Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Large LED display screens are generally used for large-area display and projection. They are generally large in size. The total display screen usually needs to be realized by splicing multiple individual display panels. It is difficult to realize curved display on such large-area LED display screens. In the prior art, large LED display screens are made by rotating and connecting multiple mounting plates, and then installing the display screens one-to-one on the mounting plates, so that the entire display screen visually appears to be bent; but the screen itself is actually not bent, and the bending angles between the multiple mounting plates are relatively limited, which makes the overall angle adjustment of the screen less free.

[0032] The present invention provides a flexible and bendable LED display screen 100 .

[0033] See also Figure 1-9In one embodiment of the present invention, the flexible bendable LED display screen 100 includes: a frame assembly 1, a support assembly 3 and an LED display screen 4; the frame assembly 1 includes a first frame 11 and a second frame 12, and the second frame 12 is rotatably connected to the first frame 11 through a connecting mechanism 2; the support assembly 3 is arranged on one side of the frame assembly 1, and the first frame 11 and the second frame 12 change the shape of the support assembly 3 through relative rotation; the LED display screen 4 is arranged on the side of the support assembly 3 away from the frame assembly 1, and the LED display screen 4 can bend as the shape of the support assembly 3 changes.

[0034] In this embodiment, the frame assembly 1 is a supporting structure of the flexible and bendable LED display screen 100, and the frame assembly 1 includes a first frame 11 and a second frame 12. Among them, the first frame 11 is the main supporting structure, and the overall strength is relatively high. In addition to being used to support the second frame 12, the first frame 11 also has an installation cavity for installing circuit elements. The circuit elements are used to realize the circuit control function of the flexible and bendable LED display screen 100, so that operations such as controlling screen display or angle adjustment can be performed autonomously according to a preset method; after the circuit elements are arranged in the installation cavity, the opening of the installation cavity is covered by the cover body so that the circuit elements are installed in the installation cavity without falling out, and dust is prevented from entering and damaging the operation of the circuit elements. The second frame 12 is set to a structure with a hollow middle and a high outer contour strength, so that the second frame 12 is light in weight, so that it can be flexibly rotated on the first frame 11, and at the same time, it has a certain strength to cooperate with the first frame 11 to fix the support assembly 3. The first frame 11 and the second frame 12 are rotatably connected by the connecting mechanism 2. One end of the connecting mechanism 2 is fixedly installed on the first frame 11 by a threaded fastener, and the other end is fixedly installed on the second frame 12 by a threaded fastener, so that each structure is easy to disassemble and maintain. At the same time, each structure is connected by a threaded fastener. The frame assembly 1 can be first split into multiple structures for transportation, and then transported to a suitable location for installation to reduce transportation costs. In this embodiment, the LED display screen 4 uses a flexible material as a substrate, so that the screen itself can be bent, folded or stretched to adapt to a variety of installation surfaces and shapes; the support assembly 3 is used to transform different curved surfaces and shapes through permutations and combinations and its own bending, so that the LED display screen 4 installed on its surface shows curved surfaces of different angles and shapes as the surface shape of the support assembly 3 changes.

[0035] In the present embodiment, two second frames 12 are specifically provided, and the two second frames 12 are rotatably connected to the two ends of the first frame 11 respectively, and the two second frames 12 are rotatably connected to the two sides of the first frame 11 respectively through connecting pieces, so that the frame assembly 1 can rotate at a larger angle, and can be adjusted into curved surfaces of more shapes through one frame assembly 1; in other embodiments, when the flexible bendable LED display screen 100 does not need to be adjusted into a too complex curved surface, only one second frame 12 can be rotatably connected to the first frame 11 to reduce the overall mass of the flexible bendable LED display screen 100. After the frame assembly 1 is assembled, the support assembly 3 is installed on one side of the frame assembly 1. The side of the support assembly 3 facing away from the frame assembly 1 is a planar structure, and the LED display screen 4 can be installed on this side to be flattened; the support assembly 3 can change the curved surface shape of the outer surface as the second frame 12 in the frame assembly 1 rotates relative to the first frame 11, so that the flexible LED display screen 4 shows different curved surface shapes according to the shape of the outer surface of the support assembly 3. See. Figure 8-9 , Figure 8-9 These are two of the forms of multiple flexible bendable LED display screens 100 being spliced ​​together. When the screen display area of ​​a single flexible bendable LED display screen 100 is insufficient, multiple flexible bendable LED display screens 100 can be arranged and combined as needed, so that the display interfaces of multiple LED display screens 4 are connected in sequence to form a large display interface. At the same time, multiple flexible bendable LED display screens 100 themselves can be bent as needed, and multiple flexible bendable LED display screens 100 can be spliced ​​at different angles and fixed on a building surface or a preset rack on a site, thereby forming a large-scale LED curved display screen that can flexibly change the shape of the curved surface.

[0036] The technical solution of the present invention is to set a frame component 1 and a support component 3 arranged on one side of the frame component 1 in a flexible and bendable LED display screen 100, set a first frame 11 and a second frame 12 in the frame component 1, and connect the first frame 11 and the second frame 12 through a connecting mechanism 2, so that the first frame 11 and the second frame 12 can rotate relative to each other, thereby changing the shape of the support component 3, and the support component 3 can drive the LED display screen 4 installed on one side of the support component 3 to bend as needed. The flexible and bendable LED display screen 100 can achieve stepless adjustment of the LED display screen 4 through the connecting mechanism 2, so that the curvature adjustment of the flexible and bendable LED display screen 100 is more flexible.

[0037] In one embodiment, the frame assembly 1 has two second frames 12, and the two second frames 12 are relatively arranged at two ends of the first frame 11. In this embodiment, the two second frames 12 can rotate toward the same side relative to the first frame 11, so that the LED display screen 4 forms an arc structure that is concave or convex toward the side away from the frame assembly 1, and the two second frames 12 can also rotate toward the opposite side relative to the first frame 11, so that the LED display screen 4 forms an S-shaped curved surface.

[0038] See also Figure 3 , 4 In one embodiment, the support assembly 3 includes: a connecting piece 31 and a plurality of mounting plates 32; the connecting piece 31 is installed on one side of the frame assembly 1, the connecting piece 31 is extended along the first direction, the connecting piece 31 is fixedly connected to the first frame 11 and the second frame 12, and when the second frame 12 rotates relative to the first frame 11, the connecting piece 31 can bend along the rotation direction of the second frame 12 relative to the first frame 11; the plurality of mounting plates 32 are used to install the LED display screen 4, the mounting plate 32 is installed on the side of the connecting piece 31 away from the frame assembly 1, the mounting plate 32 is extended along the second direction, the plurality of mounting plates 32 are arranged along the first direction, the plurality of mounting plates 32 are installed on the frame assembly 1 through the connecting piece 31, and the first direction intersects with the second direction. In this embodiment, the first direction is the horizontal direction, and the second direction is the vertical direction. The connecting piece 31 is a flat and long strip metal sheet, which is extended in the horizontal direction. The length of the strip metal sheet is greater than or equal to the horizontal width of the frame assembly 1, so that when the strip metal sheet is installed on the frame assembly 1, its length can reach both ends of the frame assembly 1, and the middle section of the strip metal sheet can be fixed to the first frame 11, and the two ends can be fixed to the second frame 12, so that it can be connected and fixed to both the first frame 11 and the second frame 12 at the same time. In this way, when the second frame 12 rotates relative to the first frame 11, the two ends of the strip metal sheet can deflect relative to the middle section under the action of the second frame 12, thereby forming a curved shape. In other embodiments, when only one second frame 12 is provided to be rotatably connected to the first frame 11, the two ends of the mounting strip are respectively connected to the first frame 11 and the second frame 12, and the mounting strip can only be bent into an arc structure, and does not form an S-shaped structure. The mounting plate 32 is arranged in the vertical direction. The mounting plate 32 is a relatively hard metal plate that is not easy to bend. A plurality of mounting plates 32 are arranged along the extension direction of the mounting strip and are connected and fixed to the mounting strip by fasteners. When the mounting strip is bent, the plurality of mounting plates 32 are arranged along the curve of the mounting strip, and finally drive the LED display screen 4 to bend to form a preset curved surface.

[0039] In one embodiment, the connecting piece 31 is provided with a plurality of mounting positions for mounting the mounting plate 32 along the first direction, and the plurality of mounting plates 32 are installed one by one at the mounting positions; two mounting holes 311 for fasteners to pass through are provided on each mounting position, and the two mounting holes 311 are arranged at intervals along the first direction; and the connecting piece 31 is provided with a plurality of mounting holes 311 at intervals along the second direction. The mounting holes 311 are in the shape of a long strip, and the long strip holes are arranged extending along the length direction of the connecting piece 31. When the connecting piece 31 is bent, the connecting piece 31 will be subjected to force to form an arc structure, and the outer side of the annular structure is stretched and the inner side of the arc is compressed. When the connecting piece 31 is in a straight state, the plurality of mounting plates 32 closely arranged will be displaced due to the stretching or compression of the connecting piece 31 when the connecting piece 31 is bent. Therefore, the mounting holes 311 are provided in the shape of a long strip, so that when the mounting plate 32 is installed on the connecting piece 31 through the fasteners through the mounting holes 311, there is a certain space for the mounting plate 32 to adjust, so as to prevent the mounting plate 32 from being stretched or squeezed and crushed due to the bending of the connecting piece 31. In this embodiment, each mounting plate 32 is installed with the connecting piece 31 through a mounting hole 311 group. Each mounting hole 311 group has two mounting holes 311. Each mounting plate 32 is fixed with the connecting piece 31 through two mounting holes 311 at the same time, so as to better control the angle of the mounting plate 32 so that the final curve of the flexible bendable LED display screen 100 is smoother. The number of mounting holes 311 in the mounting hole 311 group can also be increased or decreased according to the quality of the mounting plate 32 or the curvature requirement of the flexible bendable LED display screen 100 to adapt to flexible bendable LED display screens 100 with different requirements. In this embodiment, four connecting pieces 31 are arranged at intervals along the second direction, and two rows of mounting plates 32 are arranged along the second direction. In each row of mounting plates 32, multiple mounting plates 32 are arranged along the extension direction of the connecting pieces 31, and each row of mounting plates 32 is respectively connected to every two connecting pieces 31, so that the mounting plates 32 can be installed more stably and the display area of ​​the flexible LED display screen 100 can be larger. The number and length of the mounting strips, the number of arrangements of the mounting plates 32, and the number of rows can be increased or decreased as needed.

[0040] See also Figure 1 , 56. In one embodiment, the connection mechanism 2 includes a connection shaft 22 and two connection components 21. The two connection components 21 are arranged opposite to each other along the second direction. The two connection components 21 are synchronously connected through the connection shaft 22 so that the two connection components 21 move synchronously. The connection mechanism 2 is provided with two connection components 21. The two connection components 21 are arranged at intervals along the height direction to balance the center of gravity of the flexible and bendable LED display screen 100, so that the movement of the flexible and bendable LED display screen 100 is more stable. The two connection components 21 can be linked through the connection shaft 22, so that the connection mechanism 2 can drive the structure of the two connection components 21 to adjust at the same time through only one connection shaft 22, and the two connection components 21 rotate at the same angle, thereby driving the second frame 12 to rotate only, and will not tilt due to the inconsistent rotation angles of the two connection components 21. In other embodiments, the number of connection components 21 can also be increased or decreased according to the actual weight of the flexible and bendable LED display screen 100. It is only necessary for multiple connection components 21 to be transmission-connected to the same connection shaft 22 to achieve the synchronous adjustment of multiple connection components 21.

[0041] See also Figure 1 , 5 6. In one embodiment, the connection assembly 21 includes a first connection member 211 and a second connection member 212, and the first connection member 211 and the second connection member 212 are rotatably connected; one end of the first connection member 211 away from the second connection member 212 is connected to the first frame 11, and one end of the second connection member 212 away from the first connection member 211 is connected to the second frame 12. The first connection member 211 is fixedly connected to the first frame 11 by a threaded fastener, and the second connection member 212 is fixedly connected to the second frame 12 by a threaded fastener. The first connection member 211 and the second connection member 212 rotate relative to each other, so that the first frame 11 connected to the first connection member 211 and the second frame 12 connected to the second connection member 212 rotate relative to each other, thereby changing the final angle of the first frame 11 and the second frame 12. When at least two connection assemblies 21 are arranged at intervals along the second direction, a connecting metal plate or metal rod for transmission can also be arranged between two adjacent first connection members 211 or second connection members 212, so that the structure of multiple connection assemblies 21 that need to move synchronously is more stable when moving.

[0042] See also Figure 6 , 7In one embodiment, the first connecting member 211 and the second connecting member 212 are arranged at intervals along the second direction, and the second connecting member 212 is provided with a first slide groove 212a on a side close to the first connecting member 211, and the first slide groove 212a is extended in an arc shape along the rotation direction of the second frame 12 relative to the first frame 11; a limiting column 211a is provided on a side of the first connecting member 211 close to the second connecting member 212, and the limiting column 211a can be slidably arranged in the first slide groove 212a. In this embodiment, the movement trajectory of the limiting column 211a in the limiting groove is an arc shape, and the circle where the arc is located is the first base circle; the second connecting member 212 is provided with two first slide grooves 212a, and the two first slide grooves 212a are arranged at intervals on the first base circle along the rotation direction, and the normal line of the first base circle is the base axis around which the second connecting member 212 rotates, and the two first slide grooves 212a extend along the same arc and are coaxially arranged on the circumference of the base circle. The first connecting member 211 is provided with a limiting column 211a corresponding to the first sliding groove 212a, and the limiting column 211a is cylindrical, and the cross-sectional diameter of the cylinder is adapted to the width of the first sliding groove 212a, so that the limiting column 211a can slide along a fixed track, that is, the track of the first base circle in the sliding groove, thereby driving the first connecting member 211 and the second connecting member 212 to rotate relative to each other. The track of the limiting column 211a moving in the first sliding groove 212a is the same as the rotation direction of the second frame 12 relative to the first frame 11.

[0043] In one embodiment, a dial 211b is provided on the side of the first connecting member 211 away from the supporting assembly 3, and the dial has a plurality of saw teeth, and the plurality of saw teeth are arranged along the rotation direction of the second frame 12 relative to the first frame 11. The connecting assembly 21 also includes a gear 213 that cooperates with the saw teeth, and the gear 213 can be rotatably installed on the second connecting member 212; the connecting shaft 22 transmits the connecting gear 213 to drive the second connecting member 212 and the first connecting member 211 to rotate relative to each other through the gear 213. In this embodiment, a gear 213 groove matching the outer diameter of the gear 213 is provided on the side of the second connecting member 212 facing the first connecting member 211, and the gear 213 can be rotatably installed in the gear 213 groove. The gear 213 is meshed and connected with the dial 211b. After meshing, the gear 213 rolls on the outer periphery of the dial 211b under the action of external force. The dial 211b is arranged in an arc shape on the side of the first connecting member 211 away from the supporting assembly 3, and the arc extends along the rotation direction of the second frame 12 relative to the first frame 11. At this time, the movement trajectory of the gear 213 on the dial 211b is also an arc shape. Assuming that the full circle where the arc is located is the second base circle, the normal of the second base circle coincides with the normal of the aforementioned first base circle, that is, the second base circle is coaxially arranged with the aforementioned first base circle, and the normals of the first base circle and the second base circle are assumed to be the base axis. Since the gear 213 groove has a limiting effect on the gear 213, the gear 213 can only rotate relative to the second connecting member 212 but cannot be displaced relative to the second connecting member 212. When the gear 213 rolls along the dial 211b, the gear 213 will rotate while moving along the circumferential direction of the second base circle. Under the limiting effect of the gear 213 groove, the second connecting member 212 will move along the second base circle with the gear 213. Since the first base circle is coaxially arranged with the second base circle, finally the second connecting member 212 will also rotate around the base axis under the action of the first slide groove 212a and the limiting column 211a, thereby driving the second frame 12 to rotate relative to the first frame 11.

[0044] In this embodiment, the connecting shaft 22 is in transmission connection with the gear 213. The rotation of the connecting shaft 22 can drive the gear 213 to rotate. Under the action of the sawtooth, the gear 213 rolls along the scale plate 211b. Under the joint action of the gear 213 and the limiting column 211a, the second connecting member 212 rotates around the base axis relative to the first connecting member 211, thereby driving the second frame 12 to rotate relatively. Among them, the motion track of the limiting column 211a in the first slide groove 212a, the motion track of the gear 213, and the motion track of the second frame 12 rotating relative to the first frame 11 can all be regarded as rotations around the same base axis.

[0045] In one embodiment, the connecting mechanism 2 further includes a locking assembly 23, which has a locked state and an unlocked state. When the locking assembly 23 is in the locked state, the locking assembly 23 can limit the relative rotation of the first connecting member 211 and the second connecting member 212; the locking assembly 23 includes: a push-pull disk 231, a pivot 232, a first connecting rod 233 and a connecting rod 234; the push-pull disk 231 is used to switch the locked state and the unlocked state under the action of an external force; one end of the pivot 232 is fixedly connected to the second connecting member 212, and the other end is rotatably connected to the push-pull disk 231; the first connecting member 211 is provided with a second slide groove 211c for the pivot 232 to pass through, and the second slide groove 211c is arranged in an arc shape, and the pivot The shaft 232 can slide along the second slide groove 211c; the push-pull plate 231 is provided with a third slide groove 231a for the first connecting rod 233 to slide, one end of the first connecting rod 233 can be slidably set in the third slide groove 231a, and the other end is fixedly connected to the second connecting member 212; the two ends of the connecting rod 234 are respectively connected to the pivot 232 and the first connecting rod 233; the first connecting rod 233 has a locking position and an unlocking position in the third slide groove 231a, and when the first connecting rod 233 is in the locking position, the locking assembly 23 is in a locked state; the push-pull plate 231 can rotate around the pivot 232 under the action of external force to drive the first connecting rod 233 to slide in the third slide groove 231a to the locking position or the unlocking position.

[0046] In this embodiment, the push-pull disk 231 rotates around the pivot 232, and the second slide groove 211c is extended in an arc shape along the rotation direction of the push-pull disk 231. The full circle where the arc is located is set as a third base circle, and the third base circle coincides with the axis where the pivot 232 is located. That is, when the first connecting rod 233 slides in the third slide groove 231a, its sliding trajectory can actually be regarded as rotating around the pivot 232. Therefore, when the first connecting rod 233 slides from one end of the third slide groove 231a to the other end, under the action of the connecting rod 234, the second connecting member 212 connected to the first connecting rod 233 will be driven to rotate around the pivot 232, and the base axis of the third base circle is aligned with the base axis of the first base circle. The positions are different, so when the second connecting member 212 rotates around the pivot 232, which is the base axis of the third base circle, the base circle where the first slide groove 212a on the second connecting member 212 is located will deviate from the original position, while the limiting column 211a on the first connecting member 211 is still in the original first base circle, so that the extension direction of the first slide groove 212a and the rotation direction of the limiting column 211a are not on the same base circle, that is, the rotation trajectory of the limiting column 211a is not coaxial with the base circle where the first slide groove 212a is located. At this time, the rotation of the gear 213 can no longer drive the limiting column 211a to rotate in the first slide groove 212a, thereby realizing the interlocking of the first connecting member 211 and the second connecting member 212.

[0047] In this embodiment, the locking assembly 23 is used to lock the relative position of the first connecting member 211 and the second connecting member 212. When the second connecting member 212 has been adjusted to a preset position, that is, the second frame 12 has been adjusted to a preset angle relative to the first frame 11, the push-pull disk 231 is toggled, and the push-pull disk 231 rotates around the pivot 232 so that the locking assembly 23 is converted from an unlocked state to a locked state. At this time, the first connecting member 211 and the second connecting member 212 cannot rotate relative to each other, and the relative position of the first frame 11 and the second frame 12 is therefore fixed.

[0048] In one embodiment, the flexible LED display screen 100 further includes a handle, which can be rotatably mounted on the side of the support assembly 3 away from the LED display screen 4. The handle includes a lifting ring and a mounting member, one end of the mounting member is mounted on the support assembly 3 by a fastener, and the other end is provided with a fixed shaft, and the lifting ring is rotatably connected to the fixed shaft, so that the lifting ring can be rotated to a suitable position when in use for the convenience of the user to carry, and can be rotated and stored in a preset position when not in use to avoid affecting the installation of other components.
