Description

Technical Field

[0001] The utility model belongs to the technical field of LED display screens, and particularly relates to a bottom shell kit of an outdoor LED module. Background Art

[0002] LED display is a display method that controls semiconductor light emitting diodes. It is composed of tens to hundreds of thousands of semiconductor light emitting diode pixels evenly arranged. LED display is favored by a wide range of users due to its high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance. With the rapid development of the entertainment and advertising industries, especially TV stations, evening parties, stages or large outdoor advertising sites, large-screen displays are required.

[0003] Traditional outdoor LED display modules are mostly fixed with positive locking screws. This solution requires that the product spacing and the corresponding hole position of the bottom shell must be precisely matched, which increases the complexity of mold design and manufacturing costs. In addition, the outdoor module kits commonly used in the market generally adopt a thin-wall design to reduce weight and cost, but this design is easily damaged during transportation and has relatively high requirements for the injection molding process. The thin-wall design also results in less than ideal strength of the bottom shell. More importantly, if the PCB in the module ages and deforms due to long-term use or environmental factors, it will directly affect the flatness of the entire display module. The decrease in flatness will significantly affect the display effect and user experience. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] See also Figures 1 to 4 As shown, a bottom shell kit of an outdoor LED module includes:

[0026] Module bottom shell 1;

[0027] A top groove 2 is formed at the top of the module bottom shell 1. Positioning posts 3 are installed at the four corners of the bottom groove wall of the top groove 2. A plurality of first mounting blocks 5 and a plurality of second mounting blocks 6 are provided on the four sides of the bottom groove wall of the top groove 2. A mounting hole 7 is formed in the middle of the top of the plurality of first mounting blocks 5 and the middle of the top of the plurality of second mounting blocks 6.

[0028] The support frame 4 is arranged in the middle of the bottom groove wall of the top groove 2, and the support frame 4 plays a stable supporting role for the PCB board of the LED display screen.

[0029] Depend on Figure 1 and Figure 2 It can be seen that several first fixing frames 8 are provided in the middle of the top of the support frame 4, several first reinforcement frames 9 are provided on both sides of the top of the support frame 4, and several fixing blocks 10 are provided at the top of the support frame 4. Fixing holes 11 are opened in the middle of the top of the several fixing blocks 10.

[0030] As can be seen from the above, the installation of the LED display screen and the module bottom shell 1 is achieved by setting the mounting holes 7 on several first mounting blocks 5 and several second mounting blocks 6, in conjunction with the fixing holes 11 opened by several fixing blocks 10 fixed on the module bottom shell 1. This design cleverly utilizes the mounting holes 7 and fixing holes 11 located at different positions, so that the module bottom shell 1 can be compatible with products of various spacings in hole design, breaking the traditional one-to-one design pattern of outdoor product spacing and bottom shell. In addition, the module bottom shell 1 adopts a back-locking screw solution for installation with the LED display screen, which further simplifies the compatibility process of various spacing holes, thereby reducing the complexity and manufacturing cost of the design of the module bottom shell 1.

[0031] Specifically, refer to Figure 1 and Figure 2 As shown, several first fixing frames 8 are arranged as a herringbone structure, several first reinforcement frames 9 are arranged as a Y-shaped structure, and the height of the first mounting block 5 and the height of the second mounting block 6 are consistent with the thickness of the module bottom shell 1.

[0032] From the above, it can be seen that the first fixing frame 8 and the first reinforcement frame 9 can reinforce the top of the support frame 4, which can improve the firmness of the support frame 4, so that the first mounting block 5 and the second mounting block 6 can cooperate with the support frame 4 to achieve a firm installation between the module bottom shell 1 and the LED display screen.

[0033] Example 2:

[0034] refer to Figure 3 and Figure 4 As shown, a bottom groove 12 is provided at the bottom end of the module bottom shell 1, a plurality of second reinforcement frames 13 are provided on the top groove wall of the bottom groove 12, and a plurality of fixing plates 14 are provided on both sides of the bottom end of the support frame 4;

[0035] A plurality of side grooves 15 are formed on the lower portion of the outer surface of the module bottom shell 1 , and a second fixing frame 16 is provided at the middle portion of the bottom end of the supporting frame 4 .

[0036] As can be seen from the above, the support frame 4 is fixed and reinforced by a plurality of second reinforcement frames 13 and a plurality of second fixing frames 16, which significantly improves the firmness of the support frame 4. Subsequently, the support frame 4 firmly supports the module bottom shell 1, thereby strengthening the overall structural strength of the module bottom shell 1. The module bottom shell 1 adopts an innovative back-locking screw solution in structural design, abandoning the original thin-walled structure, making the bottom shell structure more concise, not only facilitating daily production, but also significantly improving the product yield. This design makes the module bottom shell 1 more resistant to damage during transportation, and the requirements for the injection molding process are relatively low. At the same time, the module bottom shell 1 has excellent strength, that is, It prevents the PCB in the LED module from aging and deformation due to long-term use or environmental factors, and can also ensure the flatness of the entire display module, thereby guaranteeing the display effect and user experience of the LED display. In addition, the side of the module bottom shell 1 is cleverly designed with several serrated side grooves 15. When GOB glue is used for glue filling, these serrated side grooves 15 effectively enhance the adhesion between the GOB glue and the module bottom shell 1, making the glue filling effect more excellent, and also making the finished product waterproof and overall appearance better. In terms of appearance design, the module bottom shell 1 adopts a combination of hard lines. The overall design is simple and layered, and it is highly recognizable.

[0037] Preferably, reference Figure 3 and Figure 4 As shown, the plurality of second reinforcement frames 13 are all configured as a cross-shaped structure, the second fixing frame 16 is composed of a long rod and a plurality of short rods, and the plurality of side grooves 15 are all configured as a sawtooth shape.

[0038] As can be seen from the above, the second reinforcement frame 13 and the second fixing frame 16 can reinforce and fix the bottom of the support frame 4, which can further improve the firmness of the support frame 4, and is conducive to the stable support of the LED module by the support frame 4. The serrated side grooves 15 increase the adhesion of the GOB glue and the module bottom shell 1, making the glue filling effect better and effectively improving the waterproof performance of the module bottom shell 1.

[0039] Application examples:

[0040] This design is used in harsh outdoor environments, such as urban lighting, billboards and signs, and building exterior wall decoration. Its waterproof performance and sturdy structure ensure that the LED display can still operate stably in various harsh climates, extending the product's service life. The module bottom shell 1 adopts a new back-locking screw solution, which simplifies the bottom shell structure and improves production efficiency. At the same time, it enhances the structural stability of the module and reduces deformation or damage caused by thin-walled structures. The innovation in the hole design of the module bottom shell 1 enables the same bottom shell to adapt to seven LED products with different spacings, improving production flexibility and cost control efficiency. In addition, the module bottom shell 1 adopts a special GOB glue filling process, eliminating the thin-wall design and reducing the risk of water leakage. At the same time, the side grooves 15 with a serrated design on the side enhance the adhesion between the glue and the bottom shell, further improving the waterproof performance and overall appearance. This allows the module bottom shell 1 to effectively prevent moisture penetration in heavy rain or long-term humid environments, ensuring that the internal circuit of the LED module is not damaged and maintaining long-term stable operation.
