Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, in particular to an electronic device. BACKGROUND

[0002] A scrollable / foldable screen electronic device adopts a display screen capable of being bent, and the display screen can be freely slid in or out like a scroll, so it is called a scrollable / foldable screen electronic device. According to the use mode of the scrollable / foldable screen electronic device, it can also be called a push-pull device. For example, when a large screen is needed, the display screen of the electronic device can be pulled outwards, so that the display screen can be expanded from the size of a mobile phone to the size of a tablet computer, providing users with larger screen space and better use experience.

[0003] However, in the process of pushing and pulling the display screen outwards or inwards, the display screen is prone to appear not to fit, hollow or virtual position at the bending part, which seriously affects the user experience. SUMMARY

[0004] To solve the above problems, the embodiments of the present application provide an electronic device.

[0005] In a first aspect, the embodiments of the present application provide an electronic device, comprising: a scrollable / foldable screen, the scrollable / foldable screen comprising a bending area; a middle frame, the scrollable / foldable screen being laid on the middle frame, the middle frame being capable of moving along the width direction of the electronic device relative to one end to the other end; when the one end of the middle frame moves towards or away from the other end, at least part of the bending area slides around the one end of the middle frame and changes from a bending state to a flat state; a support member located between the bending area and the one end of the middle frame, used to support the bending area during the movement of the bending area to the flat state; the support member comprises a first support part and a second support part, the surface of the first support part is attached to the one end of the middle frame, the surface of the second support part is attached to the bending area, and the bending area slides relative to the surface of the second support part; wherein the deformation ability of the first support part is greater than that of the second support part.

[0006] Based on the above scheme, a soft and hard combined support member is arranged between the bending area of the scrollable / foldable screen and the middle frame, wherein the harder second support part can provide a smooth surface for the bending area to slide on, and the softer first support part is easy to deform under stress to generate a counter supporting force on the bending area, thereby providing effective support to the bending area, so that the bending area is not prone to problems such as hollowing.

[0007] In some possible implementation ways of the above first aspect, the elastic modulus of the material of the first support part is greater than that of the material of the second support part.

[0008] It can be understood that the elastic modulus (Young's modulus) can be used to describe the ability of the material to resist deformation in the elastic deformation stage, and therefore the material forming the first support part and the second support part can be selected according to the elastic modulus of the material.

[0009] In some possible implementation ways of the first aspect, the material of the first support part or the second support part includes at least one of plastic, rubber, and thermosetting resin.

[0010] In some possible implementation ways of the first aspect, the first support part and the second support part are in an integrated structure. For example, the first support part and the second support part can be formed into an integrated structure through a two-color injection molding process.

[0011] In some possible implementation ways of the first aspect, the rollable screen further includes a non-rollable area connected to the rollable area along the width direction, and the non-rollable area is fixed to one side of the middle frame along the thickness direction of the electronic device.

[0012] In some possible implementation ways of the first aspect, the electronic device is a push-pull device, one end of the middle frame moves towards the other end, so that the electronic device is in a first push-pull state, and one end of the middle frame moves away from the other end, so that the electronic device is in a second push-pull state; the width of the electronic device in the first push-pull state is smaller than the width of the electronic device in the second push-pull state.

[0013] In some possible implementation ways of the first aspect, when the electronic device is in the first push-pull state, the rollable area includes a bending part and an extension part, wherein the bending part is connected to the non-rollable area, and the extension part is located on both sides of the middle frame along the thickness direction.

[0014] In some possible implementation ways of the first aspect, when one end of the middle frame moves away from the other end, the bending part slides around one end of the middle frame, changes from the rollable state to the flat state, and the extension part slides around one end of the middle frame, changes from the flat state to the rollable state.

[0015] In some possible implementation ways of the first aspect, the surface of the first support part adhered to the middle frame is in a circular arc shape, and the interface between the first support part and the second support part is in a circular arc interface line, the first plane is parallel to the thickness direction; and one end of the circular arc interface line is aligned with the connection between the bending part and the non-rollable area, and the other end of the circular arc interface line is aligned with the connection between the bending part and the extension part.

[0016] In some possible implementation ways of the first aspect, the support part is in a "C" shape, the second support part is in a crescent shape, the first support part includes two sub-support parts, and the two sub-support parts are symmetrically arranged at two ends of the crescent shape relative to the first axis; the first axis is parallel to the width direction of the electronic device.

[0017] In some possible implementation manners of the first aspect, the thickness of the sub-support portion in the thickness direction gradually increases along a direction from one end of the middle frame to the other end.

[0018] It can be understood that the connection between the bending portion and the non-bending area, and the connection between the bending portion and the extension portion are more likely to have a hollow phenomenon. Therefore, the thickness of the sub-support portion near the connection between the bending portion and the non-bending area is greater, and the thickness of the sub-support portion near the connection between the bending portion and the extension portion is greater, so as to provide stronger support force for the rollable screen.

[0034] Illustrative embodiments of the present application include, but are not limited to, an electronic device.

[0035] It should be noted that the electronic device of the embodiments of the present application includes, but is not limited to, a mobile station (MS), a mobile terminal (MT), etc. For example, the electronic device can be a mobile phone, a smart television, a wearable device, a tablet computer (Pad), a desktop computer, a laptop computer, a virtual reality (VR) device, an augmented reality (AR) device, a terminal in industrial control, a terminal in self driving, a terminal in remote medical surgery, a terminal in smart grid, a terminal in transportation safety, a terminal in smart city, a terminal in smart home, etc. The embodiments of the present application do not limit the specific form of the electronic device.

[0036] In addition, the electronic device of the embodiments of the present application is a push-pull device, for example, the display screen of the electronic device can be pushed inwards or pulled outwards, so that the display screen presents different screen sizes. It can be understood that during the push-pull process, the display screen is retracted and expanded like a reel, therefore, the electronic device is also commonly referred to as a reel-type electronic device, or a rollable screen electronic device.

[0037] In order to make the objects, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0038] FIGS. 1A-1D Some embodiments of the electronic device 1 in different use states and at different angles are shown. Among them, FIG. 1A and FIG. 1C respectively show the perspective view and the front view of the electronic device 1 in the first push-pull state, FIG. 1B and FIG. 1D respectively show the perspective view and the front view of the electronic device 1 in the second push-pull state.

[0039] It should be noted that in the drawings of the present application, the X-axis direction can be the width direction of the electronic device 1, for example, the positive direction of the X-axis can be from the left side of the electronic device 1 to the right side; the Y-axis direction can be the length direction of the electronic device 1, for example, the positive direction of the Y-axis can be from the bottom of the electronic device 1 to the top; the Z-axis direction can be the thickness direction of the electronic device 1, for example, the positive direction of the Z-axis can be from the back of the electronic device 1 to the front. The front and the back are two side surfaces of the electronic device 1 arranged opposite along the Z-axis direction, wherein the front can represent the surface facing the user when the user holds the electronic device 1, and the back can represent the surface away from the user when the user holds the electronic device 1. Among them, the X-axis direction, the Y-axis direction and the Z-axis direction can be perpendicular to each other.

[0040] As shown in FIGS. 1A-1D , the electronic device 1 comprises a rollable screen 10, a housing 20 and a push-pull mechanism (not shown in the figure), wherein the rollable screen 10 is laid on the housing 20, and an inner cavity of the electronic device 1 is formed between the rollable screen 10 and the housing 20, which is used to place various electronic devices (such as mainboards, sensors, microphones) of the electronic device 1 and the push-pull mechanism.

[0041] Under the action of the push-pull mechanism, the rollable screen 10 can be unfolded towards the negative direction of the X-axis, or rolled up towards the positive direction of the X-axis, and the housing 20 can be contracted in the X-axis direction, so that the electronic device 1 can be switched between the first push-pull state and the second push-pull state.

[0042] As shown in FIG. 1A and FIG. 1B , the rollable screen 10 comprises a bending and rolling area 10-1 and a non-bending and rolling area 10-2 connected in the X-axis direction, wherein the non-bending and rolling area 10-2 is fixedly arranged on the front of the electronic device 1, and the bending and rolling area 10-1 can be rolled up from the front of the electronic device 1 to the back of the electronic device 1 counterclockwise around the Y-axis, or unfolded from the back of the electronic device 1 to the front of the electronic device 1 clockwise around the Y-axis.

[0043] It can be understood that, in FIG. 1A In the first push-pull state shown in FIG. 1A, the bending area 10-1 is located at the back of the electronic device 1, at this time, the electronic device 1 can also display a picture through the bending area 10-1 at the back. It should be noted that in other embodiments, the bending area 10-1 of the bending slide screen 10 can also be rolled into the inner cavity of the electronic device 1, that is, in the first push-pull state, the back of the electronic device 1 can not display a picture, which is not limited in the present application.

[0044] In the embodiments of the present application, the shell 20 includes a middle frame and an outer shell, wherein the middle frame is a main structural member for carrying various electronic devices and the bending slide screen 10, and part of the structure of the middle frame cooperates with the push-pull mechanism to enable the middle frame to drive the bending slide screen 10 to realize the bending movement of the bending slide screen 10 under the action of the push-pull mechanism. Generally, the middle frame extends along the X-axis direction and the Y-axis direction, and has a certain thickness in the Z-axis direction. It can be understood that the specific structure and form of the middle frame are designed according to the spatial layout of the actual electronic device 1, which is not limited in the present application, and the structure and form of the middle frame shown in the figures are only examples. The outer shell serves as a protective shell of the electronic device 1, which can protect various electronic devices from being damaged and improve the appearance of the electronic device 1. In some embodiments, the outer shell and the middle frame can be an integrated structure or a split structure.

[0045] As described above, under the action of the push-pull mechanism, the shell 20 can be stretched and contracted in the X-axis direction, and the bending slide screen 10 can be unfolded along the X-axis direction or rolled around the Y-axis. In this way, the electronic device 1 is in different push-pull states, and different sizes of display areas are presented on the front through the bending slide screen 10 to meet the user's use demand for different sizes of display areas.

[0046] For example, FIG. 1C As shown in FIG. 1A, the electronic device 1 is in the first push-pull state, at this time, the shell 20 is in a completely contracted state in the X-axis direction, the bending slide screen 10 (for example, the non-bending area 10-2) presents a display picture A on the front of the electronic device 1, and the bending area 10-1 is bent to the back of the electronic device 1 at the left side of the electronic device 1.

[0047] When the electronic device 1 changes from the first push-pull state to the second push-pull state, the shell 20 gradually expands towards the negative direction of the X-axis, at the same time, the bending area 10-1 of the bending slide screen 10 also gradually rolls around the left side of the electronic device 1 from the back or the inside of the electronic device 1 to the front of the electronic device 1, and finally the bending slide screen 10 is completely unfolded (i.e. the bending area 10-1 and the non-bending area 10-2) to present a display picture B as shown in FIG. 1B on the front of the electronic device 1. FIG. 1D As can be seen, the width of the display picture B is greater than that of the display picture A, which can meet the user's use demand for a large screen.

[0048] It can be understood that, under the action of the push-pull mechanism, the electronic device 1 can also be changed from the second push-pull state shown in FIG. 1B / FIG. 1D to the first push-pull state shown in FIG. 1A / FIG. 1C . The specific process will not be repeated here.

[0049] At present, when the electronic device 1 is switched between the first push-pull state and the second push-pull state, that is, the rollable screen 10 is bent and rolled to the back of the electronic device 1, or is unrolled around to the front of the electronic device 1, the bending area 10-1 of the rollable screen 10 is prone to the phenomenon of not fitting, hollowing, or virtual position, etc. at the bending part (for example, the area in the dashed line frame shown in FIG. 1D ). For example, FIG. 1E shows a cross-sectional view of the area in the dashed line frame in FIG. 1D in the C-C direction. As shown in FIG. 1E , due to the self-tension of the rollable screen 10, insufficient pulling force of the push-pull mechanism, etc., the bending part of the bending area 10-1 and the middle frame 21 have the problem of hollowing and not fitting. This seriously affects the user experience.

[0050] Based on this, the embodiments of the present application propose an elastic support scheme for the rollable screen 10. A soft and hard combined support member is arranged between the bending area 10-1 of the rollable screen 10 and the middle frame 21, so as to support the bending area 10-1, so as to solve the above problems of not fitting, hollowing, or virtual position, etc.

[0051] The technical solutions of the present application will be described in detail below with reference to the drawings.

[0052] FIG. 2 shows a partial structure diagram of the electronic device 1 in some embodiments of the present application. It can be understood that FIG. 2 the partial structure of the electronic device 1 shown in FIG. 1B may be a partial structure diagram of the position shown in the circular dashed line frame in

[0053] In some embodiments, as shown in FIG. 2 , a support member 30 is arranged between the bending area 10-1 and the middle frame 21. The support member 30 can support the bending area 10-1. For example, when the bending area 10-1 slides in the direction shown by the dashed arrow in FIG. 2 , the support member 30 can provide a support force for the bending area 10-1.

[0054] In some embodiments, the support 30 comprises a first support portion 310 and a second support portion 320. The surface of the first support portion 310 is attached to one end of the middle frame 21, and the surface of the second support portion 320 is attached to the bending area 10-1, and the bending area 10-1 slides relative to the surface of the second support portion 320. For example, the bending area 10-1 slides relative to the surface of the second support portion 320 in the direction indicated by the dashed arrow. FIG. 2 The surface of the second support portion 320 is attached to the bending area 10-1, and the bending area 10-1 slides relative to the surface of the second support portion 320.

[0055] In addition, the deformation ability of the first support portion 310 is greater than the deformation ability of the second support portion 320. It can be understood that the first support portion 310 is more likely to deform than the second support portion 320, that is, the first support portion 310 is softer, and the second support portion 320 is harder. Thus, the harder second support portion 320 can provide a smoother surface for the bending area 10-1 to slide on, and the softer first support portion 310 is easily deformed under stress to generate a reverse support force on the bending area 10-1, thereby providing effective support to the bending area 10-1, so that the bending area 10-1 is not prone to problems such as hollowing.

[0056] For ease of understanding, the following will be combined with FIG. 3 The stress condition of the support 30 is analyzed. First, as FIG. 3 indicated, the bending area 10-1 of the roll-sliding screen 10 can include a bending portion 10-11 and an extension portion 10-12, wherein the bending portion 10-11 is the part of the bending area 10-1 that is in a bending state, and the extension portion 10-12 is the part of the bending area 10-1 that is in a flattened state. Secondly, it can be understood that the roll-sliding screen 10 located on both sides of the middle frame 21 along the Z-axis direction will be subjected to a pulling force F1 and a pulling force F2, respectively, wherein the pulling force F1 is a fixed pulling force from the non-bending area 10-2, and the pulling force F2 is the force applied by the push-pull mechanism to drive the roll-sliding screen 10 to slide in the direction indicated by the dashed arrow. FIG. 2 Thus, the bending portion 10-11 will compress the support 30 under the action of the pulling force F1 and the pulling force F2, so that the softer first support portion 310 of the support 30 deforms to generate a reverse support force F3, thereby providing effective support to the bending portion 10-11 and preventing the roll-sliding screen 10 from being prone to local hollowing.

[0057] In some embodiments, the elastic modulus of the material of the first support portion 310 is greater than the elastic modulus of the material of the second support portion 320. In this way, the deformation ability of the first support portion 310 is greater than the deformation ability of the second support portion 320. It can be understood that the elastic modulus (Young's modulus) can be used to describe the ability of a material to resist deformation in the elastic deformation stage, and therefore the materials forming the first support portion 310 and the second support portion 320 can be selected according to the elastic modulus of the materials.

[0058] In other embodiments, the material forming the first support portion 310 and the second support portion 320 can also be selected according to a strength index parameter or a hardness index parameter of the material, such as yield strength, compressive strength, etc., so that the deformation capability of the first support portion 310 is greater than that of the second support portion 320. For example, the yield strength, compressive strength, or hardness of the material of the first support portion 310 can be less than that of the material of the second support portion 320.

[0059] For example, the material of the first support portion 310 or the second support portion 320 includes at least one of plastic, rubber, and thermosetting resin. Specifically, the material of the second support portion 320 can include polyoxymethylene (POM), which is a high-performance engineering plastic with excellent mechanical properties, wear resistance, fatigue resistance, and chemical resistance. The material of the first support portion 310 can include thermoplastic polyester elastomer (TPEE), which has good elasticity and flexibility.

[0060] In some embodiments, the first support portion 310 and the second support portion 320 are integrated into a one-piece structure. For example, the first support portion 310 and the second support portion 320 can be formed into a one-piece structure by a two-color injection molding process.

[0061] Alternatively, in other embodiments, the first support portion 310 and the second support portion 320 can be bonded by an adhesive (e.g., hot melt adhesive).

[0062] In some embodiments, the surface of the first support portion 310 and the middle frame 21 are bonded by an adhesive (e.g., hot melt adhesive).

[0063] It should be noted that, due to the various forms of the middle frame 21 and the roll-to-slide screen 10, the specific structure of the support 30 can be designed according to the internal space of the specific electronic device 1, the form of the roll-to-slide screen 10, and the structure of the middle frame 21, for example, FIG. 2 and FIG. 3 As shown in FIGS. 1A and 1B, the support 30 can have a “C” shape, but the specific structure of the support 30 is not limited in the present application.

[0064] Hereinafter, the structure of the support 30 will be described exemplarily based on two different forms of the roll-to-slide screen 10 and the structure of the middle frame 21.

[0065] FIG. 4 FIGS. 1A and 1B show a schematic diagram of the partial structure of the electronic device 1 in some embodiments. FIG. 4 (b) of FIG. 1B corresponds to the first push-pull state of the electronic device 1, FIG. 4 (c) of FIG. 1B corresponds to the second push-pull state of the electronic device 1, and, for the convenience of understanding the movement of the roll-to-slide screen 10,FIG. 4 (a) and (d) in the figure illustrate the various partitions of the scrolling screen 10 in the first push-pull state and the second push-pull state, respectively.

[0066] like FIG. 4 As shown in (b) and (c), the scrollable screen 10 is laid on the middle frame 21. One end 21a of the middle frame 21 along the X-axis can move relative to the other end 21b along the X-axis. When one end 21a of the middle frame 21 moves toward the other end 21b, the electronic device 1 is in a first push-pull state; when one end 21a of the middle frame 21 moves away from the other end 21b, the electronic device 1 is in a second push-pull state. FIG. 4 As can be seen from (b) and (c), the width of the electronic device 1 in the first push-pull state is smaller than the width of the electronic device 1 in the second push-pull state. Furthermore, the non-bending region 10-2 is fixed to the side of the middle frame 21 facing the positive Z-axis direction.

[0067] like FIG. 4 As shown in (a) and (b), when the electronic device 1 is in the first push-pull state, the bending region 10-1 includes a bending part 10-11 and an extension part 10-12, wherein the extension part 10-12 and the non-bending region 10-2 are located on both sides of the middle frame 21 along the Z-axis direction, respectively.

[0068] When one end 21a of the middle frame 21 moves away from the other end 21b, the bending portion 10-11 of the bending region 10-1 slides around one end 21a of the middle frame 21, changing from a bent state to a flattened state. The extension portion 10-12 slides around one end 21a of the middle frame 21, changing from a flattened state to a bent state.

[0069] For example, from FIG. 4 (b) to FIG. 4 In the state shown in (c), one end 21a of the middle frame 21 moves away from the other end 21b. At this time, FIG. 4 The bending section 10-11 shown in (a) is in accordance with FIG. 4 As shown by the dashed arrow in (b), the bending part 10-11 slides around one end 21a of the middle frame 21 to the side of the middle frame 21 facing the positive Z-axis, changing from a bent state to a flattened state. That is, the bending part 10-11 moves to the surface of the middle frame 21 facing the positive Z-axis. FIG. 4 The extension portion 10-12 shown in (a) slides from the middle frame 21 toward the negative Z-axis direction on one side of the middle frame 21 around one end 21a of the middle frame 21, changing from a flattened state to a rolled state.

[0070] like FIG. 4As shown in (c) and (d), when the electronic device 1 is in the second push-pull state, the bending region 10-1 includes a bending portion 10-11 and two extension portions 10-12, wherein the two extension portions 10-12 are located on both sides of the middle frame 21 along the Z-axis direction, and the extension portion 10-12 located on the side of the middle frame 21 facing the positive Z-axis direction is in the same plane as the non-bending region 10-2.

[0071] When one end 21a of the middle frame 21 moves toward the other end 21b, the bending part 10-11 slides around one end 21a of the middle frame 21, changing from a bent state to a flattened state. The extension part 10-12 located on the side of the middle frame 21 facing the positive Z-axis slides around one end 21a of the middle frame 21, changing from a flattened state to a bent state.

[0072] For example, from FIG. 4 (c) to FIG. 4 In the state shown in (b), one end 21a of the middle frame 21 moves toward the other end 21b. At this time, FIG. 4 The bending section 10-11 shown in (d) is in accordance with FIG. 5 As shown by the dashed arrow in (c), the middle frame 21 slides around one end 21a to the side of the middle frame 21 facing the negative Z-axis, becoming the extension 10-12, changing from a bent state to a flattened state. That is, the bent part 10-11 moves to the surface of the middle frame 21 facing the negative Z-axis. FIG. 5 The extension 10-12 shown in the middle (d) is located on the side of the middle frame 21 facing the positive direction of the Z axis. It slides around one end 21a of the middle frame 21 and changes from a flat state to a rolled state.

[0073] Understandable, such as FIG. 4 As shown in (c) and (d), the extension 10-12 located on the side of the middle frame 21 facing the positive Z-axis was originally in a flattened state. When one end 21a of the middle frame 21 moves towards the other end 21b, the extension 10-12 moves along... FIG. 5 The section shown in (c) slides in the direction indicated by the dashed arrow, becoming the curved section 10-11, that is, changing from a flattened state to a rolled state.

[0074] In this embodiment, one end 21a of the middle frame 21 has a protrusion, and correspondingly, the support member 30 is roughly C-shaped. Specifically, the structure of the support member 30 can be referred to... FIG. 5 .

[0075] like FIGS. 6A-6CAs shown, in some embodiments, the surface 310a of the first support portion 310 adhered to the middle frame 21 is in the shape of a circular arc, and the interface 320a between the first support portion 310 and the second support portion 320 is in the shape of a circular arc interface with the XZ plane (the first plane of the present application). The circular arc interface has one end M and another end N along the extension direction thereof. In combination with FIG. 6A As shown in (a) and (b) of FIG. 10, one end M of the circular arc interface is aligned with the connection between the bending portion 10-11 and the non-bending area 10-2, and the other end N of the circular arc interface is aligned with the connection between the bending portion 10-11 and the extension portion 10-12.

[0076] Referring back to FIG. 10, FIG. 6B In some embodiments, the second support portion 320 is in the shape of a crescent, and the first support portion 310 includes two sub-support portions 310-1 and 310-2, which are symmetrically arranged at two ends of the crescent with respect to the first axis parallel to the X-axis direction.

[0077] The two sub-support portions 310-1 and 310-2 are of the same structure. Taking the sub-support portion 310-1 as an example, the thickness of the sub-support portion 310-1 in the Z-axis direction gradually increases along the positive direction of the X-axis. It can be understood that the connection between the bending portion 10-11 and the non-bending area 10-2, and the connection between the bending portion 10-11 and the extension portion 10-12 are more prone to hollowing phenomenon. Therefore, the thickness of the sub-support portion 310-1 near the connection between the bending portion 10-11 and the non-bending area 10-2 is larger, and the thickness of the sub-support portion 310-2 near the connection between the bending portion 10-11 and the extension portion 10-12 is larger, so as to provide stronger support force for the roll screen 10.

[0078] Referring back to FIG. 10, FIG. 6C In this embodiment, the roll screen 10 only contacts the surface of the second support portion 320, and the surface of the second support portion 320 can be polished to improve the smoothness of the roll screen 10.

[0079] It should be noted that the present application does not limit the shape of the two sub-support portions of the first support portion 310 and the second support portion 320. FIG. 7 Several other possible examples are shown.

[0080] As FIG. 7As shown, in the XZ plane, the second support portion 320 is semi-circular, and the interface between the first support portion 310 and the second support portion 320 is a straight line with the boundary line of the XZ plane. In this example, the rollable screen 10 can contact the two sub-support portions 310-1 and 310-2. When the two sub-support portions 310-1 and 310-2 are compressed by the rollable screen 10, they can provide a reverse support force to the rollable screen 10, making it less prone to bulging.

[0081] like FIG. 7 As shown, in the XZ plane, the two sub-supports 310-1 and 310-2 and the second support 320 can also be fan-shaped. Alternatively, as... FIG. 7 As shown, the two sub-supports of the first support portion 310 and the second support portion 320 can also be other irregular structures, which are not limited in this application.

[0082] Furthermore, this application embodiment does not limit the number of sub-supports of the first support portion 310. Depending on the actual application scenario, the first support portion 310 can be disassembled into more or fewer sub-supports.

[0083] FIG. 4 A partial structural schematic diagram of electronic device 1 is shown in some other embodiments. FIG. 4 (a) in the diagram corresponds to the first push-pull state of electronic device 1. FIG. 7 (b) in the diagram corresponds to the second push-pull state of electronic device 1.

[0084] FIG. 7 The electronic device 1 shown is FIG. 7 The difference in the electronic device 1 shown lies in the structure of the mid-frame 21 and the shape of the rollable screen 10. For example, FIG. 7 The sliding screen 10 shown can be bent into a "U" shape. FIG. 7 The slide screen 10 shown can be bent into a "P" shape.

[0085] like FIG. 7 As shown, in this embodiment, the middle frame 21 includes a first structural member 21-1, a second structural member 21-2, and a third structural member 21-3. The rollable screen 10 is capable of bending around the first structural member 21-1 and rolling up to the gap between the second structural member 21-2 and the third structural member 21-3. The second structural member 21-2 and the third structural member 21-3 are capable of telescoping along the X-axis. It should be noted that this application does not limit the connection relationship between the first structural member 21-1, the second structural member 21-2, and the third structural member 21-3, and any one of these structural members can be a single integrated structure. For example, the first structural member 21-1 and the second structural member 21-2 can be a single integrated structure, or the structural members can be independent of each other.

[0086] In some embodiments, the first structural member 21-1 extends along the Y-axis and is rotatable about its own axis.

[0087] For example, from FIG. 7 Middle (a) to FIG. 8 In the state shown in (b), the second structural member 21-2 and the third structural member 21-3 are extended in the X-axis direction. At this time, the sliding screen 10 located between the second structural member 21-2 and the third structural member 21-3 is in accordance with... FIG. 8 As shown by the dashed arrow in (a), slide around the first structural member 21-1 to the side of the second structural member 21-2 facing the positive Z-axis. Alternatively, from... FIG. 8 (b) to FIG. 2 In the state shown in (a), the second structural member 21-2 and the third structural member 21-3 retract in the X-axis direction. At this time, the portion of the sliding screen 10 located on the side of the second structural member 21-2 facing the positive Z-axis direction... FIG. 4 As shown by the dashed arrow in (b), it slides around the first structural member 21-1 to the gap between the second structural member 21-2 and the third structural member 21-3.

[0088] It is understandable that there are also problems such as hollowness and non-fitting between the rollable screen 10 and the first structural component 21-1.

[0089] FIG. 9 A partial structural schematic diagram of the electronic device 1 after the addition of the support member 30 is shown.

[0090] like FIG. 1B As shown, in this embodiment, the support member 30 is arranged around the first structural member 21-1, and the first support part 310 is disposed in close contact with the first structural member 21-1. The second support part 320 is disposed around the first support part 310 and contacts the scrolling screen 10.

[0091] The first support portion 310 may include two sub-support portions 310-1 and 310-2. The two sub-support portions 310-1 and 310-2 have the same structure and are symmetrically arranged along an axis parallel to the X-axis. Taking the sub-support portion 310-1 as an example, the sub-support portion 310-1 may be crescent-shaped.

[0092] In addition, the second support portion 320 may also be crescent-shaped, and there may be two second support portions 320, which are symmetrically arranged along an axis parallel to the Z-axis.

[0093] It should be noted that, FIG. 9 The structure of the middle support 30 is only an example. In actual applications, sub-supports 310-1 and 310-2 can be set according to the locations where hollowness is likely to occur.

[0094] It is understood that the performance and materials of the first support part 310 and the second support part 320 can be referred to ​ Related embodiments will not be described in detail here.

[0095] The following is based on ​ Related embodiments, in conjunction with ​ The push-pull mechanism 40 in some embodiments of this application is described. (In conjunction with...) ​ As shown, the position of the push-pull mechanism 40 in some embodiments of this application can be indicated by a rectangular dashed box.

[0096] like ​ As shown, the push-pull mechanism 40 includes at least a first connecting block 410, a second connecting block 420, a fixed pulley 430, a rope 440 (e.g., a steel wire rope), and a motor (not shown). One end of the rope 440 is connected to the first connecting block 410, and the other end is connected to the second connecting block 420. Both the second connecting block 420 and the fixed pulley 430 are fixed components. Driven by the motor, the first connecting block 410 can move in the X-axis direction.

[0097] Furthermore, the first connecting block 410 and the second connecting block 420 are respectively connected to the middle frame 21. Thus, when the first connecting block 410 moves in the X-axis direction, it can drive one end 21a of the middle frame 21 to move toward or away from the other end 21b, and drive the sliding screen 10 to move in contact with the middle frame 21, and form a rolling shutter movement around one end 21a of the middle frame 21.
