Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an electronic device. Background Technology

[0002] With the development of communication technology, electronic devices such as mobile phones and tablets have become indispensable tools for people. When faced with a dazzling array of electronic devices, users not only need to consider whether the functions of the devices meet their needs, but also the appearance of the devices is one of the important factors influencing consumers' purchasing decisions. In order to enrich the appearance of electronic devices, they are equipped with light-emitting components, which enhance their visual appeal.

[0003] In related technologies, mounting holes are typically made on the decorative components of electronic devices, and the light source of the light-emitting component is correspondingly arranged at the mounting hole so that light can pass through the mounting hole, thereby achieving a light-emitting effect in the decorative component area and thus optimizing the overall appearance of the electronic device.

[0004] However, in actual structural design, the light-emitting components need to reserve space for other functional structures and assembly structures on the decorative components. Therefore, due to the constraints of structural layout, the effective light-emitting surface size of the light-emitting components is difficult to increase, which directly leads to insufficient light-emitting brightness, limited light-emitting area, and weak light-emitting effect of electronic devices, ultimately resulting in poor light-emitting performance of electronic devices. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device that can solve the technical problem of poor light-emitting performance of electronic devices.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows: This application discloses an electronic device, including: case; The decorative component includes a decorative body, a lens, and a semi-permeable membrane. The decorative body is disposed on the housing. The decorative body has a first through hole. The lens is installed on the side of the decorative body away from the housing and surrounds the decorative body to form a receiving cavity. The semi-permeable membrane is disposed in at least a portion of the lens. A camera module, at least a portion of which is disposed within the housing, wherein the lens of the camera module is disposed opposite to the first through hole; The system includes a light source, a light guide, and a diffuser, with the light guide and diffuser both located within the receiving cavity. The lens, diffuser, light guide, and decorative body are stacked along a first direction. The light guide has a second and a third through-hole, and the diffuser has a fourth through-hole. The third and fourth through-holes are opposite to the first through-hole. At least a portion of the light source is located within the second through-hole, and the emitting side of the light source is opposite to the wall of the second through-hole. The light guide has multiple reflective microstructures, and the distribution density of the reflective microstructures in a direction perpendicular to the first direction is positively correlated with the distance between the light sources. When the light source is in operation, the light is emitted after passing through the light guide, the diffuser and the semi-permeable membrane.

[0007] In this embodiment, both the light guide and the diffuser are located within the cavity formed by the decorative body and the lens. The lens, diffuser, light guide, and decorative body are stacked along a first direction. The light guide has a second through hole, and at least a portion of the light source is located within the second through hole. The light-emitting side of the light source is positioned opposite to the wall of the second through hole. The light guide has multiple reflective microstructures, and the distribution density of the reflective microstructures is positively correlated with the distance between the light sources in a direction perpendicular to the first direction. In this scheme, the reflective microstructures on the light guide with increasing density at the distance to the light source, combined with the stacked diffuser, form a two-stage uniform light path. First, the reflective microstructures with increasing density at the distance to the light source can compensate for the light energy attenuation at the far end of the light guide, thereby improving the light energy utilization rate and improving the uneven brightness of the light source in areas closer to and farther from the light source, as well as the poor brightness in distant areas. This widens the lateral light-emitting coverage area, thus achieving a large-area light-emitting effect except for the area where the camera module is located. Furthermore, the light emitted through the reflective microstructure is diffused by the diffuser, further eliminating bright and dark stripes and localized light spots caused by the sparse and dense arrangement of the reflective microstructure, thereby smoothing out the brightness difference between near and far areas and further improving the uniformity of light emission. Therefore, under the synergistic effect of the diffuser and the gradient density reflective microstructure, while reserving space for clearance and constrained by the structural layout, the requirements for clearance between the assembly and the camera module are met, while maximizing the effective light-emitting surface, increasing the brightness of the emitted light, and improving the uniformity of light emission. This overcomes the inherent contradiction between traditional structural clearance and light emission performance, thus effectively improving the luminous performance of electronic devices.

Detailed Implementation

[0010] 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 only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0013] Please refer to Figures 1 to 14 This application discloses an electronic device, which includes a housing 100, a decorative component 200, a camera module 400, a light source 310, a light guide 320, and a diffuser 330.

[0014] The housing 100 is the external component of the electronic device and also provides a mounting base for other components of the electronic device. The housing 100 has an inner cavity and mounting holes communicating with the inner cavity. The inner cavity is the space within the housing 100 for mounting functional components of the electronic device. For example, circuit boards, motherboard brackets, camera modules 400, and other components of the electronic device are mounted in the inner cavity. The mounting holes are formed on the housing wall of the housing 100 to expose some functional components. In this application, the mounting holes are used to expose the camera module 400.

[0015] In one embodiment, the housing 100 may include a frame and a back cover, where the back cover can also be understood as a battery cover, and the frame is the side of the housing 100. The frame surrounds the battery cover, and in this case, the frame has a ring structure, connecting to the outer edge of the battery cover. The frame and the battery cover together form the aforementioned inner cavity. This can be understood as the frame and the battery cover forming a recessed portion, so the inner cavity is essentially a recessed portion. This recessed portion is the inner cavity of the housing 100. The display screen of the electronic device in this application can be located on the side of the frame away from the battery cover. This can also be understood as the display screen being located on the side of the opening of the recessed portion, thereby making the recessed portion a closed structure.

[0016] In another embodiment, the housing 100 may include a front cover, a frame, and a rear cover, with the frame located between the front and rear covers. The frame, front cover, and rear cover together enclose the aforementioned inner cavity. The display screen of the electronic device in this application may be disposed on the front cover. Of course, the housing 100 is not limited to the structure in this application and may also be other structures. This is not a limitation herein. In other embodiments of this application, the electronic device further includes a display screen assembly, which may be mounted on the housing 100.

[0017] The aforementioned mounting holes can be made on the rear cover. Of course, the mounting holes are not limited to the rear cover and can also be made in other locations on the housing 100. This article does not impose any restrictions on this.

[0018] The camera module 400 is used to realize the shooting function of the electronic device. At least a portion of the camera module 400 is disposed within the housing 100. Specifically, at least a portion of the camera module 400 can be located within the inner cavity of the housing 100. The camera module 400 is opposite to the mounting hole on the housing 100, and the lens of the camera module 400 is exposed.

[0019] A decorative component 200 is mounted on the housing 100 to conceal and decorate the camera module 400. The decorative component 200 includes a decorative body 210 and a lens 220. The decorative body 210 is disposed on the housing 100 and specifically mounted in a mounting hole. The decorative body 210 is the main component of the decorative component 200, providing a mounting base for other structures within the decorative component 200. Simultaneously, the decorative body 210 also serves as the primary concealing element. To expose the lens of the camera module 400, the decorative body 210 has a first through-hole 211, with the lens of the camera module 400 positioned opposite to the first through-hole 211. At this time, at least a portion of the lens of the camera module 400 can pass through the first through-hole 211. Alternatively, the lens of the camera module 400 can be located outside the first through-hole 211, only opposite to it. Here, the first through-hole 211 serves to avoid obstructing the lens of the camera module 400.

[0020] The lens 220 is mounted on the side of the decorative body 210 away from the housing 100, at which point the lens 220 is supported on the decorative body 210. The lens 220 and the decorative body 210 enclose and form a receiving cavity 201. At this time, a cavity is formed between the lens 220 and the decorative body 210.

[0021] The light source 310, light guide 320, and diffuser 330 are all located within the receiving cavity 201. At this time, the light guide 320 and diffuser 330 are positioned between the lens 220 and the decorative body 210. Specifically, the lens 220, diffuser 330, light guide 320, and decorative body 210 are stacked along a first direction Z. Here, the first direction Z can be the thickness direction of the decorative component 200, or it can be understood as a direction perpendicular to the plane where the lens 220 is located.

[0022] The light guide 320 is used to transmit light. Specifically, the light guide 320 has a second through hole 3201 and a third through hole 3202, and the diffuser 330 has a fourth through hole 331. The third through hole 3202 and the fourth through hole 331 are arranged opposite to the first through hole 211. Since the light guide 320 is located between the lens 220 and the decorative body 210, in order to avoid obstructing the camera module 400, the light guide 320 and the diffuser 330 need to have through holes opposite to the first through hole 211, thereby avoiding obstructing the lens of the camera module 400.

[0023] At least a portion of the light-emitting source 310 is located within the second through-hole 3201, which is used to accommodate the light-emitting source 310. The light-emitting side of the light-emitting source 310 is disposed opposite to the wall of the second through-hole 3201, which can be understood as the light-incident surface of the light guide 320. The light guide 320 is provided with a plurality of reflective microstructures 3203. In a direction perpendicular to the first direction Z, the distribution density of the reflective microstructures 3203 is positively correlated with the distance between the light-emitting sources 310. At this time, the plane on which the light guide 320 is located can be perpendicular to the first direction Z. Therefore, the plurality of reflective microstructures 3203 are arranged at intervals on the plane on which the light guide 320 is located, and the distribution density of the reflective microstructures 3203 on the plane on which the light guide 320 is located is positively correlated with the distance between the light-emitting sources 310. In other words, the density of reflective microstructures 3203 is lower in the region of the plane containing the light guide 320 that is closer to the light source 310, and higher in the region of the plane containing the light guide 320 that is farther from the light source 310. These reflective microstructures 3203 can be disposed on the surface of the light guide 320 facing the lens 220, or on the surface of the light guide 320 away from the lens 220. Therefore, the opposing surfaces of the light guide 320 arranged along the first direction Z can both serve as the plane containing the light guide 320.

[0024] In specific operation, when the light source 310 is in working condition, it is illuminated. Light enters the light guide 320 through the sidewall 3721 of the second through hole 3201, and exits from the lens 220 only after passing through the light guide 320 and the diffuser 330. This can be understood as the lens 220 being transparent except for the area opposite the first through hole 211, thus serving as a light-emitting area. Therefore, when the light source 310 is in working condition, only the area of ​​the lens 220 opposite the first through hole 211 is illuminated. Alternatively, an outer ring light-emitting area can be reserved on the lens 220, meaning only the outer ring is transparent, while the inner ring of the lens 220 is light-blocked, forming an annular light-emitting area at the edge of the lens 220. Therefore, when the light source 310 is in working condition, the edge area of ​​the lens 220 is illuminated.

[0025] In the embodiments disclosed in this application, the reflective microstructures 3203 on the light guide 320, whose density increases with the distance from the light source 310, are combined with the stacked diffuser 330 to form a two-stage uniform light path. First, the reflective microstructures 3203, whose density increases with the distance from the light source 310, can compensate for the light energy attenuation at the far end of the light guide 320, thereby improving the light energy utilization rate and improving the problem of uneven light emission brightness in areas closer to and farther from the light source 310, as well as the problem of poor light emission brightness in distant areas. This can further widen the lateral light emission coverage area, so as to achieve the effect of large-area light emission except for the setting area of ​​the camera module 400. In addition, the light emitted by the reflective microstructures 3203 is diffused by the diffuser 330, further eliminating the bright and dark stripes and local light spots caused by the density of the reflective microstructures 3203, thereby further smoothing out the brightness difference between near and far areas, and further improving the uniformity of the emitted light. Therefore, under the synergistic effect of the diffuser 330 and the reflective microstructure 3203 with gradient density, while reserving space for avoidance and being constrained by the structural layout, the avoidance requirements of the assembly and camera module 400 are met, and the effective light-emitting surface is maximized, the light-emitting brightness is increased, and the light-emitting uniformity is improved. This overcomes the inherent contradiction between traditional structural avoidance and light-emitting performance, and thus effectively improves the light-emitting performance of electronic devices.

[0026] Furthermore, the light emitted from the light source 310 into the light guide 320 can be cross-premixed by the reflective microstructure 3203, and then further diffused and mixed via the diffuser 330. Therefore, the reflective microstructure 3203, whose density increases with the distance from the light source 310, combined with the stacked diffuser 330, has good light mixing performance, thus eliminating the need for a long light mixing region in the light guide 320. Therefore, in the embodiments of this application, the light source 310 can be directly disposed within the second through-hole 3201 on the light guide 320. At least a portion of the light source 310 is embedded within the light guide 320, which helps to reduce the stacking size between the light source 310 and the light guide 320, thereby facilitating the thinning and lightening of electronic devices.

[0027] In addition, at least a portion of the light source 310 is embedded in the light guide 320, which makes the light source 310 closer to the light emission area, thus retaining the maximum light emission brightness, which is beneficial to further improve the light emission brightness of the electronic device.

[0028] In this application, a clearance hole may be provided in the area opposite to the second through hole 3201 of the diffuser 330; of course, it is also possible not to provide a clearance hole. This document does not impose any restrictions on this.

[0029] In this application, the lens 220 is completely transparent and unobstructed. When viewed directly from the outside, the boundary of the diffuser 330, the fine surface haze, the pressing wrinkles, the cutting burrs, and the reflective microstructure 3203 of the light guide plate 321 below can be clearly seen. As a result, the overall surface of the decorative component 200 of the electronic device is mottled and has a poor appearance.

[0030] Based on this, in the embodiments disclosed in this application, the decorative component 200 further includes a semi-permeable membrane 230, which can be disposed in at least a portion of the lens 220. When the light source 310 is in operation, light is emitted after passing through the light guide 320, the diffuser 330, and the semi-permeable membrane 230. The light transmittance of the semi-permeable membrane 230 is less than that of the lens 220. For example, the light transmittance of the lens 220 can be understood as 100%, while the light transmittance of the semi-permeable membrane 230 is less than 100%. Therefore, the light transmittance of the semi-permeable membrane 230 is low. At this time, the semi-permeable membrane 230 has a certain degree of haze. For example, the light transmittance of the semi-permeable membrane 230 can be 70%, while the haze can be 30%. Of course, the light transmittance of the semi-permeable membrane 230 in this application can also be other values, as long as it is less than the light transmittance of the lens 220.

[0031] Specifically, when the light source 310 is in operation, light passes through the light guide 320, the diffuser 330, and the semi-permeable membrane 230 before being emitted. At this time, the semi-permeable membrane 230 is illuminated, thus creating a light emission effect. When the light source 310 is not in operation, that is, when the light source 310 does not emit light and no light is emitted from the inside, the area of ​​the lens 220 where the semi-permeable membrane 230 is attached has a certain degree of haze when viewed from the outside. This provides a certain degree of shielding for the components below the lens 220, thereby preventing direct visibility of the structure below the lens 220.

[0032] In this scheme, when the light source 310 is not in operation, ambient light passes through the semi-permeable membrane 230 and is diffusely scattered or partially absorbed, resulting in a decrease in transparency. The diffuser 330 below the lens 220 is not easily seen, thus making the overall surface of the decorative component 200 of the electronic device uniform and improving its appearance. This is beneficial to improving the appearance performance of the electronic device.

[0033] In addition, the semi-permeable membrane 230 has a certain degree of haze, so the semi-permeable membrane 230 also has a certain diffusion effect, which is conducive to further improving the uniformity of light output.

[0034] In the above scheme, the light transmittance of the semi-permeable film 230 can be between 7% and 10%. At this time, the semi-permeable film 230 is close to black. Therefore, when the light source 310 is not in operation, the color of the area of ​​the lens 220 where the semi-permeable film 230 is attached is close to black. In one scheme, the light transmittance of the semi-permeable film 230 can be 8%.

[0035] Optionally, the semi-permeable membrane 230 can be made of semi-permeable ink, nano-coating, or other materials capable of achieving semi-transparency; this document does not impose any restrictions on its use. Additionally, the diffuser 330 can be made using a transparent substrate with internally premixed micro-scattering particles. The light guide 320 can be made of PMMA (Polymethylmethacrylate), PC (Polycarbonate), glass, or other materials; this document does not impose any restrictions on its use. The light source 310 can be an LED (Light Emitting Diode), high-pressure sodium lamp, metal halide lamp, or other structures; this document does not impose any restrictions on its use.

[0036] In another alternative, a first texture structure 340 may be provided on the diffuser 330. In this solution, when the light source 310 is lit, the first texture structure 340 on the diffuser 330 is illuminated, thus visually floating independently on the lens 220, thereby enriching the appearance layering and forming a novel and unique floating light-emitting effect, thereby further improving the appearance performance of the electronic device.

[0037] Optionally, the first texture structure 340 can be an independent film or film layer structure, and the first texture structure 340 can be attached to the side of the diffuser 330 facing the lens 220 or the side away from the lens 220.

[0038] In one embodiment, a first texture structure 340 can be formed on the diffuser 330 by a hot pressing process. For example, a three-dimensional texture such as micro-ridges, dotted textures, or wavy textures can be formed on the diffuser 330 by hot pressing.

[0039] Optionally, the thickness of the diffuser 330 can be 0.5 mm, or other thicknesses, which are not limited in this article.

[0040] In the above scheme, a light source 310 is provided in the second through hole 3201. The large-angle light from the light source 310 is likely to be directed directly to the diffuser 330 without passing through the light guide 320, which may lead to excessive brightness in the area opposite to the lens 220. Therefore, the area opposite to the lens 220 of the second through hole 3201 is prone to high-brightness spot damage.

[0041] Based on this, in an optional embodiment, the electronic device may further include a light-shielding film 350, which may be located on the side of the diffuser 330 facing the light guide 320, and the light-emitting light source 310 may be located on the side of the light-shielding film 350 away from the diffuser 330. The light-shielding film 350 may cover the second through hole 3201.

[0042] In this scheme, the light-shielding film 350 covers the second through hole 3201 of the light-emitting light source 310, thereby covering the light-emitting light source 310 to intercept the large-angle oblique direct stray light emitted from the light-emitting light source 310, thus preventing the stray light from bypassing the light guide 320 and directly irradiating the diffuser 330. Therefore, it effectively eliminates the defects of popping points and bright spots caused by excessive brightness in the area of ​​the lens 220 corresponding to the second through hole 3201, which is conducive to further improving the overall brightness uniformity of the emitted light.

[0043] The light-shielding film 350 in this application is located on the side of the light-emitting side of the light-emitting light source 310, that is, above the light-emitting light source 310. Therefore, the light-shielding film 350 does not block the light from the incident light guide 320.

[0044] In this application, the light-shielding film 350 can be made of materials such as black PET (Polyethylene terephthalate) or black PC, or other light-shielding materials, which are not limited herein.

[0045] In the above scheme, the light source 310 can be a ring-shaped light strip. In this case, the ring-shaped light strip is arranged at intervals along the circumference of the second through hole 3201.

[0046] In another embodiment, the light source 310 may include multiple light-emitting elements 311, each with its light-emitting surface facing the wall of the second through hole 3201, and the multiple light-emitting elements 311 are arranged at intervals along the circumference of the second through hole 3201. In this embodiment, the multiple light-emitting elements 311 achieve uniform circumferential light input to the second through hole 3201, resulting in more uniform light emission performance and higher brightness around the plane of the light guide 320. Furthermore, the separate arrangement of the multiple light-emitting elements 311 allows for more flexible positioning and simpler, more convenient position adjustment.

[0047] Optionally, the number of light-emitting elements 311 can be four, and the four light-emitting elements 311 are arranged symmetrically along the central axis of the first through hole 211. That is, the angle between any two adjacent light-emitting elements 311 is 90°.

[0048] In the above scheme, the light intensity between two adjacent light-emitting elements 311 is less than the light intensity of the light-emitting surface of each light-emitting element 311. Therefore, the brightness of the area on the light guide 320 opposite to the light-emitting surface of each light-emitting element 311 is greater than the brightness of the area on the light guide 320 opposite to the adjacent two light-emitting elements 311. This results in poor light uniformity of the hole wall of the second through hole 3201, which in turn leads to poor light uniformity of the output.

[0049] Based on this, in another optional embodiment, the electronic device may further include a reflective film 360. The reflective film 360, the light-shielding film 350, and the light-emitting element 311 are arranged along the first direction Z. The light-shielding film 350 may have a notch 351 in the area between two adjacent light-emitting elements 311. At least a portion of the reflective film 360 is disposed opposite to the notch 351. In this case, the area of ​​the light-emitting element 311 facing the light-shielding film 350 is a solid light-shielding surface to block the large-angle light from the light-emitting element 311. In the area between adjacent light-emitting elements 311, the light-shielding film 350 has a notch 351, thereby exposing the reflective film 360. The reflective film 360 can increase the light reflection efficiency between adjacent light-emitting elements 311, thereby increasing the light intensity in the area between adjacent light-emitting elements 311.

[0050] In this scheme, by opening a notch 351 in the light-shielding film 350, the reflective film 360 can be exposed, thereby improving the brightness of the area on the light guide 320 that is opposite to the two adjacent light-emitting elements 311. This ensures the uniformity of circumferential light entering the second through hole 3201, and thus improves the uniformity of light output.

[0051] In the above scheme, there can be multiple reflective films 360, and each reflective film 360 corresponds to a notch 351.

[0052] In another alternative embodiment, in the first direction Z, the orthographic projection of the light-shielding film 350 can lie within the orthographic projection of the reflective film 360. In this embodiment, the area of ​​the reflective film 360 is larger than the area of ​​the light-shielding film 350, thus allowing for only one reflective film 360, thereby simplifying the assembly process.

[0053] Optionally, the reflective film 360 can be a white film. Of course, the reflective film 360 can also be made of other materials with reflective properties, which is not limited in this article.

[0054] In another alternative embodiment, the electronic device may further include a reflector 370, which may be located between the decorative body 210 and the light guide 320. The reflector 370 may have a reflective surface, which may be located on the side of the reflector 370 facing the light guide 320. The reflector 370 may have a fifth through hole 371, which may be opposite to the first through hole 211. Here, the fifth through hole 371 is used to avoid obstructing the lens of the camera module 400.

[0055] In this scheme, the reflective surface can reflect the light emitted from the side of the light guide 320 away from the lens 220 back into the light guide 320, thereby improving the utilization efficiency of light and effectively increasing the brightness.

[0056] In an optional embodiment, the reflector 370 has a sixth through hole 372 spaced apart from the fifth through hole 371 along a direction perpendicular to the first direction Z. The sixth through hole 372 is disposed opposite to the second through hole 3201. Here, the sixth channel is opened in the area opposite to the second through hole 3201 of the light guide 320. Therefore, the second through hole 3201 helps to reduce the light utilization rate at the light-incident position of the light guide 320, thereby reducing the brightness at the light-incident position of the light guide 320.

[0057] Optionally, when the light source 310 is a ring-shaped light strip, the circumferential light emission of the ring-shaped light strip is relatively uniform. Therefore, the sixth through hole 372 and the second through hole 3201 can be coaxially arranged, and the aperture of the sixth through hole 372 is larger than the aperture of the second through hole 3201. In this case, the brightness at the light-incident position of the light guide 320 can be reduced.

[0058] When the light source 310 includes multiple light-emitting elements 311, enlarging the size of the sixth through-hole 372 would affect the overall light uniformity of the light guide 320. Therefore, in another embodiment, along the circumferential direction of the sixth through-hole 372, the distance between each light-emitting element 311 and the wall of the sixth through-hole 372 decreases from its center towards its two edges. Here, the center can be understood as the center of the light-emitting surface of the light-emitting element 311, or the central optical axis of the light-emitting element 311. Alternatively, it can be understood that the area of ​​the sidewall 3721 of the sixth through-hole 372 opposite to each light-emitting element 311 forms a through-hole along the first direction Z, and the width of the through-hole gradually decreases in the direction in which the light-emitting element 311 points towards the through-hole.

[0059] In this design, the light intensity distribution curve of the light-emitting element 311 presents a symmetrical figure with the normal direction as the axis of symmetry. The light intensity is maximum in the normal direction, and gradually decreases as the angle deviates from the normal direction. The curve shape resembles a "flattened circle". At this time, the contour structure of the notch opposite to the light-emitting element 311 is set as a trumpet shape with a large opening width and a small bottom wall width, which can better match the light intensity distribution curve of the light-emitting element 311, thereby further improving the light-incident uniformity of the light guide 320, and thus further improving the light emission uniformity.

[0060] Furthermore, the wall of the sixth through hole 372 may include multiple sidewalls 3721 connected end to end, with any two adjacent sidewalls 3721 intersecting to form a vertex 3722. Each light-emitting element 311 corresponds to a vertex 3722, and each vertex 3722 is positioned opposite to the central region of its corresponding light-emitting element 311. This can be understood as the outline of the sixth through hole 372 being a polygonal structure, such as a quadrilateral, pentagon, or hexagon, with each light-emitting element 311 situated between two adjacent sides of the polygonal structure, and the center or central optical axis of the light-emitting element 311 opposite to the vertex 3722 formed by the two sides. In this case, there is a certain included angle between the two adjacent sides, thus enabling the distance between each light-emitting element 311 and the wall of the sixth through hole 372 to decrease from its center towards its two edges.

[0061] In this design, the sixth through hole 372 has a polygonal structure, which is simpler and more regular, making it easier to manufacture.

[0062] In the above scheme, the wall of the sixth through hole 372 can be curved or flat, and the apex 3722 formed between two adjacent side walls 3721 can also be a rounded corner.

[0063] In another optional embodiment, the first direction Z, the second direction X, and the third direction Y are mutually perpendicular, and the plane containing the second direction X and the third direction Y is the plane containing the light guide 320 mentioned above. In both the second direction X and the third direction Y, the distribution density of the reflective microstructures 3203 is positively correlated with the distance between the light-emitting sources 310. In this case, the density distribution of the reflective microstructures 3203 in both the lateral and longitudinal directions within the plane is proportional to the distance between the light-emitting sources 310. For example, the second through-hole 3201 is located at the lower left of the light guide 320, and the arrangement density of the reflective microstructures 3203 increases from the lower left corner downwards to the right. Simultaneously, since the second through-hole 3201 is located at the bottom, the sealing of the reflective microstructures 3203 increases from bottom to top. Therefore, the position with the highest density of the reflective microstructures 3203 is the upper right corner of the light guide 320, which is furthest from the light-emitting source 310.

[0064] In this solution, the bidirectional gradient distribution of the reflective microstructure 3203 enables ultra-dense arrangement in the area blocked by the camera module 400, thus maximizing the light output effect and effectively improving the uniformity of light output from the light guide 320 and the brightness of the blocked area.

[0065] In another embodiment, when the light source 310 includes multiple light-emitting elements 311, the distribution density of reflective microstructures 3203 in the region directly opposite the light-emitting surface of the light-emitting element 311 and the light guide 320 is greater than the distribution density of reflective microstructures 3203 in the region of the light guide 320 corresponding to the position between two adjacent light-emitting elements 311. Since the light intensity at the position between two adjacent light-emitting elements 311 is less than the intensity of the light-emitting surface of the light-emitting element 311, reducing the distribution density of reflective microstructures 3203 in the region directly opposite the light-emitting surface of the light-emitting element 311 is beneficial to further improve the light emission uniformity of the light guide 320.

[0066] Optionally, the minimum spacing between the reflective microstructures 3203 of the phase can be 0.04 mm. Of course, other values ​​are also possible, and this paper does not impose any restrictions on them.

[0067] In the above embodiments, the reflective microstructure 3203 can be a convex point, a concave point, or other structures, which are not limited herein.

[0068] In one embodiment, the light guide 320 may include a light guide plate 321 and a light guide film 322, with the lens 220, diffuser 330, light guide film 322, and light guide plate 321 stacked sequentially. The light guide plate 321 may have a first sub-hole 3211, and the light guide film 322 may have a second sub-hole 3221. The first sub-hole 3211 and the second sub-hole 3221 may be arranged opposite to each other, forming the aforementioned second through-hole 3201. The light-emitting side of the light source 310 may be arranged opposite to the walls of both the first sub-hole 3211 and the second sub-hole 3221. The light guide plate 321 may also have a fifth sub-hole 3213, and the light guide film 322 may also have a sixth sub-hole 3223, forming the aforementioned third through-hole 3202.

[0069] The reflective microstructure 3203 may include a first reflective microstructure 3203a and a second reflective microstructure 3203b. The light guide plate 321 may be provided with the first reflective microstructure 3203a, which may be disposed on the side surface of the light guide plate 321 facing the light guide film 322 and / or the side surface facing away from the reflective film 360. The light guide film 322 may be provided with the second reflective microstructure 3203b, which may be disposed on the side surface of the light guide film 322 facing the diffuser 330 and / or the side surface facing away from the diffuser 330. In a direction perpendicular to the first direction Z, the distribution density of both the first reflective microstructure 3203a and the second reflective microstructure 3203b is positively correlated with the distance between the light source 310.

[0070] In this design, the light guide plate 321, being a rigid plate structure, is relatively thick. Therefore, the light guide plate 321 is mainly responsible for the transmission and initial distribution of light, achieving a large-area light guiding effect. The light guide film 322, being a thin film structure, is relatively thin. Therefore, the light guide film 322 is responsible for supplementing light energy and adjusting the light angle. The combination of the two allows for better optical performance while maintaining a lightweight structure.

[0071] Furthermore, the double-layer light guide 320 design extends the light path transmission distance, thereby facilitating a wider lateral light emission coverage area and achieving a larger area of ​​light emission. Simultaneously, the first reflective microstructure 3203a on the light guide plate 321 can regulate the large-path transmission of light within the thicker plate, while the second reflective microstructure 3203b on the light guide film 322 finely adjusts the light angle closer to the light-emitting surface. This double-layer light guide 320 design further enhances light emission uniformity, thus further preventing "near-bright, far-dark" light spots.

[0072] Optionally, the light guide plate 321 can be made of PMMA material with a thickness of 0.45mm; the light guide film 322 can be made of PC material with a thickness of 0.125mm. The diffuser 330 can have a thickness of 0.5mm. Of course, the materials and thicknesses of the light guide plate 321, the light guide film 322, and the diffuser 330 are not limited to those listed in this application, and can also be made of other materials and have other thicknesses, which are not limited herein.

[0073] Furthermore, the first direction Z, the second direction X, and the third direction Y are all perpendicular to each other. In the second direction X and the third direction Y, the distribution density of the first reflective microstructure 3203a and the second reflective microstructure 3203b are both positively correlated with the distance between the light source 310.

[0074] Taking the first reflective microstructure 3203a as an example, the density distribution of the first reflective microstructure 3203a in both the lateral and longitudinal directions within the plane is proportional to the distance between the light-emitting sources 310. For example, as... Figure 6 As shown, the first sub-hole 3211 is located at the lower left of the light guide plate 321, and the density of the first reflective microstructure 3203a increases from the lower left corner to the right. Simultaneously, since the first sub-hole 3211 is located at the bottom, the sealing of the first reflective microstructure 3203a increases from bottom to top. Therefore, the position with the highest density of the first reflective microstructure 3203a is the upper right corner of the light guide plate 321, which is furthest from the light source. Similarly, as... Figure 7As shown, the second sub-hole is located at the lower left of the light guide film 322, and the density of the second reflective microstructure 3203 increases from the lower left corner to the right. Simultaneously, since the second sub-hole 3221 is located at the bottom, the sealing of the second reflective microstructure 3203b increases from bottom to top. Therefore, the position with the highest density of the second reflective microstructure 3203 is the upper right corner of the light guide film 322, which is furthest from the light source.

[0075] In this solution, through the bidirectional gradient distribution of the first reflective microstructure 3203a and the second reflective microstructure 3203b, an ultra-dense arrangement can be further achieved in the area blocked by the camera module 400, thus maximizing the light output effect and effectively improving the overall uniformity of light output from the light guide 320 and the brightness of the blocked position.

[0076] In the above scheme, the reflective film 360 and the light-shielding film 350 can be located between the diffuser 330 and the light guide film 322, while the reflective element 370 can be located between the light guide plate 321 and the decorative body 210.

[0077] In another alternative embodiment, the lens 220 may also have a second textured structure, which may overlap with the semi-permeable film 230. In this embodiment, when the light source 310 is lit, the second textured structure is illuminated, thus appearing to float independently on the lens 220, thereby enriching the appearance and creating a novel and unique floating light-emitting effect, which further enhances the appearance performance of the electronic device.

[0078] In the above embodiment, the area of ​​the semi-permeable membrane 230 can be equal to the area of ​​the lens 220, in which case the semi-permeable membrane 230 completely covers the lens 220. This can be understood as the area of ​​the lens 220 opposite to the first through-hole 211 also being covered by the semi-permeable membrane 230. At this time, when the light source 310 is not working, the lens 220 exhibits a certain degree of haze, resulting in a uniform overall appearance. When the light source 310 is working, the lens 220 emits light in all areas except for the area opposite to the first through-hole 211 and the second through-hole 3201.

[0079] In another alternative embodiment, such as Figure 12 As shown, the lens 220 may include a first region 221 and a second region 222. The second region 222 may be arranged around the first region 221, and the first through hole 211 is arranged opposite to the first region 221. A semi-permeable film 230 may be attached to at least a portion of the second region 222. In this solution, the semi-permeable film 230 is not attached to the area opposite the lens of the camera module 400, so it will not affect the shooting performance of the camera module 400. Therefore, the semi-permeable film 230 is attached to the outer ring of the lens 220, which ensures that the decorative component 200 can achieve a large-area light emission effect and also ensures the shooting quality of the camera module 400.

[0080] Optionally, the semi-permeable membrane 230 can fully cover the second area 222.

[0081] In another alternative embodiment, such as Figure 13 As shown, the second region 222 may include a first sub-region 2221 and a second sub-region 2222. The first sub-region 2221 surrounds the first region 221, and the second sub-region 2222 surrounds the first sub-region 2221. In this case, the first sub-region 2221 and the first region 221 together constitute the inner ring of the lens 220, while the second sub-region 2222 is located at the edge of the lens 220, thus forming the outer ring of the lens 220. A semi-permeable film 230 can be attached to the second sub-region 2222. The first sub-region 2221 can be a light-shielding area. In this case, the first sub-region 2221 is not transparent, so the first sub-region 2221 can be provided with a light-shielding structure. For example, the first sub-region 2221 may have a black ink layer. Of course, it can also be a light-shielding structure made of other materials, which is not limited in this article. The second through hole 3201 can be disposed opposite to the first sub-region 2221.

[0082] In this design, the edge of the lens 220 forms a complete annular light-emitting ring. Therefore, regardless of whether the light-emitting source 310 emits light, the non-light-emitting area formed by the second through hole 3201 on the light guide 320 will be blocked by the first sub-region 2221 and will not be seen by the user. This further reduces the abruptness and improves the uniformity of the electronic device's appearance.

[0083] In the above scheme, the color of the first sub-region 2221 can be similar to or the same as the color of the second sub-region 2222. Therefore, a light-shielding ink layer can be applied to the first sub-region 2221, and a semi-transparent ink layer can be applied to the second sub-region 2222.

[0084] In another optional embodiment, the electronic device may further include a fill light module 500, which may be disposed on the side of the lens 220 facing the decorative body 210. The fill light module 500 may be mounted on the decorative body, or it may be mounted inside the housing 100. The decorative body 210 may also have a seventh through hole 212, the light guide 320 may also have an eighth through hole 3204, and the diffuser 330 may also have a ninth through hole 332. The fill light module 500 may be positioned opposite to the seventh through hole 212, the eighth through hole 3204, and the ninth through hole 332. The seventh through hole 212, the eighth through hole 3204, and the ninth through hole 332 are all used to avoid obstructing the fill light module 500.

[0085] In this solution, the decorative component 200 integrates a fill light module 500, which is conducive to further improving the integrated design of electronic devices and optimizing the internal space layout of electronic devices.

[0086] In the above scheme, the supplementary lighting module 500 can be located on the lens 220 where the semi-permeable film 230 is provided, or it can be located on an area of ​​the lens 220 where the semi-permeable film 230 is not provided. This article does not impose any restrictions on this.

[0087] In an optional embodiment, the second region 222 further includes a third sub-region 2223, with the first sub-region 2221 surrounding the third sub-region 2223, and the third sub-region 2223 positioned opposite to the supplementary lighting module 500. In this case, a semi-permeable film 230 may also be attached to the third sub-region 2223. In this solution, the semi-permeable film 230 can shield the light-emitting area corresponding to the supplementary lighting module 500, making it difficult to observe the light-emitting position on the lens 220 corresponding to the supplementary lighting module 500 when the supplementary lighting module 500 is not emitting light, thus further improving the appearance consistency of the electronic device.

[0088] In the above scheme, when the light guide 320 includes a light guide plate 321 and a light guide film 322, the light guide plate 321 may further include a third sub-hole 3212, and the light guide film 322 may further include a fourth sub-hole 3222. The third sub-hole 3212 and the fourth sub-hole 3222 form the aforementioned eighth through hole 3204. Furthermore, the aforementioned reflector 370 may also have a tenth through hole 373, which is used to avoid obstructing the supplementary lighting module 500.

[0089] In one alternative, the light source 310 described above can be entirely located within the receiving cavity 201.

[0090] In another embodiment, the decorative body 210 may have an eleventh through hole 214 that is opposite to and connected to the second through hole 3201, and the light source 310 can extend into the second through hole 3201 through the eleventh through hole 214. In this embodiment, the eleventh through hole 214 facilitates the circuit connection between the light source 310 and the circuit devices inside the housing 100, thereby optimizing the layout structure of the electronic device.

[0091] In the electronic device disclosed in this application, the decorative component 200 may further include an annular frame 240, which may surround the lens 220 and the annular edge may be connected to the decorative component body 210. In this solution, the annular frame 240 surrounds the lens 220, which can limit the lens 220 in all directions, effectively preventing the lens 220 from shifting or falling off during use, while evenly dispersing external impacts and reducing the probability of the lens 220 cracking or breaking. In addition, the annular frame 240 covers the assembly gap between the lens 220 and the decorative component body 210 and the side processing defects of the lens 220, thereby improving the product's appearance and allowing for independent appearance processing, enriching the product's design. Furthermore, the annular frame 240 wraps around the outer edge of the lens 220, which can prevent the edge of the lens 220 from being scratched by friction, while also preventing dust and moisture from entering the interior from the side gaps, thus providing dust and moisture protection.

[0092] In the above scheme, the annular frame 240 can be made of PC material, but other materials can also be used, which is not limited here. The color of the annular frame 240 can be consistent with the color of the diffuser 330 and / or the semi-permeable film 230, thereby improving the poor appearance consistency caused by the color layering of the decorative component 200.

[0093] Furthermore, the annular frame 240 can be integrally formed with the lens 220. The annular frame 240 has a first step structure 241 on the side facing the decorative body 210, and the decorative body 210 has a second step structure 213 on the side facing the annular frame 240. The first step structure 241 and the second step structure 213 are interlocked.

[0094] In this design, the annular frame 240 and the lens 220 are integrally molded, eliminating assembly gaps between the lens 220 and the frame, improving dust and water resistance, and eliminating the lens 220 assembly process, simplifying the production process and preventing loosening and noise caused by relative sliding between the lens 220 and the frame. Furthermore, the annular frame 240 and the decorative component body 210 are interlocked through a first stepped structure 241 and a second stepped structure 213, achieving multi-directional positioning and preventing displacement or detachment after assembly. The stepped overlap increases the contact area and enhances the connection strength. Simultaneously, the stepped arrangement forms a labyrinthine sealed channel, further preventing dust and moisture from entering the interior; the stepped structure also disperses assembly clamping force, preventing the integrally molded lens 220 from breaking under pressure, thus improving product structural reliability.

[0095] In the above scheme, the annular frame 240 and the lens 220 can be integrally molded using two-color injection molding or nano-injection molding. The specific number of stepped surfaces of the first stepped structure 241 and the second stepped structure 213 can be flexibly set according to the actual working conditions, and this article does not impose any restrictions.

[0096] In this application, the decorative body 210 may have a first protrusion 215 and a second protrusion 216 on the side facing the lens 220. A first through hole 211 passes through the first protrusion 215, and the side of the first protrusion 215 facing away from the decorative body 210 abuts against the lens 220. A seventh through hole 212 passes through the second protrusion 216, and the side of the second protrusion 216 facing away from the decorative body 210 abuts against the lens 220.

[0097] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices (such as smartwatches), video game consoles, etc. This application does not limit the specific types of electronic devices.

[0098] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
