Protruding block there are four fixed, 16 protruding blocks are spaced apart with eight fan blade mounting holes, and two fan blades are far from pawl
One end of part group is mounted on fixing sleeve, and two fixing sleeves open up that there are four fixed in an end section of two fan blades
Set groove and four fixing sleeve mounting holes, eight fixing sleeve grooves are spaced apart with eight fixing sleeve mounting holes.
Preferably, the area of section of the bluff piece group groove is equal with the area of section of fixing sleeve groove.
Preferably, the protruding block respectively with bluff piece group groove and fixing sleeve groove match.
Preferably, the bluff piece group includes two staggered fasteners.
Preferably, the bolt is an integral structure with bluff piece group.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) of the invention, fan blade is fixedly connected with bluff piece group by screw bolt and nut, and bolt and bluff piece group are integral type
Structure so that the surface of bluff piece group is smooth, and to improve flatness when fan blade installation, and the connection type of screw bolt and nut is just
In installing and dismounting and fan blade is replaced, can be energy saving and makes fan blade uniform rotation, to reduce noise.
(2) of the invention, it is provided with multiple protruding blocks and groove, is distinguished two end faces of fan blade by protruding block and groove
It is connect with bluff piece group and fixing sleeve, generates relative displacement between bluff piece group and fixing sleeve when being conducive to prevent fan blade from rotating, carry
The fastness that high fan blade is connect with bluff piece group.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of fixed structure of New energy automobile motor fan blade,
Including main shaft 1, the middle position of main shaft 1 is fixed with bluff piece group 4, and is respectively provided on the section at 4 both ends of bluff piece group there are four pawl
Part group groove 8 and four bolts 5, bluff piece group 4 are responsible for fixed core, and eight bolts 5 divide with eight intervals of bluff piece group groove 8
