Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an automobile controller assembly and an automobile. Background Technology

[0002] Automotive controllers are typically installed in harsh environments such as the engine compartment, chassis, or exterior of the vehicle body. Therefore, the sealing design of the automotive controller housing is crucial to ensuring its long-term stable and reliable operation.

[0003] Currently, the housing of automotive controllers typically includes a control top cover and a bottom cover that can be mated together. A sealing ring is installed at the mating point of the control top cover and the bottom cover, and the sealing ring is used to provide waterproof and dustproof functions.

[0004] Automotive controllers typically include a circuit board mounted between the upper and lower control covers. To enable connections between external electrical components and the circuit board, the upper and lower control covers usually require sockets for connectors or wiring harnesses of these components to pass through. To ensure the sockets are airtight, a separate sealing ring is required for secondary sealing. However, the stability of these sealing rings is difficult to guarantee; they are prone to twisting or dislodging during long-term vehicle use, leading to seal failure. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive controller assembly and an automotive vehicle to alleviate the technical problem in the prior art where the sealing ring at the socket on the automotive controller housing has poor stability and is prone to twisting or falling off during long-term use of the vehicle, causing sealing failure.

[0006] In a first aspect, the present invention provides an automotive controller assembly, including a housing structure, a circuit board, and a sealing structure; The housing structure includes a control top cover and a control bottom cover, both of which are groove-shaped and interlocked. The groove edges of the control top cover and / or the groove edges of the control bottom cover are provided with recesses. The circuit board is provided with a connector, the circuit board is installed inside the housing structure and the connector passes through the recess and extends out of the housing structure; The sealing structure includes a control ring and a mounting ring. The control ring has a notch, and the mounting ring is fixed to the notch and forms an annular sealing structure with the control ring. The control ring is installed between the groove edge of the control top cover and the groove edge of the control bottom shell, and the mounting ring is installed in the recess and sleeved on the outside of the connector.

[0007] In an optional embodiment, the control bottom shell has a first sealing groove extending circumferentially along its groove edge, and the control top cover has a second sealing groove extending circumferentially along its groove edge. The first sealing groove and the second sealing groove are joined to form a sealing cavity, and the control ring is installed in the sealing cavity.

[0008] In an optional embodiment, a third sealing groove is provided in the recess, and the first sealing groove and / or the second sealing groove communicate with the third sealing groove, and the mounting ring is installed in the third sealing groove.

[0009] In an optional embodiment, a reinforcing part is connected between the control ring and the mounting ring.

[0010] In an optional embodiment, a first positioning post is installed inside the control bottom shell, and a second positioning post is installed inside the control top cover, wherein the first positioning post and the second positioning post abut against each other or are inserted into each other.

[0011] In an optional embodiment, a cooling structure is installed on the control cover.

[0012] In an optional embodiment, the cooling structure includes cooling channels; The control cover includes a control cover plate and a groove-shaped control cover body. The control cover body is connected to the control bottom shell, and the control cover plate is fixed to the side of the control cover body that is opposite to the control bottom shell. The control cover plate has a cooling groove on the side facing the control cover body and / or the control cover body has a cooling groove on the side facing the control cover plate. The cooling groove is used to form a cooling channel between the control cover plate and the control cover body, and a cooling medium is introduced into the cooling channel.

[0013] In an optional embodiment, the cooling channel has multiple bends along its length to allow it to bend and coil around the control cover.

[0014] In an optional embodiment, the side of the control cover plate facing the control cover body and the side of the control cover body facing the control cover plate are respectively provided with cooling grooves, and the cooling grooves on the control cover plate and the cooling grooves on the control cover body are connected to form the cooling channel. The control cover is provided with a liquid inlet connected to one end of the cooling channel and a liquid outlet connected to the other end of the cooling channel. The liquid inlet and the liquid outlet are respectively used to connect to an external liquid supply device.

[0015] In a second aspect, the present invention provides an automobile, including the automobile controller assembly described in any of the foregoing embodiments.

[0016] The automotive controller assembly provided by this invention includes a housing structure, a circuit board, and a sealing structure. The housing structure includes a control top cover and a control bottom cover, both grooved and interlocking. The groove edges of the control top cover and / or the control bottom cover have recessed portions. The circuit board has a connector, which is installed inside the housing structure, with the connector passing through the recessed portion and extending outside the housing structure. The sealing structure includes a control ring and a mounting ring. The control ring has a notch, and the mounting ring is fixed to the notch, forming a ring-shaped sealing structure with the control ring. The control ring is installed between the groove edges of the control top cover and the control bottom cover, and the mounting ring is installed in the recessed portion and sleeved over the connector. The automotive controller assembly provided by this invention is applied to automobiles and can be installed in harsh environments such as the engine compartment, chassis, or exterior of the vehicle body. During the assembly of this automotive controller assembly, the annular sealing structure formed by the fixed connection of the control ring and the mounting ring can first be installed on the edge of the groove of the control cover or the control bottom shell, with the mounting ring positioned in the recessed area. Then, the circuit board is installed inside the control cover or control bottom shell, with the connector on the circuit board passing through the mounting ring and extending out of the shell structure. Next, the edge of the groove of the control cover is aligned with the edge of the groove of the control bottom shell, thus fixing the control cover and control bottom shell together to form the shell structure. At this point, the annular sealing structure between the groove edges of the control cover and the control bottom shell effectively seals the gaps between the control cover and the control bottom shell, as well as the gaps between the recessed area of ​​the shell structure and the connector, thereby effectively ensuring the overall sealing performance of the shell structure. Simultaneously, since the annular surface sealing structure is formed by the fixed connection of the control ring and the mounting ring, the control ring can also support and fix the mounting ring, effectively improving the installation stability of the mounting ring (i.e., the sealing structure at the connector) and preventing the sealing structure at the connector from twisting or detaching during long-term vehicle use.

[0017] Compared with the prior art, the automotive controller assembly provided by the present invention extends the connector of the circuit board outside the housing structure and uses the control ring and the mounting ring to form an annular sealing structure to seal the gap between the control top cover and the control bottom shell, as well as the gap between the housing structure and the connector. This can effectively improve the installation stability of the sealing structure at the connector while ensuring the sealing performance of the housing structure, and prevent the mounting ring from twisting or falling off during long-term use of the vehicle, thereby effectively improving the sealing effect of the sealing structure.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Example: like Figure 1 , Figure 2 and Figure 3 As shown, the vehicle controller assembly provided in this embodiment includes a housing structure 1, a circuit board 2, and a sealing structure 3. The housing structure 1 includes a control top cover 10 and a control bottom cover 11, both of which are groove-shaped and interlocked. The groove edge of the control top cover 10 or the groove edge of the control bottom cover 11 is provided with a recess 12, or both the groove edge of the control top cover 10 and the groove edge of the control bottom cover 11 are provided with recesses 12. The circuit board 2 is provided with a connector 20. The circuit board 2 is installed inside the housing structure 1, and the connector 20 passes through the recess 12 and extends out of the housing structure 1. The sealing structure 3 includes a control ring 30 and a mounting ring 31. The control ring 30 is provided with a notch, and the mounting ring 31 is fixed at the notch and forms an annular sealing structure 3 with the control ring 30. The control ring 30 is installed between the groove edge of the control top cover 10 and the groove edge of the control bottom cover 11, and the mounting ring 31 is installed at the recess 12 and sleeved on the connector 20.

[0029] The vehicle controller assembly provided in this embodiment serves as a control system for a vehicle and can be applied to a vehicle. The vehicle controller assembly can be installed in harsh environments such as the engine compartment, chassis, or exterior of the vehicle body.

[0030] like Figure 2 and Figure 3 As shown, during the assembly of the automotive controller assembly, the annular sealing structure 3 formed by the fixed connection of the control ring 30 and the mounting ring 31 can first be installed on the edge of the slot of the control cover 10 or the edge of the slot of the control bottom shell 11, with the mounting ring 31 located at the recess 12 on the edge of the slot of the control cover 10 or the slot of the control bottom shell 11. Then, the circuit board 2 is installed inside the control cover 10 or the control bottom shell 11, with the connector 20 on the circuit board 2 passing through the mounting ring 31 and extending out of the housing structure 1. The electronic components of the automotive controller assembly are integrated on the circuit board 2. Then, as... Figure 1 As shown, the groove edge of the control cover 10 is aligned with the groove edge of the control bottom shell 11. If both the groove edge of the control cover 10 and the groove edge of the control bottom shell 11 are provided with recessed portions 12, then the recessed portion 12 of the groove edge of the control cover 10 and the recessed portion 12 of the groove edge of the control bottom shell 11 can be aligned to form a through hole for the connector 20 to pass through.

[0031] When aligning the groove edge of the control cover 10 with the groove edge of the control base 11, the control cover 10 and the control base 11 must be fixedly connected to form the housing structure 1. The fixing method can include bolt connection, snap-fit, or adhesive bonding. At this time, the annular sealing structure 3 between the groove edge of the control cover 10 and the groove edge of the control base 11 can effectively seal the gap between the control cover 10 and the control base 11, and the gap between the recessed portion 12 of the housing structure 1 and the connector 20, thereby effectively ensuring the overall sealing performance of the housing structure 1. Simultaneously, since the annular sealing structure 3 is formed by the fixed connection of the control ring 30 and the mounting ring 31, that is, the annular sealing structure 3 adopts an integrated design of the control ring 30 and the mounting ring 31, the control ring 30 can also support and fix the mounting ring 31, effectively improving the installation stability of the mounting ring 31 (i.e., the sealing structure 3 at the connector 20) and preventing the sealing structure 3 at the connector 20 from twisting or falling off during long-term vehicle use.

[0032] Compared with the prior art, the vehicle controller assembly provided in this embodiment extends the connector 20 of the circuit board 2 outside the housing structure 1, and uses the control ring 30 and the mounting ring 31 to form an annular sealing structure 3 to seal the gap between the control cover 10 and the control bottom shell 11, as well as the gap between the housing structure 1 and the connector 20. This can effectively improve the installation stability of the sealing structure 3 at the connector 20 while ensuring the sealing performance of the housing structure 1, and prevent the mounting ring 31 from twisting or falling off during long-term use of the vehicle, thereby effectively improving the sealing effect of the sealing structure 3.

[0033] It should be noted that, compared with the existing technology of opening holes on the car controller housing for connectors or wiring harnesses of external electrical components to pass through and hiding the entire circuit board 2 of the car controller inside the housing, the car controller assembly provided in this embodiment provides a more flexible external connection method for the circuit board 2 by setting recesses 12 on the edge of the slot of the control cover 10 and / or the edge of the slot of the control bottom shell 11, and using the recesses 12 to allow the connector 20 of the circuit board 2 to extend out of the housing structure 1. This avoids the wiring difficulties caused by improper interface positions in the prior art and achieves a compact design with high integration.

[0034] like Figure 2 and Figure 3 As shown, there can be multiple connectors 20, and correspondingly, there are multiple recesses 12, notches, and mounting rings 31. At this time, multiple mounting rings 31 are fixed one-to-one with multiple notches on the control ring 30, and the multiple mounting rings 31 and the control ring 30 are combined to form an annular sealing structure 3.

[0035] As can be seen, when there are multiple connectors 20, compared with the prior art which requires multiple independent sealing rings to be set at multiple sockets on the car controller housing for secondary sealing, in this embodiment, multiple mounting rings 31 are all fixed on the control ring 30. This not only makes the overall structure of the sealing structure 3 more concentrated and orderly, but also effectively ensures the structural stability of the sealing structure 3 at multiple connectors 20, thereby effectively improving the overall sealing effect of the sealing structure 3.

[0036] In one embodiment, such as Figure 2 and Figure 3 As shown, the control bottom shell 11 has a first sealing groove 110 extending circumferentially at the edge of its groove, and the control top cover 10 has a second sealing groove 100 extending circumferentially at the edge of its groove. The first sealing groove 110 and the second sealing groove 100 are joined to form a sealing cavity, and the control ring 30 is installed in the sealing cavity.

[0037] By opening a first annular sealing groove 110 extending circumferentially along the edge of the groove in the control bottom shell 11, and opening a second annular sealing groove 100 extending circumferentially along the edge of the groove in the control top cover 10, and using the first sealing groove 110 and the second sealing groove 100 to form a complete annular sealing cavity, the control ring body 30 of the sealing structure 3 can be wrapped. Thus, the sealing method of opening grooves on both sides of the control top cover 10 and the control bottom shell 11 effectively improves the installation stability of the sealing structure 3 between the control top cover 10 and the control bottom shell 11, so that the control ring body 30 is subjected to uniform force during installation, is not easy to twist or fall off, and effectively prevents moisture and dust from seeping into the joint between the control top cover 10 and the control bottom shell 11 of the shell structure 1.

[0038] Furthermore, the diameter of the radial section of the control ring 30 can be larger than the diameter of the radial section of the sealing cavity. Thus, the control ring 30 can be interference-fitted into the sealed cavity. When the control cover 10 and the control bottom shell 11 are connected by fasteners such as bolts, the control ring 30 will be squeezed in the sealing cavity and generate elastic deformation, thereby tightly filling the internal space of the sealing cavity and forming an interference fit with the inner wall of the first sealing groove 110 and the inner wall of the second sealing groove 100. This effectively blocks the path of external moisture and dust from entering the sealing cavity through the joint between the control cover 10 and the control bottom shell 11 of the housing structure 1.

[0039] In one embodiment, a third sealing groove 120 is provided in the recess 12, and the first sealing groove 110 or the second sealing groove 100 is connected to the third sealing groove 120, or the first sealing groove 110 and the second sealing groove 100 are respectively connected to the third sealing groove 120, and the mounting ring 31 is installed in the third sealing groove 120.

[0040] The third sealing groove 120 is used to accommodate the mounting ring 31. When both the groove edge of the control cover 10 and the groove edge of the control bottom shell 11 are provided with recesses 12, the recesses 12 of the groove edge of the control cover 10 and the recesses 12 of the groove edge of the control bottom shell 11 can also be connected to form a sealed cavity to accommodate the mounting ring 31. The first sealing groove 110 and the second sealing groove 100 are connected to form a sealing cavity, which together with the sealed cavity forms a continuous closed cavity. At this time, the annular sealing structure 3 can be completely accommodated in the continuous closed cavity formed by the sealing cavity and the sealed cavity. This can effectively avoid the problem of displacement or local wear of the sealing structure 3 due to long-term vibration, and further improve the reliability of the long-term operation of the automotive controller assembly.

[0041] like Figure 3 As shown, a reinforcing part 32 connects the control ring 30 and the mounting ring 31.

[0042] By providing a reinforcing part 32 between the control ring 30 and the mounting ring 31, the structural strength of the mounting ring 31 and the sealing structure 3 can be increased, further improving the long-term reliability of the automotive controller assembly.

[0043] The shape of the reinforcing part 32 is not limited and can be selected according to actual needs. For example, the reinforcing part 32 can adopt a triangular structure.

[0044] In one embodiment, such as Figure 2 As shown, a first positioning post 111 is installed inside the control bottom shell 11, and a second positioning post 101 is installed inside the control top cover 10. The first positioning post 111 and the second positioning post 101 abut against each other or are inserted into each other.

[0045] During the assembly of the vehicle controller assembly in this embodiment, when the control base 11 is docked with the control top cover 10, the first positioning post 111 and the second positioning post 101 abut against or insert into each other. At this time, the first positioning post 111 and the second positioning post 101 can cooperate to provide auxiliary guidance for the docking process between the control base 11 and the control top cover 10, thereby improving the smoothness of the installation of the control base 11 and the control top cover 10. At the same time, the first positioning post 111 and the second positioning post 101 can also improve the docking stability between the control top cover 10 and the control base 11, thereby improving the overall structural stability of the housing structure 1.

[0046] It should be noted that since the first positioning post 111 is installed inside the control bottom shell 11 and the second positioning post 101 is installed inside the control top cover 10, the first positioning post 111 and the second positioning post 101 make full use of the internal space of the control bottom shell 11 and the control top cover 10, that is, make full use of the internal space of the shell structure 1, and will not affect the overall volume of the shell structure 1.

[0047] There are no restrictions on the number or specific installation location of the first positioning post 111 and the second positioning post 101; they can be selected according to actual needs. For example, ... Figure 2 As shown, both the control cover 10 and the control bottom shell 11 are rectangular in shape. There are four first positioning posts 111 and four second positioning posts 101. The four first positioning posts 111 are installed one-to-one at the four corners of the control bottom shell 11, and correspondingly, the four second positioning posts 101 are installed one-to-one at the four corners of the control cover 10.

[0048] In one embodiment, the control base 11 may have an abutment portion inside, which abuts against the edge of the circuit board 2 to limit the installation position of the circuit board 2 inside the control base 11 and prevent the circuit board 2 from shifting position inside the control base 11.

[0049] It can be seen that the abutment part can limit the circuit board 2. It can not only provide guidance and positioning for the installation process of the circuit board 2 during the assembly process, so that the installation and positioning of the circuit board 2 is fast and accurate, but also prevent the circuit board 2 from shifting after it is installed and fixed. It provides precise positioning and reliable support for the circuit board 2, which helps to make the heat dissipation path of the circuit board 2 shorter and the heat conduction efficiency higher, thereby ensuring that the automotive controller components can operate stably for a long time in harsh temperature environments.

[0050] The number and structure of the abutment are not limited and can be selected according to actual needs. For example, the abutment can be a protrusion and there are multiple abutments, which are distributed at intervals along the circumference of the circuit board 2 inside the control bottom shell 11. Alternatively, the abutment can be an annular baffle and fixed inside the control bottom shell 11, with the circumferential edge of the circuit board 2 abutting against the inner circumferential wall of the abutment.

[0051] In one embodiment, such as Figure 1 and Figure 2 As shown, a cooling structure 4 is installed on the control cover 10.

[0052] The heat generated by the circuit board 2 during operation can be conducted to the cooling structure 4 through the control cover 10, and then the heat is carried away by the heat exchange of the cooling structure 4, effectively ensuring the long-term stable operation of the automotive controller components in harsh temperature environments.

[0053] As can be seen, the automotive controller assembly provided in this embodiment can dissipate heat from the circuit board 2 through the combination of the control cover 10 of the housing structure 1 and the cooling structure 4, thus ensuring the service life of the automotive controller assembly under harsh temperature environments.

[0054] The control cover 10 and the cooling structure 4 can be detachably connected or integrally formed. When the control cover 10 and the cooling structure 4 are integrally formed, not only can the volume of the vehicle controller assembly be increased without adding extra volume, but the structural strength of the housing structure 1 of the vehicle controller assembly can also be effectively improved.

[0055] When the control cover 10 and the cooling structure 4 are integrally formed, such as Figure 1 and Figure 2 As shown, the cooling structure 4 includes a cooling channel; the control cover 10 includes a control cover plate 102 and a grooved control cover body 103, the control cover body 103 is connected to the control bottom shell 11, and the control cover plate 102 is fixed to the side of the control cover body 103 facing away from the control bottom shell 11; a cooling groove 40 is provided on the side of the control cover plate 102 facing the control cover body 103 or the side of the control cover body 103 facing the control cover plate 102, or both the side of the control cover plate 102 facing the control cover body 103 and the side of the control cover body 103 facing the control cover plate 102 are provided with cooling grooves 40, the cooling grooves 40 are used to form a cooling channel between the control cover plate 102 and the control cover body 103, and a cooling medium is introduced into the cooling channel.

[0056] The cooling medium can be a cooling liquid such as water. During the heat dissipation process, the heat at the circuit board 2 can be transferred to the control cover 10. Then, the heat on the control cover 10 can exchange heat with the cooling medium in the cooling channel and be carried away by the cooling ring, thereby achieving heat dissipation of the circuit board 2.

[0057] To improve heat dissipation efficiency and effect, the cooling channel can be connected to an external liquid supply device, which provides flowing cooling medium, thereby continuously introducing a low-temperature cooling medium into the cooling channel.

[0058] As can be seen, providing cooling grooves 40 on the control cover 102 or control cover 103 not only creates cooling channels within the control cover 10 to dissipate heat from the circuit board 2, but also eliminates the need to add a cooling structure 4 outside the control cover 10, thus reducing the size of the automotive controller assembly and achieving a compact design with high integration. Furthermore, providing cooling grooves 40 on the control cover 102 or control cover 103 allows the cooling channels to be tightly attached to the circuit board 2 within the housing structure 1, forming a close-fitting cooling structure 4. This close-fitting cooling structure 4 has a short heat dissipation path and low thermal resistance, effectively improving the heat dissipation efficiency and effect, further ensuring the long-term stable operation of the automotive controller assembly under harsh temperature environments.

[0059] like Figure 1 and Figure 2 As shown, along the length of the cooling channel, there are multiple bends in the cooling channel so that the cooling channel is bent and coiled on the control cover 10.

[0060] When the cooling channel is bent and coiled on the control cover 10, the length of the cooling channel can be effectively increased, thereby improving the heat dissipation area and heat dissipation effect.

[0061] The direction of the cooling channel's bending and coiling can be regular or irregular; for example, the cooling channel can be a continuous S-shaped bend.

[0062] In this embodiment, as Figure 2 As shown, cooling grooves 40 are respectively provided on the side of the control cover plate 102 facing the control cover body 103 and the side of the control cover body 103 facing the control cover plate 102, and the cooling grooves 40 on the control cover plate 102 and the cooling grooves 40 on the control cover body 103 are connected to form a cooling channel; the control cover 10 is provided with a liquid inlet 41 connected to one end of the cooling channel and a liquid outlet 42 connected to the other end of the cooling channel, and the liquid inlet 41 and the liquid outlet 42 are respectively used to connect to an external liquid supply device.

[0063] The cooling grooves 40 on the control cover 102 and the control cover 103 cooperate to form a cooling channel. This not only guides the cooling medium but also increases the volume of the cooling channel, allowing it to hold more cooling medium. This ensures sufficient contact between the heat-generating element area inside the housing structure 1 and the control cover 10, resulting in a shorter heat dissipation path and higher heat transfer efficiency. This further guarantees the long-term stable operation of the automotive controller components in harsh temperature environments.

[0064] In one embodiment, both the liquid inlet 41 and the liquid outlet 42 are disposed on the control cover plate 102, and the liquid inlet 41 and the liquid outlet 42 are respectively connected to the cooling groove 40 on the control cover plate 102. Compared with disposing both the liquid inlet 41 and the liquid outlet 42 on the control cover body 103, disposing both the liquid inlet 41 and the liquid outlet 42 on the control cover plate 102 can effectively improve the convenience of connection and disassembly between the cooling structure 4 and the external liquid supply device.

[0065] Furthermore, such as Figure 2 As shown, a support ring 43 is fixed at the position corresponding to the liquid inlet 41 and the liquid outlet 42 of the control cover plate 102. The support ring 43 at the liquid inlet 41 is connected to the liquid inlet 41 and fixedly connected to the control cover plate 102. The support ring 43 at the liquid outlet 42 is connected to the liquid outlet 42 and fixedly connected to the control cover plate 102.

[0066] The support ring 43 is used to increase the strength of the control cover plate 102 around the liquid inlet 41 and to increase the strength of the control cover plate 102 around the liquid outlet 42.

[0067] Furthermore, such as Figure 2 As shown, cooling connecting pipes 44 are respectively inserted and fixed in the support ring 43 at the liquid inlet 41 and the support ring 43 at the liquid outlet 42. One end of the cooling connecting pipe 44 in the support ring 43 at the liquid inlet 41 passes through the liquid inlet 41 and communicates with the cooling groove 40 on the control cover plate 102. The other end is located on the side of the control cover plate 102 opposite to the control cover body 103 and communicates with the external liquid supply device. One end of the cooling connecting pipe 44 in the support ring 43 at the liquid outlet 42 passes through the liquid outlet 42 and communicates with the cooling groove 40 on the control cover plate 102. The other end is located on the side of the control cover plate 102 opposite to the control cover body 103 and communicates with the external liquid supply device.

[0068] It can be seen that the support ring 43 can provide a stable mounting base and reinforced support for the cooling connection pipe 44, effectively dispersing the mechanical stress at the pipe connection between the control cover plate 102 and the external liquid supply device, preventing the pipe connection from loosening or the control cover plate 102 from being damaged due to vehicle vibration, pipe insertion and removal or cooling medium impact, and significantly improving the long-term working reliability of the cooling system (including the cooling structure 4 and the external liquid supply device) in harsh vehicle environments.

[0069] There are no restrictions on the installation method of the cooling connection pipe 44 inside the support ring 43. It can be selected according to actual needs. For example, the cooling connection pipe 44 can be fixed inside the support ring 43 by welding.

[0070] In summary, the automotive controller assembly provided in this embodiment achieves a double-sided slotted sealing method on the control cover 10 and control bottom housing 11 by opening a first sealing groove 110 at the edge of the groove and a second sealing groove 100 at the edge of the groove, with the first sealing groove 110 and the second sealing groove 100 joined together to form a sealed cavity. The control ring 30 of the sealing structure 3 is then completely enclosed within the sealed cavity. This ensures that the control ring 30 of the sealing structure 3 is evenly stressed during installation, preventing twisting or detachment, and effectively preventing moisture and dust from penetrating from the joint between the control cover 10 and the control bottom housing 11 of the housing structure 1. Furthermore, the automotive controller assembly provided in this embodiment integrates the cooling structure 4 onto the control cover 10, allowing the heat generated by the circuit board 2 during operation to be conducted through the control cover 10 to the cooling channel of the cooling structure 4, and then carried away by the cooling medium flowing through the cooling channel. This close-fitting cooling structure 4 has a short heat dissipation path and low thermal resistance, ensuring that the automotive controller assembly can operate stably for a long time in harsh temperature environments. Meanwhile, the vehicle controller assembly provided in this embodiment, through the cooperation of the cooling groove 40 on the control cover 102 and the cooling groove 40 on the control cover 103, not only guides the cooling medium, but also allows the cooling channel to accommodate more cooling medium, ensuring full contact between the heat-generating element area inside the housing structure 1 and the cooling structure 4, making the heat dissipation path of the cooling structure 4 shorter and the heat conduction efficiency higher, further effectively ensuring the long-term stable operation of the vehicle controller assembly under harsh temperature environments.

[0071] This embodiment also provides a car that includes the above-mentioned car controller assembly. Therefore, the car provided in this embodiment can also extend the connector 20 of the circuit board 2 outside the housing structure 1, and use the control ring 30 and the mounting ring 31 to form an annular sealing structure 3 to seal the gap between the control cover 10 and the control bottom shell 11, as well as the gap between the housing structure 1 and the connector 20. This effectively improves the installation stability of the sealing structure 3 at the connector 20 while ensuring the sealing performance of the housing structure 1, and prevents the mounting ring 31 from twisting or falling off during long-term use of the vehicle, thereby effectively improving the sealing effect of the sealing structure 3.

[0072] When a cooling structure 4 is installed on the control cover 10 in the vehicle controller assembly, and the cooling structure 4 includes a cooling channel, a cooling groove 40 is provided on the side of the control cover 102 facing the control cover body 103 or on the side of the control cover body 103 facing the control cover 102, or both the side of the control cover 102 facing the control cover body 103 and the side of the control cover body 103 facing the control cover 102 are provided with cooling grooves 40, and the cooling groove 40 forms a cooling channel between the control cover 102 and the control cover body 103, the vehicle provided in this embodiment may also include a liquid supply device for supplying cooling medium into the cooling channel.

[0073] Furthermore, when the control cover 10 is provided with an inlet 41 and an outlet 42, and both the inlet 41 and the outlet 42 are located on the control cover plate 102, the inlet 41 and the outlet 42 are respectively connected to the cooling groove 40 on the control cover plate 102, a support ring 43 is fixed at the position corresponding to the inlet 41 and the outlet 42 on the control cover plate 102, and a cooling connecting pipe 44 is inserted and fixed in the support ring 43 at the inlet 41 and the support ring 43 at the outlet 42, the liquid supply device may include a liquid supply connector 20, a liquid return connector 20, a liquid supply pipeline, a liquid return pipeline, a cooling medium container, and a pump body.

[0074] The cooling medium container has a supply port and a return port. A supply connector 20 is fixed and connected to one end of the supply pipeline, and the other end of the supply pipeline is connected to the supply port of the cooling medium container. A return connector 20 is fixed and connected to one end of the return pipeline, and the other end of the return pipeline is connected to the return port of the cooling medium container. The pump body is installed on either the supply pipeline or the return pipeline. The supply connector 20 is inserted into and fixedly connected to the cooling connecting pipe 44 inside the support ring 43 at the inlet 41. The return connector 20 is inserted into and fixedly connected to the cooling connecting pipe 44 inside the support ring 43 at the outlet 42.

[0075] When the pump is turned on, the pump can drive the cooling medium in the cooling medium container to flow sequentially through the liquid supply pipeline, the liquid supply connector 20 and the cooling connection pipe 44 in the support ring 43 at the liquid inlet 41 on the control cover 102 to the cooling channel in the control cover 10. Then, it exchanges heat with the heat generation element area inside the housing structure 1. After the heat exchange, the cooling medium is heated. Then, the heated cooling medium will flow back to the cooling medium container through the cooling connection pipe 44 in the support ring 43 at the liquid outlet 42 on the control cover 102, the return connector 20 and the return pipeline, thereby realizing the circulation of the cooling medium between the liquid supply device and the cooling structure 4.

[0076] Furthermore, a cooling device can be installed at the cooling medium container or on the return pipe. The cooling device can be a compressor. The cooling device is used to cool the cooling medium flowing back into the cooling medium container, so that the cooling medium entering the supply pipe is always a low-temperature cooling medium to ensure the heat dissipation effect of the cooling structure 4.
