[0002] In the field of electronic technology for mobile devices, the domain controller, as the control component of mobile devices, undertakes the task of integrating and processing numerous electronic system data and instructions. The stability of its operation directly affects the performance and security of mobile devices.

[0003] Taking domain controllers as an example, as the computational and data transmission volumes of domain controllers increase significantly, the heat generated by them also rises sharply. To ensure the normal operation of domain controllers, the vehicle's water-cooling system is currently used to dissipate heat, thereby maintaining a suitable operating temperature and preventing performance degradation or even failure due to overheating.

[0004] However, when debugging and verifying the domain controller, the relevant technologies require removing the entire domain controller from the vehicle. This disassembly process is not only complex and cumbersome, reducing the efficiency of debugging and verification analysis, but also, after being removed, the domain controller is separated from the vehicle's water-cooling system and cannot achieve effective heat dissipation. This can easily lead to new faults or problems due to overheating during debugging, affecting the accuracy and reliability of the debugging results. Utility Model Content

[0026] In related technologies, domain controllers, as control components of mobile devices, are responsible for integrating and processing data and instructions from numerous electronic systems. Their operational stability directly impacts the performance and security of mobile devices. Taking domain controllers as an example, debugging and verifying them requires completely removing the entire controller from the vehicle. This disassembly process is not only complex and cumbersome, reducing the efficiency of debugging and verification analysis, but also, once disassembled, the domain controller is separated from the vehicle's water-cooling system, making effective heat dissipation impossible and potentially leading to new faults or problems due to overheating during debugging.

[0027] The controller provided in this application embodiment achieves electrical connection and data transmission between the controller and the test board through the connection and cooperation of the first connecting part and the test board, so that engineers can capture and analyze data. This application embodiment enables the debugging and testing of the controller without disassembling it, avoiding the heat dissipation and operational complexity problems caused by disassembling the controller, ensuring the accuracy and reliability of the debugging results, while improving testing efficiency and simplifying testing operations.

[0028] Reference Figures 1 to 3 This application provides a controller, which includes: Housing 1, with an opening 11 provided on housing 1; Circuit board 2 is disposed inside housing 1. Circuit board 2 has a test area for detachable installation of first connection part 21. The first connecting part 21 is configured to connect and cooperate with the second connecting part 2001 of the test plate 200 through the opening 11. In the above embodiment, the housing 1 has a cavity inside for mounting components such as circuit boards, providing physical protection for critical components such as circuit boards inside the controller. This prevents damage to internal components from external dust, moisture, collisions, etc., ensuring stable operation of the controller. The opening 11 provides a channel for connecting the test board to the circuit board 2 inside the controller, allowing the test board to easily interact with the controller. Debugging and testing of the controller can be performed without completely disassembling it, thus simplifying the testing process and improving testing efficiency.

[0029] In the above embodiments, the opening 11 can be directly opposite the test area, that is, the projection of the opening 11 on the circuit board 2 is located within the test area, which facilitates the first connection part 21 to be connected to the outside through the opening 11; or the projection of the opening 11 on the circuit board 2 is located outside the test area, and the first connection part 21 of the test area is connected to other components on the opening through wiring, which improves the flexibility of the connection of internal components of the controller.

[0030] See Figure 3 and Figure 4 Circuit board 2 is housed within housing 1. Circuit board 2 carries various electronic components and circuits, enabling the controller to perform data processing and signal control functions. Circuit board 2 has a test area, such as... Figure 4 As shown by the dashed line, the opening 11 on the housing 1 is opposite to the test area on the circuit board 2, ensuring that the test board 200 can easily contact the first connection part 21 of the test area through the opening 11, ensuring the stability of the connection between the test board 200 and the first connection part 21 in the test area, and improving the accuracy and convenience of controller testing.

[0031] In one embodiment, the test area is located at the edge of the circuit board 2.

[0032] In the above embodiment, the edge area of ​​the circuit board 2 can be the area near the edge of the circuit board. For example, the distance between the edge area and the edge of the circuit board is 2-10mm. The test area will not occupy too much space in the middle of the circuit board 2 for arranging the core circuit and functional components, which is conducive to the overall design and component layout optimization of the circuit board 2.

[0033] In addition, from the perspective of operational convenience, the test area located at the edge is easier for testers to access and operate, and can quickly complete the installation and disassembly of the first connection part 21, improving the convenience and efficiency of test operations.

[0034] In one embodiment, the projection of the opening 11 on the circuit board 2 is located in the test area, ensuring that the connection operation performed from the housing opening 11 can be efficiently and accurately mapped to the test area on the circuit board 2. This allows the second connection part to be smoothly connected to the first connection part 21 in the test area, avoiding connection difficulties or unstable connection problems caused by positional deviations. This improves the accuracy and reliability of electrical connections and data transmission, and ensures the accuracy and reliability of the connection.

[0035] In some embodiments, the first connecting part 21 can be detachably installed in the test area by snap-fit ​​or plug-in, so that the first connecting part 21 can be flexibly installed as needed during debugging, and the first connecting part 21 can be easily disassembled after the controller is mass-produced, which improves the flexibility of testing and can adapt to different test requirements and scenarios.

[0036] The controller 100 provided in this embodiment achieves electrical connection and data transmission between the controller 100 and the test board 200 through the connection and cooperation of the first connecting part 21 and the second connecting part 2001, so that engineers can capture and analyze data. This connection method does not require disassembling the controller 100, thus avoiding heat dissipation problems and operational complexity caused by disassembling the controller 100, ensuring the accuracy and reliability of debugging results, and improving testing efficiency.

[0037] In another embodiment, by installing the first connection part 21 in the test area of ​​the circuit board 2, the controller 100 can be debugged through the first connection part 21 before mass production, and tested through the first connection part 21 after mass production, thus ensuring the efficiency of debugging analysis before mass production and the efficiency of problem testing analysis after mass production.

[0038] In some embodiments, the test area is provided with a connection contact point for electrical connection with the first connection portion 21.

[0039] In the above embodiments, the delineation of the test area provides a clear operational scope for the testing work, avoiding interference or misoperation to other non-test-related areas on the circuit board 2, ensuring the accuracy and relevance of the test, and improving testing efficiency. Simultaneously, the centralized test area facilitates the unified layout and management of the circuits and components required for testing, and simplifies the connection and debugging of the test equipment. The connection point, as the electrical connection point between the internal circuitry of the controller and the external test device via the first connection part 21, plays a crucial role in signal transmission and power conduction, ensuring stable and accurate exchange of data and signals between the test device and the controller during the test process, thereby achieving effective testing of the controller 100's functions and performance.

[0040] In some embodiments, see Figure 4 The test area is provided with positioning holes 22, which are used to be fitted and cooperate with the positioning posts 211 on the first connecting part 21.

[0041] In the above embodiment, the positioning holes 22 on the test area provide a precise positioning reference for the connection between the first connecting part 21 and the test area. During the test, the first connecting part 21 can be quickly and accurately installed into the designated position through one or more positioning holes 22, avoiding deviations that may occur during manual installation and improving the accuracy and efficiency of installation. At the same time, the positioning holes 22 help ensure accurate docking between the first connecting part 21 and related circuits or components within the test area, ensuring the reliability of electrical connections and reducing test errors or failures caused by inaccurate connections.

[0042] In one specific embodiment, the positioning post 211 and the positioning hole are fitted together to form a stable mechanical connection structure. This not only enhances the installation stability of the first connection part in the test area and prevents loosening or displacement due to vibration or external force during the test, ensuring the continuity and stability of the test, but also makes the connection tighter. This helps to improve the signal transmission quality of the electrical connection, reduce signal interference and loss, and thus improve the performance and reliability of the entire test system.

[0043] In another embodiment, a positioning post is provided in the test area, and a positioning hole is provided on the first connecting part 21. The positioning hole and the positioning post are fitted together, which can also achieve stable installation of the first connecting part in the test area.

[0044] In some embodiments, see Figure 5 and Figure 6 The first connecting part 21 has a mounting surface and a connecting surface that are opposite to each other, and the mounting surface is configured to contact and cooperate with the test surface; The connecting surface is provided with a plurality of plug-in terminals 212, which are configured to plug into and cooperate with a plurality of elastic terminals 20011 of the second connecting part 2001.

[0045] In the above embodiment, the mounting surface contacts the test surface and is electrically connected to the circuit board 2 through the contact point. This enables stable signal transmission and power conduction between the first connection part 21 and the circuit board 2, allowing the test signal to be transmitted accurately and efficiently between the controller and the test device. Moreover, the contact mating method has adaptive capabilities, which can compensate for minor errors during the installation process, ensuring the reliability of the connection, thereby ensuring the stability of signal transmission during the test and improving the accuracy of the test results.

[0046] See Figure 6 The multiple connectors 212 enhance the connectivity and signal transmission capabilities of the first connection section 21. Different connectors 212 can transmit different types of signals, such as data signals and power signals, meeting the requirements for simultaneous transmission of multiple signals in complex controller circuit systems. Furthermore, the multiple connectors 212 design increases connection redundancy; if one connector 212 fails, the others can still function normally, ensuring the stability and reliability of the testing system.

[0047] See Figure 3 , Figure 6 and Figure 7 The multiple plug-in terminals 212 are configured to plug into and cooperate with the multiple elastic terminals 20011 of the second connection part 2001, which makes the connection and disconnection operation of the first connection part 21 and the second connection part 2001 simpler and improves the efficiency of testing and debugging.

[0048] Meanwhile, the flexible terminal 20011 possesses excellent elasticity and conductivity, providing stable contact pressure when it is plugged into the mating terminal 212. This ensures the reliability of the electrical connection and reduces signal interference and errors caused by poor contact. Furthermore, the flexible terminal 20011 also acts as a buffer, absorbing vibration and impact, protecting the mating terminal 212 from damage, extending the service life of the connecting components, and improving the precision and accuracy of the connection.

[0049] In some embodiments, the controller 100 further includes a cover plate that is mounted in the opening 11 and used to seal the housing 1.

[0050] In the above embodiment, the cover plate is installed at the opening 11 to close the opening of the housing 1. The opening 11 serves as a channel on the housing for debugging. After debugging is completed, the cover plate can promptly fill the opening, restoring the integrity of the housing 1. This ensures that the housing has good sealing performance under normal use, preventing external substances from entering the housing through the opening and ensuring the stability of the internal environment of the controller 100.

[0051] See Figure 8 and Figure 9 This application provides a testing device, which includes a test board 200 and the controller 100 described above; The test board 200 is connected and mated with the circuit board 2 of the controller 100.

[0052] In the above embodiments, the test board 200 can integrate test circuits, signal processing modules, and connection interfaces with the object under test (controller 100). The test board 200 can simulate different working scenarios and input signals to perform comprehensive functional testing, performance evaluation, and fault diagnosis of the controller 100, providing a signal interaction channel for the testing process and ensuring that the testing can be conducted accurately and effectively.

[0053] This embodiment establishes an electrical path between the test board 200 and the circuit board 2 of the controller 100, enabling the test board 200 to input test signals, such as simulated sensor signals and control commands, to the controller 100, and simultaneously receive output signals from the controller 100, such as processed data and status information. Through this bidirectional signal transmission, comprehensive testing of the controller 100's functions and performance is achieved.

[0054] In some embodiments, a test circuit is provided on the test board 200, which is used to connect an external test device.

[0055] In the above embodiments, a test circuit is provided on the test board 200. The test circuit can preprocess the input test signal, such as filtering, amplification, and shaping, to convert signals of different types and specifications into signal forms suitable for processing by the object under test (such as a controller).

[0056] Simultaneously, the test board 200 can also acquire, convert, and analyze the signals output by the device under test (DUT) to accurately obtain its performance parameters and operating status. For example, the test board 200 can simulate different working scenarios and fault conditions to perform comprehensive functional testing and fault diagnosis on the DUT, helping to discover potential problems in the design and manufacturing process of the DUT and improve product quality and reliability.

[0057] In addition, external testing equipment can provide more testing functions for the test circuit, expanding the capabilities of the test system and meeting the needs for more comprehensive and in-depth testing of the object under test. For example, connecting a high-precision signal generator to the test circuit can provide more accurate and stable test signals.

[0058] In some embodiments, see Figure 9 The testing equipment also includes a protective cover 202, which is located on the side of the test board 200 away from the controller 100.

[0059] In the above embodiments, when it is necessary to debug, repair, or replace components on the test board 200, opening the protective cover 202 will not interfere with the connection to the controller 100 or the testing process. Operators can easily access relevant parts of the test board 200, improving testing efficiency and reducing the risk of damage to other components due to improper operation.

[0060] See Figure 9 The protective cover 202 covers the surface of the test board 200 away from the controller 100. During testing, the test equipment may be affected by various external factors, such as accidental collisions, liquid splashes, and dust intrusion. The protective cover 202 can effectively block accidental collisions, liquid splashes, and dust intrusion, reducing damage to critical components such as the test board 200, thereby extending the service life of the test equipment and reducing maintenance costs.

[0061] This application provides a mobile device that includes the controller 100 described above.

[0062] In the above embodiments, the mobile device can be a vehicle, ship, aircraft, robot, or other equipment. For example, the controller 100 is a controller on a vehicle used to control driving automation. The controller 100 achieves electrical connection and data transmission between itself and the test board 200 through the connection and cooperation of the first connecting part 21 and the second connecting part 2001, allowing engineers to capture and analyze data. This connection method enables controller debugging without disassembling the controller 100, thus avoiding heat dissipation and operational complexity issues caused by disassembling the controller 100, ensuring the accuracy and reliability of the debugging results, and improving testing efficiency.
