[0041] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.
[0042] like Figure 1 and Figure 2 As shown, the electric control cover plate 10 of the embodiment of the present disclosure includes a cover plate body 1 and a plurality of connecting edges 2, and the plurality of connecting edges 2 are arranged around the cover plate body 1. The connecting edge 2 is provided with a first connecting hole 21 in the middle of its length direction, and the inner surface of the cover plate body 1 is provided with a first reinforcement area 11 at the first connection hole 21, and a reinforcement rib is provided in the first reinforcement area 11.
[0043] The electric control cover plate 10 of the embodiment of the present disclosure can effectively improve the stiffness and natural mode of the first connection hole 21 of the electric control cover plate 10 by setting a first reinforcement area 11 on the inner surface of the cover plate body 1 and setting reinforcement ribs in the first reinforcement area 11, thereby improving the stiffness and natural mode of the electric control cover plate 10, thereby improving the modal performance of the electric control cover plate 10 and reducing the radiation noise of the motor controller.
[0044] In some embodiments, Figure 1 and Figure 2 As shown, the multiple reinforcing ribs provided in the first reinforcing area 11 are first reinforcing ribs 111. The first reinforcing ribs 111 are in the shape of long strips. The extension direction of the first reinforcing ribs 111 intersects with the extension direction of the corresponding connecting edge 2. In other words, the angle between the extension direction of the first reinforcing ribs 111 and the extension direction of the corresponding connecting edge 2 is greater than 0° and less than 180°. The multiple first reinforcing ribs 111 in the same first reinforcing area 11 are parallel to each other.
[0045] The connection edge 2 corresponding to the first reinforcing rib 111 can be understood as: the connection edge 2 closest to the first reinforcing rib 111. The extension direction of the first reinforcing rib 111 intersects with the extension direction of the corresponding connection edge 2.
[0046] For example, Figure 1 and Figure 2 As shown, the electric control cover plate 10 is rectangular and has four connecting edges 2, two of which extend along the length direction of the electric control cover plate 10 and are arranged on opposite sides of the cover plate body 1 along the width direction of the electric control cover plate 10; the other two connecting edges 2 extend along the width direction of the electric control cover plate 10 and are arranged on opposite sides of the cover plate body 1 along the length direction of the electric control cover plate 10.
[0047] The connecting side 2 extending along the length direction of the electric control cover plate 10 is the short side, and the connecting side 2 extending along the width direction of the electric control cover plate 10 is the long side. The first reinforcing rib 111 provided at the first connecting hole 21 of the long side is parallel to the extending direction of the short side, and the first reinforcing rib 111 provided at the first connecting hole 21 of the short side is parallel to the extending direction of the long side. Figure 1 , Figure 2 and Figure 4 As shown in the X direction, the length direction of the electric control cover plate 10 is as shown in Figure 1 , Figure 2 and Figure 4 As shown in the Y direction.
[0048] By setting the extension direction of the first reinforcing rib 111 to intersect with the extension direction of the corresponding connecting edge 2, and setting the multiple first reinforcing ribs 111 arranged in the same first reinforcing area 11 to be parallel to each other, it is not only beneficial to further improve the stiffness and natural mode of the electric control cover plate 10 and reduce the radiation noise of the motor controller; it also facilitates the processing and manufacturing of the multiple first reinforcing ribs 111 in the same first reinforcing area 11, thereby facilitating the processing and manufacturing of the electric control cover plate 10, which is beneficial to reducing the cost of the electric control cover plate 10.
[0049] Optionally, the extension direction of the first reinforcing rib 111 is perpendicular to the extension direction of the corresponding connecting edge 2 .
[0050] For example, the extending direction of the first reinforcing rib 111 disposed at the short side is perpendicular to the extending direction of the short side, and the extending direction of the first reinforcing rib 111 disposed at the long side is perpendicular to the extending direction of the long side.
[0051] By setting the extension direction of the first reinforcing rib 111 to be perpendicular to the extension direction of the corresponding connecting edge 2, it is beneficial to further improve the stiffness and natural mode of the electric control cover plate 10 and reduce the radiation noise of the motor controller.
[0052] Alternatively, if Figure 1 and Figure 2 As shown, among at least two adjacent first reinforcing ribs 111 , the length of the first reinforcing rib 111 close to the first connecting hole 21 is greater than the length of the first reinforcing rib 111 away from the first connecting hole 21 .
[0053] For example, Figure 1 As shown, among two adjacent first reinforcing ribs 111 extending along the X direction and located on the same side of the first connecting hole 21 in the Y direction, the closer they are to the first connecting hole 21 in the Y direction, the longer they are, and the farther they are from the first connecting hole 21 in the Y direction, the shorter they are.
[0054] It should be noted that the overall setting trend of the first reinforcing rib 111 is: among at least two adjacent first reinforcing ribs 111, the length of the first reinforcing rib 111 close to the first connection hole 21 is greater than the length of the first reinforcing rib 111 far from the first connection hole 21. However, due to the setting of other structures on the cover body 1, the length of the first reinforcing rib 111 close to the first connection hole 21 of some of the two adjacent first reinforcing ribs 111 is less than the length of the first reinforcing rib 111 far from the first connection hole 21. For example, a depression is provided at the first connection hole 21, and one end of the first reinforcing rib 111 can only extend to the edge of the depression, resulting in the length of the first reinforcing rib 111 facing the first connection hole 21 being less than the length of the first reinforcing rib 111 far from the first connection hole 21.
[0055] It is understandable that the rigidity of the first connection hole 21 of the electric control cover plate 10 is relatively poor. If you want to effectively improve the overall rigidity of the electric control cover plate 10, you need to focus on improving the rigidity of the first connection hole 21. The closer the first reinforcing rib 111 is to the first connection hole 21, the more effectively the rigidity of the first connection hole 21 can be improved. By setting the length of the first reinforcing rib 111 close to the first connection hole 21 to be longer, the rigidity of the first connection hole 21 can be effectively improved, and at the same time, by setting the length of the first reinforcing rib 111 far from the first connection hole 21 to be shorter, the weight and cost of the electric control cover plate 10 can be effectively reduced. Therefore, when the rigidity of the electric control cover plate 10 is good, the electric control cover plate 10 can also be lightweight.
[0056] Alternatively, if Figure 1 As shown, the distance between two adjacent first reinforcing ribs 111 at the short side is 6 mm to 8 mm.
[0057] For example, Figure 1 As shown, the distance between two adjacent first reinforcing ribs 111 at the short side is L1, and L1 is 7.5 mm.
[0058] Alternatively, if Figure 1 and Figure 2 As shown, among at least three adjacent first reinforcing ribs 111 , the distance between two adjacent first reinforcing ribs 111 close to the first connection hole 21 is smaller than the distance between two adjacent first reinforcing ribs 111 away from the first connection hole 21 .
[0059] For example, Figure 1As shown, among the first reinforcing ribs 111 extending along the Y direction, the closer the distance between two adjacent first reinforcing ribs 111 is to the first connection hole 21 in the X direction, the smaller the distance between two adjacent first reinforcing ribs 111 is to the first connection hole 21 in the X direction; the farther the distance between two adjacent first reinforcing ribs 111 is from the first connection hole 21 in the X direction, the larger the distance between them.
[0060] It is understandable that the rigidity of the first connection hole 21 of the electric control cover plate 10 is poor. If you want to effectively improve the overall rigidity of the electric control cover plate 10, you need to focus on improving the rigidity of the first connection hole 21. The closer the first reinforcing rib 111 is to the first connection hole 21, the more effectively the rigidity of the first connection hole 21 can be improved. By setting the spacing between two adjacent first reinforcing ribs 111 close to the first connection hole 21 to be smaller, the rigidity of the first connection hole 21 can be effectively improved. At the same time, by setting the spacing between two adjacent first reinforcing ribs 111 far from the first connection hole 21 to be larger, the weight and cost of the electric control cover plate 10 can be effectively reduced. Therefore, when the rigidity of the electric control cover plate 10 is good, the lightweight of the electric control cover plate 10 can also be achieved.
[0061] Optionally, the distance between two adjacent first reinforcing ribs 111 close to the first connection hole 21 is 6 mm to 8 mm, and the distance between two adjacent first reinforcing ribs 111 away from the first connection hole 21 is 12 mm to 16 mm.
[0062] For example, the distance between two adjacent first reinforcing ribs 111 close to the first connection hole 21 is L2, L2 is 7 mm, and the distance between two adjacent first reinforcing ribs 111 far from the first connection hole 21 is L3, 3 is 14 mm.
[0063] Alternatively, if Figure 2 As shown, the cover body 1 includes a plate body 101 and an annular frame 102. The annular frame 102 is arranged around the plate body 101. The plate body 101 and the connecting edge 2 are arranged on opposite sides of the annular frame 102 in the thickness direction of the cover body 1. The first reinforcing rib 111 is arranged on the plate body 101, and one end of the first reinforcing rib 111 close to the corresponding connecting edge 2 extends to the annular frame 102. The thickness direction of the cover body 1 is as shown in FIG. Figure 1 , Figure 2 and Figure 4 The Z direction is consistent.
[0064] For example, one end of the first reinforcing rib 111 disposed at the short side close to the short side extends to the annular frame 102 ; and one end of the first reinforcing rib 111 disposed at the long side close to the long side extends to the annular frame 102 .
[0065] By extending one end of the first reinforcing rib 111 close to the corresponding connecting edge 2 to the annular frame 102, the first reinforcing rib 111 can be more effectively utilized to improve the stiffness at the first connecting hole 21, which is beneficial to further improve the stiffness and natural mode of the electric control cover plate 10 and reduce the radiation noise of the motor controller.
[0066] In some embodiments, Figure 1 and Figure 2 As shown, at least one reinforcing rib provided in the first reinforcement area 11 is a connecting rib, and each first reinforcing rib 111 is connected to the connecting rib, so that all the first reinforcing ribs 111 are connected through the connecting rib.
[0067] By arranging connecting ribs in the first reinforcement area 11 and connecting all the first reinforcing ribs 111 through the connecting ribs, all the first reinforcing ribs 111 are connected as a whole, so that the first reinforcing ribs 111 are more effectively utilized to improve the stiffness at the first connecting hole 21, which is beneficial to further improve the stiffness and natural mode of the electric control cover plate 10 and reduce the radiation noise of the motor controller.
[0068] Alternatively, if Figure 1 and Figure 2 As shown, one end of the first reinforcing rib 111 away from the connecting edge 2 is connected to the connecting rib.
[0069] For example, one end of the first reinforcing rib 111 at one short side close to the other short side is connected to the connecting rib. One end of the first reinforcing rib 111 at one long side close to the other long side is connected to the connecting rib.
[0070] It is understandable that the end of the first reinforcing rib 111 close to the connecting edge 2 can be connected through the connecting edge 2. Therefore, all the first reinforcing ribs 111 can be effectively connected as a whole by only connecting the end of the first reinforcing rib 111 away from the connecting edge 2. Therefore, when the number of connecting ribs is small, the stiffness and natural mode of the electric control cover plate 10 can be effectively improved, which is conducive to the lightweight design of the electric control cover plate 10.
[0071] Optionally, there are multiple connecting ribs, and two adjacent connecting ribs are connected.
[0072] By setting the number of connecting ribs to be multiple and connecting two adjacent connecting ribs, all the first reinforcing ribs 111 are connected by the connecting ribs, and it is convenient to design the shape and size of each connecting rib according to the position, size and strength requirements of each first reinforcing rib 111, thereby facilitating the lightweight design of the electric control cover plate 10 when the stiffness and natural mode of the electric control cover plate 10 are good.
[0073] Alternatively, if Figure 1As shown, one part of the connecting ribs is the second reinforcing rib 112, which is in the shape of a long strip. Another part of the connecting ribs is the third reinforcing rib 113, which is in the shape of a ring. The ring may be a circular ring, a rectangular ring, an elliptical ring, etc.
[0074] It is understandable that the second reinforcing rib 112 in the shape of a long strip can realize the connection of multiple reinforcing ribs in the same extension direction, and the third reinforcing rib 113 in the shape of a ring can realize the connection of reinforcing ribs in different extension directions. Therefore, a part of the connecting ribs is set in the shape of a long strip, and a part of the connecting ribs is set in the shape of a ring, so as to facilitate the connection of the reinforcing ribs in the first reinforcement area 11. In addition, the third reinforcing rib 113 in the shape of a ring can also reduce the stress concentration problem at the connection of the reinforcing ribs, which is beneficial to improve the strength of the electric control cover plate 10 and facilitate the manufacture of the electric control cover plate 10.
[0075] Alternatively, if Figure 1 and Figure 2 As shown, the number of the third reinforcing ribs 113 is at least two, and the first connecting hole 21 is arranged between two of the third reinforcing ribs 113 in the length direction of the connecting edge 2 .
[0076] For example, Figure 1 and Figure 2 As shown, the number of the third reinforcing ribs 113 is two, and the connecting line between the two third reinforcing ribs 113 and the corresponding first connecting holes 21 is a triangle.
[0077] Thus, the inner surface of the electric control cover plate 10 can be supported more effectively, the rigidity and natural mode of the electric control cover plate 10 can be further improved, and the radiation noise of the motor controller can be reduced.
[0078] Alternatively, if Figure 2 As shown, at least one second reinforcing rib 112 is a parallel rib 1121, which is disposed between two adjacent third reinforcing ribs 113 in the same first reinforcing area 11 in the length direction of the connecting edge 2. The extending direction of the parallel rib 1121 is parallel to the extending direction of the connecting edge 2.
[0079] For example, Figure 2 As shown, there is a second reinforcing rib 112 as a parallel rib 1121 at each of the long sides and one of the short sides, and the extension direction of the parallel rib 1121 at the short side is parallel to the extension direction of the short side, and the extension direction of the parallel rib 1121 at the long side is parallel to the extension direction of the long side.
[0080] By providing the parallel ribs 1121, the structure of the second reinforcing ribs 112 is simple, and it is convenient to connect multiple first reinforcing ribs 111 with the same maximum distance to the connecting edge 2. Thus, while ensuring the overall rigidity of the electric control cover plate 10, it is convenient to process and manufacture the electric control cover plate 10.
[0081] Optionally, at least one second reinforcing rib 112 is an inclined rib 1122, which is arranged on the same side of all third reinforcing ribs 113 in the same first reinforcing area 11 in the length direction of the connecting edge 2. The inclined rib 1122 gradually inclines from the direction away from the third reinforcing rib 113 to the direction close to the connecting edge 2.
[0082] For example, Figure 2 As shown, two second reinforcing ribs 112 at the long side and the short side are inclined ribs 1122 , and the two inclined ribs 1122 in the same first reinforcing area 11 are respectively arranged on both sides of the third reinforcing rib 113 .
[0083] By providing the inclined ribs 1122, the structure of the second reinforcing ribs 112 is simple, and it is convenient to connect multiple first reinforcing ribs 111 with different maximum distances to the connecting edge 2. Thus, while ensuring the overall rigidity of the electric control cover plate 10, it is convenient to process and manufacture the electric control cover plate 10.
[0084] Alternatively, if Figure 2 As shown, at least one third reinforcing rib 113 is an avoidance rib 1131, and the avoidance rib 1131 is arranged between two adjacent third reinforcing ribs 113 in the same first reinforcing area 11 in the length direction of the connecting edge 2. The avoidance rib 1131 encloses an avoidance space. The avoidance space is used to avoid the components inside the motor controller; the ring shape can be a circular ring, a rectangular ring, an elliptical ring, etc.
[0085] By providing the avoidance ribs 1131, the components inside the motor controller can be effectively avoided while connecting the plurality of first reinforcing ribs 111. Thus, the layout design of the components inside the motor controller is facilitated while ensuring the overall rigidity of the electric control cover 10.
[0086] Optionally, the angle between the inclined rib 1122 and the parallel rib 1121 is 30° to 60°.
[0087] For example, the angle between the inclined ribs 1122 and the parallel ribs 1121 at the short sides is 45°, and the angle between the inclined ribs 1122 and the parallel ribs 1121 at the long sides is 30°.
[0088] By setting the included angle between the inclined ribs 1122 and the parallel ribs 1121 to be 30° to 60°, the electric control cover plate 10 can be made lighter when the rigidity of the electric control cover plate 10 is good.
[0089] Alternatively, if Figure 1 and Figure 2 As shown, the first reinforcement regions 11 are arranged symmetrically along the extension direction of the corresponding connecting edges 2 .
[0090] For example, the first reinforcement regions 11 at the short sides are symmetrically arranged along the extending direction of the short sides, and the first reinforcement regions 11 at the long sides are symmetrically arranged along the extending direction of the long sides.
[0091] By arranging the first reinforcement areas 11 symmetrically along the extension direction of the corresponding connecting edges 2 , not only is it convenient to design and manufacture the electric control cover plate 10 , but also the consistency of various parts of the electric control cover plate 10 can be improved.
[0092] In some embodiments, Figure 1 and Figure 2 As shown, the inner surface of the cover body 1 is provided with a second reinforcement area 12 in the middle of the cover body 1, and the second reinforcement area 12 is provided with reinforcement ribs. The reinforcement ribs in the second reinforcement area 12 are connected to the reinforcement ribs in the first reinforcement area 11.
[0093] By setting a second reinforcement area 12 in the middle of the cover plate body 1, and connecting the reinforcement ribs in the second reinforcement area 12 with the reinforcement ribs in the first reinforcement area 11, the reinforcement ribs of multiple first reinforcement areas 11 are connected as a whole through the reinforcement ribs in the second reinforcement area 12, thereby effectively improving the stiffness and natural mode of the electric control cover plate 10 and reducing the radiation noise of the motor controller.
[0094] Alternatively, if Figure 1 As shown, at least one reinforcing rib provided in the second reinforcing area 12 is a fourth reinforcing rib 121, and the extension direction of the fourth reinforcing rib 121 is parallel to the length direction (X direction) of the cover body 1. The reinforcing ribs of two first reinforcing areas 11 adjacently provided along the length direction (X direction) of the cover body 1 are connected by the fourth reinforcing rib 121.
[0095] For example, Figure 2 As shown, the extending direction of the fourth reinforcing rib 121 is consistent with the X direction, and both ends of the fourth reinforcing rib 121 are respectively connected to the third reinforcing rib 113 adjacently arranged in the X direction.
[0096] Alternatively, if Figure 2 As shown, at least one reinforcing rib provided in the second reinforcing area 12 is a fifth reinforcing rib 122, and the extension direction of the fifth reinforcing rib 122 is parallel to the width direction (Y direction) of the cover body 1. The reinforcing ribs in two adjacent first reinforcing areas 11 along the width direction (Y direction) of the cover body 1 are connected by the fifth reinforcing rib 122.
[0097] For example, Figure 2 As shown, the extension direction of the fifth reinforcing rib 122 is consistent with the Y direction, and both ends of the fifth reinforcing rib 122 are respectively connected to the third reinforcing rib 113 adjacently arranged in the Y direction.
[0098] Alternatively, if Figure 2As shown, at least one reinforcing rib provided in the second reinforcing area 12 is a sixth reinforcing rib 123, and the extension direction of the sixth reinforcing rib 123 intersects both the length direction (X direction) of the cover body 1 and the width direction (Y direction) of the cover body 1. The reinforcing ribs in two adjacent first reinforcing areas 11 arranged along the circumference of the cover body 1 are connected by the sixth reinforcing rib 123.
[0099] For example, Figure 2 As shown, the extension direction of the sixth reinforcing rib 123 intersects both the Y direction and the X direction, and both ends of the fifth reinforcing rib 122 are respectively connected to two adjacent third reinforcing ribs 113 at the short side and the long side.
[0100] By arranging the fourth reinforcing rib 121, the fifth reinforcing rib 122 and the sixth reinforcing rib 123 in the second reinforcing area 12, the stiffness and the natural mode of the middle part of the cover plate body 1 can be effectively improved when the number of reinforcing ribs in the second reinforcing area 12 is small, thereby improving the modal performance of the electric control cover plate 10 while reducing the weight of the electric control cover plate 10 and reducing the radiation noise of the motor controller.
[0101] Optionally, the angle between any two of the first reinforcing rib 111 , the second reinforcing rib 112 , the fourth reinforcing rib 121 , the fifth reinforcing rib 122 and the sixth reinforcing rib 123 is greater than or equal to 30°.

[0104] Therefore, while ensuring the modal performance of the electric control cover plate 10, the internal space of the cover plate body 1 occupied by the reinforcing ribs is reduced, which facilitates the layout design of the internal components of the motor controller.
[0105] Alternatively, if Figures 1 to 4 , Figure 6 As shown, the cover body 1 is provided with a mounting hole 13 for mounting the filter 201, and an annular recessed groove 131 is provided at the mounting hole 13, and the recessed groove 131 is arranged around the mounting hole 13.

[0106] By providing the sink groove 131 at the mounting hole 13 , the weight of the cover plate body 1 can be reduced, which is beneficial to the lightweight design of the electric control cover plate 10 .
[0107] By arranging a plurality of seventh reinforcing ribs 132 in the recess 131 , the rigidity of the mounting hole 13 can be effectively improved, the deformation of the electric control cover 10 when the filter 201 is pressed or pulled out can be reduced, and the reliability of the motor controller 100 can be improved.
[0108] Alternatively, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the connecting edge 2 is provided with a second connecting hole 22 at the end portion in the length direction thereof.
[0109] By providing the first connection hole 21 in the middle of the connection edge 2 and providing the second connection hole 22 at the end of the connection edge 2 , the connection area of the electric control cover plate 10 can be increased, and the reliability of the motor controller 100 can be improved.

[0111] For example, the first connection hole 21 and the second connection hole 22 are both disposed on the boss 23 .
[0112] By setting a boss 23 on the connecting edge 2 and setting at least one of the first connecting hole 21 and the second connecting hole 22 on the boss 23, the stiffness at the first connecting hole 21 and the second connecting hole 22 can be further increased, the modal performance of the electric control cover plate 10 can be further improved, and the radiation noise of the motor controller 100 can be reduced.
[0113] Optionally, at least a portion of the annular frame 102 is recessed to have a gap with the boss 23 .

Thus, the installation of the electric control cover plate 10 is facilitated.
[0115] Optionally, an eighth reinforcing rib 24 is provided on the outer surface of the connecting edge 2 , and the boss 23 and the annular frame 102 are connected via the eighth reinforcing rib 24 .
[0116] The eighth reinforcing rib 24 can increase the force transmission path between the boss 23 and the annular frame 102, further improve the stiffness of the first connecting hole 21 and the second connecting hole 22, improve the modal performance of the electric control cover plate 10, and reduce the radiation noise of the motor controller.
[0117] In some embodiments, a plurality of connecting edges form an annular ring body, and an annular sealing groove 25 is provided on the inner surface of the ring body, and the sealing groove 25 is used to accommodate a sealing ring. The distance between the sealing groove 25 and the edge of the connecting edge 2 close to the cover body 1 is greater than or equal to 2 mm.
[0118] By providing the sealing groove 25 , the sealing performance at the mounting surface of the electric control cover plate 10 can be improved, thereby improving the sealing performance of the motor controller 100 .
[0119] Optionally, the electric control cover plate 10 is integrally injection molded, and the demoulding direction of the reinforcing ribs in the first reinforcement area 11 and the second reinforcement area 12 is both inward. That is, the cover plate body 1 and the plurality of connecting edges 2 are integrally injection molded. The demoulding direction is inward, which can be understood as: the demoulding direction is away from the outer surface of the cover plate body 1.
[0120] By integrally injecting the electric control cover plate 10 , on the one hand, it is convenient to process and manufacture the electric control cover plate 10 , which is helpful to reduce the cost of the electric control cover plate 10 ; on the other hand, it is beneficial to the lightweight design of the electric control cover plate 10 .

The first screw 40 passes through the first connecting hole 21 and is threadedly connected to the first fixing hole 202, and the second screw 50 passes through the second connecting hole 22 and is threadedly connected to the second fixing hole, thereby realizing the connection between the controller body 20 and the electric control cover plate 10.
[0124] Alternatively, if Figures 6 to 8 As shown, the motor controller 100 further includes an upper cover plate 30 , which is disposed on a side of the controller body 20 facing away from the electric control cover plate 10 , and is connected to the controller body 20 .
[0125] For example, the controller body 20 is provided with a third fixing hole 203, the upper cover plate 30 is provided with a third connecting hole 301, and the third connecting hole 301 and the third fixing hole 203 are connected by a fastener, which may be a bolt, a screw, a rivet, or the like.
[0126] Alternatively, if Figure 6As shown, a vibration isolation glue 302 is provided on the side of the upper cover plate 30 facing the controller body 20 .
[0127] The vibration isolation glue 302 can reduce the vibration transmitted to the controller body 20 , thereby further reducing the noise of the motor controller 100 .
[0128] The vehicle of the embodiment of the present disclosure includes the motor controller 100 described in any of the above embodiments.
