Abstract

The invention relates to an electric non-bearing vehicle body comprising a vehicle frame and a vehicle body connected to the vehicle frame. The vehicle frame specifically comprises longitudinal beamsarranged on the two sides, front end structures, middle structures and rear end structures, wherein the front end structures, the middle structures and the rear end structures are arranged on the front portions, the middle portions and the rear portions of the longitudinal beams on the two sides respectively. The vehicle body comprises a vehicle main body composed of a front wall, a rear wall, a top cover, floors and B columns. The engine room position of the vehicle body is only composed of an engine room edge beam and a water tank supporting part, so that the vehicle body is simple in structure and low in weight; besides, two motor mounting brackets are arranged on the longitudinal beams on the two sides, so that the motor shell can play a role of a cross beam due to the mounting of themotor on the motor mounting brackets; besides, the frame cross beam is formed by a power battery pack shell fixedly connected with the longitudinal beams on the two sides; meanwhile, an existing framecross beam can be omitted, the overall weight of the frame is reduced, so that the lightweight design of a vehicle body can be facilitated.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric non-load-bearing vehicle body. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, electric vehicles are getting more and more attention. For electric vehicles, their overall weight plays an important role in energy consumption and performance. Since the conventional frame in the prior art usually has both longitudinal beams and cross beams, and the motor is usually installed on the cross beam or sub-frame, the frame cross beam structure is not conducive to the arrangement of the battery pack, so the conventional frame form is not suitable for new Energy vehicles are equipped with heavy weight, which is not conducive to lightweight design, which will lead to more energy consumption of electric vehicles and a decrease in cruising range. Contents of the invention [0003] In view of this, the prese...
