Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive supplies technology, specifically to a car floor mat with noise reduction function. Background Technology
[0002] With the development of the automotive industry, consumers have increasingly higher requirements for the driving experience, making in-car noise control a crucial need. In-car noise mainly originates from engine vibration, tire noise, wind noise, and sound transmission from the chassis structure. Traditional car floor mats, often made of single rubber or fiber materials, only serve to prevent dust and protect the original carpet, lacking targeted noise reduction design. They cannot effectively block or absorb noise, causing it to be directly transmitted into the car, affecting the comfort of passengers.
[0003] Meanwhile, traditional car floor mats suffer from insufficient stability: some mats have poor surface anti-slip properties, making them prone to shifting during use; some mats have easily worn and curled edges, resulting in a short lifespan; and most mats lack a dedicated fixing structure, making them prone to slipping when the vehicle is bumpy, affecting not only the user experience but also potentially posing a safety hazard. Furthermore, existing car floor mats with some noise reduction capabilities often use a single sound-absorbing material, limiting their noise reduction frequency range and failing to effectively address high, mid, and low-frequency noise, resulting in unsatisfactory noise reduction effects. Therefore, there is an urgent need for a car floor mat that combines efficient noise reduction, stable fixation, durability, and comfort to meet market demands. Utility Model Content
[0004] The purpose of this invention is to provide a car floor mat with noise reduction function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a car floor mat with noise reduction function, comprising a floor mat, wherein the edge of the floor mat is wrapped with an edge strip;
[0006] Foot pads include a short-pile composite PVC layer, an EVA layer, closed-cell aluminum foam, a noise-reducing layer, and a polyester knitted layer;
[0007] The short-pile composite PVC layer is located above the EVA layer and the two are bonded together. A closed-cell aluminum foam is attached below the EVA layer. The noise reduction layer is embedded inside the closed-cell aluminum foam. A polyester knitted layer is attached below the closed-cell aluminum foam.
[0008] The beneficial effects of this utility model are as follows: noise reduction is achieved through the synergistic effect of a multi-layer structure. The PET sound-absorbing cotton of the noise reduction layer can efficiently absorb mid-to-high frequency noise (such as tire noise and wind noise), the butyl rubber damping sheet can suppress the transmission of low-frequency vibrations (such as chassis resonance) of the floor mat and the vehicle floor, and the double-layer concave-convex convex open-cell PU foam can absorb residual noise in the second time. At the same time, the hollow structure of the closed-cell foam aluminum and the built-in uprights can block the penetration of airborne sound and structural sound. Compared with traditional floor mats, it effectively improves the acoustic environment inside the vehicle.
[0009] The foot pad at the front of the floor mat is connected to the main body by rivets, which can enhance the structural stability of the high-frequency stepping area and prevent local wear and displacement; multiple adhesive blocks on the rear edge can fit tightly to the car interior surface, further fixing the position of the floor mat and preventing it from sliding when the vehicle is bumpy, thus improving safety; the polyester knitted layer at the bottom has strong friction and can fit the original car carpet, reducing the risk of the floor mat shifting as a whole.
[0010] The surface short-pile composite PVC layer combines a soft feel with wear resistance, ensuring comfort while resisting daily scratches, water and stains, and easy cleaning; the EVA layer has good cushioning, absorbing the impact of footsteps and improving ride comfort; the edge trim prevents the edges of the mat from wearing out and curling, extending its service life, and all materials meet automotive interior VOC standards, with no odor release, ensuring healthy use;
[0011] The built-in uprights of closed-cell aluminum foam enhance the overall structural rigidity, preventing the foot pads from collapsing and deforming due to long-term footing. They also support the upper short-pile composite PVC and EVA layers, maintaining the stability of the foot pad shape and balancing cushioning and support.
[0012] A further configuration is provided: a step mat is attached to the front surface of the foot pad.
[0013] The step mat is further configured such that it is connected to the foot pad via rivets.
[0014] A further feature is provided: multiple adhesive blocks are fixedly connected to the rear edge of the foot pad.
[0015] Further configured such that the closed-cell aluminum foam has a hollow structure.
[0016] The configuration is further improved by having multiple uprights evenly spaced inside the closed-cell aluminum foam.
[0017] The noise reduction layer is further configured as follows: the noise reduction layer includes PET sound-absorbing cotton, butyl rubber damping sheet and open-cell PU foam, the PET sound-absorbing cotton is attached to the top surface of the open-cell PU foam, and the butyl rubber damping sheet is attached to the bottom end of the open-cell PU foam.
[0018] The further configuration is as follows: the open-cell PU foam consists of two layers, upper and lower, with the two layers fitting together in a concave-convex shape.
[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0026] Please see Figures 1 to 4 A car floor mat with noise reduction function includes a floor mat 1, and the edge of the floor mat 1 is wrapped with an edge strip 2;
[0027] Foot pad 1 includes a short-pile composite PVC layer 101, an EVA layer 102, a closed-cell aluminum foam 103, a noise reduction layer 104, and a polyester knitted layer 105.
[0028] The short-pile composite PVC layer 101 is located above the EVA layer 102, and the two are bonded together. A closed-cell aluminum foam 103 is attached below the EVA layer 102. The noise reduction layer 104 is embedded inside the closed-cell aluminum foam 103. A polyester knitted layer 105 is attached below the closed-cell aluminum foam 103.
[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the front surface of the foot pad 1 is attached to the step mat 3.
[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the foot pad 3 is connected to the foot pad 1 by rivets.
[0031] In this embodiment, as Figure 3As shown, multiple adhesive blocks 4 are fixedly connected to the rear edge of the foot pad 1.
[0032] In this embodiment, as Figure 4 As shown, closed-cell aluminum foam 103 has a hollow structure.
[0033] In this embodiment, as Figure 4 As shown, multiple uprights are equidistantly arranged inside the closed-cell aluminum foam 103.
[0034] In this embodiment, as Figure 4 As shown, the noise reduction layer 104 includes PET sound-absorbing cotton, butyl rubber damping sheet and open-cell PU foam. The PET sound-absorbing cotton is attached to the top surface of the open-cell PU foam, and the butyl rubber damping sheet is attached to the bottom end of the open-cell PU foam.
[0035] In this embodiment, as Figure 4 As shown, the open-cell PU foam consists of two layers, upper and lower, with the two layers fitting together in a concave-convex shape.
[0036] The noise-reducing car floor mat works as follows:
[0037] When the floor mat 1 is first laid in the designated location in the car interior, the polyester knitted layer 105 at the bottom adheres tightly to the original car carpet due to its high friction, initially limiting the displacement of the floor mat 1; at the same time, the adhesive block 4 on the rear edge of the floor mat 1 is attached to the interior surface, forming a secondary fixation to ensure the overall stability of the floor mat 1; the front foot pad 3 is connected to the main body of the floor mat 1 by rivets, strengthening the structural stability of high-frequency stepping areas, such as the areas where the driver's feet frequently come into contact, and preventing local slippage and wear;
[0038] When the driver steps on the floor mat 1, the surface short-pile composite PVC layer 101 provides a soft touch, while the underlying EVA layer 102 absorbs the impact of stepping through its own elasticity, reducing vibration transmission; at the same time, the EVA layer 102 can initially block some noise, preventing noise from being directly transmitted upwards to the feet.
[0039] Noise and vibration initially treated by the EVA layer 102 are transmitted to the closed-cell aluminum foam 103. Its hollow structure and built-in uprights block the penetration of airborne and structural sound, preventing noise from being transmitted downwards to the vehicle body. The noise reduction layer 104 embedded in the closed-cell aluminum foam 103 further plays its role. The PET sound-absorbing cotton first absorbs mid-to-high frequency noise. The unabsorbed noise and vibration are transmitted to the butyl rubber damping sheet. The damping sheet suppresses vibration and blocks low-frequency sound transmission through its high damping characteristics. Finally, the double-layer concave-convex open-cell PU foam absorbs the residual noise a second time, forming a "absorption-blocking-absorption" noise reduction closed loop to minimize in-vehicle noise.
[0040] The edge banding strip 2 prevents the edges of the foot pad 1 from wearing or curling due to friction. The upright structure of the closed-cell aluminum foam 103 keeps the overall shape of the foot pad 1 stable and prevents it from collapsing or deforming. The waterproof and stain-resistant properties of the short-pile composite PVC layer 101 can resist stains and water stains in daily use. Cleaning only requires wiping or washing with water, ensuring that the foot pad 1 maintains a good working condition and functional effect for a long time.
