Referring to fig. 1 and fig. 2, an electronic device 100 according to an embodiment of the present disclosure may include two modes. The first configuration is a configuration (as shown in fig. 1) in which the first housing 11 and the second housing 12 are fitted together, that is, a configuration in which the electronic device 100 is located when the first housing 11 and the second housing 12 are close to each other and move to an extreme position, in which the flat portion 21 of the flexible display 20 is exposed outside the housing assembly 10, the expanded portion 22 is substantially completely hidden inside the housing assembly 10, and the display area of the electronic device 100 is small and convenient to carry. The second configuration is a configuration in which the second shell 12 moves away from the first shell 11 to drive the expansion portion 22 of the flexible display screen 20 to gradually expand out of the shell assembly 10 (see fig. 2), and in the second configuration, the second portion of the flexible display screen 20 at least partially expands out of the shell assembly 10 to form a display portion of the electronic device 100 together with the flat portion 21, so that the display area of the electronic device 100 is larger to provide a better display effect for a user.

In the embodiment of the present application, the "display area" refers to an area of a portion of the flexible display 20 exposed outside the case assembly 10 for display.

In the embodiment of the present application, the fact that the extension portion 22 can be hidden in the case assembly 10 is understood that the extension portion 22 can be housed in the internal space of the case assembly 10 and is not exposed, or the fact that the extension portion 22 can be hidden in the back surface of the case assembly 10 and is exposed from the back surface is described herein by way of example, the extension portion 22 can be housed in the internal space of the case assembly 10 and is not exposed.

Specifically, in the illustrated embodiment, the first housing 11 is slidably connected to the second housing 12, and the extension portion 22 of the flexible display 20 may be disposed inside the housing assembly 10 in a hidden configuration. Referring to fig. 3, in the first configuration, the extended portion 22 of the flexible display screen 20 is not used for display, and only the flat portion 21 is used for display. The flexible display 20 may be moved when the second housing 12 moves away from the first housing 11, such that the extension portion 22 of the flexible display 20 is at least partially pulled out of the housing assembly 10 to switch to the second configuration. In the second configuration, the extension portion 22 is at least partially pulled out of the housing assembly 10, and the flat portion 21 and the extension portion 22 are simultaneously used for displaying, thereby changing the display area of the electronic device 100.

It is understood that the driving mechanism 30 is installed in the first housing 11 to drive the second housing 12 to move relative to the first housing 11, and the flexible display 20 is moved when the second housing 12 moves relative to the first housing 11, so that the electronic device 100 can be switched between two configurations. In some embodiments, the first casing 11 of the electronic device 100 may serve as a main supporting structure of the electronic device 100, and the first casing 11 may accommodate therein a camera, a speaker, a circuit board, and the battery 40. Additionally, in some embodiments, the second shell 12 may be slightly smaller than the first shell 11, such that the second shell 12 may also be entirely collapsed inside the first shell 11. In some embodiments, the first housing 11 and the second housing 12 may have similar shapes, and the second housing 12 and the first housing 11 cooperate to form a complete support structure, which makes the flexible display 20 symmetrical and beautiful when unfolded.

During the switching of the two forms, the motor 31 is used for providing a driving force, the motor 31 is connected with the synchronizing shaft 32 to drive the synchronizing shaft 32 to rotate, and the first gear 33 and the second gear 34 are respectively installed at the two ends of the synchronizing shaft 32, so that the first gear 33, the second gear 34 and the synchronizing shaft 32 can rotate synchronously. The first rack portion 35 is engaged with the first gear 33 while the second rack portion 36 is engaged with the second gear so that the first gear 33 and the second gear 34 can move the first rack portion 35 and the second rack portion 36. Since the first rack portion 35 and the second rack portion 36 are symmetrically disposed on the second shell 12 with respect to the sliding direction of the second shell 12, and the first rack portion 35 and the second rack portion 36 both extend along the sliding direction of the second shell 12, the first gear 33 and the second gear 34 driving the first rack portion 35 and the second rack portion 36 to move can make the second shell 12 perform sliding movement with respect to the first shell 11, so that the expansion portion 22 is at least partially expanded out of the shell assembly 10 or retracted into the shell assembly 10.

Further, referring to fig. 3, 7 and 8, the synchronizing shaft 32 and the motor 31 may be disposed at an edge position of the first and second cases 11 and 12, so that the motor 31 and the synchronizing shaft 32 are located at a middle portion of the first and second cases 11 and 12 when the second case 12 is moved away from the first case 11 to the second configuration. In this way, space can be saved for other components, and at the same time, the stroke of the first rack portion 35 and the second rack portion 36 can be made as long as possible to increase the display area of the flexible display 20. Referring to fig. 9, the first gear 33 is engaged with the first rack portion 35, and the first gear 33 is fixed to the synchronizing shaft 32, so that the first gear 33 can push out the first rack portion 35 during rotation, the first toothed portion 35 is integrally formed with the first sliding portion 351, and the first sliding portion 351 can drive the second housing 12 to move, so that the second housing 12 slides relative to the first housing 11. Of course, the second gear 34 and the second rack portion 36 are connected in the same manner.

It is understood that the saved space can be used to reduce the overall size of the electronic device 100, so that the electronic device 100 is more compact and more delicate. In some embodiments, the saved space can be used to increase the accommodation of the battery 40, so that the electronic device 100 can be used for a longer time, and the user experience can be improved.

In the present embodiment, the motor shaft of the motor 31 and the synchronizing shaft 32 may be coaxially designed, such that the motor 31 and the synchronizing shaft 32 are simultaneously located at the edge of the first housing 11, which may provide more reasonable space. Of course, in other embodiments, the motor shaft of the motor 31 and the synchronizing shaft 32 may be vertically designed such that the overall arrangement of the driving mechanism 30 is substantially L-shaped. The specific placement design of the driving mechanism 30 is not limited herein, and the requirements can be met.

The electronic device 100 in the embodiment of the present application may be a mobile terminal device such as a smart phone or a tablet computer, or may be a device that can be equipped with a display device such as a game device, a vehicle-mounted computer, a notebook computer, or a video player, and is not specifically shown here.

In addition, in the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, "a plurality" means two or more unless specifically defined otherwise.

It should be noted that in the description of the present application, it is to be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner" and "outer" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present application. In addition, it should be noted that, in the description of the present application, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 3 to 5, in some embodiments, the first shell 11 is formed with a first protrusion 111 and a second protrusion 112, the first protrusion 111 is formed with a first sliding slot 1111, the second protrusion 112 is formed with a second sliding slot 1121, and the second shell 12 is fixedly provided with a first sliding portion 351 and a second sliding portion 361.

The first sliding portion 351 is slidably engaged with the first sliding groove 1111, the second sliding portion 361 is slidably engaged with the second sliding groove 1121, the first rack portion 35 is formed on the first sliding portion 351 and is exposed from the first sliding groove 1111, the second rack portion 36 is formed on the second sliding portion 361 and is exposed from the second sliding groove 1121, and when the second shell 12 slides relative to the first shell 11, the first sliding portion 351 slides in the first sliding groove 1111, and the second sliding portion 361 slides in the second sliding groove 1121.

In this way, when the first rack portion 35 and the second rack portion 36 are driven by the synchronizing shaft 32, the first sliding portion 351 can slide in the first sliding slot 1111, and the second sliding portion 361 can slide in the second sliding slot 1121, so that the second housing 12 can slide relative to the first housing 11 along the direction of the sliding slot, thereby changing the form of the electronic device 100.

Specifically, the first protrusion 111 and the second protrusion 112 may be integrally formed with the first case 11, or may be separately manufactured and then attached to the first case 11. The first protrusion 111 and the second protrusion 112 form a first sliding slot 1111 and a second sliding slot 1121, respectively, so that the first sliding portion 351 and the second sliding portion 361 can slide within the first sliding slot 1111 and the second sliding slot 1121. It is understood that the second housing 12 is fixed to the first sliding portion 351 and the second sliding portion 361, and a sliding direction of the first sliding portion 351 and the second sliding portion 361 in the sliding groove is a sliding direction of the second housing 12 relative to the first housing 11.

Further, referring to fig. 9, the first and second rack portions 35 and 36 may be exposed from the slide groove to engage the first and second gears 33 and 34, so that the driving force generated by the motor 31 may be transmitted to the first and second rack portions 35 and 36 through the first and second gears 33 and 34. Specifically, the motor 31 rotates to drive the synchronizing shaft 32 to rotate, the synchronizing shaft 32 rotates to drive the first gear 33 and the second gear 34 to rotate synchronously, and the first gear 33 and the second gear 34 rotate to drive the first rack portion 35 and the second rack portion 36 to move. The first rack portion 35 and the second rack portion 36 can synchronously drive the first sliding portion 351 and the second sliding portion 361 to slide along the sliding slot, so as to push the second shell 12 to move along the sliding slot direction relative to the first shell 11, and further, the expanding portion 22 can be at least partially expanded out of the shell assembly 10 or retracted into the shell member, thereby realizing the change of the form of the electronic device 100.

In the related art, in order to ensure the stability of the second housing sliding relative to the first housing, a guide shaft or a slide rail is often required to be added along the sliding direction to limit the movement stroke of the second housing and ensure the stability of the sliding, however, the additional slide rail arranged in the housing occupies a larger space in the housing, which is not favorable for the layout of other electronic components (such as a battery and a circuit board, etc.) of the electronic device.

In the present embodiment, however, the protruding portion is formed with the slide groove, and the rack portion is formed on the sliding portion so that the sliding portion can slide in the slide groove, which is sufficiently long. The design combines the rack and the sliding rail, so that the sliding part and the rack part both play a role in driving the second shell 12 to move relative to the first shell 11, and the sliding rail has a role in ensuring the movement stability of the sliding rail. In this way, space is saved on the track to accommodate more components, for example, a larger battery 40 to improve endurance.

Referring to fig. 3 and 6, in some embodiments, a first accommodating space 113 is formed between the first protrusion 111 and the second protrusion 112, and the electronic device 100 further includes a battery 40, wherein the battery 40 is disposed in the first accommodating space 113.

In this way, the first protrusion 111, the second protrusion 112 and the synchronizing shaft 32 may enclose a first accommodating space 113, and the first accommodating space 113 is provided with the battery 40 so that the battery 40 may supply power to other components.

It can be understood that, referring to fig. 10 and 11, in order to ensure the stability of the movement of the second shell 12 relative to the first shell 11, a sufficient distance is required between the first protrusion 111 and the second protrusion 112 to ensure the balanced force when the second shell 12 moves relative to the first shell 11, so as to avoid the problem of the second shell 12 being skewed relative to the first shell 11. A first accommodating space 113 is formed between the first protrusion 111 and the second protrusion 112, and the first accommodating space 113 can accommodate the battery 40, so that the capacity of the battery 40 is large, the standby time and the service time of the electronic device 100 are increased, and the user experience is improved.

In the embodiment of the present application, the type of the battery 40 is not limited, and the battery 40 may be a lithium battery 40 or a nickel metal hydride battery 40 to meet various requirements.

Further, referring to fig. 3 and 6, in some embodiments, a second accommodating space 114 is formed between the first protrusion 111 and one side of the first shell 11, a third accommodating space 115 is formed between the second protrusion 112 and the other side of the first shell 11, and the third accommodating space 115 and the second accommodating space 114 are symmetrically disposed about the first accommodating space 113.

The electronic device 100 further includes a main board 50, the main board 50 is electrically connected to the battery 40, the main board 50 includes a first board portion 51, a second board portion 52, and a third board portion 53 connecting the first board portion 51 and the second board portion 52, the first board portion 51 is disposed in the second accommodating space 114, the second board portion 52 is disposed in the third accommodating space 115, the third board portion 53 is disposed in the first accommodating space 113, and the first board portion 51, the second board portion 52, and the third board portion 53 together enclose an avoiding space for avoiding the battery 40.

In this way, designing the main board 50 as the first plate portion 51, the second plate portion 52 and the third plate portion 53 can make the main board 50 be disposed around the battery 40, so that the battery 40 is disposed in the evasive space, and the space of the electronic device 100 is effectively utilized, so that the components of the electronic device 100 are reasonably distributed.

Specifically, the first receiving space 113 occupies a middle space of the first case 11, the second receiving space 114 and the third receiving space 115 are respectively located below and above the first receiving space 113, and the motor 31 may be placed in the second receiving space 114 or the third receiving space 115. It is understood that the parts of the main board 50 need to be electrically connected, and thus the third board portion 53 needs to be disposed in the first accommodation space 113 so that the third board portion 53 can electrically connect the first board portion 51 and the second board portion 52. That is, the first accommodating space 113 is not used for accommodating the battery 40, in one embodiment, the spaces on both sides of the first accommodating space 113 are used for accommodating the synchronizing shaft 32 and the third plate portion 53, respectively, and the battery 40 is accommodated in the space surrounded by the synchronizing shaft 32, the third plate portion 53, the first protrusion 111 and the second protrusion 112.

In some embodiments, the third plate portion 53 may be a flexible circuit board, facilitating placement of the third plate portion 53 to connect the first plate portion 51 and the second plate portion 52 in different locations.

In the embodiment of the present invention, the first accommodating space 113 may also be used for accommodating the main board 50, and the third accommodating space 115 and the second accommodating space 114 may also be used for accommodating the battery 40, which is not limited herein, and only needs to ensure the normal operation of the electronic device 100.

Referring to fig. 3 and 7, in some embodiments, the first protrusion 111 and the second protrusion 112 are formed with mounting grooves 1131, and the third plate 53 is mounted in the mounting grooves 1131.

In this way, the third plate portion 53 is disposed in the mounting groove 1131 so that the main board 50 as a whole can be fixed in the inner space of the first case 11, so that the battery 40 and the main board 50 can reasonably distribute the space.

Specifically, the first protruding portion 111 and the second protruding portion 112 are formed with an installation groove 1131 at an end away from the synchronizing shaft 32, and the installation groove 1131 can be used for installing and clamping the third plate portion 53, so as to prevent the main plate 50 from loosening.

As such, the flexible display 20 may be supported by the first and second brackets 116, 121, preventing the flexible display 20 from sagging and causing a bad experience when the user is in extended use.

Specifically, the first support plate 117 and the second support plate 122 may function to support the entire electronic device 100, protecting internal elements of the electronic device 100 from external impact and vibration. The first supporting plate 117 is disposed on one side opposite to the accommodating space, the flat portion 21 of the flexible display screen 20 is fixed on the first supporting plate 117, the first supporting plate 117 has a first supporting surface 1171, the first supporting surface 1171 is the side opposite to the accommodating space, and the flat portion 21 of the flexible display screen 20 is supported on the first supporting surface 1171. The second supporting plate 122 has a second supporting surface 1221, the second supporting surface 1221 is the surface opposite to the accommodating space, and when the second support 121 slides relative to the first support 116, the extension portion 22 of the flexible display screen 20 is supported on the second supporting surface 1221.

Further, when the second support 121 is unfolded relative to the first support 116, the first support surface 1171 and the second support surface 1221 are in the same plane, so that the flat portion 21 and the expanded portion 22 of the flexible display screen 20 are also in the same plane, and the user experience is enhanced.

Referring to fig. 12 and 13, in some embodiments, the first support plate 117 is formed with a plurality of slots 1172 extending through the first support surface 1171. The second support plate 122 is formed with a plurality of insertion portions 1222 spaced apart from each other, the insertion portions 1222 have partial second support surfaces 1221, the insertion portions 1222 are in one-to-one correspondence with the slots 1172, and the insertion portions 1222 are moved in the slots 1172 when the second housing 12 is slid with respect to the first housing 11.

In this way, the electronic device 100 in the first configuration can be tightly fitted, so that the electronic device 100 has stable structure, and the slot 1172 and the insertion portion 1222 can be fitted to stabilize the sliding process of the second shell 12 relative to the first shell 11.

Specifically, a plurality of slots 1172 arranged at intervals may be formed on the first support plate 117, a plurality of insertion portions 1222 arranged at intervals may be formed on the second support plate 122, and the insertion portion 1222 of the second support plate 122 may be matched with the slot 1172 of the first support plate 117, that is, when the second shell 12 and the first shell 11 move relatively, the insertion portion 1222 slides in the slot 1172 and the surface of the slot 1172 and the top surface of the insertion portion 1222 may be flush, so that a height difference may not be formed on the upper surfaces of the second shell 12 and the first shell 11 when the second shell 12 slides relative to the first shell 11, thereby ensuring the flatness of the electronic device 100. It should be noted that "flush" herein may be understood as the same height, or may be understood as the difference in height between the two is within the manufacturing error and the assembling error.

Further, in the first form, the insertion portion 1222 slides into the slot 1172 so that the first and second cases 11 and 12 can maintain a stable state structure. In the second configuration, the insert 1222 slides partially out of the slot 1172 so that the flexible display screen 20 can be deployed outside the housing assembly 10. In some embodiments, the second support plate 122 may further have a plurality of slots 1172 formed therein at intervals, and the first support plate 117 may have a plurality of insertion portions 1222 formed therein at intervals, which is not limited herein.

In addition, it can be understood that, in the present embodiment, the number of the slots 1172 and the insertion portions 1222 is set to ensure that the user does not collapse significantly when touching or pressing the display area of the electronic device 100, that is, when the user presses the display area (i.e., the portion of the first portion and the second portion exposed from the housing assembly 10) of the electronic device 100, the display area does not collapse significantly to ensure the operation experience, and the specific number of the slots 1172 and the insertion portions 1222 can be set according to the actual situation.

Referring to fig. 12 and 13, in some embodiments, the first housing 11 further includes a first end cap 118 and a back cap 119, the first bracket 116 is fixedly disposed in the first end cap 118, the back cap 119 is fixedly connected to the first housing 11 and covers the first bracket 116, the second housing 12 further includes a second end cap 123, and the second bracket 121 is fixedly disposed in the second end cap 123. When the extension 22 is fully seated within the housing assembly 10, the first end cap 118 is spliced to the second end cap 123, the back cap 119 is received within the first end cap 118, and when the extension 22 is at least partially exposed from within the housing assembly 10, the back cap 119 is at least partially exposed from the second end cap 123.

In this way, the first end cap 118, the back cap 119 and the second end cap 123 can absorb shock and vibration, protect various components in the internal space, and prevent the components of the electronic device 100 from being damaged.

Specifically, the first end cap 118 includes a first bottom wall covering the first accommodating space 113, the second accommodating space 114, and the third accommodating space 115 of the first case 11, and a first side wall vertically connected to the first bottom wall covering both sides of the first case 11. The first bracket 116 is secured within a first end cap 118.

The second end cap 123 includes a second bottom wall covering the back side of the second case 12 and a second side wall perpendicularly connected to the second bottom wall, the second side wall covering both sides of the second case 12 and a side away from the first case 11. The second bracket 121 is fixed within the second end cap 123.

Further, when the electronic device 100 is in the first configuration, the back cover 119 may be disposed to overlap with the extension portion 22 and hidden in the second end cover 123. When the electronic device 100 is converted into the second configuration, the back cover 119 may be at least partially exposed from the second end cover 123, so as to prevent the internal components of the electronic device 100 from being exposed from the accommodating space, and to protect other components.

It is understood that the electronic device 100 also includes optical elements such as a camera and a distance sensor, which may be disposed within the interior of the first end cap 118. In some embodiments, the first end cap 118 needs to be perforated to allow light to pass through the first end cap 118 and into the optical element. In other embodiments, the first end cap 118 may be made of a transparent material and may be transparent, so that light can enter the optical assembly through the first end cap 118.

Referring to fig. 3 and 12, in some embodiments, the second housing 12 is formed with a guiding portion 124, a middle portion of the expansion portion 22 is wound around the guiding portion 124, the electronic device 100 further includes a tensioning structure 60, the tensioning structure 60 is installed in the first housing 11 and connects an end of the expansion portion 22 away from the flat portion 21, and the tensioning structure 60 is used for tensioning the flexible display 20.

Thus, the tensioning structure 60 can tension the flexible display 20 during the process that the second housing 12 brings the extension portion 22 to be deployed out of the housing assembly 10 or retracted into the housing assembly 10, and the middle portion of the extension portion 22 is wound around the guide 124, so that the extension portion 22 is not arched and folded to ensure that the extension portion 22 can be smoothly deployed or retracted.

Further, referring to fig. 3 and 6, in some embodiments, the tensioning structure 60 includes a pulling rope 61 and a tensioning member 62, the tensioning member 62 is disposed on the second shell 12 and can move relative to the first shell 11 along with the second shell 12, one end of the pulling rope 61 is fixedly connected to the end of the expanding portion 22, the other end is fixedly connected to the first shell 11, and the stretched middle portion is wound on the tensioning member 62.

Thus, the pull rope 61 can pull the flexible display screen 20 tightly when the flexible display screen 20 is retracted, so as to prevent the flexible display screen 20 from being folded, and the tensioning member 62 can guide the auxiliary pull rope 61 to move.

Specifically, when the second shell 12 is relatively far away from the first shell 11, the tension member 62 follows the second shell 12, and one end of the pulling rope 61 is fixedly connected to the expansion portion 22 and the other end is fixedly connected to the first shell 11. In addition, the guide part 124 may include a guide shaft for guiding the movement of the flexible display 20, and a middle portion of the extension portion 22 may be partially bent around the guide shaft, so that the guide shaft may cooperate with the tension structure 60, and the guide shaft may guide the extension portion 22 to enable the extension portion 22 to be smoothly unfolded or retracted when the extension portion 22 moves.

In one example, the tension member 62 gradually releases the pull cord 61 during the process of moving the second shell 12 away from the first shell 11, thereby gradually releasing the expansion portion 22, the expansion portion 22 gradually expands out of the shell assembly 10 by the second shell 12, the distance of movement of the tension member 62 is the same as the movement stroke of the expansion portion 22, and in such a case, the expansion portion 22 expands outward relative to the first shell 11 at twice the speed of the tension member 62 relative to the first shell 11. Meanwhile, the tensioning member 62 can tension the pulling rope 61 during the process of gradually expanding the expansion part 22 out of the case assembly 10, thereby tensioning the flexible display screen 20.

In another example, the tension member 62 moves along with the second shell 12 during the process that the second shell 12 is relatively close to the first shell 11, one end of the pulling rope 61 is fixedly connected with the expansion part 22, the other end of the pulling rope 61 is fixedly connected with the first shell 11, the second shell 12 gradually releases the expansion part 22, the tension member 62 drives the pulling rope 61 to move towards the side where the first shell 11 is located so as to drive the expansion part 22 to gradually retract into the shell assembly 10, in such a process, the moving distance of the tension member 62 and the moving stroke of the expansion part 22 relative to the tension member 62 are the same, and in such a case, the expansion part 22 expands outwards relative to the first shell 11 at a speed twice as the speed that of the tension member 62 relative to the first shell 11. Meanwhile, the tensioning member 62 can tension the pull rope 61 during the process of retracting and extending the extension portion 22 to the housing assembly 10, thereby tensioning the flexible display screen 20. It can be understood that, during the assembly process of the electronic device 100, one end of the pull rope 61 can be fixedly connected to the first shell 11 after being sequentially wound around the tensioning member 62 and the pull rope 61, and during the installation process, it is required to ensure that the flexible display screen 20 is in a tensioned state, so that, due to the existence of the tensioning structure 60, the tensioning structure 60 can tension the flexible display screen 20 no matter how the second shell 12 moves.

Referring to fig. 6 and 13, in some embodiments, the tension member 62 includes a pulley 621, the pulley 621 is rotatably disposed on the second housing 12, and an intermediate portion of the pull cord 61 is wound around the pulley 621.

In this manner, the pulley 621 is rotatably provided on the second housing 12, and the pull rope 61 may be wound around the pulley 621 when the flexible display screen 20 is retracted to pull the flexible display screen 20 taut, thereby enabling the flexible display screen 20 to be smoothly extended and retracted.

Specifically, in the embodiment of the present application, the pulley 621 may be screw-rotatably provided on the second case 12 by a bolt, and the intermediate portion of the rope 61 is wound around the pulley 621. Thus, when the second shell 12 drives the expansion part 22 and the pulling rope 61 to move, the pulley 621 rolls correspondingly, rolling friction exists between the two, friction force is small, and compared with a mode of directly fixing the tensioning member 62 on the second shell 12, rotation can prevent the pulling rope 61 from being abraded greatly or even clamping the pulling rope 61 due to overlarge friction force between the pulling rope 61 and the tensioning member 62.

Of course, it is understood that in some embodiments, the tension member 62 may be directly fixed to the first shell 11, and it is only necessary to make the surface of the tension member 62 smooth without generating a large friction force with the pull rope 61 during the manufacturing process.

Furthermore, it is understood that in some embodiments, the tensioning structure 60 may also be a reel rotatably disposed on the first housing 11, one end of the extension portion 22 may be wound on the reel, and the reel may wind or release the extension portion 22, so that the flexible display screen 20 may be tensioned by the reel as well.

In the present embodiment, the movement of the pulling rope 61 and the tensioning member 62 is performed in cooperation with the motor 31 and the synchronizing shaft 32, that is, the motor 31 drives the synchronizing shaft 32 to rotate, and during the synchronizing shaft 32 drives the second shell 12 to move relative to the first shell 11 through the gear and the rack, the tensioning member 62 and the tensioning member are also moved synchronously to realize the cooperative movement of the flexible display screen 20 and the shell assembly 10. In addition, in the embodiment of the present application, the pulley 621 may be placed horizontally or vertically, or the axis of the pulley 621 may be designed to be parallel to the axis of the synchronizing shaft 32, or the axis of the pulley 621 may be designed to be perpendicular to the axis of the synchronizing shaft 32, and the specific placement manner of the pulley 621 is not limited herein, so as to meet various design requirements.
