Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of terminal devices, and in particular to a foldable electronic device. Background Art

[0002] A foldable electronic device with a flexible screen provides a large display area when unfolded, while maintaining a compact, easily stowable structure when folded. The foldable electronic device includes a hinge mechanism and housings disposed on either side of the hinge mechanism. The two housings can rotate relative to the hinge mechanism to unfold and fold the housings relative to each other. Printed circuit boards and other components are housed within the two housings. These components are electrically connected via a through-the-shaft flexible circuit board (FPCB). The FPCB passes through the hinge mechanism, with its ends inserted into the two housings and connected to the corresponding components.

[0003] After the flexible circuit board is threaded through the hinge mechanism, fasteners are needed to secure the two ends of the flexible circuit board to prevent it from coming loose. In the related art, screw holes are typically added to the housing on both sides of the hinge mechanism in the areas where the motherboard and / or battery are mounted, allowing the fasteners to be screwed into the holes.

[0004] With the development of technology, people are increasingly demanding more efficient use of space in the entire computer. However, adding screw holes to the area where the motherboard and / or battery are installed will significantly occupy the installation space of the motherboard and / or battery, resulting in a reduction in the application area of the motherboard and / or battery. Summary of the Invention

[0005] An embodiment of the present application provides a foldable electronic device, which can solve the problem of excess space occupation in the housing on both sides of the rotating shaft mechanism when fixing the flexible circuit board through the shaft in the related art.

[0006] An embodiment of the present application provides a foldable electronic device, comprising: a first main body, a second main body, a hinge mechanism, a through-axis flexible circuit board, and a pressing member, wherein the first main body and the second main body are respectively connected to both sides of the hinge mechanism, and the first main body and the second main body are relatively unfolded and folded through the hinge mechanism, the middle portion of the through-axis flexible circuit board spans the hinge mechanism, the first end of the through-axis flexible circuit board extends into the first main body, and the second end of the through-axis flexible circuit board extends into the second main body, and pressing members are provided on both sides of the hinge mechanism, mounting holes are opened on both sides of the hinge mechanism, and mounting portions are provided on the pressing member corresponding to the mounting holes, and the mounting portions are locked to the mounting holes so that the two ends of the through-axis flexible circuit board are respectively pressed against the two sides of the hinge mechanism, and the through-axis flexible circuit board is pressed between the pressing member and the hinge mechanism.

[0007] The foldable electronic device provided in the embodiment of the present application has mounting holes on both sides of the hinge mechanism, and the ends of the through-axis flexible circuit board are pressed against the two sides of the hinge mechanism by locking the pressing members in the mounting holes. On the one hand, the through-axis flexible circuit board can be fixed. On the other hand, it can avoid adding screw holes in the first and second main bodies to affect the installation area and application area of the internal components of the body, improve the utilization rate of the internal space of the body, and help improve the high precision of the whole machine. It can also avoid opening screw holes in the non-hollowed-out areas of the first and second main bodies to affect the overall strength of the first and second main bodies. On the other hand, the mounting holes can also be the connection holes between the first and second main bodies and the hinge mechanism. It can be understood that the connection holes and mounting holes of the first and second main bodies and the hinge mechanism are shared by each other, which is conducive to improving the high precision of the foldable electronic device.

[0008] In a possible embodiment, the first main body and the second main body are connected to the hinge mechanism via the mounting hole, thereby improving the high precision of the foldable electronic device.

[0009] In a possible embodiment, the pressing member is strip-shaped and is arranged parallel to the extension direction of the rotating shaft mechanism. Both ends of the pressing member have the mounting portion, and the through-axis flexible circuit board is pressed between the mounting portions at both ends of the pressing member.

[0010] This facilitates assembly of the clamping element, allowing the through-shaft flexible circuit board to be secured by simply pressing and tightening it. Furthermore, when the mounting holes serve as connection holes between the first and second main bodies, this also facilitates assembly and connection between the first and second main bodies and the hinge mechanism.

[0011] In a possible embodiment, the foldable electronic device further includes: a first seal and a second seal, wherein the first seal is arranged between the rotating shaft mechanism and the through-axis flexible circuit board, and the second seal is arranged between the pressing member and the through-axis flexible circuit board.

[0012] In this way, it is possible to prevent external dust, water stains, etc. from entering the interior of the rotating shaft mechanism through the gap between the pressing member and the rotating shaft mechanism and causing damage to the flexible circuit board passing through the shaft.

[0013] In a possible implementation manner, the first sealing member is adhesive, and the adhesive is adhered to a surface of the through-shaft flexible circuit board facing away from the pressing member and is also adhered to the rotating shaft mechanism.

[0014] Thus, when placing the through-axis flexible circuit board, the adhesive can play a role in pre-fixing and pre-positioning the through-axis flexible circuit board. Moreover, after the pressing member is pressed against the through-axis flexible circuit board, the adhesive can further strengthen the fixation of the through-axis flexible circuit board.

[0015] In a possible implementation, the second sealing member is foam, which is adhered to a surface of the pressing member facing the through-shaft flexible circuit board, and has an interference fit with the through-shaft flexible circuit board.

[0016] Thus, after the flexible circuit board is placed, the interference fit between the foam and the flexible circuit board can enhance the waterproof and dustproof performance between the pressing member and the rotating shaft mechanism. In addition, the foam as a sealing member is non-sticky, which can facilitate the removal of the pressing member.

[0017] In a possible implementation, the mounting portion has a buckle, which is engaged in the mounting hole to facilitate disassembly of the clamping member.

[0018] In a possible embodiment, the rotating shaft mechanism includes: a bracket, a swing arm and a connecting component, wherein connecting components are respectively provided on both sides of the bracket, and the connecting components are connected to the bracket through the swing arm. The connecting components located on both sides of the bracket are respectively connected to the first main body and the second main body, and the mounting hole is opened on the connecting component.

[0019] The connecting components of the hinge mechanism (door panels, wedge blocks, etc.) have extra space to open mounting holes, which can improve the utilization rate of the internal structure of the body and is conducive to improving the high precision of foldable electronic devices.

[0020] In a possible implementation, the foldable electronic device further includes: a flexible screen, wherein the flexible screen is attached to a surface of the first main body portion and the second main body portion that is away from each other or close to each other.

[0021] In a possible implementation, the foldable electronic device is a foldable mobile phone. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] 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. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0044] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a" does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0045] The embodiment of the present application provides a foldable electronic device, wherein the foldable electronic device can be a terminal product such as a mobile phone, a tablet computer (pad), a television, a smart wearable product (for example, a smart watch, a smart bracelet, etc.), a virtual reality (VR) device, an augmented reality (AR) device, or a professional shooting device such as a digital camera, a single-lens reflex camera, a micro single-lens camera, a sports camera, etc. The embodiment of the present application does not limit the specific type of the foldable electronic device, as long as it is an electronic device with a hinge mechanism. For ease of understanding, the embodiment of the present application takes the foldable electronic device as an example of a foldable mobile phone.

[0046] Figure 1 This is a schematic diagram of the folded structure of the foldable electronic device 100 provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the unfolded structure of the foldable electronic device 100 provided in one embodiment of the present application, with reference to Figure 1 and Figure 2 As shown, the foldable electronic device 100 provided in the embodiment of the present application includes: a flexible screen 110, a first main body 120, a second main body 130 and a hinge mechanism 140. The embodiment of the present application is described with two main bodies.

[0047] Specifically, the first main body 120 and the second main body 130 are respectively connected to the two sides of the hinge mechanism 140. The hinge mechanism 140 enables the first main body 120 and the second main body 130 to be relatively unfolded and folded. For a mobile phone, the first main body 120 and the second main body 130 can be the middle frame. It is understandable that the specific structure of the first main body 120 and the second main body 130 can be determined according to the specific electronic device. This application does not limit the specific structure of the first main body 120 and the second main body 130, and is not limited to the above-mentioned example of the first main body 120 and the second main body 130 being the middle frame. In addition, the structures of the first main body 120 and the second main body 130 can be the same, not completely the same, or completely different.

[0048] It can be understood that in other embodiments of the present application, in addition to using one hinge mechanism 140 and two main bodies to form a two-layer folding structure, the foldable electronic device 100 can also use multiple hinge mechanisms 140 and more than two main bodies to form a multi-layer folding structure.

[0049] For the sake of convenience, refer to Figure 2 As shown in , a spatial coordinate system is established. When the foldable electronic device 100 is in a flattened state, the extension direction of the hinge mechanism 140 is defined as the first direction X. The second direction Y is perpendicular to the first direction X, and both the first direction X and the second direction Y are parallel to the plane containing the first and second main body portions 120 and 130. The third direction Z is perpendicular to the plane containing the first and second directions X and Y. This coordinate system is used in the description of the foldable electronic device 100 below and in the accompanying drawings.

[0050] The flexible screen 110 is attached to the side of the first main body 120 and the second main body 130 that are closer to or farther away from each other when they are folded. Figure 2 As shown in the figure, from the user's perspective, when the foldable electronic device 100 is in a flattened state, the user faces the flexible screen 110, and the flexible screen 110 is attached to the upper surfaces of the first and second main bodies 120, 130. During the relative unfolding and folding of the first and second main bodies 120, 130, the flexible screen 110 is also unfolded and folded simultaneously with the first and second main bodies 120, 130.

[0051] like Figure 1 As shown in , the foldable electronic device 100 can be folded into a folded state; Figure 2 As shown in , the foldable electronic device 100 can be unfolded to a flattened state. Of course, the foldable electronic device 100 can also be unfolded or folded to an intermediate state, which can be any state between the flattened state and the folded state. The flexible screen 110 is a bendable structure that moves with the first body portion 120 and the second body portion 130. The first body portion 120 and the second body portion 130 can drive the flexible screen 110 to flatten or fold, so that the foldable electronic device 100 can be unfolded or folded to a flattened state, a folded state, or an intermediate state. In some embodiments of the present application, when the foldable electronic device 100 is in the folded state, the flexible screen 110 is located inside the first body portion 120 and the second body portion 130, and the foldable electronic device 100 is an inward-folding screen device. In some embodiments of the present application, when the foldable electronic device 100 is in the folded state, the flexible screen 110 is located outside the first body portion 120 and the second body portion 130, and the foldable electronic device 100 is an outward-folding screen device.

[0052] In the embodiment of the present application, when the foldable electronic device 100 is in a flattened state, the flexible screen 110 can display a full-screen image, so that the foldable electronic device 100 has a larger display area, thereby improving the user's viewing and operating experience. When the foldable electronic device 100 is in a folded state, the foldable electronic device 100 has a small planar size, making it easy for the user to carry and store.

[0053] It should be noted that when the foldable electronic device 100 is in a flattened state, the angle between the first main body 120 and the second main body 130 may deviate slightly from 180°, such as 165°, 178°, or 185°. In this case, the first and second main body 120, 130 are also considered to be in a flattened state. The angle between the first and second main body 120, 130 is defined as the angle between the upper sides of the first and second main body 120, 130. For example, the foldable electronic device 100 can be considered to be in a flattened state when the angle between the first and second main body 120, 130 is any value between 165° and 190°.

[0054] like Figure 1 As shown, when the foldable electronic device 100 is in a folded state, the two sides of the foldable electronic device 100 are close to each other, the angle between the first main body 120 and the second main body 130 can be approximately 0°, the first main body 120 and the second main body 130 are folded to a closed state, and the flexible screen 110 is in a folded state. For example, when the first main body 120 and the second main body 130 are in a closed state, the two can contact each other to achieve positioning. In some other embodiments, when the first main body 120 and the second main body 130 are in a closed state, the two can also be close to each other, and there is a small gap between them. This application does not strictly limit this.

[0055] When there is a tiny gap between the first main body 120 and the second main body 130, some foreign objects outside the foldable electronic device 100 (such as stators, stones, glass shards, etc.) will not enter between the first main body 120 and the second main body 130 through the gap, so as to avoid foreign objects damaging the flexible screen 110 and improve the reliability of the foldable electronic device 100.

[0056] It is understood that the first body portion 120 and the second body portion 130 are the housing components of the foldable electronic device 100, used to mount and secure other components of the foldable electronic device 100, and have a variety of structures. For example, in some embodiments of the present application, the foldable electronic device 100 may further include multiple components (not shown in the figure), which may be mounted inside the first body portion 120 and the second body portion 130. The multiple components may include, for example, a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, a button, a motor, an indicator, and a subscriber identification module (SIM) card interface. The foldable electronic device 100 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. Each component may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits. The embodiment of the present application does not impose strict restrictions on the specific structures of the first main body 120 and the second main body 130 .

[0057] It is understandable that the first main body portion 120 and the second main body portion 130 can be continuous, complete surfaces, or can be surfaces including multiple recessed areas or hollow areas, and the embodiments of the present application do not limit this.

[0058] Continue to refer Figure 1 As shown, in some embodiments of the present application, the foldable electronic device 100 may further include: a shaft cover 150, which is arranged on the side of the hinge mechanism 140 facing away from the flexible screen 110, and can serve to shield the hinge mechanism 140. On the one hand, it can improve the aesthetics of the appearance of the foldable electronic device 100, and on the other hand, it can protect the hinge mechanism 140 to prevent the hinge mechanism 140 from being damaged by external forces.

[0059] The shaft mechanism 140 can be configured according to specific needs. Figure 1 and Figure 2 It is only used to illustrate the position of the hinge mechanism 140. In this application, there is no limitation on the specific structure of the hinge mechanism 140, as long as it can realize the opening and closing of the foldable electronic device 100.

[0060] In an embodiment of the present application, the flexible screen 110 may include a display component and a transparent cover. The display component can display images and videos, etc. The display component can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light-emitting diode (QLED), etc. The transparent cover and the display component are stacked in a third direction Z, and the transparent cover is arranged on the outside of the display component. It can be understood that the transparent cover is provided on the side of the display component facing away from the first main body 120 and the second main body 130 to protect the display component. The transparent cover can be a glass cover, or of course, other transparent materials that can perform a protective function. The flexible screen 110 can also have a touch function, that is, the flexible screen 110 can be a touch screen.

[0061] Figure 3 The structure of the first main body 120, the second main body 130, the rotating shaft mechanism 140 and the through-shaft flexible circuit board 160 provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, in the embodiment of the present application, the foldable electronic device 100 further includes: a through-axis flexible circuit board 160.

[0062] Specifically, the first and second body sections 120 and 130 of the foldable electronic device 100 may contain various components, such as printed circuit boards, processors, memory, and cameras. These components may be installed in the first and second body sections 120 and 130, respectively. For example, components such as the first printed circuit board, battery, processor, and memory may be located in the first body section 120, while components such as the second printed circuit board and camera assembly may be located in the second body section 130. To electrically connect the components in the different body sections, a through-axis flexible circuit board 160 may be positioned on the hinge mechanism 140. The middle portion of the through-axis flexible circuit board 160 spans the hinge mechanism 140, with the first end of the through-axis flexible circuit board 160 extending into the first body section 120 and the second end of the through-axis flexible circuit board 160 extending into the second body section 130. The two ends of the through-axis flexible circuit board 160 are connected to the components in the different body sections, thereby achieving electrical connection between the components in the different body sections.

[0063] After the through-axis flexible circuit board 160 is assembled on the hinge mechanism 140, it is necessary to use a fixing member to fix the through-axis flexible circuit board 160 to prevent the through-axis flexible circuit board 160 from loosening during use of the foldable electronic device 100. In the related art, fixing members are generally provided in the first main body 120 and the second main body 130 on both sides of the hinge mechanism 140 to fix the two ends of the through-axis flexible circuit board 160. For example, Figure 3 The space in the middle A is the battery compartment, and the space in the B is the circuit board compartment. In the related art, screw holes are added at the A and B positions, and fixing parts are locked in the screw holes to fix the through-axis flexible circuit board 160.

[0064] However, since Parts A and B were originally hollowed-out areas, adding screw holes would occupy the original battery and circuit board space, reducing the usable area of the battery and circuit board. Of course, the reference to Part A as the battery compartment and Part B as the circuit board is merely an example; Parts A and B could also be mounting locations for other components. Adding screw holes would also reduce the mounting area or the usable area of other components, compromising the high precision of the entire device.

[0065] To address the aforementioned issues, an embodiment of the present application provides a foldable electronic device 100. Mounting holes 141 are defined on either side of the hinge mechanism 140. A clamping member 170 is locked into the mounting holes 141, pressing the ends of a flexible printed circuit board 160 against the hinge mechanism 140. This secures the flexible printed circuit board 160. Furthermore, it prevents the addition of screw holes within the first and second body portions 120 and 130 from impacting the mounting and application area of internal components, thereby improving the overall precision of the device. Furthermore, it prevents the addition of screw holes within the non-hollowed-out areas of the first and second body portions 120 and 130, which would otherwise affect their overall strength. Furthermore, the mounting holes 141 can also serve as connecting holes between the first and second body portions 120 and 130 and the hinge mechanism 140. This means that the connecting holes between the first and second body portions 120 and 130 and the hinge mechanism 140 and the mounting holes 141 are shared, further enhancing the precision of the foldable electronic device 100.

[0066] The foldable electronic device 100 provided in the embodiment of the present application will be further described below with reference to the accompanying drawings and specific embodiments.

[0067] Figure 4 The structure of the first main body 120, the second main body 130, the rotating shaft mechanism 140 and the through-shaft flexible circuit board 160 provided in an embodiment of the present application is shown in FIG. Figure 4 Combined with Figure 3 As shown, Figure 4Can be regarded as Figure 3 The back view of the structure shown, i.e. Figure 3 What is shown are the first surfaces of the first main body 120 and the second main body 130 , and the first surfaces are the bonding surfaces of the flexible screen 110 . Figure 4 Shown is Figure 3 The first main body portion 120 and the second main body portion 130 have a second surface opposite to the first surface.

[0068] Among them, the foldable electronic device 100 also includes a clamping member 170, which is provided on both sides of the hinge mechanism 140. Mounting holes 141 are opened on both sides of the hinge mechanism 140, and mounting portions 171 are provided on the clamping member 170 corresponding to the mounting holes 141. The mounting portions 171 are locked to the mounting holes 141 so that the two ends of the through-axis flexible circuit board 160 are respectively pressed on the two sides of the hinge mechanism 140, and the through-axis flexible circuit board 160 is pressed between the clamping member 170 and the hinge mechanism 140.

[0069] For example, Figure 4 As shown in , the foldable electronic device 100 may include two pressing members 170. Two mounting holes 141 are respectively provided on both sides of the hinge mechanism 140. Each pressing member 170 corresponds to the two mounting holes 141 and presses the through-axis flexible circuit board 160 onto the hinge mechanism 140. The through-axis flexible circuit board 160 is pressed between the pressing member 170 and the hinge mechanism 140, and the two ends of the through-axis flexible circuit board 160 can be fixed. In this way, the through-axis flexible circuit board 160 is fixed as a whole to prevent the foldable electronic device 100 from loosening during use. The present application does not impose any restrictions on the structure and number of the pressing members 170 and the mounting holes 141. It is only necessary to ensure that the two ends of the through-axis flexible circuit board 160 are pressed against the two sides of the hinge mechanism 140.

[0070] It is easy to understand that the foldable electronic device 100 provided in the embodiment of the present application has mounting holes 141 on both sides of the hinge mechanism 140. The clamping members 170 are locked in the mounting holes 141, pressing the ends of the through-shaft flexible circuit board 160 against the two sides of the hinge mechanism 140. On the one hand, the through-shaft flexible circuit board 160 can be fixed. On the other hand, it can avoid adding screw holes in the first and second main bodies 120, 130 to affect the installation area and application area of internal components, improve the utilization rate of the internal space of the body, and help improve the high precision of the entire device. It can also avoid adding screw holes in the non-hollowed-out areas of the first and second main bodies 120, 130 to affect the overall strength of the first and second main bodies 120, 130. On the other hand, the mounting hole 141 can also be a connecting hole between the first main body 120 and the second main body 130 and the hinge mechanism 140. It can be understood that the connecting hole and the mounting hole 141 between the first main body 120 and the second main body 130 and the hinge mechanism 140 are shared, which is beneficial to improving the high precision of the foldable electronic device 100.

[0071] It should be mentioned that the cooperation between the pressing member 170 and the mounting hole 141 is not limited to Figure 4 In the embodiment shown in FIG, a screw fastening method is used. In some embodiments of the present application, a buckle can be provided on the mounting portion 171, and the buckle is engaged in the mounting hole 141 to facilitate the removal of the pressing member 170. Of course, the present application does not exclude the possibility of modifying the mounting hole 141 into a protruding buckle and providing a buckle hole on the mounting portion 171 to achieve the connection between the pressing member 170 and the rotating shaft mechanism 140.

[0072] In some embodiments of the present application, the first body portion 120 and the second body portion 130 can be connected to the hinge mechanism 140 through the mounting hole 141. For example, fasteners (such as screws) are used to lock the first body portion 120 and the second body portion 130 in the mounting hole 141. That is, the first body portion 120 and the second body portion 130 share the connection hole and the mounting hole 141 with the hinge mechanism 140, which is conducive to improving the high precision of the foldable electronic device 100.

[0073] In some embodiments of the present application, the pivot mechanism 140 may include: a bracket, a swing arm and a connecting component, wherein connecting components are respectively provided on both sides of the bracket, and the connecting components are connected to the bracket through the swing arm. The connecting components located on both sides of the bracket are respectively connected to the first main body 120 and the second main body 130, and the mounting hole 141 is opened on the connecting component.

[0074] The structure of the hinge mechanism 140 and the connection between the hinge mechanism 140 and the first and second main bodies 120 and 130 can be referenced to the prior art and will not be further elaborated herein. The connecting components of the hinge mechanism 140 (door panel, wedge block, etc.) have extra space for the mounting hole 141, which improves the utilization of the internal structure and facilitates the high precision of the foldable electronic device 100.

[0075] Of course, this application does not stop here, please continue to refer to Figure 4 As shown, in some embodiments of the present application, the pressing member 170 is strip-shaped and arranged parallel to the extension direction of the rotating shaft mechanism 140. Both ends of the pressing member 170 have mounting portions 171, and the through-shaft flexible circuit board 160 is compressed between the mounting portions 171 at both ends of the pressing member 170. This facilitates assembly of the pressing member 170, and the through-shaft flexible circuit board 160 can be secured by simply pressing and tightening the through-shaft flexible circuit board 160. Furthermore, when the mounting holes 141 are used as connection holes between the first and second body portions 120, 130, this also facilitates the connection and assembly between the first and second body portions 120, 130 and the rotating shaft mechanism 140.

[0076] Figure 5 for Figure 4 The cross-sectional view along the cutting line CC, Figure 6 for Figure 5 The enlarged structural diagram of the middle D part is shown in the figure. Figure 5 and Figure 6 As shown, in the foldable electronic device 100 provided in an embodiment of the present application, a certain redundant length is provided for the through-axis flexible circuit board 160 between the first body portion 120 and the second body portion 130 to meet the deformation requirements of the through-axis flexible circuit board 160 during the relative folding or unfolding of the first body portion 120 and the second body portion 130. In some embodiments of the present application, the redundant length of the through-axis flexible circuit board 160 can be set in the hinge mechanism 140. The space in the hinge mechanism 140 can accommodate a longer through-axis flexible circuit board 160, thereby preventing excessive deformation of the through-axis flexible circuit board 160 during the opening and closing of the first body portion 120 and the second body portion 130.

[0077] The two ends of the through-axis flexible circuit board 160 may include BTB (board to board) connectors 180, which are used to connect to the target electronic device. In other embodiments, the two ends of the through-axis flexible circuit board 160 may also be connected to the target device using a mechanism such as a gold finger.

[0078] Continue to refer Figure 5 and Figure 6As shown, in some embodiments of the present application, the foldable electronic device 100 may further include: a first seal 191 and a second seal 192, the first seal 191 being arranged between the hinge mechanism 140 and the through-axis flexible circuit board 160, and the second seal 192 being arranged between the clamping member 170 and the through-axis flexible circuit board 160, which can prevent external dust and water stains from entering the interior of the hinge mechanism 140 through the gap between the clamping member 170 and the hinge mechanism 140 and causing damage to the through-axis flexible circuit board 160.

[0079] It should be noted that the first seal 191 and the second seal 192 can be made of the same material or different materials. The first seal 191 and the second seal 192 can be a single piece or separate pieces. When the first seal 191 and the second seal 192 are a single piece, the first seal 191 and the second seal 192 are connected to form an annular shape. The annular seal is sleeved on the through-shaft flexible circuit board 160, and the through-shaft flexible circuit board 160 is then compressed by the compression member 170.

[0080] In some embodiments of the present application, the first sealing member 191 may be adhesive, which is bonded to the side of the through-shaft flexible circuit board 160 facing away from the pressing member 170 and to the rotating shaft mechanism 140. In this way, when the through-shaft flexible circuit board 160 is placed, the adhesive can pre-secure and pre-position the through-shaft flexible circuit board 160. Furthermore, after the pressing member 170 is pressed against the through-shaft flexible circuit board 160, the adhesive can further secure the through-shaft flexible circuit board 160.

[0081] In some embodiments of the present application, the second sealing member 192 may be a foam member adhered to the side of the compression member 170 facing the through-shaft flexible circuit board 160, creating an interference fit between the foam member and the through-shaft flexible circuit board 160. This interference fit enhances the waterproof and dustproof properties between the compression member 170 and the rotating shaft mechanism 140 after the through-shaft flexible circuit board 160 is positioned. Furthermore, the foam member, as a sealing member, is non-sticky, facilitating removal of the compression member 170.
