The invention relates to a collet device, a power battery box assembly and a battery changing vehicle. The bottom support device is used for supporting and limiting a battery box frame and comprises a bottom support frame, a plurality of locking seats, a locking assembly, a charging and discharging assembly and a buffering assembly. The bottom support device further comprises floating limiting assemblies, the surfaces, exceeding the locking seats, of the floating limiting assemblies are cylindrical surfaces, and the floating limiting assemblies installed on the locking seats form a floating adjusting area protruding towards the periphery of the bottom support frame. Wherein the battery box frame is erected on the bottom support frame, the cylindrical surface abuts against the bottom support frame, the floating adjusting area is used for limiting the circumferential installation position of the battery box frame in a floating mode, and the locking assembly is used for limiting the longitudinal installation position of the battery box frame. The bottom support frame dynamically positions the transverse installation position of the battery box frame through the floating limiting assemblies distributed on the locking seats, and therefore transverse centering adjustment and overall balance of the battery box frame are achieved.

    本发明涉及一种底托装置、动力电池箱总成及换电车辆。底托装置用于支撑及限定电池箱框架,所述底托装置包括底托框架、多个锁止座、锁止组件、充放电组件及缓冲组件。底托装置还包括浮动限位组件,所述浮动限位组件超出所述锁止座的表面设置为圆柱面,多个所述锁止座所安装的浮动限位组件构成向所述底托框架的外周凸出的浮动调节区域。其中,所述电池箱框架架设于所述底托框架,所述圆柱面抵接于所述底托框架,所述浮动调节区域用于浮动限定所述电池箱框架的周向安装位置,所述锁止组件用于限定所述电池箱框架的纵向安装位置。底托框架通过分布于锁止座的浮动限位组件进行动态定位电池箱框架的横向安装位置,从而实现电池箱框架的横向对中调节及整体平衡。
