Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a motor with an upper end cover having a mounting structure, such as... Figure 1 and Figure 2 As shown, the motor includes a main housing 100, an upper end cover 200, a lower end cover 300, a stator assembly 400, a rotor assembly 500, and a rotating shaft 600. The upper end cover 200 and the lower end cover 300 are fixed to the upper and lower ends of the main housing 100, respectively. The stator assembly 400 and the rotor assembly 500 are both disposed within the main housing 100. The rotating shaft 600 is connected to the rotor assembly 500, and passes through the upper end cover 200 and extends above it. The upper end cover 200 naturally has a through hole, through which the rotating shaft 600 passes, extending above the upper end cover 200. After the motor is energized, the stator assembly 400 and the rotor assembly 500 cooperate to drive the rotor assembly 500 to rotate the rotating shaft 600.

[0029] The outer diameter of the upper end cover 300 is greater than the outer diameter of the main shell 100, which provides space for the mounting structure to adapt to the mounting position, and the main shell 100 can pass through the avoidance hole in the center of the mounting position. The outer peripheral surface of the upper end cover 200 is provided with a plurality of mounting structures, which include mounting lugs 210 integrally formed with the upper end cover 200, and the mounting lugs 210 are provided with through mounting holes 220. Since the mounting structure is integrally formed with the upper end cover 200, it is not necessary to additionally fix the mounting structure, which simplifies the structure of the entire motor. When assembling, the upper end cover 200 is installed at the same time as the mounting structure, which facilitates assembly.

[0030] For example, the mounting position is provided on a mounting plate, the mounting plate is provided with an avoidance hole and a plurality of through holes arranged around the avoidance hole, the plurality of through holes are respectively connected to the plurality of mounting holes 220, the main shell 100 is arranged in the avoidance hole, and a connecting member such as a screw is used to pass through the mounting hole 220 of the mounting lug 210 and the through hole of the mounting plate, and then the screw is locked and matched through a nut to fix the entire motor on the mounting plate.

[0031] In some embodiments, the motor with the upper end cover having the mounting structure also includes a screw 700, the top surface of the upper end cover 200 is provided with a first through hole, the upper end surface of the main shell 100 is provided with a second through hole extending to the lower end surface, and the lower end cover 300 is provided with a threaded hole. The first through hole, the second through hole and the threaded hole are sequentially connected, and the screw 700 passes through the first through hole and the second through hole and is fixed in the threaded hole. In this way, the main shell 100, the upper end cover 200 and the lower end cover 300 can be locked and fixed together by a group of screws 700, without the need to provide a fixing member for the upper end cover 200 and the lower end cover 300, further simplifying the overall structure.

[0032] Among them, the screw 700 can be provided with a plurality of screws, which are uniformly distributed relative to the axis of the upper end cover 200 to enhance the fixing effect.

[0033] Further, the lower end surface of the main shell 100 is provided with a plurality of downward extending positioning lugs 110, and the top surface of the lower end cover 300 is provided with a positioning groove matched with the positioning lugs 110. Specifically, the number, position, shape and size of the positioning groove are matched with the number, position, shape and size of the positioning lugs 110, respectively, and the positioning lugs 110 are inserted into the matched positioning grooves.

[0034] When installing the lower end cover 300, the positioning protrusions 110 are aligned with the positioning grooves, and the positioning protrusions 110 are inserted into the positioning grooves, so that the lower end cover 300 is in the correct installation position, the threaded holes are aligned with the second through holes, and the screws 700 are easily inserted into the threaded holes to quickly lock and fix the main shell 100, the upper end cover 200 and the lower end cover 300 together. At the same time, the positioning protrusions 110 can limit the transverse movement of the lower end cover 300 relative to the main shell 100, so that the lower end cover 300 can be more stably fixed on the main shell 100.

[0035] In some embodiments, the positioning protrusions 110 are integrally formed with the main shell 100.

[0036] Of course, the upper end face of the main shell can also be provided with a plurality of upwardly extending positioning protrusions, and the bottom face of the upper end cover can also be provided with positioning grooves matched with the positioning protrusions of the upper end face of the main shell. Specifically, the number, position, shape and size of the positioning grooves are matched with the number, position, shape and size of the positioning protrusions of the upper end face of the main shell, respectively. The positioning protrusions of the upper end face of the main shell are inserted into the positioning grooves on the bottom face of the upper end cover matched therewith to position the upper end cover, facilitating the quick assembly of the upper end cover.

[0038] Further, the outer diameter of the lower end cover 300 is equal to the outer diameter of the main shell 100, so that in the radial direction, the lower end cover 300 does not protrude from the main shell 100, facilitating the outer diameter of the lower end cover 300 to pass through the reserved avoidance hole of the main shell 100 at the installation position.

[0039] In some embodiments, the top face of the upper end cover 200 is provided with a boss 230 and a positioning ring groove 240, the rotating shaft 600 passes through the boss 230, and the positioning ring groove 240 is arranged around the boss 230. The components driven by the motor can be matched with the boss 230 and the positioning ring groove 240 to make the upper end cover 200 abut against the to-be-driven components, reduce the assembly gap, and can play the role of mutual alignment.

[0040] For example, the rotating shaft 600 can be connected with a blade to drive the blade to rotate, and the surface of the outer shell of the blade is provided with a groove and a positioning ring, the boss 230 can be inserted into the groove, and the positioning ring can be inserted into the positioning ring groove 240.

[0042] In some embodiments, the outer circumferential surface of the rotating shaft 600 is provided with a limiting convex ring 620, and when the driven device is sleeved on the rotating shaft 600, the driven device can be blocked by the limiting convex ring 620, thereby limiting the depth of the insertion of the rotating shaft 600 into the driven device, and avoiding over-insertion.

[0043] The rotating shaft 600 can include two sections, one of which has an outer diameter smaller than that of the other section, and the connecting part of the two sections of the rotating shaft 600 forms the limiting convex ring 620.

[0044] In some embodiments, the rotating shaft 600 is provided with a first bearing 630 and a second bearing 640, and the inner rings of the first bearing 630 and the second bearing 640 are sleeved on the rotating shaft 600.
