[0030] The following will be described in detail Figures 1-9 An electronic device according to an embodiment of the present application is described.

[0031] As Figure 1As shown, in some embodiments of this application, an electronic device is proposed, comprising: a housing 120, a first decorative ring 130, a second decorative ring 140, and a bracket 150. The housing includes a through hole 121, and at least a portion of the first decorative ring is disposed circumferentially in the through hole 121. Figure 8 (The arrow at point C points to) and at least a portion of the first decorative ring 130 is located within the through hole. A bracket 150, at least a portion of which is located within the through hole 121, abuts against the first decorative ring 130. A second decorative ring 140 is stacked on the side of the first decorative ring 130 opposite to the bracket 150.

[0032] A through hole 121 is formed on the housing 120. A first decorative ring 130 is distributed circumferentially along the through hole 121. At least a portion of the first decorative ring 130 is snapped onto the outer surface of the housing 120, and at least a portion of the first decorative ring 130 extends into the through hole 121.

[0033] The second decorative ring 140 and the bracket 150 are located on opposite sides of the first decorative ring 130 in the thickness direction, and at least a portion of the bracket 150 is located within the through hole 121. The bracket 150 supports at least a portion of the first decorative ring 130 that extends into the through hole 121. The second decorative ring is disposed on the side of the first decorative ring 130 opposite to the bracket 150, so that the first decorative ring 130 can support the second decorative ring 140.

[0034] In this embodiment, the bracket 150 and a portion of the first decorative ring 130 extend into the through hole 121, so that the height of the decorative ring assembly protruding from the surface of the housing 120 is small, thus avoiding the effect of making the electronic device look bulky. In addition, by reducing the space occupied by the decorative ring structure on the outside of the housing 120, it is beneficial to improve the user's convenience in using the electronic device.

[0035] In this embodiment, the first decorative ring 130 adopts a "Z"-shaped assembly scheme, in which the snap-fit ​​portion 133 located outside the housing 120 and the support portion 135 located inside the housing 120 are stacked in a staggered manner. The support portion 135 is located below the housing 120. The first decorative ring 130, the second decorative ring 140 and the bracket 150 form a decorative ring assembly. The radial cross-sectional width of the decorative ring assembly is about 1 / 2 of that of the camera decorative ring assembly in the related art. The protrusion height of the decorative ring assembly is greatly reduced. The height of the part of the decorative ring assembly protruding from the housing 120 is less than 1 / 2 of that of the camera decorative ring assembly in the related art. In this embodiment, the decorative ring assembly not only occupies little space, but also meets the assembly and strength requirements.

[0036] In some embodiments, the first decorative ring 130 comprises a clamping portion 133, a supporting portion 135 and a connecting portion 134. The clamping portion 133 is clamped on the circumference of the through hole 121. The supporting portion 135 is located in the through hole 121 and abuts against the bracket 150. The connecting portion 134 connects the clamping portion 133 and the supporting portion 135.

[0037] The clamping portion 133 is clamped on the circumference of the through hole 121, so that the shell 120 can limit the clamping portion 133, which is conducive to improving the installation stability of the first decorative ring 130. The supporting portion 135 extends into the through hole 121, thereby reducing the height of the first decorative ring 130 extending out of the shell. The bracket 150 supports the supporting portion 135, so that the bracket 150 and the supporting portion 135 cooperate with each other to fix the first decorative ring 130. The clamping portion 133 and the supporting portion 135 are connected through the connecting portion 134, so as to avoid the relative position of the clamping portion 133 and the supporting portion 135 from changing.

[0038] In some embodiments of the present application, it can be understood that the clamping portion 133 is clamped on the outer surface of the shell 120.

[0039] In some embodiments, the end of the through hole 121 towards the first decorative ring 130 has a chamfer 122, and the connecting portion 134 has a first inclined surface 1341 which cooperates with the chamfer 122.

[0040] The through hole 121 is provided with the chamfer 122 which faces the first decorative ring 130. The side of the first decorative ring 130 facing the chamfer 122 is provided with the first inclined surface 1341. The shape of the chamfer 122 is adapted to the shape of the first inclined surface 1341, so as to avoid interference between the structure of the shell 120 and the first decorative ring 130.

[0041] In some embodiments, a first sealing member 161 is arranged between the chamfer 122 and the connecting portion 134, and the shell 120 and the connecting portion 134 are sealingly connected through the first sealing member 161.

[0042] The first sealing member 161 seals between the shell 120 and the connecting portion 134, so as to avoid external water and dust from entering the inside of the shell 120 through the shell 120 and the connecting portion 134.

[0043] The shape of the chamfer 122 is adapted to the shape of the first inclined surface 1341, so that the shell 120 and the connecting portion 134 can hold the first sealing member 161 more tightly, thereby being conducive to improving the sealing effect between the shell 120 and the connecting portion 134.

[0044] In combination with Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the first seal 161 optionally comprises at least one of the following: foam glue, foam, and hot melt glue.

[0045] The first seal 161 can adopt at least one of the following: foam glue, foam, or hot melt glue. The foam glue has a pre-fixing function, and the foam glue can prevent the overflow of glue between the support 150 and the shell 120.

[0046] The foam has better tolerance, which improves the convenience in the process of installing the electronic device.

[0047] Of course, according to the use scenario, hot melt glue can also be selected as the sealing component between the shell 120 and the connecting portion 134.

[0048] In some embodiments, the electronic device further comprises a second seal 162, a part of the second seal 162 is located between the second decorative ring 140 and the connecting portion 134, and another part of the second seal 162 is located between the second decorative ring 140 and the support portion 135.

[0049] The second seal 162 seals between the second decorative ring 140 and the first decorative ring 130, avoiding the entry of external water and dust into the interior of the electronic device through the space between the second decorative ring 140 and the first decorative ring 130.

[0050] A part of the second seal 162 is arranged between the second decorative ring 140 and the connecting portion 134, and the second seal 162 is also arranged between the second decorative ring 140 and the support portion 135, so that the second seal 162 has a large contact area with the first decorative ring 130 and a large contact area with the second decorative ring 140, thereby facilitating the improvement of the sealing effect of the second seal 162 on the space between the first decorative ring 130 and the second decorative ring 140.

[0051] In some embodiments, the support 150 comprises a support body 151 and a boss 152, the boss 152 is distributed along the circumference of the support body 151 (the arrow points at the middle C), and the boss 152 is used to abut against the support portion 135. Figure 8

[0052] The circumference of the support body 151 is provided with the boss 152, and the boss 152 is used to support the support portion 135.

[0053] In this embodiment, the first decorative ring 130 is sleeved on the support body 151, and the support portion 135 is placed on the boss 152, the boss 152 supports the support portion 135, and the support body 151 radially limits the support portion 135, which facilitates the improvement of the installation stability of the first decorative ring 130.

[0054] ​In some embodiments of the present application, the boss 152 is provided with a glue groove on one side of the first decorative ring 130, and the glue in the glue groove can be used to seal and connect the boss 152 and the first decorative ring 130.

[0055] In some embodiments, the bracket body 151 and the first decorative ring 130 jointly form a groove 170, and the second decorative ring 140 is arranged in the groove 170.

[0056] The bracket body 151 and the first decorative ring 130 jointly form a groove 170, and in the case that the second decorative ring 140 is installed in the groove 170, the first decorative ring 130 is used to support the second decorative ring 140, and the bracket body 151 and the first decorative ring 130 can limit the second decorative ring 140 in the radial direction to avoid the second decorative ring 140 from moving relative to the first decorative ring 130, thereby ensuring the installation stability of the second decorative ring 140.

[0057] In some embodiments, the connecting portion 134 has a second inclined surface 1342 on one side of the second decorative ring 140, and the second inclined surface 1342 is arranged opposite to the side of the bracket body 151, and the second inclined surface 1342, the supporting portion 135 and the side of the bracket body 151 jointly form the groove 170.

[0058] The connecting portion 134 has the second inclined surface 1342, which is inclined relative to the supporting portion 135, and the second inclined surface 1342 limits the radial outer side of the second decorative ring 140, and the bracket body 151 limits the radial inner side of the second decorative ring 140, thereby avoiding the second decorative ring 140 from moving relative to the first decorative ring 130 and the bracket 150.

[0059] In a possible embodiment, the connecting portion 134 is inclined into the through hole 121 relative to the clamping portion 133, thereby forming the first inclined surface 1341 and the second inclined surface 1342 on the connecting portion 134. This bending design makes the first decorative ring 130 form a spatial staggered layout, and realizes the function that a part of the first decorative ring 130 is built below the shell 120 and inside the through hole 121, thereby reducing the outward protruding amount of the decorative ring structure and improving the overall rigidity by building the support structure inside.

[0060] In some embodiments, the bending angle of the connecting portion 134 relative to the clamping portion 133 is α, and 40°≤α≤50°.

[0061] The bending angle of the connecting portion 134 relative to the clamping portion 133 is between 40° and 50°, and in this angle range, the shell 120 and the connecting portion 134 have good mechanical distribution, thereby improving the cooperation effect between the shell 120 and the connecting portion 134. It can be understood that the first inclined surface 1341 and the second inclined surface 1342 are parallel to each other.

[0062] In combination Figure 1 , Figure 2 and Figure 3 , in some embodiments, the electronic device further comprises: a lens 110, a third sealing member 163 and a fourth sealing member 164, the lens 110 is arranged in the second decorative ring 140, the third sealing member 163 is located between the support portion 135 and the support 150, and the fourth sealing member 164 is located between the lens 110 and the support 150 of the electronic device.

[0063] The third sealing member 163 seals the gap between the support portion 135 and the support 150, and the fourth sealing member 164 seals the gap between the lens 110 and the support 150. The four sealing members 161, 162, 163 and 164 form a three-dimensional protection network, which effectively improves the sealing effect of the electronic device.

[0064] As shown in Figure 6 , in some embodiments, the electronic device further comprises: a fifth sealing member 165, the fifth sealing member 165 is located between the first decorative ring 130 and the shell 120.

[0065] In this embodiment, the first decorative ring 130 can be matched with the support surface of the shell 120 in a plane, and the support surface of the shell 120 is sealed with the first decorative ring 130 through the fifth sealing member 165.

[0066] In this embodiment, the fifth sealing member 165 is located between the first decorative ring 130 and the outer surface of the shell 120.

[0067] In some embodiments, the fifth sealing member 165 comprises at least one of the following: hot melt adhesive and transparent adhesive.

[0068] The hot melt adhesive can form a uniform adhesive layer between the first support portion 133 and the shell 120, thereby improving the connection effect between the first support portion 133 and the shell 120.

[0069] The transparent adhesive has good light transmission and can be suitable for light-colored decorative ring design.

[0070] As shown in Figure 7 , in some embodiments, the first support portion 133 is provided with a glue overflow groove 136 on the side facing the shell 120, and at least part of the fifth sealing member 165 is located in the glue overflow groove 136.

[0071] The first supporting part 133 is formed with a glue overflow groove 136 on the side facing the shell 120, so that the fifth sealing part 165 is partially embedded in the glue overflow groove 136 to form mechanical interlocking with the first supporting part 133. This design improves the connection effect of the fifth sealing part 165 and the first supporting part 133.

[0072] In some embodiments, the electronic device further comprises an appearance decoration ring 131, which is stacked on the side of the first decoration ring 130 away from the shell 120.

[0073] The appearance decoration ring 131 is located outside the shell 120 and serves as a visual presentation function, and the first decoration ring 130 forms support and protection for the appearance decoration ring 131.

[0074] In some embodiments of the present application, the appearance decoration ring 131 is stacked on the clamping part 133.

[0075] In combination with Figure 1 , Figure 2 , Figure 4 and Figure 5 , in some embodiments, the first side of the clamping part 133 is away from the appearance decoration ring 131, the first side of the appearance decoration ring 131 faces the clamping part 133, and the distance between the first side of the clamping part 133 and the first side of the appearance decoration ring 131 is D, D≥0.12mm.

[0076] The distance between the first side of the clamping part 133 and the first side of the appearance decoration ring 131 usually needs to be greater than or equal to 0.12mm, so that the distance between the first side of the clamping part 133 and the first side of the appearance decoration ring 131 meets the machining allowance requirement of the numerical control machine tool.

[0077] In combination with Figure 1 , Figure 2 , Figure 4 and Figure 5 , in some embodiments, the appearance decoration ring 131 comprises a layer assembly 137, a composite carrier layer 138 and a hardened layer 139, the layer assembly 137 is attached to the side of the clamping part 133 away from the shell 120, the composite carrier layer 138 is located on the side of the layer assembly 137 away from the first supporting part 133, and the hardened layer 139 is located on the side of the composite carrier layer 138 away from the layer assembly 137. The composite carrier layer 138 and the hardened layer 139 can transmit light.

[0078] The layer assembly 137 is used to display patterns, the composite carrier layer 138 is a structural carrier and plays a role in protecting the layer assembly 137, and the hardened layer 139 realizes the function of hardening the surface layer to prevent scratches on the appearance decoration ring 131.

[0079] In some embodiments, optionally, the composite carrier layer 138 is a polymethyl methacrylate and polycarbonate composite board.

[0080] The composite carrier layer 138 is a composite board composed of PMMA (polymethyl methacrylate) and PC (polycarbonate). PMMA has high light transmittance and excellent weather resistance, and PC has good bending modulus and impact strength. The combination of the two can improve the performance of the composite carrier layer 138.

[0081] In combination with Figure 1 , Figure 2 , Figure 4 and Figure 5 , in some embodiments, optionally, the layer assembly 137 includes a cover bottom layer 1371, a coating layer 1372, and a texture layer 1373. The cover bottom layer 1371 is attached to the side of the card connecting portion 133 away from the shell 120. The coating layer 1372 is located on the side of the cover bottom layer 1371 away from the card connecting portion 133. The texture layer 1373 is located between the coating layer 1372 and the composite carrier layer 138.

[0082] The cover bottom layer 1371 supports the coating layer 1372. The texture layer 1373 has a decorative pattern. The coating layer 1372 enhances the color saturation of the texture layer 1373.

[0083] In some embodiments, optionally, the electronic device further includes a connecting glue 166. The connecting glue 166 is used to seal the gap between the shell 120, the first decorative ring 130, and the bracket 150.

[0084] The connecting glue 166 is arranged between the shell 120, the first decorative ring 130, and the bracket 150. The connecting glue 166 can position and fix the bracket 150, thereby fixing the bracket 150 in the through hole 121. The connecting glue 166 can further improve the sealing performance of the electronic device. After the connecting glue 166 solidifies, the bracket 150 is locked to the shell 120 by the locking member 167, thereby further improving the connection stability between the bracket 150 and the shell 120.

[0085] In combination with Figure 8 and Figure 9 , it can be understood that, in some embodiments of the present application, the electronic device further includes a clamping jaw 190. One end of the clamping jaw 190 is connected to the bracket 150, and the other end is connected to the side of the shell 120 away from the first decorative ring 130. The bracket 150 has a threaded hole. The clamping jaw 190 is fixedly connected in the threaded hole of the bracket 150 by the locking member 167. The locking member 167 can be a screw.

[0086] In some embodiments, optionally, the bracket 150 is a plastic bracket or a glass fiber bracket.

[0087] The support 150 can be made of plastic or glass fiber material. The plastic support has the advantages of light weight and low cost. The bending strength of the glass fiber support is high, and the weight of the glass fiber support is also light, so that the electronic device realizes the purpose of light weight.

[0088] In the embodiment of the present application, a double-layer plate decoration ring design scheme is proposed. The plate decoration ring includes a first decoration ring 130 and an appearance decoration ring 131. The plate decoration ring adopts a "Z" type assembly scheme, and the appearance layer and the reinforcing layer are stacked staggered. The reinforcing layer body is placed below the battery cover of the shell 120. Not only the occupied space is small (the radial cross-sectional width of the decoration ring assembly is about 1 / 2 of the camera decoration ring assembly in the related art, the protrusion height of the decoration ring assembly is greatly reduced, and the height of the protrusion of the decoration ring assembly on the battery cover is less than 1 / 2 of the camera decoration ring assembly in the related art), but also the assembly and strength requirements can be met. Compared with the hardware scheme in the related art, the double-layer plate decoration ring can make a variety of styles and styles, and the personalization, differentiation, delicacy and seniority can be greatly improved. Moreover, it has the advantages of light weight and low cost. The following five decoration ring structure design schemes are proposed around the "Z" type plate decoration ring:

[0089] Scheme one, the first decoration ring 130 and the 45-degree inclined surface of the cold carving glass (the part of the shell 120 used to cooperate with the first decoration ring 130) adopt foam glue + UV glue pouring.

[0090] Scheme two, the first decoration ring 130 and the 45-degree inclined surface of the cold carving glass adopt foam interference + UV glue pouring.

[0091] Scheme three, the first decoration ring 130 and the 45-degree inclined surface of the cold carving glass adopt hot melt glue + UV glue pouring.

[0092] Scheme four, the first decoration ring 130 and the platform surface of the cold carving glass adopt hot melt glue + UV glue pouring.

[0093] Scheme five, the first decoration ring 130 and the platform surface of the cold carving glass adopt transparent adhesive + UV glue pouring.

[0094] The theme of the five schemes is designed around the double-layer plate decoration ring. The printed pattern layer of the plate decoration ring can present colorful patterns through processes such as electroplating or NVCM (Nano-Imprint Vacuum Coating Manufacturing) on the battery cover film, and the printed layer of the plate decoration ring is transparent above, giving users a refreshing and light feeling. The plate decoration ring has the advantages of light weight, easy processing, and lower unit cost. The plate decoration ring can reduce the influence on the OIS (Optical Image Stabilization) camera by controlling the plating layer impedance, and is conducive to electrostatic shielding. The scheme designs a special "Z" type structure to stagger the layout of the appearance layer and the reinforcing layer, and the reinforcing layer is built-in below the glass, which greatly reduces the protruding amount of the decoration ring, not only occupies small space, but also meets the assembly requirements and improves the overall competitiveness.

[0095] The assembly process of the design scheme is as follows: first, place the decoration ring main body in the jig and point the first glue (the first glue is the third sealing piece 163, which is usually hot melt glue), then assemble the first decoration ring 130 to the decoration ring main body through the limiting ribs and point the second glue (the second glue is the fourth sealing piece 164, which is usually hot melt glue), then assemble the second decoration ring 140 to the decoration ring main body through the limiting ribs, then place the three assembled decoration ring assemblies in the pressure holding jig for pressure holding and waiting for the glue to solidify. After the glue between the three decoration rings is solidified, the decoration ring assembly is assembled with the shell 120 through the precise positioning jig and the glue (the glue here is the connecting glue 166, which is usually UV glue, i.e. ultraviolet light curing glue), then the glue is cured through the glue curing equipment. Then the pressure claw is assembled to the plastic main body through the limiting ribs, and the screw is locked, and finally the lens 110 is assembled to complete the assembly of the entire decoration ring assembly. The locking piece 167 includes the pressure claw and the screw.

[0096] The first sealing piece 161 is foam glue, which is used to prevent the UV glue from flowing out and overflowing before curing, and also can play a role in pre-fixing and bonding the first decoration ring 130, preventing the decoration ring from being scratched to a certain extent.

[0097] Figure 2As can be seen from the figure, there are mainly three external liquid inlet paths, and the liquid inlet paths are indicated by arrows. The liquid inlet path between the second decorative ring 140 and the first decorative ring 130 is designed to meet the requirement of complete sealing of the entire ring of glue for some structural space. In the case of insufficient local space, the external three liquid inlet paths can be completely sealed through the liquid inlet path between the lens 110 and the second decorative ring 140 and the liquid inlet path between the first decorative ring 130 and the shell 120, thereby achieving dustproof and waterproof.

[0098] The structure design of the Z-shaped plate decorative ring will be described in detail below.

[0099] The plate decorative ring can be designed in two ways.

[0100] The first way includes seven layers, which are a hardened layer 139, a composite carrier layer 138, a texture layer 1373, a coating layer 1372, a cover bottom layer 1371, and a first decorative ring 130 (the first decorative ring 130 can be a polycarbonate raw plate).

[0101] The seventh layer of the second way is the same as the first six layers of the first way, and can be a glass fiber plate. This scheme has higher strength, but the processing difficulty is higher than that of the polycarbonate raw plate, and the cost is slightly higher.

[0102] The display layer and the reinforcing layer of the present application are staggered in the form of a Z-shaped letter. The first layer of composite plate is mainly used for display appearance, and thin plate is preferentially used to greatly reduce the protrusion of the decorative ring. The second layer of reinforcing plate is processed into a Z-shaped letter by a computer numerical control machine tool. The dashed line to the cover bottom layer 1371 and the clamping part 133 is placed outside by UV glue / OCA (Optically Clear Adhesive, optically clear adhesive) glue, which plays a reinforcing and connecting role. The connecting part 134 and the supporting part 135 are assembled to the inside of the shell 120, which plays a role of assembly positioning and reinforcing the entire decorative ring. The connecting part 134 can be inclined at an angle of 45 degrees (the angle of 45 degrees has better mechanical distribution, and the processing tool is conventional). The connecting part 134 corresponds to the position of the shell 120 and the second decorative ring 140, which is designed by matching with parallel inclined surfaces.

[0103] It should be noted that the thickness D of the dashed line to the coating cover bottom in the external decorative diagram should meet the CNC processing allowance requirement, and D≥0.12mm in general.

[0104] The difference between the second scheme and the first scheme is that the auxiliary material for plugging the UV glue on the first decorative ring 130 is changed from foam glue to foam. The compressibility of the foam is better than that of the foam glue, and it has better tolerance, but it cannot play a pre-fixing role. The assembly process needs to design the jig for applying UV glue and the assembly jig of the decorative ring assembly and the shell 120 as a two-in-one (the two jigs of the first scheme can be designed separately).

[0105] The difference between scheme three and scheme one and scheme two is that the auxiliary material for blocking the UV glue on the first decorative ring 130 is changed to point hot melt glue. Compared with foam or foam glue, the glue has better tolerance, but the overflow glue width needs to be ensured, the outer diameter of the decorative ring usually needs to be larger, and the overflow glue needs to be wiped. The hot melt glue uses colorless and transparent hot melt glue.

[0106] The difference between scheme four and the previous three schemes is that the first decorative ring 130 and the supporting surface of the shell 120 adopt plane cooperation, and the shell 120 is fixed with the first decorative ring 130 through double-sided adhesive, and at the same time, the double-sided adhesive blocks the overflow glue before the UV glue solidifies. The platform surface cooperation design is beneficial to the overall assembly and tolerance, but the narrow seam glue solidification has higher requirements for the type and equipment of the glue.

[0107] Scheme five: the first decorative ring 130 and the supporting surface of the shell 120 adopt plane cooperation, and the plate decorative ring (processing an overflow groove 136) and the shell 120 are fixed through point gluing, and at the same time, the solidified hot melt glue blocks the overflow glue before the UV glue solidifies. The platform surface cooperation design is beneficial to the overall assembly and tolerance, but the narrow seam glue solidification has higher requirements for the type and equipment of the glue, and the decorative ring and the glass are difficult to disassemble due to the simultaneous solidification of UV glue and hot melt glue, which is not conducive to the maintenance and reuse of the decorative ring, but the overall strength and reliability are better.

[0108] In the embodiment of the present application, the thickness of the hardening layer 139 is 3-12 microns, the hardening layer 139 is hardened by processes such as shower coating, the thickness of the composite carrier layer 138 is 0.25 mm, and the thickness of the composite carrier layer 138 can be adjusted to other values. The thickness of the texture layer 1373 is 13 microns, the thickness of the plating layer 1372 is 300 nm, the thickness of the cover bottom layer 1371 is 0.025 mm, the thickness of the glue 168 is 0.016-0.02 mm, the thickness of the first decorative ring 130 is 1 mm, and the thickness of the first decorative ring 130 can be adjusted to other values.

[0109] The embodiment of the present application has the following effects:

[0110] 1. The novel plate decorative structure scheme of the present application can present a variety of patterns, and the appearance is clear and transparent, which is extremely personalized and different, and improves the overall competitiveness of the product.

[0111] 2. The present patent adopts a special "Z" type structure design, which arranges the appearance layer and the reinforcing layer staggered, and the reinforcing layer is built-in below the shell 120, which greatly reduces the protrusion of the decorative ring, occupies small space, meets the assembly requirements, and improves the overall competitiveness.

[0112] 3. Compared with the hardware decorative ring, the plate decorative ring is light in weight, effectively reduces the weight of the whole machine, and improves the user experience.

[0113] 4. Compared with the hardware decorative ring, the new plate decorative ring has the advantage of easy processing, and the unit price is lower.

[0114] 5. The plate decorative ring can reduce the influence on the OIS camera by controlling the plating impedance, and is conducive to electrostatic shielding.

[0115] The electronic device of the present application can be a mobile phone, a tablet computer, an electronic book or the like, and the electronic device can also be a high-end knob or a decorative part used in various household appliances, smart door locks, smart furniture and the like.
