The signal acquisition module 1 is connected to the button circuit on the car door panel via an electrical interface. The adapter switching module 3 is fixedly connected to different models of car door panels via a mechanical interface. The detection power supply module 4 supplies power to the car door panel via a power interface. The signal acquisition module 1, adapter switching module 3, and detection power supply module 4 transmit the acquired signal, adapter signal, and power status signal to the data processing module 2 for processing. The data processing module 2 then transmits the processed signal to the display unit 5 and the voice prompt module 6 to achieve the output function.

[0021] The specific structure of the adaptation switching module 3 is as follows: Figure 2As shown, the system includes a mechanical positioning unit 7 and an electrical connection unit 8. The mechanical positioning unit 7 has a threaded structure and achieves a fixed connection by rotating to engage with the mounting holes in the car door panel. The electrical connection unit 8 consists of a set of elastic contacts that directly connect to the circuit interface on the car door panel. Both the mechanical positioning unit 7 and the electrical connection unit 8 transmit positioning signals and connection status signals to the data processing module 2 via internal wires. The mechanical positioning unit 7 and the electrical connection unit 8 are arranged vertically, with the mechanical positioning unit 7 located above and serving as the main fixing component, while the electrical connection unit 8 is located below and its elastic design ensures reliable contact with the door panel circuit interface.

[0022] The signal acquisition module 1 includes a key path detection unit and a key feedback detection unit. The key path detection unit is connected in series with the key circuit on the car door panel via a wire, while the key feedback detection unit is connected in parallel with the key circuit via a sensor. The key path detection unit and the key feedback detection unit transmit the path status signal and feedback signal to the data processing module 2 via independent signal lines. The key path detection unit and the key feedback detection unit are arranged adjacent to each other in physical location, and their signal lines are all concentrated at the port of the signal acquisition module 1 for easy connection with the data processing module 2.

[0023] Data processing module 2 receives signals from adapter switching module 3, power detection module 4, and signal acquisition module 1, and processes them sequentially according to a preset order. First, data processing module 2 determines the currently connected door panel model based on the positioning signal and connection status signal sent by adapter switching module 3. Second, data processing module 2 adjusts the operating parameters of load simulation module 9 based on the voltage and current signals sent by power detection module 4. Finally, data processing module 2 analyzes and processes the received path status signal and feedback signal, and transmits the results to display unit 5 and voice prompt module 6. The hardware structure of data processing module 2 includes a central processing unit and multiple input / output interfaces, which are connected to the signal lines of adapter switching module 3, power detection module 4, signal acquisition module 1, and load simulation module 9, respectively.

[0024] The detection power supply module 4 includes a voltage regulation unit and a current monitoring unit. The voltage regulation unit adjusts the output voltage value via a rotary knob. The rotary knob's mechanical structure is connected to a potentiometer; rotating it changes the resistance value, thus regulating the voltage. The current monitoring unit monitors the output current value in real time using a Hall effect sensor. The sensing surface of the Hall effect sensor is positioned directly opposite the conductor to ensure accurate capture of current changes. The voltage regulation unit and the current monitoring unit transmit voltage and current signals to the data processing module 2 via independent signal lines.

[0025] The load simulation module 9 is connected to the detection power supply module 4 via a load interface. Internally, the load simulation module 9 contains adjustable resistors and capacitors to simulate actual load conditions. The load simulation module 9 transmits the simulated load signal to the detection power supply module 4 via a signal line. The detection power supply module 4 adjusts its output voltage and current values ​​based on the received simulated load signal. The adjustable resistors and capacitors in the load simulation module 9 can be adjusted manually using a knob or electronically to adapt to different load requirements.

Both the LCD screen and the indicator light module receive processing result signals transmitted from data processing module 2 via signal lines. The LCD screen is mounted on the front of the system, and the indicator light module is located below the LCD screen; both are fixed to the system housing by a bracket. The indicator light module includes red, green, and yellow LEDs, used to indicate abnormal, normal, and warning states, respectively.

[0027] The voice prompt module 6 includes a speaker and an audio processor. The speaker receives the voice signal transmitted from the data processing module 2 through the audio processor. The input port of the audio processor is connected to the output port of the data processing module 2. The speaker is mounted on the top of the system, with its sound output direction facing forward so that the user can hear the prompt information. The hardware structure of the voice prompt module 6 also includes a volume adjustment knob for adjusting the speaker's output volume according to ambient noise.

[0028] The specific operation process of this utility model is as follows: First, the system is fixedly connected to the car door panel through the mechanical positioning unit 7 of the adapter switching module 3, while the electrical connection unit 8 is connected to the door panel circuit interface. The mechanical positioning unit 7 and the electrical connection unit 8 transmit positioning signals and connection status signals to the data processing module 2, respectively. The data processing module 2 determines the model of the currently connected door panel based on these signals. Next, the detection power supply module 4 supplies power to the car door panel through the power interface, while the load simulation module 9 simulates the load situation in actual use through the load interface and transmits the simulated load signal to the detection power supply module 4. The detection power supply module 4 adjusts the output voltage and current values ​​according to the simulated load signal. The key circuit detection unit and key feedback detection unit of the signal acquisition module 1 detect the circuit status and feedback signal of the key circuit, respectively, and transmit these signals to the data processing module 2. After analyzing and processing the received signals, the data processing module 2 displays the results on the LCD screen and intuitively reflects the detection status through the color change of the indicator light module. At the same time, the detection results and related information are broadcast through the speaker of the voice prompt module 6.

[0029] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.

[0030] In the actual testing process, the electrical testing system is first fixedly connected to the vehicle door panel under test via the mechanical positioning unit 7 of the adapter switching module 3. The threaded structure of the mechanical positioning unit 7 engages with the mounting holes on the door panel through rotation, ensuring a stable connection between the system and the door panel. Simultaneously, the elastic contacts of the electrical connection unit 8 directly contact the circuit interface on the door panel, ensuring reliable transmission of electrical signals. The mechanical positioning unit 7 and the electrical connection unit 8 transmit positioning signals and connection status signals to the data processing module 2, respectively. The data processing module 2 determines the model of the currently connected door panel based on these signals and calls the corresponding testing parameter configuration. This step, through a dual mechanical and electrical connection design, achieves rapid adaptation to different door panel models, solving the problem of insufficient compatibility of existing equipment.

[0031] Next, the detection power module 4 supplies power to the car door panel through the power interface, while the load simulation module 9 simulates the load conditions in actual use through the load interface. The adjustable resistors and capacitors inside the load simulation module 9 are adjusted to suit the current load conditions of the door panel according to preset values, and the simulated load signal is transmitted to the detection power module 4. The detection power module 4 dynamically adjusts the output voltage and current values ​​based on the received simulated load signal to ensure that the power supply environment is consistent with the actual usage scenario. During this process, the voltage regulation unit changes the resistance value of the potentiometer through a rotary regulator, thereby precisely controlling the output voltage; the current monitoring unit uses a Hall effect sensor to capture changes in the output current in real time and transmits the relevant signals to the data processing module 2. Through these steps, the system can accurately simulate the electrical characteristics of the door panel buttons under actual working conditions, thereby improving the reliability of the detection results.

[0032] Subsequently, signal acquisition module 1 begins operation. Its button path detection unit is connected in series with the door panel button circuit via wires to detect the path status of the button circuit. The button feedback detection unit is connected in parallel with the button circuit via a sensor to acquire feedback signals from button operations. The button path detection unit and the button feedback detection unit transmit the path status signal and feedback signal to data processing module 2, respectively. Data processing module 2 analyzes and processes the received signals, including determining whether there are open circuits, short circuits, or abnormal feedback in the button circuit. If an abnormality is detected, data processing module 2 generates a corresponding fault code and transmits it to display unit 5 and voice prompt module 6. This step, through comprehensive testing of the button circuit, avoids functional abnormalities caused by manufacturing or assembly problems, improving testing efficiency and accuracy.

[0033] After signal processing is complete, the LCD screen of display unit 5 displays the test results in a graphical interface, including the status information of the button circuit, power parameters, and specific fault descriptions. The indicator light module uses red, green, and yellow LEDs to visually reflect the test status: green indicates normal, red indicates abnormal, and yellow indicates a warning. Simultaneously, the speaker of voice prompt module 6 broadcasts the test results and related information, such as "Test complete, button function normal" or "An abnormality was detected; please check the button circuit." The voice prompts are generated by the audio processor based on the signal transmitted from data processing module 2, and the user can adjust the speaker's output volume using the volume control knob according to ambient noise. This multimodal information output ensures that the user can quickly obtain the test results and take appropriate action.

[0034] Through the above steps, this invention achieves efficient detection of various door panel electronic control buttons. Its core principle lies in achieving rapid adaptation to different door panels through the mechanical positioning unit 7 and electrical connection unit 8 of the adaptation switching module 3; providing stable power support and a realistic load environment through the detection power supply module 4 and load simulation module 9; comprehensively detecting the status of the button circuit through the signal acquisition module 1; and intuitively presenting the detection results through the display unit 5 and voice prompt module 6. The entire system operates with clear logic and ease of use, significantly improving detection efficiency and reducing detection costs, meeting the needs of modern automobile manufacturing for rapid switching and detection of multiple door panels.
