The invention discloses a vehicle body protection structure and a vehicle. The vehicle body protection structure comprises a vehicle frame longitudinal beam, a doorsill and a protection piece. A doorsill is arranged on at least one side of the frame longitudinal beam, a first gap is formed between the frame longitudinal beam and the doorsill, and at least part of the protection piece is arranged in the first gap. The protective part is arranged between the doorsill and the longitudinal beam, side face supporting is provided for the doorsill, the possibility that the doorsill turns over and deforms in the collision process is reduced, and the doorsill can be fully crushed and deformed when bearing side face collision; meanwhile, the protection piece can transmit side collision force borne by the threshold to the frame longitudinal beam, the high-strength frame longitudinal beam is used as a main force bearing part, the collision deformation of the vehicle body can be reduced, and therefore the safety of the vehicle is effectively protected.

    本申请公开了一种车身防护结构及车辆,车身防护结构包括车架纵梁、门槛和防护件;车架纵梁的至少一侧设有门槛,车架纵梁与门槛之间形成有第一间隙,防护件至少部分设于第一间隙中。本申请通过在门槛和纵梁之间设置防护件,为门槛提供了侧面支撑,降低了门槛在碰撞过程中翻转变形的可能性,使得门槛在承受侧面碰撞时能够充分压溃变形;同时,防护件可以将门槛受到的侧面碰撞力传递至车架纵梁,通过利用高强度的车架纵梁来作为主要承力部件,能够减小车身的碰撞变形量,从而有效保护车辆的安全。
