The smoothness of the sliding mechanism directly affects the force required to slide the door leaf. Currently, most bearings are roller or needle roller bearings, which generate direct vibration and noise during the sliding process on the door frame track. Furthermore, the heavy door leaf is difficult to slide, resulting in a poor user experience. Utility Model Content

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0030] See Figure 1-6 This embodiment discloses a door and window, including a frame 2, a sash 3 and a magnetic load-bearing device 1. The magnetic load-bearing device 1 is located between the frame 2 and the sash 3 to realize the magnetic levitation connection between the frame 2 and the sash 3, which can ensure that the load-bearing slider 20 slides without friction, thereby reducing noise and facilitating pushing and pulling.
[0031] Specifically, the track structure 10 mounted on the frame includes a track rod 11 and a track support 12, with the track rod 11 connected to the track support 12. The magnetic load-bearing device 1 includes a load-bearing slider 20 connected to the fan body 3. The load-bearing slider 20 includes a fan body connecting plate 23, a magnet assembly 22, and a guide friction plate 25. One side of the fan body connecting plate 23 is connected to the fan body 3, and the other side is connected to the magnet assembly 22 and the guide friction plate 25. The magnet assembly 22 attracts the track rod 11, and the guide friction plate 25 abuts against the track structure 10 to prevent the magnet assembly 22 from contacting the track structure 10 to form magnetic levitation. The track support 12 is made of a magnetically conductive material, and a magnetic flux is formed between the magnet assembly 22, the track rod 11, and the track support 12. By making the track support 12 a magnetically conductive material, a magnetic flux is formed between the magnet assembly 22, the track rod 11, and the track support 12, enhancing the magnetism and making it more suitable for heavy-duty fan bodies 3.
[0032] The track rod 11 can be square or round. The shape of the track support 12 can be adjusted according to the shape of the track rod 11. For ease of installation, the track rod 11 and the track support 12 can also be designed as a single integral structure.
[0033] It should be noted that the magnetic suction load-bearing device 1 in this solution is divided into a single-track magnetic suction load-bearing device 1 and a double-track magnetic suction load-bearing device 1.
[0034] The track support 12 in the monorail magnetic load-bearing device 1 is T-shaped, with a track rod 11 in the middle. The load-bearing slider 20 includes two sets of magnet assemblies 22 and two sets of guide members. The two sets of magnet assemblies 22 are respectively located on both sides of the track rod 11, and the two sets of guide members abut against both sides of the track rod 11.
[0035] In the dual-track magnetic load-bearing device 1, the track support 12 is a U-shaped support, with two track rods 11 respectively located on both sides of the track support 12. The magnet assembly 22 is inserted between the two track rods 11, and a guide member is located in the middle of the magnet assembly 22 to abut against the track rod 11; or, at least two guide members are respectively located at both ends of the magnet assembly 22 to abut against the track rod 11. This embodiment uses the dual-track magnetic load-bearing device 1 as an example for detailed explanation.
[0036] See Figure 4-6 The load-bearing slider 20 also includes a fan body connecting plate 23. One side of the fan body connecting plate 23 is connected to the fan body 3, and the other side of the fan body connecting plate 23 is connected to the magnet assembly 22. The fan body connecting plate 23 is made of non-magnetic material.
[0037] In this embodiment, the magnet assembly 22 includes a magnet component and a protective shell 225. The protective shell 225 covers the magnet component and is connected to the fan body 3.
[0038] In this embodiment, the magnet component includes a first magnet 221, a second magnet 222, and a magnetic conductor 223. The magnet assembly 22 is composed of the first magnet 221, the second magnet 222, and the magnetic conductor 223. Placing the magnetic conductor 223 between the first magnet 221 and the second magnet 222 enhances the magnetism, which can accommodate heavier mobile fans while also saving costs. The south pole of the first magnet 221 is in the same direction as the south pole of the second magnet 222, and the north pole of the first magnet 221 is in the same direction as the north pole of the second magnet 222. Specifically, the magnetic conductor 223 is positioned between the first magnet 221 and the second magnet 222 along the magnetic field direction of the first magnet 221 and the second magnet 222.
[0039] In this embodiment, the length of the magnetic conductor 223 is greater than or equal to the length of the first magnet 221 and the second magnet 222 to ensure that the magnetic conductor 223 can comprehensively enhance the magnetic field. Specifically, the lengths of the magnetic conductor 223, the first magnet 221, and the second magnet 222 are the same. The thickness of the magnetic conductor 223 is less than or equal to the thickness of the first magnet 221 and the second magnet 222. The best magnetic conduction effect is achieved when the thickness of the first magnet 221 is the same as the thickness of the second magnet 222 and is twice the thickness of the magnetic conductor 223. The height of the magnetic conductor 223 is greater than or equal to the height of the first magnet 221 and the second magnet 222, with the height of the magnetic conductor 223 being equal to the height of the first magnet 221 and the second magnet 222, which saves the most material. In actual production, the first magnet 221 and the second magnet 222 can be selected with the same structure for convenient processing and installation.
[0040] In this embodiment, the load-bearing slider 20 also includes an overload friction plate 26, which is connected to the other side of the fan body connecting plate 23. The overload friction plate 26 is used to contact the track structure 10 under extreme conditions to prevent the fan body connecting plate 23 from contacting the track structure 10. The guide friction plate 25 and the overload friction plate 26 are integrally formed. The overload friction plate 26 and the guide friction plate 25 are integrally formed, with an overall L-shape. The horizontal portion is located at the bottom of the fan body connecting plate 23, and the vertical portion is located on the side wall of the magnet assembly 22. This ensures that the track rod 11 will not contact either the fan body connecting plate 23 or the magnet assembly 22, resulting in low manufacturing cost and easy installation.
[0041] In another embodiment, the overload friction plate 26 can be replaced by an overload load-bearing wheel, which protrudes from the other side of the fan body connecting plate 23 and is used to contact the track structure 10 under extreme conditions to prevent the fan body connecting plate 23 from contacting the track structure 10. Under normal circumstances, the magnetism of the magnet assembly 22 matches the mass of the fan body 3, and the overload load-bearing wheel is not used. It is only necessary to use the overload load-bearing wheel under special extreme conditions.
[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
