlap.

[0040] In the elevator door assembly 1 in the embodiment of the present application, the sill 10 is formed with a first guide groove 11. The first guide groove 11 is arranged on the side of the sill 10 and opens downward. Compared with the method of setting the guide groove on the top surface of the sill in the related art, the first guide groove 11 located on the side of the sill 10 and opening downward is not easy to accumulate debris, thereby reducing the risk of problems such as jamming and malfunction of the elevator door.

[0041] On this basis, the shutter 20 is equipped with a first guide member 40. The first guide member 40 cooperates with the first guide groove 11. During the opening or closing process of the shutter 20, the first guide member 40 moves along the first guide groove 11, thereby preventing the shutter 20 from deflecting during movement. A second guide member 50 is provided on the top surface of the sill 10, and a second guide groove 31 is provided on the bottom of the slow door 30. The second guide groove 31 cooperates with the second guide member 50. During the opening or closing process of the slow door 30, the second guide groove 31 and the second guide member 50 move relative to each other, thereby preventing the slow door 30 from deflecting during movement. It can be seen that the above-mentioned arrangement allows both the shutter 20 and the slow door 30 to obtain a good guiding effect during movement, that is, the elevator door assembly 1 of the present application is suitable for elevator systems with multiple landing doors.

[0042] In addition, the shutter 20 and the slow door 30 are connected by a guide assembly 60. For the slow door 30, the guide assembly 60 provides a mating connection point for the slow door 30, and the second guide member 50 also provides a mating connection point for the slow door 30. This reduces the number of second guide members 50 required. For example, one or two second guide members 50 may be provided for each slow door 30, and the second guide members 50 are positioned so as to cover the slow door 30 in both the open and closed states. This arrangement not only improves the stability of the slow door 30 but also prevents the second guide member 50 from being exposed when the slow door 30 is fully open, thereby preventing a user from tripping or stepping on the second guide member 50 and injuring themselves.

[0043] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, in some embodiments, the shutter 20 is installed with two first guide members 40, and the two first guide members 40 are arranged at intervals along the first direction. The second guide groove 31 of the slow shutter 30 cooperates with the two second guide members 50, and the two second guide members 50 are arranged at intervals along the first direction. The spacing between the second guide members 50 is less than or equal to 1 / 10 of the spacing between the two first guide members 40.

[0044] The shutter 20 is equipped with two first guide members 40, which are arranged at intervals along the first direction. The two first guide members 40 have a significant spacing along the first direction, and both first guide members 40 cooperate with the first guide groove 11 on the sill 10, thereby improving the movement stability of the shutter 20 during the opening or closing process.

[0045] The second guide groove 31 of the slow door 30 cooperates with two second guide members 50, that is, the number of second guide members 50 cooperating with one slow door 30 is two, and the spacing between the two second guide members 50 is significantly smaller than the spacing between the two first guide members 40. In this way, the positions of the two second guide members 50 are relatively close, and the two second guide members 50 can be set at a position close to the door frame. Therefore, when the slow door 30 is fully open, the second guide member 50 can be avoided from being exposed to the outside, so as to avoid the user tripping or stepping on the second guide member 50 and being injured.

[0046] like Figure 4 、 Figure 6 As shown, in one embodiment, the guide assembly 60 includes a third guide slot 62, a first connecting frame 63, and a third guide member 61. The third guide slot 62 is provided on the shutter 30 and extends along a first direction. One end of the first connecting frame 63 is connected to the shutter 20. The third guide member 61 is connected to the other end of the first connecting frame 63 and engages with the third guide slot 62.

[0047] During the movement of the shutter 20 relative to the slow door 30, the shutter 20 drives the third guide member 61 to move relative to the slow door 30 via the first connecting frame 63, causing the third guide member 61 to move along the third guide slot 62. Since the third guide member 61 is always in the third guide slot 62, the third guide member 61 and the third guide slot 62 always maintain a mating relationship. In this way, even if the number of second guide members 50 is reduced, for example, only one second guide member 50 is required to mate with each slow door 30, the stability of the movement of the slow door 30 during opening and closing can be ensured.

[0048] like Figure 1 、 Figure 4 As shown, in one embodiment, the first connecting frame 63 is connected to the side wall of the shutter 20 at one end along the first direction.

[0049] It is understandable that when the elevator door is in a fully open state, the shutter 20 and the slow door 30 are in an overlapping state or mostly overlap each other; when the elevator is in a closed state, one end of the shutter 20 along the first direction is in an overlapping state with the slow door 30.

[0050] Therefore, by arranging the first connecting frame 63 on the side wall of one end of the shutter 20 along the first direction (the end of the shutter 20 along the first direction close to the slow door 30 when the elevator door is in the closed state), it can be ensured that no matter what position the shutter 20 moves to, the third guide member 61 and the third guide groove 62 can always maintain a matching relationship, thereby ensuring that the slow door 30 can always obtain good movement stability.

[0051] like Figure 3 、 Figure 6 As shown, in one embodiment, the opening of the third guide slot 62 is set upward, the opening of the second guide slot 31 is set downward, and the second guide slot 31 is located directly below the third guide slot 62. This arrangement ensures that the third guide member 61 cooperates with the third guide slot 62 and the second guide member 50 cooperates with the second guide slot 31, so that the third guide slot 62 and the second guide slot 31 are arranged in the vertical direction. This helps to reduce the thickness of the slow door 30 and prevent the slow door 30 from being too thick.

[0052] In one embodiment, the third guide groove 62 and the second guide groove 31 are an integrated structure, which can save manufacturing steps and reduce costs during processing.

[0053] In some other embodiments, the third guide groove 62 and the second guide groove 31 may also be separate structures, that is, they are formed separately. It is understandable that when the third guide groove 62 and the second guide groove 31 are separate structures, the third guide groove 62 and the second guide groove 31 may be connected together or not connected to each other.

[0054] In one embodiment, the first guide member 40, the second guide member 50, and the third guide member 61 are guide wheels or guide sliders. The guide wheels can roll along the guide grooves, and the guide sliders can slide along the guide grooves. It is understood that the guide sliders can be configured in various shapes, such as plates, blocks, columns, disks, etc.

[0055] like Figure 6 As shown, in some embodiments, the first guide member 40 is connected to the side of the shutter 20 away from the slow shutter 30 along the second direction through the second connecting frame 70, and the second direction is perpendicular to the first direction.

[0056] One end of the second connecting frame 70 is connected to the shutter 20, and the other end is connected to the first guide member 40. The provision of the second connecting frame 70 allows the first guide member 40 and the shutter 20 to maintain a stable relative positional relationship, thereby enabling the first guide member 40 to effectively guide the shutter 20. In addition, the shutter 20 is typically disposed on the inner side of the slow door 30, that is, the shutter 20 is closer to the elevator car than the slow door 30. The second connecting frame 70 is connected to the side of the shutter 20 that is away from the slow door 30 along the second direction. This places the second connecting frame 70 on the inner side of the shutter 20. In this way, the user cannot see the second connecting frame 70 from the outside of the elevator car, thereby facilitating the maintenance of the external aesthetics of the elevator door assembly 1.

[0057] like Figure 1 、 Figure 7 As shown, in some embodiments, the number of shutters 20 is one or two, the number of slow shutters 30 is one or two, and the number of shutters 20 is equal to the number of slow shutters 30.

[0058] like Figure 1 As shown, when the number of the shutter door 20 and the number of the slow door 30 are both one, the elevator door is configured to open and close in a side-by-side manner. Figure 7 As shown, when there are two shutters 20 and two slow doors 30, the elevator door is configured to open and close in a biparting manner. When the elevator door is closed, the two shutters 20 move toward each other, and the two slow doors 30 also move toward each other. When the elevator door is opened, the two shutters 20 move away from each other, and the two slow doors 30 also move away from each other. In other words, the elevator door assembly 1 in the embodiment of the present application is applicable to both side-opening elevator doors and biparting elevator doors.

[0059] like Figure 8 As shown, another embodiment of the present application provides an elevator door assembly 1, comprising a sill 10, a shutter 20, a slow door 30, and a middle door 80. The sill 10 extends in a first direction and is formed with a first guide groove 11. The first guide groove 11 extends in the first direction and is disposed on the side of the sill 10, with the opening facing downward. A first guide member 40 is mounted below the shutter 20, engaging with the first guide groove 11. A second guide groove 31 is disposed at the bottom of the slow door 30, extending in the first direction. A second guide member 50 is disposed on the top surface of the sill 10, engaging with the second guide member 50. In a second direction, the middle door 80 is located between the shutter 20 and the slow door 30, with the second direction being perpendicular to the first direction. Guide assemblies 60 connect the shutter 20 and the middle door 80, as well as the middle door 80 and the slow door 30, respectively.

[0060] The middle door 80 is also a landing door of the elevator. The middle door 80 refers to the landing door that runs at a medium speed during most of the journey. Here, the "medium speed" is also relative, that is, during most of the journey, the running speed of the middle door 80 is higher than the running speed of the slow door 30, but lower than the running speed of the shutter 20.

[0061] The elevator door assembly 1 in the embodiment of the present application includes a shutter door 20, a slow door 30, and a middle door 80, and is therefore applicable to elevator systems including at least three landing doors with different operating speeds. The sill 10 in the elevator door assembly 1 is formed with a first guide groove 11. The first guide groove 11 is disposed on the side of the sill 10 and opens downward. Compared to the related art method of providing a guide groove on the top surface of the sill, the first guide groove 11 located on the side of the sill 10 and opening downward is less likely to accumulate debris, thereby reducing the risk of problems such as jamming and malfunction of the elevator door.

[0062] On this basis, the shutter 20 is equipped with a first guide member 40. The first guide member 40 cooperates with the first guide slot 11. During the opening and closing of the shutter 20, the first guide member 40 moves along the first guide slot 11, thereby preventing the shutter 20 from deflecting during movement. A second guide member 50 is provided on the top surface of the sill 10, and a second guide slot 31 is provided on the bottom of the slow door 30. The second guide slot 31 cooperates with the second guide member 50. During the opening and closing of the slow door 30, the second guide slot 31 and the second guide member 50 move relative to each other, thereby preventing the slow door 30 from deflecting during movement. The shutter 20 and the middle door 80, as well as the middle door 80 and the slow door 30, are connected by guide assemblies 60, respectively. The guide assemblies 60 provide position limiting and motion guidance, preventing the middle door 80 from deflecting during movement. Thus, the above arrangement provides effective guidance for the shutter 20, the slow door 30, and the middle door 80 during movement. It can be seen that the elevator door assembly 1 in the present application is applicable to an elevator system with multiple landing doors.

[0063] like Figure 8 As shown, in some embodiments, the guide assembly 60 includes a third guide slot 62, a first connecting bracket 63, and a third guide member 61. The third guide member 61 is connected to the first connecting bracket 63, and the third guide member 61 engages with the third guide slot 62. The third guide slot 62 of one guide assembly 60 is disposed on the slow door 30, and the first connecting bracket 63 is disposed on the middle door 80. The third guide slot 62 of another guide assembly 60 is disposed on the middle door 80, and the first connecting bracket 63 is disposed on the shutter 20.

[0064] The third guide slot 62 of one guide assembly 60 is disposed on the slow door 30, and the first connecting bracket 63 of the guide assembly 60 is disposed on the middle door 80. The third guide slot 62 of the other guide assembly 60 is disposed on the middle door 80, and the first connecting bracket 63 of the guide assembly 60 is disposed on the shutter 20. In this way, the middle door 80 is connected to the shutter 20 and the slow door 30 via different guide assemblies 60, respectively. This prevents the middle door 80 from deviating during movement, thereby improving the movement stability of the middle door 80.

[0065] You can refer to Figure 1 In some embodiments, the shutter 20 is installed with two first guide members 40, and the two first guide members 40 are arranged at intervals along the first direction. The second guide groove 31 of the slow shutter 30 cooperates with the two second guide members 50, and the two second guide members 50 are arranged at intervals along the first direction. The spacing between the second guide members 50 is less than or equal to 1 / 10 of the spacing between the two first guide members 40.

[0066] The shutter 20 is equipped with two first guide members 40, which are arranged at intervals along the first direction. The two first guide members 40 have a significant spacing along the first direction, and both first guide members 40 cooperate with the first guide groove 11 on the sill 10, thereby improving the movement stability of the shutter 20 during the opening or closing process.

[0067] The second guide groove 31 of the slow door 30 cooperates with two second guide members 50, that is, the number of second guide members 50 cooperating with one slow door 30 is two, and the spacing between the two second guide members 50 is significantly smaller than the spacing between the two first guide members 40. In this way, the positions of the two second guide members 50 are relatively close, and the two second guide members 50 can be set at a position close to the door frame. Therefore, when the slow door 30 is fully open, the second guide member 50 can be avoided from being exposed to the outside, so as to avoid the user tripping or stepping on the second guide member 50 and being injured.

[0068] You can refer to Figure 1 and Figure 7 In one embodiment, the number of shutters 20 is one or two, the number of slow shutters 30 is one or two, and the number of middle shutters 80 is one or two. The number of shutters 20 is equal to the number of slow shutters 30, and the number of middle shutters 80 is greater than or equal to the number of shutters 20.

[0069] When there is only one shutter door 20 and one slow door 30, the elevator door is configured to open and close in a side-opening manner. When there are two shutter doors 20 and two slow doors 30, the elevator door is configured to open and close in a biparting manner. Therefore, the elevator door assembly 1 in the embodiment of the present application is applicable to both side-opening elevator doors and biparting elevator doors.

[0070] When the number of middle doors 80 is equal to the number of shutters 20, one middle door 80 is provided between each shutter 20 and slow door 30. When the number of middle doors 80 is greater than the number of shutters 20, at least two middle doors 80 are provided between each shutter 20 and slow door 30. In other words, the elevator door assembly 1 of this embodiment can also be extended to a case where multiple middle doors 80 are provided at different operating speeds.

[0071] In one embodiment, when the number of the middle doors 80 is greater than the number of the shutters 20, any two adjacent middle doors 80 are connected by a guide assembly 60. This arrangement can ensure that any middle door 80 has good movement stability.

[0072] Another embodiment of the present application provides an elevator system, which includes the elevator door assembly 1 in any of the above embodiments.

[0073] The elevator system in the embodiment of the present application and the elevator door assembly 1 in the above embodiment are based on the same inventive concept. Therefore, the elevator system in the embodiment of the present application can obtain the beneficial effects of the elevator door assembly 1 in the corresponding embodiment.

[0074] The above content is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
