Description

Technical Field

[0001] This utility model relates to the field of shielding door technology, and in particular to a shielding door. Background Technology

[0002] Currently, platform screen doors are used on train, high-speed rail, and subway platforms. By moving the doors horizontally, they effectively block the passage between the platform and the tracks, improving passenger safety while waiting. However, in real-world applications, it's difficult to achieve perfectly flat surfaces; depressions and bumps are inevitable. When the doors encounter these uneven areas during horizontal movement, their direction of movement can easily deviate.

[0003] When the door panels shift, they rub and press against the moving track or surrounding fixed structures, obstructing their movement. This prevents the doors from opening and closing properly, delaying passenger entry and exit. Furthermore, obstructed door movement places additional loads on the motors and other drive equipment that propel the doors. To overcome this resistance, the motors need to output more power, leading to increased energy consumption. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a shielding door, which guides the movement of the door panel by setting a guide component, thereby improving the directional accuracy of the door panel during movement and preventing the door panel from deviating from its position.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A shielding door, comprising,

[0007] A frame, wherein the frame is provided with a storage cavity, and the storage cavity is provided with an opening;

[0008] A drive assembly, the drive assembly being mounted on the rack;

[0009] A doorway, wherein the drive assembly drives the doorway to move so that the doorway moves through the opening into or out of the receiving cavity;

[0010] The guide assembly includes a first guide mechanism and a second guide mechanism. The first guide mechanism is disposed on the frame, and the second guide mechanism is disposed on the gate. The second guide mechanism cooperates with the first guide mechanism to guide the movement of the gate.

[0011] Therefore, by cooperating with the first guide mechanism on the frame, the second guide mechanism on the gate can guide the gate to move in a directional manner, avoiding problems such as deviation or jamming during the movement of the gate. The directional movement of the gate avoids friction and squeezing between the gate and the moving track or surrounding fixed structure, so that the gate can complete the opening and closing actions normally.

[0012] Furthermore, the first guiding mechanism includes a guide rail, which is disposed at the bottom of the storage cavity along the length of the frame; the second guiding mechanism includes a first guide wheel, which is disposed at the bottom of the door panel and is rotatably connected to the guide rail.

[0013] Therefore, through the cooperation of the guide rail and the first guide wheel, the door can be guided to move in a straight line, avoiding movement deviation and jamming, so that the door can smoothly enter or exit the storage cavity through the exit.

[0014] Furthermore, the top of the guide rail is provided with a support surface, and the two sides of the guide rail are provided with limiting surfaces; the wheel surface of the first guide wheel is vertically arranged, and the center of the wheel surface of the first guide wheel is provided with a snap-fit ​​groove, which is arranged around the circumference of the first guide wheel; the snap-fit ​​groove is snapped onto the guide rail, and the bottom wall of the snap-fit ​​groove rolls with the support surface, and the side wall of the snap-fit ​​groove is limited with the limiting surface.

[0015] Therefore, the engagement between the first guide wheel's locking groove and the guide rail can precisely guide the movement direction of the first guide wheel, ensuring that it can only move along the length of the guide rail. This guarantees that the gate connected to the first guide wheel can move stably in the predetermined straight direction.

[0016] Furthermore, the first guiding mechanism also includes a second guiding wheel, which is disposed at the end of the guide rail near the opening; the second guiding mechanism also includes a guide groove, which is disposed at the bottom end of the door panel along the length direction of the door panel, and the guide groove is in rolling connection with the second guiding wheel.

[0017] Therefore, by setting a guide groove at the bottom of the gate and extending the guide groove along the length of the gate, the cooperation between the guide groove and the second guide wheel compensates for the guiding offset of the guide rail and the first guide wheel, which can further reduce the displacement of the gate in the horizontal direction perpendicular to the guide rail, so that the gate moves linearly along the length of the guide rail.

[0018] Furthermore, the guide groove has a downward-facing opening, and the second guide wheel extends into the guide groove through the opening; the wheel surface of the second guide wheel is arranged laterally, and the wheel surface of the second guide wheel rolls in cooperation with the two side walls of the guide groove.

[0019] Therefore, the cooperation between the guide groove and the second guide wheel restricts the movement of the gate in the horizontal direction perpendicular to the guide rail. Even if the gate is subjected to some external force interference, the rolling cooperation between the second guide wheel and the side wall of the guide groove can keep the gate on the correct movement trajectory without significant deviation or shaking.

[0020] Furthermore, at least two first guide wheels are provided, with at least two first guide wheels respectively located at both ends of the gate.

[0021] Therefore, the first guide wheels at both ends are simultaneously subjected to force to guide the gate's movement, preventing the gate from tilting or twisting due to uneven force and ensuring its smooth movement.

[0022] Furthermore, the frame includes a frame and a panel, and the storage cavity is formed within the frame; the drive assembly and the first guide mechanism are both disposed on the frame; the panel is detachably connected to both sides of the frame; the frame is also provided with a first sensor and a second sensor, the first sensor and the second sensor are respectively disposed at both ends of the storage cavity, and are used to detect the position of the door panel.

[0023] Therefore, by using the first and second sensors, the movement of the gate can be limited, ensuring that the gate stops precisely in the designated position and avoiding problems such as collisions caused by excessive movement of the gate.

[0024] Furthermore, the frame is also provided with a support mechanism, the door panel is provided with a limiting groove along its length direction, and the support mechanism is slidably connected in the limiting groove; the limiting groove is provided with limiting inner walls on both sides along its width direction, and the limiting groove is provided with a bottom wall along its height direction, and the limiting inner walls and the bottom wall are both in cooperation with the support mechanism.

[0025] Therefore, when the door panel tends to deviate along its width, the inner walls of the limiting groove on both sides abut against the sides of the support mechanism. When the door panel tends to move upward along its height, the bottom wall of the limiting groove abuts against the bottom of the support mechanism. This abutment generates resistance, restricting the door panel from moving in the width direction and jumping in the height direction, thus providing stable support for the door panel.

[0026] Furthermore, the support mechanism includes a first limiting wheel, a second limiting wheel, and a support wheel. The wheel surfaces of the first limiting wheel and the second limiting wheel are arranged horizontally and roll in cooperation with the inner walls of the limiting on both sides. The support wheel is disposed between the first limiting wheel and the second limiting wheel, and the wheel surface of the support wheel is arranged vertically. The wheel surface of the support wheel rolls in cooperation with the bottom of the limiting groove.

[0027] Therefore, when the door panel tends to deviate in the width direction, the wheel surfaces of both the first and second limiting wheels roll into contact with the side walls of the limiting groove, preventing the door panel from shifting to the side. The support wheels, with their vertically arranged wheel surfaces, prevent the door panel from jumping upwards, ensuring good contact between the first guide wheel at the bottom of the door panel and the guide rail, guaranteeing smooth door panel movement and reducing the risk of component wear and malfunctions caused by unstable movement.

[0028] Furthermore, the drive assembly includes a drive component, a timing belt, and two timing pulleys. The two ends of the timing belt are respectively arranged around the two timing pulleys. The drive component drives the timing belt to move by driving the timing pulleys to rotate. The gate is provided with a connector, which is connected to the timing belt.

[0029] Therefore, the drive assembly, through the cooperation of the synchronous belt and synchronous pulley, can efficiently convert the rotational power of the drive components into the linear movement power of the gate, so that the shielding door can accurately stop at the preset position during the opening and closing process.

[0030] Furthermore, the connector includes two opposing clamping plates, which are respectively located on both sides of the synchronous belt and clamp the synchronous belt; one of the clamping plates is connected to a connecting plate, which is connected to the gate.

[0031] Therefore, the gate is connected to the synchronous belt through connectors, so that the movement of the synchronous belt can be stably transmitted to the gate, avoiding abnormal opening or closing of the shielding door due to unstable power transmission.

[0032] In summary, the shielding door provided by this utility model has the following technical effects:

[0033] This invention guides the movement of the door panel by setting a guide component, which can improve the directional accuracy of the door panel during movement and prevent the door panel from deviating from its movement. This avoids friction and compression between the door panel and the moving track or surrounding fixed structure, allowing the door panel to complete the opening and closing actions normally.

[0046] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0049] See Figures 1 to 3 This utility model discloses a shielding door, which includes a frame 10, a drive assembly 40, a door panel 20, and a guide assembly 30. Specifically, the frame 10 has a receiving cavity 11, and the receiving cavity 11 has an opening 12; wherein, the drive assembly 40 is mounted on the frame 10 and is used to drive the door panel 20 to move, so that the door panel 20 moves into or out of the receiving cavity 11 through the opening 12. (See reference...) Figure 2 The guide assembly 30 includes a first guide mechanism and a second guide mechanism. Specifically, the first guide mechanism is mounted on the frame 10, and the second guide mechanism is mounted on the gate 20. The second guide mechanism and the first guide mechanism cooperate with each other to guide the gate 20 to move.

[0050] Based on this structure, when using the shielding door of this utility model, during assembly, the first guide mechanism is first installed on the frame 10, and the second guide mechanism is installed on the door panel 20. Then, the assembled door panel 20 and drive assembly 40 are respectively installed into the receiving cavity 11 of the frame 10, and the door panel 20 and drive assembly 40 are connected by transmission, and the first guide mechanism and the second guide mechanism are connected in cooperation.

[0051] In use, the drive assembly 40 is activated first, which transmits power to the gate 20. The gate 20 moves along the guiding direction of the guide assembly 30 and can move horizontally through the opening 12 to enter or extend into the storage cavity 11. When the gate 20 extends out of the storage cavity 11, it can isolate the passage, for example, by separating the station platform from the tracks, to prevent passengers from accidentally falling onto the tracks.

[0052] The second guide mechanism on the gate 20 works in conjunction with the first guide mechanism on the frame 10 to guide the gate 20 to move in a specific direction, thus preventing the gate 20 from deviating or getting stuck during the movement.

[0053] Therefore, the directional movement of the gate 20 avoids friction and compression between the gate 20 and the moving track or surrounding fixed structure, enabling the gate 20 to complete the opening and closing actions normally, greatly reducing the time for passengers to enter and exit the station due to obstruction of the movement of the gate 20, and ensuring the efficient operation of the station.

[0054] Furthermore, since the guide assembly 30 ensures smooth movement of the gate 20, it avoids situations where obstruction of the gate 20's movement would place additional loads on the drive equipment such as the motor. The motor does not need to output more power to overcome the movement resistance, thus reducing energy consumption.

[0055] Further, see Figure 2 as well as Figure 6 The first guiding mechanism includes a guide rail 34, which is disposed at the bottom of the receiving cavity 11 along the length of the frame 10. (See reference...) Figure 4 The second guide mechanism includes a first guide wheel 33, which is located at the bottom of the gate 20 and is rotatably connected to the guide rail 34.

[0056] For details, please refer to Figure 9 The storage cavity 11 has a supporting beam 16 at its bottom, a guide rail 34 is mounted on the supporting beam 16, and both ends of the bottom of the door panel 20 are equipped with first guide wheels 33. (See reference...) Figure 3 and Figure 4 The bottom of the opening 12 is provided with a protective plate 36, and the end of the protective plate 36 is provided with a blocking protrusion. (See also...) Figure 1 When the door panel 20 is stored in the storage cavity 11, the first guide wheel 33 near the opening 12 is positioned on the protective plate 36, and the wheel surface of the first guide wheel 33 abuts against the blocking protrusion, restricting its rolling. (See reference...) Figure 2 and Figure 4 The first guide wheel 33 at the end away from the opening 12 rolls with the guide rail 34, and the first guide wheel 33 at this end has an annular locking groove 331 in the middle of its wheel surface along its circumference, and the locking groove 331 is locked onto the guide rail 34.

[0057] When in use, the protective plate 36 is first removed. As the drive assembly 40 starts and pulls the door panel 20 to move, the first guide wheel 33 near the opening 12 extends out of the opening 12 and rolls with the ground, while the first guide wheel 33 away from the opening 12 rolls on the guide rail 34.

[0058] Therefore, through the cooperation of the guide rail 34 and the first guide wheel 33, the door panel 20 can be guided to move in a straight line, avoiding movement deviation and jamming, so that the door panel 20 can smoothly enter or exit the storage cavity 11 through the outlet. At the same time, the support beam 16 also serves to support the guide rail 34 and the door panel 20. The support beam 16 transmits and distributes the weight of the door panel 20 and the forces it experiences during movement to the frame 10 and the ground, preventing the guide rail 34 from being deformed due to excessive pressure.

[0059] Furthermore, the top of the guide rail 34 is provided with a support surface 341, and both sides of the guide rail 34 are provided with limiting surfaces 342. (See reference...) Figure 2 The first guide wheel 33 has a vertically oriented wheel surface, and a locking groove 331 is provided in the middle of the wheel surface. The locking groove 331 is arranged circumferentially around the first guide wheel 33. The locking groove 331 is engaged with the guide rail 34. Specifically, the bottom of the locking groove 331 rolls with the support surface 341, and the side wall of the locking groove 331 is limited with the limiting surface 342.

[0060] Based on this structure, during assembly, the door panel 20 with the first guide wheel 33 can be installed on the guide rail 34, so that the snap-fit ​​groove 331 of the first guide wheel 33 is aligned with the guide rail 34, and the snap-fit ​​groove 331 is snapped into the guide rail 34, so that the bottom of the snap-fit ​​groove 331 contacts the support surface 341 on the top of the guide rail 34, and the side wall of the snap-fit ​​groove 331 is opposite to the limiting surfaces 342 on both sides of the guide rail 34.

[0061] When the gate 20 moves under the traction of the drive assembly 40, it drives the first guide wheel 33 to move along the direction of the guide rail 34. Since the wheel surface of the first guide wheel 33 is vertically oriented and the engaging groove 331 is arranged circumferentially around the first guide wheel 33, the first guide wheel 33 rolls during movement by engaging the engaging groove 331 with the guide rail 34. The bottom of the engaging groove 331 rolls on the support surface 341 of the guide rail 34, providing rolling and support for the first guide wheel 33, allowing it to move smoothly along the length of the guide rail 34.

[0062] During the movement of the first guide wheel 33, the side wall of the snap-fit ​​groove 331 interacts with the limiting surfaces 342 on both sides of the guide rail 34, restricting the first guide wheel 33 from moving to both sides, so that the first guide wheel 33 can only move within the range defined by the guide rail 34, ensuring that the first guide wheel 33 will not deviate, thereby restricting the displacement of the gate 20 in its width direction.

[0063] Therefore, the engagement between the locking groove 331 of the first guide wheel 33 and the guide rail 34 can precisely guide the movement direction of the first guide wheel 33, so that it can only move along the length direction of the guide rail 34. This ensures that the gate 20 connected to the first guide wheel 33 can move stably in the predetermined straight direction.

[0064] Further, see Figure 6 The first guiding mechanism also includes a second guide wheel 31, which is disposed at the end of the guide rail 34 near the opening 12. (See reference...) Figure 5 The second guiding mechanism also includes a guide groove 32, which is located at the bottom of the door panel 20 along the length of the door panel 20 and above the first guide wheel 33. The guide groove 32 is tactilely connected to the second guide wheel 31.

[0065] Based on this structure, during assembly, the second guide wheel 31 can first be mounted on the frame 10 via the mounting bracket 35. Specifically, both ends of the mounting bracket 35 can be mounted on the support beam 16 using fasteners such as screws and bolts, and the second guide wheel 31 is rotatably mounted on the mounting bracket 35. The second guide wheel 31 and the mounting bracket 35 are located at the end of the guide rail 34 near the opening 12 of the storage cavity 11, with the second guide wheel 31 positioned above the guide rail 34. Then, the door panel 20 is installed into the storage cavity 11, with the first guide wheel 33 of the door panel 20 connected to the guide rail 34, and the second guide wheel 31 embedded in the guide groove 32.

[0066] In use, as the door panel 20 moves, the locking groove 331 of the first guide wheel 33 rolls and is supported on the guide rail 34, while the second guide wheel 31 rolls within the guide groove 32. It should be noted that the second guide wheel 31 is located at the end of the guide rail 34 near the opening 12. When the door panel 20 moves into or out of the storage cavity 11, the second guide wheel 31 interacts with the inner wall of the guide groove 32. The second guide wheel 31 applies force to the door panel 20 through the guide groove 32, guiding the door panel 20 to move in a straight line.

[0067] The guide rail 34 provides lateral constraint to the locking groove 331 of the first guide wheel 33, preventing the door panel 20 from having excessive displacement in the horizontal direction perpendicular to the guide rail 34, and ensuring that the door panel 20 moves linearly along the length of the guide rail 34. It should be noted that, to avoid the locking groove 331 of the first guide wheel 33 from jamming with the guide rail 34, the width of the locking groove 331 is usually set to be relatively large, which will cause the door panel 20 to have a certain displacement in the horizontal direction perpendicular to the guide rail 34.

[0068] Therefore, by providing a guide groove 32 at the bottom of the door panel 20 and extending the guide groove 32 along the length direction of the door panel 20, the cooperation between the guide groove 32 and the second guide wheel 31 compensates for the guiding offset of the guide rail 34 and the first guide wheel 33, which can further reduce the displacement of the door panel 20 in the horizontal direction perpendicular to the guide rail 34, so that the door panel 20 moves linearly along the length direction of the guide rail 34.

[0069] Thus, the two sets of guide structures complement each other and work together to maintain the moving direction of the gate 20, greatly enhancing the stability of the platform screen door operation.

[0070] Further, see Figure 5 as well as Figure 9 The guide groove 32 has a downward-facing opening, and the second guide wheel 31 extends into the guide groove 32 through the opening. The wheel surface of the second guide wheel 31 is arranged laterally, and the wheel surface of the second guide wheel 31 rolls in contact with the two side walls of the guide groove 32.

[0071] Based on this structure, during assembly, the guide groove 32 is first installed at the bottom of the door panel 20 and above the first guide wheel 33, ensuring that the groove opening of the guide groove 32 faces downward. Then, the second guide wheel 31 is installed at the end of the guide rail 34 near the opening 12 and its wheel surface is set horizontally. Then, it extends into the guide groove 32 through the groove opening.

[0072] When the gate panel 20 begins to move, the first guide wheel 33 rolls along the guide rail 34, causing the gate panel 20 to move as a whole. At the same time, the second guide wheel 31 rolls within the guide groove 32. Since the wheel surface of the second guide wheel 31 is arranged laterally, it contacts the two side walls of the guide groove 32 and begins to roll.

[0073] Therefore, the cooperation between the guide groove 32 and the second guide wheel 31 restricts the movement of the gate 20 in the horizontal direction perpendicular to the guide rail 34. Even if the gate 20 is subjected to some external force interference, the rolling cooperation between the second guide wheel 31 and the side wall of the guide groove 32 can keep the gate 20 on the correct movement trajectory without significant deviation or shaking.

[0074] In this way, the first guide wheel 33, through its vertical wheel surface and engaging groove 331, engages with the guide rail 34, guiding the gate panel 20 to move linearly along the length of the guide rail 34 and limiting its deviation in the horizontal direction perpendicular to the guide rail 34. Meanwhile, the second guide wheel 31, through its transverse wheel surface, engages with the guide groove 32, ensuring that even if the guide groove 32 is narrow, there will be no jamming between the guide groove 32 and the second guide wheel 31, further providing constraint in the horizontal direction perpendicular to the guide rail 34. The combined action of the first and second guiding mechanisms improves the directional accuracy of the gate panel 20 during movement.

[0075] Further, see again Figure 6 At least two first guide wheels 33 are provided, and at least two first guide wheels 33 are respectively provided at both ends of the gate 20.

[0076] Based on this structure, when the drive assembly 40 is activated and moves the gate 20, the first guide wheels 33 located at both ends of the gate 20 roll on the support surface 341 of the guide rail 34 via vertically arranged wheel surfaces, jointly maintaining the gate 20's linear movement along the length direction of the guide rail 34 from both ends. Simultaneously, the guide groove 32 closely cooperates with the second guide wheel 31 rolling within it, and the second guide wheel 31 adjusts the gate 20's movement posture in real time according to the extension direction of the guide groove 32.

[0077] Therefore, the first guide wheels 33 at both ends are simultaneously subjected to force to guide the movement of the gate 20, preventing the gate 20 from tilting or twisting due to uneven force and ensuring its smooth movement. The guide groove 32 serves as the constraint path for the second guide wheel 31. When the gate 20 is affected by external forces, the second guide wheel 31 can adjust in time through the guide groove 32, further enhancing the stability of the gate 20's movement.

[0078] Further, see Figure 3 The frame 10 includes a frame 15 and a panel 13, and a receiving cavity 11 is formed within the frame 15. Specifically, the drive assembly 40 and the first guide mechanism are both disposed on the frame 15, and the panel 13 is detachably connected to both sides of the frame 15. See also... Figure 8 The frame 15 is also provided with a first sensor 60 and a second sensor 80, and the first sensor 60 and the second sensor 80 are respectively located at both ends of the storage cavity 11 and are used to detect the position of the door panel 20.

[0079] Based on this structure, during assembly, the drive assembly 40, the first guide mechanism, the first sensor 60, and the second sensor 80 are first connected to the frame 15. Then, the door panel 20 is installed into the storage cavity 11, and the door panel 20 is connected to the drive assembly 40 for transmission. Next, the second guide mechanism on the door panel 20 is connected to the second guide mechanism. Subsequently, the panel 13 is detachably installed on both sides of the frame 15 to cover both sides of the storage cavity 11. In use, the drive assembly 40 is activated to move the door panel 20 along the guide rail 34 of the first guide mechanism. During movement, the first sensor 60 and the second sensor 80 can detect the position of the door panel 20.

[0080] The first sensor 60 and the second sensor 80 can both be infrared sensors, photoelectric switch sensors, etc., in the prior art.

[0081] Specifically, if the door panel 20 moves outward from the storage cavity 11, the first sensor 60, upon sensing the door panel 20, will transmit a signal to the control system to stop the drive assembly 40 from moving the door panel 20 outward. Similarly, if the door panel 20 moves inward into the storage cavity 11 to the other end, the second sensor 80, upon sensing the door panel 20, will transmit a signal to the control system to stop the drive assembly 40 from moving the door panel 20 inward.

[0082] Therefore, by using the first sensor 60 and the second sensor 80, the movement of the gate 20 can be limited, ensuring that the gate 20 stops precisely at the designated position, thus avoiding problems such as collisions caused by excessive movement of the gate 20.

[0083] It should be noted that the panel 13 in this embodiment can be an advertising board, a guide board, etc. By installing the advertising panel 13 with advertisements or the guide panel 13 with information such as travel information and map routes on both sides of the frame 15, commercial value can be brought to the platform space and convenience can be provided to passengers.

[0084] The panel 13 can be detachably connected to the side of the frame 15 via a snap-on or magnetic structure, making it easy to remove the panel 13 for inspection and maintenance of the inside of the rack 10. It can also update the advertising information and guidance information on the panel 13.

[0085] In addition, the frame 10 also includes a cover plate 14, which is detachably installed on the top of the frame 15 by means of screws or clips. In this way, the sides and top of the frame 15 can be sealed by the side panels 13 and the cover plate 14 to prevent external rainwater from seeping into the storage cavity 11 and damaging the drive assembly 40.

[0086] Further, see Figure 6 The frame 15 also has a support structure 70, see reference. Figure 5 The gate panel 20 has a limiting groove 21 along its length, and the support mechanism 70 is slidably connected within the limiting groove 21. For details, please refer to... Figure 9 The limiting groove 21 has limiting inner walls on both sides along its width direction and a bottom wall at the bottom along its height direction. Both limiting inner walls and the bottom wall cooperate with the support mechanism 70.

[0087] Thus, during the movement of the door panel 20, the limiting groove 21 slides relative to the support mechanism 70, and the support mechanism 70 does not obstruct the normal movement of the door panel 20. When the door panel 20 tends to deviate along its width direction, the inner walls of the limiting groove 21 on both sides abut against the sides of the support mechanism 70. When the door panel 20 tends to move upward along its height direction, the bottom wall of the limiting groove 21 abuts against the bottom of the support mechanism 70. This abutment generates resistance, limiting the door panel 20's movement in the width direction and its jumping in the height direction, thus providing stable support for the door panel 20.

[0088] Further, see Figure 6 The support mechanism 70 includes a first limiting wheel 71, a second limiting wheel 72, and a support wheel 73. Specifically, the wheel surfaces of the first limiting wheel 71 and the second limiting wheel 72 are arranged horizontally and roll in cooperation with the inner walls of the limiting groove 21 along both sides of its width. The support wheel 73 is disposed between the first limiting wheel 71 and the second limiting wheel 72, and the wheel surface of the support wheel 73 is arranged vertically and rolls in cooperation with the bottom of the limiting groove 21.

[0089] Based on this structure, during assembly, the bracket 74 can first be welded to the frame 15, and then the support mechanism 70 can be installed on the bracket 74. The first limiting wheel 71, the second limiting wheel 72, and the support wheel 73 can all rotate on the bracket 74. After the door panel 20 is installed into the storage cavity 11, the first limiting wheel 71, the second limiting wheel 72, and the support wheel 73 are fitted into the limiting groove 21.

[0090] When the door panel 20 is moving, the support wheel 73 can roll and engage with the bottom wall of the limiting groove 21 within the limiting groove 21 through its vertically arranged wheel surface. When the door panel 20 tends to deviate in the width direction, the wheel surfaces of the first limiting wheel 71 and the second limiting wheel 72 roll and engage with the side walls of the limiting groove 21 on both sides, which can prevent the door panel 20 from deviating to the side.

[0091] In addition, the support wheel 73, with its vertically arranged wheel surface, can prevent the gate 20 from jumping, so that the first guide wheel 33 at the bottom of the gate 20 can make good contact with the guide rail 34, ensuring the smooth movement of the gate 20 and reducing the risk of component wear and failure caused by unstable movement.

[0092] Further, see Figure 7 The drive assembly 40 specifically includes a drive element 43, a timing belt 41, and two timing pulleys 42. The two ends of the timing belt 41 are respectively arranged around the two timing pulleys 42, and the drive element 43 drives the timing belt 41 to move by rotating the timing pulleys 42. Furthermore, see [reference needed]. Figure 4 and Figure 5 The gate 20 is provided with a connector 50, and the connector 50 is connected to the synchronous belt 41.

[0093] Based on this structure, during assembly, two synchronous pulleys 42 can be installed horizontally at intervals on the frame 10, and then the two ends of the synchronous belt 41 are respectively wrapped around the outside of the two synchronous pulleys 42. Then, the drive unit 43 is installed on the frame 10 and connected to one of the synchronous pulleys 42 for transmission.

[0094] In operation, the drive unit 43 (such as a motor) starts running and transmits its rotational power to the synchronous pulley 42, causing the synchronous pulley 42 to rotate. Since the two ends of the synchronous belt 41 are respectively wrapped around the two synchronous pulleys 42, the synchronous belt 41 is driven to move linearly as the synchronous pulleys 42 rotate. The connecting piece 50 on the gate panel 20 is connected to the synchronous belt 41, so the linear movement of the synchronous belt 41 is transmitted to the gate panel 20 through the connecting piece 50, thereby driving the gate panel 20 to move horizontally along the guide rail 34, realizing the opening and closing of the shielded door.

[0095] Thus, through the cooperation of the timing belt 41 and the timing pulley 42, the drive assembly 40 can efficiently convert the rotational power of the drive component 43 into the linear movement power of the gate 20, so that the shielding door can accurately stop at the preset position during the opening and closing process.

[0096] Furthermore, the outer circumference of the synchronous pulley 42 is provided with a first meshing tooth, and the inner side of the synchronous belt 41 is provided with a second meshing tooth. The synchronous belt 41 and the synchronous pulley 42 are connected through the second meshing tooth and the first meshing tooth. Thus, through the meshing transmission method, slippage between the synchronous pulley 42 and the synchronous belt 41 can be prevented, power can be transmitted more accurately, energy loss can be reduced, and the rapid response and stable operation of the platform screen door can be guaranteed.

[0097] Further, see Figure 4 as well as Figure 10 The connector 50 includes two opposing clamping plates 52, which are located on both sides of the timing belt 41 and clamp the timing belt 41. (See reference...) Figure 5 One of the clamps 52 is connected to a connecting plate 51, and the connecting plate 51 is connected to the door panel 20.

[0098] Based on this structure, during assembly, two opposing clamping plates 52 can be placed on both sides of the timing belt 41, and then the clamping plates 52 can be fixed with bolts, nuts and other fastening components to tightly clamp the timing belt 41. Next, one of the clamping plates 52 connected to the connecting plate 51 is connected to the gate 20.

[0099] When the platform screen door opens or closes, the synchronous belt 41 begins to move under the drive of the synchronous pulley 42. Since the two clamping plates 52 tightly hold the synchronous belt 41, the movement of the synchronous belt 41 causes the clamping plates 52 to move as well. The connecting plate 51, connected to the clamping plates 52, moves accordingly, thereby transmitting the moving force of the synchronous belt 41 to the door panel 20, driving the door panel 20 to move horizontally along the guide rail 34, thus realizing the opening or closing action of the platform screen door.

[0100] Therefore, the gate 20 is connected to the synchronous belt 41 via the connector 50, so that the movement of the synchronous belt 41 can be stably transmitted to the gate 20, avoiding abnormal opening or closing of the shielding door due to unstable power transmission. A third meshing tooth can be provided on the side of the clamp 52 facing the synchronous belt 41, and the third meshing tooth connects with the second meshing tooth. This provides the clamp 52 with greater friction, ensuring that slippage does not occur between the synchronous belt 41 and the clamp 52.
