DETAILED DESCRIPTION

[0039] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0040] It should be understood that in the present disclosure, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "upper" and "lower" are defined based on the drawing directions shown in the corresponding drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific directional structure and operation, and therefore cannot be understood as a limitation on the present disclosure. The terms "inside" and "outside" can refer to the inside and outside of the corresponding structural contour. "First direction" and "second direction" can refer to Figure 2 , Figure 4 , Figure 5 In addition, it should be noted that the terms used, such as "first", "second", "third", "fourth", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0041] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "connected", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0042] As mentioned above, in the related technologies, the filter components are large in size and weight, which is not conducive to the miniaturization and lightness of the filter components and motor controllers. Especially after the motor controller adopts Sic power devices, the role of the input filter components is more obvious; the requirements for the motor controller to pursue small size, light weight, and high power density are becoming more and more urgent.

[0043] In view of this, if Figures 1 to 7 As shown, according to the first aspect of the present disclosure, there is provided a filter assembly 100, comprising a base 10, a conductive member 20 and a filter core 30, the base 10 comprising a shell 11 and a mounting member 13, the shell 11 being provided with a concave cavity 12, the mounting member 13 being mounted on the inner wall of the concave cavity 12, the mounting member 13 being provided with a through slot 131, one end of the through slot 131 extending to the outer wall of the shell 11, the filter core 30 being mounted in the concave cavity 12, and the filter core 30 being arranged around the mounting member 13, the conductive member 20 being arranged in the through slot 131 and passing through the filter core 30, that is, the filter core 30 being arranged around the conductive member 20.

[0044] In the present disclosure, one end of the conductive member 20 can be connected to the DC input side, and the other end can be connected to the connection side of the bus capacitor. When current is passed through the conductive member 20, since the filter core 30 is arranged around the conductive member 20, the inductive inductance when the current passes through the filter core 30 and the flow of high-frequency signals is hindered. When the current passes through the center of the filter core 30, due to the high magnetic permeability of the magnetic material, a higher inductive inductance is generated. This helps to reduce electromagnetic interference in the power supply and provide a more stable and reliable power output. When the filter component 100 is used for the input filter component 100 of the motor controller, it can prevent the peak current / peak voltage signal from being output to the outside.

[0045] In the present disclosure, the base 10 is used to fix other components on the filter assembly 100. A cavity 12 is designed on the base 10 to accommodate the filter core 30, and a mounting member 13 for mounting the conductive member 20 is passed through the shell 11 of the base 10, and a part of the mounting member 13 is also located in the cavity 12.

[0046] In this way, the filter core 30 and at least part of the mounting member 13 and at least part of the conductive member 20 are integrated and installed in the cavity 12 of the base 10. By rationally designing the structure of the cavity 12, the integration of the filter assembly 100 can be improved, which is beneficial to reducing the overall volume of the filter assembly 100 and achieving the purpose of small volume and lightweight of the filter assembly 100.

[0047] It is understandable that in the present disclosure, the filter component 100 can be applied not only to motor controllers, but also to any device that can use the filter component 100, such as photovoltaic inverters, high-power inverters and other high-voltage inverter products.

[0048] The base 10 may be a plastic base 10 , which can achieve lightweight of the filter assembly 100 and also provide insulation.

[0049] In the present disclosure, the conductive member 20 may include a positive conductive member 21 and a negative conductive member 22. The structure of the through slot 131 is not limited here. For example, the number of the through slot 131 may be single, and the positive conductive member 21 and the negative conductive member 22 can be placed in a single through slot 131 at the same time. The positive conductive member 21 and the negative conductive member 22 are provided with insulating members to isolate each other. As long as they can pass through the base 10 and can install the positive conductive member 21 and the negative conductive member 22, or, as Figure 2 and Figure 5 As shown, the through slot 131 may include a first through slot 1311 and a second through slot 1312, the positive electrode conductive member 21 is arranged in the first through slot 1311, and the negative electrode conductive member 22 is arranged in the second through slot 1312. Such a configuration can ensure that the positive electrode conductive member 21 and the negative electrode conductive member 22 do not affect each other, thereby ensuring insulation isolation between the positive electrode conductive member 21 and the negative electrode conductive member 22.

[0050] In the present disclosure, the first through slot 1311 and the second through slot 1312 are not limited in how they are formed. They can be formed as an integral part to form two first through slots 1311 and second through slots 1312 that can accommodate the positive electrode conductive member 21 and the negative electrode conductive member 22. They can also be formed by adding a separator 14 in the through slot 131. Figure 4 and Figure 5 As shown, the mounting member 13 may include an isolation plate 14, the isolation plate 14 includes a main body, a first extension portion 141 and a second extension portion 142, the main body is arranged in the through slot 131 to separate the through slot 131 into a first through slot 1311 and a second through slot 1312, the first extension portion 141 and the second extension portion 142 are arranged at both ends of the main body in a first direction, the first direction is consistent with the extension direction of the conductive member 20, and the positive conductive member 21 has a first section 21 located outside the first through slot 1311 1 and the second section 212, the negative electrode conductive member 22 has a third section 221 and a fourth section 222 located outside the second through slot 1312, the first extension portion 141 is located between the first section 211 and the third section 221, and the length of the first extension portion 141 is not less than the length of the first section 211 and the length of the third section 221, the second extension portion 142 is located between the second section 212 and the fourth section 222, and the length of the second extension portion 142 is not less than the length of the third section 221 and the length of the fourth section 222. The function of the separator 14 is to separate the positive electrode conductive member 21 and the negative electrode conductive member 22 to ensure that the creepage distance between the two is met.

[0051] Among them, Figure 1 and Figure 3As shown, the first extension portion 141 and the second extension portion 142 are portions of the separator 14 protruding from the housing 11, the first segment 211 and the second segment 212 of the positive electrode conductive member 21, and the third segment 221 and the fourth segment 222 of the negative electrode conductive member 22 are portions protruding from the housing 11, and the first segment 211, the second segment 212, the third segment 221 and the fourth segment 222 all extend along the first direction, that is, the length direction of the first segment 211, the second segment 212, the third segment 221 and the fourth segment 222 can be Figure 1 The first direction shown. Among them, the first section 211, the third section 221 and the first extension portion 141 extend in the same direction, and the first extension portion 141 is provided at the middle position between the first section 211 and the third section 221 to isolate the first section 211 and the third section 221, and the middle position here refers to the position of the line connecting the first section 211 and the third section 221 in the second direction. Similarly, the second section 212, the fourth section 222 and the second extension portion 142 extend in the same direction, therefore, the second extension portion 142 is provided at the middle position between the second section 212 and the fourth section 222, and the middle position here refers to the position of the line connecting the second section 212 and the fourth section 222 in the second direction to isolate the second section 212 and the fourth section 222. In order to meet the electrical clearance and creepage distance of the positive conductive member 21 and the negative conductive member 22, as Figure 4 As shown, the length of the first extension portion 141 is not less than the length of the first section 211 and the length of the third section 221, and the length of the second extension portion 142 is not less than the length of the third section 221 and the length of the fourth section 222, where the length refers to the dimension in the first direction.

[0052] In the present disclosure, the structure of the cavity 12 is not limited. The cavity 12 may have one opening surface or multiple opening surfaces, as long as its structure can accommodate the filter core 30. Figure 5 As shown, the concave cavity 12 can be set to be open at one end in the first direction, and the mounting member 13 is mounted on the inner side of the other end of the concave cavity 12 in the first direction, wherein the first direction is consistent with the extension direction of the conductive member 20. That is, the mounting member 13 is pierced on the inner wall of the concave cavity 12 opposite to the opening direction, and the opening direction of the concave cavity 12 is consistent with the extension direction of the conductive member 20, and the filter core 30 is also accommodated in the concave cavity 12, so that the conductive member 20, the mounting member 13 and the filter core 30 are integrated and installed, which is conducive to reducing the volume of the filter assembly 100.

[0053] In this disclosure, Figure 4 As shown, the filter component 100 may also include a capacitor 50. The base 10 is also provided with a groove 15 with an opening facing upward. The capacitor 50 is installed in the groove 15. The conductive member 20 is grounded through the capacitor 50, which can play a role in further filtering. At the same time, the grounding can protect the circuit.

[0054] A grounding conductive member 40 may be provided on the base 10 , and the grounding conductive member 40 is connected to the grounding end of the capacitor 50 to complete grounding.

[0055] Here, the capacitor 50 may be a safety capacitor, which can further filter the power supply and filter common-mode and differential-mode interference. There is no restriction on the structure and appearance of the safety capacitor.

[0056] In this disclosure, Figure 5 As shown, the mounting member 13 includes a separator 14 disposed in the through slot 131, and the number of the grooves 15 may be two, and the two grooves 15 are arranged at intervals along the second direction, and the two grooves 15 are respectively located on both sides of the separator 14 in the second direction, wherein the second direction is perpendicular to the extension direction of the conductive member 20. The number of the capacitors 50 may also be two, and each capacitor 50 is mounted in the corresponding groove 15, and the conductive member 20 includes a positive conductive member 21 and a negative conductive member 22, and the positive conductive member 21 and the negative conductive member 22 are respectively located on both sides of the separator 14 in the second direction, that is, in the second direction, the separator 14 is located between the positive conductive member 21 and the negative conductive member 22, and the positive conductive member 21 is grounded through one of the capacitors 50, and the negative conductive member 22 is grounded through the other capacitor 50. In order to make the arrangement position of the capacitor 50 highly integrated with the above-mentioned conductive component 20, the groove 15 is provided on both sides of the isolation plate 14, and the above-mentioned positive conductive component 21 and negative conductive component 22 are also installed on both sides of the isolation plate 14, so that the arrangement position of the two capacitors 50 can be conveniently connected to the positive conductive component 21 and the negative conductive component 22 respectively.

[0057] The two grooves 15 can be arranged symmetrically in the second direction compared to the isolation plate 14, so as to facilitate the connection between the capacitor 50 and the corresponding conductive member 20. In addition, the symmetrical arrangement can also make the structure of the filter component 100 compact and the layout reasonable.

[0058] In some embodiments, the number of the grounding conductive members 40 may be two, and the two grounding conductive members 40 are located on the base 10 close to the groove 15 , so that each conductive member 40 is conveniently connected to the corresponding capacitor 50 .

[0059] In the present disclosure, in order to facilitate the connection of capacitor 50, as shown in FIG. Figure 1 As shown in FIG. 1 , both the positive conductive member 21 and the negative conductive member 22 may be provided with a connecting branch 23 , wherein the connecting branch 23 of the positive conductive member 21 connects the capacitor 50 of the two capacitors 50 that is close to the positive conductive member 21 , and the connecting branch 23 of the negative conductive member 22 connects the capacitor 50 of the two capacitors 50 that is close to the negative conductive member 22 .

[0060] In the present disclosure, how the conductive member 20 is installed on the base 10 is not limited. Since the positive conductive member 21 and the negative conductive member 22 are inserted into the first groove 15 and the second groove 15, the positions of the positive conductive member 21 and the negative conductive member 22 have been limited. In order to make the installation of the positive conductive member 21 and the negative conductive member 22 more stable, the filter assembly 100 may also include at least two first fasteners 163.

[0066] In this disclosure, Figure 3As shown, the boosting conductive member 60 is disposed on one side of the base 10 in the second direction, and the second direction is perpendicular to the extension direction of the conductive member 20. This arrangement can effectively reduce the space formed by the boosting conductive member 60 and the conductive member 20, thereby reducing the volume of the entire filter assembly 100.

[0067] Alternatively, if Figure 1 and Figure 3 As shown, the boosting conductive member 60 may be arranged to be perpendicular to the bottom surface of the base 10 .

[0068] In this disclosure, Figure 3 and Figure 4 As shown, the boost conductor 60 can be detachably mounted on the base 10. By mounting the boost conductor 60 on the base 10 ( Figure 3 As shown) or remove the boost conductor 60 from the base 10 ( Figure 4 As shown), a solution that is compatible or incompatible with the boost conductive member 60 (Boost copper busbar) can be implemented; it can not only meet the filtering requirements of the DC input, but also meet the filtering requirements of the (Boost) boost conductive member 60 after the motor controller is equipped with the (Boost) boost function, thereby improving the versatility of the filter component 100 provided in the present disclosure.

In addition, a more compact layout design is adopted to achieve small size and light weight.

[0077] Here, combined with the Figure 2 , briefly state the assembly process of the filter components:

[0078] First, the base 10 can be produced by integrally forming with a mold. Since the base 10 has a simple structure and does not include plastic-coated conductive parts 20 (such as power copper busbar components such as the positive conductive parts 21 and the negative conductive parts 22), the mold cost is relatively low. The filter core 30 is installed, and the encapsulation process of the filter core 30 is completed. Subsequently, the positive conductive parts 21 and the negative conductive parts 22 are installed on the base 10, and the positive conductive parts 21 and the negative conductive parts 22 are fixed to the base 10 using the first fastener 163. Subsequently, the capacitor 50 is installed, and the capacitor 50 is connected to the corresponding positive conductive parts 21, negative conductive parts 22 and grounding conductive parts, and welding can be used at the connection points. Finally, according to the needs, it is selected whether to install the boost conductive part 60 to complete the installation of the entire filter component 100.
