Its blade assembly includes a blade, a blade holder, and an elastic element. During use, the elastic element causes the blade to rotate and unfold or fold from the blade holder, as shown in CN202323462688.9. Although it can meet the general usage needs, the elastic element of each blade is set separately. It cannot guarantee the synchronous operation of each blade, nor can it effectively achieve the synchronous folding of the blades, which affects the stability and reliability of use and limits its applicability. Summary of the Invention

[0010] A further preferred embodiment is that the bottom surface of the fan disc is provided with two limiting protrusions;

[0011] A limit block is provided on the side wall of the cylinder;

[0012] The cylinder drives the fan blades to rotate, and the limiting block rotates between two limiting protrusions to limit the unfolding or folding of the fan blades.

[0013] A further preferred embodiment is that the annular turntable is positioned between the cylinder and the fan motor spindle;

[0014] A spring clip is fixed to the bottom surface of the fan disc;

[0015] The edge of the annular turntable is fixed with a protruding plate;

[0016] The spring plate is located on the outside of the circular turntable, and the outer end of the reset spring is fixed on the spring plate and the inner end of the reset spring is fixed on the convex plate.

[0017] A further preferred embodiment is that: the end of the arc-shaped guide groove is provided with a snap-in relief groove, the width of the snap-in relief groove is matched with the width of the horizontal part of the T-shaped block, and the width of the arc-shaped guide groove is matched with the width of the vertical part of the T-shaped block;

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0032] See Figures 1 to 5 As shown, a fan light with a folding blade structure includes a fan light bracket 1, a hanging rod 2 connected to the fan light bracket, a fan structure 3 and a lighting structure 4 disposed at the bottom of the hanging rod. In this embodiment, the fan light bracket and hanging rod are conventional structures of the prior art, so they are not described in detail. The lighting structure includes a mounting plate 41, a light source plate 42 and a lamp panel 43. During assembly, the mounting plate is fixed to the bottom end of the support rod at the center of the fan motor, and the light source plate and the lamp panel are located on the mounting plate.

[0033] In this embodiment, the fan structure includes a fan motor 31, a fan disk 32 fixed on the fan motor spindle, and several cylinders 33 rotatably connected to the edge of the fan disk. A fan blade 34 is fixed to the center of each cylinder by bolts. Furthermore, several arc-shaped guide grooves 35 are provided on the surface of the fan disk. A circular turntable 36 is provided on the bottom surface of the fan disk, and a T-shaped locking block 37 for engaging the arc-shaped guide grooves is fixed on the circular turntable. The fan motor, fan blades, and fan disk are all conventional structures in the prior art, and are simply applied. The diameter of the cylinders can be set as needed. They are mainly used to connect the fan blades and the transmission plate. The cylinders can be rotated by the transmission plate to open or fold the fan blades.

[0034] In this embodiment, the annular turntable is provided with a connecting shaft 5, and the bottom edge of the cylinder is provided with a convex shaft 6. A transmission plate 7 is provided between the convex shaft and the connecting shaft. A return spring 8 is provided between the edge of the annular turntable and the bottom surface of the fan disc. In use, the annular turntable drives the fan blades to unfold through the transmission plate, and the fan blades fold under the action of the return spring. When the fan motor rotates, it drives the fan disc to rotate. Since the annular turntable is in the arc-shaped guide groove, it will shift relative to the fan disc and drive the cylinder to rotate through the transmission plate, causing the fan blades to open. When the fan motor stops, the fan blades return to their original position and fold under the action of the return spring.

[0035] In this embodiment, the bottom surface of the fan disc is provided with two limiting protrusions 9; the side wall of the cylinder is provided with a limiting stop 10; during use, the cylinder drives the fan blades to rotate, and the limiting stop rotates between the two limiting protrusions to limit the unfolding or folding of the fan blades. By using the limiting stop in conjunction with the limiting protrusions, the unfolding or folding range of the fan blades can be limited, preventing excessive rotation of the fan blades and improving the stability and reliability of use.

[0036] In this embodiment, the annular turntable is positioned between the cylinder and the fan motor spindle; a spring retainer plate 11 is fixed to the bottom surface of the fan disc; a protruding plate 12 is fixed to the edge of the annular turntable; the spring retainer plate is located on the outer side of the annular turntable, and the outer end of the return spring is fixed to the spring retainer plate while the inner end of the return spring is fixed to the protruding plate. This ensures the stability and reliability of the structural connection.

[0037] In this embodiment, the end of the arc-shaped guide groove is provided with a locking groove 13. The width of the locking groove matches the width of the horizontal portion of the T-shaped block, and the width of the arc-shaped guide groove matches the width of the vertical portion of the T-shaped block. The T-shaped block engages with the locking groove and rotates to lock itself within the arc-shaped guide groove. This improves the ease of assembly and disassembly of the annular turntable, and the number of locking grooves can be three or four, with the length of the locking grooves adjustable as needed.

[0038] In practical applications, a DC driver 14 is installed on the fan light bracket; the DC driver is connected to the fan motor and the light source board. The DC driver is a conventional structure found in existing technology, and its application is simply simplified.

[0039] This invention has several advantages: The structure is rationally designed, with several arc-shaped guide grooves on the fan disc surface; a circular turntable is located on the bottom of the fan disc, with a T-shaped locking block fixed on it; a transmission plate is positioned between the convex shaft and the connecting shaft; and a return spring is located on the edge of the circular turntable and the bottom of the fan disc. This return spring rotates with the fan disc as it rotates, synchronously driving the fan blades to open via the transmission plate, ensuring the smooth and effective use of the fan blades. After the fan motor stops, the return spring causes the fan blades to fold back to their original position, improving fan performance. Furthermore, it is energy-efficient, low-noise, and highly adaptable.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
