The electric automobile is a development hotspot of the current automobile industry, the pure electric automobile, an energy-saving and environment-friendly automobile, is no longer a concept, various large automobile factories are in explosive development and continuously launch new automobile models to come into the market, and a new automobile field is gradually developed. The integrated motor controller is a control component of a power motor and other vehicle accessory motors (an electronic hydraulic oil pump steering motor, an air compressor motor and the like), and has very high reliability requirements for a pure electric vehicle. The sealing within the integrated controller enclosure is also very critical as an important attribute of product reliability, and its sealing rating must typically reach IP 67.
The existing controller cover plate sealing is mostly that a sealing ring is assembled in a sealing ring groove of a lower part, so that the lower part is required to be provided with a corresponding sealing ring. According to the minimum wall thickness requirement of an aluminum die casting, the wall thickness of at least 3.5mm must be arranged on the periphery of the groove of the sealing ring, and the size of the groove of the sealing ring (about 2.5-3mm deep) is added, so that the ring surrounds the structure of the sealing ring and occupies a space of at least 6mm, the structure is difficult to design for the originally compact internal space of the integrated motor controller, especially for the position of a high-voltage electric device, the electric device arrangement is considered, and the insulation requirements such as creepage distance and electric clearance are met (a cover plate and a shell are generally aluminum die castings and can conduct electricity), and the structural part design of the surrounding parts is more difficult.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to solve the technical problem that a motor controller's apron seal structure is provided to reach sealed effectual, and do not occupy inner space's purpose.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
this motor controller's apron seal structure, the apron is located motor controller's box top, the marginal lower part of apron is equipped with the sealing washer mounting groove, and the sealing washer mounting groove internal fixation has the sealing washer, the sealing washer has the part to be located the sealing washer mounting groove outside.
Furthermore, the edge of the cover plate is provided with a downward flanging, and the sealing ring mounting groove is formed in the end face of the flanging.
And a sealing ring mounting groove on the cover plate is provided with a part of arc-shaped structure.
The bottom surface of the sealing ring mounting groove is provided with a bulge, and the sealing ring in the sealing ring mounting groove is provided with a positioning groove matched with the bulge.
And the side wall of the sealing ring is provided with a convex limiting rib.
And an annular groove is formed in the outer end face of the sealing ring.
The protrusion is located at the middle position of the bottom surface of the groove.
The limiting ribs are arranged on the outer wall of the sealing ring and are a group which is arranged side by side at intervals.
Compared with the prior art, the utility model, have following advantage:
the cover plate sealing structure of the motor controller is reasonable in design, and the sealing ring is integrated on the cover plate, so that the sealing is reliable; the internal space of the controller box is irrelevant to the wall thickness of the sealing ring, so that a lot of space can be saved; the integrated arrangement reduces the installation process and improves the production efficiency.

Fig. 5 is a schematic view of the sealing ring of the present invention located in the cover plate.
In the figure:
1. the sealing ring mounting structure comprises a cover plate, 101 mounting holes, 102 sealing ring mounting grooves, 2 box bodies, 3 sealing rings and 301 limiting ribs.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, in the cover plate sealing structure of the motor controller, a cover plate 1 is positioned above a box body 2 of the motor controller, a sealing ring installation groove 102 is formed in the lower portion of the edge of the cover plate 1, a sealing ring 3 is fixed in the sealing ring installation groove, and part of the sealing ring 3 is positioned outside the sealing ring installation groove; the cover plate is conveniently provided with a mounting hole 101, and the cover plate is connected with the box body through a screw, so that the sealing ring is extruded to generate a better sealing effect.
The sealing ring 3 is integrated on the cover plate 1, so that the sealing is reliable; the internal space of the controller box is irrelevant to the wall thickness of the sealing ring, so that a lot of space can be saved; the integrated arrangement reduces the installation process and improves the production efficiency.
The edge of the cover plate 1 is provided with a downward flange, a sealing ring mounting groove is formed in the end face of the flange, a sealing ring mounting groove 102 is formed in the upper part of the sealing ring mounting groove, the wall thickness of a body of the sealing ring groove is arranged outside but not inside a box body, a sealing surface of the box body is a plane, a sealing ring is assembled in the middle of the sealing ring mounting groove, and the two parts are connected through screws and then extrude the sealing ring to generate a sealing effect. The outer end face of the sealing ring is provided with an annular groove, so that the sealing effect is good.
The sealing ring mounting groove on the cover plate is provided with a part of arc-shaped structure; the bottom surface of the sealing ring mounting groove is provided with a bulge, and the sealing ring in the sealing ring mounting groove is provided with a positioning groove matched with the bulge; the preferred protrusion is located at the middle position of the bottom surface of the groove, and the positioning is reliable.
