Motor end cover and motor

Abstract

The present invention discloses a motor end cover and a motor. The motor end cover is characterized in that the motor end cover is provided with an interchangeable structure, and the motor end cover can be connected to the motor housing through the interchangeable structure. The connection method of the motor end cover and the motor housing includes a first connection method and a second connection method. The first connection method and the second connection method use the connection line between the motor end cover and the connector as a reference axis, and the motor end cover is obtained by rotating relative to the reference axis. The present invention provides two installation methods for the motor end cover, so that the motor end cover and the motor housing can adapt to different installation conditions, improve the applicability, and in different installation conditions, only the installation angle of the motor end cover needs to be changed, which is convenient to use. In the two installation methods, the structure of the motor end cover and the motor housing remains unchanged, so the motor end cover and the motor housing only need one set of molds, which greatly saves the manufacturing cost.

[0026] The present invention is described in detail below in conjunction with the accompanying drawings:

[0027] like Figures 1 to 5 As shown, the motor end cover 1 of this embodiment is provided with an interchangeable structure, and the motor end cover 1 can be connected to the motor housing 2 through the interchangeable structure. The connection mode between the motor end cover 1 and the motor housing 2 includes a first connection mode and a second connection mode. The first connection mode and the second connection mode use the connecting line between the motor end cover 1 and the connector 5 as the reference axis P, and the motor end cover 1 is rotated relative to the reference axis P.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the interchangeable structure includes a plurality of through holes 3 and slots 4, each of which is evenly distributed in a ring along the motor end cover 1, and the through holes 3 and slots 4 are arranged to be snap-fitted with the motor housing 2. The number of the through holes 3 and slots 4 is 9, of which two slots 4 can interchangeably correspond to the positions of the connector 5, and when one slot 4 corresponds to the connector 5, the other slot 4 is snap-fitted with the motor housing 2. The angle difference between the two interchangeable slots 4 is 80°. The motor end cover 1 is provided with two mounting holes 6 in the radial direction, and the center line I of the through hole 3 located between the two interchangeable slots 4 coincides with the center line I of the mounting hole 6 of the motor end cover 1. In this embodiment, the two slots 4 are the first slot 41 and the second slot 42.

[0029] like Figure 3 As shown, the motor of this embodiment includes: the motor end cover 1 mentioned above; a motor housing 2, and the motor housing 2 is connected to the motor end cover 1. Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the end of the motor housing 2 is provided with a plurality of buckles 9, and the buckles 9 are arranged to be snap-fitted with the through holes 3 and slots 4 of the motor end cover 1. The structure of the buckle 9 includes two deformable bodies 10 and a fixed body 11, and the two deformable bodies 10 and the fixed body 11 are arranged at the end of the motor housing 2. The two deformable bodies 10 are respectively arranged on both sides of the fixed body 11 and the deformable bodies 10 and the fixed body 11 are arranged at intervals. When the through holes 3 and slots 4 of the motor end cover 1 are snap-fitted with the two deformable bodies 10, the deformable bodies 10 are deformed, and the deformable bodies 10 have a tendency to return to their original shape when deformed. The deformable bodies 10 are integrated with the motor housing 2, and the deformable bodies 10 are spaced apart from other parts of the end of the motor housing 2.

[0030] When in use, one installation method of the motor end cover 1 is as follows: Figure 4As shown, the angle between the center line I of the mounting hole 6 and the reference axis P is 40° to the left of the reference axis P. At this time, the first slot 41 is engaged with the motor housing 2, and the second slot 42 is an empty slot, and the second slot 42 corresponds to the position of the connector 5. Another installation method of the motor end cover 1 is as follows: Figure 5 As shown, the angle between the center line of the mounting hole 6 and the reference axis P is 40° to the right of the reference axis P. At this time, the second slot 42 is engaged with the motor housing 2, and the first slot 41 is an empty slot, and the first slot 41 corresponds to the position of the connector 5. In both installation methods, as long as the motor end cover 1 changes its angle, the motor, the connector 5 and the motor housing 2 do not need to be changed. When using, any installation method can be selected according to the actual situation.

[0031] The present invention allows the motor end cover to adapt to two different installation methods by setting the motor end cover structure. Moreover, in these two installation methods, only the motor end cover needs to change the installation angle, and the motor housing, motor and connector do not need to be changed, which is simple and convenient. At the same time, in the two installation methods, the structure of the motor end cover and the motor housing remains unchanged, so the motor end cover and the motor housing only need one set of molds, which greatly saves manufacturing costs. The present invention provides two installation methods for the motor end cover, so that the motor end cover and the motor housing can adapt to different installation conditions, improve applicability, and in different installation conditions, only the installation angle of the motor end cover needs to be changed, which is easy to use.

[0032] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutes that can be thought of by those skilled in the art are all within the protection scope of the present invention.
