DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0054] It should be understood that the directional terms used in the embodiments of the present disclosure, such as "upper," "lower," "top," "bottom," and "side," are based on the orientation of the first and second parts of the housing. The orientation of the second part is referred to as the top, the orientation of the first part is referred to as the bottom, and the area between the top and bottom is referred to as the side. These directional terms are used in the embodiments of the present disclosure solely to more clearly describe the relationships between structures, and are not intended to describe absolute orientations. Therefore, they should not be construed as limitations on the present disclosure.

[0055] It should be understood that in this disclosure, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0056] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0057] As one of the most important features of mobile terminals, display devices require portability. However, due to the portability of these devices, the display screen size of portable display devices is generally limited to less than 7 inches. To enable portable display devices with larger display sizes, electronic devices using flexible displays have emerged.

[0058] In the related art, an electronic device with a scroll screen structure includes a housing, a scroll, a flexible display, and a drive mechanism. The housing is divided into a first part and a second part that can move relative to each other, and the scroll is rotatably arranged on the first part. The first end of the flexible display is fixedly connected to the second part, and the second end of the flexible display is rolled up on the scroll. The area between the first end of the flexible display and the scroll is the display area. The drive mechanism includes a motor and two transmission structures. The motor is fixed to the second part, and the two transmission structures are a gear rack structure and a dual-gear structure. The motor drives the first part to move closer to or away from the second part through the gear rack structure, and drives the scroll to rotate through the dual-gear structure. When the first and second parts approach each other, the flexible display is rolled up, and when the first and second parts move away from each other, the flexible display is released, thereby adjusting the size of the display.

[0059] However, the structure of such electronic devices is complex and has many types of parts, which not only increases the production cost but also is not conducive to the development of thinner and lighter electronic display devices.

[0060] The present disclosure provides an electronic device that uses two magnetic devices as a driving mechanism. The two magnetic devices drive the two parts of the shell to slide relative to each other through the magnetic force of attraction or repulsion. The driving mechanism has a simple structure and is easy to install, which is conducive to controlling the production and manufacturing costs of the product and is conducive to the development of lighter and thinner electronic devices.

[0061] Figure 1 The structure of the electronic device provided by the embodiment of the present disclosure is shown. Figure 2 FIG. 3 is a diagram showing the size adjustment of the display portion 31 of the electronic device provided by the embodiment of the present disclosure.

[0062] Combine Figure 1 、 2 As shown, an embodiment of the present disclosure provides an electronic device, which includes: a shell 1, a driving mechanism 2, a flexible display screen 3 and a scroll 4; the shell 1 includes a first part 11 and a second part 12; the driving mechanism 2 includes a first magnetic device 21 and a second magnetic device 22; the first magnetic device 21 is connected to the first part 11, and the second magnetic device 22 is connected to the second part 12, and the first magnetic device 21 and the second magnetic device 22 interact with each other through magnetic force to make the first part 11 and the second part 12 slide relative to each other.

[0063] In the electronic device of the disclosed embodiment, the housing 1 is divided into two parts that can slide relative to each other. When the two parts slide relative to each other, the scroll 4 releases or reels the flexible display screen 3 to adjust the size of the display part 31. Two magnetic devices are used as the driving mechanism 2. The two magnetic devices drive the two parts of the housing 1 to slide relative to each other through the magnetic force of attraction or repulsion. The driving mechanism 2 has a simple structure and is easy to install, which is conducive to controlling the production and manufacturing cost of the product and is conducive to the development of lightweight and thin electronic equipment.

[0064] In addition, compared with the mechanical drive mechanism of motors, gears and racks used in the prior art, the two magnetic devices used in the embodiment of the present disclosure generate magnetic force through the superposition of magnetic fields. The transmission of force is not affected by the structure between the two, thus realizing non-contact drive. On the one hand, it can improve the arrangement freedom of the drive mechanism 2. On the other hand, the magnetic device has a simple structure, no contact wear, high reliability and long service life.

[0065] It is understood that the electronic devices of the embodiments of the present disclosure include but are not limited to display devices such as mobile phones, tablets, or other portable display devices. In the present disclosure, the electronic device is described as a mobile phone as an example.

[0066] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of this disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0067] In addition, in the present disclosure, unless otherwise expressly specified and limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0068] Optionally, a slide rail and a slider are provided between the first part 11 and the second part 12, and the slide rail and the slider slide together to achieve sliding between the first part 11 and the second part 12. In some possible implementation examples, the slide rail extends along the sliding direction of the two parts, and the slider is slidably mounted on the slide rail.

[0069] Exemplarily, the first part 11 and / or the second part 12 is at least one of non-magnetic metal, glass, ceramic, and plastic, the slide rail and / or slider is at least one of non-magnetic metal and ceramic, and the slide rail and / or slider are integrally formed on the first part 11 or the second part 12, such as by molding injection molding or split casting process.

[0070] Optionally, a dynamic sealing structure is provided between the first portion 11 and the second portion 12 to ensure that the mating surfaces of the first portion 11 and the second portion 12 maintain a good seal during the relative sliding of the first portion 11 and the second portion 12. For example, the dynamic sealing structure is a sealing rubber ring.

[0071] Understandably, in Figure 2 In the diagram of the size adjustment of the display portion 31 of the electronic device, the left side shows the initial size of the display portion 31 of the electronic device, and the right side shows the expanded size of the display portion 31 of the electronic device. The horizontal size of the display portion 31 in the expanded state in the right figure is larger than the horizontal size of the display portion 31 in the initial state in the left figure. In addition, the size that the display portion 31 of the electronic device can be expanded is not limited to Figure 2 The size shown, Figure 2 The size of the display portion 31 can also be any size between the minimum size (such as the initial state) and the maximum size (such as the expanded state).

[0072] Optionally, the first part 11 and the second part 12 are directly slidably matched, one of the first part 11 and the second part 12 is provided with a slide groove, and the other of the first part 11 and the second part 12 is provided with a convex shaft or a bump, and the convex shaft or the bump is slidably matched in the slide groove.

[0073] Exemplarily, the convex shaft or the convex block is integrally formed on the first part 11 or the second part 12 .

[0074] Combine Figure 1 As shown, in some embodiments, the first portion 11 has a first side wall 111, which corresponds to the side of the display portion 31; the first magnetic device 21 is arranged on the inner side of the first side wall 111, and the inner side of the first side wall 111 is the side of the first side wall 111 facing the second portion 12.

[0075] In the electronic device of this embodiment, the first magnetic device 21, as part of the drive mechanism 2, acts as a force-applying component for the first portion 11. Considering its placement within the first portion 11, it is necessary to consider placing it in a location that provides greater strength while also avoiding interference with the internal structure of the first portion 11. As the exterior structure of the electronic device, the first sidewall 111 requires high strength to protect the internal structure and is located at the outermost edge of the device. Therefore, placing the first magnetic device 21 on the inner surface of the first sidewall 111 ensures the structural strength of the first portion 11 while avoiding interference with the internal structure.

[0076] Combine Figure 1 As shown, in some embodiments, the first magnetic device 21 is an arched piece, and the first magnetic device 21 is embedded on the inner side of the first side wall 111 , and the outer surface of the first magnetic device 21 matches the inner side of the first side wall 111 .

[0077] Optionally, a groove structure is provided on the inner side surface of the first side wall 111 , and the groove structure corresponds to the shape of the first magnetic device 21 , and the first magnetic device 21 is snapped or bonded into the groove structure.

[0078] In the electronic device of this embodiment, the first magnetic device 21 is designed as an arched member and is embedded on the inner surface of the first side wall 111. Its outer surface is flush with the inner surface of the first side wall 111. The concealed installation of the first magnetic device 21 does not affect the reference and fit requirements of the inner surface of the first side wall 111 and the internal structure of the first part 11.

[0079] In addition, directly clamping or bonding the first magnetic device 21 to the inner side surface of the first side wall 111 is simple and convenient, does not require major changes to the existing structure, and can greatly reduce the difficulty of producing the flexible display device.

[0080] Combine Figure 1 As shown, in some embodiments, the scroll 4 is rotatably arranged in the first part 11; the first end of the flexible display screen 3 is connected to the outer surface of the second part 12, and the second end is connected to the scroll 4. When the first part 11 and the second part 12 slide relative to each other, the scroll 4 rotates to release or reel in the flexible display screen 3 to adjust the size of the display part 31 of the flexible display screen 3.

[0081] In some feasible embodiments, the scroll 4 is arranged close to the first side wall 111, and the inner side surface of the first side wall 111 is provided with a cylindrical groove whose shape corresponds to the outer cylindrical surface of the scroll 4, and the scroll 4 and the flexible display screen 3 rolled up on its outer circumference can be accommodated in the cylindrical groove.

[0082] Combine Figure 3As shown, in some embodiments, the electronic device further includes a limiting roller 7; the limiting roller 7 is rotatably arranged in the first part 11 and is parallel to the scroll 4; the turning part 32 of the flexible display screen 3 is wound around the limiting roller 7; the turning part 32 is located between the display part 31 and the second end of the flexible display screen 3, and the first end and the second end of the flexible display screen 3 are both located on the same side of the limiting roller 7.

[0083] In the electronic device of this embodiment, a limiting roller 7 is provided at the first side wall 111, the scroll 4 is away from the first side wall 111, the first end and the second end of the flexible display screen 3 are both located on the same side of the limiting roller 7, and the turning part 32 is wound on the other side of the limiting roller 7. The central angle of the limiting roller 7 corresponding to the turning part 32 is approximately 180°.

[0084] By adding a limiting roller 7, the length of the flexible display 3 can be increased. The second end of the flexible display 3 is connected to the outer surface of the second portion 12, and the first end is connected to the reel 4. The limiting roller 7 makes a turn in the middle. The length of the flexible display 3 can be increased by at least the distance between the limiting roller 7 and the reel 4. Furthermore, the increased portion of the flexible display 3 is unfolded and accommodated within the cavity enclosed by the first portion 11 and the second portion 12. There is no need to worry that the diameter of the excess flexible display 3 will increase when it is fully reeled onto the reel 4, thereby interfering with the housing 1 and other structures.

[0085] Optionally, the second end of the flexible display screen 3 is connected to the reel 4 via a connector, so that the second end of the flexible display screen 3 can be released and moved away from the surface of the reel 4 until the second end coincides with the turning portion 32. At this point, the display portion 31 of the flexible display screen 3 is the entire area between the first and second ends, fully utilizing the flexible display screen 3 and improving the utilization rate of the flexible display device. Exemplarily, the connector is a flexible circuit board.

[0086] Optionally, the diameter of the limiting roller 7 is larger than the diameter of the scroll 4. When the limiting roller 7 is arranged in the first part 11, the distance between the limiting roller 7 and the bottom surface of the first part 11 and the inner surface of the first side wall 111 is equal to the thickness of the flexible display screen 3, and one of the busbars of the outer peripheral surface of the limiting roller 7 is located in the plane where the outer surface of the second part 12 is located.

[0087] Therefore, in this embodiment, the gap between the limiting roller 7 and the shell 1 can be designed to be smaller, only accommodating the flexible display screen 3 to pass through in a single layer, without reserving other gaps, and the gap is always occupied by the flexible display screen 3, which can ensure the airtightness of the internal space of the shell 1.

[0088] In some feasible embodiments, the limiting roller 7 and the turning portion 32 disposed around the outer circumference thereof can be accommodated in a cylindrical groove on the inner side surface of the first side wall 111 .

[0089] Combine Figure 3 As shown, in some embodiments, the first magnetic device 21 is rotatably disposed in the limiting roller 7 , and the first magnetic device 21 transmits a force to the first portion 11 through the limiting roller 7 .

[0090] In this embodiment, the limiting roller 7 is rotatably installed in the first part 11 and can slide relative to the second part 12 with the first part 11. The outer periphery of the limiting roller 7 supports the turning part 32 of the flexible display screen 3. The interior of the limiting roller 7 is hollow, but because the space is relatively closed and the limiting roller 7 is in a rotating state at all times, it cannot accommodate other electrical components of the electronic device.

[0091] However, in this embodiment, the first magnetic device 21 can achieve a contactless magnetic interaction with the second magnetic device 22, and is not subject to interference from the non-magnetic structure between the two. Therefore, when the first magnetic device 21 is disposed within the limiting roller 7, the first magnetic device 21 and the second magnetic device 22 can still penetrate the limiting roller 7 to generate a mutual magnetic interaction. Thus, this embodiment fully utilizes the space inside the limiting roller 7 and improves the integration of the flexible display device.

[0092] Combine Figure 4 As shown, in some embodiments, the first magnetic device 21 is a cylindrical member, the axis of the first magnetic device 21 coincides with the axis of the limiting roller 7, and the first magnetic device 21 can rotate inside the limiting roller 7. Regardless of the angle to which the limiting roller 7 rotates, the direction of the first magnetic device 21 always remains corresponding to the second magnetic device 22.

[0093] Combine Figure 1 、 3 As shown, in some embodiments, the second part 12 has a top plate 121, which is arranged on the non-display surface of the display part 31, and the top surface of the top plate 121 is supported on the non-display surface of the display part 31, so that the display part 31 of the flexible display screen 3 remains flat and stable, and the display part 31 can display normally; the second magnetic device 22 is arranged on the bottom surface of the top plate 121, and the bottom surface of the top plate 121 is the side of the top plate 121 away from the display part 31, and the bottom surface of the top plate 121 faces the inside of the cavity surrounded by the first part 11 and the second part 12. The second magnetic device 22 is arranged on the bottom surface of the top plate 121, which can not only realize the connection with the second part 12, but also facilitate the second magnetic device 22 to approach the first magnetic device 21 on the first part 11.

[0094] For example, in combination Figure 5As shown, the second part 12 also includes a second side wall 122 and two second end walls 123. The second side wall 122 is arranged on the first side 1211 of the top plate 121, and the second side 1212 is located on the opposite side of the first side 1211. The two second end walls 123 are respectively arranged on the third side 1213 and the fourth side 1214 adjacent to the first side 1211. The second side wall 122 and the two second end walls 123 extend respectively along the side of the top plate 121 toward the side where the first part 11 is located.

[0095] The first part 11 also includes a bottom plate 112 and two first end walls 113. The first side wall 111 is arranged on the fifth side 1121 of the bottom plate 112, and the sixth side 1122 is located on the opposite side of the fifth side 1121. The two first end walls 113 are respectively arranged on the seventh side 1123 and the eighth side 1124 adjacent to the fifth side 1121. The first side wall 111 and the two first end walls 113 extend respectively along the side of the bottom plate 112 toward the side where the second part 12 is located.

[0096] When the first part 11 and the second part 12 are slidably connected, the two first end walls 113 and the two second end walls 123 slide together, and the cooperation methods include but are not limited to the two second end walls 123 being located between the two first end walls 113 (first end wall 113, second end wall 123, second end wall 123, first end wall 113), the two first end walls 113 being located between the two second end walls 123 (second end wall 123, first end wall 113, first end wall 113, second end wall 123), and the two second end walls 123 being inserted into the interior of the two first end walls 113, and the two first end walls 113 being inserted into the inner walls of the two second end walls 123.

[0097] After the first part 11 and the second part 12 are slidably connected, the top plate 121 is parallel to the bottom plate 112, and the area between the top plate 121 and the bottom plate 112 can accommodate the scroll 4, the second end of the flexible display screen 3, the second magnetic device 22, and other electrical components of the electronic device.

[0098] Exemplarily, other electrical components of the electronic device include, but are not limited to, batteries, main boards, sub-boards, flexible circuit boards, sensors, and camera modules.

[0099] Optionally, in order to solve the problem that the bottom is exposed due to insufficient length of the bottom plate 112 when the first part 11 and the second part 12 are relatively far apart, the second part 12 also includes a sub-bottom plate 124. The sub-bottom plate 124 is parallel and tightly attached to the bottom plate 112, and is used to extend the length of the bottom plate 112 when the first part 11 and the second part 12 are relatively far apart, so as to seal the bottom and prevent internal electrical components from being exposed and damaged.

[0100] In some possible implementations, the bottom plate 112 can be extended and retracted along the direction in which the first portion 11 and the second portion 12 slide relative to each other.

[0101] Combine Figure 6 As shown, in some embodiments, the top plate 121 includes at least two support members 125 and a flexible member 126 connecting two adjacent support members 125; at least two support members 125 are arranged side by side; the top plate 121 is used to support the display portion 31 and to extend and retract along the direction of size change of the display portion 31.

[0102] Optionally, the support member 125 is in an elongated strip shape, and both ends of the elongated support member 125 can be slidably connected to the two first end walls 113 of the first portion 11 respectively.

[0103] Optionally, the flexible member 126 is a flexible element such as a spring or a colloid, which can be bent or compressed to change its width, thereby changing the size of the top plate 121 .

[0104] In the electronic device of this embodiment, the top plate 121 can expand and contract as the size of the display portion 31 changes, so that the non-display surface of the display portion 31 always has a reliable support structure, ensuring the normal operation of the display portion 31.

[0105] Combine Figure 7 As shown, in some embodiments, the direction of the internal magnetic field of the first magnetic device 21 is collinear with the direction of the internal magnetic field of the second magnetic device 22. Therefore, due to the magnetic field intensity distribution characteristics of the magnetic devices, when the two magnetic devices are collinearly arranged, the magnetic force generated between them is the strongest, ensuring a sufficiently large relative sliding force between the first portion 11 and the second portion 12.

[0106] In some embodiments, at least one of the first magnetic device 21 and the second magnetic device 22 is an electromagnet.

[0107] Related technologies use motors for driving, but these motors are noisy, resulting in a poor user experience. This embodiment uses electromagnets to address this noise issue. Furthermore, the strength of the electromagnet's magnetism can be altered by varying the current and the number of coil turns. Controlling the on / off current controls the presence of magnetism, while changing the current direction changes the orientation of the magnetic poles. This embodiment incorporates an electromagnet within the housing 1. By changing the current direction, the electromagnet's magnetic poles shift, allowing the first portion 11 and the second portion 12 to move closer or further apart.

[0108] In some embodiments, the second magnetic device 22 is an electromagnet, and the first magnetic device 21 is a neodymium iron boron permanent magnet.

[0109] Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron. They have large coercive force and magnetic energy product, and can withstand long periods of time without demagnetization, ensuring the long-term reliability of magnetic devices.

[0110] Combine Figure 1 As shown, in some embodiments, two drive mechanisms 2 are provided; the two drive mechanisms 2 are spaced apart along the axial direction of the reel 4. Consequently, in this embodiment of the electronic device, the first portion 11 and the second portion 12 are subjected to uniform force along the length of the housing 1, ensuring stable sliding of the two portions. The length of the housing 1 is aligned with the axial direction of the reel 4.

[0111] Combine Figure 8 As shown, in some embodiments, the electronic device further includes: a positioning assembly 5; the positioning assembly 5 includes a positioning rod 51 and a positioning block 52; the positioning block 52 is provided with a positioning hole 521, and the positioning rod 51 is slidably set in the positioning hole 521; the positioning rod 51 is connected to one of the first part 11 and the second part 12, and the positioning block 52 is connected to the other of the first part 11 and the second part 12.

[0112] Optionally, there is a certain amount of damping between the positioning rod 51 and the positioning hole 521. When the first part 11 and the second part 12 are relatively far apart, the longer the positioning rod 51 extends from the positioning hole 521, the greater the damping, and the greater the magnetic force required at this time. When one of the two magnetic devices is an electromagnet, according to the characteristic that the greater the current of the electromagnet, the greater the magnetic force, when the current is increased, because the magnetic force is greater than the damping force, the first part 11 and the second part 12 continue to move away from each other until the damping force and the magnetic force are equal, and the first part 11 and the second part 12 are maintained in their current position. Therefore, the electronic device of this embodiment can control the relative distance between the first part 11 and the second part 12 by controlling the current of the electromagnet, that is, it can control the size of the display part 31 of the flexible display screen 3.

[0113] Combine Figure 8 、 9 As shown, in some embodiments, the positioning assembly 5 also includes an identification circuit 53; the positioning rod 51 is provided with at least two conductive members 511, and the at least two conductive members 511 are arranged at intervals along the axial direction of the positioning rod 51; two conductive contacts 5211 are provided in the positioning hole 521, and the two conductive contacts 5211 are respectively arranged at both ends of the identification circuit 53; when the conductive member 511 moves to a contact position with the two conductive contacts 5211, the identification circuit 53 is turned on; the identification circuit 53 counts the number of conductive members 511 passing through the conductive contacts 5211.

[0114] The conductive member 511 slides in the positioning hole 521 along with the positioning rod 51. When the conductive member 511 slides through the positioning hole 521, it can cause the two conductive contacts 5211 to be instantly turned on, and the current signal is captured by the identification circuit 53. The identification circuit 53 records or feeds back the number of current signals. The number of current signals can be used to calculate the number of conductive members 511 passing through the positioning hole 521, and then determine the length of the positioning rod 51 passing through the positioning hole 521, and finally calculate the relative sliding distance between the first part 11 and the second part 12.

[0115] Optionally, at least two conductive members 511 evenly divide the positioning rod 51 into at least three sections, each section of the positioning rod 51 having the same length and corresponding to the first target value. The relative sliding distance between the first section 11 and the second section 12 = the first target value × the count value of the conductive member 511.

[0116] Optionally, at least two conductive members 511 unevenly divide the positioning rod 51 into at least three sections, with the length of each section of the positioning rod 51 corresponding to a different second target value, third target value, and so on. For example, the second target value corresponds to a relative sliding distance of 0 between the first portion 11 and the second portion 12, at which point the electronic device is in an initial state; the Nth target value corresponds to a relative sliding distance of the first portion 11 and the second portion 12 being at its maximum, at which point the electronic device is in an expanded state; and the third target value corresponds to a relative sliding distance between the first portion 11 and the second portion 12 being between 0 and the maximum, at which point the electronic device is in a semi-expanded state.

[0117] It is understandable that the user can set the relative sliding distance between the first part 11 and the second part 12 corresponding to the second target value, the third target value, ... the Nth target value to meet the device usage requirements in different scenarios.

[0118] Optionally, at least two conductive members 511 have different conductive properties. When different conductive members 511 pass through the conductive contact 5211, the identification circuit 53 receives different currents. The positions of the different conductive members 511 are then associated with specific distances between the first portion 11 and the second portion 12, or the different conductive members 511 are arranged at different positions on the positioning rod 51 based on the specific distance between the first portion 11 and the second portion 12. When the identification circuit 53 detects a specific current, it can identify the specific conductive member 511 based on the current magnitude, and further determine the specific distance between the first portion 11 and the second portion 12.

[0119] Combine Figure 8As shown, in some embodiments, a stopper 512 is provided at the end of the positioning rod 51. The stopper 512 is used to limit the position of the positioning rod 51 when sliding in the positioning hole 521. The stopper 512 is used to define the extreme positions of the first portion 11 and the second portion 12, preventing the first portion 11 and the second portion 12 from sliding too far and causing damage to the flexible display screen 3.

[0120] In some embodiments, the electronic device also includes a control module; the control module is configured to receive the relative sliding distance between the first part 11 and the second part 12, calculate the target count value based on the relative sliding distance, and control the action of at least one driving mechanism 2 until the count value feedback from the identification circuit 53 is equal to the target count value.

[0121] Optionally, the user selects the size of the display portion 31 through the mobile phone interface. The control module calculates the extension distance of the positioning rod 51 based on the corresponding size of the display portion 31, and then determines the target count value of the conductive member 511 that needs to pass through the conductive contact 5211. Based on the calculation results, the control module controls the electromagnet to be powered on and controls the increase of the driving current. The magnetic force of the electromagnet increases with the increase of the driving current, and the positioning rod 51 continues to extend. Each time it extends a certain distance, so that the conductive member 511 passes the conductive contact 5211, the identification circuit 53 counts once. When the target count value is reached, the current stops increasing. The control module controls the current size of the position, and the balance of the magnetic force and the damping force, thereby fixing the first part 11 and the second part 12 in this position.

[0122] Combine Figure 1 、 4 As shown, in some embodiments, the reel 4 is provided with a restoring element 6; this restoring element 6 is used to provide a restoring force when the first portion 11 and the second portion 12 slide relative to each other. Under the restoring force of the restoring element 6, the reel 4 maintains a tendency to retract the flexible display 3 onto the surface of the reel 4. When the first portion 11 and the second portion 12 move away from each other, the first end of the flexible display 3 overcomes the restoring force and is pulled out. When the first portion 11 and the second portion 12 move closer together, the first end of the flexible display 3 is acted upon by the restoring force and moves closer to the reel 4.

[0123] The presence of the restoring element 6 enables the scroll 4 to always apply tension to the flexible display screen 3 through the second end of the flexible display screen 3, keeping the unfolded part of the flexible display screen 3 in a stretched state, and preventing wrinkles and other unevenness from occurring on the surface of the flexible display screen 3.

[0124] Combine Figure 1 、 4As shown, in some embodiments, the restoring element 6 is a torsion spring, which is disposed at one axial end of the reel 4 and connected to the first portion 11. The torsion spring has the same diameter as the reel 4, is mounted at one axial end of the reel 4, and is connected to the first portion 11, applying a restoring force to the reel 4 via the first portion 11. Of course, the restoring element 6 can also be a member having elastic restoring force, such as rubber.
