[0002] This application claims priority to Chinese Patent Application No. 202410962950.6, filed on July 18, 2024, entitled "Lens Assembly and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic equipment technology, specifically relating to a lens assembly and an electronic device. Background Technology

[0004] Electronic devices can provide lighting effects through light-emitting components, such as a breathing light mode that provides a gradual change in brightness or color, similar to breathing. As the electronic product with the highest human-computer interaction rate, mobile phones offer a wider range of applications for their light-emitting components, providing users with personalized and differentiated user experiences.

[0005] In related technologies, the light-emitting components on the mobile phone battery cover are mostly light strips, and the light strips are mostly arranged on the lens module to form a light display area on the lens module.

[0006] However, light strips require a large installation space and heat dissipation space, while the layout space of the lens module area is relatively small. Without changing the size of the lens module, electronic devices face a bottleneck in space layout, and there are technical problems that the light-emitting components cannot be reasonably arranged. Summary of the Invention

[0007] This application aims to provide an electronic device that at least solves the technical problem of spatial layout bottlenecks and the inability to rationally arrange light-emitting components.

[0008] In a first aspect, embodiments of this application propose a lens assembly, which includes: a bracket; a decorative ring assembly disposed on the bracket; a cover plate connected to the bracket, the decorative ring assembly located between the cover plate and the bracket, the cover plate including a first light-transmitting area disposed opposite to the decorative ring assembly; a light-emitting component disposed on the bracket; and a light-guiding component disposed adjacent to the first light-transmitting area, the light-guiding component being connected to the light-emitting component and guiding the light from the light-emitting component to the first light-transmitting area.

[0009] Secondly, embodiments of this application provide an electronic device, which includes: a housing; a lens assembly as described in the first aspect embodiment, wherein the bracket is connected to the housing.

[0010] This application incorporates a light guide component, enabling the light-emitting component to direct emitted light to a first light-transmitting area on the cover plate. During its transmission to this area, the light indirectly illuminates a decorative ring component located below it, thus providing a lighting effect through the light reaching the first light-transmitting area and the indirectly illuminated decorative ring component. Compared to directly arranging a ring-shaped light strip below the cover plate, the light-emitting component illuminating the decorative ring component using the light guide component can be made smaller. Specifically, the space inside the decorative ring can be utilized more effectively for assembly, overcoming the spatial layout bottleneck within the lens assembly. Furthermore, the decorative ring component itself provides positioning and support for the cover plate; its placement below the first light-transmitting area prevents obstruction by other structures and eliminates the need to sacrifice size for the light guide component and light-emitting component, thereby improving the lighting display effect.

[0011] Therefore, this application solves the technical problem of spatial layout bottleneck and inability to reasonably arrange light-emitting components by setting light-emitting components and light-guiding components to illuminate the decorative ring component below the first light-transmitting area.

[0035] The lens assembly and electronic device according to embodiments of this application are described below with reference to Figures 1 to 17.

[0036] As shown in Figures 1, 2, and 3, a lens assembly 100 according to some embodiments of this application includes: a bracket 110; a decorative ring assembly 120 disposed on the bracket 110; a cover plate 130 connected to the bracket 110, the decorative ring assembly 120 located between the cover plate 130 and the bracket 110, the cover plate 130 including a first light-transmitting area 132 disposed opposite to the decorative ring assembly 120; a light-emitting component disposed on the bracket; and a light-guiding component disposed adjacent to the first light-transmitting area, the light-guiding component being connected to the light-emitting component and guiding the light from the light-emitting component to the first light-transmitting area.

[0037] In this embodiment, a lens assembly 100 is defined, which can acquire image information on an electronic device 200 to meet the user's photography needs, image information scanning needs, or video call needs through the acquired image information.

[0038] The lens assembly 100 includes a bracket 110, a decorative ring assembly 120, and a cover plate 130. The bracket 110 is the main frame structure of the lens assembly 100 and is used to position and support other structures on the lens assembly 100.

[0039] The decorative ring assembly 120 is mounted on the bracket 110. After assembly, the decorative ring assembly 120 can differentiate the appearance of the bracket 110 by its material. For example, the bracket 110 can be made of a low-density plastic with good insulation, while the decorative ring assembly 120 can be made of an alloy with a superior appearance and texture. Furthermore, the decorative ring assembly 120 can also conceal the bracket 110, preventing the exposed bracket 110 from appearing abrupt after assembly.

[0040] The cover plate 130 is fitted onto the bracket 110, and the decorative ring assembly 120 provides radial positioning (arrow b in Figure 3 indicates the radial direction of the decorative ring assembly 120) of the cover plate 130 around its periphery. The cover plate 130 has a light-transmitting area and a light-shielding area, while the bracket 110 has a clearance area, which is positioned opposite to the light-transmitting area. The image acquisition device can capture external light through the clearance area and the light-transmitting area to achieve image acquisition. The light-shielding area can also shield the bracket 110, thus avoiding the abruptness of the exposed bracket 110. At the same time, the cover plate 130 can protect the inner structure from external impacts and contaminant corrosion, thereby protecting the inner structure.

[0041] Based on this, the lens assembly 100 is provided with a light guide component 140 and a light-emitting component 150. The light guide component 140 and the light-emitting component 150 are mounted on the side of the bracket 110 facing the cover plate 130, and the light guide component 140 and the light-emitting component 150 are arranged opposite to the light-shielding area. After the assembly is completed, the light guide component 140 and the light-emitting component 150 cannot be seen from the cover plate 130. At the same time, the light guide component 140 is arranged adjacent to the first light-transmitting area 132 to guide the light to the adjacent first light-transmitting area 132.

[0042] Specifically, the light-transmitting area includes a first light-transmitting area 132, which is positioned opposite to the decorative ring assembly 120. After assembly, the decorative ring assembly 120 can be observed from the outside of the cover plate 130 through the first light-transmitting area 132. When the light-emitting component 150 is turned on, the light generated by the light-emitting component 150 can be guided to the first light-transmitting area 132 through the light guide component 140, thereby illuminating the first light-transmitting area 132. During the transmission of light to the first light-transmitting area 132, the light can also illuminate the decorative ring assembly 120 below the first light-transmitting area 132, so that the decorative ring assembly 120 exposed inside the first light-transmitting area 132 presents a lighting effect. For example, by controlling the gradual brightness of the light-emitting component 150, a light effect similar to a breathing light can be presented on the decorative ring assembly 120.

[0043] This application, by setting a light guide component 140, enables the light-emitting component 150 to guide the emitted light to the first light-transmitting area 132 on the cover plate 130. During the transmission of light to the first light-transmitting area 132, the light can also indirectly illuminate the decorative ring component 120 below the first light-transmitting area 132, thereby providing a lighting effect through the light transmitted to the first light-transmitting area 132 and the indirectly illuminated decorative ring component 120. Compared to the solution of directly arranging a ring-shaped light strip below the cover plate 130, the size of the light-emitting component 150 illuminating the decorative ring component 120 using the light guide component 140 can be made smaller. Specifically, the space inside the decorative ring can be reasonably utilized for assembly, thus overcoming the spatial layout bottleneck inside the lens assembly 100. Simultaneously, the decorative ring component 120 itself serves to position and support the cover plate 130. The decorative ring component 120, located below the first light-transmitting area 132, will not be obstructed by other structures, and there is no need to sacrifice size for assembling the light guide component 140 and the light-emitting component 150, thereby improving the lighting display effect.

[0044] It can be seen that by setting the light-emitting component 150 and the light-guiding component 140 to illuminate the decorative ring component 120 below the first light-transmitting area 132, this application solves the technical problem of spatial layout bottleneck and inability to reasonably arrange the light-emitting components in the related technology.

[0045] On the other hand, compared with large-area light strips, the light-emitting component 150 that provides indirect lighting through the light guide component 140 generates less heat during operation, and the reserved heat dissipation space can be appropriately reduced, which is conducive to breaking through the spatial layout bottleneck of the lens component 100 and can reduce the probability of overheating failure of the light-emitting component 150.

[0046] On the other hand, reducing the heat dissipation space can also provide convenient conditions for the miniaturization and lightweight design of the lens assembly 100, thereby achieving the technical effect of improving the practicality and structural compactness of the lens assembly 100.

[0047] As shown in Figures 4, 5 and 6, in some embodiments, optionally, the light guide component 140 is disposed inside the decorative ring assembly 120; the decorative ring assembly 120 has a light-transmitting groove on the side near the light guide component 140, and the orthographic projection of the light-transmitting groove on the cover plate 130 at least partially overlaps with the first light-transmitting area 132.

[0048] In this embodiment, the light guide component 140 and the light-emitting component 150 are disposed inside the decorative ring. By disposing of the light guide component 140 and the light-emitting component 150 inside the decorative ring assembly 120, the light guide component 140 and the light-emitting component 150 can be shielded by the decorative ring assembly 120 and the cover plate 130, and the assembly space inside the decorative ring can be reasonably utilized.

[0049] Based on this, a light-transmitting groove 1244 is provided on the side of the decorative ring assembly 120 near the light guide component 140, so that the light emitted by the light guide component 140 can enter the adjacent light-transmitting groove 1244.

[0050] Furthermore, a projection is made onto the cover plate 130 from the light-transmitting groove 1244 to obtain a projection area, wherein the projection area on the cover plate 130 at least partially overlaps with the first light-transmitting area 132, thereby ensuring that the light in the light-transmitting groove 1244 can be directed toward the first light-transmitting area 132, so that the first light-transmitting area 132 exhibits a lighting effect.

[0051] As shown in Figures 4, 5 and 6, in some embodiments, optionally, the bottom of the light-transmitting groove has an inclined surface; the inclined surface has reflective patterns.

[0052] In this embodiment, the decorative ring assembly 120 has an inclined surface 1242 on the side facing the cover plate 130. The inclined surface 1242 is opposite to the first light-transmitting area 132 on the cover plate 130, allowing the user to see the inclined surface 1242 below through the first light-transmitting area 132. The top surface of the decorative ring assembly 120 is in contact with the bottom surface of the cover plate 130, and the inclined surface 1242 is inclined away from the cover plate 130 relative to the top surface of the decorative ring assembly 120. After assembly, the inclined surface 1242 and the bottom surface of the cover plate 130 together form a light-transmitting groove 1244. In the radial direction of the decorative ring assembly 120, the light-transmitting groove 1244 is opposite to the light-guiding component 140 inside the decorative ring, allowing light emitted from the light-guiding component 140 to be transmitted into the light-transmitting groove 1244.

[0053] During operation, the light-emitting component 156 transmits light to the decorative ring assembly 120 through the light guide component 140. After the light enters the light-transmitting groove 1244, it is reflected by the inclined surface 1242 and transmitted to the first light-transmitting area 132 at the top of the inclined surface 1242. This allows the user to observe the inclined surface 1242 illuminated by the light guide component 140 through the first light-transmitting area 132, thus displaying the specified lighting effect in the first light-transmitting area 132. Therefore, the light-transmitting groove 1244 formed by the inclined surface 1242 can optimize the light path, enabling the lighting component and the light guide component 140 to work together with the inclined surface 1242 to provide a better lighting effect in the first light-transmitting area 132.

[0054] Specifically, the inclined surface 1242 is an inclined surface, and the inclination angle of the inclined surface 1242 relative to the cover plate 130 is greater than or equal to 15° and less than or equal to 60°. Specifically, the inclination angle can be selected as 30° or 45°.

[0055] Based on this, the inclined surface 1242 can be processed with reflective patterns and reflective layers through processes such as electroplating. When the light guide component 140 illuminates the inclined surface 1242, the reflective layer makes it easier for the user to observe the illuminated inclined surface 1242, and the reflective patterns allow the user to observe high-brightness patterns on the inclined surface 1242, thereby displaying a light-emitting pattern corresponding to the shape of the reflective patterns in the first light-transmitting area 132, thereby achieving the technical effect of optimizing the lighting effect and improving the user experience.

[0056] As shown in Figures 2, 3, 5 and 6, in some embodiments, optionally, the decorative ring assembly 120 includes: an outer ring 122 connected to the bracket 110 and the cover plate 130, the outer ring 122 partially surrounding the periphery of the cover plate 130; and an inner ring 124 connected to the outer ring 122.

[0057] In this embodiment, the decorative ring assembly 120 includes an inner ring 124 and an outer ring 122. The inner ring 124 is fitted inside the outer ring 122 to achieve axial positioning (arrow a in Figure 2 shows the axial direction of the decorative ring assembly 120). The outer ring 122 is provided with a mounting position, and the cover plate 130 is fastened to the mounting position. After the cover plate 130 is assembled, the edge of the outer ring 122 wraps around the cover plate 130, thereby providing shielding protection for the cover plate 130 on its periphery. At the same time, the cover plate 130 shields the inner ring 124 below, which on the one hand provides protection for the inner ring 124, and on the other hand can cooperate with the outer ring 122 to clamp and position the inner ring 124, thereby achieving radial positioning of the inner ring 124.

[0058] The first light-transmitting area 132 is annular on the cover plate 130, and is opposite to the inner ring 124 of the ring. The user can observe the inner ring 124 through the first light-transmitting area 132. An inclined surface 1242 is machined on the inner ring 124. The cover plate 130 and the inner ring 124, which are fastened together, form a light-transmitting groove 1244 surrounding the light guide component 140.

[0059] By setting a separate inner ring 124 and outer ring 122, the inner ring 124 and outer ring 122 can be made of different materials, so that the inner ring 124 and outer ring 122 have different properties.

[0060] Specifically, the outer ring 122 can be made of metal. Metal has the advantages of high structural strength, good gloss and texture. On the one hand, the metal outer ring 122 can effectively resist impact around the inner ring 124 and the cover plate 130, improving the protective effect of the outer ring 122 on the inner cover plate 130 and the inner ring 124. On the other hand, the metal outer ring 122 can form a ring with metallic luster and metallic texture around the cover plate 130, thereby optimizing the appearance of the lens assembly 100 and improving the user experience.

[0061] Based on this, the inner ring 124 can be made of plastic. Compared with metal, plastic has the advantage of low density, and choosing plastic to make the inner ring 124 can facilitate the lightweight design of the lens assembly 100. At the same time, plastic is suitable for injection molding, which can reduce the process complexity and cost of the inner ring 124.

[0062] Specifically, the inclined surface 1242 on the inner ring 124 can be processed with reflective patterns and reflective layers through processes such as electroplating. When the light guide component 140 illuminates the inclined surface 1242, the reflective layer makes it easier for the user to observe the illuminated inclined surface 1242, and the reflective patterns allow the user to observe high-brightness patterns on the inclined surface 1242, thereby displaying a light-emitting pattern corresponding to the shape of the reflective patterns in the first light-transmitting area 132, thereby achieving the technical effect of optimizing the lighting effect and improving the user experience.

[0063] Specifically, the inner ring 124 and the outer ring 122 are connected by a fifth adhesive component 129. The outer ring 122, which surrounds the inner ring 124, provides radial positioning for the inner ring 124, and the fifth adhesive component 129 provides axial positioning for the inner ring 124.

[0064] As shown in Figures 5 and 6, in some embodiments, optionally, the bracket 110 includes: a light-shielding bracket 112 connected to the cover plate 130; and a light-transmitting bracket 114 connected to the light-shielding bracket 112, the light-transmitting bracket 114 being located between the light-shielding bracket 112 and the decorative ring assembly 120, the light-transmitting bracket 114 including a mounting groove 1142, a light guide component 140 disposed within the mounting groove 1142, and the cover plate 130 covering the mounting groove 1142.

[0065] In this embodiment, the bracket 110 includes a light-shielding bracket 112 and a light-transmitting bracket 114, which are nested together, with the light-transmitting bracket 114 fitted over the outside of the light-shielding bracket 112. After assembly, the light-transmitting bracket 114 is located between the light-shielding bracket 112 and the decorative ring assembly 120 in the radial direction of the decorative ring assembly 120.

[0066] Based on this, the tops of the light-shielding bracket 112 and the light-transmitting bracket 114 are connected to the cover plate 130 via the second adhesive component 138. The light-transmitting bracket 114 has a recessed mounting groove 1142 on the side facing the cover plate 130. The shape of the mounting groove 1142 is adapted to the shape of the light guide component 140. After assembly, the light guide component 140 is embedded in the mounting groove 1142. By setting the mounting groove 1142, the light guide component 140 is positioned to ensure that it can be installed in the predetermined installation position. On the other hand, by setting the mounting groove 1142, the light guide component 140 can make reasonable use of the space inside the bracket 110, avoiding the light guide component 140 from encroaching on the space between the bracket 110 and the decorative ring assembly 120, and avoiding the light guide component 140 from increasing the size of the lens assembly 100. This achieves the technical effect of improving the structural compactness of the lens assembly 100 and providing convenient conditions for the miniaturization design of the lens assembly 100.

[0067] In this system, light can be transmitted through the light-transmitting bracket 114, but cannot be transmitted through the light-shielding bracket 112. During operation, a portion of the light emitted by the light guide component 140 is transmitted through the light-transmitting bracket 114 towards the light-transmitting groove 1244, while the other portion is reflected and its transmission direction is changed after contacting the inner light-shielding bracket 112. Therefore, by setting the light-shielding bracket 112 inside the light-transmitting bracket 114, light can be prevented from transmitting to the central area away from the light-transmitting groove 1244, thereby increasing the amount of light incident on the light-transmitting groove 1244 and thus increasing the brightness of the light displayed in the first light-transmitting area 132. This achieves the technical effects of optimizing the light path, optimizing the lighting effect, and reducing the energy consumption of the light-emitting component 150.

[0068] Specifically, the material of the light-transmitting bracket 114 includes a light-diffusing material, which can disperse the light incident into the interior of the light-transmitting bracket 114 to improve the uniformity of illumination on the inclined surface 1242 and avoid obvious bright and dark areas on the inclined surface 1242, thereby achieving the technical effect of improving the uniformity of light emission.

[0069] As shown in Figures 6 and 7, in some embodiments, the lens assembly 100 may optionally include:

[0070] A light-shielding component 160 is disposed in the mounting groove 1142, and the light-shielding component 160 is located on the side of the light guide component 140 facing away from the cover plate 130.

[0071] A light-shielding layer 162 is disposed between the cover plate 130 and the light-transmitting bracket 114, and the light-shielding layer 162 avoids the first light-transmitting area 132.

[0072] In this technical solution, a light-shielding component 160 is provided in the mounting groove 1142. After assembly, the light-shielding component 160 is located on the side of the light guide component 140 facing away from the cover plate 130. The light-shielding component 160 can block the light transmitted to the area facing away from the cover plate 130.

[0073] Based on this, a light-shielding layer 162 is provided between the cover plate 130 and the light-transmitting bracket 114. The light-shielding layer 162 can be disposed on the surface of the cover plate 130 facing the light-transmitting bracket 114, or it can be disposed on the surface of the second adhesive component 138. The light-shielding layer 162 can block light from being transmitted to the cover plate 130. Specifically, the light-shielding layer 162 avoids the first light-transmitting area 132 and the second light-transmitting area 134 to avoid affecting the lighting display effect and the image information acquisition effect.

[0074] Therefore, the light-shielding component 160 and the light-shielding layer 162 can block light on the upper and lower sides of the light guide component 140. Combined with the light-shielding bracket 112 in the aforementioned embodiment, which blocks light transmission inside the light guide bracket 110, the light transmitted to the light-transmitting bracket 114 can be concentrated, allowing the light to be directed towards the area where the light-transmitting groove 1244 is located. This increases the amount of light incident into the light-transmitting groove 1244, thereby increasing the brightness of the light displayed in the first light-transmitting area 132. This achieves the technical effects of optimizing the light path, optimizing the lighting effect, and reducing the energy consumption of the light-emitting component 150.

[0075] Specifically, the light-shielding component 160 is a thermoplastic resin (Polyethylene terephthalate, PET) gasket, and the light-shielding layer 162 is a PET film.

[0076] In some embodiments, the light-shielding bracket 112 and the light-transmitting bracket 114 are optionally an integral structure.

[0077] In this embodiment, the light-shielding bracket 112 and the light-transmitting bracket 114 are formed by an integral molding process.

[0078] Specifically, the light-shielding bracket 112 and the light-transmitting bracket 114 are made of rubber. The light-shielding bracket 112 and the light-transmitting bracket 114 are formed by a two-color injection molding process, so that a black light-shielding bracket 112 is formed on the inside of the bracket 110, and a transparent light-transmitting bracket 114 is formed on the outside of the light-shielding bracket 112.

[0079] Processing the bracket 110 using an integrated molding process can reduce the complexity of the manufacturing process and assembly, thereby reducing the production cost of the bracket 110. Furthermore, the integrated structure has higher strength and better stability. In the event of a collision, the light-shielding bracket 112 and the light-transmitting bracket 114 will not disintegrate, thereby improving the structural stability of the bracket 110 and reducing the failure rate of the lens assembly 100.

[0080] As shown in Figures 3, 5 and 8, in some embodiments, optionally, the light guide component 140 is strip-shaped, and inside the decorative ring assembly 120, the light guide component 140 is annular, and the annular light guide component 140 is disposed along the inner edge of the decorative ring assembly 120; in the radial direction of the decorative ring assembly 120, the light guide component 140 is located between the light-emitting component 150 and the decorative ring assembly 120.

[0081] In this embodiment, the light guide component 140 is strip-shaped. Specifically, a strip-shaped light guide component 140 with a circular cross-section can be selected to conduct light. After the light enters the end face of the strip-shaped light guide component 140, it will undergo two effects: reflection and transmission inside the light guide component 140. The reflected light will continue to be conducted along the length of the strip-shaped light guide component 140, while the transmitted light will be transmitted through the peripheral side of the light guide component 140 to the inclined surface 1242 of the inner ring 124, and then reflected by the inclined surface 1242 and directed to the first light-transmitting area 132 on the cover plate 130.

[0082] Specifically, the light guide component 140 is at least partially disposed along the inner edge of the inner ring 124, allowing the outer ring surface of the light-transmitting bracket 114 to rest against the inner ring surface of the inner ring 124. The wall thickness of the light-transmitting bracket 114 between the light guide component 140 and the inner ring 124 is the spacing between the light guide component 140 and the inner ring 124. Where structural strength and manufacturing processes permit, reducing the spacing between the light guide component 140 and the inner ring can shorten the light path, thereby reducing light loss during transmission, increasing the display brightness of the first light-transmitting area 132, and reducing the energy consumption of the light-emitting component 150.

[0083] Specifically, with the space inside the inner ring 124 defined as the assembly space, the light-emitting component 150 is arranged in the central area of ​​the assembly space, and the light-guiding component 140 is arranged in the edge area of ​​the assembly space. This arrangement can, on the one hand, make reasonable use of the space inside the inner ring 124 to improve the structural compactness of the lens assembly 100 and provide convenient conditions for the miniaturization design of the lens assembly 100; on the other hand, it makes it easier to shorten the distance between the light-guiding component 140 and the inner ring 124, thereby increasing the brightness of the first light-transmitting area 132 and reducing the energy consumption of the light-emitting component 150.

[0084] As shown in Figures 8 and 9, in some embodiments, optionally, the light-emitting component 150 includes: a connector 152 disposed on the bracket 110, the peripheral side of the connector 152 including an interface 1522, and the end of the light guide component 140 inserted into the interface 1522; a circuit board 154 connected to the connector 152; and a light-emitting component 156 disposed on the circuit board 154, the light-emitting component 156 being used to inject light into the interface 1522.

[0085] In this embodiment, the light-emitting component 150 includes a connector 152 and a circuit board 154. The connector 152 is mounted on the bracket 110, and the circuit board 154 is mounted inside the connector 152. The connector 152 is provided with an interface 1522, the shape and size of which are adapted to the light guide component 140. The end of the light guide component 140 can be inserted into the interface 1522, thereby fixing the light guide component 140 through the interface 1522.

[0086] The circuit board 154 is provided with a light-emitting component 156. After assembly, the interface 1522 is opposite to the light-emitting component 156. The light emitted by the light-emitting component 156 can directly shine into the interface 1522 and be received by the end face of the light guide component 140 inserted into the interface 1522.

[0087] It can be seen that the connector 152 can provide positioning and protection for the light guide component 140 and the circuit board 154, ensuring that the light-emitting component 156 on the circuit board 154 can illuminate the end face of the light guide component 140, thereby achieving the technical effect of improving the assembly accuracy of the light guide component 140 and the circuit board 154.

[0088] Specifically, the light-emitting component 156 is a light-emitting diode (LED).

[0089] Specifically, circuit board 154 is a flexible printed circuit (FPC).

[0090] As shown in Figures 4, 10, 11, 13 and 14, in some embodiments, optionally, two interfaces 1522 are inserted into both ends of the light guide component 140, and each interface 1522 is arranged opposite to a light-emitting component 156.

[0091] There are multiple light guide components 140, which are distributed around the connector 152 (shown by arrow c in Figure 4).

[0092] In this embodiment, the strip-shaped light guide component 140 includes two ends, and the number of light guide components 140 is N. The periphery of the connector 152 is provided with 2N interfaces 1522, where N is an integer greater than 1. During assembly, the two ends of the light guide component 140 are respectively inserted into two adjacent interfaces 1522, so that the light guide component 140 curls around the periphery of the connector 152. The shape of the curled light guide component 140 matches the shape of the inner ring surface of the inner ring 124, thereby uniformly illuminating the inclined surface 1242 on the inner ring 124.

[0093] N light guide components 140 are distributed around the connector 152 to provide omnidirectional illumination to the annular inclined surface 1242 on the inner ring 124.

[0094] Based on this, 2N light-emitting components 156 are provided on the circuit board 154. Each light-emitting component 156 is positioned opposite to an interface 1522. After assembly, the same light guide component 140 is illuminated by two light-emitting components 156, thereby increasing the brightness of the light guide component 140 and correspondingly increasing the display brightness of the first light-transmitting area 132, thus optimizing the lighting display effect of the lens assembly 100.

[0095] Specifically, there are two light guide components 140. One light guide component 140 occupies the upper half of the mounting space inside the inner ring 124, and the other light guide component 140 occupies the lower half of the mounting space. Two parallel interfaces 1522 are respectively provided on the left and right sides of the connector 152. Four LEDs are provided on the circuit board 154, and the four LEDs correspond one-to-one with the four interfaces 1522.

[0096] As shown in Figures 12, 13 and 14, in some embodiments, optionally, the connector 152 on the side facing the cover plate 130 or the side of the connector 152 away from the cover plate 130 also includes an injection port 1524, and the interface 1522 communicates with the injection port 1524.

[0097] In this embodiment, the connector 152 is also provided with a glue injection port 1524. The glue injection port 1524 is opened on the upper or lower side of the connector 152. The glue injection port 1524 is cross-connected with the interface 1522. After the end of the light guide component 140 is inserted into the interface 1522, the light guide component 140 can be observed in the glue injection port 1524.

[0098] During assembly, the light guide component 140 is first inserted into the interface 1522, and then glue is injected into the glue injection port 1524. The glue flows through the glue injection port 1524 into the gap between the light guide component 140 and the interface 1522. After solidification, the inner wall surfaces of the light guide component 140 and the interface 1522 are bonded together to fix the light guide component 140 and prevent the light guide component 140 from coming out of the interface 1522, thereby achieving the technical effect of reducing the failure rate of the lens assembly 100.

[0099] Specifically, the light guide component 140 and the connector 152 can be assembled with the aid of the assembly fixture 300 and the positioning block 304. The assembly fixture 300 has a recessed assembly groove 302, the shape of which matches the outer contour of the correctly assembled light guide component 140 and the connector 152. After the assembly fixture 300 inserts both ends of the light guide component 140 into the interface 1522, the light guide component 140 and the connector 152 are pressed into the assembly groove 302. The assembly fixture 300 also includes a receiving groove for the positioning block 304, which communicates with the assembly groove 302 and is located between two adjacent light guide components 140. The receiving groove is used to press the positioning block 304 in. The mounting groove 1142 and the positioning block 304 can together shape the light guide component 140, ensuring that the shape of the light guide component 140 matches the shape of the mounting groove 1142 on the light-transmitting bracket 114. Subsequently, glue is injected into the glue injection port 1524 to fix the light guide component 140 onto the connector 152. Then, the light guide component 140 and the connector 1522 connected together can be removed from the assembly mold.

[0100] By setting the assembly fixture 300 and positioning block 304, the assembly difficulty of the connector 152 and the light guide component 140 can be reduced and the assembly accuracy of the light guide component 140 and the connector 152 can be improved.

[0101] As shown in Figures 13, 14 and 15, in some embodiments, the connector 152 may optionally include a first slot 1526 through which a circuit board 154 passes. The circuit board 154 is able to pass through the first slot 1526 from the side of the connector 152 facing the cover plate 130.

[0102] In this embodiment, a through-hole plug-in scheme for forward mounting of circuit board 154 is proposed.

[0103] Specifically, the connector 152 is provided with a first slot 1526 that extends longitudinally through the connector 152. The shape of the first slot 1526 is adapted to the shape of the circuit board 154. During the assembly process, the circuit board 154 can be inserted into the first slot 1526 from the side facing the cover plate 130 until the lower end of the circuit board 154 passes through the first slot 1526, so that the circuit board 154 can be wired below the connector 152.

[0104] A positioning hole 1544 is provided on the circuit board 154 located below the connector 152. After the circuit board 154 passes through the connector 152 in the forward direction, the positioning post 1529 at the bottom of the connector 152 is inserted into the positioning hole 1544 to complete the first positioning. At the same time, the limiting rib 1542 on the circuit board 154 can cooperate with the connector 152 to perform a second positioning. This through-type plug-in solution allows the circuit board 154 to be installed and removed from above the bracket 110 without disassembling the bracket 110, which helps to reduce the assembly and maintenance difficulty of the circuit board 154.

[0105] As shown in Figures 16 and 17, in some embodiments, optionally, a second slot 1528 is provided on the side of the connector 152 facing away from the cover plate 130, and part of the circuit board 154 and the light-emitting component 156 are inserted into the second slot 1528.

[0106] In this embodiment, a non-through-hole connection scheme for reverse mounting of circuit board 154 is proposed.

[0107] Specifically, considering that the circuit board 154 needs to be wired at the bottom of the connector 152, a second slot 1528 is provided on the side of the connector 152 facing away from the cover plate 130. The shape of the second slot 1528 is adapted to the top of the circuit board 154. During the assembly process, the top of the circuit board 154 can be inserted into the second slot 1528 to complete the assembly.

[0108] In this insertion scheme, the circuit board 154 does not need to pass entirely through the connector 152, but can be inserted from the bottom of the connector 152. This reduces the size of the interface 1522, allowing the connector 152 to occupy less space, thus facilitating the miniaturization of the lens assembly 100. The inner wall of the second slot 1528 has a latch 1546, and the circuit board 154 has a latch. After the circuit board 154 is inserted into the second slot 1528, the latch engages with the latch 1546, completing the first layer of fixation for the circuit board 154. The circuit board 154 located below the connector 152 has a positioning hole 1544. After the circuit is inserted into the second slot 1528, the positioning post 1529 at the bottom of the connector 152 is inserted into the positioning hole 1544, completing the second layer of positioning.

[0109] As shown in Figure 1, in some embodiments, optionally, the cover plate 130 further includes a second light-transmitting area 134, the first light-transmitting area 132 surrounds the second light-transmitting area 134, and the lens assembly 100 further includes an image acquisition device connected to the bracket 110, with the second light-transmitting area 134 disposed opposite to the image acquisition device.

[0110] In this technical solution, a second light-transmitting area 134 is also provided on the cover plate 130. The second light-transmitting area 134 is in the shape of a circular hole, and the first light-transmitting area 132 surrounds the second light-transmitting area 134.

[0111] The lens assembly 100 also includes an image acquisition unit, which can capture light from the outside of the cover plate 130 through the second light-transmitting area 134, thereby completing the acquisition of image information to meet the user's photography needs, image information scanning needs, or video call needs.

[0112] Specifically, the lens assembly 100 also includes a third adhesive component 126, which adhesively bonds the cover plate 130 and the outer ring 122.

[0113] The lens assembly 100 also includes a fourth adhesive component 128, which adhesively bonds the outer ring 122 and the bracket 110.

[0114] The lens assembly 100 also includes a sixth adhesive component 158, which adhesively bonds the bracket 110 and the connector 152.

[0115] As shown in Figures 1, 2 and 3, in some embodiments, an electronic device 200 is proposed, which includes: a housing 210; a lens assembly 100 as in any of the above embodiments; and a bracket 110 connected to the housing 210.

[0116] In this embodiment, an electronic device 200 including the lens assembly 100 in any of the above embodiments is proposed. Therefore, the electronic device 200 has the advantages of the lens assembly 100 in any of the above embodiments and can achieve the technical effects that the lens assembly 100 in any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0117] Based on this, the electronic device 200 includes a housing 210, which includes a battery cover for a mobile phone. The battery cover has a through hole, and the lens assembly 100 is fitted into the through hole. The bracket 110 is bonded to the battery cover via a first adhesive component 116.

[0118] The electronic device 200 can be a terminal or other devices besides a terminal. For example, the electronic device 200 can be a mobile phone, tablet computer, laptop computer, handheld computer, in-vehicle electronic device 200, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a personal computer (PC), television (TV), ATM, or self-service machine, etc. The embodiments of this application do not specifically limit it.
