ELECTRIC LIFTING/LOWERING MECHANISM

Disclosed is an electric lifting mechanism, which relates to height adjustable equipment and can present two different voltages via a common interface, thereby increasing an output power of a power share block. The electric lifting mechanism as disclosed includes a height adjustable platform, a human-machine interaction block, a controller arranged on the height adjustable platform, and a lifting column configured to drive the height adjustable platform to perform an up or down movement, the lifting column including a column and an electric motor driving the column to extend or retract, a human-machine interface being arranged on the controller, the human-machine interaction block being electrically connected to the human-machine interface; the controller includes a first power circuit and a second power circuit, the first power circuit being electrically connected to the human-machine interface to present a first supply voltage to the human-machine interaction block, the second power circuit presenting a second supply voltage to the electric motor; the electric lifting mechanism further includes a power share block arranged on the human-machine interaction block, the second power circuit being electrically connected to the human-machine interface to present the second supply voltage to the power share block so as to increase an output power of the power share block.
