Description

Technical Field

[0001] This utility model relates to the field of soundproof cabin technology, specifically a lightweight soundproof cabin. Background Technology

[0002] A soundproof cabin is a closed or semi-closed space constructed with special designs and materials, designed to effectively isolate external noise and reduce internal sound leakage, providing users with a low-noise environment. Its applications are wide-ranging, covering fields such as offices, recording studios, medical facilities, aviation, and industry.

[0003] For example, an existing Chinese patent (CN221568008U) discloses a quiet cabin for private offices, including a cabin body. A door mechanism is provided on the front surface of the cabin body. A night light is installed on the inner wall of the top of the cabin body. A desktop is provided below the night light. One end of the desktop is connected to an upward-flipping folding mechanism. A support plate is movably connected to the lower surface of the end of the desktop away from the upward-flipping folding mechanism. A charging mechanism is provided on the inner side of the desktop.

[0004] To ensure structural strength and sound insulation performance, traditional soundproof cabins often employ a composite structure design of "double-layer steel plates sandwiched with sound-insulating cotton". While this construction method, with high-density materials at its core, can effectively block noise, the large thickness of the steel plates and the large amount of sound-insulating cotton filling result in a significant increase in the cabin's weight, which in turn limits its mobility, ease of installation, and adaptability to lightweight scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight, quiet cabin to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight soundproof cabin, comprising: four arc-shaped aluminum alloy profiles, vertical sound insulation panels, and horizontal sound insulation panels. Each of the four arc-shaped aluminum alloy profiles has a horizontal bar and a vertical bar at both ends. The four aluminum alloy profiles, the horizontal bars, and the vertical bars form a rectangular frame. A sealed door is provided on one side of the rectangular frame. Horizontal sound insulation panels are provided at the top and bottom of the rectangular frame. Vertical sound insulation panels are provided around the perimeter of the rectangular frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-5This utility model provides a technical solution: a lightweight soundproof cabin, comprising: an arc-shaped aluminum alloy profile 1, a vertical sound insulation panel 6, and a horizontal sound insulation panel 7. There are four arc-shaped aluminum alloy profiles 1, and each end of the four arc-shaped aluminum alloy profiles 1 is provided with a horizontal bar 3 and a vertical bar 4. The four aluminum alloy profiles 1, the horizontal bar 3, and the vertical bar 4 form a rectangular frame. The rectangular frame is composed of four arc-shaped aluminum alloy profiles 1, the horizontal bar 3, and the vertical bar 4. The aluminum alloy profiles are lightweight. Compared with traditional materials such as steel, the overall weight is greatly reduced while ensuring the structural strength of the frame, realizing a lightweight design and facilitating the movement and installation of the soundproof cabin.

[0020] A sealed door 5 is located on one side of the rectangular frame. This door facilitates personnel entry and exit from the soundproof chamber, while its excellent sealing effectively prevents sound leakage from the door gaps, enhancing the sound insulation of the chamber without compromising its overall lightweight characteristics, as the sealed door 5 can be made of suitable materials to meet lightweight requirements. Horizontal sound insulation panels 7 are located at the top and bottom of the rectangular frame, and vertical sound insulation panels 6 are located around the perimeter of the frame. Together, these panels form a closed soundproof space, blocking sound transmission from all directions and improving the sound insulation performance of the soundproof chamber. This layout makes efficient use of space, ensuring sound insulation without significantly increasing weight due to excessive structural additions, thus adhering to the lightweight design philosophy.

[0021] The vertical sound insulation panel 6 is composed of sound-absorbing cotton 602, aluminum honeycomb sandwich panel 603, and fiberglass board 604 arranged sequentially from the inside to the outside. The sound-absorbing cotton 602, aluminum honeycomb sandwich panel 603, and fiberglass board 604 are closely arranged, and through the effect of different materials on sound waves of different frequencies, comprehensive absorption and blocking of sound is achieved. Moreover, each layer of material is relatively light, which improves the sound insulation effect without making the vertical sound insulation panel 6 too heavy, thus contributing to the overall lightweight design.

[0022] The vertical sound insulation panel 6 is wrapped with a plastic shell 601. The plastic shell 601 is fixed to the sound-absorbing cotton 602 by adhesive, and the plastic shell 601 is also fixed to the fiberglass board 604 by adhesive. The sound-absorbing cotton 602, aluminum honeycomb sandwich panel 603, and fiberglass board 604 are also fixed by adhesive. The plastic shell 601 protects the internal materials from damage caused by the external environment. The adhesive fixing method provides a strong connection without adding excessive weight. Compared with other complex connection structures, it ensures the stability between the materials and meets the requirements of lightweight design.

[0023] The vertical sound insulation panel 6 has the same structure as the horizontal sound insulation panel 7. A ventilation fan 8 is installed on the top horizontal sound insulation panel 7. This identical structural design facilitates mass production and reduces production costs. At the same time, the unified materials and structure reduce design complexity while ensuring consistent sound insulation performance, which helps control overall weight and achieve the goal of lightweight design.

[0024] A rectangular strip 605 is provided on one side of the vertical sound insulation panel 6, and a rectangular groove that mates with the rectangular strip 605 is provided on one side of the adjacent vertical sound insulation panel 6. The mating structure of the rectangular strip 605 and the rectangular groove ensures a tight connection between adjacent vertical sound insulation panels 6, enhances the stability of the overall structure, and prevents sound leakage from the panel seams. This connection method is simple and reliable, requires no additional connectors, does not add excessive weight, and helps maintain lightweight characteristics.

[0025] The inner walls at both ends of the curved aluminum alloy profile 1 are provided with first end positioning grooves 101, and the inner walls at both ends of the curved aluminum alloy profile 1 are provided with second end positioning grooves 102 above the first end positioning grooves 101. A fan-shaped positioning groove 103 is provided on the inner wall of the curved corner of the curved aluminum alloy profile 1. These positioning grooves provide precise positioning for the installation of the curved cover 2, ensuring accurate connection between the curved cover 2 and the curved aluminum alloy profile 1, and improving the stability and sealing of the overall structure. The design of the positioning grooves is simple and reasonable; while fulfilling the positioning function, it does not significantly affect the strength and weight of the aluminum alloy profile, conforming to lightweight design principles.

[0026] A circumferential positioning plate 205 is provided around one side of the arc-shaped cover 2. The circumferential positioning plate 205 can be locked onto the outer side of the end of the arc-shaped aluminum alloy profile 1. End positioning strips 201 are provided on the inner walls of both ends of the arc-shaped cover 2. End positioning plates 202 are provided on the inner walls of both ends of the arc-shaped cover 2 above the end positioning strips 201. Arc-shaped positioning plates 203 are provided on the inner walls of the arc-shaped corners of the arc-shaped cover 2. An oblique positioning plate 204 is provided on one side of the inner side of the arc-shaped corners of the arc-shaped cover 2. The circumferential positioning plate 205, end positioning strips 201, end positioning plates 202, arc-shaped positioning plates 203, and oblique positioning plates 204 work together to precisely fit with the positioning grooves on the arc-shaped aluminum alloy profile 1, achieving a stable connection between the arc-shaped cover 2 and the arc-shaped aluminum alloy profile 1. This multi-positioning structure ensures the tightness and stability of the connection, prevents sound leakage, and the reasonable design of these positioning components does not add too much weight, contributing to the overall lightweight design. The outer contour of the end positioning strip 201 fits against the inner wall of the first end positioning groove 101, the outer contour of the end positioning strip 201 fits against the inner wall of the second end positioning groove 102, the arc-shaped positioning plate 203 fits against the arc-shaped inner wall of the fan-shaped positioning groove 103, and the inclined positioning plate 204 fits against the inclined inner wall of the fan-shaped positioning groove 103. This tight fit further enhances the connection stability and sealing between the arc-shaped cover 2 and the arc-shaped aluminum alloy profile 1, effectively preventing sound transmission. At the same time, this fit design does not require additional sealing materials or complex connection structures, ensuring sound insulation without adding excessive weight, thus meeting lightweight requirements.

[0027] Sound-absorbing cotton 602, positioned close to the interior of the soundproof cabin, absorbs mid-to-high frequency sound waves, reducing the impact of reflected sound on the cabin's sound field. Aluminum honeycomb sandwich panel 603 blocks the transmission of low-frequency sound waves, while fiberglass board 604 reflects high-frequency sound waves, reducing sound wave transmission. The sound-absorbing cotton 602, placed close to the interior, effectively absorbs mid-to-high frequency sound waves generated within the cabin, preventing multiple reflections and reverberation, thus improving the acoustic environment and enhancing the comfort of the soundproof cabin. Furthermore, the lightweight material of sound-absorbing cotton 602 does not significantly contribute to the overall weight. The unique honeycomb structure of aluminum honeycomb sandwich panel 603 provides excellent vibration and sound insulation performance, effectively blocking the transmission of low-frequency sound waves and enhancing the soundproof cabin's ability to block sounds of different frequencies. Simultaneously, the relatively lightweight aluminum honeycomb sandwich panel 603 contributes to weight reduction while improving sound insulation. 604 fiberglass board has a smooth surface and excellent reflectivity for high-frequency sound waves, reflecting most of them back and reducing sound wave transmission to the outside of the soundproof chamber, thus further improving sound insulation. Furthermore, 604 fiberglass board is lightweight, meeting lightweight design requirements.

[0028] The soundproof cabin utilizes an aluminum alloy frame, leveraging its lightweight and high strength to achieve a lightweight overall design. The multi-layered sound insulation panel structure rationally utilizes the sound insulation properties of different materials, ensuring effective soundproofing while controlling the weight of each layer. Compared to existing soundproof cabins, this design solves the problems of excessive weight and inconvenience in movement that may exist with traditional soundproof cabins. Through optimized material selection and structural design, the overall weight of the soundproof cabin is significantly reduced while achieving good sound insulation, making it easier to transport, install, and use. This also lowers production costs and enhances the product's market competitiveness.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
