In the embodiment, the flexible screen 22 can be stored by using the scroll 21, and when the screen needs to be expanded, a part of the flexible screen 22 stored on the scroll 21 is pulled out by the driving assembly 30 to expand the screen display area of the electronic device; when the screen display area needs to be reduced, the driving assembly 30 can drive the flexible screen 22 to move, so that the extra flexible screen 22 is accommodated on the reel 21, and the flexible screen 22 of the electronic device is switched between the first screen state and the second screen state. Moreover, as the extra flexible screen 22 can be stored on the scroll 21, the flexible screen 22 moves along the circumferential surface of the scroll 21 during the state switching process, compared with the inward-folding flexible screen, the bending radius of the flexible screen during the movement can be increased, the phenomenon that the flexible screen is dented, i.e. folded, can be reduced, the fatigue wear degree of the flexible screen during the state switching process can be reduced, and the purpose of improving the display effect of the flexible screen can be achieved.

In the present application, the first frame 11 is sleeved on the second frame 12, and may be embodied as an embedded sleeve, that is, the first frame 11 is disposed inside the second frame 12, and the second frame 12 can slide relative to the first frame 11.

In the above description, the first screen state is that the flexible screen of the electronic device is in a non-expanded state, and the second screen state is that the flexible screen of the electronic device is in an expanded state, and the flexible screen 22 can be switched from the non-expanded state to the expanded state, so as to increase the screen display area of the electronic device, and make the electronic device have a wide-screen or large-screen display effect.

Moreover, compared with the electronic equipment with the folding screen, the electronic equipment with the folding screen has the advantages that by adopting the scheme of the electronic equipment, parts such as folding components of the electronic equipment with the folding screen can be saved, and the overall weight of the electronic equipment can be reduced.

In an embodiment, one end of the flexible screen 22 may be wound on the reel 21, and the other end is directly connected to the first frame 11, for example, if the end connected to the reel 21 is a head end and the end connected to the first frame 11 is a tail end, the flexible screen 22 includes, from the head end, a first portion wound on the reel 21, a second portion wound around the rear cover assembly 40 of the electronic device, a third portion wound around the second frame 22, and a fourth portion covering the first frame 21.

In another embodiment, both ends of the flexible screen 22 are wound on the reels 21, i.e. both the head end and the tail end are connected to the reels 21. In the winding process, the flexible screen on the display surface side and the flexible screen on the rear cover assembly 40 side are simultaneously wound, as shown in fig. 2. Specifically, the first frame 11 has a first through hole and a second through hole, which are respectively provided on two opposite surfaces of the first frame 11. One end of the flexible screen is wound on the reel, one end of the flexible screen extends out of the first through hole, and the flexible screen extends into the second through hole and is connected with the reel after surrounding the second frame body.

In some embodiments, in the process of switching the flexible screen 22 from the first screen state to the second screen state, the portion of the flexible screen 22 disposed to cover the first frame body 11 in the first screen state follows the movement of the second frame body 12; after switching to the second screen state, the flexible screen originally provided to cover the first frame 11 is provided to cover the second frame 12, and a part of the flexible screen stored in the reel is extracted to cover the first frame 11, thereby expanding the screen display area of the flexible screen 22.

In some embodiments, a sliding structure may be provided between the first frame body 11 and the second frame body 12 to realize the sliding connection of the first frame body 11 and the second frame body 12. For example, a slide rail may be disposed on the first frame 11, a slide block may be disposed on the second frame 12, and the slide rail and the slide block are connected in a fitting manner, so as to realize the sliding connection between the first frame 11 and the second frame 12; correspondingly, a slide block may be disposed on the first frame 11, and a slide rail may be disposed on the second frame 12, so as to realize the sliding connection between the first frame 11 and the second frame 12.

In other embodiments, a driving force may be applied to the second frame body 12 through a driving structure to realize the sliding of the second frame body 12 relative to the first frame body 11; in the present embodiment, the sliding of the second housing 12 with respect to the first housing 11 is synchronized with the movement of the flexible screen 22. For example, the second frame 12 and the flexible screen 22 may be respectively driven by two sets of driving structures, and both sets of driving structures are electrically connected to a processor of the electronic device, and the two sets of driving structures are controlled by the processor, so as to synchronously drive the first frame 11 and the flexible screen 22.

In addition, the driving assembly 30 may also be connected to the second frame 12, and can drive the second frame 12 to move, so as to drive the flexible screen 22 to move, and enable the flexible screen 22 to switch between the first screen state and the second screen state.

Optionally, the drive assembly 30 includes a motor 31, a crank linkage, a guide rail 35, and a bracket 36; the crank link mechanism comprises a first link 32, a second link 33, a slider 34 and an output shaft (not shown) of the motor 31, wherein the first end of the first link 32 is movably connected with the output shaft of the motor 31, the second end of the first link 32 is movably connected with the first end of the second link 33, the second end of the second link 33 is movably connected with the slider 34, the slider 34 is slidably connected with a guide rail 35, and the slider 34 is connected with the flexible screen 22 through a bracket 36; the output shaft, the first connecting rod 32, the second connecting rod 33 and the slide block 34 form a crank connecting rod mechanism.

In the present embodiment, the driving of the flexible screen 22 by the motor 31 can be realized by using a crank link mechanism composed of an output shaft, the first link 32, the second link 33, and the slider 34; moreover, the crank-link mechanism has a limit position, so that the movement range of the flexible screen 22 can be limited through the limit position of the crank-link mechanism; compared with other transmission mechanisms which need to be provided with additional auxiliary mechanisms for limiting the movement range of the flexible screen 22, the installation space required by the driving assembly 30 can be effectively saved.

For example, when the crank linkage is moved to a first extreme position, the flexible screen 22 may be set in a first screen state; when the crank linkage is moved to the second extreme position, the flexible screen 22 may be placed in the second screen state. Wherein, in the first extreme position, the display area of the screen portion of the flexible screen 22 for display is at a minimum; and in the second extreme position the display area of the screen portion of the flexible screen 22 for display is at a maximum.

Furthermore, a first limit structure may be disposed at the first limit position to limit the movement of the crank link mechanism at the first limit position, so as to lock the flexible screen 22 in the first screen state, so as to maintain the stability of the display effect of the flexible screen 22 in the first screen state; correspondingly, a second limit structure can be arranged at the second limit position to display that the crank-link mechanism moves at the second limit position, so that the flexible screen 22 is locked in the second screen state, and the stability of the display effect of the flexible screen 22 in the second screen state is maintained.

The first limiting structure and the second limiting structure can be of a locking structure, and when the crank link mechanism moves to the first limiting structure or the second limiting structure, the locking structure can lock the first link 32 to limit the first link 32 to move continuously; the locking force of the locking structure to the first connecting rod 32 is greater than the rated driving force of the motor 31 to the first connecting rod 32; when the first link 32 needs to be driven to move continuously, the driving force of the motor 31 on the first link 32 can be increased, or the locking force of the locking structure on the first link 32 can be reduced.

Specifically, the first connecting rod 32 may be a magnetic connecting rod, the first limiting structure may be a first electromagnet 371, and the second limiting structure may be a second electromagnet 372; under the condition that the crank link mechanism moves to the first limit position, the first electromagnet 371 applies magnetic adsorption force to the first connecting rod 32 to limit the movement of the first connecting rod 32 at the first limit position; in the case where the crank link mechanism moves to the second limit position, the movement of the first link 32 at the second limit position is restricted by the magnetic attraction force exerted on the first link 32 by the second electromagnet 372.

In the case that the flexible screen 22 needs to be switched from the first screen state to the second screen state, the current of the first electromagnet 371 may be interrupted to reduce the magnetic attraction of the first electromagnet 371 on the first link 32, so that the motor 31 drives the first link 32 to move to the second limit position; furthermore, it is also possible to reduce the driving force required to be provided by the motor 31 and reduce the power consumption required by the motor 31 by applying a reverse current to the first electromagnet 371 so that the first electromagnet 371 applies a repulsive force to the first link 32.

Accordingly, in the case that the flexible screen 22 needs to be switched from the second screen state to the first screen state, the magnetic attraction force of the second electromagnet 372 on the first link 32 can be reduced by interrupting the current of the second electromagnet 372, so that the motor 31 drives the first link 32 to move to the first limit position; furthermore, the driving force required to be provided by the motor 31 can be reduced and the energy consumption required by the motor 31 can be reduced by applying a reverse current to the second electromagnet 372 so that the second electromagnet 372 applies a repulsive force to the first link 32.

Optionally, the driving assembly 30 further includes an elastic member 38, one end of the elastic member 38 is connected to the slider 34, and the other end is connected to a baffle 39, and the baffle 39 is disposed at the end of the guide rail 35;

wherein, in the first screen state, the elastic member 38 is in one of a tension state and a compression state; in the second screen state, the elastic member 38 is in the other of the stretched state or the compressed state.

In this embodiment, by the arrangement of the elastic member 38, it is possible to improve the buffer provided for the movement of the flexible screen 22 and improve the stability of the movement of the flexible screen 22; moreover, in the first limit position or the second limit position, the elastic force provided by the elastic member 38 can assist the motor 31 to drive the first link 32 to move, so as to reduce the driving force required by the motor 31 to drive the first link 32, and further reduce the energy consumption required by the motor 31.
