[0001] This utility model relates to the field of commercial vehicle technology, specifically to a modular frame layout structure for a new energy small truck and a commercial vehicle. Background Technology

[0002] With the vigorous promotion of new energy commercial vehicles, new energy mini-trucks have become the main force in the urban distribution transportation market, driving the rapid development of the urban last-mile delivery market. Traditional fuel mini-trucks emit a lot of exhaust gas, causing certain pollution to the environment. In contrast, new energy mini-trucks are driven by pure electric power, have a simple overall structure, a high degree of modularity, are more environmentally friendly, and meet the requirements of sustainable development.

[0003] However, existing new energy mini-trucks are all equipped with power battery packs and drive motors. The power battery packs are usually configured with two or four power batteries, and the power batteries are symmetrically arranged on both sides of the vehicle frame assembly. The drive motor is located between the two power batteries and drives the rear drive axle through the transmission shaft. The arrangement structure has a low degree of integration, many parts, complex structure, and large vehicle weight. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a modular frame layout structure for new energy small trucks and commercial vehicles. This makes the frame layout scheme of new energy small trucks more reasonable, safe, compact, modular, and serialized, meeting different superstructure needs. In addition, the modular design can expand the product's scope and effectively reduce product development costs and vehicle weight.

[0005] To address the problems mentioned above in the background art, this utility model is achieved through the following technical solution:

[0006] A modular frame layout structure for a new energy small truck includes a frame assembly and a cab. The cab is mounted on the upper end of the frame assembly via front and rear suspensions. The frame assembly includes a left longitudinal beam, a right longitudinal beam, and a crossbeam. The left and right longitudinal beams are connected by the crossbeam. An integrated bracket 1 and an integrated bracket 2 are provided below the cab. The integrated bracket 1 is equipped with an integrated controller and a battery. The integrated bracket 2 is equipped with a vacuum booster system, a radiator, an ABS controller, and an air conditioning compressor. The vacuum booster system is connected to the electric rear drive axle and the front steering shaft via brake lines.

[0007] Preferably, the left and right longitudinal beams are straight beams of equal width, and the vacuum assist system includes a vacuum pump and a vacuum cylinder.

[0008] Preferably, the front steering axle and the electric rear drive axle are both connected to the tires, and the brake oil pipes are respectively located at the lower end of the web surface of the left longitudinal beam and the right longitudinal beam; the front steering axle is connected to the frame assembly through the front suspension, the electric rear drive axle is connected to the frame assembly through the rear suspension, the electric rear drive axle is equipped with a drive motor, and the rear suspension of the cab is also equipped with a fender, and the fender is located above the front steering axle and the tires.

[0009] Preferably, the frame assembly is further provided with a power battery, and the lower end of the power battery is provided with a connecting plate, the upper end of the connecting plate being connected to the outer side of the left longitudinal beam and the right longitudinal beam respectively.

[0014] The power battery is located in the middle of the left and right longitudinal beams, and between the left and right longitudinal beams. The overall ground clearance is increased, which improves the collision safety of the power battery and effectively reduces the risk of bottom damage under poor road conditions. The drive motor and electric rear drive axle are integrated, saving space and freeing up space in the original transmission system to accommodate battery packs of different capacities and specifications.

[0015] The integrated controller and battery are integrated into the controller bracket and then assembled on the chassis assembly.
