[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Referring to Figures 1, 3, and 4, an embodiment of this application provides an inductor module 10. The inductor module 10 includes a housing 11, an inductor body 12, and a first circuit board 13. The housing 11 has a receiving cavity 111, and the inductor body 12 is disposed within the receiving cavity 111. The first circuit board 13 has a conductive support 132 and an electrical connection portion 131. The inductor body 12 has electrodes 121, which are electrically connected to the electrical connection portion 131. The electrical connection portion 131 is electrically connected to the conductive support 132 through an internal circuit. The conductive support 132 is used for electrical connection to an external circuit. For example, the conductive support 132 is used for electrical connection to the circuit board of an inverter.

[0044] Optionally, electrode 121 is enameled wire. Of course, in other embodiments, electrode 121 may also be bare wire, and is not limited thereto.

[0045] It should be noted that, referring to Figure 3, the inductor body 12 includes inductor cells 122, which can be one, two, or more than three. In this embodiment, there are four inductor cells 122, which are arranged side by side in the accommodating cavity 111.

[0046] During installation, the electrodes 121 of the inductor body 12 are electrically connected to the electrical connection portion 131 of the first circuit board 13. The electrical connection portion 131 is electrically connected to the conductive bracket 132 through an internal circuit. In this way, the inductor module 10 can be electrically connected to an external circuit through the conductive bracket 132. Thus, during the assembly of the inductor module 10, no cables are required, avoiding the risk of cables being punctured during assembly, packaging, and transportation. Furthermore, the assembly process eliminates the need for straightening, bending, or securing cables, improving production efficiency. In addition, it reduces the space occupied by cables, resulting in a compact structure.

[0047] In one embodiment, referring to FIG3, the housing 11 further includes an opening 112 communicating with the receiving cavity 111. The inductor module 10 also includes a mounting bracket 14, which includes a mounting body 141 and a support leg 142. The mounting body 141 covers the opening 112, and the support leg 142 is located on the side of the mounting body 141 facing the receiving cavity 111 and is disposed within the receiving cavity 111. The first circuit board 13 is mounted on the side of the mounting body 141 opposite to the support leg 142. The mounting body 141 has a through hole 1411 through which the electrode 121 passes and is electrically connected to the electrical connection portion 131. A mounting bracket 14 is provided at the opening 112. On the one hand, the mounting bracket 14 is equivalent to a cover, making the accommodating cavity 111 a sealed space. This can prevent external substances from entering the accommodating cavity 111 and causing damage to the inductor body 12, thus extending the service life of the inductor module 10. On the other hand, the mounting bracket 14 provides a mounting base for the first circuit board 13, making it convenient to install the first circuit board 13.

[0048] It should be noted that the number of support legs 142 can be set according to actual needs, and no specific limitation is made here. Optionally, there are six support legs 142, which are arranged in two rows and three columns to better support the mounting body 141.

[0049] In one embodiment, referring to Figures 2, 3, and 6, the mounting body 141 has a placement groove 1413 on the side facing the housing 11, and the placement groove 1413 communicates with the receiving cavity 111. During installation, the upper part of the inductor body 12 is received within the placement groove 1413, the top of the inductor body 12 is in contact with the bottom of the placement groove 1413, and there is a safety distance between the bottom of the inductor body 12 and the housing 11. Thus, by providing the placement groove 1413, the receiving groove plays a positioning role for the inductor body 12, ensuring that the inductor body 12 is placed in a designated position and that there is a safety distance between the bottom of the inductor body 12 and the housing 11.

[0050] It should be noted that, referring to Figure 6, the number of placement slots 1413 is equal to the number of inductor cells 122. In this embodiment, there are four placement slots 1413 and four inductor cells 122, and the four placement slots 1413 are arranged side by side and interconnected.

[0051] In one embodiment, referring to FIG. 6, a through hole 1411 is located at the bottom of the placement groove 1413. Referring to FIG. 2, the through hole 1411 is a tapered hole, and the cross-sectional area of ​​the tapered hole gradually decreases from the housing 11 to the first circuit board 13. Optionally, the cross-sectional shape of the tapered hole is flat, such as a strip hole. During installation, the electrode 121 passes through the hole 1411 from the side of the mounting bracket 14 facing the housing 11 to the side of the mounting bracket 14 facing the first circuit board 13. Since the through hole 1411 is a tapered hole, the tapered hole acts as a guide, which facilitates the electrode 121 passing through the mounting bracket 14. After the electrode 121 passes through the hole 1411 to the side of the mounting bracket 14 facing the first circuit board 13, the tapered hole can also effectively position the electrode 121, which facilitates the wiring of the adapter board.

[0052] In one embodiment, referring to Figures 1 and 3, the first circuit board 13 is detachably mounted on the mounting bracket 14. Specifically, the first circuit board 13 is detachably mounted on the side of the mounting body 141 opposite to the support leg 142. In this way, the first circuit board 13 can be removed from the mounting bracket 14, facilitating inspection and maintenance of the first circuit board 13.

[0053] Optionally, referring to Figure 4, the first circuit board 13 is provided with a first fixing hole 1323. Referring to Figures 2 and 4, the mounting body 141 is provided with a stud 1412, the stud 1412 is provided with a second fixing hole 14121, and a fastener 15 is provided in the first fixing hole 1323 and the second fixing hole 14121. The fastener 15 is a screw or the like. This allows the first circuit board 13 and the mounting bracket 14 to be detachable.

[0054] Of course, in other embodiments, the first circuit board 13 may also be snapped onto the mounting bracket 14, and this is not a limitation.

[0055] In one embodiment, referring to Figures 1 and 3, the mounting bracket 14 is detachably mounted to one end of the housing 11 having an opening 112. This allows the mounting bracket 14 to be removed from the housing 11, facilitating inspection and maintenance of the inductor body 12 within the accommodating cavity 111.

[0056] Optionally, referring to Figures 3 and 5, the mounting bracket 14 is provided with a first mounting hole 1415, and the housing 11 is provided with a second mounting hole 114. Mounting components 16 are provided within the first mounting hole 1415 and the second mounting hole 114. The mounting components 16 are screws or the like. This allows for a detachable connection between the mounting bracket 14 and the housing 11.

[0057] In one embodiment, referring to Figures 3 and 5, the side wall of the housing 11 is provided with a first limiting portion, and the side of the mounting bracket 14 is provided with a second limiting portion. The first limiting portion and the second limiting portion are mutually limitingly engaged. During installation, the mounting bracket 14 is placed at the opening 112 of the housing 11. First, the first limiting portion and the second limiting portion are mutually limitingly engaged, and then the mounting component 16 is used to fix the mounting bracket 14 to the housing 11. In this way, the method of positioning first and then fixing can improve the installation accuracy and precision of the mounting component 16, and also helps to improve installation efficiency.

[0058] Optionally, referring to Figures 2 and 4, the first limiting part includes a limiting protrusion, and the second limiting part has a limiting groove. Alternatively, the first limiting part has a limiting groove, and the second limiting part includes a limiting protrusion. During installation, the mounting bracket 14 is placed at the opening 112, with the limiting protrusion corresponding to the limiting groove. Then, an external force is applied to the mounting bracket 14, causing it to move towards the housing 11, and the limiting protrusion slides into the limiting groove. Thus, the use of a limiting protrusion and a limiting groove for limiting engagement facilitates positioning and improves positioning efficiency.

[0059] It should be noted that the number of the first and second limiting parts can be set according to actual needs, and is not specifically limited here. In this embodiment, referring to Figures 2 and 4, there are four first and four second limiting parts. Two of the first limiting parts are respectively provided on one side wall of the housing 11, and the other two are respectively provided on the other side wall of the housing 11. Two of the second limiting parts are spaced apart on one side of the mounting bracket 14, and the other two are spaced apart on the other side of the mounting bracket 14.

[0060] In one embodiment, referring to Figures 3 and 5, the mounting bracket 14 is provided with a glue-filling hole 1414, which communicates with the receiving cavity 111. During installation, after the mounting bracket 14 is fixed to the end of the housing 11 with the opening 112, glue is poured into the receiving cavity 111 through the glue-filling hole 1414. The glue cures to form a colloid 17 to serve as an insulating seal.

[0061] Further, referring to Figure 3, the potting hole 1414 is offset from the inductor body 12. Optionally, the potting hole 1414 is located at the edge of the mounting bracket 14. Because the potting hole 1414 is offset from the inductor body 12, this prevents glue from flowing from the potting hole 1414 onto the electrodes 121 of the inductor body 12, ensuring that the inductor body 12 can operate normally.

[0062] Furthermore, referring to Figure 5, at least two glue-filling holes 1414 are provided, and all glue-filling holes 1414 are respectively located on opposite sides of the mounting bracket 14. In use, glue can be poured into the receiving cavity 111 simultaneously through the glue-filling holes 1414. This can avoid the glue from being too concentrated, which would affect the glue-filling efficiency and quality, and improve the glue-filling efficiency and quality.

[0063] In this embodiment, referring to Figure 4, there are four glue-filling holes 1414, two of which are spaced apart on one side of the mounting bracket 14, and the other two are spaced apart on the other side of the mounting bracket 14.

[0064] In one embodiment, referring to Figures 3 and 6, the mounting bracket 14 is further provided with a vent 1416, which communicates with the receiving cavity 111. Optionally, the vent 1416 is located at the bottom of the placement groove 1413. During glue filling, the gas in the receiving cavity 111 can be discharged through the vent 1416 so that the receiving cavity 111 can be filled with glue.

[0065] It should be noted that, referring to Figure 6, the number of vent holes 1416 can be set according to actual needs, and is not specifically limited here. In this embodiment, the number of vent holes 1416 is equal to the number of inductor cells 122, and there are four vent holes 1416.

[0066] In one embodiment, referring to FIG. 3, the inductor module 10 further includes a seal 18, which is disposed at one end of the housing 11 having an opening 112. By providing the seal 18, the inductor module 10 can be sealed and mounted on the inverter support plate 30.

[0067] Optionally, the housing 11 has a mounting groove at one end with an opening 112. The seal 18 is a sealing ring adapted to the opening 112, and a portion of the sealing ring is disposed within the mounting groove.

[0068] In one embodiment, referring to FIG4, the electrical connection portion 131 is provided with a solder hole 1313, and the end of the electrode 121 facing away from the inductor body 12 is disposed in the solder hole 1313 and soldered to the wall of the solder hole 1313. Alternatively, the electrical connection portion 131 includes a solder pad, and the end of the electrode 121 facing away from the inductor body 12 is soldered to the solder pad. In this way, the electrode 121 is connected to the electrical connection portion 131 by soldering, and the connection between the electrode 121 and the electrical connection portion 131 is firm and reliable.

[0069] It should be noted that there are multiple ways to solder the electrode 121 to the electrical connection part 131. Optionally, the electrode 121 and the electrical connection part 131 can be soldered together. In this way, only local heating of the connection part is required, which will not have a thermal impact on the first circuit board 13. At the same time, the heating and cooling speeds are fast, and the connection reliability is high.

[0070] This application also provides an inverter, including the inductor module 10 of any of the above embodiments.

[0071] In the inverter described above, during installation, the electrodes 121 of the inductor body 12 are electrically connected to the electrical connection portion 131 of the first circuit board 13. The electrical connection portion 131 is electrically connected to the conductive bracket 132 through an internal circuit. This allows the inductor module 10 to be electrically connected to an external circuit via the conductive bracket 132. Consequently, no cables are required during the assembly of the inductor module 10, avoiding the risk of cables being punctured during assembly, packaging, and transportation. Furthermore, the assembly process eliminates the need for straightening, bending, or securing cables, improving production efficiency. In addition, it reduces the space occupied by cables, resulting in a more compact structure.

[0072] In one embodiment, referring to Figures 7, 8, and 9, the inverter further includes a support plate 30, a second circuit board 21, and a third circuit board 22. The first circuit board 13 is electrically connected to the second circuit board 21 and the third circuit board 22, and the second circuit board 21 is electrically connected to the third circuit board 22.

[0073] Since the inductor module 10 generates heat during use, it is placed on one side of the support plate 30, while the second circuit board 21 and the third circuit board 22 are placed on the other side of the support plate 30. This avoids damage to the circuit board 20 caused by the heat generated by the inductor module 10.

[0074] In one embodiment, referring to FIG3, the inductor body 12 includes at least one inductor unit 122, and the inductor unit 122 is provided with two electrodes 121, namely a first electrode 1211 and a second electrode 1212. At least two electrical connection portions 131 are provided, namely a first electrical connection portion 1311 and a second electrical connection portion 1312. At least two conductive supports 132 are provided, namely a first conductive support 1321 and a second conductive support 1322.

[0075] Furthermore, the first electrode 1211 is electrically connected to the first electrical connection portion 1311, the first electrical connection portion 1311 is electrically connected to the first conductive support 1321, and the first conductive support 1321 is electrically connected to the second circuit board 21. The second electrode 1212 is electrically connected to the second electrical connection portion 1312, the second electrical connection portion 1312 is electrically connected to the second conductive support 1322, and the second conductive support 1322 is electrically connected to the third circuit board 22. In this way, the inductor module 10, the second circuit board 21, and the third circuit board 22 are electrically connected to form a circuit.

[0076] Optionally, the first electrode 1211 and the second electrode 1212 are of equal length, so that the inductor body 12 can be composed of multiple inductor units 122 of the same type, avoiding the risk of misplacing the inductor units 122.

[0077] In one embodiment, referring to Figures 7 and 9, the support plate 30 is provided with a clearance hole 31, and the first circuit board 13 is disposed in the clearance hole 31. The second circuit board 21 is disposed on the side of the first circuit board 13. It should be noted that there is a certain safety gap between the second circuit board 21 and the first circuit board 13, and the second circuit board 21 is flush with the first circuit board 13. The third circuit board 22 is disposed on the side of the first circuit board 13 and the second circuit board 21 away from the support plate 30, and one end of the third circuit board 22 is disposed opposite to the first circuit board 13, and the other end of the third circuit board 22 is disposed opposite to the second circuit board 21. In this way, by reasonably setting the positions of the first circuit board 13, the second circuit board 21 and the third circuit board 22, the electrical connection between the first circuit board 13, the second circuit board 21 and the third circuit board 22 is facilitated.

[0078] Further, referring to Figures 7 and 9, the second circuit board 21 has a third conductive bracket 211 and a fourth conductive bracket 212 on the side facing the third circuit board 22. The third conductive bracket 211 is electrically connected to the first conductive bracket 1321, the second conductive bracket 1322 is electrically connected to the third circuit board 22, and the fourth conductive bracket 212 is electrically connected to the third circuit board 22. In this embodiment, the first conductive bracket 1321 and the third conductive bracket 211 have the same height, and the second conductive bracket 1322 and the fourth conductive bracket 212 have the same height.

[0079] In one embodiment, the first conductive bracket 1321 is provided with a first connection hole 13211, and the second conductive bracket 1322 is provided with a second connection hole 2111.
