[0069] Embodiments of the disclosure provide an electronic device having a stretched state and a retracted state, and the display screen size of the electronic device is different in different states. In this way, different needs of users are met, and the use experience is optimized.

[0070] In embodiments of the disclosure, the electronic device includes, but is not limited to, a smartphone, a tablet computer, a desktop / laptop / handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a personal digital assistant (PDA), an augmented reality (AR) / virtual reality (VR) device. The drawings only take a mobile phone as an example for display.

[0071] Figure 1 is an exploded view of an electronic device according to an example embodiment. As shown in Figure 1 , the electronic device includes a flexible display screen 100 and a telescopic driving mechanism 200.

[0072] Figure 2 is a structural schematic diagram of a flexible display screen according to an example embodiment. As shown in Figure 2As shown, the flexible display screen 100 includes a first end 110 and a second end 120 arranged oppositely. The flexible display screen 100 has a bending form. The flexible display screen 100 extends from the front surface of the electronic device to the back surface of the electronic device via the side surface of the electronic device. The first end 110 is arranged on the front surface of the electronic device, and the second end 120 is arranged on the back surface of the electronic device.

[0073] The telescopic driving mechanism 200 includes a housing 210 and a movable assembly 220. The movable assembly 220 is in sliding connection with the housing 210 and can be driven to move close to or away from the housing 210. The housing 210 is connected with the first end 110 of the flexible display screen 100, and the movable assembly 220 is connected with the second end 120 of the flexible display screen 100. At this time, the second end 120 moves close to or away from the first end 110 along with the movement of the movable assembly 220 relative to the housing 210.

[0074] When the movable assembly 220 moves away from the housing 210, the electronic device is in the stretched form. At this time, the second end 120 of the flexible display screen 100 moves away from the first end 110. Accordingly, the part of the flexible display screen 100 located on the back surface of the electronic device is turned to the front surface of the electronic device. At this time, the size of the display screen on the front surface of the electronic device is increased.

[0075] When the movable assembly 220 moves close to the housing 210, the electronic device is in the retracted form. At this time, the second end 120 of the flexible display screen 100 moves close to the first end 110. Accordingly, the part of the flexible display screen 100 located on the front surface of the electronic device is turned to the back surface of the electronic device. At this time, the size of the display screen on the front surface of the electronic device is reduced.

[0076] In this way, the electronic device provided by the embodiment of the present disclosure can be switched between the stretched form and the retracted form. And through the stretched form and the retracted form, different sizes of display areas are realized on the front surface of the electronic device. In this way, the electronic device can adapt to different use scenarios and meet different user needs, and the user experience is optimized.

[0077] In one embodiment, continuing to refer to Figure 1 The movable assembly 220 includes a movable member 220A and a telescopic elastic member 220B connected with each other. That is, the telescopic driving mechanism 200 includes the housing 210, the movable member 220A and the telescopic elastic member 220B, and the telescopic driving mechanism 200 is a key component in the electronic device provided by the embodiment of the present disclosure. The implementation mode of the telescopic driving mechanism 200 will be specifically introduced below in combination with the drawings.

[0078] First, the structure of the housing 210 and the movable member 220A.

[0079] The movable member 220A is movably connected with the housing 210, and is arranged to abut the part of the flexible display 100 corresponding to the side of the electronic device. The movable member 220A is driven to move relative to the housing 210 to apply a force to the part of the flexible display 100 corresponding to the side of the electronic device, thereby causing the second end 120 of the flexible display 100 to move away from the first end 110 to switch to the unfolded state.

[0080] Figure 3 is a schematic view of the assembly of the movable member and the housing according to an example embodiment. As shown in Figure 3 The telescopic driving mechanism 200 further comprises a driving assembly 230. One end of the driving assembly 230 is connected with the housing 210, and the other end is connected with the movable member 220A. The driving assembly 230 is configured to drive the movable member 220A to move towards or away from the housing 210.

[0081] The housing 210 is configured to be connected with the first end 110 of the flexible display 100. Optionally, the housing 210 is the middle frame of the electronic device. The housing 210 comprises a first side 210a and a second side 210b arranged opposite to each other, and has a spacing region 210c between the first side 210a and the second side 210b. The driving assembly 230 is arranged in the spacing region 210c, and the driving assembly 230 is connected with the first side 210a and the second side 210b.

[0082] The driving assembly 230 comprises a driving part 231, a movable part 232, and a bracket 233. The driving part 231 is connected with the housing 210. For example, the bracket 233 is connected with the housing 210, and the driving part 231 is mounted on the bracket 233. The movable part 232 is in transmission connection with the driving part 231, and the movable part 232 is movable relative to the driving part 231. In this way, the movable part 232 has a movement stroke away from or towards the housing 210 under the driving action of the driving part 231.

[0083] Optionally, Figure 4 is a schematic view of the structure of the driving assembly 230 according to an example embodiment. As shown in Figure 4 The driving part 231 comprises a driving assembly 231A, a speed reducer 231B, and a transmission member 231C.

[0084] The driving assembly 231A comprises at least one driving motor 2311 and a circuit board 2312 electrically connected with the driving motor 2311. The circuit board 2312 is used to electrically connect the driving motor 2311 with a control assembly (for example, a control chip) to realize controllable setting of the driving motor 2311. The driving motor 2311 can be a direct current stepper motor. At this time, the driving motor 2311 converts an electric pulse signal into an angular displacement or a linear displacement. At this time, the driving motor 2311 is controlled to rotate by a fixed angle in a set direction through a pulse signal, and the angular displacement amount is controlled by controlling the pulse number, so that the purpose of accurate positioning is achieved. Meanwhile, the rotating speed and acceleration of the driving motor 2311 are controlled by controlling the pulse frequency, so that the purpose of speed regulation is achieved, and the rotating torque is input.

[0085] The speed reducer 231B is connected with the driving assembly 231A, and is alternatively fixedly connected with an output shaft of the driving motor 2311. The speed reducer 231B is further connected with the transmission member 231C, and is used to realize rotation of the transmission member 231C at a rotating speed lower than that directly output by the driving assembly 231A. Alternatively, the speed reducer 231B comprises a first speed reduction unit 2313 and a second speed reduction unit 2314 in meshing connection. Two-stage speed reduction is realized through the first speed reduction unit 2313 and the second speed reduction unit 2314, so as to convert low torque of the driving assembly 231A into high torque.

[0086] Figure 5 It is an exploded view of the first speed reduction unit in the speed reducer according to an exemplary embodiment. As shown in Figure 5 The first speed reduction unit 2313 comprises a fixing member 2315, a motor tooth 2316 and a speed reduction gear assembly 2317 installed in the fixing member 2315.

[0087] On the basis of Figure 5 in combination with Figure 4 The fixing member 2315 comprises but is not limited to a solid gear ring, and the solid gear ring forms an outer housing of the first speed reduction unit 2313. One end of the motor tooth 2316 is fixedly connected with the driving motor 2311, and the other end is provided with a transmission tooth in meshing connection with the speed reduction gear assembly 2317. The speed reduction gear assembly 2317 is a core component of the first speed reduction unit 2313, and is used to realize the function of rotation adjustment. In the embodiment of the present disclosure, the speed reduction gear assembly 2317 comprises but is not limited to at least one planetary gear. Furthermore, the speed reduction gear assembly 2317 is further connected with the second speed reduction unit 2314. In addition, a bushing is arranged between the motor tooth 2316 and the driving motor 2311, and a bushing is arranged between the speed reduction gear assembly 2317 and the second speed reduction unit 2314.

[0088] In this way, the driving motor 231A drives the motor gear 2316 to rotate, the motor gear 2316 drives the reduction gear assembly 2317 to rotate, and the reduction gear assembly 2317 drives the second reduction unit 2314 to rotate, and the driving member 231C is driven.

[0089] Continuing to refer to Figure 4 , the driving member 231C is connected with the reduction member 231B and is used to drive the movable part 232. Optionally, the driving member 231C is a screw rod engaged with the reduction member 231B, and the driving member 231C is rotatably connected with the support 233. In this case, the reduction member 231B is driven to rotate relative to the support 233 by the driving member 231C. At this time, the movable part 232 is sleeved on the driving member 231C and is threadedly connected with the driving member 231C. In addition, the driving assembly 230 further comprises a guide part 234 arranged in parallel with the driving member 231C, and the movable part 232 is also sleeved on the guide part 234. The guide part 234 defines the linear movement of the movable part 232 along the guide part 234, and thus the linear movement of the movable member 220A is realized.

[0090] Continuing to refer to Figure 3 , the movable member 220A is connected with the movable part 232 in the driving assembly 230. Figure 6 is a partial sectional view of the housing and the movable member according to an exemplary embodiment. As shown in Figure 6 , the movable member 220A is provided with a slot 225, and the movable part 232 is inserted into the slot 225. In this way, the movable member 220A and the movable part 232 keep synchronous linear movement.

[0091] In addition, the movable member 220A is also connected with the flexible display screen 100, for example, is directly connected with the flexible display screen 100, or is connected through other mechanisms. The movable member 220A is used to drive the second end 120 of the flexible display screen 100 to move away from or close to the first end 110 of the flexible display screen 100 by the driving assembly 230.

[0092] The movable member 220A abuts against the part of the flexible display screen 100 corresponding to the side surface 130 of the electronic device. In addition, the movable member 220A is connected with the second end 120 of the flexible display screen 100. For example, the movable member 220A is directly connected with the second end 120 of the flexible display screen 100. Alternatively, the electronic device further comprises a telescopic auxiliary mechanism. The telescopic auxiliary mechanism is connected with the movable member 220A and is movably connected with the second end 120 of the flexible display screen 100. The telescopic auxiliary mechanism is provided with an elastic member, and when the second end 120 moves away from the first end 110, the elastic member is stretched to apply a retracting force to the second end 120.

[0093] In this way, when the movable member 220A is driven by the driving assembly 230 to drive the second end 120 of the flexible display 100 away from the first end 110 of the flexible display 100, the flexible display 100 is in the stretched state. When the movable member 220A is driven by the driving assembly 230 to drive the second end 120 of the flexible display 100 close to the first end 110 of the flexible display 100, the flexible display 100 is in the retracted state. Accordingly, the stretching and retraction of the flexible display 100 are achieved by the telescopic driving mechanism, and different use states of the electronic device are switched.

[0094] Figure 7a and Figure 7b are sectional views of the electronic device according to different exemplary embodiments. As shown in Figure 7a and Figure 7b , the housing 210 is fixedly connected with the first end 110 of the flexible display 100. For example, the first end 110 is fixed on the support portion 211 of the housing 210 by a screen pressing edge strip. Figure 8 is a motion flowchart of the driving assembly according to an exemplary embodiment.

[0095] The driving assembly 230 is also electrically connected with a processor in the electronic device through a circuit board. In combination with Figure 7a , Figure 7b and Figure 8 , the driving assembly 230 is driven by the driving assembly 231A as the main body, and the motion process of the driving assembly 230 is as follows:

[0096] Step S801, receiving the state switching instruction sent by the processor.

[0097] The state switching instruction includes an extension instruction for switching to the stretched state, and a retraction instruction for switching to the retracted state.

[0098] Step S802, driving the driving motor to rotate according to the state switching instruction to drive the movable member to move relative to the housing.

[0099] When the extension instruction is received, the control chip in the driving assembly 231A controls the driving motor 2311 to rotate in the first direction. Then, the driving motor 2311 drives the transmission member 231C to rotate through the speed reducer 231B. At this time, the movable portion 232 has a motion trend of rotating and linearly moving relative to the transmission member 231C under the action of the rotation of the transmission member 231C. Moreover, the movable portion 232 is sleeved on the guide portion 234, which limits the circular motion of the movable portion 232. Furthermore, the movable portion 232 presents a positive linear motion along the transmission member 231C to drive the movable member 220A away from the housing 210.

[0100] In combination with Figure 7aThe driving assembly 230 drives the movable member 220A to apply an outward stretching force to the portion of the flexible display 100 corresponding to the side surface 130. The second end 120 of the flexible display 100 moves away from the first end 110 to increase the size of the flexible display 100 on the front surface 110 of the electronic device, achieving the stretched mode.

[0101] When the retracting instruction is received, the control chip in the driving assembly 231A controls the driving motor 2311 to rotate in a second direction opposite to the first direction. In turn, the driving motor 2311 drives the transmission member 231C to rotate through the speed reducer 231B. At this time, under the joint action of the transmission member 231C and the guide part 234, the movable part 232 moves linearly in the opposite direction along the transmission member 231C to drive the movable member 220A to approach the housing 210.

[0102] In combination with Figure 7b The driving assembly 230 drives the movable member 220A to apply an inward retracting force to the portion of the flexible display 100 corresponding to the side surface 130. At this time, the second end 120 of the flexible display 100 moves towards the first end 110 to reduce the size of the flexible display 100 on the front surface 110 of the electronic device, achieving the retracted mode.

[0103] In addition, in an embodiment, the telescopic driving mechanism further includes a distance detection assembly. The distance detection assembly includes an emitting member 241 and a receiving member 242. One of the emitting member 241 and the receiving member 242 is arranged on the housing 210, and the other is arranged on the movable member 220A. Accordingly, the distance detection assembly can detect the distance between the housing 210 and the movable member 220A to determine the telescopic state of the flexible display 100. The distance detection assembly includes, but is not limited to, an optical distance detection assembly (such as an infrared distance sensor) and a magnetic field detection assembly (such as a Hall sensor).

[0104] During the switching of the electronic device to the stretched mode, in response to the distance detection assembly detecting that the distance between the housing 210 and the movable member 220A reaches a first set threshold, the electronic device control chip controls the driving motor 2311 to stop. By stopping, further stretching of the flexible display 100 by the movable member 220A is avoided to ensure the structural safety of the flexible display 100.

[0105] During the switching of the electronic device to the retracted mode, in response to the distance detection assembly detecting that the distance between the housing 210 and the movable member 220A reaches a second set threshold, the electronic device control chip controls the driving motor 2311 to stop. By stopping, further approaching of the housing 210 by the movable member 220A is avoided to ensure the structural safety of the electronic device.

[0106] In one embodiment, the housing 210 is fixedly connected with the first end 110 of the flexible display 100. Optionally, the housing 210 comprises a support portion 211 and a side edge 212 connected with the support portion 211. In this way, the side edge 211 forms the outer edge of the electronic device, and the support portion 211 is located inside the electronic device for carrying or mounting functional modules in the electronic device. For example Figure 1 As shown, the support portion 211 has a rectangular plate structure, and the side edge 212 is arranged around three edges of the support portion 211.

[0107] Figure 9 is a structural schematic diagram of a housing and a movable member according to an exemplary embodiment. As shown Figure 9 The movable member 220A comprises an arc-shaped side portion 221 for abutting the flexible display 100. By abutting the flexible display 100 through the arc-shaped side portion 221, on the one hand, it is convenient for the flexible display 100 to slide relative to the movable member 220A, and on the other hand, it protects the structural safety of the flexible display 100.

[0108] Further, a first transmission member 222 is arranged on the arc-shaped side portion 221, and the first transmission member 222 is rollingly connected with the flexible display 100. By rollingly connecting, the friction between the flexible display 100 and the movable member 220A is further reduced. Optionally, the first transmission member 222 is a ball connecting member arranged on the arc-shaped side portion 221, and the ball of the first transmission member 222 directly contacts the flexible display. The number of the first transmission member 222 is not specifically limited, for example, 2, 3, 4, etc. When at least two first transmission members 222 are arranged on the arc-shaped side portion 221, the at least two first transmission members 222 are uniformly distributed along the length direction of the arc-shaped side portion 221.

[0109] Optionally, referring again to Figure 3 The housing 210 further comprises a guide member 213 connected with the first edge 210a and the second edge 210b. The movable member 220A comprises a connecting portion 223 arranged on the arc-shaped side portion 221. The guide member 213 is movably connected with the connecting portion 223, for limiting the movement of the movable member 220A along the guide member 213. Figure 10 is a partial sectional view of a housing and a movable member according to another exemplary embodiment. In combination with Figure 10 A slot 224 is arranged along the length direction of the connecting portion 223, and the guide member 213 is clamped in the slot, thereby realizing the movable connection between the movable member 220A and the housing 210.

[0110] The structure of the second, stretchable elastic member 220B.

[0111] Figure 11 is a sectional view of a stretchable elastic member in an electronic device according to an exemplary embodiment, Figure 12ais an exploded view of the telescopic elastic member according to an exemplary embodiment, Figure 12b is a schematic view of the telescopic elastic member according to an exemplary embodiment.

[0112] As shown in Figure 11 , the telescopic elastic member 220B is disposed in the electronic device. And, in combination with Figure 12a and Figure 12b , the telescopic elastic member comprises a sliding member 241, a bracket 242 and an elastic member 243.

[0113] The sliding member 241 is connected with the flexible display screen 100 located at the back of the electronic device. For example, an adhesive is disposed on the sliding member 241, and the sliding member 241 is connected with the side of the flexible display screen 100 facing the inside of the electronic device through the adhesive. In this case, when the flexible display screen 100 is moved from the back of the electronic device to the front of the electronic device, the flexible display screen 100 exerts a force on the sliding member 241 towards the side.

[0114] The bracket 242 is in sliding connection with the sliding member 241, specifically, the bracket 242 and the sliding member 241 slide relative to each other in a direction perpendicular to the side of the electronic device. The bracket 242 is connected with the movable member 120A, and accordingly, the bracket 242 and the sliding member 241 move relative to each other as the movable member 120A moves relative to the housing 110. For example, referring to Figure 12a and Figure 12b , a guide member 245 is further disposed on the bracket 242, and the guide member 245 is in movable connection with the sliding member 241 to enable the sliding member 242 to slide along the guide member 245. Accordingly, the stable movement of the sliding member 242 relative to the bracket 242 is ensured.

[0115] The guide member 245 is connected with the bracket 242 through a fastener, or the guide member 245 is integrally formed with the bracket 242. The guide member 245 is made of POM (Polyoxymetylene, polyoxymethylene), which has a self-lubricating function, and the use of this material for the guide member 245 can reduce the friction between the guide member 245 and the sliding member 241.

[0116] A guide groove 2421 is disposed on the sliding member 242 to cooperate with the guide member 245. For example, Figure 12b , the guide member 245 is provided with the guide groove 2421 which is open to the side. The guide groove 2421 is used to insert the guide member 245. In the embodiments of the present disclosure, the arrangement of the guide groove 2421 is not limited, as long as it can cooperate with the guide member 2421. Of course, a protruding key can also be disposed on the sliding member 241, and a guide groove which cooperates with the protruding key is disposed on the guide member 245, and the guide groove is used to insert the protruding key.

[0117] Figure 13a and Figure 13b are schematic diagrams of different use states of the telescopic elastic member according to an exemplary embodiment. In Figure 10 , in combination with Figure 13a and Figure 13b , the slider 241 can move towards or away from the bracket 242 along the X axis. Moreover, the bracket 242 is arranged between the slider 241 and the side surface of the electronic device. In such a case, when the slider 241 is acted on by the flexible display 100, it can slide towards the bracket 242.

[0118] The bracket 242 is used to bear an external force and drive an acting force towards the side surface of the electronic device on the flexible display 100. A driving mechanism 230 is arranged in the electronic device, which is connected with the bracket 242 in the telescopic elastic member and is used to drive the bracket 242 to move towards or away from the side surface. Moreover, the movable member 220A also abuts against the part of the flexible display 100 corresponding to the side surface and is fixedly connected with the bracket 242 in the telescopic elastic member 220B.

[0119] In such a case, in combination with Figure 13a , the bracket 242 is driven by the driving assembly 230 to drive the movable member 220A to exert a pushing force along the positive direction of the X axis on the flexible display 100. Further, since the part of the flexible display 100 located on the front surface of the electronic device is fixed, under the action of the pushing force exerted by the bracket 242, the flexible display 100 has a movement trend of moving from the back surface to the front surface. In such a case, the flexible display 100 exerts an acting force along the positive direction of the X axis on the slider 241, thereby driving the slider 241 to move close to the bracket 242. At this time, one end of the flexible display 100 located on the back surface of the electronic device moves towards the side surface, so that the flexible display on the back surface is turned to the front surface, thereby expanding the size of the flexible display on the front surface of the electronic device.

[0120] The elastic member 243 includes a first end 2431 and a second end 2432. The first end 2431 is connected with the slider 241, and the second end 2432 is fixedly connected with the bracket 242. In this way, the elastic member 243 deforms with the relative movement of the slider 241 and the bracket 242. Moreover, the elastic member 243 is used to exert an acting force (i.e., an acting force along the negative direction of the X axis) on the slider 241 away from the side surface, so as to drive the slider 241 to move away from the bracket 242 (as shown in Figure 12b By driving the slider 241 to move away from the bracket 242 by the elastic member 243, the slider 241 drives the flexible display 100 to turn from the front surface of the electronic device to the back surface of the electronic device, thereby reducing the size of the flexible display 100 on the front surface of the electronic device.

[0121] In the embodiments of the present disclosure, the elastic member 243 has two setting modes, which are described as follows.

[0122] <First mode>

[0123] Figure 14 is a structural schematic diagram of the telescopic elastic member according to another exemplary embodiment. As shown in Figure 14 , the elastic member 243 is arranged between the sliding member 241 and the bracket 242, with the first end 2431 connected to the sliding member 241 and the second end 2432 directly connected to the bracket 242.

[0124] When the sliding member 241 is driven by the flexible display 100 to move close to the bracket 242, the elastic member 243 is in a compressed state and exerts a force on the sliding member 241 in the reverse direction of the X axis. Meanwhile, the flexible display 100 exerts a force on the sliding member 241 in the forward direction of the X axis under the action of the bracket 242 driven by the driving mechanism 230. Based on the combined action of the flexible display 100 and the elastic member 243, the sliding member 241 is in a stable state of rest.

[0125] When the driving mechanism 230 drives the bracket 242 to retract, that is, drives the bracket 242 to move in the reverse direction of the X axis, the force exerted by the flexible display 100 on the sliding member 241 in the forward direction of the X axis is weakened. At this time, the elastic member 243 has a tendency to move out and can drive the sliding member 241 to move away from the bracket 242. Further, the sliding member 241 drives the flexible display 100 to flip from the front face of the electronic device to the back face of the electronic device, so that the size of the flexible display 100 on the front face of the electronic device is reduced.

[0126] <Second mode>

[0127] Figure 15a is a sectional view of the telescopic elastic member according to Figure 13a , and Figure 15b is a sectional view of the telescopic elastic member according to Figure 13b . As shown in Figure 15a and Figure 15b , the first end 2431 of the elastic member 243 and the sliding member 241 are arranged on the same side of the bracket 242, and the first end 2431 is kept at a certain distance from the bracket 242. At this time, the elastic member 243 is used to exert a force on the sliding member 241 under tension.

[0128] Optionally, the bracket 242 is provided with a mounting member 244, which includes an extension part 2441 and a mounting part 2442. The extension part 2441 is connected to the bracket 242 and extends to the side of the sliding member 241. The mounting part 2442 is connected to the part of the extension part 2441 away from the bracket 242, and the mounting part 2442 is used to mount the second end 2432 of the elastic member 243. In this way, the first end 2431 of the elastic member 243 is kept at a certain distance from the bracket 242 by the extension part 2441.

[0129] In combination Figure 15a and Figure 13a When the slider 241 is driven by the flexible display 100 to move close to the support 241, the elastic member 243 is in a retracted state. At this time, the elastic member 243 applies a force in the reverse direction of the X-axis to the slider 241. Meanwhile, the flexible display 100 applies a force in the positive direction of the X-axis to the slider 241 under the action of the support 242 driven by the driving mechanism 230. Based on the combined action of the flexible display 100 and the elastic member 243, the slider 241 is in a stable state of rest.

[0130] In combination Figure 15b and Figure 13b When the driving mechanism 230 drives the support 242 to retract, i.e., to move in the reverse direction of the X-axis, the force in the positive direction of the X-axis applied by the flexible display 100 to the slider 241 is weakened. At this time, the elastic member 243 has a tendency to retract and can drive the slider 241 to move away from the support 242. Further, the slider 241 drives the flexible display 100 to flip from the front side of the electronic device to the back side of the electronic device, so that the size of the flexible display 100 on the front side of the electronic device is reduced.

[0131] Further, the embodiment of the present disclosure provides an implementation of a mounting member.

[0132] Figure 16 is a structural schematic diagram of a mounting member in a retractable elastic member according to an exemplary embodiment. As shown in Figure 16 The mounting portion 2442 includes a side wall 2442a connected to the extension portion 2441, and the side wall 2442a extends towards the front side of the electronic device. Optionally, the mounting portion 2442 includes oppositely arranged side walls 2442a, and a top wall 2442b connected to the side walls 2442a. Among them, a part of the top wall 2442b is connected to the top of the side wall 2442a (i.e., the part of the side wall 2441a close to the front side), and another part of the top wall 2442b is inclined to the back side of the electronic device and extends downwardly to connect with the extension portion 2441.

[0133] In this way, the mounting portion 2442 forms a cavity protruding towards the front side of the electronic device, and the elastic member 243 is installed in the cavity. In this way, the structural safety of the elastic member 243 is ensured by the mounting portion 2442.

[0134] And, the support 2442c is arranged on the sidewall 2442a and parallel to the front surface of the electronic device. The second end 2432 of the elastic member 243 is connected to the support 2442c, and the elastic member 243 is wound on the support 2442c. When the sliding member 241 is extended and retracted, the elastic member 243 rotates around the support 2442c. In other words, the elastic member 243 is a spring wound on the support 2442c. Optionally, the thickness of the spring is 0.03mm-1mm. Optionally, the elastic member 243 is a volute spring.

[0135] In this way, the space occupied by the elastic member 243 is reduced, and the part of the elastic member 243 that is extended and retracted is in the form of a sheet with a small thickness and occupies a small space. In this way, on the one hand, the influence of the elastic member 243 on other components in the extension and retraction elastic member is reduced, and on the other hand, the volume of the overall extension and retraction auxiliary mechanism is reduced, facilitating the arrangement of the mechanism in the electronic device.

[0136] Optionally, referring to Figure 11 The bracket 242 is provided with at least two mounting members 244, and the elastic member 243 is arranged in each mounting member 244. For example, the two ends of the bracket 242 are provided with two mounting members 244. In this way, the elastic members 243 in the two mounting members 244 apply a stable force to the sliding member 241, ensuring that the sliding member 241 moves stably relative to the bracket 242.

[0137] Optionally, the elastic member 243 is a constant force spring. After the deformation stroke of the constant force spring reaches a set value, the elastic force of the constant force spring remains constant as the deformation stroke increases. In this way, as the sliding member 241 continuously approaches the bracket 242, the elastic member 243 applies a constant pulling force to the sliding member 241 when the extension and retraction stroke of the elastic member 243 exceeds the set value. At this time, the driving burden of the flexible display 100 on the sliding member 241 can be reduced, and the driving burden of the driving mechanism 230 on the flexible display 100 through the bracket 242 can be reduced.

[0138] Based on the above, the overall scheme of the extension and retraction driving mechanism 200 provided by the embodiment of the present disclosure is described:

[0139] Figure 17a And Figure 17b are different morphological schematic diagrams of the extension and retraction driving mechanism according to an exemplary embodiment. As shown in Figure 17a and Figure 17b In the extension and retraction driving mechanism 200, the extension and retraction elastic mechanism 220B is mounted on the movable member 220A. For example, the bracket 242 of the extension and retraction elastic mechanism 220B is connected to the movable member 220A by a fastener. The working process of the extension and retraction driving mechanism 200 is as follows:

[0140] In combination with Figure 7a and Figure 17a The process of switching the telescopic driving mechanism 200 to the stretched state is as follows:

[0141] The driving assembly 230 drives the movable member 220A to move away from the housing 210, so as to drive the bracket 242 connected to the movable member 220A to apply a force to the flexible display 100 in the direction of the side surface. Accordingly, the flexible display 100 applies a pulling force to the sliding member 241. At this time, the sliding member 241 moves in the direction of approaching the bracket 242, so that the flexible display 100 is flipped from the back surface of the electronic device to the front surface of the electronic device. Moreover, in the process of the sliding member 241 approaching the bracket 242, the elastic member 243 applies a force to the sliding member 241 in the direction of moving away from the bracket 242.

[0142] In combination with Figure 7b and Figure 17b The process of switching the telescopic driving mechanism 200 to the retracted state is as follows:

[0143] The driving assembly 230 drives the movable member 220A to move close to the housing 210, so as to drive the bracket 242 connected to the movable member 220A to move in the direction of moving away from the side surface, so that the force applied by the bracket 242 to the flexible display 100 is weakened. At this time, the sliding member 241 is driven to move away from the bracket 242 under the action of the elastic member 243. Further, the sliding member 241 drives the flexible display 100 to flip from the front surface of the electronic device to the back surface.

[0144] In one embodiment, the electronic device provided by the embodiments of the present disclosure further comprises a protective shell. The protective shell makes the internal structure of the electronic device not exposed in the stretched state, and ensures the structural safety of the overall electronic device.

[0145] Figure 18 is a structural schematic diagram of an electronic device according to another exemplary embodiment, Figure 19a and Figure 19b are structural schematic diagrams of different states of a protective shell according to an exemplary embodiment.

[0146] As shown in Figure 18 , the electronic device provided by the embodiments of the present disclosure further comprises a protective shell 300. The protective shell 300 is arranged on the back surface of the electronic device, and specifically comprises a fixed part 310 and a movable part 320.

[0147] The fixed part 310 is connected with the shell 210. The movable part 320 is arranged on the side of the fixed part 310 facing the inside of the electronic device or the side facing the outside of the electronic device. The movable part 320 is movably connected with the fixed part 310. The movable part 320 is also used to be connected with the movable component 220A in the electronic device. Further, as the movable component 220A moves relative to the shell 210, the movable part 320 moves away from or approaches the fixed part 310.

[0148] When the movable component 220A moves away from the shell 210, the movable component 220A drives the movable part 320 to move away from the fixed part 310. At this time, as shown in Figure 19a , the overall length of the protective shell 300 increases to adapt to the stretched state of the electronic device.

[0149] When the movable component 220A approaches the shell 210, the movable component 220A drives the movable part 320 to approach the fixed part 310. At this time, as shown in Figure 19b , the overall length of the protective shell 300 decreases to adapt to the retracted state of the electronic device.

[0150] In this way, the protective shell 300 provides comprehensive protection in different use states of the electronic device, avoids exposure of internal components of the electronic device, and ensures the structural safety and use safety of the overall electronic device.

[0151] In an embodiment, in the state where the displacement of the movable part 320 relative to the fixed part 310 is the largest, part of the movable part 320 overlaps part of the fixed part 330. In other words, in the stretched state, the movable part 320 and the fixed part 310 have overlapping parts. In this way, the protection effect of the protective shell is optimized, and exposure of internal components of the electronic device in the stretched state is avoided, ensuring the safety of the electronic device.

[0152] In the embodiments of the present disclosure, the fixed part 310 and the movable part 320 are arranged in layers. With reference to the inside-outside direction of the electronic device, the fixed part 310 is arranged outside the movable part 320 in the following description and the accompanying drawings. Of course, the fixed part 310 can also be arranged inside the movable part 320 according to actual requirements.

[0153] Figure 20 is another angle structure schematic diagram of the protective shell according to an exemplary embodiment. Referring to Figure 18 and Figure 20 , the fixed part 310 includes a first main body 311 and a first side part 312.

[0154] The first body 311 has a plate structure, and the first side portion 312 is connected to the edge of the first body 311 and extends in a direction perpendicular to the first body 311. Moreover, the first side portion 312 is arranged on two opposite edges of the first body 311. The first body 311 is arranged to correspond to the back of the electronic device, and the first side portion 312 is arranged to correspond to at least one side of the electronic device. In this way, the fixing portion 310 covers the back and the side of the electronic device.

[0155] Optionally, the first side portion 312 is provided with a mounting position for mounting a fastener or an adhesive member to connect the fixing portion 310 and the shell 210. In this way, the fixing portion 310 and the shell 210 are relatively stable.

[0156] The movable portion 320 has a structure similar to the fixing portion 310. Referring to Figure 18 and Figure 20 , the movable portion 320 includes a second body 321 and a second side portion 322.

[0157] The second body 321 has a plate structure, and the second side portion 322 is connected to the edge of the second body 321 and extends in a direction perpendicular to the second body 321. Moreover, the second side portion 322 is arranged on two opposite edges of the second body 321. The second body 321 is arranged to correspond to the first body 311 of the fixing portion 310. The second side portion 322 is arranged to correspond to at least one side of the electronic device.

[0158] Moreover, the second side portion 322 is provided with a mounting position for mounting a fastener or an adhesive member to connect the movable portion 320 and the movable member 220A. In this way, the movable portion 320 and the movable member 220A are relatively stable.

[0159] Based on the above, when the movable member 220A moves relative to the shell 210, the fixing portion 310 and the movable portion 320 move linearly relative to each other.

[0160] Figure 21a and Figure 21b are schematic diagrams of different use modes of the electronic device according to an exemplary embodiment. The movable portion 320 is arranged inside the fixing portion 310. As shown in Figure 21a , in the retracted mode, the movable portion 320 is retracted inside the fixing portion 310. At this time, the movable portion 320 cannot be observed from the outside of the electronic device. As shown in Figure 21b , in the stretched mode, the movable portion 320 is stretched from the inside of the fixing portion 310. At this time, the second side portion 322 of the movable portion 320 is arranged to correspond to the side of the electronic device that is stretched, and is partially offset from the first side portion 312 of the fixing portion 310.

[0161] In this way, the active part 320 and the fixed part 310 provide comprehensive protection for the back and side of the electronic device.

[0162] In addition, the first clamping edge 313 is arranged on the portion of the first side part 312 away from the first main body 311. The first clamping edge 313 is parallel to the first main body 311 and is arranged above the display screen of the electronic device. For example, the first clamping edge 313 has a gap with the display screen with a width of 0.05-0.3 mm. The gap provides a deformation space for the display screen, and the range of the gap avoids the display screen from being wrinkled in the stretched state.

[0163] In addition, the second clamping edge 323 is arranged on the portion of the second side part 322 away from the second main body 321. The second clamping edge 323 is parallel to the second main body 321 and is arranged above the display screen of the electronic device. For example, the second clamping edge 323 has a gap with the display screen with a width of 0.05-0.3 mm. The gap provides a deformation space for the display screen, and the range of the gap avoids the display screen from being wrinkled in the stretched state and the retracted state.

[0164] Figure 22 is a cross-sectional view of the protective shell according to an example embodiment. As shown in Figure 22 The first clamping edge 313 of the fixed part 310 has a guide groove 314. The second clamping edge 323 of the active part 320 is inserted into the guide groove 314. In addition, the active part 320 moves along the length direction of the guide groove 314 relative to the fixed part 310. The guide groove 314 plays a guiding role, improving the stability of the relative movement of the active part 320 and the fixed part 310.

[0165] Optionally, the first clamping edge 313 includes a first extension part 313a, a bending part 313b and a second extension part 313c connected in sequence. The first extension part 313a is connected to the first side part 312 at the end away from the bending part 313b. The bending direction of the bending part 313b is configured to be opposite to the extension direction of the first extension part 313a and the second extension part 313c. At this time, the space between the first extension part 313a and the second extension part 313v forms the guide groove 314. In addition, the opening of the guide groove 314 faces the first side part 312. The second clamping edge 323 extends into the guide groove 314 through the opening of the guide groove 314, thereby realizing the sliding connection between the second clamping edge 323 and the guide groove 314.

[0166] In one embodiment, referring to Figure 21b and Figure 22A reinforcing rib 320a is arranged on the movable part 320. The structural strength of the movable part 320 is optimized by the reinforcing rib 320a, and the mechanical stability of the overall protective shell is improved. The distribution of the reinforcing rib 320a is not limited, for example, the reinforcing rib 320a is arranged on the second main body 321 or the second side part 322. The number of reinforcing ribs 320a is not limited, for example, 2, 3, 4, etc.

[0167] Optionally, the reinforcing rib 320a protrudes towards the fixed part 310 and is in contact with the fixed part 310. For example, the reinforcing rib 320a arranged on the second main body 321 protrudes towards the first main body 311 and is in contact with the first main body 311. The reinforcing rib 320a arranged on the second side part 322 protrudes towards the first side part 312 and is in contact with the first side part 312. In this way, the movable part 320 is in contact with the fixed part 310 only at the reinforcing rib 320a, which reduces the sliding resistance when the movable part 320 and the fixed part 310 move relative to each other, so that the protective shell can smoothly switch between the stretched state and the retracted state.

[0168] In one embodiment, continuing to refer to Figure 18 In the movable part 320, a recessed area 321a is arranged at the edge of the second main body 321 away from the shell 210. In the electronic device, the display screen below the movable part 320 is exposed through the recessed area 321a, so that the side of the electronic device is covered by the display screen, thereby optimizing the display effect of the display screen.

[0169] In summary, the protective shell 300 uses the fixed part 310 and the movable part 320 connected by the hinge to adapt to the stretched state and the retracted state of the electronic device. It provides effective protection in different states of the electronic device, avoids exposing the internal structure of the electronic device, and optimizes the structural safety and use experience of the overall device.

[0170] The electronic device provided by the embodiments of the present disclosure further includes a display screen support mechanism. The display screen support mechanism is arranged below the flexible display screen 100 and is used to support the flexible display screen 100 located on the front of the electronic device.

[0171] Figure 23a And Figure 23b are structural schematic diagrams of the display screen support mechanism in different states according to an exemplary embodiment. As shown in Figure 23a And Figure 23b The display screen support mechanism 400 is arranged below the flexible display screen 100 and is used to support the flexible display screen 100. Specifically, the display screen support mechanism 400 includes a fixed support 410 and a movable support 420.

[0172] Figure 24is an assembly schematic diagram of the display screen support mechanism in the electronic device according to an exemplary embodiment. As shown in Figure 24 The fixed support 410 is configured to be connected to the housing 210. The movable support 420 is configured to be connected to the movable component 220A. A guide groove 430 is provided on one of the fixed support 410 and the movable support 420, and a guide rail 440 is provided on the other one of the fixed support 410 and the movable support 420. The fixed support 410 and the movable support 420 are movably connected through the guide groove 430 and the guide rail 440.

[0173] In this way, as the movable component 220A moves relative to the housing 210, the fixed support 410 and the movable support 420 are driven to move relative to each other. Specifically, as shown in Figure 23a When the electronic device is in the stretched state, the movable component 220A is away from the housing 210, and the movable support 420 is driven to move away from the fixed support 410. As shown in Figure 23b When the electronic device is in the retracted state, the movable component 220A is close to the housing 210, and the movable support 420 is driven to move close to the fixed support 410.

[0174] In this way, the display screen support mechanism 400 can adapt to the stretched state and the retracted state of the electronic device, and can provide effective support for the flexible display screen 100 in both the stretched state and the retracted state of the electronic device.

[0175] In the embodiments of the present disclosure, the arrangement of the guide rail and the guide groove is not limited, and in the drawings, only the arrangement of the guide groove 430 on the fixed support 410 and the guide rail 440 on the movable support 420 is taken as an example.

[0176] In one embodiment, the fixed support 410 includes a fixed part 411 and at least two guide parts 412 connected to the fixed part 411. For example, the guide part 412 is connected to one edge of the fixed part 411 and extends away from the fixed part 411. The fixed part 411 is configured to be connected to the housing in the electronic device. The guide groove 430 is provided on the guide part 412 and is configured to be inserted into the guide rail 440 of the movable support 420.

[0177] The movable support 420 includes a connecting part 421 and at least two guide rails 440 connected to the connecting part 421. The guide rail 440 is connected to one edge of the connecting part 421 and extends away from the connecting part 421. The connecting part 421 is configured to be connected to the movable component in the electronic device. Accordingly, the movable support 420 and the fixed support 410 can move synchronously with the relative movement of the housing and the movable component.

[0178] The embodiments of the present disclosure provide two different arrangements of the guide groove 430, Figure 25a and Figure 25b are structural schematic diagrams of the guide groove according to different exemplary embodiments.

[0179] <First way>

[0180] As shown in Figure 25a , the guide part 412 has a hollow rod structure, and the hollow part of the guide part 412 forms a guide groove 430. At this time, the inner wall of the guide groove 430 forms a limiting part 431 to limit the guide rail 440 in the direction perpendicular to the length direction of the guide groove 430. In this way, the guide groove 430 fully protects the structure safety of the guide rail 440. In this scheme, the radial cross-sectional shape of the guide groove 430 is not specifically limited, such as rectangular, circular, etc.

[0181] <Second way>

[0182] As shown in Figure 25b and in combination with Figure 23a , the guide groove 430 forms an opening 432 on the guide part 412, and the opening 432 is distributed along the length direction of the guide groove 430. When the guide rail 414 is inserted into the guide groove 430, the opening 432 is exposed outside the guide groove 430. And the surface of the guide rail 414 exposed outside the guide groove 430 is flush with the surface of the guide part 412 around the opening 431. Accordingly, the plane formed by the guide rail 414 and the guide part 412 can smoothly support the flexible display screen 100.

[0183] In this way, the processing difficulty of the overall support mechanism can be reduced. Especially in the case where the thickness of the guide part 412 is thin, it is easier to realize the guide groove 430 with the opening 432.

[0184] Further, the limiting part 431 is arranged on the guide part 412, which is arranged at the edge of the opening 432 of the guide groove 430 and extends transversely towards the opening 432. At this time, the size of the opening 432 is reduced by the limiting part 431. The limiting part 431 is used to limit the guide rail 440 in the guide groove 430 in the direction perpendicular to the length direction of the guide rail, thereby improving the structural stability of the overall support mechanism.

[0185] Optionally, a recessed area 412a is arranged at the edge of the opening 432 of the guide part 412, and the limiting part 431 is installed in the recessed area 412a. Accordingly, the limiting part 431, the guide rail 414 and the outer surface of the guide part 412 are flush, to provide smooth support for the flexible display screen.

[0186] Among them, there are many ways to arrange the limiting part 431:

[0187] Optionally, the limiting part 431 is arranged at one edge of the opening 432. Alternatively, the limiting part 431 is arranged at two opposite edges of the opening 432.

[0188] Optionally, the limiting member 431 is disposed through the guide groove 430 along its length. Alternatively, the display support structure includes a plurality of limiting members 431, which are disposed at intervals along the length of the guide groove 430.

[0189] Furthermore, based on Figure 25b The provided guide groove 430 structure includes a guide rail 440 comprising a first part 441 and a second part 442. The first part 441 and the second part 442 are disposed along the depth direction 1 of the guide groove 430, with the first part 441 relatively close to the opening 432. The second part 442 extends beyond the first part 441 in a direction perpendicular to the depth direction 1 of the guide groove. At this time, the portion of the second part 442 extending beyond the first part 441 corresponds to the limiting member 431. In this manner, through the cooperation of the limiting member 431 and the second part 442, the guide rail 440 will not detach from the guide groove 430, ensuring the structural stability of the overall display screen support mechanism.

[0190] Furthermore, the first part 441 is exposed to the outside of the guide groove 430 through the opening 432, and the outer surfaces of the first part 441, the limiting member 431, and the guide part 412 are flush. Optionally, a gap is provided between the side wall of the limiting member 431 and the side wall of the first part 441. And / or, a gap is provided between the side wall of the guide groove 430 and the side wall of the second part 442. For example, a gap of 0.05 to 0.2 mm is reserved to ensure that the guide rail 440 can slide smoothly along the guide groove 430 and avoid jamming.

[0191] The display support mechanism 400 provided in this embodiment of the present disclosure adapts to the stretched and retracted forms of the electronic device through the relatively movable fixed support part 410 and movable support part 420, thereby providing comprehensive support and protection for the flexible display screen.

[0192] Figure 26a and Figure 26b This is a schematic diagram illustrating a method for fixing a flexible display screen in an electronic device according to an exemplary embodiment. Combining the housing 210, movable member 220, and display screen support mechanism described above, the method for fixing a flexible display screen in an electronic device provided in this disclosure embodiment is as follows:

[0193] like Figure 26a As shown, the flexible display screen located on the front of the electronic device is connected to the fixing part 411 of the fixing support member 410 in the display screen support mechanism. Optionally, the flexible display screen is also connected to two opposite edges of the guide part 412 in the fixing support member 410. This ensures that the overall structure of the flexible display screen is flat.

[0194] like Figure 26bAs shown, the flexible display screen located at the back of the electronic device is connected with the sliding piece 241 in the telescopic elastic mechanism 220B, so that the flexible display screen can drive the sliding piece 241 to slide relative to the support 242, thereby realizing the switching between the stretched mode and the retracted mode of the electronic device.

[0195] In addition, the stacking scheme of the functional modules is not specifically limited in the electronic device provided by the embodiments of the present disclosure. Figure 27 FIG. 1 is a schematic diagram of the internal structure of an electronic device according to an example embodiment, which is described with reference to FIGS. 2-8. Figure 27 The battery 500 is arranged above and below the movable assembly 220 in the electronic device. For example, the electronic device includes two batteries 500 arranged on both sides of the driving motor 2311. The rear camera module 600, the earpiece module 700, the microphone module 800, and the mainboard 900 are arranged in the electronic device corresponding to the first side 210a of the housing 210. The above is only an example scheme, and those skilled in the art can set the stacking scheme of the functional modules according to the needs in combination with the above description.

[0196] Figure 28a FIG. 4 is a schematic diagram of the front of the electronic device in the retracted mode according to an example embodiment, Figure 28b FIG. 5 is a schematic diagram of the back of the electronic device in the retracted mode according to an example embodiment, Figure 28c FIG. 6 is a schematic diagram of the front of the electronic device in the stretched mode according to an example embodiment.

[0197] As shown in FIGS. 4 and 5, Figure 28a and Figure 28b As shown, the size of the display screen located at the front of the electronic device in the retracted mode is relatively small, and the size of the display screen located at the back of the electronic device is relatively large. At this time, the electronic device is suitable for conventional use scenarios, such as communication use scenarios, reading use scenarios, etc.

[0198] As shown in FIGS. 6 and 7, Figure 28b As shown, the size of the display screen located at the front of the electronic device in the stretched mode is increased. At this time, the electronic device is suitable for special use scenarios, such as game use scenarios, movie watching use scenarios, etc.

[0199] In summary, the electronic device provided by the embodiments of the present disclosure can be switched between the stretched mode and the retracted mode to change the size of the display screen on the front of the electronic device, thereby meeting different user needs and optimizing the use experience.
