[0037] The method of using this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 6As shown, an integrated power management box for an unmanned vehicle chassis includes:

[0042] An emergency stop switch 23 is located on the inner wall of the rear of the housing 1.

[0043] Also includes:

[0044] The power output line 3 is located on the inner wall of the housing 1 and is electrically connected to the power switch 22.

[0045] Air switch 4, located at the bottom of the enclosure 1, is electrically connected to the power output line 3; emergency stop switch 23 connects to the power box communication connector 83 to control the working status of the power management box. Air switch 4 automatically disconnects when the current is too high and automatically reconnects when the current is restored.

[0046] Junction box 5 is located on the inner walls of both sides inside the housing 1 and is electrically connected to the air switch 4. The function of junction box 5 is to distribute the power supply and control signals of the vehicle's electrical equipment and to provide overload or short circuit protection for each electrical device and wiring harness.

[0047] The relay fuse box 6 is located on the inner wall of the rear of the box 1 and is electrically connected to the air switch 4.

[0048] A voltmeter 7 is located on the inner wall of the rear of the housing 1 and is electrically connected to the air switch 4. The voltmeter 7 is a 12V voltmeter used to display the voltage of the small battery.

[0049] The connection module 8 is located on the side of the cover plate 2 and is electrically connected to the junction box 5.

[0050] When the power management box encounters a fault, the air switch 4 will cut off the power to the faulty module. Therefore, during inspection, it is possible to directly identify which module is faulty and then repair it accordingly. After troubleshooting the power supply load fault or line short circuit fault, simply press the button switch of the relay fuse box to restore normal power supply.

[0051] Because the power management box uses a CAN communication module to communicate with the computer control center, and the various lines are modularly distributed, it is easy to install and has been disassembled and replaced; it features fast communication speed, high efficiency, easy maintenance, and good real-time performance.

[0052] The cover plate 2 has two first rectangular through holes 21 on its side, four second rectangular through holes 211 on its surface, and four circular through holes 212 on its surface. The second rectangular through holes 211 and the circular through holes 212 are on the same horizontal line, and some of the circular through holes 212 are located between the second rectangular through holes 211. The first rectangular through holes 21 are located above the second rectangular through holes 211.

[0053] The connection module 8 includes:

[0054] Six first female connectors 81 are provided. One first female connector 81 is provided on one first rectangular through hole 21, three first female connectors 81 are respectively provided on three second rectangular through holes 211, and the remaining two first female connectors 81 are provided on the inner wall of the rear end of the housing 1. The six first female connectors 81 are electrically connected to the junction box 5. The six 48V female connectors are connected to the motor controller power supply, the DC-DC input power supply and the power supply for the holding brake.

[0055] Three terminals 82 are located on part of the circular through hole 212 and are electrically connected to the junction box 5; the three terminals 82 are respectively powered by EPS, VCU and BCM.

[0056] The power supply box communication connector 83 is located on the remaining circular through holes 212 and is electrically connected to the junction box 5; the power supply box communication connector 83 is connected to the emergency stop switch 23 to send emergency stop signals and to control the brake relay.

[0057] When wiring problems occur, connecting to the central computer allows for detailed information about the wiring issues to be sent to the computer for troubleshooting. Maintenance personnel can periodically check the voltage and current data in the power management box using the data displayed on the computer. This data helps determine if maintenance of the vehicle's electrical systems is necessary, effectively reducing the wear and tear on the battery caused by internal electrical faults in the autonomous vehicle chassis, and extending the battery's lifespan and driving range.

[0058] Two second female connectors 84 are provided. One second female connector 84 is provided on another first rectangular through hole 21, and the other second female connector 84 is provided on the remaining second rectangular through hole 211. The two second female connectors 84 are electrically connected to the junction box 5. Two 12V output female connectors are used for power input and power output.

[0059] The rear end of the box 1 is provided with a sealing strip 9. The sealing strip 9 is used to seal the box 1.

[0060] The power supply box communication connector 83 is electrically connected to the emergency stop switch 23. The power supply can be cut off via the emergency stop switch 23.

[0061] The first female connector 81 is a 48V female connector, and the second female connector 84 is a 12V female connector. The 12V output female connector is used for lead-acid battery input and output, and the battery output line assembly is connected to the lithium battery output current.

[0062] Working process: When the unmanned vehicle starts running, it supplies power to the power management box through the lithium battery, and then connects to the junction box 5 through the power output line 3. The junction box 5 is connected to three 12V terminals 82, the power box communication connector 83, six 48V female connectors, and two 12V output female connectors, so that the three terminals 82 respectively supply power to EPS, VCU and BCM. The power box communication connector 83 is connected to the emergency stop switch 23 to send emergency stop signals and control the brake relay. The six 48V female connectors are connected to the motor controller power supply, DC-DC input power supply and brake power supply. The two 12V output female connectors are for power input and power output.

[0063] Since all modules are ultimately connected to air switch 4, when the power management box encounters a fault, air switch 4 will cut off the power to the faulty module. Therefore, during inspection, it is possible to directly identify which module is faulty and then repair it accordingly. After troubleshooting power supply load faults or line short circuit faults, simply press the button switch in the relay fuse box to restore normal power supply.
