Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is an exploded view of the structure of the present invention;

fig. 2 is a schematic sectional view of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 2, a stator assembly injection molding integrated motor assembly and a water pump using the same, wherein the motor assembly includes a motor housing 1, a stator assembly 12 connected by an injection molding integrated process is provided in the motor housing 1, a pump shaft 10 is provided in the middle of the stator assembly 12, and open type slots 1a are symmetrically distributed on two sides of the exterior of the motor housing 1. Damping pad 8 is blocked in open type draw-in groove 1a, damping pad 8 is hollow structure and has inserted bush 9. The damping pad 8 is made of elastic rubber materials and is of an I-shaped revolving body structure, the diameter of the middle of the damping pad 8 is matched with that of the open type clamping groove 1a, the upper end and the lower end of the damping pad are attached to the end face of the open type clamping groove 1a, and through the structural design, the damping pad 8 can be tightly clamped in the open type clamping groove 1 a.

The water pump using the motor assembly comprises a pump shell 2, the motor assembly and a motor rear cover 3 which are sequentially connected through a screw 7, wherein an impeller rotor assembly 4 matched with a stator assembly 12 is arranged at the front end of the motor assembly, a controller assembly 5 is arranged at the rear end of the motor assembly, and a sealing ring 6 is arranged between the motor assembly and the motor rear cover 3.
