The invention discloses a battery replacing device and a power utilization device for a battery pack, and the device comprises a rotary driving rod which is provided with a driving thread and can rotate in the circumferential direction; the pressing block is connected with the driving thread and is configured to be driven by the driving thread to move in the axial direction of the rotary driving rod; the connecting plate abuts against the pressing block and is configured to be driven by the pressing block to move in the axial direction of the rotary driving rod; and each lock rod comprises a rod body and a lock head, and the lock rods are symmetrically arranged on the connecting plate and are driven by the connecting plate to move in the axial direction so as to lock or loosen the battery pack. According to the invention, the more than two lock rods are arranged, and the more than two rotary driving rods are simultaneously driven by one rotary driving rod to lock or loosen the battery pack, so that the tensile force borne by each lock rod is reduced, and the lock rods are prevented from being broken due to overlarge tensile force.
本发明公开了一种电池包的换电装置及用电装置,包括旋转驱动杆,设置有驱动螺纹且可周向旋转;压块,与所述驱动螺纹连接,被配置为由所述驱动螺纹驱动沿所述旋转驱动杆的轴向移动;连接板,与所述压块相抵,被配置为由所述压块驱动沿所述旋转驱动杆的轴向移动;两个以的锁杆,包括杆体和锁头,所述锁杆对称设置于所述连接板上,由所述连接板驱动沿所述轴向移动以锁紧或松开电池包。本发明设置有两个以上的锁杆,通过一个旋转驱动杆同时驱动两个以上的旋转驱动杆锁紧或松开电池包,从而使每个锁杆所承受的拉力减少,避免锁杆因拉力过大而断裂。
