Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular to electronic devices and screen support components thereof. Background Art

[0002] In today's intelligent information age, users are using mobile devices more frequently and in increasingly diverse scenarios. Currently, most portable smart mobile devices have screen sizes under 7 inches. Compared to tablets and laptops, these devices have limited display area and a limited user experience.

[0003] The emergence of flexible screens effectively solves this problem. By bending or curling, a large screen can be stored in a small body, making it easy for users to carry. At the same time, the small screen can be used as a normal mobile phone, and when switched to the large screen, it can be used for news reading and social chatting. It can also enhance the user's gaming experience, greatly enriching user usage scenarios.

[0004] However, current electronic devices with flexible screen structures often require support members at the coiled position to ensure proper support for the flexible screen. While these supports can provide the necessary support for the flexible screen, they can also have negative consequences. For example, if the electronic device is dropped, it is likely to impact one of its four sides or corners, potentially causing the flexible screen to break at the coiled position, impairing its performance or even rendering the entire flexible screen useless. Summary of the Invention

[0005] The present application provides an electronic device and a screen support assembly thereof to solve the technical problem of how to improve the drop resistance of the flexible screen while maintaining good support for the flexible screen.

[0006] In a first aspect, an embodiment of the present application provides a screen support assembly, comprising:

[0007] Supporting body;

[0008] A guide assembly, comprising a bracket and a rotator, the rotator being rotatably connected to the bracket, the rotator being rotatable relative to the support body about its own rotation axis and being configured to contact a winding position of the flexible screen, so that the flexible screen extends from one side of the support body around the guide assembly to the other side of the support body;

[0009] The elastic component is used to movably connect the bracket with the supporting body so that when the flexible screen impacts the rotating body, the bracket moves relative to the supporting body driven by the rotating body, and the elastic component absorbs the impact force between the flexible screen and the rotating body.

[0010] On the other hand, an embodiment of the present application provides an electronic device, including a shell assembly, a flexible screen and a screen support assembly as described above, the shell assembly including a first shell and a second shell, the first shell and the second shell being movable relative to each other along a first direction, the flexible screen wraps around the side of the guide assembly of the screen support assembly and contacts the rotating body, and one end of the flexible screen is relatively fixed to the first shell, and the other end is movable within the shell assembly, the screen support assembly is relatively fixed to the second shell, and when the first shell and the second shell move relative to each other along the first direction, part of the structure of the flexible screen is subsequently extended from or retracted into the shell assembly.

[0011] In the embodiment of the present application, the rotating body of the guide assembly is in contact with the winding position of the flexible screen to support the flexible screen. Since the elastic assembly can absorb the impact force between the flexible screen and the rotating body, when the electronic device using the screen support assembly falls, the impact force of the external force acting on the flexible screen can be effectively buffered, thereby achieving the effect of improving the anti-fall performance. In addition, since the rotating body can rotate around its own rotation axis relative to the supporting body, the part of the flexible screen that is wound around the rotation axis can move smoothly, thereby improving the flexibility of the flexible screen's telescopic movement, so as to reduce the squeezing force on the rotating body during the flexible screen's telescopic movement, which is conducive to maintaining the relaxation of the elastic assembly and improving the buffering effect provided by the elastic assembly when the flexible screen is hit by external force.

[0041] (5) Conventional laptop and / or palmtop radiotelephone transceivers, etc.

[0042] See also Figure 1 and Figure 2 The electronic device 100 provided in the embodiment of the present application can be a mobile phone or a tablet computer, which is not limited here.

[0043] The electronic device 100 includes a housing assembly 10 , a flexible screen 20 and a screen support assembly 30 .

[0044] The shell assembly 10 forms a receiving cavity 10a, and the flexible screen 20 is connected to the shell assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), and both the circuit board and the battery may be arranged in the receiving cavity 10a of the shell assembly 10. The circuit board may integrate the processor, power management module, storage unit, baseband chip, etc. of the electronic device 100. The flexible screen 20 is communicatively connected to the processor, and the battery can power the flexible screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module (not shown), which is communicatively connected to the circuit board, and the battery can power the camera module. It will be understood that the electronic device 100 of the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices 100. In the embodiment of the present application, a mobile phone is taken as an example for illustration.

[0045] The housing assembly 10 includes a first housing 12 and a second housing 14, which are capable of relative movement in a first direction. Specifically, in this embodiment, the first housing 12 and the second housing 14 are slidably connected. In other words, the first housing 12 is capable of sliding relative to the second housing 14. For example, one of the first housing 12 and the second housing 14 may be provided with a slide rail, and the other may slide along the slide rail, so that the first housing 12 and the second housing 14 can move in a telescopic manner relative to each other.

[0046] The flexible screen 20 is connected to the first shell 12 and the second shell 14. As the first shell 12 and the second shell 14 move relative to each other, part of the structure of the flexible screen 20 is extended from or retracted into the shell assembly 10 to adjust the extended length of the flexible screen 20.

[0047] Furthermore, the first housing 12 can slide relative to the second housing 14 along the first direction to a folded position and an unfolded position. Figure 1 and Figure 3 As shown, when the first housing 12 is in the folded position, the electronic device 100 has a relatively small size and is easy to carry. Figure 2 and Figure 4 As shown, when the first housing 12 is in the unfolded position, the electronic device 100 can obtain a relatively large display area, thereby obtaining a large-screen display visual experience, thereby improving the user experience of the electronic device 100. Therefore, through this configuration, the display area of ​​the flexible screen 20 (hereinafter referred to as the display interface 20a) can be adjusted by the relative sliding and extension of the first housing 12 and the second housing 14.

[0048] It should be noted that the flexible screen 20, as a component used for display or touch control in the electronic device 100, has a display area. The display area refers to the area corresponding to the maximum display screen of the flexible screen 20. In other words, when the first shell 12 and the second shell 14 slide and retract relative to each other, when the first shell 12 is in the unfolded position, that is, when the display interface 20a is at its maximum, the display interface 20a is the same as the display area. Because the first shell 12 and the second shell 14 slide and retract relative to each other, part of the display area of ​​the flexible screen 20 is contained inside and not exposed, so this part does not show a display screen. The display interface 20a refers to the part of the display area that is exposed between the first shell 12 and the second shell 14. Then, when the display interface 20a is lit or displays a screen, the content displayed on the display interface 20a can be observed from the outside of the electronic device 100.

[0049] It is understood that in the embodiments of the present application that follow, expressions such as the retracted position, the extended position, and similar expressions all refer to the relative positions of the first housing 12 and the second housing 14. For simplicity, expressions such as "the first housing 12 is in the retracted position" or "when in the retracted position" refer to the first housing 12 being in the retracted position relative to the second housing 14, and expressions such as "the first housing 12 is in the extended position" or "when in the extended position" refer to the first housing 12 being in the extended position relative to the second housing 14.

[0050] Combine Figure 3 and Figure 4As shown, the flexible screen 20 may include a fixed end 202 and a free end 204 disposed opposite each other. The fixed end 202 is disposed on the first housing 12 and is fixed relative to the position of the first housing 12. When the first housing 12 is in the collapsed position, the free end 204 of the flexible screen 20 is accommodated within the housing assembly 10, thereby partially concealing the structure of the flexible screen 20 within the housing assembly 10. The portion of the flexible screen 20 concealed within the housing assembly 10 is not used for display. In other words, movement of the first housing 12 relative to the second housing 14 can cause at least a portion of the flexible screen 20 to be deployed within the second housing 14 or retracted within the housing assembly 10.

[0051] It is understood that in the embodiments of the present application, the relative fixed positions of two objects means that the two objects cannot produce relative movement under normal circumstances. The two objects that are relatively fixed in position can be physically directly connected or indirectly connected through an intermediate structure. Taking the fixed end 202 and the first shell 12 as an example, the relative fixed positions of the fixed end 202 and the first shell 12 can be directly in contact with the first shell 12, such as by using threaded fasteners or clamping to achieve direct fixation of the fixed end 202 and the first shell 12, or the fixed end 202 can be indirectly fixed to the first shell 12 through structures such as an adhesive layer, an intermediate connecting plate, etc.

[0052] In some embodiments, when the first shell 12 is in the folded position, the fixed end 202 exposed outside the shell assembly 10 is roughly rectangular, and its size can be 4.5 inches to 7 inches, which is comparable to the size of the display screen of a general smartphone, so that the electronic device 100 is easy to carry and more convenient to use.

[0053] Continue reading Figure 3 and Figure 4 As shown, the second shell 14 includes a back cover 141 and an outer frame 142. When in the unfolded position, the back cover 141 covers the free end 204 of the flexible screen 20. The outer frame 142 serves as the border of the electronic device 100. It can not only enhance the overall aesthetic appearance of the electronic device 100, but also support or protect the internal structure of the electronic device 100. The material of the outer frame 142 can be plastic, metal, or glass. In some embodiments, the outer frame 142 can include a metal part and a plastic part coated on the outer layer of the metal part, so as to utilize the metal part to provide good support performance. At the same time, the plastic part can enhance the drop resistance of the electronic device 100.

[0054] Furthermore, the back cover 141 can be provided with a light-transmitting area, and the portion of the flexible screen 20 housed in the shell assembly 10 in the folded position can also be used for display, so that the user can view the information displayed on the flexible screen 20 from the light-transmitting area, thereby expanding the use scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 does not need to be provided with a front camera, and a rear-mounted camera module can be used to achieve functions such as selfies and video calls. The light-transmitting area can be made of transparent glass, or it can be formed by an opening in the back cover 141. During the movement of the first shell 12 toward the unfolded position relative to the second shell 14, the portion of the flexible screen 20 housed in the shell assembly 10 is gradually unfolded from the shell assembly 10, so that the side of the electronic device 100 facing away from the back cover 141 has a relatively large display area, and then the user can obtain a large-screen display experience.

[0055] like Figure 3 and Figure 4 As shown, the screen support assembly 30 is fixed relative to the second housing 14 and is used to support the rolled-up position of the flexible screen 20. Therefore, when the first housing 12 moves relative to the second housing 14 toward the extended position, the first housing 12 pulls the fixed end 202 of the flexible screen 20 toward a side away from the screen support assembly 30, while the free end 204 of the flexible screen 20 approaches the screen support assembly 30. Guided by the screen support assembly 30, the flexible screen 20 gradually unfolds from the housing assembly 10. Correspondingly, when the first housing 12 moves relative to the second housing 14 toward the retracted position, the fixed end 202 of the flexible screen 20 approaches the screen support assembly 30, while the free end 204 of the flexible screen 20 moves away from the screen support assembly 30. Guided by the screen support assembly 30, the flexible screen 20 retracts into the housing assembly 10.

[0056] The screen support assembly 30 moves relative to the first shell 12 together with the second shell 14 , so that during the telescopic movement of the flexible screen 20 , the screen support assembly 30 can always provide good support for the winding position of the flexible screen 20 .

[0057] Combine Figure 3 and Figure 6 As shown, a driving mechanism 40 is provided in the housing assembly 10 of the electronic device 100. Specifically, the driving mechanism 40 is provided in the receiving cavity 10a of the housing assembly 10 and is used to drive the first housing 12 and the second housing 14 to move relative to each other, so that the second housing 14 drives the flexible screen 20 to be extended from or retracted into the housing assembly 10.

[0058] In some embodiments, the driving mechanism 40 includes a driving wheel 41, a traction belt 42 and a support wheel 43. The traction belt 42 is wound around the driving wheel 41 and the support wheel 43. When the driving wheel 41 rotates, the support wheel 43 supports the traction belt 42 and can rotate under the drive of the traction belt 42, and the traction belt 42 is used to drive the flexible screen 20 to be extended from the shell assembly 10 or put into the shell assembly 10. It should be noted that the driving wheel 41 can be connected to the output shaft of the driving motor, so that the driving motor provides driving force to realize the rotation of the driving wheel 41. In some embodiments, a reduction gear set can be provided between the output shaft of the driving motor and the driving wheel 41 to increase the transmission ratio, so that a larger rotational torque can be activated at the driving wheel 41, thereby increasing the driving force of the flexible screen 20.

[0059] Continue reading Figure 3 and Figure 6 As shown, the support wheel 43 is disposed at the end of the second housing 14 away from the first housing 12. When the first housing 12 is in the retracted position, the free end 204 of the flexible screen 20 passes over the support wheel 43. The support wheel 43 can limit the bending radius of the flexible screen 20 to an appropriate range to prevent damage to the flexible screen 20 caused by a too small bending radius. Of course, the support wheel 43 can also prevent the flexible screen 20 from being too thick due to an excessively large bending radius.

[0060] In some embodiments, the support wheel 43 can be a rotating shaft structure with protruding teeth, the traction belt 42 is engaged with the support wheel 43, and the portion of the flexible screen 20 near the free end 204 is connected to the traction belt 42, thereby achieving a linkage between the flexible screen 20 and the traction belt 42. Therefore, when the driving mechanism 40 drives the first housing 12 to slide relative to the second housing 14, the portion of the flexible screen 20 on the traction belt 42 moves with the traction belt 42 and is extended from or retracted into the shell assembly 10.

[0061] In other embodiments, the first shell 12 and the second shell 14 are connected to the driving mechanism 40 and move relative to each other under the drive of the driving mechanism 40. Specifically, the driving mechanism 40 has a fixed part and a movable part. When the driving mechanism 40 is working, the movable part can move relative to the fixed part. The fixed part is connected to the first shell 12, and the movable part is connected to the second shell 14, and is used to drive the first shell 12 to move relative to the second shell 14. The driving mechanism 40 may include a motor-screw structure. For example, the driving mechanism 40 includes a stepper motor, a screw and a nut. The stepper motor is fixed relative to the first shell 12 and is used to drive the screw to rotate. The screw and the nut are threaded together, so that when the screw rotates, the screw can be threaded to drive the nut to move. In this embodiment, the nut can be fixed to the second shell 14, so that when the screw thread drives the nut to move, the second shell 14 moves relative to the first shell 12. In this embodiment, a gear reduction mechanism can also be provided between the output end of the stepper motor and the screw.

[0062] In other embodiments, the drive mechanism 40 may include a gear and a rack, with the drive motor rotating the gear so that the gear engages the transmission rack. In this embodiment, one of the drive motor and the rack is fixed relative to the first housing 12, and the other is fixed relative to the second housing 14. Thus, when the gear engages the transmission rack and moves, the second housing 14 can move relative to the first housing 12.

[0063] The driving mechanism 40 may further include a telescopic cylinder, and the second housing 14 may move relative to the first housing 12 by utilizing the telescopic movement of the telescopic rod of the telescopic cylinder.

[0064] The structure of the driving mechanism 40 is not limited here, as long as it can achieve relative movement between the first shell 12 and the second shell 14 in the first direction so that the flexible screen 20 can be extended from or retracted into the shell assembly 10.

[0065] It should be noted that in the electronic device 100 of the present application, the relative movement of the first housing 12 and the second housing 14 can also be achieved manually. Specifically, when using the manual method, the user only needs to grasp the first housing 12 and the second housing 14 and move them away from each other to place the second housing 14 in the extended position. Accordingly, when the first housing 12 is in the extended position, if the electronic device 100 needs to be folded, it is only necessary to move the first housing 12 and the second housing 14 toward each other.

[0066] Combine Figures 7 to 9 The screen support assembly 30 includes a support body 31, a guide assembly 32 and an elastic assembly 33. The guide assembly 32 includes a bracket 321 and a rotating body 322. The rotating body 322 is rotatably connected to the bracket 321. The rotating body 322 can rotate relative to the support body 31 around its own rotation axis. Figure 15 As shown, the flexible screen 20 wraps around the side of the guide assembly 32 of the screen support assembly 30 and contacts the rotating body 322, so that the rotating body 322 provides support for the winding position of the flexible screen 20 and can guide the flexible screen 20 when the flexible screen 20 moves in an extension and contraction manner relative to the shell assembly 10.

[0067] Specifically, based on the contact between the flexible screen 20 and the rotating body 322, the rotating body 322 can rotate around its own rotation axis relative to the supporting body 31, so that when the flexible screen 20 is extended from or retracted into the shell assembly 10, the flexible screen 20 will drive the rotating body 322 to rotate, so that the flexible screen 20 can move smoothly and retract, and the guide assembly 32 can maintain the supporting effect on the winding position of the flexible screen 20.

[0068] like Figure 8 As shown, the bracket 321 is movably connected to the support body 31 via the elastic component 33. Specifically, the bracket 321 can move relative to the support body 31 within the range of elastic deformation. When the flexible screen 20 impacts the rotating body 322, the bracket 321 moves relative to the support body 31 driven by the rotating body 322. The elastic component 33 absorbs the impact force between the flexible screen 20 and the rotating body 322. Therefore, when the electronic device 100 using this screen support assembly 30 falls, the impact force applied to the flexible screen 20 by external forces can be effectively buffered, thereby achieving the effect of improving the drop resistance.

[0069] It should be noted that since the rotating body 322 can rotate around its own rotation axis relative to the supporting body 31, the part of the flexible screen 20 that is wound around the rotating axis can move smoothly, reducing the squeezing force on the rotating body 322 during the telescopic movement of the flexible screen 20, so as to facilitate the elastic component 33 to maintain the relaxation of the flexible screen 20 through the guide component 32. In this way, when the flexible screen 20 is impacted by external force, the elastic component 33 can absorb the external force impact, reduce the impact force between the flexible screen 20 and the rotating body 322, and make the flexible screen 20 not easy to break.

[0070] Continue reading Figure 8 As shown, the support body 31 is provided with an air avoidance groove 311, and part of the structure of the rotating body 322 is accommodated in the air avoidance groove 311, and the rotating body 322 is spaced apart from the groove wall of the air avoidance groove 311, so as to utilize the air avoidance groove 311 to provide the rotating body 322 with a movable space relative to the support body 31, which is conducive to maintaining the compactness between the rotating body 322 and the support body 31, and at the same time, avoiding interference between the structures during the rotation of the rotating body 322 relative to the support body 31.

[0071] In some embodiments, the support body 31 defines a mounting slot 312, and the elastic component 33 is positioned within the mounting slot 312 and in elastic contact with the walls of the mounting slot 312. Placing the elastic component 33 within the mounting slot 312 effectively ensures the stability of the elastic component 33. Furthermore, the elastic contact between the elastic component 33 and the walls of the mounting slot 312 allows the bracket 321 to float relative to the support body 31, thereby absorbing the impact force between the flexible screen 20 and the rotating body 322 when impacted by external forces, thereby reducing the risk of damage to the flexible screen 20.

[0072] The groove wall of the mounting groove 312 includes a bottom wall and a side wall. Figure 10 and Figure 11 As shown, the groove wall of the mounting groove 312 perpendicular to the thickness direction of the support body 31 defines the bottom wall 312a of the mounting groove 312. Correspondingly, the side walls 312b (312c, 312d) of the mounting groove 312 are groove walls perpendicular to the bottom wall 312a of the mounting groove 312. It should be noted that the aforementioned perpendicularity is not limited to an angle of 90°, and also includes angles of 85° to 95°, for example.

[0073] In some embodiments, the bottom wall 312a of the mounting groove 312 may also be set at an acute angle to the thickness direction of the support body 31, for example, the bottom wall 312a of the mounting groove 312 is set at 15°, 20°, 30°, 50°, 55° or 80° to the thickness direction of the support body 31. In this embodiment, the elastic contact between the elastic component 33 and the groove wall of the mounting groove 312 can still be used to achieve buffering of the guide component 32 to improve the drop resistance of the flexible screen 20. There is no limitation on the spatial position of the groove wall of the mounting groove 312 relative to the support body 31, as long as it can adapt to the installation requirements of the elastic component 33 and enable the elastic component 33 to elastically connect the rotating body 322 in contact with the flexible screen 20 to the support body 31.

[0074] Combine Figure 11 and Figure 12 As shown, the elastic component 33 includes a spring piece 331 , and the spring piece 331 includes a main body 3311 and an elastic portion 3312 . The elastic portion 3312 is connected to the main body 3311 and is used to contact the side wall of the installation groove 312 .

[0075] In this embodiment, the bracket 321 is relatively fixed to the main body 3311, so that the elastic contact between the elastic part 3312 connected to the main body 3311 and the side wall of the installation groove 312 is utilized to enable the rotating body 322 connected to the bracket 321 to float relative to the supporting body 31, so that when the flexible screen 20 is hit by external force, the elastic part 3312 can absorb the impact force, reduce the impact force between the rotating body 322 and the flexible screen 20, reduce the chance of damage to the flexible screen 20, and improve the drop resistance of the flexible screen 20.

[0076] Combine Figures 11 to 13 As shown, in some embodiments, the elastic component 33 includes a spring 332, one end of the spring 332 contacts the spring piece 331, and the other end contacts the bottom wall 312a of the mounting groove 312, and the main body 3311 can move axially along the spring 332 in the mounting groove 312 and maintain contact with the bracket 321 under the elastic force of the spring 332.

[0077] The screen support assembly 30 also includes a limiter 34 connected to the support body 31. The limiter 34 is used to limit the movement range of the bracket 321 in the mounting groove 312 along the thickness direction of the support body 31, so that the rotating body 322 connected to the bracket 321 can move relative to the support body 31 within an appropriate range, so as to maintain the supporting stability of the rotating body 322 on the flexible screen 20.

[0078] Combine Figure 12 and Figure 17 As shown, the limiting member 34 is movably provided through the bracket 321 and the main body 3311 . The limiting member 34 has a limiting end 34 a . Under the elastic force of the spring 332 , the main body 3311 holds the bracket 321 against the limiting end 34 a .

[0079] In some embodiments, the bracket 321 includes a linkage portion 3211 and a rotation connection portion 3212. The linkage portion 3211 is elastically connected to the support body 31 via the spring piece 331, and the rotation connection portion 3212 is rotationally matched with the rotating body 322, so that the rotating body 322 can rotate relative to the support body 31.

[0080] The stopper 34 may be a screw, in which case the stopper end 34a of the stopper 34 is the tail end of the screw. Using a screw as the stopper 34 not only facilitates connection between the stopper 34 and the support body 31, but also allows the movement of the bracket 321 within the mounting slot 312 to be adjusted by rotating the stopper 34.

[0081] Furthermore, if Figure 12As shown, the bracket 321 defines a first through-hole 321a, the main body 3311 defines a second through-hole 331a, and the stopper 34 is disposed through the first and second through-holes 321a, 331a. The diameters of the first and second through-holes 321a, 331a are both larger than the diameter of the stopper 34. This allows the stopper 34 to position the bracket 321 while allowing the main body 3311 and bracket 321 to move within the mounting slot 312 in a direction perpendicular to the stopper 34, allowing the elastic portion 3312 to effectively provide a cushioning effect.

[0082] The spring 332 is sleeved on the limiting member 34 and can move telescopically along the limiting member 34. The limiting member 34 can guide the spring 332 to facilitate the stability of the telescopic movement of the spring 332.

[0083] In other embodiments, the limit member 34 may also be a limit rod or a limit protrusion provided on the side wall 312b (312c, 312d) of the mounting groove 312. The structure of the limit member 34 is not limited here, as long as it can constrain the movement stroke of the bracket 321 in the mounting groove 312 to control the rotating body 322 to a position that provides stable support for the flexible screen 20.

[0084] Combine Figure 13 and Figure 14 As shown, the spring piece 331 includes at least two elastic parts 3312, which are respectively in elastic contact with the side walls 312b (312c, 312d) on different sides of the mounting groove 312, so as to achieve a buffering effect in multiple directions. Figure 13 As shown, the spring piece 331 includes three elastic parts 3312, and the three elastic parts 3312 are respectively connected to the three sides of the main body 3311. Figure 14 As shown, the elastic piece 331 includes two elastic portions 3312 , and the two elastic portions 3312 are respectively connected to two opposite sides of the main body 3311 .

[0085] Combine Figures 15 to 17 As shown, the rotating body 322 and the bracket 321 are rotatably connected via a bearing 323. It can be understood that in an embodiment in which the bracket 321 includes a linkage portion 3211 and a rotation connection portion 3212, the rotation connection portion 3212 is connected to the bearing 323 to be rotatably connected to the rotating body 322 via the bearing 323.

[0086] A first silicone sleeve 324 is provided on the outside of the bearing 323, and a sleeve connection portion 322a is provided at the end of the rotating body 322, which is sleeved on the first silicone sleeve 324. When the flexible screen 20 is impacted by an external force, even if the flexible screen 20 generates an impact force on the rotating body 322, the first silicone sleeve 324 can effectively buffer the impact force on the rotating body 322 during the process of transmitting the impact force to the rotating body 322 through the bracket 321 to the bearing 323, thereby at least partially absorbing the impact force between the flexible screen 20 and the rotating body 322, thereby reducing the risk of the flexible screen 20 breaking. In other words, the drop resistance of the flexible screen 20 is improved.

[0087] Furthermore, at least one of the inner wall and the outer wall of the first silicone sleeve 324 is provided with an annular groove 324a, so that when the first silicone sleeve 324 is squeezed, the area near the annular groove 324a can adapt to larger deformation, thereby enabling the first silicone sleeve 324 to better play a buffering role.

[0088] The hardness of the first silicone sleeve 324 is 70D to 80D, for example, 70D, 73D, 75D, 77D, or 80D. The first silicone sleeve 324 of appropriate hardness can provide a cushioning effect while ensuring that the rotating body 322 can provide sufficient support to support the flexible screen 20, preventing the rotating body 322 from becoming loose relative to the supporting body 31 during the flexible screen 20's telescopic movement, which could affect the stability of the flexible screen 20's telescopic movement.

[0089] In some embodiments, a buffer structure may also be provided between the rotating body 322 and the flexible screen 20. For example, the screen support assembly 30 includes a second silicone sleeve, which is provided on the rotating body 322 at a position for contacting the flexible screen 20. Thus, the second silicone sleeve can be used to support the flexible screen 20 while also providing a buffering effect. That is, when the flexible screen 20 is impacted by external force, the second silicone sleeve can alleviate the impact force between the flexible screen 20 and the rotating body 322, so that the flexible screen 20 is not easily damaged.

[0090] The hardness of the second silicone sleeve is 70D to 80D, for example, 70D, 73D, 75D, 77D, or 80D. The second silicone sleeve of appropriate hardness can provide a cushioning effect while ensuring that the rotating body 322 can provide sufficient support to support the flexible screen 20, preventing the rotating body 322 from becoming loose relative to the supporting body 31 during the flexible screen 20's telescopic movement, which would affect the stability of the flexible screen 20's telescopic movement.

[0091] It should be noted that the rotating body 322 can be made of silicone or plastic.

[0092] In some embodiments, in the guide assembly 32 of the screen support assembly 30, the number of rotating bodies 322 can be one, or two or more. When two or more rotating bodies 322 are provided, these rotating bodies 322 are coaxially arranged on the support body 31 to uniformly support the winding position of the flexible screen 20. Specifically, the two ends of each rotating body 322 are respectively connected to the corresponding elastic component 33 through the bracket 321, so that the elastic component 33 can be used to achieve a movable connection with the support body 31, thereby supporting and guiding the flexible screen 20. When the flexible screen 20 is impacted, the impact force can be transmitted to the support body 31 through the elastic component 33, so that the elastic component 33 can be used to absorb the impact force between the flexible screen 20 and the rotating body 322, so that the flexible screen 20 is not easily damaged, thereby improving the overall anti-fall performance of the electronic device 100.
