Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0037] While existing silica-containing crystal decorative pieces possess excellent physical properties such as transparency and strong luster, their manufacturing process is limited. In particular, it is difficult to achieve large-area concave texture structures using conventional cutting techniques, and hot-melt pressing reduces transparency, affecting the overall appearance. Furthermore, these crystal decorative pieces exhibit a relatively fixed reflection angle under light, preventing them from producing a dazzling effect.

[0038] Please refer to Figures 1-6 The embodiments of this application provide a decorative part 10, including a first crystal 100 mainly made of silicon dioxide, and a second crystal 200 made of plastic. The second crystal 200 has a first surface 210 and a second surface 220 opposite to each other. The first surface 210 is connected to the first crystal 100, and the second surface 220 is provided with a textured structure 300.

[0039] It should be noted that the first crystal 100 is an existing silicon dioxide-containing crystal, such as K9 or K5 material. K9 is a common optical glass whose main component is silicon dioxide. It has a low dispersion coefficient and high light transmittance and is usually used to make precision optical components such as prisms, lenses, and filters. K5 is also a common optical glass with a similar composition to K9, but the proportion of oxides is slightly different, resulting in certain differences in its physical and optical parameters. For example, the refractive index of K5 glass is slightly lower than that of K9. Of course, both K9 and K5 materials have good light transmittance and can maintain consistent optical performance over a wide temperature range, making them suitable for decorative structures that require long-term stable use.

[0040] The first crystal 100, as the upper structure, retains the excellent transparency and luster of the silica-containing crystal. The second crystal 200 is made of plastic material such as PC or PMMA that is easy to injection mold or mold. The second surface 220 of the second crystal 200, as the surface away from the first crystal 100, has a textured structure 300 to change the reflection path of light inside the decorative part 10, thereby enhancing the overall brilliance of the decorative part 10.

[0041] The composite structure of the first crystal 100 and the second crystal 200 is based on the optimization of the light propagation path. By combining the first crystal 100 with the second crystal 200, which can be molded into a complex concave-convex structure, and setting the texture structure 300 on the second surface 220, the incident light a from the external light source (such as natural light or LED light) enters the decorative part 10 from the top surface or side surface of the first crystal 100 or the side surface of the second crystal 200, and is reflected at different angles when it reaches the texture structure 300. Finally, the outgoing light b is emitted from the top surface of the first crystal 100, thereby producing a rich light effect.

[0042] By introducing a second crystal 200 made of plastic material with a textured structure 300, combined with a first crystal 100 mainly made of silicon dioxide, the problem of silicon dioxide crystals being difficult to process with complex textures and lacking brilliance is solved, ultimately achieving a decorative effect that combines transparency, luster, and brilliance.

[0043] In some embodiments, the texture structure 300 includes a plurality of high portions and low portions, with a concave surface 310 formed between at least two adjacent high portions and low portions.

[0044] There is a certain angle difference or height difference between the high part and the low part. Due to the presence of the concave surface 310 formed between the high part and the low part, the light incident on the second surface 220 can be reflected at different angles on the concave surface 310, thereby significantly increasing the diversity of light propagation paths.

[0045] It should be noted that, for adjacent high and low parts, the thickness of the second crystal 200 in the high part is greater than the average thickness of the second crystal 200, and the thickness of the second crystal 200 in the low part is less than the average thickness of the second crystal 200; the shape of the concave surface 310 can be a plane, an arc surface or other regular or irregular curved surface, and there is no limitation on this.

[0046] By defining the texture structure 300 of the second surface 220 as multiple high and low parts, when an external light source (such as LED light or natural light) shines on the surface of the decorative piece 10, most of the light first enters the first crystal 100 and continues to propagate downwards to the second surface 220 of the second crystal 200 through its good transparency. During this process, the light will be reflected at different angles on different concave surfaces 310, and the light entering the groove will also undergo multiple back-and-forth reflections, resulting in the direction of the refracted light emitted from the surface of the first crystal 100 having stronger randomness and dispersion, ultimately forming a more dazzling and layered optical effect.

[0047] In some embodiments, the texture structure 300 includes a plurality of serrated structures 320 arranged sequentially.

[0048] The serrated structure 320 refers to a structure with obvious angular features. Each serrated structure 320 is composed of at least two tooth surfaces. Multiple serrated structures 320 are sequentially arranged on the second surface 220 to form a periodic surface undulation structure. Optionally, the second surface 220 is inclined relative to the first surface 210, and multiple serrated structures 320 are sequentially arranged along the inclined direction of the second surface 220.

[0049] It should be noted that the serrated structure 320 here is not limited to the traditionally symmetrical "V" shape, but refers to any similar shape with obvious turning points that can form a reflective interface. For example, the serrated structure 320 can be asymmetrical.

[0050] By defining the texture structure 300 of the second surface 220 as a plurality of sequentially arranged sawtooth structures 320, the diversity of the refraction and reflection paths of incident light within the decorative element 10 is effectively enhanced. When an external light source shines on the surface of the decorative element 10, most of the light enters the first crystal 100 and continues to propagate downwards to the second surface 220 of the second crystal 200. At this time, the light is reflected on different tooth surfaces of each sawtooth structure 320, and different directions of outgoing light are generated due to the different orientations of the tooth surfaces, thus presenting a richer, more dynamic and dazzling visual effect on the decorative element 10.

[0051] In an optional embodiment, the serrated structure 320 includes a first tooth surface 321 and a second tooth surface 322 connected to each other. The included angle between the first tooth surface 321 and the second surface 220 is greater than the included angle between the second tooth surface 322 and the second surface 220. In the arrangement direction of the plurality of serrated structures 320, one end of the second tooth surface 322 of the serrated structure 320 is connected to the top end of its own first tooth surface 321, and the other end of the second tooth surface 322 of the serrated structure 320 is connected to the bottom end of the first tooth surface 321 of the adjacent serrated structure 320.

[0052] The angle between the first tooth surface 321 and the second surface 220 is greater than the angle between the second tooth surface 322 and the second surface 220, indicating that the first tooth surface 321 and the second tooth surface 322 extending upward from the second surface 220 exhibit an asymmetrical structure. This angular difference design causes light to reflect in different directions on the first tooth surface 321 and the second tooth surface 322, thereby helping to achieve more complex optical effects and enhancing the visual performance of the decorative part 10.

[0053] In the arrangement direction of the multiple serrated structures 320, one end of the second tooth surface 322 of the serrated structure 320 is connected to the top end of its own first tooth surface 321, while the other end of the second tooth surface 322 is connected to the bottom end of the first tooth surface 321 of the adjacent serrated structure 320. This design creates a geometric shape with continuous transition between the serrated structures 320, which not only improves the stability of the overall structure but also reduces the difficulty of injection molding or compression molding.

[0054] Multiple serrated structures 320 constitute a continuous and regular textured structure 300. When illuminated by an external light source, this textured structure 300 enables light to undergo multi-level reflections between the multiple serrated structures 320, thereby producing richer optical effects.

[0055] In some embodiments, the texture structure 300 includes a plurality of wave-shaped structures 330 arranged sequentially.

[0056] Multiple wave-shaped structures 330 are arranged sequentially, forming an alternating pattern of crests and troughs in an approximately arc-shaped manner. When the second crystal 200 is roughly rectangular, the arrangement of the wave-shaped structures 330 can be along the length or width of the second crystal 200. Each wave-shaped structure 330 is a raised structure, and a depression is formed between adjacent wave-shaped structures 330, thus creating a regular and continuous undulating structure on the second surface 220, thereby reducing the difficulty of injection molding or compression molding.

[0057] By defining the texture structure 300 of the second surface 220 as a plurality of sequentially arranged wave-shaped structures 330, when an external light source shines on the surface of the decorative element 10, most of the light enters the first crystal 100 and continues to propagate downwards to the second surface 220 of the second crystal 200, where it is subsequently reflected at various locations on the surface of the wave-shaped structures 330. Because the wave-shaped structures 330 have continuously varying curvature and tilt angles, the reflected light at different locations is guided to different exit directions, thus producing a rich visual effect.

[0058] In an optional embodiment, the wave-shaped structure 330 has a first end and a second end opposite to each other, wherein the end face area of ​​the first end of the wave-shaped structure 330 is less than or equal to the end face area of ​​the second end.

[0059] Each wave-shaped structure 330 has two ends defined as a first end and a second end, respectively. The first end has a smaller end face area, while the second end can have a larger end face area. This difference in end face area design results in the wave-shaped structure 330 having a certain degree of inclination. Light rays reflected at different positions on the wave-shaped structure 330 will propagate along paths with different angles. Of course, in some embodiments, the end face area of ​​the first end of the wave-shaped structure 330 can also be equal to the end face area of ​​the second end.

[0060] Optionally, the first end of the wave-shaped structure 330 is located on the same side as the second end of another adjacent wave-shaped structure 330.

[0061] When multiple wave-shaped structures 330 are arranged sequentially, the first end of one wave-shaped structure 330 is on the same side as the second end of the adjacent wave-shaped structure 330. That is, the structural transition between two adjacent wave-shaped structures 330 is achieved by a similar staggered arrangement. This structural layout allows light to form a more complex angular distribution when it is reflected on the surface of multiple wave-shaped structures 330.

[0062] In some embodiments, the first crystal 100 and the second crystal 200 are stacked.

[0063] The stacking of the first crystal 100 and the second crystal 200 means that the thickness direction of the first crystal 100 and the second crystal 200 is consistent, and the first crystal 100 and the second crystal 200 are arranged in space along this thickness direction, maintaining a direct or indirect contact relationship. This design not only enhances the overall three-dimensionality and layering of the decorative part 10, but also brings differentiated optical performance through the combination of crystals of different materials. Optionally, the outer surfaces of the first crystal 100 and the second crystal 200 are flush, resulting in a high degree of flatness in the overall appearance of the decorative part 10.

[0064] For example, when both the first crystal 100 and the second crystal 200 are generally sheet-like, the thickness directions of the first crystal 100 and the second crystal 200 are consistent, and the first crystal 100 and the second crystal 200 are stacked along the thickness direction, so that the decorative part 10 has a cuboid structure as a whole.

[0065] The first crystal 100 is mainly made of silicon dioxide. Although its surface has good transparency, it is easily scratched by external friction or collision during actual use, thus affecting the overall appearance and optical performance. The second crystal 200 is made of plastic. Although it has a certain degree of toughness, its surface hardness is relatively low, and it is also easily scratched during daily wear or assembly.

[0066] In some embodiments, to mitigate the problem of scratches on the crystal surface, the decorative element 10 further includes a covering layer 400 covering the outer surface of at least one of the first crystal 100 and the second crystal 200.

[0067] The covering layer 400, by covering the outer surface of the first crystal 100, or the outer surface of the second crystal 200, or both the first crystal 100 and the second crystal 200, forms a physical barrier that effectively isolates direct contact between external objects and the crystal body, thereby reducing the risk of surface damage caused by friction or impact. This design not only improves the overall durability of the decorative part 10 but also extends its service life.

[0068] It should be noted that the coating layer 400 can also introduce diverse optical properties through material selection and process control, so that the decorative part 10 presents different visual performances under different lighting conditions.

[0069] For example, except for the first surface 210 of the second crystal 200 and the surface of the first crystal 100 facing the first surface 210, the covering layer 400 covers all surfaces of the decorative element 10, namely, the covering layer 400 covers the surface of the first crystal 100 away from the second crystal 200, the outer side of the first crystal 100, the second surface 220 of the second crystal 200, and the outer side of the second crystal 200, thereby forming a complete covering of the decorative element 10; or, the covering layer 400 covers only the first crystal 100, namely, the covering layer 400 covers the surface of the first crystal 100 away from the second crystal 200 and the outer side of the first crystal 100; or, the covering layer 400 covers only the second crystal 200, namely, the covering layer 400 covers the second surface 220 of the second crystal 200 and the outer side of the second crystal 200.

[0070] In some embodiments, the coating layer 400 is formed on the outer surface of at least one of the first crystal 100 and the second crystal 200 by deposition, spraying or electroplating; or, the coating layer 400 is an optical film that coats the outer surface of at least one of the first crystal 100 and the second crystal 200.

[0071] The coating layer 400 can be formed directly on the outer surface of the first crystal 100 or the second crystal 200 through physical or chemical processes, or it can be directly fixed to the crystal surface using a pre-fabricated optical thin film. Deposition (such as physical vapor deposition, PVD) refers to the process of introducing coating materials in gaseous or ionic form onto the crystal surface and condensing them into a solid film to achieve a uniform, dense, and strongly adhesive coating effect. Spraying refers to uniformly applying liquid or powdered coating materials (such as paint) to the crystal surface using a spray gun or similar device, followed by curing to form a stable coating structure. Electroplating utilizes an electric current to reduce and deposit metal ions on the crystal surface as a metal or alloy plating layer to improve surface hardness, wear resistance, or gloss.

[0072] When the coating layer 400 is an optical thin film, it is typically a pre-prepared transparent or translucent film, such as a PVD film or a semi-reflective / semi-transparent film, which can be bonded to the outer surface of the first crystal 100 or the second crystal 200 by means of adhesives or hot pressing. Such optical thin films can possess different optical properties according to design requirements, such as high reflection, low reflection, selective filtering, interference color change, etc., thereby enriching the visual performance of the decorative part 10 under different lighting conditions.

[0073] It should be noted that the various coating layers 400 described above are not mutually exclusive, but can be flexibly selected or combined according to actual manufacturing conditions, material properties, and functional requirements. For example, on the same decorative part 10, a coating layer 400 can be formed on the first crystal 100 using a deposition process, while a highly reflective optical film can be applied to the second crystal 200 using an adhesive method, thereby achieving diversified optical effects.

[0074] In some embodiments, the decorative element 10 includes an intermediate layer 500 connected between the first surface 210 and the first crystal 100, the intermediate layer 500 being an optical adhesive layer and / or a RIM adhesive layer.

[0075] It should be noted that optical adhesive layer refers to a colloidal material with good light transmittance, adhesion and optical matching characteristics. It is usually used to connect two optical elements and ensure that light can be transmitted between them efficiently and uniformly.

[0076] By placing the optical adhesive layer between the first surface 210 of the second crystal 200 and the first crystal 100, not only can a strong bond be achieved between the two, but also reflection and scattering losses between the interfaces can be reduced, thereby improving the optical transmittance of the overall structure. This is especially suitable for applications with high requirements for transparency and refractive index matching.

[0077] Furthermore, a RIM adhesive layer can be formed between the first surface 210 and the first crystal 100 using the RIM (Reaction Injection Molding) process. It should be noted that the RIM process is a manufacturing method in which liquid reactive resin components are injected into a mold under high pressure, where a chemical reaction occurs to form a polymer. It is particularly suitable for bonding and encapsulating complex shapes or irregular interfaces. Using this RIM adhesive layer allows for a highly adaptable adhesive interface between the first crystal 100 and the second crystal 200, not only improving connection strength but also ensuring sealing and cushioning, making it especially suitable for product structures that require a balance between functionality and visual appeal.

[0078] The two connection methods of the first crystal 100 and the second crystal 200 mentioned above correspond to different manufacturing conditions and technical requirements, and can be selectively applied according to the actual production process and product performance requirements. For example, in mass production or scenarios with high requirements for structural strength, the RIM process can be used first to improve processing efficiency and yield. Alternatively, the intermediate layer 500 can use a combination of an optical adhesive layer and a RIM adhesive layer.

[0079] In some embodiments, the second crystal 200 includes a connection structure 221.

[0080] It should be noted that the connecting structure 221 is formed on the second surface 220 of the second crystal 200. The connecting structure can be a buckle, a slot, a screw hole, etc. Taking a buckle as an example, it usually includes components such as elastic arms, engaging protrusions or hook-like structures that can produce a locking effect, used to achieve a detachable or non-detachable fixed connection with external structural components 20 (such as decorative panels, bases, frames or other assembly components).

[0081] The buckle is not a separate additional component, but is directly integrated into the second surface 220 of the second crystal 200. It can be integrally formed with the second crystal 200 or firmly bonded together through processes such as injection molding. Since the second crystal 200 is made of plastic, it has good machinability and structural adaptability, allowing the shape, size, and arrangement of the buckle to be flexibly designed according to actual application requirements. For example, multiple evenly distributed buckles can be set to enhance connection strength, or buckles can be set in corresponding positions according to the mounting holes of the external structural component 20.

[0082] For example, when the decorative component 10 needs to be fixed to a base, it can be quickly installed and positioned by engaging with the corresponding slots or positioning holes on the base using a snap fastener, eliminating the need for additional screws, glue, or other auxiliary fastening methods. This improves assembly efficiency and reduces manufacturing costs. Furthermore, the snap fastener can also provide anti-loosening and shock absorption functions to some extent, helping to improve the structural durability of the product.

[0083] In other embodiments, in addition to the connection structure 221, the second surface 220 of the second crystal 200 can also be fixedly connected to the external structural component 20 by adhesive bonding, thereby providing diverse options for the assembly of the decorative component 10. For example, in application scenarios where seamless assembly is required, adhesive bonding can improve the simplicity and consistency of the overall appearance.

[0084] The bonding of the second crystal 200 can be achieved by coating the second surface 220 with an adhesive. This adhesive can be a thermosetting, UV-curing, or room-temperature curing organic colloidal material, such as epoxy resin, UV adhesive, acrylic adhesive, or silicone adhesive. These materials possess good adhesion and chemical stability, making them suitable for firmly bonding the second surface 220 of the second crystal 200 to the surface of common structural components 20 such as metal, plastic, ceramic, or glass. Furthermore, since the second crystal 200 itself is made of plastic, its surface properties facilitate stable bonding with various adhesives, thereby ensuring high mechanical strength and long-term reliability at the connection interface.

[0085] The dazzling effect presented by the decorative element 10 in this embodiment can be quantified by simulation, such as... Figure 7 As shown, when an external light source illuminates the surface of the decorative element 10, the ratio of the highest brightness to the lowest brightness of the decorative element 10 is greater than 200%, indicating that the decorative element 10 has a dazzling effect; in contrast, if the second surface 220 does not have a textured structure 300, such as Figure 8 As shown, the ratio of the highest brightness to the lowest brightness of the decorative element 10 is less than 50%, and therefore the decorative element 10 does not have a dazzling effect.

[0086] In summary, the embodiments of this application provide a decorative part 10, which solves the problems of difficult processing of complex concave textures in silica-containing crystals and lack of brilliance under external light source by combining a second crystal 200 with a textured structure 300 on the basis of a first crystal 100 with better luster. Ultimately, it achieves a decorative effect that combines transparency, luster and brilliance.

[0087] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
