[0037] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the accompanying drawings.

In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0039] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0041] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0042] In the related art, when operating the circuit board installed in the controller to locate and operate on the specific fault location and fault circuit on the circuit board, the circuit board needs to be forcibly removed from the housing of the controller. Generally, the circuit board and the housing in the controller are fixedly connected by means of bonding or welding, etc. When the circuit board is forcibly removed, it will cause damage to the circuit board and increase the steps of operating the circuit board, resulting in low operation efficiency.

[0043] When a circuit board failure occurs during the use of the controller provided by the embodiment of the present application, when the circuit board is connected to the housing, the operation information of the operation points on the circuit board can be directly obtained through the operation device, and then the operation information can be collected and analyzed subsequently through the operation device, so as to accurately locate the specific failure position and failure circuit on the circuit board in a timely manner, improve the operation efficiency of the circuit board, and ensure the structural integrity of the circuit board.

[0044] Referring to Figure 1 and Figure 2 , the embodiment of the present application provides a controller, and the controller includes:

[0045] A housing 100 and a cover plate 200, one side of the housing 100 has an opening, and the cover plate 200 is connected to the housing 100 and can expose the opening;

[0046] A circuit board 300, the circuit board 300 is fixed to the housing 100, and a plurality of operation points 303 of the circuit board 300 converge on the side of the circuit board 300 facing the opening, that is, all the operation points 303 of the circuit board 300 are formed on the side of the circuit board 300 facing the opening.

[0047] In this embodiment, the housing 100 and the cover plate 200 are connected relatively to form the outer shell of the controller, and the outer shell can protect the components such as the circuit board inside it.

[0048] See Figure 1 , a receiving cavity is formed inside the housing 100, and one side of the housing 100 has an opening. For example, when the controller is installed, the housing 100 has an opening facing downwards or upwards, and the circuit board 300 can be conveniently and quickly installed in the receiving cavity inside the housing 100 through this opening. For example, the circuit board 300 is installed in the housing 100 by means of bonding or welding, etc., to ensure the stability of the installation of the circuit board 300.

[0049] In this embodiment, one side of the circuit board 300 can be fixed inside the housing 100, the other side of the circuit board 300 can face the opening on the housing 100, and the cover plate 200 is detachably connected to this opening, so that the side surface of the circuit board 300 facing the opening can be exposed when the cover plate 200 is detached from the housing 100; and there are a plurality of operation points 303 on the side of the circuit board 300 facing the opening, so that the circuit board 300 can be operated through the operation device without removing the circuit board 300.

[0050] In this embodiment, the operating point 303 can be a test point of the circuit board 300, so as to facilitate the testing of electrical faults of the circuit board 300 through the operating point 303. The operating point 303 can also be an installation point for fasteners such as mounting bolts, so as to facilitate the connection of the circuit board 300 to other mechanisms. The operating point 303 can also be a plugging point for plugging and unplugging devices such as fuses, so as to improve the connection convenience of the plugging and unplugging devices on the circuit board 300.

[0051] In some embodiments, the cover plate 200 can be openably connected to the opening. It can be that the cover plate 200 is detachably connected to the opening. For example, the cover plate 200 is connected to the opening by bolts or buckles, so as to facilitate the disassembly and assembly of the cover plate 200; it can also be that the cover plate 200 is rotatably connected to the opening. For example, the cover plate 200 is connected to the opening by a rotating shaft or an opening and closing member, so as to facilitate the flexible opening and closing of the cover plate 200.

[0052] It should be noted that when the cover plate 200 opens the opening to expose the multiple operating points 303 on the circuit board 300, the cover plate 200 can completely expose the opening, or can also expose a part of the opening, as long as the multiple operating points 303 on the circuit board 300 can be exposed. Similarly, when the cover plate 200 is connected to the opening to cover the opening, it can be that part or all of the cover plate 200 covers the opening, or it can also be that the cover plate 200 only covers a part of the opening, as long as the multiple operating points 303 on the circuit board 300 can be covered.

[0053] In a specific embodiment, the operating device performs test 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 line problems on the circuit board 300 to be operated, not only can it determine whether the circuit board 300 to be operated is qualified, but also can accurately judge the fault points on the circuit board 300 to be operated.

[0054] In this embodiment, since the cover plate 200 can expose the surface of the circuit board 300 facing the opening when it is disassembled or flipped from the housing 100, when operating on the multiple operating points 303 on the circuit board 300 with the circuit board 300 fixed to the housing 100, the operating points 303 are located in a space that is easy to expose, and the operating process will not damage the structure of the circuit board 300 itself. For example, only the cover plate 200 of the controller can be disassembled or flipped to expose the operating area of the circuit board 300 to be operated. The operating area is provided with multiple operating points 303, and then the housing 100 of the controller in which the circuit board 300 to be operated is fixed is directly fixed. That is, the operation of the circuit board 300 can be realized without disassembling the circuit board 300 from the housing 100.Figure 2 and Figure 3 As shown, it avoids the damage to the circuit board 300 caused by disassembling and assembling the circuit board 300 from the housing 100, and ensures the structural integrity of the circuit board 300.

[0055] After the operation of the circuit board 300 in the controller is completed, the cover plate 200 can be installed at the opening of the housing 100 again to ensure the structural integrity of the controller. When the controller is installed, the cover plate 200 can be at the bottom of the controller, that is, as the bottom plate of the controller; or the cover plate 200 can be at the top of the controller, that is, as the top plate of the controller.

[0056] The controller provided by the embodiment of the present application can directly obtain the operation information of the operation point 303 on the circuit board 300 through the operating device without destroying the connection relationship between the circuit board 300 and the housing 100, and then complete the collection of operation information and subsequent analysis through the operating device, improving the operation efficiency of the circuit board 300.

[0057] In one embodiment, the circuit board 300 is fixedly connected to the housing 100 in a non-detachable manner;

[0058] When the opening is exposed by the cover plate 200, the operation point 303 of the circuit board 300 can be operated.

[0059] In the above embodiment, the non-detachable connection means that it cannot be separated non-destructively after connection. For example, the circuit board 300 is fixedly connected to the housing 100 by welding or gluing, etc., to realize the irreversible connection between the circuit board 300 and the housing 100, so that the circuit board 300 cannot be disassembled from the housing 100 without damage.

[0060] The non-detachable 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 operation efficiency of operating the circuit board 300 through the operation point 303. When the circuit board 300 fails, the operation point 303 on the circuit board 300 can be directly detected through the exposed opening, ensuring the detection efficiency and reducing the maintenance difficulty.

[0061] In one embodiment, a plurality of operation points 303 are located at the corner positions on the side of the circuit board 300 facing the opening.

[0062] In the above embodiment, 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, and the operation points 303 are concentrated in the local area of the side of the circuit board 300 facing the opening. For example, multiple operation points 303 are located at the corner positions of the side of the circuit board 300 facing the opening. This can avoid excessive dispersion of multiple operation points 303. On the one hand, it is convenient for the operating device of the operating device to align and contact with the operation point 303, thereby 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.

[0063] In a specific embodiment, see Figure 2 The circuit board 300 is arranged in a square shape, and a plurality of operating points 303 are located in the operating area in the upper left corner of the circuit board 300. The range of the operating area can be Figure 2 As shown in the dotted box in FIG, when the operating device is only opposite to the operating area in the upper left corner of the circuit board 300, the circuit board 300 can be fully operated, thereby ensuring the efficiency of the operation.

[0064] In one embodiment, the plurality of operating points 303 are located in a plurality of sub-regions on a side of the circuit board 300 facing the opening, so that the operating points 303 are close to corresponding operated components, thereby improving operating efficiency.

[0065] In one embodiment, the operation points 303 are concentrated in the operation area on one side of the circuit board 300, which helps to divide the circuit board 300 into multiple functional modules, such as 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 a simulation 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.

[0066] In one embodiment, the plurality of operating points 303 are distributed on a side of the circuit board 300 facing the opening.

[0067] In the above embodiment, 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 operating point 303 with the operating device, and stress will be generated at the operating point 303 when the operating device contacts the operating point 303; the multiple operating points 303 on one side of the circuit board 300 are evenly distributed, which can reduce or even avoid the problem of uneven force on the circuit board 300 during operation, thereby ensuring the structural integrity of the circuit board 300.

[0068] In this embodiment, there is a spacing distance between the operating point 303 and the edge of the circuit board 300, and the spacing distance can be greater than or equal to 5 mm to prevent damage to the circuit board 300 caused by the force on the edge of the circuit board 300 during operation.

[0069] In this embodiment, the operating point 303 can be an electrical test point, and there is a minimum spacing between two adjacent operating points 303, and the minimum spacing can be greater than or equal to 2 mm to avoid interference or short circuit between adjacent operating points 303 during operation.

[0070] In one embodiment, referring to Figure 1 , a support column 101 is provided in the housing 100, and the side of the circuit board 300 facing away from the opening is fixed to the support column 101.

[0071] 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, which can facilitate the operation of a plurality of operating points 303 on the other side of the circuit board 300 through the opening while ensuring the stability of the circuit board 300.

[0072] In the above embodiment, one side of the circuit board 300 to be operated is fixed inside the housing 100 through 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, thus ensuring the stability and reliability of the circuit board 300; while the other side of the circuit board 300 to be operated faces the detachable cover plate 200, and operating points 303 can be provided 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 realized only when the cover plate 200 is removed.

[0073] In some embodiments, the circuit board 300 has a high-speed area and an operation area. The high-speed area is used to set high-speed devices, and a plurality of operating points 303 are located in the operation area.

[0074] In the above embodiment, at least a part of the area on the side 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 setting high-speed devices such as high-speed processors and high-speed memories, 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.

[0075] Referring to Figure 2 , the operation area can centrally set the operating points 303, that is, concentrate the operating points 303 into a non-high-speed area to avoid contacting high-speed devices such as high-speed lines; it is convenient to effectively operate and debug the circuit board 300, improving the efficiency and quality of the operation.

[0076] In some embodiments, the circuit board 300 includes at least one inner layer, a first outer layer and a second outer layer disposed on both sides of the inner layer. The inner layer is used to arrange high-speed signal lines. A plurality of operation points 303 are located on the first outer layer, and the second outer layer is fixed to the housing 100;

[0077] Among them, the projections of the plurality of operation points 303 on the inner layer are offset from the high-speed signal lines.

[0078] In the above embodiments, the circuit board 300 forms a multi-layer structure through one or more inner layers in cooperation with the first outer layer and the second outer layer. The multi-layer structure allows more circuit components and lines to be arranged in a limited space, improving the integration of the circuit board 300 and enabling the circuit board 300 to implement more complex functions. Electrical connections can be made between different layers of the circuit board 300 through vias and other means to reduce interference between signals, improve the transmission quality and stability of signals, and thus enhance the overall performance of the circuit.

[0079] Moreover, the shielding effect of the inner layer can reduce the influence 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.

[0080] The settings of the first outer layer and the second outer layer can increase the heat dissipation area of the circuit board 300, help dissipate the heat generated during the operation of the circuits in the circuit board 300, and improve the reliability of the circuit. At the same time, the outer layer also facilitates the maintenance and repair of the circuit board, and facilitates the setting of the operation points 303 and the troubleshooting of faults.

[0081] When a fault occurs in the circuit board, various fault parameters of the circuit can be quickly obtained through the operation points 303 on the first outer layer, which is convenient for fault location and diagnosis and provides an accurate basis for maintenance.

[0082] Fixing the second outer layer to the housing 100 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.

[0083] In the above embodiments, high-speed signal lines are very sensitive to the electromagnetic environment. If the projections of the operation points 303 overlap with the high-speed signal lines, it may cause the interference signals introduced by the operation points 303 to affect the transmission quality of the high-speed signals, or even cause signal errors. By offsetting the operation points 303 from the high-speed signal lines, the mutual interference between the operation points 303 and the high-speed signals can be effectively reduced, the purity and stability of the high-speed signals are improved, and the normal operation of the system is ensured.

[0084] In one embodiment, the controller further includes a heat conducting member disposed between the support post 101 and the circuit board 300.

[0085] In the above embodiment, electronic devices are provided on the side of the circuit board 300 facing away from the opening, and the electronic devices are opposite to the support posts 101, so that the heat conducting member is clamped between the electronic devices and the support posts 101.

[0086] The heat conducting member can effectively transfer the heat generated by the electronic devices on the circuit board 300 to the support posts 101, and then dissipate it to the external environment through the housing 100 or other heat dissipation structures, improving the heat dissipation efficiency of the controller, helping to reduce the operating temperature of the circuit board 300 and the electronic devices thereon, and being able to extend the service life of the circuit board 300 and the electronic devices.

[0087] In one embodiment, the controller further includes an adhesive member, and the circuit board 300 is fixed to the support post 101 through the adhesive member.

[0088] In the above embodiment, the adhesive member can quickly and simply fix the circuit board 300 to the support post 101 in 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 post 101.

[0089] In one embodiment, the adhesive member can be an adhesive member with good heat conduction performance such as thermal conductive glue. The adhesive member can effectively transfer the heat generated by the circuit board 300 to the support post 101, and then dissipate it to the external environment through the housing 100, improving the heat dissipation efficiency of the controller.

[0090] In one embodiment, refer to Figure 3 , a fixing structure 102 is provided on the housing 100, and the fixing structure 102 is configured to be fixedly connected to the operating device.

[0091] In the above embodiment, when operating on the circuit board 300 of the controller, the operating point 303 can be contacted through the operating device to perform operation analysis on the circuit board 300 to be operated. The fixing structure 102 ensures the firm connection between the housing 100 and the operating device, preventing the circuit board 300 from shaking or displacing due to unstable connection during the operation, and improving the stability of the operation and the accuracy of the operation result.

[0092] In one embodiment, the operating device further includes a carrier 5. The carrier 5 has a plurality of carrier posts, and the carrier posts are configured to support the housing 100. For example, fixing blocks are provided at the corners of the housing 100, and the fixing blocks and the carrier posts are connected and fixed through locking components such as pins and screws. The carrier 5 provides a stable support for the housing 100, ensuring the stability of the entire operation process.

[0093] In some embodiments, refer toFigure 2 and Figure 3 On the circuit board 300, a mating point 301 is provided. The mating point 301 and a plurality of operating points 303 are located on the same side of the circuit board 300.

[0094] The mating point 301 is configured to be connected to a connection point 11 on the operating device, and the operating device is used to operate a plurality of operating points 303 on the circuit board 300.

[0095] In the above embodiment, the mating point 301 on the circuit board 300 cooperates with the connection point 11 on the operating device, so that the detachable connection of the operating device to the circuit board 300 to be operated can be realized. For example, the mating point 301 can be a hook or a buckle, and the connection point 11 can be a buckle or a hook. The detachable connection of the operating device to the circuit board 300 to be operated is realized through the snap-fit between the buckle and the hook; the mating point 301 has a first threaded hole, or the connection point 11 is a connection block with a second threaded hole. The locking member realizes the detachable connection of the operating device to the circuit board 300 to be operated through the locking fit between the first threaded hole and the second threaded hole, which can not only ensure the stability of the operation when the circuit board 300 is installed on the housing 100, but also facilitate the disassembly of the operating device from the circuit board 300 to be operated.

[0096] In some embodiments, referring to Figure 5 , a positioning hole 302 is provided on the circuit board 300. The positioning hole 302 and a plurality of operating points 303 are located on the same side of the circuit board 300.

[0097] The positioning hole 302 is configured to be embedded and cooperate with a positioning post 12 on the operating device, and the operating device is used to operate a plurality of operating points 303 on the circuit board 300.

[0098] In the above embodiment, when connecting the operating device to the circuit board 300 to be operated, the positioning post 12 on the connecting member 1 in the operating device can be first aligned with the positioning hole 302 on the circuit board 300 to be operated. The embedded fit between the positioning post 12 and the positioning hole 302 provides precise positioning for the installation of the operating device on the circuit board 300 to be operated, ensures the position accuracy of the circuit board 300 to be operated during the operation process, and thus improves the operation efficiency of the circuit board 300.

[0099] In one embodiment, the controller is a domain controller.

[0100] In the above embodiments, since the domain controller has more complex functions and higher performance requirements, a failure of the circuit board in the domain controller will have a greater impact on the operation of the entire application system (such as a vehicle system). Timely and accurately locating the specific failure location and faulty circuit on the circuit board will significantly improve the performance and reliability of the domain controller. At the same time, directly performing failure operations on the circuit board inside the housing without disassembling the circuit board can meet the requirements of the complex circuit structure and failure location of the domain controller, ensuring the operation and maintenance efficiency of the domain controller.

[0101] In one embodiment, referring to Figures 4 to 5 , the operating device for operating the circuit board 300 includes:

[0102] A connector 1, on which a guide member 2 is provided, and the connector 1 is configured to be connected to the circuit board 300 to be operated;

[0104] The operating frame 31 can move closer to or away from the circuit board 300 to be operated along the guide member 2, so that the operating device 32 contacts or separates from the circuit board 300 to be operated.

[0105] In this embodiment, the connector 1 can be a connecting plate or connecting platform of the operating device, so as to facilitate connecting to the circuit board 300 to be operated while carrying the operating assembly 3, and ensure the structural compactness between the operating device and the circuit board 300 to be operated during operation.

[0106] In one embodiment, referring to Figure 6 , the connector 1 has four corners. A set of opposite corners are provided with positioning posts 12 to facilitate the precise positioning of the operating device on the circuit board 300 to be operated; the other set of opposite corners are provided with connection points 11 to facilitate the detachable connection of the operating device on the circuit board 300 to be operated.

[0107] Referring to Figure 4 and Figure 6 , when the operating device operates on the circuit board 300 to be operated, the connector 1 can be connected to the circuit board 300 to be operated to form an integral body of the operating device and the circuit board 300 to be operated, ensuring the relative accuracy between the operating device and the circuit board 300 to be operated.

[0108] Referring to Figure 4, the operating device 32 is disposed on the operating frame 31, and the operating frame 31 is movably connected to the connecting member 1 through the guiding member 2; the guiding member 2 can extend in a direction perpendicular to the circuit board 300 to be operated, so that when the operating frame 31 approaches or moves away from the circuit board 300 to be operated along the guiding member 2, the operating frame 31 can drive the operating device 32 to approach or move away from the circuit board 300 to be operated together.

[0109] When the operating frame 31 drives the operating device 32 to approach the circuit board 300 to be operated together, the operating device 32 can contact the operating point 303 on the circuit board 300 to be operated after gradually approaching the circuit board 300 to be operated, so as to perform operation analysis on the circuit board 300 to be operated through the operating device 32. The guiding member 2 can provide a guiding path for the movement of the operating device 32, prevent the operating device 32 from shifting during the process of approaching the circuit board 300 to be operated, ensure the position accuracy of the movement of the operating device 32, and improve the operation precision and efficiency of the operating device for the circuit board 300 to be operated.

[0110] After the operating device 32 finishes operating on the circuit board 300 to be operated, the operating frame 31 can drive the operating device 32 to move away from the circuit board 300 to be operated together, realizing the separation of the operating device 32 from the circuit board 300 to be operated, and facilitating the operation on the replaced circuit board 300 to be operated again. Through the connection and fixation between the connecting member 1 and the circuit board 300 to be operated and the cooperation of the movement of the operating frame 31 and the operating device 32 along the guiding member 2, the precise positioning between the operating device and the circuit board 300 to be operated is ensured. Moreover, the assembly between the operating device and the circuit board 300 to be operated is simple, improving the convenience and efficiency of the operation.

[0111] In some embodiments, refer to Figure 1 and Figure 2 , one end of the guiding member 2 is fixed to the connecting member 1, and the other end of the guiding member 2 has a stop portion 21;

[0112] The operating frame 31 includes a movable plate 311, and the movable plate 311 is sleeved on the guiding member 2 and is located between the connecting member 1 and the stop portion 21.

[0113] In the above embodiment, the guiding member 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 when the movable plate 311 drives the operating device 32 to approach or move away from the circuit board 300 to be operated.

[0114] The stop portion 21 is located at one end of the guide member 2 away from the connecting member 1. For example, the stop portion 21 is provided at the top end of the guide member 2, which limits the movement range of the movable plate 311, can prevent the movable plate 311 from moving excessively and detaching from the guide member 2, and provides an effective movement range for the movable plate 311.

[0115] In some embodiments, referring to Figure 1 and Figure 2 , a bearing 312 is provided on the movable plate 311, and the movable plate 311 is sleeved and fitted with the guide member 2 through the bearing 312.

[0116] In the above embodiments, the bearing 312 can be a sliding bearing or a linear bearing. The setting of the bearing 312 can reduce the frictional resistance when the movable plate 311 moves on the guide member 2, thereby reducing the structural wear caused by friction; moreover, the installation of the bearing 312 can ensure the accuracy and stability of the movement trajectory of the movable plate 311 on the guide member 2, thereby improving the operation accuracy of the operating device 32 for the circuit board 300 to be operated.

[0117] In some embodiments, referring to Figure 4 and Figure 6 , the operation frame 31 includes an elastic member 313, and the elastic member 313 is provided between the movable plate 311 and the connecting member 1; or,

[0118] The elastic member 313 is provided between the movable plate 311 and the stop portion 21.

[0119] In the above embodiments, referring to Figure 4 , when the elastic member 313 is provided between the movable plate 311 and the connecting member 1, when the movable plate 311 drives the operating device 32 to approach the circuit board 300 to be operated together, the elastic member 313 will be compressed. At the same time, the elastic member 313 can absorb the impact and vibration generated when the movable plate 311 moves or is subjected to an external force, thereby playing a role in buffering and shock absorption and ensuring the stability of the movable plate 311 during the movement; after the operation of the operating device 32 on the circuit board 300 to be operated is completed, the elastic potential energy accumulated after the compression of the elastic member 313 can push up the movable plate 311, realizing the reset of the operating device 32 and the movable plate 311, and realizing the separation of the operating device 32 from the circuit board 300 to be operated.

[0120] When the elastic member 313 is disposed between the movable plate 311 and the stop portion 21, when the movable plate 311 drives the operating device 32 to approach the circuit board 300 to be operated together, the elastic member 313 will be stretched. At the same time, the elastic member 313 can buffer the impact and vibration generated when the movable plate 311 moves or is subjected to an external force, ensuring the stability of the movable plate 311 during the movement; after the operation of the operating device 32 on the circuit board 300 to be operated is completed, the elastic potential energy accumulated after the elastic member 313 is stretched can pull up the movable plate 311, realizing the reset of the operating device 32 and the movable plate 311, and realizing the separation of the operating device 32 from the circuit board 300 to be operated.

[0121] In some embodiments, referring to Figure 4 , the operating device further includes a driving member 4. The operating frame 31 includes an operating frame 314. The operating frame 314 is connected to the movable plate 311 and extends toward the driving member 4;

[0122] The driving member 4 is configured to drive the operating frame 314 to act, so as to drive the movable plate 311 to move along the guide member 2.

[0123] In the above embodiment, the driving member 4 can be driven manually, electrically or by starting. The driving head of the driving member 4 applies a driving force to the operating frame 314, so that the operating frame 314 drives the movable plate 311 to move together. By means of the operating frame 314 as a bridge, the efficiency of the driving member 4 driving the movable plate 311 to move can be improved.

[0124] In one embodiment, the driving member 4 can have positioning and locking functions. For example, the driving head of the driving member 4 adsorbs to the operating frame 314, and by controlling the moving stroke of the driving head, the moving distance of the movable plate 311 can be controlled.

[0125] In one embodiment, the operating frame 314 has a plurality of connecting arms connected to the movable plate 311 to improve the firmness of the connection between the operating frame 314 and the movable plate 311, and ensure the stability of the driving member 4 driving the movable plate 311 to move through the operating frame 314.

[0126] In some embodiments, referring to Figure 2 , Figure 4 and Figure 6 , the operating frame 31 includes a movable plate 311. 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 connecting member 1. The probe 322 is fixed to the movable plate 311 and is electrically connected to the operating plate 321;

[0127] The probe 322 is used to contact the operating point 303 on the circuit board 300 to be operated.

[0128] In the above embodiments, the probe 322 is directly fixed to the movable plate 311 and electrically connected to the operation board 321, simplifying the transmission path of the operation signal obtained by the probe 322, reducing the possibility of signal attenuation and interference, and thus improving the operation speed and accuracy.

[0129] In this embodiment, referring to Figure 2 and Figure 4 , when the operating device operates on 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 operation board 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.

[0130] In one embodiment, the operation board 321 and the movable plate 311 are arranged at intervals. For example, the operation board 321 is arranged on the side of the movable plate 311 away from the circuit board 300 to be operated. By setting the position of the operation board 321 away from the circuit board 300 to be operated, on the one hand, the influence of external interference on the operation result is reduced, further improving the operation accuracy; on the other hand, the guide member 2 can be avoided, providing space for the movement of the movable plate 311.

[0131] In the above embodiments, the probe 322 can pass through the through hole on the connecting member 1, or the probe 322 contacts the operation point 303 on the circuit board 300 to be operated after passing through the outer peripheral side of the connecting member 1, both of which can realize the positioning and operation of the fault on the circuit board 300 to be operated.

[0132] In some embodiments, referring to Figure 4 and Figure 6 , the operating device 32 includes a flexible connecting member 323. One end of the flexible connecting member 323 is connected to the operation board 321, and the other end of the flexible connecting member 323 is connected to the probe 322.

[0133] In the above embodiments, the flexible connecting member 323 can be a bonding wire or a cable. By connecting each pin on the operation board 321 to the probe 322 on the movable plate 311 through the flexible connecting member 323, it can not only absorb the installation error between the operation board 321 and the probe 322, but also help to ensure the stable connection between the operation board 321 and the probe 322, ensuring the reliability of signal transmission.

[0134] Moreover, the flexible connecting member 323 has the characteristics of being easily bent and stretchable, making the installation of the flexible connecting member 323 more flexible and convenient. During the maintenance of the operating device, if it is necessary to replace or adjust the operation board 321 or the probe 322, the flexible connecting member 323 can also provide more operating space, reducing the difficulty of maintenance.

[0135] An embodiment of the present application provides a vehicle, and the vehicle includes the above-mentioned controller.

[0136] In the above embodiment, the controller can be an autonomous driving controller, a power controller, a chassis controller, or a cockpit controller in the vehicle.

[0137] The controller of the vehicle includes a housing 100 and a cover plate 200. One side of the housing 100 has an opening, and the cover plate 200 is detachably connected to the opening; a circuit board 300 is fixed to the housing 100. A plurality of operation points 303 are provided on the side of the circuit board 300 facing the opening. Without damaging the connection relationship between the circuit board 300 and the housing 100, the operation information of the operation points 303 on the circuit board 300 can be directly obtained through an operation device, and then the operation information collection and subsequent analysis can be completed through the operation device, improving the operation efficiency of the circuit board 300.

[0138] An embodiment of the present application provides an operation method for a circuit board in a controller, and the operation method includes:

[0139] S101, exposing the opening of the housing through the cover plate to expose a plurality of operation points gathered on one side of the circuit board.

[0140] In the above embodiment, during the use of the controller, the cover plate covers the side where the operation points of the circuit board are located, which can play a role in protecting the circuit board and the internal structure of the housing.

[0141] When the controller fails and it is necessary to operate on the circuit board in the controller, after removing or flipping the cover plate from the housing, the originally blocked operation points are exposed, providing a physical space for the operation device to directly contact the operation points, enabling the subsequent operations to proceed smoothly.

[0142] S102, bringing an operation device into contact with the plurality of operation points to operate on the circuit board in the housing.

[0143] During the process of operating on the circuit board in the controller, the operation device can establish an electrical connection with the circuit board by contacting the plurality of operation points to achieve signal input and output. The operation device can send an operation signal to the circuit board and receive a response signal returned by the circuit board at the same time, so as to detect and evaluate the fault signal of the circuit board.

[0144] In the above embodiments, the two steps of removing the cover plate to expose the operation point and the operation device contacting the operation point cooperate with each other to form a complete pre-operation preparation and operation execution process. Removing the cover plate provides conditions for the operation device to contact the operation point, and the operation device contacting the operation point realizes the actual operation on the circuit board. The two work together to make the whole operation process smoother and more efficient.

[0145] In some embodiments, before exposing the opening of the housing through the cover plate to expose a plurality of operation points gathered on one side of the circuit board, it further includes;

[0146] S201, fixing the housing to the fixed part of the operation device.

[0147] In the above embodiments, fixing the housing to the fixed part of the operation device constructs a stable reference platform for the whole operation process. During the operation, the circuit board and its housing will not shake or displace, ensuring that the relative position between the operation device and the circuit board always remains stable, and improving the accuracy and reliability of the operation result.

[0148] Moreover, after the housing is fixed, the operator can operate and debug the operation device more conveniently without worrying that the movement of the housing will affect the operation process. At the same time, the housing is fixed at the same position each time of operation, so that the operation conditions can be kept consistent.

[0149] S202, the operation points of the circuit board are opposite to the movable operation part of the operation device.

[0150] In the above embodiments, the movable operation part of the operation device can have operation devices such as probes. By keeping the operation point opposite to the movable operation part of the operation device, it is convenient for the movable operation part to accurately contact the operation point when moving, and then connect the circuit board with the movable operation part of the operation device to establish an electrical channel, so that the operation device can send operation signals to the circuit board and receive the response signals returned by the circuit board to detect and evaluate the fault parameters of the circuit board.
