Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of these is the emergence of foldable mobile phones, computers and other electronic devices. The flexible screens of foldable electronic devices can flexibly change modes according to different usage scenarios. At the same time, they also have a high screen-to-body ratio and clarity. For example, when the phone is folded, it can be only the size of a traditional phone, which is convenient to carry, and when unfolded, it can have the display size of a tablet. These features make foldable devices one of the products that people are most sought after.

[0003] Currently, foldable electronic devices typically include a first structural member and a second structural member, which are rotatably connected via a rotating assembly. A battery cover is provided on one side of each of the first and second structural members, and two relatively rotatable door panels are provided on one side of the rotating assembly. The door panels and the battery cover are located on the same side of the electronic device, and the door panels typically extend below the battery cover. Circuit boards are also provided within the first and second housings, respectively. To ensure that the rotation between the first and second structural members is not affected, the circuit boards within the first and second housings are often electrically connected via a flexible printed circuit (FPC). Specifically, the FPC typically extends from the first housing through the rotating assembly and into the second housing. To prevent the FPC from sliding during relative rotation between the first and second housings, which could result in wear, two clamping steel sheets are typically provided within the first and second housings to secure the FPC tightly to the first and second housings. Taking the compression of the FPC in the first shell as an example, one end of the first compression steel sheet is connected to the battery cover, the other end of the first compression steel sheet is fixed to the second compression steel sheet by glue, and the other end of the second compression steel sheet is pressed on the FPC, thereby pressing and fixing the FPC on the inner wall of the first shell.

[0004] The FPC is pressed and fixed by the two pressing steel sheets. However, due to assembly tolerances during installation, the installation accuracy is low, which makes it easy for a gap to appear between the battery cover and the door panel. The gap width is difficult to control, and uneven gaps are likely to occur, affecting the aesthetics and reliability of the electronic equipment. Summary of the Invention

[0005] The present application provides an electronic device that solves the problem in existing electronic devices that the flexible circuit board is compressed by two compression steel sheets, resulting in a gap between the battery cover and the door panel and uneven gaps, which affects the aesthetics and reliability of the electronic device.

[0006] The present application provides an electronic device, comprising: a flexible circuit board, a rotating assembly, and two structural members connected in rotation by the rotating assembly;

[0007] It also includes two battery covers and two door panels located on the same side, the two door panels are arranged on the rotating assembly, and the two door panels are rotatably connected by the rotating assembly, the two battery covers are respectively arranged on the two structural members, the two battery covers are respectively located on both sides of the two door panels, and the battery covers partially cover the adjacent door panels;

[0008] The invention also includes a pressing member disposed within the structural member. One end of the flexible circuit board is located within one of the two structural members, and the other end of the flexible circuit board passes through the rotating assembly and extends into the other structural member. The pressing member is pressed against the side of the flexible circuit board facing away from the structural member, and one end of the pressing member is connected to the battery cover, while the other end of the pressing member is connected to the structural member. In this way, the flexible circuit board is located between the pressing member and the structural member, and the two ends of the pressing member are respectively connected to the battery cover and the structural member, thereby pressing and fixing the flexible circuit board between the structural member and the pressing member, thereby achieving compression and fixation of the flexible circuit board and reducing the movement of the flexible circuit board.

[0009] The flexible circuit board is clamped by a clamping member, and the connection between the battery cover and the structural member is also achieved through the clamping member, saving at least one clamping steel sheet, thereby shortening the size chain of the clamping member between the structural member and the battery cover, and thus improving the assembly accuracy of the clamping member. The battery cover is connected to the structural member through the clamping member, which helps to improve the assembly accuracy of the battery cover and facilitates improving the accuracy of the installation position of the battery cover, thereby facilitating the control of the position of the battery cover and the gap between the battery cover and the door panel, reducing or avoiding the problem of uneven gaps, and helping to improve the aesthetics and reliability of the electronic device.

[0010] In one possible implementation, the structural member includes a frame and a connector, the frame is connected to the rotating assembly via the connector, a portion of the flexible circuit board is located on the connector, and a portion of the flexible circuit board is located on an end surface of the frame facing the connector;

[0011] The pressing member includes a connected pressing portion and an abutting portion, the pressing portion is located on a side of the flexible circuit board facing away from the connector, and the pressing member presses a portion of the flexible circuit board onto the connector through the pressing portion;

[0012] The abutting portion abuts against the side of the flexible circuit board facing away from the end surface, and the pressing member presses a portion of the flexible circuit board against the frame through the abutting portion. In other words, the pressing member presses and secures the flexible circuit board in two areas using the crimping portion and the abutting portion, respectively. This can enhance the fixing strength of the flexible circuit board, further reduce or prevent movement of the flexible circuit board, and contribute to improving the reliability of the electronic device.

[0013] In one possible implementation, the clamping member further includes a fixing portion, which is located above the side of the crimping portion facing the battery cover. The fixing portion is connected to the battery cover, and one end of the fixing portion is connected to the abutting portion, while the other end of the fixing portion extends toward the rotating assembly. That is, the fixing portion is located on the end of the abutting portion facing away from the crimping portion, and the fixing portion is a flange structure formed on this end and extending toward the rotating assembly. The battery cover is connected to the fixing portion, providing a large contact connection area, which helps to improve the connection strength between the clamping member and the battery cover.

[0014] In one possible implementation, the pressing member is further provided with a support portion, one end of which is connected to the crimping portion, and the other end of which extends below the door panel. The support portion abuts the door panel to support the door panel and abut the battery cover. The support portion supports the door panel, thereby abutting the door panel and the battery cover. This eliminates the gap between the door panel and the battery cover, helps reduce assembly tolerances and errors between the battery cover and the door panel, and effectively improves the assembly accuracy of the door panel, battery cover, and pressing member, further enhancing the aesthetics and reliability of the electronic device.

[0015] At the same time, the support part supports the door panel so that the door panel abuts against the battery cover, so that the door panel can provide support for the battery cover, reducing or avoiding the phenomenon of part of the battery cover hanging in the air, thereby reducing or avoiding the problem of pressing the battery cover area and causing a void, thereby improving the user experience.

[0016] In a possible implementation, at least a portion of the end surface is an inclined surface, and the flexible circuit board is located on the inclined surface;

[0017] The abutting portion is arranged at an angle relative to the pressing portion, and the inclination direction of the abutting portion is consistent with the inclination direction of the inclined surface. The side of the abutting portion facing away from the rotating assembly forms an abutting plane, and the abutting portion presses the flexible circuit board onto the inclined surface via the abutting plane. In this way, the abutting plane on the side of the abutting portion facing away from the rotating assembly can abut against the inclined surfaces of the flexible circuit board and the frame, that is, the abutting plane, the flexible circuit board, and the inclined surface are in surface contact, effectively increasing the contact area between the abutting portion, the flexible circuit board, and the frame, thereby improving the sealing performance of the structural component and contributing to the improvement of the waterproof performance of the electronic device.

[0018] In one possible implementation, the supporting portion includes a connected connecting section and a supporting section, one end of the connecting section is connected to the crimping portion, the other end of the connecting section extends to the bottom of the door panel, the supporting section is located on the side of the other end of the connecting section facing the door panel, and the side of the supporting section facing away from the connecting section abuts against the door panel.

[0019] In one possible implementation, a gap is provided between the support section and the connecting section. This can reduce the weight of the pressing member and contribute to the lightweight design of the electronic device. Specifically, the support section can be formed by bending the other end of the connecting section and extending toward the crimping portion.

[0020] In one possible implementation, the support portion further includes an extension segment, located on the side of the connecting segment facing the battery cover, with one end of the extension segment connected to the support segment and the other end of the extension segment extending toward and connected to the crimping portion. In this way, the support segment is connected to the crimping portion via the extension segment and the connecting segment, thereby increasing the support strength of the support portion for the door panel. Furthermore, the location of the extension segment on the connecting segment further strengthens the connection between the support segment and the crimping portion, further increasing the support strength of the support portion for the door panel.

[0021] In a possible implementation, a first fastener is further included, a first assembly hole is provided on the connecting section, a second assembly hole coaxial with the first assembly hole is provided on the extension section, one end of the first fastener abuts against the support portion, and the other end of the first fastener passes through the first assembly hole and the second assembly hole and is connected to the connector.

[0022] In a possible implementation, connecting portions are further provided on both sides of the crimping portion, and the crimping portion is connected to the connector through the connecting portions.

[0023] In a possible implementation, a second fastener is further included, a third assembly hole is opened on the connecting portion, one end of the second fastener abuts against the connecting portion, and the other end of the second fastener passes through the third assembly hole and is connected to the connector.

[0024] In one possible implementation, the connecting portion further comprises a first retaining hole, and the connecting body is provided with a first retaining member that cooperates with the first retaining hole. The cooperation between the first retaining hole and the first retaining member can pre-fix the compression member, facilitating operation of the second fastener to secure the compression member to the structural member, thereby facilitating assembly. Furthermore, the first retaining hole and the first retaining member can also serve as an alignment mechanism, facilitating rapid positioning of the compression member during assembly and improving assembly efficiency.

[0025] In one possible implementation, the abutment portion is provided with a second limiting hole, and the frame is provided with a second limiting member that cooperates with the second limiting hole. The cooperation between the second limiting hole and the second limiting member can also serve to pre-fix the pressing member and facilitate positioning of the pressing member during assembly, further improving assembly efficiency.

[0026] In one possible implementation, a seal is provided between the abutting plane and the flexible circuit board. The seal can protect the flexible circuit board to a certain extent, avoid direct friction between the flexible circuit board and the abutting plane, and reduce wear of the flexible circuit board by the rigid structure.

[0051] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0052] An electronic device provided in an embodiment of the present application may include, but is not limited to, a foldable fixed terminal or mobile terminal such as a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen TV, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, and a virtual reality device.

[0053] In the embodiments of the present application, the structure of the electronic device is described by taking a foldable mobile phone as an example, wherein the foldable mobile phone can be a foldable mobile phone with an inward folding screen, or the foldable mobile phone can be a foldable mobile phone with an outward folding screen.

[0054] Figure 1 This is a schematic diagram of the structure of an electronic device in a folded state provided by an embodiment of the present application. Figure 2 This is a schematic diagram of the structure of an electronic device in a semi-folded state provided by an embodiment of the present application. Figure 3 This is a schematic diagram of the front structure of an electronic device in a flattened state provided in an embodiment of the present application.

[0055] See also Figure 1 As shown, an electronic device 10 provided in an embodiment of the present application includes two structural members, such as a first structural member 11 and a second structural member 12, wherein the two structural members are connected by a rotating assembly 13 (refer to Figure 3 As shown in FIG, the first structural member 11 and the second structural member 12 are connected in rotation so that the two structural members can rotate relative to each other. For example, the first structural member 11 and the second structural member 12 can rotate toward each other, or the first structural member 11 and the second structural member 12 can rotate away from each other.

[0056] See also Figure 1 As shown in FIG, when the first structural member 11 and the second structural member 12 are rotated toward each other to overlap each other, the electronic device 10 is in a folded state. Figure 2 As shown, the first structural member 11 and the second structural member 12 can rotate in opposite directions and be relatively unfolded. Figure 3 As shown, when the first structure 11 and the second structure 12 move away from each other until the first structure 11 and the second structure 12 can no longer rotate (eg, the first structure 11 and the second structure 12 are in the same plane), the electronic device 10 is in a flattened state.

[0057] It should be noted that the electronic device 10 may include two structural members, that is, the number of the first structural member 11 and the second structural member 12 may both be one, so that the foldable screen mobile phone can be folded into two layers, for example, Figure 1 As shown, the foldable screen mobile phone may include a first structural member 11, a second structural member 12 and a rotating assembly 13. The first structural member 11 and the second structural member 12 are rotated to overlap each other, so that the electronic device 10 is in a two-layer form.

[0058] Alternatively, the electronic device 10 may also include multiple structural members, that is, the number of first structural members 11 and second structural members 12 may be multiple, and adjacent first structural members 11 and second structural members 12 are connected by a rotating assembly 13, so that the electronic device 10 can be folded into multiple layers. For example, the electronic device 10 may include two second structural members, one first structural member, and two rotating assemblies. The two second structural members are located on both sides of the first structural member and are rotatably connected to the first structural member via the rotating assemblies. One of the second structural members can be rotated with the first structural member to overlap, and the other second structural member can also be rotated relative to the first structural member to overlap, so that the electronic device 10 presents a three-layer folded shape. When two of the first structural member and the second structural member are rotated to the same plane, the electronic device 10 is flattened.

[0059] See also Figure 3 As shown, the electronic device 10 may further include a foldable flexible display screen 120, wherein the flexible display screen 120 may be disposed on the same side surface of the first structural member 11, the rotating assembly 13, and the second structural member 12. When the first structural member 11 and the second structural member 12 are folded, the flexible display screen 120 bends and adheres to the first structural member 11 and the second structural member 12. When the first structural member 11 and the second structural member 12 are unfolded, the flexible display screen 120 also unfolds.

[0060] For a foldable phone with an inward folding screen, the flexible display screen 120 is arranged on the inner surface of the first structural member 11, the rotating assembly 13 and the second structural member 12. For a foldable phone with an outward folding screen, see Figure 3 As shown, the flexible display screen 120 is arranged on the outer surfaces of the first structural member 11 , the rotating assembly 13 and the second structural member 12 .

[0061] It should be noted that when the electronic device 10 is in the folded state, the adjacent and opposing surfaces of the first structural member 11 and the second structural member 12 are referred to as inner surfaces, and the surface of the rotational assembly 13 on the same side as the inner surfaces of the first and second structural members 11 and 12 is referred to as the inner surface of the rotational assembly 13. The opposing surfaces of the first and second structural members 11 and 12 are referred to as outer surfaces, and the surface of the rotational assembly 13 on the same side as the outer surfaces of the first and second structural members 11 and 12 is referred to as the outer surface of the rotational assembly 13.

[0062] In some embodiments, the electronic device 10 may also be a laptop computer, which may include a first structural member 11 and a second structural member 12. The first structural member 11 and the second structural member 12 can rotate toward each other to overlap each other, placing the laptop computer in a folded state. Conversely, when the first structural member 11 and the second structural member 12 rotate away from each other from the overlapping state until they cannot rotate, the laptop computer is in a flat state. In the flat state, the portion of the flexible display screen 120 on the first structural member 11 can be used to display images, etc., while the portion of the flexible display screen 120 on the second structural member 12 can be used as a virtual keyboard, etc.

[0063] Figure 4 This is a schematic diagram of the back structure of an electronic device provided in an embodiment of the present application. Figure 5 A schematic diagram of the disassembled structure of an electronic device provided in an embodiment of the present application.

[0064] See also Figure 4 As shown, the electronic device 10 may further include two battery covers and two door panels, wherein the two battery covers are respectively provided on two structural members, and the battery covers and the door panels are located on the same side of the electronic device 10, for example, Figure 4 The electronic device 10 is an electronic device with a foldable screen. The two battery covers are respectively a first battery cover 14 and a second battery cover 15. The two door panels are respectively a first door panel 16 and a second door panel 17. The two battery covers are respectively located on the side of the first structural member 11 and the second structural member 12 away from the flexible display screen 120, that is, on the inner surface of the first structural member 11 and the second structural member 12. The two door panels can be respectively arranged on the rotating component 13 and located on the inner surface of the rotating component 13.

[0065] Combine Figure 5 As shown, the first structural member 11 and the second structural member 12 are connected via a rotating assembly 13 , wherein the rotating assembly 13 may be a hinge assembly, or the rotating assembly 13 may also be other structural members capable of achieving rotation.

[0066] Taking the rotating assembly 13 as a hinge assembly as an example, the rotating assembly 13 may include a rotating shaft 131, and a first rotating member 132 and a second rotating member 133 located on either side of the rotating shaft 131. The first rotating member 132 and the second rotating member 133 are respectively rotatably mounted on the rotating shaft 131. The first structural member 11 may be connected to the first rotating member 132, and the second structural member 12 may be connected to the second rotating member 133.

[0067] Two door panels can also be provided on the rotating assembly 13, with the two door panels located between the two battery covers. For example, the two door panels are respectively a first door panel 16 and a second door panel 17. The battery cover provided on the first structural member 11 is the first battery cover 14, and the battery cover provided on the second structural member 12 is the second battery cover 15. The first door panel 16 can be located on the first rotating member 132, and the second door panel 17 can be located on the second rotating member 133. The first door panel 16 is provided adjacent to the first structural member 11, and the second door panel 17 is provided adjacent to the second structural member 12. The first door panel 16 and the second door panel 17 are located between the first battery cover 14 and the second battery cover 15.

[0068] Continue to combine Figure 4 and Figure 5 As shown, a third door panel 190 may also be included. The third door panel 190 is located on the same side as the first door panel 16 and the second door panel 17. The third door panel 190 may be located on the rotating shaft 131 to shield and protect the rotating shaft 131. The first door panel 16, the second door panel 17 and the third door panel 190 are located on the outer surface of the rotating component 13 and cover the rotating component 13.

[0069] It should be noted that the electronic device 10 may include only two battery covers, and the two battery covers are respectively provided on the two structural members.

[0070] Alternatively, in some examples, the electronic device 10 may include multiple battery covers. For example, when the electronic device 10 includes multiple structural members, each structural member may be provided with a battery cover. Specifically, for example, if the electronic device includes two second structural members, one first structural member, and two rotating assemblies, the electronic device, when in a folded state, forms a three-layer foldable state. The two second structural members may each be provided with two second battery covers, and the one first structural member may be provided with one first battery cover.

[0071] Accordingly, the electronic device 10 may include two door panels, which are arranged on a rotating assembly 13. Each door panel may be a whole panel, or each door panel may be formed by splicing a plurality of sub-door panels.

[0072] Alternatively, in some examples, the electronic device 10 may include multiple door panels. For example, the electronic device includes multiple structural members, and two adjacent structural members are rotatably connected through a rotating assembly. When there are multiple rotating assemblies, two door panels may be provided on each rotating assembly.

[0073] Figure 6 A schematic cross-sectional view of an electronic device according to an embodiment of the present application is provided. Figure 7 for Figure 6 A magnified schematic diagram of the local structure, Figure 8 for Figure 7 A magnified view of the local structure.

[0074] See also Figure 6 and Figure 7 As shown, the two battery covers are located on either side of the two door panels, and the battery covers partially overlap the adjacent door panels. That is, the first battery cover 14 partially overlaps the first door panel 16, and the second battery cover 15 partially overlaps the second door panel 17. In other words, a portion of the first door panel 16 extends below the side of the first battery cover 14 facing the flexible display 120, and the projections of the first battery cover 14 and the second door panel 17 on the flexible display 120 partially overlap. A portion of the second door panel 17 extends below the side of the second battery cover 15 facing the flexible display 120, and the projections of the second battery cover 15 and the second door panel 17 on the flexible display 120 partially overlap.

[0075] It should be noted that, in order to ensure the relative rotation between the first structural member 11 and the second structural member 12 , the area of the overlapping portion between the battery cover and the door panel is relatively small.

[0076] Combine Figure 6 and Figure 7 As shown, the electronic device 10 also includes a flexible circuit board 110. One end of the flexible circuit board 110 can be located in one of the two structural members, and the other end of the flexible circuit board 110 passes through the rotating assembly 13 and extends into the other structural member. For example, a first circuit board (not shown) can be provided in the first structural member 11, and a second circuit board (not shown) can be provided in the second structural member 12. One end of the flexible circuit board 110 is located in the first structural member 11 and is electrically connected to the first circuit board. The other end of the flexible circuit board 110 passes through the rotating assembly 13 and extends into the second structural member 12, electrically connected to the second circuit board, thereby connecting the first circuit board and the second circuit board in the first structural member 11 and the second structural member 12 through the flexible circuit board 110.

[0077] Because the flexible circuit board is fixed at both ends, it is highly mobile during the relative rotation of the first and second structural members, causing friction with the first and second structural members, as well as other components, potentially leading to wear and failure. Furthermore, the flexible circuit board can easily fall into other structural members, affecting their performance. Therefore, a clamping structure is typically provided near the first and second structural members in the area near the rotating assembly to compress the flexible circuit board and secure it, minimizing or preventing movement of the flexible circuit board during rotation.

[0078] In the related art, two pressing steel sheets are usually used to realize the clamping setting of the flexible circuit board. For example, the two pressing steel sheets are respectively a first pressing steel sheet and a second pressing steel sheet. The first pressing steel sheet is connected to the battery cover by glue dispensing. The first pressing steel sheet is connected to the second pressing steel sheet by glue dispensing. The second pressing steel sheet is pressed on the flexible circuit board, thereby realizing the clamping and fixing of the flexible circuit board. Among them, the end of the first pressing steel sheet facing away from the rotating assembly can abut against the structural member, which can improve the sealing of the structural member, reduce or avoid the problem of water and other liquids entering through the gap between the door panel and the battery cover and flowing into the structural member, causing damage to the circuit board and the like inside the structural member, and improve the waterproof performance of the electronic device.

[0079] However, two or more pressing steel sheets are used to press and fix the flexible circuit board, and there is a large assembly tolerance between the two pressing steel sheets during assembly, resulting in low installation accuracy of the pressing steel sheets. The pressing steel sheets are connected to the battery cover to support the battery cover, which will reduce the setting position accuracy of the battery cover, making it easy for a gap to appear between the battery cover and the door panel (overlapping part), and due to the existence of assembly tolerances and assembly errors, the width of the gap is difficult to control, resulting in uneven gaps, which greatly affects the aesthetics and reliability of the electronic equipment.

[0080] At the same time, due to the existence of the gap and the uneven gap, part of the battery cover will be in a suspended state. In this way, when pressing on the battery cover area, it is easy to press the empty position, which reduces the user experience.

[0081] In addition, since at least two compression steel sheets need to be set in a structural member, when the two compression steel sheets are assembled in the structural member, the installation positions of the compression steel sheets need to cooperate with each other and not affect each other. In other words, the assembly method of the two compression steel sheets has many constraints, which may result in a smaller contact area between the end of the first compression steel sheet (the compression steel sheet adjacent to and connected to the battery cover) facing away from the transmission assembly and the structural member. For example, the contact between the two is usually point contact. This will affect the sealing of the structural member and reduce the waterproof performance of the electronic device.

[0082] Based on this, in an embodiment of the present application, a clamping member is used to implement a clamping setting for the flexible circuit board, reduce assembly tolerances and errors, improve the installation accuracy of the clamping member, and make it easier to control the position of the battery cover and the gap between the battery cover and the door panel, thereby helping to reduce or eliminate the gap between the battery cover and the door panel, thereby improving the aesthetics and reliability of the electronic device.

[0083] In the embodiment of the present application, the electronic device 10 further includes a pressing member, which is arranged in the structural member. The pressing member can be a pressing steel sheet. The pressing member is pressed on the side of the flexible circuit board 110 away from the structural member. One end of the pressing member is connected to the battery cover, and the other end of the pressing member is connected to the structural member. Figure 7 and Figure 8 As shown in FIG, taking the first pressing member 18 disposed within the first structural member 11 as an example, the first pressing member 18 is pressed against a portion of the flexible circuit board 110 located on the first structural member 11. One end of the first pressing member 18 is connected to the first battery cover 14, and the other end of the first pressing member 18 is connected to the first structural member 11. In this way, the flexible circuit board 110 is located between the pressing member and the structural member (e.g., the first pressing member 18 and the first structural member 11), while the two ends of the pressing member are respectively connected to the battery cover and the structural member, thereby pressing and fixing the flexible circuit board 110 between the structural member and the pressing member, thereby achieving compression and fixation of the flexible circuit board 110 and reducing the movement of the flexible circuit board 110.

[0084] The flexible circuit board 110 is clamped by an integrated clamping member, and the connection between the battery cover and the structural member is also realized by the clamping member, saving at least one clamping steel sheet, thereby shortening the size chain of the clamping member between the structural member and the battery cover, reducing the assembly tolerance and error of the clamping member, and improving the assembly accuracy of the clamping member. The battery cover is connected to the structural member through the clamping member, which helps to improve the assembly accuracy of the battery cover and facilitates improving the accuracy of the installation position of the battery cover, thereby facilitating the control of the position of the battery cover and the gap between the battery cover and the door panel, reducing or avoiding the problem of uneven gaps, and helping to improve the aesthetics and reliability of the electronic device 10.

[0085] In addition, a single pressing member is used to press the flexible circuit board 110. This eliminates the need for at least one pressing steel sheet, thus helping to reduce costs.

[0086] Figure 9 This is an enlarged schematic diagram of a partial internal structure of an electronic device provided in an embodiment of the present application. Figure 10 for Figure 9 A magnified view of the local structure. Figure 11 A schematic diagram of the assembly of a compression member, a flexible circuit board, and a structural member provided in an embodiment of the present application.

[0087] Among them, combined Figure 7 and Figure 9 As shown, a pressing member may be provided in the first structural member 11 and the second structural member 12 , respectively. For example, a first pressing member 18 is provided in the first structural member 11 , and a second pressing member 19 is provided in the second structural member 12 .

[0088] Among them, see Figure 10 As shown, the first pressing member 18 is pressed on the portion of the flexible circuit board 110 located on the first structural member 11, and combined with Figure 8 As shown, one end of the first pressing member 18 is connected to the first battery cover 14 , and the other end of the first pressing member 18 is connected to the first structural member 11 .

[0089] Combine Figure 9 As shown, the second pressing member 19 is pressed on a portion of the flexible circuit board 110 located on the second structural member 12, and one end of the second pressing member 19 is connected to the second battery cover 15, and the other end of the second pressing member 19 is connected to the second structural member 12.

[0090] Of course, in some examples, a pressing member may be provided only in the first structural member 11 , or a pressing member may be provided only in the second structural member 12 .

[0091] In the embodiment of the present application, the structural member may include a frame and a connector, and the frame is connected to the rotating assembly 13 via the connector. Specifically, the frame may be the middle frame of the electronic device 10, and the connector may be connected to the rotating member of the rotating assembly 13. The vertical height of the frame may be higher than the vertical height of the connector, that is, the end face of the frame facing the connector (the end face of the frame facing the connector opposite to the connector) is at least partially not blocked by the connector, but is exposed to the outside. When the flexible circuit board 110 extends from one of the structural members through the rotating assembly 13 into the other structural member, a portion of the flexible circuit board 110 will be laid on the end face of the frame facing the connector, and a portion of the flexible circuit board 110 will be laid on the connector.

[0092] For example, see Figure 10 and Figure 11 As shown, taking the first structural member 11 as an example, the first structural member 11 includes a first frame 111 and a first connector 112. The first frame 111 is connected to the first connector 112, and the first connector 112 can be connected to the first rotating member 132. A portion of the flexible printed circuit board 110 is laid on the first frame 111, and another portion of the flexible printed circuit board 110 is laid on the first connector 112.

[0093] Correspondingly, the second structural member 12 may include a second frame and a second connector, the second frame is connected to the second connector, the second connector is connected to the second rotating member 133, a portion of the flexible circuit board 110 is laid on the end surface of the second frame facing one end of the second connector, and a portion of the flexible circuit board 110 is laid on the second connector.

[0094] Figure 12 This is a schematic structural diagram of a compression member provided in an embodiment of the present application. Figure 13 A schematic side view of the structure of a compression member provided in an embodiment of the present application.

[0095] In the examples of this application, see Figure 12 As shown, the pressing member includes a crimping portion 181 and an abutting portion 182. When the pressing member is set on the structural member, the crimping portion 181 is located on the side of the flexible circuit board 110 facing away from the connector, that is, the crimping portion 181 is located on the portion of the flexible circuit board 110 laid on the connector. When the two ends of the pressing member are fixedly connected to the battery cover and the structural member respectively, the pressing member presses part of the flexible circuit board 110 onto the connector through the crimping portion 181.

[0096] The abutting portion 182 abuts against the side of the flexible circuit board 110 that is away from the above-mentioned end face, that is, the abutting portion 182 abuts against the part of the flexible circuit board 110 on this end face. When the two ends of the pressing member are respectively fixed to the battery cover and the structural member, the pressing member presses part of the flexible circuit board 110 against the end face of the frame facing the connector through the abutting portion 182.

[0097] That is, the pressing member presses and fixes the flexible circuit board 110 at two locations through the pressing portion 181 and the abutting portion 182 , thereby improving the fixing strength of the flexible circuit board 110 and further reducing or preventing the movement of the flexible circuit board 110 .

[0098] For example, combined with Figure 8 and Figure 11 As shown, taking the first pressing member 18 as an example, the pressing portion 181 of the first pressing member 18 is located on the side of the flexible circuit board 110 facing away from the first connecting body 112. The first pressing member 18 is connected to the first connecting body 112, and the first pressing member 18 presses and fixes the flexible circuit board 110 to the first connecting body 112 via the pressing portion 181. The abutting portion 182 of the first pressing member 18 abuts against the end surface of the flexible circuit board 110 facing away from the first frame 111 and toward the first connecting body 112. The two ends of the first pressing member 18 are respectively connected to the first battery cover 14 and the first connecting body 112, and the first pressing member 18 presses and fixes the flexible circuit board 110 to the end surface via the abutting portion 182.

[0099] At least a portion of the end surface of the frame facing one end of the connector is an inclined surface, and the flexible circuit board 110 is laid on the inclined surface. Figure 12 As shown, the abutment portion 182 can be tilted relative to the pressing portion 181, and the tilting direction of the abutment portion 182 can be consistent with the tilting direction of the inclined surface. The abutment portion 182 forms an abutment plane on the side away from the rotating component 13, and the abutment portion 182 presses the flexible circuit board 110 onto the inclined surface of the frame through the abutment plane.

[0100] Because a single pressing member not only compresses the flexible circuit board 110 but also connects the battery cover to the structural member, the pressing member's installation accuracy is improved, resulting in fewer constraints when the pressing member is installed within the structural member. This allows the side of the pressing member's abutting portion 182 facing away from the rotating assembly 13 to better abut the structural member's frame. This allows the majority of the abutting surface of the abutting portion 182 facing away from the rotating assembly 13 to abut against the flexible circuit board 110 and the inclined surface of the frame. This means that the abutting surface, the flexible circuit board 110, and the inclined surface are in surface contact, effectively increasing the contact area between the abutting portion 182, the flexible circuit board 110, and the frame, thereby improving the sealing of the structural member and contributing to enhanced waterproofing of the electronic device 10.

[0101] For example, combined with Figure 8 and Figure 11 As shown, taking the first pressing member 18 as an example, the end surface of the first frame 111 facing one end of the connector is an inclined surface, and the abutting portion 182 forms an abutting plane on the side facing away from the rotating component 13. The abutting portion 182 abuts the flexible circuit board 110 against the inclined surface of the first frame 111 through the abutting plane, and the abutting plane, the flexible circuit board 110 and the inclined surface are in surface contact, which has good sealing performance.

[0102] A seal 150 may be provided between the contact surface and the flexible circuit board 110. The seal 150 may be foam or other structural member capable of providing a seal. The seal 150 can further enhance the seal between the contact portion 182 and the inclined surface, further improving the waterproof performance of the electronic device 10.

[0103] In addition, the sealing member 150 is mostly a structure with a certain degree of flexibility, such as foam, which can play a certain protective role on the flexible circuit board 110, so that there is a sealing member 150 between the flexible circuit board 110 and the abutting plane of the abutting portion 182, which can avoid direct friction between the flexible circuit board 110 and the abutting plane and reduce wear on the flexible circuit board 110.

[0104] It should be understood that in the electronic device 10, structural parts, pressing parts, etc. are mostly rigid structures, and a seal 150 can be provided between the flexible circuit board 110 and the structure in contact with it. For example, a seal 150 can be provided between the crimping portion 181 and the flexible circuit board 110, between the flexible circuit board 110 and the connector, and between the flexible circuit board 110 and the inclined surface of the frame to avoid direct contact between the rigid structure and the flexible circuit board 110 and reduce wear on the flexible circuit board 110.

[0105] Among them, see Figure 12 As shown, connecting parts 185 are provided on both sides of the crimping part 181, and the crimping part 181 is connected to the connecting body of the structural member through the connecting parts 185. Figure 11 As shown, the electronic device 10 may further include a second fastener 140, and a third assembly hole 1851 may be opened on the connecting portion 185. One end of the second fastener 140 is against the connecting portion 185, such that one end of the second fastener 140 cannot pass through the third assembly hole. The other end of the second fastener 140 passes through the third assembly hole 1851 and is connected to the connector, thereby connecting the crimping portion 181 to the connector, and further fixing the pressing member on the structural member.

[0106] The second fastener 140 may be a screw, a pin, etc., and the third assembly hole 1851 may be a plain hole, or the third assembly hole 1851 may also be a threaded hole.

[0107] Continue to see Figure 11 and Figure 12 As shown, a first limiting hole 1852 may be provided on the connecting portion 185, and a first limiting member 1121 (such as Figure 11 A first stopper 1121 is provided on the first connector 112. The cooperation between the first stopper hole 1852 and the first stopper 1121 can pre-fix the compression member, facilitating the operation of the second fastener 140 to secure the compression member to the structural member, thus facilitating assembly. Furthermore, the first stopper hole 1852 and the first stopper 1121 can also serve as an alignment mechanism, facilitating rapid positioning of the compression member during assembly and improving assembly efficiency.

[0108] A second limiting hole 1822 can be opened on the abutting portion 182 of the pressing member, and a second limiting member 1111 cooperating with the second limiting hole 1822 is opened on the frame. The cooperation between the second limiting hole 1822 and the second limiting member 1111 can also play a role in pre-fixing the pressing member, and can also facilitate the positioning of the pressing member during assembly, thereby further improving the assembly efficiency.

[0109] continue Figure 12As shown, the pressing member further includes a fixing portion 183, which is located above the side of the crimping portion 181 facing the battery cover. The fixing portion 183 is connected to the battery cover, so that one end of the pressing member can be fixedly connected to the battery cover. Figure 11 As shown in FIG, the first pressing member 18 is connected to the first battery cover 14 via the fixing portion 183 .

[0110] Among them, see Figure 12 As shown, one end of the fixing portion 183 is connected to the abutting portion 182, and the other end of the fixing portion 183 extends toward the rotating assembly 13, thus forming a flange structure on the abutting portion 182. Specifically, the fixing portion 183 is located on the end of the abutting portion 182 facing away from the crimping portion 181, and the fixing portion 183 is a flange structure formed on this end and extends toward the rotating assembly 13. The connection between the battery cover and the fixing portion 183 has a large contact connection area, which helps to improve the connection strength between the pressing member and the battery cover.

[0111] The connection between the battery cover and the fixing portion 183 may be a glue point connection, a welding connection, a threaded fastening connection, or other connection methods.

[0112] Continue to see Figure 12 As shown, the pressing member is further provided with a support portion 184. One end of the support portion 184 is connected to the crimping portion 181, and the other end of the support portion 184 extends toward a side away from the crimping portion 181, and the other end of the support portion 184 extends below the door panel. Furthermore, the support portion 184 abuts against the door panel, supporting the door panel so that the door panel and the battery cover abut. This eliminates the gap 186 between the door panel and the battery cover, helping to reduce assembly tolerances and errors between the battery cover and the door panel, effectively improving the assembly accuracy of the door panel, the battery cover, and the pressing member, and enhancing the aesthetics and reliability of the electronic device 10.

[0113] At the same time, the support part 184 supports the door panel so that the door panel abuts against the battery cover, so that the door panel can provide support for the battery cover, reducing or avoiding the phenomenon of part of the battery cover hanging in the air, thereby reducing or avoiding the problem of pressing in the empty space when pressing on the battery cover area, thereby improving the user experience.

[0114] Combine Figure 11 and Figure 8 As shown, taking the first pressing member 18 as an example, one end of the supporting portion 184 of the first pressing member 18 is connected to the crimping portion 181, and the other end of the supporting portion 184 extends to the bottom of the first door panel 16. At the same time, the supporting portion 184 abuts against the first door panel 16 to support the first door panel 16, so that the first door panel 16 abuts against the first battery cover 14. The first door panel 16 provides support for the first battery cover 14, reducing or avoiding the problem of easy pressing of the empty position on the first battery cover 14.

[0115] The support portion 184 may include a connected connecting section 1842 and a supporting section 1841, one end of the connecting section 1842 is connected to the crimping portion 181, and the other end of the connecting section 1842 extends to the bottom of the door panel. The supporting section 1841 is located on the side of the other end of the connecting section 1842 facing the door panel, and the side of the supporting section 1841 facing away from the connecting section 1842 abuts against the door panel. In this way, the door panel is supported by the supporting section 1841 of the support portion 184, so that the door panel can abut against the battery cover.

[0116] Combine Figure 8 and Figure 11 As shown, taking the first clamping member 18 as an example, the supporting portion 184 of the first clamping member 18 includes a connecting segment 1842 and a supporting segment 1841, wherein one end of the connecting segment 1842 is connected to the crimping portion 181, and the other end of the connecting segment 1842 extends to the bottom of the first door panel 16, and the supporting segment 1841 located on the other end of the connecting segment 1842 abuts against the first door panel 16, thereby making the first door panel 16 abut against the first battery cover 14.

[0117] Among them, participants Figure 13 As shown, a gap 186 may be provided between the support section 1841 and the connecting section 1842, which can reduce the weight of the pressing member and contribute to the lightweight design of the electronic device 10. Specifically, the support section 1841 may be formed by bending the other end of the connecting section 1842 and extending toward the crimping portion 181.

[0118] The support portion 184 may further include an extension section 1843, which is located on the connecting section 1842. One end of the extension section 1843 is connected to the support section 1841, and the other end of the extension section 1843 extends toward the crimping portion 181 and ultimately connects thereto. Thus, the support section 1841 is connected to the crimping portion 181 via the extension section 1843 and the connecting section 1842, thereby increasing the support strength of the support section 184 on the door panel. Furthermore, the location of the extension section 1843 on the connecting section 1842 further strengthens the connection between the support section 1841 and the crimping portion 181, further increasing the support strength of the support section 184 on the door panel.

[0119] The electronic device 10 may further include a first fastener 130, a first assembly hole may be provided on the connecting section 1842, and a second assembly hole coaxial with the first assembly hole may be provided on the extending section 1843. Figure 11 and Figure 12As shown, one end of the first fastener 130 can abut against the support portion 184, and the other end of the first fastener can pass through the second assembly hole and the first assembly hole in sequence and then be connected to the connector of the structural member (such as the first connector 112), so that the support portion 184 can be connected to the connector. In this way, while fixing the clamping member, the supporting strength of the support portion 184 can be further improved.
