The invention belongs to the technical field of electric vehicle battery pack installation, and particularly relates to a battery pack rear installation point fixing structure. Comprising two installation supports, a first pipe fitting, a second pipe fitting, a third pipe fitting, a fourth pipe fitting and two fifth pipe fittings, and the structure is fixed to the lower portion of a middle floor of a vehicle. The battery pack mounting structure is simple in connecting process, convenient to fix with a vehicle body, high in mounting precision, convenient for subsequent mounting of the battery pack, light in weight and low in cost. The structural rigidity is good, and the local rigidity of a battery pack mounting point and the torsional rigidity of a middle floor area can be remarkably enhanced.

本发明属于电动汽车电池包安装技术领域，具体涉及一种电池包后部安装点固定结构；包括两个安装支架、一根第一管件、一根第二管件、一根第三管件、一根第四管件以及两根第五管件，所述结构固定在车辆中地板下部；本发明的电池包安装结构连接工艺简单，便于与车身固定，安装精度高，便于后续电池包的安装，重量轻，成本低。本结构刚度好，能够显著加强电池包安装点的局部刚度及中地板区域的扭转刚度。
