The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

Referring to fig. 1, 4 and 5, in the present embodiment, when the first portion 12 and the second portion 14 move toward each other to the extreme positions (i.e. when the first portion 12 and the second portion 14 approach each other to the point where the first portion 12 and the second portion 14 are engaged, the first portion 12 and the second portion 14 integrally form a substantially rectangular housing 10. Referring to fig. 2, 6 and 7, when the first portion 12 and the second portion 14 are moved apart (i.e., away from each other), the first portion 12 and the second portion 14 are separated.

Referring to fig. 3, 5 and 7, the spool 20 is rotatably disposed in the first portion 12, specifically, the spool 20 is rotatably disposed in the accommodating space 120. That is, the spool 20 is mounted to the first portion 12 and is rotatable relative to the first portion 12. The reel 20 is adapted to be coupled to a drive mechanism 70 such that the reel 20 is capable of rotating relative to the first portion 12 under the drive of the drive mechanism 70 to release or wind up the flexible display 30.

It is understood that the rotational disposition of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12, or may refer to the spool 20 being mounted on the first portion 12 through other media.

Further, with continued reference to fig. 5 and 7, the flexible display screen 30 is fixedly attached at one end to the second portion 14 and is wound up on the spool 20 at the other end. The reel 20 may be used to roll up the flexible display 30 and release the flexible display 30. Wherein upon a separation movement of the first portion 12 and the second portion 14, the spool 20 can be rotated to release the flexible display screen 30, thereby expanding the display portion 301 of the flexible display screen 30. Specifically, one end of the flexible display screen 30 is fixedly connected to the second portion 14, and the other end is connected to the reel 20 disposed in the accommodating space 120 after passing through the first opening 1222 of the first portion 12.

In this manner, upon movement of the first portion 12 and the second portion 14 apart, the spool 20 can be rotated to release the flexible display screen 30, thereby expanding the display portion 301 of the flexible display screen 30. In this way, the size of the screen display area of the mobile terminal 100 can be freely adjusted, the display portion 301 of the flexible display screen 30 can be expanded to improve the user's operation experience when a large screen is required, and at the same time, the display portion 301 can not be expanded when a large screen is not required, so that the whole mobile terminal is small in size and convenient to carry.

It will be appreciated that referring to fig. 5, in one instance, the first portion 12 and the second portion 14 are closely coupled together, in which case the display portion 301 of the flexible display 30 is not expanded, and the mobile terminal 100 is in the narrow screen mode, where a portion of the flexible display 30 is rolled up on the spool 20 and a portion is above the first top plate 122 and exposed from the housing 10 for display. In the present embodiment, the "display portion 301 of the flexible display 30" may be understood as a portion located above the second top plate 142 of the second portion 14, that is, a portion exposed from the housing 10.

Referring to fig. 7, when the display portion 301 of the flexible display screen 30 needs to be expanded, the first portion 12 and the second portion 14 are moved away from each other, so that the second portion 14 drives one end of the flexible display screen 30 to move, and at this time, the reel 20 can release the flexible display screen 30, so that the display portion 301 of the flexible display screen 30 is enlarged, and further, the operation experience and the requirements of the user are improved. In this case, the mobile terminal 100 is in the extended mode.

It will be appreciated that there is a limit to the movement of the second portion 14 and the first portion 12 apart, where the display area of the mobile terminal 100 is greatest, i.e. the area of the flexible display 30 exposed from the housing 10 is greatest, i.e. the area of the display portion 301 of the flexible display 30 is greatest (as shown in fig. 7). When the first portion 12 and the second portion 14 are brought together in close proximity and in a connected fit, the display area of the mobile terminal 100 is smallest, i.e. the display portion 301 of the flexible display 30 is smallest in area (as shown in fig. 5).

One end of the flexible display 30 is fixedly connected to the second portion 14, which may refer to an end of the flexible display assembly 30 being directly fixed to the second portion 14, or may refer to the flexible display assembly 30 being fixed to the second portion 14 through other mediums.

The second transmission structure 74 includes a second transmission gear 742 and a third transmission gear 744, the second transmission gear 742 is fixed on the reel 20 and is disposed concentrically with the reel 20, the third transmission gear 744 is fixedly connected on the motor shaft of the motor, and the third transmission gear 744 is connected to the second transmission gear 742 and the first transmission gear 722, i.e. the third transmission gear 744 is connected to the motor shaft of the motor and is meshed with the second transmission gear 742 and the first transmission gear 722, respectively, and the first transmission gear 722 and the second transmission gear 742 are located on opposite sides of the third transmission gear 744.

In this embodiment, a motor may be used to drive the movement of the second portion 14 relative to the first portion 12 via the first transmission structure 72. At the same time, the motor may also be used to drive the rotation of the spool 20 via the second transmission 74 to release the flexible display 30 while simultaneously driving the second portion 14 in a spaced apart motion relative to the first portion 12.

Specifically, when the display area of the extended mobile terminal 100, that is, the display portion 301 of the extended display layer 32, is required, the third transmission gear 744 may be driven by the motor to rotate, the third transmission gear 744 drives the first transmission gear 722 to rotate, the first transmission gear 722 drives the second portion 14 to perform a separation motion relative to the first portion 12 through the rack portion 724, and at the same time, the second portion 14 drives one end of the flexible display screen 30 to move, and at the same time, the third transmission gear 744 may also drive the second transmission gear 742 to rotate, so as to drive the reel 20 to rotate, so that the reel 20 can synchronously release the flexible display screen 30, and further achieve the purpose of extending the display portion 301 of the flexible display screen 30.

It will be appreciated that when it is desired to reduce the display portion 301 of the flexible display 30, the motor need only be reversed to move the second portion 14 in a direction opposite to the first portion 12, in which case the second portion 14 gradually releases the flexible display 30 and the reel 20 can gradually roll up the flexible display 30.

It will be appreciated that in this embodiment, the movement stroke of the second portion 14 is equal to the length of the flexible display 30 released by rotation of the spool 20 per unit time. That is, the reel 20 is rotated to release a length by a distance by which one end of the flexible display screen 30 is pulled at the second portion 14, so that smooth movement of the flexible display screen 30 without wrinkles can be ensured.

Furthermore, it is also understood that in some embodiments, in order to ensure the smoothness of the winding and releasing of the flexible display 30 by the reel 20, the number of driving mechanisms 70 may be two, the number of the reels 20 may be two, and the two driving mechanisms 70 may be symmetrically disposed in the accommodating space 120 along the longitudinal direction of the mobile terminal 100 and connected to the second portions 14, respectively, and also connected to the two reels 20, respectively. In this way, the synchronous and smooth rotation of the two reels 20 and the smooth movement of the second portion 14 can be achieved by the synchronous driving of the two identical driving mechanisms 70, thereby ensuring the reliability of the movement of the mobile terminal 100 when expanding the display portion 301 of the flexible display screen 30.

Still, in other embodiments, the drive mechanism 70 may also include two synchronous motors disposed on the first portion 12, one motor for driving the second portion 14 relative to the first portion 12, and the other motor for driving the spool 20 in rotation, both driven by separate motors. In this way, the two motors move synchronously, and the stability of the movement of the flexible display screen 30 and the reliability of the movement can be ensured.

In addition, referring to fig. 17, in some embodiments, the driving mechanism 70 may also include a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, where the motor may drive the second portion 14 to move relative to the first portion 12 through the first transmission structure 72, and the second transmission structure 74 may be omitted.

Further, referring to fig. 18-21, in some embodiments, the mobile terminal 100 may further include a restoring mechanism 80, where the restoring mechanism 80 may also be disposed in the accommodating space 120, the restoring mechanism 80 is connected to the scroll 20, and the restoring mechanism 20 is used to apply a restoring force to the flexible display 30 to keep the flexible display 30 in a tendency to be rolled up on the scroll 20.

Specifically, the return mechanism 80 applies a return force to the spool 20, and the spool 20 keeps the flexible display screen 30 in a tendency to roll up on the spool 20 under the return force. That is, when the second portion 14 is not moved relative to the first portion 12 by the external force, the restoring force of the restoring mechanism 80 rotates the reel 20, so that one end of the flexible display 30 is wound up on the reel 20, in which case the first portion 12 and the second portion 14 are completely engaged, and the mobile terminal 100 is in the narrow screen mode.

When the second portion 14 is subjected to an external force and the external force is greater than or equal to the restoring force of the restoring mechanism 80, the second portion 14 moves away from the first portion 12, so as to drive the reel 20 to rotate against the restoring force to release the flexible display screen 30, thereby expanding the display portion 301 of the flexible display screen 30.

It will be appreciated that due to the presence of the return mechanism 80, the return mechanism 80 will always apply tension to the flexible display 30 during expansion of the display portion 301 of the display layer 32, thereby allowing the flexible display to be balanced, i.e., allowing the flexible display 30 to remain flat.

It will also be appreciated that in other embodiments, where the mobile terminal 100 includes the return mechanism 80, the drive mechanism 70 may also include the motor, the first transmission structure 72, and the second transmission structure 74 of the above embodiments, the first transmission structure 72 being coupled to the second portion 12 of the motor, and the second transmission structure 74 being coupled to the first transmission structure 72 and the spool 20. In such an embodiment, when the display area 301 needs to be reduced, the motor may not be operated, but the restoring force of the restoring mechanism 80 is used to reverse the reel 20 to roll up the flexible display 30 and drive the second portion 14 to move towards each other with respect to the first portion 12, i.e. close to the first portion 12.

Further, referring to fig. 19, the restoring mechanism 80 may include an elastic element connected to the spool 20 for applying a restoring force to the spool 20. The elastic element may be a spring, such as a torsion spring as shown in fig. 19, or the like. Of course, the elastic element may be an element having elastic restoring force such as rubber, and is not limited herein.

In further reference to fig. 20, in such an embodiment, the mobile terminal 100 may further include a detent structure 90, the detent structure 90 being provided on the housing 10, the detent structure 90 being configured to limit rotation of the spool 20 when the second portion 14 moves to a predetermined position relative to the first portion 12. That is, the detent structure 90 may prevent the second portion 14 and the flexible display 30 from retracting under the restoring force of the restoring mechanism 80 when the second portion 14 moves to a predetermined position relative to the first portion 12.

Specifically, referring to fig. 20, in the present embodiment, the latch structure 90 may include a latch 92 formed on the first portion 12 and a latch 94 formed on the second portion 14, and when the second portion 14 moves to a predetermined position relative to the first portion 12, the latch 92 is engaged in the latch 94. Thus, even if the external force to the second portion 14 is removed, the second portion 14 and the flexible display 30 will not retract under the restoring force of the restoring mechanism 80 due to the engagement of the latch 92 and the latch groove 94. To ensure that the mobile terminal 100 is in the extended mode.

It should be noted that, the "preset position" may be a relative position between the second portion 14 and the first portion 12 when the second portion moves away from the first portion to the limit position, or may be any position before the limit position.

It will be appreciated that referring to fig. 21, in other embodiments, a clamping groove 94 may be formed in the first portion 12, and a clamping block 92 may be formed in the second portion 14. In addition, in some embodiments, a clamping block may be formed on the first portion 12, a clamping groove is formed on the reel 20, and when the second portion 14 moves to the preset position, the clamping block and the clamping groove are clamped, in this case, the clamping block and the clamping groove can be clamped by a manual pressing manner or an electric driving manner, so that the reel cannot rotate relative to the first portion, and further the second portion 14 and the flexible display screen 30 cannot retract under the action of the restoring mechanism 80. Of course, in other embodiments, the detent structure 90 may also include a catch, and the return mechanism 80 includes a torsion spring, which the catch may catch when the second portion 14 moves to the predetermined position to counteract the return force of the torsion spring. Additionally, it is also understood that in some embodiments, the detent structure 90 may also include a resilient assembly disposed on the first portion 12 and a first catch formed on the second portion 14, the resilient assembly may include a pressing member mounted on the first portion 12, a spring connecting the pressing member and the second catch, and a second catch formed on the second portion 14, the pressing member being operable to move the second catch under the force of an external force through the spring to engage the first catch, thereby defining the relative positions of the first portion 12 and the second portion 14. Thus, when the second portion 14 moves to the preset position, the user can hold the mobile terminal 100 in the extended mode by pressing the pressing member to cause the first and second latching portions to be latched, thereby preventing the second portion 14 from retracting under the restoring force of the restoring mechanism 80. It will be appreciated that upon re-pressing the press, the first and second catch portions disengage, thereby enabling the second portion 14 and the flexible display 30 to retract under the influence of the return mechanism 80 to return the mobile terminal 100 from the extended mode to the narrow screen mode.

Referring again to fig. 17, 18 and 22, in some embodiments, the mobile terminal 100 includes a telescopic support assembly 160, the telescopic support assembly 160 being coupled to the flexible display 30. The telescopic support assembly 160 is capable of being elongated in the extending direction of the flexible display screen 30. The telescopic support assembly 160 includes a plurality of support members 161 and an elastic member 162 connecting the adjacent two support members 161, the plurality of support members 161 being arranged in parallel, and the support members 161 and the elastic member 162 supporting the expansion portion 301 of the flexible display screen 30 in a state in which the telescopic support assembly 160 is fully extended.

In this way, after the flexible display screen 30 is flattened from the reel 20, the telescopic support assembly 160 may be stretched to be in a fully stretched state, at this time, the support member 161 and the elastic member 162 may support the extension portion 301 of the flexible display screen 30, so that the support area of the extension portion of the flexible display screen 30 is larger, the deformation degree of the flexible display screen 30 after being touched after being flattened from the reel 20 is reduced, and the display effect of the flexible display screen 20 is ensured.

It should be noted that the above-mentioned "extension portion" is understood to be a portion of the flexible display screen 30 that protrudes from the first portion 12 and is flattened during the separation movement of the first portion 12 and the second portion 14, i.e. a display portion of the flexible display screen 30 that is enlarged. Hereinafter, the same or similar descriptions are encountered, as well as those understood herein.

It will be appreciated that the telescoping support assembly 160 may also collapse and that the telescoping support assembly 160 may support at least a portion of the display portion 301 of the flexible display screen 30 when the telescoping support assembly 160 is in the collapsed state. Alternatively, in the case where the telescopic support assembly 160 is sufficiently long, the telescopic support assembly 160 may fully support the display portion 301 of the flexible display screen 30. The telescopic support assembly 160 may be extended during the expansion movement of the flexible display screen 30 to support the expanded portion of the flexible display screen 30.

It is understood that when the number of the supporting pieces 161 is greater than or equal to 3, the number of the elastic pieces 162 is greater than or equal to two. The telescopic support assembly 160 is in a fully extended state, which means that the extended length of the telescopic support assembly 160 reaches a maximum value, and at this time, the flexible display screen 30 is also in a fully unfolded state due to the restriction of the telescopic support assembly 160. The extension portion of the flexible display screen 30 is supported on the supporting member 161 and the elastic member 162, so that the supporting area of the extension portion of the flexible display screen 30 can be increased, which is further advantageous in reducing the degree of deformation of the extension portion of the flexible display screen 30.

In the case that the telescopic support assembly 160 is in the unfolded but not fully unfolded state, the area of the extension portion of the flexible display screen 30 is small, and at this time, the extension portion of the flexible display screen 30 is supported on the support member 161, so that the support member 161 can also support the extension portion of the flexible display screen 30, thereby reducing the deformation degree of the extension portion of the flexible display screen 30.

Alternatively, in some embodiments, with the telescoping support assembly 160 in a contracted state, the elastic member 162 is contracted between two adjacent support members 161, the support members 161 supporting at least a portion of the display portion 301 of the flexible display screen 30.

Specifically, the supporting member 161 may have a long strip shape, or may have other specific shapes. In the present embodiment, the support 161 includes a first support part 163 and a connection second support part 164, and the flexible display screen 30 is supported on the first support part 163. The second support 164 may be supported on the first portion 12. The first support portion 163 and the second support portion 164 are connected to form a substantially "T" shape.

The elastic member 162 is, for example, a spring plate, a spring, a colloid, or other elastic element. The elastic member 162 may be elastically deformed such as bending deformation or compression to change its length, thereby changing the overall length of the telescopic support assembly 160.

As in the example of fig. 23, when the elastic member 162 is in the contracted state, the elastic member 162 is bent in a direction away from the flexible display screen 30 to contract between the adjacent two of the supporting members 161. Alternatively, the elastic member 162 is substantially V-shaped, and the telescopic support assembly 160 is in an incompletely unfolded state. When the elastic member 162 is expanded to be substantially "one", the telescopic support assembly 160 is in a fully expanded state, as shown in fig. 24.

In some embodiments, with telescoping support assembly 160 in a fully extended state, a surface 166 of each spring 162 facing flexible display screen 30 is flush with a surface 167 of support 161 facing flexible display screen 30.

In this way, the telescopic support assembly 160 can be extended and contracted under the condition that the plurality of elastic members 162 are rotated, so that the support area of the flexible display screen 30 is larger.

Further, the surface 166 of each elastic member 162 facing the flexible display screen 30 and the surface of the support member 161 facing the flexible display screen 30 are each a flat surface 167.

In some embodiments, the extension 301 of the flexible display screen 30 includes a middle region and an edge region, and the support 161 and the elastic member 162 support the middle region and the edge region in the fully extended state of the telescopic support assembly 160. Alternatively, in the fully extended state of the telescopic support assembly 160, the support member 161 and the elastic member 162 can fully support the extension portion 301 of the flexible display screen 30, so that the extension portion 301 of the flexible display screen 30 is supported and is not easily deformed when touched.

The edge region of the extension portion 301 of the flexible display screen 30 refers to regions on both sides in the longitudinal direction of the extension portion 301 of the flexible display screen 30, and the middle region of the extension portion 301 of the flexible display screen 30 is a region between the two edge regions.

Referring to fig. 23 and 24, in the fully extended state of the telescopic support assembly 160, the distance between two adjacent support members 161 is a first distance L1; in the contracted state of the telescopic support assembly 160, the distance between two adjacent support members 161 is a second distance L2, and the ratio of the first distance L1 to the second distance L2 is greater than 2.

That is, after the telescopic support assembly 160 is extended, the support area of the whole telescopic support assembly 160 is doubled, which is beneficial for the telescopic support assembly 160 to support the display portion of the flexible display screen 30.

In some embodiments, the elastic members 162 are rotatably connected at both ends thereof to the adjacent two supporting members 161, respectively. Alternatively, one end of the elastic member 162 is rotatably connected to one of the adjacent two support members 161, and the other end is rotatably connected to the other of the adjacent two support members 161. In this manner, the connection position of the elastic member 162 and the supporting member 161 can be moved so as to adapt to the external force, so that the elastic member 162 is elastically deformed by the external force. In one example, the elastic member 162 may be rotatably coupled to the support member 161 through a pin.

In some embodiments, the first support 161 is fixedly coupled to the first portion 12 and the second support 161 is fixedly coupled to the second portion 14 in the telescoping direction of the telescoping support assembly 160.

As such, telescoping support assembly 160 may telescope with first portion 12 and second portion 14 in a spaced apart motion to support flexible display screen 30. The support 161 may be fixedly coupled to the first and

second portions

12 and 14 by means of screws or the like.

In some embodiments, a telescoping support assembly 160 is positioned between the first top panel 122 and the flexible display screen 30, and a support 161 is supported on the first top panel 122, the first support 161 being fixedly connected to the first top panel 122.

As such, the first top plate 122 may provide support for the support 161 such that the support 161 may stably support the extended portion of the flexible display screen 30 when the flexible display screen 30 is touched, reducing the amount of deformation of the extended portion of the flexible display screen 30.

Specifically, the first top plate 122 is disposed opposite to the display portion 301 of the flexible display screen 30. As can be appreciated, referring to fig. 17 and 18, when the first portion 12 and the second portion 14 are moved apart, there is a height difference between the upper surface of the first top plate 122 and the upper surface of the second top plate 142, and the flexible display screen 30 is fixedly connected to the upper surface of the second top plate 142.

Therefore, the height of the telescopic support assembly 160 may fill the gap between the first top plate 122 and the flexible display screen 30, so that the extension portion of the flexible display screen 30 may be kept flat when the flexible display screen 30 moves, thereby reducing the pressing deformation, collapse and dislocation phenomenon of the display layer 32 when touched when the mobile terminal 100 is in the extension mode, and improving the user's operation experience.

In some embodiments, the second portion 14 includes a second top plate 142 disposed opposite the first top plate 122, and a portion of the display portion 301 of the flexible display screen 30 is attached to the second top plate 142, with the tail support 161 fixedly attached to the second top plate 142. As such, the telescopic support assembly 160 may be telescopic with the movement of the second top plate 142, thereby supporting the expanded portion of the flexible display screen 30.

It is understood that in the extended state (extended mode) of the flexible display screen 30, the display portion 301 of the flexible display screen 30 includes an extended portion. The second top plate 142 may be omitted if the telescopic support assembly 160 is long enough in the contracted state to support the display portion 301 of the flexible display screen 30. At this time, the telescopic support assembly 160 is in an extended state, and may also support the extended portion of the flexible display screen 30.

Note that in the example of fig. 17 and 18, the mobile terminal 100 omits the limiter 40 and the driving mechanism 70, and at this time, the second portion 14 may be manually pulled to expand the display portion 301 of the flexible display screen 30 and elongate the telescopic support assembly 160.

In the example of fig. 15 and 16, the mobile terminal 100 includes a first transmission gear 722, and at this time, a motor may drive the first transmission gear 722 to rotate to drive the second portion 14 to rotate, so as to expand the display portion 301 of the flexible display 30 and elongate the telescopic support assembly 160. Another motor may drive the rotation of the spool 20 to release the flexible display 30.

In the example of fig. 5 and 7, the mobile terminal 100 may synchronize the movement of the second portion 14 with the reel 20 through the first, second, and third driving gears 722, 724, 744, thereby expanding the display portion 301 of the flexible display 30 and extending the telescopic support assembly 160, and releasing the flexible display 30 from the reel 20.

Referring to fig. 4 to 7, the operation principle of the mobile terminal 100 according to the present embodiment will be described.

As described above, the mobile terminal 100 can switch between the narrow screen mode and the extended mode. In the state shown in fig. 4 and 5, the mobile terminal 100 is in the narrow screen mode, and in the state shown in fig. 6 and 7, the mobile terminal 100 is in the extended mode. When in the narrow screen mode, the first portion 12 and the second portion 14 cooperate to form the housing 10, one end of the flexible display screen 30 is wound on the reel 20, and the other end is connected to the second portion 14, at this time, only a smaller portion of the flexible display screen 30 is exposed from the housing 10, and the display portion 301 is narrower, so that the portable display screen can be carried by a user.

When a user needs a larger display portion 301, the driving mechanism 70 may drive the second portion 14 to perform a separation motion with respect to the first portion 12, at this time, the second portion 14 drives one end of the flexible display screen 30 to move, and at the same time, the driving mechanism 70 also drives the reel 20 to rotate and release the flexible display screen 30, so that a portion of the flexible display screen 30 hidden in the housing 10 is gradually pulled out by the second portion 14 (i.e. moves from the state shown in fig. 4 to the state shown in fig. 6), thereby achieving the purpose of expanding the display portion 301 of the flexible display screen 30, and at this time, the area of the display portion 301 is larger, which may be convenient for the user to operate to improve the operation experience of the user. At the same time, the telescopic support assembly 160 is extended to support the extended portion of the flexible display screen 30.

When the expansion mode is required to be switched to the narrow screen mode, the motor of the driving mechanism 70 is required to be reversed to drive the second part 14 to move relatively to the first part 12, so that the flexible display screen 30 is released, at the moment, the scroll 20 is correspondingly reversed to synchronously roll up the flexible display screen 30, when the flexible display screen moves to the limit position of the opposite movement between the first part 12 and the second part 14, the motor stops running, and the mobile terminal 100 returns to the narrow screen mode.

In summary, the mobile terminal 100 of the present embodiment includes the housing 10, the reel 20, the flexible display 30, and the telescopic support assembly 160. The housing 10 includes a first portion 12 and a second portion 14 that are capable of relative movement. The spool 20 is rotatably disposed on the first portion 12. One end of the flexible display screen 30 is connected to the second portion 14 and the other end is wound up on the spool 20. Upon movement of the first portion 12 and the second portion 14 apart, the spool 20 can be rotated to release the flexible display screen 30, thereby expanding the display portion 301 of the display layer 32. The telescoping support assembly 160 is connected to the flexible display screen 30. The telescopic support assembly 160 is capable of being elongated in the extending direction of the flexible display screen 30. The telescopic support assembly 160 includes a plurality of support members 161 and an elastic member 162 connecting the adjacent two support members 161, the plurality of support members 161 being arranged in parallel, and the support members 161 and the elastic member 162 supporting the expansion portion 301 of the flexible display screen 30 in a state in which the telescopic support assembly 160 is fully extended.

In the mobile terminal 100 of this embodiment, after the flexible display screen 30 is flattened from the reel 20, the telescopic support assembly 160 may be stretched to be in a completely stretched state, at this time, the support member 161 and the elastic member 162 may support the extension portion 301 of the flexible display screen 30, so that the support area of the extension portion of the flexible display screen 30 is larger, the deformation degree of the flexible display screen 30 after being touched after being flattened from the reel 20 is reduced, and the display effect of the flexible display screen 20 is ensured.
