Description

Technical Field

[0001] This invention relates to the technical field of soundproof windows, and in particular to a highly sound-insulating, sealed soundproof structure. Background Technology

[0002] In the field of building doors and windows, with the acceleration of urbanization and people's increasing demands for living quality, the sound insulation performance of building windows has become an important indicator for measuring building quality. Especially in noise-sensitive areas such as around airports, along elevated roads, and in bustling commercial districts, the sound insulation capability of windows directly affects the quality of the indoor acoustic environment and the comfort of living. Currently, most soundproof windows on the market use structures such as double-glazed windows, multi-layered glass, or laminated glass. By increasing the number of glass layers or changing the glass thickness, the sound insulation effect is improved, which can reduce the intrusion of external noise to a certain extent.

[0003] However, in practical applications, existing soundproof windows still have many unresolved problems. First, the hinge structure of traditional inward-opening windows is mostly a rotating synchronous micro-translation structure, which easily leads to uneven stress on the sealing strip and insufficient local compression, forming a sound wave leakage channel.

[0004] Secondly, when traditional doors and windows are closed, there are often obvious uneven steps between the inner frame and the outer window frame. This structure is prone to generating eddies and wind noise when outdoor airflow passes through, and also increases the risk of sound wave diffraction leakage. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing high sound insulation sealed sound insulation structures, the present invention is proposed.

[0007] Therefore, the problem to be solved by this invention is how to solve the problem of uneven stress on the sealing strip and the obvious uneven steps between the inner frame and the outer window frame, which easily leads to eddies and wind noise.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high sound insulation and sealing structure, comprising: an outer window frame, which is fixedly installed; an inner opening frame, which is installed inside the outer window frame, and a plurality of soundproof glass panels are installed inside the inner opening frame; two sets of movable hinges, which are respectively installed at both ends of one side of the inner opening frame, including a rotating plate, which is fixedly connected to the inner opening frame, a guide shaft is installed at the bottom end of the rotating plate, a sliding frame is slidably installed at the bottom end of the guide shaft, and a pushing component is installed inside the sliding frame; a locking component, including sliding grooves opened at both ends of the inner opening frame, a locking plate installed inside the sliding grooves, a locking groove opened at the position corresponding to the locking plate on the outer window frame; and a linkage component installed inside the inner opening frame, the linkage component being used to control the locking plates on both sides to simultaneously insert into or slide out of the locking grooves, for locking the outer window frame and the inner opening frame.

[0009] As a preferred embodiment of the high sound insulation and sealed sound insulation structure of the present invention, the outer window frame is provided with a partition layer inside, the partition layer is filled with sound-absorbing cotton, and the outer window frame is also provided with multiple cavities.

[0010] As a preferred embodiment of the high sound insulation and sealing structure of the present invention, the outer periphery of the outer window frame is provided with a protective plate, a rubber pad is provided at the center of the bottom end of the protective plate, and through pipes are provided on both sides of the bottom end of the rubber pad. The center of the rubber pad is fixedly connected to the protective plate.

[0011] As a preferred embodiment of the high sound insulation and sealed sound insulation structure of the present invention, the contact surface between the sound insulation glass and the inner frame is provided with a plurality of square small holes, a sealing strip is provided on the outer periphery of the inner frame, the interior of the sealing strip is hollow, and the adjacent sound insulation glass is filled with laminated adhesive.

[0012] As a preferred embodiment of the high sound insulation and sealed sound insulation structure of the present invention, the inner wall of the outer window frame and the outer wall of the inner opening frame are both stepped.

[0013] As a preferred embodiment of the high sound insulation and sealed sound insulation structure of the present invention, the pushing component includes a telescopic rod, one end of which is fixedly connected to the inner wall of the sliding frame, and the other end of which is fixedly provided with a rotating ring. The guide shaft is inserted into the inside of the rotating ring and is rotatably connected by a bearing. The inside of the outer window frame is provided with a fixing groove for installing the sliding frame.

[0014] As a preferred embodiment of the high sound insulation and sealed sound insulation structure of the present invention, the linkage component includes a rotating cavity, which is opened inside the inner frame. A linkage disk is rotatably arranged inside the rotating cavity. A receiving groove is opened on the outer periphery of the linkage disk. Two rotating shafts are symmetrically arranged inside the receiving groove. A linkage rod is rotatably arranged on each of the two rotating shafts. A piston column is provided at the end of the linkage rod away from the rotating shaft.

[0015] As a preferred embodiment of the high sound insulation and sealing sound insulation structure of the present invention, the linkage component further includes a guide pipe connected to the sliding groove, a piston rod slidably disposed inside the guide pipe, a closed frame disposed at one end of the guide pipe, the closed frame being connected to the sliding groove, an isolation plate disposed inside the closed frame, and a guide hole disposed at the center of the isolation plate.

[0016] As a preferred embodiment of the high sound insulation and sealing structure of the present invention, the bottom end of the locking plate is set with an inclined surface, and the inside of the locking groove opposite to the locking plate is also set with an inclined surface. When the locking plate moves downward and is inserted into the inside of the locking groove, the two inclined surfaces press against each other to push the inner opening frame to move inward toward the inside of the outer window frame.

[0017] As a preferred embodiment of the high sound insulation and sealing sound insulation structure of the present invention, wherein: after the inner opening frame and the outer window frame are closed, the side of the inner opening frame facing the outside is flush with the outer window frame.

[0018] The beneficial effects of this invention are: 1. By using the composite motion hinge structure of the outer window frame and the inner opening frame, the traditional single rotational motion is decomposed into a composite motion of rotation and translation. The linkage component drives the locking plates on both sides to move synchronously. With the inclined surface cooperation structure of the locking plate and the locking groove, the vertical movement is converted into a horizontal thrust on the inner opening frame during the locking process. This forces the inner opening frame to translate into the inner window frame, so that the stepped inner and outer frames fit tightly together and the hollow sealing strip reaches the maximum compression, forming a progressive closing effect from pre-sealing to complete sealing.

[0019] 2. The design, with the inner frame flush with the outside after closure, eliminates the uneven steps of traditional doors and windows, effectively reducing wind noise. In terms of sound insulation, the alternating sound-absorbing cotton and cavities inside the outer window frame form a multi-layered impedance composite structure, achieving effective sound insulation over a wide frequency range. The square holes on the contact surface between the soundproof glass and the inner frame form a Helmholtz resonance cavity, effectively absorbing low-frequency noise. The interlayer between adjacent soundproof glass panes suppresses glass resonance through damping characteristics, improving the isolation effect for mid-to-high frequency noise. The installation and sealing structure between the outer window frame and the window opening uses an arched rubber pad combined with secondary injection of foam adhesive. The continuous resilience of the arched structure compensates for deviations in window opening dimensions, forming multiple elastic sealing barriers to block sound bridge transmission, further improving the sound insulation effect.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a high sound insulation and sealing structure. The high sound insulation and sealing structure includes an outer window frame 1, an inner opening frame 2, a movable hinge 3, and a locking component 4. The combined movement of the outer window frame 1 and the inner opening frame 2 is decomposed into a combined movement of rotation and translation by the movable hinge 3. During the process of locking the outer window frame 1 and the inner opening frame 2, the inner opening frame 2 is forced to translate into the inner side of the outer window frame 1, so that the stepped inner and outer frames fit tightly together and the hollow sealing strip 5 reaches the maximum compression, forming a progressive closing effect from pre-sealing to complete sealing.

[0035] Specifically, the outer window frame 1 is fixedly installed, and the inner opening frame 2 is located inside the outer window frame 1. Several pieces of soundproof glass 21 are installed inside the inner opening frame 2. The outer window frame 1 is fixed to the window opening in the wall by expansion bolts, forming a stable load-bearing base. The inner opening frame 2 is movably connected to the outer window frame 1 by a hinge 3, enabling inward opening and closing. The several pieces of soundproof glass 21 adopt a laminated and hollow composite structure, with alternating laminated and vacuum layers, allowing the soundproof glass 21 to absorb low-frequency noise and block high-frequency noise, significantly improving the soundproof glass 21's ability to block both low and high-frequency noise. It is fixed inside the inner opening frame 2 by a pressure strip.

[0036] Specifically, the movable hinge 3 is provided in two sets, respectively located at both ends of one side of the inner frame 2. It includes a rotating plate 31, which is fixedly connected to the inner frame 2. A guide shaft 32 is provided at the bottom end of the rotating plate 31. A translation frame is slidably provided at the bottom end of the guide shaft 32. A pushing component 33 is provided inside the translation frame. The rotating plate 31 is fixed to the side of the inner frame 2 by bolts. The guide shaft 32 is vertically fixed to the bottom end of the rotating plate 31. The lower end of the guide shaft 32 is inserted into the translation frame and can slide along the guide groove of the translation frame. The pushing component 33 is installed inside the translation frame and is movably connected to the guide shaft 32. The translation frame is fixedly embedded in the fixing groove 333 opened at the corresponding position of the outer window frame 1.

[0037] When the inward-opening frame 2 is opened and closed, the guide shaft 32 can slide within the translation frame, while pushing the component 33 to provide a restoring force. This allows the inward-opening frame 2 to automatically adapt to the relative position changes with the outer window frame 1 during the opening and closing process, and provides an auxiliary translation thrust when opening. This hinge structure decomposes the single rotational motion of the traditional hinge into a composite motion of rotation and translation, effectively solving the friction and jamming problem caused by the interference of the rotation trajectory between the sealing strip 5 and the frame when the inward-opening door and window is closed. At the same time, it provides the degree of freedom of movement for the translation and compression required when locking, significantly improving the smoothness of the opening and closing feel and the reliability of the seal.

[0038] Specifically, the locking component 4 includes sliding grooves 41 at both ends of the inner frame 2, with locking plates 42 inside the sliding grooves 41. A locking groove 43 is provided at a position corresponding to the locking plate 42 on the outer window frame 1. A linkage component 44 is also provided inside the inner frame 2. The linkage component 44 controls the locking plates 42 on both sides to simultaneously insert into or slide out of the locking groove 43, thereby locking the outer window frame 1 and the inner frame 2. The sliding grooves 41 are symmetrically located at the upper and lower ends of the inner frame 2. The locking plates 42 are slidably fitted into the sliding grooves 41, with their outer ends extending or retracting. The locking grooves 43 are correspondingly located on the outer window frame 1 and can form a plug-in engagement with the locking plates 42.

[0039] The linkage component 44 is installed in the internal cavity 13 of the inner opening frame 2. When the handle is rotated, the linkage component 44 transmits the rotation torque of the handle to the locking plates 42 on both sides simultaneously, driving the locking plates 42 to extend along the sliding groove 41 and insert into the corresponding locking groove 43, or retract and unlock simultaneously. The linkage component 44 achieves the absolute synchronous movement of the locking plates 42 on both sides, avoiding the problem of one side not locking properly or getting stuck due to asynchronous operation of traditional multi-point locks. It ensures that the inner opening frame 2 is evenly stressed and has consistent locking force at both ends when closed, so that the sealing strip 5 is uniformly compressed along the entire circumference, eliminating local leakage gaps, improving the locking effect, and achieving the purpose of improving sealing and isolating external sound sources.

[0040] Example 2, refer to Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the outer window frame 1 has an internal partition layer 11 filled with sound-absorbing cotton 12, and the outer window frame 1 also has multiple cavities 13. The partition layer 11 fixes the sound-absorbing cotton 12 to the interior of the outer window frame 1, and the sound-absorbing cotton 12 and the multiple cavities 13 are arranged alternately to form a multi-layer impedance composite structure. When external sound waves enter the outer window frame 1, the sound waves are repeatedly refracted and attenuated between the cavities 13 and the sound-absorbing cotton 12. The sound-absorbing cotton 12 converts sound energy into heat energy and consumes it, while the multiple cavities 13 increase the number of reflections by changing the sound wave propagation path, thereby achieving effective broadband sound insulation.

[0042] Specifically, a protective plate 14 is provided on the outer periphery of the outer window frame 1. A rubber pad 15 is provided at the center of the bottom end of the protective plate 14, and through pipes 16 are provided on both sides of the bottom end of the rubber pad 15. The center of the rubber pad 15 is fixedly connected to the protective plate 14. The center of the rubber pad 15 is fixed to the protective plate 14, and the two sides are free ends. During installation, the two sides of the rubber pad 15 are pressed down to form a gap between it and the protective plate 14. After the foam is injected, an arched gap is naturally formed between the rubber pad 15 and the window opening. The through pipes 16 are connected to this arched gap for secondary injection of glue. The arched rubber pad 15 generates a continuous rebound force after being filled with foam, which can not only compensate for the deviation of the window opening size, but also form multiple elastic sealing barriers, effectively blocking the transmission of sound bridges and significantly improving the sound insulation performance between the outer window frame 1 and the wall.

[0043] Specifically, such as Figure 9 As shown, the contact surface between the soundproof glass 21 and the inner frame 2 has several small square holes 22. A sealing strip 5 is provided on the outer periphery of the inner frame 2. The sealing strip 5 is hollow inside, and the space between adjacent soundproof glass panes 21 is filled with adhesive. The small square holes 22 are located on the contact surface between the soundproof glass 21 and the inner frame 2, forming a Helmholtz resonant cavity structure together with the internal cavity 13, used to absorb low-frequency noise in a specific frequency band. The hollow sealing strip 5 is fitted onto the outer periphery of the inner frame 2, and when compressed, it emits... Pre-sealing is achieved through elastic deformation. Adhesive strips are provided at the edges between adjacent soundproof glass 21 to bond multiple soundproof glass 21 pieces together, so that a cavity can be formed between two adjacent soundproof glass 21. An adhesive layer and a vacuum layer are respectively provided in the adjacent cavities. The vacuum layer can significantly reduce the penetration of low-frequency noise, allowing the soundproof glass 21 to absorb external low-frequency noise. At the same time, the damping characteristics of the adhesive layer are used to suppress glass resonance, further improving the isolation effect of mid- and high-frequency noise.

[0044] Specifically, both the inner wall of the outer window frame 1 and the outer wall of the inner opening frame 2 are stepped. The stepped surfaces of the inner wall of the outer window frame 1 and the outer wall of the inner opening frame 2 cooperate with each other to form a multi-layered, tortuous sealing interface. In the closed state, the stepped structure causes the gap between the inner and outer frames to extend non-linearly, increasing the length and complexity of the sound wave leakage path. At the same time, it provides a multi-level compression contact surface for the sealing strip 5, effectively preventing sound waves from propagating in a straight line along the gap, and significantly improving airtightness and sound insulation performance.

[0045] Specifically, the pushing component 33 includes a telescopic rod 331. One end of the telescopic rod 331 is fixedly connected to the inner wall of the sliding frame, and the other end of the telescopic rod 331 is fixedly provided with a rotating ring 332. The guide shaft 32 is inserted into the inside of the rotating ring 332 and is rotatably connected through a bearing. The inner side of the outer window frame 1 is provided with a fixing groove 333 for installing the sliding frame. The sliding frame is installed in the fixing groove 333. One end of the telescopic rod 331 is fixed to the inner wall of the sliding frame, and the other end is connected to the guide shaft 32 through the rotating ring 332 and a bearing. The guide shaft 32 is fixed to the rotating plate 31. When the inner opening frame 2 is opened, the linkage component 44 cannot apply a pushing force to the locking plate 42. At this time, the guide shaft 32 can be pushed by the extension of the telescopic rod 331, so that the inner opening frame 2 moves away from the outer window frame 1. At this time, the inner opening frame 2 can be rotated open.

[0046] Specifically, the linkage assembly 44 includes a rotating cavity 441, which is located inside the inner frame 2. A linkage disc 442 is rotatably mounted inside the rotating cavity 441. A receiving groove 443 is formed on the outer periphery of the linkage disc 442. Two rotating shafts 444 are symmetrically arranged inside the receiving groove 443. Each rotating shaft 444 is rotatably connected to a linkage rod 445. A piston rod 446 is attached to the end of the linkage rod 445 away from the rotating shaft 444. The linkage disc 442 is rotatably connected to one end of the linkage rod 445 within the receiving groove 443 via the rotating shafts 444. The other end of the linkage rod 445 is fixedly connected to the piston rod 446. When the linkage disc 442 rotates, the rotating shafts 444 drive the linkage rod 445 to swing, converting the circular motion of the linkage disc 442 into the linear motion of the piston rod 446. The direction of power transmission is changed according to the direction of rotation, ensuring synchronous movement of the piston rods 446 on both sides.

[0047] Specifically, the linkage component 44 also includes a guide pipe 447 connected to the sliding groove 41. The piston rod 446 is slidably disposed inside the guide pipe 447. One end of the guide pipe 447 is provided with a sealing frame 448, which is connected to the sliding groove 41. An isolation plate 449 is provided inside the sealing frame 448, and a guide hole 4410 is provided at the center of the isolation plate 449. The guide pipe 447 seals the piston rod 446 and the sealing frame 448. The sealing frame 448 is connected to the sliding groove 41, and the guide hole 4410 on the isolation plate 449 forms a throttling structure. When the piston rod 446 slides in the guide pipe 447, the locking plate 42 is driven to move by oil through the guide hole 4410. The throttling effect of the guide hole 4410 makes the locking plate 42 move smoothly without impact, ensuring that the left and right locking plates 42 are inserted into or withdrawn from the locking groove 43 synchronously, thus achieving precise control of the linkage locking.

[0048] Specifically, the bottom end of the locking plate 42 is sloped, and the side of the locking groove 43 opposite to the locking plate 42 is also sloped. When the locking plate 42 moves downward and inserts into the locking groove 43, the two slopes press against each other, pushing the inner frame 2 to move inward toward the outer window frame 1. Both slopes can be equipped with ball bearings to reduce friction between them. The slope at the bottom of the locking plate 42 is opposite to the slope in the locking groove 43. When the locking plate 42 moves downward under the drive of the linkage component 44, the two slopes gradually contact and press against each other, converting the vertical movement of the locking plate 42 into a horizontal thrust on the inner frame 2, forcing the inner frame 2 to move inward toward the outer window frame 1. At the same time, the telescopic rod 331 is compressed and the sealing strip 5 is squeezed, realizing the linkage of locking and sealing, so that the sealing strip 5 reaches the maximum compression and completely fills the gap.

[0049] Specifically, after the inner frame 2 and the outer window frame 1 are closed, the side of the inner frame 2 facing the outside is flush with the outer window frame 1. When the locking plate 42 is fully inserted into the locking groove 43 and the inclined surface is pressed into place, the outer surface of the inner frame 2 and the outer surface of the outer window frame 1 are on the same plane. This flush structure eliminates the uneven steps that exist after the traditional doors and windows are closed, so that the outer surface of the window forms a complete and continuous plane, reducing the eddies and disturbances generated when the airflow passes by, effectively reducing wind noise, while improving the overall aesthetics and facilitating the cleaning of the facade.

[0050] In use, the outer window frame 1 is first fixedly installed inside the window opening. During installation, the two sides of the rubber pad 15 are pressed down to create a gap between the rubber pad 15 and the protective plate 14. Foam is then injected into this gap, naturally forming an arched gap between the rubber pad 15 and the window opening. Foam is then injected again into the arched gap through the tubes 16 on both sides of the bottom of the rubber pad 15. The foam expands evenly within the arched gap, causing the rubber pad 15 to fit tightly against the inner wall of the window opening. The arched structure generates a continuous rebound force after being compressed, which can compensate for the dimensional deviation of the window opening and form multiple elastic sealing barriers, effectively blocking the transmission of sound bridges, thereby significantly improving the sound insulation performance between the outer window frame 1 and the wall.

[0051] When the window needs to be closed, push the inner opening frame 2. The inner opening frame 2 rotates around the guide shaft 32 on the rotating plate 31 through the movable hinge 3, so that the inner opening frame 2 rotates to a position flush with the outer window frame 1. The hollow sealing strip 5 on the outer periphery of the inner opening frame 2 first contacts the outer window frame 1 during the closing process. Its internal hollow structure undergoes elastic deformation when squeezed, forming a pre-seal and filling the initial gap between the inner opening frame 2 and the outer window frame 1.

[0052] Subsequently, rotating the handle on the inner frame 2 drives the linkage disc 442 in the linkage assembly 44 to rotate within the rotating cavity 441. When the linkage disc 442 rotates, the two rotating shafts 444 in the receiving groove 443 drive the linkage rod 445 to move. The linkage rod 445 pulls the piston rod 446 to slide within the guide tube 447. The movement of the piston rod 446 is transmitted through the oil in the guide tube 447. Through the action of the isolation plate 449 and guide hole 4410 in the closed frame 448, the locking plate 42 in the sliding groove 41 moves synchronously. Since the bottom side of the locking plate 42 and the opposite side of the locking groove 43 are both With the inclined surfaces designed, as the locking plate 42 gradually inserts into the locking groove 43, the two inclined surfaces press against each other, generating a lateral thrust. This forces the inner opening frame 2 to move further into the outer window frame 1. This translation action compresses the telescopic rod 331, while simultaneously ensuring that the stepped structure of the inner opening frame 2 and the outer window frame 1 fits tightly together. It also further compresses the sealing strip 5, allowing the hollow sealing strip 5 to reach its maximum compression, completely filling all the gaps between them. When the inner opening frame 2 is fully closed, its side facing the outside remains flush with the outer window frame 1, avoiding the uneven surfaces that exist after traditional doors and windows are closed, and effectively reducing wind noise.

[0053] In the fully closed state, the soundproof glass 21 and the inner frame 2 form a Helmholtz resonant cavity structure through several small square holes 22, which can effectively absorb low-frequency noise. The laminated filling between adjacent soundproof glass 21 further enhances the isolation effect of mid-to-high frequency noise. At the same time, the sound-absorbing cotton 12 filled in the partition layer 11 inside the outer window frame 1 and the multiple cavities 13 together form a multi-layer impedance composite structure. Sound waves are repeatedly refracted and attenuated between the cavities 13 and the sound-absorbing cotton 12, achieving effective sound insulation over a wide frequency range. Through the sealing of the outer window frame 1 and the window opening by the arched rubber gasket 15, the inclined extrusion sealing of the locking plate 42 and the locking groove 43, the elastic sealing of the hollow sealing strip 5, and the multi-layer composite sound insulation structure, a comprehensive sealing and sound insulation system is formed from the installation interface to the closed interface, and from low frequency to high frequency.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
