The invention discloses a side beam of a quick-change support, the quick-change support and an electric automobile, the quick-change support is arranged on the electric automobile and used for installing a battery pack, the side beam of the quick-change support comprises an inner side beam and an outer side beam, the outer side beam comprises a connecting part and a reinforcing part, and the extending direction of the connecting part is the same as that of the inner side beam; the reinforcing part protrudes in the direction away from the inner side beam relative to the connecting part, and the connecting part is fixedly connected with the inner side beam through spot welding. Due to the fact that spot welding has little influence on the structure, deformation of the outer side beam and the inner side beam in the welding process can be reduced, the overall structure of the side beam formed after the outer side beam and the inner side beam are assembled and fixed meets the design requirement, the accuracy of the side beam is guaranteed, and the production efficiency is improved. And mutual alignment of the battery pack and the side beam and mutual alignment of the electric vehicle and the side beam are ensured. And after the inner side beam and the connecting part are subjected to spot welding, a reinforcing structure is naturally formed between the inner side beam and the outer side beam, so that the mounting efficiency is improved while the structure of the side beam is reinforced.
本发明公开了一种快换支架的侧梁、快换支架和电动汽车,快换支架设于电动汽车上并用于安装电池包,快换支架的侧梁包括内侧梁和外侧梁,外侧梁包括连接部和加强部,连接部与内侧梁的延伸方向相同,加强部相对于连接部朝远离内侧梁的方向凸出,连接部与内侧梁通过点焊固定连接。由于点焊对于结构的影响较小,可以减少外侧梁和内侧梁在焊接时的变形,进而使得外侧梁和内侧梁拼装固定后形成的侧梁的整体结构符合设计要求,有利于保证侧梁的精确度,也就有利于保证电池包与侧梁相互对准、电动汽车与侧梁相互对准。并且当内侧梁与连接部点焊后,内侧梁与外侧梁之间自然形成了加强结构,实现了侧梁的结构得以加强的同时,还提高了安装效率。
