Existing explosion-proof high-voltage distribution boxes and battery management systems (BMS) are typically designed separately, housed in different enclosures. This design leads to a more complex overall layout of the mining vehicle and increases the risk of signal interference between systems, especially in wiring arrangements, where signal cross-interference is prone to occur.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] Reference Figure 1 and Figure 2 As shown, this utility model provides a high-voltage power distribution equipment, including: a housing 1, a BMS control device 2, a wiring assembly 3, and a power distribution device 4; the housing 1 is provided with a first cavity 12 and a second cavity 13; the BMS control device 2 is located in the first cavity 12 and includes a relay 22 and a BMS main board 21 electrically connected; the wiring assembly 3 includes a terminal block 31 located between the first cavity 12 and the second cavity 13, and the power supply is electrically connected to the relay 22 via the terminal block 31, the relay 22 providing low-voltage power to the BMS main board 21; the power distribution device 4 is located in the second cavity 13, and the relay 22 is electrically connected to the power distribution device 4 to be suitable for supplying power to external power distribution equipment.
[0030] Specifically, the enclosure 1 is divided into a first cavity 12 and a second cavity 13. The BMS control device 2 is located in the first cavity 12, and the power distribution device 4 is located in the second cavity 13. By integrating the power distribution device 4 and the BMS control device 2 into the same enclosure 1, the overall layout footprint of the equipment is reduced, and the internal wiring structure is optimized, thereby avoiding the complexity caused by cable crossings in a distributed layout. Circuit connections are achieved through terminal blocks 31, simplifying wiring and reducing the risk of electromagnetic interference and signal interference, thus improving system stability. The compartmentalized structure and flame-retardant design isolate high-voltage and low-voltage components, enhancing the explosion-proof safety of the system to suit complex environments such as mines, thereby improving the safety and reliability of the equipment.
[0031] Reference Figure 5 As shown, in the first aspect embodiment of the present invention, a partition 11 is provided in the middle of the housing 1. The partition 11 is adapted to divide the housing 1 into a first cavity 12 and a second cavity 13, and the wiring terminal 31 is passed through the partition 11.
[0032] Specifically, the partition 11 is located in the middle of the enclosure 1 to divide the enclosure 1 into a first cavity 12 and a second cavity 13. The first cavity 12 is used to install the BMS control device 2, and the second cavity 13 is used to install the power distribution device 4, thereby achieving a high degree of integration between the BMS control device 2 and the high-voltage power distribution device 4. Through the connection of the wiring terminal 31, the wiring is simplified, electromagnetic interference is reduced, and cross interference of the distribution wiring is reduced, thus reducing the complexity of the layout and facilitating the later equipment maintenance.
[0033] In a first aspect of this utility model, the high-voltage power distribution equipment further includes a through-wall terminal 5 disposed on the partition 11, the through-wall terminal 5 providing signal transmission for the BMS main board 21.
[0034] Specifically, the through-wall terminal 5 is installed on the partition 11 of the enclosure 1 to achieve explosion-proof signal transmission. When the ignition switch is opened, the vehicle control system sends a wake-up signal to the BMS main board 21. This wake-up signal is transmitted to the BMS main board 21 through the through-wall terminal 5. After receiving the wake-up signal, the BMS main board 21 controls the relay 22 to output high-voltage power to the power distribution device 4. The design of the through-wall terminal 5 ensures both the stability of signal transmission and the safety of the equipment in high-voltage operating environments, making it suitable for complex operating environments such as mines.
[0035] Reference Figure 5 As shown, in the first aspect embodiment of the present invention, the wiring assembly 3 further includes a plurality of terminals 32, which are disposed on the partition 11 to be adapted to connect the terminal block 31 and the BMS control device 2, and to connect the relay 22 and the power distribution device 4.

[0037] Reference Figure 4 As shown, in the first aspect embodiment of this utility model, the high-voltage power distribution equipment further includes a cable entry device 7 and a cable exit device 8. The cable entry device 7 and the cable exit device 8 are respectively disposed on the two side walls of the housing 1. The high-voltage power supply and the low-voltage power supply enter the second cavity 13 through the cable entry device 7. The power distribution equipment is connected to the external power distribution equipment through the power distribution cable, and the power distribution cable passes through the cable exit device 8.
[0038] Reference Figure 4 As shown, according to a first aspect of the present invention, the power distribution device 4 includes a copper busbar 41 and an output fuse 42 connected to the copper busbar 41. The copper busbar 41 is connected to a relay 22 via a terminal block 32, so that high-voltage power is output to the output fuse 42 via the relay 22.
[0039] Specifically, to achieve efficient and safe power distribution, the high-voltage power distribution equipment also includes a cable entry device 7 and a cable exit device 8. Cables are routed through the cable entry device 7 and the cable exit device 8 to rationally plan the cable routing, avoid cross-location, and prevent interference with subsequent maintenance. In some embodiments of this utility model, the cable entry device 7 and the cable exit device 8 are respectively located on two opposite side walls of the enclosure 1 to ensure rational cable routing.
[0040] Understandably, the power distribution unit 4 includes a copper busbar 41 and an output fuse 42. The copper busbar 41 transmits high-voltage power to the relay 22 through the terminal block 32, while the output fuse 42 protects the circuit system from overload or short circuit. When the relay 22 receives a control signal from the BMS main board 21, the copper busbar 41 outputs high-voltage power to the external power distribution equipment, ensuring the safe and reliable operation of the system.
[0041] Reference Figure 3 As shown, in the first aspect embodiment of this utility model, the high-voltage power distribution equipment further includes a current sensor 6 disposed in the first cavity 12. The current sensor 6 is connected to the input terminal of the BMS main board 21 and is adapted to monitor the current.
[0042] Specifically, to further enhance system stability, a current sensor 6 is also installed within the first cavity 12. This current sensor 6 is connected to the input terminal of the BMS mainboard 21 to monitor the current data passing through the BMS control system in real time. When the BMS mainboard 21 detects an abnormal current, it controls the disconnection of the high-voltage power supply to prevent system malfunctions or electrical accidents. This improves system safety and real-time monitoring capabilities. The current sensor 6 is a Hall effect sensor.
[0043] In a first aspect of this utility model, the relay 22 includes a positive relay and a negative relay, which are used to control the positive and negative outputs of the high-voltage power supply, respectively.
[0044] In a first aspect of this utility model, a plurality of fixed connectors are provided on the side wall of the housing 1 to enhance the system’s impact resistance and explosion-proof capability.
[0045] Secondly, this utility model also provides a mining vehicle, including a chassis and high-voltage power distribution equipment, with the high-voltage power distribution equipment mounted on the chassis.
[0046] Specifically, installing this high-voltage power distribution equipment on mining vehicles can adapt to complex environments such as mines, enhance the explosion-proof safety of the system, and improve the safety and reliability of the vehicles.
