[0002] With the development of modern industry and household appliances, motors, as key components of power transmission, play a vital role in various applications.

[0003] Traditional motor designs usually use screws, welding, clamping and other methods to connect the motor housing and the end cover.

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0027] See also Figures 1-6A motor structure includes a motor housing 1 and two end covers 2 arranged at both ends of the motor housing 1. The end cover arranged on the left side of the motor housing 1 is the left end cover, and the end cover arranged on the right side of the motor housing 1 is the right end cover. A rotor 3 is arranged between the left end cover and the right end cover. An output shaft 4 is provided at the middle position of the rotor 3, and at least one end of the output shaft 4 extends outside the motor housing 1.

[0028] As one embodiment, a bearing 5 is provided between the output shaft 4 and the end cover 2 , for example, corresponding bearings 5 ​​are provided between the left end cover and the output shaft 4 and between the right end cover and the output shaft 4 , respectively.

[0029] In this embodiment, the motor housing 1 is cylindrical in shape, including its inner wall and outer wall. The motor housing 1 is hollow inside with both ends open. Correspondingly, the end cover 2 and the outer wall of the motor housing 1 are circular in shape.

[0030] In this embodiment, both ends of the motor housing 1 are provided with edges 11 for limiting the end cover. Specifically, during the process of applying force to pull the end cover 2 outward, the motor housing 1 plays a limiting role.

[0031] As one of the embodiments, the edging 11 is formed by bending the end of the motor housing 1 inward, and the shape of the edging 11 is circular, including its inner edge. After the edging 11 is formed, the diameter of its inner edge is smaller than the inner diameter of the motor housing 1, thereby limiting the end cover 2 to match the size and shape of the inner wall of the motor housing 1.

[0032] As one embodiment, the inner wall of the edging 11 fits in contact with the outer wall 21 of the main body of the end cover 2 .

[0033] In order to further enhance the limiting effect of the motor housing 1 on the end cover 2, in this embodiment, the end of the motor housing 1 includes a circumferentially arranged groove 12, and the end cover 2 includes a flange 22 that is clamped in the groove 12. As one of the implementation methods, the flange 22 is also circumferentially arranged on the end cover 2.

[0034] See also Figure 5 and Figure 6 , is a schematic diagram of another form of the present application, in which an open slot 13 is opened at the end of the motor housing 1. The number of the open slots 13 can be selected according to actual needs. For example, if there are two, the end cover 2 includes matching heads 23 whose number and position correspond to the open slots 13. After the end cover 2 is installed, the matching heads 23 are located in the open slots 13. At the same time, a fastener 6 adapted to the open slot 13 is also provided. The fastener 6 is snap-connected or riveted to the matching head 23, so that the corresponding end cover 2 and the motor housing 1 are assembled into one.

[0035] In this embodiment, a fan is installed on the motor rotor. The fan is arranged on the inner side of the end cover, that is, located inside the motor housing and between the two end covers, forming a built-in layout.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
