Description

Technical Field

[0001] The present application relates to the technical field of retractable screen products, and in particular to a retractable screen structure and electronic equipment. Background Art

[0002] As people's requirements for products increase, when handling different tasks such as watching videos and making phone calls, it is necessary to increase or reduce the display area to improve the product experience. Currently, there are mainly two types of screen expansion structures: folding screen structure and retractable screen structure.

[0003] The existing retractable screen structure mainly adopts a grid-type staggered spacing support. In this solution, there is a gap in the supporting part when the screen is unfolded. Since the screen is flexible, this gap will cause the unfolded screen to be not flat enough and unable to withstand greater pressure. Summary of the invention

[0050] This application provides a telescopic screen structure. The following will describe the telescopic screen structure and the electronic device of this application in detail with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0051] See Figures 1 to 7 As shown, the telescopic screen structure provided by this application can be used in an electronic device. The electronic device can be, for example, a mobile phone, a tablet computer, or other electric telescopic devices that can apply a flexible display screen. The telescopic screen structure includes a housing 10, a support assembly 30, and a flexible display screen 40. The housing 10 includes a bottom shell and side shells surrounding the bottom shell. The housing 10 has an opening. The support assembly 30 is disposed inside the housing 10, and the flexible display screen 40 is disposed on the support assembly 30 and covers the opening. The support assembly 30 serves to support the flexible display screen 40.

[0052] Among them, the housing 10 includes a first housing 11 and a second housing 12 movably connected to the first housing 11. The first housing 11 and the second housing 12 respectively include a bottom shell and part of the side shells. The first housing 11 and the second housing 12 enclose a receiving structure with an opening, as Figure 2 and Figure 3 shown. The opening is located at the top of the housing 10. It can be understood that the second housing 12 is slidably disposed on the first housing 11 in a first direction (as Figure 2 shown as horizontal), which can play a role in protecting the internal structure, preventing dust and dirt. The slidable arrangement can make the expansion of the telescopic screen structure smoother. The flexible display screen 40 can adopt a common OLED soft screen currently. The first end of the flexible display screen 40 ( Figure 3 shown as the right end in the figure) is connected to the second housing 12, and the connection method can be fixed by dispensing glue. The second end of the flexible display screen 40 is bent along the inner wall of the first housing 11 into the first housing 11. When the second housing 12 slides to the limit position in the first direction (as Figure 2 shown as horizontal), the second end of the flexible display screen 40 is always located inside the housing 10, improving the overall ornamental property and dust and dirt prevention.

[0053] The support assembly includes a first support plate and a movable support plate. The first support plate is connected to the first housing 11. The movable support plate is movably connected to the first support plate and is in transmission connection with the second housing. When the second housing 12 moves relative to the first housing 11 along the first direction (such as Figure 2 shown as horizontal), it will drive the movable support plate to move relative to the first support plate along the first direction, and drive the first end of the flexible display screen to move relative to the first housing 11 along the first direction (such as Figure 2 shown as horizontal), so as to switch the flexible display screen between the retracted state and the unfolded state, realizing the telescopic effect of the flexible display screen. Both the first support plate and the movable support plate belong to plate-like structures. When the second housing 12 and the movable support plate move to the limit position, the support assembly is fully unfolded, realizing a full-plane non-gap support, which well solves the problems of uneven screen and inability to withstand large pressing caused by the current staggered interval support.

[0054] When the telescopic screen structure is in the retracted state (which can be understood as the retracted state), the movable support plate is located on the side of the first support plate away from the opening, and the flexible display screen covers the surface of the first support plate close to the opening. The size of the actual display area of the flexible display screen along the first direction is the same as the size of the first support plate along the first direction. When the telescopic screen structure is in the unfolded state (which can be understood as the unfolded state), the movable support plate moves along the first direction until the surface of the movable support plate close to the opening is flush with the surface of the first support plate close to the opening, and the flexible display screen moves to cover the surfaces of the first support plate and the movable support plate close to the opening. The size of the actual display area of the flexible display screen along the first direction is the same as the sum of the sizes of the first support plate and the movable support plate along the first direction, increasing the display area of the flexible display screen, thereby realizing the telescopic effect of the flexible display screen.

[0055] See Figure 2 and Figure 3 shown. In an optional embodiment, in order to further increase the screen stretching area of the flexible display screen, the support assembly 30 further includes a second support plate 32. The surface of the second support plate 32 close to the opening is flush with the surface of the first support plate 31 close to the opening. The second support plate 32 is connected to the second housing 12 and is movably connected to the movable support plate 33. The second support plate 32 moves along the first direction (such as Figure 2 shown as horizontal), driving the second housing 12, the movable support plate 33, and the first end of the flexible display screen 40 to move along the first direction (such as Figure 2It is shown as a lateral movement, thereby realizing the telescopic effect of the flexible display screen. Setting the second support plate 32 can make the deployable length of the telescopic screen structure longer, and it can be applied to more situations. In this embodiment, the first support plate 31 and the second support plate 32 are symmetrically arranged on both sides of the movable support plate 33, making the movement of the second support plate 32 smoother.

[0056] See Figure 2 and Figure 6 As shown, when the telescopic screen structure is in the retracted state, the second support plate 32 abuts against the first support plate 31, and the movable support plate 33 is located on the side of the first support plate 31 and the second support plate 32 away from the opening, that is, the movable support plate 33 is hidden below the first support plate 31 and the second support plate 32, and the first housing 11 and the second housing 12 are joined together. The flexible display screen 40 covers the surfaces of the first support plate 31 and the second support plate 32 close to the opening. The size of the actual display area of the flexible display screen in the first direction (such as Figure 2 shown as lateral) is the same as the sum of the sizes of the first support plate 31 and the second support plate 32 in the first direction; as Figure 3 and Figure 7 shown, when the telescopic screen structure is in the deployed state, the second support plate 32 moves in the first direction (such as Figure 2 shown as lateral) to form a gap with the first support plate 31, and the movable support plate 33 moves into the gap and abuts against the first support plate 31 and the second support plate 32. The surface of the movable support plate 33 close to the opening is flush with the surfaces of the first support plate 31 and the second support plate 32 close to the opening, that is, the movable support plate 33 is exposed from below the first support plate 31 and the second support plate 32, and the second housing 12 is deployed relative to the first housing 12. The flexible display screen 40 covers the surfaces of the first support plate 31, the second support plate 32, and the movable support plate 33 close to the opening. The size of the actual display area of the flexible display screen in the first direction (such as Figure 2 shown as lateral) is the same as the sum of the sizes of the first support plate 31, the second support plate 32, and the movable support plate 33 in the first direction (such as Figure 2 shown as lateral), increasing the display area of the flexible display screen, thereby realizing the telescopic effect of the flexible display screen.

[0057] See Figure 1 and Figures 4 to 5As shown, in an optional embodiment, the telescopic screen structure further includes a transmission assembly. The transmission assembly includes a traction belt 221, a first roller 222, and a second roller 223. Both the first roller 222 and the second roller 223 are fixedly connected to the first housing 11. The first roller 222 is located on one side close to the first support plate 31, and the second roller 223 is located on one side close to the second support plate 32. The first roller 222 and the second roller 223 act as fixed pulleys, which can ensure that the movement distances of the flexible display screen 40, the support assembly 30, and the second housing 12 are equal, avoiding complex mechanical transmissions. The first end ( Figure 5 shown as the upper end in the figure) of the traction belt 221 bypasses the second roller 223 and is connected to the end of the second support plate 32 close to the first support plate 31, and can be fixedly connected by means such as bonding or screws. The second end of the flexible display screen 40 bypasses the first roller 222 and is connected to the second end ( Figure 5 shown as the lower end in the figure) of the traction belt 221. Since the screen is directly pulled, the reliability and linkage are high, solving a series of problems such as unstable telescoping of the telescopic screen and easy jamming. In this embodiment, the flexible display screen 40 uses an OLED flexible screen. A base material is provided at the bottom layer of the OLED flexible screen package. The flexible display screen 40 can be bonded to the traction belt 221 through the base material. In this embodiment, the first roller 222 can adopt a roller shaft and is arranged at the left end of the first housing 11 along the Figure 1 height direction of the flexible display screen 40 shown in the figure. The second roller 223 can adopt a fixed pulley, and the number can be two, and is arranged on the upper and lower sides of the right end of the first housing 11 along the Figure 1 height direction of the flexible display screen shown in the figure. The number of the traction belts 221 can be two. One traction belt 221 bypasses one of the second rollers 223 and then winds around the first roller 222, and the other traction belt 221 bypasses the other second roller 223 and then winds around the first roller 222. That is, as Figure 1 shown, both the upper and lower sides of the flexible display screen 40 along the height direction are connected to the second support plate 32 through a traction belt 221, which can make the forces on both sides balanced when the flexible display screen 40 moves.

[0058] When the telescopic screen structure switches from the unfolded state to the retracted state, the first end of the flexible display screen 40 moves in the first direction (such as Figure 4 shown as horizontal in the figure) towards the direction of the first support plate 31, and the second end of the flexible display screen 40 moves in the first direction (such as Figure 4As shown, it moves in the lateral direction) towards the direction of the second support plate 32 and gradually retracts into the housing 10. During the movement, the flexible display screen 40 always covers the surface of the support assembly 30 close to the opening; when the telescopic screen structure switches from the retracted state to the deployed state, the first end of the flexible display screen 40 moves in the first direction (such as Figure 4 As shown, it moves in the lateral direction) towards the direction of the second support plate 32, and the second end of the flexible display screen 40 moves in the first direction (such as Figure 4 As shown, it moves in the lateral direction) towards the direction of the first support plate 31 and gradually unfolds and covers the support assembly 30. During the movement, the flexible display screen 40 always covers the surface of the support assembly 30 close to the opening.

[0059] Refer to Figures 1 to 8 As shown, in an alternative embodiment, the telescopic screen structure further includes a driving assembly 20 for driving the second support plate 32 to move in the first direction (such as Figure 2 As shown, it moves in the lateral direction). The driving assembly 20 is disposed within the housing 10, that is, the driving assembly is used to drive the deployment and retraction of the telescopic screen structure. The driving assembly 20 includes a driving member 21 for providing a power source and a transmission member 22 connected to the driving member 21. In this embodiment, the support assembly 30 includes a first support plate 31, a second support plate 32, and a movable support plate 33. The transmission member 22 is connected to the second support plate 32. The driving member 21 drives the transmission member 22 to rotate, and the transmission member 22 converts the rotational force into a linear driving force to drive the second support plate 32 to move in the first direction (such as Figure 2 As shown, it moves in the lateral direction). In other embodiments, when the support assembly only includes a first support plate and a movable support plate, the movable support plate is connected to the second housing. The driving member drives the transmission member to rotate, and the transmission member converts the transmitted force into a linear driving force to drive the movable support plate to move in the first direction (such as Figure 2 As shown, it moves in the lateral direction), which can achieve the same effect of telescoping the screen.

[0060] Since a power source is easier to obtain than a gas source inside an electronic device, and there is no need for complex pipeline design, and problems such as leakage and poor sealing will not occur. In this embodiment, the driving member 21 includes a motor. The motor is disposed within the first housing 11 and fixed to the side wall 121 of the first housing 11. The volume of the motor is small, which can save the stacking space inside the electronic device. The transmission member 22 includes a lead screw connected to the motor. The lead screw is along the first direction (such as Figure 2As shown, it is arranged horizontally). A nut engaging with the lead screw is provided on the second support plate 32, and the nut can be fixed to the second support plate 32. The motor drives the lead screw to rotate, causing the second support plate 32 fixed to the nut to move linearly along the first direction (such as Figure 2 shown as horizontal). The lead screw structure provides stable propulsion, and the vibration generated when the telescopic screen structure is deployed and retracted is relatively small.

[0061] In this embodiment, the number of lead screws is two. One lead screw is connected to one of the motors and engages with the nut fixed to the second support plate 32, and the other lead screw is connected to the other motor and engages with the other nut fixed to the second support plate 32. That is, as Figure 8 shown, both the upper and lower sides of the second support plate 32 in the height direction are connected to the two lead screws through nuts, which can make the forces on both sides of the second support plate 32 more uniform when it moves.

[0062] In other embodiments, the transmission member 22 may also include a gear connected to the motor. The motor can provide the force for the gear to rotate. The second support plate is provided with a rack engaging with the gear, and through the cooperation, the rack can be arranged along the first direction (such as Figure 2 shown as horizontal). The gear-rack structure has a large bearing capacity and stable operation, which can ensure the stability when the telescopic screen structure is deployed and retracted.

[0063] Referring to Figures 9 to 12 shown, in an optional embodiment, the movable support plate 33 includes a bottom plate 332, a first side plate 331, and a second side plate 333. The first side plate 331 and the second side plate 333 are respectively connected to both sides of the bottom plate 332.

[0064] In an optional embodiment, a first slide rail 311 arranged along the first direction is provided on the side of the first support plate 31 away from the opening. The first slide rail 311 includes a first sub-slide rail 3111 abutting against the side of the first support plate 31 away from the opening and a second sub-slide rail 3112 communicating with the first sub-slide rail 3111. The second sub-slide rail 3112 is flush with the surface of the first support plate 31 close to the opening. In this embodiment, the length of the first sub-slide rail 3111 is equal to the length of the contact part between the first support plate 31 and the movable support plate 33 in the retracted state. The first sub-slide rail 3111 and the second sub-slide rail 3112 are along a direction perpendicular to the first direction (such as Figure 9The distance (shown as horizontal) is equal to the height of the first side plate 331 of the movable support plate 33. On the side of the second support plate 32 away from the opening, there is a second slide rail 321 arranged along the first direction. The second slide rail 321 includes a third sub-slide rail 3211 abutting against the side of the second support plate 32 away from the opening and a fourth sub-slide rail 3212 communicating with the third sub-slide rail 3211. The fourth sub-slide rail 3212 is flush with the surface of the second support plate 32 close to the opening. In this embodiment, the length of the second sub-slide rail 3112 is equal to the length of the contact part between the second support plate 32 and the movable support plate 33 in the retracted state, and the third sub-slide rail 3211 and the fourth sub-slide rail 3212 are along a direction perpendicular to the first direction (such as Figure 9 The distance (shown as horizontal) is equal to the height of the second side plate 333 of the movable support plate 33. The above structural arrangement can limit the positional changes of the first support plate 31 and the second support plate 32 relative to the movable support plate 33, ensuring the smoothness during the unfolding and retracting processes of the telescopic screen structure.

[0065] The movable support plate 33 is provided with a first sliding member 334 slidably disposed on the first slide rail 311 and a second sliding member 335 slidably disposed on the second slide rail 321. The first sliding member 334 is disposed on the first side plate 331, and the second sliding member 335 is disposed on the second side plate 333. The first sliding member 334 cooperates with the first slide rail 311, such that the first support plate 31 is movably disposed on the movable support plate 33. The second sliding member 335 cooperates with the second slide rail 321, such that the movable support plate 33 is movably disposed on the second support plate 32. When the telescopic screen structure is in the retracted state, the first sliding member 334 is located within the first sub-slide rail 3111, and the second sliding member 335 is located within the third sub-slide rail 3211. When the telescopic screen structure is in the deployed state, the first sliding member 334 slides to be located within the second sub-slide rail 3112, and the second sliding member 335 slides to be located within the fourth sub-slide rail 3212. In this embodiment, the first sliding member 334 is disposed at one end of the movable support plate 33 close to the first support plate 31, and the second sliding member 335 is disposed at one end of the movable support plate 33 close to the second support plate 32, thereby reducing the lengths of the first slide rail 311 and the second slide rail 321 and enhancing the stability of the first support plate 31 and the second support plate 32. Optionally, the first sub-slide rail 3111, the second sub-slide rail 3112, the third sub-slide rail 3211, and the fourth sub-slide rail 3212 can all adopt a chute structure. The second sub-slide rail 3112 penetrates through the middle position of the first support plate 31, and the fourth sub-slide rail 3212 penetrates through the middle position of the second support plate. When the telescopic screen structure is in the deployed state, the first side plate 331 abuts against the right half of the first support plate 31, and the fourth sub-slide rail 3212 abuts against the left half of the second support plate 32, improving the structural strength of the support assembly.

[0066] In an alternative embodiment, the first sliding member 334 and the second sliding member 335 can be made of a metal material to improve the strength of the first sliding member 334 and the second sliding member 335. Flexible materials can also be provided on both side walls 121 of the first slide rail 311 and the second slide rail 321 along the first direction (such as Figure 9 shown as horizontal) to prevent the shear stress generated by the impact during the deployment and retraction of the telescopic screen structure from reducing the durability of the first sliding member 334 and the second sliding member 335.

[0067] Such as Figure 2 、 Figure 9 and Figure 11As shown, when the telescopic screen structure is in the retracted state, the first side plate 331 abuts against the portion of the first support plate 31 where the first sub-slide rail 3111 is provided, the second side plate 333 abuts against the portion of the second support plate 32 where the third sub-slide rail 3211 is provided, and the bottom plate 332 abuts against the sides of the first support plate 31 and the second support plate 32 away from the opening; as Figure 3 , Figure 10 and Figure 12 As shown, when the telescopic screen structure is in the deployed state, the first side plate 331 abuts against the portion of the first support plate 31 where the first sub-slide rail 3111 is not provided, the second side plate 333 abuts against the portion of the second support plate 32 where the third sub-slide rail 3211 is not provided, the bottom plate 332 is located within the interval and abuts against the first support plate 31 and the second support plate 32, and the surface of the bottom plate 332 close to the opening is flush with the surfaces of the first support plate 31 and the second support plate 32 close to the opening. The flexible display screen 40 covers the first support plate 31, the second support plate 32, and the surface of the bottom plate 332 close to the opening. It should be noted that the thickness of the portion of the first support plate 31 where the first sub-slide rail 3111 is provided is slightly greater than the thickness of the portion where the first sub-slide rail 3111 is not provided, and the thickness of the portion of the second support plate 32 where the third sub-slide rail 3211 is provided is slightly greater than the thickness of the portion where the third sub-slide rail 3211 is not provided.

[0068] In an optional embodiment, the thickness of the bottom plate 332 in the second direction (as shown in Figure 9 as longitudinal) is greater than the thickness of the first side plate 331 in the second direction (as shown in Figure 9 as longitudinal). The thickness difference between the bottom plate 332 and the first side plate 331 in the second direction (as shown in Figure 9 as longitudinal) is the same as the thickness of the first support plate 31 in the second direction (as shown in Figure 9 as longitudinal), which can ensure that when the telescopic screen structure is in the deployed state, the side of the first support plate 31 close to the opening and the side of the bottom plate 332 of the movable support plate 33 close to the opening are in the same plane.

[0069] The thickness of the bottom plate 332 in the second direction (as shown in Figure 9 as longitudinal) is greater than the thickness of the second side plate 333 in the second direction (as shown in Figure 9 as longitudinal). The thickness difference between the bottom plate 332 and the second side plate 333 in the second direction (as shown in Figure 9 as longitudinal) is the same as the thickness of the second support plate 32 in the second direction (as shown in Figure 9The thickness in the longitudinal direction (as shown) is the same, where the second direction is perpendicular to the first direction (such as Figure 9 shown as transverse), which can ensure that when the telescopic screen structure is in the unfolded state, the side of the second support plate 32 close to the opening and the side of the bottom plate 332 of the movable support plate 33 close to the opening are on the same plane.

[0070] In an alternative embodiment, a first inclined surface 312 is provided on the side of the first support plate 31 close to the second support plate 32, and an inclined surface structure 3321 adapted to the first inclined surface 312 is provided on the side wall 121 of the bottom plate 332 on the side of the first side plate 331. This can ensure that during the transition between the retracted state and the unfolded state of the telescopic screen structure, since the first support plate 31 is fixed, when the second support plate 32 drives the first sliding member 334 of the movable support plate 33 to slide in the first sliding rail 311 of the first support plate 31, the lifting of the movable support plate 33 is smoother. The first sliding rail 311 includes a first transition portion 3113 connected between the first sub-sliding rail 3111 and the second sub-sliding rail 3112. The first transition portion 3113 is adapted to the first inclined surface 312, and the inner wall of the first transition portion 3113 is smooth to facilitate the passage of the first sliding member 334.

[0071] A second inclined surface 322 is provided on the side of the second support plate 32 close to the first support plate 31, and an inclined surface structure 3321 adapted to the second inclined surface 322 is provided on the side wall 121 of the bottom plate 332 on the side of the second side plate 333. This can ensure that during the transition between the retracted state and the unfolded state of the telescopic screen structure, since the second support plate 32 moves, when driving the second sliding member 335 of the movable support plate 33 to slide in the second sliding rail 321 of the second support plate 32, the lifting of the movable support plate 33 is smoother. The second sliding rail 321 includes a second transition portion 3213 connected between the third sub-sliding rail 3211 and the fourth sub-sliding rail 3212. The second transition portion 3213 is adapted to the second inclined surface 322, and the inner wall of the second transition portion 3213 is smooth to facilitate the passage of the second sliding member 335.

[0072] In an alternative embodiment, the first housing 11 includes a guide rail provided along the first direction (such as Figure 9 shown as transverse), and the second housing 12 is slidably disposed on the guide rail, which can make the unfolding and retracting of the telescopic screen structure smoother.

[0073] Refer to again Figure 1 、 Figure 6 and Figure 7As shown, in an optional embodiment, the first housing 11 is a trough structure with an opening on one side. A stepped portion 111 is provided on the side wall of the first housing. The stepped portion 111 includes a first stepped surface 1111, a second stepped surface 1112, and a stepped connecting surface 1113 located between the first stepped surface 1111 and the second stepped surface 1112. The first stepped surface 1111 is higher than the second stepped surface 1112. The guide rail is provided on the second stepped surface 1112. When the telescopic screen structure is in the retracted state, the side wall 121 of the second housing is flush with the surface of the first stepped surface 1111 and abuts against the stepped connecting surface 1113. The wall thickness of the side wall 121 of the second housing is equal to the difference in wall thickness between the first stepped surface 1111 and the second stepped surface 1112, so that the surface of the telescopic screen structure is smooth when in the retracted state, enhancing the aesthetics and sealing performance.

[0074] In an optional embodiment, the second housing 12 includes a connecting wall 122. The connecting wall 122 extends along the second direction from one end of the side wall 121 away from the first housing 11. The connecting wall 122 is arc-shaped and can better accommodate the second roller 223 when the telescopic screen structure is in the retracted state. The second housing 12 further includes an outer wall 123. The outer wall 123 is arranged along the first direction from the inner wall of the connecting wall 122. The wall thickness of the outer wall 123 is equal to the wall thickness of the side wall 121. The distance between the outer wall 123 and the side wall 121 along the second direction is equal to the thickness of the second stepped surface 1112. When the telescopic screen structure is in the retracted state, the outer wall 123 can be accommodated inside the housing 10, enhancing the overall sealing performance.

[0075] As Figure 2 、 Figure 4 、 Figure 6 、 Figure 9 and Figure 11 As shown, when the telescopic screen structure is in the retracted state, the first housing 11 and the second housing 12 are joined together. The first side plate 331 abuts against the part of the first support plate 31 provided with the first sub-slide rail 3111. The second side plate 333 abuts against the part of the second support plate 32 provided with the third sub-slide rail 3211. The bottom plate 332 abuts against the sides of the first support plate 31 and the second support plate 32 away from the opening. The second support plate 32 abuts against the first support plate 31. The movable support plate 33 is located on the sides of the first support plate 31 and the second support plate 32 away from the opening and is hidden below the first support plate 31 and the second support plate 32. The flexible display screen 40 covers the surfaces of the first support plate 31 and the second support plate 32 close to the opening.

[0076] When the telescopic screen structure switches from the retracted state to the deployed state, the driving member 21 drives the transmission member 22 to rotate. The transmission member 22 drives the second support plate 32 to move away from the first support plate 31. The second support plate 32 drives the second housing 12, the movable support plate 33, and the first end of the flexible display screen 40 to move away from the first support plate 31. During the movement, the second housing 12 gradually unfolds relative to the first housing 11. The first sliding member 334 of the movable support plate 33 slides along the first sub-rail 3111 and the first transition portion 3113. At the same time, the second sliding member 335 slides along the third sub-rail 3211 and the second transition portion 3213. The movable support plate 33 gradually exposes the gap between the first support plate 31 and the second support plate 32 and moves upward. The second end of the flexible display screen gradually moves out of the housing, so that the flexible display gradually unfolds and covers the support assembly 30.

[0077] As Figure 3 , Figure 10 and Figure 12 shown, when the first sliding member 334 slides into the second sub-rail 3112 and the second sliding member 335 slides into the fourth sub-rail 3212, the first side plate 331 abuts against the part of the first support plate 31 where the first sub-rail 3111 is not provided. The second side plate 333 abuts against the part of the second support plate 32 where the third sub-rail 3211 is not provided. The bottom plate 332 is located in the gap and abuts against the first support plate 31 and the second support plate 32. The surface of the bottom plate 332 close to the opening is flush with the surfaces of the first support plate 31 and the second support plate 32 close to the opening. The flexible display screen 40 covers the first support plate 31, the second support plate 32, and the surface of the bottom plate 332 close to the opening.

[0078] When the telescopic screen structure switches from the deployed state to the retracted state, the driving member 21 drives the transmission member 22 to rotate in the reverse direction. The transmission member 22 drives the second support plate 32 to move closer to the first support plate 31. The second support plate 32 drives the second housing 12, the movable support plate 33, and the first end of the flexible display screen 40 to move closer to the first support plate 31. During the movement, the second housing 12 gradually retracts relative to the first housing 11. The first sliding member 334 of the movable support plate 33 gradually slides from the second sub-rail 3112 to the first transition portion 3113 and the first sub-rail 3111. The second sliding member 335 gradually slides from the fourth sub-rail 3212 to the second transition portion 3213 and the third sub-rail 3211. The movable support plate 33 gradually moves downward to below the second support plate 32 and the first support plate 31. After the second support plate 32 and the first support plate 31 gradually approach and abut against each other, the movable support plate 33 is hidden below, and the second end of the flexible display screen gradually retracts into the housing 10.
