The invention relates to a side collision reinforcing structure and a vehicle. The side collision reinforcing structure comprises a threshold reinforcing beam assembly; the B column reinforcing plate assembly is connected to the middle of the doorsill reinforcing beam assembly, and the B column reinforcing plate assembly extends upwards from the joint of the B column reinforcing plate assembly and the doorsill reinforcing beam assembly; the door frame roof side rail reinforcing plate assembly is arranged above the threshold reinforcing beam assembly, and the door frame roof side rail reinforcing plate assembly is connected with the upper end of the B column reinforcing plate assembly; the C column reinforcing plate assembly is located on one side of the threshold reinforcing beam assembly, the upper end of the C column reinforcing plate assembly is connected with the door frame roof side rail reinforcing plate assembly, and the lower end of the C column reinforcing plate assembly is connected with the threshold reinforcing beam assembly; the doorsill reinforcing beam assembly, the B column reinforcing plate assembly, the door frame roof side rail reinforcing plate assembly and the C column reinforcing plate assembly are each internally provided with a force transmission cavity, force transmission is facilitated, collision deformation is resisted, and protection is provided for passengers in the rear row.
Description
technical field [0001] The invention relates to the technical field of automobile frame, in particular to a side collision reinforcement structure and a vehicle. Background technique [0002] In recent years, as users have gradually increased their attention to passive safety of cars, the attention paid to the collision protection of rear occupants in collision safety has also gradually increased. [0003] In related technologies, in the 2018 version of C-NCAP (New Car Assessment Program, new car crash test), the inspection item for rear occupant protection has been added to the side collision. %, the weight of the barrier is increased by 47%, the body deformation is greater, the width of the barrier is increased by 200mm, and the center of impact is moved backward by 250mm in the X direction, which increases the deformation of the rear row of the vehicle, and the car body deformation in the R point area of the rear row during a side collision Larger and unable to provide...
