The electronic device 10 provided in the embodiment of the present application may be a mobile phone, a tablet computer, a notebook computer, and other devices, and the following description will be made with the electronic device 10 as a mobile phone. As shown in fig. 1 to 3, the electronic device 10 may include: the flexible screen comprises a housing 100, a telescopic mechanism 200, a first transmission mechanism 300, a rotating mechanism 400, a sliding mechanism 500, a first power mechanism 600, a second power mechanism 700, a second transmission mechanism 800, a flexible screen 900 and a protective film 1000. The housing 100 may have a receiving space 101, and the telescopic mechanism 200, the first transmission mechanism 300, the rotating mechanism 400, the sliding mechanism 500, the first power mechanism 600, the second power mechanism 700, the second transmission mechanism 800, the flexible screen 900, and the protective film 1000 may be disposed in the receiving space 101. The telescopic mechanism 200 can also extend or retract the accommodating space 101. The first transmission mechanism 300 is connected with the rotating mechanism 400 and the sliding mechanism 500, and is used for driving the rotating mechanism 400 and the sliding mechanism 500 to move. The sliding mechanism 500 is connected to the telescopic mechanism 200, and is used for driving the telescopic mechanism 200 to extend or retract into the accommodating space 101. The first power mechanism 600 is connected to the first transmission mechanism 300 for driving the first transmission mechanism 300 to move.

In this embodiment, the telescopic mechanism 200 and the first transmission mechanism 300 can move synchronously, so as to reduce the probability that the telescopic mechanism 200 pulls the flexible screen 900, reduce the friction between the flexible screen 900 and the telescopic mechanism 200, and improve the service life of the flexible screen 900.

Referring to fig. 4 to 5, fig. 4 is a schematic structural view of the housing 100 in fig. 3, and fig. 5 is an assembled schematic view of the sidewall 120 and the baffle 122 in fig. 4.

The housing 100 may be used to carry and secure various components of the electronic device 10. As shown in fig. 4, the housing 100 may be similar in shape to a "concave" shaped structure, and the housing 100 may include: a bottom wall 110 and a side wall 120. The two opposite sides of the bottom wall 110 are respectively provided with a side wall 120, and the side walls 120 extend in the thickness direction of the bottom wall 110, and form the accommodating space 101 together with the bottom wall 110. The accommodating space 101 may be used for installing electronic devices such as a circuit board, a battery, and a camera in addition to the above-mentioned various mechanisms, so as to implement various functions of the electronic device 10. In the present embodiment, the bottom wall 110 and the side wall 120 may be integrally formed, and the two may be made of plastic, so as to reduce the weight of the electronic device 10. The telescopic mechanism 200 may extend or retract the accommodating space 101 from a side of the bottom wall 110 where the side wall 120 is not provided, to enable the flexible screen 900 and the protective film 1000 to be unfolded or folded. The terms "first," "second," "third," and the like in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature.

As shown in fig. 5, a side of the sidewall 120 exposed in the accommodating space 101 may be provided with a mounting plate 121, and the mounting plate 121 may be used to connect with the above-mentioned various mechanisms to implement the assembly of the above-mentioned mechanisms. Meanwhile, the side wall 120 and the mounting plate 121 can be jointly enclosed to form the accommodating cavity 102, so as to provide a reserved space for mounting the mechanisms. In addition, for ease of assembly, a side of the sidewall 120 facing away from the accommodating space 101 may be provided with a baffle 122. When the various mechanisms within the receiving chamber 102 are installed, the baffle 122 may cover the receiving chamber 102 to close the receiving chamber 102. In this embodiment, the mounting plate 121 may be made of metal to improve the connection strength with the above mechanisms. The baffle 122 may be secured to the sidewall 120 by glue or screws. In some embodiments, the baffles 122 may also be removably snap-connected to the side walls 120 to facilitate subsequent repair or replacement of various mechanisms within the receiving chamber 102.

Referring to fig. 6 to 10, fig. 6 is a schematic cross-sectional view of the electronic device 10 along v-v in fig. 1, fig. 7 is a schematic cross-sectional view of the electronic device 10 along vi-vi in fig. 2, fig. 8 is a schematic structural view of the telescopic mechanism 200 in the retracted state in fig. 6, fig. 9 is a schematic structural view of the telescopic mechanism 200 in the extended state in fig. 7, and fig. 10 is a partially enlarged view at C in fig. 9.

The telescopic mechanism 200 may be disposed in the accommodating space 101, for implementing the expansion or contraction of the flexible screen 900 and the protective film 1000. As shown in fig. 6 to 7, one end of the flexible screen 900 may be connected to an end of the telescopic mechanism 200 protruding from the accommodating space 101. One end of the protective film 1000 may also be connected to an end of the telescopic mechanism 200 extending out of the accommodating space 101, and the protective film 1000 may be located on a side of the telescopic mechanism 200 facing away from the flexible screen 900. Therefore, when the telescopic mechanism 200 extends out of the accommodating space 101, the flexible screen 900 can be unfolded along the first direction X under the driving of the telescopic mechanism 200 to obtain a larger screen display area. When the telescopic mechanism 200 is retracted into the accommodating space 101, the flexible screen 900 can be folded into the accommodating space 101 under the driving of the telescopic mechanism 200, so as to ensure the portability of the electronic device 10. Accordingly, the protection film 1000 may be unfolded or folded along the first direction X in the accommodating space 101 under the driving of the telescopic mechanism 200, so as to cover one side of the telescopic mechanism 200 away from the flexible screen 900, and improve the aesthetic property of the electronic device 10 in the unfolded state while protecting the telescopic mechanism 200. In some embodiments, the protective film 1000 may also be a flexible screen to enable a dual-screen display of the electronic device 10 in the unfolded state. The first direction X may be a direction parallel to the telescoping direction of the telescoping mechanism 200.

As shown in fig. 8 to 9, the telescopic mechanism 200 may include: a plurality of telescopic supports 210, a plurality of moving assemblies 220, and a fixed frame 230. The plurality of groups of telescopic supports 210 can be connected in a sliding manner, and a group of moving assemblies 220 can be arranged on the two groups of telescopic supports 210 in a sliding manner, so that the plurality of groups of telescopic supports 210 can be sequentially unfolded or folded in the first direction X by using the moving assemblies 220, and the telescopic mechanism 200 can be extended or retracted into the accommodating space 101. The fixing frame 230 may be disposed in the accommodating space 101 to provide a guide for the expansion or contraction of the flexible screen 900. In this embodiment, the sliding mechanism 500 may be connected to a set of telescopic brackets 210 located at the end, and the set of telescopic brackets 210 may be located in the accommodating space 101 in the unfolded state, so that when the sliding mechanism 500 slides, the set of telescopic brackets 210 may be driven to slide, and further, the moving assembly 220 is utilized to drive another set of telescopic brackets 210 slidably connected to the set of telescopic brackets 210 to slide, thereby realizing unfolding or folding of the plurality of sets of telescopic brackets 210. One end of the flexible screen 900 may be connected to a set of telescopic brackets 210 at the end, and the set of telescopic brackets 210 is furthest from the housing 100 in the unfolded state, so that the unfolded state of the flexible screen 900 may be maximized, thereby obtaining the maximum screen display area. The other end of the flexible screen 900 may be folded along the fixing frame 230 and then wound around the first transmission mechanism 300, so as to facilitate the accommodation of the flexible screen 900 in the accommodating space 101. Accordingly, one end of the protection film 1000 may be connected to a set of telescopic brackets 210 at the end, and the telescopic brackets 210 are furthest from the housing 100 in the unfolded state, so as to cover a plurality of sets of telescopic brackets 210 at the middle region. In the description of the present application, "plurality of sets" means at least two sets, e.g., two sets, three sets, etc., unless specifically defined otherwise.

The telescoping support 210 may be used to support the flexible screen 900 to maintain the flatness of the flexible screen 900. As shown in fig. 8-9, when multiple sets of telescoping supports 210 are collapsed together, multiple sets of telescoping supports 210 may form a complete plane to support flexible screen 900. When the plurality of sets of telescoping supports 210 are deployed, the plurality of sets of telescoping supports 210 may form a grid-like structure to support the flexible screen 900. So configured, the flexible screen 900 may be supported to ensure a flat display of the flexible screen 900, whether in the expanded state or the collapsed state of the plurality of sets of telescoping supports 210. In addition, when the telescopic mechanism 200 is in the extended state, the telescopic bracket 210 at the end is further provided with a connecting arm 211, which is used for connecting with the sliding mechanism 500, so that the telescopic mechanism 200 can be driven by the sliding mechanism 500 to extend and retract.

The motion assembly 220 may be used to effect the deployment or retraction of multiple sets of telescoping supports 210, which may be provided with a rack 221, two gears 222, and a toothed belt 223. As shown in fig. 10, two gears 222 may be disposed on a set of telescopic brackets 210, and a toothed belt 223 may be sleeved on one tooth portion of the two gears 222 at the same time. The rack 221 may be disposed on another set of telescopic brackets 210 slidably connected to the set of telescopic brackets 210, and the other tooth portion of one gear 222 is engaged. So configured, when the telescopic bracket 210 at the end slides under the driving of the sliding mechanism 500, the plurality of groups of telescopic brackets 210 can be unfolded or folded along the first direction X by using the transmission of the rack 221, the gear 222 and the toothed belt 223, thereby realizing the telescopic function of the telescopic mechanism 200. The fixing frame 230 may have a bending structure, and the fixing frame 230 is connected with a set of telescopic brackets 210 located at the end, so that the flexible screen 900 may be wound on the first transmission mechanism 300 after being bent along the fixing frame 230, so as to facilitate the accommodation of the flexible screen 900 in the accommodating space 101. In this embodiment, the sliding connection between the two sets of telescopic brackets 210 can be achieved by providing a sliding slot and a sliding block for the multiple sets of telescopic brackets 210. In some embodiments, the multiple sets of telescopic supports 210 may also be configured to implement sliding connection between two sets of telescopic supports 210 by providing a sliding rail or a roller, which is not limited in this embodiment.

Referring to fig. 11 to 13 in conjunction with fig. 6 to 7, fig. 11 is a schematic diagram of a connection structure between the first transmission mechanism 300 and the mounting plate 121 in fig. 3, fig. 12 is a schematic diagram of a structure of the first transmission mechanism 300 in fig. 11, and fig. 13 is an exploded schematic diagram of the first transmission mechanism 300 in fig. 11.

The first transmission mechanism 300 may be used to drive the rotation mechanism 400 and the sliding mechanism 500 to move, and the other end of the flexible screen 900 may be wound around the first transmission mechanism 300 to be unfolded or folded under the driving of the first transmission mechanism 300. As shown in fig. 11 to 13, the first transmission mechanism 300 may be disposed in the accommodating space 101 and connected to the mounting plate 121 of the housing 100. The first transmission 300 may include: a first shaft assembly 310 and a first transmission assembly 320. The first shaft assembly 310 may be disposed through two opposite sides of the housing 100, that is, through the mounting plate 121, and may rotate relative to the mounting plate 121. The first transmission assembly 320 may be sleeved on the first shaft assembly 310, and may be driven by the first shaft assembly 310 to move. The first rotating shaft assembly 310 may be connected to the rotating mechanism 400 and the sliding mechanism 500, respectively, to move the rotating mechanism 400 and the sliding mechanism 500. The other end of the flexible screen 900 may be wound around the first transmission component 320, and may be unfolded or folded along the first direction X under the driving of the first transmission component 320. In this embodiment, the first transmission component 320 may move synchronously with the telescopic mechanism 200, and the displacement amount of the end, connected to the telescopic mechanism 200, of the flexible screen 900 on the telescopic mechanism 200 may be the same as the variable amount of the other end, wound around the first transmission component 320, of the flexible screen 900, so that the probability that the flexible screen 900 is pulled by the telescopic mechanism 200 can be reduced, friction generated between the flexible screen 900 and the telescopic mechanism 200 in the unfolding or folding process is reduced, and the service life of the flexible screen 900 is prolonged.

Specifically, the first shaft assembly 310 may include: a first rotation shaft 311 and a second rotation shaft 312. The first rotating shaft 311 and the second rotating shaft 312 may be disposed through the mounting plate 121 on opposite sides of the housing 100, and may rotate relative to the mounting plate 121. Meanwhile, the first rotation shaft 311 and the second rotation shaft 312 may be disposed in parallel to ensure rotation consistency of the first rotation shaft 311 and the second rotation shaft 312. The first transmission assembly 320 may be sleeved on the first shaft 311 and the second shaft 312, and may be driven by the first shaft 311 to move so as to drive the second shaft 312 to rotate relative to the mounting plate 121. In this embodiment, one end of the first shaft 311 penetrating through the mounting plate 121 may be exposed in the accommodating cavity 102 for being connected to the first power mechanism 600, so that the first shaft 311 may rotate relative to the mounting plate 121 under the driving of the first power mechanism 600. One end of the second rotating shaft 312 penetrating through the mounting plate 121 may also be exposed in the accommodating cavity 102, and is used for being connected with the rotating mechanism 400 and the sliding mechanism 500, so that the rotating mechanism 400 and the sliding mechanism 500 may move under the driving of the second rotating shaft 312, thereby implementing the telescopic function of the telescopic mechanism 200. For example, the end of the first shaft 311 exposed in the receiving chamber 102 may be provided with a gear, and the gear may be engaged with the first power mechanism 600 to perform a transmission function. The end of the second rotating shaft 312 exposed in the accommodating cavity 102 may also be provided with a gear, and the gear may be simultaneously meshed with the rotating mechanism 400 and the sliding mechanism 500 to realize a transmission function.

The first transmission assembly 320 may include: a first pulley 321, a second pulley 322, and a first belt 323. Wherein, the first belt wheel 321 can be sleeved on the first rotating shaft 311, the second belt wheel 322 can be sleeved on the second rotating shaft 312, and the first belt 323 can be sleeved on the first belt wheel 321 and the second belt wheel 322. Meanwhile, the first pulley 321 and the second pulley 322 may be provided with corresponding teeth, and the first transmission belt 323 may be engaged with the teeth of the first pulley 321 and the second pulley 322. So set up, when first pivot 311 rotates for mounting panel 121, first band pulley 321 can rotate under the drive of first pivot 311, and first conveyer 323 can be under the drive of first pivot 311 motion, and second band pulley 322 can drive second pivot 312 and rotate for mounting panel 121 under the drive of first conveyer 323 to realize whole transmission process. Accordingly, the flexible screen 900 may be unfolded or folded under the driving of the telescopic mechanism 200 and the first conveyor 323, thereby realizing a larger screen area with a limited size of the main body. In this embodiment, three sets of first transmission assemblies 320 may be disposed on the first and

second shafts

311 and 312 to facilitate winding the flexible screen 900 around the first transmission assemblies 320.

In the above transmission process, since the telescopic mechanism 200 is driven by the sliding mechanism 500 to perform telescopic motion along the first direction X, and the sliding mechanism 500 is driven by the rotation of the second rotating shaft 312, the telescopic motion of the telescopic mechanism 200 and the motion of the first conveying belt 323 can be performed synchronously, so that the flexible screen 900 can be pulled by the telescopic mechanism 200, and meanwhile, the flexible screen 900 can be sent out from the accommodating space 101 by the first conveying belt 323, so that the displacement of the flexible screen 900 on the telescopic mechanism 200 is ensured to be the same as the variation of the flexible screen 900 on the first conveying belt 323, thereby reducing the probability that the flexible screen 900 is pulled by the telescopic mechanism 200, reducing the friction between the telescopic mechanism 200 and the flexible screen 900, and improving the service life of the flexible screen 900. Similarly, when the telescopic mechanism 200 is retracted into the accommodating space 101, the first conveyor belt 323 can also pull the flexible screen 900 toward the accommodating space 101, so that the flexible screen 900 is prevented from being wrinkled on the telescopic mechanism 200, and the flatness of the flexible screen 900 in the folding process is maintained.

Referring to fig. 14 to 17 in conjunction with fig. 6, fig. 14 is a schematic diagram of a connection structure of the rotating mechanism 400, the sliding mechanism 500, the mounting plate 121 and the first transmission mechanism 300 in fig. 3, fig. 15 is a schematic diagram of a connection structure of the rotating mechanism 400, the sliding mechanism 500, the mounting plate 121 and the first transmission mechanism 300 in fig. 14 at another view angle, fig. 16 is a partially enlarged view at D in fig. 14, and fig. 17 is a schematic diagram of a structure of the third rotation shaft 411 and the fourth rotation shaft 421 in fig. 14.

The rotation mechanism 400 may be located on a movement path of the flexible screen 900 for unfolding or folding, and contact with the flexible screen 900, so as to move under the driving of the second rotation shaft 312, so as to further reduce friction between the flexible screen 900 and the telescopic mechanism 200. As shown in fig. 6 and 14 to 15, the rotation mechanism 400 may include: a first rotating assembly 410 and a second rotating assembly 420. The first rotating component 410 may be disposed at a bending area a of the flexible screen 900 on the fixing frame 230, the second rotating component 420 may be disposed at another bending area B of the flexible screen 900 on the fixing frame 230, and both the first rotating component 410 and the second rotating component 420 are in contact with the flexible screen 900. Meanwhile, the first rotating assembly 410 may be connected to one end of the second rotating shaft 312 penetrating the mounting plate 121, that is, the second rotating shaft 312 is exposed at one end of the accommodating cavity 102. The second rotation assembly 420 may be connected with the sliding mechanism 500. So configured, when the second rotating shaft 312 rotates relative to the mounting plate 121, the first rotating assembly 410 can rotate under the driving of the second rotating shaft 312. The sliding mechanism 500 may be driven by the second rotating shaft 312 to drive the second rotating assembly 420 to rotate. Therefore, the first transmission mechanism 300, the sliding mechanism 500, the first rotating assembly 410 and the second rotating assembly 420 can synchronously move, and when the flexible screen 900 is driven to be unfolded or folded, the friction between the flexible screen 900 and the telescopic mechanism 200 can be reduced at the bending area A and the bending area B by the first rotating assembly 410 and the second rotating assembly 420, so that the service life of the flexible screen 900 is prolonged.

As shown in fig. 16 to 17, the first rotating assembly 410 may include: a third rotation shaft 411 and a first gear 412. The third rotating shaft 411 may be disposed through the mounting plates 121 on opposite sides of the housing 100, and is disposed in a bending area a of the flexible screen 900 in the fixing frame 230, and is parallel to the first rotating shaft 311. Meanwhile, the end of the third rotating shaft 411 exposed from the accommodating cavity 102 may be further provided with a gear, so as to be meshed with the first gear 412 to realize transmission. The first gear 412 may be disposed in the accommodating cavity 102 and engaged with an end portion of the third rotating shaft 411 exposed from the accommodating cavity 102. At the same time, the first gear 412 is also meshed with the end of the second rotating shaft 312 exposed from the accommodating cavity 102. So configured, when the second rotating shaft 312 rotates relative to the mounting plate 121, the first gear 412 can rotate relative to the mounting plate 121 under the driving of the second rotating shaft 312, and further drive the third rotating shaft 411 to rotate relative to the mounting plate 121. As shown in fig. 6, since the third rotating shaft 411 may contact the bending area a of the flexible screen 900, the third rotating shaft 411 may move synchronously with the second rotating shaft 312 and the sliding mechanism 500 during the unfolding or folding process of the flexible screen 900, so as to reduce friction between the flexible screen 900 and the telescopic mechanism 200 at the bending area a.

The first gear 412 may be used to maintain the outer circumferential speed of the second rotary shaft 312 equal to the outer circumferential speed of the third rotary shaft 411 in addition to the transmission between the second rotary shaft 312 and the third rotary shaft 411, so that friction between the third rotary shaft 411 and the flexible screen 900 is minimized. For example, the first gear 412 may be a double gear having one large gear and one small gear. The first gear 412 may be disposed on the mounting plate 121 and may rotate relative to the mounting plate 121. Meanwhile, a large gear of the first gear 412 may be engaged with a gear of an end of the second rotation shaft 312, and a small gear of the first gear 412 may be engaged with a gear of an end of the third rotation shaft 411. Therefore, when the second rotating shaft 312 rotates relative to the mounting plate 121, the first gear 412 is used for reducing the transmission speed, so that the outer circle linear speeds of the third rotating shaft 411 and the second rotating shaft 312 can be kept equal, friction between the flexible screen 900 and the third rotating shaft 411 is minimized, friction applied to the flexible screen 900 is further reduced, and the service life of the flexible screen 900 is prolonged.

As shown in fig. 16 to 17, the second rotating assembly 420 may include: a fourth rotation shaft 421 and a second gear 422. The fourth rotating shaft 421 may be disposed through the mounting plates 121 on two opposite sides of the housing 100, and is disposed in the other bending region B of the fixing frame 230 of the flexible screen 900, and is parallel to the first rotating shaft 311. Meanwhile, the end of the fourth rotation shaft 421 exposed to the receiving cavity 102 may be provided with a gear so as to be engaged with the second gear 422 to achieve transmission. The second gear 422 may be disposed in the accommodating chamber 102 and engaged with an end portion of the fourth rotation shaft 421 exposed to the accommodating chamber 102. At the same time, the second gear 422 is also engaged with the sliding mechanism 500. So configured, when the second rotating shaft 312 drives the sliding mechanism 500 to move, the sliding mechanism 500 may drive the fourth rotating shaft 421 to rotate relative to the mounting plate 121 through the second gear 422. As shown in fig. 6, since the fourth rotating shaft 421 may contact the bending region B of the flexible screen 900, the fourth rotating shaft 421 may move synchronously with the second rotating shaft 312 and the sliding mechanism 500 during the process of expanding or collapsing the flexible screen 900, so as to reduce friction between the bending region B and the telescopic mechanism 200 of the flexible screen 900.

Accordingly, the second gear 422 may be used to realize transmission between the sliding mechanism 500 and the fourth rotating shaft 421, and may also cooperate with the sliding mechanism 500 to maintain the outer circular linear speed of the second rotating shaft 312 equal to the outer circular linear speed of the fourth rotating shaft 421, so that friction between the fourth rotating shaft 421 and the flexible screen 900 is minimized, thereby further reducing friction suffered by the flexible screen 900 and improving the service life of the flexible screen 900. In this embodiment, the first gear 412 and the second gear 422 may be disposed in the accommodating chamber 102 of the same sidewall 120, that is, on the same side of the mounting plate 121.

In the above transmission process, since the third rotation shaft 411 and the fourth rotation shaft 421 are driven by the rotation of the second rotation shaft 312, the third rotation shaft 411 and the fourth rotation shaft 421 can move synchronously with the second rotation shaft 312, so as to reduce friction between the flexible screen 900 and the telescopic mechanism 200 in the bending region a and the bending region B. And the first gear 412 is arranged between the second rotating shaft 312 and the third rotating shaft 411 to perform transmission speed reduction, and the sliding mechanism 500 and the second gear 422 are arranged between the second rotating shaft 312 and the fourth rotating shaft 421 to perform transmission speed reduction, so that the outer circular linear speeds of the third rotating shaft 411 and the fourth rotating shaft 421 can be consistent with the outer circular linear speed of the second rotating shaft 312, friction between the flexible screen 900 and the third rotating shaft 411 and the fourth rotating shaft 421 is reduced, and the service life of the flexible screen 900 is further prolonged.

As shown in fig. 14 to 15, the sliding mechanism 500 may be disposed in the accommodating cavity 102, and the sliding mechanism 500 may be used to drive the telescopic mechanism 200 to stretch along the first direction X, and drive the fourth rotating shaft 421 to rotate relative to the mounting plate 121, so as to further realize the unfolding or folding of the flexible screen 900, and reduce the friction between the flexible screen 900 and the telescopic mechanism 200. The sliding mechanism 500 may include: a third gear 510 and a second transmission assembly 520. Wherein, the third gear 510 and the second transmission assembly 520 may be disposed on the mounting plate 121 and located in the accommodating cavity 102. The third gear 510 may be engaged with an end portion of the second shaft 312 exposed to the accommodating cavity 102, and the second transmission assembly 520, respectively, to perform a transmission function. The second transmission assembly 520 may be connected to the telescopic mechanism 200, and the second transmission assembly 520 may slide along the first direction X relative to the mounting plate 121 under the driving of the third gear 510, so as to drive the telescopic mechanism 200 to extend or retract into the accommodating space 101 along the first direction X. Meanwhile, the second transmission assembly 520 may further mesh with the second gear 422, so as to drive the second gear 422 to rotate during the movement process, and further drive the fourth rotating shaft 421 to rotate relative to the mounting plate 121.

Specifically, the third gear 510 may be disposed at one side of the mounting plate 121 and located within the receiving chamber 102. The third gear 510 may be engaged with the second shaft 312 and the second transmission assembly 520, respectively, to effect transmission between the second shaft 312 and the second transmission assembly 520. For example, the third gear 510 may be a double gear having a large gear and a small gear. Wherein, the large gear on the third gear 510 can be meshed with the end portion of the second rotating shaft 312 exposed out of the accommodating cavity 102, and the small gear on the third gear 510 can be meshed with the second transmission assembly 520. Therefore, when the second rotating shaft 312 rotates relative to the mounting plate 121, the third gear 510 can drive the second transmission assembly 520 to slide in the first direction X, and further drive the telescopic mechanism 200 to extend or retract into the accommodating space 101.

The second transmission assembly 520 may include: a third pulley 521, a fourth pulley 522, a second belt 523, and a slider 524. The third pulley 521 may be disposed on one side of the mounting plate 121 and located in the accommodating cavity 102 to be engaged with the third gear 510. The fourth pulley 522 may be disposed on the same side of the mounting plate 121 as the third pulley 521 and spaced apart from the third pulley 521 in the first direction X to reserve a sliding space of the slider 524. The second belt 523 may be looped over the third pulley 521 and the fourth pulley 522. The third pulley 521 and the fourth pulley 522 may be provided with corresponding teeth, and the second transmission belt 523 may be engaged with the teeth of the third pulley 521 and the fourth pulley 522. The slider 524 may be disposed on the second conveyor belt 523, and the slider 524 may be connected with the connection arm 211 on the telescopic bracket 210. So configured, when the third gear 510 rotates under the driving of the second rotating shaft 312, the third pulley 521 can rotate under the driving of the third gear 510, and further drive the second conveyor belt 523 to move. The fourth pulley 522 may rotate under the drive of the second belt 523. Accordingly, the sliding member 524 can slide in the first direction X relative to the mounting plate 121 along with the movement of the second conveyor belt 523, so as to drive the telescopic mechanism 200 to extend and retract in the first direction X, thereby realizing the whole transmission process of the sliding mechanism 500. In this embodiment, the sliding mechanisms 500 may be disposed on two opposite sides of the housing 100, that is, the sliding mechanisms 500 are disposed in the accommodating chambers 102 of the two side walls 120, so that the sliding mechanisms 500 may drive the telescopic mechanisms 200 from two sides to stretch and retract, so as to maintain the balance and consistency of the stretching of the telescopic mechanisms 200, and avoid the jamming or tilting caused by stretching of the telescopic mechanisms 200 driven by one side.

Further, the third pulley 521 can be engaged with the second gear 422 to drive the second gear 422 to rotate, and further drive the fourth shaft 421 to rotate relative to the mounting plate 121, in addition to the transmission. Therefore, when the second rotating shaft 312 rotates relative to the mounting plate 121, the third gear 510, the third pulley 521 and the second gear 422 can perform transmission deceleration, so as to keep the outer circular line speeds of the fourth rotating shaft 421 and the second rotating shaft 312 equal, and reduce friction between the flexible screen 900 and the telescopic mechanism 200 in the bending region B.

In the present embodiment, the second rotation shaft 312 and the third pulley 521 are engaged with each other by the third gear 510, and the slider 524 is connected to the telescopic mechanism 200. So that the first power mechanism 600 can drive the first conveyor 323 and the telescopic bracket 210 at the same time. Meanwhile, after the meshing transmission among the second rotating shaft 312, the third gear 510 and the third belt wheel 521 is decelerated, the flexible screen 900 is wound on one end of the first conveying belt 323, the winding variable quantity on the first conveying belt 323 can be equal to the displacement quantity of one end, connected with the flexible screen 900 and the telescopic bracket 210, of the flexible screen 900, so that the first conveying belt 323 and the telescopic bracket 210 can synchronously move, friction between the flexible screen 900 and the telescopic mechanism 200 in the unfolding or folding process is reduced, and the service life of the flexible screen 900 is prolonged.

Further, by the engagement of the first gear 412 with the second rotating shaft 312, the second gear 422 is engaged with the third pulley 521, so that the third rotating shaft 411 and the fourth rotating shaft 421 can rotate relative to the mounting plate 121 under the driving of the second rotating shaft 312 and the third pulley 521, thereby reducing friction of the flexible screen 900 in the bending region a and the bending region B. Meanwhile, through the transmission speed reduction between the first gear 412 and the third gear 510, the third belt wheel 521 and the second gear 422, the outer circular linear speed of the third rotating shaft 411 and the fourth rotating shaft 421 can be equal to the outer circular linear speed of the second rotating shaft 312, so that the friction between the flexible screen 900 and the third rotating shaft 411 and the fourth rotating shaft 421 is minimized, the friction suffered by the flexible screen 900 is further reduced, and the service life of the flexible screen 900 is prolonged.

Referring to fig. 18, fig. 18 is a schematic diagram illustrating a connection structure of the mounting plate 121, the first transmission mechanism 300, the rotation mechanism 400, the sliding mechanism 500, and the first power mechanism 600 in fig. 3.

The first power mechanism 600 may be disposed in the accommodating space 101, and the first power mechanism 600 may be used to drive the first transmission mechanism 300 to move, and further drive the telescopic mechanism 200 to move through the sliding mechanism 500, so as to realize the unfolding or folding of the flexible screen 900. As shown in fig. 17, the first power mechanism 600 may include: a power member 610 and a gear assembly 620. The power member 610 may be disposed in the accommodating space 101 and electrically connected to the motherboard of the electronic device 10. The transmission shaft of the power member 610 may be disposed through the mounting plate 121, and one end of the transmission shaft may be exposed in the accommodating cavity 102 and disposed parallel to the first rotation shaft 311. Meanwhile, the end of the transmission shaft exposed to the accommodating cavity 102 may be further provided with a gear so as to facilitate the engagement transmission of the transmission shaft with the gear assembly 620. The gear assembly 620 may be disposed at one side of the mounting plate 121 and engaged with a driving shaft of the power member 610. The gear assembly 620 is also engaged with the end of the first shaft 311 exposed to the receiving cavity 102. So configured, when the power member 610 works, the transmission shaft thereof can drive the gear assembly 620 to rotate, and further drive the first rotating shaft 311 to rotate, thereby realizing the movement of the first transmission mechanism 300. In this embodiment, the power unit 610 may be a stepper motor, which may rotate under the control of the motherboard of the electronic device 10 to drive the first transmission mechanism 300 to move. The gear assembly 620 may include three intermeshing double gears for ensuring precise transmission of the power member 610 while reducing rotational speed, increasing torque, and reducing the moment of inertia ratio of the load/motor. In some embodiments, the power unit 610 may be a servo motor, and the gear assembly 620 may have a gear number not limited to three, and may be specifically set according to actual requirements.

Referring to fig. 19 to 21 in conjunction with fig. 6, fig. 19 is a schematic diagram of a connection structure of the mounting plate 121, the first transmission mechanism 300, the rotation mechanism 400, the sliding mechanism 500, the first power mechanism 600, the second power mechanism 700 and the second transmission mechanism 800 in fig. 3, fig. 20 is a partially enlarged view of E in fig. 19, and fig. 21 is a schematic diagram of a connection structure of the fifth rotation shaft 811 and the sixth rotation shaft 812 in fig. 18.

The second power mechanism 700 and the second transmission mechanism 800 may be disposed in the accommodating space 101, and both may be used to achieve the expansion or contraction of the protective film 1000, and maintain the consistency of the expansion or contraction of the flexible screen 900 and the protective film 1000. As shown in fig. 6 and 19, the second power mechanism 700 may be the same or similar in structure as the first power mechanism 600, except that the second power mechanism 700 is provided with only power components, unlike the first power mechanism 600. That is, the second power mechanism 700 may be the same stepper motor as the power member 610, and the transmission shaft of the second power mechanism 700 may be penetrated through the mounting plate 121 and exposed in the receiving cavity 102. Meanwhile, the end of the transmission shaft exposed from the accommodating cavity 102 may also be provided with a gear, so that the second power mechanism 700 and the second transmission mechanism 800 can perform meshed transmission.

The second transmission mechanism 800 may be driven by the second power mechanism 700 to drive the protective film 1000 to be unfolded or folded along the first direction X. As shown in fig. 6 and 20 to 21, the second transmission 800 may include: a second shaft assembly 810 and a fourth gear 820. The second shaft assembly 810 may be disposed through the mounting plates 121 on two opposite sides and parallel to the first shaft 311. One end of the protective film 1000 may be connected to the telescopic mechanism 200, and the other end may be wound around the second rotation shaft assembly 810. The fourth gear 820 is disposed in the accommodating chamber 102, and the fourth gear 820 may be engaged with a transmission shaft of the second power mechanism 700. Meanwhile, the fourth gear 820 may also be engaged with the second shaft assembly 810. When the second power mechanism 700 starts to rotate, the fourth gear 820 can drive the second rotating shaft assembly 810 to rotate relative to the mounting plate 121, so that the protective film 1000 wound on the second rotating shaft assembly 810 can be unfolded or folded under the driving of the second rotating shaft assembly 810.

Specifically, the second shaft assembly 810 may include: a fifth rotation shaft 811 and a sixth rotation shaft 812. The fifth rotating shaft 811 and the sixth rotating shaft 812 may be disposed through the mounting plates 121 on two opposite sides, and may be disposed parallel to the first rotating shaft 311. Meanwhile, one end of the fifth rotating shaft 811 penetrating the mounting plate 121 may be exposed in the accommodating cavity 102, and an end thereof may be further provided with a gear. One end of the sixth rotating shaft 812 penetrating through the mounting plate 121 may be exposed in the accommodating cavity 102, and the end thereof may be provided with a gear. Thus, the ends of the fifth and sixth

rotating shafts

811 and 812 located in the accommodating chamber 102 may be engaged to achieve transmission between the fifth and sixth

rotating shafts

811 and 812. As shown in fig. 20, the end portion of the sixth rotating shaft 812 located in the accommodating cavity 102 may further be meshed with the fourth gear 820, so that when the fourth gear 820 is driven to rotate by the second power mechanism 700, the sixth rotating shaft 812 may drive the fifth rotating shaft 811 to rotate. As shown in fig. 6, the other end of the protective film 1000 may be wound around the fifth rotation shaft 811, and the sixth rotation shaft 812 may be positioned on a movement path of the protective film 1000 to be unfolded or folded, for providing a guiding function for the movement of the protective film 1000. The rotation directions of the fifth rotation shaft 811 and the sixth rotation shaft 812 may be opposite to ensure the movement consistency of the protective film 1000 on the fifth rotation shaft 811 and the sixth rotation shaft 812.

Further, the fourth gear 820 may be located in the receiving cavity 102 of the other sidewall 120, i.e., the fourth gear 820 and the first gear 412 may be located in the two receiving cavities 102, respectively, to facilitate assembly. Meanwhile, in order to be matched with the installation positions of the fifth rotating shaft 811 and the sixth rotating shaft 812, the fourth gear 820 may be sleeved at one end of the second rotating shaft 312 exposed in the accommodating cavity 102, and may rotate relative to the second rotating shaft 312 under the driving of the second power mechanism 700. That is, the rotation of the fourth gear 820 is independent of the rotation of the second rotary shaft 312. Therefore, when the second power mechanism 700 drives the fourth gear 820 to rotate relative to the second rotating shaft 312, the normal motion of the first transmission mechanism 300 is not affected, and thus independent driving of the flexible screen 900 and the protective film 1000 is realized. Of course, in order to ensure that the flexible screen 900 and the protective film 1000 can be unfolded or folded simultaneously, the second power mechanism 700 and the first power mechanism 600 can be speed-matched under the control of the main board, so as to ensure the motion consistency of the flexible screen 900 and the protective film 1000.

The electronic device 10 provided in this embodiment drives the first transmission mechanism 300 to move through the first power mechanism 600, and the first transmission mechanism 300 drives the sliding mechanism 500 to slide in the extending direction of the sliding mechanism 200, so that the sliding mechanism 200 connected with the sliding mechanism 500 can extend or retract into the accommodating space 101 under the driving of the sliding mechanism 500. By connecting one end of the flexible screen 900 with the telescopic mechanism 200 and winding the other end on the first transmission mechanism 300, the flexible screen 900 can be unfolded or folded when the telescopic mechanism 200 stretches and contracts, so that larger screen display can be realized in a limited body size. Meanwhile, since the movement of the first transmission mechanism 300 and the expansion of the expansion mechanism 200 are driven by the first power mechanism, the expansion mechanism 200 and the first transmission mechanism 300 can synchronously move in the process of expanding or collapsing the flexible screen 900, so that the probability of the expansion mechanism 200 dragging the flexible screen 900 can be reduced, the friction between the flexible screen 900 and the expansion mechanism 200 is reduced, and the service life of the flexible screen 900 is prolonged.

The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent process transformations made by using the descriptions and the drawings of the present application, or direct or indirect application to other related technical fields, are included in the patent protection scope of the present application.
