[0002] With the development and popularization of electronic devices such as smart phones, flexible screen assemblies have been gradually applied to electronic devices. In related technologies, flexible screen assemblies are usually applied to rollable mobile phones. However, when the flexible screen assembly switches between the long-term curled and flattened states, the flexible screen assembly will be damaged, thereby shortening the service life of the flexible screen assembly.

The first state is that the movable part is connected to the main body part, and the second state is that there is a movable space between the movable part and the main body part. The flexible screen assembly is disposed adjacent to the movable part and the flexible screen assembly can move within the movable space; and

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 The first structure diagram of the electronic device provided by the embodiment of the present application, Figure 2 is Figure 1 The partial structure diagram of the electronic device shown. The electronic device such as Figure 1The electronic device 20 can be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cellular phone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a pendant device, a headset or earpiece device, a device embedded in glasses or other device worn on a user's head, or other wearable or micro device), a television, a computer monitor not including an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or a vehicle), a device that implements the functions of two or more of these devices, or other electronic device. In Figure 1 an exemplary configuration, the electronic device 20 is a portable device such as a cellular phone, a media player, a tablet computer, or other portable computing device. Other configurations can be used for the electronic device 20 if desired. Figure 1 The examples are merely exemplary.

[0032] The electronic device 20 can include a housing assembly such as the housing assembly 100, and the housing assembly 100 can be formed of plastic, glass, ceramic, fiber composite material, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The housing assembly 100 can be formed using a one-piece configuration in which some or all of the housing assembly 100 is machined or molded into a single structure, or can be formed using multiple structures (e.g., an inner frame structure, one or more structures forming an outer housing surface, etc.).

[0033] Among them, the housing assembly 100 can be in a regular shape, such as a cuboid structure or a rounded rectangular structure. The housing assembly 100 can include a main body part such as the main body part 110 and a movable part such as the movable part 120. The main body part 110 and the movable part 120 can be movably connected so that the movable part 120 can be switched between a first state and a second state. When the movable part 120 is in the first state, the movable part 120 is connected to the main body part 110, which can be achieved by abutting or adjacent means. Of course, it can also be achieved by other connection means, such as snap connection or clamping connection. When the movable part 120 is in the second state, there is a movable space between the movable part 120 and the main body part 110, and this movable space can provide a movement space for a flexible screen assembly such as the flexible screen assembly 200. For example, the flexible screen assembly 200 can move through this movable space to expand a part of the flexible screen assembly 200 outside the housing assembly 100 or retract a part of the flexible screen assembly 200 inside the housing assembly 100. Among them, the movable part 120 can be switched between the second state and the first state by manually pulling the movable part 120; or the movable part 120 can be driven to switch between the second state and the first state by an electronic drive. It should be noted that the above is only an example of the state switching method of the movable part 120 and should not be construed as a limitation on the state switching method of the movable part 120.

[0034] It can be understood that if this movable space is not provided, the flexible screen assembly 200 may come into contact with the housing assembly 100 and generate friction during movement, which may cause damage to the flexible screen assembly 200; if a gap is directly provided around the flexible screen assembly 200 to isolate the flexible screen assembly 200 from the housing assembly 100, it will cause waste of the space of the housing assembly 100, and additional shielding components need to be provided on the appearance surface to shield the gap between the housing assembly 100 and the flexible screen assembly 200, which will undoubtedly increase the volume of the housing assembly 100. In the embodiment of the present application, by separating the housing assembly 100 into the main body part 110 and the movable part 120, when the flexible screen assembly 200 moves, the movable part 120 can be in the second state. At this time, there is a certain distance between the movable part 120 and the flexible screen assembly 200, and then the flexible screen assembly 200 is moved. In this way, the risk of friction between the telescopic movement of the flexible screen assembly 200 and the housing assembly 100 can be directly avoided, and thus the wear during the movement of the flexible screen assembly 200 can be reduced, and the service life of the flexible screen assembly 200 can be extended. After the telescopic movement is completed, the movable part 120 can be connected to the main body part 110 so that the movable space cannot be seen from the appearance surface, and other objects can also be prevented from entering the housing assembly 100 through this movable space.

[0035] Please refer to Figure 3 、 Figure 4 and Figure 5 ,Figure 3 The Figure 2 schematic cross-sectional structure diagram of the electronic device shown along the P1-P1 direction, Figure 4 The Figure 2 schematic cross-sectional structure diagram of the electronic device shown along the P2-P2 direction, Figure 5 The Figure 2 schematic cross-sectional structure diagram of the electronic device shown along the P3-P3 direction. The movable part 120 can be movably connected to the main body part 110 through a connecting member such as the connecting member 300. For example, the main body part 110 can include a first side such as the first side 111 and a second side such as the second side 112, and the first side 111 and the second side 112 are arranged opposite to each other. For example, the first side 111 is located at the top of the electronic device 20 or at the top of the display area of the electronic device 20, and the second side 112 is located at the bottom of the electronic device 20 or at the bottom of the display area of the electronic device 20.

[0036] Among them, the first side 111 is provided with a first sliding groove 1111 and a first limiting groove 1112 that communicate with each other. The connecting member 300 can include a first connecting rod 310 and a first sliding block 320. The first connecting rod 310 is connected to the movable part 120 (such as one end of the movable part 120), and the first connecting rod 310 is accommodated in the first sliding groove 1111. The first connecting rod 310 can slide in the first sliding groove 1111, so that the movable part 120 can be switched between a first state and a second state; the first sliding block 320 is accommodated in the first limiting groove 1112, and the size of the first sliding block 320 is smaller than the size of the first sliding groove 1111 to limit the movement of the first sliding block 320 in the first limiting groove 1112 and prevent it from moving into the first sliding groove 1111, thereby limiting the movement distance of the movable part 120.

[0037] The first sliding block 320 can be connected to the groove wall of the first limiting groove 1112 through an elastic member such as a spring. The elastic member can generate elastic deformation, so that there is a pre-tightening force between the first sliding block 320 and the elastic member. Furthermore, the movable part 120 has a certain pre-tightening force in the second state or the first state, which can improve the user experience of using the movable part 120. In order to enable the movable part 120 to maintain in the movable state and the first state, in the embodiment of the present application, a first limiting member is provided on the first sliding block 320, and a second limiting member is provided on the groove wall of the first limiting groove 1112. The first limiting member can cooperate with the second limiting member to limit the first sliding block 320, so that the first sliding block 320 is maintained at a preset position, and further the movable part 120 is maintained in the first state or the second state.

[0038] For example, the first slider 320 may have a cuboid structure. The first slider 320 includes a first side, a second side, a third side, and a fourth side that are interconnected. The first side and the third side are oppositely arranged, and the second side and the fourth side are oppositely arranged. The first limiting member may be provided on the first side. The second side may be connected to the first link 310, and the fourth side may be connected to the elastic member. The first limiting member may be a clamping groove. For example, the first side includes a bottom wall, a first side wall, and a second side wall. The bottom wall is connected to the side walls to form the clamping groove. The first side wall and the second side wall are inclined with respect to each other, and the bottom wall is connected between the first side wall and the second side wall. The second limiting member on the groove wall of the first limiting groove 1112 may be a clamping member, and the clamping member may be clamped in the clamping groove to fix the first side. The clamping member may be a spring piece, and the outer surface of the clamping member is an arc surface to provide a deformation space for the clamping member.

[0039] When the movable part 120 moves away from the main body part 110, the movable part 120 will pull the first link 310 and the first slider 320 to also move away from the main body part 110. During the movement of the first slider 320, the outer surface of the clamping member undergoes elastic deformation and slides out of the clamping groove from the bottom wall position of the clamping groove along the first side wall, so that the first side of the first slider 320 can be separated from the clamping groove, and further the movable part 120 can be separated from the main body part 110 by a certain distance to provide a movable space between the movable part 120 and the main body part 110. When the movable part 120 moves towards the main body part 110, the movable part 120 will push the first link 310 and the first slider 320 to also move towards the main body part 110. During the movement of the first slider 320, the outer surface of the clamping member undergoes elastic deformation and slides into the bottom wall position along the first side wall of the clamping groove, and the second side wall can limit the clamping member to clamp the clamping member in the clamping groove.

[0040] It should be noted that the first limiting member may also be provided on the third side, or the first side and the third side may both be provided with the first limiting member at the same time. In addition, the structure of the first slider 320 is not limited to a cuboid structure. For example, the first slider 320 may also be a spherical structure or other polyhedron structures, etc.

[0041] The second side 112 may be provided with a second sliding groove and a second limiting groove that communicate with each other. The connecting member 300 may include a second connecting rod and a second sliding block. The second connecting rod is connected to the movable portion 120 (such as the other end of the movable portion 120), and the second connecting rod is received in the second sliding groove. The second connecting rod can slide in the second sliding groove, so that the movable portion 120 can be switched between the first state and the second state; the second sliding block is received in the second limiting groove, and the size of the second sliding block is smaller than the size of the second sliding groove to limit the movement of the second sliding block in the second limiting groove and prevent it from moving into the second sliding groove, thereby limiting the movement distance of the movable portion 120. Wherein, the second sliding groove may have the same structure as the first sliding groove 1111, the second limiting groove may have the same structure as the first limiting groove 1112, the second connecting rod may have the same structure as the first connecting rod 3110, and the second sliding block may have the same structure as the first sliding block 320. Of course, the second sliding groove may also have a different structure from the first sliding groove 1111, the second limiting groove may also have a different structure from the first limiting groove 1112, the second connecting rod may also have a different structure from the first connecting rod 310, and the second sliding block may also have a different structure from the first sliding block 320.

[0042] In an embodiment of the present application, a third limiting member may also be provided on the second sliding block, and a fourth limiting member is provided on the groove wall of the second limiting groove. The third limiting member can cooperate with the fourth limiting member to limit the second sliding block, so that the second sliding block is held in a preset position, and further the movable portion 120 is held in the first state or the second state. The structure of the third limiting member may be the same as that of the first limiting member, and the structure of the fourth limiting member may be the same as that of the second limiting member. Of course, it is also possible that the structure of the third limiting member is different from that of the first limiting member and the structure of the fourth limiting member is different from that of the second limiting member.

[0043] Please continue to refer to Figure 3 , the electronic device 20 may further include a sealing member such as a sealing member 400. The sealing member 400 is provided on the inner surface of the movable portion 120, where the inner surface of the movable portion 120 refers to the side of the movable portion 120 close to the flexible screen assembly 200. The sealing member 400 may be made of a foam material, a rubber material or other materials. When the movable portion 120 is in the first state, the sealing member 400 can abut against the flexible screen assembly 200 to block the gap between the movable portion 120 and the flexible screen assembly 200 when the movable portion 120 is in the first state, thereby playing a role in sealing dust and some water vapor.

[0044] Please continue to refer to Figure 3 and Figure 5, the shaft 500 can be arranged on the main body 110. The shaft 500 is arranged between the first side 111 and the second side 112. For example, one end of the shaft 500 is connected to the first side 111, and the other end of the shaft 500 is connected to the second side 112. The flexible screen assembly 200 is sleeved on the shaft 500 and the flexible screen assembly 200 can move along the outer surface of the shaft 500. Wherein the shaft 500 is located on the non-display surface side of the flexible screen assembly 200, and the movable part 120 is located on the display surface side of the flexible screen assembly 200. It can be understood that during the process of the flexible screen assembly 200 moving along the outer surface of the shaft 500, the movable part 120 can be first made to be in the second state, and then the flexible screen assembly 200 can be made to move along the outer surface of the shaft 500, so that the display surface of the flexible screen assembly 200 will not be damaged due to direct contact and friction with the movable part 120.

[0045] Wherein, the projection of the movable part 120 on the flexible screen assembly 200 and the projection of the shaft 500 on the flexible screen assembly 200 at least partially overlap. The projection of the movable part 120 on the flexible screen assembly 200 refers to the projection when the projection direction is parallel to the main body 110, and the projection of the shaft 500 on the flexible screen assembly 200 refers to the projection when the projection direction is parallel to the main body 110. It can be understood that when the flexible screen assembly 200 is sleeved on the shaft 500, the flexible screen assembly 200 will form a bending area, and the movable part 120 is located at the corresponding position of the bending area. Moreover, the outer surface of the movable part 120 is flush with the outer surface of the main body part 211. For example, the part of the movable part 120 located on the display surface of the electronic device 20 is flush with the display surface of the main body part 211, which can improve the appearance beauty of the electronic device. It should be noted that the movable part 120 can also be located in the non-bending area of the flexible screen assembly 200.

[0046] Such as Figure 3As shown, the flexible screen assembly 200 of the embodiment of the present application may include a flexible display module 210 and a flexible support member 220. The flexible support member 220 is located on the non-display surface side of the flexible display module 210 and is used to support the flexible display module 210. It can be understood that the flexible support member 220 has a relatively high structural strength. On the one hand, it can support the flexible display module 210, improve the flatness of the flexible display module 210, so that the flexible display module 210 is not prone to collapse or wrinkle during the display process. On the other hand, the flexible support member 220 can also improve the overall strength of the flexible screen assembly 200 and protect the flexible screen assembly 200 from being easily damaged during the stretching process. Among them, the flexible display module 210 may be an OLED (Organic Light Emitting Diode) module. The OLED module may include a display substrate and a packaging material, and an organic light-emitting substance is encapsulated between the display substrate and the packaging material. A number of OLED units are included on the OLED module, and each OLED unit is electrically connected to the main board of the electronic device to achieve self-luminescence and display a picture. The flexible display module 210 may also be an LCD (Liquid Crystal Display) module. The LCD module may include a display substrate and a packaging material, and a liquid crystal material is encapsulated between the display substrate and the packaging material. The main board of the electronic device provides a voltage for the liquid crystal material, thereby changing the arrangement direction of the liquid crystal molecules. After the light projected by the backlight source acts together inside the LCD module, an image is formed in the display area to display a picture.

[0047] Combined with Figure 6 As shown, Figure 6 is the second structural schematic diagram of the electronic device provided by the embodiment of the present application. The flexible screen assembly 200 may include a narrow screen mode as Figure 1 shown and a wide screen mode as Figure 6 shown. In the narrow screen mode, the display area of the flexible screen assembly 200 is fixed; in the wide screen mode, the display area of the flexible screen assembly 200 can be expanded. For example, the flexible display module 210 may include a main body portion 211 and an extended portion 212. The main body portion 211 is fixedly connected to the housing assembly 100, and the extended portion 212 abuts against a shaft such as shaft 500 and the extended portion 212 can move along the outer surface of the shaft 500, so that the extended portion 212 can be deployed outside the housing assembly 100 or retracted into the housing assembly 100.

[0048] When the flexible screen assembly 200 is in the narrow screen mode or the wide screen mode, the main body part 211 is always fixed on the outer surface of the housing assembly 100 and is exposed outside the electronic device 20. At this time, the extension part 212 is in a retracted state, and at this time, the extension part 212 is hidden inside the housing assembly 100 and cannot be used to display information. Only the main body part 211 of the flexible screen assembly 200 is used for display; when the flexible screen is switched from the narrow screen mode to the wide screen mode, the user can pull the movable part 120 to move away from the main body part 110 (or a driving mechanism can be set to drive the movable part 120 to move), and then drive at least a part of the extension part 212 to gradually rotate out of the housing assembly 100 along the outer surface of the shaft 500. At this time, at least a part of the extension part 212 is exposed outside the housing assembly 100, realizing the switch from the narrow screen mode to the wide screen mode. The extension part 212 exposed outside can display information together with the main body part 211. Compared with only using the main body part 211 for information display, the display area can be increased. When the flexible screen assembly 200 is switched from the wide screen mode to the narrow screen mode, the extension part 212 can be gradually rotated into the housing assembly 100 along the outer surface of the shaft 500 in the direction close to the housing assembly 100 (the expansion or retraction of the flexible screen assembly 200 can be realized by manual driving or mechanical driving), so that at least a part of the extension part 212 is retracted into the housing assembly 100. After the switch is completed, the movable part 120 is pushed to move in the direction close to the main body part 110, so that the movable part 120 is connected to the main body part 110 (or the reciprocating movement of the movable part 120 can also be driven by a mechanical driving method).

[0049] The flexible support 220 may include a soft rubber connecting band, a metal sheet, etc. For example Figure 7 as shown Figure 7 is Figure 1Partial structural schematic diagram of the electronic device shown. The flexible support member 220 may include a soft glue connecting belt such as the soft glue connecting belt 221. The hardness (Shore A) of the soft glue connecting belt 221 is (60-75) degrees, such as 65 degrees, 68 degrees, 70 degrees or 75 degrees, etc. The soft glue connecting belt 221 may be made of rubber, silica gel, TPU (Thermoplastic polyurethanes), etc. The soft glue connecting belt 221 is disposed on the non-display surface of the extension portion 212. The soft glue connecting belt 221 may provide a flat bearing surface for the extension portion 212, so that the extension portion 212 can be unfolded flatly without wrinkles or depressions. Moreover, compared with rigid materials, the hardness of the soft glue connecting belt 221 used in the embodiments of the present application is between 60 degrees and 75 degrees, which can reduce the damage to the extension portion 212 during the movement of the soft glue connecting belt 221, thereby protecting the contact surface between the extension portion 212 and the soft glue connecting belt 221 from being easily worn. In addition, since the extension portion 212 often rubs against the shaft 500 during movement, the extension portion 212 is easily damaged. In the embodiments of the present application, by adding the soft glue connecting belt 221 to the extension portion 212 that needs to move, the friction force originally acting on the extension portion 212 can be transferred to the soft glue connecting belt 221, which can further protect the extension portion 212.

[0050] As Figure 8 shown, Figure 8 is Figure 7 The first partial structural schematic diagram of the flexible screen assembly and the shaft in the electronic device shown. The size of the soft glue connecting belt 221 is equal to the size of the extension portion 212. The projection of the soft glue connecting belt 221 on the flexible screen assembly 200 is located on the extension portion 212, so that the soft glue connecting belt 221 can cover the entire non-display surface of the extension portion 212, thereby protecting the entire extension portion 212. Compared with the related art, where the flexible screen is directly used as the stretching main body, in the present application, the soft glue connecting belt 221 is disposed on the extension portion 212, which can space the direct contact between the extension portion 212 and the shaft 500, thereby avoiding the wear of the non-display surface of the extension portion 212 caused by the direct friction between the non-display surface of the extension portion 212 and the outer surface of the shaft 500.

[0051] In some other embodiments, such as Figure 9 shown, Figure 9 is Figure 7The second partial structural schematic diagram of the flexible screen assembly and the shaft in the electronic device shown. The size of the soft glue connecting band 221 can also be larger than the size of the extended part 212. When the size of the soft glue connecting band 221 is larger than the size of the extended part 212, a part of the projection of the soft glue connecting band 221 on the flexible screen assembly 200 is located on the extended part 212, and a part is located outside the extended part 212. For example, it can be located on the main body part 211 or in the accommodating space of the housing assembly 100. For example, it can be used to connect a drive motor, and the drive motor drives the extended part 212 to unfold or retract by driving the part of the soft glue connecting band 221 located in the accommodating space of the housing assembly 100 to curl or stretch.

[0052] When a part of the soft glue connecting band 221 is located on the main body part 211, the outer surface of the side part of the soft glue connecting band 221 is flush with the outer surface of the side part of the main body part 211. For example, both the soft glue connecting band 221 and the main body part 211 are in a cuboid structure. The soft glue connecting band 221 can have four interconnected side parts, and the soft glue connecting band 221 has two opposite surfaces, and the two surfaces are connected to both sides of the four side parts to enclose a cuboid structure. Similarly, the main body part 211 can also have four interconnected side parts and opposite display surfaces and non-display surfaces. Among them, the soft glue connecting band 221 is arranged on the non-display surface of the main body part 211, and the outer surfaces of the four side parts of the soft glue connecting band 221 are flush with the outer surfaces of the four side parts of the main body part 211. The soft glue connecting band 221 can support the main body part 211, making the display surface of the main body part 211 flatter, and the soft glue connecting band 221 cannot be observed from the outside, maintaining the simplicity of the appearance of the flexible screen assembly 200.

[0053] As Figures 10 to 14 shown, Figure 10 is Figure 7 the first structural schematic diagram of the flexible screen assembly in the electronic device shown, Figure 11 is Figure 10 the structural schematic diagram of the first support sheet in the flexible screen assembly shown, Figure 12 is Figure 10 the partial structural schematic diagram of the first support sheet shown, Figure 13 is Figure 11 the sectional structural schematic diagram of the first support sheet along P4 - P4 shown, Figure 14 is Figure 11 the sectional structural schematic diagram of the first support sheet along P5 - P5 shown.

[0054] The flexible support member 220 may further include a first support sheet such as the first support sheet 222. The first support sheet 222 may be made of a metal material. For example, the first support sheet may be a steel sheet, an aluminum sheet, a copper sheet, etc. The first support sheet 222 is embedded inside the soft glue connection belt 221. For example, the soft glue connection belt 221 may be injection-molded on the first support sheet 222 so that the first support sheet 222 is wrapped inside the soft glue connection belt 221, thereby preventing the first support sheet 222 from directly contacting the flexible screen assembly 200 and achieving the purpose of protecting the flexible screen assembly 200.

[0055] In the initial state, the first support sheet 222 is in a first state, which is a state where at least a part of the first support sheet 222 does not contact the extension part 212. When the soft glue connection belt 221 and the extension part 212 move together to the surface of the shaft 500, an interaction force in the radial direction of the shaft 500 will be generated between the shaft 500 and the first support sheet 222, causing the first support sheet 222 to switch from the first state to a second state. The second state is a state where the first support sheet 222 is completely attached to the extension part 212. When the soft glue connection belt 221 and the extension part 212 continue to move, the soft glue connection belt 221 and the extension part 212 gradually move away from the surface of the shaft 500, and the interaction force between the shaft 500 and the first support sheet 222 gradually disappears. At this time, the first support sheet 222 gradually returns to its original state, that is, the first support sheet 222 switches from the second state to the first state.

[0056] Wherein, when the first support sheet 222 is in the first state, a part of the first support sheet 222 does not contact the extension part 212. For example, there may be a concave structure in the middle of the first support sheet 222, the two sides of the first support sheet 222 contact the extension part 212, and there is a gap between the middle of the first support sheet 222 and the extension part 212. It may also be that the first support sheet 222 has multiple concave structures, and there is a gap between the part of the first support sheet 222 with the concave structure and the extension part 212, and the other parts of the first support sheet 222 contact or are attached to the non-display surface of the extension part 212. When the first support sheet 222 is in the second state, due to the first support sheet 222 receiving an interaction force in the radial direction of the shaft 500, the first support sheet 222 deforms, and then a part of the first support sheet 222 that was not in contact with the extension part 212 originally is attached to the display surface of the extension part 212, so that the outer shape of the first support sheet 222 is consistent with the outer shape of the extension part 212, thereby ensuring that the flexible screen assembly 200 can be repeatedly unfolded and retracted according to a preset movement trajectory.

[0057] For example, the first support piece 222 may include a first side portion 2221, a second side portion 2222, and a recessed portion 2223. The recessed portion 2223 is located between the first side portion 2221 and the second side portion 2222. The first side portion 2221 is located at one end of the shaft 500, and the second side portion 2222 is located at the other end of the shaft 500. The groove portion 513 is located at the middle position of the shaft 500. The recessed portion 2223 is formed by bending from the display surface of the main body portion 211 towards the non-display surface of the main body portion 211. It can be understood that the structure of the first support piece 222 is similar to that of a tape measure. The cross-section of the first support piece 222 in the width direction of the electronic device 20 is an arc structure, and the bending direction of the first support piece 222 is away from the shaft 500. When the soft glue connecting band 221 moves along the outer surface of the shaft 500, the first support piece 222 can be deformed so that the recessed portion 2223 switches between a first bending state and a second bending state.

[0058] For example, in the initial state, the recessed portion 2223 is in the first bending state. The first bending state means that the recessed portion 2223 bends from the display surface of the main body portion 211 towards the non-display surface of the main body portion 211. When the soft glue connecting band 221 moves along the shaft 500, the soft glue connecting band 221 moving to the position of the shaft 500 will abut against the shaft 500. During this process, the first support piece 222 located inside the soft glue connecting band 221 can receive a radial force along the shaft 500 through the soft glue connecting band 221 and deform, so that the recessed portion 2223 switches from the first bending state to the second bending state, and the remaining parts of the first support piece that are not in contact with the shaft 500 remain unchanged, that is, in the first bending state. Among them, the second bending state means that the recessed portion 2223 bends from the non-display surface of the main body portion 211 towards the display surface of the main body portion 211, so that the bending direction of the first support piece 222 is the same as the radian of the shaft 500, thereby improving the fitting degree between the soft glue connecting band 221 and the shaft 500 and making the movement of the soft glue connecting band 221 smoother. When the soft glue connecting band 221 gradually moves outside or inside the housing assembly 100 along the outer surface direction of the shaft 500, the soft glue connecting band that was originally in contact with the shaft 500 gradually moves away from the shaft 500. At this time, the extrusion force of the shaft 500 on the first support piece 222 will also be gradually withdrawn, so that the recessed portion 2223 switches from the second bending state to the first bending state.

[0059] It can be understood that when the first support piece 222 is in a flattened state, the cross-sectional shape of the first support piece 222 is as Figure 13As shown, the first support piece 222 is concave in the flattened state. With just a little force applied to its back surface, it can deform and flip into a flat shape, making the shape of the first support piece 222 the same as that of the extension part 212. As a result, the extension part 212 can move along the surface of the shaft 500. Based on the structure of the first support piece 222, when the first support piece 222 receives a force in the radial direction of the shaft 500, it can deform and flip from the concave shape to the flat shape, as shown in Figure 14 shown; and it returns to its original concave state after the force in the radial direction of the shaft 500 is no longer received.

[0060] It should be noted that the structure of the first support piece 222 is not limited to this. For example, the first support piece 222 can have multiple concave portions 2223, which are arranged at intervals. One concave portion 2223 is bent from the display surface of the main body part 211 towards the non-display surface direction of the main body part 211. When the extension part moves to the shaft 500, when all or part of the concave portions 2223 receive a force in the radial direction of the shaft 500, they deform, causing the concave portions 2223 to bend from the non-display surface of the main body part towards the display surface of the main body part. At this time, the multiple concave portions 2223 switch from the first bending state to the second bending state. When the extension part 212 moves away from the shaft 500, the concave portions 2223 return to the state of bending from the display surface of the main body part 211 towards the non-display surface direction of the main body part 211.

[0061] It can be understood that if the first support piece 222 is a common flat rigid structure, when the first support piece 222 moves to the position of the shaft 500, due to the mutual force between the shaft 500 and the first support piece 222, the first support piece 222 will deform into a bent state and then fit the outer surface of the shaft 500. When the first support piece 222 leaves the position of the shaft 500, at this time, the mutual force between the shaft 500 and the first support piece 222 disappears. However, since the first support piece 222 is a flat rigid structure, without the action of other forces after deformation, it cannot return to the original flat state. For example, it will present the original bent state, which will also cause the extension part 212 to be uneven and affect the display effect of the electronic device 20. The first support piece 222 of the present application can switch between the first state and the second state, so that it switches from the first state to the second state when at the position of the shaft 500 (or at the bending position), and switches back from the second state to the first state when moving to other positions. That is, it can realize the free switching of the extension part 212 between the unfolded state and the retracted state, and can also make the extension part 212 remain flat in both the unfolded state and the retracted state, reducing the impact of the movement process of the extension part 212 on the display effect of the electronic device 20.

[0062] In some other embodiments, the first support piece 222 can also be directly disposed on the non-display surface of the extension part 212. The first support piece 222 can be directly adhered to the non-display surface of the extension part 212 by an adhesive such as double-sided tape or glue.

[0063] When the extension part 212 is located inside the housing assembly 100, a part of the first support piece 222 abuts against the shaft 500. For example, a part of the extension part 212 abuts against the surface of the shaft 500, and there is a gap between a part of the extension part 212 and the shaft 500 (it can be understood that a part of the extension part 212 does not touch the shaft 500). At this time, a part of the first support piece 222 abuts against the shaft 500, and another part of the first support piece 222 has a gap with the shaft 500. It should be noted that the structure of the first support piece 222 is not limited to this. For example, the first support piece 222 can be only disposed on the part of the extension part 212 that has a gap with the shaft 500, and not disposed on the other part of the extension part 212 that abuts against the shaft 500. At this time, the first support piece 222 is spaced from the shaft 500 and does not abut against the shaft 500.

[0064] When the extension part 212 is located outside the housing assembly 100, a part of the first support piece 222 abuts against the shaft 500. For example, a part of the extension part 212 abuts against the surface of the shaft 500, and there is a gap between a part of the extension part 212 and the shaft 500 (it can be understood that a part of the extension part 212 does not touch the shaft 500). At this time, a part of the first support piece 222 abuts against the shaft 500, and another part of the first support piece 222 has a gap with the shaft 500. It can be understood that at this time, a part of the extension part 212 is laid flat outside the housing assembly 100, and a part of the extension part 212 is sleeved on the surface of the shaft 500. It should be noted that the structure of the first support piece 222 is not limited to this. For example, when the extension part 212 is located outside the housing assembly 100, the first support piece 222 can be only disposed on the part of the extension part 212 that has a gap with the shaft 500, and not disposed on the other part of the extension part 212 that abuts against the shaft 500. At this time, the first support piece 222 is spaced from the shaft 500 and does not abut against the shaft 500.

[0065] The size of the first support piece 222 may be greater than or equal to the size of the extension part 212. When the size of the first support piece 222 is equal to the size of the extension part 212, the projection of the first support piece 222 on the flexible screen assembly 200 is located on the extension part 212, so that the first support piece 222 can cover the non-display surface of the entire extension part 212, thereby supporting the entire extension part 212. Compared with the related art, in which the flexible screen is directly used as the stretching body, in the embodiment of the present application, the first support piece 222 is provided on the extension part 212, which can space the extension part 212 from direct contact with the shaft 500, thereby avoiding the wear caused to the extension part 212 during the process of the non-display surface of the extension part 212 directly rubbing against the outer surface of the shaft 500. When the size of the first support piece 222 is greater than the size of the extension part 212, the projection of the first support piece 222 on the flexible screen assembly 200 is partly located on the extension part 212 and partly outside the extension part 212. For example, it may be located on the main body part 211 or in the accommodation space of the housing assembly 100.

[0066] When a part of the first support piece 222 is located on the main body part 211, the outer side surface of the side part of the first support piece 222 is flush with the outer side surface of the side part of the main body part 211. For example, both the first support piece 222 and the main body part 211 are in a cuboid structure. The first support piece 222 may have four interconnected side parts, and the first support piece 222 has two opposite surfaces, and the two surfaces are connected to both sides of the four side parts to enclose a cuboid structure. Similarly, the main body part 211 may also have four interconnected side parts and opposite display surfaces and non-display surfaces. The first support piece 222 is arranged on the non-display surface of the main body part 211, and the four outer side surfaces of the four side parts of the first support piece 222 are flush with the four outer side surfaces of the four side parts of the main body part 211. The first support piece 222 can support the main body part 211, making the display surface of the main body part 211 flatter, and the first support piece 222 cannot be observed from the outside, maintaining the simplicity of the appearance of the flexible screen assembly 200.

[0067] It should be noted that the first support piece 222 may not be located on the main body part 211. For example, Figure 15 as shown, Figure 15 which is a first partial structural schematic diagram of the first support piece and the second support piece provided by the embodiment of the present application. The flexible support 220 may further include a second support piece 223, and the second support piece 223 is located on the non-display surface of the main body part 211. The structure of the second support piece 223 is different from the structure of the first support piece 222. For example, the second support piece 223 is a straight structure and does not have an arc structure. The second support piece 223 can provide a flat bearing surface for the main body part 211. It should be noted that the structure of the second support piece 223 may be the same as that of the first support piece 222, which is convenient for processing.

[0068] It can be understood that to enable the flexible screen display module 210 in the stretching and bending area, the flexible screen display module 210 can continuously change from a flattened state to a bent state and then back to a flattened state according to the bent shape. Obviously, the materials that can achieve these two state transitions are generally flexible materials, and it is required that the materials must be in a stretched state, such as the various thin film materials in the flexible screen display module 210. However, if there is only a flexible material, in the stretching and bending part, when one end is in a stretched state, the flexible material cannot be pulled and drawn along the established bending trajectory. And the flexible screen display module 210 cannot be directly stressed in the stretched state because this is likely to cause damage to the flexible screen display module 210. Obviously, to enable the flexible screen display module 210 to expand and contract along the established trajectory at the bending position and ensure that the flexible screen display module 210 is not stressed alone, an attached rigid structure needs to be added in the bending area. However, if a general rigid structure is used, it is impossible to achieve repeated switching between the flattened state and the bent state. In the embodiment of the present application, by improving the structure of the first support piece 222, the first support piece 222 can be switched between the first bending state and the second bending state, thereby enabling the flexible screen to easily switch between the unfolded state and the recovered state.

[0069] It should be noted that the structure of the first support piece 222 is not limited to this. For example, the first support piece 222 can deform in the width direction of the electronic device 20, so that the first support piece 222 can be stretched during the movement on the outer surface of the shaft 500, thereby ensuring that the first support piece 222 can easily support the extended part 212 in the stretching and bending area and can achieve stretching and bending without the risk of damage during the movement along the outer surface of the shaft 500. It can be understood that if a rigid piece is directly provided on the non-display surface of the extended part 212, the rigid piece may break and be damaged due to insufficient tension when it moves to the position of the shaft 500. And if a rubber part or a spring-like elastic part is directly used, it may cause insufficient supporting force for the extended part 212 due to excessive elasticity, thereby resulting in poor phenomena such as wrinkles or depressions in the flexible screen assembly 200.

[0070] For example, as Figure 16 shown, Figure 16This is the second partial structural schematic diagram of the first support sheet and the second support sheet provided by the embodiments of the present application. All or part of the first support sheet 222 is provided with a plurality of mesh holes such as mesh hole 2224 to improve the deformability of the first support sheet 222. For example, an acidic etching solution can be used to etch the first support sheet 222 to etch a plurality of diamond-shaped mesh holes 2224 on the first support sheet 222, so that the first support sheet 222 has a diamond-shaped wire mesh structure. The diamond-shaped wire mesh structure can enable the first support sheet 222 to have the ability to stretch in the width direction and / or the length direction of the electronic device 20. When the first support sheet 222 moves in the width direction of the electronic device 20, the first support sheet 222 will receive the extrusion force applied by the shaft 500 and the tensile force along the width direction of the electronic device 20. Under the action of the extrusion force and the tensile force, it can deform. Compared with a rigid sheet, the first support sheet 222 of the embodiments of the present application can ensure that it will not break due to excessive tension during the movement process.

[0071] The mesh hole 2224 can be a regular shape, such as a diamond structure, a rectangular structure, etc., or the mesh hole 2224 can be an irregular shape. For example, the mesh hole 2224 of the embodiments of the present application is a diamond structure. For example, all or part of the first support sheet 222 can be formed into a diamond-shaped wire mesh structure. The advantage of the first support sheet 222 with a diamond-shaped wire mesh structure is that it has very good flexibility and has a great advantage in ensuring the flatness of the flexible screen component module, and its bending life is long.

[0072] Among them, when the size of the first support sheet 222 is equal to the size of the extension part 212, the first support sheet 222 can be processed into a diamond-shaped wire mesh structure; when the size of the first support sheet 222 is larger than the extension part 212, the part of the first support sheet 222 located on the non-display surface of the extension part 212 can be processed into a diamond-shaped wire mesh structure, and the other parts of the first support sheet 222 are flat rigid sheet structures and do not need to be etched with an etching solution. For example, the part of the first support sheet 222 located on the non-display surface of the main body part 211. It can be understood that the first support sheet 222 can include a first section and a second section. The first section is arranged on the non-display surface of the main body part 211 and is a complete rigid sheet structure with no mesh hole design on the surface. The second section is arranged on the non-display surface of the extension part 212, and the second section is provided with a plurality of mesh holes 2224, and the mesh holes 2224 are diamond structures so that the second section forms a diamond-shaped wire mesh structure. Since during the movement of the first support sheet 222, mainly the part of the first support sheet 222 located on the non-display surface of the extension part 212 is stressed, only part of the first support sheet 222 is processed into a diamond-shaped wire mesh structure. On the one hand, it ensures the deformability of the first support sheet 222, on the other hand, it can ensure the support strength of the entire first support sheet 222, and it can also reduce the manufacturing difficulty and cost.

[0073] Combined Figure 17 As shown Figure 17 is Figure 7 The second structural schematic diagram of the flexible screen assembly in the electronic device shown. The flexible screen assembly 200 may further include a protective layer such as the protective layer 224. The protective layer 224 may be a PI (Polyimide Film) film. Of course, the protective layer 224 may also be a film layer structure made of other materials, such as a PET (Polyethylene terephthalate) film, a PE (Polyethylene) film, etc. The first support sheet 222 is sandwiched between two protective layers 224, and the protective layer 224 covers the mesh hole 2224 to block the mesh hole 2224, so that an object (such as an adhesive such as double-sided tape, glue, etc.) provided on the first support sheet 222 will not penetrate through the mesh hole 2224 into other components. For example, the first support sheet 222 may include a first side and a second side disposed opposite to each other. The first side is the side close to the non-display surface of the flexible screen assembly 200, and the second side is the side away from the flexible screen assembly 200. A first protective layer 2241 is provided on the first side, and the first protective layer 2241 covers the mesh hole 2224 to block the mesh hole 2224 from the first side towards the second side; a second protective layer 2242 is provided on the second side, and the second protective layer 2242 covers the mesh hole 2224 to block the mesh hole 2224 from the second side towards the first side, so that an object (such as an adhesive such as double-sided tape, glue, etc.) provided on the first support sheet 222 (including the first side and the second side) will not penetrate through the mesh hole 2224 into the flexible screen assembly 200, or the middle frame, or the sliding member.

[0074] By providing the stretchable first support sheet 222 in the embodiments of the present application, not only can the tensile strength be increased, but also the risk of damage to the flexible screen assembly 200 can be reduced, and the service life of the flexible screen assembly 200 can be extended.

[0075] Please continue to refer to Figure 7, the shaft 500 can be a cylindrical structure, and a first limiting structure such as a first limiting structure is further provided on the outer surface of the shaft 500. The first limiting structure can be an annular structure provided around the outer periphery of the outer surface of the shaft 500. The number of the first limiting structures can be multiple, and the multiple first limiting structures are arranged at intervals. The number of the first limiting structures can also be one. The first limiting structure can be a protruding structure provided on the outer surface of the shaft 500 and protruding from the outer surface of the shaft 500. The first limiting structure can also be a groove structure provided on the outer surface of the shaft 500. Or when the first limiting structures are multiple, some of the first limiting structures can be protruding structures, and some of the first limiting structures can be groove structures. It should be noted that the shaft 500 can also be an irregular structure. For example, a part of the surface of the shaft 500 is an arc structure, and a part of the surface is a square structure.

[0076] The soft rubber connecting belt 221 is provided with a second limiting structure. The second limiting structure is provided on the surface of the soft rubber connecting belt 221 away from the extension part 212. The second limiting structure can be matched with the first limiting structure. For example: when the first limiting structure is a protruding structure, the second limiting structure can be a groove structure. At this time, the first limiting structure can be accommodated in the second limiting structure and connected with the second limiting structure by interference fit, so that the soft rubber connecting belt 221 moves along a preset movement track under the limiting action of the first limiting structure and the second limiting structure (for example, moves in a straight line along the direction parallel to the housing assembly 100), and further enables the extension part 212 to move to the outside or inside of the housing assembly 100 along the preset movement track. Another example: when the first limiting structure is a groove structure, the second limiting structure can be a protruding structure. At this time, the second limiting structure can be accommodated in the first limiting structure and connected with the groove wall of the first limiting structure by interference fit. Still another example: when the number of the first limiting structures is multiple, some of the first limiting structures are protruding structures, and some of the first limiting structures are groove structures, correspondingly, a plurality of second limiting structures can be provided on the outer surface of the soft rubber connecting belt 221, and some of the second limiting structures are matched with the protruding structures, and some of the second limiting structures are matched with the groove structures. It can be understood that the shapes and sizes of the first limiting structure and the second limiting structure match each other and abut against each other to limit the movement path of the soft rubber connecting belt 221.

[0077] For example, in combination with Figure 7 and Figure 18 as shown, Figure 18 is Figure 9Schematic cross-sectional structure diagram of the flexible screen assembly and the shaft along the P4-P4 direction. The first limiting structure includes a limiting groove 510, which is arranged around the outer surface of the shaft 500, and the groove width of the limiting groove 510 gradually becomes narrower from the outer surface of the shaft 500 towards the inner surface of the shaft 500. The second limiting structure may include a limiting protrusion 2211, which is arranged on the outer surface of the soft rubber connection belt 221 and protrudes from the surface of the soft rubber connection belt 221. The outer surface of the soft rubber connection belt 221 refers to the side away from the flexible screen assembly 200, and the inner surface of the soft rubber connection belt 221 refers to the side connected to the non-display surface of the flexible screen assembly 200. Among them, the material of the limiting protrusion 2211 is the same as that of the soft rubber connection belt 221, for example, both are rubber, and the width of the limiting protrusion 2211 gradually becomes wider from the inner surface of the soft rubber connection belt 221 towards the outer surface of the soft rubber connection belt 221, so that the shape of the limiting protrusion 2211 can match the shape of the limiting groove 510. The limiting protrusion 2211 can be embedded into the limiting groove 510, and the limiting protrusion 2211 can limit the movement track of the flexible screen assembly 200 through the limiting groove 510, so that the extended part 212 moves into or out of the housing assembly 100 according to a preset track. The limiting protrusion 2211 and the limiting groove 510 are connected in an interference fit. For example, the size of the limiting protrusion 2211 is slightly larger than the size of the limiting groove 510, so that when the limiting protrusion 2211 is installed in the limiting groove 510, the outer surface of the limiting protrusion 2211 is squeezed against the groove wall of the limiting groove 510 to increase the abutment firmness between the limiting groove 510 and the limiting protrusion 2211, and can also increase the friction coefficient between the shaft 500 and the soft rubber connection belt 221, forming an effective friction area between the shaft 500 and the soft rubber connection belt 221.

[0078] It can be understood that if the friction coefficient between the shaft 500 and the soft rubber connection belt 221 is too small, it may cause the soft rubber connection belt 221 to slip during the movement around the shaft 500, and then the unfolding and retracting of the extended part 212 are not smooth. In the embodiment of the present application, the limiting groove 510 and the limiting protrusion 2211 can prevent the soft rubber connection belt 221 from sliding easily, thereby ensuring the display reliability of the flexible screen assembly 200. It should be noted that the shape of the limiting groove 510 is not limited to this. For example, the limiting groove 510 can also be a dovetail groove, a square groove, etc.

[0079] In the embodiment of the present application, through the mutual cooperation of the first limiting structure and the second limiting structure, the flexible screen assembly 200 can be unfolded outside the housing assembly 100 or received inside the housing assembly 100 according to a preset movement trajectory. Compared with the related art, in the embodiment of the present application, the flexible screen assembly 200 can be prevented from shifting during the expansion process, so that the flexible screen assembly 200 is not stretched in the length direction of the electronic device 20, and further protects the flexible screen assembly 200 from damage.

[0080] Combined Figure 7 with Figure 19 as shown Figure 19 FIG. is a schematic structural diagram of the first slider and the second slider provided by the embodiment of the present application. The electronic device 20 may further include a first slider 710 and a second slider 720. For example, the first slider 710 may be disposed on the soft glue connecting belt 221 and located at the main body portion 211, and the second slider 720 may be disposed on the soft glue connecting belt 221 and located at the extended portion 212. Wherein, both the first slider 710 and the second slider 720 are slidably connected to the soft glue connecting belt 221, and both the first slider 710 and the second slider 720 are spaced apart from the shaft 500. Both the first slider 710 and the second slider 720 can slide relative to the soft glue connecting belt 221 along the surface of the soft glue connecting belt 221, so that the extended portion 212 is unfolded outside the housing assembly 100 or received inside the housing assembly 100 according to the preset movement trajectory.

[0081] In the initial state, the first slider 710 is located at the first position (as shown in Figure 7 ), and the second slider 720 is located at the second position of the soft glue connecting belt 221 (as shown in Figure 7 ). When the extended portion 212 moves in the direction away from the housing assembly 100, both the first slider 710 and the second slider 720 move in the direction close to the shaft 500, so that the first slider 710 is located at the third position (as shown in Figure 19 ), and the second slider 720 is located at the fourth position (as shown in Figure 19 ), so that the extended portion 212 located outside the housing assembly 100 can slide and unfold along the surface of the first slider 710, and the extended portion 212 located inside the housing assembly 100 can slide to the surface of the shaft 500 along the surface of the second slider 720. When the extended portion 212 moves in the direction toward the housing assembly 100, both the first slider 710 and the second slider 720 move in the direction away from the shaft 500, so that the extended portion 212 located outside the housing assembly 100 can slide to the surface of the shaft 500 along the surface of the first slider 710, and the extended portion 212 located inside the housing assembly 100 can slide to the inside of the housing assembly 100 along the second slider 720.

[0082] It can be understood that the first sliding member 710 can restrict the movement of the extended portion 212 that gradually winds out of the outer surface of the shaft 500 (or winds into the outer surface of the shaft 500), and the second sliding member 720 can restrict the movement of the extended portion 212 that gradually winds into the outer surface of the shaft 500 (or winds out of the outer surface of the shaft 500), thereby restricting the movement trajectory of the entire extended portion 212, so that the extended portion 212 gradually unfolds outside the housing assembly 100 according to the first preset movement trajectory (or gradually retracts into the housing assembly 100 according to the second preset movement trajectory).

[0083] As Figure 20 shown Figure 20 is Figure 9 a schematic cross-sectional structure diagram of the flexible screen assembly and the shaft along the P5-P5 direction. The first sliding member 710 and the second sliding member 720 are both provided with sliding portions such as the sliding portion 730, and the size and shape of the sliding portion 730 are adapted to the size and shape of the second limiting structure on the soft glue connecting band 221. For example, when the second limiting structure is a groove structure, the sliding portion 730 can be a convex structure; when the second limiting structure is a convex structure, the sliding portion 730 can be a groove structure.

[0084] The soft glue connecting band 221 is provided with limiting portions for limiting the sliding distances of the first sliding member 710 and the second sliding member 720. For example, the soft glue connecting band 221 is provided with a first limiting portion and a second limiting portion. The first limiting portion is located between the first sliding member 710 and the shaft 500, and the first limiting portion is used to limit the sliding distance of the first sliding member 710 to prevent the first sliding member 710 from sliding excessively and hitting the shaft 500; the second limiting portion is located between the second sliding member 720 and the shaft 500, and the second limiting portion is used to limit the sliding distance of the second sliding member 720 to prevent the second sliding member 720 from sliding excessively and hitting the shaft 500. Among them, the limiting portion can be a stop block, a limiting screw or other components that can serve as a limiting obstacle.

[0085] In some embodiments, the soft glue connecting band 221 can be provided with a plurality of telescopic stop blocks, and the plurality of telescopic stop blocks are arranged at different positions of the soft glue connecting band 221 at intervals. The electronic device 20 can control the telescopic stop blocks to protrude from the surface of the soft glue connecting band 221 or retract into the soft glue connecting band 221. The user can select the unfolding size of the extended portion 212, such as selecting to unfold 20%, unfold 50% or unfold 100%, etc. The electronic device 20 controls the corresponding telescopic stop blocks to protrude from the surface of the soft glue connecting band 221 according to the selected unfolding size of the user to block the continuous movement of the soft glue connecting band 221, thereby controlling the unfolding size of the extended portion 212. Compared with the rollable flexible screen in the related art, the embodiment of the present application allows the user to freely select the extended size of the display screen according to their own needs, which is more intelligent and user-friendly.

[0086] It should be noted that the structure of the first sliding member 710 is not limited to this. For example, when the size of the soft glue connecting belt 221 is equal to the size of the extension part 212, the main body part 211 is not provided with the soft glue connecting belt at this time. The first sliding member 710 may include a slide rail structure and a sliding structure that can slide along the slide rail structure. The first sliding member 710 can be made of a rigid material, such as acetal or metal material that is wear-resistant and has a large rigidity. The outer surface of the slide rail structure is flush with the outer surface of the soft glue connecting belt 221, and the slide rail structure is provided with protrusions or grooves having the same structure as the second limiting structure, so that the sliding structure can slide from the slide rail structure to the soft glue connecting belt 221.

[0087] It should be noted that when the first support piece 222 provided is a rigid piece having a mesh hole 2224 structure, the friction coefficient of the second protective layer 2242 is relatively small, so that the first sliding member 710 and the second sliding member 720 can directly slide along the surface of the second protective layer 2242, and the friction between the first sliding member 710 and the second sliding member 720 during the sliding process can also be reduced, thereby reducing the wear of the second protective layer 2242.

[0088] As Figure 21 and Figure 22 shown, Figure 21 is Figure 2 a schematic structural diagram of the central axis of the electronic device shown, Figure 22 is Figure 2 a schematic structural diagram of the central axis and the drive motor of the electronic device shown. The electronic device 20 may further include a drive motor 600. The drive motor 600 is connected to the shaft 500. The drive motor 600 can drive the shaft 500 to rotate, thereby driving the soft glue connecting belt 221 to move in the direction outside or inside the housing assembly 100. For example, the shaft 500 is provided with a through hole 520, and a plurality of card slots 521 are provided on the hole wall of the through hole 520. The output shaft 610 of the drive motor 600 is provided with a plurality of teeth 611. The teeth 611 can be engaged with the card slots 521 to connect the drive motor 600 and the shaft 500. The drive shaft rotates under the drive of the drive motor 600, thereby driving the shaft 500 to rotate around the drive motor 600. It can be understood that the drive motor 600 and the shaft 500 can jointly form a pulley-type motor device, and the shaft 500 rotates around the drive motor 600. Compared with setting the drive motor 600 outside the shaft 500, the embodiment of the present application can save the space occupied by the drive motor 600 in the electronic device 20. Of course, it is also possible to set the drive motor 600 outside the shaft 500 and provide a fixing member inside the shaft 500, and the drive motor 600 drives the shaft 500 to rotate around the fixing member.

[0089] When the drive motor 600 drives the shaft 500 to rotate clockwise, the soft rubber connection belt 221 is driven by the shaft 500 and moves around the outer surface of the shaft 500 towards the outside of the housing assembly 100, causing the extended portion 212 to gradually unfold outside the housing assembly 100; when the drive motor 600 drives the shaft 500 to rotate counterclockwise, the soft rubber connection belt 221 is driven by the shaft 500 and moves around the outer surface of the shaft 500 towards the inside of the housing assembly 100, causing the extended portion 212 to gradually retract into the housing assembly 100. The electronic device 20 can also control the operating time of the drive motor 600 to control the rotation time of the shaft 500, thereby controlling the movement distance of the extended portion 212, so that the size of the extended portion 212 unfolded outside the housing assembly 100 is adjustable, with higher playability and improved user experience.
