[0001] The present invention relates to the technical field of motors, and in particular to a bus, a motor, a water pump and a vehicle. Background Art

[0002] Currently, the busbar includes a frame and a plurality of busbars arranged on the frame. During the assembly process of the busbar and the frame, the assembly accuracy of the busbar is difficult to control, and the position stability of the busbar relative to the frame is poor. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention is to provide a busbar.

[0005] A second aspect of the present invention is to provide an electric motor.

[0006] A third aspect of the present invention is to provide a water pump.

[0007] A fourth aspect of the present invention provides a vehicle.

[0008] In view of this, according to a first aspect of the present invention, a bus is provided for a motor, the bus comprising a frame, an assembly groove, a partition, a notch and a bus bar, the assembly groove being arranged on the frame; the partition being connected to the frame and being located in the assembly groove, the partition dividing the assembly groove into a first assembly groove and a second assembly groove; the notch being arranged on the partition to connect the first assembly groove with the second assembly groove; part of the bus bar being arranged in the first assembly groove, and another part of the bus bar extending into the second assembly groove through the notch.

[0009] The busbar provided by the present invention includes a skeleton, an assembly groove, a separator, a notch and a busbar, wherein the skeleton is used to provide support for the busbar and isolate adjacent busbars among at least three busbars to play the role of electrical insulation. The skeleton is provided with an assembly groove, the separator is connected to the skeleton and is located in the assembly groove, the separator is annular, and the separator divides the assembly groove into a first assembly groove and a second assembly groove along the radial direction of the skeleton, wherein the first assembly groove is an outer annular groove, and the second assembly groove is an inner annular groove. It is worth noting that the skeleton and the separator are both insulating parts, the skeleton is annular, and the skeleton and the separator can be molded by injection molding. Among them, the notch is opened on the separator, that is, part of the separator is recessed along the axial direction to form a notch. The number of busbars is at least three. Part of each busbar is arranged in the first assembly groove, and the other part of the busbar will pass through the notch and extend into the second assembly groove, that is, one busbar is located in the first assembly groove and the second assembly groove at the same time. The present invention allows part of the busbar to be located in the first assembly groove, and the other part of the busbar to be located in the second assembly groove through the gap. On the one hand, the gap can facilitate the accurate positioning and assembly of the busbar on the skeleton, which is easy to operate; on the other hand, when the busbar is assembled in the first assembly groove, the second assembly groove and the gap, the groove walls of the first assembly groove and the second assembly groove fit with the busbar, thereby limiting the movement of the busbar in the radial direction of the skeleton. At the same time, part of the busbar located in the gap can also be blocked by the partition to a certain extent to avoid the movement of the busbar in the circumferential direction, thereby ensuring the position stability of the busbar and avoiding the short circuit caused by the contact between adjacent busbars due to the loose position of the busbar. Specifically, the busbar is a conductor, and the busbar is used to connect the winding ends that need to be connected together in multiple windings of the motor stator, thereby realizing the electrical connection of multiple winding ends and realizing the bus function. Specifically, the number of busbars is at least three, including a U-phase busbar, a V-phase busbar, and a W-phase busbar, that is, the shapes and sizes of the U-phase busbar, the V-phase busbar, and the W-phase busbar are completely consistent. Furthermore, the busbar is made of copper, which has good electrical conductivity and is relatively cheap. In addition, copper has the advantages of being easy to stamp and having sufficient hardness.

[0010] In a possible design, further, the number of the notches is at least three, and the at least three notches divide the partition into at least three partition segments.

[0011] In this design, the number of notches is at least three, and at least three notches divide the partition into at least three partition sections. The number of busbars is at least three, and the number of busbars corresponds to the number of notches in a one-to-one manner. A busbar passes through a notch so that a portion of the busbar is located in the first assembly groove, and another portion of the busbar is located in the second assembly groove. The number of notches is three, and the three notches include a first notch, a second notch, and a third notch, and the three busbars include a first busbar, a second busbar, and a third busbar. Then the first busbar passes through the first notch so that a portion of it is located in the first assembly groove, and another portion is located in the second assembly groove. Similarly, the second busbar passes through the second notch so that a portion of it is located in the first assembly groove, and another portion is located in the second assembly groove. The third busbar passes through the third notch so that a portion of it is located in the first assembly groove, and another portion is located in the second assembly groove.

[0012] In a possible design, further, the busbar further includes a limiting member, which is arranged on the groove wall of the assembly groove and / or each of the at least three partitioning segments to limit the axial movement of the busbar along the motor.

[0013] In this design, a stopper is provided on the groove wall of the assembly groove, and / or a stopper is also provided on each partition. When the busbar is arranged in the assembly groove, the stopper can limit the axial movement of the busbar. Further, the stopper has a guide surface. When the busbar is inserted into the assembly groove along the axial direction, the busbar can extend into the bottom of the assembly groove along the guide surface. When the busbar is assembled in place, the busbar is clamped between the stopper and the groove bottom of the assembly groove, ensuring the position stability of the busbar in the axial direction.

[0014] In a possible design, further, the limiting member includes a first limiting member connected to the groove wall of the first assembly groove; and / or a second limiting member connected to the groove wall of the second assembly groove.

[0015] In this design, the first stopper is connected to the groove wall of the first assembly groove, and the second stopper is connected to the groove wall of the second assembly groove. Through the joint action of the first stopper and the second stopper, the same busbar can be effectively limited, thereby ensuring the position stability of the busbar. Specifically, when the first busbar passes through the first notch and is located in the first assembly groove and the second assembly groove respectively, the first stopper can limit the first part of the first busbar, and the second stopper can limit the second part of the first busbar, so that the first busbar as a whole can be constrained by the stopper, thereby achieving the axial position stability of the first busbar.

[0016] In a possible design, further, at least three notches are evenly arranged on the partition around the central axis of the skeleton.

[0017] In this design, at least three notches are evenly arranged on the partition around the central axis of the frame, so that at least three busbars with the same structure can be assembled on the frame. Different busbars are arranged on both sides of the same partition. For example, at least three partitions include a first partition, a first assembly groove corresponding to the first partition is provided with the head end of the first busbar, and a second assembly groove corresponding to the first partition is provided with the tail end of the second busbar adjacent to the first busbar.

[0018] In a possible design, further, the busbar also includes a supporting portion, which is connected to the outer side wall of the frame and extends in a direction away from the central axis of the frame, and the supporting portion is used to assemble the connection terminals of the motor.

[0019] In this design, a support portion is provided on the outer side wall of the frame, the support portion extends away from the central axis of the frame, and the support portion is used to assemble the wiring terminals of the motor. By providing the support portion, the installation and positioning of the wiring terminals can be facilitated. Furthermore, the support portion and the frame can be prepared by injection molding, with high connection strength and simple preparation process. Furthermore, the number of support portions and the number of wiring terminals are multiple, corresponding to each other.

[0020] In a possible design, further, the busbar also includes a mounting opening, the mounting opening is arranged on the supporting portion, and the wiring terminal is inserted into the mounting opening.

[0021] In this design, a mounting opening is also provided on the support portion, and the mounting opening is used to assemble the wiring terminal, so that the wiring terminal is inserted into the mounting opening, which reduces the difficulty of assembling the wiring terminal and improves the assembly accuracy of the wiring terminal, preventing the wiring terminal from being assembled with deviations and unable to connect with other parts of the motor (such as the controller and the mounting part of the bus).

[0022] In a possible design, further, the support portion includes a first support segment and a second support segment connected to each other, the first support segment is located between the skeleton and the second support segment, the mounting port is arranged on the first support segment, and the axial thickness of the first support segment is greater than the axial thickness of the second support segment.

[0023] In this design, the support portion includes a first support segment and a second support segment that are connected. The first support segment is connected to the frame, and the mounting port is provided on the first support segment. The axial thickness of the first support segment is greater than the axial thickness of the second support segment, so that the first support segment can provide reliable support for the terminal block. The axial thickness of the second support segment that is not used for assembling the terminal block is smaller, which can also reduce costs to a certain extent and avoid unnecessary waste of materials.

[0024] In a possible design, further, the busbar also includes an extension portion, which is connected to the outer wall of the frame away from the supporting portion, and extends in a direction away from the central axis of the frame, and is used to connect to the stator frame of the motor.

[0025] In this design, the busbar also includes an extension portion, which avoids the support portion and is connected to the outer side wall of the frame, and the extension portion extends in a direction away from the central axis of the frame, thereby facilitating the matching connection between the extension portion and the stator frame of the motor. Specifically, there are multiple extension portions, and the multiple extension portions are arranged on the frame at intervals. Specifically, the extension portion and the frame are an integrated structure, that is, they can be made by an injection molding process.

[0026] In a possible design, further, the busbar includes a main body, which is embedded in the assembly groove; the main body includes a first main section, a second main section and a bent section, and the first main section is located in the first assembly groove; the distance between any point on the second main section and the central axis of the motor is smaller than the distance between any point on the first main section and the central axis of the motor, and the second main section is located in the second assembly groove; the bent section is connected between the first main section and the second main section, and the bent section is arranged in the notch.

[0027] In this design, the main body is divided into a first main body section, a second main body section and a bending section, wherein the distance between any point on the first main body section and the central axis of the motor is greater than the distance between any point on the second main body section and the central axis of the motor, that is, the distances between the first main body section and the second main body section and the central axis are not equal. At this time, the first main body section and the second main body section are connected by the bending section. When there are multiple bus bars in the bus bar, the first main body section and the second main body section with different radial sizes can facilitate the arrangement of multiple bus bars of the same structure on the skeleton. The first main body section is located in the first assembly groove, the bending section is located in the notch, and the second main body section is located in the second assembly groove. Specifically, the first main body section is a first arc section, and the second main body section is a second arc section. The first arc section and the second arc section have the same center, and the radius of the first arc section is greater than the radius of the second arc section, that is, the first arc section and the second arc section are concentric but have different diameters. The first arc section and the second arc section are not complete rings, and the first arc section and the second arc section can be formed by bending or the like.

[0028] Further, on a plane perpendicular to the axis of the skeleton, the main body of all the busbars can form two incomplete circular rings. Specifically, the first main body section in the main body of all the busbars can form an incomplete first circular ring, and the second main body section in the main body of all the busbars can form an incomplete second circular ring, wherein the radius of the first circular ring is greater than the radius of the second circular ring.

[0029] In a possible design, further, the number of bus bars is at least three, and the structures of any two of the at least three bus bars are the same; the at least three bus bars include adjacent first bus bars and second bus bars, and the first main section of the first bus bar is located on the side of the second main section of the second bus bar that is away from the central axis of the motor.

[0030] In this design, at least three busbars include a first busbar and a second adjacent busbar, wherein the main body includes a first side close to the central axis of the motor and a second side away from the central axis of the motor. The connection method of the two adjacent busbars is as follows: the first main body section of the first busbar is located on the second side of the second main body section of the second busbar, that is, any two adjacent busbars among the at least three busbars satisfy the above arrangement method. Therefore, when multiple busbars with the same structure are arranged, interference between the busbars will be avoided according to this arrangement method. In addition, according to this arrangement method, the density of the busbars can be improved, and the size of the product can be further reduced.

[0031] In a possible design, the busbar further includes: a connecting portion, which is arranged at the end of the main body and protrudes from the outer wall of the skeleton, and the connecting portion is used to connect the winding of the motor; the connecting portion includes: a first connecting portion, which is arranged on the first main body segment; and a second connecting portion, which is arranged on the second main body segment.

[0032] In this design, the busbar also includes a connecting portion arranged on the main body, through which the winding ends of the multiple windings of the motor stator can be connected, and the good electrical conductivity of the busbar is used to achieve electrical connection of the corresponding winding ends without directly connecting the corresponding winding terminals, thereby reducing the difficulty of wiring, facilitating efficient and fast operation of the production line, and helping to improve the production efficiency of the product. Specifically, the main body includes two ends, namely the free end of the first main body segment and the free end of the second main body segment, and the connecting portion includes a first connecting portion and a second connecting portion, the first connecting portion is arranged on the first main body segment, and the second connecting portion is arranged on the second main body segment, that is, the distance between the second connecting portion and the central axis of the motor is less than the distance between the first connecting portion and the central axis, so that the radial extension length of the second connecting portion is greater than the radial extension length of the first connecting portion, which can ensure that the wall surfaces of the first connecting portion and the second connecting portion that are away from the central axis are within the same arc surface, thereby facilitating the connection between the winding and the connecting portion.

[0033] In a possible design, the bus further includes a first mating groove and a second mating groove, the first mating groove is opened on the frame corresponding to the first connecting part; the second mating groove is opened on the frame and the partition corresponding to the second connecting part and passes through the frame radially.

[0034] In this design, when the busbar is assembled on the skeleton, the first connection part is clamped in the first matching groove, and the second connection part is clamped in the second matching groove. The first connection part can be clamped on the groove wall of the first matching groove, and the second connection part can be clamped on the groove wall of the second matching groove, thereby limiting the circumferential movement of the busbar. Specifically, the number of first connection parts corresponds to the number of first matching grooves, and the number of second connection parts corresponds to the number of second matching grooves. Specifically, the number of first connection parts is two, and the number of second connection parts is two. It is worth noting that since the second connection part is arranged on the second main body section of the main body, and the second main body section is located in the second assembly groove, the second connection part needs to contact the partition and the skeleton. Therefore, the second matching groove radially penetrates the partition and the skeleton.

[0035] In a possible design, the busbar further includes: a mounting portion, which is arranged on the main body avoiding the connecting portion, and the mounting portion is used to connect the wiring terminal.

[0036] In this design, the busbar also includes a mounting portion, which is arranged on the main body away from the connecting portion. The mounting portion is used to connect the wiring terminals of the motor. A mounting portion for connecting the wiring terminals is separately provided to ensure that the connection position of the wiring terminals is accurate. Specifically, the number of mounting portions is 3. The 3 mounting portions are arranged on the main body at intervals. A suitable mounting portion is selected for connection according to the position of the wiring terminals in the motor. That is, not every mounting portion among the multiple mounting portions is used to connect the wiring terminals.

[0037] In a possible design, further, the mounting portion includes a first mounting portion and a second mounting portion, the first mounting portion is connected to the first main body section of the main body; the second mounting portion is connected to the second main body section of the main body.

[0038] In this design, the mounting portion includes a first mounting portion and a second mounting portion, the first mounting portion is connected to the first main body section, and the second mounting portion is connected to the second main body section, that is, the distance between the first mounting portion and the central axis is greater than the distance between the second mounting portion and the central axis. In order to make the outer wall surfaces of the first mounting portion and the second mounting portion located in the same arc surface, the extension length of the first mounting portion in the first direction can be made smaller than the extension length of the second mounting portion in the first direction. At this time, the mounting surfaces on the first mounting portion and the second mounting portion for connecting with the wiring terminal are both located in the same arc surface, thereby facilitating the assembly of the wiring terminal. Specifically, the number of the first mounting portions is two, and the number of the second mounting portions is one.

[0039] In a possible design, the bus further includes a first mounting groove and a second mounting groove, the first mounting groove is opened on the frame corresponding to the first mounting portion; the second mounting groove corresponds to the second mounting portion and is arranged on the frame and the partition along the radial direction of the frame.

[0040] In this design, when the busbar is assembled on the skeleton, the first mounting portion is clamped in the first mounting groove, and the second mounting portion is clamped in the second mounting groove. The first mounting portion can be clamped on the groove wall of the first mounting groove, and the second mounting portion can be clamped on the groove wall of the second mounting groove, thereby limiting the circumferential movement of the busbar. Specifically, the number of first mounting portions corresponds to the number of first mounting grooves, and the number of second mounting portions corresponds to the number of second mounting grooves. Specifically, the number of first mounting portions is two, and the number of second mounting portions is one. It is worth noting that since the second mounting portion is arranged on the second main body section of the main body, and the second main body section is located in the second assembly groove, the second mounting portion needs to contact the partition and the skeleton. Therefore, the second mounting groove radially penetrates the partition and the skeleton.

[0041] In a possible design, further, projections of the support portion of the busbar, the extension portion of the busbar, the connection portion and the mounting portion on the axial end surface of the frame do not overlap with each other.

[0042] In this design, the projections of the support part, extension part, connection part and mounting part of the busbar on the axial end face of the skeleton do not overlap with each other. When the extension part is connected to the stator frame, when the mounting part is connected to the terminal, and when the connection part is connected to the winding, there will be no interference with each other, thereby reducing the difficulty of assembly.

[0043] According to a second aspect of the present invention, there is provided a motor comprising a busbar provided by any one of the above designs.

[0044] The motor provided by the present invention includes a casing, and the motor also includes a bus described in any of the above technical solutions. The bus is arranged in the casing. Therefore, the motor has all the beneficial effects of the bus, which will not be repeated here.

[0045] In a possible design, the motor further includes a stator frame, one end of the stator frame is connected to one side of the busbar in the axial direction, and the stator frame has a winding, which is connected to a connecting portion of the busbar.

[0046] In a possible design, the motor further includes a control component, which is arranged on the other side of the bus along the axial direction, and the control component has a controller; the wiring terminal is assembled on the support portion of the bus and electrically connects the mounting portion of the bus with the controller.

[0080] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0081] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0082] Refer to the following Figures 1 to 16 A busbar 1 , a motor 3 , a water pump 4 and a vehicle 5 according to some embodiments of the present invention are described.

[0083] Embodiment 1

[0084] According to a first aspect of the present invention, there is provided a busbar 1 for use in a motor 3, such as Figure 1 , Figure 5 and Figure 6 As shown, the busbar 1 includes a frame 10, an assembly groove 101, a separator 11, a notch 111 and a busbar 20, wherein the assembly groove 101 is arranged on the frame 10; the separator 11 is connected to the frame 10 and is located in the assembly groove 101, and the separator 11 divides the assembly groove 101 into a first assembly groove 101a and a second assembly groove 101b; the notch 111 is arranged on the separator 11 to connect the first assembly groove 101a with the second assembly groove 101b; part of the busbar 20 is arranged in the first assembly groove 101a, and another part of the busbar 20 passes through the notch 111 and extends into the second assembly groove 101b.

[0085] The busbar 1 provided by the present invention comprises a skeleton 10, an assembly groove 101, a separator 11, a notch 111 and a busbar 20, wherein the skeleton 10 is used to provide support for the busbar 20 and isolate adjacent busbars 20 among at least three busbars 20, thereby playing the role of electrical insulation. The skeleton 10 is provided with an assembly groove 101, the separator 11 is connected to the skeleton 10 and is located in the assembly groove 101, the separator 11 is annular, and the separator 11 divides the assembly groove 101 into a first assembly groove 101a and a second assembly groove 101b along the radial direction of the skeleton 10, wherein the first assembly groove 101a is an outer annular groove, and the second assembly groove 101b is an inner annular groove. It is worth noting that the skeleton 10 and the separator 11 are both insulating parts, the skeleton 10 is annular, and the skeleton 10 and the separator 11 can be molded by injection molding. Among them, the notch 111 is opened on the separator 11, that is, part of the separator 11 is recessed along the axial direction to form the notch 111. There are at least three busbars 20. Part of each busbar 20 is disposed in the first assembly groove 101a, and another part of the busbar 20 passes through the notch 111 and extends into the second assembly groove 101b, that is, one busbar 20 is located in both the first assembly groove 101a and the second assembly groove 101b. The present invention allows part of the busbar 20 to be located in the first assembly groove 101a, and the other part of the busbar 20 to be located in the second assembly groove 101b through the notch 111. On the one hand, the notch 111 can facilitate the precise positioning and assembly of the busbar 20 on the skeleton 10, which is easy to operate; on the other hand, when the busbar 20 is assembled in the first assembly groove 101a, the second assembly groove 101b and the notch 111, the groove walls of the first assembly groove 101a and the second assembly groove 101b fit with the busbar 20, thereby limiting the radial movement of the busbar 20 in the skeleton 10. At the same time, the part of the busbar 20 located in the notch 111 can also be blocked by the partition 11 to avoid the circumferential movement of the busbar 20 to a certain extent, thereby ensuring the position stability of the busbar 20 and avoiding the short circuit caused by the contact between adjacent busbars 20 due to the loose position of the busbar 20. Specifically, the busbar 20 is a conductor, and the busbar 20 is used to connect the ends of the windings 31a that need to be connected together among the multiple windings 31a of the stator of the motor 3, thereby realizing the electrical connection of the ends of the multiple windings 31a and realizing the bus function. Specifically, the number of busbars 20 is at least three, including U-phase busbar 20, V-phase busbar 20 and W-phase busbar 20, that is, the shapes and sizes of U-phase busbar 20, V-phase busbar 20 and W-phase busbar 20 are completely consistent. Furthermore, the material of the busbar 20 is copper, which has good electrical conductivity and is relatively cheap. In addition, copper has the advantages of being easy to stamp and having sufficient hardness.

[0086] Furthermore, if Figure 1As shown, the number of the notches 111 is at least three, and the at least three notches 111 divide the partition 11 into at least three partition segments 11 a.

[0087] In this embodiment, the number of the notches 111 is at least three, and the at least three notches 111 divide the partition 11 into at least three partition sections 11a. The number of the busbars 20 is at least three, and the number of the busbars 20 corresponds to the number of the notches 111. One busbar 20 passes through one notch 111 so that a part of the busbar 20 is located in the first assembly groove 101a, and another part of the busbar 20 is located in the second assembly groove 101b. The number of the notches 111 is three, and the three notches 111 include a first notch 111, a second notch 111, and a third notch 111, and the three busbars 20 include a first busbar 20, a second busbar 20, and a third busbar 20. The first bus bar 20 passes through the first notch 111 so that part of it is located in the first assembly groove 101a, and the other part is located in the second assembly groove 101b. Similarly, the second bus bar 20 passes through the second notch 111 so that part of it is located in the first assembly groove 101a, and the other part is located in the second assembly groove 101b. The third bus bar 20 passes through the third notch 111 so that part of it is located in the first assembly groove 101a, and the other part is located in the second assembly groove 101b.

[0088] Furthermore, if Figure 3 and Figure 4 As shown, the busbar 1 further includes a limiting member 12 , which is disposed on a groove wall of the assembly groove 101 and / or each of the at least three partition segments 11 a to limit the axial movement of the busbar 20 along the motor 3 .

[0089] In this embodiment, a stopper 12 is provided on the groove wall of the assembly groove 101, and / or a stopper 12 is also provided on each partition 11a. When the busbar 20 is arranged in the assembly groove 101, the stopper 12 can limit the axial movement of the busbar 20. Further, the stopper 12 has a guide surface. When the busbar 20 is inserted into the assembly groove 101 in the axial direction, the busbar 20 can extend into the bottom of the assembly groove 101 along the guide surface. When the busbar 20 is assembled in place, the busbar 20 is sandwiched between the stopper 12 and the groove bottom of the assembly groove 101, ensuring the position stability of the busbar 20 in the axial direction.

[0090] Furthermore, if Figure 4 As shown, the limiting member 12 includes a first limiting member 121 connected to the groove wall of the first assembly groove 101a; and / or a second limiting member 122 connected to the groove wall of the second assembly groove 101b.

[0091] In this embodiment, the first limiting member 121 is connected to the groove wall of the first assembly groove 101a, and the second limiting member 122 is connected to the groove wall of the second assembly groove 101b. Through the joint action of the first limiting member 121 and the second limiting member 122, the same bus bar 20 can be effectively limited, thereby ensuring the position stability of the bus bar 20. Specifically, when the first bus bar 20 passes through the first notch 111 and is located in the first assembly groove 101a and the second assembly groove 101b respectively, the first limiting member 121 can limit the first part of the first bus bar 20, and the second limiting member 122 can limit the second part of the first bus bar 20, so that the first bus bar 20 as a whole can be constrained by the limiting member 12, thereby achieving the position stability of the first bus bar 20 in the axial direction.

[0092] Furthermore, if Figure 1 , Figure 5 and Figure 6 As shown, at least three notches 111 are evenly arranged on the partition 11 around the central axis of the frame 10 .

[0093] In this embodiment, at least three notches 111 are evenly arranged on the partition 11 around the central axis of the frame 10, so that at least three busbars 20 with the same structure can be assembled on the frame 10.

For example, the at least three partition segments 11a include a first partition segment 11a, a first assembly groove 101a corresponding to the first partition segment 11a is provided with the head end of the first busbar 20, and a second assembly groove 101b corresponding to the first partition segment 11a is provided with the tail end of the second busbar 20 adjacent to the first busbar 20.

[0094] Embodiment 2

[0095] Different from the above-mentioned embodiment, this embodiment further defines that Figure 2 , Figure 5 and Figure 6 As shown, the busbar 1 further includes a support portion 13 , which is connected to the outer side wall of the frame 10 and extends in a direction away from the central axis of the frame 10 . The support portion 13 is used to assemble the connection terminals 33 of the motor 3 .

[0096] In this embodiment, a support portion 13 is provided on the outer side wall of the frame 10, and the support portion 13 extends away from the central axis of the frame 10. The support portion 13 is used to assemble the terminal 33 of the motor 3. By providing the support portion 13, the installation and positioning of the terminal 33 can be facilitated. Further, the support portion 13 and the frame 10 can be prepared by injection molding, with high connection strength and simple preparation process. Further, the number of the support portions 13 and the number of the terminal 33 are multiple, corresponding to each other.

[0097] Furthermore, if Figure 1 As shown, the busbar 1 further includes a mounting opening 133 , which is disposed on the support portion 13 , and the connection terminal 33 is inserted into the mounting opening 133 .

[0098] In this embodiment, a mounting opening 133 is further provided on the support portion 13, and the mounting opening 133 is used to assemble the wiring terminal 33, so that the wiring terminal 33 is inserted into the mounting opening 133, thereby reducing the difficulty of assembling the wiring terminal 33 and improving the assembly accuracy of the wiring terminal 33, thereby preventing the wiring terminal 33 from being assembled with deviations and unable to be connected to other components of the motor 3 (such as the controller 32a, the mounting portion 23 of the bus 1).

[0099] Furthermore, if Figure 2 As shown, the support portion 13 includes a first support segment 131 and a second support segment 132 connected to each other. The first support segment 131 is located between the skeleton 10 and the second support segment 132. The mounting opening 133 is arranged on the first support segment 131. The axial thickness of the first support segment 131 is greater than the axial thickness of the second support segment 132.

[0100] In this embodiment, the support portion 13 includes a first support segment 131 and a second support segment 132 which are connected. The first support segment 131 is connected to the skeleton 10. The mounting opening 133 is provided on the first support segment 131. The axial thickness of the first support segment 131 is greater than the axial thickness of the second support segment 132, so that the first support segment 131 can provide reliable support for the terminal block 33. The axial thickness of the second support segment 132 which is not used for assembling the terminal block 33 is smaller, which can also reduce costs to a certain extent and avoid unnecessary waste of materials.

[0101] Furthermore, if Figures 1 to 6 As shown, the busbar 1 also includes an extension portion 14 , which is connected to the outer wall of the frame 10 away from the support portion 13 , and extends in a direction away from the central axis of the frame 10 . The extension portion 14 is used to connect to the stator frame 31 of the motor 3 .

[0102] In this embodiment, the busbar 1 further includes an extension portion 14, which is connected to the outer side wall of the frame 10 avoiding the support portion 13, and the extension portion 14 extends in a direction away from the central axis of the frame 10, thereby facilitating the matching connection between the extension portion 14 and the stator frame 31 of the motor 3. Specifically, there are multiple extension portions 14, and the multiple extension portions 14 are arranged at intervals on the frame 10. Specifically, the extension portion 14 and the frame 10 are an integrated structure, that is, they can be made by an injection molding process.

[0103] Embodiment 3

[0104] In this embodiment, the specific structure of the bus bar is described as follows: Figures 7 to 11 As shown, the busbar 20 includes a main body 21, which is embedded in the assembly groove 101; the main body 21 includes a first main section 211, a second main section 212 and a bending section 213, and the first main section 211 is located in the first assembly groove 101a; the distance between any point on the second main section 212 and the central axis of the motor 3 is smaller than the distance between any point on the first main section 211 and the central axis of the motor 3, and the second main section 212 is located in the second assembly groove 101b; the bending section 213 is connected between the first main section 211 and the second main section 212, and the bending section 213 is arranged in the notch 111.

[0105] In this embodiment, the main body 21 is divided into a first main body section 211, a second main body section 212 and a bending section 213, wherein the distance between any point on the first main body section 211 and the central axis of the motor 3 is greater than the distance between any point on the second main body section 212 and the central axis of the motor 3, that is, the distances between the first main body section 211 and the second main body section 212 and the central axis are not equal. At this time, the first main body section 211 and the second main body section 212 are connected by the bending section 213. Figure 7 and Figure 8 As shown, when there are multiple busbars 20 in the busbar 1, the first main body section 211 and the second main body section 212 of different radial sizes can facilitate the arrangement of multiple busbars 20 of the same structure on the skeleton 10, the first main body section 211 is located in the first assembly groove 101a, the bending section 213 is located in the notch 111, and the second main body section 212 is located in the second assembly groove 101b. Specifically, the first main body section 211 is a first arc section, the second main body section 212 is a second arc section, the first arc section and the second arc section have the same center, the radius of the first arc section is greater than the radius of the second arc section, that is, the first arc section and the second arc section are concentric but have different diameters. The first arc section and the second arc section are not complete rings, and the first arc section and the second arc section can be formed by bending or the like.

[0106] Furthermore, if Figures 8 to 10 As shown, on a plane perpendicular to the axis of the skeleton 10, the main body 21 of all the busbars 20 can form two incomplete circular rings. Specifically, the first main body segments 211 in the main body 21 of all the busbars 20 can form an incomplete first circular ring, and the second main body segments 212 in the main body 21 of all the busbars 20 can form an incomplete second circular ring, wherein the radius of the first circular ring is greater than the radius of the second circular ring.

[0107] Furthermore, if Figure 7 and Figure 8As shown, the number of bus bars 20 is at least three, and the structures of any two of the at least three bus bars 20 are the same; the at least three bus bars 20 include adjacent first bus bars 20 and second bus bars 20, and the first main section 211 of the first bus bar 20 is located on the side of the second main section 212 of the second bus bar 20 away from the central axis of the motor 3.

[0108] In this embodiment, if Fig. 9 As shown, at least three busbars 20 include adjacent first busbars 20 and second busbars 20, wherein the main body 21 includes a first side close to the central axis of the motor 3 and a second side away from the central axis of the motor 3. The connection method of two adjacent busbars 20 is as follows: the first main body section 211 of the first busbar 20 is located on the second side of the second main body section 212 of the second busbar 20, that is, any two adjacent busbars 20 of the at least three busbars 20 meet the above arrangement method. Therefore, when multiple busbars 20 with the same structure are arranged, interference between the busbars 20 will be avoided according to this arrangement method. In addition, according to this arrangement method, the density of the busbars 20 can be improved, and the size of the product can be further reduced.

[0109] Furthermore, the axial thickness of the main body portion 21 is greater than the radial thickness of the main body portion 21 .

[0110] In this embodiment, the axial thickness of the main body 21 is greater than the radial thickness of the main body 21. Due to the limitation of the arrangement of multiple bus bars 20, that is, the bus bars 20 are stacked in the radial direction of the skeleton 10, the bus bars 20 occupy more space in the radial direction. At this time, on the basis of meeting the current density requirements, in order to save the radial space of the skeleton 10, the axial thickness of the main body 21 is increased to ensure the bus bar 20's carrying capacity for current density.

[0111] Furthermore, the bus bar 20 further includes: Fig.10 and Fig.11 As shown, the connecting portion 22 is arranged at the end of the main body 21 and protrudes from the outer wall of the skeleton 10. The connecting portion 22 is used to connect the winding 31a of the motor 3; the connecting portion 22 includes a first connecting portion 221 and a second connecting portion 222, the first connecting portion 221 is arranged on the first main body segment 211; the second connecting portion 222 is arranged on the second main body segment 212.

[0112] In this embodiment, the busbar 20 also includes a connecting portion 22 arranged on the main body 21, through which the ends of each winding 31a of the multiple windings 31a of the stator of the motor 3 can be connected, and the good conductive performance of the busbar 20 can be used to achieve electrical connection of the corresponding winding 31a ends, without directly connecting the corresponding winding 31a terminals, thereby reducing the difficulty of wiring, facilitating efficient and fast operation of the production line, and helping to improve product production efficiency. Specifically, the main body 21 includes two ends, namely, a free end of a first main body segment 211 and a free end of a second main body segment 212, and the connecting portion 22 includes a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 is arranged on the first main body segment 211, and the second connecting portion 222 is arranged on the second main body segment 212, that is, the distance between the second connecting portion 222 and the central axis of the motor 3 is smaller than the distance between the first connecting portion 221 and the central axis, so that the radial extension length of the second connecting portion 222 is greater than the radial extension length of the first connecting portion 221, which can ensure that the wall surfaces of the first connecting portion 221 and the second connecting portion 222 that are away from the central axis are in the same arc surface, thereby facilitating the connection between the winding 31a and the connecting portion 22.

[0113] Furthermore, the connecting portion 22 includes a connecting section and an extending section, the connecting section is arranged on the main body 21 of the busbar 20 and extends along the axial direction of the motor 3; the extending section is directly or indirectly connected to the connecting section, the free end of the extending section is bent to form an assembly area, and the winding 31a of the motor 3 extends into the assembly area and is connected to the extending section.

[0114] In this embodiment, the connecting portion 22 includes an axially extending connecting section and an extension section connected to the connecting section. The free end of the extension section is bent to form an assembly area, which can facilitate the end of the winding 31a to quickly extend into the assembly area, and is also conducive to increasing the space for welding operation, reducing the difficulty of welding operation, so that the end of the winding 31a can be better welded to the connecting portion 22. Furthermore, the projection of the extension section on the axial end surface of the skeleton 10 is U-shaped.

[0115] Furthermore, the connecting portion 22 also includes a transition section, which is disposed between the connecting section and the extending section, and extends along the circumference of the skeleton 10 .

[0116] In this embodiment, the connecting portion 22 also includes a transition section, and the transition section is connected between the connecting portion and the extension section. The transition section extends along the circumference of the skeleton 10. By setting the transition section, it is possible to avoid the distance between two adjacent connecting portions 22 being too small to hinder the welding operation between the end of the winding 31a and the extension section. The distance between adjacent connecting portions 22 can be adjusted through the transition section, so that after multiple bus bars 20 are assembled, the multiple connecting portions 22 are evenly arranged on the skeleton 10.

[0117] Furthermore, there are multiple connecting parts 22 , and the extending directions of the transition sections in adjacent connecting parts 22 among the multiple connecting parts 22 are opposite.

[0118] In this embodiment, the number of the connecting parts 22 is multiple, specifically, one busbar 20 has four connecting parts 22, and two connecting parts 22 are located at the free end of the first main body section 211, and the other two connecting parts 22 are located at the free end of the second main body section 212. Among them, the extension directions of the transition sections in two adjacent connecting parts 22 of the multiple connecting parts 22 are opposite, that is, the directions of the transition sections in the circumferential extension of the two adjacent connecting parts 22 are opposite, one extends counterclockwise and the other extends clockwise, which can reduce the difficulty of stamping and forming on the one hand, and on the other hand, it can also make the multiple connecting parts 22 on a busbar 1 evenly arranged. Specifically, when a busbar 1 includes three busbars 20, and a busbar 20 includes four connecting parts 22, then a busbar 1 includes 12 connecting parts 22. By making the extension directions of the transition sections in the adjacent connecting parts 22 opposite, it can be ensured that the 12 connecting parts 22 are evenly arranged on the skeleton 10, which facilitates the connection between the end of the winding 31a and the connecting part 22, and reduces the difficulty of welding operation.

[0119] Furthermore, the bus 1 also includes a first matching groove 102a and a second matching groove 102b. The first matching groove 102a is opened on the skeleton 10 corresponding to the first connecting portion 221; the second matching groove 102b is opened on the skeleton 10 and the partition 11 corresponding to the second connecting portion 222 and passes through the skeleton 10 radially.

[0120] In this embodiment, when the busbar 20 is assembled on the frame 10, the first connection portion 221 is clamped in the first matching groove 102a, and the second connection portion 222 is clamped in the second matching groove 102b. The first connection portion 221 can be clamped on the groove wall of the first matching groove 102a, and the second connection portion 222 can be clamped on the groove wall of the second matching groove 102b, thereby limiting the circumferential movement of the busbar 20. Specifically, the number of the first connection portions 221 corresponds to the number of the first matching grooves 102a, and the number of the second connection portions 222 corresponds to the number of the second matching grooves 102b. Specifically, the number of the first connection portions 221 is two, and the number of the second connection portions 222 is two. It is worth noting that since the second connecting portion 222 is arranged on the second main body section 212 of the main body 21, and the second main body section 212 is located in the second assembly groove 101b, the second connecting portion 222 needs to contact the partition 11 and the skeleton 10. Therefore, the second matching groove 102b radially penetrates the partition 11 and the skeleton 10.

[0121] Furthermore, the busbar 20 further includes: a mounting portion 23 , which is arranged on the main body 21 away from the connecting portion 22 , and the mounting portion 23 is used to connect the connecting terminal 33 .

[0122] In this embodiment, the busbar 1 further includes a mounting portion 23, which is arranged on the main body 21 away from the connecting portion 22. The mounting portion 23 is used to connect the wiring terminal 33 of the motor 3. The mounting portion 23 is separately provided for the wiring terminal 33 for connection, so that the connection position of the wiring terminal 33 can be ensured to be accurate. Specifically, the number of the mounting portions 23 is 3. The 3 mounting portions 23 are arranged at intervals on the main body 21. According to the position of the wiring terminal 33 in the motor 3, a suitable mounting portion 23 is selected for connection. That is, not every mounting portion 23 among the multiple mounting portions 23 is used to connect the wiring terminal 33.

[0123] Furthermore, after extending in the axial direction, the mounting portion 23 bends and extends in a first direction away from the central axis of the motor 3 .

[0124] In this embodiment, the mounting portion 23 is extended in the axial direction and bent away from the central axis of the motor 3, so that the free end of the mounting portion 23 can extend toward the outside of the frame 10, thereby facilitating the connection of the wiring terminal 33 of the motor 3 with the mounting portion 23. In other words, the wiring terminal 33 does not need to extend into the frame 10 to connect with the mounting portion 23, which can reduce the difficulty of wiring, facilitate efficient and fast operation of the production line, and improve the production efficiency of the product.

[0125] Furthermore, the free end of the mounting portion 23 extends along the axial direction of the motor 3 to form a mounting surface, and the mounting surface can be connected to the wiring terminal 33 of the motor 3 .

[0126] In this embodiment, the mounting portion 23 first extends axially, then bends in a direction away from the central axis of the motor 3, and finally the free end of the mounting portion 23 can continue to extend axially along the motor 3 and form a mounting surface, which can be connected to the terminal 33, thereby increasing the contact area between the terminal 33 and the mounting portion 23, improving the connection strength and stability of the terminal 33, and reducing the probability of deformation of the terminal 33.

[0127] Furthermore, the mounting portion 23 includes a first mounting portion 231 and a second mounting portion 232 . The first mounting portion 231 is connected to the first main body section 211 of the main body 21 ; the second mounting portion 232 is connected to the second main body section 212 of the main body 21 .

[0128] In this embodiment, the mounting portion 23 includes a first mounting portion 231 and a second mounting portion 232. The first mounting portion 231 is connected to the first main body section 211, and the second mounting portion 232 is connected to the second main body section 212, that is, the distance between the first mounting portion 231 and the central axis is greater than the distance between the second mounting portion 232 and the central axis. In order to make the outer wall surfaces of the first mounting portion 231 and the second mounting portion 232 located in the same arc surface, the extension length of the first mounting portion 231 in the first direction can be made smaller than the extension length of the second mounting portion 232 in the first direction. At this time, the mounting surfaces of the first mounting portion 231 and the second mounting portion 232 for connecting with the wiring terminal 33 are both located in the same arc surface, thereby facilitating the assembly of the wiring terminal 33. Specifically, there are two first mounting portions 231 and one second mounting portion 232.

[0129] Furthermore, the bus 1 also includes a first mounting groove 103a and a second mounting groove 103b. The first mounting groove 103a is opened on the frame 10 corresponding to the first mounting portion 231; the second mounting groove 103b is corresponding to the second mounting portion 232 and is arranged on the frame 10 and the partition 11 along the radial direction of the frame 10.

[0130] In this embodiment, when the busbar 20 is assembled on the frame 10, the first mounting portion 231 is clamped in the first mounting groove 103a, and the second mounting portion 232 is clamped in the second mounting groove 103b. The first mounting portion 231 can be clamped on the groove wall of the first mounting groove 103a, and the second mounting portion 232 can be clamped on the groove wall of the second mounting groove 103b, thereby limiting the circumferential movement of the busbar 20. Specifically, the number of the first mounting portions 231 corresponds to the number of the first mounting grooves 103a, and the number of the second mounting portions 232 corresponds to the number of the second mounting grooves 103b. Specifically, the number of the first mounting portions 231 is two, and the number of the second mounting portions 232 is one. It is worth noting that since the second mounting portion 232 is arranged on the second main body section 212 of the main body 21, and the second main body section 212 is located in the second assembly groove 101b, the second mounting portion 232 needs to contact the partition 11 and the skeleton 10. Therefore, the second mounting groove 103b is radially penetrated through the partition 11 and the skeleton 10.

[0131] Furthermore, projections of the support portion 13 of the busbar 1 , the extension portion 14 of the busbar 1 , the connection portion 22 , and the mounting portion 23 on the axial end surface of the frame 10 do not overlap with each other.

[0132] In this embodiment, the projections of the support portion 13, the extension portion 14, the connection portion 22 and the mounting portion 23 of the busbar 1 on the axial end surface of the skeleton 10 do not overlap with each other, and when the extension portion 14 is connected to the stator frame 31, when the mounting portion 23 is connected to the terminal 33, and when the connection portion 22 is connected to the winding 31a, they will not interfere with each other, thereby reducing the difficulty of assembly.
