Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0049] In the description of the present application, it should be understood that the terms "first" and "second" may explicitly or implicitly include one or more of the features.

[0050] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] like Figure 1 and Figure 2 As shown, the electronic device according to the embodiment of the present application includes: a housing and a driving component 3.

[0052] The housing comprises a first housing 1 and a second housing 2 which are movable relative to each other. The first housing 1 and the second housing 2 are slidably connected, that is, the second housing 2 can slide relative to the first housing 1 .

[0053] The driving assembly 3 includes a working medium 33 , a movable member 35 , a first cylinder body 32 and a second cylinder body 34 .

[0054] Among them, the working medium 33 can be hydraulic oil, and the corresponding first cylinder body 32 and second cylinder body 34 can be hydraulic cylinders. Using hydraulic oil as a power transmission medium has the characteristics of stepless speed change and fast response, and can achieve more precise motion control. By selecting compressible fluid, when the electronic equipment is subjected to external impact, it can have certain buffering characteristics.

[0055] The first cylinder 32 is disposed in the first housing 1 , the second cylinder 34 is disposed in the second housing 2 , the first cylinder 32 and the second cylinder 34 are communicated, the working medium 33 is disposed in the first cylinder 32 and the second cylinder 34 , and the movable member 35 is slidably disposed in the first cylinder 32 .

[0056] In which, when the movable part 35 moves toward the direction approaching the second cylinder body 34, the working medium 33 flows from the first cylinder body 32 to the second cylinder body 34, which can cause the second shell 2 to move in the direction away from the first shell 1; when the movable part 35 moves in the direction away from the second cylinder body 34, the working medium 33 flows from the second cylinder body 34 to the first cylinder body 32, which can cause the second shell 2 to move in the direction approaching the first shell 1.

[0057] It should be noted that, in the initial state, before the movable part 35 moves relative to the first cylinder body 32, the working medium 33 is located in the first cylinder body 32, and when the movable part 35 moves toward the direction close to the second cylinder body 34, the working medium 33 flows from the first cylinder body 32 to the second cylinder body 34. Due to the incompressibility of the working medium 33, the second shell 2 can be moved in the direction away from the first shell 1; when the movable part 35 moves in the direction away from the second cylinder body 34, the working medium 33 flows from the second cylinder body 34 to the first cylinder body 32. At this time, the working medium 33 in the second cylinder body 34 all flows back to the first cylinder body 32, and the second shell 2 can be moved in the direction close to the first shell 1.

[0058] In the embodiment of the present application, when the movable member 35 moves toward the direction close to the second cylinder 34, the second housing 2 slides relative to the first housing 1 to move away from the first housing 1, which can expand the display part of the electronic device; or, when the movable member 35 moves toward the direction away from the second cylinder 34, the second housing 2 slides relative to the first housing 1 to move closer to the first housing 1, which can reduce the display part of the electronic device. In this way, when the movable member 35 moves relative to the first cylinder 32, the display part of the electronic device can be expanded or reduced, which can meet the use requirements in different scenarios.

[0059] In an optional embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the electronic device further includes a rotating shaft 6 , a first elastic connecting member 7 and a flexible display screen 5 .

[0060] The first elastic connecting member 7 may be a spring or other device with expansion and contraction capability, and its specific type is not specifically limited here.

[0061] The rotating shaft 6 is disposed in the second housing 2, and a gap is left between the rotating shaft 6 and the second housing 2. One end of the flexible display screen 5 is connected to the first housing 1, and the other end of the flexible display screen 5 is connected to the first housing 1 through the first elastic connector 7 after passing around the rotating shaft 6. In other words, the other end of the flexible display screen 5 can pass through the gap between the rotating shaft 6 and the second housing 2. One end of the first elastic connector 7 is connected to the first housing 1, and the other end of the first elastic connector 7 is connected to the other end of the flexible display screen 5.

[0062] In the embodiment of the present application, when the movable member 35 moves toward the direction close to the second cylinder 34, the second shell 2 slides relative to the first shell 1 to move away from the first shell 1, and the other end of the flexible display screen 5 moves toward the direction away from the first shell 1, thereby expanding the display portion of the flexible display screen 5, and the first elastic connector 7 is in an extended state at this time; or, when the movable member 35 moves toward the direction away from the second cylinder 34, the second shell 2 slides relative to the first shell 1 to move toward the first shell 1, and the other end of the flexible display screen 5 moves toward the direction close to the first shell 1, thereby reducing the display portion of the flexible display screen 5, and the first elastic connector 7 is in the original length state at this time. In this way, the setting of the driving component 3 can ensure the smoothness and reliability of the movement of the flexible display screen when the electronic device expands or reduces the display portion of the flexible display screen, and the setting of the first elastic connector 7 can make the flexible display screen less prone to wrinkles during the extension and recovery process.

[0063] It can be understood that when the first elastic connecting member 7 is in the original length state and the extended state, the flexible display screen 5 can be in a taut state.

[0064] In an optional embodiment, if Figure 1 and Figure 2 As shown, a protrusion is provided on one side of the first cylinder body 32 facing the second cylinder body 34, and a recess is provided on the second cylinder body 34. The protrusion is provided with a first opening, and at least a part of the protrusion is slidably disposed in the recess.

[0065] The movable part 35 can move from the first position to the second position relative to the first cylinder body 32, and the working medium 33 in the protrusion enters the recess through the first opening. At this time, the second shell 2 can slide relative to the first shell 1 to move away from the first shell 1, thereby expanding the display part of the flexible display screen 5.

[0066] The movable part 35 can move from the second position to the first position relative to the first cylinder body 32, and the working medium 33 in the recessed part enters the raised part through the first opening. At this time, the second shell 2 can slide relative to the first shell 1 to approach the first shell 1, thereby reducing the display part of the flexible display screen 5.

[0067] It should be noted that the raised portion is provided with a seal 4 near the first opening. The seal 4 may be a silicone plug. The provision of the seal 4 can prevent the working medium 33 in the recessed portion from leaking out.

[0068] In the embodiment of the present application, a hydraulic drive method is adopted. Compared with the existing gear meshing transmission mechanism, the movement is stable, too many mechanical transmission mechanisms are not required, the internal space of the electronic device is smaller, and the weight of the electronic device is lighter.

[0069] In an optional embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the driving assembly further includes a driving member 31 and a rotating member 39 . The driving member 31 drives the movable member 35 to move relative to the first cylinder body 32 . The rotating member 39 is rotatably disposed in the second cylinder body 34 , and the rotating member 39 is connected to the rotating shaft 6 .

[0070] Among them, when the movable part 35 moves toward the direction of the second cylinder body 34, the rotating part 39 rotates along the first direction, the rotating shaft 6 rotates synchronously therewith, and the second shell 2 can move in the direction away from the first shell 1. When the movable part 35 moves in the direction away from the second cylinder body 34, the rotating part 39 rotates along the second direction, the rotating shaft 6 rotates synchronously therewith, and the second shell 2 can move in the direction close to the first shell 1. The first direction and the second direction are opposite.

[0071] Among them, the movable part 35 is slidably arranged in the first cylinder body 32, and the driving part 31 is connected to the movable part 35; the first cylinder body 32 is provided with a first opening, and the second cylinder body 34 is provided with a second opening, and the first cylinder body 32 and the second cylinder body 34 are connected through the first opening and the second opening; the rotating part 39 is rotatably arranged in the second cylinder body 34, and the rotating part 39 is connected to the rotating shaft 6.

[0072] It should be noted that, driven by the driving member 31, the movable member 35 moves toward the second cylinder body 34, and the working medium 33 in the first cylinder body 32 enters the second cylinder body 34. The working medium 33 drives the rotating member 39 to rotate in a clockwise direction relative to the second cylinder body 34. When the rotating shaft 6 rotates in a clockwise direction relative to the second shell 2, the rotating shaft 6 can move from one end of the flexible display screen 5 to the other end of the flexible display screen 5 relative to the flexible display screen 5. At this time, the second shell 2 can slide relative to the first shell 1 to move away from the first shell 1, thereby expanding the display part of the flexible display screen 5.

[0073] Driven by the driving member 31, the movable member 35 moves in the direction away from the second cylinder body 34, the working medium 33 in the second cylinder body 34 enters the first cylinder body 32, and the rotating member 39 can rotate counterclockwise relative to the second cylinder body 34. When the rotating shaft 6 rotates counterclockwise relative to the second shell 2, the rotating shaft 6 can move from the other end of the flexible display screen 5 to one end of the flexible display screen 5 relative to the flexible display screen 5. At this time, the second shell 2 can slide relative to the first shell 1 to approach the first shell 1, thereby reducing the display part of the flexible display screen 5.

[0074] The driving member 31 may be disposed on the first housing 1 , or the driving member 31 may be disposed on the second housing 2 , or the driving member 31 may be disposed outside the housing.

[0075] That is to say, the driving member 31 only needs to be able to drive the movable member 35 to move relative to the first cylinder body 32 , and its specific arrangement position is not specifically limited herein.

[0076] The following is an explanation using the example of a driving member 31 disposed in the first shell 1. The driving member 31 includes a driving source 311, a cam 312 and a third elastic connecting member 37. The power output shaft of the driving source 311 is connected to the cam 312, the movable member 35 stops at the rim of the cam 312, one end of the third elastic connecting member 37 is connected to the movable member 35, and the other end of the third elastic connecting member 37 is connected to the first cylinder body 32.

[0077] Among them, the third elastic connecting member 37 can be a spring. In order to ensure the moving direction of the third elastic connecting member 37, the driving member 31 also includes a guide shaft, which is arranged on the first cylinder body 32, and the third elastic connecting member 37 is sleeved on the guide shaft. One end of the third elastic connecting member 37 is connected to the guide shaft, and the other end of the third elastic connecting member 37 is connected to the movable member 35.

[0078] Wherein, under the action of the cam 312, the movable member 35 can move from the first position to the second position relative to the first cylinder body 32. Under the action of the restoring force provided by the third elastic connecting member 37, the movable member 35 can move from the second position to the first position relative to the first cylinder body 32.

[0079] In an optional embodiment, the movable member 35 is a magnetic member, and when the driving member 31 is energized, the driving member 31 can drive the movable member 35 to move relative to the first cylinder body 32 .

[0080] For example, when there is a magnetic repulsion between the driving member 31 and the movable member 35 , the movable member 35 can move toward the direction where the second cylinder 34 is located. When there is a magnetic attraction between the driving member 31 and the movable member 35 , the movable member 35 moves in a direction away from the second cylinder 34 .

[0081] The driving member 31 may be arranged outside the housing.

[0082] In an optional embodiment, the electronic device further includes a transmission assembly 8 , and the rotating member 39 is connected to the rotating shaft 6 via the transmission assembly 8 .

[0083] It should be noted that, in order to ensure the smoothness of power transmission, the rotating member 39 is connected to the rotating shaft 6 through the transmission assembly 8 .

[0084] In an optional embodiment, the transmission assembly 8 includes a transmission shaft 81 , a first gear 82 and a second gear 83 .

[0085] Among them, the transmission shaft 81 is set through the rotating member 39, the central axis of the transmission shaft 81 coincides with the central axis of the rotating member 39, the length of the transmission shaft 81 is greater than the length of the rotating member 39, a first gear 82 is sleeved on the transmission shaft 81, and a second gear 83 is sleeved on one end of the rotating shaft 6, and the first gear 82 and the second gear 83 are meshingly connected.

[0086] In an optional embodiment, the rotating shaft 6 is rotatably disposed on the second housing 2, for example, the second housing 2 is disposed on the second housing 2 via a bearing. The flexible display screen 5 is meshedly connected with the rotating shaft 6, and the rotating shaft 6 can move along the extension direction of the flexible display screen 5.

[0087] For example, when the rotating shaft 6 rotates clockwise relative to the second shell 2, the rotating shaft 6 can move from one end of the flexible display screen 5 to the other end of the flexible display screen 5 relative to the flexible display screen 5. At this time, the second shell 2 can slide relative to the first shell 1 to move away from the first shell 1, thereby expanding the display part of the flexible display screen 5; when the rotating shaft 6 rotates counterclockwise relative to the second shell 2, the rotating shaft 6 can move from the other end of the flexible display screen 5 to one end of the flexible display screen 5 relative to the flexible display screen 5. At this time, the second shell 2 can slide relative to the first shell 1 to move close to the first shell 1, thereby reducing the display part of the flexible display screen 5.

[0088] In an optional embodiment, if Figure 5 As shown, a first gear tooth 9 is provided on the side of the flexible display screen 5 facing the rotating shaft 6, that is, a first gear tooth 9 is provided on the non-display side of the flexible display screen 5, and a second gear tooth 10 is provided on the peripheral side of the rotating shaft 6, and the rotating shaft 6 and the flexible display screen 5 are meshed and connected via the first gear tooth 9 and the second gear tooth 10.

[0089] For example, the first gear teeth 9 are grooves, and the second gear teeth 10 are protrusions. Alternatively, the side of the flexible display screen 5 facing the rotation axis 6 is provided with an adhesive layer, and the side of the adhesive layer facing away from the flexible display screen 5 is provided with the first gear teeth 9 .

[0090] The length of the rotating shaft 6 is greater than the width of the flexible display screen 5 , and the length direction of the flexible display screen 5 is defined as from one end of the flexible display screen 5 to the other end of the flexible display screen 5 .

[0091] In an optional embodiment, in order to transmit the working medium 33 and facilitate the arrangement of the first cylinder 32 and the second cylinder 34 , the driving assembly 3 further includes a telescopic tube 38 , and the first opening is connected to the second opening through the telescopic tube 38 .

[0092] It should be noted that the telescopic tube 38 has a certain telescopic ability, which can connect the first cylinder 32 and the second cylinder 34 with the shortest length of the telescopic tube 38. For example, the first cylinder 32 is arranged in the first housing 1, and the second cylinder 34 is arranged in the second housing 2. When the second housing 2 slides relative to the first housing 1 to move away from or approach the first housing 1, the telescopic tube 38 has a certain telescopic ability, which can ensure that the hydraulic oil flows between the first cylinder 32 and the second cylinder 34.

[0093] In an optional embodiment, in order to improve the space utilization of the electronic device and make the structure of the electronic device more compact, the first cylinder 32 is disposed in the first shell 1 and the second cylinder 34 is disposed in the second shell 2 .

[0094] The driving assembly 3 also includes a second elastic connector 36 , which can be a spring. One end of the second elastic connector 36 is disposed in one of the first shell 1 and the second shell 2 , and the other end of the second elastic connector 36 is wrapped in a space formed by bending the telescopic tube 38 .

[0095] For example, one end of the second elastic connector 36 is disposed on the first housing 1, and the other end of the second elastic connector 36 is wrapped in a space formed by bending the telescopic tube 38. The telescopic tube 38 is bent along its extension direction to form a plurality of "U"-shaped portions, and the other end of the second elastic connector 36 is wrapped in the "U"-shaped portion. Under the action of the second elastic connector 36, the telescopic tube 38 can always be in a taut state.
