The invention discloses an upper longitudinal beam structure assembly, a vehicle body and a vehicle, and belongs to the technical field of vehicle bodies in white. An upper metal plate of the upper longitudinal beam structure assembly and the shock absorption tower are designed in a shape follow-up mode, and the Z-direction height of the section is compressed; the support, the gas spring, the buffer block, the hinge and other parts are all connected to the side face, and the collision deformation space between the engine cover and the shotgun is increased; the front fender support is welded to the lower inclined strut beam structure, the Z-direction height is reduced, a cantilever structure is adopted, overturning deformation occurs during collision, and head injuries are reduced; the middle fender support is of a U-shaped structure, the side wall structure of the engine cover is effectively avoided, the middle fender support can be crushed in time during collision, and therefore it is guaranteed that the engine cover deforms sufficiently; the arrangement positions of the hinge and the mounting bracket are optimized, an avoiding structure is added, and head injury in the area is weakened; the problem that the new energy vehicle engine cover height and the vehicle pedestrian protection performance cannot be considered at the same time is solved.

    本发明公开了一种上纵梁结构总成、车身及车辆,属于汽车白车身技术领域。上纵梁结构总成的上部钣金通过与减震塔随型设计,压缩截面Z向高度;将支架、气弹簧、缓冲块、铰链等部件全部连接在侧面,增加发动机盖到shotgun之间的碰撞变形空间;前部翼子板支架焊接到下方的斜撑梁结构上,降低Z向高度,并采用悬臂结构,碰撞时发生翻转变形,减少头部伤害;中部翼子板支架采用U字形结构,有效避让开发动机盖侧壁结构,并且碰撞时可以及时被压溃,从而保证发动机盖充分变形;优化铰链及安装支架布置位置,增加避让结构,减弱该区域的头部伤害;解决新能源车辆发动机盖高度与汽车行人保护性能无法兼顾的问题。
