Description

Technical Field

[0001] This utility model relates to the field of LED matrix modules, and in particular to an LED matrix module that is easy to quickly splice. Background Technology

[0002] LED large-screen displays have been widely used in public places such as advertising, information dissemination, and traffic signs due to their eye-catching features and flexible content. However, traditional LED displays are usually customized according to user requirements, requiring repeated design of circuits and mechanical structures each time. In fact, regardless of the size of the display, the principle is basically the same. Therefore, the design of standardized and modular LED displays has become a trend. Modular LED displays divide the entire display into several display modules of the same size and function. The operation of all display modules is synchronized by a central control module. The size can be flexibly changed as needed, and it can operate independently without a computer.

[0003] In existing technologies, traditional LED matrix modules mainly consist of an LED bead matrix, a PCB substrate, a driver chip, a metal base shell, and a mask, forming an independent display unit. The splicing connection components employ snap-fit ​​structures, bolt fasteners, and pluggable connectors, with some mechanically fixed via locking mechanisms in the module housing. Independent power interfaces, signal cables (HDMI / SDI, etc.), and cascaded signal transmission interfaces require additional wiring for power supply and signal synchronization. Furthermore, the standardized module frames and housing positioning pins rely on manual calibration for splicing alignment. However, in actual use, fixing this device relies on scattered components such as bolts and snap-fits, requiring individual alignment and manual tightening during splicing. This is particularly problematic in high-altitude operations (such as wall installation), where precise operation by a single person is difficult, time-consuming, and labor-intensive. Electrical connections require separate plugging and unplugging of power and signal cables, resulting in messy wiring and potential contact problems, increasing debugging time. Additionally, the reliance on manual calibration during installation can easily lead to module misalignment and angular displacement.

[0004] Therefore, it is necessary to propose an LED matrix module that is easy to quickly assemble to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an LED matrix module that is easy to assemble quickly, in order to solve the problems of traditional LED matrix module splicing relying on scattered parts, difficulty for single-person operation, messy wiring, and easy positioning deviation.

[0023] This utility model provides, for example Figures 1-5 The LED matrix module shown is designed to facilitate rapid assembly and solves the problems of traditional LED matrix module splicing, such as reliance on scattered components, difficulty for single-person operation, messy wiring, and easy positioning deviation. It achieves rapid splicing, convenient power supply and signal synchronization, and accurate positioning.

[0024] In this embodiment, the main body 1 of the LED matrix module is a rectangular independent display unit that integrates an LED matrix module, a PCB substrate, a driver chip, a metal base shell and a mask. The side away from the LED matrix module is the mounting surface. The four side walls are sequentially enclosed to form an outline. The first and second side walls are vertically connected along the first extension direction, and the third and fourth side walls are vertically connected along the second extension direction that intersects with the first extension direction.

[0025] Two symmetrically distributed connecting sleeves 9 are fixed near the first and second side walls of the mounting surface. Each connecting sleeve 9 has a first through groove on its opposite side. Rotating handles 10 are rotatably connected to the first and second side walls. Trapezoidal bidirectional screws 11 are fixedly connected to the inside of the rotating handles 10. Insert blocks 12 are threaded to both ends of the trapezoidal bidirectional screws 11. Insert blocks 12 are slidably fitted into the first through groove of the connecting sleeves 9. When the rotating handles 10 are rotated, they can drive the insert blocks 12 to move bidirectionally along the first through groove.

[0026] Two symmetrically distributed connecting blocks 4 are fixed near the third and fourth side walls of the mounting surface. Each connecting block 4 has a fixed connecting rod 6 on the side facing the corresponding side wall. The opposite side of the fixing rod 6 has a third through groove, and the cross-sectional size of the third through groove is completely matched with the insert block 12. The connecting sleeve 9 has a second through groove on the side facing the first and second side walls. The cross-sectional size of the second through groove is completely matched with the fixing rod 6 to ensure structural fit during splicing.

[0027] The socket end 7 is fixedly connected to the mounting surface near the first and second side walls. The socket end 7 is rotated to connect to the end cover 8 facing the corresponding side wall. The end cover 8 can close the socket end 7 to prevent dust and damage when not spliced. The side of the end cover 8 away from the rotation axis is provided with an elastic buckle. The socket end 7 is provided with a buckle groove at the corresponding position. When the end cover 8 is closed, the buckle is inserted into the buckle groove to achieve fixation. The plug end 5 is fixedly connected to the mounting surface near the third and fourth side walls. The number of plug ends 5 is completely matched with the socket end 7 and the end cover 8. The plug end 5 and the socket end 7 adopt a foolproof design to ensure the accuracy of electrical connection. One side of the plug end 5 is provided with a rectangular positioning boss. The corresponding position of the socket end 7 is provided with a matching positioning groove. The plug end 5 can only be inserted into the socket end 7 when the boss and the groove are aligned to achieve the foolproof function.

[0028] The first and second side walls are provided with mounting grooves 2, and the third and fourth side walls are fixedly connected with mounting strips 3. The mounting grooves 2 and the mounting strips 3 cooperate with each other to further improve the positioning accuracy during splicing and avoid module misalignment and angle shift.

[0029] During use, a single person carries the LED matrix module body 1 to the installation location, such as a wall mounting surface. First, fix the first module in the reference position, ensuring the mounting surface is flush with the wall. Determine the splicing direction according to the installation requirements: horizontal, vertical, or multi-dimensional splicing. Align the third and fourth sidewalls of the module to be spliced ​​with the first and second sidewalls of the fixed module, aligning the fixing rod 6 of the module to be spliced ​​with the second through groove of the connecting sleeve 9 of the fixed module. Simultaneously, align the insert 12 of the fixed module with the third through groove of the fixing rod 6 of the module to be spliced. Gently push to make the two initially fit together. The mounting strip 3 is embedded into the corresponding mounting groove 2 to achieve initial positioning. Manually rotate the rotating handle 10 on the fixed module to drive the trapezoidal bidirectional screw 11 to rotate. Through the threaded engagement, drive the inserts 12 at both ends to slide outward along the first through groove of the connecting sleeve 9 until the inserts 12 are fully inserted into the third through groove of the fixing rod 6 of the module to be spliced. Inside the slot, the mechanical fastening of the two modules is completed. The trapezoidal bidirectional screw 11, which is fixed inside the rotating handle 10 near the first side wall, is connected at both ends to the plugs 12 inside the two connecting sleeves 9 at the first side wall. The same applies to the rotating handle 10 near the second side wall. The whole process does not require additional tools and can be quickly operated by a single person. While mechanically splicing, the plug end 5 of the module to be spliced ​​is simultaneously inserted into the socket end 7 of the fixed module to achieve synchronous connection of power supply and signal. No separate wiring is required. If splicing is not required, the end cover 8 can be rotated to close the socket end 7 to prevent dust from entering or poor contact. Repeat the above steps to splice the subsequent modules in sequence. Through the positioning and cooperation of the mounting slot 2 and the mounting strip 3, and the fastening cooperation of the plug 12 and the third through slot, it is ensured that all modules are spliced ​​and aligned without misalignment or angular offset. At the same time, through cascaded electrical connection, the power supply and signal of all modules are synchronized.
