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 2This is a schematic diagram of another conductive connection component provided in an embodiment of this application. The conductive connection component may include: a housing 100 and a plurality of conductive bars 200.
[0020] The housing 100 in the conductive connection assembly may have a plurality of first grooves K1 and a plurality of second grooves K2. The first opening O1 of each first groove K1 and the second opening O2 of each second groove K2 of the first housing 100 are all located on the outer surface of the housing 100. The plurality of first grooves K1 and the plurality of second grooves K2 of the first housing 100 are arranged at intervals in the first direction X.
[0021] Multiple conductive bars 200 in the conductive connection assembly can be embedded and fixed inside the housing 100, and the multiple conductive bars 200 can be arranged at intervals in the first direction X. Here, the multiple conductive bars 200 of the conductive connection assembly 200 are arranged at intervals in the first direction X, which can ensure that no two adjacent conductive bars 200 will come into contact, thus ensuring the reliability of the electrical connection of the conductive connection assembly.
[0022] Each conductive bus 200 in the conductive connection assembly may have a first electrical contact 201 and a second electrical contact 202 at both ends. The multiple first electrical contacts 201 of the multiple conductive buses 200 may correspond one-to-one with the multiple first grooves K1 of the housing 100. The multiple second electrical contacts 202 of the multiple conductive buses 200 may correspond one-to-one with the multiple second grooves K2 of the housing 100.
[0023] Here, each first electrical contact 201 of each conductive bus 200 can be located in the corresponding first groove K1 of the housing 100 and can be exposed through the first slot O1 of the first groove K1. Each second electrical contact 202 of each conductive bus 200 can be located in the corresponding second groove K2 of the housing 100 and can be exposed through the second slot O2 of the second groove K2.
[0024] Since the first slot O1 of the first groove K1 of the housing 100 is located on the outer surface of the housing 100, the first electrical contact 201 exposed through the first slot O1 of the first groove K1 of the housing 100 in the conductive bus 200 can be used to connect with other structures for electrical conduction. For example, the first electrical contact 201 of the conductive bus 200 can be used for electrical connection with a motor in a subsequent embodiment.
[0025] Since the second slot O2 of the second groove K2 of the housing 100 is located on the outer surface of the housing 100, the second electrical contact 202 exposed through the second slot O2 of the second groove K2 of the housing 100 in the conductive bus 200 can be used to connect with other structures for conduction. For example, the second electrical contact 202 of the conductive bus 200 can be used to connect with a motor controller in a later embodiment.
[0026] It should be noted that the conductive connection assembly can be installed between the motor and the motor controller. Here, each first electrical contact 201 of the plurality of first conductive bars 200 of the conductive connection assembly can be connected to the motor, and each second electrical contact 202 of the plurality of first conductive bars 200 can be connected to the motor controller. 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 to achieve the rotation of the motor. Furthermore, the conductive connection assembly, the motor, and the motor controller can constitute an electric drive system in an automobile, where the rotation of the motor drives the wheels of the automobile.
[0027] In this application, multiple conductive busbars 200 in the conductive connection assembly are embedded and fixed inside the housing 100. The first electrical contact portion 201 of the conductive busbar 200 is located only within the corresponding first groove K1 of the housing 100, and the first electrical contact portion 201 can be exposed through the first slot O1 of the first groove K1 located on the outer surface of the housing 100 for connection with the motor. The second electrical contact portion 202 is located only within the corresponding second groove K2 of the housing 100, and the second electrical contact portion 202 can be exposed through the second slot O2 of the second groove K2 located on the outer surface of the housing 100 for electrical connection with the motor controller. In this way, while ensuring that the conductive connection assembly can be used to connect the motor and the motor controller, the multiple conductive busbars 200 in the conductive connection assembly do not occupy additional space, thereby making the structure of the conductive connection assembly compact and facilitating the miniaturization design of the electric drive system in which the conductive connection assembly is installed.
[0028] In summary, this application provides a conductive connection assembly, including a housing and a plurality of conductive bars. The plurality of conductive bars are all embedded and fixed inside the housing. The first electrical contact portion of each conductive bar is located only within a corresponding first groove in the housing, and the first electrical contact portion can be exposed through a first slot in the first groove located on the outer surface of the housing for connection to a motor. The second electrical contact portion is located only within a corresponding second groove in the housing, and the second electrical contact portion can be exposed through a second slot in the second groove located on the outer surface of the housing for electrical connection to a motor controller. This ensures that the conductive connection assembly can be used to connect a motor and a motor controller while also preventing the plurality of conductive bars from occupying additional space, thus making the conductive connection assembly compact and facilitating the miniaturization design of the electric drive system in which the conductive connection assembly is installed.
[0029] It should be noted that the structure used for connecting to the conductive connection component in the motor is a motor conductive busbar 010. The motor may include multiple motor conductive busesbars 010, and the multiple motor conductive busesbars 010 of the motor can correspond one-to-one with the multiple conductive buses 200 of the conductive connection component. Each motor conductive busbar 010 can be connected to the first electrical contact portion 201 of the corresponding conductive busbar 200.
[0030] Similarly, the structure in the motor controller used for connection with the conductive connection component is a controller conductive bus 020. The motor controller may include multiple controller conductive buses 020, and the multiple controller conductive buses 020 of the motor controller may correspond one-to-one with the multiple conductive buses 200 of the conductive connection component. Each controller conductive bus 020 may be connected to the second electrical contact portion 202 of the corresponding conductive bus 200.
[0031] Optional, please refer to Figure 3 , Figure 3 This is an exploded view of a conductive connection assembly provided in an embodiment of this application. The housing 100 in the conductive connection assembly may include: a main body portion 101, a first mounting portion 102, and a second mounting portion 103 connected to each other. The first mounting portion 102 and the second mounting portion 103 in the housing 100 may be located on opposite sides of the main body portion 101 in the second direction Y. That is, the first mounting portion 102, the main body portion 101, and the second mounting portion 103 in the housing 100 are arranged sequentially along the second direction Y.
[0032] like Figure 3 and Figure 4 As shown, Figure 4 This is a schematic diagram of another conductive connection assembly provided in this application embodiment. The first mounting portion 102 in the housing 100 may have multiple first grooves K1 on the side opposite to the main body portion 101 in the second direction Y. In the second direction Y, the depth of each first groove K1 in the first mounting portion 102 may be greater than the thickness of the corresponding first electrical contact portion 201 in the conductive busbar 200. In this way, after the multiple first electrical contacts 201 in the multiple conductive busbars 200 are respectively located in the corresponding first grooves K1 in the first mounting portion 102, the depth of the first groove K1 is greater than the thickness of the corresponding first electrical contact portion 201, so that no two adjacent first electrical contacts 201 will contact each other, thus ensuring the reliability of the electrical connection of the conductive connection assembly.
[0033] It should be noted that when the first electrical contact 201 in the conductive busbar 200 is used to connect with the corresponding motor conductive busbar 010 in the motor, the depth of the first groove K1 of the first mounting part 102 can be greater than the sum of the thickness of the first electrical contact 201 and the thickness of the motor conductive busbar 010. This ensures that after the first electrical contact 201 in the conductive busbar 200 is connected with the corresponding motor conductive busbar 010, no two adjacent motor conductive busbars 010 will come into contact with each other, thus ensuring the reliability of the motor's electrical connection.
[0034] It should also be noted that, such as Figure 4 As shown, the first mounting portion 102 may have multiple first ribs 1021 on the side facing away from the main body portion 101 in the second direction Y. The multiple first ribs 1021 of the first mounting portion 102 may be distributed at intervals along the first direction X, and any one of the first grooves K1 in the first mounting portion 102 may be located between two adjacent first ribs 1021. Here, the height of the first rib 1021 may be equal to the depth of the first groove K1. In this way, two first electrical contacts 201 located in any two adjacent first grooves K1 can be shielded by the first rib 1021 located between the two first grooves K1, ensuring that the two first electrical contacts 201 do not contact each other, thus ensuring the reliability of the electrical connection of the conductive connection assembly.
[0035] like Figure 3 and Figure 5 As shown, Figure 5 This is a schematic diagram of another conductive connection assembly provided in this application embodiment. The second mounting portion 103 in the housing 100 may have multiple second grooves K2 on one side in the third direction Z. Furthermore, in the third direction Z, the depth of each second groove K2 in the second mounting portion 103 may be greater than the thickness of the corresponding second electrical contact portion 202 in the conductive busbar 200. Thus, after the multiple second electrical contacts 202 in the multiple conductive busbars 200 are respectively located within the corresponding second grooves K2 in the second mounting portion 103, the depth of the second groove K2 is greater than the thickness of the corresponding second electrical contact portion 202, ensuring that no two adjacent second electrical contacts 202 will contact each other, thus guaranteeing the reliability of the electrical connection of the conductive connection assembly.
[0036] It should be noted that when the second electrical contact 202 in the conductive busbar 200 is used to connect with the corresponding controller conductive busbar 020 in the motor controller, the depth of the second groove K2 of the second mounting part 103 can be greater than the sum of the thickness of the second electrical contact 202 and the thickness of the controller conductive busbar 020. This ensures that after the second electrical contact 202 in the conductive busbar 200 is connected with the corresponding controller conductive busbar 020, no two adjacent controller conductive buses 020 will come into contact with each other, thus ensuring the reliability of the electrical connection of the motor controller.
[0037] It should also be noted that, such as Figure 5 As shown, the second mounting portion 103 may have multiple second ribs 1031 on the third direction Z side. The multiple second ribs 1031 of the second mounting portion 103 may be spaced apart along the first direction X, and any one of the second grooves K2 in the second mounting portion 103 may be located between two adjacent second ribs 1031. Here, the height of the second rib 1031 may be equal to the depth of the second groove K2. In this way, two second electrical contacts 202 located within any two adjacent second grooves K2 can be shielded by the second rib 1031 located between the two second grooves K2, ensuring that the two second electrical contacts 202 do not contact each other, thus ensuring the reliability of the electrical connection of the conductive connection assembly.
[0038] Optional, such as Figure 3 As shown, the conductive busbar 200 in the conductive connection assembly may include: a first conductive jumper 203 and a second conductive strip 204 connected to each other. The extension direction of the first conductive strip 203 in the conductive busbar 200 may be parallel to a third direction Z, and the end of the first conductive strip 203 away from the second conductive strip 204 may have a first electrical contact portion 201. The extension direction of the second conductive strip 204 in the conductive busbar 200 may be parallel to a second direction Y, and the end of the second conductive strip 204 away from the first conductive strip 203 may have a second electrical contact portion 202. This ensures that the multiple first grooves K1 for accommodating the multiple first electrical contacts 201 of the multiple first conductive busbars 200 can be located on the side of the first mounting portion 202 in the second direction Y away from the main body portion 201, and the multiple second grooves K2 for accommodating the multiple second electrical contacts 202 of the multiple first conductive busbars 200 can be located on the side of the second mounting portion 203 in the third direction Z.
[0039] Optional, such as Figure 3 and Figure 4 As shown, the extension length of the first conductive strip 203 in the conductive busbar 200 in the third direction Z can be less than the extension length of the second conductive strip 204 in the second direction Y.
[0040] Thus, as Figure 4 As shown, the first conductive strip 203 in the conductive busbar 200 can be located within the corresponding first groove K1 of the first mounting portion 102. That is, the first conductive strip 203 in the conductive busbar 200 can be embedded in the surface of the first mounting portion 102 and can be exposed through the first slot O1 of the corresponding first groove K1. The second conductive strip 204 in the conductive busbar 200 can be completely embedded inside the housing 100. In this way, the housing 100 can fully adapt to the structural form of the conductive busbar 200, further improving the compactness of the conductive connection assembly.
[0041] Optional, please refer to Figure 6, Figure 6 This is an exploded view of another conductive connection component provided in the embodiments of this application. The bottom of each of the first grooves K1 in the first mounting portion 102 in the housing 100 can have an injection port V.
[0042] The conductive connection assembly may further include multiple sealing portions 400. Each sealing portion 400 in the conductive connection assembly may correspond one-to-one with a multiple conductive busbar 200 and one-to-one with a multiple injection port V. Each sealing portion 400 in the conductive connection assembly can be filled into the interior of the main body 101 in the housing 100 through its corresponding injection port V, and each sealing portion 400 may be distributed around the position where it is connected to the first conductive strip 203 and the second conductive strip 204 in its corresponding conductive busbar 200.
[0043] In this way, the sealing portions 400, which fill the interior of the main body 101 of the housing 100 and are distributed around the corresponding conductive busbars 200, can block the first groove K1 on the first mounting portion 102 corresponding to the first electrical contact portion 201 of the conductive busbar 200, and the second groove K2 on the second mounting portion 103 corresponding to the second electrical contact portion 202 of the conductive busbar 200. That is, under the action of the sealing portions 400, the corresponding first groove K1 and second groove K2 in the housing 100 will not be connected.
[0044] Here, after the multiple first electrical contacts 201 of the multiple conductive bars 200 in the conductive connection assembly are respectively connected to the multiple motor conductive bars 010 in the motor, and the multiple second electrical contacts 202 of the multiple conductive bars 200 are respectively connected to the multiple controller conductive bars 020 in the motor controller, under the action of the sealing part 400 blocking the corresponding first groove K1 and second groove K2, the lubricating oil in the motor will not flow into the motor controller through the conductive bars 200. In this way, the thermal shock of the high temperature lubricating oil in the motor to the motor controller can be avoided, and the working reliability of the motor controller can be guaranteed.
[0045] It should be noted that the sealing portion 400 in the conductive connection assembly can be formed using silicone rubber 704-5 adhesive. During the manufacturing process of the sealing portion 400, silicone rubber 704-5 adhesive can be injected into the interior of the main body 101 through the corresponding injection port V. After the silicone rubber 704-5 adhesive solidifies, the sealing portion 400 is formed inside the main body 101 and distributed around the conductive busbar 200. Here, silicone rubber 704-5 adhesive is heat-resistant and has good insulation properties. Therefore, the sealing portion 400 can prevent the high-temperature lubricating oil in the motor from causing thermal shock to the motor controller.
[0046] It should also be noted that, since the injection port V is located at the bottom of the corresponding first groove K1, and since the length of the first conductive strip 203 in the conductive busbar 200 in the third direction Z is less than the length of the second conductive strip 204 in the conductive busbar 200 in the second direction Y, after the silicone rubber 704-5 adhesive is injected into the interior of the main body 101 through the injection port and solidifies, the sealing part 400 is distributed around the connection position of the first conductive strip 103 and the second conductive strip 204 in the conductive busbar 200.
[0047] Optional, such as Figure 4 and Figure 7 As shown, Figure 7 This is an exploded view of another conductive connection assembly provided in this application embodiment. The bottom of the first groove K1 of the first mounting portion 102 in the housing 100 may have a first embedding groove K11. At least a portion of the first electrical contact portion 201 in the conductive busbar 200 may be embedded and fixed into the first embedding groove K11. This ensures the reliability of the fixation of the first electrical contact portion 201 located in the corresponding first groove K1 on the outer surface of the housing 100.
[0048] like Figure 5 and Figure 8 As shown, Figure 8 This is a schematic diagram of a conductive connection assembly according to another embodiment of this application. The bottom of the second groove K2 of the second mounting portion 103 in the housing 100 may have a second embedding groove K21. At least a portion of the second electrical contact portion 202 in the conductive bus 200 may be embedded and fixed into the second embedding groove K21. This ensures the reliability of the fixation of the second electrical contact portion 202 located in the corresponding second groove K2 on the outer surface of the housing 100.
[0049] Optional, such as Figure 7 As shown, the bottom of the first embedding groove K11 of the first mounting portion 102 may have a first connecting hole S1. The conductive connection assembly may further include a first reinforcing connector 510 connected to the first electrical contact portion 201 in the conductive busbar 200. The first reinforcing connector 510 in the conductive connection assembly is embedded and fixed in the first connecting hole S1 of the first mounting portion 102. Here, the first electrical contact portion 201 of the conductive busbar 200 can be connected to the corresponding motor conductive busbar 010 in the motor through the first reinforcing connector 510.
[0050] like Figure 7 and Figure 8As shown, the bottom of the second embedding groove K21 of the second mounting portion 103 may have a second connecting hole S2. The conductive connection assembly may further include a second reinforcing connector 520 connected to the second electrical contact portion 202 in the conductive busbar 200. The second reinforcing connector 520 in the conductive connection assembly is embedded and fixed in the second connecting hole S2 of the second mounting portion 103. Here, the second electrical contact portion 202 of the conductive busbar 200 can be connected to the corresponding controller conductive busbar 020 in the motor controller through the second reinforcing connector 520.
[0051] Optional, such as Figure 7 As shown, the first electrical contact portion 201 in the conductive busbar 200 may have a first through hole V1. The first reinforcing connector 510 in the conductive connection assembly may have a first threaded hole V2. The first through hole V1 of the first electrical contact portion 201 and the first threaded hole V2 of the first reinforcing connector 510 are connected.
[0052] It should be noted that, as Figure 9 As shown, Figure 9 This is a schematic diagram of a motor and a conductive connection assembly provided in an embodiment of this application. The motor conductive busbar 010 in the motor may have a third through hole V5 at the end facing the conductive connection assembly. During the process of connecting the conductive connection assembly to the motor, the third through hole V5 can communicate with the first through hole V1 of the first electrical contact 201. The bolt can pass through the third through hole V5 of the motor conductive busbar 010 and the first through hole V1 of the first electrical contact 201 in sequence and then extend into the first threaded hole V2 of the first reinforcing connector 510. In this way, the motor conductive busbar 010, the first electrical contact 201 and the first reinforcing connector 510 can be connected together by the threaded connection of the bolt and the first threaded hole V2.
[0053] like Figure 7 and Figure 8 As shown, the second electrical contact portion 202 in the conductive bus 200 may have a second through hole V3. The second reinforcing connector 520 in the conductive connection assembly may have a second threaded hole V4. The first through hole V3 of the second electrical contact portion 202 may communicate with the second threaded hole V4 of the second reinforcing connector 520.
[0054] It should be noted that, as Figure 10 As shown, Figure 10This is a schematic diagram of a motor controller and a conductive connection assembly provided in an embodiment of this application. The end of the controller conductive busbar 020 facing the conductive connection assembly in the motor controller may have a fourth through hole. During the process of connecting the conductive connection assembly to the motor controller, the fourth through hole can communicate with the second through hole V3 of the second electrical contact 202. The bolt can pass through the fourth through hole of the controller conductive busbar 020 and the second through hole V3 of the second electrical contact 202 in sequence and then extend into the second bolt hole V4 of the second reinforcing connector 520. In this way, the controller conductive busbar 020, the second electrical contact 202 and the second reinforcing connector 520 can be connected together by the threaded connection of the bolt and the second bolt hole V4.
[0055] Optional, such as Figure 7 and Figure 11 As shown, Figure 11 This is a schematic diagram of the structure of a first reinforcing connector provided in an embodiment of this application. The end face of the first reinforcing connector 510 in the conductive connection assembly facing the first electrical contact portion 201 of the conductive bus 200 may have a first protruding ring 511. The first electrical contact portion 201 can be sleeved on the first protruding ring 511 through the first through hole V1, and the first electrical contact portion 201 can abut against the end face of the first reinforcing connector 510 where the first protruding ring 511 is provided. In this way, a reliable connection can be achieved between the first electrical contact portion 201 and the first reinforcing connector 510. Here, the first reinforcing connector 510 can be riveted to the corresponding first electrical contact portion 201 by a riveting process.
[0056] like Figure 7 and Figure 12 As shown, Figure 12 This is a schematic diagram of a second reinforcing connector provided in an embodiment of this application. The end face of the second reinforcing connector 520 in the conductive connection assembly facing the second electrical contact portion 202 of the conductive bus 200 may have a second protruding ring 521. The second electrical contact portion 202 can be sleeved on the second protruding ring 521 through the second through hole V3, and the second electrical contact portion 202 can abut against the end face of the second reinforcing connector 520 where the second protruding ring 521 is located. This allows for a reliable connection between the second electrical contact portion 202 and the second reinforcing connector 520. Here, the second reinforcing connector 520 can be riveted to the corresponding second electrical contact portion 202 using a riveting process.
[0057] Optional, such as Figure 13 and Figure 14 As shown, Figure 13 This is a schematic diagram of another conductive connection component provided in another embodiment of this application. Figure 14This is an exploded view of another conductive connection assembly provided in this application embodiment. The main body 101 of the housing 100 may have an annular groove H on the side facing the second mounting portion 103. The annular groove H of the second mounting portion 103 may be distributed around the second mounting portion 103. The conductive connection assembly may further include a sealing ring 600. A portion of the sealing ring 600 in the conductive connection assembly may be embedded in the annular groove H, and another portion may protrude from the surface of the main body 101 facing the second mounting portion 103.
[0058] It should be noted that the outer surface of the sealing ring in the conductive connection assembly has multiple protrusions, which can be located in the annular groove of the second mounting part 103 to ensure the connection reliability of the sealing ring 600 in the annular groove H.
[0059] In this application, as Figure 15 As shown, Figure 15 This is a schematic diagram of another motor controller and motor provided in an embodiment of this application. The motor controller has a housing 030. The controller conductive bus 020 in the motor controller is located inside the housing 030. The housing 030 has an opening O. After the conductive connection assembly is connected to the motor controller, the second mounting part 103 of the housing 100 in the conductive connection assembly can extend into the housing 030 through the opening O, so that the second electrical contact 202 located in the second groove K2 of the second mounting part 103 can be connected to the controller conductive bus 020.
[0060] Here, after the conductive connection assembly is connected to the motor controller, the side of the sealing ring 600 in the conductive connection assembly facing away from the main body 101 can abut against the outer casing 030, and the sealing ring 600 can be distributed around the opening O of the outer casing 030. In this way, the sealing ring 600 can seal the opening O of the outer casing 030 to prevent external contaminants from entering the outer casing 030 through the opening O, thus ensuring the operational reliability of the motor controller.
[0061] It should be noted that the sealing ring 600 in the conductive connection assembly can be made of acrylic rubber. Acrylic rubber has advantages such as good elasticity, excellent resistance to compression set, and good resistance to various greases and solvents. Therefore, the sealing ring 600 in the conductive connection assembly meets the sealing requirements of the housing 030 of the motor hole.
[0062] In this application, as Figure 13 and Figure 15 As shown, the conductive connection assembly further includes a plurality of fixing connectors 700. The main body 101 of the housing 100 may have a plurality of fifth through holes V7. The plurality of fixing connectors 700 may correspond one-to-one with the plurality of fifth through holes V7, and each fixing connector 700 may be embedded in the corresponding fifth through hole V7.
[0063] Here, each fixing connector 700 in the conductive connection assembly has a sixth through hole V8. The housing 030 has multiple seventh through holes V9, which can correspond one-to-one with the multiple fixing connectors 700. After the conductive connection assembly is connected to the motor controller, each seventh through hole V9 on the housing 030 communicates with the sixth through hole V8 of the corresponding fixing connector 700. By sequentially passing bolts through the sixth through hole V8 and the seventh through hole V9, the main body 101 of the housing 100 can be fixedly connected to the housing 030.
[0064] It should be noted that a portion of the fixing connector 700 in the conductive connection assembly may protrude from the side of the main body 101 facing the second mounting portion 102. In this way, after the main body 101 is connected to the outer casing 030, the fixing connector 700 protruding from the main body 101 abuts against the outer casing 030, thus preventing the casing 100 from deforming or cracking due to bolt pressure.
[0065] In this application, the multiple conductive busbars 200, multiple first reinforcing connectors 510, multiple second reinforcing connectors 520, and multiple fixing connectors 700 in the conductive connection assembly can be integrally injection molded with the housing 100. That is, the housing 100, multiple conductive busbars 200, multiple first reinforcing connectors 510, multiple second reinforcing connectors 520, and multiple fixing connectors 700 in the conductive connection assembly are a single integrated structure. This ensures the overall strength of the conductive connection assembly while simplifying the assembly process, improving production efficiency, and reducing component and maintenance costs.
[0066] In summary, this application provides a conductive connection assembly, including a housing and a plurality of conductive bars. The plurality of conductive bars are all embedded and fixed inside the housing. The first electrical contact portion of each conductive bar is located only within a corresponding first groove in the housing, and the first electrical contact portion can be exposed through a first slot in the first groove located on the outer surface of the housing for connection to a motor. The second electrical contact portion is located only within a corresponding second groove in the housing, and the second electrical contact portion can be exposed through a second slot in the second groove located on the outer surface of the housing for electrical connection to a motor controller. This ensures that the conductive connection assembly can be used to connect a motor and a motor controller while also preventing the plurality of conductive bars from occupying additional space, thus making the conductive connection assembly compact and facilitating the miniaturization design of the electric drive system in which the conductive connection assembly is installed.
[0067] 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.
[0068] 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.
