Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a screen assembly and an electronic device. Background Technology

[0002] With the continuous development and updating of electronic technology, convenient mobile terminal devices, such as mobile phones, tablets, and laptops, have become increasingly common in people's daily lives. To meet users' high usage demands, these electronic devices are gradually developing towards thinner and lighter designs.

[0003] An electronic device may include a display module, a mid-frame, and a back cover, with the display module and back cover located on opposite sides of the mid-frame along its thickness direction. The mid-frame may include a middle plate and a bezel, with the bezel surrounding the middle plate. The back cover is mounted on one side of the bezel, and the inner wall of the other side of the bezel has a raised support platform. Taking a liquid crystal display (LCD) module as an example, the LCD display module may include a supporting back plate and a display screen mounted on the supporting back plate. The supporting back plate can be fitted onto the supporting platform to assemble the display module with the mid-frame. A gap exists between the supporting back plate and the middle plate, allowing the display module, middle plate, and bezel to form an accommodating space within which the various structural components of the electronic device can be assembled.

[0004] However, the aforementioned electronic devices are large in thickness and heavy, which cannot meet the design requirements for thinner and lighter electronic devices. Utility Model Content

[0005] This application provides a screen assembly and an electronic device that can further reduce the weight and thickness of the electronic device, thus meeting the requirements for a thinner and lighter design of the electronic device.

[0006] The first aspect of this application provides a screen assembly for use in an electronic device, including a display screen and a mid-frame support member. One side of the mid-frame support member has a receiving groove, and the display screen is disposed in the receiving groove. The side of the display screen facing the mid-frame support member is in contact with the bottom surface of the receiving groove, thereby realizing the assembly and fixation of the display screen and the mid-frame support member, and realizing the open-cell assembly of the display screen and the mid-frame support member.

[0007] When assembling electronic devices, the mid-frame support is fitted inside the bezel, with the side of the mid-frame support facing away from the display screen being assembled with the back cover. The mid-frame support and the back cover form a receiving space, enabling the assembly of the display screen, bezel, and back cover. In other words, the mid-frame support serves to support the display screen and facilitate its assembly. The display screen is directly attached to one side of the mid-frame support, allowing for assembly with the bezel, back cover, and other components. This eliminates the need for a separate backplate to support the display screen, enabling a bezel-less design. This allows for a thinner and lighter screen assembly, reducing the overall thickness and weight of the electronic device and facilitating the design requirements for slim and lightweight electronic devices.

[0008] The mid-frame support also provides an assembly space for the various structural components of the electronic device. These components can be assembled on the side of the mid-frame support facing away from the display screen. Compared with electronic devices in related technologies, the display screen is directly attached to one side of the mid-frame support, which eliminates the need for the adhesive layer between the support back plate and the middle plate (mid-frame support) and the gap between them. This further reduces the thickness and weight of the screen assembly, making the electronic device thinner and lighter, and achieving a lightweight design for the electronic device.

[0009] In one possible implementation, one edge of the mid-frame support has a notch structure. The display screen includes a display panel and a circuit board. The display panel is located within a receiving slot. One end of the circuit board is electrically connected to the display panel, and a portion of the circuit board passes through the notch structure. The other end of the circuit board is located on the side of the mid-frame support facing away from the display panel. The notch structure allows the other end of the circuit board to wrap around to the side of the mid-frame support facing away from the display panel, facilitating connection between the circuit board and the main control board of the electronic device, achieving electrical connection between the display panel and the main control board, and ensuring electrical conductivity of the display panel.

[0010] Furthermore, by using a notch structure, the other end of the circuit board is routed around to the side of the mid-frame support that faces away from the display panel. Compared to connecting the circuit board to the main control board by going around the side of the mid-frame support or the side of the frame, this avoids the circuit board affecting the assembly of the mid-frame support and the frame, and ensures that the circuit board is not exposed. The layout is compact and has a better aesthetic appeal.

[0011] In one possible implementation, the notch structure extends to one outer surface of the mid-frame support, and the notch structure is used to allow a portion of the circuit board to pass through. The mid-frame support and the frame can be two separate structural components, with the mid-frame support fitted inside the frame, and the outer surface of the mid-frame support facing the inner surface of the frame.

[0012] By extending the notch structure to the outer surface of one side of the mid-frame support, the circuit board can pass through the notch structure from the side of the mid-frame support. Part of the circuit board is accommodated within the notch structure, allowing the other end of the circuit board to wrap around to the side of the mid-frame support away from the display panel. The size of the notch structure only needs to accommodate the size of the corresponding portion of the circuit board, which helps to reduce the size of the notch structure, ensure the strength of the mid-frame support, and improve the reliability of the screen assembly and electronic devices.

[0013] Furthermore, separating the bezel and mid-frame support into two structural components, and extending the notch structure to the outer surface of the mid-frame support, facilitates the assembly of the display screen, mid-frame support, and bezel. In actual assembly, the display screen is first placed within the receiving groove of the mid-frame support, with part of the display's circuit board passing through the notch structure from the side. The other end of the circuit board wraps around to the side of the mid-frame support facing away from the display panel. Finally, the bezel is fitted over the mid-frame support. This simple and convenient assembly method improves assembly efficiency.

[0014] In one possible implementation, the screen assembly includes a bezel that surrounds a mid-frame support, with the mid-frame support and bezel forming a single integrated structure. This enriches the structural design of the screen assembly, offering wider applicability, improving the overall strength of the screen assembly and electronic device, and simplifying assembly procedures.

[0015] In one possible implementation, the circuit board includes a flexible connecting plate and a circuit board, with one end of the flexible connecting plate electrically connected to the display panel.

[0016] The circuit board is located on the side of the mid-frame support facing away from the display panel. A portion of the flexible connecting plate passes through the notch structure, and the other end of the flexible connecting plate is electrically connected to the circuit board. The display's circuit board is divided into two parts: a flexible connecting plate and a circuit board. The flexible connecting plate enables electrical connections between the display panel and the circuit board and main control board. The flexible connecting plate passes through the notch structure. As the structural component for achieving electrical connections, the flexible connecting plate can be relatively small in size, which helps reduce the size of the notch structure, ensures high strength of the mid-frame support, and improves the reliability of the screen assembly and electronic equipment.

[0017] In one possible implementation, the notch structure allows the other end of the circuit board to pass through. Specifically, the notch structure on the mid-frame support can be relatively large, allowing the other end of the circuit board to pass through the notch structure and wrap around to the side of the mid-frame support facing away from the display panel. The portion of the circuit board located between one end and the other end is accommodated within the notch structure. This reduces the complexity and requirements of the circuit board's structural design, lowers the requirements for assembly sequence and precision, and improves assembly efficiency.

[0018] The mid-frame support also includes an assembly plate, which is set inside the notch structure and covers part of the notch structure. Under the condition that part of the circuit board is accommodated in the notch structure so that the other end of the circuit board can be wrapped around to the side of the mid-frame support away from the display panel to achieve electrical connection with the main control board, the assembly plate can improve the strength of the mid-frame support and increase the assembly layout space of the mid-frame support, which facilitates the assembly of various structural components of the electronic device.

[0019] In one possible implementation, the mid-frame support includes a mid-plate and a side frame, with the side frame surrounding the mid-plate. The side frame includes a first frame portion that protrudes from a first surface of the mid-plate. The first frame portion and the mid-plate form a receiving groove, and the display screen fits against the first surface, thus assembling the display screen with the mid-frame support. This design is simple, facilitates assembly, and helps reduce costs.

[0020] In one possible implementation, the display screen further includes a cover plate located on the side of the display panel facing away from the middle plate. The cover plate is fitted onto the end face of the first frame portion facing away from the middle plate. This facilitates the assembly of the display screen and the middle frame support, reduces assembly difficulty, and improves the overall integrity and aesthetics of the assembled middle frame support, thereby ensuring the aesthetics of the electronic device.

[0021] In one possible implementation, the side frame further includes a second frame portion that protrudes from a second surface of the middle plate, with the first and second surfaces facing each other in the thickness direction. The end face of the second frame portion facing away from the middle plate is used for assembly with the rear cover, and the second frame portion, the middle plate, and the rear cover together form an accommodating space.

[0022] The second frame protrudes from the second surface of the middle plate, and the second frame and the middle plate can also form a receiving cavity. This receiving cavity can serve as part of the receiving space formed by the middle frame support and the rear cover, thus expanding the receiving space. While ensuring the thickness of the electronic device is reduced, it is beneficial to increase the volume of the receiving space, facilitating the layout of various structural components of the electronic device within the receiving space.

[0023] In one possible implementation, the screen assembly has a thickness of 5.3mm to 5.5mm. The overall thickness of the screen assembly is relatively thin, which can effectively achieve the design of reducing the thickness of electronic devices.

[0024] In one possible implementation, the mid-frame support also includes a reinforcing member. A mounting slot is formed in the mid-plate, and the reinforcing member is disposed within the mounting slot. The reinforcing member and the sidewall of the mounting slot form a receiving chamber for assembling the battery of the electronic device. The reinforcing member is made of a material with greater strength than the mid-plate, allowing the overall strength of the reinforcing member to exceed the overall strength of the mid-plate or the mid-frame support. This improves the assembly stability and reliability of the battery, thereby enhancing the overall assembly stability and reliability of the electronic device.

[0025] In one possible implementation, the thickness of the reinforcing member is less than that of the middle plate. While ensuring that the battery assembly requirements and the shell strength requirements are met, the thickness of the reinforcing member in the battery assembly area is reduced, which increases the space in the thickness direction of the accommodating space, thereby facilitating further reduction of the thickness of the electronic device.

[0026] In one possible implementation, the thickness of the reinforcing member ranges from 0.2 mm to 0.4 mm. This ensures that the reinforcing member has good strength while making it thinner, which is more conducive to the reduction of the thickness of electronic devices.

[0027] In one possible implementation, the reinforcing member is formed from at least one of aluminum, magnesium, and stainless steel. This provides high strength, which is beneficial for meeting the strength and thinning requirements of the shell.

[0028] In one possible implementation, the mid-frame support is formed from at least one material selected from aluminum alloy and magnesium alloy. Using aluminum alloy provides high strength, ensuring support for the display screen and other components. Furthermore, the mid-frame support is thinner and lighter, facilitating further reductions in the thickness of electronic devices and the weight of the mid-frame support.

[0029] The mid-frame support component is made of magnesium alloy, which can further reduce its weight while ensuring that the high strength requirements are met.

[0030] A second aspect of this application provides an electronic device including a back cover and any of the aforementioned screen assemblies. The back cover is disposed on the side of a mid-frame support member facing away from the display screen, and the mid-frame support member and the back cover form an accommodating space. By including the screen assembly, the display screen of the screen assembly is directly fitted and assembled with the mid-frame support member, realizing an open-cell assembly of the display screen and the mid-frame support member. This eliminates the need for a support backplate, achieving a bezel-less design, making the entire screen assembly thinner and lighter, thereby reducing the overall thickness and weight of the electronic device and meeting the requirements for a thinner and lighter design of the electronic device.

[0031] In one possible implementation, the thickness of the electronic device is 5.8mm to 6.0mm. Compared to electronic devices with integrated housing architecture and sandwich architecture in related technologies, the thickness is reduced by approximately 0.3mm to 0.8mm, and the weight is reduced by approximately 3% to 12%. This enables an ultra-thin design for the electronic device, significantly reducing its weight and effectively achieving a lightweight and thin design. Attached Figure Description

[0068] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0069] This application provides an electronic device, which may include, but is not limited to, mobile phones, tablet personal computers, laptops, cameras, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, virtual reality (VR) devices (such as VR glasses, VR headsets, etc.), augmented reality (AR) devices (such as AR glasses, AR headsets, etc.), in-vehicle devices, and other electronic devices with displays.

[0070] In this embodiment, a tablet computer is used as an example for illustration.

[0071] Figure 1 This is a schematic diagram of the structure of an electronic device from a frontal view, provided as an embodiment of this application.

[0072] See Figure 1As shown, the electronic device 100 includes a housing 101 and a display screen 30. The housing 101 can serve as the main load-bearing structural component of the electronic device 100. The display screen 30 can be disposed on one side of the housing 101. The display screen 30 and the housing 101 form an accommodating space (not shown in the figure), which can be used to assemble and accommodate various structural components of the electronic device 100.

[0073] In the embodiments of this application, for ease of description, as follows: Figure 1 As shown, the width direction of the housing 101 is taken as the x-direction, the length direction of the housing 101 as the y-direction, and the height direction of the housing 101 as the z-direction. The width, length, and thickness directions of the electronic device 100 can be consistent with the x, y, and z directions mentioned above, respectively. It is understood that the length, width, and thickness in the embodiments of this application are for descriptive convenience only and do not imply any limitation on the dimensions. For example, the length can be greater than, equal to, or less than the width.

[0074] The display screen 30 can be located on one side of the housing 101 along the thickness direction (z direction) of the electronic device 100. The display screen 30 is used to display information and provide an interactive interface for the user. The side of the display screen 30 facing away from the housing 101 can serve as the display surface of the electronic device 100. For example, the display surface can serve as the front of the electronic device.

[0075] For example, display screen 30 can be a liquid crystal display (LCD) display. Of course, in some other examples, display screen 30 can also be an organic light-emitting diode (OLED) display, a micro organic light-emitting diode (MLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a light-emitting diode (LED) display, a mini organic light-emitting diode (Mini LED) display, a micro organic light-emitting diode (Micro LED) display, a quantum dot light-emitting diode (QLED) display, etc.

[0076] Figure 2 for Figure 1A schematic diagram of the structure of an electronic device from the rear view.

[0077] For example, the housing 101 may include a frame 10 and a back cover 20. The frame 10 may be an annular frame structure and may surround one side of the back cover 20. The display screen 30 may be located on the side of the frame 10 facing away from the back cover 20 (see reference). Figure 4 As shown in the diagram, the display screen 30 and the back cover 20 can be respectively mounted on opposite sides of the frame 10. For example, the display screen 30 and the back cover 20 can be respectively located on opposite sides of the frame 10 along the thickness direction (z direction).

[0078] See also Figure 2 As shown, the back cover 20 can serve as the exterior cover of the back of the electronic device 100, and the side of the back cover 20 facing away from the display screen 30 can be part of the exterior of the electronic device 100. The side of the frame 10 facing away from the receiving space can also serve as part of the exterior of the electronic device 100.

[0079] It is understandable that the thickness of the electronic device 100 can be the distance between the display surface of the display screen 30 (i.e., the side facing away from the back cover 20) and the outer surface of the back cover 20 (i.e., the side facing away from the display screen 30) along the thickness direction (z direction).

[0080] In some examples, see further. Figure 2 As shown, the back cover 20 can be a rectangular plate-like structure. Of course, in some other examples, the back cover 20 can also be a plate-like structure in the shape of a square, circle, ellipse, rounded rectangle, etc.

[0081] The outer contours of the frame 10 and the display screen 30 can match the back cover 20. For example, in this embodiment, if the back cover 20 is a rectangular plate structure, the frame 10 can be a frame structure with a rectangular outer contour, and the display screen 30 can be a thin plate structure with a rectangular outer contour.

[0082] With the continuous development of electronic device technology, in pursuit of the ultimate thin and light design, the architecture of electronic devices has gradually evolved from a sandwich architecture to a unibody architecture.

[0083] Figure 3 This is a schematic diagram of the disassembled structure of an electronic device in the related technology.

[0084] For example, see Figure 3 As shown, in one example of a sandwich architecture, the electronic device 200 also includes a middle plate 201 located within an annular frame 202 surrounding the middle plate 201, which provides an assembly space for the various structural components of the electronic device 200.

[0085] The electronic device 200 also includes a support backplate 203 for supporting the display screen 204 and assembling the display screen 204. The display screen 204 can be adhered to one side of the support backplate 203 via an adhesive layer. The display screen 204 and the support backplate 203 together form a display module 205. The display module 205 and the back cover 20 can be respectively disposed on opposite sides of the bezel 202 along the thickness direction (z direction).

[0086] The frame 202 and the back cover 20 can be separate structural components. The back cover 20 can be assembled with the frame 202 through an adhesive layer. The side of the support back plate 203 facing away from the display screen 204 can be assembled with the frame 202 through an adhesive layer to fix the display module 205 to the frame 202. Along the thickness direction (z direction) of the electronic device, there can be a gap between the support back plate 203 and the middle plate 201, so that the support back plate 203, the frame 202 and the middle plate 201 form a receiving space for accommodating the various structural components of the electronic device 200, such as the battery 70 and various electronic components 208 as shown in the figure.

[0087] Using the sandwich architecture described above, the thickness of the entire electronic device is approximately 6.6mm. This relatively thick design results in a relatively heavy device, which is not conducive to meeting the design requirements for a thinner and lighter electronic device.

[0088] To further reduce the thickness of electronic devices, in examples of unibody architectures, the electronic device may not include a mid-plate; the back cover and frame can be integrally molded, making the housing a single structural component. The frame and back cover enclose a receiving space with an opening at one end.

[0089] The display screen can be attached to one side of the supporting back plate via an adhesive layer. The display screen and the supporting back plate together form a display module. The side of the supporting back plate facing away from the display screen can be assembled with the side of the frame away from the back cover via an adhesive layer, thus fixing the display module to the frame. The display module can close the receiving space enclosed by the frame and the back cover, so that the supporting back plate, frame, and back cover together form a closed receiving space.

[0090] Using the aforementioned integrated architecture, the thickness of the entire electronic device is approximately 6.3mm. While relatively thinner than the sandwich architecture, this still falls short of current demands for slimness and lightness in electronic devices, requiring further reduction in thickness. Furthermore, in integrated architectures, to ensure the structural strength of the casing, a plastic support frame is typically added to the inner circumferential side of the frame, resulting in a heavier electronic device.

[0091] Based on this, this application provides an electronic device and a screen assembly. The screen assembly includes a display screen and a mid-frame support member. The display screen is disposed in a receiving groove on one side of the mid-frame support member, and the side of the display screen facing the mid-frame support member is in contact with the bottom surface of the receiving groove, thereby achieving assembly and fixation of the display screen and the mid-frame support member. The display screen and the mid-frame support member are assembled using an open-cell design. When assembling the electronic device, the side of the mid-frame support member away from the display screen is assembled with the back cover. The mid-frame support member and the back cover form a receiving space. The mid-frame support member may include a frame or be fitted with a frame, thus achieving the assembly of the display screen, frame, and back cover. That is, the mid-frame support member can support the display screen and realize the assembly of the display screen. The mid-frame support member can also provide an assembly space for the various structural components of the electronic device. Compared with electronic devices in related technologies, there is no need to set up a support back plate for supporting the display screen, realizing a bezel-less design, making the entire screen assembly thinner and lighter. It can also eliminate the need for the adhesive layer between the back panel and the middle plate (middle frame support) and the gap between the back panel and the middle plate (middle frame support), further reducing the thickness and weight of the screen assembly, thereby reducing the thickness of the entire electronic device, reducing the weight of the electronic device, and realizing the design of a thin and light electronic device.

[0092] Figure 4 for Figure 1 A schematic diagram of the disassembled structure of electronic devices in China.

[0093] See Figure 4 As shown, the electronic device 100 includes a screen assembly 102, which includes a display screen 30 and a mid-frame support 40. The display screen 30 is mounted on one side of the mid-frame support 40, such as the display screen 30 being located on one side of the mid-frame support 40 along the thickness direction (z direction).

[0094] The back cover 20 is located on the side of the middle frame support 40 that faces away from the display screen 30, that is, the back cover 20 and the display screen 30 can be located on opposite sides of the middle frame support 40 along the thickness direction (z direction).

[0095] Figure 5 for Figure 1 A partial cross-sectional structural diagram of the electronic device along plane AA.

[0096] Combination Figure 5 As shown, the back cover 20 can be assembled onto the side of the mid-frame support 40 opposite to the display screen 30. For example, the back cover 20 can be assembled with the mid-frame support 40 by adhesive bonding. Of course, in some other examples, the back cover 20 and the mid-frame support 40 can also be fixed together by welding, snap-fit ​​connection, threaded connection, interference fit, etc.

[0097] The back cover 20 and the middle frame support 40 can form an accommodating space 103, in which the various structural components of the electronic device 100 can be placed, ensuring the simplicity and aesthetics of the electronic device 100 and providing isolation and protection for the various structural components.

[0098] In some examples, such as Figure 4 and Figure 5 As shown, the frame 10 and the middle frame support 40 can be independent structural components, that is, the frame 10 and the middle frame support 40 are two separable structural components. The frame 10 can be assembled onto the middle frame support 40, and the frame 10 is arranged around the outside of the middle frame support 40. For example, the frame 10 can be fixedly assembled with the middle frame support 40 by means of welding connection, snap connection, threaded connection, interference fit and adhesive connection.

[0099] In the example where the bezel 10 and the mid-frame support 40 are two independent structural components, the screen assembly 102 may include the bezel 10. In actual assembly, the display 30, the mid-frame support 40 and the bezel 10 can be assembled together to form the screen assembly, and then the screen assembly 102 and the back cover 20 can be assembled to form the electronic device 100.

[0100] Alternatively, screen assembly 102 may not include bezel 10. In actual assembly, display screen 30 and mid-frame support 40 can be assembled together to form screen assembly, and then screen assembly 102, back cover 20 and bezel 10 can be assembled to form electronic device 100.

[0101] For example, continue to refer to Figure 4 As shown, the electronic device 100 may also include a main control board 60 and a battery 70. The main control board 60 and the battery 70 may be located in the aforementioned accommodating space 103. For example, the main control board 60 and the battery 70 may be mounted and fixed on the side of the mid-frame support 40 away from the display screen 30.

[0102] The main control board 60 may include a processor, controller, memory, etc. (not shown in the figure). The processor may include one or more interfaces, which can be used to connect a charger to charge the electronic device 100, and can also be used to realize data transmission between the electronic device 100 and external devices, such as connecting headphones, projection devices, etc.

[0103] The electronic device 100 may also include a charging management module and a power management module (not shown in the figure), which may also be fixed within the aforementioned accommodating space.

[0104] The charging management module receives charging input from a charger, which can be either a wireless charger or a wired charger. In some wired charging examples, the charging management module receives charging input from the wired charger via an interface. In some wireless charging embodiments, the charging management module receives wireless charging input via the wireless charging coil of the electronic device 100. The charging management module can charge the battery 70 and can also supply power to the electronic device 100 via the power management module.

[0105] The power management module is used to connect the battery 70, the charging management module, and the processor, etc. The power management module receives input from the battery 70 and / or the charging management module to power the processor, memory, display 30, camera, etc. The power management module can also be used to monitor parameters such as battery 70 capacity, battery cycle count, and battery health status (leakage current, impedance).

[0106] In some examples, the power management module may be located within the processor of the main control board 60. In other examples, the power management module and the charging management module may be located in the same device.

[0107] The electronic device 100 may also include other types of structural components, such as functional modules and other types of electronic devices, to enhance the various functions of the electronic device 100. For example, the electronic device 100 may also include modules and electronic devices such as camera modules, speakers, microphones, communication modules, and sensors. All of the above-mentioned structural components can be accommodated within the accommodating space.

[0108] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements.

[0109] The following example illustrates the structure and assembly method of the mid-frame support 40 and the display screen 30, taking the bezel 10 and the mid-frame support 40 as two independent structural components, with the screen assembly 102 excluding the bezel 10.

[0110] Figure 6 for Figure 4 A schematic diagram of a split structure for a mid-screen component.

[0111] See Figure 6As shown, a receiving groove 40a can be formed on one side of the mid-frame support member 40. The display screen 30 is disposed in the receiving groove 40a. The bottom surface of the receiving groove 40a can be a whole plane. The side of the display screen 30 facing the mid-frame support member 40 can be attached to the bottom surface of the receiving groove 40a. For example, the side of the display screen 30 facing the mid-frame support member 40 can be attached to the bottom surface of the receiving groove 40a through an adhesive layer, so as to realize the assembly and fixation of the display screen 30 and the mid-frame support member 40, and realize the open-cell assembly of the display screen 30 and the mid-frame support member 40.

[0112] When assembling the aforementioned electronic device 100, the mid-frame support 40 can be fitted inside the frame 10 (see reference). Figure 5 As shown, the middle frame support 40 is assembled with the back cover 20 on the side opposite to the display screen 30. The middle frame support 40 and the back cover 20 form a receiving space 103, thus realizing the assembly of the display screen 30, the frame 10 and the back cover 20.

[0113] The mid-frame support 40 serves to support the display screen 30 and facilitate its assembly. The display screen 30 is directly attached to one side of the mid-frame support 40, allowing for an open-cell assembly between the display screen 30 and the mid-frame support 40. This enables the display screen 30 to be assembled with the bezel 10, back cover 20, and other components. Eliminating the need for a separate backplate for the display screen allows for a bezel-less design, resulting in a thinner and lighter screen assembly 102. This, in turn, reduces the overall thickness and weight of the electronic device 100, facilitating its slim and lightweight design.

[0114] The mid-frame support 40 can also provide an assembly space for the various structural components of the electronic device 100. The various structural components of the electronic device 100 can be assembled on the side of the mid-frame support 40 facing away from the display screen 30. Compared with the electronic devices in the related technologies, the mid-frame support 40 can realize the function of the middle plate in the related technologies. The display screen 30 is directly attached to one side of the mid-frame support 40. It can also eliminate the adhesive layer between the support back plate and the middle plate (mid-frame support 40) and the gap between the support back plate and the middle plate (mid-frame support 40), further reducing the thickness and weight of the screen assembly 102, making the electronic device 100 thinner and lighter, and realizing the lightweight design of the electronic device 100.

[0115] For example, the thickness of the mid-frame support 40 can be 5.3mm to 5.5mm, and the overall thickness of the screen assembly is relatively thin, which can effectively achieve the design of reducing the thickness of electronic devices.

[0116] The screen assembly 102, together with the frame 10 and the back cover 20, forms an electronic device 100 (see reference). Figure 4 The thickness of the electronic device 100 (as shown) can be 5.8mm to 6.0mm. Compared with the integrated shell architecture and sandwich architecture of electronic devices in related technologies, the thickness is reduced by about 0.3mm to 0.8mm, and the weight is reduced by about 3% to 12%. This allows the electronic device 100 to achieve an ultra-thin design and significantly reduces the weight of the electronic device 100, thus achieving a lightweight and thin design for the electronic device 100.

[0117] See Figure 5 As shown, the display screen 30 may include a display panel 31, see [link / reference]. Figure 6 As shown, the display screen 30 may also include a circuit board 32. The display panel 31 can be electrically connected to the main control board through the circuit board 32, so that the main control board can control the display panel 31 to realize the display function. The display panel 31 is disposed in the receiving groove 40a on one side of the middle frame support member 40.

[0118] Figure 7 for Figure 6 A partial cross-sectional structural diagram of the assembly of the middle screen component and the main control board. Figure 8 for Figure 6 A magnified view of the middle screen component at the notch structure.

[0119] See Figure 7 As shown, the main control board 60 is located in the accommodating space formed by the middle frame support 40 and the rear cover 20 (not shown in the figure), such as the main control board 60 being assembled on the side of the middle frame support 40 facing away from the display screen 30.

[0120] To achieve electrical connection between the display panel 31 and the main control board 60 via circuit board 32, combined with Figure 6 As shown, one side edge of the mid-frame support member 40 may have a notch structure 423. For example, a notch structure 423 may be provided on one side edge of the mid-frame support member 40 along the width direction (x direction). The notch structure 423 may penetrate the mid-frame support member 40 in the thickness direction (z direction).

[0121] Of course, in some other examples, a notch structure 423 can also be provided on one edge of the middle frame support 40 along the length direction (y direction). The specific configuration can be selected according to the layout requirements of the display screen 30 and the various structural components within the accommodating space.

[0122] See Figure 8 As shown, one end of the circuit board 32 can be electrically connected to the display panel 31, and a portion of the circuit board 32 can be accommodated within the notch structure 423, in conjunction with... Figure 7As shown, the other end of the circuit board 32 can extend to the side of the mid-frame support 40 facing away from the display panel 31. This allows the other end of the circuit board 32 to be electrically connected to the main control board 60 mounted on the side of the mid-frame support 40 facing away from the display panel 31, thus realizing the electrical connection between the display panel 31 and the main control board 60 and ensuring the electrical conduction of the display panel 31.

[0123] By using the notch structure 423 to allow the other end of the circuit board 32 to wrap around the side of the middle frame support 40 facing away from the display panel 31, compared to connecting the circuit board 32 to the main control board 60 by wrapping it around the side of the middle frame support 40 or the side of the frame 10, the circuit board 32 can avoid affecting the assembly of the middle frame support 40 and the frame 10, and ensure that the circuit board 32 is not exposed. The layout is compact and has better aesthetics.

[0124] For example, a notch structure 423 can be provided only on one side of the mid-frame support member 40, which helps to ensure the strength of the mid-frame support member 40, thereby ensuring the reliability of the screen assembly and electronic devices, and allows the mid-frame support member 40 to provide a larger mounting hole diameter, so as to facilitate the assembly of various structural components on it.

[0125] In this embodiment, the relative positions of the main control board 60 and the notch structure 423 are not limited. For example, along the width direction (x direction) (or along the length direction (y direction) of the electronic device, the notch structure 423 and the main control board 60 can be located on opposite sides of the middle frame support member 40. One end of the circuit board 32 is connected to the display panel 31, and the circuit board 32 can span the accommodating space along the width direction, so that the other end of the circuit board 32 is connected to the main control board 60.

[0126] Alternatively, in some examples, the notch structure 423 and the main control board 60 may be located on the same side of the mid-frame support 40 along the width direction (x-direction) or length direction (y-direction) of the electronic device. The relative position of the main control board 60 and the notch structure 423 can be selected and set according to the layout requirements within the accommodating space.

[0127] Circuit board 32 can be a flexible printed circuit (FPC). Alternatively, circuit board 32 can also be a rigid circuit board, for example, a printed circuit board (PCB). Of course, in some examples, circuit board 32 can also be partly a flexible circuit board and partly a rigid circuit board.

[0128] In some examples, the notch structure 423 may extend to one outer surface of the middle frame support 40 (the side facing away from the receiving space), for example... Figure 8As shown, the mid-frame support member 40 has the notch structure 423 on one outer surface along the width direction (x direction). The circuit board 32 can pass through the notch structure 423 from the side of the mid-frame support member 40, so that part of the circuit board 32 is inserted and accommodated in the notch structure 423, and the other end of the circuit board 32 can be wrapped around to the side of the mid-frame support member 40 away from the display panel 31, which facilitates the assembly of the display screen 30 and the mid-frame support member 40.

[0129] Furthermore, unlike the notch structure 423 which does not extend to the outer surface of the mid-frame support member 40, a portion of the circuit board 32 can be accommodated and inserted through the notch structure 423 from the side, allowing the other end of the circuit board 32 to wrap around to the side of the mid-frame support member 40 away from the display panel 31. The size of the notch structure 423 only needs to accommodate the size of the portion of the circuit board 32 corresponding to the notch structure 423 (i.e., the portion of the circuit board 32 inserted and accommodated within the notch structure 423), which helps to reduce the size of the notch structure 423, improve the strength of the mid-frame support member 40, enhance the reliability of the screen assembly and electronic devices, and allow the mid-frame support member 40 to provide more assembly space, facilitating the assembly of various structural components of the electronic devices.

[0130] For example, the shape, quantity, and size of the portion of the circuit board 32 housed within the notch structure 423 can be designed to meet the functional requirements of the circuit board 32 while reducing the size of that portion of the circuit board 32 and the notch structure 423.

[0131] If the circuit board 32 can be divided into multiple spaced sections, multiple notch structures 423 can be provided on the mid-frame support 40 (see reference). Figure 9 As shown, multiple notch structures 423 can be spaced apart. For example, if a notch structure 423 is provided on one side of the middle frame support member 40 along the width direction, multiple notch structures 423 can be spaced apart along the length direction (y direction). This makes each notch structure 423 smaller, and the adjacent notch structures 423 are spaced apart by a portion of the middle frame support member 40. Compared with providing a relatively large notch structure on the middle frame support member 40, this increases the strength of the middle frame support member 40.

[0132] In the example where the bezel 10 and the mid-frame support 40 are two independent structural components, when assembling the screen assembly 102 with the bezel 10 (refer to...) Figure 5 As shown, the frame 10 surrounds the middle frame support 40, and the inner surface of the frame 10 (the side facing the receiving space) can be opposite to the outer surface of the middle frame support 40. The frame 10 can shield and protect the circuit board 32 passing through the notch structure 423, so that the circuit board 32 is not exposed, thus protecting the circuit board 32 and improving the aesthetics.

[0133] By separating the bezel 10 and the mid-frame support 40 into two structural components, and extending the notch structure 423 to the outer surface of the mid-frame support 40, the assembly of the display screen 30, the mid-frame support 40, and the bezel 10 can be facilitated. In actual assembly, the display panel 31 of the display screen 30 is first placed within the receiving groove 40a of the mid-frame support 40, and part of the circuit board 32 of the display screen 30 is inserted through the notch structure 423 from the side. The other end of the circuit board 32 is wrapped around the side of the mid-frame support 40 facing away from the display panel 31. Then, the bezel 10 is fitted over the mid-frame support 40. This assembly method is simple and convenient, improving assembly efficiency.

[0134] Figure 8a for Figure 4 A schematic diagram of the assembly process of electronic equipment.

[0135] For example, in actual assembly, see Figure 8a As shown, the display screen 30 can be placed in the receiving groove 40a of the mid-frame support 40. By folding or other means, a portion of the circuit board 32 can be inserted from the side into the notch structure 423, with the other end of the circuit board 32 positioned on the side of the mid-frame support 40 away from the display panel. The display screen 30 can be at least partially fixed and adhered to the receiving groove by means of adhesive, so that the bottom surface of the groove 40a of the mid-frame support 40 is in contact with the display screen 30. The other end of the circuit board is electrically connected to the main control board. Then, the frame 10 is fitted over the mid-frame support 40, assembling the frame 10, the mid-frame support 40, and the display screen 30. Finally, the other structural components of the electronic device are assembled, and the back cover is assembled, completing the assembly of the electronic device.

[0136] Figure 9 for Figure 6 A schematic diagram of the middle frame support component from one perspective.

[0137] For example, see Figure 9 As shown, the middle frame support 40 may include a middle plate 41 and a side frame 42, wherein the middle plate 41 may be a plate-like structural member, and the side frame 42 may be a frame-like structural member. For example, the middle plate 41 may be a flat plate structure with a rectangular outer contour, and the side frame 42 may be a ring structure with a rectangular outer contour. The side frame 42 is arranged around the middle plate 41.

[0138] The side frame 42 may include opposing inner side surface 42a and outer side surface 42b. The inner side surface 42a of the side frame 42 can be fixedly assembled with the middle plate 41, and the outer side surface 42b of the side frame 42 can be the outer surface of the middle frame support member 40. The notch structure 423 can extend to the outer side surface 42b of the side frame 42, that is, the notch structure 423 is present at least on the outer side surface 42b of the side frame 42. When the frame 10 and the middle frame support member 40 are assembled, the frame 10 can be fixedly assembled with the side frame 42, and the inner surface of the frame 10 can be fitted against the outer side surface 42b of the side frame 42.

[0139] For example, the side frame 42 and the middle plate 41 can be integrally formed, making the middle frame support 40 a one-piece structural component. Of course, in some other examples, the side frame 42 and the middle plate 41 can also be formed independently, and the side frame 42 and the middle plate 41 can be assembled together by means of adhesive connection, welding connection, snap-fit ​​connection, threaded connection, etc.

[0140] Figure 10 for Figure 9 A partial cross-sectional structural diagram of the middle frame support component.

[0141] For example, see Figure 10 As shown, the middle plate 41 may include a first surface 411 and a second surface 412 opposite to each other, such that the first surface 411 and the second surface 412 are opposite to each other in the thickness direction (z direction), and the first surface 411 and the second surface 412 are respectively located on opposite sides of the middle plate 41 in the thickness direction (z direction).

[0142] The side frame 42 may include a first frame portion 421, which may protrude from the first surface 411 of the middle plate 41, so that the first frame portion 421 and the middle plate 41 can form a receiving groove 40a, in which the display screen is accommodated, and one side of the display screen can be attached to the first surface 411.

[0143] In some examples, the display screen can be completely housed within the receiving slot 40a, and in the thickness direction (z-direction), the display surface of the display screen (the side facing away from the middle plate 41) can be flush with the end face 421a of the first frame portion 421 facing away from the middle plate 41. The screen assembly is assembled with a bezel, which surrounds the outer periphery of the side frame 42, and the end face of the bezel in the thickness direction (z-direction) can be flush with the end face 421a of the first frame portion 421 facing away from the middle plate 41.

[0144] Alternatively, in some examples, the display screen may be partially housed within the receiving groove 40a, while a portion of the display screen 30 may be located outside the receiving groove 40a along the thickness direction (z direction).

[0145] Figure 11 for Figure 4A schematic diagram of another split structure for the middle screen component.

[0146] For example, see Figure 11 As shown, the display screen 30 may also include a cover plate 33, which is located on the side of the display panel 31 away from the middle plate 41. Along the thickness direction (z direction), the cover plate 33 may be located on the outermost side of the entire display screen 30, and the cover plate 33 can protect the display panel 31 and other components of the display screen 30.

[0147] For example, the cover plate 33 can be a glass cover plate. Of course, in some other examples, the cover plate 33 can also be other types of plate-shaped structural members such as plastic.

[0148] The cover plate 33 and the display panel 31 can be bonded together. Of course, in some other examples, the cover plate 33 and the display panel 31 can also be bonded together by other methods such as heat pressing.

[0149] The display screen 30 may also include a functional film layer 34, which may include, but is not limited to, a light guide layer, a diffusion layer, a reflective layer, a brightness enhancement film, etc. The functional film layer 34 can be used to enhance the display function of the display screen 30. The functional film layer 34 can be a single layer, or it can be multiple layers stacked together. The functional film layer 34 can be located on the side of the display panel 31 opposite to the cover plate 33, that is, along the thickness direction (z direction). The cover plate 33, the display panel 31, and the functional film layer 34 can be arranged sequentially.

[0150] Figure 12 for Figure 4 A partial cross-sectional view of the middle screen component.

[0151] For example, see Figure 12 As shown, the functional film layer 34 and display panel 31 of the display screen 30 can be accommodated in the receiving groove 40a, and the cover plate 33 can be located outside the receiving groove 40a. That is, along the thickness direction (z direction), the height of the cover plate 33 can be higher than the height of the first frame portion 421. The cover plate 33 can be mounted on the end face of the first frame portion 421 away from the middle plate 41, which facilitates the assembly of the display screen 30 and the middle frame support member 40, reduces the assembly difficulty, and improves the integrity and aesthetics of the assembled middle frame support member 40, thereby ensuring the aesthetics of the electronic device.

[0152] The bezel 10 surrounds the outer perimeter of the side frame 42. One end face of the bezel 10 in the thickness direction (z direction) can be flush with the side of the cover plate 33 facing away from the display panel 31. The side of the cover plate 33 facing away from the display panel 31 can be the display surface of the display screen 30.

[0153] In some examples, the display screen 30 may also include a light source (not shown in the figure) that emits light. The light source may be a light-emitting structural component such as a light strip, and there may be one or more light sources. The light source may be mounted on the mid-frame support 40, for example, the light source may be mounted together with a functional film layer, etc., and fixed in the receiving groove 40a. Alternatively, the light source may not be assembled with other structural components of the display screen 30, but may be mounted separately on the mid-frame support 40.

[0154] When assembling the display screen 30 into the receiving groove 40a of the mid-frame support 40, the light source and functional film layer 34 can be assembled together, and then the display panel 31, circuit board 32, functional film layer 34, cover plate 33, etc. can be assembled and placed in the receiving groove 40a of the mid-frame support 40. Alternatively, the display panel 31, circuit board 32, functional film layer 34, cover plate 33, etc. can be assembled together and placed in the receiving groove 40a, and the light source can be assembled separately on the mid-frame support 40.

[0155] Figure 13 for Figure 9 A structural schematic diagram of the middle frame support component from another perspective.

[0156] Combination Figure 12 and Figure 13 As shown, the side frame 42 may further include a second frame portion 422, which may protrude from the second surface 412 of the middle plate 41. The second frame portion 422 and the middle plate 41 may also form a receiving cavity, which can serve as part of the receiving space formed by the middle frame support member 40 and the rear cover, thereby expanding the receiving space. While ensuring the thickness of the electronic device is reduced, this facilitates increasing the volume of the receiving space, making it easier to arrange the various structural components of the electronic device within the receiving space.

[0157] The rear cover 20 can be fitted onto the end face of the second frame 422 opposite to the middle plate 41 (see reference). Figure 5 As shown, the second frame portion 422, the middle plate 41, and the rear cover 20 can form an accommodating space, that is, the inner side of the second frame portion 422, the second surface 412 of the middle plate 41, and the inner surface of the rear cover 20 together form an accommodating space 103. The frame 10 surrounds the outer periphery of the side frame 42, and the other end face of the frame 10 in the thickness direction (z direction) can be flush with the side of the rear cover 20 facing away from the middle plate 41.

[0158] In some examples, the mid-frame support 40 may not include the side frame 42, such as only including the mid-plate 41. The frame 10 is provided around the mid-frame support 40, and a portion of the frame 10 may protrude from the first surface 411 of the mid-plate 41, such that a portion of the frame 10 and the mid-frame support 40 form a receiving groove 40a, which is located on one side of the mid-plate 41.

[0159] In the example where the mid-frame support 40 includes a side frame 42, the side frame 42 may not include a second frame portion 422, such as the side frame 42 may only include a first frame portion 421. The frame 10 is disposed around the mid-frame support 40, and a portion of the frame 10 may protrude from the second surface 412 of the mid-plate 41. The rear cover 20 may be assembled with the frame 10, so that the frame 10, the mid-frame support 40 and the rear cover 20 form an accommodating space.

[0160] See also Figure 13 As shown, the second surface 412 of the middle plate 41 may have a plurality of mounting slots 413, and the various structural components of the electronic device can be correspondingly accommodated and assembled in the respective mounting slots 413. For example, structural components such as batteries, main control boards, charging management modules, power management modules, cameras, and speakers can all be correspondingly assembled in the mounting slots 413.

[0161] It should be noted that the position, shape, and quantity of the assembly slot 413 can be selected and set according to the layout, shape, and quantity of the corresponding structural components.

[0162] In some examples, the middle plate 41 may also have a mounting slot (not shown in the figure), which can penetrate the middle plate 41 in the thickness direction (z direction). The middle frame support 40 may also include a reinforcing member 50, which can be accommodated in the mounting slot.

[0163] The reinforcing member 50 can be fixedly connected to the side wall of the assembly slot to achieve assembly and fixation of the reinforcing member 50 and the middle plate 41. For example, the reinforcing member 50 and the middle plate 41 can be assembled and fixed together by welding, bonding, threading, and snap-fit ​​connection.

[0164] The sidewall of the mounting slot can be arranged around the reinforcing member 50, so that the reinforcing member 50 and the sidewall of the mounting slot can together form a receiving compartment 50a. This receiving compartment 50a can serve as a battery compartment for accommodating batteries for assembling electronic devices. For example, the reinforcing member 50 may include two opposing sides along the thickness direction (z direction), one of which, together with the sidewall of the mounting slot, forms the receiving compartment 50a, and the battery can be assembled and fixed to this side by means of adhesive bonding or other methods.

[0165] One side of the reinforcing member 50 can be flush with the first surface of the middle plate 41, together serving to support the display screen, and part of the display screen can be attached to one side of the reinforcing member 50.

[0166] For example, the strength of the molding material of the reinforcing member 50 can be greater than the strength of the molding material of the middle plate 41, so that the overall strength of the reinforcing member 50 can be greater than the overall strength of the middle plate 41 or the middle frame support member 40. This helps to improve the assembly stability and reliability of the battery, and thus improve the assembly stability and reliability of the entire electronic device.

[0167] The thickness of the reinforcing member 50 can be less than the thickness of the middle plate 41. While ensuring that the battery assembly requirements are met, the thickness of the reinforcing member 50 in the battery assembly area is reduced, which increases the space of the accommodating compartment 50a in the thickness direction (z direction), thereby facilitating further reduction of the thickness of the electronic device.

[0168] For example, the thickness of the reinforcing member 50 can be in the range of 0.2mm to 0.4mm. While ensuring that the reinforcing member 50 has good strength, the thickness of the reinforcing member 50 is thinner, which is more conducive to the thinning of electronic devices.

[0169] In some examples, the reinforcing member 50 can be made of aluminum, such as high-strength aluminum. Alternatively, the reinforcing member 50 can be made of magnesium, such as high-strength magnesium. Or, the reinforcing member 50 can be made of stainless steel, etc. This provides high strength, which is beneficial for meeting the strength requirements and thinning requirements of electronic devices.

[0170] Alternatively, in some examples, the reinforcing member 50 may be formed from a combination of materials such as aluminum, magnesium, and stainless steel. Alternatively, the reinforcing member 50 may also be formed from other high-strength materials.

[0171] In some examples, the mid-frame support 40 can be made of aluminum alloy, which has high strength, ensuring support for the display screen, etc., and also makes the mid-frame support 40 thinner and lighter. This facilitates further reduction of the thickness and weight of the electronic device 100.

[0172] In one example, the mid-frame support 40 can be made of aluminum alloy, the reinforcing member 50 can be made of high-strength aluminum, high-strength magnesium, or stainless steel, and the frame 10 can be made of plastic. The mid-frame support 40 has high strength, allowing the assembled electronic device 100 to be thinner to 5.8mm–6.0mm, resulting in a weight reduction of approximately 3% compared to a sandwich architecture.

[0173] Alternatively, in some examples, the mid-frame support 40 can be made of magnesium alloy to further reduce the weight of the mid-frame support 40 while ensuring that high strength requirements are met.

[0174] In one example, the mid-frame support 40 can be made of magnesium alloy, the reinforcing member 50 can be made of high-strength aluminum, high-strength magnesium, or stainless steel, and the frame 10 can be made of plastic. The thickness of the assembled electronic device 100 can be reduced to 5.8mm to 6.0mm, and the weight can be further reduced, for example, by about 12% compared to the sandwich architecture.

[0175] Alternatively, in some examples, the molding material of the mid-frame support 40 can be a combination of several materials such as aluminum alloy and magnesium alloy.

[0176] In some examples, the molding material of the border 10 can be plastic, and the border 10 can be a plastic part, which gives the border 10 a high degree of design flexibility in terms of color, shape and other appearance effects.

[0177] Alternatively, in some examples, the frame 10 can be made of metal or metal alloy; for example, the frame 10 can be made of aluminum alloy. This gives the frame 10 a metallic sheen, which helps to optimize the appearance and sophistication of the electronic device 100.

[0178] In one example, the mid-frame support 40 can be made of aluminum alloy, the reinforcing member 50 can be made of high-strength aluminum, high-strength magnesium, or stainless steel, and the frame 10 can be made of aluminum alloy. The thickness of the assembled electronic device 100 can be reduced to 5.8mm to 6.0mm. The overall strength of the component formed by the mid-frame support 40 and the frame 10 is high, which helps to improve the stability and reliability of the entire electronic device 100 and optimize the appearance.

[0179] Alternatively, in some examples, the molding material of the border 10 can be a combination of several of the following: plastic, metal, and metal alloy.

[0180] Understandably, the molding materials of the frame 10, the middle frame support 40, and the reinforcement 50 can be selected and matched according to actual needs. For example, the molding material of the frame 10 can be any of aluminum alloy, plastic, etc., the molding material of the middle frame support 40 can be any of aluminum alloy, magnesium alloy, etc., and the molding material of the reinforcement 50 can be any of high-strength aluminum, high-strength magnesium, and stainless steel, etc.

[0181] For example, in the case where the frame 10 is made of aluminum alloy, the middle frame support 40 can be made of magnesium alloy.

[0182] In one example, the mid-frame support 40 can be made of magnesium alloy, the reinforcing member 50 can be made of high-strength aluminum, high-strength magnesium, or stainless steel, and the frame 10 can be made of aluminum alloy. The thickness of the assembled electronic device 100 can be reduced to 5.8mm to 6.0mm. Compared to the frame 10 and mid-frame support 40 being made of aluminum alloy, the weight of the electronic device 100 is further reduced, for example, by about 10% compared to the sandwich architecture solution.

[0183] It is understandable that the above example illustrates the assembly of the display screen 30 and the mid-frame support 40 using the bezel 10 and the mid-frame support 40 as two independent structural components. In some other examples, the screen assembly 102 may include the bezel 10, and the mid-frame support 40 and the bezel 10 may be an integrated structural component.

[0184] Figure 14 This is a schematic diagram of the disassembled structure of another electronic device provided in an embodiment of this application.

[0185] For example, see Figure 14 As shown, the screen assembly 102 includes a bezel 10, a mid-frame support 40, and a display screen 30. The bezel 10 and the mid-frame support 40 can be integrated structural components, meaning that the bezel 10 and the mid-frame support 40 are integrally formed into a single structural component. The bezel 10 can be arranged around the outside of the mid-frame support 40, so that the mid-frame support 40 is fitted inside the bezel 10.

[0186] The display screen 30 can be mounted on one side of the integrated structure formed by the mid-frame support 40 and the frame 10. The back cover 20 can be mounted on the side of the integrated structure away from the display screen 30, for example, along the thickness direction (z direction) of the electronic device 100. The back cover 20 and the display screen 30 are respectively disposed on opposite sides of the integrated structure.

[0187] The back cover 20, the mid-frame support 40, and the side frame 10 form an integrated structural component that encloses a receiving space (not shown in the figure), within which various structural components of the electronic device 100 can be housed. For example, the main control board 60 and the battery 70 of the electronic device 100 can all be housed within this receiving space.

[0188] Figure 15 for Figure 14 A schematic diagram of the partial split structure of the middle screen component.

[0189] See Figure 15 As shown, a receiving groove 40a can be formed on one side of the mid-frame support member 40, and the display screen 30 is disposed in the receiving groove 40a. The side of the display screen 30 facing the mid-frame support member 40 can be attached to the bottom surface of the receiving groove 40a. The shape and structure of the receiving groove 40a, as well as the assembly position and assembly method between the receiving groove 40a and the display screen 30, can be referred to the above text and will not be repeated here.

[0190] The structure of the middle frame support 40 can be the same as in the example above where the middle frame support 40 and the frame 10 are two independent structural components. For example, the middle frame support 40 may include a side frame and a middle plate, with the side frame surrounding the middle plate. The side frame may include a first frame portion and a second frame portion, with the first frame portion protruding from the first surface of the middle plate, and the first frame portion and the middle plate forming a receiving groove. The second frame portion may protrude from the second surface of the middle plate. Alternatively, the middle frame support 40 may not include a side frame or a second frame portion; specific implementation methods can be found above and will not be repeated here.

[0191] The back cover 20 and the display screen 30 can be assembled with the mid-frame support 40 respectively. The assembly position and method of the back cover 20, display screen 30 and mid-frame support 40 can be the same as in the example above where the mid-frame support 40 and the frame 10 are two independent structural components. For example, the display screen 30 is attached to the first surface of the mid-plate. The back cover 20 can be assembled on the end face of the second frame part away from the mid-plate, and the second frame part, the mid-plate and the back cover form an accommodating space. The specific implementation method can be referred to above, and will not be repeated here.

[0192] The display screen 30 can be completely accommodated within the receiving groove 40a of the mid-frame support 40. Alternatively, the display screen 30 can be partially located outside the receiving groove 40a. For example, the cover plate of the display screen 30 can be fitted onto the end face of the first frame portion away from the mid-frame. After the display screen 30 is assembled with the mid-frame support 40 and the frame 10, the side of the cover plate away from the receiving space and one end face of the frame can be flush. Specific implementation methods can be found above and will not be repeated here.

[0193] The mid-frame support 40 may also include a reinforcing member, which, together with the sidewall of the mounting slot on the mid-plate, can form a receiving compartment for accommodating the battery. The structure, molding material, thickness, mounting position and method of the reinforcing member with the mid-plate can be referred to the above, and will not be repeated here.

[0194] The middle frame support 40 and the frame 10 are an integral structural component. The molding material of the middle frame support 40 and the frame 10 can be the same, or in some examples, the molding materials of the two can be different. The specific materials and thicknesses can be the same as in the example above where the middle frame support 40 and the frame 10 are two independent structural components. Please refer to the above.

[0195] Figure 16 for Figure 14 A partial cross-sectional structural diagram of the middle frame support component.

[0196] Combination Figure 15 and Figure 16As shown, a notch structure 423 is present on one side edge of the mid-frame support member 40. The shape, number, and relative position of the notch structure 423 to the main control board are the same as in the example above where the mid-frame support member 40 and the frame 10 are two independent structural members, and will not be repeated here.

[0197] The display screen 30 may include a display panel 31 and a circuit board 32 (see reference). Figure 14 As shown, the display panel 31 is located within the receiving groove, and one end of the circuit board 32 is electrically connected to the display panel 31. Part of the circuit board 32 can be inserted and accommodated within the notch structure (not shown in the figure), and the other end of the circuit board 32 can extend to the side of the middle frame support 40 facing away from the display panel, so that the other end of the circuit board can be electrically connected to the main control board mounted on the side of the middle frame support 40 facing away from the display panel, ensuring the electrical conduction of the display panel.

[0198] The electronic device may also include a fastener 90 (continue to refer to) Figure 14 As shown, the fastener 90 is located on the side of the middle frame support 40 away from the display panel 31. Part of the circuit board 32 passes through the notch structure and can be fixed by the fastener 90.

[0199] The notch structure can be located on the outer surface of the middle frame support member 40, such as on the outer surface of the side frame, that is, the notch structure can extend to the outer surface of the middle frame support member 40. The specific location and implementation method can also be referred to the above. Alternatively, the notch structure may not extend to the outer surface of the middle frame support member 40. For example, the notch structure can be located on the middle plate of the middle frame support member 40, or the notch structure can be partially located on the middle plate and partially located on the side frame of the middle frame support member 40. There is a certain distance between the notch structure and the outer side surface of the side frame (i.e., the outer surface of the middle frame support member 40), and there is a portion of the side frame between the notch structure and the outer side surface of the side frame.

[0200] Figure 17 for Figure 14 A schematic diagram showing the disassembled structure of the middle screen component and the display screen.

[0201] In the example where the mid-frame support 40 and the side frame 10 are integral structural components, the opening size of the notch structure is reduced. See [link / reference]. Figure 17 As shown, the circuit board 32 of the display screen may include a flexible connecting plate 321 and a circuit board 322. The flexible connecting plate 321 may include a flexible circuit board. The circuit board 322 may include a flexible circuit board, or the circuit board 322 may include a printed circuit board.

[0202] The circuit board 322 can be disposed on the side of the mid-frame support 40 facing away from the display panel 31, and the circuit board 322 is accommodated within the accommodating space formed by the mid-frame support 40 and the back cover. That is, along the thickness direction (z-direction) of the electronic device, the circuit board 322 and the main control board can be located on the same side of the mid-frame support 40, such as... Figure 17 As shown, the electronic device may also include an electrical connection board 80, through which the circuit board 322 can be electrically connected to the main control board.

[0203] One end of the flexible connecting plate 321 can be electrically connected to the display panel 31. Part of the flexible connecting plate 321 can pass through the notch structure on the middle frame support member 40 (not shown in the figure). The other end of the flexible connecting plate 321 can extend to the side of the middle frame support member 40 facing away from the display panel 31, so that the other end of the flexible connecting plate 321 is electrically connected to the circuit board 322 located on the side of the middle frame support member facing away from the display panel 31, thereby realizing the electrical conduction between the display panel 31 and the main control board.

[0204] The circuit board 32 of the display screen 30 is divided into two parts: a flexible connecting plate 321 and a circuit board 322. The flexible connecting plate 321 enables electrical connection between the display panel 31 and the circuit board 322 and the main control board. The flexible connecting plate 321 passes through the notch structure. As a structural component for realizing electrical connection, the flexible connecting plate 321 can have a relatively small size. This helps to reduce the size of the notch structure, ensures the high strength of the middle frame support 40, improves the reliability of the screen assembly and electronic equipment, and allows the middle frame support 40 to provide a larger assembly aperture, facilitating the assembly of various structural components of the electronic equipment.

[0205] For example, by designing the shape, quantity, and size of the flexible connecting plate 321, the size of the flexible connecting plate 321 and the notch structure can be reduced while meeting the electrical connection function requirements. For instance, the number of flexible connecting plates 321 can be multiple, with multiple spaced notch structures 423 provided on the middle frame support member 40 (see reference). Figure 16 As shown, the size of each notch structure 423 will be relatively small, and there is a partial middle frame support 40 between adjacent notch structures 423, which improves the strength of the middle frame support 40.

[0206] Figure 18 for Figure 14 A schematic diagram of the assembly process of electronic equipment.

[0207] For example, in actual assembly, see Figure 18As shown, the light source 35 and functional film layer 34 of the display screen 30 can be assembled, and then the display panel 31, flexible connecting plate 321, cover plate 33, and functional film layer 34 can be assembled to form a structural component. This structural component is placed in the receiving groove of the integrated structural component formed by the middle frame support 40 and the frame 10. The flexible connecting plate 321 is passed through the notch structure by means of folding or other methods, so that the other end of the flexible connecting plate 321 is placed on the side of the middle frame support 40 away from the display panel 31. The display screen 30 is at least partially fixed and attached to the receiving groove by means of adhesive or other methods, so that the bottom surface of the receiving groove of the display screen 30 and the middle frame support 40 are attached. The other end of the flexible connecting plate 321 is electrically connected to the circuit board 322, and the circuit board 322 is electrically connected to the main control board. Then, the other structural components of the electronic device are assembled, and the back cover is assembled to complete the assembly of the electronic device.

[0208] Figure 19 This is a schematic diagram of a partially disassembled electronic device provided in an embodiment of this application.

[0209] Or, in some examples, see Figure 19 As shown, the notch structure 423 on the mid-frame support 40 can have a relatively large size, allowing the other end of the circuit board 32 to pass through. That is, one end of the circuit board 32 is electrically connected to the display panel 31, and the other end of the circuit board 32 can pass through the notch structure 423 of the mid-frame support 40 and wrap around to the side of the mid-frame support 40 away from the display panel 31. The portion of the circuit board 32 located between one end and the other end is accommodated within the notch structure 423. This reduces the structural design difficulty and requirements for the circuit board 32. When the mid-frame support 40 and the frame 10 are two independent structural components, the circuit board 32 can pass through the notch structure 423 first, and then the frame 10 can be assembled; alternatively, the frame 10 can be assembled first, and then the circuit board 32 can pass through the notch structure 423, reducing the requirements for assembly sequence and precision, and improving assembly efficiency.

[0210] For example, the number of notch structures 423 can be one, ensuring that the other end of the circuit board 32 can wrap around to the side of the middle frame support 40 away from the display panel 31, and ensuring that the middle frame support 40 has good strength and a large assembly layout space. The shape and structure of the notch structure 423, the relative positional relationship between the notch structure 423 and the main control board, etc. can be the same as in the example above where the middle frame support 40 and the frame 10 are two independent structural components, and will not be repeated here.

[0211] Figure 20 for Figure 19 A schematic diagram of the split structure of the screen components in the image. Figure 21 for Figure 20 A structural diagram showing the assembly of the middle frame support, side frame, and assembly plate.

[0212] To ensure the strength of the middle frame support 40 and the assembly space, see [reference needed]. Figure 20 As shown, the mid-frame support 40 may further include an assembly plate 43, which may be disposed within the notch structure 423 of the mid-frame support 40. The assembly plate 43 may partially cover the notch structure 423 to ensure that the notch structure 423 has space to accommodate the circuit board 32. (As shown in the diagram...) Figure 21 As shown, the assembly plate 43 is assembled within the notch structure 423, and part of the notch structure 423 is not covered, so that part of the circuit board 32 can be accommodated within this part of the notch structure 423.

[0213] Under the condition that part of the circuit board 32 is accommodated in the notch structure so that the other end of the circuit board 32 can be wrapped around to the side of the middle frame support 40 away from the display panel to achieve electrical connection with the main control board, etc., an assembly plate 43 is provided on the notch structure 423. The assembly plate 43 can improve the strength of the middle frame support 40 and increase the assembly layout space of the middle frame support 40, which facilitates the assembly of various structural components of the electronic device.

[0214] See also Figure 20 As shown, when assembling the mid-frame support 40 and the display screen 30, the display screen 30 is placed in the receiving groove 40a of the mid-frame support 40, so that the other end of the circuit board 32 passes through the notch structure 423, and a portion of the circuit board 32 is accommodated within the notch structure 423. Then, the mounting plate 43 is fixed within the notch structure 423, covering a portion of the notch structure 423, with a portion of the circuit board 32 located within the portion of the notch structure 423 not covered by the mounting plate 43.

[0215] It should be noted that in the example where the notch structure 423 is relatively large and is equipped with the assembly plate 43, the mid-frame support 40 and the frame 10 can be an integral structural component, or the mid-frame support 40 and the frame 10 can be two independent structural components. The screen assembly 102 may include the frame 10, or the screen assembly 102 may not include the frame 10.

[0216] like Figure 20 As shown, taking the mid-frame support 40 and the frame 10 as an integral structural component, with a relatively large notch structure 423 on the mid-frame support 40 as an example, the display screen 30 can be mounted on one side of the mid-frame support 40, and the back cover (not shown in the figure) can be mounted on the side of the mid-frame support 40 away from the display screen 30, for example along the thickness direction (z direction) of the electronic device 100, with the back cover and the display screen 30 respectively located on opposite sides of the mid-frame support 40.

[0217] The back cover and the mid-frame support 40 form an accommodating space (not shown in the figure), within which various structural components of the electronic device 100 can be housed. For example, the main control board 60 and the battery (not shown in the figure) of the electronic device 100 can be housed within the accommodating space.

[0218] A receiving groove 40a can be formed on one side of the mid-frame support member 40, and notch structures 423 can be distributed on the bottom surface of the receiving groove 40a. The display screen 30 is disposed in the receiving groove 40a, and the side of the display screen 30 facing the mid-frame support member 40 can be attached to the bottom surface of the receiving groove 40a. The shape and structure of the receiving groove 40a, as well as the assembly position and assembly method between the receiving groove 40a and the display screen 30, can be referred to the above, and will not be repeated here.

[0219] The structure of the middle frame support 40 can be the same as in the example above where the middle frame support 40 and the frame 10 are two independent structural components. For example, the middle frame support 40 may include a side frame and a middle plate, with the side frame surrounding the middle plate. The side frame may include a first frame portion and a second frame portion, with the first frame portion protruding from the first surface of the middle plate, and the first frame portion and the middle plate forming a receiving groove. The second frame portion may protrude from the second surface of the middle plate. Alternatively, the middle frame support 40 may not include a side frame or a second frame portion; specific implementation methods can be found above and will not be repeated here.

[0220] The back cover and display screen 30 can be assembled with the mid-frame support 40 respectively. The assembly position and method of the back cover, display screen 30 and mid-frame support 40 can be the same as in the example above where the mid-frame support 40 and the frame 10 are two independent structural components. For example, the display screen 30 is attached to the first surface of the mid-plate. The back cover can be assembled on the end face of the second frame part away from the mid-plate, and the second frame part, the mid-plate and the back cover form an accommodating space. The specific implementation method can be referred to above, and will not be repeated here.

[0221] The display screen 30 can be completely accommodated within the receiving groove 40a of the mid-frame support 40. Alternatively, the display screen 30 can be partially located outside the receiving groove 40a. For example, the cover plate of the display screen 30 can be fitted onto the end face of the first frame portion away from the mid-frame. After the display screen 30 is assembled with the mid-frame support 40 and the frame 10, the side of the cover plate away from the receiving space and one end face of the frame can be flush. Specific implementation methods can be found above and will not be repeated here.

[0222] The mid-frame support 40 may also include a reinforcing member, which, together with the sidewall of the mounting slot on the mid-plate, can form a receiving compartment for accommodating the battery. The structure, molding material, thickness, mounting position and method of the reinforcing member with the mid-plate can be referred to the above, and will not be repeated here.

[0223] The molding material of the middle frame support 40 and the molding material of the frame 10 can be the same, or in some examples, the molding materials of the two can be different. The specific materials and thicknesses can be the same as in the example above where the middle frame support 40 and the frame 10 are two independent structural parts, as can be found above.

[0224] Figure 22 for Figure 19 A schematic diagram of the assembly process of electronic equipment.

[0225] For example, taking the middle frame support 40 and the side frame 10 as an integral structural component, with a relatively large notch structure 423 opened on the middle frame support 40, see [reference]. Figure 22 As shown, during actual assembly, the light source 35 can be assembled onto the assembly plate 43, allowing the display panel 31, circuit board 32, cover plate 33, and functional film layer 34 to be assembled into a single structural component. This component is placed within the receiving groove of the integrated structural component formed by the mid-frame support 40 and the frame 10. The circuit board 32 is then passed through the notch structure by folding or other means, with its other end positioned on the side of the mid-frame support 40 away from the display screen 30. The assembly plate 43 is then assembled onto the notch structure of the mid-frame support 40. The display screen 30 is at least partially fixed into the receiving groove using methods such as adhesive, ensuring the bottom surfaces of the groove between the display screen 30 and the mid-frame support 40 are in contact. The other end of the circuit board 32 is then electrically connected to the main control board. Finally, the other structural components of the electronic device are assembled, and the back cover is assembled, completing the assembly of the electronic device.
