Vehicle body structure and automobile

Abstract

The present application discloses a vehicle body structure and an automobile, relating to the technical field of vehicle bodies. The vehicle body structure includes: a side reinforcement plate connected to the vehicle's side outer panel; a side inner panel connected to the inner side of the side reinforcement plate, the side inner panel and the side reinforcement plate forming a first buffer cavity at the bottom corresponding to the vehicle pillar; a floor assembly connected to the side reinforcement plate and the side inner panel, the floor assembly and the side reinforcement plate forming a second buffer cavity at the vehicle's door sill; an energy absorption assembly disposed in the first and second buffer cavities, the energy absorption assembly being configured to collapse and absorb energy during a collision; and a lateral support member connected to the floor assembly and the side inner panel. The side reinforcement plate is disposed between the side outer panel and the side inner panel, thereby enhancing the overall strength of the vehicle body side. The simultaneous connection of the side reinforcement plate and the side inner panel to the floor assembly increases the number of collision stress points on the vehicle body side.
