Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] It should also be understood that the terminology used in this utility model specification is merely for describing specific aspects of the present application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] like Figures 1 to 6 As shown, this application provides a roller shutter screen, including a roller 200 and a flexible screen 100. One end of the flexible screen 100 is connected to the roller 200 and can be rolled around the roller 200 to facilitate storage when not in use and to pull out from the roller 200 when in use. The structure is simple and compact, easy to carry and use, adaptable, safe and reliable.

[0045] In an optional embodiment, the flexible screen 100 includes multiple unit modules 10 and a connecting mechanism 20 connecting two adjacent unit modules 10. A central control component 300 is provided inside the scroll 200. The central control component 300 is electrically connected to the unit modules 10 to realize the transmission of power and / or signals, so that the multiple unit modules 10 can obtain display data or parameter data from the central control component 300. The central control component 300 is mainly used to receive display data or parameter data and control the display screen of the control module 10 according to the display data or parameter data. In this application, the central control component 300 is built into the scroll 200. This not only reduces the weight of the unit module 10 and the load-bearing load of the scroll 200 from top to bottom, making it easier for the flexible screen 100 to roll up or unfold around the scroll 200; it also greatly reduces the size of the roller screen and the space occupied by the central control component 300. It eliminates the need to place the central control component 300 outside the roller screen, which can ensure the normal operation of the roller screen, reduce the workload of operators in installing the roller screen, reduce their workload, and save installation time. It solves the pain points of deployment efficiency and size of roller screens, and is especially suitable for space-sensitive scenarios such as commercial displays and vehicle displays.

[0046] For example, the roller shutter screen has a rolled-up state and an unfolded state, and can switch between the two states. When the roller shutter screen is in the rolled-up state, the flexible screen 100 is rolled around the roller shaft 200 to form a cylindrical shape, and all the unit modules 10 are stacked together in sequence, greatly reducing the volume of the roller shutter screen. The structure is simple and compact, easy to carry and use, adaptable, safe and reliable. When the roller shutter screen is in the unfolded state, the flexible screen 100 unfolds into a plane, and all the unit modules 10 are arranged in a straight line on one side of the roller shaft 200, which facilitates the display of images on the flexible screen 100. Especially when the roller shutter screen is suspended by the roller shaft 200, the flexible screen 100 can be straightened into a planar structure during the descent and under its own gravity.

[0047] It should be noted that the connecting mechanism 20 has a certain degree of flexibility to allow the flexible screen 100 to maintain the coordinated operation between the unit modules 10 when it is rolled up. This not only adapts to bending stress but also ensures the stability of power and signal transmission during the rolling process.

[0048] In an optional embodiment, the central control component 300 includes at least one of a battery component, a communication module, and a control card. A hollow cavity 2011 is formed within the roller 200, and at least one of the battery component, communication module, and control card is disposed within the hollow cavity 2011. This prevents the central control component 300 from being external to the roller shutter screen or indirectly disposed within the unit module 10, allowing the weight of the flexible screen 100 to be distributed, reducing the load on the flexible screen 100, extending the service life of the flexible screen 100, and also increasing the safety of the roller shutter screen. In an optional embodiment, the unit module 10 has a display surface and a non-display surface arranged opposite each other. The connecting mechanism 20 connects two adjacent non-display surfaces. When the display surface is rolled up, it faces the side opposite to the scroll 200. This not only ensures that the unit module 10 can be electrically connected to the central control component 300 inside the scroll 200 through the non-display surface, but also reduces the pressure on the display surface when it is rolled up. That is, when the flexible screen 100 is rolled around the scroll 200, the non-display surface of the unit module 10 first contacts the scroll 200 or the inner unit module 10 to form a larger radius of curvature. This reduces the pressure wrinkles on the screen surface, ensuring that the scroll with a larger outer diameter can smoothly transition the surface of the unit module 10 during the rolling and unfolding of the unit module 10, preventing deformation of the unit module 10, and thus extending the service life of the unit module 10. In addition, the signal connection line 30 between the unit modules 10 is located on the non-display surface. When rolled up, the signal connection line 30 is stretched and concentrated on the non-display surface to protect the visual integrity of the display surface.

[0049] In one optional embodiment, the unit module 10 includes a module base shell and a lamp plate with LED beads. Both the module base shell and the lamp plate are flexible, bendable structures. The lamp plate is mounted on the module base shell, and the module base shells are interconnected by a connecting mechanism 20. The module base shell can be made of glass fiber reinforced PC material to withstand the bending stress of the unit module 10, thereby protecting the lamp plate.

[0050] It should be noted that the unit module 10 can be, but is not limited to, a COB module or a GOB module, and this application does not impose any restrictions.

[0051] In one optional embodiment, a first connecting portion is provided on the non-display surface. The end of the connecting mechanism 20 near the scroll 200 is fixedly connected to the first connecting portion, and the end of the connecting mechanism 20 away from the scroll 200 is movably connected to the first connecting portion. This reduces interference between unit modules 10 during the rolling process of the flexible screen 100, thereby achieving dynamic stress distribution and improved mechanical reliability of the flexible screen 100 during the rolling process.

[0052] In one alternative implementation, such as Figures 6 to 9As shown, the connecting mechanism 20 has a first mounting hole 21 and a second mounting hole 22 extending along the length direction, which are arranged opposite to each other. The first mounting hole 21 is fixedly connected to the non-display surface on the side close to the scroll 200, and the second mounting hole 22 is movably connected to the non-display surface on the side away from the scroll 200. This solves the problem that the gap between the upper and lower unit modules 10 cannot be adjusted during the rolling process of the flexible screen 100, and achieves a precise balance between mechanical constraints and degree of freedom during the rolling process.

[0053] For example, such as Figure 3 , Figures 6 to 9 As shown, the unit module 10 includes a first unit module 11 located above and a second unit module 12 located below. The first connecting part of the first unit module 11 is fixedly connected to the first mounting hole 21, and the first connecting part of the second unit module 12 is movably connected to the second mounting hole 22 and can move along the length direction of the second mounting hole 22, so that the second unit module 12 and the first unit module 11 can have a certain amount of movement during the rolling process of the flexible screen 100, thereby reducing the interference between the second unit module 12 and the first unit module 11.

[0054] In an optional embodiment, the roller shutter screen includes a fall prevention component 400, which is disposed at one or both ends of the roller 200. The fall prevention component 400 is used to prevent the roller 200 from rotating in a preset direction, thereby preventing the flexible screen 100 from falling during the process of the roller 200 driving the flexible screen 100 from the unfolded state to the retracted state. This achieves a dynamic balance between the function of the flexible screen 100 and the fall prevention component 400 during the process of switching to the retracted state, maintaining and assisting the flexible screen 100 in the unfolded state and always preventing it from falling. This is an optimization of the roller shutter screen during operation and effectively solves the risk of the flexible screen 100 falling during the dynamic retracting process.

[0055] In an optional embodiment, the fall arrestor 400 includes a fall arrestor pawl 402 fixedly connected to a fall arrestor ratchet 401. The fall arrestor pawl 402 is located on one side of the fall arrestor ratchet 401 and is used to cooperate with the fall arrestor ratchet 401 to limit the fall arrestor ratchet 401 to rotate in only one direction. This achieves directional control of the rotation of the reel 200 through mechanical one-way locking, eliminating the need for additional force from the operator and reducing labor intensity.

[0056] For example, through the above design, when the scroll 200 drives the flexible screen 100 from the unfolded state to the retracted state, the anti-fall pawl 402 engages with the ratchet teeth on the anti-fall ratchet 401 to prevent the flexible screen 100 from sliding down due to an accident. Thus, under the action of the anti-fall pawl 402 and the anti-fall ratchet 401, the scroll 200 can only rotate in one direction to prevent the flexible screen 100 from continuing to slide down; that is, the anti-fall ratchet 401 can only rotate clockwise. When the scroll 200 drives the flexible screen 100 from the retracted state to the unfolded state, the anti-fall pawl 402 and the ratchet teeth of the anti-fall ratchet 401 disengage to release the restriction on the rotation direction of the scroll 200, allowing the scroll 200 to rotate freely. That is, the anti-fall ratchet 401 can rotate clockwise or counterclockwise, thereby allowing the flexible screen 100 to be lowered and unfolded.

[0057] In an optional embodiment, the roller shutter screen includes a drive assembly 500, which is connected to the roller 200 for driving the roller 200 to switch the flexible screen 100 between an unfolded state and a retracted state.

[0058] In an optional embodiment, the drive assembly 500 includes a first pulley 501, a second pulley 502, and a belt 503. The first pulley 501 is connected to the reel 200, the second pulley 502 is spaced apart from the first pulley 501, and the belt 503 is sleeved between the first pulley 501 and the second pulley 502. The second pulley 502 is connected to a built-in or external drive motor, so that the drive motor can drive the second pulley 502 to rotate clockwise or counterclockwise. When the second pulley 502 rotates clockwise, the second pulley 502 drives the first pulley 501 to rotate clockwise through the belt 503, so as to switch the flexible screen 100 from the unfolded state to the retracted state. At this time, the anti-fall pawl 402 engages with the ratchet teeth on the anti-fall ratchet 401 to prevent the flexible screen 100 from sliding down due to an accident on the reel 200. When the second pulley 502 rotates counterclockwise, the second pulley 502 drives the first pulley 501 to rotate counterclockwise via the belt 503, so as to switch the flexible screen 100 from the winding state to the unfolding state. At this time, the anti-fall pawl 402 separates from the ratchet on the anti-fall ratchet 401, releasing the restriction on the rotation direction of the first pulley 501 or the reel 200, allowing the first pulley 501 or the reel 200 to rotate counterclockwise.

[0059] In an optional embodiment, the anti-fall pawl 402 is connected to the belt 503 for transmission, and can control the anti-fall pawl 402 to separate from the anti-fall ratchet 401 when the belt 503 drives the reel 200 to descend and the flexible screen 100 is lowered, and control the anti-fall pawl 402 to engage with the anti-fall ratchet 401 when the flexible screen 100 is rolled up, so as to prevent the reel 200 from accidentally causing the flexible screen 100 to slide down.

[0060] For example, the fall arrestor assembly 400 further includes a support member and an elastic member. The fall arrestor pawl 402 is rotatably mounted on the support member, and both ends of the elastic member abut against the fall arrestor pawl 402 and the support member, respectively, so that the fall arrestor pawl 402 always remains separated from the ratchet teeth on the fall arrestor ratchet 401. The fall arrestor assembly 400 also includes a transmission member 403, which is connected to the fall arrestor pawl 402 and is used to overcome the elastic force of the elastic member, so that the fall arrestor pawl 402 engages with the ratchet teeth on the fall arrestor ratchet 401.

[0061] Specifically, belt 503 has an upper belt portion 5032 and a lower belt portion 5031. When the second pulley 502 rotates clockwise, the upper belt portion 5032 is taut, and the transmission member 403 contacts the upper belt portion 5032, thereby applying an upward force arm to the transmission member 403. This allows the transmission member 403 to apply a force arm towards the anti-fall pawl 402 towards the anti-fall ratchet 401, ensuring that the anti-fall pawl 402 engages with the ratchet teeth on the anti-fall ratchet 401. When the second pulley 502 rotates counterclockwise, the lower belt portion 5031 is taut, and the upper belt portion 5032 is not subjected to tension or strain and is in a naturally drooping state. The transmission member 403 separates from the upper belt portion 5032, and the anti-fall pawl 402 separates under the action of the elastic member.

[0062] In an optional embodiment, the fall arrestor 400 includes a second drive member for controlling the fall arrestor pawl 402 to separate from the fall arrestor ratchet 401 when the flexible screen 100 is descending, and controlling the fall arrestor pawl 402 to engage with the fall arrestor ratchet 401 when the flexible screen 100 is curling, so as to prevent the flexible screen 100 from sliding down due to an accident caused by the roll 200.

[0063] In an optional embodiment, the reel 200 includes a shaft 201 and connecting ends 202 disposed at both ends of the shaft. A hollow cavity 2011 is formed inside the shaft 201, and a mounting cavity is formed inside the connecting end 202. The anti-fall assembly 400 and the drive assembly 500 are mounted in the mounting cavity.

[0064] In one optional embodiment, the ratio of the diameter of the shaft 201 to the width of the unit module 10 is in the range of 3 to 5, so that the surface of the unit module 10 can smoothly transition during the use of rolling and unrolling, preventing deformation of the unit module 10 and thus extending the service life of the unit module 10. In one optional embodiment, the flexible screen 100 is provided with a protective edge 40. The protective edge 40 is used to protect the edge of the flexible screen 100. It can provide support for both sides of the flexible screen 100 in the width direction in either the unfolded or rolled-up state, thereby protecting the flexible screen 100 and reducing the probability of wrinkles and cracks in the flexible screen 100 during frequent unfolding and rolling, thus extending the service life of the flexible screen 100.

[0065] In an optional embodiment, the flexible screen 100 includes a connecting piece 50, which connects two adjacent unit modules 10 together in the width direction. This connecting piece 50 can be used to improve and control the gap between the two unit modules 10 during splicing, and can also provide some support during the rolling process of the flexible screen 100.

[0066] In one optional embodiment, a protective cover is mounted on the display surface of the flexible screen 100. The protective cover covers the outside of the LED beads of the flexible screen 100. The protective cover can be straightened under the gravity of the unit module 10, thereby unfolding into a planar state. The protective cover includes, but is not limited to, a flexible steel mesh.

[0067] In one alternative implementation, such as Figures 10 to 11 As shown, the connecting mechanism 20 includes a connecting strip 20a. A bottom shell groove 10a is formed on the non-display surface. The connecting strip 20a is fixed in the bottom shell groove 10a, so that multiple unit modules 10 can be connected to each other through the connecting strip 20a to ensure the stability of the connection between the unit modules 10. The connecting strip 20a includes, but is not limited to, a steel strip. The steel strip can also connect the unit modules 10 to the roll 200, and this application does not limit this.

[0068] In an optional embodiment, the bottom shell groove 10a is provided with a positioning hole and / or a third mounting hole. The positioning hole is used to realize the positioning and installation of the unit module 10 and the connecting strip 20, and the third mounting hole is used to realize the stable connection between the unit module 10 and the connecting strip 20.

[0069] In an optional embodiment, the flexible screen 100 also includes steel wire ropes disposed on both sides of the flexible screen 100 to assist the flexible screen 100 in curling and unfolding, and to provide a tension force for the flexible screen 100 when unfolding, so as to ensure the safety and reliability of the flexible screen 100 when suspended.

[0070] In one optional embodiment, the non-display surface of the unit module is provided with at least a soft adhesive layer so that the flexible screen 100 will not damage the display surface during the rolling and unfolding process. The soft adhesive layer can be formed by spraying silicone onto the non-display surface, or the silicone can be sprayed entirely onto the non-display surface, or the silicone can be sprayed horizontally or vertically to form a strip shape; this application does not impose any limitations.

[0071] In one alternative embodiment, the two ends of the reel 200 are fixed to the mounting frame or building; or the two ends of the reel 200 are fixed to the mounting frame or building by means of suspension points, which is not limited in this application.
