Description

Technical Field

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

[0002] A flexible screen refers to a screen that is flexible and can be bent or folded, so that more flexible and portable devices can be made. For example, as flexible screen technology gradually matures, the display method of terminal devices has undergone tremendous changes. One of them is the emergence of foldable mobile phones, computers and other electronic devices. Such electronic devices can flexibly switch modes according to different usage scenarios. At the same time, they also have a high screen-to-body ratio and clarity, making them one of the most sought-after products.

[0003] At present, electronic devices include a middle frame, and the flexible screen is usually mounted on the middle frame. The middle frame provides support and assembly space for the flexible screen. In order to meet the electromagnetic compatibility requirements of the flexible screen, the metal layer on the back of the flexible screen (the side facing the middle frame) needs to be electrically connected to the middle frame. For example, a conductive foam is arranged between the flexible screen and the middle frame, and the flexible screen and the middle frame are electrically connected through the conductive foam and grounded together. The conductive foam is usually compressed and arranged between the flexible screen and the middle frame. The compressed conductive foam provides a counter-top force to the flexible screen to ensure the reliability of the fixed assembly and electrical connection between the conductive foam and the flexible screen.

[0004] However, the counter-force of the conductive foam will cause local deformation of the flexible screen, making it easy for scratches to appear on the flexible screen and affecting the flatness of the flexible screen. Utility Model Content

[0005] An embodiment of the present application provides an electronic device that, while ensuring reliable assembly and electrical connection between a housing and a flexible screen, does not generate a reverse force on the flexible screen, thereby reducing or avoiding the problem of scratches on the flexible screen and improving the flatness of the flexible screen.

[0006] An electronic device provided in an embodiment of the present application includes a shell, a flexible screen and a retractable conductive member, wherein the flexible screen is arranged on the shell, the conductive member is located between the shell and the flexible screen, and the conductive member has a first end and a second end relative to each other in the retractable direction, and the first end and the second end are electrically connected to the shell and the flexible screen respectively, so that the flexible screen can be electrically connected to the shell through the conductive member.

[0007] The conductive part has a cavity, and the cavity is located between the first end and the second end. The flexible screen is used to drive the conductive part to stretch and contract through the second end to compress or expand the cavity. For example, during actual assembly, the flexible screen can be pressed along the thickness direction so that the flexible screen drives the second end of the conductive part to move toward the first end, and the conductive part contracts and compresses the cavity of the conductive part. When the conductive part is compressed to the limit, the cavity inside the conductive part is completely compressed. The flexible screen and the conductive part are stacked on the rigid shell, and the flexible screen and the conductive part, and the conductive part and the shell can be fully contacted and fixed, such as being fully extruded and bonded by conductive glue to achieve electrical connection. When the pressure on the flexible screen is removed, the flexible screen will move away from the shell, and drive the second end of the conductive part to move away from the first end, so that the conductive part stretches and expands the cavity inside the conductive part, and the fixation and electrical connection between the flexible screen and the conductive part, and the shell and the conductive part can still be ensured, thereby achieving stable assembly and electrical connection between the flexible screen, the conductive part and the shell, and ensuring the reliability of fixed assembly and electrical connection between the flexible screen and the shell. In addition, the conductive part does not exert any counter-force on the flexible screen, that is, while ensuring stable conduction between the flexible screen and the shell, the problem of causing scratches on the flexible screen is avoided, thereby significantly improving the flatness of the flexible screen.

[0008] In addition, the vertical projection area of ​​the conductive part along the thickness direction on the flexible screen is taken as the conduction area. In scenarios such as touch operation on the flexible screen, when a finger or a stylus passes over the conduction area on the flexible screen, the flexible screen drives the conductive part to shrink through the second end and compresses the cavity of the conductive part. For example, when the conductive part is compressed to the limit, the cavity inside the conductive part is completely compressed, and the flexible screen and the conductive part are stacked on the rigid shell, and the thickness is significantly reduced, so that no obvious local protrusions or bulges are formed on the flexible screen, which can ensure that the feel does not change significantly and does not affect the feel of the touch operation. The problem of abnormal feel during touch operation is solved and the user experience is improved.

[0009] In one possible implementation, a groove is provided on the side of the shell facing the flexible screen, and the first end of the conductive member is arranged in the groove. On the one hand, the groove can facilitate the assembly of the conductive member on the shell. On the other hand, in scenarios such as touch operation, when the conductive member is extremely compressed and in a contracted state, at least part of the conductive member can be accommodated in the groove, reducing the thickness space occupied by the conductive member above the shell (facing the side of the flexible screen), further reducing or avoiding the occurrence of local protrusions, bulges and other problems on the flexible screen, and ensuring that the feel is not affected.

[0010] In a possible implementation, when the conductive member is in a contracted state, the first end of the conductive member fits with the second end, and the side of the second end facing away from the first end is flush with the side of the housing facing the flexible screen. That is, when the conductive member is compressed to the limit, the thickness of the conductive member fills the depth (thickness) of the groove, so that the side of the second end facing away from the first end and the side of the housing facing the flexible screen basically form a plane without lifting, and no local protrusions or bulges will be formed on the flexible screen, ensuring that the hand feel does not change, further improving the user experience.

[0011] In a possible implementation, the conductive member is an annular structure with a cavity inside, and the structural design is simple, which helps to reduce the difficulty and cost of molding.

[0012] In a possible implementation, the conductive member includes a flexible conductive film, the conductive film encloses a cavity, part of the conductive film forms the first end, and part of the conductive film forms the second end. The conductive film itself is flexible, so that the conductive member can be bent, folded, or deformed under the action of an external force, such as driven by a flexible screen, thereby achieving expansion and contraction of the conductive member, and causing a change in the volume of the internal cavity during expansion and contraction, thereby achieving compression or expansion of the cavity.

[0013] In addition, the thickness of the conductive film itself is relatively small, and the conductive part formed can achieve ultra-thin thickness when it is compressed to the limit, further ensuring that no obvious protrusions, bulges, etc. will be formed on the flexible screen, which is more conducive to solving the problem of abnormal feel during touch operation.

[0014] In a possible implementation, the conductive film has a head end and a tail end in the extension direction, and the head end and the tail end of the conductive film are connected to enclose a cavity. The molding method is simple, the operation is convenient, and the production is easy to implement.

[0015] In one possible implementation, the portion where the head end and the tail end of the conductive film are connected is located at the first end or the second end of the conductive member. It is understandable that the first end and the second end of the conductive member are respectively connected to the housing and the flexible screen, and when the conductive member contracts, the portion between the first end and the second end of the conductive member is prone to deformation. The portion where the head end and the tail end of the conductive film are connected is located at the first end or the second end of the conductive member, and the portion between the head end and the tail end of the conductive film can form the portion between the first end and the second end of the conductive member, which can reduce or avoid deformation at the position where the head end and the tail end of the conductive film are connected, ensure the stability and reliability of the connection between the head end and the tail end, and reduce or avoid problems such as disconnection caused by deformation of the connection between the head end and the tail end due to contraction of the conductive member.

[0016] In one possible implementation, the head and tail ends of the conductive film are at least partially stacked in the telescopic direction so that there is a larger contact area between the head and tail ends, which is beneficial to improving the stability of the connection between the head and tail ends of the conductive film, thereby improving the reliability of the conductive component.

[0017] In a possible implementation, the overlapping area of ​​the head end and the tail end is located at the first end of the conductive member, and the vertical projection of the overlapping area of ​​the head end and the tail end along the extension direction coincides with the vertical projection of the second end of the conductive member along the extension direction. The thickness step difference of the film layer below the second end of the conductive member (the side facing away from the flexible screen along the extension direction) is reduced or avoided. When the conductive member is compressed to the limit, the thickness of the film layer below the second end of the conductive member is consistent, and both are film layers stacked at the head end and the tail end. This is more conducive to ensuring that the touch feel does not change when the touch operation passes through the conductive area, thereby improving the user experience.

[0018] In a possible implementation, the electronic device further includes an adhesive layer, and the adhesive layer is located between the head end and the tail end, so that the head end and the tail end are fixed together through the adhesive layer.

[0019] In a possible implementation, the electronic device further includes a first conductive adhesive layer, which is located between the first end of the conductive member and the shell, and the first end is electrically connected to the shell through the first conductive adhesive layer, thereby achieving fixation and electrical connection between the shell and the conductive member.

[0020] The electronic device further includes a second conductive adhesive layer, which is located between the second end of the conductive member and the flexible screen, and the second end is electrically connected to the flexible screen through the second conductive adhesive layer, thereby achieving fixation and electrical connection between the flexible screen and the conductive member. The connection structure is simple, easy to implement, and low in cost.

[0021] In a possible implementation, the conductive film includes conductive cloth and metal film. The conductive part is formed by a thin layer structure such as a conductive metal film or conductive cloth. For example, the head and tail ends of the metal film or conductive cloth are connected to form a conductive part with a cavity inside, which meets the expansion and contraction and conductivity requirements of the conductive part. The structural design is simple and easy to assemble, which is conducive to improving assembly efficiency and reducing production costs.

[0022] In a possible implementation, the conductive film includes a flexible film layer and a conductive layer, the conductive layer is arranged on a side of the flexible film layer facing away from the cavity, and the conductive layer extends at least from the first end to the second end of the conductive member. It is flexible and can give the conductive film flexibility to achieve the expansion and contraction of the conductive member. The conductive layer has conductivity and can give the conductive film conductivity to meet the electrical connection between the first end and the second end of the conductive member and the housing and the flexible screen. Enriching the structural design of the conductive film allows the conductive member to have better structural flexibility, which helps to expand the scope of application of the conductive member.

[0023] In a possible implementation, the conductive layer completely covers the side of the flexible film layer facing away from the cavity, so that the thickness of the entire conductive film remains consistent, which is more conducive to achieving the effect of no change in touch feeling when the touch operation passes through the conductive area.

[0024] In a possible implementation, the conductive layer includes a conductive adhesive, part of the conductive adhesive forms a first conductive adhesive layer, part of the conductive adhesive forms a second conductive adhesive layer, and part of the conductive adhesive forms an adhesive layer. That is, when a conductive film is used to enclose a conductive part, the conductive adhesive included in the conductive film itself can be used to bond the head end and the tail end of the conductive film, and the conductive part can also be directly bonded and fixed to the housing and the flexible screen through the conductive adhesive, without the need to set up an adhesive layer and a conductive adhesive layer. The molding and operation methods of the conductive part are simple, the molding difficulty, i.e., the cost, is low, and it is easy to produce.

[0025] In a possible implementation, the flexible film layer includes conductive cloth, a metal film, and a polyimide film.

[0026] In a possible implementation, the conductive film on the first end has a first through hole. For example, in an example where the conductive film is a conductive cloth, the conductive cloth is woven from fibers with gaps between the fibers, so that the conductive film on the first end of the conductive member has a first through hole.

[0027] The electronic device further includes a first anti-seepage layer, which is arranged on a side of the first end facing the cavity, and covers the first through hole. The first anti-seepage layer can prevent the first conductive adhesive layer and the adhesive layer from overflowing through the first through hole to the side of the first end facing the cavity, avoid the adhesion problem between the first end and the second end of the conductive member when it is extremely compressed, and improve the flatness of the flexible screen.

[0028] In a possible implementation, the conductive film on the second end has a second through hole, and the electronic device further includes a second anti-seepage layer, which is disposed on a side of the second end facing the cavity, and covers the second through hole. The second anti-seepage layer can prevent the second conductive adhesive layer from overflowing through the second through hole to the side of the second end facing the cavity, and can also prevent the adhesion problem between the first end and the second end of the conductive member when it is extremely compressed.

[0029] In a possible implementation, the housing includes at least a first middle frame and a second middle frame, and the electronic device further includes a hinge assembly, the first middle frame and the second middle frame are located on both sides of the hinge assembly, and the first middle frame and the second middle frame are rotatably connected through the hinge assembly, so that the first middle frame and the second middle frame can rotate relative to each other, that is, the housing can achieve a folding or unfolding opening and closing movement. The flexible screen is arranged on one side of the first middle frame, the second middle frame and the hinge assembly, and the flexible screen can be folded or unfolded with the movement of the housing, so that the electronic device can switch between a folded state and a flattened state.

[0057] 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.

[0058] An embodiment of the present application provides an electronic device having a flexible screen. Exemplarily, the electronic device may be an electronic device with a foldable screen. For example, the foldable electronic device may include but is not limited to a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen television, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, a vehicle-mounted device, and other foldable fixed terminals or mobile terminals.

[0059] Of course, in some examples, the electronic device may also be an electronic device with a non-foldable screen, for example, it may be a candy-bar mobile phone with a flexible screen, a laptop or tablet computer with a flexible screen, etc.

[0060] Among them, in the scenario where the electronic device is a foldable electronic device, the electronic device can be a foldable device with a screen folded outward, or the electronic device can also be a foldable device with a screen folded inward, or the electronic device can also be a foldable device with a partial screen folded inward and a partial screen folded outward, or the electronic device can also be a foldable device with a screen folded inward and an additional external screen, etc.

[0061] In the embodiments of the present application, the electronic device is a foldable mobile phone with a foldable screen.

[0062] Figure 1A schematic diagram of the structure of an electronic device in a folded state provided in an embodiment of the present application.

[0063] See also Figure 1 As shown, the electronic device 100 may include a shell 10 and a flexible screen 20. The flexible screen 20 is assembled on the shell 10. The flexible screen 20 and the shell 10 may enclose a receiving space, and the receiving space may be used to assemble and accommodate various functional components of the electronic device 100.

[0064] Exemplarily, the flexible screen 20 can be located on one side surface of the shell 10. The flexible screen 20 is the display screen of the electronic device 100, which is used to display images, text, videos, etc., and provide an interactive interface for users. The side of the flexible screen 20 facing away from the shell 10 can be used as the display surface of the electronic device 100.

[0065] The flexible screen 20 refers to a display screen that is flexible. Flexible can also be interpreted as flexibility, which means that an object is easily deformed after being subjected to force, so that it can be freely bent, rolled, and folded. The flexible screen 20 may include, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro organic light-emitting diode display screen, or a quantum dot light emitting diode (QLED) display screen, etc.

[0066] The housing 10 may include a plurality of middle frames 101. For example, the number of the middle frames 101 is two, such as a first middle frame 101a and a second middle frame 101b. The electronic device 100 also includes a hinge assembly 30. The first middle frame 101a and the second middle frame 101b may be located on both sides of the hinge assembly 30. The first middle frame 101a and the second middle frame 101b are connected to the hinge assembly 30 respectively.

[0067] The hinge assembly 30 may be a structural assembly used to connect the two middle frames 101 and allow the two middle frames 101 to rotate relative to each other. The first middle frame 101a and the second middle frame 101b may be rotated together through the hinge assembly 30, so that the first middle frame 101a and the second middle frame 101b may rotate relative to each other, so that the housing 10 may be folded or unfolded, and the flexible screen 20 may be folded or unfolded with the movement of the housing 10, so that the electronic device 100 may switch between the folded state and the flattened state.

[0068] The flexible screen 20 can be set on the hinge assembly 30 and the middle frame 101. For example, the flexible screen 20 can be located on the same side of the first middle frame 101a, the second middle frame 101b and the hinge assembly 30. The part of the flexible screen 20 opposite to the first middle frame 101a can be laid flat on the first middle frame 101a, and the part of the flexible screen 20 opposite to the second middle frame 101b can be laid flat on the second middle frame 101b.

[0069] The first middle frame 101a and the second middle frame 101b can be folded relatively to a closed state. Figure 1 As shown, illustratively, when the first middle frame 101a and the second middle frame 101b are in a closed state, the two can be completely folded to be parallel to each other (a slight deviation is allowed), and the electronic device 100 is in a closed state as a whole, also called a folded state. The part of the flexible screen 20 opposite to the hinge assembly 30 is bent and in a folded state.

[0070] Figure 2 for Figure 1 A schematic diagram of the structure of the electronic device shown is in an intermediate state.

[0071] See also Figure 2 As shown, the first middle frame 101a and the second middle frame 101b can be relatively rotated (folded or unfolded) to an intermediate state, so that the electronic device 100 is in the intermediate state. The part of the flexible screen 20 opposite to the hinge assembly 30 is also folded or unfolded to the intermediate state.

[0072] Figure 3 for Figure 1 The schematic diagram of the structure of the electronic device shown is in a flattened state.

[0073] See also Figure 3As shown, the first middle frame 101a and the second middle frame 101b can be relatively unfolded to an open state. Exemplarily, the first middle frame 101a and the second middle frame 101b are in an open state, and the unfolding angle between the first middle frame 101a and the hinge assembly 30, and the unfolding angle between the hinge assembly 30 and the second middle frame 101b can be approximately 180°, and the electronic device 100 is in an open state as a whole, also called a flattened state. The part of the flexible screen 20 opposite to the hinge assembly 30 is also opened and flattened, that is, the flexible screen 20 as a whole can be flattened into a plane of approximately 180°.

[0074] It should be noted that the angles described in the embodiments of the present application are allowed to have slight deviations. For example, Figure 3 The unfolding angle of the electronic device 100 (or the flattening angle of the flexible screen 20) can be 180°, or approximately 180°, such as 170°, 175°, 185° or 190°, etc. The angles exemplified below can be understood in the same way.

[0075] in, Figure 2 The intermediate state shown can be any state between the folded state and the flattened state. That is, the housing 10 and the flexible screen 20 of the electronic device 100 can switch between the flattened state (i.e., the open state) and the folded state (i.e., the closed state) through the movement of the hinge assembly 30, thereby realizing the opening and closing of the electronic device 100.

[0076] For example, when the electronic device 100 is in the flattened state, the first middle frame 101a and the second middle frame 101b are rotated toward each other and relatively folded, so that the electronic device 100 can be switched from the flattened state to the folded state (or the intermediate state). When the electronic device 100 is in the folded state, the first middle frame 101a and the second middle frame 101b are rotated away from each other and relatively unfolded, so that the electronic device 100 can be switched from the folded state to the flattened state (or the intermediate state).

[0077] For example, for a foldable electronic device with a foldable screen, the flexible screen 20 can be disposed on the outer surfaces of the first middle frame 101a, the second middle frame 101b, and the hinge assembly 30. For a foldable electronic device with a foldable screen, the flexible screen 20 can be disposed on the inner surfaces of the first middle frame 101a, the second middle frame 101b, and the hinge assembly 30.

[0078] When the electronic device 100 is in a folded state, the two adjacent and opposite surfaces of the first middle frame 101a and the second middle frame 101b can be the inner surfaces of the first middle frame 101a and the second middle frame 101b, respectively, and the surface of the hinge assembly 30 located on the same side as the inner surfaces of the first middle frame 101a and the second middle frame 101b is the inner surface of the hinge assembly 30. The two opposite surfaces of the first middle frame 101a and the second middle frame 101b are the outer surfaces of the first middle frame 101a and the second middle frame 101b, respectively, and the surface of the hinge assembly 30 located on the same side as the outer surfaces of the first middle frame 101a and the second middle frame 101b is the outer surface of the hinge assembly 30.

[0079] For example, the middle frame 101 may be a rectangular flat plate structure. In the embodiment of the present application, Figure 3 As shown, the width direction of the middle frame 101 (such as the first middle frame 101a) is the x direction, the length direction of the middle frame 101 is the y direction, and the thickness direction of the middle frame 101 is the z direction. It can be understood that the length, width, and thickness in the embodiment of the present application are only for the convenience of description and do not mean any limitation on the size. For example, the length can be greater than, equal to, or less than the width. It can be understood that when the foldable electronic device 100 is in a folded state or a flattened state, the length direction, width direction, and thickness direction of the electronic device 100 can correspond to the length direction, width direction, and thickness direction of the middle frame 101.

[0080] Of course, in some other examples, the middle frame 101 may also be a flat plate structure in a square, circular, oval, rounded rectangular, or other shape.

[0081] It should be noted that the electronic device 100 may include only two middle frames 101, such as the first middle frame 101a and the second middle frame 101b may both be one, so that the electronic device 100 is in a folded state, and the first middle frame 101a and the second middle frame 101b are relatively folded into two layers. Figure 1 As shown, the electronic device 100 includes a first middle frame 101a, a second middle frame 101b and a hinge assembly 30. The first middle frame 101a and the second middle frame 101b are rotatably connected via the hinge assembly 30. When the first middle frame 101a and the second middle frame 101b are folded relative to each other and are in a folded state, the electronic device 100 is in the form of two layers of middle frames 101 stacked.

[0082] Alternatively, the electronic device 100 may also include a plurality of middle frames 101, such as the number of the first middle frame 101a, the second middle frame 101b and the hinge assembly 30 may be multiple, and the adjacent first middle frames 101a and the second middle frames 101b may be connected by a hinge assembly 30, so that the electronic device 100 can be folded into a multi-layered form. For example, the electronic device 100 may include two first middle frames 101a, one second middle frame 101b and two hinge assemblies 30, the two first middle frames 101a are located on both sides of the second middle frame 101b, and the two first middle frames 101a are respectively connected to the second middle frame 101b by a hinge assembly 30, one of the first middle frames 101a can be folded relative to the second middle frame 101b, and the other first middle frame 101a can also be folded relative to the second middle frame 101b, so that the electronic device 100 is in a folded state, and the first middle frame 101a and the second middle frame 101b are folded relative to each other to form a three-layer stacked form of the middle frame 101. When one of the first middle frame 101 a and the second middle frame 101 b is relatively unfolded to a flat state, the electronic device 100 is in a flat state.

[0083] It can be understood that in some other examples, such as the three-middle-frame folding electronic device 100 mentioned above, the flexible screen 20 is arranged on two first middle frames 101a, one second middle frame 101b and a hinge assembly 30, and part of the flexible screen 20 can be located on the inner surface of one of the first middle frames 101a, one of the hinge assemblies 30 and the second middle frame 101b, and part of the flexible screen 20 can be located on the outer surface of another first middle frame 101a.

[0084] In the embodiment of the present application, an electronic device 100 includes two middle frames, a first middle frame 101a and a second middle frame 101b, and the first middle frame 101a and the second middle frame 101b are rotatably matched through a hinge assembly 30 as an example for description.

[0085] In some other examples, the foldable electronic device 100 may also be a laptop computer, which may include a first middle frame 101a and a second middle frame 101b, which may be relatively folded to a closed state, so that the laptop computer is in a closed state (i.e., a folded state). Accordingly, the first middle frame 101a and the second middle frame 101b are relatively unfolded from the folded state to an open state, and the laptop computer is in an open state (i.e., a flattened state). In the flattened state, at least part of the flexible screen on the first middle frame 101a can be used to display images, etc., and at least part of the flexible screen on the second middle frame 101b can be used as a virtual keyboard, etc.

[0086] Figure 4 for Figure 1 Schematic diagram of the disassembled structure of the electronic device shown.

[0087] See also Figure 4 As shown, the shell 10 may also include a back cover 40. The flexible screen 20 and the back cover 40 may be respectively located on opposite sides of the middle frame 101 and the hinge assembly 30 along the thickness direction (z direction). The back cover 40, the flexible screen 20 and the middle frame 101 together enclose the above-mentioned accommodating space.

[0088] The back cover 40 can serve as an appearance cover on the back of the electronic device 100 , protecting the functional components inside the electronic device 100 (such as a circuit board and a battery, etc.) and improving the aesthetics of the electronic device 100 .

[0089] The middle frame 101 may include a middle plate and a frame. For example, the first middle frame 101a may include a first middle plate 1012 and a first frame 1011, and the first frame 1011 is arranged on the outer peripheral edge of the first middle plate 1012. The second middle frame 101b may also include a second middle plate 1013 and a second frame 1014, and the second frame 1014 is arranged on the outer peripheral edge of the second middle plate 1013. The hinge assembly 30 may be connected to the first middle plate 1012 and the second middle plate 1013, respectively.

[0090] The flexible screen 20 is disposed on the middle frame 101. For example, part of the flexible screen 20 can be fixed to the frame, and part of the flexible screen 20 can be fixed to the middle plate.

[0091] It should be noted that the middle plate and the frame can be formed separately, and the middle plate and the frame can be fixedly assembled together by welding, clamping, bonding, etc. Alternatively, the middle plate and the frame can also be formed in one piece.

[0092] The molding material of the middle frame 101 may include metal. Of course, in some examples, the molding material of the middle frame 101 may also include ceramic, glass, etc.

[0093] The electronic device 100 may also include a circuit board, a battery, a charging management module, a power management module, etc. (not shown in the figure), and the circuit board, the battery, the charging management module, the power management module, etc. may be fixed in the above-mentioned accommodation space.

[0094] The circuit board may include a processor, and the processor may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, a display processing unit (DPU), and / or a neural-network processing unit (NPU). Among them, the controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions. A memory may also be provided in the processor 110 for storing instructions and data.

[0095] The processor may include one or more interfaces, which can be used to connect a charger to charge the electronic device 100. The interface can also be used to implement data transmission between the electronic device 100 and an external device, for example, it can also be used to connect headphones, projection devices, etc.

[0096] The charging management module is used to receive charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging examples, the charging management module can receive charging input from the wired charger through an interface. In some wireless charging embodiments, the charging management module can receive wireless charging input through a wireless charging coil of the electronic device 100. The charging management module can charge the battery and can also power the electronic device 100 through the power management module.

[0097] The power management module is used to connect the battery, charging management module and processor. The power management module receives input from the battery and / or charging management module to power the processor, memory, display screen, camera module, etc. The power management module can also be used to monitor parameters such as battery capacity, battery cycle number, battery health status (leakage, impedance), etc.

[0098] In some examples, the power management module can be disposed in a processor of the circuit board. In other examples, the power management module and the charging management module can also be disposed in the same device.

[0099] The structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. For example, the electronic device 100 may also include a communication module, a camera module (such as a front camera and a rear camera), a microphone, a speaker, a flash, and other devices.

[0100] Among them, the side of the flexible screen 20 facing the shell 10 has a metal layer. The flexible screen 20 needs to be electrically connected to the metal structure of the shell 10 through the metal layer and grounded together to meet the electromagnetic compatibility requirements of the flexible screen 20. For example, the metal layer of the flexible screen 20 can be electrically connected to the metal middle frame 101 of the shell 10 to achieve electrical connection between the flexible screen 20 and the shell 10.

[0101] In some examples, the flexible screen can be electrically connected to the middle frame of the shell through conductive foam. For example, conductive foam is arranged between the flexible screen and the middle plate of the shell, and the two ends of the conductive foam can be electrically connected to the flexible screen and the middle plate respectively through conductive glue, thereby realizing the electrical connection between the flexible screen and the middle plate. In order to ensure stable conduction between the flexible screen and the conductive foam, during actual assembly, the conductive foam needs to be compressed and placed on the side of the middle plate facing the flexible screen, and then the flexible screen is laid on the compressed conductive foam. The rebound force of the conductive foam will form a counter-force on the flexible screen, ensuring the fixation of the conductive foam and the flexible screen and the stability of the electrical connection.

[0102] However, the counter-force of the conductive foam on the flexible screen can easily cause local deformation of the flexible screen, resulting in spots on the flexible screen and affecting the flatness of the flexible screen. In addition, the vertical projection area (along the thickness direction) of the conductive foam on the flexible screen is taken as the conductive area. When a finger or a stylus passes through the conductive area on the flexible screen during touch operation, the conductive foam will be compressed. Even if the conductive foam is compressed to the maximum extent, the conductive foam itself is relatively thick, and obvious local bulges and bulges will form in the conductive area, affecting the touch feel and reducing the user experience.

[0103] Based on this, an embodiment of the present application provides an electronic device, by arranging a retractable conductive part between a shell and a flexible screen, the two opposite ends of the conductive part along the retracting direction are electrically connected to the shell and the flexible screen respectively, the conductive part has a cavity, and the flexible screen can drive the conductive part to retract and compress or expand the cavity. During actual assembly, the flexible screen can be pressed so that the flexible screen drives the second end of the conductive part to move toward the first end, the conductive part contracts and compresses the cavity of the conductive part, and when the conductive part is compressed to the limit, the internal cavity is completely compressed, and the flexible screen and the conductive part, and the conductive part and the shell can be fully contacted and fixed, such as being fully extruded and bonded by conductive glue to achieve electrical connection. When the pressure on the flexible screen is removed, the flexible screen will move away from the shell to drive the second end of the conductive part to move away from the first end, and the conductive part stretches and expands the cavity, which can still ensure the fixation and electrical connection between the flexible screen, the conductive part and the shell, thereby achieving reliable assembly and electrical connection between the flexible screen and the shell. In addition, the conductive parts do not have any counter-force on the flexible screen. While ensuring stable conduction between the flexible screen and the shell, the problem of causing scratches on the flexible screen is avoided, thereby improving the flatness of the flexible screen.

[0104] In addition, in scenarios such as touch operations on flexible screens, when a finger or a stylus slides over the conductive area on the flexible screen corresponding to the conductive part, the flexible screen will drive the conductive part to shrink and compress the cavity. For example, when the conductive part is compressed to the limit, the cavity can be completely compressed. The flexible screen and the conductive part are stacked on the rigid shell, and the thickness is significantly reduced, so that no obvious local protrusions or bulges will be formed on the flexible screen, ensuring that there is no obvious change in the feel, solving problems such as abnormal feel during touch operations, and improving the user experience.

[0105] Figure 5 A schematic diagram of a partial cross-sectional structure of an electronic device provided in an embodiment of the present application.

[0106] See also Figure 5 As shown, the electronic device 100 includes a housing 10, a flexible screen 20 and a conductive member 50. The conductive member 50 refers to a structural member that allows current to pass through and is easily conductive. For example, the molding material of the conductive member 50 may include conductive materials such as metals.

[0107] The conductive member 50 is located between the flexible screen 20 and the housing 10. Exemplarily, the conductive member 50 can be arranged between the flexible screen 20 and the metal structure of the housing 10, for example, the conductive member 50 can be arranged between the flexible screen 20 and the middle plate of the middle frame 101. The flexible screen 20 has a metal layer (not shown in the figure) on the side facing the housing 10. The metal layer of the flexible screen 20 can be electrically connected to the metal structure of the housing 10 through the conductive member 50, thereby achieving conduction between the flexible screen 20 and the housing 10. For example, the flexible screen 20 can be grounded through the metal structure of the housing 10 to meet the electromagnetic compatibility requirements of the flexible screen 20.

[0108] The conductive member 50 is retractable. It can be understood that Figure 5 As shown, the flexible screen 20 can be located on one side of the housing 10 along the thickness direction (z direction), and the expansion and contraction direction of the conductive member 50 can be consistent with the thickness direction, such as Figure 5 The z direction shown in .

[0109] The two opposite ends of the conductive member 50 along the extension direction (z direction) can be the first end 50a and the second end 50b respectively. The first end 50a and the second end 50b can be electrically connected to the shell 10 and the flexible screen 20 respectively. For example, the end face of the first end 50a of the conductive member 50 can be fixed to the shell 10 and electrically connected through a first conductive adhesive layer (not shown in the figure), and the end face of the second end 50b of the conductive member 50 can also be fixed to the flexible screen 20 and electrically connected through a second conductive adhesive layer (not shown in the figure).

[0110] The conductive member 50 may also have a cavity 51, for example Figure 5 As shown, the conductive member 50 may be a hollow structure, so that the conductive member 50 has a cavity 51 inside, and the cavity 51 can be compressed or expanded as the conductive member 50 expands and contracts. Exemplarily, the flexible screen 20 may act on the second end 50b of the conductive member 50 to drive the second end 50b to move toward or away from the first end 50a, thereby realizing the expansion and contraction of the conductive member 50 and compressing or expanding the cavity 51 between the first end 50a and the second end 50b.

[0111] In the embodiment of the present application, when the conductive member 50 is extremely compressed, that is, the conductive member 50 is compressed to the maximum extent, the conductive member 50 is in a contracted state, the first end 50a and the second end 50b of the conductive member 50 can be fitted together, and there is no gap between the first end 50a and the second end 50b, so that the cavity 51 inside the conductive member 50 is completely compressed.

[0112] For example, during actual assembly, the conductive member 50 is fixed between the shell 10 and the flexible screen 20, a first conductive adhesive layer (not shown in the figure) may be provided between the end surface of the first end 50a of the conductive member 50 and the shell 10, and a second conductive adhesive layer (not shown in the figure) may be provided between the end surface of the second end 50b of the conductive member 50 and the flexible screen 20. The flexible screen 20 can be pressed along the thickness direction (z direction), and the flexible screen 20 drives the second end 50b of the conductive member 50 to move toward the first end 50a, so that the conductive member 50 shrinks and compresses the cavity 51. When the conductive member 50 is compressed to the limit, the cavity 51 inside the conductive member 50 is completely compressed, so that the flexible screen 20, the conductive member 50 and the shell 10 can be fully contacted and fixed. For example, the flexible screen 20, the second conductive adhesive layer, the conductive member 50 and the first conductive adhesive layer are stacked on the rigid shell 10 in sequence, and the flexible screen 20 and the conductive member 50 can be fully extruded and bonded with the second conductive adhesive layer to achieve electrical connection, and the shell 10 and the conductive member 50 can also be fully extruded and bonded with the first conductive adhesive layer to achieve electrical connection.

[0113] When the pressure on the flexible screen 20 is removed, the flexible screen 20 will move away from the housing 10 to reset. The flexible screen 20 and the second end 50b of the conductive member 50 are bonded and fixed together by the second conductive adhesive layer. The flexible screen 20 will drive the second end 50b of the conductive member 50 to move away from the first end 50a, so that the conductive member 50 stretches and expands the cavity 51, and the fixation and electrical connection between the flexible screen 20 and the conductive member 50, and the housing 10 and the conductive member 50 can still be ensured, thereby achieving stable assembly and electrical connection between the flexible screen 20, the conductive member 50 and the housing 10, and ensuring the reliability of the fixed assembly and electrical connection between the flexible screen 20 and the housing 10. In addition, the conductive member 50 does not have a counter-force on the flexible screen 20, that is, under the condition of ensuring stable conduction between the flexible screen 20 and the housing 10, the problem of causing marks on the flexible screen 20 is avoided, and the flatness of the flexible screen 20 is significantly improved.

[0114] In addition, the vertical projection area of ​​the conductive member 50 on the flexible screen 20 along the thickness direction is taken as the conductive area. In the scene of touch operation on the flexible screen 20, when a finger or a stylus passes over the conductive area on the flexible screen 20, the flexible screen 20 drives the conductive member 50 to shrink and compress the cavity 51 through the second end 50b. For example, when the conductive member 50 is extremely compressed, the cavity 51 inside the conductive member 50 is completely compressed, and the flexible screen 20 and the conductive member 50 are stacked on the rigid shell 10, and the thickness is significantly reduced, so that no obvious local protrusions, bulges, etc. are formed on the flexible screen 20, which can ensure that the feel does not change significantly, that is, it is ensured that the feel of the touch operation is not affected, solve the problem of abnormal feel during touch operation, and improve the user experience.

[0115] To further improve the operating feel, see Figure 5As shown, in some examples, a groove 11 may be provided on the side of the shell 10 facing the flexible screen 20 , and the first end 50 a of the conductive member 50 may be disposed in the groove 11 . On the one hand, the groove 11 may facilitate the assembly of the conductive member 50 on the shell 10 .

[0116] On the other hand, in scenarios such as touch operations, for example, when the conductive part 50 is extremely compressed and in a contracted state, at least part of the conductive part 50 can be accommodated in the groove 11, reducing the thickness space occupied by the conductive part 50 above the shell 10 (facing the side of the flexible screen 20), further reducing or avoiding local protrusions, bulges and other problems on the flexible screen 20, and ensuring that the feel is not affected.

[0117] Exemplarily, when the conductive member 50 is in a contracted state, the side of the second end 50b of the conductive member 50 facing away from the first end 50a can be flush with the side of the shell 10 facing the flexible screen 20, that is, when the conductive member 50 is compressed to the limit, the thickness of the conductive member 50 (the distance between the first end 50a and the second end 50b) fills the depth (thickness) of the groove 11, so that the side of the second end 50b facing away from the first end 50a and the side of the shell 10 facing the flexible screen 20 basically form a plane without lifting, and no local protrusions, bulges, etc. will be formed on the flexible screen 20, thereby ensuring that the hand feel does not change, further improving the user experience.

[0118] Figure 6 A schematic diagram of the structure of a conductive member provided in an embodiment of the present application.

[0119] Among them, see Figure 6 As shown, the conductive member 50 may be an annular structure, and the annular conductive member 50 has a cavity 51 inside. It is understandable that Figure 6 As shown in the figure, the cross section of the conductive member 50 may be a closed ring, and the cavity 51 inside the conductive member 50 has a continuous cavity wall in the circumferential direction. For example, the overall extension direction of the conductive member 50 is parallel to the length direction of the electronic device 100, such as the y direction in the figure. In the y direction, the cavity 51 may have openings on opposite sides.

[0120] Exemplarily, the cross-section of the conductive member 50 may be in the shape of a regular or irregular shape such as a circular ring, a rectangular ring, a rounded rectangular ring, an elliptical ring, or a trapezoidal ring.

[0121] Of course, in some examples, the cross-section of the conductive member 50 may also be a non-closed ring. For example, the cross-section of the conductive member 50 may be a semicircular ring, a U-shaped ring, and so on.

[0122] The following uses the conductive member 50 having a closed ring structure as an example to describe the conductive member 50 in detail.

[0123] In some examples, the conductive member may include a flexible conductive film, and the conductive film may be used to enclose a conductive member having a cavity therein.

[0124] For example, see Figure 6 As shown, the conductive member 50 includes a conductive film 52, which can enclose a conductive member 50 having a cavity 51 inside. The conductive film 52 can form a cavity wall of the cavity 51, part of the conductive film 52 forms the first end 50a of the conductive member 50, and part of the conductive film 52 forms the second end 50b of the conductive member 50.

[0125] The conductive film 52 is flexible, and the enclosed conductive member 50 is hollow inside and has a cavity 51, so that the conductive member 50 can be bent, folded, or deformed under the action of an external force, such as driven by the flexible screen 20, and the conductive member 50 can be extended or retracted, such as by making the second end 50b and the first end 50a of the conductive member 50 move relative to each other to achieve the extension or retraction of the conductive member 50. When the conductive member 50 is extended or retracted, the volume of the internal cavity 51 changes, thereby compressing or expanding the cavity 51.

[0126] A conductive part 50 with a cavity 51 inside is formed by utilizing a conductive film 52. The thickness of the conductive film 52 itself is relatively small. When the conductive part 50 is compressed to the limit, the thickness of the conductive part 50 can be ultra-thin, further ensuring that no obvious protrusions or bulges are formed on the flexible screen 20, and being more conducive to solving the problem of abnormal feel during touch operation.

[0127] Exemplarily, the thickness of the conductive film 52 may be 0.02 mm to 0.2 mm, which is conducive to achieving ultra-thinness of the conductive element 50 when it is extremely compressed, ensuring that the hand feel is not affected.

[0128] In some examples, the conductive member 50 having the cavity 51 therein can be integrally formed when the conductive film 52 is molded.

[0129] Alternatively, in some examples, the conductive film 52 may be formed first, and then the conductive member 50 having the cavity 51 therein may be surrounded by the conductive film 52 .

[0130] Figure 7 A schematic top view of a conductive film provided in an embodiment of the present application.

[0131] For example, see Figure 7 As shown, before the conductive element 50 is formed, the edge contour of the conductive film 52 may be in the shape of a rectangle, and the conductive element 50 may be surrounded by the conductive film 52 .

[0132] For example, the extending direction of the conductive film 52 is parallel to the length direction of the rectangular conductive film 52. Figure 7In the L direction shown in FIG. 1 , in the extending direction, the conductive film 52 may have a head end 52a and a tail end 52b. Figure 7 The dotted line shown in the figure is a fold line. By folding the rectangular conductive film 52 and connecting the head end 52a and the tail end 52b of the conductive film 52 together, a conductive member 50 (such as Figure 6 The molding method is simple, the operation is convenient, and the production is easy to realize.

[0133] Of course, in some other examples, before forming the conductive member 50 , the edge contour of the conductive film 52 may also be a regular or irregular shape such as a trapezoid, an ellipse, or a circle.

[0134] It can be understood that the first end 50a and the second end 50b of the conductive member 50 are connected to the housing 10 and the flexible screen 20 respectively. When the conductive member 50 shrinks, the portion between the first end 50a and the second end 50b of the conductive member 50 is prone to deformation. Therefore, when the conductive member 50 is surrounded by the conductive film 52, the portion where the head end 52a and the tail end 52b of the conductive film 52 are connected can be located at the first end 50a or the second end 50b of the conductive member 50, and the portion between the head end 52a and the tail end 52b of the conductive film 52 can form the portion between the first end 50a and the second end 50b of the conductive member 50, which can reduce or avoid the deformation at the position where the head end 52a and the tail end 52b of the conductive film 52 are connected, ensure the stability and reliability of the connection between the head end 52a and the tail end 52b, and reduce or avoid the problems such as disconnection caused by deformation of the connection between the head end 52a and the tail end 52b due to the shrinkage of the conductive member 50.

[0135] Exemplarily, the portion where the head end 52a and the tail end 52b of the conductive film 52 are connected can be located at the first end 50a of the conductive member 50, that is, the portion where the head end 52a and the tail end 52b are connected is located at the end where the conductive member 50 is fixed to the shell 10, thereby avoiding the formation of bulges on the flexible screen 20 due to the different thicknesses of the connection portion between the head end 52a and the tail end 52b, which further helps to improve the flatness of the flexible screen 20.

[0136] Of course, in some examples, the portion where the head end 52 a and the tail end 52 b of the conductive film 52 are connected may also be located at the second end 50 b of the conductive member 50 .

[0137] Figure 8 A cross-sectional schematic diagram of a conductive member provided in an embodiment of the present application. Figure 8 The surface of the conductive member 50 cut along a plane parallel to the thickness direction (z direction) is shown.

[0138] In some examples, the head end 52a and the tail end 52b of the conductive film 52 can be stacked and fixed together, for example, see Figure 8 As shown, taking the example that the portion where the head end 52a and the tail end 52b are connected is located at the first end 50a of the conductive member 50, the head end 52a and the tail end 52b of the conductive film 52 are at least partially overlapped in the extension direction (z direction), that is, the projection of the head end 52a along the extension direction and the projection of the tail end 52b along the extension direction at least partially overlap. This allows a larger contact area between the head end 52a and the tail end 52b, which helps to improve the stability of the connection between the head end 52a and the tail end 52b of the conductive film 52, thereby improving the reliability of the conductive member 50.

[0139] Of course, in some examples, the head end 52a and the tail end 52b of the conductive film 52 can also be aligned and spliced ​​together so that the head end 52a and the tail end 52b are not overlapped. Figure 7 The end surface of the head end 52a of the conductive film 52 that is away from the tail end 52b in the extension direction is the end surface of the head end 52a, and the end surface of the tail end 52b of the conductive film 52 that is away from the head end 52a in the extension direction is the end surface of the tail end 52b. The end surface of the head end 52a and the end surface of the tail end 52b of the conductive film 52 are attached and fixed together to form a conductive member 50, so that the projections of the head end 52a and the tail end 52b of the conductive film 52 in the extension direction do not overlap, and the portion where the head end 52a and the tail end 52b are connected can form a plane.

[0140] It is understandable that the portion where the head end 52a and the tail end 52b of the conductive film 52 are connected is located at the first end 50a of the conductive member 50. Exemplarily, the entire head end 52a and the tail end 52b of the conductive film 52 may be connected to form the first end 50a of the conductive member 50, or part of the head end 52a and part of the tail end 52b may be connected to form the first end 50a of the conductive member 50.

[0141] The head end 52a and the tail end 52b of the conductive film 52 are stacked, and the vertical projection of the head end 52a along the extension direction and the vertical projection of the tail end 52b along the extension direction at least partially overlap, and the overlapping portion can be the overlapping area of ​​the head end 52a and the tail end 52b, such as Figure 8 The overlapping area S shown in FIG. 5A and 5B may also be located at the first end 50 a of the conductive member 50 .

[0142] The vertical projection of the overlapping area of ​​the head end 52a and the tail end 52b along the extension direction (z direction) can coincide with the vertical projection of the second end 50b of the conductive member 50 along the extension direction, thereby reducing or avoiding the thickness step difference of the film layer below the second end 50b of the conductive member 50 (the side facing away from the flexible screen 20 along the extension direction). When the conductive member 50 is compressed to the limit, the thickness of the film layer below the second end 50b of the conductive member 50 is consistent, and both are film layers stacked at the head end 52a and the tail end 52b. This is more conducive to ensuring that the feel remains unchanged when the touch operation passes through the conductive area, thereby improving the user experience.

[0143] For example, the head end 52a and the tail end 52b of the conductive film 52 can be connected by bonding to form the conductive member 50. For example, the head end 52a and the tail end 52b of the conductive film 52 are stacked as an example, see Figure 8 As shown, the conductive member 50 may further include an adhesive layer 53 , and the adhesive layer 53 may be located between the head end 52 a and the tail end 52 b , so that the head end 52 a and the tail end 52 b may be connected and fixed together through the adhesive layer 53 .

[0144] It can be understood that before the conductive film 52 is enclosed into the conductive part 50, glue can be applied to the head end 52a and / or the tail end 52b of the conductive film 52. When the conductive film 52 is enclosed into the conductive part 50, the head end 52a and the tail end 52b are stacked, and the head end 52a and the tail end 52b are bonded together by applying glue, and an adhesive layer 53 is formed between the head end 52a and the tail end 52b.

[0145] Of course, in some other examples, the head end 52a and the tail end 52b of the conductive film 52 can also be connected in other ways to form the conductive member 50. For example, the head end 52a and the tail end 52b can be connected by welding, fastening with fixing parts, snapping, etc.

[0146] To achieve the fixing and electrical connection of the conductive member 50 to the housing 10 and the flexible screen 20, see Figure 8 As shown, the conductive member 50 may further include a first conductive adhesive layer 54 and a second conductive adhesive layer 55. The first conductive adhesive layer 54 is located between the first end 50a of the conductive member 50 and the shell 10. For example, the first conductive adhesive layer 54 may be disposed on a surface of the first end 50a of the conductive member 50 that faces away from the cavity 51. The first end 50a of the conductive member 50 may be electrically connected to the shell 10 through the first conductive adhesive layer 54, thereby achieving fixation and electrical connection between the conductive member 50 and the shell 10.

[0147] The second conductive adhesive layer 55 may be located between the second end 50b of the conductive member 50 and the flexible screen 20. For example, the second conductive adhesive layer 55 may be disposed on a surface of the second end 50b of the conductive member 50 that faces away from the cavity 51. The second end 50b of the conductive member 50 may be electrically connected to the flexible screen 20 through the second conductive adhesive layer 55, thereby achieving fixation and electrical connection between the conductive member 50 and the flexible screen 20. The connection structure is simple, easy to implement, and low in cost.

[0148] In the embodiment of the present application, the conductive film 52 may be a thin layer structure having flexibility and conductivity. Exemplarily, the conductive film 52 may be a single layer structure. For example, the conductive film 52 may be a flexible thin layer structure formed by a conductive material having conductivity itself, such as the conductive film 52 may be a metal film, and exemplary, the conductive film 52 may be a metal foil, such as but not limited to copper foil, aluminum foil, etc.

[0149] Alternatively, the conductive film 52 may be a single-layer structure that has been modified to be conductive. For example, the conductive film 52 may be a conductive cloth. The molding material of the conductive cloth may include polyester and conductive fibers. For example, by carbonizing the conductive fibers or mixing carbon black and fiber materials, the carbon black forms a continuous structure on the fibers, which can give the fibers conductivity. The conductive cloth formed using polyester and conductive fibers as raw materials can be flexible and conductive.

[0150] That is, the conductive member 50 is formed by a thin layer structure such as a conductive metal film or conductive cloth. For example, the head end 52a and the tail end 52b of the metal film or conductive cloth are connected to form a conductive member 50 having a cavity 51 inside, which meets the expansion and contraction and conductivity requirements of the conductive member 50. The structural design is simple and easy to assemble, which is conducive to improving assembly efficiency and reducing production costs. In addition, the conductive film 52 includes conductive cloth, which is relatively low in cost and easy to produce.

[0151] Fig. 9 A schematic diagram of the cross-sectional structure of another conductive member provided in an embodiment of the present application.

[0152] In some examples, the conductive film 52 may also be a multi-layer structure. Exemplarily, the conductive film 52 may include a flexible film layer 521 and a conductive layer 522, wherein the conductive layer 522 is disposed on a side of the flexible film layer 521 facing away from the cavity 51, and the conductive layer 522 extends at least from the first end 50a to the second end 50b of the conductive member.

[0153] The flexible film layer 521 is flexible and can give the conductive film 52 flexibility to achieve the expansion and contraction of the conductive member 50. The conductive layer 522 is conductive and can give the conductive film 52 conductivity to meet the electrical connection between the first end 50a and the second end 50b of the conductive member 50 and the housing 10 and the flexible screen 20. Enriching the structural design of the conductive film 52 makes the conductive member 50 have better structural flexibility, which helps to expand the application range of the conductive member 50.

[0154] It should be noted that the conductive layer 522 may only cover a portion of the flexible film layer 521 that is sufficient to ensure electrical connection between the first end 50a and the second end 50b of the conductive member 50, which helps to reduce costs.

[0155] Alternatively, the conductive layer 522 is located on the side of the flexible film layer 521 facing away from the cavity 51, and the conductive layer 522 can also completely cover the side of the flexible film layer 521 facing away from the cavity 51, so that the thickness of the entire conductive film 52 remains consistent, which is more conducive to achieving the effect of no change in the touch feel when the touch operation passes through the conductive area.

[0156] The flexible film layer 521 may be a thin layer structure without conductivity. For example, the flexible film layer 521 may include but is not limited to flexible cloth, polyimide (PI) film, and the like.

[0157] The molding material of the conductive layer 522 may include a conductive material, for example, may include a metal material. For example, the conductive layer 522 may be a metal plating layer. The conductive layer 522 may include but is not limited to a gold plating layer, a nickel plating layer, a tin plating layer, and the like.

[0158] For example, the flexible film layer 521 may be a PI film, the conductive layer 522 may be a gold-plated layer, and the conductive film 52 may be a gold-plated PI film. Alternatively, the conductive layer 522 may be a nickel-plated layer, and the conductive film 52 may be a nickel-plated PI film. Alternatively, the conductive layer 522 may be a tin-plated layer, and the conductive film 52 may be a tin-plated PI film, and so on.

[0159] Of course, in some examples, the flexible film layer 521 may also be a thin layer structure having conductivity, for example, the flexible film layer 521 may also be a metal film, a conductive cloth, etc.

[0160] In some examples, the molding material of the conductive layer 522 may also include a material having adhesive properties. For example, the conductive layer 522 may be an adhesive layer including a conductive adhesive. The molding material of the conductive adhesive may include a resin and a conductive material. For example, the resin may include an epoxy resin, an acrylate resin, a polyvinyl chloride, etc., and the conductive material may include a metal material, such as silver particles, copper particles, etc.

[0161] Fig.10 A schematic diagram of the cross-sectional structure of another conductive member provided in an embodiment of the present application.

[0162] The conductive layer 522 may include conductive glue, which has conductivity and adhesiveness, and the conductive layer 522 may be directly bonded to the flexible film layer 521 to form the conductive film 52. When the head end 52a and the tail end 52b of the conductive film 52 are connected to form the conductive member 50, the conductive layer 522 (conductive glue) is located on the side of the flexible film layer 521 facing away from the cavity 51, and the head end 52a and the tail end 52b may be bonded together by part of the conductive glue (conductive layer 522), that is, part of the conductive glue may form an adhesive layer 53 located between the head end 52a and the tail end 52b.

[0163] The conductive glue (conductive layer 522) located at the first end 50a of the conductive member 50 can also be directly bonded and fixed to the shell 10 to achieve fixation and electrical connection between the first end 50a of the conductive member 50 and the shell 10, that is, part of the conductive glue can form a first conductive glue layer 54 between the conductive member 50 and the shell 10.

[0164] The conductive glue (conductive layer 522) located at the second end 50b of the conductive member 50 can also be directly bonded and fixed to the flexible screen 20 to achieve fixation and electrical connection between the second end 50b of the conductive member 50 and the flexible screen 20, that is, part of the conductive glue can form a second conductive glue layer 55 between the conductive member 50 and the flexible screen 20.

[0165] That is, when the conductive film 52 is used to form the conductive part 50, the conductive glue (conductive layer 522) included in the conductive film 52 itself can be used to bond the head end 52a and the tail end 52b of the conductive film 52, and the conductive glue can also be used to directly bond the conductive part 50 to the shell 10 and the flexible screen 20, without the need to set up an additional adhesive layer and a conductive glue layer. The molding and operation methods of the conductive part 50 are simple, the molding difficulty and cost are low, and it is easy to produce.

[0166] It can be understood that the conductive adhesive as the conductive layer 522 can form a conductive film 52 with the conductive flexible film layer 521. For example, the flexible film layer 521 can be a metal film, a conductive cloth, or the like.

[0167] Alternatively, the conductive film 52 may be formed with a non-conductive flexible film layer 521 . For example, the flexible film layer 521 may be a flexible cloth, a PI film, or the like.

[0168] Fig.11 A schematic cross-sectional structure diagram of another conductive element provided in an embodiment of the present application.

[0169] In some examples, the conductive film 52 located at the first end 50a of the conductive member 50 may have a first through hole (not shown in the figure), and the conductive film 52 located at the second end 50b of the conductive member 50 may have a second through hole (not shown in the figure).

[0170] For example, in the example where the conductive film 52 includes conductive cloth, the conductive cloth is woven from fibers, and the gaps between the fibers form through holes on the conductive cloth. After the head end 52a and the tail end 52b of the conductive cloth are connected to form the conductive member 50, the fiber gaps of the portion of the conductive cloth located at the first end 50a can form a first through hole, and the fiber gaps of the portion of the conductive cloth located at the second end 50b can form a second through hole.

[0171] It can be understood that the fiber gaps of the conductive cloth are mostly evenly distributed in an array. After the conductive cloth is used to form the conductive member 50, the fiber gaps can be evenly distributed on the entire conductive member 50. The fiber gaps located at the first end 50a can be the first through holes, and the fiber gaps located at the second end 50b can be the second through holes.

[0172] Of course, in some examples, only the conductive film 52 (conductive cloth) located at the first end 50 a may have the first through hole, and the conductive film 52 located at the second end 50 b may have the second through hole.

[0173] See also Fig.11 As shown, a first conductive adhesive layer 54 is provided on the side of the first end 50a of the conductive member 50 facing away from the cavity 51, and an adhesive layer 53 is also provided between the head end 52a and the tail end 52b forming the first end 50a. When the conductive member 50 is extremely compressed in scenes such as touch operation, the adhesive layer 53 and the first conductive adhesive layer 54 may overflow with adhesive under the action of pressing, such as overflowing through the first through hole to the side of the first end 50a of the conductive member 50 facing the cavity 51 (the second end 50b), so that the first end 50a of the conductive member 50 is easily bonded to the second end 50b through the overflowed adhesive. It is not convenient to reset the second end 50b of the conductive member 50 and the flexible screen 20 after the pressing is removed, resulting in defects such as partial depression of the flexible screen 20, affecting the flatness.

[0174] Correspondingly, a second conductive adhesive layer 55 is provided on the side of the second end 50b of the conductive member 50 facing away from the cavity 51. In a touch operation scenario, the second conductive adhesive layer 55 is easy to overflow through the second through hole to the side of the second end 50b of the conductive member 50 facing the cavity 51 (first end 50a) under the action of pressing, and the first end 50a and the second end 50b may be bonded together by the overflowed adhesive, affecting the flatness.

[0175] Therefore, in this example, if Fig.11As shown, the conductive member 50 may further include a first anti-seepage layer 56. The first anti-seepage layer 56 may be disposed on a side of the first end 50a facing the cavity 51. The first anti-seepage layer 56 and the first conductive adhesive layer 54 are located on two opposite sides of the first end 50a along the expansion and contraction direction. The first anti-seepage layer 56 may be disposed on a side of the partial conductive film 52 forming the first end 50a facing the cavity 51.

[0176] The first anti-seepage layer 56 covers the first through hole, which can prevent the first conductive glue layer 54 and the adhesive layer 53 from overflowing through the first through hole to the side of the first end 50a facing the cavity 51, thereby avoiding the adhesion problem between the first end 50a and the second end 50b when the conductive part 50 is extremely compressed, thereby improving the flatness of the flexible screen 20.

[0177] Correspondingly, the conductive member 50 may further include a second anti-seepage layer 57. The second anti-seepage layer 57 may be arranged on a surface of the second end 50b facing the cavity 51. The second anti-seepage layer 57 and the second conductive adhesive layer 55 are located on two opposite surfaces of the second end 50b along the expansion and contraction direction. The second anti-seepage layer 57 may be arranged on a surface of the partial conductive film 52 forming the second end 50b facing the cavity 51.

[0178] The second anti-seepage layer 57 covers the second through hole, which can prevent the second conductive adhesive layer 55 from overflowing through the second through hole to the side of the second end 50b facing the cavity 51, and can also prevent the adhesion problem between the first end 50a and the second end 50b when the conductive member 50 is extremely compressed.

[0179] It can be understood that in the example where the conductive part 50 is surrounded by a conductive film 52 without through holes, for example, the conductive part 50 is formed by a metal film without through holes or a PI film without through holes, the above-mentioned first waterproof layer 56 and the second waterproof layer 57 may not be provided. Omitting the provision of the waterproof layer is conducive to simplifying the molding steps and reducing production costs.

[0180] For example, taking the conductive film 52 as a single-layer conductive cloth as an example, in actual assembly, the conductive cloth can be first cut into a strip structure with a certain width, and a first anti-seepage layer 56 and a second anti-seepage layer 57 are arranged at corresponding positions of the conductive cloth, and glue is applied on at least one side of the head end 52a and the tail end 52b of the conductive cloth. Then, the conductive cloth is folded to enclose a conductive member 50 having a cavity 51 inside, and the head end 52a and the tail end 52b are bonded together by an adhesive layer 53 formed by glue application, so that the first end 50a of the conductive member 50 facing the cavity 51 has the first anti-seepage layer 56, and the second end 50b of the conductive member 50 facing the cavity 51 has the second anti-seepage layer 57. Finally, a first conductive adhesive layer 54 is formed on the surface of the first end 50a of the conductive member 50 facing away from the cavity 51, and the conductive member 50 is fixed to the shell through the first conductive adhesive layer 54. A second conductive adhesive layer 55 is formed on the surface of the second end 50b of the conductive member 50 facing away from the cavity 51, and the flexible screen is bonded to the second conductive adhesive layer 55. The flexible screen is pressed, and the conductive member 50 is pressed by the flexible screen to make the flexible screen, the second conductive adhesive layer 55, the conductive member 50, and the conductive member 50, the first conductive adhesive layer 54, and the shell fully squeezed and bonded, thereby realizing the assembly of the conductive member 50, the shell and the flexible screen.

[0181] Of course, in some other examples, the conductive member may also be other types of conductive structures that can shrink and have a cavity between the two ends in the expansion and contraction direction. For example, the conductive member may include two rigid conductive sheets and a flexible conductive film. The two conductive sheets may be located on both sides of the conductive film. The two conductive sheets are spaced apart and electrically connected through the conductive film. The two conductive sheets respectively form the first end and the second end of the conductive member. The interval between the two conductive sheets forms a cavity, one of which may be electrically connected to the flexible screen, and the other conductive sheet may be electrically connected to the shell. The flexible conductive film can enable the two conductive sheets to move relative to each other to realize the expansion and contraction of the conductive member. The conductive member expands and contracts and compresses the cavity between the conductive sheets. Under the condition of ensuring reliable electrical connection between the flexible screen and the shell, it can also avoid problems such as marks on the flexible screen and variations in feel during touch operation.
