The oblique direction of the second support rib is opposite to the oblique direction of the first support rib, so that the upper plate, the lower plate, the first support rib and the second support rib form a triangular or trapezoidal cross section.

[0012] As described above, in a novel fan blade structure, the supporting structure includes a third supporting rib, which is disposed within the fan blade cavity along the length of the fan blade body. A plurality of the third supporting ribs are arranged along the width of the fan blade body. One end of the third supporting rib is perpendicularly connected to the lower plate, and the other end extends to be perpendicularly connected to the upper plate.

[0013] As described above, in a novel fan blade structure, the support structure includes:

[0014] The first guide rib extends along the upper plate towards the fan blade cavity, and multiple first guide ribs are arranged along the width direction of the fan blade body.

[0015] The second guide rib extends along the lower plate towards the fan blade cavity. Multiple second guide ribs are arranged along the width of the fan blade body and correspond to the first guide ribs respectively. An installation cavity is formed between two adjacent first guide ribs and two second guide ribs.

[0016] The support block is movably inserted into the mounting cavity along the length of the fan blade, and the outer wall of the support block is in contact with the upper plate, the lower plate, the first guide rib, and the second guide rib.

[0017] As described above, in a novel fan blade structure, a support block cavity is provided inside the support block.

[0018] As described above, in a novel fan blade structure, the first guide rib and the second guide rib are arranged along the length direction of the fan blade body.

[0019] As described above, in a novel fan blade structure, the upper plate, lower plate, first connecting part, second connecting part, first guide rib, and second guide rib are integrally formed.

[0020] As described above, in a novel fan blade structure, the cross-section of the fan blade body is arc-shaped.

[0021] Compared with the prior art, the present invention has the following advantages:

[0034] A specific embodiment, as shown in the figure, discloses a novel fan blade structure comprising: a fan blade body 1, which includes an upper plate portion 11, a lower plate portion 12 disposed opposite to the upper plate portion 11, and a first connecting portion 13 and a second connecting portion 14 respectively connecting the two ends of the upper plate portion 11 and the lower plate portion 12, wherein the upper plate portion 11, the lower plate portion 12, the first connecting portion 13, and the second connecting portion 14 form a fan blade cavity 2; and a support structure 3 disposed within the fan blade cavity 2 for supporting the upper plate portion 11 and the lower plate portion 12. The fan blade cavity within the structure reduces material usage, lowers production costs, and makes the fan blade lighter, facilitating transportation and installation. Furthermore, the support structure within the fan blade cavity ensures the overall structural strength of the fan blade body.

[0035] Specific embodiment 1, such as Figure 1 As shown, the upper plate 11, lower plate 12, first connecting part 13, second connecting part 14, and support structure 3 are integrally molded. The use of integral injection molding makes the fan blades lighter, improves production efficiency, and reduces overall costs.

[0036] Specifically, the support structure 3 includes: a first support rib 31, which is disposed in the fan blade cavity 2 along the length direction of the fan blade body 1, and a plurality of first support ribs 31 are arranged at intervals along the width direction of the fan blade body 1. One end of the first support rib 31 is connected to the lower plate portion 12, and the other end extends obliquely to connect with the upper plate portion 11; a second support rib 32, which is disposed in the fan blade cavity 2 along the length direction of the fan blade body 1, and a plurality of second support ribs 32 are arranged at intervals along the width direction of the fan blade body 1. One end of the second support rib 32 is connected to the lower plate portion 12, and the other end extends obliquely to connect with the upper plate portion 11. The oblique direction of the second support rib 32 is opposite to the oblique direction of the first support rib 31, so that the upper plate portion 11, the lower plate portion 12, the first support rib 31 and the second support rib 32 form a triangular or trapezoidal cross section, which has a good support effect and high overall structural strength.

[0037] More specifically, the cross-section of the fan blade 1 is arc-shaped.

[0038] Specific embodiment 2 differs from specific embodiment 1 in that, as Figure 2 As shown, the support structure 3 includes a third support rib 33, which is disposed in the fan blade cavity 2 along the length direction of the fan blade body 1. A plurality of third support ribs 33 are arranged along the width direction of the fan blade body 1. One end of the third support rib 33 is perpendicularly connected to the lower plate 12, and the other end extends to be perpendicularly connected to the upper plate 11.

[0039] Specific embodiment 3, such as Figure 3-5As shown, the support structure 3 includes: a first guide rib 34 extending along the upper plate portion 11 towards the fan blade cavity 2, with multiple first guide ribs 34 arranged along the width direction of the fan blade body 1; a second guide rib 35 extending along the lower plate portion 12 towards the fan blade cavity 2, with multiple second guide ribs 35 arranged along the width direction of the fan blade body 1 and corresponding to the first guide ribs 34 respectively, with an installation cavity 4 formed between two adjacent first guide ribs 34 and two adjacent second guide ribs 35; and a support block 36 movably inserted into the installation cavity 4 along the length direction of the fan blade body 1, with the outer wall of the support block 36 abutting against the upper plate portion 11, the lower plate portion 12, the first guide ribs 34, and the second guide ribs 35. The first guide ribs 34 and the second guide ribs 35 provide limiting and guiding, facilitating installation. The modular design reduces manufacturing costs, facilitates maintenance and replacement, and allows adjustment of the overall fan blade weight by replacing support blocks 36 of different weights, resulting in greater versatility.

[0040] Specifically, the support block 36 has a support block cavity 361. This further reduces the amount of materials used in production, lowers production costs, and makes the block lighter, facilitating transportation and installation.

[0041] More specifically, the first guide rib 34 and the second guide rib 35 are arranged along the length direction of the fan blade body 1 to improve the overall structural strength.

[0042] Furthermore, the upper plate 11, lower plate 12, first connecting portion 13, second connecting portion 14, first guide rib 34, and second guide rib 35 are integrally formed, thereby improving production efficiency.

[0043] The above description is one embodiment provided in conjunction with specific content, and does not imply that the specific implementation of this utility model is limited to these descriptions. Furthermore, due to different industry naming conventions, it is not limited to the above names or English names.
