Further, described stator is arranged on the inside of described integral housing by the way of press-fiting, and described electronic control unit is between the blind end of described stator and described integral housing.
Further, described water-resisting piece being formed with rotor supports cavity, this rotor supports cavity is at least partially inserted into the inside of described stator, and described rotor portion or the rotor supports inside cavity that is entirely located on described water-resisting piece.
Further, described internal rotor is formed with cavity structure, described impeller is formed or is provided with impeller support shaft, and this impeller support shaft is fixedly mounted in the cavity structure of described internal rotor.
Further, this electronic water pump also includes impeller gripper shoe, and this impeller gripper shoe is between described impeller and rotor, and this impeller gripper shoe is fixed with described water-resisting piece and is connected.
Further, this electronic water pump also includes bearing, and this bearing holder (housing, cover) is contained in described impeller support shaft.
Further, described impeller gripper shoe being formed with bearing mounting hole, described bearing is arranged in this bearing mounting hole.
Further, described water-resisting piece is between described water pump end cap and integral housing, and fixing between described water pump end cap, water-resisting piece and integral housing is connected.
Compared with prior art, the structure design unique owing to have employed the integral housing with electric linkage function, independent water-resisting piece and impeller gripper shoe etc., the electronic water pump that this utility model provides has low cost, the advantage that stability is high.
