Referring to FIG. 3 , FIG. 3 is a second schematic structural diagram of the electronic device provided by the embodiment of the present application. The electronic device 20 may also include a flexible screen assembly such as a 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 the narrow screen mode, the flexible screen assembly 300 The display area is fixed; in the widescreen mode, the display area of the flexible screen assembly 300 can be expanded. For example, the flexible screen assembly 300 may include a flexible display module 310 and a deformable support member, and the support member is located on the non-display surface side of the flexible display module 310 for supporting the flexible display module 310 . It can be understood that the structural strength of the supporting member is relatively high. On the one hand, it can support the flexible display module 310 and improve the flatness of the flexible display module, so that the flexible display module 310 is not easy to collapse or wrinkle during the display process. The supporting member can also improve the overall strength of the flexible screen assembly 300 and can protect the flexible screen assembly 300 from damage during stretching. Wherein, the flexible display module 310 may be an OLED (Organic Light Emitting Diode) module, and the OLED module may include a display substrate and a packaging material, and an organic luminescent substance is encapsulated between the display substrate and the packaging material, and the OLED module It includes several OLED units, and each OLED unit is electrically connected to the main board of the electronic device to realize self-illumination and display images. The flexible display module 310 can also be an LCD (Liquid Crystal Display) module. The LCD module can include a display substrate and a packaging material.

Provide voltage to change the alignment direction of liquid crystal molecules, and the light projected by the backlight will work together inside the LCD module to form an image in the display area to display the picture.

The flexible display module 310 may include a main part 311 and an extension part 312. The main part 311 is arranged on the casing 100, and the extension part 312 can move relative to the casing 100, so that the extension part 312 can be deployed outside the casing 100 or recovered in the Inside the housing 100. During the movement, the extension part 312 can be deformed to switch between the bent state and the straight state. The stopper is located at the bent position of the extension part 312 and is against the support member, so that the stopper and the support part can support the extension part together. 312 bend position.

Please continue to refer to FIG. 2, the support member can also include a soft rubber connection belt such as a soft rubber connection belt 320320, the hardness (Shore A) of the soft rubber connection belt 320 is (60-75) degrees, such as 65 degrees , 68 degrees, 70 degrees or 75 degrees, etc. The soft rubber connection belt 320 can adopt rubber, silica gel and TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) and the like. The soft rubber connection strip 320 is arranged on the non-display surface of the extension part 312. The soft rubber connection strip 320 can provide a flat bearing surface for the extension part 312, so that the extension part 312 can be unfolded smoothly without wrinkles or depressions. Moreover, compared with the rigid material, the hardness of the soft rubber connecting belt 320 used in the embodiment of the present application is between 60 degrees and 75 degrees, which can reduce the damage to the extension part 312 during the movement of the soft rubber connecting belt 320, and then protect the extension part. The contact surface of 312 and soft rubber connection belt 320 is not easy to wear. In addition, since the extension part 312 often generates friction with the shaft 200 during movement, the extension part 312 is easily damaged. However, in the embodiment of the present application, by adding a soft rubber connection belt 320 to the extension part 312 that needs to move, the frictional force originally acting on the extension part 312 can be transferred to the soft rubber connection belt 320, and the extension part 312 can be further protected.

The soft rubber connecting band 320 is provided with a second limiting structure such as a second limiting structure, and the second limiting structure is arranged on the side of the soft rubber connecting band 320 away from the expansion part 312, and the second limiting structure can be connected with the first limiting structure. match. For example: when the first position-limiting structure is a protruding structure, the second position-limiting structure can be a groove structure. At this time, the first position-limiting structure can be accommodated in the second position-limiting structure, and can be connected with the second position-limiting structure. The interference fit connection makes the soft rubber connection belt 320 move according to the preset motion trajectory (such as linear motion in a direction parallel to the housing 100) under the limiting action of the first limiting structure and the second limiting structure, and then The extension part 312 is made to move to the outside of the housing 100 or to the inside of the housing 100 according to a preset movement track. Another example: when the first position-limiting structure is a groove structure, the second position-limiting structure can be a protruding structure. At this time, the second position-limiting structure can be accommodated in the first position-limiting structure, and can The groove walls of the structure are connected with an interference fit. Also for example: when the number of the first limiting structure is multiple, a part of the first limiting structure is a protruding structure, and a part of the first limiting structure is a groove structure, correspondingly, it can be arranged on the outer surface of the soft rubber connection belt 320 A plurality of second position-limiting structures, wherein a part of the second position-limiting structures matches with the protruding structure, and a part of the second position-limiting structures matches with the groove structure. It can be understood that the shape and size of the first limiting structure and the second limiting structure match each other and abut against each other to limit the movement path of the soft rubber connection belt 320 .

When the flexible screen assembly 300 is in the narrow screen mode or the wide screen mode, the main part 311 is always fixed on the outer surface of the housing 100 so as to be exposed to the outside of the electronic device 20. At this time, the extension part 312 is in the storage state. Hidden inside the housing 100, it cannot be used to display information, and it is only displayed through the main part 311 of the flexible screen assembly 300; when the flexible screen switches from the narrow screen mode to the wide screen mode, the user can pull the shaft 200 away from the housing 100 (or the driving mechanism can be set to drive the shaft 200 to move), the shaft 200 will drive at least a part of the extension part 312 to gradually rotate out of the housing 100 along the outer surface of the shaft 200 during the movement, and at this time the extension part 312 At least a part is exposed outside the housing 100 to realize switching from the narrow screen mode to the wide screen mode. The exposed extension part 312 can display information together with the main part 311 , and the display area can be increased compared with information display using only the main part 311 . When the flexible screen switches from the wide screen mode to the narrow screen mode, the extension part 312 can be gradually rotated into the inside of the housing 100 along the outer surface of the shaft 200 toward the direction close to the housing 100 (either manually or by The expansion or storage of the flexible screen assembly 300 is realized by mechanical driving), so that at least a part of the extension part 312 is stored only in the casing 100, and the extension part 312 will drive the shaft 200 to move toward the direction of the casing 100 during the movement, thereby shortening the shaft 200. 200 and the housing 100 (or the reciprocating motion of the shaft 200 may also be driven by mechanical driving).

In the embodiment of the present application, by providing a soft rubber connection belt on the extension part, the degree of damage of the flexible screen assembly 300 during movement can be reduced, and the service life of the flexible screen assembly 300 can be prolonged. In addition, the embodiment of the present application also enables the flexible screen assembly 300 to be deployed outside the casing 100 or stored in the casing 100 according to a preset movement track through the mutual cooperation of the first limiting structure and the second limiting structure. In related technologies, the embodiment of the present application can prevent the flexible screen assembly 300 from being shifted during the expansion process, thereby preventing the flexible screen assembly 300 from being pulled in the length direction of the electronic device 20 , and further protecting the flexible screen assembly 300 from damage.

As shown in FIG. 4 , FIG. 4 is a schematic diagram of the first type of side structure of the shaft and flexible screen assembly shown in FIG. 2 . The size of the soft glue connection strip 320 is equal to the size of the extension part 312, and the projection of the soft glue connection strip 320 on the flexible screen assembly 300 is located at the extension part 312, so that the soft glue connection strip 320 can cover the entire non-display surface of the extension part 312, and then The entire extension 312 is protected. Compared with the related art, which directly uses the flexible screen as the stretching body, this application sets the soft rubber connection belt 320 on the extension part 312, which can space the extension part 312 from direct contact with the shaft 200, thereby avoiding the non-display surface of the extension part 312 from directly contacting the shaft 200. The wear on the expansion portion 312 is caused by the friction between the outer surfaces of the shaft 200 against each other.

As shown in FIG. 5 , FIG. 5 is a schematic diagram of a second side structure of the shaft and flexible screen assembly shown in FIG. 2 . The size of the soft glue connection strip 320 can also be larger than the size of the extension part 312 . When the size of the soft glue connection strip 320 is larger than the size of the extension part 312, the projection of the soft glue connection strip 320 on the flexible screen assembly 300 is partly located at the extension part 312 and partly located outside the extension part 312, such as on the main body part 311 , can also be located in the accommodation space of the housing 100, for example, it can be used to connect the driving motor, and the driving motor drives the expansion part by driving the part of the soft rubber connection belt 320 located in the accommodation space of the housing 100 to curl or stretch 312 unfold or recycle.

When a part of the soft glue connecting strip 320 is located on the main body portion 311 , the side outer surface of the soft glue connecting strip 320 is flush with the side outer surface of the main body portion 311 . For example, both the soft rubber connecting strip 320 and the main body 311 have a cuboid structure, the soft rubber connecting strip 320 can have four interconnected side portions, and the soft rubber connecting strip 320 has two opposite surfaces, and the two surfaces are connected on four sides. The two sides of each side are surrounded to form a cuboid structure. Similarly, the main body part 311 can also have four interconnected side parts and opposite display surfaces and non-display surfaces, wherein the soft glue connection strip 320 is arranged on the non-display surface of the main body part 311, and the four soft glue connection strips 320 The side outer surface is flush with the four side outer surfaces of the main body part 311, and the soft rubber connection belt 320 can support the main body part 311, so that the display surface of the main body part 311 is more flat and cannot be observed from the outside. The soft rubber connection strip 320 keeps the appearance of the flexible screen assembly 300 simple.

As shown in FIG. 6 , FIG. 6 is a schematic cross-sectional structure diagram of the shaft and flexible screen assembly shown in FIG. 2 along the direction P1-P1. The first limiting structure includes a first limiting groove 210, the first limiting groove 210 is arranged around the outer surface of the shaft 200, and the groove width of the first limiting groove 210 is from the outer surface of the shaft 200 toward the inner surface of the shaft 200 gradually narrows. The second limiting structure includes a first limiting protrusion 321, the first limiting protrusion 321 is arranged on the outer surface of the soft rubber connection belt 320, and protrudes from the surface of the soft rubber connection belt 320, the soft rubber connection belt 320 The outer surface refers to the side away from the flexible screen assembly 300 , and the inner surface of the soft glue connection strip 320 refers to the side connected to the non-display surface of the flexible screen assembly 300 . Wherein, the material of the first limiting protrusion 321 is the same as that of the soft rubber connecting belt 320, such as rubber, and the width of the first limiting protrusion 321 is from the inner surface of the soft rubber connecting belt 320 toward the soft rubber connecting belt. The direction of the outer surface of 320 gradually widens, so that the shape of the first limiting protrusion 321 can match the shape of the first limiting groove 210, and the first limiting protrusion 321 can be embedded in the first limiting groove 210, Moreover, the first limiting protrusion 321 can limit the moving track of the flexible screen assembly 300 through the first limiting groove 210 , so that the extension part 312 moves into or out of the housing 100 according to a preset track. The first limiting protrusion 321 is connected with the first limiting groove 210 by an interference fit. For example, the size of the first limiting protrusion 321 is slightly larger than the size of the first limiting groove 210, so that the first limiting protrusion 321 is mounted on the first limiting groove 210. When inside the first limiting groove 210, the outer surface of the first limiting protrusion 321 and the groove wall of the first limiting groove 210 are pressed against each other to increase the distance between the first limiting groove 210 and the first limiting protrusion 321. The abutting firmness can also increase the coefficient of friction between the shaft 200 and the soft rubber connecting belt 320 , forming an effective friction zone between the shaft 200 and the soft rubber connecting belt 320 . It can be understood that, if the coefficient of friction between the shaft 200 and the soft rubber connection belt 320 is too small, the soft rubber connection belt 320 may slip during the movement around the shaft 200, thereby causing the extension part 312 to expand. Not smooth with storage. In the embodiment of the present application, the first limiting groove 210 and the first limiting protrusion 321 can make the soft rubber connection belt 320 not easy to slide, thereby ensuring the display reliability of the flexible screen assembly 300 . It should be noted that the shape of the first limiting groove 210 is not limited thereto, for example, the first limiting groove 210 may also be a dovetail groove, a square groove, or the like.

As shown in FIGS. 7 to 10 , FIG. 7 is a schematic diagram of the first structure of the flexible screen assembly provided by the embodiment of the present application, and FIG. 8 is a schematic diagram of the first structure of the first support piece in the flexible screen assembly shown in FIG. 7 . Fig. 9 is a schematic diagram of a partial structure of the first support piece shown in Fig. 8, Fig. 10 is a schematic diagram of a cross-sectional structure of the first support piece shown in Fig. 8 along P3-P3, and Fig. 11 is a schematic diagram of the first support piece shown in Fig. 8 along P4- Schematic diagram of the cross-sectional structure of P4.

The support can also include a first support piece 330, the first support piece 330 is a rigid structure, such as the first support piece 330 can be made of metal material, such as the first support piece 330 can be a steel sheet, an aluminum sheet, a copper sheet, etc. . The first supporting sheet 330 can also be made of rubber material or silicone material. The first support piece 330 is embedded in the soft rubber connection belt 320 , for example, the soft rubber connection belt 320 can be injection-molded on the first support piece 330 so that the first support piece 330 is wrapped around the soft rubber connection belt 320 Inside, the first supporting sheet 330 is not in direct contact with the flexible screen assembly 300 , so as to achieve the purpose of protecting the flexible screen assembly 300 .

The first support piece 330 can be deformed so that the first support piece 330 can be converted between the first state and the second state. In the first state, the first support piece 330 is straight to support the extension of the straight state. 312 ; in the second state, the first supporting piece 330 is bent to support the extended portion 312 in the bent state. It can be understood that the first support piece 330 is a deformable structure, which can switch between the first state and the second state according to the state of the extension part 312, so that the first support piece 330 can be bent The extended part 312 in the flat state supports the extended part 312 in the flat state.

For example, the first support piece 330 may include a first side portion 331, a second side portion 332 and a concave portion 333, the concave portion 333 is located between the first side portion 331 and the second side portion 332, and the first side portion 331 is located on the shaft. At one end of the shaft 200 , the second side portion 332 is located at the other end of the shaft 200 , and the concave portion 333 is located at the middle of the shaft 200 . The concave portion 333 is formed by bending away from the flexible display module 310 . It can be understood that the structure of the first support piece 330 is similar to that of a tape measure, the cross section of the first support piece 330 along the width direction of the electronic device 20 is an arc structure, and the bending direction of the first support piece 330 faces away from Shaft 200. When the soft rubber connection belt 320 moves along the outer surface of the shaft 200 , the first supporting piece 330 can be deformed so that the concave portion 333 can switch between the first bending state and the second bending state.

For example, when the first support piece 330 is in the first state, the concave portion 333 is in the first curved state, and the first curved state refers to a state that bends away from the flexible display module 310 . When the soft rubber connecting belt 320 moves along the shaft 200, the soft rubber connecting belt 320 moving to the position of the shaft 200 will abut against the shaft 200. During this process, the first supporting piece 330 inside the soft rubber connecting belt 320 The soft rubber connection belt 320 can receive the force along the radial direction of the shaft 200 and generate deformation, so that the concave part 333 switches from the first bending state to the second bending state, and the rest of the first supporting piece that is not in contact with the shaft 200 The part remains as it is, that is, it is in the first bent state. Wherein, the second bending state refers to the state where the concave portion 333 bends toward the direction close to the flexible display module 310, so that the bending direction of the first support piece 330 is the same as the radian of the shaft 200, thereby improving the connection between the soft rubber connecting strip 320 and the shaft. The fitting degree of 200 makes the movement of the soft rubber connection belt 320 more stable. When the soft rubber connecting belt 320 gradually moves to the outside of the housing 100 or inside the housing 100 along the outer surface of the shaft 200, the soft rubber connecting belt that was originally in contact with the shaft 200 gradually moves away from the shaft 200. The pressing force of a support piece 330 will be gradually released, and then the concave portion 333 will switch from the second bending state to the first bending state.

It can be understood that, when the first supporting piece 330 is in the first state, the cross-sectional shape of the first supporting piece 330 is shown in FIG. Pushing against its back, it can be deformed and turned into a straight shape, so that the shape of the first support piece 330 is the same as that of the extension part 312 , and then the extension part 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 be deformed when it receives a radial force along the shaft 200, and can be turned from a concave shape to a straight shape, as shown in FIG. 11 ; and The original concave shape is restored after receiving no force along the radial direction of the shaft 200 .

It should be noted that the structure of the first support sheet 330 is not limited thereto. For example, the first support sheet 330 may have a plurality of recesses 333 arranged at intervals, and one recess 333 faces away from the flexible display module. The direction of the group 310 is bent, and when the expansion part moves onto the shaft 200, all or part of the recessed part 333 is deformed when it receives a radial force along the shaft 200, so that the recessed part 333 is removed from the non-display surface of the main part. Bending towards the display surface of the main body, at this time, the plurality of recessed parts 333 switch from the first bending state to the second bending state. When the extension portion 312 is away from the shaft 200 , the concave portion 333 returns to the state of bending away from the flexible display module 310 .

It can be understood that, if the first support piece 330 is an ordinary straight rigid structure, when the first support piece 330 moves to the position of the shaft 200, due to the interaction between the shaft 200 and the first support piece 330 The force will cause the first support piece 330 to deform into a bent state and then make the first support piece 330 adhere to the outer surface of the shaft 200. When the first support piece 330 leaves the position of the shaft 200, the shaft 200 and the first support The interaction force between the sheets 330 disappears, but because the first supporting sheet 330 is a straight rigid structure, it cannot restore the original straight shape without the action of other forces after deformation, for example, it will present the original The bent state will also make the extension portion 312 appear uneven, which will affect the display effect of the electronic device 20 . However, the concave part 333 of the present application can 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) it is switched from the first bending state to the second bending state, and the movement Switch back from the second curved state to the first curved state when going to other positions, which can realize the free switching of the expanded part 312 in the unfolded state and the recovered state, and can make the expanded part 312 remain flat in the expanded state and recovered state, reducing The influence of the movement process of the extension part 312 on the display effect of the electronic device 20 .

In some other embodiments, the soft glue connection strip 320 may not be provided, and instead, the first support piece 330 is directly provided on the non-display surface of the extension part 312 . The first support sheet 330 can be directly bonded to the non-display surface of the extension part 312 by using an adhesive such as double-sided tape or glue.

For example, the first support piece 330 can be directly arranged on the non-display surface side of the flexible display module 310, and the first support piece 330 can be deformed so that the first support piece 330 can be switched between the first state and the second state. In one state, the first support piece 330 is straight to support the extension portion 312 in the straight state; in the second state, the first support piece 330 is curved to support the extension portion 312 in the bent state . It can be understood that the first support piece 330 is a deformable elastic structure, which can switch between the first state and the second state according to the state of the expansion part 312, so that the first support piece 330 can be bent The extended part 312 in the folded state can support the extended part 312 in the straight state.

When the first support piece 330 is in the first state, a part of the first support piece 330 is not in contact with the expansion portion 312, for example, there may be a concave structure in the middle of the first support piece 330, and the two sides of the first support piece 330 are in contact with the expansion portion 312. The part 312 is in contact, and the middle of the first support piece 330 has a gap with the expansion part 312; it can also be that the first support piece 330 has a plurality of concave structures, and the first support piece 330 has a gap between the part with the concave structure and the expansion part 312, Other parts of the first support piece 330 are in contact with the extension part 312 or in other words, contact with the non-display surface of the extension part 312 . When the first support piece 330 is in the second state, because the first support piece 330 receives the radial force along the shaft 200, the first support piece 330 is deformed, and the original first support piece 330 is not expanded. The contact part of the part 312 is attached to the display surface of the extension part 312, so that the shape of the first support piece 330 is consistent with the shape of the extension part 312, so as to ensure that the flexible screen assembly 300 can be repeatedly unfolded and recovered according to the preset movement track.

When the extension part 312 is located in the casing 100 , a part of the first support piece 330 abuts against the shaft 200 . For example, a part of the first support piece 330 is in contact with the surface of the shaft 200 , and a part of the first support piece 330 is not in contact with the shaft 200 (it can be understood that a part of the first support piece 330 is not adjacent to the shaft 200 ).

When the extension part 312 is located outside the housing 100 , a part of the first support piece 330 abuts against the shaft 200 . For example, a part of the first support piece 330 is in contact with the surface of the shaft 200 , and a part of the first support piece 330 is not in contact with the shaft 200 (it can be understood that a part of the first support piece 330 is not adjacent to the shaft 200 ). It can be understood that, at this time, a part of the expansion part 312 is laid flat on the outside of the casing 100 , and a part of the expansion part 312 is sleeved on the surface of the shaft 200 .

The size of the first support piece 330 in the direction of movement of the extension part 312 may be greater than or equal to the size of the extension part 312, when the size of the first support piece 330 in the direction of movement of the extension part 312 is equal to the size of the extension part 312, the second The projection of a support piece 330 on the flexible screen assembly 300 is located at the extension part 312 , so that the first support piece 330 can cover the entire non-display surface of the extension part 312 , thereby supporting the entire extension part 312 . Compared with the related art, which directly uses the flexible display module as the stretching body, the present application sets the first support piece 330 on the extension part 312, which can space the extension part 312 from direct contact with the shaft 200, thereby avoiding the non-display surface of the extension part 312 The wear on the expansion portion 312 during direct friction with the outer surface of the shaft 200 . When the size of the first support piece 330 is larger than the size of the extension part 312, the projection of the first support piece 330 on the flexible screen assembly 300 is partly located at the extension part 312 and partly located outside the extension part 312, such as on the main body part 311 , may also be located in the accommodation space of the housing 100 .

When a part of the first supporting piece 330 is located on the main body portion, the side outer surface of the first supporting piece 330 is flush with the side outer surface of the main body portion 311 . For example, both the first supporting piece 330 and the main body portion 311 have a cuboid structure, the first supporting piece 330 may have four interconnected side portions, and the first supporting piece 330 has two opposite surfaces, and the two surfaces are connected on four sides. The two sides of each side are surrounded to form a cuboid structure. Similarly, the main body part 311 may also have four interconnected side parts and opposite display surfaces and non-display surfaces, wherein the first support piece 330 is arranged on the non-display surface of the main body part 311, and the four first support pieces 330 The side outer surfaces are flush with the four side outer surfaces of the main body part 311, and the first supporting sheet 330 can support the main body part 311, so that the display surface of the main body part 311 is more flat and cannot be observed from the outside. The first supporting sheet 330 maintains 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, such as shown in FIG. 12, which is a schematic diagram of the first partial structure of the first supporting piece and the second supporting piece provided by the embodiment of the present application. , the supporting member may further include a second supporting piece 340 , and the second supporting piece 340 is located on the non-display surface of the main body portion 311 . The structure of the second supporting piece 340 is different from that of the first supporting piece 330. For example, the second supporting piece 340 is a straight structure and does not have an arc structure. The second supporting piece 340 can provide a flat load for the main body portion 311. noodle. It should be noted that the structure of the second supporting piece 340 may be the same as that of the first supporting piece 330 , which is convenient for processing.

It can be understood that in order to realize the stretching and bending of the display module, the display module can continuously change from flattening to bending according to the bending shape, and then from bending to flattening, which obviously can realize this. The material for the two state transitions is generally a flexible material, and the material must be in a stretched state, such as each layer of film material in the display module, but if there is only a flexible material, one end of the stretched bending part is stretched. In this state, the flexible material cannot be drawn according to the predetermined bending trajectory. Moreover, the display module cannot be directly subjected to force in a stretched state, because it is easy to cause damage to the display module. Obviously, in order to realize the expansion and contraction of the display module according to the predetermined trajectory at the bending position, and to ensure that the display body is not subjected to force alone, it is necessary to add a rigid structure in the bending area, but it is impossible to achieve expansion with a general rigid structure. Flat and bending are switched repeatedly. In the embodiment of the present application, by improving the structure of the first support piece 330, the first support piece 330 can be switched between the first bending state and the second bending state, so that the flexible screen can easily switch between the unfolded state and the retracted state. switch between.

It should be noted that the structure of the first support piece 330 is not limited thereto. For example, the first support piece 330 can be deformed in the width direction of the electronic device 20 so that the first support piece 330 moves on the outer surface of the shaft 200 It can be stretched during the process, so as to ensure that the first support piece 330 can easily support the expansion part 312 in the telescopic bending area and can realize telescopic bending during the movement along the outer surface of the shaft 200 without risk of damage. It can be understood that if the rigid sheet is directly arranged on the non-display surface of the extension part 312 , when the rigid sheet moves to the position of the axis 200 , insufficient tension may occur and the rigid sheet may break and be damaged. However, if a rubber member or a spring-type elastic member is directly used, the support for the extension part 312 may be insufficient due to excessive elasticity, which may cause wrinkles or dents in the flexible screen assembly 300 .

For example, as shown in FIG. 13 , FIG. 13 is a schematic diagram of a second partial structure of the first support piece and the second support piece provided by the embodiment of the present application. All or a part of the first supporting sheet 330 is provided with a plurality of mesh holes such as mesh 334 to improve the deformability of the first supporting sheet 330, for example, the first supporting sheet 330 can be etched with an acid etching solution, so that the first supporting sheet 330 can be etched in the first A plurality of diamond-shaped mesh holes 334 are etched on the support sheet 330, so that the first support sheet 330 has a diamond-shaped mesh structure, and the diamond-shaped mesh structure can make the first support sheet 330 have The ability to stretch. When the first supporting piece 330 moves in the width direction of the electronic device 20, the first supporting piece 330 will receive the extrusion force applied by the shaft 200 and the pulling force along the width direction of the electronic device 20, and the extrusion force Deformation can occur under the action of tension and tension. Compared with the rigid sheet, the first support sheet 330 in the embodiment of the present application can ensure that it will not be broken due to excessive tension during movement.

The mesh 334 can be in a regular shape, such as a diamond structure, a rectangular structure, etc., and the mesh 334 can also be in an irregular shape. For example, the mesh 334 in the embodiment of the present application is a rhombus structure, and the first support sheet makes all or a part of the first support sheet 330 form a diamond mesh structure. The advantage of the first support sheet 330 with the diamond mesh structure is flexibility. It is very good, and has great advantages in ensuring the flatness of the flexible screen assembly 300, and has a long bending life.

Wherein, when the size of the first support piece 330 is equal to the size of the extension part 312, the first support piece 330 can be processed into a diamond-shaped wire mesh structure; when the size of the first support piece 330 is larger than the extension part 312, the The part of the first support sheet 330 located on the non-display surface of the extension part 312 is processed into a diamond-shaped screen structure, and the other parts of the first support sheet 330 are flat rigid sheet structures, which do not need to be etched with an etching solution, such as the first support sheet 330 A portion located on the non-display surface of the main body portion 311 . It can be understood that the first support sheet 330 may include a first section and a second section, wherein the first section is arranged on the non-display surface of the main body part 311, the first section is a completed rigid sheet structure, and the surface has no mesh design. The second section is disposed on the non-display surface of the extension part 312 , and the second section is provided with a plurality of mesh holes 320 , and the mesh holes 320 are in a rhombus structure, so that the second section forms a rhombus mesh structure. Since during the movement of the first supporting piece 330, the part of the first supporting piece 330 located on the non-display surface of the extension part 312 is mainly under force, only a part of the first supporting piece 330 is processed into a diamond-shaped wire mesh structure, on the one hand The deformability of the first supporting piece 330 is ensured, on the other hand, the supporting strength of the entire first supporting piece 330 can be ensured, and the difficulty and cost of manufacturing can also be reduced.

As shown in combination with FIG. 8 and FIG. 14 , FIG. 14 is a second structural schematic view of the flexible screen assembly provided by the embodiment of the present application. The electronic device 20 further includes a protective layer 400, which may be a PI (Polyimide Film, polyimide film) film. Of course, the protective layer 400 can also be a film structure made of other materials, such as PET (Polyethyleneterephthalate, polyethylene terephthalate) film, PE (Polyethylene, polyethylene) film, and the like. The first support sheet 330 is sandwiched between the two protective layers 400, and the protective layer 400 covers the mesh 334 to block the mesh 334, so that objects (such as double-sided adhesive tape, Adhesives such as glue) will not penetrate into other parts through the mesh 334. For example, the first supporting sheet 330 may include a first side and a second side oppositely disposed, the first side is a side close to the non-display surface of the flexible screen assembly 300 , and the second side is a side away from the flexible screen assembly 300 . Wherein the first side is provided with a first protective layer 410, and the first protective layer 410 is covered on the mesh 334 to block the mesh 334 from the first side toward the second side; the second side is provided with a second protective layer 420, the second protective layer 420 is covered on the mesh hole 334 to block the mesh hole 334 from the second side toward the first side, so that the first supporting sheet 330 (including the first side and the second side) Objects (such as double-sided tape, glue and other adhesives) will not penetrate into the flexible screen assembly 300, or the middle frame, or the sliding part through the mesh 334.

In the embodiment of the present application, by providing the stretchable first support sheet 330 , not only can the tensile strength be increased, but also the risk of damage to the flexible screen assembly 300 can be reduced, and the service life of the flexible screen assembly 300 can be extended.

As shown in conjunction with FIG. 4 and FIG. 15 , FIG. 15 is a schematic structural diagram of the first slider and the second slider provided by the embodiment of the present application. The electronic device 20 can also include a first sliding part 510 and a second sliding part 520. For example, the first sliding part 510 can be arranged on the soft rubber connection belt 320 and is located on the main body part 311, and the second sliding part 520 can be arranged on the soft rubber connection belt. On the strap 320 and located on the extension 312 . Wherein, both the first sliding part 510 and the second sliding part 520 are slidably connected with the soft rubber connection belt 320, and both the first sliding part 510 and the second sliding part 520 are spaced apart from the shaft 200, the first sliding part 510 and the second sliding part The two sliding parts 520 can slide relative to the soft rubber connecting belt 320 along the surface of the soft rubber connecting belt 320 , so that the extension part 312 is deployed outside the casing 100 or stored inside the casing 100 according to the preset movement track.

In an initial state, the first sliding member 510 is located at the first position (as shown in FIG. 4 ), and the second sliding member 520 is located at the second position of the soft rubber connection strip 320 (as shown in FIG. 4 ). When the extension part 312 moves toward the outside of the casing 100, both the first sliding member 510 and the second sliding member 520 move toward the direction close to the shaft 200, so that the first sliding member 510 is located at the third position (as shown in FIG. 13 ), the second slider 520 is in the fourth position (as shown in FIG. 13 ), so that the extension part 312 outside the housing 100 can slide and unfold along the surface of the first slider 510, and the extension part 312 inside the housing 100 312 can slide along the surface of the second slider 520 to the surface of the shaft 200 . When the extension part 312 moves toward the inside of the casing 100, both the first slider 510 and the second slider 520 move toward a direction away from the shaft 200, so that the extension part 312 outside the casing 100 can slide along the first sliding direction. The surface of the member 510 slides to the surface of the shaft 200 , and the extension part 312 located in the housing 100 can slide into the housing 100 along the second sliding member 520 .

It can be understood that the first sliding member 510 can limit the movement of the extension portion 312 that gradually goes out of the outer surface of the shaft 200 (or goes into the outer surface of the shaft 200 ), and the second sliding member 520 can restrict the movement of the extension portion 312 that gradually goes around the outer surface of the shaft 200 . The extension part 312 on the surface (or around the outer surface of the shaft 200) performs movement restriction, thereby restricting the movement track of the entire extension part 312, so that the extension part 312 gradually expands outside the casing 100 according to the first preset movement track (or according to The second preset movement track is gradually recovered in the casing 100).

As shown in Figure 16, Figure 16 is a schematic cross-sectional structure diagram of the shaft and flexible screen assembly shown in Figure 2 along the P2-P2 direction, the first slider 510 and the second slider 520 are both provided with a sliding part such as a sliding part 530, sliding The size and shape of the portion 530 is adapted to the size and shape of the second limiting structure on the soft rubber connection belt 320 . For example, when the second limiting structure is a groove structure, the sliding part 530 may be a protruding structure; when the second limiting structure is a protruding structure, the sliding part 530 may be a groove structure.

The soft rubber connection belt 320 is provided with a limiting portion for limiting the sliding distance of the first sliding member 510 and the second sliding member 520 . For example, the soft rubber connection belt 320 is provided with a first limiting part and a second limiting part, the first limiting part is located between the first sliding part 510 and the shaft 200, and the first limiting part is used to limit the first sliding part 510 to prevent the first slider 510 from sliding excessively against the shaft 200; the second limiting part is located between the second sliding part 520 and the shaft 200, and the second limiting part is used to limit the movement of the second sliding part 520 The sliding distance is used to prevent the second sliding member 520 from sliding excessively and contacting the shaft 200 . Wherein, the limiting part may be a block, or a limiting screw or other components that can be used as a limiting obstacle.

In some embodiments, the soft rubber connection belt 320 can be provided with a plurality of telescopic stops, and the multiple telescopic stops are arranged at different positions of the soft rubber connection belt 320 at intervals, and the electronic device 20 can control the telescopic stoppers to protrude from the soft rubber The surface of the connecting strip 320 is retracted to the inside of the soft rubber connecting strip 320 . The user can choose the expansion size of the expansion part 312, such as selecting expansion 20%, expansion 50% or expansion 100%, etc., and the electronic device 20 controls the corresponding telescopic stopper to extend the soft rubber connection belt according to the expansion size selected by the user. 320 to stop the soft rubber connecting band 320 from continuing to move, thereby controlling the expanded size of the expansion part 312 . Compared with the roll-type flexible screen in the related art, the embodiment of the present application allows the user to freely choose the expansion size of the display screen according to their own needs, which is more intelligent and humanized.

It should be noted that the structure of the first sliding member 510 is not limited thereto. For example, when the size of the soft rubber connecting band 320 is equal to the size of the extension part 312 , the main body part 311 is not provided with a soft rubber connecting band. The first sliding member 510 may include a slide rail structure and a sliding structure that can slide along the slide rail structure. The first sliding member 510 may be made of rigid materials, such as wear-resistant and relatively rigid steel or metal. The outer surface of the slide rail structure is flush with the outer surface of the soft rubber connection belt 320, and the same protrusion or groove as the structure of the second limiting structure is provided on the slide rail structure, so that the slide structure can slide from the slide rail structure To the soft glue connection belt 320.

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

Engaged so that the drive motor 600 is connected to the shaft 200 , the drive shaft rotates under the drive of the drive motor 600 , and then drives the shaft 200 to rotate around the drive motor 600 . It can be understood that the driving motor 600 and the shaft 200 can jointly form a pulley motor device, and the shaft 200 rotates around the driving motor 600. Compared with setting the driving motor 600 outside the shaft 200, the embodiment of the present application can save The space occupied by the driving motor 600 on the electronic device 20 . Certainly, it is also possible that the driving motor 600 is arranged outside the shaft 200 and a fixing member is arranged inside the shaft 200 so that the driving motor 600 drives the shaft 200 to rotate around the fixing member.

When the driving motor 600 drives the shaft 200 to rotate clockwise, the soft rubber connection belt 320 is driven by the shaft 200 to move around the outer surface of the shaft 200 towards the outside of the housing 100, so that the expansion part 312 is gradually expanded outside the housing 100 ; When the driving motor 600 drives the shaft 200 to rotate counterclockwise, the soft rubber connection belt 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 part 312 is gradually recovered to the housing 100 internal. 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 then control the movement distance of the extension part 312, so that the size of the extension part 312 deployed outside the housing 100 can be adjusted, which can be interesting. Higher, enhance user experience.

The electronic device 20 may further include a second motor 800, the second motor 800 is connected to the soft rubber connection belt 320, and the second motor 800 may be used to drive the soft rubber connection belt 320 to move following the relative movement of the housing 100 and the shaft 200, and the A part of the flexible screen assembly 300 is recovered inside the housing 100 or a part of the flexible screen assembly 300 is unfolded 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 away from the housing 100, the second motor 800 can drive the soft rubber connection belt 320 to follow the shaft 200 after a preset interval, so that the expansion part originally accommodated inside the housing 100 312 slowly slides along the outer surface of the shaft 200 and gradually unfolds outside the casing 100 (or outside the electronic device 20 ) such as shown in FIG. The extension part 312 can display one screen together, or can display two screens separately. Compared with only using the main body part 311 in the initial state for display, expanding the extension part 312 outside the casing 100 can increase the electronic The display area of the device 20.

In the embodiment of the present application, two driving devices are provided to respectively control the movement states of the housing 100 , the shaft 200 and the soft rubber connection belt 320 , 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 present application can increase the display area of the electronic device 20 without additional installation space of the flexible screen assembly 300 (or display screen).

Please continue to refer to FIG. 22 and FIG. 24 , the second motor 800 is used to drive the soft rubber connection belt 320 to curl or stretch, so that the extension part 312 is stored in the casing 100 or unfolded outside the casing 100 . For example, one end of the soft rubber connection belt 320 is arranged on the output shaft of the second motor 800, and the other end of the soft rubber connection belt 320 is connected to the housing 100. Compared with connecting the flexible screen assembly 300 directly to the second motor 800 and the housing The body 100 is connected, and the embodiment of the present application can transfer the stretched object to the soft rubber connection belt 320, which can reduce the damage of the flexible screen assembly 300 during the stretching process.

When the electronic device 20 wants to control the flexible screen assembly 300 to expand out of the housing 100, the electronic device 20 can control the second motor 800 to drive the soft rubber connecting belt 320 to gradually change from a curled state to a stretched state, so that the extension part 312 can move along the The outer surface of the shaft 200 slides in a direction away from the second motor 800, so that the extension part 312 originally housed inside the casing 100 is gradually expanded outside the electronic device 20 (or casing 100), which is different from the original exposed portion 312 of the electronic device. 20 outside the main part 311 common display screen.

When the electronic device 20 wants to control the flexible screen assembly 300 to be accommodated in the casing 100, the electronic device 20 can control the second motor 800 to drive the soft rubber connecting belt 320 to gradually change from the stretched state to the curled state, so that the flexible screen assembly 300 can move along the The outer surface of the axis 200 slides slowly toward the second motor 800 to gradually retract the extension portion 312 originally deployed outside the electronic device 20 (or housing 100 ) into the housing 100 .

When the driving device 700 drives the housing 100 and the shaft 200 to move relative to each other, if the second motor 800 and the driving device 700 move simultaneously, the flexible screen assembly 300 will loosen, which may cause wrinkles or unevenness of the flexible screen assembly 300 . The defective phenomenon further affects the display effect of the screen of the electronic device 20 .

As shown in FIG. 25 , FIG. 25 is a sixth structural schematic diagram of an electronic device provided by an embodiment of the present application. In order to keep the flexible screen assembly 300 in a tight state all the time and ensure the tension of the flexible screen assembly 300, the processor of the electronic device 20 in the embodiment of the present application, such as the processor 900, is electrically connected to the driving device 700 and the second motor 800. connection, the processor 900 can be used to drive the drive device 700 to drive the relative movement of the casing 100 and the shaft 200 at different times, and the second motor 800 to drive the soft rubber connection belt 320 to follow the relative movement of the casing 100 and the shaft 200, so that the drive The device 700 and the second motor 800 are driven synchronously and asynchronously. It can be understood that there is a time difference between the driving time of the driving device 700 and the second motor 800, and this time difference is very short, which is mainly used to ensure that the two ends of the flexible screen assembly 300 are always in a tensioned state and ensure the flexibility of the flexible screen assembly 300. The tension ensures that there are no defects such as wrinkles and unevenness, so that the display effect of the screen of the electronic device 20 is not affected by the movement of the flexible screen assembly 300 .

For example, when the extension part 312 needs to be expanded, the processor 900 can control the driving device 700 to drive the shaft 200 to move away from the housing 100 at the first moment T1, so that the shaft 200 slowly protrudes out of the housing 100 to realize the Separation of body 100 and shaft 200 . When the shaft 200 moves to the second time T2, the processor 900 controls the second motor 800 to drive the soft rubber connection belt 320 to slowly unfold, so that the extension part 312 of the flexible screen assembly 300 can slide to the casing 100 along the outer surface of the shaft 200 outside. Wherein, the first time T1 is earlier than the second time T2, such as T2=T1+t1, t1 is the first preset interval time, the first preset interval time can be set according to the actual situation, the embodiment of the present application does not be limited. It can be understood that when the extension part 312 is unfolded, the shaft 200 moves before the soft rubber connection belt 320, so that the soft rubber connection belt 320 is always in a straight state, and then the flexible screen assembly 300 is gradually expanded in the expansion part 312 on the casing. 100 outside the process is always in a straight state.

When it is necessary to recover the extension part 312 into the housing 100, the processor 900 can control the second motor 800 to drive a part of the soft rubber connection belt 320 to curl slowly at the third moment T3, and the soft rubber connection belt 320 is driven during the curling process. The expansion part 312 moves toward the direction approaching the second motor 800 . When the flexible screen assembly 300 moves to the fourth time T4, the processor 900 controls the driving device 700 to drive the shaft 200 to move away from the housing 100, so that the shaft 200 slowly retracts into the housing 100, so that the housing 100 Fitting with shaft 200. Wherein, the third moment T3 is earlier than the fourth moment T4, for example, T4=T3+t2, t2 is the second preset interval time, the second preset interval time can be set according to the actual situation, and the embodiment of the present application does not be limited. It can be understood that, when the extension part 312 is recovered, the soft rubber connection belt 320 moves earlier than the shaft 200, so that the soft rubber connection belt 320 is always in a straight state, so that the flexible screen assembly 300 is gradually recovered to the casing at the extension part 312 The process within 100 is always in a straight state.

In some 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 rubber connection belt 320 . For example, a tension detector can be provided on the soft rubber connection belt 320 , and the tension detector is used to detect the tension value of the soft rubber connection belt 320 . When the expansion part 312 needs to be expanded, the processor 900 first controls the driving device 700 to start, and obtains the first tension value of the soft rubber connection belt 320 detected by the tension detector, when the first tension value of the soft rubber connection belt 320 is greater than the first tension value When a preset tension value is reached, the second motor 800 is controlled to start. Similarly, when the extension part 312 needs to be recovered, the processor 900 first controls the second motor 800 to start, and acquires the second tension value of the soft rubber connection belt 320 detected by the tension detector. When the second tension value is greater than the second preset tension value, the driving device is controlled to start. In the embodiment of the present application, the start-up time of the driving device 700 and the second motor 800 is determined according to the tension value of the soft rubber connecting belt 320, which can avoid excessive tension of the soft rubber connecting belt 320 due to too small a start time interval between the two. The situation that the flexible screen assembly 300 is wrinkled due to the small size can also avoid the damage caused by the excessive tension value of the soft rubber connection belt 320 due to the excessively long activation time interval between the two. Compared with the start-up control of the two driving devices according to a fixed time interval, the control in the embodiment of the present application is more accurate and intelligent.

One end of the soft rubber connecting belt 320 is connected to the housing 100, and the other end of the soft rubber connecting belt 320 is connected to the driving device 700. The driving device 700 drives the housing 100 and the shaft 200 to move relative to each other and drives the soft rubber connecting belt 320 to move, so that the expansion The part 312 protrudes from the casing 100 so that the extension part 312 and the main part 311 can display images together.

As shown in FIG. 27 and FIG. 28 , FIG. 27 is a schematic structural diagram of the driving device in the electronic device shown in FIG. 26 , and FIG. 28 is a structural schematic diagram of the pushing assembly in the driving device shown in FIG. 26 .

For example, the soft rubber connection belt 320 is sleeved on the rotating shaft 7222b and fixedly connected with both ends of the soft rubber connection belt 320 and the housing 100 .

When the extension part 312 needs to be expanded, the processor 900 can control the first motor 710 to drive the transmission assembly 721 to move, the transmission assembly 721 drives the push assembly 722 to move away from the housing 100, and the push assembly 722 passes through the push part 7222c during the movement The push shaft 200 also moves away from the housing 100. At the same time, since the rotating shaft 7222b also moves away from the housing 100, the soft rubber connection belt 320 also moves away from the housing 100 following the rotating shaft 7222b and along the The outer surface of the rotating shaft 7222b slides, thereby increasing the stretching length of the soft rubber connection belt 320 , and the extension part 312 slides out of the housing 100 under the drive of the soft rubber connection belt 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 can control the first motor 710 to drive the transmission assembly 721 to move, the transmission assembly 721 drives the push assembly 722 to move toward the direction close to the housing 100, and the push assembly 722 passes through the push part 7222c during the movement The pulling shaft 200 also moves towards the direction of the housing 100, and at the same time, because the rotation shaft 7222b also moves towards the direction of the housing 100, the soft rubber connection belt 320 also follows the rotation shaft 7222b and moves along the direction of the rotation shaft 7222b towards the direction of the housing 100. The outer surface of 7222b slides, thereby reducing the extension length of the soft rubber connecting belt 320 , and the extension part 312 slides into the housing 100 driven by the soft rubber connecting belt 320 , so that the extension part 312 is recovered to the inside of the housing 100 .

It should be noted that, when the expansion part 312 of the flexible screen assembly 300 is deployed outside the housing 100 or recovered into the housing 100 , the flexible screen assembly 300 is kept stretched under the joint action of the shaft 200 and the soft rubber connecting belt 320 .
