In the exemplary configuration of fig. 1, the electronic device 20 is a portable device, such as a cellular telephone, media player, tablet, or other portable computing device. Other configurations may be used for electronic device 20 if desired.

The example of fig. 1 is merely exemplary.

Referring to fig. 1 and fig. 2, fig. 2 is a schematic view of a combined structure of a shaft, a driving motor, a connection belt and a flexible screen according to an embodiment of the present application. The electronic device 20 may include a housing, such as housing 100, and the housing 100 may be formed of plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The housing 100 may be formed using a unitary configuration in which some or all of the housing 100 is machined or molded as a single structure, or may be formed using multiple structures (e.g., an inner frame structure, one or more structures forming an outer housing surface, etc.).

The case 100 may have a regular shape, such as a rectangular parallelepiped structure, a rounded rectangular structure, among others. The housing 100 may have a plurality of sides, and adjacent sides are connected to each other to form a corner. The number of sides may be three, for example, the housing 100 may include a first side, a second side, and a third side, where the first side is disposed opposite to the third side, one end of the second side is connected to one end of the first side, and the other end of the second side is connected to one end of the third side. It should be noted that the housing 100 may be irregularly shaped, and the number of sides may be four, five, or six.

The electronic device 20 may include a limiting member movably connected with the housing 100, such that the limiting member may move relative to the housing 100, for example, the limiting member may be disposed between the first side and the third side, one end of the limiting member may be movably connected with the other end of the first side, and the other end of the limiting member may be movably connected with the other end of the third side, so that the limiting member may reciprocate along a direction parallel to the housing 100. The limiting piece can be in a regular shape, such as a cylindrical structure or a semi-cylindrical structure, or in an irregular shape, such as an arc surface on one surface of the limiting piece, a flat surface or a wavy surface on the other surface, and the like. The stopper may be an additional component independent of the housing 100, or may be a part of the housing 100.

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

The shaft 200 may be a cylindrical structure, and the outer surface of the shaft 200 may be further provided with a first limiting structure such as a first limiting structure, which may be a ring-shaped structure disposed around the circumference of the outer surface of the shaft 200. The number of the first limiting structures can be multiple, the first limiting structures are arranged at intervals, and the number of the first limiting structures can also be one. The first limiting structure may be a protruding structure disposed on the outer surface of the shaft 200 and protruding from the outer surface of the shaft 200, or may be a groove structure disposed on the outer surface of the shaft 200, or when the first limiting structure is plural, a part of the first limiting structure may be a protruding structure, and another part of the first limiting structure may be a groove structure. It should be noted that, the shaft 200 may have an irregular structure, for example, a portion of the surface of the shaft 200 has an arc-shaped structure, and a portion of the surface has a square-shaped structure.

Referring to fig. 3, fig. 3 is a schematic diagram of a second structure of the electronic device according to the embodiment of the present application. The electronic device 20 may also 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 and a wide screen mode as shown in fig. 3, in which the display area of the flexible screen assembly 300 is fixed; in the wide screen mode, the display area of the flexible screen assembly 300 is expandable. For example, the flexible screen assembly 300 may include a flexible display module 310 and a deformable support member positioned on a non-display side of the flexible display module 310 for supporting the flexible display module 310. It can be appreciated that the structural strength of the support member is higher, so that the flexible display module 310 can be supported on one hand, the flatness of the flexible display module is improved, the flexible display module 310 is not easy to collapse or fold in the display process, and on the other hand, the overall strength of the flexible screen assembly 300 can be improved by the support member, 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 organic light emitting diode) module, which may include a display substrate and an encapsulation material, wherein an organic light emitting object is encapsulated between the display substrate and the encapsulation material, and the OLED module includes a plurality of OLED units, where each OLED unit is electrically connected to a motherboard of an electronic device, so as to realize self-luminescence and display a picture. The flexible display module 310 may also be an LCD (Liquid Crystal Display liquid crystal display) module, which may include a display substrate and a packaging material, in which a liquid crystal material is encapsulated between the display substrate and the packaging material, and a main board of the electronic device provides a voltage to the liquid crystal material, so as to change an arrangement direction of liquid crystal molecules, and after light projected from a backlight source is jointly acted inside the LCD module, an image is formed in a display area 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 being disposed on the housing 100, the extension portion 312 being movable with respect to the housing 100 such that the extension portion 312 may be unfolded outside the housing 100 or recycled inside the housing 100. The expanding portion 312 can deform during movement to switch between a bent state and a flat state, and the limiting member is located at the bent position of the expanding portion 312 and abuts against the supporting member, so that the limiting member and the supporting member can together support the bent position of the expanding portion 312.

With continued reference to fig. 2, the support member may further include a flexible adhesive connecting band such as flexible adhesive connecting band 320320, wherein the flexible adhesive connecting band 320 has a hardness (shore a) of (60-75), such as 65, 68, 70, 75, etc. The flexible glue joint band 320 may be made of rubber, silicone rubber, TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber), or the like. The flexible glue connection strip 320 is disposed on the non-display surface of the extension portion 312, and the flexible glue connection strip 320 can provide a flat bearing surface for the extension portion 312, so that the extension portion 312 can be unfolded flatly, and no adverse phenomena of wrinkling or recessing occur. And compared with the rigid material, the soft rubber connecting belt 320 adopted in the embodiment of the application has the hardness of between 60 and 75 degrees, so that the damage to the expansion part 312 in the moving process of the soft rubber connecting belt 320 can be reduced, and the contact surface of the expansion part 312 and the soft rubber connecting belt 320 is further protected from being worn easily. In addition, since the expansion portion 312 often rubs against the shaft 200 during movement, the expansion portion 312 is easily broken. In the embodiment of the application, the soft rubber connecting belt 320 is additionally arranged on the expansion part 312 needing to move, so that the friction force originally acting on the expansion part 312 can be transferred to the soft rubber connecting belt 320, and the expansion part 312 can be further protected.

The flexible glue connection strip 320 is provided with a second limit structure, such as a second limit structure, which is disposed on a side of the flexible glue connection strip 320 away from the extension portion 312, and the second limit structure may be matched with the first limit structure. Such as: when the first limiting structure is a protruding structure, the second limiting structure may be a groove structure, at this time, the first limiting structure may be accommodated in the second limiting structure and connected with the second limiting structure in an interference fit manner, so that the flexible glue connecting band 320 moves according to a preset movement track (such as moves linearly along a direction parallel to the housing 100) under the limiting actions of the first limiting structure and the second limiting structure, and further, the extension portion 312 moves to the outside of the housing 100 or the inside of the housing 100 according to the preset movement track. For another example: when the first limit structure is a groove structure, the second limit structure can be a protruding structure, and the second limit structure can be contained in the first limit structure and is in interference fit connection with the groove wall of the first limit structure. Also, for example: when the number of the first limiting structures is multiple and part of the first limiting structures are protruding structures and 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 flexible glue connecting band 320, wherein part of the second limiting structures are matched with the protruding structures, and part of the second limiting structures are matched with the groove structures. It can be appreciated that the first limiting structure and the second limiting structure are matched and abut against each other, so as to limit the movement path of the flexible glue 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 so as to be exposed outside the electronic device 20, and the extension portion 312 is in the storage state, and the extension portion 312 is hidden inside the housing 100 and cannot be used for displaying information, and is only displayed through the main body portion 311 of the flexible screen assembly 300; when the flexible screen is switched from the narrow screen mode to the wide screen mode, the user can pull the shaft 200 to move in a direction away from the housing 100 (or can set the driving mechanism to drive the shaft 200 to move), and the shaft 200 can drive at least a part of the expansion portion 312 to gradually rotate out of the housing 100 along the outer surface of the shaft 200 during the movement, at least a part of the expansion portion 312 is exposed out of the housing 100, so that the narrow screen mode is switched to the wide screen mode. The extended portion 312 exposed to the outside can display information together with the main body portion 311, and the display area can be increased relative to 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 expansion portion 312 may be gradually rotated into the interior of the housing 100 along the outer surface of the shaft 200 in a direction approaching the housing 100 (the expansion or storage of the flexible screen assembly 300 may be achieved by manual driving or mechanical driving), so that at least a portion of the expansion portion 312 is stored in the housing 100 only, and the shaft 200 may be moved in a direction toward the housing 100 during the movement of the expansion portion 312, thereby shortening the distance between the shaft 200 and the housing 100 (or the reciprocating movement of the shaft 200 may be driven by mechanical driving).

According to the embodiment of the application, the flexible glue connecting band is arranged on the expansion 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 is still through the mutually supporting of first limit structure and second limit structure for flexible screen subassembly 300 is according to predetermineeing the motion orbit and is expanded outside casing 100 or accomodate in casing 100, compares in the correlation technique, and this application embodiment can be so that the expansion in-process of flexible screen subassembly 300 does not take place the skew, and then makes flexible screen subassembly 300 do not take place to pull at electronic equipment 20's length direction, further protects flexible screen subassembly 300 not damaged.

As shown in fig. 4, fig. 4 is a schematic side view of a first type of side structure of the shaft and flexible screen assembly of fig. 2. The size of the flexible adhesive tape 320 is equal to the size of the extension portion 312, and the projection of the flexible adhesive tape 320 on the flexible screen assembly 300 is located on the extension portion 312, so that the flexible adhesive tape 320 can cover the non-display surface of the whole extension portion 312, thereby protecting the whole extension portion 312. Compared with the prior art, the flexible screen is directly used as a stretching main body, and the flexible glue connecting belt 320 is arranged on the expansion part 312, so that the expansion part 312 can be in direct contact with the shaft 200 at intervals, and further abrasion to the expansion part 312 in the process that the non-display surface of the expansion part 312 is directly rubbed with the outer surface of the shaft 200 is avoided.

As shown in fig. 5, fig. 5 is a schematic view of a second side structure of the shaft and flexible screen assembly of fig. 2. The size of the flexible glue joint band 320 may also be larger than the size of the extension 312. When the size of the flexible adhesive connection tape 320 is larger than the size of the extension portion 312, a part of the projection of the flexible adhesive connection tape 320 on the flexible screen assembly 300 is located at the extension portion 312, and a part of the projection of the flexible adhesive connection tape 320 is located outside the extension portion 312, for example, may be located on the main body portion 311 or may be located in the accommodating space of the housing 100, for example, may be used for connecting a driving motor, which drives the extension portion 312 to be unfolded or recovered by driving the portion of the flexible adhesive connection tape 320 located in the accommodating space of the housing 100 to be curled or stretched.

When a portion of the flexible adhesive connecting tape 320 is positioned at the main body portion 311, the side outer surface of the flexible adhesive connecting tape 320 is flush with the side outer surface of the main body portion 311. For example, the flexible glue connection strap 320 and the main body portion 311 are both in a cuboid structure, the flexible glue connection strap 320 may have four sides connected to each other, and the flexible glue connection strap 320 has two opposite surfaces, and the two surfaces are connected to two sides of the four sides so as to enclose and form a cuboid structure. Similarly, the main body 311 may also have four interconnected sides and opposite display and non-display surfaces, where the flexible adhesive tape 320 is disposed on the non-display surface of the main body 311, the four outer surfaces of the sides of the flexible adhesive tape 320 are flush with the four outer surfaces of the sides of the main body 311, and the flexible adhesive tape 320 may support the main body 311, so that the display surface of the main body 311 is smoother, and the flexible adhesive tape 320 is not observed from the outside, thereby maintaining the simplicity of the appearance of the flexible screen assembly 300.

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 direction P1-P1. The first limiting structure includes a first limiting groove 210, the first limiting groove 210 is disposed around the outer surface of the shaft 200, and the groove width of the first limiting groove 210 is gradually narrowed 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, wherein the first limiting protrusion 321 is arranged on the outer surface of the flexible glue connecting band 320 and protrudes out of the surface of the flexible glue connecting band 320, the outer surface of the flexible glue connecting band 320 is far away from one surface of the flexible screen assembly 300, and the inner surface of the flexible glue connecting band 320 is connected with the non-display surface of the flexible screen assembly 300. The material of the first limiting protrusion 321 is the same as that of the flexible adhesive connecting strip 320, for example, the first limiting protrusion 321 is made of rubber, and the width of the first limiting protrusion 321 gradually widens from the inner surface of the flexible adhesive connecting strip 320 toward the outer surface of the flexible adhesive connecting strip 320, so that the shape of the first limiting protrusion 321 can be matched with the shape of the first limiting groove 210, the first limiting protrusion 321 can be embedded into the first limiting groove 210, and the first limiting protrusion 321 can limit the movement track of the flexible screen assembly 300 through the first limiting groove 210, so that the expansion part 312 moves into the casing 100 or out of the casing 100 according to the preset track. The first spacing protruding 321 is connected with the first spacing groove 210 in an interference fit manner, for example, the size of the first spacing protruding 321 is slightly larger than the size of the first spacing groove 210, so that when the first spacing protruding 321 is installed in the first spacing groove 210, the outer surface of the first spacing protruding 321 and the groove wall of the first spacing groove 210 are mutually extruded, so as to increase the abutting firmness of the first spacing groove 210 and the first spacing protruding 321, and further increase the friction coefficient between the shaft 200 and the flexible glue connecting belt 320, and an effective friction area is formed between the shaft 200 and the flexible glue connecting belt 320. It will be appreciated that if the friction coefficient between the shaft 200 and the flexible adhesive tape 320 is too small, the flexible adhesive tape 320 may slip during the movement around the shaft 200, so that the expansion portion 312 may not be smoothly expanded and stored. According to the embodiment of the application, the flexible glue connecting band 320 can be prevented from sliding easily through the first limiting groove 210 and the first limiting protrusion 321, and therefore the display reliability of the flexible screen assembly 300 is guaranteed. The shape of the first limiting groove 210 is not limited to this, and for example, the first limiting groove 210 may be a dovetail groove, a square groove, or the like.

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

The support may further include a first support sheet 330, the first support sheet 330 being a rigid structure, for example, the first support sheet 330 may be made of a metal material, such as a steel sheet, an aluminum sheet, a copper sheet, or the like, for example, the first support sheet 330. The first supporting piece 330 may also be made of rubber material or silica gel material. The first supporting sheet 330 is embedded into the flexible adhesive connecting band 320, for example, a mode of forming the flexible adhesive connecting band 320 by injection molding of the first supporting sheet 330 can be adopted, so that the first supporting sheet 330 is wrapped in the flexible adhesive connecting band 320, and then the first supporting sheet 330 is not directly contacted with the flexible screen assembly 300, and the purpose of protecting the flexible screen assembly 300 is achieved.

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

For example, the first support piece 330 may include a first side 331, a second side 332, and a recess 333, the recess 333 being located between the first side 331 and the second side 332, the first side 331 being located at one end of the shaft 200, the second side 332 being located at the other end of the shaft 200, the recess 333 being located at an intermediate position of the shaft 200. Wherein the recess 333 is curved in a direction away from the flexible display module 310. It will be appreciated that the structure of the first support sheet 330 is similar to that of a tape measure, the first support sheet 330 has an arcuate structure in cross section along the width of the electronic device 20, and the bending direction of the first support sheet 330 faces away from the axis 200. The first support piece 330 may be deformed to switch the recess 333 between the first bent state and the second bent state during the movement of the flexible adhesive connection strip 320 along the outer surface of the shaft 200.

For example, when the first supporting sheet 330 is in the first state, the recess 333 is in the first curved state, which refers to a state of being curved in a direction away from the flexible display module 310. When the flexible glue connection belt 320 moves along the shaft 200, the flexible glue connection belt 320 moving to the position of the shaft 200 will abut against the shaft 200, and during this process, the first supporting sheet 330 located inside the flexible glue connection belt 320 may receive a force along the radial direction of the shaft 200 through the flexible glue connection belt 320 and deform, so that the recess 333 is switched from the first bending state to the second bending state, and the remaining portions of the first supporting sheet not abutting against the shaft 200 remain unchanged, i.e. are in the first bending state. The second bending state refers to a state that the recess 333 is bent towards a direction close to the flexible display module 310, so that the bending direction of the first supporting sheet 330 is the same as the radian of the shaft 200, and the fitting degree of the flexible glue connecting band 320 and the shaft 200 is further improved, so that the movement of the flexible glue connecting band 320 is more stable. When the flexible glue connection strip 320 moves gradually out of the housing 100 or into the housing 100 along the outer surface direction of the shaft 200, the flexible glue connection strip originally abutting against the shaft 200 is gradually away from the shaft 200, and the pressing force of the shaft 200 to the first supporting piece 330 is gradually removed, so that the recess 333 is switched from the second bending state to the first bending state.

It will be appreciated that in the first state of the first support sheet 330, the cross-sectional shape of the first support sheet 330 is as shown in fig. 10, and the first support sheet 330 is concave in the first state, and only needs to be pushed against the back surface thereof with a little force, so that the first support sheet 330 can be deformed and turned to be straight, so that the shape of the first support sheet 330 is the same as the shape of the expansion portion 312, and the expansion portion 312 can move along the surface of the shaft 200. Based on the structure of the first support piece 330, the first support piece 330 can deform when receiving the force along the radial direction of the shaft 200, and can be turned from a concave shape to a flat shape, as shown in fig. 11; and resumes 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 piece 330 is not limited to this, for example, the first supporting piece 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 expanding portion moves onto the shaft 200, all or part of the concave portions 333 deform when receiving a force along a 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 direction of the main body portion, and at this time, the plurality of concave portions 333 switch from the first bending state to the second bending state. When the extension 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 will be appreciated that if the first supporting piece 330 is a rigid structure with a generally flat shape, when the first supporting piece 330 moves to the position of the shaft 200, the first supporting piece 330 is deformed into a bent state due to the interaction force between the shaft 200 and the first supporting piece 330, so that the first supporting piece 330 is attached to the outer surface of the shaft 200, when the first supporting piece 330 leaves the position of the shaft 200, the interaction force between the shaft 200 and the first supporting piece 330 disappears, but because the first supporting piece 330 is a rigid structure with a generally flat shape, the original flat shape cannot be restored without other action force after the deformation, for example, the original bent state can be presented, so that the expansion portion 312 can be presented in an uneven condition, and the display effect of the electronic device 20 is affected. The recess 333 of the present application may be switched between the first bending state and the second bending state, so that when the shaft 200 is in the position (or in the bending position), the recess is switched from the first bending state to the second bending state, and when the recess moves to other positions, the recess is switched from the second bending state back to the first bending state, so that the free switching of the extension portion 312 between the extended state and the retracted state can be realized, and the extension portion 312 can be kept flat in both the extended state and the retracted state, so as to reduce the influence of the movement process of the extension portion 312 on the display effect of the electronic device 20.

In other embodiments, the flexible adhesive connection strip 320 may not be provided, and instead, the first support sheet 330 may be directly provided on the non-display surface of the extension portion 312. The first support sheet 330 may be directly adhered to the non-display surface of the extension 312 using an adhesive such as 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 switch the first supporting sheet 330 between a first state in which the first supporting sheet 330 is straight to support the expansion portion 312 in the straight state and a second state; in the second state, the first support piece 330 is bent to support the expansion portion 312 in the bent state. It can be understood that the first supporting piece 330 is an elastic structure capable of being deformed, and can switch between the first state and the second state according to the state of the expansion portion 312, so that the first supporting piece 330 can support the expansion portion 312 in the bent state and also can support the expansion portion 312 in the flat state.

When the first supporting sheet 330 is in the first state, a portion of the first supporting sheet 330 is not in contact with the expanding portion 312, for example, a middle of the first supporting sheet 330 may have a concave structure, two sides of the first supporting sheet 330 are in contact with the expanding portion 312, and a gap is formed between the middle of the first supporting sheet 330 and the expanding 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 contact with the non-display surface of the extension portion 312. When the first supporting piece 330 is in the second state, the first supporting piece 330 receives the acting force along the radial direction of the shaft 200, so that the first supporting piece 330 is deformed, and a part of the original first supporting piece 330 which is not contacted with the expansion part 312 is attached to the display surface of the expansion part 312, and the appearance of the first supporting piece 330 is consistent with the appearance of the expansion part 312, so that the flexible screen assembly 300 can be repeatedly unfolded and recovered according to the preset movement track.

When the expansion portion 312 is located within the housing 100, a portion of the first support piece 330 abuts the shaft 200. Such as a portion of the first support sheet 330 abutting a surface of the shaft 200, a portion of the first support sheet 330 is not in contact with the shaft 200 (it is understood that a portion of the first support sheet 330 is not next to the shaft 200).

When the expansion portion 312 is located outside the housing 100, a portion of the first support piece 330 abuts the shaft 200. Such as a portion of the first support sheet 330 abutting a surface of the shaft 200, a portion of the first support sheet 330 is not in contact with the shaft 200 (it is understood that a portion of the first support sheet 330 is not next to 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 is wrapped around the surface of the shaft 200.

The size of the first support sheet 330 in the movement 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 movement 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 non-display surface of the entire extension portion 312 and thus support the entire extension portion 312. Compared with the prior art, the flexible display module is directly used as a stretching main body, and the first supporting sheet 330 is arranged on the expansion part 312, so that the expansion part 312 can be in direct contact with the shaft 200 at intervals, and further abrasion to the expansion part 312 in the process of mutual friction between the non-display surface of the expansion part 312 and the outer surface of the shaft 200 is avoided. When the size of the first supporting sheet 330 is larger than the size of the extension portion 312, the projection of the first supporting sheet 330 on the flexible screen assembly 300 is partially located on the extension portion 312, and partially located outside the extension portion 312, for example, 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 piece 330 is located at the main body portion, the side outer surface of the first support piece 330 is flush with the side outer surface of the main body portion 311. For example, the first supporting sheet 330 and the main body portion 311 are both in a rectangular parallelepiped structure, the first supporting sheet 330 may have four side portions connected to each other, and the first supporting sheet 330 has two opposite surfaces connected to two sides of the four side portions to enclose the rectangular parallelepiped structure. Similarly, the main body 311 may also have four interconnected sides and opposite display and non-display surfaces, wherein the first support sheet 330 is disposed on the non-display surface of the main body 311, the four outer side surfaces of the first support sheet 330 are flush with the four outer side surfaces of the main body 311, and the first support sheet 330 may support the main body 311, so that the display surface of the main body 311 is smoother, and the first support sheet 330 is not visible from the outside, thereby maintaining the simplicity of the appearance of the flexible screen assembly 300.

It should be noted that, the first supporting piece 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 piece and the second supporting piece provided in the embodiment of the present application, and the supporting piece may further include a second supporting piece 340, where the second supporting piece 340 is located on a non-display surface of the main body portion 311. The second supporting piece 340 has a different structure from that of the first supporting piece 330, for example, the second supporting piece 340 has a flat structure, which does not have an arc structure, and the second supporting piece 340 can provide a flat bearing surface for the main body portion 311. It should be noted that the second supporting plate 340 may have the same structure as the first supporting plate 330, and may be easy to process.

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 flattened from bending to bending according to the bending shape, and from bending to flattening, it is obvious that the material capable of realizing the two state transition is generally a flexible material, and the material is required to be in a stretching state, such as each layer of film material in the display screen module, but if only the flexible material is in the stretching and bending part, one end of the flexible material cannot be pulled according to the preset bending track in the stretching state. And the display screen module cannot be directly stressed in a stretched state, because the display screen module is easily damaged. Obviously, to realize that the display screen module stretches out and draws back according to the established track at the bending position and ensure that the display screen body is not stressed independently, an attached rigid structure is required to be added in a bending area, but if a common rigid structure is adopted, flattening and bending repeated switching cannot be realized. In the embodiment of the 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 the flexible screen can be easily switched between the unfolding state and the recovery state.

It should be noted that, the structure of the first supporting piece 330 is not limited to this, for example, the first supporting piece 330 may deform in the width direction of the electronic device 20, so that the first supporting piece 330 may be stretched during the movement of the outer surface of the shaft 200, so as to ensure that the first supporting piece 330 can easily support the expansion portion 312 in the telescopic bending region and can realize telescopic bending during the movement along the outer surface of the shaft 200 without risk of damage. It will be appreciated that if a rigid sheet is provided directly on the non-display surface of the extension 312, the rigid sheet may be broken by insufficient tension when moved to the position of the shaft 200. However, if the rubber member or the spring-type elastic member is directly used, the supporting force of the expansion portion 312 may be insufficient due to the excessive elasticity, and thus the flexible screen assembly 300 may be wrinkled or recessed.

For example, as shown in fig. 13, fig. 13 is a schematic view of a second partial structure of a first support sheet and a second support sheet according to an embodiment of the present application. All or a portion of the first support sheet 330 is provided with a plurality of mesh openings such as mesh openings 334 to enhance the deformability of the first support sheet 330, for example, an acidic etching solution may be used to etch the first support sheet 330 to etch a plurality of diamond-shaped mesh openings 334 on the first support sheet 330, such that the first support sheet 330 is in a diamond-shaped wire mesh structure, which may enable the first support sheet 330 to have a stretchability in the width and/or length directions of the electronic device 20. When the first supporting piece 330 moves in the width direction of the electronic device 20, the first supporting piece 330 receives the extrusion force applied by the shaft 200 and the tensile force along the width direction of the electronic device 20, and can be deformed under the action of the extrusion force and the tensile force, and compared with the rigid piece, the first supporting piece 330 in the embodiment of the application can ensure that the first supporting piece 330 cannot be broken due to overlarge tension in the moving process.

Mesh 334 may be regular in shape, such as diamond shaped, rectangular shaped, etc., and mesh 334 may be irregular in shape. For example, in the embodiment of the present application, the mesh 334 has a diamond structure, and the first supporting sheet forms all or a part of the first supporting sheet 330 into a diamond wire mesh structure, and the first supporting sheet 330 having the diamond wire mesh structure has advantages of very good flexibility, and very great advantage in ensuring the flatness of the flexible screen assembly 300, and long bending life.

Wherein, when the size of the first support sheet 330 is equal to the size of the expansion portion 312, the first support sheet 330 may be processed into a diamond wire mesh structure; when the size of the first supporting sheet 330 is larger than that of the extension portion 312, the portion of the first supporting sheet 330 located on the non-display surface of the extension portion 312 may be processed into a diamond-shaped wire mesh structure, and other portions of the first supporting sheet 330 are flat and rigid sheet structures, and etching with an etching solution is not required, for example, the portion of the first supporting sheet 330 located on the non-display surface of the main body portion 311. It will be appreciated that the first support sheet 330 may comprise a first section disposed on the non-display side of the body portion 311, the first section being of a finished rigid sheet structure with no mesh design on the surface, and a second section disposed on the non-display side of the extension portion 312, the second section being provided with a plurality of mesh openings 320, the mesh openings 320 being of a diamond-shaped configuration 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 portion 312 during the movement of the first supporting sheet 330, only a part of the first supporting sheet 330 is processed into a diamond wire mesh structure, so that 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 is ensured, and in addition, the manufacturing difficulty and cost are reduced.

Fig. 14 is a schematic view of a second structure of the flexible screen assembly according to the embodiment of the present application, as 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 protective layer 400 may also be a film layer 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 sandwiched between two protective layers 400, and the protective layers 400 are covered on the mesh holes 334 to block the mesh holes 334 so that an object (an adhesive such as double-sided tape, glue, etc.) provided on the first support sheet 330 does not penetrate into other members through the mesh holes 334. For example, the first support sheet 330 may include a first side and a second side disposed opposite to each other, the first side being a side closer to the non-display side of the flexible screen assembly 300, and the second side being a side farther from the flexible screen assembly 300. Wherein the first side is provided with a first protective layer 410, the first protective layer 410 being provided over the mesh openings 334 to close off the mesh openings 334 from the first side towards the second side; the second side is provided with a second protective layer 420, and the second protective layer 420 is placed over the mesh holes 334 to block the mesh holes 334 in a direction from the second side toward the first side, so that objects (such as double-sided tape, glue, etc. adhesive) placed on the first support sheet 330 (including the first side and the second side) do not penetrate into the flexible screen assembly 300, or the middle frame, or the sliding member through the mesh holes 334.

By arranging the stretchable first supporting sheet 330, the tensile strength can be increased, the damage risk of the flexible screen assembly 300 can be reduced, and the service life of the flexible screen assembly 300 can be prolonged.

Fig. 15 is a schematic structural view of a first sliding member and a second sliding member according to an embodiment of the present application, as 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 flexible adhesive connection strip 320 and located on the main body portion 311, and the second slider 520 may be disposed on the flexible adhesive connection strip 320 and located on the extension portion 312. The first slider 510 and the second slider 520 are slidably connected with the flexible glue connection belt 320, and the first slider 510 and the second slider 520 are disposed at intervals from the shaft 200, and the first slider 510 and the second slider 520 can slide along the surface of the flexible glue connection belt 320 relative to the flexible glue connection belt 320, so that the expansion portion 312 is unfolded outside the housing 100 or stored inside the housing 100 according to the preset movement track.

In the initial state, the first slider 510 is located at a first position (as shown in fig. 4), and the second slider 520 is located at a second position (as shown in fig. 4) of the flexible adhesive tape 320. When the expansion portion 312 moves in the direction outside the housing 100, the first slider 510 and the second slider 520 each move in the direction approaching the shaft 200 such 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) such that the expansion portion 312 located outside the housing 100 can be slidably expanded along the surface of the first slider 510 and the expansion 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 the inside of the housing 100.

It will be appreciated that the first slider 510 may limit movement of the expansion portion 312 gradually wound around the outer surface of the exiting shaft 200 (or around the outer surface of the entering shaft 200), and the second slider 520 may limit movement of the expansion portion 312 gradually wound around the outer surface of the entering shaft 200 (or around the outer surface of the exiting shaft 200), thereby limiting the movement track of the entire expansion portion 312, such that the expansion portion 312 is gradually expanded out of the housing 100 according to the first predetermined movement track (or gradually retracted into the housing 100 according to the second predetermined movement track).

As shown in fig. 16, fig. 16 is a schematic cross-sectional structure of the shaft and flexible screen assembly shown in fig. 2 along the direction P2-P2, where the first slider 510 and the second slider 520 are each provided with a sliding portion, such as a sliding portion 530, and the size and shape of the sliding portion 530 are adapted to the size and shape of the second limiting structure on the flexible glue connection strip 320. For example, when the second limiting structure is a groove structure, the sliding portion 530 may be a protrusion structure; when the second limiting structure is a protruding structure, the sliding portion 530 may be a groove structure.

The flexible glue connection strip 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 flexible glue connection belt 320 is provided with a first limiting portion and a second limiting portion, the first limiting portion is located between the first slider 510 and the shaft 200, and the first limiting portion is used for limiting the sliding distance of the first slider 510 so as to prevent the first slider 510 from excessively sliding and abutting against the shaft 200; the second limiting portion is located between the second slider 520 and the shaft 200, and is used for limiting the sliding distance of the second slider 520 so as to prevent the second slider 520 from excessively sliding against the shaft 200. The limiting part can be a block or a limiting screw or other parts which can be used as a limiting barrier.

In some embodiments, the flexible glue connection strip 320 may be provided with a plurality of telescopic stoppers, and the plurality of telescopic stoppers are disposed at different positions of the flexible glue connection strip 320 at intervals, and the electronic device 20 may control the telescopic stoppers to extend out of the surface of the flexible glue connection strip 320 or retract into the flexible glue connection strip 320. The user may select the expansion size of the expansion portion 312, for example, select to expand 20%, expand 50% or expand 100%, etc., and the electronic device 20 controls the corresponding expansion stop to extend out of the surface of the flexible glue connecting band 320 according to the expansion size selected by the user, so as to stop the flexible glue connecting band 320 from moving continuously, and further control the expansion size of the expansion portion 312. Compared with the roll type flexible screen in the related art, the embodiment of the application can freely select the expansion size of the display screen according to the self requirement by a user, and is more intelligent and humanized.

It should be noted that the structure of the first slider 510 is not limited to this, for example, when the size of the flexible adhesive tape 320 is equal to the size of the extension portion 312, the main portion 311 is not provided with the flexible adhesive tape. 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 steel or metal. The outer surface of the sliding rail structure is flush with the outer surface of the flexible glue connecting band 320, and the sliding rail structure is provided with a protrusion or a groove which is the same as the structure of the second limiting structure, so that the sliding structure can slide from the sliding rail structure to the flexible glue connecting band 320.

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

As shown in fig. 17 and 18, fig. 17 is a schematic structural view of the shaft, the driving motor and the center shaft of the flexible screen assembly shown in fig. 2, and fig. 18 is a schematic structural view of the shaft, the driving motor and the center shaft of the flexible screen assembly shown in fig. 2 and the driving motor. The electronic device 20 may further include a driving motor 600, where the driving motor 600 is connected to the shaft 200, and the driving motor 600 may drive the shaft 200 to rotate, thereby driving the flexible adhesive connection tape 320 to move in a direction outside the housing 100 or inside the housing 100. For example, the shaft 200 is provided with a through hole 220, a plurality of clamping grooves 221 are formed in the hole wall of the through hole 220, the 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 to enable the driving motor 600 to be connected with the shaft 200, and the driving shaft rotates under the driving of the driving motor 600, so that the driving shaft 200 rotates around the driving motor 600. It can be appreciated that the driving motor 600 and the shaft 200 may together form a pulley-type motor device, and the shaft 200 rotates around the driving motor 600, so that the embodiment of the application can save the occupied space of the driving motor 600 on the electronic device 20 compared with the case that the driving motor 600 is disposed outside the shaft 200. Of course, it is also possible to provide the driving motor 600 outside the shaft 200 and provide a fixing member inside the shaft 200, around which the driving motor 600 drives the shaft 200 to rotate.

When the driving motor 600 drives the shaft 200 to rotate clockwise, the flexible glue connection band 320 is driven by the shaft 200 to move around the outer surface of the shaft 200 in the direction of the outside of the housing 100, so that the expansion portion 312 is gradually expanded out of the housing 100; when the driving motor 600 drives the shaft 200 to rotate counterclockwise, the flexible adhesive connection tape 320 is driven by the shaft 200 to move around the outer surface of the shaft 200 toward the inside of the housing 100, so that the expansion portion 312 is gradually recovered inside the housing 100. The electronic device 20 can control the rotation time of the shaft 200 by controlling the working time of the driving motor 600, so as to control the movement distance of the extension portion 312, so that the size of the extension portion 312 which is unfolded outside the housing 100 can be adjusted, the playability is higher, and the user experience is improved.

Fig. 19 is a schematic view of a third structure of the electronic device according to the embodiment of the present application, and fig. 20 is a schematic view of a driving device in the electronic device shown in fig. 19, as shown in fig. 19. The electronic device 20 may further include a driving device 700, and the driving device 700 is used for driving the shaft 200 to reciprocate in the direction of the housing 100, so as to achieve engagement and disengagement between the shaft 200 and the housing 100. The driving device 700 may include a first motor 710 and a pushing mechanism 720, the pushing mechanism 720 being connected to the first motor 710, the first motor 710 for driving the pushing mechanism 720 to push the shaft 200 to reciprocate in a direction parallel to the housing 100, so that the shaft 200 extends out of or enters the housing 100, and separation or engagement between the shaft 200 and the housing 100 is achieved.

Wherein the pushing mechanism 720 may comprise a transmission assembly such as a transmission assembly 721 and a pushing assembly such as a pushing assembly 722, the transmission assembly 721 being connected to the first motor 710, one end of the pushing assembly 722 being connected to the transmission assembly 721, the other end of the pushing assembly 722 being connected to the shaft 200. The first motor 710 is configured to drive the transmission assembly 721 such that the push assembly 722 coupled thereto follows the movement of the transmission assembly 721, thereby moving the push assembly 722 in a direction parallel to the housing 100. The transmission component 721 may be one or a combination of several of a screw transmission component, a gear set or a telescopic component, wherein the telescopic component may include an electric push rod, an electro-hydraulic push rod, a pneumatic push rod or a hydraulic push rod.

The pushing assembly 722 may include a first base such as the first base 7221 and a push rod such as the push rod 7222. The first base 7221 is fixed on the inner surface of the housing 100, a sliding groove is disposed on the first base 7221, 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 pushrod 7222 is coupled to the transmission assembly 721 and the other end of the pushrod 7222 is coupled to the shaft 200.

When the electronic device 20 is to control the housing 100 and the shaft 200 to perform relative movement, the first motor 710 may be controlled to drive the transmission assembly 721 to move, and when the transmission assembly 721 moves, the push rod 7222 is driven to slide in the sliding groove along the direction parallel to the housing 100 in the push rod 7222, so as to drive the shaft 200 to move along the direction parallel to the housing 100, so as to achieve the fitting and separation of the housing 100 and the shaft 200.

For example, the electronic device 20 may control the output shaft of the first motor 710 to rotate in a forward (or reverse) direction, such that the transmission assembly 721 coupled to the output shaft of the first motor 710 follows the motion of the output shaft of the first motor 710, and the motion of the transmission assembly 721 will drive the push rod 7222 to move in a direction away from the housing 100, and the shaft 200 coupled to the push rod 7222 will follow the motion of the push rod 7222, such that the shaft 200 also moves in a direction away from the housing 100, and further such that the shaft 200 extends out of the housing 100, thereby separating the shaft 200 from the housing 100. For another example: the electronic device 20 may control the output shaft of the first motor 710 to rotate in a reverse (or forward) direction, 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 will drive the push rod 7222 to move towards the direction approaching the housing 100 during the movement process, the shaft 200 connected to the push rod 7222 will move along with the movement of the push rod 7222, so that the shaft 200 also moves towards the direction approaching the housing 100, and further the shaft 200 is retracted into the housing 100 from the outside of the housing 100, so as to implement the engagement between the shaft 200 and the housing 100.

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

With continued reference to fig. 20, the drive assembly 721 may include a second base 7211, a drive screw 7212 and a connector 7213, wherein the second base 7211 is fixed to the housing 100. The drive screw 7212 is rotatably coupled to the second base 7211, for example, the drive screw 7212 may be coupled to a bearing embedded in the second base 7211, thereby enabling the drive screw 7212 to rotate relative to the second base 7211. The drive screw 7212 is further coupled to a first motor 710, the first motor 710 being configured to drive the drive screw 7212 for rotation relative to the second base 7211. The connecting piece 7213 is sleeved on the driving screw 7212, the connecting piece 7213 is in transmission connection with the driving screw 7212, the connecting piece 7213 is further connected with the push rod 7222, the connecting piece 7213 is driven by the driving screw 7212 to reciprocate along the axial direction perpendicular to the driving screw 7212, and then the push rod 7222 is driven to reciprocate along the direction parallel to the shell 100, and when the push rod 7222 reciprocates, the shaft 200 follows the push rod 7222 to reciprocate.

Referring to fig. 21, fig. 21 is a schematic structural view of a connecting member in the driving device shown in fig. 20. The driving assembly 721 may further include a guide bar such as guide bar 7214, the guide bar 7214 being disposed on the second base 7211, for example, both ends of the guide bar 7214 may be directly inserted into the coupling holes of the second base 7211. The guide rod 7214 and the driving screw 7212 are arranged in parallel, the connecting piece 7213 can be sleeved on the driving screw 7212 and the guide rod 7214 at the same time, and the guide rod 7214 can play a role in guiding and positioning the connecting piece 7213. For example, the connection member 7213 may be provided with a first through hole 7213a, a second through hole 7213b and a third through hole 7213c, the connection member 7213 being sleeved on the driving screw 7212 through the first through hole 7213a, sleeved on the push rod 7222 through the second through hole 7213b, and sleeved on the guide rod 7214 through the third through hole 7213c and in sliding contact with the guide rod. The wall of the first through hole 7213a is provided with a driving thread which is meshed with the screw tooth of the driving screw 7212, so that the driving screw 7212 drives the connecting piece 7213 to do linear motion along the direction parallel to the shell 100 through the first through hole 7213a when rotating. It will be appreciated that rotation of the drive screw 7212 can be translated into linear movement of the connecting member 7213.

As shown in fig. 22 and 23, fig. 22 is a schematic diagram of a fourth structure of the electronic device provided in the embodiment of the present application, and fig. 23 is a schematic diagram of a driving device in the electronic device shown in fig. 22. The transmission assembly 721 may also be a gear set transmission, for example, the transmission assembly 721 may include a gear, such as gear 7215, the gear 7215 being disposed on an output shaft of the first motor 710, and the first motor 710 may drive the gear 7215 for rotation. The push rod 7222 is in driving connection with the gear 7215, for example, a plurality of teeth may be disposed on an outer surface of the push rod 7222, and the push rod 7222 is meshed with the gear 7215 through the teeth, so that the gear 7215 can drive the push rod 7222 to reciprocate along a direction parallel to the housing 100 when rotating. It should be noted that the transmission assembly 721 may also include a plurality of gears, and the reciprocating motion of the push rod 7222 is driven by the mutual transmission of the plurality of gears.

Fig. 24 is a schematic view of a fifth structure of the electronic device according to the embodiment of the present application, as shown in fig. 3, fig. 22, and fig. 24. The electronic device 20 may further include a second motor 800, the second motor 800 being connected to the flexible adhesive connection tape 320, the second motor 800 being operable to drive the flexible adhesive connection tape 320 to move in response to the relative movement of the housing 100 and the shaft 200, to retract a portion of the flexible screen assembly 300 within the housing 100 or to extend a portion of the flexible screen assembly 300 outside the housing 100, 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 housing 100, the second motor 800 may drive the flexible adhesive connection tape 320 to move along the shaft 200 after a preset interval time, so that the expansion portion 312 originally stored in the housing 100 slides along the outer surface of the shaft 200 and is gradually unfolded outside the housing 100 (or outside the electronic device 20) such as shown in fig. 3, further, the expansion portion 312 is unfolded outside the electronic device 20, the main portion 311 and the expansion portion 312 may jointly display one screen, or may respectively display two screens, and compared with the case where only the main portion 311 is used for displaying in an initial state, the display area of the electronic device 20 may be increased by unfolding the expansion portion 312 outside the housing 100.

In the embodiment of the application, the two driving devices are provided to control the motion states of the housing 100, the shaft 200 and the flexible glue connection belt 320 respectively, so that the display area of the flexible screen assembly 300 is selectable. The embodiments of the present application may increase the display area of the electronic device 20 without additional installation space for the flexible screen assembly 300 (or display screen) relative to a display screen having a fixed installation space in the related art.

With continued reference to fig. 22 and 24, the second motor 800 is used to drive the flexible adhesive tape 320 to curl or stretch so that the expansion portion 312 is received in the housing 100 or is unfolded outside the housing 100. For example, one end of the flexible glue connecting band 320 is wound on the output shaft of the second motor 800, and the other end of the flexible glue connecting band 320 is connected with the casing 100, so that the stretching object can be transferred onto the flexible glue connecting band 320, and the damage degree of the flexible screen assembly 300 in the stretching process can be reduced relative to the case that the flexible screen assembly 300 is directly connected with the second motor 800 and the casing 100.

When the electronic device 20 is to control the flexible screen assembly 300 to be unfolded outside the housing 100, the electronic device 20 can control the second motor 800 to drive the flexible adhesive connection tape 320 from the curled state to the stretched state gradually, so that the expanding portion 312 can slide along the outer surface of the shaft 200 in a direction away from the second motor 800, so as to gradually unfold the expanding portion 312 originally stored inside the housing 100 outside the electronic device 20 (or the housing 100) and display a screen together with the main portion 311 originally exposed outside the electronic device 20.

When the electronic device 20 is to control the flexible screen assembly 300 to be accommodated in the housing 100, the electronic device 20 can control the second motor 800 to drive the flexible adhesive connection tape 320 from the stretched state to the curled state gradually, so that the flexible screen assembly 300 can slide along the outer surface of the shaft 200 gradually towards the direction approaching to the second motor 800, so as to gradually recover the expansion portion 312 originally stretched out on the exterior of the electronic device 20 (or the housing 100) into the housing 100.

The size of the extension portion 312 is smaller than or equal to the size of the housing 100, so that the extension portion 312 can be completely unfolded when being stored in the housing 100, and no curling is needed.

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 is loosened, and thus, bad phenomena such as wrinkles or unevenness may occur in the flexible screen assembly 300, and further, the image display effect of the electronic device 20 is affected.

As shown in fig. 25, fig. 25 is a schematic view of a sixth structure of an electronic device according to an embodiment of the present application. In order to make the flexible screen assembly 300 always in a tightening state and ensure the tension of the flexible screen assembly 300, the processor of the electronic device 20 in this embodiment of the present application, such as the processor 900, is electrically connected with the driving device 700 and the second motor 800, the processor 900 may be used to drive the driving device 700 to drive the housing 100 and the shaft 200 to move relatively at different moments, and the second motor 800 to drive the flexible glue connection belt 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 step by step and different moments. 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 short, which is mainly used for ensuring that the two ends of the flexible screen assembly 300 are always in a stressed and tensed state, ensuring the tension of the flexible screen assembly 300, ensuring that adverse phenomena such as wrinkles and unevenness do not occur, and further ensuring 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 deployment of the extension 312 is desired, the processor 900 may control the drive device 700 to move the drive shaft 200 in a direction away from the housing 100 at a first time T1 such that the shaft 200 slowly extends out of the housing 100 to effect separation of the housing 100 and the shaft 200. At the second time T2 when the shaft 200 moves, the processor 900 controls the second motor 800 to drive the flexible adhesive connection tape 320 to be slowly spread so that the expansion portion 312 of the flexible screen assembly 300 can be slid 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=t1+t1, where T1 is a first preset interval time, and the first preset interval time may be set according to an actual situation, which is not limited in the embodiment of the present application. It will be appreciated that when the extension 312 is deployed, the shaft 200 moves earlier than the flexible adhesive strip 320, so that the flexible adhesive strip 320 is always in a straightened state, and thus the flexible screen assembly 300 is always in a straightened state during the gradual deployment of the extension 312 outside the housing 100.

When the extension portion 312 needs to be recovered into the housing 100, the processor 900 may control the second motor 800 to drive a portion of the flexible glue joint 320 to curl slowly at the third time T3, and the flexible glue joint 320 drives the extension portion 312 to move in a direction approaching the second motor 800 during the curling process. At the time of movement of the flexible screen assembly 300 to the fourth time T4, the processor 900 controls the driving device 700 to move the driving shaft 200 in a direction away from the housing 100 such that the shaft 200 is slowly retracted into the housing 100 to achieve the fitting of the housing 100 and the shaft 200. The third time T3 is earlier than the fourth time T4, for example, t4=t3+t2, and T2 is a second preset interval time, which may be set according to an actual situation, which is not limited in the embodiment of the present application. It will be appreciated that when the extension 312 is retracted, the flexible adhesive linkage 320 moves earlier than the shaft 200, such that the flexible adhesive linkage 320 is always in a straightened state, and such that the flexible screen assembly 300 is always in a straightened state during the gradual retraction of the extension 312 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 flexible adhesive connection tape 320. For example, a tension detector may be provided on the flexible adhesive connection tape 320, and the tension detector is used to detect a tension value of the flexible adhesive connection tape 320. When the expansion portion 312 needs to be expanded, the processor 900 firstly controls the driving device 700 to start, acquires the first tension value of the flexible glue connecting band 320 detected by the tension detector, and controls the second motor 800 to start when the first tension value of the flexible glue connecting band 320 is larger than the first preset tension value. Similarly, when the extension portion 312 needs to be recovered, the processor 900 first controls the second motor 800 to start, and obtains the second tension value of the flexible glue connection belt 320 detected by the tension detector, and controls the driving device to start when the second tension value of the flexible glue connection belt 320 is greater than the second preset tension value. According to the embodiment of the present application, 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 flexible adhesive connecting belt 320, so that the situation that the flexible screen assembly 300 is wrinkled due to too small tension value of the flexible adhesive connecting belt 320 caused by too small starting time interval of the driving device 700 and the second motor can be avoided, and the situation that the flexible adhesive connecting belt 320 is damaged due to too large tension value caused by too large starting time interval of the driving device and the second motor can be avoided. Compared with the starting control of the two driving devices according to the fixed time interval, the control of the embodiment of the application is more accurate and intelligent.

In the above-described embodiment, alternatively, the electronic apparatus 20 may be provided with only the driving device 700 without providing the second motor 800, such as shown in fig. 26, and fig. 26 is a seventh structural schematic diagram of the electronic apparatus provided in the embodiment of the present application. One end of the flexible glue connection belt 320 is connected with the casing 100, the other end of the flexible glue connection belt 320 is connected with the driving device 700, the driving device 700 drives the casing 100 and the shaft 200 to move relatively and drives the flexible glue connection belt 320 to move, so that the extension part 312 extends out of the casing 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 view of a driving device in the electronic apparatus shown in fig. 26, and fig. 28 is a schematic structural view of a pushing assembly in the driving device shown in fig. 26. The push rod 7222 comprises a supporting portion 7222a, a rotating shaft 7222b and a pushing portion 7222c, one end of the pushing portion 7222c is fixed on the supporting portion 7222a, the other end of the pushing portion 7222c is connected with the shaft 200, the rotating shaft 7222b is arranged at one end, away from the shaft 200, of the supporting portion 7222a, and the rotating shaft 7222b is in transmission connection with the flexible glue connecting belt 320. For example, the flexible glue connection belt 320 is sleeved on the rotating shaft 7222b and fixedly connected with the housing 100 at two ends of the flexible glue connection belt 320.

When the expansion portion 312 needs to be unfolded, the processor 900 may control the first motor 710 to drive the transmission assembly 721, the transmission assembly 721 drives the pushing assembly 722 to move in a direction away from the housing 100, the pushing assembly 722 pushes the shaft 200 to also move in a direction away from the housing 100 through the pushing portion 7222c during the movement, and meanwhile, since the rotating shaft 7222b also moves in a direction away from the housing 100, the flexible glue connection strip 320 also moves along the rotating shaft 7222b in a direction away from the housing 100 and slides along the outer surface of the rotating shaft 7222b, so as to increase the extension length of the flexible glue connection strip 320, and the expansion portion 312 slides out of the housing 100 under the driving of the flexible glue connection strip 320, so that the expansion portion 312 is exposed outside the electronic device 20.

When the expansion portion 312 needs to be recovered, the processor 900 may control the first motor 710 to drive the transmission assembly 721, the transmission assembly 721 drives the pushing assembly 722 to move towards the direction approaching the housing 100, the pushing assembly 722 pulls the shaft 200 to move towards the direction approaching the housing 100 through the pushing portion 7222c during the movement, and meanwhile, the flexible glue connection belt 320 also slides along the outer surface of the rotation shaft 7222b along the direction approaching the housing 100 along with the rotation shaft 7222b due to the rotation shaft 7222b moving towards the direction approaching the housing 100, so as to reduce the extension length of the flexible glue connection belt 320, and the expansion portion 312 slides into the housing 100 under the driving of the flexible glue connection belt 320, so that the expansion portion 312 is recovered inside the housing 100.

It should be noted that, in the process of expanding the expansion portion 312 of the flexible screen assembly 300 out of the housing 100 or recovering the flexible screen assembly 300 into the housing 100, the flexible screen assembly 300 is kept in a straightened state under the combined action of the shaft 200 and the flexible adhesive connection belt 320, so as to ensure that the display effect of the image of the electronic device 20 is not affected.

In order to avoid overlarge friction force between the flexible glue connecting band 320 and the rotating shaft 7222b, the rotating shaft 7222b in the embodiment of the application is rotatable, such as the rotating shaft 7222b is sleeved outside the fixed shaft 7222d and is rotatably connected with the fixed shaft 7222d, so that the rotating shaft 7222b can rotate around the fixed shaft 7222d, and the rotating shaft 7222b can be driven to rotate when the flexible glue connecting band 320 moves, friction force between the flexible glue connecting band 320 and the rotating shaft 7222b can be reduced, and the flexible glue connecting band 320 moves more smoothly. The shaft 7222b may also form a rolling mechanism in combination with the shaft 200, thereby ensuring smooth recovery and easy deployment of the flexible screen assembly 300.

It can be appreciated that the first motor 710 in the embodiment of the present application 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 movement distance of the pushing portion 7222c, the unfolding length of the expanding portion 312 and the movement distance of the flexible adhesive connecting belt 320 are equal, and further, the flexible screen assembly 300 is ensured to be in a state of being tightly stretched at all times (ensuring that the tension of the flexible screen assembly 300 is within a certain range) during the unfolding process and the recovery process, so that abnormal situations such as overlarge damage to the tension of the flexible screen assembly 300 or too small wrinkles of the flexible screen assembly 300 caused by the out-of-synchronization of the unfolding are avoided.

The relative movement of the housing 100 and the shaft 200 and the deployment and recovery of the flexible screen assembly 300 can be realized by the driving device 700, which can reduce one driving device compared with the above-mentioned embodiments, and can simplify the structure of the electronic device 20 based on the above-mentioned embodiments.
