Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model provides a pair of motor housing, include: the bottom cover comprises a bottom cover 1 and an end cover 2, wherein the edge of the bottom cover 1 protrudes upwards to form a blocking edge 101, the blocking edge 101 extends outwards and horizontally to form a locking edge 102, a motor casing locking piece 3 is arranged on the locking edge 102, the edge 201 of the end cover extends downwards to be attached to the outer side surface of the blocking edge 101, extends outwards and horizontally to the position of the locking edge 102, and is connected with the bottom cover 1 into a whole through a motor casing locking assembly;

specifically, end cover edge 201 is set to paste tight flange 101 downwardly extending then level outwards extends to locking edge 102, is connected as an organic wholely with bottom 1 through motor casing locking Assembly, and like this, end cover 2 middle part and bottom 1 middle part just can form an inclosed cavity 4 for install electrical component, because motor casing retaining member 3 is outside being independent of cavity 4, like this, can not cause the motor operation abnormal sound in cavity 4 at locking motor casing in-process iron fillings.
