Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy door and window technology, and particularly relates to a sound-insulating and noise-reducing aluminum alloy door and window and a method for adjusting noise and ventilation. Background Technology

[0002] Aluminum alloy doors and windows are windows made of aluminum alloy as the frame material, with window sashes installed on the window frame, including window sashes installed by sliding or hinged means, and tempered glass panels on the window sashes to allow light to pass through.

[0003] Aluminum alloy doors and windows use lightweight aluminum alloy as the frame, resulting in a lightweight, simple, and aesthetically pleasing overall structure. Therefore, aluminum alloy doors and windows are widely used in industry, primarily for building window frames.

[0004] Therefore, the demand for aluminum alloy doors and windows in the industry is relatively large, and improving the technology in the production process is the key to improving the production efficiency and product quality of aluminum alloy doors and windows.

[0005] Based on this, Chinese Patent Publication No. CN119041816A discloses an environmentally friendly noise-reducing aluminum alloy door and window. The main structure of this door and window includes: a door and window fixing frame, a window sash frame, a glass mounting bracket, sound-insulating sealing strips, and soundproof glass. The window sash frame is located inside the door and window fixing frame, and is fitted onto the outside of the soundproof glass. This technical solution discloses a window structure that allows for both upper and lower opening methods, forming a flat structure with the window sash frame and soundproof glass that can be used to place items or for seating, increasing the usability of the door and window. The guardrail can be extended inside the door and window fixing frame for protection, and can also be retracted when the window sash frame is closed. This allows the window sash frame to flip upwards and remain in a parallel open state, ensuring stable fixation when the door and window are open. The positioning buckles provide sunshade when the window sash frame is open and when it is closed.

[0006] However, in practical applications, it has been found that the noise reduction capability of aluminum alloy doors and windows is limited. For buildings located in noisy environments, such as those near train stations and bus stations, installing aluminum alloy doors and windows cannot effectively reduce the noise from the external environment. The specific reason is that the noise from the external environment is very loud, while the sound insulation capability of the window structure is fixed and limited.

[0007] Therefore, in actual operation, sound insulation is increased by adding soundproof glass panels. However, based on the principle of sound propagation, sound is transmitted from the outside to the inside through the thin aluminum alloy frame material, resulting in relatively high indoor noise even after installing multiple layers of soundproof glass panels. Furthermore, the aluminum alloy frame structure is an indispensable mechanical structure for aluminum alloy windows.

[0008] Therefore, in practical applications, completely sealing the window opening with a large, single piece of glass firstly renders the window's (sliding or moving) function completely ineffective, and secondly, it completely prevents ventilation between the inside and outside. Thus, sacrificing ventilation for noise reduction in this way is not very practical in real-world use.

[0009] Noise is often louder during the day and quieter or even absent at night. Therefore, if the window structure cannot be flexibly adjusted between noise reduction and ventilation according to the characteristics of the noise environment, the practicality of the window will inevitably be greatly reduced. Summary of the Invention

[0010] Based on the above background, the purpose of this invention is to provide a soundproof and noise-reducing aluminum alloy door and window, and a method for regulating noise and ventilation.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: A soundproof and noise-reducing aluminum alloy door and window, comprising a sliding window body installed in the door and window opening; The soundproof and noise-reducing aluminum alloy doors and windows also include a window cover mechanism covering the outside of the door and window openings. The window cover mechanism includes a frame and soundproof glass installed inside the frame. The top of the window cover mechanism is equipped with a translation structure for moving the frame. The translation structure includes several racks fixedly installed at the top of the frame. The translation structure also includes gears that mesh with the racks. The gears are fixedly connected to each other through gear shafts. The gear shaft is fixedly installed on the wall outside the window opening via a gear shaft bracket; The gear shaft is driven by a sprocket transmission structure; The window cover mechanism also includes a support pulley structure that supports the rolling of the window at the bottom of the frame. During the translation of the window, the movement is supported by the support pulley structure. The soundproof and noise-reducing aluminum alloy doors and windows also include an air guiding mechanism. After the window cover mechanism is pushed and a ventilation gap is formed between it and the door and window opening, the air guiding mechanism guides the airflow through the ventilation gap into the room. The air guiding mechanism includes air guiding plates installed on the front and rear sides of the frame respectively. The angle of the air guiding plate on the vertical plane is adjusted by a first adjustment structure, and the angle of the air guiding plate on the horizontal plane is adjusted by a second adjustment structure. The adjustment of the angle on the vertical plane and the angle on the horizontal plane increases the airflow into the room.

[0012] Preferably, the translation structure includes racks fixedly installed on the front and rear sides of the top of the frame; Gears with meshing racks are fixedly installed on the front and rear sides of the gear shaft, and the gear shaft frame includes a bearing frame part rotatably connected to the gear shaft. A fixed connecting frame part is fixedly installed on the bearing frame part and the fixed connecting frame part is fixedly installed on the wall.

[0013] Preferably, a plurality of limiting sliding structures are installed at the top and bottom of the frame; The limiting sliding structure includes a slide seat fixedly installed on the frame, a supporting slide body slidably connected inside the slide seat, the inner end of the supporting slide body being fixedly installed on the wall outside the door and window opening, and a partition part integrally formed on the outer end of the supporting slide body.

[0014] Preferably, the sprocket drive structure includes driven sprockets that are fixedly installed at both ends of the gear shaft; The sprocket drive structure also includes a sprocket motor that is connected to the driven sprocket. A driving sprocket is fixedly installed on the output shaft of the sprocket motor. The driving sprocket and the driven sprocket are connected by a chain drive.

[0015] Preferably, the supporting pulley structure includes several supporting tracks that are respectively fixedly installed on the outer wall of the door and window openings, and several traveling rollers that support the rolling on the supporting tracks are installed at the bottom of the frame.

[0016] Preferably, the air guide plate is trapezoidal in shape; The length of the outer end face of the air guide plate is less than the length of the inner end face of the air guide plate; The air guide plate is installed at the center of the side wall of the frame.

[0017] Preferably, the first adjustment structure includes a vertically arranged U-shaped adjustment frame, and the top and bottom of the air guide plate are respectively fixedly connected with hinged screws threaded to the U-shaped adjustment frame.

[0018] Preferably, a drive ring handle for driving the air guide plate to rotate is fixedly connected to the air guide plate.

[0019] Preferably, the second adjustment structure is an angle adjustment motor, and the output shaft of the angle adjustment motor is fixedly mounted on the U-shaped adjustment frame; The top and bottom of the angle adjustment motor are respectively fixedly connected to motor brackets, and the motor brackets are fixedly installed on the side wall of the frame.

[0020] This invention also discloses a method for adjusting noise and ventilation in the aforementioned sound-insulating and noise-reducing aluminum alloy doors and windows, comprising the following steps: (1) Noise adjustment: Adjust the distance between the window cover mechanism and the door / window opening according to the level of outdoor noise. The adjustment steps are as follows: In cases of high noise levels, the gears on the translation structure drive the rack on the frame through the sprocket transmission structure, pushing the frame to move closer to and completely cover the outer walls of the door and window openings. The window cover mechanism completely seals and covers the outside of the door and window openings to isolate noise to the maximum extent. During the movement of the frame, the frame rolls using the support pulley structure installed at the bottom; (2) Ventilation control methods: When outdoor noise levels are low, the steps to adjust indoor and outdoor ventilation are as follows: Driven by a sprocket transmission structure, the distance between the frame and the door / window openings increases, and the angle of the air guide vanes is adjusted to divert outdoor airflow into the room. The method is as follows: Based on the direction of airflow, the first adjustment structure initially adjusts the angle of the air guide plate on the vertical plane, and the second adjustment structure adjusts the angle of the air guide plate on the horizontal plane. After the coordinated adjustment of the first and second adjustment structures, the air guide plate guides the airflow into the room to the maximum extent.

[0021] The present invention has the following beneficial effects: 1. The present invention forms a window cover mechanism that can be adjusted according to the noise level. The window cover mechanism cooperates with the inner sliding window body by covering the outside of the door and window opening. The outer window cover mechanism completely covers the aluminum alloy frame on the inner sliding window body in the glass cover. The advantages are: firstly, the noise reduction method of the glass cover is an innovative sound insulation method, which has not been improved in the existing technology. This method is suitable for buildings with very high environmental noise, especially such as those near stations.

[0022] 2. The cover is adjustable, which means that in quiet environments such as at night, the gaps in the cover can be increased to allow airflow into the room. This is especially useful in hot weather when the outside world is relatively quiet at night, thus increasing indoor and outdoor ventilation.

[0023] 3. During the adjustment of the window cover mechanism, a gear shaft, gear, and rack structure are used to horizontally push the heavy frame. In this process, the self-locking characteristic of the gear and rack structure is utilized to keep the frame stationary, especially in strong winds. Simultaneously, the transmission through the sprockets on both sides distributes the transmission load and achieves synchronous transmission on both sides, increasing the stability of the horizontal movement.

[0024] 4. By using a supporting pulley structure, the safety of moving the frame cover is greatly improved. Because the frame cover is too heavy, moving it while suspended in the air would not only result in poor stability but also a high risk factor. During operation, as the frame cover moves, the traveling rollers roll on the supporting rails. This method not only increases the safety and stability of the movement but also enhances the flexibility of the frame cover during relocation.

[0025] 5. During the movement of the frame cover, a limiting sliding structure is used. The sliding block and supporting sliding body further maintain the stability of the frame cover. This method acts as a safety measure, preventing the frame cover from falling from a height in the event of a malfunction, such as chain breakage, gear or rack misalignment, etc., thus maintaining the stability of the frame cover.

[0026] 6. The air guiding mechanism includes air guide plates installed on the front and rear sides of the frame respectively. In order to increase the effect of indoor and outdoor air exchange according to the airflow direction, the angle of the air guide plates is adjusted. Specifically, the first adjustment structure and the second adjustment structure are used to realize that the air guide plates introduce airflow into the room at the optimal guiding angle.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0033] Example 1 like Figure 1-10 As shown, a soundproof and noise-reducing aluminum alloy door and window includes a sliding window body 1 installed in the door / window opening 2. Specifically, the sliding window body 1 has the same structure as the conventional sliding window body 1 disclosed in the prior art, including an aluminum alloy window frame 11 fixedly installed in the door / window opening 2 and a sliding window sash 12 installed in the aluminum alloy window frame.

[0034] In practical applications, noise can easily travel from the outdoor environment to the indoor environment through the aluminum alloy metal frame, which means that even increasing the number of tempered glass layers cannot significantly reduce noise during actual operation.

[0035] Therefore, the present invention adopts the following improvement method to form a window cover mechanism that can be adjusted according to the noise level. The window cover mechanism cooperates with the inner sliding window body 1 by covering the outside of the door and window opening 2. The outer window cover mechanism completely covers the aluminum alloy frame on the inner sliding window body 1 in the glass cover. The advantages are: firstly, the noise reduction method of the glass cover is the first of its kind for sound insulation. No existing technology has improved this method. This method is suitable for buildings with very high environmental noise, especially such as those near stations.

[0036] Secondly, the cover is adjustable, which means that in quiet environments such as at night, the gaps in the cover can be increased to allow airflow into the room. This is especially useful in hot weather when the outside world is relatively quiet at night, thus increasing indoor and outdoor ventilation.

[0037] Specifically, the window cover mechanism covers the outside of the door / window opening 2.

[0038] The specific structure of the window cover mechanism is as follows: The window enclosure mechanism includes a frame and soundproof glass 31 installed in the frame 3 (the frame 3 is also made of aluminum alloy and its size is larger than that of the door and window opening 2. When the frame 3 covers the wall outside the door and window opening 2, the metal frame 3 transmits noise through the wall structure. Since the wall is a concrete structure, it can effectively reduce noise. The metal frame of the sliding window body covered in the frame 3 is completely covered in the glass cavity, thus effectively preventing noise from being transmitted inside and outside the sliding window body).

[0039] Example 2 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 1, in actual operation, since the frame 3-soundproof glass is often large in size and therefore quite heavy, in order to move the heavy frame 3-soundproof glass structure in a very stable manner during actual operation, a translation structure 4 for moving the frame 3 is installed on the top of the above-mentioned window cover mechanism.

[0040] Specifically, the translation structure 4 includes two racks 41 (set at intervals) fixedly installed at the top of the frame 3. The translation structure 4 also includes two gears 42 that mesh with the racks 41 respectively, and the gears 42 are fixedly connected by a gear shaft 441. Specifically, the gear shaft 441 is fixedly installed on the wall outside the window opening by a wheel and axle bracket.

[0041] Specifically, the axle frame includes a bearing bracket 4411 (with a bearing installed on the bearing bracket) rotatably connected to the gear shaft 441. Meanwhile, the gear shaft 441 is fixedly installed according to the existing anchoring method. The bearing bracket 4411 is fixedly installed with a fixed connecting bracket (using a steel frame), and the fixed connecting bracket (not shown in the figure) is fixedly installed on the wall.

[0042] During operation, the gear 42 structure mounted on the gear shaft 441 is always meshed with the rack 41, allowing the heavy frame 3 to be horizontally pushed by the gear 42 and rack 41 structure. In this process, the self-locking characteristic of the gear 42 and rack 41 structure is utilized to keep the frame 3 stationary, especially in situations with strong winds.

[0043] Example 3 like Figure 1-10 As shown, in this embodiment, based on the structure of Embodiment 2, the gear shaft 441 is driven by a sprocket drive structure. Specifically, the sprocket drive structure includes driven sprockets 42 fixedly installed at both ends of the gear shaft 441; the sprocket drive structure also includes a sprocket motor 43 that is connected to the driven sprockets 42, and a driving sprocket is fixedly installed on the output shaft of the sprocket motor 43. The driving sprocket and the driven sprockets 42 are connected by a chain drive.

[0044] During operation, the high self-locking characteristics of the chain and sprocket are utilized through chain drive to achieve high stability during transmission and ensure the stability of the frame 3 movement.

[0045] During operation, the driven sprocket motor 43 drives the driven sprockets 42 and the driving sprockets on both sides. By arranging the sprocket motor 43, driven sprockets 42 and driving sprockets on both sides, the load of pushing is distributed to the two chain drive mechanisms, thereby further increasing the stability of pushing the heavy frame 3.

[0046] Example 4 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 3, a motor mounting bracket is installed on the top of the sprocket motor 43 to fix the sprocket motor 43 to the wall. The motor mounting bracket includes a mounting plate 432 fixedly mounted on the sprocket motor 43, and a hanger 433 with an L-shaped structure is fixedly connected to the mounting plate 432. A diagonal bracing structure is welded to the hanger 433 to increase its stability. The inner end of the hanger is mounted on the wall. A bearing bracket 431 is also mounted on the output shaft of the sprocket motor 43, and the bearing bracket 431 is fixedly mounted on the mounting plate 432.

[0047] Example 5 like Figure 1-10 As shown, based on the structure of embodiment 4, the above-mentioned window cover mechanism further includes a support pulley structure 5 that supports the rolling at the bottom of the frame 3. During the translation of the window, the movement is supported by the support pulley structure 5.

[0048] Because the frame 3 is too bulky, its stability is very poor and the risk factor is high when it is moved in a suspended manner. Therefore, the support pulley structure 5 greatly increases the safety of the frame 3 during movement.

[0049] Specifically, the support pulley structure 5 includes several support rails 52 that are fixedly installed on the outer wall of the door and window openings 2. The bottom of the frame 3 is equipped with several traveling rollers that support the rollers that roll on the support rails 52 (the traveling rollers include wheel frames 51 that are fixedly installed at the bottom of the frame 3 and roller bodies 511 that are rotatably connected to the wheel frames).

[0050] During operation, when the frame 3 moves, the rollers 511 of the traveling rollers roll on the support rail 52. This not only increases the safety and stability of the movement, but also increases the flexibility of the frame 3 during the movement.

[0051] Example 6 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 5, a plurality of limiting sliding structures 6 are respectively installed on the top and bottom of the frame 3; the limiting sliding structure 6 includes a slide seat 61 fixedly installed on the frame 3, a supporting slide body 62 is slidably connected in the slide seat 61, the inner end of the supporting slide body 62 is fixedly installed on the wall outside the door and window opening 2, and the outer end of the supporting slide body 62 is integrally formed with a partition.

[0052] The above-described method ensures the stability of the frame 3 during its movement, further maintained by the slide block 61 and supporting slide body 62. This mechanism acts as a safety measure, preventing the frame 3 from falling from a height, such as in the event of chain breakage, gear 42 misalignment, or rack 41 misalignment.

[0053] Example 7 like Figure 1-10 As shown, based on the structure of Embodiment 6, in order to adjust ventilation according to the environmental noise situation during actual operation, such as when there is no noise at night, the above-mentioned soundproof and noise-reducing aluminum alloy doors and windows also include a wind guide mechanism 7. After the window cover mechanism is pushed and a ventilation gap is formed between it and the door and window opening 2, the airflow is guided through the ventilation gap into the room by the wind guide mechanism 7.

[0054] Example 8 like Figure 1-10 As shown, this embodiment, based on the structure of embodiment 7, specifically discloses the structure of the air guiding mechanism 7. Specifically, the air guiding mechanism 7 includes air guiding plates 71 respectively installed on the front and rear sides of the frame 3. The air guiding plates 71 are made of aluminum alloy. Similar to existing methods, to improve the structural stability of the air guiding plates 71, reinforcing ribs are welded to the top and bottom of the air guiding plates 71 to increase their resistance to wind deformation.

[0055] Meanwhile, during operation, in order to increase the effect of indoor and outdoor air exchange according to the airflow direction, the angle of the air guide plate 71 is adjusted so that the air guide plate 71 introduces the airflow into the room at the optimal guiding angle.

[0056] Example 9 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 8, the air guide plate 71 is adjusted at its angle on the vertical plane by the first adjustment structure, and at its angle on the horizontal plane by the second adjustment structure. By adjusting the angle on the vertical plane and the angle on the horizontal plane, the airflow into the room is increased.

[0057] Specifically, the air guide plate 71 is trapezoidal in shape; that is, the length of the outer end face of the air guide plate 71 is less than the length of the inner end face of the air guide plate 71; so that the airflow is guided by the trapezoidal air guide plate 71, and the airflow gradually flows from the outside of the narrow air guide plate 71 to the inside of the wide air guide plate 71, so that during the operation, the trapezoidal air guide plate 71 guides the airflow in with the maximum amplitude.

[0058] The aforementioned air guide plate 71 is installed at the center of the side wall of the frame 3.

[0059] The aforementioned first adjustment structure includes a vertically arranged U-shaped adjustment frame 72. The top and bottom of the air guide plate 71 are respectively fixedly connected to hinge screws 711 threaded onto the U-shaped adjustment frame 72. The hinge screws 711 have a certain length, so that during operation, rotating the air guide plate 71 causes the hinge screws 711 at the top and bottom of the air guide plate 71 to rotate relative to the U-shaped adjustment frame 72. Under the action of the threaded force, the air guide plate 71 remains stationary. To facilitate adjusting the angle of the air guide plate 71, a drive ring handle 74 is fixedly connected to the air guide plate 71 to drive its rotation.

[0060] During operation, as the air is guided, the frame 3 moves along the door and window opening 2. At this time, the sliding window is opened, and the people inside can extend their hands from the door and window opening 2 and grab the drive ring handle 74 to drive the air guide plate 71 to adjust the angle. Alternatively, tools such as a rod with hooks can be used for assistance.

[0061] Example 10 like Figure 1-10 As shown, based on the structure of embodiment 9, in order to further adjust the angle of the air guide plate 71 according to the airflow direction, the second adjustment structure includes an angle adjustment motor 73. The output shaft of the angle adjustment motor 73 is fixedly installed on the U-shaped adjustment frame 72 (in order to increase the connection stability of the output shaft, the center part of the side wall of the U-shaped adjustment frame 72 is fixedly connected to the output shaft support 721); the top and bottom of the angle adjustment motor 73 are respectively fixedly connected to the motor bracket 731, and the motor bracket 731 is fixedly installed on the side wall of the frame 3.

[0062] During operation, the operator adjusts the angle of the air guide plate 71 by using the angle adjustment motor 73. Specifically, the air guide plate 71 and the U-shaped adjustment frame 72 are adjusted synchronously under the drive of the angle adjustment motor 73. During the adjustment process, the operator can complete the adjustment by determining the posture of the air guide plate 71 based on the perceived airflow.

[0063] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.

The method is as follows: Based on the direction of airflow, the first adjustment structure initially adjusts the angle of the air guide plate on the vertical plane, and the second adjustment structure adjusts the angle of the air guide plate on the horizontal plane. After the coordinated adjustment of the first and second adjustment structures, the air guide plate guides the airflow into the room to the maximum extent.
