[0002] Traditional methods for decorating vehicle parts (such as the front of a vehicle) often use direct processing of metal or plastic parts (including but not limited to directly coating metal or plastic as the material). The disadvantages of this method are: limited design flexibility and high difficulty in forming complex patterns. Utility Model Content

[0003] The problem solved by the utility model is that the flexibility of the decorative design on vehicle parts is limited and it is difficult to form complex patterns.

[0004] In order to solve the above problems, the utility model provides a decorative film and a vehicle decoration having the decorative film.

[0005] In a first aspect, the utility model provides a decorative film for connecting with a material, wherein the decorative film comprises a decorative pattern layer and a film layer arranged in sequence;

[0006] The side of the decorative pattern layer away from the film layer is used for adhesion to the material, or the side of the film layer away from the decorative pattern layer is used for adhesion to the material.

[0007] Optionally, the decorative film further includes an adhesive layer; when the side of the film layer away from the decorative pattern layer is used to connect with the material, the adhesive layer is located on the side of the film layer away from the decorative pattern layer, for adhering the film layer to the material.

[0008] Optionally, the decorative film further includes a protective layer, and the protective layer is located between the film layer and the decorative pattern layer.

[0009] Optionally, the decorative film is used to be located on the outside of the material; the decorative pattern layer, the protective layer, the film layer and the adhesive layer are stacked in sequence from the outside to the inside.

[0010] Optionally, the decorative film further includes a light-transmitting protective layer, which is located on the side of the decorative pattern layer away from the film layer; the decorative film is used to be located on the outside of the material; the protective layer, the decorative pattern layer, the film layer and the adhesive layer are stacked in sequence from the outside to the inside.

[0011] Optionally, the decorative film further includes an adhesive layer. When the side of the decorative pattern layer away from the film layer is used to connect with the material, the adhesive layer is located on the side of the decorative pattern layer away from the film layer, and the adhesive layer is used to adhere the decorative pattern layer to the material.

[0012] Optionally, the decorative film is used to be arranged on the outside of the material; the decorative film also includes a protective layer, and the decorative film includes the adhesive layer, the decorative pattern layer, the film layer and the protective layer arranged in sequence from the inside to the outside; the film layer and the protective layer are configured to be light-transmissive.

[0013] In a second aspect, the present invention provides a vehicle trim, comprising a material, a protective layer, and a decorative film;

[0014] The decorative film is located on the inner side of the material, and the protective layer is located on the outer side of the material; the decorative film includes the decorative pattern layer, the film layer and the adhesive layer arranged in sequence from the inside to the outside; the protective layer, the material, the adhesive layer and the film layer are configured to be light-transmissive.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0028] The term "including" and its variations used in this document are open inclusions, that is, "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optionally" means "optional embodiments". The relevant definitions of other terms will be given in the following description. It should be noted that the concepts of "first", "second", etc. mentioned in this utility model are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0029] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0030] It should be noted that, in this utility model Figures 2 to 6 The direction indicated by the arrow in the middle is from the inside to the outside, and from the outside to the inside is generally the direction of the viewer's line of sight when looking at the vehicle trim.

[0031] In the present invention, if a component is described as "translucent" or "made of translucent material", the component has a certain degree of transparency, specifically, it can be translucent or fully transparent. The present invention provides a vehicle trim, including a vehicle component and Figure 1 A decorative film 1 is shown, which is used to connect to a vehicle component such as the front face of a vehicle, and includes a decorative pattern layer 11 and a film layer 12 arranged in sequence; the side of the decorative pattern layer 11 away from the film layer 12 is used to adhere to the vehicle component, or the side of the film layer 12 away from the decorative pattern layer 11 is used to adhere to the vehicle component.

[0032] Furthermore, the decorative film 1 provided by the present invention is particularly suitable for decoration on vehicle parts through the TOM (Three dimension Overlay Method, 3D surface decoration) process. For example, the vehicle part is the front face of the vehicle, and the decorative film is decorated on the front face of the vehicle to form a vehicle exterior part of the front face assembly.

[0033] As can be understood from the above, the use of the decorative film provided by the present invention as a vehicle component decoration differs from the traditional vehicle component method of "often directly processing and forming metal or plastic parts." Because the decorative film and vehicle component are processed and formed separately, the decorative film has greater design flexibility and can be assembled to form a vehicle decoration with more flexible appearance design. In particular, because the decorative film and vehicle component are processed and formed separately, when complex patterns need to be formed on the vehicle component for decoration, the decorative film provided by the present invention can easily form such patterns through mature and cost-effective printing technology.

[0034] It is understandable that the aforementioned vehicle parts can be any area or part on the vehicle to be decorated. For ease of description, the aforementioned "vehicle parts" will be collectively referred to as materials below.

[0035] In the present invention, the material can optionally be placed on the side of the decorative pattern layer 11 away from the film layer 12, or on the side of the film layer 12 away from the decorative pattern layer 11. When the side of the decorative pattern layer 11 away from the film layer 12 is used to adhere the material, the film layer 12 and / or the material can be made of a light-transmitting material, so that the color, pattern, and texture of the decorative pattern layer 11 can be displayed. At the same time, by changing the light transmittance and color of the film layer 12 or the material, the decorative pattern layer 11 can present a special visual effect. The film layer 12 and the material can also protect the pattern of the decorative pattern layer 11 from external factors such as scratches and ultraviolet radiation. When the side of the film layer 12 away from the decorative pattern layer 11 is used to adhere the material, the light transmittance, thickness, and other physical properties of the film layer 12 can be prevented from affecting the pattern display effect of the decorative pattern layer 11, thereby allowing the decorative pattern layer 11 to display the best pattern effect.

[0036] For example, the TOM process parameters may be: heating temperature of 80° C.-200° C., heating time of 5s-300s, pressure of 90kPa-400kPa, and holding time of 1s-60s.

[0037] The material can be made of PC (Polycarbonate), PMMA (Polymethyl methacrylate), PP (Polypropylene), ABS (Acrylonitrile Butadiene Styrene), AES (Acrylonitrile Ethylene Styrene), etc., either alone or in combination, and is manufactured using an injection molding process with a thickness of 1mm-5mm.

[0038] The decorative pattern layer 11 can be printed and can include multiple or single layers of ink patterns or colors. The thickness of the decorative pattern layer 11 can range from 1 μm to 60 μm, and the curing method can be thermal curing at a temperature of 50°C to 145°C for a curing time of 10 minutes to 180 minutes.

[0039] The membrane layer 12 can be one of PC film, PMMA film, PC+PMMA composite film or PET (Polyethylene Terephthalate) film, etc. The membrane layer 12 can be colorless or colored (such as smoked color, blue), and the specific color is selected according to the needs.

[0040] Illustratively, the thickness of the diaphragm layer 12 ranges from 0.01 mm to 0.5 mm, such as 0.01 mm, 0.05 mm, 0.075 mm, 0.1 mm, 0.125 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.5 mm, etc.

[0041] In the present invention, the decorative pattern layer 11 and the membrane layer 12 of the decorative membrane 1 are arranged in sequence, and the membrane layer 12 is used as a carrier to carry the decorative pattern layer 11 .

[0042] Regarding the above-mentioned vehicle trim, the following are more detailed embodiments:

[0043] Example 1

[0044] like Figure 2 As shown, in addition to the aforementioned film layer 12 and decorative pattern layer 11, the decorative film 1 provided in this embodiment also includes an adhesive layer 13 and a protective layer 14. The film layer 12 also serves as a carrier for the adhesive layer 13 and the protective layer 14, and the decorative film 1 is adhered to the material 2 via the adhesive layer 13. From the outside to the inside, the decorative film 1 includes the decorative pattern layer 11, the protective layer 14, the film layer 12, and the adhesive layer 13, which are stacked in this order. In this embodiment, the adhesive layer 13 is located on the side of the film layer 12 away from the decorative pattern layer 11. The side of the film layer 12 away from the decorative pattern layer 11 is adhered to the material 2 via the adhesive layer 13.

[0045] It can be understood that since the protective layer 14, the membrane layer 12, the adhesive layer 13 and the material 2 are arranged on the inner side of the decorative pattern 11, the protective layer 14, the membrane layer 12, the adhesive layer 13 and the material 2 can be set to be light-transmissive or opaque (or called light-proof) according to the specific needs of technical personnel in this field.

[0046] As mentioned above, the adhesive layer 13 can be formed on the film layer 12 by printing, coating, or the like, or can be formed on the substrate 2 by spraying. The thickness of the adhesive layer 13 can range from 0.1 μm to 60 μm. As can be understood, the adhesive layer 13 firmly adheres the film layer 12 to the substrate 2, ensuring the stability and durability of the multi-layer structure. Furthermore, the presence of the adhesive layer 13 allows the decorative film 1 to be easily attached to the substrate 2 without the need for additional adhesives or complex fixing steps, thereby improving the efficiency of the assembly process.

[0047] It should be noted that in each embodiment of the present invention, the adhesive layer 13 has the above-mentioned beneficial effects and can be formed by the above-mentioned preferred thickness range and printing, coating, spraying, etc. For the sake of simplicity, they will not be described one by one below.

[0048] Based on the above, in this embodiment, the aforementioned protective layer 14 can be made by printing or coating. Exemplarily, the thickness of the protective layer 14 can range from 1μm to 40μm (for example, 1μm, 2μm, 4μm, 10μm, 20μm, 32μm, 38μm, 40μm). The curing method of the protective layer 14 can be UV (Ultraviolet) curing or thermal curing. If the curing method of the protective layer 14 is UV curing, either UV semi-curing type or UV full curing type can be selected. When the protective layer 14 is UV semi-curing type, the first curing is performed after coating, and the second curing is performed after the decorative film 1 is decorated on the material 2. When the protective layer 14 is thermally cured, the curing temperature can be 60℃-130℃, and the curing time can be 10min-180min, and curing is performed after coating.

[0049] It can be understood that the addition of the protective layer 14 improves the overall mechanical strength and durability of the decorative film 1 .

[0050] As mentioned above, the protective layer 14 of this embodiment is also a transparent colorless coating. Based on this, it should be further explained that the inventors of this case have found that, due to the limitations of light transmittance or slight refraction effects, even if the protective layer 14 is made of transparent materials, its presence will still affect the pattern presentation effect of the decorative pattern layer 11; when the design of the protective layer 14 located outside the decorative pattern layer 11 as described in this embodiment is adopted, the decorative pattern layer 11 is directly exposed to the outside (i.e., not blocked by other materials) to ensure that the color and details of the pattern can be retained to the maximum extent, enhance the visual effect of the pattern, make the decorative film present a clearer pattern effect, achieve diversified decoration, and meet the personalized needs of some customers. Based on this, when the decorative pattern layer 11 has a special texture or texture, the design of the decorative pattern layer 11 being directly exposed to the outside can especially provide a more realistic tactile experience to the user.

[0051] Furthermore, the decorative pattern layer 11 of this embodiment is preferably a pattern layer and / or color layer made of weather-resistant exterior decorative ink (in other words, the decorative pattern layer 11 of this embodiment includes weather-resistant ink for forming patterns or colors), so as to effectively resist the influence of external environmental factors such as sunlight, rain and temperature changes, thereby improving durability.

[0052] Thus, because the pattern or color on the decorative pattern layer 11 is formed by weather-resistant exterior ink, the design of arranging the decorative pattern layer 11 on the protective layer 14 in this embodiment also has the following advantages: under the premise that the protective layer 14 covers the diaphragm layer 12, when the decorative pattern layer 11 is a hollow pattern, the hollow portion of the hollow pattern will naturally be protected by the protective layer 14 to protect the portion of the diaphragm layer 12 located below the protective layer 14. That is, based on the pattern portion of the decorative pattern layer 11 being drawn with weather-resistant exterior ink, both the pattern portion and the diaphragm layer 12 portion can be protected. The decorative diaphragm 1 can effectively resist the influence of external environmental factors (such as scratches, wear, sunlight, rain, temperature changes and corrosion, etc.), effectively preventing external factors from causing direct damage to the diaphragm layer 12 exposed by the hollow portion of the decorative pattern layer 11, thereby improving durability.

[0053] Furthermore, the vehicle trim provided by this embodiment has the following advantages: the multi-layer structure design can make the presented pattern effect more prominent and rich, thereby enhancing the overall aesthetics of the vehicle trim; when other parts (such as the membrane layer 12) located below the decorative pattern layer 11 are made of colored materials, these other parts can also interact with the decorative pattern layer 11 and other layers to create a richer, more coordinated, or layered visual effect. It can be understood that in each embodiment of the present invention, as long as the vehicle trim has a multi-layer structure, the vehicle trim will have the advantages of the multi-layer structure described above, as well as the interactions between the multi-layer structures. For the sake of brevity, these advantages will not be described in detail below.

[0054] Example 2

[0055] like Figure 3 As shown, this embodiment provides a vehicle trim that is basically designed the same as that of the first embodiment; the difference between this embodiment and the first embodiment is that, compared with the first embodiment, the positions of the protective layer 14 and the decorative pattern layer 11 in this embodiment are reversed.

[0056] Specifically, the decorative film 1 of this embodiment includes four parts stacked in sequence, from the outside to the inside: a protective layer 14, a decorative pattern layer 11, a film layer 12 and an adhesive layer 13; the decorative film 1 is arranged on the outside of the material 2 and is connected to the material 2 through the adhesive layer 13.

[0057] It is understood that the presence of the protective layer 14 increases the overall structural strength and durability of the decorative film 1. The design of the protective layer 14 being located on the outermost side can effectively protect other parts of the decorative film 1 and the material 2.

[0058] It is understood that in this embodiment, a light-transmissive protective layer 14 is used to maintain the clarity of the decorative pattern layer 11 and ensure that the decorative pattern layer 11 is clearly visible. Furthermore, when those skilled in the art use protective layers 14 with different light transmittances and colors, the protective layer 14 can synergize with the decorative pattern layer 11, allowing the decorative pattern layer 11 to present different pattern effects.

[0059] It is understandable that in this embodiment, when the decorative pattern layer 11 is located on the inner side of the protective layer 14, and the decorative pattern layer 11 adopts a combination of multiple pattern layers and / or multiple color layers, it can give the vehicle accessories a rich visual effect. It is also understandable that the aforementioned visual effect is different from the visual effect presented in Example 1 (when the decorative pattern layer 11 is located on the outer side of the protective layer 14). Specifically, the inventors of this case found that when the decorative pattern layer 11 is located on the outer side of the protective layer 14, the brightness of the decorative pattern layer 11 is different compared to the case where the decorative pattern layer 11 is located on the inner side of the protective layer 14. It is understandable that based on this brightness difference, designers can be guided to provide more diverse appearances for vehicle accessories according to user needs.

[0060] It can be understood that since the membrane layer 12, the adhesive layer 13 and the material 2 are arranged on the inner side of the decorative pattern 11, the membrane layer 12, the adhesive layer 13 and the material 2 can be set to be translucent or opaque (or called opaque) according to the specific needs of technical personnel in this field.

[0061] Example 3

[0062] This embodiment provides a vehicle trim that is substantially the same in design as that of the second embodiment or the first embodiment. The difference between this embodiment and the second embodiment or the first embodiment is that the design of the protective layer 14 is eliminated.

[0063] Example 4

[0064] like Figure 4 As shown, this embodiment provides a vehicle trim having a partially identical design to that of the third embodiment; the similarities between this embodiment and the third embodiment include: the decorative pattern layer 11 and the membrane layer 12 are disposed adjacent to each other. The differences between this embodiment and the third embodiment include: the decorative membrane 1 includes a decorative pattern layer 11, a membrane layer 12, and an adhesive layer 13 stacked sequentially from the inside to the outside, and the vehicle trim also includes a light-transmissive protective layer 14, the protective layer 14 being located on the side of the adhesive layer 13 away from the membrane layer 12, the side of the adhesive layer 13 away from the membrane layer 12 and the side of the protective layer 14 close to the adhesive layer 13 being respectively used to connect the two sides of the material 2, the material 2 being disposed between the adhesive layer 13 and the protective layer 14, and the material 2, the adhesive layer 13, and the membrane layer 12 are all designed to be light-transmissive.

[0065] In this embodiment, the protective layer 14 can be formed on the substrate 2 by spraying, curtain coating, printing, TOM film lamination, or PUR (polyurethane), and the thickness can range from 1 μm to 700 μm (e.g., 1 μm, 10 μm, 30 μm, 70 μm, 150 μm, 310 μm, 630 μm, 700 μm). Depending on product requirements, the protective layer 14 can be retained or omitted. The protective layer 14 can be cured by UV or thermal curing: the film thickness is preferably 3 μm to 30 μm for UV curing and 3 μm to 40 μm for thermal curing.

[0066] It can be understood that the protective layer 14 is located on the outside of the material 2 and is also the outermost part of the vehicle trim, which can reduce direct damage to the material 2 caused by external factors and extend the service life of the material 2; the protective layer 14 and the material 2 are located on the outside of the decorative film 1, which can maximize the protection of the decorative film 1 and indirectly extend the service life of the decorative film 1; at the same time, the translucent protective layer 14 maintains the original appearance of the material 2, ensures the clarity and aesthetics of the material 2, and can also provide additional texture, such as gloss or matte effects, to enhance the overall visual experience of the vehicle trim.

[0067] It can also be understood that since the material 2 , the adhesive layer 13 and the film layer 12 are all made of light-transmitting materials, and the protective layer 14 is also light-transmitting, this embodiment can effectively display the color, pattern or texture of the decorative pattern layer 11 .

[0068] In addition, based on the fact that the material 2 is located on the inner side of the protective layer 14 and the outer side of the decorative film 1, that is, multiple layers of light-transmitting material are provided on the outer side of the decorative pattern 11, the inventors of this case have found that the vehicle trim provided in this embodiment can form a low-brightness effect similar to crystal at a lower cost; there is no doubt that this helps to provide a diverse appearance of vehicle trims to meet the personalized needs of customers.

[0069] Furthermore, in this embodiment, the design of the membrane layer 12 being located outside the decorative pattern layer 11 can also enhance the layering and depth of the pattern, making the decorative pattern layer 11 more three-dimensional and vivid, while providing additional protection for the decorative pattern layer 11 and improving the overall structural strength of the decorative membrane 1.

[0070] Example 5

[0071] like Figure 5 As shown, this embodiment provides a vehicle trim that is partially identical in design to the fourth embodiment; the similarities between this embodiment and the fourth embodiment include: the decorative film 1 includes a decorative pattern layer 11 and a film layer 12, the decorative pattern layer 11 and the film layer 12 are adjacently arranged, and the film layer 12 adopts a light-transmitting design.

[0072] The differences between this embodiment and the fourth embodiment include: the decorative film 1 further includes an adhesive layer 13. The decorative film 1 is connected to the outside of the substrate 2, specifically via the adhesive layer 13. Specifically, the side of the decorative pattern layer 11 facing away from the film layer 12 is connected to the substrate 2 via the adhesive layer 13. More specifically, in the decorative film 1, the film layer 12, the decorative pattern layer 11, and the adhesive layer 13 are arranged in order from the outside to the inside.

[0073] In addition, the vehicle trim provided in this embodiment is basically the same in design as that in the second embodiment. The difference between this embodiment and the second embodiment is that, compared with the second embodiment, the positions of the diaphragm layer 12 and the decorative pattern layer 11 in this embodiment are reversed.

[0074] Optionally, the decorative film 1 further includes a light-transmissive protective layer 14, which is located on the side of the film layer 12 away from the decorative pattern layer 11. When the protective layer 14 is provided, the decorative film 1 comprises four sequentially stacked parts, namely, from the outside to the inside: the protective layer 14, the film layer 12, the decorative pattern layer 11, and the adhesive layer 13.

[0075] Understandably, since the adhesive layer 13 and the material 2 are positioned inside the decorative pattern 11, they can be configured to be light-transmissive or opaque, depending on the specific needs of those skilled in the art. Since the membrane layer 12 is made of a light-transmissive material, and the protective layer 14 is also light-transmissive, the design of this embodiment ensures that the protective layer 14, the membrane layer 12, and the decorative pattern layer 11 work together to effectively display the color, pattern, or texture of the decorative pattern layer 11. Using a protective layer 14 with varying gloss or matte finishes can also create unique visual effects on the vehicle exterior.

[0076] Exemplarily, similar to the first embodiment, the protective layer 14 can be made by printing or coating; the thickness of the protective layer 14 can range from 1 μm to 40 μm (for example, 1 μm, 2 μm, 4 μm, 10 μm, 20 μm, 32 μm, 38 μm, 40 μm).

[0077] For example, similar to Example 1 or Example 2, the protective layer 14 can be cured by UV or thermal curing. If the protective layer 14 is cured by UV, either a UV semi-curing method or a UV full-curing method can be selected. When the protective layer 14 is a UV semi-curing method, the primary curing is performed after coating, and the secondary curing is performed after the decorative film 1 is decorated on the material 2. When the protective layer 14 is thermally cured, the curing temperature is 60°C-130°C, and the curing time is 10 minutes-180 minutes. Curing is performed after coating.

[0078] As can be understood, similar to the second embodiment, the protective layer 14 enhances the overall structural strength and durability of the decorative film 1. Positioned on the side of the film layer 12 away from the decorative pattern layer 11, the protective layer 14 effectively protects the decorative pattern layer 11 from external factors such as scratches and abrasion, thereby extending the service life of the decorative film 1 to a certain extent. Positioned on the outermost side, the protective layer 14 effectively prevents external factors from damaging the other layers, thereby preserving the clarity and color vividness of the pattern.

[0079] Furthermore, since the membrane layer 12 is located on the inner side of the protective layer 14 and the outer side of the decorative pattern layer 11 , the membrane layer 12 can also provide protection for the decorative pattern layer 11 .

[0080] Furthermore, when the membrane layer 12 is made of a colored material, it can also work together with the decorative pattern layer 11 and other layers to create a richer, more coordinated, or layered visual effect. The decorative pattern layer 11 is located inside the membrane layer 12, and through the design of patterns and colors, it can give the vehicle trim a rich visual effect.

[0081] Example 6

[0082] like Figure 6 As shown, this embodiment provides a vehicle trim having a partially identical design to that of the fourth embodiment; the differences between this embodiment and the fourth embodiment include: compared with the fourth embodiment, the positions of the diaphragm layer 12 and the decorative pattern layer 11 in this embodiment are reversed.

[0083] Specifically, the structure of the decorative film 1 of this embodiment includes a back adhesive layer 13, a decorative pattern layer 11 and a film layer 12 stacked in sequence from the outside to the inside; the vehicle trim also includes a light-transmissive protective layer 14, which is located on the side of the back adhesive layer 13 away from the decorative pattern layer 11. The side of the back adhesive layer 13 away from the decorative pattern layer 11 and the side of the protective layer 14 close to the back adhesive layer 13 are respectively used to connect the two sides of the material 2, and the material 2 is located between the protective layer 14 and the back adhesive layer 13.

[0084] As mentioned above, in this embodiment, the base material 2 and the adhesive layer 13 are both made of a light-transmitting material. It is also understandable that, because the membrane layer 12 is disposed inside the decorative pattern 11, the membrane layer 12 can be configured to be light-transmitting or opaque (or light-proof) according to the specific needs of those skilled in the art.

[0085] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
