[0031] The electric control system 15 is divided into high -voltage system and low -voltage system two parts, the high -voltage system provides the power of the vehicle, and the low -voltage system controls the whole vehicle information display and light, heater and other functions;

[0032] The material box assembly 16 is a vehicle loading bin, and two groups of lifting oil cylinders are arranged at the bottom, and the hydraulic system 13 is responsible for oil supply, when the vehicle reaches the unloading site, the hydraulic system 13 supplies oil to the lifting oil cylinder according to the instruction, the oil pressure in the oil cylinder rises, the piston rod is pushed out, and then the material box assembly 16 is lifted, the material box is inclined at a certain angle, the self -discharging of the goods loaded by the vehicle is realized, and the rapid unloading of the underground material is facilitated;

[0035] Working principle:

[0036] First step, the two mining explosion-proof lithium-ion batteries in the power source automatic force system 14 are connected in series to the junction box, and high and low voltage electricity is delivered to the electric control system 15 through the junction box and the power supply control box, wherein the high voltage system drives the vehicle forward by using the electric energy provided by the battery, and gives power to the vehicle operation; the low voltage system is responsible for controlling the whole vehicle information display, such as speed, power and other state information directly presented to the driver, and controls the light for underground lighting and the heating function, ensuring the comfort of the driving environment, especially maintaining the appropriate temperature in the cold underground environment, the drive axle assembly 12 is directly connected with the drive motor, receives the power instruction from the electric control system 15, efficiently converts the electric energy into mechanical energy, drives the wheels to rotate, and promotes the vehicle to move forward, and no tail gas is generated during the operation, the emission of toxic and harmful gases to the mine environment is zero, which helps to improve the underground working environment, the use of electric energy can reduce energy consumption, and the maintenance cost is relatively low due to the absence of complex mechanical parts such as engine, mainly the maintenance of battery pack and electrical system.

[0037] The hydraulic system 13 as a key execution part is arranged on one side of the rear frame assembly 18, and contains hydraulic oil tank, valve group, oil pump motor, explosion-proof electromagnet and other components inside, when the vehicle needs to turn, the hydraulic system 13 supplies oil to a group of oil cylinders at the hinge position of the front and rear frames, with the change of oil pressure in the oil cylinder, the front and rear frames are pushed to rotate relatively, the rear frame assembly 18 and the front frame assembly 11 realize flexible steering by the hinge structure, so as to achieve the maximum turning angle and the minimum turning radius of the vehicle, and ensure that the vehicle can accurately turn in the narrow space underground.

[0038] Second step, the driving and parking system 17 is installed on both sides of the front and rear axles, adopts wet brake, and is closely related to the hydraulic system 13, and the brake form has four-wheel braking characteristics, which means that the four wheels can be braked synchronously to ensure that the vehicle is stable and stopped, and the braking process relies on spring braking and hydraulic release mechanism, in the normal driving state, the hydraulic system 13 provides pressure to offset the braking force of the spring, and the vehicle runs smoothly; once an emergency occurs, such as sudden obstacles or emergency stop, the pressure of the hydraulic system 13 decreases or disappears, and the spring force quickly acts to push the brake to clamp the brake disc to realize emergency braking, and when parking, the brake state is maintained by relying on the spring force, so that the vehicle can be reliably parked on the slope or stationary, even if the hydraulic system 13 fails, the failure safety design can also ensure that the vehicle maintains braking to avoid the situation of vehicle sliding.

[0039] The material box assembly 16 serves as the loading bin for the vehicle. It is equipped with two sets of lifting cylinders at the bottom, which are supplied with oil by the hydraulic system 13. When the vehicle arrives at the unloading location, the hydraulic system 13 supplies oil to the lifting cylinders according to the instructions. The oil pressure in the cylinders increases, pushing the piston rod to extend and lift the material box assembly 16, causing the material box to tilt at a certain angle, thereby realizing the self-unloading of the goods loaded on the vehicle and facilitating the rapid unloading of materials underground.
