Abstract
An electric pump includes a first housing, a stator assembly, and a pin. The first housing is injection-molded by using the stator assembly as an insert and fixed to the stator assembly by injection molding, and is provided with a pin hole for placing the pin. Thus, the fixation of a pump housing, the stator assembly and the pin is facilitated to be simplified.
Claims15
An electric pump, comprising a stator assembly, a first housing and a pin, wherein the stator assembly comprises a stator core, an insulating frame and a winding, the insulating frame covers at least part of a surface of the stator core, and a wire of the winding is wound around the insulating frame;
- the first housing covers at least part of the stator assembly, wherein the first housing is formed by injection molding with at least the stator assembly as a first insert or the first housing and the stator assembly are separately arranged and fixedly connected with each other, and the first housing is provided with a pin hole, in which a fixing portion of the pin is located, and the wire is fixed and electrically connected with a wire hanging portion of the pin,
- wherein the wire of the winding comprises a first section, a second section and a third section, the first section is wound around the insulating frame, the first housing is provided with a wiring hole formed by injection molding with the second section as a second insert, and a connecting section of the third section is fixed and electrically connected with the wire hanging portion of the pin,
- wherein the electric pump further comprises a conductive member, which comprises a first connecting section, a second connecting section, a second injection-molded section and a connecting portion, wherein the injection-molded section is connected with the connecting portion and the second connecting section, the first connecting section is in contact with the stator core, the first housing has a conductive hole formed with the second injection-molded section as a third insert, and an extending direction of the connecting portion is perpendicular to an axial direction of the electric pump, and wherein the first housing is provided with an accommodating groove formed by injection molding with the connecting portion as a fourth insert and has a first accommodating hole, which penetrates the first housing and is provided with an opening on a wall where the accommodating groove is formed.
