The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1 to 5, an embodiment of the present application discloses an electronic apparatus including an apparatus main body 100, a winding shaft 200, a flexible display 300, and a first driving mechanism 400.

The apparatus main body 100 is a base member of the electronic apparatus, and the apparatus main body 100 can provide a mounting base for other constituent members of the electronic apparatus.

The winding shaft 200 is rotatably provided in the apparatus main body 100, that is, the winding shaft 200 can rotate with respect to the apparatus main body 100.

The flexible display 300 has a first end and a second end, and at least one of the first end and the second end is connected to the winding shaft 200, that is, the winding shaft 200 may be connected to the first end of the flexible display 300 or may be connected to the second end of the flexible display 300, and if the number of winding shafts 200 is at least two, different winding shafts 200 may be connected to the first end and the second end of the flexible display 300 respectively, and the connection manner may include bonding, etc., which is not limited in this embodiment of the present application, and the flexible display 300 may be at least partially wound around the winding shaft 200. It should be noted that, in any of the above arrangements of the flexible display 300 and the winding shaft 200, when a user needs to expand the display of the electronic device, the winding shaft 200 may be rotated to separate the portion of the flexible display 300 wound on the winding shaft 200 from the winding shaft 200, so that the distance between the first end and the second end of the flexible display 300 is increased, and thus the display area of the electronic device is increased, so as to meet the user requirement; when the use is completed, the winding shaft 200 may be reversely rotated so that more part of the flexible display 300 is wound around 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 crease lines of the flexible display screen 300 can be avoided, and the use experience of a user is improved.

The first driving mechanism 400 includes a driving source 410, and the driving source 410 may be a motor, a hydraulic cylinder, or the like, and the embodiment of the present application is not particularly limited. The driving source 410 is connected to at least one of the first end and the second end, the driving source 410 drives the flexible display screen 300 to switch between an expanded state and a contracted state, the driving source 410 is provided with an output shaft, and an extending direction of the output shaft is parallel to an extending direction of the winding shaft 200, wherein in the expanded state, a 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 driving source 410 is connected to the first end of the flexible display screen 300, when a user needs to expand the display screen of the electronic device, the driving source 410 acts on the first end of the flexible display screen 300, and at this time, since the second end of the flexible display screen 300 is connected to the winding shaft 200, the winding shaft 200 rotates with respect to the device main body 100, so that the portion of the second end of the flexible display screen 300 wound on the winding shaft 200 is separated from the winding shaft 200, i.e., the distance between the first end and the second end of the flexible display screen 300 becomes large; similarly, in the case where the driving source 410 is connected to the second end of the flexible display 300, when the user needs to expand the display of the electronic device, the driving source 410 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 main body 100, so that the portion of the first end of the flexible display 300 wound on the winding shaft 200 is separated from the winding shaft 200, i.e., 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 driving source 410 may be simultaneously connected with the first and second ends of the flexible display screen 300, and when a user needs to expand the display screen of the electronic device, the driving source 410 simultaneously acts on the first and second ends of the flexible display screen 300, so that the distance between the first and second ends of the flexible display screen 300 becomes larger, and at this time, the winding shafts 200 connected with the first and second ends of the flexible display screen 300 are rotated with respect to the device body 100, and the display area of the flexible display screen 300 increases. When the use is completed, the first end and/or the second end of the flexible display screen 300 may be manually pushed to reduce the distance between the first end and the second end of the flexible display screen 300, and the winding shaft 200 may be reversely rotated at this time, so that the display area of the flexible display screen 300 is reduced. It should be noted that, in the embodiment of the present application, if the extending direction of the output shaft of the driving source 410 has a certain included angle with the extending direction of the winding shaft 200, when the driving source 410 drives the first end and the second end of the flexible display screen 300 to move, the first end and the second end of the flexible display screen 300 may incline, so that the surface of the flexible display screen 300 may be wrinkled; secondly, the extending direction of the output shaft of the driving source 410 and the extending direction of the winding shaft 200 have a certain included angle, which occupies a larger space, is unfavorable for the arrangement of the driving source 410 and increases the design difficulty. Therefore, optionally, the extending direction of the output shaft of the driving source 410 is parallel to the extending direction of the winding shaft 200, so that the surface of the flexible display screen 300 can be ensured to be flat, the use experience of a user can be improved, the utilization rate of the space in the device main body can be improved, the arrangement of the driving source 410 is facilitated, and the design difficulty is reduced.

In the embodiment of the application, the driving source 410 can drive the flexible display screen 300 to switch between an expanded state and a contracted state, and in the expanded state, the display area of the flexible display screen 300 is larger, so that the use requirement of a user on the large-screen electronic equipment can be met; in the contracted state, the display area of the flexible display screen 300 is smaller, and accordingly, the overall size of the electronic device is smaller, so that the electronic device is convenient for a user to operate on the basis of meeting the basic use requirement of the user on the electronic device, and secondly, the electronic device with the smaller size can be conveniently carried by the user. Therefore, the electronic equipment disclosed by the embodiment of the application can solve the problems of inconvenient operation and poor portability caused by the large size of the current electronic equipment.

In an alternative embodiment, the device main body 100 includes a first housing 110 and a second housing 120, where the first housing 110 and the second housing 120 can each provide a mounting base for other components of the electronic device, a first end of the flexible display screen 300 is connected to the first housing 110, and a second end of the flexible display screen 300 is connected to the second housing 120, where the connection manners may all adopt various manners such as bonding, and the embodiment of the application is not limited specifically. The driving source 410 may drive the first end of the flexible display 300 to move through the first housing 110, in which case, the winding shaft 200 is disposed in the first housing 110, and 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 driving source 410 drives the first housing 110 to move, and the first housing 110 will drive the first end of the flexible display 300 to move, so that the distance between the first end and the second end of the flexible display 300 becomes larger; similarly, the driving source 410 may also drive the second end of the flexible display screen 300 to move through the second housing 120, in which 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 driving source 410 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 becomes larger; when the number of the winding shafts 200 is at least two, the driving source 410 may simultaneously drive the first and second ends of the flexible display screen 300 through the first and second housings 110 and 120, and in this case, the driving source 410 may simultaneously drive the first and second housings 110 and 120 so that the first and second housings 110 and 120 simultaneously drive the first and second ends of the flexible display screen 300 to move, and the distance between the first and second ends of the flexible display screen 300 becomes large. Therefore, in the embodiment of the present application, the first housing 110 and the second housing 120 not only can provide a mounting base for other components of the electronic device, but also can be used for protecting the structures arranged in the first housing 110 and the second housing 120, so as to reduce wear; secondly, the first housing 110 and the second housing 120 are connected to the first end and the second end of the flexible display screen 300, respectively, so that maintenance is facilitated after the first housing 110 or the second housing 120 is damaged by multiple uses.

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 vary with the distance between the first housing 110 and the second housing 120, and then, the structure such as the driving source 410 is disposed in the telescopic structure, so that the structure such as the driving source 410 can be prevented from being exposed to the outside and being worn.

That is, the first winding shaft 210 and the second winding shaft 220 are respectively provided in the first case 110 and the second case 120, and when the driving source 410 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 large while the first winding shaft 210 rotates with respect to the first case 110 and the second winding shaft 220 rotates with respect to the second case 120. Therefore, in the embodiment of the application, by setting a 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 easy to wrinkle, so that the use experience of a user is improved.

In an alternative embodiment, the driving source 410 is connected to both the first housing 110 and the second housing 120, and the driving source 410 drives the first housing 110 and the second housing 120 relatively far apart or relatively close together. Because the first end of the flexible display screen 300 is connected with the first housing 110, the second end of the flexible display screen 300 is connected with the second housing 120, when a user needs to use the large-screen electronic device, the driving source 410 drives the first housing 110 and the second housing 120 to move at the same time, so that the first housing 110 and the second housing 120 are relatively far away, and 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 at the moment; when the use is completed, the driving source 410 drives the first housing 110 and the second housing 120 to move in opposite directions at the same time, so that the first housing 110 and the second housing 120 are relatively close, and the first end and the second end of the flexible display 300 are relatively close under the driving of the first housing 110 and the second housing 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 driving source 410 may be used to drive the first and second ends of the flexible display screen 300, thereby improving the efficiency of the distance change between the first and second ends of the flexible display screen 300 and reducing the cost of the electronic device.

In the above embodiment, if the driving source 410 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 driving source 410 moves the first housing 110 and the second housing 120 a plurality of times. Optionally, the apparatus main body 100 further includes a first bracket 130 and a second bracket 140, one ends of the first bracket 130 and the second bracket 140 are fixedly connected with the first housing 110 and the second housing 120 respectively, the other ends are connected with the driving source 410, the driving source 410 drives the first bracket 130 and the second bracket 140 to move simultaneously, and accordingly, the first bracket 130 drives the first housing 110 to move, and the second bracket 140 drives the second housing 120 to move, so that the first bracket 130 and the second bracket 140 can protect the first housing 110 and the second housing 120, and prolong the service lives of the first housing 110 and the second housing 120.

In an alternative embodiment, the first driving mechanism 400 further includes a transmission mechanism 420, where 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 screen 300, that is, one end of the transmission mechanism 420 may be connected to the first end of the flexible display screen 300, may be connected to the second end of the flexible display screen 300, and may be connected to both the first end and the second end of the flexible display screen 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 screen 300 to switch between the expanded state and the contracted state through the transmission mechanism 420. Specifically, when the 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 is completed, the driving source 410 drives the transmission mechanism 420 to reversely move, 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 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, and 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.

Therefore, in the embodiment of the present application, the transmission mechanism 420 has the characteristics of compact structure and convenient operation.

If the drive source 410 rotates too fast, the drive mechanism 420 will operate less stably and wear of the drive mechanism 420 will be increased. Optionally, the transmission mechanism 420 further includes a speed reducer 424, one end of the speed reducer 424 is connected to the output shaft of the driving source 410, the other end is connected to the screw rod 423, and the speed reducer 424 has the characteristics of reducing the rotation speed and increasing the output torque, so that the speed reducer 424 can make the operation of the transmission mechanism 420 more stable, and slow down the wear of the transmission mechanism 420.

The driving source 410 drives the third end of each rotary push rod 421 to be relatively far away or relatively close to each other through the screw 423. Because the transmission mechanism 420 has the characteristics of reliable transmission, compact structure and high transmission efficiency, in the embodiment of the application, the number of the rotary push rod 421 and the moving member 422 is multiple, and these effects of the transmission mechanism 420 are further enhanced, so that the flexible display screen 300 is more stable and reliable when switching between the expanded state and the contracted state.

In a further alternative embodiment, the screw 423 includes a first threaded section 423a and a second threaded section 423b, the first threaded section 423a having a direction of rotation opposite to that of the second threaded section 423b, that is, the screw 423 is a bi-directional threaded screw, a portion of the moving member 422 is threadedly engaged with the first threaded section 423a, and another portion of the moving member 422 is threadedly engaged with the second threaded section 423 b.

Therefore, the screw 423 in the embodiment of the application adopts a bidirectional threaded screw, has the characteristics of simple structure and high transmission efficiency, and is beneficial to the arrangement of the transmission mechanism 420.

Optionally, each rotary push rod 421 forms at least one diamond linkage. Because the diamond-shaped link mechanism has the characteristics of simple structure, stability and low manufacturing cost, in the implementation of the application, at least one diamond-shaped link mechanism can enable the driving source 410 to drive the rotary push rod 421 to move through the screw 423, so that the rotary push rod 421 can move more stably and reliably, and the cost of electronic equipment can be reduced. Further, each rotary push rod 421 forms a plurality of diamond-shaped link mechanisms, thereby further improving the stability of the transmission mechanism.

In an alternative embodiment, when the apparatus main body 100 includes the first housing 110 and the second housing 120, the third end of the rotary push rod 421 is connected to the first housing 110 or the second housing 120, and the connection manner may be a fixed connection or a sliding connection, which is not limited in particular in the embodiment of the present application.

In other embodiments, the third end of the rotary push rod 421 is slidably connected to the first housing 110 or the second housing 120, specifically, a sliding groove may be formed on the first housing 110 or the second housing 120, and when the driving source 410 drives the rotary push rod 421 to move the first housing 110 or the second housing 120 through the screw rod 423, the rotary push rod 421 slides in the sliding groove of the first housing 110 or the second housing 129, so that the first end or the second end of the flexible display screen 300 can move more flexibly and conveniently in the moving process, and the rotary push rod 421 is prevented from being constrained by the first housing 110 or the second housing 120, thereby making the operation of the whole transmission mechanism 420 more stable and smooth.

Specifically, when the user needs to use the large-screen electronic device, the driving source 410 drives the two driving structures 420 to move together at the same time, the driving mechanism 420 connected with the first end of the flexible display screen 300 will drive the first end of the flexible display screen 300 to move, and the driving mechanism 420 connected with the second end of the flexible display screen 300 will drive 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, and the display area of the electronic device is increased; after the use is completed, the driving source 410 drives the two transmission mechanisms 420 to move reversely together, 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 transmission mechanisms 420, so that the display area of the electronic equipment is reduced. The embodiment of the application adopts a driving source 410 to realize bidirectional driving, so that the first end and the second end of the flexible display screen 300 move simultaneously, the changing efficiency of the display area of the flexible display screen 300 can be further improved, and the use experience of a user is improved.

Optionally, the electronic device disclosed in the embodiments of the present application further includes a second driving mechanism 500, where the second driving mechanism 500 is connected to the winding shaft 200, and the second driving mechanism 500 drives the winding shaft 200 to rotate, and the flexible display 300 is wound on the winding shaft 200 under the action of the second driving mechanism 500. Alternatively, the second driving mechanism 500 may have various structures such as a motor, a hydraulic cylinder, and the like, which is not particularly limited in the embodiment of the present application. When a user needs to use the large-screen electronic device, the driving source 410 applies a 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, thereby driving the first end and the second end of the flexible display screen 300 to move, and separating the portion of the flexible display screen 300 wound on the winding shaft 200 from the winding shaft 200, thereby making the distance between the first end and the second end of the flexible display screen 300 become larger. After the use is completed, the first end and the second end of the flexible display screen 300 may be manually pushed, or the driving source 410 reversely rotates to drive the distance between the first end and the second end of the flexible display screen 300 to be smaller, and the second driving mechanism 500 drives the winding shaft 200 to rotate, so that at least part of the flexible display screen 300 is wound on the winding shaft 200. Therefore, the second driving mechanism 500 in the embodiment of the present application can make the rotation of the winding shaft 200 more reliable and stable, so as to prevent the flexible display screen 300 from wrinkling when the distance between the first end and the second end thereof becomes smaller.

In an alternative embodiment, the second driving mechanism 500 includes a coil spring 510, the coil spring 510 being provided in the apparatus body 100, one end of the coil spring 510 being connected to the winding shaft 200, and the other end of the coil spring 510 being fixed with respect to the apparatus body 100. When the driving source 410 acts on the first end or the second end of the flexible display screen 300, the coil spring 510 is deformed when the distance between the first end and the second end of the flexible display screen 300 becomes large; when the distance between the first end and the second end of the flexible display screen 300 becomes smaller, the coil spring 510 resumes the deformation, thereby winding around the flexible display screen 300, preventing the flexible display screen 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.

In the above embodiment, if the coil spring 510 is directly connected to the apparatus main body 100, since the coil spring 510 is wrapped by the winding shaft 200, the coil spring 510 can be connected only to the side wall of the apparatus main body 100, the connection area is limited, and the connection strength is not high. Therefore, alternatively, the second driving mechanism 500 may further include a connection shaft 520, the connection shaft 520 being connected to one end of the coil spring 510, and the connection shaft 520 being fixed to the apparatus body 100, the connection shaft 520 being also wrapped by the winding shaft 200, and an extending direction of the connection shaft 520 may be parallel to an extending direction of the winding shaft 200, so that a connection area of the coil spring 510 and the connection shaft 520 may be set larger, thereby improving a connection strength of the coil spring 510 and the apparatus body 100.

In another alternative embodiment, the second driving mechanism 500 includes a piezoelectric ceramic member disposed in the apparatus body 100, the piezoelectric ceramic member being connected to one end of the winding shaft 200, and the piezoelectric ceramic member driving the winding shaft 200 to rotate when the piezoelectric ceramic member is energized. When the driving source 410 acts on the first end or the second end of the flexible display screen 300, the piezoelectric ceramic member is energized to rotate the winding shaft 200 so that the distance between the first end and the second end of the flexible display screen 300 becomes large; when the distance between the first end and the second end of the flexible display screen 300 becomes smaller, the piezoelectric ceramic member is electrified with a reverse current, so that the winding shaft 200 is driven to reversely rotate, and thus the flexible display screen 300 is wound, and the flexible display screen 300 is prevented from being wrinkled. Because the piezoelectric ceramic piece has the characteristics of small size, long service life and good stability, compared with the mode of adopting the coil spring 510 to drive in the embodiment, the piezoelectric ceramic piece is adopted to drive the flexible display screen 300 to move in the embodiment of the application, so that the space in the equipment main body 100 can be saved, the size of the electronic equipment is smaller, the movement of the flexible display screen 300 is more stable, and the service life of the electronic equipment is prolonged.

The electronic device disclosed in the embodiments of the present application may be an electronic device such as a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), an electronic game machine, etc., and the types of the electronic device are not particularly limited in the embodiments of the present application.

The embodiments of the present application have been described above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and many forms may be made by those of ordinary skill in the art without departing from the spirit of the present application and the scope of the claims, which are also within the protection of the present application.
