[0053] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 8 A grounding conductive bar 10 according to an embodiment of the present invention is described. The grounding conductive bar 10 includes a conductive bar body 11 and at least one grounding spring piece 12 .

[0054] Specifically, if Figure 1-Figure 5As shown, the grounding spring piece 12 is provided on the conductive bar body 11, and the grounding spring piece 12 is an elastic member. In this embodiment, the number of the grounding spring pieces 12 is one or more, and the conductive bar body 11 included in the grounding conductive bar 10 is used to connect with the grounding spring piece 12. The grounding conductive bar 10 is suitable for being connected between the capacitor and the shell 50 of the filtering structure 100, wherein one end of the grounding conductive bar 10 is fixedly connected to the capacitor, and the other end of the grounding conductive bar 10 is elastically stopped against the shell 50. The conductive bar body 11 has a length direction, a width direction and a thickness direction, and the length direction, the width direction and the thickness direction are orthogonal to each other, wherein the size of the conductive bar body 11 along the length direction is respectively greater than the size along the width and thickness directions.

[0055] According to the grounding conductive bar 10 of the embodiment of the utility model, by setting the grounding spring sheet 12 on the grounding conductive bar 10, the grounding spring sheet 12 has elasticity, which can ensure that the grounding conductive bar 10 has a good grounding effect, improve the conduction effect of the filter structure 100 with the grounding conductive bar 10, so that the filter structure 100 has good anti-electromagnetic interference performance. At the same time, the elastic grounding spring sheet 12 can be used to absorb the tolerance and mechanical stress of the grounding conductive bar 10 during the assembly process, reduce the manufacturing accuracy requirements of the grounding conductive bar 10, and improve the assembly efficiency of the grounding conductive bar 10.

[0056] In some embodiments, Figure 5 As shown, the grounding spring piece 12 includes: an elastic connection part 121, at least one elastic deformation part 122, one end of the elastic connection part 121 is connected to the conductive bar body 11; the elastic deformation part 122 is connected to the other end of the elastic connection part 121. That is, the grounding spring piece 12 connected to the conductive bar body 11 includes the elastic deformation part 122, and when the grounding spring piece 12 is grounded, the elastic deformation part 122 stops against the "ground", and the "ground" here can refer to the shell 50 of the filter structure 100 in the following text. The shell 50 can be in contact with the ground or contact the ground through a wire to achieve indirect contact between the grounding spring piece 12 and the ground. When the elastic deformation part 122 stops against the ground, the elastic deformation part 122 is deformed to ensure that the grounding spring piece 12 is fully in contact with the ground and to ensure the reliability of the contact.

[0057] Optionally, there are multiple elastic deformation parts 122, and the multiple elastic deformation parts 122 are arranged at intervals along the length direction of the conductive bar body 11. There can be multiple elastic deformation parts 122, that is, one end of the multiple elastic deformation parts 122 is connected to the same elastic connection part 121, and the other end of the multiple elastic deformation parts 122 extends freely. The design of multiple elastic deformation parts 122 can increase the elasticity of the grounding spring 12, and can balance the mechanical force of the grounding spring 12 and the shell 50 to avoid excessive stress concentration when the grounding spring 12 contacts the shell 50, thereby increasing the service life of the grounding spring 12. For example, the elastic connection part 121 and the multiple elastic deformation parts 122 are formed into a claw-shaped structure.

[0058] In some embodiments, Figure 5-Figure 7 As shown, the elastic connecting portion 121 includes: a first side plate 1211, a connecting plate 1213, and a second side plate 1212. The first side plate 1211 extends along the width direction of the conductive bar body 11, and one end of the first side plate 1211 is connected to one side of the width direction of the conductive bar body 11; the connecting plate 1213 extends along the thickness direction of the conductive bar body 11, and one end of the connecting plate 1213 is connected to the other end of the first side plate 1211; one end of the second side plate 1212 is connected to the other end of the connecting plate 1213, the second side plate 1212 is opposite to the first side plate 1211 along the thickness direction of the conductive bar body 11, and the elastic deformation portion 122 is connected to the other end of the second side plate 1212.

[0059] That is, in this embodiment, the first side plate 1211 and the second side plate 1212 are parallel and oppositely arranged in the thickness direction of the conductive bar body 11, and a connecting plate 1213 is provided on the side of the first side plate 1211 and the second side plate 1212 away from the conductive bar body 11 along the width direction of the conductive bar body 11, which is used to connect the first side plate 1211 and the second side plate 1212 away from the conductive bar body 11. The end of the first side plate 1211 away from the connecting plate 1213 is connected to the conductive bar body 11, and the end of the second side plate 1212 away from the connecting plate 1213 is connected to the elastic deformation part 122, and the free end of the elastic deformation part 122 extends obliquely along the thickness direction of the conductive bar body 11 toward the direction away from the conductive bar body 11.

[0060] Thus, the provision of the elastic connection part 121 can increase the distance between the elastic deformation part 122 and the conductive bar body 11, avoiding interference of the conductive bar body 11 with the elastic deformation part 122 during deformation, and the elastic connection part 121 can further increase the elasticity of the grounding spring piece 12. It is also convenient for the grounding spring piece 12 to make at least part of the housing 50 located between the first side plate 1211 and the second side plate 1212 during installation, which facilitates the installation of the grounding conductive bar 10 in the filter structure 100 and improves the utilization rate of the internal space of the filter structure 100.

[0061] In some embodiments, Figure 5 As shown, a first through hole 1214 is formed on the second side plate 1212 to facilitate the installation of the grounding conductive bar 10 and improve the elastic deformation capability of the grounding conductive bar 10 .

[0062] In some embodiments, Figure 5 and Figure 7As shown, the elastic deformation portion 122 includes: a first elastic segment 1221 and a second elastic segment 1222. One end of the first elastic segment 1221 is connected to the other end of the elastic deformation portion 122 adjacent to the elastic connection portion 121, and the other end of the first elastic segment 1221 extends along the thickness direction of the conductive bar body 11 first toward a direction away from the conductive bar body 11 and then toward a direction close to the conductive bar body 11; one end of the second elastic segment 1222 is connected to the other end of the first elastic segment 1221 away from the elastic connection portion 121, and the other end of the second elastic segment 1222 extends in a direction away from the first elastic segment 1221 and in a direction away from the conductive bar body 11.

[0063] For example, in this embodiment, the first elastic segment 1221 and the second elastic segment 1222 are connected, and one end of the first elastic segment 1221 away from the second elastic segment 1222 is connected to one end of the elastic connection portion 121 away from the conductive bar body 11, and one end of the second elastic segment 1222 away from the first elastic segment 1221 extends obliquely in a direction away from the conductive bar body 11. The first elastic segment 1221 and the second elastic segment 1222 are respectively formed in an arc shape. The first elastic segment 1221 and the second elastic segment 1222 are designed in an S shape, and the arcs of the first elastic segment 1221 and the second elastic segment 1222 are raised in opposite directions, wherein the first elastic segment 1221 is raised in a direction away from the first side plate 1211, and the second elastic segment 1222 is raised in a direction toward the first side plate 1211. When the elastic deformation segment stops against the housing 50, it can be avoided that the end of the elastic deformation segment contacts the housing 50 or other components to cause stress concentration and damage to the housing 50 or other components. The arc-shaped first elastic segment 1221 and the second elastic segment 1222 can ensure that the elastic deformation part 122 is elastically deformed when subjected to force, reduce the friction between the elastic deformation part 122 and the shell 50, increase the deformation capacity of the elastic deformation part 122, and increase the service life of the elastic deformation part 122.

[0064] In some embodiments, there are multiple grounding springs 12, and the multiple grounding springs 12 are arranged at intervals along the length direction of the conductive bar body 11. As a result, the reliability of the grounding of the grounding springs 12 can be increased, so that the grounding conductive bar 10 is subjected to a balanced force. For example, in this embodiment, there are two grounding springs 12, and the two grounding springs 12 are respectively arranged at both ends of the length direction of the conductive bar body 11. As a result, the design of the two grounding springs 12 and the symmetrical distribution along the length direction of the grounding conductive bar 10 can effectively prevent the grounding springs 12 from being deformed, displaced, excessively bent or compressed during or after the assembly of the filter structure 100, thereby improving the reliability of the grounding conductive bar 10.

[0065] In some embodiments, a plurality of grounding springs 12 are evenly or irregularly spaced between the two ends of the length direction of the conductive bar body 11. That is, a plurality of grounding springs 12 are provided on the conductive bar body 11, and the plurality of grounding springs 12 can be spaced along the length direction, so as to improve the elasticity of the grounding conductive bar 10, help the reliability of the contact between the grounding conductive bar 10 and the housing 50, and increase the safety of use.

[0066] In some embodiments, a plurality of second through holes 111 are formed on the conductive bar body 11, and the plurality of second through holes 111 are arranged at intervals along the length direction of the conductive bar body 11, and at least one second through hole 111 is opposite to the grounding spring 12. The second through hole 111 can provide a mounting position for the capacitor to simplify the installation of the capacitor and the grounding conductive bar 10.

[0067] In some optional embodiments, the grounding conductive bar 10 is a beryllium copper member. Beryllium copper is an alloy material, a copper alloy with beryllium as the main alloying element, and is also called beryllium bronze. Beryllium copper has good conductivity, corrosion resistance, cold resistance, wear resistance, and non-magnetic properties, and is a relatively good elastic element with electromagnetic compatibility.

[0068] According to the filter structure 100 of the second embodiment of the utility model, Figure 8 The filtering structure 100 includes: at least one pair of Y capacitors, a grounding conductive bar 10, a positive conductive bar 30 and a negative conductive bar 40, wherein a conductive bar body 11 of the grounding conductive bar 10 is electrically connected to the Y capacitor at a side away from the grounding spring 12, and the grounding conductive bar 10 is the grounding conductive bar 10 of any one of the above embodiments; one end of one of the pair of Y capacitors is electrically connected to the positive conductive bar 30, the other end of the one of the pair of Y capacitors is electrically connected to the grounding conductive bar 10, one end of the other of the pair of Y capacitors is electrically connected to the negative conductive bar 40, and the other end of the other of the Y capacitors is electrically connected to the grounding conductive bar 10.

[0069] The filter structure 100 includes a negative conductive bar 40, a ground conductive bar 10 and a positive conductive bar 30 stacked in the height direction, that is, in the thickness direction of the ground conductive bar 10. When the filter structure 100 is assembled, the positive conductive bar 30 is arranged between the negative conductive bar 40 and the ground conductive bar 10, and the positive conductive bar 30 does not contact the negative conductive bar 40. The Y capacitor is a special capacitor, which is usually formed by two capacitors connected in opposite directions, and there is also a ground terminal in the middle, so it is also called a "differential mode capacitor" or a "capacitive differentiator". The function of the Y capacitor is mainly to filter out high-frequency noise in the signal, maintain the accuracy of the signal, and convert the signal between two different potential points into a differential signal, which is convenient for subsequent signal processing. In actual circuits, the function of the Y capacitor is mainly to suppress common-mode interference. It is connected between the live wire to the ground and the neutral wire to the ground. It usually appears in pairs to filter out common-mode noise and improve the anti-interference ability of the circuit.

[0070] In this embodiment, a pair of Y capacitors includes a first capacitor and a second capacitor, which are generally arranged in pairs. When the Y capacitors are installed, for example, one end of the first capacitor is connected to the positive conductive bar 30, the other end of the first capacitor is connected to the ground conductive bar 10, one end of the second capacitor is connected to the negative conductive bar 40, and the other end of the second capacitor is connected to the ground conductive bar 10. That is, one end of the two capacitors in the pair of Y capacitors is respectively connected to the ground conductive bar 10, and the other ends of the two capacitors are respectively connected to the positive conductive bar 30 and the negative conductive bar 40.

[0071] A pair of Y capacitors are arranged on the grounding conductive bar 10 and are located between the positive conductive bar 30 and the grounding conductive bar 10, that is, one end of two adjacent Y capacitors is electrically connected to the grounding conductive bar 10, and the other ends of the two Y capacitors are electrically connected to the positive conductive bar 30 and the negative conductive bar 40. When one of the two Y capacitors is connected to the positive conductive bar 30, it can directly stop on the positive conductive bar 30 to achieve electrical connection with the positive conductive bar 30, and when the other of the two Y capacitors is connected to the negative conductive bar 40, the pin of the other capacitor electrically connected to the negative conductive bar 40 can be extended toward the negative conductive bar 40 to achieve electrical connection with the negative conductive bar 40.

[0072] A plurality of pairs of Y capacitors may be provided in the filter structure 100 , and the plurality of pairs of Y capacitors are arranged at intervals in the filter structure 100 .

[0073] An accommodating cavity is defined between the positive electrode conductive bar 30 and the negative electrode conductive bar 40 . A plurality of capacitor cores 62 are disposed in the accommodating cavity. The plurality of capacitor cores 62 are electrically connected to the positive electrode conductive bar 30 and the negative electrode conductive bar 40 , respectively.

[0074] In some embodiments, Figure 1 and Figure 2As shown, the positive electrode conductive bar 30 includes at least one positive electrode input terminal 31 and at least one positive electrode output terminal 32, and the positive electrode input terminal 31 and the positive electrode output terminal 32 are respectively located on different sides of the positive electrode conductive bar 30. Therefore, by arranging the positive electrode input terminal 31 and the positive electrode output terminal 32 on both sides of the positive electrode conductive bar 30, respectively, and increasing the distance between the positive electrode input terminal 31 and the positive electrode output terminal 32, the electromagnetic interference between the positive electrode input terminal 31 and the positive electrode output terminal 32 can be greatly reduced, thereby ensuring the filtering effect of the capacitor.

[0075] The negative electrode conductive bar 40 includes at least one negative electrode input terminal 41 and at least one negative electrode output terminal 42, and the negative electrode input terminal 41 and the positive electrode input terminal 31 are respectively located on different sides of the negative electrode conductive bar 40. Therefore, by arranging the negative electrode input terminal 41 and the negative electrode output terminal 42 on both sides of the negative electrode conductive bar 40, respectively, and increasing the distance between the negative electrode input terminal 41 and the negative electrode output terminal 42, the electromagnetic interference between the negative electrode input terminal 41 and the negative electrode output terminal 42 can be reduced to a greater extent, thereby ensuring the filtering effect of the capacitor.

[0076] Furthermore, the positive input terminal 31 and the negative input terminal 41 are located on the same side of the filter structure 100, and the positive output terminal 32 and the negative output terminal 42 are located on the same side of the filter structure 100. This can avoid one output terminal and one input terminal of the positive conductive bar 30 and the negative conductive bar 40 being located on the same side, thereby avoiding electromagnetic interference between the positive conductive bar 30 and the negative conductive bar 40, and enhancing the filtering effect of the filter structure 100.

[0077] In some embodiments, the positive input terminal 31 and the negative input terminal 41 and the positive output terminal 32 and the negative output terminal 42 are respectively located on two opposite sides of the filter structure 100. In this embodiment, the positive input terminal 31 and the negative input terminal 41 are located on one side of the filter structure 100 along the first direction A, and the positive output terminal 32 and the negative output terminal 42 are located on the other side of the filter structure 100 along the first direction A. Therefore, the input terminal and the output terminal are respectively located on both sides of the filter structure 100 along a certain direction, which can increase the distance between the input terminal and the output terminal, reduce the electromagnetic interference between the input terminal and the output terminal, and improve the filtering effect.

[0078] The positive output terminal 32 and the negative output terminal 42 are stacked up and down along the second direction B, and are connected to the IGBT module (Insulated Gate Bipolar Transistor) by laser welding, or connected by fasteners such as bolts. Among them, the IGBT module is a composite fully controlled voltage-driven power semiconductor device composed of BJT (Bipolar transistor) and MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), which has the advantages of high input impedance of MOSFET and low conduction voltage drop of GTR, small driving power and low saturation voltage drop. Therefore, the positive output terminal 32 and the negative output terminal 42 are overlapped up and down, simplifying the assembly process and improving the assembly accuracy of the capacitor filter. The first direction A is perpendicular to the second direction B. The first direction A of the filter structure 100 is the width direction of the grounding conductive bar 10, and the second direction B of the filter structure 100 is the thickness direction of the grounding conductive bar 10.

[0079] Reference Figure 2 , the filter structure 100 also includes a ground input conductive bar 64 and a boost input conductive bar 65, that is, at least one pair of Y capacitors is provided at the input end, and the pair of Y capacitors at the input end is electrically connected to the ground input conductive bar 64. The ground conductive bar 10 is a ground output conductive bar in this embodiment. The ground input conductive bar 64 and the boost input conductive bar 65 are located on the same side of the first direction A as the positive input terminal 31 and the negative input terminal 41. The positive input terminal 31, the negative input terminal 41, the ground input conductive bar 64 and the boost input conductive bar 65 are respectively provided with connection fixing holes. The external high voltage power supply can be directly connected to the connection fixing holes of the positive input terminal 31 and the negative input terminal 41. The boost input conductive bar 65 is connected to the external boost circuit through the connection fixing holes provided thereon, and the ground input conductive bar 64 is fixed to the ground through the connection fixing holes provided thereon. In addition, setting a grounding point at the input end is conducive to reducing the electromagnetic interference of the capacitor filter.

[0080] In some embodiments, Figure 1As shown, the positive input terminal 31 and the negative input terminal 41 are both straight structures. The positive input terminal 31 and the negative input terminal 41 are straight structures, which can be understood as at least the positions of the positive input terminal 31 and the negative input terminal 41 for electrical connection are horizontal plate-like structures, and the two side surfaces of the positive input terminal 31 and the negative input terminal 41 in the thickness direction are arranged in parallel. For example, the positive input terminal 31 and the negative input terminal 41 are partially straight designs for realizing electrical connection with external devices. In this embodiment, the positive input terminal 31 and the negative input terminal 41 extend along the first direction A, wherein the positive input terminal 31 and the negative input terminal 41 pass through the shell 50 and extend out of the shell 50.

[0081] Therefore, the straight structures of the positive input terminal 31 and the negative input terminal 41 can simplify the structures of the positive conductive bar 30 and the negative conductive bar 40 , effectively reduce production costs, improve the production efficiency of the filter structure 100 , and reduce the production error of the filter structure 100 .

The plurality of mounting holes are respectively matched with the corresponding plurality of input terminals or input conductive bars. The grounding conductive bar 10 contacts the bottom wall of the housing 50 along the second direction B.

A limiting portion is provided on the bottom wall of the housing 50, and at least a portion of the grounding spring sheet 12 cooperates with the limiting portion, that is, the second elastic section 1222 of the elastic deformation portion 122 abuts against the limiting portion, so as to limit the displacement of the grounding conductive bar 10 in the first direction A when the grounding conductive bar 10 is subjected to force during the assembly process, ensure the elastic contact between the grounding spring sheet 12 and the housing 50, improve the accuracy of the filter structure 100 when it is assembled with the box body 200 of the controller below, and facilitate the effective grounding of the grounding spring sheet 12 and the box body 200.

[0086] In some embodiments, the heat conducting member 61 and the housing 50 are integrally formed, thereby simplifying the structure of the filter structure 100 and improving the assembly efficiency of the filter structure 100. In this embodiment, the heat conducting member 61 and the housing 50 are integrally formed by injection molding.

The capacitor core 62 is disposed in the housing 50 and between the positive conductive bar 30 and the negative conductive bar 40. The potting glue is disposed between the housing 50 and the capacitor core 62. For example, when each conductive bar, the capacitor core 62, etc. are assembled and loaded into the housing 50, the housing 50 is potted with a potting glue to fill and fix the capacitor core 62, the input conductive bar and the output conductive bar of the filter structure 100, and the ground conductive bar 10, etc., which can effectively prevent the internal components of the filter structure 100 from colliding and causing a short circuit, thereby improving the safety of the product. The potting glue is an epoxy glue.

[0088] Further, the filter structure 100 also includes: an insulating bracket 63, and the insulating bracket 63 is arranged between the positive conductive bar 30 and the negative conductive bar 40. The insulating bracket 63 is opposite to the grounding conductive bar 10 along the second direction B, and is located on both sides of the positive conductive bar 30 with the grounding conductive bar 10, and the positive conductive bar 30 and the negative conductive bar 40 are connected through the insulating bracket 63. The pins of the Y capacitor connected to the negative conductive bar 40 in a pair of Y capacitors pass through the insulating bracket 63 and are electrically connected to the negative conductive bar 40. In addition, the insulating bracket 63 has a positioning function, so that the positive conductive bar 30 and the negative conductive bar 40 can be installed smoothly, and the insulation between the positive conductive bar 30 and the negative conductive bar 40 is realized, and the positive conductive bar 30 and the negative conductive bar 40 are prevented from contacting and causing a short circuit.
