An electronic device

Abstract

This application discloses an electronic device in which the cavity wall surrounding the second cavity protrudes towards the recessed area of ​​the battery. This creates a recess on the side away from the second cavity, providing space for the installation of the side button FPC. This allows the buttons located on the side wall of the middle frame to be as far away from the top of the electronic device as possible, improving user operation flexibility. Furthermore, the first button is located on one side of the first cavity, so it does not occupy the space in the second cavity where the battery is placed. The volume of the battery installed inside the second cavity can be maximized to meet the design requirement of maximizing battery capacity. Moreover, the lower position of the first button also facilitates the setting of an antenna slot in the middle frame section between the first button and the second button, improving the flexibility of antenna design.

Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to an electronic device. Background Technology

[0002] Currently, electronic devices include buttons and side button FPCs. Buttons are located on the side wall of the electronic device, while side button FPCs are located inside the electronic device. The side button FPC is electrically connected to the motherboard inside the electronic device, and some parts are equipped with contact terminals. When the user presses the button, the button touches the contact terminal on the side button FPC to trigger the corresponding function of the electronic device.

[0003] As users' demands for electronic device performance increase, the number of internal components and battery capacities in electronic devices are also increasing, limiting the space available for side button FPCs. The placement of side button FPCs within electronic devices directly affects the button's location on the side wall. The button's installation location directly impacts user convenience, battery capacity, and the layout of internal antennas, thus affecting the overall performance and quality of the electronic device. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that is easy to operate with buttons.

[0005] This application provides an electronic device, including:

[0006] The middle frame has a first cavity and a second cavity separated from each other on one side.

[0007] The motherboard and battery are located inside the first cavity and the battery is located inside the second cavity.

[0008] The first button and the side button FPC include a first part and a first contact part. The side wall surrounding the first cavity is provided with a first button and a first mounting surface. The first part is mounted on the first mounting surface, and the first contact part is provided on the first part. The first contact part is used to sense the action of the first button.

[0009] The cavity wall forming the second cavity includes a protrusion that protrudes toward the battery side so as to form a recess on the first mounting surface side, and a portion of the first part is located in the recess.

[0010] In this embodiment, the characteristics of the battery's own structure are fully utilized. Due to structural or electrical connection requirements, the battery has a recessed area on the side facing the first cavity. The cavity wall surrounding the second cavity protrudes towards the recessed area, thus forming a recess on the side away from the second cavity. This provides space for the first part of the side button FPC with the first contact portion to be installed, so that a part of the first part is located in the recess. This allows the first button to be as far away from the top of the electronic device as possible, optimizing the position of all buttons on the side wall of the middle frame. The installation position of all buttons can be moved down as a whole, improving the user's operational flexibility. Furthermore, the first button is set on one side of the first cavity, without occupying the space in the second cavity where the battery is placed, meeting the design requirement of maximizing battery capacity. Moreover, the lowering of the first button's position also facilitates the setting of an antenna slot in the middle frame section between the first and second buttons, improving the flexibility of antenna design and thus improving the overall performance of the device.

[0011] In one example, the battery includes a cell and a structural component. The cell has a first side facing a first cavity. The structural component is located outside the cell, and the structural component forms a recessed region on one side of the first side. The opening of the recessed region faces away from the cell, i.e., the opening of the recessed region faces a protrusion, and a portion of the protrusion is located within the recessed region. This embodiment cleverly utilizes the gap in the structural component on one side of the first side, or an area of ​​the first side of the cell not covered by the structural component, so that the cavity wall of the second cavity faces the recessed region.

[0012] In one example, the structural component includes a protective layer located on the outer wall of the battery cell. Typically, the protective layer wraps around a portion of the outer wall of the battery cell. A first corner is located on the same side of the electronic device as the first button. The protective layer forms a protruding structure at the first corner. A recessed area and the protruding structure are arranged along the pressing direction of the first button, with the recessed area located on the side of the protruding structure opposite to the first button. This allows the recessed area to be as close as possible to the edge of the mid-frame, and the side button FPC to be as close to the edge as possible, minimizing the impact on the motherboard. The protruding structure can be approximately triangular in shape, with one apex pointing towards the first cavity. The triangular protruding structure occupies a small size in the pressing direction of the first button, which helps to position the first button as close as possible to the edge of the mid-frame. Of course, the protruding structure can also be other shapes, such as rectangles or other structures.

[0013] One example also includes:

[0014] The first partition is used to separate the first cavity and the second cavity;

[0015] The structural components also include an electrical connection assembly, which includes a battery FPC for electrical connection between the battery cell and the motherboard. The battery FPC includes a first section located between a first side surface and a first separator, and a recessed area located between the protruding structure at the first corner and the battery FPC. The electrical connection assembly can be located in the middle of the first side surface of the battery cell, or at the end of the first side surface away from the first corner. This allows for a larger space in the recessed area, facilitating the placement of the protrusion and providing more space for the installation of the side button FPC.

[0016] In one example, the electrical connection assembly further includes a protective element located in the second cavity. A portion of the protective element is connected to the outer wall of the battery cell. The protective element forms a protective cavity on the side of the first side facing the first separator, and the first segment is located within the protective cavity. The protective element can position and protect the first segment of the side-key FPC, preventing the side-key FPC from moving and wearing during use, and improving the service life of the side-key FPC.

[0017] In one example, the protective component includes a first plate, a second plate, and a third plate. The third plate is located between a first separator and a first side surface. The first and second plates are respectively connected to the two sides of the third plate extending along the length of the first separator. The first plate is connected to the side of the battery cell facing the opening of the second cavity, and the second plate is located on the side of the battery cell facing away from the first plate. A protective cavity is formed between the first, second, and third plates and the first side surface. In this example, the protective component has a roughly rectangular structure that matches the shape of the battery cell, facilitating its secure connection with the battery cell. Furthermore, the protective component occupies a relatively small space.

[0018] In one example, at least one limiting plate is provided on the side of the third plate opposite to the battery cell. When there are two or more limiting plates, they can be arranged at intervals along the pressing direction of the first button. The limiting plates are located in the second cavity, and a positioning groove is formed between the limiting plates and the third plate. The battery FPC includes a second section located between the third plate and the first separator. The second section is connected to the first section and passes through the positioning groove. The end of the second section away from the first section extends into the first cavity to electrically connect to the main board. This ensures reliable positioning of the battery FPC, reduces the probability of the battery FPC moving relative to the protection board during use, avoids wear on the battery FPC, and improves the overall reliability of the device.

[0019] In one example, the protrusion connects between the first partition and the side wall of the middle frame, and the protrusion is connected to the side wall of the first partition facing the second cavity. This connection between the protrusion and the side wall of the middle frame, and to the side wall of the first partition facing the second cavity, provides a larger installation space for the side key. The thickness of the protrusion is less than the thickness of the first partition, minimizing the space occupied by the protrusion.

[0020] In one example, the first side also has a second corner, which is arranged along the pressing direction of the first button, and the protective layer also forms a protruding structure at the second corner. In this embodiment, the protruding structures of the first and second corners can provide a certain degree of protection for the battery cell, while also improving the overall installation stability of the battery.

[0021] In one example, the protective layer is an aluminum-plastic protective film. This film provides good protection for the battery cell and is lightweight, which helps reduce the overall weight of the device. The protective layer can be applied circumferentially to the battery cell, covering a portion of its larger surfaces. The larger surfaces of the battery cell refer to the two largest surfaces of the cell, which are connected by a circumferential surface. One of these larger surfaces is attached to the middle plate of the mid-frame.

[0022] In one example, a second button is also included. The second button is disposed on the side wall of the middle frame that forms the first cavity, and is located on the side of the first button away from the battery cell. The middle frame side button FPC also includes a third part and a second contact part. A second mounting surface is also provided on the middle frame, the third part is mounted on the second mounting surface, and the second contact part is disposed on the third part. The second contact part is used to sense the action of the second button. Having a relatively large number of buttons can improve the functional versatility of electronic devices.

[0023] In one example, the first mounting surface and the second mounting surface are spaced apart by a predetermined distance, with the first mounting surface located on the side of the second mounting surface opposite to the second button. The position of the first mounting surface is determined by the recessed area on the battery cell. Although the first mounting surface is closer to the motherboard on the x-axis, this solves the problem in the prior art where the first button occupies space in the second cavity in the y-direction.

[0024] In one example, the side button FPC also includes a second part located in the first cavity. This second part has a connection terminal for electrical connection to the motherboard; one end of the second part connects to the first part, and the other end connects to the third part. In this example, the two buttons are connected to the motherboard via a single side button FPC. The side button FPC uses less material, which helps reduce the overall weight of the device. Of course, the first and second parts can also be independent and unconnected, offering greater installation flexibility.

[0025] In one example, the mid-frame includes a metal frame with an antenna slot in the section between the first and second buttons. The antenna slot is filled with a plastic body to improve the flexibility of the antenna design. Attached Figure Description

[0043] This application has conducted in-depth research on current electronic devices with two buttons on the sidewall, and found that there are roughly two ways to arrange the buttons in current electronic devices: Please refer to... Figure 1 The first method involves placing the first button A on one side of the motherboard cavity 11' and the second button B on one side of the battery compartment 12'. This balances the convenience of operating both buttons. However, placing the second button B on the battery compartment side requires space due to the structure of the side button FPC 13', resulting in a relatively small battery compartment 2'. For the second method, please refer to [link / reference]. Figure 2 By placing both the first button A and the second button B on one side of the motherboard cavity 11', the battery compartment 12' becomes relatively large. However, the first button A is positioned too high, making it inconvenient for users to operate. Furthermore, for electronic devices that use the metal frame of the middle frame 1' as an antenna, the top antenna is positioned too close to the corner of the electronic device, which severely affects the antenna's performance and consequently the overall performance of the electronic device.

[0044] Therefore, balancing user ease of operation with maximizing overall machine performance is a challenge in this field.

[0045] Based on the above research, this application proposes an electronic device that improves the convenience of button operation without affecting battery capacity, and can also improve the efficiency of the electronic device's antenna to a certain extent.

[0046] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific examples.

[0047] The technical solutions provided in this application can be applied to various types of electronic devices, including handheld devices, in-vehicle devices, wearable devices, terminal devices, or other processing devices connected to a wireless modem. These devices may also include cellular phones, smartphones, personal digital assistant (PDA) computers, tablets, laptops, camcorders, video recorders, cameras, smartwatches, smart bracelets, augmented reality (AR) devices, virtual reality (VR) devices, in-vehicle computers, and other devices with imaging capabilities. This application does not impose any special limitations on the specific form of the aforementioned electronic devices. For ease of understanding, the following description uses a mobile phone as an example. A mobile phone can be a candybar phone or a flip phone.

[0048] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0049] like Figure 3 As shown, taking a mobile phone as an example, the electronic device 100 may include a mid-frame 1 and a back cover 7 (see [reference]). Figure 4 The diagram shows a structural understanding of the device, a camera module 3, and a screen 2. The mid-frame 1 and the back cover 7 are part of the housing of the electronic device 100; that is, the housing of the electronic device 100 may include the mid-frame 1 and the back cover 7. A sound outlet 101 is provided on the mid-frame 1 to facilitate the propagation of sound from the speaker to the outside of the electronic device 100. For example, an interface 102 may also be provided on the mid-frame 1 for electrical connection with external devices via a data cable, and a Subscriber Identity Model (SIM) card slot 103 may also be provided on the mid-frame 1 for installing a SIM card.

[0050] In this embodiment, the screen 2 and the back cover 7 are located on opposite sides of the middle frame 1. The middle frame 1 supports and fixes the screen 2, providing protection. The screen 2 is used to display image information or video. When the electronic device 100 is in use, the user can view the content displayed on the screen 2 or perform input operations on the electronic device 100.

[0051] Please refer to Figure 4 , Figure 4 for Figure 3 The BB cross-sectional view of the electronic device shown indicates that screen 2 includes a transparent cover plate 21 and a display screen 22. The transparent cover plate 21 and the display screen 22 are stacked and fixedly connected. The transparent cover plate 21 mainly serves to protect the display screen 22 and prevent dust. The material of the transparent cover plate 21 includes, but is not limited to, glass and acrylic. The display screen 22 can be a flexible display screen or a rigid display screen.

[0052] The mid-frame 1 may include a mid-plate 12 and a frame portion 11 connected to the periphery of the mid-plate 12. The mid-plate 12 and the frame portion 11 may be integrally formed or connected by welding, bonding, screws, or other methods. The screen 2 and the back cover 7 are located on opposite sides of the mid-plate 12. The material of the back cover 7 includes, but is not limited to, metal, plastic, fiberglass, glass, ceramic, etc. It is understood that in some other embodiments, when the mobile phone is a foldable screen phone, the screen 2 and the back cover 7 may also be the first screen and the second screen of the foldable phone, respectively. For example, the screen 2 is the inner screen of the foldable phone, and the back cover 7 is the outer screen of the foldable phone, or the screen 2 is the outer screen of the foldable phone, and the back cover 7 is the inner screen of the foldable phone. The frame portion 11 may include a metal frame and a plastic body 17, wherein the metal frame can be used as a frame antenna, for example, the metal frame may have a break (see reference). Figure 5 (Understanding), the break point, also known as the antenna slot, is filled with a plastic body 17. By properly setting the break point location, the antenna design requirements can be met.

[0053] The rear cover 7 and the middle plate 12 form a mounting cavity, inside which the motherboard 4 and the camera module 3 are installed (combined). Figure 3 The electronic device 100 includes electrical components such as a battery 9, a speaker, and a handset. The mainboard 4 can be mounted on the middle plate 12 of the middle frame 1. The mainboard 4 can be the core circuit board (a circuit board integrating major components such as a processor, system chip, and power chip) within the electronic device 100. The battery 9 can be electrically connected to the mainboard 4. For example, the battery 9 can be connected to the mainboard 4 via a flexible printed circuit board (FPC). The mainboard 4 has a processor that can control the battery 9 to supply power to the various electrical components in the electronic device 100, and control external circuitry to charge the battery 9.

[0054] The mounting cavity located on one side of the middle frame 1 can be divided into two or more chambers by a partition, for example, Figure 2The middle plate 12 of the middle frame 1 is provided with a first partition 13 and a second partition 14, and the mounting cavity is divided into a first cavity 1A, a second cavity 1B and a third cavity 1C. The first cavity 1A can be used to install components such as the motherboard 4, earpiece, and camera module. The second cavity 1B can be used to install the battery 9. The third cavity 1C can be used to install the sub-board. Figure 4 (Not shown in the image) (also known as a small board), the sub-board is also a circuit board. The main board 4 is located at the top of the electronic device 100, and the sub-board is located at the bottom of the electronic device 100. The following components can be installed on the sub-board: HOME button, LED light, speaker and contacts, etc.

[0055] Please refer to Figure 5 , Figure 5 for Figure 3 The diagram shows a schematic representation of the electronic device from direction A. The sidewalls of the middle frame 1 can be equipped with buttons for different functions; for example, Figure 5 The diagram shows two buttons on the side wall of the middle frame 1: a first button 5 and a second button 6, with the second button 5 closer to the top of the middle frame 1. Both buttons 5 and 6 are push-buttons, meaning pressing them triggers corresponding functions of the electronic device 100. A single button can trigger different functions under different usage conditions. For example, pressing the button at different positions, for different durations, or with different pressing frequencies can all trigger different functions. For instance, a long press of the first button 5 can trigger the power-on or power-off function, while a short press can trigger the screen display function. The second button 6 can be a volume button, used to increase or decrease the volume of the electronic device 100's speaker or earpiece. Simultaneous pressing of both buttons can also activate functions such as taking a photo.

[0056] Combination Figure 6 , Figure 7 and Figure 8 , Figure 6 for Figure 3 An exploded view of the structure of a portion of the electronic device shown. Figure 7 for Figure 6 A schematic diagram of the first button, second button, side button FPC8, and a portion of the middle frame in the structure shown; Figure 8 for Figure 3 The image shows a front view of the electronic device with the back cover removed. The shaded area indicates the approximate location of the contact surface between the back cover and the mid-frame. The shading is added solely to better distinguish the different parts of the mid-frame structure.

[0057] In this embodiment, the electronic device 100 further includes a side button FPC8, which has contact portions for sensing the action of the first button 5 and the second button 6. For example, the first button 5 includes a first conductive base 51 and two first latching portions 52. A first through hole 104 and two first slots 106 are provided on the side wall of the middle frame 1 forming the first cavity 1A. The first conductive base 51 passes through the first through hole 104 and can face the first contact portion 84 on the side button FPC8. The two first latching portions 52 respectively engage with the two first slots 106 to prevent the first button 5 from detaching from the side wall of the middle frame 1. The side wall forming the first cavity 1A has a first vertical wall 15. The side button FPC8 includes the first contact portion 84, and the first vertical wall 15 has a first mounting surface 121 facing the first button 5. The first contact portion 84 is mounted on the first mounting surface 121. The side button FPC8 has a connection end for connecting to the motherboard 4. Figures 6 to 8 The connection ends are not shown, but this does not prevent those skilled in the art from understanding and implementing the technical solution.

[0058] When the first button 5 is pressed, the first conductive base 51 contacts the first contact portion 84. The first contact portion 84 transmits the signal to the motherboard 4 through the circuit in the side button FPC8 to trigger the corresponding function. The first contact portion 84 can be a metal spring with good elasticity. Of course, the first contact portion 84 can also be other components.

[0059] The structure and installation structure of the second button 6 are basically the same as those of the first button 5. The difference is that the second button 6 has two conductive bases, which are defined as second conductive bases 61 in this paper. The second button 6 has two second snap-fit ​​parts 62. The second button 6 is snapped into the second slot 107 on the side wall of the middle frame 1 through the two second snap-fit ​​parts 62 to prevent the second button 6 from falling out of the middle frame 1. The middle frame 1 is also provided with a second vertical wall 16. The second vertical wall 16 has a second mounting surface 122 facing the second button 6. The side button FPC also has two second contact parts 85. The two second conductive bases 61 pass through the second through hole 105 on the side wall of the middle frame 1 and can be opposite to the two second contact parts 85 fixed on the second mounting surface 122. By pressing different positions of the second button 6, one of the two second conductive bases 61 can be selected to abut against its corresponding second contact part 85, or both second conductive bases 61 can be controlled to abut against their corresponding second contact parts 85 at the same time to trigger different functions. The second contact part 62 can also be a metal spring sheet, which has good elasticity and is highly responsive.

[0060] Please refer to Figure 9 , Figure 9This is a schematic diagram of the battery structure, with dashed lines indicating the outer contour of the battery cell. In this embodiment, the battery 9 includes a battery cell 91, a protective layer 921, and an electrical connection assembly 922. In this embodiment, the protective layer 921 and the electrical connection assembly 922 are located on the outside of the battery cell; in this embodiment, the protective layer 921 and the electrical connection assembly 922 are collectively referred to as structural component 92. The battery cell 91 in this embodiment includes a housing with an opening, tabs and electrode coils inside the housing, a cover plate at the opening of the housing, and electrode posts on the cover plate. Figure 9 The specific structure of the battery cell 91 is not shown, but this does not impede the understanding of those skilled in the art regarding the above description. The battery cell 91 can be rectangular in shape. A regular rectangular shape is beneficial for the layout of internal components of electronic devices and can achieve a larger battery capacity in a smaller volume. Of course, the battery cell 91 can also be other shapes, such as hexagonal or circular, etc.

[0061] Please combine Figure 8 Understanding, the electrical connection assembly 922 is located on the first side 912 of the battery cell 91. Figure 9 (Identified), the first side 912 is the side where the electrode post of the battery cell 91 is set. The first side 912 is adjacent to the first cavity 1A, that is, the first side 912 faces the first cavity 1A. The function of the electrical connection assembly 92 is to electrically connect the battery cell 91 to the main board 4. The battery 9 can supply power to the main board 4, and can supply power to other electrical components of the electronic device 100 through the main board 4.

[0062] In this embodiment, the length of the electrical connection component 922 on the x-axis is less than the length of the first side surface 912. That is to say, the electrical connection component 922 only occupies a part of the length space of the first side surface 912, and does not occupy the entire length space of the first side surface 912.

[0063] Please refer to Figure 9The first side surface 912 of the battery cell 91 has two corners, namely a first corner 901 and a second corner 902. The first corner 901 is located on the same side of the electronic device as the first button 84, and the second corner 902 is located on the side of the electronic device away from the first button 84 along the x-axis. The protective layer 921 forms a protruding structure 9211 in the first corner 901, which protrudes towards the first separator 13. The battery cell 91 also has a second corner 902. The first corner 901 and the second corner 902 are arranged along the pressing direction (x-axis) of the first button 5, and the protective layer 921 also forms a protruding structure 9211 in the second corner 902. There is a recessed area 9A between the protruding structure 9211 of the first corner 901 and the electrical connection assembly 922. In other words, the structural component located outside the battery cell 91 protrudes from the first side 912 of the battery cell 91, and a structure formed on one side of the first side 912 has a recessed area 9A. This allows a portion of the cavity wall surrounding the second cavity 1B to protrude towards the battery side, forming a recess on the first mounting surface 121, providing mounting space for the side button FPC8. Thus, the first contact portion can be mounted in the recess, and the first button 5 can be mounted as close as possible to the battery compartment side.

[0064] In this embodiment, the thickness of the protrusion 132 is less than the thickness of the first partition 13, minimizing the space occupied by the protrusion 132. The protrusion 132 connects between the first partition 13 and the side wall of the middle frame 1, and connects to the side wall surface of the first partition 13 facing the second cavity 1B, thus providing a larger installation space for the side key FPC8. The protrusion 132 can be approximately arc-shaped, and the recess 131 is also approximately arc-shaped.

[0065] Figure 10 The diagram illustrates the mounting height of the first side button 5 on the middle frame 1 in this application, and the mounting height of the first side button on the middle frame in two prior art methods. Figure A1 shows the mounting position of the first side button 5 on the middle frame in this application; Figure A2 shows the mounting position of the first contact portion of the first side button 5' on the side button FPC in the prior art, which is completely located within the motherboard cavity; and Figure A3 shows the mounting position of the first contact portion of the first side button 5'', which is completely located beside the battery compartment. Figure 10 As can be seen from the figure, the height of the first side button 5 in this application is lower than the height of the first side button 5' in Figure A2. Furthermore, in this embodiment, the recessed area of ​​the battery 9 itself is fully utilized to avoid the side button FPC, thus not affecting the battery capacity.

[0066] In this embodiment, because the battery cell 91 of the battery 9 is externally provided with a protective layer 921 and an electrical connection component 922, the battery 9 is not a square structure. In particular, on the side of the battery 9 where the electrical connection component 922 is located, the battery 9 has a recessed area 9A. This embodiment fully utilizes this structural feature of the battery 9, making the cavity wall surrounding the second cavity 1B protrude towards the recessed area 9A. This creates a recess on the side away from the second cavity 1B, providing space for the installation of the side button FPC, so that a portion of the side button FPC with the first contact portion is located in this recess. This allows the first button 5 to be as far away from the top of the electronic device as possible, optimizing the position of all buttons on the side wall of the middle frame. The installation position of all buttons can be moved down as a whole, improving the user's operational flexibility. Furthermore, the first button 5 is located on one side of the first cavity, without occupying the space in the second cavity where the battery is placed, i.e., without occupying the space in the second cavity 1B along the y-direction, meeting the design requirement of maximizing battery capacity. Moreover, the lowered position of the first button 5 also facilitates the setting of an antenna slot on the middle frame between the first button 5 and the second button 6, improving the flexibility of antenna design. As described above, the frame portion 11 of the middle frame 1 may include a metal frame with breaks to form antenna slots. The antenna slots may be filled with a plastic material 17. During injection molding, the metal frame and other metal materials constituting the middle frame 1 are structurally fixed to the plastic material, and the plastic material can fill the breaks in the metal frame.

[0067] Please refer to Figure 11 and Figure 12 understand, Figure 11 for Figure 8 The structural diagram shown is a simplified representation of the motherboard. Figure 12 middle Figure 11 A magnified view of the area at position P2. Figure 11 and Figure 12 The side-key FPCs are also marked with shaded areas to facilitate identification by those skilled in the art. Figure 11 and Figure 12 The components are clearly defined. In this embodiment, the first mounting surface 121 and the second mounting surface 122 have a predetermined distance L, and the first mounting surface 121 is located on the side of the second mounting surface 122 opposite to the second button 6. Figure 12 Viewed from the center, the first mounting surface 121 is located to the right of the second mounting surface 122. Compared with the second mounting surface 122, the first mounting surface 121 is closer to the motherboard 4. The position of the first mounting surface 121 is mainly determined by the position of the recessed area 9A on the battery 9. Although the first mounting surface 121 is closer to the motherboard 4 on the x-axis, it can solve the problem in the prior art where the first button 5 occupies the space of the second cavity 1B in the y-direction.

[0068] Accordingly, the corner of the motherboard 4 adjacent to the first button 5 has a clearance portion 42 (please refer to...). Figure 6This is to meet the installation requirements of the first button 5. The clearance part 42 is relatively small and will not affect the setting of the components on the motherboard 4.

[0069] In addition, a clearance structure 41 can also be set on the motherboard 4 to accommodate the camera module.

[0070] Please combine Figure 11 and Figure 12 In one example, the first button 5 and the second button 6 can be connected to the motherboard via a side button FPC8 with the following structure. Exemplarily, the side button FPC8 includes a first part 81, a second part 82, and a third part 83 connected together. The first part 81 is mounted on a first mounting surface 121, and a first contact part 84 is disposed on the first part 81. The second part 82 is located in a first cavity 1A and has a connection end for electrical connection with the motherboard 4. This connection end can be a connector, a solder pad, or a wire, etc. The third part 83 is mounted on a second mounting surface 122, and a second contact part 85 is disposed on the third part 83. In this example, the two buttons are connected to the motherboard 4 via a single side button FPC8. The side button FPC uses less material, which helps reduce the overall weight of the device.

[0071] Of course, each button can also be connected to the motherboard 4 via a separate side button FPC, which makes the side button FPC settings more flexible.

[0072] In this embodiment, the protective layer 921 can be an aluminum-plastic protective film, wrapped around the periphery of the battery cell 91. The battery cell 91 provided in this application has a protective layer 921 on all four sides. The protective layer 921 can provide good protection for the circumference of the battery cell 91.

[0073] Please see again Figure 11 The electrical connection assembly 922 includes a protective member 9221 and a battery FPC 9222. The protective member 9221 is located in the second cavity 1B and is partially connected to the battery 9. The protective member 9221 forms a protective cavity on the side of the first side 912 facing the first separator 13, and a portion of the battery FPC 9222 is located within the protective cavity. The two terminals of the battery cell 91 are also located within the protective cavity, and one end of the battery FPC 9222 is electrically connected to the two terminals of the battery cell 91. For the sake of simplicity in describing the technical solution, this application defines the portion of the battery FPC 9222 located within the protective cavity as the first segment 9222A. In this application, the protective cavity formed by the protective member 9221 can position and protect the battery FPC 9222.

[0074] Please combine Figure 13In one example, the protective element 9221 can be approximately U-shaped. The protective element 9221 includes a first plate 92211, a second plate 92212, and a third plate 92213. The third plate 92213 is located between the first partition 13 and the first side 912. The first plate 92211 and the second plate 92212 are respectively connected to the two sides of the third plate 92213 extending along the length direction of the first partition 13. The first plate 92211 is partially connected to the side of the battery cell 91 facing the opening of the second cavity 1B. The second plate 92212 is partially connected to the side of the battery cell 91 away from the first plate 92211. A protective cavity is formed between the first plate 92211, the second plate 92212, the third plate 92213, and the first side 912. In other words, the first plate 92211 and the second plate 92212 are bent from the third body toward the battery cell 91, and the battery cell 91 is partially inserted between the first plate 92211 and the second plate 92212. The first plate 92211 and the second plate 92212 are respectively connected to the large surface of the battery cell 91. The first plate 92211 and the battery cell 91, and the second plate 92212 and the battery cell 91 can be connected and fixed by adhesive bonding.

[0075] In this embodiment, the first plate 92211 and the second plate 92212 of the protective component 9221 are roughly parallel, the third plate 92213 is roughly vertical, the protective cavity is roughly rectangular, it occupies a relatively small space, and the protective component 9221 has a simple processing technology and low manufacturing cost.

[0076] In this embodiment, the first plate 92211 and the second plate 92212 may also have notches 922A at their opening positions to avoid corresponding structural or text markings on the battery cell 91. The position and shape of the notches 922A can be reasonably set according to the specific battery cell 91.

[0077] In this embodiment, the battery FPC9222 can extend a protective cavity from between the third plate and the first side 912. In order to improve the fixing reliability of the battery FPC9222, the section of the battery FPC9222 located outside the protective cavity can also be fixed in the following way.

[0078] Please see again Figure 13In one example, a limiting plate 9223 is also provided on the side of the third plate 92213 opposite to the battery cell 91. The limiting plate 9223 is located in the second cavity 1B, and a positioning groove is formed between the limiting plate 9223 and the third plate 92213. The battery FPC 9222 includes a second segment 9222B located between the third plate 92213 and the first separator 13. The second segment 9222B is connected to the first segment 9222A and passes through the positioning groove. In this way, the battery FPC 9222 is reliably positioned, reducing the probability of the battery FPC 9222 moving relative to the protection plate during use, avoiding wear of the battery FPC 9222, and improving the overall reliability of the device.

[0079] Please see Figure 13 In this embodiment, the battery FPC 9222 further includes a third segment 9222C, which is connected to the end of the second segment 9222B away from the first segment 9222A. An electrical connector 92221 is provided at the end of the third segment 9222C away from the second segment 9222B for electrical connection with the motherboard 4. The electrical connector 92221 can be a board-to-board connector; of course, the connection between the battery FPC 9222 and the motherboard 4 can also be achieved using solder pads or wires.

[0080] from Figure 13 In the middle section, the battery FPC9222 has two protruding second sections 9222B extending from both ends A1 and A2 of the third board 92213. Each second section 9222B is connected to a third section 9222C. An electrical connector 92221 is provided at the end of the third section 9222C away from the second section 9222B. In this way, the main board can be electrically connected to the battery cell 91 through each electrical connector 92221, improving the charging and discharging control of the battery cell 91.

[0081] Please refer to Figure 14 In this embodiment of the application, a first clearance opening 133 may be provided on the first partition 13 to allow the battery FPC9222 to extend from the second cavity 1B into the interior of the first cavity. The first clearance opening 133 may be a groove structure for easy processing.

[0082] Similarly, a second clearance opening 151 can be provided on the first vertical wall 15, through which the side wall FPCs on both sides of the first vertical wall 15 are connected. The second clearance opening 151 can also provide support for the side wall FPCs 8. Likewise, a third clearance opening 161 can be provided on the second vertical wall 16 to allow the side wall FPCs 8 to pass through.

[0083] In addition, a support block 1D is provided inside the first cavity. The support block 1D has mounting holes 1E for fixing the motherboard 4. The support block 1D is fixed to the middle plate 12.
