The invention discloses a battery pack hanging point structure of an electric vehicle, which aims to overcome the defects that a battery pack of an existing electric vehicle adopts a cross beam type hanging mode, the vibration mode is low, and the stability is poor. A battery pack hanging point structure of an electric vehicle is characterized in that batteries in a battery pack are arranged in an array mode and are in bilateral symmetry along the longitudinal central axis of the battery pack, end plates are arranged at the two ends of every two adjacent batteries in the transverse direction, the end plates corresponding to the central axis are fixedly connected with positioning longitudinal beams through fasteners, and the positioning longitudinal beams are fixedly connected with a vehicle body front floor. The positioning longitudinal beams optimize the overall vibration mode, disperse the stress of the battery pack box body and improve the safety of the electric vehicle, the longitudinal beams replace cross beams, the layout space of the battery pack is optimized, and the electric power of the battery pack is improved.
本发明公开了一种电动汽车电池包挂点结构,旨在解决现在的电动汽车的电池包采用横梁式的挂载方式,振动模态偏低,稳定性差的不足。一种电动汽车电池包挂点结构,电池包中的电池阵列排布并沿电池包纵向的中轴线左右对称,相邻电池横向方向的两端设有端板,中轴线位置对应的端板上经紧固件固定连接有定位纵梁,定位纵梁固定连接车身前地板。定位纵梁优化整体振动模态,分散电池包箱体的应力,提高电动汽车的安全性,以纵梁取代横梁,优化了电池包的布局空间,提高了电池包的电力。
