[0032] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0033] The following will refer to the attached Figure 1 -Attached Figure 3 The carpet assembly 100 of the embodiment of the present application is described in detail with reference to the embodiments. The carpet assembly 100 is applied to a vehicle, and the carpet assembly 100 is used to install a seat of the vehicle.

[0034] The carpet assembly 100 according to the embodiment of the present application includes: a carpet body 1 , a mounting bracket 2 and a cover assembly 3 .

[0035] Among them, the seat is installed on the carpet main body 1, and an avoidance hole 101 is provided on the carpet main body 1. The avoidance hole 101 is used to avoid the mounting bracket 2, and the mounting bracket 2 is arranged at the avoidance hole 101. The mounting bracket 2 is connected and cooperated with the seat (such as the seat bracket) to improve the installation reliability of the seat at the carpet assembly 100.

[0036] Combine Figure 1 and Figure 2 As shown, the cover assembly 3 is covered on the mounting bracket 2 and blocks the avoidance hole 101, and the cover assembly 3 is provided with a noise reduction portion 32, which is used to absorb vibration to achieve noise reduction, so as to reduce the noise transmitted from the carpet assembly 100 to the passenger compartment.

[0037] It should be noted that the mounting bracket 2 is typically constructed as a sheet metal component, and through the mounting bracket 2, it cooperates with the seat to enhance the seat's mounting strength on the carpet assembly 100. The carpet body 1 is provided with a clearance hole 101, and the mounting bracket 2 is positioned at the clearance hole 101. The cover assembly 3 shields the mounting bracket 2 and the clearance hole 101, thereby reducing noise energy at the clearance hole 101 and ensuring the NVH level in the passenger compartment.

[0038] To enhance the user experience, vehicles often integrate features like massage, storage, and leg rests into their seats. This results in a specific structure in the lower area of ​​the seat, which occupies a certain amount of space in the Z direction (i.e., vertical direction). This leaves insufficient room for hand manipulation under the seat, making it impossible to install the seat from the Z direction. This typically requires installation from the lateral X direction. In related technology, to ensure the installation strength of the seat bracket, the bracket must be rigidly connected to the supporting sheet metal (such as the aforementioned mounting bracket), requiring a relief structure in the carpet. This allows chassis wind noise and tire noise to be transmitted into the vehicle through the relief structure, impacting the vehicle's NVH performance.

[0039] In this application, the cover assembly 3 is covered at the avoidance hole 101, and the noise reduction part 32 at the cover assembly 3 weakens the noise energy transmitted to the side of the vehicle through the avoidance hole 101 to ensure the NVH level in the vehicle, thereby improving the user's driving experience.

[0040] like Figure 2 As shown, in some embodiments of the present application, the cover assembly 3 includes a cover body 31 , the cover body 31 has an accommodating cavity opened to one side of the avoidance hole 101 , and the noise reduction portion 32 is filled in the accommodating cavity.

[0041] Among them, the cover body 31 is a carrier for accommodating the noise reduction part 32, and the cover body 31 can be fixed on the carpet body 1 to arrange the noise reduction part 32 in the area corresponding to the avoidance hole 101, so as to facilitate the noise reduction part 32 to weaken the noise energy transmitted to the side of the vehicle through the avoidance hole 101.

[0042] It can be understood that the cover body 31 serves as a mounting carrier for the noise reduction portion 32, and the cover body 31 is used to cover the avoidance hole 101, so that the cover body 31 can be constructed as a component with a certain structural strength such as a plastic part or a sheet metal part to enhance the structural strength of the carpet assembly 100 at the cover component 3 and avoid damage to the cover component 3.

[0043] It should be noted that the shape of the cover body 31 is not specifically limited here, and it only needs to be able to cover the mounting bracket 2 and block the avoidance hole 101, and the shape of the cover body 31 needs to be compatible with the shape of the carpet body 1.

[0044] Reference Figure 2 In the cross-sectional view of the carpet assembly 100, the carpet body 1 is arranged in a Z shape, and the avoidance hole 101 on the carpet body 1 is arranged at the corner transition position of the Z-shaped carpet body 1. At this time, the cover body 31 can be arranged in a "V" shape, and the opening of the "V" shape faces one side of the carpet body 1, so that the cover body 31 is adapted to the shape of the carpet body 1 and the arrangement position of the avoidance hole 101.

[0045] like Figure 2 As shown, in a specific embodiment of the present application, the cover body 31 includes a first plate segment 312 and a second plate segment 313, and the first plate segment 312 and the second plate segment 313 are arranged at an angle to each other, and the angle between the first plate segment 312 and the second plate segment 313 is set to an obtuse angle, thereby configuring the cover body 31 to be arranged in a "V" shape, so that the cover assembly 3 can avoid the mounting bracket 2 while ensuring the shielding effect of the cover body 31 on the avoidance hole 101.

[0046] Furthermore, the cover body 31 also includes a flange 314, which is arranged on the first plate segment 312 and the second plate segment 313, and extends from the outer peripheral edge of the first plate segment 312 and the second plate segment 313 toward the side of the carpet body 1. The flange 314 cooperates with the first plate segment 312 and the second plate segment 313 to define a receiving structure (i.e., the above-mentioned receiving cavity) that is open to the carpet body 1 and the avoidance hole 101.

[0047] like Figure 2 As shown, in some embodiments of the present application, the cover assembly 3 further includes a packaging layer 33, which is arranged at the open end of the cover body, and the packaging layer 33 is used to encapsulate the noise reduction portion 32 in the accommodating cavity, thereby constraining the noise reduction portion 32 in the accommodating cavity through the packaging layer 33.

[0048] It is understood that the encapsulation layer 33 can cooperate with the end of the cover body 31 on the open side to fix the encapsulation layer 33 to the cover body 31. In particular, since the cover body 31 is open to the carpet body 1 and the avoidance hole 101 located therebelow, if the noise reduction portion 32 cannot be restrained, there is a risk that the noise reduction portion 32 will fall off the cover body 31. The encapsulation layer 33 in this application can effectively prevent the noise reduction portion 32 from falling off the cover body 31.

[0049] In a further embodiment of the present application, the encapsulation layer 33 is constructed as a non-woven fiber layer. The non-woven fiber layer can constrain the noise reduction portion 32 filled in the accommodating cavity and can also leak the noise energy at the avoidance hole 101 to the side of the accommodating cavity, thereby weakening the noise energy through the noise reduction portion 32 and preventing vibration of the cover assembly 3.

[0050] It should be noted that the packaging layer 33 is not limited to a non-woven fiber layer, but can also be made of other materials with the property of allowing noise energy to pass through. That is to say, the packaging layer 33 can ensure that the noise reduction part 32 filled in the accommodating cavity of the cover body 31 does not fall off, and allows the noise energy at the avoidance hole 101 to leak to the side of the noise reduction part 32.

[0051] like Figure 3 As shown, in some embodiments of the present application, the noise reduction portion 32 includes a plurality of noise reduction units 321, and the plurality of noise reduction units 321 are arranged in an array in the accommodating cavity, so that the noise energy can be weakened by the plurality of noise reduction units 321, thereby improving the noise energy weakening effect of the noise reduction portion 32.

[0052] At the same time, when the multiple noise reduction units 321 arranged in the accommodating cavity are arranged in an array, the noise reduction units 321 in the accommodating cavity are arranged regularly, which can enhance the structural strength of the cover assembly 3, thereby enhancing the anti-deformation ability of the cover assembly 3 and avoiding damage to the cover assembly 3 due to external force.

[0053] It should be noted that carpet assembly 100 is a structural assembly in the passenger compartment for users to step on or place items on, and that cover assembly 3 is positioned near the driver's legs. The aforementioned "external forces" refer to forces acting on cover assembly 3, such as forces generated by users stepping on cover assembly 3 or by objects placed on cover assembly 3.

[0054] In the related art, the strength of the cover structure is usually improved by adding reinforcing ribs to the cover structure, which leads to a complex design of the cover structure and increases the difficulty of processing and producing the cover structure.

[0055] In the present application, multiple noise reduction units 321 are arranged in an array in the accommodating cavity to improve the structural strength of the cover assembly 3, thereby improving the trampling resistance of the cover body 31. This eliminates the need to add reinforcing structures such as reinforcing ribs to the cover body 31, thereby reducing the difficulty of designing and producing the cover body 31.

[0056] Reference Figure 3 , Figure 3 It is a cross-sectional schematic diagram of the cover assembly 3 at a certain position in the Z direction. Figure 3 The figure shows a cover body 31 and a plurality of noise reduction units 321 arranged inside the cover body 31. The cross section of each noise reduction unit 321 is arranged in a regular hexagon, so that the multiple noise reduction units 321 have a topological honeycomb structure inside the cover body 31 to improve the overall strength of the cover assembly 3.

[0057] It should be noted that the cross-sectional shape of each noise reduction unit 321 is not limited to a regular hexagon, but can also be a triangle, a square, a regular polygon, etc. The shape of the noise reduction unit 321 is not limited here, and the cross-sectional shape and topology of the noise reduction unit 321 can be designed according to the strength requirements of the cover assembly 3.

[0058] like Figure 2 As shown, in some embodiments of the present application, the noise reduction portion 32 includes multiple noise reduction layers, and the multiple noise reduction layers are stacked in the accommodating cavity along the opening direction of the accommodating cavity toward the side of the encapsulation layer 33, so that a multi-level noise reduction structure can be formed in the accommodating cavity to weaken the noise energy multiple times in the transmission path of the noise energy, thereby improving the noise reduction effect of the noise reduction portion 32 on the noise energy.

[0059] Reference Figure 2 It should be noted that the shape of the noise reduction layer matches that of the cover body 31, allowing the layers to be stacked within the housing cavity. Furthermore, there are at least two noise reduction layers. This allows the multiple layers to sequentially attenuate noise energy along the noise energy transmission path, thereby enhancing the noise reduction effect of the noise reduction portion 32.

[0060] It is understandable that in the transmission path of noise energy, the noise reduction structure has limited effect on weakening the noise energy each time. By setting up multiple noise reduction layers, the noise energy can be weakened multiple times in the transmission path, thereby significantly reducing the noise energy that can be transmitted to the passenger compartment, effectively ensuring the NVH level inside the vehicle (i.e., the passenger compartment), and improving the user's driving experience.

[0061] In some embodiments of the present application, the multiple noise reduction layers include: at least one first noise reduction layer 322 and at least one second noise reduction layer 323. It should be noted that the first noise reduction layer 322 and the second noise reduction layer 323 have different noise reduction effects on noise energy. By providing multiple noise reduction layers, sufficient noise reduction can be achieved, thereby improving the noise reduction effect of the noise reduction unit 32 on noise energy.

[0062] In some embodiments of the present application, the first noise reduction layer 322 is filled with vibration particles (not shown), and the vibration particles are suitable for vibrating in the first noise reduction layer 322, so that the low-frequency noise energy in the noise energy is consumed by the vibration of the vibration particles to weaken the noise energy.

[0063] It can be understood that when the noise energy is transmitted to the first noise reduction layer 322, the noise energy excitation causes the vibration particles to vibrate nonlinearly, so that the irregular vibration of the vibration particles has an effect on the medium and low frequency noise energy, thereby reducing the sound pressure level of the noise and improving the noise reduction effect.

[0064] It should be noted that there are multiple vibration particles, and the vibration motion of the multiple vibration particles is irregular, so as to consume low-frequency noise energy. At the same time, "low-frequency vibration" generally refers to vibration with a frequency below 6Hz.

[0065] In some embodiments of the present application, the second noise reduction layer 323 is filled with fibers, which can absorb and consume high-frequency noise energy, thereby attenuating the noise energy through the second noise reduction layer 323. It should be noted that "high-frequency vibration" generally refers to vibration with a frequency above 1000 Hz.

[0066] Reference Figure 2 As shown, in a specific embodiment of the present application, a first noise reduction layer 322 and a second noise reduction layer 323 are simultaneously disposed in the accommodating cavity. The first noise reduction layer 322 and the second noise reduction layer 323 are each one, and the second noise reduction layer 323 is stacked and arranged on the side of the first noise reduction layer 322 facing the encapsulation layer 33. Thus, when the vibration energy at the avoidance hole 101 is transmitted through the encapsulation layer 33, it is first transmitted to the second noise reduction layer 323 and then to the first noise reduction layer 322. The first noise reduction layer 322 and the second noise reduction layer 323 respectively attenuate noise energy of different vibration frequencies, enabling the noise reduction portion 32 to effectively attenuate noise energy of different vibration frequencies (e.g., high frequency, low frequency, etc.).

[0067] It should be noted that multiple first noise reduction layers 322 and multiple second noise reduction layers 323 may be disposed within the accommodating cavity. The first noise reduction layers 322 and the second noise reduction layers 323 may be arranged in alternating layers, or multiple first noise reduction layers 322 and multiple second noise reduction layers 323 may be stacked and arranged separately. When multiple first noise reduction layers 322 and multiple second noise reduction layers 323 are disposed within the accommodating cavity, the stacking arrangement of the first noise reduction layers 322 and the second noise reduction layers 323 may be designed based on noise reduction requirements and is not specifically limited herein.

[0068] In some embodiments of the present application, the vibration particles include at least sponge particles and rubber particles, so that the vibration particles include particle structures made of at least two different materials (i.e., sponge particles and rubber particles). By mixing and filling particle structures of multiple materials in the first noise reduction layer 322, problems such as abnormal noise in the first noise reduction layer 322 can be avoided, and the vibration particle layer's consumption effect on low-frequency noise energy can be further improved.

[0069] It should be noted that, in other embodiments of the present application, the particle structure included in the vibration particle layer is not limited to sponge particles and rubber particles, but may also include particle structures of other materials (such as rubber particles, etc.).

[0070] In some embodiments of the present application, the fibers filling the second noise reduction layer 323 may be PET (polyethylene terephthalate) fibers; in some embodiments of the present application, the fibers filling the second noise reduction layer 323 may also be PP (polypropylene) fibers; in some embodiments of the present application, the fibers filling the second noise reduction layer 323 may also be a mixture of PP and PET fibers. In this way, the fibers can absorb and dissipate high-frequency noise energy transmitted to the second noise reduction layer 323.

[0071] It should be noted that the fibers may also include fiber structures made of other polymeric materials, and are not limited to the above-mentioned PP fibers and PET fibers.

[0072] like Figure 3 As shown, in some embodiments of the present application, the cover body 31 is provided with a snap-fit ​​portion 311, which is used to snap-fit ​​with the seat. It is understood that when the seat is mounted on the carpet body 1, the cover body 31 can snap-fit ​​with the seat via the snap-fit ​​portion 311, thereby securing the cover assembly 3 to the carpet body 1.

[0073] It should be noted that the seat's snap-fit ​​structure can be formed on the seat rail 200, which is arranged on the carpet body 1. The seat rail 200 is arranged adjacent to the cover assembly 3, so that the cover assembly 3 can be further secured to the carpet body 1 through the snap-fit ​​connection between the seat rail 200 and the cover assembly 3. Furthermore, the snap-fit ​​connection method is simple and can reduce the difficulty of assembling the cover assembly 3.

[0074] Among them, the snap-fitting part 311 can be constructed as a buckle, a hook, a slot, etc. Correspondingly, the seat is also provided with a snap-fitting fitting part that is compatible with the structure of the snap-fitting part 311. The specific structure of the snap-fitting part 311 is not limited here.

[0075] In some embodiments of the present application, mounting bracket 2 includes a first bracket 21 and a second bracket 22. First bracket 21 is positioned within avoidance hole 101 of carpet assembly 100 and can be secured to the floor sheet metal structure. Second bracket 22 is positioned on a side of first bracket 21 adjacent to cover assembly 3 and configured to engage with the seat. Cover assembly 3 is positioned on the outside of second bracket 22 (i.e., the side of second bracket 22 facing the passenger compartment).

[0076] It should be noted that the structure of the mounting bracket 2 is not specifically limited here, as long as it can meet the installation strength requirements of the seat.

[0077] Reference Figure 2The process of reducing and consuming noise energy by the carpet assembly 100 according to the present application is described as follows:

[0078] When noise energy is transmitted to one side of the cover assembly 3 through the avoidance hole 101, the noise energy can pass through the packaging layer 33 and cooperate with the second noise reduction layer 323. The second noise reduction layer 323 can absorb and consume high-frequency noise energy. After the noise energy passes through the second noise reduction layer 323, it cooperates with the first noise reduction layer 322. The first noise reduction layer 322 can consume medium and low-frequency noise energy, thereby reducing the sound pressure level of the noise. Finally, the noise is isolated by the cover body (such as a plastic cover, etc.).

[0079] In this way, the noise leaking from the avoidance hole 101 to the passenger compartment side can be effectively processed, thereby avoiding the performance loss caused by the seat being assembled along the X direction and effectively ensuring the NVH level in the vehicle.

[0080] The vehicle carpet assembly 100 according to the embodiment of the present application has at least the following advantages compared to the prior art:

[0081] (1) The carpet assembly 100 weakens the noise energy transmitted from the avoidance hole 101 to the passenger compartment through the cover assembly 3, thereby ensuring the NVH level in the vehicle and improving the user's driving experience;

[0082] (2) The noise reduction unit 32 is composed of a plurality of noise reduction layers stacked together, and can fully consume noise energy of different frequencies.

[0083] (3) The noise reduction units 321 in the cover assembly 3 are arranged in an array in the cover body 31, such as a topological honeycomb structure, so that the multiple noise reduction units 321 in the cover body 31 are arranged regularly, and the structural strength of the cover assembly 3 is improved, so that the cover assembly 3 has good anti-trampling strength.

[0084] According to the vehicle of the embodiment of the present application, the vehicle includes the above-mentioned carpet assembly 100. The carpet assembly 100 can effectively weaken and isolate the wind noise and tire noise at the chassis of the vehicle, reduce the noise energy transmitted to the interior of the vehicle, and thus improve the NVH performance of the entire vehicle.

[0085] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
