Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a freely spliced waterproof display screen. Background Art

[0002] With the development of information technology and its diverse application scenarios, display screens, as essential tools for information display, have gained widespread use in fields such as outdoor advertising, public information dissemination, and industrial control. However, traditional display screens often perform poorly in adverse weather conditions (such as rain and humidity), prone to water damage, resulting in a shortened service life or even malfunction. Furthermore, fixed-size display screens struggle to meet user demands for flexible layouts, especially when constructing large display walls or custom-shaped display areas.

[0003] While some waterproof display screens exist on the market, most rely on simple sealing to achieve a certain degree of waterproof protection. This approach not only increases manufacturing costs but also poses the risk of leakage during long-term use. Furthermore, these displays typically lack modularity, making it difficult for users to quickly disassemble and assemble them to meet specific needs, significantly limiting their application scope and development potential.

[0004] In view of the above problems, there is an urgent need to develop a new display screen device that has good waterproof performance and can be easily and freely spliced, so as to better serve various complex and changing application scenarios. Utility Model Content

[0006] The present invention provides a freely splicable waterproof display screen, specifically comprising an electrical cabinet, a base, a display screen module, and a mounting shell. The base is horizontally mounted on the top of the electrical cabinet, and the display screen module is fixedly mounted on the base via the mounting shell. The display screen module comprises a display screen, a back cover, a sealed compartment, a partition, a heat dissipation module, and a circuit module. The partition is mounted between the display screen and the back cover, and a heat dissipation compartment is formed between the back cover and the partition. The back cover is provided with a plurality of air outlets and air inlet holes. The heat dissipation module is mounted on the air inlet holes of the back cover. The circuit module is mounted in the sealed compartment, and the sealed compartment is mounted on the back of the back cover. The display screen is connected to the circuit module via a waterproof cable, and the circuit module is connected to the circuit inside the electrical cabinet via a waterproof connector.

[0007] Further describing the above solution, the mounting shells are fixed by bolts on the sides, and a cover plate is also provided on the back of the mounting shells.

[0029] See also Figures 1-9 As shown, the present invention provides a waterproof display screen that can be freely spliced, specifically comprising an electrical cabinet 1, a base 11, a display screen module, and a mounting shell 4. The base 11 is horizontally mounted on the top of the electrical cabinet 1, and the display screen module is fixedly mounted on the base 11 through the mounting shell 4. Figure 6 、 7 As shown, the display screen module includes a display screen 2, a back cover 21, a sealed chamber 22, a partition 25, a heat dissipation module 23, and a circuit module 223. The partition 25 is installed between the display screen 2 and the back cover 21, and a heat dissipation chamber 251 is formed between the back cover 21 and the partition 25. The back cover 21 is provided with a plurality of air outlets 211 and air inlet holes. The heat dissipation module 23 is installed on the air inlet holes of the back cover 21. The circuit module 223 is installed in the sealed chamber 22, and the sealed chamber 22 is installed on the back of the back cover 21. The display screen 2 is connected to the circuit module 223 via a waterproof cable, and the circuit module 223 is connected to the circuit inside the electrical cabinet 1 via a waterproof connector 221. Figure 2 As shown, the mounting shells 4 are fixed by bolts on the sides, and a cover plate 3 is also provided on the back of the mounting shell 4 .

[0030] The sealed compartment 22 is provided with a sealed compartment cover 222 and a sealing strip 224. The sealed compartment cover 222 seals the sealed compartment 22 via the sealing strip 224, facilitating maintenance of the circuit module 223. The heat dissipation module 23 includes a fan 232 and a fan cover 233. The fan 232 is connected to the circuit module 223 via a waterproof connector 221. The fan cover 233 wraps the fan 232 around the rear cover 21. The fan 232 blows air into the heat dissipation compartment 251.

[0031] A sealing ring 252 is provided between the partition 25 and the rear cover 21 to seal the heat dissipation chamber 251. In this embodiment, the air outlets 211 are located on both sides of the rear cover 21, the sealed chamber 22 is installed in the center of the rear cover 21, and the heat dissipation module 23 abuts the side of the sealed chamber 22. The rear cover 21 is also provided with a handle 24, and the electrical cabinet 1 is also provided with a cabinet door 12. The base 11 is elongated, and the bottom of the mounting shell 4 is fixed to the base 11 by bolts, and the mounting shells 4 are fixed to each other by bolts.

[0032] In order to have a more thorough and comprehensive understanding of the disclosure of the present invention, the principle thereof will be further explained below in conjunction with the usage.

[0033] During assembly, select a base 11 of appropriate length, then fix the electrical cabinet 1, and then fix the base 11 on the top of the electrical cabinet 1. Figure 4 As shown, the display screen module is installed in the installation shell 4, and then the installation shell 4 is fixed on the base 11. The adjacent installation shells 4 are also fixed by bolts. The electric cabinet 1 is connected to the display screen module circuit, and the cover plate 3 is covered on the back of the installation shell 4.

[0034] When using, such as Figure 7-Figure 9 As shown, fan 232 draws external air into heat dissipation chamber 251. This air flows through heat dissipation chamber 251, removing heat generated by display screen 2 and circuit module 223, achieving rapid heat dissipation. Furthermore, heat dissipation chamber 251 is designed independently from display screen 2 and circuit module 223. Therefore, the ingress of water or dust into the heat dissipation chamber does not affect the operation of display screen 2. This modular design allows for adjustment of the number of screens as needed, making installation and maintenance both convenient and easy.
