[0032] The following further describes the present application in conjunction with the Figure 1 - Figure 2 drawings.
[0033] An embodiment of the present application discloses a portable integrated power supply device for testing the human body protection of vehicle electromagnetic fields. Referring to Figure 1 and Figure 2 , the power supply device includes a portable box 1 with an open upper surface. A cover 2 is connected to the opening of the portable box 1 for closing and protecting the internal equipment of the box. One end of the cover 2 is hinged to the opening, and a buckle is installed at the other end. The cover 2 is locked with the portable box 1 through the buckle. Inside the portable box 1, a data acquisition module 3 and a GNSS receiver 4 are installed for data acquisition and positioning.
[0034] For the stability of power supply, a three-phase power supply interface 11 is fixedly installed on an outer side wall of the portable box 1. Both the data acquisition module 3 and the GNSS receiver 4 are connected to the three-phase power supply interface 11 through cables, so as to obtain a continuous and stable power supply. In addition, a battery clamp 5 is fixedly connected to another outer side wall of the portable box 1. A power supply battery 51 is installed on the battery clamp 5, and a plug 52 for connecting to the three-phase power supply interface 11 is connected to the power supply battery 51. In this way, the data acquisition module 3 and the GNSS receiver 4 can be powered by the power supply battery 51.
[0035] The battery clamp 5 is fixedly connected to the portable box 1 through bolts, which not only facilitates the installation and disassembly of the battery clamp 5, but also facilitates the maintenance of the battery clamp 5 and the power supply battery 51 installed on the battery clamp 5, improving the maintainability of the equipment.
[0036] Three BNC interfaces 12 and one LAN interface 13 are installed on an outer side wall of the portable box 1. Each BNC interface 12 is connected to the data acquisition module 3 through a cable, and the LAN interface 13 is connected to the GNSS receiver 4 through a cable, facilitating connection with an external data processing computer to achieve rapid data transmission and analysis.
[0037] Referring to Figure 1 and Figure 2, there are two storage cavities, upper and lower, inside the portable box body 1. The lower storage cavity is specifically used to place the data acquisition module 3, and the upper storage cavity is used to place the GNSS receiver 4. To protect the data acquisition module 3 and the GNSS receiver 4, each storage cavity is filled with protective blocks 6, which closely wrap the data acquisition module 3 or the GNSS receiver 4, thus reducing the possible bumps during the movement of the equipment and ensuring the performance and lifespan of the equipment.
[0038] There is also an electromagnetic field probe 7 inside the portable box body 1. This probe is electrically connected to the data acquisition module 3 and is mainly used to detect and feedback electromagnetic field signals. The electromagnetic field probe 7 is placed in the same storage cavity as the GNSS receiver 4 and is also closely wrapped by the protective block 6 to avoid being damaged during transportation and storage.
[0039] The material of the protective block 6 is preferably a soft foam block. Due to its softness, excellent buffering performance, and high cost performance, the soft foam block can effectively protect the data acquisition module 3 and the GNSS receiver 4 from impacts.
[0040] The portable box body 1 includes a rigid plastic outer shell 14 and a metal frame 15. Such a structure not only ensures the lightness of the box body but also guarantees its structural strength. In addition, to enhance portability, multiple self-locking universal wheels 8 are installed on the bottom wall of the portable box body 1, and a retractable pull rod 9 is also installed on one outer side of the portable box body 1, facilitating the user to drag and carry it.
[0041] Multiple ventilation holes 16 are also opened on the bottom wall of the portable box body 1. These ventilation holes 16 are connected to the storage cavity where the data acquisition module 3 is located, and each ventilation hole 16 penetrates through the protective block 6 that wraps the data acquisition module 3, ensuring that the data acquisition module 3 can effectively ventilate and dissipate heat during long-term operation, improving its working stability and lifespan.
[0042] The implementation principle of a portable vehicle electromagnetic field human protection test integrated power supply device in an embodiment of this application is as follows: When testing is required, the plug 52 connected to the power supply battery 51 is connected to the three-phase power interface 11. At this time, the power supply battery 51 supplies power to the data acquisition module 3 and the GNSS receiver 4. When testing is not required, the plug 52 is pulled out of the three-phase power interface 11, and at this time, the power supply to the data acquisition module 3 and the GNSS receiver 4 is cut off.
[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
