The invention relates to a quick mounting structure for a power battery of a pure electric vehicle. The quick mounting structure comprises a mounting structure assembly and a fixed bracket assembly, the installation structure assembly is fixed to the power battery assembly, the fixing support assembly is fixed to the vehicle body longitudinal beam assembly, and the installation structure assembly is matched with the fixing support assembly in a clamped mode. According to the technical scheme, rapid assembly of the power battery is achieved, meanwhile, the requirement for manufacturing precision is lowered, manufacturing difficulty is lowered, the structure is simple and compact, cost is low, and the problems that an existing pure electric vehicle power battery is fixed to a vehicle body longitudinal beam through six-point 12 bolts, the error between a fixing support and a vehicle body longitudinal beam fixing nut cannot be too large, and cost is low are solved. The invention aims to solve the problems of high manufacturing precision requirement, high manufacturing difficulty, difficulty in assembly and disassembly, high manufacturing cost and the like of the power battery, and realizes quick assembly, convenience in battery replacement operation of the power battery, reduction of charging waiting time and reduction of manufacturing, use and maintenance costs of the whole vehicle.

    本发明涉及一种纯电动汽车动力电池的快速安装结构,包括安装结构总成及固定支架总成;安装结构总成固定于动力电池总成上,固定支架总成固定于车身纵梁总成上,安装结构总成与所述固定支架总成卡接配合。本技术方案实现动力电池的快速装配,同时降低了对制造精度的要求,降低了制造难度,结构简单紧凑,成本较低,解决了现纯电动汽车动力电池采用六点共12个螺栓固定在车身纵梁上,固定支架和车身纵梁固定螺母间的误差不能太大,对两者的制造精度要求较高,制造难度较大,同时需要12个螺栓固定,装拆较为困难,制造成本较高等问题,实现快速装配,便于动力电池的换电操作,减少充电等待时间,降低整车的制造、使用及维护费用。
