DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] The end cover assembly includes an end cover 1 and a base 2. The base 2 includes a bottom plate 21. The bottom plate 21 is fixed to the motor body 5 through a fixing member 4 and a mounting hole 211 on the bottom plate 21. Connecting seats 22 are evenly provided on the bottom plate 21. The end cover 1 and the connecting seats 22 are detachably connected. In this way, when repairing the interior of the motor body 5, only the end cover 1 needs to be removed, which facilitates maintenance of the motor body 5.

[0027] Furthermore, a movable cavity 221 and a telescopic cavity 222 are respectively provided in the connecting seat 22, a fixed rod 223 is fixed in the movable cavity 221, an upper frustum 224 is fixed on the top of the fixed rod 223, a lower frustum 225 is movably sleeved on the periphery of the fixed rod 223, the lower frustum 225 is symmetrical with the upper frustum 224, a telescopic rod 226 is sleeved in the telescopic cavity 222, and an elastic member 227 is connected between the telescopic rod 226 and the telescopic cavity 222, and the elastic member 227 can be a spring; in addition, connecting rods 12 are evenly provided at the bottom of the end cover 1, a locking block 13 is fixed at the bottom of the connecting rod 12, a card block 14 is sleeved in the locking block 13, the card block 14 matches the upper frustum 224 and the lower frustum 225, the bottom of the card block 14 is inclined, and an elastic member 15 is connected between the card block 14 and the inner cavity of the locking block 13. The elastic member 15 can be a spring;

[0028] When the end cover 1 is installed, the corresponding locking block 13 on the end cover 1 is inserted into the corresponding active cavity 221, and then the end cover 1 is pressed downward, so that the blocking block 14 is squeezed by the upper frustum 224 and retracted into the locking block 13, and the elastic member 1 15 is compressed. When the blocking block 14 moves to the bottom of the upper frustum 224, the blocking block 14 is separated from the upper frustum 224, that is, the upper frustum 224 releases the restriction on the blocking block 14. At the same time, the telescopic rod 226 squeezes the elastic member 227, so that the elastic member 227 always has an upward rebound tendency, and the rebound of the elastic member 15 makes the blocking block 14 extend and rest against the bottom of the upper frustum 224, thereby fixing the locking block 13 and then fixing the end cover 1. When the end cover 1 needs to be removed, the end cover 1 is pressed downward, so that the blocking block 14 moves downward and is squeezed and compressed into the locking block 13 by the lower frustum 225, and then moves downward. The locking block 13 is then lifted and released by the elastic member 227, and the locking block 14 is moved upwards, until the lower cone 225 contacts the bottom of the upper cone 224. At this time, the locking block 13 is lifted by the telescopic rod 226 and continues to move upwards, and the locking block 14 is slowly retracted into the locking block 13 again. Since the lower cone 225 and the upper cone 224 contact each other, the locking block 14 is directly moved above the upper cone 224, and the restriction of the upper cone 224 on the locking block 14 is released. At this time, the end cover 1 can be directly removed, so that the interior of the motor body 5 is exposed to the outside, which is convenient for maintenance.

[0029] Furthermore, a limiting plate 228 is symmetrically provided on the inner wall of the movable cavity 221, and the locking block 13 is in contact with the inner wall of the movable cavity 221, and the outer side of the locking block 13 abuts against the inner side of the limiting plate 228, which can improve the stability of the locking block 13, thereby ensuring that the end cover 1 is more secure after installation;

[0030] Furthermore, the surface of the end cover 1 is tilted outward in the middle, which can prevent external dust or water stains from entering the motor body 5 and causing damage to the motor body 5;

[0031] Furthermore, a shaft sleeve 11 is provided on the top of the end cover 1, and the shaft sleeve 11 can ensure the stability of the rotating shaft of the motor body 5;

[0032] Furthermore, a filter screen 3 is installed between two adjacent connecting seats 22. The bottom and top of the filter screen 3 are respectively against the bottom plate 21 and the end cover 1. The filter screen 3 can effectively prevent external dust from entering the interior of the motor body 5 on the one hand, and can also improve the heat dissipation effect of the motor body 5 on the other hand. The motor includes the above-mentioned end cover assembly.

[0033] A washing machine comprises the above-mentioned motor.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
