The invention discloses a positioning and locking device for a battery replacement type battery box. The positioning and locking device comprises the battery replacement type battery box, a vehicle-mounted battery replacement base and locking mechanisms; the battery replacement type battery box is defined by a plurality of frames and is used for mounting a power battery; and the vehicle-mounted battery replacement base is fixedly installed on an electric vehicle, at least one group of diagonal positions of the vehicle-mounted battery replacement base are provided with first-stage guide components, the vehicle-mounted battery replacement base is further provided with the plurality of locking mechanisms, each locking mechanism is composed of a lock body, a push-pull structure and an eccentric wheel, and the push-pull structures push the eccentric wheels to move so as to press the lock bodies, so when the battery replacement type battery box is mounted on the vehicle-mounted battery replacement base through the first-stage guide components, the locking mechanisms lock the bottom frame of the battery replacement type battery box. According to the technical scheme, the problem that the positioning precision of replacement operation of the power battery box of the electric heavy truck is poor is solved, and the mounting stability of the power battery box in the electric heavy truck is improved.

    本申请公开了一种换电式电池箱定位锁紧装置,该定位锁紧装置包括:换电式电池箱,车载换电底座以及锁紧机构;换电式电池箱由多个边框围成,换电式电池箱用于安装动力电池;车载换电底座固定安装于电动汽车上,车载换电底座的至少一组对角位置设置有一级导向部件,车载换电底座上还设置有多个锁紧机构,该锁紧机构由锁体、推拉结构以及偏心轮构成,由推拉结构推动偏心轮运动以压紧锁体,使得锁紧机构在换电式电池箱通过一级导向部件安装在车载换电底座上时,锁紧换电式电池箱的底部边框。通过本申请中的技术方案,解决电动重型卡车动力电池箱更换作业定位精度差的问题,并提高电动重型卡车中动力电池箱安装的稳定性。
