The invention relates to the field of battery replacement of electric vehicles, and provides a quick replacement device and a battery replacement vehicle comprising the same. The quick-change device comprises a spherical hinge bearing assembly and a quick-change support, the quick-change support is used for installing a battery pack, the spherical hinge bearing assembly is connected between the quick-change support and a vehicle body girder of the battery changing vehicle, and at least one side of the quick-change support is in floating connection with the vehicle body girder through the spherical hinge bearing assembly. The spherical hinge bearing assembly is connected between the quick-changing support and the vehicle body girder of the battery-changing vehicle, so that the quick-changing support and the vehicle body girder are not in direct rigid connection, and when the vehicle body girder of the battery-changing vehicle is twisted when passing through an abrupt slope, a water pit, a slope and the like, the spherical hinge bearing assembly can convert the torque of the vehicle body girder; the quick-change support can move relative to the vehicle body girder, and the situation that the torque of the vehicle body girder is directly transmitted to the quick-change support and then transmitted to the battery pack installed on the quick-change support, and consequently the battery pack is damaged is avoided.
本发明涉及电动车换电领域,提供了一种快换装置及包含其的换电车辆。所述快换装置包括球铰轴承组件和快换支架,所述快换支架用于安装电池包,所述球铰轴承组件连接于所述快换支架与所述换电车辆的车身大梁之间,所述快换支架的至少一侧通过所述球铰轴承组件与所述车身大梁浮动连接。在快换支架与换电车辆的车身大梁之间连接球铰轴承组件,使快换支架与车身大梁之间不是直接的刚性连接,换电车辆的车身大梁在经过陡坡、水坑、斜坡等产生扭转时,球铰轴承组件可以转化车身大梁的扭矩,使快换支架能够相对于车身大梁发生位移,避免车身大梁的扭矩直接传递到快换支架,进而传递到安装于快换支架上的电池包,造成电池包损坏。
