A controller unit 200, the controller unit 200 has two parallel controller ends 2001, and a controller edge 2002 extending between the two controller ends 2001, the two controllers The thickness b of the controller unit is defined between the ends 2001, and the controller unit 200 is installed on a motor end 1001 in such a manner that the controller end 2001 is parallel to the motor end 1001, And the controller edge portion 2002 is attached to the motor edge portion 1002 at a ratio of not less than 50%.

Since the motor end 1001 is substantially circular, the motor unit 100 is cylindrical, the controller unit 200 is held on one side in the thickness direction of the motor unit 100, and the controller end 2001 and the motor end 100 are arranged as close as possible, so the sum of the thickness a of the motor unit and the thickness b of the controller unit forms the overall thickness of the mechanical assembly, and the motor unit 100 and the controller unit 200 are arranged compactly in the thickness direction, which reduces the thickness of the mechanical assembly and further reduces the overall volume.

In addition, the edge portion of the controller 2002 is attached to the edge portion of the motor 1002 at a ratio of not less than 50%, that is, the edge portion of the controller 2002 overlaps with the edge portion of the motor 1002 by not less than 50%. part, to prevent the controller edge portion 2002 from being protruded relative to the motor edge portion 1002, that is, increasing the radial dimension and increasing the volume of the mechanical assembly. Therefore, this embodiment not only makes the The motor unit 100 and the controller unit 200 are arranged compactly along the thickness direction to reduce the thickness and prevent the controller unit 200 from expanding radially along the motor unit 100, thus effectively reducing the overall volume of the mechanical assembly In order to make the mechanical assembly suitable for different fields, so as to achieve standardization and universality.

As shown in FIG. 1 , the controller edge portion 2002 is not attached to the motor edge portion 1002 , and is kept within the area surrounded by the motor edge portion 1002 . It can be seen that the part corresponding to the controller edge 2002 and the motor edge 1002 is not attached, which is recessed toward the inside of the controller edge 2002. Compared with the cylindrical motor unit 100, the control The volume of the device unit 200 is further reduced, thereby realizing the miniaturization of the volume of the mechanical assembly.

As shown in Figures 1 to 3, the motor unit 100 also has a plurality of connecting rib assemblies 110, and a plurality of connecting rib assemblies 110 extend outward from the motor edge 1002, and along the motor edge 1002 are arranged at intervals, and the controller unit 200 also has a plurality of connection ears 211, and the plurality of connection ears 211 extend outward from the edge portion 2002 of the controller and are arranged at intervals along the edge portion 2002 of the controller, The connecting ear 211 can be opposite to the connecting rib assembly 110, and is fastened by a first fastener 310, and the first fastener 310 is hidden between the connecting ear 211 and the connecting rib assembly 110 Inside.

Specifically, the connecting rib assembly 110 extends in the thickness a direction of the motor unit, and both ends are respectively flush with the two motor end portions 1001 , and a plurality of the connecting rib assemblies 110 are arranged at equal intervals. The connecting rib assembly 110 is also provided with a threaded hole for screwing with the first fastener 310 , that is, when the connecting ear 211 is opposite to the connecting rib assembly 110 , the first fastener 310 passes through the connecting ear 211, and is screwed with the threaded hole on the connecting rib assembly 110, so that the controller unit 200 is tied and fixed on one of the motor end 1001 of the motor unit 100 . In addition, a plurality of connecting ears 211 are also equidistantly arranged along the edge portion 2002 of the controller. It can be seen that the connection points of the connection between the controller unit 200 and the motor unit 100 through the first fasteners 310 are evenly arranged, thereby improving the connection strength between the two.

More specifically, the cross-section of the connecting rib assembly 110 is approximately circular, and the arc of the circle is not less than 180°, wherein the connecting rib assembly 110 not only serves to screw the first fastener 310, but also to The function of the tie to fix the controller unit 200 also improves the strength of the housing of the motor unit 100 . Compared with the connecting rib assembly 110, the motor edge portion 1002 only partially extends outward, avoiding the defect that the whole volume becomes larger due to the entire outward extension.

Preferably, the first fastener 310 is hidden in the connecting ear 211 and the connecting rib assembly 110, which not only plays an aesthetic role, but also prevents damage due to the exposure of the first fastener 310 , thereby affecting its connection effect.

As shown in FIG. 1 , the number of the connecting rib assemblies 110 is greater than the number of the connecting ears 211 , and at least one connecting rib assembly 110 is held between two adjacent connecting ears 211 .

It can be seen that the distance between two adjacent connecting rib assemblies 110 is 1/2 of the distance between two adjacent connecting ears 211 . And the number of the connecting rib components 110 is twice the number of the connecting ears 211 .

As shown in Figures 1 to 3, the controller unit 200 includes two controller housings 220 arranged and assembled along the thickness b of the controller unit, and a plurality of controller housings 220 arranged on the edge of the controller 2002 and tied in two There are two connection nodes 212 of the controller housing 220, the connection nodes 212 are arranged in a staggered manner from the connection ears 211, and can be opposite to the connection rib assembly 110.

When the two controller housings 220 are assembled, the two connecting plates 2121 on them abut and remain in the middle of the thickness b of the controller unit, and the connecting ear 211 is close to the motor The way the unit 100 is held on the controller edge 2002 . This allows the connecting ear 211 to be close to the connecting rib assembly 110 to further prevent the first fastener 310 from being exposed.

Wherein, the thickness of the connecting ear 211 is relatively thin, which is enough to hang the head of the first fastener 310, and the first fastener 310 and the second fastener 320 can be bolts, etc. . The thickness of the connecting plate 2121 located in different controller housings 220 may be different, that is, the connecting plate 2121 close to the motor unit 100 has a thinner thickness, which is used to hang the head of the second fastener 320, The connecting plate 2121 away from the motor unit 100 has a thicker thickness and is used for screwing with the second fastener 320 .

As shown in Fig. 1 and Fig. 2, the motor unit 100 includes two motor casings 120, and a plurality of connecting ribs 111 are arranged at equidistant intervals around the circumference of each of the motor casings 120. When the motor casings 120 are arranged and assembled along the thickness a of the motor unit, the connecting ribs 111 on the two motor casings 120 correspond one-to-one to form the connecting rib assembly 110, which is hidden inside the connecting rib assembly 110 There is a third fastener connecting the two motor housings 120 , and the third fastener can also be a bolt or the like.

The left and right sides cooperate with the connecting channel.

As shown in FIG. 2 , the diameter of the motor end portion 1001 is greater than the thickness a of the motor unit, so that the motor 100 is formed as a disc motor. By adopting the disc motor, the thickness a of the motor unit is reduced, further realizing the miniaturization design of the mechanical assembly.

As shown in Figures 1 to 3, the mechanical assembly also has a heat dissipation structure 400, and the heat dissipation structure 400 is arranged on the motor end 1001, the motor edge 1002, the controller end 2001 and the at least one of the controller edge portions 2002. By setting the heat dissipation structure 400, the heat dissipation performance is improved to ensure the normal operation of the mechanical assembly.

The heat dissipation structure 400 includes a plurality of heat dissipation ribs 410, taking the motor edge portion 1002 as an example, the two ends of the heat dissipation ribs are respectively flush with the two motor end portions 1001, and along the motor edge portion 1002 interval settings. Taking the motor end 1001 as an example, the cooling ribs are arranged at intervals along the radial direction of the motor end 1001 .

To sum up, the edge portion of the controller 2002 is attached to the edge portion of the motor 1002 at a ratio of not less than 50%, that is, the edge portion of the controller 2002 and the edge portion of the motor 1002 are not less than 50%. % of the overlapping portion, to prevent the controller edge portion 2002 from being protruded relative to the motor edge portion 1002, that is, to increase the radial dimension, and to increase the volume of the mechanical assembly. Therefore, this embodiment not only The motor unit 100 and the controller unit 200 are arranged compactly along the thickness direction to reduce the thickness and prevent the controller unit 200 from expanding radially along the motor unit 100, thus effectively reducing the mechanical assembly The overall volume makes the mechanical assembly suitable for different fields, thereby achieving standardization and universality.
