The invention relates to the field of battery replacement power battery assemblies, in particular to a heavy truck battery replacement power battery assembly which comprises a battery pack locking frame, a battery replacement connector, a locking mechanism and a battery pack. The transfer pressing oil cylinder drives the pressing plate on the transfer pressing oil cylinder to rotate and press downwards, so that the pressing plate on the transfer pressing oil cylinder is pressed on the battery pack, the transfer pressing oil cylinder is a hydraulic cylinder, and compared with an air cylinder for pressing, the pressing of the battery pack is tighter, the battery pack is prevented from moving upwards, and the battery pack is prevented from moving upwards. Therefore, faults caused by the fact that a plug of the battery pack cannot be tightly inserted into the battery replacing connector are avoided, and if a pressing mechanism is replaced with a clamping mechanism, faults still occur due to the fact that a tilting gap is generated between the bottom of the battery pack and the top of a battery pack locking frame due to machining, and gas interruption occurs during actual pressing of an air cylinder are avoided.
本发明涉及换电动力电池总成领域,具体涉及一种重卡换电动力电池总成,包括电池包锁固框架、换电连接器、锁固机构和电池包,该重卡换电动力电池总成,通过控制器控制转交下压油缸进行工作,使得转交下压油缸带动转交下压油缸上的压板进行转动下压,进而使得转交下压油缸上的压板压紧在电池包上,通过转交下压油缸是液压缸,相比于通过气缸进行压紧,使得对电池包的压紧更加紧密,避免电池包向上运动,进而避免电池包的插头无法紧密的插在换电连接器上,而造成的故障,且若是将压紧机构更换成卡紧机构,由于电池包底部与电池包锁固框架顶部之间会由于加工产生翘起间隙,还是会发生故障,并且气缸在实际压紧时,会产生断气的故障。
