Abstract

The invention discloses a conductive connection assembly and an automobile, and belongs to the field of automobiles. The conductive connecting assembly comprises a first conductive connecting part and a second conductive connecting part. The first conductive connection part and the second conductive connection part are arranged separately. In the process of installing the conductive connection assembly between the motor controller and the motor, after the first conductive connection part and the second conductive connection part are respectively installed, the plurality of first conductive bars in the first conductive connection part are correspondingly connected with the plurality of second conductive bars in the second conductive connection part. And the fourth electric connection part of each second conducting bar can deform, so that the fourth electric connection part of the second conducting bar can compensate the installation error of the conducting connection assembly. In this way, the problem that assembling is difficult due to the fact that a space angle exists between the installation position of the controller conducting bar of the motor controller and the installation position of the motor conducting bar of the motor in the installation process of the conductive connecting assembly can be effectively solved.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0019] This application provides a conductive connection component; please refer to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a conductive connection component provided in an embodiment of this application. Figure 2 This is an exploded view of a conductive connection component provided in an embodiment of this application. The conductive connection component may include a first conductive connection portion 100 and a second conductive connection portion 200.

[0020] The first conductive connection portion 100 in the conductive connection assembly may include a first housing 101 and a plurality of first conductive bars 102. Each of the first conductive bars 102 in the first conductive connection portion 100 may have a first electrical contact portion 1021 and a second electrical contact portion 1022 at both ends. Each of the first conductive bars 102 in the first conductive connection portion 100 may be embedded and fixed inside the first housing 101, and the first electrical contact portion 1021 and the second electrical contact portion 1022 in the first conductive bars 102 may be distributed on the surface of the first housing 101.

[0021] That is, the first conductive busbar 102 in the first conductive connection portion 100 can be completely embedded into the first housing 101, with only the first electrical contact portion 1021 and the second electrical contact portion 1022 in the first conductive busbar 102 exposed on the surface of the first housing 101. This allows the first electrical contact portion 1021 and the second electrical contact portion 1022 to be connected to other structures for electrical conduction. For example, the first electrical contact portion 1021 in the first conductive busbar 102 can be connected to a motor controller, and the second electrical contact portion 1022 in the first conductive busbar 102 can be connected to the third electrical contact portion 2021 in the corresponding second conductive busbar 202 in a subsequent embodiment.

[0022] The second conductive connection portion 200 in the conductive connection assembly may include a second housing 201 and a plurality of second conductive bars 202. Each of the second conductive bars 202 in the second conductive connection portion 200 may have a third electrical contact portion 2021 and a fourth electrical contact portion 2022 distributed at both ends. A portion of each of the second conductive bars 202 in the second conductive connection portion 200 may be embedded and fixed inside the second housing 201, and both the third electrical contact portion 2021 and the fourth electrical contact portion 2022 of the second conductive bar 202 may extend outside the second housing 201.

[0023] Here, at least a portion of the second conductive bus 202 located between the third electrical contact 2021 and the fourth electrical contact 2022 can be embedded and fixed within the second housing 201. This allows the third electrical contact 2021 and the fourth electrical contact 2022 to extend outside the second housing 201, enabling them to connect with other structures for electrical conduction. For example, the third electrical contact 2021 in the second conductive bus 202 can be connected to the corresponding second electrical contact 1021 in the first conductive bus 102, and the fourth electrical contact 1022 in the second conductive bus 202 can be connected to a motor.

[0024] In this application, at least a portion of the first conductive bars 102 of the first conductive connection portion 100 can correspond one-to-one with the plurality of second conductive bars 202 of the second conductive connection portion 200, and the third electrical contact portion 2021 of each second conductive bar 202 in the second conductive connection portion 200 can be connected to the second electrical contact portion 1022 of the corresponding first conductive bar 102.

[0025] It should be noted that the first conductive connection portion 1021 of the first conductive busbar 102 can be connected to the motor controller, the second conductive connection portion 1022 of the first conductive busbar 102 can be connected to the third conductive connection portion 2021 of the corresponding second conductive busbar 202, and the fourth electrical connection portion 2022 of the second conductive busbar 202 can be connected to the motor. In this way, the conductive connection assembly enables an electrical connection between the motor controller and the motor, allowing the motor controller to supply current to the motor through the conductive connection assembly, thereby achieving motor rotation.

[0026] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a motor controller and a motor according to an embodiment of this application. The structure in the motor controller used for connection with the conductive connection component is a controller conductive busbar 010, and the structure in the motor used for connection with the conductive connection component is a motor conductive busbar 020. The distance between the installation position of the controller conductive busbar 010 and the installation position of the motor conductive busbar 020 is relatively large, and there is a spatial angle between them.

[0027] In related technologies, the conductive connection assembly used to connect the controller busbar 010 of the motor controller and the motor busbar 020 of the motor is an integral structure. Because the conductive connection assembly needs to accommodate the space between the installation positions of the controller busbar 010 and the motor busbar 020, its structure is complex, leading to difficulties in installation and significant installation errors.

[0028] In this application, the conductive connection assembly includes a first conductive connection portion 100 and a second conductive connection portion 200. The first conductive connection portion 100 and the second conductive connection portion 200 are separately disposed, and can be connected via a second electrical contact 1022 of the first conductive bus 102 in the first conductive connection portion 100 and a third electrical contact 2022 of the corresponding second conductive bus 202 in the second conductive connection portion 200. The first electrical contact 1021 of the first conductive bus 102 of the first conductive connection portion 100 is used to connect to the controller conductive bus 010 of the motor controller. The fourth electrical contact 2022 of the second conductive bus 202 of the second conductive connection portion 200 is used to connect to the motor conductive bus 020 of the motor.

[0029] Thus, during the process of installing the conductive connection assembly between the controller conductive busbar 010 of the motor controller and the motor conductive busbar 020 of the motor, the first conductive connection part 100 and the second conductive connection part 200 can be installed respectively, and then the plurality of first conductive busbars 102 in the first conductive connection part 100 and the plurality of second conductive busbars 202 in the second conductive connection part 200 can be connected accordingly.

[0030] Furthermore, in this application, the fourth electrical contact 2022 of each second conductive busbar 202 in the second conductive connection portion 200 is deformable. Thus, during the installation of the conductive connection assembly, the fourth electrical contact 2022 of the second conductive busbar 202 in the second conductive connection portion 200 can compensate for installation errors of the conductive connection assembly.

[0031] Thus, by separately installing the first conductive part 100 and the second conductive part 200 in the conductive connection assembly, and by compensating for the installation error of the conductive connection assembly by the fourth electrical connection part 2022 of the second conductive bus 202 in the second conductive connection part 200, the problem of assembly difficulties caused by the spatial angle between the installation position of the controller conductive bus 010 of the motor controller and the installation position of the motor conductive bus 020 of the motor during the installation of the conductive connection assembly can be effectively solved.

[0032] In summary, this application provides a conductive connection assembly, including a first conductive connection portion and a second conductive connection portion. The first and second conductive connection portions are separately disposed. During the installation of the conductive connection assembly between the controller conductive busbar of the motor controller and the motor conductive busbar of the motor, the first and second conductive connection portions can be installed separately, and then the plurality of first conductive busbars in the first conductive connection portion and the plurality of second conductive busbars in the second conductive connection portion can be connected accordingly. Furthermore, the fourth electrical contact portion of each second conductive busbar in the second conductive connection portion can be deformed, allowing the fourth electrical contact portion of the second conductive busbar to compensate for installation errors in the conductive connection assembly. Thus, by separately installing the first and second conductive portions in the conductive connection assembly, and by using the fourth electrical contact portion of the second conductive busbar to compensate for installation errors in the conductive connection assembly, the assembly difficulties caused by the spatial angle between the installation positions of the controller conductive busbar of the motor controller and the motor conductive busbar of the motor can be effectively solved during the installation of the conductive connection assembly.

[0033] Optional, please refer to Figure 4 , Figure 4This is a schematic diagram of the structure of a second conductive part provided in an embodiment of this application. The fourth electrical connection 2022 of the second conductive bus 202 in the second conductive part 200 may include a first bending member 20221 and an electrical connection body 20222 connected to each other. The first bending member 20221 in the fourth electrical connection 2022 can be closer to the second housing 201 relative to the electrical connection body 20222. And the end of the first bending member 20221 in the fourth electrical connection 2022 away from the electrical connection body 20222 can be connected to the portion of the second conductive bus 202 embedded and fixed in the second housing 201. Here, the first bending member 20221 in the fourth electrical connection 2022 can be bent, so that the first electrical connection 2022 can be deformed.

[0034] It should be noted that the plurality of first conductive busbars 102 in the first conductive connection portion 100 and the plurality of second conductive busbars 202 in the second conductive connection portion 200 can all be made of copper, that is, the plurality of first conductive busbars 102 in the first conductive connection portion 100 and the plurality of second conductive busbars 202 in the second conductive connection portion 200 can all be conductive busbars. Furthermore, the plurality of second conductive busbars 202 in the second conductive connection portion 200 can be flexible conductive busbar structures. This further ensures that the fourth electrical contact portion 2022 in the second conductive busbar 202 can deform.

[0035] Optionally, the fourth electrical contact portion 2022 of the second conductive bar 202 in the second conductive portion 200 may be distributed on one side of the second housing 201 in the first direction X, and the first bending member 20221 in the fourth electrical contact portion 202 may protrude from the surface of the electrical contact body 20222 that is away from the second housing 201 in the first direction X. The first bending member 20221 in the fourth electrical contact portion 202 is bent in a direction toward the second housing 201.

[0036] In this way, the first bending member 20221 can have sufficient strength to connect the portion of the second conductive busbar 202 embedded and fixed in the second housing 201 and the electrical contact body 20222. Furthermore, the first bending member 20221 bends in the direction toward the second housing 201, allowing the fourth electrical contact portion 202 to better accommodate installation errors in the conductive connection assembly, further reducing the installation difficulty of the conductive connection assembly.

[0037] Optional, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of another conductive connection component provided in an embodiment of this application. Figure 6This is a schematic diagram of a third conductive bus provided in an embodiment of this application. The conductive connection assembly may further include at least one third conductive bus 300. The third conductive bus 300 in the conductive connection assembly may have a fifth electrical contact portion 301 and a sixth electrical contact portion 302, respectively.

[0038] A portion of the plurality of first conductive bars 102 in the first conductive part 100 can correspond one-to-one with a plurality of second conductive bars 202 in the second conductive part 200. Another portion of the plurality of first conductive bars 102 in the first conductive part 100 can correspond one-to-one with at least one third conductive bar 300, and the fifth electrical contact 301 of each third conductive bar 300 can be connected to the second electrical contact 1022 of the corresponding first conductive bar 102. Here, the sixth electrical contact 302 in the third conductive bar 300 can be used to connect to the motor conductive bar 020 of the motor.

[0039] Optionally, the third conductive bus 300 is deformable. Here, unlike the first conductive bus 102 and the second conductive bus 202, none of the third conductive bus 300 is embedded or fixed inside the corresponding housing.

[0040] In this way, during the installation of the conductive connection assembly, the third conductive busbar 300 can compensate for the installation error of the conductive connection assembly, which can further solve the problem of assembly difficulties caused by the spatial angle between the installation position of the controller conductive busbar 010 of the motor controller and the installation position of the motor conductive busbar 020 of the motor during the installation of the conductive connection assembly.

[0041] Optional, such as Figure 6 As shown, the third conductive bus 300 may further include a second bending member 303 located between the fifth electrical connection portion 301 and the sixth electrical connection portion 302. Here, the second bending member 303 in the third conductive bus 300 can be bent, so that the third conductive bus 300 can be deformed.

[0042] It should be noted that, in the extending direction of the third conductive bus 300, the fifth electrical contact 301, the second bending member 303, and the sixth electrical contact 302 are arranged sequentially. Here, in the direction perpendicular to the extending direction of the third conductive bus and perpendicular to the plate surface of the third conductive bus 300, the second bending member 303 can be bent toward one side of the third conductive bus 300 or toward the other side of the third conductive bus 300. This embodiment does not specifically limit this.

[0043] It should also be noted that at least one third conductive bus 300 in the conductive connection assembly can also be made of copper, that is, the third conductive bus 300 can be a conductive bus. Here, the third conductive bus 300 can be a flexible conductive bus structure. This can further ensure that the third conductive bus 300 can be deformed.

[0044] Optional, such as Figure 2 and Figure 7 As shown, Figure 7 This is a schematic diagram of another conductive connection assembly provided in this application embodiment. The overall extension direction of the third conductive bus 300 can be parallel to the second direction Y. The sixth electrical contact portion 302 in the third conductive bus 300 and the plurality of fourth electrical contacts 2022 in the plurality of second conductive buses 202 can be distributed at intervals along the second direction Y. Here, it is possible to avoid mutual contact between the plurality of fourth electrical contacts 2022 in the second conductive buses 202 and the sixth electrical contact portion 302 of the third conductive bus 300, thus ensuring the reliability of the electrical connection of the conductive connection assembly.

[0045] Optional, such as Figure 2 and Figure 6 As shown, the plurality of first electrical contacts 1021 in the plurality of first conductive bars 102 of the first conductive part 100 can be spaced apart along a first direction X, and at least a portion of the second electrical contacts 1022 in the plurality of first conductive bars 102 of the first conductive part 100 can be spaced apart along a third direction Z. In this way, the plurality of first electrical contacts 1021 in the plurality of first conductive bars 102 will not contact each other, and the plurality of second electrical contacts 1022 in the plurality of first conductive bars 102 will not contact each other, ensuring the reliability of the electrical connection of the conductive connection assembly.

[0046] Here, the first direction X, the second direction Y, and the third direction Z can intersect each other pairwise. For example, the first direction X, the second direction Y, and the third direction Z can intersect each other perpendicularly.

[0047] Optional, such as Figure 8 As shown, Figure 8 This is an exploded view of another conductive connection component provided in the embodiments of this application. The number of first conductive bars 102 in the first conductive part 100 can be three, the number of second conductive bars 202 in the second conductive part 200 can be two, and the number of third conductive bars 300 can be one.

[0048] like Figure 8 and Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of a first conductive part provided in an embodiment of this application. The first housing 101 in the first conductive part 100 may include: a first main body 1011, a first mounting part 1012, and a second mounting part 1013 connected to each other. The first mounting part 1012 and the second mounting part 1013 in the first housing 101 may be located on opposite sides of the first main body 1011 in the third direction Z.

[0049] The first mounting portion 1012 in the first housing 101 may have three first grooves K1 on the side opposite to the first main body portion 1011. The three first grooves K1 of the first mounting portion 1012 may be distributed at intervals along the first direction X, and may correspond one-to-one with the three first electrical contacts 1021 in the three first conductive bars 102 in the first conductive portion 100. Each first electrical contact 1021 in the first conductive portion 100 may be located in the corresponding first groove K1 of the first mounting portion 1012.

[0050] It should be noted that, as Figure 9 As shown, the first mounting portion 1012 may have four first partitions 10121 on the side opposite to the first main body portion 1011. The four first partitions 10121 of the first mounting portion 1012 are spaced apart in the first direction X, and each first groove K1 of the first mounting portion 1012 is located between any two adjacent first partitions 10121 among the four first partitions 10121.

[0051] Here, the three first electrical contacts 1021 of the three first conductive bars 102 are respectively located in the corresponding first grooves K1 in the first mounting part 1012. Since each first groove K1 of the first mounting part 1012 is located between any two adjacent first partitions 10121 of the four first partitions 10121, any two adjacent first electrical contacts 1021 of the three first electrical contacts 1021 will be separated by the first partitions 10121, ensuring that the three first electrical contacts 1021 will not come into contact with each other, thereby ensuring the reliability of the electrical connection of the conductive connection assembly.

[0052] like Figure 8 and Figure 9 As shown, the second mounting portion 1013 in the first housing 101 may have a first mounting platform 10131 and a second mounting platform 10132. The first mounting platform 10131 and the second mounting platform 10132 in the second mounting portion 1013 may be connected in the third direction Z and may be staggered in the first direction X.

[0053] It should be noted that, as Figure 8 The first housing 101 may further include a connecting plate 1014, one side of which may be fixedly connected to the first main body 1011. The first mounting platform 10131 and the second mounting platform 10132 of the second mounting part 1013 in the first housing 101 may both be fixed on the connecting plate 1014.

[0054] like Figure 8 and Figure 9As shown, the first mounting platform 10131 in the second mounting part 1013 may have two first mounting positions K2 on one side in the first direction X. The two first mounting positions K2 of the first mounting platform 10131 may be arranged along the third direction Z. Two second electrical contacts 1022 of the three first conductive bars 102 of the first conductive part 100 may be fixed on the two first mounting positions K2 of the first mounting platform 10131, and the two second electrical contacts 1022 fixed on the two first mounting positions K2 of the first mounting platform 10131 may be connected to the two third electrical contacts 2021 of the two second conductive bars 202 of the second conductive part 200, respectively.

[0055] It should be noted that the first mounting platform 10131 may also have a second partition 10131a, which can be located between the two first mounting positions K2. In this way, the two second electrical contacts 1022 of the two first conductive bars 102 respectively fixed on the two first mounting positions K2 can be separated by the second partition 10131a. Furthermore, after the two second electrical contacts 1022 of the two first conductive bars 102 are respectively connected to the two third electrical contacts 2021 of the two second conductive bars 2022, the two third electrical contacts 2021 of the second conductive bars 2022 can also be separated by the second partition 10131a. This ensures that the two second electrical contacts 1022 of the two first conductive bars 102 will not contact each other, and the two third electrical contacts 2021 of the two second conductive bars 202 will not contact each other, thereby ensuring the reliability of the electrical connection of the conductive connection assembly.

[0056] like Figure 8 and Figure 9 As shown, the second mounting platform 10132 of the second mounting portion 1013 of the first housing 101 may have a second mounting position K3 on each side in the first direction X. A second electrical contact 1022 of one of the three first conductive bars 102 of the first conductive portion 100 may be fixed on the second mounting position K3 of the second mounting platform 10132, and a second electrical contact 1022 of the first conductive bar 102 fixed on the second mounting position K3 may be connected to the fifth electrical contact 301 of the third conductive bar 300.

[0057] It should be noted that the first mounting platform 10131 and the second mounting platform 10132 in the second mounting part 1013 are staggered in the first direction X, so that the second electrical contact 1022 of the first conductive bus 102 fixed on the first mounting position K2 of the first mounting platform 10131 will not contact the second electrical contact 1022 of the first conductive bus 102 fixed on the second mounting position K3 of the second mounting platform 10132, and the third electrical contact 2021 of the second conductive bus 202 connected to the second electrical contact 1022 fixed on the first mounting position K2 will not contact the fifth electrical contact 301 of the third conductive bus 300 connected to the second electrical contact 1022 fixed on the second mounting position K3, thus ensuring the reliability of the electrical connection of the conductive connection assembly.

[0058] Optional, such as Figure 8 and Figure 10 As shown, Figure 10 This is a schematic diagram of another structure of the second conductive part provided in an embodiment of this application. The second housing 201 in the second conductive part 200 may include a second main body 2011 and a third mounting part 2012 connected to each other. The second main body 2011 of the second housing 202 may extend along the second direction Y. The third mounting part 2012 of the second housing 102 may be located at one end of the second main body 2011 near the first mounting platform 10131 of the second mounting part 1013 of the first housing 101 in the second direction Y.

[0059] like Figure 10 As shown, the third mounting portion 2012 of the second housing 201 may have two first outlets O1. The two first outlets O1 of the third mounting portion 2012 may be arranged along a third direction Z. The two first outlets O1 of the third mounting portion 2012 may correspond one-to-one with the two third electrical contacts 2021 in the two second conductive blocks 202 of the second conductive portion 200. Each third electrical contact 2021 of the second conductive portion 200 may extend out of the third mounting portion 2012 through the corresponding first outlet O1. That is, the two third electrical contacts 2021 in the two second conductive blocks 202 of the second conductive portion 200 may extend out of the second housing 201 through the corresponding first outlets O1. In this way, the connection between the two third electrical contacts 2021 in the two second conductive blocks 202 of the second conductive portion 200 and the corresponding two second electrical contacts 1022 in the three second electrical contacts 1022 of the first conductive portion 100 can be realized.

[0060] Optionally, the second main body portion 2011 of the second housing 201 may have two second outlets O2 on one side in the first direction X. The two second outlets O2 of the second main body portion 2011 may be located at the end of the second main body portion 2011 away from the third mounting portion 2012. The two outlets O2 of the second main body portion 2011 are arranged along the second direction Y. The two second outlets O2 of the second main body portion 2011 may correspond one-to-one with the two fourth electrical contacts 2022 in the two second conductive blocks 202 of the second conductive portion 200. Each fourth electrical contact 2022 of the second conductive portion 200 can extend out of the second main body portion 2011 through its corresponding second outlet O2. That is, the two fourth electrical contacts 2022 in the two second conductive blocks 202 of the second conductive portion 200 can extend out of the second housing 201 through their corresponding second outlets O2. This allows for the connection between the two fourth electrical contacts 2022 in the two second conductive blocks 202 of the second conductive portion 200 and the motor conductive block 020 of the motor.

[0061] In this application, as Figure 3 As shown, the number of controller busbars 010 of the motor controller can be three, and the number of motor busbars 020 of the motor can also be three.

[0062] The three first electrical contacts 1021 of the three first conductive bars 102 of the first conductive part 100 in the conductive connection assembly can be respectively connected to the controller conductive bar 010 of the motor controller. The two second electrical contacts 1022 of the three second electrical contacts 1022 of the three first conductive bars 102 of the first conductive part 100 can be respectively connected to the two third electrical contacts 2021 of the two second conductive bars 202 of the second conductive part 200.

[0063] One of the three second electrical contacts 1022 of the three first conductive bars 102 of the first conductive part 100 can be connected to the fifth electrical contact 301 of the third conductive bar 300. The two fourth electrical contacts 2022 of the two second conductive bars 202 of the second conductive part 200 can be connected to two of the three motor conductive bars 020 of the motor, respectively. The sixth electrical contact 302 of the third conductive bar 300 can be connected to one of the three motor conductive bars 020 of the motor.

[0064] In this way, the motor controller can convert the DC power supplied by the DC battery into three-phase AC power and then transmit it to the motor through the conductive connection structure to drive the motor to rotate.

[0065] In this application, as Figure 3 and Figure 11 As shown, Figure 11This is a schematic diagram of the structure of an electric motor provided in an embodiment of this application. The motor may also have a motor housing 030. The controller busbar 010 of the motor controller may be located outside the motor housing 030, and the motor busbar 020 of the motor may be located inside the motor housing 030.

[0066] A portion of the conductive connection assembly can be located within the motor housing 030 of the motor. The motor housing 030 may have an opening O, through which the conductive connection assembly can be installed into the motor housing 030. Here, one end of the three first electrical contacts 1021 of the first conductive portion 100 in the conductive connection assembly can be exposed through the opening O of the motor housing 030 to achieve connection between the multiple first electrical contacts 1021 and the controller conductive busbar 010 of the motor controller. The second conductive portion 200 and the third conductive busbar 300 in the conductive connection assembly can be located within the motor housing 030 to achieve connection between the two fourth electrical contacts 2022 of the second conductive portion 200 and the motor conductive busbar 020 of the motor, and connection between the sixth electrical contact 302 of the third conductive busbar 300 and the motor conductive busbar 020 of the motor.

[0067] During the installation of the conductive connection assembly, the first conductive part 100, the second conductive part 200, and the third conductive busbar 300 of the conductive connection assembly can be installed separately. The specific installation process is as follows: like Figure 12 and Figure 13 As shown, Figure 12 This is a schematic diagram of the structure of a motor and a conductive connection assembly provided in an embodiment of this application. Figure 13 This is a schematic diagram of another motor and conductive connection assembly provided in an embodiment of this application. First, the first conductive part 100 can be installed. Specifically, as shown... Figure 12 and Figure 9 As shown, the first mounting portion 1012 in the first housing 101 of the first conductive portion 100 may have two first fixing members 10122. The distribution positions of the two first fixing members 10122 of the first mounting portion 1012 may not coincide in the first direction X, and may not coincide in the second direction Y, that is, the two first fixing members 10122 of the first mounting portion 1012 may be distributed diagonally along the first mounting portion 1012.

[0068] like Figure 11 and Figure 12As shown, the motor housing 030 may have two first auxiliary fixing members 031. The two first auxiliary fixing members 031 of the motor housing 030 may be distributed around the opening O, and the two first auxiliary fixing members 031 of the motor housing 030 may be correspondingly and fixedly connected to the two first fixing members 10122 of the first housing 101 of the first conductive part 100. This achieves a fixed connection between the first housing 101 of the first conductive part 100 and the motor housing 030.

[0069] It should be noted that the two first auxiliary fixing parts 031 of the motor housing 030 and the two first fixing parts 10122 of the first housing 101 of the first conductive part 100 can all have threaded holes, so that the first housing 101 of the first conductive part 100 can be fixedly connected to the motor housing 030 by corresponding bolts.

[0070] like Figure 13 As shown, after the first housing 101 of the first conductive part 100 is fixedly connected to the motor housing 030, the first main body part 1011 and the second mounting part 1013 in the first housing 101 of the first conductive part 100 can be located inside the motor housing 030.

[0071] In this application, as Figure 9 and 12 As shown, the conductive connection assembly may further include a sealing ring 400. The sealing ring 400 may be located on the side of the first mounting portion 1012 of the first housing 101 facing the first body 1011. After the first housing 101 of the first conductive portion 100 is fixedly connected to the motor housing 030, the sealing ring 400 may abut against the surface of the motor housing 030 and may be distributed around the opening O of the motor housing 030. This can prevent debris from the external environment from entering the interior of the motor housing 030 through the opening O.

[0072] Furthermore, the two first fixing members 10122 of the first mounting part 1012 are distributed diagonally along the first mounting part 1012, so that after the first housing 101 of the first conductive part 100 is fixedly connected to the motor housing 030, the force applied by the first mounting part 1012 of the first housing 101 to the motor housing 030 is more uniform, thereby making the pressure on the sealing ring 400 more uniform, thus providing the sealing effect of the sealing ring 400.

[0073] like Figure 13As shown, after the first housing 101 of the first conductive part 100 is fixedly connected to the motor housing 030, the fifth electrical contact 301 of the third conductive bus 300 can be connected to the second electrical contact 1022 of the first conductive bus 102 fixed on the second mounting position K2 of the first housing 101. Furthermore, the sixth electrical contact 302 of the third conductive bus 300 can be connected to one of the corresponding motor conductive buses 020 of the three motor conductive buses 020 of the motor. In this way, the third conductive bus 300 is connected to both the first conductive part 100 and the motor conductive bus 020.

[0074] like Figure 14 and Figure 15 As shown, Figure 14 This is a schematic diagram of another motor and conductive connection assembly provided in an embodiment of this application. Figure 15 This is a schematic diagram of another motor and conductive connection assembly provided in this application embodiment. After the third conductive bus 300 is connected to the first conductive part 100 and the motor conductive bus 020 respectively, the second conductive part 200 can be installed. Specifically, the two third electrical contacts 2021 of the two second conductive buses 200 of the second conductive part 200 can be connected to the two second electrical contacts 1022 of the two first conductive buses 102 fixed on the first mounting position K1 of the first housing 101, and the two fourth electrical contacts 2022 of the two second conductive buses 200 of the second conductive part 200 can be connected to the corresponding two motor conductive buses 020 of the three motor conductive buses 020 of the motor.

[0075] It should be noted that, as Figure 11 and Figure 14 As shown, the second main body 2011 of the second housing 201 of the second conductive part 200 may have two second fixing members 20111. The motor housing 030 may have a second auxiliary fixing member 032. The second auxiliary fixing member 032 of the motor housing 030 may be fixedly connected to the second fixing member 20111 of the second housing 201 of the second conductive part 200. In this way, the second housing 201 of the second conductive part 200 and the motor housing 030 can be fixedly connected.

[0076] like Figure 16 As shown, Figure 16 This is a schematic diagram of a motor controller, conductive connection assembly, and motor provided in an embodiment of this application. After the conductive connection assembly is installed on the motor housing 030, the three controller conductive bars 010 of the motor controller can be correspondingly connected to the three first electrical contacts 1021 of the three first conductive bars 102 of the first conductive part 100 of the conductive connection assembly. This allows for the assembly of the motor controller, conductive connection assembly, and motor.

[0077] It should be noted that, please refer to Figure 17 , Figure 17 This is an exploded view of another conductive connection assembly provided in this application embodiment. The conductive connection assembly also includes three bolts 500. The first housing 101 of the first conductive connection portion 100 also has three first threaded holes V1. The three first threaded holes V1 of the first housing 101 can be correspondingly provided with the three second electrical contacts 1022 of the three first conductive busbars 100. Here, the three second electrical contacts 1022 of the three first conductive busbars 100, as well as the two third electrical contacts 2021 of the two second conductive busbars 200 and the fifth electrical contact 301 of the third conductive busbar 300, all have through holes.

[0078] During the assembly of the conductive connection assembly, the two through holes of the two third electrical contacts 2021 can be concentrically distributed with the two through holes of the corresponding two second electrical contacts 1022, and can also be concentrically distributed with the corresponding two first threaded holes V1. Thus, the bolt 500 can sequentially pass through the through holes of the third electrical contacts 2021 and the through holes of the second electrical contacts 1022, and then be threaded into the corresponding first threaded hole V1, thereby achieving a fixed connection between the third electrical contacts 2021 and the corresponding second electrical contacts 1022.

[0079] Similarly, during the assembly of the conductive connection assembly, the through hole of the fifth electrical contact 302 can be concentrically distributed with the through holes of the corresponding second electrical contacts 1022 among the three second electrical contacts 1022, and can also be concentrically distributed with the corresponding first threaded holes V1 among the three first threaded holes V1. In this way, the bolt 500 can sequentially pass through the through holes of the fifth electrical contact 302 and the through holes of the second electrical contacts 1022 and then be threaded into the corresponding first threaded hole V1, thereby achieving a fixed connection between the fifth electrical contact 302 and the corresponding second electrical contact 1022.

[0080] It should be noted that, as Figure 16 As shown, the first housing 101 also has three second threaded holes V1. The three second threaded holes V1 can be correspondingly provided with three first electrical contacts 1021. Referring to the above embodiment, the three first electrical contacts 1021 can be connected to the three controller busbars of the motor controller by bolts, which will not be described in detail here.

[0081] Similarly, the three motor conductive busbars 020 of the motor may have three threaded holes. Please refer to the above embodiment. The two fourth electrical contacts 2022 and the one sixth electrical contact 302 can be connected to the three motor conductive busbars 020 by bolts, which will not be described in detail here.

[0082] In summary, this application provides a conductive connection assembly, including a first conductive connection portion and a second conductive connection portion. The first and second conductive connection portions are separately disposed. During the installation of the conductive connection assembly between the controller conductive busbar of the motor controller and the motor conductive busbar of the motor, the first and second conductive connection portions can be installed separately, and then the plurality of first conductive busbars in the first conductive connection portion and the plurality of second conductive busbars in the second conductive connection portion can be connected accordingly. Furthermore, the fourth electrical contact portion of each second conductive busbar in the second conductive connection portion can be deformed, allowing the fourth electrical contact portion of the second conductive busbar to compensate for installation errors in the conductive connection assembly. Thus, by separately installing the first and second conductive portions in the conductive connection assembly, and by using the fourth electrical contact portion of the second conductive busbar to compensate for installation errors in the conductive connection assembly, the assembly difficulties caused by the spatial angle between the installation positions of the controller conductive busbar of the motor controller and the motor conductive busbar of the motor can be effectively solved during the installation of the conductive connection assembly.

[0083] This application also provides an automobile, which may include: a motor controller, a motor, and a conductive connection assembly. The conductive connection assembly in the automobile can be the same as the one described in the above embodiments. The conductive connection assembly in the automobile can be electrically connected to both the motor controller and the motor.

[0084] It should be noted that the motor can be connected to the drive wheels of the car. The motor controller can convert the DC power supplied by the DC battery into three-phase AC power, and then transmit it to the motor through this conductive connection structure to drive the motor to rotate, thereby driving the drive wheels of the car to rotate.

[0086] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
