The flexible support member 220 may further include a first support sheet such as a first support sheet 222, and the first support sheet 222 may be made of a metal material, for example, the first support sheet may be a steel sheet, an aluminum sheet, a copper sheet, or the like. The first support sheet 222 is embedded in the interior of the soft adhesive connection tape 221 , for example, the soft adhesive connection tape 221 can be injection-molded on the first support sheet 222 , so that the first support sheet 222 is wrapped around the soft adhesive connection tape 221 . inside, so that the first support sheet 222 does not directly contact the flexible screen assembly 200 , so as to achieve the purpose of protecting the flexible screen assembly 200 .

In the initial state, the first support piece 222 is in the first state, and the first state is a state in which at least a part of the first support piece 222 is not in contact with the extension part 212 . When the surface of the shaft 500 and the first support piece 222 are in the radial direction of the shaft 500, an interaction force will be generated between the shaft 500 and the first support piece 222, so that the first support piece 222 is switched from the first state to the second state, and the second state is the first support The state that the sheet 222 is completely attached to the extension portion 212; when the soft adhesive connecting tape 221 and the extension portion 212 continue to move together, the soft adhesive connecting tape 221 and the extension portion 212 gradually move away from the surface of the shaft 500, the shaft 500 and the first supporting sheet The interaction force between the 222 gradually disappears. At this time, the first supporting piece 222 gradually returns to its original state, that is, the first supporting piece 222 is switched from the second state to the first state.

Wherein, when the first support piece 222 is in the first state, a part of the first support piece 222 is not in contact with the expansion part 212 , for example, the middle of the first support piece 222 may have a concave structure, and the two sides of the first support piece 222 In contact with the expanded portion 212, the middle of the first support sheet 222 has a gap with the expanded portion 212; it is also possible that the first support sheet 222 has a plurality of concave structures, and the first support sheet 222 has a portion with the concave structure and the expanded portion 212. When there is a gap, other parts of the first support sheet 222 are in contact with the extension part 212 or are in contact with the non-display surface of the extension part 212 . When the first support piece 222 is in the second state, since the first support piece 222 receives a force along the radial direction of the shaft 500 , the first support piece 222 is deformed, so that the original first support piece 222 does not expand with A part of the contact part of the part 212 is attached to the display surface of the extension part 212, so that the shape of the first support sheet 320 is consistent with the shape of the extension part 212, so as to ensure that the flexible screen assembly 200 can be repeatedly unfolded and retracted according to the preset movement track.

For example, the first support piece 222 may include a first side portion 2221, a second side portion 2222 and a recessed portion 2223, the recessed portion 2223 is located between the first side portion 2221 and the second side portion 2222, and the first side portion 2221 is located at the shaft One end of the shaft 500 , the second side portion 2222 is positioned at the other end of the shaft 500 , and the groove portion 513 is positioned at the middle of the shaft 500 . The concave portion 2223 is formed by bending from the display surface of the main body portion 211 toward the non-display surface of the main body portion 211 . It can be understood that the structure of the first support sheet 222 is similar to the structure of a tape measure, the cross section of the first support sheet 222 along the width direction of the electronic device 20 is an arc structure, and the bending direction of the first support sheet 222 faces away from Axis 500. When the soft adhesive connecting tape 221 moves along the outer surface of the shaft 500 , the first support piece 222 may be deformed to switch the recessed portion 2223 between the first bending state and the second bending state.

For example, in the initial state, the recessed portion 2223 is in a first bending state, which means that the recessed portion 2223 is bent from the display surface of the main body portion 211 to the non-display surface of the main body portion 211 . When the soft adhesive connecting tape 221 moves along the shaft 500, the soft adhesive connecting tape 221 moving to the position of the shaft 500 will abut against the shaft 500. During this process, the first supporting piece 222 located inside the soft adhesive connecting tape 221 The force along the radial direction of the shaft 500 can be received by the soft adhesive connecting tape 221 and deformed, so that the concave portion 2223 is switched from the first bending state to the second bending state, and the remaining first support pieces that are not in contact with the shaft 500 The part remains in its original shape, that is, in the first bending state. The second bending state means that the recessed portion 2223 is bent from the non-display surface of the main body portion 211 to the display surface of the main body portion 211 , so that the bending direction of the first support sheet 222 is the same as the curvature of the shaft 500 , thereby improving the soft glue The degree of fit between the connecting belt 221 and the shaft 500 makes the movement of the soft adhesive connecting belt 221 more stable. When the soft adhesive connecting tape 221 gradually moves to the outside of the housing assembly 100 or inside the housing assembly 100 along the direction of the outer surface of the shaft 500, the soft adhesive connecting tape originally in contact with the shaft 500 gradually moves away from the shaft 500, and the shaft 500 The pressing force on the first support piece 222 is also gradually cancelled, so that the concave portion 2223 is switched from the second bending state to the first bending state.

It can be understood that when the first support piece 222 is in a flattened state, the cross-sectional shape of the first support piece 222 is shown in FIG. 13 , and the first support piece 222 is in a concave shape in the flattened state, and only a little force is needed. The back surface can be deformed and turned into a straight shape, so that the shape of the first support piece 222 is the same as that of the expansion part 212 , so that the expansion part 212 can move along the surface of the shaft 500 . Based on the structure of the first support piece 222, the first support piece 222 can be deformed when it receives a force along the radial direction of the shaft 500, and is turned from a concave shape to a straight shape, as shown in FIG. 14; and The original concave shape is restored after receiving no force in the radial direction of the shaft 500 .

It should be noted that the structure of the first support sheet 222 is not limited to this. For example, the first support sheet 222 may have a plurality of concave portions 2223 , and the plurality of concave portions 2223 are arranged at intervals. The non-display surface of the main body portion 211 is bent and formed. When the expansion portion moves to the shaft 500, all or part of the concave portion 2223 is deformed when it receives a force along the radial direction of the shaft 500, so that the concave portion 2223 is deformed from the shaft 500. The non-display surface of the main body portion is curved toward the display surface of the main body portion, and at this time, the plurality of recessed portions 2223 are switched from the first curved state to the second curved state. When the extension portion 212 moves away from the shaft 500 , the recessed portion 2223 returns to a state of being bent from the display surface of the main body portion 211 toward the non-display surface of the main body portion 320 .

It can be understood that if the first support piece 222 is an ordinary straight rigid structure, when the first support piece 222 moves to the position of the shaft 500, due to the interaction between the shaft 500 and the first support piece 222 Force, the first support piece 222 will be deformed into a bent state, so that the first support piece 222 fits the outer surface of the shaft 500. When the first support piece 222 leaves the position of the shaft 500, the shaft 500 and the first support The interaction force between the sheets 222 disappears, but since the first support sheet 222 is a straight rigid structure, it cannot return to the original straight shape without the action of other forces after it is deformed. In the bent state, the extension portion 212 will also appear uneven, which affects the display effect of the electronic device 20 . However, the first support piece 222 of the present application can be switched between the first state and the second state, so that when the shaft 500 is in the position (or in the bending position), it is switched from the first state to the second state, and moves to other states. When in position, it switches from the second state back to the first state, that is, the expansion part 212 can be freely switched between the expanded state and the retracted state, and the expansion part 212 can be kept flat in both the expanded state and the retracted state, reducing the movement of the expansion part 212 The influence of the process on the display effect of the electronic device 20 .

In some other embodiments, the first support sheet 222 may also be directly disposed on the non-display surface of the extension portion 212 . The first support sheet 222 may be directly adhered to the non-display surface of the extension portion 212 using an adhesive such as double-sided tape or glue.

When the expansion portion 212 is located within the housing assembly 100 , a portion of the first support piece 222 abuts against the shaft 500 . For example, a part of the extension part 212 is in contact with the surface of the shaft 500, and there is a gap between a part of the extension part 212 and the shaft 500 (it can be understood that a part of the extension part 212 is not adjacent to the shaft 500). A part is in contact with the shaft 500 , and the other part of the first support piece 222 has a gap with the shaft 500 . It should be noted that the structure of the first support piece 222 is not limited to this. For example, the first support piece 222 may only be provided on the part of the expansion part 212 with a gap between the first support piece 222 and the shaft 500 , but not on the part with the shaft 500 . On the other part of the abutting extension part 212 , the first support piece 222 is spaced apart from the shaft 500 at this time, and does not abut with the shaft 500 .

When the expansion portion 212 is located outside the housing assembly 100 , a portion of the first support piece 222 abuts against the shaft 500 . For example, a part of the extension part 212 is in contact with the surface of the shaft 500, and there is a gap between a part of the extension part 212 and the shaft 500 (it can be understood that a part of the extension part 212 is not adjacent to the shaft 500). A part is in contact with the shaft 500 , and the other part of the first support piece 222 has a gap with the shaft 500 . It can be understood that at this time, a part of the expansion part 212 is laid flat on the outside of the housing assembly 100 , and a part of the expansion part 212 is sleeved on the surface of the shaft 500 . It should be noted that the structure of the first support piece 222 is not limited to this. For example, when the extension portion 212 is located outside the housing assembly 100 , the first support piece 222 may only be provided on the extension portion 212 with a gap between the shaft 500 and the extension portion 212 . The first support piece 222 is spaced apart from the shaft 500 and not in contact with the shaft 500 at this time.

The size of the first support sheet 222 may be greater than or equal to the size of the extension portion 212 . When the size of the first support sheet 222 is equal to the size of the extension portion 212 , the projection of the first support sheet 222 on the flexible screen assembly 200 is located at the extension portion 212 , so that the first support sheet 222 can cover the non-display surface of the entire extension portion 212 , and further support the entire extension portion 212 . Compared with the related art, the flexible screen is directly used as the main body for stretching. In the embodiment of the present application, the first support sheet 222 is provided in the extension part 212, and the extension part 212 can be in direct contact with the shaft 500 at intervals, thereby avoiding the non-display surface of the extension part 212. Wear on the extension 212 during direct friction with the outer surface of the shaft 500 . When the size of the first support sheet 222 is larger than the size of the extension part 212 , the projection of the first support sheet 222 on the flexible screen assembly 200 is partially located in the extension part 212 and part outside the extension part 212 , for example, it may be located on the main body part 211 , can also be located in the accommodating space of the housing assembly 100 .

When a portion of the first support sheet 222 is located on the main body portion 211 , the side outer surface of the first support sheet 222 is flush with the side outer surface of the main body portion 211 . For example, the first support piece 222 and the main body portion 211 are both cuboid structures, the first support piece 222 may have four mutually connected side portions, and the first support piece 222 has two opposite surfaces, and the two surfaces are connected at four sides. The two sides of each side part are enclosed to form a rectangular parallelepiped structure. Likewise, the main body portion 211 may also have four interconnected side portions and opposite display surfaces and non-display surfaces, wherein the first support sheet 222 is disposed on the non-display surface of the main body portion 211 , and the four The side outer surface is flush with the four side outer surfaces of the main body part 211 , and the first support sheet 222 can support the main body part 211 , so that the display surface of the main body part 211 is flatter and invisible from the outside. The first support sheet 222 keeps the appearance of the flexible screen assembly 200 simple.

It should be noted that the first support sheet 222 may not be located on the main body portion 211 , for example, as shown in FIG. 15 , which is a schematic diagram of the first partial structure of the first support sheet and the second support sheet provided by the embodiment of the application , the flexible support member 220 may further include a second support sheet 223 , and the second support sheet 223 is located on the non-display surface of the main body portion 211 . The structure of the second support piece 223 is different from that of the first support piece 222 . For example, the second support piece 223 is a straight structure and does not have an arc structure. The second support piece 223 can provide a flat bearing for the main body portion 211 . noodle. It should be noted that the structure of the second support sheet 223 may be the same as that of the first support sheet 222, which is convenient for processing.

It can be understood that, in order to realize that the flexible screen display module 210 is in the stretched and bent area, the flexible screen display module 210 can be continuously flattened to bent, and then bent to the flattened state according to the bending shape. Obviously, the materials that can realize these two state transitions are generally flexible materials, and the materials are required to be in a stretched state, such as the layers of film materials in the flexible screen display module 210, but if there are only flexible materials, the stretched and bent parts are , when one end of the flexible material is in a stretched state, the flexible material cannot be pulled according to the predetermined bending trajectory. In addition, the flexible screen display module 210 cannot be directly subjected to force in a stretched state, because this will easily cause the flexible screen display module 210 to be damaged. Obviously, in order to realize the expansion and contraction of the flexible screen display module 210 according to a predetermined trajectory at the bending position, and to ensure that the flexible screen display module 210 is not subjected to independent force, it is necessary to increase the attachment rigid structure in the bending area, but if the general rigidity is adopted The structure cannot be flattened and bent repeatedly. However, in the embodiment of the present application, the structure of the first support sheet 222 is improved, so that the first support sheet 222 can be switched between the first bending state and the second bending state, so that the flexible screen can be easily in the unfolded state and the retracted state. switch between.

It should be noted that the structure of the first support sheet 222 is not limited to this. For example, the first support sheet 222 may be deformed in the width direction of the electronic device 20 , so that the first support sheet 222 moves on the outer surface of the shaft 500 . During the process, it can be stretched, so as to ensure that the first support piece 222 can easily support the expansion part 212 in the telescopic bending area, and can achieve telescopic bending without risk of damage during movement along the outer surface of the shaft 500 . It can be understood that, if the rigid sheet is directly disposed on the non-display surface of the extension portion 212, the rigid sheet may be damaged due to insufficient tension when it moves to the position of the shaft 500. However, if a rubber member or a spring-type elastic member is directly used, the supporting force for the expansion portion 212 may be insufficient due to the excessive elasticity, which may lead to the occurrence of wrinkles or dents in the flexible screen assembly 200 .

For example, as shown in FIG. 16 , FIG. 16 is a schematic diagram of a second partial structure of the first support sheet and the second support sheet provided by the embodiment of the present application. All or a part of the first support sheet 222 is provided with a plurality of mesh holes such as mesh holes 2224 to improve the deformability of the first support sheet 222. A plurality of diamond-shaped mesh holes 2224 are etched on the support sheet 222, so that the first support sheet 222 has a diamond-shaped wire mesh structure. ability to stretch. When the first support sheet 222 moves in the width direction of the electronic device 20 , the first support sheet 222 receives the pressing force exerted by the shaft 500 and the pulling force along the width direction of the electronic device 20 . It can be deformed under the action of the tensile force, and compared with the rigid sheet, the first support sheet 222 in the embodiment of the present application can ensure that it will not be broken due to excessive tension during the movement.

The mesh holes 2224 may be of regular shape, such as a diamond-shaped structure, a rectangular structure, etc., and the mesh holes 2224 may also be of irregular shape. For example, the mesh 2224 in the embodiment of the present application is a diamond-shaped structure, for example, all or a part of the first support sheet 222 can be formed into a diamond-shaped wire mesh structure. The advantage of the first support sheet 222 with a diamond-shaped wire mesh structure is that the flexibility is very good , and has great advantages in ensuring the flatness of the flexible screen module module, and its bending life is long.

Wherein, when the size of the first support sheet 222 is equal to the size of the extension portion 212, the first support sheet 222 can be processed into a diamond-shaped wire mesh structure; when the size of the first support sheet 222 is larger than the size of the extension portion 212, the The part of the first support sheet 222 located on the non-display surface of the extension part 212 is processed into a diamond-shaped wire mesh structure, and the other parts of the first support sheet 222 are flat rigid sheet structures, which do not need to be etched with an etching solution, such as the first support sheet 222 A portion located on the non-display surface of the main body portion 211 . It can be understood that the first support sheet 222 may include a first section and a second section, wherein the first section is provided on the non-display surface of the main body portion 211, the first section is a complete rigid sheet structure, and the surface is designed without mesh holes. The second section is disposed on the non-display surface of the extension part 212, and the second section is provided with a plurality of mesh holes 320, and the mesh holes 320 are in a diamond-shaped structure, so that the second section forms a diamond-shaped wire mesh structure. During the movement of the first support sheet 222, the first support sheet 222 located on the non-display surface of the extension part 212 is mainly stressed, and only a part of the first support sheet 222 is processed into a diamond-shaped wire mesh structure. The deformability of the first support sheet 222 is ensured, and on the other hand, the support strength of the entire first support sheet 222 can be ensured, and the manufacturing difficulty and cost can be reduced.

Referring to FIG. 17, FIG. 17 is a schematic diagram of the second structure of the flexible screen assembly in the electronic device shown in FIG. 7. The flexible screen assembly 200 may further include a protective layer such as a protective layer 224, and the protective layer 224 may be PI (PolyimideFilm, polyimide film). imide film) film. Of course, the protective layer 224 can also be a film structure made of other materials, such as a PET (Polyethyleneterephthalate, polyethylene terephthalate) film, a PE (Polyethylene, polyethylene) film, and the like. The first support sheet 222 is sandwiched between the two protective layers 224, and the protective layer 224 covers the mesh holes 2224 to block the mesh holes 2224, so that objects (such as double-sided tape, Adhesives such as glue) will not penetrate into other components through the mesh 2224. For example, the first support sheet 222 may include a first side surface and a second side surface disposed opposite to each other. The first protective layer 2241 is provided on the first side, and the first protective layer 2241 is covered on the mesh hole 2224 to block the mesh hole 2224 from the first side to the second side; the second side is provided with a second protective layer 2242, the second protective layer 2242 is covered on the mesh hole 2224 to block the mesh hole 2224 from the second side to the direction of the first side, so as to be arranged on the first support sheet 222 (including the first side and the second side) The objects (such as double-sided tape, glue and other adhesives) will not penetrate into the flexible screen assembly 200, or the middle frame, or the sliding member through the mesh 2224.

By providing the stretchable first support sheet 222 in the embodiment of the present application, not only the tensile strength can be increased, but also the damage risk of the flexible screen assembly 200 can be reduced, and the service life of the flexible screen assembly 200 can be prolonged.

Please continue to refer to FIG. 7 , the shaft 500 can be a cylindrical structure, and the outer surface of the shaft 500 is further provided with a first limiting structure such as a first limiting structure, and the first limiting structure can be arranged around the periphery of the outer surface of the shaft 500 ring structure. The number of the first limiting structures may be multiple, the plurality of first limiting structures may be arranged at intervals, and the number of the first limiting structures may also be one. The first limiting structure may be a protruding structure disposed on the outer surface of the shaft 500 and protruding from the outer surface of the shaft 500, the first limiting structure may also be a groove structure provided on the outer surface of the shaft 500, or when When there are multiple first limiting structures, a part of the first limiting structures may be protruding structures, and another part of the first limiting structures may be groove structures. It should be noted that the shaft 500 may also have an irregular structure, for example, a part of the surface of the shaft 500 is an arc structure, and a part of the surface is a square structure.

The soft adhesive connecting tape 221 is provided with a second limiting structure, the second limiting structure is disposed on the side of the soft adhesive connecting tape 221 away from the expansion part 212 , and the second limiting structure may match the first limiting structure. For example: when the first limiting structure is a protruding structure, the second limiting structure can be a groove structure. At this time, the first limiting structure can be accommodated in the second limiting structure, and is connected with the second limiting structure. The interference fit connection makes the soft rubber connecting belt 221 move according to the preset motion trajectory under the limiting action of the first limiting structure and the second limiting structure (for example, linear motion along the direction parallel to the housing assembly 100 ), Then, the expansion part 212 is moved to the outside of the casing assembly 100 or the inside of the casing assembly 100 according to the preset movement track. Another example: when the first limiting structure is a groove structure, the second limiting structure can be a protruding structure, and at this time, the second limiting structure can be accommodated in the first limiting structure, and is connected with the first limiting structure. The groove walls of the structure are connected by an interference fit. Also for example: when the number of the first limiting structures is multiple, a part of the first limiting structures is a protruding structure, and a part of the first limiting structures is a groove structure, correspondingly, it can be arranged on the outer surface of the soft adhesive connecting tape 221. There are a plurality of second limiting structures, wherein a part of the second limiting structures is matched with the protruding structure, and a part of the second limiting structures is matched with the groove structure. It can be understood that the shapes and sizes of the first limiting structure and the second limiting structure are matched with each other and abut each other, so as to limit the movement path of the soft adhesive connecting tape 221 .

For example, in conjunction with FIG. 7 and FIG. 18 , FIG. 18 is a schematic cross-sectional structure diagram of the flexible screen assembly and the axis along the P4-P4 direction shown in FIG. 9 . The first limiting structure includes a limiting groove 510 , the limiting groove 510 is arranged around the outer surface of the shaft 500 , and the groove width of the limiting groove 510 gradually narrows from the outer surface of the shaft 500 to the inner surface of the shaft 500 . . The second limiting structure may include a limiting protrusion 2211 , the limiting protrusion 2211 is disposed on the outer surface of the soft adhesive connecting tape 221 and protrudes from the surface of the soft adhesive connecting tape 221 , and the outer surface of the soft adhesive connecting tape 221 refers to The inner surface of the soft adhesive connecting tape 221 refers to the side connected to the non-display surface of the flexible screen assembly 200 . The material of the limiting protrusions 2211 is the same as the material of the soft adhesive connecting tape 221 , such as rubber, and the width of the limiting protrusions 2211 is from the inner surface of the soft adhesive connecting tape 221 to the outer surface of the soft adhesive connecting tape 221 The direction is gradually widened, so that the shape of the limit protrusion 2211 can match the shape of the limit groove 510, the limit protrusion 2211 can be embedded in the limit groove 510, and the limit protrusion 2211 can pass the limit The groove 510 restricts the movement trajectory of the flexible screen assembly 200 , so that the extension portion 212 moves into the casing assembly 100 or outside the casing assembly 100 according to a preset trajectory. The limit protrusion 2211 is connected with the limit groove 510 by interference fit. For example, the size of the limit protrusion 2211 is slightly larger than the size of the limit groove 510, so that when the limit protrusion 2211 is installed in the limit groove 510, The outer surface of the limit protrusion 2211 and the groove wall of the limit groove 510 are pressed against each other, so as to increase the abutment firmness of the limit groove 510 and the limit protrusion 2211, and also increase the shaft 500 and the soft adhesive connection tape. The coefficient of friction between 221 forms an effective friction zone between the shaft 500 and the soft rubber connecting belt 221 .

It can be understood that, if the coefficient of friction between the shaft 500 and the soft rubber connecting belt 221 is too small, the phenomenon of slippage may occur during the movement of the soft rubber connecting belt 221 around the shaft 500, thereby causing the expansion part 212 to expand. Not smooth with storage. In the embodiment of the present application, the limiting groove 510 and the limiting protrusion 2211 can make the soft adhesive connection tape 221 difficult to slide, thereby ensuring the display reliability of the flexible screen assembly 200 . It should be noted that the shape of the limiting groove 510 is not limited to this, for example, the limiting groove 510 may also be a dovetail groove, a square groove, or the like.

In the embodiment of the present application, through the cooperation of the first limiting structure and the second limiting structure, the flexible screen assembly 200 can be deployed outside the casing assembly 100 or stored in the casing assembly 100 according to a preset motion trajectory. In the related art, the embodiment of the present application can prevent the flexible screen assembly 200 from being offset during the expansion process, thereby preventing the flexible screen assembly 200 from being pulled in the length direction of the electronic device 20, and further protecting the flexible screen assembly 200 from damage.

Referring to FIG. 7 and FIG. 19 , FIG. 19 is a schematic structural diagram of a first sliding member and a second sliding member provided by an embodiment of the present application. The electronic device 20 may further include a first sliding member 710 and a second sliding member 720. For example, the first sliding member 710 may be disposed on the soft adhesive connecting tape 221 and located on the main body portion 310, and the second sliding member 720 may be disposed on the soft adhesive connecting belt 221. On the strap 221 and on the extension 212 . Wherein, the first sliding member 710 and the second sliding member 720 are both slidably connected with the soft adhesive connecting tape 221 , and the first sliding member 710 and the second sliding member 720 are spaced apart from the shaft 500 . Both of the two sliding members 720 can slide relative to the soft adhesive connection tape 221 along the surface of the soft adhesive connection tape 221 , so that the extension portion 212 can be unfolded outside the casing assembly 100 or stored in the casing assembly 100 according to the preset motion trajectory. internal.

In the initial state, the first sliding member 710 is located at the first position (as shown in FIG. 7 ), and the second sliding member 720 is located at the second position (as shown in FIG. 7 ) of the soft adhesive connecting tape 221 .
