[0034] The controller 100 of the embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0035] Refer to Figure 1 、 Figure 2 According to an embodiment of the present utility model, a controller 100 includes: a housing 10, a power component 20, a filtering component 30, and a capacitor component 40.

[0036] An integrally formed fixing portion 11 is provided inside the housing 10, and a positioning space 111 is provided on the fixing portion 11. The power component 20 is disposed inside the housing 10 and is used to connect to a vehicle motor. The filtering component 30 is disposed inside the housing 10 and is used for filtering. The capacitor component 40 is respectively connected to the power component 20 and the filtering component 30, and the capacitor component 40 is installed in the positioning space 111.

[0037] Among them, the fixing portion 11 is integrally formed with the housing 10, and the fixing portion 11 is formed while the housing 10 is formed. The power component 20, the filtering component 30, and the capacitor component 40 form the power output structure of the controller 100. The power component 20 is a key part responsible for processing and transmitting high voltage and large current, including power semiconductor devices and other related circuits. The main functions of these components are to convert the direct current of the battery into the alternating current required to drive the vehicle motor and to achieve efficient control of the vehicle motor. The filtering component 30 is used to reduce and eliminate electromagnetic interference (EMI) and high-frequency noise in the power system, thereby ensuring the stability and performance of the system. The filtering component 30 may include various inductors, capacitors, and other filter elements.

[0038] In the related art, the controller usually plays a control role, and a capacitor is installed in the controller, but the capacitor has a large volume.

[0039] In the related art, the capacitor has a plastic housing, the battery core of the capacitor is placed inside the plastic housing, and the plastic housing is fixed to the inner wall of the controller by screws. The plastic housing occupies a certain space and requires a certain cost, such as the cost of the mold.

[0040] In the embodiment of the present utility model, an integrally formed fixing portion 11 is provided on the outer shell 10. A positioning space 111 is provided on the fixing portion 11. The capacitor assembly 40 is installed in the positioning space 111. The capacitor assembly 40 is fixed by the fixing portion 11. The capacitor assembly 40 does not need to be provided with an additional plastic housing, thereby optimizing the structure, reducing the size of the capacitor assembly 40, reducing the related costs, and lowering the overall cost.

[0041] For the controller 100 according to the embodiment of the present utility model, by providing an integrally formed fixing portion 11 on the outer shell 10, a positioning space 111 is opened on the fixing portion 11. The capacitor assembly 40 is positioned by the positioning space 111. Compared with the scheme of separately providing a plastic housing to fix the battery cell in the related art, the capacitor assembly 40 of the present utility model does not need to be provided with an additional plastic housing, reducing the size of the capacitor assembly 40, optimizing the structure, reducing the related costs, and lowering the overall cost.

[0042] In some specific embodiments, the material of the outer shell 10 is metal, which improves the strength, and at the same time improves the heat conduction ability and the heat dissipation ability.

[0043] Refer to Figure 2 、 Figure 3 In some embodiments, the fixing portion 11 is configured as a limiting plate. The limiting plate extends inward. The limiting plate defines a positioning groove, and the positioning groove is configured as the positioning space 111.

[0044] Among them, the limiting portion is located inside the outer shell 10 and extends in the direction towards the center of the outer shell 10. It can be that an annular limiting plate encloses a cylindrical positioning space 111, or it can be that multiple limiting plates jointly enclose a polygonal positioning space 111. The positioning space 111 is open.

[0045] In the above scheme, the positioning groove is defined by the inwardly extending limiting plate, and the capacitor assembly 40 is positioned by the positioning groove. The open positioning space 111 facilitates the placement of the capacitor assembly 40.

[0046] In some embodiments, there are multiple limiting plates. The multiple limiting plates are connected end to end, and the multiple limiting plates jointly enclose a positioning groove.

[0047] Among them, the multiple limiting plates are connected in sequence, and the positioning groove jointly enclosed by the multiple limiting plates is a polygonal groove.

[0048] In the above scheme, by setting multiple limiting plates to jointly define a polygonal positioning groove, the incorrect installation of the capacitor assembly 40 is avoided, so that the capacitor assembly 40 can be stably fixed in the positioning groove.

[0049] Specifically, there are four limiting plates, and the four limiting plates jointly define a quadrilateral positioning groove, and the inner wall of the positioning groove fits well with the capacitor assembly 40. Of course, the number of limiting plates can also be other numbers, which will not be elaborated here.

[0050] In some embodiments, a filling and isolating member is provided in the positioning space 111, and at least a part of the capacitor assembly 40 is accommodated in the filling and isolating member.

[0051] Among them, the filling and isolating member fills the positioning space 111, and the filling and isolating member plays a positioning and isolating effect, fixing the capacitor assembly 40 in the positioning space 111, and at the same time preventing foreign objects from contacting the capacitor assembly 40, thereby isolating the capacitor assembly 40.

[0052] In the above solution, by arranging the filling and isolating member to fill the positioning space 111, the capacitor assembly 40 is fixed by the filling and isolating member, and the filling and isolating member also plays an isolating effect, preventing foreign objects from contacting the capacitor assembly 40 and avoiding interference with the capacitor assembly 40, thereby improving the working stability.

[0053] In some embodiments, the filling and isolating member is configured as an insulating member.

[0054] Among them, the insulating member plays an insulating effect and further improves the isolating effect. It can be understood that the capacitor assembly 40 is charged itself and is easily affected by current interference.

[0055] In the above solution, by setting the filling and isolating member as an insulating member, the insulating effect of the insulating member is used to further improve the isolating effect on the capacitor assembly 40, preventing external current from interfering with the internal capacitor assembly 40, and improving the working stability.

[0056] Specifically, the material of the insulating member is epoxy resin, which is convenient, practical and easy to operate.

[0057] Refer to Figure 3 , in some embodiments, the capacitor assembly 40 has opposite first side 41 and second side 42, the first side 41 faces the bottom surface of the positioning space 111, and the thickness of the filling and isolating member located at the part where the second side 42 faces away from the first side 41 is at least 3 mm.

[0058] Among them, the filling and isolating member fills the positioning space 111, the filling and isolating member at least wraps part of the capacitor assembly 40, the thickness of the filling and isolating member is greater than the thickness of the capacitor assembly 40, the filling and isolating member immerses the second side 42, and the thickness of the filling and isolating member is greater than the thickness of the capacitor assembly 40 by at least 3 mm.

[0059] In the above solution, by arranging more filling and isolating members to wrap the capacitor assembly 40, the capacitor assembly 40 is well wrapped, preventing foreign objects from contacting, and improving the working stability.

[0060] Specifically, the thickness of the filling and insulating member located at the portion of the second side surface 42 away from the first side surface 41 is 3 mm, or the thickness of the filling and insulating member located at the portion of the second side surface 42 away from the first side surface 41 is 4 mm, or the thickness of the filling and insulating member located at the portion of the second side surface 42 away from the first side surface 41 is 5 mm. Of course, other values are also possible and will not be elaborated here.

[0061] Referring to Figure 1 , in some embodiments, the power component 20 and the filtering component 30 are respectively disposed on different sides of the capacitor component 40.

[0062] Among them, the power component 20 and the filtering component 30 are distributed around the capacitor component 40. For example, the power component 20 and the filtering component 30 are distributed on adjacent sides of the capacitor component 40, or the power component 20 and the filtering component 30 are distributed on opposite sides of the capacitor component 40.

[0063] In the above solution, by respectively disposing the power component 20 and the filtering component 30 on different sides of the capacitor component 40, the peripheral space of the capacitor component 40 is fully utilized, the space utilization rate is improved, and the overall structure is made compact.

[0064] Referring to Figure 1 , in some embodiments, the power component 20 and the filtering component 30 are disposed on opposite sides of the capacitor component 40.

[0065] Among them, the power component 20 and the filtering component 30 are respectively disposed on opposite sides of the capacitor component 40. For example, the power component 20 and the filtering component 30 are disposed on the upper and lower sides of the capacitor component 40, or the power component 20 and the filtering component 30 are disposed on the left and right sides of the capacitor component 40.

[0066] In the above solution, by disposing the power component 20 and the filtering component 30 on opposite sides of the capacitor component 40, the opposite sides of the capacitor component 40 are fully utilized, the power component 20 and the filtering component 30 do not interfere with each other, the overall stability is ensured, and the operation is more reliable.

[0067] Referring to Figure 4 , in some embodiments, the capacitor component 40 includes: a capacitor core 43, a first electrode plate 44, and a second electrode plate 45.

[0068] The capacitor core 43 has a first polar part and a second polar part. The first electrode plate 44 is connected to the first polar part. The second electrode plate 45 is connected to the second polar part.

[0069] Among them, a first copper bar 441 is provided on the first pole plate 44, and the first copper bar 441 extends to the outside of the positioning space 111 and is connected to the power component 20. A second copper bar 451 is provided on the second pole plate 45, and the second copper bar 451 extends to the outside of the positioning space 111 and is connected to the power component 20.

A fourth copper bar 452 is provided on the second pole plate 45, and the fourth copper bar 452 and the second copper bar 451 are arranged on the opposite side of the second pole plate 45, and the fourth copper bar 452 extends to the outside of the positioning space 111 and is connected to the filter component 30.

[0070] Among them, the first copper busbar 441, the second copper busbar 451, the third copper busbar 442 and the fourth copper busbar 452 play a conductive role. The first copper busbar 441 and the second copper busbar 451 extend to the outside of the positioning space 111 to connect to the power component 20, so that the capacitor component 40 is electrically connected to the power component 20, and the third copper busbar 442 and the fourth copper busbar 452 extend to the outside of the positioning space 111 and connect to the filter component 30, so that the capacitor component 40 is electrically connected to the filter component 30.

[0071] In the above scheme, by arranging the third copper bar 442 and the first copper bar 441 on the opposite side of the first electrode plate 44, and arranging the fourth copper bar 452 and the second copper bar 451 on the opposite side of the second electrode plate 45, the space of each part is fully utilized, so that the first copper bar 441, the second copper bar 451, the third copper bar 442 and the fourth copper bar 452 are reasonably distributed, and the whole structure is compact.
