Subframe and vehicle

Abstract

The utility model discloses a kind of auxiliary frame and vehicle, auxiliary frame includes: two frame longitudinal beam assemblies, two frame longitudinal beam assemblies are spaced apart along vehicle transverse distribution;Frame middle crossbeam and frame rear crossbeam, frame middle crossbeam and frame rear crossbeam are spaced apart along front and back direction and are connected between two frame longitudinal beam assemblies, to jointly define first weight-reducing cavity;At least one intermediate support plate, at least one intermediate support plate is connected between frame middle crossbeam and frame rear crossbeam, and at least part of intermediate support plate is located in first weight-reducing cavity.The auxiliary frame of the utility model embodiment, the weight of auxiliary frame can be reduced by first weight-reducing cavity, conducive to the setting of auxiliary frame on vehicle, and can improve the endurance of new energy vehicle type, and, at least part of intermediate support plate is located in first weight-reducing cavity, can improve the structural strength of auxiliary frame at first weight-reducing cavity, avoid the structural strength of auxiliary frame to be reduced due to the setting of first weight-reducing cavity.
