Description

Technical Field

[0001] The utility model relates to the technical field of watch accessories, and particularly relates to a watch protective cover with an optical color effect. Background Art

[0002] In modern life, as an item with both practical functions and fashionable decorations, watches are used in an increasingly wide range of scenarios. From daily work and life to various sports occasions, watches play an important role. With the continuous progress of technology, the types of watches are constantly enriched, covering traditional mechanical watches, accurate quartz watches, and powerful smart watches, etc.

[0003] However, watches face many potential risks during daily use. Whether it is accidental scratches, collisions, or contact with sharp objects, they may damage the appearance of the watch. For some watches with precise internal structures, severe external impacts may even affect their normal operation. To protect watches, watch protective covers have gradually become the choice of many consumers.

[0004] Traditional watch protective covers usually mainly consider practicality, and tend to choose durable and abrasion-resistant materials in terms of material selection, but are often relatively conservative in appearance design. These protective covers usually adopt a single color or simple patterns, lacking unique design elements and a sense of fashion. In today's era of pursuing personalization and fashion trends, consumers' requirements for watch accessories are no longer limited to protection functions only. They hope that the watch protective cover can become a carrier of fashion expression and match their personality and style.

[0005] With the continuous improvement of people's living standards, the demand for fashion accessories is also becoming increasingly diverse. Among many fashion products, those with unique designs and high-quality appearances often attract consumers' attention more. For example, in the field of mobile phone accessories, some mobile phone cases with novel designs and excellent materials can not only protect the mobile phone but also become a fashion embellishment. However, in the watch accessory market, there are few products that can achieve a good balance between protection functions and fashionable appearances.

[0006] At the same time, with the development of society, people's aesthetic concepts are also constantly changing. The simple, grand, and fashionable design styles are increasingly favored by consumers. For watch protective covers, how to integrate more fashion elements and improve the overall quality and beauty of the products on the premise of meeting the basic function of protecting watches has become an important issue faced by current watch accessory manufacturers.

[0007] In summary, developing a watch protective cover that can not only effectively protect watches but also has a unique fashionable appearance has important practical significance for meeting consumers' needs and promoting the development of the watch accessory market. Summary of the Invention

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 3 , in the embodiments of the present utility model, a watch protective case with an optical color-changing effect includes a protective case body 1, and the protective case body 1 is used to detachably cover the surface of the watch body 11;

[0032] The protective case body 1 has a display window 2, and a textured surface 3 is arranged along the perimeter of the display window 2, and a texture structure 4 with an optical color-changing effect is engraved on the textured surface 3.

[0033] In the technical solution of the present utility model, the protective case body 1 is detachably sleeved on the surface of the watch body 11. Specifically, through reasonable size design and the use of elastic materials, the inner diameter of the protective case body 1 is slightly smaller than the outer diameter of the watch body 11, so that the protective case body 1 can tightly wrap the watch without over-compressing the watch. Elastic materials such as silicone and TPU have good flexibility and elastic recovery force, and can adapt to the shape change of the watch during the installation and disassembly process, facilitating the user to remove or install the protective case at any time to meet the needs of different usage scenarios;

[0034] The display window 2 is provided to ensure that the screen of the watch can display information normally without affecting the user's operation of the watch functions. The size and shape of the display window 2 match the screen of the watch, and usually transparent materials are used to ensure good light transmission. Or, the display window 2 adopts a hollow design to achieve the effect of ensuring that the screen of the watch can display information normally;

[0035] The texture surface 3 is arranged along the periphery of the display window 2 and is a key part of the entire design. The texture surface 3 is made through advanced process technologies, such as high-precision mold forming, fine engraving or micro-nano processing. First, a mold with a specific shape and depth is made according to the design requirements, and then the material is injected into the mold. After heating, cooling and other process processes, the material is formed into a protective cover body 1 with a texture structure 4, or laser engraving and other technologies are used to accurately depict delicate textures on the surface of the protective cover. These textures can be regular geometric patterns, such as lines, squares, circles, etc., or irregular natural patterns, such as wood grain, stone grain, etc. The depth and spacing of the textures are carefully adjusted and designed to achieve the best optical effect;

[0036] In summary, by providing a textured surface 3 around the display window 2 of the protective cover body 1, and engraving a texture structure 4 with an optical colorful effect on the textured surface 3, a unique fashion element is added to the watch protective cover. The textured structure 4 can present rich color changes and light and shadow effects under different lighting conditions. The principle is that the texture reflects, refracts and scatters the light. When the light is irradiated on the textured surface 3, due to the different shapes and depths of the textures, the light will be reflected and refracted at different angles, resulting in interference and diffraction phenomena, thereby forming a colorful optical effect; for example, in the sun, the textured surface 3 may present rainbow colors; under indoor lighting, it will present a soft luster. Users can choose different texture styles according to their preferences and different occasions to show their personality and taste;

[0037] Compared with traditional single-color or simple-pattern protective cases, the textured surface 3 with optical colorful effects makes the watch case more artistic and decorative. It can be matched with various fashion outfits, whether it is casual wear, formal wear or sportswear, and can add highlights to the overall look. At the same time, this unique design also makes the watch stand out among many accessories and become the focus of people's attention.

[0038] Furthermore, the texture surface 3 is arranged around the edge of the display window 2, which increases the thickness and strength of the protective cover to a certain extent. The texture structure 4 can disperse the external force impact and reduce the direct pressure on the screen. In particular, when the watch is accidentally dropped or hit, the texture surface 3 can play a buffering role and reduce the risk of the screen being broken. In addition, the texture surface 3 can also prevent impurities such as dust and moisture from entering the interior of the watch, protecting the precision parts of the watch.

[0039] Furthermore, a watch case with an optical color-changing effect has high recognition and competitiveness in the market. This unique design can attract more consumers' attention and increase the added value of the product. For watch manufacturers and sellers, launching such a case can enrich the product line, meet the needs of different consumers, increase market share and profit margins. At the same time, a high-quality case can also enhance the image and reputation of the watch brand and bring a better shopping experience to consumers.

[0040] In the embodiment of the present utility model, the texture surface 3 includes a first texture surface 5 and a connected second texture surface 6. The first texture surface 5 and the second texture surface 6 are respectively located on the end face and the side face of the display window 2.

[0041] The texture surface 3 is divided into a first texture surface 5 and a second texture surface 6. This design is based on a comprehensive consideration of the display requirements and optical effects of different parts of the watch. The end face of the display window 2 is usually the most prominent part on the front of the watch. Setting the first texture surface 5 can add a unique visual focus to the watch from the front view, while the second texture surface 6 on the side can echo the first texture surface 5 from different viewing angles to form a coherent visual effect; that is, through the setting of the first texture surface 5 and the second texture surface 6, the watch is decorated in all directions. Whether observing the watch from the front or the side, unique textures and optical color-changing effects can be seen, making the watch attractive from any angle. This all-round aesthetic effect meets the users' pursuit of fashion and personalization;

[0042] Specifically, the first texture surface 5 is located on the end face of the display window 2 and is usually directly irradiated by light. Therefore, its texture design pays more attention to the reflection and refraction effects of light to produce a strong visual impact. A deeper texture depth and a higher texture density can be adopted to make the light reflect and interfere multiple times on the first texture surface 5, thus forming rich color changes; the second texture surface 6 is located on the side face of the display window 2 and mainly plays a role in assisting and supplementing the optical effect of the first texture surface 5. Due to the different light irradiation angles on the side, the design of the second texture surface 6 pays more attention to capturing and scattering the side light. A shallower texture depth and a sparser texture layout can be adopted to make the light scatter softly on the second texture surface 6, forming a contrast with the strong reflection of the first texture surface 5 and increasing the overall sense of hierarchy and three-dimensionality;

[0043] Furthermore, for the connection between the first textured surface 5 and the second textured surface 6, a smooth transition design can be adopted. Through precise process control, the two textured surfaces 3 are seamlessly connected at the junction, avoiding obvious edges or faults. This connection method is not only more aesthetically pleasing in appearance but also ensures a more natural transition of light between different textured surfaces 3, enhancing the overall optical iridescent effect. During the manufacturing process, the first textured surface 5 and the second textured surface 6 are designed and processed separately according to the shape and size of the watch. For example, for a circular watch, the first textured surface 5 can adopt an annular pattern design, while the second textured surface 6 can have a curved texture layout according to the curvature of the watch side to better adapt to the appearance of the watch.

[0044] In the embodiment of the present utility model, the texture structures 4 of the first textured surface 5 and the second textured surface 6 are naturally integrated at the connection between the first textured surface 5 and the second textured surface 6.

[0045] Through this design, the naturally integrated texture structure 4 makes the watch case more beautiful and integral in appearance, without obvious connection marks, making the case look like a seamless whole, enhancing the delicacy and high-end feeling of the product. Whether observing the watch from the front or the side, smooth and natural texture lines can be felt, enhancing the visual attractiveness of the watch.

[0046] Specifically, in order to achieve the natural integration of the texture structures 4 of the first textured surface 5 and the second textured surface 6 at the connection, the shapes, angles, and texture orientations of the two textured surfaces 3 need to be fully considered during the design process. For example, if the display window 2 of the watch case is circular or oval, then an arc transition needs to be adopted at the connection between the first textured surface 5 and the second textured surface 6, so that the texture can naturally transition from one surface to another along the arc contour.

[0047] In the texture design, fusion is achieved through gradient, transitional colors, or similar texture elements. For example, the texture density or depth can be gradually reduced at the connection between the first textured surface 5 and the second textured surface 6 to make the change of the texture from one surface to another more smooth, or the same texture pattern can be used, but the size, color, or direction of the pattern is adjusted at the connection to achieve the effect of natural integration.

[0048] In the manufacturing process, high-precision processing technologies are adopted to ensure the texture accuracy and quality at the connection. For example, laser engraving technology can be used to precisely control the shape and depth of the texture, making the texture at the connection more delicate and natural. At the same time, through special surface treatment processes such as polishing and frosting, the smoothness and texture at the connection can be further enhanced, making the texture fusion more perfect.

[0049] In the embodiment of the present utility model, the texture surface 3 further includes a third texture surface 7, and the third texture surface 7 is smoothly connected between the first texture surface 5 and the second texture surface 6 in an arc shape.

[0050] The introduction of the third texture surface 7 and its smooth connection between the first texture surface 5 and the second texture surface 6 in an arc shape is based on a comprehensive consideration of ergonomics and aesthetics. The arc design can better fit the curve of the watch, adapt to the shapes and sizes of different watches, ensure that the protective cover is tightly combined with the watch, and is not easy to loosen or fall off; from an optical perspective, the arc-shaped third texture surface 7 can reflect and refract light at different angles, cooperate with the first texture surface 5 and the second texture surface 6, and form a richer and three-dimensional optical dazzling effect. For example, when light shines on the arc-shaped third texture surface 7, a curved light path will be generated, causing the color to change in different directions, enhancing the overall visual hierarchy; the third texture surface 7 naturally merges at the connection of the first texture surface 5 and the second texture surface 6 just like the texture structure 4 of the first texture surface 5 and the second texture surface 6 described above.

[0051] In the embodiment of the present utility model, the texture structure 4 includes a micro-nano structure (not shown), and the micro-nano structure is periodic or aperiodic.

[0052] The inclusion of the micro-nano structure in the texture structure 4 is based on an in-depth understanding of optical principles and material properties. The micro-nano structure refers to tiny structures with dimensions in the micrometer or nanometer range, and these structures can have unique effects on light. By introducing the micro-nano structure into the texture surface 3, the behaviors of light reflection, refraction, scattering, etc. can be precisely controlled, thereby achieving an optical dazzling effect;

[0053] For the periodic micro-nano structure, its design principle is to utilize the periodic structure to generate interference, diffraction and other phenomena for light of a specific wavelength. For example, when light shines on the periodically arranged micro-nano structure, according to the period and size of the structure, certain wavelengths of light can be selectively enhanced or weakened, thereby generating specific colors and optical effects; the aperiodic micro-nano structure conducts complex scattering and reflection of light through randomly distributed tiny structures, generating more natural and diverse optical effects;

[0054] During the manufacturing process, advanced microfabrication technologies such as photolithography and nanoimprinting can be used to precisely manufacture the required micro-nano structure. These technologies can control the shape and structure of materials at the microscale, ensuring that the size and distribution of the micro-nano structure meet the design requirements.

[0055] In the embodiment of the present utility model, a coating layer (not shown) is provided on the protective cover body 1 at the position of the texture surface 3.

[0056] A coating layer is provided on the texture surface 3 of the protective cover body 1 to further enhance the optical color effect and improve the performance of the protective cover. The material of the coating layer is usually selected from substances with specific optical properties, such as metal oxides, nitrides, etc. These materials can be uniformly deposited on the surface of the texture surface 3 by methods such as physical vapor deposition (PVD) and chemical vapor deposition (CVD);

[0057] The coating layer can perform specific reflection, refraction, and interference on light, and cooperate with the micro-nano structure of the texture surface 3 to produce a richer and stronger optical color effect. For example, selecting a metal coating with a high reflectivity can enhance the reflection of light and make the color more vivid; selecting a dielectric coating with a specific refractive index can adjust the propagation direction of light and produce unique optical phenomena;

[0058] At the same time, the coating layer can also play a role in protecting the texture surface 3. It can prevent the texture surface 3 from being eroded by the external environment, such as wear, scratching, oxidation, etc., thereby extending the service life of the protective cover.

[0059] In the embodiment of the present utility model, a screen display protective film 8 is connected to the protective cover body 1 at the display window 2; a step structure 9 for connecting the screen display protective film 8 is provided inside the display window 2.

[0060] Connecting the screen display protective film 8 to the protective cover body 1 at the display window 2 is to provide additional protection for the display screen of the watch. The display screen of the watch is usually the part most vulnerable to scratching, collision, and dust pollution, and the screen display protective film 8 can effectively prevent these damages;

[0061] A suitable connection method needs to be designed on the protective cover body 1 for connecting the screen display protective film 8. Providing a step structure 9 at the display window 2 is a common connection method. The step structure 9 can provide a stable installation position for the screen display protective film 8, enabling it to be firmly connected to the protective cover; the size and shape of the step structure 9 need to match the screen display protective film 8 to ensure the stability and tightness of the installation. Usually, the depth and width of the step structure 9 will be slightly larger than the thickness and size of the screen display protective film 8, so that the screen display protective film 8 can be easily installed on the step and closely fit with the protective cover body 1.

[0062] In the embodiment of the present utility model, the texture surface 3 further includes a fourth texture surface 10 located inside the display window 2 and corresponding to the step structure 9.

[0063] The fourth textured surface 10 is arranged inside the display window 2 and corresponds to the step structure 9, so as to further enhance the overall aesthetics and uniqueness of the protective case without affecting the normal display of the watch display screen. When observing the watch from a specific angle, the fourth textured surface 10 can echo with other textured surfaces 3 on the outside, forming a richer visual hierarchy and jointly creating a unique optical color effect.

[0064] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
