A front-dash-board lower crossbeam structure and a vehicle. The front-dash-board lower crossbeam structure includes a first crossbeam layer (1) and a second crossbeam layer (2). The second crossbeam layer (2) is disposed at a side of the first crossbeam layer (1) and a hollow cavity is disposed between the second crossbeam layer (2) and the first crossbeam layer (1). When a front of the vehicle is subjected to a head-on collision, an impact force is transmitted through a left longitudinal beam and a right longitudinal beam of the vehicle frame, after the first crossbeam layer (1) and the second crossbeam layer (2) absorb a collision energy, a deformation begins to occur at the first connection section (14), the second connection section (15) and the third connection section (23). The battery pack is protected by the deformation of the first crossbeam layer (1) and the second crossbeam layer (2) and a space for the deformation provided by the hollow cavity between the first crossbeam layer (1) and the second crossbeam layer (2).
