[0061] [Retractable elastic member 9]

[0062] Reference Figure 5 and Figure 6 As shown, the retractable elastic member 9 includes a retractable elastic connection part 91 extending from the middle part in the spiral direction. It can also be said that the retractable elastic connection part 91 is spiral, and the retractable elastic connection part 91 is made of elastic material, and the number of turns of the retractable elastic connection part 91 is at least one turn. A limiting portion 92 is provided at one end of the retractable elastic connection part 91 close to the center, and a pulling portion 93 is provided at the outer end of the retractable elastic connection part 91. In this embodiment, the limiting portion 92 and the pulling portion 93 are annular, and it can be understood that the limiting portion 92 and the pulling portion 93 can also be elliptical, rectangular or other shapes, as long as the limiting portion 92 can be stuck in the retractable groove 20, and the pulling portion 93 can be connected to the rotating part of the fan blade 4.

[0063] The structure of this embodiment is simple. During the assembly process of the fan light, the limiting portion 92 and the pulling portion 93 are not easily separated from the assembled components, which greatly improves the assembly efficiency of the fan light.

[0064] In some embodiments, the limiting portion 92 is further connected to a second annular contraction elastic connection portion 94, and the other end of the second contraction elastic connection portion 94 is connected to a positioning portion 95, and the positioning portion 95 is arranged in the middle of the retractable elastic member 9. The positioning portion 95 is used to position with the central column 21 of the retractable groove 20, and the positioning portion 95 and the limiting portion 92 are used to limit the position, so that the embodiment is not easily separated from the retractable groove 20 under the influence of its own elastic force.

[0065] In some embodiments, at least one of the positioning portion 95, the limiting portion 92 and the pulling portion 93 is not in the same horizontal plane as the other two. Specifically, this embodiment may also have a shape with a part or the whole spiral rise. The positioning portion 95, the limiting portion 92 and the pulling portion 93 are not in the same plane, which can prevent the embodiment from causing interference itself.

[0066] The retractable structure includes a retractable groove 20 for connecting with the fan blade 4, the retractable elastic member 9 for the invisible fan light is arranged in the retractable groove 20, the retractable elastic member 9 is elastic, the retractable groove 20 includes a central column 21 arranged in the middle of the retractable groove 20, and a fixed column 22 arranged near the central column 21, the fixed column 22 is connected to the limiting portion 92, and the central column 21 is connected to the positioning portion 95. Such a design makes it difficult for this embodiment to be separated from the retractable groove 20 even under the influence of its own elastic force.

[0067] In some embodiments, a limiting column 23 is further included, and the limiting column 23 and the side wall of the storage groove 20 form a limiting space, the shrinking elastic connecting part 91 passes through the limiting space, and the pulling part 93 is arranged near the limiting space, and the limiting space can limit the pulling part 93 from passing through the limiting space. The design of the limiting column 23 is not only simple in structure, but also convenient for assembly.

[0068] In some embodiments, a second limiting post 24 is further included. The second limiting post 24 is disposed downstream of the first limiting post 23 along the rotation direction of the fan blade 4. The second limiting post 24 limits the rotation angle of the fan blade 4. The second limiting post 24 can prevent the fan blade 4 from rotating at an excessive angle.

[0069] In some embodiments, an anti-drop component is provided above the fixing column 22, and the anti-drop component is used to prevent the limiting portion 92 from being separated from the fixing column 22. The anti-drop component can be a bolt or a nut, as long as it can prevent the limiting portion 92 from being separated from the fixing column 22.

[0070] In some embodiments, a limiting opening 25 is provided at the bottom of the storage groove 20. The limiting opening 25 is in the shape of an arc-shaped oblong hole. The limiting opening 25 is provided between the limiting column 1 23 and the limiting column 24. The limiting opening 25 cooperates with the rotating part of the fan blade 4 to limit the rotation angle of the fan blade 4.

[0071] The retractable structure is connected to the fan blades 4, and the retractable structure enables the fan blades 4 to maintain a tendency to move in the retracted direction. The retractable structure is arranged on the mounting base 1 of the fan lamp, and the mounting base 1 is connected to the motor 2, and the motor 2 can drive the mounting base 1 to rotate. When the fan lamp rotates, the fan blades 4 open outwards under the action of centrifugal force, and when the fan stops rotating, the fan blades 4 are retracted under the elastic force of the retractable structure.

[0072] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
