[0038] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0039] like Figures 1 to 7 As shown, this utility model provides a portable vehicle-mounted cabinet test box, including a test module 19 and a box body 10 with multiple surfaces. The test module 19 is disposed inside the box body 10 and is used for simulating signals. The surface of the box body 10 is provided with a test wiring port 11, a power interface 12, an operation module 13 and a display module 14. The test module 19 is electrically connected to the test wiring port 11, the power interface 12, the operation module 13 and the display module 14. The surface of the box body 10 is provided with at least two test wiring ports 11.
[0040] The test box is small and portable. It tests the functionality of the vehicle cabinet by simulating signals through the test module 19, enabling quick inspection at the loading site and eliminating abnormalities that may occur during transportation and handling. It integrates functions such as analog signal generation, power supply, user interface and result display. It can record and output test data while performing functional tests, and is easy to carry to different work locations. It is equipped with at least two test wiring ports 11, which support simultaneous or sequential testing of multiple lines, greatly improving work efficiency.
[0041] The test module 19 can be a PCB and has analog signal functionality. The surface of the housing 10 is also equipped with a handle 15. The test wiring port 11, power interface 12, operation module 13, and display module 14 are all located on different surfaces of the housing 10 from the handle 15. The handle 15 design makes the test box easier to carry and move, especially when frequent changes in test location are required or field operations are performed. By separating the handle 15 from other functional modules, the risk of accidental contact with the operation module 13 or pulling of cables during handling is reduced, thereby improving safety during use.
[0042] In order to make the cable wiring of multiple lines more reasonable, at least two different surfaces of the box body 10 are provided with test connection ports 11. The test connection ports 11 arranged on multiple surfaces can more effectively utilize the space of the test box, so that more ports can be arranged without increasing the volume of the device, greatly improving the work efficiency. The port layout on different surfaces can optimize the wiring path according to the actual use scene, reduce the entanglement and intersection between cables, thereby simplifying the operation process on site, and can reduce the safety hazards caused by excessive cable aggregation on a single surface, such as tripping risk or accidental removal of cables. Preferably, two surfaces of the box body 10 are provided with test connection ports 11, which can meet the installation of a large number of test connection ports 11, and other surfaces can also be reserved for the installation of other components.
[0043] Further, the test connection ports 11 are located on adjacent surfaces of the box body 10. The design of adjacent surfaces allows technicians to approach the test box from two directions, improving the convenience of accessing cables, especially in space-limited situations. In the present embodiment, the two surfaces provided with test connection ports 11 are adjacent.
[0044] Among them, the surface of the same box body 10 is provided with at least two test connection ports 11, and the at least two test connection ports 11 are arranged at intervals. The interval arrangement of the ports helps to maintain the spacing between the cables, reduce cable entanglement and confusion, especially when frequent connection replacement or rapid debugging is required, making it easier to access and remove cables, which can significantly improve work efficiency.
[0045] Since the power input is usually a high-voltage part and the data transmission is usually a low-voltage part, in order to improve the safety of use, the test connection ports 11 and the power interface 12 are located on different surfaces of the box body 10. By arranging the test connection ports 11 and the power interface 12 on different surfaces of the box body 10, the access positions of the power line and the signal line are separated, the power input and the signal input are separated, which helps to reduce electromagnetic interference, especially when different test cables need to be frequently replaced, so that the power line and the signal line can be accessed from different directions, and the risk of misplug is also reduced.
[0046] Since there are many cables during the test process, in order to ensure the display effect of the display module 14, the display module 14, the test connection ports 11 and the power interface 12 are located on different surfaces of the box body 10. By distributing different types of interfaces on different surfaces, the cable routing can be more reasonably arranged, the cable crossing and entanglement can be reduced, and the situation that the display module 14 is blocked by the cable can also be reduced.
[0047] In order to protect the staff from using the operation module 13, the operation module 13, the test connection port 11 and the power interface 12 are located on different surfaces of the box body 10. By distributing different types of interfaces on different surfaces, the cable layout can be more reasonable, the cable crossing and winding can be reduced, the working area can be kept clean, the operation module 13 can be separated from other interfaces, and the risk of misoperation caused by accidental touch can be reduced.
[0048] In this embodiment, the operation module 13 and the display module 14 are located on the same surface of the box body 10. By placing the operation module 13 and the display module 14 on the same surface, the user can conveniently operate while checking the test results, and the user can more intuitively see the operation results, and the instant feedback helps to quickly confirm whether the settings are correct. In this way, the user does not need to frequently move the line of sight or adjust the body position, and the work efficiency is improved.
[0049] In order to facilitate the use of the test box on site, at least one side surface of the box body 10 is not provided with the test connection port 11, the power interface 12, the operation module 13 and the display module 14. Reserving a surface without interfaces or control elements can enhance the structural strength of the entire box body 10, and this surface can be used as a support surface to facilitate the use of the test box in different positions.

The display module 14 and the operation module 13 are located on the front surface 111, and the back surface of the box body 10 is not provided with the test connection port 11, the power interface 12, the operation module 13 and the display module 14, and is used as a support surface to support the box body 10. The front surface 111 and the back surface of the box body 10 have the largest area, can accommodate a larger number of operation modules 13 and display modules 14, and can provide a larger support surface to ensure the stable placement of the test box. Among them, the left side surface 141 of the box body 10 is provided with two test connection ports 11, and the rear surface 131 of the box body 10 is provided with three test connection ports 11.
[0051] In order to increase the support stability, the back surface of the box body 10 is also provided with a plurality of supporting feet 16, so that the back surface of the box body 10 is suspended, air enters easily, and the heat dissipation performance of the test box is improved.
[0052] Specifically, the operation module 13 is a dial switch, and a plurality of dial switches are arranged.
[0053] During testing, the power supply is connected to the power supply interface 12 of the portable vehicle-mounted cabinet test box, different types of vehicle-mounted cabinet cables are connected to the corresponding test connection ports 11 on the left side 141 and the back 131 of the box body 10 according to the marks, and the vehicle-mounted cabinet is powered on.

[0061] It can be understood that in other embodiments, the display module can be a liquid crystal display screen, which can directly display the test results, and the liquid crystal display screen can also support touch control, and the operation module is completed through touch control.
