A display device

Abstract

This application relates to a display device, including a housing, a flexible screen, support plates, and limiting components. The flexible screen is rolled up inside the housing. Support plates are spaced apart on the backlight side of the flexible screen. Multiple limiting components are respectively installed on both sides of the support plates in the width direction and located between adjacent support plates. When the flexible screen is rolled up inside the housing, the limiting components are in a first state, and the angle between adjacent support plates changes with the flexible screen, allowing the flexible screen to be rolled up inside the housing. A protrusion is provided on the inner wall of the housing. The limiting components include a pushing member and a support column. When the flexible screen is outside the housing, the pushing member moves with the flexible screen, passing over the protrusion, so that the limiting component corresponding to the portion of the flexible screen extending out of the housing is in a second state. The support column extends between adjacent support plates to limit the relative position between adjacent support plates. When the flexible screen is rolled up inside the housing, the pushing member again passes over the protrusion, so that the limiting component corresponding to the portion of the flexible screen inside the housing returns to the first state.

Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a display device. Background Technology

[0002] Currently, some electronic devices incorporate flexible screens. When stored, the flexible screen rolls inside the casing, making the device easy to store. When in use, the flexible screen can be pulled out of the casing to display content, making the device suitable for various application scenarios. When the flexible screen is pulled out of the casing, the extended portion needs support to reduce the possibility of deformation affecting the display and touch functions. Existing support structures cannot provide support for the flexible screen when it is pulled out, and they bend along with the screen when it retracts. Summary of the Invention

[0003] This application provides a display device to solve the problem that the support structure cannot provide support when the flexible screen is pulled out, and bends with the flexible screen when the flexible screen is retracted.

[0004] This application provides a display device, the display device comprising:

[0005] case;

[0006] A flexible screen, which is rolled up inside the housing;

[0007] Multiple support plates are spaced apart on the backlight side of the flexible screen;

[0008] Multiple limiting components are respectively installed on both sides of the support plate along the width direction of the display device and located between adjacent support plates;

[0009] The inner wall of the housing has a protrusion, and the limiting component includes a pusher and a support column. When the flexible screen is inside the housing, the limiting component is in a first state, and the angle between adjacent support plates changes with the flexible screen. When the flexible screen is outside the housing, the pusher passes over the protrusion, the limiting component is in a second state, and the support column extends between adjacent support plates to limit the relative position between adjacent support plates. When the flexible screen is rolled up inside the housing, the pusher passes over the protrusion again, and the limiting component returns to the first state.

[0010] When the flexible screen is pulled out of the housing or retracted into the housing, the limiting components will pass through the protrusion. The pushing member passing over the protrusion can switch the limiting components between a first state and a second state. The limiting component corresponding to the part of the flexible screen that extends out of the housing is in the second state to support the flexible screen and reduce the possibility of deformation. At the same time, the limiting component corresponding to the part of the flexible screen that is inside the housing is in the first state. The angle between adjacent support plates can change with the flexible screen so that the flexible screen can be rolled up inside the housing.

[0011] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0058] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0059] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0061] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0062] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0063] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0064] like Figures 1 to 4As shown, this application provides a display device including a housing 1, a flexible screen, multiple support plates 2, and multiple limiting components 3. The flexible screen is rolled up inside the housing 1. The multiple support plates 2 are spaced apart on the backlight side of the flexible screen. The limiting components 3 are located between adjacent support plates 2, and along the width direction of the display device, the multiple limiting components 3 are respectively located on both sides of the support plates 2. The limiting components 3 include a pushing member 31 and a support column 32. When the flexible screen is rolled up inside the housing 1, the limiting components 3 are in a first state, and the angle between adjacent support plates 2 changes with the flexible screen, allowing the flexible screen to be rolled up inside the housing 1. The inner wall of the housing 1 is provided with a protrusion 11. When the flexible screen is outside the housing 1, the flexible screen needs to be pulled out of the housing 1. The pusher 31 will pass over the protrusion 11 with the flexible screen, so that the limiting component 3 is in the second state. At this time, the support column 32 extends into the space between the adjacent support plates 2 to limit the relative position between the adjacent support plates 2. When the flexible screen is rolled into the housing 1, the flexible screen retracts into the housing 1, the pusher 31 passes over the protrusion 11 again, and the limiting component 3 returns to the first state, so that the angle between the adjacent support plates 2 changes with the flexible screen, and the flexible screen can be rolled into the housing 1.

[0065] When the limiting component 3 is in the first state, the support column 32 does not extend between the adjacent support plates 2, and the relative position between the adjacent support plates 2 is not restricted. Therefore, the angle between the adjacent support plates 2 can change with the bending of the flexible screen, allowing the flexible screen to bend and be rolled up inside the housing 1, facilitating the storage of the display device. When the limiting component 3 is in the second state, the support column 32 extends between the adjacent support plates 2, restricting the relative position between the adjacent support plates 2, which can reduce the deformation of the flexible screen and affect the display and touch functions. When the flexible screen is pulled out of the housing 1 or retracted into the housing 1, it will pass through the protrusion 11, and the pusher 31 will pass over the protrusion 11, facilitating the switching of the limiting component 3 between the first and second states, so that the part of the flexible screen extending out of the housing 1 can be supported, reducing the possibility of deformation of the flexible screen, and the part of the flexible screen inside the housing 1 can be rolled up and stored.

[0066] like Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the support plate 2 includes a first limiting groove 21 located on opposite sides of two adjacent support plates 2. A support column 32 disposed between two adjacent support plates 2 can extend into the first limiting groove 21. The support column 32 includes a limiting portion 321 for limiting the relative position between the two support plates 2. The limiting portion 321 includes two first limiting protrusions 3211 with an included angle between them. When the limiting component 3 is in the second state, the two limiting protrusions extend into the first limiting groove 21 of the adjacent support plate 2.

[0067] Two limiting protrusions extend into the first limiting grooves 21 of two adjacent support plates 2, respectively, to limit the relative position between the support plate 2 and the limiting part 321, thereby limiting the relative position between adjacent support plates 2. Therefore, when the limiting component 3 is in the second state, the included angle between two adjacent support plates 2 is the same as the included angle between the two first limiting protrusions 3211. For example, if the included angle between the two first limiting protrusions 3211 is 180°, and the included angle between two adjacent support plates 2 is also 180°, the two first limiting protrusions 3211 in the limiting part 321 can extend into the first limiting grooves 21 of the two support plates 2, keeping the included angle between the two adjacent support plates 2 at 180° to support the flexible screen, keep the flexible screen flat, and reduce the possibility of bending.

[0068] like Figure 5 and Figure 7 As shown, in one possible embodiment, the limiting part 321 includes a second limiting protrusion 3212, which is located between two first limiting protrusions 3211. When the limiting component 3 is in the second state, the second limiting protrusion 3212 extends into the gap between adjacent support plates 2.

[0069] A second limiting protrusion 3212 is provided between the two first limiting protrusions 3211. The two second limiting protrusions 3212 and the two first limiting protrusions 3211 form a cross-shaped limiting structure. When the limiting component 3 is in the second state, the second limiting protrusion 3212 extends into the gap between the adjacent support plates 2, so that the two opposite surfaces of the two adjacent support plates 2 respectively abut against the surfaces on both sides of the second limiting protrusion 3212, further restricting the relative position between the two adjacent support plates 2, making the relative position of the two adjacent support plates 2 more stable.

[0070] like Figure 7 As shown, in one possible embodiment, the support column 32 further includes a connecting portion 322 and an abutting portion 323. One end of the connecting portion 322 is connected to the limiting portion 321, and the other end is connected to the abutting portion 323. The end of the abutting portion 323 away from the connecting portion 322 abuts against the pusher 31.

[0071] The abutting portion 323 in the support column 32 abuts against the pushing member 31, enabling the pushing member 31 to push the support column 32 to move. The abutting portion 323 is located on the side of the connecting portion 322 away from the limiting portion 321. When the pushing member 31 pushes the support column 32, the support column 32 can move in the direction of the connecting portion 322 pointing towards the limiting portion 321, so that the limiting portion 321 can extend between adjacent support plates 2 to limit the relative position between adjacent support plates 2.

[0072] like Figure 5 , Figure 7 and Figure 8As shown, the diameter of the connecting portion 322 in the support column 32 is smaller than the diameter of the limiting portion 321 and the abutting portion 323. The limiting component 3 includes an elastic member 33, which is sleeved on the connecting portion 322 and abuts against the abutting portion 323. The limiting component 3 also includes a sleeve 34, which is mounted on the support plate 2. The support column 32 and the pushing member 31 are both disposed inside the sleeve 34. The sleeve 34 includes a mounting portion 341, which protrudes from the inner wall of the sleeve 34. The end of the elastic member 33 away from the abutting portion 323 abuts against the mounting portion 341.

[0073] The sleeve 34 is mounted on the support plate 2 and extends along the width direction of the display device. The support column 32 and the pusher 31 are both disposed inside the sleeve 34. The sleeve 34 can limit the position of the support column 32 and the pusher 31 radially and allow the support column 32 and the pusher 31 to move axially along the sleeve 34. The sleeve 34 has an opening at one end mounted on the support plate 2 and at the end away from the support plate 2. The support column 32 can extend out of or retract from the sleeve 34 through the opening at the end mounted on the support plate 2. The pusher 31 can extend out of the sleeve 34 through the opening at the end away from the support plate 2. When the limiting assembly 3 switches from the first state to the second state, the pushing member 31 passes over the protrusion 11, causing it to move axially along the sleeve 34 towards the support plate 2, pushing the support column 32 to move towards the support plate 2, compressing the elastic member 33. The limiting part 321 in the support column 32 extends between adjacent support plates 2, and then the pushing member 31 engages with the sleeve 34, keeping the limiting assembly 3 in the second state. When the limiting assembly 3 switches from the second state to the first state, the pushing member 31 passes over the protrusion 11 again, causing the pushing member 31 to disengage from the sleeve 34, thereby releasing the force on the elastic member 33. The elastic member 33 resets, causing the support column 32 to move away from the support plate 2 until the limiting part 321 disengages from the support plate 2.

[0074] like Figure 5 , Figure 7 and Figure 8 As shown, in one possible embodiment, the distance between the mounting part 341 and the support plate 2 is greater than or equal to the length of the limiting part 321.

[0075] When the limiting component 3 is in the second state, the elastic element 33 is compressed, and the limiting part 321 extends out of the sleeve 34 and is located between adjacent support plates 2. When the limiting component 3 switches from the second state to the first state, the elastic element 33 resets, driving the support column 32 to retract into the sleeve 34. One end of the elastic element 33 sleeved on the connecting part 322 abuts against the mounting part 341, and the other end abuts against the abutting part 323. When the elastic element 33 resets, the end of the elastic element 33 that abuts against the mounting part 341 can also abut against the limiting part 321 of the support column 32. The distance between the mounting part 341 and the support plate 2 is greater than or equal to the length of the limiting part 321, so that the support column 32 can be completely retracted into the sleeve 34, and the limiting component 3 switches to the first state.

[0076] like Figure 5 As shown, in one possible embodiment, the sleeve 34 includes a first main body portion 342 and a second main body portion 343, which are respectively connected to two adjacent support plates 2, and there is a gap between the first main body portion 342 and the second main body portion 343.

[0077] The support column 32 and the pusher 31 are disposed inside the sleeve 34, and then the sleeve 34 is installed on the support plate 2. The first main body 342 and the second main body 343 of the sleeve 34 are provided with screw holes, so that the first main body 342 and the second main body 343 are installed on the support plate 2 by long screws. When the limiting component 3 is in the first state, the angle between adjacent support plates 2 changes with the flexible screen, and there is a gap between the first main body 342 and the second main body 343, so that the first main body 342 and the second main body 343 can move with the support plate 2, so that the flexible screen can be rolled up in the housing 1.

[0078] like Figure 5 , Figure 8 , Figure 9 and Figure 10 As shown, in one possible embodiment, the pusher 31 includes a first segment 311, one end of which abuts against the support column 32, and the other end is provided with multiple stepped surfaces 3111 and multiple second limiting grooves 3112, the second limiting grooves 3112 being located between adjacent stepped surfaces 3111. The inner wall of the sleeve 34 is provided with multiple third limiting protrusions 344. When the limiting component 3 is in the first state, the third limiting protrusions 344 extend into the second limiting grooves 3112, and when the limiting component 3 is in the second state, the third limiting protrusions 344 abut against the stepped surfaces 3111.

[0079] The sleeve 34 is internally provided with a third limiting protrusion 344, which is used to limit the position of the first segment 311 of the pusher 31 within the sleeve 34 along the width direction of the display device. When the limiting assembly 3 is in the second state, the third limiting protrusion 344 abuts against the stepped surface 3111, positioning the first segment 311 close to the support plate 2, which compresses the elastic member 33 and pushes the support column 32 into the space between adjacent support plates 2. When the limiting assembly 3 is in the first state, the third limiting protrusion 344 extends into the second limiting groove 3112. Under the action of the elastic member 33, the first segment 311 can move away from the support plate 2, and consequently, the support column 32 can also move away from the support plate 2, retracting into the sleeve 34 and releasing the engagement with the support plate 2.

[0080] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible embodiment, the step surface 3111 includes a first inclined surface 3111a and a second inclined surface 3111b. The inclination direction of the first inclined surface 3111a and the inclination direction of the second inclined surface 3111b are the same, both inclined towards the side where the first segment 311 abuts against the support column 32. The higher end of the first inclined surface 3111a communicates with the second limiting groove 3112 on one side of the step surface 3111; there is a height difference between the lower end of the first inclined surface 3111a and the higher end of the second inclined surface 3111b, and a vertical surface 3111c is formed between the lower end of the first inclined surface 3111a and the higher end of the second inclined surface 3111b; the lower end of the second inclined surface 3111b communicates with the second limiting groove 3112 on the other side of the step surface 3111. The pusher 31 also includes a second section 312, one end of which extends out of the sleeve 34, and the other end is provided with a plurality of toothed protrusions 3121. The toothed protrusions 3121 are correspondingly provided with the stepped surfaces 3111, with each stepped surface 3111 corresponding to one toothed protrusion 3121, and the toothed protrusions 3121 abutting against the stepped surfaces 3111. When the limiting component 3 is in the first state, the toothed protrusions 3121 abut against the first inclined surface 3111a, and when the limiting component 3 is in the second state, the toothed protrusions 3121 abut against the second inclined surface 3111b.

[0081] A third limiting groove 3122 is provided on the surface of the second segment 312, and a third limiting protrusion 344 on the inner wall of the sleeve 34 is located within the third limiting groove 3122, which allows the second segment 312 to move axially and reduces the possibility of the second segment 312 rotating within the sleeve 34. Figure 11As shown, a fourth limiting groove 3123 is also provided on the side of the second segment 312 facing the first segment 311. The end of the first segment 311 without the stepped surface 3111 extends into the fourth limiting groove 3123, which can limit the relative position of the first segment 311 and the second segment 312 in the radial direction, reducing the possibility that the toothed protrusion 3121 in the second segment 312 will detach from the stepped surface 3111 in the first segment 311. Furthermore, the first segment 311 can rotate relative to the second segment 312.

[0082] When the limiting component 3 is in the first state, the third limiting protrusion 344 extends into the second limiting groove 3112, and the toothed protrusion 3121 abuts against the middle position of the first inclined surface 3111a. When the flexible screen is pulled out of the housing 1, one end of the second segment 312 extending out of the sleeve 34 will pass over the protrusion 11. The protrusion 11 first applies a force to the second segment 312 in the direction of the support plate 2, causing the second segment 312 to push the first segment 311 towards the support plate 2. The first segment 311 pushes the support column 32, thereby compressing the elastic element 33. The elastic element 33, being compressed, generates elastic force that applies a force in the opposite direction to the first segment 311. When the first segment 311 moves to the point where the third limiting protrusion 344 disengages from the second limiting groove 3112, the force applied by the elastic element 33 to the first segment 311 will push the first segment 311 away from the support plate 2. At this time, the first segment 311 will rotate relative to the sleeve 34, causing... The toothed protrusion 3121 in the second segment 312 abuts against the vertical surface 3111c between the first inclined surface 3111a and the second inclined surface 3111b. At this time, the third limiting protrusion 344 is aligned with the first inclined surface 3111a. After the end of the second segment 312 extending from the sleeve 34 passes the protrusion 11, the force on the second segment 312 is released. Under the action of the elastic force generated by the elastic element 33, the first segment 311 continues to move away from the support plate 2. The movement causes the end of the third limiting protrusion 344 to abut against the first inclined surface 3111a. Then, it rotates within the sleeve 34, causing the third limiting protrusion 344 to apply force to the toothed protrusion 3121 in the second segment 312, causing the second segment 312 to disengage from the first inclined surface 3111a until the third limiting protrusion 344 abuts against the vertical surface 3111c between the first inclined surface 3111a and the second inclined surface 3111b. At this time, the limiting assembly 3 switches to the second state.

[0083] When the limiting component 3 is in the second state, the third limiting protrusion 344 abuts against the first inclined surface 3111a, and the toothed protrusion 3121 abuts against the second inclined surface 3111b. When the flexible screen retracts into the housing 1, one end of the second segment 312 extending out of the sleeve 34 will again pass over the protrusion 11. The protrusion 11 first applies a force to the second segment 312 in the direction of the support plate 2, causing the second segment 312 to push the first segment 311 towards the support plate 2, so that the third limiting protrusion 344 disengages from the first inclined surface 3111a and passes over the vertical surface 3111c. Since the toothed protrusion 3121 abuts against the second inclined surface 3111b at this time, under the action of the elastic force generated by the elastic element 33, the first segment 311 will rotate inside the sleeve 34, so that the third limiting protrusion 344 aligns with the second inclined surface 3111b; when the second segment 312 extends out of the sleeve 34... After passing the protrusion 11, the force on the second segment 312 is released. Under the action of the elastic force generated by the elastic member 33, the first segment 311 continues to move away from the support plate 2, causing the second segment 312 to pop out away from the support plate 2 and separate from the second inclined surface 3111b, so that the third limiting protrusion 344 abuts against the third inclined surface. Under the action of the elastic force generated by the elastic member 33, the first segment 311 continues to move away from the support plate 2. Since the third limiting protrusion 344 abuts against the third inclined surface, the first segment 311 will rotate inside the sleeve 34. The third limiting protrusion 344 will slide along the second inclined surface 3111b to the second limiting groove 3112 on the other side of the step surface 3111, so that the elastic force of the elastic member 33 can be fully released and the support column 32 can be completely retracted into the sleeve 34. At this time, the limiting assembly 3 switches to the first state.

[0084] like Figure 4 , Figure 10 and Figure 11 As shown, the second segment 312 of the pusher 31 includes a body portion 3124 and a pusher portion 3125. The pusher portion 3125 is located on one side of the body portion 3124, and the cross-sectional area of ​​the pusher portion 3125 is smaller than that of the body portion 3124. The toothed protrusion 3121 is located on the other side of the body portion 3124, and the third limiting groove 3122 is located on the side wall of the body portion 3124. The opening at the end of the sleeve 34 away from the support plate 2 is larger than the cross-sectional area of ​​the pusher portion 3125 but smaller than the cross-sectional area of ​​the body portion 3124. After the second segment 312 of the pusher 31 is installed on the sleeve 34, the pusher portion 3125 can extend out of the sleeve 34 from the opening at the end of the sleeve 34 away from the support plate 2, so that the pusher portion 3125 can contact the protrusion 11 to switch the state of the limiting component 3. At the same time, it can also reduce the possibility of the body portion 3124 disengaging from the sleeve 34 from the opening at the end of the sleeve 34 away from the support plate 2, thereby improving the reliability of the limiting component 3.

[0085] like Figure 1 and Figure 12As shown, the housing 1 includes an outlet 12, and a protrusion 11 is located inside the housing 1 near the outlet 12. The protrusion 11 includes a first guide surface 111 and a second guide surface 112, both of which are inclined toward each other, and the second guide surface 112 is located on the side near the outlet 12.

[0086] When the flexible screen is pulled out of the housing 1, the second segment 312 in the pusher 31 contacts the first guide surface 111. As the limiting component 3 is pulled out of the housing 1 along with the flexible screen, the second segment 312 moves along the first guide surface 111. Under the action of the first guide surface 111, it moves towards the support plate 2, thereby pushing the first segment 311 and the support column 32 towards the support plate 2, until the third limiting protrusion 344 in the sleeve 34 disengages from the second limiting groove 3112 and abuts against the stepped surface 3111 in the first segment 311. The second segment 312 passes over the protrusion 11, the limiting component 3 switches to the second state, and the support column 32 extends between the adjacent support plates 2. The support plate 2 can support the flexible screen and reduce the possibility of the flexible screen bending. When the flexible screen retracts into the housing 1, the pusher 31 first contacts the second guide surface 112. During the process of the limiting component 3 retracting into the housing 1 along with the flexible screen, the second segment 312 moves along the second guide surface 112. Under the action of the second guide surface 112, it moves towards the support plate 2, thereby pushing the first segment 311 and the support column 32 towards the support plate 2, until the third limiting protrusion 344 in the sleeve 34 aligns with the second limiting groove 3112. The second segment 312 passes over the protrusion 11. Under the action of the elastic component 33, the support column 32 retracts into the sleeve 34, releasing the limitation on the support plate 2. The angle between the support plates 2 can change with the bending of the flexible screen, so that the flexible screen can be rolled up inside the housing 1.

[0087] When the limiting component 3 switches from the first state to the second state, along the width direction of the display device, the second segment 312 needs to push the first segment 311 a distance L1 towards the support plate 2, so that the third limiting protrusion 344 disengages from the second limiting groove 3112. When the limiting component 3 switches from the second state to the first state, along the width direction of the display device, the second segment 312 needs to push the first segment 311 a distance L2 towards the support plate 2, so that the third limiting protrusion 344 disengages from the first inclined surface 3111a of the step surface 3111 in the first segment 311 and crosses the vertical surface 3111c. Since the length of the second limiting groove 3112 is greater than the length of the vertical surface 3111c of the step surface 3111 in the first segment 311, the movement distance L1 of the first segment 311 when the limiting component 3 switches from the first state to the second state is greater than the movement distance L2 of the first segment 311 when the limiting component 3 switches from the second state to the first state. The height L of the protrusion 11 is greater than or equal to the movement distance L1 of the first segment 311 when the limiting component 3 switches from the first state to the second state, so that the limiting component 3 can switch from the first state to the second state.

[0088] The end of the pushing part 3125 away from the main body 3124 extends out of the sleeve 34 to contact the protrusion 11 and move along the first guide surface 111 and the second guide surface 112 of the protrusion 11, so that the second segment 312 pushes the first segment 311 towards the support plate 2 as it passes over the protrusion 11. Figure 10 As shown, the cross-section of the end of the pushing part 3125 away from the main body part 3124 is arc-shaped, which facilitates the movement of the pushing part 3125 along the first guide surface 111 and the second guide surface 112, reducing the force required when the flexible screen is pulled out or retracted from the housing 1.

[0089] like Figure 2 and Figure 12 As shown, along the width direction of the display device, two opposite side walls inside the housing 1 are provided with protrusions 11. When the flexible screen extends or retracts from the housing 1, the pushing members 31 in the limiting components 3 located on both sides of the flexible screen can pass over the protrusions 11 to switch the state of the limiting components 3.
