[0025] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] Currently, in many vehicle controllers, filters are needed to filter signals to reduce impurities in the signals. However, the current filters are relatively large in volume, occupy a large space in the vehicle controller, and are not easy to disassemble, install or replace. Based on the above requirements, while ensuring the filtering function of the filter, the present application provides a controller including a filtering mechanism 1000.

[0027] For the aforementioned filtering mechanism 1000, please refer to Figure 1 , the filtering mechanism 1000 includes a first filtering magnetic ring assembly 100, a second filtering magnetic ring assembly 200, a conductive bar assembly 300, a filtering board 400, and a plugging assembly 500.

[0028] In some embodiments, please refer to Figure 2 and Figure 3 , the first filtering magnetic ring assembly 100 is provided with a first through port 110 and a first limiting groove 120. The first through port 110 penetrates the first filtering magnetic ring assembly 100 along the first direction F1, and the first limiting groove 120 extends along the second direction F2.

[0029] In some embodiments, please refer toFigure 2 and Figure 3 The second filtering magnetic ring assembly 200 is provided with a second through port 210 and a second limiting groove 220. The second through port 210 penetrates the second filtering magnetic ring assembly 200 along the first direction F1, and the second limiting groove 220 extends along the second direction F2, wherein the first direction F1 and the second direction F2 are perpendicular to each other.

[0030] In some embodiments, please refer to Figure 2 and Figure 3 The conductive busbar assembly 300 sequentially passes through the first through port 110 and the second through port 210.

[0031] In some embodiments, please refer to Figure 2 and Figure 3 The plugging assembly 500 includes a first plug post 510 and a second plug post 520. Both the first plug post 510 and the second plug post 520 are disposed on the filtering plate 400. The first plug post 510 is plugged into the first limiting groove 120, and the second plug post 520 is plugged into the second limiting groove 220.

[0032] Combined with the above embodiments, the conductive busbar assembly 300 sequentially passes through the first through port 110 and the second through port 210 along the first direction F1, and the first filtering magnetic ring assembly 100 and the second filtering magnetic ring assembly 200 are also spaced apart and separately disposed along the first direction F1. Therefore, when the first filtering magnetic ring needs to be installed, disassembled or repaired and replaced, the first plug post 510 can be installed or disassembled between the first limiting groove 120 and the filtering plate 400; correspondingly, when the second filtering magnetic ring needs to be installed, disassembled or repaired and replaced, the second plug post 520 can be installed or disassembled between the second limiting groove 220 and the filtering plate 400. The two can be independently installed or disassembled, which improves the installability of the filtering mechanism 1000 on the one hand, improves the mobility of the filtering mechanism 1000 on the other hand, and improves the compatibility between the filtering mechanism 1000 and other devices on the third hand. Among them, the compatibility between the filtering mechanism 1000 and other devices means that through the split-type filtering mechanism 1000, the first filtering magnetic ring assembly 100 and the second filtering magnetic ring assembly 200 can be separately installed to adapt to controllers with different structural layouts, so as to improve the compatibility of the filtering mechanism 1000.

Among them, the conductive bar assembly 300 is a positive copper bar and a negative copper bar that are respectively connected to the positive and negative poles of the circuit. By providing the first plug post 510, the first limiting groove 120 and the first through hole 310 are aligned and installed, so that the installation between the conductive bar assembly 300 and the first filter magnetic ring assembly 100 is stable.

[0034] In some embodiments, please refer to Figure 2 and Figure 3 , the first plug post 510 includes a first column body 511 and a first plugging portion 5111.

[0035] In some embodiments, please refer to Figure 2 and Figure 3 , the number of the first plug posts 510 can be two to adapt to the two conductive copper bars of the positive and negative poles of the conductive bar assembly 300.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 , one end of the first column body 511 is arranged on the filter board 400, the other end of the first column body 511 extends with a first plugging portion 5111, the cross-section of the first plugging portion 5111 is smaller than the cross-section of the first column body 511, the first plugging portion 5111 passes through the first through hole 310 and extends into the first limiting groove 120, and the end surface of the other end of the first plugging portion 5111 abuts against the surface of the conductive bar assembly 300 facing the filter board 400. It is worth mentioning that "the cross-section of the first plugging portion 5111 is smaller than the cross-section of the first column body 511" means that the first plug post 510 is tapered, and the part of the first plugging portion 5111 passing through the first through hole 310 is in snap-fit with the first through hole 310, so that the conductive bar assembly 300 can be installed and fixed on the first column body 511, or the part of the first plugging portion 5111 passing through the first through hole 310 is in clearance fit with the first through hole 310, thereby restricting the movement of the conductive bar assembly 300; on the other hand, the larger cross-section on the side close to the filter board 400 can further enhance the stability of the first plug post 510.

[0037] In some embodiments, please refer to Figure 2 and Figure 3 , the first column body 511 is screwed to the filter board 400 by bolts, and the bolts pass through the filter board 400 to be screwed to the inside of the first column body 511, thereby enhancing the installation stability of the first column body 511.

It is worth mentioning that the first column cap 512 can be screwed, clamped, or sleeved on the first plug-in portion 5111. The outer surface of the first column cap 512 is a polygonal surface, thereby increasing the friction resistance between the first column cap 512 and the first limiting groove 120, and preventing the first column cap 512 and the first limiting groove 120 from having relative movement.

[0041] In some embodiments, see Figure 2 and Figure 3 The first column cap 512 and the first column body 511 are clamped together on both sides of the first through hole 310 , thereby improving the installation stability between the conductive bar assembly 300 and the first plug column 510 .

[0044] In some embodiments, see Figure 2 and Figure 3 The number of the second plug posts 520 can be two to adapt to the two conductive copper bars of the positive and negative electrodes of the conductive bar assembly 300 .

The cross-section of the second plug-in portion 5211 is smaller than the cross-section of the second column 521. The second plug-in portion 5211 passes through the second through hole 320 and extends into the second limiting groove 220. The end face of the other end of the second plug-in portion 5211 abuts against the surface of the conductive row assembly 300 facing the filter plate 400. It is worth mentioning that “the cross-section of the second plug-in portion 5211 is smaller than the cross-section of the second column 521” means that the second plug-in portion 520 is arranged in a conical shape, and the portion of the second plug-in portion 5211 that passes through the second through hole 320 is snap-fitted with the second through hole 320, so that the conductive row assembly 300 can be installed and fixed to the second column 521, or the portion of the second plug-in portion 5211 that passes through the second through hole 320 is gap-fitted with the second through hole 320, thereby limiting the movement of the conductive row assembly 300; on the other hand, the larger cross-section on the side close to the filter plate 400 can further enhance the stability of the second plug-in portion 520.

[0046] In some embodiments, see Figure 2 and Figure 3 The second column 521 is screwed to the filter plate 400 by bolts, and the bolts pass through the filter plate 400 to be screwed to the inside of the second column 521, thereby enhancing the installation stability of the second column 521.

It is worth mentioning that the second column cap 522 can be screwed, clamped, or sleeved on the second plug-in portion 5211. The outer surface of the second column cap 522 is a polygonal surface, thereby increasing the friction resistance between the second column cap 522 and the second limiting groove 220, and preventing the second column cap 522 and the second limiting groove 220 from having relative movement.

By providing the first annular partition 142 and the first extension portion 143, the first magnetic ring 130 is shielded, reducing the phenomenon that impurities in the air are adsorbed on the surface of the first magnetic ring 130 under the influence of the magnetic field; and shielding at least part of the conductive bar assembly 300, reducing the impurities in the air from falling on the surface of the conductive bar assembly 300 and reducing the conductivity of the conductive bar assembly 300. It can be understood that, in order to reduce the height of the first filtering magnetic ring assembly 100 in the second direction F2 and further reduce the volume of the filtering mechanism 1000, the first magnetic ring 130 is arranged in an approximately flat shape, but due to its own requirements for the magnetic field, the first magnetic ring 130 is arranged in a structure with a thickness. It still needs to be noted that the first limiting groove 120 is provided on the first annular partition 142, and a blocking wall is also provided between the first annular partitions 142 to separate the two first limiting grooves 120, thereby increasing the spacing distance between the two first column caps 512 and improving the circuit safety.

It can be understood that, in order to reduce the height of the second filter magnetic ring assembly 200 in the second direction F2 and thus reduce the volume of the filtering mechanism 1000, the second magnetic ring 230 is arranged in an approximately flat shape. However, due to its own requirements for the magnetic field, the second magnetic ring 230 is arranged in a structure with a thickness. It should still be noted that the second limiting groove 220 is provided on the second annular partition 242, and a blocking wall is also provided between the second annular partitions 242 to separate the two second limiting grooves 220, thereby increasing the spacing distance between the two second stud caps 522 and improving the circuit safety.
