Abstract

The invention discloses a micro hydraulic suspension mechanical pump structure and an assembling method thereof. The hydraulic suspension micro pump includes a volute, an upper end cap, a positioning sheet, an impeller, a hollow cup motor, a waterproof cover, and a rotor. The hollow cup motor includes a motor casing, a motor bottom cap, a magnet rotor, a coil, and an iron core. The waterproof cover is in a separated state from the motor, and a lower part has a positioning boss to implement radial cooperation with a recess at a corresponding position of the motor. At the same time, there is the sheet between the recess and the boss to implement axial positioning of the waterproof cover.
