[0035] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0036] See also Figure 1-10 The present embodiment discloses a door and window, including a frame 2, a fan body 3 and a magnetic load-bearing device 1. The magnetic load-bearing device 1 is arranged between the frame 2 and the fan body 3, and is used to realize a magnetic suspension connection between the frame 2 and the fan body 3, which can ensure that the load-bearing slider 20 slides without friction, thereby reducing noise and facilitating pushing and pulling.

[0037] The track structure 10 is connected to the frame 2, and the magnetic load-bearing device 1 includes a load-bearing slider 20; the load-bearing slider 20 is connected to the fan body 3, and the load-bearing slider 20 is provided with a magnet assembly 22 and a guide member, the magnet assembly 22 and the track structure 10 attract each other, and the guide member is abutted against the track structure 10 to prevent the magnet assembly 22 from contacting the track structure 10 so that magnetic suspension is formed between the magnet assembly 22 and the track structure 10; wherein, the magnet assembly 22 includes a first magnet 221, a second magnet 222 and a magnet conductor 223, and the magnet conductor 223 is arranged between the first magnet 221 and the second magnet 222. The magnet assembly 22 is composed of the first magnet 221, the second magnet 222 and the magnet conductor 223. The magnet conductor 223 is arranged between the first magnet 221 and the second magnet 222 to enhance the magnetism, which can not only adapt to the movable fan with a larger dead weight, but also save costs.

[0038] The track structure 10 includes a track rod 11 and a track support 12. The track rod 11 is made of magnetic material or magnetic conductive material. The track support 12 is connected to the frame 2, and the track rod 11 is carried on the track support 12. The shape of the track rod 11 is square or round, and the shape of the track support 12 can be adjusted according to the shape of the track rod 11. For easy installation, the track rod 11 and the track support 12 can also be designed as an integrated structure.

[0039] It should be noted that the magnetic load-bearing device 1 in this solution is divided into a single-track magnetic load-bearing device 1 and a double-track magnetic load-bearing device 1.

[0040] The track support member 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 groups of magnet assemblies 22 and two groups of guide members. The two groups of magnet assemblies 22 are respectively arranged on both sides of the track rod 11, and the two groups of guide members respectively support the two sides of the track rod 11.

[0041] The track support member 12 in the double-track magnetic load-bearing device 1 is a U-shaped support member, two track rods 11 are respectively arranged on both sides of the track support member 12, a magnet assembly 22 is inserted between the two track rods 11, and a guide member is arranged in the middle of the magnet assembly 22 to abut against the track rod 11; or, at least two guide members are respectively arranged at both ends of the magnet assembly 22 to abut against the track rod 11. This embodiment is described by taking the double-track magnetic load-bearing device 1 as an example.

[0042] First embodiment

[0043] See also Figure 1-7 The guide member is a guide wheel 21. The guide wheel 21 is in direct rolling contact with the track rod 11, so that the sliding friction of the fan body 3 is small and the push and pull are labor-saving. Of course, the guide wheel 21 can also be replaced by a guide friction member.

[0044] In this embodiment, 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. It can be understood that the combination of the first magnet 221 and the second magnet 222 can better enhance the magnetism. Specifically, the magnetic conductor 223 is arranged 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.

[0045] In this embodiment, the length of the magnetizer 223 is greater than or equal to the length of the first magnet 221 and the length of the second magnet 222 to ensure that the magnetizer 223 can fully enhance the magnetic field. In a specific implementation, the lengths of the magnetizer 223, the first magnet 221 and the second magnet 222 are the same.

[0046] The thickness of the magnetizer 223 is less than or equal to the thickness of the first magnet 221 and the thickness of the second magnet 222 . When the thickness of the first magnet 221 is the same as the thickness of the second magnet 222 and is equal to twice the thickness of the magnetizer 223 , the magnetization effect is best.

[0047] The height of the magnetizer 223 is greater than or equal to the height of the first magnet 221 and the height of the second magnet 222 , wherein the height of the magnetizer 223 is equal to the height of the first magnet 221 and the height of the second magnet 222 , which saves the most materials.

[0048] In the actual production process, the first magnet 221 and the second magnet 222 can be selected to have the same structure to facilitate processing, installation, etc.

[0049] In this embodiment, the magnet assembly 22 also includes a limit bracket 224, and the limit bracket 224 is respectively provided with a receiving groove for accommodating the first magnet 221, the second magnet 222 and the conductive magnet 223. Most of the magnet assemblies 22 in the prior art are directly bonded to the bottom of the fan body 3, which is easy to fall off. The limit bracket 224 is used to carry the first magnet 221, the second magnet 222 and the conductive magnet 223, which is convenient for installation and not easy to fall off. In order to ensure the magnetic field magnetism, the limit bracket 224 can preferably use non-magnetic conductive materials. It can be understood that a protective shell 225 is also provided outside the limit bracket 224 to prevent the magnet from being exposed and causing it to fall or be damaged, thereby improving the aesthetics.

[0050] Specifically, the limiting bracket 224 includes a magnetic receiving groove 2241, a first magnet receiving groove 2242 and a second magnet receiving groove (not shown in the figure), the magnetic receiving groove 2241 runs through both ends of the limiting bracket 224, and is convenient for the magnet 223 to be loaded from both ends, the notch of the first magnet receiving groove 2242 is opened on one side of the limiting bracket 224, and the notch of the second magnet receiving groove is opened on the other side of the limiting bracket 224, after the magnet 223 is loaded, the first magnet 221 and the second magnet 222 can be stably installed in the first magnet receiving groove 2242 and the second magnet receiving groove respectively due to the magnetic attraction with the magnet 223. The setting of the limiting bracket 224 can simplify the installation process of the first magnet 221, the second magnet 222 and the magnet 223, and also ensure the connection stability between the first magnet 221, the second magnet 222 and the magnet 223.

[0051] In this embodiment, 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 magnetic conductive material, and a magnetic flux is formed between the first magnet 221, the magnetic conductive material 223, the second magnet 222 and the fan body connecting plate 23.

[0052] It should be noted that when the magnetic load-bearing device 1 is applied to the ground rail, the distance between the lower surface of the fan body connecting plate 23 and the upper surface of the track structure 10 is a, and the vertical distance between the lower surface of the magnet assembly 22 and the track structure 10 is b, satisfying that a is less than b; when the fan body 3 is light, the weight of the fan body 3 is borne by the magnetic attraction force between the magnet assembly 22 and the track structure 10; when the fan body 3 is heavy, the weight of the fan body 3 is borne by the magnetic flux formed between the magnet, the track structure 10 and the fan body connecting plate 23.

[0053] In this embodiment, the load-bearing slider 20 further includes an overload load-bearing wheel 24, which protrudes from the other side of the sector body connecting plate 23 and is used to contact the track structure 10 in an extreme state to avoid contact between the sector body connecting plate 23 and the track structure 10. Under normal circumstances, the magnetism of the magnet assembly 22 matches the mass of the sector body 3, and the overload load-bearing wheel 24 will not be used. Only under special extreme conditions, the overload load-bearing wheel 24 is needed to avoid crushing the magnet assembly 22.

[0054] Second embodiment

[0055] Different from the first embodiment, the fan body connecting plate 23 is made of non-magnetic conductive material, the track support member 12 is made of magnetic conductive material, and a magnetic flux is formed between the first magnet 221, the magnetic conductive member 223, the second magnet 222 and the track support member 12. When the fan body 3 is light, the weight of the fan body 3 is borne by the magnetic attraction between the magnet assembly 22 and the track structure 10; when the fan body 3 is heavy, the weight of the fan body 3 is borne by the magnetic flux formed between the magnet, the track structure 10 and the track support member 12. Of course, the track support member 12 can also be made of non-magnetic conductive material.

[0056] In the second embodiment, the guide member is a guide friction plate 25, which is in direct hard friction contact with the guide rail, has a large friction force, but has a low manufacturing cost and is easy to install. According to different usage scenarios, the guide wheel 21 or the guide friction plate 25 can be selected.

[0057] The overloaded load-bearing wheel 24 is replaced by an overloaded friction plate 26 , which is connected to the other side of the fan body connecting plate 23 and 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 .

[0058] The overload friction plate 26 can be an integrally formed structure with the guide friction plate 25, and the overall structure is L-shaped, with the horizontal part at the bottom of the fan body connecting plate 23 and the vertical part at the side wall of the magnet assembly 22, which can simultaneously ensure that the track rod 11 will not contact the fan body connecting plate 23 and the magnet assembly 22.

[0059] Third embodiment

[0060] Similar to the first embodiment, the fan body connecting plate 23 in the third embodiment is made of magnetic conductive material. Different from the first embodiment, the overload bearing structure in the third embodiment is an overload friction plate 26 .

[0061] Fourth embodiment

[0062] Similar to the second embodiment, the fan body connecting plate 23 in the fourth embodiment is made of non-magnetic material, and the material of the track support member 12 is magnetic material. Different from the second embodiment, the overload bearing structure in the fourth embodiment is an overload bearing wheel 24.

[0063] The advantages of this solution include:

[0064] 1. This structure can have a shock-absorbing effect similar to a spring, reducing vibration;

[0065] 2. The pushing and pulling process is all done by magnetic attraction without any noise;

[0066] 3. The push and pull force is light and is almost unaffected by the weight of the door leaf;

[0067] 4. The magnet assembly 22 has low cost.

[0068] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
