The invention relates to the technical field of electric automobiles, in particular to a quick-change locking mechanism, an electric automobile chassis and an electric automobile. The quick-change locking mechanism comprises a driving part and a locking assembly, the locking assembly comprises a supporting shaft, a locking part and an elastic part, the supporting shaft is fixed to the chassis frame, the supporting shaft is rotatably sleeved with the locking part, the supporting shaft is sleeved with the elastic part, and the elastic part is located between the chassis frame and the locking part. The output end of the driving part is in transmission connection with one end of the locking part, the other end of the locking part is provided with a protrusion capable of being matched with a mounting hole of a battery pack, and the driving part can drive the locking part to rotate around the supporting shaft so that the protrusion can be clamped in the mounting hole of the battery pack or disengaged from the mounting hole of the battery pack, and therefore the rapid disassembly and assembly of the battery pack are achieved. The operation is convenient and the stability is good. According to the electric automobile chassis, the battery pack can be quickly disassembled and assembled. According to the electric automobile, the battery pack can be conveniently and rapidly replaced, modularization and platformization can be achieved, and the cost is reduced.

    本发明涉及电动汽车技术领域,尤其涉及一种快换锁紧机构、电动汽车底盘及电动汽车。所述快换锁紧机构包括驱动件和锁紧组件,锁紧组件包括支撑轴、锁紧件和弹性件,支撑轴固定在底盘框架上,锁紧件可转动地套设在支撑轴上,弹性件套设在支撑轴上且位于底盘框架与锁紧件之间,驱动件的输出端与锁紧件的一端传动连接,锁紧件的另一端设置有能够与电池包的安装孔相配合的凸起,驱动件能够驱动锁紧件绕支撑轴转动,以使凸起卡设在电池包的安装孔内或与电池包的安装孔脱离,从而实现电池包的快速拆装,且便于操作,稳定性好。所述电动汽车底盘能够实现电池包的快速拆装。所述电动汽车便于快速更换电池包,有利于实现模块化及平台化,降低成本。
