DETAILED DESCRIPTION

[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0040] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] According to a first embodiment of the present application, a filter bracket is provided. The filter bracket comprises a housing, wherein the housing is provided with an accommodating cavity for accommodating a first filter component and a second filter component.

[0044] like Figure 6 As shown, the shell is made of metal, polymer material, ceramic, etc. In the case of metal, conductive ceramic, carbon fiber, etc., the filter bracket can also effectively perform electromagnetic shielding.

[0045] In the embodiment of the present application, the filter bracket includes a housing having a housing for accommodating a first filter assembly and a second filter assembly. The filter bracket can integrate multiple filter assemblies together so that they can be installed as a whole, reduce the assembly process of the whole machine, improve the space utilization rate of the filter, and solve the problem of poor high-frequency filtering characteristics.

[0046] In an example, the accommodating cavity includes a first accommodating cavity 121 and a second accommodating cavity 122 which are stacked, the first filter component is located in the first accommodating cavity 121 , and the second filter component is located in the second accommodating cavity 122 .

[0047] like Figure 6 As shown, the first accommodating cavity 121 is located above the second accommodating cavity 122. A partition 124 is provided between the two accommodating cavities. For example, the housing is formed by injection molding or casting. This method can significantly improve the space utilization of the housing.

[0048] In one example, the first accommodating cavity 121 has a first opening, and the first opening is suitable for loading and removing the first filter component.

[0049] like Figure 2 , Figure 6 As shown, the first opening of the first accommodating cavity 121 faces leftward along the X-axis. During installation, the first filter assembly faces rightward along the X-axis and enters the first accommodating cavity 121 through the first opening. This makes it easy to assemble the first filter assembly.

[0050] Of course, the opening direction of the first opening is not limited here, and those skilled in the art can set it according to actual needs.

[0051] In one example, the second accommodating cavity 122 has a second opening, and the second opening is suitable for loading and removing the second filter assembly. The first opening and the second opening have different opening directions.

[0052] like Figure 6 and Figure 2 As shown, the first filter assembly and the second filter assembly are installed in their respective accommodating cavities through the openings of their respective accommodating cavities. The first opening direction of the first accommodating cavity 121 is to the left along the X-axis. The second opening direction of the second accommodating cavity 122 is downward along the Z-axis. During installation, the first filter assembly moves to the right along the X-axis and enters the first accommodating cavity 121 through the first opening. The second filter assembly moves upward along the Z-axis and enters the second accommodating cavity 122 through the second opening. This arrangement allows the installation of the first filter assembly and the second filter assembly to not interfere with each other, thereby facilitating the assembly of the filter module.

[0053] In one example, the housing further includes a third accommodating cavity 123 , which is located on the same side of the first accommodating cavity 121 and the second accommodating cavity 122 , and is suitable for accommodating an inductor element.

[0054] like Figure 6 , Figure 2 and Figure 3 As shown, the inductor element includes a first inductor element 1 and a second inductor element 11. The axial directions of the first inductor element 1 and the second inductor element 11 are parallel to the X-axis and are stacked, which makes the first inductor element 1 and the second inductor element 11 larger in the Z-axis direction. The two inductors are located on the same side of the first filter component and the second filter component, and the size in the Z-axis direction is reduced by increasing the size in the X-axis direction, which makes the space utilization rate of the filter component higher.

[0055] Correspondingly, the housing 12 includes a third accommodating cavity 123. The third accommodating cavity 123 includes a first sub-cavity for accommodating the first inductor element 1 and a second sub-cavity for accommodating the second inductor element 11. The first sub-cavity and the second sub-cavity are both annular. The first sub-cavity is arranged around the upper through hole 1231. The second sub-cavity is arranged around the lower through hole 1232. The upper through hole 1231 and the lower through hole 1232 are used to avoid other components, such as the conductive element 13. The third accommodating cavity 123 is located on the same side of the first accommodating cavity 121 and the second accommodating cavity 122, so as to adapt to the installation of the first inductor element 1 and the second inductor element 11, and play a supporting role for the first inductor element 1 and the second inductor element 11.

[0056] In one example, the third accommodating cavity 123 has a third opening, the opening direction of the third opening is different from the opening direction of the first opening, and / or

[0057] An opening direction of the third opening is different from an opening direction of the second opening.

[0058] like Figure 5 , Figure 2 and Figure 3 As shown, the third opening of the third accommodating cavity 123 is rightward along the X-axis. During installation, the first inductor element 1 and the second inductor element 11 are moved leftward along the X-axis and enter the third accommodating cavity 123. In this way, the installation of the components in the three accommodating cavities can be carried out without interfering with each other, thereby facilitating the installation of the filter module.

[0059] Of course, the opening directions of the first accommodating cavity 121, the second accommodating cavity 122, and the third accommodating cavity 123 are not limited to the above embodiments. The third opening direction of the third accommodating cavity 123 may also be upward along the Z axis. Those skilled in the art may set it according to actual needs.

[0060] In the related art, the controller is provided with multiple filter devices, which are scattered in different positions of the controller and integrated with other components such as busbar support capacitors. Although this setting method reduces the assembly process, the potting glue process usually used during integration will cover the entire filter circuit, thereby greatly increasing the distributed capacitance between the various components of the filter circuit, resulting in strong high-frequency EMI of the controller and unable to effectively filter out the high-frequency interference signal of the controller.

[0061] According to a second embodiment of the present application, a filter module is provided, which includes a first filter component, a second filter component and the above-mentioned filter bracket, wherein the first filter component and the second filter component are located in the accommodating cavity.

[0062] In this example, the filter module is an independently set device, which does not need to be integrated with other devices and does not need to be potted. In this way, the distributed capacitance between various devices can be effectively reduced, and the high-frequency interference signal of the controller can be effectively reduced. The high-frequency filtering characteristics of the filter module are good.

[0063] In one example, the first filter component and the second filter component are stacked; the input end of the filter module is suitable for connecting to a power distribution component.

[0064] like Figure 2 , Figure 3 As shown, the first filter assembly is located in the first accommodating cavity 121. The second filter assembly is located in the second accommodating cavity 122. The first filter assembly is stacked above the second filter assembly. The filter module is an independently arranged functional device for filtering electromagnetic interference. In this way, the space utilization rate of the filter module can be significantly improved, the filter module occupies a small space, and can be installed more easily.

[0065] In addition, the power distribution component forms a power distribution branch. The power distribution component is used to supply power to external devices. In this example, when the noise signal is transmitted inward, it must first be attenuated by the filter component and then transmitted along the power distribution component. Due to the effect of the filter component, the noise signal has been attenuated, thereby greatly reducing the noise signal transmitted along the power distribution component.

[0066] In one example, the first filter assembly is suitable for connecting to the input end 2 of the filter module, and the first filter assembly includes a first mounting portion 4 and a first filter component, and the first filter component is arranged on the first mounting portion 4. The second filter assembly is suitable for connecting to the output end 9 of the filter module, and the first filter assembly includes a second mounting portion 7 and a second filter component, and the second filter component is arranged on the second mounting portion 7, and the first filter assembly is stacked above the second filter assembly.

[0067] Specifically, if Figures 1 to 3As shown, the filter module is used to filter the high-voltage DC circuit. For example, the filter module can filter out electromagnetic interference in the high-voltage DC circuit, such as high-frequency electromagnetic interference. The first filter component and the second filter component include at least one of a capacitor, an inductor, a resistor, a bipolar tube, a unipolar tube, an integrated operational amplifier, etc. The first mounting portion 4 is used to fix the first filter component. The second mounting portion 7 is used to fix the second filter component. For example, the first mounting portion 4 and the second mounting portion 7 are mounting plates. Optionally, the mounting plate includes a metal plate, a ceramic plate, a plastic plate, a printed circuit board, etc. The first filter component is fixed to the first mounting portion 4 by bonding, welding, bolting, etc. The second filter component is fixed to the second mounting portion 7 by bonding, welding, bolting, etc. The conductive element 13 is used for conducting electricity, for example, the conductive element 13 includes a positive conductive bar and a negative conductive bar. The materials of the above two conductive bars are copper, aluminum, stainless steel, etc. The input end 2 of the positive conductive bar and the negative conductive bar is used to connect to the high-voltage terminal of an external device (for example, a battery pack). The input end 2 of the conductive element 13 is the input end of the filter module. The output end 9 of the conductive element 13 is used to connect to an electrical device. The output end 9 of the conductive element 13 is the output end of the filter module.

[0068] In this example, the filter module is an independently arranged functional device for filtering electromagnetic interference. The first filter component is stacked on the second filter component. In this way, the space utilization of the filter module can be significantly improved, the filter module occupies a small space, and can be installed more easily.

[0069] In addition, the first filter component is suitable for connecting to the input end 2 of the conductive element 13. The second filter component is suitable for connecting to the output end 9 of the conductive element 13. This arrangement makes the filter module have a better filtering effect on electromagnetic interference.

[0070] Of course, the filter module is not limited to two filter components, and 3, 4, 5 or more filter components may be provided. A plurality of filter components may be stacked in a group to improve the space utilization of the filter module.

[0071] In one example, the filter module further includes an inductor element, and the inductor element is located on the same side of the first filter component and the second filter component.

[0072] like Figures 2 to 4 As shown, the inductor element is suitable for connecting to the middle of the conductive element 13. The inductor element is located in the third accommodating cavity 123. The inductor element is located on the same side of the first filter assembly and the second filter assembly. This makes the space utilization rate of the filter module high and the space occupied by the filter module small.

[0073] In one example, the inductor element includes a first inductor element 1 and a second inductor element 11 , wherein the axes of the first inductor element 1 and the second inductor element 11 are parallel and stacked.

[0074] like Figure 2 , Figure 3 As shown, the first inductance element 1 and the second inductance element 11 both include a magnetic ring. When in use, the magnetic ring is sleeved outside the conductive element 13. The first inductance element 1 and the second inductance element 11 are suitable for connecting with the conductive element 13. The first inductance element 1 and the second inductance element 11 are located on the same side of the first filter component and the second filter component. The first filter component, the second filter component, the first inductance element 1 and the second inductance element 11 work together to more effectively filter electromagnetic interference. The axes of the first inductance element 1 and the second inductance element 11 are parallel and stacked, which makes the space utilization rate of the filter module high and the space occupied by the filter module small.

[0075] In one example, the first filter component and / or the second filter component includes a capacitive device.

[0076] like Figures 2 to 3 As shown, the capacitor device includes an X capacitor and a Y capacitor. The Y capacitor is used to connect the ground wire and the conductive element 13. The X capacitor is used to connect the positive conductive row and the negative conductive row.

[0077] X capacitors are mainly used to filter out differential mode noise signals, for example, to prevent a sudden increase in current from causing damage to the circuit, thereby protecting the stability and reliability of the circuit.

[0078] Y capacitors are mainly used to filter out common-mode noise signals and protect controllers from fault voltages and transient events in the power supply. For example, Y capacitors can quickly absorb and release electrical energy, thereby protecting controllers from overvoltage and overcurrent damage. Y capacitors are commonly used for power isolation, power protection, and surge protection, etc.

[0079] Of course, those skilled in the art can select the X capacitor and the Y capacitor according to actual needs, and this application does not limit this.

[0080] In one example, the first filter device includes a first capacitive device and a second capacitive device, and at least one of the first capacitive device and the second capacitive device is suitable for being connected to the input terminal 2 of the filter module.

[0081] like Figures 2 to 3 As shown, the first capacitive device includes a first Y capacitor 14. The first Y capacitor 14 is fixed to the first mounting portion 4. The second capacitive device includes a second Y capacitor 15 and a first X capacitor 19. The second Y capacitor 15 and the first X capacitor 19 are fixed to the first mounting portion 4. The first mounting portion 4 is provided with a first grounding device.

[0082] like Figure 4 As shown, the first Y capacitor includes capacitor CY1 and capacitor CY5. One end of capacitor CY1 is connected to the input end 2 of the negative electrode conductive bar through a first connecting copper pillar 3, and the other end is connected to the first grounding device of the first mounting portion 4. One end of capacitor CY5 is connected to the input end 2 of the positive electrode conductive bar through another first connecting copper pillar 3, and the other end is connected to the first grounding device of the first mounting portion 4. The first X capacitor 19 includes capacitor CX1. The two ends of capacitor CX1 are respectively connected to the positive electrode conductive bar and the negative electrode conductive bar. The second Y capacitor 15 includes capacitor CY2 and capacitor CY6. One end of capacitor CY2 is connected to the negative electrode conductive bar through a second connecting copper pillar 10, and the other end is connected to the first grounding device of the first mounting portion 4. One end of capacitor CY6 is connected to the positive electrode conductive bar through another second connecting copper pillar 10, and the other end is connected to the first grounding device of the first mounting portion 4. The first inductor element 1 includes inductor LCM1. Inductor LCM1 is respectively connected to the positive electrode conductive bar and the negative electrode conductive bar. The connection position of the first inductor element 1 and the conductive element 13 is located between the connection positions of the first capacitor element, the second capacitor element and the conductive element 13. The first capacitor element constitutes a first-stage filter. The first inductor element 1 and the second capacitor element constitute a second-stage filter. In this way, the first filter element has a high degree of integration, and the filter module has a good effect of eliminating noise signals.

[0083] Of course, in other examples, the first capacitor device may also include an X capacitor. The second capacitor device may also include only a Y capacitor or an X capacitor. The configuration of the first capacitor device and the second capacitor device is not limited to the above embodiment, and those skilled in the art may configure them according to actual needs.

[0084] In one example, the second filter device includes a third capacitor device, and the third capacitor device is suitable for being connected to the output terminal 9 of the filter module.

[0085] like Figures 2 to 4As shown, the third capacitor device is fixed to the second mounting portion 7. The second mounting portion 7 is provided with a second grounding device. The third capacitor device includes a third Y capacitor 16 and a second X capacitor. For example, the second X capacitor includes a capacitor CX2. The two ends of the capacitor CX2 are connected to the positive conductive bar and the negative conductive bar, respectively. The third Y capacitor 16 includes a capacitor CY3 and a capacitor CY4. One end of the capacitor CY3 is connected to the output end 9 of the negative conductive bar through a third connecting copper column 8, and the other end is connected to the second grounding device of the second mounting portion 7. One end of the capacitor CY4 is connected to the output end 9 of the positive conductive bar through another third connecting copper column 8, and the other end is connected to the second grounding device of the second mounting portion 7. The second inductor element 11 includes an inductor LCM2. The inductor LCM2 is connected to the positive conductive bar and the negative conductive bar, respectively. The connection position of the second inductor element 11 and the conductive element 13 is located between the connection positions of the second capacitor device, the third capacitor device and the conductive element 13. The first capacitor device constitutes a first-stage filter. The first inductor element 1 and the second capacitor device constitute a second-stage filter. The second inductor element 11 and the third capacitor element form a third-level filter. In this way, the filter module can eliminate noise signals more effectively.

[0086] Of course, the second capacitor device may also be provided with only a Y capacitor or an X capacitor. This application does not limit this, and those skilled in the art may configure it according to actual needs.

[0087] In one example, the first capacitive device and the second capacitive device both include a Y capacitor, the first mounting portion 4 is provided with a grounding device, and the Y capacitor of the first capacitive device and the Y capacitor of the second capacitive device are both connected to the grounding device.

[0088] As mentioned above, the first capacitive device includes a first Y capacitor 14. The second capacitive device includes a second Y capacitor 15. The grounding device is a first grounding device. Figure 2 , Figure 3 As shown, the first grounding device is a first grounding copper column 5. The first grounding copper column 5 is protruded upward from the first mounting portion 4. The first Y capacitor 14 and the second Y capacitor 15 are both connected to the first grounding copper column 5. In this example, the two Y capacitors are grounded through the same grounding device, which makes the structure of the first filter component simpler.

[0089] In an example, the Y capacitor of the second capacitive device includes a wiring element suitable for connecting to the conductive element 13 , and the wiring element is located between the first inductive element 1 and the second inductive element 11 .

[0090] As mentioned above, the Y capacitor of the second capacitive device is the second Y capacitor 15. Figure 2As shown, the second Y capacitor 15 is connected to the positive conductive bar and the negative conductive bar respectively through two second connecting copper pillars 10. The wiring element includes two second connecting copper pillars 10. The two second connecting copper pillars 10 are located between the first inductor element 1 and the second inductor element 11. In this way, the space between the first inductor element 1 and the second inductor element 11 can be fully utilized, so that the connection between the second Y capacitor 15 and the conductive element 13 becomes simple, and the space utilization rate of the filter module is further improved.

[0091] In one example, the first mounting portion 4 and the second mounting portion 7 both include a printed circuit board, and the printed circuit board is suitable for mounting the first filter component or the second filter component.

[0092] like Figure 2 , Figure 3 As shown, the first mounting portion 4 and the second mounting portion 7 both include printed circuit boards. The first Y capacitor 14, the second Y capacitor 15, and the first X capacitor 19 are electrically connected to components such as conductor elements, the first grounding copper pillar 5, and the first connecting copper pillar 3 through the wiring of the printed circuit board of the first mounting portion 4. The third Y capacitor 16 and the second X capacitor are electrically connected to components such as conductor elements, the second grounding copper pillar 6, and the third connecting copper pillar 8 through the wiring of the printed circuit board of the second mounting portion 7. In addition, the wiring of the printed circuit board can also play an electromagnetic shielding effect.

[0093] Of course, the structure and routing of the printed circuit board are not limited here, and those skilled in the art can configure them according to actual needs.

[0094] According to a third embodiment of the present application, a controller is provided, which includes a power distribution component and the filter module described in the present application, wherein the power distribution component is connected to an input end of the filter module.

[0095] The controller has the characteristics of high signal-to-noise ratio and compact structure.

[0096] In one example, the power distribution component includes a third filter component, one end of the third filter component is connected to the input end of the filter module, and the other end of the third filter component is connected to the output end of the power distribution component.

[0097] like Figure 4 , Figure 5As shown, the power distribution component is arranged in parallel with the conductive element 13. The power distribution component forms a power distribution branch. The power distribution component is used to supply power to external devices. Compared with the method of connecting the power distribution component to the output end of the filter module, that is, the output end 9 of the conductive element 13, in this example, when the noise signal is conducted inward, it must first be attenuated by the filter component and then conducted along the power distribution component. Due to the effect of the filter component, the noise signal has been attenuated, thereby greatly reducing the noise signal conducted along the power distribution component. In addition, the third filter component can further attenuate the noise signal, thereby solving the problem of noise coupling of the power distribution component during the wiring process, and further improving the filtering performance of the power distribution branch. In addition, the third filter component only includes the third inductor element 18 to meet the requirement of attenuating the noise signal. The third filter component has a simple structure and a small size.

[0098] In one example, the input end of the filter module is connected to the third filter component by a power distribution copper bus.

[0099] like Figure 5 As shown, one end of the distribution copper busbar 17 is connected to the input end 2 of the conductive element 13, and the other end is connected to the third filter component. For example, the third filter component includes a third inductor element 18. The third inductor element 18 is an inductor LCM3. The third inductor element 18 can play a filtering role. The conductive copper busbar 17 has a simple structure and high structural strength. This makes the connection between the third filter component and the input end of the filter module firm and highly reliable. In one example, the controller includes a conductive element 13, and the conductive element 13 includes an input end 2 and an output end 9, the first filter component is connected to the input end 2, and the second filter component is connected to the output end 9.

[0100] As mentioned above, Figure 2 , Figure 3 As shown, the conductive element 13 includes a positive conductive row and a negative conductive row. The first filter component includes a first Y capacitor 14. The first Y capacitor 14 is connected to the input terminal 2 of the positive conductive row and the negative conductive row through two first connecting copper pillars 3. The material of the positive conductive row and the negative conductive row is copper, aluminum, stainless steel, etc. The second filter component includes a third Y capacitor 16. The third Y capacitor 16 is connected to the output terminal 9 of the positive conductive row and the negative conductive row through two third connecting copper pillars 8. In this way, the electromagnetic interference of the external device connected to the output terminal 9 to the input terminal 2 can be effectively filtered out.

[0101] In an example, the conductive element 13 includes a first arm 131, a second arm 132 and a connecting arm 133, one end of the connecting arm 133 is connected to the first arm 131, and the other end of the connecting arm 133 is connected to the second arm 132, the first arm 131 and the second arm 132 are arranged opposite to each other, the first arm 131 has the input end 2, and the second arm 132 has the output end 9.

[0102] like Figure 2 , Figure 3 As shown, the conductive element 13 includes a positive conductive row and a negative conductive row. The two conductive rows are in the shape of a "J". The connecting arm 133 is located at the opening of the third accommodating cavity 123. The first arm 131 passes through the upper through hole 1231 of the third accommodating cavity 123 to reach the top of the first accommodating cavity 121. The two first connecting copper pillars 3 pass through the top wall of the first accommodating cavity 121 and are respectively connected to the input ends 2 of the two first arms 131. The second arm 132 passes through the lower through hole 1232 of the third accommodating cavity 123 to reach the top of the second accommodating cavity 122 and is located on one side of the first accommodating cavity 121. The two second connecting copper pillars 10 pass through the top wall of the second accommodating cavity 122 and are respectively connected to the output ends 9 of the two second arms 132. One end of the third connecting copper pillar 8 is connected to the second Y capacitor 15. The third connecting copper pillar 8 passes through the first accommodating cavity 121 and the third accommodating cavity 123, and the other end of the third connecting copper pillar 8 is connected to the middle of the connecting arm 133. The third connecting copper column 8 is located between the first inductor element 1 and the second inductor element 11 .

[0103] In this example, the structure of the conductive element 13 can adapt to the arrangement of the stacked first filter component and the second filter component, the first inductor element 1 and the second inductor element 11, so that the controller has high space utilization and compact structure.

[0104] Of course, the structure of the conductive element 13 is not limited to the above embodiment, and those skilled in the art can configure it according to actual needs.

[0105] In an example, the first filter component is located between the first arm 131 and the second arm 132 , and the second filter component is located on a side of the second arm 132 away from the first filter component.

[0106] like Figures 1 to 3 As shown, a spacing space is formed between the first arm 131 and the second arm 132. The first filter assembly is located between the first arm 131 and the second arm 132. The second arm 132 is located above the top wall of the second filter assembly and is located on one side of the first accommodating cavity 121. This arrangement makes full use of the space formed by the conductive element 13 of the cross-shaped structure, further improving the space utilization rate of the controller.

[0107] Of course, the arrangement positions of the first filter component and the second filter component are not limited to the above embodiments, and those skilled in the art can arrange them according to actual needs.

[0108] In one example, the first inductor element 1 is sleeved outside the first arm 131 , and the second inductor element 11 is sleeved outside the second arm 132 .

[0109] like Figure 2 , Figure 3 As shown, the first inductor element 1 and the second inductor element 11 are hollow structures. The first inductor element 1 is arranged around the upper through hole 1231. The second inductor element 11 is arranged around the lower through hole 1232. The first arm 131 passes through the upper through hole 1231. The second arm 132 passes through the lower through hole 1232. This arrangement makes full use of the middle space of the first inductor element 1 and the second inductor element 11, further improving the space utilization of the controller.
