[0003] In the prior art, the sound-absorbing laminated board usually consists of three layers: upper, middle, and lower. Among them, the middle sound-absorbing layer plays a key sound-absorbing role. With the passage of time, the existing sound-absorbing laminated board may be affected by factors such as dust and moisture due to the long-term exposure of the sound-absorbing layer to the air, resulting in a gradual decline in the sound-absorbing effect. When the sound-absorbing effect drops to a certain extent, in order to ensure good sound-absorbing performance, the whole board often needs to be replaced. This replacement method is not only troublesome to operate but also causes serious waste of resources.

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the following further describes the present invention with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1-5 shown, the present invention provides a sound-absorbing laminated board, including a top plate 1, an installation frame 2, and a back plate 3. First embedded grooves 11 are opened at positions near the four corners on the outer surface of the top plate 1. First clamping blocks 12 are fixedly connected between the inner surfaces of the multiple first embedded grooves 11. Installation grooves 21 are opened at positions near the four corners on the outer surface of the installation frame 2. Card sleeves 22 are fixedly connected between the inner surfaces of the multiple installation grooves 21. Second embedded grooves 31 are opened at positions near the four corners on the outer surface of the back plate 3. Second clamping blocks 32 are fixedly connected between the inner surfaces of the multiple second embedded grooves 31. The positions of the first embedded grooves 11, the second embedded grooves 31, and the installation grooves 21 correspond to each other. The first clamping block 12 is snap-fitted with the card sleeve 22. A sound-absorbing cotton 4 is fixedly connected between the inner surfaces of the installation frame 2 near the bottom.

[0024] The effect achieved by the entire Example 1 is that when using this device, the top plate 1, as the bottommost component, has first embedded grooves 11 opened at positions near the four corners on the outer surface. These first embedded grooves 11 not only enhance the strength of the top plate 1 but also serve as a key part of the fixing mechanism. A first clamping block 12 is fixed to the inner surface wall of each first embedded groove 11 through a metal connecting piece. These clamping blocks are made of metal material and are in a specific shape, facilitating subsequent quick connection. The installation frame 2, as the core support structure, has installation grooves 21 opened at corresponding positions on its outer surface. The design of the installation grooves 21 fully considers the cooperation with the top plate 1 and the clamping blocks to ensure that the two can be accurately docked. More importantly, a clamping sleeve 22 is fixed to the inner surface wall of the installation groove 21 through bolts. These clamping sleeves 22 are made of a metal material with wear resistance and good elasticity and can achieve a firm and flexible clamping connection with the first clamping blocks 12 of the top plate 1. The back plate 3, as the topmost component, also has second embedded grooves 31 opened at positions near the four corners and has second clamping blocks 32 made of metal material inside. The existence of the second embedded grooves 31 and the second clamping blocks 32 does not affect the clamping connection between the top plate 1 and the installation frame 2. They are independent of each other and jointly constitute the stable foundation of the entire structure. The first embedded grooves 11, the second embedded grooves 31, the first clamping blocks 12, the second clamping blocks 32, the installation grooves 21, and the clamping sleeves 22 are all made of metal material. Since the strength of the board itself is not very high, repeated disassembly and reassembly connections will affect the service life of the overall board. However, using metal connecting pieces for connection has higher strength and stiffness, which can ensure the stability and reliability of the connection, increase the service life of the entire board for repeated disassembly and reassembly. During the assembly process, the top plate 1 is placed below the installation frame 2, and the back plate 3 is placed above the installation frame 2, so that the first clamping blocks 12 and the second clamping blocks 32 can easily be inserted into the clamping sleeves 22 to achieve seamless clamping among the three. This connection method through metal connecting pieces not only simplifies the installation steps but also greatly improves the stability and durability of the structure. At the same time, due to the flexibility of the clamping mechanism, the disassembly process is also simple and fast, and it can be completed without complex tools or professional skills. This combined sound-absorbing structure realizes the quick assembly and disassembly among the top plate 1, the installation frame 2, and the back plate 3 through a clever clamping connection design of metal materials, which not only facilitates maintenance and replacement but also ensures the stability of the structure and the sound-absorbing effect. A sound-absorbing cotton 4 is fixed at a position near the bottom inside the installation frame 2. This is a porous material that can effectively absorb and weaken the incoming sound energy, reduce noise propagation, and improve the quietness of the overall environment. The entire design allows for the easy replacement of the damaged or aged middle sound-absorbing layer without affecting the upper and lower layer structures, effectively extending the service life of the overall board. This modular replacement method not only simplifies the operation process, reduces the maintenance cost, but also significantly reduces resource waste and promotes environmental protection and sustainable development.

[0025] Example 2: As Figures 1-5As shown in the figure, a first thin plate 41 is fixedly connected between the inner walls of the installation frame 2 near the upper part. A plurality of dampers 43 are fixedly connected to the top of the first thin plate 41. Springs 42 are sleeved on the outer surfaces of the plurality of dampers 43. A second thin plate 44 is fixedly connected between the tops of the plurality of dampers 43. The top of the second thin plate 44 is in close contact with the bottom of the back plate 3. The bottom of the spring 42 is fixedly connected to the top of the first thin plate 41, and the top of the spring 42 is fixedly connected to the bottom of the second thin plate 44. The top of the top plate 1 is fixedly connected to the bottom of the installation frame 2, and the top of the installation frame 2 is fixedly connected to the bottom of the back plate 3.

[0026] The overall effect achieved by the entire Embodiment 2 is that a shock absorption system is designed at a position near the top inside the installation frame 2, including a first thin plate 41, a plurality of dampers 43, springs 42, and a second thin plate 44. The first thin plate 41 is fixed inside the installation frame 2, and dampers 43 are installed on it. Springs 42 are sleeved outside each damper 43. The tops of all the dampers 43 are jointly connected to the second thin plate 44, and the second thin plate 44 is in close contact with the bottom of the back plate 3. When external forces act on the back plate 3, these forces are first transmitted to the second thin plate 44, and then buffered and dispersed through the combined action of the springs 42 and the dampers 43. The springs 42 provide initial elastic buffering and absorb part of the impact force, while the dampers 43 consume the remaining energy through the viscous medium inside them, further reducing the transmission of vibration. In this way, most of the vibration energy is effectively weakened before being transmitted to the installation frame 2 and the top plate 1, protecting the stability of the overall structure and extending the service life.

[0027] Working principle: When using this device, the top plate 1 serves as the bottommost component, the mounting frame 2 serves as the core support structure, and the back plate 3 serves as the topmost component, jointly constituting a solid foundation for the entire structure. The first embedded groove 11, the second embedded groove 31, the first clamping block 12, the second clamping block 32, the mounting groove 21, and the bushing 22 are all made of metal materials. Since the strength of the board itself is not very high, repeated disassembly and reassembly connections will affect the service life of the overall board. However, using metal connectors for connection has higher strength and stiffness, which can ensure the stability and reliability of the connection, increase the service life of the entire board for repeated disassembly and reassembly. During the assembly process, the top plate 1 is placed below the mounting frame 2, and the back plate 3 is placed above the mounting frame 2, enabling the first clamping block 12 and the second clamping block 32 to easily snap into the bushing 22, achieving seamless clamping among the three. This connection method using metal connectors not only simplifies the installation steps but also greatly improves the stability and durability of the structure. At the same time, due to the flexibility of the clamping mechanism, the disassembly process is also simple and fast, and can be completed without complex tools or professional skills. Through the ingenious clamping connection design of metal materials, this combined sound-absorbing structure realizes the rapid assembly and disassembly among the top plate 1, the mounting frame 2, and the back plate 3, which not only facilitates maintenance and replacement but also ensures the stability of the structure and the sound-absorbing effect. Inside the mounting frame 2, near the bottom, a sound-absorbing cotton 4 is fixed. This is a porous material that can effectively absorb and weaken the incoming sound energy, reduce noise transmission, and improve the quietness of the overall environment. The entire design allows for the easy replacement of the damaged or aged middle sound-absorbing layer without affecting the upper and lower layer structures, effectively extending the service life of the overall board. This modular replacement method not only simplifies the operation process, reduces the maintenance cost, but also significantly reduces resource waste, promoting environmental protection and sustainable development. Moreover, a shock-absorbing system is designed near the top inside the mounting frame 2, including a first thin plate 41, multiple dampers 43, springs 42, and a second thin plate 44. The first thin plate 41 is fixed inside the mounting frame 2, on which dampers 43 are installed. Each damper 43 is sleeved with a spring 42 outside. The tops of all dampers 43 are jointly connected to the second thin plate 44, and the second thin plate 44 is closely attached to the bottom of the back plate 3. When an external force acts on the back plate 3, these forces are first transmitted to the second thin plate 44, and then buffered and dispersed through the combined action of the springs 42 and the dampers  43. The springs 42 provide initial elastic buffering and absorb part of the impact force, while the dampers 43 consume the remaining energy through the viscous medium inside them, further reducing the transmission of vibration. In this way, most of the vibration energy is effectively weakened before being transmitted to the mounting frame 2 and the top plate 1, protecting the stability of the overall structure and extending its service life.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
