[0020] Please see Figure 1-3 As shown in one embodiment of this utility model, a fan assembly can be applied to an exhaust fan cabinet, including a fan 10 and a bracket 20. The fan 10 is installed inside the cabinet (not shown in the figure). The fan 10 includes a fixed end 11 for connecting to the cabinet and a suspended end 12 opposite to the fixed end 11. The bracket 20 includes a first connecting part 21 and a second connecting part 22 fixedly connected to the first connecting part 21. The first connecting part 21 supports the suspended end 12 of the fan 10, and the second connecting part 22 is used to abut against the inner wall of the cabinet (not shown in the figure). For ease of fixing, the first connecting part 21 and the second connecting part 22 can generally be set at a preset angle, in which case the first connecting part 21 and the second connecting part 22 can be fixed to different sides of the cabinet respectively.

[0021] In the above scheme, one end of the fan 10 is set as a fixed end 11 connected to the cabinet, and the other opposite end of the fan 10 is set as a suspended end 12 suspended in the cabinet. The first connecting part 21 of the bracket 20 supports the suspended end 12 of the fan 10, and the second connecting part 22 of the bracket 20 abuts against the cabinet shell wall. The suspended end 12 of the fan 10 is effectively supported. Without affecting the normal exhaust function of the fan 10, the stability of the fan 10 during operation is improved, the vibration of the fan 10 is reduced to extend the service life of the fan 10, and the noise caused by vibration and the impact of vibration on the surrounding environment of the cabinet are reduced.

[0022] Please see Figure 1As shown, in some embodiments, the fixed end 11 can be a mounting plate with an opening for the fan. The rear end and the suspended end 12 of the fan can be fixed to the fan plate, and the fan plate can be connected to the mounting plate by two U-shaped brackets.

[0023] It should be noted that, for the sake of describing the structure in the figure, three directions can be defined: left-right, up-down, and front-back. However, the actual placement is not limited to these directions. The front-back direction is the parallel direction of the fixed end 11 and the suspended end 12, and the first connecting part 21 of the bracket extends in the up-down direction. The left-right direction is perpendicular to the up-down and front-back directions.

[0024] Please see Figure 1-3 As shown, in one embodiment of this utility model, the first connecting part 21 includes a support plate 210 and folded plates 211 disposed on both sides of the support plate 210, and the second connecting part 22 includes a base plate 220 and bent plates 221 disposed on both sides of the base plate 220. The support plate 210 and the base plate 220 are perpendicular to each other and connected, and the folded plates 211 and the bent plates 221 are connected. By setting the support plate 210 of the first connecting part 21 and the base plate 220 of the second connecting part 22 at an angle and connecting them, and by connecting the folded plates 211 and the bent plates 221, a stable connecting structure is formed, which can effectively bear the weight of the fan 10 and evenly transmit the force to the second connecting part 22, thereby ensuring that the entire fan 10 assembly has good stability and reliability during operation, and avoiding the normal operation of the fan 10 due to structural loosening or instability.

[0025] As shown in the attached figure, the support plate 210 of the first connecting part 21 and the base plate 220 of the second connecting part 22 can be arranged perpendicularly and integrally connected.

[0026] Please see Figure 1-3As shown in one embodiment of this utility model, the end of the support plate 210 away from the base plate 220 is provided with a clearance hole 30 for avoiding the suspended end 12 of the fan 10. The clearance hole 30 allows the support plate 210 to precisely avoid the irregular part of the suspended end 12 of the fan 10, avoiding mechanical interference problems caused by shape mismatch, providing stable support conditions for the first connecting part 21, ensuring the normal installation and operation of the suspended end 12 of the fan 10, thereby effectively improving the overall structural stability and operational reliability of the fan 10, extending the service life of the fan 10, and reducing the risk of failure caused by mechanical interference. In a specific example, as shown in the figure, the clearance hole 30 can be an arc-shaped groove structure, such as opening an arc-shaped notch on the upper side of the support plate 210 to form an arc-shaped groove structure, so as to be locked on the lower side of the suspended end 12 and arranged around the lower side of the suspended end 12. Of course, the clearance hole 30 can also be other shapes, such as square or irregular structure, to fit the lower side of the suspended end 12, to surround the lower side of the suspended end 12 and to be fitted against it.

[0027] Please see Figure 1-3 As shown, in one embodiment of this utility model, the end of the support plate 210 away from the base plate 220 is further provided with a plurality of mounting through holes 40 arranged at equal intervals along the circumference of the clearance hole 30, and extending through the support plate 210 along its thickness direction, for passing through the screw or bolt shank to achieve connection. The plurality of mounting through holes 40 arranged at equal intervals along the circumference of the clearance hole 30 provides a convenient installation method for connecting the suspended end 12 of the fan 10 to the support plate 210. For example, bolt connection can be achieved through the mounting through holes 40, ensuring a firm and reliable connection between the suspended end 12 of the fan 10 and the support plate 210, further enhancing the overall stability of the fan 10 assembly. This not only improves installation efficiency but also facilitates subsequent maintenance and replacement work, enhancing the maintainability of the fan 10 assembly.

[0028] Please see Figure 1-3 As shown, in one embodiment of this utility model, the support plate 210 is provided with weight-reducing holes 50 for weight reduction. The weight-reducing holes 50 effectively reduce the weight of the fan 10 assembly, thereby reducing the pressure and impact of the fan 10 assembly on the cabinet shell wall, helping to reduce the burden on the cabinet when bearing the fan 10 assembly, and avoiding cabinet deformation or damage due to excessive weight. At the same time, weight reduction also facilitates the transportation and installation of the fan 10 assembly.

[0029] Furthermore, the periphery of the weight-reducing hole 50 can be provided with a folded edge 60. This folded edge 60 can be provided on one or more sides of the periphery of the weight-reducing hole 50, such as the upper and lower sides, or the left and right sides. Alternatively, the folded edge 60 can be provided on all three sides. The folded edge 60 increases the local rigidity of the support plate 210, effectively resisting the strength reduction caused by the weight-reducing hole 50. This allows the support plate 210 to maintain better stability and reliability when bearing the weight of the fan 10 and enduring various forces during operation, further improving the overall performance of the fan 10 assembly.

[0030] Please see Figure 1-3 As shown in one embodiment of this utility model, the weight-reducing holes 50 are square holes, circular holes, or other shaped holes. There are multiple weight-reducing holes 50, which are arranged at intervals along the length of the support plate 210, i.e., the left-right direction. As shown in the attached figure, two weight-reducing holes 50 can be arranged separately in the left-right direction. The square holes make the weight-reducing area more regular, facilitating manufacturing and avoiding stress concentration problems caused by irregular shapes of the weight-reducing holes 50. The spaced-out weight-reducing holes 50 can reasonably distribute the force on the support plate 210, further optimizing the mechanical properties of the support plate 210 and ensuring that it still has sufficient strength and stability after weight reduction.

[0031] In some embodiments, the support plate 210 has the folded plate 211 on both sides of its length direction; on both sides of the weight-reducing hole 50 in the length direction of the support plate 210, there are folded edges 60 that are aligned with the folding direction of the folded plate 211. As shown in the figure, both the folded plate 211 and the folded edge 60 are bent away from the fixed end 11. By forming multiple weight-reducing holes 50, multiple folded edges 60 can be formed to achieve a better strengthening effect.

[0032] Please see Figure 1-3 As shown, in one embodiment of this utility model, the fan 10 assembly further includes a first reinforcing rib 70. The two ends of the first reinforcing rib 70 are respectively connected to the folded plates 211 on both sides of the support plate 210, that is, the first reinforcing rib 70 extends to the left and right. The left end of the first reinforcing rib 70 is fixedly connected to the folded plate 211 on the left side, such as by welding or bolting. The right end of the second reinforcing rib 70 is fixedly connected to the folded plate 211 on the right side, such as by welding or bolting.

[0033] The two sides of the first reinforcing rib 70 are connected to the top of the folded edge 60 and the corresponding sides of the support plate 210, as shown in the attached figure. The front side of the first reinforcing rib 70 is abutted against the rear side of the support plate 210, and the connection is made by welding or bolts. Alternatively, it can be a simple abutment without a strong connection, which can provide some resistance to bending. The lower side of the first reinforcing rib 70 is connected to the top of the folded edge 60 by welding, bonding, or other methods. Alternatively, the lower side of the first reinforcing rib 70 and the top of the folded edge 60 can be a simple abutment without a strong connection, which can also provide some resistance to bending.

[0034] The above-mentioned configuration can effectively improve the strength of the support structure of the fan 10 assembly and enhance the connection between the support plate 210 and the folding plate 211. This structure has good stability and can effectively resist external forces, thereby ensuring that the fan 10 assembly will not loosen or deform due to vibration or external impact during operation, further improving the reliability and service life of the fan 10 assembly.

[0035] Please see Figure 1-3 As shown in one embodiment of this utility model, the fan assembly further includes a second reinforcing rib 80, which can be disposed at the junction of the first connecting part 21 and the second connecting part 22 to reinforce the junction. The two ends of the second reinforcing rib 80 are respectively connected to the folded plate 211 and the bent plate 221 on the corresponding sides. For example, the left end of the second reinforcing rib 80 is connected to the left folded plate 211 and the left bent plate 221, and the right end of the second reinforcing rib 80 is connected to the right folded plate 211 and the right bent plate 221. Specifically, on either the left or right side, the end face of the second reinforcing rib 80, the folded plate 211, and the bent plate 221 can be stacked in the left-right direction and fixedly connected; as shown in the attached figure, the folded plate 211 and the bent plate 221 can also form a spliced ​​relationship, and then be stacked with the end face of the second reinforcing rib 80.

[0036] The three sides of the second reinforcing rib 80 are respectively connected to the corresponding sides of the support plate 210, the corresponding sides of the base plate 220, and the bottom of the flange 60. As shown in the attached figure, the front side of the second reinforcing rib 80 is abutted against the rear side of the support plate 210, which can be through abutment, welding, screw connection, etc.; the lower side of the second reinforcing rib 80 is abutted against the upper side of the base plate 220, which can be through abutment, welding, screw connection, etc.; the upper side of the second reinforcing rib 80 is abutted against the lower end of the flange 60, which can be through abutment, welding, screw connection, etc. Preferably, the distance between the lower end of the flange 60 and the upper side of the base plate 220 is equal to the height of the second reinforcing rib 80. Preferably, both the second reinforcing rib 80 and the first reinforcing rib 70 are made of square tubing.

[0037] As described above, the two ends of the second reinforcing rib 80 are respectively connected to the folded plates 211 on both sides of the support plate 210 and the bent plates 221 on both sides of the bottom plate 220, and are connected to the bottom of the support plate 210, the bottom plate 220 and the folded edge 60 to form an integral reinforcing structure. This further enhances the strength of the support structure of the wind turbine 10 assembly, tightly connecting the first connecting part 21 and the second connecting part 22 together to form a more stable support system. Through the connection of the second reinforcing rib 80, various forces generated by the wind turbine 10 assembly during operation, including vibration and impact, can be effectively resisted, thereby ensuring the overall stability of the wind turbine 10 assembly and improving its operating performance under complex working conditions.

[0038] Please see Figure 1-3 As shown, in one embodiment of this utility model, the second connecting portion 22 has a rubber pad 90 on the side away from the first connecting portion 21. The rubber pad 90 can be stacked on the underside of the base plate 22 to achieve a shock absorption effect. The second connecting portion 22 is provided with a through hole for communication, through which screws or bolts for connection are arranged. That is, both the rubber pad 90 and the base plate 22 are provided with through holes, which are overlapped to form a through hole. Providing the rubber pad 90 on the side of the second connecting portion 22 away from the first connecting portion 21 can effectively reduce the impact of vibration generated during the operation of the fan 10 assembly on the surrounding environment of the cabinet. The rubber pad 90 has good shock absorption and buffering performance, and can absorb and isolate vibration energy, thereby reducing the amplitude and range of vibration propagation. This design can not only protect other equipment inside the cabinet from vibration interference, but also reduce noise generation, providing a quieter and more stable operating condition for the surrounding environment of the cabinet.

[0039] To facilitate punching and forming, the support plate 210 can be integrally connected with the folded plates 211 on both sides, the bottom plate 220 can be integrally connected with the bent plates 221 on both sides, and the support plate 210 can be integrally connected with the folded edge 60.

[0040] In some embodiments, a cabinet for exhaust fans is also provided, including a cabinet (the cabinet described above) and a fan assembly as described in any of the above embodiments. The fixed end 11 of the fan assembly is fixedly connected to the cabinet, and the second connecting portion 22 of the fan assembly abuts against the cabinet. Since the exhaust fan cabinet uses the fan assembly described above, please refer to the fan assembly described above for technical effects.

[0041] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
