[0028] To address the existing technical problems, embodiments of this application provide an electronic device 100 and an electronic device in general. For a better understanding of this application, the following describes... Figures 1 to 8 The electronic device 100 according to the embodiments of this application will be described in detail.

[0029] The electronic devices provided in the embodiments of this application will be described below.

[0030] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the electronic device in the extended state according to an embodiment of this application; Figure 2 This is a schematic diagram of the retracted state of the electronic device according to an embodiment of this application; Figure 3 yes Figure 2 A partially enlarged schematic diagram of the electronic device according to an embodiment of this application.

[0031] like Figures 1 to 3 As shown, this application provides an electronic device 100, including a first housing 10, a second housing 20, and a drive assembly 30. At least a portion of the second housing 20 is sleeved outside the first housing 10, and the second housing and the first housing are movable relative to each other. The drive assembly 30 is disposed in the first housing 10, and the drive assembly 30 includes a movable rod 31 and a rotating shaft 32. The rotating shaft 32 is disposed in the first housing 10 and is rotatable relative to the first housing 10. The rotating shaft 32 is hollow. The first end of the movable rod 31 is disposed inside the rotating shaft 32 and is movably connected to the rotating shaft 32. The second end of the movable rod 31 is connected to the second housing 20. When the rotating shaft 32 rotates, the movable rod 31 moves along the rotating shaft 32 and extends and retracts relative to the rotating shaft 32, thereby driving the first housing 10 and the second housing 20 to move relative to each other.

[0032] In this embodiment, the first housing 10 and the second housing 20 are peripheral components of the electronic device 100, and the first housing 10 and the second housing 20 are basic mounting components of the electronic device 100, which can provide a mounting base for components such as the drive assembly 30. The first housing 10 and the second housing 20 are movable relative to each other to realize the telescopic movement of the electronic device 100.

[0033] Optionally, the electronic device 100 component also includes a flexible screen, which can serve as a display component of the electronic device 100 to provide some information from the electronic device 100 to the user. The user can also operate the flexible screen to input relevant information.

[0034] For example, one end of the flexible screen is connected to the second housing 20, and the other end of the flexible screen is movably disposed within the first housing 10, so that at least the first housing 10 can move the flexible screen. During use, when the second housing 20 moves away from the first housing 10, the second housing 20 causes the flexible screen hidden within the electronic device 100 to at least partially unfold, increasing the display area exposed to the external environment and thus providing a better visual experience for the electronic device 100. When the second housing 20 moves closer to the first housing 10, a portion of the exposed area of ​​the flexible screen is transferred to the non-display side, which can be understood as reducing the display area and thus reducing the size of the electronic device 100, making it easier to carry.

[0035] In this embodiment, the driving component 30 serves as the driving mechanism for the flexible screen, driving the first housing 10 and the second housing 20 to move relative to each other, thereby enabling the flexible screen to extend and retract.

[0036] In this embodiment, the first end of the movable rod 31 is disposed within and movably connected to the rotating shaft 32, and the second end of the movable rod 31 is connected to the second housing 20. The first end of the movable rod 31 moves within the rotating shaft 32. During the movement of the first end of the movable rod 31 towards the second housing 20, a larger portion of the movable rod 31 extends beyond the rotating shaft 32, resulting in an extended state. The second end of the movable rod 31 then drives the second housing 20 and the first housing 10 to move in a direction away from each other. During the movement of the first end of the movable rod 31 away from the second housing 20, a larger portion of the movable rod 31 retracts into the base 33, resulting in a retracted state. The second end of the movable rod 31 then drives the second housing 20 and the first housing 10 to move in a direction closer to each other.

[0037] In this embodiment, the rotating shaft 32 is disposed on the first housing 10 and can rotate relative to the first housing 10. The rotating shaft 32 has a hollow structure, and the first end of the movable rod 31 is disposed inside the rotating shaft 32. During the rotation of the rotating shaft 32, the rotating shaft 32 can drive the movable rod 31 to move along the rotating shaft 32, thereby realizing the extension and retraction of the movable rod 31 relative to the base 33, so as to drive the first housing 10 and the second housing 20 to move relative to each other.

[0038] For example, the inner wall of the rotating shaft 32 is provided with a wave groove extending circumferentially along the rotating shaft 32. The first end of the movable rod 31 extends into the wave groove and slides in the wave groove. As the rotating shaft 32 rotates, the movable rod 31 reciprocates along the rotating shaft 32, thereby realizing the extension and retraction of the movable rod 31 relative to the base 33.

[0039] For example, the inner wall surface of the rotating shaft 32 is provided with a threaded groove 321 extending axially along the rotating shaft 32. The first end of the movable rod 31 is threadedly engaged with the threaded groove 321. As the rotating shaft 32 rotates clockwise, the first end of the movable rod 31 rotates with the rotation of the rotating shaft 32 and moves towards the second housing 20 along the rotating shaft 32. The movable rod 31 is in an extended state. The second end of the movable rod 31 drives the second housing 20 and the first housing 10 to move away from each other in a direction. As the rotating shaft 32 rotates counterclockwise, the first end of the movable rod 31 rotates with the rotation of the rotating shaft 32 and moves away from the second housing 20 along the rotating shaft 32. The movable rod 31 is in a retracted state. The second end of the movable rod 31 drives the second housing 20 and the first housing 10 to move towards each other in a direction.

[0040] The electronic device 100 provided in this application embodiment uses a rotating shaft 32 to rotate, causing the movable rod 31 to extend or retract relative to the rotating shaft 32, thereby achieving relative movement between the first housing 10 and the second housing 20. This provides a novel flexible screen driving method with a simple structure, high assembly efficiency, high reliability, and low cost. Moreover, when the flexible screen is retracted, the movable rod 31 partially retracts into the rotating shaft 32, occupying less internal space in the electronic device 100, thereby improving motherboard utilization and battery capacity, which is beneficial for meeting the high performance and long battery life requirements of the electronic device 100.

[0041] See also Figure 4 and Figure 5 , Figure 4 This is a partial structural schematic diagram of an electronic device according to an embodiment of this application; Figure 5 This is a partial cross-sectional schematic diagram of an electronic device according to an embodiment of this application.

[0042] In some alternative embodiments, as shown in Figure 2, Figure 4 and Figure 5 As shown, the electronic device 100 also includes a base 33 disposed on the first housing 10, and a rotating shaft 32 rotatably connected to the base 33. The drive assembly 30 also includes a guide 34, which is fixedly connected to the base 33. The rotating shaft 32 is sleeved on the guide 34 and can rotate relative to the guide 34. The guide 34 is hollow, and the first end of the movable rod 31 is disposed inside the guide 34 and movably connected to the guide 34. When the rotating shaft 32 rotates, the movable rod 31 moves along the guide 34 and extends or retracts.

[0043] In this embodiment, the base 33 serves as the mounting base for the movable rod 31 and the rotating shaft 32, and provides support for them. Specifically, the base 33 has a through hole through which the movable rod 31 passes and can reciprocate. The shape, size, and specific position of the base 33 within the first housing 10 can be customized according to actual needs. For example, the shape of the base 33 can be selected from a rectangular frame structure, a trapezoidal frame structure, a groove structure, or other similar structures.

[0044] In this embodiment, the guide member 34 is fixedly connected to the base 33, and the rotating shaft 32 is sleeved on the guide member 34, and the rotating shaft 32 can rotate relative to the guide member 34, while the guide member 34 is fixedly connected to the base 33 and does not rotate. The guide member 34 is hollow, and the first end of the movable rod 31 is disposed inside the guide member 34 and can move within the guide member 34. When the rotating shaft 32 rotates, the movable rod 31 moves along the guide member 34. At this time, the movable rod 31 can slide or rotate within the guide member 34, as long as the movable rod 31 can extend or retract relative to the base 33.

[0045] Optionally, the guide member 34 is one of a hollow guide rod, a hollow guide shaft, or a hollow guide groove.

[0046] In these optional embodiments, by providing a guide 34, the guide 34 can not only plan the movement path of the movable rod 31, but also provide guidance for the movement of the movable rod 31. Moreover, by limiting the movement of the movable rod 31, the probability of the movable rod 31 slipping out of the rotating shaft 32 can be reduced. In addition, the first end of the movable rod 31 is disposed in the guide 34, and the guide 34 is disposed in the rotating shaft 32. This arrangement further reduces the space occupied by the above-mentioned components within the electronic device 100.

[0047] See also Figure 6 , Figure 6 This is a structural diagram of the rotating shaft of an electronic device according to an embodiment of this application.

[0048] In some alternative embodiments, such as Figure 5 and Figure 6 As shown, the inner wall of the rotating shaft 32 is provided with a threaded groove 321 that extends spirally in the circumference of the rotating shaft 32. The guide member 34 is provided with a sliding groove 341 along the extension and retraction direction of the movable rod 31. The first end of the movable rod 31 is provided with a protrusion 311, which is connected to the threaded groove 321 through the sliding groove 341. When the rotating shaft 32 rotates, the threaded groove 321 drives the protrusion 311 to slide along the sliding groove 341, thereby extending and retracting the movable rod 31.

[0049] In this embodiment, the inner wall of the rotating shaft 32 is provided with a threaded groove 321 that extends spirally along the circumference of the rotating shaft 32. The threaded groove 321 can extend to a portion of the inner wall of the rotating shaft 32 along the circumference of the rotating shaft 32, or it can extend to the entire inner wall of the rotating shaft 32 along the circumference of the rotating shaft 32. The guide member 34 is provided with a sliding groove 341 along the extension and retraction direction of the movable rod 31. The first end of the movable rod 31 is provided with a protrusion 311, which protrudes from the sliding groove 341 and is connected to the threaded groove 321 through the sliding groove 341. When the rotating shaft 32 rotates, based on the combined action of the sliding groove 341 and the threaded groove 321, the protrusion 311 also slides along the sliding groove 341 in the extension and retraction direction of the movable rod 31 during the sliding process of the threaded groove 321.

[0050] For example, when the shaft 32 rotates clockwise, the protrusion 311 engages with the threaded groove 321 to drive the protrusion 311 to slide along the slide groove 341 towards the second housing 20, thereby extending the movable rod 31. The second end of the movable rod 31 abuts against the second housing 20, allowing the first housing 10 to move relative to the second housing 20 in a direction away from the second housing 20. When the shaft 32 rotates counterclockwise, the protrusion 311 engages with the threaded groove 321 to drive the protrusion 311 to slide along the slide groove 341 towards the second housing 20, thereby retracting the movable rod 31. The second end of the movable rod 31 abuts against the second housing 20, allowing the first housing 10 to move relative to the second housing 20 in a direction towards the second housing 20.

[0051] In this embodiment, the first end of the movable rod 31 is provided with one or more protrusions 311. When the first end of the movable rod 31 is provided with one protrusion 311, one protrusion 311 is connected to the threaded groove 321 through a sliding groove 341. When the first end of the movable rod 31 is provided with multiple protrusions 311, and the guide member 34 is provided with a sliding groove 341, the multiple protrusions 311 are spaced apart along the axial direction of the guide member 34, and the multiple protrusions 311 are connected to the threaded groove 321 through a sliding groove 341. When the guide member 34 is provided with multiple sliding grooves 341, the multiple protrusions 311 are spaced apart on the guide member 34, and at least one protrusion 311 is connected to the threaded groove 321 through its corresponding sliding groove 341.

[0052] In these optional embodiments, this configuration ensures that the movable rod 31 moves linearly along the guide 34 and does not rotate with the pivot 32, thereby improving the movement stability of the movable rod 31 and making the connection between the movable rod 31 and the second housing 20 more stable. Furthermore, the absence of rotation of the movable rod 31 reduces contact friction with other structural components of the electronic device 100, such as the second housing 20, thus improving the sensitivity and service life of the movable rod 31.

[0053] In some alternative embodiments, the guide member 34 has two grooves 341, which are arranged opposite to each other. The movable rod 31 has two protrusions 311, each of which is connected to the threaded groove 321 through its corresponding groove 341.

[0054] In these optional embodiments, the guide member 34 has two grooves 341, and the movable rod 31 has two protrusions 311. Each protrusion 311 is connected to the threaded groove 321 through its corresponding groove 341. During the rotation of the rotating shaft 32, the two protrusions 311 slide in their respective corresponding grooves 341. The two protrusions 311 drive the movable rod 31 to move along the guide member 34, so that the movable rod 31 is subjected to uniform force and the sliding stability of the movable rod 31 is improved.

[0055] See also Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of the guide and movable rod of the electronic device according to an embodiment of this application; Figure 8 This is a cross-sectional schematic diagram of the guide and movable rod of the electronic device according to an embodiment of this application.

[0056] In some alternative embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, the guide member 34 has a first limiting port 342 and a second limiting port 343 at both ends, and the first limiting port 342 and the second limiting port 343 are respectively fixedly connected to the base 33.

[0057] For example, the base 33 includes a bottom, a first support portion, a second support portion, and a pressure block. The first support portion and the second support portion are located at opposite ends of the bottom. The pressure block is disposed on the second support portion. Both the end of the pressure block and the end of the second support portion are provided with through grooves, and the two through grooves enclose a through hole. The guide member 34 is provided with a first limiting port 342 and a second limiting port 343 at both ends. The first limiting port 342 cooperates with the stop of the first support portion, and the second limiting port 343 extends into the through hole and is fixedly connected to the through hole. With this configuration, during the assembly of the electronic device 100, the first end of the movable rod 31 can be placed inside the hollow structure of the guide member 34, the rotating shaft 32 can be sleeved on the guide member 34, the first limiting port 342 of the guide member 34 can be fixed to the first support part, the second limiting port 343 of the guide member 34 can be fixed in the through groove of the second support part, and the pressure block can be pressed on the second support part. The through groove of the pressure block cooperates with the second limiting port 343, so that the second limiting port 343 extends into the through hole and is fixedly connected to the through hole, simplifying the assembly of the electronic device 100.

[0058] In these alternative embodiments, by providing a first limiting port 342 and a second limiting port 343 at both ends of the guide member 34, the guide member 34 is restricted from rotating with the rotating shaft 32 by the first limiting port 342 and the second limiting port 343.

[0059] In some alternative embodiments, such as Figure 5 As shown, the electronic device 100 also includes a bearing assembly 40, which is disposed between the guide member 34 and the rotating shaft 32. The rotating shaft 32 is connected to the guide member 34 through the bearing assembly 40, and the bearing assembly 40 can rotate relative to the guide member 34 with the rotating shaft 32.

[0060] In this embodiment of the application, the bearing assembly 40 includes one or more bearings, which are sleeved on the rotating shaft 32, and the bearing assembly 40 can rotate with the rotating shaft 32 relative to the guide member 34. When the bearing assembly 40 includes multiple bearings, the multiple bearings are spaced apart along the axial direction of the guide member 34.

[0061] In these alternative embodiments, the bearing assembly 40 is used to support the rotation of the shaft 32. The bearing assembly 40 is provided between the guide 34 and the shaft 32 to reduce the coefficient of friction of the shaft 32 during movement, so as to ensure the normal rotation of the shaft 32.

[0062] In some alternative embodiments, the bearing assembly 40 includes a first bearing 41 and a second bearing 42, which are sleeved on both ends of the guide member 34 and located between the first limiting port 342 and the second limiting port 343.

[0063] In this embodiment, the electronic device 100 further includes a washer fitted onto the guide member 34 and positioned between the base 33 and the second bearing 42. This arrangement reduces the frictional resistance generated by the contact between the base 33 and the second bearing 42.

[0064] In these alternative embodiments, the bearing assembly 40 includes a first bearing 41 and a second bearing 42, which are sleeved on both ends of the guide member 34 to support the rotating shaft 32 at both ends of the guide member 34, thereby further improving the connection stability between the guide member 34 and the rotating shaft 32.

[0065] In some optional embodiments, the second end of the movable rod 31 is provided with a limiting groove 312, which is engaged with the second housing 20.

[0066] For example, the second end of the movable rod 31 is provided with a limiting groove 312, which extends around the circumference of the movable rod 31.

[0067] In these optional embodiments, the limiting groove 312 of the movable rod 31 engages with the second housing 20 to fix the movable rod 31 and the second housing 20, and to simplify the assembly process of the limiting groove 312 and the second housing 20. At the same time, it can also increase the connection area between the limiting groove 312 and the second housing 20, increase the stability of the contact, and improve the connection strength.

[0068] In some alternative embodiments, the drive assembly 30 further includes a drive element 50, which is movably connected to the rotating shaft 32 and can drive the rotating shaft 32 to rotate.

[0069] Optionally, the drive unit 50 is a drive motor.

[0070] In some alternative embodiments, such as Figure 5 and Figure 6As shown, the electronic device 100 also includes a first gear 60, which is connected to the drive member 50. A second gear 70 is sleeved on the rotating shaft 32 and fixedly connected to the rotating shaft 32. The first gear 60 and the second gear 70 mesh, and the drive member 50 drives the first gear 60 and the second gear 70 to rotate the rotating shaft 32.

[0071] In this embodiment of the application, the electronic device 100 further includes a first gear 60 and a second gear 70. The first gear 60 is connected to the driving member 50, and the second gear 70 is sleeved on the rotating shaft 32 and fixedly connected to the rotating shaft 32. The first gear 60 and the second gear 70 mesh, and the driving member 50 drives the first gear 60 and the second gear 70 to rotate, so that the second gear 70 drives the rotating shaft 32 to rotate, thereby realizing the extension and retraction of the movable rod 31 relative to the base 33.

[0072] For example, the first gear 60 and the second gear 70 are arranged side by side. When the driving component 50 receives a first command, the driving component 50 drives the first gear 60 to rotate clockwise, thereby causing the second gear 70 to rotate clockwise. The second gear 70 drives the shaft 32 to rotate clockwise, thereby causing the movable rod 31 to extend relative to the base 33. When the driving component receives a second command, the driving component 50 drives the first gear 60 to rotate counterclockwise, thereby causing the second gear 70 to rotate counterclockwise. The second gear 70 drives the shaft 32 to rotate counterclockwise, thereby causing the movable rod 31 to retract relative to the base 33.

[0073] In these alternative embodiments, the drive member 50 drives the rotating shaft 32 to rotate via the first gear 60 and the second gear 70. The first gear 60 and the second gear 70 play a transmission role between the drive member 50 and the rotating shaft 32. The gear transmission has high working efficiency and long service life.

[0074] In some optional embodiments, the outer surface of the movable rod 31 is threaded, and the movable rod 31 is rotatably connected to the second housing 20; the end of the rotating shaft 32 near the through hole is at least partially threaded to the movable rod 31, wherein, when the rotating shaft 32 rotates, the rotating shaft 32 drives the movable rod 31 to rotate and the movable rod 31 moves along the guide member 34 to cause the movable rod 31 to extend or retract.

[0075] In these alternative embodiments, the threads on the outer surface of the movable rod 31 are threadedly connected to one end of the rotating shaft 32 near the through hole. When the rotating shaft 32 rotates, the first end of the movable rod 31 can be screwed out or screwed into the guide member 34 through the threaded engagement with one end of the rotating shaft 32, thereby allowing the movable rod 31 to extend and retract relative to the base 33 along the guide member 34. This arrangement simplifies the structure of the rotating shaft 32 and facilitates manufacturing.
