[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] In related technologies, when operating the circuit board installed in the controller to locate and operate specific faulty locations and circuits on the circuit board, it is necessary to forcibly remove the circuit board from the controller's casing. However, the circuit board and casing in the controller are generally fixedly connected by methods such as adhesive or soldering. Forcibly removing the circuit board can damage it and increases the number of steps required to operate the circuit board, resulting in low operating efficiency.

[0039] When a circuit board failure occurs during use, the controller provided in this application embodiment can directly obtain the operation information of the operation points on the circuit board through the operation device while the circuit board is connected to the housing. Then, the operation information can be collected and analyzed through the operation device to locate the specific fault location and fault circuit on the circuit board in a timely and accurate manner, thereby improving the efficiency of the circuit board operation and ensuring the structural integrity of the circuit board.

[0040] Reference Figure 1 and Figure 2 This application provides a controller, which includes:

[0041] The housing 100 and the cover plate 200 are provided. The housing 100 has an opening on one side, and the cover plate 200 is connected to the housing 100 and can expose the opening.

[0042] Circuit board 300 is fixed to housing 100. Multiple operating points 303 of circuit board 300 converge on the side of circuit board 300 facing the opening, that is, all operating points 303 of circuit board 300 are formed on the side of circuit board 300 facing the opening.

[0043] In this embodiment, the housing 100 and the cover plate 200 are connected relative to each other to form the housing of the controller, which can protect the internal circuit boards and other devices.

[0044] See Figure 1 The housing 100 has an internal cavity, and one side of the housing 100 has an opening. For example, when the controller is installed, the housing 100 has a downward or upward opening. The circuit board 300 can be conveniently and quickly installed into the cavity inside the housing 100 through the opening. For example, the circuit board 300 can be installed into the housing 100 by means of bonding or welding, ensuring the stability of the installation of the circuit board 300.

[0045] In this embodiment, one side of the circuit board 300 can be fixed inside the housing 100, and the other side of the circuit board 300 can face an opening on the housing 100. The cover plate 200 is openably connected to the opening, so that the surface of the circuit board 300 facing the opening can be exposed when the cover plate 200 is removed from the housing 100. The side of the circuit board 300 facing the opening has multiple operating points 303, so that the circuit board 300 can be operated by an operating device without removing the circuit board 300.

[0046] In this embodiment, the operating point 303 can be a test point on the circuit board 300, facilitating the testing of electrical faults in the circuit board 300. The operating point 303 can also be a mounting point for fasteners such as mounting bolts, facilitating the connection of the circuit board 300 to other mechanisms. Furthermore, the operating point 303 can be a plug-in / plug-out point for devices such as fuses, improving the ease of connecting and removing devices on the circuit board 300.

[0047] In some embodiments, the cover plate 200 may be detachably connected to the opening, for example, by means of bolts or clips, to facilitate the assembly and disassembly of the cover plate 200; or the cover plate 200 may be rotatably connected to the opening, for example, by means of a pivot or opening / closing component, to facilitate the flexible opening and closing of the cover plate 200.

[0048] It is worth noting that when the cover plate 200 opens the opening to expose multiple operating points 303 on the circuit board 300, the cover plate 200 can completely expose the opening or expose only a portion of the opening, as long as the multiple operating points 303 on the circuit board 300 are exposed. Similarly, when the cover plate 200 is connected to the opening to cover it, the cover plate 200 can partially or completely cover the opening, or the cover plate 200 can only cover a portion of the opening, as long as the multiple operating points 303 on the circuit board 300 are covered.

[0049] In one specific embodiment, the operating device performs testing and analysis on the circuit board 300 to be operated by contacting the operating point 303. For example, the operating point 303 on the circuit board 300 to be operated can be a debug (computer troubleshooting) test point. By contacting the debug test point, the operating device can locate the circuit problem on the circuit board 300 to be operated. It can not only determine whether the circuit board 300 to be operated is qualified, but also accurately determine the fault point on the circuit board 300 to be operated.

[0050] In this embodiment, since the surface of the circuit board 300 facing the opening can be exposed when the cover plate 200 is removed from or flipped from the housing 100, when multiple operation points 303 on the circuit board 300 are operated while the circuit board 300 is fixed to the housing 100, the operation points 303 are located in easily exposed spaces, and the operation process will not damage the structure of the circuit board 300 itself. For example, only the cover plate 200 of the controller can be removed or flipped to expose the operation area of ​​the circuit board 300 to be operated, which is provided with multiple operation points 303. Then, the housing 100 with the circuit board 300 to be operated fixed in the controller can be directly fixed. That is, the circuit board 300 can be operated without removing it from the housing 100. Figure 2 and Figure 3 As shown, this avoids damage to the circuit board 300 caused by removing it from the housing 100, thus ensuring the structural integrity of the circuit board 300.

[0051] After the circuit board 300 in the controller has been operated, the cover plate 200 can be reinstalled at the opening of the housing 100 to ensure the structural integrity of the controller. When installing the controller, the cover plate 200 can be placed at the bottom of the controller, that is, as the bottom plate of the controller; or the cover plate 200 can be placed at the top of the controller, that is, as the top plate of the controller.

[0052] The controller provided in this application embodiment can directly obtain the operation information of the operation point 303 on the circuit board 300 through the operation device without damaging the connection between the circuit board 300 and the housing 100. Then, the operation information collection and subsequent analysis can be completed through the operation device, thereby improving the efficiency of the circuit board 300 in operation.

[0053] In one embodiment, the circuit board 300 is non-removably fixed to the housing 100;

[0054] With the cover plate 200 exposing the opening, the operating point 303 of the circuit board 300 can be operated.

[0055] In the above embodiments, non-detachable connection means that after connection, it cannot be separated non-destructively. For example, the circuit board 300 is fixedly connected to the housing 100 by means of welding or gluing, so that the circuit board 300 and the housing 100 are irreversibly connected and the circuit board 300 cannot be removed from the housing 100 without damage.

[0056] The non-removable fixing method makes the circuit board 300 and the housing 100 a stable whole. After the housing 100 is fixed, the circuit board 300 will not loosen or shift, ensuring the stability and efficiency of operating the circuit board 300 through the operating point 303. When the circuit board 300 malfunctions, the operating point 303 on the circuit board 300 can be directly inspected through the exposed opening, ensuring inspection efficiency and reducing maintenance difficulty.

[0057] In one embodiment, multiple operation points 303 are located at the corners of the circuit board 300 on the side facing the opening.

[0058] In the above embodiments, when operating the circuit board 300 of the controller, the operation analysis of the circuit board 300 to be operated can be performed by contacting the operation point 303 with the operating device. Concentrating the operation point 303 in a local area on the side of the circuit board 300 facing the opening, such as multiple operation points 303 located at the corner of the side of the circuit board 300 facing the opening, can avoid the multiple operation points 303 being too dispersed. On the one hand, it is convenient for the operating device to align and contact with the operation point 303, improving the accuracy and efficiency of the operation; on the other hand, it can reduce the structural size of the operating device, ensure the structural compactness of the operating device, and optimize the manufacturing cost of the operating device.

[0059] In one specific embodiment, see Figure 2 The circuit board 300 is square in shape, and multiple operation points 303 are located in the operation area in the upper left corner of the circuit board 300. The range of the operation area can be defined using... Figure 2The dashed box in the diagram illustrates that the complete operation of the circuit board 300 can be achieved when the operating device is only opposite to the operating area in the upper left corner of the circuit board 300, thus ensuring the efficiency of the operation.

[0060] In one embodiment, multiple operation points 303 are located in multiple sub-regions on the side of the circuit board 300 facing the opening, so that the operation points 303 are close to the corresponding operated device, thereby improving operation efficiency.

[0061] In one embodiment, concentrating the operation points 303 on an operation area on one side of the circuit board 300 helps to divide the circuit board 300 into multiple functional modules, for example, see [link to relevant documentation]. Figure 2 The upper left corner of the circuit board 300 facing the opening is divided into an operation area module, the lower right corner of the circuit board 300 facing the opening is divided into an analog area module, and the middle of the circuit board 300 facing the opening is divided into a high-speed area module, which facilitates the modular design and optimization of the circuit board 300.

[0062] In one embodiment, multiple operating points 303 are distributed on one side of the circuit board 300 facing the opening.

[0063] In the above embodiments, when operating the circuit board 300 of the controller, the circuit board 300 to be operated can be analyzed by contacting the operation point 303 with the operating device. When the operating device contacts the operation point 303, stress will be generated at the operation point 303. The multiple operation points 303 on one side of the circuit board 300 are evenly distributed, which can reduce or even avoid the problem of uneven stress on the circuit board 300 during operation and ensure the structural integrity of the circuit board 300.

[0064] In this embodiment, there is a gap between the operation point 303 and the edge of the circuit board 300. The gap can be greater than or equal to 5mm to prevent the circuit board 300 from being damaged due to force on the edge of the circuit board 300 during operation.

[0065] In this embodiment, the operation point 303 can be an electrical test point. There is a minimum distance between two adjacent operation points 303. The minimum distance can be greater than or equal to 2mm to avoid mutual interference or short circuit between adjacent operation points 303 during operation.

[0066] In one embodiment, see Figure 1 A support column 101 is provided inside the housing 100, and the side of the circuit board 300 facing away from the opening is fixed to the support column 101.

[0067] One side of the circuit board 300 is fixed inside the housing 100, and the other side of the circuit board 300 faces the opening of the housing 100. This allows for the operation of multiple operating points 303 on the other side of the circuit board 300 through the opening while ensuring the stability of the circuit board 300.

[0068] In the above embodiment, one side of the circuit board 300 to be operated is fixed inside the housing 100 by the support column 101. The support column 101 provides a stable support for the circuit board 300, preventing the circuit board 300 from being displaced or deformed due to vibration or external force, thereby ensuring the stability and reliability of the circuit board 300. The other side of the circuit board 300 to be operated faces the removable cover plate 200. An operation point 303 can be set on the other side of the circuit board 300 to be operated, so that the operation of the circuit board 300 to be operated can be carried out only when the cover plate 200 is removed.

[0069] In some embodiments, the circuit board 300 has a high-speed region and an operating region, the high-speed region being used to house high-speed devices, and a plurality of operating points 303 located in the operating region.

[0070] In the above embodiment, at least a portion of the area of ​​the circuit board 300 facing the opening is divided into a high-speed area and an operation area. The high-speed area is used for the installation of high-speed devices such as high-speed processors and high-speed memory, which can provide a good environment for the transmission and processing of high-speed signals, reduce signal interference and distortion, and ensure the fast and accurate transmission of high-speed signals.

[0071] See Figure 2 The operation area can be centrally set with operation points 303, which means that operation points 303 are concentrated in non-high-speed areas to avoid contact with high-speed lines and other high-speed devices; this facilitates effective operation and debugging of the circuit board 300, and improves the efficiency and quality of operation.

[0072] In some embodiments, the circuit board 300 includes at least one inner layer and a first outer layer and a second outer layer disposed on both sides of the inner layer. The inner layer is used to provide high-speed signal lines, a plurality of operating points 303 are located on the first outer layer, and the second outer layer is fixed to the housing 100.

[0073] Among them, the projections of multiple operation points 303 on the inner layer are staggered from the high-speed signal lines.

[0074] In the above embodiments, the circuit board 300 forms a multi-layer structure through one or more inner layers in conjunction with a first outer layer and a second outer layer. This multi-layer structure allows for the arrangement of more circuit components and lines within a limited space, improving the integration of the circuit board 300 and enabling it to perform more complex functions. Different layers of the circuit board 300 can be electrically connected through vias or other means to reduce interference between signals, improve signal transmission quality and stability, and thus enhance the overall performance of the circuit.

[0075] Furthermore, the inner shielding effect can reduce the impact of external electromagnetic interference on high-speed signals, avoid mutual interference between high-speed signals and other low-speed signals or control signals, reduce signal attenuation, and ensure that high-speed signals can be transmitted accurately and quickly.

[0076] The arrangement of the first and second outer layers increases the heat dissipation area of ​​the circuit board 300, helping to dissipate the heat generated during circuit operation and improving circuit reliability. Simultaneously, the outer layers facilitate maintenance and repair of the circuit board, as well as the setting of operating points 303 and troubleshooting.

[0077] When a circuit board malfunctions, various fault parameters of the circuit can be quickly obtained through the operation point 303 on the first outer layer, which facilitates fault location and diagnosis and provides an accurate basis for maintenance.

[0078] The second outer layer is fixed to the housing 100, which realizes the mechanical connection between the circuit board 300 and the housing 100. The housing 100 provides protection and support for the circuit board 300, ensuring the stable installation of the circuit board 300 in the housing 100 and preventing the circuit board 300 from shaking or shifting during operation.

[0079] In the above embodiments, the high-speed signal line is highly sensitive to the electromagnetic environment. If the projection of the operating point 303 overlaps with the high-speed signal line, the interference signal introduced by the operating point 303 may affect the transmission quality of the high-speed signal, or even cause signal errors. By staggering the operating point 303 from the high-speed signal line, the mutual interference between the operating point 303 and the high-speed signal can be effectively reduced, improving the purity and stability of the high-speed signal and ensuring the normal operation of the system.

[0080] In one embodiment, the controller further includes a heat-conducting element disposed between the support column 101 and the circuit board 300.

[0081] In the above embodiment, the circuit board 300 is provided with electronic components on the side opposite to the opening, and the electronic components and the support column 101 are opposite to each other so that the heat-conducting component is sandwiched between the electronic components and the support column 101.

[0082] The heat-conducting component can effectively transfer the heat generated by the electronic components on the circuit board 300 to the support column 101, and then dissipate it to the external environment through the housing 100 or other heat dissipation structures. This improves the heat dissipation efficiency of the controller, helps to reduce the operating temperature of the circuit board 300 and its electronic components, and can extend the service life of the circuit board 300 and electronic components.

[0083] In one embodiment, the controller further includes an adhesive element, through which the circuit board 300 is fixed to the support post 101.

[0084] In the above embodiments, the adhesive can quickly and easily fix the circuit board 300 onto the support column 101 inside the housing 100, improving the installation efficiency of the circuit board 300 and ensuring the stable setting of the circuit board 300 on the support column 101.

[0085] In one embodiment, the adhesive can be a thermally conductive adhesive or other adhesive with good thermal conductivity. The adhesive can effectively transfer the heat generated by the circuit board 300 to the support column 101, and then dissipate it to the external environment through the housing 100, thereby improving the heat dissipation efficiency of the controller.

[0086] In one embodiment, see Figure 3 The housing 100 is provided with a fixing structure 102, which is configured to be fixedly connected to the operating device.

[0087] In the above embodiments, when operating the circuit board 300 of the controller, the circuit board 300 to be operated can be analyzed by contacting the operation point 303 with the operating device. The fixed structure 102 ensures a stable connection between the housing 100 and the operating device, preventing the circuit board 300 from shaking or displacing due to unstable connection during operation, thereby improving the stability of operation and the accuracy of operation results.

[0088] In one embodiment, the operating device further includes a carrier 5 having a plurality of support columns configured to support the housing 100. For example, fixing blocks are provided at the corners of the housing 100. The fixing blocks and the support columns are connected and fixed by locking components such as pins and screws. The carrier 5 provides stable support for the housing 100, ensuring the stability of the entire operation process.

[0089] In some embodiments, see Figure 2 and Figure 3 The circuit board 300 is provided with mating points 301, and the mating points 301 and multiple operating points 303 are located on the same side of the circuit board 300.

[0090] The mating point 301 is configured to connect to the connection point 11 on the operating device, which is used to operate multiple operating points 303 on the circuit board 300.

[0091] In the above embodiments, the mating point 301 on the circuit board 300 mates with the connection point 11 on the operating device, thereby enabling a detachable connection of the operating device to the circuit board 300 to be operated. For example, the mating point 301 can be a hook or a snap fastener, and the connection point 11 can be a snap fastener or a hook. The detachable connection of the operating device to the circuit board 300 to be operated is achieved through the snap-fit ​​engagement between the snap fastener and the hook. The mating point 301 has a first threaded hole, or the connection point 11 is a connecting block with a second threaded hole. The locking member achieves a detachable connection of the operating device to the circuit board 300 to be operated through the locking engagement of the first threaded hole and the second threaded hole. This ensures the stability of the circuit board 300 when it is installed on the housing 100 and facilitates the removal of the operating device from the circuit board 300 to be operated.

[0092] In some embodiments, see Figure 5 The circuit board 300 is provided with positioning holes 302, and the positioning holes 302 and multiple operating points 303 are located on the same side of the circuit board 300.

[0093] The positioning hole 302 is configured to engage with the positioning post 12 on the operating device, which is used to operate multiple operating points 303 on the circuit board 300.

[0094] In the above embodiments, when connecting the operating device to the circuit board 300 to be operated, the positioning post 12 on the connector 1 of the operating device can be aligned with the positioning hole 302 on the circuit board 300 to be operated. The positioning post 12 and the positioning hole 302 provide precise positioning for the installation of the operating device on the circuit board 300 to be operated, ensuring the position accuracy of the circuit board 300 to be operated during the operation process, thereby improving the efficiency of the circuit board 300 operation.

[0095] In one embodiment, the controller is a domain controller.

[0096] In the above embodiments, because domain controllers have more complex functions and higher performance requirements, a failure in the circuit board within the domain controller can significantly impact the operation of the entire application system (such as a vehicle system). Timely and accurate location of the specific fault location and faulty circuit on the circuit board can significantly improve the performance and reliability of the domain controller. Furthermore, performing fault operations directly on the circuit board inside the housing without disassembling it can meet the requirements of the complex circuit structure and fault location of the domain controller, ensuring the efficiency of its operation and maintenance.

[0097] In one embodiment, see Figures 4 to 5 The operating device for operating the circuit board 300 includes:

[0098] Connector 1, with guide 2 provided on connector 1, connector 1 is configured to connect to circuit board 300 to be operated;

[0099] Operation component 3 includes operation frame 31 and operation device 32. Operation device 32 is disposed on operation frame 31. Operation frame 31 is movably connected to connector 1 through guide 2.

[0100] The operating frame 31 can move closer to or further away from the circuit board 300 to be operated along the guide 2 so that the operating device 32 can contact the circuit board 300 to be operated or separate from the circuit board 300 to be operated.

[0101] In this embodiment, the connector 1 can be a connecting plate or a connecting platform of the operating device, so that while carrying the operating component 3, it can be connected to the circuit board 300 to be operated, ensuring the structural compactness between the operating device and the circuit board 300 to be operated during operation.

[0102] In one embodiment, see Figure 6 The connector 1 has four corners. A set of opposite corners are provided with positioning posts 12 to facilitate precise positioning of the operating device on the circuit board 300 to be operated; another set of opposite corners are provided with connection points 11 to facilitate detachable connection of the operating device on the circuit board 300 to be operated.

[0103] join Figure 4 and Figure 6 When the operating device operates the circuit board 300 to be operated, the connector 1 can be connected to the circuit board 300 to be operated, so as to form the operating device and the circuit board 300 to be operated into a whole, and ensure the relative accuracy between the operating device and the circuit board 300 to be operated.

[0104] See Figure 4 The operating device 32 is disposed on the operating frame 31, and the operating frame 31 is movably connected to the connector 1 via the guide 2. The guide 2 can extend in a direction perpendicular to the circuit board 300 to be operated, so that when the operating frame 31 moves closer to or away from the circuit board 300 to be operated along the guide 2, the operating frame 31 can drive the operating device 32 to move closer to or away from the circuit board 300 to be operated.

[0105] When the operating frame 31 moves the operating device 32 closer to the circuit board 300 to be operated, the operating device 32 can contact the operating point 303 on the circuit board 300 after gradually approaching it. This allows the operating device 32 to perform operation analysis on the circuit board 300. The guide 2 provides a guiding path for the movement of the operating device 32, preventing it from deviating during its approach to the circuit board 300. This ensures the accuracy of the position of the operating device 32 and improves the precision and efficiency of the operating device in operating the circuit board 300.

[0106] After the operating device 32 has finished operating the circuit board 300 to be operated, the operating frame 31 can move the operating device 32 away from the circuit board 300 to be operated, thereby separating the operating device 32 from the circuit board 300 to be operated, facilitating the operation of the replaced circuit board 300. The connection and fixation between the connector 1 and the circuit board 300 to be operated, along with the movement of the operating frame 31 and the operating device 32 along the guide 2, ensures precise positioning between the operating device and the circuit board 300 to be operated. Furthermore, the assembly between the operating device and the circuit board 300 to be operated is simple, improving the convenience and efficiency of operation.

[0107] In some embodiments, see Figure 1 and Figure 2 One end of the guide member 2 is fixed to the connector 1, and the other end of the guide member 2 has a stop part 21;

[0108] The operating frame 31 includes a movable plate 311, which is sleeved on the guide member 2 and located between the connector 1 and the stop part 21.

[0109] In the above embodiment, the guide 2 provides a clear movement path for the movable plate 311 of the operating frame 31, and the operating device 32 is connected to the movable plate 311, ensuring the accuracy of the movement direction of the movable plate 311 driving the operating device 32 when it approaches or moves away from the circuit board 300 to be operated.

[0110] The stop 21 is located at the end of the guide member 2 away from the connector 1. For example, the stop 21 is set at the top of the guide member 2, which limits the range of movement of the movable plate 311 and can prevent the movable plate 311 from moving excessively and detaching from the guide member 2, thus providing the movable plate 311 with an effective range of movement.

[0111] In some embodiments, see Figure 1 and Figure 2 The movable plate 311 is provided with a bearing 312, and the movable plate 311 is sleeved with the guide member 2 through the bearing 312.

[0112] In the above embodiments, the bearing 312 can be a sliding bearing or a linear bearing. The bearing 312 can reduce the frictional resistance when the movable plate 311 moves on the guide member 2, thereby reducing structural wear caused by friction. Moreover, the installation of the bearing 312 can ensure the accuracy and stability of the moving trajectory of the movable plate 311 on the guide member 2, thereby improving the operating accuracy of the operating device 32 on the circuit board 300 to be operated.

[0113] In some embodiments, see Figure 4 and Figure 6 The operating frame 31 includes an elastic element 313, which is disposed between the movable plate 311 and the connecting member 1; or,

[0114] The elastic element 313 is disposed between the movable plate 311 and the stop part 21.

[0115] In the above embodiments, see Figure 4 When the elastic element 313 is disposed between the movable plate 311 and the connecting member 1, the movable plate 311 will compress the elastic element 313 when it moves the operating device 32 closer to the circuit board 300 to be operated. At the same time, the elastic element 313 can absorb the impact and vibration generated when the movable plate 311 moves or is subjected to external force, thereby playing a buffering and shock absorption role and ensuring the stability of the movable plate 311 during movement. After the operating device 32 completes the operation on the circuit board 300 to be operated, the elastic potential energy accumulated by the elastic element 313 after compression can lift the movable plate 311, realize the reset of the operating device 32 and the movable plate 311, and realize the separation of the operating device 32 from the circuit board 300 to be operated.

[0116] When the elastic element 313 is disposed between the movable plate 311 and the stop portion 21, the movable plate 311 will stretch the elastic element 313 when it moves the operating device 32 closer to the circuit board 300 to be operated. At the same time, the elastic element 313 can buffer the impact and vibration generated when the movable plate 311 moves or is subjected to external force, so as to maintain the stability of the movable plate 311 during the movement. After the operating device 32 completes the operation on the circuit board 300 to be operated, the elastic potential energy accumulated by the elastic element 313 after stretching can pull up the movable plate 311, realize the reset of the operating device 32 and the movable plate 311, and realize the separation of the operating device 32 from the circuit board 300 to be operated.

[0117] In some embodiments, see Figure 4 The operating device also includes a drive unit 4, and the operating frame 31 includes an operating frame 314, which is connected to the movable plate 311 and extends toward the drive unit 4.

[0118] The drive unit 4 is configured to drive the operating frame 314 to move, thereby moving the movable plate 311 along the guide member 2.

[0119] In the above embodiments, the driving component 4 can be driven manually, electrically, or by starting. The driving head of the driving component 4 applies driving force to the operating frame 314, so that the operating frame 314 drives the movable plate 311 to move together. By using the operating frame 314 as a bridge, the efficiency of the driving component 4 in driving the movable plate 311 to move can be improved.

[0120] In one embodiment, the drive unit 4 may have positioning and locking functions. For example, the drive head of the drive unit 4 may be attached to the operating frame 314, and the movement distance of the movable plate 311 can be controlled by controlling the movement stroke of the drive head.

[0121] In one embodiment, the operating frame 314 has multiple connecting arms connected to the movable plate 311 to improve the robustness of the connection between the operating frame 314 and the movable plate 311 and ensure the stability of the drive member 4 driving the movable plate 311 to move through the operating frame 314.

[0122] In some embodiments, see Figure 2 , Figure 4 and Figure 6 The operating frame 31 includes a movable plate 311, and the operating device 32 includes an operating plate 321 and a probe 322. The operating plate 321 is disposed on the side of the movable plate 311 away from the connector 1, and the probe 322 is fixed to the movable plate 311 and electrically connected to the operating plate 321.

[0123] The probe 322 is used to contact the operation point 303 on the circuit board 300 to be operated.

[0124] In the above embodiment, the probe 322 is directly fixed to the movable plate 311 and electrically connected to the operation plate 321, which simplifies the transmission path of the operation signal acquired by the probe 322, reduces the possibility of signal attenuation and interference, and thus improves the operation speed and accuracy.

[0125] In this embodiment, see Figure 2 and Figure 4 When the operating device operates the circuit board 300 to be operated, the movable plate 311 can drive the probe 322 to move together, so that the probe can quickly and accurately locate the operation point 303 on the circuit board 300 to be operated, forming a complete operation path; at the same time, through the external signal on the operating plate 321, the signal of the operation point 303 on the circuit board 300 to be operated can be read and analyzed to locate the operation fault of the circuit board 300 to be operated.

[0126] In one embodiment, the operation plate 321 and the movable plate 311 are spaced apart. For example, the operation plate 321 is located on the side of the movable plate 311 away from the circuit board 300 to be operated. By positioning the operation plate 321 away from the circuit board 300 to be operated, the influence of external interference on the operation result is reduced, and the accuracy of the operation is further improved. On the other hand, it can avoid the guide member 2 and provide space for the movement of the movable plate 311.

[0127] In the above embodiments, the probe 322 can pass through the through hole on the connector 1, or the probe 322 can pass from the outer periphery of the connector 1 and then contact the operation point 303 on the circuit board 300 to be operated, both of which can realize the location and operation of the fault on the circuit board 300 to be operated.

[0128] In some embodiments, see Figure 4 and Figure 6 The operating device 32 includes a flexible connector 323, one end of which is connected to the operating plate 321, and the other end of which is connected to the probe 322.

[0129] In the above embodiments, the flexible connector 323 can be a solder wire or a cable. By connecting each pin on the operation board 321 to the probe 322 on the movable board 311 through the flexible connector 323, not only can the installation error of the operation board 321 and the probe 322 be absorbed, but it also helps to ensure a stable connection between the operation board 321 and the probe 322 and ensure the reliability of signal transmission.

[0130] Furthermore, the flexible connector 323 is easy to bend and extend, making its installation more flexible and convenient. During equipment maintenance, if it is necessary to replace or adjust the control panel 321 or probe 322, the flexible connector 323 can also provide greater operating space, reducing the difficulty of maintenance.

[0131] This application provides a vehicle that includes the controller described above.

[0132] In the above embodiments, the controller can be an autonomous driving controller, power controller, chassis controller, or cockpit controller in the vehicle.

[0133] The vehicle controller includes a housing 100 and a cover plate 200. The housing 100 has an opening on one side, and the cover plate 200 is detachably connected to the opening. A circuit board 300 is fixed to the housing 100. The side of the circuit board 300 facing the opening has multiple operation points 303. This allows the operation information of the operation points 303 on the circuit board 300 to be directly obtained through the operating device without damaging the connection between the circuit board 300 and the housing 100. The operation information can then be collected and analyzed by the operating device, thus improving the efficiency of the circuit board 300 in operation.

[0134] This application provides an embodiment of a method for operating a circuit board in a controller, the method including:

[0135] S101 exposes the opening in the housing through the cover plate to reveal multiple operating points that converge on one side of the circuit board.

[0136] In the above embodiments, during the use of the controller, the cover plate covers the side of the circuit board where the operation point is located, which can protect the circuit board and the internal structure of the housing.

[0137] When the controller malfunctions and the circuit board inside the controller needs to be operated, removing or flipping the cover plate from the housing exposes the previously obscured operating points, providing physical space for the operating equipment to directly contact the operating points, thus enabling subsequent operations to proceed smoothly.

[0138] S102, the operating device is brought into contact with the plurality of operating points to operate the circuit board inside the housing.

[0139] During operation of the circuit board in the controller, the operating device establishes an electrical connection with the circuit board by contacting multiple operating points to achieve signal input and output. The operating device can send operating signals to the circuit board and receive response signals returned by the circuit board, thereby detecting and evaluating fault signals of the circuit board.

[0140] In the above embodiments, the steps of removing the cover to expose the operating point and the operating device contacting the operating point are combined to form a complete pre-operation preparation and operation execution process. Removing the cover provides the conditions for the operating device to contact the operating point, while the operating device contacting the operating point enables the actual operation of the circuit board. The two work together to make the entire operation process smoother and more efficient.

[0141] In some embodiments, the method further includes, before exposing the opening of the housing through the cover to reveal a plurality of operating points converging on one side of the circuit board;

[0142] S201, the housing is fixed to the fixed part of the operating device.

[0143] In the above embodiments, fixing the housing to the fixed part of the operating device creates a stable reference platform for the entire operation process. During operation, the circuit board and its housing will not shake or shift, ensuring that the relative position between the operating device and the circuit board remains stable, thus improving the accuracy and reliability of the operation results.

[0144] Furthermore, with the housing fixed in place, operators can more easily operate and adjust the equipment without worrying that movement of the housing will affect the operation. At the same time, the housing remains fixed in the same position during each operation, ensuring consistent operating conditions.

[0145] S202, the operating point of the circuit board is opposite to the active operating part of the operating device.

[0146] In the above embodiments, the active operating part of the operating device may have operating devices such as probes. By keeping the operating point relative to the active operating part of the operating device, it is easy for the active operating part to accurately contact the operating point when it moves. This connects the circuit board to the active operating part of the operating device to establish an electrical channel, enabling the operating device to send operating signals to the circuit board and receive response signals returned by the circuit board, so as to detect and evaluate the fault parameters of the circuit board.

[0147] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
