The invention relates to a battery replacing system for engineering machinery, which comprises a rear frame, a battery replacing connector base and a battery system frame, the battery system frame comprises a first part, a second part and a third part, the first part is arranged above the rear frame, the battery replacing connector base is arranged on the rear frame and is positioned below the first part, and the second part is arranged below the third part. The second part and the third part are located on the two sides of the rear frame respectively, the first part comprises at least one layer of battery box frame, a battery locking mechanism is arranged between the rear frame and the lower end of the first part, the battery locking mechanism comprises a locking unit and a limiting unit, the locking unit comprises a plurality of telescopic locking pins and a plurality of corresponding locking holes, and the limiting unit is arranged between the locking pins and the limiting unit. The moving directions of the locking pins are coplanar and different; according to the system, the reasonable design structure is adopted, the position of the battery replacing system on the rear frame is reasonably arranged, the problems that the view of a cab is shielded, a locking mechanism is complex and unreliable and the like can be effectively solved, and the performance and competitiveness of a host product can be improved.

    本发明涉及一种工程机械用换电系统,包括后车架、换电连接器底座及电池系统框架,电池系统框架包括第一部分、第二部分和第三部分,第一部分设置在后车架的上方,换电连接器底座安装在后车架上且位于第一部分的下方,第二部分和第三部分分别位于后车架的两侧,第一部分包括至少一层电池箱体框,后车架与第一部分的下端之间设置有电池锁定机构,电池锁定机构包括锁止单元和限位单元,锁止单元包括多个伸缩设置的锁止销以及对应的多个锁止孔,这些锁止销的移动方向共面不同向;该系统采用合理设计结构、合理布置换电系统在后车架上的位置,能够有效避免驾驶室视野被遮挡、锁止机构复杂不可靠等问题,有助于提升主机产品的性能和竞争力。
