[0029] 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.
[0030] 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.
[0031] See Figure 1-7This embodiment provides 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.
[0032] Specifically, the track structure 10 is connected to the frame 2; the magnetic load-bearing device 1 includes a load-bearing slider 20, which is 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 wheel 21. 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 wheel 21. The magnet assembly 22 attracts the track structure 10, and the guide wheel 21 abuts against the track structure 10 to prevent the magnet assembly 22 from contacting the track structure 10 to form magnetic levitation. The fan body connecting plate 23 is made of magnetically conductive material, and the fan body connecting plate 23 does not contact the track structure 10. By making the fan body connecting plate 23 a magnetically conductive material, a magnetic flux is formed between the fan body connecting plate 23, the magnet assembly 22, and the track structure 10, enhancing the magnetism and making it more suitable for heavy-duty fan bodies 3.
[0033] In this embodiment, the track structure 10 includes a track rod 11 and a track support 12. The track support 12 is connected to the frame 2, and the track rod 11 is supported on the track support 12. The track rod 11 is made of a magnetically conductive material or a magnetic material, while the track support 12 is made of a non-magnetically conductive material. The track rod 11 can be square or circular in shape. 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 an integrally formed structure.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] See Figure 4-6The magnet assembly 22 includes a magnet component, a limiting bracket 224, and a protective shell 225. The limiting bracket 224 has a receiving groove for accommodating the magnet component. The protective shell 225 covers the limiting bracket 224 and is connected to the fan body 3. The protective shell 225 is used to prevent the magnet from being exposed and falling or breaking, and to improve the aesthetics.
[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] See Figure 7The limiting bracket 224 includes a magnetic receiving groove 2241, a first magnet 221 receiving groove, and a second magnet 222 receiving groove (not shown in the figure). The magnetic receiving groove 2241 extends through both ends of the limiting bracket 224, facilitating the insertion of the magnetic conductor 223 from both ends. The opening of the first magnet 221 receiving groove is located on one side of the limiting bracket 224, and the opening of the second magnet 222 receiving groove is located on the other side of the limiting bracket 224. After the magnetic conductor 223 is inserted, the first magnet 221 and the second magnet 222 can be stably installed in the first magnet 221 receiving groove and the second magnet 222 receiving groove, respectively, due to the magnetic attraction with the magnetic conductor 223. The limiting bracket 224 simplifies the installation process of the first magnet 221, the second magnet 222, and the magnetic conductor 223, while also ensuring the connection stability between the first magnet 221, the second magnet 222, and the magnetic conductor 223.
[0041] In this embodiment, the load-bearing slider 20 also includes an overload load-bearing wheel 24, which protrudes from the other side of the fan body connecting plate 23. This overload load-bearing wheel 24 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. Normally, the magnetism of the magnet assembly 22 matches the mass of the fan body 3, and the overload load-bearing wheel 24 is not used. It is only necessary to use the overload load-bearing wheel 24 under special extreme conditions.
[0042] In another embodiment, the load-bearing slider 20 further includes an overload friction plate connected to the other side of the fan body connecting plate 23, which is used to contact the track structure 10 under extreme conditions to avoid contact between the fan body connecting plate 23 and the track structure 10.
[0043] 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.
