[0043] Please combine Figure 1 and Figure 2As shown, the electronic device 10 of this embodiment includes a fixed shell 100, a movable shell 200 and a flexible display screen 300, and the movable shell 200 is slidably connected to the fixed shell 100. A circuit board (not shown) and a battery (not shown) can be arranged in the storage space enclosed by the fixed shell 100 and the movable shell 200. The circuit board can integrate the processor, power management module, storage unit and baseband chip of the electronic device 10. The flexible display screen 300 is communicatively connected to the circuit board, and the battery can power the flexible display screen 300 and the electronic components on the circuit board. Of course, the electronic device 10 can also include a camera module, which is communicatively connected to the circuit board, and the battery can power the camera module. It can be understood that the electronic device 10 of the embodiment of the present application can be, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic device 10. In the embodiment of the present application, a mobile phone is taken as an example for illustration.

[0044] Combine Figure 1 and Figure 2 As shown, in the embodiment of the present application, the movable shell 200 is slidably connected to the fixed shell 100, so that the movable shell 200 can slide relative to the fixed shell 100 to a first position (such as Figure 1 as shown) and the second position (as Figure 2 As shown). When the movable shell 200 is in the second position, the electronic device 10 is in an expanded state and can obtain a relatively large display area, so as to enhance the user experience of the electronic device 10. When the movable shell 200 is in the first position, the electronic device 10 is in a folded state and has a relatively small external size, which is convenient for carrying. It will be understood that in the embodiments of the present application hereinafter, the first position, the second position and similar expressions all refer to the relative position of the fixed shell 100 and the movable shell 200. To simplify the expression, “the movable shell 200 is in the first position” or “when in the first position” and similar expressions refer to that the movable shell 200 is in the first position relative to the fixed shell 100, and “the movable shell 200 is in the second position” or “when in the second position” and similar expressions refer to that the movable shell 200 is in the second position relative to the fixed shell 100.

[0045] Combine Figures 1 to 4In this embodiment, the fixed housing 100 has a first side 110 and a second side 120 opposite the first side 110. Using the second position as a reference, the first side 110 and the second side 120 of the fixed housing 100 can be more clearly identified. Taking the figure as an example, when the movable housing 200 is in the second position, the leftmost side of the electronic device 10 in the width direction is the first side 110 of the fixed housing 100, and the rightmost side of the fixed housing 100 in the width direction of the electronic device 10 is the second side 120 of the fixed housing 100. Therefore, the process of the movable housing 200 sliding from the first side 110 to the second side 120 is the process of the movable housing 200 moving from the first position to the second position, thereby bringing the electronic device 10 into the expanded state. The process of the movable housing 200 sliding from the second side 120 to the first side 110 is the process of the movable housing 200 moving from the second position to the first position, thereby bringing the electronic device 10 into the collapsed state.

[0046] The flexible display 300 may include a fixed portion 310 and a free portion 320 that are arranged relative to each other. The fixed portion 310 is disposed on the fixed housing 100 and is fixed relative to the fixed housing 100. The free portion 320 is accommodated within the storage space, so that a portion of the flexible display 300 is hidden within the storage space, and the hidden portion of the flexible display 300 is not used for display. In other words, the movement of the movable housing 200 relative to the fixed housing 100 can expose the partially hidden flexible display 300 so that it can be used for display, or retract the exposed portion of the flexible display 300 into the storage space and hide it.

[0047] It is understood that in the embodiments of the present application, the relative fixed positions of two objects means that the two objects cannot produce relative movement under normal circumstances or the relative movement between the two objects is negligible. The two objects with relatively fixed positions can be physically directly connected or indirectly connected through an intermediate structure. Taking the fixing portion 310 and the fixed shell 100 as an example, the relative fixed positions of the fixing portion 310 and the fixed shell 100 can be directly in contact with the fixed shell 100, such as by using threaded fasteners or clamping to achieve direct fixation of the fixing portion 310 and the fixed shell 100, or the fixing portion 310 can be indirectly fixed to the fixed shell 100 through structures such as an adhesive layer, an intermediate connecting plate, etc.

[0048] It is understood that the fixed portion 310 and the free portion 320 can be distinguished as follows: when the movable shell 200 is in the first position, the portion of the flexible display 300 exposed between the movable shell 200 and the fixed shell 100 is the fixed portion 310 of the flexible display 300, and the hidden portion of the flexible display 300 is the free portion 320. In some embodiments, when the movable shell 200 is in the first position, the exposed fixed portion 310 is generally rectangular, and its size can be comparable to the size of a typical smartphone display, making the electronic device 10 portable and convenient to use.

[0049] Furthermore, the movable shell 200 may include a back cover (not shown), which covers the free portion 320 of the flexible display screen 300 when in the first position. The back cover may be provided with a light-transmitting area, and part of the flexible display screen 300 that is hidden in the first position may also be used for display, so that the user can view the information displayed on the flexible display screen 300 from the light-transmitting area, thereby expanding the use scenario of the electronic device 10. For example, in this embodiment, the electronic device 10 does not need to be provided with a front camera, and a rear-mounted camera module can be used to achieve functions such as selfies and video calls. The light-transmitting area may be made of transparent glass, or it may be formed by an opening in the back cover. After the movable shell 200 slides to the second position relative to the fixed shell 100, at least part of the flexible display screen 300 accommodated in the storage space is exposed for display, so that the electronic device 10 has a relatively large display area to enhance the user experience.

[0050] Combine Figures 3 to 6 As shown, specifically in an embodiment of the present application, the electronic device 10 further includes a screen adjustment mechanism 400, which is connected between the movable shell 200 and the flexible display screen 300, and is used to drive the flexible display screen 300 to move and fold when the movable shell 200 slides relative to the fixed shell 100, and maintain the flexible display screen 300 in a tensioned state.

[0051] Specifically, one end of the flexible display screen 300 is fixedly connected to the fixed housing 100, and the other end is connected to the screen adjustment mechanism 400. It is understood that the entire fixed portion 310 of the flexible display screen 300 may be fixed to the fixed housing 100, or only a portion of the fixed portion 310 may be fixed to the fixed housing 100, for example, the edge of the fixed portion 310 farthest from the free portion 320 may be fixed to the fixed housing 100, or the periphery of the fixed portion 310 may be fixed to the fixed housing 100. It is understood that the entire free portion 320 of the flexible display screen 300 may be fixed to the screen adjustment mechanism 400, or only a portion of the free portion 320 may be fixed to the screen adjustment mechanism 400, for example, the edge of the free portion 320 farthest from the fixed portion 310 may be fixed to the screen adjustment mechanism 400.

[0052] Combine Figure 1 、 Figures 4 to 6 As shown, in the embodiment of the present application, the screen adjustment mechanism 400 includes a recovery plate 410, a tensioning belt 420, and a fixing member 430. The recovery plate 410 is connected to the flexible display screen 300. The tensioning belt 420 has a fixed end 421 and a movable end 422 opposite the fixed end 421. The fixed end 421 is used to connect to the fixed housing 100. The fixing member 430 is connected to the movable end 422. After connecting to the recovery plate 410, the fixing member 430 and the recovery plate 410 jointly clamp the movable end 422. In this way, by connecting the fixing part 430 and the movable end 422 together, and then connecting the fixing part 430 and the recovery plate 410, and at the same time making the two clamp the movable end 422 together, a quick and stable connection of the tensioning belt 420 and the recovery plate 410 is achieved. In addition, since the flexible display screen 300 is connected to the recovery plate 410 and the fixed end 421 is connected to the fixed shell 100, the movable end 422 is connected to the flexible display screen 300 through the recovery plate 410, and the tensioning belt 420 applies a tensioning effect to the flexible display screen 300 via the recovery plate 410. The structure of the screen adjustment mechanism 400 is simple, and the assembly operation is simple and easy, which helps to improve assembly efficiency.

[0053] Specifically, the recovery plate 410 is slidably connected to the movable housing 200. As the movable housing 200 moves from the first position to the second position, the movable housing 200 can drive the flexible display 300 and the recovery plate 410 to overcome the tension of the tensioning belt 420 and move, thereby exposing the partially hidden flexible display 300 and enabling it to be used for display. Furthermore, as the movable housing 200 moves from the second position to the first position, the tension of the tensioning belt 420 drives the recovery plate 410 and the flexible display 300 to move, thereby folding and concealing the partially exposed flexible display 300. As the flexible display 300 gradually becomes exposed or folded and concealed, the tensioning belt 420 can exert tension on the flexible display 300, maintaining it in a tensioned state.

[0054] It will be appreciated that a roller (not shown) connected to the movable housing 200 may be provided, and the movable housing 200 may move synchronously with the roller. After passing around the roller, the flexible display screen 300 is connected to the recovery plate 410 and the fixed housing 100 at both ends. Therefore, as the movable housing 200 moves from the first position to the second position, the movable housing 200 drives the roller to move, gradually exposing the flexible display screen 300. The recovery plate 410 moves faster than the movable housing 200, causing it to slide relative to the movable housing 200. Simultaneously, due to the tensioning action of the tensioning belt 420, the flexible display screen 300 is pressed against the roller, thereby being tensioned. During the movement of the movable housing 200 from the second position to the first position, the tensioning action of the tensioning belt 420 also causes the flexible display screen 300 to gradually collapse and hide, pressing against the roller, thereby being tensioned.

[0055] Continue to combine Figure 1 、 Figures 4 to 6 As shown, specifically in the present application, the fixing member 430 includes a fixing plate 431, a tongue 432, and a limiting post (not shown). The fixing plate 431 is connected to the movable end 422, the tongue 432 is connected to the fixing plate 431, and is plugged into the recovery plate 410. The limiting post passes through the fixing plate 431, the movable end 422, and the recovery plate 410 in sequence. Since the tongue 432 is connected to the recovery plate 410 by plugging, and the limiting post can pass through the fixing plate 431, the movable end 422, and the recovery plate 410, thereby limiting the position of the three. In this way, under the combined action of plugging and limiting, a stable connection between the fixing member 430 and the recovery plate 410 can be achieved, and the disassembly operation is simple and easy.

[0056] In the present application, the tongue 432 and the fixed plate 431 are formed in one piece. It is understood that in other embodiments, the tongue 432 and the fixed plate 431 can also be pre-connected together by an intermediate connector. It is understood that the recovery plate 410 is provided with a slot 411, and the tongue 432 can be inserted into the slot 411 or guided out of the slot 411. In this way, the tongue 432 can abut against the slot 411 in a direction perpendicular to the direction of insertion into the slot 411, thereby limiting the fixed plate 431 in a direction perpendicular to the direction of insertion into the slot 411. It is understood that the fixed plate 431 is provided with a first through hole 433, the movable end 422 is provided with a second through hole 423, and the recovery plate 410 is provided with a third through hole 412. The limiting post passes through the first through hole 433, the second through hole 423 and the third through hole 412 in sequence, so that the limiting post limits the fixed plate 431, the movable end 422 and the recovery plate 410 in a radial direction. It can be understood that the first through hole 433, the second through hole 423 and the third through hole 412 are connected to form a limiting groove for accommodating the limiting column, and the direction from the inside of the limiting column to the inner wall of the limiting groove is the radial direction of the limiting column.

[0057] Furthermore, the tensioning belt 420 can apply an elastic force along a first direction to the recovery plate 410. The tongue 432 is inserted into the recovery plate 410 in a direction opposite to the first direction, and the limiting post is inserted through the recovery plate 410 in a direction perpendicular to the first direction. It is understood that the elastic force applied by the tensioning belt 420 to the recovery plate 410 will ultimately be transmitted to the flexible display 300 to maintain the flexible display 300 in a tensioned state. The tensioning belt 420 can be inherently elastic and able to output an elastic force when stretched, or an additional elastic component can be provided to act on the tensioning belt 420 through the elastic component, thereby causing the tensioning belt 420 to output an elastic force.

[0058] The positive direction of the X-axis is defined as the direction in which the movable housing 200 slides relative to the fixed housing 100 from the second position to the first position. The negative direction of the X-axis is defined as the direction in which the movable housing 200 slides relative to the fixed housing 100 from the first position to the second position. The Z-axis is the thickness direction of the electronic device 10. The Y-axis, X-axis, and Z-axis are perpendicular to each other. It can be understood that the first direction is specifically along the positive direction of the X-axis, and the tongue 432 is inserted into the recovery plate 410 along the reverse direction of the X-axis. In this way, after the tongue 432 is injected into the recovery plate 410, the recovery plate 410 limits the fixed plate 431 along the positive and reverse directions of the Z-axis to prevent the fixed plate 431 from separating from the recovery plate 410 along the Z-axis, and the limiting column passes through the recovery plate 410 along the Z-axis, so that the recovery plate 410 and the fixed plate 431 are locked along the positive and reverse directions of the X-axis. In this way, even if the flexible display screen 300 generates a rebound force to restore the deformation due to deformation, and the rebound force acts on the recovery plate 410, the tongue 432 and the limiting column can work together to stably lock the recovery plate 410 and the fixed plate 431 together and prevent them from separating.

[0059] Furthermore, there are multiple limiting posts, which are spaced apart. There are multiple tongues 432, which are spaced apart on the fixed plate 431. Specifically, in the present application, there are four limiting posts, which are arranged in a roughly trapezoidal pattern, and two tongues 432, which are spaced apart along the Y-axis. By providing multiple limiting posts and multiple tongues 432, the purpose of stable positioning can be achieved. In other embodiments, the limiting posts are not limited to four, and the number of tongues 432 is not limited to two.

[0060] Specifically, the movable end 422 is in the shape of a sheet, and the fixed plate 431 and the recovery plate 410 are both in the shape of a plate. In this way, after the fixed plate 431 and the recovery plate 410 are connected, the two clamp the movable end 422 from the opposite sides of the movable end 422, and the fixed plate 431 and the movable end 422 are in surface-to-surface contact, and the movable end 422 and the recovery plate 410 are also in surface-to-surface contact, thereby improving the stability of the connection between the movable end 422 and the recovery plate 410.

[0061] Continue to combine Figure 1 、 Figures 4 to 6 As shown, in the embodiment of the present application, the tensioning belt 420 includes a screen-adhering portion 424 connected to the movable end 422. The screen-adhering portion 424 and the recovery plate 410 are respectively connected to opposite sides of the flexible display 300. It will be appreciated that the connection between the flexible display 300 and the screen adjustment mechanism 400, connected to the screen-adhering portion 424 and the recovery plate 410 on opposite sides, can improve the reliability of the connection between the flexible display 300 and the screen adjustment mechanism 400 and prevent the flexible display 300 from warping due to the rebound force generated by deformation. Furthermore, the screen-adhering portion 424 and the recovery plate 410 are respectively bonded to opposite sides of the flexible display 300, thereby achieving a quick and reliable connection without the need to remove material from the flexible display 300.

[0062] Furthermore, the recovery plate 410 is provided with a receiving groove 413, into which both the fixed plate 431 and the movable end 422 are received. The movable end 422 and the screen-adhering portion 424 are arranged in a stepped manner. It is understood that, since the receiving groove 413 is provided in the recovery plate 410, the slot 411 for accommodating the tongue 432 can be located at the base of the receiving groove 413, providing space for the slot 411. Furthermore, after the movable end 422 is confined within the receiving groove 413, it needs to bend and extend from the receiving groove 413 before connecting to the screen-adhering portion 424. The connection between the movable end 422 and the screen-adhering portion 424 is arranged in a stepped manner, i.e., the connection between the two is generally in a "Z" shape. This also reduces the mutual influence between the movable end 422 and the screen-adhering portion 424.

[0063] Furthermore, the recovery plate 410 is stepped, having a thin portion 414 and a thick portion 415. The flexible display 300 is specifically connected to the thin portion 414, while the receiving groove 413 is provided in the thick portion 415. Thus, along the thickness direction of the recovery plate 410, it provides accommodation space for the fixed plate 431 and the movable end 422, as well as for the flexible display 300. As a result, the recovery plate 410, the fixed plate 431, the movable end 422, and the flexible display 300 can be assembled together more compactly without occupying a large amount of additional space in the Z-axis direction, thereby contributing to the reduction in thickness of the electronic device 10.

[0064] In the embodiment of the present application, the tensioning belt 420 includes a handle portion 425, which is connected to the side of the screen sticking portion 424 away from the movable end 422 and is removed after the fixing member 430 is connected to the recovery plate 410. It can be understood that the handle portion 425 can play an auxiliary role in the assembly stage, but needs to be removed after use (e.g., Figure 1As shown in the figure, it is understandable that due to the tensioning force of the tensioning belt 420, it is difficult to manually tighten the screen-adhering portion 424. By providing the handle portion 425, a larger operating space is provided for the human hand. By steadily tightening the handle portion 425, the tongue 432 is smoothly inserted into the recovery plate 410. After that, the limit column can quickly pass through the fixed plate 431, the movable end 422, and the recovery plate 410, thereby achieving a smooth and quick connection between the fixing member 430 and the recovery plate 410. Specifically, the handle portion 425 has a "T" shape to facilitate human grip.

[0065] Combined with 1. Figures 5 to 8 As shown, in this embodiment of the present application, the screen adjustment mechanism 400 includes an elastic assembly 440 mounted on the movable housing 200. The elastic assembly 440 acts on the tensioning belt 420, enabling the tensioning belt 420 to exert an elastic force on the flexible display 300. Specifically, the elastic assembly 440 includes an elastic member 441 and a resisting member 442. Under the elastic action of the elastic member 441, the resisting member 442 abuts against the region of the tensioning belt 420 between the fixed end 421 and the movable end 422, thereby tensioning the tensioning belt 420. Specifically, the elastic member 441 elastically acts on the resisting member 442 in the positive direction of the X-axis, causing the resisting member 442 to abut against the tensioning belt 420. This causes the tensioning belt 420 to exert an elastic force in the positive direction of the X-axis on the recovery plate 410 and the flexible display 300, thereby maintaining tension on the flexible display 300. Specifically, the elastic member 441 is a spring that pushes the resisting member 442 in the positive direction of the X-axis. In other embodiments, the elastic member 441 may also be other types of elastic structural members such as a tension spring and an elastic pad.

[0066] Furthermore, the elastic assembly 440 includes a support frame 443, a resisting member 442 is mounted on the support frame 443, and an elastic member 441 is connected to one end of the support frame 443 away from the resisting member 442. The resisting member 442 is a roller rotatably connected to the support frame 443. By providing the support frame 443, the resisting member 442 can be rotated relative to the support frame 443, thereby generating rolling friction between the resisting member 442 and the tension belt 420. This reduces frictional resistance when the tension belt 420 and the resisting member 442 move relative to each other, allowing the tension belt 420 to move more smoothly. In addition, a first guide post 444 is provided at one end of the support frame 443 away from the supporting member 442, and the movable shell 200 is provided with a second guide post 210. One end of the elastic member 441 is sleeved on the first guide post 444, and the other end is sleeved on the second guide post 210. With the cooperation of the first guide post 444 and the second guide post 210, the elastic member 441 is maintained to extend and retract along the X-axis, ensuring that the elastic member 441 can extend and retract relatively smoothly, and also facilitating the installation of the elastic member 441 and the support frame 443.

[0067] Furthermore, the movable shell 200 is provided with a mounting slot 220 extending therethrough, and the supporting member 442 is mounted in the mounting slot 220. The fixed end 421 extends through the mounting slot 220 from one side of the movable shell 200 and is then connected to the fixed shell 100. After the fixed end 421 extends through the mounting slot 220, the fixed end 421 and the movable end 422 are respectively located on opposite sides of the movable shell 200. Furthermore, the range of motion of the tensioning band 420 is limited to the mounting slot 220, allowing it to maintain stable contact with the supporting member 442, thereby avoiding the risk of the supporting member 442 and the tensioning band 420 becoming detached from each other. Specifically, the movable shell 200 is provided with a guide slot 230 communicating with the mounting slot 220. The support frame 443 and the elastic member 441 are disposed within the guide slot 230. Guided by the guide slot 230, the support frame 443 can only move along the X-axis, thereby driving the supporting member 442 to move along the X-axis within the mounting slot 220. Furthermore, the movable shell 200 is further provided with a cover plate 240 , which covers the guide groove 230 , thereby confining the support frame 443 and the elastic member 441 in the guide groove 230 to prevent the support frame 443 and the elastic member 441 from escaping from the guide groove 230 .

[0068] In addition, the combination of the tensioning belt 420 and the supporting member 442 is in the form of a movable pulley. Therefore, the movement stroke of the movable end 422 along the X-axis is always twice the movement stroke of the movable plate along the X-axis, and the movement stroke of the movable end 422 can just meet the needs of the flexible display screen 300 connected to the recovery plate 410 to move along the X-axis.

[0069] Specifically, the fixed end 421 of the tensioning band 420 is connected to the second side 120 of the fixed housing 100. Thus, during the movement of the movable housing 200 from the first position to the second position, the length of the tensioning band 420 between the fixed end 421 and the abutting member 442 gradually decreases, while the length of the tensioning band 420 between the abutting member 442 and the movable end 422 gradually increases, thereby achieving the release of the flexible display 300. Specifically, the electronic device 10 includes a gasket 500 and a locking member (not shown). The locking member passes through the gasket 500 and the fixed end 421 and is connected to the fixed housing 100. The locking member can be a screw that is threadedly connected to the fixed housing 100 after passing through the gasket 500 and the fixed end 421, and can press the gasket 500 against the fixed end 421, thereby achieving a fixed connection between the fixed end 421 and the fixed housing 100.

[0070] Specifically, the screen adjustment mechanism 400 is generally located on the side of the movable shell 200 away from the fixed shell 100, which can improve the assembly convenience and also allow a larger space between the movable shell 200 and the fixed shell to install electronic devices such as batteries and circuit boards, thereby improving space utilization.

[0071] Combine Figures 1 to 9As shown, the specific operation method and steps for assembling the electronic device 10 are as follows.

[0072] S100, connect one end of the flexible display screen to the fixed shell, and the other end to the recycling board.

[0073] Specifically, one end of the flexible display 300 is bonded to the fixed housing 100, and the other end is bonded to the recovery plate 410. By bonding the flexible display 300, a reliable connection is ensured while also avoiding operations such as drilling holes in the flexible display 300, thereby preventing damage to the flexible display 300. It should be noted that in other embodiments, other methods can be used to connect the ends of the flexible display 300 to the fixed housing 100 and the recovery plate 410.

[0074] S200, connecting the fixed end of the tensioning belt to the fixed shell.

[0075] Specifically, the fixed end 421 must first be inserted through the mounting slot 220 of the movable shell 200, so that the fixed end 421 and the movable end 422 are located on opposite sides of the movable shell 200, and then the fixed end 421 is connected to the fixed shell 100. Furthermore, the fixed end 421 is specifically connected to the second side 120 of the fixed shell 100. When connecting the fixed end 421 to the fixed shell 100, the gasket 500 must first be bonded to the fixed end 421. The locking member must then be inserted through the gasket 500 and the fixed end 421 and then connected to the fixed shell 100. This arrangement allows the gasket 500 to be securely connected to the fixed end 421, thereby increasing the thickness of the fixed end 421 and thereby strengthening the fixed end 421, preventing the fixed end 421 from separating from the fixed shell 100 due to pulling. Furthermore, after the locking member is connected to the fixed shell 100, the gasket 500 also prevents the locking member from loosening.

[0076] S300, connecting the fixing piece to the movable end of the tensioning belt.

[0077] By preferentially connecting the fixing member 430 and the movable end 422 together, it can be helpful to quickly connect the fixing member 430 to the recovery plate 410. Specifically, the fixing member 430 is bonded to the movable end 422. Furthermore, specifically, the fixing plate 431 in the fixing member 430 is bonded to the movable end 422. After the fixing plate 431 and the movable end 422 have been bonded, it is convenient to connect the tongue 432 and the limiting column to the recovery plate 410 respectively. In addition, after the fixing plate 431 is bonded to the movable end 422 of the tensioning belt 420, the fixing plate 431 can be firmly connected to the movable end 422, which in disguise increases the thickness of the movable end 422, thereby improving the strength of the movable end 422 and preventing the movable end 422 from being separated from the recovery plate 410 due to pulling.

[0078] S400, connect the fixing member to the recovery plate, and clamp the movable end together with the recovery plate.

[0079] After the fixing member 430 and the recovery plate 410 are quickly connected, the two can also jointly clamp the movable end 422, thereby achieving a quick and stable connection between the movable end 422 and the recovery plate 410. Specifically, the tongue 432 in the fixing member 430 is first plugged into the recovery plate 410, and then the limiting post is sequentially inserted through the fixing plate 431, the movable end 422, and the recovery plate 410. In this way, the fixing plate 431 and the recovery plate 410 can stably clamp the movable end 422. Because the tongue 432 and the recovery plate 410 are connected by plugging, and the limiting post can be inserted through the fixing plate 431, the movable end 422, and the recovery plate 410 to limit the three, in this way, the combined effect of plugging and limiting can achieve a stable connection between the fixing member 430 and the recovery plate 410, while the disassembly operation is simple and easy.

[0080] Furthermore, when plugging the tongue piece 432 into the recovery plate 410, the tongue piece 432 is plugged into the recovery plate 410 by pulling the handle portion 425. Since the tensioning force of the tensioning belt 420 is exerted, it is difficult for a person to manually pull the movable portion to plug the tongue piece 432 into the recovery plate 410. By providing the handle portion 425, a larger operating space is provided for the person's hand. By stably pulling the handle portion 425, the tongue piece 432 is smoothly inserted into the recovery plate 410, and then the limiting column can be quickly inserted into the fixed plate 431, the movable end 422 and the recovery plate 410, thereby achieving a smooth and quick connection between the fixing member 430 and the recovery plate 410.

[0081] In addition, after the limiting column is sequentially passed through the fixed plate 431, the movable end 422, and the recovery plate 410, two further steps are included: first, removing the handle portion 425; and second, bonding the screen-adhering portion 424 to the side of the flexible display 300 facing away from the recovery plate 410. After the auxiliary tongue 432 of the handle portion 425 is plugged into the recovery plate 410, the handle portion 425 can be removed to prevent it from taking up space or causing entanglement with other internal components. Bonding the screen-adhering portion 424 to the side of the flexible display 300 facing away from the recovery plate 410 can improve the reliability of the connection between the flexible display 300 and the screen adjustment mechanism 400, preventing the flexible display 300 from warping due to the rebound force generated by deformation to restore the deformation. In addition, the bonding operation is fast and reliable, and it can avoid punching holes in the flexible display 300.

[0082] S500, slidingly install the recovery plate on the movable shell.

[0083] After the screen adjustment mechanism 400 is assembled, the recovery plate 410 is assembled with the movable housing 200 so that the recovery plate 410 slides relative to the movable housing 200 along the X-axis direction, thereby releasing or retracting the flexible display screen 300.

[0084] S600, slide the movable shell onto the fixed shell.

[0085] After the screen adjustment mechanism 400 is assembled, the movable shell 200 and the fixed shell 100 are finally assembled together, so that the movable shell 200 slides relative to the fixed shell 100 along the X-axis direction, thereby achieving the purpose of expanding or contracting the electronic device 10. It should be noted that in this application, the important parts are the connections between the various components in the screen adjustment mechanism 400, the connection between the screen adjustment mechanism 400 and the flexible display screen 300, and the connection between the tensioning belt 420 in the screen adjustment mechanism 400 and the fixed shell 100. The installation of the various electronic components in the electronic device 10 is not described here.

[0086] In the above-mentioned electronic device 1, by connecting the fixing part 430 and the movable end 422 together, and then connecting the fixing part 430 and the recovery plate 410, and at the same time making the two jointly clamp the movable end 422, a quick and stable connection of the tensioning belt 420 and the recovery plate 410 is achieved. In addition, since the two ends of the flexible display screen 300 are respectively connected to the fixed shell 100 and the recovery plate 410, and the fixed end 421 is connected to the fixed shell 100, the movable end 422 is connected to the flexible display screen 300 through the recovery plate 410, and the tensioning belt 420 applies a tensioning effect to the flexible display screen 300 via the recovery plate 410. The structure of the screen adjustment mechanism 400 is simple, and the assembly operation is simple and easy, which helps to improve assembly efficiency.
