[0001] This utility model relates to the field of backplate structure technology, and in particular to an LED screen backplate structure with heat dissipation function. Background Technology

[0002] LED screens, as outstanding representatives of modern display technology, are widely used in various fields such as indoor and outdoor advertising, stage performances, film and television production, and information display due to their advantages such as high brightness, high contrast, long lifespan, and energy saving and environmental protection. The LED screen backplate, as a key component supporting and protecting the LED modules, not only bears the structural strength of the entire screen but also plays an important role in heat dissipation and electrical connection. Its rational design directly affects the performance, lifespan, and ease of maintenance of the LED screen.

[0003] Traditional LED screen backplate structures have significant shortcomings in heat dissipation design. Especially when the cooling fan, a critical heat dissipation component, fails, the entire LED screen backplate often needs to be disassembled to repair or replace it, as the backplate is tightly integrated with the screen body. This process is not only cumbersome and time-consuming but also increases maintenance costs and reduces the screen's maintainability and operational flexibility. Furthermore, frequent disassembly can damage the screen structure, affecting its overall stability and safety. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0023] like Figures 1 to 6 As shown, an LED screen back panel structure with heat dissipation function includes a back panel 1. A partition plate 2 is fixedly installed on the inner wall of the back panel 1 by bolts. A back frame 3 is fixedly installed on the back of the back panel 1. Dustproof nets 4 are fixedly embedded on both the left and right sides of the back frame 3. A sliding groove 5 is opened through the top surface of the back frame 3. A fan mounting plate 6 is slidably connected to the inner wall of the sliding groove 5. Several linear array cooling fans 7 are embedded inside the fan mounting plate 6. The cooling fans 7 are all corresponding to the partition plate 2. A cover plate 8 is fixedly connected to the top of the fan mounting plate 6. The bottom surface of the cover plate 8 is in contact with the top surface of the back frame 3. Two symmetrically arranged frames 9 are fixedly connected to the top surface of the back frame 3. A control plate 10 is slidably connected to the inner wall of each frame 9. A spring 11 is fixedly connected between the control plate 10 and the frame 9. A locking plate 12 is fixedly connected to the side of each control plate 10 away from the spring 11. Both locking plates 12 penetrate the frame 9 and are engaged with the cover plate 8.

[0024] As an optional technical solution of this utility model, a positioning pin 13 is fixedly connected to the top of the fan mounting plate 6, and a positioning hole 14 is provided on the inner wall of the back frame 3. The positioning pin 13 is slidably connected to the back frame 3 through the positioning hole 14. This design allows the fan mounting plate 6 to be accurately and stably slidably connected to the back frame 3. The positioning pin 13 ensures the accuracy of the fan mounting plate's position during installation, while the positioning hole 14 provides a path for sliding connection, making the installation and disassembly process smoother and less prone to errors.

[0025] As an optional technical solution of this utility model, a sealing gasket 15 is fixedly connected to the top surface of the cover plate 8, and a sealing groove 16 is formed on the top surface of the back frame 3. The sealing gasket 15 is slidably connected to the back frame 3 through the sealing groove 16. This design enhances the sealing performance between the cover plate 8 and the back frame 3, effectively preventing dust, moisture, and other impurities from entering the interior of the screen back panel structure, thereby protecting the LED screen and its components from damage. The soft material of the sealing gasket 15 can fill any tiny gaps, ensuring a sealing effect.

[0026] As an optional technical solution of this utility model, locking grooves 17 are provided on both the left and right sides of the cover plate 8. Two locking plates 12 penetrate the frame 9 and are engaged with the cover plate 8 through the locking grooves 17. This design provides a simple and effective locking mechanism to ensure that the cover plate 8 can be firmly fixed to the back frame 3 when closed. The locking plates 12 achieve a firm connection between the cover plate and the back frame by penetrating the frame 9 and engaging in the locking grooves 17, thereby enhancing the stability and safety of the entire back plate structure.

[0027] As an optional technical solution of this utility model, the inner wall of the back frame 3 has two symmetrically arranged guide grooves 18. Guide plates 19 are fixedly connected to both the left and right sides of the fan mounting plate 6. The two guide plates 19 are slidably connected to the back frame 3 through the two guide grooves 18. This design makes the sliding of the fan mounting plate 6 within the back frame 3 more stable and controllable. The guide grooves 18 provide a clear sliding path for the guide plates 19, ensuring the accuracy of the fan mounting plate's position during installation and disassembly, while reducing friction and wear, and extending the service life of the components.

[0028] As an optional technical solution of this utility model, a number of symmetrically arranged pins 20 are fixedly connected to the back of the partition plate 2, and a number of symmetrically arranged pin sleeves 21 are fixedly connected to the inner wall of the back frame 3. The pins 20 are respectively inserted into the pin sleeves 21. This design provides a simple and effective connection method for fixing the relative position between the partition plate 2 and the back frame 3. The insertion of the pins 20 into the pin sleeves 21 ensures the stability and firmness of the partition plate during installation. This connection method is not only easy to operate, but also provides sufficient strength to support the weight of the LED screen and its components.

[0029] An LED screen backplate structure with heat dissipation function works on the following principle:

[0030] 1): When it is necessary to inspect the heat dissipation fan 7 inside the back panel structure, the staff first presses the control board 10 to squeeze the spring 11. As the spring 11 is compressed, it can drive the locking plate 12 to move out of the locking groove 17, which can release the lock on the cover plate 8.

[0031] 2): Pull the cover plate 8 upwards to pull the fan mounting plate 6 out of the slide 5, which can quickly remove the cooling fan 7 from the back frame 3. The cooling fan 7 can be inspected or replaced without removing the entire LED screen back panel.

[0032] 3): After the cooling fan 7 has been repaired, the fan mounting plate 6 can be reset, which can achieve quick installation of the cooling fan 7 and is extremely convenient to operate.

[0033] In summary, this LED screen backplate structure with heat dissipation function allows for easy maintenance of the cooling fan 7 inside the backplate. First, the operator presses the control panel 10 to compress the spring 11. As the spring 11 is compressed, the locking plate 12 moves out of the locking groove 17, releasing the lock on the cover plate 8. Then, pulling the cover plate 8 upwards causes the fan mounting plate 6 to be pulled out from the slide groove 5, allowing for quick removal of the cooling fan 7 from the back frame 3. Maintenance or replacement of the cooling fan 7 can be performed without removing the entire LED screen backplate. After maintenance, the fan mounting plate 6 can be reset, enabling rapid installation of the cooling fan 7. The operation is extremely convenient. The engagement between the pin 20 and the pin sleeve 21 provides a simple and effective connection method for fixing the relative position between the partition plate 2 and the back frame 3. The pin 20 is inserted into the pin sleeve 21, ensuring the stability and firmness of the partition plate during installation. This connection method is not only easy to operate but also provides sufficient strength to support the weight of the LED screen and its components.
