DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, an embodiment of the present application proposes a fan blade, comprising: a base 1, at least two folding sheets 2 and at least two stretching sheets 3, wherein the folding sheets 2 and the stretching sheets 3 are arranged in sequence along the circumference of the base 1; a first through hole 6 is provided at the center of the base 1, and a second through hole 7 is provided at the free end of the folding sheet 2; the length of the first side 4 of the stretching sheet 3 is longer than the length of the second side 5 of the stretching sheet 3.

[0032] In this embodiment, the number of folding sheets 2 and stretching sheets 3 is set to 5 sheets respectively. Of course, those skilled in the art can adaptively increase or decrease the number of folding sheets 2 or stretching sheets 3, such as setting the number of folding sheets 2 and stretching sheets 3 to 2, 3, 4, 6, 7 and 8 sheets respectively. The folding sheets 2 and stretching sheets 3 are sequentially arranged in a circumferential direction of the base 1, specifically, the connecting end of the folding sheet 2 and the connecting end of the stretching sheet 3 are connected to the base 1, a first perforation 6 is arranged at the center of the base 1, and a second perforation 7 is arranged at the free end of the folding sheet 2. The folding sheet 2 is bent so that the first perforation 6 corresponds to the second perforation 7, and an air duct 19 is formed between the base 1 and the folding sheet 2. In addition, the length of the first side 4 of the stretching sheet 3 is longer than the length of the second side 5 of the stretching sheet 3. Since the lengths of the two sides of the stretching sheet 3 are different, when the folding sheet 2 is folded, the stretching sheet 3 forms an angle with the horizontal plane. The fan blade proposed in this embodiment can be applied to both windmills and bamboo helicopters through the air duct 19 between the base 1 and the folding piece 2, as well as the angle formed by the extending piece 3 and the horizontal plane, thereby providing users with higher playability.

[0033] Optionally, the length of the first side 4 of the stretch sheet 3 is longer than the length of the second side 5 of the stretch sheet 3. Specifically, the end point of the first side 4 is connected to the end point of the second side 5 to form a connecting line 20. The angle 21 formed by the connecting line 20 and the second side 5 is within a range of less than or equal to 180° and greater than 90°. Figure 4 and Figure 5 As shown, when the angle 21 is less than 180° and greater than 90°, after the folding piece 2 is folded, the stretching piece 3 forms an angle with the horizontal plane, so that the fan blades can rotate; when the angle 21 is equal to 180°, after the folding piece 2 is folded, the stretching piece 3 is bent along the connecting line 20, so that the stretching piece 3 forms an angle with the horizontal plane, ensuring that the fan blades can rotate.

[0034] Optionally, the base 1, the folding sheet 2 and the stretching sheet 3 are integrally arranged, which is convenient for mass production and user assembly. A three-dimensional fan blade can be formed by simply connecting and fixing the first perforation 6 and the second perforation 7.

[0035] Optionally, the folding sheet 2 is provided with a window 8; and / or the extending sheet 3 is provided with a through hole 9. Compared with the closed blades in the prior art, by providing the window 8 and / or the through hole 9, an air duct 19 can be added, so that the fan blade is not affected by the wind direction, and can rotate regardless of whether the wind direction blows on the windward side or the non-windward side of the blade.

[0036] In this embodiment, a window 8 is provided on the folding sheet 2 and a through hole 9 is provided on the stretching sheet 3. Of course, those skilled in the art are motivated to only provide the window 8 on the folding sheet 2 or only provide the through hole 9 on the stretching sheet 3.

[0037] Specifically, when the folding sheet 2 is provided with a window 8 , the folding sheet 2 is also provided with a window sash 10 , and one end of the window sash 10 is connected to the folding sheet 2 .

[0038] In this embodiment, a window sash 10 is provided on the folding sheet 2, and the window sash 10 is arranged corresponding to the window 8 so that the wind can form a certain angle. Specifically, an unclosed cut can be provided on the folding sheet 2, and the cut part of the folding sheet 2 is tilted relative to the folding sheet to form the window sash 10, and the open part forms the window 8.

[0039] Optionally, the folding sheet 2 is further provided with a free sheet 11 to increase the flow direction of wind, enhance the interest of the fan blades, and improve the user experience.

[0040] In this embodiment, the free piece 11 is formed by cutting the side of the folding piece 2. When the folding piece 2 is folded and the second perforation 7 is connected to the first perforation 6, the free end of the free piece 11 protrudes from the folding piece 2, increasing the flow direction of the wind.

[0041] Optionally, the free pieces 11 are symmetrically arranged on both sides of the folding piece 2 to ensure force balance.

[0042] In this embodiment, the shape of the extension piece 3 is set to the shape of petals, and the shape of the free piece 11 is set to the shape of a pistil. When the folding piece 2 is folded and the first perforation 6 is connected to the second perforation 7, the fan blade as a whole forms a flower shape.

[0043] Example 2

[0044] like Figure 6 and Figure 7 As shown, this embodiment proposes a windmill, including the fan blades mentioned above, and also includes: a rivet 12 and a connecting component, the rivet 12 connects the first through-hole 6 and the second through-hole 7, and the connecting component is connected to the rivet 12.

[0045] In this embodiment, the connection assembly includes: a first connection member 13, a bending head 14, and a second connection member 15. The bending head 14 connects the first connection member 13 and the second connection member 15. The rivet 12 connects the first through hole 6 and the second through hole 7, so that the fan blade forms a folded shape. The second connection member 15 connects the rivet 12 and the bending head 14, so that the folded fan blade is connected to the first connection member 13 to form a windmill.

[0046] Example 3

[0047] like Figure 8 and Fig. 9 As shown, this embodiment proposes a bamboo dragonfly, including the fan blades mentioned above, and also includes: a plug 16 and a connecting rod 17, and the connecting rod 17 connects the first through hole 6, the second through hole 7 and the plug 16.

[0048] In this embodiment, a protruding structure 18 is provided on the connecting rod 17, and the connecting rod 17 passes through the first through hole 6 and the second through hole 7 and is connected to the plug 16, so that the fan blades form a stable folded shape between the protruding structure 18 and the plug 16 to obtain a bamboo dragonfly.
