However, during the boosting process, high-intensity electromagnetic interference is generated, which is conducted and radiated to other high and low voltage circuits through the boost port, thereby affecting the vehicle's EMC (Electromagnetic Compatibility) performance. Utility Model Content

[0003] The purpose of this utility model is to provide a high-voltage step-up distribution box, which aims to solve the problem that existing high-voltage step-up distribution boxes generate high-intensity electromagnetic interference during the step-up process, affecting the electromagnetic compatibility performance of the whole vehicle; another purpose of this application is to provide an automobile.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0023] Please refer to the following: Figures 1-5 This application provides a high-voltage step-up distribution box, including a housing 100, a step-up interface 200, a first filter conductor 300, a relay 400, and a first filter assembly 500. The housing 100 has a receiving cavity 110. The step-up interface 200 is connected to the housing 100 and is partially disposed within the receiving cavity 110. The first filter conductor 300 is disposed within the receiving cavity 110 and is electrically connected to the step-up interface 200. The relay 400 is disposed within the receiving cavity 110 and includes a first contact 410 and a second contact 420. The first contact 410 is electrically connected to the end of the first filter conductor 300 away from the step-up interface 200. The first filter assembly 500 is disposed within the receiving cavity 110. One end of the first filter assembly 500 is electrically connected to the second contact 420, and the other end of the first filter assembly 500 is connected to the housing 100.

[0024] In this embodiment, by connecting a first filter conductor 300 to the first contact 410 of a relay 400 at the boost interface 200, and then connecting a first filter assembly 500 to the second contact 420 of the relay 400, effective filtering is achieved at both ends of the relay 400 at the boost interface 200 through the cooperation of the first filter conductor 300 and the second filter conductor 700. This effectively reduces electromagnetic interference during the boost process and improves the electromagnetic compatibility performance of the entire vehicle. Furthermore, the first filter conductor 300 of this application can both transmit electrical signals between the boost interface 200 and the relay 400 and perform filtering. Its overall structure is simple and easy to assemble into a high-voltage boost distribution box on the production line.

[0025] Specifically, the high-voltage boost distribution box in this embodiment is equipped with a first filter conductor 300 and a first filter component 500. The first filter conductor 300 is electrically connected to the boost interface 200, which can initially filter the electromagnetic interference transmitted from the boost interface 200. One end of the first filter component 500 is connected to the second contact 420 of the relay 400 (the first contact 410 is connected to the boost interface 200 through the first filter conductor 300), and the other end is connected to the housing 100, forming a complete filtering path, which can further filter the remaining electromagnetic interference after the first filter conductor 300 has filtered it. Through the cooperation of these two structures, the electromagnetic interference generated during the boost process can be effectively filtered out, preventing it from being conducted to other high and low voltage circuits through the boost interface 200, thereby solving the problem of electromagnetic interference generated by the boost electrode affecting the EMC performance of the whole vehicle and improving the electromagnetic compatibility of the whole vehicle.

[0026] In addition, the boost interface 200, the first filter conductor 300, the relay 400 and the first filter component 500 are all housed in the housing 100 with the receiving cavity 110. This layout facilitates the conductive connection between the components and ensures the normal conduction of the circuit. On the other hand, the housing 100 can protect the internal components to a certain extent, prevent external factors from damaging the components, and also help to shield electromagnetic interference, further improve the EMC performance of the whole vehicle, and optimize the overall function of the high-voltage boost distribution box.

[0027] Meanwhile, this high-voltage boost distribution box can effectively connect charging piles of different voltage levels with high-voltage new energy vehicles. The stable boost process and effective suppression of electromagnetic interference ensure that vehicles can charge normally and efficiently when using charging piles of different voltage levels. This meets the needs of users in various charging environments and improves the adaptability and versatility of new energy vehicle charging. For example, the high-voltage boost distribution box in this embodiment can be used to meet the usage scenario of 800V new energy vehicles being compatible with both 400V and 800V charging piles.

[0028] It should be noted that different filtering structures can effectively handle electromagnetic interference (EMI) in different frequency bands. Essentially, the first filter conductor 300 filters interference in one frequency band, while the first filter component 500 can supplement the filtering of EMI by the first filter conductor 300, thus achieving a better EMI filtering effect. For example, the first filter conductor 300 can primarily filter high-frequency interference, while the first filter component 500 can focus on processing low-frequency interference. This significantly improves the overall EMI filtering capability and more comprehensively protects the vehicle's EMC performance.

[0029] Please refer to the following: Figures 5-7In some embodiments, the first filter conductor 300 includes a first conductor 310, a first filter half-ring 320, and a second filter half-ring 330. The first conductor 310 is electrically connected to the boost interface 200 and the first contact 410, respectively. The first filter half-ring 320 has a first groove 321, and a portion of the first conductor 310 is disposed in the first groove 321. The first filter half-ring 320 is connected to the first conductor 310. The second filter half-ring 330 has a second groove 331, and a portion of the first conductor 310 is disposed in the second groove 331. The second filter half-ring 330 is connected to the first conductor 310. The first filter half-ring 320 and the second filter half-ring 330 are located between the boost interface 200 and the first contact 410. The first filter half-ring 320 and the second filter half-ring 330 are disposed opposite to each other on both sides of the first conductor 310 and form a first high-voltage magnetic ring 340.

[0030] In this embodiment, the first filter half-ring 320 and the second filter half-ring 330 are tightly connected to the first conductor 310 through the first groove 321 and the second groove 331, respectively, forming a first high-voltage magnetic ring 340. This structure can effectively filter electromagnetic interference signals transmitted through the first conductor 310. Simultaneously, by combining two filter half-rings and connecting them to the first conductor 310 to form a filter conductor, the assembly difficulty of the first filter conductor 300 is effectively reduced. Furthermore, by connecting the first conductor 310 with the first filter half-ring 320 and the second filter half-ring 330 to form an integrated structure, the number of components can be effectively reduced, making the junction box interior neater and facilitating simple and quick installation of the high-voltage boost junction box on the production line.

[0031] It should be noted that the first filter half-ring 320 has a first groove 321, and the second filter half-ring 330 has a second groove 331. The first groove 321 and the second groove 331 are used to accommodate the first conductor 310, thus forming a combination of the first filter half-ring 320 and the second filter half-ring 330 surrounding the outside of the first conductor 310, forming a first high-voltage magnetic ring 340. At this time, the first high-voltage magnetic ring 340 can effectively filter electromagnetic interference at the boost interface 200.

[0032] It should be noted that the first filter half-ring 320 can be half a high-voltage magnetic ring, and the second filter half-ring 330 can also be half a high-voltage magnetic ring. The two work together to form the first high-voltage magnetic ring 340, which effectively filters the electromagnetic interference conducted at the first conductor 310. The first conductor 310 is preferably a copper busbar.

[0033] like Figure 8As shown, in some embodiments, the first filter component 500 includes a first Y capacitor 510 and a first circuit board 520. The first circuit board 520 includes a first plate body 521, a first connection terminal 522 and a second connection terminal 523. The first plate body 521 is connected to the first Y capacitor 510, the first connection terminal 522 and the second connection terminal 523 respectively. The first Y capacitor 510 is electrically connected to the first connection terminal 522 and the second connection terminal 523 respectively. The first connection terminal 522 is electrically connected to the second contact 420 and the second connection terminal 523 is connected to the housing 100.

[0034] In this embodiment, the first Y capacitor 510 has excellent common-mode interference suppression capability. It is electrically connected to the first connection terminal 522 and the second connection terminal 523 respectively, and can effectively filter out common-mode interference signals present in the circuit. By connecting it to the circuit, it works in conjunction with the previously mentioned first filter conductor 300 and other components, further improving the entire filtering system, suppressing electromagnetic interference in all aspects, greatly enhancing the electromagnetic compatibility of the entire vehicle, and ensuring the stable operation of electrical equipment in complex electromagnetic environments.

[0035] Meanwhile, the first circuit board 520 connects the first Y capacitor 510, the first connection terminal 522, and the second connection terminal 523 together through the first board body 521, forming a stable and efficient circuit connection structure. At this time, by fixing the first board body 521, the first connection terminal 522, the first Y capacitor 510, and the second connection terminal 523 exposed on the surface of the first board body 521 are used to realize signal transmission with the high and low voltage circuits, thereby achieving further filtering of battery interference.

[0036] Please refer to the following: Figures 2-4 , Figure 9 and Figure 11 In some embodiments, the high-voltage step-up distribution box further includes a charging interface 600, a second filter conductor 700, and a second filter assembly 800. The charging interface 600 is connected to the housing 100 and includes a third connection end 610 and a fourth connection end 620, which are located within the receiving cavity 110. The second filter conductor 700 is disposed within the receiving cavity 110, with one end of the second filter conductor 700 electrically connected to the second contact 420 and the other end of the second filter conductor 700 electrically connected to the third connection end 610. The second filter assembly 800 is disposed within the receiving cavity 110, with one end of the second filter assembly 800 electrically connected to the fourth connection end 620 and the other end of the second filter assembly 800 connected to the housing 100.

[0037] In this embodiment of the application, by setting a second filter conductor 700 and a second filter component 800 at the input and output ends of the charging interface 600, effective filtering at the charging interface 600 can be achieved, thereby further improving the overall anti-interference capability of the high voltage boost junction box and improving electromagnetic compatibility.

[0038] Specifically, the second filter conductor 700 connects the second contact 420 of the relay 400 to the third connection terminal 610 of the charging interface 600, ensuring stable transmission of electrical signals between the relay 400 and the charging interface 600. Simultaneously, it effectively filters the signal transmission process, reducing electromagnetic interference. The second filter component 800 connects one end to the fourth connection terminal 620 of the charging interface 600 and the other end to the housing 100, further filtering electromagnetic interference during the charging process. This ensures stable current and voltage at the charging interface 600, effectively preventing charging anomalies caused by electromagnetic interference and other factors, and ensuring that new energy vehicles can complete charging efficiently and stably.

[0039] like Figure 9 and Figure 10 As shown, in some embodiments, the second filter conductor 700 includes a second conductor 710, a third filter half-ring 720, and a fourth filter half-ring 730. The second conductor 710 is electrically connected to the boost interface 200 and the first contact 410, respectively. The third filter half-ring 720 has a third groove 721, and a portion of the second conductor 710 is disposed within the third groove 721. The third filter half-ring 720 is connected to the second conductor 710. The fourth filter half-ring 730 has a fourth groove 731, and a portion of the second conductor 710 is disposed within the fourth groove 731. The fourth filter half-ring 730 is connected to the second conductor 710. The third filter half-ring 720 and the fourth filter half-ring 730 are disposed between the relay 400 and the charging interface 600. The third filter half-ring 720 and the fourth filter half-ring 730 are disposed opposite to each other on both sides of the second conductor 710 and form a second high-voltage magnetic ring 740.

[0040] In this embodiment, the first filter half-ring 320 and the second filter half-ring 330 are tightly connected to the second conductor 710 through the third groove 721 and the fourth groove 731, respectively, forming a second high-voltage magnetic ring 740. This structure can effectively filter electromagnetic interference signals transmitted through the first conductor 310. Furthermore, by combining two filter half-rings with the first conductor 310 to form a filter conductor, the assembly difficulty of the second filter conductor 700 is effectively reduced. Additionally, the second conductor 710, by connecting with the third filter half-ring 720 and the fourth filter half-ring 730 to form an integrated structure, effectively reduces the number of components, making the junction box interior neater and facilitating simple and quick installation of the high-voltage boost junction box on the production line.

[0041] It should be noted that the third filter half-ring 720 has a third groove 721, and the fourth filter half-ring 730 has a fourth groove 731. The third groove 721 and the fourth groove 731 are used to accommodate the second conductor 710. Thus, the third filter half-ring 720 and the fourth filter half-ring 730 are arranged to surround the outside of the second conductor 710, forming a second high-voltage magnetic ring 740. At this time, the second high-voltage magnetic ring 740 can effectively filter electromagnetic interference at the charging interface 600.

[0042] It should be noted that the third filter half-ring 720 can be half a high-voltage magnetic ring, and the fourth filter half-ring 730 can also be half a high-voltage magnetic ring. The two work together to form the second high-voltage magnetic ring 740, which effectively filters the electromagnetic interference conducted at the second conductor 710. The second conductor 710 is preferably a copper busbar.

[0043] like Figure 7 and Figure 10 As shown, in some embodiments, the first filter half-ring 320 and the second filter half-ring 330 are spaced apart, and the third filter half-ring 720 and the fourth filter half-ring 730 are spaced apart.

[0044] In this embodiment, there is a gap between the first filter half-ring 320 and the second filter half-ring 330, and there is also a gap between the third filter half-ring 720 and the fourth filter half-ring 730. This ensures that there is sufficient magnetic flux between the two filter half-rings, thereby achieving a better filtering effect for the high-voltage magnetic ring.

[0045] In some embodiments, the first filter half-ring 320 and the second filter half-ring 330 are both glued to the first conductor 310; the third filter half-ring 720 and the fourth filter half-ring 730 are both glued to the second conductor 710.

[0046] In this embodiment, the filter half-ring and conductor are connected by adhesive bonding, which enables a quick and effective connection and fixation between the filter half-ring and the conductor, thereby improving production efficiency.

[0047] like Figures 5-7 , Figure 9 and Figure 10 In some embodiments, the first filter conductor 300 further includes a first insulating protective layer 350, which surrounds the outer periphery of the first filter half-ring 320, the second filter half-ring 330, and the first conductor 310, and is connected to the first filter half-ring 320, the second filter half-ring 330, and the first conductor 310, respectively; the second filter conductor 700 further includes a second insulating protective layer 750, which surrounds the outer periphery of the third filter half-ring 720, the fourth filter half-ring 730, and the second conductor 710, and is connected to the third filter half-ring 720, the fourth filter half-ring 730, and the second conductor 710, respectively.

[0048] In this embodiment, by providing the first insulating protective layer 350, a more effective and robust connection can be achieved between the first filter half-ring 320, the second filter half-ring 330, and the first conductor 310. By providing the second insulating protective layer 750, a more effective and robust connection can be achieved between the third filter half-ring 720, the fourth filter half-ring 730, and the second conductor 710, avoiding the failure of the connection between the conductor and the filter half-ring due to adhesive aging, or even the problem of the filter half-ring falling off, thus effectively ensuring the stability of the overall structure of the filter conductor.

[0049] Preferably, the first insulating protective layer 350 and the second insulating protective layer 750 can be insulating heat shrink tubing. After the heat shrink tubing is sleeved on the outside of the conductor and the filter half-ring, it can be firmly covered by heat shrinking, making the overall assembly more convenient. At the same time, there is no need to add a magnetic ring auxiliary installation structure, thus achieving a lower overall cost of the filter conductor.

[0050] like Figure 11 As shown, in some embodiments, the second filter component 800 includes a second Y capacitor 810 and a second circuit board 820. The second circuit board 820 includes a second plate body 821, a fifth connection terminal 822, and a sixth connection terminal 823. The second plate body 821 is connected to the second Y capacitor 810, the fifth connection terminal 822, and the sixth connection terminal 823, respectively. The second Y capacitor 810 is electrically connected to the fifth connection terminal 822 and the sixth connection terminal 823, respectively. The fifth connection terminal 822 is electrically connected to the fourth connection terminal 620, and the sixth connection terminal 823 is connected to the housing 100.

[0051] In this embodiment, a second Y capacitor 810 is also connected at the charging interface 600, which can effectively filter out common-mode interference signals present in the auxiliary circuit of the charging interface 600. Working in conjunction with the previously mentioned second filter conductor 700 and other components, the entire filtering system is further improved, comprehensively suppressing electromagnetic interference, greatly enhancing the electromagnetic compatibility of the entire vehicle, and ensuring stable operation of electrical equipment in complex electromagnetic environments.

[0052] Meanwhile, the second circuit board 820 connects the second Y capacitor 810, the fifth connection terminal 822, and the sixth connection terminal 823 together through the second board body 821. At this time, the second Y capacitor 810 is effectively fixed by directly fixing the first board body 521. The fifth connection terminal 822 and the sixth connection terminal 823 can be electrically connected to the second Y capacitor 810 through wires extending outside the first board body 521. This makes it easier to make the location of the second filter component 800 more flexible and facilitates the reasonable arrangement of the circuit inside the housing 100.

[0053] In some embodiments, the first filter conductor 300 and the first filter component 500 have different filter frequency bands, and / or the second filter conductor 700 and the second filter component 800 have different filter frequency bands.

[0054] In this embodiment, the first filter conductor 300 has a different filter frequency band than the first filter component 500, enabling more comprehensive filtering of the circuit near the boost interface 200; the second filter conductor 700 and the second filter component 800 have different filter frequency bands, enabling more comprehensive filtering of the circuit near the charging interface 600, thereby effectively improving the anti-interference capability of the high-voltage boost junction box and enhancing its electromagnetic compatibility performance.

[0055] Accordingly, this application also provides a vehicle that includes a high-voltage step-up distribution box as described in any of the foregoing embodiments.
