Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] Roll-up / roll-up screen electronic devices use a bendable display screen that can slide in or out freely like a scroll, so they are called roll-up electronic devices or roll-up screen electronic devices. Depending on how the roll-up screen electronic device is used, 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 outward, 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 a larger screen space and a better user experience.

[0003] However, currently, when the display screen is pushed or pulled outward or inward, it is easy for the display screen to have non-fitting, hollowing or empty space at its bent part, which seriously affects the user experience. Summary of the invention

[0004] In order to solve the above problems, an embodiment of the present application provides an electronic device.

[0005] In the first aspect, an embodiment of the present application provides an electronic device, comprising: a rolling screen, the rolling screen including a rolling area; a middle frame, the rolling screen is laid on the middle frame, and one end of the middle frame along the width direction of the electronic device can move along the width direction relative to the other end; when one end of the middle frame moves toward or away from the other end, at least a part of the rolling area slides around one end of the middle frame and changes from a rolled state to a flattened state; a support member, located between the rolling area and one end of the middle frame, for supporting the rolling area during the movement of the rolling area to the flattened state; the support member comprises a first supporting portion and a second supporting portion, the surface of the first supporting portion is in contact with one end of the middle frame, the surface of the second supporting portion is in contact with the rolling area, and the rolling area slides relative to the surface of the second supporting portion; wherein the deformation capacity of the first supporting portion is greater than the deformation capacity of the second supporting portion.

[0006] Based on the above solution, a soft and hard combined support member is arranged between the bending area of ​​the rolling screen and the middle frame, wherein the harder second support portion can provide a smooth surface for the bending area to slide on the surface, and the softer first support portion is easily deformed under force to generate a reverse supporting force on the bending area, thereby being able to provide effective support for the bending area, making it less likely for the bending area to have problems such as hollowing.

[0007] In some possible implementations of the first aspect above, an elastic modulus of a material of the first support portion is greater than an elastic modulus of a material of the second support portion.

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

[0009] In some possible implementations of the first aspect above, a material of the first support portion or the second support portion includes at least one of plastic, rubber, and thermosetting resin.

[0010] In some possible implementations of the first aspect, the first support portion and the second support portion are an integrated structure. Exemplarily, the first support portion and the second support portion can be formed into an integrated structure by a two-color injection molding process.

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

[0012] In some possible implementations of the first aspect above, the electronic device is a push-pull device, one end of the middle frame moves toward 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 when it is in the first push-pull state is smaller than the width of the electronic device when it is in the second push-pull state.

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

[0014] In some possible implementations of the first aspect above, when one end of the middle frame moves away from the other end, the bending portion slides around one end of the middle frame, changing from a rolled state to a flattened state, and the extension portion slides around one end of the middle frame, changing from a flattened state to a rolled state.

[0015] In some possible implementations of the first aspect above, the surface on which the first support portion is bonded to the middle frame is in an arc shape, and the interface between the first support portion and the second support portion is an arc intersection line with the boundary line of the first plane, and the first plane is parallel to the thickness direction; and one end of the arc intersection line is aligned with the connection between the bending portion and the non-curling area, and the other end of the arc intersection line is aligned with the connection between the bending portion and the extension portion.

[0016] In some possible implementations of the first aspect above, the support member is C-shaped, and the second support portion is crescent-shaped. The first support portion includes two sub-support portions, and the two sub-support portions are symmetrically arranged at both ends of the crescent relative to the first axis; the first axis is parallel to the width direction of the electronic device.

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

[0018] It can be understood that the connection between the bending part and the non-bending area, and the connection between the bending part and the extension part are more prone to hollowing phenomenon. Therefore, the thickness of the sub-support part near the connection between the bending part and the non-bending area is larger, and the thickness of the sub-support part near the connection between the bending part and the extension part is larger, so as to provide stronger supporting force for the rolling sliding screen.

DETAILED DESCRIPTION

[0020] Illustrative embodiments of the present application include, but are not limited to, an electronic device.

[0021] It should be noted that the electronic devices in the embodiments of the present application include but are not limited to mobile stations (MS), mobile terminals (MT), etc. For example, the electronic devices may be mobile phones, smart TVs, wearable devices, tablet computers (Pad), desktop computers, laptop computers, virtual reality (VR) devices, augmented reality (AR) devices, terminals in industrial control, terminals in self-driving, terminals in remote medical surgery, terminals in smart grids, terminals in transportation safety, terminals in smart cities, terminals in smart homes, etc. The embodiments of the present application do not limit the specific form of the electronic devices.

[0022] In addition, the electronic device of the embodiment of the present application is a push-pull device, for example, the display screen of the electronic device can be pushed inward or pulled outward, so that the display screen presents different screen sizes. It can be understood that during the push-pull process, the display screen shrinks and expands like a scroll, so the electronic device is usually also called a scroll-type electronic device or a scroll-screen electronic device.

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0024] Figures 1A to 1D Schematic diagrams of electronic devices 1 in different usage states and at different angles in some embodiments are shown. Figure 1A and Figure 1CThe three-dimensional schematic diagram and the front schematic diagram of the electronic device 1 in the first push-pull state are respectively shown. Figure 1B and Figure 1D The three-dimensional schematic diagram and the front schematic diagram of the electronic device 1 in the second push-pull state are respectively shown.

[0025] It should be noted that in the various figures of the present application, the X-axis direction may be the width direction of the electronic device 1, and illustratively, the positive direction of the X-axis may be from the left side of the electronic device 1 to the right side; the Y-axis direction may be the length direction of the electronic device 1, and illustratively, the positive direction of the Y-axis may be from the bottom of the electronic device 1 to the top; the Z-axis direction may be the thickness direction of the electronic device 1, and illustratively, the positive direction of the Z-axis may be from the back side of the electronic device 1 to the front side. The front and back sides are two side surfaces of the electronic device 1 that are arranged opposite to each other along the Z-axis direction, wherein the front side may refer to the surface facing the user when the user holds the electronic device 1, and the back side may refer to the surface facing 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 may be perpendicular to each other.

[0026] like Figures 1A to 1D As shown, the electronic device 1 includes a rolling screen 10, a shell 20 and a push-pull mechanism (not shown in the figure), wherein the rolling screen 10 is laid on the shell 20, and an inner cavity of the electronic device 1 is formed between the rolling screen 10 and the shell 20, and the inner cavity is used to place various electronic devices (such as a motherboard, a sensor, a microphone) of the electronic device 1 and the push-pull mechanism.

[0027] Under the action of the push-pull mechanism, the rolling screen 10 can be unfolded in the negative direction of the X-axis, or rolled up in the positive direction of the X-axis, and the shell 20 can be contracted in the X-axis direction, so that the electronic device 1 can switch between the first push-pull state and the second push-pull state.

[0028] like Figure 1A and Figure 1B As shown, the rolling screen 10 includes a rolling area 10-1 and a non-rolling area 10-2 connected along the X-axis direction, wherein the non-rolling area 10-2 is fixed on the front of the electronic device 1, and the rolling area 10-1 can be rolled up counterclockwise around the Y-axis from the front of the electronic device 1 to the back of the electronic device 1, and can also be unfolded clockwise around the Y-axis from the back of the electronic device 1 to the front of the electronic device 1.

[0029] Understandably, Figure 1A In the first push-pull state shown, the rolled area 10-1 is located on the back of the electronic device 1. At this time, the electronic device 1 can also display the picture through the rolled area 10-1 on the back. It should be noted that in other embodiments, the rolled area 10-1 of the rolling screen 10 can also be rolled up to the inner cavity of the electronic device 1, that is, in the first push-pull state, the back of the electronic device 1 may not display the picture, and this application does not limit this.

[0030] In the embodiment of the present application, the shell 20 includes a middle frame and an outer shell, wherein the middle frame is the main structural member for carrying various electronic devices and the rolling screen 10, and the local structure of the middle frame cooperates with the push-pull mechanism so that under the action of the push-pull mechanism, the middle frame can drive the rolling screen 10 to realize the bending movement of the rolling screen 10. 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. This application does not limit this. The structure and form of the middle frame shown in the various figures are only examples. As a protective shell of the electronic device 1, the outer shell can protect various electronic devices from damage and enhance 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.

[0031] As mentioned above, under the action of the push-pull mechanism, the housing 20 can be extended and retracted in the X-axis direction, and the rolling screen 10 can be unfolded along the X-axis direction or rolled up around the Y-axis. In this way, the electronic device 1 is in different push-pull states, and the front of the electronic device 1 presents display areas of different sizes through the rolling screen 10, so as to meet the user's use requirements for display areas of different sizes.

[0032] For example, Figure 1C As shown, the electronic device 1 is in a first push-pull state, at which time the shell 20 is in a fully retracted state in the X-axis direction, the rolling screen 10 (for example, the non-rolling area 10-2) presents a display screen A on the front of the electronic device 1, and the rolling area 10-1 is rolled to the back of the electronic device 1 at the left side of the electronic device 1.

[0033] When the electronic device 1 changes from the first push-pull state to the second push-pull state, the housing 20 gradually stretches toward the negative direction of the X-axis. At the same time, the rolled area 10-1 of the rolling screen 10 also gradually rolls from the back or inside of the electronic device 1 to the front of the electronic device 1 on the left side of the electronic device 1. Finally, the rolling screen 10 is fully unfolded (that is, the rolled area 10-1 and the non-rolled area 10-2) and appears on the front of the electronic device 1 as shown in FIG. Figure 1D The display screen B shown. It can be seen that the width of the display screen B is greater than the width of the display screen A, which can meet the user's demand for a large screen.

[0034] It can be understood that under the action of the push-pull mechanism, the electronic device 1 can also be Figure 1B / Figure 1D The second push-pull state shown becomes Figure 1A / Figure 1C The first push-pull state is shown. The specific process will not be repeated any more.

[0035] At present, when the electronic device 1 switches between the first push-pull state and the second push-pull state, that is, when the rolling screen 10 is bent and retracted to the back of the electronic device 1, or rolled and unfolded to the front of the electronic device 1, the bending area 10-1 of the rolling screen 10 is easily Figure 1D The dotted box area shown in the figure) may not fit, be hollow or have gaps. For example, Figure 1E Shows Figure 1D Schematic diagram of the cross section of the dotted line box area along the CC direction. Figure 1E As shown, due to the tension of the rolling screen 10 itself and the insufficient pulling force of the push-pull mechanism, there are hollow and non-fitting problems between the bending part of the bending area 10-1 and the middle frame 21. This seriously affects the user experience.

[0036] Based on this, an embodiment of the present application proposes an elastic support solution for the rolling screen 10. A soft and hard combined support member is arranged between the rolling area 10-1 of the rolling screen 10 and the middle frame 21 to support the rolling area 10-1, thereby solving the above-mentioned problems of non-fitting, hollowing or vacant positions.

[0037] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0038] Figure 2 FIG. 1 shows a partial structural diagram of an electronic device 1 in some embodiments of the present application. It can be understood that Figure 2 The partial structure of the electronic device 1 shown may be Figure 1B Schematic diagram of the partial structure at the position shown by the circular dotted box.

[0039] In some embodiments, Figure 2 As shown, a support member 30 is provided between the curling region 10-1 and the middle frame 21. The support member 30 can support the curling region 10-1. For example, the curling region 10-1 is arranged according to Figure 2 When sliding in the direction indicated by the dashed arrow, the support member 30 can provide support force for the bending area 10-1.

[0040] In some embodiments, the support member 30 includes a first support portion 310 and a second support portion 320. The surface of the first support portion 310 is in contact with one end of the middle frame 21, the surface of the second support portion 320 is in contact with 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 is in contact with the surface of the second support portion 320 according to Figure 2 Slide in the direction indicated by the dashed arrow.

[0041] Furthermore, the deformation capacity of the first support portion 310 is greater than that 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 curling area 10-1 to slide on the surface, and the softer first support portion 310 is easily deformed by force, thereby generating a reverse support force on the curling area 10-1, thereby providing effective support for the curling area 10-1, so that the curling area 10-1 is not prone to hollowing and other problems.

[0042] For ease of understanding, the following Figure 3 The stress condition of the support member 30 is analyzed. First, Figure 3 As shown, the rolling area 10-1 of the rolling screen 10 may include a bending portion 10-11 and an extension portion 10-12, wherein the bending portion 10-11 is the portion of the rolling area 10-1 that is in a rolling state, and the extension portion 10-12 is the portion of the rolling area 10-1 that is in a flattened state. Secondly, it can be understood that the rolling screen 10 is subjected to tension F1 and tension F2 on both sides of the middle frame 21 along the Z-axis direction, wherein the tension F1 is a fixed tension from the non-rolling area 10-2, and the tension F2 is a force applied by the push-pull mechanism, which is used to drive the rolling screen 10 to move according to Figure 2 Therefore, under the action of the pulling force F1 and the pulling force F2, the bending part 10-11 will compress the support member 30, so that the softer first support part 310 is deformed to generate a reverse support force F3, thereby providing effective support for the bending part 10-11, ensuring that the rolling screen 10 is not prone to local hollowing.

[0043] 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 capacity of the first support portion 310 is greater than the deformation capacity 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 during the elastic deformation stage. Therefore, the material forming the first support portion 310 and the second support portion 320 can be selected according to the elastic modulus of the material.

[0044] In other embodiments, the materials forming the first support portion 310 and the second support portion 320 may also be selected according to strength index parameters such as yield strength and compressive strength or hardness index parameters of the material, so that the deformation capacity of the first support portion 310 is greater than the deformation capacity of the second support portion 320. For example, the yield strength, compressive strength or hardness of the material of the first support portion 310 may be less than the yield strength, compressive strength or hardness of the material of the second support portion 320.

[0045] Exemplarily, the material of the first support part 310 or the second support part 320 includes at least one of plastic, rubber, and thermosetting resin. Specifically, the material of the second support part 320 may 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 part 310 may include thermoplastic polyester elastomer (TPEE), which has good elasticity and flexibility.

[0046] In some embodiments, the first support portion 310 and the second support portion 320 are an integrated structure. Exemplarily, the first support portion 310 and the second support portion 320 can be formed into an integrated structure by a two-color injection molding process.

[0047] Alternatively, in some other embodiments, the first support portion 310 and the second support portion 320 may be bonded together by an adhesive (such as hot melt adhesive).

[0048] In some embodiments, the surface of the first support portion 310 is bonded to the middle frame 21 by an adhesive (such as hot melt adhesive).

[0049] It should be noted that, due to the various shapes of the middle frame 21 and the rolling screen 10, the specific structure of the support member 30 can be designed according to the internal space of the specific electronic device 1, the shape of the rolling screen 10 and the structure of the middle frame 21. For example, Figure 2 and Figure 3 As shown, the support member 30 may be in a “C”-shaped structure, but the present application does not limit the specific structure of the support member 30 .

[0050] The structure of the support member 30 is exemplarily described below based on two different forms of the rolling screen 10 and the structure of the middle frame 21 .

[0051] Figure 4 A partial structural schematic diagram of an electronic device 1 in some embodiments is shown. Figure 4 (b) corresponds to the first push-pull state of the electronic device 1. Figure 4 (c) corresponds to the second push-pull state of the electronic device 1, and, to facilitate understanding of the movement of the rolling screen 10, Figure 4 (a) and (d) in the figure respectively illustrate the partitions of the rolling screen 10 in the first push-pull state and the second push-pull state.

[0052] like Figure 4As shown in (b) and (c) in FIG. 1 , the roll-up screen 10 is laid on the middle frame 21, and one end 21a of the middle frame 21 along the X-axis direction can move relative to the other end 21b along the X-axis direction. One end 21a of the middle frame 21 moves toward the other end 21b, so that the electronic device 1 is in the first push-pull state, and one end 21a of the middle frame 21 moves away from the other end 21b, so that the electronic device 1 is in the second push-pull state. Figure 4 It can be seen from (b) and (c) that 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. In addition, the non-bending area 10-2 is fixed to the side of the middle frame 21 facing the positive direction of the Z axis.

[0053] like Figure 4 As shown in (a) and (b), when the electronic device 1 is in the first push-pull state, the bending area 10-1 includes a bending portion 10-11 and an extension portion 10-12, wherein the extension portion 10-12 and the non-bending area 10-2 are respectively located on both sides of the middle frame 21 along the Z-axis direction.

[0054] When one end 21a of the middle frame 21 moves away from the other end 21b, the bending portion 10-11 of the bending area 10-1 slides around one end 21a of the middle frame 21, changing from a bent state to a flat state. The extension portion 10-12 slides around one end 21a of the middle frame 21, changing from a flat state to a bent state.

[0055] For example, from Figure 4 (b) to Figure 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, Figure 4 The turning part 10-11 shown in (a) is in accordance with Figure 4 In the direction indicated by the dotted arrow shown in (b), the bending portion 10-11 slides around one end 21a of the middle frame 21 to the side of the middle frame 21 facing the positive direction of the Z axis, and changes from a rolled state to a flattened state, that is, the bending portion 10-11 moves to the surface of the side of the middle frame 21 facing the positive direction of the Z axis. Figure 4 The extension portion 10 - 12 shown in (a) slides around one end 21 a of the middle frame 21 from the middle frame 21 toward the negative direction of the Z axis, and changes from a flat state to a rolled state.

[0056] like Figure 4 As shown in (c) and (d), when the electronic device 1 is in the second push-pull state, the bending area 10-1 includes a bending portion 10-11 and two extension portions 10-12, wherein the two extension portions 10-12 are respectively 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 direction of the Z-axis is in the same plane as the non-bending area 10-2.

[0057] When one end 21a of the middle frame 21 moves toward the other end 21b, the bending portion 10-11 slides around the one end 21a of the middle frame 21, changing from a rolled state to a flat state. The extension portion 10-12 located on the side of the middle frame 21 facing the positive direction of the Z axis slides around the one end 21a of the middle frame 21, changing from a flat state to a rolled state.

[0058] For example, from Figure 4 (c) to Figure 4 In the state shown in (b), one end 21a of the middle frame 21 moves toward the other end 21b. At this time, Figure 4 The turning part 10-11 shown in (d) is in accordance with Figure 4 In the direction indicated by the dotted arrow shown in (c), it slides around one end 21a of the middle frame 21 to the side of the middle frame 21 facing the negative direction of the Z axis, becoming the extension portion 10-12, and changes from a bent state to a flattened state, that is, the bending portion 10-11 moves to the surface of the side of the middle frame 21 facing the negative direction of the Z axis. Figure 4 As shown in (d), the extension portion 10 - 12 located on the side of the middle frame 21 facing the positive direction of the Z axis slides around one end 21 a of the middle frame 21 and changes from a flat state to a rolled state.

[0059] It is understandable that Figure 4 As shown in (c) and (d), the extension portion 10-12 located on the side of the middle frame 21 facing the positive direction of the Z axis is originally in a flattened state. When one end 21a of the middle frame 21 moves toward the other end 21b, the extension portion 10-12 moves along the Figure 4 The device slides in the direction indicated by the dotted arrow in (c) to become the bending portion 10-11, that is, changes from a flat state to a rolled state.

[0060] In this embodiment, one end 21a of the middle frame 21 has a protrusion, and accordingly, the shape of the support member 30 is roughly "C"-shaped. Figure 5 .

[0061] like Figure 5 As shown, in some embodiments, the surface 310a where the first support portion 310 and the middle frame 21 are attached is in an arc shape, and the interface 320a between the first support portion 310 and the second support portion 320 is in an arc intersection line with the XZ plane (the first plane of the present application). The arc intersection line has one end M and the other end N along its extension direction. Figure 4 As shown in (a) and (b), one end M of the arc boundary line is aligned with the connection between the bending portion 10-11 and the non-curling area 10-2, and the other end N of the arc boundary line is aligned with the connection between the bending portion 10-11 and the extension portion 10-12.

[0062] Continue reading Figure 5In some embodiments, the second support portion 320 is crescent-shaped, and the first support portion 310 includes two sub-support portions 310-1 and 310-2. The two sub-support portions 310-1 and 310-2 are symmetrically arranged at both ends of the crescent relative to the first axis, wherein the first axis is parallel to the X-axis direction.

[0063] The two sub-support parts 310-1 and 310-2 have the same structure. Taking the sub-support part 310-1 as an example, the thickness of the sub-support part 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 part 10-11 and the non-bending area 10-2, and the connection between the bending part 10-11 and the extension part 10-12 are more likely to have hollowing phenomenon. Therefore, the thickness of the sub-support part 310-1 near the connection between the bending part 10-11 and the non-bending area 10-2 is larger, and the thickness of the sub-support part 310-2 near the connection between the bending part 10-11 and the extension part 10-12 is larger, so as to provide a stronger support force for the rolling screen 10.

[0064] Continue reading Figure 5 In this embodiment, the rolling screen 10 is only in contact with the surface of the second support portion 320 , and the surface of the second support portion 320 may be polished to improve the sliding smoothness of the rolling screen 10 .

[0065] It should be noted that the present application does not limit the shapes of the two sub-support portions of the first support portion 310 and the second support portion 320 . FIG. 6A to FIG. 6C Several other possible examples are shown.

[0066] like Fig. 6A As shown, in the XZ plane, the second support portion 320 is semicircular, and the interface between the first support portion 310 and the second support portion 320 and the boundary line of the XZ plane are straight. In this example, the rolling screen 10 can contact the two sub-support portions 310-1 and 310-2, and the two sub-support portions 310-1 and 310-2 can provide reverse support force to the rolling screen 10 when compressed by the rolling screen 10, so that the rolling screen 10 is not prone to hollowing.

[0067] like Figure 6B As shown, in the XZ plane, the two sub-supporting parts 310-1, 310-2 and the second supporting part 320 may also be fan-shaped. Figure 6C As shown, the two sub-support portions of the first support portion 310 and the second support portion 320 may also be other special-shaped structures, which is not limited in the present application.

[0068] In addition, the embodiment of the present application does not limit the number of sub-support portions of the first support portion 310 , and the first support portion 310 may be disassembled into a greater or lesser number of sub-support portions according to actual application scenarios.

[0069] Figure 7 Partial structural schematic diagrams of electronic devices 1 in other embodiments are shown. Figure 7 (a) corresponds to the first push-pull state of the electronic device 1. Figure 7 (b) corresponds to the second push-pull state of the electronic device 1 .

[0070] Figure 7 The electronic device 1 is shown with Figure 4 The difference between the electronic device 1 shown is that the structure of the middle frame 21 and the form of the rolling screen 10 are different. For example, Figure 4 The rolling screen 10 shown in the figure can be bent in a "U" shape. Figure 7 The roll-up screen 10 shown is capable of being rolled up in a "P" shape.

[0071] like Figure 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, wherein the rolling screen 10 can bend and roll around the first structural member 21-1, and roll up to the gap between the second structural member 21-2 and the third structural member 21-3, wherein the second structural member 21-2 and the third structural member 21-3 can be extended and retracted along the X-axis direction. It should be noted that the present 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 of the first structural member 21-1, the second structural member 21-2 and the third structural member 21-3 can be an integrated structure, for example, the first structural member 21-1 and the second structural member 21-2 are an integrated structure, or each structural member is independent of each other.

[0072] In some embodiments, the first structural member 21 - 1 extends along the Y-axis direction and can rotate around its own axis.

[0073] For example, from Figure 7 Middle (a) to Figure 7 In the state shown in (b) of FIG. 1 , the second structural member 21 - 2 and the third structural member 21 - 3 are stretched in the X-axis direction. At this time, the rolling sliding screen 10 located between the second structural member 21 - 2 and the third structural member 21 - 3 is arranged according to Figure 7 In the direction indicated by the dashed arrow in (a), slide around the first structure 21-1 to the side of the second structure 21-2 facing the positive direction of the Z axis. Figure 7 Middle (b) to Figure 7 In the state shown in (a), the second structure 21-2 and the third structure 21-3 are contracted in the X-axis direction. At this time, the part of the rolling sliding screen 10 located on the side of the second structure 21-2 facing the positive direction of the Z-axis is Figure 7In the direction indicated by the dotted arrow shown in (b), the first structure member 21 - 1 slides to the gap between the second structure member 21 - 2 and the third structure member 21 - 3 .

[0074] It can be understood that there are also problems of hollowing and non-fitting between the rolling screen 10 and the first structural member 21 - 1 .

[0075] Figure 8 A partial structural schematic diagram of the electronic device 1 after the support member 30 is added is shown.

[0076] like Figure 8 As shown, in this embodiment, the support member 30 is arranged around the first structural member 21 - 1 , and the first support portion 310 is arranged in contact with the first structural member 21 - 1 , and the second support portion 320 is arranged on the periphery of the first support portion 310 and contacts the rolling screen 10 .

[0077] The first support portion 310 may include two sub-support portions 310-1 and 310-2, which 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.

[0078] In addition, the second support portion 320 may also be crescent-shaped, and the number of the second support portions 320 may be two, and the two second support portions 320 are symmetrically arranged along an axis parallel to the Z-axis direction.

[0079] It should be noted that Figure 8 The structure of the middle support member 30 is only used as an example. In actual applications, the sub-support parts 310 - 1 and 310 - 2 can be set corresponding to the positions where hollowing is likely to occur.

[0080] It can be understood that the performance and material of the first support portion 310 and the second support portion 320 can refer to Figure 2 The relevant embodiments will not be described in detail here.

[0081] The following is based on Figure 4 Related embodiments, combined with Fig. 9 The push-pull mechanism 40 in some embodiments of the present application is introduced. Figure 1B As shown, the position of the push-pull mechanism 40 in some embodiments of the present application may be as shown in the rectangular dotted box.

[0082] like Fig. 9As shown, the push-pull mechanism 40 at least includes a first connection block 410, a second connection block 420, a fixed pulley 430, a rope 440 (such as a steel wire rope) and a motor (not shown). One end of the rope 440 is connected to the first connection block 410, and the other end is connected to the second connection block 420. The second connection block 420 and the fixed pulley 430 are both fixed parts. Under the drive of the motor, the first connection block 410 can move in the X-axis direction.

[0083] In addition, the first connecting block 410 and the second connecting block 420 are respectively connected to the middle frame 21. Therefore, 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 rolling screen 10 to move in contact with the middle frame 21, and form a rolling curtain movement around one end 21a of the middle frame 21.
