Description

Technical Field

[0001] This application relates to the field of electronic devices, and in particular to a button structure, a button, and an interactive flat panel. Background Technology

[0002] Display devices typically include a display screen and a bezel surrounding the display screen. The bezel usually has buttons installed so that users can control the display device by pressing the buttons.

[0003] To improve the accuracy of button presses, existing button designs typically place the button in the center and position the LEDs on either side. However, this design results in the center of the button being dimmer than the sides, affecting both display quality and overall aesthetics. Summary of the Invention

[0004] The purpose of this application is to provide a button structure, buttons, and interactive flat panel that can make the brightness of light emitted from different areas of the light-transmitting surface more uniform, thereby improving the display effect and overall aesthetics.

[0005] To achieve the above objectives, this application provides a button structure, which includes at least a button circuit board and a button body. The button circuit board has a button and a light-emitting element. The button body has an elastic reset element and a light-transmitting surface. The elastic reset element is connected to the button circuit board and covers the button and the light-emitting element. When subjected to external force, the elastic reset element presses the button through elastic deformation. The elastic reset element is made of a semi-transparent material. The light emitted by the light-emitting element is absorbed by the elastic reset element and then passes through the light-transmitting surface to the outside. The elastic reset element has a light-transmitting area, which is the area covered by the projection of the light-transmitting surface onto the elastic reset element along a direction perpendicular to the button circuit board. In the light-transmitting area, the thickness of the portion of the elastic reset element directly above the light-emitting element is greater than the thickness of the portion of the elastic reset element directly above the button.

[0006] The technical solution provided in this application features a semi-transparent elastic reset component. In the light-transmitting area, the thickness of the portion of the elastic reset component directly above the light-emitting component is greater than the thickness of the portion directly above the button. It is understood that the distance between the portion of the elastic reset component directly above the light-emitting component and the light-emitting component is closer than the distance between the portion directly above the button and the light-emitting component. Light gradually weakens with increasing distance during transmission. Therefore, this application increases the thickness of the portion of the elastic reset component closer to the light-emitting component and reduces the thickness of the portion farther away. A thicker semi-transparent material absorbs more light, making the light dimmer after passing through the material, while a thicker semi-transparent material absorbs less light, making the light brighter after passing through the material. This balances the problem of light gradually weakening with increasing distance during transmission, resulting in a more uniform brightness of light emitted from all areas of the light-transmitting surface, thereby improving the display effect and overall aesthetics.

[0007] Optionally, there are two light-emitting elements; the height of the button is greater than the height of the light-emitting elements; the button is located between the two light-emitting elements, and the button and the two light-emitting elements are arranged along the length of the button circuit board.

[0008] With the above solution, the top surface of the button is higher than the top surface of the light-emitting element. When the user presses the button with the elastic reset element, it can prevent the elastic reset element from contacting the light-emitting element and causing damage to the light-emitting element, thereby improving the service life of the product.

[0009] Optionally, the elastic reset member includes an abutting section and a deforming section; the deforming section surrounds the edge of the abutting section, extends toward the button circuit board and expands outward to form a raised space, and the abutting section is connected to the button circuit board through the deforming section; when the elastic reset member is connected to the button circuit board through the deforming section, the button and the two light-emitting elements are located within the raised space.

[0010] The above solution allows the deformation of the deformation section to move the contact section towards the button circuit board, thus pressing the button. When the pressing force is released, the contact section returns to its initial position under the elastic force of the deformation section, facilitating multiple pressing operations. Simultaneously, it avoids continuous contact between the contact section and the button, improving the accuracy and effectiveness of the pressing operation.

[0011] Optionally, the light-transmitting area is located in the abutting section; a groove is formed on the abutting section, the groove being located directly above the button, such that the thickness of the portion of the elastic reset member located directly above the two light-emitting elements is greater than the thickness of the portion of the elastic reset member located directly above the button.

[0012] The above-described solution results in a simple structure for the elastic reset component, which is easy to manufacture.

[0013] Optionally, the button body also has a pressing member; the pressing member is formed on the side of the abutting section away from the deforming section and fills the groove, the pressing member is made of transparent material, and the light-transmitting surface is located on the side of the pressing member away from the elastic reset member.

[0014] With the above solution, the pressing component covers the abutment section, and its surface can be made smooth, allowing users to press the elastic reset component and improving the pressing feel. At the same time, the pressing component is made of transparent material, which does not change the original light brightness, thus not affecting the balanced effect of the elastic reset component on the light emitted by the light-emitting component.

[0015] Optionally, the elastic reset member and the pressing member are formed by one of the following processes: two-color injection molding, two-stage injection molding, and overmolding injection molding.

[0016] With the above solution, the elastic reset component and the pressing component can be connected as one piece during production, eliminating the need for subsequent assembly.

[0017] Optionally, the groove is configured as a dovetail groove shape.

[0018] The above solution can increase the contact area between the elastic reset component and the pressing component, thereby increasing the contact strength between them.

[0019] Optionally, the bottom of the groove has a recess in the direction of the button, and the abutting section near the button has a corresponding pressing protrusion extending in the direction of the button; the pressing member has rigid properties and fills the area formed by the recess.

[0020] With the above solution, when the user presses the button, the feedback vibration force generated by the button reset can be effectively transmitted to the user's hand through the button, improving the pressing feel.

[0021] Optionally, the pressing member has a light guide portion on the side away from the elastic reset member; the light guide portion is integrally formed with the pressing member, the light guide portion is located in the middle of the pressing member, and the light guide portion extends along the length direction of the pressing member, and the light-transmitting surface is formed by the side of the light guide portion away from the pressing member; the key structure also includes a keycap, the keycap has a light guide hole corresponding to the light guide portion, when the keycap is fitted on the pressing member, the light guide portion passes through the light guide hole so that the light-transmitting surface is exposed on the keycap.

[0022] With the above solution, the light guide can be integrally molded with the pressing component to ensure that light can be effectively transmitted from the pressing component to the light guide. The light guide can be located in the middle of the pressing component to make the pressing component symmetrically arranged and improve its aesthetics.

[0023] Optionally, the button structure further includes a limiting bracket; the limiting bracket is supported on the button circuit board, and the limiting bracket is provided with a limiting hole corresponding to the keycap, and the keycap slides along the pressing direction under the limiting hole; the aspect ratio of the keycap is greater than 3:1.

[0024] The above solution guides the keycaps to slide smoothly through the limiting holes, reducing the possibility of keycap jamming and abnormal noises, and improving the user experience.

[0025] To achieve the above objectives, this application also provides a button, the button including an elastic reset member, wherein the elastic reset member is made of a semi-transparent material, the elastic reset member including an abutting section and a deformable section; a groove is formed in the middle of the abutting section, such that the thickness at both ends of the abutting section is greater than the thickness in the middle of the abutting section; the deformable section surrounds the edge of the abutting section, the deformable section extends downward and outward to form a raised space.

[0026] The technical solution provided in this application features a semi-transparent elastic reset component, with the thickness at both ends of the abutment section being greater than the thickness in the middle. It is understood that this application increases the thickness of the elastic reset component closer to the light-emitting element and reduces the thickness of the elastic reset component farther from the light-emitting element. A thicker semi-transparent material absorbs more light, making the light dimmer after passing through it, while a thicker semi-transparent material absorbs less light, making the light brighter after passing through it. This balances the problem of light gradually weakening with increasing distance during transmission, resulting in a more uniform brightness of light emitted from different areas of the light-transmitting surface, thereby improving the display effect and overall aesthetics.

[0027] Optionally, the button further includes a pressing element; the pressing element is formed on the side of the abutting section away from the deforming section and fills the groove; the pressing element has rigid properties, and the pressing element is formed by one of the processes of two-color injection molding, secondary injection molding, and overmolding.

[0028] Optionally, a light guide portion is provided on the side of the pressing member away from the elastic reset member; the light guide portion is integrally formed with the pressing member, and the light guide portion is located in the middle position of the pressing member.

[0029] To achieve the above objectives, this application also provides an interactive flat panel, which includes a frame and the aforementioned button structure; the frame is provided with a clearance hole, the button structure is installed in the frame, and a portion of the button structure extends out from the clearance hole.

[0030] Optionally, the interactive flat panel further includes a mounting bracket; the mounting bracket is connected to the frame, and the button circuit board of the button structure is mounted on the mounting bracket.

[0031] In summary, the interactive flat panel provided in this application embodiment has the advantage of making the brightness of light emitted from each area of ​​the light-transmitting surface tend to be uniform, thereby improving the display effect and overall aesthetics.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Terms used in this application to indicate spatial relative positions, such as “above,” “over,” “below,” “under,” “first end,” “second end,” “one end,” and “other end,” are used for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” other units or features would be located “above” other units or features. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0046] Furthermore, the terms "installation," "setup," "equipped with," "connection," "sliding connection," "fixed," and "sleeve connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] Display devices typically include a display screen and a bezel surrounding the display screen. The bezel usually has buttons installed so that users can control the display device by pressing the buttons.

[0048] Existing button structures typically include a button circuit board, a button body, and keycaps. The button circuit board houses the button and LEDs. To improve the accuracy of press control, the button is usually positioned in the center, with the LEDs on either side. When both LEDs are lit, the light emitted by the two LEDs travels a greater distance to the center of the light-transmitting surface of the button structure than to the ends. This results in the center of the button structure being dimmer than the sides, affecting the display effect and compromising the overall aesthetics.

[0049] To address the aforementioned issues, the inventors of this application attempted to make the button body a semi-transparent material. This would allow the semi-transparent material to absorb, scatter, or refract some of the light emitted by the LED, thus reducing the brightness difference between the center and ends of the button's translucent surface. However, some brightness still needs to be retained at the translucent surface of the button to guide the user in locating the button for pressing. Therefore, the above method is not very effective in improving the brightness difference between the center and ends of the button's translucent surface.

[0050] Based on this, this application further improves upon the semi-transparent material used for the button body. Specifically, the thickness of the semi-transparent button body corresponding to the light-transmitting surface is adjusted according to its distance from the LED light. That is, the thickness of the semi-transparent button body portion corresponding to the light-transmitting surface and closer to the LED light is greater than the thickness of the semi-transparent button body portion corresponding to the light-transmitting surface and farther from the LED light. Since a thicker semi-transparent material absorbs more light, the light becomes dimmer after passing through the material. Therefore, by varying the light absorption of the semi-transparent portions with different thicknesses, the brightness of the light emitted from the light-transmitting surface can be made more uniform, thereby improving the display effect and the overall aesthetics of the display device. Furthermore, to ensure the flatness of the light-transmitting surface of the button body, an additional transparent layer can be attached to the semi-transparent portion of the button body to improve its appearance.

[0051] In addition, to further improve the vibration effect of button feedback, the inventors of this application have also given the transparent part of the button body a rigid material property, so that the vibration force of the button feedback can be effectively transmitted to the user's hand through the transparent part, thereby improving the pressing feel.

[0052] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0053] This application provides a button structure for use in electronic devices. Users control the display device by pressing the button structure, such as turning the electronic device on or off, switching pages, or adjusting volume. This application does not specifically limit the application to these functions. The electronic device can be a smart screen, interactive flat panel, or smart blackboard, etc.

[0054] For details, please refer to the following: Figures 1 to 3 In one feasible implementation, the button structure may include at least a button circuit board 100 and a button body 200. The button circuit board 100 is a circuit board for controlling button operation, and typically includes a button 110 and a light-emitting element 120. Control operation is achieved by pressing the button 110. The light-emitting element 120 emits light to guide the user to the location of the button structure. And / or, the light-emitting element 120 changes color in response to the control operation of the button 110 to indicate the current status. For example, when the button 110 of the button structure is pressed to close the interactive panel, the interactive panel is in the closed state, and the light-emitting element 120 displays red; when the button 110 of the button structure is pressed to open the interactive panel, the interactive panel is in the open state, and the light-emitting element 120 displays green. In practical applications, the light-emitting element 120 can be an LED light, a fluorescent tube, or a xenon lamp, etc.

[0055] The button body 200 has an elastic reset element 210 and a light-transmitting surface 220. The elastic reset element 210 is connected to the button circuit board 100 and covers the button 110 and the light-emitting element 120. The elastic reset element 210 is elastically deformable. When subjected to external force, the elastic reset element 210 can press the button 110 through elastic deformation, and when the external force disappears, the elastic reset element 210 returns to its initial state for the next press operation. The elastic reset element 210 has semi-transparent properties, meaning it allows a certain degree of light to pass through, but also allows a certain degree of reflection or scattering. The elastic reset element 210 can be made of semi-transparent rubber or semi-transparent silicone material. The light emitted by the light-emitting element 120 is absorbed by the elastic reset element 210 and then passes through the light-transmitting surface 220 to the outside. In other words, the elastic reset element 210 can absorb part of the light emitted by the light-emitting element 120, and the remaining light after absorption can pass through the light-transmitting surface 220 to the outside. In this way, the light emitted from the light-transmitting surface 220 to the outside can be softer, reducing the glare and improving user comfort. It should be noted that the light-transmitting surface 220 as defined in this application refers to the plane exposed on the outside of the button body 200 through which the light emitted by the light-emitting element 120 must pass to reach the outside.

[0056] In this embodiment, the elastic reset member 210 has a light-transmitting area, which is the area covered by the projection of the light-transmitting surface 220 onto the elastic reset member 210 along a direction perpendicular to the button circuit board 100. In the light-transmitting area, the thickness of the portion of the elastic reset member 210 located directly above the light-emitting element 120 is greater than the thickness of the portion of the elastic reset member 210 located directly above the button 110. It is understandable that the distance between the portion of the elastic reset member 210 located directly above the light-emitting member 120 and the light-emitting member 120 is closer than the distance between the portion of the elastic reset member 210 located directly above the button 110 and the light-emitting member 120. As light gradually weakens with increasing distance during transmission, by increasing the thickness of the portion of the elastic reset member 210 closer to the light-emitting member 120 and thinning the portion of the elastic reset member 210 farther from the light-emitting member 120, the thicker semi-transparent material will absorb more light, making the light dimmer after passing through the material. This balances the problem of light gradually weakening with increasing distance during transmission, thereby making the brightness of the light emitted from each area of ​​the light-transmitting surface 220 more uniform, thus improving the display effect and overall aesthetics.

[0057] It should be noted that the light emitted from the light-transmitting surface 220 is conducted through the area covered by the projection of the light-transmitting surface 220 onto the elastic reset member 210 along a direction perpendicular to the button circuit board 100, i.e., the light-transmitting area, and thus emitted to the outside from the light-transmitting surface 220. Light conducted along other areas cannot be emitted to the outside from the light-transmitting surface 220, meaning it does not affect the brightness of the light emitted from each area of ​​the light-transmitting surface 220. Therefore, this application specifically limits the thickness of the elastic reset member 210 within the area covered by the projection of the light-transmitting surface 220 onto the elastic reset member 210 along a direction perpendicular to the button circuit board 100, while not specifically limiting the thickness of the elastic reset member 210 in other areas.

[0058] In practical applications, the elastic reset element 210 can be made of a semi-transparent material to allow it to absorb light. The thickness of the elastic reset element 210 located directly above the light-emitting element 120 can vary in thickness from that of the elastic reset element 210 located directly above the button 110. Alternatively, the thickness of the elastic reset element 210 located directly above the light-emitting element 120 can also gradually change towards that of the elastic reset element 210 located directly above the button 110, further enhancing the uniformity of light brightness emitted from different areas of the light-transmitting surface.

[0059] In one feasible implementation, the light-emitting element 120 may be a single unit. The button 110 is located in the middle of the elastic reset member 210 for easy pressing operation, and the light-emitting element 120 is located on one side of the button 110.

[0060] In one feasible implementation, the light-emitting element 120 may have two, and the button 110 is located in the middle of the elastic reset element 210 to facilitate pressing operation. The button 110 is located between the two light-emitting elements 120.

[0061] In practical applications, the button 110 and the two light-emitting elements 120 can be arranged along the length of the button circuit board 100 to make the arrangement of the button 110 and the two light-emitting elements 120 on the button circuit board 100 more balanced. The height of the button 110 should be greater than the height of the light-emitting elements 120. This way, the top surface of the button 110 is higher than the top surface of the light-emitting elements 120. When the user presses the button 110 using the elastic reset element 210, it can prevent the elastic reset element 210 from contacting the light-emitting element 120 and causing damage, thus improving the product's lifespan.

[0062] It is worth mentioning that, in order to more intuitively demonstrate that the brightness of the light emitted from each area of ​​the light-transmitting surface 220 is more balanced than before the improvement, this application uses an example where there are two light-emitting elements 120, the button 110 is located in the middle of the elastic reset element 210, and the total length of the light-transmitting surface 220 is 11cm. The brightness curves of each area of ​​the light-transmitting surface 220 before and after the improvement are measured (see Figure 4). As can be seen from the figure, the difference between the brightness values ​​at both ends of the improved light-transmitting surface 220 and the brightness value in the middle is about 1 / 6 less than before. The brightness of the light emitted from each area of ​​the light-transmitting surface 220 is more balanced, with no significant difference.

[0063] For details regarding the structure of the elastic reset element 210, please refer to [link / reference needed]. Figure 3 and Figure 5 As shown, in one feasible embodiment, the resilient reset member 210 may include an abutting section 211 and a deformable section 212. The abutting section 211 is generally parallel to the button circuit board 100, and the deformable section 212 surrounds the edge of the abutting section 211, extending towards the button circuit board 100 and expanding outward to form a raised space 213. The abutting section 211 is connected to the button circuit board 100 through the deformable section 212. Furthermore, when the abutting section 211 is connected to the button circuit board 100 through the deformable section 212, the button 110 and the light-emitting element 120 are located within the raised space 213.

[0064] In this embodiment, the abutting section 211 and the deformation section 212 can be made of elastic materials, such as translucent rubber or translucent silicone. When the user presses the elastic reset member 210, the user's pressing force acts on the abutting section 211, which transmits the force to the deformation section 212. The deformation section 212 deforms, allowing the abutting section 211 to move towards the button circuit board 100 to press the button 110. When the pressing force disappears, the abutting section 211 returns to its initial position under the elastic force of the deformation section 212, facilitating multiple pressing operations. Simultaneously, continuous contact between the abutting section 211 and the button 110 can be avoided, improving the accuracy and effectiveness of the pressing operation.

[0065] In practical applications, the abutment section 211 and the deformation section 212 can be integrally formed, or they can be designed separately and then connected to each other.

[0066] In one feasible implementation, the elastic reset member 210 may further include a fixed segment 214 connected to the end of the deformable segment 212 away from the abutting segment 211. The fixed segment 214 at least partially surrounds the outer edge of the abutting segment 211 and extends horizontally outward from the deformable segment 212. The deformable segment 212 is connected to the button circuit board 100 through the fixed segment 214.

[0067] In this embodiment, a pull tab 215 may be formed on the fixing segment 214, and a snap-fit ​​hole corresponding to the position of the pull tab 215 is formed on the button circuit board 100. The fixing segment 214 is connected to the button circuit board 100 by snapping the pull tab 215 into the snap-fit ​​hole. The pull tab 215 can be understood as an elastic protrusion. The size of the protrusion in its normal state is larger than that of the snap-fit ​​hole, so as to snap it into the snap-fit ​​hole using its own elasticity.

[0068] In practical applications, two pull tabs 215 can be provided, with the two pull tabs 215 located at both ends of the elastic reset member 210 along its length. This improves the connection stability between the elastic reset member 210 and the button circuit board 100. The pull tab 215, the fixing section 214, the abutting section 211, and the deformation section 212 can be integrally formed, or they can be designed separately and then connected to each other.

[0069] Please see again Figure 5As shown, in one feasible embodiment, the area covered by the orthogonal projection of the light-transmitting surface 220 onto the elastic reset member 210 along a direction perpendicular to the button circuit board 100 is located in the abutting section 211, that is, the light-transmitting area is located in the abutting section 211. Accordingly, by forming a groove 2111 on the abutting section 211, with the groove 2111 located directly above the button 110, the thickness of the portion of the elastic reset member 210 located directly above the two light-emitting elements 120 is greater than the thickness of the portion of the elastic reset member 210 located directly above the button 110.

[0070] Of course, it can also be understood that by forming a protruding structure in the direction away from the button circuit board 100 on the abutting section 211 directly above the two light-emitting elements 120 respectively, the thickness of the portion of the elastic reset member 210 located directly above the two light-emitting elements 120 is greater than the thickness of the portion of the elastic reset member 210 located directly above the button 110.

[0071] Because the abutment section 211 of the elastic reset member 210 has a groove 2111, the abutment section 211 is uneven. If the user presses the abutment section 211 directly, it will inevitably affect the user experience. In order to make the surface pressed by the user smoother and not affect the uniform effect of the elastic reset member 210 on the light emitted by the light-emitting member 120, please refer to... Figure 3 and Figure 6 As shown, in one feasible embodiment, the button body 200 may further include a pressing member 230. The pressing member 230 is formed on the side of the abutting section 211 away from the deformable section 212, and is transparent. Thus, the pressing member 230 can cover the abutting section 211, and its surface can be made smooth, allowing the user to press the elastic reset member 210. Simultaneously, the pressing member 230 is made of a transparent material, thus maintaining its transparency and not altering the original light brightness, thereby not affecting the balanced effect of the elastic reset member 210 on the light emitted by the light-emitting element 120. Correspondingly, the light-transmitting surface 220 should be located on the side of the pressing member 230 away from the elastic reset member 210.

[0072] It should be noted that the pressing part 230 should fill the groove 2111. This ensures that the part of the button body 200 corresponding to the button 110 has sufficient strength, and avoids that the button body 200 will deform significantly when the button 110 is pressed, thus affecting the accuracy and effectiveness of the pressing operation.

[0073] In practical applications, to simplify assembly, the elastic reset component 210 and the pressing component 230 can be molded using one of the following methods: two-color injection molding, two-stage injection molding, or overmolding. This allows the elastic reset component 210 and the pressing component 230 to be integrated during production, eliminating the need for subsequent assembly. Alternatively, the elastic reset component 210 and the pressing component 230 can also be connected using methods such as adhesive bonding or heat fusion.

[0074] To improve the bonding strength between the elastic reset member 210 and the pressing member 230, please refer again. Figure 3 and Figure 5 As shown, in one feasible embodiment, the groove 2111 can be constructed as a dovetail groove. This increases the contact area between the elastic reset member 210 and the pressing member 230, thereby increasing their contact strength. Furthermore, since the portion of the elastic reset member 210 is located above the portion of the pressing member 230, it can bear some of the force, thus reducing the stress on the contact surface between the elastic reset member 210 and the pressing member 230, further improving their contact stability.

[0075] Of course, based on the dovetail groove shape of the groove 2111, some additional connecting protrusions can be added to increase the contact area with the pressing member 230, thereby increasing the bonding strength between the elastic reset member 210 and the pressing member 230. However, it should be noted that the additional connecting protrusions should not be located in the area covered by the projection of the light-transmitting surface 220 onto the elastic reset member 210 along the direction perpendicular to the button circuit board 100, so as to avoid affecting the brightness balance effect of each area in the light-transmitting surface 220.

[0076] Please see again Figure 3 and Figure 6 In one feasible embodiment, the bottom of the groove 2111 is recessed towards the button 110, and a pressing protrusion 2112 extending towards the button 110 is correspondingly formed on the side of the abutment section 211 near the button 110. This allows the elastic reset member 210 to contact and press against the button 110 via the pressing protrusion 2112, avoiding misalignment caused by pressing against the button 110 via the abutment section 211, thus improving the sensitivity and accuracy of the pressing operation. Simultaneously, the pressing member 230 possesses rigid characteristics and fills the area formed by the recess. When the user presses the pressing member 230, the feedback vibration force generated by the button 110's reset can be effectively transmitted to the user's hand through the pressing member 230, improving the pressing feel.

[0077] In practical applications, the pressing element 230 can be made of a material with rigid properties, such as PC or PVC.

[0078] Please see Figure 6 and Figure 7 As shown, a light guide portion 231 is provided on the side of the pressing member 230 away from the elastic reset member 210. At this time, the light-transmitting surface 220 is formed by the side of the light guide portion 231 away from the pressing member 230. In this embodiment, the light guide portion 231 can be integrally formed with the pressing member 230 to ensure that light can be effectively transmitted from the pressing member 230 to the light guide portion 231.

[0079] In practical applications, the light guide 231 can be located in the middle of the pressing member 230 to make the pressing member 230 symmetrically arranged and improve the aesthetics. The shape of the light guide 231 can be circular, square, or rectangular, etc. Taking the light guide 231 as a rectangular shape as an example, the light guide 231 can extend along the length direction of the pressing member 230.

[0080] In one feasible implementation, the key structure may further include a keycap 300, which is used to fit onto the pressing member 230. The keycap 300 is provided with a light guide hole 310 corresponding to the light guide portion 231. When the keycap 300 is fitted onto the pressing member 230, the light guide portion 231 passes through the light guide hole 310, so that the light-transmitting surface 220 is exposed on the keycap 300, thereby allowing light emitted from the light-transmitting surface 220 to be emitted to the outside, while the remaining light is blocked inside the key structure.

[0081] In practical applications, the top surface of keycap 300 should be flush with the backlit surface 220 to prevent a height difference between the sides in contact with the user from affecting the user experience. The top edge of keycap 300 can be slightly curved to improve the typing feel.

[0082] Due to aesthetic requirements, keycaps 300 are typically constructed in a long, rectangular shape, meaning their aspect ratio is greater than 3:1. However, when using elongated keycaps 300, pressing one corner causes the other end to lift up, hitting the side wall of the mounted component and causing key jamming and unusual noises, affecting the pressing operation and tactile feedback.

[0083] To solve the above problems, please refer to... Figure 7 and Figure 8 As shown, in one feasible implementation, the key structure may further include a limiting bracket 400, which is supported on the key circuit board 100. The limiting bracket 400 has a limiting hole 410 corresponding to the keycap 300, and the keycap 300 slides along the pressing direction under the limiting of the limiting hole 410. In this way, the keycap 300 is guided to slide by the limiting hole 410, reducing the possibility of the keycap 300 getting stuck and making abnormal noises, thus improving the user experience.

[0084] In this embodiment, the gap between the outer wall of the keycap 300 and the inner wall of the limiting hole 410 should be as small as possible to reduce the inclination of the keycap 300. Moreover, the thickness of the limiting bracket 400 should be as thin as possible to reduce the contact area between the keycap 300 and the limiting bracket 400 when the keycap 300 inclines, thus avoiding key jamming.

[0085] In practical applications, the limiting bracket 400 can be configured in a "U" shape. The limiting hole 410 is formed at the middle position of the top of the limiting bracket 400, and the limiting bracket 400 is connected and fixed through both ends of the bottom.

[0086] Based on the same inventive concept, please refer to Figure 5 and Figure 6 As shown, the present application further provides a key, which includes an elastic reset member 210. The elastic reset member 210 is made of a translucent material and includes an abutting section 211 and a deformation section 212. A groove 2111 is formed at the middle position of the abutting section 211, so that the thicknesses at both ends of the abutting section 211 are greater than the middle thickness of the abutting section 211. The deformation section 212 surrounds the edge of the abutting section 211, and the deformation section 212 extends downward and expands outward to form a raised space 213.

[0087] Furthermore, the key further includes a pressing member 230. The pressing member 230 is formed on the side of the abutting section 211 away from the deformation section 212, and the pressing member 230 fills the groove 2111. The pressing member 230 has a hard property and is formed by one of the processes of two-color injection molding, secondary injection molding, and overmolding.

[0088] Furthermore, a light guide portion 231 is provided on the side of the pressing member 230 away from the elastic reset member 210. The light guide portion 231 is integrally formed with the pressing member 230, and the light guide portion 231 is located at the middle position of the pressing member 230.

[0089] It should be noted that for the specific structures of the elastic reset member 210 and the pressing member 230, reference may be made to the content in the above embodiments, which will not be elaborated here.

[0090] Based on the same inventive concept, please refer to Figure 9 and Figure 10 As shown, the present application provides an interactive flat panel, which includes a frame 500 and the above key structure. The frame 500 is provided with a relief hole 510, and the key structure is installed in the frame 500, and a part of the key structure protrudes from the relief hole 510 to facilitate the user to press the key structure.

[0091] It should be noted that for the specific structure of the key structure, reference may be made to the content in the above embodiments, which will not be elaborated here.

[0092] In one possible implementation, the interactive flat panel further includes a mounting bracket 600. The mounting bracket 600 is connected to the frame 500, and the button circuit board 100 with a button structure is mounted on the mounting bracket 600.

[0093] In practical applications, the button structure can be mounted on the mounting bracket 600 using screws or other methods. Then, the button structure extends into the frame 500, and finally, the mounting bracket 600 is connected to the outer wall of the frame 500. This transforms internal connection operations into external connection operations, facilitating assembly.

[0094] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
