[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] Example 1

[0039] See Figures 2-7 This embodiment discloses a transmission component 100 for assembly with fan blades 201 and for transmission connection with a fan drive source 303. The transmission component 100 includes a driven wheel 101 and an assembly. The assembly is connected to one side of the driven wheel 101; the fan blades 201 are fixedly connected to the assembly so that the fan blades 201 and the driven wheel 101 form a rotating unit; the driven wheel 101 is transmissionally connected to the fan drive source 303 and is rotatably connected to a fan bracket 304. In this embodiment, the pulley can be a belt pulley, sprocket, etc., but a belt pulley is preferred, allowing power transmission between the pulley and the drive source 303 via a belt.

[0040] Furthermore, the assembly in this embodiment includes multiple assembly parts 102, which are equidistantly arranged along the circumferential direction of the driven wheel 101. Each assembly part 102 is used to connect to a plurality of fan blades 201. This embodiment provides multiple independent assembly parts 102, which can be directly and fixedly connected to the fan blades 201 without the need for other assembly parts 102 in between, thus simplifying the fan structure. In other words, the fan blade assembly can be understood to mainly consist of two parts: each blade 201 and the transmission component 100 in this embodiment. Simply installing each blade 201 onto its corresponding assembly part 102 forms a fan blade assembly. In this embodiment, the assembly parts 102 and the blades 201 can be locked together using a detachable structure, such as bolts, nuts, screws, or snap-fit ​​fasteners.

[0041] Of course, as another implementation, the blades 201 can be assembled first to form a blade 201 as a whole, and then the blade 201 as a whole can be assembled on the assembly to form a fan blade assembly.

[0042] Furthermore, the transmission component 100 in this embodiment also includes a first seat 103. The first seat 103 is coaxial with the driven wheel 101, and the diameter of the driven wheel 101 is larger than that of the first seat 103. One end of each assembly part 102 is connected to the circumferential surface of the first seat 103, and the other end extends radially; in this embodiment, the assembly part 102 extends radially beyond the driven wheel 101, that is, the other end of the assembly part 102 exceeds the driven wheel 101; a connecting part 105 is provided between the side of each assembly part 102 facing away from the blade 201 and the driven wheel 101.

[0043] A second seat 104, coaxial with the first seat 103, is provided on the side of the first seat 103 facing away from the blade 201. The driven wheel 101 has a hollow center, and the second seat 104 extends axially to the hollow center of the driven wheel 101. Each assembly part 102 has a reinforcing rib 106 on the side facing away from the blade 201. The reinforcing rib 106 is connected to the connecting part 105, the back of the assembly part 102, the first seat 103, and the second seat 104. In this way, the assembly parts 102, the first seat 103, the second seat 104, and the driven wheel 101 are interconnected and form a reliable whole, which helps to improve the reliability of the entire transmission component 100.

[0044] Furthermore, the second housing 104 is provided with an axially extending mounting hole 107 for connection with a bearing. Thus, a bearing 108, such as a double-row angular contact ball bearing or other types of bearing, can be installed in the mounting hole 107 and then assembled with the fixed shaft 305 on the fan bracket 304, thereby enabling the rotation of the transmission component 100 in this embodiment. Furthermore, a bushing 109 can also be installed within the bearing 108 in the mounting hole 107 for easy assembly with the fixed shaft 305, and also to simplify the internal transmission components of the fan, requiring only a belt between the drive source 303 and the driven pulley 101 to drive the driven pulley 101 and the belt.

[0045] Example 2

[0046] See Figures 4-6This embodiment discloses a fan blade assembly 200, including the transmission component 100 of Embodiment 1 and a plurality of blades 201. Each blade 201 is equidistantly arranged along the circumferential direction and mounted on the side of each assembly part 102 facing away from the driven wheel 101. The fan blade assembly 200 of this embodiment integrates the blades 201 and the driven wheel 101 into a single unit, facilitating assembly, simplifying the structure, and reducing the need for complex transmission components with the drive source 303.

[0047] Example 3

[0048] See Figure 7 This embodiment discloses a plate fan 300, including the fan blade assembly 200, drive source 303, drive wheel 302, power transmission component 301, panel 306, bracket 304, etc., as described in Embodiment 2. Other parts of the plate fan 300 in this embodiment can be found in the prior art. In this embodiment, the drive wheel 302 is connected to the power output component of the drive source 303, and the power transmission component 301 is connected to the drive wheel 302 and the driven wheel 101 to transmit power. In this embodiment, the power transmission component 301 can be a belt, which wraps around the drive wheel 302 and the driven wheel 101. The drive source 303 can be a motor.

[0049] To facilitate the installation of components such as the drive source 303 and the transmission component 100, a bracket 304 is provided on the back of the fan blade assembly in this embodiment. The drive source 303 is mounted on the bracket 304; the bracket 304 is provided with a fixed shaft 305, and the driven wheel 101 is rotatably connected to the fixed shaft 305.

[0050] In this embodiment, the plate fan 300 achieves power transmission and rotation of the fan blade assembly by connecting the drive source 303 to the driven wheel 101 of the fan blade assembly. The transmission components between the fan blade assembly and the drive source 303 are simpler and less expensive than those in a traditional plate fan 300. For details, see... Figure 1 and Figure 7 In this embodiment, a belt is used to connect the driving wheel 302 and the driven wheel 101, so that the fan blade assembly can be driven by the driving source 303. Compared with the traditional plate fan 300, this embodiment only uses a bearing structure located in the second base 104, and the transmission structure is significantly simplified.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
