Description

Technical Field

[0001] This utility model relates to the field of computer peripheral technology, and in particular to a keyboard. Background Technology

[0002] In existing keyboard manufacturing processes, the patterns and lettering on the keyboard casing are usually fixed during production. To achieve a backlit effect displaying a specific pattern, it is generally achieved by pre-designing a mold and reserving a light-transmitting area in the corresponding position. Once the keyboard is produced, its backlit pattern cannot be changed, making it impossible to meet users' needs for customizing the backlit pattern according to personal preferences or different usage scenarios. Moreover, for some keyboards with backlit patterns, if the pattern is damaged or the user wants to change the pattern, often the entire casing must be replaced, resulting in wasted resources and increased operating costs.

[0003] In summary, existing keyboards generally suffer from problems such as uncustomizable backlight patterns, inflexible changes, and difficulty in repair. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a keyboard that allows users to customize the light-transmitting pattern and to easily repair or re-engrave the pattern.

[0008] Preferably, the other sidewalls include a second sidewall, a third sidewall, and a fourth sidewall, wherein the second sidewall and the third sidewall are adjacent to the first sidewall, and the fourth sidewall is opposite to the first sidewall.

[0009] Preferably, the first light-transmitting layer is injection molded from a transparent or semi-transparent material, and the first opaque coating is a solid-color matte UV coating.

[0010] Preferably, the transparent material is transparent ABS or transparent PC.

[0011] Preferably, the second, third, and fourth sidewalls are all injection molded from black plastic.

[0012] Preferably, the second sidewall, the third sidewall, and the fourth sidewall each include a second light-transmitting layer and a second opaque coating. The second light-transmitting layer is made of a transparent material or is made of a semi-transparent material by injection molding, and the second opaque coating is formed on the surface of the second light-transmitting layer.

[0013] Preferably, the second opaque coating is a solid black coating.

[0014] Preferably, the keyboard casing includes a first sidewall, a second sidewall adjacent to the first sidewall, a third sidewall adjacent to the first sidewall, and a fourth sidewall opposite to the first sidewall. The first sidewall and the fourth sidewall each include a first light-transmitting layer and a first opaque coating. The first opaque coating is formed on the surface of the first light-transmitting layer. The second sidewall and the third sidewall are both opaque structures.

[0024] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] This utility model provides a keyboard. For example... Figure 1-3 As shown, in one embodiment of this utility model, the keyboard includes a keyboard shell, with keys 50 on the top of the keyboard shell and a light source 60 inside the keyboard shell. The keyboard shell includes a first sidewall 10, a second sidewall 20, a third sidewall 30, and a fourth sidewall 40. The second sidewall 20 and the third sidewall 30 are adjacent to the first sidewall 10, and the fourth sidewall 40 is opposite to the first sidewall 10. The first sidewall 10 includes a first light-transmitting layer 11 and a first opaque coating 12, with the first opaque coating 12 formed on the surface of the first light-transmitting layer 11. The first opaque coating 12 can be engraved and can be repeatedly coated.

[0026] In this embodiment, the first light-transmitting layer 11 of the first sidewall 10 is injection molded. Specifically, transparent ABS plastic granules are heated to a molten state and injected into the mold according to the mold shape designed according to the shape of the first light-transmitting layer 11. After processes such as pressure holding and cooling, the entire first light-transmitting layer 11 is formed, ensuring the dimensional accuracy and structural integrity of each part of the first light-transmitting layer 11. The first light-transmitting layer 11 of the first sidewall 10 uses uncolored transparent ABS material during injection molding to ensure its transparency so that subsequent light sources can pass through. Of course, in other embodiments, other transparent materials such as transparent PC material, or semi-transparent materials such as translucent PC material or translucent ABS material, can also be used to injection mold the first light-transmitting layer 11.

[0027] In this embodiment, the first opaque coating 12 is a solid-color matte UV coating. Specifically, after the first translucent layer 11 is injection molded, a professional coating equipment is used to uniformly coat the pre-mixed solid-color matte UV coating onto the first translucent layer 11. During the coating process, the solid-color matte UV coating is controlled by a specific process to form a uniform, smooth, and moderately thick coating. Subsequently, the coated first sidewall 10 is placed under a UV curing device, and ultraviolet light is used to quickly cure the coating, forming a robust solid-color matte UV coating with low gloss and a delicate feel. Users can remove the solid-color matte UV coating of the first sidewall 10 as needed by carving, carving out various patterns, words, and other content. The light source 60 below the first sidewall 10 can illuminate the area after the coating has been carved away, displaying the carved patterns, words, or other specified translucent content. When users want to recarve a translucent pattern, they only need to repaint the original carved area with a UV pen to recarve. Of course, in other embodiments, the first opaque coating 12 may also be a coating of a corresponding color formed by spraying different colored paints, such as a black coating, a gray coating, etc.

[0028] The top, bottom, and other sidewalls (second sidewall 20, third sidewall 30, and fourth sidewall 40) of the keyboard casing are all opaque structures, which can achieve a certain light-focusing effect and enhance the effect of the light-transmitting pattern. In this embodiment, the top, bottom, and second sidewalls 20, 30, and 40 of the keyboard casing each include a second light-transmitting layer and a second opaque coating, with the second opaque coating formed on the surface of the second light-transmitting layer. The second light-transmitting layer is made of a transparent or semi-transparent material and is injection molded. The second light-transmitting layer of the top, bottom, and second sidewalls 20, 30, and 40 of the keyboard casing, as well as the first light-transmitting layer 11 of the first sidewall 10, are integrally molded using an injection molding process. Specifically, according to the mold shape designed for the keyboard shell, transparent ABS plastic granules are heated to a molten state and injected into the mold. After processes such as pressure holding and cooling, the entire keyboard shell body (including the top, bottom, second sidewall 20, third sidewall 30, fourth sidewall 40 second light-transmitting layer, and first light-transmitting layer 11 of the first sidewall 10) is formed, ensuring the dimensional accuracy and structural integrity of each part of the keyboard shell body. Of course, in other embodiments, other transparent materials such as transparent PC material, or semi-transparent materials such as translucent PC material or translucent ABS material, can also be used to injection mold the keyboard shell body. The second opaque coating is a solid black coating. Specifically, after the keyboard shell body is injection molded, black paint is sprayed onto the surface of the second light-transmitting layer of the top, bottom, second sidewall 20, third sidewall 30, and fourth sidewall 40 of the keyboard shell, thereby forming a solid black coating on the surface of the second light-transmitting layer of the top, bottom, second sidewall 20, third sidewall 30, and fourth sidewall 40 of the keyboard shell, so that the surface of the top, bottom, second sidewall 20, third sidewall 30, and fourth sidewall 40 of the keyboard shell presents a solid black effect, which is not easy to fade or wear. It should be noted that in other embodiments, the bottom of the keyboard shell can also be a light-transmitting structure, that is, the top, bottom and other side walls (second side wall 20, third side wall 30, fourth side wall 40) of the keyboard shell are all opaque structures, and the bottom of the keyboard shell is a light-transmitting structure. After the keyboard shell body is injection molded, black paint is sprayed only on the surface of the second light-transmitting layer of the top, second side wall 20, third side wall 30 and fourth side wall 40 of the keyboard shell to form a solid black coating, and the surface of the second light-transmitting layer of the bottom of the keyboard shell is not sprayed with black paint.

[0029] In this embodiment, the keyboard's first sidewall 10 includes a first light-transmitting layer 11 and a first opaque coating 12. The first opaque coating 12 is a solid-color matte UV coating, allowing users to engrave different light-transmitting patterns onto it according to their preferences, satisfying personalized usage needs. Names, symbols, and patterns can all be easily engraved, enhancing the product's flexibility and appeal compared to traditional keyboards with fixed light-transmitting patterns. Furthermore, the keyboard's light-transmitting pattern can be easily repaired if damaged, by reapplying the coating with a UV pen and then re-engraving. Users can also periodically update the pattern, extending the keyboard's lifespan and reducing the cost of replacements due to pattern issues, thus minimizing resource waste. In addition, the top, bottom, second sidewall 20, third sidewall 30, and fourth sidewall 40 of the keyboard casing are all opaque structures, providing a certain light-focusing effect and enhancing the effect of the light-transmitting pattern.

[0030] See you again Figure 1-3 In another embodiment of the present invention, the keyboard includes a keyboard shell, with a key 50 on the top of the keyboard shell and a light source 60 inside the keyboard shell. The keyboard shell includes a first sidewall 10, a second sidewall 20, a third sidewall 30 and a fourth sidewall 40, wherein the second sidewall 20 and the third sidewall 30 are adjacent to the first sidewall 10, and the fourth sidewall 40 is opposite to the first sidewall 10. The first sidewall 10 includes a first light-transmitting layer 11 and a first opaque coating 12, wherein the first opaque coating 12 is formed on the surface of the first light-transmitting layer 11.

After processes such as pressure holding and cooling, the entire first light-transmitting layer 11 is formed, ensuring the dimensional accuracy and structural integrity of each part of the first light-transmitting layer 11. The first light-transmitting layer 11 of the first sidewall 10 uses uncolored transparent ABS material during injection molding to ensure its transparency so that subsequent light sources can pass through. Of course, in other embodiments, other transparent materials such as transparent PC material, or semi-transparent materials such as translucent PC material or translucent ABS material, can also be used to injection mold the first light-transmitting layer 11.

[0032] In this embodiment, the first opaque coating 12 is a solid-color matte UV coating. Specifically, after the first translucent layer 11 is injection molded, a professional coating equipment is used to uniformly coat the pre-mixed solid-color matte UV coating onto the first translucent layer 11. During the coating process, the solid-color matte UV coating is controlled by a specific process to form a uniform, smooth, and moderately thick coating. Subsequently, the coated first sidewall 10 is placed under a UV curing device, and ultraviolet light is used to quickly cure the coating, forming a robust solid-color matte UV coating with low gloss and a delicate feel. Users can remove the solid-color matte UV coating of the first sidewall 10 as needed by carving, carving out various patterns, words, and other content. The light source 60 below the first sidewall 10 can illuminate the area after the coating has been carved away, displaying the carved patterns, words, or other specified translucent content. When users want to recarve a translucent pattern, they only need to repaint the original carved area with a UV pen to recarve. Of course, in other embodiments, the first opaque coating 12 may also be a coating of a corresponding color formed by spraying different colored paints, such as a black coating, a gray coating, etc.

[0033] The top, bottom, and other sidewalls (second sidewall 20, third sidewall 30, and fourth sidewall 40) of the keyboard shell are all opaque, which can achieve a certain light-focusing effect and enhance the effect of the light-transmitting pattern. In this embodiment, the top, bottom, and other sidewalls (second sidewall 20, third sidewall 30, and fourth sidewall 40) of the keyboard shell are all injection molded from black plastic. Specifically, according to the mold shape designed according to the shape of the top, bottom, and other sidewalls (second sidewall 20, third sidewall 30, and fourth sidewall 40) of the keyboard shell, black pigment and ABS plastic particles are heated to a molten state and injected into the mold. After pressure holding, cooling, and other processes, the top, bottom, and other sidewalls (second sidewall 20, third sidewall 30, and fourth sidewall 40) of the molded keyboard shell present a solid black effect, which is tightly bonded to the first sidewall 10 and is not easy to fade or wear.

[0034] In this embodiment, the keyboard's first sidewall 10 includes a first light-transmitting layer 11 and a first opaque coating 12. The first opaque coating 12 is a solid-color matte UV coating, allowing users to engrave different light-transmitting patterns onto it according to their preferences, satisfying personalized usage needs. Names, symbols, and patterns can all be easily engraved, enhancing the product's flexibility and appeal compared to traditional keyboards with fixed light-transmitting patterns.

Additionally, the second sidewall 20, third sidewall 30, and fourth sidewall 40 are all opaque structures, providing a certain light-focusing effect and enhancing the effect of the light-transmitting pattern.

[0042] In this embodiment, the first light-transmitting layer 11 of the first sidewall 10 and the fourth sidewall 40 is injection molded. Specifically, transparent ABS plastic granules are heated to a molten state and injected into the mold according to the mold shape designed according to the shape of the first light-transmitting layer 11.

The light source 60 below the first sidewall 10 and the fourth sidewall 40 can illuminate the area after the coating has been carved away, presenting the patterns, words, or other specified translucent content carved by the user. When the user wants to recarve a translucent pattern, they only need to repaint the original carved area with a UV pen to recarve. Of course, in other embodiments, the first opaque coating 12 may also be a coating of a corresponding color formed by spraying different colored paints, such as a black coating, a gray coating, etc.

[0044] Both the second sidewall 20 and the third sidewall 30 are opaque structures, which can achieve a certain light-focusing effect and enhance the effect of the light-transmitting pattern. In this embodiment, both the second sidewall 20 and the third sidewall 30 include a second light-transmitting layer and a second opaque coating, with the second opaque coating formed on the surface of the second light-transmitting layer. The second light-transmitting layer is made of transparent or semi-transparent material and is injection molded. Specifically, the second light-transmitting layers of the second sidewall 20 and the third sidewall 30, as well as the first light-transmitting layers 11 of the first sidewall 10 and the fourth sidewall 40, are integrally molded using an injection molding process. Specifically, according to the mold shape designed for the keyboard shell, transparent ABS plastic granules are heated to a molten state and injected into the mold. After processes such as pressure holding and cooling, the entire keyboard shell body (including the second light-transmitting layers of the second sidewall 20 and the third sidewall 30, as well as the first light-transmitting layers 11 of the first sidewall 10 and the fourth sidewall 40) is formed, ensuring the dimensional accuracy and structural integrity of each part of the keyboard shell body. Of course, in other embodiments, other transparent materials such as transparent PC material, or semi-transparent materials such as translucent PC material or translucent ABS material can be used to injection mold the keyboard shell body. The second opaque coating is a solid black coating. Specifically, after the keyboard shell body is injection molded, black paint is sprayed onto the second light-transmitting layer surfaces of the second sidewall 20 and the third sidewall 30, thereby forming a solid black coating on the second light-transmitting layer surfaces of the second sidewall 20 and the third sidewall 30, so that the surfaces of the second sidewall 20 and the third sidewall 30 present a solid black effect, which is not easy to fade or wear.

[0045] like Figure 4 As shown, in this embodiment, the key 50 includes a keycap. The top of the keycap includes a third light-transmitting layer 51 and a third opaque coating 52. The third opaque coating 52 is formed on the surface of the third light-transmitting layer 51, and the four sidewalls 53 of the keycap are all opaque. Specifically, according to the mold shape designed for keycap formation, transparent ABS plastic granules are heated to a molten state and injected into the mold. After pressure holding, cooling, and other processes, the entire keycap (including the third light-transmitting layer 51 on the top of the keycap and the four sidewalls 53 of the keycap) is formed. Of course, in other embodiments, other transparent materials such as transparent PC materials, or semi-transparent materials such as translucent PC materials or translucent ABS materials, can also be used to injection mold the keycap. After the keycaps are injection molded, a pre-mixed solid-color matte UV coating is evenly applied to the surface of the third translucent layer 51 using professional coating equipment. During the coating process, the solid-color matte UV coating is controlled by specific techniques to form a uniform, smooth, and moderately thick coating, namely the third opaque coating 52. Subsequently, the coated keycaps are placed under a UV curing device, where ultraviolet light rapidly cures the coating, forming a robust solid-color matte UV coating with low gloss and a smooth feel. After injection molding, black coating is sprayed onto the four sidewalls 53 of the keycaps, forming a solid black coating on each of the four sidewalls 53, giving the four sidewalls a solid black effect that is resistant to fading or wear.

[0046] In this embodiment, the keyboard's first sidewall 10 and fourth sidewall 40 include a first light-transmitting layer 11 and a first opaque coating 12. The first opaque coating 12 is a solid-color matte UV coating, allowing users to engrave different light-transmitting patterns onto it according to their preferences, satisfying personalized usage needs. Names, symbols, and patterns can all be easily engraved, enhancing the product's flexibility and appeal compared to traditional keyboards with fixed light-transmitting patterns. Furthermore, the keyboard's light-transmitting pattern can be easily repaired after damage by reapplying the coating with a UV pen and re-engraving. Users can also periodically update the pattern, extending the keyboard's lifespan and reducing the cost of replacements due to pattern issues, thus minimizing resource waste. Additionally, the second sidewall 20 and third sidewall 30 are both opaque structures, providing a certain light-focusing effect and enhancing the effect of the light-transmitting pattern. Finally, the top of the keycap of key 50 includes a third light-transmitting layer 51 and a third opaque coating layer 52. The third opaque coating layer 52 is a solid-color matte UV coating. Users can engrave different light-transmitting patterns on the third opaque coating layer 52 according to their own preferences to meet personalized usage needs. Whether it is a name, symbol, or pattern, it can be easily engraved. Compared with traditional keyboard keys with fixed light-transmitting patterns, this improves the flexibility and fun of the product. Moreover, the light-transmitting pattern of the keyboard key can be easily repaired after damage by re-coating the paint with a UV pen, or users can update the pattern regularly, extending the service life of the keyboard key, reducing the cost of replacement due to pattern problems, and reducing resource waste.
