[0029] It is easy to understand that according to the technical solution of the present disclosure, without changing the essential spirit of the present disclosure, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present disclosure, and should not be regarded as the entirety of the present disclosure or as a limitation or restriction to the technical solution of the present disclosure.

They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.

[0031] refer to Figures 1 to 5 ,in, Figure 1 A perspective view of an electronic device in an appearance network component area according to an embodiment of the present disclosure is shown; Figure 2 Shown based on Figure 1 Exploded diagram of

[0032] Figure 3 Shown based on Figure 1 Cross-sectional views to illustrate the paths of sound propagation; Figure 4 Shown based on Figure 1 A cross-sectional view for depicting the cooperation between the exterior mesh assembly and the middle frame; and Figure 5 A partial stereoscopic view of a middle frame according to an embodiment of the present disclosure is shown.

[0033] The electronic device includes an appearance mesh component 1 and a middle frame 2, the middle frame 2 includes a sound outlet 21 and a groove 22, the appearance mesh component 1 is arranged in the groove 22, the appearance mesh component 1 includes a first protrusion 11, and the first inner wall of the groove 22 is formed with a first limiting portion 221, and the first protrusion 11 abuts against the first limiting portion 221.

[0034] It should be understood that the appearance mesh component or appearance mesh can be understood as a component that presents a part of the appearance of an electronic device, or a component that can be seen by the user from outside the electronic device during the use of the electronic device. In addition, for electronic devices, it should also be broadly understood that various devices that can perform information transmission, signal processing and other operations through electronic technology can be covered, such as smart phones (including foldable phones), tablets, smart head-mounted devices (such as AR glasses, AR helmets), etc., as long as the device is used to make sound through the sound outlet, it can be applicable, and the appearance mesh component of the present disclosure can be used to achieve the expected industrial design appearance and performance. In this regard, the middle frame here can be broadly understood as a frame structure that accommodates these components. The sound outlet is used to transmit the sound from the speaker 3 of the electronic device to the outside world. For example, considering the structural characteristics of the sound outlet, the user can see the internal appearance mesh component from the outside of the electronic device through the sound outlet, and foreign substances from outside the electronic device, such as water, dust, etc., may invade the electronic device through the sound outlet. In some embodiments of the present disclosure, a smartphone is used as an example to explain the electronic device, and a speaker and a sound outlet disposed on the top of the smartphone are used as an example to explain the various technical solutions. However, the electronic device can include various types of smart terminals as described above. Figure 4 From the perspective of the embodiment, the first inner wall of the groove is the inner wall of the middle frame on the outside or on the right. Therefore, according to the technical solution, the self structure of the middle frame of the electronic device, that is, the first limiting part cooperates with the self structure of the appearance net component, that is, the first protruding part, to achieve the limitation of the appearance net component in a cost-effective manner without introducing additional limiting or positioning measures such as dispensing, and it is easy to disassemble and assemble, and easy to maintain.

[0035] Regarding the limiting design, in some embodiments of the present disclosure, the first limiting portion 221 forms a first enclosing structure, the first protrusion 11 abuts against the first enclosing structure on the outer side of the electronic device when viewed from the appearance net component 1 in the positive length direction X toward the sound outlet 21 and on the outer side of the electronic device when viewed from the appearance net component 1 in the positive thickness direction Z toward the display screen 7 of the electronic device, and the appearance net component 1 is at least partially arranged on the bottom of the groove 22.

[0036] This technical solution and the length and thickness directions mentioned therein can be clearly seen from, for example, Figure 4As can be seen in the figure, the direction along the arrow is positive, and the reverse direction is negative. Here, the first enclosure structure is formed by the section along the length direction and the section along the thickness direction of the first inner wall of the middle frame groove. In coordination with this, the first protrusion can be correspondingly constructed as a longitudinal beam with a square cross section so as to better match the shape of the first enclosure structure. For example, after the appearance net component is installed into the middle frame groove from top to bottom and the first protrusion is engaged with the first enclosure structure, the appearance net component can be prevented from moving in the disassembly direction opposite to the assembly direction, so that the appearance net component cannot be disengaged, and the assembly relationship between the appearance net component and the middle frame groove is maintained. In addition, the technical solution also involves that the appearance net component is at least partially arranged at the bottom of the groove of the middle frame groove, for example, the bracket and the pad to be explained below are arranged at the bottom of the groove, and the appearance net and the appearance net glue are arranged on the right side of the bracket and are spaced from the bottom of the groove. This design scheme improves the assembly stability of the appearance net component or the bracket and the pad with the middle frame groove, which will be further explained below.

[0037] Similarly, the appearance net assembly 1 also includes a second protrusion 16, and the groove 22 also includes a second limiting portion 222 formed by its first inner wall and the groove bottom, the second protrusion 16 abuts against the second limiting portion 222, and the second limiting portion 222 forms a second enclosing structure, and the second protrusion 16 abuts against the second enclosing structure on the outer side of the electronic device when viewed from the appearance net assembly 1 in the positive length direction X toward the sound outlet 21 and on the outer side of the electronic device when viewed from the display screen 7 of the electronic device toward the negative thickness direction -Z of the appearance net assembly 1.

[0038] Here, the second protrusion can be constructed similarly to the first protrusion, for example, it can be constructed as a longitudinal beam with a square cross section, and the two can be arranged in parallel. Thus, the right side of the second protrusion abuts against the vertical section of the first inner wall of the groove, and the lower side of the second protrusion abuts against the bottom of the groove, so as to limit the position of the appearance net component in two directions, for example, it plays a role in limiting the installation position of the appearance net component during the assembly process, and achieves a good position limiting effect together with the aforementioned first protrusion and the first enclosure structure.

[0039] Combination Figure 6 , which shows a top view of an electronic device in a waterproof and dustproof area according to an embodiment of the present disclosure.

[0040] As mentioned above, in order to deal with the situation where foreign substances from outside the electronic device may invade the electronic device through the sound outlet, for example, for waterproofing and dustproofing, in some embodiments of the present disclosure, the electronic device also includes a speaker 3, a speaker waterproof glue 4, a dustproof net 5, a screen waterproof glue 6 and a display screen 7, the speaker waterproof glue 4 is attached between the middle frame 2 and the speaker 3, the dustproof net 5 is arranged on the middle frame 2, and the screen waterproof glue 6 is attached between the middle frame 2 and the display screen 7.

[0041] It can be seen that the speaker waterproof glue and the screen waterproof glue are used together for waterproofing. Specifically, the water coming in from outside the electronic device is intercepted on the outside by the middle frame, display screen, screen waterproof glue, speaker waterproof glue, and the line of defense formed by the speaker; the dustproof net is used for dustproofing. Specifically, particles, especially fine particles, are intercepted on the outside by the line of defense formed by the middle frame, display screen, screen waterproof glue, and dustproof net. Correspondingly, the middle frame can be constructed with a receiving portion to accommodate the dustproof net, and a supporting portion for the arrangement of the speaker waterproof glue and the screen waterproof glue. It can also be understood that the appearance net assembly or the appearance net to be introduced below has the characteristics of a mesh cloth, so it can also play a certain dustproof effect, especially larger particles can be intercepted by the mesh cloth, so it can be regarded as a coarse filtration, and the dustproof net is a fine filtration measure. Therefore, the appearance net assembly can meet the IP6X (Ingress Protection 6X) dustproof requirements in conjunction with the dustproof net. Therefore, in this example, the appearance net component mainly plays the appearance function of meeting industrial design or user needs, as well as the coarse filtering function for larger particles, while the waterproof and dustproof function is mainly achieved by the above technical solution, thereby reducing the functional role of the appearance net component here by moving the waterproof and dustproof circuit inward, achieving the requirements of the appearance industrial design, and the appearance effect and external intrusion protection ability are stronger. At the same time, the reliability is higher when cleaning during the later use of the product, and the difficulty of achieving the IPX8 waterproof level is not increased. Since the design of waterproof and dustproof itself is not the focus of this disclosure, it will not be elaborated.

[0042] refer to Figures 7 to 10 ,in, Figure 7 A perspective view of a bracket viewed from the inside out according to an embodiment of the present disclosure is shown; Figure 8 A perspective view of a bracket viewed from outside to inside according to an embodiment of the present disclosure is shown; Fig. 9 A perspective view showing a cushion block according to an embodiment of the present disclosure viewed from the outside to the inside is shown; and Fig.10 A diagram showing the assembly relationship of a bracket and a cushion block according to an embodiment of the present disclosure is shown.

[0043] The appearance net assembly 1 includes a bracket 12 and a cushion block 13 . The first protrusion 11 and the second protrusion 16 are configured on a first side of the bracket 12 . The first side of the cushion block 13 abuts against the second side of the bracket 12 .

[0044] Based on this, the present application has carried out a disassembled structural design for the appearance net assembly, wherein the first protrusion and the second protrusion are constructed on the bracket, specifically on one side of the positive length direction X of the bracket (with Figure 4 The viewing angle is the right side), and the pad abuts against the other side (left side) of the bracket. Thus, the bracket of the appearance net assembly is limited by the joint action of the pad, the middle frame groove and the first and second limiting parts, so that the bracket cannot fall out.

[0045] Furthermore, the second side (left side) of the cushion block 13 is matched with the second inner wall (left vertical side wall) of the groove 22 without clearance, that is, the cushion block and the middle frame groove are zero-matched. Therefore, in the assembled state, the second inner wall of the groove can support the cushion block, and at the same time, the cushion block also supports the bracket, so that the bracket can be stably engaged with the first limit part and the second limit part of the middle frame groove to form a self-locking; and the appearance net to be described below includes the appearance net glue and is contained and supported by the bracket, that is, the bracket also supports the appearance net. Through the above-mentioned cooperation, the appearance part of the appearance net assembly, such as the appearance net, can be stably supported. Therefore, compared with other competing products that use adhesive to stick a small area of ​​the appearance net, this solution has a bracket inside to support the appearance net, and the appearance net will not be pushed off when it is subjected to external force (for example, when the user uses a pin to poke the appearance net through the sound outlet hole).

[0046] Combination Fig.10 The bracket 12 includes a sound transmission hole 121 , and a sound transmission space SP is formed between the bracket 12 and the pad 13 , and the sound from the speaker 3 of the electronic device can be transmitted to the sound outlet hole 21 via the sound transmission space SP and the sound transmission hole 121 .

[0047] The design of the sound transmission hole and the sound transmission space can support the sound from the speaker to be transmitted to the outside world through the sound transmission space, the sound transmission hole, and the sound outlet hole of the middle frame. That is, the design of the appearance mesh component will not affect the original sound function of the speaker or electronic device. For this reason, it can be understood that the sound transmission space is connected to the sound cavity of the electronic device, and the sound cavity is connected to the dustproof net, for example. The sound generated by the speaker passes through the waterproof glue of the speaker and the internal space of the middle frame, passes through the dustproof net into the sound cavity, and then passes through the sound cavity into the sound transmission space.

[0048] Regarding the structure of the bracket and the pad and the way the two cooperate, combined with Figures 7 to 10The bracket 12 includes a bracket body 122 and a matching portion 123 extending from the bracket body 122 toward the cushion block 13, the matching portion 123 is constructed at both ends and the center of the longitudinal direction of the bracket body 122, the first protrusion 11 and the second protrusion 16 are constructed on the bracket body 122 or the side of the bracket body facing the sound outlet, and the sound transmission hole 121 is opened in the bracket body 122. Correspondingly, the cushion block 13 includes a cushion block body 131 and an abutment portion 132 extending from the cushion block body 131 toward the bracket 12, the abutment portion 132 is constructed at both ends and the center of the longitudinal direction of the cushion block body 131, and the abutment portion 132 interferes with the matching portion 123 to form the sound transmission space SP.

[0049] It should be understood that interference fit between parts means that when the parts are connected, they are designed with appropriate geometric shapes and sizes so that they have certain interference or contact during the assembly process, thereby achieving the purpose of fastening and fixing. Here, the abutment portions at both ends of the cushion block in the longitudinal direction surround the matching portions at both ends of the bracket in the longitudinal direction from the outside, and the abutment portions also abut against the two ends of the bracket in the longitudinal direction to provide a stable assembly.

[0050] In some embodiments, the disclosure has specially designed the matching mode between the cushion block and the bracket, wherein the abutting portion 132 located in the center includes a first inclined surface 1321, and the matching portion 123 located in the center includes a second inclined surface 1231, and the first inclined surface 1321 and the second inclined surface 1231 are in contact with each other. Figure 4 From the perspective of , the first inclined plane and the second inclined plane are inclined from top to bottom along the X direction. Therefore, through the surface matching between the two inclined planes, a pair of interaction forces can be generated on the pad and the bracket in the direction normal to the inclined plane. That is, the pad 13 can be subjected to the force from the bracket 12 toward the second inner wall and the bottom of the groove 22, and the bracket 12 can be subjected to the force from the pad 13 toward the first inner wall of the groove 22. Therefore, on the one hand, the pad stably matches and limits the bracket with the first and second limiting parts of the middle frame groove, and on the other hand, the pad and the second inner wall of the middle frame groove can also be stably abutted together, thereby ensuring the technical effect described above that the appearance net will not be pushed off when subjected to external forces. In addition, it can also be considered to alternatively or supplementarily make this inclined surface matching method on the abutting parts and matching parts located at both ends, which can also achieve the above-mentioned technical effects.

[0051] As briefly mentioned above, the appearance net assembly 1 also includes an appearance net 14 and an appearance net glue 15. The appearance net 14 is visible from outside the electronic device through the sound outlet 21. The appearance net 14 is bonded to the bracket 12 by the appearance net glue 15. The appearance net 14 and the appearance net glue 15 are integrally formed by die-cutting.

[0052] It is understandable that in order to support the sound from the speaker to the outside through the sound outlet, the appearance mesh adhesive (also called the appearance mesh back adhesive) can also be provided with a through opening, which is aligned with the sound transmission hole of the bracket on the one hand, and aligned with the sound outlet hole of the middle frame on the other hand, so as to achieve smooth sound transmission. However, due to the inherent characteristics of the mesh, the appearance net does not need to be additionally provided with a sound transmission hole. The appearance net and the appearance net adhesive can be accommodated in the accommodation space surrounded by the first protrusion and the second protrusion of the bracket together with the bracket body part, and the appearance net abuts against the first inner wall of the middle frame groove. Here, the appearance net is responsible for the appearance of the appearance net component to show the user through the sound outlet. In this example, the appearance net and the appearance net adhesive are also designed to be die-cut into an integrated form, which has the advantages of high production efficiency, low cost and high product performance. In addition, the advantages of gluing include rapid fixation, high bonding strength, wide application range, no mechanical force, environmental protection and harmlessness, etc. In other feasible schemes, other connection methods can also be used, such as shape matching of mechanical structure, threaded connection, welding, etc. The specific assembly steps will be described in detail below.

[0053] In addition, in some other embodiments, the pads can be made into die-cut PET (polyethylene terephthalate) blocks or Teflon blocks, and assembled using simple jigs to achieve the same technical effect. Among them, PET material has good mechanical properties, oil resistance, fat resistance, dilute acid resistance, dilute alkali resistance, resistance to most solvents, high and low temperature resistance and little effect on its mechanical properties, low gas and water vapor permeability, high transparency, non-toxic and odorless; while Teflon has good heat resistance, high chemical stability and corrosion resistance.

[0054] As mentioned above, the appearance mesh is used to meet user needs or industrial design appearance. Therefore, in some embodiments of the present disclosure, the appearance mesh 14 is made of resin, and the outer side of the appearance mesh 14 is constructed with a metal coating by physical vapor deposition to give the non-metallic appearance mesh a metallic texture, which can be regarded as a metalloid. Among them, resin has strong plasticity, strong decorativeness and durability; while the equipment for physical vapor deposition is simple, energy consumption is low, production efficiency is high, material quality uniformity is high, and the requirements for raw materials are low and easy to recycle. It can be seen that compared with similar competing products that use metal 3D appearance mesh bonding, the processing difficulty and assembly difficulty of the appearance mesh component are reduced. At the same time, the use of a metal-like appearance mesh can avoid the influence of the metal appearance mesh on the antenna, greatly reducing the difficulty of antenna debugging and improving the communication quality.

[0055] In combination with the structural design of the electronic device disclosed in the present invention, the assembly process of the electronic device, especially the appearance net component, is briefly described below. To this end, the pad also includes a pad handle 1322 extending outward from the pad body along the Z direction, and the second side of the bracket (the side facing the speaker, Figure 4 The left side is configured with a chamfer 124, which can be formed by the matching parts of the bracket at both ends of the longitudinal direction.

[0056] First, as mentioned above, the appearance net and the appearance net are glued together, formed by die cutting, and bonded to the bracket of the appearance net component as a component.

[0057] Second, the middle frame groove for arranging the exterior net component can be formed by mold injection molding or CNC (Computer Numerical Control) processing.

[0058] Third, place the bracket that has the exterior net glued to it vertically downward (with Figure 4 Insert it into the groove of the middle frame and put it at the bottom so that the bracket contacts the bottom of the groove.

[0059] Fourth, after the bracket is inserted into the middle frame groove, hold the pad handle and insert the pad into the gap between the bracket and the second inner wall of the middle frame groove by relying on or with the help of the chamfer of the bracket. At this time, use the pad to move the bracket to the right (with Figure 4 The bracket can be pushed by the first protrusion and the second protrusion to be inserted into the first limit part and the second limit part of the middle frame groove. Here, after the pad is inserted into the bottom of the groove, the first inclined surface and the second inclined surface form the mating surface of the pad and the bracket, and the two slightly interfere (for example, 0.03mm). At the same time, because the mating surface is inclined from top to bottom in the X direction, the pad is supported by the second inner wall and the bottom of the middle frame groove to the lower left, and correspondingly, the bracket is supported by the first inner wall of the middle frame groove to the upper right, forming a self-locking.

[0060] Fifth, after the cushion block is assembled in place, the cushion block handle can be torn off to complete the assembly.

[0061] Sixth, in the subsequent assembly process of the entire electronic device, the dustproof net is bonded, the display screen is glued, and the display screen, speakers and other components are assembled. Finally, the appearance net component can be visible from outside the electronic device through the sound outlet, and the IP68 waterproof and dustproof flagship electronic device product requirements of the appearance net can be met.

[0062] In combination with the structural design of electronic devices, especially the appearance net component, which optimizes the assembly process, it should be known that compared with other competing products that stick the appearance net and then apply glue for waterproofing, the present invention only adopts the form of disassembly and assembly, that is, it is different from conventional competing products in that it separates the appearance net, appearance net glue, bracket, pad and other structural parts, which achieves or exceeds the same effect, greatly reduces the production cost of the gluing process, and eliminates the product turnover time increased by the gluing and pressure holding process.

[0063] It should be understood that all of the above preferred embodiments are illustrative rather than restrictive, and that various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present disclosure should be within the legal protection scope of the present disclosure.
