The van vehicle has the advantages of flexibility, convenient operation, high efficiency in work, large transportation capacity, full utilization of space, safety, reliability and the like in the transportation process. The traditional van is a fuel vehicle, has the advantages of sufficient power, long driving mileage and convenient oiling, so that the carriage is generally manufactured by adopting an iron corrugated plate, the carriage has heavy weight, the cruising mileage of a new energy automobile is short, the requirement of the new energy automobile on the blue plate cannot be met, and the van cannot be used on an electric new energy automobile. In addition, the energy-saving and environment-friendly requirements of the cities in various places are higher and higher at present, and more new energy logistics vehicles are needed in the express logistics industry to meet the use requirements of the new energy logistics vehicles.

The Chinese patent document with the publication number of CN106394706A discloses a logistics vehicle and a carriage thereof, the logistics vehicle comprises a carriage body, the carriage body comprises a carriage plate assembly, a chassis assembly, a skirt edge assembly and a rear door plate assembly, the carriage plate assembly is arranged above the chassis assembly, the skirt edge assembly is arranged below the chassis assembly, and the rear door plate assembly is connected with the carriage plate assembly, the chassis assembly and the skirt edge assembly simultaneously; the logistics vehicle comprises the carriage. The invention has simple structure, lower dead weight and convenient assembly, thereby the carriage can be applied to new energy vehicles, but the new energy logistics carriage has the following technical defects:
