Detailed Implementation

[0036] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0037] In view of this, in order to solve the above problems, please refer to the following: Figures 1-5 This embodiment provides a bracket assembly 1 for use in a mobile terminal. The bracket assembly 1 includes a bracket body 11 and a decorative piece 12. The bracket body 11 is mounted on the mid-frame of the mobile terminal. The bracket body 11 has a first surface 111 and a second surface 112 disposed opposite to each other. The first surface 111 of the bracket body 11 faces the mid-frame and includes a limiting portion 1111 for fixing electronic components. The second surface 112 is provided with a plurality of appearance partitions 113 and a spacing groove 114. The spacing groove 114 is disposed between two adjacent appearance partitions 113. The decorative piece 12 is disposed on the second surface 112 and is disposed on one or more of the plurality of appearance partitions 113.

[0038] The bracket assembly 1 provided in this embodiment combines the bracket body 11 with the decorative piece 12, thereby improving the appearance of the bracket body 11 and achieving a structure that allows for flexible splicing and replacement of different appearance textures. The bracket assembly 1 is applied to a mobile terminal, which includes, but is not limited to, mobile phones, tablets, laptops, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc. This embodiment does not limit the type of mobile terminal.

[0039] The bracket body 11 has a first surface 111 and a second surface 112. The first surface 111 and the second surface 112 are arranged opposite to each other. Alternatively, the first surface 111 can be understood as the back side and the second surface 112 as the front side.

[0040] The mid-frame serves as the skeleton of the mobile terminal, providing stable support for internal electronic components such as the screen, battery, motherboard, and camera. This ensures that all components are tightly connected and precisely positioned, allowing the device to maintain its integrity and stability during daily use. Optionally, the mid-frame has an annular groove, within which the bracket body is housed.

[0041] Optionally, the first surface 111 is used to fix, install, or mount electronic components, that is, the electronic components abut against the first surface 111 to fix the electronic components on the bracket body 11. For example, the first surface 111 is used to fix a battery.

[0042] The first surface 111 is provided with a limiting part 1111. Optionally, the limiting part 1111 can be a limiting protrusion, a limiting groove, a limiting buckle, etc. This embodiment does not limit it.

[0043] Optionally, the mobile terminal also includes a cover plate disposed on the side of the bracket body 11 opposite to the battery, and a decorative piece 12 disposed between the bracket body 11 and the cover plate. The cover plate abuts against the second surface 112 to fix the cover plate to the bracket body 11. For example, the mobile terminal is a mobile phone, and the cover plate is the glass cover of the mobile phone.

[0044] The second surface 112 is provided with multiple appearance partitions 113 and spacer grooves 114. The spacer grooves 114 can also be understood as grooves. They do not divide the bracket body 11, but only divide the multiple appearance partitions 113. The bracket body 11 is still a connected sheet structure. In this embodiment, the spacer grooves 114 are used to space adjacent appearance partitions 113, which not only facilitates the positioning of different appearance partitions 113 and reduces the difficulty of subsequent installation of decorative pieces 12, but also further improves the appearance performance of the bracket body 11.

[0045] Specifically, the appearance partition 113 can be made into textures of different shapes and depths according to the design. Furthermore, the appearance partition 113 can be used as an independent texture decoration, or decorative pieces 12 can be placed on the appearance partition 113 to obtain different appearance effects.

[0046] Decorative pieces 12 are disposed on exterior partitions 113 for decorative purposes. For example, decorative pieces 12 may be disposed on one exterior partition 113. Alternatively, decorative pieces 12 may be disposed on multiple exterior partitions 113. Optionally, the decorative pieces 12 can be connected to the bracket body 11 by adhesive bonding, snap-fit ​​bonding, splicing bonding, etc. For example, decorative pieces 12 may be attached to the bracket body 11 using adhesive. Alternatively, decorative pieces 12 may have a first snap-fit ​​portion, and the bracket body 11 may have a second snap-fit ​​portion, with the first snap-fit ​​portion and the second snap-fit ​​portion being snap-fit ​​connected.

[0047] Optionally, the decorative piece 12 can be a decorative film, decorative insert, etc. For example, the decorative piece 12 can be a PET film with an appearance, an injection-molded part with an appearance texture, etc. The number of decorative pieces 12 is at least one. Optionally, multiple decorative pieces 12 are arranged at intervals. Optionally, multiple decorative pieces 12 are arranged in an array.

[0048] Optionally, the decorative piece 12 includes a functional marker 121, which is correspondingly disposed with respect to components inside the mobile terminal for user identification. Further optionally, the functional marker 121 is correspondingly disposed with respect to an NFC, for example, the NFC may be located below the functional marker 121, or near the functional marker 121.

[0049] In summary, the bracket assembly 1 provided in this application can not only be used to fix the internal components of the mobile terminal, but also serve as an external display by designing multiple appearance partitions 113 and spacing slots 114 on the second surface 112 of the bracket body 11, thereby enhancing the overall aesthetics of the mobile terminal. The decorative piece 12 can cover part of the bracket assembly 1, and by limiting the attachment position, the appearance partitions 113 combined with the spacing slots 114 can highlight the corresponding functional areas of the mobile terminal, making it easy for users to quickly identify the location of the internal functional components of the mobile terminal, enhancing the information transmission of the mobile terminal and improving the user experience.

[0050] Please refer to this as well. Figures 1-5 In one embodiment, the mobile terminal includes functional components, at least a portion of which are used to receive external signals and are installed in conjunction with the bracket assembly 1.

[0051] The bracket body 11 is provided with a clearance hole 1151 that passes through the first surface 111 and the second surface 112. The clearance hole 1151 is used to allow some of the functional components to pass through the clearance hole 1151.

[0052] And / or, the second surface 112 is provided with a receiving groove 1152 for receiving part of the functional component.

[0053] Functional components include, but are not limited to, cameras, NFC, sensors, pressure-sensitive buttons, and ribbon cables; this embodiment does not limit these. At least some of the functional components are used to receive external signals. For example, a camera can receive external light signals; an NFC can receive external wireless signals; and a pressure-sensitive button can receive external pressure signals.

[0054] Furthermore, in one embodiment, the bracket body 11 is provided with the clearance hole 1151 and the receiving groove 1152. The functional component includes a ribbon cable and a sensor. The ribbon cable connects the sensor and the circuit board. The sensor is disposed on the second surface 112. The circuit board is disposed on the middle frame and faces the first surface 111. The clearance hole 1151 is used to allow the ribbon cable to pass through the bracket assembly 1. The receiving groove 1152 is used to embed the ribbon cable.

[0055] For example, the sensor is a pressure sensor, which is located on the second surface 112. The circuit board is located on the middle frame, and the ribbon cable is connected to the circuit board. The ribbon cable passes through the clearance hole 1151 and is embedded in the receiving groove 1152. The ribbon cable is a pressure sensor FPC.

[0056] The pressure sensor receives the pressure transmitted from the deformation of the cover plate and generates a detection signal to control the functional components of the mobile terminal.

[0057] Functional components can be placed on the back or side of the mobile terminal. These components can be light strips, light arrays, flashlights, speakers, microphones, etc., enabling certain functions to be realized on the back of the mobile terminal (such as turning the light strip on and off, switching display content, and starting recording), thus reducing the use of the front screen of the mobile terminal.

[0058] In addition to the sensor, the functional components in the above embodiments also include many electronic devices. Since these electronic devices all need to be connected to the circuit board, which is not visible from the exterior, they all need to pass through the bracket body 11 to connect to the circuit board. Besides the sensor, these electronic devices can also be LED strips, LED beads, LED arrays, wireless charging coils, charging coils, etc. This design allows for a greater degree of integration of electronic devices onto the exterior surface while maintaining aesthetic appeal, especially for designs with visual effects (such as LED strips, LED arrays, and coil textures), thus increasing design flexibility and providing users with a new aesthetic experience.

[0059] This embodiment provides more design space and gives users more new appearance experiences by providing a clearance hole 1151 on the bracket body 11 so that functional components can pass through the clearance hole 1151.

[0060] The functional component is installed in conjunction with the bracket assembly 1. For example, the functional component is fixed to the bracket body 11; or the functional component is inserted through the bracket body 11.

[0061] The bracket body 11 is provided with at least one clearance hole 1151. Optionally, the clearance hole 1151 is provided within at least one appearance partition 113. Optionally, at least some of the clearance holes 1151 have different diameters. Optionally, at least some of the clearance holes 1151 have different depths. Optionally, multiple clearance holes 1151 are spaced apart. Optionally, the shape of the clearance hole 1151 can be circular, rectangular, polygonal, rhomboid, etc., and this embodiment is not limited in this respect.

[0062] For example, the clearance hole 1151 is used to fix inner components, and / or, to fix outer components, and / or, as a ribbon cable support area. Specifically, the camera lens can pass through the clearance hole 1151. Optionally, when a functional component is disposed within the clearance hole 1151, the functional component abuts against the wall of the clearance hole 1151. The clearance hole 1151 is used to fix the functional component.

[0063] The support body 11 is provided with at least one receiving groove 1152. Optionally, the receiving groove 1152 is located within at least one exterior partition 113. Optionally, at least some of the receiving grooves 1152 have different opening widths. Optionally, at least some of the receiving grooves 1152 have different groove depths. Optionally, multiple receiving grooves 1152 are spaced apart. Optionally, the shape of the receiving groove 1152 can be circular, rectangular, polygonal, rhomboid, etc., and this embodiment is not limited in this respect.

[0064] For example, the receiving groove 1152 is used to fix external devices and / or serve as a ribbon cable support area. Specifically, the ribbon cable may be disposed within the receiving groove 1152. Optionally, when a functional component is disposed within the receiving groove 1152, the functional component abuts against the groove wall of the receiving groove 1152. The receiving groove 1152 is used to fix and support the functional component.

[0065] Therefore, by providing clearance holes 1151 and receiving grooves 1152 in the bracket body 11, this embodiment can accommodate functional components of different sizes and types, and can fix and support functional components; in addition, clearance holes 1151 can also allow functional components to pass through the bracket body 11 and be electrically connected to other components located inside, thereby improving the reliability of the mobile terminal.

[0066] Please refer to this as well. Figures 1-5 In one embodiment, the first surface 111 and / or the second surface 112 are provided with a fixing part 116, which is used to fix the functional component of the fixing part 116.

[0067] Optionally, the fixing part 116 can be a fixing protrusion, a fixing groove, a fixing hole, a fixing buckle, etc., and this embodiment is not limited to this. The fixing part 116 can be used to fix cameras, NFC, sensors, pressure-sensitive buttons, ribbon cables, etc. For example, the fixing part 116 is used to fix inner devices, and / or, fix outer devices, and / or, serve as a ribbon cable support area.

[0068] Therefore, this embodiment improves the reliability of the mobile terminal by providing a fixing part 116 on the first surface 111 and / or the second surface 112 to fix inner devices, outer devices, ribbon cables, etc.

[0069] Please refer to this as well. Figures 1-5 In one embodiment, the support assembly 1 further includes a first component 13, which is movably connected to the support body 11.

[0070] The first component 13 is movably disposed on the bracket body 11, and the first component 13 is movable relative to the bracket body 11. Optionally, the connection between the first component 13 and the bracket body 11 can be a rotatable connection, a hinged connection, a sliding connection, a rolling connection, a universal connection, etc.

[0071] The first component 13 can serve both a functional and decorative purpose. Optionally, the first component 13 can be a handle, a button, a pull-out part, etc., and this embodiment is not limited to this. For example, the first component 13 can serve as a handle for the user to lift; as a button for the user to use in conjunction with other components; as a pull-out part for the user to pull out; or as a decorative element to improve the appearance of the mobile terminal. Specifically, the first component 13 can be configured according to the user's requirements and used in conjunction with the bracket body 11 to achieve different effects.

[0072] Therefore, by setting the first component 13, this embodiment greatly improves the design space for the free transformation of the support assembly 1, provides convenience for realizing diversified structural design, and greatly improves the user experience.

[0073] Please refer to this as well. Figures 1-5 In one embodiment, the first component 13 includes a handle 131, which is rotatably connected to the second surface 112; when the handle 131 is pulled away from the mobile terminal, the handle 131 can cause the bracket body 11 to separate from the mobile terminal.

[0074] Specifically, when it is not necessary to disassemble the bracket body 11, the handle 131 can be placed close to the second surface 112 to avoid interfering with other components. When it is necessary to disassemble the bracket body 11, the handle 131 can be pulled and rotated to apply an external force to the handle 131 in a direction away from the mobile terminal, thereby separating the bracket body 11 from the mobile terminal through the handle 131, thus realizing the disassembly of the bracket body 11.

[0075] Therefore, by providing a handle 131, this embodiment facilitates the user's disassembly of the bracket body 11, reducing the difficulty of disassembly and improving the user's experience.

[0076] Please refer to this as well. Figures 1-6 In one embodiment, the bracket assembly 1 further includes a second bracket 14, which partially overlaps with the bracket body 11 at one end away from the handle portion 131 in the projection direction toward the middle frame, and is fitted and connected in the overlapping area by a clip 141.

[0077] Part of the second bracket 14 overlaps with part of the bracket body 11. The end of the second bracket 14 near the bracket body 11 overlaps with the end of the bracket body 11 near the second bracket 14, which facilitates installation and improves the connection performance between the second bracket 14 and the bracket body 11.

[0078] Furthermore, the second bracket 14 is engaged with the bracket body 11 at the end away from the handle portion 131 via a locking member 141; the engagement of the second bracket 14 with the bracket body 11 via the locking member 141 can also be understood as the second bracket 14 being snap-fitted to the bracket body 11. Optionally, the locking member 141 is located on the bracket body 11; or, the locking member 141 is located on the second bracket 14. For example, the second bracket 14 is used to fix inner components and / or, to fix outer components.

[0079] The mobile terminal includes functional components, and the second bracket 14 is used to fix some of the functional components. These functional components include, but are not limited to, an LED array, a flash, a camera, and a motherboard, etc., and this embodiment does not limit the specific components. For example, the LED array is fixed to the second bracket 14; another example is that the flash is fixed to the second bracket 14; yet another example is that the camera is fixed to the second bracket 14; and yet another example is that the motherboard is fixed to the second bracket 14.

[0080] Therefore, this embodiment improves the reliability of the mobile terminal by providing a second bracket 14 that cooperates with the bracket body 11 to fix functional components, etc.

[0081] Please refer to this as well. Figures 1-5 In one embodiment, the bracket body 11 is an injection molded part obtained by multi-hole injection molding from the second surface 112, the second surface 112 being provided with a plurality of injection holes 117; the decorative piece 12 covers at least part of the avoidance hole 1151, or the receiving groove 1152, or the injection hole 117.

[0082] The inventors discovered that for visible battery holders, related technologies typically employ non-visual component designs or pure PET film solutions, resulting in a monotonous appearance and a lack of textured, three-dimensional design effects. Alternatively, they use compression molding, which imposes high limitations on texture, prevents perforation, and severely restricts the draft angle of the battery holder. Compression-molded integrated battery holders can only process products with simple structures and no complex structures such as snap-fit ​​parts, and require pre-reserved injection skirts. After compression molding, computer numerical control (CNC) is needed to remove the side gates, severely affecting the visual effect of the battery holder's sidewalls and lacking a three-dimensional depth effect. This severely limits the design of the structure and makes it impossible to achieve flexible combinations of complex structures or diverse appearances.

[0083] Optionally, an appearance partition 113 is provided with at least one injection hole 117. Optionally, a plurality of injection holes 117 are arranged around the clearance hole 1151.

[0084] Therefore, this embodiment uses injection molding combined with multi-point glue injection on the second surface 112 to hide the glue injection hole 117 in the bonding surface of the decorative piece 12. This avoids the burrs formed by injection molding from affecting the battery, as burrs may puncture the battery film and cause short circuits, leakage, and other consequences. It also improves the appearance performance of the bracket assembly 1.

[0085] The following is a detailed description of the fabrication process of scaffold assembly 1:

[0086] The first step is to injection mold an integral bracket body 11 using a front-side injection molding method. The second surface 112 of the bracket body 11 has multiple appearance partitions 113.

[0087] The second step is to use computer numerical control (CNC) technology to remove the glue inlet on the second surface 112.

[0088] The third step is to assemble the decorative piece 12 onto the second surface 112.

[0089] Optionally, in the first step, the gate position can be adjusted through mold flow analysis to optimize the product deformation trend. Simultaneously, the flatness of the integrated bracket body 11 can be corrected by the temperature difference between the front and rear molds, thereby further improving the appearance performance of the bracket assembly 1.

[0090] Alternatively, the temperature difference between the front and rear molds can be 10℃ to 15℃.

[0091] The decorative piece 12 covers a portion of the clearance hole 1151, or the decorative piece 12 covers all of the clearance hole 1151. The decorative piece 12 covers a portion of the receiving groove 1152, or the decorative piece 12 covers all of the receiving groove 1152. The decorative piece 12 covers a portion of the glue injection hole 117, or the decorative piece 12 covers all of the glue injection hole 117.

[0092] Therefore, this embodiment further improves the appearance performance of the bracket assembly 1 by providing a decorative piece 12 to cover and hide at least part of the clearance hole 1151, or the receiving groove 1152, or the glue injection hole 117.

[0093] Please refer to this as well. Figures 1-5 In one embodiment, the second surface 112 is provided with a mounting groove 118, and the decorative piece 12 is disposed in the mounting groove 118.

[0094] The number of mounting slots 118 is at least one, and optionally, the mounting slots 118 are provided within one or more appearance partitions 113. Optionally, at least some of the mounting slots 118 have different opening widths. Optionally, at least some of the mounting slots 118 have different groove depths. Optionally, multiple mounting slots 118 are spaced apart. Optionally, the shape of the mounting slot 118 can be circular, rectangular, polygonal, rhomboid, etc., and this embodiment is not limited in this respect. The decorative piece 12 is fixed within the mounting slot 118 and covers the bottom wall of the mounting slot 118.

[0095] In summary, this embodiment, by providing a mounting groove 118 on the second surface 112, can accommodate decorative pieces 12 of various sizes and types, so as to fix the decorative pieces 12 and facilitate users to flexibly combine and replace different appearance textures. Furthermore, by providing the mounting groove 118, the bracket body 11 and the decorative pieces 12 are made more flat in appearance, thereby further improving the appearance performance of the bracket assembly 1 and enhancing the user experience.

[0096] Please refer to this as well. Figures 1-5 In one embodiment, the plurality of appearance partitions 113 are arranged in an array, and at least some of the appearance partitions 113 have different heights or textures.

[0097] For example, some of the appearance partitions 113 may have different heights. Or, all of the appearance partitions 113 may have different heights. Still, within one appearance partition 113, some parts may have different heights, or all of them may have different heights, or all of them may have the same height.

[0098] For example, some appearance partitions 113 may have different textures. Alternatively, all appearance partitions 113 may have different textures. Yet another example is that within an appearance partition 113, some textures may be different, or all textures may be different, or all textures may be the same.

[0099] Therefore, by designing appearance partitions 113 with different heights, this embodiment can not only use itself as an appearance display to improve the three-dimensional depth effect, but also set decorative pieces 12 of various sizes to realize flexible splicing and replacement of different appearance textures, thereby greatly improving the design space for the free transformation of the texture effect of the support component 1, providing convenience for realizing diversified structural design, and improving the user experience.

[0100] Furthermore, the multiple appearance partitions 113 are arranged in an array to facilitate user location and identification of each appearance partition 113, further improving the user experience.

[0101] In one embodiment, the minimum thickness of the support body 11 is greater than or equal to 0.45 mm.

[0102] The minimum thickness of the support body 11 can be exemplified by 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm, etc. The minimum thickness of the support body 11 can also be understood as the thickness of the thinnest part of the support body 11. For example, the thickness at the gap groove is the minimum thickness of the support body 11.

[0103] If the minimum thickness of the bracket body 11 is less than 0.45mm, it is prone to warping and deformation after injection molding and cooling due to its thinness. This is especially true for the grooves on the bracket body 11, which are more susceptible to warping and deformation. Particularly when the cover is a transparent back cover, almost all parts of the bracket assembly 1 facing the cover constitute the appearance of the mobile terminal. If warping and deformation occur, it will have a significant impact on the visual appeal and affect the product's aesthetic appeal.

[0104] Therefore, this embodiment limits the thickness of the thinnest part of the support body 11 to be greater than or equal to 0.45 mm to ensure the overall structural rigidity of the support body 11 and improve the stability and reliability of the support body 11.

[0105] In the bracket body 11, the absolute value of the height difference between two adjacent appearance partitions 113 is less than or equal to 0.2 mm.

[0106] The absolute value of the height difference between two adjacent appearance sections 113 can be 0, 0.05mm, 0.1mm, 0.15mm, or 0.2mm, etc.

[0107] Optionally, the thickness of the plurality of appearance partitions 113 gradually increases along the width or length direction of the support body 11. For example, the thickness of the plurality of appearance partitions 113 increases linearly along the width or length direction of the support body 11, or the thickness of the plurality of appearance partitions 113 increases non-linearly.

[0108] Therefore, this embodiment limits the absolute value of the height difference between two adjacent appearance partitions 113 to less than or equal to 0.2mm, thereby avoiding excessive thickness difference between two adjacent appearance partitions 113, which makes it less likely to cause warping and shadows, thereby further improving the appearance performance of the bracket assembly 1 and enhancing the user experience.

[0109] Please refer to this as well. Figures 1-5 In one embodiment, the mobile terminal includes a cover plate, the bracket assembly 1 is disposed between the cover plate and the middle frame of the mobile terminal, and the second surface 112 is provided with a mounting protrusion 119 for abutting against the cover plate.

[0110] Alternatively, the cover plate may be provided with a groove, and the mounting protrusion 119 may be embedded in the groove.

[0111] The cover plate is fixed to the second surface 112 and is used to fix and protect the components of the mobile terminal. For example, the mobile terminal is a mobile phone, and the cover plate is the glass cover of the mobile phone. Optionally, the cover plate is a transparent cover plate, so that the user can observe the bracket assembly, which can not only improve the overall aesthetics of the mobile terminal, but also quickly identify the location of the internal functional components of the mobile terminal, thereby enhancing the information transmission of the mobile terminal.

[0112] The second surface 112 is provided with at least one mounting protrusion 119. Optionally, the mounting protrusion 119 is located within at least one appearance partition 113. Optionally, multiple mounting protrusions 119 are spaced apart. Optionally, the shape of the mounting protrusion 119 can be circular, rectangular, polygonal, rhomboid, etc., and this embodiment is not limited in this respect. For example, the end of the mounting protrusion 119 near the cover plate directly abuts against the cover plate. As another example, the side of the cover plate facing the bracket body 11 is provided with a groove, and the mounting protrusion 119 is embedded in the groove.

[0113] In summary, this embodiment improves the connection performance between the bracket body 11 and the cover plate by setting the mounting protrusion 119, thereby improving the stability and reliability of the bracket assembly 1 and enhancing the user experience.

[0114] Please refer to this as well. Figures 1-5 In one embodiment, the bracket body 11 is an injection molded part obtained by multi-hole injection molding from the second surface 112. The second surface 112 is provided with a plurality of injection holes 117. The bracket body 11 includes a clearance area with clearance holes 1151 and a non-clearance area. The density of injection holes 117 in the clearance area is greater than the density in the non-clearance area.

[0115] The clearance area is provided with clearance holes 1151, while the non-clearance area is not provided with clearance holes 1151. In the clearance area, multiple injection holes 117 are arranged around the periphery of the clearance holes 1151. The number of injection holes 117 in the clearance area is greater than the number of injection holes 117 in the non-clearance area.

[0116] During the fabrication of the support body 11, multiple injection holes 117 are provided in the avoidance area to reduce stress and adapt to the flowability of the adhesive.

[0117] Therefore, this embodiment reduces stress, adapts to the flowability of the adhesive, reduces the manufacturing difficulty of the stent body 11, and improves the reliability of the stent body 11 by limiting the density of the injection holes 117 in the avoidance area to be greater than that in the non-avoidance area.

[0118] In one embodiment, the plurality of appearance partitions 113 are respectively obtained by splicing multiple molds in one injection molding, and at least two molds on the surface of the plurality of molds have different heights or textures.

[0119] Optionally, one appearance partition 113 corresponds to one mold. Different sizes and textures of molds can be set according to the user's needs, thus obtaining different appearance partitions 113. For example, some molds are the same, while other molds are different. Or, for example, all molds are different.

[0120] For example, some molds may have different heights. Or, all molds may have different heights. Or, within a single mold, some parts may have different heights, or all parts may have different heights, or all parts may have the same height.

[0121] For example, some molds may have different textures. Or, all molds may have different textures. Or, within a single mold, some textures may be different, or all textures may be different, or all textures may be the same.

[0122] Optionally, the second surface 112 is further provided with a mold assembly line, which is covered by the decorative piece 12. The mold assembly line is the line formed by the edges of multiple molds joined together. By hiding the mold assembly line beneath the decorative piece 12, the appearance of the bracket assembly 1 is further improved, enhancing the user experience.

[0123] Therefore, this embodiment uses molds to prepare the appearance partitions 113, enabling the support body 11 to have a rich variety of appearance textures and allowing for flexible splicing and replacement of different appearance textures. This greatly improves the design space for freely changing the texture effects on the support body 11. Furthermore, the splicing and connection between multiple molds facilitates flexible splicing and replacement during preparation, reducing the difficulty and cost of preparation.

[0124] This application also provides a mobile terminal, which includes a battery and a bracket assembly 1 as described above.

[0125] In one embodiment, the bracket body 11 is provided with a clearance hole 1151 penetrating the first surface 111 and the second surface 112, and a receiving groove 1152 provided on the second surface 112.

[0126] The mobile terminal includes a transparent back cover and functional components. The functional components include a sensor and a ribbon cable. The ribbon cable connects the sensor and a circuit board. The sensor is disposed on the second surface 112 or on the transparent back cover corresponding to the second surface 112. The circuit board is disposed on the middle frame and faces the first surface 111. The clearance hole 1151 is used to allow the ribbon cable to pass through the bracket assembly. The receiving groove 1152 is used to embed the ribbon cable.

[0127] In summary, the mobile terminal provided in this embodiment, by adopting the bracket assembly 1 provided above, can not only be used to fix the internal components of the mobile terminal, but also, by designing multiple appearance partitions 113 and spacing slots 114 on the second surface 112 of the bracket body 11, can also serve as an appearance display, enhancing the overall aesthetics of the mobile terminal; the decorative piece 12 can cover part of the bracket assembly 1, and by limiting the attachment position, the appearance partitions 113 combined with the spacing slots 114 can highlight the corresponding functional areas of the mobile terminal, making it easy for users to quickly identify the location of the internal functional components of the mobile terminal, enhancing the information transmission of the mobile terminal, and improving the user experience.
