Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Refer to fig. 1 to 3. The fan blade assembly of the motor comprises a fan blade 1 and a magnetic ring 2, wherein the fan blade 1 comprises a plurality of blades 11, a mounting column 12 is arranged in the middle of the fan blade 1, the blades 11 are uniformly distributed on the periphery of the mounting column 12, mounting holes 13 are formed in the mounting column 12, the magnetic ring 2 is sleeved on the outer side of the mounting column 12, and the mounting column 12 and the fan blade 1 are of an integral injection molding structure. In the practical use process, the fan blade 1 further comprises a panel 16, the blades 11 are arranged on the panel 16, and the adjacent blades 11 and the panel 16 form an air duct, so that heat can be dissipated in time. Wherein, the blade 11 and the panel 16 are of an integrated structure.
The middle of the fan blade 1 is provided with the mounting column 12, the magnetic ring 2 can be directly sleeved on the mounting column 12, namely the magnetic ring 2 is directly mounted on the fan blade 1, zero distance between the magnetic ring 2 and the fan blade 1 is achieved, the axial length of the whole fan blade assembly is greatly shortened, the whole occupied space is small, meanwhile, the assembly steps are reduced, the assembly time is saved, and the assembly efficiency is improved. Meanwhile, the installation of the motor rotating shaft can be facilitated by arranging the installation hole 13.
In actual use, in order to ensure the heat dissipation efficiency of the fan blade 1, the outer edge of the blade 11 is flush with the outer edge of the panel 16.
The outside of erection column 12 is equipped with card strip 14, and the inner wall of magnetic ring 2 is equipped with draw-in groove 21, and draw-in groove 21 cooperatees with card strip 14. The clamping strip 14 is inserted into the clamping groove 21, so that the magnetic ring 2 is firmly matched with the mounting column 12. Wherein, card strip 14 and draw-in groove 21 are two, improve the stability of complex.
