[0002] Vehicle control units are core components for achieving automotive intelligence, responsible for integrating sensor data and executing complex control algorithms. With the continuous advancement of automotive electronic systems, control unit functionality has become increasingly complex, leading to a gradual increase in the electromagnetic wave intensity of control unit chips, and therefore, a corresponding increase in the requirements for electromagnetic shielding performance.

[0003] In related technologies, brazing is often used to connect the stamped water-cooling plate to the die-cast midframe to improve the heat dissipation performance of the control device housing. Specifically, structural adhesive is typically applied between the stamped water-cooling plate and the die-cast midframe to achieve a stable connection. However, tiny particles in the adhesive can create tiny gaps between the two. Due to the adhesive's non-conductivity, these tiny gaps can affect the housing's electromagnetic shielding, reducing its ability to shield against external electromagnetic interference and, consequently, impacting the performance of the power module within the control device.

[0004] In view of this, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0033] Vehicle control units are core components for achieving automotive intelligence, responsible for integrating sensor data and executing complex control algorithms. With the continuous advancement of automotive electronic systems, control unit functionality has become increasingly complex, leading to a gradual increase in the electromagnetic wave intensity of control unit chips, and therefore, a corresponding increase in the requirements for electromagnetic shielding performance.

[0034] To improve the heat dissipation of the control device, the cooling module (such as a stamped water-cooled plate) is typically brazed to the die-cast midframe, with structural adhesive placed between the two to stabilize the connection. However, structural adhesive often contains tiny particles, which can easily lead to gaps between the cooling module and the die-cast midframe. Furthermore, since structural adhesive is generally non-conductive, these gaps can affect the electromagnetic shielding function of the housing.

[0035] For example, the power module, including the circuit boards and electronic components within the control unit, generates electromagnetic noise signals that can radiate externally through tiny gaps in the housing. Simultaneously, external electromagnetic noise can enter the control unit through these gaps. This bidirectional electromagnetic interference can distort or interfere with the power module's signals, affecting its normal operation and degrading its performance and reliability. More seriously, this interference can affect the functionality and stability of the entire control unit and lead to instability or failure of the vehicle's electronic systems.

[0036] Please refer to Figure 1-2 , is a schematic diagram of a control device according to an embodiment of the present application. The control device can solve the problem of poor electromagnetic shielding performance caused by gaps in the prior art due to tiny particles of structural adhesive.

[0037] Specifically, the control device provided in this embodiment includes a first housing 11 and a second housing 14, which are tightly connected by snapping together to form a closed housing cavity for accommodating the power module 2, including the circuit board and electronic components of the control device.

[0038] In order to enhance the structural strength and electromagnetic shielding performance of the control device, the first shell 11 and the second shell 14 are both made of conductive materials.

[0039] refer to Figure 1 and 2 Furthermore, a cooling module 12 is interposed between the first housing 11 and the second housing 14 to improve the heat dissipation performance of the control device. The cooling module 12 includes a cooling body 121 and an extension 122 connected to the cooling body 121. The cooling body 121 is disposed within the accommodating cavity, while the extension 122 is disposed outside the accommodating cavity. The upper and lower surfaces of the extension 122 are connected to the second housing 14 and the first housing 11, respectively.

[0040] The cooling body 121 divides the housing cavity into two independent chambers, namely a first chamber 101 and a second chamber 102. The first chamber 101 and the second chamber 102 are respectively used to accommodate different power modules 2. This not only effectively improves the heat dissipation effect of the power modules 2, but also reduces the thermal interference caused by the heat generated by a single power module 2 during operation on other power modules 2.

[0041] Furthermore, a cooling pipe is provided on the cooling body 121, and the cooling pipe is also connected to a water inlet pipe 123 and a drain pipe 124 to ensure efficient circulation of the coolant. Figure 1 The water inlet pipe 123 and the drain pipe 124 are both protruding from the upper surface of the extension portion 122 to facilitate installation and maintenance.

[0042] Furthermore, the extension portion 122 of the cooling module 12 is also made of metal material and is tightly connected to the first shell 11 through brazing technology, and an insulating adhesive layer is coated between the extension portion 122 and the first shell 11 to strengthen fixation.

[0043] As described above, the tiny particles in the insulating adhesive layer cause a gap in the connection between the first shell 11 and the extension portion 122 . The gap will cause discontinuity in electrical conduction, affecting the electromagnetic shielding performance of the control device.

[0044] Therefore, to reduce the impact of gaps on electromagnetic shielding performance, in this embodiment, a conductive connector 13 (such as a conductive metal block) is further provided between the extension 122 of the cooling module 12 and the first housing 11. One end of the connector 13 is connected to the extension 122, and the other end is connected to the first housing 11, thereby further establishing an electrical connection between the first housing 11 and the cooling module 12, improving the continuity of electrical conduction, thereby effectively conducting electromagnetic waves, reducing electromagnetic wave leakage in the gap, and thereby enhancing the electromagnetic shielding effectiveness of the overall control device structure.

[0045] In one embodiment, the connecting member 13 is a conductive block.

[0046] Specifically, the conductive block is typically made of a highly conductive material (such as copper, aluminum, or silver) with excellent electrical conductivity. This high conductivity ensures that the connector 13 can provide effective electrical continuity, reduce electrical discontinuities, and thus significantly improve electromagnetic shielding effectiveness.

[0047] In another embodiment, the connecting member 13 is a conductive rubber block.

[0048] Conductive adhesive blocks are solid adhesives made from conductive adhesive materials. Their primary characteristic is their ability to provide a conductive path after curing. Conductive adhesive materials typically contain conductive fillers (such as silver powder, copper powder, or carbon black), which enable the conductive adhesive block to form effective electrical continuity when connecting two conductive surfaces.

[0049] Furthermore, the use of conductive adhesive for connector 13 offers other advantages. For example, conductive adhesive possesses excellent adhesion properties, allowing it to firmly adhere to the surfaces of various materials, forming a stable connection. This adhesion ensures that the conductive adhesive will not fall off or shift during long-term use, maintaining a stable conductive connection between two conductive members (e.g., extension portion 122 and first housing 11).

[0050] For example, conductive adhesive can fill tiny gaps in joints or uneven surfaces, forming a seamless conductive path. This filling ability reduces the possibility of electromagnetic waves leaking through gaps, thereby improving the overall shielding effectiveness of the control device.

[0051] In one embodiment, a receiving groove 100 is further defined on the surface of the first shell 11 facing the extension portion 122 , and the first shell 11 and the extension portion 122 press and secure the connector 13 in the receiving groove 100 .

[0052] First, the structural design of the accommodating groove 100 helps to improve the stability and reliability of the connection of the connector 13, so that it remains stable under various environmental conditions, thereby forming a stable conductive path between the first shell 11 and the extension portion 122, reducing conductivity discontinuity, and improving the overall shielding effectiveness of the control device.

[0053] Secondly, the structure of the receiving groove 100 facilitates close contact between the connector 13 and the first housing 11 and the extension portion 122 , thereby helping to provide effective electrical continuity and reduce electromagnetic wave leakage.

[0054] In addition, the design of the receiving groove 100 also helps to simplify the installation process of the connector 13, reducing installation time and complexity.

[0055] Similarly, in another embodiment, a receiving groove 100 is provided on the extension portion 122 of the cooling module 12, and the first shell 11 and the extension portion 122 press and fix the connecting member 13 in the receiving groove 100. The connection method and effect are similar to those of providing the receiving groove 100 on the first shell 11, and will not be repeated here.

[0056] Of course, in one feasible embodiment, grooves are formed on both the first housing 11 and the extension 122, and these two grooves together form the aforementioned receiving groove 100. The connector 13 is placed in the receiving groove 100 formed by these two grooves, and then the connector 13 is fixed by pressing the first housing 11 and the extension 122 together, ensuring that the connector 13 is stably positioned in the receiving groove 100.

[0057] This fixing method can further enhance the close contact between the connector 13 and the first shell 11 and the extension portion 122, thereby improving the stability and reliability of the connection between the connector 13 and the two, thereby forming a stable conductive path between the two, reducing conductivity discontinuity, and reducing electromagnetic wave leakage.

[0058] In one embodiment, the cross section of the receiving groove 100 is rectangular, that is, the receiving groove 100 is a rectangular groove.

[0059] In another embodiment, the cross section of the receiving groove 100 is cross-shaped. The cross-shaped receiving groove 100 structure helps to increase the contact area between the connecting member 13 and the first housing 11 and the extension portion 122, thereby improving the stability and reliability of the connection.

[0060] In one embodiment, the connector 13 is disposed close to the water inlet pipe 123 or the drain pipe 124 to more effectively reduce the problem of electromagnetic wave leakage.

[0061] Specifically, when the water inlet pipe 123 or the drain pipe 124 is protruding, they can be regarded as antenna-like structures at certain frequencies, which can pull and amplify electromagnetic waves, making it easy for electromagnetic waves to gather in these areas.

[0062] Since the electromagnetic wave energy near the antenna effect area is relatively strong, if there are gaps at the connection between the extension portion 122 and the first shell 11 due to the presence of particles in the insulating rubber layer, these gaps will aggravate the electrical discontinuity between the cooling module 12 and the second shell 14, making the leakage of electromagnetic waves between the two more serious.

[0063] Therefore, placing the connector 13 close to the water inlet pipe 123 and the drain pipe 124 helps to reduce and eliminate the electromagnetic wave leakage problem in this area.

[0064] In a feasible implementation, a grounding terminal is further provided on the first housing 11 .

[0065] Specifically, when external electromagnetic waves encounter a grounded metal shell, most of them are reflected or absorbed and do not penetrate into the interior. This reflection and absorption effect significantly reduces the interference of external electromagnetic waves on the internal circuits.

[0066] At the same time, for internally generated electromagnetic waves (such as high-frequency noise in circuits), grounding can provide a low-impedance path so that the energy of these electromagnetic waves is quickly guided to the ground instead of leaking out through shell gaps or other paths.

[0067] Therefore, grounding can make the first housing 11 an effective electromagnetic shielding layer. The second housing 14 is electrically connected to the first housing 11, and the cooling module 12 is electrically connected to the first housing 11. In this way, the entire housing assembly of the control device can be effectively grounded through the grounding terminal, thereby improving the electromagnetic shielding performance of the entire housing assembly and enhancing the electromagnetic compatibility and anti-interference capabilities of the entire housing assembly.

[0068] In a feasible embodiment, the second shell 14 and the extension portion 122 are welded together via the welding block 3 .

[0069] The welding connection physically forms a seamless connection between the second shell 14 and the cooling module 12 , greatly reducing the possibility of electromagnetic waves leaking through these paths.

[0070] Furthermore, the welded connection enables direct electrical connection between the second housing 14 and the first housing 11 via the extension 122, which is then grounded via the ground terminal. This connection allows each part of the housing assembly to quickly conduct induced current or static charge to the ground, reducing the accumulation of electromagnetic interference and thereby improving the electromagnetic shielding performance of the entire housing assembly.

[0071] The present application also provides a vehicle equipped with the above-mentioned optimized control device. Vehicles using this control device have significant advantages.

[0072] First of all, the use of improved control devices in vehicles can significantly enhance their electromagnetic shielding performance, effectively reducing the impact of external electromagnetic interference on internal electronic systems. This not only improves the stability of the vehicle's electronic systems, but also ensures the efficient operation of various sensors and control modules.

[0073] Secondly, enhanced electromagnetic shielding reduces signal noise and improves data transmission reliability, thereby increasing the responsiveness and accuracy of the vehicle's intelligent systems. These improvements not only optimize the vehicle's overall performance but also enhance safety and the driving experience.

[0074] Furthermore, the control unit's stability and anti-interference capabilities can reduce maintenance costs and improve the vehicle's long-term reliability. These advantages make vehicles equipped with this control unit more competitive in the market and meet modern consumers' demands for high-performance and high-reliability vehicles.

However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
