[0021] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment".

[0023] The embodiments of the present disclosure may involve user data, data acquisition and / or use, etc. These aspects shall comply with the corresponding laws, regulations and relevant provisions. In the embodiments of the present disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user is aware of and confirms them. Accordingly, when implementing the various embodiments of the present disclosure, the types, scope of use, and usage scenarios of the data or information that may be involved should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with the relevant laws and regulations. The specific notification and / or authorization method may vary according to the actual situation and application scenario, and the scope of the present disclosure is not limited in this respect.

[0024] The principles of the present disclosure will be described below with reference to several exemplary embodiments shown in the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way.

[0025] As mentioned earlier, the high vibration environment a vehicle experiences during driving cannot be ignored. Driving, especially on uneven roads, generates severe vibrations. These vibrations are transmitted through the vehicle structure to the domain controller, causing mechanical fatigue, loosening, or even damage to internal electronic components. Furthermore, high-frequency vibrations can cause solder joints on circuit boards to break, further increasing the risk of domain controller failure.

[0026] High temperatures also pose a significant challenge for domain controllers. Autonomous driving, in particular, places higher demands on their computing power. This increased computing power also means consistently high temperatures for electronic components. High temperatures accelerate component aging, shortening their service life. They can also cause unstable performance, drift, and errors, impacting the proper functioning of domain controllers. Furthermore, excessively high temperatures can cause thermal failure, potentially burning out circuit boards and components within the domain controller.

[0027] Furthermore, the impact of high humidity on domain controllers cannot be underestimated. When a vehicle is operating in a humid environment, moisture in the air can gradually penetrate into the domain controller, causing corrosion and short circuits on the circuit boards. Especially in the humid and rainy southern regions, domain controllers are more susceptible to moisture erosion, significantly reducing their reliability and stability.

[0028] Embodiments of the present disclosure provide a housing assembly for a domain controller that addresses, or at least partially addresses, the aforementioned and other potential issues with conventional domain controllers. The domain controller according to the present disclosure utilizes a pair of series-connected water-cooling plates to effectively dissipate heat from its heat-generating components, improving system integration while ensuring stability and reliability. Additional benefits will be described below in conjunction with corresponding embodiments.

[0029] As will be explained below, the domains mentioned in this article refer to vehicle domains. This refers to the functional division of the vehicle's electronic systems into distinct control areas, with each domain responsible for managing a group of related subsystems and components. This division helps simplify the complexity of the vehicle's electrical and electronic architecture (EEA) and improve overall system efficiency and maintainability.

[0030] In a vehicle architecture, each electronic control unit (ECU) is typically responsible for a specific function, such as engine management, braking system, or infotainment system. As the number of vehicle functions increases, this distributed ECU approach results in a large number of separate control units in the system, requiring complex communication and connections between them. In order to facilitate management and maintenance, automakers have begun to adopt the concept of what will be referred to as domain function modules below. A domain function module is a more centralized control unit that integrates multiple related ECUs into a more powerful computing platform. For example, the domain function module 102 may include a power domain function module, a chassis domain function module, a safety domain function module, a cockpit domain function module, an intelligent driving domain function module, a network domain function module, and a multi-domain auxiliary function module, etc.

[0031] The domain controller according to the embodiment of the present disclosure integrates at least two of the above-mentioned domain function modules, thereby further simplifying the complexity of the vehicle's electronic and electrical architecture and improving the overall efficiency and maintainability of the system.

[0032] The following will be combined Figures 1 to 3 To describe the concept according to the embodiment of the present disclosure. Figure 1 A perspective view of a domain controller according to an embodiment of the present disclosure is shown, and Figure 2A and Figure 2B The domain controllers are shown along Figure 1 The cross-sectional view of the plane passing through lines 2A and 2B. Figure 1 、 Figure 2A and Figure 2B As shown, in general, the domain controller according to an embodiment of the present disclosure includes a housing component 101 , at least two domain function modules 102 , and a water cooling component 103 .

[0033] The housing assembly 101 includes a pair of housing units and a pair of internal circulation pipeline avoidance holes 1030. The pair of housing units are stacked and coupled together to form a pair of accommodating spaces, such as Figure 2A and Figure 2B A pair of accommodating spaces are used to accommodate the domain function module 102 and the water cooling component 103. Hereinafter, the pair of accommodating spaces will be referred to as a first accommodating space 1061 and a second accommodating space 1062, respectively.

[0034] At least two domain function modules 102 are arranged in at least one layer of accommodation space and are used to respectively implement domain functions of at least two domains of the vehicle. For example, in some embodiments, the at least two domain function modules 102 can be at least two of the domain function modules mentioned above, that is, the at least two domain function modules 102 include at least two of the following: a power domain function module, a chassis domain function module, a safety domain function module, a cockpit domain function module, an intelligent driving domain function module, a connected domain function module, and a multi-domain auxiliary function module.

[0035] To cope with the high heat generated by the integration of multi-domain functional modules, the water cooling assembly 103 according to the embodiment of the present disclosure is arranged in at least one layer of the storage space. The water cooling assembly 103 includes a pair of water cooling plates 1031 and a heat conduction component 1033. Each water cooling plate 1031 includes a zigzag flow channel 1032, an inlet for coolant to enter the zigzag flow channel 1032, and an outlet for coolant to flow out of the zigzag flow channel 1032.

[0036] The housing assembly of the disclosed embodiment has a pair of internal circulation piping avoidance holes 1030 disposed on the sidewalls of the housing units, respectively, and arranged to correspond to the liquid inlet of the first water-cooling plate and the liquid outlet of the second water-cooling plate, respectively. In this way, the internal circulation piping 105 can be coupled to the liquid inlet of the first water-cooling plate and the liquid outlet of the second water-cooling plate, thereby connecting the coolant in the pair of water-cooling plates in series.

[0037] In some embodiments, the liquid outlet of the first water-cooled plate and the liquid inlet of the second water-cooled plate can also be connected to a pumping element. In this way, the coolant in the zigzag flow channel 1032 can be circulated through the zigzag flow channels 1032 of the two water-cooled plates 1031 by the pumping element. In addition, the zigzag flow channels 1032 between the pair of water-cooled plates 1031 are connected in series via pipes, allowing the coolant to circulate through the zigzag flow channels 1032 of the two cold plates through a single set of pumping elements, reducing the number of components and the difficulty of control, thereby improving assembly efficiency.

[0038] In some embodiments, the first water-cooled plate may be a water-cooled plate in the first accommodating space 1061, and the second water-cooled plate may be a water-cooled plate in the second accommodating space 1062. In such an embodiment, the coolant can enter the water-cooled assembly 103 from the liquid inlet of the second water-cooled plate, and enter the first water-cooled plate from the liquid outlet of the second water-cooled plate, and finally flow into the pumping system from the liquid outlet of the first water-cooled plate to complete the circulation of the coolant. Of course, it should be understood that this method is only schematic, and the positions of the two water-cooled plates can also be interchanged. That is to say, for the entire water-cooled assembly 103, where the liquid enters and where the liquid exits can be exchanged according to actual conditions, and the present disclosure does not impose any restrictions on this.

[0039] According to an embodiment of the present disclosure, the heat-generating components 1021 of at least two domain function modules 102 are respectively arranged on at least one side of a pair of water-cooling plates 1031, and heat-conducting components 1033 are located between the water-cooling plates 1031 and the heat-generating components 1021 (e.g., processors). In this way, the water-cooling plates 1031 can effectively dissipate heat for multiple domain control modules, thereby improving the stability and reliability of the domain controller 100.

[0040] The following will be combined Figure 1 、 Figure 2A and Figure 2B Describe the specific structure of a pair of housing units. For ease of description, the pair of housing units will be referred to as the first housing unit 1063 and the second housing unit 1064, respectively, hereinafter. In some embodiments, the first housing unit 1063 may include a first housing assembly 1011 and a first cover 1012. The first housing assembly 1011 includes a first bottom shell 1066 and a pair of first side walls 1065 extending from the first bottom shell 1066 toward the first side. The first cover 1012 is arranged to be coupled to the pair of first side walls 1065 of the first housing assembly 1011 from the first side to form a first accommodation space 1061 in at least one layer of accommodation space. The first accommodation space 1061 is used to accommodate one of the first water-cooling plates in a pair of water-cooling plates 1031. At the same time, the first accommodation space 1061 also accommodates some domain function modules in at least two domain control modules 102.

[0041] For example, in some embodiments, multiple domain function modules may be arranged on both sides of a first water-cooled plate, and corresponding heat-generating components 1021 may be coupled to the water-cooled plate 1031 via heat-conducting components 1033 for effective heat dissipation and temperature reduction.

[0042] In some embodiments, the second housing unit 1064 includes a second housing assembly 1013 and a second cover 1014. The second housing assembly 1013 includes a second bottom shell 1019 and a pair of second sidewalls 1010 extending from the second bottom shell 1019 toward the second side. The second bottom shell 1019 is coupled to the second side of the first bottom shell 1066.

[0043] like Figure 3 As shown, the second housing assembly 1013 can be formed with a support portion 1020. The support portion 1020 can support the domain controller 100 in a predetermined position when the domain controller 100 is placed horizontally, thereby facilitating the installation and fixing of the domain controller. In this document, when the domain controller 100 is placed horizontally, the first side can represent the upper side, and the second side can represent the lower side. Of course, it should be understood that when the domain controller adopts other installation or fixing orientations, the first side and the second side respectively represent the orientation corresponding to the corresponding orientation, which will not be further described below.

[0044] The second cover 1014 is arranged to couple from the second side to the pair of second sidewalls 1010 of the second housing assembly 1013 to form a second accommodation space 1062. The second accommodation space 1062 is used to accommodate a second water-cooling plate in the pair of water-cooling plates 1031. Similarly to the first accommodation space 1061, the second accommodation space 1062 can also accommodate some domain function modules from at least two domain control modules 102. For example, in some embodiments, multiple domain function modules 102 can be arranged on both sides of the second water-cooling plate, and the corresponding heat-generating components 1021 are coupled to the water-cooling plates 1031 via heat-conducting components 1033 for effective heat dissipation and temperature reduction.

[0045] From the above description, it can be seen that the at least two domain function modules 102 may include a plurality of domain function modules arranged in the first accommodating space 1061 and respectively located on the first side and the second side of the first water-cooling plate; and another plurality of domain function modules arranged in the second accommodating space 1062 and respectively located on the first side and the second side of the second water-cooling plate.

[0046] In some embodiments, the first housing unit 1063 further includes a pair of first auxiliary cover plates 1015. The pair of first auxiliary cover plates 1015 are arranged between the first cover body 1012 and the first bottom shell 1066, and are respectively located between the ends of the pair of first side walls 1065. The pair of first auxiliary cover plates 1015 include a plurality of first clearance holes 1017 through which some of the connection ports in at least two domain function modules 102 pass. These connection ports may include, but are not limited to: Peripheral Component Interconnect Express (PCIe) bus ports, Ethernet ports, diagnostic ports (such as OBD-II), power ports, controller area network bus (CAN) ports, etc. These ports can be connected to corresponding data cables or power cables to connect to external devices or to other domain function modules in the domain controller.

[0047] In some embodiments, the second housing unit 1064 further includes a second auxiliary cover 1016. The second auxiliary cover 1016 is arranged between the second cover body 1014 and the second bottom shell 1019, and is located between the ends of the pair of second side walls 1010, thereby being used to block the opening between the ends of the pair of second side walls 1010. The second auxiliary cover 1016 includes a plurality of second clearance holes 1018 through which some connection ports in at least two domain function modules pass. Similar to the first clearance holes 1017, these ports may include, but are not limited to: a peripheral component interconnect express (PCIe) bus port, an Ethernet port, a diagnostic port (such as OBD-II), a power port, a controller area network bus (CAN) port, etc.

[0048] Furthermore, in some embodiments, at least one of the pair of first sidewalls 1065, at least one of the pair of second sidewalls 1010, and a portion of the first cover 1012 coupled to the pair of first sidewalls 1065 may include a plurality of third clearance holes for passage of some of the connection ports in at least two domain function modules 102. In addition to providing clearance for the plurality of ports mentioned above, the third clearance holes may also include the pair of internal circulation pipeline clearance holes 1030 mentioned above.

[0049] In some embodiments, to improve sealing performance, at least one of a light-curing sealant, a naturally curing sealant, a sealing spacer, and a sealing ring is used to seal the first housing assembly 1011, the first cover 1012, and the pair of first auxiliary cover plates 1015, as well as the second housing assembly 1013, the second cover 1014, and the second auxiliary cover plate 1016. Different sealing methods can be applied to appropriate locations to improve the sealing performance of the entire domain controller and enhance anti-condensation performance, enabling the domain controller to effectively cope with high-humidity environments.

[0050] For example, in some embodiments, the housing assembly may further include a pair of first sealing baffles and a second sealing baffle. The pair of sealing baffles are respectively disposed on the inner sides of the pair of first auxiliary cover plates 1015, and the second sealing baffle is disposed on the inner side of the second auxiliary cover plate 1016. Light-curing sealant, natural-curing sealant, and / or sealing rings may be disposed at other appropriate locations between the first housing assembly 1011 and the first cover body 1012, and between the second housing assembly 1013 and the second cover body 1014 to further improve sealing performance.

[0051] To improve shock absorption performance for at least some of the multiple domain function modules 102, the housing assembly may also include a shock-absorbing component. This component is positioned between at least one of the first housing assembly 1011 and the second housing assembly 1013 and at least two of the domain function modules. The shock-absorbing component may include an elastic component, effectively reducing the risk of damage to the domain function modules caused by the domain controller during vehicle jolting, further improving the reliability of the domain controller.

[0052] Embodiments of the present disclosure also provide a vehicle. The vehicle includes the aforementioned domain controller. By using the domain controller according to embodiments of the present disclosure, the performance and reliability of the vehicle can be improved.

[0053] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, practical applications, or technical improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
