Description

Technical Field

[0001] This application relates to the field of electronic information technology, and in particular to a visual button and a computer. Background Technology

[0002] With the development of electronic technology, many electronic products such as computers and remote controls require buttons for control or operation. However, in low-light conditions, buttons without visible markings are less visible and easier to operate. Summary of the Invention

[0003] This application aims to provide a visual button and computer, which improves the visibility and distinguishability of the button in a dark environment.

[0004] In a first aspect, this application proposes a visual button, including a pressing sheet, a light-diffusing sheet, and an FPC module. Specifically, the pressing sheet includes a first surface and a plurality of light-transmitting holes, the light-transmitting holes penetrating the first surface. The light-diffusing sheet is disposed on the first surface and covers the plurality of light-transmitting holes. The FPC module includes a button and an LED light group, the button and the LED light group being disposed facing the first surface, and the button being used to contact the light-diffusing sheet. Along a first direction, the projection of the LED light group falls into the projection of the light-diffusing sheet. The first direction is perpendicular to the first surface.

[0005] In the above solution, several light-transmitting holes are formed on the pressing plate, a light-diffusing sheet is set on the first surface, and an LED light group is set in the FPC module. The LED light group emits light, which passes through the light-diffusing sheet and thus emits visible light from the several light-transmitting holes on the pressing plate. This makes the button visible in a dark environment, improving its recognizability and ease of operation. Furthermore, the light passing through the light-diffusing sheet is characterized by uniform, soft light and minimal differences in brightness, which not only reduces eye strain from the visible button in a dark environment but also ensures uniform light emission from the several light-transmitting holes, making the visible image more recognizable.

[0006] In some embodiments, the visual button further includes a first support. The first support includes a second surface and a first through hole, the first through hole extending through the second surface along a first direction, and the first through hole includes a first opening disposed on the second surface. A light-diffusing sheet is disposed within the first through hole, and a pressing sheet is disposed within the first opening. By providing the first support, opening the first through hole, and disposing the light-diffusing sheet within the first through hole and the pressing sheet within the first opening, the stability of the visual button is improved.

[0007] In some embodiments, the light homogenizer includes a first light homogenizing layer and a second light homogenizing layer, which are stacked along a first direction. The axes of the first and second light homogenizing layers coincide, and the distance between the edge of the second light homogenizing layer and its axis is greater than the distance between the first light homogenizing layer and its axis, thus forming a stepped structure. The stepped structure reduces the non-working displacement of the light homogenizer in the first direction, thereby improving its stability and reducing the likelihood of it detaching.

[0008] In some embodiments, the second light-diffusing layer has a first groove, and the projection of the first groove falls within the projection of the first light-diffusing layer along the first direction. By creating the first groove, ensuring that its projection falls within the projection of the first light-diffusing layer, the problem of excessively long light propagation paths in the light-diffusing sheet can be reduced. Furthermore, the first groove prevents certain areas of the light-diffusing sheet from shrinking during processing due to excessive thickness, thus improving processing efficiency.

[0009] In some embodiments, the first bracket has a second through hole and a third through hole to form a second cantilever and a third cantilever. The axial directions of the second and third through holes are parallel to the axis of the first through hole. The second and third through holes are disposed opposite to each other on both sides of the first through hole, and the second and third cantilever are disposed opposite to each other on both sides of the first through hole. Forming the second and third cantilever by having the second and third through holes in the first bracket can improve the elasticity of the first bracket, increase the deformability of the first bracket in the first direction, and improve the comfort of pressing the visible buttons.

[0010] In some embodiments, the visual button further includes a second bracket. The FPC module is disposed on the second bracket and faces the first surface. Disposing of the FPC module on the second bracket improves the stability of the FPC module, resulting in more stable light emitted by the LED assembly and reducing light deviation caused by LED assembly displacement.

[0011] In some embodiments, along the second direction, the second bracket includes a first edge and a second edge disposed opposite to each other, the first edge having a first notch and a second notch. The first and second notches on the first edge of the second bracket are used for positioning and mounting the second bracket with an external device. This improves the ease of installation of the second bracket.

[0012] In some embodiments, the distance between adjacent light-transmitting holes is 0.38~0.40 mm, and the diameter of the light-transmitting holes is 0.18~0.20 mm. Setting the distance between adjacent light-transmitting holes to 0.38~0.40 mm and the diameter of the light-transmitting holes to 0.18~0.20 mm can improve the recognizability of the image formed after light passes through the light-transmitting holes.

[0013] In some embodiments, some of the light-transmitting holes are arranged in a ring shape, and the ring has a notch. Some of the light-transmitting holes are arranged in a straight line, with the line passing through the center of the ring and extending out of the notch. By arranging several light-transmitting holes in the above manner, the image effect of the light-formed pattern can be enhanced, and the recognizability of the pattern formed by the light-transmitting holes can be improved.

[0014] Secondly, this application proposes a computer including visual buttons as described in any embodiment of the first aspect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0020] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0021] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0022] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0023] Firstly, this application proposes a visual button, including a pressing sheet 1, a light-diffusing sheet 2, and an FPC module 3. Specifically, please refer to... Figures 1 to 5 The pressing plate 1 includes a first surface 11 and a plurality of light-transmitting holes 12, the light-transmitting holes 12 penetrating the first surface 11. A light-diffusing sheet 2 is disposed on the first surface 11 and covers the plurality of light-transmitting holes 12. The FPC module 3 includes a button 31 and an LED light group 32, both facing the first surface 11. The button 31 is used to contact the light-diffusing sheet 2. Along the first direction X, the projection of the LED light group 32 falls within the projection of the light-diffusing sheet 2. The first direction X is perpendicular to the first surface 11.

[0024] The press pad 1 can be made of metal, such as aluminum or aluminum alloy. Using aluminum alloy makes the press pad 1 lightweight and easy to press, and its surface can be anodized to give it a metallic finish, improving the user experience. Aluminum alloy also has good oxidation resistance, increasing the lifespan of the press pad 1. The light-transmitting holes 12 on the press pad 1 can be arranged in different ways depending on the design, improving visibility and convenience.

[0025] The light diffuser 2 can be made of materials such as acrylic or polycarbonate. The light diffuser 2 can reduce the direct light spot of the light source and disperse the concentrated light over a larger area, making the light brightness distribution more even. In addition, the microstructure of the light diffuser 2 (such as dot density and angle) can control the scattering direction of the light, so that the light is emitted at the designed angle, improving the light utilization rate and improving the visibility of the visible buttons.

[0026] The FPC module 3 is equipped with multiple electronic components. Among them, the button 31 is used to physically contact the light diffuser 2 to realize the switching function, and the LED light group 32 serves as a light source to provide illumination for the pressing plate 1. The LED light group 32 can be set as multiple independent light sources as needed, and multiple colors of light can be set, thereby improving the visibility of the visible buttons.

[0027] In the above scheme, several light-transmitting holes 12 are formed on the pressing plate 1, a light-diffusing sheet 2 is provided on the first surface 11, and an LED light group 32 is provided in the FPC module 3, so that the LED light group 32 emits light, and the light passes through the light-diffusing sheet 2 to emit visible light from the several light-transmitting holes 12 of the pressing plate 1. This makes the button visible in a dark environment, improving the visibility and ease of operation of the button in a dark environment. Furthermore, the light passing through the light-diffusing sheet 2 has the characteristics of uniform light, soft light, and small difference in brightness, which not only reduces eye stimulation of the visible button in a dark environment, but also makes the light emitted from the several light-transmitting holes 12 uniform, making the visible light image more recognizable.

[0028] In some embodiments, please refer to Figure 1 and Figure 6 The visual button also includes a first bracket 4. The first bracket 4 includes a second surface 41 and a first through hole 42. The first through hole 42 extends through the second surface 41 along a first direction X and includes a first opening 421 disposed on the second surface 41. A light-diffusing sheet 2 is disposed within the first through hole 42, and a pressing sheet 1 is disposed within the first opening 421. By setting the first bracket 4, opening the first through hole 42, and disposing the light-diffusing sheet 2 within the first through hole 42 and the pressing sheet 1 within the first opening 421, the stability of the visual button is improved.

[0029] In some embodiments, please refer to Figure 3The light-diffusing sheet 2 includes a first light-diffusing layer 21 and a second light-diffusing layer 22. Along the first direction X, the first light-diffusing layer 21 and the second light-diffusing layer 22 are stacked, with their axes coinciding. The distance between the edge of the second light-diffusing layer 22 and its axis is greater than the distance between the first light-diffusing layer 21 and its axis, thus forming a stepped structure. This stepped structure reduces the non-working displacement of the light-diffusing sheet 2 in the first direction X, thereby improving its stability and reducing the likelihood of it detaching.

[0030] In some embodiments, please refer to Figure 4 The second light-diffusing layer 22 has a first groove 23, and the projection of the first groove 23 falls within the projection of the first light-diffusing layer 21 along the first direction X. By creating the first groove 23, ensuring its projection falls within the projection of the first light-diffusing layer 21, the problem of excessively long light propagation paths in the light-diffusing sheet 2 can be reduced. Furthermore, the first groove 23 prevents certain areas of the light-diffusing sheet 2 from shrinking during processing due to excessive thickness, thus improving processing efficiency.

[0031] In some embodiments, please refer to Figure 6 The first bracket 4 has a second through hole 43 and a third through hole 44 to form a second cantilever 46 and a third cantilever. The axial directions of the second through hole 43 and the third through hole 44 are parallel to the axis of the first through hole 42. The second through hole 43 and the third through hole 44 are positioned opposite each other on both sides of the first through hole 42, and the second cantilever 46 and the third cantilever are also positioned opposite each other on both sides of the first through hole 42. Forming the second through hole 43 and the third through hole 44 in the first bracket 4 to form the second cantilever 46 and the third cantilever improves the elasticity of the first bracket 4, increases the deformability of the first bracket 4 in the first direction X, and improves the comfort when pressing the visible buttons.

[0032] In some embodiments, please refer to Figure 1 and Figure 7 The visible button also includes a second bracket 5. The FPC module 3 is mounted on the second bracket 5 and faces the first surface 11. Mounting the FPC module 3 on the second bracket 5 improves the stability of the FPC module 3, resulting in more stable light emitted by the LED light group 32 and reducing light deviation caused by the displacement of the LED light group 32. Furthermore, the LED light group 32 can include a first LED 321 and a second LED 322, making the light more uniform.

[0033] In some embodiments, please refer to Figure 7Along the second direction Y, the second bracket 5 includes a first edge 51 and a second edge 52 disposed opposite to each other. The first edge 51 has a first notch 53 and a second notch 54. The second direction Y is perpendicular to the first direction X. The first notch 53 and the second notch 54 on the first edge 51 of the second bracket 5 are used for positioning and installing the second bracket 5 with external equipment. This improves the ease of installation of the second bracket 5.

[0034] In some embodiments, the distance between adjacent light-transmitting holes 12 is 0.38mm to 0.40mm, and the diameter of the light-transmitting hole 12 is 0.18mm to 0.20mm. Setting the distance between adjacent light-transmitting holes 12 to 0.38mm to 0.40mm and the diameter of the light-transmitting hole 12 to 0.18mm to 0.20mm can improve the recognizability of the image formed after light passes through the light-transmitting hole 12.

[0035] In some embodiments, some of the light-transmitting holes 12 are arranged in a ring shape, and the ring has a notch. Some of the light-transmitting holes 12 are arranged in a straight line, with the straight line passing through the center of the ring and extending out of the notch. By arranging the light-transmitting holes 12 in the above manner, the image effect of the light forming a pattern can be enhanced, and the recognizability of the pattern formed by the light-transmitting holes 12 can be improved.

[0036] The visible buttons in this application maintain good visibility and legibility in dark environments. Please refer to [reference needed]. Figure 8 When the light emitted by the LED light group 32 passes through the light diffuser 2, the light diffuser 2 can improve the light path, so that the light passing through the light-transmitting hole 12 produces a more uniform lighting effect after refraction. Through the arrangement design of several light-transmitting holes 12, different lighting effects are produced on different buttons, so that users can have better visibility and recognition of different buttons in the dark.

[0037] Secondly, this application proposes a computer including visual buttons as described in any embodiment of the first aspect.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
