The use of "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, or implicitly specifying the number or order of the technical features indicated.

[0026] In the description of the present invention, it should be noted that terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0028] Reference Figures 1 to 4 As shown, an embodiment of the present invention provides a car carpet foam structure, including a body 100 and a foam layer 200 .

[0029] A foaming groove 110 is provided at the bottom of the main body 100, and the foaming groove 110 is concave upward. A plurality of spaced protrusions 120 are provided on the top of the foaming groove 110, and each protrusion 120 protrudes downward. The downward protrusion distance of each protrusion 120 is less than the depth of the foaming groove 110 in the up and down directions.

[0030] The foaming groove 110 is filled with a foaming layer 200 , and the foaming layer 200 is bonded to the side wall and the top wall of the foaming groove 110 .

[0031] A foam layer 200 is filled in the foam groove 110 of the automotive carpet body 100, and a plurality of protrusions 120 in the foam groove 110 are used to increase the bonding area between the foam layer 200 and the foam groove 110. The outer wall of the protrusion 120 forms a vertical bonding surface with the foam layer 200, and the top wall of the foam groove 110 forms a horizontal bonding surface with the foam layer 200. The vertical bonding surface and the horizontal bonding surface provide adhesion in different directions, which helps to improve the bonding stability between the foam groove 110 and the foam layer 200, making the combination of the foam layer 200 and the body 100 more secure and preventing the foam layer 200 from loosening.

[0032] In some embodiments, reference Figure 1 As shown, at least two protrusions 120 protrude downwards at different distances.

[0033] Arranging multiple protrusions 120 with different protrusion distances in the foaming groove 110 helps to form vertical bonding surfaces of different areas between the multiple protrusions 120 and the foaming layer 200. The multiple protrusions 120 form different adhesion forces on the foaming layer 200 to avoid stress concentration.

[0034] In some embodiments, reference Figure 1 As shown, the distance that each protrusion 120 protrudes downward is called the protrusion distance, and the distance from each protrusion 120 to the center position of the foaming groove 110 is called the deviation distance. The protrusion distance is negatively correlated with the deviation distance.

[0035] Since a vertical bonding surface is also formed between the side wall of the foaming groove 110 and the foaming layer 200, the protruding distance of the protrusion 120 at the center position farther away from the foaming groove 110 can be smaller, while the protrusion 120 near the center position of the foaming groove 110 needs to provide a larger vertical bonding area, so the protruding distance of the protrusion 120 near the center position of the foaming groove 110 is larger.

[0036] In some embodiments, reference Figure 3 As shown, the protruding distance of each protrusion 120 is less than half of the depth of the foaming groove 110 in the vertical direction.

[0037] Avoid the protrusion distance of the bump 120 being too large, which may cause the thickness of the foam layer 200 at this position to be too low, thereby affecting the noise reduction and vibration reduction effects of the foam layer 200 .

[0038] In some embodiments, reference Figure 3 As shown, the cross-sectional area of ​​each bump 120 gradually increases from bottom to top.

[0039] Each bump 120 is in the shape of a pyramid with a larger top and a smaller bottom, which is easy to produce. After the foaming layer 200 is filled into the foaming groove 110 , the foaming layer 200 can flow along the outer wall of the bump 120 , which helps to combine the foaming layer 200 with the outer wall of the bump 120 .

[0040] In some embodiments, reference Figure 3 As shown, a first rounded corner 121 is provided at the corner of each bump 120 .

[0041] The corners of the bump 120 adopt first rounded corners 121 to avoid gaps formed between the foam layer 200 and the corners of the bump 120 due to sharp corners, which helps the foam layer 200 to be closely combined with the first rounded corners 121 and improve the adhesion between the corners of the bump 120 and the foam layer 200.

[0042] In some embodiments, reference Figure 3 As shown, a second rounded corner 122 is provided between the top edge of each protrusion 120 and the top side wall of the foaming groove 110 .

[0043] The top edge of the bump 120 and the top sidewall of the foaming groove 110 have a second rounded corner 122 , which helps the foaming layer 200 to be tightly bonded to the second rounded corner 122 and improves the adhesion between the top edge of the bump 120 and the foaming layer 200 .

[0044] In some embodiments, reference Figure 4 As shown, the corners of the foaming groove 110 are provided with third rounded corners 111 .

[0045] The third rounded corners 111 of the foaming groove 110 help the foaming layer 200 to be tightly combined, thereby improving the adhesion between the foaming groove 110 and the foaming layer 200 .

[0046] In some embodiments, reference Figure 1 and Figure 2 As shown, the bottom wall of the body 100 and the bottom wall of the foaming layer 200 are flush.

[0047] The foaming layer 200 and the main body 100 form a whole, so as to prevent the foaming layer 200 from being loosened due to external scratches in subsequent processes after it protrudes.

[0048] The utility model also provides an automobile carpet, comprising the automobile carpet foaming structure as described in the above embodiment.

[0049] A foam layer 200 is filled in the foam groove 110 of the automotive carpet body 100, and a plurality of protrusions 120 in the foam groove 110 are used to increase the bonding area between the foam layer 200 and the foam groove 110. The outer wall of the protrusion 120 forms a vertical bonding surface with the foam layer 200, and the top wall of the foam groove 110 forms a horizontal bonding surface with the foam layer 200. The vertical bonding surface and the horizontal bonding surface provide adhesion in different directions, which helps to improve the bonding stability between the foam groove 110 and the foam layer 200, making the combination of the foam layer 200 and the body 100 more secure and preventing the foam layer 200 from loosening.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
