The stopper may be an additional component independent from the housing 100, and may also be a part of the housing 100.

For example, the stopper may be a shaft such as the shaft 200, and the shaft 200 may be detachably coupled to the housing 100 so that the shaft 200 may move relative to the housing 100, for example, the shaft 200 may be disposed between a first side and a third side, one end of the shaft 200 may be detachably coupled to the other end of the first side, and the other end of the shaft 200 may be detachably coupled to the other end of the third side so that the shaft 200 may reciprocate in a direction parallel to the housing 100.

It should be noted that the shaft 200 may also have an irregular structure, for example, a part of the surface of the shaft 200 has an arc structure, and a part of the surface has a square structure.

Referring to fig. 3, fig. 3 is a schematic view of a second structure of an electronic device according to an embodiment of the present application. The electronic device 20 may further include a flexible screen assembly such as the flexible screen assembly 300, and the flexible screen assembly 300 may include a narrow screen mode as shown in fig. 1 in which a display area of the flexible screen assembly 300 is fixed and a wide screen mode as shown in fig. 3; in the wide screen mode, the display area of the flexible screen assembly 300 may be expanded. For example, the flexible screen assembly 300 may include a flexible display module 310 and a deformable support member, which is located on a non-display surface side of the flexible display module 310 and is used for supporting the flexible display module 310. It can be understood that, the structural strength of the support member is higher, and on the one hand, the flexible display module 310 can be supported, and the flatness of the flexible display module is improved, so that the flexible display module 310 is not easy to collapse or wrinkle in the display process, and on the other hand, the support member can also improve the overall strength of the flexible screen assembly 300, and the flexible screen assembly 300 can be protected from being damaged in the stretching process. The flexible display module 310 may be an OLED (Organic Light Emitting Diode) module, which includes a display substrate and an encapsulation material, wherein an Organic Light Emitting object is encapsulated between the display substrate and the encapsulation material, the OLED module includes a plurality of OLED units, and each OLED unit is electrically connected to a main board of an electronic device to achieve self-Light emission and display images. The flexible Display module 310 may also be an LCD (Liquid Crystal Display) module, which may include a Display substrate and an encapsulation material, a Liquid Crystal material is encapsulated between the Display substrate and the encapsulation material, a main board of the electronic device provides a voltage for the Liquid Crystal material, so as to change an arrangement direction of Liquid Crystal molecules, and light projected by the backlight forms an image in a Display area after passing through an internal common effect of the LCD module, so as to Display a picture.

The flexible display module 310 may include a main body portion 311 and an extension portion 312, the main body portion 311 is disposed on the housing 100, and the extension portion 312 is movable relative to the housing 100, so that the extension portion 312 may be deployed outside the housing 100 or retracted inside the housing 100. During the movement of the extension portion 312, the extension portion can be deformed to be converted between a bent state and a flat state, and the position-limiting element is located at the bent position of the extension portion 312 and abuts against the supporting element, so that the position-limiting element and the supporting element can support the bent position of the extension portion 312 together.

With reference to fig. 2, the supporting member may further include a soft adhesive connecting band such as the soft adhesive connecting band 320320, and the hardness (shore a) of the soft adhesive connecting band 320 is 60-75 degrees, such as 65 degrees, 68 degrees, 70 degrees or 75 degrees. The soft adhesive connecting tape 320 may be made of rubber, silicone, TPU (Thermoplastic polyurethane elastomer rubber), or the like. The soft adhesive tape 320 is disposed on the non-display surface of the extension portion 312, and the soft adhesive tape 320 can provide a flat bearing surface for the extension portion 312, so that the extension portion 312 can be unfolded smoothly without wrinkles or depressions. Compared with a rigid material, the hardness of the soft rubber connecting band 320 adopted in the embodiment of the application is between 60 degrees and 75 degrees, so that the damage to the extension part 312 in the movement process of the soft rubber connecting band 320 can be reduced, and the contact surface between the extension part 312 and the soft rubber connecting band 320 is protected from being easily abraded. In addition, the expanded portion 312 is easily broken because the expanded portion 312 may frequently rub against the shaft 200 during movement. In the embodiment of the application, the soft rubber connecting band 320 is additionally arranged on the extension part 312 which needs to move, so that the friction force which originally acts on the extension part 312 can be transferred to the soft rubber connecting band 320, and the extension part 312 can be further protected.

The soft rubber connection band 320 is provided with a second limit structure such as a second limit structure, the second limit structure is arranged on one side of the soft rubber connection band 320 far away from the extension part 312, and the second limit structure can be matched with the first limit structure. Such as: when first limit structure is the protrusion structure, the second limit structure can be groove structure, and first limit structure can be held in second limit structure this moment to be connected with second limit structure interference fit, make flexible glue connecting band 320 move according to the motion trail of predetermineeing (for example do linear motion along the direction that is on a parallel with casing 100) under first limit structure and second limit structure's limiting displacement, and then make extension 312 move to casing 100 outside or inside casing 100 according to predetermineeing the motion trail. For another example: when the first limiting structure is a groove structure, the second limiting structure can be a convex structure, and the second limiting structure can be accommodated in the first limiting structure and is connected with the groove wall of the first limiting structure in an interference fit manner. Also for example: when the number of the first limiting structures is multiple, a part of the first limiting structures are protruding structures, and a part of the first limiting structures are groove structures, a plurality of second limiting structures can be correspondingly arranged on the outer surface of the soft rubber connecting band 320, wherein a part of the second limiting structures are matched with the protruding structures, and a part of the second limiting structures are matched with the groove structures. It can be understood that the first limit structure and the second limit structure are matched in shape and size and abut against each other, so as to limit the movement path of the soft rubber connecting band 320.

When the flexible screen assembly 300 is in the narrow screen mode or the wide screen mode, the main body portion 311 is always fixed on the outer surface of the housing 100 to be exposed outside the electronic device 20, at this time, the extension portion 312 is in a storage state, at this time, the extension portion 312 is hidden inside the housing 100 and cannot be used for displaying information, and only the main body portion 311 of the flexible screen assembly 300 is used for displaying information; when the flexible screen is switched from the narrow-screen mode to the wide-screen mode, a user may pull the shaft 200 to move in a direction away from the housing 100 (or may set the driving mechanism to drive the shaft 200 to move), the shaft 200 may drive at least a portion of the extension portion 312 to gradually rotate out of the housing 100 along the outer surface of the shaft 200 in the moving process, and at least a portion of the extension portion 312 is exposed outside the housing 100 at this time, so that the narrow-screen mode is switched to the wide-screen mode. The extension portion 312 exposed to the outside may display information together with the main body portion 311, and a display area may be increased relative to the information display using only the main body portion 311. When the flexible screen is switched from the wide-screen mode to the narrow-screen mode, the extension portion 312 may be gradually rotated into the interior of the housing 100 along the outer surface of the shaft 200 in a direction close to the housing 100 (the extension or the storage of the flexible screen assembly 300 may be achieved by a manual driving manner or a mechanical driving manner), so that at least a portion of the extension portion 312 is stored in only the housing 100, and the extension portion 312 drives the shaft 200 to move in the direction of the housing 100 during the movement process, thereby shortening the distance between the shaft 200 and the housing 100 (or may also drive the reciprocating movement of the shaft 200 in the mechanical driving manner).

According to the embodiment of the application, the soft glue connecting band is arranged on the extension part, so that the damage degree of the flexible screen assembly 300 in the moving process can be reduced, and the service life of the flexible screen assembly 300 is prolonged. In addition, this application embodiment still through mutually supporting of first limit structure and second limit structure for flexible screen subassembly 300 expandes outside casing 100 or accomodates in casing 100 according to preset movement track, compares in relevant art, and this application embodiment can make the extension in-process of flexible screen subassembly 300 not take place the skew, and then makes flexible screen subassembly 300 not take place to pull at the length direction of electronic equipment 20, further protects flexible screen subassembly 300 not damaged.

Fig. 4 is a schematic view of a first side view of the shaft and flexible screen assembly of fig. 2, as shown in fig. 4. The size of the soft glue connection band 320 is equal to the size of the extension part 312, and the projection of the soft glue connection band 320 on the flexible screen assembly 300 is located on the extension part 312, so that the soft glue connection band 320 can cover the non-display surface of the whole extension part 312, and further protect the whole extension part 312. Compared with the related art, the flexible screen is directly used as a stretching main body, the soft rubber connecting band 320 is arranged on the extension part 312, the extension part 312 can be in direct contact with the shaft 200 at intervals, and therefore abrasion to the extension part 312 in the process that the non-display surface of the extension part 312 is directly rubbed with the outer surface of the shaft 200 is avoided.

Fig. 5 is a schematic view of a second side view of the shaft and flexible screen assembly of fig. 2, as shown in fig. 5. The size of the soft glue link 320 may also be larger than the size of the extension 312. When the size of the soft adhesive connecting band 320 is larger than that of the extension part 312, a part of the projection of the soft adhesive connecting band 320 on the flexible screen assembly 300 is located at the extension part 312, and a part of the projection is located outside the extension part 312, for example, the projection can be located on the main body part 311, or can be located in the accommodating space of the housing 100, for example, the projection can be used for connecting a driving motor, and the driving motor drives the extension part 312 to unfold or recycle by driving the part of the soft adhesive connecting band 320 located in the accommodating space of the housing 100 to curl or unfold.

When a portion of the soft gum connection band 320 is located at the main body part 311, the outer surface of the side of the soft gum connection band 320 is flush with the outer surface of the side of the main body part 311. For example, the soft rubber connecting band 320 and the main body part 311 are both cuboid structures, the soft rubber connecting band 320 can have four interconnected lateral parts, the soft rubber connecting band 320 has two opposite surfaces, and the two surfaces are connected to the two sides of the four lateral parts to form the cuboid structures in a surrounding manner. Similarly, the main body 311 may also have four mutually connected side portions, and a display surface and a non-display surface opposite to each other, wherein the soft adhesive connection band 320 is disposed on the non-display surface of the main body 311, four outer surfaces of the side portions of the soft adhesive connection band 320 are flush with the outer surfaces of the four side portions of the main body 311, the soft adhesive connection band 320 may support the main body 311, so that the display surface of the main body 311 is smoother, the soft adhesive connection band 320 cannot be observed from the outside, and the appearance of the flexible screen assembly 300 is kept simple.

As shown in FIG. 6, FIG. 6 is a schematic cross-sectional view of the shaft and flexible screen assembly of FIG. 2 taken along the line P1-P1. The first position-limiting structure includes a first position-limiting groove 210, the first position-limiting groove 210 is disposed around the outer surface of the shaft 200, and the groove width of the first position-limiting groove 210 gradually narrows from the outer surface of the shaft 200 toward the inner surface of the shaft 200. The second limiting structure comprises a first limiting protrusion 321, the first limiting protrusion 321 is arranged on the outer surface of the soft rubber connecting band 320 and protrudes out of the surface of the soft rubber connecting band 320, the outer surface of the soft rubber connecting band 320 refers to the surface far away from the flexible screen assembly 300, and the inner surface of the soft rubber connecting band 320 refers to the surface connected with the non-display surface of the flexible screen assembly 300. Wherein, the material of first spacing arch 321 is the same with the material of soft glue connecting band 320, for example, all rubber, and the width of first spacing arch 321 widens gradually from the internal surface of soft glue connecting band 320 towards the outer surface direction of soft glue connecting band 320, make the shape of first spacing arch 321 can match with the shape of first spacing groove 210, first spacing arch 321 can be embedded into first spacing groove 210, and first spacing arch 321 can restrict the movement track of flexible screen subassembly 300 through first spacing groove 210, make extension 312 move to casing 100 in or outside casing 100 according to the orbit of predetermineeing. First spacing arch 321 is connected with first spacing groove 210 interference fit, for example, the size of first spacing arch 321 slightly is greater than the size of first spacing groove 210, when first spacing arch 321 is installed to first spacing groove 210, the surface of first spacing arch 321 extrudes with the cell wall of first spacing groove 210 each other, in order to increase the butt fastness of first spacing groove 210 and first spacing arch 321, can also increase the coefficient of friction between axle 200 and the flexible glue connecting band 320, form effective friction district between axle 200 and flexible glue connecting band 320. It can be understood that if the friction coefficient between the shaft 200 and the soft adhesive connecting band 320 is too small, the soft adhesive connecting band 320 may slip during the movement of the shaft 200, and the expansion and storage of the expansion portion 312 may be unsmooth. According to the embodiment of the application, the soft rubber connecting band 320 can not slide easily through the first limit groove 210 and the first limit protrusion 321, and the display reliability of the flexible screen assembly 300 is further ensured. It should be noted that the shape of the first limiting groove 210 is not limited to this, for example, the first limiting groove 210 may also be a dovetail groove, a square groove, or the like.

Fig. 7 to 10 show a first structural schematic diagram of a flexible screen assembly according to an embodiment of the present application, fig. 7 shows a first structural schematic diagram of a first supporting sheet in the flexible screen assembly shown in fig. 7, fig. 9 shows a partial structural schematic diagram of the first supporting sheet shown in fig. 8, fig. 10 shows a sectional structural schematic diagram of the first supporting sheet shown in fig. 8 along P3-P3, and fig. 11 shows a sectional structural schematic diagram of the first supporting sheet shown in fig. 8 along P4-P4.

The supporting member may further include a first supporting sheet 330, the first supporting sheet 330 is a rigid structure, for example, the first supporting sheet 330 may be made of a metal material, and the first supporting sheet 330 may be a steel sheet, an aluminum sheet, a copper sheet, or the like. The first supporting plate 330 may also be made of rubber or silicone. The first supporting sheet 330 is embedded in the soft rubber connecting band 320, for example, the injection molding of the first supporting sheet 330 can be used to form the soft rubber connecting band 320, so that the first supporting sheet 330 is wrapped in the soft rubber connecting band 320, and the first supporting sheet 330 is not in direct contact with the flexible screen assembly 300, thereby protecting the flexible screen assembly 300.

The first supporting sheet 330 may be deformed to switch the first supporting sheet 330 between a first state in which the first supporting sheet 330 is straight to support the extension 312 in the straight state and a second state; in the second state, the first supporting piece 330 is bent to support the expanded portion 312 in the bent state. It is understood that the first supporting sheet 330 is a deformable structure, which can be switched between a first state and a second state according to the state of the extension portion 312, so that the first supporting sheet 330 can support both the extension portion 312 in the bent state and the extension portion 312 in the flat state.

For example, the first support sheet 330 may include a first side portion 331, a second side portion 332, and a recess 333, the recess 333 being located between the first side portion 331 and the second side portion 332, the first side portion 331 being located at one end portion of the shaft 200, the second side portion 332 being located at the other end portion of the shaft 200, the recess 333 being located at a middle position of the shaft 200. Wherein the recess 333 is formed by bending towards a direction away from the flexible display module 310. It is understood that the structure of the first support sheet 330 is similar to that of a tape measure, the cross section of the first support sheet 330 in the width direction of the electronic device 20 has an arc-shaped structure, and the bending direction of the first support sheet 330 faces away from the shaft 200. When the soft adhesive tape 320 moves along the outer surface of the shaft 200, the first supporting sheet 330 may be deformed to switch the recess 333 between the first bending state and the second bending state.

For example, when the first supporting sheet 330 is in the first state, the recess 333 is in a first bending state, which is a state of bending in a direction away from the flexible display module 310. When the soft rubber connecting band 320 moves along the shaft 200, the soft rubber connecting band 320 moving to the position of the shaft 200 can abut against the shaft 200, and in the process, the first supporting sheet 330 positioned inside the soft rubber connecting band 320 can receive the radial acting force along the shaft 200 through the soft rubber connecting band 320 and deform, so that the concave part 333 is switched to a second bending state from the first bending state, and the rest of the first supporting sheet which is not abutted against the shaft 200 is kept in the original state, namely, is in the first bending state. The second bending state refers to a state in which the recessed portion 333 is bent toward a direction close to the flexible display module 310, so that the bending direction of the first support sheet 330 is the same as the radian of the shaft 200, the fitting degree of the soft rubber connecting band 320 and the shaft 200 is further improved, and the movement of the soft rubber connecting band 320 is more stable. When the soft adhesive connecting band 320 gradually moves to the outside of the casing 100 or the inside of the casing 100 along the outer surface direction of the shaft 200, the soft adhesive connecting band originally abutted to the shaft 200 gradually moves away from the shaft 200, and the extrusion acting force of the shaft 200 on the first supporting sheet 330 is gradually cancelled, so that the recess 333 is switched from the second bending state to the first bending state.

It can be understood that, in the first state of the first supporting sheet 330, the cross-sectional shape of the first supporting sheet 330 is as shown in fig. 10, and the first supporting sheet 330 is concave in the first state, and only needs to push against the back surface of the first supporting sheet 330 with a little force, so that the first supporting sheet 330 can be deformed and turned into a straight shape, such that the shape of the first supporting sheet 330 is the same as that of the extension portion 312, and the extension portion 312 can move along the surface of the shaft 200. Based on the structure of the first supporting sheet 330, the first supporting sheet 330 can be deformed when receiving an acting force along the radial direction of the shaft 200, and can be turned from a concave shape to a straight shape, as shown in fig. 11; and returns to the original concave shape after receiving no force in the radial direction of the shaft 200.

It should be noted that the structure of the first supporting sheet 330 is not limited to this, for example, the first supporting sheet 330 may have a plurality of concave portions 333, the plurality of concave portions 333 are arranged at intervals, one concave portion 333 is formed by bending in a direction away from the flexible display module 310, when the extension portion moves onto the shaft 200, all or part of the concave portions 333 deform when receiving a force along the radial direction of the shaft 200, so that the concave portions 333 bend from the non-display surface of the main body portion to the display surface of the main body portion, and at this time, the plurality of concave portions 333 are switched from the first bending state to the second bending state. When the extension portion 312 is away from the shaft 200, the recess 333 is restored to a state of being bent in a direction away from the flexible display module 310.

It can be understood that, if the first supporting sheet 330 is a common flat rigid structure, when the first supporting sheet 330 moves to the position of the shaft 200, due to the interaction force between the shaft 200 and the first supporting sheet 330, the first supporting sheet 330 is deformed into a bent state and the first supporting sheet 330 is attached to the outer surface of the shaft 200, when the first supporting sheet 330 leaves the position of the shaft 200, the interaction force between the shaft 200 and the first supporting sheet 330 disappears, but because the first supporting sheet 330 is a flat rigid structure, after being deformed, without other action force, the first supporting sheet cannot recover the original flat state, for example, the original bent state is presented, so that the expansion portion 312 is also made to present an uneven condition, and the display effect of the electronic device 20 is affected. The recess 333 of the present application can be switched between the first bending state and the second bending state, such that when the shaft 200 is in the position (or in the bent position), the first bending state is switched to the second bending state, and when the shaft is moved to another position, the second bending state is switched back to the first bending state, such that the expansion portion 312 can be freely switched between the expanded state and the retracted state, and the expansion portion 312 can be kept flat both in the expanded state and the retracted state, thereby reducing the influence of the movement process of the expansion portion 312 on the display effect of the electronic device 20.

In other embodiments, the soft adhesive tape 320 may not be provided, and instead, the first support sheet 330 may be directly provided on the non-display surface of the extension 312. The first support sheet 330 may be directly adhered to the non-display surface of the extension 312 using an adhesive such as a double-sided tape or glue.

For example, the first supporting sheet 330 may be directly disposed on the non-display surface side of the flexible display module 310, and the first supporting sheet 330 may be deformed to convert the first supporting sheet 330 between a first state and a second state, where in the first state, the first supporting sheet 330 is straight to support the extension portion 312 in the straight state; in the second state, the first supporting piece 330 is bent to support the expanded portion 312 in the bent state. It is understood that the first supporting sheet 330 is a deformable elastic structure, which can be switched between a first state and a second state according to the state of the extension portion 312, so that the first supporting sheet 330 can support both the extension portion 312 in the bent state and the extension portion 312 in the flat state.

When the first support sheet 330 is in the first state, a part of the first support sheet 330 is not in contact with the expanded portion 312, for example, the middle of the first support sheet 330 has a concave structure, two sides of the first support sheet 330 are in contact with the expanded portion 312, and the middle of the first support sheet 330 has a gap with the expanded portion 312; it is also possible that the first support sheet 330 has a plurality of concave structures, the first support sheet 330 has a gap with the extension portion 312 at a portion having the concave structures, and other portions of the first support sheet 330 are in contact with the extension portion 312 or in contact with the non-display surface of the extension portion 312. When the first supporting sheet 330 is in the second state, the first supporting sheet 330 deforms due to the radial acting force along the shaft 200 received by the first supporting sheet 330, so that a part of the first supporting sheet 330, which is not in contact with the extension part 312, is attached to the display surface of the extension part 312, and the appearance of the first supporting sheet 330 is consistent with that of the extension part 312, thereby ensuring that the flexible screen assembly 300 can be repeatedly unfolded and recovered according to a preset movement track.

When the expanded portion 312 is positioned within the housing 100, a portion of the first support tab 330 abuts the shaft 200. For example, a portion of the first support sheet 330 abuts a surface of the shaft 200 and a portion of the first support sheet 330 does not contact the shaft 200 (it is understood that a portion of the first support sheet 330 is not adjacent the shaft 200).

When the expanded portion 312 is positioned outside the housing 100, a portion of the first support piece 330 abuts the shaft 200. For example, a portion of the first support sheet 330 abuts a surface of the shaft 200 and a portion of the first support sheet 330 does not contact the shaft 200 (it is understood that a portion of the first support sheet 330 is not adjacent the shaft 200). It will be appreciated that a portion of the extension 312 now lies flat outside the housing 100 and a portion of the extension 312 fits over the surface of the shaft 200.

The size of the first support sheet 330 in the moving direction of the extension portion 312 may be greater than or equal to the size of the extension portion 312, and when the size of the first support sheet 330 in the moving direction of the extension portion 312 is equal to the size of the extension portion 312, the projection of the first support sheet 330 on the flexible screen assembly 300 is located at the extension portion 312, so that the first support sheet 330 may cover the entire non-display surface of the extension portion 312, thereby supporting the entire extension portion 312. For among the correlation technique, directly regard as tensile main part with flexible display module, this application sets up first supporting piece 330 at extension 312, can interval extension 312 and axle 200 direct contact, and then avoid extension 312's the direct external surface friction process of non-display face and axle 200 to the wearing and tearing that extension 312 caused. When the size of the first supporting sheet 330 is larger than the size of the expanding portion 312, a part of the projection of the first supporting sheet 330 on the flexible screen assembly 300 is located on the expanding portion 312, and a part of the projection is located outside the expanding portion 312, for example, the first supporting sheet may be located on the main body portion 311, or may be located in the accommodating space of the housing 100.

When a portion of the first support sheet 330 is located at the body portion, the side outer surface of the first support sheet 330 is flush with the side outer surface of the body portion 311. For example, the first supporting sheet 330 and the main body portion 311 are both of a rectangular parallelepiped structure, the first supporting sheet 330 may have four sides connected to each other, and the first supporting sheet 330 has two opposite surfaces connected to both sides of the four sides to form the rectangular parallelepiped structure. Similarly, the main body 311 may also have four sides connected to each other and an opposite display surface and a non-display surface, wherein the first supporting sheet 330 is disposed on the non-display surface of the main body 311, four outer side surfaces of the first supporting sheet 330 are flush with four outer side surfaces of the main body 311, and the first supporting sheet 330 may support the main body 311, so that the display surface of the main body 311 is more flat, and the first supporting sheet 330 is not visible from the outside, thereby maintaining the appearance simplicity of the flexible screen assembly 300.

It should be noted that the first supporting sheet 330 may not be located on the main body portion 311, for example, as shown in fig. 12, fig. 12 is a schematic view of a first partial structure of the first supporting sheet and the second supporting sheet provided in the embodiment of the present application, and the supporting member may further include a second supporting sheet 340, where the second supporting sheet 340 is located on the non-display surface of the main body portion 311. The structure of the second supporting sheet 340 is different from that of the first supporting sheet 330, for example, the second supporting sheet 340 is a straight structure and does not have an arc-shaped structure, and the second supporting sheet 340 can provide a flat supporting surface for the body portion 311. It should be noted that the second supporting sheet 340 may have the same structure as the first supporting sheet 330, which may facilitate the processing.

It can be understood that, in order to realize that the display screen module is in the stretching and bending area, the display screen module can be continuously and continuously bent from the flat state to the bent state according to the bending shape, and then from the bent state to the flat state, obviously, the material capable of realizing the transition of the two states is generally a flexible material, and the material is required to be in the stretching state, such as each layer of film material in the display screen module, but if only the flexible material exists, in the stretching and shrinking bending part, one end of the flexible material can not be drawn according to the set bending track in the stretching state. And the display screen module can not be stressed directly under the stretching state, because the display screen module is easy to damage. Obviously, to realize that the display screen module realizes flexible according to set orbit in the position of bending to guarantee that the display screen body does not receive the force alone, consequently need increase in the district of bending and adhere to rigid structure, but if adopt general rigid structure can't realize flattening and buckle repeated switching. In the embodiment of the present application, the structure of the first supporting sheet 330 is improved, so that the first supporting sheet 330 can be switched between the first bending state and the second bending state, and further the flexible screen can be easily switched between the unfolding state and the folding state.

It should be noted that the structure of the first supporting sheet 330 is not limited to this, for example, the first supporting sheet 330 may deform in the width direction of the electronic device 20, so that the first supporting sheet 330 may be stretched in the process of moving the outer surface of the shaft 200, thereby ensuring that the first supporting sheet 330 can easily support the extension portion 312 in the telescopic bending area and can be telescopically bent in the process of moving along the outer surface of the shaft 200 without damage risk. It will be appreciated that if the rigid plate is provided directly on the non-display surface of the extension 312, the rigid plate may be damaged by breaking due to insufficient tension when moving to the position of the shaft 200. If the rubber member or the spring-type elastic member is directly used, the supporting force for the extension portion 312 may be insufficient due to the excessive elasticity, and the flexible screen assembly 300 may be wrinkled or dented.

For example, as shown in fig. 13, fig. 13 is a schematic view of a second partial structure of the first support sheet and the second support sheet according to the embodiment of the present application. All or a part of the first support sheet 330 is provided with a plurality of mesh openings such as the mesh openings 334 to improve the deformability of the first support sheet 330, for example, the first support sheet 330 may be etched with an acidic etching solution to etch a plurality of diamond-shaped mesh openings 334 on the first support sheet 330, so that the first support sheet 330 has a diamond-shaped screen structure, and the diamond-shaped screen structure may provide the first support sheet 330 with stretchability in the width direction and/or the length direction of the electronic device 20. When the first supporting sheet 330 moves in the width direction of the electronic device 20, the first supporting sheet 330 may receive the pressing force applied by the shaft 200 and the pulling force along the width direction of the electronic device 20, and may deform under the pressing force and the pulling force, and compared with a rigid sheet, the first supporting sheet 330 according to the embodiment of the present application may ensure that the first supporting sheet 330 may not break due to an excessive tension in the moving process.

The mesh openings 334 may be regular in shape, such as diamond shaped structures, rectangular shaped structures, etc., or the mesh openings 334 may be irregular in shape. For example, the mesh openings 334 of the embodiment of the present application are in a diamond-shaped structure, and the first support sheet enables all or a portion of the first support sheet 330 to form a diamond-shaped mesh structure, and the first support sheet 330 having the diamond-shaped mesh structure has the advantages of excellent flexibility, great advantage in ensuring flatness of the flexible screen assembly 300, and long bending life.

Wherein, when the size of the first support sheets 330 is equal to that of the expanded portion 312, the first support sheets 330 may be all processed into a diamond-shaped wire mesh structure; when the size of the first support sheet 330 is larger than that of the extension portion 312, the portion of the first support sheet 330 on the non-display surface of the extension portion 312 may be processed into a diamond-shaped wire mesh structure, and the other portion of the first support sheet 330 is a flat rigid sheet structure, which does not need to be etched by using an etching solution, for example, the portion of the first support sheet 330 on the non-display surface of the main body portion 311. It is understood that the first support sheet 330 may include a first section disposed on the non-display surface of the main body portion 311 in a completed rigid sheet structure with a mesh-free surface design and a second section disposed on the non-display surface of the extension portion 312 in a diamond-shaped structure with a plurality of mesh holes 320, such that the second section forms a diamond-shaped wire mesh structure. Because the first supporting sheet 330 is mainly stressed on the non-display surface of the expansion part 312 during the movement of the first supporting sheet 330, only a part of the first supporting sheet 330 is processed into a diamond-shaped wire mesh structure, on one hand, the deformability of the first supporting sheet 330 is ensured, on the other hand, the supporting strength of the whole first supporting sheet 330 can be ensured, and the difficulty and cost of manufacturing can be reduced.

Fig. 14 is a schematic view of a second structure of the flexible screen assembly according to the embodiment of the present application, which is shown in fig. 8 and 14. The electronic device 20 further includes a protective layer 400, and the protective layer 400 may be a PI (polyimide film) film. Of course, the protection layer 400 may also be a film structure made of other materials, such as a PET (Polyethylene terephthalate) film, a PE (Polyethylene) film, and the like. The first support sheet 330 is interposed between the two protective layers 400, and the protective layers 400 cover the mesh openings 334 to close the mesh openings 334, so that an object (such as an adhesive, e.g., a double-sided tape, glue, etc.) disposed on the first support sheet 330 does not penetrate into other components through the mesh openings 334. For example, the first support sheet 330 may include a first side and a second side that are oppositely disposed, the first side being a side near the non-display side of the flexible screen assembly 300, and the second side being a side away from the flexible screen assembly 300. Wherein the first side is provided with a first protection layer 410, the first protection layer 410 is covered on the mesh openings 334 to close the mesh openings 334 from the first side to the second side; the second side is provided with a second protection layer 420, and the second protection layer 420 covers the mesh openings 334 to close the mesh openings 334 from the second side toward the first side, so that an object (such as a double-sided tape, an adhesive such as glue) disposed on the first support sheet 330 (including the first side and the second side) does not penetrate into the flexible screen assembly 300, or the middle frame, or the sliding member through the mesh openings 334.

This application embodiment can not only increase tensile strength through setting up tensile first supporting sheet 330, but also can reduce flexible screen assembly 300's destruction risk, extension flexible screen assembly 300's life.

Fig. 15 is a schematic structural diagram of a first sliding member and a second sliding member provided in an embodiment of the present application, which is shown in fig. 4 and 15. The electronic device 20 may further include a first slider 510 and a second slider 520, for example, the first slider 510 may be disposed on the soft adhesive connecting band 320 and located on the main body portion 311, and the second slider 520 may be disposed on the soft adhesive connecting band 320 and located on the expansion portion 312. The first slider 510 and the second slider 520 are both slidably connected to the soft rubber connecting band 320, and the first slider 510 and the second slider 520 are both disposed at an interval from the shaft 200, and both the first slider 510 and the second slider 520 can slide relative to the soft rubber connecting band 320 along the surface of the soft rubber connecting band 320, so that the extension portion 312 can be unfolded outside the casing 100 or accommodated inside the casing 100 according to the preset movement track.

In the initial state, the first slider 510 is located at the first position (as shown in fig. 4), and the second slider 520 is located at the second position (as shown in fig. 4) of the soft adhesive connecting band 320. When the extension portion 312 moves in the direction out of the housing 100, the first slider 510 and the second slider 520 both move in the direction close to the shaft 200, so that the first slider 510 is located at the third position (as shown in fig. 13), and the second slider 520 is located at the fourth position (as shown in fig. 13), so that the extension portion 312 located outside the housing 100 can be slidably spread along the surface of the first slider 510, and the extension portion 312 located inside the housing 100 can be slid along the surface of the second slider 520 to the surface of the shaft 200. When the expansion portion 312 moves in the direction inside the housing 100, both the first slider 510 and the second slider 520 move in the direction away from the shaft 200, so that the expansion portion 312 located outside the housing 100 can slide along the surface of the first slider 510 to the surface of the shaft 200, and the expansion portion 312 located inside the housing 100 can slide along the second slider 520 to inside the housing 100.

It is understood that the first slider 510 can limit the movement of the extension portion 312 gradually winding around the outer surface of the shaft 200 (or around the outer surface of the shaft 200), and the second slider 520 can limit the movement of the extension portion 312 gradually winding around the outer surface of the shaft 200 (or around the outer surface of the shaft 200), so as to limit the movement track of the whole extension portion 312, such that the extension portion 312 is gradually unfolded out of the casing 100 according to the first preset movement track (or gradually retracted into the casing 100 according to the second preset movement track).

As shown in fig. 16, fig. 16 is a schematic cross-sectional view of the shaft and flexible screen assembly shown in fig. 2 along the direction P2-P2, each of the first slider 510 and the second slider 520 is provided with a sliding portion such as a sliding portion 530, and the size and shape of the sliding portion 530 are matched with the size and shape of the second limit structure on the soft adhesive connecting band 320. For example, when the second position-limiting structure is a groove structure, the sliding part 530 may be a protrusion structure; when the second position-limiting structure is a protrusion structure, the sliding part 530 may be a groove structure.

The soft adhesive connecting band 320 is provided with a limiting portion for limiting the sliding distance between the first slider 510 and the second slider 520. For example, the soft adhesive connecting band 320 is provided with a first limiting portion and a second limiting portion, the first limiting portion is located between the first sliding member 510 and the shaft 200, and the first limiting portion is used for limiting the sliding distance of the first sliding member 510 so as to prevent the first sliding member 510 from sliding excessively and abutting against the shaft 200; the second position-limiting portion is located between the second slider 520 and the shaft 200, and the second position-limiting portion is used for limiting the sliding distance of the second slider 520 so as to prevent the second slider 520 from sliding excessively and abutting against the shaft 200. The limiting part can be a stop block, a limiting screw and other parts which can be used as limiting barriers.

In some embodiments, the flexible glue connection band 320 may be provided with a plurality of retractable stoppers, the retractable stoppers are spaced apart from each other at different positions of the flexible glue connection band 320, and the electronic device 20 may control the retractable stoppers to extend out of the surface of the flexible glue connection band 320 or retract into the flexible glue connection band 320. The user can select the expansion size of the expansion part 312, for example, select 20% expansion, 50% expansion, or 100% expansion, and the electronic device 20 controls the corresponding retractable stop to extend out of the surface of the soft rubber connecting band 320 according to the expansion size selected by the user, so as to stop the soft rubber connecting band 320 from moving further, and further control the expansion size of the expansion part 312. Compared with a winding drum type flexible screen in the related art, the expansion size of the display screen can be freely selected by a user according to the requirement of the user, and the display screen is more intelligent and humanized.

It should be noted that the structure of the first sliding member 510 is not limited to this, for example, when the size of the soft rubber connection band 320 is equal to the size of the extension portion 312, the soft rubber connection band is not provided on the main body portion 311. The first sliding member 510 may include a sliding rail structure and a sliding structure capable of sliding along the sliding rail structure, and the first sliding member 510 may be made of a rigid material, such as wear-resistant and relatively rigid race steel or a metal material. The outer surface of the slide rail structure is flush with the outer surface of the soft rubber connecting band 320, and the slide rail structure is provided with a bulge or a groove which is the same as the second limiting structure in structure, so that the slide structure can slide to the soft rubber connecting band 320 from the slide rail structure.

It should be noted that, when the first supporting sheet 330 is a rigid sheet having a mesh 334 structure, the friction coefficient of the second protective layer 420 is relatively small, so that the first sliding member 510 and the second sliding member 520 can directly slide along the surface of the second protective layer 420, and the friction force on the second protective layer 420 during the sliding process of the first sliding member 510 and the second sliding member 520 can also be reduced, thereby reducing the wear of the second protective layer 420.

As shown in fig. 17 and 18, fig. 17 is a schematic structural diagram of the shaft, the driving motor and the central shaft of the flexible screen assembly shown in fig. 2, and fig. 18 is a schematic structural diagram of the shaft, the driving motor and the central shaft of the flexible screen assembly and the driving motor shown in fig. 2. The electronic device 20 may further include a driving motor 600, the driving motor 600 is connected to the shaft 200, and the driving motor 600 may drive the shaft 200 to rotate, so as to drive the soft glue connecting band 320 to move toward the outside of the casing 100 or the inside of the casing 100. For example, the shaft 200 is provided with a through hole 220, a plurality of clamping grooves 221 are formed in a wall of the through hole 220, an output shaft 610 of the driving motor 600 is provided with a plurality of clamping teeth 611, the clamping teeth 611 can be meshed with the clamping grooves 221 so that the driving motor 600 is connected with the shaft 200, and the driving shaft is driven by the driving motor 600 to rotate so as to drive the shaft 200 to rotate around the driving motor 600. It can be understood that the driving motor 600 and the shaft 200 may jointly form a belt wheel type motor device, and the shaft 200 rotates around the driving motor 600, compared with the case that the driving motor 600 is disposed outside the shaft 200, the embodiment of the present application may save the occupied space of the driving motor 600 for the electronic device 20. Of course, it is also possible to arrange the driving motor 600 outside the shaft 200 and to arrange a fixing member inside the shaft 200, around which the driving shaft 200 is driven by the driving motor 600.

When the driving shaft 200 is driven by the driving motor 600 to rotate clockwise, the soft rubber connecting band 320 moves around the outer surface of the shaft 200 towards the direction outside the casing 100 under the driving of the shaft 200, so that the expansion part 312 is gradually expanded outside the casing 100; when the driving shaft 200 of the driving motor 600 rotates counterclockwise, the soft rubber connecting band 320 moves toward the inside of the casing 100 around the outer surface of the shaft 200 under the driving of the shaft 200, so that the expanded portion 312 is gradually recovered to the inside of the casing 100. The electronic device 20 can also control the rotation time of the shaft 200 by controlling the working time of the driving motor 600, and further control the movement distance of the extension portion 312, so that the size of the extension portion 312 expanded outside the housing 100 can be adjusted, the playing interest is higher, and the user experience is improved.

As shown in fig. 19 and 20, fig. 19 is a third schematic structural diagram of the electronic device according to the embodiment of the present application, and fig. 20 is a schematic structural diagram of a driving apparatus in the electronic device shown in fig. 19. The electronic device 20 may further include a driving device 700, and the driving device 700 is configured to drive the shaft 200 to reciprocate along the direction of the housing 100, so as to engage and disengage the shaft 200 with and from the housing 100.

Wherein, the pushing mechanism 720 may include a transmission component such as a transmission component 721 and a pushing component such as a pushing component 722, the transmission component 721 is connected with the first motor 710, one end of the pushing component 722 is connected with the transmission component 721, and the other end of the pushing component 722 is connected with the shaft 200. The first motor 710 is used to drive the transmission assembly 721 to move, so that the pushing assembly 722 connected with the transmission assembly 721 moves along with the transmission assembly 721, and further, the pushing assembly 722 moves along the direction parallel to the housing 100. The driving assembly 721 may be a combination of one or more of a screw driving assembly, a gear set, or a telescopic assembly, wherein the telescopic assembly may include an electric push rod, an electro-hydraulic push rod, a pneumatic push rod, or a hydraulic push rod.

The push assembly 722 can include a first base, such as the first base 7221, and a push rod, such as the push rod 7222. Wherein, the first base 7221 is fixed on the inner surface of the housing 100, the first base 7221 is provided with a sliding groove, and the push rod 7222 is disposed in the sliding groove and slidably connected with the sliding groove so that the push rod 7222 can slide in the sliding groove. One end of the push rod 7222 is connected to the transmission assembly 721 and the other end of the push rod 7222 is connected to the shaft 200.

For another example: the electronic device 20 may control the output shaft of the first motor 710 to rotate reversely (or forward), so that the transmission assembly 721 connected to the output shaft of the first motor 710 moves along with the output shaft of the first motor 710, the transmission assembly 721 drives the push rod 7222 to move in a direction close to the housing 100 during the movement, the shaft 200 connected to the push rod 7222 moves along with the movement of the push rod 7222, the shaft 200 also moves in a direction close to the housing 100, and the shaft 200 is retracted into the housing 100 from the outside of the housing 100, thereby realizing the engagement between the shaft 200 and the housing 100.

The outer surface of the push rod 7222 is further provided with an elastic member such as an elastic member 7223, and the elastic member 7223 may be a spring or other member having elasticity. The elastic member 7223 may be configured to support and protect the push rod 7222, for example, when the electronic device 20 falls, the elastic member 7223 may play a role in buffering, so as to reduce an instant impact force applied to the push rod 7222, further reduce an impact force applied to the transmission assembly 721 connected to the push rod 7222, and protect the transmission assembly 721 from being damaged.

With continued reference to fig. 20, the transmission assembly 721 may include a second base 7211, a transmission screw 7212 and a connecting member 7213, wherein the second base 7211 is fixed to the housing 100.

Referring to fig. 21, fig. 21 is a schematic structural view of a connecting member in the driving device shown in fig. 20. The transmission assembly 721 may further include a guide rod such as the guide rod 7214, the guide rod 7214 is disposed on the second base 7211, for example, both ends of the guide rod 7214 may be directly inserted into the coupling holes of the second base 7211.

It will be appreciated that rotation of the drive screw 7212 can be translated into linear motion of the coupling 7213.

As shown in fig. 22 and 23, fig. 22 is a fourth schematic structural diagram of the electronic device according to the embodiment of the present application, and fig. 23 is a schematic structural diagram of a driving apparatus in the electronic device shown in fig. 22. The transmission assembly 721 may also be a gear assembly, for example, the transmission assembly 721 may include a gear such as a gear 7215, the gear 7215 may be disposed on an output shaft of the first motor 710, and the first motor 710 may drive the gear 7215 to rotate.

It should be noted that the transmission assembly 721 may also include a plurality of gears, and the reciprocal motion of the push rod 7222 is driven by the mutual transmission of the plurality of gears.

Referring to fig. 3, fig. 22, and fig. 24, fig. 24 is a fifth schematic structural diagram of an electronic device according to an embodiment of the present application. The electronic device 20 may further include a second motor 800, the second motor 800 is connected to the soft adhesive connection band 320, and the second motor 800 may be configured to drive the soft adhesive connection band 320 to move along with the relative movement between the housing 100 and the shaft 200, so as to recycle a portion of the flexible screen assembly 300 into the housing 100 or unfold a portion of the flexible screen assembly 300 outside the housing 100, so as to increase the display area of the electronic device 20.

When the driving device 700 drives the shaft 200 to move in a direction away from the casing 100, the second motor 800 may drive the soft adhesive tape 320 to move along the shaft 200 after a preset interval time, so that the extension portion 312 originally stored in the casing 100 slowly slides along the outer surface of the shaft 200 and gradually expands outside the casing 100 (or outside the electronic device 20) as shown in fig. 3, and further expands the extension portion 312 outside the electronic device 20, and the main portion 311 and the extension portion 312 may jointly display one screen or two screens, respectively, and compared with a case where only the main portion 311 is used for displaying in an initial state, the extension portion 312 expands outside the casing 100, and the display area of the electronic device 20 may be increased.

In the embodiment of the application, the two driving devices are arranged to control the motion states of the shell 100, the shaft 200 and the soft rubber connecting band 320 respectively, so that the display area of the flexible screen assembly 300 can be selected. Compared with the display screen with a fixed installation space in the related art, the embodiment of the application can increase the display area of the electronic device 20 without additionally increasing the installation space of the flexible screen assembly 300 (or the display screen).

With continued reference to fig. 22 and 24, the second motor 800 is used to drive the soft gum connecting band 320 to curl or stretch so that the expansion portion 312 is received in the casing 100 or is unfolded outside the casing 100. For example, one end of the soft adhesive tape 320 is wound around the output shaft of the second motor 800, and the other end of the soft adhesive tape 320 is connected to the housing 100, and compared with the case in which the flexible screen assembly 300 is directly connected to the second motor 800 and the housing 100, the embodiment of the present application can transfer the stretching object to the soft adhesive tape 320, and can reduce the damage degree of the flexible screen assembly 300 in the stretching process.

When the electronic device 20 needs to control the flexible screen assembly 300 to be unfolded outside the housing 100, the electronic device 20 may control the second motor 800 to drive the flexible glue connection band 320 to gradually change from the curled state to the extended state, so that the extension portion 312 may slide along the outer surface of the shaft 200 toward a direction away from the second motor 800, so as to gradually unfold the extension portion 312 originally housed inside the housing 100 outside the electronic device 20 (or the housing 100), and display a picture together with the main body portion 311 originally exposed outside the electronic device 20.

When the electronic device 20 needs to control the flexible screen assembly 300 to be accommodated in the housing 100, the electronic device 20 may control the second motor 800 to drive the soft adhesive connecting band 320 to gradually change from the extended state to the curled state, so that the flexible screen assembly 300 may slowly slide along the outer surface of the shaft 200 toward a direction close to the second motor 800, so as to gradually recover the extension portion 312 originally deployed outside the electronic device 20 (or the housing 100) into the housing 100.

Wherein, the size of extension 312 is less than or equal to the size of casing 100 for extension 312 can expand completely when accomodating in casing 100, need not to curl, and for the display screen that needs curl among the relevant art, this application embodiment can avoid because the flexible screen often curls and easily damages, can prolong the life of flexible screen.

When the driving device 700 drives the housing 100 and the shaft 200 to move relatively, if the second motor 800 and the driving device 700 move simultaneously, the flexible screen assembly 300 may be loosened, which may cause undesirable phenomena such as wrinkles or unevenness of the flexible screen assembly 300, and further affect the image display effect of the electronic device 20.

As shown in fig. 25, fig. 25 is a sixth schematic structural diagram of an electronic device according to an embodiment of the present application. In order to keep the flexible screen assembly 300 in a tightened state all the time and ensure the tension of the flexible screen assembly 300, a processor such as the processor 900 of the electronic device 20 according to the embodiment of the present application is electrically connected to the driving device 700 and the second motor 800, and the processor 900 may be configured to drive the driving device 700 to drive the housing 100 and the shaft 200 to move relatively at different times and the second motor 800 to drive the soft adhesive connecting tape 320 to move along with the relative movement of the housing 100 and the shaft 200, so that the driving device 700 and the second motor 800 are driven in different steps and different times. It can be understood that there is a time difference between the driving time of the driving device 700 and the driving time of the second motor 800, and the time difference is very short, and the time difference is mainly used to ensure that the two ends of the flexible screen assembly 300 are always in a stressed and tightened state, ensure the tension of the flexible screen assembly 300, and ensure that undesirable phenomena such as wrinkles and unevenness do not occur, so that the picture display effect of the electronic device 20 is not affected by the movement of the flexible screen assembly 300.

For example, when it is desired to deploy the extension portion 312, the processor 900 may control the driving device 700 to drive the shaft 200 to move away from the housing 100 at a first time T1, so that the shaft 200 slowly extends out of the housing 100 to achieve separation of the housing 100 and the shaft 200. When the shaft 200 moves to the second time T2, the processor 900 controls the second motor 800 to drive the soft glue link 320 to unfold slowly, so that the extension 312 of the flexible screen assembly 300 can slide along the outer surface of the shaft 200 to the outside of the housing 100. The first time T1 is earlier than the second time T2, for example, T2 is T1+ T1, and T1 is a first preset interval time, which may be set according to practical situations, and the embodiment of the present application is not limited thereto. It can be understood that, when the extension part 312 is unfolded, the shaft 200 moves earlier than the soft rubber connection band 320, so that the soft rubber connection band 320 is always in a stretched state, and further, the flexible screen assembly 300 is always in a stretched state in the process that the extension part 312 is gradually unfolded outside the housing 100.

When the extension part 312 needs to be recovered into the casing 100, the processor 900 may control the second motor 800 to drive a part of the soft adhesive tape 320 to be slowly curled at a third time T3, and the soft adhesive tape 320 drives the extension part 312 to move toward the direction close to the second motor 800 in the curling process. When flexible screen assembly 300 moves to a fourth time T4, processor 900 controls driving device 700 to drive shaft 200 to move away from housing 100, such that shaft 200 is slowly retracted into housing 100 to achieve the engagement between housing 100 and shaft 200. The third time T3 is earlier than the fourth time T4, for example, T4 is T3+ T2, and T2 is a second preset interval time, which may be set according to practical situations, which is not limited in the embodiment of the present application. It can be understood that, when the extension part 312 is retracted, the soft adhesive connecting band 320 moves earlier than the shaft 200, so that the soft adhesive connecting band 320 is always in a stretched state, and further the flexible screen assembly 300 is always in a stretched state in the process that the extension part 312 is gradually retracted into the housing 100.

In other embodiments, the processor 900 may also control the driving device 700 and the second motor 800 according to the tension value of the soft gum connecting band 320. For example, a tension detector may be disposed on the soft rubber connection band 320, and the tension detector is configured to detect a tension value of the soft rubber connection band 320. When the extension part 312 needs to be unfolded, the processor 900 first controls the driving device 700 to start, obtains the first tension value of the soft gum connecting band 320 detected by the tension detector, and controls the second motor 800 to start when the first tension value of the soft gum connecting band 320 is greater than the first preset tension value. Similarly, when the extension part 312 needs to be recovered, the processor 900 first controls the second motor 800 to start, and obtains the second tension value of the soft adhesive tape 320 detected by the tension detector, and controls the driving device to start when the second tension value of the soft adhesive tape 320 is greater than the second preset tension value. The starting time of the driving device 700 and the second motor 800 is determined according to the magnitude of the tension value of the soft rubber connecting band 320, so that the situation that the flexible screen assembly 300 is folded due to the fact that the tension value of the soft rubber connecting band 320 is too small due to too small starting time interval of the two can be avoided, and the situation that the soft rubber connecting band 320 is damaged due to too large tension value due to too large starting time interval of the two can also be avoided. Compared with the starting control of two driving devices according to a fixed time interval, the control of the embodiment of the application is more accurate and intelligent.

In the above embodiment, alternatively, the electronic device 20 may be provided with only the driving device 700 and not the second motor 800, such as shown in fig. 26, where fig. 26 is a seventh structural schematic diagram of the electronic device provided in the embodiment of the present application. One end of the soft rubber connecting band 320 is connected with the shell 100, the other end of the soft rubber connecting band 320 is connected with the driving device 700, the driving device 700 drives the shell 100 and the shaft 200 to move relatively and drives the soft rubber connecting band 320 to move, so that the extension part 312 extends out of the shell 100, and the extension part 312 and the main body part 311 can display pictures together.

As shown in fig. 27 and 28, fig. 27 is a schematic structural diagram of a driving device in the electronic apparatus shown in fig. 26, and fig. 28 is a schematic structural diagram of a pushing assembly in the driving device shown in fig. 26. The push rod 7222 includes a support portion 7222a, a rotation shaft 7222b and a push portion 7222c, one end of the push portion 7222c is fixed on the support portion 7222a, the other end of the push portion 7222c is connected with the shaft 200, the rotation shaft 7222b is arranged at one end of the support portion 7222a far from the shaft 200, and the rotation shaft 7222b is in transmission connection with the soft rubber connecting band 320. For example, the soft rubber connection band 320 is sleeved on the rotation shaft 7222b and is fixedly connected with the housing 100 at two ends of the soft rubber connection band 320.

When the extension part 312 needs to be unfolded, the processor 900 may control the first motor 710 to drive the transmission assembly 721 to move, the transmission assembly 721 drives the pushing assembly 722 to move towards the direction away from the casing 100, the pushing assembly 722 pushes the shaft 200 to move towards the direction away from the casing 100 through the pushing portion 7222c in the moving process, meanwhile, as the rotating shaft 7222b also moves towards the direction away from the casing 100, the soft rubber connecting band 320 also moves towards the direction away from the casing 100 along with the rotating shaft 7222b and slides along the outer surface of the rotating shaft 7222b, so as to increase the extension length of the soft rubber connecting band 320, and the extension part 312 slides outside the casing 100 under the driving of the soft rubber connecting band 320, so that the extension part 312 is exposed outside the electronic device 20.

When the extension part 312 needs to be recovered, the processor 900 may control the first motor 710 to drive the transmission assembly 721 to move, the transmission assembly 721 drives the pushing assembly 722 to move toward the direction close to the casing 100, the pushing assembly 722 pulls the shaft 200 to move toward the direction close to the casing 100 through the pushing portion 7222c in the moving process, and meanwhile, as the rotating shaft 7222b also moves toward the direction close to the casing 100, the soft rubber connecting band 320 also slides along the outer surface of the rotating shaft 7222b along the direction close to the casing 100 along with the rotating shaft 7222b, so as to reduce the extension length of the soft rubber connecting band 320, and the extension part 312 slides into the casing 100 under the driving of the soft rubber connecting band 320, so that the extension part 312 is recovered into the casing 100.

It should be noted that, in the process of expanding the expansion portion 312 of the flexible screen assembly 300 out of the casing 100 or retracting the expansion portion into the casing 100, the flexible screen assembly 300 keeps a stretched state under the combined action of the shaft 200 and the soft adhesive connecting band 320, so as to ensure that the image display effect of the electronic device 20 is not affected.

In order to avoid the excessive friction between the soft rubber connecting band 320 and the rotating shaft 7222b and the excessive damage of the tension of the soft rubber connecting band 320, the rotating shaft 7222b in the embodiment of the application can rotate, for example, the rotating shaft 7222b is sleeved on the outside of the fixed shaft 7222d, and can be rotatably connected with the fixed shaft 7222d to enable the rotating shaft 7222b to rotate around the fixed shaft 7222d, so that the rotating shaft 7222b can be driven to rotate when the soft rubber connecting band 320 moves, and then the friction between the soft rubber connecting band 320 and the rotating shaft 7222b can be reduced, and the soft rubber connecting band 320 can move more smoothly. And the rotating shaft 7222b may also constitute a combined rolling mechanism with the shaft 200, thereby ensuring smooth retraction and unfolding of the flexible screen assembly 300.

It can be understood that, in the embodiment of the present application, the first motor 710 provides an active driving effect, the shaft 200 and the rotating shaft 7222b are a linkage mechanism, and perform linkage motion under the active driving of the first motor 710, so that the motion distance of the pushing portion 7222c, the expansion length of the expansion portion 312, and the motion distance of the flexible glue connecting band 320 are equal, and further it is ensured that the flexible screen assembly 300 is in a constantly tightened state (it is ensured that the tension of the flexible screen assembly 300 is within a certain range) in the expanding process and the recovering process, and abnormal situations such as too large tension of the flexible screen assembly 300 being damaged or too small tension of the flexible screen assembly 300 being wrinkled due to asynchronous expanding are avoided.

In the embodiment of the present application, the relative movement between the housing 100 and the shaft 200 and the unfolding and folding of the flexible screen assembly 300 can be realized through the driving device 700, and compared with the embodiment of the above application, one driving device can be reduced, and the structure of the electronic device 20 can be simplified on the basis of the embodiment of the above application.
