Description

Technical Field

[0001] The present invention relates to the field of LED display screens, and in particular to an angle-adjustable LED display screen splicing support mechanism. Background Art

[0002] LED displays, as a visual display device widely used in advertising, stage performances, information releases, and other occasions, are usually composed of multiple LED display modules spliced ​​together to achieve continuous display of large-scale images. Existing LED splicing display systems mostly use a fixed splicing structure, that is, each module is connected edge to edge in a strict linear manner and the entire system is installed and positioned using fixed brackets. This type of splicing structure has certain advantages in ensuring the integrity of the image and overall aesthetics, but it also has the following defects and shortcomings: Existing splicing structures lack modular independent adjustment capabilities. In actual use, users may personalize the angles of some display modules based on different viewing angles, on-site layouts, or visual needs. For example, in certain surround arrangements, three-dimensional exhibition stands, or columnar splicing structures, if the display direction of each module cannot be flexibly adjusted, it will directly affect the viewing effect and visual impact. However, in the existing technology, the modules are usually tightly spliced ​​in a rigid manner, and the spacing between adjacent modules is extremely small, resulting in the inability of a single display module to independently adjust its angle. There is a lack of angle adjustment space, and the adjustment process is prone to jamming and structural interference.

[0003] As the application scenarios of LED displays continue to expand, some applications are no longer satisfied with a unified display across the entire screen. Instead, they desire to divide the entire screen into multiple independently controlled display units to meet diverse and customized display needs. For example, in exhibitions, different modules can play introductory videos and interactive content respectively. In stage performances, screen modules can project content in different directions based on the set structure. In retail advertising terminals, module angle adjustment can enhance the visual sense of three-dimensionality. These application requirements urgently require display splicing structures to have module-level angle adjustment capabilities and independent display adaptability. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an angle-adjustable LED display screen splicing support mechanism, which can not only realize independent angle adjustment of modules, but also widen the distance between adjacent modules during the adjustment process and ensure the splicing support structure with adjustment accuracy and operational convenience.

[0005] The present invention is realized by the following technical solution: an angle-adjustable LED display screen splicing support mechanism, comprising: A screen composed of multiple display screen modules; An angle adjustment displacement mechanism, one end of which is fixedly connected to the back of each display screen module; a back plate fixedly connected to the other end of each angle adjustment displacement mechanism; The fixed cylinders are respectively arranged at the upper and lower ends of the back plate. The back plate is fixedly connected to the fixed cylinders. Operating mechanisms are respectively installed on both sides of the fixed cylinders. The angle adjustment displacement mechanism is controlled by the operating mechanisms so that the angle values ​​of adjacent display screen modules are adjusted after they move away from each other.

[0006] As a preferred technical solution, each angle adjustment displacement mechanism forms an inclined angle less than 90 degrees with the horizontal plane, so that adjacent display screen modules can move away from each other during displacement.

[0007] As a preferred technical solution, each angle adjustment displacement mechanism includes an L-shaped base, which is fixedly mounted on the back plate in an inclined shape, and the L-shaped base includes a first main body and a second main body, and the first main body and the second main body are arranged in an L shape; The first main body is fixedly mounted on the back plate. A sliding groove is provided on the first main body. A first driving block is disposed in the sliding groove. A first spring is also disposed in the sliding groove. The first driving block is elastically pushed out by the first spring. A connecting rod is vertically mounted on the first driving block, and a Vientiane elastic connector is also mounted on the connecting rod. The connecting rod is connected to each display screen module through the Vientiane elastic connector. When the first driving block is displaced, the corresponding display screen module is displaced. It also includes a second driving block, which is arranged relative to the first driving block, and an inclined extrusion structure is provided between the first driving block and the second driving block. The second driving block is installed on an angle adjustment plate, and a driving rod is provided on the side of the angle adjustment plate away from the second driving block. The driving rod is elastically installed in the second main body, and one end of the driving rod installed in the second main body is linked to the operating mechanism.

[0008] As a preferred technical solution, a bending plate is provided on one side of the angle adjustment plate away from the angle adjustment plate, and a driving ball is provided on the side of the bending plate facing the display screen module. When the driving rod is fully inserted into the second main body, the driving ball does not contact the back of the display screen module.

[0009] As a preferred technical solution, the angle adjustment plate is provided with an avoidance groove at a position corresponding to the connecting rod, and the connecting rod and the universal elastic connector both pass through the avoidance groove and can be displaced left and right in the avoidance groove.

[0010] As a preferred technical solution, the inclined extrusion structure includes a first inclined extrusion surface arranged on the first driving block, and a second inclined extrusion surface arranged on the second driving block. The first inclined extrusion surface is in contact with the second inclined extrusion surface. When the second driving block squeezes the first driving block, the first spring is elastically compressed.

[0011] As a preferred technical solution, a movable guide block is fixedly installed on the driving rod, and the second main body portion is located on one side of the angle adjustment plate and is necked to form a necking limit surface. A plurality of second springs are arranged between the movable guide block and the necking limit surface of the second main body portion, one end of the second spring is fixedly connected to the necking limit surface, and the other end of the second spring is connected to the movable guide block. When the driving rod is fully inserted into the second main body portion, each second spring is in an elastically stretched state.

[0012] As a preferred technical solution, the operating mechanism includes a hollow operating handle, which is inserted into the operating channel of the fixed cylinder. The end surface of the operating handle is fixedly connected to a first pulling wire, which is fixedly connected to the driving rod. The driving rod passes through the back plate and communicates with the operating channel in the fixed cylinder. A pulling plate is further provided on one side of the inner wall of the second main body, and the pulling plate is slidably mounted in a pulling groove provided on the inner wall of the second main body. A driving track is provided on the outer circumferential surface of the driving rod, and a driving slider is provided on the side of the pulling plate facing the driving track. The driving slider is buckled into the driving track.

The third spring is used to reset the pulling plate. A threaded operating rod is installed in the internal thread of the operating handle, and a drive connector is provided at one end of the threaded operating rod extending into the operating channel. A second pulling wire is connected between the drive connecting head and the pulling plate. A guide roller is also provided in the operating channel, and the first pulling wire and the second pulling wire are guided and supported on the corresponding guide rollers.

[0013] As a preferred technical solution, the drive track includes a straight segment and a spiral segment. When the drive rod is fully inserted into the second main body, the drive slider is located in the straight segment. When the second spring elastically resets, the drive rod partially extends to the outside of the second main body. At this time, the drive slider is displaced to the starting end of the spiral segment. By rotating the threaded operating rod, the threaded operating rod moves outward relative to the operating handle to pull the second pulling wire, thereby causing the drive rod to perform circular rotation.

[0014] As an optimal technical solution, a limit plate is provided on the outside of the back plate at the position corresponding to the operating handle, and a locking screw is provided through the threaded hole on the limit plate to lock the axial position of the operating handle in the operating channel through the locking screw.

[0015] The beneficial effects of the present invention are as follows: by providing an angle adjustment displacement mechanism, the present invention enables each display screen module to be independently adjusted in angle without disassembly or affecting other modules, thereby meeting the needs of multiple scenes, special-shaped structures and personalized displays, and improving the adaptability and flexibility of the entire screen; By controlling the angle adjustment displacement mechanism through the operating handle, the target display module and the adjacent modules can be displaced relative to each other, thereby creating sufficient adjustment space, avoiding the mutual interference common in traditional tightly spliced ​​structures, and significantly improving the smoothness and operability of angle adjustment.

[0018] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides an angle-adjustable LED display screen splicing support mechanism, comprising a screen body composed of four display screen modules 1, two on each side. During normal use, the display screen modules 1 are seamlessly spliced ​​together. It also includes an angle adjustment displacement mechanism 9, one end of which is fixedly connected to the back of each display screen module 1; In order to achieve the support and installation of each display screen module 1, a back plate 2 is also included, which is fixedly connected to the other end of each angle adjustment displacement mechanism 9; For ease of operation, two fixed cylinders 3 are further included, which are respectively arranged at the upper and lower ends of the back panel 2. The back panel 2 is fixedly connected to the fixed cylinder 3. Operating mechanisms are respectively installed on both sides of the fixed cylinder 3. The angle adjustment displacement mechanism 9 is controlled by the operating mechanism so that the angle values ​​of adjacent display screen modules 1 can be adjusted after they move away from each other. When a certain display screen module 1 needs to be adjusted, it is only necessary to operate the operating mechanism at the corresponding position to adjust the angle value of the display screen module 1 at the corresponding position.

[0021] like Figure 3As shown, each angle adjustment displacement mechanism 9 forms an angle of less than 90 degrees with the horizontal plane, allowing adjacent display screen modules 1 to move away from each other during displacement. In this embodiment, the angle of inclination can be between 10 and 30 degrees, so that the corresponding display screen modules 1 can move away from each other in a diagonal manner after displacement, that is, the display screen modules 1 are displaced in both the width and length directions.

[0022] Among them, such as Figure 4 As shown, each angle adjustment displacement mechanism 9 includes an L-shaped base 95, which is fixedly mounted on the back plate 2 in an inclined shape. The L-shaped base 95 includes a first main body 952 and a second main body 951, and the first main body 952 and the second main body 951 are arranged in an L shape; The first main body 952 is fixedly mounted on the back plate 2. A sliding groove 94 is provided on the first main body 952. A first driving block 93 is provided in the sliding groove 94. A first spring 90 is also provided in the sliding groove 94. The first driving block 93 is elastically pushed out by the first spring 90. During normal splicing and use, each first spring 90 is in a compressed state. A connecting rod 96 is vertically mounted on the first driving block 93. A Vientiane elastic connector is also mounted on the connecting rod 96. The connecting rod 96 is connected to each display screen module 1 via the Vientiane elastic connector. When the first driving block 93 moves, the corresponding display screen module 1 moves. The Vientiane elastic connector allows the display screen module 1 to rotate relative to the connecting rod 96 and elastically recover its deformation. like Figure 4 As shown, the Vientiane elastic connector includes a first ball sleeve 97 and a second ball sleeve 98, one end of the first ball sleeve 97 is connected to the connecting rod 96, and one end of the second ball sleeve 98 is connected to the display module 1. A Vientiane connecting ball 99 is installed between the first ball sleeve 97 and the second ball sleeve 98 to achieve Vientiane connection. In order to achieve reset, multiple fourth springs 100 are also installed between the first ball sleeve 97 and the second ball sleeve 98, and elastic reset is achieved by multiple fourth springs 100.

[0023] It also includes a second driving block 91, which is arranged relative to the first driving block 93, and an inclined extrusion structure is provided between the first driving block 93 and the second driving block 91. The second driving block 91 is installed on an angle adjustment plate 102, and a driving rod 13 is provided on the side of the angle adjustment plate 102 away from the second driving block 91. The driving rod 13 is elastically installed in the second main body 951, and one end of the driving rod 13 installed in the second main body 951 is linked to the operating mechanism. When the second driving block 91 applies an extruding force to the first driving block 93, the first driving block 93 is squeezed, and then the first spring 90 is squeezed. At this time, the display screen modules 1 are set tightly together. Once the force applied by the second driving block 91 to the first driving block 93 is withdrawn, the first driving block 93 is pushed out by the first spring 90, and the first driving block 93 is tilted and displaced along the sliding groove 94. Since the connecting rod 96 connects the display screen and the first driving block 93, the corresponding display screen module 1 can also follow the tilt displacement, so that the display screen module 1 that needs to adjust the angle can open a certain gap with other display screen modules 1, and thus do not interfere when adjusting the angle.

[0024] like Figure 4 As shown, a bending plate 104 is provided on the side of the angle adjustment plate 102 away from the angle adjustment plate 102. A driving ball 103 is provided on the side of the bending plate 104 facing the display screen module 1. When the driving rod 13 is fully inserted into the second main body 951, the driving ball 103 does not contact the back of the display screen module 1. When the angle of the display screen module 1 needs to be adjusted, the driving rod 13 is ejected, and the angle adjustment plate 102 moves toward the back of the display screen module 1 until the driving ball 103 contacts the back of the display screen module 1. The driving ball 103 on the angle adjustment plate 102 rotates in a circle along the circumference of the display screen module 1. When the driving ball 103 reaches any position in the circumferential direction, the angle of the display screen module 1 is adjusted accordingly. Therefore, the angle of the display screen module 1 can be adjusted by simply rotating the angle adjustment plate 102 in a circle.

[0025] like Figure 4 As shown, an avoidance groove 101 is opened at the position of the angle adjustment plate 102 corresponding to the connecting rod 96. The connecting rod 96 and the universal elastic connecting member both pass through the avoidance groove 101 and can be displaced left and right in the avoidance groove 101 without affecting the displacement of the connecting rod 96.

[0026] Among them, the inclined extrusion structure includes a first inclined extrusion surface 92 arranged on the first driving block 93, and a second inclined extrusion surface arranged on the second driving block 91. The first inclined extrusion surface 92 is in contact with the second inclined extrusion surface. When the second driving block 91 squeezes the first driving block 93, the first spring 90 is elastically compressed.

[0027] like Figure 5 As shown, a movable guide block 15 is fixedly mounted on the driving rod 13, and the second main body 951 is located on one side of the angle adjustment plate 102 with an opening thereon for a constriction treatment to form a constriction limiting surface. A plurality of second springs 90 are arranged between the movable guide block 15 and the constriction limiting surface of the second main body 951, one end of the second spring 90 is fixedly connected to the constriction limiting surface, and the other end of the second spring 90 is connected to the movable guide block 15. When the driving rod 13 is fully inserted into the second main body 951, each second spring 90 is in an elastically stretched state. Once the pulling force on the driving rod 13 disappears, the elastic reset of the second spring 90 allows the driving rod 13 to be pushed out of the second main body 951, thereby driving the angle adjustment plate 102 to contact the back of the display screen module 1, so that the originally non-contact structure becomes in contact. At the same time, the second driving block 91 no longer presses the first driving block 93, and the display screen module 1 can achieve simultaneous displacement, that is, after the display screen module 1 moves away from other display screen modules 1, the angle adjustment capability of the angle adjustment plate 102 is triggered at the same time.

[0028] like Figure 5 As shown, the operating mechanism includes a hollow operating handle 4, which is inserted into the operating channel 14 of the fixed cylinder 3. The end surface of the operating handle 4 is fixedly connected to a first pulling wire 12, which is fixedly connected to the driving rod 13. The driving rod 13 passes through the back plate 2 and communicates with the operating channel 14 in the fixed cylinder 3. A pull plate 11 is also provided on one side of the inner wall of the second main body 951. The pull plate 11 is slidably mounted within a pull groove formed in the inner wall of the second main body 951. A drive track is provided on the outer circumference of the drive rod 13. A drive slider is provided on the side of the pull plate 11 facing the drive track. The drive slider is snapped into the drive track. A third spring is fixedly mounted in the pull groove. One end of the third spring is fixedly connected to the end surface of the pull plate 11. The third spring is used to reset the pull plate 11. When the display screen module 1 needs to be adjusted at the corresponding position, the operating handle 4 on the corresponding side is simply operated. The operating handle 4 only needs to be loosened, causing the previously tightened first pull wire 12 to relax. At this time, the previously tightened drive rod 13 is pushed out of the second main body 951 under the action of the second spring 90, causing the angle adjustment plate 102 to move toward and contact the back of the display screen module 1. When the angle of the display screen module 1 no longer needs to be adjusted, the operating handle 4 is pulled outward and positioned, allowing the drive rod 13 to retract into the second main body 951.

[0029] Please continue reading Figure 5The operating handle 4 is internally threaded with a threaded operating rod 6. The threaded operating rod 6 extends into the operating channel 14 and is provided with a drive connector 61 at one end. A second pulling wire 10 is connected between the drive connector 61 and the pulling plate 11. A guide roller 111 is also provided in the operating channel 14. The first pulling wire 12 and the second pulling wire 10 are guided and supported on the corresponding guide rollers 111. After loosening the first pulling wire 12, if you want to adjust the angle of the angle adjustment plate 102 in the circumferential direction, you only need to manually rotate the threaded operating rod 6. The operating handle 4 remains stationary, and the threaded operating rod 6 is rotated outward relative to the operating handle 4. In this way, the second pulling wire 10 is connected to the pulling plate 11 and pulls outward.

[0030] like Figure 6 As shown, the driving track includes a straight section 16 and a spiral section 17. When the driving rod 13 is fully inserted into the second main body 951, the driving slider is located in the straight section 16. When the second spring 90 is elastically reset, the driving rod 13 partially extends to the outside of the second main body 951. At this time, the driving slider is displaced to the starting end of the spiral section 17. By rotating the threaded operating rod 6, the threaded operating rod 6 moves outward relative to the operating handle 4 to pull the second pulling wire 10, thereby causing the driving rod 13 to rotate in a circular motion. After the driving rod 13 rotates in a circular motion, it will cause the angle adjustment plate 102 to rotate in a circular motion. Note that the rotation angle of the angle adjustment plate 102 here is limited, and the rotation angle value depends on the distance between the upper and lower ends of the avoidance groove 101. In this embodiment, the avoidance groove 101 is a closed groove. If the angle adjustment plate 102 obtains a larger rotation angle, the bottom of the avoidance groove 101 can be opened, so that the rotation angle of the angle adjustment plate 102 in the circumferential direction is larger and is not restricted by the avoidance groove 101. Figure 7 shown.

[0031] Among them, a limit plate 8 is provided on the outside of the back plate 2 at the position corresponding to the operating handle 4, and a locking screw 5 is provided through the threaded hole on the limit plate 8, and the axial position of the operating handle 4 in the operating channel 14 is locked by the locking screw 5. When the angle adjustment of the display screen module 1 is required, it is only necessary to loosen the locking screw 5, pull the operating handle 4 outward, and the first pulling wire 12 is relaxed. At this time, the threaded operating rod 6 is rotated to pull the second pulling wire 10, thereby driving the pulling plate 11 to move the driving slider in the driving track. When the first pulling wire 12 is relaxed, the driving slider moves in the straight section 16 until the threaded operating rod 6 is rotated. The driving slider will enter the spiral section 17. As the driving slider continues to be pulled, the driving rod 13 will be driven to rotate relative to the movable guide block 15 in a circular manner in the spiral section 17. Due to the rotation of the driving rod 13, the angle adjustment plate 102 and the second driving block 91 can be driven to rotate in a circular manner, and the driving ball 103 will rotate along the circumferential surface of the display screen module 1, thereby adjusting the angle of the display screen module 1; In order to realize the circumferential rotation of the driving rod 13 relative to the movable guide block 15 and ensure the synchronous movement of the driving rod 13 and the movable guide block 15 in the axial direction, as shown in FIG. Figure 8 As shown, the driving rod 13 is provided with a circular limiting portion 131 in the movable guide block 15, and a circular rotation groove is provided in the movable guide block 15 at a position corresponding to the circular limiting portion 131, so that the driving rod 13 can rotate in a circular manner relative to the movable guide block 15, but can also achieve axial synchronous movement in the axial direction.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
