The invention discloses a quick-change support and an electric automobile, the quick-change support comprises a longitudinal beam, a cross beam and an adapter, the cross beam comprises a cross beam body, the longitudinal beam comprises a longitudinal beam body, and the cross beam body and the longitudinal beam body are at least partially made of profiles; the longitudinal beam body and the cross beam body are connected into a frame structure through the adapter piece, and the adapter piece comprises a first connecting part and a second connecting part which are connected with each other; the first connecting part and the second connecting part respectively extend into the longitudinal beam body and the cross beam body and are detachably connected with the longitudinal beam body and the cross beam body at the corresponding positions. According to the quick-change support, the structural strength is guaranteed, meanwhile, quick and accurate alignment connection of the cross beams and the longitudinal beams is achieved through the connectors, the manufacturing process of the quick-change support is simple, the number of steps is small, the manufacturing period is shortened, and due to the fact that a reinforcing structure does not need to be welded, the size accuracy of the quick-change support after splicing is improved.

    本发明公开了一种快换支架及电动汽车,所述快换支架包括纵梁、横梁与转接件,所述横梁包括横梁本体,所述纵梁包括纵梁本体,所述横梁本体与纵梁本体至少部分由型材制成;所述纵梁本体与所述横梁本体之间通过所述转接件连接成一框架结构,所述转接件包括相互连接的第一连接部与第二连接部,所述第一连接部与第二连接部分别伸入所述纵梁本体内和所述横梁本体内并与对应处的所述纵梁本体和横梁本体可拆卸连接。快换支架在保证结构强度的同时,采用转接件实现横梁与纵梁的快速、精确对准连接,快换支架的制造过程简单、步骤少,制造周期缩短,而且由于无需焊接加强结构,提高快换支架的拼接后的尺寸精度。
