Description

Technical Field

[0001] This utility model relates to the field of automotive carpet technology, and in particular to a low-VOC composite automotive carpet. Background Technology

[0002] Car carpets are materials used to cover the floor inside a car, primarily serving to protect the interior floor, increase comfort, and enhance aesthetics. They are typically made of various fibers (such as polypropylene, polyester, or nylon), and some also use foam or other filling materials to improve sound insulation and comfort.

[0003] In the prior art, some car carpets have a smooth bottom. Compared with a bottom with texture or adhesive design, a smooth bottom may easily shift after long-term use and cannot be effectively kept in place, thus affecting the driver's user experience. Therefore, a low-VOC composite material car carpet is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a low-VOC composite material car carpet, which aims to improve the problem that the bottom of the existing car carpet is smooth, which makes it easy to shift after long-term use and cannot be effectively kept in place, thus affecting the driver's user experience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A low-VOC composite automotive carpet includes a mat and an outer layer, the outer layer serving as the carpet's outer skin. The mat has an internally fixed filling layer designed to fill the carpet. Reinforcing ribs are fixedly connected to the top of the filling layer to enhance the carpet's strength. Multiple anti-slip patterns are fixedly connected to the bottom of the mat to cooperate with anti-slip blocks, increasing the carpet's bottom friction and reducing displacement. Multiple anti-slip blocks are also fixedly connected to the bottom of the mat. A frame is fixedly connected to the outer side of the mat to protect the carpet's edges. Four fixing components for securing the automotive carpet are provided on the outer side of the frame. As a further description of the above technical solution: The top end of the reinforcing rib is fixedly connected to the inner top of the outer layer. The reinforcing rib is designed to strengthen the carpet. The bottom end of the filling layer is fixedly connected to the inner bottom of the outer layer. The filling layer is designed to fill the carpet. As a further description of the above technical solution: The anti-slip texture and the anti-slip block are interspersed. The anti-slip texture is designed to cooperate with the anti-slip block to increase the friction at the bottom of the carpet and reduce the displacement of the carpet. Both the anti-slip texture and the anti-slip block are made of nitrile rubber. As a further description of the above technical solution: The fixing component includes four fixing strips and four fixing holes. The four fixing strips are located on the outside of the frame, and the four fixing holes are respectively opened inside the four fixing strips. The fixing strips and fixing holes cooperate with each other to facilitate the fixing of the carpet.

[0006] This utility model has the following beneficial effects: In this invention, the anti-slip texture and anti-slip block of nitrile rubber work together to increase the friction at the bottom of the carpet, reduce carpet displacement, and effectively keep the carpet in place, thus avoiding affecting the driver's user experience.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Reference Figures 1 to 3One embodiment of this utility model is a low-VOC composite automotive carpet, comprising a mat 1 and an outer layer 4. The outer layer 4 serves as the outer skin of the carpet. The material of the outer layer 4 is maleic anhydride-grafted polypropylene and ethylene-alkyl acrylate. The network structure formed by the covalent bonds in the maleic anhydride-grafted polypropylene can improve the interaction forces between molecules, reduce the diffusion rate of volatile components inside the material, and reduce the VOCs volatilized from the material. The ethylene-alkyl acrylate has high polarity and adsorption capacity, and can undergo physical adsorption with some organic gases. By adsorbing small molecule gases, the ethylene-alkyl acrylate can reduce the overall VOC release of the material.

[0011] The inner part of the mat 1 is fixedly connected to a filling layer 2, which is designed to fill the carpet. The top of the filling layer 2 is fixedly connected to a reinforcing rib 3, which is designed to strengthen the carpet.

[0012] The top of the reinforcing rib 3 is fixedly connected to the inner top of the outer layer 4. The reinforcing rib 3 is designed to strengthen the carpet. The bottom of the filling layer 2 is fixedly connected to the inner bottom of the outer layer 4. The filling layer 2 is designed to fill the carpet. The fixing components include four fixing strips 8 and four fixing holes 9. The four fixing strips 8 are set on the outside of the frame 7. The four fixing holes 9 are respectively opened inside the four fixing strips 8. The fixing strips 8 and fixing holes 9 cooperate with each other to facilitate the fixing of the carpet.

[0013] like Figure 4 As shown, multiple anti-slip patterns 5 are fixedly connected to the bottom of the mat 1. The anti-slip patterns 5 are designed to cooperate with the anti-slip blocks 6 to increase the friction of the bottom of the carpet and reduce the displacement of the carpet. Multiple anti-slip blocks 6 are fixedly connected to the bottom of the mat 1. A frame 7 is fixedly connected to the outer side of the mat 1. The frame 7 is designed to protect the edge of the carpet.

[0014] Four fixing components for securing the car carpet are provided on the outer side of the frame 7. The anti-slip pattern 5 and the anti-slip block 6 are distributed alternately. Both the anti-slip pattern 5 and the anti-slip block 6 are made of nitrile rubber. The anti-slip pattern 5 is designed to cooperate with the anti-slip block 6 to increase the friction of the bottom of the carpet and reduce the displacement of the carpet.

[0015] Working principle: As a car carpet, mat 1 has a filling layer 2, reinforcing ribs 3, and an outer layer 4. The filling layer 2 is designed to fill the carpet, the reinforcing ribs 3 are to strengthen the carpet, and the outer layer 4 serves as the carpet's outer skin. Its material is maleic anhydride-grafted polypropylene and ethylene-alkyl acrylate. The network structure formed by the covalent bonds in the maleic anhydride-grafted polypropylene improves the intermolecular interactions, reduces the diffusion rate of volatile components within the material, and decreases VOCs emitted from the material. Ethylene-alkyl acrylate has high polarity and adsorption properties, and can react with some organic gases. The material exhibits adsorption properties; by adsorbing small molecule gases, ethylene-alkyl acrylate can reduce the overall VOC release of the material. The outer layer 4 of polyetheretherketone material has a smooth surface, making it easy to clean and maintain, keeping the car interior hygienic while also reducing VOCs. The anti-slip texture 5 and anti-slip block 6 at the bottom of the mat 1 are made of nitrile rubber, which increases the friction at the bottom of the carpet and reduces carpet displacement. Nitrile rubber itself also has the advantage of strong wear resistance. Through the cooperation of the anti-slip texture 5 and anti-slip block 6 made of nitrile rubber, the friction at the bottom of the carpet is increased, and the carpet displacement is reduced, which can effectively keep the carpet in place and avoid affecting the driver's user experience.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
