Description

Technical Field

[0001] This invention relates to the field of sliding door and window technology, specifically to a magnetically levitated sliding door. Background Technology

[0002] Existing sliding doors and windows have tracks at the bottom. The sliding doors and windows contact the tracks through rollers. The weight of the sliding doors and windows is mainly concentrated on the rollers. The rollers bear a large load and are prone to deformation or damage. The rollers experience significant wear as they slide on the tracks, and the friction is relatively high. Sliding the doors and windows is difficult and noisy. In addition, the tracks of existing sliding doors and windows are generally installed on the mounting surface, making them difficult to clean. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a magnetic levitation sliding door, which solves the problems of existing sliding doors and windows having large load-bearing pulleys that are prone to deformation or damage, high sliding friction, requiring considerable effort to slide, and producing significant noise during operation.

[0004] This invention provides a magnetically levitated sliding door, comprising:

[0005] A magnetic track, which is fixedly installed on a track base;

[0006] The U-shaped track frame comprises a top wall and two side walls connected to the lower side of the top wall. The two side walls are sandwiched between two sides of the magnetic track. Permanent magnets are disposed on the inner sides of the two side walls near their lower portions. The magnetic track is magnetically attracted to the permanent magnets on both sides, maintaining a gap between the track and the magnets. The U-shaped track frame is provided with at least two pairs of positioning wheels, each pair of which is respectively mounted on one of the two side walls of the U-shaped track frame and positioned on both sides of the magnetic track.

[0007] Sliding doors and windows, which are fixed to the top wall of the U-shaped track frame.

[0008] Furthermore, the magnetic track is made of magnetic metal material or permanent magnet material.

[0009] Furthermore, the two inner sides of the U-shaped track frame are provided with a first mounting step extending along the length direction near their lower part, and the permanent magnet is mounted on the first mounting step.

[0010] Furthermore, the permanent magnets on each side of the U-shaped track frame are composed of multiple bar magnets spliced ​​together.

[0011] Furthermore, the two ends of the two side walls of the U-shaped track frame are provided with a second mounting step, and the positioning wheels are provided in two pairs, with each pair of positioning wheels being installed on the second mounting step at one end of the two side walls.

[0012] Furthermore, it also includes a base frame, the top of which has a strip-shaped opening along its length. The base frame is placed below the mounting surface. The track seat is fixed to the lower side inside the base frame. The U-shaped track is installed inside the base frame. The upper side of the U-shaped track frame is provided with an I-shaped bracket. The I-shaped bracket has a lower wing plate, an upper wing plate, and a web plate connecting the lower wing plate and the upper wing plate. The lower wing plate is fixedly connected to the top wall of the U-shaped track frame, and the upper wing plate is fixedly connected to the lower end of the sliding door / window.

[0013] A decorative panel is provided on the mounting surface. The decorative panel has a vertically penetrating guide groove located directly above the strip opening. The web plate passes through the strip opening at the top of the bottom frame and the guide groove on the decorative panel.

[0014] Furthermore, L-shaped trim strips are provided on both sides of the web of the I-shaped bracket. One side of the L-shaped trim strip is located between the bottom frame and the decorative panel, and the other side is attached to the side end of the decorative panel near the guide groove.

[0015] Furthermore, each of the L-shaped closing strips is provided with a strip-shaped groove on its inner side, and a brush is installed in the strip-shaped groove, with the brushes on both sides extending towards the middle.

[0016] Furthermore, the lower end of the sliding door / window has a frame, the bottom of which is provided with a mounting groove, and the upper wing plate of the I-shaped bracket is embedded and fixed in the mounting groove.

[0017] The beneficial effects of this invention are as follows: By setting permanent magnets and positioning wheels on both sides of the magnetic track, the positioning wheels are positioned between the magnetic track and the U-shaped track frame to ensure that the magnetic track is located in the middle of the permanent magnets on both sides and to ensure that the magnetic track and the permanent magnets on both sides always maintain a gap, preventing one side of the permanent magnet from adsorbing onto the magnetic track. Under the magnetic attraction of the magnetic track and the permanent magnets on both sides, the U-shaped track frame is suspended on the magnetic track, and the weight of the sliding door and window is borne on the U-shaped track frame. Compared with the pulley load-bearing structure of traditional sliding doors and windows, the load-bearing structure of this application has more dispersed force, is less prone to damage, has stronger load-bearing capacity, and causes less wear on the track when the sliding door and window slides. The sliding friction is very small, making pushing and pulling easier and generating very little noise. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0025] like Figures 1-3 As shown, this embodiment of the invention provides a magnetic levitation sliding door, including a magnetic track 100, a U-shaped track frame 200, and a sliding door / window 300.

[0026] The magnetic track 100 is fixedly installed on a track base 110. The magnetic track 100 can be made of magnetic metal material or permanent magnet material.

[0027] The U-shaped track frame 200 can be made of steel and consists of a top wall 210 and two side walls 220 connected to the lower side of the top wall 210. The two side walls 220 are sandwiched between the two sides of the magnetic track 100. Permanent magnets 230 are provided on the inner side of the two side walls 220 near their lower part. The magnetic track 100 is magnetically attracted to the permanent magnets 230 on both sides and maintains a gap with the permanent magnets 230 on both sides. The U-shaped track frame 200 is provided with at least two pairs of positioning wheels 240. Each pair of positioning wheels 240 is installed on the two side walls 220 of the U-shaped track frame 200 and is limited to the two sides of the magnetic track 100.

[0028] To facilitate the installation of permanent magnets 230 on the side walls 220 of the U-shaped track frame 200, a first mounting step 221 extending along the length direction is provided on the relatively inner side of the two side walls 220 of the U-shaped track frame 200 near their lower part. The permanent magnets 230 are mounted on the first mounting steps 221. The permanent magnets 230 can be aligned with the inner surface of the side wall 220 or extend beyond the inner surface of the side wall 220. In this embodiment, the permanent magnets 230 on each side of the U-shaped track frame 200 are composed of multiple bar magnets spliced ​​together.

[0029] To facilitate the installation of positioning wheels 240 on the side walls 220 on both sides of the U-shaped track frame 200, a second mounting step 222 is provided at both ends of the two side walls 220 of the U-shaped track frame 200. In this embodiment, two pairs of positioning wheels 240 are specifically provided, and each pair of positioning wheels 240 is installed on the second mounting step 222 at one end of the two side walls 220.

[0030] The sliding door and window 300 is fixed to the top wall 210 of the U-shaped track frame 200. It should be noted that the sliding door and window 300 can be directly fixed to the top wall 210 of the U-shaped track frame 200, or it can be indirectly fixed to the top wall 210 of the U-shaped track frame 200 through a bracket.

[0031] This application provides permanent magnets 230 and positioning wheels 240 on both sides of the magnetic track 100. The positioning wheels 240 position the magnetic track 100 and the U-shaped track frame 200 to ensure that the magnetic track 100 is located in the middle of the permanent magnets 230 on both sides and to ensure that the magnetic track 100 and the permanent magnets 230 on both sides always maintain a gap, preventing one side of the permanent magnet 230 from adsorbing onto the magnetic track 100. Under the magnetic attraction between the magnetic track 100 and the permanent magnets 230 on both sides, the U-shaped track frame 200 is suspended on the magnetic track 100. The weight of the sliding door and window 300 is supported on the U-shaped track frame 200. Compared with the pulley load-bearing structure of the traditional sliding door and window 300, the load-bearing structure of this application has a more distributed force, is less prone to damage, has a stronger load-bearing capacity, and causes less wear on the track when the sliding door and window 300 slides. The sliding friction is very small, making it easier to push and pull, and the noise generated during pushing and pulling is very small.

[0032] The principle by which the U-shaped track frame 200 remains suspended under the action of magnetic attraction is as follows: When the U-shaped track frame 200 is under load, it will move downward to a certain extent. At this time, under the action of magnetic attraction, the magnetic track 100 will exert an upward attraction on the permanent magnets 230 on both sides. When the vertical component of this attraction is equal to the overall weight, the U-shaped track frame 200 will remain suspended and balanced.

[0033] The magnetic levitation sliding door of this application is different from the electrically driven magnetic levitation sliding door on the market. Instead, it adopts permanent magnet 230 magnetic levitation load-bearing sliding door, which has a strong load-bearing capacity. The load-bearing capacity can be increased by increasing the number, size or magnetic force of permanent magnet 230, etc., and the load-bearing capacity can reach one ton or several tons.

[0034] In a preferred embodiment, the magnetic levitation sliding door further includes a bottom frame 400, which may be made of aluminum alloy. The top of the bottom frame 400 has a strip-shaped opening 410 along its length. The bottom frame 400 is placed below the mounting surface. The track seat 110 is fixed to the lower side inside the bottom frame 400. The U-shaped track frame 200 is located inside the bottom frame 400. The upper side of the U-shaped track frame 200 is provided with an I-shaped bracket 500, which may be made of aluminum alloy. It has a lower wing plate 510, an upper wing plate 520, and a web plate 530 connecting the lower wing plate 510 and the upper wing plate 520. The lower wing plate 510 is fixedly connected to the top wall 210 of the U-shaped track frame 200, and the upper wing plate 520 is fixedly connected to the lower end of the sliding door 300. A decorative panel 600 is provided on the mounting surface. The decorative panel 600 is located directly above the strip opening 410 and has a vertically penetrating guide groove 610. The web plate 530 passes through the strip opening 410 on the upper part of the bottom frame 400 and the guide groove 610 on the decorative panel 600.

[0035] This application conceals the track beneath the mounting surface. The sliding door / window 300 is supported on the U-shaped track frame 200 by an I-beam bracket 500. Only a guide groove 610 is left on the decorative panel 600 for the web plate 530 of the I-beam bracket 500 to pass through. The width of the guide groove 610 is slightly larger than the thickness of the web plate 530 of the I-beam bracket 500. Only a very small gap will exist on the decorative panel 600, which not only facilitates cleaning but also makes the appearance more aesthetically pleasing.

[0036] Preferably, L-shaped trim strips 700 are provided on both sides of the web plate 530 of the I-shaped bracket 500. The L-shaped trim strips 700 can be made of aluminum alloy. One side of the L-shaped trim strip 700 is located between the bottom frame 400 and the decorative panel 600, and the other side is attached to the side end of the decorative panel 600 near the guide groove 610. The L-shaped trim strip 700 can protect the side end of the decorative panel 600.

[0037] More preferably, each L-shaped trim strip 700 is provided with a strip groove 710 on its inner side. A brush 800 is installed in the strip groove 710. The brushes 800 on both sides extend towards the middle. This allows the brushes 800 to seal the guide groove 610, preventing dust or debris from entering the bottom frame 400, while not affecting the sliding of the sliding door and window 300.

[0038] In addition, the lower end of the sliding door and window 300 has a frame 310, which can be made of aluminum alloy. The bottom of the frame 310 is provided with a mounting groove 311. The upper wing plate 520 of the I-shaped bracket 500 is embedded and fixed in the mounting groove 311, which facilitates the installation and positioning between the sliding door and window 300 and the I-shaped bracket 500.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
