Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a sound-insulating and noise-reducing aluminum alloy window. Background Technology

[0002] Aluminum alloy is the most commonly used material in home furnishings since the industrial age, and its most common application is in various frames, especially door and window frames.

[0003] As cities expand, more and more new construction sites are starting near residential areas. Construction sites generally generate a lot of noise. Although current regulations require construction sites to manage the noise themselves, different groups of people have different tolerance levels for noise. Therefore, even after the noise is managed, it will still affect some residents in the surrounding area to a certain extent. Most residents will choose to close their doors and windows during construction hours to further reduce noise and ensure their normal lives. However, in practice, the results are often unsatisfactory. Utility Model Content

[0004] In order to solve the above problems, this utility model provides a soundproof and noise-reducing aluminum alloy window.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a soundproof and noise-reducing aluminum alloy window, including a window frame and a window sash, wherein soundproof glass is fixedly connected inside the window sash, a resonant cavity is provided inside the window frame, and partition strips are provided on both sides of the inner wall of the resonant cavity to divide the resonant cavity into multiple partition spaces. The relative angle between each partition strip is randomly set and adjacent partition spaces are interconnected. A groove is provided on the side of the window frame, and a protruding edge is provided on the side of the window sash for cooperating with the groove. A fixing mechanism is provided on the protruding edge.

[0006] By adopting the above solution, the resonant cavities set around the windows absorb and dissipate noise, thereby reducing the noise intensity passing through the windows and achieving a noise reduction effect. The partition strips further obstruct the propagation of sound waves within the resonant cavities and lengthen their propagation path, thereby increasing the loss of sound energy during propagation and reducing the noise intensity passing through the windows, thus enhancing the noise reduction capability.

[0007] Furthermore, a sound insulation strip is provided on the side of the window sash, and a soft pad is provided on the inner edge of the window frame. When the window sash is closed, the sound insulation strip comes into contact with the soft pad.

[0008] By adopting the above solution, noise transmitted through gaps can be effectively reduced by using a fluffy structure, which creates numerous cavities within the gaps. The fluff also vibrates after absorbing noise, thus dissipating the sound energy and achieving a good sound insulation and noise reduction effect.

[0009] Furthermore, each of the partition spaces in the resonant cavity located at the bottom of the window frame is filled with resonant particles.

[0010] Furthermore, the diameter of the resonant particles is less than 0.1 mm, and the total volume of the resonant particles is less than 1 / 5 of the total volume of the partition space.

[0011] By adopting the above scheme, the sound waves will cause the resonant particles to vibrate after entering the resonant cavity, thereby further consuming the sound energy and enhancing the noise reduction capability. When the noise is loud enough, the sound energy in the resonant cavity will cause the resonant particles to vibrate at a large amplitude, thus producing sound. At this time, the white noise generated by the small particles can be used to cover the external noise to a certain extent, thereby reducing the impact of noise on people.

[0012] Furthermore, the cross-section of the resonant cavity is irregular.

[0013] By adopting the above scheme, the irregularly shaped resonant cavity can more effectively impede the propagation of sound and increase the number of times the sound wave bounces off the wall, thereby increasing the loss of sound energy.

[0014] Furthermore, the window frame has mounting grooves at its four corners, and sound-insulating sponge pads are fixed in the mounting grooves. The sound-insulating sponge pads are used to contact the four corners of the window sash, and the surface of the sound-insulating sponge pads protrudes from the surface of the window frame.

[0015] By adopting the above solutions, sound-insulating foam pads can provide further protection for the four corners of windows. Utilizing their internal sponge-like porous structure, they achieve good sound insulation and prevent gaps from appearing at the corner joints due to prolonged use, thus ensuring that the windows' sound insulation and noise reduction capabilities are more durable.

[0016] Furthermore: the fixing mechanism includes a slot formed in the recess, a slot connected to the slot is provided on the window frame, a pin is slidably connected in the slot, a block is provided on the protruding edge for engaging with the slot and allowing the pin to pass through it, and a return spring is provided between the pin and the slot.

[0017] By adopting the above solution, the fixing mechanism can not only keep the doors and windows closed, but also make the convex edge fit fully against the side wall of the window frame, thereby reducing the gap width and enhancing the sound insulation of the window.

[0018] In summary, this utility model has the following beneficial effects:

[0019] By setting up a resonant cavity, when sound enters the cavity, the randomly angled partitions and irregularly shaped cross-sections increase the number of times the sound waves bounce off the walls. This gradually weakens and dissipates the sound energy of the noise during the bounce process. At the same time, due to the presence of resonant particles, when the noise is loud enough, the sound energy can drive the resonant particles to vibrate, thereby further absorbing the energy. The sound generated by the vibration of the resonant particles themselves is white noise, which is less harmful to the human body and can be used to counteract external noise, thus offsetting some of the adverse effects of noise. For the gaps in doors and windows, soft pads form a pile, creating a cavity structure in the gaps. The pile itself vibrates, further absorbing sound energy, thereby achieving the effect of sound insulation and noise reduction. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, a soundproof and noise-reducing aluminum alloy window includes a window frame 1 and a window sash 2. Soundproof glass 3 is fixedly connected inside the window sash 2. A resonant cavity 11 is provided inside the window frame 1. Sound waves transmitted to the resonant cavity 11 can resonate there, thus dissipating energy in advance and reducing the intensity of noise passing through the window frame 1, achieving a vibration reduction effect. The cross-section of the resonant cavity 11 is irregular. To reduce processing difficulty, a shape derived from a trapezoid can be used as the cross-section. The simplest shape can be achieved by overlapping the bases of two trapezoids. Due to the uneven boundary of the irregular cross-section, sound waves need to consume more energy to adjust after rebounding from the inner wall, thus accelerating sound energy loss and reducing noise. Partition strips 12 are provided on both inner walls of the resonant cavity 11, dividing the resonant cavity 11 into multiple partition spaces. The relative angle between each partition strip 12 is randomly set, and adjacent partition spaces are interconnected. The partition strips 12 extend the propagation path of the sound waves, thereby increasing energy loss during propagation and further reducing noise. The sound weakens, and the random angle also increases the uncertainty in the propagation process, so that the sound wave needs to consume more energy to adjust, further enhancing the noise reduction capability of the resonant cavity 11. When the sound passes through the resonant cavity 11 and exits the window frame 1, its intensity is basically no longer able to have a significant impact on the human body. Each partition space of the resonant cavity 11 located at the bottom of the window frame 1 is filled with resonant particles 15. The diameter of the resonant particles 15 is less than 0.1 mm, and the total volume of the resonant particles 15 is less than 1 / 5 of the total volume of the partition space. When the external noise is too strong and the resonant cavity 11 itself is not enough to reduce it to a harmless range, the excess sound energy will drive the resonant particles 15 to vibrate. The resonant particles 15 here can be foam particles. The vibration of the resonant particles 15 will generate friction between them, and friction will generate a certain amount of heat, thereby converting sound energy into kinetic energy and thermal energy, which will enhance the noise reduction capability. In addition, because the foam particles are lightweight, there will be large gaps when they are stacked together, forming a porous structure, thus having a stronger noise reduction capability.

[0030] like Figure 2 and Figure 6 As shown, a sound insulation strip 22 is provided on the side of the window sash 2, and a soft pad 14 is provided on the inner edge of the window frame 1. When the window sash 2 is closed, the sound insulation strip 22 contacts the soft pad 14. The sound insulation strip 22 can directly seal the gap between the window sash 2 and the window frame 1 as much as possible, thereby reducing the possibility and intensity of noise transmission from the gap. The soft pad 14 can form several new cavities between the window sash 2 and the window frame 1 using the pile. The pile itself vibrates with the sound waves and can also absorb sound energy, thereby further reducing the noise intensity passing through the window. In conjunction with the resonant cavity 11, a stronger sound insulation and noise reduction effect can be achieved.

[0031] like Figure 1 and Figure 3 As shown, mounting grooves 16 are provided at the four corners of the window frame 1, and sound-insulating sponge pads 5 are fixed in the mounting grooves 16. The sound-insulating sponge pads 5 are used to contact the four corners of the window sash 2. The surface of the sound-insulating sponge pads 5 protrudes from the surface of the window frame 1. In the prior art, the four corners of the window frame 1 are generally sealed and fixed with glue or rubber strips. As the usage time increases, the glue and rubber strips will gradually age, thereby losing their sealing ability and creating gaps. At this time, sound can be transmitted through the gaps. The sound-insulating sponge pads 5 are set on the inside of the four corners, and with their own sponge-like porous structure, they play a good role in absorbing sound, so that even if gaps are formed at the four corners of the window frame 1, there will be no sound leakage. This ensures that the window has a more durable sound insulation and noise reduction capability. Moreover, since the sound-insulating sponge pads 5 protrude from the surface of the window frame 1, they can be further pressed and compacted when the window is closed, thereby squeezing some of them into the gaps and filling them, further ensuring the sound insulation capability.

[0032] like Figure 2 and Figure 6 As shown, a groove 13 is provided on the side of the window frame 1, and a protruding edge 21 is provided on the side of the window sash 2 to cooperate with the groove 13. A fixing mechanism 4 is provided on the protruding edge 21. The fixing mechanism 4 can keep the window closed and minimize the gap between the window frame 1 and the window sash 2, thereby increasing the loss of sound when passing through the window and ensuring the sound insulation and noise reduction capability of the window. The fixing mechanism 4 includes a slot 41 opened in the groove 13, a latch 42 opened on the window frame 1 to communicate with the slot 41, a pin 43 slidably connected in the latch 42, a locking block 44 on the protruding edge 21 to mate with the slot 41 and allow the pin 43 to pass through it, and a return spring 45 is provided between the pin 43 and the latch 42. This setting is not only a locking structure for the closed state of the window itself, but also a structure to strengthen the sound insulation capability at the gap.

Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
