[0002] Noise is a sound with chaotic high-pitched and intensity variations that sounds discordant. It is produced by irregular vibrations. Any sound that interferes with people's normal rest, study, and work is noise. The most direct harm of noise to the human body is hearing damage. It also affects the central nervous system, causing headaches, insomnia, memory loss, and other neurasthenia-related problems. Therefore, soundproof doors were developed. Soundproof doors are mainly used in places with high sound insulation requirements, primarily for soundproofing. Traditional soundproof doors mainly consist of a door panel and internal filling. However, gaps between the edges of the internal filling and the door panel can easily affect the soundproofing effect. Furthermore, soundproof doors with only one type of filling have relatively poor sound insulation performance.

[0003] Therefore, this application provides a soundproof door panel with composite filler, which aims to provide a soundproof door with good sound insulation effect. Utility Model Content

[0004] This utility model provides a soundproof door panel with composite filler, which aims to solve the problems pointed out in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A soundproof door panel with composite filler includes: a door panel, a door core filler, and a fixing frame;

[0007] The door core filler is located inside the door panel, and the fixing frame is located at the outer edge of the door core filler for fixing the door core filler. The outer edge of the fixing frame is adapted to the inner cavity edge of the door panel.

[0008] The door core filling includes honeycomb cardboard and sound-insulating foam board, which are stacked in the middle of the fixed frame.

[0009] Furthermore, a flange is provided in the middle of the inner sidewall of the fixing frame, which divides the internal area of ​​the fixing frame into an intermediate mounting layer and an outer mounting layer. The intermediate mounting layer is used to install the honeycomb cardboard, and the outer mounting layer is used to install the sound insulation foam board.

[0010] Furthermore, the upper and lower side walls of the fixing frame are provided with several clamps, and the clamps extend to the inner side of the fixing frame for fixing the sound insulation foam board.

[0011] The clamp is provided with a number of fastening screws, and the clamp is fixedly connected to the fixed frame by the fastening screws.

[0012] Furthermore, the outer diameter of the honeycomb holes on the honeycomb cardboard is 15mm, and the thickness of the paper wall forming the honeycomb holes is 3mm.

[0013] Furthermore, the overall thickness of the door core filling is 80mm, and the thickness of the honeycomb cardboard is 20mm.

[0014] Furthermore, the door panel includes: panels located on the front and rear sides of the door panel, sealing strips located on the upper and lower sides of the door panel, and a bent portion provided on one side of each panel, the bent portion cooperating with another panel to form the left and right sides of the door panel;

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0031] like Figure 1-4 As shown, a soundproof door panel with composite filler includes: door panel 1, door core filler 2, and fixing frame 3;

[0032] The door core filler 2 is located inside the door panel 1, and the fixing frame 3 is located on the outer edge of the door core filler 2 for fixing the door core filler 2. The outer edge of the fixing frame 3 is adapted to the inner cavity edge of the door panel 1.

[0033] The door core filling 2 includes: honeycomb cardboard 201 and sound insulation foam board 202, which are stacked in the middle of the fixed frame 3.

[0034] Honeycomb cardboard 201 and sound-insulating foam board 202 have different sound insulation principles, and their combination can form a more comprehensive sound insulation system. When sound waves enter the honeycomb cells, they are constantly reflected and refracted on the cell walls, consuming sound energy; while the sound-insulating foam board has a large number of tiny pores inside, sound waves can also consume sound energy when they propagate in the pores, thus achieving sound insulation. The layered arrangement of the two can better block and absorb sound waves of different frequencies, significantly improving the overall sound insulation effect of the door panel.

[0035] The fixed frame 3 ensures the stability of the door core filling 2, preventing the honeycomb cardboard 201 and sound insulation foam board 202 from shifting or deforming during installation and use, ensuring that they are always tightly fitted, reducing sound leakage caused by gaps between materials, further improving sound insulation performance, and effectively preventing gaps between the door core filling 2 and the door panel 1 structure from affecting the sound insulation effect of the soundproof door.

[0036] like Figure 4 As shown, a flange 303 is provided in the middle of the inner sidewall of the fixing frame 3. The flange 303 divides the inner area of ​​the fixing frame 3 into an intermediate mounting layer and an outer mounting layer. The intermediate mounting layer is used to install the honeycomb cardboard 201, and the outer mounting layer is used to install the sound insulation foam board 202.

[0037] Different sound insulation materials have their own optimal working conditions and acoustic characteristics. Separating the honeycomb cardboard 201 and sound insulation foam board 202 for installation via flange 303 avoids issues such as mutual compression or excessive tightness affecting their respective acoustic performance, ensuring they can independently and fully perform their sound insulation function. During production, dividing the internal area of ​​the fixing frame 3 into different installation layers makes the installation of honeycomb cardboard 201 and sound insulation foam board 202 more orderly and convenient. Workers can accurately install the two materials into their corresponding installation layers according to pre-designed positions, improving production efficiency and reducing installation difficulty and error rate.

[0038] like Figure 2 and Figure 4 As shown, the upper and lower side walls of the fixing frame 3 are provided with several clamping plates 4, and the clamping plates 4 extend to the inner side of the fixing frame 3 for fixing the sound insulation foam board 202.

[0039] The clamping plate 4 is provided with a plurality of fastening screws 5, and the clamping plate 4 is fixedly connected to the fixing frame 3 by the fastening screws 5.

[0040] The pressure applied by the clamping plate 4 can make the sound insulation foam board 202 fit better with the fixing frame 3 and the honeycomb cardboard 201. The tight fit can reduce the possibility of sound propagating through the gaps between the materials, further improving the overall sound insulation effect of the door panel. Moreover, the good fit helps to give full play to the sound insulation function of the sound insulation foam board, so that the sound waves are absorbed and blocked by the material more during the propagation process.

[0041] In one specific embodiment, the outer diameter of the honeycomb holes on the honeycomb paperboard 201 is 15mm, and the paper wall thickness forming the honeycomb holes is 3mm.

[0042] In one specific embodiment, the overall thickness of the door core filling 2 is 80mm, and the thickness of the honeycomb cardboard 201 is 20mm.

[0043] The specific combination of size and thickness allows the door core filling, composed of honeycomb cardboard 201 and sound-absorbing foam board 202, to achieve a relatively optimized state for sound absorption and reflection in specific frequency bands. This size configuration can be tailored to the door panel's intended use, specifically addressing common interfering sound frequency bands to meet sound insulation needs in different environments.

[0044] like Figure 1 As shown, the door panel 1 includes: a panel 101 located on the front and rear sides of the door panel 1, and a sealing strip 102 located on the upper and lower sides of the door panel 1. Each side of the panel 101 is provided with a bent portion, which cooperates with another panel 101 to form the left and right sides of the door panel 1.

[0045] A door lock mounting plate 103 is provided on the bent portion of a panel 101. The door lock mounting plate 103 is located inside the door panel 1, and an opening is provided on the bent portion to cooperate with the door lock mounting plate 103.

[0046] A bend is provided on one side of panel 101, and the two bends work together to form a stable connection structure on the left and right sides of door panel 1. This design increases the strength and rigidity of the door panel edges, making it better resistant to external impacts and pressures, reducing the risk of deformation or damage to the door panel during daily use, and extending the door panel's service life.

[0047] like Figure 2 As shown, the fixed frame 3 has a door lock clearance opening 301, which is used to cooperate with the door lock mounting plate 103.

[0048] like Figure 4 As shown, an aerogel felt 302 is provided on the outer circumferential edge of the fixing frame 3, and an installation groove for cooperating with the aerogel felt 302 is provided on the fixing frame 3.

[0049] The aerogel felt 302 is located between the fixed frame 3 and the door panel 1, and can play a role in shock absorption, heat insulation and sound insulation, so as to avoid gaps between the fixed frame 3 and the door panel 1, which would affect the overall sound insulation effect of the door panel 1.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
