The invention relates to the technical field of vehicles, in particular to an A column structure for a vehicle, a vehicle body structure and the vehicle, and aims to solve the technical problem that the sealing performance between an A column reinforcing plate and a side wall outer plate is poor under the condition that an A column moves forwards. In order to achieve the purpose, the A column structure comprises a doorsill beam, an A column body, an A column reinforcing plate and a side wall outer plate. The bottom of the A column body is connected to a doorsill beam; the A column reinforcing plate is connected to the front end of the A column body, and the front end of the A column reinforcing plate is arranged ahead of the front end of the threshold beam in the length direction of the vehicle; the side wall outer plate is arranged on the outer sides of the threshold beam, the A column body and the A column reinforcing plate, the threshold beam, the A column body and the A column reinforcing plate are all connected with the side wall outer plate, the front end of the side wall outer plate is located between the front end of the A column reinforcing plate and the front end of the threshold beam in the length direction of a vehicle, and the top of the side wall outer plate is in lap joint with the A column reinforcing plate. Therefore, the side wall outer plate, the A column reinforcing plate and the A column body form a stable sealing structure.

    本发明涉及车辆技术领域,具体提供一种用于车辆的A柱结构、车身结构及车辆,旨在解决在A柱前移的情况下A柱加强板与侧围外板之间密封性较差的技术问题。为此目的,本发明提供的A柱结构包括门槛梁、A柱本体、A柱加强板及侧围外板。A柱本体的底部连接于门槛梁;A柱加强板连接于A柱本体的前端,沿车辆长度方向,A柱加强板的前端超前门槛梁的前端设置;侧围外板设置于门槛梁、A柱本体及A柱加强板的外侧,且门槛梁、A柱本体及A柱加强板均与侧围外板相连,沿车辆长度方向,侧围外板的前端位于A柱加强板的前端与门槛梁的前端之间,侧围外板的顶部搭接于A柱加强板,以使侧围外板、A柱加强板与A柱本体形成稳定密封结构。
