Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] See attached document Figure 1-2 A range-extended mining truck chassis power system layout structure mainly includes: a radiator assembly 1, an air filter assembly 2, a third crossbeam assembly 3, a muffler assembly 4, a power battery assembly 5, a drive motor and gearbox assembly 6, a fuel tank assembly 7, a fuel filter assembly 8, a range extender assembly 9, and a frame 10, etc.; the radiator assembly 1, the range extender assembly 9, the third crossbeam assembly 3, and the drive motor and gearbox assembly 6 are disposed within the frame 10, the air filter assembly 2, the muffler assembly 4, and the power battery assembly are disposed on one side of the frame 10, and the fuel tank assembly 7 and the fuel filter assembly 8 are disposed on the other side of the frame 10. The radiator assembly 1 is located directly in front of the range extender assembly 9 and is connected to the engine assembly of the range extender assembly via pipes to cool the engine assembly; the air filter assembly 2 is connected to the turbocharger intake of the engine assembly and is located on the same side of the mine car; the muffler assembly 4 is connected to the turbocharger exhaust of the engine assembly and is located on the same side of the mine car; the empty fuel tank assembly 7 is connected to the engine oil outlet of the engine assembly and is connected to the engine oil inlet of the engine assembly via the fuel filter assembly 8 and is located on the same side of the mine car.

[0025] The generator assembly of the range extender assembly is connected to the drive motor, gearbox assembly, and power battery assembly.

[0026] The range extender assembly consists of an engine assembly, a generator assembly, and a control system. The engine in the engine assembly can be an internal combustion engine, such as a gasoline or diesel engine, or other types of power units, such as fuel cells. The generator in the generator assembly converts the mechanical energy output from the engine into electrical energy to charge the batteries of electric devices or directly power the electric motor. The control system is responsible for monitoring and controlling the operating status of the range extender to ensure its safe and efficient operation.

[0027] The radiator assembly 1 is located directly in front of the range extender assembly 9, and is connected via piping to the turbocharger outlet, engine intake, engine coolant outlet, and engine coolant inlet of the engine assembly to cool the engine. The air filter assembly 2 is located on the front right side of the frame, connected to and on the same side as the turbocharger intake of the engine assembly, facilitating piping connections. The third crossbeam assembly 3 is installed between the range extender assembly 9 and the drive motor and gearbox assembly 6 to reinforce the frame, reduce the impact of the range extender assembly and drive motor and gearbox assembly on the frame, and improve the frame's service life. The muffler assembly 4 is located in the middle right side of the frame, on the same side as the turbocharger exhaust port of the engine assembly, facilitating piping connections. The power battery assembly 5 is located on the right side of the frame and behind the muffler assembly 4; the drive motor and gearbox assembly 6 is located behind the third crossbeam assembly 3 and in the middle of the frame; the generator assembly is connected to the power battery assembly and the drive motor and gearbox assembly respectively; the empty fuel tank assembly 7 is located on the left rear of the frame, on the same side as the engine oil outlet of the engine assembly, which facilitates pipeline connection; the fuel filter assembly 8 is located in front of the fuel tank and behind the range extender assembly 9. The fuel filter assembly 8 is connected to the fuel tank assembly 7 and the engine oil inlet; the range extender assembly 9 is located in the middle of the front of the frame and behind the radiator assembly 1; the frame 10 provides mounting support for the various components of the power system.

[0028] Preferably, an electric fan is integrated into the radiator assembly. The electric fan is secured by four bolt holes around the circular opening in the radiator shroud and is positioned next to the engine crankshaft structure. The electric fan is powered by the vehicle battery, and its rotation is controlled by the vehicle controller. The engine crankshaft fan is a mechanical fan, connected to the engine crankshaft via a pulley. When the engine is running, the crankshaft rotation drives the fan to rotate for cooling. In this design, the total power of the electric fans is 4kW, while the mechanical power of the engine crankshaft fan is significantly greater than the power of the electric fans when operating.

[0029] Example 2:

[0030] An extended-range mining truck is equipped with the extended-range mining truck chassis power system layout structure described in Embodiment 1, wherein the radiator assembly 1, air filter assembly 2, third crossbeam assembly 3, muffler assembly 4, power battery assembly 5, drive motor gearbox assembly 6, fuel tank assembly 7, fuel filter assembly 8, and range extender assembly 9 are mounted on the frame 10 via connectors and mounting brackets.

[0031] The radiator assembly in this invention uses an electric fan to cool the engine, which is simpler to install than the commonly used crankshaft fan cooling system. The electric fan also consumes less energy than the crankshaft fan. Furthermore, the air filter assembly, muffler assembly, fuel tank assembly, and fuel filter assembly are arranged on the left and right sides of the frame according to the engine interface locations, sharing the same side as the corresponding engine interfaces. This results in a simpler and more rational piping layout. The range extender assembly and drive motor / gearbox assembly are respectively located in front of and behind the third crossbeam of the third crossbeam assembly. During vehicle operation, this significantly reduces the forces exerted by the range extender assembly and drive motor / gearbox assembly on the frame, extending the frame's lifespan.

[0032] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
