Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] With the explosive growth of electronic devices such as smartphones or tablets, electronic devices have more and more functions. The different sizes of the display screens of electronic devices will result in different user experiences of related functions of electronic devices. The display area of ​​the display screens of electronic devices is getting larger and larger, but when the display screen area is large, the overall size of the electronic device will be larger, which is inconvenient to carry. With the development of display technology, flexible display modules can be processed and manufactured. Flexible display modules include flexible display screens. Compared with traditional screens, flexible display screens have significant advantages, for example, flexible display screens have the characteristics of being bendable and flexible. Flexible display screens can be applied to foldable electronic devices. Foldable electronic devices include a housing and a rotating shaft device. The two housings can rotate relative to each other around the rotating shaft device to unfold or fold. The flexible display screen is covered on the two housings. When the two housings are unfolded to the same plane, the flexible display screen is in an unfolded state and has a larger display area. When the two housings are folded against each other, the flexible display screen is in a folded state, and the electronic device has a smaller volume. However, during the folding or unfolding process of the foldable electronic device, the parts inside the electronic device may collide or rub and make abnormal noises, affecting the user experience of the electronic device. Summary of the invention

[0003] 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 of the electronic device.

[0004] A first aspect of the present application provides an electronic device, which includes a flexible display screen and a hinge device.

[0005] The rotating shaft device is arranged on the backlight side of the flexible display screen. The rotating shaft device includes an axle 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. Along the width direction of the axle seat, the first swing arm and the second swing arm are respectively arranged on both sides of the axle seat. The first swing arm and the second swing arm can be rotatably connected to the axle 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 arranged between the door panel assembly and the flexible display screen. The metal support sheet includes an opposite 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 the free end is in a free state relative to the second door panel. The isolation gasket is connected to the metal support sheet. Along the length direction of the axle seat, the isolation gasket covers at least part of the free end. The isolation gasket isolates the second door panel from the free end.

[0006] In the electronic device of the embodiment of the present application, the metal support sheet can isolate the flexible display screen from the structural parts in the rotating shaft device, for example, the flexible display screen can be isolated from the shaft seat, the swing arm assembly and the door panel assembly of the rotating shaft device, thereby reducing the possibility of structural damage to the flexible display screen caused by the impact of the structural parts of the rotating shaft device during the folding or unfolding process. The metal support sheet can be folded or unfolded with the door panel assembly. The metal support sheet is provided with an isolation gasket. During the folding or unfolding of the metal support sheet, the isolation gasket moves with the metal support sheet. The isolation gasket can cover at least part of the free end, so that the isolation gasket isolates the free end from the second door panel, so that the free end and the second door panel are not easy to contact each other, and then during the folding or unfolding of the metal support sheet, the free end is not easy to be scratched with the structural parts of the second door panel, reducing the possibility of abnormal noise caused by direct scratching between the free end and the structural parts of the second door panel. In addition, the method of arranging the isolation gasket on the metal support sheet makes the process difficulty of realizing mutual combination between the isolation gasket and the metal support sheet relatively low, which is conducive to reducing costs.

[0007] In a possible implementation, the isolation gasket covers the entire free end along the length direction of the shaft seat.

[0008] 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.

[0009] In a possible implementation, the shaft device further includes a shielding sheet. Along the length direction of the shaft seat, two ends of the isolation gasket are connected to the shielding sheet. The shielding sheet shields the free end.

[0010] 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 beneficial to further reduce the possibility of scratching the free end with external structural parts.

[0011] In a possible implementation, the isolation gasket includes a first connecting section, a bent connecting section, and a second connecting section. The first connecting section is arranged on a side of the metal support sheet facing the flexible display screen. The second connecting section is arranged on a side of the metal support sheet facing the second door panel. The bent connecting section connects the first connecting section and the second connecting section. The first connecting section, the bent connecting section, and the second connecting section enclose a receiving space. The free end is plugged into the receiving space.

[0012] 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.

[0013] In a possible implementation, the number of the second connecting segments is more than two, and the more than two second connecting segments are arranged at intervals along the length direction of the shaft seat.

[0014] The configuration of the second connecting section in this embodiment is beneficial to saving the usage of isolation gaskets and reducing production costs.

[0015] In a possible implementation manner, 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.

[0016] The manner in which the bent connecting section and the second connecting section are arranged correspondingly is conducive to further saving the usage of the isolation gasket and reducing the production cost.

[0017] In a possible implementation manner, 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.

[0018] The arrangement of the first connecting section is conducive to further saving the usage of isolation gaskets and reducing production costs.

[0019] 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.

[0020] 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.

[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. The first connecting section covers the entire surface of the metal support sheet facing the flexible display screen.

[0022] 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 reduce the possibility of the metal support sheet directly scratching the flexible display screen.

[0023] In a possible implementation, a portion of the second connecting section is located between the second door panel and the metal support sheet, and another portion is located between the metal support sheet and the swing arm assembly and between the metal support sheet and the axle seat.

[0024] The second connection section can isolate the metal support sheet and the swing arm assembly, thereby reducing the possibility of the metal support sheet contacting with the swing arm assembly and causing a scratch or abnormal noise between the metal support sheet and the swing arm assembly. At the same time, the second connection section can isolate the metal support sheet and the shaft seat, thereby reducing the possibility of the metal support sheet contacting with the shaft seat and causing a scratch or abnormal noise between the metal support sheet and the shaft seat.

[0025] In a possible implementation manner, the isolation gasket is a flexible gasket.

[0026] When the isolation gasket and the second door panel slide relative to each other, the isolation gasket can effectively buffer the gap, reduce the possibility of abnormal noise between the isolation gasket and the second door panel, and reduce the possibility of scratches on the second door panel caused by contact and scratching between the isolation gasket and the second door panel. The first connecting section between the metal support sheet and the flexible display screen can play a buffering role, so that the flexible display screen and the first connecting section can be in flexible contact, which is conducive to further reducing the possibility of structural damage to the flexible display screen.

[0027] In a possible implementation manner, the isolation gasket is an insulating gasket.

[0028] The portion of the isolation gasket located between the flexible display screen and the metal support sheet (eg, the first connecting section) can play an insulating role, thereby reducing the possibility of electrical signals being transmitted between the flexible display screen and the metal support sheet through the metal support sheet.

[0029] In a 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 connection surface. The transition connection surface connects the upper surface and the lower surface. The lower surface is a curved surface. The thickness of the free end decreases in a direction away from the connection end.

[0030] When the free end moves relative to the second door panel, the free end is not 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.

[0031] In a possible implementation, the transition surface is a curved surface. The lower surface, the transition surface and the upper surface are smoothly transitioned, so that there is no sharp edge on the free end, which reduces the possibility that the sharp edge of the free end locally squeezes the isolation gasket and causes the isolation gasket to be damaged, thereby reducing the possibility that the isolation gasket fails to be isolated due to the damage of the isolation gasket and the free end can directly scratch the second door panel.

[0032] In a possible implementation manner, the connecting end is bonded to the first door panel.

[0033] The connecting end and the first door panel are bonded together, so that there is no need to set additional connecting parts such as screws, clips or rivets between the connecting end and the first door panel. On the one hand, this is beneficial to reduce the complexity of the connecting structure between the connecting end and the first door panel and reduce the difficulty of assembly. On the other hand, there is no need to set a corresponding connecting structure, such as a hole, between the connecting end and the first door panel, which is beneficial to reduce the processing difficulty of the connecting end and the first door panel and improve the structural integrity of the connecting end and the first door panel.

[0034] In a possible implementation manner, the isolation gasket is bonded to the metal support sheet.

[0035] The isolation gasket and the metal support sheet are bonded together, so that there is no need to set additional connecting parts such as screws, clips or rivets between the isolation gasket and the metal support sheet. On the one hand, this helps to reduce the complexity of the connecting 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.

[0036] A second aspect of the present application provides an electronic device, which includes a flexible display screen and a hinge device.

[0037] The rotating shaft device is arranged on the backlight side of the flexible display screen. The rotating shaft device includes an axle seat, a swing arm assembly, a door panel assembly and a metal support sheet. The swing arm assembly includes a first swing arm and a second swing arm. Along the width direction of the axle seat, the first swing arm and the second swing arm are respectively arranged on both sides of the axle seat. The first swing arm and the second swing arm can be rotatably connected to the axle 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 arranged between the door panel assembly and the flexible display screen. The metal support sheet includes a connecting end and a free end opposite to each other. 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 the free end 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 surface and the lower surface. The lower surface is a curved surface. The thickness of the free end decreases in the direction away from the connecting end.

[0038] In this embodiment, the free end of the metal support sheet can be in 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, so that friction resistance is generated 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, when the free end and the second door panel move relative to each other, the free end is not likely to locally squeeze the second door panel, so that the relative movement process between the free end and the second door panel is relatively smooth and gentle, and thus, during the relative movement process between the free end and the second door panel, it is not likely to produce abnormal noise due to friction between the two, which is conducive to improving the quietness of the electronic device during the switching process between the unfolded state and the folded state, improving 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 is conducive to reducing costs.

[0039] 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

[0078] The electronic device in the embodiment of the present application can be called user equipment (UE) or terminal, etc. For example, the electronic device can be a 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 embodiment of the present application, the form of the terminal device is not specifically limited.

[0079] In the embodiment of the present application, Figure 1 The structure of the electronic device 10 is schematically shown. Figure 1 As shown, the electronic device 10 is a handheld device with a wireless communication function as an example for description. The handheld device with a wireless communication function can be, for example, a foldable electronic device 10. The electronic device 10 can be a foldable mobile phone including a foldable flexible display screen.

[0080] Figure 2The structure of the electronic device 10 in a half-folded state is schematically shown. Figure 3 The structure of the electronic device 10 in the folded state is schematically shown. Figures 1 to 3 As shown, the electronic device 10 includes a housing 20. The housing 20 includes at least two frames 30 and a hinge device 40 as an example for explanation. The two frames 30 are respectively located on both 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 fastener locking. The two frames 30 can be rotated and folded. When the two frames 30 are close to each other and stacked on each other, the electronic device 10 is in a folded state. When the two frames 30 move away from each other from the stacked state and the two frames 30 rotate until they cannot rotate, the electronic device 10 is in an unfolded state. The process of the two frames 30 from the folded state to the unfolded state is an unfolding process, and the process from the unfolded state to the folded state is a folding process. Exemplarily, when the electronic device 10 is in the folded state, the two frames 30 are stacked to present a two-layer structure. Exemplarily, the frame 30 may include a middle frame or a back cover. The frame 30 may be connected to the hinge device 40 through the middle frame.

[0081] Figure 4 The partially exploded structure of the electronic device 10 is schematically shown. Figure 1 and Figure 4 As shown, the electronic device 10 also includes a flexible display screen 50. The flexible display screen 50 is covered on the housing 20. The hinge device 40 is arranged 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 by hand to execute the corresponding operation instruction.

[0082] The flexible display screen 50 itself has a bendable property and can be folded after being acted upon by an external force. When the electronic device 10 is in the unfolded state, the display portion of the flexible display screen 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 arranged corresponding to the two frames 30. The third display area 53 may be arranged corresponding to the hinge device 40.

[0083] When the two frames 30 are in the folded state, the display unit is in the 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 state, for example, the third display area 53 can be bent into a water drop shape.

[0084] When the two frames 30 are in the unfolded state, the display unit is in the unfolded state, and 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 larger display area in the unfolded state.

[0085] The two frames 30 of the electronic device 10 may be provided with printed circuit boards (PCBs) and electronic devices, respectively. The electronic devices are provided on the printed circuit boards. For example, the electronic devices may include but are not limited to processors, memories or camera modules. The printed circuit board in one frame 30 may be used as a main board.

[0086] In the related technology, Figure 5 The partial cross-sectional structure of the electronic device 10 in the related art in the unfolded state is schematically shown. Figure 6 The partial structure of a metal support sheet in the related art is schematically shown. Figure 7 The partial cross-sectional structure of the electronic device 10 of the related art in a folded state is schematically shown. Figures 5 to 7As shown, since the structural strength of the flexible display screen 50 itself is relatively low, the flexible display screen 50 is likely to be structurally damaged when it is locally impacted by external structural parts. Therefore, a metal support sheet 44 is provided between the hinge device 40 and the flexible display screen 50. The metal support sheet 44 can separate the hinge device 40 from the flexible display screen 50, so that the metal support sheet 44 plays a buffering role between the hinge device 40 and the flexible display screen 50, effectively improving the impact resistance of the flexible display screen 50, and helping to reduce the possibility of structural damage to the flexible display screen 50 caused by local impact of the structural parts in the hinge device 40. One end of the metal support sheet 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. In the process of folding and unfolding the electronic device 10, the hinge device 40 can drive the metal support sheet 44 to bend or unfold. During the bending or unfolding process of the metal support sheet 44, the free end 442 of the metal support sheet 44 will slide relative to the corresponding door panel, so that the sharp edge S of the free end 442 is likely to rub against the structural parts on the sliding path and produce abnormal noise. In order 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 hinge device 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 friction between the free end 442 of the metal support sheet 44 and other structural parts during sliding, the protective patch M needs to be provided on all structural parts on the door panel that may be scratched by the free end 442. Since the door panel itself has a complex structure and a large number of structural parts, the process of providing the protective patch M on the door panel is difficult and costly.

[0087] 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 and the corresponding door panel. During the folding and unfolding process of the electronic device 10, the metal support sheet 44 is not easy to be scratched with other structural parts to produce abnormal noise. At the same time, the difficulty of combining the isolation gasket and the metal support sheet 44 is low, which is conducive to reducing costs.

[0088] Figure 8 The partial cross-sectional structure of the electronic device 10 in the unfolded state is schematically shown. Fig. 9 The partial cross-sectional structure of the electronic device 10 in the folded state is schematically shown. Figure 8 and Fig. 9 As shown, the electronic device 10 of the embodiment of the present application includes a rotating shaft device 40. The rotating shaft device 40 includes an axle seat 41, a swing arm assembly 42, a door panel assembly 43, a metal support sheet 44 and an isolation gasket 45.

[0089] The shaft seat 41 can shield other structural parts on the rotating shaft device 40, so that the electronic device 10 has a neat and beautiful appearance. When the two frames 30 rotate relative to the rotating shaft device 40, the position of the shaft seat 41 can remain relatively fixed. The shaft seat 41 can provide an installation basis for related structural parts in the rotating shaft device 40. The shaft seat 41 can be a bar 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.

[0090] 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 arranged on both sides of the shaft seat 41 along the width direction Y of the shaft seat 41. The first swing arm 421 and the second swing arm 422 can be rotatably connected to the shaft seat 41. The first swing arm 421 and the second swing arm 422 can be respectively 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 shaft seat 41, so that the first swing arm 421 and the second swing arm 422 can switch between the folded position and the unfolded position.

[0091] 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 arranged on both sides of the shaft seat 41 along the width direction Y of the shaft seat 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 seat 41, the first door panel 431 and the second door panel 432 respectively follow the first swing arm 421 and the second swing arm 422 to rotate relative to the shaft seat 41, so that the first door panel 431 and the second door panel 432 can switch between the folded position and the 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 an 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.

[0092] The metal support sheet 44 is arranged between the door panel assembly 43 and the flexible display screen 50. The metal support sheet 44 is in a non-connected state with the flexible display screen 50. The metal support sheet 44 includes a connecting end 441 and a free end 442. Along the width direction Y of the shaft seat 41, the connecting end 441 and the free end 442 are arranged opposite to each other. 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 the free end 442 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 sheet 44 will be folded under the action of the first door panel 431 and the second door panel 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 be unfolded 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 collapse and deformation of the third display area 53. 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, and the free end 442 of the metal support sheet 44 is in a free state, so that the free end 442 of the metal support sheet 44 moves 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.

[0093] For example, the material of the metal support sheet 44 may be, but not limited to, stainless steel or titanium alloy. The shape of the metal support sheet 44 in the unfolded state may be, but 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 .

[0094] 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 move relative to the second door panel 432.

[0095] 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. This helps to reduce the friction resistance between the isolation gasket 45 and the second door panel 432 during the sliding of the isolation gasket 45 relative to the second door panel 432, thereby improving the smoothness of the folding or unfolding process of the electronic device 10 and enhancing the user experience.

[0096] In the electronic device 10 of the embodiment of the present application, the metal support sheet 44 can isolate the flexible display screen 50 from the structural parts in the hinge device 40, for example, the flexible display screen 50 can be isolated from the shaft seat 41, the swing arm assembly 42 and the door panel assembly 43 of the hinge device 40, thereby reducing the possibility of the flexible display screen 50 being impacted by the structural parts of the hinge device 40 and being damaged during the folding or unfolding process. The metal support sheet 44 can be folded or unfolded following the door panel assembly 43. The metal support sheet 44 is provided with an isolation gasket 45. During the folding or unfolding process of the metal support sheet 44, the isolation gasket 45 moves following the metal support sheet 44. The isolation gasket 45 can cover at least a portion of the free end 442, so that the isolation gasket 45 isolates the free end 442 from the second door panel 432, making it difficult for the free end 442 to contact the second door panel 432, and further, during the folding or unfolding process of the metal support sheet 44, the free end 442 is not easy to rub against the structural parts 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 parts of the second door panel 432. In addition, the method of arranging the isolation gasket 45 on the metal support sheet 44 makes the process difficulty of realizing mutual combination between the isolation gasket 45 and the metal support sheet 44 relatively low, which is conducive to reducing costs.

[0097] In some achievable ways, Fig.10The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.10 As shown, the isolation pad 45 extends continuously along the length direction X of the shaft seat 41. The length of the isolation pad 45 can be less than the length of the free end 442, so that in the length direction X of the shaft seat 41, the isolation pad 45 can cover part of the free end 442. The shape of the isolation pad 45 in the expanded state can be, but is not limited to, a rectangle. The length direction of the isolation pad 45 is the same as the length direction X of the shaft seat 41.

[0098] In some achievable ways, Fig.11 The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.12 for Fig.11 Enlarged view of the middle W. Fig.11 and Fig.12 As shown, 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 improving the isolation effect, which is conducive to reducing the possibility of contact and scratching between any position of the free end 442 and the second door panel 432.

[0099] In some examples, Fig.13 The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.13 As shown, the rotating shaft device 40 also includes a shielding piece 46. Along the length direction X of the shaft seat 41, the shielding pieces 46 are connected to both ends of the isolation gasket 45. The shielding piece 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 piece 46 can cover the end surface of the free end 442. The isolation gasket 45 and the shielding piece 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 the external structural parts.

[0100] Exemplarily, the material of the isolation pad 45 may be the same as that of the shielding sheet 46. The isolation pad 45 and the shielding sheet 46 are an integrally formed structure.

[0101] See also Fig.13As shown, 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 arranged on the side of the metal support sheet 44 facing the flexible display screen 50. For example, the first connecting section 451 can be connected to the surface of the metal support sheet 44 facing the flexible display screen 50. The second connecting section 452 is arranged on the side of the metal support sheet 44 facing the second door panel 432. For example, the second connecting section 452 can 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 are enclosed to form a receiving space. The free end 442 of the metal support sheet 44 is plugged 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 is conducive to reducing the processing difficulty of the isolation gasket 45 and reducing the processing cost.

[0102] For some examples, see Fig.11 and Fig.12 As shown, along the length direction X of the shaft seat 41, the first connecting section 451, the bent connecting section 453 and the second connecting section 452 all extend continuously, that is, the number of the first connecting section 451, the bent connecting section 453 and the second connecting section 452 is one. The length of the first connecting section 451 is equal to the length of the bent connecting section 453. The length of the bent connecting section 453 is equal to the length of the second connecting section 452. Exemplarily, the shape of the isolation gasket 45 in the unfolded state can be a rectangle. The length direction of the isolation gasket 45 is the same as the length direction X of the shaft seat 41.

[0103] Fig.14 The partial structure of the connection state of the metal support sheet 44 and the isolation gasket 45 is schematically shown. Fig.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 connection surface 442c. The transition connection surface 442c connects the upper surface 442a and the lower surface 442b. The upper surface 442a of the free end 442 is arranged to face 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 bending connecting section 453 can cover the transition connection surface 442c. Exemplarily, the transition connection surface 442c of the free end 442 can be a plane. Exemplarily, the transition connection surface 442c of the free end 442 can be a curved surface. The bending connecting section 453 is arc-shaped. For example, the transition connection surface 442c can be a circular arc surface, and the bending connecting section 453 can be an arc-shaped.

[0104] 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 beneficial to reduce the space occupancy rate of the isolation gasket 45 in the thickness direction of the metal support sheet 44, and reduce the possibility of affecting the lightweight design of the electronic device 10 due to the large thickness of the isolation gasket 45.

[0105] In some examples, Fig.15 The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.15 As shown, 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 corresponding to the escape space on the free end 442 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 correspondingly 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 not set 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 of this embodiment is conducive to saving the use of the isolation gasket 45 and reducing the production cost. Exemplarily, along the length direction X of the shaft seat 41, the first connecting segment 451 and the bent connecting segment 453 can both extend continuously, that is, the number of the first connecting segment 451 and the bent connecting segment 453 is one each.

[0106] For example, Fig.16 The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.16 As shown, 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 and the second connecting sections 452 are arranged in correspondence is conducive to further saving the use of the isolation gasket 45 and reducing the production cost. Exemplarily, 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. Exemplarily, 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.

[0107] For example, Fig.17 The partial structure of the metal support sheet 44 and the isolation gasket 45 in a bent state is schematically shown. Fig.18 The partial structure of the metal support sheet 44 and the isolation gasket 45 in the unfolded state is schematically shown. Fig.17 and Fig.18 As shown, 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 bending 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 bending connecting segments 453. The number of the bending 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, a first connecting segment 451, a bending connecting segment 453 and a second connecting segment 452 are connected to each other. The arrangement of the first connecting segment 451 is conducive to further saving the use of the isolation gasket 45 and reducing the production cost.

[0108] In some examples, Fig.19 The partial cross-sectional structure of the electronic device 10 in the folded state is schematically shown. Fig.19 As shown, the first connecting section 451 is disposed on the side of the metal support sheet 44 facing the flexible display screen 50. The first connecting section 451 can isolate the metal support sheet 44 and the flexible display screen 50, so that the first connecting section 451 can protect the flexible display screen 50, which is conducive to reducing the possibility of the metal support sheet 44 directly scratching the flexible display screen 50.

[0109] Exemplarily, 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 unfolded metal support sheet 44, the orthographic projection area of ​​the first connecting segment 451 on the metal support sheet 44 may be greater than the orthographic projection area of ​​the second connecting segment 452 on the metal support sheet 44. Exemplarily, the first connecting segment 451 may cover the surface of the metal support sheet 44 except the connecting segment, or the first connecting segment 451 may cover the entire surface of the metal support sheet 44 facing the flexible display screen 50, which is conducive to maintaining a relatively large area of ​​the first connecting segment 451 and improving the protection performance.

[0110] 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, and 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 shaft seat 41. Therefore, the second connecting section 452 may isolate the metal support sheet 44 from the swing arm assembly 42, thereby reducing the possibility of the metal support sheet 44 contacting with the swing arm assembly 42 and causing a scratch or abnormal noise between the metal support sheet 44 and the swing arm assembly 42. At the same time, the second connecting section 452 may isolate the metal support sheet 44 from the shaft seat 41, thereby reducing the possibility of the metal support sheet 44 contacting with the shaft seat 41 and causing a scratch or abnormal noise between the metal support sheet 44 and the shaft seat 41. 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 protection performance.

[0111] 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 may be smaller than the orthographic projection area of ​​the second connecting segment 452 on the metal support sheet 44.

[0112] 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 .

[0113] In some achievable ways, the isolation gasket 45 is a flexible gasket. The rigidity of the isolation gasket 45 is less than the rigidity 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 play an effective buffering role, reduce the possibility of abnormal noise between the isolation gasket 45 and the second door panel 432, and also reduce the possibility of scratches on the second door panel 432 caused by the contact and scratching 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 the rigidity of the metal support sheet 44. The first connecting section 451 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.

[0114] In some achievable ways, the isolation pad 45 is an insulating pad. The isolation pad 45 has insulating isolation 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 section 451) can play an insulating isolation role, reducing the possibility of electrical signals being transmitted through the metal support sheet 44 between the flexible display screen 50 and the metal support sheet 44. The isolation pad 45 having insulating properties can also have good flexibility. It is not easy for the flexible display screen 50 and the isolation pad 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 scratches on the isolation pad 45.

[0115] In some examples, the isolation pad 45 may be a plastic film. For example, the material of the isolation pad 45 may include, but is not limited to, polyethylene terephthalate, polyvinyl chloride, polyethylene, polypropylene, or polystyrene. For example, the isolation pad 45 may be a mylar sheet.

[0116] In some examples, an insulating material may be sprayed on the metal support sheet 44 using a surface spraying process to form an isolation gasket 45 having insulating properties.

[0117] In some achievable ways, Fig. 20 The partial structure of the metal support sheet 44 and the isolation gasket 45 in the assembled state is schematically shown. Fig. 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 a curved surface. In the direction away from the connection end 441, the thickness of the free end 442 decreases. The isolation gasket 45 covers at least a portion of the lower surface 442b. In the process of the free end 442 moving relative to the second door panel 432, the free end 442 is not easy to form a local extrusion on the isolation gasket 45, reducing the possibility of stress concentration on the isolation gasket 45 causing cracks or damage to the isolation gasket 45. Exemplarily, the lower surface 442b of the free end 442 is an arc surface. Exemplarily, the thickness of the isolation gasket 45 is uniform.

[0118] In some examples, the transition surface 442c of the free end 442 is a curved surface. The lower surface 442b, the transition surface 442c and the upper surface 442a are smoothly transitioned, so that there is no sharp edge on the free end 442, reducing the possibility that the sharp edge of the free end 442 partially squeezes the isolation gasket 45 and causes the isolation gasket 45 to be damaged due to the sharp edge of the free end 442, thereby reducing the possibility that the isolation gasket 45 fails to be isolated due to the damage of the isolation gasket 45 and the free end 442 can directly scratch the second door panel 432. Exemplarily, the transition surface 442c of the free end 442 is an arc surface. For example, the transition surface 442c is a circular arc surface.

[0119] In some examples, when the metal support sheet 44 is in the expanded state, the upper surface 442a of the free end 442 may be a plane.

[0120] In some achievable ways, 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 parts such as screws, snaps or rivets are required between the connection end 441 and the first door panel 431, thereby, on the one hand, reducing the complexity of the connection structure between the connection end 441 and the first door panel 431 and reducing the difficulty of assembly; on the other hand, there is no need to set a corresponding connection structure, such as a hole, on the connection end 441 and the first door panel 431, which is conducive to reducing the processing difficulty of the connection end 441 and the first door panel 431 and improving the structural integrity of the connection end 441 and the first door panel 431.

[0121] In some achievable ways, the isolation gasket 45 is bonded to the metal support sheet 44. The isolation gasket 45 can be pre-processed and manufactured separately, and then the isolation gasket 45 is fixed to a predetermined position of the metal support sheet 44 by assembly. During the assembly process, an adhesive can be coated on the isolation gasket 45 or the metal support sheet 44, and then the isolation gasket 45 and the metal support sheet 44 are bonded. The adhesive can be, for example, adhesive glue. The isolation gasket 45 and the metal support sheet 44 are bonded in a bonding manner, so that no additional connecting parts such as screws, buckles or rivets are required between the isolation gasket 45 and the metal support sheet 44, thereby, on the one hand, reducing the complexity of the connection structure between the isolation gasket 45 and the metal support sheet 44 and reducing the difficulty of assembly; on the other hand, there is no need to set corresponding connection structures, such as holes, on the isolation gasket 45 and the metal support sheet 44, which is conducive to reducing the processing difficulty of 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.

[0122] Fig.21 The partial cross-sectional structure of the electronic device 10 in the unfolded state is schematically shown. Fig. 22 The partial cross-sectional structure of the electronic device 10 in a folded state is schematically shown. Fig.23 The partial structure of the metal support sheet 44 is schematically shown. Fig.24 for Fig.23 Enlarged view of P in the middle. Figure 21 to Figure 24 As shown, an embodiment of the present application also 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 screen 50 and a hinge device 40. A metal support sheet 44 is arranged between the door panel assembly 43 and the flexible display screen 50. The metal support sheet 44 includes a connecting end 441 and a free end 442 opposite to each other. 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 the free end 442 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 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 a curved surface. In the direction away from the connecting end 441, the thickness of the free end 442 decreases.

[0123] In this embodiment, the free end 442 of the metal support sheet 44 can be in 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, so that friction resistance is generated between the free end 442 and the second door panel 432. Since the lower surface 442b of the free end 442 is a curved surface with a relatively smooth transition, when the free end 442 and the second door panel 432 move relative to each other, the free end 442 is not likely to locally squeeze the second door panel 432, so that the relative movement process between the free end 442 and the second door panel 432 is relatively smooth and gentle, and thus, during the relative movement process between the free end 442 and the second door panel 432, it is not likely to produce abnormal noise due to the scratching between the two, which is conducive to improving the quietness of the electronic device 10 during the switching process between the unfolded state and the folded state, improving the user experience, and also helping to reduce the possibility of scratches on the second door panel 432 caused by the free end 442. In addition, the processing difficulty of the free end 442 of this embodiment is relatively low, and there is no need to set an isolation structure on the second door panel 432, which is conducive to reducing costs.

[0124] In some achievable ways, the transition connection surface 442c of the free end 442 is a curved surface. The lower surface 442b, the transition connection surface 442c and the upper surface 442a are smoothly transitioned, so that there is no sharp edge on the free end 442. On the one hand, it is conducive to further reducing the possibility of scratching and generating abnormal noise during the relative movement between the free end 442 and the second door panel 432; on the other hand, it is conducive to further reducing the possibility of scratches on the second door panel 432 caused by the free end 442; on the other hand, it is conducive to reducing the possibility of the free end 442 scratching or scratching the flexible display screen 50 during the folding and unfolding of the metal support sheet 44. Exemplarily, the lower surface 442b of the free end 442 can be an arc surface. The transition connection surface 442c of the free end 442 is an arc surface. For example, the transition connection surface 442c is a circular arc surface. Exemplarily, the upper surface 442a of the free end 442 of the metal support sheet 44 in the unfolded state can be a plane.
