The invention relates to a vehicle body forecabin structure and a vehicle. The vehicle body forecabin structure comprises a side longitudinal beam group; an upper longitudinal beam group; the A column area comprises a side wall outer plate and a T-shaped reinforcing plate, the T-shaped reinforcing plate is located on the inner side of the side wall outer plate, the T-shaped reinforcing plate comprises a vertical reinforcing plate and a transverse reinforcing plate, the upper longitudinal beam set is arranged on the upper portion area of the vertical reinforcing plate, the transverse reinforcing plate is fixed to the outer side of the side longitudinal beam set, and the side wall outer plate is arranged on the side wall outer plate. Partial area of the transverse reinforcing plate extends to the outer side of the side wall outer plate; one end of the first supporting plate is fixed to the vertical reinforcing plate, the other end of the first supporting plate is fixed to the upper longitudinal beam set, and a triangular structure is defined by the first supporting plate, the vertical reinforcing plate and the upper longitudinal beam set; one end of the second supporting plate is fixed to the baffle, and the other end of the second supporting plate is fixed to the vertical reinforcing plate. Through structural arrangement optimization, a stress node, a stress area and a frame structure are formed, the stress path of the vehicle body forecabin area is optimized, and the mechanical property and the collision safety performance of the vehicle body forecabin area are improved.
