[0030] Reference Figures 1 to 4 According to this utility model, a retractable ceiling fan light with visible fan blades 200 includes a blade disk 100, multiple fan blades 200, and a lighting assembly. The blade disk 100 is connected to a driving structure to drive it to rotate. The fan blades 200 are rotatably connected to the blade disk 100. The multiple fan blades 200 are evenly distributed along the circumference of the blade disk 100 and can unfold as the blade disk 100 rotates. A tightening structure is provided between the fan blades 200 and the blade disk 100, which can drive the fan blades 200 to always face the opposite direction to the unfolding direction. The fan blades 200 include an inner edge 201, an outer edge 202, and a downward curved surface 203. The inner edge 201 and the outer edge 202 are connected by the downward curved surface 203. The horizontal height of the outer edge 202 is lower than the horizontal height of the impeller 100. When multiple fan blades 200 are closed, they can form an arc-shaped cover. The lighting assembly includes a lamp holder and a first light source 320. The lamp holder is fixedly installed on the bottom of the impeller 100, and the first light source 320 is installed on the outer side of the lamp holder and faces the arc-shaped cover.

[0031] It is understood that the retractable ceiling fan light with visible blades 200 provided in this embodiment of the present invention achieves the function of automatically unfolding and retracting the blades 200 by setting a drive structure and a tightening structure, reducing the application of traditional complex mechanical structures, lowering production costs, and improving the reliability and durability of the equipment. The arc-shaped cover formed by the retracted blades 200 focuses and reflects the light emitted by the first light source 320, thus enabling it to be used as a lampshade in normal operation, increasing functionality and practicality, simplifying the structure, and enhancing aesthetics. Furthermore, the overall arc design of the blades 200 enhances airflow during rotation, resulting in a larger area of ​​air agitation and stronger wind, further improving practicality.

[0032] Furthermore, refer to Figure 4 According to some embodiments of the present invention, the outer side of the lamp holder is provided with a mounting groove 311, and the first light source 320 is an LED light strip, which is fixedly installed in the mounting groove 311.

[0033] Understandably, by using LED light strips as the first light source 320 in a ring, the light distribution can be made more uniform, thus improving practicality.

[0034] Furthermore, refer to Figure 4 According to some embodiments of the present invention, the lamp assembly further includes a second light source 330, the bottom of the lamp holder is provided with a downward-facing mounting cavity 312, the lamp holder is connected to a light-transmitting cover 340 with a closed opening, and the second light source 330 is installed in the mounting cavity 312 and faces the light-transmitting cover 340.

[0035] It is understandable that when the fan blades 200 are in the rotating and unfolded state, the second light source 330 can be used as the main light source for indoor lighting. When the fan blades 200 are in the retracted state, the second light source 330 can be used in conjunction with the first light source 320 for indoor lighting, thereby improving the lighting effect and making it suitable for different environmental needs, thus improving practicality.

[0036] Furthermore, refer to Figure 1 According to some embodiments of the present invention, the impeller 100 is provided with a plurality of rotating arms 110 evenly spaced along its outer periphery. The rotating arms 110 correspond one-to-one with the fan blades 200. One end of the fan blades 200 is rotatably connected to the end of the rotating arm 110, thereby simplifying the structure, facilitating installation and maintenance, and increasing the stability of the fan blades 200 during operation.

[0037] Furthermore, refer to Figures 1 to 3 According to some embodiments of the present invention, a support arm 210 is fixedly connected to the inner side of the fan blade 200 near the inner edge 201. The support arm 210 extends along the inner edge 201. A rotating shaft 211 is provided on the upper end face of one end of the support arm 210. A rotating part 111 is provided at the end of the rotating arm 110. The rotating shaft 211 is located inside the rotating part 111 and is rotatably connected to the rotating part 111.

[0038] Understandably, the connection between the rotating part 111 and the rotating shaft 211 ensures the flexibility and stability of the fan blade 200's rotation, reduces mechanical wear, extends service life, and has a simple structure that is easy to install and maintain.

[0039] Furthermore, refer to Figure 3 and Figure 4 According to some embodiments of the present invention, the tightening structure includes a torsion spring 220, which is located inside the rotating part 111 and fitted onto the rotating shaft 211. One end of the torsion spring 220 is fixedly connected to the rotating part 111, and the other end of the torsion spring 220 is fixedly connected to the support arm 210.

[0040] Understandably, by utilizing the elasticity of the torsion spring 220, the fan blades 200 can be effectively kept in their retracted state when not in operation. At the same time, after the blade disk 100 stops rotating, the fan blades 200 can be quickly and effectively retracted, thus enhancing the reliability of the system.

[0041] Furthermore, refer to Figure 1 and Figure 2According to some embodiments of the present invention, a limiting part 112 is provided on the outer side of the rotating part 111, and a first limiting member 212 and a second limiting member 213 are respectively provided on both sides of the rotating part 111. When the multiple fan blades 200 are closed, the first limiting member 212 can abut against the limiting part 112, and when the multiple fan blades 200 are unfolded, the second limiting member 213 can abut against the rotating arm 110.

[0042] Understandably, the coordinated design of the limiting part 112, the first limiting member 212, and the second limiting member 213 ensures the positioning accuracy of the fan blade 200 in both the unfolded and retracted states, prevents damage caused by excessive rotation, and enhances the safety of the product.

[0043] Furthermore, refer to Figure 1 According to some embodiments of the present invention, a first arc line 204 is provided between the inner end of the inner edge 201 and the inner end of the outer edge 202, and a second arc line 205 is provided between the outer end of the inner edge 201 and the outer end of the outer edge 202. The shape of the first arc line 204 is adapted to the shape of the second arc line 205 of the other adjacent fan blade 200.

[0044] Understandably, the design of the first arc 204 and the second arc 205 allows the adjacent fan blades 200 to fit together better when retracted, forming an aesthetically pleasing arc cover. At the same time, the arc design enhances airflow during rotation, resulting in a larger area of ​​air agitation, stronger wind, and improved practicality.

[0045] It should be noted that in the above embodiments, the inner end of the inner edge 201 refers to the end of the inner edge 201 that is close to the blade disk 100 after the fan blade 200 is unfolded, and the outer end of the inner edge 201 refers to the end of the inner edge 201 that is far away from the blade disk 100 after the fan blade 200 is unfolded. The inner end and outer end of the outer edge 202 can be obtained in the same way, and will not be described again here.

[0046] Furthermore, refer to Figure 1 According to some embodiments of the present invention, there is a gap between the first arc line 204 and the second arc line 205 of another adjacent fan blade 200.

[0047] It is understandable that by having a gap between two adjacent fan blades 200, damage caused by collision between the two fan blades 200 when they are closed can be effectively avoided.

[0048] Furthermore, refer to Figure 3 and Figure 4According to some embodiments of the present invention, the drive structure includes a drive motor 120 and a suspension rod 130. The drive motor 120 is fixedly installed at the bottom center of the impeller 100, and the lamp holder is fixedly installed at the bottom of the drive motor 120. The middle part of the impeller 100 is hollowed out so that the output shaft of the drive motor 120 faces upward and is fixedly connected to the bottom end of the suspension rod 130, thereby driving the impeller 100 to rotate around the suspension rod 130 as the axis.

[0049] Specifically, in this embodiment of the invention, after the drive motor 120 starts, it drives the impeller 100 to rotate. After the impeller 100 rotates, it generates centrifugal force, which causes the fan blades 200 to gradually overcome the elastic force of the torsion spring 220 and be thrown out, so that multiple fan blades 200 unfold at a certain angle, thus starting to work. When the drive motor 120 is turned off, the rotation speed of the impeller 100 gradually slows down. At the same time, under the elastic force of the torsion spring 220, the fan blades 200 move in the opposite direction to the unfolding direction of the fan blades 200, and then gradually retract. The retracted fan blades 200 form an arc-shaped cover. At this time, the arc-shaped cover can be used as a lampshade when the first light source 320 is turned on.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
