[0048] Example 2

[0049] Based on Example 1, this example provides a partial structural diagram of the UAV blade structure when it is installed. Figure 3 and Figure 4 shown.

[0050] Specifically, Figure 3 The figure shows a cross-sectional view of the base assembly in the UAV blade structure, wherein the driving member adopts a multi-layer structure, and the uppermost layer for installing the base 21 belongs to the output layer, which is used to output a control signal to control the rotation of the blade.

[0052] Example 3

[0053] Based on Example 1 and Example 2, this embodiment provides a method for disassembling and assembling a drone blade structure.

[0054] When installing the UAV blade structure, first use the four positioning holes 321 on the positioning pin shaft 32 to match the positioning pin 23 in the base assembly 20. The positioning pin shaft 32 passes through the pin hole 212 on the base 21 to squeeze the surrounding positioning pins 23 in all directions. At the same time, the elastic force of the elastic device 24 is used to ensure that the positioning pin 23 can automatically rebound after being installed in place and tightly fit into the positioning hole 321 of the positioning pin shaft 32. This process not only realizes the stable connection between the blade body 10 and the base assembly 20, but also improves the installation efficiency of the UAV blade structure.

[0055] When the drone blade structure is disassembled, the positioning pin shaft 32 is designed with an unlocking hole 322. The unlocking pin 40 is inserted into the unlocking hole 322 and a certain force is applied to squeeze the positioning pin 23 around again to make it disengage from the positioning hole 321, thereby releasing the base assembly 20 from the cover assembly 30. The operation is simple and quick, and no complicated tools or cumbersome steps are required. The blade body 10 can be easily separated from the base assembly 20, which greatly facilitates the replacement and maintenance of the blade. The drone blades can be quickly and stably installed and disassembled, and the maintenance convenience, safety and stability of the drone during use are enhanced.

[0056] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Any equivalent replacement and improvement based on the technical essence of the present invention shall be included in the protection scope of the present invention. At the same time, the embodiments of the present invention can be used in combination with each other to produce more different implementation schemes.
