Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure, and fig. 2 is a partial structural schematic diagram of the electronic device shown in fig. 1. An electronic device such as electronic device 20 of fig. 1 may be a computing device such as a laptop computer, a computer monitor containing an embedded computer, a tablet, a cellular telephone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a hanging device, an earphone or headphone device, a device embedded in eyeglasses, or other device worn on the head of a user, or other wearable or miniature device), a television, a computer display not containing an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or automobile), a device that implements the functionality of two or more of these devices, or other electronic devices. In the exemplary configuration of fig. 1, the electronic device 20 is a portable device, such as a cellular telephone, media player, tablet, or other portable computing device. Other configurations may be used for the electronic device 20, if desired. The example of fig. 1 is merely exemplary.

The electronic device 20 may include a housing assembly, such as the housing assembly 100, and the housing assembly 100 may be formed from plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The shell assembly 100 may be formed using a one-piece configuration in which some or all of the shell assembly 100 is machined or molded as a single structure, or may be formed using multiple structures (e.g., an inner frame structure, one or more structures that form an outer shell surface, etc.).

Among other things, the housing assembly 100 may be a regular shape, such as a rectangular parallelepiped structure, a rounded rectangular structure. The housing assembly 100 may include a main body portion such as the main body portion 110 and a movable portion such as the movable portion 120, the main body portion 110 and the movable portion 120 being movably connected such that the movable portion 120 may be transitioned between the first state and the second state. When the movable portion 120 is in the first state, the movable portion 120 and the main body portion 110 may be connected in an abutting manner or an abutting manner, or may be connected in other manners, such as fastening, clamping, and the like. When the movable portion 120 is in the second state, there is an active space between the movable portion 120 and the main body portion 110, which may provide a movement space for a flexible screen assembly, such as the flexible screen assembly 200. For example, the flexible screen assembly 200 may be moved through the active space to deploy a portion of the flexible screen assembly 200 outside the housing assembly 100 or to retract a portion of the flexible screen assembly 200 inside the housing assembly 100. Wherein, the movable part 120 can be switched between the second state and the first state by manually drawing the movable part 120; the movable portion 120 may be driven to switch between the second state and the first state by an electronic driving method. The above description is merely an example of the mode of switching the state of the movable portion 120, and the mode of switching the state of the movable portion 120 is not to be construed as limiting.

It is understood that if the activity space is not provided, the flexible screen assembly 200 may contact and rub against the housing assembly 100 during the movement, thereby causing damage to the flexible screen assembly 200; if the gap is directly formed around the flexible screen assembly 200, so that the flexible screen assembly 200 is isolated from the housing assembly 100, the space of the housing assembly 100 is wasted, and an additional shielding member is required to shield the gap between the housing assembly 100 and the flexible screen assembly 200 from the appearance, which undoubtedly increases the volume of the housing assembly 100. In the embodiment of the present application, the housing assembly 100 is separated into the main body portion 110 and the movable portion 120, when the flexible screen assembly 200 moves, the movable portion 120 can be in the second state, at this time, a certain distance exists between the movable portion 120 and the flexible screen assembly 200, and then the flexible screen assembly 200 moves, so that the risk of friction between the flexible screen assembly 200 and the housing assembly 100 due to stretching and retracting actions can be directly avoided, further wear of the flexible screen assembly 200 during the movement process can be reduced, the service life of the flexible screen assembly 200 is prolonged, and the movable portion 120 can be connected with the main body portion 110 after the stretching and retracting actions are completed, so that the movable space cannot be seen from the appearance surface, and other objects can be prevented from entering the housing assembly 100 through the movable space.

It can be understood that, during the process of moving the flexible screen assembly 200 along the outer surface of the shaft 500, the movable portion 120 may be in the second state, and then the flexible screen assembly 200 is moved along the outer surface of the shaft 500, so that the display surface of the flexible screen assembly 200 is not damaged due to direct contact and friction with the movable portion 120.

Wherein a projection of the movable portion 120 on the flexible screen assembly 200 at least partially overlaps a projection of the shaft 500 on the flexible screen assembly 200. The projection of the movable portion 120 on the flexible panel assembly 200 refers to the projection when the projection direction is parallel to the main body portion 110, and the projection of the shaft 500 on the flexible panel assembly 200 refers to the projection when the projection direction is parallel to the main body portion 110. It is understood that when the flexible screen assembly 200 is fitted over the shaft 500, the flexible screen assembly 200 forms a bending region, and the movable portion 120 is located at a position corresponding to the bending region. Moreover, the outer surface of the movable portion 120 is flush with the outer surface of the main body portion 211, for example, the portion of the movable portion 120 located on the display surface of the electronic device 20 is flush with the display surface of the main body portion 211, which can improve the aesthetic appearance of the electronic device.

The flexible screen assembly 200 may include a narrow screen mode as shown in fig. 1 in which the display area of the flexible screen assembly 200 is fixed and a wide screen mode as shown in fig. 6; in the wide screen mode, the display area of the flexible screen assembly 200 may be expanded. For example, the flexible display module 210 may include a main body portion 211 and an extension portion 212, the main body portion 211 is fixedly connected with the housing assembly 100, the extension portion 212 abuts a shaft such as the shaft 500 and the extension portion 212 is movable along an outer surface of the shaft 500, such that the extension portion 212 may be deployed outside the housing assembly 100 or retracted inside the housing assembly 100.

When the flexible screen assembly 200 is in the narrow screen mode or the wide screen mode, the main body portion 211 is always fixed on the outer surface of the housing assembly 100 to be exposed outside the electronic device 20, at this time, the extension portion 212 is in a storage state, at this time, the extension portion 212 is hidden inside the housing assembly 100 and cannot be used for displaying information, and only the main body portion 211 of the flexible screen assembly 200 is used for displaying information; when the flexible screen is switched from the narrow-screen mode to the wide-screen mode, a user may pull the movable portion 120 to move in a direction away from the main body portion 110 (or may set a driving mechanism to drive the movable portion 120 to move), and then drive at least a portion of the extension portion 212 to gradually rotate out of the housing assembly 100 along the outer surface of the shaft 500, at this time, at least a portion of the extension portion 212 is exposed outside the housing assembly 100, so that the narrow-screen mode is switched to the wide-screen mode. The expansion portion 212 exposed to the outside may display information together with the main body portion 211, and a display area may be increased relative to the information display using only the main body portion 211. When the flexible screen assembly 200 is switched from the wide screen mode to the narrow screen mode, the expansion portion 212 may be gradually rotated into the interior of the housing assembly 100 along the outer surface of the shaft 500 in a direction close to the housing assembly 100 (the expansion or storage of the flexible screen assembly 200 may be achieved by a manual driving manner or a mechanical driving manner), so that at least a portion of the expansion portion 212 is stored in the housing assembly 100, and after the switching is completed, the movable portion 120 is pushed to move in a direction close to the main body portion 110, so that the movable portion 120 is connected with the main body portion 110 (or the reciprocating movement of the movable portion 120 may be driven by a mechanical driving manner).

The flexible support 220 may include a soft glue string, a metal sheet, etc. For example, as shown in fig. 7, fig. 7 is a schematic view of a partial structure of the electronic device shown in fig. 1. The flexible supporting member 220 may include a soft rubber connecting band such as the soft rubber connecting band 221, and the hardness (shore a) of the soft rubber connecting band 221 is (60-75 degrees), such as 65 degrees, 68 degrees, 70 degrees, or 75 degrees, and the like. The soft adhesive connecting tape 221 may be made of rubber, silicone, TPU (Thermoplastic polyurethane elastomer rubber), or the like. The soft adhesive connecting band 221 is arranged on the non-display surface of the expansion part 212, and the soft adhesive connecting band 221 can provide a flat bearing surface for the expansion part 212, so that the expansion part 212 can be unfolded flatly without the bad phenomenon of folds or depressions. Compared with a rigid material, the hardness of the soft rubber connecting belt 221 adopted in the embodiment of the application is 60-75 degrees, so that the damage to the extension part 212 in the movement process of the soft rubber connecting belt 221 can be reduced, and the contact surface between the extension part 212 and the soft rubber connecting belt 221 is protected from being worn easily. In addition, the expansion part 212 is easily broken because the expansion part 212 may frequently generate friction with the shaft 500 during the movement. In the embodiment of the application, the soft rubber connecting belt 221 is additionally arranged on the extension part 212 which needs to move, so that the friction force which originally acts on the extension part 212 can be transferred to the soft rubber connecting belt 221, and the extension part 212 can be further protected.

As shown in fig. 8, fig. 8 is a schematic view of a first partial structure of the flexible screen assembly and the shaft in the electronic device shown in fig. 7, a size of the soft glue connection band 221 is equal to a size of the extension portion 212, and a projection of the soft glue connection band 221 on the flexible screen assembly 200 is located on the extension portion 212, so that the soft glue connection band 221 can cover a non-display surface of the entire extension portion 212, thereby protecting the entire extension portion 212. Compared with the related art, the flexible screen is directly used as a stretching main body, the soft rubber connecting belt 221 is arranged on the expansion part 212, the expansion part 212 can be in direct contact with the shaft 500 at intervals, and abrasion to the expansion part 212 in the process that the non-display surface of the expansion part 212 is directly rubbed with the outer surface of the shaft 500 is avoided.

In other embodiments, such as shown in fig. 9, fig. 9 is a second partial structural schematic view of the flexible screen assembly and the shaft of the electronic device shown in fig. 7. The size of the soft glue connection strip 221 may also be larger than the size of the extension 212. When the size of the soft rubber connecting band 221 is larger than that of the extension part 212, a part of the projection of the soft rubber connecting band 221 on the flexible screen assembly 200 is located on the extension part 212, and a part of the projection is located outside the extension part 212, for example, the projection can be located on the main body part 211, or can be located in the accommodating space of the housing assembly 100, for example, the projection can be used for connecting a driving motor, and the driving motor drives the extension part 212 to be unfolded or recovered by driving the part of the soft rubber connecting band 221, which is located in the accommodating space of the housing assembly 100, to be curled or unfolded.

When a portion of the soft adhesive tape 221 is located at the main body part 211, the outer surface of the side of the soft adhesive tape 221 is flush with the outer surface of the side of the main body part 211. For example, soft glue connecting band 221 and main part 211 are the cuboid structure, and soft glue connecting band 221 can have four interconnect's lateral part, and soft glue connecting band 221 has two relative surfaces, and two surface connections are in order to enclose the both sides of four lateral parts and establish formation cuboid structure. Similarly, the main body part 211 may also have four mutually connected side portions, and a display surface and a non-display surface opposite to each other, wherein the soft rubber connection band 221 is disposed on the non-display surface of the main body part 211, four outer surfaces of the side portions of the soft rubber connection band 221 are flush with four outer surfaces of the side portions of the main body part 211, the soft rubber connection band 221 may support the main body part 211, so that the display surface of the main body part 211 is smoother, and the soft rubber connection band 221 is not observed from the outside, thereby maintaining the appearance simplicity of the flexible screen assembly 200.

As shown in fig. 10 to 14, fig. 10 is a first structural schematic diagram of a flexible screen assembly in the electronic device shown in fig. 7, fig. 11 is a structural schematic diagram of a first supporting sheet in the flexible screen assembly shown in fig. 10, fig. 12 is a partial structural schematic diagram of the first supporting sheet shown in fig. 10, fig. 13 is a sectional structural schematic diagram of the first supporting sheet shown in fig. 11 along P4-P4, and fig. 14 is a sectional structural schematic diagram of the first supporting sheet shown in fig. 11 along P5-P5.

The flexible supporting member 220 may further include a first supporting sheet such as a first supporting sheet 222, and the first supporting sheet 222 may be made of a metal material, for example, the first supporting sheet may be a steel sheet, an aluminum sheet, a copper sheet, or the like. The first supporting sheet 222 is embedded in the soft rubber connecting band 221, for example, a mode of injection molding the first supporting sheet 222 to form the soft rubber connecting band 221 can be adopted, so that the first supporting sheet 222 is wrapped in the soft rubber connecting band 221, and the first supporting sheet 222 is not directly contacted with the flexible screen assembly 200, thereby achieving the purpose of protecting the flexible screen assembly 200.

In an initial state, the first support sheet 222 is in a first state, the first state is a state in which at least a part of the first support sheet 222 is not in contact with the extension part 212, when the soft rubber connecting band 221 moves to the surface of the shaft 500 together with the extension part 212, an interaction force along the radial direction of the shaft 500 is generated between the shaft 500 and the first support sheet 222, so that the first support sheet 222 is switched from the first state to a second state, and the second state is a state in which the first support sheet 222 is completely attached to the extension part 212; when the soft rubber connecting band 221 and the extension part 212 continue to move together, the soft rubber connecting band 221 and the extension part 212 gradually move away from the surface of the shaft 500, the interaction force between the shaft 500 and the first supporting sheet 222 gradually disappears, and at this time, the first supporting sheet 222 gradually recovers, that is, the first supporting sheet 222 is switched from the second state to the first state.

When the first supporting sheet 222 is in the first state, a part of the first supporting sheet 222 is not in contact with the expansion part 212, for example, the middle of the first supporting sheet 222 has a concave structure, two sides of the first supporting sheet 222 are in contact with the expansion part 212, and the middle of the first supporting sheet 222 has a gap with the expansion part 212; it is also possible that the first support sheet 222 has a plurality of concave structures, the first support sheet 222 has a gap with the extension portion 212 at a portion having the concave structures, and other portions of the first support sheet 222 are in contact with the extension portion 212 or in contact with the non-display surface of the extension portion 212. When the first supporting sheet 222 is in the second state, the first supporting sheet 222 receives the radial acting force along the shaft 500, so that the first supporting sheet 222 deforms, and a part of the first supporting sheet 222, which is not in contact with the extension portion 212, is attached to the display surface of the extension portion 212, so that the shape of the first supporting sheet 320 is consistent with that of the extension portion 212, and the flexible screen assembly 200 can be repeatedly unfolded and recovered according to a preset movement track.

For example, the first support sheet 222 may include a first side portion 2221, a second side portion 2222, and a recess portion 2223, the recess portion 2223 being located between the first side portion 2221 and the second side portion 2222, the first side portion 2221 being located at one end portion of the shaft 500, the second side portion 2222 being located at the other end portion of the shaft 500, and the groove portion 513 being located at an intermediate position of the shaft 500. Wherein the recess 2223 is formed to be curved from the display surface of the main body portion 211 toward the non-display surface of the main body portion 211. It will be appreciated that the first support sheet 222 is similar in structure to a tape measure, the first support sheet 222 having an arcuate cross-section along the width of the electronic device 20, and the first support sheet 222 being curved away from the axis 500. When the flexible glue connection strap 221 moves along the outer surface of the shaft 500, the first support sheet 222 may be deformed to switch the recess 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 curved state, which means that the recessed portion 2223 is curved from the display surface of the main body portion 211 toward the non-display surface of the main body portion 211. When the soft rubber connecting band 221 moves along the shaft 500, the soft rubber connecting band 221 moving to the shaft 500 can abut against the shaft 500, and in the process, the first supporting sheet 222 located inside the soft rubber connecting band 221 can receive the radial acting force along the shaft 500 through the soft rubber connecting band 221 and deform, so that the concave portion 2223 is switched to the second bending state from the first bending state, and the rest of the first supporting sheet which is not abutted against the shaft 500 keeps the original state, namely, is in the first bending state. The second bending state refers to that the recessed portion 2223 is bent from the non-display surface of the main body part 211 to the display surface of the main body part 211, so that the bending direction of the first support sheet 222 is the same as the radian of the shaft 500, the fitting degree of the soft rubber connecting band 221 and the shaft 500 is further improved, and the movement of the soft rubber connecting band 221 is more stable. When the flexible glue connecting band 221 gradually moves to the outside of the housing assembly 100 or the inside of the housing assembly 100 along the outer surface direction of the shaft 500, the flexible glue connecting band originally abutted to the shaft 500 gradually moves away from the shaft 500, and at this time, the extrusion acting force of the shaft 500 to the first supporting sheet 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 supporting sheet 222 is in the flat state, the cross-sectional shape of the first supporting sheet 222 is as shown in fig. 13, and the first supporting sheet 222 is concave in the flat state, and only needs to push the back surface of the first supporting sheet 222 with a little force, the first supporting sheet can be deformed and turned into a straight shape, so that the shape of the first supporting sheet 222 is the same as that of the extension portion 212, and the extension portion 212 can move along the surface of the shaft 500. Based on the structure of the first supporting sheet 222, the first supporting sheet 222 can be deformed when receiving a force along the radial direction of the shaft 500, and can be turned from a concave shape to a straight shape, as shown in fig. 14; and returns to the original concave shape after receiving no force in the radial direction of the shaft 500.

It should be noted that the structure of the first supporting sheet 222 is not limited to this, for example, the first supporting sheet 222 may have a plurality of concave portions 2223, the plurality of concave portions 2223 are arranged at intervals, one 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, when the expanding portion moves onto the shaft 500, all or part of the concave portions 2223 are deformed by a force along the radial direction of the shaft 500, so that the concave portions 2223 are bent from the non-display surface of the main body portion toward the display surface of the main body portion, and at this time, the plurality of concave portions 2223 are switched from the first bending state to the second bending state. When the expanding portion 212 is away from the shaft 500, the recess 2223 is restored 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 supporting sheet 222 is a common flat rigid structure, when the first supporting sheet 222 moves to the position of the shaft 500, due to the interaction force between the shaft 500 and the first supporting sheet 222, the first supporting sheet 222 is deformed into a bent state and the first supporting sheet 222 fits the outer surface of the shaft 500, when the first supporting sheet 222 leaves the position of the shaft 500, the interaction force between the shaft 500 and the first supporting sheet 222 disappears, but because the first supporting sheet 222 is a flat rigid structure, the first supporting sheet 222 cannot restore the original flat state without other forces after deformation, for example, the original bent state can be presented, and thus the expansion portion 212 can also present an uneven condition and affect the display effect of the electronic device 20. The first supporting sheet 222 of the present application can be switched between the first state and the second state, so that when the shaft 500 is located (or bent), the first state is switched to the second state, and when the shaft is moved to another position, the second state is switched back to the first state, that is, the expansion portion 212 can be freely switched between the expanded state and the retracted state, and the expansion portion 212 can be kept flat both in the expanded state and the retracted state, so as to reduce the influence of the movement process of the expansion portion 212 on the display effect of the electronic device 20.

In other embodiments, the first supporting sheet 222 may be directly disposed on the non-display surface of the expansion 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 a double-sided tape or glue.

When the extension portion 212 is positioned within the housing assembly 100, a portion of the first support tab 222 abuts the shaft 500. For example, a portion of the extension 212 abuts a surface of the shaft 500 with a gap between a portion of the extension 212 and the shaft 500 (it is understood that a portion of the extension 212 is not adjacent to the shaft 500), while a portion of the first support sheet 222 abuts the shaft 500 and another portion of the first support sheet 222 has a gap from the shaft 500. It should be noted that the structure of the first support sheet 222 is not limited to this, and for example, the first support sheet 222 may be provided only on a portion of the expanded portion 212 having a gap with the shaft 500, and not on another portion of the expanded portion 212 abutting against the shaft 500, in which case the first support sheet 222 is provided spaced from the shaft 500, and does not abut against the shaft 500.

When the extension portion 212 is positioned outside the housing assembly 100, a portion of the first support sheet 222 abuts the shaft 500. For example, a portion of the extension 212 abuts a surface of the shaft 500 with a gap between a portion of the extension 212 and the shaft 500 (it is understood that a portion of the extension 212 is not adjacent to the shaft 500), while a portion of the first support sheet 222 abuts the shaft 500 and another portion of the first support sheet 222 has a gap from the shaft 500. It will be appreciated that a portion of extension 212 now lies flat outside housing assembly 100, and a portion of extension 212 fits over the surface of shaft 500. It should be noted that the structure of the first support sheet 222 is not limited thereto, for example, when the expanded portion 212 is located outside the housing assembly 100, the first support sheet 222 may be provided only on a portion of the expanded portion 212 having a gap with the shaft 500, and not on another portion of the expanded portion 212 abutting against the shaft 500, in which case the first support sheet 222 is provided spaced apart from the shaft 500, and does not abut against the shaft 500.

The size of the first support sheet 222 may be greater than or equal to the size of the extension portion 212, and 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 on the extension portion 212, so that the first support sheet 222 may cover the whole non-display surface of the extension portion 212, thereby supporting the whole extension portion 212. Compared with the related art, the flexible screen is directly used as a stretching main body, the first supporting sheet 222 is arranged on the expansion part 212 in the embodiment of the application, the expansion part 212 can be in direct contact with the shaft 500 at intervals, and therefore abrasion to the expansion part 212 in the process that the non-display surface of the expansion part 212 and the outer surface of the shaft 500 rub against each other directly is avoided. When the size of the first supporting sheet 222 is larger than that of the extension portion 212, a part of a projection of the first supporting sheet 222 on the flexible screen assembly 200 is located on the extension portion 212, and a part of the projection is located outside the extension portion 212, for example, the first supporting sheet may be located on the main body portion 211, or may be located in the accommodating space of the housing assembly 100.

When a portion of the first support sheet 222 is located at the body portion 211, the side outer surface of the first support sheet 222 is flush with the side outer surface of the body portion 211. For example, the first supporting sheet 222 and the main body portion 211 are both rectangular parallelepiped structures, the first supporting sheet 222 may have four sides connected to each other, and the first supporting sheet 222 has two opposite surfaces connected to two sides of the four sides to form a rectangular parallelepiped structure. Similarly, the main body portion 211 may also have four sides connected to each other and an opposite display surface and a non-display surface, wherein the first supporting sheet 222 is disposed on the non-display surface of the main body portion 211, four outer side surfaces of the first supporting sheet 222 are flush with the four outer side surfaces of the main body portion 211, and the first supporting sheet 222 may support the main body portion 211, so that the display surface of the main body portion 211 is flatter, and the first supporting sheet 222 is not visible from the outside, thereby maintaining the appearance simplicity of the flexible screen assembly 200.

It should be noted that the first supporting sheet 222 may not be located on the main body portion 211, for example, as shown in fig. 15, fig. 15 is a schematic view of a first partial structure of the first supporting sheet and the second supporting sheet provided in this embodiment of the application, and the flexible support 220 may further include a second supporting sheet 223, where the second supporting sheet 223 is located on the non-display surface of the main body portion 211. The second support sheet 223 has a different structure from the first support sheet 222, for example, the second support sheet 223 has a straight structure and does not have an arc-shaped structure, and the second support sheet 223 may provide a flat support surface for the main body portion 211. The second support piece 223 may have the same structure as the first support piece 222, which facilitates processing.

It can be understood that, in order to realize that the flexible screen display module 210 is in the stretching and bending region, the flexible screen display module 210 can be continuously bent from the flat state to the bent state according to the bending shape, and then bent to the flat state from the bent state, it is obvious that the material capable of realizing the two state transitions is generally a flexible material, and the material is required to be in the stretching state, such as each layer of film material in the flexible screen display module 210, but if only the flexible material is provided, in the stretching and bending portion, one end of the flexible material cannot be pulled according to the predetermined bending track in the stretching and bending state. And the flexible screen display module 210 cannot be directly stressed in the stretched state, because it is easy to cause the flexible screen display module 210 to be damaged. Obviously, to achieve the flexible screen display module 210 to stretch and contract at the bending position according to a predetermined trajectory and ensure that the flexible screen display module 210 is not separately stressed, an attachment rigid structure needs to be added in the bending area, but if a general rigid structure is adopted, the repeated switching of flattening and bending cannot be achieved. In the embodiment of the present application, the structure of the first supporting sheet 222 is improved, so that the first supporting sheet 222 can be switched between the first bending state and the second bending state, and further, the flexible screen can be easily switched between the unfolding state and the folding state.

It should be noted that the structure of the first supporting sheet 222 is not limited to this, for example, the first supporting sheet 222 may be deformed in the width direction of the electronic device 20, so that the first supporting sheet 222 may be stretched during the movement of the outer surface of the shaft 500, thereby ensuring that the first supporting sheet 222 can easily support the extension portion 212 in the telescopic bending area and can be telescopically bent during the movement along the outer surface of the shaft 500 without damage risk. It will be appreciated that if the rigid plate is provided directly on the non-display surface of the extension portion 212, the rigid plate may be broken and damaged due to insufficient tension when moving to the position of the shaft 500. If the rubber member or the spring-type elastic member is directly used, the supporting force for the extension portion 212 may be insufficient due to the excessive elasticity, and the flexible screen assembly 200 may be wrinkled or dented.

For example, as shown in fig. 16, fig. 16 is a schematic partial structural view of a first support sheet and a second support sheet provided in an embodiment of the present application. All or a part of the first support sheet 222 is provided with a plurality of meshes such as the meshes 2224 to improve the deformability of the first support sheet 222, for example, the first support sheet 222 may be etched with an acidic etching solution to etch a plurality of diamond-shaped meshes 2224 on the first support sheet 222, so that the first support sheet 222 has a diamond-shaped screen structure, and the diamond-shaped screen structure may provide the first support sheet 222 with stretchability in the width direction and/or the length direction of the electronic device 20. When the first supporting sheet 222 moves in the width direction of the electronic device 20, the first supporting sheet 222 receives the pressing force applied by the shaft 500 and the pulling force applied in the width direction of the electronic device 20, and may deform under the pressing force and the pulling force.

Mesh 2224 may be regular in shape, such as a diamond configuration, a rectangular configuration, etc., and mesh 2224 may also be irregular in shape. For example, the mesh openings 2224 of the present embodiment are formed in a diamond-shaped structure, such that all or a portion of the first support sheet 222 can form a diamond-shaped mesh structure, and the first support sheet 222 having the diamond-shaped mesh structure has the advantages of excellent flexibility, great advantage in ensuring the flatness of the flexible screen assembly module, and long bending life.

Wherein, when the size of the first support sheet 222 is equal to that of the expanded portion 212, the first support sheets 222 may each be processed into a diamond-shaped wire mesh structure; when the size of the first support sheet 222 is larger than that of the extension portion 212, the portion of the first support sheet 222 on the non-display surface of the extension portion 212 may be processed into a diamond-shaped screen structure, and the other portion of the first support sheet 222 is a flat rigid sheet structure, and is not required to be etched by using an etching solution, for example, the portion of the first support sheet 222 on the non-display surface of the main body portion 211. It is understood that the first support sheet 222 may include a first section and a second section, wherein the first section is disposed on the non-display surface of the main body portion 211, the first section is of a complete rigid sheet structure and has a mesh-free design, the second section is disposed on the non-display surface of the expansion portion 212, the second section is provided with a plurality of mesh holes 320, and the mesh holes 320 are of a diamond-shaped structure, such that the second section forms a diamond-shaped wire mesh structure. In the movement process of the first supporting sheet 222, the first supporting sheet 222 which is mainly located on the non-display surface of the expansion portion 212 is partially stressed, and only a part of the first supporting sheet 222 is processed into a diamond-shaped silk screen structure, so that on one hand, the deformability of the first supporting sheet 222 is ensured, on the other hand, the supporting strength of the whole first supporting sheet 222 can be ensured, and the difficulty and the cost of manufacturing can be reduced.

Referring to fig. 17, fig. 17 is a schematic diagram illustrating a second structure of the flexible panel assembly in the electronic device shown in fig. 7, the flexible panel assembly 200 may further include a protection layer such as a protection layer 224, and the protection layer 224 may be a PI (polyimide film) film. Of course, the protection layer 224 may also be a film structure made of other materials, such as a PET (Polyethylene terephthalate) film, a PE (Polyethylene) film, and the like. The first support sheet 222 is sandwiched between two protective layers 224, and the protective layers 224 cover the meshes 2224 to close the meshes 2224, so that an object (such as an adhesive of double-sided tape, glue, or the like) provided on the first support sheet 222 does not penetrate into other components through the meshes 2224. For example, the first support sheet 222 may include a first side and a second side that are oppositely disposed, the first side being a side near the non-display side of the flexible screen assembly 200, and the second side being a side away from the flexible screen assembly 200. The first side face is provided with a first protection layer 2241, and the first protection layer 2241 covers the meshes 2224 to close the meshes 2224 from the first side face to the second side face; the second side surface is provided with a second protection layer 2242, and the second protection layer 2242 is covered on the mesh openings 2224 to close the mesh openings 2224 from the second side surface toward the first side surface, so that an object (such as a double-sided tape, glue, and the like) disposed on the first support sheet 222 (including the first side surface and the second side surface) does not penetrate into the flexible screen assembly 200, or the middle frame, or the sliding member through the mesh openings 2224.

This application embodiment can not only increase tensile strength through setting up tensile first supporting sheet 222, but also can reduce flexible screen assembly 200's destruction risk, extension flexible screen assembly 200's life.

With continued reference to fig. 7, the shaft 500 may be a cylindrical structure, and the outer surface of the shaft 500 may be further provided with a first limit structure, such as a first limit structure, which may be an annular structure disposed around the periphery of the outer surface of the shaft 500. The quantity of first limit structure can be a plurality of, and a plurality of first limit structure intervals set up, and first limit structure's quantity also can be one. The first limit 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, or may be a groove structure disposed on the outer surface of the shaft 500, or when the first limit structure is plural, a part of the first limit structure may be the protruding structure, and another part of the first limit structure may be the groove structure. 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 has an arc structure, and a part of the surface has a square structure.

The soft rubber connecting band 221 is provided with a second limiting structure, the second limiting structure is arranged on one side of the soft rubber connecting band 221 far away from the extension part 212, and the second limiting structure can be matched with the first limiting structure. Such as: when first limit structure is the protrusion structure, the second limit structure can be groove structure, and first limit structure can hold in second limit structure this moment to be connected with second limit structure interference fit, make flexible glue connecting band 221 move according to the motion trail of predetermineeing (for example, do linear motion along the direction that is on a parallel with casing subassembly 100) under first limit structure and second limit structure's limiting displacement, and then make extension 212 move to casing subassembly 100 outside or casing subassembly 100 inside according to the motion trail of predetermineeing. For another example: when the first limiting structure is a groove structure, the second limiting structure can be a convex structure, and the second limiting structure can be accommodated in the first limiting structure and is connected with the groove wall of the first limiting structure in an interference fit manner. Also for example: when the number of the first limiting structures is multiple, a part of the first limiting structures are protruding structures, and a part of the first limiting structures are groove structures, a plurality of second limiting structures can be correspondingly arranged on the outer surface of the soft rubber connecting belt 221, wherein a part of the second limiting structures are matched with the protruding structures, and a part of the second limiting structures are matched with the groove structures. It can be understood that the first limit structure and the second limit structure are matched in shape and size and abut against each other, so as to limit the movement path of the soft rubber connecting belt 221.

For example, referring to FIGS. 7 and 18, FIG. 18 is a schematic cross-sectional view of the flexible screen assembly of FIG. 9 taken along line P4-P4. The first stopper structure includes a stopper groove 510, the stopper groove 510 is disposed around the outer surface of the shaft 500, and the groove width of the stopper groove 510 is gradually narrowed from the outer surface of the shaft 500 toward 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 rubber connecting band 221 and protrudes out of the surface of the soft rubber connecting band 221, the outer surface of the soft rubber connecting band 221 refers to a surface far away from the flexible screen assembly 200, and the inner surface of the soft rubber connecting band 221 refers to a surface connected to the non-display surface of the flexible screen assembly 200. Wherein, the material of spacing arch 2211 is the same with the material of flexible glue connecting band 221, for example be rubber, and the width of spacing arch 2211 widens gradually from the internal surface of flexible glue connecting band 221 towards the surface direction of flexible glue connecting band 221, make the shape of spacing arch 2211 can match with the shape of spacing recess 510, spacing arch 2211 can be embedded into spacing recess 510, and spacing arch 2211 can pass through the movement track of spacing recess 510 restriction flexible screen assembly 200, make extension 212 move to in casing assembly 100 or outside casing assembly 100 according to predetermineeing the orbit. Spacing arch 2211 is connected with spacing recess 510 interference fit, for example, the size of spacing arch 2211 slightly is greater than the size of spacing recess 510, when making in spacing arch 2211 installs spacing recess 510, the surface of spacing arch 2211 extrudes each other with the cell wall of spacing recess 510, with the butt fastness that increases spacing recess 510 and spacing arch 2211, can also increase the coefficient of friction between axle 500 and the flexible glue connecting band 221, form effective friction district between axle 500 and flexible glue connecting band 221.

It can be understood that if the friction coefficient between the shaft 500 and the soft adhesive connecting band 221 is too small, the soft adhesive connecting band 221 may slip during the movement of the shaft 500, and the expansion and storage of the expansion portion 212 may be unsmooth. According to the embodiment of the application, the soft rubber connecting belt 221 can not easily slide through the limiting groove 510 and the limiting protrusion 2211, and the display reliability of the flexible screen assembly 200 is further ensured. 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.

This application embodiment is through mutually supporting of first limit structure and second limit structure for flexible screen subassembly 200 can expand outside casing subassembly 100 or accomodate in casing subassembly 100 according to predetermineeing the motion trajectory, compares in relevant art, and this application embodiment can make flexible screen subassembly 200's expansion in-process not take place the skew, and then makes flexible screen subassembly 200 not take place to pull at the length direction of electronic equipment 20, further protects flexible screen subassembly 200 not damaged.

Fig. 19 is a schematic structural diagram of a first sliding member and a second sliding member provided in an embodiment of the present application, which is shown in fig. 7 and 19. The electronic device 20 may further include a first slider 710 and a second slider 720, for example, the first slider 710 may be disposed on the soft rubber connecting band 221 and located on the main body portion 310, and the second slider 720 may be disposed on the soft rubber connecting band 221 and located on the expansion portion 212. The first slider 710 and the second slider 720 are both slidably connected to the soft rubber connecting band 221, and the first slider 710 and the second slider 720 are both disposed at an interval from the shaft 500, and both the first slider 710 and the second slider 720 can slide relative to the soft rubber connecting band 221 along the surface of the soft rubber connecting band 221, so that the extension portion 212 can be unfolded outside the housing assembly 100 or be received inside the housing assembly 100 according to the preset movement track.

In the initial state, the first slider 710 is located at the first position (as shown in fig. 7), and the second slider 720 is located at the second position (as shown in fig. 7) of the soft adhesive connecting band 221. When the expansion part 212 moves in the direction out of the housing assembly 100, the first slider 710 and the second slider 720 both move in the direction close to the shaft 500, so that the first slider 710 is located at the third position (as shown in fig. 19), and the second slider 720 is located at the fourth position (as shown in fig. 19), so that the expansion part 212 located outside the housing assembly 100 can be slidably spread along the surface of the first slider 710, and the expansion part 212 located inside the housing assembly 100 can be slid along the surface of the second slider 720 to the surface of the shaft 500. When the expansion portion 212 moves in the direction inside the housing assembly 100, the first slider 710 and the second slider 720 both move in the direction away from the shaft 500, so that the expansion portion 212 located outside the housing assembly 100 can slide along the surface of the first slider 710 to the surface of the shaft 500, and the expansion portion 212 located inside the housing assembly 100 can slide along the second slider 720 to the inside of the housing assembly 100.

It is understood that the first sliding member 710 can limit the movement of the expansion portion 212 gradually winding around the outer surface of the shaft 500 (or winding around the outer surface of the shaft 500), and the second sliding member 720 can limit the movement of the expansion portion 212 gradually winding around the outer surface of the shaft 500 (or winding around the outer surface of the shaft 500), so as to limit the movement track of the whole expansion portion 212, so that the expansion portion 212 is gradually extended out of the housing assembly 100 according to the first preset movement track (or gradually retracted into the housing assembly 100 according to the second preset movement track).

As shown in fig. 20, fig. 20 is a schematic cross-sectional structure view of the flexible screen assembly and the shaft shown in fig. 9 along the direction P5-P5, each of the first sliding member 710 and the second sliding member 720 is provided with a sliding portion such as a sliding portion 730, and the size and shape of the sliding portion 730 are matched with the size and shape of the second limit structure on the soft adhesive connecting band 221. For example, when the second position-limiting structure is a groove structure, the sliding part 730 can be a protrusion structure; when the second position-limiting structure is a protrusion structure, the sliding portion 730 may be a groove structure.

The soft adhesive connecting band 221 is provided with a limiting portion for limiting the sliding distance between the first slider 710 and the second slider 720. For example, the soft rubber connecting band 221 is provided with a first limiting portion and a second limiting portion, the first limiting portion is located between the first sliding member 710 and the shaft 500, and the first limiting portion is used for limiting the sliding distance of the first sliding member 710 so as to prevent the first sliding member 710 from sliding excessively and abutting against the shaft 500; the second position-limiting portion is located between the second slider 720 and the shaft 500, and the second position-limiting portion is used for limiting the sliding distance of the second slider 720 so as to prevent the second slider 720 from sliding excessively and abutting against the shaft 500. The limiting part can be a stop block, a limiting screw and other parts which can be used as limiting barriers.

In some embodiments, the flexible glue connection belt 221 may be provided with a plurality of retractable stoppers, the retractable stoppers are disposed at different positions of the flexible glue connection belt 221 at intervals, and the electronic device 20 may control the retractable stoppers to extend out of the surface of the flexible glue connection belt 221 or retract into the interior of the flexible glue connection belt 221. The user can select the expansion size of the expansion part 212, for example, select to expand 20%, expand 50%, or expand 100%, and the electronic device 20 controls the corresponding telescopic stopper to extend out of the surface of the soft rubber connecting band 221 according to the expansion size selected by the user, so as to prevent the soft rubber connecting band 221 from continuing to move, and further control the expansion size of the expansion part 212. Compared with a winding drum type flexible screen in the related art, the expansion size of the display screen can be freely selected by a user according to the requirement of the user, and the display screen is more intelligent and humanized.

It should be noted that the structure of the first sliding member 710 is not limited thereto, for example, when the size of the soft rubber connection band 221 is equal to that of the extension portion 212, the main body portion 310 is not provided with the soft rubber connection band. The first sliding member 710 may include a sliding rail structure and a sliding structure capable of sliding along the sliding rail structure, and the first sliding member 710 may be made of a rigid material, such as wear-resistant and relatively rigid steel or a metal material. The outer surface of the slide rail structure is flush with the outer surface of the soft rubber connecting band 221, and a protrusion or a groove which is the same as the second limiting structure in structure is arranged on the slide rail structure, so that the slide structure can slide to the soft rubber connecting band 221 from the slide rail structure.

It should be noted that, when the first supporting sheet 222 is a rigid sheet with a mesh 2224 structure, the friction coefficient of the second protection layer 2242 is relatively small, so that the first sliding member 710 and the second sliding member 720 can directly slide along the surface of the second protection layer 2242, and the friction force on the second protection layer 2242 during the sliding process of the first sliding member 710 and the second sliding member 720 can also be reduced, thereby reducing the wear of the second protection layer 2242.

As shown in fig. 21 and 22, fig. 21 is a schematic structural diagram of the center shaft of the electronic device shown in fig. 2, and fig. 22 is a schematic structural diagram of the center shaft and the driving motor of the electronic device shown in fig. 2. The electronic device 20 may further include a driving motor 600, the driving motor 600 is connected to the shaft 500, and the driving motor 600 may drive the shaft 500 to rotate, so as to drive the soft adhesive connecting band 221 to move toward the direction outside the casing assembly 100 or inside the casing assembly 100. For example, the shaft 500 is provided with a through hole 520, a plurality of locking grooves 521 are formed on a wall of the through hole 520, an output shaft 610 of the driving motor 600 is provided with a plurality of locking teeth 611, the locking teeth 611 can be engaged with the locking grooves 521 to connect the driving motor 600 and the shaft 500, and the driving shaft is driven by the driving motor 600 to rotate, so as to drive the shaft 500 to rotate around the driving motor 600. It can be understood that the driving motor 600 and the shaft 500 may jointly form a belt wheel type motor device, and the shaft 500 rotates around the driving motor 600, so that the embodiment of the present application may save the occupied space of the driving motor 600 for the electronic device 20 compared to disposing the driving motor 600 outside the shaft 500. Of course, it is also possible to arrange the driving motor 600 outside the shaft 500 and to arrange a fixing member inside the shaft 500, around which the driving motor 600 drives the shaft 500 to rotate.

When the driving shaft 500 is driven by the driving motor 600 to rotate clockwise, the soft rubber connecting band 221 is driven by the shaft 500 to move around the outer surface of the shaft 500 towards the direction outside the shell assembly 100, so that the extension part 212 is gradually unfolded outside the shell assembly 100; when the driving shaft 500 of the driving motor 600 rotates counterclockwise, the soft rubber connecting band 221 is driven by the shaft 500 to move around the outer surface of the shaft 500 toward the inside of the housing assembly 100, so that the expansion part 212 is gradually recovered to the inside of the housing assembly 100. The electronic device 20 can also control the rotation time of the shaft 500 by controlling the working time of the driving motor 600, and further control the movement distance of the extension portion 212, so that the size of the extension portion 212 expanded outside the housing assembly 100 can be adjusted, the playing interest is higher, and the user experience is improved.
