In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4 As shown, one embodiment of the present invention provides a copper busbar assembly, including a housing 1, a plurality of first copper busbars 2 and a plurality of second copper busbars 3; The housing 1 has a first mounting portion 11 and a second mounting portion 12 connected to each other, a plurality of first copper busbars 2 are arranged at intervals in the first mounting portion 11, and a plurality of second copper busbars 3 are arranged at intervals in the second mounting portion 12. The second mounting part 12 includes a first connecting section 121 and a second connecting section 122. The first connecting section 121 extends along a first direction, and the second connecting section 122 extends along a second direction. The first direction and the second direction intersect. The first connecting segment 121 connects the second connecting segment 122 and the first mounting portion 11, with the first mounting portion 11 and the second connecting segment 122 spaced apart. In this embodiment, "first direction" refers to the main extending direction of the first connecting segment 121. "Second direction" refers to the main extending direction of the second connecting segment 122. The phrase "the first direction intersects the second direction" indicates that the two parts are arranged at a certain angle in space (generally understood as perpendicular or approximately perpendicular). The first direction is an auxiliary direction. Figure 2 The X direction in the middle, the second direction is attached. Figure 2 The Y-axis of the structure. Existing discrete solutions require each power unit (such as two motors) to be equipped with an independent injection-molded copper busbar assembly and a corresponding plastic housing 1, with a large amount of plastic used for repeated molding of the housing 1. In contrast, this solution integrates multiple independent housings 1 into a connected structure through an integrated housing 1 design. At the same time, by using the "alternating arrangement of the first mounting part 11 and the second connecting section 122", a hollow area is formed between the first mounting part 11, the first connecting section 121, and the second connecting section 122, directly eliminating unnecessary solid plastic volume. This reduces the consumption of injection molding materials from the structural design source, significantly reduces the procurement cost of plastic raw materials, and avoids the material waste caused by the large amount of plastic used in traditional solutions. In addition, the integrated design significantly reduces the number of parts, simplifies the assembly process, and improves production efficiency, providing a highly integrated, low-cost, and highly reliable copper busbar solution for new energy vehicle motor controllers. It is understood that the innovation of this application lies only in the physical structure design, not in the improvement of circuit connection technology. This application does not make any innovation in the circuit connection method, current transmission path, or electrical performance of the copper busbar. The electrical connection function, current transmission characteristics, and electrical connection methods with the inverter module and drive motor of the copper busbar are all existing technologies, and this application does not involve any innovation in these circuit connections. The core innovation of this utility model lies in the reduction of the amount of injection molding material used through the integrated design of the housing 1 structure and the spaced arrangement of the copper busbar, thereby optimizing the injection molding process and product structure. This is an improvement in mechanical structure and injection molding process, and does not involve any innovation in circuit connection technology.

[0023] In one embodiment, along the second direction, the first mounting portion 11 has a first end and a second end opposite to each other, the second connecting section 122 has a third end and a fourth end opposite to each other, the first end of the first mounting portion 11 corresponds to the third end of the second connecting section 122, and the first connecting section 121 is connected between the first end of the first mounting portion 11 and the third end of the second connecting section 122; wherein the first direction is perpendicular to the second direction. In this embodiment, by clearly defining the perpendicular relationship between the first direction and the second direction and specifically limiting that the first connecting section 121 is precisely connected between the first end of the first mounting portion 11 and the third end of the second connecting section 122, an extremely compact and rigid L-shaped or "Ω"-shaped three-dimensional support structure is constructed. This optimized spatial layout not only enables the assembly to more efficiently adapt to two power units distributed in perpendicular orientations within the installation space, realizing precise spatial avoidance and docking, but also maximizes the hollow area between the first mounting portion 11 and the fourth end of the second connecting section 122 by arranging the main structural beam (the first connecting section 121) at the end. This measure further reduces the amount of plastic material and achieves better effects of lightweight design and cost control on the premise of ensuring the overall structural strength and stability, while improving the positioning accuracy and convenience during assembly.

[0024] In one embodiment, the plurality of first copper bars 2 include a first sub copper bar 21, a second sub copper bar 22 and a third sub copper bar 23, the body of the first sub copper bar 21, the body of the second sub copper bar 22 and the body of the third sub copper bar 23 are all located inside the first mounting portion 11, and the connecting end of the first sub copper bar 21, the connecting end of the second sub copper bar 22 and the connecting end of the third sub copper bar 23 are all located outside the first mounting portion 11; The plurality of second copper bars 3 include a fourth sub copper bar 31, a fifth sub copper bar 32 and a sixth sub copper bar 33, the body of the fourth sub copper bar 31, the body of the fifth sub copper bar 32 and the body of the sixth sub copper bar 33 are all located inside the second mounting portion 12, and the connecting end of the fourth sub copper bar 31, the connecting end of the fifth sub copper bar 32 and the connecting end of the sixth sub copper bar 33 are all located outside the second mounting portion 12. It can be understood that the connecting end of a sub copper bar includes an input end and an output end, and both the input end and the output end of the sub copper bar are located outside the housing 1. For example, the input ends of the sub copper bars are all located on the top side of the housing 1, and the output ends of the sub copper bars are located on the left side and / or the right side of the housing 1. By arranging three groups of first copper bars 2 (the first, second and third sub copper bars 23) and three groups of second copper bars 3 (the fourth, fifth and sixth sub copper bars 33), the three-phase transmission requirements of U, V and W for three-phase alternating current are perfectly matched. The integrated design integrates three-phase input and output connections into a single housing 1, which greatly simplifies the assembly process, improves space utilization, ensures efficient and reliable transmission of high-frequency, high-amplitude three-phase alternating current in the motor controller of new energy vehicles, and provides a compact, economical and highly stable connection solution for three-phase electric drive systems.

[0025] In one embodiment, the housing 1 has a first side and a second side opposite to each other along a third direction, and at least one of the first side and the second side of the housing 1 is provided with a material reduction structure 4; the first direction, the second direction and the third direction are perpendicular to each other. In this embodiment, the third direction is the thickness direction of the housing 1, and the first direction and the second direction are the length direction and the width direction of the housing 1, respectively. By providing the material reduction structure 4 on the first side and / or the second side of the housing 1, the wall thickness distribution of the housing 1 is optimized along the third direction (thickness direction), further reducing the amount of injection molding material used, reducing overall material consumption, and effectively avoiding injection molding defects such as shrinkage and bubbles caused by excessive local material thickness. With the hollow structure formed by the spaced arrangement of the first mounting part 11 and the second connecting section 122, the three-way material reduction is synergistically optimized, significantly reducing material costs and improving injection molding yield, providing reliable structural support for the high integration and low-cost manufacturing of new energy vehicle motor controllers.

[0026] In one embodiment, the adhesive reduction structure 4 includes a first adhesive reduction groove 41, which is arranged between the body of the first sub-copper busbar 21 and the body of the second sub-copper busbar 22. The adhesive reduction structure 4 also includes a second adhesive reduction groove 42, which is arranged between the body of the second sub-copper busbar 22 and the body of the third sub-copper busbar 23. By forming a precise adhesive reduction structure 4 between the first sub-copper busbar 21 and the second sub-copper busbar 22, and between the second sub-copper busbar 22 and the third sub-copper busbar 23, the amount of injection molding material used is further reduced, effectively avoiding plastic accumulation in the area between the copper busbars, significantly improving the injection molding quality, and eliminating defects such as shrinkage and bubbles caused by excessive local adhesive thickness. This provides a more optimized structural support for the high integration and low-cost application of three-phase AC drive systems in new energy vehicle motor controllers.

[0027] In one embodiment, there are multiple first adhesive reduction grooves 41, and a first reinforcing rib 5 is provided between two adjacent second adhesive reduction grooves 42; There are multiple second adhesive reduction grooves 42, and a second reinforcing rib 6 is provided between two adjacent second adhesive reduction grooves 42. By setting first reinforcing ribs 5 and second reinforcing ribs 6 between multiple first adhesive reduction grooves 41 and second adhesive reduction grooves 42, an optimized structural reinforcement network is formed, which effectively solves the problem of reduced strength in the adhesive reduction area. This distributed reinforcement design enables the housing 1 to maintain lightweight while significantly improving overall rigidity, avoiding structural deformation and stress concentration caused by excessive local adhesive reduction, and ensuring the stability of the three-phase copper busbar under high current and high frequency operation. At the same time, the reasonable layout of the reinforcing ribs, together with the adhesive reduction structure 4, further optimizes the injection molding process, reduces defects such as shrinkage and bubbles, improves product yield, and provides a highly reliable, low-cost, and highly integrated structural solution for new energy vehicle motor controllers.

[0028] In one embodiment, the adhesive reduction structure 4 includes multiple mutually spaced third adhesive reduction grooves 43, which are arranged in the second connecting section 122. A third reinforcing rib 7 is provided between adjacent third adhesive reduction grooves 43. By setting multiple mutually spaced third adhesive reduction grooves 43 in the second connecting section 122 and configuring the third reinforcing rib 7 between adjacent third adhesive reduction grooves 43, a perfect balance between adhesive reduction and reinforcement is achieved. This design effectively avoids a decrease in structural strength due to excessive local adhesive reduction, allowing the housing 1 to maintain lightweight while significantly improving local rigidity and deformation resistance. The reasonable layout of the third reinforcing rib 7, combined with the adhesive reduction grooves, ensures uniform wall thickness distribution, effectively preventing appearance defects such as shrinkage and bubbles during injection molding. Simultaneously, this synergistic design of multi-point adhesive reduction and multi-point reinforcement allows the housing 1 structure to further reduce material consumption and improve injection molding yield while ensuring the stability of three-phase AC power transmission, providing a highly reliable, highly integrated, and cost-effective structural solution for new energy vehicle motor controllers.

[0029] In one embodiment, the first reducing groove 41, the second reducing groove 42, and the third reducing groove 43 are all blind grooves. The sidewalls of the blind grooves maintain insulation properties, avoiding the risk of electrical short circuits between the three phases. At the same time, the blind groove structure effectively avoids defects such as shrinkage and bubbles caused by excessive local glue thickness during injection molding, significantly improving product yield. In addition, the insulation properties of the blind groove sidewalls and the conductivity properties of the bottom form a perfect match, providing a key guarantee for the high-reliability transmission of three-phase AC power in the motor controller of new energy vehicles, enabling the product to achieve a balance of high integration, high reliability, and low cost while maintaining lightweight design.

[0030] In one embodiment, the first adhesive reduction groove 41, the second adhesive reduction groove 42 and the third adhesive reduction groove 43 are all arranged on the first side of the housing 1; The adhesive reduction structure 4 also includes a fourth adhesive reduction groove 44, which is arranged on the second side of the housing 1. By concentrating the first adhesive reduction groove 41, the second adhesive reduction groove 42, and the third adhesive reduction groove 43 on the first side of the housing 1, and simultaneously setting the fourth adhesive reduction groove 44 on the second side, the symmetrical distribution and synergistic optimization of the adhesive reduction structures 4 on both sides of the housing 1 are achieved. While ensuring structural strength, the material utilization rate is significantly improved; the reasonable distribution of the adhesive reduction structures 4 on both sides effectively avoids the problem of uneven stress and deformation of the housing 1 caused by single-sided adhesive reduction, enabling the housing 1 to maintain excellent structural stability during three-phase power transmission.

[0031] According to the copper busbar assembly provided in this embodiment of the present invention, functional integration is achieved through an integrated housing 1 structure. The housing 1 is composed of a first mounting part 11 and a second mounting part 12 connected together. Multiple first copper busbars 2 and second copper busbars 3 are embedded in the corresponding mounting parts in a spaced-apart manner, forming an integrated conductive path for electrical connection and insulation encapsulation. The second mounting part 12 is composed of a first connecting segment 121 extending along a first direction and a second connecting segment 122 extending along a second direction. The two directions intersect to form an L-shaped or "U"-shaped spatial layout, allowing the assembly to adapt to the assembly requirements of multiple power units (such as dual motors). Meanwhile, the spacing between the first mounting section 11 and the second connecting section 122 creates a natural hollow structure in the housing 1, directly reducing the volume of solid plastic filling and significantly reducing the amount of injection molding material used. This achieves material savings and cost optimization from the design stage. Furthermore, the integrated design combines traditional multi-component solutions into a single structure, greatly reducing the number of parts and material consumption. This effectively avoids injection molding defects such as shrinkage and bubbles caused by uneven wall thickness, improves product appearance quality and structural stability, and enhances heat dissipation performance and production yield. This provides a highly integrated, low-cost, and highly reliable conductive connection solution for new energy vehicle motor controllers.

[0032] In addition, the present invention provides a connector including the copper busbar assembly described in the above embodiments.
