[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on June 26, 2023, with application number 202310765266.4 and application name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of terminal technology, and in particular to an electronic device. Background Art

[0003] With the explosive growth of electronic devices such as smartphones and tablets, electronic devices are becoming increasingly versatile. The varying sizes of their display screens result in varying user experiences with these functions. While the display screens of electronic devices are becoming increasingly larger, this can lead to larger overall dimensions and inconvenience in portability. Advances in display technology have enabled the manufacture of flexible display modules. These modules include flexible display screens. Compared to traditional screens, flexible display screens offer significant advantages, such as bendability and flexibility. Flexible display screens can be used in foldable electronic devices. These foldable electronic devices include a housing and a hinge assembly. The two housings can rotate relative to each other about the hinge assembly to unfold or fold. The flexible display covers the two housings. When the two housings unfold to the same plane, the flexible display is unfolded, providing a larger display area. When the two housings fold together, the flexible display is folded, and the electronic device is compact. However, during the folding or unfolding of a foldable electronic device, internal components may collide or rub, causing unusual noises and impacting the user experience.

[0004] Summary of the Invention

[0005] An embodiment of the present application provides an electronic device that can reduce the possibility of abnormal noise being generated during the folding or unfolding process of the electronic device.

[0006] A first aspect of the present application provides an electronic device comprising a flexible display screen and a hinge device.

[0007] The pivot assembly is disposed on the backlight side of the flexible display. The pivot assembly includes a shaft seat, a swing arm assembly, a door panel assembly, a metal support sheet, and an isolation gasket. The swing arm assembly includes a first swing arm and a second swing arm. The first and second swing arms are disposed on either side of the shaft seat along the width of the shaft seat. Both the first and second swing arms are rotatably connected to the shaft seat. The door panel assembly includes a first door panel and a second door panel. The first door panel is connected to the first swing arm. The second door panel is connected to the second swing arm. The metal support sheet is disposed between the door panel assembly and the flexible display. The metal support sheet includes opposing connecting ends and free ends. The connecting end is connected to the first door panel. The free end is located on the side of the second door panel facing the flexible display and is free relative to the second door panel. The isolation gasket is connected to the metal support sheet. Along the length of the shaft seat, the isolation gasket covers at least a portion of the free end. The isolation gasket isolates the second door panel from the free end.

[0008] In the electronic device of the embodiment of the present application, the metal support sheet can isolate the flexible display from the structural components of the hinge assembly, for example, isolating the flexible display from the shaft seat, swing arm assembly, and door panel assembly of the hinge assembly, thereby reducing the possibility of structural damage to the flexible display due to impact from the structural components of the hinge assembly during folding or unfolding. The metal support sheet can fold or unfold along with the door panel assembly. The metal support sheet is provided with an isolation gasket. During the folding or unfolding process of the metal support sheet, the isolation gasket moves with the metal support sheet. The isolation gasket can cover at least a portion of the free end, thereby isolating the free end from the second door panel, making contact between the free end and the second door panel less likely. Furthermore, during the folding or unfolding process of the metal support sheet, the free end is less likely to rub against the structural components of the second door panel, reducing the possibility of abnormal noise caused by direct rubbing between the free end and the structural components of the second door panel. In addition, the method of providing the isolation gasket on the metal support sheet makes the process of connecting the isolation gasket and the metal support sheet relatively simple, which helps to reduce costs.

[0009] In a possible embodiment, the isolation gasket covers the entire free end along the length direction of the shaft seat.

[0010] The isolation gasket can fully cover the free end, thereby further improving the isolation effect and helping to reduce the possibility of contact and scratching between any position of the free end and the second door panel.

[0011] In one possible embodiment, the rotating shaft device further includes a shielding piece. Along the length direction of the shaft seat, both ends of the isolation gasket are connected to the shielding piece. The shielding piece shields the free end.

[0012] The isolation gasket and the shielding sheet can jointly cover the free end to further reduce the exposed area of ​​the free end, which is conducive to further reducing the possibility of the free end being scratched against external structural parts.

[0013] In one possible embodiment, the isolation gasket includes a first connecting section, a bent connecting section, and a second connecting section. The first connecting section is disposed on the side of the metal support sheet facing the flexible display screen. The second connecting section is disposed on the side of the metal support sheet facing the second door panel. The bent connecting section connects the first and second connecting sections. The first, bent, and second connecting sections enclose a storage space. The free end is inserted into the storage space.

[0014] The structure of the isolation gasket itself is relatively simple, which helps to reduce the processing difficulty of the isolation gasket and reduce the processing cost.

[0015] In a possible embodiment, the number of the second connecting segments is more than two, and the more than two second connecting segments are spaced apart along the length direction of the shaft seat.

[0016] The configuration of the second connecting section in this embodiment is beneficial for saving the usage of isolation gaskets and reducing production costs.

[0017] In a possible implementation, the number of the bent connecting segments is more than two, and the bent connecting segments are arranged in a one-to-one correspondence with the second connecting segments.

[0018] The manner in which the bent connecting section and the second connecting section are arranged correspondingly is beneficial to further saving the usage of isolation gaskets and reducing production costs.

[0019] In a possible implementation, the number of the first connecting segments is more than two, and the first connecting segments are arranged in a one-to-one correspondence with the bent connecting segments.

[0020] The arrangement of the first connecting section is conducive to further saving the usage of isolation gaskets and reducing production costs.

[0021] In a possible implementation, along the width direction of the shaft seat, the width of the first connecting section is greater than the width of the second connecting section.

[0022] In a possible implementation, along the width direction of the shaft seat, the width of the first connecting section is smaller than the width of the second connecting section.

[0023] In a possible implementation, along the width direction of the shaft seat, the width of the first connecting section is greater than the width of the second connecting section. The first connecting section covers the entire surface of the metal support sheet facing the flexible display screen.

[0024] The first connecting section can isolate the metal support sheet and the flexible display screen, so that the first connecting section can protect the flexible display screen, which is beneficial to reducing the possibility of the metal support sheet directly scratching the flexible display screen.

[0025] In a possible implementation, a portion of the second connecting section is located between the second door panel and the metal support plate, and another portion is located between the metal support plate and the swing arm assembly and between the metal support plate and the axle seat.

[0026] The second connecting section can isolate the metal support plate from the swing arm assembly, thereby reducing the possibility of contact between the metal support plate and the swing arm assembly, which could cause scraping or abnormal noise between the two. At the same time, the second connecting section can isolate the metal support plate from the axle seat, thereby reducing the possibility of contact between the metal support plate and the axle seat, which could cause scraping or abnormal noise between the two.

[0027] In a possible implementation, the isolation gasket is a flexible gasket.

[0028] When the isolation gasket and the second door panel slide relative to each other, the isolation gasket effectively cushions the movement, reducing the possibility of unusual noises between the two panels and scratches caused by contact between the isolation gasket and the second door panel. The first connecting segment between the metal support sheet and the flexible display also acts as a buffer, ensuring flexible contact between the flexible display and the first connecting segment, further minimizing the possibility of structural damage to the flexible display.

[0029] In a possible implementation manner, the isolation gasket is an insulating gasket.

[0030] The portion of the isolation gasket located between the flexible display screen and the metal support sheet (eg, the first connecting section) can function as an insulating barrier, thereby reducing the possibility of electrical signals being transmitted between the flexible display screen and the metal support sheet through the metal support sheet.

[0031] In one possible embodiment, the free end includes an upper surface facing the flexible display screen, a lower surface facing the second door panel, and a transition surface. The transition surface connects the upper and lower surfaces. The lower surface is curved. The thickness of the free end decreases as it moves away from the connection end.

[0032] During the movement of the free end relative to the second door panel, the free end is less likely to locally squeeze the isolation gasket, thereby reducing the possibility of stress concentration on the isolation gasket causing cracks or damage to the isolation gasket.

[0033] In one possible embodiment, the transition surface is a curved surface. The lower surface, transition surface, and upper surface smoothly transition to each other, thereby eliminating sharp edges on the free end. This reduces the possibility of the sharp edge of the free end locally squeezing the isolation gasket and causing damage to the isolation gasket, thereby reducing the possibility of the isolation gasket failing due to damage and causing the free end to directly scrape the second door panel.

[0034] In a possible implementation manner, the connecting end is bonded to the first door panel.

[0035] The connecting end and the first door panel are bonded together, so that no additional connecting parts such as screws, clips or rivets are required between the connecting end and the first door panel. On the one hand, this is beneficial to reducing the complexity of the connecting structure between the connecting end and the first door panel and reducing the difficulty of assembly; on the other hand, there is no need to set a corresponding connecting structure, such as a hole, on the connecting end and the first door panel, which is beneficial to reducing the processing difficulty of the connecting end and the first door panel and improving the structural integrity of the connecting end and the first door panel.

[0036] In a possible implementation manner, the isolation gasket is bonded to the metal support sheet.

[0037] The isolation gasket and the metal support sheet are bonded together, so that no additional connecting components such as screws, clips or rivets are required between the isolation gasket and the metal support sheet. On the one hand, this helps to reduce the complexity of the connection structure between the isolation gasket and the metal support sheet and reduce the difficulty of assembly; on the other hand, there is no need to set corresponding connecting structures, such as holes, on the isolation gasket and the metal support sheet, which helps to reduce the processing difficulty of the isolation gasket and the metal support sheet and improve the structural integrity of the isolation gasket and the metal support sheet.

[0038] A second aspect of the present application provides an electronic device, which includes a flexible display screen and a hinge device.

[0039] The hinge assembly is located on the backlight side of the flexible display. The hinge assembly includes a shaft seat, a swing arm assembly, a door panel assembly, and a metal support plate. The swing arm assembly includes a first swing arm and a second swing arm. The first and second swing arms are respectively provided on either side of the shaft seat along the width of the shaft seat. Both the first and second swing arms are rotatably connected to the shaft seat. The door panel assembly includes a first door panel and a second door panel. The first door panel is connected to the first swing arm. The second door panel is connected to the second swing arm. The metal support plate is located between the door panel assembly and the flexible display. The metal support plate includes opposing connecting ends and free ends. The connecting end is connected to the first door panel. The free end is located on the side of the second door panel facing the flexible display and is free relative to the second door panel. The free end includes an upper surface facing the flexible display, a lower surface facing the second door panel, and a transition surface. The transition surface connects the upper and lower surfaces. The lower surface is curved. The thickness of the free end decreases as it moves away from the connecting end.

[0040] In this embodiment, the free end of the metal support sheet can come into direct contact with the second door panel. No isolation structure is provided between the free end and the second door panel. During the folding or unfolding of the second door panel, the free end slides relative to the second door panel, causing frictional resistance between the free end and the second door panel. Since the lower surface of the free end is a curved surface with a relatively smooth transition, the free end is less likely to locally squeeze the second door panel during relative movement between the free end and the second door panel, thereby making the relative movement between the free end and the second door panel smoother and gentler. Furthermore, during the relative movement between the free end and the second door panel, it is less likely to produce abnormal noise due to friction between the two. This is beneficial to improving the quietness of the electronic device during the switching process between the unfolded state and the folded state, enhancing the user experience, and also helping to reduce the possibility of scratches on the second door panel caused by the free end. In addition, the processing difficulty of the free end of this embodiment is relatively low, and there is no need to provide an isolation structure on the second door panel, which helps to reduce costs.

[0041] In a possible implementation manner, the transition connection surface is a curved surface, and the lower surface, the transition connection surface, and the upper surface are smoothly transitioned. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0067] The electronic device in the embodiments of the present application may be referred to as user equipment (UE) or terminal, etc. For example, the electronic device may be a tablet computer (portable Android device, PAD), a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and other mobile terminals or fixed terminals. In the embodiments of the present application, the form of the terminal device is not specifically limited.

[0068] In an embodiment of the present application, FIG1 schematically illustrates the structure of an electronic device 10. Referring to FIG1 , the electronic device 10 is described as a handheld device with wireless communication capabilities. For example, the handheld device with wireless communication capabilities may be a foldable electronic device 10. Electronic device 10 may be a foldable mobile phone including a foldable flexible display.

[0069] Figure 2 schematically illustrates the structure of the electronic device 10 in a semi-folded state. Figure 3 schematically illustrates the structure of the electronic device 10 in a folded state. Referring to Figures 1 to 3, the electronic device 10 includes a housing 20. The housing 20 includes at least two frames 30 and a hinge assembly 40, as an example. The two frames 30 are located on either side of the hinge assembly 40. The two frames 30 are rotatably connected to the hinge assembly 40. For example, the two frames 30 can be connected to the hinge assembly 40 by welding or fastening. The two frames 30 can be rotated and folded. When the two frames 30 are close to each other and stacked, the electronic device 10 is in a folded state. When the two frames 30 move away from the stacked state and rotate until they cannot rotate, the electronic device 10 is in an unfolded state. The process of the two frames 30 moving from the folded state to the unfolded state is called the unfolding process, while the process of the two frames 30 moving from the unfolded state to the folded state is called the folding process. For example, when the electronic device 10 is in the folded state, the two frames 30 are stacked to form a two-layer structure. For example, the frame 30 may include a middle frame or a back cover, and the frame 30 may be connected to the hinge device 40 via the middle frame.

[0070] FIG4 schematically shows a partial exploded structure of the electronic device 10. Referring to FIG1 and FIG4 , the electronic device 10 further includes a flexible display screen 50. The flexible display screen 50 is covered on the housing 20. The hinge device 40 is disposed on the backlight side of the flexible display screen 50. The housing 20 can provide a mounting base for the flexible display screen 50. The flexible display screen 50 includes a display portion for displaying image information. The side of the flexible display screen 50 for displaying image information is the light-emitting side. The backlight side and the light-emitting side are arranged opposite to each other. The flexible display screen 50 can have a touch function. The user can touch the display area of ​​the flexible display screen 50 with their hand to execute corresponding operation instructions.

[0071] The flexible display 50 is inherently bendable and can be folded when subjected to external force. When the electronic device 10 is in the unfolded state, the display portion of the flexible display 50 unfolds to present image information to the user. The display portion may include a first display area 51, a second display area 52, and a third display area 53. The first display area 51 and the second display area 52 are respectively provided to correspond to the two frames 30. The third display area 53 may be provided to correspond to the hinge assembly 40.

[0072] When the two frames 30 are folded, the display unit is in a bent state. The first display area 51 and the second display area 52 of the display unit can overlap each other, and the third display area 53 can be bent into an arc shape, for example, the third display area 53 can be bent into a teardrop shape.

[0073] When the two frames 30 are in the unfolded state, the display portion is in the unfolded state, and the first display area 51, the second display area 52, and the third display area 53 are flat. The electronic device 10 can change its overall size by folding or unfolding, and can also have a larger display area in the unfolded state.

[0074] The two frames 30 of the electronic device 10 may each be provided with a printed circuit board (PCB) and an electronic device. The electronic device is provided on the PCB. For example, the electronic device may include, but is not limited to, a processor, a memory, or a camera module. The PCB in one frame 30 may serve as a main board.

[0075] In the related art, Figure 5 schematically shows a partial cross-sectional view of an electronic device 10 in the unfolded state. Figure 6 schematically shows a partial cross-sectional view of a metal support sheet in the related art. Figure 7 schematically shows a partial cross-sectional view of an electronic device 10 in the folded state. As shown in Figures 5 and 7, due to the relatively low structural strength of the flexible display 50, there is a possibility of structural damage to the flexible display 50 when subjected to localized impact from external structural components. Therefore, a metal support sheet 44 is provided between the hinge assembly 40 and the flexible display 50. The metal support sheet 44 isolates the hinge assembly 40 from the flexible display 50, thereby acting as a buffer between the hinge assembly 40 and the flexible display 50, effectively improving the impact resistance of the flexible display 50 and reducing the possibility of structural damage to the flexible display 50 caused by localized impact from structural components in the hinge assembly 40. One end of the metal support sheet 44 is connected to the door panel of the hinge assembly 40, and the other end is a free end 442 that is in a free state. The free end 442 has a sharp edge S. During the folding and unfolding of the electronic device 10, the hinge assembly 40 can cause the metal support sheet 44 to bend or unfold. During this process, the free end 442 of the metal support sheet 44 slides relative to the corresponding door panel, making it easy for the sharp edge S of the free end 442 to scrape against structural components along the sliding path, producing unusual noise. To alleviate the problem of unusual noise during folding or unfolding, a protective patch M is provided on the door panel corresponding to the free end 442 in the hinge assembly 40. The protective patch M is fixed to the door panel so that the relative position of the protective patch M and the door panel does not change. Although the protective patch M can help reduce the possibility of the free end 442 of the metal support sheet 44 scraping against other structural components during sliding, the protective patch M needs to be provided above all structural components on the door panel that may scrape against the free end 442. Due to the complex structure of the door panel itself and the large number of structural components, the process of providing the protective patch M on the door panel is difficult and costly.

[0076] In the electronic device 10 provided in the embodiment of the present application, an isolation gasket is provided on the metal support sheet 44. The isolation gasket moves synchronously with the free end 442 of the metal support sheet 44. The isolation gasket can isolate the metal support sheet 44 from the corresponding door panel. During the folding and unfolding of the electronic device 10, the metal support sheet 44 is less likely to rub against other structural components and produce abnormal noise. Furthermore, the process of joining the isolation gasket and the metal support sheet 44 is simple, which helps reduce costs.

[0077] Figure 8 schematically illustrates a partial cross-sectional view of the electronic device 10 in its unfolded state. Figure 9 schematically illustrates a partial cross-sectional view of the electronic device 10 in its folded state. Referring to Figures 8 and 9 , the electronic device 10 according to an embodiment of the present application includes a hinge assembly 40. The hinge assembly 40 includes a shaft seat 41, a swing arm assembly 42, a door panel assembly 43, a metal support sheet 44, and an isolation gasket 45.

[0078] The shaft seat 41 can shield other structural parts on the hinge device 40, making the electronic device 10 neat and beautiful in appearance. When the two frames 30 rotate relative to the hinge device 40, the position of the shaft seat 41 can remain relatively fixed. The shaft seat 41 can provide an installation base for related structural parts in the hinge device 40. The shaft seat 41 can be a bar-shaped structure. In some examples, when the two frames 30 are in the unfolded state, the two frames 30 can shield the shaft seat 41 so that the shaft seat 41 is in an invisible state. When the two frames 30 are in the folded state, at least part of the shaft seat 41 can be exposed from the two frames 30 and be in a visible state.

[0079] The swing arm assembly 42 includes a first swing arm 421 and a second swing arm 422. The first swing arm 421 and the second swing arm 422 are respectively disposed on either side of the axle base 41 along the width direction Y of the axle base 41. The first swing arm 421 and the second swing arm 422 are both rotatably connected to the axle base 41. The first swing arm 421 and the second swing arm 422 can each be connected to a frame 30. During the folding or unfolding of the two frames 30, the two frames 30 can respectively drive the corresponding first swing arm 421 and the second swing arm 422 to rotate relative to the axle base 41, thereby switching the first swing arm 421 and the second swing arm 422 between a folded position and an unfolded position.

[0080] The door panel assembly 43 includes a first door panel 431 and a second door panel 432. The first door panel 431 and the second door panel 432 are respectively provided on either side of the shaft base 41 along the width direction Y of the shaft base 41. The first door panel 431 and the second door panel 432 are located below the flexible display screen 50. The first door panel 431 is connected to the first swing arm 421. The second door panel 432 is connected to the second swing arm 422. When the first swing arm 421 and the second swing arm 422 rotate relative to the shaft base 41, the first door panel 431 and the second door panel 432 respectively rotate with the first swing arm 421 and the second swing arm 422 relative to the shaft base 41, thereby enabling the first door panel 431 and the second door panel 432 to switch between a folded position and an unfolded position. When the flexible display screen 50 is folded, the first door panel 431 and the second door panel 432 can provide support for the flexible display screen 50, thereby guiding the flexible display screen 50 to bend toward the expected bending shape. For example, the first door panel 431 and the second door panel 432 are arranged corresponding to the third display area 53 of the flexible display screen 50, so that the third display area 53 of the flexible display screen 50 can be easily bent into a water drop shape.

[0081] The metal support sheet 44 is disposed between the door panel assembly 43 and the flexible display screen 50. The metal support sheet 44 is not connected to the flexible display screen 50. The metal support sheet 44 includes a connecting end 441 and a free end 442. The connecting end 441 and the free end 442 are arranged opposite each other along the width direction Y of the shaft seat 41. The connecting end 441 of the metal support sheet 44 is connected to the first door panel 431. The free end 442 of the metal support sheet 44 is located on the side of the second door panel 432 facing the flexible display screen 50 and is free relative to the second door panel 432. During the folding process of the first and second door panels 431 and 432, the metal support sheet 44 folds under the action of the first and second door panels 431 and 432. The shape of the folded metal support sheet 44 can match the shape of the third display area 53. The metal support sheet 44 can provide support for the folded third display area 53. The metal support sheet 44 itself can be elastic. During the unfolding of the first door panel 431 and the second door panel 432, the metal support sheet 44 will unfold under the action of its own elastic restoring force. The metal support sheet 44 in the unfolded state can support the third display area 53, reducing the possibility of the third display area 53 collapsing and deforming. During the folding or unfolding of the metal support sheet 44, the relative position between the connecting end 441 of the metal support sheet 44 and the first door panel 431 does not change, while the free end 442 of the metal support sheet 44 is in a free state, allowing the free end 442 of the metal support sheet 44 to move relative to the second door panel 432, and the relative position between the free end 442 and the second door panel 432 can change. During the folding or unfolding of the metal support sheet 44, the metal support sheet 44 can move relative to the flexible display screen 50.

[0082] For example, the material of the metal support sheet 44 may be, but is not limited to, stainless steel or titanium alloy. The shape of the metal support sheet 44 in the expanded state may be, but is not limited to, a rectangle. The length direction of the metal support sheet 44 is the same as the length direction X of the shaft seat 41.

[0083] The isolation gasket 45 is connected to the metal support sheet 44. Along the length direction X of the shaft seat 41, the isolation gasket 45 covers at least part of the free end 442. The isolation gasket 45 isolates the second door panel 432 from the free end 442 of the metal support sheet 44, so that the second door panel 432 and the free end 442 of the metal support sheet 44 are in a state of no direct contact. The isolation gasket 45 and the surface of the second door panel 432 facing the flexible display screen 50 can be in a contact state. The isolation gasket 45 is fixed to the metal support sheet 44, so that the relative position between the isolation gasket 45 and the metal support sheet 44 does not change. In the process of switching the metal support sheet 44 between the folded state and the unfolded state, the isolation gasket 45 and the free end 442 of the metal support sheet 44 move synchronously, so that the isolation gasket 45 and the free end 442 of the metal support sheet 44 can both move relative to the second door panel 432.

[0084] Exemplarily, the surface of the isolation gasket 45 facing the second door panel 432 can be a smooth surface, that is, a surface with a relatively small surface roughness, for example, the surface roughness ranges from 0.5 microns (μm) to 1.6 microns, so that in the process of the isolation gasket 45 sliding relative to the second door panel 432, it is beneficial to reduce the friction resistance between the isolation gasket 45 and the second door panel 432, which is beneficial to improve the smoothness of the folding or unfolding process of the electronic device 10 and enhance the user experience.

[0085] In the electronic device 10 of the embodiment of the present application, the metal support sheet 44 can isolate the flexible display 50 from the structural components of the hinge assembly 40, for example, isolating the flexible display 50 from the shaft seat 41, the swing arm assembly 42, and the door panel assembly 43 of the hinge assembly 40. This reduces the possibility of structural damage to the flexible display 50 caused by impact with the structural components of the hinge assembly 40 during folding or unfolding. The metal support sheet 44 can fold or unfold along with the door panel assembly 43. The metal support sheet 44 is provided with an isolation gasket 45. During the folding or unfolding process, the isolation gasket 45 moves along with the metal support sheet 44. The isolation gasket 45 can cover at least a portion of the free end 442, thereby isolating the free end 442 from the second door panel 432. This reduces the likelihood of contact between the free end 442 and the second door panel 432. Consequently, when the metal support sheet 44 is folded or unfolded, the free end 442 is less likely to rub against the structural components of the second door panel 432, thereby reducing the possibility of abnormal noise caused by direct rubbing between the free end 442 and the structural components of the second door panel 432. Furthermore, the provision of the isolation gasket 45 on the metal support sheet 44 makes the process of joining the isolation gasket 45 and the metal support sheet 44 relatively simple, thereby reducing costs.

[0086] In some implementations, Figure 10 schematically illustrates a partial structure of the metal support sheet 44 and isolation gasket 45 in a bent state. As shown in Figure 10 , the isolation gasket 45 extends continuously along the length direction X of the shaft seat 41. The length of the isolation gasket 45 can be shorter than the length of the free end 442, such that the isolation gasket 45 partially covers the free end 442 along the length direction X of the shaft seat 41. The shape of the isolation gasket 45 in the expanded state can be, but is not limited to, a rectangle. The length direction of the isolation gasket 45 is the same as the length direction X of the shaft seat 41.

[0087] In some feasible embodiments, Figure 11 schematically shows the local structure of the metal support sheet 44 and the isolation gasket 45 in a bent state. Figure 12 is an enlarged view of point W in Figure 11. As shown in Figures 11 and 12, along the length direction X of the shaft seat 41, the isolation gasket 45 covers the entire free end 442. The isolation gasket 45 extends continuously, and the length of the isolation gasket 45 can be equal to the length of the free end 442. Therefore, in the length direction X of the shaft seat 41, an isolation gasket 45 is provided between any position of the free end 442 and the second door panel 432. The isolation gasket 45 can fully cover the free end 442, thereby further enhancing the isolation effect, which is beneficial to reducing the possibility of contact and scratching between any position of the free end 442 and the second door panel 432.

[0088] In some examples, Figure 13 schematically shows the local structure of the metal support sheet 44 and the isolation gasket 45 in a bent state. As shown in Figure 13, the rotating shaft device 40 also includes a shielding sheet 46. Along the length direction X of the shaft seat 41, the two ends of the isolation gasket 45 are connected to the shielding sheet 46. The shielding sheet 46 shields the free end 442 of the metal support sheet 44. Exemplarily, in the length direction X of the shaft seat 41, the isolation gasket 45 fully covers the free end 442. The isolation gasket 45 does not cover the two end surfaces of the free end 442 in the length direction. The shielding sheet 46 can cover the end surface of the free end 442. The isolation gasket 45 and the shielding sheet 46 can jointly cover the free end 442 to further reduce the exposed area of ​​the free end 442, which is conducive to further reducing the possibility of the free end 442 being scratched against external structural parts.

[0089] Exemplarily, the material of the isolation pad 45 can be the same as that of the shielding sheet 46. The isolation pad 45 and the shielding sheet 46 are an integrally formed structure.

[0090] As shown in Figure 13, the isolation gasket 45 may include a first connecting section 451, a second connecting section 452, and a bent connecting section 453. The first connecting section 451 is disposed on the side of the metal support sheet 44 facing the flexible display 50. For example, the first connecting section 451 may be connected to the surface of the metal support sheet 44 facing the flexible display 50. The second connecting section 452 is disposed on the side of the metal support sheet 44 facing the second door panel 432. For example, the second connecting section 452 may be connected to the surface of the metal support sheet 44 facing the second door panel 432. The bent connecting section 453 connects the first connecting section 451 and the second connecting section 452. The first connecting section 451, the bent connecting section 453, and the second connecting section 452 together form a receiving space. The free end 442 of the metal support sheet 44 is inserted into the receiving space, so that the isolation gasket 45 covers the free end 442. The isolation gasket 45 itself has a relatively simple structure, which helps to reduce the difficulty and cost of manufacturing the isolation gasket 45.

[0091] In some examples, as shown in Figures 11 and 12 , the first connecting segment 451, the bent connecting segment 453, and the second connecting segment 452 all extend continuously along the length direction X of the shaft seat 41. That is, there is one first connecting segment 451, one bent connecting segment 453, and one second connecting segment 452. The length of the first connecting segment 451 is equal to the length of the bent connecting segment 453. The length of the bent connecting segment 453 is equal to the length of the second connecting segment 452. For example, the shape of the isolation gasket 45 in the expanded state can be rectangular. The length direction of the isolation gasket 45 is the same as the length direction X of the shaft seat 41.

[0092] Figure 14 schematically illustrates the partial structure of the metal support sheet 44 and the isolation gasket 45 when connected. As shown in Figure 14 , the free end 442 includes an upper surface 442a facing the flexible display 50, a lower surface 442b facing the second door panel 432, and a transition surface 442c. The transition surface 442c connects the upper surface 442a and the lower surface 442b. The upper surface 442a of the free end 442 is positioned away from the second door panel 432. The first connecting section 451 can cover the upper surface 442a of the free end 442. The second connecting section 452 can cover the lower surface 442b of the free end 442. The bent connecting section 453 can cover the transition surface 442c. Exemplarily, the transition surface 442c of the free end 442 can be flat. Exemplarily, the transition surface 442c of the free end 442 can be curved. The bent connecting section 453 is arc-shaped. For example, the transition connection surface 442c may be an arc surface, and the bent connection section 453 may be an arc shape.

[0093] In the thickness direction of the metal support sheet 44, the thickness of the first connecting section 451 and the second connecting section 452 can be set to a relatively small size, which is conducive to reducing the space occupancy rate of the isolation gasket 45 in the thickness direction of the metal support sheet 44, and reducing the possibility of affecting the lightweight design of the electronic device 10 due to the large thickness of the isolation gasket 45.

[0094] In some examples, FIG15 schematically shows a partial structure in which the metal support sheet 44 and the isolation gasket 45 are in a bent state. As shown in FIG15 , the number of the second connecting segments 452 is more than two. Along the length direction X of the shaft seat 41, more than two second connecting segments 452 are arranged at intervals. An escape space is formed between two adjacent second connecting segments 452. The portion of the free end 442 corresponding to the escape space is in an exposed state. The second connecting segment 452 is located between the free end 442 and the second door panel 432. The second connecting segment 452 can be set accordingly according to the position of the structural member on the second door panel 432 that needs to be isolated from the free end 442, and the second connecting segment 452 can be omitted in the area on the second door panel 432 that does not need to be isolated from the free end 442. Therefore, the arrangement of the second connecting segment 452 in this embodiment is conducive to saving the use of the isolation gasket 45 and reducing production costs. Exemplarily, along the length direction X of the shaft seat 41 , the first connecting segment 451 and the bent connecting segment 453 may both extend continuously, that is, the number of the first connecting segment 451 and the number of the bent connecting segment 453 are both one.

[0095] For example, Figure 16 schematically shows the local structure of the metal support sheet 44 and the isolation gasket 45 in a bent state. As shown in Figure 16, the number of the bent connecting sections 453 is more than two. Along the length direction X of the shaft seat 41, more than two bent connecting sections 453 are arranged at intervals. The bent connecting sections 453 are arranged in a one-to-one correspondence with the second connecting sections 452. The number of the bent connecting sections 453 is the same as the number of the second connecting sections 452. The manner in which the bent connecting sections 453 are arranged in correspondence with the second connecting sections 452 is conducive to further saving the use of the isolation gasket 45 and reducing production costs. For example, in the length direction X of the shaft seat 41, the length of the bent connecting section 453 is equal to the length of the second connecting section 452. For example, along the length direction X of the shaft seat 41, the first connecting section 451 can extend continuously, that is, the number of the first connecting section 451 is one.

[0096] For example, FIG17 schematically shows the local structure of the metal support sheet 44 and the isolation gasket 45 in a bent state. FIG18 schematically shows the local structure of the metal support sheet 44 and the isolation gasket 45 in an expanded state. As shown in FIG17 and FIG18 , the number of the first connecting segments 451 is more than two. Along the length direction X of the shaft seat 41, more than two first connecting segments 451 are arranged at intervals. The first connecting segments 451 and the bent connecting segments 453 are arranged in a one-to-one correspondence. The number of the first connecting segments 451 is the same as the number of the bent connecting segments 453. The number of the bent connecting segments 453 is the same as the number of the second connecting segments 452. Along the width direction Y of the shaft seat 41, one first connecting segment 451, one bent connecting segment 453 and one second connecting segment 452 are interconnected. The arrangement of the first connecting segment 451 is conducive to further saving the use of the isolation gasket 45 and reducing production costs.

[0097] In some examples, Figure 19 schematically illustrates a partial cross-sectional view of the electronic device 10 in a folded state. As shown in Figure 19 , a first connecting segment 451 is disposed on the side of the metal support sheet 44 facing the flexible display 50. The first connecting segment 451 can separate the metal support sheet 44 from the flexible display 50, providing protection for the flexible display 50 and reducing the likelihood of the metal support sheet 44 directly scratching the flexible display 50.

[0098] For example, along the width direction Y of the shaft seat 41, the width of the first connecting segment 451 is greater than the width of the second connecting segment 452. In the expanded state of the metal support sheet 44, the orthographic projection area of ​​the first connecting segment 451 on the metal support sheet 44 can be greater than the orthographic projection area of ​​the second connecting segment 452 on the metal support sheet 44. For example, the first connecting segment 451 can cover the surface of the metal support sheet 44 except for the connecting segment, or the first connecting segment 451 can cover the entire surface of the metal support sheet 44 facing the flexible display 50, which helps maintain a relatively large area for the first connecting segment 451 and improves the protective performance.

[0099] In some examples, the second connecting section 452 is disposed on the side of the metal support sheet 44 facing the second door panel 432. A portion of the second connecting section 452 may be located between the second door panel 432 and the metal support sheet 44, while another portion may be located between the metal support sheet 44 and the swing arm assembly 42, and between the metal support sheet 44 and the axle seat 41. Thus, the second connecting section 452 can isolate the metal support sheet 44 from the swing arm assembly 42, thereby reducing the possibility of contact between the metal support sheet 44 and the swing arm assembly 42, which could cause scratches or abnormal noise between the two. Furthermore, the second connecting section 452 can isolate the metal support sheet 44 from the axle seat 41, thereby reducing the possibility of contact between the metal support sheet 44 and the axle seat 41, which could cause scratches or abnormal noise between the two. The second connecting section 452 can cover the surface of the metal support sheet 44 except the connecting section, or the second connecting section 452 can cover the entire surface of the metal support sheet 44 facing away from the flexible display screen 50, which is beneficial for maintaining a relatively large area of ​​the second connecting section 452 and improving the protective performance.

[0100] In some examples, along the width direction Y of the shaft seat 41, the width of the first connecting segment 451 is smaller than the width of the second connecting segment 452. In the expanded metal support sheet 44, the orthographic projection area of ​​the first connecting segment 451 on the metal support sheet 44 can be smaller than the orthographic projection area of ​​the second connecting segment 452 on the metal support sheet 44.

[0101] In some examples, along the width direction Y of the shaft seat 41 , the width of the first connecting segment 451 is equal to the width of the second connecting segment 452 .

[0102] In some feasible embodiments, the isolation gasket 45 is a flexible gasket. The rigidity of the isolation gasket 45 is less than that of the second door panel 432. When the isolation gasket 45 and the second door panel 432 slide relative to each other, the isolation gasket 45 can act as an effective buffer, reducing the possibility of abnormal noise between the isolation gasket 45 and the second door panel 432, and also reducing the possibility of scratches on the second door panel 432 caused by contact and scraping between the isolation gasket 45 and the second door panel 432. In addition, the isolation gasket 45 can be processed and manufactured separately. The isolation gasket 45 is bendable. During the assembly process of the isolation gasket 45 and the metal support sheet 44, the isolation gasket 45 can be easily deformed to match the shape of the metal support sheet 44, reducing the possibility of a gap between the isolation gasket 45 and the metal support sheet 44 due to shape mismatch after the isolation gasket 45 and the metal support sheet 44 are assembled. The rigidity of the isolation gasket 45 is less than that of the metal support sheet 44. The first connecting section 451 located between the metal support sheet 44 and the flexible display screen 50 can play a buffering role, so that the flexible display screen 50 and the first connecting section 451 can be in flexible contact, which is beneficial to further reduce the possibility of structural damage to the flexible display screen 50.

[0103] In some achievable embodiments, the isolation gasket 45 is an insulating gasket. The isolation gasket 45 has insulating isolation properties. The portion of the isolation gasket 45 located between the flexible display screen 50 and the metal support sheet 44 (e.g., the first connecting section 451) can play an insulating isolation role, reducing the possibility of electrical signals being transmitted between the flexible display screen 50 and the metal support sheet 44 through the metal support sheet 44. The isolation gasket 45 having insulating properties can also have good flexibility. It is not easy for the flexible display screen 50 and the isolation gasket 45 to generate noise due to collision or friction between the two, which is beneficial to improving the quietness of the electronic device 10 during the switching process between the unfolded state and the folded state, and is also beneficial to reducing the possibility of scratches on the flexible display screen 50 caused by the isolation gasket 45.

[0104] In some examples, the isolation spacer 45 may be a plastic film. For example, the material of the isolation spacer 45 may include, but is not limited to, polyethylene terephthalate, polyvinyl chloride, polyethylene, polypropylene, or polystyrene. For example, the isolation spacer 45 may be a mylar sheet.

[0105] In some examples, an insulating material may be sprayed onto the metal support sheet 44 using a surface spraying process to form an isolation spacer 45 having insulating properties.

[0106] In some possible implementations, Figure 20 schematically illustrates the partial structure of the metal support sheet 44 and isolation gasket 45 in an assembled state. As shown in Figure 20 , the free end 442 includes an upper surface 442a facing the flexible display 50, a lower surface 442b facing the second door panel 432, and a transition surface 442c. The transition surface 442c connects the upper surface 442a and the lower surface 442b. The lower surface 442b of the free end 442 is curved. The thickness of the free end 442 decreases as it moves away from the connection end 441. The isolation gasket 45 covers at least a portion of the lower surface 442b. During movement of the free end 442 relative to the second door panel 432, the free end 442 is less likely to locally squeeze the isolation gasket 45, reducing the possibility of stress concentration on the isolation gasket 45, which could lead to cracks or damage. For example, the lower surface 442b of the free end 442 is curved. Illustratively, the thickness of the isolation spacer 45 is uniform.

[0107] In some examples, the transition surface 442c of the free end 442 is a curved surface. The lower surface 442b, transition surface 442c, and upper surface 442a form a smooth transition, eliminating sharp edges on the free end 442. This reduces the likelihood that the sharp edge of the free end 442 will locally press against the isolation gasket 45 and damage the isolation gasket 45. This further reduces the likelihood that damage to the isolation gasket 45 could lead to isolation failure and allow the free end 442 to directly scrape against the second door panel 432. Exemplarily, the transition surface 442c of the free end 442 is an arc-shaped surface. For example, the transition surface 442c is a circular arc.

[0108] In some examples, when the metal support sheet 44 is in the expanded state, the upper surface 442 a of the free end 442 may be a plane.

[0109] In some achievable embodiments, the connection end 441 of the metal support sheet 44 is bonded to the first door panel 431. An adhesive is applied to the connection end 441 or the first door panel 431, and then the connection end 441 and the first door panel 431 are bonded. The adhesive may be, for example, adhesive glue. The connection end 441 and the first door panel 431 are bonded so that no additional connecting components such as screws, clips or rivets are required between the connection end 441 and the first door panel 431. This, on the one hand, helps to reduce the complexity of the connection structure between the connection end 441 and the first door panel 431 and reduces the difficulty of assembly. On the other hand, there is no need to provide corresponding connection structures, such as holes, on the connection end 441 and the first door panel 431, which helps to reduce the difficulty of processing the connection end 441 and the first door panel 431 and improve the structural integrity of the connection end 441 and the first door panel 431.

[0110] In some implementations, the isolation gasket 45 is bonded to the metal support sheet 44. The isolation gasket 45 can be pre-fabricated separately and then secured to a predetermined position on the metal support sheet 44 through assembly. During assembly, an adhesive can be applied to either the isolation gasket 45 or the metal support sheet 44, and then the isolation gasket 45 and the metal support sheet 44 are bonded together. The adhesive can be, for example, adhesive glue. The bonding between the isolation gasket 45 and the metal support sheet 44 eliminates the need for additional connecting components such as screws, clips, or rivets. This reduces the complexity of the connection structure between the isolation gasket 45 and the metal support sheet 44, thus simplifying assembly. Furthermore, it eliminates the need for corresponding connecting structures, such as holes, on the isolation gasket 45 and the metal support sheet 44, thus reducing the difficulty of fabricating the isolation gasket 45 and the metal support sheet 44 and improving the structural integrity of the isolation gasket 45 and the metal support sheet 44.

[0111] Figure 21 schematically shows a partial cross-sectional structure of the electronic device 10 in an unfolded state. Figure 22 schematically shows a partial cross-sectional structure of the electronic device 10 in a folded state. Figure 23 schematically shows a partial structure of the metal support sheet 44. Figure 24 is an enlarged view of point P in Figure 23. Referring to Figures 21 to 24, an embodiment of the present application further provides an electronic device 10. The electronic device 10 of this embodiment has the same structure as the above-mentioned electronic device 10 and will not be described in detail here. The electronic device 10 includes a flexible display 50 and a hinge device 40. The metal support sheet 44 is arranged between the door panel assembly 43 and the flexible display 50. The metal support sheet 44 includes opposite connecting ends 441 and a free end 442. The connecting end 441 is connected to the first door panel 431. The free end 442 is located on the side of the second door panel 432 facing the flexible display 50, and is in a free state relative to the second door panel 432. Free end 442 includes an upper surface 442a facing the flexible display 50, a lower surface 442b facing the second door panel 432, and a transition surface 442c. Transition surface 442c connects upper surface 442a and lower surface 442b. Lower surface 442b of free end 442 is curved. The thickness of free end 442 decreases as it moves away from connecting end 441.

[0112] In this embodiment, the free end 442 of the metal support sheet 44 can come into direct contact with the second door panel 432. No isolation structure is provided between the free end 442 and the second door panel 432. During the folding or unfolding of the second door panel 432, the free end 442 slides relative to the second door panel 432, generating frictional resistance between the free end 442 and the second door panel 432. Because the lower surface 442b of the free end 442 is a curved surface with a relatively smooth transition, the free end 442 is less likely to locally squeeze the second door panel 432 during relative movement between the free end 442 and the second door panel 432. This makes the relative movement between the free end 442 and the second door panel 432 relatively smooth and gentle. Furthermore, during the relative movement between the free end 442 and the second door panel 432, it is less likely to cause abnormal noise due to scratching between the free end 442 and the second door panel 432. This helps to improve the quietness of the electronic device 10 during the switching process between the unfolded state and the folded state, enhances the user experience, and also helps to reduce the possibility of scratches on the second door panel 432 caused by the free end 442. In addition, the free end 442 of this embodiment is relatively easy to manufacture, and no isolation structure is required on the second door panel 432, which helps to reduce costs.

[0113] In some embodiments, the transition surface 442c of the free end 442 is a curved surface. The lower surface 442b, transition surface 442c, and upper surface 442a form a smooth transition, eliminating sharp edges on the free end 442. This reduces the possibility of scratches and creaks caused by the free end 442 and the second door panel 432 during relative motion. Furthermore, it reduces the possibility of the second door panel 432 being scratched by the free end 442. Furthermore, it reduces the possibility of the free end 442 scratching or damaging the flexible display screen 50 during the folding and unfolding of the metal support sheet 44. For example, the lower surface 442b of the free end 442 can be curved. The transition surface 442c of the free end 442 can be curved. For example, the transition surface 442c can be a circular arc. For example, the upper surface 442a of the free end 442 of the metal support sheet 44 in the unfolded state can be flat.
