Description

Technical Field

[0001] This invention relates to the field of splicing display technology, specifically a quick-release and easy-to-maintain LED display module and its locking assembly structure. Background Technology

[0002] With the rapid development of display technology, LED splicing displays have been widely used in many fields such as commercial advertising, stage rental, and command and control due to their significant advantages such as high brightness, seamless splicing, and long service life. At the same time, in order to meet the special visual immersion, especially to present a highly impactful naked-eye stereoscopic visual effect and spatial adaptation requirements, the application scenarios of splicing multiple curved LED display modules into tubular, columnar, and other irregularly shaped splicing displays are increasing. This irregular splicing based on the characteristics of curved surfaces and ring-shaped enclosure is a key form for constructing a high-quality naked-eye stereoscopic visual display carrier. This irregular splicing method puts forward higher requirements for the assembly structure and maintenance method of display modules.

[0003] However, in the assembly and maintenance of existing curved LED splicing displays, modules are mostly fastened with screws or magnetically. Screws require tools to tighten and loosen individually, which is time-consuming, labor-intensive, and inefficient. Magnetic fastening has poor positioning accuracy and is prone to detachment due to vibration, resulting in insufficient reliability. The interior of the tubular, irregularly shaped display is a narrow, enclosed space. When a module malfunctions, it is extremely difficult for maintenance personnel to reach inside with their hands and tools for single-point disassembly. They often have to remove surrounding intact modules sequentially, easily causing secondary damage, leading to splice misalignment or grating displacement, severely disrupting the continuity and accuracy of naked-eye stereoscopic imaging. Some snap-on quick-release structures are generally easy to lock but difficult to remove; once the module is inserted and locked, the connection is tight but lacks... An effective ejection separation mechanism requires forceful pulling outwards during unlocking, which can easily damage the module edges or internal wiring, leading to display distortion and affecting the viewing experience of naked-eye 3D vision. When multiple curved modules are spliced ​​together into a tubular shape, the splicing points are easily affected by gravity and tolerances, causing inward collapse or outward bulge deformation. Naked-eye 3D vision has extremely stringent requirements for the geometric curvature and surface accuracy of the screen. Even a slight collapse or bulge can cause 3D parallax image crosstalk or visual jumps. The existing internal support frame is difficult to balance high-strength radial support with clearance during disassembly. The support structure and locking layout are prone to interference, making it difficult to maintain the high flatness and structural stability of the tubular module, ultimately resulting in the deterioration of the naked-eye 3D vision display effect. Summary of the Invention

[0004] Technical problems to be solved The purpose of this invention is to overcome the shortcomings of existing splicing displays, such as cumbersome assembly and disassembly, low efficiency, difficulty in disassembly due to narrow internal space, easy jamming after locking, lack of pop-out mechanism, and easy deformation of arc splicing, which hinders the stability of support. Technical solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release and easy-maintain LED display module and its locking assembly structure, comprising: LED display blocks, which are arc-shaped and can be spliced ​​into tubular modules, and the tubular modules constitute a display carrier for naked-eye stereoscopic vision. The arc-shaped structure provides a precise optical surface basis for parallax imaging of naked-eye stereoscopic vision. The rear end of the LED display block is fixedly connected to two symmetrically arranged inserts, and the surface of the inserts is provided with limit holes as connectors for module splicing. Locking components are located inside the modules where LED display blocks are spliced, and inserts are inserted into the locking components for disassembling and installing LED display blocks. The skeleton assembly is located at the central axis of the LED display panel splicing module, serving as the internal support and connecting base of the module; The control component is fixedly connected to the outside of the frame component, and the working end of the control component (6) extends into the interior of the locking component, for controlling the quick disassembly and replacement of the LED display block by the locking component.

[0006] Furthermore, the locking assembly includes: A connecting frame, wherein the connecting frame is provided with several groups evenly distributed in a circular array; The locking box is fixedly connected to the inside of the connecting frame in a linear array, and the locking box has a locking cavity inside. The locking box has two symmetrically arranged insertion holes on the outside, and the insertion holes are connected to the inside of the locking cavity. A compression spring is fixedly connected inside the locking cavity, and the compression spring is located on the same horizontal plane as the insertion hole; The top block is fixedly connected to the other end of the compression spring and is used to eject the insert into the locking cavity after the locking is released.

[0007] Furthermore, the locking assembly also includes: A locking strip is symmetrically arranged inside the locking cavity. One end of the locking strip has a connecting hole, and the other end of the locking strip is hook-shaped to hook the limiting hole. A connecting shaft passes through the interior of a connecting hole and is rotatably connected to the connecting hole. Both ends of the connecting shaft are fixedly connected to the interior of a locking cavity.

[0008] Furthermore, the bottom end of the locking strip away from the connecting hole is raised, and a return spring is fixedly connected to the bottom of the raised position of the locking strip. This spring is used to insert the insert through the insertion hole into the inside of the locking cavity and press against the hook-shaped end of the locking strip, causing its tail to be raised and then reset, so that the hook-shaped end of the locking strip engages with the inside of the limiting hole to achieve the locking operation.

[0009] Furthermore, the skeleton component includes: The main rod has a base fixedly connected to its bottom, and the bottom of the connecting frame is fixedly connected to the surface of the base. The top of the main rod is threaded, and a top cover is movably connected to the top of the main rod via the thread. The fixing rings are arranged in a linear array and are uniformly fixed to the outside of the main rod. Each fixing ring corresponds to a module of LED display panel splicing. The outside of the fixing rings is fixedly connected to a number of support bars in a ring array. The other end of each support bar is fixedly connected to a stop bar, which is arc-shaped. The outside of the stop bar is close to the inside of the gap between the LED display panels.

[0010] Furthermore, the outer side of the fixing ring is fixedly connected with several guide seats in a ring array, and the guide seats are U-shaped, with the guide seats located on opposite sides of the two support bars.

[0011] Furthermore, the control component includes: A control block, located inside the locking cavity; A tension spring, which is located inside the locking cavity; One end of the tension spring is fixedly connected to one side of the control block, and the other end of the tension spring is fixedly connected to the inside of the locking cavity. The other side of the control block is in close contact with the two locking bars, and the other side of the control block is in close contact with the position where the locking bar is raised.

[0012] Furthermore, a pull rope is fixedly connected to one side of the control block, and the other end of the pull rope passes through the interior of the locking box and the guide seat in sequence and is fixedly connected to a pull ring.

[0013] Furthermore, each of the guide seats is fixedly connected to a guide wheel. The pull rope slides through the hub of the guide wheel at different heights, and the pull ring is locked at the top of the topmost guide seat.

[0014] Compared with existing technologies, this quick-release and easy-maintain LED display module and its locking assembly structure have the following advantages: I. This invention utilizes a locking assembly that, when the insert is inserted into the locking cavity, pushes the locking bar in conjunction with a reset spring to automatically engage and lock the hook-shaped end with the limiting hole. Simultaneously, the compression spring is compressed and stores force. Upon unlocking, the compression spring releases its elasticity, automatically ejecting the insert from the locking cavity through the top block. This achieves self-locking during LED display block insertion and instantaneous ejection during unlocking. Precise positioning and rapid removal of individual modules can be accomplished without the need for additional tools, ensuring a seamless and flush splicing state between modules. This avoids damage to the imaging accuracy and image continuity of naked-eye stereoscopic vision due to misalignment of the splicing seams, simplifies disassembly and assembly operations, and improves maintenance efficiency.

[0015] Second, this invention, through the design of a control component, utilizes the cooperation of a pull ring, a pull rope, and a guide wheel to transmit pulling force over a long distance to the control block inside the locking cavity. By pressing down on the tail of the locking strip by the control block, the hook-shaped end is forced to lift up and disengage from the limiting hole, thus realizing the linkage unlocking inside the tubular module. The operator only needs to pull the pull ring at the top to control the locking and unlocking of the corresponding module, without having to put their hands into the narrow tubular module to operate. This avoids squeezing displacement or secondary damage to surrounding modules during disassembly, thereby ensuring the overall optical consistency of the naked-eye stereoscopic vision display surface and further improving the convenience and safety of quick disassembly.

[0016] Third, this invention utilizes a frame assembly, including a main rod, fixing rings, support bars, and arc-shaped abutments, to construct a stable internal support frame. The arc-shaped abutments fit tightly against the inner side of the LED display panel, effectively ensuring the roundness and structural stability of the multiple arc-shaped modules after being spliced ​​into a tubular shape. This prevents dents or deformations at the splicing points, providing a precise and stable optical surface foundation for naked-eye stereoscopic vision. It eliminates 3D parallax crosstalk and visual jumps caused by surface distortion. At the same time, the threaded connection between the top cover and the main rod enables quick assembly and positioning of the frame, and the guide seat provides orderly guidance and support for the pull rope of the control component. This ensures that the overall device has high structural strength and operational reliability while possessing quick-release functionality, maintaining excellent naked-eye stereoscopic vision display effects for a long time.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-8 As shown, the present invention provides a technical solution: a quick-release and easy-maintain LED display module and its locking assembly structure, comprising: LED display block 1 is arc-shaped and can be spliced ​​into a tubular module. The tubular module constitutes a display carrier that presents naked-eye stereoscopic vision. The arc structure provides a precise optical surface basis for parallax imaging of naked-eye stereoscopic vision. Two symmetrically arranged inserts 2 are fixedly connected to the rear end of LED display block 1. Limiting holes 3 are opened on the surface of the inserts 2 as connectors for module splicing. Locking components 4 are located inside the modules where LED display blocks 1 are spliced, and inserts 2 are inserted into the locking components 4 for disassembling and installing LED display blocks 1. Skeleton component 5 is located at the central position of the module where LED display blocks 1 are spliced, serving as the internal support and connecting base of the module; Control component 6 is fixedly connected to the outside of frame component 5, and the working end of control component 6 extends into the interior of locking component 4, used to control the quick disassembly and replacement of LED display block 1 by locking component 4.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the locking assembly 4 includes a connecting frame 401, which has several sets of evenly distributed ring arrays to perfectly fit the circumferential splicing shape of the tubular module. Locking boxes 402 are linearly arrayed and fixedly connected to the interior of the connecting frame 401 to match the stacking and assembly requirements of the module. A locking cavity 403 is provided inside the locking box 402, and two symmetrically arranged insertion holes 404 are provided on the outer side of the locking box 402. The insertion holes 404 communicate with the interior of the locking cavity 403, providing a precise insertion guide channel for the insert 2. A compression spring 405 is also included. 405 is fixedly connected to the inside of the locking cavity 403, and the compression spring 405 is located on the same horizontal plane as the insertion hole 404. The top block 406 is fixedly connected to the other end of the compression spring 405. It is used to pop the insertion strip 2 out of the locking cavity 403 after the locking is released. During the insertion of the insertion strip 2, the top block 406 is compressed and the compression spring 405 contracts to store force. When the locking is released, the compression spring 405 releases potential energy instantly and actively pops the insertion strip 2 outward through the top block 406, which completely avoids the problem of the insertion strip 2 getting stuck and difficult to pull out, and realizes a smooth disassembly experience of unlocking and disassembling.

[0023] The locking assembly 4 also includes a locking strip 407, which is symmetrically arranged inside the locking cavity 403. It is a lever force structure with the connecting shaft 409 as the fulcrum. One end of the locking strip 407 has a connecting hole 408, and the other end of the locking strip 407 is hook-shaped to hook the limiting hole 3. This ensures that the insert 2 is evenly stressed on both sides when locked, effectively preventing the LED display block 1 from falling off due to unilateral tilting, shaking, or uneven stress. This ensures the flatness and structural stability of the module after splicing. The connecting shaft 409 passes through the inside of the connecting hole 408 and is rotatably connected to the connecting hole 408. Both ends of the connecting shaft 409 are fixedly connected to the inside of the locking cavity 403.

[0024] The bottom end of the locking strip 407, away from the connecting hole 408, is raised. A return spring 410 is fixedly connected to the bottom of the raised position of the locking strip 407. When the insert 2 is inserted into the locking cavity 403 through the insertion hole 404, it presses against the hook end of the locking strip 407, causing its tail to be raised and press down on the return spring 410 to store force. When the limit hole 3 reaches the position of the hook end and the thrust disappears, it resets. Thus, the hook end of the locking strip 407 quickly engages with the inside of the limit hole 3 under the elastic drive of the return spring 410 to achieve the locking operation. This realizes automatic locking that is self-locking upon insertion, without the need for manual tightening or operation, thus improving the assembly efficiency and reliability of large-area tubular LED displays.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the skeleton assembly 5 includes a main rod 501, and a placement seat 502 is fixedly connected to the bottom of the main rod 501. As the core load-bearing shaft of the entire tubular module, the placement seat 502 provides a stable bottom base support to ensure the stability of the overall device when placed vertically. The bottom of the connecting frame 401 is fixedly connected to the surface of the placement seat 502. The top of the main rod 501 is threaded, and the bottom axis of the top cover 7 is movably connected to the top of the main rod 501 through the thread. The threaded engagement realizes the quick sealing and axial limitation of the top of the skeleton assembly 5, preventing the splicing structure of each layer from shifting upwards, and at the same time, it is easy to unscrew and disassemble for internal inspection and maintenance.

[0026] Several fixing rings 504 are arranged in a linear array and uniformly fixed to the outside of the main rod 501. Together with the main rod 501, they form a sturdy multi-layer frame base. Each fixing ring 504 corresponds to a module spliced ​​by each layer of LED display blocks 1. Several support bars 505 are fixedly connected to the outside of the fixing rings 504 in a ring array. The other end of each support bar 505 is fixedly connected to a stop bar 506. The stop bar 506 is arc-shaped, and its outer side is close to the inner side of the gap between the LED display blocks 1. The arc-shaped design perfectly fits the inner wall of the LED display block 1, providing uniform outward radial support force. This effectively prevents the tubular module from collapsing or deforming inward after splicing. This is the key to maintaining the optical curvature accuracy of naked-eye stereoscopic vision, avoiding 3D image distortion and visual jump caused by surface distortion, and ensuring the roundness and structural stability after large-area splicing.

[0027] The outer side of the fixed ring 504 is fixedly connected with several guide seats 503 in a ring array, and the guide seats 503 are U-shaped. The guide seats 503 are located on opposite sides of the two support bars 505. The U-shaped structure provides precise limit and steering support for the pull rope 603 of the subsequent control component 6. The reasonable spatial layout not only avoids motion interference between the pull rope 603 and the support bar 505 or the LED display block 1, but also ensures smooth guidance and regular path when the pull rope 603 is pulled.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the control component 6 includes a control block 601 located inside the locking cavity 403, serving as a transmission component that directly performs the unlocking action. A tension spring 602 is located inside the locking cavity 403, with one end of the tension spring 602 fixedly connected to one side of the control block 601 and the other end fixedly connected to the inside of the locking cavity 403, providing the control block 601 with a normal reset force. The other side of the control block 601 is in close contact with the two, and the other side of the control block 601 is in close contact with the raised position of the locking bar 407. When the control block 601 is driven, it overcomes the tension of the tension spring 602 and moves towards the raised end of the locking bar 407 and presses down, forcing the locking bar 407 to rotate around the connecting shaft 409, thereby causing its hook-shaped end to disengage from the limiting hole 3, instantly releasing the locking state. After the external force is released, the tension spring 602 retracts and resets, pulling the control block 601 away from the raised position, preparing for the next automatic locking.

[0029] A pull rope 603 is fixedly connected to one side of the control block 601, and the other end of the pull rope 603 passes through the interior of the locking box 402 and the guide seat 503 and is fixedly connected to a pull ring 604. This converts the mechanical action inside the internal locking cavity 403 into an external long-distance traction operation. The operator does not need to put their hands into the narrow tubular module. They only need to pull the pull ring 604 from the outside of the device to accurately transmit the pulling force to the deep control block 601 through the pull rope 603. This improves the convenience and safety of quick disassembly operations and is especially suitable for disassembly and assembly scenarios where the internal space is limited after multiple modules are assembled.

[0030] Guide wheels 605 are fixedly connected inside the guide seat 503. Pull ropes 603 of different heights slide through the hubs of the corresponding guide wheels 605. The guide wheels 605 not only convert the sliding friction of the pull ropes 603 into rolling friction, significantly reducing pulling resistance and rope wear, but also smoothly convert the radial tension of the pull ropes 603 into axial pulling force through the limiting guide of the hub, ensuring that the pull ropes 603 move smoothly and do not deviate or derail. The pull rings 604 are locked at the top of the top guide seat 503, so that the pull rings 604 of different levels eventually converge in the top area. The operator can easily reach and operate the unlocking pull rings 604 of any height module from the same external position, realizing centralized and efficient maintenance management.

[0031] Working principle: When it is necessary to install the curved LED display block 1, the insert 2 fixedly connected to its rear end is aligned with the insertion hole 404 opened on the outside of the locking box 402 and inserted. After the insert 2 enters the locking cavity 403 inside the locking box 402, its end first contacts the hook end of the locking bar 407 and pushes the locking bar 407 to rotate around the connecting shaft 409 that passes through its connecting hole 408. At this time, the tail of the locking bar 407 away from the connecting hole 408 tilts downward and compresses the return spring 410 fixedly connected to its bottom. At the same time, the insert 2 pushes the top block 406 fixedly connected to one end of the compression spring 405 inward, so that the compression spring 405 is compressed. When the insert 2 is fully inserted into the limiting hole 3 on its surface and reaches the hook end of the locking strip 407, the pushing force of the insert 2 on the hook end of the locking strip 407 disappears. The return spring 410 releases its elastic force to push the tail of the locking strip 407 back to its original position, causing the locking strip 407 to rotate in the opposite direction around the connecting shaft 409. Its hook end then inserts downward into the limiting hole 3 of the insert 2 to achieve automatic locking. At this time, multiple LED display blocks 1 are spliced ​​into a tubular module, and the inner side is tightly attached to the outer side of the arc-shaped abutment 506 of the frame assembly 5. 1. The support of the fixing ring 504 and the support bar 505 maintains the roundness and stability of the tubular module, ensuring the strict optical curvature and seamless splicing required for the naked-eye stereoscopic vision display carrier, so that the audience can enjoy a highly immersive naked-eye 3D stereoscopic image without wearing auxiliary equipment. At the same time, the placement seat 502 at the bottom of the main rod 501 provides stable support for the connecting frame 401 and locking box 402 distributed in a ring array. The top cover 7 at the top of the main rod 501 completes the limiting assembly of the overall skeleton through threaded connection. When it is necessary to quickly disassemble and maintain a certain LED display block 1 in the tubular module, the operator pulls the pull ring 604 that is locked at the top guide seat 503. The pull ring 604 drives the fixedly connected pull rope 603 to move. The pull rope 603 slides along the guide wheel 605 fixedly connected inside the guide seat 503 at the corresponding height, and transmits the pulling force to the control block 601 inside the locking cavity 403. After the control block 601 is pulled, it moves towards the raised position of the locking bar 407 and presses down against the tension of the tension spring 602, forcing the locking bar 407 to rotate around the connecting shaft 409. This overcomes the elasticity of the return spring 410, causing the hook end to disengage from the limiting hole 3 of the insert 2 and release the locking state. During this pulling process, the tension spring 602, which is fixedly connected between the control block 601 and the inner wall of the locking cavity 403, is stretched and stores force. After the locking is released, the compressed compression spring 405 releases its elasticity, and the insert 2 is ejected outward from the locking cavity 403 through the top block 406, so that the LED display block 1 can be quickly removed. After the pull ring 604 is released, the tension spring 602 retracts and resets, pulling the control block 601 away from the raised position of the locking bar 407. The locking bar 407 returns to its initial state under the action of the reset spring 410, preparing for the next locking assembly. This realizes the quick disassembly and easy maintenance of the LED display block 1, and also improves the operation and maintenance efficiency and operational stability of the naked-eye stereoscopic vision display system.
