The invention relates to a vehicle body supporting frame assembly, a vehicle body structure assembly and a vehicle. The vehicle body supporting frame assembly comprises a first supporting frame and a second supporting frame, the first supporting frame is suitable for being connected between the left side wall and the right side wall so as to support a vehicle body in the first direction, and the second supporting frame and the first supporting frame are arranged in a spaced mode and suitable for being connected between at least one of the left side wall and the right side wall and the top cover. And a support to support the vehicle body in a second direction, where the first direction intersects the second direction. The first supporting frame and the second supporting frame in the vehicle body supporting frame assembly can support the vehicle body in different directions, the torsional rigidity and the flexural rigidity of the vehicle body can be improved to a great extent, the vehicle body supporting frame assembly is simple in structural form, light-weight design is achieved while the function and performance requirements of the vehicle body are met, and the vehicle body supporting frame assembly is suitable for large-scale popularization and application. The production process rhythm is met and the manufacturing cost is reduced.
本申请涉及一种车身支撑架总成、车身结构总成及交通工具。车身支撑架总成包括第一支撑架以及第二支撑架,第一支撑架适于连接于左侧围与右侧围之间,以在第一方向上支撑车身,第二支撑架与第一支撑架间隔设置,并适于连接于左侧围、右侧围中的至少一者与顶盖之间,以在第二方向上支撑车身,其中,第一方向与第二方向相交。上述车身支撑架总成中的第一支撑架与第二支撑架能够在不同方向上支撑车身,还能够在很大程度上提升车身的扭转刚度和抗弯刚度,在满足车身功能和性能需求的同时,车身支撑架总成结构形式简单,实现轻量化设计,满足生产工艺节拍,降低制造成本。
