Description

Technical Field

[0001] The present application relates to the field of jewelry technology, and in particular to a kind of colorful jewelry. Background Art

[0002] Most existing precious metal jewelry uses traditional carving and engraving techniques to enhance its beauty. This method can only rely on changing the shape or surface pattern of the jewelry to enhance its beauty, while the surface of the jewelry still shows the original color of the precious metal. This method has a relatively limited effect on improving the beauty of the jewelry.

[0003] To enhance the color of precious metal jewelry, some jewelry uses electroplating or oxidation reactions to form a plating layer or oxide film on the surface of the precious metal, thereby utilizing the thin-film interference effect to create color on the jewelry surface. However, as precious metal jewelry is worn for a long time, the coating on the surface will be affected by factors such as aging and wear, causing it to fade and fall off. This can cause parts of the jewelry surface to lose their color, resulting in an uneven color distribution and a serious reduction in the jewelry's aesthetic appeal. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a colorful jewelry, which uses improvements to the physical structure of the precious metal body to replace the traditional coating method, ensuring that the jewelry surface can show color while not easily fading or falling off after long-term wearing.

[0005] An embodiment of the present application provides a colorful jewelry, including a precious metal body, at least one side of which has multiple surfaces at angles to each other, and corrugations are provided on the surfaces. The corrugations include multiple micro grooves arranged at intervals, and micro convex strips located between two adjacent micro grooves, and the micro grooves extend in a direction perpendicular to their arrangement direction; the multiple micro grooves arranged in parallel form a reflective grating, and light is irradiated on the surface of the micro grooves and reflected to produce diffraction, and light of different wavelengths is diffracted in different directions, so that at least part of the surface appears colorful.

[0006] In an optional manner, the distance between two adjacent micro grooves is any value within the range of 0.5 μm-3 μm.

[0007] In an optional embodiment, the corrugation is generally sawtooth-shaped, the concave parts of the sawtooth form micro grooves, and the convex parts form micro convex strips; or, the corrugation is generally wavy-shaped, the concave parts of the wavy shape form micro grooves, and the convex parts form micro convex strips.

[0008] In an optional embodiment, a V-shaped groove is provided on at least one side of the precious metal body. The V-shaped groove is strip-shaped as a whole. The inner wall of the V-shaped groove forms a surface. A plurality of micro grooves and a plurality of micro convex strips are arranged along the extension direction of the V-shaped groove.

[0009] In an optional embodiment, the colorful jewelry further includes a precious metal wire, which is fixedly connected to both ends of the V-shaped groove and arched relative to the V-shaped groove.

[0010] In an optional embodiment, the precious metal wire is provided with decorative patterns.

[0011] In an optional embodiment, the precious metal body is circular, elliptical, teardrop-shaped, petal-shaped or star-shaped, and includes multiple V-grooves, which are evenly distributed along the circumference of the precious metal body, and all the V-grooves extend from the center to the edge of the precious metal body.

[0012] In an optional manner, the noble metal body is in the shape of a straight bar or a curved bar, and the V-shaped grooves include a plurality of V-shaped grooves, which are arranged along the extension direction of the noble metal body.

[0013] In an optional embodiment, the precious metal body is fan-shaped or partially annular with radial and circumferential directions, and the V-grooves include multiple V-grooves, which are stacked radially to form multiple layers, and the multiple V-grooves in each layer are arranged circumferentially.

[0014] In an optional embodiment, a decorative piece and / or a hollow portion is provided on the precious metal body.

[0015] In the colorful jewelry provided in the embodiments of the present application, a reflective grating is formed by multiple microgrooves arranged in parallel within the corrugations on the surface of the precious metal body. When light strikes the microgrooved surface and reflects, it diffracts, splitting the light. Light of different wavelengths (equivalent to different colors) is diffracted in different directions, resulting in the appearance of colorful light spots on the surface of the colorful jewelry. Compared to film coating, this method does not require the precious metal to be bonded with other materials, thus not affecting the purity and quality of the precious metal material. Moreover, the reflective grating formed is a physical structure on the precious metal. Due to the extremely high chemical stability of the precious metal itself, it is less likely to fade or fall off after long-term wear, and can still present well-distributed colors.

[0016] In addition, at least one side of the precious metal body has multiple surfaces that are angled to each other, and each surface is provided with corrugations. This ensures that no matter from what angle the light shines on the precious metal body, and no matter from what angle the human eye observes the precious metal body, there can basically be some surfaces that reflect and diffract the colored light so that it enters the human eye, ensuring that users can effectively observe the dazzling colors presented on the colorful jewelry.

[0038] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense.

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0039] In order to address the problem that precious metal jewelry, which produces color by forming a thin film on the surface through electroplating or oxidation reaction, is prone to fading, falling off, and other problems that affect the aesthetics after long-term use, this application considers physically modifying the precious metal material itself to ensure that it is not prone to fading, falling off, etc. after long-term wear, and can still produce well-distributed colors and have good aesthetics.

[0040] Drawing inspiration from the fact that CDs produce rainbow colors under lighting conditions, theoretical research has found that this is because the closely arranged spiral grooves on the surface of the CD form a reflective grating. When white light hits the surface of these spiral grooves and is reflected, light of different wavelengths will be diffracted to different directions, thus forming a rainbow spot on the surface.

[0041] Based on this, the present application considers processing a reflective grating structure on the surface of precious metal jewelry, which uses the diffraction of light to make the surface appear rainbow-like, thereby enhancing the beauty of the jewelry. Compared with coating, this method does not require combining other materials with the precious metal, so it does not affect the purity and texture of the precious metal material. Moreover, the reflective grating formed is a physical structure on the precious metal. Due to the extremely high chemical stability of the precious metal itself, it is not prone to fading or shedding after long-term wear, and can still present a well-distributed color.

[0042] However, during practical testing, it was found that if the surface of precious metal jewelry is flat, even if a reflective grating structure is processed on the plane, due to the influence of the diffraction direction, basically no color can be observed from the perspective facing the surface of the precious metal jewelry. Although color can be seen from a slightly off-center perspective, the improvement in the aesthetics of the jewelry is really limited, because users generally need to observe precious metal jewelry from the front, whether purchasing or wearing it.

[0043] In this regard, the present application further considers processing the surface of the precious metal body into surfaces with multiple faces in different directions, and processing a reflective grating structure on each surface, so as to ensure that when the precious metal jewelry is observed from different angles under lighting conditions, basically a part of the surface will appear in color, and the precious metal jewelry as a whole will show good beauty.

[0044] See also Figure 1 The figure shows a three-dimensional view of the colorful jewelry provided by an embodiment of the present application. As shown in the figure, the colorful jewelry 100 includes a precious metal body 110, and at least one side of the precious metal body 110 has multiple surfaces 111 at angles to each other, and corrugations 112 are provided on the surface 111.

[0045] It should be noted that the "surface 111" herein is not an absolutely flat surface. While the surface is generally flat from a macroscopic perspective, it is actually characterized by minute ripples 112 from a microscopic perspective. Furthermore, the term "at an angle to each other" here refers to the fact that some surfaces 111 are not parallel to each other but have a certain angle between them. This angle can be acute, right, or obtuse. Of course, to allow more light to reach the surface 111 and better observe the colors produced on the surface 111, the angles between different surfaces 111 are preferably set to obtuse.

[0046] In the actual processing and manufacturing process, the initial precious metal blank to be processed can be in the form of a sheet with complete planes on both sides, and the precious metal blank can be turned by a CNC machine tool to form multiple small faces facing different directions on the complete plane. The small faces formed by the processing are the surface 111 mentioned above.

[0047] See also Figure 2 Shown in Figure 1 As shown in the enlarged structure at A, the corrugation 112 includes a plurality of micro grooves 1121 arranged at intervals, and micro convex strips 1122 located between two adjacent micro grooves 1121. Figure 2 The micro grooves 1121 and the micro convex strips 1122 are arranged in a direction perpendicular to the arrangement direction ( Figure 2 The structure extends in the direction indicated by the double arrow Y.

[0048] In the actual production process, the micro grooves 1121 and micro ridges 1122 in the corrugation 112 can be formed on the surface 111 by an existing confidential machining CNC machine tool with an ultrasonic actuator. The high-frequency vibration of the ultrasonic actuator is used to make the tool head of the machine tool move up and down repeatedly at a high frequency. At the same time, through the horizontal movement of the tool head, or the translation or rotation of the fixture, the tool head can process the corrugation 112 on the surface of the precious metal body on the fixture.

[0049] Specifically, the corrugation 112 may be as follows Figure 2As shown in FIG, the whole is sawtooth-shaped, and accordingly, the sawtooth-shaped concave portion forms micro grooves 1121, and the convex portion forms micro convex strips 1122. In addition, the corrugation 112 can also be wavy as a whole, and similarly to the sawtooth shape, the wavy concave portion forms micro grooves 1121, and the convex portion forms micro convex strips 1122.

[0050] Multiple microgrooves 1121 arranged in parallel form a reflective grating. When light strikes the surface of the microgrooves 1121 and is reflected, diffraction occurs, causing the light to split. Light of different wavelengths (equivalent to different colors) will be diffracted in different directions, thereby presenting a colored light spot on at least part of the surface 111.

[0051] Please refer to the following for details: Figure 3 and Figure 4 As can be seen from the entirety of the colorful jewelry 100, at least a portion of its surface 111 appears colored under certain lighting conditions. The colored surfaces 111 appear because white light diffracts through the microgrooves 1121, producing colored light that enters the human eye, resulting in the appearance of colored spots on these surfaces 111. However, the non-colored surfaces 111 do not appear colored because diffraction does not occur at the microgrooves 1121. Rather, the diffracted light generated at these microgrooves 1121 is diffracted in other directions and does not enter the human eye, resulting in the non-colored surfaces 111.

[0052] In addition, from Figure 3 and Figure 4 It can also be seen that, in actual products, the naked eye cannot see the ripples 112 on the surface 111, that is, the naked eye cannot see the micro grooves 1121 and micro ridges 1122 on the surface 111. This is because their sizes are generally in the micrometer or even nanometer level. Only such a small size can ensure that the parallel micro grooves 1121 can form a reflective grating. Therefore, from the naked eye, the surface 111 as a whole appears to be a flat surface. Figure 1 and Figure 2 The corrugations 112 and the micro grooves 1121 and micro ridges 1122 therein are shown for the convenience of explanation only. These structural features cannot be seen in the actual product.

[0053] Please see further Figure 5 The figure shows a magnified portion of the colorful jewelry 100 under an electron microscope. It can be seen from the figure that since the micro grooves 1121 and micro convex strips 1122 in the corrugations 112 are too small, even under an electron microscope, only some horizontal strips in the corrugations 112 can be vaguely seen. These horizontal strips are actually the micro grooves 1121 and micro convex strips 1122.

[0054] For a reflective grating formed by multiple parallel microgrooves 1121, the edge of each microgroove 1121 acts as a secondary wave source to reflect a wavelet (light diffraction). The wavelets reflected by multiple microgrooves 1121 superimpose on each other during propagation (light interference), ultimately causing light of different wavelengths (i.e., light of different colors) to diffract in different directions, resulting in the surface 111 appearing colorful. This reflective grating satisfies the grating equation:

[0055]

[0056] in, d is the grating constant, i.e. the spacing of the micro grooves 1121, corresponding to Figure 2 The vertical distance between the lowest points of two adjacent micro grooves 1121; α is the angle of incidence; β is the diffraction angle; m is the diffraction order; λ is the wavelength of light.

[0057] In order to make the surface 111 appear colorful, it is necessary to ensure that the difference in diffraction angles of different wavelengths is as large as possible. According to formula (1), for the same order m , wavelength difference Δ λ The corresponding diffraction angle difference Δ β for:

[0058]

[0059] Based on formula (2), it can be concluded that d The smaller the ∆ β The larger the value, the stronger the dispersion, and the more obvious the color produced on the surface 111 of the precious metal body 110. d Cannot be less than λ , otherwise the higher-order diffraction will disappear.

[0060] The wavelength range of visible light is roughly 380nm-750nm. d and ∆β relationship, and d The influence of the size of the processing difficulty can be d Set to any value within the range of 0.5μm (500nm) -3μm, after practical verification, d Within this range, not only can the corrugation 112 be effectively processed, but also the colorful jewelry 100 can be processed to show color under natural light. d It is preferably set to 0.5 μm-1 μm. This range can make the color presented on the surface of the colorful jewelry 100 more obvious and the jewelry more beautiful.

[0061] Multiple surfaces 111 that are angled to each other can ensure that no matter from what angle the light shines on the precious metal body 110, and no matter from what angle the human eye observes the precious metal body 110, there can basically be some surfaces 111 that reflect and diffract the colored light so that it enters the human eye, ensuring that the user can effectively observe the colorful appearance of the colorful jewelry 100.

[0062] Please refer again Figure 1 A V-shaped groove 113 can be opened on at least one side of the precious metal body 110. The V-shaped groove 113 is strip-shaped as a whole. The inner wall of the V-shaped groove 113 forms the above-mentioned surface 111. A plurality of micro grooves 1121 and a plurality of micro convex strips 1122 are arranged along the extension direction of the V-shaped groove 113.

[0063] The V-shaped groove 113 can be provided in one piece or in a similar manner. Figure 1 As shown in FIG, multiple V-shaped grooves 113 may be formed. Figure 1 In addition, two adjacent V-shaped grooves 113 can be arranged in a single direction. Figure 1 The phases shown in FIG are continuous, but they can also have certain intervals.

[0064] The main purpose of providing the V-groove 113 is to enable the formation of multiple surfaces 111 facing in different directions on the precious metal body 110, while facilitating processing. Specifically, a tool with a V-shaped cutter head can be used to make a single pass on the precious metal blank to turn out a V-groove 113, or a tool with an angled cutter head can be used to make two passes on the precious metal blank to turn out a V-groove 113. Regardless of the processing method, the V-groove 113 can be efficiently processed.

[0065] In order to further enhance the beauty of the colorful jewelry 100, Figure 1 As shown in , the colorful jewelry 100 further includes a precious metal wire 120, which is fixedly connected to both ends of the V-shaped groove 113 and arched compared to the V-shaped groove 113. Specifically, the precious metal wire 120 can be fixedly connected to the precious metal body 110 by welding.

[0066] After the arched precious metal wires 120 are connected to both ends of the V-shaped groove 113, the overall three-dimensional effect of the colorful jewelry 100 can be increased. On this basis, combined with the color produced by the surface 111 under light, the colorful jewelry 100 can have a good aesthetic effect.

[0067] Furthermore, if Figure 1As shown, the precious metal wire 120 may be provided with decorative patterns 121. The decorative patterns 121 may be formed by cutting or other processing methods. The decorative patterns may be intricate lines or patterns, and are not limited to these. The provision of decorative patterns 121 on the precious metal wire 120 further enhances the aesthetics of the colorful jewelry 100.

The precious metal body 110 can also be a sector as shown in the figure, of course, it can also be a partial ring in its embodiment. Whether it is a sector or a partial ring, it has radial and circumferential directions. The radial and circumferential directions refer to the diameter direction and circumferential direction of the complete circle where the sector or partial ring is located. The V-shaped groove 113 includes multiple, Figure 9 In the figure, the lowest part of the V-grooves 113 is also blocked by the precious metal wire 120. A plurality of V-grooves 113 are radially stacked to form multiple layers, and the V-grooves 113 of each layer are arranged circumferentially. In order to further enhance the aesthetics, the V-grooves 113 of each layer can also be spaced apart as shown in FIG. Figure 9 As shown in FIG, the precious metal body 110 is divided by an arc-shaped precious metal wire 120 . Here, the arc-shaped precious metal wire 120 can be arched relative to the plane where the precious metal body 110 is located, or can be completely attached to the precious metal body 110 .
