Vehicle and front floor assembly thereof

The invention relates to a vehicle and a front floor assembly thereof. The front floor assembly comprises a front floor (1) which is provided with a reinforcing structure (2), the reinforcing structure (2) is provided with a surface opposite to the front floor (1), and a gap is reserved between the surface and the front floor (1). By arrangement of the reinforcing structure, rigidity of the frontfloor can be improved; due to the gap between the front floor and the surface of the reinforcing structure, a cavity structure is formed between the reinforcing structure and the front floor, and accordingly vibration transmitted by cab suspension in normal operation of the vehicle is attenuated, and roar noise, caused by vibration of the front floor, in a cab is weakened; in other words, functions of vibration attenuation and noise reduction can be realized, and riding comfort is improved for passengers. 本公开涉及种车辆及其前地板总成，该前地板总成包括前地板(1)，其中，所述前地板(1)上设置有加强结构(2)，该加强结构(2)具有与所述前地板(1)相对的表面，该表面与所述前地板(1)之间具有间隙。通过加强结构的设置，能够提高前地
