At step be equipped with multiple pillars 31, and pillar 31 is arranged around the second cylinder 2, and 4 sets of circuit board on the second cylinder 2 with the
The end face of three cylinders 3 is bonded, and pillar 31 may pass through corresponding 41 fixing circuit board 4 of mounting hole on circuit board 4, avoid in bracket knot
Screw fixing circuit board is used on structure, to solve the problems, such as that conventional motors bracket and circuit board installation space are big.
In the present invention, connected between one of pillar 31 and the circumferential side wall of the second cylinder 2 by fool proof block 32, fool proof
The two sides of block 32 are parallel plane, and circuit board 4 is equipped with the fool proof notch 42 of corresponding fool proof block 32, fool proof notch 42 with it is corresponding
The mounting hole 41 of pillar 31 is connected, and guarantees the uniqueness of supporting structure and circuit board cooperation, has the advantages that fool proof.
As shown in Fig. 2, in the particular embodiment, pillar 31 is cylindrical, the axle center of pillar 31, which is equipped with, weakens stress hole,
That is circular through hole can play the role of weakening stress to a certain extent, produced when can cooperate pillar and circuit board
Stress discharged, eliminated, avoid pillar caused by stress is concentrated and deform, and pacify convenient for pillar and circuit board
Dress；For the ease of the processing in hole, entire pillar can also be run through by weakening stress hole.And pillar passes through across the mounting hole of circuit board
Riveting cooperates fixing circuit board, avoids using screw, wherein the outer diameter of pillar is D, diameter of bore d, at circuit board mounting hole
With a thickness of a, the height of pillar is b, and size is met the requirements: k(D/2-d/2) >=b-a >=D/2-d/2,1.3 >=k of proportionality coefficient
