Description

Technical Field

[0001] The present application relates to the field of computer keyboards, and more particularly to a light-emitting keyboard and a lighting effect control method. Background Art

[0002] Common keycaps on existing keyboards are ordinary two-color keycaps. These keycaps cannot effectively transmit light when used with illuminated keyboards. Furthermore, partially transparent keycaps lack a relatively complete light-transmitting component. In particular, keycaps with partially transparent side characters cannot support more advanced lighting effects, resulting in poor light transmission and uneven light transmission through cracks. This can easily lead to blurred and unclear light from the entire keycap, seriously affecting the keyboard's aesthetics.

[0003] In addition, the height distribution of existing keycaps is unreasonable and cannot fully meet the needs of ergonomics. The users need to exert a lot of pressure during typing, which can easily lead to fatigue and affect the fluency of the application.

[0004] At the same time, different types of key switches cannot effectively transmit light when used in conjunction with luminous keyboards. From the structural composition of the mechanical switch, its own copper sheet structure will block the light on the base shell, making it impossible to fully transmit light.

[0005] In the structural form of the magnetic axis, some magnetic axes will have a light-transmitting hole on the upper cover of the key axis to let light in. However, most magnetic axes only have a single-side opening. When multiple light points are arranged around each key on the PCB board of the base shell, there is also a defect of blocking light, and it cannot support the coordinated application of multiple LED light points.

[0006] During the use of luminous keyboards, traditional lighting control usually relies on physical connections or fixed configurations, making it difficult to achieve remote control and expansion of personalized lighting effects. Summary of the Invention

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0064] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0065] The luminous keyboard in the present application mainly changes the structure of the key shaft 10 keycap 100 to enhance the light transmittance of the key shaft 10 keycap 100, while improving the lighting effect of the overall structure of the existing luminous keyboard. At the same time, through the lighting effect control method of the luminous keyboard in the present invention, combined with multiple LED light points, a unique visual effect is formed, thereby improving the product's aesthetics and user experience.

[0066] See also Figure 1 , and combined with Figure 2-Figure 10 The luminous keyboard of the present invention has a main structure including a keyboard housing 1, a PCB board 2 is arranged inside the keyboard housing 1, and multiple groups of LED lights 3 are arranged on the PCB board 2, and each group of LED lights 3 corresponds to each group of key shafts 10 and keycaps 100.

[0067] Each group of the LED lights 3 includes a plurality of LED light points, and the plurality of LED light points are arranged on the circumferential periphery of the key shaft 10 .

[0068] By setting up multiple LED light points around each set of key shafts 10 and keycaps 100 on the PCB board 2, it is possible to improve the lighting effect of existing single LED light points. The light points can transmit light outward from the gaps in the keycaps 100, forming a soft "suspended halo", as if the keycaps 100 are floating above the light curtain, enhancing the three-dimensional and technological sense of the keyboard. For example, in gaming mode, the halo can diffuse outward as skills are released, simulating the effect of energy fluctuations. By enhancing the light transmittance of the key shafts 10 and keycaps 100, the transparent areas allow surrounding light to pass through, forming a light refraction or scattering effect, increasing the visual layering, suitable for users with a strong sense of technology.

[0069] Through light points of different colors, dynamic lighting effects can be formed, such as color alternation or gradient, providing an artistic feel, which is suitable for users who like dynamic effects.

[0070] From the perspective of improvement of the keycap 100, by setting the top shell 110 to an opaque solid color top shell 110, setting the key shaft base 12 to an opaque double-layer key shaft base 12, and combining the middle shell 120 in the form of a transparent shell made of transparent material, it can be beneficial to the scattering of the color light in the luminous keyboard from the middle shell 120, improve the light color rendering state of the existing keyboard keycap 100, make the keycap 100 emit light more clearly, and thereby reduce the light blur of the overall luminous keyboard.

[0071] The keycap 100 is a two-color injection-molded structure, which can facilitate secondary molding of the keycap 100 during the processing process, so that the transparent part and the solid color shielding part of the keycap 100 can be separately formed in each injection molding process.

[0072] The key shaft base 12 includes a transparent layer 131 located on the inner side and a solid color layer 132 located on the outer side. The transparent layer 131 and the solid color layer 132 can be formed separately during the secondary molding process, thereby reducing the processing difficulty of the keycap 100 and ensuring the structural strength of the key shaft base 12.

[0073] By setting the keycaps 100 in different horizontal rows to different heights in the vertical direction, and distributing the heights of the keycaps 100 in different horizontal rows in an upward, downward, and upward distribution trend, ergonomic setting angles can be fully taken into account, thereby reducing the movement pressure and keystroke pressure required by the user during typing, thereby improving fluency.

[0074] The space key includes an independent domed top surface, which can fully meet the user's thumb tapping during typing, and thus fully consider the ergonomic characteristics of all keycaps 100 in the keyboard typing area, greatly reducing fatigue.

[0075] From the perspective of the improvement of the key shaft 10, through the translucent top cover 11, transparent key shaft base 12 and transparent axis 13 included in the keyboard key shaft 10, the light of the LED light point of the key shaft base 12 shell can be fully transmitted, while presenting a primary color fog-transparent effect, thereby improving the light transmittance and aesthetics of the key shaft 10, and at the same time, the light can be transmitted to the keycap 100 through the key shaft 10, thereby improving the quality of the luminous keyboard.

[0076] The translucent upper cover 11 , the transparent key shaft base 12 and the transparent axis 13 are all axially symmetrical structures, which can form a symmetrical integrated structure of the keyboard key shaft 10 , ensuring that the keyboard key shaft 10 has uniform light transmission from top to bottom.

[0077] The transparent axis 13 includes a cross key axis 13 a for the keycap 100 to be buckled and installed, providing a structural foundation for the installation of the keycap 100 and at the same time being able to achieve complete light transmission and transmit light to the keycap 100 .

[0078] The translucent top cover 11 and the transparent key shaft base 12 are snap-fitted together, which can facilitate the replacement of internal components. By setting the cross key shaft 13a in the center of the translucent top cover 11 and the transparent key shaft base 12, combined with multiple LED light points set on the periphery of the keyboard key shaft 10, the obstruction of light by some opaque structures can be reduced, ensuring the light transmission effect.

[0079] The keyboard key shaft 10 in the present invention is not limited by the form of the key shaft 10, including a mechanical shaft or a magnetic shaft, and can simultaneously meet the light transmission requirements of keyboard key shafts 10 of different forms.

[0080] The keyboard key shaft 10 in the present invention can reduce light scattering loss, optimize the uniformity and reflection path of the light, and the symmetrical integrated structure can make the light form diffuse reflection inside the shaft, eliminating the "light spot" phenomenon of the traditional shaft, achieving a crystal-like light-transmitting texture, and greatly improving the light effect of the keyboard key shaft 10.

[0081] The PCB board 2 is provided with a keyboard main chip and a lighting effect slave chip. The lighting effect slave chip includes an RGB lighting control chip. The RGB lighting control chip is communicatively connected to the keyboard main chip and is equipped with a Bluetooth module.

[0082] Through the keyboard main chip and the lighting effect slave chip in the present invention, a structural foundation can be established for the lighting effect control of the luminous keyboard. At the same time, the lighting effect slave chip form of the RGB lighting control chip can be beneficial to the control of the lighting effect of the luminous keyboard. Combined with the communication connection between the RGB lighting control chip and the keyboard main chip and the RGB lighting control chip is equipped with a Bluetooth module, it can provide space for communication data connection for subsequent wireless control of the computer and mobile terminal.

[0083] From a specific structural perspective, first of all, from the perspective of the improvement of the key shaft 10, by making necessary improvements to the structure of the keyboard key shaft 10, the visual sense of the existing luminous keyboard can be improved, and the disassembly and installation of the keyboard key shaft 10 can be made more convenient, which is conducive to replacement on the key shaft base 12 shell.

[0084] See also Figure 4-Figure 6 The keyboard key shaft 10 in the present invention has a main structure including a translucent upper cover 11, a transparent key shaft base 12 and a transparent axis 13. From the perspective of improving the lighting effect, the light source located on the key shaft base 12 shell can be transmitted through the transparent key shaft base 12 and the transparent axis 13. Combined with the translucent upper cover 11, a primary color fog-transparent lighting effect can be formed, thereby improving the light transmittance and aesthetics of the axis.

[0085] The translucent top cover 11, the transparent key shaft base 12 and the transparent axis 13 are all axially symmetrical structures. Specifically, from the direction of use, the translucent top cover 11, the transparent key shaft base 12 and the transparent axis 13 are all horizontally axially symmetrical and front-to-back axially symmetrical structures. Through this setting method, an integrated light-guiding structure symmetrical to the keyboard key shaft 10 can be formed, which can ensure that light is evenly transmitted from the front and rear parts of the shaft body, thereby avoiding the problem of poor visual effects caused by uneven light in the existing technology.

[0086] Compared with the existing traditional key shaft 10, the keyboard key shaft 10 in the present invention makes the light effect of each key position fuller and more uniform, thereby improving the overall visual beauty of the keyboard.

[0087] The transparent axis 13 includes a cross key axis 13a for the keycap 100 to be installed. The cross key axis 13a included in the transparent axis 13 provides a structural basis for the installation of the keycap 100. More importantly, it can allow light to pass through completely, so that the keycap 100 connected and installed on the cross key axis 13a can be rendered by light, thereby improving the rendering light effect of the keyboard.

[0088] The translucent top cover 11 and the transparent key shaft base 12 are snap-fitted together, which enables the detachable disassembly of the fog-transparent structure and the light-transmitting structure. The transparent top cover 11 can be replaced on the transparent key shaft base 12 according to different lighting effect requirements, thereby creating space for personalized lighting effect settings.

[0089] By setting the cross key shaft 13a of the transparent axis 13 in the middle of the translucent upper cover 11 and the transparent key shaft base 12, and combining the extension of the cross key shaft 13a from the translucent upper cover 11, the light from the LED light point at the bottom can be guided out from the middle part of the key shaft 10, ensuring uniform and coordinated light transmission and reducing the obstruction of light by the key shaft 10 structure.

[0090] The key shaft 10 structure of the present invention can be applied in the form of a mechanical shaft, and can also be applied in the form of a magnetic shaft, which can broaden the application scope of the transparent key shaft 10 and achieve improved lighting effects for keyboards with different key shaft 10 forms.

[0091] In response to the specific light-transmitting effects of the different structures mentioned above, the translucent top cover 11, the transparent key shaft base 12 and the transparent axis 13 are all one-piece injection-molded structures, specifically, they are one-piece injection-molded plastic structures. More specifically, in response to the light fog-transmitting effect of the top cover 11, the translucent top cover 11 includes POM material. At the same time, based on the bottom structure of the key shaft 10 and the light transmission requirements of the key shaft 10 to the keycap 100, the transparent key shaft base 12 and the transparent axis 13 include PC material, thereby constituting a key shaft 10 as a whole that can transmit light evenly from top to bottom, making the light effect of the luminous keyboard richer and fuller.

[0092] Based on the basic function of the key switch 10, the transparent axis 13 includes a mounting post 13b for mounting a trigger sensor. The trigger sensor is fixedly connected to the bottom of the mounting post 13b and can move synchronously with the transparent axis 13;

[0093] The mounting post 13b is concentrically arranged with the cross key shaft 13a and is located on the other side of the transparent axis 13 from the cross key shaft 13a. This arrangement, combined with the cross key shaft 13a being positioned in the center of the translucent upper cover 11 and the transparent key shaft base 12, minimizes light obstruction by the trigger sensor.

[0094] In the structural form of the mechanical switch, the trigger sensing member includes a trigger metal sheet installed at the bottom end of the mounting column 13b.

[0095] In the structural form of the magnetic shaft, the trigger induction member includes a magnetic shaft permanent magnet 14 in the form of a circular magnet, and the mounting column 13b includes an open recessed groove at the bottom end, in which the magnet is fixedly mounted.

[0096] Through the above-mentioned arrangement, the light transmission requirements of different key shaft 10 structures can be met, so that the light blocking by the trigger metal sheet or the magnetic axis permanent magnet 14 located in the middle is reduced to a minimum.

[0097] At the same time, in order to ensure the normal reciprocating up and down movement of the key shaft 10, a reset spring 15 is sleeved on the outer side of the mounting column 13b, and the transparent axis 13 includes a limiting shoulder 13c located between the cross key shaft 13a and the mounting column 13b. The top end of the reset spring 15 abuts against the bottom wall of the limiting shoulder 13c, and the bottom end of the reset spring 15 abuts against the bottom wall of the transparent key shaft base 12.

[0098] Furthermore, the transparent key shaft base 12 is provided with a docking sleeve 121 with an open top for the mounting column 13b to movably extend into, the limiting shoulder 13c is an inverted U-shaped plate structure, and the side wall of the U-shaped plate structure is provided with a limiting fin 13d for limiting the transparent axis 13 to abut against the inside of the translucent upper cover 11, the bottom of the reset spring 15 is arranged on the outside of the docking sleeve 121, and the top of the reset spring 15 is arranged on the inner side of the side wall of the U-shaped plate structure.

[0099] Through the above-mentioned setting structure, the normal operating function of the key shaft 10 can be met. It should be pointed out that the above-mentioned different structures are all made of transparent PC material, which can ensure the light transmittance of the axis 13 and the key shaft base 12 to the greatest extent, and reduce the influence of the reset spring 15 and necessary functional components on the light transmittance to a minimum.

[0100] Regarding the detachable relationship between the translucent upper cover 11 and the transparent key shaft base 12 described above, the translucent upper cover 11 is provided with a docking claw 111 for snap-fitting with the transparent key shaft base 12. The docking claw 111 is arranged on the circumference of the translucent upper cover 11. In conjunction with the accompanying drawings, the docking claw 111 includes four arranged at the four corners of the upper cover 11. The corresponding position of the transparent key shaft base 12 is provided with a snap-fit shoulder 122. The snap-fit shoulder 122 is arranged corresponding to the docking claw 111 and is used for the snap-fit connection of the docking claw 111. By snapping the docking claw 111 onto the snap-fit shoulder 122, the detachable connection between the two can be achieved, which is conducive to achieving personalized light effect distribution at different axis positions.

[0101] From the perspective of detachably connecting the key shaft 10 to the keyboard housing 1, based on the connection between the upper cover 11 and the key shaft base 12 by snap-fitting, the translucent upper cover 11 is also provided with a mounting claw 112 for snap-fitting and installing the keyboard key shaft 10 on the keyboard housing 1, and the transparent key shaft base 12 is provided with an avoidance groove 123 for accommodating the installation of the mounting claw 112.

[0102] After the upper cover 11 is buckled with the key shaft base 12, the mounting claw 112 can be accommodated in the avoidance groove 123 on the key shaft base 12, and at the same time, there is a certain amount of elastic deformation space in the avoidance groove 123. The keyboard housing 1 includes a mounting plate for mounting the key shaft 10 as a whole, and a plurality of mounting holes are opened on the mounting plate to ensure that the mounting claw 112 is snap-fitted with the plate body at the mounting hole position.

[0103] In addition to the top cover 11's fit with the mounting plate and mounting holes, the key shaft base 12 also features an elastic snap-fit relationship with the mounting plate and mounting holes to ensure structural stability. Furthermore, the transparent key shaft base 12 also features another set of elastic structures that snap-fit with the top cover 11, in addition to the engaging claws 111.

[0104] Specifically, the transparent key shaft base 12 is also provided with an elastic claw 124, which includes an elastic main claw 124a that can be elastically embedded in the inner side of the translucent upper cover 11. The elastic main claw 124a is arranged between the docking claws 111 and on the other side of the avoidance groove 123. Through the further cooperation between the elastic main claw 124a and the transparent upper cover 11, the cooperation reliability of the key shaft base 12 and the upper cover 11 can be guaranteed.

[0105] At the same time, the elastic claw 124 also includes an elastic auxiliary claw 124b exposed on the translucent upper cover 11 after the translucent upper cover 11 is clamped with the transparent key shaft base 12, and the elastic auxiliary claw 124b can be elastically clamped with the keyboard shell 1, and then can form a matching relationship between the key shaft 10 and the keyboard shell 1 in the circumferential direction, ensuring a stable and reliable connection.

[0106] In the present invention, each group of LED lights 3 includes multiple light points surrounding the circumference of the keyboard key shaft 10. Combined with the symmetrical integrated structure of the keyboard key shaft 10, it ensures that light is evenly transmitted up and down the shaft, thereby making the lighting effect of the keyboard more uniform and layered.

[0107] Secondly, from the perspective of the improvement of the keycap 100, by making necessary improvements to the structure of the keyboard keycap 100, the visual sense of the existing luminous keyboard can be improved, and the key tapping can be made more ergonomic, reducing the pressure of the fingers on the keys, reducing fatigue in use, and improving the smoothness of use.

[0108] See also Figure 7-10 The keyboard keycap 100 of the present invention has a main structure including a keycap body 100. In terms of specific composition, the keycap body 100 includes a top shell 110, an intermediate shell 120 and a keycap base 130. The top shell 110, the intermediate shell 120 and the keycap base 130 are arranged in sequence from top to bottom.

[0109] From the perspective of enabling the keycap 100 to emit light, the middle shell 120 in the present invention includes a transparent shell made of a transparent material. Compared with the existing side-transmitting form, by making the middle shell 120 translucent, an overall aperture of the middle shell 120 can be formed, thereby enhancing the coordination and unity of the overall keyboard lighting and supporting more advanced lighting effects.

[0110] In order to reduce the halo rendering of the luminous background color, the top shell 110 includes an opaque solid color top shell 110, which can shield the light of the middle shell 120 from the top. At the same time, by setting the keycap base 130 to an opaque double-layer keycap base 130, the light can be shielded from the bottom at the lower part of the middle shell 120, thereby ensuring an effective aperture in the middle shell 120 portion of the keycap 100.

[0111] The keycap base 130 includes an opaque double-layer keycap base 130 , which is mainly for the purpose of performing secondary injection molding on the keycap 100 based on the transparent layer 131 and the solid color layer 132 .

[0112] Specifically, the main body of the keycap 100 is a two-color injection molding structure, which includes a transparent layer 131 molded once and a solid color layer 132 molded twice. Based on this, the keycap base 130 includes a transparent layer 131 located on the inner side and a solid color layer 132 located on the outer side, which can form a light shielding effect on the bottom of the intermediate shell 120 and facilitate the processing and molding of the keycap 100.

[0113] During the injection molding process, the transparent layer 131 structure is firstly injection molded, and then the solid color layer 132 structure is injection molded, thereby forming the overall structure of the keycap 100 body.

[0114] Based on the light-emitting structure of the keycap 100 described above, the present invention further makes necessary improvements to the height of the keycap 100 to improve the user's functionality when tapping the keycap 100 .

[0115] Specifically, according to the horizontal layout on the keyboard, the keycaps 100 include keycaps 100 of different horizontal rows at different heights. The keycaps 100 of each horizontal row are maintained at the same height. In the vertical direction, the heights of the keycaps 100 of different horizontal rows show a distribution trend of rising, falling and then rising again. The space key includes an independent dome top surface.

[0116] During specific use, relative to the direction of use of the keyboard, the keyboard body maintains a downward inclination angle of about 14° from back to front. Based on the tilted state of the keyboard body, in the vertical direction of the use direction, the heights of the keycaps 100 in different horizontal rows in the present invention show a distribution trend of rising, falling and then rising again, which can be more in line with the overlapping height of the user's fingers on the keyboard, so that the arc trajectory of the user's fingers can better act on the keycaps 100 of different horizontal row heights. At the same time, on the basis of satisfying the basic tapping function, it can reduce the pressure exerted by the fingers on the keycaps 100. On the one hand, it can improve the fluency during use, and on the other hand, it can reduce fatigue during use.

[0117] Combined with the separate tapping of the space key by the thumb, by setting the space key as an independent dome top surface structure and setting the top of the space key to a top surface structure different from other keycaps 100, the use function of the space key can be independently distinguished, which greatly improves the tapping status of all keycaps 100 of the keyboard as a whole and is more in line with ergonomic requirements.

[0118] With respect to the specific double-color injection molding structure of the keycap 100 body, the keycap 100 body includes a primary injection molding body with a transparent structure and a secondary injection molding body with a solid color structure.

[0119] Specifically, based on the opaque double-layer structure of the keycap base 130, the transparent layer 131 located on the inner side of the keycap base 130, the middle shell 120 with a transparent structure, and the cross key column 150 arranged at the bottom of the middle shell 120 and on the inner side of the keycap base 130 constitute a one-time injection molding body. At the same time, in the keycap 100 form with fonts set, the one-time injection molding body also includes a font structure 140 located on the top of the middle shell 120. Furthermore, the font structure 140 is also a transparent structure that is injection-molded as a whole with the middle shell 120 and the transparent layer 131 of the keycap base 130, and can transmit light on the surface of the solid color top shell 110. Through this setting method, compared with the traditional method of setting fonts on the keycap 100 by printing and coating, on the one hand, the keycap 100 can better cooperate with the light and show a more uniform and delicate light effect. On the other hand, it avoids the problem of blurred or fading characters in the existing keycap 100 during long-term use.

[0120] At the same time, in order to allow the aperture to transmit light only through the middle shell 120, the solid color layer 132 of the keycap base 130 and the top shell 110 constitute a secondary injection molded body, and the solid color layer 132 of the keycap base 130 is used to shield the keycap base 130 from external light, and the top shell 110 is used to shield the top light above the middle shell 120, which can highlight the aperture of the middle shell 120 for transmitting light.

[0121] From the perspective of enhancing the overall structural strength of the keycap 100 and facilitating installation, an engineering step 133 is provided between the intermediate shell 120 and the keycap base 130. With respect to the one-time molding structure described above, in order to facilitate injection molding, the side wall of the intermediate shell 120 and the inner side wall of the transparent layer 131 of the keycap base 130 are an integrally molded structure during a one-time injection molding process. In order to facilitate the molding of the above-mentioned engineering step 133, a secondary injection molded body is located on the outer side of the transparent layer 131 to form the engineering step 133.

[0122] That is to say, during the secondary injection molding process, the outer wall structure of the solid color layer 132 of the keycap base 130 forms a part of the engineering step 133, and the shoulder portion on the outer wall of the solid color layer 132 of the keycap base 130 that intersects with the intermediate shell 120 forms another part of the engineering step 133. Through this setting method, the structural strength of the keycap 100 can be enhanced on the basis of forming the solid color layer 132 of the keycap base 130. At the same time, the solid color engineering step 133 sets off the aperture of the intermediate shell 120, which can avoid the diffusion of the aperture light and fully ensure the uniform and coordinated lighting effect.

[0123] The one-time injection molding body also includes a font structure 140 located at the top of the middle shell 120 and a cross key column 150 located at the bottom of the middle shell 120. The font structure 140 of the keycap 100 and the necessary connection structure can be formed in a one-time injection molding process. By surrounding the solid color layer 132 of the top shell 110 on the outside of the font structure 140, a light-transmitting effect of the font structure 140 on the top shell 110 can be formed, which is beneficial for recognition during typing. At the same time, the font structure 140 of the one-time injection molding body can reduce wear during long-term use and extend the service life.

[0124] To facilitate tapping of the keycap 100 , the keycap 100 includes a curved fitting surface 160 at the top for fingertips to press and contact, and the font structure 140 includes a font top surface that can transmit light through the curved fitting surface 160 .

[0125] Specifically, the top surface of the font structure 140 is exposed on the top shell 110, and in order to enable the top surface of the top shell 110 and the top surface of the font structure 140 to form a relatively regular arc-shaped fitting surface 160, the exposed top surface of the font structure 140 and the top surface of the top shell 110 are smoothly transitioned and flush. Through this setting method, the exposed top surface of the font structure 140 and the top surface of the top shell 110 can jointly form the arc-shaped fitting surface 160, making the fitting and pressing of the top of the keycap 100 more comfortable.

[0126] On the basis of the light-transmitting structure described above, in order to improve the smoothness of the keycap 100 in use on the keyboard and make the keycap 100 more ergonomic in terms of tapping, the height of the keycaps 100 of different horizontal rows of keycaps 100 are set specifically when the keyboard body is in an inclined usage state.

[0127] Specifically, the keycaps 100 include six rows arranged horizontally. From the direction of use of the keyboard, the side facing the user is the front side, and the side away from the user is the back side. The keycaps 100 include a first height, a second height, a third height, a fourth height and a fifth height arranged in sequence from front to back. The keycaps 100 in the first and second horizontal rows have the same height and are the first height in common. The third to sixth horizontal rows are the second to fifth heights in sequence.

[0128] Through the above-mentioned setting form, the fifth layer of keycap 100 height can be additionally set on the basis of the existing four common setting heights, so as to broaden the use status of different horizontal row keycap 100 heights.

[0129] Regarding the downwardly extending tilted state of the keyboard body from back to front, and the user's fingers resting on the third horizontal row at the second height during use, by making the second height higher than the first height, combined with the downwardly extending tilted state of the keyboard body, the keycaps 100 in the two front horizontal rows and the keycaps 100 in the third horizontal row can be maintained in the same tilted extension state relative to each other, and at the same time, it is convenient for the fingers to operate on the keyboard in an arc trajectory with the overlapping position of the keycaps 100 in the third horizontal row as the reference point.

[0130] The third height is the smallest among all keycaps 100 , and can offset the height difference of the fourth row of keycaps 100 when the keyboard body is tilted. At the same time, it can reduce the tapping pressure and application fatigue in combination with the higher application frequency of the fourth row of keycaps 100 .

[0131] The fourth height of the fifth row of keycaps 100 is greater than the third height of the fourth row of keycaps 100 and less than the fifth height of the sixth row of keycaps 100. Furthermore, by making the fifth height of the sixth row of keycaps 100 greater than the fourth height of the fifth row of keycaps 100 and less than the first height of the two front rows of keycaps 100, it is possible to facilitate light tapping of the less frequently used fifth row of keycaps 100 and the sixth row of keycaps 100, thereby greatly improving the coordination of tapping of all the keycaps 100 on the keyboard body.

[0132] Based on the characteristics of tapping the space key with the thumb, the height of the keycap 100 of the space key is the same as the height of the keycaps 100 in the same horizontal row. A chamfer 170 tilted downward and backward is provided on the top of the space key. By setting the chamfer 170 on the rear edge of the space key in the length direction, it is conducive to the thumb tapping toward the rear side of the user. Combined with the structure of the independent arched top surface of the space key, the comfortable contact between the thumb and the space key can be guaranteed.

[0133] The above-mentioned keyboard keycap 100 can improve the light transmission effect of the keycap 100 and can better meet the needs of ergonomics based on the trajectory of the finger arc.

[0134] Each group of LED lights 3 includes multiple LED light points, and multiple LED light points are arranged on the circumference of the key shaft 10. Specifically, in the form of a mechanical key shaft 10, four LED lights 3 of 1206 or other specifications are arranged on the circumference of the key shaft 10 to cover the peripheral area of the key shaft 10, which not only ensures the feel but also presents new lighting effects. At the same time, in the form of a magnetic key shaft 10, two to four LED lights 3 of 1206 or other specifications are arranged at the four corners with the Hall element in the center, which can present more lighting control effects compared to the existing traditional single lamp beads.

[0135] Based on the structure of the luminous keyboard described above, the present invention also provides a lighting effect control method for the luminous keyboard, specifically, on the basis of establishing a communication data connection relationship between different structures, the lighting effect is controlled simultaneously through the computer and mobile terminals.

[0136] Multiple LEDs can be configured to adjust their brightness and color, creating a variety of lighting effects. A modular design supports multiple LED layouts and flexible lighting control. Using an I2C or SPI interface, individual lighting effects for different keys can be adjusted, improving programmability.

[0137] The even distribution of LED lights 3 makes the lighting effect of each key more obvious and consistent, providing users with a smoother and more efficient lighting experience.

[0138] The PCB board 2 in this application supports the layout and control of more LED lights 3, allowing the keyboard to achieve a variety of complex lighting effects. This allows users to customize more lighting schemes according to their needs, enhancing visual expression.

[0139] The luminous keyboard of the present invention can provide a more comfortable typing experience, and can also attract users who have high requirements for visual effects through lighting effects and customization options. It not only improves the functionality of the keyboard, but also enhances its aesthetic performance, making it suitable for consumers with various needs and meeting the needs of modern users for high-quality input devices. By introducing the arrangement of multiple LED lights 3 in the mechanical axis and magnetic axis design, especially in the magnetic axis keyboard, 2 to 4 LED lights 3 are arranged at the four corners, so that the lighting effect performance of the keyboard is no longer limited to the light projection of a single LED, but can achieve richer lighting changes, gradient effects and dynamic responses. This layout breaks through the limitation of the existing technology that can only support a single LED, and significantly enhances the expressiveness and dynamic sense of the light.

[0140] The lighting effect control method specifically includes the following steps:

[0141] See also Figure 11 The mobile terminal and the RGB lighting control chip establish a data connection relationship through the Bluetooth module. Specifically, the mobile terminal can be a smart phone. Based on the Bluetooth connection between the smart phone and the RGB lighting control chip, remote lighting control can be achieved by controlling the mobile phone APP.

[0142] In addition to the data connection relationship with the mobile terminal, the RGB lighting control chip and the keyboard main chip establish a data connection relationship through the SPI communication protocol. At the same time, the keyboard main chip and the computer driver software establish a three-mode data connection relationship through Bluetooth, data cable or 2.4GHz wireless transmission, which can realize two-way control of the RGB lighting control chip through the computer or mobile terminal.

[0143] The smartphone APP can connect to the RGB lighting control chips of multiple luminous keyboards at the same time, realizing the control of the common lighting effects of multiple luminous keyboards, or performing targeted independent control of different luminous keyboards, thereby presenting different keyboard lighting effects.

[0144] Through the lighting effect control method of the luminous keyboard in the present invention, remote lighting control and synchronous display can be achieved between the mobile phone end and the keyboard end, ensuring real-time updating of the lighting effect.

[0145] The RGB lighting control chip and the keyboard main chip establish a data connection relationship through the SPI communication protocol, realizing the synchronization of the working status of the keyboard RGB lighting control chip and the keyboard main chip, ensuring real-time update of the lighting effects.

[0146] SPI communication and tri-mode data connection enable two-way synchronization between the computer and mobile phone, ensuring the stability and reliability of lighting control. This allows users to freely adjust the lighting effects of the keyboard or pickup light through the mobile app without affecting the keyboard's connection status.

[0147] The smartphone app provides a lighting effect adjustment interface, allowing users to adjust lighting brightness, color, and other parameters. It also communicates with the keyboard's main chip, receiving and sending lighting control commands.

[0148] The RGB lighting control chip synchronizes its connection status with the mobile app via Bluetooth communication and supports SPI communication with the keyboard's main chip to receive lighting control commands. This enables real-time updates of lighting effects, ensuring that the lighting seen by the user is consistent with the application settings.

[0149] The keyboard main chip receives control instructions from the mobile phone application and the RGB lighting control chip to achieve communication with the keyboard hardware, such as controlling touch feedback, etc., to ensure the normal operation of the device functions.

[0150] The PC driver acts as a bridge between the keyboard's main chip and the mobile app, providing the necessary driver functionality. It supports synchronization with the mobile app's lighting effects, ensuring the display of shared lighting effects.

[0151] During use, the user opens the mobile app, selects the RGB lighting control chip to be connected, turns on the Bluetooth connection function, and completes the connection with the RGB lighting control chip. The user can adjust the lighting effect parameters such as brightness, color, mode, etc. through the mobile app.

[0152] The mobile phone application sends lighting control instructions, which are transmitted to the keyboard main chip through SPI communication. The RGB lighting control chip adjusts the lighting effect according to the instructions and synchronizes the status with the mobile phone application through Bluetooth communication.

[0153] The mobile app can connect to multiple RGB lighting control chips of illuminated keyboards simultaneously to achieve shared lighting effects. Users can freely select different lighting modes, such as gradient, flashing, and fading, and apply them to multiple illuminated keyboard devices at the same time.

[0154] Users can adjust the keyboard's lighting effects according to their personal preferences, and support simultaneous control of the lights of multiple keyboards. The mobile phone application and lighting control method connected to the keyboard RGB lighting control chip via Bluetooth have significant advantages in flexibility, scalability, personalization and user experience, and can meet users' needs for diverse lighting effects.

[0155] The keyboard main chip in the present invention is preferably the commonly used 3123 keyboard main IC chip, and the RGB lighting control chip is preferably the 9415 lighting effect slave IC chip to ensure effective control of the above-mentioned lighting effects.

[0156] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.
