Technical Field

[0002] The embodiments of the present application relate to the field of terminals, and in particular to an electronic device. Background Art

[0003] With the continuous development of electronic device form factors and technologies, ultra-thin designs have become a trend. Existing electronic devices have external protective covers for their displays and flexible circuit boards (COFs). These covers are located outside the display, are relatively thick, and protrude from the display, making the overall structure less compact and impacting the user experience. Summary of the Invention

[0004] An embodiment of the present application provides an electronic device that can effectively reduce the thickness of a display screen assembly through structural optimization.

[0005] The first aspect of the embodiment of the present application provides an electronic device, which includes a display screen assembly and a protective assembly. The protective assembly is arranged along the side edge of the display screen assembly and includes a decorative layer, a bracket and a buffer layer; wherein the bracket is located beside the display screen assembly and is fixed to the side edge of the display screen assembly; the decorative layer is located on the outside of the display screen assembly and the bracket, the first part of the decorative layer is bonded to the first surface of the bracket through a first adhesive layer, and the second part of the decorative layer is against the screen surface through a buffer layer. The first surface is a surface on the bracket that is located beside the screen surface of the display screen assembly, and the first surface does not occupy the assembly space of the screen surface. After assembly, the bracket is located on the inner side of the decorative layer, and the decorative layer fixed to the outside of the bracket is used as a structure to press against the display screen, and the product outline is formed by the decorative layer. By reasonably controlling the thickness of the decorative layer and the buffer layer, the thickness of the protective assembly can be effectively reduced, which is in line with the design trend of thin and light electronic devices.

[0006] In practical applications, based on the split design in which the decorative layer is independent of the bracket, the decorative layer can be made of a material different from that of the bracket, such as but not limited to a metal material with good rigidity, to further reduce the thickness of the protective component.

[0007] Exemplarily, the first surface of the bracket may not protrude from the screen surface of the display screen assembly, so as to avoid occupying the space outside the display screen in the thickness direction, thereby facilitating reducing the thickness of the protective assembly.

[0008] Based on the first aspect, the present application also provides a first implementation of the first aspect: the electronic device further includes a speaker located inside the protective assembly; a retaining opening corresponding to the speaker's horn is provided on the bracket and the first adhesive layer, respectively, to establish a sound channel; and a speaker mesh structure is configured on at least the area of ​​the decorative layer corresponding to the retaining opening, which also functions as a speaker. In other words, the speaker mesh functions as a pressure against the display screen, effectively reducing the thickness while allowing users to perceive the front-firing sound, further enhancing the user experience.

[0009] Based on the first embodiment of the first aspect, the present application also provides a second embodiment of the first aspect: the speaker mesh structure is configured over the entire area of ​​the decorative layer. This arrangement allows the user to perceive the sound coming from the front while the bracket is hidden inside the visible, complete speaker mesh surface, providing a better visual experience. This embodiment has the characteristics of a simple and practical structure.

[0010] Based on the second embodiment of the first aspect, the embodiment of the present application also provides a third embodiment of the first aspect: the inner surface of the speaker mesh structure is bonded with a shielding mesh through a second adhesive layer. Thus, compared with the avoidance opening position, the shielding mesh covering the inner surface of the speaker mesh can ensure that there is no visible color difference on its outside.

[0011] For example, the shielding net can be made of mesh fabric or non-woven fabric, which is conducive to controlling the thickness and has low manufacturing and assembly costs.

[0012] Based on the third embodiment of the first aspect, the present application also provides a fourth embodiment of the first aspect: the second adhesive layer is a water-based adhesive layer. In this way, the water-based adhesive not only penetrates the mesh bonding surface of the shielding net, but also the mesh side surfaces. This not only meets the requirements for reliable bonding and fixing of the shielding net to the speaker mesh, but also maintains the sound permeability of the speaker.

[0013] In practical applications, the second adhesive layer can be formed by dipping the shielding net into water-based adhesive, which has good processability and can fully utilize the characteristics of the water-based adhesive.

[0014] Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, the embodiment of the present application also provides a fifth embodiment of the first aspect: the first adhesive layer is a hot melt adhesive layer, which has reliable bonding and controllable costs; in addition, based on the good affinity between hot melt adhesive and water-based adhesive, the overall assembly reliability of the protective component can be improved.

[0015] Based on the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, the embodiment of the present application further provides a sixth embodiment of the first aspect: the first adhesive layer includes an extension portion, which extends toward the buffer layer and extends out of the extension portion of the bracket, the second portion of the decorative layer is abutted against the screen surface through the first end side of the buffer layer, and the second end side of the buffer layer is overlapped and bonded with the extension portion of the first adhesive layer, wherein the first end side and the second end side are arranged relative to each other. In this arrangement, by forming an overlapping bonding area between the buffer layer and the first adhesive layer, a light-shielding barrier is constructed between the buffer layer and the bracket structure, which can completely avoid the possibility of light transmission between the two. On the basis of the protective component being integrated with a speaker function, the display screen component can maintain good display performance.

[0016] In practical applications, the second end side of the buffer layer can be located inside the protruding portion of the first adhesive layer, or the second end side of the buffer layer can also be located outside the protruding portion of the first adhesive layer, both of which can form a light-shielding barrier through a reliable bonding relationship.

[0017] For example, the first end side of the buffer layer can be retracted into the decorative layer, ensuring a reliable pressing relationship while having a good appearance.

[0018] Exemplarily, the buffer layer may be a sponge strip, which facilitates controlling the thickness.

[0019] Based on the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, or the sixth embodiment of the first aspect, the embodiment of the present application also provides a seventh embodiment of the first aspect: the display screen assembly includes a liquid crystal display screen, the liquid crystal display screen includes a display screen circuit COF, and the side of the bracket near the liquid crystal display screen has an avoidance space to form an installation avoidance space for the display screen circuit COF to avoid affecting the pin connection between the circuit COF and the display screen assembly, and a shielding sheet is bonded and fixed to the first adhesive layer opposite to the avoidance space to prevent the bent circuit COF from being bonded to the first adhesive layer by removing the material portion, thereby ensuring a reliable connection relationship of the pins.

[0020] Exemplarily, the shielding sheet is made of Mylar.

[0021] Based on the seventh embodiment of the first aspect, the present application also provides an eighth embodiment of the first aspect: the shielding sheet extends from the first adhesive layer to the second surface, which is the surface of the bracket opposite the display circuit COF. This configuration protects the display circuit COF and prevents burrs or sharp edges from abrading the display circuit COF when the material removal portion is formed.

[0022] Based on the first aspect, or the first embodiment of the first aspect, or the second embodiment of the first aspect, or the third embodiment of the first aspect, or the fourth embodiment of the first aspect, or the fifth embodiment of the first aspect, or the sixth embodiment of the first aspect, or the seventh embodiment of the first aspect, or the eighth embodiment of the first aspect, the embodiment of the present application further provides a ninth embodiment of the first aspect: the decorative layer also includes a buckle, which is located on the side edge of the decorative layer that does not abut the screen surface, and correspondingly, a bayonet adapted to the buckle is provided on the bracket. Thus, on the basis of the adhesive fixed connection relationship between the components established by the first adhesive layer and the second adhesive layer, supplemented by the snap-fit ​​fixed connection method established by the adapted buckle and bayonet, the connection reliability of the protective component can be improved, and the assembly processability is better.

[0034] The embodiments of the present application provide a solution for ultra-thin electronic devices. In specific applications of electronic devices such as smart TVs and monitors, the solution effectively reduces the thickness of display screen components while taking into account the user's visual experience.

[0035] Without loss of generality, this embodiment uses the protective component 10 as the description subject. Figure 1 In the display device 100 shown in FIG, the protective assembly 10 is located at the bottom side edge of the display assembly 20. The structure and assembly relationship of the protective assembly 10 are described in detail below. It should be understood that the display assembly 20 of the electronic device can be an LCD or LED display depending on the design requirements of different products. The specific implementation of the display assembly is not the core invention of this application and does not constitute a substantial limitation on the electronic device for which protection is sought.

[0036] Example 1

[0037] See Figure 1 In the display device provided in this embodiment, the display screen assembly 20 employs an LCD (Liquid Crystal Display) display screen 201, and the speaker 30 is located at the bottom of the display screen assembly 20. A protective assembly 10 is provided outside the speaker 30, along the bottom side of the display screen assembly 20. The directional terms "outside" and "inside" and "beside" used herein, as well as the directional terms "inside" and "beside" used below, are defined relative to the display device itself to clearly describe the relative positional relationships between the components or structures of the solution.

[0038] The protective component 10 includes a decorative layer 1, a bracket 2 and a buffer layer 3, combined with Figure 2 and Figure 3 As shown, the decorative layer 1 is located outside the display assembly 20 and the bracket 2. The bracket 2 is located beside the display assembly 20 and is fixed to the side edge of the display assembly 20 to establish a basic fixed connection between the protective assembly 10 and the display assembly 20. In actual application, different methods can be used to fix it according to the different structural designs of the display assembly 20, such as but not limited to using Figure 2 The threaded fastener 8 shown in the figure fixes the bracket 2 to the fixed structure 202 on the back of the display screen 201; that is, the bracket 2 does not occupy the assembly space on the screen surface, and the above-mentioned fixed connection is established only through the side end surface structure of the display screen assembly 20.

[0039] Combine Figure 3 and Figure 5As shown, the bracket 2 has a first surface 21 located adjacent to the screen surface 2011 of the display assembly 20. The first portion of the decorative layer 1 is bonded to the first surface 21 of the bracket 2 via a first adhesive layer 4, while the second portion of the decorative layer 1 abuts against the screen surface via a buffer layer 3. The "first portion" and "second portion" herein refer to two functional areas on the main body of the decorative layer 1. The "second portion" is used to press against the screen surface, while the "first portion" is used to bond to the first surface of the bracket 2 to achieve basic fixation of the decorative layer 1. It should be understood that the "first portion" and "second portion" may be different areas on the main body of the decorative layer 1.

[0040] Optionally, the decorative layer 1 may be a planar structure, with the first portion and the second portion located on the planar structure. The decorative layer may also be a bent structure, combined with Figure 2 and Figure 3 As shown, a portion of the first portion 1b and the second portion 1a are located on the same plane, and another portion 13 of the first portion 1b is bent to another plane. Accordingly, a slot 26 can be provided on the first surface 21 of the bracket 2, and the bent portion 13 can be fitted into the slot 26 of the bracket 2. In this way, a more reliable fit and fixation relationship can be achieved.

[0041] like Figure 2 As shown, at a position corresponding to the trumpet of the speaker 30, the bracket 2 is provided with a avoidance opening 22, and the first adhesive layer 4 is provided with a avoidance opening 41 to establish a sound channel; accordingly, a speaker mesh structure 11 is configured on the decorative layer 1 at least in the area corresponding to the avoidance openings (22, 41). With this arrangement, the decorative layer 1 used to press against the display screen 201 also has the function of the speaker mesh of the speaker 30, or in other words, it is equivalent to the function of pressing against the display screen 201 realized by the speaker mesh of the speaker 30.

[0042] After assembly, the bracket 2 is located inside the decorative layer 1, and the decorative layer 1 outside the bracket 2 is pressed against the display screen 201. Figure 4 As shown, based on the characteristic that the front outer dimensions are limited by the decorative layer 1, the thickness of the protective component 10 can be effectively reduced by reasonably controlling the thickness of the decorative layer 1 and the buffer layer 3; at the same time, the display device provided in this embodiment integrates the speaker mesh and the decorative layer pressed against the display screen into one, while effectively reducing the thickness, the user can perceive the front sound, which can further improve the user's visual experience.

[0043] In this embodiment, the decorative layer 1 can be made of a different material than the bracket 2. For example, but not limited to, the bracket 2 can be made of lightweight plastic to control the weight of the entire device. The decorative layer 1 can be made of a relatively rigid metal material, such as, but not limited to, stainless steel. This allows the thickness of the decorative layer 1 to be minimized while still providing reliable pressure against the display screen. For example, using SUS304 stainless steel, a decorative layer 1 with a thickness of 0.3 mm can be produced, and a minimum gap of 0.4 mm between the decorative layer 1 and the screen surface 2011 can be maintained.

[0044] In practical applications, the first surface 21 of the bracket 2 that is in contact with the decorative layer 1 can be substantially flush with the screen surface 2011. Figure 5 Of course, this "roughly flush" relative positional relationship is based on the fact that the thickness of the buffer layer 3 and the first adhesive layer 4 tend to be consistent after being pressed. It can be understood that the first surface 21 does not protrude from the screen surface 2011, which makes it easier to achieve overall thickness control.

[0045] It should be understood that based on the functional properties of the speakers, the sound channels configured on the protective component 10 need to be set accordingly with the number and specific positions of the speakers 30. The display device described in this embodiment has two speakers 30, such as Figure 6 As shown, the bracket 2 is provided with avoidance openings 22 at two corresponding positions, and the first adhesive layer 4 is also provided with avoidance openings 41 at two identical positions (not shown in the figure).

[0046] Figure 3 As shown, the avoidance openings (22, 41) are hollowed out as a whole, and the specific size and shape can be opened according to the overall design requirements to take into account the bearing capacity of the bracket 2 body at the opening position.

[0047] Among them, combined Figure 4 As shown, the speaker mesh structure 11 can be deployed across the entire area of ​​the decorative layer 1. From the user's perspective, this is equivalent to placing the bracket 2 within the visible, complete speaker mesh area. The design of this ultra-thin protective component also gives the user the visual experience of the entire bottom surface being a speaker mesh. For example, using SUS304 stainless steel to make the decorative layer 1, the speaker mesh structure 11 can be formed on the decorative layer 1 using an etching process.

[0048] The "full-area" configuration of the speaker mesh structure 11 here refers to the placement of the speaker mesh structure 11 within the width of the decorative layer 1, while meeting the requirements for hole-forming or mesh-forming processability, to achieve the aforementioned user visual experience. It should be noted that this "full-area" configuration of the speaker mesh structure 11 includes situations with regular or irregular mesh patterns, as well as situations where an unperforated border is retained at the outer edge of the decorative layer 1.

[0049] Combine Figure 3 As shown, to further enhance the user's visual experience, the inner surface of the speaker mesh structure of this embodiment is bonded with a shielding mesh 6 via a second adhesive layer 5. That is, the shielding mesh 6 covering the inner side of the decorative layer 1 can not only meet the functional requirements of the speaker, but also provide a uniform shielding effect for the speaker mesh structure. In this way, compared to the position of the avoidance openings (22, 41), the shielding mesh 6 covering the inner surface of the speaker mesh structure makes it impossible to see the color difference on the outer side of the speaker mesh.

[0050] In practical applications, the shielding mesh 6 can be made of a mesh fabric or non-woven fabric to facilitate thickness control and reduce manufacturing and assembly costs. The second adhesive layer 5 can be a water-based adhesive layer, specifically formed by immersing the shielding mesh 6 in water-based adhesive. Because water-based adhesives use water as a solvent, the adhesive not only soaks into the surfaces of each mesh, but also into the sides of each mesh, forming a penetrating second adhesive layer 5. This enhances the overall bond between the shielding mesh 6 and the speaker mesh structure, and after curing, ensures good speaker sound permeability, thus meeting audio performance requirements.

[0051] In addition, the first adhesive layer 4 of this embodiment adopts a hot melt adhesive layer, which has good bonding processability and low manufacturing cost; in addition, based on the good affinity between hot melt adhesive and water-based adhesive, good reliability of the bonding relationship between the decorative layer 1 and the bracket 2 can be obtained.

[0052] In order to avoid light transmission, Figure 5 As shown, regarding the method of configuring a speaker mesh structure across the entire area of ​​the decorative layer 1, the first adhesive layer 4 includes an extension 42 that extends toward the buffer layer 3 and out of the bracket. The second portion of the decorative layer 1 abuts against the screen surface via the first end side 31 of the buffer layer 3. The second end side 32 of the buffer layer 3 overlaps and bonds with the extension 42 of the first adhesive layer 4. This arrangement creates a light-shielding barrier between the buffer layer 3 and the bracket 2 through the overlapping and bonding area formed between the buffer layer 3 and the first adhesive layer 4, preventing light from passing through the gap and ensuring that the display assembly maintains good display performance. Here, the first end side 31 and the second end side 32 refer to two opposing parts of the buffer layer 3, rather than referring to two separate components.

[0053] In this embodiment, the second end side 32 of the buffer layer 3 may be located on the inner side of the protruding portion 42 of the first adhesive layer 4. Figure 5 The buffer layer 3 can be a sponge strip, which is conducive to controlling the thickness.

[0054] In other practical applications, the second end side 32 of the buffer layer 3 can also be located outside the protruding portion 42 of the first adhesive layer 4, and can also achieve the light-shielding effect through the overlapping bonding area; in addition, the buffer layer 3 can also be a silicone strip or a rubber strip.

[0055] For example but not limited to, the first end side 31 of the buffer layer 3 is as follows Figure 5 As shown, it is retracted into the decorative layer 1 and has a good appearance under a reliable pressing relationship.

[0056] In this embodiment, Figure 7 and Figure 8 As shown, the display circuit COF 203 of the LCD display 201 is located at the bottom of the display 201. A clearance space 23 is provided on the bracket 2. This clearance space is located on the side of the bracket 2 near the LCD display 201 to provide clearance for the installation of the display circuit COF 203 and avoid interfering with the pin connection between the COF and the display assembly. It will be appreciated that the actual number of display circuit COFs configured depends on the specific model and size of the display 201. In this embodiment, the number and specific locations of the clearance spaces 23 on the bracket 2 need to be set accordingly.

[0057] A shielding sheet 7 is bonded and fixed to the first adhesive layer 4 at a position opposite to the avoidance space 23. Figure 7 As shown, the bent circuit COF 203 can be prevented from being bonded to the first adhesive layer 4 through the avoidance space, thereby preventing the circuit COF 203 from being bonded to the first adhesive layer 4 at this position, thereby affecting the reliable connection relationship of the pins.

[0058] In some practical applications, the clearance space 23 can be integrally formed with the bracket 2 body, or it can be machined and formed secondary. To prevent burrs or sharp edges created by the clearance space 23 from contacting and causing wear on the display circuit COF 203, the shielding sheet 7 can be extended from the first adhesive layer 4 to the second surface 24 of the bracket 2 opposite the display circuit COF 203, that is, the surface directly opposite the bottom side of the display assembly 20. The second surface 24 is perpendicular to the first surface 21. This provides for better assembly processability.

[0059] In this embodiment, the shielding sheet 7 is made of Mylar, which is easy to shape according to the internal structure space and has low manufacturing cost.

[0060] In order to improve the integrated connection reliability of the protection component 10, a buckle 12 is provided on the side edge of the decorative layer 1, such as Figure 9 As shown, the bracket 2 is provided with a snap-in 25 adapted to the snap-in 12. Of course, based on the adaptive relationship between the top side edge of the decorative layer 1 and the screen surface, the snap-in 12 can be provided on the side edge of the decorative layer 1 that is not in contact with the screen surface, specifically, on the left, right, and bottom side edges of the decorative layer 1.

[0061] The matching buckle 12 and the bayonet 25 can be realized in different structural forms, as long as they can establish a fixed connection between the decorative layer 1 and the bracket 2. Figure 9 and Figure 10 The two figures illustrate the snap-fit ​​structure at one end of the protective assembly 10. In this embodiment, one snap 12 is provided on each of the short sides (left and right sides) of the decorative layer 1, and multiple snaps 12 are provided at intervals along the long sides (bottom) of the decorative layer 1. As shown in the figures, each snap 12 is formed by bending inward from the corresponding side of the decorative layer 1. The bracket 2 is attached to the decorative layer 1, and each snap 12 is locked into place with a corresponding bayonet 25.

[0062] The following briefly describes the main process steps for manufacturing and assembling the protective assembly 10 of this embodiment:

[0063] 1. Produce a decorative layer 1 having a speaker mesh structure 11 and a bracket 2 having an avoidance opening;

[0064] 2. Dip the shielding mesh 6 in water-based glue to form a second glue layer 5 running through it, and then adhere the shielding mesh 6 to the speaker mesh structure 11 through the second glue layer 5;

[0065] 3. Adhere the first component to the first surface of the bracket 2 using the first adhesive layer 4 (hot melt adhesive);

[0066] 4. The bracket 2 is attached to the decorative layer 1, and each buckle 12 is engaged with the corresponding bayonet 25 to be positioned;

[0067] 5. Adhere the second end side 32 of the buffer layer 3 to the protruding portion 42 of the first adhesive layer 4 extending from the bracket 2;

[0068] 6. Cover the shielding sheet 7 made of Mylar on the first adhesive layer 4 at a position opposite to the avoidance space of the bracket 2 to form a protective component 10.

[0069] Finally, the protective component 10 is assembled to the bottom side edge of the display screen assembly 20, the bracket 2 is fixed to the fixed structure 202 of the display screen assembly through threaded fasteners, and the decorative layer 1 is pressed against the screen surface 2011 through the first end side 31 of the buffer layer 3; at this point, after the assembly of the protective component 10 and the display screen assembly is completed, the installed speaker 30 is fixed to the fixed structure 202.

[0070] The display device 100 provided in this embodiment realizes an ultra-thin protective component 10 with integrated sound-speaking function based on the ultra-thin decorative layer 1 and the small gap design after the decorative layer 1 is pressed against the screen surface 2011 .

[0071] Example 2

[0072] See Figure 11In this embodiment, the protective assembly 10' is also disposed along the bottom side edge of the display screen assembly 20. The difference from the first embodiment is that the display device provided in this embodiment does not have a speaker disposed at the bottom. To clearly illustrate the differences and connections between this embodiment and the first embodiment, identical functional components and structures are indicated with the same reference numerals in the figures.

[0073] In this embodiment, the protective assembly 10' includes a decorative layer 1', a bracket 2', and a buffer layer 3'. The decorative layer 1' is located outside the display assembly 20 and the bracket 2'. The specific configuration of the protective assembly 10' does not need to take into account the function of the speaker, and the combination is simpler.

[0074] As shown in the figure, the decorative layer 1′ located on the outside of the display screen assembly 20 and the bracket 2′ is bonded to the first surface 21′ of the bracket 2′ through the first adhesive layer 4′, and is abutted against the screen surface 2011 through the buffer layer 3′. Similarly, by reasonably controlling the thickness of the decorative layer 1′ and the buffer layer 3′, the thickness of the protective assembly 10′ can be effectively reduced.

[0075] The materials of the decoration layer 1 ′, the bracket 2 ′ and the buffer layer 3 ′ are the same as those in the first embodiment and will not be described in detail here.

[0076] It should be noted that the structure associated with the mounting position of the display screen circuit COF (not shown in the figure), the removed material portion and the shielding sheet (not shown in the figure) formed at the corresponding position of the bracket 2' in this embodiment can also be processed in the same manner as in the first embodiment. Detailed description will not be given here.

[0077] In addition, the design solutions of the ultra-thin protective components provided in the above-mentioned first and second embodiments can be applied to other products equipped with liquid crystal screens.
