[0046] Embodiments of the Invention

[0047] ​For the purpose of facilitating the understanding of the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween. The terms "vertical", "horizontal", "left", "right", and similar expressions used in the present specification are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used in the present specification are intended to have the same meaning as commonly understood by one of ordinary skill in the art to which the present application pertains. The terminology used in the present specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the present specification, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0049] The electrically conductive connection seat of the motor stator is used to electrically connect each winding arranged in a ring shape of the stator, external current passes through the electrically conductive connection seat to be transmitted to each winding, and the current flowing through each winding causes each winding to generate a magnetic force to drive the rotor of the motor to rotate relative to the stator. The electrically conductive connection seat includes three main input terminals, and three phase different currents are transmitted to each winding by the three main input terminals respectively.

[0050] The applicant has also found that, in the existing motor stator, in order to meet the high performance and miniaturization requirements of users, the spacing between each winding is small, and in order to reduce the probability of short circuit between two adjacent windings, it is necessary to set an insulating paper between each winding, which has a high cost.

[0051] In view of this, referring to Figures 1-10 An embodiment of the present application provides an electrically conductive connection seat 100 for a motor 10, when the motor 10 is connected to each winding 200 by using the electrically conductive connection seat 100 in the embodiment, the volume of the winding can be optimized to improve the safety performance of the motor 10.

[0052] The conductive connecting seat 100 is used for electrical connection with the windings 200 of the motor stator. The number of windings 200 of the motor 10 can be determined according to specific requirements. For the convenience of description, the following embodiment is described by taking the motor 10 having twelve windings 200, and the twelve windings 200 being arranged around the first axis 400 as an example. Specifically, each winding 200 has two ends for connection with the conductive connecting seat 100, which are referred to as the first end 210 and the second end 220 of each winding 200 in the following, and the twelve windings 200 have twelve first ends 210 and twelve second ends 220 in total. The arrangement positions of the first end 210 and the second end 220 of each winding 200 can be determined according to specific requirements. In the embodiment, the first end 210 of each winding 200 is located at an outer ring relatively far away from the first axis 400, and the second end 220 of each winding 200 is located at an inner ring relatively close to the first axis 400.

[0053] In the embodiment, the conductive connecting seat 100 includes the first main input terminal 110, the first electrical connecting part 140, the second main input terminal 120, the second electrical connecting part 150, the third main input terminal 130, and the third electrical connecting part 160. The first main input terminal 110, the second main input terminal 120, and the third main input terminal 130 are used for corresponding acquisition of three-phase current. It can be understood that in other embodiments, the number of main input terminals and electrical connecting parts can be set according to the situation, for example, in a two-phase motor, only two main input terminals and two electrical connecting parts need to be provided. Herein, the features of the present application will be described in detail by taking a three-phase motor as an example.

[0054] The first main input terminal 110 is electrically connected with the first electrical connecting part 140, and the first electrical connecting part 140 is used for electrical connection with the first end 210 of the winding 200 of the motor 10. Specifically, in the embodiment, the first electrical connecting part 140 is used for electrical connection with the first ends 210 of four different windings 200, so that the first electrical connecting part 140 can transmit electrical energy to the four windings 200. Specifically, in the embodiment, the first electrical connecting part 140 is directly connected with the four windings 200.

[0055] In other embodiments, the first electrical connecting part 140 can also be directly connected with five, six or more windings 200, which will not be described herein.

[0056] Referring to Figure 1 and Figure 5 In the embodiment, the conductive connecting seat 100 is configured to make the windings 200 electrically connected therewith in parallel with each other. That is, the first end 210 of each winding 200 is electrically connected to the first electrical connecting part 140, and the second end 220 of each winding 200 is electrically connected to a point (specifically, to the fourth electrical connecting part 170 mentioned below).

[0057] In the embodiment, compared with the structure that the windings 200 directly connected with the first electrical connection part 140 are first connected in series with other windings 200 (the windings 200 not directly connected with the first electrical connection part 140) and then connected in parallel with each other, in order to ensure that the voltage obtained by each winding 200 is the same, the current flowing through the winding 200 in the application can be smaller (in the prior art, the windings 200 connected with the first electrical connection part 140 are in series, and the current is relatively larger), so the diameter of the wire wound into the winding 200 can be smaller, so that the volume of a single winding 200 is smaller, and the interval between the two adjacent windings 200 can be larger. In the above scheme, on the one hand, the probability of contact between the two adjacent windings 200 and short circuit is reduced, and the safety performance of the motor 10 is improved. On the other hand, the possibility of removing the insulating paper arranged between the two adjacent windings 200 is also increased, so that the material cost and processing cost of the motor 10 can be reduced.

[0058] The second main input terminal 120 is electrically connected with the second electrical connection part 150, and the second electrical connection part 150 is used to at least directly connect the first end 210 of the four windings 200. In the embodiment, the second electrical connection part 150 directly connects the first end 210 of the four windings 200. The second main input terminal 120 transmits the obtained current to the second electrical connection part 150, and the second electrical connection part 150 transmits the current to the four windings 200 connected therewith.

[0059] The third main input terminal 130 is electrically connected with the third electrical connection part 160, and the third electrical connection part 160 is used to at least directly connect the first end 210 of the four windings 200. In the embodiment, the third electrical connection part 160 directly connects the first end 210 of the four windings 200. The third main input terminal 130 transmits the obtained current to the third electrical connection part 160, and the third electrical connection part 160 transmits the current to the four windings 200 connected therewith.

[0060] In the embodiment, the conductive connecting seat 100 further comprises a fourth electrical connection part 170, and the fourth electrical connection part 170 is electrically connected with the second end 220 of all the windings 200. That is, the second end 220 of each winding 200 is electrically connected with the fourth electrical connection part 170, and the first end 210 of all the windings 200 is respectively electrically connected with one of the first main input terminal 110, the second main input terminal 120 or the third main input terminal 130. Thus, all the windings 200 of the motor stator are connected in star shape.

[0061] In the embodiment, the conductive connecting seat 100 can make each winding 200 connected with each main input terminal in separate parallel connection and star connection, so as to further reduce the current flowing between each winding 200, so that each winding 200 can adopt a smaller diameter wire, and the probability of contact short circuit between adjacent two windings 200 is reduced, thereby improving the safety performance of the motor 10.

[0062] In the embodiment, the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 extend along the first direction X (specifically, the axial direction of the motor 10), and are arranged in a circular array with the first axis 400 (specifically, the rotation axis of the motor 10) as the central axis, and the array angle is three hundred and sixty degrees. In other words, with the first axis 400 as the central axis, the separation angle between the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 along the first circumferential direction M is one hundred and twenty degrees. This structure arrangement can make the circumferential maximum size of the first electrical connecting part 140, the second electrical connecting part 150 and the third electrical connecting part 160 smaller, so that the first electrical connecting part 140, the second electrical connecting part 150 and the third electrical connecting part 160 can have less machining waste during processing, thereby reducing the processing cost of the first electrical connecting part 140, the second electrical connecting part 150 and the third electrical connecting part 160.

[0063] It can be understood that in other embodiments, the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 can also be designed according to actual needs, and other arrangement angles are not described here.

[0064] Specifically, in the embodiment, referring to Figures 3-6 , the first electrical connecting part 140 includes a first branch 141 and a second branch 142, and the first branch 141 and the second branch 142 are respectively electrically connected to one end of the first main input terminal 110. The first branch 141 is used to directly connect the first end 210 of two windings 200, and the second branch 142 is used to directly connect the first end 210 of another two windings 200. In this scheme, two separate parts, the first branch 141 and the second branch 142, are used to connect four windings 200 respectively, so that the overall volume of each part of the first electrical connecting part 140 can be smaller, and compared with the structure of using one part to connect four windings 200 at the same time, the first electrical connecting part 140 has lower processing difficulty, less machining waste and lower cost during processing. In other embodiments, the first branch 141 can also connect the first end 210 of three or more windings 200, and the second branch 142 can also connect the first end 210 of three or more windings 200.

[0065] In the embodiment, the first main input terminal 110 is arranged to extend along the first direction X (i.e. the motor axial direction), the first branch 141 is arranged to extend along a first circumferential direction M around the first axis 400, the second branch 142 is arranged to extend along a second circumferential direction N around the first axis 400, the first circumferential direction M is opposite to the second circumferential direction N, the first axis 400 is parallel to the first direction X and is away from the first main input terminal 110, and the first axis 400 can be specifically the rotation axis of the motor 10. Since the first branch 141 and the second branch 142 are arranged to extend along different circumferential directions respectively, the first branch 141 and the second branch 142 can be more convenient to connect the corresponding position windings 200, and the overall structure of the first electrical connection part 140 is more orderly and the assembly difficulty is lower.

[0066] Referring to Figures 5-7 In the embodiment, the first main input terminal 110 includes a first part 111, a second part 112 and a third part 113, the first part 111 is arranged to extend along the first direction X, the second part 112 is arranged to extend along the first circumferential direction M, and the third part 113 is arranged to extend along the second circumferential direction N. The first part 111, the second part 112 and the third part 113 can be integrally bent and formed.

[0067] One end of the second part 112 is connected to the first part 111, and the other end of the second part 112 is connected to one end of the first branch 141 close to the first part 111. The connection mode between the second part 112 and the first branch 141 can be welding. Since the first main input terminal 110 has the second part 112 extending along the first circumferential direction M, the circumferential length of the first branch 141 can be reduced, so that the volume of the first branch 141 can be smaller, the processing difficulty of the first branch 141 is reduced, and the processing waste during processing of the first branch 141 is reduced.

[0068] One end of the third part 113 is connected to the first part 111, and the other end of the third part 113 is connected to one end of the second branch 142 close to the first part 111. The connection mode between the third part 113 and the second branch 142 can be welding. Since the first main input terminal 110 has the third part 113 extending along the second circumferential direction N, the circumferential length of the second branch 142 can be reduced, so that the volume of the second branch 141 can be smaller, the processing difficulty of the second branch 142 is reduced, and the processing waste during processing of the second branch 142 is reduced.

[0069] The second electrical connection part 150 comprises a third branch 151 and a fourth branch 152, the third branch 151 is arranged along a first circumferential direction M around the first axis 400, and the fourth branch 152 is arranged along a second circumferential direction N around the first axis 400. The second main input terminal 120 comprises a fourth part 121, a fifth part 122 and a sixth part 123. The fourth part 121 extends along the first direction X, one end of the fifth part 122 is connected to one end of the fourth part 121 along the first direction X, and the other end of the fifth part 122 is connected to one end of the third branch 151 close to the fourth part 121. One end of the sixth part 123 is connected to one end of the fourth part 121 along the first direction X, and the other end of the sixth part 123 is connected to one end of the fourth branch 152 close to the fourth part 121. The fifth part 122 and the sixth part 123 are connected to the common end of the fourth part 121, and the fourth part 121, the fifth part 122 and the sixth part 123 are integrally bent and formed. In the above structural arrangement of the first main input terminal 110, the circumferential length of the third branch 151 and the fourth branch 152 can be reduced, so that the overall volume of the third branch 151 and the fourth branch 152 can be smaller, and the processing waste during processing of the third branch 151 and the fourth branch 152 is reduced.

[0070] The third electrical connection part 160 comprises a fifth branch 161 and a sixth branch 162, the fifth branch 161 is arranged along a first circumferential direction M around the first axis 400, and the sixth branch 162 is arranged along a second circumferential direction N around the first axis 400. The third main input terminal 130 comprises a seventh part 131, an eighth part 132 and a ninth part 133. The seventh part 131 extends along the first direction X, one end of the eighth part 132 is connected to one end of the seventh part 131 along the first direction X, and the other end of the eighth part 132 is connected to one end of the fifth branch 161 close to the seventh part 131. One end of the ninth part 133 is connected to one end of the seventh part 131 along the first direction X, and the other end of the ninth part 133 is connected to one end of the sixth branch 162 close to the seventh part 131. The eighth part 132 and the ninth part 133 are connected to the common end of the seventh part 131, and the seventh part 131, the eighth part 132 and the ninth part 133 are integrally bent and formed. In the above structural arrangement of the third main input terminal 130, the overall volume of the fifth branch 161 and the sixth branch 162 can be smaller, and the processing waste during processing of the fifth branch 161 and the sixth branch 162 is reduced.

[0071] In this embodiment, the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161 and the sixth branch 162 are respectively used to connect the first end 210 of two windings 200. The first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161 and the sixth branch 162 are collectively connected to the first end 210 of twelve windings 200 of the motor 10, and the fourth electrical connection part 170 is connected to the second end 220 of the twelve windings 200, so that the twelve windings 200 are connected in star shape.

[0072] In this embodiment, at least one branch of the first electrical connection part 140 and at least one branch of the second electrical connection part 150 are arranged in a stack along the first direction X, specifically, referring to Figure 2 、 Figure 5 、 Figure 9 and Figure 10 , the first branch 141 and the fourth branch 152 are at least partially arranged in a stack along the first direction X, which arrangement can reduce the overall space occupied by the first branch 141 and the fourth branch 152. Further, at least one branch of the first electrical connection part 140 and at least one branch of the third electrical connection part 160 are arranged in a stack along the first direction X, specifically, the first branch 141 and the sixth branch 162 are at least partially arranged in a stack along the first direction X, which arrangement can reduce the overall space occupied by the first branch 141 and the sixth branch 162.

[0073] In this embodiment, the first branch 141, the sixth branch 162 and the sixth part 123 are arranged in a stack along the first direction X in sequence. Thus, the overall space occupied by the first branch 141, the sixth branch 162 and the sixth part 123 is reduced.

[0074] Specifically, referring to Figure 2 、 Figure 5 、 Figure 9 and Figure 10In the embodiment, the first branch 141 comprises a first connecting terminal 1411 for electrically connecting with the first end 210 of the winding 200, the fourth branch 152 comprises a second connecting terminal 1521 for electrically connecting with the first end 210 of the winding 200, and the sixth branch 162 comprises a third connecting terminal 1621 for electrically connecting with the first end 210 of the winding 200. The second main input terminal 120 comprises a fourth portion 121, a fifth portion 122 and a sixth portion 123 extending along the first direction X, the fourth portion 121 is arranged extending along the first direction X, the fifth branch 161 is arranged extending along the first circumference M and connecting the third branch 151, and the sixth portion 123 is arranged extending along the second circumference N and connecting the fourth branch 152. Along the first circumference M, the first connecting terminal 1411, the second connecting terminal 1521 and the third connecting terminal 1621 are all located between the first portion 111 and the fourth portion 121. The above arrangement enables the connecting terminals electrically connecting with the adjacent windings 200 to be arranged adjacently, facilitating the electrical connection between the connecting terminals and the windings 200.

[0075] In the embodiment, the first connecting terminal 1411, the second connecting terminal 1521 and the third connecting terminal 1621 are adjacently distributed along the first circumference M in sequence. The arrangement of the first connecting terminal 1411, the second connecting terminal 1521 and the third connecting terminal 1621 in sequence along the first circumference M is the same as the arrangement of the three windings 200 connected by the first connecting terminal 1411, the second connecting terminal 1521 and the third connecting terminal 1621, further facilitating the connection between the connecting terminals and the windings 200. Preferably, in the embodiment, the first connecting terminal 1411, the second connecting terminal 1521 and the third connecting terminal 1621 are arranged in a circular array with the first axis 400 as the central axis, and the array angle is sixty degrees.

[0076] In the embodiment, the first branch 141, the third branch 151 and the fifth branch 161 are distributed along the first circumference M, and the positions of the first branch 141, the third branch 151 and the fifth branch 161 along the first direction X are flush. This scheme can reduce the overall space occupied by the first branch 141, the third branch 151 and the fifth branch 161 along the first direction X. The second branch 142, the fourth branch 152 and the sixth branch 162 are distributed along the first circumference M, and the positions of the second branch 142, the fourth branch 152 and the sixth branch 162 along the first direction X are flush. This scheme can reduce the overall space occupied by the second branch 142, the fourth branch 152 and the sixth branch 162 along the first direction X.

[0077] In the embodiment, the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161 and the sixth branch 162 are integrally formed by the sheet 184, and the thickness directions of the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161 and the sixth branch 162 are parallel to the first direction X. In this scheme, the thickness dimension of the remaining components of the conductive connecting seat 100 along the first direction X after the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 are removed can be further reduced, thereby reducing the overall space occupied by the conductive connecting seat 100.

[0078] Since the specific connection modes of the first branch 141, the third branch 151 and the fifth branch 161 can be the same, the structure sizes of the first branch 141, the third branch 151 and the fifth branch 161 can be the same in the embodiment. When producing the first branch 141, the third branch 151 and the fifth branch 161, a same component can be first produced, and then the component is the first branch 141 when the component is installed at the position of the first branch 141; the component is the third branch 151 when the component is installed at the position of the third branch 151; and the component is the fifth branch 161 when the component is installed at the arrangement position of the fifth branch 161.

[0079] Since the specific connection modes of the second branch 142, the fourth branch 152 and the sixth branch 162 can be the same, the structure sizes of the second branch 142, the fourth branch 152 and the sixth branch 162 can be the same in the embodiment. When producing the second branch 142, the fourth branch 152 and the sixth branch 162, a same component can be first produced, and then the component is the second branch 142 when the component is installed at the position of the second branch 142; the component is the fourth branch 152 when the component is installed at the position of the fourth branch 152; and the component is the sixth branch 162 when the component is installed at the arrangement position of the sixth branch 162.

[0080] Since the specific connection modes of the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 can be the same, the structure sizes of the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 are the same in the embodiment. When producing the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130, a same component can be first produced, and then the component is the first main input terminal 110 when the component is installed at the position of the first main input terminal 110; the component is the second main input terminal 120 when the component is installed at the position of the second main input terminal 120; and the component is the third main input terminal 130 when the component is installed at the arrangement position of the third main input terminal 130.

[0081] The specific arrangement position of the fourth electrical connection part 170 depends on specific requirements. In the embodiment, referring to Figures 4-5 , the fourth electrical connection part 170 is arranged on the inner side of the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 close to the first axis 400. This structural arrangement can further reduce the thickness dimension of the remaining components of the conductive connection seat 100 along the first direction X after removing the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130, compared with the structural arrangement in which the fourth electrical connection part 170 is stacked with at least one of the first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160 along the first direction X.

[0082] In the embodiment, the fourth electrical connection part 170 includes four connection pieces electrically connected to each other, which are arranged along the circumferential direction around the first axis 400. The four connection pieces are respectively a first connection piece 171, a second connection piece 172, a third connection piece 173 and a fourth connection piece 174. The first connection piece 171 includes a fourth connection terminal 1711, a fifth connection terminal 1712 and a sixth connection terminal 1713. The first connection terminal 1411 is arranged opposite to the fourth connection terminal 1711, and the first connection terminal 1411 and the fourth connection terminal 1711 are used to electrically connect the same winding 200. The second connection terminal 1521 is arranged opposite to the fifth connection terminal 1712, and the second connection terminal 1521 and the fifth connection terminal 1712 are used to electrically connect the same winding 200. The third connection terminal 1621 is arranged opposite to the sixth connection terminal 1713, and the third connection terminal 1621 and the sixth connection terminal 1713 are used to electrically connect the same winding 200. The first connection piece 171, the second connection piece 172, the third connection piece 173 and the fourth connection piece 174 collectively connect the second ends 220 of the twelve windings 200, so that the second ends 220 of all the windings 200 under the power supply of the three-phase circuit are electrically connected to each other.

[0083] In other embodiments, the fourth electrical connection part 170 can also include only two connection pieces or only one connection piece, which will not be described here. Compared with the connection mode of two connection pieces or one connection piece, arranging four connection pieces can make the process of the fourth electrical connection part 170 simple and save raw materials.

[0084] Referring to Figures 11-16The second embodiment of the present application also provides a conductive connecting seat 100, which comprises the components in the conductive connecting seat 100 in the first embodiment and a supporting component 190. For the convenience of description, the first main input terminal 110, the second main input terminal 120, the third main input terminal 130, the first electric connecting part 140, the second electric connecting part 150, the third electric connecting part 160 and the fourth electric connecting part 170 in the first embodiment are combined into a busbar assembly 101, which can only comprise the above components or can further comprise other electric connecting components.

[0085] In the embodiment, the conductive connecting seat 100 comprises the busbar assembly 101 and the supporting component 190. The supporting component 190 is used to connect and fix the components in the busbar assembly 101, which can be at least one of the first main input terminal 110, the second main input terminal 120, the third main input terminal 130, the first electric connecting part 140, the second electric connecting part 150, the third electric connecting part 160 or the fourth electric connecting part 170. It should be noted that, when the first electric connecting part 140 comprises the first branch 141 and the second branch 142, the first electric connecting part 140 itself is two components.

[0086] The supporting component 190 comprises a first supporting part 191 for supporting the first main input terminal 110. The first supporting part 191 can be made by an integral injection molding process and can support the first main input terminal 110 after the integral injection molding. In addition to supporting the first main input terminal 110, the first supporting part 191 also connects at least two independent components of the busbar assembly 101. In other words, the first supporting part 191 can be directly injection molded on the busbar assembly 101 after the assembly of the busbar assembly 101 is completed (which can be completely assembled or partially assembled), and the first supporting part 191 after the injection molding connects at least two components of the first main input terminal 110, the second main input terminal 120, the third main input terminal 130, the first electric connecting part 140, the second electric connecting part 150, the third electric connecting part 160 and the fourth electric connecting part 170.

[0087] In the conductive connecting seat 100 in the embodiment, on the one hand, the first supporting part 191 does not need to be arranged on the end cover 310 of the motor 10, which reduces the processing difficulty of the motor 10 housing 300 and facilitates the processing and assembly of the motor 10 housing 300. On the other hand, the first supporting part 191 can also connect at least two components in the busbar assembly 101, which makes the connection of the components in the busbar assembly 101 more stable.

[0088] The first support part 191 can be connected to any two parts of the busbar assembly 101 after injection molding. In the embodiment, the busbar assembly 101 includes the first electrical connection part 140, which is connected to the first main input terminal 110 and is also used to connect the first end 210 of the winding 200 of the motor 10. The first support part 191 is configured to be connected to the first electrical connection part 140 and at least one part other than the first main input terminal 110 during the integral injection molding. The first main input terminal 110 is in abutment (connection includes abutment and fixed connection) with the support part 190 and is supported and positioned by the first support part 191. In other words, in the embodiment, the first support part 191 is injection molded without being fixedly connected to the first main input terminal 110 and is connected to at least the first electrical connection part 140. The first main input terminal 110 is in abutment with the first support part 191 after the first support part 191 is injection molded. The first main input terminal 110 is supported and positioned by the first support part 191 on one hand, and is positioned by being connected to the first electrical connection part 140 on the other hand. This arrangement allows the first support part 191 to be injection molded without the first main input terminal 110 being installed, which is more convenient for injection molding of the first support part 191.

[0089] The support part 190 further includes a second support part 192 and a third support part 193, and the busbar assembly 101 further includes a second main input terminal 120 and a third main input terminal 130. The second support part 192 is used to support the second main input terminal 120, and the third support part 193 is used to support the third main input terminal 130. The manufacturing process of the second support part 192 and the third support part 193 can be the same as that of the first support part 191. The second support part 192 and the third support part 193 can be injection molded at the same time as the first support part 191. The second support part 192 is injection molded while being connected to at least two parts of the busbar assembly 101, and the third support part 193 is injection molded while being connected to at least two parts of the busbar assembly 101.

[0090] In the embodiment, the second support part 192 can be connected to the second electrical connection part 150 connected to the second main input terminal 120 and other parts other than the second main input terminal 120 when injection molded, and the second main input terminal 120 is in abutment with the second support part 192 after the second support part 192 is injection molded. The third support part 193 can be connected to the third electrical connection part 160 connected to the third main input terminal 130 and other parts other than the third main input terminal 130 when injection molded, and the third main input terminal 130 is in abutment with the third support part 193 after the third support part 193 is injection molded.

[0091] In this embodiment, the second electrical connection 150 connects the second main input terminal 120 and is also used to connect the first end 210 of the winding 200 of the motor 10. The third electrical connection 160 connects the third main input terminal 130 and is also used to connect the first end 210 of the winding 200 of the motor 10. The first electrical connection 140, the second electrical connection 150 and the third electrical connection 160 are arranged around the first axis 400. The first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 are respectively connected to the first end 210 of different windings 200.

[0092] The support component 190 further comprises an annular portion 194 which is integrally injection molded with the first support portion 191, the second support portion 192 and the third support portion 193, and which is integrally injection molded with the first electrical connection 140, the second electrical connection 150 and the third electrical connection 160. Further, the support component 190 is integrally formed, in particular integrally injection molded. The support component 190 can be integrally injection molded with the components of the busbar assembly 101. In this embodiment, the support component 190 is integrally injection molded with at least one part of the busbar assembly 101 (injection molding directly on this part). In particular, the support component 190 is integrally injection molded with all the parts of the busbar assembly 101 except the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130. When the support component 190 is integrally injection molded, the support component 190 is easier to process. After the support component 190 is processed, the support component 190 not only protects the busbar assembly 101, but also fixes the parts of the busbar assembly 101, and supports the first main input terminal 110, the second main input terminal 120 and the third main input terminal 130.

[0093] Referring to Figures 13-16The first support part 191 comprises a first support arm 1911 and a second support arm 1912 opposite to the first support arm 1911. The first support arm 1911 and the second support arm 1912 both extend along a direction parallel to the first axis 400 and away from the first annular end wall 1941 of the annular part 194. A surface of the first support arm 1911 facing the second support arm 1912 is provided with a first sliding groove 1913 extending along a direction parallel to the first axis 400, and the first sliding groove 1913 extends to an end of the first support arm 1911 away from the annular part 194. A wall surface of the first main input terminal 110 facing the first sliding groove 1913 is provided with a first protrusion 1111, and the first protrusion 1111 extends into the first sliding groove 1913. When the first main input terminal 110 is installed, the first protrusion 1111 can be slid into the first sliding groove 1913 from the end of the first support arm 1911 away from the annular part 194, and then the first main input terminal 110 is connected (specifically, welded) with the first electrical connection part 140, so as to realize positioning of the first main input terminal 110. The cooperation between the first sliding groove 1913 and the first protrusion 1111 can prevent the first main input terminal 110 from being displaced relative to the first support part 191 along a direction perpendicular to the first axis 400.

[0094] Further, the first main input terminal 110 comprises a first part 111 provided between the first support arm 1911 and the second support arm 1912, and the first part 111 is provided with the first protrusion 1111. A wall surface of the second support arm 1912 facing the first support arm 1911 is provided with a second sliding groove 1914 arranged along a direction parallel to the first axis 400, and the second sliding groove 1914 extends to an end of the second support arm 1912 away from the annular part 194. A wall surface of the first part 111 facing the second sliding groove 1914 is provided with a second protrusion 1112, and the second protrusion 1112 extends into the second sliding groove 1914. The cooperation between the second sliding groove 1914 and the second protrusion 1112 can further prevent the first main input terminal 110 from being displaced relative to the first support part 191 along a direction perpendicular to the first axis 400.

[0095] The first main input terminal 110 further comprises a second part 112 and a third part 113. The second part 112 is connected to the first part 111 at a side of the first part 111 close to the annular part 194, and extends along a first circumferential direction M around the first axis 400. The third part 113 is connected to the first part 111 at a side of the first part 111 close to the annular part 194, and extends along a second circumferential direction N around the first axis 400. The second circumferential direction N is opposite to the first circumferential direction M. The second part 112 comprises a U-shaped sheet 1121 arranged around an outer side of the first support arm 1911 away from the first axis 400. One end of the U-shaped sheet 1121 is connected to the first part 111, and the other end of the U-shaped sheet 1121 is arranged around the outer side and abuts against a wall of the first support arm 1911 away from the second support arm 1912. The structure of the U-shaped sheet 1121 can make the limiting between the first main input terminal 110 and the first support part 191 more reliable, and further prevent displacement between the first main input terminal 110 and the first support part 191 in a direction perpendicular to the first axis 400.

[0096] The first support part 191 further comprises a first baffle plate 1915 connected to an outer side of the second support arm 1912 away from the first axis 400. The first baffle plate 1915 abuts against a wall of the U-shaped sheet 1121 away from the first support arm 1911. The first baffle plate 1915 can prevent the U-shaped sheet 1121 from moving relative to the first support part 191 in a direction away from the first axis 400, thereby improving the limiting effect on the first main input terminal 110.

[0097] The busbar assembly 101 further comprises a fourth electrical connection part 170 for connecting the second ends 220 of all the windings 200 of the motor 10. The fourth electrical connection part 170 is connected to the annular part 194 during the process of integrally injection molding the annular part 194, so that the fixing effect of the support member 190 on the busbar assembly 101 is better. In other embodiments, the annular part 194 can also not be connected to the fourth electrical connection part 170, and the fourth electrical connection part 170 can be connected to the support member 190 by bonding, clamping or gluing, etc.

[0098] In this embodiment, the fourth electrical connection part 170 is arranged on an inner side of the annular part 194 close to the first axis 400. In other embodiments, the fourth electrical connection part 170 can also be arranged on an outer side of the annular part 194 away from the first axis 400, or the fourth electrical connection part 170 can be arranged in a stacked manner with the annular part 194 along the first direction X.

[0099] Referring to Figure 13 , Figure 15 and Figure 16In the embodiment, the annular portion 194 comprises an annular ring 195 and a plurality of third protrusions 199 connected to the inner side of the annular ring 195, each third protrusion 199 is arranged in a circular array with the first axis 400 as the central axis, each third protrusion 199 extends towards the first axis 400, and each third protrusion 199 is connected to the fourth electric connection portion 170. In the direction parallel to the first axis 400, the connection terminals of the fourth electric connection portion 170 for connecting the winding 200 are located between two adjacent third protrusions 199. In this scheme, on the one hand, the injection amount of the support component 190 can be saved, and on the other hand, the second end 220 of the winding 200 can be conveniently connected to the connection terminals of the fourth electric connection portion 170 by passing through two adjacent third protrusions 199.

[0100] The annular ring 195 comprises a first annular end wall 1941 and a second annular end wall 1942 opposite to each other. The first main input terminal 110 is arranged on one side of the first annular end wall 1941 of the annular ring 195, and each third protrusion 199 extends beyond the second annular end wall 1942 in the direction parallel to the first axis 400. Each third protrusion 199 can facilitate the abutment with the inner side of the insulating frame 230 of the winding 200 or the inner side of the winding 200 during the installation of the support component 190, thereby facilitating the positioning of the conductive connecting seat 100.

[0101] In the embodiment, the wall surface of each third protrusion 199 away from the first axis 400 is arc-shaped, and in the direction away from the annular ring 195, each arc surface is arranged to tilt towards the first axis 400. This scheme can facilitate the installation guidance of the conductive connecting seat 100 during the installation of the conductive connecting seat 100.

[0102] In the embodiment, referring to Figure 2 , Figure 11 and Figure 16, the annular ring 195 comprises an outer peripheral wall 196 arranged around the first axis 400. The first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160 each comprise a connection terminal (i.e. the first connection terminal 1411, the second connection terminal 1521 and the third connection terminal 1621) connected with the winding 200, and each connection terminal is extended out of the annular ring 195 by the outer peripheral wall 196. In this scheme, the outer diameter of the annular ring 195 can be reduced, thereby reducing the injection amount of the annular ring 195. Meanwhile, compared with the scheme in which each connection terminal is extended out of the annular ring 195 by the first annular end wall 1941 of the annular ring 195, the first annular end wall 1941 in this embodiment has fewer components arranged thereon and has a simpler structure, so that the first annular end wall 1941 has sufficient space to arrange the first support part 191, the second support part 192 and the third support part 193. In this embodiment, the connection terminal 143 of the first electrical connection part 140 connected with the first main input terminal 110 is also extended out of the annular ring 195 by the outer peripheral wall 196. The outer diameter of the annular ring 195 can be further reduced, thereby reducing the injection amount of the annular ring 195.

[0103] Referring to Figures 15-16 , the support part 190 further comprises a first clamping part 198 connected with the first support part 191, and the first clamping part 198 extends in a direction parallel to the first axis 400 and away from the first main input terminal 110. The first clamping part 198 is used to clamp the insulating frame 230 of the winding 200, so that when the first clamping part 198 of the conductive connecting seat 100 is clamped with the insulating frame 230 of the winding 200, the first end 210 of each winding 200 is arranged to face each connection terminal of the first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160 in the first direction X, and the second end 220 of each winding 200 is arranged to face each connection terminal of the fourth electrical connection part 170 in the second direction.

[0104] Referring to Figures 1-16 and Figure 21 , the application further provides a stator assembly 11 for a motor 10, which comprises the conductive connecting seat 100 of any one of the above, a stator core 600, an insulating frame 230 fixed on the stator core 600, and a plurality of windings 200 wound on the insulating frame 230. Each winding 200 is fixed on the insulating frame 230, and adjacent two windings 200 are arranged in a spaced relationship. That is, adjacent two windings 200 are arranged in a direct spaced relationship without an insulating paper arranged therebetween, thereby reducing the material cost of the motor 10.

[0105] Referring to Figures 17-21 , the application further provides a motor 10, which comprises Figures 1-16The stator assembly 11, rotor assembly 500, and housing 300 are shown in the embodiment. Each winding 200 is fixed to the insulating frame 230, and each winding 200 includes a first end 210 and a second end 220 that are electrically connected to the bus assembly 101.

[0106] The insulating frame 230 has a second snap-fit ​​portion 231. After the first snap-fit ​​portion 198 of the support member 190 snaps into the second snap-fit ​​portion 231 of the insulating frame 230, the first end 210 of each winding 200 is directly opposite to the respective connection terminals of the first electrical connection portion 140, the second electrical connection portion 150 and the third electrical connection portion 160 in the first direction X, and the second end 220 of each winding 200 is directly opposite to the respective connection terminals of the fourth electrical connection portion 170 in the second direction.

[0107] The insulating frame 230, conductive connector 100, and winding 200 of the motor 10 are all disposed within the housing 300. The housing 300 includes an end cover 310, which has an opening 311 through which the first main input terminal 110 and the first support portion 191 extend into the inner cavity of the housing 300. Specifically, the end cover 310 includes three openings 311. The first main input terminal 110 and the first support portion 191 extend into the inner cavity of the housing 300 through the first opening 311, the second main input terminal 120 and the second support portion 192 extend into the inner cavity of the housing 300 through the second opening 311, and the third main input terminal 130 and the third support portion 193 extend into the inner cavity of the housing 300 through the third opening 311.
