Description

Technical Field

[0001] This invention belongs to the field of soundproof window technology, and in particular relates to a composite soundproofing high-strength soundproof aluminum alloy window. Background Technology

[0002] Aluminum alloy windows are made by processing aluminum alloy materials into aluminum alloy window frames, and then installing window sashes inside the aluminum alloy window frames. Subsequently, during the installation process, the aluminum alloy window frames are installed inside the window openings of the building structure.

[0003] Aluminum alloy windows are not only lightweight and inexpensive to manufacture, but also durable, making them widely used in various industries.

[0004] Aluminum alloy sliding windows are a type of window that opens and closes by pushing and pulling the window sash. Because of their sliding mechanism, sliding windows save space during opening and closing. They also offer a high level of aesthetic appeal when open or closed, making them popular for buildings with larger window openings.

[0005] However, for large aluminum alloy sliding windows, the number and size of the glass panels are relatively large, thus occupying a significant portion of the wall structure, resulting in poor sound insulation. This is especially true in buildings located in high-noise areas, such as bus stations and train stations, where noise pollution is severe. With large-area aluminum alloy sliding windows, noise penetrates through the glass panels and enters the room. Because the total area of ​​glass panels that easily transmit noise is larger, large sliding windows are less effective at sound insulation compared to smaller windows.

[0006] For example, Chinese Patent Publication No. CN213838355U discloses a modular aluminum alloy window, specifically comprising an aluminum alloy window frame assembly and a snap-fit ​​assembly. The aluminum alloy window frame assembly includes vertical and horizontal aluminum alloy window profiles, each with two profiles. The two horizontal aluminum alloy window profiles are respectively positioned at the ends between the two vertical profiles. The snap-fit ​​assembly includes corner blocks and elastic clips, with slots inside the corner blocks. By snapping the ends of the two sets of vertical and horizontal aluminum alloy window profiles into the slots inside the corner blocks, splicing and installation can be performed without cutting the ends of the vertical and horizontal aluminum alloy window profiles at a 45° angle, making the splicing of the vertical and horizontal aluminum alloy window profiles faster and more convenient.

[0007] While the aluminum alloy window structure disclosed in the above technical solution solves the technical problem of convenient window installation, it cannot effectively solve the problem of insufficient noise isolation.

[0008] Therefore, in actual work, the only solution to the above situation is to draw the curtains, but this reduces the amount of natural light.

[0009] In practice, it has been found that noise pollution sources often enter the room through the window structure from specific directions. Therefore, if large aluminum alloy sliding windows are fitted with adjustable partition windows to enhance noise isolation, specifically by pushing the partition window in the direction of the noise, not only can the noise be greatly reduced, but the cost is also low and space-saving because the partition is only partially blocked. However, most existing aluminum alloy sliding windows are single-frame structures, which cannot be adjusted to enhance noise isolation. Summary of the Invention

[0010] Based on the above background, the purpose of this invention is to provide a composite soundproof aluminum alloy window with high strength and sound insulation.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: A composite soundproof high-strength sound-insulating aluminum alloy window includes an aluminum alloy window body, which includes an aluminum alloy window frame, and a sliding window sash is assembled and connected within the aluminum alloy window frame. The composite soundproof high-strength sound-insulating aluminum alloy window also includes a composite soundproof window mechanism installed on the rear side wall of the aluminum alloy window frame. The composite soundproof window mechanism includes a frame-shaped window frame, and soundproof window sashes are respectively hinged to both ends of the frame-shaped window frame. The top and bottom of the frame-shaped window frame are respectively installed on the rear side wall of the aluminum alloy window frame via a track structure; The track structure includes a push-pull track fixedly connected to an aluminum alloy window frame. The top of the frame window frame is provided with long mounting openings. Several rollers are installed in the long mounting openings, and the rollers roll against the push-pull track. The aluminum alloy window frame is confined within the sliding track; When high noise occurs, the composite soundproof window mechanism is pushed to the back of the sliding window sash according to the direction of noise propagation, so as to adjust the sound insulation according to the location of the noise. After pushing the composite soundproof window mechanism to the designated position, the soundproof window sash is closed.

[0012] Preferably, the soundproof window sash includes a soundproof window frame hinged within a frame-shaped window frame, and a soundproof glass panel is fixedly connected inside the soundproof window frame; The soundproof window frames are locked and opened via a self-locking structure.

[0013] Preferably, the self-locking structure includes a spring lock installed on one side of the soundproof window frame, and a matching lock hole is provided on the other side of the soundproof window frame.

[0014] Preferably, the spring lock includes a lock post, and the soundproof window frame has a lock groove for sliding connection of the lock post. A spring is fixedly connected to the inner end of the lock post, and the spring is fixedly connected in the lock groove.

[0015] Preferably, a push handle is fixedly connected to the lock pin, and an opening communicating with the lock groove is provided on the soundproof window frame. The push handle passes through the opening, and the lock pin elastically extends or retracts into the lock groove during the pushing and pulling of the push handle.

[0016] Preferably, the composite soundproofed high-strength soundproof aluminum alloy window further includes a soundproof roll material mechanism installed on the composite soundproof window mechanism.

[0017] Preferably, the sound insulation roll material mechanism includes a roller mounted on one side of the sound insulation window frame, on which a flexible sound insulation roll material is wound. The soundproof window frame is fixedly connected to a bearing that rotatably connects to the roller.

[0018] Preferably, the flexible sound insulation roll is made of transparent rubber. After the flexible sound insulation roll is unwound, it changes from a rolled state to a horizontal state and is then placed on the sound insulation window frame.

[0019] Preferably, the free end of the flexible sound insulation roll is detachably positioned on the sound insulation window frame on the other side; Several noise reduction structures are fixedly connected to the flexible sound insulation roll; Preferably, the noise reduction structure includes a plurality of protruding vesicles, each vesicle having a vesicle cavity, and each vesicle including a curved contact portion that abuts against a glass plate, the curved contact portion having an integrally formed conical connecting portion, the curved contact portion and the conical connecting portion being integrally formed. The blister is made of elastic plastic.

[0020] The present invention has the following beneficial effects: 1. When high noise occurs, the composite soundproof window mechanism is pushed to the rear of the sliding window sash according to the direction of noise propagation, adjusting the sound insulation based on the noise's location. After pushing the composite soundproof window mechanism to the designated position, the soundproof window sash closes. If noise enters the room from the right, pushing the composite soundproof window mechanism to the right strengthens the sound insulation on the right side of the aluminum alloy window body. Since the noise passes through the aluminum alloy window sash, the composite soundproof window mechanism significantly reduces the amount of noise entering the room.

[0021] 2. In actual operation, when noise occurs, the composite soundproof window mechanism is adjusted to block the noise and reduce it sufficiently. At this point, the window sashes on the non-blocked areas of the aluminum alloy window body can be opened appropriately. This allows for ventilation when noise is present, while controlling the level of noise entering the room. This method greatly improves the flexibility of use.

[0022] 3. When the composite soundproof window mechanism is not needed, the soundproof window sash can be opened. At this time, the soundproof window sash completely exposes the aluminum alloy window body, thus not affecting the normal opening and closing of the window. At the same time, it does not affect the lighting.

[0023] 4. A soundproofing roll material mechanism is used, specifically employing a roller mounted on one side of the soundproof window frame, on which flexible soundproofing material is wound. The flexible soundproofing material is made of transparent rubber. It utilizes a thickened flexible rubber sheet, so that after the flexible soundproofing roll is unwound, it transitions from a rolled state to a horizontal state and rests on the soundproof window frame. This method further isolates noise.

[0024] 5. During the process of noise penetrating the glass plate, the vibration of the glass plate is the main cause of noise entering the room. Therefore, by using the bubble structure against the glass plate, energy is buffered. Specifically, the vibrating glass plate transmits vibrational energy to the bubbles. Because the bubbles are made of elastic material and have internal cavities, the noise energy is buffered during the repeated deformation of the bubbles. Furthermore, under the action of the high-density distribution of bubbles, the noise energy is significantly reduced. In actual testing, following this method, indoor noise is almost inaudible at night in quiet conditions. Therefore, for people sensitive to sound, such as those with sleep disorders, soundproofing using this method results in a very quiet indoor environment where outdoor noise is almost inaudible.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. 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. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0031] Example 1 like Figure 1-7As shown, a composite soundproof high-strength sound-insulating aluminum alloy window includes an aluminum alloy window body. The main structure of the aluminum alloy window body is the same as that of a conventional aluminum alloy sliding window disclosed in the prior art. The aluminum alloy window body includes an aluminum alloy window frame 1 (installed inside the window opening), and a sliding window sash 2 assembled and connected inside the aluminum alloy window frame 1. The window is opened and closed by pushing the sliding window sash 2.

[0032] In practical use, since noise often enters the room through aluminum alloy windows from a certain direction, it is necessary to improve the aluminum alloy windows to adjust and block noise according to the direction of noise entry.

[0033] Specifically, the composite soundproof high-strength soundproof aluminum alloy window also includes a composite soundproof window mechanism 3 installed on the rear side wall of the aluminum alloy window frame 1. The composite soundproof window mechanism 3 includes a frame-shaped window frame 31, and soundproof window sashes 33 are respectively hinged at both ends of the frame-shaped window frame 31 (specifically, the soundproof window sashes 33 include a soundproof window frame hinged in the frame-shaped window frame, and a soundproof glass plate is fixedly connected in the soundproof window frame).

[0034] The top and bottom of the aforementioned frame window frame 31 are respectively installed on the rear side wall of the aluminum alloy window frame 1 via a track structure.

[0035] Specifically, the track structure includes a push-pull track 11 fixedly connected to the aluminum alloy window frame 1 (the push-pull track 11 is L-shaped, that is, it includes a horizontal part that rolls the rollers and an integrally formed partition part, which is placed on the outer wall of the frame window frame 31 to prevent it from falling off).

[0036] Correspondingly, the top and bottom of the frame window frame 31 are respectively provided with long installation openings 311, and a number of rollers 32 are installed in the long installation openings. The rollers 32 roll against the push-pull rail 11; the aluminum alloy window frame 1 is limited in the push-pull rail 11. When high noise occurs, the composite soundproof window mechanism 3 is pushed to the rear of the sliding window sash according to the direction of noise propagation, thus adjusting the sound insulation based on the noise's location. After pushing the composite soundproof window mechanism 3 to the designated position, the soundproof window sash 33 is closed. If the noise enters the room from the right, the composite soundproof window mechanism 3 is pushed to the right, reinforcing the sound insulation on the right side of the aluminum alloy window body. At this point, because the noise passes through the window sash of the aluminum alloy window body, the amount of noise entering the room is greatly reduced due to the insulation provided by the composite soundproof window mechanism 3.

[0037] Through the above design, in actual operation, when noise occurs, the composite soundproof window mechanism 3 is adjusted to block the noise, and after the noise is sufficiently reduced, the window sashes on the non-blocked areas of the aluminum alloy window body can be opened appropriately. This allows for ventilation when noise is present, while controlling the level of noise entering the room. This method greatly improves the flexibility of use.

[0038] When the composite soundproof window mechanism 3 is not needed, the soundproof window sash 33 is opened. At this time, the soundproof window sash 33 completely exposes the aluminum alloy window body, thus not affecting the normal opening and closing of the window. At the same time, it does not affect the lighting.

[0039] Example 2 like Figure 1-7 As shown, based on the structure of Example 1, the above-mentioned composite soundproofed high-strength soundproof aluminum alloy window also includes a soundproof roll material mechanism installed on the composite soundproof window mechanism 3. The soundproof roll material mechanism further enhances noise insulation; for example, in quiet environments at night, noise is particularly noticeable, and the soundproof roll material mechanism further blocks noise.

[0040] Specifically, the soundproofing roll material mechanism includes a roller 41 installed on one side of the soundproof window frame (correspondingly, a shaft seat rotatably connected to the roller 41 is fixedly connected to the soundproof window frame). A flexible soundproofing roll 4 is wound on the roller 41; the flexible soundproofing roll 4 is made of transparent rubber. It uses a thickened flexible rubber sheet. Under normal circumstances, it is in a wound state. During use, pulling the free end of the flexible soundproofing roll 4 straightens it, and the free end is positioned on the other side of the soundproof window frame (specifically, a magnetic strip is fixedly connected to the free end of the flexible soundproofing roll 4, and a corresponding iron strip is fixed to the soundproof window frame; the magnetic attraction principle is used for positioning and easy opening). At this time, after unwinding the flexible soundproofing roll 4, it changes from a wound state to a horizontal state and blocks noise on the soundproof window frame. This method further isolates noise.

[0041] Example 3 like Figure 1-7 As shown, this embodiment, based on the structure of embodiment 2, uses a self-locking structure to lock and open the aforementioned soundproof window frames. Specifically, the self-locking structure includes a spring lock installed on the right-side soundproof window frame, and correspondingly, a matching lock hole is provided on the left-side soundproof window frame.

[0042] The spring lock includes a locking pin 51. A locking groove A is provided on the soundproof window frame, through which the locking pin 51 is slidably connected. A spring 52 is fixedly connected to the inner end of the locking pin 51, and the spring 52 is fixedly connected within the locking groove A. A push handle 511 is fixedly connected to the locking pin 51. An opening communicating with the locking groove A is provided on the soundproof window frame. The push handle passes through the opening. During the pushing and pulling of the push handle, the locking pin 51 elastically extends or retracts into the locking groove A.

[0043] Specifically, when the soundproof window frame is closed, the left and right soundproof window frames are combined. At this time, the locking pin 51 is locked into the lock hole. During the opening process, the operating push handle 511 is pushed inward until the locking pin 51 retracts into the lock groove A, thereby opening the window.

[0044] Example 4 like Figure 1-9 As shown, in order to significantly improve the noise reduction effect, multiple blister packs are welded (specifically, heated) onto the flexible sound insulation roll 4 based on the structure of Example 3. The distribution density of the blister packs is 3 blister packs welded per square centimeter.

[0045] The working principle of the noise reduction structure is as follows: when the flexible sound insulation roll 4 is opened, the flexible sound insulation roll 4 is pressed against the glass plate installed on the sound insulation window frame, and the bubble is kept in contact with the glass plate.

[0046] During the process of noise penetrating the glass plate, the vibration of the glass plate is the main cause of noise entering the room. Therefore, by using the bubble structure that contacts the glass plate, energy is buffered. Specifically, the vibrating glass plate transmits vibrational energy to the bubble 6. Since the bubble 6 is an elastic material and has cavities inside, the noise energy is buffered during the repeated deformation of the bubble 6. Thus, under the action of the high-density distribution of the bubble 6, the noise energy is significantly reduced. In actual testing, following the above method, indoor noise is almost inaudible at night in a quiet state. Therefore, for people who are sensitive to sound, such as those with sleep disorders, the indoor environment is very quiet after soundproofing using this method, and outdoor noise is almost inaudible.

[0047] Specifically, the noise reduction structure includes several protruding sacs 6, each sac 6 having a sac 6 cavity, each sac 6 including a curved contact portion 61 that abuts against a glass plate, the curved contact portion 61 having an integrally formed conical connecting portion 62, the curved contact portion 61 and the conical connecting portion being integrally formed; the sac 6 is made of elastic plastic material.

[0048] The curved structure design enables the vesicle 6 to effectively buffer noise through its elastic deformation during vibration deformation.

[0049] To improve the contact between the flexible sound insulation roll 4 and the glass plate, a magnetic strip 42 is installed on the side of the flexible sound insulation roll 4 facing the glass plate, and a thin iron strip is attached to the glass plate at the corresponding position. This allows the bubble 6 to be firmly attached using magnetic attraction, ensuring sufficient contact.

[0050] Example 5 Test Experiment The composite soundproof high-strength soundproof aluminum alloy window disclosed in this invention was used as the experimental group, and a conventional aluminum alloy sliding window on the market was used as the control group. The difference between the experimental group and the control group is that the control group did not have the composite soundproof window mechanism 3 installed.

[0051] Under the same test conditions, the noise-blocking effect of the two windows was tested separately.

[0052] like Figure 10 As shown, the test method is as follows: A noise source with continuously changing decibel levels (simulating various outdoor noises under normal conditions) is placed on the outside of the window, near the right side of the window. The composite soundproof window mechanism 3 of the experimental group is slowly pushed and pulled towards the right side of the window. The coverage rate of the composite soundproof window mechanism 3 covering the right side of the window is calculated as: Covered area / Uncovered area on the right side of the window X 100%. A decibel meter 7 for measuring noise level is placed on the inside of the window, specifically at the vertical line of the window's center line. The change in noise level is calculated as the area covering the right side of the window gradually increases during the pushing and pulling process, and a noise change graph is plotted.

[0053] like Figure 11 As shown, as the composite soundproof window mechanism 3 continuously covers an increased area on the right side of the window, the noise gradually decreases. The curve reaches its inflection point when the coverage area reaches 50%. When the coverage area exceeds 50%, the noise isolation effect increases dramatically. With 90% coverage, the noise level drops below 25dB and continues to decline. In contrast, the noise level remains consistently around 80dB. Therefore, for noise-sensitive individuals, high-intensity noise makes it impossible to fall asleep at night.

[0054] Obviously, when the device disclosed in this invention is combined with the sound insulation protection of the flexible sound insulation roll 4, the indoor noise level is very low.

[0055] 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.
