Specific embodiments

[0018] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0019] Referring to the attached Figures 1 - 6 drawings, a fan blade assembly with 3D display function includes a fan blade component 3. The fan blade component 3 includes a rotating body 31. A plurality of blades 32 are evenly arranged in the circumferential direction of the rotating body 31. The rotating body 31 and the blades 32 are relatively fixed. When the blades 32 rotate, they are used for blowing air. A display circuit board 4 is installed on the front side of the rotating body 31, and a plurality of LED lamp beads are installed on the front side of the display circuit board 4.

[0020] In the above technical solution, the display circuit board 4 controls the lighting sequence of the LED lamp beads, thereby realizing the 3D display function.

[0021] In this embodiment, at least one edge of the front side of the blade 32 has an installation groove 321, and the display circuit board 4 has an extension part 41 corresponding to the installation groove 321 one by one. The extension part 41 is installed in the installation groove 321.

[0022] Furthermore, two installation grooves 321 are provided, and the two installation grooves 321 are respectively located on both sides of the rotating body 31.

[0023] Furthermore, the installation groove 321 is in a "C" - shaped structure.

[0024] In the above - mentioned technical solution, two installation grooves 321 are provided and symmetrically distributed, which can prevent violent vibration during the rotation of the fan blade component 3. The LED lamp beads are arranged on the main body of the display circuit board 4 and the extension part 41. In addition, the installation groove 321 is set in a "C" - shaped structure. During installation, the extension part 41 is installed inside the installation groove 321, which can protect the electronic components on the back of the extension part 41, preventing too much dust from sticking to it during long - term use and affecting the use.

[0025] In this embodiment, the front side of the rotating body 31 has an internal threaded column 322, and the screw 42 on the display circuit board 4 is threadedly connected to the internal threaded column 322, so that the display circuit board 4 is installed on the rotating body 31.

[0026] As Figure 1 、 Figure 2 and Figure 6 shown, the fan with 3D display function has a bracket base 1, and a drive assembly 2 is installed on the bracket base 1. The drive assembly 2 includes a housing 20 and a motor 22 installed inside the housing 20. When installing this fan blade assembly, the rotating body 31 is fixed to the output end of the motor 22, so that the motor 22 drives the rotating body 31 and the blade 32 to rotate, achieving the purpose of blowing air. At the same time, the display circuit board 4 can perform 3D display. For the power supply of the display circuit board 4, a wireless power supply method can be adopted, that is, a power output coil 6 is installed at the front end of the housing 20, and a power receiving coil 5 is installed at the rear end of the rotating body 31. The power output coil 6 is connected to the power supply, the power receiving coil 5 is connected to the display circuit board 4. When an alternating current flows through the power output coil 6 to generate magnetic flux, the power receiving coil 5 can generate an induced current. In addition, a conductive slip ring power supply method can also be adopted.

[0027] By installing the display circuit board 4 on the front side of the fan blade component 3, during the rotation of the fan blade component 3 and the display circuit board 4, it can not only blow air for heat dissipation, but also has a 3D display function, increasing the visual display effect of the fan, making it more attractive and visually impactful.

[0028] The above - described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
