Description

Technical Field

[0001] This application relates to the field of keyboard technology, and in particular to a keyboard, electronic device, and electronic device component. Background Technology

[0002] Currently, to enhance the functionality and aesthetics of keyboard keycaps, some keys integrate display functions, capable of displaying preset characters and enabling interactive functionality. In related technologies, the keyboard comprises multiple keys, a base plate, and a membrane circuit. Each key includes a keycap, scissor-switch leads, and a silicone dome. To achieve interactive functionality, a display element is mounted on the surface of the keycap. This display element is electrically connected to the membrane circuit via a flexible circuit board and is used to display preset characters. However, the high cost of the display element contributes to the high cost of the keyboard. Summary of the Invention

[0003] This application provides a keyboard, an electronic device, and an electronic device component that can realize display interaction functions while reducing keyboard costs.

[0004] This application provides a keyboard, including keys and a first light source. Each key includes a keycap and a surface member. The surface member and the first light source are located on opposite sides of the keycap. The surface member is connected to the surface of the keycap and includes color-changing character portions and base character portions. Along the thickness direction of the keyboard, the projections of the base character portions and the color-changing character portions do not overlap. The color-changing character portions are used to switch between a first color and a second color. The first light source emits invisible light toward the surface member. At least a portion of the keycap is a light-transmitting area, which transmits the invisible light to the surface member. Under the illumination of the invisible light, the color-changing character portions change from the first color to the second color.

[0005] During keyboard use, the base character area remains unchanged in color under invisible light, and the user can always see it, enabling the display of basic characters. For example, if the base character area is a white letter "K", the user can see the white "K" regardless of whether invisible light shines on it, guiding the user to press the key corresponding to "K" to input the letter. Invisible light emitted from the first light source passes through the light-transmitting area of ​​the keycap and illuminates the color-changing character area, causing the color-changing character area, made of color-changing ink, to change from a first color to a second color, thus displaying the corresponding character. For example, if the color-changing character area represents an email address, the email address can change from transparent to red under invisible light, allowing the user to see the red email address and enabling interaction.

[0006] The color-changing characters are made with color-changing ink, which has photosensitive properties and changes color when exposed to invisible light. Therefore, utilizing the photosensitive properties of color-changing ink to achieve display functionality eliminates the need for display components in existing technologies. Furthermore, the low cost of the primary light source and the color-changing ink allows for low-cost display. Additionally, this display method does not occupy internal keyboard space, reducing layout complexity. Moreover, it eliminates the need for additional flexible circuit boards, reducing the risks associated with microswitches and improving reliability. Finally, by incorporating a base character section, the basic keyboard input function is guaranteed, meeting user needs.

[0007] In one possible implementation, the surface element includes multiple character layers stacked along the thickness direction of the keyboard, each character layer including a color-changing character portion. A first light source emits multiple invisible light wavelengths, each character layer corresponding to one wavelength of invisible light, and the color-changing character portion in each character layer changes from a first color to a second color under illumination by the corresponding wavelength of invisible light.

[0008] In this way, by controlling the first light source to emit invisible light of different wavelengths, the color-changing characters at different positions can change from the first color to the second color, thus realizing the display of multiple characters, increasing the display range of the buttons, and further improving the display effect.

[0009] In one possible implementation, the projections of the color-changing character portions in two adjacent character layers overlap along the thickness direction of the keyboard.

[0010] In this way, at the same time, the first light source emits an invisible light of a certain wavelength, causing the color-changing character part in one character layer to change from the first color to the second color. This means that the color-changing character parts in any two character layers do not need to avoid each other in the thickness direction of the keyboard, which can increase the display area of ​​the color-changing character parts.

[0011] In one possible implementation, the first color of any two color-changing character sections is the same. The second color of the color-changing character sections in at least two character layers is different, or the second color of the color-changing character sections in any two character layers is the same.

[0012] This avoids displaying multiple colors on the surface when the primary light source does not emit invisible light, thus improving the button's aesthetics. Furthermore, when the second colors of the color-changing characters in the two character layers are different, the distinction between the different color-changing characters can be further enhanced.

[0013] In one possible implementation, at least one character layer includes a plurality of color-changing character sections, wherein at least two color-changing character sections in the same character layer have different second colors.

[0014] This improves the distinguishability of multiple color-changing characters displayed within the same character layer, thus enhancing the display effect.

[0015] In one possible implementation, along the thickness direction of the keyboard, the character layer closest to the keycaps includes the base character portion.

[0016] In this way, the base character section can be protected by other character layers, which helps to extend the service life of the base character section.

[0017] In one possible implementation, each character layer further includes a protective section, the color of which is the same as the first color of the color-changing character section.

[0018] This prevents wear on the color-changing characters, thus extending their lifespan. Furthermore, since the initial color of the color-changing characters matches the color of the protective layer, the button's appearance is enhanced when the primary light source is not emitting invisible light.

[0019] In one possible implementation, the projection of the color-changing characters overlaps with the projection of the first light source along the thickness direction of the keyboard.

[0020] In this way, the invisible light emitted by the first light source can easily illuminate the color-changing character part, which can reduce the difficulty of coupling between the color-changing character part and the invisible light.

[0021] In one possible implementation, the keyboard further includes a second light source located on the same side of the keycaps along the thickness direction of the keyboard. The second light source is used to emit visible light. The light-transmitting area is also used to transmit visible light to the surface components, where the base characters emit light under visible light illumination, and the color-changing characters emit light under visible light illumination when they are in a second color.

[0022] In this way, during the use of the keyboard, the base character area and / or color-changing character area are illuminated by visible light, causing the base character area and color-changing character area to emit light, which can further improve the display effect.

[0023] In one possible implementation, the projection of the base character portion overlaps with the projection of the second light source along the thickness direction of the keyboard.

[0024] This reduces the difficulty of coupling the substrate character part with visible light, making it easier for visible light to reach the substrate character part.

[0025] In one possible implementation, the keycap includes an opaque area and a translucent area, the translucent area being used to transmit visible and invisible light to the surface component, and along the thickness direction of the keyboard, a portion of the projection of the translucent area overlaps with the projection of the color-changing character portion, and another portion overlaps with the projection of the base character portion.

[0026] This combination of opaque and translucent areas can block unnecessary light transmission paths, thus improving the display effect.

[0027] In one possible implementation, the keyboard further includes a circuit board, with the surface member and the circuit board located on opposite sides of the keycaps along the thickness direction of the keyboard, and the circuit board including at least one of a first light source and a second light source.

[0028] In this way, integrating the first light source and / or the second light source onto the circuit board can improve the keyboard's integration level. Additionally, the circuit board can be used to receive control signals and control the first and / or second light sources to emit light.

[0029] In one possible implementation, the key further includes at least one of a light-transmitting scissor-switch mechanism and a light-transmitting elastic element, wherein the light-transmitting scissor-switch mechanism and the light-transmitting elastic element are located on the same side of the keycap as the first light source.

[0030] In this way, visible light can pass through the light-transmitting scissor feet and the light-transmitting elastic element, and shine on the base character section and the color-changing character section, causing the base character section and the color-changing character section to emit light, which helps to improve the display effect.

[0031] A second aspect of this application provides an electronic device including a housing and a keyboard as described in any of the first aspects, the keyboard being mounted on the housing.

[0032] A third aspect of this application provides an electronic device component, including an electronic device and a keyboard as described in any of the first aspects, the keyboard being used for communicative connection with the electronic device. Attached Figure Description

[0064] X, thickness direction. Detailed Implementation

[0065] The keyboard is the most commonly used and primary input device. A keyboard includes at least one key. When a user presses one of these keys, the keyboard outputs specific signals to electronic devices (such as desktop computers, tablets, etc.), such as characters, power commands, and directional control commands. Therefore, the keyboard allows users to input English letters, Chinese characters, numbers, punctuation marks, control commands, etc., into electronic devices, enabling operations such as issuing commands and inputting data. To enhance the functionality and aesthetics of the keyboard keycaps, some keys integrate display functions, showing preset characters and enabling interactive features.

[0066] Figure 1 This is a cross-sectional schematic diagram of a keyboard in the related art.

[0067] In one embodiment, the keyboard 210 includes keys 218, a circuit board 213, and a metal substrate 214. The keys 218 include keycaps 211, electrical connectors 215, elastic members 216, and display elements 212. The keycaps 211, elastic members 216, and display elements 212 are all disposed on one side of the metal substrate 214, and the circuit board 213 is disposed on the other side of the metal substrate 214. The elastic member 216 is disposed between the metal substrate 214 and the keycaps 211. The elastic member 216 is used to give the keycaps 211 a tendency to move away from the metal substrate 214, so that after the pressure applied to the keycaps 211 is removed, the elastic member 216 drives the keycaps 211 to move away from the metal substrate 214, causing the keycaps 211 to return from the pressed position to the initial position. The display element 212 is connected to the surface of the keycaps 211 and is used to display preset characters. The electrical connector 215 electrically connects the circuit board 213 and the display element 212. The electrical connector 215 is a flexible cable (e.g., a flexible cable). Figure 1(As shown) or a flexible circuit board, the circuit board 213 is used to transmit current or control signals to the display element 212 through the electrical connector 215 to ensure the normal operation of the display element 212. The electrical connector 215 is provided with redundant length to prevent the electrical connector 215 from being pulled by the keycap 211 during the movement of the keycap 211, and to prevent the connection at both ends of the electrical connector 215 from breaking.

[0068] However, the redundant electrical connector 215 occupies a significant amount of internal space within the keyboard 210. This can cause the redundant connector 215 to easily jam into moving parts within the keyboard 210 during key presses, hindering key presses and affecting the tactile feedback. Furthermore, the connector 215 is prone to micro-movements, leading to poor contact between it and the circuit board 213 and / or the display element 212, resulting in abnormal display functionality. In addition, the cost of the display element 212 and the complexity of the keyboard 210 assembly process contribute to the high cost of the keyboard 210.

[0069] In another embodiment, the electrical connector 215 is replaced with a conductive silicone cap, which has conductive and non-conductive portions to achieve electrical connection between the display element and the circuit board. However, this method reduces the lifespan of the button. Furthermore, the conductive resistance of the conductive silicone cap decreases with prolonged pressing. In addition, the pre-pressure of the conductive silicone cap is prone to instability, leading to poor contact continuity.

[0070] Figure 2 This is a cross-sectional view of another type of keyboard in the related technology.

[0071] In another embodiment, the keyboard 220 includes an e-ink display screen 221, transparent keycaps 222, a rubber dome plate 223, and a key frame 224. The transparent keycaps 222, the rubber dome plate 223, and the key frame 224 are all disposed on the display side of the e-ink display screen 221. A portion of the rubber dome plate 223 is located between the key frame 224 and the e-ink display screen 221, and another portion is disposed within the key holes 225 of the key frame 224 and connected to the transparent keycaps 222. Along the thickness direction of the keyboard 220 (e.g., along the thickness direction of the keyboard 220...), Figure 2 In the X direction, the area opposite the ink display 221 and the transparent keycap 222 can display corresponding characters, and the user can see the characters displayed on the ink display 221 through the transparent keycap 222.

[0072] However, the characters displayed on the e-ink display 221 have a noticeable depth-of-field problem, which can lead to visual distortion. Furthermore, the high cost of the e-ink display 221 results in a high cost for the keyboard 220. In addition, the excessive number of keys with transparent keycaps 222 makes it impractical for many applications.

[0073] In view of this, embodiments of this application provide a keyboard 100, an electronic device 200, and an electronic device assembly 500. By utilizing the photosensitive properties of color-changing ink and combining it with invisible light to change the color of the ink, low-cost character display is achieved, reducing the cost of the keyboard 100. Furthermore, it does not occupy internal space of the keyboard 100. In addition, electrical connectors can be eliminated, reducing the risks associated with microswitches and improving reliability.

[0074] The keyboard 100 provided in this application embodiment can be applied to foldable electronic devices 200, such as foldable mobile phones, laptops, etc. Alternatively, it can also be applied to wearable electronic products, tablet computers, desktop computers, smart home terminals, and other electronic devices 200. This application embodiment does not impose specific limitations.

[0075] Figure 3 This is a three-dimensional structural diagram of an electronic device provided in an embodiment of this application.

[0076] See Figure 3 As shown, the electronic device 200 provided in this application embodiment includes a keyboard 100 and a housing 201. The keyboard 100 is installed on the housing 201. English letters, Chinese characters, numbers, punctuation marks, control commands, etc. can be input into the electronic device 200 through the keyboard 100.

[0077] The electronic device 200 can be a foldable phone, laptop computer, wearable electronic product, tablet computer, game controller, calculator, or PDA (personal digital assistant). In this embodiment, a laptop computer is used as an example for illustration. Figure 3 As shown.

[0078] See Figure 3 As shown, in addition to the keyboard 100, the laptop computer may also include a display screen 300, which is signal-connected to the keyboard 100 and can be used to display the input operations of the keyboard 100.

[0079] Figure 4 This is a schematic diagram of the structure of an electronic device component provided in an embodiment of this application.

[0080] See Figure 4 As shown in the figure, an electronic device component 500 provided in this application embodiment includes an electronic device 200 and a keyboard 100. The keyboard 100 is communicatively connected to the electronic device 200, and English letters, Chinese characters, numbers, punctuation marks, control commands, etc. can be input into the electronic device 200 through the keyboard 100.

[0081] Among them, electronic device 200 can be a desktop computer, tablet computer, or display device, such as... Figure 4 As shown, the electronic device 200 in the electronic device component 500 is illustrated by taking a desktop computer as an example. The electronic device 200 includes a display screen 300, a host computer 400, etc. The host computer 400 is communicatively connected to the display screen 300.

[0082] The keyboard 100 provided in this application can be used as an accessory for a desktop computer. The keyboard 100 can be connected to a desktop computer (e.g., the host computer 400 of the desktop computer) via a communication interface to control the desktop computer by pressing the keyboard 100.

[0083] In the embodiments of this application, "communication connection" can refer to electrical signal transmission, including wireless communication connections and wired communication connections. Wireless communication connections do not require a physical medium and are not considered connections that limit the structure of a product.

[0084] In some implementations, the keyboard 100 can wirelessly connect to the electronic device 200 via wireless communication methods such as Bluetooth. In other implementations, the keyboard 100 can also wiredly connect to the signal electronic device 200 via wired connections such as wires or data cables.

[0085] The implementation of the keyboard 100 provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0086] Figure 5 This is a schematic diagram of a keyboard structure provided in an embodiment of this application. Figure 6 for Figure 5 The diagram shows a cross-sectional view of a single key in conjunction with the circuit board and base plate when the keyboard casing is removed.

[0087] See Figure 5 and Figure 6 As shown, the keyboard 100 provided in this embodiment includes keys 10, a first light source 20, a housing 50, and a base plate 60. The first light source 20 and the base plate 60 are both disposed inside the housing 50. A portion of the keys 10 is disposed inside the housing 50, and another portion is disposed outside the housing 50. Figure 6 As shown, along the thickness direction X of the keyboard 100, the first light source 20 and the key 10 are disposed on the same side of the base plate 60. The projection of the key 10 on the thickness direction X of the keyboard 100 covers the projection of the first light source 20 on the thickness direction X of the keyboard 100. The base plate 60 is used to support the key 10 and the first light source 20, and to fix the keyboard 100.

[0088] The number of buttons 10 can be one or more. In some implementations, such as... Figure 5As shown, the number of buttons 10 can be multiple. In some other implementations, the keyboard 100 may also have only a single button 10 (not shown in the figure). For example, when the keyboard 100 is only used for switching, the keyboard 100 may have only one switch button 10.

[0089] The key 10 has a pressed position and a non-pressed position, and the key 10 can reciprocate between the pressed position and the non-pressed position; in other words, the key 10 can move up and down between the pressed position and the non-pressed position. When the key 10 is in the pressed position, the keyboard 100 outputs a signal matching the pressed key 10. In some implementations, when there are multiple keys 10, each of the multiple keys 10 can reciprocate between the pressed position and the non-pressed position.

[0090] The number of first light sources 20 can be one or more. In some implementations, there can be multiple first light sources 20, with each first light source 20 corresponding to one key 10, and the projection of each first light source 20 onto the thickness direction X of the keyboard 100 is covered by the projection of the corresponding key 10 onto the thickness direction X of the keyboard 100. In other implementations, the number of first light sources 20 can be one, in which case each first light source 20 corresponds to one key 10.

[0091] The button 10 corresponding to the first light source 20 can be a button with a large aspect ratio (i.e., a long button) or a function button, such as the shift key, space bar, enter key, and the "0" and "+" keys 10 on the numeric keypad 100. It can also be a regular button with a small aspect ratio, such as the number keys 1 to 9, the 26 letter keys 10, etc. It can also be a special button with a special shape, such as an enter key set to an "L" shape.

[0092] In some implementations, the multiple buttons 10 corresponding to the first light source 20 may simultaneously include multi-dimensional buttons with a large aspect ratio (i.e., long buttons), special buttons, and ordinary buttons with a small aspect ratio. In other implementations, the multiple buttons 10 corresponding to the first light source 20 may only include ordinary buttons, multi-dimensional buttons, or special buttons.

[0093] like Figure 6As shown, the key 10 includes a keycap 12 and a surface member 11. The surface member 11 is connected to the surface of the keycap 12. Along the thickness direction X of the keyboard 100, the surface member 11 and the first light source 20 are located on opposite sides of the keycap 12, with the keycap 12 positioned between the surface member 11 and the base plate 60. The surface member 11 includes a color-changing character portion 112 and a base character portion 113. Along the thickness direction X of the keyboard 100, the projection of the base character portion 113 does not overlap with the projection of the color-changing character portion 112. The color-changing character portion 112 is used to switch between a first color and a second color. The first light source 20 emits invisible light towards the surface member 11. At least a portion of the keycap 12 is a light-transmitting area 121, which transmits invisible light to the surface member 11. Under the illumination of invisible light, the color-changing character portion 112 changes from the first color to the second color, while the color of the base character portion 113 remains unchanged under the illumination of invisible light.

[0094] During the use of the keyboard 100, the base character section 113 does not change color under invisible light, and the user can always see the base character section 113, thus displaying the basic characters. For example, when the base character section 113 is a white letter "K", the user can see the white character "K" regardless of whether invisible light shines on it, guiding the user to press the key 10 corresponding to "K" to input "K". The invisible light emitted by the first light source 20 passes through the light-transmitting area 121 of the keycap 12 and shines on the color-changing character section 112, causing the color-changing character section 112, made of color-changing ink, to change from the first color to the second color, thus displaying the corresponding character. For example, when the color-changing character section 112 is an email character, the email character can change from transparent to red under invisible light, allowing the user to see the red email character and achieve interaction.

[0095] The color-changing character section 112 is made of color-changing ink, which has photosensitive properties and changes color under invisible light. Therefore, by utilizing the photosensitive properties of color-changing ink to achieve the display function, the display element in existing technologies can be eliminated. Furthermore, the first light source 20 and the color-changing ink are low-cost, enabling low-cost display. In addition, this display method does not occupy internal space in the keyboard 100, reducing layout complexity. Moreover, there is no need to add an additional flexible circuit board, reducing the risk associated with micro-motion and improving reliability.

[0096] The base character section 113 does not change color when exposed to invisible light. The base character section 113 can display basic characters, such as the numbers 1 to 9, the 26 letters, the shift character, etc., to realize the basic functions of the key 10 and meet the user's needs.

[0097] In this embodiment, the base character portion 113 is a non-transparent color. For example, the base character portion 113 can be white. Of course, the base character portion 113 can also be other colors, such as yellow, blue, etc.

[0098] The specific shape of the color-changing character section 112 is not limited here. The color-changing character section 112 can be a mail identifier (e.g., Figure 9 As shown), smiley face icon (e.g.) Figure 10 As shown), mobile phone logo (e.g.) Figure 11 (as shown) and other signs.

[0099] For example, the first color can be transparent. Of course, the first color can also be other colors, such as yellow, red, etc.

[0100] For example, the second color can be orange. Of course, the second color can also be other colors, such as blue.

[0101] It should be noted that when there are multiple buttons 10 with surface parts 11, the first color of the color-changing character parts 112 in the multiple buttons 10 may be at least partially the same or different, and the second color of the color-changing character parts 112 in the multiple buttons 10 may be at least partially the same or different.

[0102] In some possible implementations, the surface member 11 may include multiple character layers 111, which are stacked along the thickness direction X of the keyboard 100. Each character layer 111 includes a color-changing character portion 112, and one of the character layers 111 includes a base character portion 113. The first light source 20 is used to emit a variety of invisible light of different wavelengths, and each character layer 111 corresponds to one wavelength of invisible light. The color-changing character portion 112 in each character layer 111 changes from a first color to a second color under the illumination of the corresponding wavelength of invisible light.

[0103] In this way, by controlling the first light source 20 to emit invisible light of different wavelengths, the color-changing character section 112 at different positions changes from the first color to the second color, realizing the display of multiple characters, which can increase the display range of the button 10 and further improve the display effect.

[0104] It should be noted that, in addition to being composed of multiple character layers 111, in some embodiments, the surface member 11 may also include a protective portion 114, a base character portion 113, and a color-changing character portion 112, with the protective portion 114 protecting the base character portion 113 and the color-changing character portion 112. That is to say, the surface member 11 is structurally equivalent to a single-layer character layer 111.

[0105] For example, such as Figure 6 As shown, the surface component 11 may include two character layers 111, which are stacked along the thickness direction X of the keyboard 100. The two character layers 111 include a first character layer 111A and a second character layer 111B. Along the thickness direction X of the keyboard 100, the first character layer 111A is located between the second character layer 111B and the keycap 12, and is fixedly connected to both the second character layer 111B and the keycap 12. The first character layer 111A includes a first color-changing character portion 112A, and the second character layer 111B includes a second color-changing character portion 112B. The first light source 20 can emit two invisible lights of different wavelengths, corresponding to the first color-changing character portion 112A and the second color-changing character portion 112B, causing the colors of the first color-changing character portion 112A and the second color-changing character portion 112B to change.

[0106] Figure 7 for Figure 6 A cross-sectional schematic diagram of the first light source emitting invisible light of the first wavelength. Figure 8 for Figure 6 A cross-sectional schematic diagram of the first light source emitting invisible light of the second wavelength. Figure 9 for Figure 6 The diagram shown illustrates one scenario for the button. Figure 10 for Figure 6 The diagram shows another scenario for the button.

[0107] Specifically, since the first color is transparent, when the first light source 20 does not emit invisible light, such as Figure 9 As shown in Figure a, the user cannot see the character represented by the color-changing character section 112; at this time, the user can see the character represented by the base character section 113. For example, Figure 9 As shown, the base character section 113 includes the digits "1" and "!", but the base character section 113 can also be other characters.

[0108] like Figure 7 As shown, the first light source 20 emits invisible light of a first wavelength (e.g., Figure 7 When (as shown in Figure A), invisible light of the first wavelength passes through the first color-changing character section 112A and the second color-changing character section 112B, the photosensitivity of the first color-changing character section 112A matches the photosensitivity of the first wavelength of invisible light, while the photosensitivity of the second color-changing character section 112B does not match the photosensitivity of the first wavelength of invisible light. Therefore, the first color-changing character section 112A changes from the first color to the second color, while the color of the second color-changing character section 112B remains unchanged; it remains the first color. Thus, the first color-changing character section 112A can be displayed, and the user can see it, but will not see the second color-changing character section 112B. For example... Figure 9As shown in Figure b, the user can see the email icon represented by the first color-changing character section 112A, and the color of the email icon is no longer transparent.

[0109] When the first light source 20 emits invisible light of the second wavelength (such as...) Figure 8 When (as shown in Figure B), the second wavelength of invisible light passes through the first color-changing character section 112A and the second color-changing character section 112B. Because the photosensitive characteristics of the second color-changing character section 112B match the second wavelength of invisible light, while the photosensitive characteristics of the first color-changing character section 112A do not match the second wavelength of invisible light, the second color-changing character section 112B changes from the first color to the second color, while the color of the first color-changing character section 112A remains unchanged; it remains the first color. Therefore, the second color-changing character section 112B can be displayed, and the user can see the second color-changing character section 112B but will not see the first color-changing character section 112A. For example... Figure 9 As shown in Figure c, the user can see the information mark represented by the second color-changing character section 112B, and the color of the information mark is no longer transparent.

[0110] Therefore, at the same time, the first light source 20 emits invisible light of a certain wavelength, causing a color-changing character part 112 in the surface part 11 to change color and be seen by the user.

[0111] It should be noted that, in addition to emitting invisible light of the first wavelength first, the first light source 20 can also emit invisible light of the second wavelength first. That is to say, the second color-changing character section 112B can change color first, and then the first color-changing character section 112A can change color.

[0112] like Figure 9 As shown, the first color-changing character section 112A and the second color-changing character section 112B have different shapes. However, in some implementations, the shapes of the first color-changing character section 112A and the second color-changing character section 112B can be the same. In this case, the second colors of the shapes of the first color-changing character section 112A and the second color-changing character section 112B are different, and the shapes of the first color-changing character section 112A and the second color-changing character section 112B can be distinguished by color to realize interactive scenarios, for example... Figure 10 As shown, both the first color-changing character section 112A and the second color-changing character section 112B are smiley face shapes. The second color of the first color-changing character section 112A can be yellow, and the second color of the second color-changing character section 112B can be green. However, the second colors of the first color-changing character section 112A and the second color-changing character section 112B can also be other colors.

[0113] Figure 11 for Figure 6 This is another scenario illustration of the button shown.

[0114] In some other implementations, the shapes of the first color-changing character portion 112A and the second color-changing character portion 112B may also be partially the same, for example... Figure 11 As shown, both the first color-changing character section 112A and the second color-changing character section 112B include a mobile phone icon; however, the second color-changing character section 112B also includes a signal icon. When the first color-changing character section 112A is displayed, it indicates that there is a terminal device near the keyboard 100 that can be communicated with; the terminal device can be a tablet computer, a mobile phone, or other similar device. When the second color-changing character section 112B is displayed, it indicates that the keyboard 100 and the terminal device have established a communication connection. Therefore, device interconnection scenarios can also be achieved using color-changing character sections 112 of different shapes.

[0115] It should be noted that, in addition to using two color-changing character units 112 to achieve the above-mentioned scenarios, more than two color-changing character units 112 can also be used. Furthermore, multiple color-changing character units 112 can achieve other scenarios besides those mentioned above, which will not be elaborated upon here.

[0116] In some possible implementations, along the thickness direction X of the keyboard 100, the projections of the color-changing character portions 112 in two adjacent character layers 111 onto the thickness direction X of the keyboard 100 can overlap, for example, as shown in... Figure 6 As shown, along the thickness direction X of the keyboard 100, the projection of the first color-changing character portion 112A in the first character layer 111A overlaps with the projection of the second color-changing character portion 112B in the second character layer 111B.

[0117] By overlapping the projections of the color-changing character portions 112 in adjacent character layers 111 along the thickness direction X of the keyboard 100, the area of ​​the color-changing character portions 112 in each character layer 111 can be increased, thereby improving the display area and display effect. Furthermore, since the first light source 20 emits invisible light of a single wavelength at the same time, one of the overlapping color-changing character portions 112 changes color while the others remain unchanged. Combined with the fact that the first color is transparent, this does not affect the display of the color-changing character portions 112 near the keycaps 12.

[0118] In some possible implementations, the first color of any two color-changing character parts 112 can be the same, for example, such as Figure 6As shown, the first color-changing character part 112A and the second color-changing character part 112B have the same first color. The first color of the first color-changing character part 112A and the second color-changing character part 112B is transparent. When the first light source 20 does not emit invisible light that matches the first color-changing character part 112A or the second color-changing character part 112B, the first color-changing character part 112A and the second color-changing character part 112B cannot be seen by the user. This can prevent the surface part 11 from displaying multiple colors and improve the aesthetics of the button 10.

[0119] In some possible implementations, the second color of the color-changing character portions 112 in at least two character layers 111 is different, for example... Figure 6 As shown, there are two character layers 111. The second color of the first color-changing character section 112A can be green, and the second color of the second color-changing character section 112B can be orange. When the first light source 20 emits invisible light that matches the first color-changing character section 112A or the second color-changing character section 112B, the green first color-changing character section 112A or the orange second color-changing character section 112B can be displayed, which can improve the distinction of the color-changing character sections 112 in different character layers 111 and improve the display effect.

[0120] When the number of character layers 111 exceeds two, the second color of some of the color-changing character parts 112 in all character layers 111 can be the same, and the second color of other parts of the color-changing character parts 112 can be different.

[0121] It should be noted that, apart from being different, in some embodiments, the second color of the color-changing character portions 112 in any two character layers 111 can also be the same.

[0122] For example, each character layer 111 may include a color-changing character section 112, such as Figure 6 As shown, there are two character layers 111, and each character layer 111 includes a color-changing character section 112. However, in some possible implementations, at least one character layer 111 may also include multiple color-changing character sections 112.

[0123] When the character layer 111 includes multiple color-changing character sections 112, the second colors of at least two color-changing character sections 112 in the same character layer 111 can be different, or the second colors of all color-changing character sections 112 in the same character layer 111 can be the same. When the second colors of at least two color-changing character sections 112 in the same character layer 111 are different, the distinguishability of multiple color-changing character sections 112 in the same character layer 111 can be improved, which helps to improve the display effect.

[0124] In some possible implementations, along the thickness direction X of the keyboard 100, the projection of the color-changing character portion 112 can overlap with the projection of the first light source 20, for example... Figure 6 As shown, along the thickness direction X of the keyboard 100, the projection of the first color-changing character portion 112A overlaps with the projection of the first light source 20, and the projection of the second color-changing character portion 112B overlaps with the projection of the first light source 20. In this way, the invisible light emitted by the first light source 20 can easily illuminate the color-changing character portion 112, which can reduce the difficulty of coupling between the color-changing character portion 112 and the invisible light.

[0125] It should be noted that, in addition to overlapping with the projection of the first light source 20 on the thickness direction X of the keyboard 100, the projection of the color-changing character part 112 on the thickness direction X of the keyboard 100 may also not overlap with the projection of the first light source 20 on the thickness direction X of the keyboard 100.

[0126] In some possible implementations, the first light source 20 can be an invisible LED light source. Of course, the first light source 20 can also be other light sources that emit invisible light.

[0127] For example, such as Figure 6 As shown, each character layer 111 also includes a protective portion 114, the color of which is the same as the first color of the color-changing character portion 112. This prevents wear on the color-changing character portion 112 and helps extend its lifespan. Furthermore, the fact that the first color of the color-changing character portion 112 is the same as the color of the protective portion 114 enhances the aesthetics of the button 10 when the first light source 20 is not emitting invisible light.

[0128] The first color is transparent, therefore the protective part 114 is also transparent. This ensures that most of the surface part 11 has a uniform color when the first light source 20 is not emitting light, improving aesthetics. Furthermore, it allows the user to see the base character part 113.

[0129] The protective portion 114 is made of a light-transmitting material. When visible light illuminates the base character portion 113 and the second-color-changing character portion 112, the base character portion 113 and the second-color-changing character portion 112 can be seen to emit light. The specific material of the protective portion 114 is not limited here. For example, the protective portion 114 can be UV-sensitive.

[0130] For example, the material of the protective portion 114 in any two character layers 111 can be the same, so that the color of the protective portion 114 in any two character layers 111 can be the same, for example... Figure 6 As shown, the material of the protective part 114 in any two character layers 111 is UV.

[0131] The relative positional relationship between the protective portion 114 and the color-changing character portion 112 is not limited here. In some implementations, the protective portion 114 has a first groove for accommodating the color-changing character portion 112 on the side facing the keycap 12 along the thickness direction X of the keyboard 100. In other implementations, the protective portion 114 has a first through hole for accommodating the color-changing character portion 112 along the thickness direction X of the keyboard 100.

[0132] The relative positional relationship between the protective portion 114 and the base character portion 113 is not limited here. In some implementations, the protective portion 114 has a second groove for accommodating the base character portion 113 on the side facing the keycap 12 along the thickness direction X of the keyboard 100. In other implementations, the protective portion 114 has a second through hole for accommodating the base character portion 113 along the thickness direction X of the keyboard 100.

[0133] In some possible implementations, along the thickness direction X of the keyboard 100, the character layer 111 closest to the keycap 12 includes a base character portion 113, for example... Figure 6 As shown, there are two character layers 111. The character layer 111 closest to the keycap 12 is the first character layer 111A, which includes the base character portion 113. In this way, the base character portion 113 can be protected by the other character layers 111, which helps to improve the service life of the base character portion 113.

[0134] It should be noted that the base character portion 113 may be included in other character layers 111 besides the character layer 111 closest to the keycap 12. For example, the character layer 111 furthest from the keycap 12 along the thickness direction X of the keyboard 100 may also include the base character portion 113.

[0135] Figure 12 for Figure 6 A schematic diagram showing the second light source emitting visible light in the button shown.

[0136] In some possible implementations, such as Figure 12 As shown, the keyboard 100 may further include a second light source 30. Along the thickness direction X of the keyboard 100, the second light source 30 and the first light source 20 are located on the same side of the keycap 12. The second light source 30 is used to emit visible light (such as...). Figure 12(As shown in C1 and C2). The light-transmitting area 121 is also used to transmit visible light to the surface member 11. The base character portion 113 emits light under the illumination of visible light, and the color-changing character portion 112 emits light under the illumination of visible light when it is in the second color. In this way, during the use of the keyboard 100, the base character portion 113 and / or the color-changing character portion 112 are illuminated by visible light, causing the base character portion 113 and the color-changing character portion 112 to emit light, which can further improve the display effect.

[0137] When the first light source 20 does not emit light and the second light source 30 emits visible light, such as Figure 12 As shown, visible light will (e.g.) Figure 12 As shown in C1 and C2, light simultaneously illuminates the base character section 113 and the color-changing character section 112, and passes through them. At this time, the base character section 113 emits light, and because the color of the color-changing character section 112 is the first color, the character represented by the color-changing character section 112 will not be displayed. The user can see the base character section 113 emitting light, but will not see the color-changing character section 112. The emitting light of the base character section 113 can also be understood as an increase in the brightness of the area where the base character section 113 is located.

[0138] When the first light source 20 and the second light source 30 emit light simultaneously (e.g.) Figure 7 or Figure 8 As shown, when the base character portion 113 emits light under visible light, the color-changing character portion 112 changes from a first color to a second color under invisible light, and simultaneously emits light under visible light. The emission of light by the color-changing character portion 112 can also be understood as an increase in brightness in the area where the color-changing character portion 112 is located.

[0139] like Figure 12 As shown, the first light source 20 and the second light source 30 are in one-to-one correspondence, and the number of first light sources 20 is the same as the number of second light sources 30. Therefore, it can be concluded that the number of second light sources 30 can be one or more.

[0140] For example, the second light source 30 can be a visible light LED light source. Of course, the second light source 30 can also be other light sources capable of emitting visible light.

[0141] like Figure 12 As shown, along the thickness direction X of the keyboard 100, the projection of the first light source 20 and the projection of the second light source 30 do not overlap, thus avoiding mutual interference between the first light source 20 and the second light source 30, ensuring that visible light illuminates the base character portion 113 and the color-changing character portion 112, and that invisible light illuminates the color-changing character portion 112.

[0142] In some possible implementations, such as Figure 12As shown, along the thickness direction X of the keyboard 100, the projection of the base character portion 113 and the projection of the second light source 30 can overlap, which can reduce the difficulty of coupling the base character portion 113 with visible light, and make it easier for visible light to illuminate the base character portion 113.

[0143] It should be noted that, in some embodiments, the projection of the base character portion 113 on the thickness direction X of the keyboard 100 may not overlap with the projection of the second light source 30 on the thickness direction X of the keyboard 100.

[0144] Figure 13 for Figure 6 The keycaps in the image are shown in a top-down view.

[0145] See also some possible implementations. Figure 6 and Figure 13 As shown, the keycap 12 may include an opaque area 122 and a translucent area 121. The opaque area 122 prevents both visible and invisible light from passing through to the surface member 11; that is, visible and invisible light cannot pass through the opaque area 122. The translucent area 121 transmits both visible and invisible light to the surface member 11. Along the thickness direction X of the keyboard 100, a portion of the projection of the translucent area 121 overlaps with the projection of the color-changing character portion 112, and another portion overlaps with the projection of the base character portion 113. This hybrid design of the opaque area 122 and the translucent area 121 blocks unnecessary light transmission paths, contributing to improved display quality.

[0146] like Figure 6 and Figure 13 As shown, the light-transmitting area 121 may include a first area 1211 and a second area 1212, which are separated by an opaque area 122. Along the thickness direction X of the keyboard 100, the projection of the first area 1211 overlaps with the projection of the color-changing character portion 112, and the first area 1211 is used to transmit visible and invisible light to the color-changing character portion 112. Along the thickness direction X of the keyboard 100, the projection of the second area 1212 overlaps with the projection of the base character portion 113, and the second area 1212 is used to transmit visible and invisible light to the base character portion 113.

[0147] In some embodiments, such as Figure 6As shown, along the thickness direction X of the keyboard 100, the projection of the first region 1211 may include the projection of the color-changing character part 112. That is, the projection of the first region 1211 covers the color-changing character part 112, which can ensure that all parts of the color-changing character part 112 are irradiated by visible light and / or invisible light, thereby improving the luminous effect of the color-changing character part 112.

[0148] In some embodiments, such as Figure 6 As shown, along the thickness direction X of the keyboard 100, the projection of the second region 1212 may include the projection of the base character portion 113. That is, the projection of the second region 1212 covers the base character portion 113, which can ensure that all parts of the base character portion 113 are illuminated by visible light and improve the light emission effect of the base character portion 113.

[0149] For example, such as Figure 6 As shown, the keyboard 100 also includes a circuit board 40. Along the thickness direction X of the keyboard 100, the surface member 11 and the circuit board 40 are located on opposite sides of the keycap 12. The circuit board 40 may include a contact portion 42, which functions similarly to a switch. When the key 10 presses the contact portion 42, the circuit board 40 can output a signal corresponding to the key 10, thereby realizing the signal input function of the keyboard 100.

[0150] In some possible implementations, the circuit board 40 may include a main board body 41 and at least one of a first light source 20 and a second light source 30, for example... Figure 6 As shown, the circuit board 40 includes a main board body 41, a first light source 20, and a second light source 30. The first light source 20 and the second light source 30 are respectively connected to the same side of the main board body 41 and are electrically connected to the main board body 41. The main board body 41 includes a contact part 42. The main board body 41 is used for control electrical connection with the electronic device 200. On the one hand, the main board body 41 realizes the signal input function of the keyboard 100. On the other hand, the main board body 41 can also control the first light source 20 to emit invisible light of a certain wavelength according to the control signal output by the controller of the electronic device 200, and control the second light source 30 to emit visible light.

[0151] In this way, integrating the first light source 20 and / or the second light source 30 onto the circuit board 40 can improve the integration level of the keyboard 100. Additionally, the circuit board 40 can be used to receive control signals and control the first light source 20 and / or the second light source 30 to emit light.

[0152] like Figure 6As shown, the first light source 20 and the second light source 30 are both integrated on the circuit board 40. However, one of the first light source 20 and the second light source 30 can also be integrated on the circuit board 40. In this case, the circuit board 40 may include the main board body 41 and one of the first light source 20 and the second light source 30. The other of the first light source 20 and the second light source 30 is a separate device from the circuit board 40.

[0153] It should be noted that, in some embodiments, in addition to being integrated on the circuit board 40, the circuit board 40, the first light source 20, and the second light source 30 are three independent devices. That is, the circuit board 40, the first light source 20, and the second light source 30 are in parallel. In this case, the circuit board 40 can be electrically connected to the first light source 20 and the second light source 30 respectively, and the circuit board 40 can control the first light source 20 and / or the second light source 30 to emit light.

[0154] In some possible implementations, such as Figure 6 As shown, the key 10 may also include an elastic element 13, which is disposed between the keycap 12 and the circuit board 40 along the thickness direction X of the keyboard 100. When the keycap 12 is pressed, the keycap 12 moves toward the circuit board 40, and at the same time, the keycap 12 squeezes the elastic element 13, causing the elastic element 13 to undergo elastic deformation until the elastic element 13 squeezes the contact portion 42 of the circuit board 40, so that the circuit corresponding to the contact portion 42 of the circuit board 40 is turned on. At this time, the circuit board 40 can output a signal matching the corresponding key 10 according to the different circuits that are turned on, so as to realize the signal input function of the keyboard 100.

[0155] Meanwhile, the elastic element 13 can accumulate elastic potential energy during the compression process. When the keycap 12 of the button 10 is released, the elastic element 13 can release the elastic potential energy and push the keycap 12 from the pressed position to the unpressed position. The elastic element 13 can also rebound to the state before being compressed, thereby disconnecting the circuit corresponding to the contact part 42. At this time, the circuit board 40 stops outputting signals.

[0156] The specific structure of the elastic element 13 is not limited here. In some implementations, such as... Figure 6 As shown, the elastic element 13 can be a silicone cap, which may have a protrusion facing the contact portion 42 of the circuit board 40. When the keycap 12 is pressed, the keycap 12 moves toward the circuit board 40, causing the keycap 12 to squeeze the silicone cap. Therefore, the protrusion of the silicone cap moves toward the circuit board 40 and squeezes the contact portion 42 of the circuit board 40, thus making the circuit corresponding to the contact portion 42 of the circuit board 40 conductive. In some other implementations, the elastic element 13 can also be a spring.

[0157] like Figure 6As shown, along the direction perpendicular to the thickness direction of the keyboard 100 (e.g.) Figure 6 In the Y direction, the base character portion 113 and the color-changing character portion 112 are located on opposite sides of the elastic member 13. The first light source 20 and the second light source 30 are located on opposite sides of the elastic member 13. The base character portion 113 and the second light source 30 are located on the same side of the elastic member 13. The elastic member 13 is coupled with visible light irradiating the color-changing character portion 112. Based on this, in some possible implementations, the elastic member 13 can be a light-transmitting elastic member. A light-transmitting elastic member can be understood as being made of a light-transmitting material, which can ensure that visible light passes through. The light-transmitting elastic member can transmit visible light to the color-changing character portion 112, ensuring that the color-changing character portion 112 emits light under the illumination of visible light. In addition, when the base character portion 113 and the second light source 30 are located on opposite sides of the light-transmitting elastic member, the light-transmitting elastic member can transmit visible light to the base character portion 113, causing the base character portion 113 to emit light.

[0158] In some possible implementations, such as Figure 6 As shown, the key 10 may also include a scissor-switch leg 14, which is disposed between the main board body 41 of the circuit board 40 and the keycap 12. A through hole is provided on the circuit board 40 at a position corresponding to the scissor-switch leg 14, allowing the scissor-switch leg 14 to pass through the circuit board 40 and support the keycap 12. The scissor-switch leg 14 includes a first support frame and a second support frame arranged in a cross configuration, forming an "X"-shaped support structure. This allows the scissor-switch leg 14 to support the keycap 12 in a translational motion during its up-and-down movement, improving the stability of the keycap 12's movement and preventing problems such as the keycap 12 lifting up or failing to press during the pressing process. Simultaneously, the scissor-switch leg 14 can provide a counterforce during the pressing of the keycap 12, creating a noticeable force feedback and improving the tactile feedback of the keycap 12 during pressing.

[0159] In order to prevent the scissor feet from obstructing visible light from illuminating the base character portion 113 and the color-changing character portion 112, and / or to obstruct invisible light from illuminating the color-changing character portion 112, in some possible implementations, the scissor feet 14 can be light-transmitting scissor feet. The light-transmitting scissor feet are made of light-transmitting material, and visible light and / or invisible light can pass through the light-transmitting scissor feet.

[0160] In the above description, the base character portion 113 emits light under the illumination of visible light emitted by the second light source 30. However, the base character portion 113 can also emit light under the illumination of a light beam in the environment in which the keyboard 100 is located, such as lamplight or sunlight. In addition, in some embodiments, the surface member 11 includes a plurality of character layers 111, and the character layer 111 farthest from the keycap 12 along the thickness direction X of the keyboard 100 includes the base character portion 113, which can improve the luminous effect of the base character portion 113.

[0161] In the above description, the base character portion 113 is made of non-color-changing ink. However, in some embodiments, the base character portion 113 may also be made of color-changing ink.
