Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1 to 2, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure, and fig. 2 is a second structural schematic diagram of the electronic device according to the embodiment of the present disclosure. An electronic device such as electronic device 20 of fig. 1 may be a computing device such as a laptop computer, a computer monitor containing an embedded computer, a tablet, a cellular telephone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a hanging device, an earphone or headphone device, a device embedded in eyeglasses, or other device worn on the head of a user, or other wearable or miniature device), a television, a computer display not containing an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or automobile), a device that implements the functionality of two or more of these devices, or other electronic devices. In the exemplary configuration of fig. 1, the electronic device 20 is a portable device, such as a cellular telephone, media player, tablet computer, or other portable computing device. Other configurations may be used for the electronic device 20, if desired. The example of fig. 1 is merely exemplary.

Referring to fig. 3, fig. 3 is an exploded view of the electronic device shown in fig. 1. The electronic device 20 may include a first carrier 100, a second carrier 200, and a flexible screen assembly 300. The first and

second carriers

100 and 200 are slidably coupled such that the first and

second carriers

100 and 200 are relatively moved in a direction approaching or departing from each other, so that switching between the unfolded state and the folded state can be achieved. In this case, a furled state may be referred to as fig. 1, i.e., a state in which the first carrier 100 and the second carrier 200 are relatively moved in a direction to approach each other to be finally formed. In this case, the unfolded state may refer to fig. 2, i.e., a state in which the first and

second carriers

100 and 200 are relatively moved in a direction away from each other.

It is understood that the first carrier 100 and the second carrier 200 may undergo relative movement to achieve longitudinal stretching of the electronic device 20. Here, the longitudinal drawing refers to a manner of drawing in a direction perpendicular to the display direction of the flexible screen assembly 300. Therefore, the size of the screen display area of the electronic device 20 can be freely adjusted, the display part of the electronic device 20 can be expanded and the operation experience of a user can be improved when a large screen is needed, and meanwhile, the display part can not be expanded when the large screen is not needed, so that the whole device is small in size and convenient to carry.

It should be noted that the spread states of the first carrier 100 and the second carrier 200 may be various, such as the maximum moving distance of the first carrier 100 and the second carrier 200 in the direction away from each other is H, and the first carrier 100 and the second carrier 200 may move away from each other in the folded state to reach the spread states with different distances formed by the equal distance of one quarter H, one half H, and three quarters H. The state of the distance gradually becoming farther may be defined as a first developed state, a second developed state, a third developed state, and the like in this order.

It should be noted that when the first carrier 100 and the second carrier 200 are in the first unfolded state, such as the distance of the relative moving away of the first carrier 100 and the second carrier 200 in the first unfolded state is a quarter H, the first carrier 100 and the second carrier 200 can still perform the relative moving away to reach the second unfolded state, such as the distance of the relative moving away of the first carrier 100 and the second carrier 200 in the second unfolded state is a half H.

It is to be understood that the one or more spread states of the first and

second carriers

100 and 200 of the embodiment of the present application are only illustrative and do not limit the spread states of the first and

second carriers

100 and 200 of the embodiment of the present application.

One end of the flexible screen assembly 300 is fixedly connected to the first carrier 100, and the other end of the flexible screen assembly 300 is fixedly connected to the second carrier 200. The first and

second carriers

100 and 200 may support the flexible screen assembly 300. The first carrier 100 and the second carrier 200 may drive the flexible screen assembly 300 to move together or drive the flexible screen assembly 300 to move during the mutual movement, so that the length of the flexible screen assembly 300 may be adjusted, and the size of the display area of the electronic device may be changed.

When the first and

second carriers

100 and 200 are relatively moved in a direction to approach each other, the first and

second carriers

100 and 200 may drive a portion of the flexible screen assembly 300 to be received inside the electronic device 20, such as inside the first housing 800 of the electronic device 20. The first and

second carriers

100 and 200 may drive a portion of the flexible screen assembly 300 to protrude from the interior of the electronic device 20 when the first and

second carriers

100 and 200 are relatively moved in a direction away from each other.

Wherein, the first casing 800 may be disposed on the periphery of the first carrier 100, and the second casing 900 may be disposed on the periphery of the second carrier 200.

It should be noted that, during the movement of the flexible screen assembly 300, especially when the first carrier 100 and the second carrier 200 move relatively in the direction of approaching each other, the flexible screen assembly 300 may be folded, curled, and deformed by an external force to abut against the first housing 800 of the electronic device 20, so as to generate a friction force, which affects the smoothness of the flexible screen assembly 300 during the movement. It should also be noted that the flexible screen assembly 300 may also be susceptible to damage to the flexible screen assembly 300 and reduce the lifetime of the flexible screen assembly 300 due to long term friction with the first housing 800 of the electronic device 20.

Based on this, in the moving process of the first carrier 100 and the second carrier 200 in the embodiment of the present application, real-time transmission to the flexible screen assembly 300 may be realized through a plurality of transmission structures, so as to prevent the flexible screen assembly 300 from being folded, curled, and the like due to an external force in the moving process to abut against the first housing 800 of the electronic device 20, prevent the flexible screen assembly 300 from forming a friction force with the first housing 800 in the moving process, improve the smoothness of the flexible screen assembly 300 in the moving process, and increase the service life of the flexible screen assembly 300. Such as when a portion of the flexible screen assembly 300 is retracted into the first and

second carriers

100, 200, a traction may be applied to an end of the flexible screen assembly 300 to keep the flexible screen assembly 300 under traction by the applied force during the retraction process without being easily deformed such as loose or wrinkled.

Referring to fig. 4 and fig. 5, fig. 4 is a schematic structural diagram of a portion of the electronic device shown in fig. 1, and fig. 5 is a schematic structural diagram of a portion of the electronic device shown in fig. 2. The first carrier 100 is provided with two sliding slots 120, wherein one sliding slot 120 is located at one side of the first carrier 100, and the other sliding slot 120 is located at the other side of the first carrier 100. It is understood that one side of the first carrier 100 is positioned opposite to the other side of the first carrier 100. The number of the chutes 120 formed in the first carrier 100 is not limited to two. It is also possible that the first carrier 100 is provided with a slide 120 on only one side thereof. The first carrier 100 is provided with two slide grooves 120 for example.

The first and

second carriers

100 and 200 may be moved relative to each other by a driving structure to maintain tension on the flexible screen assembly 300. The driving structure in which the first and

second carriers

100 and 200 move with each other may include two moving members and two driving belts. For example, the driving structure may include a first moving member 140, a second moving member 160, a first driving belt 420, and a second driving belt 440. The first moving member 140 is disposed in one slide groove 120, the second moving member 160 is disposed in the other slide groove 120, the first moving member 140 is movable in one slide groove 120, and the second moving member 160 is movable in the other slide groove 120 to drive the first carrier 100 and the second carrier 200 to move relatively. One end of the first driving belt 420 is connected to the first carrier 100, the other end of the first driving belt 420 is fixedly connected to the other end of the flexible screen assembly 300, and the first driving belt 420 is wound around the first moving member 140 in a bending manner (for example, in a bending manner of 180 degrees); one end of the second belt 440 is fixedly connected to the first carrier 100, the other end of the second belt 440 is connected to the other end of the flexible screen assembly 300, and the second belt 440 is bent (for example, bent 180 degrees) around the second moving member 160, so that when the first moving member 140 and the second moving member 160 move to drive the first carrier 100 and the second carrier 200 to move in a direction approaching each other, the first belt 420 moves around the first moving member 140 and the second belt 440 moves around the second moving member 160 to draw the flexible screen assembly 300 to move together.

As shown in connection with fig. 3, flexible screen assembly 300 may include a flexible screen 320 and a support sheet 340. The flexible screen 320 may be understood as a flexible display screen. The supporting sheet 340 may be made of metal, such as a steel sheet, and the supporting sheet 340 is disposed on the non-display surface of the flexible screen 320 to support the flexible screen 320. The other end of the first belt 420 and the other end of the second belt 440 are connected to the supporting plate 340, for example, by welding.

The first and

second belts

420 and 440 may be wire ropes, one end of which is welded to the first carrier 100 and the other end of which is welded to the support sheet 340 of the flexible screen assembly 300). The steel wire rope may have a cylindrical structure, and the steel wire rope having the cylindrical structure may reduce a contact area between the steel wire rope and the first and second moving

members

140 and 160, and further reduce friction force during relative movement of the steel wire rope and the first and second moving

members

140 and 160, and may extend the service lives of the first and

second transmission belts

420 and 440.

It is understood that when the first carrier 100 and the second carrier 200 move in the approaching direction, the first driving belt 420 and the second driving belt 440 pull the flexible screen assembly 300 together and also move in the approaching direction of the first carrier 100 and the second carrier 200, so that a portion of the flexible screen assembly 300 can be recycled to the inside of the electronic device 20, thereby reducing the overall size of the electronic device 20. And the first transmission belt 420 and the second transmission belt 440 jointly drag the other end of the flexible screen assembly 300, so that the flexible screen assembly 300 is prevented from being easily damaged due to friction with the first shell 800 of the electronic device 20 during movement. In addition, the embodiment of the present application connects the first driving belt 420 to the first moving member 140 disposed at one side of the first carrier 100, and connects the second driving belt 440 to the second moving member 160 disposed at the other side of the first carrier 100, so that a receiving space for receiving other components of the electronic device 20, such as a battery or a circuit board, may be defined between the first driving belt 420 and the first driving belt 420. The device layout design of the embodiment of the present application may make the devices inside the electronic device 20 more compact, compared to directly disposing the transmission structure and/or the driving structure at the middle position of the electronic device 20.

Referring to fig. 5 to 8, fig. 6 is an enlarged schematic structural diagram of a region a in the electronic device shown in fig. 5, fig. 7 is a schematic structural diagram of a first moving element, a first driving belt and a first driving mechanism in the electronic device shown in fig. 5, and fig. 8 is a schematic structural diagram of an explosion of the first moving element, the first driving belt and the first driving mechanism shown in fig. 7.

The surface of the first moving member 140 is provided with a limiting portion 142 in a protruding manner, and the first transmission belt 420 is wound around the limiting portion 142 of the first moving member 140. The surface of the second moving member 160 is also provided with a protruding limiting portion 142, and the second belt 440 is wound around the limiting portion 142 of the second moving member 160. When the first moving member 140 and the second moving member 160 move in the sliding slot 120 in a direction in which the first carrier 100 and the second carrier 200 move away from each other, respectively, the flexible screen assembly 300 is pushed away by the second carrier 200, and at this time, the flexible screen assembly 300 pulls the first driving belt 420 and the second driving belt 440 together to move in a direction in which the first carrier 100 and the second carrier 200 move away from each other, the first driving belt 420 moves around the position-limiting portion 142 on the first moving member 140 while moving, the second driving belt 440 moves around the position-limiting portion 142 on the second moving member 160 while moving, and the flexible screen assembly 300 extends a part of the flexible screen assembly 300 from the inside of the electronic device 20 to the outside of the electronic device 20 under the common effect of the second carrier 200, the first driving belt 420 and the first driving belt 420. It will be appreciated that when the flexible screen assembly 300 receives a pushing force applied thereto by the second carrier 200, the first and second driving

belts

420 and 440 gradually reduce the pulling force on the flexible screen assembly 300, such that a portion of the flexible screen assembly 300 is deployed outside of the electronic device 20.

When the first moving member 140 and the second moving member 160 move in the sliding slot 120 toward the direction in which the first carrier 100 and the second carrier 200 approach each other, the limiting portion 142 on the first moving member 140 drives the first transmission belt 420 to move around the limiting portion 142 on the first moving member 140 while moving, the limiting portion 142 on the second moving member 160 drives the second transmission belt 440 to move around the limiting portion 142 on the second moving member 160 while moving, and the first transmission belt 420 and the second transmission belt 440 jointly pull the flexible screen assembly 300 to move while moving, so that a portion of the flexible screen assembly 300 is recovered from the outside of the electronic device 20 to the inside of the electronic device 20. It will be appreciated that without traction by first and

second belts

420, 440, flexible screen assembly 300 may deform into abutment with first housing 800, thereby causing friction between flexible screen assembly 300 and the inner wall of first housing 800 and damaging flexible screen assembly 300.

In some embodiments, one of the limiting portions 142 may be provided with a limiting groove, the first transmission belt 420 may move in one of the limiting grooves, the second transmission belt 440 may move in the other limiting groove, and the limiting groove may limit the first transmission belt 420 and the second transmission belt 440, so that the first transmission belt 420 and the second transmission belt 440 may not be separated from the limiting portion 142 during the movement.

As shown in fig. 6 to 8, a roller 180 may be sleeved on an outer surface of one of the limiting portions 142, and the roller 180 may rotate relative to the limiting portion 142. The first belt 420 may be wound around one of the rollers 180, and the second belt 440 may be wound around the other roller 180. The first driving belt 420 can drive the roller 180 to rotate around the limiting portion 142 in the process of moving around the roller 180, and for the direct rotation around the limiting portion 142, the roller 180 additionally arranged on the limiting portion 142 can reduce friction on the first driving belt 420, so that the first driving belt 420 can move more smoothly, and abrasion of the first driving belt 420 can also be reduced. Similarly, the second belt 440 can drive the other roller 180 to rotate around the other limiting portion 142 in the process of moving around the other roller 180, and compared with the second belt directly rotating around the other limiting portion 142, the additional arrangement of the roller 180 on the other limiting portion 142 can reduce friction on the second belt 440, so that the second belt 440 moves more smoothly, and wear of the second belt 440 can also be reduced.

In order to increase the stability of the first transmission belt 420 and the second transmission belt 440 during the movement, a limiting groove 182 may be further disposed on the roller 180, the first transmission belt 420 may move in one of the limiting grooves 182, the second transmission belt 440 may move in the other limiting groove 182, and the limiting groove 182 may limit the first transmission belt 420 and the second transmission belt 440, so that the first transmission belt 420 and the second transmission belt 440 may not be separated out of the limiting portion 142 during the movement.

It should be noted that, in the whole movement process of driving the flexible screen assembly 300, the interaction among the first moving member 140, the second transmission member 240, the first transmission belt 420 and the second transmission belt 440 is adopted, so that the flexible screen assembly 300 is always in a limited state, or the flexible screen assembly 300 always has the tension of the interaction among the first moving member 140, the second transmission member 240, the first transmission belt 420 and the second transmission belt 440, and it can also be understood that the interaction among the first moving member 140, the second transmission member 240, the first transmission belt 420 and the second transmission belt 440 always has a traction acting force on one end of the flexible screen assembly 300, so as to pull the flexible screen assembly 300 to move. So that the flexible screen assembly 300 is not easily deformed by external force, such as being formed or curled. Thereby preventing the flexible screen assembly 300 from abutting against housing structures of the electronic device 20, such as the first housing 800, and improving the smoothness of movement of the flexible screen assembly 300. Furthermore, the present embodiment keeps the flexible screen assembly 300 from contacting the housing structure of the electronic device 20, such as the first housing 800, by the traction force during the operation process of the first carrier 100 and the second carrier 200, and also protects the flexible screen assembly 300, thereby prolonging the service life of the flexible screen assembly 300.

The first and second moving

members

140 and 160 may be manually driven to move in the slide groove 120, respectively. Such as applying opposing forces on the first and

second carriers

100 and 200, a force may be applied to the first and second moving

members

140 and 160 to drive the first and second moving

members

140 and 160 to move within the slide slot 120, such that the first and

second carriers

100 and 200 move in a direction away from each other and the flexible screen assembly 300 moves to increase the display area. For example, the first moving member 140 and the second moving member 160 may apply opposite forces to the first moving member 140 and the second moving member 160, and the first moving member 140 and the second moving member 160 may transmit forces to the first driving belt 420 and the second driving belt 440 to drive the first driving belt 420 and the second driving belt 440 to move around the position-limiting portion 142, respectively, so that the first carrier 100 and the second carrier 200 move in a direction to approach each other, and the flexible screen assembly 300 moves to reduce a display area of the flexible screen assembly 300.

The first moving member 140 and the second moving member 160 may be electrically driven to move in the sliding groove 120. If the first moving member 140 and the second moving member 160 are electrically driven to move in the sliding slot 120, the electronic device may further include a driving mechanism, such as a motor, a gear set, and the like.

For example, referring to fig. 5 to 8, the electronic device 20 may further include a first driving mechanism 520 and a second driving mechanism 540, the first driving mechanism 520 is connected to the first moving element 140, the second driving mechanism 540 is connected to the second moving element 160, such as the first driving mechanism 520 may be connected to the fixing portion 144 of the first moving element 140, and the second driving mechanism 540 may be connected to the fixing portion 144 of the second moving element 160. The first driving mechanism 520 may drive the first mover 140 to move, and the second driving mechanism 540 may drive the second mover 160 to move.

The first driving mechanism 520 may include a driving component 522 and a transmission component 524, which are connected to each other, the transmission component 524 is connected to the first moving member 140, the driving component 522 may drive the transmission component 524 to move, and the transmission component 524 drives the first moving member 140 to move together during the movement. The driving assembly 442 may be one or a combination of a screw driving assembly, a gear set, or a telescopic assembly. For example, the transmission assembly 524 includes a base 5242, a transmission screw 5244 and a connector 5246, the base 5242 is disposed on the first carrier 100, the transmission screw 5244 is rotatably coupled to the base 5242, e.g., the transmission screw 5244 can be coupled to a bearing embedded in the base 5242, such that the transmission screw 5244 can rotate relative to the base 5242. The drive screw 5244 is also coupled to the drive assembly 522, which drives the drive screw 5244 to rotate relative to the base 5242. The connecting member 5246 is sleeved on the transmission screw rod 5244, the connecting member 5246 is in transmission connection with the transmission screw rod 5244, the connecting member 5246 is further connected with the first moving member 140, the connecting member 5246 is driven by the transmission screw rod 5244 to reciprocate, so as to drive the first moving member 140 to reciprocate, and when the first moving member 140 reciprocates, the second carrier 200 reciprocates along with the first moving member 140.

The base 5242 is further provided with a groove 5242a, and the connecting member 5246 is arranged on the transmission screw 5244 and positioned in the groove 5242a, and the groove 5242a can play a role in guiding and positioning the movement of the connecting member 5246.

It can be understood that, in the embodiment of the present application, the driving assembly 522 provides an active driving effect, the first moving member 140 and the first driving belt 420 are a combined driven mechanism, and perform linkage motion under the active driving of the driving assembly 522, so that the moving distance of the first moving member 140, the moving distance of the first driving belt 420, and the unfolding length or the recycling length of the flexible screen assembly 300 are equal, and further it is ensured that the flexible screen assembly 300 is in a constantly tightened state (it is ensured that the tension of the flexible screen assembly 300 is within a certain range) in the unfolding process and the recycling process, and abnormal situations such as an excessively large tension of the flexible screen assembly 300 being damaged or an excessively small tension of the flexible screen assembly 300 being wrinkled due to asynchronous unfolding can be avoided.

Referring to fig. 9, fig. 9 is a schematic structural view of the first moving element, the first driving belt, and the connecting member of the first driving mechanism shown in fig. 8. The connecting member 5246 is provided with a through hole 5246a, and the wall of the through hole 5246a is provided with a transmission screw thread which is engaged with the screw teeth of the transmission screw 5244, so that the transmission screw 5244 rotates to drive the connecting member 5246 to linearly move along a direction parallel to the first carrier 100 through the transmission screw thread of the through hole 5246 a. It will be appreciated that rotation of the drive screw 5244 can be translated into linear movement of the connector 5246. The connecting member 5246 is further provided with a locking groove 5246b, and the locking groove 5246b is locked with the fixing portion 144 so as to connect the connecting member 5246 with the first moving member 140. Of course, the connection between the connection member 5246 and the first motion member 140 can be achieved by other means (e.g., welding, bonding, etc.).

Referring to fig. 7 and 8, the driving assembly 522 may include a first driving module 5222 and a first deceleration module 5224, the first driving module 5222 is connected to the first deceleration module 5224, and the first deceleration module 5224 is in transmission connection with the transmission screw 5244. For example, the first deceleration module 5224 can be a reduction gearbox that is coaxially connected to the first drive module, and the reduction gearbox can decelerate the first drive module 5222 to increase torque. The first reduction module 5224 can be connected to the drive screw 5244 through a gear set, for example, the output shaft of the first reduction module 5224 is connected to the first gear 562, the drive screw 5244 is connected to the second gear 564, and the second gear 564 and the first gear 562 are meshed with the third gear 566 to realize the drive connection between the first reduction module 5224 and the drive screw 5244.

Fig. 10 is a schematic view showing a second structure of the first moving member, the first belt, and the first driving mechanism of fig. 8, as shown in fig. 10. In order to further increase the output power of the driving assembly 522 to increase the output thrust of the transmission screw 5244 and the connecting member 5246, the driving assembly 522 of the embodiment of the present application may further include a second driving module 5226 and a second speed reducing module 5228, which are connected to each other, and the second speed reducing module 5228 is in transmission connection with the first speed reducing module 5224. For example, the second speed reducing module 5228 is provided with a fourth gear 568, and the first gear 562 and the fourth gear 568 of the second speed reducing module 5228 are meshed with the fifth gear 569 so as to realize the transmission connection between the second speed reducing module 5228 and the first speed reducing module 5224. The fourth gear 568 on the second reduction module 5228 transfers torque through the fifth gear 569 to the first gear 562 of the first reduction module 5224, and the output torques of the two reduction modules are superimposed. The superimposed torque is transmitted to the drive screw 5244 through the second gear 564, thereby driving the drive screw 5244 to rotate. Compared with the case that only one driving module and one speed reducing module are provided, the thrust generated by the transmission screw rod 5244 and the connecting piece 5246 can be increased by about 80% by the two driving modules and the two speed reducing modules adopted in the embodiment of the application.

It should be noted that the 4 gear pairs consisting of the first gear 562, the third gear 566, the fourth gear 568 and the fifth gear 569 are all semi-rigidly connected. It will be appreciated that at least one of the gears in each gear pair is made of a material having a relatively low modulus of elasticity (e.g., plastic) to avoid the impact problem caused by microscopic asynchrony.

Referring to fig. 11, fig. 11 is a third structural diagram of the first moving element, the first transmission belt and the first driving mechanism of the first driving mechanism shown in fig. 8. The driving assembly 522 may also include two driving modules and one deceleration module, for example, the driving assembly 522 may include a first driving module 5222, a first deceleration module 5224 and a second driving module 5226, the first driving module 5222 is connected in series with the second driving module 5226, and the first deceleration module 5224 may be coaxially connected with the first driving module 5222 or the second driving module 5226. For example, a drive shaft of the first drive module 5222 and a drive shaft of the second drive module 5226 are connected by a coupling 5229 such that the first drive module 5222 and the second drive module 5226 are connected in series. After the two driving modules are connected in series, the speed is reduced through the first speed reducing module 5224, the torque is increased, and the first speed reducing module 5224 synchronously drives the transmission screw 5244 to rotate through the first gear 562 and the second gear 564. The coupler 5229 is made of a material (e.g., plastic) with a small elastic modulus, so that the acting force generated by the small asynchronism when the two driving modules are started can be absorbed by the elastic coupler 5229. At this time, the output terminal of the first driving module 5222 is connected to the input terminal of the second driving module 5226.

Referring to fig. 12 and 13, fig. 12 is a schematic diagram of a partially exploded structure of the first driving mechanism shown in fig. 11, and fig. 13 is a schematic diagram of a coupling in the first driving mechanism shown in fig. 11. The drive shaft of the first drive module 5222 and the drive shaft of the second drive module 5226 are each configured as a semi-cylindrical structure, and have a substantially D-shaped cross section. The coupler 5229 is provided with a connecting hole 5229a, the shape of the connecting hole 5229a is matched with the structure of the drive shaft of the first drive module 5222 and the drive shaft of the second drive module 5226, and the size of the connecting hole 5229a is slightly larger than the size of the drive shaft of the first drive module 5222 and the size of the drive shaft of the second drive module 5226, so that the drive shaft of the first drive module 5222 and the drive shaft of the second drive module 5226 are inserted into the connecting hole 5229a, and a gap exists between the coupler 5229 and the drive shaft of the first drive module 5222 and the drive shaft of the second drive module 5226, and the gap can absorb the acting force generated by slight asynchronization when the two drive modules are started.

In some embodiments, the first drive module 5222 and the second drive module 5226 can also be connected in series and then engaged with a reduction gear via gears to interconnect the two drive modules and one reduction module. At this time, the input terminal of the first driving module 5222 is connected to the input terminal of the second driving module 5226, i.e., the first driving module 5222 and the second driving module 5226 are connected in series.

The structure of the second driving mechanism 540 may be the same as that of the first driving mechanism 520, for example, the second driving mechanism 540 may also include a driving component 542 and a transmission component 544, which are connected to each other, the transmission component 544 is connected to the second moving member 160, the driving component 542 may drive the transmission component 544 to move, and the transmission component 544 drives the second moving member 160 to move together during the movement. The driving assembly 542 and the transmission assembly 544 in the second driving mechanism 540 may be any one of the driving assemblies and the transmission assemblies described above, and details thereof are not repeated herein. For example, drive assembly 542 can include a first drive module 5422 and a first deceleration module 5424 coupled to one another. The first drive module 5422 and the first drive module 5222 of the first drive mechanism 520 have the same structure, and the first deceleration module 5424 and the first deceleration module 5224 of the first drive mechanism 520 have the same structure. Of course, the structure of the second driving mechanism 540 may also be different from that of the first driving mechanism 520, for example, the second driving mechanism 540 may be a gear set transmission or other transmission, and is not limited to the screw transmission described above.

Referring to fig. 5 and 7, the first carrier 100 is provided with a plurality of first plugging portions 110, a first slot 130 is disposed between two adjacent first plugging portions 110, the second carrier 200 is provided with a plurality of second plugging portions 210, a second slot 230 is disposed between two adjacent second plugging portions 210, when the first carrier 100 and the second carrier 200 are connected, the first plugging portion 110 is accommodated in the second slot 230 and the first plugging portion 110 can move in the second slot 230, and the second plugging portion 210 is accommodated in the first slot 130 and the second plugging portion 210 can move in the first slot 130.

Referring to fig. 5, the second carrier 200 further includes a limiting member 220, and the flexible screen assembly 300 is bent (e.g., bent by 180 degrees) around the limiting member 220. When the first moving member 140 and the second moving member 160 move to drive the first carrier 100 and the second carrier 200 to move in the direction away from each other, the limiting member 220 follows the second carrier 200 to move in the direction away from each other, and the limiting member 220 moves while pushing the flexible screen assembly 300 to move toward the outside of the electronic device 20, so as to implement the unfolding function of the flexible screen assembly 300. The limiting element 220 may be in a regular shape, such as a cylinder structure or a semi-cylinder structure, and the limiting element 220 may also be in an irregular shape, for example, one surface of the limiting element 220 may be an arc surface, and the rest surfaces may be surfaces of a straight structure or a wave structure. The limiting member 220 may be an additional component independent from the second carrier 200, and the limiting member 220 may also be a part of the second carrier 200.

As shown in fig. 14, fig. 14 is a schematic structural diagram of a limiting element in the electronic device shown in fig. 3. The limiting member 220 may include a rotating shaft 222 and a roller 224, wherein the roller 224 is disposed on an outer surface of the rotating shaft 222 and is rotatably connected to the rotating shaft 222 (e.g., via a ball joint), such that the roller 224 can rotate around the rotating shaft 222. The flexible screen assembly 300 is wound on the roller 224, and the flexible screen assembly 300 can drive the roller 224 to rotate around the rotating shaft 222 while moving, so that the friction force between the flexible screen assembly 300 and the limiting part 220 can be reduced, the service life of the flexible screen assembly 300 can be prolonged, and the flexible screen assembly 300 can move more smoothly.

The following illustrates, for example, the electronic device 20 in which the first carrier 100 and the second carrier 200 move relative to each other to move the flexible screen assembly 300 and thus change the display area of the flexible screen assembly 300. Referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 6, and fig. 7, fig. 1, fig. 3, and fig. 6 illustrate the first carrier 100 and the second carrier 200 of the electronic device 20 in a folded state. The first carrier 100 and the second carrier 200 may be driven to move away from each other in an electric driving manner to switch to the unfolded state, and fig. 2, 4 and 7 illustrate the first carrier 100 and the second carrier 200 of the electronic device 20 in the unfolded state.

The first driving module 5222 is decelerated by the first deceleration module 5224 to increase torque, the transmission screw 5244 is driven to rotate by the first gear 562 and the second gear 564, the connecting member 5246 connected to the transmission screw 5244 converts the rotational motion of the transmission screw 5244 into a linear motion, the connecting member 5246 is matched with the first moving member 140 (the second moving member 160) to drive the second carrier 200 to move together, and the first moving member 140 and the second moving member 160 drive the second inserting portion 210 and the limiting member 220 mounted on the second carrier 200 to move when moving. In the process of moving the second carrier 200, the limiting member 220 pushes the flexible screen assembly 300 to move outward, i.e. the flexible screen assembly 300 is unfolded. When the driving of the first driving module 5222 is reversed, the first moving element 140 and the second moving element 160 move to drive the first carrier 100 and the second carrier 200 to move toward each other, at this time, the first plugging portion 110 disposed on the first carrier 100 moves toward the direction close to the limiting element 220, and the connecting element 5246 disposed on the driving screw 5244 moves away from the limiting element 220, and the two moving speeds are the same and the directions are opposite. The first driving belt 420 connected to the first moving member 140 and the second driving belt 440 connected to the second moving member 160 respectively switch the moving direction through the roller 180, and pull the supporting piece 340 in the flexible screen assembly 300, so that the moving speed of the supporting piece 340 in the flexible screen assembly 300 in the direction away from the limiting member 220 is the same as the moving speed of the first inserting part 110 in the direction close to the limiting member 220, and when the first moving member 140 and the second moving member 160 are folded to the first preset position, the flexible screen 320 is also brought to the second preset position by the supporting piece 340, thereby implementing the folding function of the flexible screen assembly 300.

It should be noted that the number of the moving elements may be one, and the number of the transmission belts may also be one, for example, one side of the second carrier 200 is provided with the first moving element 140, and the other side of the second carrier 200 is not provided with the moving element. The first mover 140 is connected to the first belt 420, and the structure and connection relationship with other structures of the first mover 140 and the structure and connection relationship with other structures of the first belt 420 are as described above. When the first moving member 140 moves to drive the first and

second carriers

100 and 200 to move in a direction to approach each other, the first driving belt 420 moves around the first moving member 140 to pull the flexible screen assembly 300 to move.

One end of the second protrusion 740 is disposed adjacent to the first driving module 5422 of the second driving mechanism 540 and the height of the first driving module 5422 is greater than that of the second protrusion 740, so as to reserve a space in the second protrusion 740 for mounting other devices (such as a semiconductor, a capacitor, or a resistor) of the electronic apparatus 20. A portion of the battery 600 is located between the first and

second protrusions

720 and 740, and another portion of the battery 600 is located between the first and
