[0034] The following is an intelligent information communication chassis provided by this utility model, which can solve the above technical problems.
[0035] Please refer to Figure 1 and Figure 2 , the design of the intelligent information communication chassis in this embodiment follows the principles of modularization and heat dissipation optimization. The intelligent information communication chassis includes an installation structure for multi-layer circuit boards. In the installation structure of the multi-layer circuit boards, circuit board 1 is firmly fixed on the bottom plate 2 through a carefully designed mounting bracket 3. A number of mounting brackets 3 are installed along the vertical direction at the top of the bottom plate 2. The side wall of the mounting bracket 3 is provided with a number of limiting convex edges 4 formed by flanging, and a limiting track 5 is provided between adjacent limiting convex edges 4. Circuit board 1 is installed in the limiting track 5. The limiting track 5 is horizontally arranged. One end of a number of mounting brackets 3 is all connected to the same through a connecting plate 6. The ends of two adjacent mounting brackets 3 away from the connecting plate 6 are installed with the same end cover plate 7. The end cover plate 7 is arranged facing the circuit board 1, forming a structure that is both stable and easy to maintain. Circuit board 1 is accurately limited in the limiting track 5 of the mounting bracket 3. Circuit board 1 is limited between the end cover plate 7 and the connecting plate 6, ensuring the stability and easy maintainability of the circuit board 1.
[0036] Please refer to Figure 2 and Figure 5 , the intelligent information communication chassis is composed of key components such as the bottom plate 2, the U-shaped cover plate 8, and the front cover plate 9. They jointly form a closed and protective space, providing comprehensive protection for the internal circuit board 1 and electronic components. Among them, the U-shaped cover plate 8 is closely matched with the bottom plate 2 to form the main body part of the chassis, and it is also fixedly connected to the top of the mounting bracket 3. The front cover plate 9 is installed between the U-shaped cover plate 8 and the bottom plate 2, and it is parallel to the connecting plate 6, further enhancing the structural strength and stability of the chassis.
[0037] Please refer to Figure 3 and Figure 8, in terms of heat dissipation, this design also performs excellently. At one end of the top of the bottom plate 2, a fan frame 10 is fixedly installed, which is equipped with an efficient heat dissipation fan 11 inside. The side wall of the fan frame 10 is provided with a first heat dissipation channel 12, and the mounting frame 3 is provided with a second heat dissipation channel 13. These channels and the heat dissipation holes 14 on the side walls at both ends of the U-shaped cover plate 8 together form an effective heat dissipation path, ensuring that the heat inside the chassis can be discharged in time, thereby maintaining the temperature stability inside the chassis.
[0038] Please refer to Figure 5 , in addition, this design also takes into account the convenience of installation and the flexibility of use. L-shaped mounting plates 16 are fixedly installed on both sides of the U-shaped cover plate 8, and mounting holes 17 are provided on them, which facilitates the easy installation of the entire chassis module into the cabinet. At the same time, the U-shaped cover plate 8, the mounting frame 3, and the fan frame 10 are all made of sheet metal parts, which are not only easy to process and manufacture, but also have high strength and good heat dissipation performance.
[0039] Please refer to Figure 6 , in the detail design, upper bending parts 18 and lower bending parts 19 perpendicular to the end cover plate 7 are respectively provided at the top and bottom of the end cover plate 7. The upper bending parts 18 and lower bending parts 19 of adjacent end cover plates 7 are in contact with each other, making the installation of the end cover plate 7 more stable and reliable. A threaded sleeve 20 for fixing the circuit board 1 is also riveted and fixed on the lower bending part 19. This design facilitates the firm connection of the circuit board 1 and the end cover plate 7 through screws.
[0040] Please refer to Figure 1 and Figure 3 , in this embodiment, two adjacent end cover plates 7 share screws. A limiting plate 27 is sleeved on the screws. The screws fixedly connect one end cover plate 7 with the corresponding mounting frame 3. At the same time, the screws form a fixed fit between an adjacent end cover plate 7 and the corresponding mounting frame 3 through the limiting plate 27. Limiting blocks are provided on the limiting plate 27, and limiting holes 28 connected to the limiting blocks are provided on an adjacent end cover plate 7, saving the number of screws and reducing the workload of disassembly and assembly.
[0041] Please refer to Figure 1 and Figure 7, the fixation of solid-state drives in the prior art requires the use of screws, making disassembly and assembly rather troublesome. In this embodiment, a clever fixing bracket 21 is also fixed on the circuit board 1. One end of the fixing bracket 21 is hinged with a clamping plate 22, and it internally has a fixed hard disk installation groove 23. A clamping groove 24 is also provided at one end of the fixing bracket 21, while a clamping plate 25 that cooperates with the clamping groove 24 is provided at one end of the clamping plate 22. Through the design of the clamping plate 22, the fixed hard disk can be conveniently fixed in the fixed hard disk installation groove 23 and connected to the circuit board 1 through a data cable. The snap-fit cooperation between the clamping groove 24 and the clamping plate 25 further simplifies the installation and disassembly process. At the same time, a pick-and-place notch 26 is also provided on the fixing bracket 21, and this design makes the pick-and-place of the solid-state drive more convenient and fast.
[0042] The installation structure of the multi-layer circuit board and the design of the intelligent information communication chassis in this embodiment are based on the principles of modularization and heat dissipation optimization. The circuit board 1 is fixed on the bottom plate 2 through the mounting bracket 3, and each mounting bracket 3 is connected by a connecting plate 6 to form a stable structure. The circuit board 1 is limited within the limiting track 5 of the mounting bracket 3 and fixed by the end cover plate 7 and screws to ensure the stability and easy maintenance of the circuit board 1. The intelligent information communication chassis is composed of components such as the bottom plate 2, the U-shaped cover plate 8, and the front cover plate 9, forming a closed space to protect the internal circuit board 1 and electronic components.
[0043] In terms of heat dissipation, the cooling fan 11 in the fan bracket 10 forms an effective heat dissipation path through the first heat dissipation channel 12, the second heat dissipation channel 13, and the heat dissipation holes on the U-shaped cover plate 8, ensuring that the heat inside the chassis can be discharged in time and maintaining the temperature stability inside the chassis.
[0044] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention.
