[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the related art, the flat wire stator of the motor and the three-phase wire of the electronic control are both hard copper bars. The flat wire stator of the motor is usually fixed to the motor housing by shrink fitting or bolts. There will be a rotational tolerance for assembly in the circumferential direction. The three-phase hard copper bar and sliding nut of the motor are wrapped together by plastic injection molding and then welded to the winding of the flat wire stator. There will be an X / Y / Z welding assembly tolerance in a total of 6 degrees of freedom. The three-phase hard copper bar of the electronic control is installed on the electronic control housing or other insulating components. There is an assembly tolerance here. When the three-phase hard copper bar of the electronic control is connected to the three-phase copper bar of the motor, there will also be an X / Y / Z assembly tolerance in a total of 6 degrees of freedom. The above multiple accumulated tolerances will make it difficult to align the mounting holes of the three-phase hard copper bar of the motor with the mounting holes of the three-phase hard copper bar of the electronic control, resulting in low motor assembly efficiency.

[0034] Reference below Figure 1-Figure 7 A stator assembly for a motor according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 7 As shown, the stator assembly according to the utility model includes: a stator body 10, a first hard copper bar 20, a fixing member and a conductive member, the first hard copper bar 20 is arranged on the stator body 10, the fixing member is arranged on the stator body 10 and / or the first hard copper bar 20, the fixing member is provided with a movable connecting member 40, the conductive member is suitable for being electrically connected to the electric control component, and the conductive member is provided with a first connecting portion 521; wherein the connecting member 40 moves to selectively cooperate with the first connecting portion 521 to fix the conductive member to the first hard copper bar 20.

[0036] In some embodiments, a fixing member is provided on the stator body 10, and a movable connecting member 40 is provided on the fixing member. The connecting member 40 can move relative to the fixing member in the horizontal direction and / or the height direction, that is, the connecting member 40 can move relative to the first hard copper bar 20 in the horizontal direction and / or the height direction; in other embodiments, a fixing member is provided on the first hard copper bar 20, and a movable connecting member 40 is provided on the fixing member, and the connecting member 40 can move relative to the first hard copper bar 20 in the horizontal direction and / or the height direction; in other embodiments, the fixing member is connected to the stator body 10 and the first hard copper bar 20 respectively, and the fixing member is provided with a connecting member 40 that can move relative to the first hard copper bar 20 in the horizontal direction and / or the height direction, which is not limited here.

[0037] It is worth noting that the stator body 10 includes: a stator core and a winding, the first hard copper bar 20 is suitable for being electrically connected to the winding, and the conductive part includes: a second hard copper bar 51 and a fastener 52, the second hard copper bar 51 is suitable for being electrically connected to the electronic control component, the fastener 52 can be connected to the second hard copper bar 51, or the second hard copper bar 51 is provided with a through hole 511, and at least part of the fastener 52 is passed through the through hole 511, which is not limited here.

[0038] It is understandable that in the motor production process, since the first hard copper bar and the second hard copper bar are made of harder materials, when the holes cannot be aligned, the first hard copper bar and the second hard copper bar cannot be connected by fasteners, resulting in low motor production efficiency; in other embodiments, in order to solve the above-mentioned problem that the holes cannot be aligned, the manufacturer replaces the first hard copper bar and / or the second hard copper bar with a soft copper bar. The soft copper bar is formed by stacking a plurality of metal copper sheets in the thickness direction, so that the soft copper bar can move relative to the stator body in the horizontal direction, axial direction and / or height direction, so that the holes of the two copper bars are aligned during the connection process to facilitate fastener fixation, but the cost of the soft copper bar is relatively high, which increases the production cost of the motor.

[0039] In the present application, a fixing part is provided on the stator body 10 and / or the first hard copper bar 20, and a movable connecting part 40 is provided on the fixing part. During the production process of the motor 1 and when assembly tolerance occurs, the connecting part 40 can be moved in the horizontal direction and / or the height direction relative to the first hard copper bar 20, so that the connecting part 40 can cooperate with the first connecting portion 521 of the conductive part, thereby fixing the conductive part and the first hard copper bar 20 and electrically connecting them.

[0040] It is worth noting that the connector 40 is movably arranged on the fixing part and can only eliminate the two tolerances in the X and Y directions. The tolerance in the Z direction is eliminated by controlling the matching strength between the connector 40 and the first connecting part 521, that is, when the matching strength between the connector 40 and the first connecting part 521 is strong, the first hard copper bar 20 and / or the conductive part can be deformed in the Z direction, so that the conductive part is fixed to the first hard copper bar 20 (the X direction is constructed as the height direction, the Z direction is constructed as the axial direction of the stator body 10, the Y direction is constructed as the horizontal direction, and the X direction, the Y direction and the Z direction are orthogonal to each other).

[0041] According to the stator assembly involved in the utility model, by arranging a fixing part on the stator body 10 and / or the first hard copper bar 20, and a movable connecting part 40 is arranged on the fixing part, the connecting part 40 moves and is suitable for cooperating with the first connecting part 521 to fix and electrically connect the conductive part to the first hard copper bar 20, thereby improving the connection efficiency between the first hard copper bar 20 and the conductive part, and solving the problem of difficulty in connecting the hard copper bar of the motor 1 and the electric control hard copper bar due to assembly tolerance, and at the same time, it can avoid the use of soft copper bars, thereby reducing the production cost of the motor 1.

[0042] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the fixing member includes: a mounting plate 30 and a connecting member 40, the mounting plate 30 is provided with a receiving groove 31 open toward the conductive member, the connecting member 40 is movably arranged in the receiving groove 31, and the connecting member 40 is provided with a second connecting portion 41 suitable for cooperating with the first connecting portion 521.

[0043] In some embodiments, one of the first connection portion 521 and the second connection portion 41 can be configured as a screw, and the other of the first connection portion 521 and the second connection portion 41 can be configured as a threaded hole, and the screw and the threaded hole are threadedly matched to fix the conductive member to the first hard copper busbar 20. For example, the first connection portion 521 can be configured as a nut, and the nut can be movably accommodated in the receiving groove 31. During the production process of the motor 1, the screw on the conductive member can make the nut move in the receiving groove 31, so that the threaded hole of the nut can be aligned with the screw. At this time, the screw can be threadedly matched with the threaded hole and fix the conductive member to the first hard copper busbar 20.

[0044] It is worth noting that the mounting plate 30 is constructed as an insulating part, such as a plastic part. A cylindrical hot rivet is provided on one side of the mounting plate 30 facing the first hard copper bus 20 in the thickness direction, and the mounting plate 30 is fixed to the first hard copper bus 20 by the cylindrical hot rivet.

[0045] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, at least a portion of the outer circumferential wall of the connecting member 40 abuts against at least a portion of the inner circumferential wall of the accommodating groove 31 in the circumferential direction to limit the rotation of the connecting member 40 in the circumferential direction.

[0046] In some embodiments, the first connecting portion 521 is configured as a screw, the second connecting portion 41 is configured as a threaded hole, the cross-section of the accommodating groove 31 can be configured as a square, and the cross-section of the connecting member 40 is configured as a square. The connecting member 40 can move in the accommodating groove 31 relative to the mounting plate 30, but when the connecting member 40 has a tendency to rotate relative to the accommodating groove 31, the outer peripheral wall of the connecting member 40 and the inner peripheral wall of the accommodating groove 31 stop to prevent the connecting member 40 from rotating, thereby preventing the connecting member 40 from rotating when the screw and the threaded hole are engaged, causing the screw to be unable to engage with the threaded hole, thereby improving the engagement efficiency of the screw and the threaded hole, thereby improving the assembly efficiency of the motor 1.

[0047] In other embodiments, the cross-section of the connecting member 40 is constructed as a triangle, a pentagon or other polygons, and the connecting member 40 can move in the receiving groove 31 relative to the mounting plate 30. However, when the connecting member 40 has a tendency to rotate relative to the receiving groove 31, the outer peripheral wall of the connecting member 40 and the inner peripheral wall of the receiving groove 31 stop the connecting member 40 from rotating.

[0048] In some other embodiments, the cross-section of the connecting member 40 can be constructed into any shape, but the outer peripheral wall of the connecting member 40 is provided with at least one limit block, which is suitable for stopping against the inner wall of the accommodating groove 31 when the connecting member 40 rotates in the accommodating groove 31 relative to the mounting plate 30, thereby preventing the connecting member 40 from rotating in the accommodating groove 31. No limitation is made here.

[0049] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the first hard copper busbar 20 is disposed between the connecting member 40 and the conductive member. The first hard copper busbar 20 is provided with a connecting hole 221 penetrating in the thickness direction. The projection of the second connecting portion 41 in the thickness direction is located in the connecting hole 221 .

[0050] In some embodiments, the free end of the first connection portion 521 or the second connection portion 41 can pass through the connecting hole 221 of the first hard copper bus 20 and the through hole 511 of the second hard copper bus 51 and be connected to the second connection portion 41 or the first connection portion 521. In the projection in the thickness direction, the projection of the second connection portion 41 is located in the connecting hole 221 to prevent the inner wall of the connecting hole 221 from restricting the movement of the first connection portion 521 or the second connection portion 41 in the horizontal direction or the height direction. Therefore, when the first hard copper bus 20 is fixed, the second connection portion 41 can move in the horizontal direction or the height direction relative to the first hard copper bus 20, so that the second connection portion 41 can be aligned and matched with the first connection portion 521 to fix the first hard copper bus 20 and the second hard copper bus 51.

[0051] According to some embodiments of the present invention, Figure 1-Figure 7As shown, the inner circumferential wall of the connecting hole 221 is formed with a plurality of notches extending radially away from the connecting hole 221, and the plurality of notches are spaced apart in the circumferential direction of the connecting hole 221; wherein the first connecting portion 521 or the second connecting portion 41 can selectively move in the connecting hole 221 and / or the plurality of notches.

[0052] It is understandable that the first connection part 521 and / or the second connection part 41 can be selectively moved in the connecting hole 221 and / or the plurality of notches so that the first connection part 521 can be aligned with the second connection part 41, so that the first connection part 521 can cooperate with the second connection part 41. At the same time, compared with the solution of opening a large through hole on the first hard copper bar 20, the opening area of ​​the first hard copper bar 20 of the present application is small, which improves the structural strength of the first hard copper bar 20. At the same time, opening a large through hole on the first hard copper bar 20 may cause the connector 40 to fall out of the receiving groove 31 through the large through hole, resulting in a decrease in the connection efficiency between the first hard copper bar 20 and the second hard copper bar 51.

[0053] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the multiple gaps include: a first gap, a second gap, a third gap and a fourth gap. The first gap and the second gap are respectively arranged on both sides of the connecting hole 221 in the height direction, and the third gap and the fourth gap are respectively arranged on both sides of the connecting hole 221 in the horizontal direction.

[0054] It can be understood that the first notch and the second notch are respectively arranged on both sides of the connecting hole 221 in the height direction. Therefore, the first notch and the second notch increase the length dimension of the connecting hole 221 in the height direction, so that the first connecting part 521 or the second connecting part 41 can move in the height direction relative to the first hard copper bar 20 when the first hard copper bar 20 is fixed, thereby eliminating the assembly tolerance in the height direction (X direction) when the first hard copper bar 20 and the second hard copper bar 51 are assembled.

[0055] The third notch and the fourth notch are respectively arranged on both sides of the connecting hole 221 in the horizontal direction, that is, the third notch and the fourth notch can increase the length dimension of the connecting hole 221 in the horizontal direction, so that the first connecting part 521 or the second connecting part 41 can move in the horizontal direction relative to the first hard copper bar 20 when fixed with the first hard copper bar 20, thereby eliminating the assembly tolerance in the horizontal direction (Y direction) when the first hard copper bar 20 and the second hard copper bar 51 are assembled.

[0056] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the diameter of the free end of the first connection portion 521 gradually increases in the direction away from the second connection portion 41 ; and / or the diameter of the free end of the second connection portion 41 gradually decreases in the direction away from the first connection portion 521 .

[0057] In some embodiments, the first connection portion 521 is configured as a screw, and the second connection portion 41 is configured as a threaded hole, and the diameter of the free end of the first connection portion 521 gradually increases in the direction away from the second connection portion 41, thereby, the free end of the screw can form a guide portion to facilitate the cooperation between the screw and the threaded hole; in other embodiments, the diameter of the free end of the second connection portion 41 gradually decreases in the direction away from the first connection portion 521, thereby, the free end of the nut can form a guide portion to facilitate the cooperation between the screw and the threaded hole; in other embodiments, the diameter of the free end of the first connection portion 521 gradually increases in the direction away from the second connection portion 41, and the diameter of the free end of the second connection portion 41 gradually decreases in the direction away from the first connection portion 521, thereby, the free end of the screw can form a guide portion, and the free end of the nut can also form a guide portion, which further facilitates the cooperation between the screw and the threaded hole.

[0058] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the first hard copper bar 20 is constructed in multiple numbers, and the distances between the connecting holes 221 of the multiple first hard copper bars 20 and the center of the stator body 10 are equal. In some embodiments, the first hard copper bar 20 is constructed in three numbers, and the three first hard copper bars 20 are electrically connected to the winding lead wires respectively, and the distances between the connecting holes 221 of the three first hard copper bars 20 and the center of the stator body 10 are equal. Therefore, the connection lines between the three first hard copper bars 20 are located on the circumferential surface co-centered with the stator body 10, which facilitates the layout of the first hard copper bars 20.

[0059] According to some embodiments of the present invention, Figure 1-Figure 7 As shown, the first hard copper busbar 20 includes: a first split portion 21 and a second split portion 22, wherein the first split portion 21 extends axially away from the stator body 10, and one end of the first split portion 21 is connected to the stator body 10; the second split portion 22 is arranged at the other end of the first split portion 21 and extends radially away from the center of the stator body 10; wherein at least part of the outer surface of the mounting plate 30 is connected to the first split portion 21 and / or the second split portion 22.

[0060] It can be understood that the first split part 21 extends in the axial direction (Z direction), one end of the first split part 21 is connected to the winding and electrically connected, and the other end of the first split part 21 is connected to the second split part 22, and the second split part 22 extends away from the center of the stator core in the height direction (X direction).

[0061] In some embodiments, the mounting plate 30 is disposed between the first split portion 21, the second split portion 22 and the stator core, the surface of the first split portion 21 facing the second split portion 22 is configured as a first connecting surface, the surface of the mounting plate 30 facing the first split portion 21 is configured as a second connecting surface, cylindrical hot rivets are provided on the second connecting surface, and the first connecting surface and the second connecting surface are connected and fixed by the cylindrical hot rivets.
