[0002] With the development of communication technology, the functions of electronic devices are becoming more and more abundant, and users have higher and higher requirements on the quality of electronic devices. Among them, the decorative ring component is connected to the back cover, which has an important impact on the appearance and quality of the electronic device.

[0003] In the prior art, such as Figure 1 A partial cross-sectional schematic diagram of a decorative ring assembly is shown. The decorative ring assembly generally includes a decorative ring 20', a bracket 10', a first adhesive layer 30', a skirt member 40' and a second adhesive layer 50'. The decorative ring 20' is connected to the bracket 10', the bracket 10' is connected to the first adhesive layer 30', the first adhesive layer 30' is connected to the skirt member 40', and the second adhesive layer 50' covers the skirt member 40' for connecting to the back cover 80'. Part of the skirt member 40' extends to the back cover 80' of the electronic device to improve the sealing of the decorative ring assembly installed on the back cover 80', prevent dust and liquid from entering, and avoid interference between the part of the skirt member 40' and the electronic devices inside the electronic device.

[0004] However, when the inventor studied the prior art, he found that in the process of removing the back cover 80' from the skirt piece 40', the second adhesive layer 50' connected to the back cover 80' is likely to pull the skirt piece 40', causing the skirt piece 40' to separate from the first adhesive layer 30', and the first adhesive layer 30' is likely to be torn, so that the decorative ring assembly is damaged and cannot be reused, thereby increasing the maintenance cost after disassembly. Summary of the invention

[0005] In view of the above problems, the present invention is proposed to provide a decorative ring assembly and an electronic device that overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a decorative ring assembly for use in electronic equipment, characterized in that the decorative ring assembly comprises: a bracket, a decorative ring, a first adhesive layer, and a skirt piece;

[0008] The bracket includes a first support portion and a second support portion arranged outside the first support portion, the decorative ring is connected to the first support portion, and the second support portion includes a first side and a second side arranged in opposite directions;

[0009] The skirt member is connected to the first side of the second supporting portion through a first adhesive layer;

[0010] The skirt piece is provided with at least one extension portion, which bypasses the first adhesive layer and the edge of the second supporting portion and is connected to the second side of the second supporting portion.

[0011] In a second aspect, an embodiment of the present application provides an electronic device, wherein the electronic device includes the decorative ring assembly.

[0012] In an embodiment of the present application, the decorative ring assembly includes: a bracket, a decorative ring, a first adhesive layer and a skirt member; the bracket includes a first support portion and a second support portion arranged outside the first support portion, the decorative ring is connected to the first support portion, and the second support portion includes a first side and a second side that are arranged away from each other; the skirt member is connected to the first side of the second support portion through the first adhesive layer; the skirt member is provided with at least one extension portion, the extension portion bypasses the first adhesive layer and the edge of the first support portion, and is connected to the second side of the second support portion. By providing multiple extension portions on the skirt member, the extension portion bypasses the first adhesive layer and the edge of the second support portion of the bracket and extends to the second side of the bracket, so that the extension portion stably fixes the first adhesive layer to the second side of the second support portion, thereby enhancing the bonding strength between the first adhesive layer and the skirt member. In this way, in the process of removing the back cover of the electronic device, due to the enhanced bonding strength between the skirt member and the first adhesive layer, the second adhesive layer connected to the back cover is not easy to generate a large pull on the skirt member, so that the skirt member is separated from the first adhesive layer. It also prevents the first adhesive layer from being torn, making the decorative ring less susceptible to damage and capable of being reused, thereby reducing the cost of repairs after disassembly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference Figures 2 to 9 , shows a schematic structural diagram of a decorative ring assembly applied to an electronic device according to an embodiment of the present application, which may specifically include: a bracket 10, a decorative ring 20, a first adhesive layer 30 and a skirt member 40;

[0031] The bracket 10 includes a first support portion 11 and a second support portion 12 disposed outside the first support portion 11. The decorative ring 20 is connected to the first support portion 11. The second support portion 12 includes a first side 121 and a second side 122 disposed in opposite directions.

[0032] The skirt member 40 is connected to the first side 121 of the second support portion 12 through the first adhesive layer 30;

[0033] At least one extension portion 41 is disposed on the skirt member 40 . The extension portion 41 bypasses the first adhesive layer 30 and the edge of the second support portion 12 and is connected to the second side 122 of the second support portion 12 .

[0034] In the embodiment of the present application, by providing a plurality of extensions 41 on the skirt member 40, the extensions 41 are bypassed around the first adhesive layer 30 and the edge of the second support portion 12 of the bracket 10, and extended to the second side 122 of the bracket 10, so that the extensions 41 fix the first adhesive layer 30, thereby enhancing the bonding strength between the skirt member 40 and the first adhesive portion, and the two are not easily separated. In this way, in the process of disassembling the back cover 80 of the electronic device, due to the enhanced connection strength between the skirt member 40 and the first adhesive layer 30, the second adhesive layer 50 connected to the back cover 80 is not easy to pull the skirt member 40 to separate the skirt member 40 from the first adhesive layer 30. It also avoids the first adhesive layer 30 from being torn, so that the decorative ring 20 is not easily damaged and can be reused, reducing the maintenance cost after disassembly.

[0035] For example, the number of extensions 41 can be 2, 3, 6, 8, etc., and the embodiment of the present application may not limit the specific number of extensions 41. The shape of the extension 41 may include a rectangle, a square, a trapezoid, etc., and the embodiment of the present application may not limit the specific shape of the extension 41.

[0036] Specifically, in the embodiment of the present application, the bonding strength of the first adhesive layer 30 can be the same as the bonding strength of the second adhesive layer 50. Due to the reinforcement effect of the extension 41 of the skirt member 40 on the first adhesive layer 30, when the second adhesive layer 50 is separated from the skirt member 40, it is not easy to pull the skirt member 40 and the first adhesive layer 30 apart. There is no need to adopt a solution of strong and weak adhesive layers, for example, setting the bonding strength of the first adhesive layer 30 to be greater than the bonding strength of the second adhesive layer 50. It is avoided that the back cover 80 of the electronic device is easily separated from the decorative ring assembly due to the weak bonding strength of the second adhesive layer 50, reducing the connection reliability of the back cover 80 and the decorative ring assembly, and reducing the risk of liquid and dust entering the decorative ring assembly. In addition, the solution of strong and weak adhesive layers still has the problem that at least one of the first adhesive layer 30 and the second adhesive layer 50 is easily torn and damaged during the disassembly process. In addition, the solution of strong and weak adhesive layers will also increase the thickness of the entire electronic device and increase the stacking thickness of the entire device.

[0037] It should be noted that the bonding strength of the first bonding layer 30 may be different from the bonding strength of the second bonding layer 50. For example, the bonding strength of the first bonding layer 30 is greater than the bonding strength of the second bonding layer 50, or the bonding strength of the first bonding layer 30 is less than the bonding strength of the second bonding layer 50. This embodiment of the present application is not limited to this.

[0038] For example, the material of the first adhesive layer 30 may include any one of oily glue, strong adhesive, and hot melt adhesive, which can well realize the reliable connection between the skirt piece 40 and its bracket 10. The material of the second adhesive layer 50 may also include any one of oily glue, strong adhesive, and hot melt adhesive, which can well realize the reliable connection between the skirt piece 40 and the back cover 80 of the electronic device. The specific materials of the first adhesive layer 30 and the second adhesive layer 50 are not limited in this application.

[0039] Specifically, in the embodiment of the present application, the material of the skirt member 40 includes one of polyethylene terephthalate and polyethylene naphthalate. The above material has good creep resistance, fatigue resistance, friction resistance, and dimensional stability, and can achieve reliability and sealing of the decorative ring assembly installed in the electronic device with a relatively thin thickness, thereby extending the service life of the decorative ring assembly.

[0040] Among them, polyethylene terephthalate, also known as PET (Poly ethylene Terephthalae), is widely used in daily production and is easy to obtain. It has excellent physical and mechanical properties, good creep resistance, fatigue resistance, friction resistance, and dimensional stability. Polyethylene naphthalate, also known as PEN (Polyethylene naphthalene-2,6-dicarboxylate), has good processing performance, fast molding cycle, and good wear resistance.

[0041] Specifically, in the embodiment of the present application, the decorative ring assembly further includes a third adhesive layer 70, and the third adhesive layer 70 is connected between the bracket 10 and the decorative ring 20 to fix the bracket 10 and the decorative ring 20 and enhance the connection strength between the two.

[0042] Optionally, in the embodiment of the present application, there are multiple extensions 41, and the multiple extensions 41 are spaced apart on the periphery of the skirt member 40. In this way, the skirt member 40 and the first adhesive layer 30 can be reinforced at multiple locations on the periphery of the skirt member 40, further improving the connection strength between the skirt member 40 and the first adhesive layer 30, so that the two are not easily separated during the disassembly process.

[0043] Specifically, in practical applications, the specific position of the extension portion 41 may be set as needed, and the embodiment of the present application may not limit the specific setting position of the extension portion 41.

[0044] In some optional embodiments of the present application, multiple extensions 41 are symmetrically distributed relative to the center of the skirt member 40. In this way, the skirt member 40 can be reinforced with the first adhesive layer 30 at symmetrical positions, so that when the skirt member 40 is subjected to tearing force, the extensions 41 are subjected to a more uniform force, have a better connection strength, and enhance the reinforcement effect between the skirt member 40 and the first adhesive layer 30. Specifically, the multiple extensions 41 can be axially symmetrically distributed or centrally symmetrically distributed relative to the center of the skirt member 40, and the embodiments of the present application are not limited to this.

[0045] In the embodiment of the present application, optionally, the second support portion 12 of the bracket 10 is provided with a relief portion 13 for evading the electronic device, and the first adhesive layer 30 is at least partially exposed in the relief portion 13. The skirt member 40 is provided with a connecting portion 42 at a position opposite to the relief portion 13, and the connecting portion 42 is at least partially embedded in the relief portion 13. In this way, the connecting portion 42 can seal the relief portion 13, thereby improving the sealing performance of the decorative ring assembly.

[0046] In practical applications, in order to avoid some electronic components in the electronic device, such as battery cells and other high components, the second support portion 12 of the bracket 10 is provided with an escape portion 13. Correspondingly, the skirt member 40 is provided with a connecting portion 42 relative to the escape portion 13, and the connecting portion 42 is at least partially embedded in the escape portion 13 to achieve sealing of the second support portion 12 and avoid risks such as liquid and dust intrusion into the decorative ring assembly.

[0047] Specifically, the position of the skirt member 40 opposite to the escape portion 13 refers to the same or similar position of the skirt member 40 and the escape portion 13 in the vertical direction. Specifically, the shape and size of the connecting portion 42 are also the same or similar to the shape and size of the escape portion 13.

[0048] Optionally, in the embodiment of the present application, the first adhesive layer 30 includes a third side 31 and a fourth side 32 that are arranged in opposite directions, the third side 31 is connected to the skirt member 40, and at least part of the surface of the fourth side 32 is exposed to the avoidance portion 13. The skirt member 40 is also provided with a shielding portion 43, which bypasses the edge of the first adhesive layer 30, is connected to the fourth side 32 of the first adhesive layer 30, and shields the portion of the first adhesive layer 30 exposed to the avoidance portion 13. In this way, the exposed portion of the first adhesive layer 30 is prevented from being easily exposed to dust, and the first adhesive layer 30 is prevented from being stained with other components during the disassembly of the electronic device. In addition, there is no need to set up other independent shielding portion 43 structures for shielding the exposed first adhesive layer 30, thereby reducing the structural complexity of the decorative ring assembly.

[0049] In the embodiments of the present application, specifically, Figure 4As shown, the first adhesive layer 30 is matched with the skirt member 40, and the shapes and sizes of the two are the same or similar. The first adhesive layer 30 overlaps with the other parts of the skirt member 40 except the extension part 41 and the shielding part 43, so as to bond the skirt member 40 to the bracket 10. Since the second support part 12 of the bracket 10 is provided with the avoidance part 13, the fourth side 32 of the part where the first adhesive layer 30 overlaps with the connecting part 42 is exposed to the second support part 12. By bypassing the shielding part 43 around the edge of the first adhesive layer 30 and connecting to the fourth side 32 of the first adhesive layer 30, the fourth side 32 of the part where the first adhesive layer 30 overlaps with the connecting part 42 is exposed to the second support part 12 and shielded. This prevents the exposed part from being exposed to dust and from being stained by other components during the disassembly process of the electronic device.

[0050] Specifically, in the embodiment of the present application, the shielding portion 43 and the skirt piece 40 are an integrally formed structure, which facilitates the processing and manufacturing of the skirt piece 40 and the shielding portion 43 and also reduces material loss and manufacturing processes.

[0051] In the embodiment of the present application, optionally, the size of the shielding portion 43 is greater than or equal to the size of the avoidance portion 13. In this way, the shielding portion 43 can completely cover the avoidance portion 13, thereby improving the sealing performance and anti-sticking performance of the skirt member 40 to the bracket 10.

[0052] In some optional embodiments of the present application, the first adhesive layer 30 includes a third side 31 and a fourth side 32 that are arranged in opposite directions, the third side 31 is connected to the skirt member 40, and at least a portion of the surface of the fourth side 32 is exposed to the avoidance portion 13. The decorative ring assembly also includes a release layer 60, which is bonded to the first side 121 of the second support portion 12 through the first adhesive layer 30 to cover the portion of the first adhesive layer 30 exposed to the avoidance portion 13. At least a portion of the extension portion 41 bypasses the first adhesive layer 30, the release layer 60 and the edge of the second support portion 12, and is connected to the second side 122 of the second support portion 12.

[0053] In the embodiments of the present application, specifically, Figure 5 As shown, the first adhesive layer 30 is matched with the skirt member 40, and the shapes and sizes of the two are the same or similar. The first adhesive layer 30 overlaps with the other parts of the skirt member 40 except the extension part 41, so as to bond the skirt member 40 to the bracket 10. Since the second support part 12 of the bracket 10 is provided with the avoidance part 13, the fourth side 32 of the overlapping part of the first adhesive layer 30 and the connecting part 42 is exposed to the second support part 12. The anti-adhesion property of the exposed part of the first adhesive part is realized by providing an independent anti-adhesion layer 60, so as to prevent the exposed part of the first adhesive layer 30 from being easily exposed to dust, and the first adhesive layer 30 from being stained with other parts during the disassembly process of the electronic device.

[0054] At the same time, at least part of the extension portion 41 of the skirt piece 40 can bypass the first adhesive layer 30, the anti-sticking layer 60 and the edge of the second support portion 12, and be connected to the second side 122 of the second support portion 12, thereby wrapping and reinforcing both the first adhesive layer 30 and the anti-sticking layer 60, thereby enhancing the connection strength between the skirt piece 40 and the first adhesive layer 30 and the anti-sticking layer 60, and preventing the skirt piece 40 from being separated from the first adhesive layer 30 due to tearing force.

[0055] Specifically, in the embodiment of the present application, the material of the anti-adhesive layer 60 may be the same as or different from the material of the skirt member 40. For example, the anti-adhesive member 60 may also be made of PET or PEN material, which is not limited in the embodiment of the present application.

[0056] The embodiment of the present application also provides an electronic device, the electronic device comprising the decorative ring assembly. The decorative ring assembly can prevent the decorative ring assembly from being easily damaged and unable to be reused during the disassembly process of the electronic device, thereby greatly reducing the cost of disassembly and maintenance.

[0057] In the embodiment of the present application, specifically, the electronic device may include but is not limited to any one of a mobile phone, a tablet computer and a wearable device, and the embodiment of the present application may not limit the specific type of the electronic device.

[0058] Specifically, in the embodiment of the present application, the electronic device further includes a back cover 80, the decorative ring assembly includes a second adhesive layer 50, the back cover 80 is connected to the second adhesive layer 50, and the second adhesive layer 50 is arranged close to the back cover 80. Specifically, the second adhesive layer 50 can be connected to the side of the skirt member 40 away from the first adhesive layer 30. In this way, the back cover 80 is more firmly connected to the decorative ring assembly through the second adhesive layer 50.

[0059] In summary, the decorative ring assembly described in the embodiment of the present application can at least include the following advantages:

[0060] In an embodiment of the present application, the decorative ring assembly includes: a bracket, a decorative ring, a first adhesive layer and a skirt member; the bracket includes a first support portion and a second support portion arranged outside the first support portion, the decorative ring is connected to the first support portion, and the second support portion includes a first side and a second side that are arranged away from each other; the skirt member is connected to the first side of the second support portion through the first adhesive layer; the skirt member is provided with at least one extension portion, the extension portion bypasses the first adhesive layer and the edge of the first support portion, and is connected to the second side of the second support portion. By providing multiple extension portions on the skirt member, the extension portion bypasses the first adhesive layer and the edge of the second support portion of the bracket and extends to the second side of the bracket, so that the extension portion fixes the adhesive layer to the second side of the second support portion. In this way, in the process of removing the back cover of the electronic device, due to the enhanced bonding strength between the skirt member and the first adhesive layer, the second adhesive layer connected to the back cover is not easy to produce a large pull on the skirt member, so that the skirt member is separated from the first adhesive layer. It also prevents the first adhesive layer from being torn, making the decorative ring less susceptible to damage and capable of being reused, thereby reducing the cost of repairs after disassembly.

[0061] In summary, the electronic device described in the embodiments of the present application may at least have the following advantages:

[0062] In an embodiment of the present application, the electronic device includes the decorative ring assembly. The decorative ring assembly includes: a bracket, a decorative ring, a first adhesive layer and a skirt member; the bracket includes a first support portion and a second support portion arranged outside the first support portion, the decorative ring is connected to the first support portion, and the second support portion includes a first side and a second side that are arranged away from each other; the skirt member is connected to the first side of the second support portion through the first adhesive layer; the skirt member is provided with at least one extension portion, the extension portion bypasses the first adhesive layer and the edge of the first support portion, and is connected to the second side of the second support portion. By providing a plurality of extension portions on the skirt member, the extension portion bypasses the first adhesive layer and the edge of the second support portion of the bracket, and extends to the second side of the bracket, so that the extension portion fixes the adhesive layer to the second side of the second support portion. In this way, in the process of removing the back cover of the electronic device, due to the enhanced connection strength between the skirt member and the first adhesive layer, the second adhesive layer connected to the back cover is not easy to produce a large pull on the skirt member, so that the skirt member is separated from the first adhesive layer. It also prevents the first adhesive layer from being torn, making the decorative ring less susceptible to damage and capable of being reused, thereby reducing the cost of repairs after disassembly.
