Detailed Implementation

[0011] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0012] 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 use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. 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.

[0013] The decorative ring component and electronic device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0014] refer to Figures 1-24 The decorative ring assembly provided in this application embodiment may include a bracket 200 and a decorative ring 300.

[0015] like Figure 2 , Figure 3 , Figure 14 , Figure 23 and Figure 24 As shown, the bracket 200 can be used to connect to the housing 100 of the electronic device and can be positioned opposite the camera of the electronic device. At least a portion of the decorative ring 300 can be arranged around the bracket 200 to decorate and beautify the electronic device. In this embodiment, the bracket 200 can serve to fix and support, ensuring that the entire decorative ring assembly can be securely installed on the electronic device and is not easily loosened or detached during use.

[0016] For example, such as Figure 11 and Figure 15 As shown, a first light-transmitting hole 260 can be provided on the bracket 200, and the first light-transmitting hole 260 is positioned opposite to the camera, such as... Figure 5As shown, the decorative ring 300 may include a fixing plate 301, on which a second light-transmitting hole 320 may be provided. The second light-transmitting hole 320 may be arranged opposite to the first light-transmitting hole 260 so that light can enter the camera through the second light-transmitting hole 320 and the first light-transmitting hole 260. Figure 2 , Figure 3 , Figure 14 , Figure 23 and Figure 24 As shown, the decorative ring assembly may also include a lens 400, which may be disposed within the decorative ring 300 and connected to the fixing plate 301. Along the axial direction of the decorative ring 300, the orthographic projection of the lens 400 covers the second light-transmitting hole 320 to prevent external dust or liquids from entering the electronic device through the second light-transmitting hole 320 and the first light-transmitting hole 260.

[0017] In this design, one of the bracket 200 and the decorative ring 300 may be provided with a first engaging portion 310, and the other may be provided with a second engaging portion 210 and a first limiting groove 220. The second engaging portion 210 can switch between a first state and a second state. At least a portion of the first engaging portion 310 can be embedded in the first limiting groove 220, and the first engaging portion 310 is engaged with the groove wall of the first limiting groove 220 in the circumferential direction of the decorative ring 300. This configuration can prevent relative movement between the decorative ring 300 and the bracket 200 in the circumferential direction.

[0018] With the second locking portion 210 in the first state, the second locking portion 210 and the first locking portion 310 are engaged in a limiting fit along the axial direction of the decorative ring 300. This arrangement prevents relative movement between the decorative ring 300 and the bracket 200 in the axial direction.

[0019] When the second latching part 210 is in the second state, the second latching part 210 avoids the first latching part 310. This arrangement facilitates the first latching part 310 to disengage from the first limiting groove 220, thereby facilitating the removal of the decorative ring 300.

[0020] In this embodiment, one of the bracket 200 and the decorative ring 300 is provided with a first snap-fit ​​portion 310, and the other is provided with a second snap-fit ​​portion 210 and a first limiting groove 220. At least a portion of the first snap-fit ​​portion 310 is embedded in the first limiting groove 220, and the second snap-fit ​​portion 210 is switched to a first state, so that the second snap-fit ​​portion 210 and the first snap-fit ​​portion 310 are engaged in an axial upper limit engagement with the decorative ring 300. This allows the first snap-fit ​​portion 310 to be kept in the first limiting groove 220. With this configuration, without the need for adhesive backing, glue application, or screw locking, the decorative ring 300 can be effectively prevented from shifting in the axial and circumferential directions, ensuring that the decorative ring 300 is firmly fixed to the bracket 200 during use and is not easily detached due to shaking, collision, or other factors of electronic devices, thus improving the reliability of the decorative ring 300 fixation.

[0021] Furthermore, when assembling the decorative ring 300 and the bracket 200, it is only necessary to insert the first snap-fit ​​part 310 into the first limiting groove 220 and switch the second snap-fit ​​part 210 to the first state, so that the second snap-fit ​​part 210 and the first snap-fit ​​part 310 are engaged in the axial upper limit cooperation of the decorative ring 300, which can realize the quick assembly of the decorative ring 300 and the bracket 200. Compared with the method of fixing with screws or adhesive, the assembly process is simplified, the assembly efficiency is improved, and the production cost can be reduced. At the same time, when the decorative ring 300 is damaged and needs to be replaced, it is only necessary to switch the second snap-fit ​​part 210 to the second state, so that the second snap-fit ​​part 210 can avoid the first snap-fit ​​part 310, and the decorative ring 300 can be easily removed from the bracket 200. The disassembly operation is simple, convenient and quick, which helps to shorten the maintenance time and difficulty of the decorative ring 300 and reduce maintenance costs.

[0022] In one embodiment of this application, the second engaging portion 210 is movably disposed on one of the bracket 200 and the decorative ring 300. The second engaging portion 210 can move along the axial direction of the decorative ring 300 to switch between a first state and a second state. This configuration allows for state switching of the second engaging portion 210 solely through axial movement, i.e., limiting or releasing the first engaging portion 310. The structure is simple and easy to operate. Furthermore, the axial movement of the second engaging portion 210 does not occupy additional radial space, which helps reduce the area occupied by the decorative ring assembly.

[0023] In other embodiments, the second snap-fit ​​portion 210 is rotatably disposed on the bracket 200 or the decorative ring 300.

[0024] In optional embodiments, such as Figure 3As shown, one of the bracket 200 and the decorative ring 300 may also be provided with a second limiting groove 230. The second limiting groove 230 can be disposed opposite to the first limiting groove 220. A portion of the second engaging part 210 is movably disposed within the second limiting groove 230. Furthermore, the second engaging part 210 is engaged with the groove wall of the second limiting groove 230 in the outward direction from the center of the decorative ring 300 and in the circumferential direction of the decorative ring 300. This arrangement can limit the second engaging part 210 in the outward direction from the center of the decorative ring 300 and in the circumferential direction of the decorative ring 300, preventing unnecessary displacement or shaking of the second engaging part 210 in these two directions. Moreover, the second limiting groove 230 can guide the movement of the second engaging part 210, ensuring that the second engaging part 210 can only move along the axial direction of the decorative ring 300, preventing the second engaging part 210 from shifting or jamming. For example, the direction outward from the center of the decorative ring 300 can be the radial direction in which the decorative ring 300 extends outward from the center of the decorative ring 300.

[0025] In other embodiments, the second limiting groove 230 may not be provided on either the bracket 200 or the decorative ring 300.

[0026] In this embodiment, as Figure 3 As shown, the first snap-fit ​​portion 310 can be disposed on the decorative ring 300, and the second snap-fit ​​portion 210, the first limiting groove 220, and the second limiting groove 230 can all be disposed on the bracket 200. For example, the second snap-fit ​​portion 210 can be connected to the bottom of the second limiting groove 230 via an elastic element described below. For example, the decorative ring 300 can be a metal structure, and the bracket 200 can be made of plastic material. The bracket 200 can be formed by injection molding, and the first limiting groove 220 and the second limiting groove 230 can be formed on the bracket 200 by injection molding, thus reducing processing difficulty.

[0027] In an optional embodiment, one of the bracket 200 and the decorative ring 300 may also be provided with a slide groove 240. The slide groove 240 can extend circumferentially along the decorative ring 300, and the first engaging portion 310 can move along the slide groove 240. The slide groove 240 has a first end and a second end in the circumferential direction of the decorative ring 300. The first limiting groove 220 can be located at the second end of the slide groove 240 and can be disposed on one side of the slide groove 240 in the axial direction of the decorative ring 300. The slide groove 240 can communicate with the first limiting groove 220. In this embodiment, the slide groove 240 can provide a clear moving track for the first engaging portion 310. When the decorative ring 300 is installed on the bracket 200, the operator only needs to rotate the decorative ring 300 along the slide groove 240 to make the first engaging portion 310 move smoothly toward the first limiting groove 220. There is no need to manually and precisely align the first engaging portion 310 with the first limiting groove 220, which effectively reduces the difficulty of operation and improves the assembly efficiency. Furthermore, the groove wall of the slide 240 can axially constrain the first snap-fit ​​portion 310, preventing axial movement of the decorative ring 300 during rotational assembly and ensuring that misalignment does not easily occur when assembling the decorative ring 300. In this embodiment, as... Figure 11 As shown, the slide 240 can be mounted on the bracket 200.

[0028] In other embodiments, neither the bracket 200 nor the decorative ring 300 may have the groove 240 provided.

[0029] Optionally, such as Figure 11 As shown, the depth of the groove 240 gradually decreases along the direction from the second end to the first end. With this configuration, when it is necessary to remove the decorative ring 300, the decorative ring 300 is rotated along the direction of decreasing groove depth of the groove 240. The groove 240 can guide the first locking part 310, so that the first locking part 310 can slide out of the groove 240, thereby facilitating the removal of the decorative ring 300.

[0030] Of course, the groove depth of the slide 240 can remain unchanged along the direction from the second end to the first end.

[0031] In optional embodiments, such as Figure 8 and Figure 11As shown, the slide groove 240 has a first groove wall 241, which can be located on one side of the groove opening of the slide groove 240 along the axial direction of the decorative ring 300. Along the direction from the second end to the first end, the distance between the outer edge of the first groove wall 241 and the center line of the bracket 200 gradually decreases, so that the groove depth of the slide groove 240 gradually decreases. It should be noted that the outer edge of the first groove wall 241 refers to its side edge extending circumferentially on the decorative ring 300. With this configuration, when the decorative ring 300 needs to be removed, the decorative ring 300 is rotated in the opposite direction, causing the first locking part 310 to move along the second end of the slide groove 240 towards the first end. When the first locking part 310 reaches the first end of the slide groove 240, it is no longer axially constrained by the first groove wall 241, allowing the first locking part 310 to axially disengage from the slide groove 240. Therefore, in this embodiment, when the decorative ring 300 is disassembled, the first snap-fit ​​part 310 does not need to break free from the groove wall restriction of the slide groove 240 through an additional structure, making it easier to axially separate the decorative ring 300 from the bracket 200.

[0032] Of course, the distance between the outer edge of the first groove wall 241 and the center line of the support 200 can remain unchanged along the direction from the second end to the first end.

[0033] In optional embodiments, such as Figure 12 As shown, the second snap-fit ​​portion 210 may have a first inclined surface 211 on the side facing the first limiting groove 220. Along the direction from the first end to the second end, the distance between the first inclined surface 211 and the first limiting groove 220 in the axial direction of the decorative ring 300 gradually decreases. With this configuration, as the first inclined surface 211 and the first snap-fit ​​portion 310 gradually come into contact and press against each other, the first inclined surface 211 will guide the second snap-fit ​​portion 210 to move axially, making it easier for the second snap-fit ​​portion 210 to avoid the first snap-fit ​​portion 310.

[0034] Of course, the first inclined surface 211 may not be provided on the side of the second snap-fit ​​portion 210 facing the first limiting groove 220.

[0035] In some embodiments, such as Figure 12 As shown, the first snap-fit ​​portion 310 may be provided with a second inclined surface 311, which can contact the second snap-fit ​​portion 210. Along the direction from the first end to the second end, the width of the first snap-fit ​​portion 310 in the axial direction of the decorative ring 300 gradually decreases. With this configuration, when the first snap-fit ​​portion 310 contacts the second snap-fit ​​portion 210 and continues to move, the second inclined surface 311 can apply an axial force to the second snap-fit ​​portion 210, so that the second snap-fit ​​portion 210 can avoid the first snap-fit ​​portion 310.

[0036] Of course, the first snap-fit ​​part 310 may not have the second inclined surface 311.

[0037] In optional embodiments, such as Figure 11As shown, the bracket 200 may also be provided with a disassembly hole 270. The disassembly hole 270 can penetrate the bracket 200 along the axial direction of the decorative ring 300. The disassembly hole 270 can be used for a disassembly tool 900 to pass through, so that the disassembly tool 900 can lift the decorative ring 300, thereby releasing the engagement between the first snap-fit ​​part 310 and the second snap-fit ​​part 210. In this embodiment, the disassembly hole 270 can provide a clear operating space for the disassembly tool 900 to act on the decorative ring 300. When it is necessary to disassemble the decorative ring 300, the operator can pass the disassembly tool 900 through the disassembly hole 270, so that the disassembly tool 900 contacts the decorative ring 300, so as to directly apply a lifting force to the decorative ring 300, so as to disassemble the decorative ring 300. Furthermore, disassembling the decorative ring 300 by lifting it can effectively avoid damage to the decorative ring 300 or the bracket 200 due to forced disassembly, thus protecting the appearance and structural integrity of the decorative ring 300 and the bracket 200. Here, the disassembly tool 900 can be connected to the fixing plate 301.

[0038] In other embodiments, the bracket 200 may not have a disassembly hole 270. For example, the decorative ring 300 can be disassembled by prying, pulling, or other means.

[0039] In some embodiments, the disassembly tool may include a pin or a block, etc.

[0040] In this embodiment of the application, when assembling the decorative ring 300, the decorative ring 300 can be sleeved on the bracket 200, and the first snap-fit ​​part 310 is located at the first end of the slide groove 240. Then, the decorative ring 300 is rotated clockwise, so that the first snap-fit ​​part 310 moves along the slide groove 240 to the second end of the slide groove 240 and is embedded in the first limiting groove 220. At this time, under the action of the second snap-fit ​​part 210, the first snap-fit ​​part 310 is kept in the first limiting groove 220.

[0041] When the decorative ring 300 is damaged and requires after-sales repair or replacement, it needs to be disassembled using a disassembly tool 900. Figure 12 As shown, the disassembly tool 900 is provided with a boss 910. The boss 910 can pass through the disassembly hole 270 on the bracket 200 and contact the decorative ring 300. The disassembly tool 900 lifts the fixing plate 301 of the decorative ring 300, so that the first snap-fit ​​part 310 is disengaged from the first limiting groove 220. Then, the decorative ring 300 is rotated counterclockwise, so that the first snap-fit ​​part 310 slides along the slide groove 240 to the first end of the slide groove 240. Finally, the decorative ring 300 can be removed by pulling it axially.

[0042] In another alternative embodiment of this application, such as Figure 14 , Figure 23 and Figure 24As shown, the second snap-fit ​​portion 210 is rotatably connected to one of the bracket 200 and the decorative ring 300, and the second snap-fit ​​portion 210 can rotate between a first state and a second state. This arrangement reduces the axial space occupied by the second snap-fit ​​portion 210, thereby helping to reduce the thickness of the decorative ring 300.

[0043] In other embodiments, the second snap-fit ​​portion 210 may also be movably connected to the bracket 200 or the decorative ring 300.

[0044] In optional embodiments, such as Figure 14 As shown, the decorative ring assembly may further include an unlocking member 800. At least a portion of the unlocking member 800 may be disposed on one of the bracket 200 and the decorative ring 300. The unlocking member 800 can be used to drive the second latching portion 210 to rotate to a second state. With this configuration, when it is necessary to remove the decorative ring 300, the operator can use the unlocking member 800 to accurately rotate the second latching portion 210 to a position that avoids the first latching portion 310, eliminating the interference between the two and easily separating the second latching portion 210 from the first latching portion 310. This can effectively reduce the difficulty of removing the decorative ring 300 and improve the removal efficiency.

[0045] In other embodiments, the decorative ring assembly may also exclude the unlocking member 800. When removing the decorative ring 300, a tool can be inserted between the decorative ring 300 and the second latching portion 210, and the second latching portion 210 can be pried to rotate to the second state.

[0046] In an optional embodiment, when the second latching portion 210 is a metal structure, the unlocking element 800 may include an electromagnetic element. The electromagnetic element can be mounted on the bracket 200 or the decorative ring 300. When the electromagnetic element is energized, it attracts the second latching portion 210 to rotate to a second state. This configuration eliminates the need for manual rotation or prying of the second latching portion 210; unlocking is achieved simply by controlling the energization of the electromagnetic element, allowing the second latching portion 210 to avoid the first latching portion 310, making the installation and removal of the decorative ring 300 simple and convenient. Furthermore, compared to driving the second latching portion 210 to rotate via a micro-motor (described later), the electromagnetic element directly acts on the second latching portion 210 through a magnetic field, eliminating the need for a complex transmission structure. When arranging the electromagnetic element, it is sufficient to ensure that its magnetic field effectively covers the second latching portion 210, allowing for flexible placement. The electromagnetic element can be positioned appropriately based on available space without affecting other components.

[0047] In another alternative embodiment, when the second latching portion 210 is a non-metallic structure, the unlocking member 800 may include a first magnetic member and a second magnetic member. The first magnetic member may be disposed on the bracket 200 or the decorative ring 300, and the second magnetic member may be disposed on the limiting end of the second latching portion 210, which is the end of the second latching portion 210 that contacts the first latching portion 310. Furthermore, at least one of the first magnetic member and the second magnetic member may be an electromagnetic member. When the electromagnetic member is energized, the second latching portion 210 rotates to the second state. This configuration allows the electromagnetic component to generate a magnetic field when energized. The interaction between the first and second magnetic components drives the second latching part 210 to rotate to the second state without the need for manual adjustment of the position of the second latching part 210, making operation convenient. Furthermore, since the electromagnetic component needs to be energized to generate a magnetic field to drive the second latching part 210 to rotate, when not energized, the second latching part 210 maintains a limited engagement with the first latching part 310, making it less prone to accidental unlocking. This effectively prevents the second latching part 210 from rotating due to external forces such as vibration or collision during normal use, thus preventing the decorative ring 300 from accidentally falling off.

[0048] In other embodiments, the unlocking member 800 may not include an electromagnetic component. For example, the unlocking member 800 includes a micro motor for driving the unlocking member 800 to rotate. The micro motor drives the rotating shaft 212 connected to the second latching part 210 to rotate, which can drive the second latching part 210 to rotate to a second state, avoiding the first latching part 310.

[0049] In an optional embodiment, one of the bracket 200 and the decorative ring 300 may be provided with a relief groove 250, and one end of the second snap-fit ​​portion 210 may be rotatably connected to the groove wall of the relief groove 250.

[0050] When the second engaging portion 210 is rotated to the first state, a portion of the second engaging portion 210 protrudes from the relief groove 250 and can engage with the first engaging portion 310 at the upper limit of the decorative ring 300 in the axial direction. When the second engaging portion 210 is rotated to the second state, the second engaging portion 210 is located within the relief groove 250. This configuration ensures that when the first engaging portion 310 needs to be limited, a portion of the second engaging portion 210 protrudes from the relief groove 250 to limit the first engaging portion 310; when the first engaging portion 310 does not need to be limited, the second engaging portion 210 is located within the relief groove 250 and no longer limits the first engaging portion 310, allowing the first engaging portion 310 to disengage from the first limiting groove 220.

[0051] In other embodiments, the clearance groove 250 may not be provided on either the bracket 200 or the decorative ring 300.

[0052] In this embodiment, asFigure 14 , Figure 23 and Figure 24 As shown, the first snap-fit ​​part 310 is disposed on the decorative ring 300. The second snap-fit ​​part 210, the first limiting groove 220 and the clearance groove 250 can all be disposed on the bracket 200. Furthermore, one end of the second snap-fit ​​part 210 can be rotatably connected to the groove wall of the clearance groove 250 through the rotating shaft 212. The middle part of the second snap-fit ​​part 210 is rotatably connected to the groove wall of the clearance groove 250 through the elastic member described below. The electromagnetic member can be disposed on the inner wall of the bracket 200 and disposed opposite to the second snap-fit ​​part 210.

[0053] In this embodiment, when assembling the decorative ring 300, the decorative ring 300 is axially fastened to the bracket 200, causing the first snap-fit ​​portion 310 to be axially inserted into the first limiting groove 220. During the process of the first snap-fit ​​portion 310 being inserted into the first limiting groove 220, the second snap-fit ​​portion 210 is subjected to the force of the first snap-fit ​​portion 310, squeezing the elastic element and rotating towards the second state to avoid the first snap-fit ​​portion 310, so that the first snap-fit ​​portion 310 can be embedded into the first limiting groove 220. After the first snap-fit ​​portion 310 is embedded into the first limiting groove 220, the elastic element returns to its normal state and drives the second snap-fit ​​portion 210 to rotate to the first state. At this time, if... Figure 23 As shown, the first snap-fit ​​portion 310 is restricted by the groove wall of the first limiting groove 220 and the second snap-fit ​​portion 210, so that the decorative ring 300 is fixed on the bracket 200.

[0054] When the decorative ring 300 is damaged and needs after-sales repair and replacement, simply energize the electromagnetic component on the bracket 200, such as... Figure 24 As shown, the second snap-fit ​​part 210 is rotated to the second state and enters the clearance groove 250 by magnetic action, so that the second snap-fit ​​part 210 avoids the first snap-fit ​​part 310. Then, the decorative ring 300 can be removed by pulling it along the axial direction.

[0055] In optional embodiments, such as Figure 14 As shown, the decorative ring assembly may further include a locking drive member 700, which can be connected to the second latching portion 210. The locking drive member 700 can be used to drive the second latching portion 210 to switch to the first state. In this embodiment, the locking drive member 700 can actively provide force to the second latching portion 210, so that the second latching portion 210 is stably in the first state, thereby preventing the second latching portion 210 from easily switching from the first state to the second state.

[0056] Of course, the decorative ring assembly may also exclude the locking drive 700, and the second snap-fit ​​part 210 may remain in the first state under its own gravity.

[0057] Optionally, the locking drive 700 may include an elastic element, which can be connected to the second latching portion 210. With this configuration, the elastic element can automatically push the second latching portion 210 to the first state using its own elastic force and maintain it in the first state, achieving stable limiting of the first latching portion 310. This effectively prevents the second latching portion 210 from accidentally disengaging from the first state due to external vibrations, impacts, etc., thereby ensuring the stability of the connection between the decorative ring 300 and the bracket 200. Furthermore, compared to a telescopic drive, the locking drive 700 has a simpler structure and occupies less space. The elastic element maintains the state of the second latching portion 210 by continuously providing elastic force, requiring no additional energy and effectively reducing energy consumption.

[0058] Here, the elastic element can be a spring.

[0059] Of course, the locking drive 700 may not include the elastic element. For example, the locking drive 700 may include a telescopic drive, which is connected to the second latching part 210 and can drive the second latching part 210 to switch to the first state.

[0060] In an optional embodiment of this application, one of the bracket 200 and the decorative ring 300 may be provided with at least two first engaging portions 310, and the other may be provided with at least two second engaging portions 210 and a first limiting groove 220. Each first engaging portion 310 may be spaced apart circumferentially along the decorative ring 300, and at least a portion of each first engaging portion 310 may be respectively embedded in the corresponding first limiting groove 220. When each second engaging portion 210 is in a first state, each second engaging portion 210 is respectively limited and engaged with the corresponding first engaging portion 310 in the axial direction of the decorative ring 300. This arrangement allows the bracket 200 and the decorative ring 300 to form a multi-point connection, which effectively improves the connection stability and reliability between the bracket 200 and the decorative ring 300. Furthermore, it ensures that the bracket 200 and the decorative ring 300 are subjected to uniform stress, reducing local stress concentration and extending the service life of the bracket 200 and the decorative ring 300. For example, the decorative ring 300 may be provided with two first snap-fit ​​portions 310, and the bracket 200 may be provided with two second snap-fit ​​portions 210 and two first limiting grooves 220.

[0061] In other embodiments, one of the bracket 200 and the decorative ring 300 may be provided with only a first snap-fit ​​portion 310, and the other may be provided with only a second snap-fit ​​portion 210 and a first limiting groove 220.

[0062] In optional embodiments, such as Figure 2 , Figure 3 , Figure 14 , Figure 23 and Figure 24As shown, the decorative ring assembly may further include a sealing ring 500, which can be disposed between the decorative ring 300 and the housing 100. This arrangement can improve the sealing performance between the decorative ring 300 and the housing 100, and effectively prevent dust or liquids from entering the electronic device through the gap between the decorative ring 300 and the housing 100; furthermore, the sealing ring 500 can also act as a buffer when the electronic device is dropped or subjected to force, thereby protecting the decorative ring 300 and the lens 400 to a certain extent.

[0063] In other embodiments, the decorative ring assembly may also exclude the sealing ring 500.

[0064] In some embodiments, the sealing ring 500 can be a silicone ring or a rubber ring. This design allows the silicone or rubber ring to deform under pressure or vibration. When the decorative ring 300 is subjected to external impact or drop, the deformation of the sealing ring 500 can cushion the decorative ring 300 and protect it. Furthermore, compared to double-sided adhesive, silicone and rubber rings have superior waterproof performance, enabling the sealing ring 500 to maintain an effective seal under pressure or vibration, thus adapting to bumps and temperature changes during the daily use of electronic devices.

[0065] Optionally, such as Figure 18 As shown, the decorative ring 300 can be provided with a mounting groove 330, which can be set around the bracket 200, and a portion of the sealing ring 500 can be embedded in the mounting groove 330. This arrangement can effectively fix the sealing ring 500 and prevent it from shifting or falling off due to vibration, friction, or other factors during the use of the electronic device.

[0066] Of course, the decorative ring 300 may also be without the mounting slot 330.

[0067] The disassembly and assembly method provided in this application embodiment is simpler than the screw-locking solution. It saves the tedious steps of removing screws during disassembly and also simplifies the processing of the decorative ring 300, resulting in lower processing costs. Compared with the glue-dispensing solution, which cannot disassemble the decorative ring 300 separately and requires replacing the entire decorative ring assembly, the after-sales costs are lower.

[0068] Based on the decorative ring assembly provided in the embodiments of this application, the embodiments of this application also provide an electronic device, which may include a housing 100 and the decorative ring assembly described in any of the above embodiments, wherein the bracket 200 of the decorative ring assembly may be connected to the housing 100.

[0069] Alternatively, the electronic device can be a mobile phone, tablet, smartwatch, or other smart terminal.

[0070] The beneficial effects achieved by the electronic device provided in this application embodiment are consistent with the beneficial effects achieved by the decorative ring assembly provided in this application embodiment, and will not be repeated here.

[0071] In an optional embodiment, the housing 100 may include a battery cover, and the bracket 200 is provided with an annular protrusion 201. A clamping space is formed between the annular protrusion 201 and the decorative ring 300, and part of the battery cover is located in the clamping space to realize the connection between the battery cover, the bracket 200 and the decorative ring 300.

[0072] Optionally, an adhesive layer 600 is provided between the battery cover and the annular protrusion 201 to improve the connection strength and sealing of the battery cover and the bracket 200.

[0073] 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.
