Embodiment 1

[0021] See attached Figure 1-2 As shown, a static sealing structure of the end face of a motor with high reliability, the static sealing structure of the end face is set between the housing 1 and the cover body 2 of the motor, and a ring of protrusions is provided on the port of the housing toward the cover body. Rib 11 , the cover body 2 is provided with a ring of convex edges 21 facing the housing 1 , when the cover body 2 is covered on the housing 1 through a pressing structure, the convex edges 21 are located on the outer periphery of the convex ribs 11 .

[0022] The cover body 2 is circular, and the cover body 2 is an end cover of the motor.

[0023] The pressing structure includes a first mounting hole provided on the cover 2, a second mounting hole and a mounting nail provided on the housing, and the cover 2 and the housing 1 pass through the first mounting hole and the second mounting hole. The holes are connected with the mounting nails 4; this compression structur...

Abstract

The invention provides a high-reliability motor end face static sealing structure. The end face static sealing structure is arranged between a housing and a cover body of a motor; a circle of convex rib is arranged on a port of the housing towards the cover body; a circle of convex edge is arranged on the cover body towards the housing; and when the cover body is covered on the housing through a pressing structure, the convex edge is located on the periphery of the convex rib. The end face static sealing structure comprises a sealing heat-insulation pad. The sealing heat-insulation pad is a sheet-shaped body; the middle portion of the sheet-shaped body serves as a heat insulation part; and the periphery of the sheet-shaped body is provided with a circle of flange to serve as a sealing part. A sealing groove corresponding to the flange is formed in the cover body; the groove bottom of the sealing groove serves as a first sealing surface and makes contact with and seals the top surface of the flange; the top surface of the convex rib of the housing is used as a second sealing surface and makes contact with and seals the bottom surface of the flange; at least one heat insulation groove is formed in the inner surface of the cover body in a concave mode; the portion, corresponding to the heat insulation groove, of the face, facing the cover body, of the heat insulation part is a heat insulation face; and the heat insulation face and the heat insulation groove form a heat insulation cavity.

Description

technical field [0001] The invention relates to the field of permanent magnet synchronous motors, in particular to a high-reliability static sealing structure for motor end faces. Background technique [0002] The permanent magnet synchronous motor is used in the electric vehicle industry, and the protection level of the enclosed space inside the motor is high, and the sealing level of IP68 needs to be achieved. The first number 6 after the IP means that foreign objects and dust must be completely prevented from intrusion, and the second number is 8 means that it can withstand continuous immersion in water with a depth of more than 1 meter without being affected. And because there is a large temperature difference between the internal space and the external environment when the motor is running, the air moisture inside the motor often condenses on the junction box or the motor protection cover. If things go on like this, it is likely that a certain amount of moisture will a...
