[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0033] With the advancement of science and technology and the acceleration of industrialization, fans, as key power and ventilation equipment, play an indispensable role in daily life, commercial environment and industrial production. Axial fans, with their unique low pressure and large flow characteristics, have been widely used in air conditioning systems, household appliance cooling and ventilation and other fields. However, during the manufacturing and assembly process of fan components, the design and processing accuracy of motor brackets have become increasingly prominent, becoming an important factor restricting the improvement of fan performance and multi-scenario application.

[0034] The design of existing fan components often fixes the relative positions of the guide ring, mounting panel, fan blades and motor, making it difficult for the fan components to adapt to various usage scenarios after assembly. This design limitation restricts the versatility and flexibility of axial flow fans and cannot meet the market's growing demand for personalization and customization.

[0035] like Figure 1-6 As shown, the utility model proposes a fan assembly 2, which is mounted on a mounting frame 1. The fan assembly 2 includes:

[0036] Install the panel 22, the guide ring 23 and the rotating parts.

[0037] A mounting hole is provided in the middle of the mounting panel 22, and the mounting panel 22 is arranged on the mounting surface of the mounting frame 1. A guide ring 23 is arranged around the mounting hole, and the guide ring 23 is detachably arranged on the outer side or inner side of the mounting panel 22, so that the guide ring 23 is located outside or inside the mounting frame 1. The fan blade 25 of the rotating component is arranged in the guide ring 23.

[0038] like Figure 1-2 As shown, in this embodiment, the mounting frame 1 is composed of a plurality of connecting rods, the mounting frame 1 is a rectangular frame, and the top surface is a mounting surface for mounting the fan assembly 2. The mounting panel 22 is arranged on the top surface of the mounting frame 1. The mounting hole in the middle of the mounting panel 22 is circular, the guide ring 23 is annular, and the fan blade 25 of the rotating component is arranged in the mounting ring.

[0039] The installation panel 22 and the guide ring 23 are set as a split structure, so that the guide ring 23 can be set on the outer side or inner side of the installation panel 22 according to the actual scene, so as to realize different assembly methods. When the space problem does not need to be considered, the guide ring 23 is set on the outer side of the installation panel 22, and at this time, part of the structure of the fan assembly 2 protrudes from the installation surface of the mounting frame 1; when the space is small, the guide ring 23 is set on the inner side of the installation panel 22, so that the fan assembly 2 does not protrude from the mounting frame 1, and occupies less space, which can meet the installation requirements of the fan assembly 2 in a small space.

[0040] like Figure 3-4 As shown, the fan assembly 2 is supported by a support frame 29 .

[0041] The support frame 29 is used to support the rotating component, and the support frame 29 is connected to the inner side surface of the mounting panel 22. The support frame 29 is located inside the mounting frame 1.

[0042] The support frame 29 provides a stable support for the rotating parts, ensuring the stability and reliability of the motor of the fan assembly when running at high speed. It reduces the mechanical stress caused by vibration or imbalance and prolongs the service life of the fan assembly 2. And because the support frame 29 is located inside the mounting frame 1, it does not increase the external space occupied by the fan assembly 2, thereby maintaining the compactness of the design.

[0043] like Figure 3-4 As shown, the support frame 29 specifically includes: a fixing ring 292 and a support arm 291 .

[0044] The fixing ring 292 is in the shape of a circular ring sheet, and supports the motor 27 of the rotating component. The base of the motor 27 is inserted into the fixing ring 292, and the motor 27 and the fixing ring 292 are fixed together by the motor support feet 26. A plurality of support arms 291 are arranged at intervals around the fixing ring 292, and the support arms 291 are bent toward the direction of the mounting panel 22 and connected to the inner side surface of the mounting panel 22.

[0045] like Figure 6 As shown, the motor support foot is in a right angle shape, one outer wall of which is fixedly connected to the motor base, and the other outer wall is fixed to the fixing ring 292 of the support frame 29. The number of motor support feet can be set to multiple, and the more the number, the more stable the fan assembly can be during operation.

[0046] like Figure 3-4 As shown, a plurality of support arms 291 are arranged at intervals around the fixing ring 292, and these support arms 291 are bent toward the mounting panel 22 and connected to the inner side of the mounting panel 22, forming a stable support structure. This design greatly enhances the structural strength of the support frame 29, enabling it to better withstand the force and torque generated by the operation of the motor 27, and prevent damage caused by overload or vibration.

[0047] like Figure 1 As shown, the guide ring 23 is arranged on the outer side of the installation panel 22 , and the support frame 29 supports the motor 27 of the rotating component and is connected to the inner side of the installation panel 22 .

[0048] like Figure 2 As shown, in another embodiment, the guide ring 23 is arranged on the inner side of the mounting panel 22, and the fan assembly 2 also includes a support ring 24, which is arranged around the outer side of the guide ring 23, the support ring 24 is connected to the inner side of the mounting panel 22, and the support frame 29 is connected to the support ring 24.

[0049] like Figure 5 As shown, the support ring 24 includes two ring bodies arranged in parallel with each other, namely an upper ring body 241 and a lower ring body 243, and a plurality of support assemblies are arranged between the upper ring body 241 and the lower ring body 243. The upper ring body 241 of the support ring 24 is connected to the inner side of the mounting plate, and the lower ring body 243 is used to connect to the support frame 29. Each support assembly includes at least one support beam 242. The number of support assemblies is 2n, where n is the number of support arms 291 of the support frame 29.

[0050] The modular design of the support ring 24, the guide ring 23 and the support frame 29 makes the installation process easier and faster. Users can select appropriate components for assembly according to actual needs, which reduces the difficulty and cost of installation. This design has high flexibility and adaptability, and the fan assembly 2 can adapt to a variety of different installation environments and space conditions. Whether it is inside a large device or a small device, it can be flexibly installed and adjusted according to actual conditions.

[0051] like Figure 2-6 As shown, specifically, the guide ring 23 is connected to the inner side surface of the mounting panel 22, the support ring 24 is annularly surrounded by the outer side of the guide ring 23, the upper ring body 241 of the support ring 24 is connected to the inner side surface of the mounting panel 22, the lower ring body 243 of the support ring 24 is provided with a plurality of mounting holes at intervals, the support arm 291 of the support frame 29 is provided with mounting holes corresponding to the lower edge of the support ring 24, and the support arm 291 of the support frame 29 is screwed to the lower ring body 243.

[0052] The support frame 29 includes a fixing ring 292 and a support arm 291. A reinforcing member 28 is provided at the connection between the fixing ring 292 and the support arm 291. The reinforcing member 28 is in a long strip shape. A part of the reinforcing member 28 is fixed to the fixing ring 292 by screws, and another part is fixed to the support arm 291 by screws. The strength of the connection between the fixing ring 292 and the support arm 291 is strengthened to prevent the support frame 29 from being damaged due to the long-term vibration of the motor 27.

[0053] like Figure 6 As shown, the rotating components in this embodiment include: a motor 27 and fan blades 25.

[0054] The motor 27 is supported by a fixing ring 292 of the support frame 29, and its end is connected to the fixing ring 292. The fan blades 25 are connected to the rotor of the motor 27, and the fan blades 25 are located in the guide ring 23. The rotation of the motor 27 drives the fan blades 25 to rotate, so that the fan blades 25 rotate accordingly.

[0055] The fan assembly 2 of this embodiment further includes a mesh cover 21, which covers the guide ring 23. When the fan blades 25 rotate, the mesh cover 21 prevents dust in the air from gathering on the fan blades 25 and affecting the rotating parts.

[0056] like Figure 3-4 As shown, in a further embodiment, the support frame 29 is integrally formed. A reinforcing member 28 is also provided at the joint between the fixing ring 292 and the support arm 291, which can effectively reduce the deformation, warping and dimensional deviation that occur when welding between the various parts of the support frame, and effectively improve the manufacturing and assembly accuracy. The reinforcing member 28 is used to reinforce the key positions of the support frame to improve the strength of the support frame.

[0057] The reinforcing piece is in the shape of a long strip, one end of which is connected and fixed to the fixing ring, and the other end of which is fixed to the supporting arm.

[0058] like Figure 4 As shown, specifically, the support frame 29 is formed by CNC machine wire cutting of a whole metal plate and then bent. This design eliminates the welding process of the traditional support frame, which can effectively reduce the deformation, warping and dimensional deviation problems caused by welding between the various parts of the support frame 29, improve the processing accuracy of the support frame, and improve the processing efficiency of the support frame.

[0059] The utility model also provides an air conditioning system, comprising any one of the fan components 2 described above.

[0060] Compared with the prior art, the utility model proposes a fan assembly 2, which is installed on a mounting frame 1. The fan assembly 2 includes: a mounting panel 22, a guide ring 23 and a rotating component. The mounting panel 22 is arranged on the mounting surface of the mounting frame 1, and the guide ring 23 is arranged on the outer side or the front side of the mounting panel 22, so that the guide ring 23 is located outside or inside the mounting frame 1. This design enables the fan assembly 2 to better adapt to different installation environments and space conditions. Whether it is a spacious space or a narrow corner, the user can flexibly adjust the installation method and position of the fan assembly 2 according to actual conditions.
