[0002] Flooring, as a conventional decorative material, is becoming increasingly widespread, and people have higher and higher requirements for it. Chinese patent CN219153936U discloses a new type of high-strength soundproof flooring. The composite sound insulation substrate, made primarily of methacrylic prepolymer resin, serves as the base layer of the flooring, ensuring its main sound insulation effect. Simultaneously, a foam layer and a sound insulation combination layer are disposed on the composite sound insulation substrate, thereby dispersing sound transmitted from the floor surface. This patent, to a certain extent, solves the problem of poor sound insulation in existing flooring technologies. In children's rooms or dance studios, soft flooring is often used to prevent falls and injuries. Existing flooring balances both strength and softness. Summary of the Invention

This invention divides the floor into four layers: a sound-insulating base plate, sound-absorbing cotton, a reinforcing plate, and a panel. The sound-insulating base plate, the reinforcing plate, and the panel are connected in sequence. The sound-insulating base plate and the reinforcing plate support the lower surface of the panel, preventing the panel from collapsing after long-term use. Both the sound-insulating base plate and the reinforcing plate are made of high-density foam material wrapped around a metal sound-insulating plate, which has good sound insulation effect and high support strength, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-strength sound-absorbing soft floor, comprising a sound-insulating base plate, sound-absorbing cotton, and a panel. The sound-insulating base plate is internally connected to the sound-absorbing cotton, and a reinforcing plate is connected between the sound-absorbing cotton and the panel. The reinforcing plate has a sound-absorbing cavity. The panel includes a padding layer and a support layer. The support layer is in contact with the upper surface of the reinforcing plate, and the upper surface of the support layer is bonded to the padding layer.

[0005] Preferably, a semi-circular hole is provided at the bottom of the sound-absorbing cavity, and staggered protrusions are connected to the inner wall of the sound-absorbing cavity.

[0006] Preferably, the upper surface of the reinforcing plate is provided with a V-shaped groove, and the lower surface of the support layer is connected with a V-shaped strip, which is bonded to the V-shaped groove.

[0007] Preferably, the lower surface of the support layer is provided with an extension column, which corresponds one-to-one with the sound absorption cavity, and the lower end of the extension column extends into the sound absorption cavity. A support spring is sleeved on the extension column, and the lower end of the support spring is connected to the sound absorption cotton.

[0008] Preferably, the sound-absorbing cotton is provided with a protrusion that matches the sound-absorbing cavity. The protrusion is engaged with the lower end of the sound-absorbing cavity. A semi-cylindrical strip is provided between the protrusions, and the semi-cylindrical strip engages with a semi-circular hole.

[0009] Preferably, the center of the protrusion has a primary sound-absorbing hole and a secondary sound-absorbing hole, which are distributed in a stepped manner, with the secondary sound-absorbing hole extending into the sound-absorbing cotton.

[0010] Preferably, the upper surface of the sound insulation base plate is provided with a locking groove that matches the sound-absorbing cotton, and the sound-absorbing cotton is accommodated in the locking groove.

[0011] Preferably, the edges of the soundproof base plate, the front panel, and the reinforcing plate are all vertically aligned, and the edges of the soundproof base plate, the front panel, and the reinforcing plate are all provided with snap-fit ​​joints.

[0012] Preferably, both the sound insulation base plate and the reinforcing plate are made of high-density foam material wrapped around a metal sound insulation plate.

[0013] Another technical problem to be solved by the present invention is to provide a manufacturing process for a high-strength sound-absorbing soft floor, comprising the following steps:

[0014] S1: Prepare the sound insulation base plate and the reinforcing plate, and cut the sound-absorbing cotton according to the size of the locking groove and the size of the sound-absorbing cavity and semi-circular hole on the reinforcing plate;

[0015] S2: Apply adhesive to the locking groove, insert sound-absorbing cotton into the locking groove, and bond the sound-absorbing cotton to the reinforcing plate;

[0016] S3: Bond the padding layer and the support layer into a panel, apply an adhesive layer to the raised strip on the lower surface of the support layer, attach the support spring to the extension column, and bond the support layer to the reinforcing plate.

[0017] S4: Check if the adhesive area is completely bonded and remove any excess adhesive.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention divides the floor into four layers: sound-insulating base plate, sound-absorbing cotton, reinforcing plate, and panel. The sound-insulating base plate, reinforcing plate, and panel are connected in sequence. The sound-insulating base plate and reinforcing plate support the lower surface of the panel to prevent the panel from collapsing after long-term use. Both the sound-insulating base plate and reinforcing plate are made of high-density foam material wrapped around metal sound-insulating plate, which has good sound insulation effect and high support strength.

[0020] 2. This invention connects sound-absorbing cotton between the sound insulation base plate and the reinforcing plate, and the extension column guides the sound to the sound absorption cavity. The sound absorption cavity isolates the diffusion of the sound, and then the sound-absorbing cotton absorbs the sound, gradually reducing the diffusion of the sound waves, resulting in a good sound reduction effect.

[0021] 3. The present invention uses raised strips inside the sound-absorbing cavity to intercept and weaken sound waves during transmission. The primary and secondary sound-absorbing holes are distributed in a stepped manner to gradually weaken the sound waves. The remaining sound is absorbed by the sound-absorbing cotton, thus enhancing the sound absorption effect.

[0022] 4. In this invention, the upper surface of the support layer is bonded to the cushion layer, and the cushion layer is in direct contact with the user, which can play a protective role when the user falls. At the same time, in order to prevent the support layer from collapsing after long-term use, a support spring is used to assist its restoration and increase the strength of the support layer.

[0023] 5. The present invention increases the connection area by connecting the layers with raised strips, raised platforms and semi-cylindrical strips, thereby preventing the layers from falling off and enhancing the connection strength. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To address the issue of existing flooring in children's rooms or dance studios, which often uses soft flooring to prevent falls, please refer to [link / reference needed]. Figures 1-7 This embodiment provides the following technical solution:

[0034] In this embodiment, the high-strength sound-absorbing soft floor includes a sound-insulating base plate 1, sound-absorbing cotton 2, and a panel 3. The sound-insulating base plate 1 is connected to the sound-absorbing cotton 2, and a reinforcing plate 4 is connected between the sound-absorbing cotton 2 and the panel 3. The reinforcing plate 4 has sound-absorbing cavities 41. The reinforcing plate 4 is a honeycomb-shaped board composed of multiple regular hexagonal sound-absorbing cavities 41. The sound-absorbing cavities 41 reduce the weight of the reinforcing plate 4 while providing support for the panel 3 in the longitudinal direction, thereby enhancing the support and stability of the entire floor. The multiple regular hexagonal sound-absorbing cavities 41 divide the reinforcing plate 4, and local noise is absorbed in the corresponding sound-absorbing cavity 41, reducing the outward spread of sound. The panel 3 includes a cushion layer 31 and a support layer 32. The support layer 32 is in contact with the upper surface of the reinforcing plate 4, and the upper surface of the support layer 32 is bonded to the cushion layer 31. The cushion layer 31 is in direct contact with the user and can provide protection when the user falls.

[0035] In this embodiment, a semi-circular hole 42 is provided at the bottom of the sound-absorbing cavity 41. The semi-circular hole 42 is used to fix the sound-absorbing cotton 2, so that the sound can be absorbed by the sound-absorbing cotton 2. Furthermore, when the sound in a certain sound-absorbing cavity 41 is difficult to be completely absorbed, it can also be conducted to the adjacent sound-absorbing cavity 41 through the semi-circular hole 42 and absorbed a second time. The inner wall of the sound-absorbing cavity 41 is connected with staggered protrusions 43. When the sound waves are transmitted, the protrusions 43 can play an interception role, weaken the sound waves, and achieve the effect of noise reduction.

[0036] In this embodiment, a V-shaped groove 44 is provided on the upper surface of the reinforcing plate 4, and a V-shaped strip 321 is connected to the lower surface of the support layer 32. The V-shaped strip 321 and the V-shaped groove 44 are bonded together. Through the V-shaped strip 321 and the V-shaped groove 44, the connection area between the reinforcing plate 4 and the support layer 32 is increased, and the connection between the support layer 32 and the reinforcing plate 4 is improved.

[0037] In this embodiment, an extension post 322 is provided on the lower surface of the support layer 32. The extension post 322 corresponds one-to-one with the sound absorption cavity 41, and the lower end of the extension post 322 extends into the sound absorption cavity 41. A support spring 323 is sleeved on the extension post 322. The extension post 322 facilitates the propagation of sound into the sound absorption cavity 41. The extension post 322 guides the support spring 323. When the sound wave energy is too large, the sound wave can drive the support spring 323 to vibrate, converting the sound wave into mechanical energy, which serves to eliminate noise. The lower end of the support spring 323 is connected to the sound-absorbing cotton 2. The support spring 323 supports the support layer 32. When the center of the support layer 32 corresponding to the sound absorption cavity 41 is compressed, it can also be reset by the support spring 323, preventing the center of the support layer 32 corresponding to the sound absorption cavity 41 from sinking after long-term use, thus increasing the overall strength of the floor.

[0038] In this embodiment, the sound-absorbing cotton 2 is provided with a protrusion 21 that matches the sound-absorbing cavity 41. The protrusion 21 is engaged with the lower end of the sound-absorbing cavity 41. The protrusion 21 and the sound-absorbing cavity 41 cooperate with each other. The sound-absorbing cavity 41 isolates the sound and absorbs the sound through the protrusion 21. At the same time, the engagement of the protrusion 21 and the sound-absorbing cavity 41 strengthens the connection between the sound-absorbing cotton 2 and the reinforcing plate 4, and prevents the reinforcing plate 4 and the sound-absorbing cotton 2 from being misaligned and separated. A semi-cylindrical strip 22 is provided between the protrusions 21. The semi-cylindrical strip 22 engages with the semi-circular hole 42 and connects the adjacent sound-absorbing cavities 41 through the semi-cylindrical strip 22.

[0039] In this embodiment, the center of the protrusion 21 is provided with a primary sound-absorbing hole 211 and a secondary sound-absorbing hole 212. The primary sound-absorbing hole 211 and the secondary sound-absorbing hole 212 are distributed in a stepped manner. The secondary sound-absorbing hole 212 extends into the sound-absorbing cotton 2. The sound wave diffusion is slowed down by the primary sound-absorbing hole 211 and the secondary sound-absorbing hole 212. The remaining sound is absorbed by the sidewalls of the primary sound-absorbing hole 211 and the secondary sound-absorbing hole 212 and the sound-absorbing cotton 2.

[0040] In this embodiment, the upper surface of the sound insulation base plate 1 is provided with a locking groove 11 that matches the sound-absorbing cotton 2. The sound-absorbing cotton 2 is accommodated in the locking groove 11, and the edge of the locking groove 11 wraps around the sound-absorbing cotton 2 to provide sound insulation for the edge of the sound-absorbing cotton 2. The upper surface of the sound insulation base plate 1 is connected to the edge of the reinforcing plate 4. The sound insulation base plate 1 and the reinforcing plate 4 together support the support layer 32 and improve the strength of the support layer 32. The sound-absorbing cotton 2 is completely in the middle of the floor, which protects the sound-absorbing cotton 2.

[0041] In this embodiment, the edges of the soundproof base plate 1, the panel 3, and the reinforcing plate 4 are all vertically aligned, and the edges of the soundproof base plate 1, the panel 3, and the reinforcing plate 4 are all provided with snap-fit ​​joints 12. When connecting, the floor is connected through the snap-fit ​​joints 12, which facilitates assembly.

[0042] In this embodiment, both the sound insulation base plate 1 and the reinforcing plate 4 are made of high-density foam material wrapped around a metal sound insulation board, which has good sound insulation effect and high support strength.

[0043] To better demonstrate the manufacturing process of high-strength sound-absorbing flexible flooring, this embodiment presents a manufacturing process for high-strength sound-absorbing flexible flooring, including the following steps:

[0044] Prepare the sound insulation base plate 1 and the reinforcing plate 4. Manufacture a metal sound insulation plate according to the mold, and spray a uniform and thick high-density foam material onto the metal sound insulation plate to form an overall frame of the sound insulation base plate 1 and the reinforcing plate 4. Open corresponding slots and holes in the overall frame. Cut the sound-absorbing cotton 2 according to the size of the locking groove 11 and the dimensions of the sound-absorbing cavity 41 and the semi-circular hole 42 on the reinforcing plate 4. The sound-absorbing cotton 2 is not only cut to have an edge that perfectly matches the locking groove 11, but also has raised platforms 21, semi-circular strips 22, and primary sound-absorbing holes 211 and secondary sound-absorbing holes 212. Adhesive is applied to the groove 11. Sound-absorbing cotton 2 is installed into the groove 11. The sound-absorbing cotton 2 is bonded to the reinforcing plate 4. The lower surface and edge of the sound-absorbing cotton 2 are bonded to the sound insulation base plate 1. The upper surface of the sound-absorbing cotton 2 is bonded to the reinforcing plate 4. At the same time, the lower edge of the reinforcing plate 4 is bonded to the sound insulation base plate 1. The padding layer 31 and the support layer 32 are bonded to form the panel 3. Adhesive is applied to the raised strip 43 on the lower surface of the support layer 32. The support spring 323 is sleeved on the extension column 322. The support layer 32 is bonded to the reinforcing plate 4. Check whether the bonding area is completely bonded and remove excess adhesive.

[0045] In summary, the floor consists of four layers: a sound-insulating base plate 1, sound-absorbing cotton 2, a reinforcing board 4, and a panel 3. The sound-insulating base plate 1, reinforcing board 4, and panel 3 are connected sequentially. The sound-insulating base plate 1 and reinforcing board 4 support the lower surface of the panel 3, preventing it from collapsing over time. Both the sound-insulating base plate 1 and reinforcing board 4 are made of high-density foam material wrapped around metal sound-insulating panels, providing excellent sound insulation and high support strength. Sound-absorbing cotton 2 is connected between the sound-insulating base plate 1 and reinforcing board 4. An extension column 322 guides sound to the sound-absorbing cavity 41, which isolates sound diffusion, which is then absorbed by the sound-absorbing cotton 2, gradually reducing sound wave diffusion and achieving good sound attenuation. Raised strips 43 are installed inside the sound-absorbing cavity 41. During sound wave transmission, the raised strip 43 can intercept and weaken the sound waves. The primary sound-absorbing holes 211 and the secondary sound-absorbing holes 212 are distributed in a stepped manner, gradually weakening the sound waves. The remaining sound is absorbed by the sound-absorbing cotton 2, enhancing the sound absorption effect. The upper surface of the support layer 32 is bonded to the soft pad layer 31. The soft pad layer 31 is in direct contact with the user and can play a protective role when the user falls. At the same time, in order to prevent the support layer 32 from collapsing after long-term use, the support spring 323 is used to assist its reset, increasing the strength of the support layer 32. The layers are connected by raised strips 43, raised platforms 21 and semi-cylindrical strips 22, increasing the connection area, preventing the layers from falling off and enhancing the connection strength.
