AI Technical Summary
Traditional stator sealing structures are susceptible to the lifespan of the sealing rings, are complex to assemble, prone to leakage, and costly.
The stator assembly is sealed to the housing, waterproof chamber and shaft by an integral plastic coating method. The inner plastic coating layer is stepped and has a uniform wall thickness, while the outer plastic coating layer forms a uniform wall thickness on the basis of the inner layer, which reduces the requirements for hot runners and temperature.
It improves sealing performance, reduces the risk of leakage, simplifies the processing, and lowers costs.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of motor stator seal, in particular to a structure of uniform wall thickness of stator integrated plastic package. BACKGROUND
[0002] The stator is an important component of the motor, in the traditional stator design, the positioning needs with the shell and waterproof chamber etc. through the sealing ring to form a sealed area, to ensure that the stator is not affected by the water vapor in the air and the cooling liquid leakage inside the electronic water pump. Then rely on sealing ring to assemble the sealing process of positioning assembly is complex, not easy to assemble, and is affected by the service life of sealing ring, easy to leak, so need a kind of processing simple, low cost stator sealing mechanism. SUMMARY
[0003] To solve the above technical problems, the utility model provides a kind of structure of uniform wall thickness of stator integrated plastic package, the sealing effect of stator assembly is good, not easy to leak, it is convenient to process, and practicality is high.
[0004] The structure of uniform wall thickness of stator integrated plastic package of the utility model, including stator assembly;The outer side wall of the stator assembly is provided with a plastic layer, and the stator assembly is located in the plastic layer;When assembling, the shell, waterproof chamber, shaft and stator on the stator assembly are sealed by the whole plastic package, the sealing effect is good, not easy to leak, it is convenient to process, low in cost, and practicality cover.
[0005] Preferably, the plastic layer includes an inner plastic layer and an outer plastic layer, the inner plastic layer contacts the stator assembly, the outer plastic layer contacts the inner plastic layer, and the outer plastic layer is located outside the inner plastic layer;By setting two plastic layers on the outside of the stator assembly, the stator assembly is processed twice, improving the sealing performance.
[0006] Preferably, the inner plastic layer is step-shaped.
[0007] Preferably, the wall thickness of the inner plastic layer is equal everywhere;Through the above setting, since the wall thickness of the inner plastic layer is equal, and the inner plastic layer is step-shaped, when the outer plastic layer is plasticized on the basis of the inner plastic layer, the outer plastic layer will also form a structure with uniform wall thickness due to the influence of the inner plastic layer, avoiding local plastic wall thickness that is too thick or too thin, ensuring uniform wall thickness, which will not produce pores due to excessive wall thickness, and will not crack due to thin wall thickness, and through the two plastic layers, the requirements for hot runner, pressure and temperature in the plasticizing process are reduced, which is simple to process and easy to use.
[0008] Preferably, the wall thickness of the outer plastic layer is equal everywhere.
[0009] Compared with the prior art, the stator assembly has the advantages of good sealing effect, no easy leakage, easy processing and high practicability. BRIEF DESCRIPTION OF DRAWINGS
