Abstract
Description
Technical Field
[0001] This utility model belongs to the field of magnetic levitation sliding door technology, and specifically relates to a magnetic levitation sliding door. Background Technology
[0002] As architectural and home design increasingly demand functionality and aesthetics, traditional sliding doors that rely on pulleys and tracks for sliding are no longer able to meet the needs of high-end applications due to issues such as high friction, noise during operation, and severe wear and tear after long-term use.
[0003] To address the aforementioned issues, the industry has proposed magnetic levitation sliding door technology. This technology utilizes the principle of repulsion between like poles of magnets to generate a repulsive force between the door and the track, causing the door to levitate above the track, thus achieving smooth, contactless movement. Some existing magnetic levitation door designs typically incorporate a magnetic levitation component at the bottom of the door to provide upward support, and guide components on the sides or top of the door to prevent wobbling, thus achieving stable movement. However, existing technology still has the following drawbacks: when such magnetic levitation sliding doors are applied to environments where they may come into contact with water, such as balconies, courtyards, or bathrooms, water easily accumulates in the bottom track or frame. This accumulated water is difficult to drain, which not only corrodes the internal metal components, affecting the performance and lifespan of the magnetic levitation system, but may also breed bacteria, posing hygiene hazards. Utility Model Content

The lower magnetic levitation assembly includes a lower fixed magnet and a lower movable magnet that cooperate with each other to generate magnetic repulsion. They are respectively disposed at the bottom of the bottom frame and the bottom of the door panel assembly, and are used to support the door panel assembly through magnetic repulsion, so that it is in a non-contact levitation state with the bottom frame. An upper magnetic guide assembly is disposed between the top of the door panel assembly and the top frame. The upper magnetic guide assembly includes an upper fixed magnet and an upper movable magnet that cooperate with each other to generate a magnetic force. The upper fixed magnet and the upper movable magnet are respectively disposed on the top of the top frame and the top of the door panel assembly, and are used to provide non-contact lateral stability when the door panel assembly moves. A drainage channel is provided within the bottom frame, and a flushing device is provided at one end of the drainage channel. The drainage channel is used to drain the water accumulated within the bottom frame.
[0006] To better realize this utility model, further optimizations are made to the above structure. The bottom frame is an integrally formed extruded profile, and the drainage channel is a cavity integrated inside the extruded profile. The output end of the flushing device is connected to the through hole at the end of the drainage channel.
[0007] To better realize this utility model, further optimizations are made to the above structure: the top surface of the bottom frame is provided with a water inlet hole communicating with the drainage channel; the bottom frame is configured to have a preset slope along its length.
[0008] To better realize this utility model, further optimizations are made to the above structure. The drainage channel extends along the length of the bottom frame, the outlet of the drainage channel is lower than its inlet, and the water in the drainage channel can flow out under the action of gravity.
[0009] To better realize this utility model, further optimizations are made to the above structure. The lower fixed magnet is a lower permanent magnet guide wheel fixed in the bottom frame; the lower movable magnet is a lower permanent magnet rail fixed to the bottom of the door panel assembly, and the lower permanent magnet rail and the lower permanent magnet guide wheel are opposite each other with the same pole.
[0010] To better realize this utility model, the above structure is further optimized. The upper fixed magnet is an upper permanent magnet guide wheel; the upper movable magnet is an upper permanent magnet rail. The upper permanent magnet guide wheel and the upper permanent magnet rail cooperate with each other to provide the lateral stability.
[0011] To better realize this utility model, the above structure is further optimized, and both the lower fixed magnet and the lower movable magnet are elongated magnets; Both the upper fixed magnet and the upper movable magnet are elongated strip magnets.
[0012] To better realize this utility model, further optimizations are made to the above structure. The door panel assembly includes insulated glass, and I-shaped glass base and I-shaped glass top seat for fixing the bottom and top of the insulated glass, respectively.
[0013] To better realize this utility model, further optimizations are made to the above structure. The magnetic levitation moving door also includes a detachable cover plate disposed at the bottom or top of the door panel assembly for maintenance of the lower magnetic levitation assembly or the upper magnetic guide assembly.
[0014] Compared with the prior art, this utility model has the following advantages: This utility model provides a magnetic levitation sliding door, comprising: A fixed frame component, the frame component including a bottom frame and a top frame; A movable door panel assembly, the door panel assembly being movably disposed within the frame assembly; Also includes: The lower magnetic levitation assembly is disposed between the bottom of the door panel assembly and the bottom frame. The lower magnetic levitation assembly includes a lower fixed magnet and a lower movable magnet that cooperate with each other to generate magnetic repulsion. They are respectively disposed at the bottom of the bottom frame and the bottom of the door panel assembly, and are used to support the door panel assembly through magnetic repulsion, so that it is in a non-contact levitation state with the bottom frame. An upper magnetic guide assembly is disposed between the top of the door panel assembly and the top frame.

A drainage channel is provided within the bottom frame, and a flushing device is provided at one end of the drainage channel. The drainage channel is used to drain the water that enters the bottom frame.
[0015] The above structure ensures smooth and quiet operation and a long lifespan. The lower magnetic levitation assembly supports the door, while the upper magnetic guide assembly provides non-contact guidance, completely eliminating physical friction between the door and frame. This results in extremely smooth and virtually noiseless sliding door operation, fundamentally preventing component wear and significantly extending its service life. It also effectively solves the problem of water accumulation, improving durability. An innovative drainage channel within the bottom frame, with a flushing device at its end, cleans the bottom frame while simultaneously draining rainwater or cleaning water. This effectively prevents corrosion and damage to internal metal components, ensuring long-term stable operation of the magnetic levitation system in humid environments and improving the overall durability and hygiene of the device.

[0022] Example 1: A magnetically levitated moving door includes: a fixed frame assembly, the frame assembly including a bottom frame 10 and a top frame 12; A movable door panel assembly, the door panel assembly being movably disposed within the frame assembly; Also includes: The lower magnetic levitation assembly is disposed between the bottom of the door panel assembly and the bottom frame 10. The lower magnetic levitation assembly includes a lower fixed magnet 1 and a lower movable magnet 2 that cooperate with each other to generate magnetic repulsion. They are respectively disposed at the bottom of the bottom frame 10 and the bottom of the door panel assembly, and are used to support the door panel assembly through magnetic repulsion, so that it is in a non-contact levitation state with the bottom frame 10. An upper magnetic guide assembly is disposed between the top of the door panel assembly and the top frame 12. The upper magnetic guide assembly includes an upper fixed magnet 3 and an upper movable magnet 4 that cooperate with each other to generate a magnetic force. They are respectively disposed on the top of the top frame 12 and the top of the door panel assembly, and are used to provide non-contact lateral stability when the door panel assembly moves. A drainage channel 5 is provided inside the bottom frame 10, and a flushing device 6 is provided at one end of the drainage channel 5. The drainage channel 5 is used to drain the water that enters the bottom frame 10.
[0023] The aforementioned structure ensures smooth and quiet operation and a long lifespan. The lower magnetic levitation assembly supports the door, while the upper magnetic guide assembly provides non-contact guidance, completely eliminating physical friction between the door and frame. This results in extremely smooth and virtually noiseless sliding door operation, fundamentally preventing component wear and significantly extending its lifespan. It effectively solves the problem of water accumulation and improves durability. An innovative drainage channel 5 is installed within the bottom frame 10, with a flushing device 6 at the end of the drainage channel 5. This cleans the bottom frame 10 while simultaneously draining rainwater or cleaning water, effectively preventing corrosion and damage to internal metal components. This ensures the long-term stable operation of the magnetic levitation system in humid environments, improving the overall durability and hygiene of the device. The flushing device 6 is a commercially available water pump. The pump's action flushes the drainage channel 5, cleaning it and draining any accumulated water. The bottom frame 10 is a one-piece extruded profile, and the drainage channel 5 is a cavity integrated inside the extruded profile; the output end of the flushing device 6 is connected to the through hole at the end of the drainage channel 5. The bottom frame 10 profile is made of corrosion-resistant metal materials such as aluminum alloy and is manufactured in one piece through an extrusion process. When designing the extrusion die, one or more closed or semi-closed cavities have been pre-designed in the internal structure of the profile, and these cavities directly constitute the integrated drainage channel 5. This design integrates the drainage function with the load-bearing and positioning functions of the frame into the same component.
[0024] The bottom frame 10 has a water inlet hole on its top surface that communicates with the drainage channel 5; the bottom frame 10 is configured with a preset slope along its length. To achieve automatic and reliable water drainage, the entire bottom frame 10 profile is installed with a small but effective preset slope along its length, for example, 0.5% to 1%, meaning one end of the frame is slightly higher than the other. Thus, under gravity, all water entering the integrated drainage channel 5 through the water inlet hole will automatically flow to the lower end. At the lowest point of the profile, a drainage hole is pre-drilled on its end wall, which is connected to a pre-embedded drainage pipe in the building via a sealing joint. Therefore, the collected water can be smoothly drained without lingering inside the frame.
[0025] The drainage channel extends along the length of the bottom frame 10, with its outlet lower than its inlet, allowing water to flow out under gravity. This embodiment offers significant advantages. First, it boasts high production efficiency and low cost, as the mature aluminum alloy extrusion process allows for the mass production of profiles with complex cross-sections at low cost. Second, it features high structural integration and a simpler, more aesthetically pleasing appearance, as the drainage channel is completely concealed within the profile, with no unnecessary external components. Third, it exhibits excellent corrosion resistance, as aluminum alloy itself possesses superior corrosion resistance, making it ideal for use in humid environments.
[0026] The lower fixed magnet 1 is a lower permanent magnet guide wheel 11 fixed within the bottom frame 10; the lower movable magnet 2 is a lower permanent magnet rail fixed to the bottom of the door panel assembly, with the lower permanent magnet rail and the lower permanent magnet guide wheel having the same pole opposite each other. The lower fixed magnet 1 can be a lower permanent magnet stainless steel guide wheel fixedly installed along the door's moving path. A lower frame of the sliding door contour is fixed inside the bottom fixed shell, providing a mounting base for the magnetic components. To accurately position and support the lower permanent magnet stainless steel guide wheel, a strip-shaped support block is also fixed inside the lower frame of the sliding door contour. The lower permanent magnet stainless steel guide wheels are mounted on the top surface of the strip-shaped support block and are arranged linearly along the door's moving direction. It is understood that these guide wheels can use high-performance permanent magnets (such as sintered NdFeB magnets) as their core and be encased in a stainless steel shell to prevent magnet corrosion and wear. During installation, the magnetic pole directions of all lower permanent magnet stainless steel guide wheels are kept uniform; for example, all their N poles face upwards.
[0027] Preferably, the combination of the lower permanent magnet guide wheel 11 and the bottom frame 10 is in two sets, with the two sets of lower permanent magnet guide wheels 11 and the bottom frame 10 arranged side by side, which improves the stability of the door panel assembly. Furthermore, the use of two sets of lower permanent magnet guide wheels 11 and the bottom frame 10 can be applied to narrower door panel assemblies, increasing the application scenarios of the magnetic levitation sliding door.
[0028] In conjunction with the lower fixed magnet 1, the lower movable magnet 2 serves as a lower permanent magnet rail fixed to the bottom of the door panel assembly. This lower permanent magnet rail is mounted on the lower surface of the I-shaped glass base 8, its position precisely corresponding to the lower permanent magnet stainless steel guide wheel below. The structure of the lower permanent magnet rail is similar to that of the lower permanent magnet stainless steel guide wheel, also incorporating high-performance permanent magnets, but its magnetic pole direction is opposite to that of the lower permanent magnet stainless steel guide wheel; for example, its N pole faces downwards. Thus, when the door panel assembly is installed, the lower permanent magnet rail is directly above the lower permanent magnet stainless steel guide wheel, and their identical magnetic poles (N pole to N pole) approach each other, generating a strong magnetic repulsion force. This repulsion force is precisely designed to overcome the weight of the entire door panel assembly, thereby lifting the door panel assembly upwards and suspending it approximately 3-5 millimeters above the bottom frame 10, achieving a non-physical contact suspension support.
[0029] The upper fixed magnet 3 is an upper permanent magnet guide wheel; the upper movable magnet 4 is an upper permanent magnet rail. The upper permanent magnet guide wheel and the upper permanent magnet rail cooperate to provide lateral stability. The upper magnetic guide assembly is used to provide lateral stability through non-contact magnetic force when the door panel assembly moves, to prevent the door panel assembly from swaying or tilting back and forth, and to ensure that it slides smoothly along a predetermined trajectory. The upper magnetic guide assembly includes an upper fixed magnet 3 and an upper movable magnet 4 that cooperate with each other. A repulsive force is generated between the sides of the upper permanent magnet stainless steel guide wheel and the permanent magnet stainless steel rail, thereby constraining the top of the door panel assembly to the central position. When the door panel assembly is subjected to lateral disturbance (such as a slight push or airflow), the gap on one side decreases, and the magnetic repulsive force increases accordingly, while the gap on the other side increases, and the magnetic repulsive force decreases. This unbalanced magnetic force will quickly push the door panel assembly back to the central equilibrium position. The entire guiding process is completely non-contact, avoiding the friction and noise between traditional guide wheels and guide rails.
[0030] Example 2: Both the lower fixed magnet 1 and the lower movable magnet 2 are elongated magnets; Both the upper fixed magnet 3 and the upper movable magnet 4 are elongated magnets. Using elongated magnets ensures that both the vertical levitation force and the horizontal guiding force are more evenly distributed across the entire door panel. This helps the door maintain better posture stability during movement, resulting in smoother operation. Simultaneously, eliminating the wheeled rotating components simplifies the structure, reduces potential failure points, and facilitates daily cleaning and maintenance. This design can also be combined with the drainage channel design in Embodiment 1 to achieve equally excellent overall performance.
[0031] The door panel assembly includes a double-glazed glass unit 7, and an I-shaped glass base 8 and an I-shaped glass top mount 9 for securing the bottom and top of the double-glazed glass unit 7, respectively. Specifically, the lower edge of the double-glazed glass unit 7 is tightly embedded in the upper groove of the I-shaped glass base 8, while its upper edge is embedded in the lower groove of the I-shaped glass top mount 9. This I-shaped structure provides a large contact area and structural strength, ensuring that the glass is securely fixed. The I-shaped glass base 8 and the I-shaped glass top mount 9 are typically made of high-strength metal materials (such as aluminum alloy or stainless steel) to support the weight of the entire door panel assembly and resist deformation.
[0032] The magnetic levitation sliding door also includes a removable cover plate disposed at the bottom or top of the door panel assembly for accessing the lower magnetic levitation assembly or the upper magnetic guide assembly. At the bottom of the door panel assembly, a removable plate can be inserted and installed between two adjacent I-shaped glass bases 8. Similarly, at the top of the door panel assembly, a removable plate can be inserted and installed between two adjacent I-shaped glass top bases 9. When maintenance is required, simply removing the removable plate exposes the internal lower magnetic levitation assembly or upper magnetic guide assembly, facilitating operation by technicians without disassembling the entire door leaf, thus greatly improving maintainability.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
