However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0043] In order to fully understand the implementation of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present invention is not limited to the specific details familiar to those skilled in the art.
[0044] It should be understood that the purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present invention, and the singular forms "a", "an" and "said" / "the" are also intended to include plural forms, unless the context clearly indicates otherwise.

[0045] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0046] The "parallel" / "vertical" and similar expressions used in the present invention include an absolute parallel / vertical relationship and a roughly parallel / vertical relationship (for example, a relationship that differs from absolute parallel / vertical by -5° to +5°), which can have the same effect.
[0047] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.
[0048] The utility model provides a conductive adapter component, a motor controller component, a power assembly and a vehicle. Figures 1 to 7 A conductive adapter assembly, a motor controller assembly, a powertrain, and a vehicle according to some embodiments of the present utility model are described.
[0049] See also Figures 1 to 7According to some embodiments of the present utility model, the conductive adapter assembly 100 provided may include a plurality of conductive members 110 and a support seat 130. The conductive member 110 includes a first conductor segment 111, a second conductor segment 112, and a third conductor segment 113 connected in sequence. The rigidity of the second conductor segment 112 is less than that of the first conductor segment 111. That is, the second conductor segment 112 is more easily deformed than the first conductor segment 111. And the rigidity of the second conductor segment 112 is less than that of the third conductor segment 113. That is, the second conductor segment 112 is more easily deformed than the third conductor segment 113. The first conductor segment 111 is suitable for connecting to an electrical terminal of a motor (not shown). The third conductor segment 113 is suitable for connecting to an electrical terminal of a motor controller (not shown). The support seat 130 may include an insulating body 131. The insulating body 131 has electrical insulation properties. The insulating body 131 may be made of an electrically insulating material such as plastic, for example. The insulating body 131 is coated on the outside of a portion of the third conductor segment 113 of each conductive member 110.
[0050] According to the conductive adapter assembly 100 of the embodiment of the utility model, when multiple conductive members 110 are injection molded into the insulating body 131, the third conductor segment 113 of the multiple conductive members 110 has a large rigidity, thereby reducing or avoiding the deformation of the third conductor segment 113 during the injection molding process, thereby improving the yield and consistency of the conductive adapter assembly 100. The rigidity of the first conductor segment 111 of the conductive member 110 is greater than the rigidity of the second conductor segment 112, and the rigidity of the second conductor segment 112 is less than the rigidity of the third conductor segment 113. In this way, on the one hand, the second conductor segment 112 can be deformed adaptively when the first conductor segment 111 moves relative to the second conductor segment 112 and the third conductor segment 113 moves relative to the second conductor segment 112, thereby better adapting to the errors existing in the assembly process; on the other hand, it is also convenient to assemble and connect the conductive member 110 with the motor and the motor controller, thereby improving the convenience and reliability of installation.
[0051] Furthermore, the conductive member 110 is an integrated member. According to the conductive adapter assembly 100 of the embodiment of the utility model, since the conductive member 110 is an integrated member, the first conductor 111, the second conductor 112 and the third conductor 113 of the conductive member 110 do not need to be assembled by welding, which can solve the problems of poor welding effect and excessive contact resistance of the welding surface in the butt welding process in the related art, thereby ensuring the stability of the conductive performance of the conductive member 110.
[0052] Copper is a commonly used conductive material due to its low resistance, high conductivity, excellent processing performance, abundant sources and low cost. In an embodiment provided by the utility model, the conductive member 110 is made of copper material, for example, the conductive member 110 is a copper busbar.
[0053] In some optional embodiments, the first conductor segment 111 is provided with a connection hole 111a suitable for connecting to an electrical terminal of a motor (not shown). The connection hole 111a can be fastened to the electrical terminal of the motor by a fastener such as a screw. By providing the connection hole 111a in the first conductor segment 111, it is convenient to fasten and connect with the electrical terminal of the motor by a fastener.
[0054] In some embodiments, the first conductor segment 111 having a greater rigidity than the second conductor segment 112 can be realized by stacking conductive metal sheets and hardening them through polymer diffusion welding. In this case, the first conductor segment 111 is directly connected to the electrical terminal of the motor.
[0055] Since the polymer diffusion welding process is complex and costly, the hardening of a long copper bar is not cost-effective. Therefore, in other embodiments, the first conductor 111 having a greater rigidity than the second conductor 112 can be realized by welding a section of a common hard conductive member on a shorter hardened section made by polymer diffusion welding. In this case, the first conductor 111 is indirectly connected to the electrical terminal of the motor.
[0056] In some optional embodiments, the third conductor segment 113 is provided with a connection portion 113c suitable for connecting to an electrical terminal of a motor controller. The connection portion 113c can be assembled and connected to the electrical terminal of the motor controller by welding or the like.
[0057] Likewise, in some embodiments, the third conductor 113 having a greater rigidity than the second conductor 112 can be realized by stacking conductive metal sheets and hardening them through polymer diffusion welding. In this case, the third conductor 113 is directly connected to the electrical terminal of the motor controller.
[0058] In other embodiments, the third conductor 113 having greater rigidity than the second conductor 112 can be realized by welding a common hard conductive part to a shorter hardened section made of polymer diffusion welding. In this case, the third conductor 113 is indirectly connected to the electrical terminal of the motor controller.
[0059] Optionally, a portion of the insulating body 131 corresponding to the connecting portion 113c is provided with a notch 131a so that the connecting portion 113c can be exposed outside the insulating seat. By covering the insulating body 131 of the support seat 130 outside the third conductor segment 113 and providing the notch 131a to expose the connecting portion 113c, it is convenient to position and weld the connecting portion 113c and the electrical terminal of the motor controller to be connected.
[0060] See also Figure 1 , Figure 2 ,as well as Figures 5 to 7For example, the third conductor segment 113 may include a first portion 113a and a second portion 113b. The extension direction of the first portion 113a and the extension direction of the second portion 113b intersect. The first portion 113a is connected to the second conductor segment 112. At least part of the second portion 113b is covered by the insulating body 131. The connecting portion 113c is located at the second portion 113b. Since the third conductor segment 113 is not completely covered in the insulating body 131, but the first portion 113a is exposed outside the insulating body 131, the third conductor segment 113 can be used to limit the second conductor segment 112, so that the second conductor segment 112 and the insulating body 131 are arranged spaced apart. At the same time, compared with the technical solution of completely covering the third conductor segment 113 in the insulating body 131, it is possible to prevent the connection between the second conductor segment 112 and the third conductor segment 113 from being subjected to excessive force concentration and causing damage such as breakage, which helps to extend the service life of the conductive member 110.
[0061] Continue reading Figure 1 , Figure 2 ,as well as Figures 5 to 7 For example, the conductive adapter assembly 100 may include at least three conductive members 110. Three of the at least three conductive members 110 are configured as three-phase copper bars. In this way, the electrical connection between the motor and the power supply can be achieved through the three-phase copper bar, and different assembly environments can be adapted and better conductive performance can be obtained.
[0062] The number of the conductive parts 110 of the conductive adapter assembly 100 can be three, six, or an integer multiple of 3. It can be understood that a single electric control requires three conductive parts, a double electric control requires six conductive parts, a triple electric control requires nine conductive parts, a quad electric control requires twelve conductive parts, and so on. That is, the number of conductive parts 110 of each conductive adapter assembly 100 is a multiple of 3. Taking the number of conductive parts 110 of the conductive adapter assembly 100 as six as an example, the conductive adapter assembly 100 is suitable for connecting two motors and a motor controller, where the motor controller can be two physically independent sub-motor controllers, or it can be an integrated total motor controller.
[0063] See also Figures 2 to 4 ,as well as Figure 6 For example, the insulating body 131 may include a restraining portion 131 b suitable for restraining a cable or a wire harness. The restraining portion 131 b can restrain and position the cable or the wire harness so that the cable or the wire harness maintains a corresponding direction and posture at the insulating body 131 .
[0064] Optionally, the restraining portion 131b can be configured as a wire clamping groove. By providing the wire clamping groove on the support base 130, it is convenient to restrain and fix the signal wire, and avoid flying wires or the need for additional cable ties.
[0065] See also Figure 1 , Figure 2 ,as well as Figure 7 For example, the insulating body 131 may include a guide portion 131c adapted to guide and match to another guide portion (not shown) of the motor controller. By providing the guide portion 131c, when the conductive adapter assembly 100 is assembled and connected with the motor controller, the guide portion 131c is used to guide and match with another guide portion located on the motor controller, so that accurate positioning can be achieved quickly, which is conducive to improving assembly efficiency.
[0066] Optionally, the guide portion 131c may be a tapered guide column. Accordingly, another guide portion of the motor controller may be a guide hole.
[0067] like Figure 7 As shown, in addition, the support seat 130 may also include a metal bushing 132 with a threaded inner circumference. The metal bushing 132 is suitable for being screwed to the motor controller through a fastener. The metal bushing 132 and the insulating body 131 are fixedly connected, for example, the two are made into an integral part by an insert injection molding process. By providing the metal bushing 132, the durability and firmness of the fastening connection between the support seat 130 and the motor controller can be improved. Compared with the use of fasteners to directly connect the plastic structure of the support seat 130 to the motor controller, the addition of the metal bushing 132 can effectively extend the service life of the support seat 130 and the strength of the connection structure between the motor controller and the support seat 130. By adding the metal bushing 132 and the metal bushing 132 being higher than the insulating body 131, on the one hand, it is possible to reduce or avoid the torque attenuation problem existing when the surface of the fasteners such as bolts is attached to the insulating body, thereby effectively preventing the fasteners such as bolts from loosening, thereby improving the reliability and stability of the connection structure between the fasteners such as bolts and the support seat 130; on the other hand, it can prevent damage / crushing of the injection molded parts.
[0068] For example, a portion of the metal bushing 132 is disposed inside the insulating body 131. Another portion of the metal bushing 132 protrudes outside the insulating body 131. This can increase the length of the effective connection between the metal bushing 132 and the fastener, thereby improving the stability of the connection structure between the metal bushing 132 and the fastener. The portion of the metal bushing 132 located outside the insulating seat has an axial dimension ranging from 0.4 mm to 0.7 mm. It can be understood that in actual applications, the portion of the metal bushing 132 located outside the insulating seat has an axial dimension ranging from 0.4 mm to 0.7 mm.
[0069] Optionally, the metal bushing 132 may be a steel threaded sleeve. The metal bushing 132 has an internal thread and may also have an external thread to increase the strength of the connection structure between the metal bushing 132 and the support seat 130.
[0070] Optionally, the number of the metal bushings 132 is, for example, four or another number.
[0071] In other embodiments, the inner hole of the metal bushing may not be a threaded hole, but a through hole. In this embodiment, a fastener such as a bolt passes through the metal bushing and is connected to another fastener, thereby achieving the purpose of fastening.
[0072] For example, the conductive member 110 may include a plurality of conductive metal sheets stacked and arranged in a thickness direction. The conductive metal sheets are in the shape of long strips or strips. The thickness of the conductive metal sheets is smaller than the width of the conductive metal sheets. The width of the conductive metal sheets is smaller than the length of the conductive metal sheets. The portions of the conductive metal sheets corresponding to the first conductor segment 111 are welded to each other so that the first conductor segment 111 is hardened. The portions of the conductive metal sheets corresponding to the second conductor segment 112 are separably arranged relative to each other in the thickness direction. The portions of the conductive metal sheets corresponding to the third conductor segment 113 are welded to each other so that the third conductor segment 113 is hardened. The welding here may be, for example, polymer diffusion welding.
[0073] Optionally, the portions of the conductive metal sheets corresponding to the second conductor segment 112 are not welded to each other. When the second conductor segment 112 is deformed, the conductive metal sheets may be separated from each other or may be attached to each other.
[0074] Optionally, the thickness of each conductive metal sheet may be in the range of 0.1 mm to 0.5 mm.
[0075] In other embodiments, depending on different electrical parameters such as the current and voltage to be passed and the number of conductive metal sheets, the thickness of the conductive metal sheet may not be limited to 0.1 mm to 0.5 mm.
[0076] See also Figures 3 to 6For example, the conductive member 110 may include a first via hole 113d. The insulating body 131 may include a second via hole 131d. In a plane perpendicular to the hole depth direction of the first via hole 113d, the orthographic projection of the first via hole 113d and the orthographic projection of the second via hole 131d are arranged concentrically. By using the first via hole 113d of the conductive member 110, each conductive member 110 can be positioned by another positioning structure, and then the insulating body 131 is made into one with each conductive member 110 by using an injection molding process. This can improve manufacturing efficiency. The second via hole 131d of the insulating body 131 can be understood as being defined and formed by the positioning structure during the injection molding process. Since the second via hole 131d corresponds to the first via hole 113d, the first via hole 113d and the second via hole 131d are connected, which is beneficial to increase the contact area between the conductive member 110 and the air, and is beneficial to the heat dissipation of the conductive member 110. The second via hole 131d saves material and is beneficial to the heat dissipation of the conductive member 110. The positioning structure mentioned here may be, for example, a positioning column provided in the injection mold.
[0077] See also Figures 1 to 6, the conductive adapter assembly 100 of this embodiment includes a support seat 130 and six conductive members 110. The conductive member 110 and the support seat 130 are manufactured as an integral part. After the six conductive members 110 are hardened at both ends, they are placed side by side, and the distance between adjacent conductive members 110 meets the technical requirements of creepage distance and electrical clearance. The second part 113b of the third segment conductor 113 of each conductive member 110 is coated on the support seat 130. Compared with directly coating the untreated conductive member 110 with the support seat 130, the conductive member 110 with the hardened end can better ensure that the position does not change during the injection molding process, and is not easy to deform during the injection molding process. The connecting portion 113c of the conductive member 110 is exposed to the notch 131a of the insulating body 131, which is convenient for connecting to the IGBT ports of the motor controller. The first segment conductor 111 of the conductive member 110 is connected to the three-phase electrical terminals of the motor through the connecting hole 111a. Two conical guide posts are provided on the support seat 130 to ensure the position accuracy of the conductive adapter assembly 100 during the later assembly process. The conductive part 110 can be, for example, a layer of 0.2 mm thick copper sheets stacked together, and the copper sheets corresponding to the first conductor 111 and the third conductor 113 are welded and formed, and hardened at the same time. There is a section in the middle of the formed conductive part 110 as the second conductor 112. The second conductor 112 can be in a scattered shape, so that the conductive part 110 can be bent. After hardening, the third conductor 113 of the conductive part 110 can be bent 90°, and the bent horizontal part is covered on the insulating body 131, and the connecting part 113c is exposed in the notch 131a. The first conductor 111 of the conductive part 110 is provided with a connecting hole 111a, which is convenient for the later connection with the three-phase electrical terminals of the motor. Compared with the solution in the related art of butt-welding a soft copper busbar and a hard copper busbar to obtain a soft and hard conductive member 110, hardening both ends of the conductive member 110 can not only achieve better technical effects, but also improve product stability, simplify processing technology, and reduce production costs.
[0078] The conductive adapter assembly 100 provided by the embodiment of the utility model has the following beneficial effects:
[0079] (1) The two ends of the conductive member 110 used as a copper busbar are hardened, while the middle part is kept soft, thereby avoiding the disadvantages of butt welding of soft and hard copper busbars in the related art, while ensuring that the conductive adapter assembly 100 has good assembly adaptability and improving the fit of the conductive overlap surface.
[0080] (2) The copper busbar with one end hardened is partially covered on the insulating body 131 to realize the one-piece molding of the conductive adapter assembly 100, thereby preventing the soft copper busbar from being deformed during the injection molding process and improving the product processing accuracy.
[0081] (3) The support seat 130 is provided with a restraining portion 131b such as a wire groove, which eliminates the need for cable ties during the subsequent wiring process, thereby saving materials and avoiding disorder in the wiring harness arrangement.
[0082] (4) The support base 130 is provided with a tapered guide column, which can improve the assembly accuracy of the conductive adapter assembly 100 during the later installation process.
[0083] (5) Four metal bushings 132 such as steel sleeves are embedded in the support seat 130. The end surface of the metal bushing 132 is higher than the support seat 130 of the adjacent part to facilitate the fixing of the bolts and prevent the support seat 130 from being damaged when the bolts are pre-tightened and the torque of the bolts from being attenuated during use.
[0084] In summary, the utility model utilizes the hardening treatment at both ends of the conductive member 110, and partially covers the hardened end on the support seat 130, so as to replace the technical solution of covering the soft copper bar with the hard copper bar after the butt welding on the support seat 130 in the related art. Compared with the related art, the technical solution not only avoids the characteristic that the soft copper bar is easy to deform when directly injection-molded, but also avoids the defects such as poor welding and loose fitting of the butt surfaces when the soft copper bar and the hard copper bar are butt-welded, which causes excessive contact resistance, simplifies the manufacturing process, and can effectively improve the stability and reliability of the use of the copper bar. Moreover, the conductive adapter assembly 100 of the utility model is also convenient for assembly and connection with the motor and the motor controller, so as to improve the convenience and reliability of installation. The conductive adapter assembly 100 has a high degree of integration, a compact structure, and a small space occupation. At the same time, the conductive member 110 and the support seat 130 have a structure that ensures positioning accuracy, which is convenient for intelligent assembly and reduces manufacturing production costs.

For example, the third conductor segment 113 can be indirectly connected to the electrical terminal of the motor controller by welding a section of hard copper busbar. The ordinary hard copper busbar here can be understood as an integrally formed copper busbar that is not easily deformed. It can be understood by those skilled in the art that the hard copper busbar or the rigid copper busbar is relative to the soft copper busbar or the flexible copper busbar.

The common hard copper bar here can be understood as an integrally formed copper bar that is not easily deformed. It can be understood by those skilled in the art that the hard copper bar or rigid copper bar is relative to the soft copper bar or flexible copper bar.
