The invention relates to a lower vehicle body floor arrangement structure for an extended-range electric commercial vehicle, and belongs to the technical field of automobile floors. The lower vehicle body floor arrangement structure comprises a floor frame which comprises a left longitudinal beam, a right longitudinal beam and a rear cross beam connected between the left longitudinal beam and the right longitudinal beam, and a floor body which comprises a floor central channel which is located between the left longitudinal beam and the right longitudinal beam and protrudes upwards, and the rear end of the floor central channel is fixedly connected with the rear cross beam; the lower vehicle body floor arrangement structure further comprises a power battery which is fixedly arranged below the floor central channel in the horizontal direction, and a transverse through space is preset between the power battery and the rear cross beam; the lower vehicle body floor arrangement structure further comprises a reinforcing assembly which comprises a reinforcing cross beam which is located in the transverse through space and connects the two sides of the floor central channel into a whole, and a plurality of steel plate reinforcing ribs which are arranged at intervals are fixedly arranged in the rear cross beam in the length direction of the rear cross beam. According to the reinforcing assembly, the rigidity of the lower vehicle body floor of the vehicle body is integrally improved, the modality of the lower vehicle body floor of the vehicle body is improved, and the problems of abnormal sound and shaking of the lower vehicle body floor of the vehicle body are avoided.
Description
technical field [0001] The present application relates to the field of automobile floor technology, in particular to an arrangement structure of a lower body floor for an extended-range electric commercial vehicle. Background technique [0002] With the significant improvement of people's living standards, people have higher and higher requirements for the comfort of cars. In order to meet customer needs and enhance brand competitiveness in the market, various automobile manufacturers continue to optimize the body structure to achieve the best vehicle NVH performance under the premise of controlling the design cost to be the lowest. The underbody directly affects the passengers' subjective perception of the vibration and noise of the vehicle body, and its vibration and noise transfer function has a great influence on the ride comfort of the car. Insufficient rigidity of the car body under the car body is likely to cause body vibration and roaring, which greatly reduces the ...
