As shown in FIG. 1 and FIG. 2 , an electronic device according to some embodiments of the present invention includes a first frame part 100 , a second frame part 102 and a flexible screen 104 .

The first frame part 100 has an accommodating space, and one side of the first frame part 100 is provided with an opening communicating with the accommodating space. The second frame part 102 is disposed in the accommodating space, and is telescopically connected with the first frame part 100 , that is, the second frame part 102 can expand and contract relative to the first frame part 100 . One side of the second frame part 102 is provided with a guide part 1120 .

The first part of the flexible screen 104 is fixed on the first frame part 100 . The second part of the flexible screen 104 is movably connected to the guide part 1120 on the second frame part 102 . The flexible screen 104 can expand or contract as the second frame part 102 expands and contracts relative to the first frame part 100 .

By setting the second frame part 102, and the second frame part 102 is telescopically arranged in the accommodating space of the first frame part 100, that is, the area of the electronic device can be expanded or reduced by expanding and contracting the second frame part 102. area of electronic equipment. At the same time, the first part of the flexible screen 104 is arranged on the first frame part 100, and the second part is movably connected with the second frame part 102, so that when the second frame part 102 stretches, the flexible screen 104 and the second frame part The second part connected with 102 will stretch or shrink along with the second frame part 102 .

When the second frame part 102 protrudes outward from the first frame part 100, the second part of the flexible screen 104 can expand along with the extension of the second frame part 102, which plays a role similar to that of a folding screen. effect, extending the screen on the front of the electronic device.

When the second frame part 102 is retracted inwardly from the first frame part 100, the second part of the flexible screen 104 can be curled together with the retraction of the second frame part 102, which has an effect similar to that of a folding screen. Both the front and back of the electronic device can be displayed.

Since the flexible screen 104 is curled rather than folded when the second frame part 102 is shrunk inwardly, there is no problem of whitening at half-folds caused by multiple folds and affecting screen display. Similarly, since the flexible screen 104 is curled and folded, it can be stretched and folded repeatedly, and there is no problem of shortened service life.

With the second frame part 102 driving the flexible screen 104 to curl and fold, since the screen does not increase the thickness of the electronic device after being folded, compared with the structural form of the folding screen, its thickness is smaller and it is more convenient to hold. There is no need to arrange hinges on the flexible screen 104, and it does not occupy the space of other components on the electronic device.

It should be pointed out that the first part of the flexible screen 104 is fixedly arranged on the first frame part 100, the second part is movably connected with the second frame part 102, and the second frame part 102 can move relative to the first frame part 100. Therefore, the first part of the flexible screen 104 is always fixed relative to the first frame part 100 . The first part of the flexible screen 104 that does not move relative to the first frame part 100 can be understood as the front screen of the electronic device. Correspondingly, the second part of the flexible screen 104 that moves with the second frame part 102 , or in other words, the part of the flexible screen 104 that moves relative to the first frame part 100 , can be understood as the back screen of the electronic device. When the second frame part 102 stretches out to the first frame part 100 and expands, the back screen can be located on the same plane with the front screen along with the second frame part 102 expanding; When the first frame part 100 is retracted and folded, the originally flat flexible screen 104 bends to roughly form two opposite screens, that is, the front screen of the electronic device and the back screen of the electronic device are formed. part, and the flexible screen 104 between these two opposite parts is curved, and there is no trace of folding.

As shown in FIGS. 8 and 16 , it can be understood that the second frame portion 102 has a front side and a back side. The front side is the side located in the front, and the back side is the side located in the back. In some possible applications, only the back side is provided with the guide portion 1120 . After the second part of the flexible screen 104 slides to the front side, it will break away from the guide part 1120 .

In some other possible applications, both the front side and the back side are provided with the guide part 1120 , then the second part of the flexible screen 104 still slides along the guide part 1120 after sliding to the front side.

As shown in FIG. 16 , in some embodiments, the guide portion 1120 may be in the shape of a groove, or in other words, the guide portion 1120 is a guide groove. The edge of the second part of the flexible screen 104 is disposed in the guide groove and slides along the guide groove.

In some other embodiments, the guide part 1120 may be in the shape of a protruding guide rail, and the second part of the flexible screen 104 is connected to the guide rail through hinges, hooks and other components.

According to some embodiments of the present invention, a slideway is provided on the first frame part 100 , and the second frame part 102 slides relative to the first frame part 100 along the slideway. The second frame part 102 can be manually driven, that is, the user manually pulls the second frame part 102 out of the first frame part 100 , so that the flexible screen 104 stretches as the second frame part 102 stretches out. Alternatively, the user manually pushes the second frame part 102 into the first frame part 100 so that the flexible screen 104 is retracted as the second frame part 102 is retracted.

In some other embodiments, the second frame part 102 is provided with rollers. When the user pulls out or pushes in the second frame part 102 manually, the setting of the rollers can reduce friction and improve the smoothness of the second frame part 102 moving.

It should be noted that, for the way in which the user manually drives the second frame part 102 to expand and contract, it is necessary to provide a mutually cooperative limiting structure on the second frame part 102 and the first frame part 100 . For example, on the first frame part 100, some protrusions protruding toward the second frame part 102 are set. Being pulled out of the first frame part 100 is beneficial to improving the stability and reliability of the electronic equipment.

According to other embodiments of the present invention, the electronic device further includes a driving device 106 . The expansion and contraction of the second frame part 102 is realized by the driving device 106 . Using the driving device 106 to drive the second frame part 102 is beneficial to realize automatic control of the expansion and contraction of the second frame part 102 . In this manner, the moving distance of the second frame part 102 can be precisely controlled, and the convenience and comfort of the user in using the electronic device can be improved. In the way of driving by the driving device 106 , the moving distance can be specifically controlled by means of the running time of the driving device 106 , the number of turns of the running, and the like. Moreover, the driving device 106 is adopted, and its driving force is more stable and appropriate than the manual method, which is beneficial to avoid violent driving, thereby improving the stability and reliability of the electronic equipment.

Specifically, a driving device 106 is provided on the first frame part 100 or the second frame part 102 . The driving device 106 realizes the telescopic movement of the second frame part 102 by pushing the second frame part 102 .

According to some embodiments of the present invention, the driving device 106 is directly installed on the second frame part 102 . For example, the driving device 106 includes a motor and a roller, and the roller is rotatably connected to the second frame part 102 through a rotating shaft. The motor drives the rollers to rotate, and the rollers drive the second frame part 102 to extend out of the first frame part 100 , or drive the second frame part 102 to retract into the first frame part 100 . It can be understood that the rollers move together with the second frame part 102 . Correspondingly, in this embodiment, it is generally necessary to set a limit structure on the second frame part 102 or the first frame part 100, for example, set a limit boss on the first frame part 100 to prevent the second frame part 102 from falling out. The first frame part 100.

According to still other embodiments of the present invention, the driving device 106 includes an electric cylinder or a linear motor. Both are retractable devices that can be powered by electricity. One end of the electric cylinder or linear motor is connected to the first frame part 100 , and the other end of the electric cylinder or linear motor is connected to the second frame part 102 . When the electric cylinder or the linear motor is extended, the second frame part 102 is pushed to extend out of the first frame part 100 . When the electric cylinder or the linear motor contracts, the second frame part 102 is pulled to shrink into the first frame part 100 .

As shown in FIG. 4 , according to still other embodiments of the present invention, the driving device 106 is disposed on the first frame part 100 , and the electronic device further includes a transmission assembly. The transmission assembly is connected with the driving device 106 . At the same time, the transmission assembly is also connected to the second frame part 102 . In this embodiment, the driving device 106 does not directly drive the second frame to move, but drives the transmission assembly to drive the second frame part 102 to move.

The driving device 106 drives the transmission assembly to drive the second frame part 102 to move, which is beneficial to more flexibly setting the driving mode and the control mode of the second frame moving distance. The limiting manner of the second frame part 102 can also be more flexible. In addition, since the shape of the second frame tends to be flat, using the driving device 106 to drive the transmission assembly to drive the second frame part 102 to move is also conducive to reducing the number of driving devices 106, reducing the difficulty of control, and improving the performance of the second frame part 102. Synchronization of part movements.

The transmission assembly can be a gear structure, a belt structure, or a sprocket structure, or a combination of a gear structure, a sprocket structure, and a belt structure.

According to some embodiments of the present invention, the transmission assembly includes a connecting rod 108 , a gear assembly 110 and a rack 112 . The link 108 is provided on the first frame part 100 . The connecting rod 108 is connected with the driving device 106, and the driving device 106 is used to drive the connecting rod 108 to rotate.

It should be noted that there are many ways for the driving device 106 to drive the connecting rod 108. For example, the drive shaft of the driving device 106 is provided with gears, and the connecting rod 108 is also provided with gears. gears mesh with each other, so that the driving device 106 can drive the connecting rod 108 to rotate. Or the drive shaft of the driving device 106 is provided with a pulley, and the connecting rod 108 is also provided with a pulley, and the two pulleys are driven by a belt, so that the driving device 106 can drive the connecting rod 108 . Alternatively, a sprocket is sheathed on the driving shaft, and a sprocket is also sheathed on the connecting rod 108 , and a chain is sheathed between the two sprockets, and the driving device 106 drives the connecting rod 108 through the chain and the sprocket. The above method has a large number of embodiments in the related art. Those skilled in the art can flexibly select the driving structure between the driving device 106 and the connecting rod 108 according to the driving requirements, space requirements, etc., therefore, in FIG. 4 In , only the positions of the driving device 106 and the connecting rod 108 are shown, but the specific driving structure between the two is not shown.

As shown in FIG. 3 and FIG. 6 , two ends of the first frame part 100 are respectively provided with a gear box 118 , and as shown in FIG. 7 , the gear assembly 110 is installed in the gear box 118 . Both ends of the connecting rod 108 are respectively connected to a gear assembly 110 , and the connecting rod 108 is used to transmit the torque of the driving device 106 to the gear assembly 110 . A rack 112 is disposed on the second frame portion 102 . The rack gear 112 meshes with the gear assembly 110 . The driving device 106 is a motor.

The torque generated by the motor is transmitted to the connecting rod 108, and the connecting rod 108 then transmits the torque to the gear assembly 110 at both ends thereof, and the gear assembly 110 pushes the second frame to expand and contract by meshing with the rack 112.

The driving device 106, or in other words, the motor is not directly connected with the connecting rod 108, but is transmitted through gears, sprockets, etc., so that the motor can avoid any end of the connecting rod 108, so that the two ends of the connecting rod 108 can be connected separately. A gear assembly 110 is connected. Correspondingly, both ends of the second frame part 102 can obtain driving force, and since the driving force at both ends, or the torque, comes from the connecting rod 108, the two ends of the second frame part 102 can keep synchronously expanding and contracting, thereby ensuring This ensures the stability of the stretching and retracting of the flexible screen 104, and avoids stagnation caused by asynchrony at both ends.

In the above-mentioned embodiment, the second frame part 102 realizes expansion and contraction through the engagement of the gear assembly 110 and the rack 112, which can ensure sufficient thrust to push the second frame part 102 to expand and contract, and the motor only needs to rotate forward or reverse, The extension or retraction of the second frame part 102 can be realized, and the expansion and contraction of the flexible screen 104 can be realized accordingly. In addition, the gear assembly 110 meshing with the rack 112 is also beneficial to control the moving distance of the second frame part 102 by controlling the number of revolutions of the motor. In addition, the gear assembly 110 meshes with the rack 112. When the second frame part 102 stops at any position, the meshing of the gear and the rack 112 can also play a position-limiting role, so that the flexible screen 104 is fixed at the position when it stops moving. In terms of width, in other words, the width of the flexible screen 104 can be adjusted as required, thereby further improving the convenience of using the electronic device.

As shown in Figure 9 and Figure 10, correspondingly, the two ends of the second frame part 102, that is, the top end and the bottom end are respectively provided with racks 112, so as to mesh with the gear assembly 110, so that both ends of the second frame part 102 are It can be pushed by the gear assembly 110 and the rack 112 to improve the stability of the telescopic movement of the second frame part 102 .

As shown in FIG. 11 , FIG. 12 and FIG. 16 , further, the rack 112 is provided with a groove-shaped guide portion 1120 . The first part of the flexible screen 104 is fixed on the first frame part 100 , and the second part of the flexible screen 104 is slidably disposed in the groove-shaped guide part 1120 . The second frame part 102 protrudes outward from the first frame part 100 , and the second part of the flexible screen 104 slides from the back side along the guide part 1120 to the front side to stretch. The second frame part 102 retracts into the first frame part 100 , and the second part of the flexible screen 104 slides from the front side along the guide part 1120 to the back side to be folded.

In the above-mentioned embodiment, through the setting of the guide part 1120, another part of the flexible screen 104 can be relatively fixed in the guide part 1120 and not easy to fall out of the second frame part 102, thereby ensuring that the flexible screen 104 can be stretched and folded smoothly. Specifically, when the second frame part 102 protrudes outward from the first frame part 100 , the second part of the flexible screen 104 slides from the back side along the guide part 1120 to the front side, so that the flexible screen 104 is stretched. When the second frame part 102 is retracted into the first frame part 100 , the second part of the flexible screen 104 slides from the front side along the guide part 1120 to the back side, so that the flexible screen 104 is folded. During the above process, part of the flexible screen 104 always remains in a bent state.

According to some other embodiments of the present invention, racks 112 are respectively provided on the front side and the back side of the second frame part 102 . There are racks 112 on the front side and the back side respectively, that is, both sides of the gear assembly 110 have racks 112 meshing, so that the force on the gear assembly 110 is more uniform, and accordingly, it is beneficial to maintain the torque transmission. Stability and reliability, so as to further improve the stability of the movement of the second frame part 102 and ensure that the flexible screen 104 can be stretched and folded smoothly.

As shown in FIG. 8 , according to some embodiments of the present invention, the gear assembly 110 includes a first gear 1100 , a second gear 1102 , a third gear 1104 and a fourth gear 1106 . The first gear 1100 is connected with the connecting rod 108 . The second gear 1102 meshes with the first gear 1100, and the second gear 1102 also meshes with the rack 112 on the front side. The third gear 1104 meshes with the first gear 1100 . The fourth gear 1106 meshes with the third gear 1104, and the fourth gear 1106 also meshes with the rack 112 on the rear side.

The four gears are meshed, so that the gears on both sides can generate torque in opposite directions, and correspondingly, the racks 112 on the front side and the back side can be pushed to move in the same direction.

As shown in FIG. 8 , specifically, when the first gear 1100 rotates counterclockwise, the second gear 1102 and the third gear 1104 rotate clockwise, and the second gear 1102 pushes the rack 112 on the first side to move rightward. At the same time, the fourth gear 1106 rotates counterclockwise, pushing the rack 112 on the second side to move to the right, so that the second frame part 102 moves to the right as a whole, that is, the second frame part 102 moves outward from the first frame part 100 as a whole, The flexible screen 104 is stretched.

As shown in FIG. 8 , when the first gear 1100 rotates clockwise, the second gear 1102 and the third gear 1104 rotate counterclockwise, and the second gear 1102 pushes the rack 112 on the front side to move to the left. At the same time, the fourth gear 1106 rotates clockwise, pushing the rack 112 on the second side to move to the left, so that the second frame part 102 moves to the left as a whole, that is, the second frame part 102 moves in the first frame part 100 as a whole, The flexible screen 104 is folded. It can be understood that the first frame part 100 has a fixed side and a drawer side that are oppositely disposed. The second frame part 102 performs telescopic movement from the drawing side. The distance from the gear assembly 110 to the drawing side is smaller than the distance from the gear assembly 110 to the fixed side.

The distance from the gear assembly 110 to the drawing side is smaller than the distance from the gear assembly 110 to the fixed side, that is to say, the gear assembly 110 is disposed on the first frame part 100 close to the drawing side. This facilitates the maximum movement of the second frame part 102 . Specifically, the rack 112 extends from the fixed side to the drawer side. Since the gear assembly 110 is arranged near the drawer side, as the second frame part 102 moves outward, the rack 112 also extends from the fixed side to the drawer side. Move in the direction of the pull side. At the beginning of the outward movement of the second frame part 102, the gear assembly 110 contacts and meshes with the part of the rack 112 near the drawing side; Partial contact and engagement, at this moment, the outward movement distance of the second frame part 102 is close to the entire width of the second frame part 102 . Therefore, the gear assembly 110 is disposed near the drawer side, which is beneficial to increase the moving distance of the second frame part 102 , and correspondingly, can increase the stretched width of the flexible screen 104 .

According to other embodiments of the present invention, the electronic device further includes an elastic member 114 . One end of the elastic member 114 is connected to the first frame portion 100 , and the other end of the elastic member 114 is connected to the flexible screen 104 .
