[0022] In the present application, unless otherwise specified and limited, the terms such as "connected", "connected", "stacked" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] The present application provides a controller assembly and a vehicle, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. Moreover, in the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0024] Reference Figure 1 and Figure 2An embodiment of the present application provides a vehicle, which can include a front compartment 200, a cab 300, and a controller assembly 100. The controller assembly 100 can be installed in the front compartment of the vehicle or other positions of the vehicle. In the present application, the controller assembly 100 is taken as an example to be installed in the front compartment 200 of the vehicle. The controller assembly 100 has a first direction X, a second direction Z, and a third direction Y perpendicular to each other, the first direction X is the length direction of the controller assembly 100, the second direction Z is the height direction of the controller assembly 100, and the third direction Y is the width direction of the controller assembly 100. When the controller assembly 100 is installed in the front compartment 200 of the vehicle, the first direction X is parallel to the width direction of the vehicle, the second direction Z is parallel to the height direction of the vehicle, and the third direction Y is parallel to the length direction of the vehicle.

[0025] With reference to Figure 3 and Figure 4 , the controller assembly 100 can include a first integrated module 1 and a second integrated module 2, which are arranged in a stacked manner in the second direction Z. In the second direction Z, the first integrated module 1 can be arranged above the second integrated module 2, or the second integrated module 2 can be arranged above the first integrated module 1. In the present embodiment, the first integrated module 1 is arranged above the second integrated module 2. Compared with the first integrated module 1 and the second integrated module 2 arranged in a flat manner in the third direction Y, the first integrated module 1 and the second integrated module 2 arranged in a stacked manner can reduce the size of the controller assembly 100 in the third direction Y, i.e., reduce the size of the controller assembly 100 in the length direction of the vehicle, and thus more collision energy absorption space is reserved for the front compartment 200.

[0026] As an example, with reference to Figure 2When the controller assembly 100 is installed in the front compartment 200 of the vehicle, the controller assembly 100 can divide the front compartment 200 into a front crash zone 210 and a rear crash zone 220, the front crash zone 210 being located on the side of the controller assembly 100 away from the driver's cabin 300, and the rear crash zone 220 being located on the side of the controller assembly 100 close to the driver's cabin 300. In the third direction Y, the total length of the front compartment 200 is W, the length of the front crash zone 210 is W1, the width of the controller assembly 100 is W2, and the length of the rear crash zone 220 is W3, W = W1 + W2 + W3. With the total length of the front compartment 200 being W remaining unchanged, the present application can reduce the width of the controller assembly 100 in the third direction Y by stacking the first integrated module 1 and the second integrated module 2 in the second direction Z, thereby increasing the sum of the length of the front crash zone 210 and the length of the rear crash zone 220, and further increasing the crash energy absorption space of the front compartment 200. In the arrangement of the front compartment 200, high-voltage and low-voltage lines and the like inevitably need to pass through the front crash zone 210 and the rear crash zone 220 to realize the connection and communication of high-voltage and low-voltage of the whole vehicle. The increase in the size of the front crash zone 210 and the rear crash zone 220 in the third direction Y can reduce the risk of cutting the high-voltage and low-voltage lines when the controller assembly 100 is crashed, thereby reducing the risk of low-voltage control interruption and high-voltage short circuit or leakage, and further improving the safety of the whole vehicle.

[0027] Specifically, referring to Figure 3 and Figure 4 , the first integrated module 1 can include a first box body 11, and a power supply module 12 and a high-voltage distribution unit 13 at least partially disposed in the first box body 11 and connected to each other.

[0028] Referring to Figure 4 and Figure 5 , the second integrated module 2 can include a second box body 21, and a filter assembly 22, a support capacitor 23, an integrated board assembly 24, and an output terminal 25 at least partially disposed in the second box body 21 and connected in sequence in the first direction X. The filter assembly 22 can be connected with the high-voltage distribution unit 13, and the integrated board assembly 24 can be connected with the power supply module 12 through a low-voltage control wire harness 4.

[0029] As an example, referring to Figure 6 to Figure 8 , the filter assembly 22 can be connected with an external power source such as a vehicle-mounted battery through a busbar 26, and the filter assembly 22 is used to filter out high-frequency interference and harmonic components in the input current to avoid interference signals affecting the normal work of the integrated board assembly 24. The integrated board assembly 24 can include a power module 241 and a circuit device 242, and the power module 241 and the output terminal 25 can be disposed on the side of the circuit device 242 away from the first module. The power module 241 is used to convert direct current power into three-phase alternating current power. Referring to Figure 9 andFigure 10 The circuit device 242 can include a first circuit board 2421, and a low-voltage signal connector 2422 and a rotary connector 2423 arranged on the first circuit board 2421. The low-voltage signal connector 2422 is used for communication connection with the vehicle, and the rotary connector 2423 is used for connection with the vehicle motor (not shown) to obtain parameters such as position, speed, and temperature of the vehicle motor.

[0030] The support capacitor 23 can be a thin film capacitor or an electrolytic capacitor, and can be connected between the filter assembly 22 and the power module 241. The support capacitor 23 is used to stabilize the voltage, absorb voltage fluctuations caused by switching actions of the power module 241, ensure the stability of the voltage, and improve the working reliability and prolong the service life of the power module 241. One end of the output terminal 25 can be connected with the power module 241, and the one end of the output terminal 25 can be electrically connected with the three-phase output end of the power module 241 by bolt connection or welding. The other end of the output terminal 25 can extend to the outside of the second box 21 and be connected with the three-phase input end of the vehicle motor, so as to output the converted three-phase alternating current to the vehicle motor and drive the vehicle motor to operate. The output terminal 25 can be a three-phase copper bar assembly, and can be made of high-conductivity copper material, and the surface of the output terminal 25 can be treated by tin plating or silver plating to reduce the contact resistance and loss.

[0031] In the present application, the controller assembly 100 is improved in integration by arranging the first integrated module 1 and the second integrated module 2, thereby reducing the number of parts and connection wires, reducing the manufacturing cost and the weight of the whole vehicle, simplifying the assembly process, and improving the production efficiency. The first integrated module 1 and the second integrated module 2 are arranged in the second direction Z, and the filter assembly 22, the support capacitor 23, the integrated board assembly 24, and the output terminal 25 are arranged in the first direction X in the second box 21, thereby reducing the size of the controller assembly 100 in the third direction Y, increasing the collision energy absorption space of the front compartment 200, and reducing the risk of the controller assembly 100 invading the driver's cabin 300. At the same time, the wider collision energy absorption space of the front compartment 200 reduces the damage probability of the high-voltage and low-voltage lines during the collision, reduces the risk of low-voltage control interruption and high-voltage electric shock, and improves the safety of the whole vehicle. In addition, the first box 11 and the second box 21 can reduce the mutual electromagnetic interference between different components, and improve the working stability of the whole machine in a complex electromagnetic environment.

[0032] In some embodiments, with reference to Figure 4The controller assembly 100 can further include a heat conduction assembly 3, which can include a plurality of heat conduction pads 31. The heat conduction pads 31 can be made of flexible materials with high thermal conductivity, and the heat generating components can be tightly attached to the first cabinet 11 or the second cabinet 21 through the heat conduction pads 31, so as to reduce the contact thermal resistance, quickly conduct the heat, and thus improve the heat dissipation efficiency.

[0033] Referring to Figure 4 and Figure 9 , the plurality of heat conduction pads 31 can include first heat conduction pads 311, which can be arranged on at least one side of the filter assembly 22 in the second direction Z. In the embodiment, the first heat conduction pads 311 can be arranged above and below the filter assembly 22 in the second direction Z, and the first heat conduction pads 311 can conduct the heat generated by the filter assembly 22 during operation to the first cabinet 11 and the second cabinet 21, so as to realize bidirectional heat dissipation and quickly dissipate the heat generated by the filter assembly 22 during operation.

[0034] Referring to Figure 4 and Figure 9 , the plurality of heat conduction pads 31 can include second heat conduction pads 312, which can be arranged on at least one side of the support capacitor 23 in the second direction Z. In the embodiment, the second heat conduction pads 312 can be arranged above and below the support capacitor 23 in the second direction Z, and the second heat conduction pads 312 can conduct the heat generated by the support capacitor 23 during operation to the first cabinet 11 and the second cabinet 21, so as to realize bidirectional heat dissipation and quickly dissipate the heat generated by the support capacitor 23 during charging and discharging.

[0035] Referring to Figure 4 and Figure 9 , the plurality of heat conduction pads 31 can include third heat conduction pads 313, which are arranged on at least one side of the one-piece board assembly 24 in the second direction Z. In the embodiment, the third heat conduction pads 313 can be arranged above the one-piece board assembly 24 in the second direction Z, so as to avoid interference between the third heat conduction pads 313 and the power module 241, the output terminal 25, etc. The third heat conduction pads 313 can efficiently conduct the heat of the core heat generating components such as the power module 241 in the one-piece board assembly 24 to the first cabinet 11.

[0036] The multi-position and targeted arrangement of the heat conduction pads 31 ensures that the heat of each main heat generating component can be dissipated in time, avoids local overheating, improves the working stability of the controller assembly 100, and prolongs the service life of the controller assembly 100. In some embodiments, when the second cabinet 21 includes a second upper cover 213, the heat conduction pads 31 arranged above the filter assembly 22, the support capacitor 23, and the one-piece board assembly 24 in the second direction Z can conduct the heat to the second cabinet 21.

[0037] In some embodiments, referring toFigure 9 to Figure 13 The heat conduction assembly 3 can further include a liquid cooling water channel 32, which can be distributed in at least one of the first box 11 and the second box 21. That is, the liquid cooling water channel 32 can be distributed in the first box 11, the liquid cooling water channel 32 can also be distributed in the second box 21, or the liquid cooling water channel 32 can be distributed in the first box 11 and the second box 21 at the same time. In the present embodiment, the liquid cooling water channel 32 is distributed in the first box 11 and the second box 21 at the same time. The liquid cooling water channel 32 can further improve the heat dissipation efficiency, further ensure that the heat of each main heat generating component can be dissipated in time, avoid local overheating, further improve the working stability of the controller assembly 100 and prolong the service life of the controller assembly 100.

[0038] When the liquid cooling water channel 32 is distributed in the first box 11 and the second box 21, the liquid cooling water channel 32 can include a first cooling water channel 321 and a second cooling water channel 322. The first cooling water channel 321 can be arranged in the first box 11, and the second cooling water channel 322 can be arranged in the second box 21. Among them, the first cooling water channel 321 and the second cooling water channel 322 can be communicated with each other, and the first cooling water channel 321 and the second cooling water channel 322 adopt the design of the liquid cooling water channel 32 communicated in up and down, integrating the heat dissipation of the first integrated module 1 and the second integrated module 2 as a whole, and the cooling liquid sequentially cools each heat generating component in the circulation process, which has high heat dissipation efficiency, compact water channel structure, does not occupy too much space, and is beneficial to the miniaturization design of the controller assembly 100.

[0039] Alternatively, the first cooling water channel 321 and the second cooling water channel 322 can be independently arranged to meet different heat dissipation requirements. The independent design of the first cooling water channel 321 and the second cooling water channel 322 can control the cooling liquid flow and temperature according to the heat power of each module, realize more accurate heat dissipation control, and be suitable for scenes with extremely high heat dissipation requirements.

[0040] As an example, reference is made to Figure 9 to Figure 13The first cooling water path 321 can be formed by the housing of the power module 12, and the second cooling water path 322 can be formed by the second box body 21. The liquid cooling water channel 32 can further include an inlet water path 323, an outlet water path 324, a first water path connecting portion 325, a second water path connecting portion 326, and a third water path connecting portion 327. The inlet water path 323 can be arranged on the first box body 11, and the outlet water path 324 can be arranged on the second box body 21.

[0058] In some embodiments, the first box body 11 and the second box body 21 can also be provided with reinforcing ribs, which can enhance the structural strength of the first box body 11 and the second box body 21.

[0059] In some embodiments, referring to Figure 20 to Figure 22 The filter assembly 22 can adopt a π-type (CLC, capacitor-inductor-capacitor) filter topology, and can include a magnetic core 221, a first connecting piece 222, and a second connecting piece 223. The magnetic core 221 is, for example, a nanocrystalline magnetic ring, ferrite, or the like. In the embodiment, the magnetic core 221 is a nanocrystalline magnetic ring. Although ferrite has advantages in cost and low-frequency, low-power applications, in the extreme application scenario of the controller assembly 100 of the vehicle, which has high voltage, large current, high switching frequency, wide temperature range, strong EMI (Electromagnetic Interference) challenge, and strict space limitation, the nanocrystalline magnetic ring has overwhelming advantages in terms of its super-high saturation magnetic flux density, ultra-low high-frequency loss, excellent temperature stability, and wide-band high-impedance comprehensive performance. It is a better choice for the filter assembly 22 (especially common-mode inductance). The system-level reliability, efficiency, EMC (Electromagnetic Compatibility) performance, and miniaturization benefits brought by the nanocrystalline magnetic ring far exceed the increase in material cost. In the busbar 26 filtering of the controller assembly 100, the CLC filter topology has high ripple attenuation rate and noise suppression capability.

[0060] Referring to Figure 23 and Figure 24 The first connecting piece 222 can include a first insulating shell 2221 and a first conductive strip 2222 partially covered in the first insulating shell 2221, and the first conductive strip 2222 can pass through the magnetic core 221. The second connecting piece 223 can include a second insulating shell 2231 and a second conductive strip 2232 partially covered in the second insulating shell 2231, and the second conductive strip 2232 can pass through the magnetic core 221. One end of the first conductive strip 2222 and the second conductive strip 2232 can be connected with the busbar 26 respectively, and the other end of the first conductive strip 2222 and the second conductive strip 2232 can be connected with the support capacitor 23 respectively.

[0061] Among them, referring to Figure 23 andFigure 24 The second conductive row 2232 passes through the magnetic core 221 and is arranged in a stack with the first conductive row 2222 in the magnetic core 221, that is, the first conductive row 2222 and the second conductive row 2232 can be parallel to each other and pass through the inner hole of the magnetic core 221 together. The core advantage of this stack design is that it can significantly reduce the size of the inner hole of the magnetic core 221. According to the inductance calculation formula of the nanocrystalline magnetic ring:

[0062] Wherein, L: inductance, H; μ0: vacuum permeability, H / m, the value is 4π×10 -7 ; μ r : relative permeability of nanocrystalline magnetic ring, dimensionless, typical value 10k~50k; h: height of nanocrystalline magnetic ring; t: thickness of nanocrystalline magnetic ring; D: outer diameter of nanocrystalline magnetic ring; d: inner diameter of nanocrystalline magnetic ring; D=d+2t.

[0063] In the case of fixed height h and thickness t of the magnetic core 221, the smaller the inner diameter d of the magnetic core 221, the larger the inductance L. In the prior art, the positive and negative copper rows pass through the magnetic core 221 in parallel, and the magnetic core 221 needs to have a larger inner hole to accommodate the two parallel copper rows, resulting in an increase in the length of the magnetic circuit and a decrease in the inductance. The stack arrangement of the first conductive row 2222 and the second conductive row 2232 of the present application can reduce the size of the inner hole of the magnetic core 221, that is, the inner diameter d of the magnetic core 221 is reduced, thereby reducing the volume of the magnetic core 221 and the material cost while increasing the inductance and enhancing the filtering effect.

[0064] The first connecting piece 222 is fixedly connected with the second connecting piece 223, and the first connecting piece 222 and the second connecting piece 223 can be assembled and fixed by bolts or the like to form a complete filtering assembly 22. This split structure facilitates assembly and can solve the problem that the nanocrystalline magnetic ring cannot be split and is difficult to adapt to special-shaped structures.

[0065] In some embodiments, referring to Figure 20 The first connecting piece 222 can further include a power distribution part 2223 arranged on the first insulating shell 2221, the power distribution part 2223 can be connected with the first conductive row 2222 and the second conductive row 2232 respectively, and the power distribution part 2223 is connected with the high-voltage power distribution unit 13. The first conductive row 2222 and the second conductive row 2232 can obtain high-voltage electrical energy from the busbar 26 and distribute it to the high-voltage power distribution unit 13, realizing the integration of the filtering assembly 22 and the power distribution function, reducing the additional power distribution connection structure, and making the overall structure more compact.

[0066] Referring to Figure 22The first connecting member 222 and / or the second connecting member 223 can further integrate at least one safety capacitor 225. The safety capacitor 225 can include a first capacitor 226 and a second capacitor 227. A plurality of safety capacitors 225 and grounding copper bars are arranged between the magnetic core 221, the power distribution part 2223 and the busbar 26. The second connecting member 223 can also be provided with a plurality of safety capacitors 225 and grounding copper bars. As an example, the first connecting member 222 and the second connecting member 223 are each provided with one first capacitor 226 and two second capacitors 227. The first capacitor 226 is used to filter differential mode interference, and the second capacitor 227 is used to filter common mode interference, and the second capacitor 227 is connected with the grounding copper bar to guide the common mode interference signal to the ground. The integrated design of the safety capacitor 225 avoids the space occupation of additional capacitors, simplifies the line connection, and at the same time cooperates with the laminated conductive bar and the magnetic core 221 to form a complete CLC filter loop, which can effectively suppress electromagnetic interference from the power supply, the motor and the external environment, thereby improving the EMC performance of the controller assembly 100.

[0067] In the present application, the filter assembly 22 uses a CLC type filter structure, which greatly reduces the number of safety capacitors 225 and magnetic cores 221 while ensuring filter effect and reducing cost. By laminating the first conductive bar 2222 and the second conductive bar 2232, the volume of the nanocrystalline magnetic ring is reduced, which reduces the cost while improving the inductance of the magnetic core 221, thereby improving the filter effect. The filter assembly 22 integrates the power distribution structure, and the overall structure is compact and smaller in size, thereby improving the overall power density.

[0068] Referring to Figure 20 , the first insulating shell 2221 is provided with a guide structure for guiding the wire nose of the busbar 26, facilitating the assembly of the busbar 26. Referring to Figure 25 and Figure 26 , the first insulating shell 2221 is further provided with a containing cavity for containing the magnetic core 221. The first insulating shell 2221 is further provided with a penetrating hole 2224 for assembling the second conductive bar 2232, and part of the second conductive bar 2232 can be located in the penetrating hole 2224. The first conductive bar 2222 and the second conductive bar 2232 form a laminated structure and isolate the first conductive bar 2222 and the second conductive bar 2232 from each other.

[0069] Referring to Figure 22 and Figure 24The second connecting member 223 can include a second circuit board 224 for connecting the safety capacitor 225, a positive electrode adapter copper bar and a negative electrode adapter copper bar. The positive electrode adapter copper bar is used to connect the first conductive bar 2222 to the second circuit board 224, and the negative electrode adapter copper bar is used to connect the second conductive bar 2232 to the second circuit board 224. The adapter copper bar, the grounding copper bar and the second circuit board 224 can be connected by welding or screws and the like. In some embodiments, the safety capacitor 225 can be crimped with the adapter copper bar or the grounding copper bar without the need to provide the second circuit board 224.
