Description

Technical Field

[0001] This application relates to the technical field of traffic management, and particularly to a rail transit self-aligning platform door system. Background Art

[0002] The platform door system was first applied in subway lines to prevent traffic accidents between passengers and incoming trains. Since the train models planned to run on each subway line were the same before, when the train stopped at the calibration point on the subway platform, the position of the train doors was always fixed. Therefore, when setting up the subway platform door system, it was not necessary to consider the differences in the opening positions of train doors of different models and the widths of train doors of different models.

[0003] With the gradual popularization of the cross-line operation mode of urban rail transit, there are situations where electric multiple units of different models stop at the same platform on the same / different lines, and different car formations are adopted. If the existing subway platform doors are used, it will cause the doors of some trains to be difficult to align with the sliding doors of the platform door system, blocking passengers from getting on and off the train, inconvenient access, the passing width not meeting the safety code requirements, and hindering the operation demand of rapid passenger boarding and alighting at the station.

[0004] In recent years, research and innovation have been carried out on the above problems, and various new types of platform door test schemes such as large-opening platform doors, translational platform doors, and up-and-down lifting platform doors have been derived and developed on the basis of conventional platform doors. Compared with conventional platform doors, they can adapt to various door positions to a certain extent. However, large-opening platform doors and translational platform doors have problems such as too long opening time affecting the train stop time, still having some parts of the train doors blocked, having to be installed recessed, occupying a large amount of waiting space at the station, and being too costly. The up-and-down lifting platform door has the problem that it does not completely isolate the waiting area and the track area and cannot effectively prevent people from breaking into the track area.

However, after understanding the disclosure of the present application, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example and is not limited to the order set forth herein, but rather changes that will be apparent after understanding the disclosure of the present application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0036] The features described herein can be implemented in various forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0037] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0038] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0039] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another component, element, region, layer, or part. Thus, a first component, element, region, layer, or part referred to in the examples described herein may also be referred to as a second component, element, region, layer, or part without departing from the teachings of the examples.

[0040] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprising", "including" and "having" enumerate the stated features, quantities, operations, components, elements and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0042] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Accordingly, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0043] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible, as will be apparent after understanding the disclosure of the present application.

[0044] Before the present application was proposed, compared with conventional platform doors, existing test schemes for various new types of platform doors such as large-opening platform doors, sliding platform doors, and up-and-down lifting platform doors could, to a certain extent, adapt to multiple door positions. However, large-opening platform doors and sliding platform doors have problems such as too long door opening time affecting the train stop time, some parts of the train doors are still blocked, they must be installed with a recess, occupying a large amount of waiting space in the station, and the cost is too high. The up-and-down lifting platform doors have the problem that they do not completely isolate the waiting area and the track area and cannot effectively prevent people from breaking into the track area.

[0045] In view of this, the present application provides a rail transit self-aligning platform door system to solve the above technical problems. The following refers to Figures 1 to 11 Describe the rail transit self-aligning platform door system according to some embodiments of the present application.

[0046] The rail transit self-aligning platform door system of the present application is applied to vehicle A and vehicle B on a rail line. As Figure 12 shown, taking the misalignment distance between two corresponding doors of vehicle A and vehicle B of the present application as 0 to 1.4 m as an example, any two misaligned doors of vehicle A and vehicle B of the present application cooperate with one platform door unit of the present application.

[0047] That is to say, the rail transit self-aligning platform door system of the present application includes a plurality of platform door units to cooperate with any two misaligned doors of vehicles A and B. The following will describe by taking one platform door unit as an example.

[0048] As Figure 1 and Figure 2As shown in the figure, each platform door unit includes a passage opening 500 and platform doors. The platform doors include a left sliding door 100, a middle sliding door 200, and a right sliding door 300. Among them, the passage opening 500 includes a left side and a right side that are opposite to each other in the first direction X. The left sliding door 100, the middle sliding door 200, and the right sliding door 300 can completely cover the passage opening 500, and the three can automatically move along the first direction X according to the docking positions of Train A and Train B to define the opening of the passage opening 500. Among them, the total width of the passage opening 500 can cover the door openings of Train A and Train B. The docking position of the doors of Train B is closer to the left side of the passage opening 500 than that of Train A. When Train B docks, the left sliding door 100 slides to the left, and the middle sliding door 200 and the right sliding door 300 slide to the right, so that the passage opening 500 exposed between the left sliding door 100 and the middle sliding door 200 faces the door opening of Train B. When Train A docks, the right sliding door 300 slides to the right, and the middle sliding door 200 and the left sliding door 100 slide to the left, so that the passage opening 500 exposed between the right sliding door 300 and the middle sliding door 200 faces the door opening of Train A.

[0049] As described above, the present application provides a rail transit self-aligning platform door system that can be installed close to the platform and automatically align with the doors of different vehicle models. On the basis of the standard platform doors, a new movable middle sliding door 200 is added. The platform doors composed of the middle sliding door 200, the left sliding door 100, and the right sliding door 300 can automatically define the opening of the passage opening 500 according to the docking positions of Train A and Train B. That is, the position of the passage opening 500 formed by the platform doors can be changed according to the door position, realizing the function of automatically aligning the platform doors with the door positions, and changing the disadvantages of the traditional fixed opening channel of the platform doors.

[0050] Compared with the prior art, on the one hand, the opening / closing time of the present application is the same as that of the conventional platform doors, and there will be no problem that the opening time is too long and affects the train stop time. On the other hand, the present application automatically aligns with the doors of different vehicle models, there will be no problem that the train doors are blocked, and the width of the additional passage opening 500 will not be increased. It can not only effectively prevent people from breaking into the track area, but also does not require a recessed installation, saving a large amount of waiting space in the station.

[0051] In the embodiment of the present application, as Figure 2 、 Figure 10 and Figure 11As shown, the rail transit self-aligning platform door system of the present application further includes a guide rail 840; the platform door further includes fixed doors 400 arranged on both sides of the passage opening 500. Among them, the guide rail 840 extends along the first direction X and is arranged on the front side or the rear side of the fixed door 400. The left sliding door 100, the middle sliding door 200, and the right sliding door 300 are all slidably connected to the guide rail 840. With such an arrangement, the left sliding door 100, the middle sliding door 200, and the right sliding door 300 can all slide along the guide rail 840 to adjust the opening degree of the passage opening 500.

[0052] In the following, taking the misalignment distance between the corresponding two doors of vehicle A and vehicle B being 0 to 1.4 m as an example, it will be described in detail how the present application realizes the specific opening degrees of the left sliding door 100, the middle sliding door 200, and the right sliding door 300 according to the specific docking positions of vehicle A / vehicle B.

[0053] As Figure 2 and Figure 3 shown, define the door opening degrees of vehicle A and vehicle B in the first direction X when docking as C A and C B , C B and C A The misalignment distance in the first direction X is L (L is, for example, 0 to 1.4 m), and the width of the middle sliding door 200 is equal to the misalignment distance L. C A and C B are, for example, 0.9 to 1.4 m.

[0054] Define that when vehicle B docks, the opening degree of the passage opening 500 that needs to be exposed between the left sliding door 100 and the middle sliding door 200 is L B , where L B > C B . Define that when vehicle A docks, the opening degree of the passage opening 500 that needs to be exposed between the right sliding door 300 and the middle sliding door 200 is L A , where L A > C A , L B = L A , C A = C B . L B and L A are, for example, 1.5 to 2 m.

[0055] The widths of the left sliding door 100 and the right sliding door are both L B / 2; when the left sliding door 100, the middle sliding door 200, and the right sliding door 300 are all in the closed state, the two side edges of the middle sliding door 200 are respectively aligned with the midlines of C B and C A , and the two side edges of the middle sliding door 200 are respectively aligned with L Band the median line of L A is aligned with the median line.

[0056] Set like this, as Figure 4 shown, when vehicle B docks, the left sliding door 100 slides to the left by a distance of L B / 2 to completely slide to the front or rear side of the fixed door 400. The middle sliding door 200 follows the right sliding door 300 and slides to the right, and the sliding distance is L B / 2. The right sliding door 300 completely slides to the front or rear side of the fixed door 400. In this way, the passage opening 500 exposed between the left sliding door 100 and the middle sliding door 200 is directly opposite the door opening of vehicle B. At this time, the width of the passage opening 500 is L B .

[0057] That is to say, when vehicle B parks according to the unified parking sign, at this time, at the position corresponding to the platform door of the vehicle door, after the left sliding door 100 retracts into the fixed door 400 and the right sliding door 300 retracts into the fixed door 400, the middle sliding door 200 follows the right sliding door 300 and moves a distance of L B / 2, thus forming an unobstructed passage corresponding to the vehicle door (determined according to the vehicle door width, about 1.5m - 2m), which can be completely aligned with the vehicle door of the current parked vehicle and does not obstruct passengers from getting off.

[0058] Similarly, as Figure 5 shown, when vehicle A docks, the right sliding door 300 slides to the right by a distance of L A / 2 to completely slide to the front or rear side of the fixed door 400. The middle sliding door 200 follows the left sliding door 100 and slides to the left, and the sliding distance is L A / 2. The left sliding door 100 completely slides to the front or rear side of the fixed door 400. In this way, the passage opening 500 exposed between the right sliding door 300 and the middle sliding door 200 is directly opposite the door opening of vehicle A. At this time, the width of the passage opening 500 is L A .

[0059] That is to say, when vehicle A parks according to the unified parking sign, at this time, at the position corresponding to the platform door of the vehicle door, after the right sliding door 300 retracts into the fixed door 400 and the left sliding door 100 retracts into the fixed door 400, the middle sliding door 200 follows the left sliding door 100 and moves a distance of L A / 2, thus forming an unobstructed passage corresponding to the vehicle door (determined according to the vehicle door width, about 1.5m - 2m), which can be completely aligned with the vehicle door of the current parked vehicle and does not obstruct passengers from getting off.

[0060] In summary, the moving strokes of the left sliding door 100 and the right sliding door 300 of the present application are consistent with those of the conventional platform screen door. The middle sliding door 200 moves following the left sliding door 100 or the right sliding door 300. The opening / closing time of the platform screen door unit can be consistent with that of the conventional platform screen door, without causing a change in the moving distance of the door body due to the change of the opening channel, without increasing the opening / closing time, and without affecting train operation.

[0061] In the embodiment of the present application, as Figure 2 , Figure 10 and Figure 11 shown, the rail transit self-aligning platform screen door system further includes a door post steel structure 810 fixed inside the fixed door 400, a sill 820 fixed below the platform screen door, and a top box 830 arranged above the passage opening 500.

[0062] In the embodiment of the present application, as Figure 6 shown, the rail transit self-aligning platform screen door system further includes a driving motor 610, a driving wheel 620, a reverse wheel 630 and a toothed synchronous belt 640 arranged above the passage opening 500. Among them, a guide rail 840 is arranged below the passage opening 500 and on the sill 820. The driving motor 610 is connected to the driving wheel 620, and the driving wheel 620 and the reverse wheel 630 are connected by the toothed synchronous belt 640 in a transmission manner; the toothed synchronous belt 640 includes a first section 641 and a second section 642 that are parallel to each other vertically. The left sliding door 100 is fixedly connected to the second section 642, and the right sliding door 300 is fixedly connected to the first section 641.

[0063] That is to say, the left sliding door 100 and the right sliding door 300 are connected by the same toothed synchronous belt 640. One end of the toothed synchronous belt 640 is provided with a driving motor 610 and a driving wheel 620, and the other end is provided with a reverse wheel 630. When the driving motor 610 rotates clockwise, the left sliding door 100 can be moved to the left behind the fixed door 400, and the right sliding door 300 can be moved to the right behind the fixed door 400, and the opening action of this unit is completed; when the driving motor 610 rotates counterclockwise, the left sliding door 100 can be moved to the right to the closing position, and the right sliding door 300 can be moved to the left to the closing position, and the opening action of this unit is completed.

[0064] As described above, one driving motor 610 and one set of door unit controllers are provided in each platform screen door unit of the present application. Compared with the conventional platform screen door system, the number of driving motors is not increased additionally, and the number of door motor controllers is not increased additionally, and the cost is relatively low. The added middle sliding door 200 can be driven by the left sliding door 100 and the right sliding door 300 to different positions, realizing the function of automatically aligning the opening position of the platform screen door with the car door.

[0065] Furthermore, in the embodiment of the present application, in order to facilitate the movement of the middle sliding door 200, asFigure 6 As shown, the rail transit self-aligning platform door system further includes a left linkage locking mechanism 710 and a right linkage locking mechanism 720. Among them, the left sliding door 100 and the middle sliding door 200 are connected by the left linkage locking mechanism 710, and the right sliding door 300 and the middle sliding door 200 are connected by the right linkage locking mechanism 720; when car B docks, the right linkage locking mechanism 720 connects the middle sliding door 200 and the right sliding door 300, and the left linkage locking mechanism 710 disconnects the middle sliding door 200 and the left sliding door 100. When car A docks, the left linkage locking mechanism 710 connects the middle sliding door 200 and the left sliding door 100, and the right linkage locking mechanism 720 disconnects the middle sliding door 200 and the right sliding door 300.

[0066] That is to say, in this application, two left linkage locking mechanisms 710 are provided between the left sliding door 100 and the middle sliding door 200, which can meet the linkage locking function of the middle sliding door 200 and the left sliding door 100 in different opening modes, so that the middle sliding door 200 can move leftward following the left sliding door 100, and the position of the middle sliding door 200 can perform translational motion according to the system command at different opening position requirements, realizing the channel switching function.

[0067] Similarly, two right linkage locking mechanisms 720 are provided between the right sliding door 300 and the middle sliding door 200, which can meet the linkage locking function of the middle sliding door 200 and the right sliding door 300 in different opening modes, so that the middle sliding door 200 can move rightward following the right sliding door 300, and the position of the middle sliding door 200 can perform translational motion according to the system command at different opening position requirements, realizing the channel switching function.

[0068] In an embodiment of this application, in one example, as Figure 7 shown, the left linkage locking mechanism 710 includes a left main lock mechanism 711 and a left locked mechanism 712; the left main lock mechanism 711 is arranged on the left sliding door 100, the left locked mechanism 712 is arranged on the middle sliding door 200, and a left electromagnetic coil and a left mechanical link are arranged inside the left main lock mechanism 711 to realize the telescopic function of the mechanical link, and the mechanical link drives the lock body to realize the device locking and device unlocking functions, so as to realize the linkage motion function and the unlocking and opening function of the middle sliding door 200 with the left sliding door 100 and the right sliding door 300. When the left electromagnetic coil is energized, the left mechanical link can disconnect the left main lock mechanism 711 from the left locked mechanism 712. Similarly, the right linkage locking mechanism 720 includes a right main lock mechanism 721 and a right locked mechanism 722; the right main lock mechanism 721 is arranged on the right sliding door 300, the right locked mechanism 722 is arranged on the middle sliding door 200, and a right electromagnetic coil and a right mechanical link are arranged inside the right main lock mechanism 721. When the right electromagnetic coil is energized, the right mechanical link can disconnect the right main lock mechanism 721 from the right locked mechanism 722.

[0069] When car A stops, the door unit controller controls the right electromagnetic coil to be energized, that is, the left linkage locking mechanism 710 connects the middle sliding door 200 and the left sliding door 100, and the right linkage locking mechanism 720 disconnects the middle sliding door 200 and the right sliding door 300. When car B stops, the door unit controller controls the left electromagnetic coil to be energized, that is, the right linkage locking mechanism 720 connects the middle sliding door 200 and the right sliding door 300, and the left linkage locking mechanism 710 disconnects the middle sliding door 200 and the left sliding door 100.

[0070] Continue to see Figure 7 In one example, the left linkage locking mechanism 710 further includes a left sensor, which can detect the state of the left main lock mechanism 711. When the door unit controller controls the left electromagnetic coil to be energized and the state of the left main lock mechanism 711 is disconnected, the door unit controller controls the drive motor 610 to rotate forward (the drive motor 610 rotates clockwise). In addition, the left linkage locking mechanism 710 further includes a left manual unlocking port 714. There are two left main lock mechanisms 711 and two left locked mechanisms 712. The two left main lock mechanisms 711 and the two left locked mechanisms 712 are arranged vertically at intervals. The left manual unlocking port 714 is respectively connected to the two left main lock mechanisms 711 through the left linkage mechanism 715 to disconnect the two left main lock mechanisms 711 from the two left locked mechanisms 712.

[0071] Similarly, the right linkage locking mechanism 720 also includes a right sensor, which can detect the state of the right main lock mechanism 721. When the door unit controller controls the right electromagnetic coil to be energized and the state of the right main lock mechanism 721 is disconnected, the door unit controller controls the drive motor 610 to reverse (the drive motor 610 rotates counterclockwise). In addition, the right linkage locking mechanism 720 also includes a right manual unlocking port 724. There are two right main lock mechanisms 721 and two right locked mechanisms 722. The two right main lock mechanisms 721 and the two right locked mechanisms 722 are arranged vertically at intervals. The right manual unlocking port 724 is respectively connected to the two right main lock mechanisms 721 through the right linkage mechanism 725 to disconnect the two right main lock mechanisms 721 from the two right locked mechanisms 722.

[0072] That is, the left sliding door 100, the middle sliding door 200, and the right sliding door 300 all have the function of automatically closing and locking, and any single door can be independently unlocked, or multiple doors can be unlocked in conjunction with each other through the left manual unlocking port 714 or the right manual unlocking port 724. For example, any single door can be independently unlocked, or multiple doors can be unlocked in conjunction with each other through a manual emergency unlocking handle and a key.

[0073] Continue to see Figure 7, in one example, for the convenience of installing each component and the follow-up movement of the middle sliding door 200. A left square tube 713 is fixed to the inner side of the left sliding door 100, and a right square tube 723 is fixed to the inner side of the right sliding door 300. Middle square tubes 210 are respectively fixed to both sides of the middle sliding door 200. Among them, the left main lock mechanism, the sensor cable 716, the left main lock mechanism 711, the left manual unlocking port 714, and the left linkage mechanism 715 are fixed inside the left square tube 713, and the left locked mechanism 712 is fixed inside the middle square tube 210. The right main lock mechanism, the sensor cable 726, the right main lock mechanism 721, the right manual unlocking port 724, and the right linkage mechanism 725 are fixed inside the right square tube 723, and the right locked mechanism 722 is fixed inside the middle square tube 210.

[0074] In an embodiment of the present application, in another example, as Figure 8 shown, the left linkage locking mechanism 710 includes a left electromagnetic coil device and a left permanent magnet. Among them, the left electromagnetic coil device is arranged on the left sliding door 100, and the left permanent magnet is arranged on the middle sliding door 200. When the left electromagnetic coil device is powered on, the left electromagnetic coil is connected to the left permanent magnet, and when the left electromagnetic coil device is powered off, the left permanent magnet is disconnected from the left permanent magnet. Similarly, the right linkage locking mechanism 720 includes a right electromagnetic coil device and a right permanent magnet. Among them, the right electromagnetic coil device is arranged on the right sliding door 300, and the right permanent magnet is arranged on the middle sliding door 200. When the right electromagnetic coil device is powered on, the right electromagnetic coil is connected to the right permanent magnet, and when the right electromagnetic coil device is powered off, the right permanent magnet is disconnected from the right permanent magnet.

[0075] When vehicle A docks, the door unit controller controls the left electromagnetic coil device to be powered on and the right electromagnetic coil device to be powered off; when vehicle B docks, the door unit controller controls the right electromagnetic coil device to be powered on and the left electromagnetic coil device to be powered off.

[0076] As described above, by arranging an electromagnetic coil device on the left sliding door 100 and the right sliding door 300, and arranging permanent magnets on both sides of the middle sliding door 200 adjacent to the left sliding door 100 / right sliding door 300, the rail transit self-aligning platform door system can power on the electromagnetic coil device on the left sliding door 100 / right sliding door 300 to generate electromagnetic force, and can realize the linkage movement function of the middle sliding door 200 with the left sliding door 100 / right sliding door 300. When the power supply of the electromagnetic coil device is disconnected, the unlocking and opening function of the middle sliding door 200 with the left / right sliding door 300 can be realized.

[0077] In addition, it is worth mentioning that, as Figure 9 shown, the rail transit self-aligning platform door system of the present application can be applied to a semi-high rail transit self-aligning platform door system or a full-height rail transit self-aligning platform door system.

[0078] In summary, the present application provides a rail transit self-aligning platform door system that can be installed flush with the platform and automatically align with the doors of different vehicle models. On the basis of a standard platform door, a movable middle sliding door 200 is added. The platform door formed by the middle sliding door 200, the left sliding door 100, and the right sliding door 300 can automatically limit the opening of the passage opening 500 according to the docking positions of Train A and Train B. That is, the position of the passage opening 500 formed by the platform door can be changed according to the position of the vehicle door, realizing the function of automatically aligning the platform door with the vehicle door position and changing the drawback of the fixed opening passage of the traditional platform door.

[0079] Compared with the prior art, on the one hand, the opening / closing time of the present application is the same as that of a conventional platform door, and there will be no problem that the opening time is too long and affects the train stop time; on the other hand, the present application automatically aligns with the doors of different vehicle models, there will be no problem that the train doors are blocked, and the width of the additional passage opening 500 will not be increased. It can not only effectively prevent people from breaking into the track area, but also does not require a recessed installation, saving a large amount of waiting space in the station.

[0080] Furthermore, the left sliding door 100, the middle sliding door 200, and the right sliding door 300 are on the same plane. The height and appearance style of the door leaves are the same. The left sliding door 100, the middle sliding door 200, and the right sliding door 300 are arranged side by side. The three door bodies can perform translational motion on the same track. According to the change in the position of the docking vehicle door and the correct instructions issued by the system, the middle sliding door 200 has the functions of interlocking movement and unlocking release with the left sliding door 100, and the middle sliding door 200 also has the functions of interlocking movement and unlocking release with the right sliding door 300. When different vehicles dock, the platform door control system adopts different operating logics to realize opening / closing at different positions and does not increase the exposed area of the vehicle outside the non-passage area.

[0081] Furthermore, the passage opening 500 can be automatically adjusted to align with the vehicle door, and there will be no problem that the platform door passage opening 500 is not aligned with the vehicle door passage. The rail transit self-aligning platform door system does not require a 1.2m recessed installation and can be installed flush with the platform, greatly saving the platform area of the station waiting area.

[0082] Furthermore, the rail transit self-aligning platform door system can adopt an automatic mode and manual operation in case of emergency, and both can realize the function of switching the opening position of the sliding door.

[0083] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit it.
