The large number of parts leads to complex assembly. Summary of the Invention

[0004] The main objective of this invention is to propose an integrated module that aims to improve the problem of complex assembly caused by the large number of parts.

[0005] To achieve the above objectives, the present invention proposes an integrated module comprising:

[0006] Filtering module;

[0007] A bus capacitor module is integrated with the filter module. The input terminal of the bus capacitor module is connected to the output terminal of the filter module, and the filter module is positioned close to the core of the bus capacitor module.

[0017] In one embodiment of the present invention, potting compound is provided in the first mounting groove.

[0018] In one embodiment of the present invention, a cooling channel is formed between the power module and the wall of the second mounting slot.

[0019] In one embodiment of the present invention, a sealant is provided between the edge of the power module and the edge of the second mounting groove, the sealant being used to seal the cooling channel.

[0043] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0047] This invention proposes an integrated module designed to improve the problem of complex assembly caused by the large number of parts.

[0048] The specific structure of the integrated module of the present invention will be described below:

[0049] See also Figures 1 to 3In one embodiment of the integrated module of the present invention, the integrated module includes a filter module 20 and a bus capacitor module 30; the bus capacitor module 30 is integrated with the filter module 20, the input terminal of the bus capacitor module 30 is connected to the output terminal of the filter module 20, and the filter module 20 is disposed close to the core package of the bus capacitor module 30.

[0050] It is understood that in the integrated module proposed in this invention, by integrating the filter module 20 and the bus capacitor module 30 together, it can be installed in the motor controller in the form of a module, instead of installing them in the motor controller as separate components. This can effectively improve the problem of complex assembly caused by the large number of components.

[0051] In addition, by connecting the input terminal of the bus capacitor module 30 to the output terminal of the filter module 20, and by placing the filter module 20 close to the core package of the bus capacitor module 30, the core package 33 of the bus capacitor module 30 can act as the X capacitor of the filter module 20. This eliminates the need for the design of the X capacitor of the filter module 20, resulting in a smaller overall size and lower cost for the inverter module 100.

[0052] Furthermore, by presenting the integrated module as a module within the motor controller, this solution can greatly improve the versatility and applicability of the integrated module. It can also mitigate the problems of high cost, large size, heavy weight, and high failure rate caused by installing the modules sequentially as individual components within the motor controller.

[0053] In this embodiment, the input terminal of the filter module 20 can be used to connect to an external power supply to input DC power to the filter module 20.

[0054] In practical applications, the output terminal of the filter module 20 and the input terminal of the bus capacitor module 30 can be connected by welding, screw connection or other methods to achieve electrical connection between the filter module 20 and the bus capacitor module 30.

[0055] In practical applications, the filter module 20 can be set on one side of the bus capacitor module 30, or it can be set above or below the bus capacitor module 30.

[0056] Furthermore, in conjunction with reference Figures 6 to 9 In one embodiment of the integrated module of the present invention, a mounting space 30a is provided on one side of the bus capacitor module 30, and the filter module 20 is located in the mounting space 30a.

[0057] By placing the filter module 20 within the mounting space 30a of the bus capacitor module 30, the integration between the filter module 20 and the bus capacitor module 30 can be improved, resulting in a smaller overall volume occupied by the filter module 20 and the bus capacitor module 30, which in turn can further reduce the overall volume of the integrated module.

[0058] Furthermore, in conjunction with reference Figures 6 to 9 In one embodiment of the integrated module of the present invention, the bus capacitor module 30 is provided with a plurality of spaced core packages 33, the plurality of core packages 33 enclosing an installation space 30a, and the filter module 20 is disposed close to at least one core package 33.

[0059] This configuration, by enclosing multiple core packages 33 to form an installation space 30a and placing the filter module 20 close to the core packages 33, allows the core package 33 closest to the filter module 20 to function as both the X capacitor of the filter module 20 and the core package 33 of the bus capacitor module 30. This achieves the requirement of one core package 33 fulfilling two functions, eliminating the need for the design of the X capacitor of the filter module 20, resulting in a smaller overall size of the inverter module 100. It also reduces the distance between this core package 33 and the Y core package 33 of the filter module 20, leading to better filtering performance of the filter module 20.

[0060] In some embodiments, the filter module 20 may include a common-mode inductor 21, a positive conductive rod 22a, a negative conductive rod 22b, a first through-hole Y capacitor 23a, a second through-hole Y capacitor 23b, a filter positive conductive element 24a, a filter negative conductive element 24b, and a ground conductive element 25. The positive conductive rod 22a and the negative conductive rod 22b are connected together through the common-mode inductor 21, and then through the first feedthrough Y capacitor 23a and the second feedthrough Y capacitor 23b, respectively. The grounding conductive element 25 spatially wraps part of the common-mode inductor 21 to isolate the internal electromagnetic field of the grounding conductive element 25. One pole of the first feedthrough Y capacitor 23a is connected to the grounding conductive element 25, and the other pole is connected to the filter positive conductive element 24a. One pole of the second feedthrough Y capacitor 23b is connected to the grounding conductive element 25, and the other pole is connected to the filter negative conductive element 24b. The filter positive conductive element 24a and the filter negative conductive element 24b are connected to the positive conductive rod 22a and the negative conductive rod 22b, respectively. In this way, the filter module 20 can effectively filter out the interference signals generated by the inverter module 100 and conducted along the high-voltage bus during operation, thereby improving the EMC (Electromagnetic Compatibility) performance of the motor controller.

[0061] It should be noted that the end of the positive conductive rod 22a away from the positive conductive component 24a and the end of the negative conductive rod 22b away from the negative conductive component 24b are the input terminals of the filter module 20; the positive conductive component 24a and the negative conductive component 24b are the output terminals of the filter module 20.

[0062] In some embodiments, the filter module 20 has a rear side and two adjacent sides, with the rear side being the end where the output terminal of the filter module 20 is located. At least one core package 33 is correspondingly disposed on the rear side of the filter module 20, and at least one core package 33 is correspondingly disposed on each of the two adjacent sides of the filter module 20. The multiple core packages 33 enclose and form an installation space 30a. This allows the bus capacitor module 30 to have sufficient capacitance while effectively reducing the overall width of the filter module 20 and the bus capacitor module 30. Simultaneously, it allows the filter module 20 to be closer to the core packages 33 of the bus capacitor module 30, thereby enabling the filter module 20 to achieve a better filtering effect.

[0063] Furthermore, in conjunction with reference Figure 8 , Figure 9 In one embodiment of the integrated module of the present invention, an insulating member 32 is provided between the positive conductor 31a and the negative conductor 31b of the bus capacitor module 30 at the input end.

[0064] With this configuration, by providing an insulating element 32 between the positive conductor 31a and the negative conductor 31b of the busbar, the positive conductor 31a and the negative conductor 31b of the busbar can be insulated to prevent short circuits caused by conduction between them.

[0065] For example, the insulating element 32 can be a plastic part.

[0066] In some embodiments, the busbar positive conductor 31a may include a first conductive portion and a second conductive portion arranged at an angle, and the busbar negative conductor 31b may include a third conductive portion and a fourth conductive portion arranged at an angle. The first conductive portion and the third conductive portion are arranged opposite to each other, and the core package 33 is sandwiched between the first conductive portion and the third conductive portion, and the insulating member 32 is sandwiched between the second conductive portion and the fourth conductive portion. In this way, the first conductive portion and the third conductive portion can be connected to the filter positive conductor 24a and the filter negative conductor 24b respectively, and the second conductive portion and the fourth conductive portion can be connected to the input copper busbar of the power module 40, which can better realize the connection between each output terminal and the input terminal.

[0067] See also Figures 1 to 9The present invention also proposes an inverter module 100, which includes a bracket 10, a power module 40, and an integrated module as described above. The specific structure of the integrated module is as described in the above embodiments. Since the inverter module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The bracket 10 is provided with a first mounting slot 111 and a second mounting slot 112; the filter module 20 is integrated in the first mounting slot 111; the bus capacitor module 30 is integrated in the first mounting slot 111, and the input end of the bus capacitor module 30 is connected to the output end of the filter module 20; the power module 40 is integrated in the second mounting slot 112, and the input end of the power module 40 is connected to the output end of the bus capacitor module 30.

[0069] It is understood that in the inverter module 100 proposed in this invention, the filter module 20 and the bus capacitor module 30 are both integrated into the first mounting slot 111 of the bracket 10, and the power module 40 is integrated into the second mounting slot 112 of the bracket 10, so that the filter module 20, the bus capacitor module 30 and the power module 40 are all integrated on one bracket 10 to form an inverter module 100. In this way, it can be installed in the motor controller in the form of a module, instead of being installed in the motor controller in the form of individual components, thereby effectively improving the problem of complex assembly caused by a large number of components.

[0070] In addition, by integrating both the filter module 20 and the bus capacitor module 30 into the first mounting slot 111 of the bracket 10, the core package 33 of the bus capacitor module 30 can serve as the X capacitor of the filter module 20. This eliminates the need for the design of the X capacitor in the filter module 20, resulting in a smaller overall size and lower cost for the inverter module 100.

[0071] Furthermore, by presenting the inverter module 100 in the form of a module within the motor controller, this solution can greatly improve the versatility and applicability of the inverter module 100. It can also improve the problems of high cost, large size, heavy weight, and high failure rate caused by installing the modules sequentially as individual components within the motor controller.

[0072] In practical applications, the output terminal of the bus capacitor module 30 and the input terminal of the power module 40 can also be connected by welding, screw connection or other methods to achieve electrical connection between the bus capacitor module 30 and the power module 40.

[0073] Furthermore, in conjunction with reference Figure 2 , Figure 3In one embodiment of the inverter module 100 of the present invention, the bus capacitor module 30 is located between the filter module 20 and the power module 40.

[0074] This configuration, by placing the bus capacitor module 30 between the filter module 20 and the power module 40, allows the output terminal of the filter module 20 and the input terminal of the bus capacitor module 30 to be close to each other. This enables the output terminal of the filter module 20 to be directly connected to the input terminal of the bus capacitor module 30 without the need for additional connecting cables, thus reducing costs and improving assembly efficiency. Furthermore, this configuration also allows the output terminal of the bus capacitor module 30 to be close to the input terminal of the power module 40, enabling direct connection without additional connecting cables, further reducing costs and improving assembly efficiency.

[0075] Furthermore, in conjunction with reference Figures 6 to 9 In one embodiment of the inverter module 100 of the present invention, the bus capacitor module 30 is provided with an installation space 30a on the side away from the power module 40, and the filter module 20 is located in the installation space 30a.

[0076] By placing the filter module 20 within the installation space 30a of the bus capacitor module 30, the integration between the filter module 20 and the bus capacitor module 30 can be improved, resulting in a smaller overall volume occupied by the filter module 20 and the bus capacitor module 30, which in turn can further reduce the overall volume of the inverter module 100.

[0077] Furthermore, in conjunction with reference Figure 2 , Figure 3 In one embodiment of the inverter module 100 of the present invention, a potting compound 1111 is provided in the first mounting groove 111.

[0078] With this configuration, during the assembly process, the filter module 20 and the bus capacitor module 30 can be installed into the first mounting slot 111 of the bracket 10, and then potting compound 1111 can be poured into the first mounting slot 111. This allows the filter module 20 and the bus capacitor module 30 to be potted simultaneously, integrating the potting process. Compared with separate potting methods, this solution saves on equipment investment and manufacturing costs.

[0079] For example, the material of potting compound 1111 can be epoxy resin.

[0080] Furthermore, in conjunction with reference Figure 2 , Figure 3 In one embodiment of the inverter module 100 of the present invention, a cooling channel 14 is formed between the power module 40 and the wall of the second mounting slot 112.

[0081] With this configuration, during assembly, after the power module 40 is installed into the second mounting slot 112 of the bracket 10, a cooling channel 14 can be formed between the power module 40 and the wall of the second mounting slot 112. Coolant can be introduced into the cooling channel 14, so that the heat generated by the power module 40 during operation can be quickly removed by the flow of coolant, thereby improving the output capability of the power module 40. At the same time, it also has a heat dissipation effect on the bus capacitor module 30 and the filter module 20.

[0082] In practical applications, the power module 40 can form a cooling channel 14 by enclosing the bottom wall of the second mounting slot 112, or by enclosing the side wall of the second mounting slot 112, or by enclosing both the bottom wall and the side wall of the second mounting slot 112.

[0083] Furthermore, in conjunction with reference Figure 2 , Figure 5 In one embodiment of the inverter module 100 of the present invention, a sealant 15 is provided between the edge of the power module 40 and the edge of the groove of the second mounting groove 112, and the sealant 15 is used to seal the cooling channel 14.

[0084] With this configuration, by providing sealant 15 between the edge of the power module 40 and the edge of the slot of the second mounting groove 112, the cooling channel 14 can be sealed with sealant 15 to prevent leakage of the cooling channel 14.

[0085] In addition, potting compound 1111 and sealant 15 can be baked and cured simultaneously. Compared with the method of baking and curing separately, this solution saves equipment investment, energy consumption and manufacturing costs, while also improving assembly efficiency.

[0086] Furthermore, in conjunction with reference Figures 3 to 5 In one embodiment of the inverter module 100 of the present invention, the edge of the second mounting groove 112 is provided with an annular groove 1121, and the sealant 15 is at least partially disposed in the annular groove 1121.

[0087] This configuration allows for the application of sealant 15 into the annular groove 1121, which improves the problem of sealant 15 dripping before curing. After the sealant 15 has cured, most of the sealant 15 will be located within the annular groove 1121, thereby enhancing the sealing effect of the sealant 15 on the cooling channel 14.

[0088] For example, the material of sealant 15 can be a solvent-free two-component silane-based special polymer high-resilience sealant. Furthermore, sealant 15 can be formed using the CIPG process, which involves applying a liquid sealant to the flange surface, curing it by heat, and then assembling it, achieving a very good sealing effect.

[0089] Furthermore, in conjunction with reference Figure 2 , Figure 5 In one embodiment of the inverter module 100 of the present invention, the bracket 10 includes a frame 11, a current sensor core 12, and a three-phase output copper busbar 13; the frame 11 is provided with a first mounting groove 111 and a second mounting groove 112; the current sensor core 12 is integrated into the frame 11, and there are three current sensor cores 12; each phase copper busbar of the three-phase output copper busbar 13 passes through a current sensor core 12, and the three-phase output copper busbar 13 is connected to the three-phase output terminal of the power module 40.

[0090] With this configuration, during the injection molding process, the current sensor core 12 and the three-phase output copper busbar 13 can be directly embedded into the frame 11, making the current sensor core 12 and the three-phase output copper busbar 13 part of the bracket 10, thus increasing the integration of the bracket 10 and consequently increasing the integration of the inverter module 100.

[0091] In practical applications, the three-phase output copper busbar 13 and the three-phase output terminal of the power module 40 can be connected by welding, screw connection or other methods to achieve the connection between the three-phase output copper busbar 13 and the power module 40.

[0092] In practical applications, the frame 11 can be made of plastic. Of course, the frame 11 can also be made of metal. When the frame 11 is made of metal, the current sensor core 12 and the three-phase output copper busbar 13 can be injection molded into a single part and then assembled onto the frame 11 to achieve the same function as the integrated plastic bracket 10. Furthermore, when using a metal frame 11, the better thermal conductivity of metal results in better heat dissipation for the bus capacitor module 30 and the filter module 20.

[0093] Furthermore, in conjunction with reference Figure 2 , Figure 5 In one embodiment of the inverter module 100 of the present invention, the current sensor core 12 and the three-phase output copper busbar 13 are both located on one side of the three-phase output terminal of the power module 40.

[0094] This configuration allows the current sensor core 12 and the three-phase output copper busbar 13 to be close to the three-phase output terminal of the power module 40, so that the three-phase output copper busbar 13 can be directly connected to the three-phase output terminal of the power module 40 without the need for additional connecting wires. This not only reduces costs but also improves assembly efficiency.

[0095] Furthermore, in conjunction with reference Figures 1 to 3In one embodiment of the inverter module 100 of the present invention, the inverter module 100 further includes a circuit board 50, which covers the slot of the first mounting slot 111 and the slot of the second mounting slot 112, and the signal pins of the power module 40 are electrically connected to the circuit board 50.

[0096] With this configuration, by covering the slot opening of the first mounting slot 111 and the slot opening of the second mounting slot 112 with the circuit board 50, the circuit board 50 can also be integrated on the bracket 10 to further improve the integration of the inverter module 100. In addition, the circuit board 50 can also limit and fix the filter module 20, the bus capacitor module 30 and the power module 40 to improve the installation stability of the filter module 20, the bus capacitor module 30 and the power module 40.

[0097] In practical applications, the signal pins of the power module 40 can be connected to the circuit board 50 by means of soldering, screw connection, etc., to realize the electrical connection between the signal pins of the power module 40 and the circuit board 50.

[0098] In practical applications, the circuit board 50 can be fixed to the bracket 10 by screws or rivets to improve the installation reliability of the circuit board 50.

[0099] The present invention also proposes a motor controller, which includes the inverter module 100 as described above. The specific structure of the inverter module 100 is as described in the above embodiments. Since the present motor controller adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0100] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
