[0034] It should be pointed out that in the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] Please continue reading Figure 6 and Figure 8The third part 15 is basically in the shape of a hollow rectangle. The third part 15 is formed with a receiving space 150. The bottom of the receiving space 150 is open, and the cover 50 covers the bottom of the receiving space 150. The receiving space 150 can be used to place components such as the camera 60 and the main board 101. Of course, the receiving space 150 can also be used to stack and place other electrical components of the electronic device 100, such as the battery 102 and the sub-board 103. The sub-board 103 can be used to set electrical components such as speakers and microphones of the electronic device 100.

[0036] The third part 15 is also provided with a slide groove 153, which is used to cooperate with the first sliding part 113 and the second sliding part 133 so that the first part 11 and the second part 13 can slide relative to the third part 15. The third part 15 includes a third top plate 151, which is located below the first top plate 111 and the second top plate 131 and is basically in contact with the first top plate 111 and the second top plate 131. Specifically, the structures of the first part 11 and the second part 13 are basically the same, the thicknesses of the first top plate 111 and the second top plate 131 are also the same, and the upper surface of the third top plate 151 is basically in contact with the lower surface of the first top plate 111 and the lower surface of the second top plate 131. It should be noted that the fit referred to here can be understood as the contact between the two but does not affect the sliding between the two, or it can be understood as the gap between the two is within the assembly error range.

[0037] See also Figure 1 and Figure 3In this embodiment, the first part 11 forms a first sliding part 113, and the second part 13 forms a second sliding part 133, and the two sliding parts are inserted into the sliding groove 153 of the third part 15 for cooperation. In this case, the first part 11 and the second part 13 are partially received in the third part 15. It can be understood that in other embodiments, the first part 11 and the second part 13 can form sliding grooves respectively, and the third part can form two sliding parts, and the two sliding parts can be inserted into the sliding grooves of the first part 11 and the second part 13 respectively. In this case, the third part 15 is partially received in the first part 11 and the second part 13. In addition, in some embodiments, the third part 15 can also be formed with sliding grooves and sliding parts, the first part 11 forms a sliding part and is inserted into the sliding groove of the third part 15, the second part also forms a sliding groove, and the sliding part on the third part 15 is inserted into the sliding groove of the second part. In this case, the first part 11 is partially received in the third part 15, and the third part 15 is partially received in the second part 13. Of course, it is understandable that, by reasonably setting the slide groove and the sliding part, in some embodiments, the second part 13 may be partially received in the third part 15, and the third part 15 may be partially received in the first part 11. In addition, it is also understandable that, in some embodiments, the first part 11 and the second part 13 may also be completely received in the third part 15, which is not specifically limited here.

[0038] It should be pointed out that, in the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0039] In this embodiment, the first part 11 can slide relative to the third part 15 to move away from or approach one side of the third part 15, and the second part 13 can also slide relative to the third part 15 to move away from or approach the other side of the third part 15. Figure 8In the present embodiment, "the first part 11 and the third part 15 move away from each other" can be understood as the first part 11 moves away from one side of the third part 15 and the sliding direction is away from the third part 15. At this time, the second part 13 can also move away from the other side of the third part 15 and the sliding direction is away from the third part 15 or it is stationary relative to the third part 15. "The second part 13 and the third part 15 move away from each other" can be understood as the second part 13 moves away from one side of the third part 15 and the sliding direction is away from the third part 15. At this time, the first part 11 can also move away from the other side of the third part 15 and the sliding direction is away from the third part 15 or it is stationary relative to the third part 15. In other words, in the present application, the first part 11 and the second part 13 can both move away from each other individually or simultaneously relative to the third part 15, thereby expanding the display part of the display screen assembly 30. In the present embodiment, the first part 11 and the second part 13 move away from each other simultaneously relative to the third part 15 as an example for explanation. For example, from Figure 5 and Figure 6 The state shown moves to Figure 7 and Figure 8 Status shown.

[0040] In addition, in this embodiment, the first part 11 and the second part 13 can also move toward each other relative to the third part 15. In this case, it can be understood that the first part 11 and the second part 13 are respectively close to the two sides of the third part 15 and the sliding direction is toward the third part 15. Figure 7 and Figure 8 The state shown moves to Figure 5 and Figure 6 status.

[0041] It should also be pointed out that in the description of this application, it should be explained that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] Please refer to 17. In this embodiment, when the first part 11 and the second part 13 move toward each other to the extreme position relative to the third part 15 (i.e., the first part 11 and the second part 13 are close to the third part 15 until the three are matched together), the first part 11, the second part 13 and the third part 15 form a substantially rectangular shell 10 as a whole, and the first part 11 and the second part 13 are partially received inside the third part 15. Please refer to 19. When the first part 11 and the second part 13 move away from each other (i.e., they move away from each other), the first part 11 and the third part 15 move away from each other, and the second part 13 and the third part 15 move away from each other. In this case, the first part 11 and the second part 13 are still partially received in the third part 15 to be stably connected to the third part 15.

[0043] See also Figure 6 and Figure 8 In this embodiment, the reel 20 includes a first reel 21 and a second reel 23. The first reel 21 is rotatably disposed in the first portion 11 and is located in the first receiving space 110, that is, the first reel 21 can be installed in the first receiving space 110 and can rotate relative to the first portion 11. The first reel 21 is connected to one end of the flexible display assembly 30 for rolling up or releasing the flexible display assembly 30.

[0044] The second reel 23 and the first reel 21 have substantially the same structure, and the second reel 23 and the first reel 21 are symmetrically arranged about the center of the housing 10, and the second reel 23 is rotatably arranged in the second portion 13 and is located in the second receiving space 130, that is, the second reel 23 can be installed in the second receiving space 130 and can rotate relative to the second portion 13. The second reel 23 is connected to the other end of the flexible display assembly 30 for rolling up or releasing the flexible display assembly 30, that is, the first reel 21 and the second reel 23 are respectively connected to the two ends of the flexible display assembly 30.

[0045] It can be understood that the first reel 21 is rotatably disposed on the first portion 11, which may mean that the first reel 21 is directly mounted on the first portion 11, or that the first reel 21 is mounted on the first portion 11 through other media. The second reel 23 is rotatably disposed on the second portion 13, which may mean that the second reel 23 is directly mounted on the second portion 13, or that the second reel 23 is mounted on the second portion 13 through other media.

[0046] Please continue reading Figure 6 and Figure 8, the two ends of the flexible display assembly 30 are respectively wound on the first reel 21 and the second reel 23. Specifically, one end of the flexible display assembly 30 passes through the first opening 1111 of the first part 11 and is wound on the first reel 21, and the other end passes through the second opening 1311 of the second part 13 and is wound on the second reel 23. When the first part 11 and the second part 13 move away from each other, that is, when the first part 11 and the second part 13 are both away from the third part 15, the first reel 21 and the second reel 23 can rotate simultaneously to gradually release the flexible display assembly 30, thereby expanding the display part 301 of the flexible display assembly 30. The flexible display assembly 30 is also symmetrically arranged about the center of the housing 10, that is, the part of the flexible display assembly 30 wound on the first reel 21 and the part of the flexible display assembly 30 wound on the second reel 23 are symmetrical.

[0047] In this way, when the first part 11 and the second part 13 move away from each other, the first scroll 21 and the second scroll 23 can rotate to release the flexible display screen assembly 30, thereby expanding the display part 301 of the flexible display screen assembly 30. In this way, the size of the screen display area of ​​the electronic device 100 can be freely adjusted. When a large screen is needed, the display part 301 of the flexible display screen assembly 30 can be expanded to improve the user's operating experience. At the same time, when a large screen is not needed, the display part 301 can be not expanded, so that the size of the whole device is small and convenient to carry. At the same time, two scrolls are provided to retract and release the two ends of the flexible display screen assembly 30 respectively, so that the force on the two ends of the flexible display screen assembly during the rotation of the scrolls is smaller, and the unfolding process is smoother.

[0048] It can be understood that in this embodiment, in one case, the first part 11, the second part 13 and the third part 15 are close to and fully matched. In this case, the display part 301 of the flexible display assembly 30 is not expanded, and the electronic device 100 is in a narrow screen mode (for example, Figure 5 and Figure 6 At this time, one end of the flexible display screen assembly 30 is wound around the first reel 21, and the other end is wound around the second reel 23, and the portion exposed from the housing 10 (ie, the display portion 301) is used for display.

[0049] When the display portion 301 of the flexible display assembly 30 needs to be expanded, the first portion 11 and the second portion 13 move away from each other, so that the first portion 11 and the second portion 13 move away from each other, and the first scroll 21 and the second scroll 23 also move away from each other. Since the two ends of the flexible display assembly 30 are respectively connected to the first scroll 21 and the second scroll 23, during the process of moving away, the first scroll 21 and the second scroll 23 will rotate simultaneously to release the two ends of the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. In this case, the electronic device 100 is in an expansion mode (for example, Figure 7 and Figure 8 status shown).

[0050] It can be understood that there is an extreme position when the second part 13 and the first part 11 move away from each other, that is, the extreme position where the second part 13 and the first part 11 are far away from each other relative to the third part 15. When they are at the extreme position, the display area of ​​the electronic device 100 is the largest, that is, the display part 301 of the flexible display assembly 30 is the largest (see FIG. Figure 3 ). When the first part 11, the second part 13 and the third part 15 are close to and completely matched together, the display area of ​​the electronic device 100 is the smallest, that is, the display part 301 of the flexible display screen assembly 30 is the smallest (see Figure 1 ).

[0051] It should be noted that, in this embodiment, the "display portion 301 of the flexible display assembly 30" can also be understood as the portion exposed from the housing 10, that is, Figure 6 and Figure 8 The part outlined by the dotted line.

[0052] Specifically, see Figure 6 and Figure 8 In this embodiment, the flexible display screen assembly 30 includes a flexible display screen 31 and a flexible support member 33, and the flexible display screen 31 and the flexible support member 33 are stacked and fixedly connected.

[0053] The flexible display screen 31 includes a first area 311 and a second area 313 and a third area 315 connected at both ends of the first area 311. The first area 311 is located above the first top plate 111 and the second top plate 131, and its size is substantially the same as the area of ​​the first top plate 111 and the second top plate 131. The second area 313 is at least partially located in the first receiving space 110 of the first part 11 and is connected to the flexible support member 33.

[0054] The third area 315 is at least partially located in the second receiving space 130 of the second portion 13 and is connected to the flexible support member 33. In this embodiment, expanding the display portion 301 of the flexible display screen assembly 30 can be understood as pulling out the second area 313 located in the first receiving space 110 or the third area 315 located in the second receiving space 130, or pulling out both at the same time to expose from above the housing 10, thereby expanding the display portion 301 of the flexible display screen assembly 30 for display, that is, expanding the display area of ​​the electronic device 100.

[0055] The flexible support member 33 is disposed at the bottom of the flexible display screen 31 and covers the lower surface of the flexible display screen 31. The flexible support member 33 can be fixedly connected to the flexible display screen 31 by optically clear adhesive (OCA). Figure 6 and Figure 8 In the example shown, the flexible support member 33 includes a first support portion 332, a second support portion 333 and a third support portion 334, the second support portion 333 and the third support portion 334 are respectively connected to the two ends of the first support portion 332, the first support portion 332 corresponds to the flexible display screen 31, the second support portion 333 is wound on the first scroll 21, and the third support portion 334 is wound on the second scroll 23, that is, both ends of the flexible support member 34 extend beyond the flexible display screen 31, and the exceeding parts are respectively connected to the first scroll 21 and the second scroll 23.

[0056] See also Figure 6 When the electronic device 100 is in the narrow screen mode, the two ends of the flexible support member 33 are respectively connected to the first reel 21 and the second reel 23 and are respectively wound on the first reel 21 and the second reel 23. The flexible display screen 31 is roughly in the shape of a runway, and the main board 101, the sub-board, the sensor, the battery and other electrical components of the electronic device 100 can be stored in the space surrounded by the flexible display screen assembly 30. In this way, the arrangement of the flexible display screen assembly 30 will not affect the placement of the main board 101 and the battery and other electrical components, effectively improving the utilization of the space, and facilitating the stacking and placement of the main board 101, the battery and other electrical components.

[0057] In addition, when the electronic device 100 is in the narrow screen mode, the first scroll 21 and the second scroll 23 only reel in the second support portion 333 and the third support portion 334 of the flexible support member 33, and the flexible display screen 31 is not directly reeled in by the first scroll 21 and the second scroll 23, thus improving the service life of the flexible display screen 31. Of course, it can be understood that in other embodiments, the flexible display screen 31 can also be connected to the first scroll 21 and the second scroll 23 respectively after being completely corresponding to the flexible support member 33, that is, the flexible support member 33 corresponds to the flexible display screen 31, and the flexible support member 33 and the flexible display screen 31 are wound together on the first scroll 21 and the second scroll 23.

[0058] See also Figure 6 and Figure 8 In this embodiment, when the first part 11 moves away from the third part 15, the flexible support member 33 abuts against the first part 11 to keep the flexible display screen 31 flat. When the second part 13 moves away from the third part 15, the flexible support member 33 abuts against the second part 13 to keep the flexible display screen 31 flat.

[0059] In this way, the flexible support member 33 can increase the strength of the flexible display screen 31, and can ensure that the flexible display screen 31 can be flat and stable during movement, while also preventing the flexible display screen 31 from being damaged under the action of a large force.

[0060] Specifically, in this embodiment, when the first portion 11 and the third portion 15 are separated, a portion of the flexible support member 33 is attached to the first top plate 111 of the first portion 11 to fill the gap between the flexible display screen 31 and the first top plate 111 and the flexible display screen 31. When the second portion 13 and the third portion 15 are separated, a portion of the flexible support member 33 is attached to the second portion 13 and the second top plate 131 to fill the gap between the flexible display screen 31 and the second top plate 131.

[0061] Also, please read Figure 5 , Figure 6 and Figure 8 , a first tooth portion 331 is formed at the bottom of the flexible support member 33. Specifically, in the illustrated embodiment, the first support portion 332, the second support portion 333 and the third support portion 334 are all formed with the first tooth portion 331, and the first tooth portion 331 is used to engage with the stopper 40 so that the stopper 40 can support the flexible display assembly 30 and keep the flexible display assembly 30 moving smoothly. It can be understood that in other embodiments, the first support portion 332 may not have the first tooth portion 331, and the second support portion 333 and the third support portion 334 may be provided with the first tooth portion 331.

[0062] Please refer again Figure 6 and Figure 8 The limiting member 40 includes a first limiting member 41 and a second limiting member 43. The first limiting member 41 is rotatably disposed in the first portion 11 and is located in the first receiving space 110. The first limiting member 41 is cylindrical, and a second tooth portion 411 is formed on the circumference of the first limiting member 41.

[0063] The second limiting member 43 is rotatably disposed in the second portion 13 and is located in the second receiving space 130 and is symmetrical to the first limiting member 41 . The second limiting member 43 is also cylindrical, and a third tooth portion 431 is formed on the circumference of the second limiting member 43 .

[0064] The second tooth portion 411 and the third tooth portion 431 are both used to engage with the first tooth portion 331 on the flexible support member 33 to support the flexible display screen assembly 30 and guide the expansion of the flexible display screen assembly 30 .

[0065] In this embodiment, the middle part of the flexible display assembly 30 is wound around the stopper 40, that is, the middle part of the flexible display assembly 30 is wound around the first stopper 41 and the second stopper 43, and the first stopper 41 and the second stopper 43 are used to limit the shape of the flexible display assembly 30. It can be understood that the middle part of the flexible display assembly 30 can be understood as a portion located between the two ends of the flexible display assembly 30.

[0066] In this way, the first stopper 41 and the second stopper 43 can limit the shape of the flexible display assembly 30, so that the display portion 301 of the flexible display assembly 30 can be in a flat state, that is, the flexible display assembly 30 can be kept in a runway-shaped state. In addition, the first stopper 41 and the second stopper 43 are engaged with the flexible support member 33 to support the flexible display assembly 30, and to guide the first reel 21 and the second reel 23 when releasing the flexible display assembly 30 to keep the flexible display assembly 30 able to be smoothly unfolded.

[0067] Specifically, in this embodiment, the first stopper 41 is a guide gear, the first stopper 41 is arranged at a position corresponding to the first opening 1111, one end of the flexible support member 33 is wound around the second stopper 43, and the first tooth portion 331 and the second tooth portion 411 on the flexible support member 33 are meshed. The second stopper 43 can also be two guide gears, the second stopper 43 is arranged at a position corresponding to the second opening 1311, the other end of the flexible support member 33 is wound around the second stopper 43, and the first tooth portion 331 and the third tooth portion 431 on the flexible support member 33 are meshed. That is to say, one end of the flexible display screen assembly 30 passes through the first opening 1111 and bypasses the first stopper 41 to connect with the first reel 21, and the other end of the flexible display screen assembly 30 passes through the second opening 1311 and bypasses the second stopper 43 to connect with the second reel 23. When the first portion 11 and the second portion 13 move away from each other, the first stopper 41 and the second stopper 43 gradually rotate under the drive of the flexible support member 33, and the first scroll 21 and the second scroll 23 gradually release the flexible support member 33 so that more parts of the flexible display screen 31 are exposed from the housing 10 to achieve the purpose of expanding the display portion 301. In addition, please refer to Figure 6 In this embodiment, the structures of the first limiting member 41 and the second limiting member 43 are substantially the same.

[0068] It is understandable that in other embodiments, the first limit member 41 and the second limit member 43 may not be formed with teeth, but the first limit member 41 includes a first rotating shaft, the second limit member 43 includes a second rotating shaft, and the flexible support member 33 may not form the first tooth portion 331. The first limit member 41 and the flexible support member 33 are directly connected by rolling friction, and the middle part of the flexible display screen assembly 30 is arranged around the first rotating shaft and the second rotating shaft. When the first part 11 moves away from the third part 15, the flexible display screen assembly 30 drives the first rotating shaft to rotate through the friction resistance between the first rotating shaft and the second rotating shaft. When the second part 13 moves away from the third part 15, the flexible display screen assembly 30 drives the second rotating shaft to rotate through the friction resistance between the second rotating shaft. In this way, the first limit member 41 and the second limit member 43 can also support and guide the flexible display screen 32.

[0069] See also Figure 6 and Figure 8 In this embodiment, the camera 60 is disposed in the accommodation space 150 of the third portion 15, and the cover 50 is disposed on the bottom of the third portion 15 to close the accommodation space 150. That is, in this embodiment, when the second portion 13 moves relative to the first portion 11, the camera 60 does not move with it, and when the electronic device 100 is in the extended mode, the camera 60 is located in the middle of the entire flexible display screen 31.

[0070] The cover 50 is detachably connected to the first part 11 , so that the cover 50 can be easily removed to repair and replace electrical components such as the mainboard 101 , batteries or sensors stacked in the accommodating space 150 .

[0071] In addition, a light-transmitting portion 56 corresponding to the camera 60 is provided on the cover 50, and the camera 60 shell shoots through the light-transmitting portion 56. In this way, the camera 60 can be protected without affecting the shooting effect of the camera 60, thereby preventing the camera 60 from being directly exposed outside the housing 10 and causing accidental scratches on the camera. In this case, the camera 60 can be a rear camera of the mobile phone, and the rear camera can capture images through the light-transmitting portion 56 on the cover 50. It can be understood that in some embodiments, the camera 60 can also be a front camera of the mobile phone. In this case, the camera 60 can be through a hole in the flexible display assembly 30 or a hole in the housing 10 for image capture, or it can be a pop-up or slide-out mechanism. When the front camera needs to be used, the camera 60 can be popped out or slid out of the housing 10 through a pop-up mechanism or a slide-out mechanism, which can improve the screen-to-body ratio of the electronic device 100.

[0072] See also Figure 2 , Figure 4 and Figure 6 In such an embodiment, the cover body 50 includes a first connecting portion 51, a second connecting portion 53 and a third connecting portion 55. The first connecting portion 51 is fixedly connected or detachably connected to the first part 11 and closes the first storage space 110. The second connecting portion 53 is fixedly connected or detachably connected to the second part 13 and closes the second storage space 130. The third connecting portion 55 is fixedly connected or detachably connected to the third part 15 and closes the accommodating space 150.

[0073] See also Figure 2 When the electronic device 100 is in the narrow screen mode, that is, when the first portion 11 and the second portion 13 move toward each other to the extreme position and fully cooperate with the third portion 15, the first connecting portion 51, the second connecting portion 53 and the third connecting portion 55 are spliced ​​together to form the cover 50 of the electronic device 100. For details, please refer to Figure 2 , Figure 4 and Figure 6In such an embodiment, the first connection part 51 and the second connection part 53 are symmetrical about the third connection part 55, and convex arcs are formed on both the first connection part 51 and the second connection part 53, and concave arcs matching the convex arcs are formed on both sides of the third connection part 55. When the electronic device 100 is in the narrow screen mode, the concave arcs and the convex arcs are spliced ​​together to realize the splicing of the first connection part 51 and the third connection part 55 and the second connection part 53 and the third connection part 55. It can be understood that the first connection part 51, the second connection part 53 and the third connection part 55 can also be made into other forms. For example, all three are rectangular and can be directly spliced ​​into the cover body 50. For another example, regularly arranged protrusions are formed on the symmetrical sides of the third connection part 55, and grooves corresponding to the protrusions are formed on the first connection part 51 and the second connection part 53. In this way, when the electronic device 100 is in the extended mode, the form of the housing 10 can be enriched to improve the aesthetics.

[0074] Furthermore, in such an embodiment, the first connection portion 51 , the second connection portion 53 and the third connection portion 55 may be designed to have a variety of different color effects, which can enrich the appearance of the electronic device 100 .

[0075] In this embodiment, the driving mechanism includes a first driving assembly 70 and a second driving assembly 80. The first driving assembly 70 is disposed in the first receiving space 110, and the second driving assembly 80 is disposed in the second receiving space 130. The first driving assembly 70 can be connected to the first top plate 111 and the first reel 21 and is used to drive the first portion 11 to move away from the third portion 15, and can also drive the first reel 21 to rotate to release one end of the flexible display assembly 30.

[0076] The second driving assembly 80 can be connected to the second top plate 131 and the second reel 23 and is used to drive the second portion 13 to move away from the third portion 15 , and can also drive the second reel 23 to rotate to release the other end of the flexible display assembly 30 .

[0077] Specifically, see Figure 6 and Figure 8 The first driving assembly 70 may include a motor (not shown), a first transmission structure 72 and a second transmission structure 74 , and the motor may be fixedly disposed in the first receiving space 110 of the first part 11 .

[0078] The first transmission structure 72 includes a first transmission gear 722 and a rack portion 724. The first transmission gear 722 is connected to the motor, and the rack portion 724 is fixedly connected to the first top plate 111 of the first part 11, and the rack portion 724 meshes with the first transmission gear 722. Specifically, in this embodiment, the rack portion 724 is integrally formed with the first top plate 111, that is, the rack portion 724 can be directly integrally formed on the lower surface of the first top plate 111. untie In other embodiments, the rack portion 724 may be formed separately from the first top plate 111, and then the two are fixedly connected together by welding or other methods, which is not limited here.

[0079] Please refer again Figure 6 and Figure 8 The second transmission structure 74 connects the reel 20 and the first transmission gear 722. The second transmission structure 74 includes a second transmission gear 742 and a third transmission gear 744. The second transmission gear 742 is fixed on the reel 20 and is concentrically arranged with the reel 20. The third transmission gear 744 is rotatably arranged on the first part 12, and the third transmission gear 744 connects the second transmission gear 742 and the first transmission gear 722, that is, the third transmission gear 744 is meshed with the second transmission gear 742 and the first transmission gear 722 respectively, and the first transmission gear 722 and the second transmission gear 742 are located on opposite sides of the third transmission gear 744.

[0080] In this embodiment, the motor can be used to drive the first part 11 to move relative to the third part 15 through the first transmission structure 72. At the same time, the motor can also be used to drive the first scroll 21 to rotate through the second transmission structure 74 to release the flexible display assembly 30 while driving the first part 11 to move away from the third part 15.

[0081] Specifically, when it is necessary to expand the display area of ​​the electronic device 100, that is, to expand the display part 301 of the flexible display screen assembly 30, the first transmission gear 722 can be driven to rotate by a motor, and the first transmission gear 722 drives the first part 11 to move away from the third part 15 through the rack part 724. At this time, the first scroll 21 also follows the first part 11 to move relative to the third part 15. At the same time, the first transmission gear 722 can also simultaneously drive the third transmission gear 744 to rotate, and the third transmission gear 744 drives the second transmission gear 742 to rotate, and then drives the first scroll 21 to rotate, so that the scroll 20 can synchronously release the flexible display screen assembly 30, thereby achieving the purpose of expanding the display part 301 of the flexible display screen assembly 30.

[0082] It can be understood that in this embodiment, the specific structure of the second drive component 80 is the same as the specific structure of the first drive component 70, and the specific connection method between the second drive component 80 and the second part 13 is also basically consistent with the specific connection method between the first drive component 70 and the first part 11. In order to avoid redundancy, it will not be elaborated here.

[0083] In addition, when the display portion 301 of the flexible display needs to be reduced, the motor of the first driving assembly 70 only needs to be reversed to drive the first portion 11 to move relative to the third portion 15. In this case, the first scroll 21 will also be driven by the driving mechanism to reverse to gradually roll up one end of the flexible display assembly 30 (for example, from Figure 8 The state shown moves to Figure 6 status shown).

[0084] It can be understood that in this embodiment, within a unit time, the movement stroke of the first part 11 is equal to the length of the flexible display assembly 30 released by the rotation of the first scroll 21. In other words, the first scroll 21 rotates to release the same length as the movement distance of the first part 11, so that the flexible display assembly 30 can be ensured to move smoothly without wrinkles.

[0085] Similarly, when it is necessary to expand the display area of ​​the electronic device 100, the second driving component 80 arranged in the second storage space 130 can also drive the second part 13 to move away from the third part 15 and the first part 11. At the same time, the second driving component 80 also drives the second scroll 23 to rotate, so that the second scroll 23 can gradually release the flexible display screen assembly 30, thereby achieving the purpose of expanding the display part 301 of the flexible display screen assembly 30.

[0086] It is understandable that, in the present embodiment, when it is necessary to expand the display portion 301 of the flexible display assembly 30, one of the first drive assembly 70 and the second drive assembly 80 can be used alone to drive the first portion 11 or the second portion 13 to move away from the third portion 15, thereby achieving the purpose of expanding the flexible display assembly 30. Of course, the first drive assembly 70 and the second drive assembly 80 can also be used to simultaneously drive the first portion 11 and the second portion 13 to move away from the third portion 15 to achieve the same purpose. Preferably, in the present embodiment, two drive mechanisms are mainly used to synchronously drive the first portion 11 and the second portion 13 to move relative to the third portion 15 to achieve the expansion of the display portion 301 of the flexible display assembly 30. (For example, from Figure 6 The state shown moves to Figure 8 Status shown)

[0087] Next, the working principle of the electronic device 100 of this embodiment is introduced by simultaneously driving the first part 11 and the second part 13 to move by two driving mechanisms.

[0088] See also Figures 5 to 8 As described above, the electronic device 100 can switch between the narrow screen mode and the extended mode. Figure 5 and Figure 6 In the state shown, the electronic device 100 is in the narrow screen mode. Figure 7 and Figure 8 In the state shown, the electronic device 100 is in the extended mode. In the narrow screen mode, the first part 11, the second part 13 and the third part 15 cooperate with each other to form the housing 10, one end of the flexible display assembly 30 is rolled up on the first reel 21, and the other end is rolled up on the second reel 23. At this time, only a small part of the flexible display assembly 30 is exposed from the housing 10, and the display part 301 is narrow, which is convenient for users to carry.

[0089] When the user needs a larger display part 301, the first drive assembly 70 and the second drive assembly 80 respectively drive the first part 11 and the second part 13 to move away from each other relative to the third part 15, and the movement directions of the first part 11 and the second part 13 are opposite. At this time, the first drive assembly 70 and the second drive assembly 80 will also drive the first scroll 21 and the second rotating shaft 23 to rotate respectively to release the flexible display assembly 30, so that the second area 313 of the flexible display 31 hidden in the first storage space 110 will be gradually pulled out. Similarly, the third area 315 of the flexible display 31 hidden in the second storage space 130 will be gradually pulled out. In this way, the area of ​​the flexible display assembly 30 exposed from the housing 10 is large, thereby achieving the purpose of expanding the display part 301 of the flexible display assembly 30. At this time, the area of ​​the display part 301 is large, which can facilitate user operation to improve the user's operating experience.

[0090] When it is necessary to switch from the extended mode to the narrow screen mode, the motor only needs to be reversed to drive the first part 11 and the second part 13 to move toward each other relative to the third part 15. At this time, the scroll 20 also reverses accordingly to synchronously retract the flexible display assembly 30. When the first part 11, the second part 13 and the third part 15 move to the extreme position of the relative movement between them, that is, when the three are fully matched together, the motor stops running and the electronic device 100 returns to the narrow screen state.

[0091] In addition, in some embodiments, the electronic device 100 may further include an acceleration sensor (not shown), which is used to detect the motion state of the electronic device 100 .

[0092] Specifically, the acceleration sensor may be provided on the mainboard 101, and the acceleration sensor is used to detect the acceleration of the electronic device 100 within a unit time or a preset time, thereby detecting the acceleration of the electronic device 100. The mainboard 101 may determine the motion state of the electronic device 100 according to the detection data of the acceleration sensor, for example, when the detection value of the acceleration sensor exceeds a preset threshold value, it is determined that the electronic device 100 is in a falling state. In this case, the mainboard 101 may control the first driving component 70 and the second driving component 80 to drive the first part 11 and the second part 13 to move toward each other quickly relative to the third part to quickly retract the display part 301 of the flexible display screen component 30, thereby increasing the protection of the flexible display screen component 30.

[0093] In summary, the electronic device 100 of the embodiment of the present application includes a housing 10, a reel 20 and a flexible display assembly 30. The housing 10 includes a first portion 11, a second portion 13 and a third portion 15, wherein the first portion 11 and the second portion 13 are both connected to the third portion 15 and can move away from the third portion 15. The reel 20 includes a first reel 21 and a second reel 23, wherein the first reel 21 is rotatably disposed on the first portion 11, and the second reel 23 is rotatably disposed on the second portion 13. One end of the flexible display assembly 30 is wound around the first reel 21, and the other end is wound around the second reel 23. When the first portion 11 moves away from the third portion 15, the first reel 21 can rotate to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30, and when the second portion 13 moves away from the third portion 15, the second reel 23 can rotate to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30.

[0094] It can be understood that in this embodiment, in order to achieve the expansion of the display part 301 of the flexible display screen assembly 30, the following situations may be included: 1) The first part 11 moves away from the third part 15, the second part 13 is stationary relative to the third part 15, and the first scroll 21 rotates to release the flexible display screen assembly 30. 2) The second part 13 moves away from the third part 15, the first part 11 is stationary relative to the third part 15, and the second scroll 23 rotates to release the flexible display screen assembly 30. 3) Both the first part 11 and the second part 13 move away from each other relative to the third part 15, and the first scroll 21 and the second scroll 23 rotate to release the flexible display screen assembly 30.

[0095] In summary, in the electronic device 100 of the embodiment of the present application, when the first part 11 of the housing 10 moves away from the third part 15, the first scroll 21 can rotate to release the flexible display screen assembly 30, thereby expanding the display part 301 of the flexible display screen assembly 30. When the second part 13 moves away from the third part 15, the second scroll 23 can rotate to release the flexible display screen assembly 30, thereby expanding the display part 301 of the flexible display screen assembly 30. In this way, the size of the screen display area of ​​the electronic device 100 can be freely adjusted. When a large screen is needed, the display part 301 of the flexible display screen assembly 30 can be expanded to improve the user's operating experience. At the same time, when a large screen is not needed, the display part can be not expanded, so that the size of the whole machine is small and convenient to carry. At the same time, two scrolls are provided to retract and release the two ends of the flexible display screen assembly 30 respectively, so that the force on the two ends of the flexible display screen assembly 30 during the rotation of the scroll can be smaller, and the unfolding process is smoother.
