The invention discloses a battery changing device and a power utilization device for a battery pack, and the device comprises a split type lock rod which comprises a rod body and a lock head, the diameter of the second end of the rod body is larger than that of the first end of the rod body, the periphery of the first end is provided with a first thread, and the lock head is connected with the first end through the first thread; the periphery of the first end is provided with a first thread, the periphery of the second end is provided with a second thread, and the rotary driving sleeve is connected with the second thread and used for driving the split lock rod to move in the axial direction so as to lock or loosen the battery pack; the shell is arranged on the outer side of the rod body and used for limiting the rod body to rotate in the circumferential direction along with the rotary driving sleeve. According to the lock rod, only the first threads for transmitting pressing force adopt fine threads with smaller diameters, so that the tensile life between the rod body and the lock head is prolonged; and the second end of the rod body adopts the second thread with a larger diameter, so that the wear resistance of the second thread can be improved.

    本发明公开了一种电池包的换电装置及用电装置,包括:分体式锁杆,包括杆体和锁头,杆体的第二端的直径大于所述杆体的第一端的直径,第一端的外周设置有第一螺纹,锁头与所述第一端通过所述第一螺纹连接,第二端的外周设置有第二螺纹,旋转驱动套,与第二螺纹连接,用于驱动分体式锁杆沿轴向移动以锁紧或松开所述电池包;壳体,设置于所述杆体的外侧,用于限制所述杆体随所述旋转驱动套周向旋转。本发明中锁杆只需要传递压紧力的第一螺纹采用直径较小的细牙,从而提高了杆体与锁头之间的抗拉寿命;而杆体的第二端采用直径较大的第二螺纹,从而可以提高了第二螺纹的耐磨性。
