Technical scheme of the present invention is: a kind of electric motor end cap, comprise the end cap body, described end cap body comprises flange portion and is located at the tubular protuberance of flange portion bottom, described end cap body is provided with a brush plate and two brush rooms, described end cap body and brush plate, brush room are integrated the injection mo(u)lding structure, and wherein, brush plate is located at flange portion inner chamber bottom surface, the brush room is located on the flange portion bottom outer surface, and described two brush rooms arrange around the even interval of tubular protuberance outer circumferential sides; Described tubular protuberance intracavity bottom is bearing chamber, and described bearing chamber inwall is provided with at least three along the axially extended cuboid boss of bearing chamber.
Preferably, described brush within doors side is connected with tubular protuberance outer circumference surface, and described brush room is respectively equipped with the strip groove of longitudinal extension up and down on four sidewalls.The left and right sides, described brush room wall is provided with longitudinal extension and the through slot of lateral direction penetrating.Brush can be conveniently installed, be changed in the brush room, and brush within doors chamber is " ten " font substantially, in order to brush is played positioning action.
Preferably, described brush roof section is provided with L shaped lead-in wire fixed leg.The terminal side of described lead-in wire fixed leg is provided with one and picks up the ears.The lead-in wire fixed leg can play fixation to the lead-in wire of brush.
Preferably, described flange portion oral area inner circumferential side is provided with the annular flange flange that a circle protrudes from flange portion oral area end face, and described annular flange flange outer circumference surface is provided with at least three stairstepping boss.
Preferably, described stairstepping boss is provided with two-stage, and the two-stage boss is cuboid, wherein the long-pending height that is first order boss of the height of second level boss and countertop and countertop long-pending 1/5th to 1/3rd.
Preferably, the corresponding described stairstepping boss of described annular flange flange inner peripheral surface is provided with convex tendon.Improve assembling intensity.
Preferably, described convex tendon cross section is isosceles triangle, isosceles trapezoid or protuberance circular arc.
Preferably, described cuboid boss and stairstepping boss are provided with eight.
The present invention, both provided cost savings end cap body, brush room by injection moulding integrated molding in brush carrier, simultaneously in installation, more convenient when changing brush.Bearing chamber arranges a plurality of cuboid boss, and bearing chamber and bearing fit face are a plurality of points like this, but not the whole face of cylinder, has improved the degree of assembled of bearing and end cap.Same reason, the stairstepping boss of end cap body connection seam position has then improved the degree of assembled of end cap and motor, and comprehensive says, and the operating efficiency the when end cap of this structure has improved the mounted motor end cap has on the whole also reduced cost.
