When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The term "vertical" and similar expressions used in this specification are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0050] Unless otherwise specified, the term "multiple" in this application refers to two or more.

[0051] This application provides an integrated inverter component, including a tray, a control board, a control drive board, an expansion box, and a PG card. A flat mounting structure is adopted, with each component mounted on the tray. The control board and control drive board are integrated and fixed to the tray with screws. Optional components, such as adapter boards, expansion boxes, and PG cards, are detachable for easy customer selection.

[0052] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Please see Figure 1 and Figure 2 , Figure 1 A perspective view of the inverter integrated component 100 according to an embodiment of this application is shown. Figure 2 A perspective view of the tray 10 is shown. The frequency converter integrated component 100 includes the tray 10, control board 20, control drive board 30, and adapter board 40. The tray 10 serves as the main support for the components.

[0054] In some embodiments, the tray 10 surrounds an installation space, and the control board 20, the control drive board 30, and the adapter board 40 are all installed within the installation space.

[0055] In some embodiments, the tray 10 includes a first mounting area 101 and a second mounting area 102 arranged along a first direction x. A control board 20 is mounted in the first mounting area 101, and a control drive board 30 is mounted in the second mounting area 102. The control board 20 and the control drive board 30 are electrically connected. Along a second direction z, a portion of an adapter plate 40 is located between the tray 10 and the control board 20. The control board 20 is electrically connected to the adapter plate 40 to facilitate the installation of an extension piece on the adapter plate 40 to achieve electrical connection between the extension piece and the control board 20. The first direction x and the second direction z are perpendicular to each other.

[0056] In some embodiments, the tray 10 is generally cuboid. For ease of description, in the embodiments of this application, the width direction of the tray 10 is taken as the first direction x, the height direction of the tray 10 is taken as the second direction z, and the length direction of the tray 10 is taken as the third direction y, wherein the first direction x, the second direction z, and the third direction y are all perpendicular to each other.

[0057] In some embodiments, such as Figure 2 and Figure 3 As shown, the tray 10 includes a spacer 110, which divides the installation space into a first installation area 101 and a second installation area 102. The spacer 110 serves two purposes: firstly, it enhances the aesthetics of the space, allowing users to easily distinguish between different areas; secondly, it acts as a reinforcing rib to increase the stability of the tray 10.

[0058] In some embodiments, the spacer 110 may be omitted.

[0059] In some embodiments, a plurality of first reinforcing ribs 120 are provided in the first mounting area 101, and a plurality of second reinforcing ribs 130 are provided in the second mounting area 102 to enhance the stability of the tray 10.

[0060] It is understandable that multiple first reinforcing ribs are arranged in an alternating pattern, and multiple second reinforcing ribs are arranged in an alternating pattern.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, a first limiting member 140a is provided in the first installation area 101. The first limiting member 140a extends from the tray 10 towards the control plate 20, that is, the first limiting member 140a extends along the second direction z towards the control plate 20. The first limiting member 140a is used to limit the control plate 20 to achieve the initial positioning of the control plate 20. For example, there are multiple first limiting members 140a. Some of the multiple first limiting members 140a are arranged along the first direction x to restrict the movement of the control plate 20 along the first direction x, and the remaining parts of the multiple first limiting members 140a are arranged along the third direction y to restrict the movement of the control plate 20 along the third direction y.

[0062] In the embodiments of this application, such as Figure 2 and Figure 4 As shown, the control panel 20 is generally rectangular in shape, and there are two first limiting members 140a. The two first limiting members 140a are arranged at intervals along the first direction x to limit one side of the control panel 20. Furthermore, a stop part 150 is also provided in the first mounting area 101, which is used to limit the other side of the control panel 20.

[0063] In some embodiments, the first limiting member 140a is integrally formed with the tray 10.

[0064] In some embodiments, the stop portion 150 is integrally formed with the tray 10.

[0065] In some embodiments, a first positioning post 160a is provided in the first installation area 110. The first positioning post 160a extends from the tray 10 toward the control plate 20. That is, the first positioning post 160a extends along the second direction z toward the direction away from the tray 10. The control plate 20 is fixed to the first positioning post 160a.

[0066] In some embodiments, there are three first positioning posts 160a, which are distributed in a triangular pattern on the tray 10.

[0067] In this embodiment, the number of first positioning posts 160a is three, and the three first positioning posts 160a are arranged in a triangle on the tray 10. Specifically, please refer to... Figure 5 The first positioning post 160a has a first positioning hole 161a, and the control plate 20 has a second positioning hole 210 at a position corresponding to the first positioning hole 161a. The first fastener 90a passes through the second positioning hole 210 and the first positioning hole 161a in sequence to fix the control plate 20 to the first positioning post 160a. The first fastener 90a can be a screw.

[0068] In other embodiments, there are four first positioning posts 160a, which are arranged in a rectangular shape on the tray 10.

[0069] In some embodiments, such as Figure 2 and Figure 10 As shown, the first limiting member 140a is provided with a first step portion 141a, and the control plate 20 is engaged in the first step portion 141a and abuts against the first positioning post 160a, so that the control plate 20 and the tray 10 are spaced apart by a certain space, which is conducive to the installation of the adapter plate 40 and at the same time helps to realize the connection between the control plate 20 and the adapter plate 40.

[0070] It is understandable that the height of the first step 141a is equal to the height of the first positioning post 160a.

[0071] In some embodiments, the first positioning post 160a is integrally formed with the tray 10.

[0072] In some embodiments, such as Figure 2 and Figure 6 As shown, a second positioning post 160b is provided in the second installation area 102. The second positioning post 160b extends from the tray 10 toward the control drive board 30. That is, the second positioning post 160b extends along the second direction z toward the direction away from the tray 10. The control drive board 30 is fixed to the second positioning post 160b.

[0073] In some embodiments, there are three second positioning posts 160b, which are arranged in a triangular pattern on the tray.

[0074] In this embodiment, the number of second positioning posts 160b is four, and the four second positioning posts 160b are arranged in a rectangular distribution on the tray 10. Specifically, please refer to... Figure 5 and Figure 6 The second positioning post 160b is provided with a third positioning hole 161b, and the control drive board 30 is provided with a fourth positioning hole 310 corresponding to the third positioning hole 161b. The second fastener 90b passes through the fourth positioning hole 310 and the third positioning hole 161b in sequence to fix the control drive board 30 to the second positioning post 160b. The second fastener 90b can be a screw.

[0075] In some embodiments, the second positioning post 160b is integrally formed with the tray.

[0076] In some embodiments, along the second direction z, the height of the first positioning post 160a is higher than the height of the second positioning post 160b, which is beneficial for the subsequent insertion of the PG card 60 into the control drive board 30, thereby reducing the overall height of the inverter integrated component 100 and reducing the volume of the tray component.

[0077] In some embodiments, the electrical connection between the control board 20 and the control drive board 30 includes, but is not limited to, communication via a 14-pin ribbon cable.

[0078] In some embodiments, such as Figure 2 As shown, a first support member 170a is provided in the first installation area 101. The first support member 170a is used to support the control board 20 when the wire is plugged in.

[0079] In some embodiments, the first support member 170a may be omitted, and both the first limiting member 140a and the first positioning post 160a can support the control plate 20.

[0080] In some embodiments, a second support member 170b is provided in the second installation area 102, and the second support member 170b is used to support the control drive board 30 when the wire is plugged in.

[0081] In some embodiments, the second support member 170b may be omitted, and the second positioning post 160b may support the drive control board 30.

[0082] In some embodiments, a first wiring hole 180a is provided in the first mounting area 101. The first wiring hole 180a penetrates the tray 10 and extends along the second direction z. The projection of the first wiring hole 180a is located within the projection of the control board 20, which helps to shorten the length of the wire and save costs. A second wiring hole 180b is provided in the second mounting area 102. The second wiring hole 180b penetrates the tray 10 and extends along the second direction z. The projection of the second wiring hole 180b is located within the projection of the control drive board 30, which also helps to shorten the length of the wire and save costs. The first wiring hole 180a is used for the user to select whether the control board 20 is grounded, and the second wiring hole 180b is used for the user to select whether the control drive board 30 is grounded.

[0083] In some embodiments, a second limiting member 140b is provided in the first mounting area 110. The second limiting member 140b extends from the tray 10 toward the control plate 20, that is, the second limiting member 140b extends along the second direction z toward the control plate 20. The second limiting member 140b is used to limit the adapter plate 40 to achieve the initial positioning of the adapter plate 40. The provision of the second limiting member 140b is beneficial to the installation of the adapter plate 40.

[0084] For example, there are multiple second limiting members 140b, some of which are arranged along the first direction x to restrict the transition plate 40 from moving along the first direction x, and the remaining parts of the multiple second limiting members 140b are arranged along the third direction y to restrict the transition plate 40 from moving along the third direction y.

[0085] In some embodiments, such as Figure 5 As shown, the adapter plate 40 is L-shaped. The adapter plate 40 includes a first plate 410 and a second plate 420 that are connected to each other. The first plate 410 extends in a third direction y, and the second plate 420 extends in a first direction x. Along the second direction Z, a portion of the first plate 410 is located between the tray 10 and the control plate 20.

[0086] In some embodiments, the number of second limiting members 140b is at least 4, wherein two second limiting members 140b are arranged at intervals along a first direction x to restrict the first plate 410 from moving along the first direction x, and the other two second limiting members 140b are arranged at intervals along a third direction y to restrict the second plate 420 from moving along the third direction y.

[0087] In the embodiments of this application, such as Figure 7 and Figure 8As shown, there are 6 second limiting members 140b. Two second limiting members 140b are arranged at intervals along the first direction x to restrict the movement of the first plate 410 along the first direction x. Two second limiting members 140b are arranged at intervals along the third direction y to restrict the movement of the second plate 420 along the third direction y. One of the remaining two second limiting members 140b is located at the end of the first plate 410 away from the second plate 420, and the other is located at the end of the second plate 420 away from the first plate 410 to limit the end of the adapter plate 40.

[0088] In some embodiments, a plurality of second limiting members 140b together enclose a first slot (not shown in the figure), and an adapter plate 40 is disposed in the first slot.

[0089] In some embodiments, the second limiting member 140b is provided with a second step portion 141b (e.g., Figure 10 As shown), the adapter plate 40 is mounted on the second step 141b to create a certain space between the adapter plate 20 and the tray 10, so as to facilitate the installation of terminals on the adapter plate 40 and avoid interference between the terminal pins and the bottom of the tray 10.

[0090] It is understandable that the aforementioned second step portion 141b together encloses and forms the first groove.

[0091] In some embodiments, the second limiting member 140b is integrally formed with the tray 10.

[0092] In some embodiments, the height of the first step portion 141a (or the first positioning post 160a) is higher than the height of the second step portion 141b in the direction extending from the tray 10 to the control board 20, so that the adapter plate 40 and the control board 20 can be connected by terminals.

[0093] In some embodiments, the adapter plate 40 is detachably mounted on the tray 10. A first locking member 190a is provided in the first mounting area 101. The first locking member 190a is used to fix the adapter plate 40 to the tray 10, which facilitates further fixing of the adapter plate 40 to achieve the connection between the adapter plate 40 and the tray 10.

[0094] In some embodiments, the first locking element 190a is a snap-fit.

[0095] In some embodiments, the first locking member 190a is integrally formed with the tray 10.

[0096] It is understood that the first locking member 190a avoids the aforementioned first limiting member 140a, first positioning post 160a and second limiting member 140b.

[0097] In some embodiments, the adapter plate 40 is provided with a first terminal 70a, and the control plate 20 is plugged into the first terminal 70a. Specifically, the first terminal 70a is provided on the first plate 410.

[0098] In some embodiments, such as Figure 2 and Figure 11 As shown, the tray 10 has a notch 80a, in which the first terminal 70a is exposed, so that it can be observed through the notch 80a whether the control board 20 is connected to the first terminal 70a.

[0099] It is understandable that the notch 80a is located at the edge of the tray 10.

[0100] In some embodiments, the inverter integrated component 100 includes an optional expansion box 50. For ease of installation of the expansion box 50, such as... Figure 2 and Figure 9 As shown, a third limiting member 140c is provided in the first installation area 101. The third limiting member 140c extends from the tray 10 toward the expansion box 50, that is, the third limiting member 140c extends toward the expansion box 50 along a third direction z. The third limiting member 140c is used to restrict the movement of the expansion box 50. For example, there are multiple third limiting members 140c. Some of the multiple third limiting members 140c are arranged along the first direction x to restrict the movement of the expansion box 50 along the first direction x, and the remaining parts of the multiple third limiting members 140c are arranged along a third direction y to restrict the movement of the expansion box 50 along the third direction y.

[0101] In this embodiment, the expansion box 50 is generally rectangular, and there are four third limiting members 140c, which are located at the four corners of the expansion box 50. The four third limiting members 140c enclose a second slot (not shown in the figure), and the expansion box 50 is disposed in the second slot. Preferably, each of the third limiting members 140c is provided with a third step portion 141c (e.g., ...). Figure 10 As shown, the expansion box 50 is mounted on the third step 141c so that there is a certain space between the expansion box 50 and the tray 10, which is conducive to the connection between the expansion box 50 and the adapter plate 40.

[0102] It is understandable that the aforementioned third step portion 141c together encloses and forms the second groove.

[0103] In some embodiments, the height of the third step portion 141c is higher than the height of the second step portion 141b in the direction extending from the tray 10 to the control plate 20, which is beneficial for connecting the expansion box 50 and the adapter plate 40.

[0104] In some embodiments, the expansion box 50 is detachably connected to the tray 10, which helps to improve assembly efficiency and reduce costs. Specifically, a second locking member 190b is provided in the first mounting area 110. The second locking member 190b is used to fix the expansion box 50 to the tray 10, which helps to further fix the expansion box 50 to achieve the connection between the expansion box 50 and the tray 10.

[0105] In some embodiments, the second locking member 190b is a snap-fit. At least two second locking members 190b are provided within the first mounting area 110. Specifically, the at least two second locking members 190b are spaced apart along a first direction x, and are used to secure the expansion box 50 to the tray 10; or the at least two second locking members 190b are spaced apart along a third direction y, and are used to secure the expansion box 50 to the tray 10; or one of the at least two second locking members 190b is used to lock a first side of the expansion box 50, and the other of the at least two first locking members 190b is used to lock a second side of the expansion box 50, with the first and second sides adjacent to each other.

[0106] In some embodiments, the second locking member 190b is a slot. The expansion box 50 is provided with a hook that matches the slot. Preferably, there are two slots, with two slots spaced apart along a first direction x on the tray 10, or two slots arranged along a third direction y on the tray 10.

[0107] In this embodiment, the number of expansion boxes 50 is two. The two expansion boxes 50 are arranged side by side along the first direction x in the first mounting area 101. That is, the second board 420 is provided with two second terminals 70b, and the two expansion boxes 50 are respectively plugged into one of the second terminals 70b.

[0108] In some embodiments, such as Figure 8 and Figure 9 As shown, the adapter board 40 is provided with a second terminal 70b, and the expansion box 50 is plugged into the second terminal 70b. Specifically, the second terminal 70b is located on the second board 420.

[0109] In some embodiments, such as Figure 5 As shown, the adapter plate 40 is L-shaped. The adapter plate 40 includes a first plate 410 and a second plate 420 connected to each other, with a second terminal 70b disposed on the second plate 420. The first plate 410 extends in a third direction y, and the second plate 420 extends in a first direction x. Along a second direction z, a portion of the first plate 410 is located between the tray 10 and the control plate 20, and the second plate 420 is disposed between the tray 10 and the expansion box 50, facilitating the insertion of the second terminal 70b into the expansion box 50. In some embodiments, please refer to... Figure 5The adapter board 40 is configured in an L-shape, with the first terminal 70a located on the first board 410 and the second terminal 70b located on the second board 420. This arrangement of the first terminal 70a and the second terminal 70b in an orthogonal configuration can achieve physical foolproofing and prevent the control board 20 from being mistakenly inserted into the expansion box 50.

[0110] The adapter board 40 isolates electrical interference between the control board 20 and the expansion box 50. For example, some expansion boxes 50 may introduce electromagnetic interference; the adapter board 40 can shield and suppress this interference to a certain extent, protecting the normal operation of the control board 20 and avoiding the risk of control board 20 failure due to direct connection. In addition, the adapter board 40 reduces the risk of loosening or damage to the control board 20 interface caused by repeated plugging and unplugging of the expansion box 50, making the connection between the control board 20 and the expansion box 50 more stable.

[0111] In some embodiments, such as Figure 1 As shown, the inverter integrated component 100 also includes an optional PG card 60, which, together with the control drive board 30, is arranged in the second mounting area 102 along the third direction y.

[0112] In some embodiments, such as Figure 2 As shown, a fourth limiting member 140d is provided in the second installation area 102. The fourth limiting member 140d extends away from the tray 10 along the second direction z, that is, it extends towards the PG card 60 along the second direction z. The fourth limiting member 140d is used to limit the PG card 60 to achieve the initial positioning of the PG card 60. For example, there are two fourth limiting members 140d, which are arranged at intervals along the first direction x, or at intervals along the third direction y.

[0113] In the embodiments of this application, such as Figure 1 and Figure 7 As shown, the PG card 60 is roughly rectangular in shape, with three fourth limiting members 140d arranged in a triangle on the tray 10. Parts of the fourth limiting members 140d pass through the PG card 60 to achieve initial positioning of the PG card 60. Specifically, a fifth positioning hole 610 (e.g., ...) is provided on the PG card 60 at a position corresponding to the fourth limiting member 140d. Figure 5 As shown), part of the fourth limiting member 140d passes through the fifth positioning hole 610 to achieve the initial positioning of the PG card 60.

[0114] In some embodiments, the fourth limiting member 140d is provided with a fourth step portion 141d (e.g., Figure 7As shown), the PG card 60 is engaged in the fourth step portion 141d through the fifth positioning hole 610. That is, in the direction extending from the tray 10 to the PG card 60, the part of the fourth limiting member 140d located above the fourth step portion 141d passes through the PG card 60, so that the PG card 60 is separated from the tray 10 by a certain space, which facilitates the connection between the PG card 60 and the control drive board 30.

[0115] In some embodiments, the height of the fourth step portion 141d is higher than the height of the second positioning post 160b in the direction extending from the tray 10 toward the PG card 60.

[0116] In some embodiments, the fourth limiting member 140d is integrally formed with the tray 10.

[0117] In some embodiments, the PG card 60 is detachably mounted on the tray 10. This is to further secure the PG card 60, thus establishing a connection between the PG card 60 and the tray 10. Figure 5 and Figure 6 As shown, a third locking member 190c is provided in the first installation area 101. The first locking member 190c is used to fix the PG card 60 to the tray 10.

[0118] In some embodiments, the third locking element 190c is a snap-fit.

[0119] In some embodiments, the third locking member 190c is integrally formed with the tray 10.

[0120] In some embodiments, the control driver board 30 is electrically connected to the PG card 60 via a third terminal 70c. For example, the control driver board 30 is connected to the third terminal 70c, and the PG card 60 is inserted into the third terminal 70c, thereby realizing the connection between the control driver board 30 and the PG card 60.

[0121] In some embodiments, such as Figure 6 As shown, a third support 170c is provided in the second installation area 102. The third support 170c is used to support the PG card 60 when it is plugged in.

[0122] It is understood that, along the direction extending from the tray 10 to the control board 20, the height of the third support member 170c is higher than the height of the second support member 170b, so as to facilitate the insertion of the PG card 60 into the third terminal 70c on the control drive board 30.

[0123] It should be noted that the third support component 170c can be omitted, and the third positioning post 160c can support the PG card.

[0124] In some embodiments, such as Figure 1As shown, the inverter integrated component 100 also includes a first cable outlet 80b, which is used for the wires of the terminals on the control board 20 to pass through, for example, by tying cable ties at the first cable outlet 80b. Preferably, the first cable outlet 80b is located between two expansion boxes 50, which on the one hand uses the gap between the two expansion boxes 50 to limit the wires, which is conducive to neatness and avoids wire tangling, and on the other hand makes reasonable use of space.

[0125] In some embodiments, the first outlet 80b is formed on the tray 10.

[0126] In some embodiments, the inverter integrated component 100 further includes a second outlet 80c for wires from the terminals on the control drive board 30 to pass through, for example, by tying a cable tie at the second outlet 80c.

[0127] In some embodiments, the second outlet 80c is formed on the tray 10.

[0128] It should be noted that both the first cable outlet 80b and the second cable outlet 80c are located on the edge of the tray 10.

[0129] This application also provides a frequency converter for high power applications, including the frequency converter integrated component 100 described above.

[0130] In some embodiments, the frequency converter is a high-power frequency converter. Here, high power means a power of 90kW or more.

[0131] This application provides an integrated inverter component and inverter. By laying the control board and control drive board separately in a first mounting area and a second mounting area, respectively, the integration of the control board and control drive board onto a single board is avoided, reducing costs. Furthermore, an adapter plate is provided between the tray and the control board, making the tray structure clearly defined and improving space utilization. It also reduces the risk of being unable to connect multiple devices due to different or insufficient control board interfaces, allowing the control board to adapt to various specifications of expansion devices.
