It should be noted that no matter which setting mode is adopted between the flexible display screen 300 and the winding shaft 200, when a user needs to expand the display screen of the electronic device, the winding shaft 200 may be rotated to separate the portion of the flexible display screen 300 wound on the winding shaft 200 from the winding shaft 200, so that the distance between the first end and the second end is increased, and the display area of the electronic device is increased to meet the user requirement; when the use is completed, the winding shaft 200 may be rotated reversely to wind more parts of the flexible display 300 on the winding shaft 200, and at this time, the distance between the first end and the second end of the flexible display 300 becomes smaller, so that the display area of the electronic device becomes smaller. Secondly, at least part of the flexible display screen 300 is wound on the winding shaft 200, so that the flexible display screen 300 can be prevented from being folded, and the user experience is improved.

The first driving mechanism 400 is connected to at least one of the first end and the second end, and the first driving mechanism 400 drives the flexible display screen 300 to switch between an expanded state and a contracted state, wherein in the expanded state, the distance between the first end and the second end is a first distance; in the contracted state, the distance between the first end and the second end is a second distance, and the first distance is greater than the second distance. Specifically, in the case where the first driving mechanism 400 is connected to the first end of the flexible display 300, when a user needs to expand the display of the electronic device, the first driving mechanism 400 acts on the first end of the flexible display 300, and at this time, since the second end of the flexible display 300 is connected to the winding shaft 200, the winding shaft 200 rotates relative to the device body 100, so that the portion of the flexible display 300 wound around the winding shaft 200 is separated from the winding shaft 200, that is, the distance between the first end and the second end of the flexible display 300 becomes large; similarly, in the case that the first driving mechanism 400 is connected to the second end of the flexible display 300, when the user needs to expand the display of the electronic device, the first driving mechanism 400 acts on the second end of the flexible display 300, and at this time, since the first end of the flexible display 300 is connected to the winding shaft 200, the winding shaft 200 rotates relative to the device body 100, so that the portion of the first end of the flexible display 300 wound around the winding shaft 200 is separated from the winding shaft 200, that is, the distance between the first end and the second end of the flexible display 300 becomes larger; when the number of the winding shafts 200 is at least two, the first driving mechanism 400 may be connected to the first end and the second end of the flexible display 300 at the same time, and when a user needs to expand the display of the electronic device, the first driving mechanism 400 acts on the first end and the second end of the flexible display 300 at the same time, so that the distance between the first end and the second end of the flexible display 300 is increased, and at this time, the winding shafts 200 connected to the first end and the second end of the flexible display 300 rotate relative to the device main body 100, so that the display area of the flexible display 300 is increased. After the use is completed, the first end and/or the second end of the flexible display 300 can be manually pushed, so that the distance between the first end and the second end of the flexible display 300 is reduced, and at this time, the winding shaft 200 can reversely rotate, so that the display area of the flexible display 300 is reduced.

In the embodiment of the present application, the first driving mechanism 400 may drive the flexible display 300 to switch between the expanded state and the contracted state, and in the expanded state, the display area of the flexible display 300 is large, which may meet the user requirement of the large-screen electronic device; in the contracted state, the display area of the flexible display screen 300 is small, and accordingly the overall size of the electronic device is small, so that the electronic device is convenient for a user to operate on the basis of meeting the basic use requirements of the user on the electronic device, and the electronic device with the small size can be conveniently carried by the user. Therefore, the electronic equipment disclosed by the application can solve the problems of inconvenient operation and poor portability caused by the large size of the conventional electronic equipment.

In an alternative embodiment, the device main body 100 includes a first housing 110 and a second housing 120, the first housing 110 and the second housing 120 may both provide a mounting base for other components of the electronic device, a first end of the flexible display 300 is connected to the first housing 110, a second end of the flexible display 300 is connected to the second housing 120, and the connection manner may be various bonding, and the embodiment of the present invention is not limited in particular. The first driving mechanism 400 can drive the first end of the flexible display screen 300 to move through the first housing 110, in this case, the winding shaft 200 is disposed in the first housing 110, since the winding shaft 200 can rotate relative to the apparatus main body 100, the winding shaft 200 can also rotate relative to the first housing 110, the first driving mechanism 400 drives the first housing 110 to move, the first housing 110 will drive the first end of the flexible display screen 300 to move, and the distance between the first end and the second end of the flexible display screen 300 becomes larger; similarly, the first driving mechanism 400 may also drive the second end of the flexible display screen 300 to move through the second housing 120, in this case, the winding shaft 200 is disposed in the second housing 120, the winding shaft 200 can rotate relative to the second housing 120, the first driving mechanism 400 drives the second housing 120 to move, and the second housing 120 drives the second end of the flexible display screen 300 to move, so that the distance between the first end and the second end of the flexible display screen 300 is increased; when the number of the winding shafts 200 is at least two, the first driving mechanism 400 may simultaneously drive the first end and the second end of the flexible display screen 300 to move through the first housing 110 and the second housing 120, in this case, the first driving mechanism 400 may simultaneously drive the first housing 110 and the second housing 120 to move, so that the first housing 110 and the second housing 120 simultaneously drive the first end and the second end of the flexible display screen 300 to move, and the distance between the first end and the second end of the flexible display screen 300 is increased. Therefore, in the embodiment of the present application, the first housing 110 and the second housing 120 may not only provide a mounting base for other components of the electronic device, but also protect structures disposed in the first housing 110 and the second housing 120, thereby reducing wear.

It should be noted that, in the embodiment of the present application, a telescopic structure with a variable size may be disposed between the first housing 110 and the second housing 120, and the size of the telescopic structure may be changed according to the distance between the first housing 110 and the second housing 120, and secondly, the first driving mechanism 400 and other structures are disposed in the telescopic structure, so that the first driving mechanism 400 and other structures can be prevented from being exposed to the outside and being worn.

In a further alternative embodiment, the number of the winding shafts 200 is at least two, and the winding shafts include a first winding shaft 210 and a second winding shaft 220, the first winding shaft 210 is disposed in the first casing 110, the second winding shaft 220 is disposed in the second casing 120, a first end of the winding shaft can be wound around the first winding shaft 210, and a second end of the winding shaft can be wound around the second winding shaft 220. That is, the first winding shaft 210 and the second winding shaft 220 are respectively disposed in the first housing 110 and the second housing 120, and when the first driving mechanism 400 simultaneously drives the first end and the second end of the flexible display 300 to move, the distance between the first end of the flexible display 300 and the second end of the flexible display 300 becomes larger, and simultaneously the first winding shaft 210 rotates relative to the first housing 110 and the second winding shaft 220 rotates relative to the second housing 120. Therefore, in the embodiment of the present application, by providing the plurality of winding shafts 200, the display area of the flexible display screen 300 changes more rapidly, and the flexible display screen 300 is not prone to wrinkle, so as to improve the user experience.

In an alternative embodiment, the first driving mechanism 400 is connected to both the first housing 110 and the second housing 120, and the first driving mechanism 400 drives the first housing 110 and the second housing 120 relatively far away or relatively close to each other. Because the first end of the flexible display screen 300 is connected to the first housing 110 and the second end of the flexible display screen 300 is connected to the second housing 120, when a user needs to use the large-screen electronic device, the first driving mechanism 400 simultaneously drives the first housing 110 and the second housing 120 to move, so that the first housing 110 and the second housing 120 are relatively far away, and thus the first end and the second end of the flexible display screen 300 are relatively far away under the driving of the first housing 110 and the second housing 120, and the display area of the electronic device is enlarged; after the electronic device is used, the first driving mechanism 400 drives the first casing 110 and the second casing 120 to move in opposite directions at the same time, so that the first casing 110 and the second casing 120 are relatively close to each other, and the first end and the second end of the flexible display screen 300 are relatively close to each other under the driving of the first casing 110 and the second casing 120, at this time, the display area of the electronic device is reduced, and the overall size of the electronic device is smaller. Therefore, in the embodiment of the present application, only one first driving mechanism 400 may be used to drive the first end and the second end of the flexible display 300, so that the efficiency of distance change between the first end and the second end of the flexible display 300 may be improved, and the cost of the electronic device may be reduced.

In the above embodiment, if the first driving mechanism 400 is directly connected to the first housing 110 and the second housing 120, the first housing 110 and the second housing 120 may be damaged after the first driving mechanism 400 drives the first housing 110 and the second housing 120 to move for a plurality of times. Optionally, the device main body 100 further includes a first bracket 130 and a second bracket 140, one end of each of the first bracket 130 and the second bracket 140 is respectively and fixedly connected to the first casing 110 and the second casing 120, and the other end of each of the first bracket 130 and the second bracket 140 is connected to the first driving mechanism 400, the first driving mechanism 400 drives the first bracket 130 and the second bracket 140 to move simultaneously, accordingly, the first bracket 130 drives the first casing 110 to move, and the second bracket 140 drives the second casing 120 to move, so that the first bracket 130 and the second bracket 140 can protect the first casing 110 and the second casing 120, and the service life of the first casing 110 and the second casing 120 is prolonged.

In an alternative embodiment, the first driving mechanism 400 includes a driving source 410 and a transmission mechanism 420, and the driving source 410 may be a motor, a hydraulic cylinder, or other structures, and the embodiments of the present application are not particularly limited. One end of the transmission mechanism 420 is connected to at least one of the first end and the second end of the flexible display 300, that is, one end of the transmission mechanism 420 may be connected to the first end of the flexible display 300, the second end of the flexible display 300, or both the first end and the second end of the flexible display 300. The other end of the transmission mechanism 420 is connected to the driving source 410, and the driving source 410 drives the flexible display panel 300 to switch between the extended state and the retracted state through the transmission mechanism 420. Specifically, when a user needs to use the large-screen electronic device, the driving source 410 drives the transmission mechanism 420 to move, and the transmission mechanism 420 drives the first end and/or the second end of the flexible display screen 300 to move, so that the distance between the first end and the second end of the flexible display screen 300 is increased, and the display area of the flexible display screen 300 is increased; after the use, the driving source 410 drives the transmission mechanism 420 to move in the opposite direction, and the distance between the first end and the second end of the flexible display screen 300 is reduced under the driving of the transmission mechanism 420, so that the overall size of the electronic device is reduced. Therefore, in the embodiment of the present application, the driving source 410 drives the first end and the second end of the flexible display screen 300 to move through the transmission mechanism 420, which has the characteristics of reliable transmission, compact structure and high transmission efficiency, so that the flexible display screen 300 is more reliable and stable in the moving process.

In a further optional embodiment, the transmission mechanism 420 includes a guide rod 421, a rotating push rod 422, and an elastic member 423, a third end of the rotating push rod 422 is in sliding fit with the guide rod 421, a fourth end of the rotating push rod 422 is connected to the first end or the second end, the elastic member 423 is sleeved on the guide rod 421, one end of the elastic member 423 is connected to the rotating push rod 422, the other end of the elastic member 423 is fixed relative to the guide rod 421, the driving source 410 drives the rotating push rod 422 to rotate, and the rotating push rod 422 drives the first end or the second end to move. Specifically, when a user needs to use the large-screen electronic device, the driving source 410 drives the rotating push rod 422 to rotate, and since one end of the elastic member 423 is connected to the rotating push rod 422, the rotating push rod 422 drives the elastic member 423 sleeved on the guide rod 421 to deform, and meanwhile, the rotating push rod 422 drives the first end or the second end of the flexible display screen 300 to move, so as to increase the display area of the flexible display screen 300; after the use is finished, the flexible display screen 300 can be manually pushed to be wound on the winding shaft 200, or the driving source 410 rotates reversely to drive the flexible display screen 300 to be wound on the winding shaft 200, so that the display area of the electronic device is reduced, and in the process, the elastic member 423 is restored to deform, so that the rotating push rod 422 is convenient to reset. Therefore, in the embodiment of the present application, the transmission mechanism 420 has the characteristics of simple structure and convenient operation.

Since the third end of the rotary push rod 422 is slidably engaged with the guide rod 421 and the fourth end of the rotary push rod 422 is connected to the first end or the second end of the flexible display panel 300, if the driving source 410 is directly connected to the rotary push rod 422, the driving source 410 can only be connected to the middle portion of the rotary push rod 422, and the connection of the driving source 410 and the rotary push rod 422 may obstruct the rotation of the rotary push rod 422, which increases the design difficulty. Therefore, in a further alternative embodiment, the transmission mechanism 420 further includes a pulling rope 424 and a pulley 425, the pulley 425 is fixed relative to the guiding rod 421, one end of the pulling rope 424 is connected to the driving source 410, the other end of the pulling rope 424 passes through the pulley 425 and is connected to the rotating push rod 422, and the driving source 410 drives the rotating push rod 422 to rotate through the pulling rope 424. Specifically, when the driving source 410 rotates, the pulling rope 424 is driven to move, and the pulling rope 424 drives the rotating push rod 422 to rotate, so that the rotating push rod 422 drives the first end or the second end of the flexible display screen 300 to move. Therefore, the transmission mechanism 420 facilitates the arrangement of the driving source 410 in the apparatus main body 100, and reduces the design difficulty.

The pulling rope 424 can be directly connected to the driving source 410, and in this case, in order to enable the pulling rope 424 to rotate the rotating push rod 422, the end of the pulling rope 424 connected to the driving source 410 must be moved, which requires a large space. Based on this, the transmission mechanism 420 further includes a rope winding shaft 426, the rope winding shaft 426 is coaxially connected to the driving source 410, and one end of the pulling rope 424 is wound around the rope winding shaft 426, so that the pulling rope 426 can transmit a force by rotation of the rope winding shaft 426 during switching between the extended state and the retracted state of the flexible display 300, and this way, a smaller space is required.

If the drive source 410 is rotating too fast, this may result in less stable operation of the gear train 420 and increased wear of the gear train 420. Optionally, the transmission mechanism 420 further comprises a speed reducer 427, one end of the speed reducer 427 is connected to the output shaft of the driving source 410, and the other end of the speed reducer 427 is connected to the rope winding shaft 426, and the speed reducer 427 has the characteristics of reducing the rotating speed and increasing the output torque, so that the arrangement of the speed reducer 427 can make the transmission mechanism 420 operate more stably and reduce the abrasion of the transmission mechanism 420.

In an alternative embodiment, the number of the rotating push rods 422 and the elastic members 423 is at least two, the third end of each rotating push rod 422 is connected to the first end or the second end, the fourth end of each rotating push rod 422 is slidably engaged with the guide rod 421, the driving source 410 drives the third end of each rotating push rod 422 to be relatively far away or relatively close, and each elastic member 423 is connected to each rotating push rod 422 in a one-to-one correspondence manner. Because the transmission mechanism 420 has the characteristics of reliable transmission, compact structure and high transmission efficiency, and in the embodiment of the present application, the number of the rotating push rods 422 and the number of the elastic members 423 are both multiple, these effects of the transmission mechanism 420 will be further enhanced, so that the flexible display screen 300 is more stable and reliable when being switched between the expanded state and the contracted state.

Since the flexible display 300 can be at least partially wound around the winding shaft 200, if the extending direction of the guiding rod 421 has a certain angle with the extending direction of the winding shaft 200, during the driving source 410 drives the flexible display 300 to switch between the extended state and the retracted state through the transmission mechanism 420, the first end and the second end of the flexible display 300 may be inclined, which may cause the flexible display 300 to have a crease, or even damage the flexible display 300; secondly, the extending direction of the guiding rod 421 and the extending direction of the winding shaft 200 have a certain angle, which is not beneficial to the arrangement of the transmission mechanism 420. Therefore, optionally, the extending direction of the guide bar 421 is parallel to the extending direction of the winding shaft 200, which can ensure that the flexible display screen 300 is kept flat and facilitate the arrangement of the transmission mechanism 420.

In an alternative embodiment, the number of the transmission mechanisms 420 is two, one of the transmission mechanisms 420 is connected to the first end of the flexible display panel 300, the other transmission mechanism 420 is connected to the second end of the flexible display panel 300, the two transmission mechanisms 420 are distributed on two sides of the driving source 410, the driving source 410 has a first output end and a second output end, and the first output end and the second output end are respectively connected to the two transmission mechanisms 420. Specifically, when a user needs to use the large-screen electronic device, the driving source 410 simultaneously drives the two transmission mechanisms 420 connected to the first output end and the second output end to move, the transmission mechanism 420 connected to the first end of the flexible display screen 300 drives the first end of the flexible display screen 300 to move, and the transmission mechanism 420 connected to the second end of the flexible display screen 300 drives the second end of the flexible display screen 300 to move, so that the first end and the second end of the flexible display screen 300 are relatively far away from each other, and the display area of the electronic device is increased; after the use, the driving source 410 drives the two transmission structures 420 connected to the first output end and the second output end to move in opposite directions, and the first end and the second end of the flexible display screen 300 are driven by the transmission structures 420 to be relatively close to each other, so that the display area of the electronic device is reduced. The embodiment of the application adopts a bidirectional driving mode, so that the first end and the second end of the flexible display screen 300 move simultaneously, the change efficiency of the display area of the flexible display screen 300 can be further improved, and the use experience of a user is improved.

It should be noted that, in the above embodiment, the axes of the first output end and the second output end of the driving source 410 may be located on the same straight line, and the extending directions of the first output end and the second output end are perpendicular to the extending direction of the winding shaft 200, which is favorable for the arrangement of the transmission mechanism 420 and can reduce the design difficulty.

Optionally, the electronic device disclosed in the embodiment of the present application further includes a second driving mechanism 500, the second driving mechanism 500 is connected to the winding shaft 200, the second driving mechanism 500 drives the winding shaft 200 to rotate, and the flexible display panel 300 is wound around the winding shaft 200 under the action of the second driving mechanism 500. Alternatively, the second driving mechanism 500 may be a motor, a hydraulic cylinder, or other structures, which is not particularly limited in this embodiment. When a user needs to use the large-screen electronic device, the first driving mechanism 400 applies an acting force to the first end and/or the second end of the flexible display screen 300, and at the same time, the second driving mechanism 500 drives the winding shaft 200 to rotate, so that the first end and the second end of the flexible display screen 300 are driven to move, the part of the flexible display screen 300 wound on the winding shaft 200 is separated from the winding shaft 200, and the distance between the first end and the second end of the flexible display screen 300 is increased. After the flexible display screen 300 is used, the first end and the second end of the flexible display screen 300 may be manually pushed, or the first driving mechanism 400 rotates in the opposite direction, which will drive the distance between the first end and the second end of the flexible display screen 300 to decrease, and at the same time, the second driving mechanism 500 will drive the winding shaft 200 to rotate, so that at least part of the flexible display screen 300 is wound around the winding shaft 200. Therefore, the second driving mechanism 500 is adopted in the embodiment of the present application, so that the rotation of the winding shaft 200 can be more reliable and stable, and the flexible display panel 300 can be prevented from being wrinkled when the distance between the first end and the second end of the flexible display panel is reduced.

In an alternative embodiment, the second driving mechanism 500 includes a coil spring 510, the coil spring 510 is disposed in the apparatus main body 100, one end of the coil spring 510 is connected to the winding shaft 200, and the other end of the coil spring 510 is fixed with respect to the apparatus main body 100. When the first driving mechanism 400 acts on the first end or the second end of the flexible display screen 300 to increase the distance between the first end and the second end of the flexible display screen 300, the coil spring 510 deforms; when the distance between the first end and the second end of the flexible display 300 becomes smaller, the coil spring 510 is restored to be deformed, thereby being wound around the flexible display 300, preventing the flexible display 300 from being wrinkled. Compared with the modes of motor driving, hydraulic cylinder driving and the like, the winding shaft 200 is driven to rotate by the coil spring 510 in the embodiment of the application, and the winding shaft has the characteristics of energy conservation, environmental protection and small occupied space.

Therefore, optionally, the second driving mechanism 500 further includes a connecting shaft 520, the connecting shaft 520 is connected to one end of the coil spring 510, and the connecting shaft 520 is fixed to the apparatus main body 100, the connecting shaft 520 is also wrapped by the winding shaft 200, and the extending direction of the connecting shaft 520 may be parallel to the extending direction of the winding shaft 200, so that the connecting area of the coil spring 510 and the connecting shaft 520 may be set large, thereby improving the connecting strength of the coil spring 510 and the apparatus main body 100.

In another alternative embodiment, the second driving mechanism 500 includes a piezoelectric ceramic element, which is disposed in the main body 100 and connected to one end of the winding shaft 200, and drives the winding shaft 200 to rotate when the piezoelectric ceramic element is energized. When the first driving mechanism 400 acts on the first end or the second end of the flexible display screen 300, the piezoelectric ceramic element is electrified to rotate the winding shaft 200, so that the distance between the first end and the second end of the flexible display screen 300 is increased; when the distance between the first end and the second end of the flexible display screen 300 is reduced, the piezoelectric ceramic piece is electrified with reverse current, so that the winding shaft 200 is driven to rotate reversely, the flexible display screen 300 is wound, and the flexible display screen 300 is prevented from being wrinkled. Because the piezoceramics has characteristics small, longe-lived and that stability is good, so, for the mode that adopts wind spring 510 drive in the above-mentioned embodiment, adopt piezoceramics drive flexible display screen 300 to move in this application embodiment, not only can save the space in the equipment main part 100, make electronic equipment's size littleer, can make flexible display screen 300's motion more stable moreover, prolong electronic equipment's life.
