Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, and more specifically, it relates to a cooling fan bracket with a hinged connection structure. Background Technology

[0002] In the fields of industrial and commercial control equipment and residential smart devices, cooling fans are core vulnerable components that ensure stable operation of equipment and need to be replaced and maintained regularly at the installation site. Due to space-saving requirements, these devices are mostly wall-mounted, and the gap between the internal parts and the wall, as well as the surrounding operating space, are generally compact.

[0003] Common fan bracket solutions on the market adopt an integrated structure, which requires the entire device to be pulled out to replace the fan, and is prone to interference with internal cables and components; or they adopt a split structure, dividing the bracket into two components and connecting them with external hinges to reduce the pull-out volume; however, the traditional split fan bracket relies on external hinges, which increases costs and processes. External hinges need to be purchased separately, which not only increases the purchase cost, but also requires additional assembly of the hinges with the two brackets. Furthermore, the hinge installation requires aligning multiple sets of holes, and the large number of assembly screws makes the assembly process cumbersome. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cooling fan bracket with a hinge connection structure. This solves the technical problems in the prior art where traditional fan brackets rely on external hinges, increasing the cost of external purchases, and the need to align multiple sets of holes for hinge installation, resulting in a large number of assembly screws and a cumbersome assembly process.

[0005] The purpose and function of this utility model, a cooling fan bracket with a hinged connection structure, are achieved by the following specific technical means: A cooling fan bracket with a hinged connection structure includes a first fan bracket and a second fan bracket installed inside a wall-mounted unit. The first fan frame is slidably connected to the wall-mounted machine, and one end of the first fan frame is rotatably connected to the second fan frame through a connecting component. The connecting assembly includes two sets of hinge plates. The first fan frame and the second fan frame are respectively provided with two sets of hinge plates at their adjacent ends, and the two sets of hinge plates are rotatably connected.

[0006] According to a preferred embodiment, one set of hinge plates is provided with two sets of hinge bushings, and the other set of hinge plates is provided with two sets of hinge through holes corresponding to the two sets of hinge bushings. The two sets of hinge bushings are rotatably connected to the two sets of hinge through holes by two sets of hinge screws.

[0007] According to a preferred embodiment, each of the two sets of hinge bushings has a press-fit nut on an adjacent side, and one end of each of the two sets of hinge screws passes through the press-fit nuts and is inserted into the hinge through holes of the two sets.

[0008] According to a preferred embodiment, the distance between the two sets of press-fit nuts is greater than the distance between the two sets of hinge through holes.

[0009] According to a preferred embodiment, both the first fan frame and the second fan frame are provided with two sets of cooling fans.

[0010] According to a preferred embodiment, a bending plate is provided at one end of the second fan frame away from the first fan frame. The bending plate has four sets of fan socket slots corresponding to the four sets of cooling fans. Each of the four sets of fan socket slots has a fan socket, and the four sets of fan sockets are electrically connected to the four sets of cooling fans.

[0011] According to a preferred embodiment, the bending plate has eight sets of cable tie holes corresponding to the four sets of fan sockets, and four sets of cable ties are respectively threaded through the eight sets of cable tie holes, with the four sets of fan sockets respectively locked in the four sets of cable ties.

[0012] According to a preferred embodiment, both the first fan frame and the second fan frame are provided with multiple sets of stamped wire tie bridges.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the connecting components, the first fan bracket and the second fan bracket are formed into two sets of hinge plates by sheet metal bending. The hinge bushing on one set of hinge plates directly engages with the hinge through hole of the other set, and the rotation function is achieved by connecting with hinge screws. This solves the problem that traditional cooling fan brackets need to purchase hinges separately, saving the purchase cost of external hinges.

[0014] 2. By axially aligning the hinge bushing on one set of hinge plates with the hinge through hole on another set of hinge plates, and then tightening the two sets of hinge screws through the rivet nuts and hinge through holes, the connection can be completed. This solves the problem of aligning multiple sets of holes required for the external hinge assembly of traditional fan brackets. Typically, each set of hinges requires 8 screws for fixing, and the whole assembly requires 16 screws. The two sets of hinges are fixed on the first fan bracket and the second fan bracket respectively, simplifying the assembly process and reducing assembly steps.

[0015] 3. Because the hinge plate is a structure formed by bending sheet metal into one piece between the first fan frame and the second fan frame, rather than the separate assembly of the external hinge and the bracket in the traditional solution, the structural strength of the connection part is higher, and it is not easy for the hinge to loosen or fall off due to the vibration of the equipment during long-term operation; at the same time, the distance between the two sets of rivet nuts is greater than the distance between the two sets of hinge through holes, which can limit the relative displacement of the two fan frames in the vertical direction without affecting the rotation function, further avoiding gaps or jamming at the connection part.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] Example:

[0020] As attached Figure 1 To be continued Figure 7 As shown: This utility model provides a cooling fan bracket with a hinged connection structure, including a first fan bracket 12 and a second fan bracket 13 installed in a wall-mounted machine 11; the first fan bracket 12 is slidably connected to the wall-mounted machine 11, and one end of the first fan bracket 12 is rotatably connected to the second fan bracket 13 through a connecting component; the connecting component includes two sets of hinge plates 21, and the adjacent ends of the first fan bracket 12 and the second fan bracket 13 are integrally formed with two sets of hinge plates 21 by sheet metal bending, and the two sets of hinge plates 21 are rotatably connected.

[0021] Please refer to, for example Figure 6 and Figure 7 As shown, one set of hinge plates 21 is provided with two sets of hinge bushings 22, and the other set of hinge plates 21 is provided with two sets of hinge through holes 23 corresponding to the two sets of hinge bushings 22. The two sets of hinge bushings 22 are rotatably connected to the two sets of hinge through holes 23 by two sets of hinge screws 24. Each side of the two sets of hinge bushings 22 is provided with a press-fit nut 25. One end of each set of hinge screws 24 passes through the threaded hole of the two sets of press-fit nuts 25 and then passes into the two sets of hinge through holes 23. This eliminates the need for additional tapping on the hinge plates 21, simplifying the processing procedure. The distance between the two sets of press-fit nuts 25 is greater than the distance between the two sets of hinge through holes 23. Without affecting the rotation of the two sets of hinge plates 21 around the screws, the relative displacement of the first fan frame 12 and the second fan frame 13 in the vertical direction can be restricted.

[0022] Specifically, during assembly, the hinge plates 21 of the first fan frame 12 and the second fan frame 13 are first fitted together, ensuring that the hinge bushing 22 and the hinge through hole 23 are coaxially aligned. Then, the two sets of hinge screws 24 are screwed into the rivet nuts 25 until the screw ends pass through the hinge through hole 23, thus completing the rotational connection between the first fan frame 12 and the second fan frame 13. In this process, the first fan frame 12 and the second fan frame 13 form the hinge plates 21 by bending their own sheet metal, rather than using the traditional method. In this design, the external hinges need to be fixed to the two sets of brackets with multiple screws. The structural strength of the connection is higher, and the hinges are less likely to loosen or fall off due to vibrations caused by the long-term operation of the wall-mounted machine 11. At the same time, the assembly of the external hinges of traditional cooling fan brackets requires aligning multiple sets of holes. Usually, each set of hinges requires 8 screws for fixing. Connecting the first fan bracket 12 and the second fan bracket 13 to install two hinges requires 16 screws. However, this cooling fan bracket only requires two hinge screws 24 and does not require repeated hole calibration, reducing assembly time.

[0023] Please refer to, for example Figure 1 , Figure 2 and Figure 5As shown, both the first fan bracket 12 and the second fan bracket 13 are equipped with two sets of cooling fans 14. The end of the second fan bracket 13 away from the first fan bracket 12 is formed by bending sheet metal to form an oblique bending plate 15. The bending plate 15 has four sets of rectangular fan socket slots 16. Four sets of fan sockets 17 are respectively embedded in the four sets of fan socket slots 16. The four sets of fan sockets 17 are electrically connected to the four sets of cooling fans 14. The bending plate 15 has eight sets of cable tie holes 18 corresponding to the four sets of fan sockets 17. Four sets of nylon cable ties 19 are passed through the eight sets of cable tie holes 18. After each set of cable ties 19 passes through the two cable tie holes 18 on the left and right sides of the corresponding fan socket 17, it is tightened and the excess part is cut off, so that the four sets of fan sockets 17 are respectively locked in the four sets of cable ties 19, preventing the fan sockets 17 from falling out of the slots or shifting due to vibration when the wall-mounted machine 11 is running.

[0024] Both the first fan frame 12 and the second fan frame 13 have multiple sets of stamped wire tie bridges 20 formed by stamping process. The multiple sets of stamped wire tie bridges 20 are distributed around the first fan frame 12 and the second fan frame 13. In use, the wires connecting the cooling fan 14 and the fan socket 17 are passed through the stamped wire tie bridges 20 on the corresponding paths in sequence. The stamped wire tie bridges 20 are used to organize and limit the wires, preventing the wires from falling apart. At the same time, the organized wires are neatly arranged, and when it is necessary to replace the cooling fan 14 or repair the socket, the corresponding wires can be quickly identified without spending time organizing the tangled cables, thus improving maintenance convenience.

[0025] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
