Based on the above, the general concept of the embodiment of the utility model is to provide a motor controller upper cover 100, which mainly includes three major components: a first cover 110, a sealing member 120 and a second cover 130. The first cover 110 is provided with an inspection hole 1111, and the first cover 110 is used to be arranged on the controller assembly 200 of the drive motor 10, so as to facilitate inspection through the inspection hole 1111; the second cover 130 is covered on the first cover 110 and connected to the first cover 110, and the sealing member 120 is arranged in a ring on the circumference of the inspection hole 1111, and is located between the first cover 110 and the second cover 130. After the second cover 130 is connected to the first cover 110, the second cover 130 presses against the sealing member 120, so that the sealing member 120 is tightly fitted with the first cover 110 and the second cover 130, thereby achieving the sealing of the inspection hole 1111. By designing the upper cover plate 100 of the motor controller, the inspection hole 1111 is sealed without the need for gluing, so that the inspection hole 1111 is not prone to air leakage in complex environments such as high temperature and humidity. In addition, the second cover plate 130 does not need to be removed by glue when being disassembled, which helps to improve the convenience of maintenance.

Based on the above general concept, with reference to Figures 1 to 7, an embodiment of the utility model first provides a motor controller upper cover 100, including a first cover 110, a sealing member 120 and a second cover 130; a through inspection hole 1111 is opened on the first cover 110; the second cover 130 is covered on the inspection hole 1111 and connected to the first cover 110; the sealing member 120 is arranged in a ring on the circumference of the inspection hole 1111, and is located between the second cover 130 and the first cover 110, and the sealing member 120 is arranged to be pressed by the second cover 130 to fit tightly with the first cover 110 and the second cover 130.

It should be understood that in the motor controller upper cover 100 provided in this embodiment, one side of the first cover 110 is used to cover the controller assembly 200, and the other side is used to connect the second cover 130. The inspection hole 1111 opened on the first cover 110 can be a circular through hole, a square or other shaped special-shaped hole, and the opening position of the inspection hole 1111 is mainly to facilitate the exposure of the relevant components of the controller assembly 200 through the inspection hole 1111 for easy maintenance. In addition, the sealing member 120 is annular and is arranged in a ring on the circumference of the inspection hole 1111, so that when pressed, the periphery of the inspection hole 1111 can be completely sealed to improve the air tightness of the inspection hole 1111.

It should be noted that, in general, a casting structure can open a groove at the edge of the opening to insert the seal 120, so as to meet the sealing requirements. However, due to the limitations of the stamping process, stamping parts are usually unable to directly open a groove on the surface to insert the seal 120 to meet the airtightness requirements. If a groove is required for a stamping part, an additional processing step is required, which makes its overall molding more complicated. Therefore, the motor controller upper cover plate 100 structure provided in this embodiment can be applied to most stamping part opening cover plate sealing structures, such as stamping part opening cover plate structures that require sealing other than the controller upper cover plate. When processing the motor controller upper cover plate 100 provided in this embodiment, the first cover plate 110 and the second cover plate 130 can be directly stamped out to cooperate with the seal 120 to meet the airtightness requirements. There is no need to open additional grooves, thereby simplifying the process to save costs and improve production efficiency.
