[0035] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0037] The foamed interior decoration parts provided in the present application are used as the internal structure of vehicles, for example, air ducts, luggage racks, and other decorative panels. Vehicles include public transportation vehicles such as buses and rail trains. For example, in a bus, air duct structures are arranged on both sides of the top of the vehicle, and the air duct structures extend in the front-to-back direction to deliver cold air and warm air to the top of each seat. The foamed interior decoration parts provided in the present application include a covering layer, a foaming layer and a profile strip, which are directly made into an integrated structure through a foaming process. There is no need to connect the various parts, which effectively simplifies the assembly process and can be installed as a whole to the corresponding position inside the vehicle. The following is a detailed description with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the foamed interior component 100 includes a covering layer 10, a foamed layer 20 and a profile strip 30. The profile strip 30 is arranged on at least one side edge of the covering layer 10, the foamed layer 20 is located on the covering layer 10 and is combined with the covering layer 10, and the material of the foamed layer 20 is filled into the internal structural space of the profile strip 30 so that the foamed layer 20 is directly combined with the profile strip 30.

[0039] Specifically, the covering layer may be a metal plate, leather, fabric, etc. During foaming, the foaming material foams directly on the covering layer, and is combined with the covering layer after the foaming is completed.

[0040] In one embodiment, if Figure 2 and Figure 3 As shown, the cover layer 10 includes an upper cover layer 12 and a lower cover layer 11. The upper cover layer 12 is located on the upper side of the foam layer 20 and is combined with the foam layer 20 to serve as the upper structure of the foam interior. The lower cover layer 11 is located on the lower side of the foam layer 20 and is combined with the foam layer 20 to serve as the lower structure of the foam interior. Figure 1 As shown, the foam interior part is provided with a covering layer only on one side of the foam layer 20 .

[0041] In one embodiment, if Figure 3 As shown, the profile strip 30 includes a first profile strip 31 and a second profile strip 32; the first profile strip 31 and the second profile strip 32 extend in the same direction and are respectively located at the edge positions of both sides of the covering layer and the foaming layer 20. In another embodiment, as Figure 1 and Figure 2 As shown, the foamed interior part is provided with a profile strip only on one side edge of the cover layer.

[0042] refer to Fig.10 and Fig.11 The foamed interior component 100 is foamed using a foaming mold 40 composed of a lower mold 41 and an upper mold 42 .

[0043] refer to Figure 1In an exemplary structure, the foam interior decoration part 100 includes a cover layer 10 arranged at the bottom and a profile strip 30 located at the right position. When making the foam interior decoration part, a foaming mold composed of a lower mold and an upper mold is used for foaming. Specifically, the cover layer 10 is first placed on the surface of the lower mold, and there is a foaming cavity between the upper mold and the lower mold for molding the foaming material. The cover layer 10 is arranged on one side of the lower mold, located on the lower side of the foaming cavity, so that the foaming layer formed after foaming is located above the cover layer. The profile strip 30 is placed on the right side of the foaming cavity. After foaming, the profile strip is located at the edge of the foaming layer, forming the edge structure of the foam interior decoration part. During foaming, the foaming material is injected into the foaming cavity defined by the lower mold and the upper mold. As the foaming material undergoes a foaming reaction in the foaming cavity and fills the foaming cavity, the foaming material is combined with the cover layer 10 and the profile strip 30 to form an integrated structure.

[0044] refer to Figure 2 In an exemplary structure, the foam interior component 100 includes an upper covering layer 12 and a lower covering layer 11, and a profile strip 30 located on the right side. The upper covering layer 12 is located on the upper side of the foaming layer 20, the lower covering layer 11 is located on the upper side of the foaming layer 20, and the profile strip 30 is located on the right side of the foaming layer 20. When making the foam interior component, a foaming mold consisting of a lower mold and an upper mold is used for foaming. Specifically, the upper covering layer 12 is first placed on the surface of the lower mold, and the lower covering layer 11 is placed on the surface of the upper mold. There is a foaming cavity between the upper mold and the lower mold for molding the foaming material. The upper covering layer 12 and the lower covering layer 11 are respectively located on the upper and lower sides of the foaming cavity. The profile strip 30 is placed on the right side of the foaming cavity. After foaming, the profile strip is located at the edge of the foaming layer, forming the edge structure of the foam interior component. During foaming, the foaming material is injected into the foaming cavity defined by the lower mold and the upper mold. As the foaming material undergoes a foaming reaction in the foaming cavity and fills the foaming cavity, the foaming material is combined with the upper covering layer 12, the lower covering layer 11 and the profile strip 30 to form an integrated structure.

[0045] refer to Figure 3 In an exemplary structure, the foam interior component 100 includes an upper cover layer 12 and a lower cover layer 11, and profile strips 30 on both sides. The upper cover layer 12 is located on the upper side of the foam layer 20, the lower cover layer 11 is located on the upper side of the foam layer 20, and the profile strips 30 are located on both sides of the foam layer 20. Fig.10 and Fig.11, the foamed interior component 100 is foamed using a foaming mold 40 composed of a lower mold 41 and an upper mold 42. When making the foamed interior component, the foaming mold 40 composed of a lower mold 41 and an upper mold 42 is used for foaming. Specifically, firstly, the upper covering layer 12 is placed on the surface of the lower mold 41, and the lower covering layer 11 is placed on the surface of the upper mold 42. There is a foaming cavity between the upper mold 42 and the lower mold 41 for forming the foaming material. The upper covering layer 12 and the lower covering layer 11 are respectively located on the upper and lower sides of the foaming cavity. The profile strip 30 is placed on the left and right sides of the foaming cavity. After foaming, the profile strips on both sides are located at the edge of the foaming layer, forming the edge structure of the foamed interior component. During foaming, the foaming material is injected into the foaming cavity defined by the lower mold and the upper mold. As the foaming material undergoes a foaming reaction in the foaming cavity and fills the foaming cavity, the foaming material is combined with the upper covering layer 12 and the lower covering layer 11 and the profile strips 30 on both sides to form an integrated structure.

[0046] In one embodiment, at least one of the upper cover layer 12 and the lower cover layer 11 is configured as a leather layer. Figure 1-Figure 3 As shown, the cover layer 10 is a leather layer.

[0047] like Figure 3 As shown, the present application provides a foam interior decoration component, which includes a profile strip, an upper leather layer, a lower leather layer, and a foam layer. Among them, the profile strip is arranged along the length extension direction, the upper leather layer is used to constitute the upper structure of the luggage rack, and the lower leather layer is used to constitute the lower structure of the luggage rack, and the foam layer is filled in the internal space enclosed by the upper leather layer, the lower leather layer, and the profile strips at the edge positions on both sides. At the edge positions on both sides of the foam interior decoration component, the material of the foam layer fills the internal structural space of the profile strip, so that the foam layer is directly combined with the profile strip to form a connection relationship. The upper leather layer covers the upper part of the foam layer between the profile strips on both sides, and the lower leather layer covers the lower part of the foam layer between the profile strips on both sides. Specifically, the upper leather layer is equivalent to the upper covering layer 12, and the lower leather layer is equivalent to the lower covering layer 11. Figure 3 The foamed interior component 100 is shown for further explanation.

[0048] Specifically, the main body of the foamed interior decoration part 100 is composed of a three-layer structure, namely, an upper leather layer, a lower leather layer, and a foaming layer in the middle. The upper leather layer and the lower leather layer are leather materials, and the leather materials can be leather, recycled leather, artificial leather, and synthetic leather, which are used to cover the upper and lower surfaces of the foamed interior decoration part. Among them, the leather can be cowhide, sheepskin and pigskin. Recycled leather is made by crushing the waste skins and leather scraps of various animals and mixing chemical raw materials for processing. Artificial leather is also called imitation leather or rubber material, which is a general term for artificial materials such as PVC and PU. It is made by foaming or laminating PVC and PU of various different formulations on a textile base or a non-woven base. Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute material for it. In addition, the foaming layer is made of foaming material through a foaming molding process. In the foaming molding process or the foaming polymer material, a honeycomb or porous structure is formed by adding and reacting a physical foaming agent or a chemical foaming agent.

[0049] refer to Fig.10 and Fig.11 The foaming interior part 100 is foamed using a foaming mold 40 composed of a lower mold 41 and an upper mold 42. When making the foaming interior part, first, the upper leather layer is laid on the surface of the upper mold 41, and the lower leather layer is placed on the surface of the lower mold 42. There is a foaming cavity between the upper mold and the lower mold for forming the foaming material. Here, the upper leather layer and the lower leather layer are placed on the upper and lower sides of the foaming cavity, and the foaming layer formed after foaming is directly combined with the leather layers on the upper and lower sides. Next, the profile strip is placed at the predetermined positions on both sides of the foaming cavity defined by the upper mold and the lower mold, and the profile strip is located at the edge positions on both sides of the foaming interior part to form the edge structure of the foaming interior part. Next, the foaming material is injected into the foaming cavity for foaming reaction, so that the foaming material fills the space between the upper leather layer and the lower leather layer, and expands to both sides to fill the internal structure space of the profile strips on both sides, so that the foaming layer is directly combined with the profile strip to form a connection relationship, so as to make the foaming interior part. After foaming, the foaming material fills the foaming cavity between the upper leather layer and the lower leather layer, so that the upper leather layer and the lower leather layer, the profile strips on both sides, and the foaming material form an integral structure, namely the foamed interior component. Finally, the foamed interior component is installed as a whole in the vehicle interior space.

[0050] It should be understood that in the manufacturing process of the above-mentioned foamed interior parts, the foaming material is filled into the foaming space formed by the upper leather layer, the lower leather layer, and the profile strips on both sides through the foaming process, so that an integrated foamed interior part can be formed. Therefore, the main structure of the foamed interior part is formed by combining the upper leather layer, the lower leather layer, the foaming layer, and the profile strip through the foaming process, which is an integrated structure. During assembly, it is only necessary to fix the integrated structure to the vehicle interior structure, which effectively simplifies the assembly process. In addition, the upper leather layer, the lower leather layer, the foaming layer, and the profile strip are more tightly combined, and compared with the structure that uses connectors to connect and fix multiple components, the connection gap is eliminated. Therefore, the foamed interior part provided by the present application is more stable and is not prone to abnormal noise in the vehicle.

[0051] In addition, it should be noted that the profile strip is a section of profile. The profile is an object with a certain geometric shape made of iron or steel or a material with a certain strength and toughness through rolling, extrusion, casting and other processes. This type of material has a certain appearance size, a certain cross-section shape, and certain mechanical and physical properties. In the embodiment of the present application, the profile strip has a complex cross-sectional shape. The complex cross-sectional profile is also called a special-shaped cross-sectional profile, which is characterized in that the cross-section has obvious convex and concave branches. The profile strip composed of the complex cross-sectional profile has a complex internal space, which can be used to fill the foaming material during foaming, and is convenient for combining with the foaming layer. The typical profile is an aluminum profile. In the present application, the profile strip can be set as an aluminum profile. If Figure 3 As shown, the profile strip includes a first profile strip 31 on the left and a second profile strip 32 on the right.

[0052] The present application also provides a vehicle luggage rack, comprising the above-mentioned foam interior decoration part 100. Figure 4 As shown, the foamed interior trim 100 is used as the bottom plate of the independent luggage rack. Figure 6 and Figure 7 In the luggage rack and air duct structure shown, the foamed interior component 100 is used as the bottom plate of the luggage rack.

[0053] The present application also provides a vehicle air duct structure, including the above-mentioned foam interior decoration part 100. Figure 5 and Figure 8 As shown, the foamed interior component 100 is used as an air duct structure. Figure 5 The structure shown only contains an independent duct structure. Figure 8 The structure shown includes a luggage rack and an air duct structure.

[0054] also, Fig. 9 A vehicle interior decoration panel made of a foamed interior decoration member 100 is shown, which is used as a vehicle interior covering member.

[0055] The present application also provides a means of transportation, including the foamed interior parts provided in the previous part. The means of transportation include public transportation such as buses and rail trains. For example, in a bus, air duct structures are arranged on both sides of the top of the vehicle, and the air duct structures extend in the front-to-back direction to deliver cold air and warm air to the top of each seat. The foamed interior parts provided in the present application include a covering layer, a foaming layer and a profile strip, which are directly made into an integrated structure through a foaming process. There is no need to connect the various parts, which effectively simplifies the assembly process and can be installed as a whole to the corresponding position inside the vehicle.
