Pure electric minicar chassis arranging structure

The utility model discloses a pure electric minicar chassis arranging structure which comprises a square truss. The square truss protrudes in a passenger compartment direction. The front portion of the square truss is fixed on a middle horizontal beam of a car body. The back portion of the square truss is fixed on a back horizontal beam of the car body. A power battery pack assembly is arranged in the square truss. A low-voltage module is in a front compartment frame. A high-voltage module is placed in a back compartment frame. Cooling water pipes, braking steel pipes and parking braking soft shafts are arranged on the two sides of the power battery pack assembly. The arranging spaces of electric car high-low electric devices are independent, electromagnetic interference is lowered, meanwhile, a battery pack is arranged through the brand-new regular frame-shaped truss, the safe ground clearance of the battery pack is guaranteed, meanwhile, whole car passing ability and passenger comfort are guaranteed, the battery capacity of the battery pack is improved, and the whole car driving range is improved. A rear-engine rear-drive arranging mode is used in a power driving system assembly, the grade ability of a pure electric minicar is effectively improved, and meanwhile 50 : 50 ideal distribution of the front-back axle load is achieved on the whole car.
