Claims20
A fan structure, comprising:
- a first fixing ring comprising a plurality of first recesses radially arranged on the first fixing ring;
- and
- a plurality of blades, one side of the blades being coupled to the first recesses, wherein the first fixing ring comprises a stamped part and a non-stamped part, and the stamped part is thinner than the non-stamped part.
A method for manufacturing a fan structure, comprising:
- placing a plurality of blades into a plurality of first recesses of a first fixing ring, wherein each of the blades and the each corresponding one of the first recesses have a gap therebetween;
- and
- stamping the first fixing ring, such that a material of the first fixing ring is squeezed and extends into the gap to fix the blades.
