Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, this utility model embodiment provides a fault scanning and battery detection diagnostic device, including a detection component 1. The detection component 1 includes a housing 11, a display screen 12, a control panel 13, a main control board 14, a main control module 15, a fault scanning module 16, a battery detection module 17, a display module 18, an input module 19, a communication module 20, a diagnostic cable 21, a connector 22, a first wire 23, a second wire 24, a positive terminal clip 25, and a negative terminal clip 26.

[0027] A display screen 12 is located on the rear of the upper surface of the housing 11, and a control panel 13 is located on the front of the upper surface of the housing 11. A main control board 14 is installed on the rear of the inner side wall of the housing 11. A main control module 15, a fault scanning module 16, a battery detection module 17, a display module 18, an input module 19, and a communication module 20 are located on the lower surface of the main control board 14. The output terminal of the control panel 13 is electrically connected to the input terminal of the input module 19, and the input terminal of the display screen 12 is electrically connected to the output terminal of the display module 18. The input terminal of the fault scanning module 16 is connected via a diagnostic cable. The battery detection module 17 is electrically connected to connector 22 via first wire 23 and second wire 24, and is electrically connected to positive clamp 25 and negative clamp 26 respectively. The main control module 15 is communicatively connected to fault scanning module 16, battery detection module 17, display module 18, input module 19, and communication module 20. As the core control unit, the main control module 15 coordinates the collaborative work of these modules through its communication connections. For example, based on user input via control panel 13, the main control module 15 can dynamically switch between fault scanning and battery detection functions and integrate detection data from different modules. During operation, when the user navigates to menus, inputs parameters, and selects functions via control buttons 30, the main control module 15 processes the input signals in real time and controls display module 18 to update the content of display screen 12.

[0028] In one embodiment, specifically: a lithium battery 27 is fixedly connected to the front of the inner sidewall of the housing 11, and a power module 28 is provided on the rear of the lower surface of the lithium battery 27; wherein, the lithium battery 27 fixedly connected to the front of the inner sidewall of the housing 11 is powered by the power module 28: when the device is connected to an external power source (such as a vehicle battery or a USB interface 29 connected to a power source), the power module 28 prioritizes using the external power source to power the device and to charge the lithium battery 27; when the external power source is disconnected, the power module 28 automatically switches to the lithium battery 27 for power supply.

[0029] In one embodiment, specifically: a USB interface 29 is provided at the center of the front surface of the housing 11. The USB interface 29 is electrically connected to the communication module 20 and the power module 28 respectively. The USB interface 29 is electrically connected to the communication module 20, which supports connecting the device to a computer via a USB cable to realize the uploading, printing and software update functions of the detection data, thus meeting the data management and function upgrade requirements. The USB interface 29 is also electrically connected to the power module 28, which can be connected to an external power source (such as a charger or a computer USB port) to charge the lithium battery 27 on the front inner wall of the housing 11 through the power module 28, or directly power the device when an external power source is connected, thus realizing flexible power switching and battery life support.

[0030] In one embodiment, specifically: the upper surface of the control panel 13 is provided with a plurality of control buttons 30; wherein, the plurality of control buttons 30 include an up button, a down button, an input button and an exit button, used to perform operations such as menu navigation, function selection and parameter input.

[0031] In one embodiment, specifically: a connection indicator light 31 is provided on the front surface of the housing 11 near the USB interface 29. The connection indicator light 31 can display the power connection status or data transmission status (such as charging, connection successful, etc.) in real time.

[0032] In one embodiment, specifically: one end of the diagnostic cable 21 passes through one side of the rear surface of the housing 11, and one end of the first wire 23 and the second wire 24 both pass through the other side of the rear surface of the housing 11. By having one end of the diagnostic cable 21 pass through one side of the rear surface of the housing 11 and one end of the first wire 23 and the second wire 24 pass through the other side of the rear surface of the housing 11, the cables are prevented from getting tangled during operation.

[0033] In one embodiment, specifically: a cover plate 32 is fixedly connected to the bottom of the inner side wall of the housing 11, and the cover plate 32 facilitates the protection of internal components such as the main control board 14.

[0034] In one embodiment, specifically: rubber anti-slip pads 33 are fixedly connected to the front of both sides of the housing 11. The rubber anti-slip pads 33 on the front of both sides of the housing 11 enhance the friction when holding the device, thereby making it easier for the operator to hold the device stably for testing.

[0035] When this invention is in operation: during fault scanning, the operator inserts the connector 22 at one end of the diagnostic cable 21 into the vehicle's data link connector (such as OBD-I). The connector 22 is electrically connected to the fault scanning module 16 on the main control board 14 on the rear inner wall of the housing 11 via the diagnostic cable 21. Subsequently, the user operates the control button 30 through the control panel 13 on the front of the upper surface of the housing 11. The output signal of the control panel 13 is transmitted to the main control module 15 via the input module 19. The main control module 15 activates the fault scanning module 16 to establish communication with the vehicle ECU via the diagnostic cable 21, and reads vehicle fault codes (DTCs), real-time data (such as sensor signals), freeze frame information, etc. After the fault scanning module 16 transmits the acquired data to the main control module 15 for analysis and processing, it is visualized on the display screen 12 on the rear of the upper surface of the housing 11 via the display module 18, such as displaying specific fault codes, real-time data curves, etc. If further analysis or data storage is required, the computer can be connected through the USB interface 29 at the center of the front surface of the housing 11, and the detection data can be uploaded, printed, or the device software updated via the communication module 20.

[0036] During battery testing, the operator clamps the positive terminal clip 25 at the end of the first wire 23 and the negative terminal clip 26 at the end of the second wire 24 onto the positive and negative terminals of the vehicle battery or independent battery, respectively. The positive terminal clip 25 and the negative terminal clip 26 are electrically connected to the battery testing module 17 on the main control board 14 through the first wire 23 and the second wire 24. The user selects the "Battery Testing" function through the control panel 13 and inputs parameters such as battery type (e.g., ordinary lead-acid, AGM battery), standard (e.g., CCA, DIN), and rated capacity (AH value) through the control button 30, and inputs them into module 17. 9. The parameters are transmitted to the main control module 15. The main control module 15 activates the battery detection module 17 to measure the battery's cold start current (CCA), state of health (SOH), voltage, internal resistance, and other parameters based on conductivity testing technology. After the detection data is transmitted from the battery detection module 17 to the main control module 15 for processing, the results are output on the display screen 12 through the display module 18, such as "SOH 75%, battery replacement recommended". If the positive terminal clip 25 and the negative terminal clip 26 are detected to be reversed, the reverse polarity protection circuit built into the battery detection module 17 will automatically cut off the power supply to avoid damage to the device or the battery.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
