[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The first aspect of the present invention provides a PCB board 10, including at least two rigid regions 11 for mounting electronic components, the at least two rigid regions 11 including a first rigid region 111 and a second rigid region 112; at least one flexible region 12, the at least one flexible region 12 including a first flexible region 121, the first flexible region 121 being used to connect the first rigid region 111 and the second rigid region 112; the rigid region 11 and the flexible region 12 are integrally formed.

[0038] According to a first aspect embodiment of the PCB board 10, such as Figure 1-3 As shown, the first rigid region 111 and the second rigid region 112 are connected by the first flexible region 121. The PCB board 10 can be bent through the first flexible region 121, reducing the space occupied by the PCB board 10 and improving the flexibility of its layout. When the first rigid region 111 and the second rigid region 112 of the PCB board 10 are arranged in different areas, they can be connected through the first flexible region 121, eliminating the need for connecting wires and reducing the cost and layout difficulty of the PCB board 10. Simultaneously, the rigid region 111 and the flexible region 12 of the PCB board 10 are integrally formed, and the entire PCB board 10 is made of the same material, ensuring the signal transmission quality of the PCB board 10. In other words, the PCB board 10 of this embodiment, while ensuring signal transmission quality, reduces the space occupied by the PCB board 10, lowering its cost and reducing its layout difficulty.

[0039] Furthermore, the PCB board 10 may also include three rigid regions 11 and two flexible regions 12. The rigid regions 11 and flexible regions 12 are spaced apart, and the flexible regions 12 are connected between the two rigid regions 11. The PCB board 10 can be folded through the two flexible regions 12, reducing the space occupied by the PCB board 10 and improving the flexibility of the PCB board 10 layout. When the three rigid regions 11 of the PCB board 10 are arranged in different areas, they can be connected through the flexible regions 12, eliminating the need for connecting wire harnesses and reducing the cost and layout difficulty of the PCB board 10. At the same time, the rigid regions 11 and flexible regions 12 of the PCB board 10 are integrally formed structures, and the entire PCB board 10 is made of the same material. That is, while ensuring signal transmission quality, the PCB board 10 reduces the space occupied by the PCB board 10, reducing the cost and layout difficulty of the PCB board 10. Similarly, the PCB board 10 may also include four or more rigid regions 11 and multiple flexible regions 12 corresponding to the rigid regions 11, which will not be elaborated here.

[0040] In some embodiments, the thickness of the flexible region 12 is less than the thickness of the rigid region 11.

[0041] like Figure 1As shown, the thickness T of the flexible area 12 of the PCB board 10 is less than the thickness of the rigid area 11 of the PCB board 10, which enables the PCB board 10 to bend flexibly. It can be flexibly bent and arranged according to product usage requirements, adapting to various irregular shapes of product internal structures and effectively saving space. Compared with the PCB board 10 design with a fully rigid area 11 in related technologies, this solution can be bent into different shapes according to product requirements, improving the flexibility of product design, enabling a more compact layout of the PCB board 10 and electronic components, and improving the space utilization rate of the product.

[0042] In some embodiments, the first flexible region 121 may cause the projections of the first rigid region 111 and the second rigid region 112 in the thickness direction of the PCB board 10 to coincide.

[0043] like Figure 2 As shown, according to product usage requirements, when the first rigid area 111 and the second rigid area 112 of the PCB board 10 are arranged in the same area, the PCB board 10 can be bent through the first flexible area 121 between the first rigid area 111 and the second rigid area, so that the projections of the first rigid area 111 and the second rigid area 112 in the thickness direction of the PCB board 10 coincide, thereby reducing the space occupied by the PCB board 10, improving the flexibility of the PCB board 10 arrangement, adapting to the internal structure of various irregularly shaped products, and effectively saving space.

[0044] In some embodiments, the flexible region 12 is formed by a depth control process.

[0045] like Figure 1 As shown, the flexible area 12 of the PCB board 10 can be made using a depth-controlled process, allowing for localized depth-controlled cutouts on the PCB board 10. This enables the originally rigid PCB board to achieve a flexible bending effect in the thinned sections, creating both a rigid, non-bendable area and a flexible, bendable area within the PCB board 10. Furthermore, since the rigid area 11 and the flexible area 12 are integrally formed, there is no need to bind or connect them, reducing the impact of the transition area between the rigid area 11 and the flexible area 12 on the signal transmission quality of the PCB board 10 and simplifying the manufacturing process. In other words, the depth-controlled process for the flexible area 12 of the PCB board 10 reduces the space occupied by the PCB board 10 while ensuring signal transmission quality, thus lowering the cost and layout complexity of the PCB board 10.

[0046] In some embodiments, the wiring between the rigid region 11 and the flexible region 12 is continuous without transition.

[0047] like Figure 1-3As shown, the traces between the first rigid region 111, the first flexible region 121 and the second rigid region 112 of the PCB board 10 are continuous without transition, which further improves the signal transmission quality of the PCB board 10 and ensures the stability of the signal transmission of the PCB board 10.

[0048] In addition, the PCB board 10 may also include three rigid regions 11 and two flexible regions 12. The rigid regions 11 and flexible regions 12 are spaced apart, and the flexible regions 12 are connected between the two rigid regions 11. The traces between the rigid regions 11 and the flexible regions 12 are continuous without transitions, which can further improve the signal transmission quality of the PCB board 10 and ensure the stability of the signal transmission of the PCB board 10. Similarly, the PCB board 10 may also include four or more rigid regions 11 and multiple flexible regions 12 corresponding to the rigid regions 11, which will not be described in detail here.

[0049] In some optional embodiments, the ground lines on both sides of the signal lines of the PCB board 10 are shielded to achieve the shielding effect of the PCB.

[0050] A second aspect of the present invention provides an impedance adjustment system 100, applied to a PCB board 10 in any of the above embodiments, comprising: a capacitor 20 connected in parallel to the traces of the PCB board 10, wherein the capacitance value of the capacitor 20 is adaptively adjustable to achieve the adjustment of the trace impedance of the PCB board 10.

[0051] According to a second aspect of the present invention, the impedance adjustment system 100 includes a capacitor 20 connected in parallel to the traces of a PCB board 10. The capacitance value of the capacitor 20 is adaptively adjustable. That is, by adjusting the capacitance value of the variable capacitor 20, the trace impedance of the PCB board 10 connected in parallel with the capacitor 20 is changed. By adjusting the trace impedance of the PCB board 10, the reflection and distortion of the signal during transmission are reduced, making the signal voltage and current distribution on the transmission line of the PCB board 10 more uniform and stable, enhancing the anti-interference capability of the PCB board 10 when transmitting signals, and significantly improving the stability of signal transmission and the quality of the output signal of the PCB board 10.

[0052] In some embodiments, the impedance adjustment system 100 further includes a processor 30, which is connected to both the capacitor 20 and the PCB board 10, and is used to adjust the capacitance value of the capacitor 20 according to the signal characteristics of the PCB board 10.

[0053] like Figure 4 As shown, the processor 30 is connected to the capacitor 20, which is connected in parallel to the traces of the PCB board 10. The processor 30 can adjust the capacitance of the capacitor 20 according to the signal characteristics, thereby changing the trace impedance of the PCB board 10 connected in parallel with the capacitor 20, optimizing the signal quality, and enhancing the anti-interference capability of the rigid area 11 and the flexible area 12 of the PCB board 10.

[0054] In some embodiments, signal characteristics include amplitude characteristics and frequency characteristics of the signal.

[0055] Specifically, the processor 30 can adjust the capacitance value of the capacitor 20 according to the amplitude and frequency characteristics of the signal. This adjustment can be based on the signal characteristics of the input signal to the PCB board 10, or on the signal characteristics of both the input and output signals of the PCB board 10. This changes the trace impedance of the PCB board 10 connected in parallel with the capacitor 20, making the signal voltage and current distribution on the transmission line of the PCB board 10 more uniform and stable, enhancing the anti-interference capability of the PCB board 10 when transmitting signals, and significantly improving the stability of signal transmission and the quality of the output signal of the PCB board 10.

[0056] In some optional embodiments, the processor 30 adjusts the capacitance of the capacitor 20 according to the amplitude and frequency characteristics of the signal using an AI model algorithm, and dynamically adjusts the trace impedance of the PCB board 10 in real time, so that the signal quality transmitted by the traces of the PCB board 10 is always kept in the best state, enhancing the anti-interference capability of the trace signals of the PCB board 10, and making the PCB board 10 less susceptible to interference when transmitting signals.

[0057] In some alternative embodiments, such as Figure 4 As shown, the processor 30 in the impedance adjustment system 100 has signal feature detection, AI model algorithm, and bias voltage adjustment functions. The processor 30 analyzes the frequency and amplitude characteristics of the input and output signals of the PCB board 10 and generates signal feature values. The AI ​​model reads the signal features of the input and output signals, processes them using the AI ​​model algorithm, and generates a bias voltage adjustment strategy. The processor 30 adjusts the bias voltage of the variable capacitor 20 according to the bias voltage adjustment strategy. The variable capacitor 20 can change its capacitance value by applying a bias voltage, thereby changing the impedance of the PCB board 10 traces connected in parallel with the capacitor 20. The input signal is the signal output from the signal generation terminal, and the output signal is the signal received by the receiving terminal after transmission through the PCB board 10 traces.

[0058] A third aspect of the present invention provides an impedance adjustment method, applied to the impedance adjustment system 100 of any of the above embodiments, such as... Figure 5 As shown, the impedance adjustment method includes steps S1-S2, and the specific steps are as follows:

[0059] Step S1: Obtain the signal characteristics of the input signal of the PCB board 10.

[0060] Step S2: Adjust the capacitance value of capacitor 20 according to the signal characteristics to adjust the trace impedance of PCB board 10.

[0061] According to the impedance adjustment method of the third aspect of the present invention, the signal characteristics of the input signal of the PCB board 10 are obtained by the signal characteristic detection function. Based on the signal characteristics, the capacitance value of the capacitor 20 connected in parallel with the trace of the PCB board 10 is adjusted, thereby changing the trace impedance of the PCB board 10 connected in parallel with the capacitor 20. By adjusting the trace impedance of the PCB board 10, the reflection and distortion of the signal during transmission are reduced, making the signal voltage and current distribution on the transmission line of the PCB board 10 more uniform and stable, enhancing the anti-interference ability of the PCB board 10 when transmitting signals, and significantly improving the stability of signal transmission and the quality of output signal of the PCB board 10.

[0062] In some optional embodiments, the amplitude and frequency characteristics of the input signal of the PCB board 10 are obtained, and the capacitance of the capacitor 20 is adjusted according to the amplitude and frequency characteristics to adjust the trace impedance of the PCB board 10.

[0063] In some embodiments, the impedance adjustment method specifically includes: calculating the target impedance of the traces on the PCB board 10 based on signal characteristics; and adjusting the capacitance value of the capacitor 20 based on the target impedance.

[0064] Specifically, the signal characteristics of the input signal on the PCB board 10 are obtained through signal feature detection. Based on these characteristics, the target impedance of the traces on the PCB board 10 is calculated. The capacitance of the matching capacitor 20 is then adjusted to match the target impedance of the traces on the PCB board 10, making the final impedance of the traces on the PCB board 10 infinitely close to the target impedance. This enhances the anti-interference capability of the PCB board 10 during signal transmission, improves the stability of signal transmission, and enhances the quality of the output signal.

[0065] In some optional embodiments, an AI model algorithm is used to calculate the target impedance of the traces on the PCB board 10 based on the signal characteristics of the input signal. The capacitance value of the capacitor 20 is adjusted according to the target impedance to optimize the signal quality in real time, so that the signal quality transmitted by the PCB board 10 is always kept in the best state. This enhances the anti-interference capability of the PCB board 10 when transmitting signals, and improves the stability of product signal transmission and the quality of received signals.

[0066] In some embodiments, the impedance adjustment method specifically includes: determining the bias voltage adjustment amount based on the target impedance; and adjusting the capacitance value of capacitor 20 based on the bias voltage adjustment amount.

[0067] Specifically, the signal characteristics of the input signal of the PCB board 10 are obtained through the signal characteristic detection function. Based on the signal characteristics, the target impedance of the traces of the PCB board 10 is calculated. Based on the target impedance of the traces of the PCB board 10, the bias voltage adjustment amount is obtained, and the bias voltage applied to the variable capacitor 20 is controlled and adjusted, thereby changing the capacitance value of the variable capacitor 20. By changing the capacitance value of the bias capacitor 20, the trace impedance of the PCB board 10 connected in parallel with the bias capacitor 20 is changed, thereby achieving the purpose of adjusting the trace impedance of the PCB board 10.

[0068] In some embodiments, the impedance adjustment method further includes: acquiring the signal characteristics of the output signal of the PCB board 10; and adjusting the capacitance value of the capacitor 20 according to the difference between the signal characteristics of the output signal and the signal characteristics of the input signal.

[0069] Specifically, the signal characteristics of the input signal to PCB board 10 are obtained through signal feature detection. Based on these characteristics, the target impedance of the traces on PCB board 10 is calculated. The bias voltage adjustment amount is then determined based on the target impedance, and the bias voltage applied to variable capacitor 20 is adjusted accordingly, thereby changing the capacitance value of variable capacitor 20. Furthermore, the signal characteristics of the output signal to PCB board 10 are obtained through signal feature detection. Based on the difference between the output signal characteristics and the input signal characteristics, the capacitance value of capacitor 20 is further optimized, ensuring that the quality of the received output signal remains optimal and enhancing the signal anti-interference capability of PCB board 10.

[0070] In some embodiments, the impedance adjustment method specifically includes: adjusting the capacitance value of capacitor 20 when the difference between the signal characteristics of the output signal and the signal characteristics of the input signal is greater than or equal to a set threshold.

[0071] Specifically, the signal characteristics of the input signal on the PCB board 10 are obtained through the signal characteristic detection function. After changing the capacitance value of the variable capacitor 20 according to the signal characteristics, the capacitor 20 is further optimized when the difference between the signal characteristics of the output signal and the signal characteristics of the input signal is greater than or equal to a set threshold, thereby improving the system's operating efficiency while ensuring the quality of the output signal.

[0072] In some optional embodiments, the signal characteristics include the amplitude characteristics and frequency characteristics of the signal. When the difference between the signal characteristics of the output signal and the amplitude signal characteristics of the input signal is greater than or equal to a set threshold, the capacitor 20 is optimized and adjusted; or when the difference between the signal characteristics of the output signal and the frequency signal characteristics of the input signal is greater than or equal to a set threshold, the capacitor 20 is optimized and adjusted, thereby improving the system's operational efficiency while ensuring the quality of the output signal.

[0073] In some embodiments, the impedance adjustment method further includes performing a trace impedance optimization calculation on the PCB board 10 at regular intervals, that is, ensuring the output signal quality of the PCB board 10 while taking into account the system's operational efficiency.

[0074] In some alternative embodiments, such as Figure 6 As shown, the processor 30 in the impedance adjustment system 100 first analyzes the signal frequency and amplitude characteristics of the input signal. Then, it transmits the analyzed signal characteristics to the AI ​​model. After processing by the AI ​​model, a bias voltage adjustment strategy for the variable capacitor 20 is generated. This strategy controls and adjusts the bias voltage applied to the variable capacitor 20, thereby changing the capacitance value of the variable capacitor 20. By changing the capacitance value of the bias capacitor 20, the trace impedance of the PCB board 10 connected in parallel with the bias capacitor 20 is changed, achieving the purpose of PCB board 10 trace impedance adjustment. By adjusting the PCB board 10 trace impedance, signal reflection and distortion during transmission are reduced, making the signal voltage and current distribution on the transmission line of the PCB board 10 more uniform and stable. This reduces the impact of noise and interference on the signal quality of the PCB board 10, achieving the goal of optimizing the output signal quality. Furthermore, the optimized output signal is synchronously fed back to the processor 30 in the impedance adjustment system 100. The processor 30 uses an AI algorithm to synchronously detect the signal frequency and amplitude characteristics of the output signal. If the detected deviation between the output signal characteristics and the input signal characteristics is greater than or equal to a set threshold, the processor 30 adjusts the bias voltage regulation strategy of the variable capacitor 20 in real time through the autonomous learning and decision-making characteristics of the AI ​​model algorithm until the signal characteristic deviation between the output signal and the input signal is within the set threshold range, thereby achieving real-time optimization of the output signal quality, keeping the output signal quality at its best, and improving the anti-interference capability of the signal when it is transmitted on the PCB board 10.

[0075] A fourth aspect of the present invention provides a controller, including a housing and a PCB board 10 of any of the above embodiments, or including a housing and an impedance adjustment system 100 of any of the above embodiments, wherein the PCB board 10 is disposed within the housing.

[0076] The controller according to a fourth aspect embodiment of the present invention, such as Figure 2As shown, the PCB board 10 is housed within a controller housing. The first rigid region 111 and the second rigid region 112 of the PCB board 10 are connected by a first flexible region 121. The PCB board 10 can be bent via the first flexible region 121, reducing its space footprint within the controller and improving its layout flexibility. The rigid region 111 and the flexible region 122 of the PCB board 10 are integrally formed, ensuring signal transmission quality while reducing the space occupied by the PCB board 10 within the controller and enhancing layout flexibility. Furthermore, the impedance adjustment system 100 further enhances the anti-interference capability of the PCB board 10 during signal transmission, improving the stability of the controller signal transmission and the quality of the output signal.

[0077] Specifically, the PCB board 10 can be folded at different angles according to the controller's usage and shape design requirements, making the design of the PCB board 10 match the controller's usage and installation needs. The shape of the PCB board 10 does not need to be considered during controller design, making the entire controller design more flexible.

[0078] In some alternative embodiments, the controller can be a domain controller on the vehicle. The PCB board 10 is arranged within the same domain controller, and its overall volume can be reduced by bending and overlapping. This simultaneously reduces the space required for mounting the domain controller and the vehicle space occupied when the domain controller is installed. Bending the PCB board allows it to adapt to domain controllers of different shapes and spatial layouts, making the domain controller design more compatible with installation and usage requirements. The rigid area 11 and flexible area 12 of the PCB board 10 are integrally formed, and combined with the impedance adjustment system 100, the domain controller ensures signal transmission quality while saving costs and offering greater flexibility in vehicle installation.

[0079] The fifth aspect of the present invention provides a control system, including a first controller, a second controller and a PCB board 10 of any of the above embodiments, or including a first controller, a second controller and an impedance adjustment system 100 of any of the above embodiments. The first controller and the second controller are connected through a first flexible area 121, a first rigid area 111 is disposed in the first controller, and a second rigid area 112 is disposed in the second controller.

[0080] The control system according to the fifth aspect embodiment of the present invention, such as Figure 3As shown, in the control system, the first rigid area 111 is located within the first controller, and the second rigid area 112 is located within the second controller. The first controller and the second controller are connected through the first flexible area 121, which eliminates a large number of cross-controller wiring harnesses, reducing the wiring cost and complexity of the control system. The rigid area 11 and the flexible area 12 of the PCB board 10 are integrally formed, which reduces the space occupied by the PCB board 10 in the controller while ensuring the signal transmission quality of the control system, thus improving the flexibility of the control system layout. In addition, the impedance adjustment system 100 can also change the trace impedance of the PCB board 10 connected in parallel with the capacitor 20 by adjusting the capacitance value of the variable capacitor 20. By adjusting the trace impedance of the PCB board 10, the reflection and distortion of the signal during transmission are reduced, making the signal voltage and current distribution on the transmission line of the PCB board 10 more uniform and stable, further enhancing the anti-interference capability of the PCB board 10 when transmitting signals, and improving the stability of the control system signal transmission and the quality of the output signal.

[0081] In some optional embodiments, both the first controller and the second controller can be domain controllers on the vehicle. A first rigid region 111 is disposed within the first domain controller, and a second rigid region 112 is disposed within the second domain controller. The first and second domain controllers are connected via a first flexible region 121, eliminating the need for numerous wiring harnesses connecting different domain controllers and reducing the wiring cost and complexity of the control system. The rigid region 11 and flexible region 12 of the PCB board 10 are integrally formed, and combined with the impedance adjustment system 100, the domain control system ensures signal transmission quality while saving costs and offering greater flexibility in vehicle installation.

[0082] In some alternative embodiments, the control system may include three or more controllers, with the rigid area 11 of the PCB board 10 disposed within each controller. The controllers can be connected to each other through the flexible area 12 of the PCB board 10, so that the domain control system can save costs and make the installation on the vehicle more flexible while ensuring signal transmission quality.
