The control system mainly includes a case member, a transformer and a central controller unit. Wherein, the transformer and the central controller unit are disposed in the case member, and electrically connected to a motor of the retractable foot via a plurality of conductive wires. Because the control systems required by the electric lifting desk is designed corresponding to the amounts of the foots, when the amounts of the foots are desired to be increased or decreased, a matched control system is required to be designed and fabricated again. As such, unnecessary time is wasted and no economic effect is provided. Moreover, when each conductive flat cable is collected and connected to the central controller unit, a situation of poor arrangement of the cables under the desk table is caused.

Accordingly, the applicant of the present disclosure has devoted himself for improving the mentioned shortages.

Accordingly, the present disclosure provides an electric deck frame structure, which includes at least four corner lifting vertical posts, at least four connection pipes, a transformer and a power and signal main cable. Each two of the corner lifting vertical posts are oppositely and spacedly arranged. Each of the corner lifting vertical posts includes a carrying seat and a retractable rod connected to the carrying seat. The carrying seat includes a first connection part and a second connection part. The first connection part is disposed with a first electric connection assembly. The second connection part is disposed with a second electric connection assembly electrically connected to the first electric connection assembly. Each of the connection pipes is connected to each of the corner lifting vertical posts. Two ends of each of the connection pipes are connected to the first connection part of one of the carrying seats and the second connection part of the another carrying seat adjacent to the carrying seat. One of the connection pipes is formed with a first opening and a second opening. The transformer has an electricity input port and an electricity output port.
