[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0035] See also Figure 1 , Figure 1 This is a schematic diagram of the first structure of an electronic device provided in an embodiment of the present application. Figure 1The electronic device 20 may be a computing device such as a laptop computer, a computer monitor containing 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 devices worn on the user's head, or other wearable or miniature devices), a television, a computer display that does not contain 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 an information kiosk or a car), a device that implements the functionality of two or more of these devices, or other electronic device. Figure 1 In the exemplary configuration of FIG, 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 electronic device 20 if desired. Figure 1 The examples are illustrative only.

[0036] like Figure 1 As shown, the electronic device 20 may include a first shell such as a first shell 100 and a second shell such as a second shell 200, and the first shell 100 and the second shell 200 are movably connected so that the distance between the first shell 100 and the second shell 200 is adjustable. The first shell 100 and the second shell 200 may be formed of plastic, glass, ceramic, fiber composite material, metal (for example, stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The first shell 100 and the second shell 200 may be formed using an integral configuration, in which some or all of the first shell 100 and the second shell 200 are processed or molded into a single structure, or may be formed using multiple structures (for example, an inner frame structure, one or more structures forming an outer shell surface, etc.). The structures and manufacturing materials of the first shell 100 and the second shell 200 may be the same or different.

[0037] See also Figure 2 , Figure 2 for Figure 1Schematic diagram of the structure of the first housing of an electronic device. The first housing 100 may include a carrier plate, such as carrier plate 110, a first side 120, and a first back cover, such as first back cover 130. The first side 120 is disposed at the periphery of the carrier plate 110. The carrier plate 110 may be used to support internal components of the electronic device 20, such as a flexible screen assembly, a drive device, a circuit board, etc. The first side 120 may be used to form a frame of the electronic device 20 to protect the internal components of the electronic device 20. The carrier plate 110, the first side 120, and the first back cover 130 are connected to form a storage cavity 140 with an opening structure to accommodate components of the electronic device 20, such as a battery and a drive device. The opening structure provides a passage for the second housing 200 to enter and exit the storage cavity 140. The second housing 200 can be moved out of the storage cavity 140 through the opening structure, and the second housing 200 can also be moved into the storage cavity 140 through the opening structure, so that the second housing 200 can be stored in the storage cavity 140.

[0038] The carrier plate 110 includes a main body portion, such as a main body portion 112, and a plurality of side portions, wherein the plurality of side portions are located at the edges of the main body portion 112. The main body portion 112 may be a regular shape, such as a rectangular structure. The carrier plate 110 may include a first side portion 114 and a second side portion 116, wherein the first side portion 114 and the second side portion 116 are disposed opposite each other.

[0039] One end of the first side 120 is connected to the first side portion 114, and the other end of the first side 120 is connected to the second side portion 116. The first side 120 is disposed between the first side portion 114 and the second side portion 116, and the two ends of the first side 120 are bent along the first side portion 114 and the second side portion 116, respectively. For example, the first side 120 has a first end and a second end opposite each other, the first end being bent in a direction parallel to the first side portion 114 and covering the outer surface of the first side portion 114, and the second end being bent in a direction parallel to the second side portion 116 and covering the outer surface of the second side portion 116. It should be noted that the two ends of the first side 240 may also be flush with the outer surfaces of the first side portion 114 and the second side portion 116.

[0040] The first back cover 130 is sleeved on the outside of the carrier plate 110 to shield the internal components disposed on the carrier plate 110, so that the user cannot observe the components disposed inside the electronic device 20 from the outside of the electronic device 20. It is understood that the flexible screen assembly, such as a portion of the flexible screen assembly 300, and the first back cover 130 are respectively disposed on two opposite sides of the carrier plate 110, and a portion of the flexible screen assembly 300 can be disposed on the display surface of the carrier plate 110 to display an image.

[0041] The flexible screen assembly 300 may include a flexible display module and a flexible support member, wherein the flexible support member is located on the non-display side of the flexible display module and is used to support the flexible display module. It is understandable that the structural strength of the flexible support member is relatively high. On the one hand, it can support the flexible display module and improve the flatness of the flexible display module, so that the flexible display module is not easy to collapse or wrinkle during the display process. On the other hand, the flexible support member can also improve the overall strength of the flexible screen assembly 300 and protect the flexible screen assembly 300 from being easily damaged during the stretching process. Among them, the flexible display module can be an OLED (Organic Light Emitting Diode) module, and the OLED module may include a display substrate and a packaging material, wherein an organic light-emitting object is packaged between the display substrate and the packaging material. The OLED module includes a number of OLED units, and each OLED unit is electrically connected to the mainboard of the electronic device to achieve self-luminescence and display images. The flexible display module can also be an LCD (Liquid Crystal Display) module. The LCD module may include a display substrate and packaging materials. Liquid crystal material is encapsulated between the display substrate and the packaging material. The motherboard of the electronic device provides voltage to the liquid crystal material, thereby changing the arrangement direction of the liquid crystal molecules. The light projected by the backlight source acts together inside the LCD module to form an image in the display area to display the picture.

[0042] The first back cover 130 may include a first bending portion 132 and a second bending portion 134 relative to each other. The first bending portion 132 is located on the outer surface of the first side portion 114 and the outer surface of the first bending portion 132 is flush with one end surface of the first side edge 120. The second bending portion 134 is located on the outer surface of the second side portion 116 and the outer surface of the second bending portion 134 is flush with the other end surface of the first side edge 120, so that the gap between the first back cover 130 and the first side edge 120 cannot be observed from the outside, which not only has the effect of waterproofing and dustproofing, but also can maintain the consistency of appearance.

[0043] like Figure 3 As shown, Figure 3 for Figure 1The schematic diagram of the structure of the second housing of the electronic device is shown. The second housing 200 may include a second side, such as the second side 210, a third side, such as the third side 220, and a fourth side, such as the fourth side 230. The second side 210 is arranged opposite the first side 120, and the second side 210 is arranged between the third side 220 and the fourth side 230. The two ends of the second side 210 are bent along the third side 220 and the fourth side 230, respectively. For example, the second side 210 has a third end, such as the third end 212, and a fourth end, such as the fourth end 214. The third end 212 is bent in a direction parallel to the third side 220 and covers the outer surface of the third side 220, and the fourth end 214 is bent in a direction parallel to the fourth side 230 and covers the outer surface of the fourth side 230. It should be noted that the end surfaces of the second side 210 may also be flush with the outer surfaces of the third side 220 and the fourth side 230.

[0044] When the second housing 200 is accommodated in the receiving cavity 140, the first end 212 of the second side 210 abuts the first bent portion 132 of the first back cover 130, and the fourth end 214 of the second side 210 abuts the second bent portion 134 of the first back cover 130, so that the first side 120, the second side 210, the third side 220, and the fourth side 230 form a complete frame structure to protect the components inside the electronic device 20 from damage. In some embodiments, the outer surface of the second side 210 is flush with the outer surface of the first end 242, and the outer surface of the third side 220 is flush with the outer surface of the second end 244, so that no gaps between the first side 120 and the second and third sides 210, 220 are visible from the outside of the electronic device 20, maintaining the consistency of the appearance of the electronic device 20.

[0045] The third side 220 and the fourth side 230 are arranged opposite to each other, and the third side 220 is movably connected to the first side 114, so that the third side 220 can move along a direction parallel to the first side 114; the fourth side 230 is movably connected to the second side 116, so that the fourth side 230 can move along a direction parallel to the second side 116, thereby allowing the second shell 200 to move to the outside of the storage cavity 140, or move to the inside of the storage cavity 140.

[0046] The second housing 200 further includes a roller, such as roller 250, disposed between the third side 220 and the fourth side 230. The flexible screen assembly 300 is disposed around the roller 250 and is movably connected to the roller 250, such that the roller 250 can rotate in accordance with the movement of the flexible screen assembly 300. The roller 250 includes a rotating shaft, such as a roller 252, and one or more rollers, such as a second roller 254 and a third roller 256. One end of the roller 252 is connected to the third side 220, and the other end of the roller 252 is connected to the fourth side 230. The second roller 254 and the third roller 256 are spaced apart so that a portion of the roller 252 is exposed. The second roller 254 and the third roller 256 are rotatably connected to the roller 252 (e.g., via a ball bearing connection), such that the second roller 254 and the third roller 256 can rotate about the roller 252.

[0047] Combine Figure 4 and Figure 5 As shown, Figure 4 This is a second structural diagram of an electronic device provided in an embodiment of the present application. Figure 5 This is a schematic diagram of the third structure of the electronic device provided in an embodiment of the present application. Another part of the flexible screen assembly 300 can be wrapped around the second roller 254 and the third roller 256 and slide along the outer surface of the second roller 254 and the third roller 256, which can reduce the friction between the flexible screen assembly 300 and the second roller 254 and the third roller 256, making the flexible screen assembly 300 move more smoothly. In addition, the flexible screen assembly 300 can also drive the second roller 254 and the third roller 256 to rotate during the sliding process. When the second roller 254 and the third roller 256 rotate, they can drive the second shell 200 to move, further increasing the speed at which the second shell 200 moves away from or close to the first shell 100.

[0048] It should be noted that one or more rollers may not be provided on the outside of the roller 252. For example, the flexible screen assembly 300 may be directly placed on the outer surface of the roller 252 so that the flexible screen assembly 300 can slide along the outer surface of the roller 252.

[0049] like Figure 5 As shown, the electronic device 20 may further include a first driving device such as a first driving device 400. The first driving device 400 may be arranged on the first shell 100, for example, the first driving device 400 may be arranged on the supporting plate 110, or the first driving device 400 may also be arranged on the second shell 200, for example, the first driving device 400 may be arranged on the second side 210, the third side 220 and / or the fourth side 230 of the second shell 200, or the second shell 200 may also be provided with a substrate, and the first driving device 400 may be arranged on the substrate.

[0050] The first drive device 400 is used to drive the relative movement of the first housing 100 and the second housing 200 to achieve engagement and separation of the first housing 100 and the second housing 200. For example, the first housing 100 can be stationary, and the first drive device 400 can drive the second housing 200 to move away from the first housing 100, causing the second housing 200 to extend from the receiving cavity 140 to achieve separation between the first housing 100 and the second housing 200. The first drive device 400 can also drive the second housing 200 to move toward the first housing 100, causing the second housing 200 to enter and be accommodated in the receiving cavity 140 to achieve engagement between the first housing 100 and the second housing 200. It is understood that the first housing 100 and the second housing 200 can reciprocate in a direction parallel to the first housing 100 or the second housing 200 to achieve engagement and separation between the first housing 100 and the second housing 200.

[0051] Alternatively, in the above embodiment, the second housing 200 may be fixed, and the first driving device 400 may drive the first housing 100 to reciprocate in a direction parallel to the second housing 200. Alternatively, the first driving device 400 may drive the first housing 100 and the second housing 200 to move simultaneously to achieve engagement and separation of the first housing 100 and the second housing 200.

[0052] Combine Figure 4 and Figure 5 As shown, the first driving device 400 may include a first motor such as a first motor 420 and a pushing mechanism such as a pushing mechanism 440. The pushing mechanism 440 is connected to the first motor 420. The first motor 420 is used to drive the pushing mechanism 440 to push the second shell 200 to reciprocate in a direction parallel to the first shell 100, so that the second shell 200 extends out of or enters the storage cavity 140, thereby realizing the separation or engagement between the second shell 200 and the first shell 100.

[0053] The pushing mechanism 440 may include a transmission assembly, such as a transmission assembly 442, and a push rod, such as a push rod 444. The transmission assembly 442 is connected to the first motor 420. One end of the push rod 444 is connected to the transmission assembly 442, and the other end of the push rod 444 is connected to the second housing 200. The first motor 420 is used to drive the transmission assembly 442 to move, so that the push rod 444 connected thereto moves along with the transmission assembly 442, thereby causing the push rod 444 to move in a direction parallel to the first housing 100. The transmission assembly 442 may be one or a combination of a screw transmission assembly, a gear set, or a telescopic assembly. The telescopic assembly may include an electric push rod, an electro-hydraulic push rod, a pneumatic push rod, or a hydraulic push rod.

[0054] The pushing assembly 444 may include a first base, such as first base 4441, and a push rod, such as push rod 4442. The first base 4441 is fixed to the supporting plate 110. The first base 4441 is provided with a slide groove. The push rod 4442 is disposed within the slide groove and slidably connected thereto so that the push rod 4442 can slide within the slide groove. One end of the push rod 4442 is connected to the transmission assembly 442, and the other end of the push rod 4442 is connected to the second housing 200. For example, the push rod 4442 may be connected to the roller 252.

[0055] When the electronic device 20 wants to control the relative movement of the first shell 100 and the second shell 200, the first motor 420 can be controlled to drive the transmission component 442 to move. When the transmission component 442 moves, it drives the push rod 4442 to slide in the slide groove in a direction parallel to the first shell 100, and then drives the second shell 200 to move in a direction parallel to the first shell 100, so as to realize the engagement and separation of the first shell 100 and the second shell 200.

[0056] For example, the electronic device 20 can control the output shaft of the first motor 420 to rotate in the forward direction, so that the transmission component 442 connected to the output shaft of the first motor 420 follows the movement of the output shaft of the first motor 420. During the movement of the transmission component 442, the push rod 4442 will be driven to move in the direction away from the first shell 100. The second shell 200 connected to the push rod 4442 will move along with the movement of the push rod 4442, so that the second shell 200 also moves in the direction away from the first shell 100, and then the second shell 200 extends from the storage cavity 140, thereby realizing the separation of the second shell 200 from the first shell 100. For another example: the electronic device 20 can control the output shaft of the first motor 420 to rotate in the opposite direction, so that the transmission component 442 connected to the output shaft of the first motor 420 moves along with the output shaft of the first motor 420. During the movement of the transmission component 442, the push rod 4442 will be driven to move toward the direction close to the first shell 100. The second shell 200 connected to the push rod 4442 will move along with the movement of the push rod 4442, so that the second shell 200 also moves toward the direction close to the first shell 100, thereby causing the second shell 200 to shrink from the outside of the storage cavity 140 to the inside of the storage cavity 140, thereby realizing the interlocking of the second shell 200 with the first shell 100.

[0057] The outer surface of push rod 4442 is further provided with an elastic member, such as elastic member 4443. Elastic member 4443 may be a spring or other elastic component. Elastic member 4443 may be used to support and protect push rod 4442. For example, when electronic device 20 falls, elastic member 4443 may act as a buffer, reducing the instantaneous impact force on push rod 4442, thereby reducing the impact force on transmission assembly 442 connected to push rod 4442, and protecting transmission assembly 442 from damage.

[0058] like Figure 6 As shown, Figure 6 for Figure 5 Schematic diagram of the structure of the first driving device in the electronic device shown. The transmission assembly 442 may include a second base 4421, a transmission screw 4422, and a connector 4423, wherein the second base 4421 is fixed to the first housing 100, for example, the second base 4421 can be fixed to the carrier plate 110. The transmission screw 4422 is rotatably connected to the second base 4421, for example, the transmission screw 4422 can be connected to a bearing embedded in the second base 4421, thereby enabling the transmission screw 4422 to rotate relative to the second base 4421. The transmission screw 4422 is also connected to the first motor 420, and the first motor 420 is used to drive the transmission screw 4422 to rotate relative to the second base 4421. The connecting member 4423 is sleeved on the transmission screw 4422 and is transmission-connected to the transmission screw 4422. The connecting member 4423 is also connected to the push rod 4442. Driven by the transmission screw 4422, the connecting member 4423 reciprocates along the axial direction perpendicular to the transmission screw 4422, thereby driving the push rod 4442 to reciprocate along a direction parallel to the first shell 100. When the push rod 4442 reciprocates, the second shell 200 follows the push rod 4442 to reciprocate.

[0059] Combine Figure 7 As shown, Figure 7 for Figure 6 Schematic diagram of the structure of the connecting member in the first drive device. The transmission assembly 442 may further include a guide rod such as guide rod 4424, which is disposed on the second base 4421. For example, the ends of the guide rod 4424 may be directly inserted and fixed into the connection holes of the second base 4421. The guide rod 4424 is arranged in parallel with the transmission screw 4422, and the connecting member 4423 can be simultaneously mounted on the transmission screw 4422 and the guide rod 4424. The guide rod 4424 can guide and position the connecting member 4423. For example, the connecting member 4423 may be provided with a first through-hole 4423a, a second through-hole 4423b, and a third through-hole 4423c. The connecting member 4423 is sleeved onto the transmission screw 4422 through the first through-hole 4423a, sleeved onto the push rod 4442 through the second through-hole 4423b, and sleeved onto the guide rod 4424 through the third through-hole 4423c, in sliding contact with the guide rod. A transmission thread is provided on the wall of the first through-hole 4423a, which engages with the threaded teeth of the transmission screw 4422, so that when the transmission screw 4422 rotates, it drives the connecting member 4423 through the first through-hole 4423a to perform linear motion in a direction parallel to the first housing 100. It is understood that the rotation of the transmission screw 4422 can be converted into linear motion of the connecting member 4423.

[0060] like Figure 8 and Figure 9 As shown, Figure 8 This is a fourth structural diagram of an electronic device provided in an embodiment of the present application. Figure 9 for Figure 8 Schematic diagram of the structure of the first driving device in the electronic device shown. The transmission component 442 can also be a gear set transmission. For example, the transmission component 442 includes a gear such as gear 446. The gear 446 is arranged on the output shaft of the first motor 420, and the first motor 420 can drive the gear 446 to rotate. The push rod 4442 is connected to the gear 446 through transmission. For example, a plurality of teeth can be provided on the outer surface of the push rod 4442. The push rod 4442 engages with the gear 446 through the teeth, so that when the gear 446 rotates, it can drive the push rod 4442 to reciprocate in a direction parallel to the first shell 100. It should be noted that the transmission component 442 can also include multiple gears, and the reciprocating motion of the push rod 4442 is driven by the mutual transmission of the multiple gears.

[0061] Combine Figure 4 、 Figure 6 and Figure 10 As shown, Figure 10 This is a fifth structural diagram of an electronic device provided in an embodiment of the present application. The electronic device 20 may further include a second driving device, such as a second driving device 500, which is connected to the flexible screen assembly 300. The second driving device 500 can be used to drive the flexible screen assembly 300 to follow the relative movement of the first shell 100 and the second shell 200, and to retract a portion of the flexible screen assembly 300 into the first shell 100 or to unfold a portion of the flexible screen assembly 300 outside the first shell 100 to increase the display area of ​​the electronic device 20.

[0062] For example, the flexible screen assembly 300 may include a first display portion 320 and a second display portion 340, the first display portion 320 refers to a portion of the flexible screen assembly 300 located on the first shell 100, and the second display portion 340 refers to another portion of the flexible screen assembly 300 located on the second shell 200. In the initial state, the first display portion 320 is exposed to the outside of the first shell 100 (or the outside of the electronic device 20), and the second display portion 340 is received in the receiving cavity 140, such as Figure 1 When the first driving device 400 drives the second shell 200 to move in a direction away from the first shell 100, the second driving device 500 can drive the flexible screen assembly 300 to follow the movement of the second shell 200 after a preset interval, so that the second display portion 340 originally stored in the storage cavity 140 slowly slides along the roller 250 and gradually unfolds outside the first shell 100 (or outside the electronic device 20), such as Figure 4 or Figure 5 As shown, the first display portion 320 and the second display portion 340 are both unfolded outside the electronic device 20. The first display portion 320 and the second display portion 340 can display one screen together or two screens separately. Compared with only using the first display portion 320 for display in the initial state, unfolding the second display portion 340 outside the storage cavity 140 can increase the display area of ​​the electronic device 20.

[0063] The embodiment of the present application provides two drive devices to control the motion states of the first housing 100, the second housing 200, and the flexible screen assembly 300, respectively, making the display area of ​​the flexible screen assembly 300 selectable. Compared to the display screens in the related art with fixed installation space, the embodiment of the present application can increase the display area of ​​the electronic device 20 without increasing the installation space of the flexible screen assembly 300 (or the display screen).

[0064] Please continue reading Figure 6 and Figure 10 The second driving device 500 includes a second motor, such as a second motor 520, and a connecting belt, such as a connecting belt 540. The second motor 520 is used to drive the connecting belt 540 to curl or stretch, so that the other part of the flexible screen assembly 300 is stored in the storage cavity 140 or extended outside the first shell 100. For example, one end of the connecting belt 540 is wrapped around the output shaft of the second motor 520, and the other end of the connecting belt 540 is connected to one end of the flexible screen assembly 300, and the other end of the flexible screen assembly 300 is connected to the first shell 100.

[0065] When the electronic device 20 wants to control the flexible screen assembly 300 to unfold outside the first shell 100, the electronic device 20 can control the second motor 520 to drive the connecting belt 540 to gradually change from a curled state to an extended state, so that the second display part 340 can slide along the outer surface of the second roller 254 and the outer surface of the third roller 256 in the direction away from the second motor 520, so as to gradually unfold the second display part 340 originally stored in the storage cavity 140 to the outside of the electronic device 20 (or the first shell 200), and display the picture together with the first display part 320 originally exposed outside the electronic device 20.

[0066] When the electronic device 20 wants to control the flexible screen assembly 300 to be stored in the first shell 100, the electronic device 20 can control the second motor 520 to drive the connecting belt 540 to gradually change from an extended state to a curled state, so that the flexible screen assembly 300 can slowly slide along the outer surface of the second roller 254 and the outer surface of the third roller 256 toward the direction close to the second motor 520, so as to gradually retract the second display part 340 originally unfolded outside the electronic device 20 (or the first shell 200) into the storage cavity 140 (or the first shell 100).

[0067] Among them, the size of the second display part 340 is less than or equal to the size of the first shell 100, so that the second display part 340 can be fully unfolded when stored in the storage cavity 140 without being curled. Compared with the display screen that needs to be curled in the related art, the embodiment of the present application can avoid the flexible screen component being easily damaged due to frequent curling, and can extend the service life of the flexible screen component.

[0068] When the first driving device 400 drives the first shell 100 and the second shell 200 to move relative to each other, if the second driving device 500 moves simultaneously with the first driving device 400, the flexible screen assembly 300 will become loose, which may cause the flexible screen assembly 300 to become wrinkled or uneven, thereby affecting the screen display effect of the electronic device 20.

[0069] like Figure 11 As shown, Figure 11 This is a sixth structural diagram of an electronic device provided in an embodiment of the present application. In order to keep the flexible screen assembly 300 in a taut state and ensure the tension of the flexible screen assembly 300, the processor of the electronic device 20 in an embodiment of the present application, such as the processor 600, is electrically connected to the first drive device 400 and the second drive device 500. The processor 600 can be used to drive the first drive device 400 to drive the first shell 100 and the second shell 200 to move relative to each other at different times, and the second drive device 500 to drive the flexible screen assembly 300 to move following the relative movement of the first shell 100 and the second shell 200, so that the first drive device 400 and the second drive device 500 are driven step by step and synchronously. It can be understood that there is a time difference between the driving time of the first drive device 400 and the second drive device 500. This time difference is very short and is mainly used to ensure that both ends of the flexible screen assembly 300 are always in a taut state under stress, ensure the tension of the flexible screen assembly 300, and ensure that wrinkles and unevenness do not occur, thereby ensuring that the screen display effect of the electronic device 20 is not affected by the movement of the flexible screen assembly 300.

[0070] For example, when the second display portion 340 needs to be unfolded, the processor 600 can control the first driving device 400 to drive the second shell 200 to move in a direction away from the first shell 100 at the first moment T1, so that the second shell 200 slowly extends out of the storage cavity 140 to achieve the separation of the first shell 100 and the second shell 200. When the second shell 200 moves to the second moment T2, the processor 600 controls the second motor 520 to drive the connecting belt 540 to slowly unfold, so that the second display portion 340 of the flexible screen assembly 300 can slide along the outer surface of the second roller 254 and the third roller 256 to the outside of the storage cavity 140. Among them, the first moment T1 is earlier than the second moment T2, for example, T2=T1+t1, t1 is the first preset interval time, and the first preset interval time can be set according to actual conditions, and the embodiment of the present application is not limited thereto. It can be understood that when the second display part 340 is unfolded, the second shell 200 moves before the flexible screen assembly 300, so that the flexible screen assembly 300 is always in a stretched state during the process of the second display part 340 gradually unfolding outside the first shell 100.

[0071] When the second display portion 340 needs to be retracted into the storage cavity 140, the processor 600 can control the second motor 520 at the third time T3 to drive the connecting belt 540 to slowly curl. During the curling process, the connecting belt 540 pulls the second display portion 340 toward the second motor 520. During the movement of the second display portion 340, the second roller 254 and the third roller 256 rotate, thereby causing the second side 210 to move toward the first side 120. When the flexible screen assembly 300 moves to the fourth time T4, the processor 600 controls the first driving device 400 to drive the second shell 200 in a direction away from the first shell 100, causing the second shell 200 to slowly retract into the storage cavity 140 to achieve the interlocking of the first shell 100 and the second shell 200. The third time T3 is earlier than the fourth time T4, for example, T4 = T3 + t2, where t2 is the second preset interval time. The second preset interval time can be set according to actual conditions and is not limited in this embodiment of the present application. It can be understood that when the second display part 340 is recovered, the flexible screen assembly 300 moves before the second shell 200, so that the flexible screen assembly 300 is always in a stretched state during the process of gradually recovering the second display part 340 into the first shell 100.

[0072] In some other embodiments, the processor 600 may also control the first drive device 400 and the second drive device 500 according to the tension value of the flexible screen assembly 300. For example, the flexible screen assembly 300 may be provided with a tension detector, which is used to detect the tension value of the flexible screen assembly 300. When it is necessary to unfold the second display portion 340, the processor 600 first controls the first drive device 400 to start, and obtains the first tension value of the flexible screen assembly 300 detected by the tension detector, and controls the second drive device 500 to start when the first tension value of the flexible screen assembly 300 is greater than the first preset tension value. Similarly, when it is necessary to retract the second display portion 340, the processor 600 first controls the second drive device 500 to start, and obtains the second tension value of the flexible screen assembly 300 detected by the tension detector, and controls the first drive device to start when the second tension value of the flexible screen assembly 300 is greater than the second preset tension value. The embodiment of the present application determines the activation time of the first drive device 400 and the second drive device 500 based on the tension value of the flexible screen assembly 300. This can avoid the situation where the flexible screen assembly 300 is wrinkled due to too little tension due to a too short activation time interval, and can also avoid the situation where the flexible screen assembly 300 is damaged due to too much tension due to a too long activation time interval. Compared to controlling the activation of the two drive devices based on a fixed time interval, the control of the embodiment of the present application is more accurate and intelligent.

[0073] In the above embodiment, alternatively, the electronic device 20 may be provided with only the first driving device 400 without providing the second driving device 500, such as Figure 12 As shown, Figure 12 This is a seventh structural diagram of an electronic device provided in an embodiment of the present application. One end of the flexible screen assembly 300 is connected to the first housing 100, and the other end of the flexible screen assembly 300 is connected to the first driving device 400. The first driving device 400 drives the first housing 100 and the second housing 200 to move relative to each other and drives the flexible screen assembly 300 to move, so that the second display portion 340 of the flexible screen assembly 300 extends out of the storage cavity 140 and unfolds on the outer surface of the second housing 100, so that the second display portion 340 can display the image together with the first display portion 320.

[0074] like Figure 13 and Figure 14 As shown, Figure 13 for Figure 12 The schematic structural diagram of the first driving device in the electronic device shown is as follows, Figure 14 for Figure 12Schematic diagram of the structure of the pushing component in the first driving device shown. The push rod 4442 includes a support portion 4442a, a rotating shaft 4442b and a pushing portion 4442c, one end of the pushing portion 4442 is fixed on the support portion 4442a, the other end of the pushing portion 4442c is connected to the roller 250 (for example, connected to the roller 252), and the rotating shaft 4442b is arranged at the end of the support portion 4442a away from the roller 250. The flexible screen assembly 300 is slidably connected to the rotating shaft 4442b through a connecting belt 540. For example, the connecting belt 540 is wound around the rotating shaft 4442b, and one end of the connecting belt 540 is fixedly connected to the first shell 100, and the other end of the connecting belt 540 is connected to the other end of the flexible screen assembly 300.

[0075] When the second display portion 340 needs to be unfolded, the processor 600 can control the first motor 420 to drive the transmission component 442 to move, and the transmission component 442 drives the pushing component 444 to move in a direction away from the first shell 100. During the movement, the pushing component 444 pushes the second shell 200 to move in a direction away from the first shell 100 through the pushing portion 4442c. At the same time, since the rotating shaft 4442b also moves in a direction away from the first shell 100, the connecting belt 540 also follows the rotating shaft 4442b to move in a direction away from the first shell 100 and slides along the outer surface of the rotating shaft 4442b, thereby increasing the length of the connecting belt 540 on the second shell 200. Under the joint action of the second shell 200 and the connecting belt 540, the second display portion 340 slides along the roller 250 toward the outer surface of the second shell 200 to the outside of the storage cavity 140, so that the second display portion 340 is exposed to the outside of the electronic device 20. It can be understood that when the flexible screen assembly 300 receives the thrust applied to it by the second shell 200, the connecting belt 540 gradually reduces the pulling force on the flexible screen assembly 300, so that the second display part 340 of the flexible screen assembly 300 can be unfolded.

[0076] When the second display unit 340 needs to be recovered, the processor 600 can control the first motor 420 to drive the transmission component 442 to move, and the transmission component 442 drives the pushing component 444 to move in the direction close to the first shell 100. During the movement, the pushing component 444 pulls the second shell 200 through the pushing part 4442c to move in the direction close to the first shell 100. At the same time, since the rotating shaft 4442b also moves in the direction close to the first shell 100, the connecting belt 540 also follows the rotating shaft 4442b to slide along the outer surface of the rotating shaft 4442b in the direction close to the first shell 100, thereby reducing the length of the connecting belt 540 on the second shell 200. Under the joint action of the second shell 200 and the connecting belt 540, the second display unit 340 slides along the roller 250 toward the inner surface of the second shell 200 to the storage cavity 140, so that the second display unit 340 is recovered into the storage cavity 140. It can be understood that when the second shell 200 moves toward the first shell 100, the thrust applied by the second shell 200 to the flexible screen assembly 300 will gradually decrease. At this time, when the connecting belt 540 moves toward the first shell, it will pull the flexible screen assembly 300 toward the first shell 100, so that the second display part 340 of the flexible screen assembly 300 can be recovered into the storage cavity 140.

[0077] It should be noted that when the second display part 340 of the flexible screen assembly 300 is unfolded to the outside of the first shell 100 or retracted into the first shell 100, the flexible screen assembly 300 remains in a straight state under the joint action of the second shell 200 and the connecting belt 540, ensuring that the screen display effect of the electronic device 20 is not affected.

[0078] To prevent excessive friction between the connecting belt 540 and the rotating shaft 4442b, which would cause the connecting belt 540 to exert excessive tension on the flexible screen assembly 300 and thus damage the flexible screen assembly 300 due to excessive tension, the outer surface of the rotating shaft 4442b in the present embodiment is further provided with a first roller, such as a first roller 4442d. The first roller 4442d is rotatably connected to the rotating shaft 4442b so that the first roller 4442d can rotate about the rotating shaft 4442b. This allows the connecting belt 540 to drive the first roller 4442d to rotate when it moves, thereby reducing the friction between the connecting belt 540 and the first roller 4442d, making the connecting belt 540 move more smoothly and preventing the connecting belt 540 from exerting excessive tension on the flexible screen assembly 300 and causing damage to the flexible screen assembly 300. The first roller 4442d can also form a combined rolling mechanism with the roller 250 to ensure smooth recovery and deployment of the flexible screen assembly 300. The rotation speed of the first roller 4442d is the same as that of the roller 250, so that the first roller 4442d and the roller 250 form a combined driven mechanism, thereby making the unfolded length of the second display portion 340 and the movement distance of the connecting belt 540 equal.

[0079] It can be understood that the first motor 420 in the embodiment of the present application provides an active driving effect, and the roller 250 and the rotating shaft 4442b on the second shell 200 are a combined driven mechanism, which performs linked movement under the active drive of the first motor 420, so that the movement distance of the pushing part 4442c, the unfolding length of the second display part 340 and the movement distance of the connecting belt 540 are equal, thereby ensuring that the flexible screen assembly 300 is always in a taut state during the unfolding process and the recycling process (ensuring that the tension of the flexible screen assembly 300 is within a certain range), avoiding abnormal situations such as the flexible screen assembly 300 being damaged due to excessive tension or the flexible screen assembly 300 being wrinkled due to too little tension due to asynchronous unfolding.

[0080] In the embodiment of the present application, the relative movement of the first shell 100 and the second shell 200 and the expansion and recovery of the flexible screen assembly 300 can be achieved through the first driving device 400. Compared with the above-mentioned application embodiment, one driving device can be reduced, and the structure of the electronic device 20 can be simplified based on the above-mentioned application embodiment.

[0081] like Figure 3As shown, the second housing 200 may further include a second back cover, such as a second back cover 240, which is provided on the second side 210, the third side 220, and the fourth side 230 to cover the devices provided on the second housing 200. It is understood that the second display portion 340 of the flexible screen assembly 300 is provided on one side of the second side 210, the third side 220, and the fourth side 230, and the second back cover 240 is provided on the other side of the second side 210, the third side 220, and the fourth side 230. The second display portion 340 of the flexible screen assembly 300 can display images together with the first display portion 320 provided on the first housing 100. It should be noted that the first display portion 320 provided on the first housing 100 can also display images independently.

The description of the above embodiments is intended only to facilitate understanding of the present application. Furthermore, those skilled in the art will appreciate that variations in the specific implementation methods and scope of application may occur based on the concepts of the present application.
