For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-4 As shown, a modular frame layout structure of a new energy light truck includes a frame, a power battery 5, an integrated electric drive axle 8, a brake line 10, a high-voltage cable 11 and a low-voltage wiring harness 14;

[0022] like Figure 1-3 As shown, the frame adopts a high-strength steel variable-section longitudinal beam straight-through structure; preferably, a 135-180×4.5mm variable-section longitudinal beam straight-through frame platform is adopted, which can reduce the overall height of the cab and meet the vehicle layout of various technical routes of new energy light trucks. The frame hole positions are standardized in size and distribution, providing support for the standardized design of the mounting bracket of the electrified components connected to the frame. The middle crossbeam is closely connected to the upper wing surface of the longitudinal beam, optimizing the layout space of the power battery 5, and can accommodate a 100kWh single PACK (combination battery) power battery 5 mid-placement solution, thereby increasing the ground clearance of the power battery, and the no-load ground clearance is greater than 400mm, thereby improving the vehicle's passability;

[0023] like Figure 1 As shown, the power battery 5 is arranged in the middle of the frame; preferably, the power battery 5 includes a frame and a battery pack; the frame is fixed to the outer side of the belly of the left and right longitudinal beams of the frame by connecting plates and bolts, and the battery pack is arranged in the middle of the left and right longitudinal beams of the frame. The overall ground clearance is increased, so that the battery collision safety and the risk of bottom damage in bad road conditions are effectively reduced;

[0024] like Figure 2 As shown, the integrated electric drive axle 8 is arranged at the rear of the vehicle frame; the integrated electric drive axle 8 is integrated with the rear axle, and the integrated electric drive axle 8 cancels the mid-mounted gearbox, and the overall occupied volume is greatly reduced to carry battery solutions of different capacities, and can optimize the power chain transmission efficiency, improve the energy consumption and reliability of the whole vehicle, and improve the efficiency of the whole vehicle;

[0025] like Figure 2-3As shown, the high-voltage cable 11 and the brake line 10 are arranged on the inner side of the left longitudinal beam of the frame in an upper and lower offset manner, and the low-voltage wiring harness 14 is arranged on the inner side of the right longitudinal beam of the frame; not only can the risk of insulation failure caused by water accumulation in the wiring harness be effectively avoided, but the separate arrangement can also effectively utilize the space inside the frame and avoid mutual interference due to concentrated distribution.

[0026] like Figure 1 , 4 As shown, it also includes an air-conditioning compressor 1, a cooling system unit 2, an integrated controller 4 and a battery 3; the air-conditioning compressor 1, the cooling system unit 2 (a cooling system commonly used in new energy light trucks), the integrated controller 4 and the battery 3 are arranged at the front of the frame and below the cab; the modular centralized arrangement saves layout space.

[0027] like Figure 4 As shown, the front part of the vehicle frame is provided with an integrated controller 4; the integrated controller 4 and the battery 3 are provided on the front part of the vehicle frame through the integrated controller 4 bracket. The integrated controller 4 and the battery 3 are assembled into various parts through the integrated controller bracket 15, and then assembled on the vehicle frame assembly, which optimizes the production process, improves the production efficiency, effectively utilizes the space under the cab, and is also conducive to fault repair and parts maintenance.

[0028] like Figure 1 As shown, it also includes an air cylinder 6 and an electric air compressor 7; the air cylinder 6 and the electric air compressor 7 are arranged on the outer side of the left longitudinal beam in the middle of the frame; the right longitudinal beam space in the middle of the frame is not occupied by other components, which can meet the user's customized modification needs.

[0029] like Figure 2 As shown, it also includes an integrated ABS solenoid valve 13, an integrated dual ABS solenoid valve 9 and a charging socket 12; the integrated ABS solenoid valve 13 is arranged at the front of the frame, the charging socket 12 is arranged on the right longitudinal beam at the front of the frame, and the integrated dual ABS solenoid valve 9 is arranged at the rear of the frame; the overall number of parts is reduced, the weight is light, the assembly convenience is improved, and the energy consumption can be reduced by 3-5%.
