Mounting rack for battery pack, and vehicle

A vehicle, comprising:

• a vehicle body;
• two chassis beams connected to a bottom of the vehicle body;
• a mounting rack for a battery pack, the mounting rack being mounted at the two chassis beams, the mounting rack having a first direction consistent with an extending direction of the chassis beams and a second direction perpendicular to the first direction, the mounting rack comprising:
• a first assembly unit adapted to be mounted between two chassis beams, wherein the first assembly unit comprises:
• at least two first transverse beams arranged at intervals in the first direction, two ends of each of the at least two first transverse beams being adapted to be connected to the two chassis beams, respectively;
• at least two first longitudinal beams, each of the at least two first longitudinal beams being arranged between every two adjacent first transverse beams of the at least two first transverse beams, the every two adjacent first transverse beams and the two chassis beams located between the every two adjacent first transverse beams defining a first accommodation cavity configured to mount a fixing block of the battery pack, and the at least two first longitudinal beams being arranged in the first accommodation cavity and connected to the two chassis beams, respectively;
• and
• a first assembly member connected to the battery pack;
• a second assembly unit adapted to be mounted at a side of each of the two chassis beams facing away from the first assembly unit, the second assembly unit comprising:
• at least two second transverse beams arranged at intervals in the first direction, each of the at least two second transverse beams having an end adapted to be connected to the chassis beam;
• an outer side beam connected to an end of each of the at least two second transverse beams facing away from the chassis beam, wherein every two adjacent second transverse beams of the at least two second transverse beams, the chassis beam located between the every two adjacent second transverse beams, and the outer side beam define a second accommodation cavity configured to mount a fixing block of the battery pack;
• and
• a second longitudinal beam arranged between the every two adjacent second transverse beams, the second longitudinal beam being connected to the chassis beam and located in the second accommodation cavity;
• and
• a second assembly member connected to the battery pack,
• wherein each of the two chassis beams is provided with at least one of the first longitudinal beam and the second longitudinal beam.
