Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and more specifically, particularly relates to a motor end cover assembly and a motor mounting structure. Background Art

[0002] Nowadays, many household appliances need to be driven by motors, such as air conditioners, refrigerators, etc. Traditional motors are assembled from end covers, a casing, a stator assembly, a rotor assembly and 6-8 assembly screws.

[0003] For example: Application No. CN201710522084.9 relates to the field of motor technology, and discloses a motor end cover assembly, a motor, and a motor mounting structure. The motor end cover assembly includes a cover body, a mounting stud, and an elastic limit card. A through hole is formed on the cover body, and the mounting stud passes through the through hole to a set position. The outer protruding section of the mounting stud extending to the outside of the cover body has a threaded portion. The elastic limit card is clamped on the outer protruding section and contacts the outer side of the cover body to limit the axial reverse movement of the mounting stud. The elastic limit card can be compressed under the action of the motor mounting plate. Since the elastic limit card is clamped to limit the axial reverse movement of the mounting stud, the reliable positioning of the mounting stud is ensured, and it will not fall off and fall into the motor under external influences. The thickness of the elastic limit card is less than the thickness of the existing nut, and the thickness of the elastic limit card is further reduced after being compressed by the motor mounting plate, which will make the overall length of the motor smaller, thereby meeting the installation requirements of a limited given space.

[0004] Based on the above, when installing the existing motor end cover, the screws are installed to the threaded holes around the motor end cover, and then the threaded holes in the middle of the motor end cover are installed. When the motor is used in a humid environment, rust easily appears on the screws and the threaded holes. The rust makes the screws fit the threaded holes, which makes it difficult to remove the screws. Utility Model Content
