Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0058] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0059] The following is for reference. Figures 1-5 This invention describes an integrated magnetic ring assembly according to an embodiment of the present invention.

[0060] like Figures 1 to 5As shown, the integrated magnetic ring assembly according to an embodiment of the present invention includes: a three-phase busbar assembly 1, a filter magnetic ring assembly 2, and a protective shell 3. The three-phase busbar assembly 1 is inserted into the filter magnetic ring assembly 2 to achieve filtering when the three-phase busbar assembly receives three-phase power. In this embodiment, the protective shell 3 covers at least a portion of the three-phase busbar assembly 1 and the filter magnetic ring assembly 2, thereby achieving integration of the three-phase busbar assembly 1 and the filter magnetic ring assembly 2 through the covering of the protective shell 3. When it comes to the installation of the controller 100, there is no need to set up a separate installation structure for the filter magnetic ring assembly 2, reducing the space layout requirements of the motor controller 100. At the same time, the magnetic ring assembly in the prior art is a split magnetic ring assembly. When the split magnetic ring assembly encounters vibration, it will cause internal stress or collision, which will lead to the magnetic ring breaking, thus affecting the filtering effect.

[0061] Furthermore, the protective shell 3 is an integral piece, which can effectively protect the three-phase busbar assembly 1 and the filter magnetic ring assembly 2, preventing external impacts or interference from damaging the three-phase busbar assembly 1 and the filter magnetic ring assembly 2, and effectively improving the overall safety performance of the integrated magnetic ring assembly.

[0062] In one embodiment of this utility model, such as Figures 1 to 5 As shown, the three-phase busbar assembly 1 includes a first conductive copper busbar 11, a second conductive copper busbar 12, and a third conductive copper busbar 13. The filter magnetic ring assembly 2 includes three through holes, in which the first conductive copper busbar 11, the second conductive copper busbar 12, and the third conductive copper busbar 13 are respectively inserted, thereby ensuring that the filter magnetic ring assembly 2 can achieve the necessary filtering effect for each conductive copper busbar.

[0063] Furthermore, the three through holes are arranged along the first direction A, thereby ensuring that the integrated magnetic ring assembly has space to be arranged only in the first direction A, reducing the space requirements in the two directions perpendicular to the first direction A, and ensuring the space requirements of the integrated magnetic ring assembly during the assembly process.

[0064] For example Figures 3 to 4 As shown, the filter magnetic ring assembly 2 includes a housing cover 21, a filter magnetic ring 22, and a magnetic ring housing 23. The housing cover 21 encloses the magnetic ring housing 23, forming an accommodating space. The filter magnetic ring 22 is disposed within this accommodating space, thereby achieving dual protection for the filter magnetic ring 22. Under vibration conditions, the housing cover 21 and the magnetic ring housing 23 can form a certain protective space, within which the filter magnetic ring 22 can be protected from external impacts that could shatter the internal filter magnetic ring 22.

[0065] Furthermore, the magnetic ring housing 23 is a rigid component, which enhances the protective function of the magnetic ring housing. The material of the rigid component can be rigid plastic, rigid rubber, rigid metal, etc.

[0066] Furthermore, as a preferred embodiment, the magnetic ring housing 23 is a hard metal part. Hard metal parts can better withstand impacts from the outside and provide better protection for the filter magnetic ring 22. In addition, in order to prevent the housing cover 21 and the magnetic ring housing 23 from forming a shielding space and thus affecting the filtering effect, the present invention preferably uses the housing cover 21 as an insulating part to prevent shielding of the filter magnetic ring 22.

[0067] Furthermore, as a preferred embodiment, the magnetic ring housing 23 is made of aluminum alloy, which achieves lightweighting while ensuring protective strength.

[0068] according to Figure 3 As shown, the magnetic ring housing 23 is provided with a magnetic ring mounting part 231, and the filter magnetic ring 22 is sleeved on the outside of the magnetic ring mounting part 231. At the same time, the inner sidewall of the filter magnetic ring 22 cooperates with the outer sidewall of the magnetic ring mounting part 231 to prevent the filter magnetic ring 22 from being stressed or vibrated inside the filter magnetic ring assembly under vibration conditions, thereby preventing the filter magnetic ring 22 from being damaged inside.

[0069] Furthermore, the housing cover 21 is also provided with a through hole 211 to retain space for the three-phase busbar assembly 1 to pass through when the filter magnetic ring assembly 2 is inserted into the three-phase busbar assembly 1.

[0070] Furthermore, one end of the magnetic ring mounting part 231 is connected to the bottom wall of the magnetic ring housing 1, and the other end abuts against the through hole 211, thereby realizing the formation of the aforementioned accommodating space and enabling the housing cover 21 to be assembled with the magnetic ring housing 23.

[0071] Furthermore, as mentioned above, the three through holes are the first through hole 2311, the second through hole 2312, and the third through hole 2313 provided on the filter magnetic ring assembly 2. The three through holes are provided on the magnetic ring mounting part 231 and are spaced apart along the first direction. The three through holes are respectively inserted through the three-phase busbar assembly 1. The spaced arrangement of the three through holes can ensure that there is a certain creepage distance between any two three-phase copper busbars, thereby effectively preventing the risk of short circuit.

[0072] As a preferred embodiment, the filter magnetic ring 22 uses a nanocrystalline magnetic ring, which has higher permeability, higher Curie temperature and higher saturation magnetic flux density than ferrite magnetic rings of the same volume.

[0073] Furthermore, the protective shell 3 covers the aforementioned filter magnetic ring assembly 2, thereby achieving dual protection for the filter magnetic ring 22: namely, the first layer of protection for the filter magnetic ring provided by the protective shell, and the second layer of protection for the filter magnetic ring 22 provided by the magnetic ring housing 23 and housing cover 21 of the aforementioned filter magnetic ring assembly 2. The dual protection can ensure the external and internal protection of the filter magnetic ring 22 under working conditions with relatively strong vibration.

[0074] According to the appendix Figure 1and appendix Figure 2 As shown, the three-phase busbar assembly 1 according to an embodiment of the present invention includes a first conductive end 101 and a second conductive end 102. The first conductive end 101 and the second conductive end 102 are respectively disposed on opposite sides of the integrated magnetic ring assembly. The first conductive end 101 can carry the electrical connection on the first side, and the second conductive end 102 can carry the electrical connection on the second side opposite to the first side, thereby ensuring the space-saving effect and ensuring that the difficulty of spatial arrangement is not affected by the arrangement on both sides.

[0075] Furthermore, in this embodiment, the three-phase busbar assembly 1 includes a straight section and a bent section, which are connected together; the protective shell 1 covers the straight section to protect it while exposing part of the straight section to form a first conductive end 101; because the second conductive end 102 is to be located on the opposite side from the first conductive end 101, the second conductive end 102 is bent in a direction away from the first conductive end 101 to form the aforementioned bent section.

[0076] Specifically, the bending position of the aforementioned bending section is not strictly limited in this embodiment, and the bending position is selected according to the space layout requirements. In order to further reduce the impact of the bending part on the space, it is necessary to ensure that the bent copper busbar can fit against the surface of the protective shell 3 as much as possible, reduce the gap between the copper busbar and the protective shell 3, and reduce the space occupied by the copper busbar protruding outward.

[0077] Furthermore, the extension direction of the first conductive end 101 is perpendicular to the extension direction of the second conductive end 102. During the assembly process, the first conductive end 101 can be assembled first, and the extension direction of the second conductive end 102 being perpendicular to it can reduce the installation difficulty during the assembly process.

[0078] Furthermore, a receiving seat is formed on the protective shell 3, which cooperates with the second conductive end 102 to ensure that the force borne by the second conductive end 102 can be borne during the assembly process, so that the copper busbar at the second conductive end 102 will not be deformed due to the force, thereby affecting the service life and durability.

[0079] Furthermore, the three-phase busbar assembly 1 includes multiple conductive copper busbars, and the protective shell 3 forms a baffle wall, which is disposed between any two of the conductive copper busbars. Since the protective shell is made of non-insulating plastic, the baffle wall can ensure that no electromagnetic interference occurs between any two copper busbars, thereby ensuring good EMC performance.

[0080] Furthermore, the protective shell 3 is provided with mounting holes 32 for mounting the integrated magnetic ring assembly, eliminating the need for a separate assembly structure for the integrated magnetic ring assembly, thereby saving assembly space.

[0081] Furthermore, such as Figure 6 The integrated magnetic ring assembly further includes a connecting post 4. According to an embodiment of the present invention, the connecting post is respectively disposed at the first conductive end 101 and the second conductive end 102 to realize the electrical connection between the two ends.

[0082] Furthermore, the connecting post 4 includes a nut and a plastic cap, the nut being connected to the first connecting end 101 and the second connecting end 102 by means of threaded connection or riveting.

[0083] This utility model also proposes a capacitor assembly having the above-described embodiments, the capacitor assembly including the aforementioned integrated magnetic ring assembly.

[0084] This utility model also proposes a motor controller 100 having the above-described embodiments, according to... Figure 7 As shown, the motor controller 100 includes the aforementioned integrated magnetic ring assembly and / or the aforementioned capacitor assembly.

[0085] Furthermore, the motor controller 100 also includes a power module 6, which can be a SiC module or an IGBT module. Its function is to receive direct current and invert it into alternating current to provide a power source for the motor rotation.

[0086] Furthermore, the motor controller 100 also includes a current sensor 5, one end of which is electrically connected to the aforementioned second conductive terminal 102, and the other end of which is electrically connected to the aforementioned power module 6, thereby enabling current monitoring and ensuring safety during normal use.

[0087] Furthermore, the motor controller 100 also includes a controller housing 1001 and a connector, which installs the integrated magnetic ring assembly into the motor controller 100 through the aforementioned mounting hole 32.

[0088] This utility model also proposes a powertrain having the above-described embodiments, particularly an EHS hybrid powertrain. The EHS hybrid powertrain may include a motor, which includes a three-phase winding; the first conductive end 101 of the aforementioned three-phase conductive copper busbar assembly 1 is electrically connected to the three-phase winding, and the second conductive end 102 is electrically connected to the power module 6 to realize a power supply circuit for the motor.
