[0031] Reference below Figure 1-Figure 4 A carpet tile assembly 100 according to an embodiment of the present invention is described.

[0032] Reference Figures 1 to 4 According to an embodiment of the present invention, a carpet pad assembly 100 includes a pad 10 and a flexible material piece 20 .

[0033] The cushion block 10 is suitable for being installed on a carpet to support the carpet, and a welding portion 11 is provided on the cushion block 10. The flexible material piece 20 wraps the cushion block 10 and is fixed on the cushion block 10 through the welding portion 11.

[0034] The pad 10 is fixed on the back of the carpet, and is located between the carpet and the vehicle body. The pad 10 is used to support the carpet and keep the carpet in a fixed shape to avoid deformation of the carpet, such as wrinkles caused by deformation of the carpet.

[0035] The flexible material piece 20 wraps the cushion block 10, and the flexible material piece 20 has a certain flexibility. The flexible material piece 20 can be a fabric, such as a non-woven fabric, a flannel or a felt. The flexible material piece 20 can also be a foam, such as a polyurethane foam or a polyethylene foam. The flexible material piece 20 can also be rubber, etc., which will not be described here. The flexible material piece 20 with a certain flexibility wraps the cushion block 10, so as to prevent the cushion block 10 from being squeezed or collided with other surrounding parts to produce abnormal noise.

[0036] In the related art, a carpet is usually placed inside a vehicle, but the carpet has a peculiar smell.

[0037] In the embodiment of the utility model, the flexible material piece 20 is fixed on the pad 10 by the welding part 11. Compared with the solution of fixing the flexible material piece on the pad by glue in the related art, the odor of glue is avoided and the VOC content (Volatile Organic Compounds, the content of volatile organic compounds in materials or products) is reduced, thereby improving the air quality inside the vehicle.

[0038] Among them, the welding part 11 is a structure retained by the welding process, for example, the welding part 11 is a structure retained by the ultrasonic welding process. During the ultrasonic welding process, the ultrasonic welding equipment melts part of the structure of the pad 10 and part of the structure of the flexible material piece 20 through high-frequency vibration, and the melted parts of the pad 10 and the flexible material piece 20 are fused, thereby fixing the flexible material piece 20 on the pad 10; or, the welding part 11 is a structure retained by the hot air welding process. In the hot air welding process, the hot air welding equipment blows hot air to the contact part between the pad 10 and the flexible material piece 20 to melt it, and then press it together; or, the welding part 11 is a structure retained by the hot pressure welding or laser welding process, and the effect is to fix the flexible material piece 20 on the pad 10, which will not be repeated here.

[0039] Specifically, the flexible material piece 20 wraps the pad 10, that is, the flexible material piece 20 covers at least one side of the pad 10, for example, the flexible material piece 20 covers the side of the pad 10 facing away from the carpet, and the carpet is located above the pad 10, that is, the flexible material piece 20 covers the bottom surface of the pad 10, and the flexible material piece 20 has a certain flexibility, so that the pad 10 will not produce abnormal noise with other sheet metal parts below; or, the flexible material piece 20 wraps the entire pad 10, and the flexible material piece 20 covers the entire surface of the pad 10.

[0040] According to the carpet pad assembly 100 of the embodiment of the utility model, the flexible material piece 20 is fixed to the pad 10 by the welding part 11. Compared with the solution of fixing the flexible material piece to the pad by glue in the related art, the odor of glue is avoided, the VOC content is reduced, and the air quality inside the vehicle is improved.

[0041] Reference Figure 1 In some embodiments, there are multiple welding portions 11 , and the multiple welding portions 11 are arranged at intervals along the circumferential direction of the cushion block 10 .

[0042] The welding part 11 is a structure left by the welding process. The welding process is performed at multiple locations on the cushion block 10 , thereby leaving multiple welding parts 11 arranged at intervals to fix the flexible material piece 20 on the cushion block 10 .

[0043] In the above solution, the flexible material piece 20 is fixed on the pad 10 by providing multiple welding parts 11. The multiple welding parts 11 are dispersedly arranged, which improves the stability of the flexible material piece 20. At the same time, compared with the solution in the related art where the welding parts surround the pad in a whole circle, the cost is reduced.

[0044] Reference Figure 1 In some embodiments, a plurality of welding portions 11 are disposed on the side of the cushion block 10 facing the carpet, and the plurality of welding portions 11 are spaced apart along the edge of the cushion block 10 , and a distance between two adjacent welding portions 11 is L1, 5cm≤L1≤10mm.

[0045] The pad 10 is located on one side of the carpet, and the carpet is usually located above the pad 10. The pad 10 is located below the carpet to play the role of the pad 10. The edge of the pad 10 surrounds the circumferential direction of the pad 10, and a plurality of welding parts 11 are arranged at intervals along the edge of the pad 10 to fix the flexible material piece 20 on the pad 10.

[0046] In the above scheme, by arranging multiple welding parts 11 on the side of the pad 10 facing the carpet, after the pad 10 is fixed on the carpet, the carpet covers the welding parts 11, so that the overall appearance of the carpet pad assembly 100 is more consistent and more beautiful, and multiple welding parts 11 are arranged along the edge of the pad 10, which can reduce the expansion area of ​​the flexible material part 20, reduce the material of the flexible material part 20, and reduce the cost. The distance L1 between two adjacent welding parts 11 is controlled within the range of 5 to 10 mm, reducing the number of welding parts 11 and reducing the welding cost, while allowing the flexible material part 20 to better fit the surface of the pad 10.

[0047] For example, the distance L1 between two adjacent welding portions 11 is 5 mm; or, the distance L1 between two adjacent welding portions 11 is 6 mm; or, the distance L1 between two adjacent welding portions 11 is 7 mm; or, the distance L1 between two adjacent welding portions 11 is 8 mm; or, the distance L1 between two adjacent welding portions 11 is 9 mm; or, the distance L1 between two adjacent welding portions 11 is 10 mm.

[0048] Reference Figure 1 In some embodiments, the minimum distance between the welding portion 11 and the edge is L2, 5cm≤L2≤30mm.

[0049] The welding portion 11 is spaced apart from the edge, and a distance L2 between the welding portion 11 and the edge is a distance between the welding portion 11 and the nearest edge.

[0050] In the above scheme, by setting the minimum distance L2 between the welding portion 11 and the edge within the range of 5 to 30 mm, the welding portion 11 has a larger setting space, which facilitates the welding setting operation. At the same time, it can be understood that the minimum distance L2 between the welding portion 11 and the edge is less than or equal to 30 mm, and there are parts on the pad 10 that are not covered by the flexible material piece 20. The parts on the pad 10 that are not covered by the flexible material piece 20 can be used to connect the carpet, making the overall structure more reasonable.

[0051] Specifically, the carpet is adhered to the portion of the cushion block 10 that is not covered by the flexible material piece 20, so that the cushion block 10 is fixed on the carpet.

[0052] In some embodiments, the welding portion 11 is configured as an ultrasonic welding portion, the shape of the ultrasonic welding portion is configured as a circle or a rectangle, the depth of the welding portion 11 is H, and 3 mm ≤ H ≤ 4 mm.

[0053] The welding part 11 is a structure left by the ultrasonic welding process. During the ultrasonic welding process, the ultrasonic welding equipment melts part of the structure of the cushion block 10 and part of the structure of the flexible material piece 20 through high-frequency vibration, and the melted parts of the cushion block 10 and the flexible material piece 20 are fused, thereby fixing the flexible material piece 20 on the cushion block 10. In the ultrasonic welding process, the welding head on the ultrasonic welding equipment applies a certain pressure to the cushion block 10, and the melted cushion block 10 is deformed.

[0054] In the above scheme, by setting the welding part 11 as an ultrasonic welding part, the ultrasonic welding process is used to melt the flexible material piece 20 and the pad 10, so that the pad 10 is connected to the flexible material piece 20. The method is simple and fast, and the production efficiency is improved. At the same time, the welding part 11 has a certain depth, and the depth H of the welding part 11 is in the range of 3 to 4 mm. The pressure applied by the welding head makes the connection between the pad 10 and the flexible material piece 20 more stable.

[0055] Specifically, the depth H of the welded portion 11 is 3 mm; or, the depth H of the welded portion 11 is 3.5 mm; or, the depth H of the welded portion 11 is 4 mm.

[0056] Specifically, the shape of the ultrasonic welding part is rectangular, with a width of 10 mm and a length of 25 mm.

[0057] In some embodiments, the material of the cushion block 10 is polypropylene or polyurethane.

[0058] The material of the cushion block 10 may be EPP (Expanded Polypropylene) or PU (Polyurethane), making full use of the performance of the EPP or PU material itself.

[0059] In the above scheme, by using the cushion block 10 of EPP material or the cushion block 10 of PU material, the good compression resistance and high stability of the EPP material or the PU material are fully utilized, and the cushion block 10 of the EPP material or the cushion block 10 of the PU material is not easy to deform or age.

[0060] In some embodiments, the flexible material piece 20 is made of non-woven fabric.

[0061] Among them, non-woven fabric is a fabric directly made of short fibers or filaments through mechanical, thermal or chemical bonding.

[0062] In the above scheme, by using the flexible material piece 20 made of non-woven fabric, the cost is reduced and the weight is lightened by taking advantage of the low cost and light weight of the non-woven fabric.

[0063] In some embodiments, the cushion block 10 is made of polypropylene or polyurethane, and the flexible material piece 20 is made of non-woven fabric.

[0064] In the above solution, the material of the cushion block 10 is set to polypropylene or polyurethane, and the material of the flexible material piece 20 is set to non-woven fabric, which reduces the overall weight and reduces the cost.

[0065] Reference Figure 1 In some embodiments, the cushion block 10 has a first edge 12 and a second edge 13, the first edge 12 and the second edge 13 are configured as straight lines, and a third edge 14 is provided between the first edge 12 and the second edge 13, and the third edge 14 is configured as a curve.

[0066] The first edge 12 , the second edge 13 and the third edge 14 are arranged in sequence, one end of the third edge 14 is connected to the first edge 12 , and the other end is connected to the second edge 13 , and the third edge 14 is located between the first edge 12 and the second edge 13 .

[0067] In the above solution, by setting the third edge 14 as a curve, the third edge 14 of the curve structure adapts to the internal structure of the vehicle, so that the carpet pad assembly 100 adapts to the corners of the interior space of the vehicle, thereby improving the adaptability.

[0068] Reference Figure 2 In some embodiments, a weight-reducing groove 15 is provided on the cushion block 10 , and there are a plurality of weight-reducing grooves 15 , which are spaced apart on the side of the cushion block 10 away from the carpet.

[0069] The weight-reducing groove 15 is a groove structure on the cushion block 10 , the carpet is located on one side of the cushion block 10 , and the weight-reducing groove 15 is arranged on the side of the cushion block 10 away from the carpet.

[0070] In the above scheme, a plurality of weight-reducing grooves 15 are provided on the side of the cushion block 10 facing away from the carpet, and the weight-reducing grooves 15 are utilized to reduce the weight of the cushion block 10, thereby reducing the material usage of the cushion block 10 and reducing the cost. The weight-reducing grooves 15 are provided in plurality and are spaced apart, thereby maintaining the overall strength of the cushion block 10 and avoiding local collapse of the cushion block 10.

[0071] Reference Figure 2 In some embodiments, there are multiple pads 10, and the multiple pads 10 are arranged on the carpet at intervals; wherein, at least some of the pads 10 have a first side 16 and a second side 17, the first side 16 faces the carpet, and the second side 17 faces away from the carpet, and a third side 18 is also provided between the first side 16 and the second side 17, and the third side 18 is at least partially constructed as an arc portion 181.

[0072] Among them, a plurality of pads 10 are arranged on the carpet, and the plurality of pads 10 are respectively located at different positions of the carpet, so as to provide a better supporting effect for the carpet. The first side 16 of the pad 10 is used to support the carpet, and the second side 17 of the pad 10 is the opposite side of the first side 16. The pad 10 has a certain thickness, and the third side 18 is arranged between the first side 16 and the second side 17. One end of the third side 18 is connected to the first side 16, and the other end of the third side 18 is connected to the second side 17.

[0073] In the above solution, by configuring at least part of the third side surface 18 as the arc-shaped portion 181 , the arc-shaped structure of the arc-shaped portion 181 is utilized to make the flexible material piece 20 fit better with the cushion block 10 , thereby making the overall structure more compact.

[0074] Specifically, the third side surface 18 may be partially configured as the arc-shaped portion 181 , or may be entirely configured as the arc-shaped portion 181 .
