A first sliding structure 113 can be provided on the second surface 112, and the first sliding structure 113 cooperates with the second shell 12 to enable the first shell 11 and the second shell 12 to be slidably connected. In this embodiment, the first sliding structure 113 can be a guide groove 113a (such as Figure 5 As shown in FIG. 1 , the second housing 12 is clamped in the guide slot 113a and can move along the direction of the guide slot 113a. In other embodiments, the first sliding structure 113 can also be a guide slider 113b (as shown in FIG. 1 ).

In other embodiments, the guide limit assembly 30 is fixed to the surface of the baffle 124 away from the second shell 12 or is integrally formed with the baffle 124. The guide limit assembly 30 has a curved guide portion 310, and the second end 202 is partially attached to the guide portion 310.

The first fixed portion 211, the second fixed portion 221 and the third fixed portion 231 are respectively located at the first end 201 of the flexible screen assembly 20, and the first bending portion 212, the second bending portion 222 and the third bending portion 232 are respectively located at the second end 202 of the flexible screen assembly 20.

[0042] Please refer to Figure 3 and Figure 8 , Figure 8 yes Figure 4 A three-dimensional schematic diagram of a flexible screen layer in a flexible screen assembly in an electronic device shown. The first bending portion 212 of the flexible screen layer 21 may include a bending area 2121 and a to-be-bent area 2122.

When the electronic device returns to a normal state, the bending area 2121 can be transformed into the second bending area 2124 as the roller rotates, and the first bending area 2123 can be transformed into the bending area 2121 until the first bending area 2123 is completely transformed into the bending area 2121.

[0043] Optionally, the protective film layer 22 is a mesh steel sheet structure, which is used to protect the flexible screen layer 21 on the one hand, preventing the first surface 111 of the first shell 11 from being directly fixedly connected to the first fixing portion 211 of the flexible screen layer 21 and the first limiting portion 321 from being directly connected to the first bending portion 212 of the flexible screen layer 21, thereby scratching the flexible screen layer 21; on the other hand, it makes the second bending portion 222 of the protective film layer 22 easy to bend and can be deformed with the flexible screen layer 21 without affecting the bending performance of the flexible screen. In addition, the protective film layer 22 has a mesh structure, so that the fixed adhesive layer 23 can partially pass through the protective film layer 22 and fixedly connect the protective film layer 22 and the flexible screen layer 21.

[0044] Furthermore, the surface of the third fixed portion 231 of the fixed adhesive layer 23 facing away from the protective film layer 22 is fixedly connected to the first surface 111 of the first shell 11, so as to realize that the first end 201 of the flexible screen assembly 20 is connected to the first shell 11; the surface of the third bent portion 232 of the fixed adhesive layer 23 facing away from the protective film layer 22 is adhered to the guide portion 310 and the fourth surface 122 of the second shell 12 through the first limiting portion 321, so as to realize that the second end 202 of the flexible screen assembly 20 is connected to the second shell 12.

Fig.10 yes Fig. 9 The exploded schematic diagram of the guide member and the second limiting portion in the guide limiting assembly shown in FIG. Fig.11 yes Fig. 9 An exploded schematic diagram of a limiter in a guide limiter assembly is shown. In the first embodiment, the first limiter portion 321 of the limiter 32 may include a first magnetic structure 321a, and the second limiter portion 322 of the limiter 32 may include a second magnetic structure 322a. The first magnetic structure 321a interacts with the second magnetic structure 322a to bring the display screen layer of the flexible screen layer 21 close to the guide portion 310, that is, the first magnetic structure 321a interacts with the second magnetic structure 322a through magnetic attraction to bring the flexible screen assembly 20 close to the guide limiter assembly 30. Among them, the first limiter portion 321 may include one or more first magnetic structures 321a, and the second limiter portion 322 may include one or more second magnetic structures 322a.

[0046] Furthermore, the second limiting portion 322 includes a plurality of second magnetic structures 322a, and the plurality of second magnetic structures 322a are arranged at intervals on the guide member 31. On the one hand, it is convenient to adjust the interaction force between the second magnetic structure 322a and the first magnetic structure 321a, so that the flexible screen assembly 20 can be attached to the guide portion 310 without affecting the separation of the second magnetic structure 322a and the first magnetic structure 321a. On the other hand, the force on the flexible screen assembly 20 is uniform to avoid arching of the flexible screen assembly 20.

[0047] Furthermore, the second magnetic structure 322a is an annular body, and the second magnetic structure 322a is sleeved on the guide member 31, and the outer surface of the second magnetic structure 322a is flush with the outer surface of the guide member 31, so that the second magnetic structure 322a and the guide member 31 can support the flexible screen assembly 20 at the same time to avoid the arching phenomenon caused by uneven force on the surface of the flexible screen assembly 20.

[0048] In this embodiment, the guide member 31 may include a rotating shaft structure 311, and the curved guide portion 310 is located on the rotating shaft structure 311. The rotating shaft structure 311 is rotatably connected to the second shell 12. The second magnetic structure 322a is sleeved on the rotating shaft structure 311 and can rotate with the rotating shaft structure 311 to guide the movement of the flexible screen assembly 20 while reducing the friction between the flexible screen assembly 20 and the guide member 31, so that the movement of the flexible screen assembly 20 is smoother.

[0049] Furthermore, the guide member 31 may also include a plurality of sleeve structures 312, and the plurality of sleeve structures 312 are fixedly arranged at intervals on the rotating shaft structure 311, and each second magnetic structure 322a is fixed between two adjacent sleeve structures 312 to achieve the limiting fixation of the sleeve structure 312.

In this embodiment, the outer surface of the second magnetic structure 322a is flush with the outer surface of the sleeve structure 312, so that the outer surface of the sleeve structure 312 and the outer surface of the second magnetic structure 322a simultaneously support the flexible screen assembly 20, thereby making the flexible screen assembly 20 evenly stressed.

[0050] Optionally, the first magnetic structure 321a is strip-shaped and its length direction is parallel to the axial direction of the hinge structure 311. There are multiple first magnetic structures 321a and they are arranged side by side, so that when the flexible screen assembly 20 is bent, the first magnetic structure 321a does not affect the bending performance of the flexible screen assembly 20.

[0051] Furthermore, two adjacent first magnetic structures 321 a are spaced apart to avoid interference between the two adjacent first magnetic structures 321 a when the flexible screen assembly 20 is bent, thereby preventing the bending performance of the flexible screen assembly 20 from being affected.

[0052] Please continue to refer to Figure 7 In a variation of this embodiment, the guide member 31 is fixedly connected to the second housing 12, or the guide member 31 is integrally formed with the second housing 12. The guide portion 310 includes a curved surface 3101 away from the surface of the second housing 12, and the second limiting portion 322 is provided on the curved surface 3101. The first limiting portion 321 cooperates with the second limiting portion 322 and can slide relative to the second limiting portion 322 to support the flexible screen assembly 20 and make the flexible screen assembly 20 fit on the guide member 31.

[0053] Optionally, the first limiting portion 321 is a magnetic plate structure and its shape corresponds to the curved surface 3101, and the second limiting portion 322 is a magnetic strip, so that the second limiting portion 322 is adsorbed on the first limiting portion 321 and can slide relative to the first limiting portion 321, thereby making the flexible screen assembly 20 close to the guide member 31.

[0054] Optionally, the first limiting portion 321 is strip-shaped and the length direction is parallel to the axial direction of the rotating shaft structure 311. There are multiple first limiting portions 321 and they are arranged side by side, so that when the flexible screen assembly 20 is bent, the first limiting portion 321 does not affect the bending performance of the flexible screen assembly 20.

[0055] Furthermore, two adjacent first limiting portions 321 are spaced apart from each other to avoid interference between the two adjacent first limiting portions 321 when the flexible screen assembly 20 is bent, thereby preventing the bending performance of the flexible screen assembly 20 from being affected.

[0056] Please refer to Fig.12 and Fig.13 , Fig.12 is a structural schematic diagram of a guide and limit assembly in an electronic device provided by another embodiment of the present application, Fig.13 yes Fig.12 A cross-sectional schematic diagram of the guide limit assembly shown. In the second embodiment, the first limit portion 321 includes one or more rack structures 321b, and the second limit portion 322 includes one or more external gear structures 322b, and the rack structures 321b correspond to and mesh with the external gear structures 322b one by one, so that the flexible screen assembly 20 fits on the guide member 31.

[0057] Optionally, the guide member 31 includes a rotating shaft structure 311, and the external gear structure 332b is sleeved on the rotating shaft structure 311. The rotating shaft structure 311 is rotatably connected to the second shell 12, so that the external gear structure 322b can rotate with the rotating shaft structure 311 to meet the meshing of the rack structure 321b and the external gear structure 322b, so that the movement of the flexible screen assembly 20 is smoother.

[0058] Furthermore, the guide member 31 also includes a plurality of sleeve structures 312 , which are fixedly arranged at intervals on the rotating shaft structure 311 , and each outer gear structure 322 b is fixed between two adjacent sleeve structures 312 to achieve position limiting fixation of the sleeve structures 312 .

Fig.16 yes Fig.14A schematic front view of the first limiting portion in the guide limiting assembly is shown.

[0060] In embodiment three, the first limiting portion 321 is a limiting clip structure 321c, and the second limiting portion 322 is a circular limiting slot structure 322c opened on the guide portion 310. When the first limiting portion 321 corresponds to and is clamped on the second limiting portion 322, the flexible screen assembly 20 is attached to the guide member 31 to achieve the limitation of the flexible screen assembly 20.

[0061] Optionally, the number of the first limiting portions 321 is at least two and at least two first limiting portions 321 are arranged in parallel and spaced apart, and the number of the second limiting portions 322 corresponds to the number of the first limiting portions 321. When the first limiting portions 321 correspond to and are clamped on the second limiting portions 322, on the one hand, the surface stress of the flexible screen assembly 20 is constrained to between adjacent first limiting portions 321, and on the other hand, the first limiting portions 321 can share the surface stress of the flexible screen assembly 20 to reduce the possibility of the flexible screen assembly 20 arching.

[0062] In this embodiment, the guide member 31 includes a rotating shaft structure 311, and the guide portion 310 is located on the rotating shaft structure 311. The rotating shaft structure 311 is rotatably connected to the second shell 12, so that when the relative movement of the first shell 11 and the second shell 12 drives the flexible screen assembly 20 to move, the flexible screen assembly 20 can drive the rotating shaft to rotate, so as to reduce the friction between the flexible screen assembly 20 and the guide member 31, so that the movement of the flexible screen assembly 20 is smoother.

[0063] Furthermore, the surface of the limiting card strip structure 321c facing away from the flexible screen assembly 20 is serrated, so that the limiting card strip structure 321c can bend along with the flexible screen assembly 20. Specifically, it can be bent into an arc shape corresponding to the limiting card slot structure 322c, and be clamped in the corresponding limiting card slot structure 322c, thereby realizing the clamping of the limiting card strip structure 321c and the limiting card slot structure 322c, and further realizing the limitation of the flexible screen assembly 20.

[0064] In a variation of this embodiment, the guide member 31 is fixedly connected to the second housing 12, or the guide member 31 is integrally formed with the second housing 12.
