[0002] With the development of fashion technology and the diversification of consumer aesthetic needs, watches have not only become time measurement tools, but also become symbols of personal style and identity. As the main body of the appearance of the watch, the material, design and process of the watch case directly affect the overall aesthetics and wearing experience of the watch. In recent years, in order to pursue lighter weight, higher strength and unique visual effects, carbon fiber, as a high-performance composite material, has begun to be applied in the manufacturing of high-end watch cases.

[0003] In the prior art, the decoration of carbon fiber watch cases mainly depends on the texture and color variation of carbon fiber itself. Due to the unique woven texture and luster of carbon fiber, different visual effects can be produced by different weaving methods (such as plain weave, twill or satin). However, this decoration method is relatively simple, mainly relying on the natural properties of carbon fiber material, lacking sufficient individuality and innovation. In addition, the traditional carbon fiber watch case is usually limited in color, mostly black or dark, which is difficult to meet the needs of consumers for color richness and individuality.

[0004] Therefore, it is necessary to provide a carbon fiber composite layer layering structure to enrich the decoration effect of the watch case and improve the aesthetics. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0028] The embodiments of the present application will be described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0029] It should be noted that when one component is considered to be "connected" to another component, it can be directly connected to the other component or a middle component can exist at the same time. When one component is considered to be "provided on" another component, it can be directly provided on the other component or a middle component can exist at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and the like used herein are for illustrative purposes only.

[0030] The embodiments of the present application provide a carbon fiber composite layer layup structure, comprising: carbon fiber composite layers stacked layer by layer, each of the carbon fiber composite layers being generated along a unidirectional extension direction, the carbon fiber composite layer comprising a carbon fiber layer along the unidirectional extension direction, a gold wire, and a resin, the gold wire being provided on the carbon fiber layer, the resin being used for impregnating and curing the carbon fiber layer and the gold wire, and a horizontal included angle between the gold wire and the carbon fiber layer being A, and an included angle B between each of the carbon fiber composite layers being observed along a direction perpendicular to a layer plane of each of the carbon fiber composite layers, satisfying a relationship:

[0031] 0°≤A≤90°;

[0032] 0°≤B≤90°.

[0033] The above-provided layering structure of the carbon fiber composite layer sets the horizontal angle between the gold wire and the carbon fiber layer in each carbon fiber composite layer as A, which ranges from 0°≤A≤90°. By adjusting this angle, the designer can control the arrangement of the gold wire relative to the carbon fiber texture, thereby achieving different decorative effects. The angle between different carbon fiber composite layers is set as B, which ranges from 0°≤B≤90°. This angle controls the relative positions between different carbon fiber composite layers, further enhancing the three-dimensional effect and multi-level decorative effect of the composite material. Thus, not only is the decorative effect of the watch case enriched, the aesthetic degree is improved, but also the structural strength and service life of the watch case are guaranteed, meeting the needs of modern consumers for personalized and high-quality watches.

[0034] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] According to Figures 1-7 , the present application provides a layering structure 100 of a carbon fiber composite layer 10, comprising: carbon fiber composite layers 10 stacked layer by layer, each of the carbon fiber composite layers 10 being generated along a unidirectional extension direction, the carbon fiber composite layer 10 comprising a carbon fiber layer 11 along a unidirectional extension direction, a gold wire 12, and a resin 13, the gold wire 12 being arranged on the carbon fiber layer 11, the resin 13 being used to impregnate and cure the carbon fiber layer 11 and the gold wire 12, and the horizontal angle between the gold wire 12 and the carbon fiber layer 11 being A, and between each of the carbon fiber composite layers 10 there is an angle B along the direction perpendicular to the layer direction of each of the carbon fiber composite layers 10, satisfying the relationship:

[0036] 0°≤A≤90°, 0°≤B≤90°.

[0037] Specifically, the unidirectional extension direction of the carbon fiber layer 11 refers to the arrangement of the carbon fiber layer 11 along a specific direction, which gives the material excellent tensile strength and rigidity. The resin 13 ensures the effective combination of carbon fiber and gold wire 12 during material forming. During the curing process, the resin 13 not only acts as an adhesive, but also increases the toughness of the material, so that a firm bonding interface is formed between the gold wire 12 and the carbon fiber layer 11.

[0038] Preferably, when 0°≤A<30°, the gold wire 12 is closer to parallel with the carbon fiber layer 11, and the decorative effect is relatively restrained, which is suitable for designs that pursue low-key texture effects. When 30°≤A≤60°, the gold wire 12 can visually provide appropriate interlacing, forming a clear decorative effect, which is suitable for designs that hope to increase visual impact. When 60°<A≤90°, especially close to 90°, the gold wire 12 intersects perpendicularly with the carbon fiber layer 11, which can present a strong contrast texture, which is suitable for designs that emphasize decoration. More preferably, when the angle A is 90°, the gold wire 12 intersects perpendicularly with the horizontal direction of the carbon fiber layer 11, and the gold wire 12 that is perpendicular to the carbon fiber layer 11 can produce a clear contrast, making the gold wire 12 more prominent; when the angle A is 45°, the gold wire 12 interweaves with the carbon fiber layer 11, which can form a more dynamic visual effect, and the oblique intersection of the gold wire 12 and the carbon fiber layer 11 produces a kind of visual impact of dislocation; when the angle A is 0°, the gold wire 12 is parallel to the carbon fiber layer 11, which can form parallel gold stripes in the visual effect, and the decorative effect is more coordinated.

[0039] Preferably, the included angle B between the stacked carbon fiber composite layers 10 defines the relative angle between different carbon fiber layers 11. In the embodiments of the present application, when B is 0°, the fiber extension directions of all carbon fiber composite layers 10 remain consistent, ensuring high strength of the material; and when B is 45° or 90°, different carbon fiber layers 11 are stacked at different angles, forming a structure with stronger three-dimensionality, and also enhancing the strength and rigidity of the overall lamination structure.

[0040] In summary, through the carbon fiber composite layers 10 that are stacked and laid layer by layer, the designer can set the direction, angle and thickness of each carbon fiber composite layer 10 as needed, the gold wire 12 is embedded on the carbon fiber layer 11 at a specific included angle A, and the resin 13 is impregnated and then cured, finally forming a composite material with high strength and high aesthetic degree. The angle design of the carbon fiber layer 11 and the gold wire 12, and the control of the interlayer included angle B, enable the watch case to present a unique decorative effect, and also maintain the mechanical properties of the material.

[0041] In a specific embodiment, the carbon fiber layer 11 includes a mounting groove 11a along a unidirectional extension direction, the mounting groove 11a is provided on the layer surface of the carbon fiber layer 11, and the gold wire 12 is provided in the mounting groove 11a.

[0042] In the first embodiment, before the carbon fiber layer 11 is cured, a mounting groove 11a is reserved to accommodate and fix the gold wire 12. When the gold wire 12 is laid on the same level as the carbon fiber layer 11 and the angle between the gold wire 12 and the carbon fiber layer 11 is 0°, the gold wire 12 needs to be closely attached to the carbon fiber layer 11 during the laying process. During the subsequent resin impregnation 13 and curing process, the gold wire 12 will form a tight bond with the carbon fiber layer 11, so that part of the gold wire 12 will be embedded in the carbon fiber layer 11, thereby forming the mounting groove 11a. During the curing process, the resin 13 will firmly bond the gold wire 12 and the carbon fiber layer 11 together. Applying pressure through a vacuum bag process or a hot pressing process can better fit and embed the gold wire 12 into the structure of the surface layer.

[0043] In Example 2, the carbon fiber layer 11 is preliminarily cured. A unidirectional mounting groove 11a is cut into the surface of the preliminarily cured carbon fiber layer 11 using a cutting device. The gold wire 12 is inserted into the mounting groove 11a and secured with an adhesive such as resin 13. Finally, the entire carbon fiber layer 11 is finely ground and polished to ensure a smooth, flawless surface that blends perfectly with the gold wire 12.

[0044] In a specific embodiment, the carbon fiber layer 11 further includes a continuous first fiber layer 111 and a second fiber layer 112 , and the gold wire 12 is disposed between the first fiber layer 111 and the second fiber layer 112 .

[0045] Specifically, the thickness of the first fiber layer 111 and the second fiber layer 112 can be adjusted according to actual design needs, so that the gold wire 12 is embedded in the carbon fiber layer 11, providing visual appeal and meeting consumers' demand for personalized and unique designs. The first fiber layer 111 or the second fiber layer 112 can be woven first, and then on the laid first fiber layer 111 or the second fiber layer 112, the gold wire 12 is embedded in a specific position between the first fiber layer 111 and the second fiber layer 112 according to the design requirements to ensure the uniform distribution and fixed position of the gold wire 12. The installation of the gold wire 12 can be carried out through a pre-set groove or other form. After the gold wire 12 is embedded, the second fiber layer 112 is laid on top of it to ensure that the gold wire 12 is completely covered and fixed between the first and second layers. Resin 13 is applied between the two layers of fiber for impregnation to ensure that the resin 13 penetrates the interface between the gold wire 12 and the carbon fiber layer 11. Then a curing process is performed to complete the formation of the entire composite layer.

[0046] In a specific embodiment, the carbon fiber layer 11 has a plurality of carbon fiber filaments 11 b extending unidirectionally along the carbon fiber composite layer 10 , and the carbon fiber layer 11 is woven from the plurality of carbon fiber filaments 11 b .

[0047] Specifically, the unidirectional carbon fiber filaments 11b are arranged along the main stress direction of the composite layer, which can greatly improve the tensile strength of the composite material in this direction.

[0048] In an embodiment, the thickness of the carbon fiber layer 11 is in the range of 0.1mm-0.3mm.

[0049] Specifically, in the design of the watch case, the thickness of the carbon fiber layer 11 will affect the overall strength, weight and appearance. The thickness of the carbon fiber cloth varies depending on the type of weaving, fiber diameter and the amount of resin 13 used. Generally, the thickness of a single layer of carbon fiber layer 11 is about 0.1mm-0.3mm. Preferably, the thickness of the watch case is in the range of 1mm-4mm, depending on the design and the required strength. In order to achieve this thickness, 5 to 10 layers of carbon fiber layer 11 can be stacked to provide strength and achieve a decorative effect.

[0050] In an embodiment, the diameter of the carbon fiber filaments 11b is in the range of 5μm-10μm, and the diameter of the gold filaments 12 is in the range of 10μm-40μm.

[0051] Specifically, the carbon fiber filaments 11b are high-strength, lightweight materials composed of carbon atoms, with excellent tensile strength and rigidity. They usually exist in the form of single filaments, each carbon fiber filament 11b having a diameter of 5 to 10 microns. The carbon fiber filaments 11b are woven into carbon fiber layers 11, with common specifications being 3K, 6K, 12K, etc.

[0052] In an embodiment, the volume fraction of the gold filaments 12 in the carbon fiber composite layer 10 is in the range of 5%-10%.

[0053] Specifically, the gold filaments 12 are used to increase the strength and wear resistance of the case, while also providing a certain decorative effect.

[0054] In an embodiment, the resin 13 is a thermosetting resin 13 or a thermoplastic resin 13.

[0055] Specifically, in the embodiments of the present application, during the manufacturing process of the carbon fiber composite material, the thermosetting resin 13 penetrates between the carbon fiber filaments 11b through an impregnation process, filling the gaps between the materials and ensuring tight bonding between each layer of material. After reaching a certain temperature, the thermosetting resin 13 begins to undergo a chemical cross-linking reaction, gradually changing from a liquid state to a solid state. During this process, a strong cross-linked network is formed between the molecular chains of the resin 13, improving the structural strength and stability of the material. Once the curing is complete, the structure of the thermosetting resin 13 will no longer be affected by heat changes. The material can still maintain its mechanical properties under high temperature or harsh environments.

[0056] In another embodiment, the thermoplastic resin 13 softens when heated, enters between the carbon fiber layers 11, and is combined with the carbon fiber material through hot pressing or other processing techniques to form a stable composite structure. The thermoplastic resin 13 hardens after cooling, but can be heated and softened again for adjustment and processing in subsequent processes. This characteristic enables the thermoplastic resin 13 to flexibly adjust the shape of the material according to design requirements. Unlike the thermosetting resin 13, the plasticity of the thermoplastic resin 13 enables secondary processing and recycling, which is of great significance in product manufacturing and environmentally friendly design.

[0057] In a specific embodiment, the carbon fiber composite layer 10 further comprises a reinforcing fiber layer 14, which is arranged between the carbon fiber layer 11 and the gold wire 12.

[0058] Specifically, the reinforcing fiber layer 14 can provide additional support between the carbon fiber layer 11 and the gold wire 12 to prevent the gold wire 12 from affecting the structural integrity of the carbon fiber layer 11 during use. After the carbon fiber layer 11 is laid, the reinforcing fiber layer 14 is laid on the surface of the carbon fiber layer 11. The reinforcing fiber layer 14 can use different materials (such as glass fiber, aramid fiber, etc.) according to the mechanical requirements, and use a specific weaving or arrangement to ensure the strength and toughness of the composite material.

[0059] In an embodiment of the present application, a watch case 200 is provided, which comprises the layup structure of any one of the carbon fiber composite layers 10.

[0060] By using the layup structure of the carbon fiber composite layer 10 on the watch case, the watch case can to some extent play an aesthetic and decorative effect, thereby meeting the needs of consumers for color richness and personalization.

[0061] The above only describes the embodiments of the present application, and it should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present application, and these improvements are within the protection scope of the present application.
