Referring to fig. 1-6, in the present embodiment, the housing assembly 10 includes a first housing 11 and a second housing 12.

The first housing 11 includes a first casing 111 and a first bracket 112, the first casing 111 may be substantially rectangular, and the first bracket 112 is accommodated in the first casing 111 and is fixedly connected to the first casing 111. The first bracket 112 is formed with a first receiving cavity 1121, and the first receiving cavity 1121 can be used for placing components such as the main board 50 and the battery 60. Further, the driving mechanism 31 of the power module 30 is mounted on the first bracket 112, and the driving mechanism 31 is connected to the second housing 12.

The second housing 12 is located at one side of the first housing 11, and the second housing 12 is slidably connected to the first housing 11. Specifically, the second housing 12 includes a second casing 121 and a second bracket 122, and the second casing 121 may also be substantially rectangular, and the second casing 121 and the second casing 111 are slidably connected. The second bracket 122 is accommodated in the second housing 121 and is fixedly connected with the second housing 121, and the second bracket 122 is slidably connected with the first bracket 112.

The second bracket 122 is formed with a second receiving cavity 1221, and the second receiving cavity 1221 can be used for receiving the first bracket 112. Specifically, when the second housing 12 slides relative to the first housing 11, the first housing 111 slides relative to the second housing 121, and the second bracket 122 slides in the second receiving cavity 1221 of the second bracket 122. It is understood that, in the embodiment of the present application, the first bracket 112 may be completely received in the second receiving cavity 1221 or partially received in the second receiving cavity 1221. In addition, the second bracket 122 is connected to the driving mechanism 31 on the first bracket 112, and the driving mechanism 31 can drive the second bracket 122 to slide relative to the first bracket 112 so as to drive the second housing 121 to slide relative to the first housing 111.

In embodiments of the present application, the first housing 111, the second housing 121, the first bracket 112, and the second bracket 122 may be formed of plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The first housing 11 and the second housing 12 may be made of the same or different materials, and are not limited.

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

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, in an example, a plurality of protrusions 1122 are formed on a surface of the first bracket 112, the plurality of protrusions 1122 are arranged at intervals, and the protrusions 1122 may be a plurality of protrusions protruding from the first bracket 112, and the protrusions extend along a sliding direction of the first bracket 112 and the second bracket 122. The second bracket 122 has a plurality of recesses 1222 formed on a surface thereof, the recesses 1222 are spaced apart from each other, the recesses 1222 are a plurality of grooves recessed downward from the surface of the second bracket 122, the grooves are formed along the first direction and the sliding direction of the second bracket 122, in the illustrated embodiment, the recesses 1222 penetrate the top of the second bracket 122 to communicate with the second receiving chamber 1221, and the recesses 1222 correspond to the projections 1122 of the first bracket 112 such that the projections 1122 can be engaged with the recesses 1222.

As the second bracket 122 slides relative to the first bracket 112, the plurality of protrusions 1122 of the first bracket 112 are able to slide within the plurality of recesses 1222 of the second bracket 122, and the surface of the second bracket 122 forming the recesses 1222 is flush with the top surface of the protrusions 1122.

In this way, in the present embodiment, the concave portion 1222 and the convex portion 1122 are engaged, so that the sliding of the second bracket 122 with respect to the first bracket 112 can be more smoothly and reliably performed. Meanwhile, the surface of the second bracket 122 forming the recess 1222 and the top surface of the protrusion 1122 are flush, so that no height difference is formed between the second bracket 122 and the first bracket 112 when the second bracket is slid relative to the first bracket, thereby ensuring the flatness of the electronic device 100. It should be noted that, in this document, "flush" 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.

In the present embodiment, the first bracket 112 has a recess 1222 formed therein, and the second bracket 122 has a projection 1122 formed therein at its insertion portion. It is understood that in other embodiments, the first bracket 112 may be formed with the protrusion 1122 and the second bracket 122 may be formed with the recess 1222. Alternatively, the first bracket 112 may be formed with the projection 1122 and the recess 1222 at the same time, the second bracket 122 may be formed with the recess 1222 and the projection 1122 at the same time, the projection 1122 of the first bracket 112 may be engaged with the recess 1222 of the second bracket 122, and the recess 1222 of the first bracket 112 may be engaged with the projection 1122 of the second bracket 122, and the specific arrangement is not limited herein.

Referring to fig. 5-10, in the present embodiment, the flexible display 20 includes a first portion 21 and a second portion 22 connected to the first portion 21, the first portion 21 is fixedly connected to the first bracket 112 of the first housing 11, the first portion 21 is exposed from the housing assembly 10, and the second portion 22 can be hidden in the housing assembly 10. Specifically, in the illustrated embodiment, the second portion 22 can be concealed within the second housing 12.

The first portion 21 is located above the first bracket 112, and the first portion 21 covers the first bracket 112 and is fixedly connected to the first bracket 112. The first bracket 112 may support the first portion 21. The second portion 22 has one end connected to the first portion 21 and the other end hidden in the second housing 12 after passing around the second bracket 122 and connected to the transmission mechanism 32 of the power assembly 30. While the driving mechanism 31 of the power assembly 30 drives the second housing 12 and the transmission mechanism 32 disposed on the second housing 12 to move relative to the first housing 11, the transmission mechanism 32 of the power assembly 30 can also drive the second portion 22 to move relative to the second housing 12, so that the second portion 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10, fig. 9 is a schematic diagram of the second portion 22 being fully retracted into the housing assembly 10, and fig. 10 is a schematic diagram of the second portion 22 being partially extended out of the housing assembly 10.

In this way, when the area of the display area of the electronic device 100 needs to be enlarged, the power assembly 30 can drive the second portion 22 of the flexible display screen 20 to be exposed from the housing assembly 10, so that the first portion 21 and the exposed second portion 22 jointly form the display area of the electronic device 100, and the display area is enlarged.

It should be noted that in this application, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact with each other through another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the present embodiment, the first portion 21 and the convex portion 1122 on the first bracket 112 may be fixed by a double-sided tape. It is understood that in other embodiments, other fixing methods are also used, for example, magnetic attraction can be used for fixing, specifically, in such embodiments, an element with magnetism can be attached to the back surface of the first portion 21, the convex portion 1122 on the second bracket 122 can be made of magnetic material, and the two are magnetically attracted together, and the specific arrangement is not limited herein.

In addition, in the present embodiment, in a normal state, only the first portion 21 of the flexible display 20 is usually exposed from the housing assembly 10, and at this time, only the first portion 21 is used for displaying, and the display area of the electronic device 100 is small.

When the display area of the electronic device 100 needs to be enlarged, the power assembly 30 can drive the second housing 12 to slide in a direction away from the first housing 11 relative to the first housing 11, and simultaneously drive the second portion 22 to move relative to the second housing 12, so that the second portion 22 is gradually exposed out of the housing assembly 10. At this time, the first portion 21 and the second portion 22 exposed from the inside of the housing assembly 10 together constitute a display area of the electronic device 100, and the display area becomes large.

It can be understood that, in such a case, if the display area of the electronic device 100 needs to be reduced, the second housing 12 and the second portion 22 only need to be driven by the power assembly 30 to move in opposite directions, so that the second portion 22 can be retracted into the housing assembly 10, and thus the display area of the electronic device 100 is reduced, which is convenient for the user to carry. In this way, the second housing 12 and the second portion 22 can be moved by the power assembly 30, so that the electronic device 100 can be switched between a large screen and a small screen in a limited space.

It will be appreciated that when the second portion 22 is exposed from the housing assembly 10, the exposed portion is positioned above the second shelf, and the exposed portion of the second portion 22 substantially conforms to a surface of the second support 122, such that the second support 122 supports the exposed portion of the second portion 22.

It should be noted that, in this document, "fit" may be understood as the contact between the two without affecting the sliding between the two, or may be understood as the gap between the two is within the assembling error range. That is, second portion 22 is movable relative to second bracket 122 by power assembly 30.

In the present embodiment, since the surfaces of the convex portions 1122 and the concave portions 1222 are flush with each other, when the second portion 22 is exposed to the housing assembly 10, there is no difference in height between the portion of the second portion 22 exposed from the housing assembly 10 and the first portion 21, or the difference in height is within an error range without affecting the user experience. Thus, it is ensured that the display area of the electronic device 100 does not have the problem of unevenness.

In addition, it can be understood that, in the present embodiment, the number of the concave portions 1222 and the convex portions 1122 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 21 and the second portion 22 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 concave portions 1222 and the convex portions 1122 can be set according to the actual situation.

In addition, referring to fig. 7-10, in the present embodiment, the second casing 12 further includes a partition plate 123, the partition plate 123 is disposed at the bottom of the second bracket 122 and is fixedly connected to the second bracket 122, and a part of the second portion 22 is located between the partition plate 123 and the second bracket 122.

In this manner, the diaphragm 123 and the second support 122 may limit the second portion 22 from moving only within the channel between the diaphragm 123 and the second support 122 during movement of the second portion 22, thereby guiding movement of the second portion 22 and preventing wrinkling of the second portion 22. Meanwhile, the presence of the second partition 123 may prevent the second part 22 from being damaged due to friction with the second case 121 during the process of being unfolded out of the second case 12 or being retracted into the second case 12.

Referring to fig. 3, in the present embodiment, the number of the power assemblies 30 is two, and the two power assemblies 30 are respectively disposed in the housing assembly 10 and located at two symmetrical sides of the housing assembly 10. In the present embodiment, the specific structures of the two power assemblies 30 are substantially the same, and in order to avoid redundancy, only the specific structure of one of the power assemblies 30 will be described below.

Referring to fig. 5-12, in the present embodiment, the power assembly 30 includes a driving mechanism 31 and a transmission mechanism 32. The driving mechanism 31 is disposed on the first support 112 of the first housing 11, and the driving mechanism 31 is connected to the second support 122 of the second housing 12 and the transmission mechanism 32. The actuator 32 is disposed on the second bracket 122 of the second housing 12 and is coupled to the second portion 22 of the flexible display screen 20. The driving mechanism 31 is used for driving the second housing 12 and the transmission mechanism 32 to slide relative to the first housing 11, and simultaneously driving the second housing 12 and the transmission mechanism 32 to move, the transmission mechanism 32 is driven to synchronously drive the second portion 22 to move relative to the second housing 12, so that the second portion 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10. That is, in the present embodiment, the driving mechanism 31 can drive the second portion 22 to move relative to the second housing 12 through the transmission mechanism 32 at the same time as the driving mechanism 31 drives the second housing 12 to move.

In the present embodiment, the driving mechanism 31 includes a power member 311, a first screw 312, and a first moving member 313.

Referring to fig. 3, in the present embodiment, the power component 311 includes a motor 3111 and a gear module 3112 connected to the motor 3111, the gear module 3112 is connected to the first lead screw 312, and the motor 3111 is configured to drive the first lead screw 312 to rotate through the gear module 3112.

Specifically, referring to fig. 14-15, in the present embodiment, the gear module 3112 includes a driving gear 3113, a transmission gear 3114 and a driven gear 3115, and the driving gear 3113 is connected to a motor shaft of the motor 3111. Driven gear 3115 connects first lead screw 312, and drive gear 3114 meshes in driving gear 3113 and driven gear 3115 respectively, and motor 3111 can drive driving gear 3113 and rotate to drive driven gear 3115 through drive gear 3114 and rotate and then drive first lead screw 312 and rotate. It is understood that in other embodiments, the gear module 3112 may employ more gear sets than the 3 illustrated. Of course, in some embodiments, the power unit 311 may also drive the first lead screw 312 by using other transmission methods, such as worm and gear transmission or transmission, which is not limited herein.

In the present embodiment, the first screw 312 is fixedly connected or detachably connected to the driven gear 31155, or the first screw 312 and the driven gear 3115 are integrally molded and fixed to each other.

The first lead screw 312 extends in the sliding direction of the second housing 12. The first moving member 313 is sleeved on the first lead screw 312 and is in threaded connection with the first lead screw 312. Meanwhile, the first moving member 313 is also fixedly connected with the second support 122 of the second housing 12.

In addition, the first lead screw 312 is also connected to the transmission mechanism 32. The motor 3111 drives the first lead screw 312 to rotate through the gear module 3112 to drive the transmission mechanism 32 to move, and meanwhile, the first lead screw 312 also drives the first moving part 313 to move on the first lead screw 312, so as to drive the second housing 12 to slide relative to the first housing 11.

Referring to fig. 4-7, in some embodiments, the driving mechanism 31 further includes a supporting frame 314 and a supporting member 315, the supporting frame 314 is fixedly mounted on the first bracket 112 of the first housing 11 through a fixing element such as a screw, that is, the supporting frame 314 is fixedly connected to the first housing 11, the supporting member 315 is disposed on the supporting member 315, one end of the first lead screw 312 penetrates through the supporting member 315 and can rotate in the supporting member 315, and the other end is connected to the transmission mechanism 32. In this way, the support 315 can support the first lead screw 312 without interfering with the rotation of the first lead screw 312. Specifically, the support 315 may be a bearing, and the support bracket 314 may be a bearing seat for mounting and supporting the bearing.

In addition, in such an embodiment, the first lead screw 312 is further formed with a threaded structure through one end of the support bracket 314, on which a nut 316 is disposed. As such, the nut 316 may prevent the first lead screw 312 from being separated from the support 315 so that the first lead screw 312 can be stably supported.

Referring to fig. 9-12, in the present embodiment, the transmission mechanism 32 includes a second screw rod 321, a second moving member 322 and a connecting member 323.

The second screw rod 321 is hollow tubular, and the first screw rod 312 is sleeved in the second screw rod 321 and is slidably connected with the second screw rod 321, that is, the second screw rod 321 is sleeved on the first screw rod 312 and is slidably connected with the first screw rod 312.

Specifically, referring to fig. 16-17, a protrusion 3211 is formed on an inner wall of the second screw rod 321, a groove 3121 is formed on the first screw rod 312, the groove 3121 and the protrusion 3211 cooperate to enable the second screw rod 321 to slide relative to the first screw rod 312, and the first screw rod 312 can drive the second screw rod 321 to rotate through the protrusion 3211 and the groove 3121, so that the first screw rod 312 can drive the second screw rod 321 to rotate and can also slide relative to each other. It is understood that the groove 3121 and the projection 3211 are formed to extend in the sliding direction of the second housing 12.

In the illustrated embodiment, the first lead screw 312 has a groove 3121 formed therein, and the second lead screw 321 has a protrusion 3211 formed therein. It is understood that, in other embodiments, the first lead screw 312 may have a protrusion 3211 formed thereon, and the second lead screw 321 may have a groove 3121 formed thereon, which is not limited herein.

Referring to fig. 3 and 9-12, the second moving member 322 is sleeved on the second screw rod 321 and is in threaded connection with the second screw rod 321, and meanwhile, the second moving member 322 is also fixedly connected with the second portion 22 through the connecting member 323.

In addition, referring to fig. 18 to 19, a protrusion 3221 is formed on the second moving part 322, a sliding slot 1223 is formed on the second support 122 of the second housing 12, and the protrusion 3221 and the sliding slot 1223 cooperate to limit the second moving part 322 to rotate along the circumferential direction, and at the same time, the second moving part 322 is slidably connected to the second support 122. Thus, when the second screw rod 321 rotates, due to the matching structure of the protrusion 3221 and the sliding slot 1223, the second screw rod 321 will not rotate at the same time as the second moving part 322, but only drive the second moving part 322 to move on the second screw rod 321 in a threaded manner,

the connecting member 323 is in a long strip shape, the connecting member 323 connects the two second moving members 322 disposed at two sides of the second casing 12, that is, the connecting member 323 extends from one side of the second casing 12 to the opposite side thereof, and the flexible display screen 20 is fixedly connected to the connecting member 323. In this way, the connecting member 323 substantially crosses the second bracket 122 in the longitudinal direction, so that the connecting area of the flexible display 20 and the connecting member 323 is larger to enable the connecting member 323 to better carry the second portion 22 of the flexible display 20. It is understood that two power assemblies 30 may share one connecting member 323, that is, two second moving members 322 disposed at both sides of the second housing 12 may be connected by the same connecting member 323, and the two power assemblies 30 move synchronously, so as to drive the connecting member 323 to move to drive the second portion 22 to move. Of course, in other embodiments, two different connecting members 323 can be provided for two power assemblies 30, and are not limited in particular.

Referring to fig. 7-12, the transmission mechanism 32 further includes a screw rod support 324, one end of the second screw rod 321 is connected to the first screw rod 312, and the other end is disposed in the screw rod support 324 and can rotate relative to the screw rod support 324. It is understood that in some embodiments, the lead screw bracket 324 can be a bearing bracket with a bearing disposed therein, and the second lead screw 321 is connected with an inner ring of the bearing. Of course, the lead screw bracket 324 may also adopt other manners, and only needs to be able to support the second lead screw 321 without affecting the rotation of the second lead screw 321.

As can be seen from the above, in the present embodiment, when the power member 311 drives the first lead screw 312 to rotate, on the one hand, the first lead screw 312 drives the first moving element 313 to move on the first lead screw 312, so as to drive the second housing 12 to slide relative to the first housing 11. On the other hand, the first lead screw 312 drives the second lead screw 321 to rotate through the matching structure of the groove 3121 and the protrusion 3211, so that the second lead screw 321 drives the second moving member 322 to move on the second lead screw 321, and thus the second moving member 322 drives the second portion 22 of the flexible display screen 20 to move through the connecting member 323, so that the second portion 22 gradually expands out of the housing assembly 10 or retracts into the housing assembly 10.

Specifically, when the second casing 12 is relatively far away from the first casing 11, the second moving part 322 synchronously and gradually drives the second portion 22 to be unfolded out of the casing assembly 10 and the moving stroke thereof is the same as the movement of the second casing 12, and the second support 122 of the second casing 12 supports the exposed portion of the second portion 22 and the portion of the casing assembly 10. When the second housing 12 is relatively close to the first housing 11, the second moving part 322 drives the second portion 22 to gradually retract into the housing assembly 10.

In the illustrated embodiment, the number of the power assemblies 30 is two and the two power assemblies are respectively disposed at two symmetrical sides of the housing assembly 10, so that the synchronous driving of the two sides is realized to ensure the stable sliding of the second housing 12 and the stable movement of the second portion 22 of the flexible display screen 20. It is understood that in other embodiments, the number of the power assemblies 30 is also one, and a single power assembly 30 may be disposed at an intermediate position of the housing assembly 10, and is not limited herein, and only needs to be able to stably drive the second housing 12 and the second portion 22 to move.

Specifically, in the illustrated embodiment, two power assemblies 30 are disposed within the housing assembly 10 on either side of the battery 60. This facilitates the arrangement of the components in the inner space of the housing assembly 10, and saves the installation space to make the structure of the electronic device 100 more compact.

Referring to fig. 3-4 and fig. 11-12, in the embodiment, the abutting structure 40 is mounted on the second bracket 122 of the second housing 12 and located in the second housing 121, the abutting structure 40 is wound around a middle portion of the second portion 22, and the abutting structure 40 is used for abutting against a middle portion of the second portion 22 to keep the flexible display screen 20 in a tensioned trend.

In this way, when the power assembly 30 drives the second housing 12 to move and drives the second portion 22 to move relative to the second housing 12, the abutting structure 40 can always abut against the middle portion of the second portion 22, so that the flexible display screen 20 is always in a tensioned state during the movement process without generating a wrinkle phenomenon, and the second portion 22 can be smoothly unfolded outside the housing assembly 10 or retracted into the housing assembly 10.

Referring to fig. 3, in the present embodiment, the supporting structure 40 includes a supporting shaft 41 and an elastic component 42. The number of the elastic assemblies 42 is two, the two elastic assemblies 42 are respectively installed at two sides of the second bracket 122, two ends of the abutting shaft 41 are respectively connected with one elastic assembly 42, and the abutting shaft 41 can rotate relative to the elastic assembly 42. That is, the holding shaft 41 can rotate relative to the elastic member 42. The middle portion of the second portion 22 of the flexible display 20 is wrapped around the axis 41. The elastic component 42 is used to apply a force to the holding shaft 41 to keep the holding shaft 41 in a tendency of holding against the middle portion of the second portion 22, so that the flexible display 20 keeps a tendency of being tensioned.

Referring to fig. 4 and fig. 11-13, in the present embodiment, the elastic element 42 includes a supporting frame 421, a sliding block 422 and an elastic element 423. The holder 421 is mounted on the second bracket 122 by fixing members such as screws. The sliding block 422 is disposed in the supporting frame 421, and the end of the supporting shaft 41 penetrates through the sliding block 422 and the supporting frame 421 and can slide relative to the supporting frame 421. Two ends of the elastic element 423 respectively abut against the second housing 12 and the sliding block 422, and the elastic element 423 is used for applying a force to the sliding block 422 to enable the sliding block 422 to move relative to the abutting frame 421, so as to drive the abutting shaft 41 to move, so that the abutting shaft 41 keeps the tendency of abutting against the middle part of the second portion 22. The elastic member 423 may be an elastic member such as a spring.

It should be noted that, in the present embodiment, no matter what state the electronic device 100 is in, the elastic member 423 is in a compressed state, so that the elastic member 423 can constantly apply a force to the abutting shaft 41, and the abutting shaft 41 tends to abut against the second portion 22.

It can be understood that, when it is required to gradually unfold the second portion 22 out of the housing assembly 10, the power assembly 30 drives the second housing 12 and the holding shaft 41 to move away from the side where the first housing 11 is located, and at this time, the holding shaft 41 applies a force to the second portion 22 of the flexible display 20 along the sliding direction of the second housing 12. In such a case, due to the elastic member 423, when the abutting shaft 41 receives the reaction force of the second portion 22, the abutting shaft 41 compresses the elastic member 423, so that the abutting shaft 41 moves toward the side of the first housing 11 to prevent the flexible line display screen from being damaged due to the movement of the second housing 12 resulting in over-tensioning.

When the second portion 22 assembly needs to be retracted into the housing assembly 10, the second housing 12 drives the holding shaft 41 to move toward the side of the first housing 11, at this time, the holding shaft 41 tends to separate from the middle portion of the second portion 22, in such a case, if the elastic member 423 is not present, it may be possible that, during the movement of the second housing 12 due to the untimely movement of the second moving member 322, the second portion 22 exhibits arching and wrinkling, however, in the present embodiment, regardless of whether the second housing 12 moves, the elastic member 423 exerts a force on the holding shaft 41 so that the holding shaft 41 tends to hold the second portion 22, thereby maintaining the flexible display 20 in tension so that the flexible display 20 does not arch and wrinkle as the second portion 22 is gradually retracted into the housing assembly 10.

Next, the operation principle of the electronic device 100 according to the present embodiment will be described.

As described above, the electronic apparatus 100 can switch between the small screen and the large screen. In the state shown in the figures, figures and figures, the electronic device 100 is in the small screen state. In the states shown in fig. 1, 5, and 9, the electronic apparatus 100 is in the large screen state. When the electronic device is in a small screen state, the first housing 11 and the second housing 12 are embedded to form the housing assembly 10 of the electronic device 100, the first portion 21 of the flexible display screen 20 is exposed from the housing assembly 10, and the second portion 22 is hidden in the housing assembly 10, at this time, the area of the display area of the electronic device 100 is small, so that the electronic device is convenient for a user to carry.

When a user needs a larger display area, the power part 311 drives the first lead screw 312 to rotate so as to drive the first moving part 313 to move on the first lead screw 312, thereby driving the second housing 12 to move to a side away from the first housing 11, and at the same time, the first lead screw 312 drives the second lead screw 321 to rotate, so that the second moving part 322 moves on the second lead screw 321 to drive the second portion 22 of the flexible display 20 to move relative to the second casing 12 through the connecting part 323, so that the second portion 22 gradually expands out of the casing assembly 10, in such a case, the first portion 21 and the second portion 22 exposed from the housing assembly 10 together constitute a display area of the electronic device 100, in this way, the area of the portion of the flexible display screen 20 exposed from the housing assembly 10 is large, and at this time, the area of the display area is large, which can facilitate the operation of the user to improve the operation experience of the user. In such a case, the second housing 12 gradually moves away from the first housing 11, and the second bracket 122 gradually moves away from the first bracket 112, i.e., moves from the state shown in fig. 1 to the state shown in fig. 2. It can be understood that, referring to fig. 2, fig. 6 and fig. 10, the area of the display area of the electronic device 100 is the largest, and at this time, the electronic device 100 is in the large screen state.

When the large screen state needs to be switched to the small screen state, the second housing 12 can be driven to move in the reverse direction only by driving the first lead screw 312 to rotate in the reverse direction through the power component 311, and the second moving part 322 drives the second portion 22 to move in the reverse direction, so that the second portion 22 is gradually retracted into the housing assembly 10. When the first housing 11 and the second housing 12 are fitted together, the power unit 311 stops operating, and the electronic apparatus 100 returns to the small screen state (i.e., moves from the state shown in fig. 2 to the state shown in fig. 1).

In summary, the electronic device 100 according to the embodiment of the present disclosure includes the housing assembly 10, the flexible display 20, and the power assembly 30. The housing assembly 10 includes a first housing 11 and a second housing 12 that are slidable relative to each other. The flexible display 20 includes a first portion 21 exposed from the housing assembly 10 and a second portion 22 connected to the first portion 21 and capable of being hidden in the housing assembly 10, wherein the first portion 21 is connected to the first housing 11. The power assembly 30 comprises a driving mechanism 31 disposed on the first housing 11 and a transmission mechanism 32 disposed on the second housing 12, the driving mechanism 31 is connected with the second housing 12 and the transmission mechanism 32, and the transmission mechanism 32 is connected with the second portion 22.

The driving mechanism 31 is configured to drive the second housing 12 and the transmission mechanism 32 to slide relative to the first housing 11, and drive the second housing 12 and the transmission mechanism 32 to move, and simultaneously drive the transmission mechanism 32 to synchronously drive the second portion 22 to move relative to the second housing 12, so that the second portion 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10.

It should be noted that, as mentioned above, the phrase "synchronously moving the second portion 22 relative to the second housing 12" can be understood to mean that the transmission assembly 32 synchronously moves the second portion 22 while the driving mechanism 31 moves the second housing 12, the moving stroke of the second portion 22 is equal to the moving stroke of the second housing 12, and the moving stroke of the second portion 22 relative to the first housing 11 is equal to twice the moving stroke of the second housing 12.

In summary, in the electronic device 100 according to the embodiment of the present application, the driving mechanism 31 of the power assembly 30 can drive the second housing 12 and the transmission mechanism 32 to move, and the transmission mechanism 32 can synchronously drive the second portion 22 to move, so that the second portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10, and the size of the display area of the electronic device 100 can be changed. In this way, the moving state of the second housing 12 and the second portion 22 can be changed by the power assembly 30 to change the area of the portion of the flexible display 20 outside the housing assembly 10, so that the electronic device 100 can switch between a large screen and a small screen of the electronic device 100 in a limited space.
