DETAILED DESCRIPTION

[0018] As Figures 1-2 Shown, a kind of hybrid power light truck overall arrangement structure based on power split, including engine 2, input type power split hybrid assembly 3, power battery 4, all -in -one integrated controller 5, battery integrated heat management unit 6, hybrid oil cooling device 7, motor electric control water cooling radiator 8, charging socket 9, low -voltage battery 10, urea tank 11, post -treatment device 12 and oil tank 13:

[0019] Engine 2 and input type power split hybrid assembly 3 are arranged in the rear portion below cab 1 and inboard of frame;

[0020] The power battery 4, multi-in-one integrated controller 5, battery integrated thermal management unit 6, hybrid oil cooling device 7, motor and electronic control water cooling radiator 8, and charging socket 9 are arranged on the left side of the vehicle frame. The power battery 4 is arranged on the left side of the vehicle frame. In pure electric mode, it provides power to the input power split hybrid powertrain 3 or provides assistance in climbing conditions to ensure normal vehicle operation. The hybrid oil cooling device 7 is the existing hybrid oil cooling system of hybrid light trucks, and the charging socket 9 is the power battery charging interface. The motor and electronic control water cooling radiator 8 serves as the cooling system for the input power split hybrid powertrain 3 and the multi-in-one integrated controller 5 to ensure normal vehicle operation.

[0021] The low-voltage battery 10, urea tank 11, after-treatment system 12, and fuel tank 13 are located on the right side of the vehicle frame. The low-voltage battery 10 serves as the low-voltage power supply system for the entire vehicle; the fuel tank 13 provides power to the engine 2 in both engine mode and hybrid mode.

[0022] like Figure 1 As shown, engine 2 and input-type power split hybrid powertrain 3 serve as the vehicle's power source, mounted on the left longitudinal beam 15 and right longitudinal beam 14 of the frame. The input-type power split hybrid powertrain 3 includes motor M1, motor M2, and gearbox; motor M1, motor M2, and gearbox are integrated into a single unit. The layout is compact and highly integrated.
