[0031] In addition, the technical features involved in different embodiments of the application described below can be combined with each other as long as there is no conflict.
[0032] Referring to Figure 1 The embodiment discloses a door and window, comprising a frame body 2, a fan body 3 and a magnetic attraction load bearing device 1, the magnetic attraction load bearing device 1 is arranged between the frame body 2 and the fan body 3, and is used for realizing the magnetic levitation connection of the frame body 2 and the fan body 3, can guarantee the frictionless sliding of the load bearing slider 20, reduces the noise, and facilitates the push and pull.
[0033] Referring to Figures 2-6 The track structure 10 is connected to the frame body 2; the magnetic attraction load bearing device 1 comprises a load bearing slider 20 and a first magnetic conductor 30, the load bearing slider 20 is connected to the fan body 3, the load bearing slider 20 is provided with a magnet assembly 22 and a guide piece, the magnet assembly 22 and the track structure 10 are attracted to each other, the guide piece abuts against the track structure 10, so that the magnet assembly 22 and the track structure 10 are not in contact, and the magnetic levitation is formed between the magnet assembly 22 and the track structure 10; the first magnetic conductor 30 is close to the magnet assembly 22 and the track structure 10, so that the magnetic flux is formed among the magnet assembly 22, the first magnetic conductor 30 and the track structure 10.
[0034] By arranging the first magnetic conductor 30 close to the magnet assembly 22 and the track structure 10, the magnetic flux is formed among the three, and the original magnetism between the magnet assembly 22 and the track structure 10 is enhanced, so that the magnetic levitation sliding of the fan body 3 can be guaranteed on the premise of saving the cost of the magnet material.
[0035] The track structure 10 comprises a track rod 11 and a track support 12, the track rod 11 is made of a magnetic material or a magnetic conductive material, the track support 12 is connected to the frame body 2, and the track rod 11 is borne on the track support 12. The shape of the track rod 11 is square or circular, and the shape of the track support 12 can be adjusted adaptively according to the shape of the track rod 11. In order to facilitate installation, the track rod 11 and the track support 12 can also be designed as an integral structure.
[0036] It should be noted that the magnetic attraction load bearing device 1 in the scheme is divided into a single-track magnetic attraction load bearing device 1 and a double-track magnetic attraction load bearing device 1.
[0037] The track support 12 in the single-track magnetic attraction load bearing device 1 is T-shaped, and a track rod 11 is arranged in the middle. The load bearing slider 20 comprises two groups of magnet assemblies 22 and two groups of guide members. The two groups of magnet assemblies 22 are arranged on the two sides of the track rod 11 respectively, and the two groups of guide members abut against the two sides of the track rod 11 respectively.
[0038] The track support 12 in the double-track magnetic attraction load bearing device 1 is a U-shaped support. Two track rods 11 are arranged on the two sides of the track support 12 respectively. The magnet assembly 22 is inserted between the two track rods 11. One guide member is arranged in the middle of the magnet assembly 22 to abut against the track rod 11. Alternatively, at least two guide members are arranged at the two ends of the magnet assembly 22 to abut against the track rod 11. This embodiment is described by taking the double-track magnetic attraction load bearing device 1 as an example.
[0039] In this embodiment, the first magnetic conductor 30 is slidingly connected to the load bearing slider 20, and the first magnetic conductor 30 is arranged opposite to the track structure 10 in the vertical direction.
[0040] Specifically, the load bearing slider 20 further comprises a fan connecting plate 23 and a guide column 25. One side of the fan connecting plate 23 is connected to the fan 3, and the other side of the fan connecting plate 23 is connected to one end of the guide column 25. The other end of the guide column 25 is connected to the magnet assembly 22. The first magnetic conductor 30 is sleeved on the guide column 25 and is arranged between the other side of the fan connecting plate 23 and the track structure 10.
[0041] It can be understood that the first magnetic conductor 30 slides between the other side of the fan connecting plate 23 and one side of the magnet assembly 22, and the height of the guide column 25 is greater than the thickness of the first magnetic conductor 30. The magnet assembly 22 is magnetically attracted to the track rod 11 from the side, and the first magnetic conductor 30 is arranged opposite to the track rod 11 in the vertical direction. When the distance between the magnet assembly 22, the first magnetic conductor 30 and the track rod 11 is very close, a stable magnetic flux is formed among them, so that the magnetism can be enhanced. The arrangement of the first magnetic conductor 30 can meet the corresponding magnetism requirement under the premise of reducing the use of magnet material, thereby saving cost. It should be noted that in the vertical direction, the maximum distance between the first magnetic conductor 30 and the fan 3 connecting member should be less than the maximum distance between the magnet assembly 22 and the track support 12, so as to ensure that even if the first magnetic conductor 30 contacts the track rod 11, the magnet assembly 22 will not contact the track support 12.
[0042] The load-bearing sliding block 20 is installed in the door leaf profile, the track bar 11 and the track support 12 are placed in the door and window frame, when the door leaf is under the action of gravity, the magnetic attraction force formed by the two side magnet rows (magnet assembly 22) and the first magnetic conductor 30 supports the weight of the door leaf, and the guide wheel 21 makes the load-bearing sliding block 20 always in the middle of the two track bars 11, ensuring the smoothness and stability of the door leaf sliding process. When the door leaf weight exceeds the support force of the magnet row, the overload load-bearing wheel plays a supporting role. The gap distance between the track bar 11 and the overload load-bearing wheel is within the limit support range of the magnetic attraction force of the magnet row, which not only ensures the effective load-bearing of the magnetic attraction force, but also ensures the smoothness when the door leaf weight does not exceed the limit load-bearing.
[0043] When the door leaf weight is very light, the magnetic attraction force generated by the magnet row and the track serves as the main load-bearing force. When the door leaf weight is heavier but does not exceed the magnetic attraction force generated by the magnetic flux, the magnetic flux and the magnetic attraction force serve as the main load-bearing force.
[0044] In the embodiment, the magnet assembly 22 includes a limiting support 224, a first magnet 221, a second magnet 222, a second magnetic conductor 223, and a protective shell 225. The first magnet 221, the second magnet 222, and the second magnetic conductor 223 are all contained in the limiting support 224, and the second magnetic conductor 223 is arranged between the first magnet 221 and the second magnet 222. The protective shell 225 covers the limiting support 224 to prevent the first magnet 221, the second magnet 222, and the second magnetic conductor 223 from falling out.
[0045] Referring to Figure 7 , the limiting support 224 includes a magnetic conductor containing groove, a first magnet 221 containing groove, and a second magnet 222 containing groove (not shown in the figure). The magnetic conductor containing groove penetrates through both ends of the limiting support 224, facilitating the second magnetic conductor 223 to be loaded from both ends. The slot opening of the first magnet 221 containing groove is arranged on one side of the limiting support 224, and the slot opening of the second magnet 222 containing groove is arranged on the other side of the limiting support 224. After the second magnetic conductor 223 is loaded, the first magnet 221 and the second magnet 222 are respectively stably installed in the first magnet 221 containing groove and the second magnet 222 containing groove due to the magnetic attraction force with the second magnetic conductor 223. The arrangement of the limiting support 224 can simplify the installation process of the first magnet 221, the second magnet 222, and the second magnetic conductor 223, and also ensures the stability of the connection between the first magnet 221, the second magnet 222, and the second magnetic conductor 223.
[0046] In the 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. The second 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.
[0047] In the embodiment, the length of the magnetic conductor is greater than or equal to the length of the first magnet 221 and the length of the second magnet 222, so as to ensure that the magnetic conductor can comprehensively enhance the magnetic field magnetism. In a specific implementation, the lengths of the magnetic conductor, the first magnet 221 and the second magnet 222 are the same.
[0048] The thickness of the magnetic conductor 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 and the thickness of the second magnet 222 are the same and equal to twice the thickness of the magnetic conductor, the magnetic effect is the best.
[0049] The height of the magnetic conductor is greater than or equal to the height of the first magnet 221 and the height of the second magnet 222. The height of the magnetic conductor is equal to the height of the first magnet 221 and the height of the second magnet 222, which is the most material-saving.
[0050] In actual production, the first magnet 221 and the second magnet 222 can be selected to have the same structure, which is convenient for processing, installation and the like.
[0051] In the embodiment, the guide 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 pushing and pulling is labor-saving. Of course, the guide wheel 21 can also be replaced by a guide friction member.
[0052] In the embodiment, the load-bearing sliding block 20 further comprises an overload load-bearing wheel 24 protruding from the first magnetic conductor 30, which is used to contact the track structure 10 in an extreme state to avoid the fan body connecting plate 23 from contacting the track structure 10. Normally, the magnetism of the magnet assembly 22 and the mass of the fan body 3 are matched, the first magnetic conductor 30 and the overload load-bearing wheel 24 do not contact the track rod 11, and the overload load-bearing wheel 24 is not used. Only in a special extreme state, the overload load-bearing wheel 24 needs to be used to avoid crushing the first magnetic conductor 30 or the magnet assembly 22.
[0053] In another embodiment, the load-bearing wheel can be replaced by an overload friction plate, which protrudes from the first magnetic conductor 30 and is used to contact the track structure 10 in an extreme state to avoid the fan body connecting plate 23 from contacting the track structure 10.
[0054] The advantages of the scheme include:
[0055] 1. The structure can have a spring-like damping effect, reducing vibration;
[0056] 2. The push-pull process is affected by magnetic attraction without noise;
[0057] 3. The push-pull force is light and almost unaffected by the weight of the door leaf;
[0058] 4. The magnet assembly 22 is low in cost.
[0059] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
