The beam body 100 of the cross beam structure at the bottom in the second direction is a friction beam, and the beam body 100 of the remaining two cross beam structures in the plurality of groups of the cross beam structure is a crash beam. The friction force between the friction beam and the vehicle is greater than the friction force between the crash beam and the vehicle, and the strength of the crash beam is greater than the strength of the friction beam.
