Detailed Implementation

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. Detachable connections can use screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Reference Figures 1-6 This utility model provides an LED display module 100, including a base shell 110, a PCBA board 120, a face mask 150, a fixing component, and a quick-installation component. The fixing component is used to connect the base shell 110 and the PCBA board 120, and the quick-installation component is used to connect the face mask 150 and the PCBA board 120, thereby realizing the installation of the base shell 110, the PCBA board 120, and the face mask 150 to form the LED display module 100.

[0026] Specifically, refer to Figure 4 The quick-install assembly includes a snap-fit ​​copper post 140. One end of the snap-fit ​​copper post 140 is fixedly connected to the PCBA board 120 by welding. The face mask 150 is provided with a mounting hole 151. The other end of the snap-fit ​​copper post 140 is engaged with the mounting hole 151, thereby realizing the detachable connection between the face mask 150 and the PCBA board 120, so as to facilitate quick installation and removal of the face mask 150 and facilitate the maintenance of the LED beads on the PCBA board 120.

[0027] Furthermore, refer to Figure 4 and Figure 6 The snap-fit ​​copper post 140 includes a main body 141 and a head 142. One end of the main body 141 is connected to the PCBA board 120, and the head 142 is connected to the other end of the main body 141. The diameter of the head 142 is larger than the diameter of the main body 141. The mounting hole 151 is a stepped hole and includes a connecting hole and a countersunk hole. The diameter of the main body 141 is smaller than the diameter of the connecting hole. The diameter of the head 142 is larger than the diameter of the connecting hole but smaller than the diameter of the countersunk hole. The head 142 has an elastic extension range to pass through the connecting hole. The side of the head 142 near the main body 141 is a flat surface, and the side of the head 142 away from the main body 141 is an arc surface.

[0028] It can be understood that, due to the elastic extension and retraction of the head 142, when installing the face mask 150, the head 142 retracts to pass through the connection hole. After passing through the connection hole, the head 142 returns to its natural state, limiting the bottom of the countersunk hole and preventing the face mask 150 from detaching from the PCBA board 120, thereby achieving quick installation of the face mask 150. When it is necessary to remove the face mask 150, simply apply force in the opposite direction to retract the head 142 and pass through the connection hole, and the face mask 150 can be quickly removed.

[0029] It can be understood that the diameter of the head 142 is slightly larger than the diameter of the connecting hole, so that the head 142 can both prevent the mask 150 from detaching and retract through the connecting hole, ensuring the smoothness of the mask 150 during disassembly and assembly and the stability after installation.

[0030] In a preferred embodiment, refer to Figure 2 The arc surface of the head 142 is provided with a black layer, which matches the black color of the mask 150 surface, improving the aesthetics of the LED display module 100 without affecting the LED image display effect.

[0031] In this embodiment, refer to Figure 3 , Figure 4 and Figure 6 The PCBA board 120 is provided with a welding hole 121, and the main body 141 is provided with a welding part 143. The diameter of the welding part 143 is larger than the diameter of the main body 141. The welding part 143 is closed-fitted into the welding hole 121 and welded to the side wall of the welding hole 121. This avoids the formation of weld seams on the surface of the PCBA board 120. The welding hole 121 also makes the snap-fit ​​copper pillar 140 more stable after welding, improves structural stability, avoids damage to the snap-fit ​​copper pillar 140 when installing the face shield 150, and improves service life.

[0032] In the preferred embodiment, refer to Figure 5 and Figure 6 The main body 141 is provided with a straight toothed cylinder 144, which is located between the welding part 143 and the head 142. When the face mask 150 is connected to the PCBA board 120, the straight toothed cylinder 144 is located between the face mask 150 and the PCBA board 120.

[0033] In this embodiment, refer to Figure 3 and Figure 5 The fixing component includes a screw 130. A connecting post 111 is provided on the bottom shell 110, and a threaded hole 112 is provided along the axis of the connecting post 111. A through hole is provided on the PCBA board 120. The screw 130 passes through the through hole and is threaded into the threaded hole 112. The head 142 of the screw 130 abuts against the PCBA board 120, thereby fixing the PCBA board 120 on the bottom shell 110.

[0034] It is understood that in this utility model, there are several buckle copper pillars 140 and screws 130 to ensure the stability of the connection between PCBA board 120 and bottom shell 110 and the stability of the connection between face shield 150 and PCBA board 120.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
