Technical Field

[0001] The utility model relates to the field of aluminum composite panels, in particular to a sound-absorbing decorative aluminum composite panel. Background Art

[0002] In order to reduce the outward transmission of sound, some buildings have high requirements for the sound absorption of walls and need to install interior panels with sound absorption effects.

[0003] Ordinary aluminum composite panels do not have sound absorption effects or have poor sound absorption. In order to improve the sound absorption effect of aluminum composite panels, a layer of foamed plastic can be filled in the aluminum composite panels, but the structural stability is poor, not resistant to compression, and the sound absorption effect is also difficult to meet higher requirements. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sound-absorbing decorative aluminum composite panel, while having a sound absorption effect and ensuring structural stability.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A sound-absorbing decorative aluminum composite panel, comprising: a back plate, a sound-absorbing layer, a front panel and a decorative layer. The sound-absorbing layer is arranged on the front surface of the back plate, the front panel is arranged on the front surface of the sound-absorbing layer, the decorative layer is arranged on the front surface of the front panel. A plurality of through holes communicating the back plate and the front panel are arranged in the sound-absorbing layer in an array. A non-woven fabric sleeve is arranged in the through hole. A first stepped column extending into the non-woven fabric sleeve is arranged in the back plate. A second stepped column extending into the non-woven fabric sleeve and abutting against the first stepped column is arranged in the front panel. A blind hole is arranged at the end of the first stepped column. A card slot communicating with the blind hole is arranged on the side surface of the first stepped column. Elastic pieces extending into the blind hole are symmetrically arranged at the end of the second stepped column. A wedge block entering the card slot is arranged at the end of the elastic piece. A sound-absorbing hole is concentrically arranged in the second stepped column.

[0007] Wherein, a first stepped hole corresponding to the first stepped column is arranged in the back plate.

[0008] Wherein, a second stepped hole corresponding to the second stepped column is arranged in the front panel.

[0009] Wherein, the sound-absorbing layer is made of a foamed plastic board.

[0010] Wherein, the decorative layer is made of felt or mesh cloth.

[0011] Wherein, a layer of adhesive is arranged on the back surface of the decorative layer.

[0012] Wherein, the back plate and the front panel are respectively made of aluminum plates.

[0013] Advantages of the present utility model: A sound-absorbing decorative aluminum composite panel can, through the cooperation of the first stepped column and the second stepped column, achieve support in the thickness direction of the aluminum composite panel and locking of the back panel and the front panel, improve the compressive performance and structural stability, and use sound-absorbing holes to divide noise and introduce it into the non-woven fabric sleeve for preliminary sound absorption and noise reduction. Then, the micropores on the non-woven fabric sleeve are used to transmit the noise to the sound-absorbing layer for further sound absorption and noise reduction, greatly improving the sound absorption and noise reduction effect.

[0020]

[0021] In the sound-absorbing layer 3, several through holes 12 communicating the back panel 1 and the front panel 2 are arranged in an array. A non-woven fabric sleeve 8 is arranged in the through holes 12. The non-woven fabric sleeve 8 contains a large number of tiny holes. Sound waves can penetrate deep into the interior of the non-woven fabric sleeve 8 along these tiny holes, and friction occurs with the fiber material inside the non-woven fabric sleeve 8 to convert sound energy into heat energy for sound absorption and noise reduction.

[0021] To improve the structural stability, a first stepped column 6 extending into the non-woven fabric sleeve 8 is arranged in the back panel 1. In this embodiment, a first stepped hole 11 corresponding to the first stepped column 6 is arranged in the back panel 1. The first stepped holes 11 are arranged in a rectangular array in the back panel 1 and are evenly distributed.

[0022] A second stepped column 7 extending into the non-woven fabric sleeve 8 and abutted against the first stepped column 6 is provided in the panel 2. A second stepped hole 10 corresponding to the second stepped column 7 is provided in the panel 2, which is convenient for assembly. Through the cooperation of the first stepped column 7 and the second stepped column 10, the support in the thickness direction of the aluminum composite panel can be realized, and the compressive effect is good. The first stepped column 6 and the second stepped column 7 are respectively made of plastic structures, and the cost of injection molding production is low.

[0023] In order to achieve self-locking after assembly, a blind hole 16 is provided at the end of the first stepped column 6, a card slot 14 communicating with the blind hole 16 is provided on the side of the first stepped column 6, elastic pieces 15 extending into the blind hole are symmetrically provided at the end of the second stepped column 7, and a wedge block 13 entering the card slot 14 is provided at the end of the elastic piece. It is convenient for assembly and realizes the self-locking of the first stepped column 6 and the second stepped column 7, improving the stability of the composite structure of the back plate 1, the sound-absorbing layer 3 and the panel 2.

[0024] A sound-absorbing hole 9 is concentrically provided in the second stepped column 7. The noise coming from the front is divided by the sound-absorbing hole 9 and then introduced into the non-woven fabric sleeve 8 for preliminary sound absorption and noise reduction. Then, the noise is divided again by the micropores on the non-woven fabric sleeve 8 and transmitted to the sound-absorbing layer 3 for further sound absorption and noise reduction, greatly improving the overall sound absorption and noise reduction effect.

[0025] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
