[0022] An aluminum plate 1 is fixedly connected to the upper and lower surfaces of the honeycomb core body 2. A storage groove 9 is provided on the side of the aluminum plate 1 close to the installation of the honeycomb core body 2. The storage groove 9 improves the tightness of the aluminum honeycomb core. A sound-absorbing cotton board 10 is fixedly connected inside the storage groove 9. The sound-absorbing cotton board 10 is in close contact with the surface of the honeycomb core body 2. A rubber pad 6 is provided between the honeycomb core body 2 and the sound-absorbing cotton board 10. The sound-absorbing cotton board 10 and the rubber pad 6 cooperate to improve the noise reduction ability of the aluminum honeycomb core.

[0023] A plurality of support strips 7 are fixedly connected to one side of the rubber pad 6 close to the sound-absorbing cotton board 10. The plurality of support strips 7 are cross-distributed in a square shape. The support strips 7 allow a certain space between the rubber pad 6 and the sound-absorbing cotton board 10 to form a sound-absorbing cavity. The sound-absorbing cavity is a common acoustic design technology used to reduce indoor noise and improve sound quality. The sound-absorbing cavity is usually composed of a space filled with sound-absorbing materials. Its working principle is to reduce the reflection and echo of sound by absorbing the energy of sound waves, thereby reducing the noise level and improving the clarity of sound, thereby further improving the noise reduction ability of the aluminum honeycomb core. The surface of the support strips 7 is provided with a plurality of exhaust holes 8. The exhaust holes 8 and the spaces between the plurality of support strips 7 are interconnected. The exhaust holes 8 prevent abnormal air pressure inside the aluminum honeycomb core.

[0024] The upper and lower ends of the honeycomb core body 2 are located inside the storage groove 9, and the left and right inner walls of the storage groove 9 are provided with docking slots 11. When the aluminum honeycomb core is produced, the docking side panel 3 is located inside the docking slot 11, and the docking side panel 3 cooperates with the docking slot 11 to improve the convenience of docking the aluminum honeycomb core. A baffle 12 is fixedly connected to one end of the docking slot 11 close to the honeycomb core body 2, and the baffle 12 is in close contact with a side of the pressure plate 4 close to the honeycomb core body 2. The baffle 12 improves the stability of the honeycomb core body 2 after docking with the aluminum plate 1.

[0025] Working principle: When docking the honeycomb core body 2 with the aluminum plate 1, first press the pressure plate 4 on the right, and dock the docking side plate 3 with the docking slot 11 by tilting the honeycomb core body 2. At this time, press the pressure plate 4 on the left and pull the honeycomb core body 2 to the left with all your strength to ensure that the docking side plate 3 at the left end is docked with the docking slot 11, and the pressure plate 4 that lacks pressure bounces up and resets. At this time, the pressure plate 4 is affected by the height of the docking slot 11 and cannot be fully bounced up. Affected by the pressure plate 4, the flat plate 5 is in close contact with the upper wall of the docking slot 11. The friction between the baffle 12 and the docking side plate 3 and the docking slot 11 ensures that the honeycomb core body 2 has sufficient stability after docking with the aluminum plate 1.
