Description

[0001] This application is a divisional application. The original application has the application number 202310765266.4 and the original application date is June 26, 2023. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, and in particular to an electronic device. Background Technology

[0003] With the explosive growth of electronic devices such as smartphones and tablets, their functions are becoming increasingly diverse. The different screen sizes of electronic devices result in varying user experiences for their functions. While screen sizes are increasing, larger screens lead to larger overall device sizes, making them inconvenient to carry. Advances in display technology have enabled the manufacture of flexible display modules, which include flexible displays. Compared to traditional screens, flexible displays offer significant advantages, such as bendability and flexibility. Flexible displays can be applied to foldable electronic devices. Foldable electronic devices consist of a housing and a hinge mechanism. The two housings can rotate relative to each other around the hinge mechanism to unfold or fold. A flexible display is then placed over the two housings. When the two housings are unfolded to the same plane, the flexible display is in an unfolded state with a large display area. When the two housings are folded together, the flexible display is in a folded state, and the electronic device has a smaller volume. However, during the unfolding or folding process of foldable electronic devices, internal components may collide or rub against each other, causing abnormal noises and affecting the user experience. Summary of the Invention

[0004] This application provides an electronic device that can reduce the possibility of abnormal noises during the folding or unfolding of the electronic device.

[0005] The first aspect of this application provides an electronic device including a flexible display screen and a rotating shaft.

[0006] A pivot assembly is disposed on the backlight side of the flexible display screen. The pivot assembly includes a bearing, a swing arm assembly, a door panel assembly, a metal support plate, and an isolation gasket. The swing arm assembly includes a first swing arm and a second swing arm. Along the width direction of the bearing, the first and second swing arms are respectively disposed on both sides of the bearing. Both the first and second swing arms are rotatably connected to the bearing. 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 disposed between the door panel assembly and the flexible display screen. The metal support plate includes a connecting end and a free end. 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 screen and is in a free state relative to the second door panel. The isolation gasket is connected to the metal support plate. Along the length direction of the bearing, the isolation gasket covers at least a portion of the free end. The isolation gasket isolates the second door panel from the free end.

[0007] In the electronic device of this application embodiment, the metal support sheet can isolate the flexible display screen from the structural components in the hinge device, such as isolating the flexible display screen from the hinge seat, swing arm assembly, and door panel assembly of the hinge device, thereby reducing the possibility of structural damage to the flexible display screen due to impact from the structural components of the hinge device 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, the isolation gasket moves along with the metal support sheet. The isolation gasket can cover at least part of the free end, thereby isolating the free end from the second door panel, making it difficult for the free end to come into contact with the second door panel. Consequently, during the folding or unfolding process, the free end of the metal support sheet 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 an isolation gasket on the metal support sheet makes the process of achieving mutual bonding between the isolation gasket and the metal support sheet relatively simple, which is beneficial to reducing costs.

[0008] In one possible implementation, the isolation shim covers the entire free end along the length of the shaft seat.

[0009] The isolation pad can provide complete coverage of the free end, thereby further improving the isolation effect and reducing the possibility of contact and scratches between any position on the free end and the second door panel.

[0010] In one possible implementation, the rotating shaft device further includes baffles. Along the length of the shaft seat, the baffles are connected to both ends of the insulating pad. The baffles block the free end.

[0011] The isolation pad and the shield can together cover the free end to further reduce the exposed area of ​​the free end, which helps to further reduce the possibility of the free end rubbing against external structural components.

[0012] In one possible implementation, the insulating pad includes a first connecting segment, a bent connecting segment, and a second connecting segment. The first connecting segment is disposed on the side of the metal support sheet facing the flexible display screen. The second connecting segment is disposed on the side of the metal support sheet facing the second door panel. The bent connecting segment connects the first connecting segment and the second connecting segment. The first connecting segment, the bent connecting segment, and the second connecting segment enclose a receiving space. The free end is inserted into the receiving space.

[0013] The isolation gasket itself has a relatively simple structure, which helps to reduce the difficulty of processing the isolation gasket and reduce the processing cost.

[0014] In one possible implementation, there are two or more second connecting segments. These two or more second connecting segments are spaced apart along the length of the shaft seat.

[0015] The way the second connecting section is configured in this embodiment helps to save the amount of isolation gaskets used and reduce production costs.

[0016] In one possible implementation, there are two or more bent connecting segments. Each bent connecting segment corresponds to a second connecting segment.

[0017] The way the bent connecting section is set in correspondence with the second connecting section helps to further save the amount of isolation gaskets used and reduce production costs.

[0018] In one possible implementation, there are two or more first connecting segments. Each first connecting segment corresponds to a bent connecting segment.

[0019] The way the first connecting section is set up helps to further reduce the amount of isolation gaskets used and reduce production costs.

[0020] In one possible implementation, the width of the first connecting segment is greater than the width of the second connecting segment along the width direction of the bearing.

[0021] In one possible implementation, the width of the first connecting segment is smaller than the width of the second connecting segment along the width direction of the bearing.

[0022] In one possible implementation, the width of the first connecting segment is greater than the width of the second connecting segment along the width direction of the bearing. The first connecting segment covers the entire surface of the metal support sheet facing the flexible display screen.

[0023] The first connecting section can isolate the metal support sheet and the flexible display screen, so that the first connecting section can play a protective role for the flexible display screen, which helps to reduce the possibility of the metal support sheet directly scratching the flexible display screen.

[0024] In one 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, as well as between the metal support plate and the bearing seat.

[0025] The second connecting section isolates 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 lead to scraping or abnormal noise. Simultaneously, the second connecting section isolates the metal support plate from the bearing seat, further reducing the possibility of contact between the metal support plate and the bearing seat, which could lead to scraping or abnormal noise.

[0026] In one possible implementation, the insulating pad is a flexible pad.

[0027] When the isolation pad slides relative to the second door panel, it effectively cushions the movement, reducing the likelihood of rattling noises between them and the second door panel, as well as the possibility of scratches on the second door panel caused by contact friction. The first connecting section located between the metal support sheet and the flexible display screen also acts as a buffer, allowing for flexible contact between the flexible display screen and the first connecting section, which further reduces the possibility of structural damage to the flexible display screen.

[0028] In one possible implementation, the insulating pad is a spacer.

[0029] The insulating pad located between the flexible display screen and the metal support sheet (e.g., the first connecting section) can serve as an insulating barrier, reducing the possibility of electrical signals being transmitted between the flexible display screen and the metal support sheet through the metal support sheet.

[0030] In one possible implementation, the free end includes an upper surface facing the flexible display screen, a lower surface facing the second door panel, and a transition connecting surface. The transition connecting surface connects the upper and lower surfaces. The lower surface is curved. The thickness of the free end decreases in the direction away from the connecting end.

[0031] During the movement of the free end relative to the second door panel, the free end is less likely to cause local compression of the isolation gasket, reducing the possibility of stress concentration on the isolation gasket leading to cracks or damage.

[0032] In one possible implementation, the transition connection surface is curved. The lower surface, the transition connection surface, and the upper surface transition smoothly, thereby eliminating sharp edges on the free end. This reduces the possibility that sharp edges on the free end could cause localized compression of the isolation gasket and damage to it, and further reduces the possibility that damage to the isolation gasket could lead to isolation failure and allow the free end to directly scrape against the second door panel.

[0033] In one possible implementation, the connecting end is bonded to the first door panel.

[0034] The connection end and the first door panel are bonded together, eliminating the need for additional screws, clips, or rivets. This reduces the complexity of the connection structure and assembly difficulty. Furthermore, it eliminates the need for additional connection structures, such as holes, on the connection end and the first door panel, thus reducing processing difficulty and improving structural integrity.

[0035] In one possible implementation, the isolation pad is bonded to the metal support sheet.

[0036] The isolation gasket and the metal support plate are bonded together, eliminating the need for additional screws, clips, or rivets. This reduces the complexity of the connection structure and assembly difficulty. Furthermore, it eliminates the need for additional connecting structures, such as holes, on the isolation gasket and metal support plate, thus reducing manufacturing complexity and improving structural integrity.

[0037] A second aspect of this application provides an electronic device including a flexible display screen and a rotating shaft.

[0038] A pivot assembly is located on the backlight side of the flexible display screen. The pivot assembly includes a bearing, 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. Along the width direction of the bearing, the first and second swing arms are respectively located on both sides of the bearing. Both the first and second swing arms are rotatably connected to the bearing. 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 screen. The metal support plate includes a connecting end and a free end. 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 screen and is in a free state relative to the second door panel. The free end includes an upper surface facing the flexible display screen, a lower surface facing the second door panel, and a transition connecting surface. The transition connecting surface connects the upper and lower surfaces. The lower surface is curved. The thickness of the free end decreases along the direction away from the connecting end.

[0039] In this embodiment, the free end of the metal support piece can directly contact 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, generating frictional resistance between them. Because the lower surface of the free end is a relatively smooth curved surface, the free end is less likely to exert localized pressure on the second door panel during relative movement. This results in a smoother and gentler relative movement between the free end and the second door panel, reducing the likelihood of abnormal noise caused by friction during their relative movement. This improves the quietness of the electronic device during the switching between unfolded and folded states, enhancing the user experience. It also reduces the possibility of scratches on the second door panel caused by the free end. Furthermore, the free end in this embodiment is easier to manufacture and does not require an isolation structure on the second door panel, thus reducing costs.

[0040] In one possible implementation, the transition connection surface is a curved surface, with the lower surface, the transition connection surface, and the upper surface smoothly transitioning. Attached Figure Description

[0079] The electronic devices in this application embodiment can be referred to as user equipment (UE) or terminals, etc. For example, electronic devices can be portable Android devices (PADs), personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, in-vehicle devices, wearable devices, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and other mobile or fixed terminals. This application embodiment does not specifically limit the form of the terminal device.

[0080] In the embodiments of this application, Figure 1 The structure of electronic device 10 is shown schematically. See also Figure 1 As shown, the example described is a handheld device with wireless communication capabilities, specifically electronic device 10. The handheld device with wireless communication capabilities could be, for example, a foldable electronic device 10. Electronic device 10 could be a foldable phone including a foldable flexible display screen.

[0081] Figure 2 The structure of the electronic device 10 in a semi-folded state is schematically shown. Figure 3 This schematically illustrates the structure of an electronic device in its folded state. See also... Figures 1 to 3As shown, the electronic device 10 includes a housing 20. The housing 20 is described as including at least two frames 30 and a hinge device 40. The two frames 30 are located on opposite sides of the hinge device 40. The two frames 30 are rotatably connected to the hinge device 40. For example, the two frames 30 can be connected to the hinge device 40 by welding or fasteners. The two frames 30 can rotate and fold. 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 each other from the stacked state and rotate until they cannot rotate further, 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 the unfolding process, and the process of moving from the unfolded state to the folded state is the folding process. Exemplarily, when the electronic device 10 is in the folded state, the two frames 30 are stacked, presenting a two-layer structure. Exemplarily, the frame 30 may include a middle frame or a back cover. The frame 30 can be connected to the hinge device 40 through the middle frame.

[0082] Figure 4 A partial exploded view of the electronic device 10 is schematically shown. See also Figure 1 and Figure 4 As shown, the electronic device 10 also includes a flexible display screen 50. The flexible display screen 50 covers the housing 20. A 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 section for displaying image information. The side of the flexible display screen 50 used for displaying image information is the light-emitting side. The backlight side and the light-emitting side are disposed opposite to each other. The flexible display screen 50 may have touch functionality. Users can execute corresponding operation commands by touching the display area of ​​the flexible display screen 50 with their hands.

[0083] The flexible display screen 50 is bendable and can be folded under external force. When the electronic device 10 is in the unfolded state, the display section of the flexible display screen 50 unfolds to present image information to the user. The display section 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 disposed corresponding to two frames 30. The third display area 53 may be disposed corresponding to the hinge device 40.

[0084] When the two frames 30 are in a folded state, the display section is in a bent state. The first display area 51 and the second display area 52 of the display section can be stacked on top of each other, while 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.

[0085] When the two frames 30 are in the unfolded state, the display unit is also in the unfolded state, while the first display area 51, the second display area 52, and the third display area 53 are in a flat state. The electronic device 10 can change its overall size by folding or unfolding, and can also have a large display area when unfolded.

[0086] The electronic device 10 can have a printed circuit board (PCB) and electronic components housed in its two frames 30, respectively. The electronic components are mounted on the PCB. For example, the electronic components may include, but are not limited to, a processor, memory, or a camera module. The PCB in one frame 30 can serve as the motherboard.

[0087] In related technologies, Figure 5 A partial cross-sectional view of the electronic device 10 of the related technology in an unfolded state is schematically shown. Figure 6 A partial structure of the metal support sheet of the related technology is shown schematically. Figure 7 A schematic partial cross-sectional view of an electronic device 10 of the related art in a folded state is shown. See also Figures 5 to 7As shown, due to the relatively low structural strength of the flexible display screen 50, it is susceptible to structural damage when subjected to localized impacts from external structural components. Therefore, a metal support plate 44 is provided between the hinge device 40 and the flexible display screen 50. The metal support plate 44 isolates the hinge device 40 from the flexible display screen 50, thus acting as a buffer between them, effectively improving the impact resistance of the flexible display screen 50 and reducing the possibility of structural damage caused by localized impacts from structural components in the hinge device 40. One end of the metal support plate 44 is connected to the door panel in the hinge device 40, and the other end is a free end 442 in a free state. The free end 442 has a sharp edge S. During the folding and unfolding process of the electronic device 10, the hinge device 40 can drive the metal support plate 44 to bend or unfold. During bending or unfolding, the free end 442 of the metal support piece 44 slides relative to the corresponding door panel, causing the sharp edge S of the free end 442 to easily rub against structural components along the sliding path, resulting in abnormal noise. To improve the problem of abnormal noise during folding or unfolding, a protective patch M is provided on the door panel corresponding to the free end 442 in the pivot device 40. The protective patch M is fixed to the door panel, ensuring that its relative position to the door panel does not change. Although the protective patch M can help reduce the rubbing of the free end 442 of the metal support piece 44 against other structural components during sliding, the protective patch M needs to be placed above all structural components on the door panel that may rub against the free end 442. Due to the complex structure of the door panel and the large number of structural components, the process of installing the protective patch M on the door panel is difficult and costly.

[0088] The electronic device 10 provided in this application embodiment has an isolation pad on a metal support plate 44. The isolation pad moves synchronously with the free end 442 of the metal support plate 44. The isolation pad can separate the metal support plate 44 and the corresponding door panel. During the folding and unfolding process of the electronic device 10, the metal support plate 44 is less likely to rub against other structural components and produce abnormal noise. At the same time, the bonding process between the isolation pad and the metal support plate 44 is simple, which helps to reduce costs.

[0089] Figure 8 A partial cross-sectional view of the electronic device 10 in its unfolded state is schematically shown. Figure 9 A partial cross-sectional view schematically showing the electronic device 10 in a folded state. See also Figure 8 and Figure 9 As shown, the electronic device 10 of this application embodiment includes a pivot device 40. The pivot device 40 includes a bearing 41, a swing arm assembly 42, a door panel assembly 43, a metal support plate 44, and an isolation pad 45.

[0090] The bearing seat 41 can shield other structural components on the rotating shaft assembly 40, resulting in a neat and aesthetically pleasing appearance for the electronic device 10. The position of the bearing seat 41 remains relatively fixed as the two frames 30 rotate relative to the rotating shaft assembly 40. The bearing seat 41 can provide a mounting base for related structural components within the rotating shaft assembly 40. The bearing seat 41 can be a strip-shaped structure. In some examples, when the two frames 30 are in an unfolded state, they can shield the bearing seat 41, making it invisible. When the two frames 30 are in a folded state, at least a portion of the bearing seat 41 can be exposed and visible through the two frames 30.

[0091] The swing arm assembly 42 includes a first swing arm 421 and a second swing arm 422. Along the width direction Y of the bearing seat 41, the first swing arm 421 and the second swing arm 422 are respectively provided on both sides of the bearing seat 41. Both the first swing arm 421 and the second swing arm 422 are rotatably connected to the bearing seat 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 bearing seat 41, so that the first swing arm 421 and the second swing arm 422 switch between a folded position and an unfolded position.

[0092] 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 disposed on both sides of the bearing seat 41 along the width direction Y. 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 a first swing arm 421. The second door panel 432 is connected to a second swing arm 422. When the first swing arm 421 and the second swing arm 422 rotate relative to the bearing seat 41, the first door panel 431 and the second door panel 432 respectively follow the rotation of the first swing arm 421 and the second swing arm 422 relative to the bearing seat 41, thereby allowing 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 in the expected bending shape. For example, the first door panel 431 and the second door panel 432 are set to correspond 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 teardrop shape.

[0093] A metal support piece 44 is disposed between the door panel assembly 43 and the flexible display screen 50. The metal support piece 44 and the flexible display screen 50 are not connected. The metal support piece 44 includes a connecting end 441 and a free end 442. Along the width direction Y of the bearing 41, the connecting end 441 and the free end 442 are arranged opposite to each other. The connecting end 441 of the metal support piece 44 is connected to the first door panel 431. The free end 442 of the metal support piece 44 is located on the side of the second door panel 432 facing the flexible display screen 50, and is in a free state relative to the second door panel 432. During the folding process of the first door panel 431 and the second door panel 432, the metal support piece 44 will fold under the action of the first door panel 431 and the second door panel 432. The shape of the folded metal support piece 44 can match the shape of the third display area 53. The metal support piece 44 can provide support for the folded third display area 53. The metal support piece 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 unfolds under its own elastic restoring force. In its unfolded state, the metal support sheet 44 can support the third display area 53, reducing the possibility of collapse or deformation. 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 remains unchanged, while the free end 442 of the metal support sheet 44 is in a free state, allowing the free end 442 to move relative to the second door panel 432, thus changing the relative position between them. 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.

[0094] For example, the material of the metal support plate 44 may be, but is not limited to, stainless steel or titanium alloy. The shape of the metal support plate 44 in the unfolded state may be, but is not limited to, rectangular. The length direction of the metal support plate 44 is the same as the length direction X of the bearing 41.

[0095] The isolation pad 45 is connected to the metal support plate 44. Along the length X of the bearing 41, the isolation pad 45 covers at least a portion of the free end 442. The isolation pad 45 isolates the second door panel 432 from the free end 442 of the metal support plate 44, ensuring that the second door panel 432 and the free end 442 of the metal support plate 44 do not directly contact each other. The isolation pad 45 can be in contact with the surface of the second door panel 432 facing the flexible display screen 50. The isolation pad 45 is fixed to the metal support plate 44, so that the relative position between the isolation pad 45 and the metal support plate 44 does not change. During the switching between the folded and unfolded states of the metal support plate 44, the isolation pad 45 and the free end 442 of the metal support plate 44 move synchronously, allowing both the isolation pad 45 and the free end 442 of the metal support plate 44 to move relative to the second door panel 432.

[0096] For example, the surface of the isolation pad 45 facing the second door panel 432 can be a smooth surface, that is, a surface with low surface roughness, for example, the surface roughness ranges from 0.5 micrometers (μm) to 1.6 micrometers. This helps to reduce the frictional resistance between the isolation pad 45 and the second door panel 432 during the sliding process of the isolation pad 45 relative to the second door panel 432, which helps to improve the smoothness of the folding or unfolding process of the electronic device 10 and improve the user experience.

[0097] In the electronic device 10 of this application embodiment, the metal support sheet 44 can isolate the flexible display screen 50 from the structural components in the pivot device 40, such as isolating the flexible display screen 50 from the pivot seat 41, the swing arm assembly 42, and the door panel assembly 43 of the pivot device 40, thereby reducing the possibility of structural damage to the flexible display screen 50 due to impact from the structural components of the pivot device 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 pad 45. During the folding or unfolding process, the isolation pad 45 moves along with the metal support sheet 44. The isolation pad 45 can cover at least part of the free end 442, thereby isolating the free end 442 from the second door panel 432. This makes it less likely for the free end 442 to come into contact with the second door panel 432, and consequently, during the folding or unfolding of the metal support sheet 44, the free end 442 is less likely to rub against the structural components of the second door panel 432, reducing the possibility of abnormal noise caused by direct friction between the free end 442 and the structural components of the second door panel 432. In addition, the method of setting the isolation pad 45 on the metal support sheet 44 makes the process of connecting the isolation pad 45 and the metal support sheet 44 relatively simple, which helps to reduce costs.

[0098] In some feasible ways, Figure 10The diagram schematically shows a partial structure where the metal support plate 44 and the insulating gasket 45 are in a bent state. See also... Figure 10 As shown, the isolation pad 45 extends continuously along the length direction X of the bearing seat 41. The length of the isolation pad 45 can be less than the length of the free end 442, so that the isolation pad 45 can partially cover the free end 442 along the length direction X of the bearing seat 41. The shape of the isolation pad 45 in the unfolded state can be, but is not limited to, rectangular. The length direction of the isolation pad 45 is the same as the length direction X of the bearing seat 41.

[0099] In some feasible ways, Figure 11 The diagram schematically shows a partial structure in which the metal support plate 44 and the isolation pad 45 are in a bent state. Figure 12 for Figure 11 A magnified view of point W in the middle. See also... Figure 11 and Figure 12 As shown, along the length direction X of the bearing seat 41, the isolation gasket 45 covers the entire free end 442. The isolation gasket 45 extends continuously, and its length can be equal to the length of the free end 442. Therefore, an isolation gasket 45 is provided at any position of the free end 442 and between the second door panel 432 along the length direction X of the bearing seat 41. The isolation gasket 45 can fully cover the free end 442, thereby further improving the isolation effect and reducing the possibility of contact and scratching between any position of the free end 442 and the second door panel 432.

[0100] In some examples, Figure 13 The diagram schematically shows a partial structure where the metal support plate 44 and the insulating gasket 45 are in a bent state. See also... Figure 13 As shown, the rotating shaft device 40 also includes a shielding plate 46. Along the length direction X of the shaft seat 41, the shielding plate 46 is connected to both ends of the isolation pad 45. The shielding plate 46 shields the free end 442 of the metal support plate 44. Exemplarily, in the length direction X of the shaft seat 41, the isolation pad 45 completely covers the free end 442. The isolation pad 45 does not cover the two end faces of the free end 442 in the length direction. The shielding plate 46 can cover the end faces of the free end 442. The isolation pad 45 and the shielding plate 46 can together cover the free end 442 to further reduce the exposed area of ​​the free end 442, which helps to further reduce the possibility of the free end 442 rubbing against external structural components.

[0101] For example, the material of the isolation pad 45 can be the same as the material of the shielding plate 46. The isolation pad 45 and the shielding plate 46 are integrally formed.

[0102] See Figure 13As shown, the isolation gasket 45 may include a first connecting segment 451, a second connecting segment 452, and a bent connecting segment 453. The first connecting segment 451 is disposed on the side of the metal support sheet 44 facing the flexible display screen 50. For example, the first connecting segment 451 may be connected to the surface of the metal support sheet 44 facing the flexible display screen 50. The second connecting segment 452 is disposed on the side of the metal support sheet 44 facing the second door panel 432. For example, the second connecting segment 452 may be connected to the surface of the metal support sheet 44 facing the second door panel 432. The bent connecting segment 453 connects the first connecting segment 451 and the second connecting segment 452. The first connecting segment 451, the bent connecting segment 453, and the second connecting segment 452 enclose and form an accommodating space. The free end 442 of the metal support sheet 44 is inserted into the accommodating 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 processing difficulty and processing cost of the isolation gasket 45.

[0103] See in some examples Figure 11 and Figure 12 As shown, along the length direction X of the bearing seat 41, the first connecting segment 451, the bent connecting segment 453, and the second connecting segment 452 all extend continuously, meaning there is one of each of the following: the first connecting segment 451, the bent connecting segment 453, and the 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 pad 45 in the unfolded state can be rectangular. The length direction of the isolation pad 45 is the same as the length direction X of the bearing seat 41.

[0104] Figure 14 A partial structure schematically showing the connection state of the metal support plate 44 and the insulating gasket 45. See also Figure 14 As shown, the free end 442 includes an upper surface 442a facing the flexible display screen 50, a lower surface 442b facing the second door panel 432, and a transition connecting surface 442c. The transition connecting surface 442c connects the upper surface 442a and the lower surface 442b. The upper surface 442a of the free end 442 is disposed away from the second door panel 432. A first connecting segment 451 may cover the upper surface 442a of the free end 442. A second connecting segment 452 may cover the lower surface 442b of the free end 442. A bent connecting segment 453 may cover the transition connecting surface 442c. Exemplarily, the transition connecting surface 442c of the free end 442 may be a plane. Exemplarily, the transition connecting surface 442c of the free end 442 may be a curved surface. The bent connecting segment 453 is arc-shaped. For example, the transition connecting surface 442c may be an arc surface, and the bent connecting segment 453 may be an arc shape.

[0105] In the thickness direction of the metal support sheet 44, the thickness of the first connecting segment 451 and the second connecting segment 452 can be set to a relatively small size, which helps to reduce the space occupancy rate of the isolation pad 45 in the thickness direction of the metal support sheet 44 and reduce the possibility of affecting the thin and light design of the electronic device 10 due to the large thickness of the isolation pad 45.

[0106] In some examples, Figure 15 The diagram schematically shows a partial structure where the metal support plate 44 and the insulating gasket 45 are in a bent state. See also... Figure 15 As shown, there are two or more second connecting segments 452. Along the length direction X of the bearing seat 41, two or more second connecting segments 452 are spaced apart. A clearance space is formed between adjacent second connecting segments 452. The portion of the free end 442 corresponding to the clearance space is exposed. 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 according to the position of the structural component on the second door panel 432 that needs to be isolated from the free end 442, while areas on the second door panel 432 that do not need to be isolated from the free end 442 can be left unset. Therefore, the arrangement of the second connecting segment 452 in this embodiment helps to save the amount of isolation gasket 45 used and reduce production costs. For example, along the length direction X of the bearing seat 41, both the first connecting segment 451 and the bent connecting segment 453 can extend continuously, that is, the number of each of the first connecting segment 451 and the bent connecting segment 453 is one.

[0107] For example, Figure 16 The diagram schematically shows a partial structure where the metal support plate 44 and the insulating gasket 45 are in a bent state. See also... Figure 16 As shown, there are two or more bent connecting segments 453. Along the length direction X of the shaft seat 41, two or more bent connecting segments 453 are spaced apart. Each bent connecting segment 453 corresponds one-to-one with a second connecting segment 452. The number of bent connecting segments 453 is the same as the number of second connecting segments 452. This correspondence between bent connecting segments 453 and second connecting segments 452 helps to further reduce the amount of insulating gasket 45 used and lower production costs. For example, in the length direction X of the shaft seat 41, the length of the bent connecting segment 453 is equal to the length of the second connecting segment 452. For example, along the length direction X of the shaft seat 41, the first connecting segment 451 can extend continuously, meaning there is only one first connecting segment 451.

[0108] For example, Figure 17 The diagram schematically shows a partial structure in which the metal support plate 44 and the isolation pad 45 are in a bent state. Figure 18 This schematically shows a partial structure with the metal support plate 44 and the isolation pad 45 in their deployed state. See also Figure 17 and Figure 18 As shown, there are two or more first connecting segments 451. Along the length direction X of the shaft seat 41, two or more first connecting segments 451 are spaced apart. Each first connecting segment 451 corresponds to a bent connecting segment 453. The number of first connecting segments 451 is the same as the number of bent connecting segments 453. The number of bent connecting segments 453 is the same as the number of 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. This arrangement of the first connecting segments 451 helps to further reduce the amount of insulating gasket 45 used and lower production costs.

[0109] In some examples, Figure 19 A partial cross-sectional view schematically showing the electronic device 10 in a folded state. See also Figure 19 As shown, the first connecting segment 451 is disposed on the side of the metal support sheet 44 facing the flexible display screen 50. The first connecting segment 451 can isolate the metal support sheet 44 and the flexible display screen 50, so that the first connecting segment 451 can protect the flexible display screen 50, which helps to reduce the possibility of the metal support sheet 44 directly scratching the flexible display screen 50.

[0110] For example, along the width direction Y of the bearing 41, the width of the first connecting segment 451 is greater than the width of the second connecting segment 452. In the unfolded state, the projected area of ​​the first connecting segment 451 on the metal support sheet 44 can be greater than the projected 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 excluding the connecting segment, or the first connecting segment 451 can cover the entire surface of the metal support sheet 44 facing the flexible display screen 50, which helps the first connecting segment 451 maintain a relatively large area and improves protective performance.

[0111] In some examples, the second connecting segment 452 is disposed on the side of the metal support piece 44 facing the second door panel 432. A portion of the second connecting segment 452 may be located between the second door panel 432 and the metal support piece 44, and another portion may be located between the metal support piece 44 and the swing arm assembly 42, and between the metal support piece 44 and the bearing seat 41. Therefore, the second connecting segment 452 can isolate the metal support piece 44 and the swing arm assembly 42, thereby reducing the possibility of the metal support piece 44 contacting the swing arm assembly 42 and causing scraping or abnormal noise between them. Simultaneously, the second connecting segment 452 can isolate the metal support piece 44 and the bearing seat 41, thereby reducing the possibility of the metal support piece 44 contacting the bearing seat 41 and causing scraping or abnormal noise between them. The second connecting segment 452 can cover the surface of the metal support sheet 44 except for the connecting segment, or the second connecting segment 452 can cover the entire surface of the metal support sheet 44 facing away from the flexible display screen 50, which helps to keep the second connecting segment 452 relatively large and improve the protective performance.

[0112] In some examples, along the width direction Y of the bearing 41, the width of the first connecting segment 451 is smaller than the width of the second connecting segment 452. In the unfolded state of the metal support plate 44, the orthographic projection area of ​​the first connecting segment 451 on the metal support plate 44 can be smaller than the orthographic projection area of ​​the second connecting segment 452 on the metal support plate 44.

[0113] In some examples, along the width direction Y of the bearing 41, the width of the first connecting segment 451 is equal to the width of the second connecting segment 452.

[0114] In some feasible implementations, the isolation pad 45 is a flexible pad. The stiffness of the isolation pad 45 is less than that of the second door panel 432. When the isolation pad 45 slides relative to the second door panel 432, the isolation pad 45 can effectively buffer the movement, reducing the possibility of abnormal noise between the isolation pad 45 and the second door panel 432, and also reducing the possibility of scratches on the second door panel 432 due to contact and friction between the isolation pad 45 and the second door panel 432. Furthermore, the isolation pad 45 can be manufactured independently. The isolation pad 45 is bendable. During the assembly of the isolation pad 45 and the metal support plate 44, the isolation pad 45 can easily deform to match the shape of the metal support plate 44, reducing the possibility of gaps appearing between the isolation pad 45 and the metal support plate 44 after assembly due to shape mismatch. The stiffness of the isolation pad 45 is less than that of the metal support plate 44. The first connecting segment 451 located between the metal support sheet 44 and the flexible display screen 50 can act as a buffer, allowing the flexible display screen 50 to make flexible contact with the first connecting segment 451, which helps to further reduce the possibility of structural damage to the flexible display screen 50.

[0115] In some feasible implementations, the isolation pad 45 is an insulating pad. The isolation pad 45 has insulating properties. The portion of the isolation pad 45 located between the flexible display screen 50 and the metal support sheet 44 (e.g., the first connecting segment 451) can act as an insulating barrier, 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 insulating isolation pad 45 itself can also possess good flexibility. Noise generated between the flexible display screen 50 and the isolation pad 45 due to mutual impact or friction is less likely, which helps improve the quietness of the electronic device 10 during the switching process between the unfolded and folded states, and also helps reduce the possibility of scratches appearing on the flexible display screen 50 due to scratches from the isolation pad 45.

[0116] In some examples, the insulating pad 45 may be a plastic film. Exemplarily, the material of the insulating pad 45 may include, but is not limited to, polyethylene terephthalate, polyvinyl chloride, polyethylene, polypropylene, or polystyrene. Exemplarily, the insulating pad 45 may be a Mylar sheet.

[0117] In some examples, an insulating material can be sprayed onto the metal support sheet 44 using a surface spraying process to form an insulating gasket 45.

[0118] In some feasible ways, Figure 20 A partial view of the assembled metal support plate 44 and the insulating gasket 45 is schematically shown. See also Figure 20As shown, the free end 442 includes an upper surface 442a facing the flexible display screen 50, a lower surface 442b facing the second door panel 432, and a transition connection surface 442c. The transition connection 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 in the direction away from the connecting end 441. An isolation pad 45 covers at least a portion of the lower surface 442b. During the movement of the free end 442 relative to the second door panel 432, the free end 442 is less likely to cause local compression of the isolation pad 45, reducing the possibility of stress concentration in the isolation pad 45 leading to cracks or damage. Exemplarily, the lower surface 442b of the free end 442 is an arc-shaped surface. Exemplarily, the thickness of the isolation pad 45 is uniform.

[0119] In some examples, the transition connection surface 442c of the free end 442 is curved. The lower surface 442b, the transition connection surface 442c, and the upper surface 442a transition smoothly, so that there are no sharp edges on the free end 442. This reduces the possibility that the sharp edges of the free end 442 may cause local compression of the isolation gasket 45 and damage to the isolation gasket 45, thereby reducing the possibility that the isolation gasket 45 may fail due to damage and allow the free end 442 to directly scrape against the second door panel 432. Exemplarily, the transition connection surface 442c of the free end 442 is an arc-shaped surface. For example, the transition connection surface 442c is a circular arc surface.

[0120] In some examples, the upper surface 442a of the free end 442 of the metal support sheet 44 in the unfolded state can be a plane.

[0121] In some feasible methods, the connecting end 441 of the metal support piece 44 is bonded to the first door panel 431. An adhesive is applied to either the connecting end 441 or the first door panel 431, and then the connecting end 441 and the first door panel 431 are bonded together. The adhesive can be, for example, adhesive glue. Bonding the connecting end 441 to the first door panel 431 eliminates the need for additional connecting components such as screws, clips, or rivets. This reduces the complexity of the connection structure between the connecting end 441 and the first door panel 431, lowering assembly difficulty. Furthermore, it eliminates the need for corresponding connecting structures, such as holes, on the connecting end 441 and the first door panel 431, reducing processing difficulty and improving structural integrity.

[0122] In some feasible methods, the isolation gasket 45 is bonded to the metal support plate 44. The isolation gasket 45 can be pre-manufactured separately and then fixed to a predetermined position on the metal support plate 44 by assembly. During assembly, an adhesive can be applied to either the isolation gasket 45 or the metal support plate 44, and then the isolation gasket 45 and the metal support plate 44 are bonded together. The adhesive can be, for example, an adhesive glue. Bonding the isolation gasket 45 to the metal support plate 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 plate 44, lowering assembly difficulty. Furthermore, it eliminates the need for corresponding connecting structures, such as holes, on the isolation gasket 45 and the metal support plate 44, reducing manufacturing difficulty and improving structural integrity.

[0123] Figure 21 A partial cross-sectional view of the electronic device 10 in its unfolded state is schematically shown. Figure 22 A partial cross-sectional view of the electronic device 10 in a folded state is schematically shown. Figure 23 A partial structure of the metal support sheet 44 is schematically shown. Figure 24 for Figure 23 Enlarged view of point P in the middle. See also Figures 21 to 24 As shown, this application embodiment also provides an electronic device 10. The electronic device 10 of this embodiment has the same structure as the electronic device 10 described above, and will not be described in detail here. The electronic device 10 includes a flexible display screen 50 and a rotating shaft device 40. A metal support piece 44 is disposed between the door panel assembly 43 and the flexible display screen 50. The metal support piece 44 includes a connecting end 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 screen 50, and is in a free state relative to the second door panel 432. The free end 442 includes an upper surface 442a facing the flexible display screen 50, a lower surface 442b facing the second door panel 432, and a transition connecting surface 442c. The transition connecting 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 along the direction away from the connecting end 441.

[0124] In this embodiment, the free end 442 of the metal support piece 44 can directly contact 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, resulting in 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 relatively smooth curved surface, when the free end 442 and the second door panel 432 move relative to each other, the free end 442 is less likely to exert local pressure on the second door panel 432. This makes the relative movement between the free end 442 and the second door panel 432 smoother and gentler. Consequently, the free end 442 is less likely to rub against the second door panel 432 during the relative movement, thus reducing the noise generated. This helps improve the quietness of the electronic device 10 during the switching process between the unfolded and folded states, enhancing the user experience. It also helps reduce the possibility of scratches on the second door panel 432 caused by the free end 442. In addition, the free end 442 in this embodiment is easier to manufacture, and there is no need to set an isolation structure on the second door panel 432, which helps to reduce costs.

[0125] In some feasible implementations, the transition connection surface 442c of the free end 442 is curved. The lower surface 442b, the transition connection surface 442c, and the upper surface 442a transition smoothly, thus eliminating sharp edges on the free end 442. This helps to further reduce the possibility of scratches caused by friction between the free end 442 and the second door panel 432 during relative movement; it also helps to further reduce the possibility of scratches on the second door panel 432 caused by the free end 442; and further still, it helps to reduce 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 an arc-shaped surface. The transition connection surface 442c of the free end 442 is also an arc-shaped surface. For example, the transition connection surface 442c is a circular arc surface. For example, in the unfolded state, the upper surface 442a of the free end 442 of the metal support sheet 44 can be a flat surface.
