Description

Technical Field

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

[0002] With the continuous updates and iterations of electronic devices such as mobile phones and tablets, users have increasingly higher requirements for the appearance design and user experience of electronic devices. As an important auxiliary component for the photography function of electronic devices, the flash module usually adopts a ring structure. This structure not only gives the electronic device a unique appearance, but also improves the shooting experience through softer fill light.

[0003] In related technologies, ring-shaped flash modules typically include a lamp cover and a shield, with the shield bonded to the center of the lamp cover to achieve a soft fill light effect. However, the size of existing flash modules is gradually shrinking, which also reduces the adhesive area of ​​the shield. An excessively small adhesive area can lead to weak adhesion of the shield, making it prone to detachment or loosening, thus affecting the reliability and stability of the flash module. Utility Model Content

[0004] This application aims to provide a flash module and electronic device to address the problem that as the size of existing flash modules gradually shrinks, the adhesive area of ​​the shielding component also shrinks. When the adhesive area is too small, the shielding component will not be firmly bonded, and problems such as the shielding component falling off or loosening will easily occur, which will affect the reliability and stability of the flash module.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, this application discloses a flash module, the flash module comprising: A lampshade, wherein the lampshade is provided with a first through hole; A shielding member is disposed on the first side of the lampshade and covers the first through hole; The lampshade is provided on the second side and in the first through hole. The lampshade is connected to the shielding member and the lampshade to fix the shielding member to the lampshade.

[0006] In this embodiment, the flash module includes a lamp cover, a shield, and a fixing member. The shield is adhered to the lamp cover, and the fixing member is connected to both the shield and the lamp cover. In this way, while the shield is adhered to the lamp cover, it is also connected between the lamp cover and the shield through the fixing member. This allows the shield to be firmly fixed to the lamp cover, thereby improving the connection reliability between the shield and the lamp cover and reducing the occurrence of problems such as shield detachment or loosening. This improves the overall reliability and stability of the flash module.

[0007] Secondly, this application also discloses an electronic device, the electronic device comprising: a housing, a flash module as described in any of the above claims, and a decorative ring, the housing having a second through hole, the decorative ring being disposed in the second through hole, the decorative ring having a third through hole, and the lampshade of the flash module being disposed in the third through hole.

[0008] In the electronic device provided in this application embodiment, the flash module includes a lamp cover, a shield, and a fixing member. The shield is disposed on the first side of the lamp cover and covers the through hole on the lamp cover. The fixing member is disposed on the second side of the lamp cover and is disposed in the through hole. The fixing member is connected to the shield and the lamp cover respectively. In this way, the shield can be firmly fixed to the lamp cover by the fixing member connecting the lamp cover and the shield. As the size of the flash module gradually shrinks, the connection reliability between the shield and the lamp cover can be improved, and the occurrence of problems such as shield falling off or loosening can be reduced, thereby improving the overall reliability and stability of the flash module.

[0017] With the continuous updates and iterations of electronic devices 2 such as mobile phones and tablets, users have increasingly higher requirements for the appearance design and user experience of these devices. Electronic devices 2 are typically equipped with a flash module 1 and a camera module 21. The camera module 21 is used to realize functions such as taking pictures, recording videos, and scanning recognition. The flash module 1, as an important auxiliary component for the camera function, can provide supplementary lighting for the camera module 21 through its own emitted illumination beam, thereby improving the image quality of the camera module 21, especially in low-light environments. The flash module 1 can adopt a ring structure. A ring-shaped flash module 1 has a unique appearance that can blend into the overall design of the electronic device 2, enhancing its aesthetics. At the same time, the ring structure design also allows the flash module 1 to produce ring-shaped light, making the light softer and more uniform, avoiding areas that are too bright or too dark, thus further improving the shooting experience.

[0018] In related technologies, a ring-shaped flash module 1 typically includes a lampshade 11, a shield 12, and a flash 16. The lampshade 11 and the flash 16 are stacked, and the shield 12 is connected to the middle area of ​​the lampshade 11. The shield 12 blocks the light from the flash 16 to generate ring light, achieving a soft fill light effect. However, the shield 12 is usually bonded to the lampshade 11 by an adhesive 17, requiring a sufficiently large adhesive area to ensure the reliable connection between the shield 12 and the lampshade 11. As the number and size of cameras in the electronic device 2 gradually increase, the space of the flash module 1 is gradually occupied by the camera module 21, meaning the size of the flash module 1 is gradually decreasing. This causes the adhesive area of ​​the shield 12 to also decrease. If the adhesive area is too small, the shield 12 will not be firmly bonded, making it prone to detachment or loosening under scenarios such as drops or collisions, thus affecting the reliability and stability of the flash module 1.

[0019] Based on the above analysis, this application provides a flash module 1 to at least solve the aforementioned technical problems. The flash module 1 of this application will now be described in detail with reference to the accompanying drawings.

[0020] Reference Figures 1-8This illustration shows a flash module 1 provided in an embodiment of this application. Specifically, the flash module 1 provided in this embodiment may include: a lampshade 11 having a first through hole 114; a shielding member 12 disposed on a first side 111 of the lampshade 11 and covering the first through hole 114; and a fixing member 13 disposed on a second side 112 of the lampshade 11 and within the first through hole 114. The fixing member 13 is connected to both the shielding member 12 and the lampshade 11 to fix the shielding member 12 to the lampshade 11.

[0021] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the flash module 1 also includes a flash lamp 16, which is located on the second side 112 of the lamp cover 11. The projection of the flash lamp 16 on the first side 111 of the lamp cover 11 is outside the shielding member 12. That is, the light emitted by the flash lamp 16 enters from the second side 112 of the lamp cover 11 and can be directly emitted through the first side 111 of the lamp cover 11 without being blocked by the shielding member. There can be one or more flash lamps 16, and this embodiment does not specifically limit this. The flash lamp 16 can be a light-emitting diode (LED) or a xenon lamp, or other light-emitting devices.

[0022] The lampshade 11 can be made of transparent material so that the light emitted by the flash 16 can pass through the lampshade 11. At the same time, the shape of the lampshade 11 can be designed as a ring, square or other shapes according to actual needs to adapt to the appearance design of different electronic devices 2.

[0023] like Figure 1 As shown, the lampshade 11 includes a first side 111 and a second side 112 disposed opposite to each other along a first direction Z, wherein the first direction Z is the thickness direction of the electronic device 2, and the first direction Z is as follows: Figure 1 The Z-axis direction indicated by the middle arrow, the first direction Z, also applies in the following embodiments. The lampshade 11 is provided with a first through hole 114, which penetrates the lampshade 11 along the first direction Z.

[0024] The lampshade 11 has a central region and a light-emitting region surrounding the central region. The central region is used to mount a blocking member 12 to block the light from the flash lamp 16. The light-emitting region is positioned opposite the flash lamp 16 to allow the light from the flash lamp 16 to pass through, achieving a ring-shaped light emission effect. The central region can be circular, elliptical, or similar, and the light-emitting region can be annular.

[0025] like Figure 1As shown, the shielding member 12 can be made of an opaque or semi-transparent material, such as metal, and its shape is adapted to the middle area of ​​the lampshade 11. The shielding member 12 is disposed in the middle area of ​​the first side 111 of the lampshade 11 so that the shielding member 12 can block the light emitted by the flash lamp 16, thereby achieving a ring light effect.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the fixing member 13 is disposed on the second side 112 of the lampshade 11 and is disposed in the first through hole 114. The fixing member 13 is connected to the shielding member 12 located on the first side 111 of the lampshade 11, and the fixing member 13 is connected to the lampshade 11 so as to fix the shielding member 12 more securely to the lampshade 11 through the fixing member 13.

[0027] In this embodiment, the flash module 1 includes a lamp cover 11, a shield 12, and a fixing member 13. The shield 12 is disposed on the first side 111 of the lamp cover 11 and covers the first through hole 114 on the lamp cover 11. The fixing member 13 is disposed on the second side 112 and is disposed in the first through hole 114. The fixing member 13 is connected to the shield 12 and the lamp cover 11 respectively. In this way, the fixing member 13 connects the lamp cover 11 and the shield 12, so that the shield 12 can be firmly fixed on the lamp cover 11. As the size of the flash module 1 gradually decreases, the connection reliability between the shield 12 and the lamp cover 11 can be improved, and the occurrence of problems such as the shield 12 falling off or loosening can be reduced, thereby improving the overall reliability and stability of the flash module 1.

[0028] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the shielding member 12 can be pre-fixed to the middle area of ​​the first side 111 of the lampshade 11 by the adhesive member 17. Thus, when installing the fixing member 13, since the shielding member 12 has been pre-fixed by the adhesive member 17, its position is relatively stable, facilitating the subsequent installation of the fixing member 13. Furthermore, since the adhesive member 17 only performs a pre-fixing function, compared to the fully adhesive solution in related technologies, the adhesive area can be significantly reduced, thus reducing the area of ​​the lampshade 11. This reduces the stacking space of the flash module 1 along the second and third directions, making the position design of the lampshade 11 more flexible. The third direction, the second direction, and the first direction Z are all perpendicular to each other.

[0029] In some alternative embodiments, a first groove 113 is provided on the first side 111 of the lampshade 11, and the bottom of the first groove 113 is connected to the first through hole 114; at least a portion of the shielding member 12 is disposed in the first groove 113, wherein the fixing member 13 passes through the first through hole 114 from the second side 112 and is connected to the shielding member 12.

[0030] Specifically, such as Figure 1 As shown, a first groove 113 is provided in the middle region of the first side 111 of the lampshade 11. The first groove 113 is recessed along the first direction Z. The size of the first groove 113 is slightly larger than the size of the shielding member 12, so that at least part of the shielding member 12 can be embedded in the first groove 113. The shape of the first groove 113 is adapted to the shape of the shielding member 12. The shape of the first groove 113 and the shape of the shielding member 12 can be designed as a circle, square, etc., according to actual needs. This application embodiment does not make specific limitations in this regard.

[0031] In practical applications, by setting a first groove 113, the bottom of which connects to a first through hole 114, at least part of the shielding member 12 can be disposed within the first groove 113. This reduces the thickness of the flash module 1 along the first direction Z, making the overall structure of the flash module 1 more compact and reasonable. Furthermore, the fixing member 13 passes through the first through hole 114 from the second side 112 of the lamp cover 11 and connects to the shielding member 12. The fixing member 13 can pull the shielding member 12 tight from the second side 112 of the lamp cover 11, thereby further improving the connection reliability between the shielding member 12 and the lamp cover 11.

[0032] In some embodiments, the blocking member 12 can be entirely disposed within the first groove 113. Specifically, the blocking member 12 can be a sheet-like structure, the shape and size of which are adapted to the shape and size of the first groove 113, so that the entire blocking member 12 can be disposed within the first groove 113, thus simplifying the structure of the blocking member 12. In another embodiment, such as... Figure 1 , Figure 2 and Figure 5 As shown, the shielding member 12 can be divided into two parts. One part is set inside the first groove 113, and the other part is set inside the first through hole 114. In this way, the connection area between the fixing member 13 and the shielding member 12 and the lampshade 11 can be increased, thereby further improving the connection reliability between the shielding member 12 and the lampshade 11.

[0033] In some alternative embodiments, the shielding member 12 includes a shielding portion 121 and an extension portion 122 connected to each other; the extension portion 122 extends into the first through hole 114; wherein the fixing member 13 is connected to the lampshade 11 on the second side 112 and extends from the second side 112 to the first side 111 and is connected to the extension portion 122.

[0034] Specifically, such as Figure 1 As shown, the shielding member 12 includes a shielding part 121 and an extension part 122 that are connected to each other along the first direction Z. The shielding part 121 is used to shield the light of the flash lamp 16 to achieve a ring light effect. The extension part 122 is used to connect with the fixing member 13 so that the shielding part 121 and the extension part 122 are fixed on the lamp cover 11 by the fixing member 13.

[0035] The shielding portion 121 can be a shielding plate, the shape and size of which are adapted to the shape and size of the first groove 113 so that the shielding portion 121 can be disposed inside the first groove 113. In some embodiments, the shielding portion 121 can be pre-fixed to the bottom of the first groove 113 by means of an adhesive 17.

[0036] The bottom of the first groove 113 communicates with the first through hole 114. The size of the first through hole 114 is slightly larger than the size of the blocking part 121, so that the extension part 122 can extend into the first through hole 114 along the first direction Z. The length of the extension part 122 along the first direction Z in the first through hole 114 can be specifically set according to actual needs, as long as the connection between the extension part 122 and the fixing member 13 can be realized. This application embodiment does not make specific limitations in this regard. The shape of the extension part 122 and the shape of the first through hole 114 can be the same or different, and can be specifically set according to actual needs.

[0037] like Figure 1 As shown, the fastener 13 can be connected to the surface of the second side 112 of the lampshade 11, and the fastener 13 extends from the second side 112 toward the first side 111 within the first through hole 114 and is connected to the extension 122. Or as Figure 2 and Figure 5 As shown, the fastener 13 is connected to the lampshade 11 on the second side 112, and the fastener 13 extends from the second side 112 toward the first side 111 in the first through hole 114, and is connected to the hole wall of the first through hole 114 and the outer peripheral side of the extension 122, so that the shielding member 12 can be firmly fixed on the lampshade 11.

[0038] In practical applications, by connecting an extension 122 to the shielding part 121, the extension 122 extends into the first through hole 114, and is connected to the lampshade 11 on the second side 112 by the fixing member 13, and extends from the second side 112 to the first side 111 and is connected to the extension 122, the connection area between the fixing member 13 and the shielding member 12 and the lampshade 11 can be increased, thereby further improving the connection reliability between the shielding member 12 and the lampshade 11.

[0039] In some embodiments, the extension 122 is provided with a threaded hole 1211 on the side away from the shielding part 121; the fastener 13 is a fastener 131, which is threaded into the threaded hole 1211 and abuts against the lampshade 11.

[0040] Specifically, such as Figure 1 As shown, the extension 122 extends along the first direction Z, and a threaded hole 1211 is provided on the side of the extension 122 away from the shielding part 121. The threaded hole 1211 extends upward along the first direction Z, and a first thread is provided on the inner wall of the threaded hole 1211.

[0041] The fastener 13 is a fastener 131, which can be a bolt, screw, etc. The fastener 131 includes a head and a rod that are connected to each other. The rod has a second thread that matches the first thread of the threaded hole 1211. The first thread and the second thread engage with each other, allowing the fastener 131 to be threaded into the threaded hole 1211. When the rod is screwed into the threaded hole 1211, the head abuts against the second side 112 surface of the lampshade 11, thereby securely fixing the extension 122 to the lampshade 11.

[0042] In this embodiment, a threaded hole 1211 is provided on the extension 122, and the fastener 13 is a fastener 131. The fastener 131 is threaded into the threaded hole 1211 and abuts against the lamp cover 11. In this way, the connection and disassembly between the fastener 13 and the extension 122 can be easily realized through the threaded connection, which facilitates the assembly and maintenance of the flash module 1. At the same time, the threaded connection has better connection reliability, which can further improve the connection reliability between the shield 12 and the lamp cover 11 and reduce the occurrence of problems such as the shield 12 falling off or loosening.

[0043] In some optional embodiments, the flash module 1 further includes a gasket 14, which is fitted onto the rod portion of the fastener 131 and located between the head of the fastener 131 and the surface of the second side 112 of the lamp cover 11. Specifically, when the fastener 131 is threaded into the threaded hole 1211 of the extension 122, the gasket 14 is pressed by the head of the fastener 131 and the surface of the second side 112 of the lamp cover 11. On the one hand, the gasket 14 can fill the tiny gap between the head of the fastener 131 and the surface of the second side 112 of the lamp cover 11, making the connection between the fastener 131 and the lamp cover 11 tighter and further enhancing the stability of the connection; on the other hand, the gasket 14 can act as a buffer, absorbing part of the impact force when the electronic device 2 is subjected to external forces such as drops or collisions, reducing the impact on the connection between the shield 12 and the lamp cover 11, reducing the risk of the shield 12 falling off or loosening, thereby better protecting the structural integrity of the flash module 1 and improving its reliability and stability. In addition, the shim 14 can prevent the head of the fastener 131 from directly contacting the surface of the lampshade 11, thus preventing wear on the surface of the lampshade 11 due to long-term friction and extending the service life of the lampshade 11.

[0044] In some alternative embodiments, there is a gap between the extension 122 and the wall of the first through hole 114; the fastener 13 is an adhesive layer structure 132 filled in the gap.

[0045] Specifically, such as Figure 1 As shown, the size of the first through hole 114 is larger than the size of the extension 122. Thus, when the extension 122 passes through the first through hole 114, an annular gap is formed between the extension 122 and the wall of the first through hole 114.

[0046] The adhesive can be injected into the gap from the opening of the first through hole 114 near the second side 112. After curing, it forms a stable adhesive layer structure 132. This adhesive layer structure 132 can serve as a fixing member 13, filling the gap between the extension 122 and the wall of the first through hole 114, and tightly bonding the extension 122 and the wall of the first through hole 114 together, thereby achieving a stable connection between the shielding member 12 and the lampshade 11.

[0047] The adhesive layer structure 132 can be made of materials with good adhesion and curing properties, such as epoxy resin or silicone. This application embodiment does not specify this.

[0048] In this embodiment, by making the fixing member 13 an adhesive layer structure 132, which fills the space between the extension 122 and the wall of the first through hole 114, this method of using the adhesive layer structure 132 as the fixing member eliminates the need for complex mechanical structures, simplifies the assembly process of the flash module 1, and reduces production costs. Furthermore, the adhesive layer structure 132 can fill irregular gaps between the extension 122 and the wall of the first through hole 114, adapting to extensions 122 and first through holes 114 of different shapes and sizes, further improving connection reliability and stability.

[0049] In some alternative embodiments, a second groove 1221 is provided on the outer peripheral side of the extension 122, and the adhesive layer structure 132 is at least partially filled in the second groove 1221.

[0050] Specifically, such as Figure 3 As shown, a second groove 1221 is provided on the outer periphery of the extension 122 along its circumferential direction. The shape of the second groove 1221 can be designed according to actual needs, such as an annular groove. There can also be multiple second grooves 1221, which are spaced apart.

[0051] When the adhesive is injected into the gap between the extension 122 and the wall of the first through hole 114, some of the adhesive will flow into the second groove 1221. After the adhesive cures to form the adhesive layer structure 132, as... Figure 2 As shown, the adhesive layer structure 132 not only fills the gap between the extension 122 and the wall of the first through hole 114, but also at least partially fills the second groove 1221.

[0052] In practical applications, by providing a second groove 1221 on the extension 122 and filling the second groove 1221 with the adhesive layer structure 132, the connection area between the adhesive layer structure 132 and the extension 122 can be increased, allowing the adhesive layer structure 132 to bond the extension 122 more firmly. This further enhances the connection reliability between the shield 12 and the lamp cover 11, and further reduces the possibility of loosening or separation between the extension 122 and the first through hole 114. As a result, the reliability and stability of the flash module 1 are further improved, and its service life is extended.

[0053] In some alternative embodiments, the fixing member 13 is a flexible member 133; the flexible member 133 is disposed in the first through hole 114 and connected to the hole wall of the first through hole 114; the flexible member 133 is provided with an embedding groove 1331, and the extension 122 is correspondingly provided with an embedding part 1222, which is embedded in the embedding groove 1331.

[0054] Specifically, such as Figure 5As shown, the lampshade 11 can be made of a rigid material, and the fixing member 13 can be a flexible member 133 made of an elastic material. The flexible member 133 is disposed in the first through hole 114. The flexible member 133 can be tightly connected to the hole wall of the first through hole 114 by various means such as bonding and snapping, so that the flexible member 133 is fixed in the first through hole 114.

[0055] The flexible member 133 is provided with an insert groove 1331, and the extension 122 is provided with an insert part 1222. The shape and size of the insert groove 1331 match the insert part 1222. When assembled, the insert part 1222 can be inserted into the insert groove 1331, so that the flexible member 133 and the extension 122 are connected.

[0056] In practical applications, by making the fixing member 13 a flexible member 133, when assembling the flash module 1, the flexible member 133 is first placed in the first through hole 114, and then the light-shielding part is embedded in the first groove 113, the extension 122 is inserted into the first through hole 114, and the embedding part 1222 is inserted into the embedding groove 1331. Since the flexible member 133 is soft and has a certain elasticity, the flexible member 133 can deform during the process of the embedding part 1222 being inserted into the embedding groove 1331, so that the embedding part 1222 can be smoothly embedded into the embedding groove 1331. After embedding, the flexible member 133 can recover part of the deformation, thereby producing a certain wrapping and fastening effect on the embedding part 1222, further enhancing the connection reliability between the extension part 122 and the flexible member 133. Meanwhile, the tight connection between the flexible component 133 and the wall of the first through hole 114, and the embedded connection between the extension 122 and the flexible component 133, together securely fix the shield 12 to the lamp cover 11, further reducing the risk of the shield 12 falling off or loosening. In addition, the flexible component 133 can also play a certain buffering role. When the electronic device 2 is subjected to external impact, the flexible component 133 can absorb part of the impact force, reduce the impact on the connection between the shield 12 and the lamp cover 11, protect the structural integrity of the flash module 1, and improve its reliability and stability.

[0057] In some embodiments, the flexible component 133 is connected to the lampshade 11 via a nano-injection molding process. Specifically, as... Figure 6As shown, the flexible component 133 can be a plastic structure. In the specific manufacturing process, a first through hole 114 can be opened at the bottom of the first groove 113, and then a flexible component 133 with an embedding groove 1331 can be formed on the inner wall of the first through hole 114 through a nano-injection molding process, so that the flexible component 133 and the lamp cover 11 become an integral structure. This can enhance the connection strength between the flexible component 133 and the lamp cover 11, effectively prevent the extension 122 from shaking or falling off in the first through hole 114, and further improve the connection reliability between the two. In addition, no additional assembly process is required, so the assembly process of the flash module 1 can be simplified, production efficiency can be improved, and production costs can be reduced. Moreover, it can also make the overall structure of the flash module 1 more compact and beautiful, and improve the appearance quality of the product.

[0058] Optionally, a protrusion 1332 is provided on the groove wall of the embedding groove 1331, and a recess 1223 is provided at the position corresponding to the protrusion 1332 of the embedding part 1222, and the protrusion 1332 is engaged in the recess 1223.

[0059] like Figure 6 As shown, a protrusion 1332 is provided on the groove wall of the embedded groove 1331 along its circumference. The protrusion 1332 can be a whole annular protrusion or multiple protrusions 1332 spaced apart. These protrusions 1332 can be semi-circular, triangular or other shapes, and the specific shape can be designed according to actual needs.

[0060] like Figure 7 As shown, the recessed portion 1223 is provided at the position corresponding to the protrusion 1332 of the embedded portion 1222. The shape of the recessed portion 1223 is adapted to the shape of the protrusion 1332. It can also be an annular recessed portion 1223, or it can be multiple recessed portions 1223 arranged at intervals. These recessed portions 1223 can be semi-circular, triangular, etc.

[0061] In practical applications, by providing the protrusion 1332 and the recess 1223, when the embedding part 1222 is embedded in the embedding groove 1331, the protrusion 1332 will engage with the recess 1223. This engaging structure can further enhance the connection reliability between the extension 122 and the flexible part 133, preventing the extension 122 from falling out of the embedding groove 1331 when subjected to external impact or vibration. This allows the shielding part 12 to be more securely fixed to the lamp cover 11, further reducing the occurrence of problems such as loosening or displacement of the shielding part 12, improving the overall reliability and stability of the flash module 1, and extending its service life. Moreover, this engaging structure is simple to design, easy to operate during assembly, and can improve production efficiency and reduce production costs.

[0062] In some embodiments, a guide structure 1141 is provided on the side of the first through hole 114 near the second side 112, and the guide structure 1141 is inclined.

[0063] Specifically, such as Figure 4 and Figure 5 As shown, a guide angle is provided on the hole wall of the first through hole 114 near the side wall of the second side 112. The inclined surface of the guide angle is inclined outward from the hole wall of the first through hole 114 toward the surface of the second side 112 of the lamp cover 11. The guide angle constitutes a guide structure 1141, and the guide structure 1141 is inclined relative to the first direction Z.

[0064] In practical applications, the specific tilt angle and shape of the guide structure 1141 can be flexibly designed according to actual needs to achieve the best guiding and bonding effect. This application embodiment does not make specific limitations in this regard.

[0065] In this embodiment, by setting an inclined guide structure 1141, when the fixing member 13 is an adhesive layer structure 132 or a flexible member 133, and the flexible member 133 is connected to the lampshade 11 through a nano-injection molding process, when the fixing adhesive or plastic solution is injected into the gap between the extension 122 and the wall of the first through hole 114, the guide structure 1141 can guide the curing adhesive or plastic solution, so that the curing adhesive or plastic solution can flow more smoothly along the guide structure 1141 during the injection process, thereby better filling the gap between the extension 122 and the wall of the first through hole 114, so that the adhesive layer structure 132 or the flexible member 133 can be formed completely and uniformly. Furthermore, the setting of the guide structure 1141 can also increase the contact area between the adhesive layer structure 132 or the flexible member 133 and the wall of the first through hole 114 to a certain extent, further enhancing the connection reliability between the shielding member 12 and the lampshade 11.

[0066] In summary, the flash module 1 provided in this application embodiment has at least the following advantages: In the electronic device provided in this application embodiment, the flash module includes a lamp cover, a shield, and a fixing member. The shield is disposed on the first side of the lamp cover and covers the through hole on the lamp cover. The fixing member is disposed on the second side of the lamp cover and is disposed in the through hole. The fixing member is connected to the shield and the lamp cover respectively. In this way, the shield can be firmly fixed to the lamp cover by the fixing member connecting the lamp cover and the shield. As the size of the flash module gradually shrinks, the connection reliability between the shield and the lamp cover can be improved, and the occurrence of problems such as shield falling off or loosening can be reduced, thereby improving the overall reliability and stability of the flash module.
