Description

Technical Field

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

[0002] Foldable electronic devices can adopt an outward folding design, that is, when the electronic device is in a closed state, the screen bends to form the appearance of the electronic device, while the back cover folds and is located inside the screen.

[0003] In outward-folding designs, electronic devices typically include a shielding component. When the electronic device is unfolded, the shielding component covers the gap created between the back cover and the device, thereby shielding and protecting the internal structure. However, in existing technologies, the shielding component occupies too much space and cannot effectively shield the internal structure of the electronic device, thus reducing its dustproof and waterproof performance. Summary of the Invention

[0004] This application discloses a foldable electronic device, a folding assembly, and a housing device. The electronic device includes a first housing, a second housing, and a folding assembly. The folding assembly is connected between the first and second housings and is movable to allow the electronic device to be in an open and closed state. The folding assembly includes a connecting assembly, a shielding member, and a pivot assembly. The connecting assembly can drive the shielding member to move relative to the pivot assembly. When the electronic device is in the closed state, the connecting assembly can drive the shielding member to fold relative to the pivot assembly and retract it inside the housing, without occupying additional space. When the electronic device is in the open state, the connecting assembly can drive the shielding member to unfold relative to the pivot assembly, thereby shielding and protecting the internal structure of the electronic device and improving its dustproof and waterproof performance.

[0005] In a first aspect, this application provides a foldable electronic device. The electronic device has an open state and a closed state, and includes a housing device and a screen, with the screen mounted on the housing device; the housing device includes a folding assembly, a first housing, and a second housing, with the folding assembly connected between the first housing and the second housing, and the folding assembly is movable to allow the electronic device to be in the open state and the closed state.

[0006] The folding assembly includes a first shielding member, a second shielding member, a first connecting assembly, a second connecting assembly, and a main shaft. The first connecting assembly and the second connecting assembly are rotatably connected to both sides of the main shaft, respectively. The first shielding member is slidably connected to the first connecting assembly, and the second shielding member is slidably connected to the second connecting assembly. During the movement of the electronic device, the first connecting assembly and the first shielding member rotate relative to the main shaft, and the second connecting assembly and the second shielding member rotate relative to the main shaft.

[0007] During the process of the electronic device moving from the open state to the closed state, the first shielding member and the second shielding member fold relative to each other. The first shielding member slides away from the main shaft relative to the first connecting assembly, and the second shielding member slides away from the main shaft relative to the second connecting assembly. During the process of the electronic device moving from the closed state to the open state, the first shielding member and the second shielding member unfold relative to each other. The first shielding member slides towards the main shaft relative to the first connecting assembly, and the second shielding member slides towards the main shaft relative to the second connecting assembly, so as to shield the main shaft, thereby shielding and protecting the internal structure of the electronic device and improving the dustproof and waterproof performance of the electronic device.

[0008] In one possible implementation, the first connecting component includes a first rotating member and a first elastic member. The first rotating member is rotatably connected to the main shaft, the first shielding member is slidably connected to the first rotating member, and the first elastic member connects the first shielding member and the first rotating member.

[0009] In this implementation, the first elastic element is used to provide a first elastic force, which drives the first shielding element to slide relative to the first rotating element towards the main shaft.

[0010] In one possible implementation, the folding assembly includes a first slider, the upper side of which is fixedly connected to a first shielding member, and the lower side of which is slidably connected to a first rotating member.

[0011] In this implementation, the first shielding component is slidably connected to the first connecting assembly via the first sliding component, which facilitates the maintenance and replacement of the first shielding component and reduces costs.

[0012] In one possible implementation, the first rotating member is provided with a second receiving groove, the first elastic member is installed in the second receiving groove, the first sliding member includes a first actuating member, the first actuating member is at least partially located in the second receiving groove, and the first elastic member contacts or abuts against the first actuating member and the groove wall of the second receiving groove.

[0013] In this implementation, the first sliding member presses the first elastic member by the first actuating member, causing it to deform and generate elastic force, thereby driving the first shielding member to slide relative to the first rotating member.

[0014] In one possible implementation, the first connecting component includes a first damping element that connects the first rotating component and the main shaft, and is used to provide damping force during the rotation of the first rotating component relative to the main shaft.

[0015] In this implementation, the first damping element can provide damping force to the movement of the first rotating element relative to the main shaft, so as to provide a damping feel.

[0016] In one possible implementation, the first rotating member is provided with a first receiving groove, and the first damping member includes a bracket and an elastic member. The bracket includes a proximal end and a distal end disposed opposite to each other. The proximal end of the bracket contacts or abuts the main shaft, and the distal end of the bracket and the elastic member are installed in the first receiving groove. One end of the elastic member is connected to the distal end of the bracket, and the other end contacts or abuts the groove wall of the first receiving groove.

[0017] In this implementation, during the movement from the closed state to the open state, the proximal end of the bracket of the first damping member abuts against the limiting member of the main shaft of the rotating shaft assembly. The limiting member pushes the distal end of the bracket to move away from the main shaft, and the elastic member is compressed so that the first rotating member of the first connecting assembly passes the limiting member and continues to move towards the main shaft. The elastic force generated by the elastic member increases the friction between the proximal end and the limiting member, thereby providing damping force during the rotation of the first rotating member relative to the main shaft.

[0018] In one possible implementation, the proximal end of the support includes a sleeve and a rotating shaft, the sleeve being fitted onto the rotating shaft and rotatable relative to the rotating shaft, the sleeve contacting or abutting the main shaft.

[0019] In this implementation, the sleeve can slide relative to the limiting member to reduce the frictional resistance between the first damping member and the limiting member.

[0020] In one possible implementation, the folding assembly includes a pivot assembly, which includes a main shaft, a first support member, a second support member, a first gear connecting rod, and a second gear connecting rod. The first support member and the second support member are rotatably connected to both sides of the main shaft, respectively.

[0021] In this implementation, the first support member, the second support member, and the main shaft form a hinge assembly. The hinge assembly is movable to unfold or fold the electronic device. When the electronic device is in the open state, the first and second support members can be flattened relative to the main shaft to provide a flat support environment. When the electronic device is in the closed state, the first and second support members can be folded relative to the main shaft, together forming an arc-shaped support surface to support the center of the screen, allowing the center of the screen to exhibit a natural curvature, preventing creases, ensuring the screen's display and touch sensing effects, reducing the risk of screen damage, and extending the screen's lifespan.

[0022] In one possible implementation, the folding assembly further includes a first fixing member and a second fixing member, wherein the first fixing member is rotatably connected to the first support member, and the second fixing member is rotatably connected to the second support member.

[0023] In this implementation, the overall structure of the hinge assembly, which consists of the hinge assembly, the first fixing member, and the second fixing member, is complete and has good stability, thereby providing a stable support environment for the screen and ensuring the screen's display performance and touch control performance.

[0024] In one possible implementation, the first gear connecting rod includes a rotating end and a sliding end disposed opposite to each other. The rotating end of the first gear connecting rod is rotatably connected to the main shaft, and the sliding end of the first gear connecting rod is slidably connected to the first fixing member. The second gear connecting rod includes a rotating end and a sliding end disposed opposite to each other. The rotating end of the second gear connecting rod is rotatably connected to the main shaft, and the sliding end of the second gear connecting rod is slidably connected to the second fixing member. The rotating end of the first gear connecting rod meshes with the rotating end of the second gear connecting rod.

[0025] In this implementation, the rotating end of the first gear connecting rod meshes with the rotating end of the second gear connecting rod. Therefore, the rotation angle of the gear end of the first gear connecting rod is the same in magnitude and opposite in direction to the rotation angle of the gear end of the second gear connecting rod, so that the rotation of the first gear connecting rod and the second gear connecting rod relative to the main shaft of the rotating shaft assembly is synchronized, that is, they move closer to each other or further away from each other synchronously.

[0026] In one possible implementation, the first connecting component is slidably connected to the first fixing member, and the second connecting component is slidably connected to the second fixing member.

[0027] In this implementation, when in the open state, the first fixing member and the second fixing member are flattened relative to the rotating shaft assembly; when in the closed state, the first fixing member slides relative to the first connecting assembly toward the rotating shaft assembly, and the second fixing member slides relative to the second connecting assembly toward the rotating shaft assembly.

[0028] Secondly, this application provides a folding assembly having an open state and a closed state. The folding assembly includes a first shielding member, a second shielding member, a first connecting assembly, a second connecting assembly, and a main shaft. The first connecting assembly and the second connecting assembly are rotatably connected to both sides of the main shaft, respectively. The first shielding member is slidably connected to the first connecting assembly, and the second shielding member is slidably connected to the second connecting assembly. During the movement of the folding assembly, the first connecting assembly and the first shielding member rotate relative to the main shaft, and the second connecting assembly and the second shielding member also rotate relative to the main shaft.

[0029] During the movement of the folding assembly from the open state to the closed state, the first and second shielding members fold relative to each other. The first shielding member slides away from the main axis relative to the first connecting assembly, and the second shielding member slides away from the main axis relative to the second connecting assembly. During the movement of the folding assembly from the closed state to the open state, the first and second shielding members unfold relative to each other. The first shielding member slides towards the main axis relative to the first connecting assembly, and the second shielding member slides towards the main axis relative to the second connecting assembly, thereby shielding the main axis and protecting the internal structure of the folding assembly, thus improving the dustproof and waterproof performance of the folding assembly.

[0030] In one possible implementation, the first connecting component includes a first rotating member and a first elastic member. The first rotating member is rotatably connected to the main shaft, the first shielding member is slidably connected to the first rotating member, and the first elastic member connects the first shielding member and the first rotating member.

[0031] In this implementation, the first elastic element is used to provide a first elastic force, which drives the first shielding element to slide relative to the first rotating element towards the main shaft.

[0032] In one possible implementation, the folding assembly includes a first slider, the upper side of which is fixedly connected to a first shielding member, and the lower side of which is slidably connected to a first rotating member.

[0033] In this implementation, the first shielding component is slidably connected to the first connecting assembly via the first sliding component, which facilitates the maintenance and replacement of the first shielding component and reduces costs.

[0034] In one possible implementation, the first rotating member is provided with a second receiving groove, the first elastic member is installed in the second receiving groove, the first sliding member includes a first actuating member, the first actuating member is at least partially located in the second receiving groove, and the first elastic member contacts or abuts against the first actuating member and the groove wall of the second receiving groove.

[0035] In this implementation, the first sliding member presses the first elastic member by the first actuating member, causing it to deform and generate elastic force, thereby driving the first shielding member to slide relative to the first rotating member.

[0036] In one possible implementation, the first connecting component includes a first damping element that connects the first rotating component and the main shaft, and is used to provide damping force during the rotation of the first rotating component relative to the main shaft.

[0037] In this implementation, the first damping element can provide damping force to the movement of the first rotating element relative to the main shaft, so as to provide a damping feel.

[0038] In one possible implementation, the first rotating member is provided with a first receiving groove, and the first damping member includes a bracket and an elastic member. The bracket includes a proximal end and a distal end disposed opposite to each other. The proximal end of the bracket contacts or abuts the main shaft, and the distal end of the bracket and the elastic member are installed in the first receiving groove. One end of the elastic member is connected to the distal end of the bracket, and the other end contacts or abuts the groove wall of the first receiving groove.

[0039] In this implementation, during the movement from the closed state to the open state, the proximal end of the bracket of the first damping member abuts against the limiting member of the main shaft of the rotating shaft assembly. The limiting member pushes the distal end of the bracket to move away from the main shaft, and the elastic member is compressed so that the first rotating member of the first connecting assembly passes the limiting member and continues to move towards the main shaft. The elastic force generated by the elastic member increases the friction between the proximal end and the limiting member, thereby providing damping force during the rotation of the first rotating member relative to the main shaft.

[0040] In one possible implementation, the proximal end of the support includes a sleeve and a rotating shaft, the sleeve being fitted onto the rotating shaft and rotatable relative to the rotating shaft, the sleeve contacting or abutting the main shaft.

[0041] In this implementation, the sleeve can slide relative to the limiting member to reduce the frictional resistance between the first damping member and the limiting member.

[0042] In one possible implementation, the folding assembly includes a pivot assembly, which includes a main shaft, a first support member, a second support member, a first gear connecting rod, and a second gear connecting rod. The first support member and the second support member are rotatably connected to both sides of the main shaft, respectively. The folding assembly also includes a first fixing member and a second fixing member, with the first fixing member rotatably connected to the first support member and the second fixing member rotatably connected to the second support member.

[0043] In this implementation, the overall structure of the hinge assembly, which consists of the hinge assembly, the first fixing member, and the second fixing member, is complete and has good stability, thereby providing a stable support environment for the screen and ensuring the screen's display performance and touch control performance.

[0044] In one possible implementation, the first gear connecting rod includes a rotating end and a sliding end disposed opposite to each other. The rotating end of the first gear connecting rod is rotatably connected to the main shaft, and the sliding end of the first gear connecting rod is slidably connected to the first fixing member. The second gear connecting rod includes a rotating end and a sliding end disposed opposite to each other. The rotating end of the second gear connecting rod is rotatably connected to the main shaft, and the sliding end of the second gear connecting rod is slidably connected to the second fixing member. The rotating end of the first gear connecting rod meshes with the rotating end of the second gear connecting rod.

[0045] In this implementation, the rotating end of the first gear connecting rod meshes with the rotating end of the second gear connecting rod. Therefore, the rotation angle of the gear end of the first gear connecting rod is the same in magnitude and opposite in direction to the rotation angle of the gear end of the second gear connecting rod, so that the rotation of the first gear connecting rod and the second gear connecting rod relative to the main shaft of the rotating shaft assembly is synchronized, that is, they move closer to each other or further away from each other synchronously.

[0046] In one possible implementation, the first connecting component is slidably connected to the first fixing member, and the second connecting component is slidably connected to the second fixing member.

[0047] In this implementation, when in the open state, the first fixing member and the second fixing member are flattened relative to the rotating shaft assembly; when in the closed state, the first fixing member slides relative to the first connecting assembly toward the rotating shaft assembly, and the second fixing member slides relative to the second connecting assembly toward the rotating shaft assembly.

[0048] Thirdly, this application provides a housing device for use in foldable electronic devices. The housing device includes a first housing, a second housing, and a folding assembly, the folding assembly connecting the first housing and the second housing, the first housing and the second housing being able to be unfolded or folded relative to each other via the folding assembly.

[0049] In this application, the folding assembly connects the first housing and the second housing. Through the structural design of the folding assembly, the first housing and the second housing can be unfolded when the electronic device is in the open state and folded when the electronic device is in the closed state. Thus, the first housing and the second housing, together with the folding assembly, can provide a support environment for the screen to ensure the reliability of the screen and reduce the risk of screen damage.

[0050] In one possible implementation, when the first housing and the second housing are folded relative to each other to a closed state, the first shielding member is at least partially retracted into the first housing, and the second shielding member is at least partially retracted into the second housing.

[0051] In this implementation, the first shielding member is at least partially retracted into the first housing, and the second shielding member is at least partially retracted into the second housing, without occupying additional space, thus making the structure of the housing device compact.

[0136] The embodiments of this application are described below with reference to the accompanying drawings. In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. It should be understood that when component A is fixedly connected to component C via component B, changes in the relative positional relationship due to deformation of components A, B, and C are permitted. "Rotary connection" refers to a connection where components can rotate relative to each other after connection. "Sliding connection" refers to a connection where components can slide relative to each other after connection. The integrated structure obtained by a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components.

[0139] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 in the open state according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 1000 when it is in the closed state.

[0140] In some embodiments, the electronic device 1000 includes a housing 300 and a screen 200, the screen 200 being mounted on the housing 300. For example... Figure 1 As shown, the housing device 300 can be unfolded to the open state; as Figure 2As shown, the housing device 300 can also be folded into a closed state. Furthermore, the housing device 300 can also be unfolded or folded into an intermediate state, which can be any state between the open and closed states. The screen 200 moves with the housing device 300, which can cause the screen 200 to unfold or fold, allowing the electronic device 1000 to unfold into an open state or fold into a closed state. When the electronic device 1000 is in the closed state, the housing device 300 is located inside the screen 200.

[0141] In this embodiment, when the electronic device 1000 is in the open state, the screen 200 is flattened and can display in full screen, giving the electronic device 1000 a larger display area to improve the user's viewing and operating experience. When the electronic device 1000 is in the closed state, its planar dimensions are smaller, making it easier for users to carry and store.

[0142] In some embodiments, screen 200 may integrate display and touch sensing functions. The display function of screen 200 is used to display images, videos, etc., and the touch sensing function of screen 200 is used to sense user touch actions to achieve human-computer interaction. For example, screen 200 includes a flexible display screen that can be bent. The flexible display screen can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a flex light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0143] In some embodiments, the electronic device 1000 may further include multiple components (not shown in the figures), which are installed inside the housing device 300. These 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, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0144] It should be understood that in this embodiment, the electronic device 1000 is described as having a two-fold structure, that is, the electronic device 1000 includes two flat plate parts and a bent portion connecting the two flat plate parts; the two flat plate parts can rotate towards each other to overlap each other (corresponding to the closed state mentioned above), so that the electronic device 1000 presents a two-layer form; the two flat plate parts can also rotate away from each other to flatten out (corresponding to the open state mentioned above). In some other embodiments, the electronic device 1000 may also have a three-fold or more-fold structure, that is, the electronic device 1000 includes three or more flat plate parts, and two adjacent flat plate parts are connected by a bent portion, and two adjacent flat plate parts can rotate relative to each other to overlap each other or rotate away from each other to flatten out. When the electronic device 1000 has a three-fold or more-fold structure, the structure of the electronic device 1000 can be adapted to the description of the two-fold structure in this embodiment, and will not be described again in this application.

[0145] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 , Figure 3 yes Figure 1 A partially exploded view of the electronic device 1000 when it is in the open state.

[0146] In some embodiments, the housing device 300 includes a folding assembly 1, a first housing 2, and a second housing 3. The folding assembly 1 can connect the first housing 2 and the second housing 3. The first housing 2 and the second housing 3 can be unfolded or folded relative to each other via the folding assembly 1. It should be understood that when the electronic device 1000 is in the open state, the screen 200, the housing device 300, and each component of the housing device 300 are correspondingly in the open state; when the electronic device 1000 is in the closed state, the screen 200, the housing device 300, and each component of the housing device 300 are correspondingly in the closed state.

[0147] When the electronic device 1000 is in the open state, the angle between the first housing 2 and the second housing 3 can be approximately 180°, with the first housing 2 and the second housing 3 flattened, and the screen 200 in a flattened state. In some other embodiments, when the electronic device 1000 is in the open state, the angle between the first housing 2 and the second housing 3 may deviate slightly from 180°, such as 165°, 177°, or 185°, and in this case, the first housing 2 and the second housing 3 are also considered to be flattened. The angle between the first housing 2 and the second housing 3 is defined as the angle between the side of the first housing 2 facing the screen 200 and the side of the second housing 3 facing the screen 200. The screen 200 can move with the first housing 2, the folding assembly 1, and the second housing 3, thereby achieving unfolding and folding. When the electronic device 1000 is in the closed state, the angle between the first housing 2 and the second housing 3 can be approximately 0°, with the first housing 2 and the second housing 3 folded, and the screen 200 in a folded state.

[0148] The first housing 2 and the second housing 3 are housing components used to install and fix other components of the electronic device 1000. They have diverse structures. This application embodiment only briefly illustrates some of the structures of the first housing 2 and the second housing 3. The accompanying drawings are also simplified. This application embodiment does not strictly limit the specific structure of the first housing 2 and the second housing 3.

[0149] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 4 yes Figure 2 The schematic diagram of the housing device 300 shown.

[0150] In some embodiments, the folding assembly 1 forms a support surface 4 on the side facing the screen 200. Exemplarily, the support surface 4 of the folding assembly 1 may include a plane 42 located in the center and curved surfaces (41, 43) located on both sides. Figure 3 As shown, when the electronic device 1000 is in the open state, curved surfaces 41 and 43 can be flattened relative to the plane 42 to provide a flat support environment. Figure 2 and Figure 4 As shown, when the electronic device 1000 is in a closed state, the curved surfaces 41 and 43 can be tilted relative to the plane 42 to form an arc-shaped support surface 4, which provides support for the middle part of the screen 200, so that the middle part of the screen 200 presents a natural curvature, avoids creases on the screen 200, ensures the display effect and touch sensing effect of the screen 200, reduces the risk of damage to the screen 200, and extends the service life of the screen 200.

[0151] Please refer to the following: Figure 5 and Figure 6 , Figure 5yes Figure 1 The diagram shows the structure of the electronic device 1000 from another angle. Figure 6 yes Figure 5 A partial exploded view of the electronic device 1000 shown.

[0152] In some embodiments, the first housing 2 may include a first back cover 21 and a first middle frame 22, and the second housing 3 may include a second back cover 31 and a second middle frame 32. The first middle frame 22 and the second middle frame 32 may be fixedly connected to both sides of the folding assembly 1. The first back cover 21 may be located on the side of the first middle frame 22 away from the screen 200 and fixedly connected to the first middle frame 22. The second back cover 31 may be located on the side of the second middle frame 32 away from the screen 200 and fixedly connected to the second middle frame 32. For example, the first back cover 21 and / or the second back cover 31 may be protective covers for protecting devices located inside the first housing 2 and for presenting part of the appearance of the electronic device 1000. In other embodiments, the first back cover 21 may also include a transparent cover and a display screen to realize display functions and / or touch functions.

[0153] The first middle frame 22 and / or the second middle frame 32 may include metal and plastic parts, and are integrally formed by in-mold decoration (IMD) molding. When the first back cover 21 and / or the second back cover 31 are protective covers, they may be made of glass or metal materials, and this application does not impose strict limitations on this.

[0154] The first middle frame 22 and the second middle frame 32 both include a frame portion and a middle plate portion. The frame portion forms part of the appearance of the electronic device 1000. The middle plate portion is located inside the frame portion. The middle plate portion may be provided with multiple protrusions, grooves and other mounting structures for cooperating with other components of the electronic device 1000 so that the other parts are mounted on the first housing 2 and / or the second housing 3.

[0155] In this application, the external structure of the side of the folding component 1 facing away from the screen 200 can, together with the frame portion of the first middle frame 22, the first back cover 21, the frame portion of the second middle frame 32, and the second back cover 31, form part of the appearance of the electronic device 1000, providing protection and shielding for the internal structure of the electronic device 1000, and making the electronic device 1000 aesthetically pleasing.

[0156] The external components of the electronic device 1000 may have multiple through-holes, which enable various components installed within the housing 300 to interact with the outside of the electronic device 1000. These through-holes may include, but are not limited to: a USB port corresponding to a USB interface, a camera hole corresponding to a camera, a speaker hole corresponding to a speaker, a receiver hole corresponding to a receiver, a microphone hole corresponding to a microphone, a headphone jack corresponding to a headphone jack, button holes corresponding to buttons, indicator light holes corresponding to indicators, and a SIM card slot corresponding to a SIM card interface. The number of each type of through-hole may be one or more, and the external components may include fewer or more types of through-holes. The external components of the electronic device 1000 may also include multiple non-signal shielding areas, allowing the antenna to transmit and receive electromagnetic waves through these areas.

[0157] In this application, the folding assembly 1 connects the first housing 2 and the second housing 3. Through the structural design of the folding assembly 1, the first housing 2 and the second housing 3 can be unfolded when the electronic device 1000 is in the open state and folded when the electronic device 1000 is in the closed state. Thus, the first housing 2 and the second housing 3, together with the folding assembly 1, can provide a supporting environment for the screen 200, ensuring the reliability of the screen 200 and reducing the risk of damage to the screen 200. The following provides an example illustrating the implementation structure of the folding assembly 1.

[0158] Please refer to the following: Figure 6 and Figure 7 , Figure 7 yes Figure 6 A partial exploded view of the folding component 1 shown.

[0159] In some embodiments, the folding assembly 1 may include a pivot assembly 10, a first fixing member 15, a second fixing member 16, a first shielding member 17, a second shielding member 18, and multiple connecting components (11, 12, 13, 14). The pivot assembly 10, the first fixing member 15, and the second fixing member 16 together form the main motion mechanism of the folding assembly 1. The multiple connecting components (11, 12, 13, 14) are rotatably connected to the pivot assembly 10 and can drive the first shielding member 17 and the second shielding member 18 to move relative to the pivot assembly 10.

[0160] The first fixing member 15 and the second fixing member 16 are respectively connected to both sides of the rotating shaft assembly 10. The first fixing member 15 and the second fixing member 16 are deformable, allowing them to unfold or fold relative to the rotating shaft assembly 10. The first fixing member 15 and the second fixing member 16 are also respectively connected between the first housing 2, the second housing 3, and the rotating shaft assembly 10 (see reference). Figure 6When the first fixing member 15 and the second fixing member 16 deform relative to the rotating shaft assembly 10, the first housing 2 and the second housing 3 deform relative to the rotating shaft assembly 10 to unfold or fold relative to each other.

[0161] The hinge assembly 10 may be provided with protective components 19 at its top and bottom. These protective components 19 may surround the edge of the screen 200 to jointly protect the edge of the screen 200, reducing the risk of damage such as warping and improving the reliability of the screen 200. In this embodiment, the two ends near the hinge assembly 10 are defined as the top and bottom ends, respectively, and the direction from the top to the bottom of the hinge assembly 10 is the extension direction of the hinge assembly 10; the orientation near the top of the hinge assembly 10 is defined as "top," and the orientation near the bottom of the hinge assembly 10 is defined as "bottom."

[0162] The plurality of connecting components (11, 12, 13, 14) includes a first connecting component 11, a second connecting component 12, a third connecting component 13, and a fourth connecting component 14. The first connecting component 11 and the second connecting component 12 are rotatably connected to the top two sides of the rotating shaft assembly 10, respectively, while the third connecting component 13 and the fourth connecting component 14 are rotatably connected to the bottom two sides of the rotating shaft assembly 10, respectively. A first shielding member 17 is slidably connected to the first connecting component 11 and the second connecting component 12, and a second shielding member 18 is slidably connected to the third connecting component 13 and the fourth connecting component 14. The first connecting component 11 and the third connecting component 13 are slidably connected to a first fixing member 15, and the second connecting component 12 and the fourth connecting component 14 are slidably connected to a second fixing member 16. When the plurality of connecting components (11, 12, 13, 14) deform relative to the rotating shaft assembly 10, the first fixing member 15 and the second fixing member 16 move relative to the rotating shaft assembly 10 to unfold or fold relative to the rotating shaft assembly 10. Understandably, in this application, the multiple connecting components include four connecting components (11, 12, 13, 14) as an example for illustration. In other embodiments, the multiple connecting components may also include other numbers of connecting components, such as two, three, six, etc., as long as at least one connecting component is connected to each side of the rotating shaft assembly 10. This application does not limit this.

[0163] For example, the folding assembly 1 may further include multiple sliders (110, 120, 130, 140), each corresponding one-to-one with a multiple connecting assembly (11, 12, 13, 14), for connecting the multiple connecting assemblies (11, 12, 13, 14) and the shielding member (17, 18). For example, the multiple sliders (110, 120, 130, 140) may include a first slider 110, a second slider 120, a third slider 130, and a fourth slider 140.

[0164] In this application, the pivot assembly 10, the first fixing member 15, and the second fixing member 16 together form the main motion mechanism of the folding assembly 1. Multiple connecting components (11, 12, 13, 14) deform with the movement of the main motion mechanism to drive the first shielding member 17 and the second shielding member 18 to move relative to the pivot assembly 10. The first shielding member 17 and the second shielding member 18, together with the first rear cover 21 and the second rear cover 31, constitute part of the exterior components of the electronic device 1000, providing protection for the internal structure of the electronic device 1000.

[0165] Next, we will first give an example of the structure of the main motion mechanism (rotating shaft assembly 10, first fixing member 15 and second fixing member 16) of the folding assembly 1.

[0166] Please refer to the following: Figure 3 , Figure 4 and Figure 8 , Figure 8 yes Figure 7 A partially exploded view of the rotating shaft assembly 10 shown.

[0167] In some embodiments, the pivot assembly 10 includes a main shaft 100, a first support 104, a second support 105, and a plurality of gear links (106, 107, 108, 109). The main shaft 100 of the pivot assembly 10 may include a top shaft 101, a middle shaft 102, and a bottom shaft 103, which can be assembled to form the main shaft 100 of the pivot assembly 10 for easy disassembly and maintenance. For example, the bottom end of the top shaft 101 is provided with an assembly 1010, the top and bottom ends of the middle shaft 102 are both provided with assembly grooves 1020, and the top end of the bottom shaft 103 is provided with an assembly 1030. The assembly 1010 at the bottom end of the top shaft 101 can cooperate with the assembly groove 1020 at the top end of the middle shaft 102, and the assembly groove 1020 at the bottom end of the middle shaft 102 can cooperate with the assembly 1030 at the top end of the bottom shaft 103. They are fastened by fasteners to realize the assembly of the top shaft 101, the middle shaft 102 and the bottom shaft 103, and make the connection between them firm.

[0168] In some other embodiments, the top shaft 101, the middle shaft 102, and the bottom shaft 103 may also be an integral structure to improve the structural stability of the spindle 100 of the shaft assembly 10.

[0169] The first support member 104 and the second support member 105 are rotatably connected to the two sides of the main shaft 100, respectively. Specifically, the first support member 104 is rotatably connected to one side of the main shaft 100, and the second support member 105 is rotatably connected to the other side of the main shaft 100. The first support member 104 and the second support member 105 are deformable, allowing them to flatten or fold relative to the main shaft 100 of the rotating shaft assembly 10. A first fixing member 15 is rotatably connected to the first support member 104, and a second fixing member 16 is rotatably connected to the second support member 105. When the first support member 104 and the second support member 105 deform relative to the main shaft 100 of the rotating shaft assembly 10, the first fixing member 15 and the second fixing member 16 move with the first support member 104 and the second support member 105, allowing them to flatten or fold relative to each other.

[0170] The first support member 104 may include multiple rotating connectors (1042, 1043, 1045, 1047, 1048) and multiple mating connectors (1041, 1044, 1046, 1049). The first support member 104 connects the main shaft 100 of the rotating shaft assembly 10 and the first fixing member 15 through the multiple rotating connectors and the multiple mating connectors. The multiple rotating connectors (1042, 1043, 1045, 1047, 1048) include a second connector 1042, a third connector 1043, a fifth connector 1045, a seventh connector 1047, and an eighth connector 1048. The multiple mating connectors (1041, 1044, 1046, 1049) include a first connector 1041, a fourth connector 1044, a sixth connector 1046, and a ninth connector 1049. The first connector 1041, the second connector 1042, and the third connector 1043 are disposed on the top of the first support 104 and are all connected to the top shaft 101; the fourth connector 1044, the fifth connector 1045, and the sixth connector 1046 are disposed in the middle of the first support 104 and are all connected to the central shaft 102; the seventh connector 1047, the eighth connector 1048, and the ninth connector 1049 are disposed at the bottom of the first support 104 and are all connected to the bottom shaft 103.

[0171] Understandably, this application uses five rotating connectors as an example for illustration, but the number of rotating connectors can also be other numbers. Similarly, this application uses four mating connectors as an example for illustration, but the number of mating connectors can also be other numbers, and this application does not limit this. In some other embodiments, the first support member 104 may not include mating connectors, and this application does not limit this.

[0172] The second support member 105 may also include multiple rotating connectors (1052, 1053, 1055, 1057, 1058) and multiple mating connectors (1051, 1054, 1056, 1059). The second support member 105 connects the main shaft 100 of the rotating shaft assembly 10 and the second fixing member 16 through the multiple rotating connectors and the multiple mating connectors. The multiple rotating connectors (1052, 1053, 1055, 1057, 1058) include the second connector 1052, the third connector 1053, the fifth connector 1055, the seventh connector 1057, and the eighth connector 1058. The multiple mating connectors (1051, 1054, 1056, 1059) include the first connector 1051, the fourth connector 1054, the sixth connector 1056, and the ninth connector 1059. The first connector 1051, the second connector 1052, and the third connector 1053 are disposed on the top of the second support 105 and are all connected to the top shaft 101; the fourth connector 1054, the fifth connector 1055, and the sixth connector 1056 are disposed in the middle of the second support 105 and are all connected to the central shaft 102; the seventh connector 1057, the eighth connector 1058, and the ninth connector 1059 are disposed at the bottom of the second support 105 and are all connected to the bottom shaft 103.

[0173] The multiple gear connecting rods (106, 107, 108, 109) include a first gear connecting rod 106, a second gear connecting rod 107, a third gear connecting rod 108, and a fourth gear connecting rod 109. The first gear connecting rod 106 and the second gear connecting rod 107 are rotatably connected to both sides of the top shaft 101 of the main shaft 100, respectively, and the third gear connecting rod 108 and the fourth gear connecting rod 109 are rotatably connected to both sides of the bottom shaft 103 of the main shaft 100, respectively.

[0174] The structure of the main shaft 100 of the rotating shaft assembly 10 in this embodiment of the application will be described next with reference to the accompanying drawings. The main shaft 100 of the rotating shaft assembly 10 may also have other structures, which are not limited in this application. First, the structure of the top shaft 101 will be described.

[0175] Please refer to the following: Figures 8 to 10 , Figure 9 yes Figure 8 The diagram shown is an exploded view of the top shaft 101. Figure 10 yes Figure 9 The diagram shows the structural decomposition of the top axis 101 at another angle. Figure 10 Relative perspective Figure 9 The perspective is flipped left and right.

[0176] In some embodiments, the top shaft 101 may include a first main support plate 1011, a first mounting member 1012, and a second mounting member 1013. The first mounting member 1012 and the second mounting member 1013 are spaced apart, with the second mounting member 1013 located on the bottom side of the first mounting member 1012. The first mounting member 1012 and the second mounting member 1013 cover a portion of the structure of the first main support plate 1011, such that the remaining structure of the first main support plate 1011 is exposed relative to the first mounting member 1012 and the second mounting member 1013. Both the first mounting member 1012 and the second mounting member 1013 are located above the first main support plate 1011 and are fixedly connected to it. In this embodiment, the orientation with the same light emission direction as the screen 200 is defined as "down," and the orientation with the opposite light emission direction is defined as "up" (see [reference]). Figure 6 In some other embodiments, the top shaft 101 can also be obtained by an integrated molding process, that is, the first mounting part 1012 and the second mounting part 1013 and the first main support plate 1011 can be an integrated structure, which is not limited in this application.

[0177] Among them, such as Figure 9 As shown, the upper side of the first main support plate 1011 facing the first mounting member 1012 and the second mounting member 1013 may be provided with multiple mating structures and multiple notches (1011a, 1011b, 1011c, 1011d). The multiple mating structures are provided corresponding to the first mounting member 1012 and the second mounting member 1013, and are used to mate with the first mounting member 1012 and the second mounting member 1013 to form multiple top mounting spaces for mounting multiple connectors (1042, 1043) of the first support member 104 and multiple connectors (1052, 1053) of the second support member 105. The multiple mating structures may include openings, grooves, protrusions, etc. Multiple notches (1011a, 1011b, 1011c, 1011d) are exposed relative to the first mounting member 1012 and the second mounting member 1013 for mounting the first connector 1041 of the first support member 104 and the first connector 1051 of the second support member 105 or the gear connecting rod (106, 107).

[0178] For example, the multiple mating structures may include multiple arc surfaces (1014a, 1014b, 1014c, 1014d), which protrude upwards relative to the lower surface of the first main support plate 1011. The multiple arc surfaces (1014a, 1014b, 1014c, 1014d) include a first arc surface 1014a, a second arc surface 1014b, a third arc surface 1014c, and a fourth arc surface 1014d. The first arc surface 1014a and the second arc surface 1014b correspond to the first mounting member 1012 and are staggered. A limiting groove 1014e may be provided at one end of the first arc surface 1014a and the second arc surface 1014b near the middle of the first main support plate 1011. The third arc surface 1014c and the fourth arc surface 1014d correspond to the second mounting member 1013 and are arranged opposite each other. A limiting groove 1014f may be provided between the third arc surface 1014c and the fourth arc surface 1014d.

[0179] For example, the multiple notches (1011a, 1011b, 1011c, 1011d) may include a first notch 1011a, a second notch 1011b, a third notch 1011c, and a fourth notch 1011d. The first notch 1011a and the second notch 1011b are located at the top of the first main support plate 1011 and are symmetrically arranged. The first notch 1011a and the second notch 1011b correspond to the gap between the first mounting member 1012 and the protective assembly 19, that is, they are exposed relative to the first mounting member 1012, for installing the first connector 1041 of the first support member 104 and the first connector 1051 of the second support member 105. The third notch 1011c and the fourth notch 1011d are located at the bottom of the first main support plate 1011 and are symmetrically arranged. The third notch 1011c and the fourth notch 1011d correspond to the gap between the first mounting member 1012 and the second mounting member 1013, that is, they are exposed relative to the first mounting member 1012 and the second mounting member 1013, and are used to install the first gear connecting rod 106 and the second gear connecting rod 107.

[0180] The first main support plate 1011 may also be provided with a rotating connection protrusion 1011e. There may be two rotating connection protrusions 1011e, which are respectively provided on the top and bottom sides of the third notch 1011c and the fourth notch 1011d. The rotating connection protrusion 1011e may be provided with multiple rotating shaft grooves 1011f, and the opening of the rotating shaft grooves 1011f extends to the upper surface of the rotating connection protrusion 1011e.

[0181] The first main support plate 1011 may further include a limiting member 1015, a plurality of fastening holes 1016, and a plurality of limiting holes 1017. The limiting member 1015 is located in the central region of the first main support plate 1011. The central portion of the limiting member 1015 is recessed on both sides to form a limiting space for mounting the corresponding structure of the first mounting member 1012, thereby defining the mounting position of the first mounting member 1012 relative to the first main support plate 1011. The plurality of fastening holes 1016 penetrate the upper surface of the first main support plate 1011 and are distributed at the bottom, middle, and top of the first main support plate 1011, allowing fasteners to pass through. The limiting holes 1017 may be located near some of the fastening holes 1016, for cooperating with the limiting structures of the first mounting member 1012 or the second mounting member 1013 to define the mounting positions of the first mounting member 1012 and the second mounting member 1013 relative to the first main support plate 1011. The limiting hole 1017, together with the limiting member 1015, can jointly limit the installation position of the first mounting member 1012 and the second mounting member 1013 relative to the first main support plate 1011.

[0182] like Figure 10 As shown, by way of example, the first mounting member 1012 may be provided with multiple arc surfaces (1012a, 1012b, 1012c, 1012d) on the lower side facing the first main support plate 1011, and the multiple arc surfaces (1012a, 1012b, 1012c, 1012d) are recessed relative to the lower surface of the first mounting member 1012 for cooperating with a partial mating structure of the first main support plate 1011 to form multiple top mounting spaces for mounting multiple connectors (1042, 1043) of the first support member 104 and multiple connectors (1052, 1053) of the second support member 105.

[0183] The multiple curved surfaces (1012a, 1012b, 1012c, 1012d) include a fifth curved surface 1012a, a sixth curved surface 1012b, a seventh curved surface 1012c, and an eighth curved surface 1012d. The fifth curved surface 1012a and the sixth curved surface 1012b are located on the top of the first mounting member 1012, with the fifth curved surface 1012a corresponding to the first curved surface 1014a of the first main support plate 1011, and the sixth curved surface 1012b corresponding to the second curved surface 1014b of the first main support plate 1011. Both the fifth curved surface 1012a and the sixth curved surface 1012b may have limiting structures on their sides to limit the relative position of the structure mounted on the top shaft 101 and the top shaft 101. The seventh arc surface 1012c and the eighth arc surface 1012d are located at the bottom of the first mounting component 1012, and the seventh arc surface 1012c is set to correspond to the third arc surface 1014c of the first main support plate 1011, and the eighth arc surface 1012d is set to correspond to the fourth arc surface 1014d of the first main support plate 1011.

[0184] The first mounting member 1012 and the second mounting member 1013 may also be provided with rotatable connecting protrusions 1012e. There may be two rotatable connecting protrusions 1012e, each corresponding to a rotatable connecting protrusion 1011e on the first main support plate 1011. Each rotatable connecting protrusion 1012e may have multiple shaft grooves 1012f, the openings of which extend to the lower surface of the rotatable connecting protrusion 1012e. The shaft grooves 1012f of the first mounting member 1012 and the second mounting member 1013 can correspond to the shaft grooves 1011f of the first main support plate 1011 and combine to form shaft holes for mounting the shafts of the first gear connecting rod 106 and the second gear connecting rod 107.

[0185] The structure of the central axis 102 will be explained next.

[0186] The first mounting member 1012 and the second mounting member 1013 may also be provided with multiple fastening holes 1018 and limiting posts 1019, with the multiple fastening holes 1018 aligned with some of the fastening holes 1016 of the first main support plate 1011. This application allows fasteners to be inserted into the fastening holes 1018 of the first mounting member 1012 and the second mounting member 1013, and the fastening holes 1016 of the first main support plate 1011, to lock the first mounting member 1012 and the second mounting member 1013 to the first main support plate 1011. The limiting posts 1019 may be located near the fastening holes 1018 of the first mounting member 1012 and cooperate with the limiting holes 1017 of the first main support plate 1011 to limit the relative position of the first mounting member 1012 and the first main support plate 1011. For example, there may be multiple limiting posts 1019; by using multi-point limiting, the installation difficulty of the first mounting member 1012 is reduced, and assembly efficiency is improved. The limiting post 1019 can also be located near the fastening hole 1018 of the second mounting part 1013 and cooperate with the limiting hole 1017 of the first main support plate 1011 to reduce the installation difficulty of the second mounting part 1013.

[0187] Please refer to the following: Figure 8 , Figure 11 as well as Figure 12 , Figure 11 yes Figure 8 The diagram shown is an exploded view of the structure of the central axis 102. Figure 12 yes Figure 11 The diagram shows the structural decomposition of the central axis 102 at another angle. Figure 12 Relative perspective Figure 11 The perspective is flipped left and right.

[0188] In some embodiments, the central shaft 102 may include a second main support plate 1021 and a third mounting member 1022. The third mounting member 1022 is located above the second main support plate 1021 and near the top of the second main support plate 1021. The third mounting member 1022 covers a portion of the structure of the second main support plate 1021, so that the other structures of the second main support plate 1021 are exposed relative to the third mounting member 1022. The third mounting member 1022 is located above the second main support plate 1021 and is fixedly connected to the second main support plate 1021. In other embodiments, the central shaft 102 may also be obtained by an integrated molding process, that is, the third mounting member 1022 and the second main support plate 1021 may be an integrated structure, which is not limited in this application.

[0189] Among them, such as Figure 11 As shown, the upper side of the second main support plate 1021 facing the third mounting member 1022 may be provided with multiple mating structures and multiple notches (1021a, 1021b, 1021c, 1021d). The multiple notches (1021a, 1021b, 1021c, 1021d) are exposed relative to the third mounting member 1022, for mounting multiple connectors (1044, 1046) of the first support member 104 and multiple connectors (1054, 1056) of the second support member 105. The multiple mating structures may include openings, grooves, protrusions, etc., and are provided corresponding to the third mounting member 1022 for mating with the third mounting member 1022 to form a central mounting space for mounting the fifth connector 1045 of the first support member 104 and the fifth connector 1055 of the second support member 105.

[0190] For example, multiple mating structures may include a first arc surface 1023a and a second arc surface 1023b, both of which protrude relative to the lower surface of the second main support plate 1021. The first arc surface 1023a and the second arc surface 1023b correspond to the third mounting member 1022 and are staggered. A limiting groove 1023c may be provided at one end of the first arc surface 1023a and the second arc surface 1023b near the middle of the second main support plate 1021. Understandably, the implementation of the first arc surface 1023a and the second arc surface 1023b may be the same as or different from the first arc surface 1014a and the second arc surface 1014b of the first main support plate 1011 of the top shaft 101; this application does not limit this.

[0191] The multiple mating structures may further include multiple fastening holes 1024 and multiple limiting holes 1025. The multiple fastening holes 1024 penetrate the upper surface of the second main support plate 1021 and are distributed at the bottom, middle and top of the second main support plate 1021 to allow fasteners to pass through. The limiting holes 1017 may be located near the fastening holes 1024 and are used to mate with the limiting structure of the third mounting member 1022 to define the installation position of the third mounting member 1022 relative to the second main support plate 1021.

[0192] For example, the multiple notches (1021a, 1021b, 1021c, 1021d) may include a fifth notch 1021a, a sixth notch 1021b, a seventh notch 1021c, and an eighth notch 1021d. The fifth notch 1021a and the sixth notch 1021b are located at the top of the second main support plate 1021 and are symmetrically arranged. The fifth notch 1021a and the sixth notch 1021b are exposed relative to the third mounting member 1022 and are used to install the fourth connector 1044 of the first support member 104 and the fourth connector 1054 of the second support member 105. The seventh notch 1021c and the eighth notch 1021d are located at the bottom of the second main support plate 1021 and are symmetrically arranged. The seventh notch 1021c and the eighth notch 1021d are exposed relative to the third mounting member 1022 and are used to install the sixth connector 1046 of the first support member 104 and the sixth connector 1056 of the second support member 105.

[0193] like Figure 12 As shown, by way of example, the third mounting member 1022 may have a third arc surface 1022a and a fourth arc surface 1022b on the lower side facing the second main support plate 1021. The third arc surface 1022a and the fourth arc surface 1022b are recessed relative to the lower surface of the third mounting member 1022 to partially mate with the second main support plate 1021, thereby forming a central mounting space for mounting the fifth connector 1045 of the first support member 104 and the fifth connector 1055 of the second support member 105.

[0194] The third arc surface 1022a and the fourth arc surface 1022b are located in the middle of the third mounting member 1022, with the third arc surface 1022a corresponding to the first arc surface 1023a of the second main support plate 1021, and the fourth arc surface 1022b corresponding to the second arc surface 1023b of the second main support plate 1021. Both the third arc surface 1022a and the fourth arc surface 1022b may have limiting structures on their sides to limit the relative position of the structure mounted on the top shaft 101 with respect to the top shaft 101. Understandably, the implementation of the third arc surface 1022a and the fourth arc surface 1022b may be the same as or different from the fifth arc surface 1012a and the sixth arc surface 1012 of the first mounting member 1012 of the top shaft 101; this application does not limit this.

[0195] For example, the third mounting member 1022 may also be provided with multiple fastening holes 1026 and limiting posts 1027, with the multiple fastening holes 1026 of the third mounting member 1022 aligned with some of the fastening holes 1024 of the second main support plate 1021. This application can lock the third mounting member 1022 to the second main support plate 1021 by inserting fasteners into the fastening holes 1026 of the third mounting member 1022 and the fastening holes 1024 of the second main support plate 1021. The limiting posts 1027 may be located near the fastening holes 1026 of the third mounting member 1022 and cooperate with the limiting holes 1025 of the second main support plate 1021 to limit the relative position of the third mounting member 1022 and the second main support plate 1021. For example, the number of limiting posts 1027 can be multiple, reducing the installation difficulty of the third mounting member 1022 and improving assembly efficiency through multi-point limiting.

[0196] For example, the structure of the bottom shaft 103 can be designed with reference to the top shaft 101, and it is provided with a bottom mounting space for mounting the third gear connecting rod 108, the fourth gear connecting rod 109, and the bottom connecting assembly, which will not be described in detail here. In some other embodiments, part or all of the structure of the bottom shaft 103 may also be different from that of the top shaft 101, and can be designed according to actual needs. This application does not limit this. It should be understood that in the embodiments of this application, when one component is designed with reference to another component, the structures of the two components may be completely identical, or the core structures of the two components may be the same, and a few structural differences may exist. This application does not strictly limit this.

[0197] Please refer to the following: Figure 9 , Figure 10 as well as Figure 13 , Figure 13 yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 cut along line A1-A1. The cross-section along line A1-A1 passes through the first main support plate 1011 of the top shaft 101.

[0198] In some embodiments, the first notch 1011a and the second notch 1011b of the first main support plate 1011 of the top shaft 101 are respectively located near both sides of the main shaft 100 of the rotating shaft assembly 10 and communicate with the space outside the main shaft 100 of the rotating shaft assembly 10. A first connecting rib 1011g is provided between the first notch 1011a and the second notch 1011b. The first connecting rib 1011g has a first step surface 1011m and a second step surface 1011n on the side facing the first notch 1011a. The first step surface 1011m faces the upper surface of the first main support plate 1011 and is parallel to the upper surface of the first main support plate 1011, and the second step surface 1011n faces the first notch 1011a and has an angle with the first step surface 1011m to limit the rotation angle of the structure installed in the first notch 1011a relative to the main shaft 100 of the rotating shaft assembly 10. The first connecting rib 1011g has a third stepped surface 1011o and a fourth stepped surface 1011p on the side facing the second notch 1011b. The third stepped surface 1011o faces the upper surface of the first main support plate 1011 and is parallel to the upper surface of the first main support plate 1011. The fourth stepped surface 1011p faces the second notch 1011b and has an angle with the third stepped surface 1011o, so as to limit the rotation angle of the structure installed in the second notch 1011b relative to the main shaft 100 of the rotating shaft assembly 10.

[0199] For example, the first step surface 1011m and / or the third step surface 1011o may also have an angle with the upper surface of the first main support plate 1011, that is, they are not parallel to the upper surface of the first main support plate 1011. This application does not limit this.

[0200] Please refer to the following: Figure 9 , Figure 10 , Figure 14A and Figure 14B , Figure 14A yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 cut along line A2-A2. Figure 14B yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 cut along A3-A3. Both the cross-sections along A2-A2 and A3-A3 pass through the first main support plate 1011 and the first mounting component 1012.

[0201] In some embodiments, the first arc surface 1014a of the first main support plate 1011 is disposed opposite to the fifth arc surface 1012a of the first mounting member 1012, and is formed between the corresponding first arc surface 1014a and the fifth arc surface 1012a. The first arc-shaped space 10101 is part of the top mounting space of the main shaft 100 of the rotating shaft assembly 10, and is used for mounting a portion of the structure of the second connector 1042 of the first support member 104. The second arc surface 1014b of the first main support plate 1011 is disposed opposite to the sixth arc surface 1012b of the first mounting member 1012, and a second arc-shaped space 10102 is formed between the corresponding second arc surface 1014b and the sixth arc surface 1012b. The second arc-shaped space 10102 is part of the space of the top shaft 101, and is used for mounting a portion of the structure of the second connector 1052 of the second support member 105.

[0202] Please refer to the following: Figure 9 , Figure 10 as well as Figure 15 , Figure 15 yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 taken along line A4-A4. The section along line A4-A4 passes through the first main support plate 1011 and the first mounting member 1012. For example, the first mounting member 1012 engages with the limiting space of the limiting member 1015 of the first main support plate 1011 to define the installation position of the first mounting member 1012 relative to the first main support plate 1011. The cross-sectional shape of the first mounting member 1012 conforms to the cross-sectional shape of the limiting space to better define the installation position, reduce installation difficulty, and improve assembly accuracy.

[0203] Please refer to the following: Figure 9 , Figure 10 as well as Figure 16 , Figure 16 yes Figure 8The diagram shows a cross-sectional view of the top shaft 101 cut along line A5-A5. The section along line A5-A5 passes through the first main support plate 1011 and the first mounting member 1012. For example, the third arc surface 1014c of the first main support plate 1011 is positioned opposite to the seventh arc surface 1012c of the first mounting member 1012, forming a third arc-shaped space 10103 between the corresponding third arc surface 1014c and the seventh arc surface 1012c; the fourth arc surface 1014d of the first main support plate 1011 is positioned opposite to the eighth arc surface 1012d of the first mounting member 1012, forming a fourth arc-shaped space 10104 between the corresponding fourth arc surface 1014d and the eighth arc surface 1012d. The third arc-shaped space 10103 and the fourth arc-shaped space 10104 are part of the top mounting space of the main shaft 100 of the rotating shaft assembly 10, and are used to install the third connector 1043 of the first support 104 and the third connector 1053 of the second support 105, respectively.

[0204] Please refer to the following: Figure 9 , Figure 10 as well as Figure 17 , Figure 17 yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 cut along line A6-A6. The cross-section along line A6-A6 passes through the first main support plate 1011. For example, the rotatable connecting protrusion 1011e of the first main support plate 1011 is opposite to the rotatable connecting protrusion 1012e of the first mounting member 1012. The shaft groove 1011f of the rotatable connecting protrusion 1011e corresponds to the shaft groove 1012f of the rotatable connecting protrusion 1012e and forms a shaft hole. The shaft hole connects to the third notch 1011c and the fourth notch 1011d. The third notch 1011c and the fourth notch 1011d are part of the top mounting space of the main shaft 100 of the shaft assembly 10, and can respectively connect to the space outside the shaft assembly 10.

[0205] Please refer to the following: Figure 11 , Figure 12 as well as Figure 18 , Figure 18 yes Figure 8 The diagram shows a cross-sectional view of the central axis 102 cut along line A7-A7. The cross-section along line A7-A7 passes through the second main support plate 1021.

[0206] In some embodiments, the fifth notch 1021a and the sixth notch 1021b of the second main support plate 1021 of the central shaft 102 are respectively located near both sides of the main shaft 100 of the rotating shaft assembly 10 and communicate with the space outside the main shaft 100 of the rotating shaft assembly 10. A second connecting rib 1021e is provided between the fifth notch 1021a and the sixth notch 1021b. The second connecting rib 1021e has a first step surface 1021m and a second step surface 1021n on the side facing the fifth notch 1021a. The first step surface 1021m faces the upper surface of the second main support plate 1021, and the second step surface 1021n faces the fifth notch 1021a and has an angle with the first step surface 1021m to limit the rotation angle of the structure installed on the fifth notch 1021a relative to the main shaft 100 of the rotating shaft assembly 10. The second connecting rib 1021e has a third stepped surface 1021o and a fourth stepped surface 1021p on the side facing the sixth notch 1021b. The third stepped surface 1021o faces the upper surface of the second main support plate 1021, and the fourth stepped surface 1021p faces the sixth notch 1021b and has an angle with the third stepped surface 1021o to limit the rotation angle of the structure installed in the sixth notch 1021b relative to the main shaft 100 of the rotating shaft assembly 10.

[0207] The first step surface 1021m and / or the third step surface 1021o may be parallel to the upper surface of the second main support plate 1021, or they may have an angle with the upper surface of the second main support plate 1021, that is, they may not be parallel to the upper surface of the second main support plate 1021. This application does not limit this.

[0208] For example, the central mounting space formed between the second main support plate 1021 of the central shaft 102 and the third mounting member 1022 can refer to the first arc-shaped space 10101 and the second arc-shaped space 10102 formed between the first main support plate 1011 and the first mounting member 1012 of the top shaft 101, which will not be described in detail here.

[0209] For example, the seventh notch 1021c and the eighth notch 1021d of the second main support plate 1021 of the central shaft 102 are respectively located close to the two sides of the main shaft 100 of the rotating shaft assembly 10, and the connection relationship between the two can be referred to the fifth notch 1021a and the sixth notch 1021b, which will not be described again here.

[0210] The following description, in conjunction with the accompanying drawings, will illustrate the structure of the plurality of support members (104, 105) and the plurality of gear connecting rods (106, 107, 108, 109) connected to the spindle 10 of the shaft assembly 10 in the embodiments of this application. The above-mentioned components may also have other structures, which are not limited in this application.

[0211] Please refer to the following: Figure 8 and Figure 19 , Figure 19 yes Figure 8 A partial structural schematic diagram of the first support member 104 shown.

[0212] In the top connecting assembly of the first support member 104, the first connector 1041 is provided with a limiting member to cooperate with the limiting structure of the top shaft 101. The second connector 1042 and the third connector 1043 are both provided with rotating arms to rotatably connect to the top shaft 101. In the middle connecting assembly of the first support member 104, the fourth connector 1044 and the sixth connector 1046 are both provided with limiting members to cooperate with the limiting structure of the central shaft 102. The fifth connector 1045 is provided with a rotating arm to rotatably connect to the central shaft 102.

[0213] For example, the multiple connectors of the first support member 104 each include a proximal portion and a distal portion. The proximal portion is the part of the connector closer to the main shaft 100 of the rotating shaft assembly 10, and the distal portion is the part of the connector farther from the main shaft 100 of the rotating shaft assembly 10. The structures of the proximal and distal portions can be identical and mirror-symmetrical. Alternatively, the structures of the proximal and distal portions can be different. Furthermore, the proximal and distal portions can be arranged opposite to each other or staggered; the proximal and distal portions can be directly fixedly connected, fixedly connected by fasteners, or have a gap. This application does not specifically limit the above features.

[0214] The first connector 1041, the second connector 1042, the third connector 1043, and the fourth connector 1044 each include a proximal portion (1041b, 1042b, 1043b, 1044b) and a distal portion (1041a, 1042a, 1043a, 1044a). For example, the proximal portion 1041b of the first connector 1041 is opposite to and fixedly connected to the distal portion 1041a; the proximal portion 1042b of the second connector 1042 is offset from and fixedly connected to the distal portion 1042a by a fastener; the proximal portion 1043b of the third connector 1043 is opposite to and fixedly connected to the distal portion 1043a by a fastener; and the proximal portion 1044b of the fourth connector 1044 is opposite to the distal portion 1044a, with a groove 1044c between them.

[0215] The structure of the fifth connector 1045 can be referenced from that of the second connector 1042, and will not be described again here. Understandably, the structure of the fifth connector 1045 may be the same as or different from that of the second connector 1042. Furthermore, the structure of the sixth connector 1046 can be referenced from that of the fourth connector 1044, and will not be described again here. Understandably, the structure of the sixth connector 1046 may be the same as or different from that of the fourth connector 1044, and this application does not impose any limitations on this.

[0216] The structure of the multiple connectors (1047, 1048, 1049) of the bottom connecting assembly of the first support member 104 can be referenced to the multiple connectors (1041, 1042, 1043) of the top connecting assembly of the first support member 104, and will not be described again here.

[0217] The structure of the second support member 105 can be referenced from that of the first support member 104, and will not be described again here. The structure of the second support member 105 can be the same as that of the first support member 104, so as to use the same material, thereby saving the types of materials for the rotating shaft assembly 10 and reducing the cost of the rotating shaft assembly 10. The structure of the second support member 105 can be different from that of the first support member 104, and this application does not impose any restrictions on this.

[0218] Please refer to the following: Figure 8 , Figure 20A and Figure 20B , Figure 20A yes Figure 8 The diagram shown is a structural schematic of the first gear connecting rod 106. Figure 20B yes Figure 8 The diagram shows the structure of the second gear connecting rod 107. In some embodiments, the first gear connecting rod 106 includes a rotating end 1061 and a sliding end 1062 disposed opposite to each other. The rotating end 1061 of the first gear connecting rod 106 is rotatably connected to the main shaft 100, and the sliding end 1062 of the first gear connecting rod 106 is slidably connected to the first fixing member 15. The rotating end 1061 of the first gear connecting rod 106 is provided with a rotating shaft 1061a and a plurality of meshing teeth 1061b, which are arranged around the rotating shaft 1061a. The sliding end 1062 of the first gear connecting rod 106 includes a sliding block 1062a. The second gear connecting rod 107 includes a rotating end 1071 and a sliding end 1072. The rotating end 1071 of the second gear connecting rod 107 is rotatably connected to the main shaft 100, and the sliding end 1072 of the second gear connecting rod 107 is slidably connected to the second fixing member 16. The rotating end 1071 of the second gear connecting rod 107 is provided with a rotating shaft 1071a and multiple meshing teeth 1071b, which are arranged around the rotating shaft 1071a. The sliding end 1072 of the second gear connecting rod 107 includes a sliding block 1072a.

[0219] Please refer to the following: Figure 3 , Figure 4 and Figure 21 , Figure 21 yes Figure 8 The diagram shows the assembly structure of the first support member 104, the second support member 105, the first gear connecting rod 106, the second gear connecting rod 107, the top shaft 101, and the central shaft 102.

[0220] In some embodiments, the first support member 104 and the second support member 105 are rotatably connected to both sides of the main shaft 100, that is, the first support member 104 is rotatably connected to one side of the main shaft 100, and the second support member 105 is rotatably connected to the other side of the main shaft 100. The first support member 104, the second support member 105, and the side of the main shaft 100 facing the screen 200 form a support surface 4. The surface of the main shaft 100 facing the screen 200 is a plane 42, the surface of the first support member 104 facing the screen 200 is a curved surface 41, and the surface of the second support member 105 facing the screen 200 is a curved surface 43. Figure 3 As shown, when the electronic device 1000 is in the open state, the first support 104 and the second support 105 can be flattened relative to the main shaft 100, so that the curved surfaces 41 and 43 are flattened relative to the plane 42, providing a flat support environment. Figure 4 As shown, when the electronic device 1000 is in a closed state, the first support member 104 and the second support member 105 can be folded relative to the main shaft 100 so that the curved surface 41 and the curved surface 43 are tilted relative to the plane 42, forming an arc-shaped support surface 4, which provides support for the middle part of the screen 200, so that the middle part of the screen 200 presents a natural curvature, avoids creases on the screen 200, ensures the display effect and touch sensing effect of the screen 200, reduces the risk of damage to the screen 200, and extends the service life of the screen 200.

[0221] Figure 21 Please refer to the following: Figure 21 , Figure 22A and Figure 22B , Figure 22A yes Figure 21 The schematic diagram shows the cross-sectional structure of the rotating shaft assembly 10 cut along line B1-B1. Figure 22B yes Figure 22A The diagram shows the structure in its closed state. Figure 21 The position of B1-B1 in the middle corresponds to Figure 8 The position of A1-A1. The cross section cut along A1-A1 passes through the first connector 1041 of the first support member 104, the first connector 1051 of the second support member 105, and the first main support plate 1011 of the top shaft 101.

[0222] In some embodiments, the first connector 1041 of the first support member 104 and the first connector 1051 of the second support member 105 are respectively connected to both sides of the top shaft 101. The proximal portion 1041b of the first connector 1041 is installed in the first notch 1011a of the top shaft 101, and the proximal portion 1051b of the first connector 1051 is installed in the second notch 1011b of the top shaft 101.

[0223] For example, both the lower ends of the proximal portions 1041b and 1051b of the first connector 1041 and the first connector 1051 are provided with notches, the shape of which conforms to the shape of the side steps of the first connecting rib 1011g. In the open state, there is a gap between the first support 104 and the second support 105 and the top shaft 101; in the closed state, the first support 104 and the second support 105 are close to each other relative to the top shaft 101, and the inner walls of the notches at the lower ends of the proximal portions 1041b and 1051b of the first connector 1041 and the first connector 1051 are fitted with the step surfaces on both sides of the first connecting rib 1011g.

[0224] Wherein, there is an included angle between the first step surface 1011m and the second step surface 1011n of the first connecting rib 1011g, and the inner wall of the notch at the lower end of the near-axial portion 1041b of the first connecting member 1041 fits against the first step surface 1011m and the second step surface 1011n of the first connecting rib 1011g, so that the first support member 104 is inclined relative to the top shaft 101 in the closed state; there is an included angle between the third step surface 1011o and the fourth step surface 1011p of the first connecting rib 1011g, and the first connecting member 1051... The inner wall of the notch at the lower end of the near-axial portion 1051b is fitted with the third step surface 1011o and the fourth step surface 1011p of the first connecting rib 1011g, so that the second support member 105 is tilted relative to the central axis 102 in the closed state. This allows the lower surface of the first support member 104 and the lower surface of the second support member 105 to be tilted relative to the lower surface of the main shaft 100 of the rotating shaft assembly 10 in the closed state. That is, the curved surfaces (41, 43) of the folding assembly 1 can be tilted relative to the plane 42, together forming an arc-shaped support surface 4 (see reference). Figure 4 ), providing support for the center of screen 200.

[0225] Please refer to the following: Figure 21 , Figure 23A and Figure 23B , Figure 23A yes Figure 21 The diagram shows a cross-sectional view of the rotating shaft assembly 10 taken along line B2-B2. Figure 23B yes Figure 23A The diagram shows the structure in its closed state. Figure 21 The position of B2-B2 corresponds to Figure 8 The position of A2-A2. The section cut along B2-B2 passes through the second connector 1042 of the first support member 104, the second connector 1052 of the second support member 105, the first mounting member 1012 of the top shaft 101, and the first main support plate 1011 of the top shaft 101.

[0226] In some embodiments, the second connector 1042 of the first support member 104 is rotatably connected to the top shaft 101. Specifically, a portion of the proximal portion 1042b of the second connector 1042 is mounted in the first arcuate space 10101 of the top shaft 101, thus rotatably connecting to the top shaft 101 via a virtual axis connection. Furthermore, as the first support member 104 rotates relative to the top shaft 101, the proximal portion 1042b of the second connector 1042 moves along the first arcuate space 10101 towards the top shaft 101.

[0227] In some other embodiments, the near-axial portion 1042b of the second connector 1042 may also be rotatably connected to the top shaft 101 via a solid shaft connection, and this application does not impose strict limitations on this.

[0228] Please refer to the following: Figure 21 , Figure 24A and Figure 24B , Figure 24A yes Figure 21 The diagram shows a cross-sectional view of the rotating shaft assembly 10 taken along line B3-B3. Figure 24B yes Figure 24A The diagram shows the structure in its closed state. Figure 21 The position of B3-B3 corresponds to Figure 8 The section cut along B3-B3 passes through the second connector 1042 of the first support member 104, the second connector 1052 of the second support member 105, the first mounting member 1012 of the top shaft 101, and the first main support plate 1011 of the top shaft 101.

[0229] In some embodiments, the second connector 1052 of the second support member 105 is rotatably connected to the top shaft 101. Specifically, a portion of the proximal portion 1052b of the second connector 1052 is mounted to the second arcuate space 10102 of the top shaft 101, thus rotatably connecting to the top shaft 101 via a virtual axis connection. Furthermore, as the second support member 105 rotates relative to the top shaft 101, the proximal portion 1052b of the second connector 1052 moves along the second arcuate space 10102 towards the top shaft 101.

[0230] In some other embodiments, the near-axial portion 1052b of the second connector 1052 may also be rotatably connected to the top shaft 101 via a solid shaft connection, and this application does not impose strict limitations on this.

[0231] Please refer to the following: Figures 23A to 24BThe second connector 1042 of the first support member 104 is rotatably connected to the main shaft 100 of the rotating shaft assembly 10, and the second connector 1052 of the second support member 105 is rotatably connected to the main shaft 100 of the rotating shaft assembly 10, so that the first support member 104 and the second support member 105 can unfold and fold relative to the main shaft 100 of the rotating shaft assembly 10. The second arc-shaped space 10102 and the first arc-shaped space 10101 are staggered to avoid interference between the second connector 1042 of the first support member 104 and the second connector 1052 of the second support member 105 during rotation relative to the main shaft 100 of the rotating shaft assembly 10, thus ensuring smooth and stable movement of the connectors relative to the main shaft 100.

[0232] Please refer to the following: Figure 21 , Figure 25A and Figure 25B , Figure 25A yes Figure 21 The diagram shows a cross-sectional view of the rotating shaft assembly 10 taken along line B4-B4. Figure 25B yes Figure 25A The diagram shows the structure in its closed state. Figure 21 The position of B4-B4 corresponds to Figure 8 The section cut along B4-B4 passes through the third connector 1043 of the first support member 104, the third connector 1053 of the second support member 105, the first mounting member 1012 of the top shaft 101, and the first main support plate 1011 of the top shaft 101.

[0233] In some embodiments, the third connector 1043 of the first support member 104 and the third connector 1053 of the second support member 105 are rotatably connected to the main shaft 100 of the rotating shaft assembly 10. Specifically, a portion of the proximal portion 1043b of the third connector 1043 of the first support member 104 is mounted in the third arcuate space 10103 of the top shaft 101, rotatably connecting the top shaft 101 via a virtual shaft connection. Conversely, a portion of the proximal portion 1053b of the third connector 1053 of the second support member 105 is mounted in the fourth arcuate space 10104 of the top shaft 101, rotatably connecting the top shaft 101 via a virtual shaft connection. In this application, the proximal portion 1043b of the third connector 1043 is movable along the third arcuate space 10103, and the proximal portion 1053b of the third connector 1053 is movable along the fourth arcuate space 10104, so that the first support 104 and the second support 105 unfold and close relative to the main shaft 100 of the rotating shaft assembly 10, thereby deforming the rotating shaft assembly 10. In some other embodiments, the proximal portions 1043b of the third connector 1043 and / or the proximal portions 1053b of the third connector 1053 can also be rotatably connected to the top shaft 101 via a solid shaft connection, which is not strictly limited in this application.

[0234] Please refer to the following: Figure 21 , Figure 26A and Figure 26B , Figure 26A yes Figure 21 The schematic diagram shows a cross-sectional view of the rotating shaft assembly 10 taken along line B5-B5. Figure 26B yes Figure 26A The diagram shows the structure in its closed state. Figure 21 The position of B5-B5 corresponds to Figure 8 The position is A6-A6. The section cut along B5-B5 passes through the first gear connecting rod 106, the second gear connecting rod 107, and the first main support plate 1011 of the top shaft 101.

[0235] In some embodiments, the rotating end 1061 of the first gear connecting rod 106 is mounted on the third notch 1011c of the first main support plate 1011 of the top shaft 101, and the rotating shaft 1061a of the rotating end 1061 is engaged in the rotating shaft hole of the top shaft 101 of the rotating shaft assembly 10, so that the rotating end 1061 of the first gear connecting rod 106 is rotatably connected to the top shaft 101 of the rotating shaft assembly 10.

[0236] The rotating end 1071 of the second gear connecting rod 107 is installed in the fourth notch 1011d of the first main support plate 1011 of the top shaft 101, and the rotating shaft 1071a of the rotating end 1071 is inserted into the rotating shaft hole of the top shaft 101 of the rotating shaft assembly 10, so that the rotating end 1071 of the second gear connecting rod 107 is rotatably connected to the main shaft 100 of the rotating shaft assembly 10.

[0237] Furthermore, multiple meshing teeth 1061b of the rotating end 1061 of the first gear connecting rod 106 mesh with multiple meshing teeth 1071b of the rotating end 1071 of the second gear connecting rod 107. That is, the rotating end 1061 of the first gear connecting rod 106 meshes with the rotating end 1071 of the second gear connecting rod 107. Therefore, the rotation angle of the rotating end 1061 of the first gear connecting rod 106 is the same in magnitude and opposite in direction to the rotation angle of the rotating end 1071 of the second gear connecting rod 107. This makes the rotation of the first gear connecting rod 106 and the second gear connecting rod 107 relative to the main shaft 100 of the rotating shaft assembly 10 synchronized, that is, synchronously approaching or moving away from each other.

[0238] Please refer to the following: Figure 21 , Figure 27A and Figure 27B , Figure 27A yes Figure 21 The diagram shows a cross-sectional view of the rotating shaft assembly 10 taken along line B6-B6. Figure 27B yes Figure 27A The diagram shows the structure in its closed state.Figure 21 The position of B6-B6 corresponds to Figure 8 The position is A7-A7. The section cut along B6-B6 passes through the first support member 104, the second support member 105, and the second main support plate 1021 of the central axis 102.

[0239] In some embodiments, the fourth connector 1044 of the first support member 104 and the fourth connector 1054 of the second support member 105 are respectively connected to both sides of the central shaft 102. The proximal portion 1044b of the fourth connector 1044 is installed in the fifth notch 1021a of the central shaft 102, and the proximal portion 1054b of the fourth connector 1054 is installed in the sixth notch 1021b of the central shaft 102.

[0240] For example, both the lower ends of the proximal portions 1044b and 1054b of the fourth connector 1044 and the fourth connector 1054 are provided with notches, the shape of which conforms to the shape of the side steps of the second connecting rib 1021e. In the open state, there is a gap between the first support 104 and the second support 105 and the central shaft 102; in the closed state, the first support 104 and the second support 105 are close to each other relative to the central shaft 102, and the inner walls of the notches at the lower ends of the proximal portions 1044b and 1054b of the fourth connector 1044 and the fourth connector 1054 conform to the step surfaces on both sides of the second connecting rib 1021e.

[0241] In this configuration, an angle exists between the first step surface 1021m and the second step surface 1021n of the second connecting rib 1021e. The inner wall of the notch at the lower end of the near-axial portion 1044b of the fourth connecting member 1044 fits against the first step surface 1021m and the second step surface 1021n of the second connecting rib 1021e, so that the first support member 104 is inclined relative to the central axis 102. An angle exists between the third step surface 1021o and the fourth step surface 1021p of the second connecting rib 1021e. The inner wall of the notch at the lower end of the near-axial portion 1054b of the fourth connecting member 1054 fits against the third step surface 1021o and the fourth step surface 1021p of the second connecting rib 1021e, so that the second support member 105 is inclined relative to the central axis 102. That is, the curved surfaces (41, 43) of the folding assembly 1 can be inclined relative to the plane 42, forming an arc-shaped support surface 4 (see reference). Figure 4 ), providing support for the center of screen 200.

[0242] Specifically, the groove between the proximal portion 1044b and the distal portion 1044a of the fourth connector 1044 mates with the structure of the main shaft 100 of the rotating shaft assembly 10, and the groove between the proximal portion 1054b and the distal portion 1054a of the fourth connector 1054 mates with the structure of the main shaft 100 of the rotating shaft assembly 10, so that the first support member 104 and the second support member 105 are tightly connected to the main shaft 100 of the rotating shaft assembly 10. Therefore, the overall structure of the rotating shaft assembly 10, consisting of the main shaft 100 of the rotating shaft assembly 10, the first support member 104, and the second support member 105, is complete and has good stability.

[0243] For example, the connection structure between the fifth connector 1045 of the first support member 104 and the fifth connector 1055 of the second support member 105 and the central shaft 102 can be referred to the connection structure between the first connector 1041 of the first support member 104 and the first connector 1051 of the second support member 105 and the top shaft 101, which will not be described again here.

[0244] For example, the connection structure between the sixth connector 1046 of the first support member 104 and the sixth connector 1056 of the second support member 105 and the central shaft 102 can be referred to the connection structure between the fourth connector 1044 of the first support member 104 and the fourth connector 1054 of the second support member 105 and the central shaft 102, and will not be described again here.

[0245] For example, the connection structure between the bottom connecting components (1047, 1048, 1049) of the first support member 104 and the bottom connecting components (1057, 1058, 1059) of the second support member 105 and the bottom shaft 103 can be referenced to the connection structure between the top connecting components (1041, 1042, 1043) of the first support member 104 and the top connecting components (1051, 1052, 1053) of the second support member 105 and the top shaft 101, and will not be described again here.

[0246] Please refer to the following: Figure 8 , Figures 22A to 25B , Figure 27A and Figure 27B .like Figure 8 and Figures 23A to 25B As shown, in this application, the rotating connectors (1042, 1043, 1045, 1047, 1048) of the first support member 104 are rotatably connected to the main shaft 100 of the rotating shaft assembly 10, and the rotating connectors (1052, 1053, 1055, 1057, 1058) of the second support member 105 are rotatably connected to the main shaft 100 of the rotating shaft assembly 10, so that the first support member 104 and the second support member 105 unfold and fold relative to the main shaft 100 of the rotating shaft assembly 10, thereby causing the rotating shaft assembly 10 to deform. Furthermore, as... Figure 8 , Figure 22A , Figure 22B , Figure 27A and Figure 27B As shown, the mating connectors (1041, 1044, 1046, 1049) of the first support member 104 and the mating connectors (1051, 1054, 1056, 1059) of the second support member 105 mate with the notches of the main shaft 100 of the hinge assembly 10. Therefore, the overall structure of the hinge assembly 10, consisting of the main shaft 100 of the hinge assembly 10, the first support member 104, and the second support member 105, is complete and has good stability, thus providing a stable support environment for the screen 200 and ensuring the display performance and touch control performance of the screen 200.

[0247] The following description, in conjunction with the accompanying drawings, illustrates the implementation of the structure of the first fixing member 15, the structure of the second fixing member 16, and the connection structure between the first fixing member 15, the second fixing member 16, and the rotating shaft assembly 10 in this embodiment of the application. Other structures may also exist, and this application does not limit them.

[0248] Please refer to the following: Figure 7 and Figure 28 , Figure 28 yes Figure 7 The exploded structural diagram of the first fastener 15 shown.

[0249] In some embodiments, the first fixing member 15 may include a first main fixing plate 150 and a plurality of fixing connectors (151, 152, 153, 154, 155). The plurality of fixing connectors (151, 152, 153, 154, 155) include a first fixing connector 151, a second fixing connector 152, a third fixing connector 153, a fourth fixing connector 154, and a fifth fixing connector 155, and are sequentially and spaced apart from the first main fixing plate 150. The plurality of fixing connectors (151, 152, 153, 154, 155) are used to connect to the first support member 104 of the rotating shaft assembly 10 and are deformable to drive the first fixing member 15 to move relative to the rotating shaft assembly 10.

[0250] The first fixing connector 151 and the second fixing connector 152 are located at the top of the first main fixing plate 150 and are used to connect some of the top connectors (1042, 1043) of the first support member 104. The third fixing connector 153 is located in the middle of the first main fixing plate 150 and is used to connect the fifth connector 1045 in the middle of the first support member 104. The fourth fixing connector 154 and the fifth fixing connector 155 are located at the bottom of the first main fixing plate 150 and are used to connect some of the bottom connectors (1047, 1048) of the first support member 104. The structure of the third fixing connector 153 and the fifth fixing connector 155 is the same as that of the first fixing connector 151; the structure of the fourth fixing connector 154 and the second fixing connector 152 is the same, so as to use the same material, save the types of materials of the first support member 104, and reduce the cost of the first support member 104. The structure of the third fixing member 153 and / or the fifth fixing member 155 may also be different from that of the first fixing member 151, and / or the structure of the fourth fixing member 154 and the second fixing member 152 may be different. This application does not limit this.

[0251] For example, the first main fixing plate 150 of the first fixing member 15 may also be provided with multiple connecting structures. The connecting structures may include openings, grooves, protrusions and other structures to cooperate with the structure of the rotating shaft assembly 10 and limit the angle of rotation of the first fixing member 15 relative to the rotating shaft assembly 10.

[0252] The first main fixing plate 150 may have a connection notch 1501 at its top, located on the side of the first main fixing plate 150 near the rotating shaft assembly 10. The connection notch 1501 serves as an installation space for the first connector 1041 of the first support member 104. Correspondingly, the first main fixing plate 150 may also have a notch at its bottom, serving as an installation space for the ninth connector 1049 of the first support member 104.

[0253] For example, the middle portion of the first main fixing plate 150 may be provided with a plurality of connecting blocks 1505 spaced apart. The plurality of connecting blocks 1505 protrude relative to the upper surface of the first main fixing plate 150 and are respectively used to structurally cooperate with the middle connecting members (1044, 1046) of the first support member 104. It is understood that the structures of the plurality of connecting blocks 1505 may be the same, or at least one connecting block 1505 may have a different structure from the other connecting blocks 1505. The structure of the connecting blocks 1505 may be designed according to the structure of the middle connecting members (1044, 1046) of the first support member 104, and this application does not limit this.

[0254] For example, the first main fixing plate 150 may also be provided with a plurality of first sliding grooves 1506. The plurality of first sliding grooves 1506 are distributed at the top and bottom of the first main fixing plate 150. Each first sliding groove 1506 has two opposing upper sidewalls 1506a and lower sidewalls 1506b, which are recessed to jointly form a guide space for the first sliding groove 1506. That is, the sidewalls of the first sliding groove 1506 may have recessed guide spaces to guide the sliding direction of the structural members installed in the first sliding groove 1506, making the relative sliding action between the first fixing member 15 and the corresponding structural member easier to achieve and providing higher control precision.

[0255] For example, the first main fixing plate 150 may also be provided with a plurality of mounting notches 1502, a plurality of fastening holes 1503, and a plurality of limiting holes 1504, all of which penetrate the upper surface of the first main fixing plate 150. The plurality of mounting notches 1502 are located on the side of the first main fixing plate 150 near the rotating shaft assembly 10 and are spaced apart, serving as mounting spaces for a plurality of fixing connectors (151, 152, 153, 154, 155). The plurality of fastening holes 1503 are distributed at the bottom, middle, and top of the first main fixing plate 150, allowing fasteners to pass through. The limiting holes 1504 are located near the fastening holes 1503 and are used to cooperate with the limiting structures of the plurality of fixing connectors (151, 152, 153, 154, 155).

[0256] Please refer to the following: Figure 28 and Figure 29 , Figure 29 yes Figure 28 A structural schematic diagram of the first fixed connector 151 from another angle.

[0257] In some embodiments, the first fixed connector 151 may include a rotatable connecting end 151a and a fixed end 151b. The fixed end 151b is the end of the first fixed connector 151 near the first main fixing plate 150, used for fixed connection with the first main fixing plate 150; the rotatable connecting end 151a is the other end of the first fixed connector 151 away from the first main fixing plate 150, used for connecting the first support member 104. The rotatable connecting end 151a is provided with an arc-shaped groove 1510, which serves as an installation space for part of the connector of the first support member 104.

[0258] The fixed end 151b may be provided with multiple fastening holes 1511 and multiple limiting posts 1512. The multiple fastening holes 1511 of the first fixed connector 151 are aligned with some of the fastening holes 1503 of the first main fixing plate 150. This application allows fasteners to be inserted into the fastening holes 1511 of the first fixed connector 151 and the fastening holes 1503 of the first main fixing plate 150 to lock the first fixed connector 151 to the first main fixing plate 150. The multiple limiting posts 1512 are located on the lower surface of the first fixed connector 151 facing the first main fixing plate 150 and are used to cooperate with the limiting holes 1504 of the first main fixing plate 150 to limit the installation position of the first fixed connector 151 relative to the first main fixing plate 150.

[0259] For example, the structures of the third fixing member 153 and the fifth fixing member 155 can be referenced to the first fixing member 151, and will not be described again here. It is understood that the structures of the third fixing member 153 and / or the fifth fixing member 155 may be the same as or different from the first fixing member 151, and this application does not limit them in this regard.

[0261] In some embodiments, the second fixed connector 152 may include a rotatable connecting end 152a and a fixed end 152b. The fixed end 152b is the end of the second fixed connector 152 closer to the first main fixing plate 150, used for fixed connection with the first main fixing plate 150. The rotatable connecting end 152a is the other end of the second fixed connector 152 away from the first main fixing plate 150, used for connecting the first support member 104. The rotatable connecting end 152a is provided with an arc-shaped groove 1520, which serves as an installation space for part of the connector of the first support member 104.

[0262] The fixed end 152b may be provided with multiple fastening holes 1521 and multiple limiting posts 1522. The multiple fastening holes 1521 of the second fixed connector 152 are aligned with some of the fastening holes 1503 of the first main fixing plate 150. This application allows fasteners to be inserted into the fastening holes 1521 of the second fixed connector 152 and the fastening holes 1503 of the first main fixing plate 150 to lock the second fixed connector 152 to the first main fixing plate 150. The multiple limiting posts 1522 are located on the lower surface of the second fixed connector 152 facing the first main fixing plate 150 and are used to cooperate with the limiting holes 1504 of the first main fixing plate 150 to limit the installation position of the second fixed connector 152 relative to the first main fixing plate 150.

[0263] For example, the structure of the fourth fixing member 154 can be referred to that of the second fixing member 152, and will not be described again here. Understandably, the structure of the fourth fixing member 154 may be the same as or different from that of the second fixing member 152, and this application does not limit it in this regard.

[0264] Please refer to the following: Figure 28 and Figure 31 , Figure 31 yes Figure 7 The exploded structural diagram of the second fastener 16 shown.

[0265] For example, the structure of the second fixing member 16 can be referenced to that of the first fixing member 15, and will not be described again here. The structure of the second fixing member 16 is the same as that of the first fixing member 15, and the second fixing member 16 and the first fixing member 15 are mirror-symmetrically arranged relative to the rotating shaft assembly 10. The second fixing member 16 may also include a second main fixing plate 160 and a plurality of fixing connectors (161, 162, 163, 164, 165), and is connected to the second support member 105 through the plurality of fixing connectors (161, 162, 163, 164, 165). The second main fixing plate 160 may be provided with a plurality of connection structures, including a connection notch 1601, a plurality of mounting notches 1602, a plurality of fastening holes 1603, a plurality of limiting holes 1604, a plurality of connecting blocks 1605, and a plurality of second sliding grooves 1606, etc. Understandably, the structure of the second fixing member 16 may also be different from that of the first fixing member 15, and this application does not limit it in this regard.

[0266] Please refer to the following: Figure 32 , Figure 33A and Figure 33B , Figure 32 yes Figure 7 The diagram shows the assembly structure of the first fixing member 15 and the second fixing member 16 with the rotating shaft assembly 10, and is shown in conjunction with the reference. Figure 28 The first fastener 15 shown and Figure 31 The second fastener 16 is shown; Figure 33A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C1-C1. Figure 33B yes Figure 33A The diagram shows the structure in its closed state. Figure 32 The position of C1-C1 corresponds to Figure 8 The position of A1-A1. The cross section cut along C1-C1 passes through the first main fixing plate 150 of the first fixing member 15, the first connecting member 1041 of the first support member 104, the first main support plate 1011 of the top shaft 101, the first connecting member 1051 of the second support member 105, and the second main fixing plate 160 of the second fixing member 16.

[0267] In some embodiments, the distal shaft portion 1041a of the first connector 1041 of the first support member 104 is mounted on the first connection notch 1501 of the first fixing member 15, and the distal shaft portion 1051a of the first connector 1051 of the second support member 105 is mounted on the first connection notch 1601 of the second fixing member 16.

[0268] When in the closed state, the distal shaft portion 1041a of the first connector 1041 of the first support member 104 is embedded in the first connection notch 1501 of the first fixing member 15, and the lower end of the distal shaft portion 1041a contacts the first side wall 15011 of the first connection notch 1501 and the second side wall 15012 of the first main fixing plate 150 of the first fixing member 15; the distal shaft portion 1051a of the first connector 1051 of the second support member 105 is embedded in the first connection notch 1601 of the second fixing member 16, and the lower end of the distal shaft portion 1051a contacts the first side wall 16011 of the first connection notch 1601 and the second side wall 16012 of the second main fixing plate 160 of the second fixing member 16. In this application, the distal shaft portion 1041a of the first connector 1041 of the first support member 104 can cooperate with the first connection notch 1501 of the first fixing member 15, and the distal shaft portion 1051a of the first connector 1051 of the second support member 105 can also cooperate with the first connection notch 1601 of the second fixing member 16, so that the first fixing member 15 and the second fixing member 16 are tightly connected with the rotating shaft assembly 10.

[0269] In this application, the proximal portion 1041b and the distal portion 1041a of the first connector 1041 of the first support member 104 are respectively embedded into the first notch 1011a of the top shaft 101 of the rotating shaft assembly 10 and the first connection notch 1501 of the first fixing member 15. The proximal portion 1041b and the distal portion 1041a cooperate with the first notch 1011a and the first connection notch 1501 respectively, so that the first fixing member 15, the first support member 104 and the main shaft 100 of the rotating shaft assembly 10 have a high degree of fit and are tightly connected. Furthermore, the proximal portion 1051b and distal portion 1051a of the first connector 1051 of the second support member 105 are respectively embedded into the second notch 1011b of the top shaft 101 of the pivot assembly 10 and the first connecting notch 1601 of the second fixing member 16. The proximal portion 1051b and distal portion 1051a cooperate with the second notch 1011b and the first connecting notch 1601, respectively, resulting in a high degree of fit and tight connection between the second fixing member 16, the second support member 105, and the main shaft 100 of the pivot assembly 10. Therefore, the overall structure of the folding assembly 1, composed of the pivot assembly 10, the first fixing member 15, and the second fixing member 16, is complete and stable, thus providing a stable support environment for the screen 200 and ensuring the display performance and touch control performance of the screen 200.

[0270] Please refer to the following: Figure 32 , Figure 34A and Figure 34B , Figure 34A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C2-C2. Figure 34B yes Figure 34A The diagram shows the structure in its closed state. Figure 32 The position of C2-C2 corresponds to Figure 8 The section cut along C2-C2 passes through the first fixing member 15, the second connecting member 1042 of the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second connecting member 1052 of the second support member 105, and the first fixing connecting member 161 of the second fixing member 16.

[0271] In some embodiments, the second connector 1052 of the second support member 105 is rotatably connected to the second fixing member 16. Specifically, a portion of the distal axis portion 1052a of the second connector 1052 of the second support member 105 is mounted in the arcuate groove 1610 of the first fixing connector 161 of the second fixing member 16, thereby rotatably connecting the second fixing member 16 via a virtual axis connection. Furthermore, the distal axis portion 1052a of the second connector 1052 can slide along the arcuate groove 1610, allowing the second fixing member 16 to move closer to or further away from the second support member 105, i.e., closer to or further away from the main shaft 100 of the rotating shaft assembly 10.

[0272] In some other embodiments, the distal shaft portion 1052a of the second connector 1052 may also be rotatably connected to the second fixing member 16 via a solid shaft connection, and this application does not impose strict limitations on this.

[0273] Please refer to the following: Figure 32 , Figure 35A and Figure 35B , Figure 35A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C3-C3. Figure 35B yes Figure 35A The diagram shows the structure in its closed state. Figure 32 The position of C3-C3 corresponds to Figure 8 The section cut along C3-C3 passes through the first fixing member 151 of the first fixing member 15, the second fixing member 16, the second connecting member 1042 of the first support member 104, the second connecting member 1052 of the second support member 105, the first mounting member 1012 of the top shaft 101, and the first main support plate 1011 of the top shaft 101.

[0274] In some embodiments, the second connector 1042 of the first support member 104 is rotatably connected to the first fixing member 15. Specifically, a portion of the distal axis portion 1042a of the second connector 1042 of the first support member 104 is mounted in the arcuate groove 1510 of the first fixing connector 151 of the first fixing member 15, thereby rotatably connecting the first fixing member 15 via a virtual axis connection. Furthermore, the distal axis portion 1042a of the second connector 1042 can slide along the arcuate groove 1510, allowing the first fixing member 15 to move closer to or further away from the first support member 104, i.e., closer to or further away from the main shaft 100 of the rotating shaft assembly 10.

[0275] In some other embodiments, the distal shaft portion 1042a of the second connector 1042 may also be rotatably connected to the first fixing member 15 via a solid shaft connection, and this application does not impose strict limitations on this.

[0276] Please refer to the following: Figures 34A to 35B The second connector 1042 of the first support member 104 rotatably connects the top shaft 101 and the first fixing member 15, and the second connector 1042 of the second support member 105 rotatably connects the top shaft 101 and the second fixing member 16. Therefore, the first fixing member 15 and the second fixing member 16 can unfold or fold relative to the top shaft 101 as the first support member 104 and the second support member 105 move relative to the top shaft 101. Figure 34A and Figure 35A As shown, when in the open state, the first fixing member 15 and the second fixing member 16 can move away from each other and, driven by the first support member 104 and the second support member 105, move away from the main shaft 100 of the rotating shaft assembly 10. Figure 34B and Figure 35B As shown, when in the closed state, the first fixing member 15 and the second fixing member 16 can approach each other and approach the main shaft 100 of the rotating shaft assembly 10 under the drive of the first support member 104 and the second support member 105.

[0277] Please refer to the following: Figure 32 , Figure 36A and Figure 36B , Figure 36A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C4-C4. Figure 36B yes Figure 36A The diagram shows the structure in its closed state. Figure 32 The position of C4-C4 corresponds to Figure 8The section cut along C4-C4 passes through the second fixing connector 152 of the first fixing member 15, the third connector 1043 of the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the third connector 1053 of the second support member 105, and the second fixing connector 162 of the second fixing member 16.

[0278] In some embodiments, the third connector 1043 of the first support member 104 is rotatably connected to the first fixing member 15. A portion of the distal axis portion 1043a of the third connector 1043 is mounted in the arcuate groove 1520 of the second fixing connector 152 of the first fixing member 15, thus rotatably connecting the first fixing member 15 via a virtual axis connection. The distal axis portion 1043a of the third connector 1043 can slide along the arcuate groove 1520, allowing the first fixing member 15 to move closer to or further away from the first support member 104, i.e., closer to or further away from the main shaft 100 of the rotating shaft assembly 10. The third connector 1053 of the second support member 105 is rotatably connected to the second fixing member 16. A portion of the distal axis portion 1053a of the third connector 1053 of the second support member 105 is mounted in the arcuate groove 1620 of the second fixing connector 162 of the second fixing member 16, thus rotatably connecting the second fixing member 16 via a virtual axis connection. The distal portion 1053a of the third connector 1053 slides along the arcuate groove 1620, causing the second fixing member 16 to move closer to or further away from the second support member 105, that is, closer to or further away from the main shaft 100 of the rotating shaft assembly 10. Therefore, the first fixing member 15 and the second fixing member 16 can be unfolded or folded relative to the main shaft 100 of the rotating shaft assembly 10 under the action of the first support member 104 and the second support member 105.

[0279] In some other embodiments, the distal shaft portion 1043a of the third connector 1043 may also be rotatably connected to the first fixing member 15 via a solid shaft connection, and / or the distal shaft portion 1053a of the third connector 1053 may also be rotatably connected to the second fixing member 16 via a solid shaft connection. This application does not impose strict limitations on these embodiments.

[0280] Please refer to the following: Figure 32 , Figure 37A and Figure 37B , Figure 37A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C5-C5. Figure 37B yes Figure 37A The diagram shows the structure in its closed state. Figure 32 The position of C5-C5 corresponds to Figure 8The section cut along C5-C5 passes through the first main fixing plate 150 of the first fixing member 15, the first gear connecting rod 106, the first main support plate 1011 of the top shaft 101, the second gear connecting rod 107, and the second main fixing plate 160 of the second fixing member 16.

[0281] In some embodiments, the sliding block 1062a of the sliding end 1062 of the first gear connecting rod 106 is installed in the first groove 1506 of the first main fixing plate 150 of the first fixing member 15. The sliding end 1062 of the first gear connecting rod 106 can slide along the first groove 1506 of the first fixing member 15, so that the sliding end 1062 of the first gear connecting rod 106 is slidably connected to the first fixing member 15. The sliding block 1072a of the sliding end 1072 of the second gear connecting rod 107 is installed in the second groove 1606 of the second main fixing plate 160 of the second fixing member 16. The sliding end 1072 of the second gear connecting rod 107 can slide along the second groove 1606 of the second fixing member 16, so that the sliding end 1072 of the second gear connecting rod 107 is slidably connected to the second fixing member 16.

[0282] Please refer to the following: Figure 32 , Figure 38A and Figure 38B , Figure 38A yes Figure 32 The diagram shows a cross-sectional view of the assembled structure taken along line C6-C6. Figure 38B yes Figure 38A The diagram shows the structure in its closed state. Figure 32 The position of C6-C6 corresponds to Figure 8 The position of A7-A7. The section cut along C6-C6 passes through the first main fixing plate 150 of the first fixing member 15, the fourth connecting member 1044 of the first support member 104, the second main support plate 1021 of the central axis 102, the fourth connecting member 1054 of the second support member 105, and the second main fixing plate 160 of the second fixing member 16.

[0283] In some embodiments, the notch at the lower end of the distal shaft portion 1044a of the fourth connector 1044 can cooperate with the connecting block 1505 of the first main fixing plate 150 of the first fixing member 15, and the notch at the lower end of the distal shaft portion 1054a of the fourth connector 1054 can cooperate with the connecting block 1605 of the second main fixing plate 160 of the second fixing member 16, so that the first fixing member 15 and the second fixing member 16 have a high degree of fit and tight connection with the rotating shaft assembly 10.

[0284] For example, the connecting block 1505 of the first fixing member 15 can also cooperate with the sixth connecting member 1046 of the first support member 104, and the cooperation structure between the two can be referred to as the connection block 1505 of the first fixing member 15 and the fourth connecting member 1044 of the first support member 104, which will not be described again here. The connecting block 1605 of the second fixing member 16 can also cooperate with the sixth connecting member 1056 of the second support member 105, and the cooperation structure between the two can be referred to as the connection block 1605 of the second fixing member 16 and the fourth connecting member 1054 of the second support member 105, which will not be described again here.

[0285] For example, the connection structure between the third fixing connector 153 and the fifth fixing connector 155 of the first fixing member 15 and the rotating shaft assembly 10 can refer to the connection structure between the first fixing connector 151 of the first fixing member 15 and the rotating shaft assembly 10, and the connection structure between the third fixing connector 163 and the fifth fixing connector 165 of the second fixing member 16 and the rotating shaft assembly 10 can refer to the connection structure between the first fixing connector 161 of the second fixing member 16 and the rotating shaft assembly 10, and will not be described again here.

[0286] For example, the connection structure between the fourth fixing connector 154 of the first fixing member 15 and the rotating shaft assembly 10 can be referred to the connection structure between the second fixing connector 152 of the first fixing member 15 and the rotating shaft assembly 10, and the connection structure between the fourth fixing connector 164 of the second fixing member 16 and the rotating shaft assembly 10 can be referred to the connection structure between the second fixing connector 162 of the second fixing member 16 and the rotating shaft assembly 10, which will not be described again here.

[0287] Please refer to the following: Figure 32 , Figures 33A to 36B , Figure 38A and Figure 38B .like Figure 32 and Figures 34A to 36B As shown, in this application, the fixing connectors (151, 152, 153, 154, 155) of the first fixing member 15 are rotatably connected to the rotating shaft assembly 10, and the fixing connectors (161, 162, 163, 164, 165) of the second fixing member 16 are rotatably connected to the rotating shaft assembly 10, so that the first fixing member 15 and the second fixing member 16 can relatively unfold and relatively fold with the deformation of the rotating shaft assembly 10. Furthermore, as... Figure 32 , Figure 33A , Figure 33B , Figure 38A and Figure 38BAs shown, the connecting notch 1501 and multiple connecting blocks 1505 of the first fixing member 15 cooperate with the mating connecting parts (1041, 1044, 1046, 1049) of the first support member 104, and the connecting notch 1601 and multiple connecting blocks 1605 of the second fixing member 16 cooperate with the mating connecting parts (1051, 1054, 1056, 1059) of the second support member 105. Therefore, the overall structure of the folding assembly 1 composed of the hinge assembly 10, the first fixing member 15, and the second fixing member 16 is complete and has good stability, thereby providing a stable support environment for the screen 200 and ensuring the display performance and touch control performance of the screen 200.

[0288] Please refer to the following: Figures 4 to 7 In some embodiments, the first middle frame 22 and the second middle frame 32 are fixedly connected to the second fixing member 16 and the first fixing member 15, respectively. When the electronic device 1000 is closed from the open state, the first middle frame 22 and the second middle frame 32 can rotate relative to the pivot assembly 10 and move closer to the pivot assembly 10 under the action of the second fixing member 16 and the first fixing member 15. Conversely, when the electronic device 1000 is opened from the closed state, the first middle frame 22 and the second middle frame 32 rotate relative to the pivot assembly 10 and move away from the pivot assembly 10 under the action of the second fixing member 16 and the first fixing member 15. The first rear cover 21 and the second rear cover 31 also move closer to or away from the pivot assembly 10 as the first middle frame 22 and the second middle frame 32 move.

[0289] In this application, multiple connecting components (11, 12, 13, 14) are rotatably connected to the pivot assembly 10 and are capable of driving the first shielding member 17 and the second shielding member 18 to move relative to the pivot assembly 10. For example, this application designs the structure of the connecting components (11, 12, 13, 14) so ​​that the first shielding member 17 and the second shielding member 18 can relatively unfold and fold as the pivot assembly 10 deforms.

[0290] like Figure 7 As shown, the first connecting component 11 and the second connecting component 12 are installed in the top mounting space of the shaft assembly 10, and the third connecting component 13 and the fourth connecting component 14 are installed in the bottom mounting space of the shaft assembly 10. The top mounting space of the shaft assembly 10 for installing the first connecting component 11 and the second connecting component 12 will be described below with reference to the accompanying drawings.

[0291] Please refer to the following: Figure 9 and Figure 10In some embodiments, the first main support plate 1011 of the top shaft 101 may also have multiple arc-shaped surfaces (10111, 10112, 10113, 10114, 10115, 10116). The multiple arc-shaped surfaces (10111, 10112, 10113, 10114, 10115, 10116) are used to cooperate with the structure of the first mounting member 1012 and the second mounting member 1013 to form a partial top mounting space for mounting the first connecting assembly 11 and the second connecting assembly 12.

[0292] For example, the plurality of arc-shaped surfaces (10111, 10112, 10113, 10114, 10115, 10116) may include a first arc-shaped surface 10111, a second arc-shaped surface 10112, a third arc-shaped surface 10113, a fourth arc-shaped surface 10114, a fifth arc-shaped surface 10115, and a sixth arc-shaped surface 10116. The first arc-shaped surface 10111, the second arc-shaped surface 10112, the third arc-shaped surface 10113, and the fourth arc-shaped surface 10114 are used to mate with the structure of the first mounting member 1012, and the fifth arc-shaped surface 10115 and the sixth arc-shaped surface 10116 are used to mate with the structure of the second mounting member 1013.

[0293] The first arc-shaped surface 10111 and the second arc-shaped surface 10112 are respectively located on both sides of the first main support plate 1011. The first arc-shaped surface 10111 and the second arc-shaped surface 10112 are staggered. The third arc-shaped surface 10113 and the fourth arc-shaped surface 10114 are staggered. The structure of the third arc-shaped surface 10113 can be designed with reference to the design of the second arc-shaped surface 10112, and the structure of the fourth arc-shaped surface 10114 can be designed with reference to the design of the first arc-shaped surface 10111, which will not be described in detail here.

[0294] For example, a second arcuate surface 10112 is disposed on the top side of the limiting member 1015, and a third arcuate surface 10113 is disposed on the bottom side of the limiting member 1015. A first clearance notch 1015a is provided between the second arcuate surface 10112 and the limiting member 1015, and a second clearance notch 1015b is provided between the third arcuate surface 10113 and the limiting member 1015. The first clearance notch 1015a and the second clearance notch 1015b are used to avoid part of the structure of the first connecting assembly 11, so that the first connecting assembly 11 moves smoothly and stably relative to the rotating shaft assembly 10.

[0295] For example, the fifth arc-shaped surface 10115 has its groove wall in the middle of the first main support plate 1011 protruding relative to the upper surface of the first main support plate 1011. The sixth arc-shaped surface 10116 has its groove wall in the middle of the first main support plate 1011 protruding relative to the upper surface of the first main support plate 1011.

[0296] In some embodiments, the first mounting member 1012 is provided with multiple mating arc surfaces (1012g, 1012h, 1012j, 1012k). These multiple mating arc surfaces correspond to portions of the arc surfaces (10111, 10112, 10113, 10114) of the first main support plate 1011 and mate with these arc surfaces to form the mounting space of the first mounting member 1012, used to install portions of the first connecting component 11 and the second connecting component 12. Specific connection methods will be described later. Specifically, the multiple mating arc surfaces (1012g, 1012h, 1012j, 1012k) include a first mating arc surface 1012g, a second mating arc surface 1012h, a third mating arc surface 1012j, and a fourth mating arc surface 1012k.

[0297] For example, there is a gap between the first mating arc surface 1012g and the second mating arc surface 1012h, and the upper surface of the first mounting member 1012 is provided with a first opening 10125, which is located in the middle of the first mounting member 1012.

[0298] Understandably, a gap may also exist between the third mating arc surface 1012j and the fourth mating arc surface 1012k, and the upper surface of the first mounting member 1012 may also have an opening corresponding to the gap, the opening penetrating the upper surface of the first mounting member 1012 and communicating with the gap. In some other embodiments, the first mounting member 1012 may not have an opening, or may have a partial opening.

[0299] In some embodiments, the second mounting member 1013 has a fifth mating arc surface 1013a and a sixth mating arc surface 1013b, which are staggered. The second mounting member 1013 may also have a second opening 10127 and a third opening 10128. The second opening 10127 and the third opening 10128 are staggered and located in the middle of the second mounting member 1013.

[0300] Please refer to the following: Figure 8 , Figure 39A and Figure 39B , Figure 39A yes Figure 8 A schematic diagram of the cross-sectional structure of the top shaft 101 of the rotating shaft assembly 10 along line A8-A8. Figure 39B yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 of the rotating shaft assembly 10 along line A9-A9. Both the cross-section along line A8-A8 and the cross-section along line A9-A9 pass through the first mounting member 1012 and the first main support plate 1011 of the top shaft 101.

[0301] In some embodiments, the first arcuate surface 10111 of the first main support plate 1011 and the first mating arcuate surface 1012g of the first mounting member 1012 mate to form a first mounting space 10121 for mounting a portion of the structure of the first connecting assembly 11. The second arcuate surface 10112 of the first main support plate 1011 and the second mating arcuate surface 1012h of the first mounting member 1012 mate to form a second mounting space 10122 for mounting a portion of the structure of the second connecting assembly 12. The first opening 10125 penetrates the upper surface of the first mounting member 1012 and connects the first mounting space 10121 and the second mounting space 10122.

[0302] Understandably, the third arc-shaped surface 10113 of the first main support plate 1011 can also mate with the third mating arc-shaped surface 1012j of the first mounting member 1012 to form an installation space for installing a portion of the structure of the first connecting assembly 11. The fourth arc-shaped surface 10114 of the first main support plate 1011 can also mate with the fourth mating arc-shaped surface 1012k of the first mounting member 1012 to form an installation space for installing a portion of the structure of the second connecting assembly 12, which will not be elaborated further here.

[0303] Please refer to the following: Figure 8 , Figure 40A and Figure 40B , Figure 40A yes Figure 8 The schematic diagram shows the cross-sectional structure of the top shaft 101 of the rotating shaft assembly 10 along line A10-A10. Figure 40B yes Figure 8 The diagram shows a cross-sectional view of the top shaft 101 of the rotating shaft assembly 10 along line A11-A11. Both the cross-section along line A10-A10 and the cross-section along line A11-A11 pass through the second mounting member 1013 of the top shaft 101 and the first main support plate 1011 of the top shaft 101.

[0304] In some embodiments, the fifth arcuate surface 10115 of the first main support plate 1011 and the fifth mating arcuate surface 1013a of the second mounting member 1013 mate to form a third mounting space 10123 for mounting a portion of the structure of the first connecting assembly 11. The sixth arcuate surface 10116 of the first main support plate 1011 and the sixth mating arcuate surface 1013b of the second mounting member 1013 mate to form a fourth mounting space 10124 for mounting a portion of the structure of the second connecting assembly 12. The second opening 10127 penetrates the upper surface of the second mounting member 1013 and communicates with the third mounting space 10123, and the third opening 10128 penetrates the upper surface of the second mounting member 1013 and communicates with the fourth mounting space 10124. Furthermore, the second opening 10127 and the third opening 10128 may or may not be connected; this application does not limit this.

[0305] For example, the bottom shaft 103 of the pivot assembly 10 may also have a portion of bottom mounting space for mounting the third connecting assembly 13 and the fourth connecting assembly 14, and the top mounting space of the top shaft 101 can be referenced, which will not be described in detail here.

[0306] The structure of connecting components (11, 12, 13, 14) in this embodiment of the application will be described below with reference to the accompanying drawings. Connecting components (11, 12, 13, 14) may also have other structures, which are not limited in this application. Please refer to the accompanying drawings. Figure 7 and Figure 41 , Figure 41 yes Figure 7 The diagram shows the structure of the first connecting component 11.

[0307] In some embodiments, the first connecting assembly 11 may include a first rotating member 111, a second rotating member 112, a first damping member 113, a first elastic member 114, and a second elastic member 115. Both the first rotating member 111 and the second rotating member 112 are rotatably connected to the rotating shaft assembly 10 and are spaced apart. The first damping member 113 and the first elastic member 114 are mounted on the first rotating member 111, and the second elastic member 115 is mounted on the second rotating member 112.

[0308] Please refer to the following: Figure 7 , Figure 41 and Figure 42 , Figure 42 yes Figure 41 An exploded view of a portion of the structure of the first connecting component 11 shown. Figure 42 The structure of the first rotating member 111, the first damping member 113, and the first elastic member 114 is shown.

[0309] In some embodiments, the first rotating member 111 may include a first arcuate arm 1111 and a second arcuate arm 1112. The first arcuate arm 1111 and the second arcuate arm 1112 are used for rotatable connection with the rotating shaft assembly 10. In this application, the first rotating member 111 is rotatably connected to the rotating shaft assembly 10 through the first arcuate arm 1111 and the second arcuate arm 1112 to increase the connection strength between the first rotating member 111 and the rotating shaft assembly 10. In other embodiments, the first rotating member 111 may include either the first arcuate arm 1111 or the second arcuate arm 1112, and is rotatably connected to the rotating shaft assembly 10 through either the first arcuate arm 1111 or the second arcuate arm 1112; this application does not limit this aspect.

[0310] The first arc-shaped arm 1111 and the second arc-shaped arm 1112 may be provided with a clearance structure to avoid a portion of the structure of the rotating shaft assembly 10, so that the rotation of the first rotating member 111 relative to the rotating shaft assembly 10 is smooth and stable. For example, the first arc-shaped arm 1111 may be provided with a first clearance notch 1111a, and the second arc-shaped arm 1112 may be provided with a first clearance notch 1112a. In other embodiments, the first arc-shaped arm 1111 and the second arc-shaped arm 1112 may also be provided with grooves or other clearance structures, or may not be provided with clearance structures; this application does not limit this.

[0311] The first arc-shaped arm 1111 and the second arc-shaped arm 1112 may be provided with a mating structure for engaging with the mating structure of the second connecting component 12, so that the connection between the first connecting component 11 and the second connecting component 12 is tight and has a high degree of fit. The mating structure may include protrusions, grooves, etc. For example, the first arc-shaped arm 1111 may be provided with a second clearance notch 1111b, and the second arc-shaped arm 1112 may be provided with a limiting block 1112b. In some other embodiments, the first arc-shaped arm 1111 and the second arc-shaped arm 1112 may also be provided with other mating structures, or may not be provided with mating structures, and this application does not limit this.

[0312] For example, the first rotating member 111 may also be provided with a first receiving groove 1114, a first sliding groove 1115, a second receiving groove 1116, and a second sliding groove 1117. The first receiving groove 1114 is located on the side of the second arc-shaped arm 1112 facing away from the rotating shaft assembly 10. The first sliding groove 1115 is located between the first arc-shaped arm 1111 and the second arc-shaped arm 1112, and communicates with the first receiving groove 1114.

[0313] The second receiving groove 1116 is located at the end of the first arc-shaped arm 1111 facing away from the rotating shaft assembly 10, and the first elastic member 114 is mounted in the second receiving groove 1116. The second receiving groove 1116 has a distal end 1116a and a proximal end 1116b disposed opposite to each other. The distal end 1116a of the second receiving groove 1116 is the end of the second receiving groove 1116 near the first arc-shaped arm 1111. The first elastic member 114 includes a fixed end and a movable end disposed opposite to each other. The fixed end of the first elastic member 114 is fixed to the groove wall of the proximal end 1116b of the second receiving groove 1116, and the movable end of the first elastic member 114 can slide along the second receiving groove 1116. For example, the first rotating member 111 may further include a connector 1113, which can be fixedly installed on the groove wall of the near-axial end 1116b of the second receiving groove 1116. The fixed end of the first elastic member 114 can be fixed to the connector 1113 and fixedly installed on the second receiving groove 1116 through the connector 1113 for easy replacement; it can also be directly fixedly connected to the groove wall of the second receiving groove 1116 by means of bonding, welding, etc. For example, the first elastic member 114 can be an elastic structure such as a spring or a sheet, or other elastic structures, which are not limited in this application.

[0314] For example, the second sliding groove 1117 can be located on the side of the first rotating member 111 and extend in a direction away from the rotating shaft assembly 10. There can be two second sliding grooves 1117, located on opposite sides of the first rotating member 111, or there can be only one; this application does not limit the number. For example, the second sliding groove 1117 has two oppositely arranged upper sidewalls 1117a and lower sidewalls 1117b, which are recessed to jointly form the guide space of the second sliding groove 1117. That is, the sidewalls of the second sliding groove 1117 can have recessed guide spaces to guide the sliding direction of the structural member installed in the second sliding groove 1117, making the relative sliding action between the first rotating member 111 and the corresponding structural member easier to achieve and providing higher control precision.

[0315] For example, the first rotating member 111 may further include a cover plate 1118, which is located above the first receiving groove 1114 and fixed to the groove of the first receiving groove 1114. The cover plate 1118 serves to shield and protect the first damping member 113, and can also be used to block the first damping member 113 and the first sliding member 110, preventing the first sliding member 110 from rubbing against the first damping member 113 when sliding relative to the first rotating member 111. The cover plate 1118 may have fastening holes to allow fasteners to pass through, and the groove of the first receiving groove 1114 may also correspondingly have fastening holes to allow fasteners to pass through. In this application, fasteners can be inserted into the fastening holes of the cover plate 1118 and the fastening holes of the groove of the first receiving groove 1114 to lock the cover plate 1118 to the first receiving groove 1114. Understandably, the cover plate 1118 and the first receiving groove 1114 can also be fixedly connected by riveting, welding, gluing or other means, and this application does not limit this.

[0316] Please refer to the following: Figure 41 and Figure 43 , Figure 43 yes Figure 42 An exploded view of the structure of the first damping element 113. In some embodiments, the first damping element 113 may include a bracket 1133 and an elastic element 1134. The bracket 1133 includes a proximal end 1133a and a distal end 1133b disposed opposite to each other. The proximal end 1133a of the bracket 1133 contacts or abuts the main shaft 100. The distal end 1133b of the bracket 1133 and the elastic element 1134 are mounted in a first receiving groove 1114. One end of the elastic element 1134 is connected to the distal end 1133b of the bracket 1133, and the other end contacts or abuts the groove wall of the first receiving groove 1114.

[0317] The proximal end 1133a of the bracket 1133 may include a sleeve 1131 and a rotating shaft 1132. The sleeve 1131 is fitted onto the rotating shaft 1132 and is rotatable relative to the rotating shaft 1132. The sleeve 1131 contacts or abuts against the main shaft 100. The proximal end 1133a of the bracket 1133 has a notch. Both ends of the rotating shaft 1132 are fixed to the sidewalls of the notch. The sleeve 1131 is rotatably mounted on the bracket 1133 by fitting onto the rotating shaft 1132.

[0318] The elastic element 1134 can contact or abut against the wall of the bracket 1133 and the first receiving groove 1114. For example, the bracket 1133 may be provided with a support member 1135, and the elastic element 1134 can be sleeved on the support member 1135 and move relative to the support member 1135. The elastic element 1134 may include multiple elastic structures such as springs to increase the damping force of the first damping member 113. Correspondingly, there may also be multiple support members 1135, and the number of support members 1135 is equal to the number of elastic structures.

[0319] The bracket 1133 is larger than the first sliding groove 1115 to prevent the bracket 1133 from sliding out of the first sliding groove 1115.

[0320] Please refer to the following: Figure 41 and Figure 44 , Figure 44 yes Figure 41 An exploded view of the structure of the second rotating member 112 and the second elastic member 115. In some embodiments, the second rotating member 112 may include a third arcuate arm 1121 and a third receiving groove 1122. The third arcuate arm 1121 is rotatably connected to the rotating shaft assembly 10, and the third receiving groove 1122 is located at the end of the third arcuate arm 1121 facing away from the rotating shaft assembly 10. The second elastic member 115 is mounted in the third receiving groove 1122. The second elastic member 115 includes a proximal end 115a and a distal end 115b disposed opposite to each other. The distal end 115b of the second elastic member 115 is fixed to the groove wall of the third receiving groove 1122 on the side away from the third arcuate arm 1121. The proximal end 115a of the second elastic member 115 can slide along the third receiving groove 1122, that is, slide relative to the second rotating member 112.

[0321] For example, the second rotating member 112 may further include a connector 1123, which can be fixedly installed on the wall of the third receiving groove 1122. The second elastic member 115 can be fixedly connected to the connector 1123 and fixedly installed on the third receiving groove 1122 through the connector 1123 for easy replacement; it can also be directly fixedly connected to the wall of the third receiving groove 1122 by means of bonding, welding, etc. For example, the second elastic member 115 can adopt an elastic structure such as a spring or a sheet, or other elastic structures; the second elastic member 115 can adopt the same elastic structure as the first elastic member 114, or it can adopt a different elastic structure than the first elastic member 114, and this application does not limit it in this regard.

[0322] For example, the second rotating member 112 may also be provided with a third sliding groove 1124. For example, the third sliding groove 1124 may be located on the side of the third arc-shaped arm 1121 and extend in a direction away from the rotating shaft assembly 10. The third arc-shaped arm 1121 may be provided with two third sliding grooves 1124, respectively located on two opposite sides of the third arc-shaped arm 1121, or the third arc-shaped arm 1121 may be provided with only one third sliding groove 1124, which is not limited in this application. For example, the third sliding groove 1124 has two oppositely arranged upper sidewalls 1124a and lower sidewalls 1124b, and the two oppositely arranged sidewalls are recessed to jointly form the guide space of the third sliding groove 1124. That is, the sidewalls of the third sliding groove 1124 may have recessed guide spaces to guide the sliding direction of the structural member installed in the third sliding groove 1124, making the relative sliding action between the second rotating member 112 and the corresponding structural member easier to achieve and the control precision higher.

[0323] Please refer to the following: Figure 7 , Figure 45A and Figure 45B , Figure 45A yes Figure 7 The diagram shows the assembly structure of the first rotating member 111 and the second rotating member 112 of the first connecting assembly 11, the third rotating member 121 and the fourth rotating member 122 of the second connecting assembly 12, and the first main support plate 1011 of the top shaft 101 of the rotating shaft assembly 10. Figure 45B yes Figure 45A A schematic diagram of the assembly structure shown from another angle, in conjunction with reference to... Figure 42 The structure of the first rotating member 111 shown and Figure 44 The structure of the second rotating member 112 shown. Figure 45B The perspective shown is relative Figure 45A The view shown has been flipped left and right.

[0324] For example, the second connecting assembly 12 may also include a third rotating member 121, a fourth rotating member 122, a second damping member 123, a first elastic member 114, and a second elastic member 125. The third rotating member 121 and the fourth rotating member 122 are both rotatably connected to the rotating shaft assembly 10 and are spaced apart. The second damping member 123 and the first elastic member 114 are mounted on the third rotating member 121, and the second elastic member 125 is mounted on the fourth rotating member 122. The third rotating member 121 may include a first arcuate arm 1211 and a second arcuate arm 1212, and the fourth rotating member 122 of the second connecting assembly 12 includes a third arcuate arm 1221. The first arcuate arm 1211, the second arcuate arm 1212, and the third arcuate arm 1221 are used for rotatably connecting to the rotating shaft assembly 10.

[0325] For example, the third rotating member 121 may also be provided with a first receiving groove 1214, a fourth sliding groove 1215, a second receiving groove 1216 and a fifth sliding groove 1217.

[0326] For example, the fourth rotating member 122 may also include a third receiving groove 1222 and a sixth sliding groove 1224, with the second elastic member 125 mounted in the third receiving groove 1222.

[0327] Understandably, the structure of the second connecting component 12 can be referenced from that of the first connecting component 11, and will not be described again here.

[0328] Understandably, the structural design of the third connecting component 13 and the fourth connecting component 14 can refer to the first connecting component 11, and will not be described in detail here.

[0329] The following section describes the rotational connection structure between multiple connecting components (11, 12, 13, 14) and the main shaft 100 of the rotating shaft assembly 10. This article uses the rotational connection structure between the first connecting component 11 and the second connecting component 12 and the top shaft 101 as an example. The rotational connection structures between the third connecting component 13 and the fourth connecting component 14 and the bottom shaft 103 can be referred to the rotational connection structure between the first connecting component 11 and the second connecting component 12 and the top shaft 101, and will not be described again here.

[0330] Please refer to the following: Figure 45A and Figure 45B In some embodiments, the first clearance notch 1111a of the first arcuate arm 1111 of the first rotating member 111 and the first clearance notch 1211a of the first arcuate arm 1211 of the third rotating member 121 are used to avoid a portion of the structure of the first main support plate 1011 of the rotating shaft assembly 10, so that the rotation of the first connecting assembly 11 and the second connecting assembly 12 relative to the rotating shaft assembly 10 is smooth and stable. In addition, the second clearance notch 1111b of the first arcuate arm 1111 of the first rotating member 111 and the limiting block 1211b of the first arcuate arm 1211 of the third rotating member 121 cooperate to not only make the relative rotation of the first connecting assembly 11 and the second connecting assembly 12 with the rotating shaft assembly 10 smooth, but also limit the relative position of the first connecting assembly 11 and the second connecting assembly 12, so as to stabilize the structure formed by the first connecting assembly 11 and the second connecting assembly 12 and the rotating shaft assembly 10 and improve the structural stability of the folding assembly 1. Understandably, the first connecting component 11 and the second connecting component 12 can also cooperate through other structures to define the relative positions of the first connecting component 11 and the second connecting component 12. Alternatively, no structure for mutual cooperation may be provided between the first connecting component 11 and the second connecting component 12, and this application does not limit this.

[0331] Understandably, the connection structure between the second arcuate arm 1212 of the third rotating member 121 of the second connecting assembly 12 and the rotating shaft assembly 10 can refer to the connection method between the first arcuate arm 1211 of the third rotating member 121 of the second connecting assembly 12 and the rotating shaft assembly 10, and will not be described in detail here.

[0332] The third arcuate arm 1121 of the second rotating member 112 of the first connecting assembly 11 and the third arcuate arm 1221 of the fourth rotating member 122 of the second connecting assembly 12 are staggered to ensure smooth relative rotation between the first connecting assembly 11, the second connecting assembly 12 and the rotating shaft assembly 10.

[0333] In some embodiments, a first damping element 113 of the first connecting assembly 11 connects the first rotating member 111 and the shaft assembly 10, providing damping force during the rotation of the first rotating member 111 relative to the shaft assembly 10. A second damping element 123 of the second connecting assembly 12 connects the third rotating member 121 and the shaft assembly 10, providing damping force during the rotation of the third rotating member 121 relative to the shaft assembly 10. It is understood that the first connecting assembly 11 may not have a first damping element 113 and / or the second connecting assembly 12 may not have a second damping element 123; this application does not limit this.

[0334] Please refer to the following: Figure 9 , Figure 10 , Figure 45A and Figure 45B For example, the rotation center of the second rotating member 112 of the first connecting assembly 11 relative to the rotating shaft assembly 10 coincides with the rotation center of the first rotating member 111 of the first connecting assembly 11 relative to the rotating shaft assembly 10, so that the rotation of the first connecting assembly 11 relative to the rotating shaft assembly 10 is smooth and reliable. For example, the center of the first arcuate arm 1111 of the first rotating member 111, the center of the third arcuate arm 1121 of the second rotating member 112, the center of the first arcuate surface 10111 of the first main support plate 1011 of the rotating shaft assembly 10, and the center of the fifth arcuate surface 10115 coincide. Similarly, the rotation center of the fourth rotating member 122 of the second connecting assembly 12 relative to the rotating shaft assembly 10 coincides with the rotation center of the third rotating member 121 of the second connecting assembly 12 relative to the rotating shaft assembly 10, so that the rotation of the second connecting assembly 12 relative to the rotating shaft assembly 10 is smooth and reliable.

[0335] Please refer to the following: Figure 46 , Figure 47A and Figure 47B , Figure 46 yes Figure 7 The diagram shows a partial structural schematic of the assembly structure of the first connecting component 11, the second connecting component 12, and the rotating shaft assembly 10. Figure 47A yes Figure 46The diagram shows a cross-sectional view of the assembled structure taken along line D1-D1. Figure 47B yes Figure 47A The diagram shows the structure in its closed state. Figure 46 The position of D1-D1 corresponds to Figure 8 The position of A8-A8. The cross section cut along D1-D1 passes through the first fixing member 15, the first rotating member 111 of the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the third rotating member 121 of the second connecting assembly 12, and the second fixing member 16.

[0336] In some embodiments, one end of the first rotating member 111 of the first connecting assembly 11 is rotatably connected to the rotating shaft assembly 10, and the other end is slidably connected to the first fixing member 15.

[0337] In this assembly, the first arcuate arm 1111 of the first rotating member 111 of the first connecting component 11 is mounted in the first mounting space 10121 of the rotating shaft assembly 10, so as to rotatably connect to the rotating shaft assembly 10 through a virtual shaft connection. It is understood that the first rotating member 111 can also rotatably connect to the rotating shaft assembly 10 through a physical shaft connection, and this application does not strictly limit this. It is also understood that the connection structure between the second arcuate arm 1112 of the first rotating member 111 of the first connecting component 11 and the rotating shaft assembly 10 can refer to the connection structure between the first arcuate arm 1111 of the first rotating member 111 and the rotating shaft assembly 10, and will not be described again here.

[0338] The first arc-shaped arm 1111 extends into the first opening 10125 through the first mounting space 10121 to define the relative position of the first arc-shaped arm 1111 and the rotating shaft assembly 10 along the axial direction, so as to stabilize the structure of the folding assembly 1.

[0339] In this configuration, the second sliding groove 1117 of the first rotating member 111 engages with the first sliding groove 1506 of the second main fixing plate 150 of the first fixing member 15, allowing the first rotating member 111 to slide relative to the first fixing member 15. Specifically, the upper sidewall 1506a of the first sliding groove 1506 is embedded in the guide space of the second sliding groove 1117, and the lower sidewall 1117b of the second sliding groove 1117 is embedded in the guide space of the first sliding groove 1506. This interlocking arrangement of the first sliding groove 1506 and the second sliding groove 1117 enhances the connection strength between them, thereby increasing the connection strength between the first rotating member 111 and the first fixing member 15, and improving the structural stability of the folding assembly 1. Furthermore, the second sliding grooves 1117 on both sides of the first rotating member 111 are slidably connected to the first sliding groove 1506 of the first fixing member 15 (see [reference]). Figure 42This makes the sliding between the first fixing member 15 and the first rotating member 111 of the first connecting assembly 11 smoother.

[0340] Please refer to the following: Figure 46 , Figure 48A and Figure 48B , Figure 48A yes Figure 46 The diagram shows a cross-sectional view of the assembled structure taken along line D2-D2. Figure 48B yes Figure 48A The diagram shows the structure in its closed state. Figure 46 The position of D2-D2 corresponds to Figure 8 The position of A9-A9. The cross-section along D2-D2 passes through the first fixing member 15, the first rotating member 111 of the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the third rotating member 121 of the second connecting assembly 12, and the second fixing member 16.

[0341] In some embodiments, one end of the third rotating member 121 of the second connecting assembly 12 is rotatably connected to the rotating shaft assembly 10, and the other end is slidably connected to the second fixing member 16.

[0342] In this design, the first arcuate arm 1211 of the third rotating member 121 of the second connecting assembly 12 is mounted in the second mounting space 10122 of the rotating shaft assembly 10, thereby rotatably connecting to the rotating shaft assembly 10 via a virtual shaft connection. It is understood that the third rotating member 121 can also be rotatably connected to the rotating shaft assembly 10 via a physical shaft connection; this application does not strictly limit this. Understandably, the connection structure between the second arcuate arm 1212 of the third rotating member 121 and the rotating shaft assembly 10 can refer to the connection structure between the first arcuate arm 1211 of the third rotating member 121 and the rotating shaft assembly 10, and will not be elaborated further here.

[0343] The first arc-shaped arm 1211 extends into the first opening 10125 through the second mounting space 10122 to define the relative position of the first arc-shaped arm 1211 and the rotating shaft assembly 10 along the axial direction, so as to stabilize the structure of the folding assembly 1.

[0344] Specifically, the fifth sliding groove 1217 of the third rotating member 121 engages with the second sliding groove 1606 of the second main fixing plate 160 of the second fixing member 16, allowing the third rotating member 121 to slide relative to the second fixing member 16. The upper sidewall 1606a of the second sliding groove 1606 is embedded in the guide space of the fifth sliding groove 1217, and the lower sidewall 1217b of the fifth sliding groove 1217 is also embedded in the guide space of the second sliding groove 1606. This staggered engagement of the second sliding groove 1606 and the fifth sliding groove 1217 enhances the connection strength between them, thereby increasing the connection strength between the third rotating member 121 and the second fixing member 16, and improving the structural stability of the folding assembly 1. Furthermore, the fifth sliding grooves 1217 on both sides of the third rotating member 121 are slidably connected to the first sliding groove 1506 of the first fixing member 15, making the sliding between the first fixing member 15 and the third rotating member 121 of the second connecting assembly 12 smoother.

[0345] Please refer to the following: Figure 46 , Figure 49A and Figure 49B , Figure 49A yes Figure 46 The diagram shows a cross-sectional view of the assembled structure taken along line D3-D3. Figure 49B yes Figure 49A The diagram shows the structure in its closed state. Figure 46 The position of D3-D3 corresponds to Figure 8 The position of A10-A10. The section cut along D3-D3 passes through the first fixing member 15, the second rotating member 112 of the first connecting assembly 11, the first support member 104, the second mounting member 1013 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105 and the second fixing member 16.

[0346] In some embodiments, one end of the second rotating member 112 of the first connecting assembly 11 is rotatably connected to the rotating shaft assembly 10, and the other end is slidably connected to the first fixing member 15.

[0347] In this embodiment, the third arcuate arm 1121 of the second rotating member 112 of the first connecting assembly 11 is mounted in the third mounting space 10123 of the rotating shaft assembly 10, so as to rotatably connect the rotating shaft assembly 10 through a virtual shaft connection. It is understood that the second rotating member 112 can also rotatably connect the rotating shaft assembly 10 through a physical shaft connection, and this application does not strictly limit this.

[0348] The third arc-shaped arm 1121 extends into the second opening 10127 through the third mounting space 10123 to define the relative position of the third arc-shaped arm 1121 and the pivot assembly 10 along the axial direction, so as to stabilize the structure of the folding assembly 1.

[0349] The third sliding groove 1124 of the second rotating member 112 engages with the first sliding groove 1506 of the first main fixing plate 150 of the first fixing member 15, allowing the first rotating member 111 to slide relative to the first fixing member 15. Specifically, the upper sidewall 1506a of the first sliding groove 1506 is embedded in the guide space of the third sliding groove 1124, and the lower sidewall 1124b of the third sliding groove 1124 is embedded in the guide space of the first sliding groove 1506. That is, the first sliding groove 1506 and the third sliding groove 1124 are staggered and matched, which improves the connection strength between the first sliding groove 1506 and the third sliding groove 1124, and thus improves the connection strength between the second rotating member 112 and the first fixing member 15, and improves the structural stability of the folding assembly 1. In addition, the third sliding grooves 1124 on both sides of the second rotating member 112 are slidably connected to the first sliding groove 1506 of the first fixing member 15 (see...). Figure 44 This makes the sliding between the first fixing member 15 and the second rotating member 112 of the first connecting assembly 11 smoother.

[0350] Please refer to the following: Figure 46 , Figure 50A and Figure 50B , Figure 50A yes Figure 46 The diagram shows a cross-sectional view of the assembled structure taken along line D4-D4. Figure 50B yes Figure 50A The diagram shows the structure in its closed state. Figure 46 The position of D4-D4 corresponds to Figure 8 The position of A11-A11. The section cut along D4-D4 passes through the first fixing member 15, the first support member 104, the second mounting member 1013 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the fourth rotating member 122 of the second connecting assembly 12, and the second fixing member 16.

[0351] In some embodiments, one end of the fourth rotating member 122 of the second connecting assembly 12 is rotatably connected to the rotating shaft assembly 10, and the other end is slidably connected to the second fixing member 16.

[0352] In this embodiment, the third arcuate arm 1221 of the fourth rotating member 122 of the second connecting assembly 12 is installed in the fourth mounting space 10124 of the rotating shaft assembly 10 to rotatably connect to the rotating shaft assembly 10 via a virtual shaft connection. It is understood that the fourth rotating member 122 can also rotatably connect to the rotating shaft assembly 10 via a physical shaft connection, and this application does not strictly limit this.

[0353] The third arc-shaped arm 1221 extends into the third opening 10128 through the fourth mounting space 10124 to define the relative position of the third arc-shaped arm 1221 and the pivot assembly 10 along the axial direction, so as to stabilize the structure of the folding assembly 1.

[0354] Specifically, the sixth sliding groove 1224 of the fourth rotating member 122 engages with the second sliding groove 1606 of the second main fixing plate 160 of the second fixing member 16, allowing the fourth rotating member 122 to slide relative to the second fixing member 16. The upper sidewall 1606a of the second sliding groove 1606 is embedded in the guide space of the sixth sliding groove 1224, and the lower sidewall 1224b of the sixth sliding groove 1224 is also embedded in the guide space of the second sliding groove 1606. This staggered engagement of the second sliding groove 1606 and the sixth sliding groove 1224 enhances the connection strength between them, thereby increasing the connection strength between the fourth rotating member 122 and the second fixing member 16, and improving the structural stability of the folding assembly 1. Furthermore, the sixth sliding grooves 1224 on both sides of the fourth rotating member 122 are slidably connected to the second sliding grooves 1606 of the second fixing member 16, making the sliding between the second fixing member 16 and the fourth rotating member 122 of the second connecting assembly 12 smoother.

[0355] Please refer to the following: Figures 47A to 50B ,like Figure 47A , Figure 48A , Figure 49A and Figure 50A As shown, in the open state, the first arc-shaped arm 1111 of the first rotating member 111 rotates into the first mounting space 10121 of the rotating shaft assembly 10, the first arc-shaped arm 1211 of the third rotating member 121 rotates into the second mounting space 10122 of the rotating shaft assembly 10, the third arc-shaped arm 1121 of the second rotating member 112 rotates into the third mounting space 10123 of the rotating shaft assembly 10, and the third arc-shaped arm 1221 of the fourth rotating member 122 rotates into the fourth mounting space 10124 of the rotating shaft assembly 10. The first fixing member 15 and the second fixing member 16 are flattened relative to the rotating shaft assembly 10. Figure 47B , Figure 48B , Figure 49B and Figure 50BAs shown, in the closed state, the first arc-shaped arm 1111 of the first rotating member 111 slides out of the first mounting space 10121, and the first arc-shaped arm 1211 of the third rotating member 121 slides out of the second mounting space 10122. The first rotating member 111 and the third rotating member 121 are unfolded relative to the rotating shaft assembly 10 and move away from the rotating shaft assembly 10. The third arc-shaped arm 1121 of the second rotating member 112 slides out of the third mounting space 10123, and the third arc-shaped arm 1221 of the fourth rotating member 122 slides out of the fourth mounting space 10124. The second rotating member 112 and the fourth rotating member 122 are unfolded relative to the rotating shaft assembly 10 and move away from the rotating shaft assembly 10. The first fixing member 15 and the second fixing member 1... The first fixing member 15 slides relative to the first rotating member 111 and the second rotating member 112, and slides relative to the first rotating member 111 and the second rotating member 112 towards the rotating member 10, that is, the first fixing member 15 slides relative to the first rotating member 111 and the second rotating member 112 towards the rotating member 10; the second fixing member 16 slides relative to the third rotating member 121 and the fourth rotating member 122, and slides relative to the third rotating member 121 and the fourth rotating member 122 towards the rotating member 10, that is, the second fixing member 16 slides relative to the second connecting member 12 towards the rotating member 10.

[0356] Please refer to the following: Figure 46 , Figure 51A and Figure 51B , Figure 51A yes Figure 46 The diagram shows a cross-sectional view of the assembled structure taken along line D5-D5. Figure 51B yes Figure 51A The diagram shows the structure in its closed state. The cross-section along D5-D5 passes through the first fixing member 15, the first damping member 113 of the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the rotating shaft assembly 10, the first main support plate 1011 of the rotating shaft assembly 10, the second support member 105, the second damping member 123 of the second connecting assembly 12, and the second fixing member 16.

[0357] For example, the second damping member 123 may include a bracket 1233 and an elastic member 1234. The bracket 1233 includes a proximal end 1233a and a distal end 1233b disposed opposite to each other. The proximal end 1233a of the bracket 1233 may include a sleeve 1231 and a rotating shaft 1232. The distal end 1233b of the bracket 1233 and the elastic member 1234 are mounted in the first receiving groove 1214. One end of the elastic member 1234 is connected to the distal end 1233b of the bracket 1233, and the other end contacts or abuts against the groove wall of the first receiving groove 1214.

[0358] For example, the distal end 1133b of the bracket 1133 is slidably connected to the first rotating member 111, and the proximal end 1133a of the bracket 1133 extends from the first sliding groove 1115 and slides along the first sliding groove 1115. The sleeve 1131 of the proximal end 1133a of the bracket 1133 can contact or abut against the limiting member 1015 of the first main support plate 1011 of the rotating shaft assembly 10, and the sleeve 1131 can slide relative to the limiting member 1015 to reduce the frictional resistance between the first damping member 113 and the limiting member 1015. For example, the distal end 1233b of the bracket 1233 is slidably connected to the third rotating member 121, and the sleeve 1231 of the proximal end 1233a of the bracket 1233 can contact or abut against the limiting member 1015 of the first main support plate 1011 of the rotating shaft assembly 10.

[0359] Specifically, in the open state, the limiting member 1015 of the first main support plate 1011 of the pivot assembly 10 abuts against the proximal end 1133a of the bracket 1133 of the first damping member 113, and the elastic member 1134 is compressed, generating an elastic force. In the closed state, there is a gap between the limiting member 1015 of the first main support plate 1011 of the pivot assembly 10 and the proximal end 1133a of the bracket 1133 of the first damping member 113, and there is no force between them.

[0360] During the process of the electronic device 1000 moving from a closed state to an open state, the first connecting component 11 and the second connecting component 12 unfold relative to each other and slide towards the main shaft 100. The proximal end 1133a of the bracket 1133 of the first damping member 113 abuts against the limiting member 1015 of the first main support plate 1011 of the rotating shaft assembly 10. The limiting member 1015 pushes the distal end 1133b of the bracket 1133 to move away from the rotating shaft assembly 10, and the elastic member 1134 is compressed so that the first rotating member 111 of the first connecting component 11 passes the limiting member 1015 and continues to move towards the main shaft 100. The elastic force generated by the elastic member 1134 increases the friction between the proximal end 1133a and the limiting member 1015, thereby providing damping force during the rotation of the first rotating member 111 relative to the rotating shaft assembly 10. The proximal end 1233a of the bracket 1233 of the second damping member 123 abuts against the limiting member 1015 of the first main support plate 1011 of the rotating shaft assembly 10. The limiting member 1015 pushes the distal end 1233b of the bracket 1233 away from the rotating shaft assembly 10, and the elastic member 1234 is compressed, so that the third rotating member 121 of the second connecting assembly 12 passes the limiting member 1015 and continues to move towards the main shaft 100. The elastic force generated by the elastic member 1234 increases the friction between the proximal end 1233a and the limiting member 1015. Therefore, the friction between the proximal end 1133a of the bracket 1133 of the first damping member 113 and the proximal end 1233a of the bracket 1233 of the second damping member 123 and the limiting member 1015 forms a damping force, so that the first connecting assembly 11 and the second connecting assembly 12 require a certain driving force to move relative to each other. In short, the first damping element 113 can provide damping force to the movement of the first connecting component 11 relative to the rotating shaft assembly 10, and the second damping element 123 can provide damping force to the movement of the second connecting component 12 relative to the rotating shaft assembly 10, providing a damping feel.

[0361] Understandably, the connection structure between the third connecting component 13 and the fourth connecting component 14 and the rotating shaft component 10 can be referenced from the first connecting component 11 and the second connecting component 12, and will not be described again here.

[0362] In this application, multiple connecting components (11, 12, 13, 14) deform with the rotating shaft assembly 10, thereby unfolding and folding relative to each other, and driving the first shielding member 17 and the second shielding member 18 to move relative to the rotating shaft assembly 10. The following will describe how the multiple connecting components (11, 12, 13, 14) drive the first shielding member 17 and the second shielding member 18 to move relative to the rotating shaft assembly 10.

[0363] Please refer to the following: Figure 7 , Figure 41 and Figure 52A , Figure 52A yes Figure 41 The diagram shows the structure of the first slider 110 at another angle. Figure 52A The viewpoint shown is relative to Figure 41 The view shown has been flipped left and right.

[0364] The folding assembly 1 may further include a first slider 110 and a second slider 120. The upper side of the first slider 110 may be fixedly connected to the first shielding member 17, and the lower side of the first slider 110 may be slidably connected to the first rotating member 111 and the second rotating member 112. The upper side of the second slider 120 is fixedly connected to the second shielding member 18, and the lower side of the second slider 120 is slidably connected to the third rotating member 121 and the fourth rotating member 122. The first shielding member 17 slides relative to the first rotating member 111 as the first slider 110 moves, meaning the first shielding member 17 can be slidably connected to the first rotating member 111. The second shielding member 18 slides relative to the third rotating member 121 as the second slider 120 moves, meaning the second shielding member 18 is slidably connected to the third rotating member 121.

[0365] In this embodiment, the first shielding member 17 can be slidably connected to the first connecting component 11 via the first sliding member 110, and the second shielding member 18 can be slidably connected to the second connecting component 12 via the second sliding member 120, which facilitates the maintenance and replacement of the first shielding member 17 and the second shielding member 18 and reduces costs.

[0366] In some other embodiments, the folding assembly 1 may not include the first slider 110 and the second slider 120, the first shielding member 17 may be directly slidably connected to the first connecting assembly 11 without the first slider 110, or may be slidably connected to the first connecting assembly 11 through other structures; and / or the second shielding member 18 may be directly slidably connected to the second connecting assembly 12 without the second slider 120, or may be slidably connected to the second connecting assembly 11 through other structures. This application does not limit the scope of these embodiments.

[0367] For example, the first sliding member 110 may include a first sliding plate 1101, a plurality of sliding mating parts (1102, 1103, 1104), and a plurality of actuating parts (1105, 1106). The plurality of sliding mating parts (1102, 1103, 1104) are spaced apart at the top, middle, and bottom of the first sliding plate 1101. Each of the sliding mating parts (1102, 1103, 1104) may include an arc-shaped arm for engaging with the sliding grooves of the first rotating member 111 and the second rotating member 112, allowing the first sliding member 110 to slide relative to the first rotating member 111 and the second rotating member 112. For example, the arc-shaped arm bends to form a sliding space, which can accommodate the upper groove wall of the sliding groove of the first rotating member 111 and the second rotating member 112, and the end of the arc-shaped arm can extend into the sliding groove. The arc-shaped arm and the upper groove wall of the sliding groove engage with each other to form a sliding structure. The plurality of sliding mating parts (1102, 1103, 1104) may include a first sliding mating part 1102, a second sliding mating part 1103, and a third sliding mating part 1104. The first sliding mating part 1102 includes a first arc-shaped arm 1102a, and the second sliding mating part 1103 includes a second arc-shaped arm 1103a. The openings of the first arc-shaped arm 1102a and the second arc-shaped arm 1103a are opposite to each other. The first arc-shaped arm 1102a and the second arc-shaped arm 1103a respectively mate with the second sliding grooves 1117 on both sides of the first rotating member 111. The third sliding mating part 1104 includes a third arc-shaped arm 1104a, which is used to mate with the third sliding groove 1124 of the second rotating member 112. The first arc-shaped arm 1102a, the second arc-shaped arm 1103a, and the third arc-shaped arm 1104a all extend in a direction away from the rotating shaft assembly 10, and the extending directions are parallel to each other. This application utilizes a first arc-shaped arm 1102a and a second arc-shaped arm 1103a to engage with the sliding groove of the first rotating member 111, and a third arc-shaped arm 1104a to engage with the sliding groove of the second rotating member 112, to ensure stable and reliable sliding of the first sliding member 110 relative to the first connecting assembly 11. Understandably, the first sliding member 110 may also include only the first arc-shaped arm 1102a or the second arc-shaped arm 1103a to simplify the structure of the sliding member 10. In some other embodiments, the number of third arc-shaped arms 1104a may also be two to increase the connection strength between the first sliding member 110 and the second rotating member 112.

[0368] Among them, a plurality of actuating elements (1105, 1106) protrude from the lower surface of the first sliding plate 1101. The plurality of actuating elements (1105, 1106) includes a first actuating element 1105 and a second actuating element 1106. The first actuating element 1105 is at least partially located in the second receiving groove 1116 of the first rotating element 111, and is used to actuate the first elastic element 114 installed in the second receiving groove 1116. The second actuating element 1106 is at least partially located in the third receiving groove 1122 of the second rotating element 112, and is used to actuate the second elastic element 115 installed in the third receiving groove 1122.

[0369] Please refer to the following: Figure 7 , Figure 41 , Figure 45A and Figure 52B , Figure 52B yes Figure 7 A schematic diagram of the structure of the second slider 120 of the second connecting component 12 at another angle.

[0370] For example, the second slider 120 may include a first sliding plate 1201, a plurality of sliding mating parts (1202, 1203, 1204), and a plurality of actuating parts (1205, 1206). The plurality of sliding mating parts (1202, 1203, 1204) are spaced apart at the top, middle, and bottom of the first sliding plate 1201. Each sliding mating part (1202, 1203, 1204) may include an arc-shaped arm for engaging with the grooves of the third rotating part 121 and the fourth rotating part 122, so that the second slider 120 slides relative to the third rotating part 121 and the fourth rotating part 122.

[0371] Among them, a plurality of actuating elements (1205, 1206) protrude from the lower surface of the first sliding plate 1101. The plurality of actuating elements (1205, 1206) includes a first actuating element 1205 and a second actuating element 1206. The first actuating element 1205 is at least partially located in the second receiving groove 1216 of the third rotating element 121, and is used to actuate the first elastic element 124 installed in the second receiving groove 1216. The second actuating element 1206 is at least partially located in the third receiving groove 1222 of the fourth rotating element 122, and is used to actuate the second elastic element 125 installed in the third receiving groove 1222.

[0372] Understandably, the structure of the second slider 120 of the second connecting component 12 can be referenced to the first slider 110 of the first connecting component 11, and will not be described again here.

[0373] For example, such as Figure 52AAs shown, the upper side of the first sliding plate 1101 may be provided with a groove. The first shielding member 17 can be fixed to the upper surface of the groove wall of the first sliding plate 1101 of the first sliding member 110, reducing the fixing area between the first shielding member 17 and the first sliding member 110, facilitating the separation of the first shielding member 17 and the first sliding member 110, thereby benefiting the maintenance and replacement of the first shielding member 17. In some other embodiments, the upper side of the first sliding plate 1101 may not be provided with a groove, that is, the upper surface of the first sliding member 110 is a plane, so as to increase the fixing area between the first shielding member 17 and the first sliding member 110 and improve the connection strength. In addition, the first shielding member 17 and the first sliding member 110 can be fixed by means of gluing, riveting, etc., which is not limited in this application. Understandably, the fixing method of the second shielding member 18 and the second sliding member 120 can refer to the fixing method of the first shielding member 17 and the first sliding member 110, and will not be described again here. The fixing method of the second shielding member 18 and the second sliding member 120 can be the same as or different from the fixing method of the first shielding member 17 and the first sliding member 110. This application does not limit this.

[0374] Please refer to the following: Figure 41 , Figure 52A and Figure 53 , Figure 53 yes Figure 52A The first slider 110 shown and Figure 41 The diagram shows the assembly structure of the first connecting component 11.

[0375] In some embodiments, the first arcuate arm 1102a and the second arcuate arm 1103a of the first slider 110 respectively engage with the second sliding grooves 1117 on both sides of the first rotating member 111, so that the first slider 110 is slidably connected to the first rotating member 111; in addition, the third arcuate arm 1104a engages with the third sliding groove 1124 of the second rotating member 112, so that the first slider 110 is slidably connected to the second rotating member 112. Therefore, the first slider 110 is slidably connected to the first rotating member 111 and the second rotating member 112, that is, the first slider 110 is slidably connected to the first connecting assembly 11.

[0376] For example, the first arc-shaped arm 1102a forms a guide space, and the upper sidewall 1117a of the second sliding groove 1117 is installed in the guide space of the first arc-shaped arm 1102a, so that the first sliding member 110 is slidably connected to the first rotating member 111. The third arc-shaped arm 1104a forms a guide space, and the upper sidewall 1124a of the third sliding groove 1124 is installed in the guide space of the third arc-shaped arm 1104a, so that the first sliding member 110 is slidably connected to the second rotating member 112. In some other embodiments, the first sliding member 110 may also be slidably connected to the first rotating member 111 and / or the second rotating member 112 by other structures, such as guide rails, etc., which are not limited in this application.

[0377] In this application, the second slider 120 is slidably connected to the second connecting component 12, and the connection relationship between the second slider 120 and the second connecting component 12 can be referred to the connection relationship between the first slider 110 and the first connecting component 11, which will not be repeated here.

[0378] Please refer to the following: Figure 7 , Figure 53 , Figure 54A and Figure 54B , Figure 54A yes Figure 6 The diagram shows a cross-sectional view of the folding component 1 taken along line E1-E1. Figure 54B yes Figure 54A The diagram shows the structure in its closed state. Figure 6 The position of E1-E1 in the middle corresponds to Figure 46 The section cut along E1-E1 from position D1-D1 passes through the first shielding member 17, the first fixing member 15, the first rotating member 111 of the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the third rotating member 121 of the second connecting assembly 12, the second fixing member 16, and the second shielding member 18.

[0379] In some embodiments, the first shielding member 17 may be fixedly connected to the first sliding member 110 (see [link]). Figure 54A And the first slider 110 is slidably connected to the first connecting assembly 11 (see [link]). Figure 53 Therefore, the first shielding member 17 slides relative to the first connecting assembly 11 as the first sliding member 110 moves, that is, the first shielding member 17 is slidably connected to the first connecting assembly 11; the second shielding member 18 is fixedly connected to the second sliding member 120 (see [link]). Figure 54A The second slider 120 is slidably connected to the second connecting assembly 12 (see [link]). Figure 53Therefore, the second shielding member 18 slides relative to the second connecting component 12 as the second sliding member 120 moves, that is, the second shielding member 18 is slidably connected to the second connecting component 12.

[0380] In some embodiments, the first actuating member 1105 of the first sliding member 110 is placed in the second receiving groove 1116 of the first rotating member 111 and is opposite to the insertion member 1113 of the second receiving groove 1116. The two ends of the first elastic member 114 contact or abut against the first actuating member 1105 and the insertion member 1113 of the second receiving groove 1116, that is, the two ends of the first elastic member 114 contact or abut against the first actuating member 1105 and the second receiving groove 1116. The first elastic member 114 connects the first sliding member 110 and the first rotating member 111, that is, the first elastic member 114 connects the first shielding member 17 and the first rotating member 111. The first elastic member 114 is used to provide a first elastic force, which drives the first shielding member 17 to slide relative to the first rotating member 111 towards the direction of the rotating shaft assembly 10.

[0381] In this design, the first actuating member 1205 of the second sliding member 120 is positioned in the second receiving groove 1216 of the third rotating member 121 and is opposite to the insertion member 1213 of the second receiving groove 1216. Both ends of the first elastic member 124 contact or abut against the first actuating member 1205 and the insertion member 1213 of the second receiving groove 1216. The second sliding member 120 deforms and generates an elastic force by pressing the first elastic member 124 with the first actuating member 1205. The first elastic member 124 connects the second sliding member 120 and the third rotating member 121, i.e., it connects the second shielding member 18 and the third rotating member 121. The first elastic member 124 provides a second elastic force, which drives the second shielding member 18 to slide relative to the third rotating member 121 towards the rotating shaft assembly 10.

[0382] In the open state, the second shielding member 18 of the first shielding member 17 is relatively flattened, and the first shielding member 17 contacts or abuts the second shielding member 18 to achieve positioning. The first connecting assembly 11 and the second connecting assembly 12 are substantially flattened relative to the rotating shaft assembly 10. The first actuating member 1105 of the first sliding member 110 is located at the far-axis end 1116a of the second receiving groove 1116 of the first rotating member 111, and the first actuating member 1205 of the second sliding member 120 is located at the far-axis end 1216a of the second receiving groove 1216 of the third rotating member 121.

[0383] In the closed state, the first shielding member 17 and the second shielding member 18 are folded relative to each other, the first connecting assembly 11 and the second connecting assembly 12 are folded relative to the pivot assembly 10, the first actuating member 1105 of the first slider 110 is located in the middle of the second receiving groove 1116, and the first elastic member 114 is compressed, generating a first elastic force. The first actuating member 1205 of the second slider 120 is located in the middle of the second receiving groove 1216, and the first elastic member 124 is compressed, generating a second elastic force.

[0384] During the movement of the folding assembly 1, that is, during the movement of the electronic device 1000, the first connecting assembly 11 and the first shielding member 17 rotate relative to the main shaft 100, and the second connecting assembly 12 and the second shielding member 18 rotate relative to the main shaft 100.

[0385] Specifically, during the process of the folding assembly 1 moving from the open state to the closed state, that is, during the process of the electronic device 1000 moving from the open state to the closed state, the first shielding member 17 and the second shielding member 18 fold relative to each other, the main shaft 100 presses the first shielding member 17 and the second shielding member 18, the first shielding member 17 slides relative to the first connecting assembly 11 in a direction away from the main shaft 100, and the first sliding member 110 also slides in a direction away from the main shaft 100, so that the first actuating member 1105 of the first sliding member 110 moves from the first rotating member 111... The distal end 1116a of the second receiving groove 1116 moves toward the proximal end 1116b, compressing the first elastic member 114 and generating a first elastic force; the second shielding member 18 slides relative to the second connecting assembly 12 away from the main shaft 100, and the second sliding member 120 also slides away from the main shaft 100, so that the first actuating member 1205 of the second sliding member 120 moves from the distal end 1216a of the second receiving groove 1216 of the third rotating member 121 toward the proximal end 1216b, compressing the first elastic member 124 and generating a second elastic force.

[0386] During the process of the folding assembly 1 moving from the closed state to the open state, that is, during the process of the electronic device 1000 moving from the closed state to the open state, the first shielding member 17 and the second shielding member 18 unfold relative to each other. Under the action of the first elastic force of the first elastic member 114, the first sliding member 110 slides relative to the first connecting assembly 11 towards the main shaft 100, and drives the first shielding member 17 to slide relative to the first connecting assembly 11 towards the main shaft 100. Under the action of the second elastic force of the first elastic member 124, the second sliding member 120 slides relative to the second connecting assembly 12 towards the main shaft 100, and drives the second shielding member 18 to slide relative to the second connecting assembly 12 towards the main shaft 100. That is, the first shielding member 17 and the second shielding member 18 contact or abut against each other under the action of the elastic force of the elastic members (114, 124) to shield and protect the main shaft 100.

[0387] In some other embodiments, the folding assembly 1 may not have the first sliding member 110, the first shielding member 17 may be slidably connected to the first connecting assembly 11 without the first sliding member 110, and the first elastic member 114 may be directly connected to the first shielding member 17 and the first rotating member 111 without the first sliding member 110. Exemplarily, the first shielding member 17 may have a sliding engagement structure and a toggle member similar to the first sliding member 110, or it may have other structures, which are not limited in this application.

[0388] For example, in the open state, the first elastic member 114 can abut against the first actuating member 1105, providing a pushing force toward the main shaft 100 to the first shielding member 17; and / or the first elastic member 124 can abut against the first actuating member 1205, providing a pushing force toward the main shaft 100 to the second shielding member 18. The first shielding member 17 and the second shielding member 18 abut against each other under the action of the pushing force, so as to reduce the gap between the first shielding member 17 and the second shielding member 18 and improve the shielding and protection effect. In some other embodiments, the first elastic member 114 can also contact the first actuating member 1105, and the first elastic member 124 can also contact the first actuating member 1205.

[0389] For example, when the electronic device 1000 is in the open state, the first shielding member 17 and the second shielding member 18 are joined together to achieve positioning. In this application, the contact between the first shielding member 17 and the second shielding member 18 can be considered as "joining", and the first shielding member 17 and the second shielding member 18 being close to each other with a tiny gap between them can also be considered as "joining". External impurities, such as stones or metal parts, cannot enter the interior of the electronic device 1000 through the tiny gap. This application does not limit this.

[0390] Please refer to the following: Figure 7 , Figure 55A and Figure 55B , Figure 55A yes Figure 6 The diagram shows a cross-sectional view of the folding component 1 taken along line E2-E2. Figure 55B yes Figure 55A The diagram shows the structure in its closed state. Figure 6 The position of E2-E2 corresponds to Figure 46 The section cut along E2-E2 at position D3-D3 passes through the first shielding member 17, the first fixing member 15, the second rotating member 112 of the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the second connecting assembly 12, the second fixing member 16, and the second shielding member 18.

[0391] In some embodiments, the second actuating member 1106 of the first sliding member 110 of the first connecting assembly 11 is placed in the third receiving groove 1122 of the second rotating member 112 and opposite to the insertion member 1123 of the third receiving groove 1122. The two ends of the second elastic member 115 abut against the second actuating member 1106 and the insertion member 1123 of the third receiving groove 1122, that is, the two ends of the second elastic member 115 abut against the second actuating member 1106 and the third receiving groove 1122. The second elastic member 115 connects the first sliding member 110 and the second rotating member 112, and the second elastic member 115 is used to provide a third elastic force, which drives the first shielding member 17 to slide relative to the second rotating member 112 towards the main shaft 100.

[0392] Please refer to the following: Figure 7 , Figure 56A and Figure 56B , Figure 56A yes Figure 6 The diagram shows a cross-sectional view of the folding component 1 taken along line E3-E3. Figure 56B yes Figure 56A The diagram shows the structure in its closed state. Figure 6 The position of E3-E3 corresponds to Figure 46 The section cut along E3-E3 at position D4-D4 passes through the first shielding member 17, the first fixing member 15, the first connecting assembly 11, the first support member 104, the first mounting member 1012 of the top shaft 101, the first main support plate 1011 of the top shaft 101, the second support member 105, the fourth rotating member 122 of the second connecting assembly 12, the second fixing member 16, and the second shielding member 18.

[0393] In some embodiments, the second actuating member 1206 of the second sliding member 120 of the second connecting assembly 12 is positioned in the third receiving groove 1222 of the fourth rotating member 122 and opposite to the insertion member 1123 of the third receiving groove 1222. The two ends of the second elastic member 125 abut against the second actuating member 1206 and the insertion member 1123 of the third receiving groove 1222; that is, the two ends of the second elastic member 125 abut against the second actuating member 1206 and the third receiving groove 1222. The second elastic member 125 connects the second sliding member 120 and the fourth rotating member 122, providing a fourth elastic force that drives the second shielding member 18 to slide relative to the fourth rotating member 122 towards the main shaft 100.

[0394] Please refer to the following: Figures 55A to 56BIn the open state, the first shielding member 17 and the second shielding member 18 are relatively flattened. The second actuating member 1106 of the first sliding member 110 is located at the far-axis end 1122a of the third receiving groove 1122 of the second rotating member 112, and the second actuating member 1206 of the second sliding member 120 is located at the far-axis end 1222a of the third receiving groove 1222 of the fourth rotating member 122.

[0395] In the closed state, the first shielding member 17 and the second shielding member 18 are folded relative to each other. The second actuating member 1106 of the first sliding member 110 is located in the middle of the third receiving groove 1122, and the second elastic member 115 is compressed, generating a third elastic force. The second actuating member 1206 of the second sliding member 120 is located in the middle of the third receiving groove 1222, and the second elastic member 125 is compressed, generating a fourth elastic force.

[0396] During the process of moving from the open state to the closed state, the first shielding member 17 rotates relative to the main shaft 100 with the first connecting assembly 11 and slides away from the main shaft 100 relative to the third rotating member 121 under the compression of the main shaft 100. The first sliding member 110 also slides away from the main shaft 100. The second actuating member 1106 of the first sliding member 110 moves from the far-axis end 1122a to the near-axis end 1122b of the third receiving groove 1122 of the third rotating member 121. The second elastic member 115 is compressed, generating a third elastic force. The second shielding member 18 rotates relative to the main shaft 100 with the second connecting assembly 12 and slides away from the main shaft 100 relative to the fourth rotating member 122 under the pressure of the main shaft 100. The second shielding member 18 slides away from the main shaft 100 under the pressure of the main shaft 100, and the second sliding member 120 also slides away from the main shaft 100. The first actuating member 1205 of the second sliding member 120 moves from the far-axis end 1222a to the near-axis end 1222b of the third receiving groove 1222 of the fourth rotating member 122. The second elastic member 125 is compressed, generating a fourth elastic force.

[0397] During the process of moving from the closed state to the open state, the first shielding member 17 and the second shielding member 18 unfold relative to each other. The first sliding member 110 moves towards the main shaft 100 under the action of the third elastic force of the second elastic member 115, and drives the first shielding member 17 to move towards the main shaft 100. The second sliding member 120 moves towards the main shaft 100 under the action of the fourth elastic force of the second elastic member 125, and drives the second shielding member 18 to move towards the main shaft 100. That is, the first shielding member 17 and the second shielding member 18 come into contact with or abut against each other under the action of the elastic force of the elastic members (115, 125) to shield and protect the internal structure of the electronic device 1000.

[0398] For example, in the open state, the second elastic member 115 can abut against the second actuating member 1106, providing a pushing force toward the main shaft 100 to the first shielding member 17; and / or the second elastic member 125 can abut against the second actuating member 1206, providing a pushing force toward the main shaft 100 to the second shielding member 18. The first shielding member 17 and the second shielding member 18 abut against each other under the action of the pushing force, thereby reducing the gap between the first shielding member 17 and the second shielding member 18 and improving the shielding and protection effect. In some other embodiments, the second elastic member 115 can also contact the second actuating member 1106, and the second elastic member 125 can also contact the second actuating member 1206.

[0399] Please refer to the following: Figures 54A to 56B In this application, during the rotation of the first connecting component 11 and the second connecting component 12 relative to the main shaft 100, the first sliding member 110 slides relative to the first rotating member 111 and the second rotating member 112 as the first connecting component 11 rotates, and the second sliding member 120 slides relative to the third rotating member 121 and the fourth rotating member 122 as the second connecting component 12 rotates, thereby causing the first shielding member 17 and the second shielding member 18 to unfold and fold relative to each other.

[0400] Specifically, during the movement from the open state to the closed state, the first shielding member 17 and the second shielding member 18 slide away from the main shaft 100 under the pressure of the main shaft 100. The first sliding member 110 and the second sliding member 120 also slide away from the main shaft 100, compressing the elastic members (114, 115, 124, 125) and generating elastic force. During the movement from the closed state to the open state, the first shielding member 17 and the second shielding member 18 unfold relative to each other. The first sliding member 110 and the second sliding member 120 move towards the main shaft 100 under the action of the elastic force of the elastic members (114, 115, 124, 125), and drive the first shielding member 17 and the second shielding member 18 to move towards the main shaft 100, so that the first shielding member 17 and the second shielding member 18 come into contact with or abut against each other, thereby shielding and protecting the internal structure of the electronic device 1000.

[0401] For example, please refer to the following: Figure 45ABecause the rotation center of the second rotating member 112 of the first connecting assembly 11 relative to the main shaft 100 coincides with the rotation center of the first rotating member 111 of the first connecting assembly 11 relative to the main shaft 100, the sliding of the first sliding member 110 relative to the first connecting assembly 11 is smooth and reliable, thereby ensuring smooth and reliable movement of the first shielding member 17 relative to the main shaft 100. Furthermore, because the rotation center of the fourth rotating member 122 of the second connecting assembly 12 relative to the main shaft 100 coincides with the rotation center of the third rotating member 121 of the second connecting assembly 12 relative to the main shaft 100, the sliding of the second sliding member 120 relative to the first connecting assembly 11 is smooth and reliable, thereby ensuring smooth and reliable movement of the second shielding member 18 relative to the main shaft 100. Therefore, in this application, the relative movement of the first shielding member 17 and the second shielding member 18 is smooth and reliable.

[0402] For example, the implementation of the third slider 130 connecting the first shielding member 17 and the third connecting component 13 can refer to the structure of the first slider 110 connecting the first shielding member 17 and the first connecting component 11, and the implementation of the fourth slider 140 connecting the second shielding member 18 and the fourth connecting component 14 can refer to the structure of the second slider 120 connecting the second shielding member 18 and the second connecting component 12, which will not be described again here.

[0403] The connection structure of the first rear cover 21, the second rear cover 31, the first middle frame 22, the second middle frame 32 and the folding assembly 1 is described below with reference to the accompanying drawings.

[0404] Please refer to the following: Figure 6 , Figure 57A and Figure 57B , Figure 57A yes Figure 5 The diagram shows the internal structure of a portion of the electronic device 1000. Figure 57B yes Figure 57A The diagram shows the structure in its closed state.

[0405] In some embodiments, the first rear cover 21, the second rear cover 31, and the first shielding member 17 and the second shielding member 18 of the folding assembly 1 together constitute part of the exterior components of the electronic device 1000, providing protection for the internal structure of the electronic device 1000 and shielding the internal structure of the electronic device 1000, thus making the electronic device 1000 aesthetically pleasing. The folding assembly 1 connects the first middle frame 22 and the second middle frame 32, and the first middle frame 22 and the second middle frame 32 can be relatively unfolded or folded relative to each other as the folding assembly 1 deforms. The first rear cover 21 and the second rear cover 31 can be relatively unfolded or folded relative to each other as the first middle frame 22 and the second middle frame 32 move. Furthermore, the first shielding member 17 and the second shielding member 18 can be located above or below the first rear cover 21 and the second rear cover 31, that is, the first rear cover 21 and the second rear cover 31 are arranged in parallel, the first shielding member 17 and the second shielding member 18 are arranged in parallel, and the first rear cover 21 and the first shielding member 17 are staggered, so that when the first housing 2 and the second housing 3 are folded to a closed state, the first shielding member 17 can overlap with part of the structure of the first rear cover 21, and the second shielding member 18 can overlap with part of the structure of the second rear cover 31, so as to reduce the space occupied by the shielding member when the housing device 300 is folded, and the structure of the electronic device 1000 is compact.

[0406] This application will be described using the example of the first shielding member 17 and the second shielding member 18 being located on the underside of the first rear cover 21 and the second rear cover 31. For example... Figure 57A As shown, in the open state, the first rear cover 21 and the second rear cover 31 are relatively flattened, and together with the first shielding member 17 and the second shielding member 18, they form an exterior component, shielding the internal structure of the electronic device 1000. Figure 57B As shown, when the first housing 2 and the second housing 3 are folded to a closed state, the first shielding member 17 and the second shielding member 18 are unfolded relative to each other under the compression of the main shaft 100, and the first shielding member 17 is at least partially folded into the inner side of the first rear cover 21, that is, the first shielding member 17 is at least partially folded into the first housing 2, and the second shielding member 18 is at least partially folded into the inner side of the second rear cover 31, that is, the second shielding member 18 is at least partially folded into the second housing 3, so as to reduce the space occupied by the shielding members.

[0407] The proximal end 21a of the first rear cover 21 overlaps with the distal end 17b of the first shielding member 17, and the proximal end 31a of the second rear cover 31 overlaps with the distal end 18b of the second shielding member 18, so that the exterior components can effectively shield the internal structure of the electronic device 1000 and improve the dustproof and waterproof performance of the electronic device 1000.

[0408] The first rear cover 21 and / or the second rear cover 31 may have a sealing element at their proximal ends 21a and 31a. For example, the sealing element may be fixed to the lower surface of the first rear cover 21 and abut against the upper surface of the first shielding member 17, or fixed to the upper surface of the first shielding member 17 and abut against the lower surface of the first rear cover 21, to fill the gap between the first rear cover 21 and the first shielding member 17. Similarly, the sealing element may be fixed to the lower surface of the second rear cover 31 and abut against the upper surface of the first shielding member 17, or fixed to the upper surface of the first shielding member 17 and abut against the lower surface of the second rear cover 31, to fill the gap between the first rear cover 21 and the first shielding member 17. The sealing element improves the sealing performance of the external components of the electronic device 1000, preventing moisture and dust from the external environment from entering the interior of the electronic device 1000 through the gap, thereby improving the reliability and service life of the electronic device 1000. For example, the seal may be made of an elastic deformable material, such as rubber or soft rubber. The elastic deformable material may have self-lubricating properties; for example, the elastic deformable material may contain 10% POM (polyformaldehyde or polyoxymethylene resin) by mass. In other embodiments, the seal may also be made of a non-elastic deformable material, which is not limited herein.

[0409] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Where there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other. Therefore, the scope of protection of this application should be determined by the scope of the claims.
