The invention relates to a lower vehicle body structure of a commercial vehicle and the commercial vehicle, and the lower vehicle body structure of the commercial vehicle comprises a vehicle frame which comprises a first longitudinal beam, a second longitudinal beam and a mounting beam; one end of the mounting beam is connected with the first longitudinal beam, the other end of the mounting beam is connected with the second longitudinal beam, the middle area of the mounting beam arches upwards to form a mounting part, and the mounting part is higher than the first longitudinal beam and the second longitudinal beam; and the hydrogen storage assembly is mounted at the bottom of the mounting part. The hydrogen storage assembly is mounted on the mounting beam, and the mounting beam is arranged between the first longitudinal beam and the second longitudinal beam. The installation of the hydrogen storage assembly does not occupy the installation space on the longitudinal beam of the frame, and the arrangement of large-size components such as the battery assembly and the exhaust assembly on the frame is facilitated. Meanwhile, the hydrogen storage assembly is located between the two longitudinal beams and installed on the installation part higher than the first longitudinal beam and the second longitudinal beam, the ground clearance of the hydrogen storage assembly is increased, and the safety performance of the hydrogen storage assembly is improved.
本发明涉及一种商用车下车体结构及商用车,其中,商用车下车体结构包括:车架,所述车架包括第一纵梁、第二纵梁以及安装梁;所述安装梁的一端与所述第一纵梁相连,另一端与所述第二纵梁相连,且所述安装梁的中间区域向上拱起形成安装部,所述安装部高于第一纵梁及第二纵梁;储氢总成,所述储氢总成安装于所述安装部的底部。由于储氢总成安装于安装梁上,安装梁设于第一纵梁与第二纵梁之间。储氢总成的安装并不会占用车架纵梁上的安装空间,便于电池总成、排气总成等大体积部件在车架上的布置。同时,由于储氢总成位于两纵梁之间,且安装于高于第一纵梁及第二纵梁的安装部,抬高了储氢总成的离地高度,提高了储氢总成的安全性能。
