AI Technical Summary

Technical Problem

The thermal nesting assembly method of existing motors and control units causes the sealant to be unable to be fully filled, affecting the sealing effect, and the sealing effect of the O-ring is poor, which cannot meet the dimensional tolerance changes caused by thermal expansion and contraction.

Method used

A liquid sealing structure including a motor housing, a control unit radiator and a sealing structure is designed. The combination of a rubber overflow groove, a rubber overflow bevel, a rubber overflow sealing surface and a rubber overflow chamfer is used to ensure that the sealing glue is fully filled and effective. Attached.

Benefits of technology

It realizes full filling and effective adhesion of sealant, improves the sealing effect between the motor and the control unit, and is suitable for automated assembly.

Abstract

The utility model relates to the technical field of sealing, in particular to a liquid sealing structure of a motor and a control unit, which comprises a motor casing and a control unit radiator, the motor casing is sleeved outside the control unit radiator, and a glue overflow groove is arranged in the middle of a contact surface of the control unit radiator and the motor casing. The rear portion of the contact face of the control unit radiator and the motor shell is a sealing face, the end of the sealing face is vertically provided with a glue overflowing sealing face, the joint of the sealing face and the glue overflowing groove is provided with a gluing inclined face, and the outer side of the end of the motor shell is provided with a glue overflowing chamfer. And sealant is filled in the glue overflowing groove, on the gluing inclined surface, in a gap between the sealing surface and the motor shell and in a gap between the glue overflowing groove and the motor shell. Compared with the prior art, the utility model has the advantages that the effectiveness of the sealant is ensured, and the sealant is fully filled, so that the sealing effect between the motor and the control unit is ensured. The automatic assembling device can be applied to automatic assembling of a production line.
