Description

Technical Field

[0001] This application relates to the field of controller technology, and more particularly to controllers, control systems, electronic devices, and vehicles. Background Technology

[0002] Electromagnetic shielding is a technology that uses conductive or magnetic materials to block the propagation of electromagnetic waves. By reflecting, absorbing, or attenuating electromagnetic energy, it reduces the interference of external electromagnetic fields on equipment or prevents the leakage of internal electromagnetic signals from the equipment.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0055] The inventors discovered that manually attaching conductive foam with double-sided adhesive to connectors can improve electromagnetic shielding leakage to some extent. However, manual attachment of conductive foam is inefficient, and after prolonged use, the double-sided adhesive is prone to peeling off, causing the conductive foam to detach from the connector and thus affecting the effectiveness of electromagnetic shielding.

[0056] Based on this, this application provides a controller, please refer to... Figure 1 and Figure 2 , Figure 1 This is an exploded view of the controller provided in an exemplary embodiment of this application. Figure 2 This is a schematic diagram of the overall structure of the controller provided in an exemplary embodiment of this application. The controller includes:

[0057] The system includes a housing 20, a circuit board assembly 23 disposed within the housing 20, and an electromagnetic shielding mechanism for achieving electromagnetic shielding. The electromagnetic shielding mechanism comprises an electromagnetic shielding element 11 and a support element 13, the support element 13 being disposed within the housing 20 to connect the electromagnetic shielding element 11 to the circuit board assembly 23. In the above technical solution, by connecting the electromagnetic shielding element to the circuit board assembly using the support element, the support element can fix the electromagnetic shielding element between the housing and the circuit board assembly, or between the support element and the circuit board assembly, or between the support element and a connector on the circuit board assembly. The electromagnetic shielding element is subjected to bidirectional pressure from the housing and the circuit board assembly, thereby forming a tight contact with the housing, the circuit board assembly, and the connector, ensuring that the electromagnetic shielding element will not detach even after prolonged use. This tight contact and resistance to detachment of the electromagnetic shielding element guarantees a long-term stable electromagnetic shielding effect.

[0058] In some specific implementations, such as Figure 1As shown, the circuit board assembly 23 includes a main printed circuit board 232, a sub-printed circuit board 231 signal-connected via a third connector 233, and a connector 12 disposed on the circuit board assembly 23. Combined with... Figure 1 and Figure 2 The housing 20 includes an upper housing 21 and a lower housing 22 that are assembled and connected to each other, and a mounting groove 24 for the connector 12 to pass through. The interface of the connector 12 extends out of the housing to facilitate its connection to external devices. The connector 12 includes a first connector 121, a second connector 122, a fourth connector 123, a fifth connector 124, and a sixth connector 125, and all connectors extend out of the housing through the mounting groove.

[0059] In some cases, combined Figure 1 and Figure 9 The sub-printed circuit board 231 includes a plurality of first connectors 121; the first connectors 121 are soldered to the sub-printed circuit board 231 and extend to the outside of the housing 20 to facilitate its connection with external devices.

[0060] In some cases, combined Figure 1 and Figure 9 The main printed circuit board 232 is disposed inside the lower housing 22. The main printed circuit board 232 includes a second connector 122, a fourth connector 123, a fifth connector 124 and a sixth connector 125. Similarly, the second connector, the fourth connector, the fifth connector and the sixth connector all extend to the outside of the housing to facilitate their connection with external devices.

[0061] In some examples, the main printed circuit board 232 is signal-connected to the sub-printed circuit board 231 via a third connector 233.

[0062] In some specific implementations, such as Figure 1 As shown, the support member 13 is disposed within the housing 20 and can securely connect the electromagnetic shielding member 11 and the circuit board assembly 23; as Figure 1 , Figure 3 and Figure 4 As shown, the support member 13 includes a frame 131. A mounting lug 133 is provided on the first end side 1311 of the frame 131. A fixing hole 134 or a fixing post 135 is provided on the mounting lug 133. The frame can be fixed to the printed circuit board through the fixing hole and screws, and the frame can be fixed to the upper shell through the fixing post; or the frame can be fixed to the printed circuit board through the fixing post, and the frame can be fixed to the upper shell through the fixing hole and screws.

[0063] In some examples, connectors protrude from the housing, such as Figure 2 Due to assembly issues, a gap may exist at the portion of the second connector 122 that protrudes from the mounting slot 24. (See attached image) Figure 4 , Figure 5 , Figure 6 A plurality of mounting blocks 136 are provided on the frame 131 via connecting rods 132, and the mounting blocks 136 are located on the second end side 1312 of the frame 131. When the frame is fixed to the housing, the mounting blocks can close the gaps to prevent the circuit board assembly from being directly exposed. The above technical solution uses mounting blocks to cover the structural gaps after the connector is installed, which can prevent the circuit board assembly from being directly exposed and also play a role in dust prevention.

[0064] For example, such as Figure 8 As shown, the upper side or part of the upper side of the mounting block 136 abuts against the sub-printed circuit board 231. When the sub-printed circuit board is subjected to external force, the mounting block can offset the stress generated when the sub-printed circuit board is impacted by external force.

[0065] For example, such as Figure 8 As shown, the lower side or part of the lower side of the mounting block 136 abuts against the main printed circuit board 232. When the main printed circuit board is subjected to external force, the mounting block can offset the stress generated when the main printed circuit board is subjected to external impact.

[0066] For example, such as Figure 8 As shown, the upper side of the mounting block 136 abuts against the sub-printed circuit board 231 and the lower side of the mounting block abuts against the main printed circuit board 232. When the circuit board assembly is subjected to external force, the mounting block can offset the stress generated when the circuit board assembly is subjected to external force impact.

[0067] For example, the mounting block abuts against the edge region of the main printed circuit board and the edge region of the sub-printed circuit board, and a conductive layer is laid in the edge region and at the abutment location. The conductive layer can reduce the ground impedance and improve the anti-interference capability of the circuit board assembly without affecting the thickness of the circuit board assembly.

[0068] Understandably, laying conductive layers on circuit board assemblies, such as filling unused areas or spaces on the main and sub-printed circuit boards with solid copper to form conductive layers, can reduce ground impedance, improve the circuit board assembly's anti-interference capability, and reduce the loop area of ​​the circuit board assembly.

[0069] In some specific implementations, see [reference] Figure 1 , Figure 7 and Figure 8As shown, the electromagnetic shielding component 11 is sandwiched between the upper housing 21 and the sub-printed circuit board 231, and the support component 13 is disposed between the sub-printed circuit board and the main printed circuit board. When fixing the sub-printed circuit board inside the upper housing, the electromagnetic shielding component with adhesive backing is first fixed inside the upper housing using a tooling, and the sub-printed circuit board is fixed to the support component. Then, the support component is fixed inside the upper housing. At this time, the electromagnetic shielding component fixed inside the upper housing is abutted against the sub-printed circuit board. Therefore, the electromagnetic shielding component can be fixed between the housing and the circuit board assembly through the support component.

[0070] For example, the electromagnetic shielding component includes a first shielding component 111. The first shielding component is first fixed to the upper housing using a tooling. The sub-printed circuit board is then fixed inside the upper housing using a frame. The first shielding component will abut against the sub-printed circuit board, thus fixing the first shielding component between the upper housing and the sub-printed circuit board. The first shielding component is subjected to bidirectional pressure from the upper housing and the frame. The first shielding component can form a tight contact with the sub-printed circuit board, making it difficult to fall off and facilitating long-term electromagnetic shielding.

[0071] For example, such as Figure 8 As shown, a conductive layer is laid in the area where the first shield 111 abuts against the sub-printed circuit board 231. The conductive layer can reduce the ground impedance and improve the anti-interference ability of the circuit board assembly without affecting the thickness of the circuit board assembly. In addition, the conductive layer can also enhance the conductive connection between the first shield and the sub-printed circuit board, thereby enhancing the electromagnetic shielding effect.

[0072] In some specific embodiments, the electromagnetic shielding component is fixed to the lower side of the second end of the support component, and the frame abuts against the main printed circuit board through the electromagnetic shielding component. The main printed circuit board is fixed inside the lower housing, thereby achieving that the electromagnetic shielding component is sandwiched between the lower housing and the main printed circuit board. Therefore, the support component can fix the electromagnetic shielding component between the support component and the circuit board assembly.

[0073] In some examples, see Figure 4 , Figure 7 and Figure 8 The electromagnetic shielding component includes a second shielding component 112, which is fixed on the second end side 1312 of the frame. After the main printed circuit board 232 and the support component are assembled, the frame 131 abuts against the main printed circuit board 232 through the second shielding component. The second shielding component is subjected to bidirectional pressure from the frame and the main printed circuit board located in the lower shell. The second shielding component can form a tight contact with the main printed circuit board and is not easy to fall off, which facilitates long-term electromagnetic shielding.

[0074] For example, a conductive layer is laid in the area where the second shielding component abuts against the main printed circuit board. The conductive layer can reduce the ground impedance and improve the anti-interference capability of the circuit board assembly without affecting the thickness of the circuit board assembly. In addition, the conductive layer can also enhance the conductive connection between the second shielding component and the main printed circuit board, thereby enhancing the electromagnetic shielding effect.

[0075] In some specific embodiments, the electromagnetic shielding component includes a third shielding component, which is used to electromagnetically shield the second connector; by fixing the third shielding component to the support component and then attaching the third conductive component to the second connector, electromagnetic shielding of the second connector can be achieved.

[0076] In some examples, see Figure 4 , Figure 6 , Figure 8 and Figure 10 A mounting block 136 is protruding from the second end side 1312 of the frame via a connecting rod 132. The third shield 113 is fixed to the mounting block 136. The second connector 122 is soldered to the main printed circuit board 232. The mounting block is attached to the connector via the third shield and also abuts against the main printed circuit board, which can achieve electromagnetic shielding of the second connector and reduce the stress generated by the main printed circuit board under external impact.

[0077] In some examples, a groove 137 is provided on the mounting block 136, and a third shielding member 113 is fixed in the groove. The third shielding member 113 is attached to the second connector 122, thereby achieving the effect of electromagnetic shielding. Moreover, the third shielding member is stably clamped between the connector and the frame by the bidirectional pressure of the groove and the second connector. In the above technical solution, the support member can fix the electromagnetic shielding member between the support member and the connector, and it is not easy to fall off.

[0078] For example, the first contact side of the third shielding component is in close contact with the sidewall of the groove. For instance, the cross-sectional profile of the first contact side (such as wavy, sawtooth, or stepped) and the shape of the inner wall of the groove (such as V-groove, rectangular groove, or irregular guide groove) form a complementary match, which can ensure a tight fit between the third shielding component and the sidewall of the groove. The third shielding component is not easy to detach from the groove and is tightly fitted to the second connector, thereby achieving a good electromagnetic shielding effect and ensuring that the second connector is not affected by external electromagnetic interference during operation.

[0079] For example, at least a portion of the cross-sectional profile of the second contact side matches the cross-sectional profile of the contact portion of the second connector. For instance, if the contact surface of the second connector is a boss structure, the second contact side of the third shield is configured as a complementary groove shape. Through the matching design, the third shield can achieve seamless or minimal gap contact with the surface of the second connector, preventing electromagnetic interference from leaking or intruding through gaps in the contact interface.

[0080] In some examples, the first connector, second connector, fourth connector, fifth connector, and sixth connector include at least one of a signal connector, a power connector, a filter connector, and a radio frequency connector.

[0081] Understandably, connectors, acting as bridges between different circuits or components, often bear the burden of transmitting high-frequency signals. During high-speed data transmission, the rapid changes in current within the connector generate electromagnetic fields. If these electromagnetic fields are not effectively controlled, they may radiate outwards as electromagnetic waves, thus interfering with surrounding electronic equipment. Furthermore, because connectors are typically exposed without additional shielding, they are more susceptible to external electromagnetic interference, which in turn affects the integrity and stability of data transmitted through them.

[0082] Optionally, signal connectors are primarily used for transmitting data signals. As data transmission rates increase, signal integrity becomes particularly important. Signal connectors are susceptible to external electromagnetic interference and may also be a source of such interference.

[0083] Optionally, the power connector is responsible for providing power to the device. Due to the high current intensity, especially in high-power applications, the power connector can become a strong source of electromagnetic radiation.

[0084] Optionally, filter connectors are specifically designed to remove noise and unwanted frequency components from power lines or other signal lines. In addition to their internal filtering function, filter connectors also require appropriate external shielding to ensure the entire system is protected from external electromagnetic interference.

[0085] Optionally, RF connectors are used to transmit high-frequency signals and are widely used in wireless communication and other fields. Due to their extremely high operating frequencies, RF connectors are highly susceptible to electromagnetic interference and are also a potentially powerful source of interference.

[0086] For example, the main printed circuit board and the sub-printed circuit board are connected by a third connector. The third connector can be a board-to-board connector. A board-to-board connector is a core component for electrical interconnection between different printed circuit boards in electronic devices. It realizes signal transmission, power supply and data communication between circuit boards through precision contact points, while ensuring the stability and reliability of the connection.

[0087] In some specific embodiments, the controller includes a domain controller; the domain controller includes at least one of a powertrain domain controller, a chassis domain controller, a cockpit domain controller, an autonomous driving domain controller, a body domain controller, and a powertrain domain controller.

[0088] For example, in new energy vehicles, the powertrain domain controller mainly refers to the integration of electric drive and electronic control systems. This might involve integrating the motor, electronic control unit (inverter), and reducer into a single electric drive axle. The integration of the electronic control system tends to be a multi-functional module, typically integrating transformers, on-board chargers, heaters, and even the vehicle control unit (VCU). The powertrain domain controller is primarily responsible for the optimization and control of the powertrain, including transmission management, engine management, battery monitoring, and alternator regulation. The domain controller can calculate and distribute torque for various powertrain units, achieving energy conservation and emission reduction through predictive driving strategies. It also possesses functions such as intelligent electrical fault diagnosis, intelligent power saving, and bus communication.

[0089] For example, the chassis domain controller is primarily responsible for specific vehicle driving control, including the power steering system, vehicle stability system, electric brake booster, airbag control system, air suspension, and vehicle speed sensors. In autonomous driving scenarios, the chassis domain controller precisely controls the vehicle's steering, braking, and driving posture according to the instructions of the autonomous driving domain controller to ensure safe driving under various road conditions.

[0090] For example, the cockpit domain controller mainly controls the functions of various electronic information systems in the vehicle's intelligent cockpit, such as the central control system, in-vehicle infotainment system, head-up display, seat system, instrument system, rearview mirror system, driving behavior monitoring system, navigation system, etc.

[0091] For example, the autonomous driving domain controller undertakes the data processing, computation, and judgment capabilities required for autonomous driving, including data processing of devices such as millimeter-wave radar, cameras, lidar, GPS, and inertial navigation.

[0092] For example, the body domain controller is mainly responsible for the overall control of the body functions. It is based on the traditional body controller and integrates functions such as keyless start system, ripple anti-pinch system, and air conditioning control system.

[0093] Understandably, circuit board assemblies themselves are a significant source of electromagnetic interference. Especially in modern electronic devices, with increased integration and higher operating frequencies, the trace density on PCBs (printed circuit boards) increases, making crosstalk, reflection, and radiation between signals more severe. For example, in high-speed digital circuits, signal rise and fall times become extremely short, resulting in a large number of high-frequency harmonic components, which can easily generate radiated interference.

[0094] For example, a circuit board assembly refers to the mounting of various electronic components (such as resistors, capacitors, inductors, chips, etc.) on a printed circuit board and fixing them by soldering or other connection methods to form a complete circuit system. The circuit board assembly is the core part of electronic equipment and is responsible for realizing specific electronic functions, such as signal processing, power management, data transmission, etc.

[0095] In some specific embodiments, the electromagnetic shielding component is selected as a resilient electromagnetic shielding component. By selecting a resilient electromagnetic shielding component, mechanical vibration or deformation can also be absorbed, protecting the circuit board assembly and the connectors on the circuit board assembly from damage.

[0096] In some examples, elastic electromagnetic shielding components include at least one of conductive foam, conductive silicone, and conductive rubber. These shielding components contain conductive elements (such as metal fibers, silver particles, or carbon), giving them excellent conductivity. When electromagnetic waves encounter these shielding components, most of the energy is reflected back. Furthermore, the elasticity of the shielding components allows them to maintain tight contact on irregular or varying surfaces. They can fill tiny gaps between connectors, housings, or other electronic devices, forming a continuous conductive layer. This not only prevents electromagnetic waves from leaking out or intruding through unprotected gaps, but also ensures electrical continuity and enhances the overall shielding effect.

[0097] For example, conductive foam is a composite material in which metal fibers or conductive particles are embedded into a foam material. Conductive foam possesses good elasticity, compression recovery, and excellent conductivity. Due to its numerous interconnected conductive paths, it effectively reflects and absorbs electromagnetic waves, thus providing shielding. Furthermore, conductive foam is lightweight, making it suitable for applications requiring frequent disassembly and reassembly, such as the seams of electronic device housings, to ensure continuous electromagnetic sealing.

[0098] For example, conductive silicone is a composite material made by adding conductive fillers such as silver, nickel, and carbon to a silicone substrate. Conductive silicone combines the excellent properties of silicone, such as heat resistance, cold resistance, and aging resistance, with the conductivity provided by the conductive fillers. Due to its softness and plasticity, conductive silicone can fill the tiny gaps between irregular surfaces, ensuring electrical continuity and effectively preventing the penetration of electromagnetic waves.

[0099] For example, conductive rubber, similar to conductive silicone, achieves conductivity by adding conductive fillers to a rubber substrate. Conductive rubber is commonly used in the manufacture of electromagnetic shielding gaskets, seals, etc., especially in applications requiring high compressive strength, where it provides durable mechanical protection while maintaining good electromagnetic shielding performance.

[0100] In some specific implementations, see [reference] Figure 1 , Figure 3 , Figure 4 and Figure 9 As shown, the assembly process of the controller is as follows:

[0111] During the manufacturing process, the electromagnetic shielding components are pre-fixed to the support components or the upper shell using tooling or other mechanical means; by pre-fixing, no manual pasting is required, thereby improving installation efficiency and fixing effect;

[0112] During the assembly stage, the electromagnetic shielding component is fixed to the circuit board assembly by a support member. The electromagnetic shielding component is sandwiched between the housing and the circuit board assembly. The housing and the circuit board assembly apply bidirectional pressure to the electromagnetic shielding component, and the electromagnetic shielding component directly forms a tight contact with the connector or circuit board assembly.

[0113] During equipment operation, the electromagnetic shielding component inside the controller not only plays a crucial role in electromagnetic shielding but also absorbs impacts caused by mechanical vibration or deformation, effectively protecting the circuit board assembly 2 and connectors from potential damage. Even after prolonged use, the electromagnetic shielding component will not detach due to material aging or environmental factors, ensuring a long-term, stable, and highly efficient electromagnetic shielding effect.

[0114] Meanwhile, by placing the support between the main printed circuit board and the sub-printed circuit board, and by also covering the holes formed after the connector is installed, the circuit board components are prevented from being directly exposed and the dustproof effect is achieved.

[0115] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0116] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0117] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0118] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
