DETAILED DESCRIPTION

[0046] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0048] The present application provides a vehicle including a power system 1000 .

[0049] The power system 1000 not only serves as a power source to provide power for the vehicle, but also provides electrical energy to each control module 120 of the vehicle, thereby providing a guarantee for the operation and control process of the vehicle.

[0050] like Figure 1 As shown, the power system 1000 of the present application includes a power battery, a battery box 200 and a domain controller component 100.

[0051] The power battery is disposed in the battery box 200. The mounting side 111a of the housing 110 is connected to the battery box 200. The control module 120 is electrically connected to the power battery.

[0052] It can be seen that the power system 1000 provided by the present application directly integrates the domain controller assembly 100 into the battery box 200, making the overall structure of the power system 1000 more compact, effectively saving the installation space of the vehicle and improving the space utilization rate. At the same time, such a setting method enables the battery box 200 to serve as an energy absorption and buffer component of the domain controller assembly 100, improves the safety of the domain controller assembly 100, and ensures its convenience when connected to the power battery, so that workers can complete the maintenance of the domain controller assembly 100 and the power battery in the power system 1000 at the same time, improving the convenience of vehicle maintenance.

[0053] like Figures 2 to 5 As shown, the domain controller assembly 100 of the present application includes a housing 110 and a control module 120. Figure 2 and Figure 3The shell 110 includes a main body 111 and a cover plate 112 covering the main body 111. The main body 111 includes a side wall 1111 and a receiving cavity 1112 formed by the side wall 1111. The control module 120 is installed on the shell 110 and is used to be electrically connected to the power battery. Among them, the main body 111 includes an installation side 111a and a maintenance side 111b that are relatively arranged. The installation side 111a is used to connect to the power battery, and the cover plate 112 is arranged on the maintenance side 111b. The control module 120 includes an electrically connected domain control module 121 and a battery pack circuit breaker unit (Battery energy Distribution Unit, BDU). Reference Figure 4 and Figure 5 The domain control module 121 is disposed in the accommodating cavity 1112 . The battery pack disconnecting unit 122 is disposed on the mounting side 111 a of the main body 111 .

[0054] First, the domain controller component 100 integrates the vehicle's control module 120 into the housing 110 and connects it to the battery box 200, thereby avoiding the problems of scattered installation and difficult wiring of the control module 120, thereby effectively saving the vehicle's installation space and improving space utilization. In addition, the structural setting of the domain controller component 100 also enables workers to complete the inspection and maintenance of each control module 120 on the housing 110, effectively improving the efficiency and convenience of the vehicle during maintenance. Moreover, the housing 110 recorded in this embodiment can integrate the vehicle's domain control module 121 into the accommodating cavity 1112 through the setting of the main body 111, and then cover the accommodating cavity 1112 with the cover plate 112 to effectively protect the domain control module 121. It can be seen that the overall structure of the housing 110 is compact, which further saves the vehicle's installation space and improves space utilization. In addition, the domain controller component 100 of the present embodiment sets the battery pack circuit disconnecting unit 122 on the installation side 111a, so that the battery pack circuit disconnecting unit 122 is wrapped in the domain controller component 100 and the battery case 200, so that the shell 110 and the battery case 200 can both become energy absorption and buffer components of the battery pack circuit disconnecting unit 122. It can be seen that the structural setting of the domain controller component 100 not only improves its compactness, integrity and space utilization, but also provides better protection for the battery pack circuit disconnecting unit 122, thereby improving the overall safety and stability of the vehicle.

[0055] In an optional embodiment, the battery case 200 includes a mounting surface 210 and a mounting opening recessed from the mounting surface 210. The mounting side 111a is connected to the mounting surface 210. The battery pack disconnecting unit 122 is inserted into the battery case 200 from the mounting opening.

[0056] It can be seen that the power system 1000 provided in the present application can directly integrate the domain controller component 100 into the battery box 200, making the overall structure of the power system 1000 more compact, effectively saving the installation space of the vehicle, and improving space utilization. At the same time, such a setting method allows the battery pack circuit breaker unit 122 to be directly inserted into the battery box 200, thereby further improving the protection effect of the domain controller component 100 on the battery pack circuit breaker unit 122, ensuring the safety of the vehicle and the driver and passengers. In addition, such a structural setting makes the power system 1000 more convenient to install, disassemble and repair, improves the convenience of vehicle assembly and maintenance, and thus improves the work efficiency of workers.

[0057] In an optional embodiment, the main body 111 further includes a partition wall 1113 disposed in the accommodating chamber 1112. The partition wall 1113 divides the accommodating chamber 1112 into a first accommodating chamber 1112a and a second accommodating chamber 1112b adjacently distributed along the length direction X of the shell 110. The opening of the first accommodating chamber 1112a faces the maintenance side 111b. The domain control module 121 includes a first module and a second module, the first module being disposed in the first accommodating chamber 1112a, and the second module being disposed in the second accommodating chamber 1112b.

[0058] The setting of the isolation wall 1113 can not only separate the accommodating chamber 1112 into the first accommodating chamber 1112a and the second accommodating chamber 1112b, but also form an electromagnetic barrier between the first accommodating chamber 1112a and the second accommodating chamber 1112b. It can be seen that the structure of the isolation wall 1113 not only improves the orderliness and convenience during the installation of the domain control module 121, but also can avoid electromagnetic interference between the first module and the second module, thereby effectively improving the overall stability of the domain controller assembly 100.

[0059] In an optional embodiment, the main body 111 further includes a partition 1114 and a third accommodating chamber 1112c. The second accommodating chamber 1112b is disposed on a side of the partition 1114 facing the inspection side 111b. The third accommodating chamber 1112c is disposed on a side of the partition 1114 facing the installation side 111a.

[0060] The domain control module 121 includes a third module disposed in the third accommodating cavity 1112c.

[0061] The housing 110 of the present application separates the third accommodating chamber 1112c from the second accommodating chamber 1112b through the provision of the partition 1114, and is used to install the third module. It can be seen that the provision of the partition 1114 effectively separates and plans the installation space of the housing 110, and can also form a shield between the second accommodating chamber 1112b and the third accommodating chamber 1112c. Such a structure not only further improves the convenience and orderliness of the installation of the domain control module 121, but also avoids electromagnetic interference between the second module and the third module, and improves the shielding and isolation effect of the two cavities.

[0062] In an optional embodiment, the side surrounding wall 1111 further includes a first side wall 1111 a and a second side wall 1111 b that are arranged opposite to each other along the height direction Z of the shell 110 .

[0063] The partition plate 1114 is connected to the first side wall 1111a. The second accommodation chamber 1112b is directly connected to the third accommodation chamber 1112c at a side close to the second side wall 1111b. At least part of the third module is exposed in the second accommodation chamber 1112b.

[0064] The structural setting of the partition 1114 enables the second accommodating chamber 1112b and the third accommodating chamber 1112c to be directly connected, thereby facilitating the connection of the wiring harness between the second module and the third module. At the same time, when the worker opens the cover 112 for installation or maintenance, he can not only inspect the second module in the second accommodating chamber 1112b, but also install, repair, inspect, etc. the third module in the third accommodating chamber 1112c. It can be seen that the structural setting of the partition 1114 further improves the space utilization of the vehicle and further improves the convenience of installing and repairing internal components.

[0065] In an optional embodiment, the main body 111 further includes a mounting plate 1115 disposed on the mounting side 111 a. The mounting plate 1115 extends in a direction Y away from the mounting side 111 a. The battery pack disconnecting unit 122 is mounted on the mounting plate 1115 .

[0066] The present application integrates the battery pack disconnecting unit 122 into the housing 110 by setting the mounting plate 1115, which is beneficial to the connection between the battery pack disconnecting unit 122 and other control modules 120, and further improves the space utilization of the vehicle. At the same time, as described above, the battery case 200 includes a mounting surface 210 and a mounting port. The housing 110 is connected to the mounting surface 210. Due to the setting of the mounting plate 1115, the mounting plate 1115 will be inserted into the interior of the battery case 200 through the mounting port, thereby electrically connecting the battery pack disconnecting unit 122 to the power battery. It can be seen that the setting of the mounting plate 1115 also improves the convenience of connecting the battery pack disconnecting unit 122 to the power battery.

[0067] In addition, during the actual use of the vehicle, the battery pack disconnecting unit 122 is the main insurance of the vehicle, and it is easy to cause battery fire when it is damaged by collision. Therefore, the battery pack disconnecting unit 122 is set on the mounting plate 1115 and inserted into the battery box 200, so that the battery pack disconnecting unit 122 is wrapped by the outer shell 110 and the battery box 200. When the vehicle collides, bumps or squeezes, the shell 110, battery box 200 and other components on the outside of the battery pack disconnecting unit 122 can be used as energy absorbing components and collapse zones, thereby effectively protecting the safety of the battery pack disconnecting unit 122, and then ensuring the safety of the driver and the vehicle. It can be seen that the structure of the domain controller component 100 of the present application can further improve the overall safety of the vehicle.

[0068] In an optional embodiment, if Figure 4 and Figure 5 As shown, the main body 111 further includes a first through hole 1116 disposed in the first accommodation cavity 1112a and a second through hole 1117 disposed in the partition 1114. The first through hole 1116 connects the first accommodation cavity 1112a with the mounting side 111a, and the second through hole 1117 connects the second accommodation cavity 1112b with the third accommodation cavity 1112c.

[0069] The first through hole 1116 and the second through hole 1117 are provided to connect the accommodation spaces on both sides of the main body 111, thereby facilitating the mutual connection between the control modules 120 on both sides. Specifically, the first module installed in the first accommodation cavity 1112a can pass the wiring harness through the first through hole 1116, thereby connecting to the battery pack disconnecting unit 122 on the mounting plate 1115. Similarly, the second module installed in the second accommodation cavity 1112b can also pass the wiring harness through the second through hole 1117, thereby connecting to the high-voltage distribution unit 125 in the third accommodation cavity 1112c. It can be seen that the provision of the first through hole 1116 and the second through hole 1117 effectively reduces the wiring difficulty of the domain controller, thereby further improving the integration degree, space utilization and convenience of the domain controller during installation.

[0070] It should be noted that, since the embodiment described in the present application is provided with the first accommodating cavity 1112a, the second accommodating cavity 1112b, the third accommodating cavity 1112c and the mounting plate 1115, the first via hole 1116 and the second via hole 1117 are provided. However, in the embodiment including only the first accommodating cavity 1112a and the mounting plate 1115, only the first via hole 1116 may be provided; or in the embodiment including only the second accommodating cavity 1112b and the third accommodating cavity 1112c, only the second via hole 1117 may be provided. Of course, by analogy, in the embodiment with more installation spaces, more via holes may also be provided to facilitate the connection of the wiring harness, and thus, the present application does not limit this.

The first filter component 1235 is arranged at the input side of the motor controller 123, and the second filter component 1236 is arranged at the output side of the motor controller 123, which are respectively used to perform electromagnetic compatibility protection on the input and output sides of the motor controller 123. One end of the capacitor 1231 close to the input side is electrically connected to the first filter component 1235, and the other end is electrically connected to the inverter module 1232. One end of the inverter module 1232 away from the capacitor 1231 is electrically connected to the current sensor 1234, and a side cover of the inverter module 1232 away from the installation side 111a is provided with a driving board 1233 for driving the inverter module 1232 to work. One end of the current sensor 1234 away from the inverter module 1232 is electrically connected to the second filter component 1236 and is used to monitor the three-phase voltage.

[0074] The high-voltage distribution unit 125 includes a high-voltage relay 1251, a terminal block 1252, and a high-voltage fuse 1253. In the height direction Z of the housing 110, the high-voltage relay 1251 and the high-voltage fuse 1253 are arranged at one end of the third accommodating cavity 1112c close to the second side wall 1111b, and are exposed in the second accommodating cavity 1112b.

[0075] Among them, one end of the terminal block 1252 is electrically connected to the high-voltage distribution unit 125, and the other end extends in a direction away from the second accommodating cavity 1112b, and the terminal 1254 is extended to the mounting plate 1115 for connection with the terminal block of the power battery.

The battery pack disconnecting unit 122 includes a third filter component 1221 and a relay component. The battery pack disconnecting unit 122 is used to be connected to the power system 1000. The third filter component 1221 is arranged close to the input side of the battery pack disconnecting unit 122.

[0077] Among them, the third filter component 1221 includes a current collector 1222 and a main positive fuse 1223 electrically connected to each other. The relay assembly includes a main positive relay 1224, a main negative relay 1225 and a fast charging relay 1226 electrically connected in sequence. The battery pack circuit breaker unit 122 is electrically connected to the high-voltage power distribution unit 125. The high-voltage power distribution unit 125 is used to collect electrical signals from the battery pack circuit breaker unit 122 and control the operation of the relay assembly. The combination module 124 is electrically connected to the high-voltage power distribution unit 125, and the DC converter is electrically connected to the battery pack circuit breaker unit 122. The battery pack circuit breaker unit 122 also includes a fourth filter component 1227, and the fourth filter component 1227 is connected between the combination module 124 and the battery pack circuit breaker unit 122.

[0078] The housing 110 of the present application integrates the domain control module 121 and the battery pack disconnecting unit 122, and also improves the convenience of interconnection between the modules and the orderliness of the wiring harness arrangement through the structural setting of the accommodating cavity 1112, and also ensures that no electromagnetic interference is generated between the modules. It can be seen that the structural setting of the domain controller assembly 100 effectively improves the structural compactness, space utilization, stability and safety of the power system 1000.

[0079] It should be noted that in other optional embodiments, the specific structure and layout of the domain controller component 100 can be adjusted accordingly according to the actual situation. For example, the first module can also be configured to include a combination module 124 composed of a DC converter and an on-board charger, or can be configured to include a high-voltage distribution unit 125, or can be configured to include other components according to the actual structure. Similarly, the second module can also be configured to include a motor controller 123 or a high-voltage distribution unit 125 or other components, and the third module can also be configured to include a motor controller 123 or a combination module 124 or other components. Therefore, this application does not limit this.

[0080] In addition, in the actual assembly process, the combined module 124 can be configured as an integration of a DC converter and an on-board charger as described in the above embodiments, or it can be configured as an integration of a DC converter and a brake system inverter, or it can be integrated by other compatible modules. Of course, it can also be directly replaced with a separate module, such as a DC converter or an on-board charger. It can be seen that the specific components constituting the combined module 124 can be selected accordingly according to the actual vehicle configuration, usage requirements, etc., so this application does not limit this.

[0081] In an optional embodiment, if Figure 6 As shown, the cover plate 112 includes a mounting portion 1122 and a shielding plate 1123. The mounting portion 1122 is disposed on a side of the cover plate 112 facing the main body 111. The domain control module 121 includes a low voltage domain control module (LVDCM) disposed on the mounting portion 1122. The shielding plate 1123 is covered on a side of the low voltage domain control module 126 facing the main body 111.

[0082] The housing 110 of the present application further expands the installation space of the housing 110 and improves the integration level of the domain controller assembly 100 by setting a mounting portion 1122 on the cover plate 112. When the cover plate 112 is covered on the main body 111, the mounting portion 1122 covers the surface of the accommodating cavity 1112, thereby facilitating the connection between the low-voltage domain control module 126 on the mounting portion 1122 and the domain control module 121 in the accommodating cavity 1112. The low-voltage domain control module 126 is electrically connected to the motor controller 123, the low-voltage signal line 1241 of the combination module 124, the high-voltage power distribution unit 125, and the battery pack disconnecting unit 122 through a low-voltage wiring harness, and is used to receive electrical signals and control the motor controller 123, the DC converter, the on-board charger, the high-voltage power distribution unit 125, and the battery pack disconnecting unit 122 to work according to the electrical signals. Among them, the low-voltage domain control module 126 integrates the vehicle control unit (VCU), the MCU control unit and the battery management system (BMS). The setting of the vehicle control unit enables the low-voltage domain control module 126 to collect electrical signals from each module and process and make decisions accordingly; the setting of the MCU control unit can effectively control the motor controller 123 described above; the setting of the battery management system can continuously monitor the state of the power battery, such as voltage, current, temperature, etc., so as to ensure that the power battery operates within a safe range. It can be seen that the structural setting of the low-voltage domain control module 126 can achieve comprehensive control of the vehicle, provide higher safety, better performance and better user experience. At the same time, it can also improve the convenience of connection between each control module 120, reduce the number of wiring harnesses, thereby reducing weight and simplifying the assembly process. In addition, the setting of the shielding plate 1123 can form an electromagnetic barrier between the cover plate 112 and the main body 111, avoiding electromagnetic interference between the domain control module 121 in the accommodating cavity 1112 and the low-voltage domain control module 126.

[0083] In the actual assembly process, the worker first installs the first module, the second module and the third module described above into the corresponding accommodating cavity 1112, then connects each module to the low-voltage domain control module 126 through a wiring harness, and covers the shielding plate 1123 on the surface of the low-voltage domain control module 126 to form an electromagnetic barrier. It can be seen that the setting of the installation part 1122 not only ensures the convenience of interconnection between each control module 120, but also effectively improves the structural integration and compactness of the domain controller assembly 100.

[0084] In an optional embodiment, if Figure 7 and Figure 8As shown, the cover plate 112 also includes a low-voltage jack 1124 and a three-phase jack 1125. The low-voltage domain control module 126 includes a low-voltage plug-in 1261 and a three-phase plug-in 1262. Among them, the low-voltage jack 1124 and the three-phase jack 1125 respectively connect the mounting portion 1122 with the side of the cover plate 112 away from the main body 111. The low-voltage plug-in 1261 and the three-phase plug-in 1262 are respectively arranged through the low-voltage jack 1124 and the three-phase jack 1125, and are exposed on the side of the cover plate 112 away from the main body 111.

[0085] As can be seen from the figure, the low-voltage plug-in 1261 and the three-phase plug-in 1262 of the low-voltage domain control module 126 can be exposed outside the cover plate 112 through the low-voltage jack 1124 and the three-phase jack 1125, thereby facilitating external connection. It can be seen that the structure of the housing 110 is compact, integrated, and highly integrated, and the structure of the housing 110 makes the wiring harness of the domain controller assembly 100 reasonably arranged, easy to repair, and neat in appearance.

[0086] In an optional embodiment, the main body 111 further includes a disassembly opening 113 and a three-phase cover plate 114. The disassembly opening 113 is disposed at one end of the main body 111 close to the three-phase socket 1125. The three-phase plug 1262 is exposed from the disassembly opening 113. The three-phase cover plate 114 is detachably covered on the disassembly opening 113.

[0087] After the cover plate 112 is covered on the main body 111, the worker can check the three-phase plug-in 1262 of the low-voltage domain control module 126 through the disassembly port 113 on the side of the first accommodating cavity 1112a, and can directly connect the low-voltage domain control module 126 with the motor controller 123 through the disassembly port 113, so there is no need to remove the cover plate 112 as a whole, thereby further improving the convenience of workers during maintenance and installation. At the same time, the setting of the three-phase cover plate 114 plays a better protective role for the control module 120 inside the housing 110, and can also clearly indicate the specific opening position of the cover to the maintenance worker.

[0088] In an optional embodiment, the cover plate 112 includes an inspection port 1121 , wherein the inspection port 1121 is in communication with the accommodating cavity 1112 , and the domain control module 121 is exposed from the inspection port 1121 .

[0089] Since the shell 110 is provided with an inspection port 1121 on the cover plate 112, and the domain control module 121 can be exposed to the inspection port 1121, such a structure enables workers to inspect, repair, install and other operations on the internal domain control module 121 only through the inspection port 1121 when repairing the domain controller component 100 of the vehicle, thereby effectively avoiding the inconvenience of maintenance due to the scattered installation of the domain control module 121 and the need to dismantle the entire power system 1000 during maintenance, thereby effectively improving the convenience and work efficiency of workers during maintenance.

[0090] In an optional embodiment, the mounting portion 1122 faces the first accommodating cavity 1112a. The inspection port 1121 is connected to the second accommodating cavity 1112b.

[0091] In the embodiment described in the present application, the combined module 124 composed of the DC converter and the on-board charger is installed in the second accommodating chamber 1112b, and the second accommodating chamber 1112b is directly exposed to the inspection port 1121, so the worker can directly inspect the DC converter and the on-board charger through the inspection port 1121. In addition, as described above, the high-voltage distribution unit 125 arranged in the third accommodating chamber 1112c also has a part of its structure exposed to the second accommodating chamber 1112b, so the high-voltage distribution unit 125 can also be inspected and installed directly through the inspection port 1121. Since the motor controller 123 is arranged in the first accommodating chamber 1112a, the worker can first disassemble the cover plate 112 and then inspect the motor controller 123. It can be seen that the structural setting of the shell 110 of the present application not only improves the integration level and space utilization of the domain controller component 100, but also reduces the maintenance difficulty of the domain controller, and improves the convenience and efficiency of workers during inspection, maintenance and installation.

[0092] Of course, in the actual assembly process, according to the actual conditions of different vehicles, vulnerable components can be selectively arranged in the second accommodating cavity 1112b, so as to facilitate workers to inspect them through the inspection port 1121. Therefore, the present application does not impose any restrictions on this.

[0093] In an optional embodiment, the housing 110 further includes a maintenance cover 115. The maintenance cover 115 is detachably disposed on the inspection opening 1121 at a side of the cover plate 112 away from the main body 111.

[0094] When the worker needs to inspect the inside of the housing 110, he only needs to remove the maintenance cover 115 on the outside of the housing 110, and then he can inspect and install the control module 120 through the inspection port 1121. When the worker completes the inspection, he can reinstall the maintenance cover 115 to the inspection port 1121, thereby protecting the components inside the housing 110 and preventing external impurities from entering the housing 110 and affecting the operation of the domain controller.

[0095] In an optional embodiment, if Figure 8 and Fig. 9 As shown, the housing 110 further includes a water inlet pipe 116, a water outlet pipe 117 and a cooling water channel (not shown). The water inlet pipe 116 and the water outlet pipe 117 are connected to the side wall 1111. The cooling water channel is arranged in the accommodating cavity 1112 and connects the water inlet pipe 116 and the water outlet pipe 117.

[0096] Since the domain controller assembly 100 integrates multiple control modules 120 on the housing 110, a relatively high amount of heat is generated inside the housing 110 during operation of the vehicle. However, the present application provides cooling water channels in the housing 110 to effectively cool down each control module 120, thereby avoiding the situation where the temperature inside the housing 110 is too high and affects the working efficiency of the domain controller, and further improving the overall safety of the vehicle.

[0097] As can be seen from the figure, the water inlet of the housing 110 is arranged at the bottom of the first accommodating chamber 1112a, and the water outlet is arranged on the side of the second accommodating chamber 1112b. Therefore, in the actual operation process, the domain controller component 100 will first cool down the motor controller 123, and then cool down the combined module 124 composed of the DC converter and the on-board charger. This setting method conforms to the characteristics of the motor controller 123 generating more heat, and the cooling water channel from bottom to top can also ensure that the coolant performs sufficient heat exchange during the flow process, effectively improving the cooling efficiency and further ensuring the safety of the vehicle and the driver and passengers. In the specific practice process, the bottom of the capacitor 1231 of the motor controller 123 is connected to the first accommodating chamber 1112a through a thermally conductive gel, and the motor controller 123 is also provided with a heat dissipation pin, and the heat dissipation pin is immersed in the cooling water channel, so as to effectively dissipate the heat of the motor controller 123. Similarly, the bottom of the combination module 124 is connected to the second accommodating cavity 1112b through thermal grease, so that the motor controller 123 and the combination module 124 are effectively cooled through the cooling water channel, ensuring the overall safety of the domain controller assembly 100.

[0098] Of course, it should be noted that in other optional embodiments, the arrangement of the cooling water channel can be adjusted accordingly according to the specific structure of the domain controller assembly 100. For example, in an embodiment where the second module generates more heat, the water inlet can be set on the side of the second accommodating cavity 1112b, and the water outlet can be set on the side of the first accommodating cavity 1112a. Therefore, this application does not limit this.

[0099] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
