[0021] Please refer to Figures 1-4 A punched aluminum plate with a noise reduction interlayer, comprising a first plate body 1 and a second plate body 2, the edge profiles of the first plate body 1 and the second plate body 2 are matched, when the back surfaces of the first plate body 1 and the second plate body 2 are attached together, they can coincide with each other, the inner side of the back surface of the first plate body 1 is provided with a containing groove 3, the front surface of the first plate body 1 is provided with a hole 4, the hole 4 is formed by punching, and is communicated with the containing groove 3 of the back surface of the first plate body 1, the edges between the first plate body 1 and the second plate body 2 are provided with a fixing assembly, the first plate body 1 and the second plate body 2 attached together can be fixedly connected together through the fixing assembly, so as to facilitate the assembly of the first plate body 1 and the second plate body 2 during manufacturing, the first plate body 1 and the second plate body 2 are further provided with a sound-absorbing cotton sheet 5, which can be placed in the containing groove 3 of the back surface of the first plate body 1 and is matched in size with the containing groove 3, the noise generated on the front surface of the first plate body 1 can be conducted into the containing groove 3 through the hole 4, and the sound-absorbing cotton sheet 5 placed in the containing groove 3 can absorb the noise, the inside of the second plate body 2 is provided with a hollow sound insulation cavity 6, the vibration of air molecules in the hollow sound insulation cavity 6 is caused by sound waves, and then sound energy is converted into heat energy, further reducing the noise conducted to the wall through the second plate body 2, thereby playing a noise reduction role.

[0022] In use, the structure can be provided as a decorative panel on the wall in the room, so that the front of the first plate body 1 faces the room, and the noise generated in the room can be conducted through the holes 4 on the front of the first plate body 1 into the accommodation groove 3, so that the sound-absorbing cotton sheet 5 in the accommodation groove 3 can absorb the generated noise, avoiding the noise from being conducted to the wall in the room, so that the aluminum plate structure has good noise reduction and sound insulation effect. In addition, the hollow sound insulation cavity 6 can further reduce the noise conducted to the wall on the back of the second plate body 2 through the second plate body 2, so that the structure can effectively avoid the noise generated in the room from being conducted to the wall in the room and absorb the noise in the room, reducing the noise pollution in the room and outside.

[0023] Further, please refer to Figures 1-4 The fixing assembly includes screw grooves 7 provided at the four corners of the edge of the first plate body 1, mounting holes 8 provided at the four corners of the edge of the second plate body 2 and corresponding to the screw grooves 7, and fixing rings 9 provided inside the mounting holes 8. When the back of the first plate body 1 and the back of the second plate body 2 are attached to each other, the screw grooves 7 can be aligned and inserted into the inside of the mounting holes 8. At this time, the end of the screw groove 7 will abut against the fixing ring 9 inside the mounting hole 8. At this time, the screw can be inserted into the mounting hole 8 from the front of the second plate body 2 and rotated and screwed into the inside of the screw groove 7. When the end of the screw abuts against one side of the fixing ring 9, the fixing ring 9 inside the mounting hole 8 and the screw groove 7 are tightly attached together and cannot be separated, thereby achieving the fixed connection between the first plate body 1 and the second plate body 2. It is convenient to assemble the first plate body 1 and the second plate body 2. In addition, the first plate body 1 and the second plate body 2 can be disassembled by unscrewing the screw from the inside of the screw groove 7. At this time, the sound-absorbing cotton sheet 5 inside the accommodation groove 3 is exposed to the outside, so that the aging sound-absorbing cotton sheet 5 can be replaced. After the first plate body 1 and the second plate body 2 are fixedly connected, the end of the screw will be inserted into the inside of the mounting hole 8 and will not be exposed, so that the front of the second plate body 2 can also be kept flat. When the aluminum plate is assembled on the wall in the room, the front of the second plate body 2 can be flatly attached to the wall.

[0024] Further, please refer to Figures 1-4 The inside of the accommodation groove 3 is also provided with a protective film 10 between the inner wall of the accommodation groove 3 and the sound-absorbing cotton sheet 5. When dust or moisture in the air enters the inside of the accommodation groove 3 through the hole 4, the dust or moisture will be blocked by the protective film 10 and will not directly contact the sound-absorbing cotton sheet 5 inside the accommodation groove 3, thereby improving the dustproof and moisture-proof effect of the sound-absorbing cotton sheet 5 and ensuring the performance of the sound-absorbing cotton sheet 5.

[0025] Further, please refer to Figures 1-4The back edge of the first plate body 1 is provided with a damping strip 11, which can isolate the joint between the second plate body 2 and the back of the first plate body 1 when they are attached to each other. The damping strip 11 is made of rubber or polyurethane elastic material, which can absorb and reduce the transmission of vibration energy at the edge position of the first plate body 1 and the second plate body 2, thereby improving the sound insulation and noise reduction effect at the edge contact position of the first plate body 1 and the second plate body 2.

[0026] Further, please refer to Figures 1-4 The hollow sound insulation cavity 6 is internally provided with a plurality of groups of reinforcing ribs 12, which are distributed longitudinally and transversely in the hollow sound insulation cavity 6. The reinforcing ribs 12 in the hollow sound insulation cavity 6 form a grid-shaped fixing frame structure, which can effectively improve the strength of the aluminum plate body when the first plate body 1 and the second plate body 2 are connected together to form the aluminum plate body, and avoid bending deformation under the action of a large external force.

[0027] Further, please refer to Figures 1-4 The back of the second plate body 2 is provided with a protruding part 13, which is matched with the accommodating groove 3. When the back of the first plate body 1 and the second plate body 2 are attached to each other and fixedly connected together, the protruding part 13 can extend into the inside of the accommodating groove 3 to tightly press the sound-absorbing cotton sheet 5 in the accommodating groove 3, so that the sound-absorbing cotton sheet 5 can be tightly attached to the inner wall of the accommodating groove 3 to tightly block the hole 4, avoid the sound-absorbing cotton sheet 5 in the accommodating groove 3 to be loose and a large gap to be generated between the sound-absorbing cotton sheet 5 and the hole 4, and further ensure the noise reduction effect of the sound-absorbing cotton sheet 5.

[0028] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
