An electronic device
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on July 11, 2023, with application number 202310851318.X and invention name “An Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art
[0003] Electronic devices such as mobile phones, tablets, and laptops require electrical connectivity between components, such as between the hinge mechanism and the midframe, and between the camera module and the midframe. While these components must maintain electrical connectivity, they must also avoid corrosion in the conductive areas to minimize impedance and passive intermodulation (PIM). However, existing technologies often fail to meet this requirement.
[0004] Summary of the Invention
[0005] The present application provides an electronic device capable of preventing corrosion from occurring at electrically conductive portions between components.
[0006] To achieve the above objectives, the present application provides an electronic device comprising a first component, a second component, a conductive member, and a sealing ring. The conductive member is disposed between the first and second components and is electrically conductive with the first and second components. The sealing ring is disposed between the first and second components, with one axial end of the sealing ring facing the first component and the other end facing the second component. The conductive member is located within the area surrounded by the sealing ring.
[0007] In this way, electrical conduction between the first component and the second component can be achieved with the help of the conductive part. At the same time, the electrical conduction part between the first component and the second component can be sealed with the help of the sealing ring to prevent moisture from entering, avoid corrosion, and ensure the reliability of the electrical connection. The first component or the second component can be selected from chemically active metals such as magnesium alloys, which increases the material selection range of the first component and the second component, which is conducive to reducing the weight of the electronic equipment.
[0008] The conductive parts include but are not limited to conductive bosses, conductive gaskets, conductive springs and conductive springs.
[0009] In a possible implementation, the conductive member is a conductive spring. The conductive spring is relatively small and is easy to install between the first component and the second component in a limited space.
[0010] In one possible implementation, the conductive spring includes a fixing portion, an elastic arm portion, and a contact portion. The fixing portion is fixed to and electrically conductive with the first component, and the contact portion is in contact with and electrically conductive with the second component. The surface of the first component facing the second component is the first surface. The elastic arm portion includes a first end portion and a second end portion that are opposite to each other, and the direction from the first end portion to the second end portion is inclined relative to the first surface. The first end portion is connected to and electrically conductive with the fixing portion, and the second end portion is connected to and electrically conductive with the contact portion. In this way, during the installation of the conductive spring between the first component and the second component, the elastic arm portion can bend toward the first component, thereby accumulating an elastic force. This elastic force can cause the contact portion to stably abut against the second component, thereby ensuring the contact reliability between the contact portion and the second component. At the same time, the conductive spring can also adapt to installation between different gaps. The conductive spring is relatively thin and can be installed in a gap with limited height, without affecting the thickness of the electronic device, which is conducive to achieving thinness of the electronic device.
[0011] In one possible implementation, the fixing portion includes a third end and a fourth end relative to each other, and the direction from the third end to the fourth end is a first direction. The first direction is parallel to the first surface. The first end is connected to the fourth end and is electrically conductive. The orthographic projection of the first end on the first surface is a first projection, the orthographic projection of the second end on the first surface is a second projection, the direction from the first projection to the second projection is a second direction, and the second direction is opposite to the first direction. In this way, along the path of the third end → the fourth end → the first end → the second end, the conductive spring is bent in the opposite direction at least once, thereby reducing the size of the conductive spring in the first direction, avoiding the size of the first component and the second component being designed to be too large in the first direction, and thus helping to reduce the size of the electronic device.
[0012] In one possible implementation, the fixing portion and the elastic arm portion are spaced apart along a third direction, wherein the third direction is parallel to the first surface and perpendicular to the first direction. This ensures that the orthographic projection of the fixing portion on the first surface does not overlap with the orthographic projection of the elastic arm portion on the first surface, thereby avoiding any overlap in thickness between the fixing portion and the elastic arm portion. This helps reduce the height of the conductive spring, thereby reducing the stacked thickness of the first component, the conductive spring, and the second component, and facilitates a thinner design for the electronic device.
[0013] In one possible implementation, the conductive spring further includes a connecting portion. The connecting portion is located between the fourth end and the first end, and is connected to and electrically conductive with both the fourth end and the first end. The connecting portion extends along a third direction from the fourth end to the first end. This arrangement aligns the fourth end with the first end in the third direction, further reducing the size of the conductive spring in the first direction.
[0014] In one possible implementation, the orthographic projection of the elastic arm portion on the first surface is a third projection, and the length of the third projection in the first direction is less than the length of the fixed portion in the first direction. Thus, because the contact portion is connected to the second end, and therefore the fourth end and the first end are aligned in the third direction, the contact portion is located in the middle of the conductive spring in the first direction, and the area on the second surface surrounded by the sealing ring is defined as the first area. This allows the contact portion to contact the middle of the first area in the first direction, further ensuring the reliability of the electrical connection.
[0015] In a possible implementation, the edge of the second end away from the first end is the first edge, and the portion of the second end where the first edge is located forms the contact portion. In this way, the conductive spring has a simple structure and is easy to manufacture.
[0016] In one possible implementation, the edge of the second end facing the fixing portion is the second edge, which is a flange protruding toward the fixing portion. The edge of the second end away from the fixing portion is the third edge, and a circular arc transition edge or an inclined transition edge is connected to the first edge.
[0017] When a circular transition edge is connected between the third edge and the first edge, the circular transition edge protrudes in a direction away from the fixing portion and is tangent to both the first edge and the third edge. When an inclined transition edge is connected between the third edge and the first edge, one end of the inclined transition edge is connected to the third edge, and the other end extends in a direction away from the first end and is inclined toward the fixing portion, and the other end is connected to the first edge.
[0018] In this way, in the third direction, the contact portion is closer to the fixed portion, that is, the contact portion is located in the middle position of the conductive spring in the third direction, so that the contact portion can contact the middle position of the above-mentioned first area in the third direction, which is conducive to ensuring the stability and reliability of the electrical connection.
[0019] In one possible implementation, a first relief notch is provided on the edge of the fixed portion facing the elastic arm portion. When the elastic arm portion bends toward the first component to become coplanar with the fixed portion, the first relief notch is opposite the second edge along the third direction. In this way, the first relief notch can provide relief for a portion of the second end portion at the second edge, preventing the elastic arm portion from overlapping with the fixed portion in thickness when bent to become coplanar with the fixed portion, thereby further reducing the thickness of the conductive spring. Furthermore, the first relief notch can provide relief for the elastic arm portion, reducing the distance between the elastic arm portion and the fixed portion in the third direction and thereby reducing the size of the conductive spring in the third direction.
[0020] In one possible implementation, the elastic arm portion further includes an intermediate section connected between the first end and the second end. The edge of the intermediate section facing the fixed portion is a fourth edge, and the edge of the connecting portion facing the gap between the intermediate section and the fixed portion is a fifth edge. The fourth edge is connected to the fifth edge and is inclined toward the fixed portion along the direction from the second end to the first end. In this way, the width of the junction between the first end and the intermediate section is larger, the structural strength of the elastic arm portion is higher, and the elastic force is greater, enabling the contact portion to reliably contact the second component.
[0021] In one possible implementation, a second escape notch is provided on the edge of the fixed portion facing the elastic arm portion. When the elastic arm portion bends toward the first component to be coplanar with the fixed portion, the second escape notch is opposite the fourth edge along the third direction. In this way, the second escape notch can be used to avoid a portion of the middle section at the fourth edge, preventing the elastic arm portion from overlapping with the fixed portion when bent to be coplanar with the fixed portion, which is conducive to further reducing the thickness of the conductive spring. At the same time, the second escape notch can be used to avoid a portion of the middle section at the fourth edge, which can reduce the distance between the elastic arm portion and the fixed portion in the third direction, thereby reducing the size of the conductive spring in the third direction.
[0022] In one possible implementation, the contact portion includes a contact portion body and a first contact layer. The second end portion is connected to the contact portion body and electrically conductive therewith. The first contact layer is disposed on a surface of the contact portion body, and the conductivity of the first contact layer is greater than that of the contact portion body. The first contact layer contacts the second component. In this manner, the first contact layer can improve the electrical conductivity between the contact portion body and the second component, reducing impedance and passive intermodulation characteristics.
[0023] In a possible implementation, the material of the first contact layer includes at least one of gold, nickel, silver, and copper.
[0024] In one possible implementation, the surface of the first component facing the second component is the first surface, and the surface of the second component facing the first component is the second surface. The sealing ring is disposed between the first and second surfaces. This does not affect the structural strength of the first and second components.
[0025] In one possible implementation, a first recess is provided on the first surface, and at least the fixed portion of the conductive spring is accommodated in the first recess. This allows the height of the conductive spring to be increased, while maintaining a constant gap height between the first and second components, thereby enhancing the structural strength and elasticity of the conductive spring.
[0026] In one possible implementation, the second component includes a component body and a contact member. The contact member is fixed to the component body and electrically conductive, and the contact portion contacts the contact member. Thus, the second component is formed by assembling the component body and the contact member. The component body and the contact member can be made of different materials. For example, the component body can be made of a material with high structural strength and low cost (such as steel), and the contact member can be made of a material with a higher conductivity than the component body. This achieves a balance between manufacturing cost and conductive efficiency.
[0027] In one possible implementation, a second recessed groove is provided on the surface of the component body facing the first component, and the contact member is accommodated within the second recessed groove. This recessed placement of the contact member within the component body avoids any overlap between the component body and the contact member, facilitating a thinner electronic device. Furthermore, the contact member can contact not only the bottom surface of the second recessed groove but also the side surfaces of the second recessed groove, thereby increasing the contact area between the contact member and the component body and improving the electrical conductivity between the contact member and the component body.
[0028] In one possible implementation, the contact includes a contact body and a second contact layer. The second contact layer is disposed at least on the surface of the contact body facing the first component, and the conductivity of the second contact layer is greater than that of the contact body. The second end portion is in electrical contact with the second contact layer. This second contact layer improves the electrical conductivity between the contact body and the second component, reducing impedance and passive intermodulation characteristics.
[0029] In one possible implementation, the electronic device further includes at least one fixing member connected between the first component and the second component. The at least one fixing member is located on the side of the sealing ring facing away from the conductive member. This allows the conductive member and the sealing ring to be positioned independently of the fixing member, allowing them to be positioned where there is ample space, thereby avoiding impacting the size of the second component and the stability of the connection between the first and second components.
[0030] In one possible implementation, the fixing member is a screw. Screws offer superior connection stability and reliability. Furthermore, the threaded surface of the screw may be provided with an insulating coating, which prevents the first component and the second component from being electrically connected together via the screw.
[0031] In one possible implementation, the first component has a threaded hole, and the second component has a first through-hole, which is opposite the threaded hole. Insulating material is provided between the first and second components, and the insulating material has a relief hole, which is opposite and connected to the through-hole and the threaded hole. The screw includes a head and a shaft, with the head located on the side of the second component facing away from the first component, and the shaft accommodated within the first through-hole, the relief hole, and the threaded hole. In this way, the insulating material prevents direct contact between the second component and the first component at the location of the fixing, thus preventing corrosion.
[0032] In one possible implementation, a boss is provided between the first component and the second component, the boss being connected to one of the first and second components, and an insulating material being disposed between the boss and the other of the first and second components. A second via is provided within the boss, the second via being opposite and connected to the first via, the avoidance hole, and the threaded hole, and the rod is accommodated within the first, second vias, the avoidance hole, and the threaded hole. In this manner, the boss can increase the gap height between the first and second components, preventing other areas of the first surface from contacting other areas of the second surface, thereby reducing the risk of corrosion. Furthermore, the boss can prevent the flatness of the first and second surfaces from affecting the connection reliability between the first and second components.
[0033] In one possible implementation, there are multiple fixing parts, and the multiple fixing parts are connected between the edge of the second part and the first part. The conductive part and the sealing ring are located on the side of the multiple fixing parts facing the center of the second part. In this way, the spacing between the multiple fixing parts is large. When the rotating shaft mechanism rotates, the resistance force arm of the multiple fixing parts is large, and the resistance torque generated is large, which can effectively prevent the second part from separating from the first part and ensure the connection stability between the second part and the first part. At the same time, since the conductive part and the sealing ring are located on the side of the multiple fixing parts facing the center of the second part, it can be avoided that the conductive part and the sealing ring affect the size of the second part and the connection stability between the first part and the second part.
[0034] In one possible implementation, at least one of the first component and the second component is made of a magnesium alloy. Magnesium alloy has a low density, good structural strength and rigidity, and is beneficial for reducing the weight of the electronic device and ensuring the structural strength and service life of the electronic device.
[0035] In one possible implementation, the electronic device includes a first middle frame and a hinge mechanism. The hinge mechanism includes a base, a first swing arm, and a first connector. The first swing arm is rotatably connected to the base, the first connector is connected to the end of the first swing arm away from the base, and the first connector is fixed to the first middle frame. The first middle frame forms the first component, and the first connector forms the second component. Alternatively, the first middle frame forms the second component, and the first connector forms the first component. In this way, the electronic device is a folding screen device, which can reduce the weight of the folding screen device. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0051] In the embodiments of the present application, the description that two components are “electrically conductive” means that when one of the two components is energized, the current on the one component can enter the other component through the electrically conductive portion.
[0052] The present application provides an electronic device, which may be a user equipment (UE) or a terminal device, for example, the electronic device may be a tablet computer (portable android device, PAD), a laptop computer, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and other mobile terminals or fixed terminals. The electronic device includes at least two components, and the two components are electrically conductive with each other by means of a conductive member. The embodiments below are exemplified by taking the electronic device as a folding screen device, which may be, for example, a mobile phone.
[0053] Please refer to Figures 1 and 2. Figure 1 is a three-dimensional diagram of the electronic device 10 provided in some embodiments of the present application in the unfolded state, and Figure 2 is a schematic diagram of the partial decomposition structure of the electronic device 10 shown in Figure 1. The electronic device 10 is approximately in the shape of a rectangular flat plate in the unfolded state. In order to facilitate the description of the various embodiments below, an XYZ coordinate system is established for the electronic device 10 in the unfolded state, and the length direction of the electronic device 10 is defined as the X-axis direction, the width direction of the electronic device 10 is defined as the Y-axis direction, and the thickness direction of the electronic device 10 is defined as the Z-axis direction. It can be understood that the coordinate system setting of the electronic device 10 can be flexibly set according to actual needs and is not specifically limited here. In some other embodiments, the shape of the electronic device 10 in the unfolded state can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.
[0054] The electronic device 10 includes a folding screen 1 and a supporting device 2 .
[0055] The foldable screen 1 is used to display images, videos, and other information. The foldable screen 1 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (OLED) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD), and the like.
[0056] The foldable screen 1 has a display surface that is exposed to facilitate presenting images, videos, and other information to the user. The foldable screen 1 includes a first foldable screen portion 11, a second foldable screen portion 12, and a third foldable screen portion 13. The third foldable screen portion 13 is connected between the first foldable screen portion 11 and the second foldable screen portion 12. In the electronic device 10 shown in Figure 1, the foldable screen 1 is in the unfolded state, with the first foldable screen portion 11, the third foldable screen portion 13, and the second foldable screen portion 12 arranged sequentially along the X-axis, such that the electronic device 10 folds in the horizontal direction. In other embodiments, when the foldable screen 1 is in the unfolded state, the first foldable screen portion 11, the third foldable screen portion 13, and the second foldable screen portion 12 may also be arranged sequentially along the Y-axis, such that the electronic device 10 folds in the vertical direction. When the foldable screen 1 is in the unfolded state, it can achieve a large-screen display, providing users with richer information and a better user experience.
[0057] At least the third foldable screen portion 13 of the foldable screen 1 is a flexible screen structure. As such, the third foldable screen portion 13 can bend and deform under external force, allowing the foldable screen 1 to fold from the unfolded state shown in Figure 1 to the folded state. The first foldable screen portion 11 and the second foldable screen portion 12 of the foldable screen 1 can be flexible screen structures, rigid screen structures, or partially flexible and partially rigid screen structures, without specific limitation herein.
[0058] Please refer to Figure 3, which is a schematic structural diagram of the electronic device 10 shown in Figure 1 when it is in a folded state, and the folding screen 1 in the electronic device 10 is also in a folded state. Specifically, when the folding screen 1 is in a folded state, the first folding screen part 11 and the second folding screen part 12 of the folding screen 1 are approximately parallel and opposite. Among them, the angle θ between the first folding screen part 11 and the second folding screen part 12 is within 30°, and the first folding screen part 11 and the second folding screen part 12 can be considered to be approximately parallel. The first folding screen part 11 and the second folding screen part 12 being opposite means that the display surface of the first folding screen part 11 and the display surface of the second folding screen part 12 face each other.
[0059] The supporting device 2 is located on the side of the folding screen 1 facing away from the display surface, and is used to support the folding screen 1 .
[0060] The support device 2 includes a first housing 21, a second housing 22, and a hinge mechanism 23. The first housing 21 supports the first folding screen portion 11, and the second housing 22 supports the second folding screen portion 12. The hinge mechanism 23 is connected between the first and second housings 21, 22, and supports the third folding screen portion 13. The hinge mechanism 23 is used to achieve rotation between the second housing 22 and the first housing 21, thereby supporting the folding screen 1 between the unfolded state and the folded state.
[0061] When the electronic device 10 is in a folded state, please continue to refer to Figure 3. The supporting device 2 is protected outside the folding screen 1, and the folding screen 1 is invisible to the user, which can prevent the folding screen 1 from being scratched by hard objects. The folding screen device is an inward-folding folding screen device, and the size of the electronic device 10 is reduced, making it easy to carry.
[0062] In the above embodiment, optionally, the first shell 21 may include a first middle frame and a first back cover connected together. The above-mentioned first folding screen part 11 is carried on the first middle frame, and the first back cover is located on the side of the first middle frame facing away from the first folding screen part 11, and the first back cover can be replaced with a display screen (such as an LCD display screen). A first accommodating cavity is formed between the first middle frame and the first back cover, and the first accommodating cavity is used to accommodate components such as a first circuit board, a camera module, and a battery, which are fixed to the first middle frame. On this basis, the first shell 21 can be connected to the hinge mechanism 23 with the help of the first middle frame.
[0063] Similarly, the second shell 22 may also include a second middle frame and a second back cover connected together. The above-mentioned second folding screen part 12 is carried on the second middle frame, and the second back cover is located on the side of the second middle frame facing away from the second folding screen part 12, and the second back cover may also be replaced with a display screen (such as an LCD display screen). A second accommodating cavity is formed between the second middle frame and the second back cover, and the second accommodating cavity is used to accommodate components such as a second circuit board, a speaker module, an array, a battery, etc., which are fixed to the second middle frame. On this basis, the second shell 22 can be connected to the hinge mechanism 23 with the help of the second middle frame.
[0064] It should be noted that, in order to distinguish the first middle frame from the second middle frame, in the description of each embodiment below, the first middle frame is labeled A in the drawings and the second middle frame is labeled B in the drawings.
[0065] Please refer to Figure 4, which is a schematic diagram of the back structure of the first middle frame A, the second middle frame B, and the hinge mechanism 23 in the electronic device 10 shown in Figures 1 and 2. The back refers to the surface of the first middle frame A, the second middle frame B, and the hinge mechanism 23 that faces away from the foldable screen 1.
[0066] According to the description of the above embodiment, the first middle frame A is used to carry the first folding screen part 11 and fix the components in the first accommodating cavity, and the second middle frame B is used to carry the second folding screen part 12 and fix the components in the second accommodating cavity. Therefore, the first middle frame A and the second middle frame B play a supporting role. Based on this, in order to ensure the supporting strength of the first middle frame A and the second middle frame B. The first middle frame A and the second middle frame B can be made of metal materials, such as aluminum alloy. At the same time, the first middle frame A and the second middle frame B are also used as reference grounds to meet the signal return requirements of the components in the first accommodating cavity and the second accommodating cavity.
[0067] Part of the materials of the first middle frame A and the second middle frame B can also be used as the radiator of the antenna (not shown in the figure) to realize the transmission and reception of radio frequency signals.
[0068] Continuing to refer to FIG. 4 , the rotating shaft mechanism 23 includes a base 231 , a first swing arm 232 , a second swing arm 233 , a first connecting member 234 and a second connecting member 235 .
[0069] It should be noted that FIG4 schematically illustrates some of the components included in the hinge mechanism 23. These components are shown in FIG4 as simplified diagrams and do not limit the actual shape, size, position, or structure of these components. In some embodiments, the hinge mechanism 23 may include, in addition to the aforementioned components, a shaft cover, a door panel, an auxiliary swing arm, etc., which are not described in detail in this application.
[0070] The base 231 provides a position reference within the rotating shaft mechanism 23, and the base 231 can also be called a center beam. The first swing arm 232 and the second swing arm 233 are rotatably connected to the base 231. The number of the first swing arm 232 and the second swing arm 233 can be one or more. In the embodiment shown in Figure 4, the number of the first swing arm 232 and the second swing arm 233 are three. The rotation axis of the first swing arm 232 relative to the base 231 and the rotation axis of the second swing arm 233 relative to the base 231 are roughly parallel. Here, "roughly parallel" means parallelism that allows a certain error range, and the error range can be a range within 5° relative to absolute parallel deviation.
[0071] The first connecting member 234 and the second connecting member 235 are also referred to as wedge blocks.
[0072] The first connecting member 234 is connected to one end of the first swing arm 232 away from the base 231 , and the first connecting member 234 is fixed to the first middle frame A. The connection between the first connecting member 234 and the first swing arm 232 includes but is not limited to a fixed connection, a sliding connection, and a rotating connection.
[0073] Similarly, the second connecting member 235 is connected to the end of the second swing arm 233 away from the base 231, and the second connecting member 235 is fixed to the second middle frame B. The connection method between the second connecting member 235 and the second swing arm 233 includes but is not limited to a fixed connection, a sliding connection, and a rotating connection.
[0074] When the first middle frame A and the second middle frame B are subjected to a force from a user, they can drive the first swing arm 232 and the second swing arm 233 to rotate relative to the base 231, so that the electronic device 10 can switch between the unfolded state and the folded state.
[0075] In order to ensure the life of the electronic device 10 and improve the reliability of the movement of the hinge mechanism 23, the hinge mechanism 23 is usually made of metal material. For example, the hinge mechanism 23 is made of steel, and the steel material includes but is not limited to stainless steel.
[0076] Based on the above embodiment, the hinge mechanism 23 can be electrically connected to the first and second middle frames A and B to prevent the hinge mechanism 23 from absorbing the radiation efficiency of the antennas on the first and second middle frames A and B. Furthermore, the hinge mechanism 23 can also discharge static electricity from the hinge mechanism 23 to the first and second middle frames A and B, preventing power outages and thus preventing interference with electronic components within the electronic device 10, such as the first and second circuit boards, the camera module, and the display screen. Furthermore, the hinge mechanism 23 can also be electrically connected to the first and second middle frames A and B, placing the first and second middle frames A and B at the same potential, preventing a potential difference between the first and second middle frames A and B. This prevents the generation of an electric field between the first and second middle frames A and B, and further prevents interference with radio frequency and baseband signals transmitted on the flexible printed circuit (FPC). The FPC is connected between the first circuit board in the first accommodating cavity and the second circuit board in the second accommodating cavity, passing through the hinge mechanism 23.
[0077] To achieve the above purpose, the first connecting member 234 is fixed to the first middle frame A and electrically connected to the first middle frame A, and the second connecting member 235 is fixed to the second middle frame B and electrically connected to the second middle frame B.
[0078] For more details, please refer to Figure 5, which is a schematic cross-sectional view of the assembly structure shown in Figure 4 along the AA axis. The first middle frame A and the first connector 234 are secured together with screws K. The surface of the first connector 234 facing the first middle frame A is provided with a boss 2341. The boss 2341 and the first connector 234 are integrally formed and made of the same steel material. The screw K is inserted into the boss 2341. The locking force of the screw K ensures that the boss 2341 and the first middle frame A are in close contact, achieving electrical continuity between the first middle frame A and the first connector 234.
[0079] Similarly, the connection method between the second connecting member 235 and the second middle frame B can be implemented with reference to the fixing method between the first connecting member 234 and the first middle frame A, and will not be described in detail here.
[0080] With technological advancements, electronic devices 10 are required to be increasingly lightweight. To achieve this goal, the first and second middle frames A and B within the electronic device can be formed from magnesium alloy. Magnesium alloys are alloys composed of magnesium with other elements added. They have low density but excellent rigidity and strength, ensuring the structural strength of the first and second middle frames A and B while achieving weight reduction. Furthermore, magnesium alloys are abundant in raw material resources, which helps reduce the cost of electronic devices.
[0081] However, magnesium alloys are highly chemically active and have a very low equilibrium potential. Galvanic corrosion is easily induced when in contact with dissimilar metals in a humid or solution environment. Furthermore, the hinge mechanism 23 is a moving mechanism, which is difficult to seal. Moist air or moisture outside the electronic device can easily enter the space where the hinge mechanism 23 is located, and then enter the gap between the first connector 234 and the first middle frame A, and between the second connector 235 and the second middle frame B. Furthermore, as described above, the material of the boss 2341 is steel, which is different from the material of the first middle frame A and the second middle frame B. Therefore, the portion of the first middle frame A that contacts the boss 2341, and the portion of the second middle frame B that contacts the boss of the second connector 235, will corrode. Corrosion of the magnesium alloy increases impedance and reduces the reliability of the electrical connection.
[0082] To address the above issues, please refer to Figures 6-8. Figure 6 is a schematic diagram of a portion of the structure of an electronic device 10 provided in some embodiments of the present application. Figure 7 is a partially enlarged view of area I of the electronic device 10 shown in Figure 6. Figure 8 is a schematic diagram of the cross-sectional structure of the electronic device 10 along line BB shown in Figure 7. In this embodiment, the electronic device 10 includes a first component 3 and a second component 4.
[0083] The first component 3 and the second component 4 can be in the form of a plate, sheet, block, etc. This application uses the first component 3 and the second component 4 as plates for illustrative purposes. The first component 3 and the second component 4 are made of a conductive material. Specifically, the first component 3 and the second component 4 can be made of a conductive metal.
[0084] In some embodiments, referring to FIG. 6 and FIG. 7 , the first component 3 may be the first middle frame A described above, and the second component 4 may be the first connecting member 234 described above.
[0085] In some other embodiments, the first component 3 can also be the above-mentioned first connecting member 234, and the second component 4 can be the above-mentioned first middle frame A, or the first component 3 can be the above-mentioned second middle frame B, and the second component 4 can be the above-mentioned second connecting member 235, or the first component 3 can be the above-mentioned second connecting member 235, and the second component 4 can be the above-mentioned second middle frame B.
[0086] In yet other embodiments, when the electronic device 10 is a product other than a folding screen device, the first component 3 and the second component 4 may also be other components.
[0087] This embodiment and the following embodiments are illustrative in that the first component 3 is the above-mentioned first middle frame A and the second component 4 is the above-mentioned first connecting member 234. This cannot be regarded as a special limitation on the structural form of the first component 3 and the second component 4.
[0088] Please refer to FIG. 7 and FIG. 8 . The electronic device 10 further includes a conductive member 5 and a sealing ring 6 .
[0089] The conductive member 5 is disposed between the first component 3 and the second component 4 and is electrically connected to the first component 3 and the second component 4 .
[0090] The sealing ring 6 is disposed between the first component 3 and the second component 4 , with one axial end of the sealing ring 6 facing the first component 3 and the other end facing the second component 4 .
[0091] The sealing ring 6 can be made of materials including, but not limited to, foam, rubber, and silicone. The axial direction of the sealing ring 6 refers to the direction of extension of the central axis of the cylindrical space surrounded by the sealing ring 6. The shape of the sealing ring 6 can be circular, square, polygonal, triangular, rectangular, and the like. Please refer to Figure 9, which is a top view of the conductive element 5 and sealing ring 6 in the electronic device 10 shown in Figure 8. The sealing ring 6 is generally rectangular in shape.
[0092] In some embodiments, referring to FIG. 8 , the surface of the first component 3 facing the second component 4 is defined as the first surface S1 , the surface of the second component 4 facing the first component 3 is defined as the second surface S2 , and the first sealing ring 6 is disposed between the first surface S1 and the second surface S2 .
[0093] Based on the above, the sealing ring 6 can be fixed to the first surface by gluing, hot pressing, or other processes, with the sealing ring 6 in contact with the second surface S2 but not connected. Alternatively, the sealing ring 6 can be fixed to the second surface S2 by gluing, hot pressing, or other processes, with the sealing ring 6 in contact with the first surface S1 but not connected. This facilitates separation of the first and second components 3, 4 for maintenance and facilitates installation of the sealing ring 6 between the first and second components 3, 4. Furthermore, it can secure the position of the sealing ring 6 between the first and second components 3, 4, preventing misalignment.
[0094] In some other embodiments, the first surface S1 and / or the second surface S2 may be provided with an annular limiting groove, in which at least a portion of the sealing ring 6 is accommodated. The sealing ring 6 is thereby limited by the annular limiting groove, which can also prevent the sealing ring 6 from being misplaced.
[0095] Based on the above, please refer to FIG. 9 , the conductive member 5 is located in the area surrounded by the sealing ring 6 .
[0096] In this way, electrical conduction between the first component 3 and the second component 4 can be achieved with the help of the conductive member 5, and the electrical conduction portion between the first component 3 and the second component 4 can be sealed with the help of the sealing ring 6 to prevent moisture from entering, avoid corrosion, and ensure the reliability of the electrical connection, so that the first component 3 or the second component 4 can be selected from chemically active metals such as magnesium alloys, thereby increasing the material selection range of the first component 3 and the second component 4, which is conducive to reducing the weight of the electronic device 10.
[0097] On the basis of the above, optionally, at least one of the first component 3 and the second component 4 is made of magnesium alloy. Magnesium alloy has a low density and good structural strength and rigidity, which is beneficial to reducing the weight of the electronic device 10 and ensuring the structural strength and service life of the electronic device 10.
[0098] The conductive part 5 includes but is not limited to a conductive boss, a conductive gasket, a conductive spring, etc., and the material of the conductive part 5 includes but is not limited to metals such as stainless steel, spring steel, aluminum alloy, magnesium alloy, titanium alloy, and non-metals such as graphite and graphene. The conductive part 5 can also be rubber doped with metal particles or graphite particles.
[0099] Since the conductive part 5 is located in the area surrounded by the sealing ring 6, the area occupied by the conductive part 5 in the XY plane affects the size of the sealing ring 6. Specifically, the smaller the area occupied by the conductive part 5 in the XY plane, the smaller the sealing ring 6, and the smaller the impact on the size of the first component 3 and the second component 4 in the XY plane. At the same time, since the conductive part 5 is located between the first component 3 and the second component 4, the height of the conductive part 5 in the Z-axis direction affects the height of the sealing ring 6 and also affects the stacking thickness of the first component 3 and the second component 4. Specifically, the smaller the height of the conductive part 5 in the Z-axis direction, the smaller the height of the sealing ring 6, the lower the material cost and sealing difficulty, the smaller the stacking thickness of the first component 3 and the second component 4, and the more conducive to the thinning of the electronic device.
[0100] In some embodiments, referring to Figures 8 and 9 , the conductive member 5 is a conductive spring. The conductive spring is relatively small, making it easy to install between the first component 3 and the second component 4 in a limited space. It also contributes to the thinning of the electronic device and avoids affecting the size of the first component 3 and the second component 4.
[0101] There are many structural forms of the conductive spring. In some embodiments, referring to FIG8 , the conductive spring includes a fixing portion 51 , an elastic arm portion 52 and a contact portion 53 .
[0102] The fixing portion 51 is fixed to the first component 3 and electrically connected thereto. In some embodiments, the fixing portion 51 can be fixed to the first component 3 and electrically connected thereto by spot welding, or by using a conductive adhesive and electrically connected thereto. This application uses the example of the fixing portion 51 being fixed to the first component 3 and electrically connected thereto by spot welding, and this is not to be construed as a special limitation on this application.
[0103] In some embodiments, referring to FIG8 , a first recessed groove C1 is defined on the first surface S1, and at least the fixing portion 51 of the conductive spring is received within the recessed groove C1. This allows the height of the conductive spring in the Z-axis direction to be increased, while maintaining a constant gap height between the first component 3 and the second component 4, thereby enhancing the structural strength and elasticity of the conductive spring.
[0104] On the basis of the above, the fixing portion 51 is fixed to the bottom surface of the first sink C1 by spot welding and is electrically connected to the first component 3 .
[0105] In some embodiments, referring to FIG8 , the first sink C1 can be disposed in the area of the first surface S1 surrounded by the sealing ring 6. This avoids step differences in the location of the sealing ring 6 on the first surface S1, thereby ensuring the sealing performance of the sealing ring 6 and preventing corrosion.
[0106] In some embodiments, the depth of the first recessed groove C1 can be greater than or equal to 0.1 mm and less than or equal to 0.2 mm. Specifically, the depth of the first recessed groove C1 can be 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, or 0.2 mm. When the depth of the first recessed groove C1 is within this range, the depth of the first recessed groove C1 is moderate, which can increase the height of the conductive spring in the Z-axis direction while avoiding affecting the structural strength of the first component 3.
[0107] The contact portion 53 is in electrical contact with the second component 4. In some embodiments, the contact portion 53 may include a contact portion body and a first contact layer (not shown). The first contact layer is disposed on the surface of the contact portion body, and the conductivity of the first contact layer is greater than that of the contact portion body. The first contact layer is in electrical contact with the second component 4.
[0108] In this way, with the help of the first contact layer, the conductive efficiency between the contact portion body and the second component 4 can be improved, and the impedance and passive inter-modulation (PIM) characteristics can be reduced.
[0109] In the above embodiment, the material of the first contact layer includes, but is not limited to, at least one of gold, nickel, silver, and copper. In some embodiments, the material of the first contact layer is gold, which has high conductivity and can significantly improve the electrical conductivity between the contact portion body and the second component 4, thereby reducing impedance and PIM characteristics.
[0110] The first contact layer can be formed on the surface of the contact portion body by using processes such as electroplating, vacuum plating, and thermal spraying, and this application does not make any specific limitation on this.
[0111] Continuing to refer to FIG8 , the elastic arm portion 52 includes a first end portion 521 and a second end portion 522 relative to each other. The direction from the first end portion 521 to the second end portion 522 is inclined relative to the first surface S1. The direction from the first end portion 521 to the second end portion 522 is parallel to the line i connecting the first end portion 521 and the second end portion 522 in FIG8 . Specifically, the inclination angle of the direction from the first end portion 521 to the second end portion 522 relative to the first surface S1 can be greater than 0° and less than 90°, and can specifically be 15°, 30°, 45°, 60°, 80°, etc., and this application does not impose any specific limitation on this.
[0112] It should be noted that in the above-mentioned embodiment and the following embodiments, the term "two opposite ends" of a component refers to portions adjacent to two opposite edges of the component, one edge being located on the side of one end away from the other end, and the other edge being located on the side of the other end away from the one end. Therefore, the direction from one end to the other end of the two ends refers to the direction from the midpoint of the one edge to the midpoint of the other edge.
[0113] For example, please refer to Figure 10, which is a schematic diagram of the structure of the conductive member 5 in the structure shown in Figure 9. The elastic arm portion 52 includes a sixth edge L6 and a first edge L1 that are opposite to each other; the sixth edge L6 is located on the side of the first end portion 521 away from the second end portion 522 and is adjacent to the first end portion 521; the first edge L1 is located on the side of the second end portion 522 away from the first end portion 521 and is adjacent to the second end portion 522. Based on this, the direction from the first end portion 521 to the second end portion 522 refers to the direction from the midpoint O1 of the sixth edge L6 to the midpoint O2 of the first edge L1. In the embodiments below, the same description should be understood in the same way, and will not be repeated here.
[0114] Based on the above, the first end 521 is connected to the fixing portion 51 and is electrically connected. The second end 522 is connected to the contact portion 53 and is electrically connected. Specifically, the second end 522 is connected to the contact portion body of the contact portion 53 and is electrically connected.
[0115] In this way, during the installation of the conductive spring between the first component 3 and the second component 4, the elastic arm portion 52 can bend toward the first component 3, thereby accumulating elastic force. This elastic force can stabilize the contact portion 53 against the second component 4, thereby ensuring reliable contact between the contact portion 53 and the second component 4. Furthermore, the conductive spring can be adapted for installation between different gaps. Due to its small thickness, the conductive spring can be installed within gaps with limited height, without affecting the thickness of the electronic device, thus facilitating thinning of the electronic device.
[0116] It is understandable that the size of the conductive spring affects the size of the first component 3 and the second component 4, as well as the thickness of the electronic device. Specifically, the larger the orthographic projection area of the conductive spring on the XY plane, the larger the dimensions of the first component 3 and the second component 4 in the X-axis and Y-axis directions need to be designed. This allows the first component 3 and the second component 4 to shield the conductive spring, preventing exposure, while also facilitating a stable electrical connection between the first component 3 and the second component 4. The greater the height of the conductive spring in the Z-axis, the greater the stacking thickness of the first component 3, the conductive spring, and the second component 4 in the Z-axis, making it less conducive to the thinning design of the electronic device.
[0117] Based on this, in some embodiments, referring to FIG10 , the fixing portion 51 includes a third end portion 511 and a fourth end portion 512 that are opposite to each other. The direction from the third end portion 511 to the fourth end portion 512 is a first direction D1. The first direction D1 is parallel to the first surface S1. For example, referring to FIG10 , the first direction D1 is opposite to the Y-axis direction.
[0118] Based on the above, please continue to refer to FIG. 10 , the first end portion 521 is connected to the fourth end portion 512 and is electrically conductive.
[0119] Please refer to Figure 11, which is a schematic diagram of the orthographic projection of the conductive member 5 shown in Figure 10 onto the first surface S1. The orthographic projection of the first end 521 onto the first surface S1 is a first orthographic projection X1, and the orthographic projection of the second end 522 onto the first surface S1 is a second orthographic projection X2. The direction from the first orthographic projection X1 to the second orthographic projection X2 is a second direction D2, which is opposite to the first direction D1. The term "opposite" does not necessarily mean absolutely opposite, but rather refers to being approximately opposite within a certain tolerance.
[0120] In this way, the conductive spring is bent in the opposite direction at least once along the path from the third end 511 → the fourth end 512 → the first end 521 → the second end 522, thereby reducing the size of the conductive spring in the first direction D1, avoiding the first component 3 and the second component 4 from being designed too large in the first direction D1, and thus helping to reduce the size of the electronic device.
[0121] Based on the above embodiment, a direction parallel to the first surface S1 and perpendicular to the first direction D1 is defined as a third direction D3. The fixing portion 51 and the elastic arm portion 52 can be arranged along the Z-axis direction or along the third direction D3. This application does not make any specific restrictions on this.
[0122] In some embodiments, please continue to refer to FIG. 10 , the fixing portion 51 and the elastic arm portion 52 are arranged at intervals along the third direction D3 .
[0123] In this way, the orthographic projection area of the fixing portion 51 on the first surface S1 and the orthographic projection area of the elastic arm portion 52 on the first surface S1 do not overlap, which can avoid the thickness overlap of the fixing portion 51 and the elastic arm portion 52 in the Z-axis direction, which is beneficial to reducing the height of the conductive spring in the Z-axis direction, thereby reducing the stacking thickness of the first component 3, the conductive spring and the second component 4 in the Z-axis direction, which is beneficial to the thin design of the electronic device.
[0124] In some embodiments, referring to FIG. 10 , the conductive spring further includes a connecting portion 54. The connecting portion 54 is located between the fourth end portion 512 and the first end portion 521. The connecting portion 54 is electrically connected to both the fourth end portion 512 and the first end portion 521. Furthermore, the connecting portion 54 extends along the third direction D3 from the fourth end portion 512 to the first end portion 521.
[0125] In this way, the fourth end portion 512 and the first end portion 521 are aligned in the third direction D3 , which can further reduce the size of the conductive spring in the first direction D1 .
[0126] In some embodiments, referring to FIG. 10 and FIG. 11 , the orthographic projection of the elastic arm portion 52 on the first surface S1 is a third projection X3 , and the length of the third projection X3 in the first direction D1 is smaller than the length of the fixing portion 51 in the first direction D1 .
[0127] In this way, since the contact portion 53 is connected to the second end portion 522, the fourth end portion 512 and the first end portion 521 are aligned in the third direction D3. The contact portion 53 is located in the middle position of the conductive spring in the first direction D1, and the area surrounded by the sealing ring 6 on the second surface S2 is defined as the first area. In this way, the contact portion 53 can be in contact with the middle position of the first area in the first direction D1, which can further ensure the reliability of the electrical connection.
[0128] Based on the above embodiments, the contact portion 53 can be arranged on the side of the second end 522 away from the first end 521, or can be arranged on the second end 522, or can be arranged on the side of the second end 522 facing the fixed portion 51, or can be arranged on the side of the second end 522 facing away from the fixed portion 51.
[0129] 10 , the edge of the second end 522 away from the first end 521 is the first edge L1, and the portion of the second end 522 where the first edge L1 is located forms the contact portion 53. In this way, the conductive spring has a simple structure and is easy to manufacture.
[0130] Based on the above embodiment, optionally, referring to FIG10 , the edge of the second end portion 522 facing the fixing portion 51 is a second edge L2, which is a flange protruding toward the fixing portion 51. The edge of the second end portion 522 away from the fixing portion 51 is a third edge L3, and a circular transition edge or an inclined transition edge is connected to the first edge L1.
[0131] When a circular arc transition edge C is connected between the third edge L3 and the first edge L1 , refer to FIG. 10 . The circular arc transition edge C protrudes away from the fixing portion 51 and is tangent to both the first edge L1 and the third edge L3 .
[0132] When an inclined transition edge is connected between the third edge L3 and the first edge L1, one end of the inclined transition edge is connected to the third edge L3, and the other end extends away from the first end portion 521 and tilts toward the fixing portion 51, and the other end is connected to the first edge L1.
[0133] In this way, in the third direction D3, the contact portion 53 is closer to the fixed portion 51, that is, the contact portion 53 is located in the middle position of the conductive spring in the third direction D3, so that the contact portion 53 can contact the middle position of the above-mentioned first area in the third direction D3, which is conducive to ensuring the stability and reliability of the electrical connection.
[0134] In some embodiments, referring to Figure 10 , a first relief notch a1 is defined on the edge of the fixing portion 51 facing the elastic arm portion 52. When the elastic arm portion 52 bends toward the first component 3 to be coplanar with the fixing portion 51, the first relief notch a1 is aligned with the second edge L2 along the third direction D3.
[0135] In this way, the first relief notch a1 allows for a portion of the second end portion 522 at the second edge L2 to be avoided, preventing the elastic arm portion 52 from overlapping with the fixing portion 51 in the Z-axis direction when the elastic arm portion 52 is bent to be coplanar with the fixing portion 51, thereby further reducing the thickness of the conductive spring. Furthermore, the first relief notch a1 allows for a portion of the elastic arm portion 522 to be avoided, reducing the distance between the elastic arm portion 52 and the fixing portion 51 in the third direction D3 and reducing the size of the conductive spring in the third direction D3.
[0136] It can be seen that the elastic force of the conductive spring is generated by the deformation of the elastic arm portion 52. Please continue to refer to Figure 10. The portion of the elastic arm portion 52 located between the first end portion 521 and the second end portion 522 is defined as the middle portion 523. The structural strength of the elastic arm portion 52 is determined by the width W of the intersection between the first end portion 521 and the middle portion 523. The larger the width W, the higher the structural strength of the elastic arm portion 522, the less likely it is to deform, and the greater the elastic force generated after deformation.
[0137] Based on this, in some embodiments, please continue to refer to FIG10 , the elastic arm portion 52 further includes a middle section 5231 . The middle section 5231 is connected between the first end portion 521 and the second end portion 522 .
[0138] The middle section 5231 may be a section of the middle part 523 or the entire middle part 523 . This application exemplifies the middle section 5231 as a section of the middle part 523 .
[0139] Continuing with Figure 10 , the edge of the middle section 5231 facing the fixing portion 51 is defined as the fourth edge L4, and the edge of the connecting portion 54 facing the gap between the middle section 5231 and the fixing portion 51 is defined as the fifth edge L5. The fourth edge L4 and the fifth edge L5 are connected, and along the direction from the second end 522 to the first end 521, the fourth edge L4 is inclined toward the fixing portion 51.
[0140] In this way, the width W of the boundary between the first end portion 521 and the middle portion 523 is larger, the structural strength of the elastic arm portion 52 is higher, and the elastic force is greater, so that the contact portion 53 can reliably contact the second component 4.
[0141] Based on the above embodiment, referring to Figure 10 , a second relief notch a2 is provided on the edge of the fixing portion 51 facing the elastic arm portion 52. When the elastic arm portion 52 bends toward the first component 3 to be coplanar with the fixing portion 51, the second relief notch a2 is opposite the fourth edge L4 along the third direction D3.
[0142] In this way, the second relief notch a2 allows for a portion of the middle section 5231 at the fourth edge L4 to be avoided, preventing the elastic arm portion 52 from overlapping with the fixing portion 51 in the Z-axis direction when the elastic arm portion 52 is bent to be coplanar with the fixing portion 51, thereby further reducing the thickness of the conductive spring. Furthermore, the second relief notch a2 allows for a portion of the middle section 5231 at the fourth edge L4 to be avoided, reducing the distance between the elastic arm portion 52 and the fixing portion 51 in the third direction D3 and thus reducing the size of the conductive spring in the third direction D3.
[0143] In some embodiments, please refer to Figure 10, the fixing portion 51, the connecting portion 54, the elastic arm portion 52 and the contact portion body can be formed as one piece, or can be fixed by welding. This application is exemplified by the fixing portion 51, the connecting portion 54, the elastic arm portion 52 and the contact portion body being formed as one piece, which cannot be regarded as a special limitation to this application.
[0144] In some embodiments, referring to Figures 8 and 10 , the fixing portion 51 , the connecting portion 54 , and the first end portion 521 of the elastic arm portion 52 can be accommodated in the first recess C1 , with the fixing portion 51 being fixed to the bottom surface of the first recess C1 . This structure is simple and easy to implement.
[0145] Based on any of the above embodiments, the second component 4 can be an integral structural member, or can be formed by assembling multiple structural members, which is not specifically limited in this application.
[0146] 8 , in some embodiments, the second component 4 may include a component body 41 and a contact member 42 . The contact member 42 is fixed to the component body 41 and electrically connected thereto, and the contact portion 53 is in contact with the contact member 42 .
[0147] In this way, the second component 4 is formed by assembling a component body 41 and a contact piece 42. The component body 41 and the contact piece 42 can be made of different materials. For example, the component body 41 can be made of a material with high structural strength and low cost (such as stainless steel), and the contact piece 42 can be made of a material with a conductivity greater than that of the component body 41, thereby balancing the production cost and conductive efficiency.
[0148] In the above embodiment, the contact member 42 can be recessed within the component body 41 or protruded from the surface of the component body 41. In some embodiments, referring to FIG8 , a second recessed groove C2 is provided on the surface of the component body 41 facing the first component 3. The contact member 42 is accommodated in the second recessed groove C2.
[0149] Thus, the contact member 42 is sunken within the component body 41, thereby avoiding any overlap in thickness between the component body 41 and the contact member 42, which facilitates the thinning of the electronic device. Furthermore, the contact member 42 can contact not only the bottom surface of the second recessed groove C2, but also the side surfaces of the second recessed groove C2. This increases the contact area between the contact member 42 and the component body 41, thereby improving the electrical conductivity between the contact member 42 and the component body 41.
[0150] In some embodiments, the contact member 42 can be fixed to the bottom surface of the second sink C2 by spot welding, conductive adhesive bonding, etc. This connection method is simple and easy to operate.
[0151] In the above embodiment, the surface of the component body 41 facing the first component 3 and the surface of the contact member 42 facing the first component 3 are joined to form the aforementioned second surface S2. Therefore, the second recessed groove C2 is positioned within the area of the second surface S2 surrounded by the sealing ring 6. This prevents any step difference in the location of the sealing ring 6 on the second surface S2, thereby ensuring the sealing performance of the sealing ring 6 and preventing corrosion.
[0152] In some embodiments, as shown in FIG8 , the depth of the second recessed groove C2 is greater than or equal to 0.1 mm and less than or equal to 0.2 mm. Specifically, the depth of the second recessed groove C2 can be 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, or 0.2 mm. When the depth of the second recessed groove C2 falls within this range, the depth of the second recessed groove C2 is moderate, facilitating the thinning of the electronic device while avoiding compromising the structural strength of the component body 41.
[0153] In some embodiments, referring to FIG8 , the thickness of the contact member 42 can be greater than or equal to 0.05 mm and less than or equal to 0.15 mm. Thus, the thickness of the contact member 42 is moderate, ensuring the structural strength of the contact member 42 while being able to be sunk in the second sinking groove C2.
[0154] In some embodiments, the contact 42 can be made of a single material or multiple materials. In some embodiments, referring to FIG. 8 , the contact 42 can include a contact body 421 and a second contact layer 422. The second contact layer 422 is disposed at least on the surface of the contact body 421 facing the first component 3, and the conductivity of the second contact layer 422 is greater than that of the contact body 421. Consequently, the second end portion 522 is in contact with and electrically connected to the second contact layer 422. This second contact layer 422 improves the electrical conductivity between the contact body and the second component 4, reducing impedance and PIM characteristics.
[0155] The material of the contact body 421 includes, but is not limited to, copper, copper alloys, aluminum alloys, magnesium alloys, and the like. In some embodiments, the conductivity of the contact body 421 is greater than that of the component body 41. This improves the electrical conductivity from the contact body 421 to the component body 41, reducing impedance and PIM characteristics.
[0156] The material of the second contact layer 422 includes, but is not limited to, at least one of gold, nickel, silver, and copper. In some embodiments, the material of the second contact layer 422 is gold. Gold has a high conductivity and can significantly improve the electrical conductivity between the conductive element 5 and the second component 4, thereby reducing impedance and PIM characteristics.
[0157] The second contact layer 422 may be provided only on the surface of the contact body 421 facing the first component 3 and not on other surfaces of the contact body 421. The second contact layer 422 may also be provided on all surfaces of the contact body 421, or on at least two surfaces including the surface facing the first component 3. This application does not specifically limit this. This application exemplifies that the second contact layer 422 is provided only on the surface of the contact body 421 facing the first component 3, and this should not be considered a special limitation of this application.
[0158] The first component 3 is fixedly connected to the second component 4. In some embodiments, referring back to FIG. 7 , the electronic device 10 further includes at least one fixing member 7 . "At least one" refers to one or more than two. The at least one fixing member 7 is connected between the first component 3 and the second component 4 . The first component 3 is fixedly connected to the second component 4 by means of the at least one fixing member 7 .
[0159] Based on the above, optionally, at least one fixing member 7 is located on a side of the sealing ring 6 facing away from the conductive member 5 .
[0160] In this way, the conductive part 5 and the sealing ring 6 are not restricted by the position of the fixing part 7. The conductive part 5 and the sealing ring 6 can be set at a position with ample space to avoid affecting the size of the second component 4 and the connection stability between the first component 3 and the second component 4.
[0161] In the above embodiment, the number of fixing members 7 can be one or more. In some embodiments, referring to FIG7 , there are multiple fixing members 7 , and multiple fixing members 7 are connected between the edge of the second component 4 and the first component 3 . The conductive member 5 and the sealing ring 6 are located on one side of the multiple fixing members 7 facing the center of the second component 4 .
[0162] In this way, the spacing between the multiple fixing members 7 is relatively large. When the rotating shaft mechanism 23 rotates, the resistance arm of the multiple fixing members 7 is relatively large, and the resistance torque generated is relatively large, which can effectively prevent the second component 4 from separating from the first component 3 and ensure the stability of the connection between the second component 4 and the first component 3. At the same time, because the conductive member 5 and the sealing ring 6 are located on the side of the multiple fixing portions 7 facing the center of the second component 4, the conductive member 5 and the sealing ring 6 can be prevented from affecting the size of the second component 4 and the stability of the connection between the first component 3 and the second component 4.
[0163] In any of the above embodiments, the fixing member 7 includes, but is not limited to, screws, bolts, rivets, and clips. This application uses a screw as the fixing member 7 for illustrative purposes. When the fixing member 7 is a screw, the connection between the first component 3 and the second component 4 is more stable and reliable. Furthermore, the threaded surface of the screw may be provided with an insulating coating to prevent the first component 3 and the second component 4 from being electrically connected via the screw.
[0164] Specifically, see Figure 12, which is a partial, enlarged view of region II of the electronic device 10 shown in Figure 8. The first component 3 is provided with a threaded hole h1, and the second component 4 is provided with a first via hole h2, which is opposite to the threaded hole h1. An insulating material 8 is provided between the first component 3 and the second component 4. The insulating material 8 may be made of materials including, but not limited to, mylar, rubber, and silicone. The insulating material 8 is provided with a relief hole h3, which is opposite to and communicates with the first via hole h2 and the threaded hole h1.
[0165] The screw 7 includes a head and a shank. The head is located on the side of the second component 4 facing away from the first component 3 , and the shank is accommodated in the first through hole h2 , the avoidance hole h3 and the threaded hole h1 .
[0166] In this way, with the help of the insulating material 8, direct contact between the second component 4 and the first component 3 at the location of the fixing member 7 can be avoided, thereby preventing corrosion.
[0167] In some embodiments, referring to FIG. 12 , the thickness of insulating material 8 can be greater than or equal to 0.03 mm and less than or equal to 0.1 mm. When the thickness of insulating material 8 is within this range, insulation performance is guaranteed, effectively preventing contact between first component 3 and second component 4 at fixing portion 7 . Furthermore, insulating material 8 is prevented from increasing the stack thickness, facilitating a thinner electronic device 10 .
[0168] In some embodiments, referring to FIG12 , a boss 43 is provided between the first component 3 and the second component 4 . The boss 43 is connected to one of the first component 3 and the second component 4 , and the insulating material 8 is provided between the boss 43 and the other of the first component 3 and the second component 4 .
[0169] For example, referring to FIG. 12 , the boss 43 can be connected to the second component 4 . The boss 43 can be integrally formed with the component body 41 of the second component 4 , or can be connected to the component body 41 by gluing, welding, or other methods, which are not specifically limited in this application. The insulating material 8 is disposed between the first component 3 and the boss 43 .
[0170] In other examples, the boss 43 may be connected to the first component 3. The boss 43 may be integrally formed with the first component 3 or connected to the first component 3 by gluing, welding, or other methods. This application does not specifically limit this. The insulating material 8 is disposed between the second component 4 and the boss 43.
[0171] Based on any of the above embodiments, a second through hole h4 is provided in the boss 43. The second through hole h4 is opposite to and communicates with the first through hole h2, the avoidance hole h3, and the threaded hole h1. The shaft of the screw 7 is accommodated in the first through hole h2, the second through hole h4, the avoidance hole h3, and the threaded hole h1.
[0172] In this way, the boss 43 can increase the gap height between the first component 3 and the second component 4, preventing other areas of the first surface S1 from contacting other areas of the second surface S2, thereby reducing the risk of corrosion. In addition, the boss 43 can prevent the flatness of the first surface S1 and the second surface S2 from affecting the connection reliability between the first component 3 and the second component 4.
[0173] In some embodiments, referring to FIG12 , the height of the boss 4 can be greater than or equal to 0.03 mm and less than or equal to 0.2 mm. When the height of the boss 4 is within this range, the gap between the first component 3 and the second component 4 is moderate. This not only reduces the stacking thickness of the first component 3 and the second component 4, but also effectively prevents contact between other areas of the first surface S1 and other areas of the second surface S2, thereby reducing the risk of corrosion.
[0174] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
