Abstract
An electric lifting frame includes a lifting pedestal and a remote control. The lifting pedestal includes a supporting base, a lifting rod detachably connected to the supporting base, and a transmission mechanism, a motor, a controller, and a power supply provided at the lifting rod. The motor is configured to effect extension and retraction of the lifting rod via the transmission mechanism. The controller is configured to control starting and stopping and a rotation direction of the motor. The power supply is configured to supply electric energy to the motor and the controller. The controller is further configured to determine a remaining capacity of the power supply and calculate a number of remaining available times of use according to the remaining capacity, a power of the motor, and a stroke of the transmission mechanism.
