[0055] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0056] like Figure 1 and Figure 2 As shown, in one embodiment, the capacitor 10 includes a capacitor body 1, a first electrode 2 and a second electrode 3; the polarities of the first electrode 2 and the second electrode 3 are opposite; in a first direction, the first electrode 2 and the second electrode 3 are connected to the same end of the capacitor body 1; the end of the first electrode 2 away from the capacitor body 1 is bent along the second direction to form a first connecting portion 21; the end of the second electrode 3 away from the capacitor body 1 is bent along the second direction to form a second connecting portion 31; the first connecting portion 21 and the second connecting portion 31 are both used to connect to the target electrical component; the first direction and the second direction intersect.

[0057] The first electrode 2 and the second electrode 3 lead out the positive electrode and the negative electrode of the capacitor body 1 respectively, and when in use, the first electrode 2 and the second electrode 3 can be used as the positive and negative electrodes of the capacitor 10. In some scenarios, the first electrode 2 can be the positive electrode and the second electrode 3 can be the negative electrode, or, in other scenarios, the first electrode 2 can be the negative electrode and the second electrode 3 can be the positive electrode.

[0058] In this embodiment, one end of the first electrode 2 away from the capacitor body 1 is bent to form a first connection portion 21, and one end of the second electrode 3 away from the capacitor body 1 is bent to form a second connection portion 31, so that the size of the capacitor 10 in the first direction can be reduced, thereby reducing the layout space of the capacitor 10. When the power module adopts the capacitor 10 of this embodiment, the space required for arranging the power module can be reduced.

[0059] like Figure 3 As shown, the target electrical component may be a power module 20 or the like, wherein when the target electrical component is the power module 20 , the first connection portion 21 and the second connection portion 31 may be connected to the positive and negative electrodes of the power module 20 , respectively.

[0060] Furthermore, the first direction and the second direction may be perpendicular, for example, Figure 1 and Figure 2 In the directions shown, the first direction is parallel to the X axis, and the second direction is parallel to the Z axis. In an actual application scenario, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0061] like Figure 1 As shown, in one embodiment, the first connection portion 21 and the second connection portion 31 extend in the same direction, for example Figure 1In the embodiment, the first connection portion 21 is formed by bending one end of the first electrode 2 away from the capacitor body 1 upward, and the second connection portion 31 is formed by bending one end of the second electrode 3 away from the capacitor body 1 upward.

[0062] Of course, in other embodiments, the first connection portion 21 and the second connection portion 31 extend in different directions respectively. For example, the first connection portion 21 is formed by bending upward at one end of the first electrode 2 away from the capacitor body 1, and the second connection portion 31 is formed by bending downward at one end of the second electrode 3 away from the capacitor body 1.

[0063] It should be understood that the first electrode 2 and the second electrode 3 are insulated from each other.

[0064] In one embodiment, both the first electrode 2 and the second electrode 3 may be copper bars.

[0065] like Figure 1 As shown, in one embodiment, in the third direction, the first connection portion 21 and the second connection portion 31 are spaced apart; the first direction intersects with the third direction, and the second direction intersects with the third direction. Such an arrangement can improve electrical safety.

[0066] Among them, the first direction, the second direction and the third direction may be perpendicular to each other. Figure 1 In the directions shown, the third direction is parallel to the Y-axis.

[0067] like Figure 1 and Figure 2 As shown, in one embodiment, the first electrode 2 includes a first main body portion 22, the first main body portion 22 is respectively connected to the capacitor body 1 and the first connecting portion 21, the first main body portion 22 extends along the first direction, and the first connecting portion 21 is located on the side of the first main body portion 22 away from the capacitor body 1; the second electrode 3 includes a second main body portion 32, the second main body portion 32 is respectively connected to the capacitor body 1 and the second connecting portion 31, the second main body portion 32 extends along the first direction, and the second connecting portion 31 is located on the side of the second main body portion 32 away from the capacitor body 1.

[0068] The first connecting portion 21 , the first main body portion 22 , the second connecting portion 31 and the second main body portion 32 may all be flat plate structures.

[0069] In addition, the first connecting portion 21 and the first main body 22 may be arranged vertically, and the second connecting portion 31 and the second main body 32 may be arranged vertically. During production, a flat plate may be punched to prepare the first electrode 2. Similarly, another flat plate may be punched to prepare the second electrode 3.

[0070] like Figure 4As shown, in one embodiment, the first body portion 22 and the second body portion 32 are stacked and insulated. During operation, the currents flowing through the two are in opposite directions, so that the magnetic fields generated by the two are partially offset, thereby reducing stray inductance and system loss.

[0071] The first body portion 22 and the second body portion 32 may be stacked in the second direction. In this case, in an orthographic projection of a plane perpendicular to the second direction, the projection of the first body portion 22 and the projection of the second body portion 32 at least partially overlap.

[0072] exist Figure 4 In the example shown, the direction from the second main body portion 32 to the first main body portion 22 is from bottom to top, the first connecting portion 21 protrudes from the first main body portion 22 along the direction from the second main body portion 32 to the first main body portion 22, and the second connecting portion 31 protrudes from the second main body portion 32 along the direction from the second main body portion 32 to the first main body portion 22.

[0073] like Figure 1 and Figure 4 As shown, in one embodiment, an insulating member 4 is disposed between the first electrode 2 and the second electrode 3. The insulating member 4 can separate the first electrode 2 and the second electrode 3, thereby achieving insulation between the first electrode 2 and the second electrode 3.

[0074] In addition, by disposing the insulating member 4, the first electrode 2 and the second electrode 3 can be brought closer together, so that the distance between the first electrode 2 and the second electrode 3 can be reduced while ensuring the insulation performance between the two electrodes.

[0075] like Figures 4 to 6 As shown, in one embodiment, the insulating member 4 includes a plate body 41 and a first baffle 42; the first baffle 42 is connected to an end of the plate body 41 away from the capacitor body 1, and protrudes from the plate body 41 along the second direction, and the first baffle 42 is suitable for electrically isolating the first electrode 2 and the second electrode 3 to avoid electrical connection between the first electrode 2 and the second electrode 3.

[0076] The plate 41 is also suitable for isolating the first electrode 2 and the second electrode 3 , wherein the plate 41 is disposed between the first body portion 22 and the second body portion 32 to electrically isolate the first body portion 22 and the second body portion 32 .

[0077] The first baffle 42 may protrude upward from the plate body 41 or may protrude downward from the plate body 41. The number of the first baffles 42 may be multiple, in which case each first baffle 42 may protrude upward from the plate body 41; or each first baffle 42 may protrude downward from the plate body 41; or a portion of the first baffles 42 may protrude upward from the plate body 41, and another portion of the first baffles 42 may protrude downward from the plate body 41. "Multiple" means greater than or equal to two, and the meaning of "multiple" is the same in each embodiment, which will not be repeated in the following text.

[0078] like Figure 5 As shown, in one embodiment, the first baffle 42 is disposed between the first main body portion 22 and the second connecting portion 31 , and is suitable for electrically isolating the first main body portion 22 from the second connecting portion 31 .

[0079] In this embodiment, the first plate body 41 protrudes along the direction from the second main body portion 32 to the first main body portion 22 (i.e. upward), and, in the first direction, the first plate body 41 is located between the first main body portion 22 and the second connecting portion 31, which can increase the creepage distance between the two and thereby improve electrical safety.

[0080] In one embodiment, the first baffle 42 is disposed between the second body portion 32 and the first connecting portion 21 , and is suitable for electrically isolating the second body portion 32 from the first connecting portion 21 .

[0081] In this embodiment, the first plate body 41 protrudes along the direction from the first main body portion 22 to the second main body portion 32 (i.e., downward), and, in the first direction, the first plate body 41 is located between the second main body portion 32 and the first connecting portion 21, which can increase the creepage distance between the two and thereby improve electrical safety.

[0082] It should be understood that when there are multiple first baffles 42, the first baffle 42 protruding upward from the plate body 41 can be arranged between the first main body 22 and the second connecting part 31, and the first baffle 42 protruding downward from the plate body 41 can be arranged between the second main body 32 and the first connecting part 21.

[0083] In addition, the first baffle 42 and the plate body 41 may be integrally formed.

[0084] like Figure 1 and Figure 6 As shown, in one embodiment, the insulating member 4 further includes a second baffle 43; the second baffle 43 is connected to an end of the plate body 41 away from the capacitor body 1, and protrudes from the plate body 41 along the first direction, and the second baffle 43 is suitable for electrically isolating the first electrode 2 and the second electrode 3. This arrangement can increase the creepage distance between the first electrode 2 and the second electrode 3, thereby improving electrical safety.

[0085] The second baffle plate 43 and the plate body 41 may be integrally formed.

[0086] like Figure 1 As shown, in one embodiment, the second baffle 43 is disposed between adjacent first connection portions 21 and second connection portions 31 , and is suitable for electrically isolating the first connection portions 21 and the second connection portions 31 .

[0087] At this time, the second baffle 43 is mainly used to increase the creepage distance between the adjacent first connection portion 21 and the second connection portion 31. When a second baffle 43 is provided between the adjacent first connection portion 21 and the second connection portion 31, the number of the second baffles 43 provided between the two can be one or more, and when the number of the second baffles 43 provided between the two is more than one, each second baffle 43 can be arranged in sequence along the third direction.

[0088] like Figure 1 As shown, in one embodiment, the first connection portion 21 and the second connection portion 31 are arranged in sequence along the third direction; along the third direction, the second baffle 43 is arranged on a side of the second connection portion 31 away from the first connection portion 21, suitable for electrically isolating the second connection portion 31 from the first main body portion 22. At this time, the second baffle 43 is mainly used to increase the creepage distance between the second connection portion 31 and the first main body portion 22.

[0089] When only one side of the second connection portion 31 has the first connection portion 21 adjacent thereto, a second baffle 43 may be provided on the side of the second connection portion 31 away from the first connection portion 21 in the third direction, thereby improving the electrical safety performance between the first electrode 2 and the second electrode 3 .

[0090] In one embodiment, along the third direction, the second baffle 43 is disposed on a side of the first connection portion 21 away from the second connection portion 31, and is suitable for electrically isolating the first connection portion 21 from the second main body portion 32. When only one side of the first connection portion 21 has the second connection portion 31 adjacent thereto, in the third direction, the second baffle 43 may be disposed on a side of the first connection portion 21 away from the second connection portion 31, so that the electrical safety performance between the first electrode 2 and the second electrode 3 can be improved.

[0091] It should be understood that, in some embodiments, the above-mentioned several configuration modes of the second baffle 43 may exist at the same time, or only one or several of them may exist.

[0092] like Figure 7 As shown, in one embodiment, the insulating member 4 further includes a third baffle 44 ; the third baffle 44 is connected to both ends of the plate body 41 in the third direction and protrudes from the plate body 41 along the second direction, and the third baffle 44 is suitable for isolating the first electrode 2 and the second electrode 3 .

[0093] The third plate 41 may be a plate 41 protruding from the first main body 22 to the second main body 32 (ie, downward), or the third plate 41 may be a plate 41 protruding from the second main body 32 to the first main body 22 (ie, downward).

[0094] exist Figure 7 In the example shown, the two third plates 41 at both ends of the plate 41 both protrude downward from the plate 41. In other embodiments, the two third plates 41 at both ends of the plate 41 may also protrude upward from the plate 41; or, of the two plates 41 at both ends of the plate 41, one third plate 41 protrudes downward from the plate 41, and the other third plate 41 protrudes upward from the plate 41.

[0095] In addition, the third baffle plate 44 and the plate body 41 may be integrally formed.

[0096] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of first connection parts 21 and second connection parts 31 are provided; wherein the first connection parts 21 are sequentially arranged on the first main body part 22 along the third direction, and the second connection parts 31 are sequentially arranged on the second main body part 32 along the third direction. A first groove 221 is provided on the first main body part 22, and the first groove 221 is located between two adjacent first connection parts 21; a second groove 321 is provided on the second main body part 32, and the second groove 321 is located between two adjacent second connection parts 31.

[0097] When welding the target electrical component on the first connection part 21, the first groove 221 can release stress, thereby preventing the first main body 22 from deforming and improving the welding effect. Similarly, when welding the target electrical component on the second connection part 31, the second groove 321 can release stress, thereby preventing the second main body 32 from deforming and improving the welding effect.

[0098] In one embodiment, the first groove 221 and the second groove 321 are located at corresponding positions to form a plurality of output regions on the capacitor 10 , each of which includes a first connecting portion 21 and a second connecting portion 31 .

[0099] The position correspondence between the first groove 221 and the second groove 321 means that: in an orthographic projection of a plane perpendicular to the second direction, the projection of the first groove 221 and the projection of the second groove 321 at least partially overlap. Preferably, in an orthographic projection of a plane perpendicular to the second direction, the projection of the first groove 221 and the projection of the second groove 321 completely overlap, and at this time, the projection of the first groove 221 does not protrude from the projection of the second groove 321, and the projection of the second groove 321 does not protrude from the projection of the first groove 221.

[0100] In addition, the number of the first grooves 221 and the second grooves 321 can be multiple, and the number of the two can be the same. The first grooves 221 are arranged in sequence along the third direction, and the second grooves 321 are arranged in sequence along the third direction, and the positions of one first groove 221 and one second groove 321 correspond.

[0101] When in operation, one output zone can power one target electrical component.

[0102] like Figure 1 and Figure 2 As shown, in one embodiment, the first groove 221 extends along the first direction and connects the end surface of the first main body 22 away from the capacitor body 1, and the second groove 321 extends along the first direction and connects the end surface of the second main body 32 away from the capacitor body 1.

[0103] That is, the first groove 221 extends through the surface of the first main body portion 22 away from the capacitor body 1 , and the second groove 321 extends through the surface of the second main body portion 32 away from the capacitor body 1 .

[0104] In addition, in the second direction, the first groove 221 penetrates the first body portion 22 , and the second groove 321 penetrates the second body portion 32 .

[0105] like Figure 1 As shown, in one embodiment, a plurality of the first connection parts 21 and the second connection parts 31 are provided; in the third direction, the first connection parts 21 and the second connection parts 31 are alternately arranged in sequence.

[0106] The first connection parts 21 are sequentially arranged on the first main body 22 along the third direction, and the second connection parts 31 are sequentially arranged on the second main body 32 along the third direction. The number of the first connection parts 21 and the number of the second connection parts 31 can be the same, and one first connection part 21 corresponds to one second connection part 31. One output area includes a first connection part 21 and a second connection part 31 corresponding thereto.

[0107] like Figure 8 and Fig. 9As shown, in one embodiment, the power module 20 is suitable for connecting the capacitor 10 described in any one of the above embodiments, wherein the power module 20 includes a module body 5, a third electrode 6 and a fourth electrode 7; the third electrode 6 and the fourth electrode 7 have opposite polarities; the end of the third electrode 6 away from the module body 5 is bent along the second direction to form a third connection portion 61, and the third connection portion 61 is suitable for connecting the first connection portion 21; the end of the fourth electrode 7 away from the module body 5 is bent along the second direction to form a fourth connection portion 71, and the fourth connection portion 71 is suitable for connecting the second connection portion 31. This arrangement can further reduce the size of the power module composed of the capacitor 10 and the power module 20 in the first direction, thereby arranging the space required for the power module.

[0108] The module body 5 is used to realize AC-DC conversion, and the third electrode 6 and the fourth electrode 7 are respectively the positive and negative electrodes of the power module 20 .

[0109] In addition, the third electrode 6 and the fourth electrode 7 may be arranged to be spaced apart from each other along the third direction.

[0110] After assembly, the extension direction of the third connection portion 61 can be the same as the direction along the first connection portion 21, for example, both extend upward or both extend downward. Similarly, the extension direction of the fourth connection portion 71 can be the same as the direction along the second connection portion 31, for example, both extend upward or both extend downward.

[0111] like Fig. 9 As shown, in one embodiment, the power module 20 further includes a fifth electrode 8; in the first direction, the fifth electrode 8 is disposed at one end of the module body 5 away from the third electrode 6 and the fourth electrode 7. The fifth electrode 8 is an AC end of the power module 20.

[0112] When the power module 20 is used to convert AC power into DC power, AC power can be introduced into the power module 20 from the fifth electrode 8, and DC power can be output from the third electrode 6 and the fourth electrode 7. When the power module 20 is used to convert DC power into AC power, at this time, DC power can be introduced into the power module 20 from the third electrode 6 and the fourth electrode 7, and AC power can be output from the fifth electrode 8.

[0113] An embodiment of the utility model further provides an electric control system, which includes the capacitor 10 described in any one of the above embodiments and / or the power module 20 described in any one of the above embodiments.

[0114] In one application scenario, the first connection portion 21 and the third connection portion 61 may be connected by the cooperation of bolts and nuts, and the second connection portion 31 and the fourth connection portion 71 may also be connected by the cooperation of bolts and nuts. However, in this manner, the flow capacity between the first electrode 2 and the third electrode 6 and between the second electrode 3 and the fourth electrode 7 is reduced.

[0115] For example, take the method of achieving connection between the first connecting part 21 and the third connecting part 61 through the cooperation of bolts and nuts as an example: in this method, through holes need to be set on the first connecting part 21 and the third connecting part 61, and the diameter of the through hole needs to be larger than the diameter of the bolt. After assembly, the contact area between the first connecting part 21 and the third connecting part 61 will be smaller, thereby reducing the flow capacity between the two.

[0116] In this regard, in one embodiment, the first connection portion 21 is welded to the third connection portion 61, and the second connection portion 31 is welded to the fourth connection portion 71. This can improve the flow capacity between the first electrode 2 and the third electrode 6, and can improve the flow capacity between the second electrode 3 and the fourth electrode 7.

[0117] like Fig.10 As shown, in one embodiment, the electronic control system also includes a support member 9; the support member 9 is at least partially located between the first connecting part 21 and the capacitor body 1, and contacts the surface of the first connecting part 21 close to the capacitor body 1; the support member 9 is at least partially located between the second connecting part 31 and the capacitor body 1, and contacts the surface of the second connecting part 31 close to the capacitor body 1.

[0118] When connecting the first connection part 21 and the third connection part 61, the first connection part 21 can be prevented from tilting toward the capacitor body 1 by the resisting effect of the support member 9, thereby facilitating the connection between the first connection part 21 and the third connection part 61. Similarly, when connecting the second connection part 31 and the fourth connection part 71, the second connection part 31 can be prevented from tilting toward the capacitor body 1 by the resisting effect of the support member 9, thereby facilitating the connection between the second connection part 31 and the fourth connection part 71.

[0119] The area of ​​the support member 9 used to resist the first connection portion 21 is a first resisting area 91 , and the area of ​​the support member 9 used to resist the second connection portion 31 is a second resisting area 92 .

[0120] like Fig.10 As shown, in one embodiment, a first avoidance hole 93 is provided on the surface of the support member 9 in contact with the first connection part 21 to avoid the area where the first connection part 21 and the third connection part 61 are welded (defined as the first area); a second avoidance hole 94 is provided on the surface of the support member 9 in contact with the second connection part 31 to avoid the area where the second connection part 31 and the fourth connection part 71 are welded (defined as the second area).

[0121] like Figure 4 and Figure 5 As shown, a first welding area 211 is provided on the first connection part 21, a second welding area 311 is provided on the second connection part 31, a third welding area 611 is provided on the third connection part 61, and a fourth welding area 711 is provided on the fourth connection part 71; after assembly, the first welding area 211 and the third welding area 611 are welded together to form a first area, and the second welding area 311 and the fourth welding area 711 are welded together to form a second area.

[0122] The first avoidance hole 93 forms a first opening on the surface of the support member 9 close to the first connection portion 21 , and the second avoidance hole 94 forms a second opening on the surface of the support member 9 close to the second connection portion 31 .

[0123] Among them, in the orthographic projection on a plane perpendicular to the first direction, the projection of the first welding area 211, the projection of the third welding area 611 and the projection of the first area are all within the projection of the first opening, and the projection of the second welding area 311, the projection of the fourth welding area 711 and the projection of the second area are all within the projection of the second opening. In this way, the support member 9 avoids the first area through the first avoidance hole 93, and avoids the second area through the second avoidance hole 94.

[0124] When welding the first connection part 21 and the third connection part 61, the heat is mainly concentrated in the first area. At this time, the first avoidance hole 93 can be set to increase the distance between the support member 9 and the first area, thereby avoiding damage to the support member 9 during welding, and such a setting is also conducive to heat dissipation. Similarly, when welding the second connection part 31 and the fourth connection part 71, the heat is mainly concentrated in the second area. At this time, the second avoidance hole 94 can be set to increase the distance between the support member 9 and the second area, thereby avoiding damage to the support member 9 during welding.

[0125] like Fig.10 As shown, in one embodiment, the support member 9 is provided with a mounting hole 95, and the mounting hole 95 is suitable for cooperating with the connecting member so as to connect the support member 9 to the Carrying device superior.

[0126] Among them, the mounting hole 95 can be passed through the support member 9 along the second direction, and the connecting member can be a bolt. In this case, a threaded hole can be set on the supporting device. After the connecting member passes through the support member 9 from the mounting hole 95 and cooperates with the threaded hole on the supporting device, the supporting member 9 can be locked on the supporting device.

[0127] In addition, the mounting hole 95 can be a long hole, and the mounting hole 95 extends along the first direction, so that the mounting position of the support member 9 can be adjusted so that the support member 9 can always contact the first connecting portion 21 and the second connecting portion 31.

[0128] In addition, during assembly, the capacitor 10 and the power module 20 can also be mounted on a carrying device.

[0129] like Figure 8 As shown, in one embodiment, in the first direction, the capacitor body 1, the support member 9, the first connection portion 21, the third connection portion 61 and the module body 5 are arranged in sequence; and / or, in the first direction, the capacitor body 1, the support member 9, the second connection portion 31, the fourth connection portion 71 and the module body 5 are arranged in sequence. This arrangement makes it easier to weld and assemble the capacitor 10 and the power module 20.

[0130] Specifically, during assembly, the capacitor 10 and the power module 20 can be fixed first, and then a laser can be projected from one side of the power module 20 to the third connecting part 61 and the fourth connecting part 71 along the direction from the power module 20 to the capacitor 10 to weld the third connecting part 61 and the first connecting part 21, as well as the fourth connecting part 71 and the second connecting part 31.

[0131] like Fig.11 As shown, in one embodiment, the support member 9 is further provided with a first avoidance groove 96, which is used to avoid the first baffle 42, so as to prevent the first baffle 42 from interfering with the installation of the support member 9. In addition, the support member 9 is provided with a second avoidance groove 97, which is used to avoid the second baffle 43, so as to prevent the second baffle 43 from interfering with the installation of the support member 9. After assembly, at least a portion of the first baffle 42 can be located in the first avoidance groove 96, and at least a portion of the second baffle 43 can be located in the second avoidance groove 97.

[0132] An embodiment of the utility model further provides an electric assembly, which includes the electric control system described in any one of the above embodiments.

[0133] An embodiment of the utility model further provides a vehicle, wherein the electric assembly includes the electric assembly described in any one of the above embodiments.

[0134] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0135] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
