Description

Technical Field

[0001] This utility model relates to the field of door and window devices, and in particular to a magnetic door and window device for aluminum-wood composite doors and windows. Background Technology

[0002] With societal development, there are now many types of doors and windows available. Aluminum-wood composite doors and windows are a type of door and window product that combines aluminum alloy and wood. They retain the style of solid wood doors and windows while being covered with an aluminum alloy exterior, offering excellent physical properties, outstanding energy efficiency, and strong weather resistance. The magnetic application in aluminum-wood composite doors and windows is mainly reflected in the design of magnetic devices within the door and window frames. These devices use magnetic force to automatically close or keep the doors and windows closed, combining practicality with a high-tech feel.

[0003] In applications such as doors and windows that open and close frequently, the design that relies on direct magnetic attraction for closure, while simple in structure, is prone to instantaneous impact force with each closure. This direct rigid collision may damage the magnet under long-term, repeated stress concentration, posing a safety hazard of brittle fracture of the magnet, reducing the service life of the magnetic attraction structure, and affecting the user experience. Utility Model Content

[0004] This utility model provides a magnetic attraction device for aluminum-wood composite doors and windows, which can solve the problem that direct rigid collision of magnets with existing magnetic attraction devices for aluminum-wood composite doors and windows may damage the magnets and reduce the service life of the magnetic attraction structure.

[0005] A magnetic suction device for aluminum-wood composite doors and windows includes a window frame and a window sash. A magnetic suction component is provided on the opposite side of the window frame and the window sash. The magnetic suction component includes a mounting base, a magnet disposed inside the mounting base, a yoke layer fixed inside the mounting base, and an elastic buffer pad fixed on the mounting base. The mounting base is embedded inside the corresponding window frame or window sash. The yoke layer is located between the back of the magnet and the mounting base, the elastic buffer pad is located at the working surface of the magnet, and the surface of the elastic buffer pad is slightly higher than the surface of the magnet. The magnets on the window frame and the magnets on the window sash generate magnetic attraction.

[0006] Preferably, the magnetic attraction component further includes a protective film that can be peeled off and attached to the working surface of the magnet.

[0007] Preferably, the magnetic attraction assembly further includes a first positioning component for detachably fixing the magnet to the mounting base.

[0008] Preferably, the first positioning component includes a plurality of first screws and clamps threaded onto the mounting base, the clamps being fitted against one side of the magnet, and one end of the first screws abutting against the clamps.

[0009] Preferably, the magnetic suction assembly further includes a limiting component for detachably fixing the mounting base to the corresponding window frame or window sash.

[0010] Preferably, the limiting component includes a slot formed on the side of the mounting base, a block inserted into the slot, and a second screw disposed on the side of the mounting base and the slot and opposite to the slot. The block is fixed to the corresponding window frame or window sash, and the second screw is threadedly connected to the corresponding window frame or window sash.

[0011] Preferably, the magnetic assembly further includes a heat insulation layer located on the back of the mounting base.

[0012] Preferably, the protective film includes a thin film layer and a pressure-sensitive adhesive layer disposed on the thin film layer.

[0013] Preferably, the magnet is a neodymium iron boron permanent magnet.

[0014] Preferably, both the first screw and the second screw have a hexagonal groove at one end. The end of the first screw with the hexagonal groove is flush with or slightly lower than the outer surface of the mounting base, and the end of the second screw with the hexagonal groove is flush with or slightly lower than the outer surface of the corresponding window frame or window sash.

[0015] This utility model provides a magnetic door and window device for aluminum-wood composite doors and windows, which has the following beneficial effects: 1. A magnetic attraction component is embedded in the mounting groove on the closed side of the window frame and sash. By setting a magnetic yoke iron layer on the back of the magnet, the magnetic lines of force are effectively guided and concentrated, which helps to enhance the attraction effect and reliability. At the same time, an elastic buffer pad is added to the working surface of the magnet, which is slightly higher than the surface of the magnet. When closing, it can first contact the sash, and gradually buffer and reduce the magnetic gap through elastic deformation, so that the magnet can smoothly reach the optimal attraction distance and ensure the stable sealing of the sash. In addition, the addition of an elastic buffer pad avoids hard high-speed collisions when the magnet is attracted, reducing impact damage to the magnet, thereby improving the durability and overall reliability of the magnetic attraction structure.

[0016] 2. The magnet is placed inside the mounting base, and the magnet can be firmly clamped onto the mounting base by the cooperation of the first screw and the clamping plate. The abutment clamping method facilitates quick assembly and disassembly; moreover, the mounting base can be easily detached and fixed to the window frame or window sash by the cooperation of the slot and the second screw, which is used to tighten it. The assembly and disassembly are simple, which facilitates the subsequent maintenance or replacement of the magnet inside the mounting base.

[0017] 3. A heat insulation layer is installed on the side of the magnet that is closest to the external environment. This can effectively block the thermal shock of outdoor temperature changes to the magnet and help protect the magnet's performance. At the same time, a protective film is attached to the working surface of the magnet to keep it protected during the transportation, installation and decoration of doors and windows, preventing scratches, cement, paint and other contaminants from affecting the magnetic attraction effect.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 5As shown in the figure, the present invention provides a magnetic attraction device for aluminum-wood composite doors and windows, including a window frame 1 and a window sash 2. Magnetic attraction components 3 are provided on opposite sides of the window frame 1 and the window sash 2. The magnetic attraction components 3 include a mounting base 31, a magnet 32 ​​disposed inside the mounting base 31, a yoke layer 33 fixed inside the mounting base 31, and an elastic buffer pad 36 fixed on the mounting base 31. The mounting base 31 is embedded inside the corresponding window frame 1 or window sash 2. The yoke layer 33 is located between the back of the magnet 32 ​​and the mounting base 31. The elastic buffer pad 36 is located at the working surface of the magnet 32, and the surface of the elastic buffer pad 36 is slightly higher than the surface of the magnet 32. The magnet 32 ​​on the window frame 1 and the magnet 32 ​​on the window sash 2 generate magnetic attraction.

[0022] On the side where the window frame 1 and window sash 2 close together, a mounting groove is pre-cut, and the magnetic component 3 is embedded in the mounting groove, thereby achieving a flat and integrated installation with the door and window profiles, resulting in a simple and beautiful appearance. The magnetic component 3 has a built-in magnet 32, and a yoke layer 33 made of magnetically conductive material (such as low-carbon steel) is set between the back of the magnet 32 ​​(i.e., the side facing away from the working surface) and the mounting base 31, so that the magnetic lines of force are efficiently guided and concentrated, enhancing the actual attraction effect and improving the reliability of use.

[0023] Furthermore, an elastic buffer pad 36 is provided on the working surface (adsorption and contact surface) of the magnet 32. The elastic buffer pad 36 can be made of a weather-resistant elastic material (such as rubber, silicone, or TPE), and its surface is slightly higher than the surface of the magnet 32 ​​after installation. When the window sash 2 is close, the elastic buffer pad 36 makes contact first, and there is still a small gap between the magnets 32. As the closing action continues, the elastic buffer pad 36 is compressed and undergoes elastic deformation to provide a buffering effect, during which the final gap between the magnets 32 is smoothly reduced. When the elastic buffer pad 36 is compressed to the end of its stroke, the magnets 32 are at the optimal working distance for basic contact, ensuring a stable adsorption force to seal the window sash 2. By setting the elastic buffer pad 36, the originally rigid, high-speed collision adsorption is avoided, reducing the damage to the magnets 32 caused by high-speed collisions and impacts, thereby improving the reliability and durability of the magnetic structure.

[0024] The magnetic attraction assembly 3 also includes a first positioning assembly 35, which is used to detachably fix the magnet 32 ​​to the mounting base 31. The first positioning assembly 35 includes a plurality of first screws 351 and a clamping plate 352 that are threadedly connected to the mounting base 31. The clamping plate 352 is attached to one side of the magnet 32. One end of the first screw 351 abuts against the clamping plate 352. The clamping plate 352 is designed with an L-shaped structure. The side of the magnet 32 ​​near the clamping plate 352 is provided with a matching L-shaped groove.

[0025] The magnet 32 ​​is placed inside the mounting base 31, and the clamping plate 352 is inserted into the L-shaped groove of the magnet 32. The first screw 351 is tightened, and its end abuts against and pushes the clamping plate 352. The clamping plate 352 then presses the magnet 32 ​​against the mounting base surface of the mounting base 31, thus firmly clamping the magnet 32 ​​onto the mounting base 31. The abutment clamping method avoids damage to the magnet 32 ​​and facilitates quick assembly and disassembly, improving the efficiency of disassembly, assembly, and subsequent maintenance or replacement.

[0026] The magnetic suction assembly 3 also includes a limiting assembly 38, which is used to detachably fix the mounting base 31 to the corresponding window frame 1 or window sash 2. The limiting assembly 38 includes a slot 382 opened on the side of the mounting base 31, a block 381 inserted into the slot 382, ​​and a second screw 383 provided on the side of the mounting base 31 and the slot 382 and opposite to the slot 382. The block 381 is fixed to the corresponding window frame 1 or window sash 2, and the second screw 383 is threadedly connected to the corresponding window frame 1 or window sash 2.

[0027] During installation, the mounting base 31 is embedded in the mounting groove of the window frame 1 or window sash 2. The mounting base 31 moves laterally, causing the slot 382 and the locking block 381 to engage, thus achieving lateral positioning of the mounting base 31. Then, the second screw 383 is tightened, with its end abutting against the surface of the mounting base 31, allowing the mounting base 31 to be easily detached and fixed to the window frame 1 or window sash 2. This simplifies installation and removal, and facilitates subsequent maintenance or replacement of the magnet 32 ​​inside the mounting base 31.

[0028] In some specific implementation plans, such as Figure 5 As shown, the magnetic assembly 3 also includes a heat insulation layer 34, preferably made of aerogel, located on the back of the mounting base 31. Generally, the window sash 2 is mostly closed to meet requirements for security, heat insulation, sound insulation, and privacy. Placing the heat insulation layer 34 on the side of the magnet 32 ​​closest to the external environment can effectively block the thermal shock of outdoor temperature changes to the magnet 32, thus protecting the performance of the magnet 32.

[0029] In some specific implementation plans, such as Figure 3 , Figure 4 and Figure 5 As shown, the magnetic component 3 also includes a protective film 37, which is peelably attached to the working surface of the magnet 32. The protective film 37 includes a thin film layer and a pressure-sensitive adhesive layer disposed on the thin film layer. The thin film layer can be made of PET (polyethylene terephthalate) or PE (polyethylene) film, and the edges of the protective film have pre-reserved areas without adhesive, forming a tear-off part for easy gripping. By attaching the protective film 37 to the working surface of the magnet 32, the magnet 32 ​​is kept protected during the transportation, installation, and decoration of doors and windows, preventing scratches, cement, paint, and other contaminants from affecting the magnetic attraction effect.

[0030] Magnet 32 ​​is a neodymium iron boron permanent magnet, whose strong magnetic field and stable magnetism ensure the adsorption and adhesion effect. Nickel plating or epoxy resin coating is applied to the surface of magnet 32 ​​to prevent corrosion.

[0031] In some specific implementation plans, such as Figure 3 and Figure 5 As shown, both the first screw 351 and the second screw 383 have hexagonal grooves 4 at one end, facilitating the use of tools to rotate them. The end of the first screw 351 with the hexagonal groove 4 is flush with or slightly lower than the outer surface of the mounting base 31, preventing the protruding first screw 351 from affecting the fit of the mounting base 31. The end of the second screw 383 with the hexagonal groove 4 is flush with or slightly lower than the outer surface of the corresponding window frame 1 or window sash 2, preventing the protruding second screw 383 from affecting the closing of the window sash 2.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: On the side where the window frame 1 and window sash 2 close towards each other, a mounting groove is pre-cut, and the magnetic suction assembly 3 is embedded inside the mounting groove. The magnetic suction assembly 3 has a built-in magnet 32, and a yoke layer 33 made of magnetically conductive material (such as low carbon steel) is set between the back of the magnet 32 ​​(i.e. the side facing away from the working surface) and the mounting base 31, so that the magnetic lines of force are efficiently guided and concentrated, enhancing the actual attraction effect and improving the reliability of use.

[0033] Furthermore, an elastic buffer pad 36 is provided on the working surface (adsorption and contact surface) of the magnet 32. The elastic buffer pad 36 can be made of a weather-resistant elastic material (such as rubber, silicone, or TPE), and its surface is slightly higher than the surface of the magnet 32 ​​after installation. When the window sash 2 is close, the elastic buffer pad 36 makes contact first, and there is still a small gap between the magnets 32. As the closing action continues, the elastic buffer pad 36 is compressed and undergoes elastic deformation to provide a buffering effect, during which the final gap between the magnets 32 is smoothly reduced. When the elastic buffer pad 36 is compressed to the end of its stroke, the magnets 32 are at the optimal working distance for basic contact, ensuring a stable adsorption force to seal the window sash 2. By setting the elastic buffer pad 36, the originally rigid, high-speed collision adsorption is avoided, reducing the damage to the magnets 32 caused by high-speed collisions and impacts, thereby improving the reliability and durability of the magnetic structure.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
