Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

First embodiment

As shown in fig. 1 and 2, the mechanical assembly of the motor and the controller includes:

a motor unit 100, said motor unit 100 having two parallel and generally circular motor ends 1001 and a motor rim portion 1002 extending between said two motor ends 1001, said two motor ends 1001 defining said motor unit thickness a therebetween;

a controller unit 200, said controller unit 200 having two parallel controller end portions 2001 and a controller edge portion 2002 extending between said two controller end portions 2001, said controller unit thickness b being defined between said two controller end portions 2001, said controller unit 200 being mounted on said motor end portion 1001 in such a manner that said controller end portion 2001 is parallel to said motor end portion 1001, and said controller edge portion 2002 being fitted to correspond to said motor edge portion 1002 in 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 is disposed in contact with the motor end 100 as much as possible, so that the sum of the motor unit thickness a and the controller unit thickness b, which forms the entire thickness of the mechanical assembly, and the motor unit 100 and the controller unit 200 are closely arranged in the thickness direction, which reduces the thickness of the mechanical assembly, further reducing the entire volume.

In addition, the controller edge portion 2002 is attached to the motor edge portion 1002 in a ratio of not less than 50%, that is, there is an overlapping portion of not less than 50% between the controller edge portion 2002 and the motor edge portion 1002, so that the controller edge portion 2002 is prevented from being arranged in a protruding manner relative to the motor edge portion 1002, that is, the radial dimension is increased, and the problem of increasing the volume of the mechanical assembly occurs.

As shown in fig. 1, the controller edge portion 2002 is not in contact with the motor edge portion 1002, and is retained in the area surrounded by the motor edge portion 1002. It can be seen that the controller edge 2002 and the motor edge 1002 are not attached to each other, and are recessed toward the inside of the controller edge 2002, so that compared with the cylindrical motor unit 100, the volume of the controller unit 200 is further reduced, and the volume of the mechanical assembly is further reduced.

As shown in fig. 1 to 3, the motor unit 100 further includes a plurality of connecting rib assemblies 110, the plurality of connecting rib assemblies 110 extend outward from the motor edge portion 1002 and are spaced apart from each other along the motor edge portion 1002, the controller unit 200 further includes a plurality of connecting lugs 211, the plurality of connecting lugs 211 extend outward from the controller edge portion 2002 and are spaced apart from each other along the controller edge portion 2002, the connecting lugs 211 can be opposite to the connecting rib assemblies 110 and are fixed by a first fastening member 310, and the first fastening member 310 is hidden in the connecting lugs 211 and the connecting rib assemblies 110.

Specifically, the tie bar assembly 110 extends in the motor unit thickness a direction, and both ends are flush with the two motor ends 1001, respectively, and a plurality of the tie bar assemblies 110 are arranged at equal intervals. The connecting rib assembly 110 is further provided with a threaded hole for screwing with the first fastener 310, that is, when the connecting lug 211 is opposite to the connecting rib assembly 110, the first fastener 310 penetrates through the connecting lug 211 and is screwed with the threaded hole in the connecting rib assembly 110, so that the controller unit 200 is fixed on one end 1001 of the motor unit 100 by pulling. A plurality of the engaging lugs 211 are also provided at equal intervals along the controller edge portion 2002. It can be seen that the connection points of the connection between the controller unit 200 and the motor unit 100 via the first fastening members 310 are uniformly arranged, so as to improve the connection strength between the controller unit and the motor unit.

More specifically, the connection rib assembly 110 has a substantially circular cross section, and the radian of the circular cross section is not less than 180 °, wherein the connection rib assembly 110 not only serves to screw the first fastening member 310 to draw and fix the controller unit 200, but also improves the strength of the housing of the motor unit 100. Relative to the connecting rib assembly 110, the motor edge portion 1002 only partially extends outwards, so that the defect that the whole volume is enlarged due to the fact that the motor edge portion extends outwards completely is avoided.

Preferably, the first fastening member 310 is hidden in the connecting lug 211 and the connecting rib assembly 110, which not only provides an aesthetic function, but also prevents the first fastening member 310 from being damaged due to exposure, thereby affecting the connecting effect thereof.

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

The distance between two adjacent connector rib assemblies 110 is shown as 1/2 of the distance between two adjacent connector ears 211. And the number of the tie bar assemblies 110 is 2 times the number of the tie ears 211.

As shown in fig. 1 to 3, the controller unit 200 includes two controller housings 220 arranged and assembled along a thickness b of the controller unit, and a plurality of connection nodes 212 disposed at a controller edge portion 2002 and pulling and connecting the two controller housings 220, wherein the connection nodes 212 are arranged in a staggered manner from the connection lugs 211 and can be opposite to the connection rib assembly 110.

The connection node 212 is staggered from the connection lug 211 so as to fix the first fastening member 310 to the connection lug 211 and the connection rib assembly 100. Wherein a plurality of the connection nodes 212 are disposed at equal intervals along the controller edge portion 2002, wherein a distance between two adjacent connection nodes 212 is equal to a distance between two adjacent connection ears 211, which is twice a distance between two adjacent connection rib assemblies 100. It can be seen that the sum of the number of the connection nodes 212 and the number of the connection lugs 211 is equal to the number of the connector bar assemblies 100.

As shown in fig. 2 to 5, the connection node 212 includes connection plates 2121 respectively disposed on the two controller housings 220, and a second fastener 320 pulling and connecting the two connection plates, and the second fastener 320 is hidden in the two connection plates 2121.

The second fastening member 320 is hidden, so that the appearance is improved, and the damage caused by the exposure of the second fastening member 320 is prevented, thereby affecting the connection effect. When the two controller cases 220 are assembled, the two connecting plates 2121 thereof abut and are held at the intermediate position of the controller unit thickness b, and the engaging lug 211 is held on the controller edge portion 2002 so as to be close to the motor unit 100. So that the engaging lug 211 can approach the connecting rib assembly 110 to further prevent the first fastening member 310 from being exposed.

The connecting lug 211 is thin and is used for hooking the head of the first fastening member 310, and the first fastening member 310 and the second fastening member 320 may be bolts or the like. The thickness of the connecting plate 2121 located at different positions of the controller housing 220 may be different, that is, the connecting plate 2121 located near the motor unit 100 has a thinner thickness for hooking the head of the second fastening member 320, and the connecting plate 2121 located far from the motor unit 100 has a thicker thickness for being screwed with the second fastening member 320.

As shown in fig. 1 and 2, the motor unit 100 includes two motor housings 120, a plurality of connecting ribs 111 are disposed at equal intervals on the circumference of each of the motor housings 120, when the two motor housings 120 are arranged and assembled along the thickness a of the motor unit, the connecting ribs 111 on the two motor housings 120 correspond to each other one by one and form the connecting rib assembly 110, and a third fastening member for fastening the two motor housings 120 is hidden in the connecting rib assembly 110, and the third fastening member may be a bolt or the like.

Taking the example that the third fastening member is hidden by the tie bar assembly 110, a connection channel respectively matching with the first fastening member 310 and the third fastening member is formed in the tie bar assembly 110, and the connection channel may be sequentially divided into a countersink portion, a threaded portion and a through hole portion, and the countersink portion and the threaded hole portion may be located in two different and opposite tie bars 111, so that the third fastening member passes through the countersink portion and is screwed with the threaded hole, so as to realize the assembling and fixing of the two motor housings 120. Wherein the head of the third fastener may be embedded in the countersink portion and the first fastener 310 is threadedly coupled to the tie-bar assembly 110 using the threaded hole.

Further, in two adjacent connecting rib assemblies 110, the countersunk portion, the threaded portion and the through hole portion of the connecting channel of one of the connecting rib assemblies 110 are arranged from left to right, and in the connecting channel of the other connecting rib assembly 110, the countersunk portion, the threaded portion and the through hole portion are arranged from right to left, so that the plurality of third fasteners are sequentially matched with the connecting channel from the left side and the right side of the motor unit.

As shown in fig. 2, the diameter of the motor end 1001 is larger than the motor unit thickness a, so that the motor 100 is formed as a disk motor. By adopting the disc type motor, the size of the thickness a of the motor unit is reduced, and the miniaturization design of the mechanical assembly is further realized.

As shown in fig. 1 to 3, the mechanical assembly further has a heat dissipation structure 400, and the heat dissipation structure 400 is disposed at least one of the motor end 1001, the motor edge 1002, the controller end 2001, and the controller edge 2002. Through setting up heat radiation structure 400, promote heat dispersion to guarantee the normal operating of mechanical assembly.

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

In summary, the controller edge portion 2002 is attached to the motor edge portion 1002 at a ratio not less than 50%, that is, there is an overlapping portion not less than 50% between the controller edge portion 2002 and the motor edge portion 1002, so that the controller edge portion 2002 is prevented from being protruded relative to the motor edge portion 1002, that is, the radial dimension is increased, and the problem of increasing the volume of the mechanical assembly occurs, and therefore, in this embodiment, the motor unit 100 and the controller unit 200 are not only arranged compactly along the thickness direction to reduce the thickness, but also the controller unit 200 is prevented from being enlarged radially along the motor unit 100, and therefore, the overall volume of the mechanical assembly is effectively reduced, so that the mechanical assembly is applicable to different fields, and further standardization and universality are achieved.
