The invention provides a new energy automobile power battery expansion device which comprises a machine shell, a motor is fixedly connected to one side of the top surface of the machine shell, a threaded rod is fixedly connected to an output shaft of the motor, the outer surface of the threaded rod is sleeved with a first supporting plate, and the first supporting plate is in threaded connection with the outer surface of the threaded rod. The first supporting plate is slidably connected with a sliding groove in the top face of the machine shell, and a contact mechanism is arranged in an innercavity of the machine shell. In the invention, the motor drives the first sliding plate and the second sliding plate to be switched and communicated among the three groups of contact mechanisms, so that the two groups of power batteries do not influence each other after being switched, the complexity of a control system of the new energy automobile is reduced, and the reliability of operation is ensured.
本发明提供了一种新能源汽车动力电池扩展装置,包括机壳,所述机壳的顶面一侧固定连接有电机,所述电机的输出轴固定连接有螺纹杆,所述螺纹杆的外表面套设有第一支板,所述第一支板与所述螺纹杆的外表面螺纹连接,所述第一支板与所述机壳顶面的滑槽滑动连接,所述机壳的内腔里设置有触头机构。本发明中,电机带动第一滑板和第二滑板在三组触头机构之间切换连通,使得两组动力电池切换后互不影响,减少了新能源汽车的控制系统的复杂性,保证运行的可靠。
