Background

In order to improve the safety of the front offset collision of the vehicle and protect the safety of passengers to the maximum extent, the small offset front collision of the vehicle is paid more and more attention in the field of automobile safety. When the design is carried out under the condition of small offset frontal collision, the overlapping amount of the front part of the vehicle and the rigid barrier accounts for 25 percent of the width of the vehicle, the rigid barrier collides with the barrier at the speed of 64km/h, and the deformation of a passenger compartment is required to be incapable of large invasion deformation after the collision. However, since the overlapping amount is small, the tire and the barrier press the front part of the threshold, and the threshold is easy to bend and deform, in the related art, the rigidity of the cross section of the threshold is discontinuous due to the fact that the reinforcing parts are respectively arranged on the inner plate and the outer plate of the threshold, the threshold is prone to flattening and torsional deformation, and accordingly, the threshold causes great damage to passengers in the vehicle.
