Therefore, the limiting structure 31 in the supporting component 30 is matched with the limiting sliding groove 121 to limit the extension part 22 to move in the direction perpendicular to the flat part 21, so that the flatness of the flexible display screen 20 is ensured, and meanwhile, the limiting structure 31 slides in the limiting sliding groove 121 to ensure the stability of the movement of the flexible display screen 20 and the shell.

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, the configuration of the electronic device 100 is located when the first housing 11 and the second housing 12 are close to each other and move to the 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 20 to gradually expand to the outside of the housing assembly 10 (as shown in fig. 2), that is, the configuration of the electronic device 100 is when the first shell 11 and the second shell 12 move away from each other and move to the limit position, in the second configuration, the expansion portion 22 of the flexible display 20 at least partially expands to the outside of the housing assembly 10 to form the display portion of the electronic device 100 together with the flat portion 21, and the display area of the electronic device 100 is larger than that of the first configuration, so as to provide a better display effect for a user.

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

In the embodiment of the present application, the fact that the extension portion 22 can be hidden in the housing assembly 10 means that the extension portion 22 can be housed in the internal space of the housing assembly 10 and is not exposed, or the fact that the extension portion 22 can be hidden on the back surface of the housing 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 housing 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 can be disposed inside the housing assembly 10, belonging to a hidden structure. Referring to fig. 1, 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. When the second housing 12 moves away from the first housing 11, the flexible display 20 can be moved, so 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.

Further, when the electronic device 100 is configured to change its configuration, the supporting component 30 is connected to the extension portion 22 and functions to support the extension portion 22, so that the extension portion 22 is more flat, and the supporting component 30 can move together with the extension portion 22 to ensure that the supporting function is performed in both configurations of the electronic device 100. Meanwhile, please refer to fig. 7 and 8, when the electronic device 100 is in a form change, the limiting structure 31 of the supporting assembly 30 can slide in the limiting sliding groove 121, and the limiting structure 31 and the limiting sliding groove 121 cooperate to effectively limit the movement of the limiting structure 31 in the direction perpendicular to the flat portion 21, so as to stabilize the movement of the flexible display screen 20.

In addition, it is understood that the electronic device 100 may include other configurations besides the two extreme configurations, that is, the second housing 12 is not fully unfolded relative to the first housing 11, the second housing 12 may be moved to any position relative to the first housing 11 and stopped, and only a portion of the extension portion 22 is exposed outside the housing assembly 10 for display together with the flat portion 21. Thus, the display area of the electronic device 100 may vary according to the habit of the user, for example, the user may expose the extension 22 completely, or may expose ten percent, or twenty percent, of the extension 22, or other percentages of the extension 22, which is not limited herein.

In some embodiments, the first casing 11 in the electronic device 100 may serve as a main supporting structure of the electronic device 100, and the first casing 11 may accommodate therein components such as a camera, a speaker, a circuit board, and a battery. 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.

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. 9 and 10, in some embodiments, the second housing 12 includes a guide shaft portion 122 and a first guide rod 123, the guide shaft portion 122 is rotatably connected to the first guide rod 123, the support member 30 and the extension portion 22 are wound around the guide shaft portion 122, the first guide rod 123 is slidably connected to the first housing 11, the first guide rod 123 is used for guiding the sliding of the second housing 12 and the first housing 11, and a limit sliding groove 121 is formed on the first guide rod 123.

Thus, the guiding shaft portion 122 may be disposed at an end of the second housing 12 away from the first housing 11 to assist the movement of the extension portion 22 of the flexible display screen 20, and meanwhile, the limiting structure 31 may be engaged with the limiting sliding groove 121 on the first guiding rod 123 and slide in the limiting sliding groove 121 to fix the extension portion 22 in a direction perpendicular to the flat portion 21, so as to ensure that the extension portion 22 can stably drive the extension portion 22 to at least partially unfold into the housing assembly 10 or retract into the housing assembly 10, and ensure that the movement is smooth.

Specifically, when the form of the electronic device 100 is changed, the supporting assembly 30 and the extending portion 22 can move around the guiding shaft portion 122, and meanwhile, the limiting structure 31 can be engaged with the limiting sliding groove 121 on the first guiding rod 123 and slide in the limiting sliding groove 121 to fix the extending portion 22 in a direction perpendicular to the flat portion 21, so that the limiting of the housing assembly 10 relative to the flexible display screen 20 is achieved, and the stability of the movement of the flexible display screen 20 is ensured.

In some embodiments, notches 1221 may be spaced at both ends of the guide shaft portion 122, and the support member 30 may include spaced apart engagement teeth 1222, such that upon rotation of the second housing 12 relative to the first housing 11, the engagement teeth 1222 may engage the notches 1221 to assist in movement of the expansion portion 22. It will be appreciated that in such an embodiment, the guide shaft portion 122 may rotate relative to the second housing 12, that is, the guide shaft portion 122 may be rotatably disposed on the second housing 12, and when the second housing 12 moves relative to the first housing 11, the guide shaft portion 122 may rotate in cooperation to enable the engagement teeth 1222 to extend into the gap 1221 to assist the flexible display 20 to move smoothly.

Further, referring to fig. 9 and 10, in some embodiments, the limiting sliding groove 121 includes a first sliding groove 1211 and a second sliding groove 1212 formed on opposite sides of the first guiding rod 123, when the expansion portion 22 is fully retracted in the housing assembly 10, the limiting structure 31 is engaged with the second sliding groove 1212, and during the process that the expansion portion 22 is at least partially exposed from the housing assembly 10, the limiting structure 31 gradually slides from the second sliding groove 1212 into the first sliding groove 1211.

In this way, the limiting structure 31 can be engaged with the first sliding slot 1211 and slide in the first sliding slot 1211, so that when the expansion portion 22 is unfolded out of the housing assembly 10, the expansion portion 22 can be fixed in a direction perpendicular to the flat portion 21, and the flatness of the flexible display screen 20 is ensured. The limiting structure 31 can be engaged with the second sliding groove 1212 and slide in the second sliding groove 1212, so that when the extension portion 22 is retracted into the housing assembly 10, the extension portion 22 can be fixed in a direction perpendicular to the flat portion 21, thereby ensuring that the extension portion 22 is retracted smoothly, and preventing the flexible display screen 20 from arching and folding in the housing assembly 10.

Specifically, when the electronic device 100 is in the first configuration, the extension portion 22 is completely retracted in the housing assembly 10, and the limiting structure 31 cooperates with the second sliding groove 1212 to limit the position of the flexible display screen 20, so as to prevent the flexible display screen 20 from affecting other components inside the housing assembly 10. When the electronic device 100 is in the second configuration, the extension portion 22 may be exposed outside the housing assembly 10, and the limiting structure cooperates with the first sliding slot 1211 to prevent the extension portion 22 from protruding or being uneven relative to the flat portion 21, so as to ensure the display effect of the flexible display screen 20.

It will be appreciated that the support member 30 and the extension portion 22 may move about the guide shaft portion 122, i.e., different portions of the support member 30 may flex relative to one another. During the form change of the electronic device 100, the position-limiting structure 31 may slide in the first sliding slot 1211 and the second sliding slot 1212 successively. For example, when the electronic device 100 is converted from the first form to the second form, the position-limiting structure 31 may gradually slide into the first sliding groove 1211 from the second sliding groove 1212; when the electronic device 100 is converted from the second configuration to the first configuration, the position-limiting structure 31 can gradually slide into the second sliding groove 1212 from the first sliding groove 1211. In addition, when the electronic device 100 is in the first configuration, at least a portion of the limiting structure 31 may be kept to extend into the first sliding slot 1211; when the electronic device 100 is in the second configuration, at least a portion of the limiting structure 31 may be remained to extend into the second sliding groove 1212. Therefore, when the form of the electronic device 100 is changed, the limiting structure 31 can slide back and forth between the first sliding slot 1211 and the second sliding slot 1212, and the movement is smooth.

Referring to fig. 10, in some embodiments, the electronic device 100 includes a second guiding rod 40, a first tensioning member 50, a second tensioning member 60, and a connecting member 80, wherein the second guiding rod 40 and the first guiding rod 123 are oppositely disposed at an interval, the first tensioning member 50 and the second tensioning member 60 are disposed at an interval between the first guiding rod 123 and the second guiding rod 40 and are connected to the first guiding rod 123 and the second guiding rod 40, the connecting member 80 is sequentially wound around the first tensioning member 50 and the second tensioning member 60, a portion of the connecting member 80 located at one side of the first tensioning member 50 and the second tensioning member 60 is fixedly connected to the first housing 11, and a portion of the connecting member 80 located at the other side of the first tensioning member 50 and the second tensioning member 60 is fixedly connected to the expansion portion 22.

In this way, the connecting member 80 can connect the first shell 11 and the expansion portion 22 at the same time, when the second shell 12 moves relative to the first shell 11, the connecting member 80 can drive the expansion portion 22 to move in cooperation with the first shell 11, when the first shell 11 and the second shell 12 are gradually far away from each other, the expansion portion 22 can be gradually exposed, and when the first shell 11 and the second shell 12 are gradually close to each other, the expansion portion 22 can be gradually retracted. The connecting member 80 is sequentially wound on the first tensioning member 50 and the second tensioning member 60, and the first tensioning member 50 and the second tensioning member 60 can assist the connecting member 80 to move, so that the friction force in the moving process of the connecting member 80 is prevented from influencing the movement of the connecting member 80.

Specifically, the first and second guide bars 123 and 40 are provided at intervals on the first housing 11, and the first and

second tightening members

50 and 60 are provided between the first and second guide bars 123 and 40 at positions of both end portions of the first and second guide bars 123 and 40, so that the connection member 80 can be bridged between the first and

second tightening members

50 and 60, that is, the connection member 80 can be sequentially wound around the first and

second tightening members

50 and 60. At this time, one side of the connecting member 80 opposite to the first tensioning member 50 and the second tensioning member 60 is used for fixedly connecting the first housing 11, and the other side is used for fixedly connecting the expansion part 22. Thus, when the second housing 12 moves relative to the first housing 11, the connecting member 80 can slide around the first tensioning member 50 and the second tensioning member 60, so that the extension portion 22 can move synchronously, thereby ensuring the coordination of the movement of the flexible display screen 20 and the housing assembly 10.

Referring to fig. 10, in some embodiments, the first tensioning member 50 and the second tensioning member 60 are rotatably connected to the first guide rod 123 and the second guide rod 40.

Thus, the first tensioning member 50 and the second tensioning member 60 can rotate relative to the first guiding rod 123 and the second guiding rod 40, and the connecting member 80 can drive the two tensioning members to rotate relative to the first guiding rod 123 and the second guiding rod 40 when being wound on the two tensioning members and moved, so that rolling friction is generated between the first tensioning member 50, the second tensioning member 60 and the connecting member 80, and the influence of too much friction on the movement of the housing assembly 10 and the flexible display screen 20 can be avoided.

Specifically, the first tensioning member 50 and the second tensioning member 60 may be pulleys rotatably provided at both ends of the first guide rod 123 and the second guide rod 40, and the link 80 may be bridged on the two pulleys. The length direction of the first guiding rod 123 and the second guiding rod 40 is the moving direction of the second housing 12 relative to the first housing 11, so that when the electronic device 100 changes its configuration, the connecting member 80 can slide back and forth along the length direction of the first guiding rod 123 and the second guiding rod 40, and the first tensioning member 50, the second tensioning member 60 and the connecting member 80 have rolling friction therebetween, so as to prevent the friction between the first tensioning member 50, the second tensioning member 60 and the connecting member 80 from affecting the movement of the housing assembly 10 and the flexible display 20.

Further, referring to fig. 10 and 11, in some embodiments, the connecting element 80 includes two pulling ropes 83, the two pulling ropes 83 are wound around the first tensioning element 50 and the second tensioning element 60, the electronic device 100 further includes a first connecting seat 81 and a second connecting seat 82, the first connecting seat 81 is fixedly connected to the first shell 11 and the pulling ropes 83, the second connecting seat 82 is fixedly connected to the expansion portion 22 and the pulling ropes 83, a first limiting protrusion 811 is formed on the first connecting seat 81, a second limiting protrusion 821 is formed on the second connecting seat 82, the connecting element 80 further includes a first connecting section 84 and a second connecting section 85, the first connecting section 84 is wound around the first limiting protrusion 811, two ends of the first connecting section are respectively connected to the two pulling ropes 83, and the second connecting section 85 is wound around the second limiting protrusion 821, and two ends of the second connecting section are respectively connected to the two pulling ropes 83.

In this manner, the two pulling ropes 83 can be wound around the first and second limiting

protrusions

811 and 821 through the first and second connecting sections 84 and 85, respectively, to fixedly connect the first connecting seat 81 and the second connecting seat 82, the first connecting seat 81 is fixedly connected to the first shell 11, and the second connecting seat 82 is fixedly connected to the expansion part 22, so that the expansion part 22 and the first shell 11 can be connected together through the pulling ropes 83 and the two connecting seats, so that the expansion part 22 and the first shell 11 can move in cooperation.
