Description

Technical Field

[0001] This application relates to the technical field of platform screen doors, and more particularly to a platform screen door unit and a train platform. Background Technology

[0002] In public transportation systems such as urban rail transit and high-speed rail, platform screen doors are crucial facilities for ensuring passenger safety and train operation order. They physically separate the track area from the waiting area, preventing passengers from falling or accidentally entering the operating area, while also improving ventilation and reducing noise.

[0003] To adapt to the varying spatial layouts of public transportation stations, existing platform screen doors typically employ a modular prefabrication and on-site assembly production and installation model. Specifically, manufacturers disassemble the complete platform screen door into several independent modules (such as door body modules, frame modules, drive control modules, etc.) according to design specifications for factory prefabrication. After the modules are transported to the construction site, installers then assemble, fix, and debug each module step by step according to the preset assembly sequence and technical requirements, ultimately forming a complete platform screen door structure with full functionality.

[0004] While this method facilitates transportation, it has significant shortcomings in the installation process: First, it requires highly skilled installers, which can easily lead to problems such as inaccurate alignment and weak connections, affecting safety and stability; second, the on-site assembly process is lengthy and time-consuming, increasing costs and potentially interfering with the normal operation of the site.

[0005] Therefore, the existing platform screen door installation methods rely too heavily on personnel skills and involve complex processes, making it difficult to meet the efficiency requirements. There is an urgent need to develop a new type of platform screen door structure that is simpler and more efficient. Utility Model Content

[0006] This application provides a platform screen door unit to solve the problem that the existing platform screen door installation methods rely too much on personnel skills and have complex processes, making it difficult to meet the requirements for efficiency.

[0007] A platform screen door unit, wherein the platform screen door unit is an integrated structure with all internal mechanical and electrical connections completed at the factory, comprising:

[0008] The top box module has an upper connecting mechanism installed at one end, which is fixedly connected to the platform beam.

[0009] A door module is connected to the other end of the top box module, and the door module includes at least two independent doors that slide relative to each other;

[0010] The lower connecting mechanism is located at the bottom of the door module and is fixedly connected to the platform ground foundation.

[0011] Furthermore, the upper connection mechanism includes a mounting bracket and a mounting plate fixedly connected to the top box module;

[0012] The mounting plate and the mounting bracket are respectively provided with matching through holes;

[0013] It also includes fasteners, which pass through the through holes of the mounting bracket and the mounting plate in sequence to form a locking engagement, so as to assemble and fix the top box module and the upper connecting mechanism into one unit.

[0014] Furthermore, the two relatively sliding independent door bodies include a first door body and a second door body;

[0015] The lower connecting mechanism is provided with a first sliding groove that is fitted to the first door body and a second sliding groove that is fitted to the second door body.

[0016] The first gate and the second gate are staggered along the length of the platform.

[0017] Furthermore, the number of the first gate and the second gate is at least two;

[0018] The first gate and the second gate are arranged alternately along the length of the platform.

[0019] Furthermore, the movement directions of the first door and the second door can be independently configured to one of the following modes:

[0020] Slide in the same direction, slide in opposite directions, or slide towards each other;

[0021] The direction of movement is selected based on the position signal of the train doors.

[0022] Furthermore, the lower connecting mechanism includes a threshold and a support member;

[0023] The threshold is provided with the first groove and the second groove;

[0024] The bottom of the first door body is provided with a sliding guide block that slides in conjunction with the first sliding groove;

[0025] The bottom of the second door is provided with another sliding guide block that slides in conjunction with the second slide groove.

[0026] Furthermore, the sliding guide block includes a rigid inner core and a wear-resistant layer covering the outside of the rigid inner core.

[0027] Furthermore, the end of the support member that connects to the ground is provided with an elongated hole.

[0028] Furthermore, the top box module is equipped with a drive component;

[0029] Each drive component corresponds to a drive connection for one of the independent door bodies;

[0030] All cables and connectors between each drive component and the corresponding connected door body are connected, wired, and tested at the factory.

[0031] In addition, a train platform is proposed, including:

[0032] Multiple platform screen door units as described above are arranged continuously along the length of the platform.

[0033] The technical solutions provided in this application have the following advantages compared with the prior art:

[0034] This technical solution precisely addresses the core problems of traditional platform screen doors, such as installation reliance on specialized skills, cumbersome processes, low efficiency, and difficulty in quality control. By adopting an integrated structure with all internal mechanical and electrical connections prefabricated at the factory, the top box module, door module, and lower connecting mechanism are integrated into a prefabricated unit. On-site installation only requires fixing the upper connecting mechanism to the platform beam and the lower connecting mechanism to the ground foundation, completely eliminating on-site splicing and wiring between modules. This factory-prefabricated integrated approach and simple on-site fixing significantly reduce the reliance on the installation personnel's expertise. Ordinary operators can complete the fixing work with simple tools. Furthermore, the upper and lower connecting mechanisms simplify on-site installation and improve installation efficiency.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0054] This application discloses a platform door unit applicable to high-speed rail, subway, or other station scenarios.

[0055] like Figure 1 As shown, it includes: a top box module 2, one end of which is equipped with an upper connecting mechanism 1, which is fixedly connected to the platform beam through the upper connecting mechanism 1; a door module 3, which is connected to the other end of the top box module 2, and the door module 3 includes at least two relatively sliding independent door bodies; and a lower connecting mechanism 4, which is located at the bottom of the door module 3 and is fixedly connected to the platform ground foundation through the lower connecting mechanism 4.

[0056] It should be noted that the platform screen door unit in this technical solution is a fully integrated, one-piece structural design completed at the factory. Specifically, during the factory production stage, the assembly of all internal mechanical components and the connection of electrical wiring have been completed, and the core components have been pre-fixed. This includes the assembly and connection of the upper connecting mechanism 1 with the top box module 2, the assembly and connection of the top box module 2 with the door module 3, and the assembly and connection of the door module 3 with the lower connecting mechanism 4, forming a prefabricated unit with complete functions and a unified structure. Therefore, after the platform screen door unit is transported to the construction site, no further mechanical splicing or electrical wiring work between modules is required. Only two operations need to be completed before it can enter the testing and use stage: first, to connect the electrical system of the platform screen door unit to the power supply equipment at the construction site; and second, to achieve the installation and positioning of the overall structure by fixing the prefabricated upper connecting mechanism 1 to the platform beam and the lower connecting mechanism 4 to the platform ground foundation.

[0057] In this technical solution, both the upper connecting mechanism 1 and the lower connecting mechanism are made of rigid materials, such as stainless steel connecting brackets. During installation, the upper connecting mechanism 1 and the lower connecting mechanism are connected and fixed to the upper beam of the platform and the platform floor respectively by bolts or welding. In this way, the platform door can be installed quickly and effectively in the platform.

[0058] Detailed, such as Figure 2 As shown, the upper connecting mechanism 1 includes a mounting bracket 11 and a mounting plate 12 fixedly connected to the top box module 2; the mounting plate 12 and the mounting bracket 11 are respectively provided with matching through holes; it also includes fasteners, and the components work together to achieve the fixed assembly of the top box module 2 and the upper connecting mechanism 1, and the assembly process is completed before leaving the factory.

[0059] At the factory, simply insert the fastener (such as a screw) into the through hole of the mounting bracket 11 from one side, then through the through hole of the mounting plate 12, and finally put a nut on the protruding end of the fastener and tighten it. This will make the mounting bracket 11 and the surface of the mounting plate 12 fit tightly together, thereby firmly assembling the top box module 2 and the upper connecting mechanism 1 into one unit.

[0060] After the platform screen door unit is transported to the construction site, there is no need to adjust the assembly relationship between the upper connecting mechanism 1 and the top box module 2. Only the mounting bracket 11 of the upper connecting mechanism 1 needs to be fixedly connected to the platform beam to complete the installation and positioning of the upper end of the platform screen door unit.

[0061] Once the upper end of the platform door unit is fixed to the platform beam via the upper connecting mechanism 1, the lower end installation can begin. The lower end of the platform door unit is fixed to the platform ground via the lower connecting mechanism 4.

[0062] like Figure 3 , Figure 4 , Figure 5 As shown, the lower connecting mechanism 4 includes a threshold 43 and a support member 44. The support member 44 is the core component connecting the threshold 43 and the platform floor, and an elongated hole is provided at one end near the ground. The elongated hole extends along the width direction of the support member 44 to allow for adjustment of the support member 44's position relative to the ground in the width direction.

[0063] During installation, bolts are inserted through the elongated holes of the support member 44 and connected to the pre-installed fixed structure (such as ground embedded parts) on the platform ground. After tightening the bolts, the support member 44 can be firmly fixed on the platform. Since the threshold 43 and the support member 44 have been assembled before leaving the factory, the installation of the lower end of the entire platform door unit is completed after the support member 44 is fixed to the ground, thereby realizing the overall installation and fixation of the platform door unit.

[0064] This technical solution optimizes the installation process of platform screen door units by pre-assembling the core connection structure in the factory for easy on-site installation and fixing. Firstly, the assembly of the upper connection mechanism 1 with the top box module 2, and the assembly of the sill 43 with the support component 44 in the lower connection mechanism 4, are all completed in the factory, avoiding on-site assembly of complex components. Secondly, only three simple operations need to be completed on-site: fixing the upper connection mechanism 1 to the upper beam, connecting the support component 44 to the ground with bolts, and connecting the electrical and power supply equipment. This eliminates the need for installers to possess skills in module disassembly, mechanical reassembly, or complex wiring, significantly reducing the professional requirements for installers. Simultaneously, the simplified on-site procedures effectively shorten installation time and reduce quality fluctuations caused by multiple overlapping processes, ultimately achieving a dual improvement in installation efficiency and quality.

[0065] Furthermore, since each independent door in this technical solution can slide within its own track, and the sliding position of each independent door can be adjusted according to instructions, this technical solution not only solves the problem of existing platform screen doors having fixed opening positions and being unable to flexibly adapt to the door positions of different vehicle models, but also provides the beneficial effect of quickly and effectively installing the platform screen door in the platform through the upper connecting mechanism 1 and the lower connecting mechanism.

[0066] In a specific embodiment, such as Figure 3 As shown, the two relatively sliding independent doors include a first door 31 and a second door 32; the lower connecting mechanism 4 is provided with a first sliding groove 41 corresponding to the first door 31 and a second sliding groove 42 corresponding to the second door 32; the first door 31 and the second door 32 are staggered along the length of the platform.

[0067] In actual use, when the platform control system issues an opening command, the first door 31 slides along the first slide rail 41 under the driving action, and the second door 32 slides along the second slide rail 42. Since the two doors are staggered, they will not collide even if their sliding paths intersect. For example, if the first door 31 needs to slide a large distance to the right, and the second door 32 needs to slide to the left, they will move smoothly in their respective slide rails due to their different front and rear positions, accurately reaching the position of the corresponding train door. This ensures that the opening area is accurate and solves the problem of possible mutual interference when the doors slide.

[0068] In a specific embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the lower connecting mechanism 4 includes a threshold 43 and a support member 44; the threshold 43 is provided with a first sliding groove 41 and a second sliding groove 42; the bottom of the first door body 31 is provided with a sliding guide block 33 that slides in cooperation with the first sliding groove 41; the bottom of the second door body 32 is provided with another sliding guide block 33 that slides in cooperation with the second sliding groove 42.

[0069] It should be noted that each door body of this type of platform screen door is pre-embedded in the corresponding slide groove at the factory, so that during on-site installation, it is only necessary to connect and fix the upper connecting mechanism 1 and the lower connecting mechanism 4 to the upper beam of the platform and the platform ground, respectively.

[0070] When in use, after the door receives the sliding command, the sliding guide block 33 at the bottom is embedded in the groove on the threshold 43. As the driving force is transmitted, the sliding guide block 33 moves smoothly along the track of the groove. The support 44 is in contact with the platform ground and has a load-bearing function. It can support and fix the threshold 43 and prevent the threshold 43 from shaking or shifting when the door slides. For example, when the door needs to slide open quickly, the tight cooperation between the sliding guide block 33 and the groove can ensure that the door does not deviate from the track, reduce frictional resistance, and achieve smooth sliding.

[0071] Furthermore, such as Figure 6 As shown, the sliding guide block 33 includes a rigid inner core 331 and a wear-resistant layer 332 covering the outside of the rigid inner core 331.

[0072] The wear-resistant layer 332 can be made of wear-resistant materials such as rubber. When the sliding guide block 33 repeatedly slides open and close within the groove, the outer wear-resistant layer 332 directly contacts the groove and bears the friction. The rigid inner core 331 provides support for the entire sliding guide block 33, preventing it from deforming under stress. Even after long-term, high-frequency sliding, the wear-resistant layer 332 can effectively resist wear, maintaining the structural integrity and sliding performance of the sliding guide block 33. For example, in stations with high passenger flow and frequent door opening and closing, this structure can significantly reduce the wear of the sliding guide block 33, extend its service life, reduce maintenance costs and replacement frequency, and ensure long-term stable sliding of the door.

[0073] Furthermore, in a specific embodiment, the number of the first door 31 and the second door 32 is at least two; the first door 31 and the second door 32 are arranged alternately along the length of the platform.

[0074] In this embodiment, when a train with multiple doors enters the station, the system issues control commands to the first door 31 and the second door 32, which are arranged alternately, according to the position information of each door of the train. For example, if the first door of the train is located between the first door 31 and the adjacent second door 32, the system controls the first door 31 and the second door 32 to slide in opposite directions to form an opening channel to expose the first door.

[0075] For example, if the second door of the train is located between the next first door body 31 and the second door body 32, then the next first door body 31 and the second door body 32 are controlled to slide in opposite directions to form an opening channel to expose the second door.

[0076] This technical solution utilizes the sliding adjustment of individual door panels to ensure each door has a corresponding opening area, and allows for flexible adjustment of the opening range of adjacent doors based on door spacing. Furthermore, it enables the synchronous opening of the first and second doors. As long as the door position information for the train is pre-stored in the platform control system, when the train arrives at the station, the system can control the relative sliding of each individual door panel to open the corresponding door position. This design enhances adaptability to multi-door train models, flexibly handles different door spacings, and further improves the versatility and practicality of the platform screen door.

[0077] For example, in a specific embodiment, the movement direction of the first door 31 and the second door 32 can be independently configured as one of the following modes: sliding in the same direction, sliding in opposite directions, or sliding towards each other; wherein, the selection of the movement direction is based on the position signal of the train door.

[0078] In detail, when the platform control system receives the train door position signal, it will analyze the position of the door relative to the door module 3. If the door is located in the middle of the two doors, it will control the first door 31 and the second door 32 to slide open in opposite directions, that is, the first door 31 slides to the right and the second door 32 slides to the left to form a middle opening channel.

[0079] For example, when the train door is mainly located in the area of ​​the first door body 31 and partially extends into the second door body 32, the control system can be configured to allow both doors to slide in the same direction (e.g., both move to the right). In this case, the two doors slide to the right synchronously, creating a door opening channel on the left side, thereby matching the actual position requirements of the train door.

[0080] This design effectively solves the problems of existing technologies, such as the single direction of door movement and the inability to flexibly adjust the opening method according to different train door positions. It makes the door opening method more flexible and diverse, and can accurately match train doors in different positions, further improving the adaptability and ease of use of platform doors.

[0081] To ensure that each door has sufficient driving force when sliding, such as Figure 7 As shown, the top box module 2 is equipped with a drive component 21; each drive component 21 is connected to an independent door; all cables and connectors between each drive component 21 and the corresponding independent door are connected, wired and tested at the factory.

[0082] In this embodiment, the drive assembly 21 includes a motor, the output shaft of which is connected to a drive wheel. A belt is fitted around the outer circumference of the drive wheel, and the other end of the belt is connected to each door. When the DCU controls the motor drive corresponding to each door, the corresponding door moves through the transmission connection between the drive wheel and the belt.

[0083] For example, when only one door on the left needs to be opened, the corresponding drive component 21 for the left door is activated, while the drive component 21 for the right door remains inactive, and the door remains stationary. This allows for precise control of the movement of each door, preventing the adjustment of one door from affecting the status of other doors. It should be understood that this design ensures that each door can be driven independently, unaffected by other doors, thus solving the problem of doors being unable to be controlled independently due to drive linkage.

[0084] In addition, all cables and connectors between each drive component 21 and the corresponding connected independent door body are connected, wired and tested at the factory.

[0085] The purpose of this design is to avoid wiring errors and messy wiring caused by limited space and differences in personnel operation on site, thus ensuring the reliability of electrical connections from the source. On the other hand, once the platform gate unit has completed the structural fixation of the upper and lower ends on the construction site, there is no need to install or debug the electrical parts of the drive components and the gate body. It can directly enter the overall functional testing stage, which greatly simplifies the on-site operation process, shortens the cycle from installation to testing and use, and avoids the cumbersome procedures and quality risks brought about by on-site electrical wiring.

[0086] Furthermore, in order to determine the specific movement state of each door, such as to avoid the situation where the platform system judges that the door has opened to the correct position while the door is still sliding, and thus indirectly controls the motor to stop driving through the DCU control terminal, resulting in the door not closing properly and causing a safety hazard.

[0087] like Figure 8 and Figure 9 As shown, the top box module 2 is equipped with a door position sensor 22 to monitor the operating status of each individual door. Each individual door has a trigger plate 34 on its top, which is in contact with the door position sensor 22.

[0088] In detail, the position sensor includes a swing arm 221, the end of which is movably connected to a trigger plate 34. In its initial position, the swing arm is perpendicular to the surface of the trigger plate 34. When the door begins to slide, the sliding potential energy of the door is transferred to the swing arm via the trigger plate 34, causing the swing arm to change from a perpendicular state to an inclined state. This change in the swing arm angle is received by the signal terminal inside the position sensor, which feeds this change back to the DCU control terminal. The DCU control terminal then feeds this back to the platform control system, which analyzes the data to determine whether each door is sliding or has stopped. It should be understood that when the swing arm angle is inclined, the door is sliding; when the swing arm angle is perpendicular, the door has stopped sliding.

[0089] This design, through the movable connection between the swing arm and the trigger plate 34, utilizes the potential energy of the sliding door to drive the angle change of the swing arm (from vertical to tilt), which can accurately capture the dynamic state of the door. This allows the signal end of the position sensor to clearly distinguish between the two states of the door "sliding" and "stopped sliding," providing accurate status feedback to the DCU control end and the platform control system, ensuring that the system can monitor the door's movement in real time. Compared with non-contact monitoring, this mechanically triggered angle change monitoring method is less susceptible to environmental interference and has higher stability. Moreover, the structure of the swing arm and the trigger plate 34 is simple and the response is sensitive, which can quickly convert the door's state into a recognizable signal, ensuring the timeliness and accuracy of the judgment of the door's sliding state. This provides a reliable basis for the precise control and safe operation of the door, reducing door control deviations or safety hazards caused by status monitoring errors.

[0090] Another type of train platform, such as Figures 1 to 9 As shown, it includes: multiple platform doors of the above type, with each door module 3 arranged continuously along the length of the platform.

[0091] It should be understood that trains are usually very long, and installing only one platform screen door is usually not enough. Therefore, in actual use, multiple platform screen doors are usually installed.

[0092] Once the train has come to a complete stop at the station, the control system sends control commands to the corresponding platform screen doors based on the train's length and the position of each door. Each platform screen door adjusts its opening state according to its corresponding train door position; for example, the front doors of the train correspond to the platform screen doors at the front of the platform, the middle doors to the middle doors, and the rear doors to the rear doors. Working together, all doors ensure that all train doors are aligned with the open platform screen door areas, allowing passengers to board and alight from their respective opening areas. This design solves the problem of a single platform screen door having limited coverage and being unable to accommodate the entire train length. By arranging multiple platform screen doors continuously along the length of the platform, the entire length of the train can be covered, meeting the stopping needs of trains of different lengths. This makes the platform screen door system more practical and complete, improving the overall operational efficiency and safety of the platform.

[0093] Taking a train with three doors as an example, when the train is about to enter the station, the platform control system obtains its train type information (e.g., the width of the train doors is 1.2 meters) through train dispatching signals. The specific workflow is as follows:

[0094] The platform control system first receives the train door position signal and then distributes the signal to three sets of platform doors arranged continuously along the length of the platform, with each set corresponding to one train door.

[0095] The platform control system selects the "opposite sliding opening" mode based on the door position signal. For example, it controls the first door 31 to slide to the right and the second door 32 to slide to the left. The sliding direction and stroke of the two doors are precisely controlled by the independent drive component 21 in the top box module 2 to ensure that the width of the opening channel matches the width of the short wheelbase train door of 1.2 meters.

[0096] Furthermore, while the first door body 31 and the second door body 32 in the first platform screen door are sliding, the first door body 31 and the second door body 32 in the other platform screen doors are also sliding to reveal the other doors of the train.

[0097] During each door's sliding process, the door position sensor 22 inside the top box module 2 monitors the current door's movement status in real time through the trigger plate 34 on the top of each door.

[0098] When multiple sets of platform doors are working simultaneously, each set corresponds to one door of the train: the door of the first carriage is covered by the first platform door, the door of the second carriage is covered by the second set of platform doors, and the door of the third carriage is covered by the third set of platform doors, ultimately achieving precise "door-to-door" docking along the entire length of the train, effectively improving passenger boarding and alighting efficiency.

[0099] In summary, the platform screen door of this technical solution can achieve efficient and convenient installation with the civil engineering structure of the platform, and at the same time, it can match the corresponding width according to the door position of different vehicle models, effectively solving the problem of fixed opening position of existing platform screen doors and inability to flexibly adapt to the door positions of different vehicle models.
