Description

Technical Field

[0001] This invention belongs to the field of LED display technology, specifically a self-adaptive rotatable multi-angle LED module with an F-shaped single-point locking structure. Background Technology

[0002] With the rapid development of LED displays, the demand for various irregularly shaped creative displays is becoming increasingly strong. To meet the needs of creative irregularly shaped screens, LED modules need to be able to adaptively rotate at multiple angles to conform to the curves of the irregular shape. They also need to be quick to install and maintain, while possessing a certain degree of robustness to withstand external forces. Furthermore, the number of LED module types should be minimized to reduce the design and manufacturing costs of the screen.

[0003] LED Module Rotation Splicing Angle: Currently, the industry still relies on customized angles for rotating LED modules in outdoor or indoor creative displays. Angles need to be designed in advance, molded, or machined to create various customized splicing angles for the project. This method is time-consuming, labor-intensive, and expensive. Furthermore, if there are dimensional or angle deviations at the installation site, the customized angles will be unusable, requiring temporary processing and correction. This can significantly delay the delivery time of such creative, irregularly shaped display projects.

[0004] LED Module Installation and Maintenance: Currently, the industry's methods for installing and maintaining LED modules for outdoor or indoor creative displays are basically still limited to magnetic or screw-type fixing.

[0005] However, the magnetic fixing splicing method can cause the modules to loosen or fall off when subjected to external forces, including natural forces such as wind, rain, and snow, which can affect the display effect or even safety.

[0006] Using screws for fixing requires a high-precision machined enclosure structure, resulting in numerous non-standard enclosure designs and a significant amount of screw installation work. The design, manufacturing, and construction costs are substantial.

[0007] Therefore, we need an LED module that, when used with a corresponding keel, can easily achieve splicing at multiple angles. Summary of the Invention

[0026] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0027] Reference Figures 1-9This embodiment provides an adaptive rotatable multi-angle LED module with an F-shaped single-point locking structure, including: a display component 100, which includes a mask 101, a lamp plate 102, and a housing 103, with the lamp plate 102 disposed on one side of the housing 103 and the mask covering the lamp plate 102; a rotation component 200, which includes a fixing plate 201 and an arc plate 202, with an arc-shaped countersunk hole 203 on the arc plate 202; a fixing groove 103a at one end of the housing 103, with the fixing plate 201 disposed in the fixing groove 103a; and an arc groove 103b at the other end of the housing 103, with a locking bolt 103c disposed in the arc groove 103b; and a fixing component 300 and a fixing frame 400, with the display component 100 mounted on the fixing frame 400 via the fixing component 300.

[0028] Specifically, a positioning shaft and a threaded hole are provided at the diagonal of the fixing groove 103a, and multiple through holes are provided on the fixing plate 201. The positioning shaft is set in the through hole, and the bolt also passes through the through hole and is fixed in the threaded hole. The LED modules are electrically connected by a waterproof combination cable.

[0029] In this embodiment, the combination of display component 100, rotating component 200 and fixing component 300 forms a single LED module, which is tightly installed on the fixing frame 400 to form an overall display system. Each pair of single LED modules is connected by rotating component 200. Locking bolt 103c is connected to arc plate 202 on adjacent housing. Locking bolt 103c is set in arc-shaped countersunk hole 203. By adjusting the position of locking bolt 103c in arc-shaped countersunk hole 203 and tightening locking bolt 103c, the angle between two adjacent single LED modules can be adjusted. In this embodiment, the inner and outer curvature can be adjusted by ±8 degrees, and the dot pitch between modules is guaranteed, without producing "black line" phenomenon. It can adapt to the installation of various irregular screen shapes.

[0030] Specifically, the manufacturing process of the overall display system is as follows: Through laser processing, irregularly shaped single-curved surface fixing frame 400 (keel) can be easily made, and a locking opening 401 is cut on the fixing frame 400, which makes production simple and convenient; then, according to the shape of the fixing frame 400, the splicing angle between individual LED modules is adjusted, and they are assembled and fixed with the fixing frame 400 without the need for pre-customization.

[0031] Furthermore, the center of the arc groove 103b is located at the first side edge 103d of the lamp panel 102, and the center of the arc plate 202 is located at the second side edge 103e of the lamp panel 102.

[0032] Therefore, when the two display components 100 are spliced ​​together, the arc plate 202 is embedded in the arc groove 103b. The first side edge 103d of the first lamp plate 102 is in contact with the second side edge 103e of the next lamp plate 102. When the two lamp plates 102 are rotated to adjust the angle, that is, when the arc plate 202 moves in the arc groove 103b, the first side edge 103d and the second side edge 103e are still in contact and approximately coincident, maintaining a tight connection and avoiding the generation of "black lines".

[0033] Furthermore, the fixing component 300 includes a vertical plate 301, a first horizontal plate 302 and a second horizontal plate 303. The vertical plate 301 is fixed to the other side of the housing 103. The vertical plate 301 is provided with a mounting hole 301a, and the first horizontal plate 302 is provided with a first maintenance hole 302a.

[0034] The vertical plate 301 is fixed to the housing 103 by bolts.

[0035] The second horizontal plate 303 can be bent downwards to avoid the component between the first horizontal plate 302 and the second horizontal plate 303.

[0036] Below the first horizontal plate 302, there is a first limiting plate 302b and a second limiting plate 302c. The first limiting plate 302b has a through hole 302d, and the second limiting plate 302c has a second maintenance hole 302e.

[0037] Reference Figure 2 To further facilitate installation and maintenance, the first maintenance hole 302a and the second maintenance hole 302e can be connected.

[0038] The first limiting plate 302b and the second limiting plate 302c are disposed between the first horizontal plate 302 and the second horizontal plate 303, and are perpendicular to the first horizontal plate 302.

[0039] The adjusting screw 304 is located between the first horizontal plate 302 and the second horizontal plate 303 of the locking block 305.

[0040] Specifically, refer to Figure 7 The fixing frame 400 is embedded between the first horizontal plate 302 and the second horizontal plate 303. The side of the fixing frame 400 abuts against one side of the vertical plate 301. The first limiting plate 302b and the second limiting plate 302c contact the fixing frame 400 to form two limiting points, which together with the contact surface of the second horizontal plate 303 and the fixing frame 400 form a limiting point to prevent a single LED module from rotating relative to the fixing frame 400.

[0041] The fixing component 300 also includes an adjusting screw 304, which is inserted into the through hole 302d. The adjusting screw 304 has an end head 304a at its end and an end groove 304b on its side. A fixing tube 103f is provided in the housing 103, and the end 304a is provided in the fixing tube 103f.

[0042] The end slot 304b can be an internal hexagonal slot. Specifically, a baffle is also provided in the fixing tube 103f to prevent the end 304c from leaving the fixing tube 304a. However, the baffle is provided with a round hole to allow the adjustment screw 304 to rotate freely.

[0043] The adjusting screw 304 is provided with a first thread 304c and a second thread 304d.

[0044] A locking block 305 is provided on the adjusting screw 304. The locking block 305 is screwed into the first thread 304c. A spring 305a is provided on one side of the locking block 305 and connected to the housing 103.

[0045] A hook 305b is provided below the locking block 305, and an arc surface 305c is provided on the locking block 305.

[0046] It should be noted that the locking block 305 has a square structure, and the arc surface 305c is located at a ridge line on the side of the locking block 305, and the center line of the arc surface 305c coincides with the axis of the adjusting screw 304.

[0047] A nut is provided on the second thread 304d, which is located between the first limiting plate 302b and the second limiting plate 302c. The nut fixes the adjusting screw 304 to the first limiting plate 302b.

[0048] The mounting bracket 400 is provided with a locking opening 401.

[0049] The lamp panel 102 is provided with a reserved hole 102a, which corresponds to the end 304a.

[0050] Specifically, refer to Figure 8 The installation process of a single LED module onto the mounting bracket 400 in this invention is as follows: In the initial state, the hook 305b of the locking block 305 is in a horizontal state, and the hook 305b is between the vertical plate 301 and the first limiting plate 302b. The second thread 304d of the adjusting screw 304 is initially fixed by the nut.

[0051] Insert the fixing bracket 400 between the second limiting plate 302c and the second horizontal plate 303. The locking block 305 corresponds to the position of the latch opening 401. At this time, insert an Allen wrench into the end slot 304b from the reserved hole 102a and rotate clockwise. At this time, due to the arc surface 305c, the locking block 305 can rotate together with the adjusting screw 304. After rotating 90°, the top surface of the locking block 305 reaches the anti-rotation position with the first horizontal plate 302. At this time, since the locking block 305 cannot rotate, the locking block 305 will move laterally on the adjusting screw 304. The locking block 305 moves closer to the vertical plate 301 and the hook 305b is locked on the fixing bracket 400, pressing and fixing the side of the fixing bracket 400 with the vertical plate 301. The spring 305a is compressed and generates tension to form a self-locking effect on the locking block 305.

[0052] During disassembly, turn the adjusting screw 304 counterclockwise. Since the hook 305b is stuck on the fixing frame 400, the locking block 305 cannot rotate and can only move horizontally away from the vertical plate 301. When the hook 305b is no longer stuck on the fixing frame 400, the locking block 305 can rotate, thus completing the unlocking.

[0053] The LED module of this invention can adapt to various splicing angles without the need for pre-customized angles. Its economic value lies in its mass production capability, eliminating the high costs and time required for custom non-standard angle molds. Furthermore, it is not affected by discrepancies between the actual dimensions or angles of the project and the drawings, which could result in angle mismatches requiring subsequent time and expense for repairs.

[0054] The LED module's fixing component 300 forms a corner F-shaped stable shape combined with a single-point locking structure. The product shape of the fixing bracket 400, in conjunction with the laser-cut keel, allows for very simple installation of various screen shapes. The overall structure is simple and installation is easy; simply insert the fixing component 300 into the keel through the guide opening, and then use a standard Allen wrench to turn a screw at the front for stable fixing.

[0055] Single-point locking structure: Through the designed adjustment screw 304, combined with the ingenious locking hook design, the locking hook's movement direction is changed using the anti-rotation principle, easily achieving the locking action; then, a spring is used to generate self-locking of the locking hook. During maintenance, the rear bevel of the locking hook is used to restore its rotational movement, thereby restoring the hook body to a horizontal state, allowing the module to be removed from the keel using conventional methods such as suction cup tools and front removal handles.

[0056] Therefore, this invention, when used with a corresponding keel, can easily achieve splicing at multiple angles, and can be installed and maintained very simply, meeting all installation requirements for indoor and outdoor irregular-shaped screens, without generating huge design work, production and processing difficulties and costs.

[0057] Furthermore, when used outdoors, adhesive needs to be applied to the front and back of the printed circuit board to form protection. Since the overall weight of the product increases after adhesive application, the original 300-strength fixing components may not be able to withstand the load. Therefore, a stronger fixing component structure can be replaced to adapt to outdoor applications.

[0058] Reference Figure 9 When a single LED module is subjected to force at point A at the bottom, in the normal configuration, a torque will be generated at point B, with a lever arm length of L1 between A and B. Therefore, according to the torque formula M=rxF, the longer L1 is, the greater the force at point B will be. In this case, it will be difficult and unstable to fix the LED module at point B. Therefore, by using profile F, the force is converted to two points C and D. First, the direction of the force becomes a common horizontal direction, no longer the original vertical long lever arm direction. Second, the F profile is designed to have two force points (C and D), and the lever arm length L2 between C and D is very short. Assuming that in the normal configuration, point B is fixed, L1=10. When F1=100, fixing point B will be damaged, and the torque at this time is 10*100=1000.

[0059] If we transfer the force to point C or D through the F-shaped profile, then L2=2. Therefore, the force at point D that would be damaged would be F2=1000 / 2=500, and F2 / F1=5. Thus, changing to an F-shaped profile allows for greater stability under five times the force.

[0060] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
