Description

Technical Field

[0001] This utility model relates to the field of building doors and windows, and more specifically, to a magnetically levitated heavy-duty sliding door. Background Technology

[0002] In the home decoration door and window market, end users are increasingly demanding higher performance from balcony and outdoor doors. The mainstream form of balcony doors is sliding doors, with heavy-duty sliding doors and panoramic sliding doors being particularly popular. The development trend of heavy-duty sliding doors is increasingly towards high load-bearing capacity, large span (5-7 meters in width), and wide field of vision, which means that the door panels are quite heavy. This also leads to some unavoidable drawbacks.

[0003] like Figure 1 and Figure 2 As shown, both traditional heavy-duty sliding door designs and panoramic sliding door designs consist of an upper slide 1, a lower slide 2, a side seal 4, and a door leaf 3. However, when manufacturing this type of large-opening, large-glass, heavy-duty, and large-span sliding door, both share the same fundamental problems due to factors such as the building's ground or floor surface and the door's installation location. It is well known that when the width of a sliding door exceeds 5 meters, the lower slide 2 is installed flush against the ground or floor surface. However, the ground or floor surface is often uneven. Under the weight of the door leaf 3, the lower slide 2 also bends, making it particularly difficult for users to push and pull the door, and sometimes it may even become impossible to push. Utility Model Content

[0004] Based on this, in order to solve the problem of users finding heavy-duty sliding doors difficult to open and close, this utility model provides a magnetic levitation heavy-duty sliding door, the specific technical solution of which is as follows:

[0005] A magnetically levitated heavy-duty sliding door includes an upper slide, a lower slide, a door leaf, and a pair of side seals. The upper slide and the lower slide are vertically opposite each other, and the two side seals are respectively installed on both sides between the upper slide and the lower slide. The door leaf is slidably installed on the upper slide and the lower slide at both ends in the vertical direction. The lower slide includes a base, a suspension track, several electromagnets, and several strong magnets. The base has an installation groove on the side near the door leaf. The several electromagnets are spaced apart along the length of the lower slide and are fixedly installed in the bottom of the installation groove. The suspension track is installed in the installation groove and is located on the side of the electromagnets near the door leaf. The several strong magnets are all installed on the suspension track, and the several strong magnets are arranged in a one-to-one correspondence with the several electromagnets. The door leaf is slidably installed on the suspension track.

[0006] By adopting the above technical solution, when the door needs to be pushed or pulled, each electromagnet is activated, causing the electromagnets and strong magnets to repel each other, thus suspending the entire suspension track at a certain height. This prevents the suspension track for sliding the door from contacting the floor or ground, but instead relies on magnetic levitation to lift the suspension track and the door. This ensures that the suspension track, which is in direct contact with the door, will not be damaged after contacting the floor or ground, and the base, which is in contact with the floor or ground, will not be damaged by pressure. As a result, users can push and pull heavy-duty sliding doors more smoothly and effortlessly, improving ease of use.

[0007] Furthermore, the magnetic field strength of the plurality of electromagnets gradually decreases with the sliding direction of the door leaf, and a control component for controlling the magnetic field strength of the plurality of electromagnets is also included.

[0008] Furthermore, one side of the door leaf is the closed side and the other side is the open side. The control component includes a contact sensor and a first magnet controller for controlling the magnetic field strength of each electromagnet. The contact sensor and the first magnet controller are both installed on the side seal facing the closed side. The contact sensor and the first magnet controller are signal connected, and the first magnet controller is electrically connected to each electromagnet.

[0009] Furthermore, the control component also includes a distance sensor and a second magnet controller for controlling the magnetic field strength of each of the electromagnets. The distance sensor and the second magnet controller are both installed on the side seal facing the opening side. The detection end of the distance sensor faces the door leaf. The distance sensor and the second magnet controller are signal connected, and the second magnet controller is electrically connected to each of the electromagnets.

[0010] Furthermore, a locking device for locking the door leaf to the side seal and a locking controller for controlling the opening and closing of the locking device are installed on the closed side, and the locking controller is signal-connected to the locking device.

[0011] Furthermore, a number of pulleys are installed at intervals along the sliding direction at the bottom of the door leaf, and the pulleys are rolled on the suspended track.

[0012] Furthermore, a groove is provided on the side of the suspended track away from the mounting groove, and the pulley is rotatably installed in the groove.

[0013] Furthermore, each door leaf includes a door frame and glass, with the glass snapped and fixedly installed in the door frame, and the pulley installed at the bottom of the door frame.

[0014] Furthermore, a baffle is provided on the side of the sliding door facing the interior, and the baffle is higher than the bottom of the door leaf.

[0015] Furthermore, the door leaf is provided in pairs, and the two door leaves are spaced apart and staggered in the thickness direction of the edge seal. Attached Figure Description

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, a magnetic levitation heavy-duty sliding door according to one embodiment of the present invention includes an upper slide 1, a lower slide 2, a pair of door leaves 3 and a pair of side seals 4. The upper slide 1 and the lower slide 2 are arranged opposite each other in the vertical direction. The two side seals 4 are respectively installed on both sides between the upper slide 1 and the lower slide 2. The upper slide 1, the lower slide 2 and the two side seals 4 form a door frame. The two door leaves 3 are spaced apart and staggered in the thickness direction of the side seals 4. The two door leaves 3 are slidably installed on the upper slide 1 and the lower slide 2 at both ends in the vertical direction.

[0032] The sliding mechanism 2 includes a base 21, a suspension track 22, several electromagnets 23, and several strong magnets 24. The base 21 has mounting slots 211 at the positions corresponding to the two door panels 3. Several electromagnets 23 are installed in each mounting slot 211, spaced apart along the length of the sliding mechanism 2, and fixedly installed at the bottom of the mounting slot 211. The suspension track 22 is installed within the mounting slot 211, with gaps between the suspension track 22 and the wall of the mounting slot 211. The suspension track 22 is located on the side of the electromagnets 23 closest to the door panels 3. The strong magnets 24 are all strong permanent magnets, and several strong magnets 24 are installed on the suspension track 22, with each strong magnet 24 corresponding to one of the electromagnets 23. The door panels 3 are slidably installed on the suspension track 22.

[0033] Therefore, when the door leaf 3 needs to be pushed or pulled, each electromagnet 23 is activated, causing the electromagnet 23 and the strong magnet 24 to repel each other due to their similar poles. This causes the entire suspension track 22 to be suspended at a certain height, so that the suspension track 22 for sliding the door leaf 3 does not contact the floor or ground. Instead, the suspension track 22 and the door leaf 3 are lifted by magnetic levitation, so that the suspension track 22, which is in direct contact with the door leaf 3, will not be crushed after contacting the ground or floor, and the base 21, which is in contact with the ground or floor, will not be crushed by pressure.

[0034] like Figure 5 and Figure 6 As shown, the magnetic field strength of several electromagnets 23 in the same row gradually decreases with the sliding direction of the door leaf 3. The magnetic levitation heavy-duty sliding door also includes a control component for controlling the magnetic field strength of several electromagnets 23 in the same row; one side of the door leaf 3 is the closing side 31, and the other side is the opening side 32. The control component includes a contact sensor 5 and a first magnet controller 6 for controlling the magnetic field strength of each electromagnet 23. The contact sensor 5 is model JC-TM803, and the first magnet controller 6 is model QUK-01 / 10A. The contact sensor 5 and the first magnet controller 6 are both fixedly installed on the side seal 4 opposite the closing side 31. The contact sensor 5 and the first magnet controller 6 are signal connected, and the first magnet controller 6 is electrically connected to each electromagnet 23. The electromagnets 23, the contact sensor 5, and the first magnet controller 6 are all powered by the indoor power supply. Figure 6 , Figure 7 and Figure 8 When the user pushes the door 3 away from the contact sensor 5, the contact sensor 5 sends a signal to the first magnet controller 6. The first magnet controller 6 controls the magnetic field strength of each electromagnet 23 to gradually decrease in the opening and sliding direction of the door 3, so that the suspension track 22 tilts to form an angle α. Thus, under the influence of gravity G, the door 3 is naturally subjected to a horizontal auxiliary thrust F. This force can help the user to easily push the door 3. The greater the gravity of the door 3, the greater its horizontal auxiliary thrust F, further improving the smoothness of pushing the door 3.

[0035] like Figure 5 and Figure 6 As shown, the control assembly also includes a distance sensor 7 and a second magnet controller 8 for controlling the magnetic field strength of each electromagnet 23. The distance sensor 7 is model DYP-A19-V1.0, and the second magnet controller 8 is model QUK-01 / 10A. Both the distance sensor 7 and the second magnet controller 8 are installed on the side seal 4 directly opposite the opening side 32. The detection end of the distance sensor 7 faces the door leaf 3. The distance sensor 7 and the second magnet controller 8 are signal-connected, and the second magnet controller 8 is electrically connected to each electromagnet 23. Both the distance sensor 7 and the second magnet controller 8 are powered by an indoor power source. (Refer to...) Figure 6, Figure 7 and Figure 8 When the user pulls the door leaf 3 away from the distance sensor 7, the distance sensor 7 detects that the distance is getting farther and farther away. Then the distance sensor 7 sends a signal to the second magnet controller 8. At this time, the first magnet controller 6 is in the off state, and the second magnet controller 8 controls the magnetic field strength of each electromagnet 23 to gradually decrease in the closing sliding direction of the door leaf 3, so that the suspension track 22 tilts to form an angle α. Thus, under the influence of gravity G, the door leaf 3 is naturally subjected to a horizontal auxiliary thrust F. This force can help the user to easily pull the door leaf 3. The greater the gravity of the door leaf 3, the greater its horizontal auxiliary thrust F, further improving the smoothness of pulling the door leaf 3.

[0036] like Figure 5 As shown, a locking device 9 for locking the door leaf 3 to the side seal 4 and a locking controller 10 for controlling the opening and closing of the locking device 9 are installed on the closed side 31. The locking device 9 is model 62.3008L2402 and the locking controller 10 is model ALT03H. The locking controller 10 is signal-connected to the locking device 9 and electrically connected to indoor switches and other components. Thus, when the locking controller 10 receives an opening signal, it can control the door opener to open.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the bottom of the door leaf 3 is equipped with several pulleys 33 at intervals along the sliding direction, while the top of the door leaf 3 is provided with anti-sway wheels (not shown in the figure); the side of the suspended track 22 away from the mounting groove 211 is provided with a sliding groove 221, and the pulleys 33 are rolled in the sliding groove 221, that is, the pulleys 33 are rolled on the suspended track 22; each door leaf 3 includes a leaf frame 34 and glass 35, the glass 35 is snapped and fixedly installed in the leaf frame 34, and the pulleys 33 are installed at the bottom of the leaf frame 34; the side of the base 21 facing the interior is provided with a baffle 212, which is higher than the bottom of the door leaf 3, so as to make the appearance more beautiful and also play a certain role in waterproofing.

[0038] The implementation principle of a magnetic levitation heavy-duty sliding door according to an embodiment of this application is as follows: When the door leaf 3 needs to be pushed open, the locking controller 10 controls the locking device 9 to open, and then pushes the door leaf 3 away from the contact sensor 5. The contact sensor 5 sends a signal to the first magnet controller 6, and the first magnet controller 6 controls the magnetic field strength of each electromagnet 23 to gradually decrease in the opening sliding direction of the door leaf 3, so that the door leaf 3 can be opened smoothly; when the door leaf 3 needs to be pulled closed, the door leaf 3 is pulled away from the distance sensor 7. The distance sensor 7 detects that the distance is getting farther and farther, and then the distance sensor 7 sends a signal to the... The second magnet controller 8 controls the magnetic field strength of each electromagnet 23 to gradually decrease in the closing sliding direction of the door leaf 3, thereby activating each electromagnet 23 so that the door leaf 3 can close smoothly. The above operation ensures that the floating track 22 for sliding the door leaf 3 does not contact the floor or ground, but relies on the magnetic levitation to lift the floating track 22 and the door leaf 3, so that the floating track 22, which is in direct contact with the door leaf 3, will not be crushed after contacting the ground or floor, and the base 21, which is in contact with the ground or floor, will not be crushed by pressure.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
