[0039] To solve the above problems, the application provides an electric drive controller 2, which comprises a box body 10 and a sealing assembly 20. The box body 10 is formed with a containing space 11. The box body 10 comprises a wall part 12. The wall part 12 is provided with an operation hole 121 which is in communication with the containing space 11 and the outside. The wall part 12 comprises a flat part 122 and a folded part 123. The flat part 122 is used for separating the containing space 11 and the outside. The folded part 123 is folded away from the containing space 11 compared with the flat part 122. The folded part 123 is arranged around the operation hole 121. The sealing assembly 20 is arranged in the operation hole 121 and abuts against the inner side wall 1231 of the folded part 123. The sealing assembly 20 is used for plugging the operation hole 121.

[0040] The box 10 can be formed with a receiving space 11 to provide a suitable installation environment for components inside the receiving space 11, such as protection and support. The material of the box 10 can include but is not limited to metal alloys, such as aluminum alloys. The box 10 includes a wall portion 12, which can refer to any side wall of the box 10. For example, when the box 10 is square, the box 10 has six side walls, and the wall portion 12 can refer to any one or more of the six side walls. Optionally, the box 10 includes a coverable upper cover, and the wall portion 12 can be the upper cover. The material of the wall portion 12 can include but is not limited to composite steel plates. The wall portion 12 includes a flat portion 122 and a folded portion 123. The flat portion 122 can be used to define the boundary of the receiving space 11 to separate the receiving space 11 from the outside. The folded portion 123 is folded away from the side of the receiving space 11 compared to the flat portion 122. It should be noted that the folded portion 123 and the flat portion 122 can be an integral piece, and there is no gap at the connection between the folded portion 123 and the flat portion 122, thereby reducing the risk of gas leakage between the folded portion 123 and the flat portion 122. For example, during the manufacturing process, the folded portion 123 can be formed by outward folding of sheet metal. The wall portion 12 is provided with an operation hole 121 that communicates the receiving space 11 with the outside. The operation hole 121 can provide an operation channel for components inside the receiving space 11, and the shape of the operation hole 121 can include but is not limited to a circle. For example, an operator can perform operations such as fixing or disassembling components inside the receiving space 11 through the operation hole 121. The folded portion 123 surrounds the operation hole 121. It should be noted that the operation hole 121 can be formed by the flat portion 122 and the folded portion 123. In some embodiments, during the manufacturing process, part of the wall portion 12 is folded compared to the rest of the wall portion 12 to form the folded portion 123 and the flat portion 122, and the operation hole 121 is formed in the center of the folded portion 123 to penetrate the folded portion 123 and the flat portion 122. It should be noted that the depth of the operation hole 121 can be determined by the thickness of the flat portion 122 and the protrusion of the folded portion 123 compared to the flat portion 122. The sealing assembly 20 is arranged in the operation hole 121 and abuts the inner side wall 1231 of the folded portion 123, which can facilitate the sealing assembly 20 to block the operation hole 121 and alleviate the risk of gas leakage through the operation hole 121. It can be understood that when an operator needs to operate components inside the receiving space 11 through the operation hole 121, the sealing assembly 20 can be removed to expose the operation hole 121, and when the operator does not need to operate components inside the receiving space 11 through the operation hole 121, the sealing assembly 20 is arranged in the operation hole 121 and abuts the inner side wall 1231 of the folded portion 123 to block the operation hole 121.For example, compared with the mode that the sealing assembly 20 directly abuts against the flat portion 122 and surrounds the operation hole 121, the sealing assembly 20 of the present application abuts against the inner portion of the operation hole 121, so that the contact between the sealing assembly 20 and the wall portion 12 is more close, the sealing effect is improved, and the risk of air leakage between the sealing assembly 20 and the wall portion 12 is alleviated, and the structure is simple, and the installation stability of the sealing assembly 20 is better.

[0041] Through the above embodiment, the folded portion 123 is folded away from the containing space 11 and surrounds the operation hole 121, so that the sealing assembly 20 can abut against the inner side wall 1231 of the folded portion 123, so that the contact between the sealing assembly 20 and the wall portion 12 is more close, and the risk of air leakage between the sealing assembly 20 and the wall portion 12 is alleviated.

[0042] In some embodiments, the sealing assembly 20 includes a sealing plug 21 and a sealing ring 22, the sealing plug 21 is arranged in the operation hole 121 and is used to block the operation hole 121, the sealing ring 22 is arranged between the folded portion 123 and the sealing plug 21 and surrounds the operation hole 121, and the sealing plug 21 holds the sealing ring 22 on the inner side wall 1231 of the folded portion 123. The sealing plug 21 can include but is not limited to a screw plug and the like. The sealing plug 21 can be arranged in the operation hole 121 and block the operation hole 121, thereby sealing the operation hole 121. The sealing ring 22 can be annular, and the sealing ring 22 can be made of plastic or rubber and the like. The sealing ring 22 can cooperate with the sealing plug 21 to seal the operation hole 121, the sealing plug 21 holds the sealing ring 22 on the inner side wall 1231 of the folded portion 123, so as to facilitate the sealing ring 22 to seal between the sealing plug 21 and the inner side wall 1231, and alleviate the risk of air leakage between the sealing plug 21 and the inner side wall 1231.

[0043] In some embodiments, the radial dimension of the portion of the operation hole 121 corresponding to the folded portion 123 gradually increases in the direction away from the containing space 11, so as to facilitate the sealing ring 22 to be fully compressed by the sealing plug 21 in the depth direction of the operation hole 121 under the guidance of the inner side wall 1231 of the folded portion 123, improve the sealing effect, and further alleviate the risk of air leakage between the sealing ring 22 and the inner side wall 1231 of the folded portion 123.

[0044] In some embodiments, the wall portion 12 has a first wall surface 124 and a second wall surface 125 arranged oppositely, the first wall surface 124 is farther away from the accommodating space 11 than the second wall surface 125 at the flat portion 122, the folding portion 123 has a third wall surface 126 connecting the first wall surface 124 and the second wall surface 125, the second wall surface 125 extends to the folding portion 123 and forms an inner side wall 1231, and the sealing plug 21 holds the sealing ring 22 against the second wall surface 125. The first wall surface 124 can be an outer wall surface of the wall portion 12, and the second wall surface 125 can be an inner wall surface of the wall portion 12. It can be understood that, at the flat portion 122, the first wall surface 124 is farther away from the accommodating space 11 than the second wall surface 125, and at the folding portion 123, the first wall surface 124 is farther away from the operation hole 121 than the second wall surface 125, i.e., the folding portion 123 is formed by folding outwardly toward the first wall surface 124, and part of the second wall surface 125 and the entire third wall surface 126 are exposed to the outside, so that the second wall surface 125 forms the inner side wall 1231 of the folding portion 123. It should be noted that the sealing plug 21 holds the sealing ring 22 against the second wall surface 125, and the third wall surface 126 is located on a side away from the accommodating space 11 relative to the sealing ring 22. The gas does not need to contact the third wall surface 126 on the airtight channel, thereby relieving the risk of gas leakage through the third wall surface 126, and when the electric drive controller 2 is subjected to airtight inspection, the airtightness of the third wall surface 126 does not need to be checked specially, thereby improving the detection efficiency and saving the cost.

[0045] In some embodiments, the wall portion 12 comprises, in the direction from the first wall surface 124 to the second wall surface 125, a first metal layer 127, a damping layer 128 and a second metal layer 129 which are sequentially stacked, the first metal layer 127 is used to form the first wall surface 124, the second metal layer 129 is used to form the second wall surface 125, and at least part of the damping layer 128 is exposed to the outside through the third wall surface 126. For example, the material of the wall portion 12 can be a composite steel plate, the first metal layer 127 and the second metal layer 129 can be galvanized steel plates, and the damping layer 128 can be a high-molecular damping material. The first metal layer 127, the damping layer 128 and the second metal layer 129 are sequentially stacked, so as to achieve the effect of suppressing vibration and reducing noise, thereby improving the noise, vibration and harshness (NVH) performance of the electric drive controller 2. It can be understood that, when the operation hole 121 is formed, the third wall surface 126 is a cut section of the wall portion 12, and the damping layer 128 is exposed through the third wall surface 126. Due to the material properties of the damping layer 128, gas is easy to enter the damping layer 128 through the third wall surface 126 and leak to the outside of the accommodation space 11. Therefore, the third wall surface 126 is directly exposed to the outside through the folding portion 123, and the airflow passage between the exposed damping layer 128 of the third wall surface 126 and the accommodation space 11 is blocked by the sealing assembly 20, which greatly reduces the risk of gas leakage caused by the leakage of the damping layer 128, and improves the efficiency of the airtightness detection.

[0046] In some embodiments, the electric drive controller 2 further comprises a mounting assembly 30, the mounting assembly 30 comprises a mounting seat 31 installed in the accommodation space 11, and the mounting seat 31 is provided with a fixing hole 311 in communication with the operation hole 121. The sealing plug 21 extends into the accommodation space 11 through the operation hole 121 and is inserted into the fixing hole 311. The mounting assembly 30 can be used to provide fixation and support for the components in the accommodation space 11. The sealing plug 21 extends into the accommodation space 11 through the operation hole 121 and is connected with the mounting seat 31 through the fixing hole 311, which can facilitate the sealing plug 21 to block the operation hole 121, improve the installation stability of the sealing plug 21, and reduce the risk of the sealing plug 21 falling off and exposing the operation hole 121, and facilitate the sealing plug 21 to fully compress the sealing ring 22.

[0047] In some embodiments, the sealing plug 21 is provided with a first thread 211, the inner wall of the fixing hole 311 is provided with a second thread 312, and the sealing plug 21 is inserted into the fixing hole 311 through the first thread 211 and the second thread 312. In this embodiment, the first thread 211 is an external thread, the second thread 312 is an internal thread, and the sealing plug 21 and the mounting seat 31 are connected by screwing. Compared with clamping and inserting, screwing is more stable and easier to install and adjust the sealing plug 21. The sealing plug 21 can be a hexagonal socket, and the sealing plug 21 can be a standard part, thereby further reducing the cost.

[0048] In some embodiments, the sealing plug 21 includes a cap 212 and a connecting column 213 connected to the cap 212. The connecting column 213 is connected to the mounting seat 31 through the operation hole 121 and the fixing hole 311, and the cap 212 is located outside the box body 10 and abuts against the box body 10 to cover the operation hole 121. The connecting column 213 is connected to the mounting seat 31 through the operation hole 121, so that the cap 212 can abut against the box body 10 to cover the operation hole 121, thereby reducing the influence of water vapor and dust in the external environment on the components in the accommodation space 11 and their work. The end face of the cap 212 away from the connecting column 213 can be provided with a hole for rotating the sealing plug 21, which can be matched with other tools to disassemble and assemble the sealing plug 21. The first thread 211 can be provided on the outer wall of the connecting column 213.

[0049] In some embodiments, the electric drive controller 2 further includes a busbar 40, and the box body 10 is further provided with a mounting hole 13. The busbar 40 is partially inserted into the accommodation space 11 through the mounting hole 13. The mounting hole 13 can provide a channel for the busbar 40 to be partially inserted into the accommodation space 11. The busbar 40 can be a high-voltage busbar. In some embodiments, the busbar 40 can be a high-voltage busbar 40. The busbar 40 includes a plug-in part which is partially inserted into the accommodation space 11 through the mounting hole 13 to be connected to the mounting assembly 30. For example, the plug-in part is installed in the accommodation space 11 through the mounting hole 13 by a bolt, and the bolt can be placed into the accommodation space 11 through the operation hole 121. It can be understood that the operator can fix the plug-in part of the busbar 40 which is partially inserted into the accommodation space 11 through the operation hole 121. When the busbar 40 is fixed through the operation hole 121, the accommodation space 11 can only communicate with the outside through the operation hole 121, thereby reducing the area of the busbar 40 exposed outside the accommodation space 11 and improving the safety factor of the electric drive controller 2.

[0050] In some embodiments, the mounting seat 31 is provided with a guide groove 313 for guiding the busbar 40 to be inserted into the accommodation space 11 to be connected with the mounting assembly 30. The mounting seat 31 can be an injection molding part, and the guide groove 313 can be directed towards the opening direction of the mounting hole 13 or other directions, for guiding the busbar 40 which can be inserted into the guide groove 313 or pass through the guide groove 313 to be partially inserted into the accommodation space 11. In this way, the guide groove 313 can guide the busbar 40, reducing the risk of the locking bolt of the busbar 40 being stuck due to the inclination of the busbar 40 in the accommodation space 11, thereby facilitating the installation and disassembly of the busbar 40.

[0051] In summary, the electric drive controller 2 provided by the application includes a box body 10 and a sealing assembly 20. The box body 10 is formed with an accommodation space 11. The box body 10 includes a wall portion 12 provided with an operation hole 121 communicating the accommodation space 11 with the outside. The wall portion 12 includes a flat portion 122 for separating the accommodation space 11 from the outside and a folded portion 123 folded away from the accommodation space 11 compared with the flat portion 122. The folded portion 123 is arranged around the operation hole 121. The sealing assembly 20 is arranged through the operation hole 121 and abuts against the inner side wall 1231 of the folded portion 123. The sealing assembly 20 is used to block the operation hole 121. According to the above embodiments, the folded portion 123 is folded away from the accommodation space 11 compared with the flat portion 122 and arranged around the operation hole 121, so that the sealing assembly 20 can abut against the inner side wall 1231 of the folded portion 123, making the contact between the sealing assembly 20 and the wall portion 12 more close, thereby relieving the risk of air leakage between the sealing assembly 20 and the wall portion 12. Compared with other electric drive controllers, the electric drive control sealing effect provided by the application is better, and the structure is simple and the cost is low.
