The invention provides an edge beam for a quick-change support, the quick-change support and an electric vehicle. The edge beam for the quick-change support comprises a first installation face facing the battery pack and a second installation face facing the bottom of the electric automobile, and the first installation face is connected with a locking mechanism used for locking the battery pack. The edge beam for the quick-change support is made of sectional materials and provided with at least two cavities, the at least two cavities comprise the first cavity located on the back face of the first installation face and the second cavity located on the back face of the second installation face, and the first cavity and the second cavity extend in the length direction of the edge beam for the quick-change support. The boundary beam for the quick-change support does not need to be additionally welded with a reinforcing structure to meet the strength requirement, is convenient to machine, shortens the construction period, is high in size precision and meets the assembly precision requirement between the quick-change support and a battery.
本发明提供一种快换支架用边梁、快换支架及电动汽车。快换支架用边梁包括朝向电池包的第一安装面以及朝向电动汽车底部的第二安装面,第一安装面连接有用于锁止电池包的锁止机构。快换支架用边梁由型材制成,且具有至少两个型腔,至少两个型腔包括位于第一安装面的背面的第一型腔和位于第二安装面的背面的第二型腔,第一型腔和第二型腔均沿着快换支架用边梁的长度方向延伸。该快换支架用边梁无需额外焊接加强结构以满足强度要求,便于加工从而缩短工期,尺寸精度较高,满足快换支架与电池之间的装配精度要求。
